The purpose of the study on the Prevention of Influenza and Other Wintertime Respiratory Viruses among Healthcare Professionals in Israel Effectiveness of Influenza Vaccine in Preventing Influenza Virus Infection, Missed Work, and Patient Exposure: A Prospective Cohort Study of Healthcare Personnel (to be called the Healthcare Personnel or HCP study throughout this Data Security Plan) is to investigate vaccine effectiveness and respiratory illness among healthcare personnel (HCP). This will help to better understand the factors that influence influenza vaccination choice, individual vaccine response, and whether or not the influenza vaccine helps to prevent influenza in HCP.
Chronic respiratory diseases including chronic obstructive pulmonary disease (COPD), bronchiectasis (BE) or pulmonary fibrosis (PF) are usually not curable with damaged pulmonary structure and function. Bronchial basal cells are proved to regenerate bronchus and alveoli to repair the pulmonary injuries. In this study, we intend to perform an open, single-armed phase I clinical trial by transplantation of autologous bronchial basal cells on patients suffered from COPD, BE or PF. During the treatment, autologous bronchial basal cells, which were isolated from fiberoptic bronchoscopy and expanded in vitro, will be injected directly into lesions by fiberoptic bronchoscopy after careful characterization. In the following 6 months, the safety and efficacy of the treatment will be monitored by measuring the key clinical indicators.
This is the registry of control participants for patients with various respiratory diseases. We screened healthy volunteers who visited Seoul National Hospital Healthcare System Gangnam Center for routine health check-up, and enrolled patients who agree to participate in the study. The participants undergo baseline questionnaires, provide blood specimen and information of the results of health check-up. We will include participants as controls if they have no significant respiratory symptom and no significant radiographic abnormality. The data from this registry will be compared with those from other registry of various respiratory diseases
Chronic inflammatory pulmonary diseases including chronic obstructive pulmonary disease (COPD), interstitial lung diseases (ILD), bronchiectasis, and cystic fibrosis (CF) are characterized by lung inflammation and remodelling. Clinical, functional, microbiological, biological, pathological and prognosis features are highly variable and heterogeneous. A precise phenotyping is a key-element to better understanding the pathophysiology of these chronic inflammatory diseases and to develop innovative treatment strategies. The objectives of this prospective study is to analyze the clinical, demographic, biological, morphological, pathological, and microbiological characteristics in a cohort of patients diagnosed with COPD, ILD, bronchiectasis, and CF. The associations between clinical, demographic, biological, morphological, pathological, and microbiological features will be assessed. The Cohort for Research and Innovation in Chronic Inflammatory Respiratory Diseases (the RINNOPARI Project: Recherche et Innovation en Pathologie Respiratoire Inflammatoire) is a monocentric study conducted at the University Hospital of Reims, France. Adult patients (>18 year-old) followed at the University Hospital of Reims and diagnosed with COPD, ILD, bronchiectasis, or CF will be considered for inclusion. Patients will sign an informed consent for inclusion. Exclusion criteria include "subjects protected by the law" as required by the French authorities. Control patients with no respiratory diseases after clinical and pulmonary function tests assessment will be also included. The expected number of patients included is 225 (COPD, n=100; CF, n=25; bronchiectasis, n=25; ILD, n=25; controls, n=50). Inclusion will be conducted for 36 months from September 2016 (9/30/2016) to September 2019 (9/30/2019). For all COPD, ILD, bronchiectasis, and CF patients included, data will be registered at inclusion, and at follow-up visits for 10 years. Patients will be followed-up as usual care with no specific therapeutic intervention. For control patients, data will be registered at inclusion with no follow-up. Data will be registered in a centralized anonymized database. The characteristics of the patients will be described as mean and standard deviation for quantitative data and as number and percentages for qualitative data. Comparisons and associations between groups and variables will be analyzed by Student, Wilcoxon, Chi2, Fischer exact, and Spearman tests as applicable. A p<0.05 will be considered as significant. This study should help to better characterize clinical, demographic, biological, morphological, pathological, and microbiological characteristics and phenotypes in chronic inflammatory respiratory diseases.
The study consist of a retrospective analysis of the etiologies, investigations and outcomes of patients presenting between 2005 to 2010 with hemoptysis in a North-American Tertiary center.
Nasal, tracheal and bronchial sampling of MLF in patients with idiopathic pulmonary fibrosis(IPF), sarcoidosis, tuberculosis(TB), asthma and COPD. Similar sampling from healthy controls for comparative data. Aim: To characterise the molecular basis of the upper and lower airway mucosa inflammatory response in different respiratory diseases. To assess molecular biomarkers and signatures to see if these can aid diagnosis, stratification of these respiratory diseases. To direct personalised medicine and rationalise therapy. Outcome measures:Measurement of levels of inflammation, coagulation, complement activation and fibrosis in MLF, transcriptomics from nasal curettage and airway brushings and to assess the tolerability of absorption procedures in these patients.
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).
This observation will look at patient care decisions of the primary healthcare provider utilizing the results of the DNA testing of patients' metabolic pathways using 2C19, 2C9, 2D6, 3A4, Factor II, Factor V and MTHFR and VKORC1. Findings of the data collection will be published to optimize the benefits of pharmacogenomics testing and publish health outcomes.
The goal of this study is to evaluate the usefulness of hyperpolarized (HP) 129Xe (xenon) gas MRI for regional assessment of lung function in a normal population of adults for the purposes of obtaining optimal images through MRI.
