Acute effects of belt electrode-skeletal muscle electrical stimulation on microvascular responsiveness of the gastrocnemius muscle in healthy young men.

Purpose: Belt electrode-skeletal muscle electrical stimulation (B-SES) improves muscle strength, mass, and exercise tolerance. However, its effects on skeletal muscle microvascular responsiveness remain unclear. In this study, we investigated the acute effects of a single B-SES session on gastrocnemius microvascular responsiveness in healthy young men.

Occupational Therapy for Patients With Cardiovascular Disease - A Systematic Review.

Background: The prevalence of cardiovascular diseases (CVD) is high worldwide. Occupational therapy (OT) allows individuals to participate in activities of daily living (ADLs) and improves their quality of life. However, whether OT improves health-related quality of life (HRQOL), ADLs, fatigue, occupational performance, rehospitalization, and mortality in patients with CVD remains unclear.

Effects of veno-arterial extracorporeal membrane oxygenation on skeletal muscle function and interstitial PO in contracting muscle of normal rats.

Background: This study aimed to clarify the effects of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) on skeletal muscle oxygen pressure and function in rats.

Methods: Male Sprague-Dawley rats (2-3 months old, n = 17) were randomized into control and VA-ECMO groups. All animals were anesthetized and mechanically ventilated.

Cerebral Hemodynamics Measured by Wearable Near-Infrared Spectroscopy During Bedside Mobilization in a Patient With Chronic Heart Failure Hospitalized for Acute Exacerbation.

This report aimed to investigate the relationship between cerebral hemodynamics and orthostatic hypotension (OH) in a patient with acute exacerbation of chronic heart failure (HF) by measuring oxyhemoglobin (OHb) and regional cerebral oxygen saturation (rSO) using the wearable near-infrared spectroscopy (NIRS) device for risk management. A 61-year-old man was diagnosed with acute exacerbation of chronic HF. The patient was admitted to the hospital for the first time on day 0, and the first NIRS was performed on day 9.

Preoperative Posterior Pelvic Tilt Angle is Associated with Decreased Gait Speed and Hip Function in Older Patients with Hip Osteoarthritis.

Objectives: This study examined the relationships between preoperative posterior pelvic tilt with muscle strength, gait speed, hip function, and quality of life in older patients with hip osteoarthritis.

Methods: This cross-sectional study included 65 patients with hip osteoarthritis (75.0 ± 10.

Regional cerebral oxygen saturation during initial mobilization of critically ill patients is associated with clinical outcomes: a prospective observational study.

Background: Vital signs help determine the safety of early mobilization in critically ill patients in intensive care units. However, none of these variables directly assess cerebral circulation. Therefore, we aimed to investigate the relationship of regional cerebral oxygen saturation (rSO) and vital signs with in-hospital death in critically ill patients.

Determinants of Longitudinal Changes in Exercise Capacity in Patients With Independent Functioning on Hemodialysis.

Objective: Patients with chronic kidney disease reportedly have decreased muscle oxygen utilization, which most substantially decreases exercise capacity, followed by cardiac reserve. However, determinants of longitudinal changes in exercise capacity in patients on hemodialysis (HD) and the effects of long-term exercise interventions (EI) are unknown. This study was conducted to clarify these concerns.

Leg fidgeting alleviates reduced oxygen extraction in the gastrocnemius muscle caused by prolonged sitting: a randomized crossover trial.

Purpose: Oxygen extraction in skeletal muscle is an important determinant of exercise tolerance. Prolonged sitting decreases oxygen extraction in the gastrocnemius muscle. However, the underlying mechanism remains unknown, and preventive measures are yet to be established.

Acute Effects of Skeletal Muscle Electrical Stimulation on Central and Lower Extremity Hemodynamics.

