26 Clinical Trials for Various Conditions
This is an unblinded pilot study to investigate the technical feasibility of using an electrical impedance tomography device for noninvasive pulmonary function monitoring in ALS patients. The study will enroll patients with ALS in one cohort and healthy volunteers in a second cohort that will both undergo EIT imaging with the investigational device prior to and while performing a standard PFT procedure.
Comparison of respiratory outcomes in patients receiving telemedicine-guided remote pulmonary function testing (rPFT) with or without the additional support of nurse coaching. This is a randomized controlled study which assesses the effects rPFT and coaching on respiratory outcomes and quality of life.
The specific objective of this study is to validate the practice of remote pulmonary function testing (rPFT) conducted in the home through the use of connected mobile health devices and the Penn State Hershey ALS Telemanagement program.
The primary aim of this study is to quantify and compare changes in lung volumes (as measured by functional residual capacity) in premature infants stable on continuous positive airway pressure (CPAP), and then randomized to two additional weeks of CPAP and room air versus room air alone. We hypothesize that infants randomized to additional CPAP will demonstrate an increased functional residual capacity (at the end of the two week study period and prior to discharge) compared to those randomized to room air.
To implement a new method of performing chest CT imaging in young children at Packard Children's Hospital entitled controlled ventilation infant/young child chest CT scanning. This technique will be used to evaluate early lung disease comparing quantitative chest CT air trapping and airway measurements with lung function measurements in infants, toddlers, and young children with chronic lung disease.
RATIONALE: Measuring how well the lungs work in patients with cancer may help doctors predict how patients will respond to treatment and help plan the best treatment. PURPOSE: This clinical trial is studying lung function testing in patients with locally advanced or metastatic solid tumors.
One course of steroids given to a mother before a premature delivery helps the lungs of the premature infant and decreases breathing problems. One course of antenatal steroids is the standard of care for threatened premature deliveries. It is unclear as to how long the benefit of one course of steroids last. The most benefit to the baby's lungs seem to occur if the steroids are given at least 24 hours before but within 7 days of a premature delivery. It is difficult to predict the timing of a preterm delivery so deliveries often do not occur within this time period. We hypothesize that the benefits of the steroids to the lungs wear off if the steroids are given more than 14 days before a preterm delivery, and that in these circumstances an extra course of steroids will help the premature baby's lungs and the premature baby will have less breathing problems as shown by lung function testing.
Electrical Impedance Tomography (EIT) is a non-invasive imaging technique that can measure lung function in real time. This study will follow premature infants to see if EIT can help predict which infants will be successful in weaning off respiratory support by 32-33 weeks gestational age. If successful, EIT could be used to develop new guidelines for respiratory support in premature infants.
The overall aims of this protocol are to determine whether prenatal supplementation with vitamin C to pregnant smokers can improve pulmonary function at 10 years of age in their offspring. This is an additional continuation of the Vitamin C to Decrease Effects of Smoking in Pregnancy on Infant Lung Function (VCSIP) trial, to follow the offspring through 10 years of age. The hypothesis for this protocol is an extension of the VCSIP trial that supplemental vitamin C in pregnant smokers can significantly improve their children's airway function tests. The investigators aim to demonstrate sustained improvement in airway/pulmonary function and trajectory through 10 years of age.
The overall objective of this study is to determine the impact early nutritional and respiratory indices have on early CF lung disease. This knowledge will guide clinical management of infants with CF, who are now primarily diagnosed through newborn screening.
The purpose of this study is to further understand the effects of altitude on the physiology of gas exchange in the pulmonary microcirculation in normal subjects and in people with chronic obstructive pulmonary disease (COPD) measured as the single-breath diffusing capacity for carbon monoxide (DLCOsb). The study will determine a mathematical formula to allow for altitude corrections in both study populations to be used clinically in pulmonary labs.
In a randomized clinical trial (RCT) published in JAMA, the investigators have provided evidence that vitamin C supplementation (500 mg daily during pregnancy) ameliorates the effects of maternal smoking during pregnancy on offspring lung function and subsequent incidence of wheeze by 48% through 1 year of age. The investigators are currently completing a second RCT of vitamin C supplementation in pregnant smokers with more robust measures of pulmonary outcomes. The purpose of this ECHO application is to combine these 2 focused, interventional cohorts to allow critical longitudinal follow-up of respiratory outcomes in these children including the study of pulmonary function test (PFT) trajectories and incidence of recurrent wheeze/asthma from infancy through early adolescence in offspring of pregnant smokers randomized to vitamin C versus placebo.
