Active clinical trials for "COVID-19"

A. Primary objective Identifying risk factors for peri-operative complications in patients who have had COVID-19. B. Secondary objectives Identifying peri-operative complications in patients who have had COVID-19. Follow-up of peri-operative complications during hospitalization. Identifying the safe distance at which a patient can be operated after a Sars CoV2 infection without having an increased risk of peri-operative complications. C. Study inclusion and exclusion criteria Inclusion criteria Patients should be included if: are scheduled for elective cardiac surgery with extracorporeal circulation (bypass); they give their consent for their data to be included in studies; Exclusion criteria Patients should be excluded if: they have emergency surgery; have had Sars Cov 2 infection more recently than 3 months; D. Data Collection It is done in an excel table. Data collection is done anonymously. No patient-identifying data will be collected. The collected data will be about comorbidities, COVID-19 status - disease and vaccination, postoperative complications.

The aim of our cohort is to collect prospectively, in a standardized and exhaustive manner, the health data of patients referred to the CAPCoV, our holistic referal post covid clinics for post-covid condition in order to be able to identify typical profiles of patients suffering from post covid syndrome and to follow the evolution of their disease over time.

Over than 30% individuals with COVID-19, including the asymptomatic ones, and around 80% of patients hospitalized with COVID-19 may experience post-COVID sequelae, which is commonly referred to as Long COVID Syndrome. This condition has ties to decreased cognitive function and may lead to neuropsychiatric disorders but still need to be studied further. Using a cross-sectional design, this study will analyze the relationship between cognitive function and neuropsychiatric disorders with brain wave activity in Long COVID patients. The investigators conducted assessments utilizing the quantitative electroencephalogram (qEEG) measurement method and interviews using instruments such as the MMSE MOCA, mini ICD 10, and SF 36. With this qEEG examination, the investigators hoped that there will be an imbalance/abnormality of brain wave activity that arises related to impaired cognitive function.

Started on January 9, 2020 with the announcement of the discovery of a new SARS-CoV-2 coronavirus, the Covid-19 pandemic is responsible as of June 21, 2020 for 160,377 confirmed cases in France, 29,640 deaths and 9,823 hospitalizations. The Grand Est region is one of the regions in France that was most precociously and strongly affected by the epidemic, in particular the Strasbourg University Hospital. Faced with the heavy use of the healthcare system, hospital staff of all categories are an essential resource to be preserved. Several studies have shown the significant impact of Covid-19 on doctors and caregivers. In order to better protect these personnel and avoid contamination that could be harmful to their health but also because of the consequences in terms of staff, it is necessary to better understand the risk factors for transmission of this infection, the means of protection, the evolution of the disease and the determinants of the return to work. Few studies have explored on such a large workforce and in detail the professional risk factors for developing Covid-19 within different groups of hospital professionals including also non-caregivers and the evolution when returning to work in an outpatient population.

The Study objective is to measure retinal neurovascular coupling and blood flow parameters in patients previously infected with COVID-19, long COVID-19 and healthy age- and sex- matched control subjects

The Grand Est region is one of the most affected regions in France during the first wave of the COVID-19 epidemic. A significant increase in the number of patients hospitalized for SARS-CoV 2 infection at the University Hospitals of Strasbourg (HUS) led to a sudden saturation of their capacities. Hospital workers appear to be a population at particular risk for this new infectious agent. The percentage of hospital workers who have been in contact with the virus or have contracted COVID-19 is unknown. The objective of this work is to determine the prevalence of SARS-CoV-2 positive serologies among hospital staff screened from June 22, 2020 to November 1, 2020 following a screening campaign offering serological testing to all volunteer HUS professionals.

The Peking University Health Cohort in Anning, Yunnan (PKUHC-AN) is a prospective cohort study carried out in Anning, Yunnan. The primary aim of this study is to investigate the impact of COVID-19 on older adults' health, and to provide high-quality evidence of real world research for the optimization of prevention and control strategies of COVID-19 and other emerging infectious diseases. Data will be collected regarding health status, history of COVID-19 infections and vaccines, lifestyle and socioeconomic characteristics, as well as the short- and long-term health outcomes.

Data on the use of convalescent plasma in the treatment of covid-19 are scarce: the results of randomized studies involving mainly immunocompetent patients are disappointing, while case series or retrospective data on more selected patients , in particular immunocompromised patients suggest a benefit in these patients whose clinical manifestation seems essentially related to the uncontrolled infection and not the cytokine storm.

The goal of this observational study is to investigate the role fibroblasts play in the persistent respiratory complaints after a COVID-19 infection. Fibroblasts are involved in tissue remodeling and repair by creating scar-tissue (fibrosis) after tissue damage has occurred. The hypothesis is that this process of fibrosis is ongoing in patients with persistent complaints. To evaluate the roll of fibroblasts a new type of scan is used that is capable of imaging active fibroblasts, a 68Ga-FAPI PET/CT scan.

The aim of the study is to make an accurate assessment of immune cells obtained from nasal mucosa and peripherial blood of MIS-C patients during the disease and the period of health.
