Active clinical trials for "COVID-19"

Flow controlled ventilation (FCV) is a fairly new mode of mechanical ventilation, consisting of a constant inspiratory and expiratory flow. Inspiration is thus comparable to volume controlled ventilation (VCV). The actively controlled, constant flow during expiration is unique. FCV is known to minimize dissipated energy to the lung [ref] and is therefore supposed to aid in lung protective ventilation. The VICAR study is designed as a prospective single cohort crossover trial. The intervention consists of a sequence of respiratory modes: baseline pressure controlled ventilation (PCV) during 5 minutes, followed by 30 minutes of FCV with an evone respirator (Ventinova Medical B.V., Eindhoven, The Netherlands) and eventually 30 minutes of VCV. Every participant will receive the intervention. Respiratory rate (RR), positive end-expiratory pressure (PEEP) and inspiratory fraction of oxygen (FiO2) will be held constant. According to the manufacturers guidelines, an I:E ratio of 1:1 will be pursued during FCV. During FCV, the respirator will be set with the same PIP as during baseline PCV. For VCV, the same tidal volume as during baseline PCV will be set.

COVID-19 pandemic affected the admission of patients to the hospital especially the older patients (> 65 years old) because of curfews and the reluctance of patients to apply to the hospitals. Chronic kidney disease is characterized with the progressive loss of kidney function over the time and regular follow-up of patients for their kidney function and treatment of complications is recommended in these patients.

This study was carried out to determine the fear of Covid-19 and the compliance with protective measures of students who continue their education face-to-face during the covid-19 pandemic process.

The aim of this study is to explore the relation between indicators of central sensitisation, quality of life and functional status in patients post covid-19 infection.

To find out what adaptations have been made by Inflammatory bowel disease physicians and patients in relation to therapies in flaring IBD patients during severe acute respiratory syndrome 2-COV and what the impact of these is on IBD patients with no symptomatic COVID-19 and in suspected/confirmed COVID-19. Also whether there any IBD related factors impacting the outcome of patients with COVID-19 symptoms or COVID-19 disease

The purpose of this study is to assess the health and wellbeing of pregnant and recently pregnant women during the COVID-19 pandemic using an online survey.

In the context of the COVID19 pandemic and containment, chest CT is currently frequently performed on admission, looking for suggestive signs and basic abnormalities of COVID19 compatible viral pneumonitis pending confirmation of identification of viral RNA by reverse-transcription polymerase chain reaction(PCR), with a reported sensitivity of 56-88% in the first few days, slightly higher than PCR (60%) (1). Nevertheless, currently established radiological abnormalities are not specific for COVID19 and the specificity of the chest CT is ~25% when PCR is used as a reference (1). Deconfinement and its consequences will complicate the triage of COVID patients and the role of the scanner, with the expected impact of a decrease in the prevalence of infection in the emergency department and an increase in the number of "all-round" patients, including patients with non-COVID viral infiltrates or pneumopathies. In addition, there are currently no imaging criteria to complement the clinical and biological data that can predict the progression of lung disease from the initial data.

The FORECAST Study is an observational cohort study looking at two cohorts of patients presenting with COVID-19: a general public cohort, aiming to investigate if new loss or reduced sense of smell and/or taste are early signs of COVID-19 and a hospital cohort, which will investigate if taste/smell changes can predict the clinical course of a COVID-19 infection.

Background After the emergence of Covid-19 in China, Hubei Province, the epidemic quickly spread to Europe. France was quickly hit and the Croix-Rousse hospital at the Hospices Civils de Lyon was one of the first French university hospital to receive patients infected with Sars-COV2. The predicted massive influx of patients motivated the cancellation of all elective surgical procedures planned to free hospitalization beds and to free intensive care beds. Nevertheless, patients who had to be canceled had to be properly selected to avoid a life threatening. The retained surgical indications were surgical emergencies, oncologic surgery and organ transplantation. The objective was to describe the organization of the Croix-Rousse hospital to allow the continuation of these surgical activities while limiting the exposure of patients to the Sars Cov2.

It is unclear how COVID19 can be passed from mother to infant. The study investigators aim to collect maternal and neonatal samples from COVID19-infected pregnant women and compare them to pregnant women who have clinical indications for COVID 19 testing at the time of hospital admission but end up being COVID19 negative. Pregnant women who are either COVID19 positive or COVID19 negative with respiratory symptoms will be enrolled and followed during this study.
