Active clinical trials for "Respiratory Tract (Lung and Bronchial) Diseases"

To investigate if asthma affects the inflammatory balance of the endometrium and thereby interfere with implantation, as indicated by the characteristics of the inflammatory cells in the endometrium and airways in women with asthma who are referred for IUI or IVF due to infertility, compared to otherwise healthy women who are referred for IUI or IVF due to infertility.

The COVID-19 pandemic is having a profound impact on the world. As of May 18, 2020, there were 4,889,287 confirmed cases and 322,683 deaths globally. The healthcare system is wrestling with a virus that threatens to overwhelm hospital capacity, while simultaneously confronting an unprecedented reduction in elective and non-essential care. A survey by the American Cancer Society showed that 50% of cancer patients and survivors reported some impact to their healthcare due to the COVID-19 epidemic. A recent survey was conducted by Forbes et al to evaluate the changes in GI and endoscopy practices in North America. However, the impact of this epidemic on Pulmonology units ( bronchoscopy, thoracoscopy, ultrsonography and sleep lab) globally has not been studied.

The current study is aimed to determine the procedures applied in the dysphagia clinics during the COVID-19 pandemic period. A questionnaire consisting of 30 questions will be implemented. Each participant will be asked to answer the questions.

Intratracheal surfactant treatment is applied in Respiratory Distress Syndrome (RDS) Continious Positive Airway Pressure(CPAP) treatment. In recent clinical studies, two similar methods have been studied with a thin catheter without endotracheal intubation in the application of surfactant. In our neonatal intensive care unit, respiratory support is given with nasal CPAP and Humidified Heated High Flow Nasal Cannula (HHHFNC) instead of classical invasive (intubated) mechanical ventilation methods. In CPAP method, heated and humidified air is given a certain pressure (6-8 cmH2O), while in HHHFNC method, heated humidified air is given at a certain flow rate (6-8 L / min). This study was planned to compare the results of infants who were given surfactant with MIST (Minimal Invazive Surfactant Treatment) method under CPAP or HHHFNC support in the treatment of respiratory distress syndrome in premature babies. During surfactant application, babies will be monitored (as in all babies in the NICU) saturation, peak heart rate, perfusion index (the ratio of nonpulsatile flow in the capillary bed) and t values will be recorded. For all these reasons, monitoring of PI (Perfusion Index), PVI (plethysmographic variability index) and continuous transcutaneous PCO2 and PO2 values are of great importance for the prevention of mortality and morbidity, as well as monitoring of oxygen saturation values with pulse oximetry in premature babies. In our hospital, it was planned to take a total of 40 patients born under 32 weeks and less than 1500 grams (20 patients being in the HHHNFC, 20 patients in the CPAP group). Patients will be consecutively distributed to two groups until they reach the specified number of patients. In this study, it was aimed to monitor continuous oxygen saturation, PI, PVI, transcutaneous PO2 and PCO2 measurements just before, during and after the surfactant application and to compare the results of babies who received nCPAP and HHHFNC support. At the end of the study, all data will be entered in an SPSS (Statistical Package for the Social Sciences) file and study statistics will be made. A database will be created using SPSS software. A p value of <0.05 was determined as the limit of significance.

This experiment is designed to analyze the metabolites in body fluids from patients with active tuberculosis and latent tuberculosis infection also with health volunteer, then combine the metabolic product features with clinical characteristics, to develop a kind of metabolites targets to evaluate the progress in tuberculosis, thus provide a basis for further utilization of humoral metabolites in the diagnosis of tuberculosis.

This research study will evaluate the association of Androgen Receptor (AR) gene expression and COVID-19 disease severity and mortality. The research procedure involves collection of a single saliva sample which will be mailed to the participants by the study team. This saliva will be used in a COVID-19 Androgen Sensitivity Test (CoVAST) which will detect AR gene expression. Eligible participants are males, at least 18 years or older, and have tested positive for COVID-19.

Asthma is a chronic inflammatory disease of the airways that causes recurrent episodes of wheezing, breathing difficulties and coughing. The prevalence of asthma is 8% in school-aged children and 30% in preschoolers, making asthma the first chronic disease in children. Symptoms are due to diffuse but variable airway obstruction, reversible spontaneously or after inhalation of beta2 agonists (β-2a) such as salbutamol. Exacerbations of asthma are frequent and difficult to assess by parents and the patient himself. It is estimated that approximately 2.5% of children with asthma are hospitalized annually. The global burden caused by asthma can thus be reduced by improving early detection of bronchial obstruction, prescribing immediate treatment with the appropriate background therapy, and reliably and objectively assess response to treatment. The natural history of asthma symptoms in children shows a great intra and inter-individual variability. The difficulty of assessing the severity of an attack by the parents or the child himself, when he is old enough to control his chronic disease, is a key element in the management of asthma and allows the treatment to be adapted quickly, sometimes avoiding hospitalization. Healthcare professionals can assess the severity of the episode using the Pediatric Respiratory Assesment Measure (PRAM) score, which has the advantage of being adaptable at any age. The Global Alliance against Chronic Respiratory Diseases (GARD) integrates in its diagnostic strategy for chronic respiratory diseases, the lung function test, which allows the quantification of respiratory function in the context of diagnosis and long-term follow-up. Although spirometry are non-invasive tests, they still require a high level of patient cooperation, which remains problematic before the age of 7 years. The digital stethsocope integrates a capacity for recording auscultations and data transmission to high-performance software. This has made it possible to extend auscultation beyond what was audible to the human ear alone (over 20-20,000 Hertz).Auscultatory sounds analysis, particularly those most often associated with obstructive syndrome could be simple, reproducible and a reliable method of assessing the severity and response to treatment in children's asthma. Major advances in signal processing and unsupervised learning in artificial intelligence research provide the potential for high-performance analysis of physiological measures.

Coronavirus has caused containment of more than half of the world's population and a major and rapid reorganization of clinical and support services. The spread of coronavirus (COVID-19) has posed significant challenges for dental surgeons and associates who are at high risk of COVID-19 infection due to close face-to-face contact. However, there is currently no data on the influence of this epidemic on the practice and feelings of dental surgeons and associates

In this retrospective study, we aim to investigate the demographic and clinical features of patients with nontuberculous mycobacteria (NTM) lung disease in our hospital and the trends and diversity of NTM species isolated in the period of 2009-2018.

Alsace was particularly and early on affected by SARS-CoV-2 and quickly implemented a reduction in scheduled admissions and non-urgent surgical interventions, making it possible to reduce requests for labile blood products linked to non-urgent surgical procedures. as has been reported in the literature; the population containment measures also led to a major reduction in traffic - and consequently accidents on the public roads. At the same time, other demands for blood products related to activities such as onco-hematology were little affected. Finally, the blood banks have adapted their collection procedure. To answer these questions, we propose to conduct a retrospective study over two parallel periods of 2019 and 2020 of the consumption of blood products on the one hand and the availability of stocks on the other hand.
