Covid-19 is an additional stressor Black women have to deal with that may interfere with hypertension self-care management. Social connectedness is a source of resilience for Black women to promote mental and physical health. Unfortunately, in the face of the Covid-19 pandemic, social distancing is a challenge further isolating Black women from their networks. How is social connectedness to manage stress and emotional well-being in a social-distancing society for Black women with hypertension? The research team proposed a synchronous web-based version of Enhanced Co-Created Health Education InterventioN (eCo-CHIN) that build the success and best practices derived from the original intervention. A Covid-19 session will be included as a way of helping Black women to maintain resilience and self-care during stressful times. The eCo-CHIN intervention is innovative and timely because the research team are using a synchronous platform preparing Black women on how to deal with Covid-19 while taking care of self. The primary investigator for this pilot study (Dr. Wright) is a Black Early Stage Investigator and former KL2 (career development) awardee. The interdisciplinary research team has the expertise and resources to deliver this Enhanced Co-CHIN intervention.

Background: COVID-19 is a worldwide pandemic and currently there is no effective therapy or vaccine. SARS-CoV-2, the virus that causes the COVID-19 respiratory infection, appears to be very contagious however all the modes of transmission are unclear. Transmission may occur in up to 25 percent of cases when there are no symptoms (asymptomatic). Before there are any symptoms, droplet spray during speaking may increase transmission from person to person; most of the spray is saliva. Researchers at the NIH would like to test saliva for the virus before symptoms are reported. Additionally, they would like to examine the importance of using masks to prevent transmission. They hope to better understand how COVID-19 is spread among people and how it can be prevented. For this study they would like to collect samples from the nose (nasopharyngeal swab), mouth (spit sample), eye (conjunctival fluid) and blood to test for the virus and if it is contagious. Objectives: To determine if the SARS-CoV-2 virus is present in saliva in asymptomatic individuals who are COVID-19 positive. To determine if using masks can prevent transmission. Eligibility: People ages 18 and older without symptoms or with mild symptoms (e.g., low grade fever, mild malaise, minor sore throat, runny nose, or sneezing) who have been in close contact (e.g. live in the same house) with someone who has tested positive for COVID-19 or people who have tested positive for COVID-19 and have mild (e.g., low grade fever, mild malaise, minor sore throat, runny nose, or sneezing) or no symptoms. Design and Procedures: For screening, interested participants will contact a study team member. The interested participant will be asked to provide documentation of COVID-19 positive status, their symptoms, or their contact to a COVID-19 positive person. Participants will be asked to come to the NIH drive-up COVID-19 testing site or NIH Clinical Center (Bethesda, MD) for 2 or more visits in 15 days for the following procedures: nasal swab for COVID-19 and viral load, verbal symptom assessment, saliva collection, and speaking exercise to capture oral fluid. During this time, participants will also be asked to participate in phone calls with the study staff and to complete questionnaires electronically. Participants will have weekly telephone calls to discuss their symptoms and 2-5 drive-up visits to the NIH within 28 days. If visits are scheduled at the Clinical Center, participants will have the option to participate in providing blood sample(s), a conjunctival swab and 1-2 salivary gland biopsies. If a participant has tested positive, they may be asked to return to the NIH after they have recovered from COVID-19 for additional sampling. The following procedures are part of this research: - Speaking exercise - participants will be asked to read a short script with and without wearing a mask. The droplets they produce while they speak will be collected. - Saliva collection - participants will spit into a cup and have saliva collected from different areas of the mouth. They should not eat 90 minutes before this but drinking water or juice is acceptable. They may have their tongue painted with a sour liquid to increase their saliva. - Nasal swab- participants will have a swab rubbed inside their nose. - Nasopharyngeal swab - participants that are close contacts of COVID-19 positive individual(s) and need a COVID-19 test, will have a swab inserted through the nose to rub the back of their throat. - Questionnaires - participants will complete questionnaires about their symptoms electronically at home. The following procedures are optional for participants to agree to participate in and will be performed in the Clinical Center: - Blood sample(s) - participants will have blood collection via venipuncture. - Conjunctival swab - participants will have the inner lower eyelid wiped with swab. - Minor salivary gland biopsy - participants will have tiny glands in mouth removed. Procedure will be done in the hospital. Participants will be paid up to a total of $300 for the study, based on the number of visits to NIH and the types of procedures performed. Payment will be: $50 on Day 1, Day 15 and at the recovery visit. Participants who agree to the optional conjunctival swab and/or biopsy will be paid $50 for each conjunctival swab (up to 1) and/or $50 for each salivary biopsy (up to 2). If at any time the participants start to have moderate or severe respiratory symptoms, their participation in the study will end and they should seek care with their local provider.

