Smoking prevalence is higher amongst individuals with schizophrenia and depression compared with the general population. Mendelian randomisation (MR) can examine whether this association is causal using genetic variants identified in genome-wide association studies (GWAS). There was strong evidence to suggest smoking is a risk factor for both schizophrenia (odds ratio (OR) 2.27, 95% confidence interval… Continue reading Evidence for causal effects of lifetime #smoking on risk for #depression and #schizophrenia: a Mendelian randomisation study

Temperature and #mental health: Evidence from the spectrum of mental health outcomes
This paper characterizes the link between ambient temperatures and a broad set of mental health outcomes. We find that higher temperatures increase emergency department visits for mental illness, suicides, and self-reported days of poor mental health. Specifically, cold temperatures reduce negative mental health outcomes while hot temperatures increase them. Our estimates reveal no evidence of… Continue reading Temperature and #mental health: Evidence from the spectrum of mental health outcomes
A Randomized Controlled Trial of #Metacognitive Therapy for #Depression: Analysis of 1-Year Follow-Up
..low mood and depression is prolonged by perseverative thinking styles, such as depressive rumination, worry, and other unhelpful self-regulation strategies. This thinking style, called the cognitive attentional syndrome (CAS; Wells and Matthews, 1994) is influenced by positive and negative metacognitive beliefs about uncontrollability and danger of rumination and worry as well as maladaptive executive control… Continue reading A Randomized Controlled Trial of #Metacognitive Therapy for #Depression: Analysis of 1-Year Follow-Up
Effect of different #nap opportunity durations on short-term maximal performance, attention, feelings, muscle soreness, fatigue, #stress and sleep.
The aim of the present study was to determine the effect of different nap opportunity durations on short-term maximal performance, attention, feelings, muscle soreness, fatigue, stress and sleep. Twenty physically active men (age: 21.1 ± 3.6 years, height: 176.4 ± 5.7 cm, body-mass: 72 ± 10.8 kg) performed the 5-jump and the digit-cancellation (i.e., attention) tests after four randomized nap opportunity conditions: no-nap opportunity… Continue reading Effect of different #nap opportunity durations on short-term maximal performance, attention, feelings, muscle soreness, fatigue, #stress and sleep.
The bright side of dark: Exploring the positive effect of #narcissism on perceived stress through mental toughness
Previous research reported that Subclinical Narcissism (SN) may increase Mental #Toughness (MT) resulting in positive outcomes such as lower psychopathy, higher school grades and lower symptoms of depression. We conducted three studies (N = 364, 240 and 144 for studies 1, 2 and 3, respectively) to test a mediation model, which suggests that SN may increase MT… Continue reading The bright side of dark: Exploring the positive effect of #narcissism on perceived stress through mental toughness
Efficacy and safety of #anti-inflammatory agents for the treatment of major #depressive disorder: a systematic review and meta-analysis of randomised controlled trials
..Four studies explored the antidepressant effects of NSAIDs in addition to traditional antidepressants. In all four studies, celecoxib was added at the same dose (400 mg/day). Traditional antidepressants used were sertraline, fluoxetine and reboxetine. We combined these studies for a subgroup meta-analysis, finding that antidepressants combined with celecoxib were better than antidepressants alone, leading to a… Continue reading Efficacy and safety of #anti-inflammatory agents for the treatment of major #depressive disorder: a systematic review and meta-analysis of randomised controlled trials
Stress related disorders and subsequent risk of life threatening #infections: population based sibling controlled cohort study
..144 919 individuals with stress related disorders (post-traumatic stress disorder (PTSD), acute stress reaction, adjustment disorder, and other stress reactions) identified from 1987 to 2013 ..Stress related disorders were associated with all studied life threatening infections, with the highest relative risk observed for meningitis (sibling based analysis 1.63 (1.23 to 2.16)) and endocarditis (1.57 (1.08 to… Continue reading Stress related disorders and subsequent risk of life threatening #infections: population based sibling controlled cohort study
Association Between High School #Personality Phenotype and #Dementia 54 Years Later in Results From a National US Sample
To examine whether personality during adolescence—a time when preclinical dementia pathology is unlikely to be present—confers risk of dementia in later life and to test whether associations could be accounted for by health factors in adolescence or differed across socioeconomic status (SES). Lower risk of dementia was associated with higher levels of vigor (hazard ratio… Continue reading Association Between High School #Personality Phenotype and #Dementia 54 Years Later in Results From a National US Sample
Relationship Between Daily #Stress, #Depression Symptoms, and #Facebook Addiction Disorder in Germany and in the United States
This study investigated the link between experience of daily stress, depression symptoms, and the Facebook Addiction Disorder (FAD) in Germany and in the United States. In samples from both countries (German sample: N = 531; U.S. sample: N = 909), daily stress was positively associated with FAD. Depression symptoms significantly positively moderated this positive relationship. Thus, current findings demonstrate… Continue reading Relationship Between Daily #Stress, #Depression Symptoms, and #Facebook Addiction Disorder in Germany and in the United States
