Active clinical trials for "COVID-19"

A randomized parallel double-blinded placebo-controlled clinical trial to evaluate the effect of Emtricitabine/Tenofovir alafenamide (FTC/TAF) compared with placebo on the risk of developing SARS-CoV-2 disease (COVID-19) in healthcare workers with high transmission risk in addition to currently recommended control measures.

Coronavirus disease 2019 (abbreviated "COVID- 19") is a pandemic respiratory disease that is caused by a novel coronavirus and was first detected in December 2019 in Wuhan, China. The disease is highly infectious, and its main clinical symptoms include fever, dry cough, fatigue, myalgia, and dyspnoea.1 In China, 18.5% of the patients with COVID-19 developed to the severe stage, which is characterized by acute respiratory distress syndrome, septic shock, difficult-to-tackle metabolic acidosis, and bleeding and coagulation dysfunction. After China, COVID-19 spread across the world and many governments implemented unprecedented measures like suspension of public transportation, the closing of public spaces, close management of communities, and isolation and care for infected people and suspected cases. The Malaysian government had enforced Movement Control Order (MCO) from 18th March to 4th May 2020 and henceforth Conditional Movement Control Order (CMCO) until 9th June 2020. The battle against COVID-19 is still continuing in Malaysia and all over the world. Due to the CMO and CMCO in the country, public and private universities have activated the e-learning mode for classes and as the government ordered, universities are closed and no face-to-face activities allowed. This has forced students of all disciplines including dentistry to stay at home which are wide-spread across Malaysia and shift to e- learning mode. To guarantee the final success for fight against COVID-19, regardless of their education status, students' adherence to these control measures are essential, which is largely affected by their knowledge, attitudes, and practices (KAP) towards COVID-19 in accordance with KAP theory. Once the restrictions are eased students have to come back and resume their clinical work in the campus. Hence, in this study we assessed the Knowledge, Attitude, and Practice (KAP) towards COVID-19 and the students preference for online learning.

The purpose of this study is to learn more about the acute response to infection with and recovery from the virus called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Some people know this virus by the name "coronavirus." It can cause the disease called COVID-19. The information gained from the study can be used to help develop better tests for SARS-CoV-2 infection and COVID-19 disease and may help in developing future vaccines, other prevention strategies, and treatments.

More cases of COVID-19 pandemic are being reported daily around the world. It is highly infectious and, over 7 million people have been infected and more than 400,000 people have died globally till this date. Countries around the world are struggling to avoid the spread of this pandemic. Center for Disease Control and Prevention (CDC) confirmed that there are no approved drugs for COVID-19 treatment. Researchers around the globe, however, are researching different medications for COVID-19 patients, including the drug Hydroxychloroquine (HCQ), which is mainly used for Rheumatoid Arthritis and Malaria. Not enough data was obtained yet to know how well all of these medications are functioning. Therefore, aim to perform a randomized placebo-controlled trial to assess the impact of these medications on COVID -19 healthcare workers exposed while treating COVID 19 patients in Qatar to avoid causality and comorbidities in healthcare workers. It is considered as a weak base. Many viruses enter the host cells via endocytosis, as a result of which they are initially taken up into an intracellular compartment that is "typically fairly acidic" whereas; Hydroxychloroquine would alter the acidity of this compartment, which can interfere with the ability of viruses to escape into the host cell and start replicating. Another hypothesis on the rationale of the Antiviral activity of HCQ, is that HCQ may also alter the ability of the virus to bind to the outside of a host cell in the first place. An interventional, double-blind, placebo-controlled randomized trial that will include participants who will be healthcare workers at risks of exposure to COVID-19 while managing patients with confirmed infection. Study will compare the safety, efficacy and effectiveness of Post Exposure Prophylaxis (PEP) use of HCQ in healthcare workers at risk of exposure to COVID-19 patients, in comparison to Placebo in Qatar.

Background: The rapid spread and high infectivity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) makes identifying an effective prophylaxis agent highly important. One of the important target populations for such intervention who are at high risk of exposure are health care workers (HCWs) who may develop disease and/or expose patients and other HCWs. Hydroxychloroquine (HCQ), currently in usage for treatment of severe Coronavirus Disease 2019 (COVID-19), has in addition to in-vitro activities of inhibition of virus replication and immunomodulation, an important role in the inhibition of pre-entry step of the virus to host cells. Such activity in the early stage of infection may play a role in prevention of disease progression. Objectives: To evaluate the effect of HCQ in prevention of clinical disease and reduction of viral shedding among HCWs following exposure to confirmed COVID-19 patients. Study design: Multi-center, randomized controlled, superiority, open label trial Setting: The study will be conducted at Rambam Health Care Campus. Eligibility: Participants eligible for inclusion will include non-pregnant adult (>18 years old) HCWs who were exposed to a confirmed case of COVID-19 without full adherence to droplet precautions. Participants will be eligible in a period no longer than 72 hours after exposure. Intervention: HCQ will be given in the intervention group in a dosage regimen of 400mg BID in the first day followed by 200mg BID for overall 10 days. Participants in the control group will receive no treatment. Treatment will be started no longer than 72 hours following exposure. Outcomes: The primary outcome will be the number of participants who develop clinical signs compatible with COVID 19 (defined in full protocol) within 14 days of exposure. Secondary outcomes will include virologically-confirmed COVID 19, disease severity (need for hospitalization, mechanical ventilation and 30-day mortality) and viral shedding duration (time between first positive PCR to last of two consecutive negative tests) for confirmed COVID 19 cases. Sample size: The trial will test for HCQ's superiority assuming a primary outcome incidence of 20% in the control group and a reduction of 50% with HCQ. The sample size required for a power of 80% (alpha 0.05) is 291 participants per each group.

