Filter by:This study will evaluate the associations between vascular parameters and clinical outcomes in patients hospitalized with COVID-19. The vascular function and structure of individuals with COVID-19 admitted to the General Hospital of the University of Sao Paulo will be assessed in the first 72 hours of hospitalization. Then, participants will be followed up until hospital discharge/death. Logistical regressions will be run to evaluate if vascular function/structure can predict ICU admissions, intubation, thrombosis or death.
The purpose of this research is to understand if the study drug, also called sargramostim or Leukine®, can help prevent the worsening of COVID-19 when the study drug is inhaled. This study will also help researchers understand if inhaled sargramostim can help prevent visits to the emergency room or hospitalization, or death.
To better understand the role of inflammation in COVID-19, we established the Michigan Medicine COVID-19 Cohort (M2C2). M2C2 is a funded and ongoing cohort which has currently enrolled over 1500 adult patients (≥18 years) with severe COVID-19 admitted at the University of Michigan. The purpose of M2C2 is to define the in-hospital course of these patients and understand the role of inflammation as a determinant of organ injury and outcomes in COVID-19.
There is an unmet need to evaluate the impact of sub-clinical/mild COVID19 disease in the outpatient setting on prevalent and incident renal injury, as this data is currently unavailable. To capture the diversity of race/ethnic risk and COVID19 related municipal shelter-in-place guidance, the investigators will enroll COVID19-negative and COVID19-positive samples balanced by race/ethnicity from 3 different states, California, Michigan, and Illinois. Study endpoints will be assayed from urine samples mailed to the study team at 2, 6, and 12 months after their date of PCR test, with no requirement for these individuals to leave their homes to participate.
COVID-19, the coronavirus responsible for the pandemic that began at the end of 2019 in China, spreads through respiratory droplets and direct contact. The most common symptoms of the disease include fever, cough, asthenia or myalgia, wheezing and headache, and the most serious complication is acute respiratory distress syndrome (ARDS). The new coronavirus has continued to spread to multiple countries and continents so much so that the epidemic was declared a Public Health Emergency of International Interest (PHEIC) by the World Health Organization (WHO) on January 30, 2020. In the first phase of emergency worldwide, characterized by high morbidity and mortality, scientific interest has been mainly directed to the study of the transmission mechanisms of the infection, diagnostic tools and therapies for ARDS, especially in elderly and co-morbid patients. Interest has rapidly spread to other categories of patients and in particular to pregnancy, on which the virus could impact in different ways, with consequences for both the mother and the fetus. A recent systematic review that included all published reports on Coronaviruses (COVID-19, SARS, and MERS) in pregnancy showed that preterm delivery is the most frequently reported adverse event in these women, and that COVID-19 is associated with an increased risk of preeclampsia and caesarean section. Nonetheless, the limited sample size, the main inclusion of cases reported for acute respiratory symptoms, the lack of information on previous pathologies potentially capable of complicating pregnancy, do not allow for the extrapolation of strong evidence on the course of infection in pregnancy. Therefore, the current status of the scientific literature does not allow for general and wide-ranging implications. THe investigators therefore believe it is particularly useful to investigate maternal and fetal outcomes in this new broader scenario, including all pregnancies associated with asymptomatic or symptomatic SARS-CoV-2 infection, found in any gestational period, in order to evaluate in a "real world scenario" "Actual rates of maternal-fetal and neonatal adverse events
This is a cohort study, in which the investigators will follow-up 650 health care workers (HCW) and a selection of their households (of COVID positive and COVID negative HCW) at baseline and in three follow-up surveys, with 4 to 6 weeks of time interval. The investigators will select HCW from different wards and different health care structures in 5 communes of Kinshasa. Additionally, in the first survey among HCW, the investigators will test with different diagnostic platform to evaluate the performance of serological tests in the African setting and the effect of malaria infection on the performance of tests. An amendment is added to the protocol, stating an additional 2 surveys in april/June 2021 and October/November 2021 to evaluate impact of second wave and of vaccination campaign.
Multicenter, randomized, blind, placebo-controlled clinical study of III phases on the assessment of preventive efficiency, safety and immunogenicity QazCovid-in®-vaccine against COVID-19 in healthy adult volunteers
The pandemic caused by SARS-CoV-2 is a global emergency present in 6 continents including 66 countries, incurring a shortage of effective and safe therapeutic alternatives that can contribute to reducing the risk of contamination, as well as helping to reduce the viral load of the positive patient. This requires a coordinated, effective and immediate action on the part of governments, companies, academic entities and even at the individual level. In the search for new therapeutic and prevention alternatives, the application of hypochlorous acid (HClO) to the nasal mucosa is proposed, a broad-spectrum and fast-acting antimicrobial solution, whose safety has been proven in preclinical trials. The efficacy of HClO has been tested against enveloped and non-enveloped viruses, reducing virus particles without affecting human cells. This solution could contribute to reducing the viral load and the risk of contamination of patients and professionals. This could have an impact on controlling the COVID-19 pandemic.
The investigators hypothesize that sex, age, area of exposure and purpose of travel are associated with different travel-related infections. The investigators also hypothesize that certain infections will have long-term sequelae. Health-data will be collected from travellers from Switzerland and Europe. The project starts with a pilot study for 50 travellers, followed by the recruiting of 10,000 travellers. The data collection will be via a mobile App (ITIT). The ITIT App will collect active data from travellers. The participants will download the App after signing an electronic consent form and completing a baseline questionnaire. Then the travellers will answer a short daily questionnaire about illness symptoms during travel. The ITIT App will also collect passive data (GPS localisation, environmental and weather data). The project will provide real-time data on travel-related infections and profile travel illness by age, sex and purpose of travel and also identify outbreaks.
This is a Phase 2, randomized, placebo-controlled, and observer-blind study in healthy adults. The study will evaluate the safety, tolerability, and immunogenicity of the SARS-CoV-2 RNA vaccine candidate against COVID-19: As 2 doses (at two different dose levels), separated by 28 days or as 1 dose In adults 18 years of age and older
