Filter by:Primary objective: The aim of this study is to determine the efficacy and safety of five days of oral corticosteroids (40 mg / day) for the treatment of acute exacerbations of COPD (AECOPD) in outpatients.
Hypothesis;Aging modifies the risk of pulmonary dysfunction in HIV+ individuals. The study is a multicenter, prospective observational study of aging and pulmonary function in HIV. The investigator will determine the prevalence and risk factors for lung dysfunction as quantified by pulmonary function testing in both younger (<50 years) and older (≥50 years) HIV+ and HIV-uninfected controls. The investigator will build on existing cohorts and enrich enrollment for individuals over the age of 50 while adjusting for important co-variates such as ART, smoking history, co-infections, and illicit drug use. Evaluations will be scheduled at baseline, 18 months, and 36 months. Study visits will consist of blood draw, questionnaires, and pulmonary function testing.
Use of a microfabricated silicon device to concentrate ultra trace volatile organic compounds (VOCs) in human exhaled breath for quantitative analysis of VOCs.
The objective of the study is to evaluate the reliability of the impedance data in adult subjects measured with five different FOT devices.
The objective of this clinical study is to evaluate the safety of the Progel® PALS, including the Progel® Extended Applicator Spray Tips, in sealing or reducing intraoperative air leaks in patients undergoing video assisted or robotic assisted thoracoscopic (VATS/Robotic) surgeries. The data collected in this clinical study will supplement the Approved PMA P010047 Progel® PALS product.
Peak Inspiratory Flow Rate (PIFR) is defined by the fastest flow rate noted during the inspiratory cycle. Inhaled medication plays an important role in the treatment of chronic obstructive pulmonary disease (COPD), with dry powder inhalers (DPIs) increasingly replacing metered dose inhalers (MDIs). DPIs are interesting as they do not require the need for coordinate actuation of the MDI device with inhalation or the use of a large spacer device 1-3. Several DPIs are available for the administration of inhaled corticosteroids, as well as bronchodilators, with each of them corresponding to a different type of inhaler (e.g. Diskus®, Turbuhaler®, Aeroliser®, etc.). During the inspiratory effort the patient generates a pressure drop with a consequent airflow across the DPI. This inspiratory flow has to be high enough to disaggregate and adequately disperse the drug powder into an aerosol cloud of drug particles and to guarantee an optimal deposition of the medication in the lung. Such peak inspiratory flows (PIFs) are not only dependent on a patient's inhalation effort but also on the internal resistance of the device. It has been shown that optimal deposition of medication with DPIs is not achieved in some patients with low inspiratory flow rates, such as children or patients with COPD, especially during acute exacerbations. In such conditions the use of a DPI with low internal resistance has been suggested, ensuring an optimal deposition despite the lower flow rate. In addition, many clinicians are nowadays confronted with an important number of COPD patients who are aged >70 yrs
To determine if stair climbing can be used as a measure of progress in persons with pulmonary disease.
Background: - Some premature babies develop bronchopulmonary dysplasia (BPD) and retinopathy of prematurity (ROP). BPD and ROP are long-term chronic diseases of the lungs and eyes, respectively. BPD is associated with receiving mechanical ventilation to treat respiratory distress syndrome, and causes lung inflammation and scarring. ROP is caused by poor development of blood vessels in the eyes, and may lead to blindness. Because not all premature babies develop BPD or ROP, researchers want to study the genes that could be associated with these diseases. They will look at both premature infants and their parents to see if there is a genetic component to BPD and ROP. Objectives: - To study genes that may be associated with BPD and ROP. Eligibility: - Premature babies born with a weight less than or equal to 1,250 grams. - Parents of the premature babies. Design: - Parents will answer questions about the mother s health and pregnancy. - Delivery and medical information will be collected during the baby s hospitalization for the first month after birth. - Parents will provide a saliva sample from the inside of the cheek. - A saliva sample will also be collected from the baby within 28 days of birth. If the baby needs tracheal aspiration (removal of fluid from the throat), tracheal fluid samples will also be collected. - Parents will have followup interviews about their child s health 6 months, 12 months, and yearly for up to 6 years after birth. - This is a genetic study only. Treatment will not be provided as part of this study.
Informal caregivers provide a majority of care for patients at the end of life. Lack of end of life preparation and completion may leave caregivers less capable of caring for a loved one or making crucial decisions influencing care. This study will examine whether a preparation and completion intervention reduces caregiver anxiety, depression, anticipatory grief, and burden and improves patient quality of life and health care use
Pulmonary hypertension (PH) can be the result of various clinical conditions. It may be idiopathic or associated with various cardiovascular and lung disorders. Currently there is no test that can non-invasively detect abnormalities of the pulmonary circulation. There is a growing need for a non-invasive method to detect PH. There currently exists only ne agent approved in Canada for clinical imaging of the pulmonary circulation, 99mTc-labeled macroaggregates. This agent is exclusively used for the diagnosis of physical defects of the circulation due to pulmonary embolus. This agent is larger than small pulmonary vessels, limiting its sensitivity to detect small vascular defects, as well as potential infectious risks since albumin macroaggregates are derived from human albumin. There is need then for new lung tracers that could provide a greater safety profile while enabling functional as well as anatomical imaging of the pulmonary circulation. DFH-12 (PulmoBind) is a peptide derived from human adrenomedullin (hAMI-52). Hence the development of this novel AM derivative, PulmoBind, for molecular imaging of the pulmonary circulation. PulmoBind is labeled with 99mTc, the most commonly used imaging isotope in nuclear medicine.
