Granulomatosis with polyangiitis (GPA) is a systemic vasculitis that can lead to persistent pain and fatigue, significantly impacting patients' quality of life. This study assessed the effects of transcranial direct current stimulation (tDCS) combined with aerobic exercise as a non-pharmacological intervention for managing fatigue in GPA patients. Two patients were randomly assigned to receive either active tDCS or simulated tDCS stimulation (sham) during low-intensity aerobic exercise.

Ethnopharmacological Relevance: The Cissus gongylodes has traditionally been used in the diet of indigenous people in Brazil and in traditional medicine for kidney stone removal and inflammatory diseases. The active compounds responsible for these pharmacological activities are unknown.

Aim Of The Study: This study aims to isolate, for the first time, the compounds in the decoction of C.

Article Synopsis
  • The study aimed to determine if muscle strength in the lower limbs after surgery could predict long-term success (36 months) in patients who underwent Roux-en-Y gastric bypass (RYGB).
  • Muscle strength was measured at three points: before surgery, six months after, and 36 months after, with 123 patients initially and 79 at the final measure.
  • Results showed that increasing muscle strength in the lower limbs by at least 4 Nm/kg at six months was linked to about a 76% chance of surgical success by 36 months.

Context: Transtibial Amputation (TA) predisposes to a sedentary lifestyle.

Objectives: To evaluate the efficiency of a short-term (8-week) Concurrent Training (CT) program in Unilateral Transtibial Amputees (UTA) and to compare it with the physical condition of a group of Paralympic athletes in preparation for the Rio de Janeiro Paralympics.

Design: This was a longitudinal, prospective and controlled trial study.

Objective:: The aim of our study was to evaluate associations between maximum voluntary contraction torques of the lower limbs and body composition for subjects with severe obesity.

Methods:: Body composition was evaluated by bioelectrical impedance analysis, and maximum voluntary contraction torques of the lower limbs were measured using an isokinetic dynamometer. One hundred thirty-two patients were enrolled (100 females and 32 males).

Article Synopsis
  • The study assessed different methods for determining lactate threshold in endurance runners with varying training levels (highly trained vs. lowly trained).
  • Twenty-seven male runners underwent a treadmill test with blood lactate analysis to evaluate their thresholds using three methods: DT1, 4 mmol/l, and semi-log.
  • Results showed that highly trained athletes had higher lactate thresholds, and the 4 mmol method yielded lower results compared to DT1 and semi-log, particularly in lowly trained runners.

Background: Obesity is associated with mobility reduction due to mechanical factors and excessive body fat. The six-minute walk test (6MWT) has been used to assess functional capacity in severe obesity.

Objective: To determine the association of BMI, total and segmental body composition with distance walked (6MWD) during the six-minute walk test (6MWT) according to gender and obesity grade.

Objective: The purpose of this study was to compare aerobic function [anaerobic threshold (%VO(2)-AT), respiratory compensation point (%VO(2)-RCP) and peak oxygen uptake (VO(2)peak)] between physically active patients with HIV/AIDS and matched controls and to examine associations between disease status, poor muscle strength, depression (as estimated by the profile of mood states questionnaire) and the aerobic performance of patients.

Methods: Progressive treadmill test data for %VO(2)-AT (V-slope method), RCP and (VO(2)peak) were compared between 39 male patients with HIV/AIDS (age 40.6 ± 1.

Lymphocyte and neutrophil death induced by exercise and the role of hydrolyzed whey protein enriched with glutamine dipeptide (Gln) supplementation was investigated. Nine triathletes performed two exhaustive exercise trials with a 1-week interval in a randomized, double blind, crossover protocol. Thirty minutes before treadmill exhaustive exercise at variable speeds in an inclination of 1% the subjects ingested 50 g of maltodextrin (placebo) or 50 g of maltodextrin plus 4 tablets of 700 mg of hydrolyzed whey protein enriched with 175 mg of glutamine dipeptide dissolved in 250 mL water.
