Research has repeatedly verified high co-prevalence rates for bulimia and alcohol abuse. Two heuristics may help explain this co-occurrence. The self-inflation component of Steele and Josephs' myopia model has been evaluated and results have indicated that alcohol consumption results in decreased self-discrepancy. Research on Hull's self-awareness model also has largely found that alcohol decreases self-awareness among highly self-conscious individuals. Body size discrepancy and high self-awareness are believed to be core features of bulimia. Therefore, evidence that alcohol decreases body size discrepancy and self-awareness might clarify high rates of alcohol use in this population. A placebo-control design was used to examine the effect of alcohol on changes in body size discrepancy and self-awareness among female participants (N=57). However, results did not show a significant effect of alcohol on body size discrepancy or self-awareness, regardless of bulimic symptom severity.

Racial and Ethnic Disparities in Pediatric Counseling on Nutrition, Lifestyle, and Weight: A Secondary Analysis of the BP-CATCH Randomized Clinical Trial.
JAMA Netw Open
January 2025
Department of Pediatrics, The Children's Hospital at Montefiore, Albert Einstein College of Medicine, Bronx, New York.
Importance: Pediatric obesity and hypertension are highly correlated. To mitigate both conditions, provision of counseling on nutrition, lifestyle, and weight to children with high blood pressure (BP) measurements is recommended.
Objective: To examine racial and ethnic disparities in receipt of nutrition, lifestyle, and weight counseling among patients with high BP at pediatric primary care visits stratified by patients' weight status.
Use of Body Armor by EMS Clinicians, Workplace Violence, and Racial and Ethnic Disparities in Care.
JAMA Netw Open
January 2025
Department of Emergency Medicine, Mayo Clinic, Rochester, Minnesota.
Importance: There is a clear benefit to body armor against firearms; however, it remains unclear how these vests may influence day-to-day patient encounters when worn by emergency medical services (EMS).
Objective: To determine the association of ballistic vests worn by EMS clinicians with workplace violence (WPV) and disparities in care among racial and/or ethnic minority patients.
Design, Setting, And Participants: Prospective cohort study of a volunteer-based sample of EMS clinicians at a large, multistate EMS agency encompassing 15 ground sites across the Midwest from April 1, 2023, to March 31, 2024.
Baricitinib Provides Significant Improvements in Quality of Life and Functioning in Adults with Moderate-to-Severe Atopic Dermatitis with Baseline Body Surface Area ≤ 40% and Severe Itch.
Dermatol Ther (Heidelb)

Department of Dermatology, University of Tsukuba, Tsukuba, Japan.
Introduction: Patients with moderate-to-severe atopic dermatitis (AD), a body surface area (BSA) of ≤ 40%, and an itch numerical rating scale (NRS) score of ≥ 7 ("BARI itch dominant") have been characterized as an important group to consider for the oral janus kinase (JAK) 1/2 inhibitor baricitinib (BARI). Herein we aim to evaluate quality of life (QoL) and functioning outcomes in adult patients with BSA ≤ 40% and itch NRS ≥ 7 at baseline (BL) who received BARI 4 mg in the topical corticosteroid (TCS) combination trial BREEZE-AD7.
Materials: BREEZE-AD7 was a randomized, double-blind, placebo-controlled, parallel-group outpatient study involving adult patients with moderate-to-severe AD who received once-daily placebo or 2-mg or 4-mg BARI in combination with TCS for 16 weeks.
Is There a Need to Reassess Protein Intake Recommendations Following Metabolic Bariatric Surgery?
Curr Obes Rep
January 2025
Department of Nutrition Sciences, School of Health Sciences, Ariel University, Ariel, Israel.
Purpose Of Review: Protein intake is recognized as a key nutritional factor crucial for optimizing Metabolic Bariatric Surgery (MBS) outcomes by preventing protein malnutrition, preserving fat-free mass, and inducing satiety. This paper discusses the current evidence regarding protein intake and its impact on clinical outcomes following MBS.
Recent Findings: There are considerable gaps in the understanding of protein requirements following MBS, as existing guidelines are based on limited and inconsistent reports.
Family Size across the Life Course and Cognitive Decline in Older Mexican Adults.
J Gerontol B Psychol Sci Soc Sci
January 2025
College of Health Solutions, Arizona State University, Phoenix, AZ, USA.
Objectives: A growing body of research has identified associations between family size and cognition in older adults. These studies largely focus on older adults' own fertility history instead of sibship size, defined as one's number of siblings. Sibship size may impact cognitive development during early childhood, creating differences that may persist into late-life.
