Growing evidence indicates that many people who have chronic post-acute sequelae of SARS-CoV-2 infection (PASC) will experience ongoing neurological and musculoskeletal impairment that can affect gait and balance. Identifying the factors contributing to these impairments and how they influence functional mobility is the first step towards creating effective evaluation and treatment protocols. In this study the investigators will examine cognition, vision, proprioception, muscle strength, gait and balance in persons with and without PASC to understand how PASC may impact functional mobility through a cognitive-sensorimotor lens. Gait and balance will be studied in environments that stress cognitive and sensory abilities. Study outcomes will be critical for the development of evidence-based Veteran Health Administration diagnostic and standard-of-care protocols to address gait and balance dysfunction in Veterans with PASC for restoring their functional mobility and independence.

Researchers are looking for other ways to prevent severe illness from COVID-19. COVID-19 is a virus that most often causes mild flu or cold-like symptoms. However, people with certain health conditions or other factors have a high risk (chance) of getting severely ill from COVID-19, which can require a hospital stay or lead to death. Some people who are high risk for severe illness may be unable to take certain treatments for COVID-19 because they are not available to them, or they take other medicines that may react with a treatment and cause an unwanted effect. Molnupiravir (MK-4482) is a study medicine designed to stop the COVID-19 virus from copying itself in the body (multiplying). The goal of this study is to learn if molnupiravir prevents severe illness from COVID-19 more than placebo in people who are high risk.

Diaphragm is the principal muscle of inspiration. Diaphragmatic dysfunction is seen in many conditions including following intubation, lung disease, prolonged ventilation, neuromuscular disease, phrenic nerve injury. The possible mechanisms of diaphragmatic dysfunction in patients with COVID19 are critical illness myopathy, ventilator-induced diaphragm dysfunction, iatrogenic phrenic nerve injury particularly secondary to line placement, post-infectious inflammatory neuropathy of the phrenic nerve, or possibly direct neuromuscular involvement of the SARS- CoV-2 virus given expression of the angiotensin- converting enzyme 2 (ACE2) receptor in the peripheral nervous system and skeletal muscle. The use of diaphragmatic ultrasound has been widely used to assess diaphragmatic function is well known in patients following prolonged mechanical ventilation. Prolonged mechanical ventilation leads to contractile dysfunction of respiratory muscles, in particular the diaphragm, causing a so-called ventilator-induced diaphragm dysfunction. The latter is defined as a loss of diaphragm force-generating capacity specifically related to the use of mechanical ventilation. However, the use of diaphragmatic Ultrasound to assess its function in Long COVID patients has not been noted and is a gap in the work up of these patients. The purpose of this study is to address Diaphragmatic Dysfunctional (DD) breathing seen in patients with Post-Acute Sequelae of COVID-19 (PASC), which results in shortness of breath/chest tightness and subsequent fatigue. Targeting shortness of breath and subsequent fatigue as a central symptom of PASC will alleviate long term sequelae for the patients with PASC. DD will be addressed by a unique intervention of physical therapy. The goal of this prospective randomized clinical study will be to evaluate the comparative treatment effect of DB on markers, specifically fatigue, dyspnea, 6 min walk test, depression/anxiety, and quality of life (QoL).

SCALE-UP Utah is a community-academic partnership to address COVID-19 among Utah community health centers. The long-term objective of the project is to increase the reach, acceptance, and uptake of COVID-19 vaccines among Utah's Community Health Center patient population. The study will compare two practical, feasible, scalable interventions to increase COVID-19 vaccine uptake in Utah Community Health Centers: 1. Text Messaging (TM): population health management (PHM) intervention that analyzes EHR data to automatically identify patients eligible for COVID-19 vaccination and uses bi-directional text messaging to help connect patients to a vaccination site; 2. Patient Navigation (PN): PHM intervention to increase vaccination uptake among eligible patients (identified via TM) using patient navigation (e.g., motivating patients, addressing logistics and barriers). The project will employ a rapid cycle research approach in which interventions are tested on a small scale, using short time frames (e.g., <1 month) and cyclical evaluation cycles.This process involves implementing intervention messages with a small number of clinics or patients, evaluating the outcomes, and either adapting the intervention messages based on findings (and retesting) or disseminating effective approaches to additional clinics or patients. A critical feature of these cycles is the ability to quickly test and refine messages in a limited setting before broader implementation. Throughout the study, intervention messages were updated or adapted in response to evolving public health guidelines, testing procedures, and policy recommendations (e.g., priority populations by age group or geographic area, as advised by the Utah Department of Health and Human Services and relevant federal agencies). However, these updates did not alter the fundamental structure of the intervention arms. Participants were randomized to one of two main conditions-Text Messaging (TM) or Text Messaging plus Patient Navigation (TM+PN)-and all participants within a given arm received interventions aligned with their assigned condition. Adaptations occurred within the content and timing of messages or navigation support, but the core components of the interventions remained consistent across participants within each arm. These adaptations were tracked and incorporated into implementation logs but did not constitute distinct intervention arms or conditions. The specific aims are to: 1. Implement and evaluate PHM interventions for increasing the uptake of COVID-19 vaccinations among CHC patients across Utah. Our primary outcome, Uptake-Eligible, is defined as the proportion of patients who receive a COVID-19 vaccination out of those who meet eligibility criteria for vaccination. Our study hypothesis is that patients in the TM+PN cohort will have higher rates of uptake-eligible than those in the TM cohort. 2. Examine implementation effectiveness outcomes, as well as characteristics of both clinics and patients that may influence intervention effects and implementation outcomes.

