Study Objectives: Disparities in access to care and healthcare system inequities result in race-based health care outcome differences. Excessive daytime sleepiness (EDS), as a general marker of health, is associated with all-cause mortality. We aimed to determine if the association and its effect size differ among various race and ethnic groups in a health care system with no or minimal race-based access limitation.

Unlabelled: Generative artificial intelligence utilizing transformer technology is widely seen as a groundbreaking advancement in applied artificial intelligence. The technology creates a unique opportunity to extract unstructured data from medical notes. In the current experiments, we extracted fundamental sleep parameters from polysomnography notes of veterans in the Corporate Data Warehouse national database using large language models.

Background: Approximately third of older adults report foot pain that can lead to reduced physical activity. In this study, we examined whether a novel therapeutic shoe that addresses both aesthetics to enhance acceptability and biomechanical features to reduce foot pain, might improve daily physical activity in older adults with mild to moderate foot pain.

Methods: In a 12-week crossover randomized controlled trial, older adults with chronic foot pain were randomly assigned to either group AB or BA.

The relationship between sleep apnea (SA) and mortality remains a topic of debate. We explored the relationship between the severity of SA and mortality and the effect of age on this association. Using a veterans' database, we extracted an apnea-hypopnea index (AHI) from physician interpretations of sleep studies by developing a natural language processing pipeline (with 944 manually annotated notes), which achieved more than 85% accuracy.

Objective: This study investigates the efficacy and feasibility of electrical stimulation (E-Stim) on sensory fibers of the plantar region during hemodialysis sessions, aiming to improve mobility in patients with diabetes by providing a connection between E-Stim and enhanced mobility with minimal patient effort required.

Research Design And Methods: Participants aged ≥18 years with diabetes undergoing hemodialysis and able to walk at least 10 m with or without aid were recruited and divided into an intervention group receiving 1-h intradialytic E-Stim three times a week and a control group using an identical nonfunctional device for 12 weeks. Gait, physical activity, patient-reported outcomes, and the technology acceptance model were assessed to evaluate the intervention's effectiveness and acceptance.

Background: Sleep apnea (SA) and insomnia (INS) are prevalent sleep disorders among referrals to sleep clinics. People with comorbid insomnia and sleep apnea (COMISA) suffer both disorders simultaneously. The epidemiology of COMISA is not well known in the Middle East including Iran.

Study Objectives: Excessive daytime sleepiness is prevalent and overwhelmingly stems from disturbed sleep. We hypothesized that age modulates the association between excessive daytime sleepiness and increased all-cause mortality.

Methods: We utilized the Veterans' Health Administration data from 1999-2022.

Purpose: While sleep apnea (SA) gets more prevalent with advancing age, the impact of age on the association between SA and health outcomes is not well known. We assessed the association between the severity of SA and all-cause mortality in different age groups using large longitudinal data.

Method: We applied a Natural Language Processing pipeline to extract the apnea-hypopnea index (AHI) from the physicians' interpretation of sleep studies performed at the Veteran Health Administration (FY 1999-2022).

Introduction: Nearly, a quarter of older adults suffer from frequent foot pain, impacting their quality of life. While proper footwear can alleviate this, design issues often hinder regular use. This study evaluated novel therapeutic footwear, designed for aesthetics and custom fit, to reduce foot pain.

Article Synopsis
  • - The study aimed to evaluate how incorporating the Prognostic Nutritional Index (PNI) into the existing U.S. Veterans Health Administration frailty index (VA-FI) impacts predictions of mortality and other health outcomes in Veterans with heart failure.
  • - Conducting a retrospective analysis on hospitalized Veterans with heart failure, the researchers defined malnutrition based on PNI scores and categorized Veterans into frailty groups using both VA-FI and the enhanced VA-FI-Nutrition.
  • - Results showed that 18.6% of Veterans were reclassified to a higher frailty status with VA-FI-Nutrition, which was linked to a shorter median time-to-death, indicating that nutrition plays a significant role in assessing fra

Unlabelled: We investigated the accuracy of (ICD) codes for the identification of veterans with rapid eye movement sleep behavior disorder. The charts of 139 randomly sampled veterans with ≥ 1 ICD-9 and ICD-10 code(s) for rapid eye movement sleep behavior disorder were reviewed for documentation of a suspected, previous, or current diagnosis; clinical symptoms; and/or empiric treatments for this disorder. Notably, 71 (51.

Background: Obstructive sleep apnea (OSA) is the most common sleep-realted respiratory disorder. It is frequently comorbid with cardiovascular, cerebrovascular, and metabolic diseases and is commonly observed in populations with these comorbidities. Investigators aimed to assess the effect of OSA on glycemic control in patients with diabetes.

Background: Diabetes is a prevalent chronic medical comorbid condition worldwide. Diabetes mellitus is associated with various sleep disorders.

Objectives: We aimed to determine the prevalence of poor sleep and the main factors of sleep interruptions in patients with diabetes mellitus.
