Persistence of symptoms and lung function in mild cases of COVID-19 six months after infection: a cross-sectional study.

Objectives: To describe persistent symptoms and lung function in mild cases of COVID-19 six months after infection.

Methods: Data collection was performed through a semi-structured questionnaire containing information on the participants' demographic and anthropometric data, the disease in the acute phase, and persistent symptoms six months after COVID-19 using spirometry and manovacuometry.

Results: A total of 136 participants were evaluated, of whom 64% were male, with a mean age of 38.

Correlation between functional capacity and oxidative stress and inflammation in hemodialysis patients.

Introduction: Patients with chronic kidney disease (CKD) may present impaired functional capacity due to peripheral muscle involvement. Oxidative stress and inflammation are probably involved in this pathophysiology. This study aimed to evaluate the association between functional capacity and biomarkers of oxidative stress as well as biomarkers of inflammation in patients under chronic hemodialysis therapy.

Effects of respiratory muscle training on endothelium and oxidative stress biomarkers in hemodialysis patients: A randomized clinical trial.

Introduction: Hemodialysis (HD) patients have altered pulmonary function and this is associated with impaired endothelial function and cardiovascular events. Respiratory muscle training (RMT) has the potential to improve cardiovascular outcomes in patients undergoing maintenance HD. Here, we evaluated the effects of RMT on endothelium/glycocalyx, oxidative stress biomarkers and pulmonary function test in HD patients.
