Introduction: The forced expiratory flow at 25 and 75% of the pulmonary volume/forced vital capacity ratio (FEF25-75/FVC) as a spirometry parameter has been successful in the early diagnosis of chronic obstructive pulmonary disease (COPD) and the methacholine challenge test for assessing airway responsiveness.To determine the accuracy of FEF25-7...
However the effects of endurance training on respiratory system is approved somedeal but, few and contradictory evidence exist concerning resistance training (RT), so the purpose of this research was therefore to study effects of eight weeks circuit RT (CRT) on pulmonary function of inactive women. Nineteen volunteer healthy inactive women were randomly divided into 2 groups: without tra...
We have read with interest the article by HANSEN et al. [1] in a recent issue of the European Respiratory Journal, stating that the use of forced expiratory volume in six seconds (FEV6) reduces the sensitivity of obstructive lung disease detection. Their study population of 3,515 current smokers, with a 17.5% prevalence of obstruction, found a sensitivity of only 76.8% and a specificity of 98.2...
OBJECTIVE To explore the backpack load as a percentile of body weight (BW) and its impact on ventilatory function including tidal volume (Vt), vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), FEV1/FVC, peak expiratory flow (PEF), and maximum voluntary ventilation (MVV) among 9-12 year old Saudi girls. METHODS This is a prospective, experimental ...
This study was conducted to investigate the prevalence of pulmonary problems, among a group of 1600 selected textile mill workers in the Yazd province. A standard questionnaire on respiratory symptoms was administered and forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) were determined for each worker. The results obtained were as follow: Obstructive ventilatory def...
Objective: To evaluate pre and post-operative spirometry in patients with tuberculosis sequelae undergoing lobectomy. Methods: We selected 20 patients, aged between 15 and 56 years, of both genders, with a history of tuberculosis treatment, with repeated infections or hemoptysis and indication of pulmonary lobectomy. The tuberculosis treatment time was six months, and onset of symptoms, between...
Vitamin D has several extra calcemic effects. Vitamin D deficiency is highly prevalent in chronic obstructive pulmonary disease (COPD) patients but little is known about it's association with lung function. OBJECTIVE To investigate whether supplementation with vitamin D could improve pulmonary function in COPD patients. DESIGN Before and after, double center, clinical trial. SETTING Hazra...
BACKGROUND The treatment landscape for idiopathic pulmonary fibrosis, a devastating lung disease, is changing. To investigate the effectiveness of treatments for idiopathic pulmonary fibrosis we undertook a systematic review, network meta-analysis and indirect comparison. METHODS We searched MEDLINE, EMBASE and The Cochrane library for relevant studies. Randomised controlled trials of pirfeni...
