Active clinical trials for "COVID-19"

The main objective of this study is to describe the incidence of thromboembolic events in a population of patients hospitalized in intensive care units in France for severe COVID-19. The secondary objective of this study is to describe the evolution of hemostasis parameters during the first two weeks of intensive care hospitalization and to evaluate the influence of different anticoagulation regimens on these parameters and on the incidence of thromboembolic events

The objectives of this proposal are to: 1) determine the rate of SARS-CoV-2 seroconversion in unselected pregnant women in Hong Kong; 2) determine the rate of SARS-CoV-2 infection in women presenting with miscarriage and stillbirth; 3) follow the pregnancy course and perinatal outcome of confirmed COVID-19-infected pregnant cases; 4) determine the risk and characteristics of vertical transmission; and 5) evaluate the placental barrier, immune response and fetal damage in vertical transmission of SARS-CoV-2. A series of longitudinal and cross-sectional observational studies, and a laboratory-based study will be conducted to fulfil the 5 objectives.

SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), has negatively impacted global health and requires more research to develop better tests and to improve disease treatment. The purpose of this research is to aid in the testing effort by collecting samples from people who have been diagnosed with COVID-19 or are suspected of having COVID-19. Samples you provide will be used investigationally by INanoBio to develop a test to determine when antibodies against various SARS-CoV-2 proteins are detectable. Up to approximately 80 subjects of all ages with either a suspected or lab-confirmed diagnosis of COVID-19 will take part in this research.

The research aims to determine the impact of a syndromic mutiplex PCR assay (FilmArray) on the management of patients hospitalized in ICU for severe respiratory disease. During the SARS-CoV-2 outbreak, the diagnosis of pneumonia has become considerably more complex as the biological, radiological and clinical criteria of covid-19 interfere with the standard criteria for the diagnosis of severe respiratory diseases. Moreover, patients with COVID-19 are at higher risk of developing other associated infections and thus, patients have therefore often been treated with antibiotics, adequately or not, due to difficulty to quickly identify the etiology of their symptoms with conventional methods. In order to improve their treatment, both diagnostic and therapeutic, we set up a new syndromic molecular test in our laboratories to accelerate and improve the pneumonia management and antibiotic stewardship. This research will include 100 to 150 adult patients hospitalized in ICU during the first half of 2020. It will take place within the Nancy University Hospital and the Reims University Hospital, France.

Coronavirus infection is responsible for muscle wasting (sarcopenia), especially during prolonged stays in intensive care. Sarcopenia, in its functional aspect also seems major in patients hospitalized for this infection, in non-ICU unit. Weight loss also appears to be significant, despite a prevalence of overweight and obesity in severe forms. Undernutrition in the obese patient is also possible (undernourished obese and sarcopenia obesity). Anosmia and dysgeusia participate in undernutrition by reducing energy intake. The rehabilitation of these patients requires nutritional support (increased protein intake) associated with progressive retraining to physical activity. An early and proactive management procedure within Coronavirus disease-19 units has been implemented in conjunction with the Transversal Nutrition Unit (TNU). This nutritional care must be continued after discharge. Follow-up by teleconsultation or telephone consultation is put in place after the patient's discharge Primary Objective: Evaluation of nutritional status at the time of admission and discharge and home follow-up in outgoing patients from Coronavirus disease-19 Units Secondary objectives: Description of the evolution of food intake, diversity of food and coverage of needs Evaluation of the muscular strength of the wrist (by grip test in hospital) and on the arms and legs after return home (visual analog scale) Evolution of anosmia and dysgeusia (at the time of hospital admission, at the time of hospital discharge and at home) Level of physical training before infection (IPAQ) Description of the general state of health measured by the performance index - world health organization scale Description of nutritional prescriptions Description of the prevention measures and incidence of Inappropriate Refeeding Syndrome (IRS) Care needs assessments

The Primary objective is to explore ambulance service attendance at incidents involving alcohol and/or substance use over the period of the pandemic lockdown, and the following months. This will be to determine prevalence and explore factors such as patient gender, age, ethnicity or location. Analysis will examine the calls over the course of the year prior to the lockdown, and then compare this to the period of lockdown and following months.

The aim of this questionnaire survey is to evaluate the improvement in vision-related quality of life before and after cataract surgery using the National Eye Institute Visual Function Questionnaire 25 and the delay of improvement in the COVID-19 pandemic.

SARS-CoV-2 is the novel coronavirus responsible for COVID-19, coronavirus disease 2019. This new coronavirus was first detected in Wuhan, China in late December 2019. According to WHO, the incidence rate of COVID-19 is prominent among adults and elderly people, reaching so far >2 million cases globally. Meanwhile, confirmed death cases reached >126 thousands of reported cases in 185 countries and still increasing. We anticipate that immunological differences among COVID19-infected patients might be a reason behind the variation of patient outcomes. Therefore, we intend to investigate cellular and humoral immune responses of COVID19-positive patients, and we claim to discover new indicators of patients' prognosis. Our target population includes three categories of patients staying at ICU, HMC (COVID19-positive vs. COVID19-negative vs. healthy control). Throughout their ICU stay, multiple blood samples will be screened for leukocytes surface markers, leukocytes' production of certain molecules, and circulating cytokines/chemokines/checkpoint inhibitors. Their plasma/serum will be used as well for immune proteomics, metabolomics, and other serological tests. Such parameters can provide the more comprehensive status of COVID19-infected patients at infection onset, during treatment intake, and at recovery or relapse stage. Following analysis, the main prospective outcome of this study is to identify the most reflective markers of COVID19-positive patients' outcomes.

Coronavirus infection, also known as COVID-19, has become a global pandemic with over 3 million cases and 250,000 deaths worldwide. Coronaviruses (CoV) belong to a family of viruses that predominately infect mammals and birds, affecting their lungs, intestinal tract, liver and nervous systems. Prior to the discovery of the current novel coronavirus strain (SARS-CoV-2), there were six different strains that are known to infect humans, which includes the virus that caused the severe acute respiratory syndrome (SARS) pandemic in 2002. In humans, the majority of severe illness from SARs and COVID-19 is due to inflammation of the lungs and pneumonia. Pregnancy poses a significantly increased risk of viral pneumonia and during SARS more pregnant women required intensive care and breathing support, and the proportion of deaths was higher when compared to non-pregnant adults. Furthermore, kidney failure and development of abnormal blood clotting disorders, which occurs during severe infection, is more common in pregnancy and the associated changes in blood vessels extend to the placentas of infected pregnant women, thus potentially affecting the fetus. This makes pregnant women affected by the virus at high risk of developing severe complications. Fortunately, there have been a number of biomarkers identified that are associated with illness severity. These include, specialised white blood cells, blood clotting cells and constituents, as well as other measures of heart and kidney function. We propose that these biomarkers are important correlates of clinical disease severity and prognosis in pregnant and postnatal women. This knowledge has the potential to help clinicians during this pandemic to better manage and care for their patients.

The TRANSCOV cohort is a multicentre observational retrospective study aiming at assessing the health impact of extra regional transfers of critically ill COVID-19 patients.