Introduction: Belt electrode-skeletal muscle electrical stimulation (B-SES) is a treatment prescribed for individuals with difficulty performing exercise therapy that improves muscle strength, exercise tolerance, and glucose metabolism. However, the effects of B-SES on the hemodynamics of the central and lower extremity conduit arteries have not been studied. Therefore, this study compared the acute effects of B-SES on the central and lower extremity conduit arteries in healthy young males.

Associations between bioelectrical impedance analysis-derived phase angle, protein-energy wasting and all-cause mortality in older patients undergoing haemodialysis.

Aim: Protein-energy wasting (PEW) is a common syndrome in patients undergoing haemodialysis (HD) and is associated with poor prognosis. Bioelectrical impedance analysis (BIA)-derived phase angle (PA) is useful for predicting PEW, but sex and age need to be considered. We aimed to reveal sex-specific cut-off values of PA predicting PEW in HD patients aged ≥65.

Transcapillary PO Gradients in Contracting Muscles of Type I Diabetic Rats.

Objective: This study aimed to clarify the effect of Type I diabetes (DIA) on transcapillary PO gradients, which are oxygen-driving factors between the blood and the interstitium, in the contracting muscle of rats.

Methods: Wistar male rats were divided into the diabetic (streptozocin i.p.

Prolonged Sitting Induces Elevated Blood Pressure in Healthy Young Men: A Randomized Crossover Trial.

Introduction Prolonged sitting-induced blood pooling in the lower legs can increase blood pressure through increased sympathetic nerve activity and peripheral vascular resistance, an aspect that has been understudied as a primary outcome. This study compared the effects of prolonged sitting with those of prolonged supination on blood pressure in healthy young men. Methods This randomized crossover study included 16 healthy young men (mean age: 21.

Protein intake and its relationship with frailty in chronic kidney disease.

Introduction: Patients with chronic kidney disease (CKD) are susceptible to frailty because of a range of nutrition-related factors. While protein restriction is commonly advised to preserve kidney function in patients with CKD, insufficient protein intake could potentially exacerbate frailty risk. This study aimed to elucidate the relationship between frailty and protein intake in patients with CKD.

The effect of sepsis and reactive oxygen species on skeletal muscle interstitial oxygen pressure during contractions.

Objective: This study aims to examine the effect of sepsis on the dynamics of skeletal muscle partial oxygen pressure during muscle contractions as well as the effect of reactive oxygen species (ROS) scavenger (ascorbic acid, Asc).

Methods: Twenty-seven male Sprague-Dawley rats (2-3 months old) were randomly assigned to three groups; sham, cecal ligation and puncture (CLP), or CLP plus ascorbic acid treatment group (CLP + Asc). Electrical stimuli-induced muscle contractions and partial oxygen pressure measurements were performed at 3 h after CLP.

Low muscle strength and physical function contribute to falls in hemodialysis patients, but not muscle mass.

Introduction: Patients on hemodialysis (HD) have a higher incidence of fractures than the general population. Sarcopenia is frequently observed in patients on HD; however, the association of falls with sarcopenia and its diagnostic factors, including muscle mass, muscle strength, and physical function, are incompletely understood.

Methods: This prospective cohort study was conducted at a single center.

Relationships between frailty and exercise capacity in patients undergoing hemodialysis: A cross-sectional study.

Aim: Hemodialysis (HD) patients have a high prevalence of frailty. The association between frailty and exercise capacity in HD patients has not been established. This study aimed to clarify the relationships between frailty and exercise capacity in HD patients.

Impact of raising the upper extremity siding cardiac implantable electrical devices on postoperative safety.

Background: The upper extremity siding cardiac implantable electrical device tends to have a limited range of motion during the perioperative period; however, the underlying reason lacks scientific evidence. This study aimed to investigate the safety of the two methods (stepwise or early) of postoperative early upper extremity rehabilitation.

Methods: We retrospectively investigated 650 consecutive patients with a new implantable pacemaker (PM), implantable cardioverter-defibrillator (ICD), cardiac resynchronization therapy (CRT), or generator exchange between March 2017 and December 2020.
