Active clinical trials for "COVID-19"

It has been well documented that coronavirus COVID-19 disease is associated with massive inflammatory response and cytokine storm. Several medications have been used to ameliorate COVID-19-related inflammation. Xanthohumol, a natural medication extracted from hop cones, possesses strong anti-inflammatory properties and can reduce the severity of inflammatory response. The aim of this study is to analyze the effect of Xanthohumol on clinical course, inflammatory response and outcome in patients admitted to the ICU due to COVID-related acute respiratory failure with an oxygenation index (PaO2/FiO2) less than 150.

This is an exploratory phase 3, cohort randomized, observer-blind, multi-center study to evaluate the safety and immunogenicity of a 4th dose of various SARS-CoV-2 vaccines. There will be 04 study cohorts, that have previously received 03 doses of the indicated vaccine (s), divided into 10 groups; and each one of the 10 study groups will receive the 4th dose. This exploratory study will enroll up to 360 participants in 4 cohorts and a total of 10 groups: Cohort A (N=90), Cohort B (N= 90), Cohort C (N=150) and Cohort D (N=30). In cohorts A-C participants will be randomized 1:1:1 to three different 4th dose regimens. The number of proposed participants will provide a reasonable accurate descriptive summary of the safety and immunogenicity of the tested vaccination regimens.

Covid is a virus that first appeared in China in 2019 and was quickly described as a pandemic virus by its globalized nature. The unprecedented occurrence of the virus has led to several health and restrictive government measures. The Covid-19 pandemic and health measures have been able to contribute to the deterioration of the mental health of citizens as it has already been observed during the former pandemic context (Sars covid in 2003 in China or the Spanish flu). Among the consequences of a negative impact on mental health, investigators assume that there is an increase in transitions to the completed suicidal act. However, current studies and observations tend to note that there has been no major change in the dynamics of successful suicides during the Covid period. However, there are biases in the studies conducted: some suicide deaths may have been hidden and not reported as such, due to several factors. For example, the measure of the evolution of suicide attempts that was most often made by the measure of the evolution of the number of hospitalizations for this reason can be a source ofestimate whether people who did this gesture were not hospitalized after a visit to the emergency room or if they gave up attending because of the pandemic. Moreover, suicide deaths are more difficult to report as such when they occur at home than after hospitalization. It is therefore interesting to study the dynamics of suicide during this health crisis retrospectively based on data from the Strasbourg Institute of Forensic Medicine containing the census of the Alsace region, which was hit hard by the pandemic.

Retrospective cohort study that will include patients from the ICU of the Hospital de la Santa Creu i Sant Pau in Barcelona during the period between March 11 and May 13, 2020. The cohorts are made up of two groups of patients admitted for severe COVID during the first wave, according to whether or not they received physiotherapy and the possible impact of physiotherapy on the days of mechanical ventilation in the two study groups will be studied.

The present study aims to evaluate how commonly diagnostic tools employed in the preoperative evaluation of respiratory function in thoracic surgery can identify pathological alteration due to a previous SARS-CoV-2 infection. In particular, the investigators will gather information concerning imaging (lung ct and lung ultrasound), arterial blood gas analysis, and pulmonary function tests.

This multi-center, retrospective cohort study aimed to determine which factors are associated with ongoing pregnancy rates in infertile patients received ART treatments during the current outbreak of COVID-19 infection.Couples who underwent IVF-ET/ICSI-ET/FET due to infertility in the department of Reproductive Medicine from 2022-11-23 to 2023-01-07 were included. Patients who were infected with Coronavirus were observation groups; the infection status and clinical outcome were tracked. Patients who were not infected with Coronavirus were control groups.

During the most recent pandemy COVID-19, various advises concerning complications following high corticosteroid doses administration were pubblished in 2020. However, evidence is lacking about the incidence of Non-traumatic osteonecrosis of the femoral head (ONFH) in patients experiencing COVID-19. The aim of the present proposal is to obtain a quantitative estimation of ONFH cases among patients previoulsy hospitalized and treated for COVID-19 at ASST-Papa Giovanni XXIII.

The study is aimed at the clinical and laboratory characteristics of patients with completed vaccination against SARS-CoV-2 admitted to the hospital in the standard ward and intensive care unit due to the severe course of COVID-19.

In order to detect the immunosuppression status of COVID-19 patients, this study collected blood samples of COVID-19 patients on the 10th, 20th and 30th days after the onset of symptoms, and detected the proinflammatory, anti-inflammatory factors，immunosuppressive marker，immune cells in the blood samples to evaluate the immunosuppression status of COVID-19 patients.

Based on the characteristics of symptoms, differences in physical and chemical examinations and tests, and characteristics of traditional Chinese medicine (TCM) disease differentiation and syndrome differentiation, the evaluation indicators for the clinical early warning model were screened, and the "three-level early warning mechanism for COVID-19 patients at high risks, with progression to severe cases and sequelae was constructed.
