Prehabilitation-Driven Changes in Frailty Metrics Predict Mortality in Patients With Advanced Liver Disease.

Introduction: Frailty is a predictor of morbidity and mortality in cirrhosis. Although evidence for prehabilitation is promising, the data for liver transplant (LT) candidates are limited. The primary aim of this study was to evaluate the effect of a novel prehabilitation strategy on changes in frailty metrics and survival in LT candidates.

Wearables, Physical Activity, and Exercise Testing in Liver Disease.

Physical inactivity is a major cause of deterioration in all forms of advanced liver disease. It is especially important as a driver of the components of the metabolic syndrome, with nonalcoholic fatty liver disease rapidly becoming the dominant cause of liver-related death worldwide. Growing realization of the health benefits of moderate-to-vigorous physical activity has captured the interest of persons who desire to improve their health, including those at risk for chronic liver injury.

Exercise in cirrhosis: Translating evidence and experience to practice.

Physical inactivity, sarcopenia, and frailty are highly prevalent, independent predictors of morbidity and mortality in patients with cirrhosis. Across a range of chronic diseases, exercise training is a key recommendation supported by guidelines and, for some conditions, even by governmental funding of exercise programmes. Consistent with the broader chronic disease literature, the evidence for a benefit of exercise in cirrhosis is promising.

Effect of High-Intensity Treadmill Exercise on Motor Symptoms in Patients With De Novo Parkinson Disease: A Phase 2 Randomized Clinical Trial.

Importance: Parkinson disease is a progressive neurologic disorder. Limited evidence suggests endurance exercise modifies disease severity, particularly high-intensity exercise.

Objectives: To examine the feasibility and safety of high-intensity treadmill exercise in patients with de novo Parkinson disease who are not taking medication and whether the effect on motor symptoms warrants a phase 3 trial.

Frailty as Tested by Gait Speed is an Independent Risk Factor for Cirrhosis Complications that Require Hospitalization.

Objectives: Frailty is a known risk factor for major life-threatening liver transplant complications, deaths, and waitlist attrition. Whether frailty indicates risk for adverse outcomes in cirrhosis short of lethality is not well defined. We hypothesized that clinical measurements of frailty using gait speed and grip strength would indicate the risk of subsequent hospitalization for the complications of cirrhosis.

The gap between clinically assessed physical performance and objective physical activity in liver transplant candidates.

Frailty with sarcopenia in cirrhosis causes liver transplant wait-list attrition and deaths. Regular physical activity is needed to protect patients with cirrhosis from frailty. We subjectively assess physical performance in selecting patients for transplant listing, but we do not know whether clinical assessments reflect the extent of activity patients actually perform.

Surgery versus nonsurgical treatment of lumbar spinal stenosis: a randomized trial.

Background: Primary care management decisions for patients with symptomatic lumbar spinal stenosis (LSS) are challenging, and nonsurgical guidance is limited by lack of evidence.

Objective: To compare surgical decompression with physical therapy (PT) for LSS and evaluate sex differences.

Design: Multisite randomized, controlled trial.

Links between osteoarthritis and diabetes: implications for management from a physical activity perspective.

Osteoarthritis (OA) and type 2 diabetes mellitus (T2DM) often coexist in older adults. Those with T2DM are more susceptible to developing arthritis, which has been traditionally attributed to common risk factors, namely, age and obesity. Alterations in lipid metabolism and hyperglycemia might directly impact cartilage health and subchondral bone, contributing to the development/progression of OA.

Comparing physical activity programs for managing osteoarthritis in overweight or obese patients.

Obesity is a well-known modifiable risk factor for osteoarthritis (OA) in weight-bearing joints, and is present in approximately 35% of individuals with OA. Obesity adds significant burden to individuals with OA and is associated with poorer functional status and greater disability. In addition to tackling OA-related impairments, such as pain and functional limitations, interventions in this population need to address bodyweight reduction, as well as promotion of active lifestyle behaviors.

Physical activity and physical function in individuals post-bariatric surgery.

Background: A better understanding of the physical activity behavior of individuals who undergo bariatric surgery will enable the development of effective post-surgical exercise guidelines and interventions to enhance weight loss outcomes. This study characterized the physical activity profile and physical function of 40 subjects 2-5 years post-bariatric surgery and examined the association between physical activity, physical function, and weight loss after surgery.

Methods: Moderate-to-vigorous intensity physical activity (MVPA) was assessed with the BodyMedia SenseWear® Pro (SWPro) armband, and physical function (PF) was measured using the physical function subscale of the 36-Item Short Form Health Survey instrument (SF-36(PF)).

Physical activity and physical function changes in obese individuals after gastric bypass surgery.

Background: Little is known about the effects of gastric bypass surgery (GBS) on physical activity and physical function. We examined the physical activity, physical function, psychosocial correlates to physical activity participation, and health-related quality of life of patients before and after GBS.

Methods: A total of 20 patients were assessed before and 3 months after GBS.