The current COVID-19 pandemic has affected more than 3 million people worldwide across more than 200 countries. In the United Kingdom alone, at the end of April, there were almost 160,000 confirmed cases with more than 20,000 deaths. This has undoubtedly had significant physical and economical impact on the public. Healthcare workers are at high risk of developing life-threatening infectious diseases with increased exposure to patients' blood and bodily fluids. As such, health care workers arguably experience heightened anxiety and are predisposed to greater negative psycho-social impact from the current COVID-19 pandemic. The aim of this study is to evaluate the physical and psychological impact of COVID-19 on healthcare workers. This will be performed in two phases. In phase 1, investigators will collect information to evaluate the current psychiatric symptom profile (in particular, screening for anxiety or depression related symptoms), alcohol use, sleep-related complaints and overall well-being among healthcare workers who participate in this survey (with a focus on junior doctors). In addition the association of these mental health and behavioural parameters with the prevalence of stressful occasions, such as long-hours, unpredictability of work / redeployment, availability of personal protection equipment and concerns regarding family/relationship and self will be assessed. In phase 2, investigators will then reassess for the development or progression of psychiatric symptoms, use of alcohol and other substances, behavioural or interpersonal relationship changes as well as physical well-being at 6 weeks and 4- months. Physical well-being is assessed through the presence of suspected or confirmed COVID-19 infection and absence from work. Specifically, investigators will study the impact of variable provision of personal protection equipment (supply and training), extended working hours, and concern for well-being of family members, on work morale and anxiety levels. Another aim is also study the longer term mental health consequences of the current pandemic on health care workers.

COVID19 is a worldwide pandemic. Hence SARS-CoV-2 is a novel virus; there is no specific medication against it. Like other countries of the world, Bangladesh is also struggling in the case of treatment of this disease. Besides antiviral drugs other existing drugs like Hydroxychloroquine, Chloroquine, and recently Ivermectin has been used for the treatment of mild to moderate cases of COVID19 disease. Till now Hydroxychloroquine has shown a good effect. Recently anti-parasitic drug Ivermectin was found highly effective in an in-vitro study against SARS-CoV-2. This study is aimed to evaluate the efficacy of Ivermectin and Hydroxychloroquine as a combination therapy with antibiotics (Doxycyclin and Azithromycin) and compare the recovery period of these two drugs applied as core monotherapy.

The purpose of this study is to assess the safety and efficiency of an assembled modified mask in protecting health care workers against Coronavirus in case of any personal protective equipment shortage. At least 20 healthy participants will be recruited to try the modified mask. The modified masks will be made from masks that are already available as well as filters available in the pulmonary department at the Oklahoma City VA Health Care System

Background: Sickle cell disease (SCD) is a chronic illness. It affects about 100,000 people in the United States. People with SCD have red blood cells that are sickle-shaped and impaired in their function. This results in a lifetime of complications that affect every organ system. People with SCD also are at greater risk for respiratory infections and lung problems. Researchers want to study how this population s stress, anxiety, fear, pain, sleep, and health care use are being affected by the COVID-19 pandemic. Objective: To study the extent and impact of life changes induced by the COVID-19 pandemic on people living with SCD in the U.S. Eligibility: People age 18 and older with SCD who live in the U.S. Design: Participants will complete a survey online. The questions will focus on the following: Medical history Mental and physical health Demographics Stress Resilience Health care use COVID-19 Beliefs about medical mistrust and participation in research. At the end of the survey, participants will be asked if they would like to take the survey again in the future. If they reply "yes," then they will be contacted by the study team in 6-9 months to take the survey again. They may complete the survey again in 6-8 months, 12-15 months, and 18-21 months. The survey should take less than 40 minutes to complete. Participants' data will be coded to protect their privacy. The coded data may be shared with other researchers.

Subjects will be recently discharged patients from Sunnybrook Inpatient Psychiatry Unit. Subjects will be randomized in a 1:1 ratio to either the Caring Contact intervention or usual care. 75 subjects will be enrolled in each arm. In additional to usual discharge-related care, subjects in the caring contact group will receive brief emails that convey a message of hope and provide resources. These emails will be sent on days 4, 21, and 56 post-discharge. The specific content of these emails will be pre-determined varying slightly by time point. In contrast, the control group will only receive usual discharge-related care, including discharge planning and also a sheet of resources normally provided to patients. A widely used and validated measure will be employed to assess depression and anxiety symptoms. The 25-item self-report Hopkins Symptom Checklist will be emailed to all subjects at baseline, day 4, 21, and 56 post-discharge, along with the Caring Contact communication. It is hypothesized that there will be a significantly greater reduction in mental health symptoms among patients receiving Caring Contacts compared to those who receive usual care.