The study researchers think that a medication called N-acetylcysteine can help fight the COVID-19 virus by boosting a type of cell in your immune system that attacks infections. By helping your immune system fight the virus, the researchers think that the infection will get better, which could allow the patient to be moved out of the critical care unit or go off a ventilator, or prevent them from moving into a critical care unit or going on a ventilator. The US Food and Drug Administration (FDA) has approved N-acetylcysteine to treat the liver side effects resulting from an overdose of the anti-inflammatory medication Tylenol® (acetaminophen). N-acetylcysteine is also used to loosen the thick mucus in the lungs of people with cystic fibrosis or chronic obstructive pulmonary disease (COPD).

The purpose of this study is to see if repeat bacillus Calmette-Guérin (BCG) vaccinations can confer a beneficial immune and metabolic effect on Type 1 diabetes. Published Phase I data on repeat BCG vaccinations in long term diabetics showed specific death of some of the disease causing bad white blood cells and also showed a short and small pancreas effect of restored insulin secretion. In this Phase II study, the investigators will attempt to vaccinate more frequently to see if these desirable effects can be more sustained. Eligible volunteers will either be vaccinated with BCG in a repeat fashion over a period of four years, or receive a placebo treatment. The investigators hypothesize that each BCG vaccination will eliminate more and more of the disease causing white blood cells that could offer relief to the pancreas for increased survival and restoration of insulin secretion from the pancreas. An additional adaptive trial for COVID-19 is also being conducted on these randomized double blinded type 1 diabetic subjects receiving BCG or placebo injections. An expanded study arm has been approved for repeat dosing of BCG in adult Type I diabetes.

Background: - Viral infections are an important cause of illness and death in hospitalized patients as well as outpatients. New strains of viruses may appear and infect both healthy people and those with weak immune systems. A better understanding of these new virus strains (such as SARS-CoV-2, the virus that causes COVID-19) may help to control and prevent these infections. In particular, some viral infections that are less problematic in healthy persons can be life threatening in persons with weak immune systems, and viruses may be able to evolve more rapidly in persons with weak immune systems and therefore develop resistance to existing treatments. Researchers are interested in collecting samples and information from otherwise healthy persons or persons with weak immune systems to study the effects of viruses and their development. Objectives: - To collect samples and data from individuals who have been exposed to or have contracted viral infections. Eligibility: - Individuals of all ages who have been diagnosed with a viral infection are suspected to have a viral infection, or have been in close contact with someone with a suspected or actual viral infection that is of interest to investigators in the Laboratory of Infectious Diseases. - Healthy persons and persons with weak immune systems (immunocompromised individuals) are eligible to participate. Design: - Participants will be pre-screened to determine if they meet the eligibility criteria for the trial. - If eligible, evaluation may include a medical chart review, a history and physical examination, review of clinical reports from outside hospitals and laboratories, and review of tissue biopsies. - Study procedures may include collection of blood, urine, saliva, nasal fluid sampling, throat swabs, stool, and genital swabs. For participants who have specimens collected as part of their medical care (e.g. wound swabs, spinal tap, bronchoscopy, liver biopsy etc.), researchers may use leftover specimens from the clinical laboratory for testing. - Specimens may be collected up to 4 times per week during the first 2 weeks after enrollment, and then as many as 2 times per week for up to 2 years. Some participants may be asked to continue providing specimens if there is concern for relapse or recurrence of the infection. - Treatment is not offered under this study.
