conclusions although we found a trend towards decreasing spah and improving 6mwd, no statistically significant shift were detected in our outcomes due to inadequate sample size. patients and methods a registered (irct201108257411n1), triple-blind, randomized controlled trial was performed in rasoule akram hospital, tehran, from 2009 to 2011. forty five patients with secondary pulmonary hyperten...

Background: Pulmonary rehabilitation is an important part of treatment in patients with COPD (Chronic Obstructive Pulmonary Disease) with the goal of achieving and maintaining maximum functional independence since this disease causes symptoms including fatigue, and consequently decrease in daily living activity. Aim: To determine the effect of home-based pulmonary rehabilitation on daily living...

BACKGROUND It has recently been suggested that people with chronic obstructive pulmonary disease have an increased risk of falls. Although falls risk is multifactorial, impaired balance may contribute. The primary aim of this study was to compare balance between people with and without chronic obstructive pulmonary disease and the secondary aim was to determine if balance deteriorates when resp...

Introduction: Pulmonary hyperinflation in patients with chronic obstructive pulmonary disease (COPD) can increase the breathing rate and reduce diaphragmatic movements by pushing the diaphragms downward and limiting their movements; this, in fact, can affect the breathing process. The purpose of this study was to compare diaphragmatic movements in COPD patients and healthy ones and to evaluate ...

background : sleep apnea is accompanied by some cardiovascular complications. it has even been hypothesized that sleep apnea, itself, can induce some of these complications. given such controversies, we assessed the left ventricular mass index (lvmi) and systolic pulmonary artery pressure in patients with sleep apnea. methods: through convenience sampling, 56 patients with the obstructive sleep...

26 Background: Glucocorticoid function is markedly impaired in the lungs of patients with 27 chronic obstructive pulmonary disease. This reduction in glucocorticoid sensitivity may be 28 due to an oxidant-mediated elevation in phosphoinositol 3-kinase  signaling. 29 Objective: To determine the role of phosphoinositol 3-kinase  in the reduced glucocorticoid 30 responsiveness in chronic obstruc...
