Background: SARS-CoV-2 is the virus that causes COVID-19. Some people who recover from an acute COVID-19 infection may continue to have symptoms that persist for months or years. These can include neurological symptoms, such as headaches, loss of taste or smell, dizziness, or trouble walking. Pembrolizumab is a drug approved to treat certain cancers. Researchers think this drug might reduce long-term neurologic symptoms after a COVID-19 infection. Objective: To test pembrolizumab in people with ongoing neurologic symptoms of COVID-19. Eligibility: People aged 18 years or older who had COVID-19 at least 6 months ago and have ongoing neurologic symptoms. Design: Participants will have 7 clinic visits in 7 months. Participants will be screened. They will have a physical exam with blood tests. Swabs will be used to collect cells from inside the mouth and nose. They may opt to have an imaging scan. Participants will also have other tests before they are given the study drug. These include eye and skin exams; tests of their memory and thinking; and tests of involuntary body functions, such as heart rate, blood pressure, sweating, and digestion. Their grip strength and walking pace will be measured. They will wear a heart rate monitor for 24 hours. They will wear devices on a wrist and thigh to measure activity for 10 days. Participants will have a lumbar puncture (spinal tap): A thin needle will be inserted into their lower back to draw out a sample of the fluid around their spinal cord. Pembrolizumab is given through a needle inserted into a vein. Participants will receive 1 dose of the drug. Participants will have 4 follow-up visits over 6 months. Tests may be repeated during these visits.

The CDC describes Post-acute sequelae of SARS-COV-2 infection (PASC) for the wide range of physical and mental health consequences experienced by some patients. These sequelae may be present four or more weeks after SARS-COV-2 infection, including patients who had initial mild or asymptomatic acute infection. However, there is complete absence of data whether chronic sleep changes due to COVID-19 infection may influence these physical and mental health consequences. While fatigue is one of the common post-COVID conditions, there are no systematic examinations of sleep disturbances in COVID-19 survivors. This will be a pilot observational retrospective and prospective cohort study, to systematically assess if sleep disturbances and severity of sleep apnea comprise a modifiable facet of PASC as well as the short-term and longer-term effects of COVID-19 infection itself on sleep, cognitive function, exercise capacity and lung function.

The COVID-19 pandemic has transformed healthcare delivery; arguably, the fields of obstetrics and pediatrics have experienced some of the greatest changes as they have transitioned away from their role as a medical home and into more of an urgent care model of care. Baby2Home is a digital health intervention designed to bridge the resultant gaps in obstetrics and pediatrics healthcare services for new families over the first year of life. This randomized controlled trial will evaluate whether, compared to usual care, Baby2Home 1) improves maternal, paternal, and infant health service utilization outcomes over the first year postpartum, 2) improves maternal and paternal patient reported outcomes, and 3) reduces racial/ethnic and income-based disparities in preventive health services utilization and parental patient reported outcomes.

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.

Latinx communities are disproportionately affected by the COVID-19 pandemic, with Spanish-speaking Latinx communities carrying even heavier burdens of infection, hospitalization, and mortality. Major barriers to COVID-19 testing and vaccination exist, and a profound need remains to understand and address the social, ethical, and behavioral implications (SEBI) of COVID-19 testing and vaccination within Latinx communities. Our community-academic partnership proposes a rigorous mixed-methods, community-based participatory research study to better understand the SEBI of COVID-19 testing and vaccination and to refine and test a novel and culturally congruent intervention that integrates two evidenced-based strategies - peer navigation and mHealth - to increase COVID-19 testing and vaccination within Spanish-speaking Latinx communities.
