Active clinical trials for "Lung Diseases"

To determine the incidence of tuberculosis in an inner city population, identify risk factors for TB, describe the natural history in adults and children, evaluate the effect of Mycobacterium tuberculosis (Mtb) co-infection on the progression of human immunodeficiency virus disease, and determine factors that contribute to compliance and non-compliance with prophylaxis and treatment.

To identify risk factors for work disability among adults with asthma treated by pulmonary and allergy specialists.

To establish a registry of individuals with LAM by forming a consortium of six clinical centers and referring physicians who treat LAM patients.

Ozone is an air pollutant formed in at ground level by the chemical reaction between oxygen and automobile emissions in the presence of sunlight. The objective of this research is to determine how lung size, chemical composition, and normal functioning of the respiratory system affect the amount of inhaled ozone that reaches internal sites of tissue irritation and damage. To infer the distribution of inhaled ozone within the respiratory system, measurements of ozone concentration and air flow are made just outside the nose and mouth of healthy subjects who breathe laboratory-generated, ozonated air for about one hour. Biochemical composition of respiratory mucus is then inferred from nasal washings made with salt water. The amount of ozone that a subject retains in one of these experiments is less than the daily exposure in a large city such as New York or Los Angeles.

Chronic obstructive pulmonary disease (COPD) is one of the most common chronic illnesses among veterans in the adult population, and accounts for substantial morbidity and mortality in this population. Interventions that enhance symptom self-monitoring and increase understanding of COPD therapy may lead to earlier detection of clinical deterioration permitting more timely intervention by health care providers. However, such interventions are labor-intensive and expensive, and typically require patients to go to a medical facility on a regular basis. A novel means of providing such interventions is a Telephone-Linked Computer (TLC) system, a computer-based telecommunications system that can monitor, educate, and counsel patients through regular automated conversations in patients� homes. In previous studies, we have demonstrated the applicability of TLC technology in the clinical monitoring of adults with chronic disease conditions such as hypertension and hypercholesterolemia.

This prospective study intends to development and validation a patient self-assessment questionnaire. The aim of the self-assessment, by questionnaire, is to estimate the risk of postoperative pulmonary complications (PPC).

It has been reported that nearly half of the patients who are hospitalized for Covid-19 pneumonia have on admission old age or comorbidities. In particular, hypertension was present in 30% of the cases, diabetes in 19%, coronary heart disease in 8% and chronic obstructive lung disease in 3% of the patients. Amazingly, in the two major studies published in the Lancet (Zhou F et al Lancet 2020) and in the New England Journal of Medicine (Guan W et al 2020), the weight of the subjects as well their body mass index (BMI) were omitted. However, obesity, alone or in association with diabetes, can be a major predisposition factor for Covid-19 infection. The primary end-point of our prospective, observational study is to assess the recovery rate in patients with diagnosis of Covid-19 pneumonia. Among the other secondary end-points, we intend to find the predictors of the time to clinical improvement or hospital discharge in patients affected by Covid-19 pneumonia.

To investigate the relation the nreural drive and intrinsic positive end-expiratory pressure(PEEPi) of the chronic obstructive pulmonary disease(COPD) patients with respiratory failure.In present study the PEEPi of COPD patients was increased by increasing the resistance of the respiratory system, the change of the neural drive was recorded.

This is a qualitative research exploration engaging clinical staff at all levels from 10 Practice-Based Research Networks (PBRNs) serving US patient populations of differing gender, racial, ethnic, urban/rural and socio-economic blends, in the incorporation of a one-page, five-item questionnaire with selective PEF measurement (CAPTURE).

The rationale for this non-interventional study in confirmed moderate to severe chronic obstructive pulmonary disease patients aged 40 years and above, is to assess real-life effectiveness and safety of Trimbow® in clinical practice, and to bridge the gap with the existing clinical data.