Background: Vaccines against SARS-CoV-2, the virus that causes COVID-19, have been highly effective against preventing severe disease. But the protective effects of these vaccines appear to wane over time. Researchers want to learn why. Objective: To learn more about how the immune system responds to vaccines against infections like SARS-CoV-2. Eligibility: Healthy adults ages 18 or older who are scheduled to receive either a new vaccine or a booster shot against SARS-COV-2 or another emerging infection. Design: Participants will be screened with a medical history and blood and urine tests. Participants will have up to 8 study visits in 1 year. Each visit should last less than 2 hours. At each visit, participants will give blood samples. Some blood samples will be used for genetic testing. They will also give updates on their health. After the first study visit, participants will receive either a first vaccination or a booster shot. They must get the vaccine in their community or workplace. They will not get the vaccine at NIH. This study currently focuses on SARS-CoV-2, but it will expand to other infectious diseases as they emerge and become the target of new vaccines. ...

The platform protocol is designed to be flexible so that it is suitable for a range of study settings and intervention types. Therefore, the platform protocol provides a general protocol structure that can be shared by multiple interventions and allows comparative analysis across the interventions. For example, objectives, measures, and endpoints are generalized in the platform protocol, but intervention-specific features are detailed in separate appendices. This platform protocol is a prospective, multi-center, multi-arm, randomized controlled platform trial evaluating potential interventions for PASC-mediated sleep disturbances. The hypothesis is that symptoms of sleep and circadian disorders that emerge in patients with PASC can be improved by phenotype-targeted interventions. Specific sleep and circadian disorders addressed in this protocol include sleep-related daytime impairment (referred to as hypersomnia) and complex PASC-related sleep disturbance (reflecting symptoms of insomnia and sleep-wake rhythm disturbance).

The primary objective of this effort will be to optimize and operationalize innovative passive surveillance systems and in parallel, the effort will identify, evaluate, and transition groundbreaking new technologies in diagnostics for operationalization. To meet the objective and execute the deliverables for this program of effort, the A&M Breathalyzer PROTECT Kiosk will be tested, modified and validated at Brooke Army Medical Center (BAMC). The collaborative efforts between the PI, Dr. Michael Morris at BAMC and Co-Investigator Dr. Tony Yuan at USU- Center for Biotechnology (4D Bio3) will assess the passive detection technology and provide a capability survey of use-case scenarios for different operational settings. Goals: 1. Optimization and operationalize the A&M Breathalyzer PROTECT Kiosk, portable mass spectrometer (MS) Detector for Deployment in Military Operational Medicine Environments. The Breathalyzer will be deployed to BAMC to test its detection capabilities of COVID-19 among symptomatic and asymptomatic COVID-19 carrier vs. those not infected compared to gold standard RT-PCR. 2. Evaluate the passive sensing, breath capture system, built within the A&M Breathalyzer PROTECT Kiosk. The conversion of the active breath capture system, currently requires a straw that the subject breaths into, where then a series of sensors built in the Breathalyzer would automatically sample the exhaled breath within proximity for recent COVID-19 exposure. This task would conclude with a set of sensors and sensor inputs that would be analyzed by the Atomic AI platform built in the device. Field testing at BAMC is planned to determine the level of detection and discrimination for sensor combinations to SARS-CoV2 components and biomarkers detected. This testing would update the Atomic AI algorithm, within the device, to understand the accuracy of positive detection and the resulting sensitivities.
