The proposed project will implement and evaluate a brief Community Health Worker (CHW) intervention through the Albany Area Primary Health Care, a rural Federally Qualified Health Center (FQHC). The primary goal of this study is to maximize effective outreach, education, and communication through CHWs in order to facilitate improved COVID-19 vaccine confidence and uptake in underserved and vulnerable communities. CHWs will be deployed to the homes of adults with increased risk of morbidity and mortality (i.e., African Americans or Latinos with uncontrolled diabetes or prediabetes, age <50 years, and non-COVID-19 vaccinated) in order to educate them about diabetes, COVID-19 and related vaccines. Health assessments, including blood glucose measurement, will be conducted on the indexed patient and offered to all other adult family members in the household (i.e., "bubble"). Adults with Type 2 diabetes likely live in households with other adults who have or are at increased risk for diabetes (i.e., prediabetes and obesity).1 It is expected that they will also share similar COVID-19 exposure risk. The specific aims are to: 1) Evaluate a community-driven education program to increase and enhance COVID-19 vaccine confidence and uptake in individuals with uncontrolled diabetes and their families (i.e., their "bubble") and 2) Evaluate a community-driven education program to improve diabetes self-management behaviors and related outcomes (e.g., blood glucose) in individuals with uncontrolled diabetes in rural, Southwest Georgia.

COVID-19 can trigger a dysregulated immune response, and previous studies have shown that immune modulation can improve outcomes in hospitalized patients. This trial is designed to determine whether intensification of immune modulation early in the course of the disease (while patients are on low flow oxygen) with abatacept (active arm) combined with standard of care (SOC) improves recovery as compared with placebo + SOC (placebo arm). For both groups, intensification of immunomodulation will be provided as part of SOC in case of signs of disease progression (patient requires high flow nasal oxygen (HFNO) or more support) and/or if the patient has rapidly increasing oxygen requirement.

This study is a cooperative investigation funded by the NIH. The project is a collaboration among three major NIH Clinical Translational Science Awardees: 1) UCI (lead site with its affiliate CHOC), 2) Northwestern University (with its affiliate Lurie Children's Hospital), and 3) USC (with its affiliate Children's Hospital of Los Angeles). There is an increasing number of children who, through medical advances, now survive diseases and conditions that were once fatal, but which remain chronic and debilitating. A major challenge to improve both the immediate and long term care and health of such children has been the gap in our understanding of how to assess the biological effects of exercise. Like otherwise healthy children, children with chronic diseases and disabilities want to be physically active. The challenge is to determine what constitutes safe and beneficial level of physical activity when the underlying disease or condition [e.g., cystic fibrosis (CF) or sickle cell disease (SCD)] imposes physiological constraints on exercise that are not present in otherwise healthy children. Current exercise testing protocols were based on studies of athletes and high performing healthy individuals and were designed to test limits of performance at very high-intensity, unphysiological, maximal effort. These approaches are not optimal for children and adolescents with disease and disability. This project (REACH-Revamping Exercise Assessment in Child Health) is designed to address this gap. Cohorts of children will be identified with two major genetic diseases (CF and SCD) and measure exercise responses annually as they progress from early puberty to mid or late puberty over a 3-4year period. In addition, in the light of the pandemic, a group of children will be added who were affected by SARS-CoV-2 and investigate their responses to exercise. SARS-CoV-2 has similar long-term symptoms than CF and SCD have. Novel approaches to assessing physiological responses to exercise using advanced data analytics will be examined in relation to metrics of habitual physical activity, circulating biomarkers of inflammation and growth, leukocyte gene expression, and the impact of the underlying CF, SCD or SARS-CoV-2 condition. The data from this study will help to develop a toolkit of innovative metrics for exercise testing that will be made available to the research and clinical community.

The goal of this real world efficacy study is to understand the benefit of universal social needs screening, community-based service referrals, and telephonic follow-up as a scalable strategy for preventing COVID-19 transmission, and for addressing the secondary health effects of the social, behavioral, and economic changes following the COVID-19 pandemic. With statewide community service providers, existing health information technology, and piloted methods, we seek to determine the effectiveness of universal social needs screening and community service referrals - the SINCERE intervention - in improving health outcomes of COVID-19 vulnerable and socioeconomically disadvantaged populations and whether intensive follow-up and collaborative goal-setting helps overcome barriers to community service use by patients seen in the emergency department and seeking COVID testing at community-based and mobile clinic locations.

Background: COVID-19 is an acute respiratory syndrome. One symptom of COVID-19 is a reduction in the number of cells called lymphocytes in the blood. Lymphocytes are a type of white blood cell that fights infections. With fewer lymphocytes, the body cannot effectively fight back against SARS CoV-2, the virus that causes COVID-19. Researchers want to better understand how SARS-CoV-2 affects these blood cells. This information may give them ideas for new treatments. Objective: To learn more about how SARS-CoV-2 affects lymphocytes, the immune, and the blood clotting system. Eligibility: Adults age 18 and older who either currently have COVID-19 or have recently recovered from it Design: Participants will give a blood sample. For this, a needle is used to collect blood from an arm vein. For participants who have a central line, blood will be collected through that instead. Participants medical records related to COVID-19 will be reviewed. Participants who have recovered from COVID-19 will be asked to undergo leukapheresis to collect white blood cells. For this, blood is taken from a needle placed in one arm. A machine separates out the white blood cells. The rest of the blood is returned to the participant through a needle placed in the other arm. This takes about 2-3 hours. Recovered participants may have material collected from inside the nostrils and/or rectum. This is done by gently rubbing the area with a sterile cotton swab. Recovered participants may have an echocardiogram to look at their heart. For this, a small probe is held against the chest to get pictures of the heart from different angles. This takes less than 30 minutes. Participation lasts 1-2 days on most cases and may be split in a few visits for recovered patients if leukapheresis and echocardiogram are done. ...

