Whereas mental health communities are divided about potentially problematic use patterns, many lay people identify as feeling dysregulated or compulsive in their use. Prior work has labeled this tendency perceived addiction to internet pornography (PA). This study's aims were to (1) assess the association between PA at baseline and other factors, including actual levels of average daily pornography use and personality factors and (2) assess the associations between baseline variables and PA 1 year later. DESIGN: Two large-scale community samples were assessed using online survey methods, with subsets of each sample being recruited for follow-up surveys 1 year later. SETTING: United States. PARTICIPANTS: Participants were adults who had used pornography within the past 6 months recruited in two samples. Sample 1 (n = 1507) involved undergraduate students from three US universities and sample 2 (n = 782) involved web-using adults. Subsets of each sample (sample 1, n = 146; sample 2, n = 211) were surveyed again 1 year later. MEASUREMENTS: At baseline, we assessed average daily pornography use, PA and relevant predictors (e.g. trait neuroticism, trait self-control, trait entitlement, religiousness, moral disapproval of pornography use). One year later, we assessed PA. FINDINGS: Cross-sectionally, PA was correlated strongly with moral disapproval of pornography use [sample 1, Pearson's correlation: r = 0.68 (0.65, 0.70); sample 2, r = 0.58 (0.53, 0.63)]. Baseline moral disapproval [sample 1, r = 0.46 (0.33, 0.56); sample 2, r = 0.61 (0.51, 0.69)] and perceived addiction demonstrated relationships with perceived addiction 1 year later. We found inconclusive evidence of a substantial or significant association between pornography use and perceived addiction over time [sample 1, r = 0.13 (-0.02, 0.28); sample 2, r = 0.11 (-0.04, 0.25)].

Method: Two hundred sixty-nine participants were recruited online from chronic pain organizations, websites, social media sites, and discussion forums. Those who met criteria for inclusion were presented with a variety of measures related to pain, sexual functioning, and relationship satisfaction (for those in a relationship), as well as cognitive and affective variables. Results: Participant mean age was 37 years, and the majority were female, heterosexual, and currently in a relationship. High levels of pain severity and interference from pain, fatigue, depression, anxiety, stress, and body image concerns were reported, along with low levels of self-esteem and pain self-efficacy. In addition, substantial proportions of male (43\%) and female (48\%) respondents had scores indicative of sexual problems. Exploratory hierarchical regression analyses revealed that, for women, age and relationship satisfaction (which were both treated as covariates) as well as depression emerged as statistically significant correlates of sexual functioning (i.e., women who were older and reported greater levels of depression and less satisfaction with their current relationship indicated poorer sexual functioning). When relationship satisfaction was the criterion measure, age and sexual functioning (again, treated as covariates) and perceived stress emerged as significant (i.e., women who were older, reported poorer sexual functioning, and reported greater perceived stress also indicated being less satisfied with their current relationship). For male participants, age emerged as the only statistically significant correlate of sexual functioning (i.e., older men reported poorer functioning). In terms of relationship satisfaction, self-esteem was the lone significant correlate variable (men who reported lower self-esteem also were less satisfied with their current relationship). Conclusions: Some sex differences were evident in the variables that predict sexual difficulties and relationship satisfaction among those suffering from chronic pain. Of note is that when psychological variables were considered, pain-specific physical variables (e.g., pain severity and activity limitations) accounted for very little additional variance.}, language = {eng}, number = {5}, journal = {Pain Medicine (Malden, Mass.)}, author = {Finn, Erica and Morrison, Todd G. and McGuire, Brian E.}, month = may, year = {2018}, pmid = {29741742}, keywords = {Adaptation, Psychological, Adolescent, Adult, Aged, Chronic Pain, Depression, Female, Humans, Male, Middle Aged, Personal Satisfaction, Self Concept, Self Efficacy, Sex Factors, Sexual Behavior, Sexual Partners, Surveys and Questionnaires, Young Adult}, pages = {942--954}, }

DATA SOURCES:: A systematic review of the literature was undertaken, searching EMBASE, PSYCHinfo, MEDLINE, and CINAHL. Experts in the field were contacted to identify unpublished studies. STUDY SELECTION:: Exclusion criteria: Studies with participants above age 18 or drawn from a neonatal ICU, studies not in English, and those not measuring psychopathology. DATA EXTRACTION:: Seven hundred fifty-three articles initially identified were hand searched which identified three studies, with a further three studies found by contacting experts in the field. Of these, three were randomized controlled trials and three feasibility studies. DATA SYNTHESIS:: The interventions primarily targeted parents (particularly mothers), with the aim of reducing psychopathology especially posttraumatic stress disorder. Findings from these few studies demonstrated that interventions can lead to a reduction in parent and child psychopathology. Key ingredients of these interventions included psychoeducation, parent support after discharge, offering intervention to those families at high risk of developing psychopathology as identified by screening at the point of discharge, follow-up of all families with the aim of case finding, and specific interventions to target posttraumatic stress disorder symptoms. CONCLUSIONS:: Intervention studies are few but do lead to reductions in parent and child psychopathology. There is sufficient information to suggest some of these interventions could be supported and further evaluated.

Elevated CVP and abnormal lymphatic drainage are implicated in severe Fontan complications, including protein losing enteropathy (PLE) and plastic bronchitis (PB). Systematic studies of TD and lymphatic circulation in children are limited, and their cervical TD normative values have not been established. METHODS: Thoracic duct imaging was attempted prospectively during routine echocardiograms performed 7/2014-9/2016 in children 5-21 years old with normal cardiovascular physiology and Fontan palliation. TD insertion to the central venous system (lympho-venous junction) was assessed with an S12-4 MHz transducer. For the first 34 patients, only TD ostia were measured, but ostium shape variability at the lympho-venous junction led to including the TD arch 5-10 mm proximal to the ostium for the remaining cohort. RESULTS: Seventy-nine total subjects were studied: 58 controls, 13 Fontan patients with normal systemic ventricular ejection fraction (EF) ({\textgreater}50\%), and 8 Fontan patients with decreased EF (≤50\%). Combined Fontan subjects had larger TD ostial diameters compared to controls when normalized by body surface area (median 2.6 mm/m2 vs. 2 mm/m2 ) (P=.04). CONCLUSION: To our knowledge, this is the first systematic study of ultrasonographic TD imaging in children. Fontan patients have larger TD diameters, reflecting the impaired lymphatic circulation in patients with this physiology. Further research may provide important associations between sonographic TD features with the functional status of patients with Fontan circulation.}, language = {eng}, number = {9}, journal = {Echocardiography}, author = {Sung, C and Bass, JL and Berry, JM and Shepard, CW and Lindgren, B and Kochilas, LK}, month = sep, year = {2017}, keywords = {Young Adult}, pages = {1347--1352} }

Neuroimaging studies comparing unaffected youth at high familial risk for BD (i.e., those with a first-degree relative with the disorder; termed "high-risk" [HR]) to "low-risk" (LR) youth (i.e., those without a first-degree relative with BD) and to patients with BD may help identify potential brain-based markers associated with risk (i.e., regions where HR+BD≠LR), resilience (HR≠BD+LR), or illness (BD≠HR+LR). METHOD: During functional magnetic resonance imaging (fMRI), 99 youths (i.e., adolescents and young adults) aged 9.8 to 24.8 years (36 BD, 22 HR, 41 LR) performed a task probing face emotion labeling, previously shown to be impaired behaviorally in youth with BD and HR youth. RESULTS: We found three patterns of results. Candidate risk endophenotypes (i.e., where BD and HR shared deficits) included dysfunction in higher-order face processing regions (e.g., middle temporal gyrus, dorsolateral prefrontal cortex). Candidate resilience markers and disorder sequelae (where HR and BD, respectively, show unique alterations relative to the other two groups) included different patterns of neural responses across other regions mediating face processing (e.g., fusiform), executive function (e.g., inferior frontal gyrus), and social cognition (e.g., default network, superior temporal sulcus, temporo-parietal junction). CONCLUSION: If replicated in longitudinal studies and with additional populations, neural patterns suggesting risk endophenotypes could be used to identify individuals at risk for BD who may benefit from prevention measures. Moreover, information about risk and resilience markers could be used to develop novel treatments that recruit neural markers of resilience and attenuate neural patterns associated with risk.

The aim of this study is to investigate the impact of the time interval between port placement and initiation of chemotherapy and the neutropenia-inducing potential of the chemotherapy administered upon complication-related port removal. PATIENTS AND METHODS: Between January 2010 and December 2013, 4045 consecutive patients were included in this observational, single-center prospective study. The chemotherapy regimens were classified as having a low ({\textbackslash}textbackslashtextless10\%), intermediate (10-20\%), or high ({\textbackslash}textbackslashtextgreater20\%) risk for inducing neutropenia. RESULTS: The overall removal rate due to complications was 7.2\%. Among them, port-related infection (2.5\%) and port expulsion (1\%) were the most frequent. The interval between port insertion and its first use was shown to be a predictive factor for complication-related removal rates. A cut-off of 6 days was statistically significant (p = 0.008), as the removal rate for complications was 9.4\% when this interval was 0-5 days and 5.7\% when it was {\textbackslash}textbackslashtextgreater/=6 days. Another factor associated with port complication rate was the neutropenia-inducing potential of the chemotherapy regimens used, with removal for complications involved in 5.5\% of low-risk regimens versus 9.4\% for the intermediate- and high-risk regimens (p = 0.003). CONCLUSION: An interval of 6 days between placement and first use of the port reduces the removal rate from complications.

We examined associations between the development of NAb and the occurrence of superinfection in a well-characterized, antiretroviral therapy (ART)-naive, primary infection cohort of men who have sex with men. Deep sequencing was applied to blood plasma samples from the cohort to detect cases of superinfection. We compared the NAb activity against autologous and heterologous viruses between 10 participants with intrasubtype B superinfection and 19 monoinfected controls, matched to duration of infection and risk behavior. Three to 6 months after primary infection, individuals who would later become superinfected had significantly weaker NAb activity against tier 1 subtype B viruses (P = 0.003 for SF-162 and P = 0.017 for NL4-3) and marginally against autologous virus (P = 0.054). Lower presuperinfection NAb responses correlated with weaker gp120 binding and lower plasma total IgG titers. Soon after superinfection, the NAb response remained lower, but between 2 and 3 years after primary infection, NAb levels strengthened and reached those of controls. Superinfecting viruses were typically not susceptible to neutralization by presuperinfection plasma. These observations suggest that recently infected individuals with a delayed NAb response against primary infecting and tier 1 subtype B viruses are more susceptible to superinfection.IMPORTANCE Our findings suggest that within the first year after HIV infection, a relatively weak neutralizing antibody response against primary and subtype-specific neutralization-sensitive viruses increases susceptibility to superinfection in the face of repeated exposures.

Our aim was to follow-up a cohort of patients presenting to hospital from the community with AKI (community-acquired AKI [c-AKI]), detected through the use of e-alerts, and describe their short-term outcomes regardless of whether they were subsequently admitted to hospital. Methods: Blood samples for all hospital attenders from the community either to the Accidents and Emergency department or one of the acute care areas of the hospital during a 6-month period (November 1, 2013-April 30, 2014) were screened for presence of c-AKI using a locally developed e-alerts system based on Kidney Disease: Improving Global Outcomes criteria. Follow-up data were obtained for a period of 3 months. Results: A total of 1,277 c-AKI episodes were identified in 1,185 patients (incidence 579 per 100,000 persons). Episodes that lead to hospitalization (n = 1,096 [86\%]) were associated with a median length of hospital stay of 6.6 days; a graded increase in duration of stay was noted with increasing severity of AKI. Acute dialysis was needed during 21 (1.6\%) episodes. For mortality rates, only the first AKI episode was considered. There were 298 deaths within 30 days of diagnosis irrespective of admissions status (30-day mortality rate: 25\%). Conclusions: Using e-alerts in acute care settings to detect c-AKI is novel and may be used to stage and follow-up AKI using existing diagnostic criteria. c-AKI is relatively common and leads to significant mortality. © 2016 S.

