Depression, suicidality and alcohol abuse among medical and business students.We determined the prevalence and correlates of depression, alcohol abuse and suicidal ideation among medical and business students in Trinity College, Dublin and University College, Dublin. We rated depression and suicidal ideation in the past month with the Beck Depression Inventory (BDI) and alcohol abuse with the CAGE. Of 539 students registered, 338 (62.7%) responded. 47 (13.9%) students were depressed, scoring > or = 10 on the BDI. 83 (24.6%) students had an alcohol use disorder (CAGE > or = 2). Alcohol abuse was more common among business students than medical students (AOR = 2.9; 95% C.I. = 1.7-5.1); there were no other inter-faculty differences. 20 (5.9%) students reported suicidal ideation in the last month. Suicidal ideation correlated positively with stressful life events (AOR = 1.4; 95% C.I.= 1.1-1.7), and negatively with social support (AOR = 0.6; 95/ C.I. =0.5-0.7). These findings suggest that students are a vulnerable group, and underscore the need for mental health education and psychosocial support services in universities.
Fine mapping of ZNF804A and genome-wide significant evidence for its involvement in schizophrenia and bipolar disorder.A recent genome-wide association study (GWAS) reported evidence for association between rs1344706 within ZNF804A (encoding zinc-finger protein 804A) and schizophrenia (P=1.61 × 10(-7)), and stronger evidence when the phenotype was broadened to include bipolar disorder (P=9.96 × 10(-9)). In this study we provide additional evidence for association through meta-analysis of a larger data set (schizophrenia/schizoaffective disorder N=18 945, schizophrenia plus bipolar disorder N=21 274 and controls N=38 675). We also sought to better localize the association signal using a combination of de novo polymorphism discovery in exons, pooled de novo polymorphism discovery spanning the genomic sequence of the locus and high-density linkage disequilibrium (LD) mapping. The meta-analysis provided evidence for association between rs1344706 that surpasses widely accepted benchmarks of significance by several orders of magnitude for both schizophrenia (P=2.5 × 10(-11), odds ratio (OR) 1.10, 95% confidence interval 1.07-1.14) and schizophrenia and bipolar disorder combined (P=4.1 × 10(-13), OR 1.11, 95% confidence interval 1.07-1.14). After de novo polymorphism discovery and detailed association analysis, rs1344706 remained the most strongly associated marker in the gene. The allelic association at the ZNF804A locus is now one of the most compelling in schizophrenia to date, and supports the accumulating data suggesting overlapping genetic risk between schizophrenia and bipolar disorder.
Prediction of hospital mortality by changes in the estimated glomerular filtration rate (eGFR).Deterioration of physiological or laboratory variables may provide important prognostic information. We have studied whether a change in estimated glomerular filtration rate (eGFR) value calculated using the (Modification of Diet in Renal Disease (MDRD) formula) over the hospital admission, would have predictive value. An analysis was performed on all emergency medical hospital episodes (N = 61964) admitted between 1 January 2002 and 31 December 2011. A stepwise logistic regression model examined the relationship between mortality and change in renal function from admission to discharge. The fully adjusted Odds Ratios (OR) for 5 classes of GFR deterioration showed a stepwise increased risk of 30-day death with OR's of 1.42 (95% CI: 1.20, 1.68), 1.59 (1.27, 1.99), 2.71 (2.24, 3.27), 5.56 (4.54, 6.81) and 11.9 (9.0, 15.6) respectively. The change in eGFR during a clinical episode, following an emergency medical admission, powerfully predicts the outcome.
Seasonal variation of serum vitamin D and the effect of vitamin D supplementation in Irish community-dwelling older people.Ireland is at 53°N, and its population risk of vitamin D deficiency is high. Previous Irish studies suggested a significant seasonality of serum 25-hydroxyvitamin D [25(OH)D] and a beneficial effect of supplementation in raising 25(OH)D levels. However, in Irish older people, little is known about the magnitude of the supplementation effect and whether supplementation affects 25(OH)D seasonality.
