The purpose of this study is to describe the long-term health effects of COVID-19 in a population of mostly Black and Latinx individuals and their households who were diagnosed with COVID-19 at Columbia University Irving Medical Center. In New York, the upper Manhattan and south Bronx communities neighboring Columbia University Irving Medical Center (CUIMC) have been two of the most impacted communities of the COVID-19 pandemic. These neighborhoods are predominantly non-Hispanic black or African American and Latinx. This study will invite people who tested positive for COVID-19 and/or were treated at Columbia University Irving Medical Center to: 1) take a survey to ask about current symptoms and any health problems and 2) ask permission to review COVID-related health history including COVID-19 testing results (from the medical record) since infection to learn about health effects after COVID-19 infection; 3) invite anyone in their household to take a survey; and 4) for up to 500 patients who were hospitalized for COVID, give the option of doing a nasal swab to test for SARS-CoV-2 virus and blood test to check for antibody up to 12 months after diagnosis, to compare how results are different 12 months after infection. The goal is to learn about how the severity of person's infection in 2020 influences long term health effects and how others in their household are impacted by COVID-19.

The novel coronavirus (SARS-CoV-2) infection (COVID-19) has caused a worldwide pandemic. There is still much that is unknown regarding the virus, especially its effects on pregnancy, the fetus, and the neonate. This study seeks to evaluate adverse pregnancy and neonatal outcomes related to COVID-19 infection. The FDA has authorized emergency use authorization for the SARS-CoV-2 messenger ribonucleic acid (mRNA) vaccines from Pfizer and Moderna. Pregnant women were excluded from the Phase III clinical trials of the mRNA vaccines. There are no studies that have evaluated functional antibody responses, antibody reactivity to variant viruses, T cell frequencies or activity, or protection against infection or development of COVID-19. Having a more detailed understanding of how pregnancy and lactation alters the longevity, specificity, and activity of antiviral antibody and T cell-mediated immune responses to COVID-19 mRNA vaccines is essential for the FDA to inform future recommendations and regulation of these vaccines.

COVID-19, the coronavirus disease caused by SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), has led to a global pandemic and has exacerbated existing health inequities among vulnerable populations. Despite higher rates of COVID-19 in Black and Latinx individuals compared to White individuals, rates of testing in predominately non-White, low-income communities are significantly lower than in high-income areas. Self-testing, where individuals collect their own samples, is now feasible for the detection of SARS-CoV-2. One promising approach to increase test uptake is the secondary distribution of self-testing kits, where an individual distributes tests to contacts in their social network and encourages them to self-test. The central hypothesis of this clinical trial is that the secondary distribution of SARS-CoV-2 self-tests can significantly expand test uptake among underserved populations. To test this hypothesis, the investigators will conduct a 1:1 randomized controlled trial that will assess a self-testing intervention that promotes the secondary distribution of SARS-CoV-2 test kits compared with test referrals, with a focus on reaching underserved populations.

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. Type: Interventional Start Date: May 2021 |

This study intends to find out how a cloth mask may impact exercise capacity, to provide guidance for exercisers to adjust their expectations and training accordingly. The investigators plan to asses exercise capacity through estimated peak oxygen consumption (eVO2peak), oxygen saturation and level of perceived exertion during treadmill based exercise while wearing a cloth mask compared to exercising without a cloth mask. The potential significance of this study is to determine if subjects can exercise safely and if their exercise training needs to be adjusted while following the current recommendations of wearing a cloth mask in public. The degree of airflow limitation experienced will depend on the type and fit of the mask being worn, and inadequeate airflow could possibly result in CO2 re-breathing if all air was not fully discharged from the mask with each breath. This re-breathing of CO2 could potentially limit the workload leading to a detriment in performance, and increase in adverse symptoms such as dizziness, lightheadedness, chest pain or shortness of breath that does not improve with rest.