Previous studies showed mixed results in relation to association between socioeconomic status and obesity in the country. The current study aimed to examine educational inequalities among adults in Tehran in 2011. METHOD: Data on 90,435 persons 18 years and older from Urban Health Equity Assessment and Response Tool (Urban HEART-2) were analyzed. The Slope Index of Inequality (SII) and the Relative Index of Inequality (RII) were used for assessing educational inequalities in obesity. These measures were quantified using generalized linear models for the binomial family adjusted for sex and age. Subgroup analysis was conducted across sex, age groups and the 22 districts of Tehran. RESULTS: Both SII and RII showed substantial educational inequalities in obesity in favour of more educated adults [RII and SII (95\% CI were equal to 2.91 (2.71-3.11) and 0.12 (0.12-0.13)), respectively]. These educational inequalities were persistent even after adjusting for employment, marital status and smoking. Subgroup analysis revealed that educational inequalities were more profound among women. While among men educational inequalities were generally increasing with age, an inverse trend was observed among women. Educational inequalities were observed within all 22 districts of Tehran and generally there were no statistically significant differences between districts. CONCLUSION: An inverse association between education and obesity was observed in the current study. To decrease educational inequalities in Tehran, priority should be given to younger women and older men. Further analyses are needed to explain these inequalities.}, language = {eng}, journal = {Obesity Research \& Clinical Practice}, author = {Kiadaliri, Aliasghar A. and Asadi-Lari, Mohsen and Kalantari, Naser and Jafari, Mehdi and Vaez Mahdavi, Mohammad Reza and Faghihzadeh, Soghrat}, month = sep, year = {2016}, pmid = {26003304}, keywords = {Adolescent, Adult, Aged, Aged, 80 and over, Educational Status, Educational inequality, Female, Generalized linear model, Humans, Iran, Male, Middle Aged, Obesity, Sex Factors, Social Class, Socioeconomic Factors, Urban-HEART, Young Adult}, pages = {S57--S63}, }

We conducted this case-control study to determine the risk factors and treatment outcome of infections due to carbapenem resistant Enterobacteriaceae in our institution. Methods. This is a matched case-control study of patients with infection due to carbapenem resistant Enterobacteriaceae (CRE) and carbapenem susceptible Enterobacteriaceae (CSE), from Riyadh, Saudi Arabia, between March 2012 and December 2013. Results. During this period, 29 cases and 58 controls were studied. The mean ages of the cases (55.4 years) and controls (54.7 years) were similar (p = 0.065). Cases had higher mean Charlson comorbidity index (CCI) (3.1) than controls (1.9), p = 0.026. Several factors contributed to infection among the studied population. Prior uses of piperacillin-tazobactam, a carbapenem, a quinolone, and metronidazole were significantly associated with CRE infections. Nine of the cases died compared with 7 of the controls, p = 0.031. Mortality was associated with advanced age, the presence of comorbidities, ICU stay, and receipt of invasive procedures.

Parasternal block and transcutaneous electrical nerve stimulation (TENS) have been demonstrated to produce effective analgesia and reduce postoperative opioid requirements in patients undergoing cardiac surgery. Objectives. To compare the effectiveness of TENS and parasternal block on early postoperative pain after cardiac surgery. Methods. One hundred twenty patients undergoing cardiac surgery were enrolled in the present randomized, controlled prospective study. Patients were assigned to three treatment groups: parasternal block, intermittent TENS application, or a control group. Results. Pain scores recorded 4h, 5h, 6h, 7h, and 8h postoperatively were lower in the parasternal block group than in the TENS and control groups. Total morphine consumption was also lower in the parasternal block group than in the TENS and control groups. It was also significantly lower in the TENS group than in the control group. There were no statistical differences among the groups regarding the extubation time, rescue analgesic medication, length of intensive care unit stay, or length of hospital stay. Conclusions. Parasternal block was more effective than TENS in the management of early postoperative pain and the reduction of opioid requirements in patients who underwent cardiac surgery through median sternotomy.

OBJECTIVE: To examine the magnitude at which strabismus is detectable by lay observers in an ethnically diverse set of images. DESIGN, SETTING, AND PARTICIPANTS: Photographs of 12 ethnically diverse models (black, white, and Asian) were simulated to have strabismus from esotropia of 21 prism diopters (∆) to exotropia of 21∆. From July 1, 2007, to October, 1, 2008, images were presented to 120 non-health care professionals aged 21 years or older from the general community in Boston, Massachusetts, who were asked whether strabismus was present. Analysis was conducted from November 1, 2008, to March 31, 2009. MAIN OUTCOMES AND MEASURES: The threshold angle for detecting strabismus to enable 70\% of lay observers to make a positive determination whether strabismus is present. RESULTS: In white and black models, the threshold allowing a 70\% positive detection rate was higher for esotropia than for exotropia (P {\textless} .001 for both). For white models, the threshold was 23.2∆ (95\% CI, 21.0∆ to 26.5∆) for esotropia and 13.5∆ (95\% CI, 12.5∆ to 14.6∆) for exotropia. For black models, the threshold was 20.8∆ (95\% CI, 19.2∆ to 22.2∆) for esotropia and 16.3∆ (95\% CI, 15.5∆ to 17.2∆) for exotropia. Asian models showed an opposite trend, with the threshold allowing a 70\% positive detection rate for esotropia (14.3∆; 95\% CI, 13.2∆ to 15.7∆) being lower than that for exotropia (20.9∆; 95\% CI, 18.0∆ to 24.6∆) (P {\textless} .001). CONCLUSIONS AND RELEVANCE: Esotropia was easier for lay observers to detect than exotropia in Asian models, and exotropia was easier to detect than esotropia in white and black models. This information should be considered when managing patients who have concerns about the social significance of their strabismus.

The aims of our study were as follows: to characterise concomitant procedures performed during adult congenital cardiac surgery, and to better define the risk involved with performing concomitant procedures during a single operation. METHODS: We retrospectively studied 458 adult congenital cardiac surgical patients. Major procedures were characterised as aortic, mitral, pulmonary, tricuspid, septal defect, single ventricle, transplant, and others. We constructed logistic regression models to assess the risk for mortality, major adverse event, and prolonged length of stay. RESULTS: A total of 362 operations involved a single major procedure, whereas 96 involved concomitant procedures. Performing concomitant procedures increased mortality (7.3 versus 2.5\%), major adverse events (21.8 versus 14.9\%), and prolonged length of stay (29.2 versus 17.1\%). The added risks of concomitant procedures on mortality, major adverse event, and prolonged length of stay were 2.9 (95\% CI 1.0-8.5, p=0.05), 1.9 (95\% CI 1.1-3.3, p=0.02), and 2.4 (95\% CI 1.4-4.1, p=0.003), respectively. There were 200 patients with conotruncal anomalies who underwent pulmonary valve surgery. In this subset, the added risks of concomitant procedures in addition to pulmonary valve surgery on mortality, major adverse events, and prolonged length of stay were 6.6 (95\% CI 1.2-37.3, p=0.03), 2.8 (95\% CI 1.2-6.6, p=0.03), and 3.3 (95\% CI 1.5-7.4, p=0.005), respectively.

The inclusion of multiple explanatory variables in the models provides the opportunity to calculate Z-scores that are adjusted with respect to the relevant anthropometric parameters. INTRODUCTION: Previous descriptions of children's bone mineral measurements by age have focused on segmenting diverse populations by race and sex without adjusting for anthropometric variables or have included the effects of a single anthropometric variable. METHODS: We applied multivariate semi-metric smoothing to the various pediatric bone-measurement sites using data from the Bone Mineral Density in Childhood Study to evaluate which of sex, race, age, height, weight, percent body fat, and sexual maturity explain variations in the population's bone mineral values. By balancing high adjusted R(2) values with clinical needs, two models are examined. RESULTS: At the spine, whole body, whole body sub head, total hip, hip neck, and forearm sites, models were created using sex, race, age, height, and weight as well as an additional set of models containing these anthropometric variables and percent body fat. For bone mineral density, weight is more important than percent body fat, which is more important than height. For bone mineral content, the order varied by site with body fat being the weakest component. Including more anthropometrics in the model reduces the overlap of the critical groups, identified as those individuals with a Z-score below -2, from the standard sex, race, and age model. CONCLUSIONS: If body fat is not available, the simpler model including height and weight should be used.

However, in many cases, it would be more practical for interventions to be delivered after wounding. This preliminary study investigated whether a brief relaxation intervention could improve healing when administered either before or after skin damage produced by tape stripping in comparison to a control group. METHODS: One hundred twenty-one healthy adults were randomized into one of three groups: (a) relaxation prestripping group, (b) relaxation poststripping group, or (c) no relaxation. Participants completed measures of stress, fatigue, relaxation, and pain. Relaxation consisted of listening to 20 minutes of guided relaxation, whereas the control condition was quiet reading for 20 minutes. Skin barrier function was measured using transepidermal water loss at baseline, immediately after tape stripping and 25 minutes later. RESULTS: Relaxation either before or after tape stripping improved skin barrier recovery compared with the control group (F(2,92) = 3.58, p = .032, partial η = 0.074). Participants who took part in the relaxation intervention were significantly more relaxed and reported greater reductions in pain than the control group did 25 minutes after tape stripping. Perceived stress over the last month was not significantly related to healing. CONCLUSIONS: This study showed that a relaxation intervention had a beneficial effect on skin barrier recovery regardless of whether the intervention was administered before or after wounding.

Along international borders, like the San Diego-Tijuana region, understanding the dynamics of HIV transmission across reported risks, racial/ethnic groups, and geography can help direct effective prevention efforts on both sides of the border. METHODS: We gathered sociodemographic, geographic, clinical, and viral sequence data from HIV infected individuals participating in ten studies in the San Diego-Tijuana border region. Phylogenetic and network analysis was performed to infer putative relationships between HIV sequences. Correlates of identified clusters were evaluated and spatiotemporal relationships were explored using Bayesian phylogeographic analysis. FINDINGS: After quality filtering, 843 HIV sequences with associated demographic data and 263 background sequences from the region were analyzed, and 138 clusters were inferred (2-23 individuals). Overall, the rate of clustering did not differ by ethnicity, residence, or sex, but bisexuals were less likely to cluster than heterosexuals or men who have sex with men (p = 0.043), and individuals identifying as white (p ≤ 0.01) were more likely to cluster than other races. Clustering individuals were also 3.5 years younger than non-clustering individuals (p {\textless} 0.001). Although the sampled San Diego and Tijuana epidemics were phylogenetically compartmentalized, five clusters contained individuals residing on both sides of the border. INTERPRETATION: This study sampled {\textasciitilde} 7\% of HIV infected individuals in the border region, and although the sampled networks on each side of the border were largely separate, there was evidence of persistent bidirectional cross-border transmissions that linked risk groups, thus highlighting the importance of the border region as a "melting pot" of risk groups.

A well-described age-related alteration of the immune system is the decrease of de novo generation of T and B cells. In addition, the accumulation of memory cells and loss of diversity in antigen specificities resulting from a lifetime of exposure to pathogens has also been described. However, the effect of aging on subsets of γδTCR(+) T cells and Tregs has been poorly described, and the efficacy of the recall response to common persistent infections in the elderly remains obscure. Here, we investigated alterations in the subpopulations of the B and T cells among 24 healthy young (aged 19-30) and 26 healthy elderly (aged 53-67) individuals. The analysis was performed by flow cytometry using freshly collected peripheral blood. γδTCR(+) T cells were overall decreased, while CD4(+)CD8(-) cells among γδTCR(+) T cells were increased in the elderly. Helios(+)Foxp3(+) and Helios(-)Foxp3(+) Treg cells were unaffected with age. Recent thymic emigrants, based on CD31 expression, were decreased among the Helios(+)Foxp3(+), but not the Helios(-)Foxp3(+) cell populations.

However, no specific theory-driven relationships between microstructural white matter disruptions and cognition have been established in CHD. We conducted a two-part study. First, we identified significant differences in fractional anisotropy (FA) of emerging adults with CHD using Tract-Based Spatial Statistics (TBSS). TBSS analyses between 22 participants with CHD and 18 demographically similar controls identified five regions of normal appearing white matter with significantly lower FA in CHD, and two higher. Next, two regions of lower FA in CHD were selected to examine theory-driven differential relationships with cognition: voxels along the left uncinate fasciculus (UF; a tract theorized to contribute to verbal memory) and voxels along the right middle cerebellar peduncle (MCP; a tract previously linked to attention). In CHD, a significant positive correlation between UF FA and memory was found, r(20)=.42, p=.049 (uncorrected). There was no correlation between UF and auditory attention span. A positive correlation between MCP FA and auditory attention span was found, r(20)=.47, p=.027 (uncorrected). There was no correlation between MCP and memory. In controls, no significant relationships were identified. These results are consistent with previous literature demonstrating lower FA in younger CHD samples, and provide novel evidence for disrupted white matter integrity in emerging adults with CHD. Furthermore, a correlational double dissociation established distinct white matter circuitry (UF and MCP) and differential cognitive correlates (memory and attention span, respectively) in young adults with CHD.}, language = {eng}, number = {1}, journal = {J Int Neuropsychol Soc}, author = {Brewster, RC and King, TZ and Burns, TG and Drossner, DM and Mahle, WT}, month = jan, year = {2015}, keywords = {Young Adult}, pages = {22--33} }

OBJECTIVES: To measure Achilles tendon microcirculation (total hemoglobin [THb] and oxygen saturation [StO2]) before and after the application of a physical agent in asymptomatic participants, and to compare differences between application location and physical agent dosage. BACKGROUND: Tendon microcirculation can be altered by superficial heating or cryotherapy. METHODS: Fifty-one healthy adults (median age, 22 years; range, 20-34 years) were recruited and randomly assigned into 1 of 4 groups. Participants in each group received an intervention consisting of 1 of the following 4 physical agents: ultrasound (n = 12), interferential current (n = 14), low-level laser (n = 11), or vibration massage (n = 14). In each group, the selected intervention was applied at 2 different doses (ultrasound, 0.8 or 1.2 W/cm(2); laser, 5.4 or 18 J) or target locations (vibration and electrostimulation, calf muscle or Achilles tendon). For each participant, each dose or target location was randomly applied to 1 randomly selected lower leg (each leg receiving only 1 of the 2 options). RESULTS: The StO2 values significantly increased after ultrasound at both doses (P{\textless}.008), and the THb value significantly increased for the higher dose only (P{\textless}.008). Both THb and StO2 values also significantly increased in response to vibration massage targeting the Achilles tendon (P{\textless}.008), and these values were greater than those resulting from the vibration massage applied to the calf muscle (P = .003 and .002, respectively). No significant THb and StO2 differences were found after the application of interferential current or low-level laser. CONCLUSION: Tendon microcirculation increases after ultrasound and vibration massage intervention concentrated on the Achilles tendon.

