Filter by:The study design is cross-sectional using a self-completion questionnaire in an English speaking multi-ethic population within Leicester and Leicestershire. The study will adopt a convenient and purposive sampling recruitment strategy across a variety of settings within Leicestershire to facilitate recruitment of a wide range of participants.
The Electrical Impedance Tomography (EIT) is a non-invasive exam. This exam performed on the lung continuously produces cross-sectional images of lung function. It may be relevant in lung description.
Assessment of lung function requires the evaluation of pulmonary function by spirometry. However, some patients (e.g. children, elderly, or diseased individuals) may have difficulty performing the related forced maximal respiratory maneuver correctly. Forced oscillation technique (FOT) is increasingly being used in clinical settings to evaluate lung function noninvasively by measuring the mechanical input impedance of the respiratory system. FOT measures lung impedance during tidal breathing, requiring minimal patient cooperation. Recently a new methodology (within breath analysis) has emerged to evaluate changes that occur in the impedance during the breathing activity. The within-breath calculation of impedance allows separating the contribution of inspiration and expiration to the measured parameters. The purpose of this study is to establish reference ranges for within breath FOT parameters and their short term variability.
The study will assess the effectiveness of AIT treatment in real clinical practice in Germany.
A randomized, open-label, single-dose, 3-period, 6-sequence, 3-way crossover study
High flow nasal cannula (HFNC) therapy is non-invasive respiratory support designed to deliver a high flow of heated humidified air, with or without entrained oxygen, via specifically designed nasal prongs. Initially developed for preterm infants, the application of the technology is rapidly spreading to include pediatric patients with various indications, including bronchiolitis, obstructive sleep apnea (OSA), tracheomalacia, asthma, post- extubation support, and even adult hypoxemic respiratory failure. Since it appears to be better tolerated than traditional modes of non-invasive ventilation, such as continuous positive airway pressure (CPAP) or bilevel positive airway pressure (BiPAP), it is increasingly used outside the intensive care setting, despite limited evidence of its safety and efficacy. In Israel, HFNC is approved for home support of children requiring non-invasive respiratory support on the recommendation of a paediatric pulmonologist or intensivist, provided that CPAP and BiPAP have been trialed and deemed not tolerated by the patient. At Schneider Childrens' Medical Center of Israel (SCMI), a tertiary paediatric hospital, therapy is commenced during a brief inpatient stay, at a period of clinical stability. Parents are trained in the use of the device and flow rate is titrated to clinical response. The investigators aim to describe the safety, indications, parameters of utilization, length of treatment, clinical outcomes and parental satisfaction of HFNC in the paediatric home setting.
The diagnosis of a lung function anomaly requires the evaluation of pulmonary function by spirometry. However, some patients (e.g. children, elderly, or diseased individuals) may have difficulty performing the related forced maximal respiratory maneuver correctly. Forced Oscillation Technique (FOT) measures lung impedance during tidal breathing, requiring minimal patient cooperation. The purpose of this study is to establish the diagnostic accuracy of FOT parameters alone or in combination with lung volumes in detecting lung function anomalies as compared with spirometry and with the diagnosis made by the physician.
Randomized controled trial to compare oxygen desaturation during fiberoptic bronchoscopy using oxygen administered with nasal prongs and high flow nasal cannula. Drops in oxygen saturation are frequent during bronchoscopy and limit the procedure compromising patient security. The investigator's aim is to contribute to select better way of oxygen administration which could prevent desaturations during bronchoscopy in children.
Open and multicenter randomized clinical trial (1:1) comparing limited screening with extended screening with the performance of Positron emission tomography-computed tomography (PET-CT) scan in the search for neoplasms in patients with unprovoked venous thromboembolic disease at high risk of developing cancer at follow-up. Introduction: Cancer screening in patients with unprovoked venous thromboembolic disease (VTE) is controversial. In the last years, a score has been developed that selects patients at high risk of developing cancer during follow-up. Objective: To estimate the impact of an active cancer search strategy using 18-fluordesoxiglucose (FDG) PET-CT in unprovoked VTE with high-risk to develop cancer. Specific Objectives: 1) Number of neoplasms diagnosed in the screening process: 2) number of neoplasms diagnosed at an early stage, 3) impact on survival of the strategy; and 4) impact on the quality of life. Cancer will be considered from 30 days up to 12 months after the diagnosis of VTE. Scope: 20 Spanish hospitals. Design: Open-label, multicentre Randomized clinical trial (1: 1) comparing the performance of PET-CT versus limited screening for cancer. Population: Patients older than 18 years with unprovoked VTE at high risk of presenting cancer at follow-up (≥3 points in the score of Jara-Palomares et al., Chest 2017). Follow-up: 12 months after VTE. Sample: The sample size calculated is 650 patients, to obtain a power of 80%, with a level of significance of 5%, and taking into account a 10% loss of follow-up.
The Hamburg City Health Study (HCHS) is a large, prospective, long-term, population-based cohort study and a unique research platform and network to obtain substantial knowledge about several risk and prognostic factors in major chronic diseases.
