Exercise intolerance and malnutrition associated with all-cause mortality in elderly patients undergoing peritoneal dialysis: a single-center prospective cohort study.

Background: Low physical function and malnutrition in elderly patients undergoing peritoneal dialysis (PD) are important issues that may be associated with prognosis. We aimed to determine the association between physical function and nutritional status and survival in elderly patients undergoing PD.

Methods: This single-center, prospective cohort study included 45 stable, ambulatory patients undergoing PD.

Effects of cognitive impairment and assisted peritoneal dialysis on exit-site infection in older patients.

Background: Elderly peritoneal dialysis (PD) patients required assistance for a variety of PD-related tasks. The usefulness of assisted PD in reducing the peritonitis risk has been reported; however, there is little evidence on the effectiveness of assisted PD in preventing exit-site infections in older patients.

Methods: This was a single-center, prospective cohort study.

Predicting a target exercise heart rate that reflects the anaerobic threshold in nonbeta-blocked hemodialysis patients: The Karvonen and heart rate reserve formulas.

The aim of this study was to evaluate constants of the Karvonen (k) and heart rate reserve (HRR) (α) formulas that correspond to the anaerobic threshold (AT) to conveniently estimate the intensity of exercise therapy in nonbeta-blocked patients undergoing hemodialysis. Twenty-three patients undergoing hemodialysis performed cardiopulmonary exercise testing (CPX) and their HR at AT was measured. The predictor coefficients for a target HR corresponding to AT were calculated for each patient based on CPX.

Relationship Between Psychological Factors and Wound Occurrence in Patients With Peripheral Arterial Disease in the Leg.

This prospective study investigated psychological factors affecting wound healing in patients with peripheral arterial disease (PAD). Fifty patients with PAD in a local hospital were enrolled. The Geriatric Depression Scale short version, Type-D scale 14, Medical Outcome Study 36-Item Short-Form Health Survey (SF-36), Functional Independence Measure, Self-efficacy for Managing Chronic Disease Scale, Barriers Self-Efficacy Scale, and Mini Nutritional Assessment were applied to assess physical and psychological factors.
