COVID-19 Clinical Trials and Expanded Access

The Coronavirus has caused containment of more than a third of the world's population. Containment can drastically change lifestyle habits, including eating habits such as the number of meals, meal times or their composition. However, there is currently no data on the influence of confinement on eating habits.

Bone and soft tissue sarcomas represent about 7-12% of all pediatric cancer and are a heterogeneous group of tumors arising in connective tissues embryologically derived from the mesenchyme. For some of these tumors relapse and mortality rates are still significantly high. Therefore, further studies are needed to better understand pathogenetic processes underlying sarcomas to offer new and more effective treatments. Next generation sequencing (NGS) has opened new frontiers for cancer research allowing to identify somatic or constitutional mutations known or yet unknown with the aim to better understand carcinogenesis. The establishment of the genomic profile of the tumor could also help clinicians to personalize patients treatment based on their genetic and molecular alterations.

The main objectives of this study are 1. to establish the prevalence of SARS-CoV-2 in schools and kindergartens in the State of Mecklenburg-Vorpommern in autumn and winter 2020/2021 2. to monitor the future spread of the disease by assessing serological responses to SARS-CoV-2 in teachers and childcare educators over time

The Severe Acute Respiratory Syndrome COronaVirus 2 (SARS-CoV2) is a new and recognized infectious disease of the respiratory tract. Around 20% of those infected have severe pneumonia and currently there is no specific or effective therapy to treat this disease. Therapeutic options using malaria drugs chloroquine and hydroxychloroquine have shown promising results in vitro and in vivo test. But those efforts have not involved large, carefully-conducted controlled studies that would provide the global medical community the proof that these drugs work on a significant scale. In this way, the present study will evaluate the effectiveness and safety of the use of hydroxychloroquine combined with azithromycin compared to hydroxychloroquine monotherapy in patients hospitalized with pneumonia by SARS-CoV2 virus.

Coronavirus Disease 19 (COVID-19) represents an unprecedented challenge to the operations and population health management efforts of health care systems around the world. The "Pandemic Research Network (PRN): Duke Community Health Watch" study leverages technology, clinical research, epidemiology, telemedicine, and population health management capabilities to understand how to safely COVID-19. The target population is individuals in the Duke Health region as well as individuals beyond the Duke Health region who have flu-like symptoms, a viral test order for COVID-19, confirmed COVID-19, or concern for exposure to COVID-19. A subgroup of particular interest within the target population is health care workers (HCW) and families of HCW. Community members will enroll in the study electronically and for 28 days will be reminded via email or SMS to submit signs and symptoms related to COVID-19. Participants who report symptoms will be provided information about COVID-19 testing (if needed) and established mechanisms to seek care within Duke Health. Instructions for telemedicine and in-person visits, which is available publicly at https://www.dukehealth.org/covid-19-update, will be presented to participants. Participants who are unable to report symptoms independently may be contacted via telephone by Population Health Management Office (PHMO) or Clinical Events Classification (CEC) team members. Data collected through the "Pandemic Response Network (PRN): Duke Community Health Watch" study will be used for three objectives. - First, to characterize the epidemiological features of COVID-19. Specifically, we will have a high-risk subgroup of HCW and families of HCW that we enroll. - Second, to develop models that predict deterioration and the need for inpatient care, intensive care, and mechanical ventilation. - Third, to develop forecast models to estimate the volume of inpatient and outpatient resources needed to manage a COVID-19 population. The primary risk to study participants is loss of protected health information. To address this concern, all data will be stored in Duke's REDCap instance and the Duke Protected Analytics Compute Environment (PACE).

Hypothesis Very recent evidences supports the hypothesis that the novel coronavirus 2019 (2019-nCoV) uses the SARS-1 (severe acute respiratory syndrome ) coronavirus receptor angiotensin converting enzyme 2 (ACE2) for entry into target cells. The epidemiological association between Angiotensin receptor-blocker (ARB) or ACE inhibitors (ACE-I) use and severe sequelae of 2109-nCoV infection disease COVID-19 has not been yet conclusively demonstrated, but may have important consequences for population health. Aim To retrospectively test whether 2019-nCoV patients treated with ACE-I or ARB, in comparison with patients who not, are at higher risk of having severe COVID-19 (including death). Population Hospitalized patients with confirmed COVID-19 infection (any type). Study design Patients will be divided in two groups, a) controls: individuals who did not develop severe COVID-19 respiratory disease (including individuals who recovered from the infection) and b) cases: individuals who developed severe COVID-19 disease (including fatal events). Treatment with ACE-I or ARB, together with possible confounding will be assessed retrospectively. Exposure Treatment for ACE-I or ARB.

The purpose of this study is to test the hypothesis that post-exposure prophylaxis with hydroxychloroquine will reduce the symptomatic secondary attack rate among household contacts of known or suspected COVID-19 patients.

Collection and analysis of demographic, clinical, radiographic and laboratory characteristics of CoViD-19 patients to identify predictors of disease severity, mortality and treatment response, and to identify subgroup of patients that might benefit from specific therapeutic interventions

COVID-19 outbreak is often lethal. Mortality has been associated with several cardio-vascular risk factors such as diabetes, obesity, hypertension and tobacco use. Other clinico-biological features predictive of mortality or transfer to Intensive Care Unit are also needed. Cases of myocarditis have also been reported with COVID-19. Cardio-vascular events have possibly been highly underestimated. The study proposes to systematically collect cardio-vascular data to study the incidence of myocarditis and coronaropathy events during COVID-19 infection.We will also assess predictive factors for transfer in Intensive Care Unit or death.

The purpose of this study is to test the effect of purified (acellular) amniotic fluid as a treatment for SARS CoV-2 (COVID19)-associated respiratory failure. Past use of human amniotic products (i.e., membrane and fluid) is FDA-approved for tissue injury and has been used to reduce inflammation and fibrosis in patients with a variety of medical conditions. The investigators hypothesize that using nebulized and/or intravenous purified (acellular) amniotic fluid will reduce both inflammation in patients hospitalized for in SARS CoV-2 (COVID19)-associated respiratory failure, potentially leading to a decrease in respiratory support.
