Delayed Mid-Sleep Time Associated With Weight Gain While Controlling for Eating Behaviors and Attention Deficit Hyperactivity Disorder Symptoms During the COVID-19 Pandemic.

Objective: Society's sleep-wake cycle and eating behaviors have altered and are considered the psychological outcomes of the coronavirus disease-2019 (COVID-19) pandemic. Our aim was to examine the relationship between sleep-wake rhythms, eating behaviors (dieting, oral control, and bulimic behaviors), and attention deficit hyperactivity disorder (ADHD) symptoms with weight gain during the COVID-19 pandemic.

Methods: The participants were 578 female university students divided into three groups based on weight change during COVID-19 who lost weight, whose weight did not change (nWC), and who gained weight (WG).

Feeding and Eating Disorders in the Context of Circadian Rhythms.

A circadian rhythm is a 24-hour rhythm controlled by a master clock, the suprachiasmatic nucleus, and driven by synchronizing internal/external zeitgebers. Food intake is one of the most important external cues/zeitgebers. Studies in humans and animals have shown that misalignment of food intake leads to chronodisruption, which is associated with metabolic disruption, obesity, and disordered eating attitudes.

Heterogeneity of associations between dissociation and attention deficit symptoms.

Childhood trauma and dissociative experiences are suggested to be predisposing transdiagnostic factors for attention deficit /hyperactivity disorder (ADHD) as well as many psychiatric disorders. Trauma-related symptoms such as motor restlessness, emotional instability, and concentration problems can mimic, trigger, or exacerbate ADHD symptoms. Moreover, given the relationship between ADHD and trauma-induced distress, it has been suggested that dissociative experiences and attention problems may reveal overlapping characteristics.

Decreased miR-15b-5p/miR-155-5p levels and increased miR-134-5p/miR-652-3p levels among BD patients under lithium treatment.

Background: There is an increasing interest about the role of miRNAs in the pathogenesis of bipolar disorder (BD). In this study, we aimed to examine the role of miRNAs as potential diagnostic and clinical biomarkers in BD.

Methods: Fifteen miRNAs in plasmas obtained from BD patients (n = 66) and from the healthy control group (n = 66) were analyzed by a qPCR test.
