Masculine Gender Role Stress
2003
Eisler and Blalock (Clin. Psychol. Rev. 11 (1991) 45) developed a cognitively mediated notion of Masculine Gender Role Stress (MGRS) which assumes that rigid commitment to masculine schemata for appraisal and coping with life's problems may both produce stress and result in dysfunctional coping patterns in men. Previous findings obtained in a non-clinical sample pointed to the ability of the MGRS General scale to predict different forms of irrational fears. Using a predominantly psychologically distressed sample, the present study replicated this finding. In addition, different subordinate concepts of MGRS (Physical inadequacy, Emotional inexpressiveness, Subordination to women, Intellectua…
The processing of mispredicted and unpredicted sensory inputs interact differently with attention
2018
International audience; Prediction and attention are fundamental brain functions in the service of perception. Interestingly, previous investigations found prediction effects independent of attention in some cases but attention-dependent in other cases. The discrepancy might be related to whether the prediction effect was revealed by comparing mis-predicted event (where there is incorrect prediction) or unpredicted event (where there is no precise prediction) against predicted event, which are associated with different precision-weighted prediction error. Here we conducted a joint analysis on four published electroencephalography (EEG) datasets which allow for proper dissociation of mispred…
Age at surgery as a predictor of cognitive improvements in patients with drug-resistant temporal epilepsy
2017
Temporal lobe epilepsy (TLE) surgery is an effective procedure that can produce cognitive changes. However, the prognostic factors related with cognitive outcomes need to be better understood. The aim of the present study is to know if age at surgery is a reliable predictor of verbal memory competence and considering factors such as: hemisphere; type of surgery; pre-surgical seizure frequency; and epilepsy duration. Sixty-one typically dominant patients with drug-resistant TLE (34 with left TLE [L-TLE] and 27 with right TLE [R-TLE]) underwent a neuropsychological assessment before and a year after surgery. Results showed that R-TLE patients had better evolution in short- and long-term verba…
Endemic hepatitis C virus infection in a Sicilian town: Further evidence for iatrogenic transmission
2002
The prevalence of and risk factors for HCV and HBV infections in the general population and the predictive value of ALT screening in identifying anti-HCV positive subjects have been evaluated in a small Sicilian town. A random 1:4 sampling from the census of the general population was performed. Anti-HCV, HCV-RNA, HCV genotype, HBsAg, and anti-HBc were tested. The linkage between HCV infection and potential risk factors was evaluated by multiple logistic regression analysis. Among 721 subjects studied, 75 (10.4%) were anti-HCV positive. The HCV infection rate increased from 0.4% in subjects 10-29 years of age to 34% in those > 60 years of age. Among the 75 anti-HCV positive subjects, 66.7% …
Estimated radiation exposure of German commercial airline cabin crew in the years 1960-2003 modeled using dose registry data for 2004-2015.
2016
Exposure to ionizing radiation of cosmic origin is an occupational risk factor in commercial aircrew. In a historic cohort of 26,774 German aircrew, radiation exposure was previously estimated only for cockpit crew using a job-exposure matrix (JEM). Here, a new method for retrospectively estimating cabin crew dose is developed. The German Federal Radiation Registry (SSR) documents individual monthly effective doses for all aircrew. SSR-provided doses on 12,941 aircrew from 2004 to 2015 were used to model cabin crew dose as a function of age, sex, job category, solar activity, and male pilots' dose; the mean annual effective dose was 2.25 mSv (range 0.01–6.39 mSv). In addition to an inverse …
Neuropsychological, clinical and cognitive insight predictors of outcome in a first episode psychosis study.
2012
The outcome of first episode psychosis (FEP) is highly variable and difficult to predict. We studied prospectively the impact of poor insight and neuropsychological deficits on outcomes in a longitudinal cohort of 127 FEP patients. Participants were assessed on 5 domains of cognitive function and 2 domains of insight (clinical and cognitive). At 12. months, patients were assessed again for symptom severity and psychosocial function. Regression analyses revealed that cognitive insight (a measure of self-reflectiveness and self-certainty) was the best baseline predictor of overall psychopathology at 12. months whereas executive function performance at admission to the study indicated later se…
Automatic fuzzy classification of the washout curves from magnetic resonance first-pass perfusion imaging after myocardial infarction.
2005
International audience; Abstract: Objectives: We sought to investigate the diagnostic ability of cardiac magnetic resonance imaging (MRI) perfusion in acute reper-fused myocardial infarction. The study used fuzzy logic to automatically classify signal intensity-time curves from myocardial segments into 3 categories: normal, hypointense, and Hyperintense. Materials and Methods: Thirty-eight patients with myocardial infarction underwent short-axis cine-MRI and contrast-enhanced MRI to provide data on wall thickening and the transmural extent of infarction. Of these, 17 had a second cardiac MRI to ascertain the functional recovery in each segment. Results: The fuzzy logic based classification …
Chronic hepatitis C: the viral load per liver cell before treatment as a new marker to predict long-term response to IFN-α therapy
1998
Abstract Background/Aims: So far, there are no reliable parameters that can predict the long-term sustained response to treatment with interferon-α in patients with chronic hepatitis C. In this study, we have developed a semi-quantitative method to determine the viral load per liver cell and have correlated this factor with the outcome of hepatitis C patients treated with interferon-α. Methods: Hepatitis C virus RNA levels were measured in serum, peripheral blood mononuclear cells and liver cells of randomly chosen hepatitis C patients before treatment with interferon-α ( n =37). The number of cells present in the liver biopsies was determined by a polymerase chain reaction-based quantitati…
Long-Term Determinants of Muscle Strength Decline: Prospective Evidence from the 22-Year Mini-Finland Follow-Up Survey
2012
Objectives: To examine long-term changes in handgrip strength and the factors predicting handgrip strength decline. Design: Longitudinal cohort study with 22 years of follow-up. Setting: Population-based Mini-Finland Health Examination Survey in Finland. Participants: Nine hundred sixty-three men and women aged 30 to 73 at baseline. Measurements: Handgrip strength was measured using a handheld dynamometer at baseline and follow-up. Information on potential risk factors, namely lifestyle and chronic conditions, and their changes throughout the follow-up were based on health interviews. Results: Based on linear mixed-effect models, midlife physically strenuous work, excess body weight, smokin…
Physical inactivity and obesity: A vicious circle.
2008
OBJECTIVE: Physical activity (PA) begins to decline in adolescence with a concomitant increase in weight. We hypothesized that a vicious circle may arise between decreasing PA and weight gain from adolescence to early adulthood. METHODS AND PROCEDURES: PA and self-perceived physical fitness assessed in adolescents (16-18 years of age) were used to predict the development of obesity (BMI > or =30 kg/m(2)) and abdominal obesity (waist >/=88 cm in females and > or =102 cm in males) at age 25 in 4,240 twin individuals (90% of twins born in Finland, 1975-1979). Ten 25-year-old monozygotic (MZ) twin pairs who were discordant for obesity (with a 16 kg weight difference) were then carefull…
