The goal of this pilot study is to assess the feasibility and impact of using sodium citrate nasal spray as an adjunct to olfactory retraining in participants with long-term post-COVID-19 olfactory dysfunction. The main questions it aims to answer are: - Is sodium citrate nasal spray in addition to smell retraining feasible for participants to use in terms of participant need/desire, adherence, and adverse events? - Does sodium citrate nasal spray in addition to smell retraining further improve smell as compared to normal saline spray and smell retraining? Participants will: - Provide consent for enrollment. - Undergo smell testing via Sniffin' Sticks. - Use a nasal spray (either sodium citrate or normal saline) followed by olfactory retraining twice a day for 12 weeks. - Return for follow-up Sniffin' Sticks testing. Researchers will compare the sodium citrate group and the normal saline group to determine differences in smell improvement.

This study will determine the effectiveness of a vaccine communication mobile health app on parental decisions to vaccinate their children against coronavirus disease 2019 (COVID-19). The hypothesis is that unvaccinated children of caregivers assigned to the Vaccine Uptake app will be more likely to achieve COVID-19 vaccine series completion than those children whose caregivers are assigned to the General Health app.

The human immune system is designed to protect individuals from external sources of infection and internal cell mutation. It works effectively and efficiently until inflammation disturbs its functioning. Once compromised by inflammation, the immune system loses its capacity to recognize antigens and dependably defend the body against disease and illness. When COVID-19 invades humans, it causes an immune-storm (cytokine-storm) that can directly damage the organ(s), leading to death. The virus is an antigen - a trigger - but it is not the actual reason that causes organ failure and death; instead, it is the body's over immune reaction that is the cause. In attempting to protect the body, the immune system overreacts to the antigen, which includes the infected cells, which causes a cytokine-storm, and the subsequent and rapid shut down of the infected individual's organ(s)' structure, leaving the body without sufficient strength or time to fight back. When the medical herbs join the body, it can slow down the immune reaction. Medical herbs benefit the physical body; they protect the cells and organism structure and mediate the immune response, allowing the T cells to kill the virus (mutated or not) internally. Such success has been achieved by the All Natural Medicine Clinic during pre-clinical trials. This clinical study's goal is to demonstrate that the immune system can be rebuilt and retrained, using natural medicine (i.e., medical herbs), to kill the virus without causing the immune storm, and to explore the mechanism by which these medical herbs, which have been used for thousands of years for healing, achieve results.

Patient are being asked to provide respiratory and blood samples for a clinical research study because the patients have a virus called the novel coronavirus, or SARS-CoV-2, that causes the disease known as Covid-19. Investigators do not know a lot about this virus, including all the ways it travels from person to person. Investigators also do not know if a person will get sick or not from the virus after being in close contact with someone who has the virus. Because of this, investigators are performing research on the virus found in respiratory secretions to get more information on how investigators can best detect and treat this new virus in the future. Primary Objective - To determine the clinical characteristics and outcomes of Covid-19 in children. - To characterize the clinical risk factors of Covid-19 in children.. Secondary Objectives - To characterize the immunological risk factors and serologic response to SARS-CoV-2 infection in children.- To evaluate the duration of viral shedding in children. - To evaluate the duration of SARS-CoV-2 viral shedding in children.

This phase II expanded access trial will study how well tocilizumab works in reducing the serious symptoms including pneumonitis (severe acute respiratory distress) in patients with cancer and COVID-19. COVID-19 is caused by the SARS-CoV-2 virus. COVID-19 can be associated with an inflammatory response by the immune system which may also cause symptoms of COVID-19 to worsen. This inflammation may be called "cytokine storm," which can cause widespread problems in the body. Tocilizumab is a medicine designed to block the action of a protein called interleukin-6 (IL-6) that is involved with the immune system and is known to be a key factor for problems with excessive inflammation. Tocilizumab is effective in treating "cytokine storm" from a type of cancer immunotherapy and may be effective in reducing the inflammatory response and "cytokine storm" seen in severe COVID-19 disease. Treating the inflammation may help to reduce symptoms, improve the ability to breathe without a breathing machine (ventilator), and prevent patients from having more complications.

This study will be conducted as a prospective cohort study, enrolling all eligible women in their first trimester of pregnancy during a baseline visit during week 6-13 of pregnancy at Government Medical College Hospital, Nagpur. The Hospital provides primary, secondary, and tertiary care and the obstetric department delivers about 10,000 babies a year. The hypothesis is that co-infection of other respiratory viruses (ORV), particularly COVID-19 and Influenza increases the risk of adverse pregnancy outcomes in mothers and babies and could address the current standard of care in India to not vaccinate pregnant women during pregnancy, by either encouraging vaccination against both viruses before planning a pregnancy or during pregnancy based on global data supporting the safety of this strategy.

The long-term objective of SCALE-UP II is to increase the reach, uptake, and sustainability of COVID-19 testing among underserved populations. Through RADx-UP Phase I funding (SCALE-UP Utah), the team has established population health management (PHM) interventions that have been used since Feb 2021 to increase the uptake of COVID-19 testing and vaccination among community health center patients. Interventions are based on a PHM approach that uses widely available technology (i.e. cell phones and text messaging). SCALE-UP II will both build on SCALE-UP Utah PHM interventions and investigate novel resource conservation approaches (i.e., Request-Patient Navigation vs. No Patient Navigation and text messaging vs. conversational agent). SCALE-UP II builds on long standing partnerships among the University of Utah Clinical and Translational Science Institute (UofU CTSI), Association for Utah Community Health (AUCH), CHCs, and the Utah Department of Health(UDOH). CTSI and SCALE-UP II investigators are leading several COVID-19 initiatives that drive public health response and state government policies in Utah. Thus, the UofU team is uniquely positioned to lead this project.

This project will address key testing challenges in Utah schools by building on collaborations with public school districts, private schools, charter schools and with Utah Department of Health on coronavirus disease (COVID-19) testing and existing infrastructure. The study team will work closely with schools and the Utah public health system to implement and test a shovel-ready and scalable health information technology approach that delivers automated text messages (TM) to students' parents around COVID-19 testing. In addition, some parents will receive a health navigator (HN) follow-up to ensure that tests are completed. Families will be offered the recently FDA-approved in-home serial testing approach if accessing in-person testing is a challenge. While this project is focused on COVID-19 testing, in the case that the COVID-19 vaccination becomes more relevant or is the priority of the school, the study team is able to tailor the intervention to focus on the vaccine as well. The outcomes in this study utilized parent/student reported data. Staff data were also collected but will not be reflected in primary outcome analyses.
