Reliability and validity of the Patient Generated Index (PGI) in patients with chronic kidney disease (CKD) on dialysis, a new approach to quality of life.

Purpose: To evaluate the test-retest reliability and validity of the Patient Generated Index (PGI) in individuals with Chronic Kidney Disease (CDK) undergoing hemodialysis.

Methods: Through a non-experimental study with repeated measures, PGI was applied twice to assess internal consistency and test-retest reliability. Correlations with the Kidney Disease Quality of Life Short Form (KDQOL-SF), the Human Activity Profile (HAP) questionnaire, the Social Participation Scale, and the Glittre ADL Test were used.

Efficacy of Acupuncture on Quality of Life, Functional Performance, Dyspnea, and Pulmonary Function in Patients with Chronic Obstructive Pulmonary Disease: Protocol for a Randomized Clinical Trial.

Chronic obstructive pulmonary disease (COPD) is a respiratory disease characterized by the presence of chronic airflow obstruction. Previous studies have evaluated the effect of acupuncture treatment (AT) in patients with COPD. Nevertheless, these studies show a great deal of heterogeneity in treatment protocols, having sample sizes that are too small to estimate and clarify effect size and heterogeneity in patients' baseline.

Objective: To determine the cardiorespiratory and metabolic demand of the Six-Minute Pegboard and Ring Test (6PBRT) in healthy young adults and its association with maximal arm cycle ergometer test (arm CET).

Methods: Volunteers were randomized to performed the 6PBRT test or arm CET. The second test was performed after 48 h.
