Energy Drink (ED)-associated cardiovascular emergency visits have increased in recent years. Although a toxicity threshold has been established for caffeine, the safety profile of whole ED consumption has not yet been defined.

This systematic review was conducted following the PRISMA guidelines. Three reviewers conducted two separate systematic searches on PubMed on October 24 and December 3, 2019. Out of 250 potential records, 43 prospective clinical studies assessing the effects of ED on heart rate (HR) and/or any electrocardiographic (ECG) parameters were included. A meta-analysis was conducted to estimate pooled p-values using metap command for STATA 10.0.

After ED consumption, resting HR increased in 71.1% of studies (pooled p-value <0.001) but was only significant in 38%; HR during and after exercise increased in 55.5% (pooled p-value <0.001) and 71.4% of studies, respectively; QRS increased in all but two protocols; evidence on PR interval was contradictory, and corrected QT interval (QTc) increased compared to baseline in all but one study, exceeding the pathological limit value in two of them. T wave changes were seen in two studies, and one study reported a ratio of 5 to 1 in the number of ectopic beats.

Acute consumption of ED can alter the ECG in certain risk populations, posing a risk whose magnitude is yet to be determined. Caution should be exercised among at-risk and underage individuals but further research in these populations is warranted before restrictions are made.

Controlling for air-pollution, rainfall, temperature, demographic factors that measure population density, the proportion of the elderly, and health infrastructure including per capita health spending and the proportion of respiratory cases, does not diminish the predictive power of BMI in influencing the spatial incidence and spread of the virus. The association between adult BMI and measures of spatial outcomes is especially pronounced among educated populations in urban settings, and impervious to conditioning on differences in testing rates across states. We find that among women, BMI proxies for a range of comorbidities (hemoglobin, high blood pressure and high glucose levels) that affects the severity of the virus while among men, these health indicators are also important, as is exposure to risk of contracting the virus as measured by work propensities. We conduct sensitivity checks and control for differences that may arise due to variations in timing of onset. Our results provide a readily available health marker that may be used to identify and protect especially at-risk populations in developing countries like India.

Individuals with major depressive disorder often experience cognitive deficits. Cognitive remediation (CR) is an intervention aimed at improving cognition in psychiatric disorders. However, its efficacy on global and specific domains of cognition in adults with depression requires systematic investigation. Further, given individual differences in treatment outcome, moderators of CR effects in depression need to be identified.

We performed a systematic review and meta-analysis of published controlled trials of CR in adults with depression. We analyzed results from eight studies to estimate the efficacy of CR on global cognition and on six cognitive domains. We also examined three potential moderators, namely session format (individual vs. ML385 concentration group), treatment duration, and participants' age.

CR was found to improve global cognition (g=0.44), verbal memory (g=0.60), attention/processing speed (g=0.41), working memory (g=0.35), and executive functioning (g=0.30). No significant improvements emerged for visuospatial memory and verbal fluency. Furthermore, no significant moderating effect of participant's age, session duration or session format were observed.

Conclusions are limited by the small number of studies, the heterogeneity in cognitive measures, and the lack of indicators of everyday functioning.

Our meta-analysis supports the use of CR in improving global cognition in adults with major depressive disorder with a moderate effect size and this efficacy varies between cognitive domains.

To compare and characterize major depressive disorder (MDD) subtypes (i.e., pure atypical, pure melancholic and mixed atypical-melancholic) and depression symptoms in persons with multiple sclerosis (PwMS) with persons without MS (Pw/oMS) fulfilling the DSM-5 criteria for a past 12-month MDD.

MDD in PwMS (n=92) from the Swiss Multiple Sclerosis Registry was compared with Pw/oMS (n=277) from a Swiss community-based study. Epidemiological MDD diagnoses were based on the Mini-SPIKE (shortened form of the Structured Psychopathological Interview and Rating of the Social Consequences for Epidemiology). Logistic and multinomial regression analyses (adjusted for sex, age, civil status, depression and severity) were computed for comparisons and characterization. Latent class analysis (LCA) was conducted to empirically identify depression subtypes in PwMS.

PwMS had a higher risk for the mixed atypical-melancholic MDD subtype (OR=2.22, 95% CI=1.03-4.80) compared to Pw/oMS. MDD in PwMS was specifically characterized by a higher risk of the two somatic atypical depression symptoms 'weight gain' (OR=6.91, 95% CI=2.20-21.70) and 'leaden paralysis' (OR=3.03, 95% CI=1.35-6.82) and the symptom 'irritable/angry' (OR=3.18, 95% CI=1.08-9.39).

MDD in PwMS was characterized by a higher risk for specific somatic atypical depression symptoms and the mixed atypical-melancholic MDD subtype. The pure atypical MDD subtype, however, did not differentiate between PwMS and Pw/oMS. Given the high phenomenological overlap with MS symptoms, the mixed atypical-melancholic MDD subtype represents a particular diagnostic challenge.
