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).

Persistent smell loss that can include diminished or distorted smell function is a common symptom of long COVID syndrome. There are limited treatment options for long COVID-related smell loss. This study aims to determine the efficacy of two at-home treatments, smell training and non-invasive trigeminal nerve stimulation. This study requires participants to conduct daily at-home treatment sessions, attend three in-person study visits at the MUSC Department of Psychiatry and Behavioral Sciences, and complete electronic questionnaires over the 12-week trial, and again at the six-month timepoint. Participants in this trial may benefit directly with an improvement in sense of smell. However, participation may also help society more generally, as this study will provide new information about long COVID-related smell loss and its treatment.

At the University of Iowa, the investigators led a multicenter randomized clinical trial comparing standard prophylactic dose to intermediate dose enoxaparin in hospitalized patients with COVID-19 (NCT04360824). As part of an exploratory biomarker component of this trial, blood samples were collected from hospitalized COVID-19 patients at enrollment and weekly for up to 30 days of hospitalization. The pilot results, as well as reports from other groups, demonstrate increased potential for thrombin generation in the plasma of COVID-19 patients. In particular, in the COVID-19 patient cohort enhanced thrombin generation potential persisted for at least 30 days of hospitalization. The investigators now propose to explore the mechanistic roles of activation of blood cells (such as platelets and neutrophils) and products of cellular activation as mediators of enhanced thrombin generation in patients with COVID-19. The study design will be a longitudinal cohort study, which will allow for the determination of the time course of enhanced thrombin generation potential in relation to clinical outcomes and changes in markers of cellular activation in serial samples obtained from COVID-19 patients for up to 3 years after infection with SARS-CoV-2. This study may provide clues to why a subset of COVID-19 patients present with late thrombotic complications even after apparent recovery from SARS-CoV-2 infection. An ongoing question in the field relates to the comparative prothrombotic effects of acute COVID-19 versus incidental SARS-CoV-2 infection versus acute infection with influenza viruses. Therefore, we will include three categories of hospitalized patients in this study: (1) acute COVID-19, (2) incidental COVID-19, and (3) acute influenza A or B. This project has a strong scientific rationale with direct clinical implications, especially given the emergence of SARS-CoV-2 variants such as delta and omicron that may prolong the pandemic and/or cause surges of COVID-19 in the coming months.

This study will evaluate the safety of administering an additional dose of an mRNA COVID-19 vaccine or mRNA bivalent COVID-19 booster vaccine to individuals who have had adverse reactions to a previous dose or administering an initial dose of an mRNA COVID-19 vaccine to individuals with a personal history of allergic reaction. In addition, this study will evaluate the safety of administering an initial or additional dose or bivalent booster of an mRNA COVID-19 vaccine to individuals experiencing an adverse reaction to a natural COVID-19 infection ("long COVID"). Eligible participants enrolled in this trial will receive an initial or additional dose of either the Pfizer-BioNTech COVID-19 bivalent vaccine or the Moderna COVID-19 bivalent vaccine. Participants will also be required to have 1-2 in person visits along with phone call follow up visits. We hypothesize that individuals who have had adverse reactions to a previous dose of an mRNA COVID-19 vaccine will tolerate an additional dose of the primary mRNA vaccine or bivalent booster, as indicated, and those with a personal history of allergic reaction will tolerate an initial dose of an mRNA COVID-19 vaccine. We also hypothesize that those individuals experiencing an adverse reaction will tolerate an initial or additional dose of a primary mRNA COVID-19 bivalent vaccine, as indicated. The study hypothesizes that individuals that have had adverse reactions to a dose of an mRNA COVID-19 vaccine will tolerate an additional dose and those with a personal history of allergic reaction will tolerate vaccination with an mRNA COVID-19 vaccine.

Preliminary evidence suggests that cognitive impairment is a common outcome experienced by individuals surviving Covid-19 (1-5). Cognitive impairment following Covid-19 which leads to critical illness is not surprising and perhaps even expected. However, significant cognitive deficits appear to be common even among individuals testing positive for Covid-19 who were never hospitalized. Questions exist regarding the mechanisms of the aforementioned cognitive impairment. The association between COVID-19 and brain dysfunction is not surprising since SARS-CoV has been found in the brain and because Coronaviridaes (CoVs) have been associated with central nervous system (CNS) diseases such as acute viral encephalopathy, acute disseminated encephalomyelitis, and multiple sclerosis (6-11).The possible brain entry routes for CoVs include either direct intranasal access to the brain via olfactory nerves or indirect access by crossing the blood-brain barrier (BBB) via hematogenous or lymphatic spread (9).