The overall aims of this protocol are to determine whether prenatal supplementation with vitamin C to pregnant smokers can improve pulmonary function and decrease wheeze at 5 years of age in their offspring. This is a continuation of the VCSIP trial, to follow the offspring through 5 years of age. The hypothesis for this protocol is an extension of the VCSIP trial that supplemental vitamin C in pregnant smokers can significantly improve their children's PFTs and decrease the incidence of wheeze.
The purpose of this study is to assess if ACZ885 will improve lung function in association with reduction of tissue inflammation in patients with chronic sarcoidosis.
The purpose of this study is to obtain markers of airway inflammation from the exhaled breath condensate (the moisture in exhaled air) for comparison to blood based markers. These markers will be compared in tetraplegic, asthmatic and able-bodied control groups. Additionally, lung function testing will be performed, and the associations between breath condensate and blood markers and pulmonary function explored between groups.
Vitamin C supplementation (500 mg per day) given to pregnant women who can not quit smoking will improve the pulmonary function tests in their offspring measured at 3 months of age.
The purpose of this study is to develop and evaluate the usefulness of magnetic resonance imaging (MRI) using inert perfluorinated gases mixed with oxygen for regional assessment of pulmonary function. The proposed study seeks to determine regional qualitative and quantitative lung function information in the context of the clinical trajectory of chronic obstructive pulmonary disease (COPD) defined by the cross sectional cohort component. In the case of these perfluorinated (PFx)/oxygen mixtures, the availability of multi-liter quantities allows for wash-in/wash-out image acquisition and analysis allowing direct measures of gas trapping in a manner not easily achieved with any existing modality.
To explore the effects of corticosteroid therapy on pulmonary fibrosis and potentially pneumothorax in patients with mild PCP (pO2 \>70mmHg) combined with the standard of care treatment of antibiotic therapy.
Although single breath helium (He) dilution measurement (VASB) is currently used in pulmonary function laboratories to assess functional alveolar volume and diffusing capacity for carbon monoxide, the extent to which VASB reflects ventilatory and thoracic volume has not been prospectively determined in emphysema. We hypothesized that VASB underestimates rebreathe helium dilution volume (VARB), and plethysmographic volume (VApleth) as clinical and physiologic severity of emphysema increases.
Chronic lung diseases are disorders associated with abnormalities in any of the structures involved in the process of breathing and bringing oxygen into the lungs and blood. This includes abnormalities in the airways, lungs, blood vessels in and around the lungs, and the tissue covering the lungs (pleura). The purpose of this research study is to evaluate patients referred to the Cardiovascular and Pulmonary Branch of the National Heart, Lung, and Blood Institute (NHLBI) in order to; 1. Develop a better understanding of the causes and disease processes involved in disorders of the lungs 2. Identify patients eligible to participate in other P-CCMB research studies
The purpose of the study is to determine whether transfusion is associated with mild pulmonary changes.
This study will determine if airway resistance to airflow and pressure, measured by Oscillometry, is associated with abnormal findings on Cardiopulmonary Exercise Testing in subjects who are experiencing shortness of breath.
This study is a multiple within participant crossover study to evaluate the effect of ivacaftor on lung function in participants aged 12 years and older with cystic fibrosis (CF) who have phenotypic or molecular evidence of residual CF transmembrane conductance regulator (CFTR) function.
This study was developed in order for the professional-staff at the Pulmonary-Critical Care Medical Branch (PCCMB) of the National Heart, Lung, and Blood Institute to maintain their skills and increase their understanding of lung diseases. The study will permit PCCMB staff members to evaluate and treat patients with lung disease who do not meet the criteria for other research studies.
This phase II trial studies the effect of lutetium Lu 177 dotatate compared to the usual treatment (everolimus) in treating patients with somatostatin receptor positive bronchial neuroendocrine tumors that have spread to other places in the body (advanced). Lutetium Lu 177-dotate is a radioactive drug. It binds to a protein called somatostatin receptor, which is found on some neuroendocrine tumor cells. Lutetium Lu 177-dotatate builds up in these cells and gives off radiation that may kill them. It is a type of radioconjugate and a type of somatostatin analog. Lutetium Lu 177 dotatate may be more effective than everolimus in shrinking or stabilizing advanced bronchial neuroendocrine tumors.
This phase III trial studies cabozantinib to see how well it works compared with placebo in treating patients with neuroendocrine or carcinoid tumors that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Cabozantinib is a chemotherapy drug known as a tyrosine kinase inhibitor, and it targets specific tyrosine kinase receptors, that when blocked, may slow tumor growth.
