Clinical, Analytical, and Echocardiographic Associations of Impaired Cardiorespiratory Fitness After Anthracycline Chemotherapy in Breast Cancer: EPIC Fitness Study.

Purpose: This study explores the effects of anthracycline chemotherapy (AC) on breast cancer patients, focusing on changes in body composition, advanced echocardiographic parameters at rest and during exercise, and biomarkers; and subsequently assesses whether these parameters are associated with impaired cardiorespiratory fitness (CRF).

Methods: In this prospective study, we evaluated women with early-stage breast cancer undergoing AC at three visits: before AC, 1 month after, and 6 months post-AC.

Results: The study included 32 women with breast cancer, with functional disability increasing from 9.

Ghostly intrusion on a frightful Halloween night: a case report of dual valve endocarditis.

Multivalvular endocarditis (MVE) is an uncommon presentation and mostly involves mitral and aortic valves. Here, we present a case of an MVE with an unusual and bizarre presentation on a Halloween night with a massive degree of valve destruction and right- and left-side involvement requiring emergent surgery. A 51-year-old male patient with intravenous drug usage presented with anorexia, fever, and dyspnea, rapidly progressing to septic shock with multiorgan dysfunction.

COVID-19 on patients with immune-mediated rheumatic disease: a comparative study of disease activity, fatigue, and psychological distress over six months.

Objectives: To compare the impact of COVID-19 on the clinical status and psychological distress of patients with immune-mediated rheumatic disease (IMRD) caused by SARS-CoV-2 infection with that of noninfected IMRD controls during a 6-month follow-up period.

Methods: The ReumaCoV Brazil is a longitudinal study designed to follow IMRD patients for 6 months after COVID-19 (patients) compared with IMRD patients without COVID-19 (controls). Clinical data, disease activity measurements and current treatments regarding IMRD and COVID-19 outcomes were evaluated in all patients.

Silica-exposed patients with silicosis show shorter telomeres than do unexposed individuals: a pilot study in a population in southeastern Brazil.

Objective: Silicosis is a pneumoconiosis characterized by fibrosis of the lung parenchyma caused by the inhalation of silica particles. Silica dust inhalation is associated with inflammation and induction of oxidative stress in the lungs. This oxidative stress affects telomeres, which are short tandem DNA repeats that cap the end of linear chromosomes.
