Impact of Changes in Rectus Femoris Cross-Sectional Area Measured by Ultrasound on the Prognosis of Patients With Acute Heart Failure.

Background: Low muscle mass in patients with acute heart failure (AHF) is associated with poor prognosis; however, this is based on a single baseline measurement, with little information on changes in muscle mass during hospitalization and their clinical implications. This study investigated the relationship between changes in rectus femoris cross-sectional area (RFCSA) on ultrasound and the prognosis of patients with AHF.

Methods and results: This is a retrospective evaluation of 284 AHF patients (mean [±SD] age 79.

Impact of sarcopenia and malnutrition on swallowing function utilizing ultrasonography in patients with acute heart failure: A retrospective cohort study.

Background & Aims: This study aimed to determine the impact of sarcopenia and nutritional risk on swallowing-related muscles by ultrasonography and dysphagia occurrence in older patients with acute heart failure (AHF) during hospitalization.

Methods: Patients with AHF aged ≥65 years without dysphagia (Food Intake LEVEL Scale [FILS] score ≥9) before admission were classified into four groups at admission: robust group, sarcopenia group (Asian Working Group for Sarcopenia 2019), nutritional risk group (geriatric nutritional risk index <92), and complicated group (with both sarcopenia and nutritional risk). Swallowing function (maximal hyoid displacement, geniohyoid muscle area and brightness, and maximal tongue pressure) and FILS were investigated from the medical records.

Effect of Electrical Muscle Stimulation on the Reduction of Muscle Volume Loss in Acute Heart Failure Patients.

Electrical muscle stimulation (EMS) is expected to be considered as an add-on therapy for the usual rehabilitation of patients with chronic heart failure (HF). However, it remains unclear whether EMS can reduce muscle volume loss in patients with acute HF (AHF) immediately after hospitalization. Therefore, the aim of this study was to investigate if EMS could reduce the lower-limb muscle volume loss in patients with AHF.

Effects of electrical muscle stimulation in frail elderly patients during haemodialysis (DIAL): rationale and protocol for a crossover randomised controlled trial.

Introduction: The phenomenon of population ageing is accompanied by increases in the number of elderly haemodialysis patients worldwide. The incidence of frailty is high in the haemodialysis population and is associated with poor clinical outcome. Although several interventions have been developed for use in general haemodialysis patients, the efficacy of such rehabilitation programmes in frail elderly patients on haemodialysis has not been elucidated.

Utility of Regular Management of Physical Activity and Physical Function in Hemodialysis Patients.

Background/aims: Several clinical practice guidelines recommend regular assessment of physical activity and physical function as part of routine care in hemodialysis patients. However, there is no clear evidence to support these recommendations. We investigated whether the proportion of attendance at a regular program for management of physical activity and physical function can predict all-cause mortality and cardiovascular events in hemodialysis patients.

Combined Contribution of Reduced Functional Mobility, Muscle Weakness, and Low Serum Albumin in Prediction of All-Cause Mortality in Hemodialysis Patients: A Retrospective Cohort Study.

Objectives: The combined effects of reduced functional mobility, muscle weakness, and low serum albumin on mortality in hemodialysis patients have not been clarified. Here, we examined the associations of reduced functional mobility, muscle weakness, and low serum albumin-both alone and in combination-with all-cause mortality in hemodialysis patients.

Methods: A total of 490 patients treated between July 2010 and October 2016 were enrolled retrospectively in this study.

Association between frailty and bone loss in patients undergoing maintenance hemodialysis.

Frailty is significantly associated with bone loss in the general population. However, it is unclear whether this association also exists in patients undergoing hemodialysis who have chronic kidney disease-mineral and bone disorder (CKD-MBD). This study aimed to assess the association between frailty and bone loss in patients undergoing hemodialysis.

Exercise Training in Elderly People Undergoing Hemodialysis: A Systematic Review and Meta-analysis.

Introduction: Previous reviews have indicated the effectiveness of exercise in people undergoing hemodialysis. However, these analyses did not take into account whether the subjects were elderly. We performed a systematic review of the effects of exercise training in elderly people undergoing hemodialysis and updated the evidence of exercise for people undergoing hemodialysis by adding recent research data.

Physical Activity Dose for Hemodialysis Patients: Where to Begin? Results from a Prospective Cohort Study.

Objective: Greater physical activity is associated with lower risk of mortality in persons with kidney disease; however, little is known about the appropriate dose of physical activity among hemodialysis patients. Here detected the minimum level of habitual physical activity to help inform interventions aimed at improving outcomes in the dialysis population.

Design: The design was prospective cohort study.

Changes in physical activity and risk of all-cause mortality in patients on maintence hemodialysis: a retrospective cohort study.

Background: A previous cohort study indicated a significant association of lower baseline level of physical activity in hemodialysis patients with elevated risks of mortality. However, there have been no reports regarding the association between changes in physical activity over time and mortality in hemodialysis patients. This study was performed to examine the prognostic significance of physical activity changes in hemodialysis patients.

Evaluating the effectiveness of exercise training on elderly patients who require haemodialysis: study protocol for a systematic review and meta-analysis.

Introduction: As the average age of haemodialysis patients rapidly increases around the world, the number of frail, elderly patients has increased. Frailty is well known to be an indicator of disability and a poor prognosis for haemodialysis patients. Exercise interventions have been safely and successfully implemented for middle-aged or younger patients undergoing haemodialysis.

Determinants of Slow Walking Speed in Ambulatory Patients Undergoing Maintenance Hemodialysis.

Walking ability is significantly lower in hemodialysis patients compared to healthy people. Decreased walking ability characterized by slow walking speed is associated with adverse clinical events, but determinants of decreased walking speed in hemodialysis patients are unknown. The purpose of this study was to identify factors associated with slow walking speed in ambulatory hemodialysis patients.

Relationship between lower extremity muscle strength and all-cause mortality in Japanese patients undergoing dialysis.

Background: Skeletal muscle wasting is common and insidious in patients who are undergoing hemodialysis. However, the association between lower extremity muscle strength and all-cause mortality remains unclear in this population.

Objective: The purpose of this study was to investigate the prognostic significance of lower extremity muscle strength on 7-year survival in a cohort of patients who were clinically stable and undergoing hemodialysis.

Association of habitual physical activity measured by an accelerometer with high-density lipoprotein cholesterol levels in maintenance hemodialysis patients.

After confirming the relationship between high-density lipoprotein cholesterol (HDL-C) levels and mortality in hemodialysis patients for study 1, we investigated the effect of physical activity on their HDL-C levels for study 2. In study 1, 266 hemodialysis patients were monitored prospectively for five years, and Cox proportional hazard regression confirmed the contribution of HDL-C to mortality. In study 2, 116 patients were recruited after excluding those with severe comorbidities or requiring assistance from another person to walk.
