Active clinical trials for "COVID-19"

Chest computed tomography of patients having coronavirus disease (COVID-19) will be analyzed with regards to vascular abnormalities (pulmonary embolism and vascular thickening), and their association with lung inflammation. The prevalence, severity, distribution, and prognostic value of chest CT findings will be assessed. Patients with vascular abnormalities will be compared to patients without, which is supposed to provide insights into the prognostic role of such abnormalities, and the potential impact on treatment strategy.

The COVID-19 outbreak in our environment has caused significant changes in the population. The main objective of this research project is to evaluate the level of physical activity, psychological state and sleep during the COVID-19 pandemic in different populations.

This study aims to address the following three objectives: Longitudinal evaluation of the development of CMI responses in response to SARS-CoV-2 Vaccine: T cells isolated from the blood of COVID-19 vaccine recipients will be evaluated for their functionality in response to vaccine antigens. The temporal and functional properties of CMI responses will be correlated with the humoral or antibody responsiveness. CMI responses will be measured in vaccine recipients prior to vaccination to determine whether the presence or functionality of pre-existing responses to common cold coronaviruses (CCCs) or previous SARS-CoV-2 infections affect the development of CMI responses to the COVID-19 vaccine. Identification of cellular and soluble factors that influence vaccine responsiveness: While it is known that poor clinical outcomes in COVID-19 patients are strongly associated with markers of systemic inflammation, the influence these systemic markers will have on COVID-19 vaccine responsiveness is not clear. Using systems biology approaches, the investigators will perform comprehensive profiling of cellular immune subsets, inflammatory signatures to identify determinants influencing the development of CMI responses to vaccine. Examine variability of immune and viral genes and their relationship to vaccine induced immune responses: Human leukocyte antigen (HLA), T cell receptor (TCR) and B cell receptor (BCR) proteins are highly genetically diverse and critical to development of protective immunity. The investigators will perform HLA sequencing on whole blood-derived DNA samples and TCR and BCR sequencing on sorted, SARS-CoV2 vaccine antigen-specific T cells and B cells, respectively, to assess how different sequence combinations impact the CMI responses to vaccine.

Application of a survey in electronic support to hospital professionals. This survey will include different demographics as well as questions from own elaboration about the different aspects related to the development of work during the health emergency. A third part will be included different validated scales for screening / diagnosis of different problems that can present those who are working in the Current situation. The different scales are the PHQ-9, GAD 7, ISI, and EIE-R. These scales address the different problems that have been seen that can introduce professionals, Depression, Anxiety, Insomnia and adaptation to stressors.

In this observational study follow-up and dynamic observation will be conducted on the participants recovered from pneumonia caused by COVID-19. The main goal is an early diagnosis and detection of myocardial (heart) injury and quality of life in participants recovered from COVID-19 and follow-up in selected participants with present signs of myocarditis and/or myocardial fibrosis.

Coronavirus disease 2019 (COVID-19) infection caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may manifest as a variety of disease patterns, ranging from mild to life-threatening pneumonia. Mucormycosis has been suspected to cause significant morbidity in infected people since the outbreak of the COVID-19 pandemic. Individuals who require hospitalization and intensive care are more vulnerable, as they have reached an advanced stage of their disease. Investigators will discuss the major risk factors, ocular presentation, and outcome of mucormycosis in individuals infected with SARS-CoV-2 in this study. From August 2021 to January 2022, a cross-sectional descriptive multicenter investigation would be conducted on patients with biopsy-confirmed mucormycosis and RTPCR confirmed COVID19. Demographic data, the time interval between COVID19 and mucormycosis, underlying systemic disorders, clinical characteristics, disease course, and outcomes would be analyzed.

This study aims at determining clinical presentations and outcomes of patients with covid-19 pneumonia and also follow up of patients for up to 6 months to detect possibility of post covid fibrosis

The diagnostic performance of the scanner in the indication of suspected Covid-19 is not yet well known, especially in comparison with the results of RT-PCR. The potential use of the scanner as a tool for quantifying the severity of Covid-19 disease is not yet well established, especially the variations between readers or between measurement techniques. The impact of the scanner in predicting the fate of patients with confirmed Covid-19 is not yet known.

The TRANSCOV cohort is a multicentre observational retrospective study aiming at assessing the health impact of extra regional transfers of critically ill COVID-19 patients.

This study aims at assessing esophageal pressure in patients with acute respiratory failure due to COVID-19 undergoing non invasive respiratory support.
