Active clinical trials for "COVID-19"

many patients with confirmed infection with COVID-19 suffer from different symptoms and signs of gastrointestinal symptoms

This multicentre prospective study will enroll a sufficient number of patients to afford approximately 30 positives and > 30 negatives (as determined by the SOC - Comparator method) in the United States and/or Canada. One to three sites in the Canada will participate over an approximate 6-week enrolment period. The actual enrolment period will be dependent upon prevalence of Covid-19, and site set up. Once positives sample size is achieved, expected SARC-CoV-2 negative subjects will be permitted. Once subjects are consented and recruited for the study, up to three (3) study-specific nasopharyngeal samples for each patient will be collected by trained operators at the clinical site: a single SOC swab, and two (2) Spartan swabs where the second swab is optional and used when the first Spartan swab test does not produce a positive or negative result ("inconclusive"). The first swab sample will be tested at the clinical site according to standard of care protocols currently in place for the sites' nasopharyngeal swab-based SARS-CoV-2 RT-PCR testing. The second nasopharyngeal sample will be tested at the site using the Spartan COVID-19 v2 System. A third, optional nasopharyngeal sample, if collected, will be tested using the Spartan COVID-19 v2 System only when the test conducted with the second nasopharyngeal swab does not produce a positive or negative result.

The objective of the study is to identify socio-demographic factors, behaviors and practices associated with infection with SARS-CoV-2 to help determine where and how patients mostly get infected with SARS-CoV-2. It is a case-control study including : cases identified by the nationwide system of positive SARS-CoV-2 tests (COVID-19 diagnosis information system, SIDEP) (currently limited to qRT-PCR) and invited to participate by the National Health Insurance (CNAM) which hosts the data from the nationwide test system; controls included via Ipsos, a polling institute with access to personal data from a panel from which they will include controls matched on age (divided into 10-year categories), gender and geographic area (departement); cases will be offered to invite a person they live with to participate in the study offering another case-control analysis inside a household. These participants will be required to report the result of the test as recommended by contact tracing guidelines to determine whether they are cases or controls. Data will be collected via a self-administered online questionnaire. Some of the participants will be called for a complementary telephone questionnaire to measure reliability of online retrieved data and explore more specific aspects of SARS-CoV-2 transmission.

Patients requiring hospitalization due to COVID-19 pneumonia (non-severe) will be randomized to standard prophylactic doses or full therapeutic dose of bemiparin (a LMWH) for 10 days.

A fixed cohort of adults in rural Kimpese will be followed up every two months since they are assumed to be at above average risk of contracting COVID-19. Every two months these individuals will be interviewed with a focus on COVID-19 related symptoms and possible exposure to the disease and have their temperature recorded. A social mixing survey will also be carried out to assess human contact behaviour. The data generated will help inform mathematical modelling that can predict which proportion of the population per age group is likely to get infected once COVID-19 is introduced in this rural population, and the epidemic size if no intervention, as well as when targeted interventions are introduced. During the outbreak, physical distancing measures could be implemented. The monitoring of social contacts, again using a social-mixing survey, will contribute to the understanding of the impact of such measures in a rural context on transmission of SARS-CoV-2. The results from the seroprevalence over time, will be used to refine and validate the predictions from the modelling results, (re)calibrate the model where needed, and test hypotheses on transmission-dynamics of COVID-19. In case of an established epidemic of Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the Health Zone of Kimpese, the sero-surveillance will be extended from an assumed high risk cohort to a representative sample of the overall population. Moreover, support to the COVID-19 control measures will be provided by the study team. The national guidelines recommend household transmission investigation for the first 100 confirmed laboratory cases. During the household visit, information on symptoms and one serum sample will be requested of all household members of the index case. If household members are present with symptoms and fever, the COVID-19 outbreak team of Kimpese will provide diagnostic testing and medical care.

Coronavirus disease 2019 (COVID-19), declared by the World Health Organization (WHO) as a "public health emergency of international concern" (January 31, 2020), has posed a significant threat to global health. This infectious disease, caused by the 'severe acute respiratory syndrome coronavirus-2'(SARS-CoV-2), was first reported in China at the end of 2019. As other coronaviruses, SARS-CoV-2 primarily targets the human respiratory system. The most common symptoms are fever, fatigue, and dry cough. During the second week of the disease, part of patients may progress to shortness of breath, then hypoxemia and severe pneumonia. Acute respiratory distress syndrome (ARDS), linked to some risk factors such as advanced age and underlying comorbidities (hypertension, diabetes, cardiovascular disease, and cerebrovascular disease), may be fatal and needs early supportive therapy and monitoring. Some patients with COVID-19 experienced neurological complications including headache, dizziness, hypogeusia and/or anosmia, altered level of consciousness, strokes, seizures, and ataxia, less frequently neuromuscular disorders (NMD) such as acute inflammatory polyradiculoneuropathy. Among NMD, myasthenia gravis (MG) patients, particularly susceptible to infections causing crises, could be of special risk of COVID-19 ARDS. Some general recommendations were established for the management of NMD during the COVID-19 pandemic,with also specific recommendations for MG. However, only data on a small number of patients who were managed in hospital are currently available;in addition, only two cases of myasthenic crisis following COVID-19 were reported. For this reason, the French neuromuscular rare disease network (FILNEMUS: 'FILière NEuroMUSculaire') has created the 'CO-MY-COVID register' to describe the clinical course and prognosis of patients with COVID-19 and pre-existing myasthenic syndrome.

The number of new Coronavirus-2019 (Covid-19) cases is increasing day by day despite the warnings "Stay at home! Wear a mask! Keep social distance!". The aim of this descriptive study is to determine the risk factors that affect the Covid-19 infection in Turkey. The online link of the form created on Google forms was sent to the participants' phones between 18.10.2020 and 18.11.2020.

The aim of this screening protocol is to assess volunteers for their potential eligibility to participate in a dose finding human experimental infection study in healthy subjects using a GMP-produced SARS-CoV-2 wild type strain

Assessment of cause of Death in home Healthcare residents in Östergötland County, Sweden, who had a positive COVID-19 diagnosis and died between March and September 2020. Our aim is to evaluate the pattern of comorbidity and frailty in a group of individuals in home healthcare with positive COVID-19 diagnoses who had a fatal outcome, and a second aim is to assess the contribution of COVID-19 to those fatal outcomes.

Screening programs have been associated with a substantial reduction in colorectal cancer (CRC) mortality through endoscopic resection of preneoplastic lesions and detection of early-stage invasive cancers. In March 2020, the World Health Organization declared as a pandemic the outbreak of coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2. Since then, the SARS-CoV-2 have never stopped spreading, causing an unprecedented situation with highly restrictive considerations to be adopted by the majority of countries worldwide. Health-care facilities have been making an enormous effort to assist patients affected by COVID-19, while adopting measures to maintain a safe environment for patients and healthcare professionals. As a result, the usual workflow in endoscopy departments changed dramatically, leading to an increase in cancelled procedures, probably increasing the future burden of Colorectal Cancer due to delays in diagnosis.
