First-generation antipsychotics and QTc: any role for mediating variables?

OBJECTIVE: Corrected QT (QTc) interval prolongation is often associated with use of first-generation antipsychotics (FGAs). However, other factors require appropriate consideration, including age and gender, the role of other known medications associated with QTc prolongation, and severe comorbid conditions, such as co-occurring alcohol abuse/dependence. We aimed to study potential mediating roles of different, related, candidate variables on QTc. METHODS: We capitalized on data from a large (N = 2366), cross-sectional, national survey, the STAR Network QTc study, using a representative sample of people taking FGAs, and recruited from mental health services across Italy. RESULTS: About one-third of the sample was treated with FGAs, and almost one-tenth of the subjects took a different, additional, drug known to cause QTc prolongation. Our findings confirmed that there is an impact from FGAs, age, gender, alcohol misuse, and concurrent risky drugs on QTc. However, comorbid alcohol abuse/dependence and concurrent risky drugs did not mediate the effect of FGAs on QTc. CONCLUSIONS: Our findings showed that FGAs, concurrent risky drugs, and alcohol use disorders prolonged QTc. FGAs had a direct effect on QTc, confirming the need for clinicians to monitor a risk that could lead to sudden unexplained death. Copyright © 2016 John Wiley & Sons, Ltd.

Stigmatizing Attitudes and Beliefs About Anorexia and Bulimia Nervosa Among Italian Undergraduates.

Stigmatizing attitudes toward eating disorders (EDs) may lead to reduced treatment seeking. We aimed to estimate the prevalence of stigmatizing trends and beliefs related to anorexia nervosa (AN) and bulimia nervosa (BN), and the associations with the experiential knowledge of the problem, in a large sample of Italian undergraduates. A total of 2109 participants completed an online survey including questionnaires related to stigmatizing beliefs toward AN and BN, and personal contacts with people with EDs. Undergraduates reported almost overlapping low levels of stigmatizing trends for AN and BN, apart from personal responsibility and social distance. Those aged 18 to 25 and living with family held higher stigmatizing attitudes. Stigma was lower in underweight participants and in those (12%) reporting a previous ED diagnosis. Although not improving stigmatizing attitudes, 83% of the sample was familiar with people with an ED. Antistigma actions to increase awareness on EDs and to improve treatment-seeking behaviors are needed.

Facial emotion recognition in alcohol and substance use disorders: A meta-analysis.

People with alcohol and substance use disorders (AUDs/SUDs) show worse facial emotion recognition (FER) than controls, though magnitude and potential moderators remain unknown. The aim of this meta-analysis was to estimate the association between AUDs, SUDs and FER impairment. Electronic databases were searched through April 2015. Pooled analyses were based on standardized mean differences between index and control groups with 95% confidence intervals, weighting each study with random effects inverse variance models. Risk of publication bias and role of potential moderators, including task type, were explored. Nineteen of 70 studies assessed for eligibility met the inclusion criteria, comprising 1352 individuals, of whom 714 (53%) had AUDs or SUDs. The association between substance related disorders and FER performance showed an effect size of -0.67 (-0.95, -0.39), and -0.65 (-0.93, -0.37) for AUDs and SUDs, respectively. There was no publication bias and subgroup and sensitivity analyses based on potential moderators confirmed core results. Future longitudinal research should confirm these findings, clarifying the role of specific clinical issues of AUDs and SUDs.
