Assessing Adherence to Multi-Modal Oura Ring Wearables From COVID-19 Detection Among Healthcare Workers.

Background Identifying early signs of a SARS-CoV-2 infection in healthcare workers could be a critical tool in reducing disease transmission. To provide this information, both daily symptom surveys and wearable device monitoring could have utility, assuming there is a sufficiently high level of participant adherence. Purpose The aim of this study is to evaluate adherence to a daily symptom survey and a wearable device (Oura Ring) among healthcare professionals (attending physicians and other clinical staff) and trainees (residents and medical students) in a hospital setting during the early stages of the COVID-19 pandemic.

Different biases in meta-analyses of case-control and cohort studies: an example from genomics and precision medicine.

Purpose: Meta-analyses of observational studies reduce the role of chance but also introduce bias because the individual component studies are not randomized. Further, it is plausible that the bias may be different in case-control and cohort studies. We explored these issues in meta-analyses of observational studies of Opioid Use Disorder (OUD).

Upper extremity bioimpedance before and after treadmill testing in women post breast cancer treatment.

Research on the effect of cardiorespiratory (CR) exercise on upper extremity (UE) limb volume is limited in women with breast cancer-related lymphedema (BCRL). The aim of this study was to compare changes in UE volume immediately following a symptom-limited CR treadmill test in women with and without BCRL. As part of a cross-sectional study, 133 women post unilateral BC treatment completed symptom-limited treadmill testing.

Cardiorespiratory Fitness in Women with and without Lymphedema following Breast Cancer Treatment.

Following breast cancer (BC) treatment, many women develop impairments that may impact cardiorespiratory (CR) fitness. The aims of this study were to 1) evaluate CR fitness in women following BC treatment, 2) evaluate differences in CR fitness in those with and without breast cancer-related lymphedema (BCRL) and compare these to age-matched norms, and 3) evaluate the contribution of predictor variables to CR fitness. 136 women post-BC treatment completed testing: 67 with BCRL, and 69 without.

Effects of modality change on health-related quality of life.

Patients with end-stage renal disease (ESRD) requiring renal replacement have impaired health-related quality of life (HRQoL), and there is general consensus that HRQoL improves with successful transplant and evidence of improvement with frequent hemodialysis. This study reports changes in HRQoL associated with changes in treatment modality to daily hemodialysis (DHD) and transplant among patients requiring renal replacement. This cohort study had assessments at baseline and 6-month following modality change.

Effects of modality change and transplant on peak oxygen uptake in patients with kidney failure.

Background: Exercise capacity as measured by peak oxygen uptake (Vo₂(peak)) is low in hemodialysis patients. The present study assesses determinants of VO₂(peak) in patients with chronic kidney failure who either changed kidney replacement modality to frequent hemodialysis therapy or received a kidney transplant.

Study Design: Cohort study with assessment at baseline and 6 months after modality change.

Habitual physical activity levels are associated with performance in measures of physical function and mobility in older men.

Objectives: To determine whether objectively measured physical activity levels are associated with physical function and mobility in older men.

Design: Cross-sectional.

Setting: Academic research center.

Adverse events associated with testosterone administration.

Background: Testosterone supplementation has been shown to increase muscle mass and strength in healthy older men. The safety and efficacy of testosterone treatment in older men who have limitations in mobility have not been studied.

Methods: Community-dwelling men, 65 years of age or older, with limitations in mobility and a total serum testosterone level of 100 to 350 ng per deciliter (3.

A randomized controlled trial of home-based exercise for cancer-related fatigue in women during and after chemotherapy with or without radiation therapy.

Background: Few studies have evaluated an individualized home-based exercise prescription during and after cancer treatment.

Objective: The purpose of this study was to evaluate the effectiveness of a home-based exercise training intervention, the Pro-self Fatigue Control Program on the management of cancer-related fatigue.

Interventions/methods: Participants (N = 119) were randomized into 1 of 3 groups: group 1 received the exercise prescription throughout the study; group 2 received their exercise prescription after completing cancer treatment; and group 3 received usual care.

Free testosterone levels are associated with mobility limitation and physical performance in community-dwelling men: the Framingham Offspring Study.

Context: Mobility limitation is associated with increased morbidity and mortality. The relationship between circulating testosterone and mobility limitation and physical performance is incompletely understood.

Objective: Our objective was to examine cross-sectional and prospective relations between baseline sex hormones and mobility limitations and physical performance in community-dwelling older men.

Interunit and intraunit reliability of the RT3 triaxial accelerometer.

Background: Interest in the quantification of physical activity is on the rise. Triaxial accelerometry has frequently been used; however, research on the reliability of these devices is limited. We examine the interunit and intraunit reliability of 22 RT3 triaxial accelerometers using a performance-documented laboratory agitator.

Health-related fitness and physical activity in patients with nonalcoholic fatty liver disease.

Unlabelled: Nonalcoholic fatty liver disease (NAFLD) has been referred to as the hepatic manifestation of the metabolic syndrome. There is a lower prevalence of metabolic syndrome in individuals with higher health-related fitness (HRF) and physical activity (PA) participation. The relationship between NAFLD severity and HRF or PA is unknown.

Exercise capacity and physical fitness in pediatric dialysis and kidney transplant patients.

Studies of exercise capacity in children with chronic kidney disease (CKD) are limited. We tested 25 pediatric kidney transplant (TX) recipients and 15 pediatric dialysis (DX) patients. Nine children in the DX group received kidney transplants and were retested 3 months following surgery (pre/post).

The comprehensive assessment of physical fitness in children following kidney and liver transplantation.

Background: Pediatric organ transplant recipients may have elevated cardiovascular (CV) risk. Low cardiorespiratory fitness (CRF) may contribute to CV risk; however, studies of CRF in children following kidney transplantation (KTx) and liver transplantation (LTx) are limited.

Methods: Laboratory testing included assessment of CRF (VO2peak), muscle strength, and body composition (%fat).

Objective measures of health-related quality of life over 24 months post-liver transplantation.

Many studies have reported improved health-related quality of life (HRQoL) from pre- to immediate post-orthotopic liver transplantation (OLT). However, few studies have evaluated longitudinal changes over the first 2 yr post-OLT and none have simultaneously examined objective measures of health-related fitness. A total of 50 OLT recipients (32 males,18 females; 51.

Exercise capacity and muscle structure in kidney recipient and twin donor.

Exercise capacity and muscle function are known to be abnormal in patients with renal disease. We present a case study in which we studied a kidney transplant recipient who received a kidney from his identical twin. Testing included maximal exercise testing with measurement of oxygen uptake (VO2max), isokinetic muscle function testing, body composition analysis using dual energy X-ray absorptiometry (DEXA) imaging and quality of life using The Medical Outcomes Short Form (SF-36) questionnaire.

Roles of nutrition and physical activity in musculoskeletal complications before and after liver transplantation.

End-stage liver disease (ESLD) affects thousands of people in the United States annually. Improvements in survival after liver transplantation have broadened the indications for its use as a proven therapy for ESLD, rapidly increasing the number of transplant candidates. However, the number of patients awaiting transplantation far surpasses the donor supply, resulting in lengthy waiting times.
