Objective: Metabolic and bariatric surgery (MBS) is associated with substantial, but variable, weight outcomes. The gut microbiome may be a factor in determining weight trajectory, but examination has been limited by a lack of longitudinal studies with robust microbiome sequencing. This study aimed to describe changes in the microbiome and associations with weight outcomes more than 2 years post surgery.

Affect regulation models posit that aversive affective states drive binge-eating behavior, which then regulates negative emotions. However, recent findings among individuals with binge-eating disorder (BED) suggest that food-related anticipatory processes may precede and potentially explain the negative affect thought to drive binge eating. Specifically, studies using ecological momentary assessment (EMA) demonstrate that the negative affective state of "Guilt" (from the Positive and Negative Affect Schedule) most strongly predicts later binge eating in the natural environment, and it has been hypothesized that planning a binge or feeling that a binge-eating episode is inventible may account for the increases in Guilt observed prior to binge episodes.

Background: Among men who have sex with men (MSM) and transgender women (TGW), the dynamics of human papillomavirus (HPV) infections at different anatomical sites are not well understood. Information on HPV concordance between anatomic sites can inform the extent of autoinoculation, and susceptibility of different anatomic areas to HPV infection. We described and assessed correlates of HPV concordance across anal, oral, and genital samples.

Article Synopsis
  • * It compares outcomes of a group receiving IPT to those in a health education program, analyzing data from 113 girls aged 12-17 over a year.
  • * Results show that stronger emotional bonds in IPT led to less weight gain and fewer LOC eating episodes, while task collaboration was associated with weight gain in both groups, suggesting the need for more research on these relationships.

Objective: Emerging research indicates that skills acquisition may be important to behavior change in cognitive behavior therapy (CBT) for eating disorders. This study investigated whether skills use assessed in real time during the initial 4 weeks of CBT-based day treatment was associated with momentary eating disorder behavior change and rapid response to treatment.

Methods: Participants with DSM-5 bulimia nervosa or purging disorder (N = 58) completed ecological momentary assessments (EMA) several times daily for the first 28 days of treatment.

Introduction: Compulsive exercise is a transdiagnostic feature of eating disorders which adversely affects aspects of recovery, such as length of hospitalisation, risk of a chronic outcome, and risk of relapse. CompuLsive Exercise Activity TheraPy (LEAP) aims to reduce compulsive exercise through a cognitive behavioural approach. This study aims to investigate the effect of LEAP on compulsive exercise behaviour using subscales of the Compulsive Exercise Test (CET), a measure of exercise in individuals with eating disorders.

Objective: Prominent theories of binge-eating (BE) maintenance highlight dietary restriction as a key precipitant of BE episodes. Consequently, treatment approaches for eating disorders (including binge-eating disorder; BED) seek to reduce dietary restriction in order to improve BE symptoms. The present study tested the hypothesis that dietary restriction promotes BE among 112 individuals with BED.

It is well known that individuals with an eating disorder frequently experience a wide range of co-occurring mental health conditions which significantly impact eating disorders and quality of life. Clinicians attempt a variety of strategies to deal with the behavioral complexity of such co-occurrence, but little is known about empirically based interventions to treat this common comorbidity. The approach articulated by Wade and Colleagues highlights a potentially valuable strategy for empirically examining a range of treatment strategies to target the full spectrum of eating disorder psychopathology experienced by most patients with eating disorders.

Metabolic and bariatric surgery (MBS) is the most effective long-term treatment for Class III obesity. Reduced dietary intake is considered a behavioral driver of post-surgical weight loss, but limited data have examined this association. Therefore, this study examined prospective, longitudinal relationships between dietary intake and weight loss over 24 months following Roux-en-Y Gastric Bypass and Sleeve Gastrectomy.

Article Synopsis
  • - The study explores how various stressors affect tobacco use among trans women, focusing on both immediate (proximal) and larger societal (distal) factors like discrimination and violence.
  • - Out of 162 trans women in Chicago and Atlanta, 42.9% were found to smoke, with significant associations identified between tobacco use and issues such as homelessness, intimate partner violence, and involvement in commercial sex work.
  • - The findings suggest that tobacco cessation programs for trans women need to consider the complex stressors they encounter to be more effective.

Age-related weight gain prevention may reduce population overweight/obesity. Emerging adulthood is a crucial time to act, as rate of gain accelerates and health habits develop. Evidence supports self-weighing (SW) for preventing weight gain; however, how SW impacts psychological states and behaviors in vulnerable groups is unclear.
