Hyperparathyroidism

This study looks at whether injecting special stem-like cells called Muse cells directly into the ovaries can help women aged 28 to 70 who are in perimenopause. The cells may repair tissue, reduce inflammation, and improve hormone balance. Researchers will track safety, hormone l…

This Phase II trial tests whether combining lenvatinib and everolimus can shrink or slow advanced carcinoid tumors that cannot be removed by surgery. The study enrolls 36 adults with confirmed unresectable carcinoid tumors. Both drugs are taken orally and work by blocking enzymes…

This study tests whether eating wild blueberry powder every day can lower blood pressure and improve blood vessel health in middle-aged and older men and postmenopausal women with slightly high blood pressure. Researchers will measure artery function and stiffness over time. The …

This study offers voluntary screening for newborns in North Carolina to detect a wide range of rare health conditions early. Using a small blood sample already collected at birth, the program tests for dozens of disorders, including spinal muscular atrophy, cystic fibrosis, and m…

This study is testing whether whole body MRI scans can help find cancers early in children and adults with Li-Fraumeni syndrome, a genetic condition that greatly raises cancer risk. About 150 participants will receive annual whole body MRI scans for four years to see if they keep…

This study tests a small device that delivers mild electrical stimulation to the perineum (the area between the scrotum and anus) to help men who leak urine after prostate removal surgery. Thirty men who are scheduled for robotic prostate surgery and already use at least one pad …

This study tests a 6-week group program called Working Out Dads (WOD) to see if it helps reduce mental health struggles in fathers of children aged 0-4. About 293 dads with mild to moderate distress will either join the WOD peer-support group or receive usual care. The goal is to…

This study tests whether placing a placental-based allograft called Amnioeffect on the surgical wound improves scar appearance, pain, and swallowing after thyroid or parathyroid surgery. About 334 adults will be enrolled, with half receiving the graft and half getting standard ca…

This study compares two methods of monitoring the nerve that controls the vocal cords during thyroid and parathyroid surgery. The standard method uses a breathing tube with electrodes, while the new method uses tiny needles placed directly into the voice box cartilage. Researcher…

This study looks at whether removing overactive parathyroid glands (parathyroidectomy) can improve blood sugar control in people who also have type 2 diabetes. Researchers will compare 80 patients who have surgery with those who do not, measuring changes in blood sugar and bone h…

This study looks at whether a 25-minute hydration education session plus a self-assessment worksheet can help wildland firefighters and other active people drink more fluids and stay hydrated. About 38 participants who are underhydrated will be split into two groups: one gets the…

This study evaluates a program that aims to improve diets by making healthy foods like fish, chicken, and eggs more available and affordable for low-income households in Mozambique. Researchers will survey over 5,000 men and women to see if the program increases how often they ea…

This study gathers health questionnaires from up to 1,500 people with multiple endocrine neoplasia (MEN1 or MEN2) and their close relatives. The goal is to build a database that helps researchers better understand these rare inherited conditions. No new treatments or procedures a…

This study looks at how diet and exercise affect the epigenome—chemical marks on DNA—in sperm of overweight Hispanic men. Researchers will compare sperm from 20 healthy active men and 80 obese inactive men before and after a 12-week program of diet, exercise, or both. They will a…

This study looks at 475 people on hemodialysis to find better markers for bone disease and blood vessel hardening. Researchers are checking if new markers can predict heart attacks, strokes, and death better than current tests. The goal is to improve monitoring and care for dialy…

This study follows 1,800 adults with reduced kidney function (not on dialysis) to see how nutrition and lifestyle affect their health. Researchers will track changes in kidney function, heart health, bone health, and thinking skills over time. The goal is to find better ways to m…

This study watches 200 people with lung, gut, or hormone diseases over time using special brain scans (PET). It aims to see how these diseases change brain activity and whether those changes can predict tumor return, spread, or survival. No new treatment is tested—just observatio…