We analyzed prospective areal BMD (aBMD) and bone mineral content (BMC) data from the Bone Mineral Density in Childhood Study (n = 603, European ancestry, 54\% female). Linear mixed models were used to assess if 77 single-nucleotide polymorphisms (SNPs) near known adult BMD susceptibility loci interacted with sex and pubertal stage to influence the aBMD/BMC; adjusting for age, BMI, physical activity, and dietary calcium. The strongest main association was observed between an SNP near C7orf58 and distal radius aBMD. However, this association had a significant sex • SNP interaction, revealing a significant association only in females (b = -0.32, p = 1.8 × 10(-6)). Furthermore, the C12orf23 locus had significant interactions with both sex and pubertal stage, revealing associations in females during Tanner stage I for total hip aBMD (b = 0.24, p = 0.001) and femoral neck aBMD (b = 0.27, p = 3.0 × 10(-5)). In contrast, the sex • SNP interactions for loci near LRP5 and WNT16 uncovered associations that were only in males for total body less head BMC (b = 0.22, p = 4.4 × 10(-4)) and distal radius aBMD (b = 0.27, p = 0.001), respectively.

Consensus guidelines have recommended echocardiographic screening of first-degree relatives. The utility of this approach in siblings of children with BAV is not known. The objective of this study is to evaluate the yield of routine screening of siblings of children with BAV and undertake an economic analysis of this practice. METHODS: Siblings of children with BAV who underwent echocardiographic screening in a single pediatric cardiology practice were identified. The anatomic features and hemodynamics of siblings newly diagnosed with BAV were recorded. A Markov model was constructed to determine cost-effectiveness ratios, and sensitivity analyses were performed. RESULTS: There were 207 screened siblings of 181 children with BAV. The median age at screening was 7 years. BAV was identified in 21 (10.1\%) of siblings screened. The median peak Doppler gradient was 18 mm Hg. Aortic insufficiency was mild or less in all. The mean cost to diagnose BAV in a sibling was \$2109 per new case found. The estimated mean cost to avert a single aortic dissection in the third or fourth decade of life was \$363 911. The estimated cost per life-year saved was \$74 884 and ranged from \$17 461 to \$1 136 536 in sensitivity analysis. CONCLUSIONS: Echo screening among siblings of those with BAV is effective and inexpensive and may lower the risk of the complications of such as dissection, although it comes at a moderate cost relative to benefits gained.

As revealed by many cases worldwide, such a marketing strategy led to unintentional self-poisonings and deaths. FIPs therefore constitute a very serious health and public policy issue. To understand why FIPs are a threat, we first conducted a qualitative analysis on real-life cases of household cleaners and personal care products-related phone calls at a poison control center followed by a behavioral experiment. Unintentional self-poisoning in the home following the accidental ingestion of a hygiene product by a healthy adult is very likely to result from these products being packaged like foodstuffs. Our hypothesis is that FIPs are non-verbal food metaphors that could fool the brain of consumers. We therefore conducted a subsequent functional neuroimaging (fMRI) experiment that revealed how visual processing of FIPs leads to cortical taste inferences. Considered in the grounded cognition perspective, the results of our studies reveal that healthy adults can unintentionally categorize a personal care product as something edible when a food-like package is employed to market nonedible and/or dangerous products. Our methodology combining field (qualitative) and laboratory (behavioral and functional neuroimaging) findings could be of particular relevance for policy makers, as it can help screening products prior to their market release--e.g. the way they are packaged and how they can potentially confuse the mind of consumers--and therefore save lives.}, language = {eng}, number = {9}, journal = {PloS One}, author = {Basso, Frédéric and Robert-Demontrond, Philippe and Hayek, Maryvonne and Anton, Jean-Luc and Nazarian, Bruno and Roth, Muriel and Oullier, Olivier}, year = {2014}, pmid = {25207971}, pmcid = {PMC4160172}, keywords = {Adult, Aged, Aged, 80 and over, Behavior, Brain, Cosmetics, Drinking, Female, Food, Functional Neuroimaging, Hair Preparations, Humans, Magnetic Resonance Imaging, Male, Marketing, Middle Aged, Poison Control Centers, Public Health, Safety, Young Adult}, pages = {e100368} }

Such a feedback may motivate patients to keep increasing the amount of exercise they perform, thus facilitating their recovery during physical rehabilitation therapy. In this work, we propose a novel wearable and affordable system which can predict different postures of the upper-extremities by classifying force myographic (FMG) signals of the forearm in real-time. METHODS: An easy to use force sensor resistor (FSR) strap to extract the upper-extremities FMG signals was prototyped. The FSR strap was designed to be placed on the proximal portion of the forearm and capture the activities of the main muscle groups with eight force input channels. The non-kernel based extreme learning machine (ELM) classifier with sigmoid based function was implemented for real-time classification due to its fast learning characteristics. A test protocol was designed to classify in real-time six upper-extremities postures that are needed to successfully complete a drinking task, which is a functional exercise often used in constraint-induced movement therapy. Six healthy volunteers participated in the test. Each participant repeated the drinking task three times. FMG data and classification results were recorded for analysis. RESULTS: The obtained results confirmed that the FMG data captured from the FSR strap produced distinct patterns for the selected upper-extremities postures of the drinking task. With the use of the non-kernel based ELM, the postures associated to the drinking task were predicted in real-time with an average overall accuracy of 92.33% and standard deviation of 3.19%. CONCLUSIONS: This study showed that the proposed wearable FSR strap was able to detect eight FMG signals from the forearm. In addition, the implemented ELM algorithm was able to correctly classify in real-time six postures associated to the drinking task. The obtained results therefore point out that the proposed system has potential for providing instant feedback during functional rehabilitation exercises.}, bibtype = {article}, author = {Xiao, Zhen G and Menon, Carlo}, journal = {Journal of neuroengineering and rehabilitation} }

Hepcidin quantification in human serum provides new insights for the pathogenesis of disorders of iron homeostasis. This study describes an ELISA immunoassay for hepcidin quantification in human serum and reference ranges for Bulgarian population. METHODS: We used a sandwich ELISA method from USCN Life Science inc. that consists of ready to use, pre-coated 96-well strip plate with 2 antihepcidin-25 monoclonal antibodies. A recombinant Hepcidin in 16 μg/L concentration is used as a standard. We correlated ELISA results of hepcidin-25 measurements in healthy population to ferritin, hemoglobin concentration in reticulocytes, transferrin, and iron levels. RESULTS: The sandwich ELISA was highly specific for hepcidin-25.

We sought to establish an electrocardiographic screening tool to identify children with HC. We hypothesized that a pediatric-specific electrocardiographic criterion would perform better than the popular criteria used for screening children for left ventricular hypertrophy and HC. The earliest available electrocardiogram for children (n=108) with HC (ages 7 to 21 yrs) was reviewed. We sought to compare the diagnostic accuracy of 4 screening algorithms: (1) Sokolow-Lyon criterion (SV1+RV5/RV6{\textgreater}35 mm), (2) Cornell criterion (RaVL+SV3{\textgreater}28 mm in men, 20 mm in women), (3) total 12-lead voltage criterion (R wave to the nadir of Q/S wave{\textgreater}175 mm), and (4) pediatric-specific criterion (RaVL+SV2{\textgreater}23 mm). The same criteria were applied to a cohort of age-matched and gender-matched controls without cardiac disease. Statistically significant correlations were found between children with HC and positive screen using all 4 criteria. However, comparison of receiver operating characteristic demonstrated an area under the curve of 0.67 for Sokolow-Lyon criterion, 0.70 for Cornell criterion, 0.83 for total 12-lead criterion, and 0.82 for pediatric-specific criterion. Pediatric-specific criterion had superior sensitivity in gene-positive children and superior overall specificity than total 12-lead criterion.

In the first, participants completed visuospatial 0-back and 2-back tasks during the encoding of information to be remembered. The concurrent tasks did not differentially disrupt performance on backward digit recall, relative to forward digit recall. Experiment 2 shifted concurrent load to the recall phase instead and, in this case, revealed a larger effect of both tasks on backward recall, relative to forwards recall, suggesting that backward recall may draw on additional resources during the recall phase and that these resources are visuospatial in nature. Experiments 3 and 4 then further investigated the role of visual processes in forward and backward recall using dynamic visual noise (DVN). In Experiment 3, DVN was presented during encoding of information to be remembered and had no effect upon performance. However, in Experiment 4, it was presented during the recall phase, and the results provided evidence of a role for visual imagery in backward digit recall.

The standard EORTC QoL Questionnaire C30 (EORTC QLQ-C30) and the EORTC QLQ-Brain Cancer Module (QLQ-BN20) were used. 64 adult patients with intracranial ependymomas were included in the study. The only factor that was associated with increased survival was age <55 years (p < 0.001). Supratentorial location was correlated with shorter progression free survival than infratentorial location (PFS; p = 0.048). In WHO Grade II tumors local irradiation did not lead to increased PFS (p = 0.888) or overall survival (p = 0.801). Even for incompletely resected Grade II tumors local irradiation did not lead to a benefit in PFS (p = 0.911). In a multivariate analysis of QoL, irradiated patients had significantly worse scores in the item "fatigue" (p = 0.037) than non-irradiated patients. Here we present QoL data of adult patients with intracranial ependymomas. Our data show that local radiation therapy may have long-term effects on patients' QoL. Since in the incompletely resected Grade II tumors local irradiation did not lead to a benefit in PFS in this retrospective study, prospective randomized studies are necessary. In addition to age, supratentorial tumor location is associated with a worse prognosis in adult ependymoma patients.}, bibtype = {article}, author = {Dützmann, Stephan and Schatlo, Bawarjan and Lobrinus, Alexander and Murek, Michael and Wostrack, Maria and Weiss, Carolin and Schaller, Karl and Raabe, Andreas and Meyer, Bernhard and Goldbrunner, Roland and Franz, Kea and Seifert, Volker and Senft, Christian}, journal = {Journal of Neuro-Oncology}, number = {3} }

We investigated associations of symptoms and consultation frequency in primary care with TYA cancers. METHODS: Population-based, case-control study was carried out using data from the Clinical Practice Research Datalink (CPRD). A total of 1064 TYA diagnosed with cancer were matched to 13,206 controls. Symptoms independently associated with specific cancers were identified. Likelihood ratios (LRs) and positive predictive values (PPVs) were calculated. RESULTS: In the 3 months before diagnosis, 397 (42.9\%) cases consulted {\textgreater} or =4 times vs 593(11.5\%) controls (odds ratio (OR): 12.1; 95\% CI: 9.7, 15.1), yielding a PPV for any cancer of 0.018\%. The LR of lymphoma with a head/neck mass was 434 (95\% CI: 60, 3158), with a PPV of 0.5\%.

