Reduction in COVID-19 Infection Using Surgical Facial Masks Outside the Healthcare System
COVID-19In the current COVID-19 pandemic with coronavirus, SARS-COV2, the Danish Health Authorities recommend using facial masks in the health care system when handling patients presumed or proven to be infected with the virus. However, the use of facial masks outside the health care system is not recommended by the Danish Health Authorities. Here, Health Authorities in other countries have different recommendations for the use of facial masks. Challenges when using facial masks outside the health care system include wearing the mask consistently, an efficacy of the mask of app. 8 hours necessitating a change of mask throughout the day, and that it is not sufficiently tight enough to safely keep the virus out. Moreover, the eyes (mucous membrane) remain exposed. Compliance could also be another challenge. SARS-COV2 is assumed to primarily enter the body via the mouth through respiratory droplets - or possibly through inhalation of aerosol containing the virus. From the mouth the virus is assumed to spread to the airways and the gastro-intestinal tract. SARS-COV2 is also known to be transmitted via physical contact, helped along by the fact that the virus can survive on surfaces for at least 72 hours. Touching such a contaminated surface can transfer the virus to the mouth via the hand - and thus lead to infection of the person. Facial masks are expected to protect against viral infection in two ways; By reducing the risk of getting the virus in via the mouth or nose via respiratory droplets or aerosol By reducing the transfer from virus-contaminated hands to the mouth or nose Hypothesis The use of surgical facial masks outside the hospital will reduce the frequency of COVID-19 infection. All participants will follow authority recommendations and be randomized to either wear facial masks or not. The participants will be screened for antibodies at study start and study end. They will perform swab-test if they experience symptoms during the study as well as the end of study.

Clinical Trial of Allogeneic Mesenchymal Cells From Umbilical Cord Tissue in Patients With COVID-19...
COVIDThe disease caused by the SARS-CoV-2 virus is a viral disease that infects the lungs, producing flu-like symptoms. Elderly infected patients and/or those with co-morbidities may suffer from acute respiratory distress syndrome due to pneumonia (COVID-19 disease). Given the high transmission, this virus has spread in recent months from Wuhan (China) to the whole world, becoming a global emergency pandemic. The lack of curative treatment for this disease justifies the need to carry out clinical trials that provide quality evidence on treatment options. Given the pathophysiology of the disease, which involves an uncontrolled inflammatory response of alveolar cells, a treatment that attenuates the cytokine cascade could be key in rescuing the patient's lung tissue. Mesenchymal cells, due to their immunoregulatory potential and regenerative capacity, can be an effective treatment for patients infected with the SARS-CoV-2 virus. In the present study we propose a therapy with undifferentiated allogeneic mesenchymal cells derived from umbilical cord tissue, a treatment whose safety has already been described in other clinical trials and that shows promising results in pilot studies carried out in China.

MK-5475 in Participants With Hypoxemia Due to COVID-19 Pneumonia (MK-5475-009)
Coronavirus Disease 2019 (COVID-19)Pneumonia1 moreThe purpose of this study is to evaluate safety, tolerability, and pharmacodynamics of MK-5475 after administration of multiple doses to participants with COVID-19 pneumonia. The primary hypothesis is that MK-5475 when administered to participants with COVID-19 pneumonia and hypoxemia improves arterial oxygenation as measured by the ratio of blood oxygen saturation to fraction of inspired oxygen (SpO2/FiO2 ratio) compared to placebo.

COVID-19 Anticoagulation in Children - Thromboprophlaxis (COVAC-TP) Trial
Infection ViralThromboses2 moreThe purpose of this study is to evaluate the safety, dose-requirements, and exploratory efficacy of twice-daily subcutaneous enoxaparin as venous thromboembolism prophylaxis in children (birth to 18 years) hospitalized with signs and/or symptoms of SARS-CoV-2 infection (i.e., COVID-19).

COVID-19: Povidone-Iodine Intranasal Prophylaxis in Front-line Healthcare Personnel and Inpatients...
COVID-19SARS-CoV 2Povidone-iodine (PVP-I) is a broad-spectrum antiseptic with activity against bacteria, fungi, and viruses. It has been previously used in both intranasal preparations against Methicillin Resistant Staphylococcus Aureus (MRSA) as well as oral preparations in in-vitro studies of Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV), Middle Eastern Respiratory Syndrome Coronavirus (MERS-CoV), influenza H1N1, and rotavirus with good efficacy. This study will evaluate the efficacy of PVP-I as prophylaxis in Coronavirus Disease 2019 (COVID19)-negative front-line health care workers, hospital patients, and community members.

Hydroxychloroquine Azithromycin COVID-19 Pregnancy Trial
COVID19Up to date, and since December 31st 2019, 2 520 522 cases of COVID-19 including 176 786 deaths, have been reported worldwide. Global efforts are made to save lives and decrease morbidity by evaluating therapeutic strategies. Pregnant women with COVID-19 are at high-risk of severe complications and mortality from COVID-19 infection, due to physiologic and immune changes occurring during pregnancy. These risks include development of maternal hypoxemic respiratory failure due to severe pneumonia, hospitalization in intensive care, death; but also, fetal morbidity-mortality with chronic and/or acute fetal distress, intrauterine growth retardation, intrauterine death and neonatal morbidity, mainly due to induced preterm birth and maternal-fetal transmission. Knowledge of these epidemiologic facts on SARS-Cov-2 infection in pregnant women is currently limited to small case-series. No drug has demonstrated solid evidence in treating SARS-Cov-2 virus. Nevertheless, in vitro studies and tests in COVID-19 positive patients treated with hydroxychloroquine and azithromycin merit further evaluation. Pregnant women are systematically excluded from drug trials, and treatment options for this high-risk population remain untested. The aim of this study is to screen pregnant women presenting minor symptoms, for COVID-19 and to evaluate efficacy of hydroxychloroquine-azithromycin treatment in preventing aggravation of symptoms with development of hypoxemic respiratory failure and complications of pregnancy.

Hydroxychloroquine Treatment of Healthcare Workers With COVID19 Illness at Montefiore
COVIDCoronavirus1 moreGiven the high prevalence of COVID19 illness (both SARS-CoV-2 RT-PCR confirmed and highly suspect cases) among healthcare workers (HCW) within the Montefiore Health System (MHS), hydroxychloroquine (HCQ) will be prescribed to healthcare workers who are at the highest risk for severe COVID19 illness.

COVID-19: Nasal and Salivary Detection of the SARS-CoV-2 Virus After Antiviral Mouthrinses
COVID19Mouthwash1 moreGiven the current lack of effective COVID-19 treatment, it is necessary to explore alternative methods to contain the spread of the infection, focusing in particular on its mode of transmission. The modes of person-to-person transmission of SARS-CoV-2 are direct transmission, such as sneezing, coughing, transmission through inhalation of small droplets, and transmission through contact, such as contact with nasal, oral and eye mucous membranes. SARS-CoV-2 can also be transmitted directly or indirectly through saliva. The use of antiviral mouthrinses may be used as adjunctive therapy.
