Effects of intradialytic inspiratory muscle training at different intensities on diaphragm thickness and functional capacity: clinical trial protocol in patients undergoing haemodialysis.

Introduction: Patients with end-stage renal disease (ESRD) undergoing haemodialysis (HD) commonly present with a sedentary behaviour and reduced functional capacity, factors that can compromise their prognosis. Intradialytic inspiratory muscle training (IMT) can increase respiratory muscle strength and, consequently, improve functional capacity, besides being easy to apply, cheap and performed in a supervised setting. However, few studies show the effects of this type of training applied at different intensities in this population.

Fibrosing Alopecia in a Pattern Distribution (FAPD) in 16 African-Descent and Hispanic Female Patients: A Challenging Diagnosis.

Background: Fibrosing alopecia in a pattern distribution (FAPD) has only been described in Caucasian patients, and it is not clear whether it can develop in dark-skin ethnicities.

Materials And Methods: Sixteen Brazilian female patients, 12 of African descent and 4 Hispanic, with progressive scarring alopecia in a pattern distribution were analyzed.

Results: Dermatoscopic features showed perifollicular erythema and scaling (14/16), hair fiber diameter diversity (16/16), loss of follicular ostia (16/16), and follicular keratosis (3/16).

Hepatitis B vaccination coverage and postvaccination serologic testing among medical students at a public university in Brazil.

The aim of this cross-sectional study was to determine the hepatitis B vaccination coverage among medical students at a public university in Rio de Janeiro, Brazil, and their compliance with the postvaccination serologic testing recommendations. Of the total of 858 students, 675 (78.7%) participated in the study.

Pandemic influenza A/H1N1 vaccination coverage, adverse reactions, and reasons for vaccine refusal among medical students in Brazil.

The aim of this cross-sectional study was to determine, among medical students at a public university in Rio de Janeiro, Brazil, the acceptance of the pandemic influenza A/H1N1 vaccine during the 2010 mass immunization campaign and the vaccine safety in this group and, among unvaccinated students, the reasons for refusing vaccination. Of a total of 858 students, 678 (79%) participated in the study. Vaccination coverage was 60.