The aim of this study was therefore, twofold: to use linked primary and secondary care data to determine an optimum definition for estimating the incidence of first VTE in and around pregnancy; and secondly to conduct a systematic literature review of studies on perinatal VTE incidence with the purpose of comparing our estimates. METHODS: We used primary care data from the Clinical Practice Research Datalink (CPRD), which incorporates linkages to secondary care contained within Hospital Episode Statistics (HES) between 1997 and 2010 to estimate the incidence rate of VTE in the antepartum and postpartum period. We systematically searched the literature on the incidence of VTE during antepartum and postpartum periods and performed a meta-analysis to provide comparison. FINDINGS: Using combined CPRD and HES data and a restrictive VTE definition, the absolute rate during the antepartum period and first six weeks postpartum (early postpartum) were 99 (95\%CI 85-116) and 468 (95\%CI 391-561) per 100,000 person-years respectively. These were comparable to the pooled estimates from our meta-analysis (using studies after 2005) during the antepartum period (118/100,000 person-years) and early postpartum (424/100,000 person-years). When we used only secondary care data to identify VTE events, incidence was lower during the early postpartum period (308/100,000 person-years), whereas relying only on primary care data lead to lower incidence during the time around delivery, but higher rates during the postpartum period (558/100,000 person-years). CONCLUSION: Using combined CPRD and HES data gives estimates of the risk of VTE in and around pregnancy that are comparable to the existing literature. It also provides more accurate estimation of the date of VTE diagnosis which will allow risk stratification during specific pregnancy and postpartum periods.}, language = {eng}, number = {7}, journal = {PloS One}, author = {Abdul Sultan, Alyshah and Tata, Laila J. and Grainge, Matthew J. and West, Joe}, year = {2013}, pmid = {23922975}, pmcid = {PMC3726432}, keywords = {Adolescent, Adult, Cohort Studies, England, Female, Humans, Pregnancy Complications, Hematologic, Primary Health Care, Public Health Surveillance, Secondary Care, Venous Thromboembolism, Young Adult, incidence, pregnancy}, pages = {e70310} }

We hypothesized that Fontan failure is hemodynamically distinct from traditional heart failure and characterized by low systemic vascular resistance (SVR) index and preserved cardiac index. Twenty-seven symptomatic adult Fontan (SAF) patients who underwent catheterization from 2001 to 2011 constituted our study group. Fifty-four predominantly asymptomatic pediatric Fontan (PF) patients who underwent catheterization during the same period were randomly selected to perform a control:case cohort analysis. Clinical comparisons were made between the 2 groups. The adults were more symptomatic than the PF cohort (New York Heart Association classes I and II or III and IV: 48\% or 52\% [SAF] vs 94\% or 6\% [PF], respectively, p {\textless}0.01). SAF versus PF mean catheterization findings were central venous pressure 18 ± 6 versus 14 ± 3 mm Hg (p {\textless}0.01), SVR index 1,680 ± 368 versus 1,960 ± 550 dyn s/cm 5/m2 (p = 0.02), and cardiac index 2.7 ± 0.8 versus 2.8 ± 0.7 L/min/m2 (p = 0.25). By imaging, the SAF cohort demonstrated a greater incidence of abnormal liver texture changes (96\% vs 75\%, p = 0.04) and nodularity (77\% vs 42\%, p = 0.02). In conclusion, adult patients with failing Fontan circulation had a lower SVR index and similar cardiac index compared with the pediatric cohort. Liver disease in the adults was more advanced.

METHODS: Patients with a first diagnosis of post-herpetic neuralgia (PHN), painful diabetic neuropathy (PDN) or phantom limb pain (PLP) were identified from the General Practice Research Database (2006 - 2010) and incidence rates were calculated. Prescription records were searched for pain treatments from diagnosis of these conditions and the duration and daily dose estimated for first-line and subsequent treatment regimens. Recording of neuropathic back and post-operative pain was investigated. RESULTS: The study included 5,920 patients with PHN, 5,340 with PDN, and 185 with PLP. The incidence per 10,000 person-years was 3.4 (95\% CI 3.4, 3.5) for PHN; and 0.11 (95\% CI 0.09, 0.12) for PLP. Validation of the PDN case definition suggested that was not sensitive. Incident PHN increased over the study period. The most common first-line treatments were amitriptyline or gabapentin in the PDN and PLP cohorts, and amitriptyline or co-codamol (codeine-paracetamol) in PHN. Paracetamol, co-dydramol (paracetamol-dihydrocodeine) and capsaicin were also often prescribed in one or more condition. Most first-line treatments comprised only one therapeutic class. Use of antiepileptics licensed for neuropathic pain treatment had increased since 2002-2005. Amitriptyline was the only antidepressant prescribed commonly as a first-line treatment. CONCLUSION: The UK incidence of diagnosed PHN has increased with the incidence of back-pain and post-operative pain unclear. While use of licensed antiepileptics increased, prescribing of therapy with little evidence of efficacy in neuropathic pain is still common and consequently treatment was often not in-line with current guidance.}, language = {eng}, journal = {BMC family practice}, author = {Hall, Gillian C. and Morant, Steve V. and Carroll, Dawn and Gabriel, Zahava L. and McQuay, Henry J.}, year = {2013}, pmid = {23442783}, pmcid = {PMC3599764}, keywords = {Acetaminophen, Adolescent, Adult, Aged, Amines, Amitriptyline, Analgesics, Non-Narcotic, Analgesics, Opioid, Anticonvulsants, Capsaicin, Child, Child, Preschool, Codeine, Cyclohexanecarboxylic Acids, Diabetic Neuropathies, Drug Combinations, Drug Prescriptions, Female, Great Britain, Humans, Hydrocodone, Infant, Male, Middle Aged, Neuralgia, Postherpetic, Phantom Limb, Physician's Practice Patterns, Primary Health Care, Sensory System Agents, Young Adult, gamma-Aminobutyric Acid, incidence}, pages = {28} }

We determined whether a novel body shape measure, trunk to leg volume ratio, was independently associated with diabetes and mortality. METHODS: Data from the National Health and Nutritional Examination Survey 1999-2004, a study representative of the US population, were used to generate dual-energy X-ray absorptiometry-derived trunk to leg volume ratio and determine its associations to diabetes, metabolic covariates, and mortality by BMI category, gender, and race/ethnicity group. RESULTS: The prevalence of pre-diabetes and diabetes increased with age, BMI, triglycerides, blood pressure, and decreased HDL level. After adjusting for covariates, the corresponding fourth to first quartile trunk to leg volume ratio odds ratios (OR) were 6.8 (95\% confidence interval [CI], 4.9-9.6) for diabetes, 3.9 (95\% CI, 3.0-5.2) for high triglycerides, 1.8 (95\% CI, 1.6-2.1) for high blood pressure, 3.0 (95\% CI, 2.4-3.8) for low HDL, 3.6 (95\% CI, 2.8-4.7) for metabolic syndrome, and 1.76 (95\% CI, 1.20-2.60) for mortality. Additionally, trunk to leg volume ratio was the strongest independent measure associated with diabetes (P{\textless}0.001), even after adjusting for BMI and waist circumference. Even among those with normal BMI, those in the highest quartile of trunk to leg volume ratio had a higher likelihood of death (5.5\%) than those in the lowest quartile (0.2\%). Overall, trunk to leg volume ratio is driven by competing mechanisms of changing adiposity and lean mass. CONCLUSIONS: A high ratio of trunk to leg volume showed a strong association to diabetes and mortality that was independent of total and regional fat distributions.

Objects in familiar colors were detected efficiently at rates consistent with simultaneous binding across multiple stimuli. Processing limitations were evident for objects in unfamiliar colors. The advantage for the learned color for known targets was eliminated when participants searched for geometric shapes carrying the object colors and when the colors fell in local background areas around the shapes. The effect occurred irrespective of whether the nontargets had familiar colors, but was largest when nontargets had incorrect colors. The efficient search for targets in familiar colors held, even when the search was biased to favor objects in unfamiliar colors.

Rates of cancer diagnosed through unplanned admissions vary within and between countries, suggesting potential inconsistencies in the quality of care. To reduce diagnoses by this route and improve patient outcomes, high risk patient groups must be identified. This cross-sectional observational study determined the incidence of first-ever diagnoses of cancer by emergency (unplanned) admission and identified patient-level risk factors for these diagnoses in England. METHODS: Data for 74,763 randomly selected patients at 457 general practices between 1999 and 2008 were obtained from the General Practice Research Database (GPRD), including integrated Hospital Episode Statistics (HES) data and Office for National Statistics (ONS) mortality data. The proportion of first-ever diagnoses by emergency admission out of all recorded first cancer diagnoses by any route was analysed by patient characteristics. RESULTS: Diagnosis by emergency admission was recorded in 13.9\% of patients diagnosed with cancer for the first time (n = 817/5870). The incidence of first cases by the emergency route was 2.51 patients per 10,000 person years. In adjusted regression analyses, patients of older age (p {\textless} 0.0001), living in the most deprived areas (RR 1.93, 95\% CI 1.51 to 2.47; p {\textless} 0.0001) or who had a total Charlson score of 1 compared to 0 (RR 1.34, 95\% CI 1.06 to 1.69; p = 0.014) were most at risk of diagnosis by emergency admission. Patients with more prior (all-cause) emergency admissions were less at risk of subsequent diagnosis by the emergency route (RR 0.31 per prior emergency admission, 95\% CI 0.20 to 0.46; p {\textless} 0.0001). CONCLUSIONS: A much lower incidence of first-ever cancer diagnoses by emergency admission was found compared with previous studies.

The present study was designed to evaluate dislocation rates over time of interscalene and femoral nerve catheters under defined experimental circumstances. Ultrasound (US) monitoring was used to detect the position of the perineural catheters. METHODS: Twenty volunteers received US-guided interscalene and femoral nerve catheters. The volunteers performed standardized physical exercises in regular intervals and the position of both catheters was examined by US confirmation of the spread of fluid. The maximal time of investigation in each volunteer was 6 h. The main outcome parameters were the overall dislocation rates and the cumulative dislocation rates at a given time point. RESULTS: We observed an overall dislocation rate of 15\% (5\% for interscalene catheters, 25\% for femoral nerve catheters) and a significant correlation between time and rate of dislocations (r=0.99, P=0.001). US visualization of the spread of fluid was possible in all cases. CONCLUSIONS: This is the first dedicated evaluation of dislocation rates of peripheral nerve catheters (PNCs) via US investigation.

We compared lifestyle factors such as smoking and alcohol consumption between patients with rosacea and controls. METHODS: Using the U.K.-based General Practice Research Database, we identified patients with an incident diagnosis of rosacea between 1995 and 2009 and matched them (1:1) to rosacea-free control patients. We assessed person-time of all patients at risk and assessed incidence rates of rosacea, stratified by age, sex, year of diagnosis and region. RESULTS: We identified 60,042 rosacea cases and 60,042 controls (61·5\% women). The overall incidence rate for diagnosed rosacea in the U.K. was 1·65 per 1000 person-years. Rosacea was diagnosed in some 80\% of cases after the age of 30 years. Ocular symptoms were recorded in 20·8\% of cases at the index date. We observed a significantly reduced relative risk of developing rosacea among current smokers (odds ratio 0·64, 95\% confidence interval 0·62-0·67). Alcohol consumption was associated with a marginal risk increase. CONCLUSIONS: We quantified incidence rates and characteristics of patients with rosacea diagnosed in clinical practice in a large epidemiological study using primary care data from the U.K. Smoking was associated with a substantially reduced risk of developing rosacea.}, language = {eng}, number = {3}, journal = {The British Journal of Dermatology}, author = {Spoendlin, J. and Voegel, J.

AIM: Our aim was to determine the relative risk of type 2 diabetes, cancer, large-vessel disease (LVD), and all-cause mortality for women diagnosed with PCOS. DESIGN: Data were extracted from the General Practice Research Database, a longitudinal, anonymized research database derived from nearly 600 primary-care practices in the United Kingdom. Patients with a diagnosis of PCOS between 1990 and 2010 were selected. Patients were matched to two sets of controls. The first set was matched according to primary-care practice and age, and the second was also matched on body mass index. Primary outcome was first incident record of diabetes. Crude rates for diabetes were presented, and time to diabetes was analyzed using Cox proportional hazard models. Secondary outcomes (cancer, LVD, and mortality) were also modeled. RESULTS: Of 53,303 identified with a diagnosis of PCOS, 21,740 (40.8\%) met the eligibility criteria. Median follow-up was 4.7 yr (interquartile range = 2.0-8.6 yr) in those with PCOS and 5.8 yr (2.7-9.6) in the reference group. Crude rates of diabetes were 5.7 and 1.7 per 1000 patient-years for cases and controls, respectively. The corresponding adjusted hazard ratio was 3.015 (95\% confidence interval = 2.733-3.327). Of cases matched by body mass index, crude rates of diabetes were 4.7 and 2.4 per 1000 patient-years, respectively. The corresponding adjusted hazard ratio was 1.752 (1.514-2.028). No significant difference in BMI-adjusted risk was evident for cancer, LVD, or all-cause mortality.

OBJECTIVES: This study aims to quantify the risks associated with nonelective colorectal resection up to 1 year after surgery in elderly patients. DESIGN: This is a population-based observational study. SETTING: Data were obtained from the Hospital Episode Statistics database. POPULATION: All patients aged 70 years and older who underwent a nonelective colorectal resection in an English National Health Service Trust hospital between April 2001 and March 2008 were included. MAIN OUTCOME MEASURES: : The primary outcomes measured were 30-day in hospital mortality, 365-day mortality, unplanned readmission within 28 days of discharge, and duration of hospital stay. RESULTS: During the study period, 36,767 nonelective colorectal resections were performed in patients aged ≥ 70 years in England. Patients were classified into 3 age groups: A (70-75 years), B (76-80 years), and C (>80 years). Thirty-day mortality was 17.0%, 23.3%, and 31.0% in groups A, B, and C (p < 0.001). The overall 30-day medical complication rate was 33.7%, and the reoperation rate was 6.3%. Cardiac and respiratory complications were significantly higher in group C (22.2% and 18.2%, p < 0.001). Mortality in Group C was 51.2% at 1-year postsurgery. Advanced age was an independent determinant of mortality in risk-adjusted regression analyses. LIMITATIONS: This is a retrospective analysis of a prospective database. Stage of disease at presentation, severity of complications, and cause of death cannot be ascertained from this database. CONCLUSIONS: In this population-based study, half of all English patients aged over 80 years undergoing nonelective colorectal resection died within 1 year of surgery.

