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

Severe acute respiratory syndrome coronavirus 2 (COVID-19) poses substantial challenges for health care systems. With a vastly expanding amount of publications on COVID-19, clinicians need evidence synthesis to produce guidance for handling patients with COVID-19.

COVID-19 antibodies testing among healthcare workers to evaluate the role of Covid 19Ab testing as screening method for detection of covid 19 infections among laboratory health care workers ,assess the relationship between the infection with Covid 19 and different laboratory categories/area and assessemt of efficiency personal protective equipment (PPE) in different laboratory categories/area.

A novel coronavirus was identified in late 2019 in Wuhan, China On 11 February, The International Committee on Taxonomy of Viruses (ICTV) announced that the official classification of the new coronavirus (2019-nCoV) is called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The World Health Organization (WHO) announced on the same day that the official name of the disease caused by the virus is Corona Virus Disease-19 (COVID-19). WHO has declared the infection a Pandemic on March 11, 2020. Based on previous studies on SARS in 2003 and SARS-MERS 2013 there was a genetic polymorphism associated with the susceptibility and severity of the disease. Interleukin-12 (IL-12) is a cytokine secreted by activated phagocytes and dendritic cells. It plays a pivotal role in promoting Th1-type immune responses and cell-mediated immunity. IL-12 triggers many biological functions: it stimulates the proliferation of activated T- and NK-cells, enhances T- and NK-cell-mediated cytolytic activity, and induces the production of IFN-γ by both T-and NK-cells. The interferon-γ production induced by IL-12 forms a major link between innate and adaptive immunity. A recent study revealed that interferon-mediated immunopathological events are associated with atypical innate and adaptive immune responses in SARS patients. Also, TNF-α is a key mediator of the inflammatory response and is critical for host defense against a wide variety of pathogenic microbes. However, the over-expression of this cytokine may lead to badness in disease recovery. The dual role of TNF, acting as an agent of both innate immunity and inflammatory pathology, poses a considerable challenge for gene regulation.

The aim of the work is to Assess the incidence of weaning induced pulmonary adema(WIPO). Assess the risk factors of WIPO. Evaluate the role of lung ultrasound in detecting WIPO during spontenous breathing trial(SBT). Detect the threshold of B-line increase (Delta-B-lines) that provided the best diagnostic accuracy of WIPO.

Healthcare centers treated several hundreds of patients with Covid-19 and prospectively gathered information in electronic format between March, 2020 to April, 2020. In the course of Covid-19 treatment, physicians employed several drugs, including hydroxychloroquine, azithromycin, lopinavir/ritonavir, tocilizumab, baricitinib, sarilumab, corticosteroids and systematic antibiotics (list is not exhaustive). This cohort study aims to assess factors associated with clinical outcomes in patients hospitalized for Covid-19, by analyzing associations between treatments and outcomes. All data are collected in electronical records during routine practice.

Nosocomial infections are increasing rapidly both internationally and domestically, especially carbapenem-resistant Klebsiella pneumoniae infections. However, there were still lack of evidence about the risk and prognosis in Taiwan. The choice of drug and related sensitivity test was also limited. We would analyze the infection risk, prognosis, and drug sensitivity of Klebsiella pneumoniae and focus on strategy to manage carbapenem-resistant Klebsiella pneumoniae infections.

The main outcomes of this study are to establish a cohort of well-phenotyped asthma patients with a recent history of an exacerbation. We aim to describe exacerbation profiles (phenotypes) of the cohort in terms of inflammatory/biomarker profile and bacterial/viral infection status and to compare these with exacerbation events in the sister APEX cohort.

The purpose of the study is to quantify the use of pain medications given to children aged 3 - 12 years as well as their pain level through pain scores after they have undergone a tonsillectomy or adenotonsillectomy surgery at Doernbecher Children's Hospital (DCH). We would like to learn more about the pain medications given and the pain scores of children post-surgery for the first 5 days following discharge from the hospital.

This study will be conducted as a registry to identify asymptomatic or symptomatic persons to determine whether they carry SARS-CoV-2 antibodies.

A large number of Health Care Workers (HCWs) would be potentially getting exposed to COVID19. Some of them would be asymptomatic or may get subclinical symptoms. Our HCW would have higher exposure and possibly higher seroconversion either symptomatic or with clinical symptoms than the general population. This study is aimed to understand the rate of seroconversion states at different stages of exposure. It is crucial to collect baseline immune status and the early immunological changes that might occur in asymptomatic or symptomatic health care workers and to compare that with the suspected or confirmed cases by following them for six weeks.