The goal of this pilot clinical trial is to determine feasibility and explore whether financial incentives paid to primary care patients for completing colorectal cancer screening increase completion of colorectal cancer screening. The main questions it aims to answer are: - Do patient financial incentives for completing colorectal cancer screening increase screening completion? - Does a patient financial incentive for colorectal cancer screening offered alongside patient financial incentives for COVID-19 and flu shots increase completion of those shots? Participants who are due for colorectal cancer screening will receive telephone outreach from primary care staff who will offer a stool-based colorectal cancer screening. Participants will be randomly assigned to either Group 1 or Group 2. Group 1 participants will be offered financial incentives for completing COVID-19 and flu shots within 2 months of enrollment. Group 2 participants will be offered financial incentives for completing a COVID-19 shot, a flu shot, and colorectal cancer screening within 2 months of enrollment. Researchers will compare to see if completion of a COVID-19 shot, a flu shot, and colorectal cancer screening is different between the two groups. Type: Interventional Start Date: Nov 2023 |

The goal of this project is to understand the household level transmission dynamics and factors that predict transmission of SARS-COV-2 between pediatric and adults in the household. The novel coronavirus SARS-CoV-2 has spread all around the world and testing has posed a challenge globally. Not much is known about who does and does not acquire SARS-CoV2. It is also unknown who will show symptoms or progress severe disease or death from COVID-19. Children tend to have milder symptoms or none at all. Therefore, few children have ever been tested, so it is unknown if they get the infection as much as anyone else. Health care providers are highly exposed, and they do not get tested unless they show severe symptoms. If groups like children and health workers are infected, they can unknowingly spread SARS-CoV-2, unless they practice behaviors like self-isolation very strictly. The investigators aim to measure the prevalence of SARS-CoV-2 in children and health care workers at a large urban health center. The investigators will also measure how many people in the household of the positive children and health care workers also get SARS-CoV-2 infection. Lastly, the investigators will see what other risk factors affect who acquires SARSCoV-2 from inside or outside of the household clusters. Type: Observational Start Date: Aug 2021 |

Emerging data show that SARS-CoV-2 infection causes gut microbiome changes strongly associated with Post-Acute Sequelae of SARS-CoV-2 (PASC). The investigators and others have established that an orally ingested probiotic (Lactobacillus plantarum 299v, Lp299v) reduces circulating levels of cell-free mitochondrial DNA (cf-mtDNA), decreases toll-like receptor 9 (TLR9) activation [and downstream interleukin (IL-6)], and improves micro- and macrovascular (brachial artery) endothelial dysfunction [as measured by flow-mediated dilation (FMD%)] in humans. Recently published data also report impaired brachial FMD% and increased vascular stiffness post-SARS-CoV-2 infection. Based on these data, the investigators hypothesize that supplementation with Lp299v will attenuate SARS-CoV-2 associated endothelial dysfunction by reducing cf-mtDNA, TLR9 activation, and inflammation.

This study entitled Community-Centered Interventions for Improved Vaccine Uptake for COVID-19 (CIVIC): Getting to Yes, Michigan!, is designed to increase vaccine uptake among populations that experience COVID-19 related disparities. The investigators will focus on the four counties within Michigan where a disproportionate burden of COVID-19 is within African Americans and Latinx communities, i.e., Wayne, Genesee, Kent and Washtenaw Counties. Using a community-based participatory research (CBPR) approach, CIVIC will leverage: its long term relationships with the communities involved, an established CBPR Steering Committee developed and the knowledge gained as a Community Engagement Alliance (CEAL) grant recipient, the resources and networks of the University of Michigan CTSA (MICHR), and the expertise of our academic partners to identify and understand factors that contribute to COVID-19 vaccine hesitancy in African Americans and Latinx communities in Michigan. The investigators will develop and test interventions based on community-centered approaches to achieve a primary goal of increased vaccine uptake. The investigators will achieve this goal with the following aims: 1. Increase understanding of the barriers and drivers of vaccine uptake and hesitancy; 2. Increase vaccine uptake and decrease vaccine hesitancy through the implementation and evaluation of a multi-component intervention; and maintain, enhance, and evaluate the effectiveness of the CIVIC partnership to equitably engage all partners.
