Long COVID is defined by a range of symptoms affecting multiple organs that persist for more than three months following an acute SARS-CoV-2 infection. Approximately 7% of individuals who recover from SARS-Cov-2 infection develop Long COVID. Long COVID Postural Orthostatic Tachycardia Syndrome (LCPOTS) symptoms include fatigue, exercise intolerance, orthostatic intolerance, syncope, and heightened orthostatic tachycardia. Research has found that decreased parasympathetic activity in LCPOTS increases the production of highly immunogenic neoantigens Isolevuglandins (IsoLG-adducts). IsoLG-adducts induce formation of circulating monocyte/T cell complexes(doublets) leading to the persistent and unresolved immune response that continues after the initial infection. The purpose of the this research, is to study the effects of 2-hydroxybenzylamine (2-HOBA), an Iso-LG-adduct scavenger, its effects in immune markers and compare it with Placebo

The goal of this study is to compare the abuse potential of low-dose equianalgesic buccal buprenorphine to a commonly used full mu opioid receptor (MOR) agonist in a highly controlled experimental setting. This is a translational study in which healthy participants are phenotyped for psychosocial and Opioid-Use-Disorder-risk-related metrics. In a within-subjects crossover design, 60 participants will receive a standard postoperative oral oxycodone dose (10 mg), placebo, and 3 different doses of buccal buprenorphine across 5 separate sessions. Quantitative Sensory Testing (QST) will be used to evaluate alterations in pain responsiveness relative to placebo across buprenorphine doses and oxycodone, and will compare abuse potential (indexed by the standard FDA drug liking metric) following equianalgesic doses of the two drugs.

This study aims to understand the heart and blood sugar health benefits of using an adjunctive therapy to lower high insulin levels in people with type 1 diabetes. The investigators will also look at people with a specific type of diabetes called Glucokinase-Maturity Onset Diabetes of the Young (GCK-MODY) and those without diabetes to help interpret the results. The investigators will use a medication that helps the body get rid of sugar, called and SGLT2 inhibitor, with the goal to reduce the body's insulin requirements. The investigators believe this could lead to better heart and blood sugar health, including a better response to insulin and more available nitric oxide, a gas that helps blood vessels function well. The investigators will compare heart and blood sugar health risk factors in participants with type 1 diabetes, participants with Glucokinase-Maturity Onset Diabetes of the Young (GCK-MODY), and non-diabetic healthy volunteers under two conditions: high insulin levels typical of type 1 diabetes and normal insulin levels typical of the other two groups.

This will be a follow-up study to the "Comparison of High Dose vs. Standard Dose Influenza Vaccine in Lung Allograft Recipient" study (DMID Protocol Number 22-0014) at Vanderbilt University Medical Center. Lung transplantation is a life-saving therapy for patients with advanced lung disease, and is also associated with an improvement in quality of life. However, due to the need for life-long immunosuppression to prevent acute cellular rejection and chronic lung allograft dysfunction ("chronic rejection"), lung transplant recipients are at risk for developing major infections. In fact, one-year survival is 85%, with infection being the leading cause of death within the first year post-transplant. We will conduct a follow-up phase II, randomized, double-blind trial to assess the impact of subsequent administration of two doses of HD-IIV compared to two doses of SD-IIV among lung recipients during the early post-transplant period. Demonstration of improved immunogenicity from two doses of HD-IIV over consecutive influenza seasons would provide potential broad benefit in reducing influenza disease and its associated complications in lung transplant recipients. Moreover, studying vaccine immunogenicity and safety in the same participants over consecutive years can provide insight into the influence of immunosuppression levels and allograft aging on vaccine-mediated immune modulation. This proposed study design will contribute significantly to influenza vaccination guidance and policy for the highly vulnerable lung transplant population. This proposed study is designed to address several key knowledge gaps in vaccine-mediated protection of lung transplant recipients against influenza: - Is there increased immunogenicity with administration of one or two doses of HD-IIV or SD-IIV in the subsequent season compared to two doses of HD-IIV or SD-IIV in the first season? - What is the durability of the humoral and cellular immune response between influenza seasons and does two doses of HD-IIV or SD-IIV sustain higher HAI titers compared to two doses of HD-IIV or SD-IIV in the first season? - What is the impact of maintenance immunosuppression levels on influenza vaccine immunogenicity within the same participant? - Will the optimal immunogenic vaccination strategy be associated with an acceptable long-term safety profile over successive influenza seasons, including injection-site and systemic reactions, allosensitization, and organ rejection?

