The Role of Nutrition in Managing Muscle Disorders.

Many myopathies in horses can be managed by exercise regimes and dietary modifications. This includes modifying the amount of nonstructural carbohydrate, fat, amino acids, vitamin E, and selenium based on the horse's specific myopathy, metabolic status, exercise program, and optimal body weight. Because dietary recommendations differ substantially between myopathies, it is imperative to establish a specific diagnosis.

Need of the hour: A service failure recovery reorientation for U.S. hospitals.

Issue: Many hospitals in the United States are facing significant postpandemic operational challenges largely as a result of increasing demand for health care services. Operational issues increase the risk of service failures. Improving the patient experience after service failures may lead to better outcomes for both patients and hospitals.

Changes in Muscle Quality Following Short-Term Resistance Training in Older Adults: A Comparison of Echo Intensity and Texture Analysis.

Background: Skeletal muscle echo intensity (EI) is associated with functional outcomes in older adults, but resistance training interventions have shown mixed results. Texture analysis has been proposed as a novel approach for assessing muscle quality, as it captures spatial relationships between pixels. It is unclear whether texture analysis is able to track changes following resistance training.

Evaluating AI Methods for Pulse Oximetry: Performance, Clinical Accuracy, and Comprehensive Bias Analysis.

Blood oxygen saturation (SpO) is vital for patient monitoring, particularly in clinical settings. Traditional SpO estimation methods have limitations, which can be addressed by analyzing photoplethysmography (PPG) signals with artificial intelligence (AI) techniques. This systematic review, following PRISMA guidelines, analyzed 183 unique references from WOS, PubMed, and Scopus, with 26 studies meeting the inclusion criteria.

Classification of variants of reduced penetrance in high-penetrance cancer susceptibility genes: Framework for genetics clinicians and clinical scientists by CanVIG-UK (Cancer Variant Interpretation Group-UK).

Purpose: Current practice is to report and manage likely pathogenic/pathogenic variants in a given cancer susceptibility gene as though having equivalent penetrance, despite increasing evidence of intervariant variability in risk associations. Using existing variant interpretation approaches, largely based on full-penetrance models, variants in which reduced penetrance is suspected may be classified inconsistently and/or as variants of uncertain significance. We aimed to develop a national consensus approach for such variants within the Cancer Variant Interpretation Group UK (CanVIG-UK) multidisciplinary network.

Changes in hospital-supported substance use services across US nonprofit hospitals, 2015-2021.

Substance use remains a timely and important community need to understand and address. Nonprofit hospitals are in a unique position to identify needs and develop programs in response to substance use challenges in their communities. To better understand how nonprofit hospitals do this, we collected data from community health needs assessments and their corresponding implementation strategy (IS) to address these needs for a 20% random sample of hospitals in each state of the United States over 2 periods (2015-2018 and 2019-2021).

The effects of resistance training to near volitional failure on motor unit recruitment during neuromuscular fatigue.

Background: It is unclear whether chronically training close to volitional failure influences motor unit recruitment strategies during fatigue.

Purpose: We compared resistance training to near volitional failure . non-failure on individual motor unit action potential amplitude (MUAP) and surface electromyographic excitation (sEMG) during fatiguing contractions.

Enhancing CNS mitophagy: drug development and disease-relevant models.

Mitophagy, the selective degradation of mitochondria, is impaired in many neurodegenerative diseases (NDs), resulting in an accumulation of dysfunctional mitochondria and neuronal damage. Although enhancing mitophagy shows promise as a therapeutic strategy, the clinical significance of mitophagy activators remains uncertain due to limited understanding and poor representation of mitophagy in the central nervous system (CNS). This review explores recent insights into which mitophagy pathways to target and the extent of modulation necessary to be therapeutic towards NDs.

Cost-Associated Unmet Dental, Vision, And Hearing Needs Among Low-Income Medicare Advantage Beneficiaries.

Medicare Advantage (MA) supplemental benefits offered at no or low premiums are a key value proposition for low-income beneficiaries. Despite nearly $20 billion in rebate payments to MA plans for funding supplemental benefits, their quality or enrollee access is not monitored. Using 2018-19 Medicare Current Beneficiary Survey data linked to MA plan data, we found that regardless of plan benefit generosity, low-income beneficiaries were more likely to report dental, vision, and hearing unmet needs because of cost.

Racial and ethnic differences in the receipt of continuous positive airway pressure treatment for obstructive sleep apnea.

Objective: To examine the pattern of health services access and utilization that may contribute to racial/ethnic disparities in receiving continuous positive airway pressure (CPAP) treatment for obstructive sleep apnea (OSA).

Methods: This cross-sectional study used a national sample from the All of Us Research Program, which included over 80 % of participants from underrepresented populations in biomedical research. Study participants included adults aged 18 years and older diagnosed with OSA (N = 8518).

The PS4-likelihood ratio calculator: flexible allocation of evidence weighting for case-control data in variant classification.

Background: The 2015 American College of Medical Genetics/Association of Molecular Pathology (ACMG/AMP) variant classification framework specifies that case-control observations can be scored as 'strong' evidence (PS4) towards pathogenicity.

Methods: We developed the PS4-likelihood ratio calculator (PS4-LRCalc) for quantitative evidence assignment based on the observed variant frequencies in cases and controls. Binomial likelihoods are computed for two models, each defined by prespecified OR thresholds.

The Ecology of Economic Distress and Life Expectancy.

Objectives: To determine whether life expectancy (LE) changes between 2000 and 2019 were associated with race, rural status, local economic prosperity, and changes in local economic prosperity, at the county level.

