Clinical Trials and Expanded Access

The purpose of this study is to examine the impact of ascorbic acid (vitamin c) and zinc gluconate in reducing duration of symptoms in patients diagnosed with coronavirus disease 2019 (COVID-19). Patients above the age of 18 who present to the Cleveland Clinic outpatient testing and receive a positive test for COVID-19 will be invited to participate.

INTRODUCTION In critical situations, such as the current COVID 19 pandemic, themes of fear, uncertainty and stigmatization are common and constitute barriers to appropriate medical and mental health interventions. These challenges, when faced by those who live with a chronic disease, such as diabetes mellitus (DM), can negatively influence quality of life and adherence to treatment, compromising the control of the disease. OBJECTIVES The present study aims to investigate the effectiveness of a tele-intervention during the COVID-19 pandemic in improving glycemic control, lipid profile, blood pressure levels and parameters of medication adherence, mental well-being and sleep quality in patients with type 1 DM and type 2 DM. METHODS A randomized clinical trial will be carried out with patients with a previous diagnosis of type 1 DM and type 2 DM, who are registered at the Hospital de Clínicas de Porto Alegre (HCPA). Inclusion criteria will be age greater than or equal to 18 years, collection of HbA1c in the HCPA laboratory in January, February or March 2020 and availability to receive weekly phone calls. Patients will be randomized, stratified by type of diabetes, in two groups: G1: participants will receive a tele-intervention by a case manager weekly to discuss topics related to diabetes management and mental well-being during the social distancing period ; G2: participants will receive the usual care. The primary outcome assessed will be the variation in HbA1c levels comparatively between groups, with or without a tele-guided strategy, after four months of social distancing (or as long as the recommendation of social distancing measures remains). Secondary outcomes will include experiencing confirmation of COVID-19 infection, variation in lipid profile, blood pressure levels and variation in parameters of emotional distress related to diabetes, eating disorders, medication adherence, symptoms minor psychiatric disorders and altered sleep patterns, which will be evaluated with specific and validated scales. According to the sample calculation, 150 patients will be included in the study (92 with type 2 DM and 58 with type 1 DM). Analysis by intention to treat will be performed separately for patients with type 1 DM and with type 2 DM. SCHEDULE The proposed experiment will start immediately after approval of this project by the research ethics committee. The duration of the proposed intervention is 4 months (or as long as the recommendation of social distancing measures remains. This means that the study may be completed before or after that period, based on national recommendations for social distancing in Brazil), with a data analysis plan and publication of the results until September 2020.

During the COVID-19 pandemic several countries have seen a high risk of transmission for health care personnel, with some countries having as many 20-25% of nurses and doctors either infected or showing symptoms of COVID-19. In this prospective cohort study, we will systematically screen all hospital staff in the Capital Region of Denmark for IgM and IgG antibodies against SARS-CoV-2 using a point of care tests and an Elisa kit. Testing will be offered 3 times: In April 2020, Maj 2020 and September 2020. All participants will submit a questionnaire regarding exposures, risk factors and symptoms of COVID-19 in relation to each testing. Follow-up will be through electronic patient records and national registries. We will compare the group of health care personnel with data from a control group of healthy volunteer blood donors from the Danish Blood Donor Study. The aim of the study is to investigate the proportion of hospital staff with SARS-CoV-2 antibodies during the study period compared to a control group representing the Danish population. We will compare the test characteristics of the two methods of testing, a point of care test and Elisa. Further, we will investigate the extent to which prior immunization or infection is protective for future infection with COVID-19.

Summary of the study Study population: A representative sample of the Viennese population stratified by age and gender (data from the Vienna Health Study LEAD) Potential output and analysis: - Extent of age-specific infection and antibody formation - Cumulative incidence of infection - Rate of asymptomatic infection - Relationship with socioeconomics, lifestyle and risk factors (comorbidities) Study design: Prospective, longitudinal, stratified by age and gender Duration of study: Initial testing as soon as possible and repeat based on monitoring of the pandemic curve (probably after 2-3 months) Information to be obtained from participants: - serum samples for information on SARS-CoV2 infection and antibody formation - data on clinical symptoms

Doctors, nurses and staff members of ear-nose and throat (ENT) departments are at high risk due to aerosol-inducing diagnostic procedures and surgery during the COVID-19 epidemic. Reports from China, Spain, Italy and England report of fatal cases among ENT specialists. With a concurrent lack of personal protection, it is of paramount importance to identify patients and healthcare workers at an early stage to prevent a COVID-19 outbreak in the department. A baseline study of all healthcare workers has been performed. Follow-up will be accomplished by interval testing, antibody measurements and REDcap Covid-19 questionnaires. All patients at risk of carrying SARS-CoV-2, or who are candidates for high-risk airway surgery will be tested. Infection control measures at the department will be implemented progressively according to the real-time surveillance results from both patients and healthcare workers.

The purpose of this research is to collect information about coronavirus exposures, symptoms, and health care visits due to the among Atrium Health clients and health care workers. Participation in this study will involve completing a daily questionnaire which covers participants coronavirus illness history or symptoms, health care seeking behaviors and treatments, contact with other sick people, and for health care workers, their use of personal protective equipment.

Purpose: To determine the number of asymptomatic individuals who have antibodies to SARS-CoV-2, the virus which causes COVID-19

The fight against the spread of the 2019-nCoV epidemic has achieved some success in China, but the epidemic is far from over. A key factor making the epidemic under control in China is the government's call for social distance, which has led to few people going out for donation. As a result, the number of blood donors on the streets has been continuing to decline. Urgent recruitment of blood donors is therefore planned during the period from 30 April to 10 May via emergency recruitment SMS . This study has been designed to compare which information extraction frameworks would be more sensitive to blood donors in emergency situations.

According to the data of February 2020, in Turkey with a population of 83.9 million, internet and social media usage percentage to population are 74% and 64% respectively. Although previous researches have investigated the effect of social media on different medical situations, there is no study focused role of social media on patients' behavior and information source during the COVID-19 pandemic. In the present study, it is aimed to reveal the impact of social media on patients' attitudes and information sources during the COVID-19 pandemic.

This investigation is a randomized intervention trial that evaluates behavioral nudges (BN) to increase hand washing behavior and subsequently reduce COVID-19 spreading to a targeted high-risk patient population based in Wisconsin.
