Multicenter Study
Opium could be considered an independent risk factor for lung cancer: a case-control study.
Lung cancer is the leading cause of cancer-related death worldwide, and half of all incident lung cancers are believed to occur in the developing countries, including Iran. ⋯ This study demonstrated that smoking opium is associated with a high risk of lung cancer as an independent risk factor.

Acute respiratory distress syndrome (ARDS) is a pulmonary syndrome with growing prevalence and high mortality and morbidity that increase with age. There is no current therapy able to restore pulmonary function in ARDS patients. ⋯ Recent studies have demonstrated that MSCs can also control oxidative stress, transfer functional mitochondria to the damaged cells, and control bacterial infection by secretion of antibacterial peptides. These characteristics make MSCs promising candidates for ARDS therapy.

Water pipe is a traditional method of tobacco use, which is epidemically spreading throughout Europe. There are scarce data about the use of water pipe and its relation to other addictive behaviors among young adults in Western countries. ⋯ Water pipe smoking is common among young adults and strongly associated with cigarette smoking and cannabis consumption.

Breathing pattern description and chest wall kinematics during phonation have not been studied in male and female patients with chronic obstructive pulmonary disease. ⋯ Phonation imposes more abdominal breathing pattern changes in males and costal changes in females. Expiratory flow encroaches upon the MEFV curve with higher phonatory efforts and respiratory discomfort.

Multicenter Study Comparative Study
Exertional desaturation as a predictor of rapid lung function decline in COPD.
To date, no clinical parameter has been associated with the decline in lung function other than emphysema severity in COPD. ⋯ This study suggests, for the first time, that exertional desaturation may be a predictor of rapid decline in lung function in patients with COPD. The 6MWT may be a useful test to predict a rapid lung function decline in COPD.
