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.

Given the likelihood of COVID-19 remaining an endemic disease among high-risk populations, establishing effective mitigation interventions will be critical to stemming community transmission. Criminal justice-involved individuals are extremely important to reducing community-based SARS-CoV-2 transmission due to their increased risk of contracting SARS-CoV-2 while incarcerated and their likelihood of living in congregate settings after incarceration. The investigators will evaluate an onsite Point-of-Care SARS-CoV-2 testing and education strategy in a corrections-focused community-based organization and its impact on improving testing uptake, mitigation behaviors(e.g. mask wearing, hand hygiene, social distancing, vaccine uptake when available), and cost-effectiveness.

Parasympathetic nervous system (PNS) is part of the body's autonomic nervous system(PNS) protects body against inflammation. Study shows that reduced PNS function activity is associated with persistent inflammation. Preliminary data from the studies shows, that post-COVID-19 POTS patients have reduced parasympathetic (PNS) function. Given that the PNS protects against inflammation, this clinical trial aims to prove that post-COVID-19 POTS is caused by reduced PNS activity, which in turn, contributes to persistent inflammation, orthostatic intolerance, and OI symptoms. The study will evaluate immune cell activation in post-COVID-19 POTS and patients with history of COVID-19 infection without sequelae and correlate this with the degree of decreased PNS activity.

COVID-19 is a systemic inflammatory disease involving many organs including the lungs, vascular system liver and myocardium that lead to severe pathologies. Patients with severe cardiopulmonary symptoms usually require weeks to months to fully recover. Studies of clinical and subclinical impairments of COVID-19 patients are important for medical practice and public health as well as providing pathogenic insight to the viral infection and secondary immune response. Chronic damage of vital organs and systems, and the potential long-term effects is of serious concern. In this study the investigators plan to quantify and characterize chronic consequences of COVID-19 in individuals who receive similar medical care related to disease severity and duration in a single health care system. Using state-of-the-art Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) technology, we will study the pathology in major organ systems in comparison to matched controls. The results of this study may facilitate measures to prevent, detect, and manage complications from COVID-19 infections.

Some people who have been infected with the virus that causes COVID-19 can experience long-term effects from their infection, known as post COVID-19 conditions (PCC) or long COVID1. The medical circles often describe it as post-acute sequelae of Covid-19 (PASC). People with post-COVID conditions can have a wide range of symptoms that can last more than four weeks or even months after infection. Sometimes the symptoms can even go away or come back again. The Centers for Disease and Prevention (CDC) listed a constellation of 19 symptoms related to post COVID-19. In research, brain fog is prominent among the most reported neurological symptoms which also include, numbness, tingling, headache, dizziness, blurred vision, tinnitus, and fatigue that last more than a year post-infection. Vielight Inc. has developed a compact and portable device named the "Vielight RX Gamma", which is suitable for home use. The intervention is based on the science of photobiomodulation (PBM) which utilizes certain light energy to modify cellular functions. The fundamental mechanisms of PBM are based on the absorption of photons by the mitochondria to modulate cellular functions. The Vielight Neuro RX Gamma delivers light of specific wavelengths (810 nm), power and duration to the brain/nasal cavity to achieve this. The biological process involves numerous interacting mechanisms that modulate bodily functions. One result of PBM is the benefits it could offer the post COVID-19 (long COVID) population. The Vielight Neuro RX Gamma emitting NIR might reduce inflammatory markers relevant to COVID-19 and since it pulses at 40 Hz can activate the non-inflammatory M2-genotype microglia to remove markers of Alzheimer disease, such as beta-amyloid and possibly tau deposits. Using Vielight Neuro RX Gamma, the same activation of non-inflammatory markers might occur with post COVID-19 (long-COVID) patient population as well as the reduction in the brain fog. This trial utilizes a completely remote and virtual design. It is a double blind randomized controlled trial that is expected to involve 36 participants who are confirmed to have Post- COVID cognitive impairment. Eighteen of the participants will be randomized to the active Vielight RX Gamma protocol, and the other eighteen participants will be randomized to the sham Vielight RX Gamma regimen. The trial will study patients over 120 days and ask them to track their symptoms in a daily survey.

The overall goal of this project is to advance the understanding of underlying mechanisms impacting performance fatigability and perceived fatigability in Veterans with post-COVID-19 fatigue and explore the safety and feasibility of a home-based "minimal-dose" resistance exercise program in this population. The central hypothesis is that declines in force capacity, skeletal muscle oxygen extraction, and affective responses to physical activity offer potential mechanisms through which fatigability is increased in Veterans with post-COVID-19 fatigue. Moreover, home-based resistance exercise delivered remotely may provide a safe and feasibility treatment option for targeting neuromuscular and neurobehavioral factors influencing fatigability severity in this population.
