Active clinical trials for "COVID-19"

Patients with coronavirus disease (COVID-19) and pneumonitis often have hypoxemic respiratory failure and a need of supplementary oxygen. Guidelines recommend controlled oxygen, for most patients with a recommended interval of SpO2 between 92 and 96 %. We aimed to determine if closed-loop control of oxygen was feasible in patients with COVID-19 and could maintain SpO2 in the specified interval.

The study aims to examine whether a nationwide lock-down with an entire population subjugated to social distancing reduces the incidence of appendicitis. If a reduction is detected it supports the hypothesis that infectious disease may play a role in the etiology of appendicitis.

A study to assess the impact of coronavirus disease 2019 (COVID-19) pandemic on the attitude, behaviour and mental health of rheumatic patients and to compare them with healthy individuals.

In this prospective observational study we aim to study the association of vitamin D deficiency with adverse clinical outcomes in patients infected with Coronavirus disease 2019

The purpose of the questionnaire is to find risk factors for the development of post-traumatic stress disease (PTSD) in health workers during COVID-19 pandemy.

The study is devoted to the comparative analysis of the data received in patients with COVID-19 lung pathology using the method of probe-based confocal laser endomicroscopy of distal airways and two reference methods: high resolution computed tomography and morphology (in some patients).

Severe SARS-CoV-2 infection, responsible of COVID-19, is accompanied by many venous thromboembolic events. Antithrombotic treatment is the cornerstone of management of many neurovascular diseases (NVDs) and the benefit-risk ratio is crucial to avoid hemorrhagic complications. Therefore, in non-severe COVID-19 patients affected by NVDs, the diagnostic of deep venous thrombosis (DVT) is challenging. Using bedside Doppler ultrasonography (DUS) of lower limbs, this study investigated the rates of DVT in these patients in stroke unit.

The study is a cross-sectional survey study targeting patients aged 45-75 who had their screening or surveillance colonoscopy postponed or delayed due to the COVID pandemic. Study staff will survey a random subsample of patients to assess anxiety, COVID risk tolerance, cancer worry, willingness to screen and barriers to screening colonoscopy, and preference for colonoscopy and alternative colon cancer screening options. Eligible patients will be sent a survey packet in the mail that will include a cover letter, an information sheet describing the study, an incentive, and the survey. The cover letter will include information for participants to opt-out if they desire. Patients will be asked to complete the survey and return it back to study staff. Consent is implied with return of the survey. For the study, staff plan to invite 300 patients and expect to receive 195 completed surveys. Analyses will examine whether COVID-19 has changed patients' interest in colon cancer screening and the strength of patients' preferences for colonoscopy and other approaches to colon cancer screening. It will then examine factors associated with positive and negative views on rescheduling colonoscopies such as anxiety, worry, and risk perceptions.

The aim of this study is to analyze the perceptions, representations and experiences of septic isolation of patients hospitalized for COVID-19 infection. This analysis could lead to better understanding and communication between the medical profession and patients in septic isolation in hospital. It would also provide patient-specific responses to their expectations, as to their families.

A retrospective cohort study investigating clinical notes using Natural Language Processing in combination with structured data from the Electronic Health Record (EHR) to create a database for analytics to identify features associated with outcomes.
