Filter by:The aim of this clinical trial is to compare the positive predictive value of the combination rapid nasal provocation test (RNTP) + skin tests (TC) + specific immunoglobulins E (IgEs) to the combination of TC + IgEs (strategy currently used in clinical practice) concerning the efficacy of treatment with Allergen immunotherapy (ITA) at 1 year, in patients with symptoms suggesting allergic rhinitis to house dust mites.
The objective of the present study is to describe the negative impact on oral and gut microbiota of a severe acute respiratory syndrome SARS-CoV-2 infection in patients hospitalized in intensive care units (ICU). The study would like to compare their microbiota to the microbiota of ICU patients, non-infected by the SARS-CoV-2.
The study project will aim at the evaluation of the occurrence of exercise desaturation phenomenon during two different modalities of exercise (walking and stepping condition). This study will allow determining the sensibility of the 3-minute step test to detect exercise desaturation, in comparison with the gold standard (6-minute walking test). The 3-minute step test could therefore appear as a complementary tool for the evaluation of oxygen desaturation in chronic respiratory disease.
COVID-19 is respiratory disease caused by the severe acute respiratory coronavirus 2 (SARS-CoV-2), a novel coronavirus which has spread rapidly across the world with over 149.9 million laboratory confirmed cases and over 3.1 million reported deaths since December 2019. Approximately 4-8% of hospitalized patients with COVID-19 have co-infection with bacterial pathogens however there is widespread and often broad-spectrum antibiotic use in these patients. This is a prospective, multi-center, non-inferiority pragmatic clinical trial of antimicrobial stewardship prospective audit and feedback versus no antimicrobial stewardship intervention on physicians attending to patients with proven SARS-CoV-2 infection confirmed by nucleic acid testing in the preceding 2 weeks of hospitalization for acute COVID-19 pneumonia. Prospective audit and feedback is the real time review of antibacterial prescriptions and immediate feedback to prescribers to optimize antimicrobial prescriptions. Hospital beds will be stratified by COVID unit and critical care unit beds, and will be computer randomized in a 1:1 fashion into 2 arms (antimicrobial stewardship intervention versus no antimicrobial stewardship intervention) prior to study commencement at the participating site. Patients hospitalized to study-eligible beds will be followed for primary and secondary outcomes. The objective of this study is to determine the effect of an antimicrobial stewardship intervention (prospective audit and feedback) on clinical outcomes in patients hospitalized with acute COVID-19.
The objective of this study is to assess the inoculation-related symptoms and long-term effects of COVID-19 vaccines in patients with lung cancer or pulmonary nodules in a real-world setting. The investigators aim to provide high-quality evidence for the COVID-19 vaccines in cancer/pre-cancer patients, and to address their concern about the safety profile of the newly developed vaccines.
The Investigators plan a single center study to get preliminary data to answer a number of fundamental questions directly related to management of COPD. The research will determine whether ventilation heterogeneity and distribution of ventilation inform, determine, assist or drive the: 1) status or clinical course in patients with COPD, 2) understanding of factors associated with activities of daily living and quality of life in patients , 3) risk of exacerbation or hospitalization in those with COPD, and 4) predictors of therapeutic pathway or treatment regime.
This study aims to validate dried blood spots (DBS) for SARS-CoV-2 (Severe Acute Respiratory Syndrome 2) antibody detection in elderly individuals.
Lung magnetic resonance imaging (MRI) with proton and inhaled inert gases has demonstrated a clinical ability to provide valuable structural and functional information in lung disease. Advances in lung MRI methods have led to the STH department handling clinical imaging referrals from local and national respiratory units. Hyperpolarised Xenon-129 gas MRI is now the gold-standard MRI modality used in clinical practice for asthma and COPD in Sheffield. In this new study, the investigators will use Xenon gas MR imaging and 19F gas MR imaging to obtain physiological, structural, and functional information about patients with known respiratory disease, namely asthma and COPD. Up to 20 patients with asthma and up to 20 patients with COPD will be recruited. Study visits will involve lung function tests and imaging using proton MRI, hyperpolarised xenon gas MRI, and 19F perfluoropropane MRI. After initial baseline assessments, patients will be followed up after 3 and 6 years to investigate the utility of MRI and lung function measurements in tracking disease progression over time. In addition, during the COVID-19 pandemic will also be studying the long term effects of this novel disease. The investigators will use Xenon gas MR imaging and pulmonary vascular 1H MR imaging to obtain physiological, structural, and functional information about patients with COVID-19, including hospitalised patients and mild, non-hospitalised COVID-19 patients. Participants may be invited for baseline assessments during the symptomatic phase of the disease and/or be followed up after 6, 12, 24 and 52 weeks (in line with clinical follow up for hospitalised patients) to investigate long term effects of this novel disease. This novel approach will provide mechanistic insight in to clinical observations such as : (i) why previously healthy patients can respond so poorly to oxygen/ventilation therapy, (ii) why patients respond to proning, and (iii) whether this is caused by alveolar-capillary interstitial changes and /or microvascular clotting in the pulmonary vasculature (leading to V/Q mismatch), and (iv) whether these acute changes lead to long term interstitial lung disease.
The main objective of the proposed study is to evaluate the impact of coronavirus (2019-nCoV), hereafter COVID -19, on patients' loss of functional capacity after completion of hospital treatment. Specifically, the research will focus on examining changes in musculoskeletal, cardiovascular, and respiratory function, as well as motor control. In addition, we aim to evaluate rehabilitation treatments after recovery from COVID -19 and consider additional preventive measures based on previous experience.
Lung diseases are one of the most common causes of emergency room visits. There are very few tools that are able to predict which patients will have a worsening or increasing severity of their condition. There are also limited ways to check the health of patients with respiratory conditions at home and during the time between medical appointments. The ADAMM-RSMTM device records heart rate, breathing rate, temperature, cough and activity while wearing it. This study will test participants willingness to wear the device and perform ongoing monitoring to assess the possibility to predict the onset and increases in severity of their lung conditions.