This phase II trial tests how well pB1-11 and human papillomavirus tumor antigen (TA-HPV) vaccines in combination with pembrolizumab work in treating patients with oropharyngeal cancer that has come back (recurrent) or that has spread from where it first started (primary site) to other places in the body (metastatic) and that is PD-L1 and human papillomavirus (HPV) positive. Oropharyngeal cancer is a type of head and neck cancer involving structures in the back of the throat (the oropharynx), such as the non-bony back roof of the mouth (soft palate), sides and back wall of the throat, tonsils, and back third of the tongue. Scientists have found that some strains or types of a virus called HPV can cause oropharyngeal cancer. pBI-11 is a circular deoxyribonucleic acid (DNA) (plasmid) vaccine that promotes antibody, cytotoxic T cell, and protective immune responses. TA-HPV is an investigational recombinant vaccina virus derived from a strain of the vaccina virus which was widely used for smallpox vaccination. Vaccination with this TA-HPV vaccine may stimulate the immune system to mount a cytotoxic T cell response against tumor cells positive for HPV, resulting in decreased tumor growth. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread by inhibiting the PD-1 receptor. These investigational vaccines could cause or enhance an immune response in the body against HPV, during which time the activity of pembrolizumab against oropharyngeal cancer associated with HPV may be strengthened. These drugs in combination may be more effective in increasing the ability of the immune system to fight oropharyngeal cancer than pembrolizumab alone.

Rhabdomyosarcoma is a type of cancer that occurs in the soft tissues in the body. This phase III trial aims to maintain excellent outcomes in patients with very low risk rhabdomyosarcoma (VLR-RMS) while decreasing the burden of therapy using treatment with 24 weeks of vincristine and dactinomycin (VA) and examines the use of centralized molecular risk stratification in the treatment of rhabdomyosarcoma. Another aim of the study it to find out how well patients with low risk rhabdomyosarcoma (LR-RMS) respond to standard chemotherapy when patients with VLR-RMS and patients who have rhabdomyosarcoma with DNA mutations get separate treatment. Finally, this study examines the effect of therapy intensification in patients who have RMS cancer with DNA mutations to see if their outcomes can be improved.

This phase I trial evaluates the safety and effectiveness of using two imaging techniques, indium In 111 panitumumab (111In-panitumumab) with single photon emission computed tomography (SPECT)/computed tomography (CT) and panitumumab-IRDye800 fluorescence imaging during surgery (intraoperative), to detect disease in patients with head and neck cancer. 111In-panitumumab is an imaging agent made of a monoclonal antibody that has been labeled with a radioactive molecule called indium In 111. The agent targets and binds to receptors on tumor cells. This allows the cells to be visualized and assessed with SPECT/CT imaging techniques. SPECT is special type of CT scan in which a small amount of a radioactive drug is injected into a vein and a scanner is used to make detailed images of areas inside the body where the radioactive material is taken up by the cells. CT is an imaging technique for examining structures within the body by scanning them with x-rays and using a computer to construct a series of cross-sectional scans along a single axis. Panitumumab-IRDye800 is an imaging agent composed of panitumumab, a monoclonal antibody, linked to a fluorescent dye called IRDye800. Upon administration, panitumumab-IRDye800 targets and binds to receptors on tumor cells. This allows the tumor cells to be detected using fluorescence imaging during surgery. Adding 111In-panitumumab SPECT/CT imaging to intraoperative panitumumab-IRDye800 fluorescence imaging may be more effective at detecting disease in patients with head and neck cancer.

Researchers are looking for new ways to treat ovarian cancer (OC). Current treatment for OC may start with surgery to remove as much of the cancer as possible. After surgery, people may receive chemotherapy. After chemotherapy, standard care options may include: - Maintenance treatment, which is used after another therapy to keep the cancer from growing, spreading, or coming back. Bevacizumab is a targeted therapy used as standard maintenance treatment. Targeted therapy works to control how specific types of cancer cells grow and spread. - Observation, which is watching to see if cancer grows or worsens The study medicine, sacituzumab tirumotecan (also called sac-TMT), is a targeted therapy. The goal of this study is to learn if people who receive sac-TMT maintenance treatment with or without bevacizumab live longer without the cancer getting worse than people who receive standard care.
