Filter by:Males develop more severe SARS-CoV-2 infection related disease outcome than females. Herein, sex hormones were repeatedly proposed to play an important role in Covid-19 pathophysiology and immunity. However, it is yet unclear whether sex hormones are associated with Covid-19 outcome in males and females. In this study, we analyzed sex hormones, cytokine and chemokine responses as well as performed a large profile analysis of 600 metabolites in critically-ill male and female Covid-19 patients in comparison to healthy controls and patients with coronary heart diseases as a prime Covid-19 comorbidity. We here show that dysregulated sex hormones, IFN-γ levels and unique metabolic signatures are associated with critical illness in Covid-19 patients. Both, male and female Covid-19 patients, present elevated estradiol levels which positively correlates with IFN-γ levels. Male Covid-19 patients additionally display severe testosterone and triglyceride deficiencies as compared to female patients and healthy controls. Our results suggest that male Covid-19 patients suffer from multiple metabolic disorders, which may lead to higher risk for fatal outcome. These findings will help to understand molecular pathways involved in Covid-19 pathophysiology.
The increased risk of transmission of COVID-19 infection causes the incidence of death in health workers to escalate. It requires further research on risk factors and intervention in health worker professionals, especially on immunity factors and nutritional status. Quality of diet and nutrition is very important to support the immune system when infected. Several probiotic strains have been shown to decrease the duration and incidence of diarrhea and respiratory infections, suggesting the Gut-Lung Axis pathway. Some probiotics also improve the balance of diversity in the composition of the gut microbiota and affect body weight in obese people. Probiotics have also been shown to improve vitamin D absorption. A combination of vitamin D and probiotics may be an alternative to reduce gut dysbiosis that will directly or indirectly reduce the risk and severity of viral infections including SARS-CoV-2.
This study was aimed to evaluate the post-infection cognitive functions of adult individuals with COVID-19. 50 individuals with COVID-19 and 50 healthy control groups were included in the study. Cognitive functions of individuals with COVID19 compared with healthy individuals.
In collaboration with involved healthcare professionals and a patient advisory committee, this study tests the feasibility of using the Opal smartphone app to daily capture self-reported physical and psychological symptoms and vital signs among 50 people who are self-isolating at home with COVID-19. A healthcare team at Montreal's MUHC will remotely monitor their condition and offer advice and teleconsultations, as needed.
This 2-arm clustered, randomized community trial will test a multilevel, COVID-19 testing and linkage to care (eg, health insurance, medical appointments, community resources, contact tracing) intervention against a nontailored, attention-control condition on uptake of COVID-19 testing with adult African American church-affiliated members at 6 months. Contact tracing approval (beliefs and participation contact tracing) and COVID19 prevention behaviors will also be examined. Findings from this study could provide a theory-based, multilevel model for delivering scalable, wide-reaching COVID-19 testing and linkage to care services, including contact tracing, by supporting African American faith leaders with culturally-appropriate, easy-to-use tools and health agency partnerships.
To study the efficacy and safety of icatibant in adult patients admitted to hospitalization units for pneumonia caused by COVID-19, without mechanical ventilation, 10±1 days after starting treatment or discharge from hospital if this occurs before 10 days.
Background: Some people have allergic reactions to COVID-19 mRNA vaccines. Researchers want to learn more about these reactions to provide guidance on who can safely receive the vaccines, including a second dose in people who had a reaction to the first. Objective: To study the safety of giving a second mRNA COVID-19 vaccine dose to people who had a systemic allergic reaction to their first dose. Eligibility: People aged 16-69 who had a systemic allergic reaction to their first dose of COVID-19 vaccine. Design: Individuals who have underlying health issues may need to come to the NIH for screening tests to make sure they are safe to receive the vaccine. People who are eligible to participate in the study will be admitted to the NIH hospital and stay for at least 4 days. They will give urine samples. They will have a nasal swab SARS-CoV-2 test. They will have an intravenous line placed in each arm. They will get the study vaccine (Pfizer-BioNTech COVID-19 vaccine) and one dose of placebo on different days. They will have breathing tests. They may have clinical photography if they develop a rash. Participants will have 4 follow-up visits - 2 by phone and 2 in-person visits at the NIH campus . They will have allergy skin testing at one visit. Drops of different allergens or controls will be placed on their back or arm. The skin under each drop will be scratched with a tool. If the results are negative, a small amount of allergen will be injected just below the surface of their skin. Participants who have no or only a mild allergic reaction to the second dose of the vaccine may be eligible to receive a Booster dose at the NIH. Participation will last for approximately 5 months.
The long-term goal of the study is to mitigate the spread of the pandemic in miners, a population of high-risk, rural essential workers who are susceptible and vulnerable to COVID-19, partly based on exposure to particulate air pollution, and who are predominantly racial/ethnic minorities in New Mexico (NM) (3, 11). The study objective is to provide proof-of-principle for frequent point-of-care molecular testing as a workplace surveillance tool to monitor and prevent the spread of SARS-CoV-2 infection in this unique population. The central hypothesis is that frequent workplace molecular surveillance is an effective method to reduce SARS-CoV-2 infection and discover novel host risk factors for the virus. The site of molecular surveillance (intervention site) will be a surface coal mine in McKinley County, NM, located just outside the Eastern Agency of the Navajo Nation, comprised of 66% minority miners. This site offers a unique opportunity for a community-based study of SARS-CoV-2 infection in this population. Miners at the intervention site will provide nasal swabs before beginning their work shift on alternate days that will be analyzed with a 'screening' molecular test (12). This test is ideal because it is low cost, simple, portable, point-of-care, rapid, and can be performed by minimally trained professionals in low-infrastructure settings. The control site is a similar coal mine in Campbell County, Wyoming (WY). Both mines, operated by the same company, have similar engineering, administrative, and personal protective measures in place. The rationale for this study is to establish the suitability of longitudinal molecular surveillance to prevent and control SARS-CoV-2 infection in this unique population by completing the following specific aims.
THIS IS A PROSPECTIVE OBSERVATIONAL STUDY TO DETERMINE THE ROLE OF PHYSICIAN GESTALT IN CLINICAL PREDICTION OF COVID 19.
This study is a multisite ,grouped test-negative case-control , phase Ⅳ clinical trial of an inactivated SARS-CoV-2 vaccine (CoronaVac) manufactured by Sinovac Research and Development Co., Ltd.The purpose of this study is to estimate the protective effectiveness of complete vaccination (measured ≥14 days after the second dose) of CoronaVac against symptomatic SARS-COV-2 infections ,COVID-19 hospitalizations and severe cases.
