This study tests whether a special software (HPI and AFM) can help doctors prevent low blood pressure in adults having surgery with general anesthesia. About 100 participants will be randomly assigned to either standard care or care guided by the software. The goal is to see if t…

This study tests a procedure that uses heat (radiofrequency ablation) and bone stabilization to treat spine tumors that have spread from other cancers. About 16 people with one to three active spine tumors will receive the treatment. The main goal is to see if the tumors become l…

This study is testing whether a procedure that combines a simple stitch to lift hemorrhoid tissue with a laser treatment can effectively relieve pain, bleeding, and prolapse in adults with moderate-to-severe hemorrhoids. About 100 participants will receive the combined treatment …

This study compares two surgical methods to treat peri-implantitis, a gum infection around dental implants. One method smooths the implant surface, while the other uses an air-abrasive device to clean it. The goal is to see which approach better controls infection and preserves t…

This study tests whether adding a sugar solution (dextrose) to numbing injections around knee nerves provides better pain relief than numbing medicine alone for people with chronic knee osteoarthritis. Sixty adults with knee arthritis will receive a series of three injections tar…

This study tests whether injecting a sugar solution (prolotherapy) into acupuncture points can reduce chronic low back pain better than a standard numbing injection alone. Sixty adults with long-term back pain will receive up to 15 injections over three sessions. Researchers will…

This study watches how doctors decide on treatments for people with early-stage, hormone-sensitive breast cancer. It includes up to 2,000 participants and follows them for 10 years to see how well they do. The goal is to learn whether a test called EndoPredict helps guide better …

This study looks at how two weight-loss medications, tirzepatide and liraglutide, affect bone strength and body composition in adults with severe obesity (BMI 40 or higher). Researchers will track 72 participants for 6 months, measuring bone turnover markers and body changes. The…

This study looks at five different ways to treat gum disease without surgery. The goal is to see how each method affects inflammation throughout the body and the amount of bacteria that enter the bloodstream during treatment. Researchers will measure blood markers and bacteria le…

This study follows 100 adults who have surgery for a perianal fistula (an infected tunnel near the anus). Researchers will check healing, return of the fistula, and how surgery affects bowel control and quality of life over one year. The goal is to give doctors better information…

This study looks at whether a blood test marker called Monocyte Distribution Width (MDW) can help predict serious complications and survival in older adults with hip fractures. About 100 patients aged 65 and older will be followed after surgery to track infections, hospital stays…

This study looks at using the ulnar artery in the wrist for heart procedures when the usual radial artery is blocked. About 127 adults with a blocked radial artery will be observed to see if using the ulnar artery is safe and how it affects hand strength and function. The goal is…

This study compares two common anesthetic gases, sevoflurane and desflurane, to see which one helps keep lungs working better during robotic abdominal surgery. About 50 adults having elective robotic abdominal surgery will take part. The main goal is to measure airway pressure, a…

This study compares two ways to remove infection from the tip of a tooth root: using a standard rotary bur or a piezoelectric device. Researchers want to see which method leads to better bone healing. About 130 adults who need this surgery will be followed for at least a year wit…
