Active clinical trials for "Lung Diseases"

The aim of this study is to estimate level of IL 6 in COPD patients and its relation to COPD severity and acute exacerbation.

THRIVE and iGEL were applied for maintain oxygenation in bronchoscopic interventions which could not performed with an endotracheal tube. However, besides the risk of desaturation, the differences on difficulties to approach vocal cords, the responses to spay of local anesthetics including cough or spasm, the CO2 elimination, the hemodynamic changes, and the effects on postoperative recovery are rarely investigated.

Textile workers are exposed to various harmful substances during work, including cotton dust, which is the dust present in air during the handling or processing of cotton. Previous research found a link between cotton dust exposure and impaired respiratory health. This study will comprise of administration and workers' training regarding preventive measures for protection against respiratory illnesses. Workers will be provided free, disposable face masks and measures to reduce cotton dust exposure will be introduced at the textile mills. The study would then determine the effectiveness of this intervention on reduction in cotton dust levels in the mills, and improvement in respiratory health of workers. This study would help the cotton textile workers and managers reduce the health hazards of cotton dust exposure and also guide researchers from Pakistan and other low-resource countries towards developing relevant strategies for health protection of these workers.

The present study is to evaluate the effect of positive end-expiratory pressure (PEEP) in predicting fluid responsiveness in patients undergoing one-lung ventilation.

The purpose of this study is to prospectively assess the efficacy and safety of spray cryotherapy ablation with the truFreeze System in conjunction with mechanical dilation or debridement for the treatment of clinically significant obstructions of the central airways. The primary effectiveness endpoint is the proportion of subjects with a minimum of 25% improvement in luminal patency following SCT treatment and mechanical intervention 30 days (+/- 5 days) following treatment. Additionally, a primary clinical safety endpoint is the reporting of all adverse events.

The purpose of this study is to evaluate the efficacy of clarithromycin in eradication of ureaplasma urealyticum and prevention of chronic lung disease in premature infants with birthweight < 1250 g and have ureaplasma urealyticum colonization.

Highly active antiretroviral therapy (HAART) has considerably improved survival of HIV-infected patients. Opportunist diseases and cancers linked to immunodepression have largely regressed. Challenge is now the management of cardio-vascular diseases, nephrologic, neurologic, osteo-articular diseases, chronic hepatitis and cancer no linked to immunodepression. All this comorbidities are more reported in HIV-infected patients than in general non-HIV infected patients. Those are directly linked to the effect of chronic HIV-infection on ageing, metabolic effects of HAART, and way of life characterising this population. Chronic obstructive pulmonary disease (COPD) results from tobacco consumption. Bronchial chronic infection, immunity, and ageing are also involved in the physiopathology of COPD. This disease has never been evaluated in a large prospective cohort of HIV-infected patients whereas there is a known increase of tobacco consumption and pulmonary infection in this population regardless to the general population. Characterisation of COPD disease in HIV patients will allow us to make an hypothetic epidemiological link between HIV- HAART and COPD independently of tobacco consumption, and to study different physiopathologic hypothesis evocated in COPD genesis, like an accelerate pulmonary ageing.

The purpose of this study is to determine if real-time feedback (lights/sounds) from small smoke particle monitors and brief coaching will encourage parents to reduce young children's secondhand tobacco smoke exposure in their home.

The objective of this study is to evaluate the safety and effectiveness of the RePneu Lung Volume Reduction Coil (LVRC) in patients with Alpha-1-Antitrypsin deficiency (AATD) caused emphysema. The hypothesis is that emphysema in AATD patients shows similar tissue destruction profile was well as symptoms and thus will respond favorably to LVRC treatment, demonstrating improvement in lung function, exercise capacity, and quality of life relative to their baseline status.

Several studies and registries suggested that the concomitant presence of acute coronary syndromes (ACS) and chronic obstructive pulmonary disease (COPD) is significantly associated with poor prognosis. It has been suggested that diagnosis of COPD is frequently missing. Thus, it is plausible that a significant percentage of patients with ACS may have unrecognized COPD. This missing diagnosis may contribute significantly to poor prognosis. The investigators suppose that the concomitant use of peak expiratory flow (PEF) measurement and of Respiratory Health Screening Questionnaire (RHSQ, adapted version) could be useful as screening test for COPD in patient smokers or former smokers admitted to hospital with a diagnosis of ACS. In all screened patients COPD diagnosis will be confirmed (or not) two months after hospital discharge with spirometry. In the same setting of patients, the investigators will characterize the underlying pathological mechanisms, evaluating several inflammation, platelet and endothelial markers.
