This study followed 204 patients with blocked heart arteries who received a new type of stent called Ultimaster. The stent is coated with a medicine to prevent re-narrowing and has a special coating that dissolves over 3-4 months, which researchers hope will reduce long-term risk…

This study observed the long-term safety and effectiveness of a new type of drug-coated heart stent in patients with severe coronary artery disease. The stent slowly releases medication to help keep the artery open after a procedure to clear a blockage. Researchers followed 200 h…

This study tested a new way to perform a common heart artery procedure (PCI) by accessing the artery through a spot on the wrist instead of the groin. It used a specially designed thinner tube to see if this approach is safe and effective, particularly for reducing bleeding and o…

This study tested whether aiming for very low 'bad' cholesterol (LDL) levels is better than standard low levels for people with heart disease. Over 3,000 participants were randomly assigned to either a very low target or a standard target, using either a single cholesterol drug o…

This study tested whether a medication called fexuprazan could prevent or control gastritis (stomach lining irritation) in adults needing long-term steroid treatment for respiratory diseases. It compared fexuprazan against an existing stomach-protecting drug (lansoprazole) over f…

This study tested whether wearing a heart monitor for 8 days finds more cases of atrial fibrillation (a dangerous irregular heartbeat) than wearing it for just 1 day. It involved 1,000 adults aged 75+ or at high risk for stroke who had symptoms like palpitations or dizziness. Res…

This study tested whether a new skin booster treatment (called phADM mixed with hyaluronic acid) works better than hyaluronic acid alone to improve facial wrinkles, skin texture, and lifting. Researchers compared the two treatments by injecting one into each cheek of 20 adult par…

This study tested whether a drug called iloprost, inhaled during surgery, could improve oxygen levels in the blood of obese patients undergoing lung cancer surgery. During this type of surgery, one lung is temporarily taken 'offline' for the operation, which can make it harder fo…

This study tested whether a single session of a radiofrequency skin treatment could improve jawline definition and facial contouring. Researchers followed 22 women aged 38-50 for 8 weeks after their treatment. They measured changes in jawline position and facial volume using 3D i…

This study tested whether a non-invasive brain stimulation device, used at home, could help reduce symptoms of depression. Nearly 200 adults with mild to moderate depression used the device on themselves for six weeks. Researchers measured changes in depression, anxiety, and thin…

This study aimed to understand if a hormone called erythroferron helps patients recover their red blood cell levels after heart valve surgery. Researchers measured this hormone and hemoglobin levels in 150 adults undergoing elective surgery. The goal was to learn how the body nat…

This study aimed to see if a new approach to accessing heart arteries through the left wrist exposes doctors to less radiation than the standard right wrist approach. Over 1,000 patients scheduled for heart imaging or stenting were randomly assigned to one of the two methods. Res…

This study aimed to find biological markers in the blood and tumors of lung cancer patients that could predict who would benefit from the immunotherapy drug atezolizumab. It involved 100 patients with advanced non-small cell lung cancer whose disease had progressed after prior tr…

This study looked at whether a patient's vitamin D level before heart bypass surgery is linked to how well their blood recovers afterward. Researchers followed 135 patients to see if vitamin D influences hormones that control iron and red blood cell production. The goal was to ga…