Background: Most people who get COVID-19 seem to recover with no long-term effects. However, some people who recover from acute COVID-19 infections report lingering symptoms. This is called long COVID. Many people with long COVID report symptoms related to the nervous system; these can include problems with fatigue, speech, and memory. Objective: To test motor memory in people with long COVID, compared to healthy volunteers. Eligibility: People aged 18 to 90 years who are also enrolled in study protocol 000089. Healthy adults are also needed. Design: Participants will be screened by telephone. They will confirm they are able to type without discomfort using their nondominant hand. They will confirm they have access to a computer connected to the internet. All study tasks will be done online. Participants will complete 2 tasks in 2 days. Participants will be sent a link to a website. The website will give them instructions. They will place the fingers of their nondominant hand over 4 numbers on the keyboard and type a sequence (eg, 4-1-3-2-4). They will type this sequence as often as they can in 10 seconds. Then they will rest for 10 seconds before repeating the task. They will repeat this pattern for 15 minutes. After they finish the typing task, participants will take a 10-minute questionnaire. They will answer questions about their experiences with COVID-19 and memory issues; they will say which hand they use for tasks such as brushing their teeth or throwing a ball. Participants will get a notice to repeat the typing task 22 hours after they finish the first one. They should complete the second task within 28 hours....

Background: COVID-19 affected African Americans more than Whites. African Americans, especially women, have had higher rates of COVID-19 infections compared to Whites. They are also more likely to go to the hospital or die of this disease. Many researchers who looked into these issues lacked background data on the people they studied. SELF is a 10-year study of fibroids in African American women aged 23-35. Researchers already have a lot of data on these women. Asking how COVID-19 affected them can add context other studies lack. Objective: To describe the impact of the COVID-19 pandemic on young African American women and their families. Eligibility: Participants must be enrolled in SELF (Study of Environment, Lifestyle, and Fibroids). Design: Researchers will invite all women enrolled in SELF to participate in this natural history study. Participants will complete one questionnaire. They will answer the questions online.

The study staff will conduct a hybrid type 1 effectiveness implementation 2-arm trail with 360 Black young adults from Alabama, Georgia, and North Carolina. Participants will be randomized to receive the standard of care (control) or the TT-C intervention arm, each with a balance of 180 participants. Primary effectiveness outcome is COVID-19 vaccine uptake define as receipt of any vaccine (primary series or secondary booster). Secondary effectiveness outcomes are vaccine hesitancy, confidence, and knowledge, attitudes, and beliefs. The study staff will also conduct qualitative interviews with a group of purposively selected AA-YA participants (est. n=12-16) and site staff (est. n=6-8) to assess barriers and facilitators to implementation. The hypothesis is that the intervention arm will be more effective than the control arm at increasing vaccine uptake.

Individuals susceptible to SARS-CoV-2 and the illness it causes (COVID-19) are comprised of heterogeneous populations with a large risk spectrum for more severe disease. Pre-existing risk factors for a more severe course include respiratory and cardiovascular disease, morbid obesity, diabetes, underlying kidney or liver disease, and immunocompromised status. Whether children and young adults with inflammatory bowel disease (IBD) or juvenile idiopathic arthritis (JIA) receiving immunomodulating biologic and other therapies which are known to increase risk of viral infection are at increased risk of complications from COVID-19 or post-infectious co-morbidities, including the recently described multi inflammatory syndrome (MISC), is entirely unclear. This research focuses on the heretofore uncharacterized immune response to SARS-CoV-2 infection in children and young adults with IBD or JIA who are receiving maintenance immunosuppressive biologic therapies. Given the large Connecticut based infusion program, in a region of the United States with a recent large outbreak of COVID-19, the investigators have a unique opportunity to address a glaring knowledge gap in this unique pediatric, adolescent, and young adult population. The investigators will longitudinally determine antibody development and durability to SARS-CoV-2 in approximately 450-500 children and young adults with IBD or JIA receiving biologic therapy using a highly sensitive and specific quantitative assay utilizing novel technology. This period will include a return to school or work for many with likely resurgent infections, as well as the possible introduction of anti-SARS CoV-2 vaccines. The specific aim is to study the acute and convalescent antibody responses to SARS-CoV-2 infection in a cohort of children and young adults receiving infusions of biologic therapies for IBD and JIA.

This is a phase I trial followed by a phase II randomized trial. The purpose of phase I study is the feasibility of treating patients with acute respiratory distress syndrome (ARDS) related to COVID-19 infection (COVID-19) with cord blood-derived mesenchymal stem cells (MSC). The purpose of the phase II trial is to compare the effect of MSC with standard of care in these patients. MSCs are a type of stem cells that can be taken from umbilical cord blood and grown into many different cell types that can be used to treat cancer and other diseases. The MSCs being used for infusion in this trial are collected from healthy, unrelated donors and are stored and grown in a laboratory. Giving MSC infusions may help control the symptoms of COVID-19 related ARDS.

Low doses of radiation in the form of chest x-rays has been in the past to treat people with pneumonia. This treatment was thought to reduce inflammation and was found to be effective without side effects. However, it was an expensive treatment and was eventually replaced with less expensive treatment options like penicillin. The COVID-19 virus has emerged recently, causing high rates of pneumonia in people. The authors believe that giving a small dose of radiation to the lungs may reduce inflammation and neutralize the pneumonia caused by COVID-19. For this study, the x-ray given is called radiation therapy. Radiation therapy uses high-energy X-ray beams from a large machine to target the lungs and reduce inflammation. Usually, it is given at much higher doses to treat cancers. The purpose of this study is to find out if adding a single treatment of low-dose x-rays to the lungs might reduce the amount of inflammation in the lungs from COVID-19 infection, which could reduce the need for a ventilator or breathing tube.
