Filter by:Male and female subjects age 18-85 with lung disease will inhale 5ml/kg (patient body weight) hyperpolarized helium and will be scanned using MRI at 3 Tesla, to evaluate the Apparent Diffusion Coefficient (ADC), ventilation defect volume and percent ventilation.
the aim of this study to assess the relationship and compare physiological response between spot marching exercise test and 6 minute walk test in patient with chronic obstructive pulmonary disease
Exercise testing has become clinically important in the management and ongoing evaluation of patients with Cystic Fibrosis (CF) with higher rates of exercise tolerance and participation previously linked to lower mortality risk (1). Lower exercise capacity generally correlates with more severe lung disease (2,3) and landmark studies suggest that low exercise capacity as measured by peak oxygen capacity (VO2peak) and rate of decline in lung function (FEV1) are strong predictors of mortality (1,4). However not all studies have found pulmonary function tests (PFTs) to be reliable predictors of maximal exercise capacity (5), especially in relatively well preserved lung function (6,7). The wide distribution in physical capacity between fit individuals and end stage disease adds to complexity of assessment. Independent factors of age, genetics, habitual exercise, nutritional status and musculoskeletal conditions are all known to influence physical capacity in patients with CF (8,9). Maximal exercise testing places additional stress on cardiovascular, respiratory and peripheral systems providing more information around multiple influences on disease progression including degree of limitation in these major systems (10,11) and is useful for assessment of exercise desaturation, more common (but not always present) in advanced lung disease (5,12). With prediction of exercise performance and functional capacity from PFTs unreliable and the understanding that health status correlates better with exercise tolerance there has been an increase in maximal exercise testing for patient management (13). Many international centers now regard exercise testing as highly important with many assessing maximal exercise capacity annually to monitor disease progression, identify physical status and drive changes in medical, physiotherapy or nutritional management (14,15). The main vision is to develop a standardized incremental step test protocol suitable for adults with Cystic Fibrosis (CF), all ages, levels of fitness and disease state that is in line with current exercise testing recommendations (15). To develop a more useful field test to assess exercise tolerance and a more "user friendly" test than the currently available laboratory exercise test to allow for early detection of decline in physical function in the day-to-day clinical setting. To date no studies have been published in adults with CF where an incremental exercise step test has been investigated to assess exercise tolerance or determine maximum oxygen uptake (VO2max).
The purpose of the study is to assess the efficacy of high-frequency non-invasive ventilation on apnea duration, carbon dioxide clearance and oxygen delivery in healthy subjets and patients with lung disease.
This is a cross-sectional observational study, aiming to validate the accuracy of tidal breathing measurements in infants made by VoluSense Pediatrics, a lung function method based on electromagnetic inductance plethysmography, compared to an ultrasonic flowmeter. VoluSense Pediatrics consists of a flexible vest placed around the torso of the baby, and changes in tidal volume and flow is measured. The study will enable a better understanding of the usefulness of this equipment. The equipment is made by VoluSense Norway AS, and is owned by Haukeland University Hospital.
Magnesium (Mg) is involved in several pathways that could be affected in chronic obstructive pulmonary diseases (COPDs), namely in the contractility and excitability of neuro-muscolar endothelial cells and low-grade inflammation, a typical state of COPD. In this sense, several randomized controlled trials (RCTs) confirmed a positive role of Mg in asthma since long-period oral supplementation of Mg leads to a clinical and spirometric improvement. Subjects with COPD seem to have a reduced bioavailability of Mg probably due to the use of drugs that may increase Mg losses (e.g. beta-agonists and cortisones), to a reduced dietary Mg intake, and heavy smoking. A recent study showed that the administration of endovenous or aerosol Mg sulphate with beta-agonists acutely improve maximum expiratory flow during COPD relapses as well as the prolonged treatment with endovenous sulphate Mg led to a reduction in pulmonary hyperinflation and increase in muscles involved in respiration, with a consequent clinical and instrumental improvement. These evidences suggest that a chronic supplementation with Mg could improve COPD in clinical and instrumental parameters, but, at the best of our knowledge, no study was available in this sense.
The purpose of this study is to create an institutional registry of Chronic Obstructive Pulmonary disease through a prospective survey based on epidemiological data, risk factors, diagnosis, prognosis, treatment, monitoring and survival.
Chronic obstructive pulmonary disease (COPD) is the name for a collection of lung diseases including chronic bronchitis, emphysema and chronic obstructive airways disease. People with COPD have difficulties breathing, primarily due to the narrowing of their airways, this is called airflow obstruction. Some preclinical evaluations showed that COPD is closely related to chronic inflammation; therefore, this study aimed to use adipose-derived stem cells (ADSCs) in the form of non-expanded culture - that usually names as a stromal vascular fraction (SVF) in combination with activated platelet rich plasma (PRP) to treat this disease. Both SVF and PRP are autologous sources that obtained from adipose tissue and peripheral blood, respectively. This mixture is intravenously transfused into the patients.
Validation of Structured Light Plethysmography (SLP) in patients with conditions such as Chronic Obstructive Pulmonary Disease (COPD) that effect breathing and in healthy participants.
The purpose of this study is to evaluate the the diagnostic yield and safety of transbronchial lung biopsies (TBLB) with cryoprobe in patients with mechanical ventilation.