Methods: We searched Medline for randomised controlled trials assessing a relative reduction in influenza risk of all circulating influenza viruses during individual seasons after vaccination (efficacy) and observational studies meeting inclusion criteria (effectiveness). Eligible articles were published between Jan 1, 1967, and Feb 15, 2011, and used RT-PCR or culture for confirmation of influenza. We excluded some studies on the basis of study design and vaccine characteristics. We estimated random-effects pooled efficacy for trivalent inactivated vaccine (TIV) and live attenuated influenza vaccine (LAIV) when data were available for statistical analysis (eg, at least three studies that assessed comparable age groups). Findings: We screened 5707 articles and identified 31 eligible studies (17 randomised controlled trials and 14 observational studies). Efficacy of TIV was shown in eight (67%) of the 12 seasons analysed in ten randomised controlled trials (pooled efficacy 59% [95% CI 51-67] in adults aged 18-65 years). No such trials met inclusion criteria for children aged 2-17 years or adults aged 65 years or older. Efficacy of LAIV was shown in nine (75%) of the 12 seasons analysed in ten randomised controlled trials (pooled efficacy 83% [69-91]) in children aged 6 months to 7 years. No such trials met inclusion criteria for children aged 8-17 years. Vaccine effectiveness was variable for seasonal influenza: six (35%) of 17 analyses in nine studies showed significant protection against medically attended influenza in the outpatient or inpatient setting. Median monovalent pandemic H1N1 vaccine effectiveness in five observational studies was 69% (range 60-93). Interpretation: Influenza vaccines can provide moderate protection against virologically confirmed influenza, but such protection is greatly reduced or absent in some seasons. Evidence for protection in adults aged 65 years or older is lacking. LAIVs consistently show highest efficacy in young children (aged 6 months to 7 years). New vaccines with improved clinical efficacy and effectiveness are needed to further reduce influenza-related morbidity and mortality.

The Global Burden of Disease (GBD) studies done in 1990 and 2000 have been the only studies to quantify non-fatal health outcomes across an exhaustive set of disorders at the global and regional level. Neither effort quantified uncertainty in prevalence or years lived with disability (YLDs). METHODS: Of the 291 diseases and injuries in the GBD cause list, 289 cause disability. For 1160 sequelae of the 289 diseases and injuries, we undertook a systematic analysis of prevalence, incidence, remission, duration, and excess mortality. Sources included published studies, case notification, population-based cancer registries, other disease registries, antenatal clinic serosurveillance, hospital discharge data, ambulatory care data, household surveys, other surveys, and cohort studies. For most sequelae, we used a Bayesian meta-regression method, DisMod-MR, designed to address key limitations in descriptive epidemiological data, including missing data, inconsistency, and large methodological variation between data sources. For some disorders, we used natural history models, geospatial models, back-calculation models (models calculating incidence from population mortality rates and case fatality), or registration completeness models (models adjusting for incomplete registration with health-system access and other covariates). Disability weights for 220 unique health states were used to capture the severity of health loss. YLDs by cause at age, sex, country, and year levels were adjusted for comorbidity with simulation methods. We included uncertainty estimates at all stages of the analysis. FINDINGS: Global prevalence for all ages combined in 2010 across the 1160 sequelae ranged from fewer than one case per 1 million people to 350,000 cases per 1 million people. Prevalence and severity of health loss were weakly correlated (correlation coefficient -0·37). In 2010, there were 777 million YLDs from all causes, up from 583 million in 1990. The main contributors to global YLDs were mental and behavioural disorders, musculoskeletal disorders, and diabetes or endocrine diseases. The leading specific causes of YLDs were much the same in 2010 as they were in 1990: low back pain, major depressive disorder, iron-deficiency anaemia, neck pain, chronic obstructive pulmonary disease, anxiety disorders, migraine, diabetes, and falls. Age-specific prevalence of YLDs increased with age in all regions and has decreased slightly from 1990 to 2010. Regional patterns of the leading causes of YLDs were more similar compared with years of life lost due to premature mortality. Neglected tropical diseases, HIV/AIDS, tuberculosis, malaria, and anaemia were important causes of YLDs in sub-Saharan Africa. INTERPRETATION: Rates of YLDs per 100,000 people have remained largely constant over time but rise steadily with age. Population growth and ageing have increased YLD numbers and crude rates over the past two decades. Prevalences of the most common causes of YLDs, such as mental and behavioural disorders and musculoskeletal disorders, have not decreased. Health systems will need to address the needs of the rising numbers of individuals with a range of disorders that largely cause disability but not mortality. Quantification of the burden of non-fatal health outcomes will be crucial to understand how well health systems are responding to these challenges. Effective and affordable strategies to deal with this rising burden are an urgent priority for health systems in most parts of the world.

Research, using social care or government datasets, has identified a number of risk factors associated with children entering public care but the utility of risk factors in clinical practice is not established. This paper uses routine primary health care data to see if risk factors for children entering public care can be identified in clinical practice. METHODS: A nested case control methodology using routine primary care data from the United Kingdom. Health service use data were extracted for the 12 months before the case child entered public care and compared with 12 months of data for four control mother child pairs per case pair, matched on the age and sex of the child and the general practice. Exposures of interest were developed from a systematic review of the literature on risk factors associated with children entering public care. RESULTS: Conditional logistic regression was used to investigate the combined effect of more than one exposure of interest. Maternal mental illness (OR 2.51, 95\% CI 1.55-4.05), maternal age at birth of the child, socio-economic status (5(th) quintile vs. 1(st) quintile OR 7.14, 95\% CI 2.92-17.4), maternal drug use (OR 28.8, 95\% CI 2.29-363), non attendance at appointments (OR 2.42, 95\% CI 1.42-4.14), child mental illness (OR 2.65, 95\% CI 1.42-4.96) and child admission to hospital (OR 3.31, 95\% CI 1.21-9.02) were all significantly associated with children entering public care. Maternal use of primary care contraception services was negatively associated with children entering public care (OR 0.52, 95\% CI 0.31-0.87). CONCLUSIONS: Differences in health service use can be identified from routine primary care data in mother child pairs where children enter public care after controlling for maternal age and socio-economic status.

The following keywords were used: "accelerometry," "accelerometer," "physical activity," "PA," "patterns," "levels," "adults," "older adults," and "elderly," either alone or in combination using "AND" or "OR." The reference lists of the articles retrieved were examined to capture any other potentially relevant article. Of 899 studies initially identified, only 18 were fully reviewed, and their outcome measures abstracted and analyzed. RESULTS: Eleven studies were conducted in North America (United States), five in Europe, one in Africa (Cameroon) and one in Australia. Very few enrolled older people, and only one study reported the season or time of year when data was collected. The articles selected had different methods, analyses, and results, which prevented comparison between studies. CONCLUSIONS: There is a need to standardize study methods for data reporting to allow comparisons of results across studies and monitor changes in populations. These data can help design more adequate strategies for monitoring and promotion of physical activity.}, bibtype = {article}, author = {Bento, Teresa and Cortinhas, António and Leitão, José Carlos and Mota, Maria Paula}, journal = {Revista de saúde pública}, number = {3} }

The study included women with endometriosis, who had previously completed a 12-week, placebo-controlled study of dienogest, who participated in an open-label extension study for up to 53 weeks. Thereafter, a patient subgroup was evaluated in a 24-week follow-up after treatment discontinuation. METHODS: A multicenter study performed in Germany, Italy and Ukraine. Women with endometriosis were enrolled at completion of the placebo-controlled study (n = 168). All women received dienogest (2 mg once daily, orally) and changes in pelvic pain (on a visual analog scale), bleeding pattern, adverse events and laboratory parameters were evaluated during and after treatment. RESULTS: The completion rate among women who entered the open-label extension study was 90.5\% (n = 152). A significant decrease in pelvic pain was shown during continued dienogest treatment (P {\textless} 0.001). The mean frequency and intensity of bleeding progressively decreased. Adverse events, rated generally mild or moderate, led to withdrawal in four patients (2.4\%). No clinically relevant changes in laboratory parameters were observed. During treatment-free follow-up (n = 34), the reduction in pelvic pain persisted, while bleeding frequency and intensity returned to normal patterns. CONCLUSIONS: Long-term dienogest showed a favorable efficacy and safety profile, with progressive decreases in pain and bleeding irregularities during continued treatment; the decrease of pelvic pain persisted for at least 24 weeks after treatment cessation.}, language = {eng}, number = {1}, journal = {Archives of Gynecology and Obstetrics}, author = {Petraglia, Felice and Hornung, Daniela and Seitz, Christian and Faustmann, Thomas and Gerlinger, Christoph and Luisi, Stefano and Lazzeri, Lucia and Strowitzki, Thomas}, month = jan, year = {2012}, pmid = {21681516}, pmcid = {PMC3249203}, keywords = {Adolescent, Adult, Drug Administration Schedule, Endometriosis, Female, Follow-Up Studies, Germany, Hormone Antagonists, Humans, Italy, Middle Aged, Nandrolone, Pelvic Pain, Ukraine, Young Adult}, pages = {167--173} }

DESIGN: Cohort study of risk of cancer in people treated with angiotensin receptor blockers compared with angiotensin converting enzyme (ACE) inhibitors. Effects were explored with time updated covariates in Cox models adjusted for age, sex, body mass index (BMI), diabetes and metformin/insulin use, hypertension, heart failure, statin use, socioeconomic status, alcohol, smoking, and calendar year. Absolute changes in risk were predicted from a Poisson model incorporating the strongest determinants of risk from the main analysis. SETTING: UK primary care practices contributing to the General Practice Research Database. PARTICIPANTS: 377,649 new users of angiotensin receptor blockers or ACE inhibitors with at least one year of initial treatment. MAIN OUTCOME MEASURES: Adjusted hazard ratios for all cancer and major site specific cancers (breast, lung, colon, prostate) by exposure to angiotensin receptor blockers and by cumulative duration of use. RESULTS: Follow-up ended a median of 4.6 years after the start of treatment; 20,203 cancers were observed. There was no evidence of any increase in overall risk of cancer among those ever exposed to angiotensin receptor blockers (adjusted hazard ratio 1.03, 95\% confidence interval 0.99 to 1.06, P = 0.10). For specific cancers, there was some evidence of an increased risk of breast and prostate cancer (1.11, 1.01 to 1.21, P = 0.02; and 1.10, 1.00 to 1.20, P = 0.04; respectively), which in absolute terms corresponded to an estimated 0.5 and 1.1 extra cases, respectively, per 1000 person years of follow-up among those with the highest baseline risk. Longer duration of treatment did not seem to be associated with higher risk (P{\textgreater}0.15 in each case). There was a decreased risk of lung cancer (0.84, 0.75 to 0.94), but no effect on colon cancer (1.02, 0.91 to 1.16). CONCLUSIONS: Use of angiotensin receptor blockers was not associated with an increased risk of cancer overall. Observed increased risks for breast and prostate cancer were small in absolute terms, and the lack of association with duration of treatment meant that non-causal explanations could not be excluded.}, language = {eng}, journal = {BMJ (Clinical research ed.)}, author = {Bhaskaran, Krishnan and Douglas, Ian and Evans, Stephen and van Staa, Tjeerd and Smeeth, Liam}, year = {2012}, pmid = {22531797}, pmcid = {PMC3339864}, keywords = {Adolescent, Adult, Aged, Angiotensin Receptor Antagonists, Angiotensin-Converting Enzyme Inhibitors, Antihypertensive Agents, Breast Neoplasms, Causality, Cohort Studies, Data Interpretation, Statistical, Family Practice, Female, Great Britain, Humans, Hypertension, Male, Medical Records Systems, Computerized, Middle Aged, Neoplasms, Proportional Hazards Models, Prostatic Neoplasms, Risk Factors, Young Adult}, pages = {e2697} }

