Objective With this prospective natural experiment trial on neurofibromatosis type 2 (NF2) study, we hope to understand the factors leading to tumor progression and neurological disease burden in NF2. Study Population A total of 269 participants, ages 8-75, with a clinical or genetic diagnosis of NF2 will participate in this study. Design Study participants will be evaluated with a thorough physical and neurologic examination upon enrollment. This initial outpatient evaluation will include magnetic resonance imaging with contrast of brain and spine and blood collection for research use. Participants with measurable hearing will have audiology assessment performed. Participants with untreated vestibular schwannomas will have vestibular assessment performed during the initial visit. Genetic studies performed outside will be acceptable as confirmation of NF2 in enrolled patients. If needed to confirm NF2 with genetic studies, or for research purpose, whole genome/whole exome sequencing may be performed on blood obtained from subjects enrolled in this study. All participants will be evaluated by a speech language pathologist. Subjects will be followed as outpatients for up to ten years, during which clinical, and radiologic evaluation will be performed annually. Auditory testing will be performed annually for participants with measurable hearing. Participants with initially untreated vestibular schwannomas will be followed annually with vestibular testing. Speech and swallowing reassessments will be repeated if worsening of speech or swallowing is reported. Blood will be collected at each visit for blood biomarker testing Outcome measures We hope to understand the biologic basis for speech and swallowing dysfunction in patients with NF2. We will study and report the strength of association of MRI findings, clinical assessments cranial nerve deficits and speech/swallowing dysfunction. We hope to identify imaging biomarkers of hearing loss in NF2. We will attempt to discover the mode of peripheral neuropathy in patients with NF2. Lastly, we will attempt to discover previously unknown serum biomarkers associated with high tumor burden in NF2. ...

Background: Throat cancer is a common tumor that can occur in people infected with the human papilloma virus (HPV). Most people with this cancer survive more than 5 years with standard chemotherapy drugs plus radiation. But radiation can cause serious adverse effects. Researchers believe that adding a vaccine (PRGN-2009) to this drug therapy may improve survival without the need for radiation. Objective: To test a study vaccine combined with standard chemotherapy in patients with HPV-associated throat cancers. Eligibility: People aged 18 years and older with newly diagnosed throat cancer associated with HPV. Design: Participants will be screened. They will have a physical exam and blood tests. They will have imaging scans and tests of their heart function and hearing. They will provide a sample of tissue from their tumor. A recent sample may be used; if none is available, a new sample will be taken. All participants will get two common drugs for treating cancer. These drugs are given through a tube attached to a needle inserted into a vein in the arm. Participants will receive these drugs on the first day of three 3-week cycles. Half of the participants will also get the vaccine. PRGN-2009 is injected under the skin in the arm. They will get these shots 4 times: 7 days before the start of the first cycle and on the 11th day of each cycle. Participants will have standard surgery to remove their tumors 3 to 6 weeks after completing the study treatment. They will have follow-up visits 3, 6, 12, and 24 months after their surgery. ...

The Family Investigation of Nephropathy and Diabetes (FIND) is a multicenter study designed to identify genetic determinants of diabetic kidney disease. FIND will be conducted in eleven centers and in many ethnic groups throughout the United States. Two different strategies will be used to localize genes predisposing to kidney disease: a family-based genetic linkage study and a case-control study that utilizes admixture linkage disequilibrium. The center based at the Phoenix office of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK-Phoenix) will conduct family-based linkage studies among American Indian populations in the southwestern United States. Participants (index cases) with diabetes and kidney disease will initially be recruited, and their parents and siblings will also be invited to participate. Genetic material from these participants will be used to genotype markers throughout the genome. Linkage analysis will be conducted to identify particular chromosomal regions containing genes that influence susceptibility to diabetic kidney disease. Linkage analyses will also be used to identify genes influencing traits related to diabetic kidney disease, such as serum creatinine, urinary protein excretion, plasma glucose levels, blood pressure and blood lipid levels. Regions that show evidence for linkage will then be examined in more detail, with both genetic linkage and association studies, to attempt to identify the specific genes that influence diabetic kidney disease, or related traits. The identification of genes that influence susceptibility to diabetic kidney disease will lead to a better understanding of how kidney disease develops. In the long run, this may lead to improved treatment and prevention of diabetic kidney disease.

This study is being done to assess mogamulizumab-associated rash in patients diagnosed with mycosis fungoides or sezary syndrome and treated with standard of care mogamulizumab. One of the most common side effects of mogamulizumab is a rash, currently named mogamulizumab-associated rash (MAR) which can look like MF or SS. However, mogamulizumab-associated rash (MAR) does not indicate failure of mogamulizumab, and may be a sign that the drug is working. If not properly evaluated, mogamulizumab-associated rash (MAR) could be misinterpreted as worsening of mycosis fungoides/sezary syndrome, which could lead doctors to recommend stopping mogamulizumab treatment early. The information learned by doing this research study may help tell the difference between mogamulizumab-associated rash (MAR) (sometimes also called "drug eruption") and worsening of the disease. It may also help to uncover information about the cause of mogamulizumab-associated rash (MAR).

