Active clinical trials for "COVID-19"

In this study the investigators record sounds of voice, breaths and cough of subjects who tested positive for COVID19. The investigators then feed these sounds into an artificial intelligence and see if it can learn to recognise features to make COVID19 diagnosis from these sounds in order to avoid to use swabs to test the general population.

A huge number of initiatives about COVID-19 are ongoing and a growing number of publications regard the correlation between cancer patients in general and SARS-CoV-2 infection. Although it has been reported that cancer patients are at a higher risk of SARS-CoV-2 infection and COVID-19 complications, data collection about cases of NEN patients SARS-CoV-2 positive are scattered and related to single countries or institutions. Because of that and due to the rarity and heterogeneity of NEN it will be hard to have homogeneous, reliable, representative and reproducible data for drawing adequate clinical recommendations about NEN patients and COVID-19. Therefore we propose a global collection of data through an international database to describe and monitor NEN patients with SARS-CoV-2 infection. This retrospective/prospective collection of data can create a solid basis to check frequence of events, clinical management, clinical outcome, demographic, geographical, clinical and biological correlations. This will be helpful for the clinical and scientific community to get reliable information for a homogeneous clinical management of NEN patients during COVID-19 pandemic. The main goal is to get the as wide as possible representativity of the world situation.

The aim of this study is to apply serology testing methods for SARS-CoV2 antibodies in samples collected from HCWs in an acute hospital. This will enable the identification of those who are protected and non-infectious for SARS-CoV2 and those who are seronegative and therefore potentially susceptible and infectious on patient contact. Prospective testing will provide data on the acquisition of SARS-CoV2 infections among HCWs and associated risk factors for transmission during a pandemic at an acute care hospital facility in the capital region of Denmark. Hypothesis: Serial seroconversion measurements in hospital employees improve the organization of the clinical treatment and care during the COVID-19 pandemic at Nordsjællands Hospital and Nykøbing Falster County Hospital.

The unexpected onset of SARS-COV2 infection modified our practices, especially in routine medicine. In order to reverse the epidemic curve of severe cases and slow the spread of the infection, confinement was generalized in France from March 13, 2020.These restrictive measures were imposed on anyone with symptoms compatible with the infection, with the exception of dyspnea and other criteria of severity. March 12, 2020 is the pivotal date when the management of COVID came to interfere with medical and healthcare organizations. From this date, it is likely that some imaging or endoscopic exams have been de-scheduled for symptoms that are sometimes wrongly judged to be non-urgent and have seen their numbers drop dramatically.Otherwise, concerning lung cancer, preventive measures have been extremely strengthened. For instance, it is recommended to delay surgeries for localized tumors, to relieve or remove some chemotherapy or to delete radiotherapy sessions deemed non-essential. However, symptoms that may initially be attributed to viral infection, such as cough, fever, fatigue, or chest pain may be clinical indicators of early-stage Lung cancer. In addition, lung cancer is likely to make the patient more susceptible to pneumopathy, due to a weakened of immune response to viruses and bacteria. Consequently, as necessary as the restriction measures are, a risk of slowing down in the management of the Lung cancer pathology exists. The CBP-COVID Study intends to assess consequences of restrictive measures linked to the SARS-COV2 epidemic, by comparing clinical characteristics at diagnosis, treatment times and treatments, regarding to 2 distinct time periods identical to the calendar, but one in 2019, the other in 2020.

This is a retrospective/prospective, cohort, non-interventional observational study. This means that all patients with documented COVID and HM diagnosed between February 2020 and study initiation will compose the retrospective part, while those diagnosed after study approval will enter prospective part. The total duration of the study will be 12 months. The study population will must be older than 18 years of age with HM and SARS-CoV-2 infection. All patients with documented SARS-CoV-2 infection (COVID) and history or active hematological malignancies, who refer to any Hematological Unit will be included.

This is an observational study of patients with COVID-19 designed to specifically address important clinical questions that remain incompletely answered for coronavirus disease 2019.

COVID-19 may cause another world-wide epidemic. This study is divided into 2 arms: (1) Prospective longitudinal observational study involving patients with laboratory-confirmed COVID-19 and (2) Retrospective study on patients with laboratory-confirmed COVID-19. Arm 1: We will collect EDTA blood, stool samples, rectal swab, urine, saliva, and specimens from upper respiratory tract (nasopharyngeal aspirate or flocked swab), and lower respiratory tract (sputum or tracheal aspirate) on daily, alternate day, or weekly basis as appropriate. Arm 2: The remainder of specimens that were submitted for laboratory investigation as part of clinical management will be retrieved. Those specimens will only be used after all clinically indicated testing and confirmation procedures have been completed. Assistance from the Public Health Laboratory Service, Department of Health, will be invited to retrieve samples as well as participate in this study. Patients hospitalized for pneumonia in medical wards and ICU at the Prince of Wales Hospital tested negative for COVID-19 will be recruited as controls. Understanding the clinical, virological, microbiological and immunological profiles of this infection is urgently needed to facilitate its management and control.

Some authors have proposed the use of the flu vaccine to reduce the severity of COVID-19 cases, while some have proposed the use of ACE Inhibitors (ACEI) or Angiotensin Receptor blockers (ARB), since this virus shares hemagglutinin as a transmission mechanism and acts on the ACE2 enzyme during infection. Other authors described how none of the elderly patients receiving antihistamines and azythromycin in two nursing homes in Toledo -Spain- during the first wave died or needed hospital admission, even considering that 100% of residents had a positive serological test after that wave. Other authors have described a positive evolution in patients receiving amantadine for their Parkinson's disease. The aim is to evaluate whether the admitted patients who are previously vaccinated or those who were already receiving these treatments showed a better evolution.

This study seeks to determine whether the virus which causes COVID-19, SARS-CoV-2, is shed in the stools of patients who are infected.

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.
