Filter by:This study will determine if resistance of the airway to airflow and pressure, measured by Impulse Oscillometry, is impacted by a deep breathe maneuver in a small cohort of healthy human subjects.
The COVID-19 pandemic has presented considerable challenges to global health services and dictates almost every aspect of medical practice and policy. The menopausal transition may have significant consequences for respiratory health as COVID 19 symptoms subsides, lung function testing should be done to assess the consequences of this virus on lung health especially in menopausal woman.
Physical inactivity and sedentary time are highly prevalent worldwide and are associated with many adverse health outcomes. Workers adults spend two-thirds of their workday sitting, so they are particularly at risk. Exercise is considered a preventive and treatment tool for diseases, however, the effects of Concurrent Training (that is, aerobic plus resistance training) are not well established in healthy adults. This research project aims to analyze the effects of a concurrent training program on metabolic profile, lung function, stress and quality of life, as well as body composition and physical fitness in sedentary adults. This is a single-blinded two-arm RCT with parallel groups. After completion of baseline assessments, eligible participants will be randomized in a 1:1 ratio to participate in concurrent training group or control group. Repeat assessments will be taken immediately post 8 weeks and post 16 weeks of intervention.
This is a prospective observational study aiming: 1) To quantify lung function using perfusion dual energy computed tomography (DECT) and use this information at the time of treatment planning with preferential sparing of functional lung parenchymal 2) to validate results of lung function obtained using DECT with lung perfusion scintigraphy results, the current standard method; 4) to compare dosimetry of whole lungs vs. functional lungs in patients treated with either stereotactic body radiotherapy (SBRT) for early stage lung cancer or conventional radiotherapy for locally advanced lung cancer and 5) to evaluate lung function 6, 12 and 24 months post-radiotherapy with both perfusion DECT and pulmonary function tests and compare radiation dose-map to functional lung-map.
The physiological derangements in subjects suffering from long-term symptoms following a Covid-19 infection (Post-COVID-19 Syndrome) are poorly understood and evaluated. This study will recruit subjects with a clinical diagnosis of Post-Covid-19-syndrome) who are scheduled for either of lung function testing, cardiopulmonary exercise testing or cardiac ultrasound. Patients' symptoms will be correlated to physiological measures and compared to predicted values. In addition, in 20 patients, symptoms and physiological measures will be correlated to epigenetical alterations, or DNA-methylation patterns. In addition, a subset of patients will be examined a year after the baseline testing in order to follow the progress of the disease.
Study aims to determine if functional lung avoidance based on perfusion single photon emission (SPECT)/CT scan, improves toxicity outcomes for patients with advanced lung cancer undergoing chemo-radiotherapy. Functional avoidance implies a dose plan that takes functional distribution in the lung into account, and avoids highly functional lung volumes sparing them from radiation.
A multicenter prospective cohort study performed at 6 major teaching hospitals in Southern Norway to study patient reported outcomes, lung function and pulmonary CT in patients at 3 and 12 months after hospitalization for coronavirus disease 2019 (COVID-19).
People spend up to 90% of their life indoor, and the way we live and behave in our homes has substantial effects on our health and well-being. Particle contamination is suggested to have substantial negative effects on health, with candles and cooking emitting the largest amount of particles, thus being the largest contributors to indoor air pollution. The overall aim of the present project is to contribute to increased understanding of the association between indoor particulate air pollution and health and well-being.
Recently, the investigators described a new mucoid phenotype of Staphylococcus aureus cultured from the airways of cystic fibrosis (CF) patients.In this observational study, the investigators plan to determine the prevalence of mucoid S. aureus in respiratory specimens of CF patients and a possible impact of mucoid S. aureus on lung disease severity.
Long-term variability analysis of peak expiratory flow (PEF) and forced expiratory volume in 1 s (FEV1) has been successfully used in research to predict the exacerbation of the disease in adult individuals with asthma. However, there is a paucity of data regarding PEF and FEV1 variability in asthmatic children and adolescents. Such a task requires at least daily PEF and FEV1 measurements, recording in diaries, and periodic evaluation of the data. The process may be proven both complicated and time consuming, thus reducing patients' adherence. Recent advances in biosensor technology have permitted the development of reliable, low-cost, portable spirometers, able to connect with smartphones and monitor lung function parameters in real time and from a distance. The objectives of the present study is the assessment of PEF and FEV1 variability: a) in healthy children and adolescents, in order to define the normal daily fluctuation of PEF and FEV1 and the parameters that may influence it, and b) in children and adolescents with asthma, in order to explore the differences from healthy subjects and reveal any specific variability changes prior to exacerbation. Such data would improve our understanding regarding the disease and permit the development of integrated tools for assessing the level of asthma control and the risk of future exacerbations. The study will include 100 healthy children and adolescents aged 6 to 18 years for the assessment of normal PEF and FEV1 variability, and 100 children and adolescents of the same age with diagnosed asthma for the assessment of PEF and FEV1 variability in asthmatics. PEF and FEV1 measurements will be performed using an FDA-approved portable spirometer (MIR Spirobank Smart) capable to connect to smartphone. Each participant will receive his personal spirometer. Measurements will be performed twice a day between 07:00-09:00 and 19:00-21:00 hours and dispatched via email to a central database for a period of 3 months. PEF and FEV1 variability will be assessed by detrended fluctuation analysis, aiming to define the normal pattern (healthy controls) and to detect and quantify the deviations (asthmatics). The anticipated duration of the study is 24 months.