Background: COVID-19 is an infection caused by a coronavirus. It can affect different parts of the body. For most people, it causes fevers or trouble breathing. Some people can have symptoms long after they recover. Researchers want to learn if there are signs of changes in the nervous system that may be related to COVID-19. Objective: To test the nervous system (the brain and nerves) in people who have had COVID-19 yet still have certain symptoms even after recovering. Eligibility: People age 18 and older who had COVID-19 and still have neurologic symptoms after they recovered from the initial infection. Design: Participants will be screened with a medical record review. Participants will have a neurological exam. They will complete pen-and-paper tests of their memory and thinking. They will complete a smell test with 'scratch-and-sniff' booklets. They will give blood samples. Participants will have magnetic resonance imaging (MRI) of the brain. Soft padding or a coil will be placed around their head. They will lie on a table that slides in and out of the MRI scanner. They will get a contrast dye through an intravenous (IV) catheter. Participants blood pressure, blood flow, skin temperature, sweating, and breathing will be monitored. Participants will have an electrocardiogram to measure heart function. Participants will blow into a mouthpiece for several seconds. Participants will lie on a table that has a motor. The motor tilts the table. Participants will have blood drawn through an IV as the table tilts. Participants will have a lumbar puncture. A small needle will be inserted into the spinal canal to obtain fluid. Participants may repeat some tests 8 weeks to 1 year later.

Background: The SARS-CoV-2 virus has caused a pandemic infection called COVID-19. It is a global threat to people, communities, and health systems. Researchers are concerned about the mental health effects of the pandemic. They want to learn more about how it is affecting people s alcohol use and problems, and how it may continue to affect them over time. Objective: To study the impact of the COVID-19 pandemic on alcohol use and consequences in individuals across the spectrum of alcohol use and those with alcohol use disorder. Eligibility: Participants who have been screened under the NIAAA Screening, Assessment and Management Protocol (14-AA-0181) Design: Participants will complete a baseline survey by phone. It will ask about alcohol use, alcohol dependence, and stress. It covers 2 time periods: the 12 months before the pandemic started and the time since it started. Participants will get an ID code and a link to an online survey. They will complete the online survey within a week of the phone survey. Participants will complete a series of online surveys over 24 months. For the first year, surveys will be completed weekly for the first 4 weeks, then biweekly for the next 8 weeks, and then every 1-2 months for the rest of the year. For the second year, surveys will be completed every 6 months. Surveys will cover the following topics: - Alcohol use and its consequences - Other substance use - Stress - Impact of the COVID-19 pandemic - Pain - Physical health - Sleep - Quality of life. Because the course of the pandemic may change, the frequency of the surveys may change. Participation lasts 2 years.

The study will test two tactics to improve uptake of two vaccines in adults. The vaccines prevent COVID-19 and influenza. Both are common and harmful. Most adults do not get either vaccine. This is despite strong recommendations that all adults get both vaccines. The study will involve adult patients at eight Mayo Clinic primary care practices in Rochester and Kasson. The study will test the two tactics together. Four clinics will get the two tactics. The other four clinics will not. The study will randomly assign the two tactics to the clinics. One tactic is to send a letter by US mail to the patient. The letter will state strong recommendations on getting both vaccines now. It will tell patients how to get the vaccines now. The second tactic is to send monthly emails to clinicians. It will remind them to use every visit to vaccinate patients against COVID-19 and influenza. The study will compare the uptake of the two vaccines after six months in the clinics with and without the two tactics.

The goal of this clinical trial is to find out which approach works better in getting more of the friends and connections of Latino adults get vaccinated against COVID-19. The main questions this study aims to answer are: 1. Can teaching people to use motivational interviewing help more friends and connections of Latino adults get the COVID-19 vaccine compared to just giving information about the vaccine? 2. What are the things that make it easier or harder for Latinos and networks to get the COVID-19 vaccine? 3. How does this intervention work in practice so that it can be made available to more people in the future The researchers will compare the vaccine rates of the friends and connections of Latinos who have been trained in motivational interviewing with those who have only been given information about the COVID-19 vaccine. This will help figure out which method works best to encourage more people to get vaccinated.

This platform protocol is designed to be flexible so that it is suitable for a wide range of settings within health care systems, for remote settings, and in community settings where it can be integrated into COVID-19 programs and subsequent treatment plans. This protocol is a prospective, multi-center, multi-arm, randomized, controlled platform trial evaluating potential interventions for PASC-mediated cognitive dysfunction. The hypothesis is that PASC-associated dysfunction in cognitive domains, such as executive function and attention, may be improved by interventions that selectively focus on enhancing those domains. This design seeks to evaluate each intervention relative to the Active Comparator. The BrainHQ (alone) arm is important because the intervention is commercially available, accessible, relatively inexpensive, and does not require trained personnel to administer. BrainHQ has been also been proven effective in other studies of cognitive dysfunction such as studies in aging, mild cognitive impairment, traumatic brain injury, among others. The BrainHQ + PASC CoRE arm and the BrainHQ + tDCS arms are suspected to provide cognitive improvements beyond BrainHQ alone through different mechanisms. Both PASC CoRE and tDCS have extensive prior use and have demonstrated utility in improving aspects of cognitive function in other clinical settings..
