Active clinical trials for "Lung Diseases"

Chronic airways diseases involve alterations in the person's social roles, relationships and self-perception so demands continual psychological adjustment . Also Kunik studied patients with chronic breathing disorders for depression and anxiety and found that 65% of patients were positive for depression and anxiety. Shackell found that patients' anxiety and fears of breathlessness and dying extended into the night and were aggravated by feelings of isolation and frustration. One patient reported that they often thought 'am I going to see the next morning?'

The aim of this study is to assess the perception of chronic obstructive pulmonary disease (COPD) patients in symptoms related to morning activities. Also the researchers investigated how to describe the impact of symptoms on sleep quality and how to use the medication in Korea COPD treatments.

Some patients with chronic obstructive pulmonary disease (COPD) need supplementary oxygen during air travel. Guidelines issued by The British Thoracic Society (BTS) for pre-flight evaluation do not discriminate sufficiently between those who need supplementary oxygen during flight, and those who can do without. Previous studies have indicated that decreasing hemoglobin oxygen saturation during exercise may predict in-flight hypoxemia. The objective of the present study is to examine if adding exercise oxygen desaturation to the BTS algorithm will better predict requirements for in-flight supplementary oxygen.

The purpose of this study is to compare in home support services for patients with COPD with usual care. The study is designed to evaluate the impact of an interdisciplinary palliative care team on community based self management of advanced COPD. A total of thirty patients will be enrolled into this study. Twenty patients will be randomly assigned to receive usual care, and ten patients will be randomly assigned to usual care plus in home support services. This study will use objective criteria to identify patients with COPD likely to benefit from home based palliative care services. The patients will undergo initial assessment by medical, social work, and spiritual care personnel followed by a family meeting to establish a care plan. Periodic scheduled visits, and as needed unscheduled visits to address urgent needs will occur over one year's time in an attempt to return patients with COPD to the center of decision making regarding their care, avoid acute exacerbations and thereby avoid unscheduled clinic and ER visits. Patients will complete the QOL survey and symptom assessment scale upon initial intervention. After obtaining information from all patients who qualify for the study, participants will be randomized into cohorts. Those who are randomized to serve as cases will be provided with community based self management services by an interdisciplinary palliative care team. The control group will receive standard care. At the conclusion of 12 months both cases and controls will again complete the QOL survey,medical utilization, and symptom assessment.

The purpose of this study is to evaluate how easily gas can be taken up by the lung. We are comparing infants born premature <32 weeks gestation to infants born full term >37 weeks. We hope to evaluate the differences between the two groups in order to learn more about premature lung growth and development.

Obstructive lung disease is usually a differential diagnostic consideration when a patient presents with breathlessness or cough. Spirometry is the key diagnostic test used to confirm airflow obstruction particularly in the primary care setting. Airflow obstruction that completely resolves after administration of a bronchodilator, by definition, excludes a diagnosis of COPD. Evaluation of obstructive lung disease must include pulmonary function testing; bronchoreversibility testing is an adjunct in differentiating between asthma and COPD. Bronchoreversibility cannot serve as an absolute diagnostic criterion for separating asthma from COPD. Vibration response imaging (VRI) technology provides a simple, radiation-free method to image the lungs, by visualizing vibration energy (lung sounds) emitted during respiration cycle. In this study, regional quantitative and qualitative information on vibration response is compared with spirometry in assessing lungs function of COPD and Asthma patients.

The main objective of the study is to evaluate the predictive factors of the endothelial function to the waning of an acute exacerbation in COPD. It will act to do a multivariate analysis to determine the respective weight of the parameters of the systemic inflammation, of the oxidative stress of the functional respiratory parameters and then functional respiratory parameters. In exacerbated Chronic Obstructive Pulmonary Disease (COPD) patients, there is augmentation of hypoxia and the obstructive ventilatory disorders is more important. This is correlated with an increase in C-reactive Protein (CRP) and of inflammatory cytokines and oxidative stress. It has been demonstrated that there is an endothelial dysfunction in answer to hypoxia. Since the exacerbated COPD patients are hypoxic in most cases , we suppose they have an endothelial dysfunction during exacerbation. So we think we will find an augmentation of vascular resistances ,shown by a peripheral arterial tone too high. And this, certainly, play a part in physiopathology of the COPD exacerbation.

To evaluate asthma morbidity in low-income, African-American children and adults with asthma.

The purpose of this protocol is to obtain biologic samples from the blood and lungs from patients with lung diseases in order to study the causes and indications of these disorders, learn how these lung disease manifest and progress, and how the lung disease can be treated.

This research seeks to establish a neonatal DNA Tissue Bank to find out if differences in small segments of DNA predispose babies to Chronic Lung Disease (CLD), Periventricular Brain Injury (PVI), Necrotizing Enterocolitis (NEC), or Hypoxic Respiratory Failure (HRF).
