Body weight reduction in women treated with tirzepatide by reproductive stage: a post hoc analysis from the SURMOUNT program.

Objective: Increases in adiposity and adverse changes in adipose distribution commonly occur in women during midlife and with the onset of menopause. This post hoc analysis assessed body weight changes with tirzepatide by reproductive stage.

Methods: Women participants from SURMOUNT-1, -3, and -4 randomized to tirzepatide (15 mg or maximum tolerated dose) or placebo were retrospectively categorized as being in the pre-, peri-, or post-menopause stages.

Body composition changes during weight reduction with tirzepatide in the SURMOUNT-1 study of adults with obesity or overweight.

Aims: We assessed changes in body composition following tirzepatide treatment in a substudy of participants with obesity or overweight from the SURMOUNT-1 trial, overall and post hoc in clinically relevant subgroups.

Materials And Methods: Substudy participants (n = 160 of the 2539 in SURMOUNT-1) underwent dual-energy X-ray absorptiometry (DXA) at baseline and Week 72. Body composition parameters were evaluated by analysis of covariance, logistic regression or Fisher's exact test.

Prevalence of obesity-related multimorbidity and its health care costs among adults in the United States.

Background: Overweight and obesity are associated with many obesity-related complications (ORCs) and drive increased health care costs. However, data on the impact of obesity severity on multimorbidity and the effect of multimorbidity on cost and health care resource utilization (HCRU) in people with overweight or obesity are limited.

Objective: To determine in reference to obesity-related multimorbidity (1) if prevalence increases with higher levels of weight class, (2) if higher levels of weight class are associated with an increased risk of multimorbidity at an earlier age, and (3) how HCRU and health care costs are impacted, including if there is a beyond-additive effect on ORC-related costs.

Time to weight plateau with tirzepatide treatment in the SURMOUNT-1 and SURMOUNT-4 clinical trials.

The rate of weight reduction during obesity treatment declines over time and eventually reaches a weight plateau. We investigated factors associated with time to weight plateau (TTWP) in tirzepatide-treated participants with obesity or overweight in a post-hoc analysis of SURMOUNT-1 and SURMOUNT-4 trials. Participants adherent to tirzepatide treatment and achieving ≥5% weight loss by primary endpoint (week 72 SURMOUNT-1; week 88 SURMOUNT-4) were included.

Disruption of Opioid Treatment Program Services Due to an Extreme Weather Event: An Example of Climate Change Effects on the Health of Persons Who Use Drugs.

Climate change and the opioid epidemic in combination may pose significant challenges for individuals with opioid use disorder due to potential disruptions in access to essential addiction treatment services caused by extreme weather events. Despite concerns over the escalating health impacts of climate change, limited research has documented and explored the vulnerability of patients enrolled in opioid treatment programs to disruptions caused by climate change and particularly extreme cold events. In this commentary, we describe the impact of a catastrophic flooding event during record-setting cold temperatures at an opioid treatment program in Seattle, WA.

Transhumeral prosthesis use and disuse affects whole-body angular momentum.

Background: Individuals with transhumeral limb loss have an increased risk of falling, potentially resulting from altered upper-body kinematics during gait. The purpose of this study was to investigate whole-body angular momentum as a measure of movement control, to gain an understanding of how these upper-body kinematics contribute to dynamic balance.

Methods: Eight participants with transhumeral limb loss and eight able-bodied control participants completed three gait trials at self-selected speeds.

Insulin Sensitivity and Insulin Secretion in Adults With Friedreich's Ataxia: The Role of Skeletal Muscle.

Introduction: Friedreich's ataxia (FRDA) is a multisystem disorder caused by frataxin deficiency. FRDA-related diabetes mellitus (DM) is common. Frataxin supports skeletal muscle mitochondrial oxidative phosphorylation (OXPHOS) capacity, a mediator of insulin sensitivity.

Fine-scale maps of malaria incidence to inform risk stratification in Laos.

Background: Malaria risk maps are crucial for controlling and eliminating malaria by identifying areas of varying transmission risk. In the Greater Mekong Subregion, these maps guide interventions and resource allocation. This article focuses on analysing changes in malaria transmission and developing fine-scale risk maps using five years of routine surveillance data in Laos (2017-2021).

Tirzepatide for the Treatment of Obstructive Sleep Apnea and Obesity.

Background: Obstructive sleep apnea is characterized by disordered breathing during sleep and is associated with major cardiovascular complications; excess adiposity is an etiologic risk factor. Tirzepatide may be a potential treatment.

Methods: We conducted two phase 3, double-blind, randomized, controlled trials involving adults with moderate-to-severe obstructive sleep apnea and obesity.

Weight reduction and the impact on apnea-hypopnea index: A systematic meta-analysis.

Unlabelled: Obstructive sleep apnea (OSA) is strongly associated with obesity. While the relationship between weight reduction and apnea-hypopnea index improvement has been documented, to our knowledge, it has not been quantified adequately. Therefore, this study aimed to quantify the relationship between weight reduction and AHI change.

Weight-Reduction Preferences Among OBSERVE Study Participants With Obesity or Overweight: Opportunities for Shared Decision-Making.

Objective: Limited recent evidence exists regarding weight-reduction preferences among people with obesity in the United States (US). We assessed preferred magnitudes of weight reduction among adults with obesity and how these preferences differ by participant characteristics.

Methods: The Perceptions, Barriers, and Opportunities for Anti-obesity Medications in Obesity Care: A Survey of Patients, Providers and Employers was a cross-sectional study assessing perceptions of obesity and anti-obesity medications among people with obesity, healthcare providers, and employers in the US.