Per the 2021 National Survey on Drug Use and Health administered by the U.S. Department of Health and Human Services, 85% of all American adults consume alcohol. Atrial fibrillation (AF) is the most common arrhythmia, affecting more than 10 million individuals in U.S., comprising 4.5% of the adult population. Although alcohol abstinence clearly reduces AF in heavy drinkers, observational data comparing the health effects of limited consumption versus abstention are conflicting. The Mediterranean diet is one of the few that has demonstrated clear cardiovascular benefits in a randomized study-this diet allows for the consumption of red wine (or high polyphenol/ low alcohol alcohol), generally not more than one drink in 24 hours, with meals, avoiding spirits and binge drinking. The effect of the "Mediterranean drinking pattern" on AF risk compared to alcohol abstinence remains unknown. This single center, randomized, controlled trial aims to compare the effects of a digital health intervention to encourage durable alcohol abstinence versus allowing guideline-adherent moderate alcohol consumption on AF severity. The knowledge gained from this study may be used to determine optimal thresholds for alcohol use among AF patients.

The goal of this clinical trial is to learn if trimethoprim-sulfamethoxazole (TMP-SMX) works to treat invasive infections due to methicillin-resistant Staphylococcus aureus (MRSA) in children. It will also learn about the safety of TMP-SMX in the treatment of children with invasive MRSA infections. The main questions it aims to answer are: -Is TMP-SMX effective at successfully treating children with invasive infections due to MRSA? What are the side effects of TMP-SMX in children taking it for invasive infections due to MRSA? Researchers will compare TMP-SMX to a clindamycin (a commonly prescribed antibiotic for the treatment of MRSA in children) to see if TMP-SMX works better, worse or the same as clindamycin for children with invasive infections due to MRSA. Participants will: Take TMP-SMX or clindamycin for the treatment of their invasive infection due to MRSA. Will follow up with the provider treating their invasive infection at the discretion of the treating provider. Keep a diary of their symptoms and any side effects of the medicine

Researchers are looking for new ways to treat people with proficient mismatch repair (pMMR) endometrial cancer (EC) that is advanced or recurrent. - EC is a type of cancer that starts in the tissues inside the uterus (womb) - pMMR indicates that certain normal proteins are present in the cancer cells - Advanced means the cancer has spread locally or to other parts of the body (metastatic) and cannot be removed with surgery - Recurrent means the cancer came back after surgery Sacituzumab tirumotecan (also known as sac-TMT) and pembrolizumab are the study medicines. Sac-TMT is an antibody drug conjugate (ADC). An ADC attaches to specific targets on cancer cells and delivers treatment to destroy those cells. The goal of this study is to learn if people who receive sac-TMT with pembrolizumab live longer and without the cancer getting worse compared to people who receive pembrolizumab alone.

This study tests whether a medication called droxidopa can help improve blood flow to the kidneys in people with liver cirrhosis who develop kidney problems while in the hospital. When someone with cirrhosis experiences kidney injury, having better blood pressure can help their kidneys recover. Droxidopa is an oral medication that may help raise blood pressure without requiring intensive care or invasive treatments. The study will compare droxidopa to a placebo (inactive pill) in 75 people hospitalized with cirrhosis and kidney injury. Participants will take either droxidopa or placebo pills for 28 days and be monitored for an additional 30 days. Researchers will measure changes in blood pressure and kidney function to determine if droxidopa is effective and safe for these patients. This research could identify a new treatment option for a serious complication of liver disease.

The goal of the proposed study is to understand the reasons for the variability in aerobic exercise (AE) training benefits on the vasculature in middle-age and older (MA/O) adults, including differences between men and women. To achieve this goal, a mechanistic randomized controlled (RCT) will be conducted, in which adults are randomized to 12-weeks intervention of AE or no-exercise Control. Our overall hypothesis is that the exercise response variation in vascular benefits is related to age and sex differences in the biological changes underlying vascular aging and/or the molecular transducers (i.e., circulating molecules) that communicate and coordinate the effects of AE on the vasculature in the periphery and brain. Because this is a mechanistic trial, the overall goal is not a single health-related outcome. Rather, the goal is to advance our understanding of the molecular signals and pathways underlying the systemic and local effects of AE on vascular health that may explain the variability in AE responses with age and sex. This knowledge will allow for the development of personalized age- and sex-specific AE recommendations, and/or provide insights into molecular targets that can be manipulated to enhance and/or mimic exercise in non-responders or in persons unable to exercise.