@article{kelly_london_2011, title = {The {London} low emission zone baseline study}, issn = {1041-5505}, abstract = {On February 4, 2008, the world's largest low emission zone (LEZ) was established. At 2644 km2, the zone encompasses most of Greater London. It restricts the entry of the oldest and most polluting diesel vehicles, including heavy-goods vehicles (haulage trucks), buses and coaches, larger vans, and minibuses. It does not apply to cars or motorcycles. The LEZ scheme will introduce increasingly stringent Euro emissions standards over time. The creation of this zone presented a unique opportunity to estimate the effects of a stepwise reduction in vehicle emissions on air quality and health. Before undertaking such an investigation, robust baseline data were gathered on air quality and the oxidative activity and metal content of particulate matter (PM) from air pollution monitors located in Greater London. In addition, methods were developed for using databases of electronic primary-care records in order to evaluate the zone's health effects. Our study began in 2007, using information about the planned restrictions in an agreed-upon LEZ scenario and year-on-year changes in the vehicle fleet in models to predict air pollution concentrations in London for the years 2005, 2008, and 2010. Based on this detailed emissions and air pollution modeling, the areas in London were then identified that were expected to show the greatest changes in air pollution concentrations and population exposures after the implementation of the LEZ. Using these predictions, the best placement of a pollution monitoring network was determined and the feasibility of evaluating the health effects using electronic primary-care records was assessed. To measure baseline pollutant concentrations before the implementation of the LEZ, a comprehensive monitoring network was established close to major roadways and intersections. Output-difference plots from statistical modeling for 2010 indicated seven key areas likely to experience the greatest change in concentrations of nitrogen dioxide (NO2) (at least 3 microg/m3) and of PM with an aerodynamic diameter {\textless} or = 10 microm (PM10) (at least 0.75 microg/m3) as a result of the LEZ; these suggested that the clearest signals of change were most likely to be measured near roadsides. The seven key areas were also likely to be of importance in carrying out a study to assess the health outcomes of an air quality intervention like the LEZ. Of the seven key areas, two already had monitoring sites with a full complement of equipment, four had monitoring sites that required upgrades of existing equipment, and one required a completely new installation. With the upgrades and new installations in place, fully ratified (verified) pollutant data (for PM10, PM with an aerodynamic diameter {\textless} or = 2.5 microm [PM2.5], nitrogen oxides [NOx], and ozone [O3] at all sites as well as for particle number, black smoke [BS], carbon monoxide [CO], and sulfur dioxide [SO2] at selected sites) were then collected for analysis. In addition, the seven key monitoring sites were supported by other sites in the London Air Quality Network (LAQN). From these, a robust set of baseline air quality data was produced. Data from automatic and manual traffic counters as well as automatic license-plate recognition cameras were used to compile detailed vehicle profiles. This enabled us to establish more precise associations between ambient pollutant concentrations and vehicle emissions. An additional goal of the study was to collect baseline PM data in order to test the hypothesis that changes in traffic densities and vehicle mixes caused by the LEZ would affect the oxidative potential and metal content of ambient PM10 and PM2.5. The resulting baseline PM data set was the first to describe, in detail, the oxidative potential and metal content of the PM10 and PM2.5 of a major city's airshed. PM in London has considerable oxidative potential; clear differences in this measure were found from site to site, with evidence that the oxidative potential of both PM10 and PM2.5 at roadside monitoring sites was higher than at urban background locations. In the PM10 samples this increased oxidative activity appeared to be associated with increased concentrations of copper (Cu), barium (Ba), and bathophenanthroline disulfonate-mobilized iron (BPS Fe) in the roadside samples. In the PM2.5 samples, no simple association could be seen, suggesting that other unmeasured components were driving the increased oxidative potential in this fraction of the roadside samples. These data suggest that two components were contributing to the oxidative potential of roadside PM, namely Cu and BPS Fe in the coarse fraction of PM (PM with an aerodynamic diameter of 2.5 microm to 10 microm; PM(2.5-10)) and an unidentified redox catalyst in PM2.5. The data derived for this baseline study confirmed key observations from a more limited spatial mapping exercise published in our earlier HEI report on the introduction of the London's Congestion Charging Scheme (CCS) in 2003 (Kelly et al. 2011a,b). In addition, the data set in the current report provided robust baseline information on the oxidative potential and metal content of PM found in the London airshed in the period before implementation of the LEZ; the finding that a proportion of the oxidative potential appears in the PM coarse mode and is apparently related to brake wear raises important issues regarding the nature of traffic management schemes. The final goal of this baseline study was to establish the feasibility, in ethical and operational terms, of using the U.K.'s electronic primary-care records to evaluate the effects of the LEZ on human health outcomes. Data on consultations and prescriptions were compiled from a pilot group of general practices (13 distributed across London, with 100,000 patients; 29 situated in the inner London Borough of Lambeth, with 200,000 patients). Ethics approvals were obtained to link individual primary-care records to modeled NOx concentrations by means of post-codes. (To preserve anonymity, the postcodes were removed before delivery to the research team.) A wide range of NOx exposures was found across London as well as within and between the practices examined. Although we observed little association between NOx exposure and smoking status, a positive relationship was found between exposure and increased socioeconomic deprivation. The health outcomes we chose to study were asthma, chronic obstructive pulmonary disease, wheeze, hay fever, upper and lower respiratory tract infections, ischemic heart disease, heart failure, and atrial fibrillation. These outcomes were measured as prevalence or incidence. Their distributions by age, sex, socioeconomic deprivation, ethnicity, and smoking were found to accord with those reported in the epidemiology literature. No cross-sectional positive associations were found between exposure to NOx and any of the studied health outcomes; some associations were significantly negative. After the pilot study, a suitable primary-care database of London patients was identified, the General Practice Research Database responsible for giving us access to these data agreed to collaborate in the evaluation of the LEZ, and an acceptable method of ensuring privacy of the records was agreed upon. The database included about 350,000 patients who had remained at the same address over the four-year period of the study. Power calculations for a controlled longitudinal analysis were then performed, indicating that for outcomes such as consultations for respiratory illnesses or prescriptions for asthma there was sufficient power to identify a 5\% to 10\% reduction in consultations for patients most exposed to the intervention compared with patients presumed to not be exposed to it. In conclusion, the work undertaken in this study provides a good foundation for future LEZ evaluations. Our extensive monitoring network, measuring a comprehensive set of pollutants (and a range of particle metrics), will continue to provide a valuable tool both for assessing the impact of LEZ regulations on air quality in London and for furthering understanding of the link between PM's composition and toxicity. Finally, we believe that in combination with our modeling of the predicted population-based changes in pollution exposure in London, the use of primary-care databases forms a sound basis and has sufficient statistical power for the evaluation of the potential impact of the LEZ on human health.}, language = {eng}, number = {163}, journal = {Research Report (Health Effects Institute)}, author = {Kelly, Frank and Armstrong, Ben and Atkinson, Richard and Anderson, H.

We aimed to quantify the association between having a spontaneous abortion and types and dosages of nonaspirin NSAIDs in a cohort of pregnant women. METHODS: Using a nested case-control design, we obtained data from the Quebec Pregnancy Registry for 4705 women who had a spontaneous abortion. For each instance, we randomly selected 10 controls from the remaining women in the registry who were matched by index date (date of the spontaneous abortion) and gestational age. Use of nonaspirin NSAIDs (identified by filled prescriptions) and nonuse were compared. We also looked for associations between different types and dosages of nonaspirin NSAIDs and having a spontaneous abortion. Analyses of associations and adjustment for confounding were done using conditional logistic regression. RESULTS: We identified 4705 cases of spontaneous abortion (352 exposed [7.5\%]); 47 050 controls (1213 exposed [2.6\%]). Adjusting for potential confounders, the use of nonaspirin NSAIDs during pregnancy was significantly associated with the risk of spontaneous abortion (odds ratio [OR] 2.43, 95\% confidence interval [CI] 2.12-2.79). Specifically, use of diclofenac (OR 3.09, 95\% CI 1.96-4.87), naproxen (OR 2.64, 95\% CI 2.13-3.28), celecoxib (OR 2.21, 95\% CI 1.42-3.45), ibuprofen (OR 2.19, 95\% CI 1.61-2.96) and rofecoxib (OR 1.83, 95\% CI 1.24-2.70) alone, and combinations thereof (OR 2.64, 95\% CI 1.59-4.39), were all associated with increased risk of spontaneous abortion.

There were 86 subjects in this analysis, and the most common indication for warfarin was prosthetic valve. Overall, the incidence of adverse bleeding events was 1.3\% per patient-year. An analysis of patient-related factors associated with a low percentage of time within goal range demonstrated that both female sex (P = 0.048) and nonwhite race (P = 0.037) were significantly associated with less time in the target range. Use of the software program was associated with an increase in the percentage of time during which the INR was within the target range from 41.4 to 53.1\% (P {\textless} 0.001). Incorporation of a computerized software program to assist dosing can improve the percentage of time that children with cardiac disease requiring warfarin remain within the target therapeutic range.

DESIGN: Retrospective prescription record review. DATA SOURCES: United Kingdom General Practice Research Database, and the MarketScan Commercial Claims and Encounters Database for U.S. data. SUBJECTS: In the U.K. database, we identified 1.6 million people younger than 65 years who were prescribed at least one prescription drug in at least one of the calendar years during the study period (2004-2006). For comparison, for each U.K. person identified, we randomly identified one person of the same sex and year of birth in the U.S. database who was also prescribed at least one drug in the same calendar year. MEASUREMENTS AND MAIN RESULTS: We compared the frequency of prescribing of individual drugs, as well as selected therapeutic categories. Substantially higher proportions of people in the United States were prescribed antibiotics, statins, and postmenopausal hormones, but asthma drugs were prescribed more frequently in the United Kingdom. In those younger than 20 years, antidepressants and antipsychotics were prescribed more than twice as frequently in the United States, and males in the United States were far more likely to be prescribed drugs for attention-deficit-hyperactivity disorder than were their counterparts in the United Kingdom. CONCLUSION: This study provides documented quantification of differing patterns of drug use in the United States and United Kingdom during 2004-2006. The higher proportionate prescribing for most indications in the United States and the greater use of drugs under patent suggest that monetary costs are likely to be considerably higher in the United States than in the United Kingdom.}, language = {eng}, number = {7}, journal = {Pharmacotherapy}, author = {Parkin, Lianne and Hagberg, Katrina Wilcox and Jick, Hershel}, month = jul, year = {2011}, pmid = {21923448}, keywords = {Adolescent, Adult, Age Factors, Child, Databases, Factual, Female, Great Britain, Humans, Male, Middle Aged, Physician's Practice Patterns, Prescription Drugs, Retrospective Studies, Sex Factors, United States, Young Adult}, pages = {623--629} }

The purpose of this study was to determine cadence patterns in free-living adults, and in particular, time spent at increasing cadence increments including 100 steps/min and beyond. METHOD: 3744 adults ≥20 years provided at least one valid day (minimally 10/24 h of wear) of minute-by-minute accelerometer-determined step data during the 2005-2006 U.S. National Health and Nutrition Examination Survey (NHANES).

National pharmacovigilance centres have been receiving reports from healthcare professionals and patients of uterine perforation associated with the use of these LNG-IUDs. METHODS: National pharmacovigilance centres in the Netherlands, New Zealand, Switzerland and Germany did a search on their adverse drug reaction databases for reports of cases of uterine perforation after insertion of a LNG-IUD received between the introduction of the LNG-IUD onto the market in the late 1990s and 15 July 2007. The number of women affected and patient characteristics such as age, parity and breastfeeding status were examined. In addition, the method of detection of the perforation and the time until discovery of the perforation were analysed. RESULTS: Between the introduction of the LNG-IUD onto the market in each country and 15 July 2007, 701 cases of uterine perforation with a LNG-IUD were reported; 8.5\% of the perforations were detected at the time of insertion. Abdominal pain and control/check-up visits were the most common events that lead to the detection of a perforation. Of 462 women known to be parous, 192 (42\%) were breastfeeding at the time the perforation was discovered. CONCLUSIONS: Uterine perforations can be asymptomatic and may remain undetected for a long time after IUD insertion. Abdominal pain, control/check-up visits or changes in bleeding patterns are triggers for detection of perforation and should therefore be taken seriously.}, language = {eng}, number = {1}, journal = {Drug Safety}, author = {van Grootheest, Kees and Sachs, Bernhardt and Harrison-Woolrych, Mira and Caduff-Janosa, Pia and van Puijenbroek, Eugène}, month = jan, year = {2011}, pmid = {21142273}, keywords = {Abdominal Pain, Adolescent, Adult, Adverse Drug Reaction Reporting Systems, Breast Feeding, Contraceptive Agents, Female, Databases, Factual, Female, Foreign-Body Migration, Humans, Intrauterine Devices, Medicated, Levonorgestrel, Middle Aged, Retrospective Studies, Time Factors, Uterine Perforation, Young Adult}, pages = {83--88} }

METHODS: We used data from the General Practice Research Database, which contains the computerized records of 6.25 million patients and is representative of the population of the UK. We identified all subjects with a new diagnosis of WG in the period 1989-2004, and for each case, compared mortality with 10 controls matched for age, gender and practice. RESULTS: We identified 255 patients with a new diagnosis of WG (mean age 58.1 years, range 9-90 years, 47\% females) and 2546 controls (mean age 58.1 years, range 9-89 years, 47\% females). Mean follow-up was 6.4 years. The mortality for patients with WG was significantly increased during the first year after diagnosis [HR 9.0 (95\% CI 5.8, 13.9)], especially for those ≤ 65 years of age [HR 19.9 (95\% CI 8.8, 44.9)]. The excess mortality was less marked after the first year: 1-5 years [HR 1.68 (95\% CI 1.08, 2.60)], 5-10 years [HR 2.41 (95\% CI 1.43, 4.07)], but started to increase by 10-15 years [HR 4.4 (95\% CI 2.0, 9.8)]. The Kaplan-Meier survival curve showed an increase in mortality after 8 years. CONCLUSIONS: Despite current therapy, patients with WG have a 9-fold increased risk of death in the first year of disease, attributed to infection, active vasculitis and renal failure. Between 1 and 8 years the risk is at its lowest, although higher than the control population.

