Active clinical trials for "COVID-19"

COVID-19 is affecting the people around the world and the infected individuals' may either stay asymptomatic or present to hospitals with severe distress and life threatening symptoms. The objective of the study is to investigate role of Prone positioning and alternate nostril breathing in patients with Covid-19.

Comparison of COVID-19 disease course in hospitalized patients infected by SARS-CoV-2 in first and second waves of the novel coronavirus infection

The main clinical manifestation associated with SARS-CoV-2 infection is an influenza-like illness that follows the infection of the respiratory tract. In a few percent of infected people, inflammation of the lungs leads to severe pneumonia that requires hospitalization, in intensive care units for the more severe cases. Despite intensive care, a fatal outcome occurs in 6% and 12% of women and men over 80 years of age hospitalized for severe COVID, respectively. Factors associated with a higher risk of death in patients with SARS-CoV-2 include age and low circulating lymphocyte counts. Significant lymphopenia is indeed frequently observed in patients with severe COVID-19 and both phenotypic and functional changes in antiviral T cells have been correlated with the severity of COVID-19. The thymus, the organ that produces T lymphocytes, undergoes progressive physiological involution with age. However, in the elderly, rare cases of thymic hyperplasia are reported in autoimmune diseases or cancers, or are observed in response to deep lymphopenia, whether or not associated with sepsis. This cohort of patients treated for a SARS-CoV-2 infection could allow to better understand the role of the thymus in this pathology.

In literature, there is no data evaluating respiratory functions in volleyball players during Covid-19 pandemic. The aim of this study is to evaluate and compared pulmonary functions, respiratory muscle strength, body compositions and performance situations perceptions in female volleyball players with Covid-19 and non-Covid-19.

While the coronavirus pandemic has spread rapidly around the world, it has generated a considerable degree of fear, concern and anxiety among the population in general and among certain groups in particular, such as older persons. Initial findings from studies in China indicated the presence of moderate to severe psychological impact in a significant proportion of individuals and an increased prevalence of post-traumatic stress symptoms. It should also be noted that other types of symptoms, such as anxiety and depression, appeared to persist over time and to a greater extent. Osteoarthritis can develop in any joint, but most often affects the knees, hands and hips. People with osteoarthritis are often older and sometimes more frail than the general population. The main recommendations for non-drug treatment of osteoarthritis include education, physical activity and structured exercise programmes with or without weight reduction. Due to the confinement associated with COVID-19, many patients have had to stop exercise/physical activity and postpone prosthetic surgery. Apart from the context of delay in surgery, there is little data available on the impact of the pandemic on people with arthritis. Several questions are therefore still pending concerning the impact of the pandemic on these patients. The investigators hypothesise that the following therapeutic modalities have been disrupted during this period: access to care, scheduling of prosthetic surgery, consumption of painkillers or NSAIDs, recourse to physical activities, recourse to physiotherapy sessions, weight changes, level of pain.... Our objective is to evaluate the physical, social, psychological and behavioural consequences of the COVID-19 pandemic in a cohort of osteoarthritis patients.

Since the outbreak of coronavirus disease 2019 (COVID-19), more than 100,000 patients have died in the United Kingdom. Acute kidney injury is common in critically ill patients with COVID-19. It is associated with a high risk of dying. At present, it is not clear how to prevent or treat kidney failure in these patients. Recent research has shown that the coronavirus can directly infect kidney issue. It uses a particular protein on the cell surface (the ACE2 receptor) for entry into cells. Entry into cells is easier if the blood is more acidic. The aim of this project is to find out whether urinary alkalisation using intravenous bicarbonate is feasible and can reduce the risk of acute kidney injury in critically ill patients with COVID-19.

COVID-19 has been a challenge for hospitals; there was an obvious need to reconvert many spaces in specific areas to attend this pathology, without forgetting the attention to other pathologies and surgery. The objective of the investigators is to evaluate the impact of this pandemic in the patients who underwent surgery in Bellvitge University Hospital, analyzing 2 periods of time: the months before the COVID-19 peak and the COVID-19 peak months.

The medical charts of all COVID-19 cases (n=1200) from 17 long-term care facilities in Montreal, Canada will be reviewed, to compare patients who survived to patients who did not survive. Through multilevel logistic regression, the risk of death will be estimated for institutional predictors of mortality, while controlling for individual risk factors. Individual covariates include clinical features (age, sex, Charlston comorbidity index, SMAF autonomy score, severity criteria) and medical treatments (IV fluids, anticoagulation, oxygen, regular opiates, corticosteroids). Aggregate covariates include epidemiological data (attack rates, timing of outbreak) and institutional characteristics (number of beds, air exchange per hour, presence of a dedicated COVID-19 unit at the time of outbreak, staff compliance to infection control measures, staff infection rates, understaffing, proportion of semi-private rooms, proportion of wandering wards and other special units).

Covid-19 vaccines offered a good opportunity to counteract the spread of Sars-Cov-2 infection among the general population, reducing significantly both morbidity and mortality. Nevertheless, after the first and second doses of vaccination (regardless of the type of vaccine used) several women required gynaecological visits claiming menstrual Irregularities or abnormal uterine bleeding. Considering this anecdotal evidence, a questionnaire was designed to investigate systematically whether menstrual Irregularities or abnormal uterine bleeding occurred in a significant percentage of women undergoing first and second doses of covid-19 vaccination.

The main objective of the study is to assess the level of vaccination coverage (VC) against COVID-19 among migrants, homeless and travelling community, according to their living conditions and housing. The secondary objectives are : to compare the estimated level of vaccination coverage in the different sites and strata (emergency shelters/hotels, camps, workers' hostels, on the street) with the estimated level in the general population of the same territory obtained from the French Health Insurance data (SIVAC). identify the obstacles and leverage of vaccination (i.e. mobile team) according to living conditions and habitat (socio-demographic factors, personal health history, vaccine adherence, local health policies, etc.).
