Filter by:Hypoxemic acute respiratory failure is one of the main COVID-19 patients complication that lead to in intensive care hospitalization. This complication determines a variable mortality from 25 to 30%. To correct hypoxemia (often severe) is often needed non-invasive or invasive mechanical ventilation. Mechanical ventilation is not a therapeutic strategy, but it allows to extend the time-to-recovery necessary to solve COVID-19 respiratory failure cause. Calibration of ventilatory support is essential to ensure adequate time-to-recovery without contributing to onset lung and / or diaphragmatic damage. Basal diaphragmatic activity assessment, device for administering the oxygenation support choice and setting ventilatory support parameters are decisive. Ultrasound is the best method for measuring diaphragmatic work. The aim of this study is to evaluate the diaphragmatic thickening fraction in COVID-19 patients admitted to Intensive Care Unit (ICU) for acute respiratory failure and to record its function on weaning.
Coronavirus disease 2019 (COVID-19) is a serious respiratory disease that results from infection with a newly discovered coronavirus (SARS-COV-2). Unfortunately, COVID-19 is not only a short-term infection. Patients (pts) recovering from SARS-COV2 infection complain of persisting symptoms including: fatigue, diffuse myalgia and weakness, which may lead to chronic fatigue syndrome and as well as many other complications. The vast majority of COVID-19 patients remaining in isolation/quarantine, due to the mild course of the disease, do not require hospitalization. In this group of patients, the course of COVID-19 is very different - from asymptomatic patients to very severe and long lasting symptoms also with a decrease in saturation. There are many studies describing the course and complications of patients hospitalized due to COVID-19. There is little published data on how non-hospitalized patients get sick and what are the early and late complications of SARS-CoV-2 infection. In addition, many patients remain ill even many months after COVID-19, entering what is known as LONG-COVID. Therefore, the STOP-COVID Registry was established. The purpose of the Registry is to assess the course of COVID-19 infection, early and late cardiovascular complications of COVID-19 in patients with and without hospitalization. In addition, the purpose of the STOP-COVID Registry is to assess the incidence of LONG-COVID with all other complications and to identify predictive factors.
This study will test the COVID-19 vaccine candidate AZD1222 to investigate its safety, tolerability and capability of boosting immune responses both in the blood and the lung when administered to the respiratory tract, in volunteers previously vaccinated by intramuscular COVID-19 vaccination. Using standardised methods, we will measure immune responses in the blood, nose and lower airway and compare with data from ongoing clinical trials of intramuscular vaccination. Thus, we will show the effect of the delivery method and provide the critical information required to begin further clinical trials to show the efficacy of this needle-free vaccination strategy for booster vaccination.
This will be a prospective observational study of lactating mothers who are planning to, have scheduled or have received vaccination against SARS-COV-2 (COVID-19 vaccine). Mothers may have delivered at Mount Sinai Hospital or may be from the general public recruited by social media or word of mouth. As the study participants will be lactating mothers, they will not be under the care of the investigators. Due to lack of information, we are unsure of an appropriate sample size but envision we will recruit at least 10 women each immunized with the approved mRNA vaccines (e.g. Pfizer-BioNTech and Moderna COVID-19 vaccines) and in the future at least two other vaccines (e.g. Oxford-AstraZeneca) as they are approved and become available. Milk samples will be analyzed for the presence of antibody to SARS-CoV-2 using the Anti-SARS-CoV-2 ELISA (IgG and IgA). These analyses will be conducted in the Department of Microbiology at Sinai Health following validation of the procedures in human milk.
Randomized, open, single-center, controlled clinical trial, with 2 treatment arms that seeks to demonstrate the effectiveness of tocilizumab against systemic corticosteroids, both treatments added to supportive treatment in patients admitted for COVID-19 with bilateral pneumonia and poor evolution
This is an observer-blind, randomized study which aims to assess the immune response and the safety of two different approved vaccines for first and second dose in healthy adults.
To measure the frequency of persistent liver dysfunction (raised liver enzymes, serum albumin, prothrombin time, etc) in recovered COVID -19 patients. To compare the hepatic manifestations in post COVID -19 patients with and without liver disease
EC CORONACOLCHI is a multicenter, double-blind and randomized clinical trial with two branches. Patients who meet all the inclusion criteria and none of the exclusion criteria will be randomized 1: 1 to be included in one of the following groups: - Experimental group: colchicine for 2 weeks orally at the doses described, added to the standard treatment of COVID-19. - Control group: placebo for 2 weeks orally added to standard COVID-19 treatment.
Coronavirus disease 2019 (COVID-19) which is caused by the virus SARS-CoV-2 has resulted in an ongoing global pandemic. It is unclear whether the relatively low number of reported cases of COVID-19 in people with CF (pwCF) is due to enhanced infection prevention practices or whether pwCF have protective genetic/immune factors. This study aims to prospectively assess the proportion of pwCF, including both adults and children with CF who have evidence of SARS-CoV-2 antibodies over a two-year period. This study will also examine whether pwCF who have antibodies for SARS-CoV-2 have a different clinical presentation and what impact this has on their CF disease. The proposed study will recruit pwCF from paediatric and adult CF centres in Europe. Serological testing to detect antibodies will be performed on blood samples taken at month 0, 6, 12, 18 and 24 with additional time-points if bloodwork is available via normal clinical care. Clinical data on, lung function, CF-related medical history, pulmonary exacerbations, antibiotic use, and microbiology and vaccination receipt, will be collected during routine clinical assessments. Associations will be examined between socio-demographic and clinical variables and serologic testing. We will also examine the effects of SARS-CoV-2 infection on clinical outcomes and analyse end-points to explore any age-related or gender-based differences, as well as subgroup analysis of outcomes in lung-transplant recipients and pwCF receiving CFTR modulator therapies. As pwCF receive COVID-19 vaccination we will perform a comparison of the development and progression of anti-SARS-CoV-2 antibodies in pwCF following natural infection and vaccination SARS-CoV-2 over time.
Preliminary data suggest that inactivated vaccine-induced neutralizing antibodies against SARS-CoV-2 decrease at six months after vaccination. Observational, unpublished data also indicate that vaccine effectiveness against Covid-19 wanes over time. Thus, the investigators aimed to determine the reactogenicity, safety, and immunogenicity of a homologous or heterologous booster of SARS-CoV-2 vaccines among people already immunized with an inactivated SARS-CoV-2 vaccine. The study focuses on the elderly population and healthcare workers.