Oscillation analyses conducted on the Think/No-Think (TNT) task and volitional suppression of retrieval are of interest to broaden our knowledge of neural oscillations associated not only during successful memory retrieval but also when retrieval is unwanted or suppressed. In the current study, we measured EEG during a TNT task and performed ERP and EEG spectral power band analyses. ERP results replicated other researchers' observations of increases in 500-800 msec parietal effects for items where retrieval was instructed to be elaborated compared with being suppressed. Furthermore, EEG analyses indicated increased alpha (8-12 Hz) and theta (3-8 Hz) oscillations across parietal electrodes for items that were instructed to be suppressed versus those to be elaborated. Additionally, during the second half of the experiment (after repeated attempts at control), increases in theta oscillations were found across both frontal and parietal electrodes for items that were instructed to be suppressed and that were ultimately forgotten versus those ultimately remembered. Increased alpha power for items that were instructed to be suppressed versus elaborated may indicate reductions of retrieval attempts or lack of retrieval success. Increased theta power for items that were instructed to be suppressed versus elaborated may indicate increased or prolonged cognitive control to monitor retrieval events.}, bibtype = {article}, author = {Depue, Brendan Eliot and Ketz, Nick and Mollison, Matthew V and Nyhus, Erika and Banich, Marie T and Curran, Tim}, journal = {Journal of Cognitive Neuroscience}, number = {10} }

We sought to evaluate short- and midterm results of intravascular thoracic vessel stent placement for patients with fibrosing mediastinitis. DESIGN: We reviewed all records of fibrosing mediastinitis patients who were referred for stent placement to treat mediastinal vascular compression over a 7-year period. Catheterization reports and digital angiography were assessed to determine vessel dimension and stent characteristics. PATIENTS: Thirteen catheterizations were performed in six patients (five females, mean age 39 years, range 23-63) with a range of 1-4 per patient. INTERVENTIONS: Four patients were treated with intravascular stents placed percutaneously. One patient underwent surgical intravascular stent placement, and one patient declined surgical therapy. The right pulmonary artery was treated in three patients, the superior vena cava was treated in one patient, and three pulmonary veins were treated in one patient. OUTCOME MEASURES: Pertinent vessel and hemodynamics including immediate short-, and mid-term results were assessed. Procedural complications, midterm follow-up (up to 7 years), and overall survival were determined. RESULTS: Each intervention resulted in hemodynamic improvement with subsequent clinical improvement. Reintervention was required within 12 months in two of four percutaneously treated patients. One death occurred 4 days after cutting balloon angioplasty in a preexisting pulmonary vein stent. CONCLUSIONS: Percutaneous therapy for vessel compression secondary to fibrosing mediastinitis is an option that is effective in improving short-term vascular patency. In-stent stenosis was a frequent complication in patients with fibrosing mediastinitis, particularly when pulmonary veins were involved. Short- and midterm success can be achieved, but progressive fibrosing mediastinitis remains a difficult clinical problem with repeat dilation of stents and/or additional stent placement necessary to maintain optimal stent patency and improvement in clinical symptomatology.}, language = {eng}, number = {2}, journal = {Congenit Heart Dis}, author = {Ferguson, ME and Cabalka, AK and Cetta, F and Hagler, DJ}, month = mar, year = {2010}, keywords = {Young Adult}, pages = {124--133} }

DESIGN: Prospective cohort study. Setting UK General Practice Research Database. PARTICIPANTS: Primary care patients with a diagnosis of substance misuse prescribed methadone or buprenorphine during 1990-2005. 5577 patients with 267 003 prescriptions for opiate substitution treatment followed-up (17 732 years) until one year after the expiry of their last prescription, the date of death before this time had elapsed, or the date of transfer away from the practice. MAIN OUTCOME MEASURES: Mortality rates and rate ratios comparing periods in and out of treatment adjusted for sex, age, calendar year, and comorbidity; standardised mortality ratios comparing opiate users' mortality with general population mortality rates. RESULTS: Crude mortality rates were 0.7 per 100 person years on opiate substitution treatment and 1.3 per 100 person years off treatment; standardised mortality ratios were 5.3 (95\% confidence interval 4.0 to 6.8) on treatment and 10.9 (9.0 to 13.1) off treatment. Men using opiates had approximately twice the risk of death of women (morality rate ratio 2.0, 1.4 to 2.9). In the first two weeks of opiate substitution treatment the crude mortality rate was 1.7 per 100 person years: 3.1 (1.5 to 6.6) times higher (after adjustment for sex, age group, calendar period, and comorbidity) than the rate during the rest of time on treatment. The crude mortality rate was 4.8 per 100 person years in weeks 1-2 after treatment stopped, 4.3 in weeks 3-4, and 0.95 during the rest of time off treatment: 9 (5.4 to 14.9), 8 (4.7 to 13.7), and 1.9 (1.3 to 2.8) times higher than the baseline risk of mortality during treatment. Opiate substitution treatment has a greater than 85\% chance of reducing overall mortality among opiate users if the average duration approaches or exceeds 12 months.

This cytokine is produced by activated T helper 1 cells, which can best deal with intracellular pathogens such as M. tuberculosis. Based on the hypothesis that genes which regulate interferon gamma may influence tuberculosis susceptibility, we investigated polymorphisms in eight candidate genes. METHODS: Fifty-four polymorphisms in eight candidate genes were genotyped in over 800 tuberculosis cases and healthy controls in a population-based case-control association study in a South African population. Genotyping methods used included the SNPlex Genotyping System, capillary electrophoresis of fluorescently labelled PCR products, TaqMan SNP genotyping assays or the amplification mutation refraction system. Single polymorphisms as well as haplotypes of the variants were tested for association with TB using statistical analyses. RESULTS: A haplotype in interleukin 12B was nominally associated with tuberculosis (p = 0.02), but after permutation testing, done to assess the significance for the entire analysis, this was not globally significant. In addition a novel allele was found for the interleukin 12B D5S2941 microsatellite.

The instrument is based on diffuse correlation spectroscopy (DCS) for measurement of cerebral blood flow (CBF), and near-infrared spectroscopy (NIRS) for measurement of oxy- and deoxy-hemoglobin concentration. DCS/NIRS measurements of CBF and oxygenation from frontal lobes are compared with concurrent xenon-enhanced computed tomography (XeCT) in patients during induced blood pressure changes and carbon dioxide arterial partial pressure variation. METHODS: Seven neurocritical care patients were included in the study. Relative CBF measured by DCS (rCBF(DCS)), and changes in oxy-hemoglobin (DeltaHbO(2)), deoxy-hemoglobin (DeltaHb), and total hemoglobin concentration (DeltaTHC), measured by NIRS, were continuously monitored throughout XeCT during a baseline scan and a scan after intervention. CBF from XeCT regions-of-interest (ROIs) under the optical probes were used to calculate relative XeCT CBF (rCBF(XeCT)) and were then compared to rCBF(DCS). Spearman's rank coefficients were employed to test for associations between rCBF(DCS) and rCBF(XeCT), as well as between rCBF from both modalities and NIRS parameters. RESULTS: rCBF(DCS) and rCBF(XeCT) showed good correlation (r (s) = 0.73, P = 0.010) across the patient cohort. Moderate correlations between rCBF(DCS) and DeltaHbO(2)/DeltaTHC were also observed. Both NIRS and DCS distinguished the effects of xenon inhalation on CBF, which varied among the patients.

However, little has been documented in terms of Muslim patients and medical students in the clinical consultation. {METHODS}: Female Emirati nationals (n = 218) attending out-patient clinics at a public hospital in Al Ain, United Arab Emirates ({UAE}), were interviewed by medical students. Participants were provided with four hypothetical clinical scenarios (three personal, one concerning a pre-pubertal child) and asked whether they would allow male and female students to be present at a consultation, take a history or perform an examination. They were also canvassed about their past experiences with medical students and their social responsibility to contribute towards the training of Emirati doctors. {RESULTS}: Significant differences were recorded in terms of female versus male student involvement for all activities (P {\textless} 0.05-0.0005). For gynaecological and abdominal problems, patients would generally refuse male students. More than 50% of interviewees would not allow a male student to examine their face. Students of either gender could, however, examine their 8-year-old child. Although 47% of the women had had previous clinical encounters with students, in only 58% of consultations had the attending doctor asked their permission. Despite this, the women had generally felt comfortable, although satisfaction decreased with increasing age (P = 0.088). Almost 90% of the women believed that Emiratis had a social responsibility to contribute towards the training of Emirati doctors, but this decreased with increasing income (P = 0.004). {CONCLUSIONS}: As many medical students will encounter Muslim patients during their training, they need to be sensitive to religious and cultural issues, particularly for personal examinations. In contexts where most patients are Muslim, alternative options (e.g. manikins, international rotations) may be required for male students.

During forward egomotion, the distant road edges provided future path information, which participants used to improve their heading judgments. During backward egomotion, the road edges did not enhance performance because they no longer provided prospective information.

DESIGN: Comparative cohort study of patients with endometriosis treated consecutively between July 2003 and January 2009 with a follow-up between six months and six years. SETTING: Braemar Hospital, Hamilton, New Zealand. RESULTS: We treated 20 adolescents. Ninety-five per cent (19/20) of adolescents were using pain relief other than Paracetamol, in contrast to only 59\% (84/143) of non-adolescents. Thirty per cent (6/20) of adolescents had a first-degree relative with endometriosis, in contrast to 8\% (11/143) of non-adolescents. Endometriosis was found to be stage I in 40\% (8/20) of patients, stage II in 45\% (9/20) of patients, stage III in 5\% (1/20) of patients and stage IV in 10\% (2/20) of patients. The main type of endometriotic lesion in the adolescent was an atypical red vascular lesion, which was present in 60\% (12/20) of adolescents; but it was present in only 20\% (29/143) of non-adolescents. There were no intra-operative complications. Minor postoperative complications included one case of urinary tract infection and one case of port infection. The operative complications that developed when treating the non-adolescent group are presented for comparison. Pain scores recorded at follow-up revealed a significant reduction in dysmenorrhoea and pelvic pain and there was a positive effect on the quality of life of adolescents as measured by the EQ-5D questionnaire tool. CONCLUSION: Adolescents with endometriosis use significantly more pain relief than non-adolescents to control symptoms. They have a higher rate of a first degree relative with the disease and they present with more atypical endometriotic lesions when compared with an adult population with endometriosis. All the stages of disease are present in the adolescent, including stages III and IV.

METHODS: Data for this retrospective cohort study were extracted from the GPRD, a large primary care database in the UK. Data from adults with an incident prescription of escitalopram, venlafaxine, or generic SSRI were extracted. The initial prescription had to fall within 3 months of a physician visit when severe depression according to the GPRD definition was mentioned. Frequency of antidepressant treatment, GP consultations, referrals, hospitalisations, and concomitant psychiatric medication was assessed on the 12-months after initial prescription and 2006 unit costs for healthcare services obtained from published literature were applied, and then compared between treatment cohorts using a propensity score-adjusted generalised linear model. RESULTS: The total annual healthcare expenditure per patient was similar with escitalopram and generic SSRIs (916 pounds vs. 974 pounds, adjusted p = 0.48) and significantly lower than venlafaxine (916 pounds vs. 1367 pounds, adjusted p {\textless} 0.0001), a pattern repeated when antidepressant costs were excluded from the analysis (escitalopram vs. SSRIs, 831 pounds vs. 957 pounds, adjusted p = 0.10; escitalopram vs. venlafaxine, 831 pounds vs. 1156 pounds, adjusted p = 0.006). Over the 12-month analysis period, there were significantly fewer hospitalisations per patient in the escitalopram vs. venlafaxine (0.12 vs. 0.27; adjusted p = 0.01) or generic SSRI (0.12 vs. 0.19; adjusted p = 0.046) groups. CONCLUSION: Despite some limitations associated with the system of data collection in the GPRD (need to apply proxies for severity assessment and external unit costs to resource consumption), the results of this real-life study brings additional evidence of escitalopram appearing to be a cost-effective treatment for patients suffering from severe depression as diagnosed in routine practice and could be considered for first-line treatment in these patients.}, language = {eng}, number = {5}, journal = {Current Medical Research and Opinion}, author = {Wade, Alan G. and Saragoussi, Delphine and Despiégel, Nicolas and François, Clément and Guelfucci, Florent and Toumi, Mondher}, month = may, year = {2010}, pmid = {20297951}, keywords = {Adolescent, Adult, Aged, Citalopram, Cyclohexanols, Drugs, Generic, Female, Great Britain, Health Care Costs, Humans, Male, Middle Aged, Retrospective Studies, Serotonin Uptake Inhibitors, Severity of Illness Index, Young Adult, depression}, pages = {1161--1170} }

In some instances movements can be recorded through a simple button press on a computer input device. In other situations responses can be captured through questionnaire surveys. Nevertheless, there is a need within many neuroscience settings to capture how complex movements unfold over time (human kinematics). Current methods of measuring human kinematics range from accurate but multifarious laboratory configurations to portable but simplistic and time-consuming paper and pen methods. We describe a new system for recording the end-point of human movement that has the power of laboratory measures but the advantages of pen-and-paper tests: the Kinematic Assessment Tool. KAT provides a highly portable system capable of measuring human movement in configurable visual-spatial tasks. The usefulness of the system is shown in a study where 12 participants undertook a tracing and copying task using their preferred and non-preferred hand. The results show that it is possible to capture behaviour within complex tasks and quantify performance using objective measures automatically generated by the KAT system. The utility of these measures was indexed by our ability to distinguish the performance of the preferred and non-preferred hand using a single variable.}, bibtype = {article}, author = {Culmer, Peter R and Levesley, Martin C and Mon-Williams, Mark and Williams, Justin H G}, journal = {Journal of neuroscience methods}, number = {1} }

