Active clinical trials for "COVID-19"

The aim of the research is to study the immune checkpoint linked to the HLA-G molecule in the dysregulation of the control of COVID-19 infection.

Medical personnel working in the Intensive Care Unit will be examined by means of tests. Their aim is to check how work-related stress in a potentially lethal threat affects the occurrence of depression, stress, anxiety and sleep disorders. We also want to check whether people working in such extremely difficult conditions show no greater interest in death.

During the Covid-19 pandemic, non-operative management for acute appendicitis (AA) was implemented in the UK. The aim of this study was to determine the efficacy and outcomes of conservative versus surgical management of AA during the pandemic.

The viral pandemic of the coronavirus disease 2019 (COVID-19), generated by a novel mutated severe acute respiratory syndrome coronavirus (SARS-CoV-2), has become a serious worldwide public health emergency, evolving exponentially. While the main organ targeted in this disease is the lungs, other vital organs, such as the heart and kidney, may be implicated. The main host receptor of the SARS-CoV-2 is angiotensin converting enzyme 2 (ACE2), a major component of the renin-angiotensin-aldosterone system (RAAS). The ACE2 is also involved in testicular male regulation of steroidogenesis and spermatogenesis. As the SARS-CoV-2 may have the potential to infect the testis via ACE2 and adversely affect male reproductive system.

Effectiveness of the use of Tenofovir/Emtricitabine in addition to personal protective equipment for the prevention of the transmission of SARS-COV-2 to health care personnel. A Randomized Clinical Trial. This is an experimental study whose aim is to evaluate the effectiveness of a drug to prevent infection with the virus that causes COVID-19 (SARS-CoV-2), in health care workers. The drug under study is Tenofovir /Emtricitabine, a well-known antiretroviral, which is safe and is used as prophylaxis and treatment for HIV and other viral infections such as Hepatitis. Several laboratory-based studies indicate that this drug has the potential to inhibit SARS-CoV-2 replication. In addition, one study in HIV infected persons found that those taking Tenofovir /Emtricitabine tended to have a lower occurrence of COVID-19. In this study, we will compare the occurrence of infection with SARS-CoV-2/ COVID19 in health care workers between those assigned to an intervention group and those assigned to a control group. The intervention group will receive Tenofovir /Emtricitabine during 60 days in addition to the use of personal protective equipment (PPE), and the control group will receive a placebo during 60 days in addition to the use of personal protective equipment (PPE). The study will recruit 950 health professionals above 18 and less than 70 years, working in the emergency room, COVID wards and intensive care units of seven hospitals in Colombia. To make the comparison groups very similar, the participants will be assigned through a random mechanism to either the intervention (475), or the control (475) groups. In order to prevent biases in the evaluation of the results, neither the participants nor the clinical investigators, data managers, analysts and support personnel will know which intervention the participants are receiving. To determine the occurrence of infection with the virus the study will use both molecular tests that detect the presence of viral genes in respiratory secretions, and serological tests that detect the response of the immune system to the virus. The study will evaluate also the safety of this drug determining the occurrence of adverse events.

As of May 26, 2020, 5,508,904 confirmed cases (145,279 in France) of COVID-19 and 346,508 deaths (28,457 in France) have been reported since December 8, 2019 worldwide. The rapid increase in the number of cases in our territory caused France to pass to level 3 of the epidemic on March 14, 2020. The natural history of this disease is still poorly understood, particularly in patients infected with HIV, patients considered to be at higher risk for severe forms. Knowing the seroprevalence in the population of people living with HIV will make it possible to better understand the Covid infection in immunocompromised patients, know the percentage of immunization and the persistence or not of the antibodies over time, specify the protective nature or not of these antibodies detected.

The goal, with this study, is to leverage Northwell Health System's diverse workforce and robust testing structures, to contribute data-driven, evidence-based strategies to better understand the sustained prevalence of antibodies and how conferred immunity may be modified by environmental factors. The objective is to investigate the COVID-19/SARS-CoV-2 disease prevalence and trajectory over time, by conducting follow-up antibody testing on employees who consented to participate in research during the initial workforce offering. From 70,812 employees contacted, 46,117 were tested and received initial results. Of those participants, approximately, 32,000 agreed to be re-contacted, and 34,000 consented to research. The investigators plan to conduct an additional five rounds of testing that would sample individuals over a two-year period. This study is significant because it leverages Northwell Health's advanced laboratory systems to conduct serosurveillance of antibodies to COVID-19/SARS-CoV-2 across a large and diverse workforce, while taking into account the contextual environmental and occupational exposures that may modify continued immunity to the virus. Northwell Health's employee health services (EHS) is poised to act quickly to adapt policies and practices, where needed, to protect the workforce. The study is also innovative because it will be linking work environment and community measures with COVID-19 seropositive prevalence patterns over time, to build a better understanding of the disease and its controls at the population level. The expected outcomes include serial serology results as a measure of full or partial short-term (6 months) and long-term (2 year) immunity to re-infection and recognition of local environmental factors (e.g., building ventilation rates, zip code, air quality indicators) that could modify this immunity and assist with protecting the workforce and surrounding community. These results could inform national and global policies.

This is a retrospective, observational study based on the consortium of the SafeBoosC-III randomised clinical trial. This study will evaluate if the number of admitted extremely preterm infants has decreased in the SafeBoosC-III departments during the global lockdown, and whether there is an association between the level of lockdown restrictions and change in the number of ELGAN admissions.

The objectives of this study are to report the response strategy to prevent COVID-19 spread implemented at a Korean medicine hospital, and the satisfaction survey results regarding its preventive measures.