Methods: Between 12/1/22 and 2/28/23, we conducted a retrospective analysis of 2000 and 2019 data from 3,123 United States counties. For Total, White, and Black populations, we compared LE changes for counties across the rural-urban continuum, the local economic prosperity continuum, and for counties in which local economic prosperity dramatically improved or declined.

United States Federal Policies Contributing to Health and Health Care Inequities in Puerto Rico.

Puerto Rico, a territory of the United States since 1898, has recently experienced an increasing frequency and intensity of natural disasters and public health emergencies. In 2022, Hurricane Fiona became the latest storm to attract media attention and cast a light on Puerto Rico's deteriorating conditions, including infrastructural failings, health care provider shortages, and high levels of chronic illness. Although recent events have been uniquely devastating, decades of inequitable US federal policy practices have fueled the persistence of health inequities in the territory.

Medicare Advantage Plan Star Ratings and County Social Vulnerability.

Importance: The star rating of a Medicare Advantage (MA) plan is meant to represent plan performance, and it determines the size of quality bonuses. Consumer access to MA plans with a high star rating may vary by the extent of social vulnerability in geographic regions.

Objective: To examine the association between a county's Social Vulnerability Index (SVI) and the star rating of a county's MA plans.

Weighting the United States Research Program data to known population estimates using raking.

Background: The Research Program aims to collect longitudinal health-related data from a million individuals in the United States. An inherent challenge of a non-probability sampling strategy through voluntary participation in is that findings may not be nationally representative for addressing health and health care at the population level. We generated survey weights for the data that can be used to address the challenge.

Use of calibration to improve the precision of estimates obtained from All of Us data.

Objectives: To highlight the use of calibration weighting to improve the precision of estimates obtained from All of Us data and increase the return of value to communities from the All of Us Research Program.

Materials And Methods: We used All of Us (2017-2022) data and raking to obtain prevalence estimates in two examples: discrimination in medical settings (N = 41 875) and food insecurity (N = 82 266). Weights were constructed using known population proportions (age, sex, race/ethnicity, region of residence, annual household income, and home ownership) from the 2020 National Health Interview Survey.

A comparison of techniques to determine active motor threshold for transcranial magnetic stimulation research.

The determination of active motor threshold (AMT) is a critical step in transcranial magnetic stimulation (TMS) research. As AMT is frequently determined using an absolute electromyographic (EMG) threshold (e.g.

Barriers and Facilitators to Establishing Partnerships for Substance Use Disorder Care Transitions Between Safety-Net Hospitals and Community-Based Organizations.

Background: The effectiveness of hospital-based transitional opioid programs (TOPs), which aim to connect patients with substance use disorders (SUD) to ongoing treatment in the community following initiation of medication for opioid use disorder (MOUD) treatment in the hospital, hinges on successful patient transitions. These transitions are enabled by strong partnerships between hospitals and community-based organizations (CBOs). However, no prior study has specifically examined barriers and facilitators to establishing SUD care transition partnerships between hospitals and CBOs.

Thrombotic risk and features of patients with inferior vena cava agenesis: a multicentre, retrospective, observational study.

Background: Inferior vena cava agenesis (IVCA) is a rare anomaly predisposing affected people to lower-limb venous thrombosis with low frequency of pulmonary embolism. Antenatal thrombosis and inherited thrombophilia have been suggested as causes of IVCA. However, there is little evidence on the clinical course and management of this condition.

Global prevalence of violence against children and adolescents during COVID-19: A meta-analysis.

Background: Recent studies suggest that children and adolescents are at an increased risk of experiencing violence during the COVID-19 pandemic. However, there is limited knowledge about the prevalence of violence against children and adolescents across different regions in the world.

Objective: To estimate the pooled prevalence of violence against children and adolescents during the COVID-19 pandemic and explore how geographical and methodological factors explain the variation across studies.

Examining the relationship between social determinants of health, measures of structural racism and county-level overdose deaths from 2017-2020.

Introduction: Despite being an important determinant of health outcomes, measures of structural racism are lacking in studies examining the relationship between the social determinants of health (SDOH) and overdose deaths. The aim of this study is to examine the association between per capita revenue generated from fines and forfeitures, a novel measure of structural racism, and other SDOH with county-level overdose deaths from 2017-2020.

Methods: This longitudinal analysis of 2,846 counties from 2017-2020 used bivariate and multivariate Generalized Estimating Equations models to estimate associations between county overdose mortality rates and SDOH characteristics, including the fines and forfeitures measure.

Task-specific resistance training adaptations in older adults: comparing traditional and functional exercise interventions.

Muscle strength declines ∼3% per year after the age of 70. Resistance training guidelines for older adults are often based on free-weight and machine exercises, which may be inaccessible and lack carryover to activities of daily living. We tested the hypothesis that resistance training adaptations in older adults are task-specific.

Combined action observation and mental imagery versus neuromuscular electrical stimulation as novel therapeutics during short-term knee immobilization.

Limb immobilization causes rapid declines in muscle strength and mass. Given the role of the nervous system in immobilization-induced weakness, targeted interventions may be able to preserve muscle strength, but not mass, and vice versa. The purpose of this study was to assess the effects of two distinct interventions during 1 week of knee joint immobilization on muscle strength (isometric and concentric isokinetic peak torque), mass (bioimpedance spectroscopy and ultrasonography), and neuromuscular function (transcranial magnetic stimulation and interpolated twitch technique).
