Purpose: This guideline provides evidence-based recommendations for adults with isocitrate dehydrogenase (IDH)-mutant grade 2 and grade 3 diffuse glioma, as classified in the 2021 World Health Organization (WHO) Classification of Tumours. It includes indications for radiation therapy (RT), advanced RT techniques, and clinical management of adverse effects.

Methods: The American Society for Radiation Oncology convened a multidisciplinary task force to address 4 key questions focused on the RT management of patients with IDH-mutant grade 2 and grade 3 diffuse glioma.

Objective: To determine whether an acceptance-based behavioral intervention (ABBI) produces better weight losses than standard behavioral treatment (SBT) among individuals reporting high internal disinhibition.

Methods: Participants were 162 adults with overweight or obesity (mean BMI 37.6 kg/m ) randomly assigned to ABBI or SBT.

Background: Obesity is public health problem associated with significant health risks and healthcare costs. Behavioral weight control programs produce clinically meaningful weight losses, however outcomes have high variability and maintenance continues to be a problem. The current study is an NIH-funded randomized clinical trial testing a novel approach, Acceptance-Based Behavioral Intervention (ABBI), that combines techniques from standard behavioral treatment (SBT) and Acceptance and Commitment Therapy (ACT).

Sociotropic cognition is a mindset characterized by a strong need for social approval and fear of interpersonal rejection. Sociotropic cognition has been associated with depression and health risk behavior in women, but few studies have specifically addressed eating disordered attitudes and behaviors, and studies including men are lacking. The purpose of the present study was to assess the influence of sociotropic cognition on eating-related attitudes and behaviors in men and women.

On average, participants in behavioral weight-loss interventions lose 8 kilograms (kg) at 6 months, but there is marked variability in outcomes with some participants losing little or no weight. Individuals with difficulties with internal disinhibition (i.e.

Larger portion sizes increase energy intake, yet it is unclear whether single-serving packages can reduce intake. This study examined the effects of providing breakfast foods in single-serving packages and nonportioned packages on energy intake of these foods during an 8-week behavioral weight-loss program. In fall 2005, 19 adults (mean body mass index [calculated as kg/m(2)]=31.

Context: Binge eating (BE) is common in overweight and obese individuals with type 2 diabetes mellitus, but little is known about how BE affects weight loss in this population.

Objective: To determine whether BE was related to 1-year weight losses in overweight and obese individuals with type 2 diabetes participating in an ongoing clinical trial.

Design, Setting, And Participants: The Look AHEAD (Action for Health in Diabetes) trial is a randomized controlled trial examining the long-term effect of intentional weight loss on cardiovascular disease in overweight and obese adults with type 2 diabetes.

Background: Household food availability is consistently linked to dietary intake; yet behavioral weight control treatment includes only minimal instruction on how to change the home environment to support dietary goals. This pilot study examined whether it is feasible to change the household food environments of behavioral weight loss participants through the use of a commercially available grocery home delivery service.

Methods: Overweight participants (N = 28; BMI = 31.

Objective: The disinhibition scale of the Eating Inventory predicts weight loss outcome; however, it may include multiple factors. The purpose of this study was to examine the factor structure of the disinhibition scale and determine how its factors independently relate to long-term weight loss outcomes.

Research Methods And Procedures: Exploratory factor analysis of the disinhibition scale was conducted on 286 participants in a behavioral weight loss trial (TRIM), and confirmatory factor analysis was conducted on 3,345 members of the National Weight Control Registry (NWCR), a registry of successful weight loss maintainers.

Purpose: To investigate whether fast food consumption and breakfast skipping are associated with weight gain during the transition from adolescence to adulthood.

Methods: A prospective study of 9919 adolescents participating in Waves II (age range 11-21 years) and III (age range 18-27 years) of the National Longitudinal Study of Adolescent Health. BMI z scores (zBMI) were computed using the 2000 Centers for Disease Control and Prevention growth charts.

Limiting meal variety decreases hedonic ratings of eaten foods more so than non-eaten foods, demonstrating sensory-specific satiety. Exposure to a food over time decreases the food's hedonic ratings, indicating monotony. The effect of limiting food group variety over time on long-term sensory-specific satiety and monotony is unknown.
