Lung function of patients hospitalized with COVID-19 at 45 days after hospital discharge: first report of a prospective multicenter study in Brazil.

Objective: Because SARS-CoV-2 infection can severely affect the lungs and persistent functional changes can occur after severe disease, we aimed to determine lung function parameters of COVID-19 patients at 45 days after hospital discharge and compare changes according to the severity of the disease.

Methods: This was a prospective descriptive analytical multicenter study. The participants were allocated into three groups: ward admission (WA) group; ICU admission not on mechanical ventilation (ICU/MV-) group; and ICU admission on MV (ICU/MV+) group.

Coagulum pyelolithotomy "revisited" by laparoscopy: technique modification.

Objective: Laparoscopic ureteropyeloplasty is a widely accepted treatment option for the obstructed ureteropelvic junction (UPJ). Although it is often a straightforward surgical procedure, there may be technical difficulties in the case of concomitant stone burden, with multiple calicial, small, mobile stones. The authors describe a modification to the classic coagulum pyelolitothomy, using a mixture based on commercially available fibrin sealant, first used in the laparoscopic era.

Metabolic syndrome and sexual (dys)function.

Introduction: The general worldwide increase in metabolic syndrome (MS) among most populations may result in more individuals with sexual dysfunction.

Aim: To provide an update on clinical and experimental evidence regarding sexual dysfunction in patients with MS from both sexes and treatment modalities.

Methods: A comprehensive literature review was performed using MEDLINE with the MeSH terms and keywords for "metabolic syndrome,""obesity,""female sexual dysfunction,""erectile dysfunction,""androgen deficiency,""weight loss," and "bariatric surgery.
