Active clinical trials for "COVID-19"

Since the beginning of 2020, a major pandemic due to the new emerging coronavirus (SARS-CoV-2) has been spreading around the world. Today, the hope to contain this pandemic lies in the development and use of vaccines directed against this virus. Different strategies aim to maximize the early impact of vaccination in a context where few doses are available. In early January 2021, large-scale vaccination began in France, first for populations at risk of severe COVID-19, but also for healthcare workers over 50 years of age or with an underlying pathology, and then for all voluntary healthcare workers.

Comparing the incidence of complicated appendicitis between two groups, the pandemic and pre-pandemic groups.

Guidelines for endourological procedures during COVID-19 have suggested deferring all elective procedures, while obstructed/ infected stones should undergo urgent decompression. At our centre, screening protocols were implemented with prioritization strategies so that elective care could safely continue at deescalated rates. COVID or septic patients underwent emergency decompression, while non-COVID and non-septic patients underwent primary ureteroscopy (URS) or retrograde intrarenal surgery (RIRS). We aim to report our experience with endourological surgery for stone disease during COVID-19.

The AudibleHealth Dx is a diagnostic software as a medical device (Dx SaMD) consisting of an ensemble of software subroutines that interacts with a proprietary database of Signal Data Signatures (SDS), using Artificial Intelligence/Machine Learning (AI/ML) to analyze forced cough vocalization signal data signatures (FCV-SDS) for diagnostic purposes. This study will evaluate the performance of the AudibleHealth Dx in comparison to a standard of care Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) test for the diagnosis of COVID-19. Bidirectional Sanger sequencing will be used to reduce the rate of false negative and false positive results. A secondary purpose of the study will be usability testing of the device for participants and providers.

Background: Asthma is still considered a major chronic respiratory disease that affects a large number in the world. The association between COVID-19 infection and asthma was studied in different ways focusing on hospital admitted patients. This study aimed to evaluate the relation between asthma and COVID-19 infection in adults attending outpatient pulmonary clinic over three successive months from clinical and laboratory point of view. Patients and methods: The current study collected 1309 patients attending the outpatient pulmonary clinic of a Saudi Arabian private Hospital over three successive months from 1st of December 2020 to the end of February 2021. Patients were divided into three groups; Group 1: COVID-19 infected with asthma (312), Group 2: COVID-19 infected with no asthma (286) and Group 3: COVID-19 non-infected with asthma (300).

Depersonalized multi-centered registry initiated to analyze dynamics of non-infectious diseases after SARS-CoV-2 infection in population of Eurasian adult patients.

Since the beginning of COVID-19 pandemic situation, several modes of ventilation have been tried to correct the hypoxaemia induced by SARS-CoV-2 virus. A few recent studies have concluded that high-flow nasal oxygen therapy (OptiFlow™) is beneficial in COVID-19. All mainly conclude that the use of OptiFlow™ avoid intubations and decrease hospitalization duration in critical care services. At the emergency medical service 83 (SAMU 83), it has been decided to extend this ventilation mode during patient secondary transfers (transfer from an intensive care unit/other hospital unit/emergency department to another hospital's intensive care unit). The emergency medical service 83 has equipped its intensive-care ambulances with OptiFlow™ in order not to interrupt this ventilation mode during transport. The hypothesis is that patients with a severe respiratory form of COVID-19 transported from one health facility to another by the emergency medical service 83 on high-flow nasal oxygen therapy has a reduced risk of intubation compared to the other modes of non-invasive ventilation (NIV) and High Concentration oxygen Masks (HCM).

SARS-CoV-2 transmission is dependent on multiple factors, which may be related to either host-virus interaction or the environment. While there have been several studies evaluation viral dynamics and transmission risk in adults, there is limited pediatric data available. The objective of this study is to characterize the period of communicability for children less than 19 years of age with SARS-CoV-2 infection with the Omicron variant.

Investigation of the cardiac manifestations of COVID-19 in patients admitted to hospital

Patients with chronic kidney disease (CKD), particularly those undergoing hemodialysis (HD), are at high risk of a severe form of COVID-19. This study aims to characterize the inflammatory and antiviral response during SarsCov2 infection in adult