Optimality models show that controlling a redundant musculo-skeletal system in this manner meets task demands while minimizing control effort. Although this line of inquiry has been very productive, the data are mostly behavioral with no direct physiological evidence on the level of muscle or neural activity. Furthermore, biomechanical coupling, signal-dependent noise, and alternative causes of trial-to-trial variability confound behavioral studies. Here we address those confounds and present evidence that the nervous system preferentially controls task-relevant parameters on the muscle level. We asked subjects to produce vertical fingertip force vectors of prescribed constant or time-varying magnitudes while maintaining a constant finger posture. We recorded intramuscular electromyograms (EMGs) simultaneously from all seven index finger muscles during this task. The experiment design and selective fine-wire muscle recordings allowed us to account for a median of 91% of the variance of fingertip forces given the EMG signals. By analyzing muscle coordination in the seven-dimensional EMG signal space, we find that variance-per-dimension is consistently smaller in the task-relevant subspace than in the task-irrelevant subspace. This first direct physiological evidence on the muscle level for preferential control of task-relevant parameters strongly suggest the use of a neural control strategy compatible with the principle of minimal intervention. Additionally, variance is nonnegligible in all seven dimensions, which is at odds with the view that muscle activation patterns are composed from a small number of synergies.}, keywords = {Adolescent, Adult, Biological, Biomechanics, Electromyography, Female, Fingers, Humans, Male, Models, Movement, Muscle, Muscle Contraction, Muscle Strength, Posture, Principal Component Analysis, Psychomotor Performance, Skeletal, Time Factors, Young Adult}, issn = {0022-3077}, doi = {10.1152/jn.90324.2008}, url = {http://jn.physiology.org/content/102/1/59.long}, author = {Valero-Cuevas, Francisco J and Venkadesan, Madhusudhan and Todorov, Emanuel} }

DESIGN: Nested case-control study. SETTING: Database study using the General Practice Research Database for the years 1992-1998. POPULATION: Women aged 15-49 years with a diagnosis of menorrhagia. METHODS: Multivariate conditional logistic regression was used to estimate the risk for VTE associated with different drug treatments for menorrhagia, adjusting for confounders. MAIN OUTCOME MEASURES: Adjusted odds ratios with 95\% CI. RESULTS: A total of 134 cases of VTE and 552 matched controls were identified. Recent use of tranexamic acid was scarce, yielding an adjusted odds ratio for VTE of 3.20 (95\% CI 0.65-15.78). The use of mefenamic acid (ORadj 5.54 [95\% CI 2.13-14.40]) or norethisterone (ORadj 2.41 [95\% CI 1.00-5.78]) was associated with an increased risk of VTE, as was a recent--in relation to menorrhagia--diagnosis of anaemia or a haemoglobin value {\textless}11.5 g/dl (ORadj 2.23 [95\% CI 1.02-4.86]). CONCLUSIONS: We found that tranexamic acid was associated with an increased risk of VTE, although the risk estimate did not reach statistical significance. Increased risks of VTE associated with other treatments for menorrhagia were observed. The increased risk of VTE observed with a diagnosis of anaemia--a proxy for more severe menorrhagia--suggests that menorrhagia could be a prothrombotic condition. The observed association between VTE, tranexamic acid and other treatments for menorrhagia may thus partly be explained by confounding by indication.

The origin and spread was mapped in 350 general practices that used office computers to contribute comprehensive medical information on approximately 3 million patients to the General Practice Research Database (GPRD). METHODS: The continuous 3-month cumulative incidence of mumps (2003-2006) was estimated by dividing the number of diagnosed cases of mumps each 3 months by the population at risk according to age, region, practice, and calendar time. The effect of the measles, mumps, and rubella (MMR) vaccine was estimated by comparing vaccine exposure of those diagnosed with mumps and those who were not. RESULTS: There were 5683 cases of mumps recorded in the Database over the 4-year time period. As the Database represents about 5\% of the UK population, we estimate that there were more than 100,000 cases of mumps diagnosed in the UK during these 4 years. The epidemic appears to have started in one practice in Wales in the first 6 months of 2003 and then spread slowly north and east, reaching a peak in 2005. Young adults aged 18-24 years were at the highest risk. There were 3 major MMR vaccination campaigns (1988-1989, 1997, and 2004-2005) that by 2006 provided more than 70\% protection against mumps in children younger than 18 years of age. Protection was higher in those who had received 2 doses of the vaccine.

METHOD: The UK General Practice Research Database (GPRD) was used to identify patients aged 2-21 years from 1 January 1993 to 30 June 2006 with a prescription for methylphenidate, dexamfetamine or atomoxetine. Patients were followed from the date of first prescription until whichever came first: date of death, transferred-out date, age {\textgreater}21 years or end of the study period. RESULTS: From a cohort of 18 637 patient-years, seven patients died. Cause of death was obtained for six of the patients. None were deemed to be cases of sudden death. Compared with a general population rate of sudden death in the literature, the worst-case scenario of one case of sudden death gave an incident rate ratio of 1.63 (95\% CI 0.04, 9.71). Although it was not the primary outcome of the study, following reports of suicide in the cohort the standardized mortality ratio (SMR) of suicide was calculated. Due to differences in the definition of suicide used for children and adults, patients were categorized into two age groups: 11-14 years and 15-21 years. The SMR for suicide for patients aged 11-14 years was 161.91 (95\% CI 19.61, 584.88). The SMR for suicide for patients aged 15-21 years was 1.84 (95\% CI 0.05, 10.25). CONCLUSION: This study demonstrated no increase in the risk of sudden death associated with stimulants or atomoxetine. However, an increased risk of suicide was seen. Although we cannot exclude that the medications may contribute to the increased risk of suicide, there are other factors such as depression and antisocial behaviour that frequently co-exist with ADHD, which can also predispose to teenage suicide.

Fifty-six patients with MSICTs underwent microsurgery for tumor removal using a posterior approach. The tumor was exposed through a dorsal myelotomy. Pre-operative and post-operative nervous function was scored using the Improved Japanese Orthopaedic Association (IJOA) grading system. Correlation analyses were performed between functional outcome (IJOA score) and histological features, age, tumor location, and the longitudinal extent of spinal cord involvement. The most frequently involved levels were the medullo cervical and the cervicothoracic regions (51.8%, 29/56) followed by the conus terminalis (26.8%, 15/56) and the thoracic region (14.3%, 8/56). Ependymoma was the most frequent MSICT type, seen in 22 of 56 patients (39%), followed by low grade astrocytoma (17 patients, 30%) and glioblastoma multiforme (3 patients, 5%). Gross total tumor removal was achieved in 33 cases (58%), subtotal resection in 4 (7%), and partial resection in 16 (28%). The histological classification of the tumor was the most important factor influencing the extent of surgical removal (chi2=22.17, p=0.00). The overall difference between pre-operative and post-operative neurological state was not significant (chi2=5.44, p=0.61). Thus, MSICTs were most commonly seen in the medullo cervical and cervicothoracic regions, with ependymoma and low grade astrocytoma the most common tumour types. We stress the importance of early microsurgical treatment for MSICTs while the patients do not have severe dysfunction.}, bibtype = {article}, author = {Sun, Jianjun and Wang, Zhenyu and Li, Zhendong and Liu, Bin}, journal = {Journal of clinical neuroscience : official journal of the Neurosurgical Society of Australasia}, number = {5} }

In this study, we investigated whether this model can be extended to bipolar disorder by testing the hypothesis that neurocognitive functioning is inversely related to positive psychotic symptoms in bipolar disorder. METHODS: Neurocognitive functioning and psychopathology were assessed in (i) 76 patients with bipolar disorder, (ii) 39 of their healthy first-degree relatives, and (iii) 61 healthy controls. Cognitive performance of bipolar patients and their first-degree relatives was investigated, taking into account the possible moderating effect of the level of expression of psychosis in patients and relatives. RESULTS: Bipolar patients showed impaired cognitive performance on multiple cognitive domains, whereas performance of their relatives was comparable to that of controls. A history of psychotic symptoms in patients was suggestive of less likelihood of cognitive alterations in relatives, and the presence of subclinical psychotic symptoms within the group of relatives predicted better cognitive performance. CONCLUSIONS: The finding of similar psychosis-cognition associations in bipolar disorder as implied by the two pathways leading to nonaffective psychotic disorders suggests that this model might be extended to the continuum spanning affective and nonaffective psychosis. This is in line with the idea of a partially overlapping vulnerability to bipolar disorder and schizophrenia and provides an explanation for the apparent differences in cognitive alterations in those at risk for the two disorders.}, language = {eng}, number = {2}, journal = {Bipolar Disorders}, author = {Jabben, Nienke and Arts, Baer and Krabbendam, Lydia and van Os, Jim}, month = mar, year = {2009}, pmid = {19267699}, note = {00041 }, keywords = {Adolescent, Adult, Association, Attention, Bipolar Disorder, Cognition Disorders, Female, Humans, Male, Memory, Middle Aged, Neuropsychological Tests, Principal Component Analysis, Psychiatric Status Rating Scales, Psychotic Disorders, Reaction Time, Schizophrenia, Schizophrenic Psychology, Young Adult}, pages = {166--177} }

Different clinical subtypes may be characterized by differing pathophysiological mechanisms and treatment outcomes. METHODS: A cluster analysis was performed on 45 items of the Yale-Brown Obsessive-Compulsive Symptoms Checklist (YBOCS-CL) for 261 patients with OCD. Cluster solutions emerging at different linkage distance levels, and the associations of identified clusters with demographic, clinical and relevant genetic variables, were investigated. RESULTS: A 6-cluster solution emerged at a linkage distance level of 1.5, and a 3-cluster solution emerged at a linkage distance level of 2.1. The 3 clusters in the latter solution were labeled I) Contamination / washing, II) Hoarding / symmetry / ordering, and III) Obsessional / checking. Increased Cluster III scores were associated with earlier age of OCD onset and the Met/Met (L/L) genotype of the COMT Val158Met polymorphism. CONCLUSION: The data here are consistent with previous work delineating the different symptom subtypes of OCD, also with previous work suggesting that the Met/Met (L/L) genotype of the COMT Val158Met polymorphism may be associated with anxiety symptoms, as well as with previous work suggesting that dopaminergic genes may be particularly important in early-onset OCD.}, language = {eng}, number = {3}, journal = {The Israel Journal of Psychiatry and Related Sciences}, author = {Lochner, Christine and Hemmings, Sian M.

Studies in single sensory modalities show that object recognition is facilitated if bottom-up inputs match a template held in {WM}, and that this effect may be linked to enhanced synchronization of neurons in the gamma-band ({\textgreater}30 Hz). Natural objects, however, frequently provide inputs to multiple sensory modalities. In this {EEG} study, we examined the integration of semantically matching or non-matching visual and auditory inputs using a delayed visual-to-auditory object-matching paradigm. In the event-related potentials ({ERPs}) triggered by auditory inputs, effects of semantic matching were observed after 120-170 ms at frontal and posterior regions, indicating {WM}-specific processing across modalities, and after 250-400 ms over medial-central regions, possibly reflecting the contextual integration of sensory inputs. Additionally, total gamma-band activity ({GBA}) with medial-central topography after 120-180 ms was larger for matching compared to non-matching trials.

However, there is a paucity of epidemiological data from the general population. Our aim was to estimate the annual person-level incidence for a wide spectrum of clinically diagnosed soft tissue knee injuries, and their distribution by age, sex, and season. {METHODS}: In Sweden, in- and outpatient health care is registered using each individuals' unique personal identifier including International Classification of Diseases ({ICD}) 10 diagnostic code(s) as determined by physicians' clinical examination. For the calendar years 2004-2012, we studied the population in southern Sweden, Skane region (approx. 1.3 million). We identified residents who had at least one visit to a physician with clinically diagnosed knee ligament, meniscal, or other soft-tissue injury (S80.0, S83 and all subdiagnoses). We then calculated the mean annual incidence over the 9-year period. As a secondary objective, we investigated potential seasonal variation. {RESULTS}: The annual incidence for males and females was 766 (95\% {CI}: 742, 789) and 676 (649, 702) per 100,000 persons/year respectively. For males and females, the peak rate occurred in 15 to 19 year-olds (1698 per 100,000 men and 1464 per 100,000 women, respectively). In women, rates were lowest in the 25 to 34 year-old age range before rising again between the ages of 35 and 49 years. We found substantial seasonal variation, greatest in men, with peaks in March-May and August-October. {CONCLUSIONS}: The incidence of clinically diagnosed soft-tissue knee injury peaks in adolescence and emerging adulthood.