Single-cell RNA-sequencing of human eosinophils in allergic inflammation in the esophagus.

Background: Eosinophils are elusive cells involved in allergic inflammation. Single-cell RNA-sequencing (scRNA-seq) is an emerging approach to deeply characterize cellular properties, heterogeneity, and functionality.

Objectives: We sought to comprehensively characterize the transcriptome and biological functions of human eosinophils at a site of severe allergic inflammation in the esophagus (ie, eosinophilic esophagitis [EoE]).

Transhumeral prosthesis use affects upper body kinematics and kinetics.

Background: Transhumeral (TH) limb loss leads to loss of body mass and reduced shoulder range of motion. Despite most owning a prosthesis, prosthesis abandonment is common. The consequence of TH limb loss and prosthesis use and disuse during gait may be compensation in the upper body, contributing to back pain or injury.

Eosinophil specialization is regulated by exposure to the esophageal epithelial microenvironment.

Distinct subsets of eosinophils are reported in inflammatory and healthy tissues, yet the functions of uniquely specialized eosinophils and the signals that elicit them, particularly in eosinophilic esophagitis, are not well understood. Herein, we report an ex vivo system wherein freshly isolated human eosinophils were cocultured with esophageal epithelial cells and disease-relevant proinflammatory (IL-13) or profibrotic (TGF-β) cytokines. Compared with untreated cocultures, IL-13 increased expression of CD69 on eosinophils, whereas TGF-β increased expression of CD81, CD62L, and CD25.

The effect of amplitude normalization technique, walking speed, and reporting metric on whole-body angular momentum and its interpretation during normal gait.

Whole-body angular momentum (WBAM) represents the cancellations of angular momenta that are produced during a reciprocal gait pattern. WBAM is sensitive to small changes and is used to compare dynamic gait patterns under different walking conditions. Study designs and the normalization techniques used to define WBAM vary and make comparisons between studies difficult.

Pathophysiology of Non-Esophageal Eosinophilic Gastrointestinal Disorders.

Eosinophilic gastrointestinal disorder (EGID) is an umbrella term encompassing a group of chronic, immune-mediated disorders characterized by eosinophil-rich inflammation affecting one or more segments of the gastrointestinal tract. A recent consensus in nomenclature and emerging data made possible through multi-center consortia are beginning to unravel the molecular and cellular underpinnings of EGIDs below the esophagus. These emerging findings are revealing both overarching commonalities related to a food allergen-driven, chronic, Th2-mediated immune response as well as location-specific nuances in the pathophysiology of the collective EGIDs.

Tirzepatide for the treatment of obstructive sleep apnea: Rationale, design, and sample baseline characteristics of the SURMOUNT -OSA phase 3 trial.

Background: Weight reduction is a standard recommendation for obstructive sleep apnea (OSA) treatment in people with obesity or overweight; however, weight loss can be challenging to achieve and maintain without bariatric surgery. Currently, no approved anti-obesity medication has demonstrated effectiveness in OSA management. This study is evaluating the efficacy and safety of tirzepatide for treatment of moderate to severe OSA in people with obesity.

Extended physiological proprioception is affected by transhumeral Socket-Suspended prosthesis use.

The objective of this study was to define targeted reaching performance without visual information for transhumeral (TH) prosthesis users, establishing baseline information about extended physiological proprioception (EPP) in this population. Subjects completed a seated proprioceptive targeting task under simultaneous motion capture, using their prosthesis and intact limb. Eight male subjects, median age of 58 years (range 29-77 years), were selected from an ongoing screening study to participate.

Malaria risk stratification in Lao PDR guides program planning in an elimination setting.

Malaria in Lao People's Democratic Republic (Lao PDR) has declined rapidly over the last two decades, from 279,903 to 3926 (99%) cases between 2001 and 2021. Elimination of human malaria is an achievable goal and limited resources need to be targeted at remaining hotspots of transmission. In 2022, the Center of Malariology, Parasitology and Entomology (CMPE) conducted an epidemiological stratification exercise to assign districts and health facility catchment areas (HFCAs) in Lao PDR based on malaria risk.

Adult patients with a claim for a weight management treatment from 01/01/2012-2/28/2019 were categorized into cohorts according to the highest intensity intervention received.

Baseline soil-transmitted helminth and schistosome infection in the Geshiyaro project, Ethiopia: A unique transmission interruption project using biometric fingerprinting for longitudinal individual analysis.

Background: The Geshiyaro project aims to assess the feasibility of interrupting transmission of soil-transmitted helminths (STH) and schistosome (SCH) infection in the Wolaita zone of southern Ethiopia through high coverage community-wide mass drug administration (MDA), in combination with improved water, sanitation, and hygiene services and behaviour change communication delivered through the existing health care infrastructure. To accurately measure treatment coverage a population census was conducted enrolling individuals with biometric fingerprinting and barcoded ID cards. This paper details the baseline census and parasitology surveys conducted before the start of any interventions.

The Association Between Depression and Substance Use Among Primary Care Patients With Comorbid Medical and Behavioral Health Conditions.

Introduction: The scope of primary care increasingly encompasses patient behavioral health problems, manifest typically through depression screening and treatment. Although substance use is highly comorbid with depression, it is not commonly identified and addressed in the primary care context. This study aimed to examine the association between the likelihood of substance use disorder and increased depression severity, both cross-sectionally and longitudinally, among a sample of 2409 patients from 41 geographically dispersed and diverse primary care clinics across the US.
