This study observed how well a new type of heart stent works in everyday patients. The Ultimaster stent is coated with a medicine and a polymer that dissolves over 3-4 months, which may reduce long-term inflammation and clotting risks compared to older stents. Researchers followe…

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 observed 200 patients with complex coronary artery disease who received a specific type of drug-coated stent. The goal was to see how safe and effective this stent is over the long term in patients at high risk for heart attacks or other heart-related problems. Researc…

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 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 tested whether a new skin booster made from processed human tissue, when mixed with a standard hyaluronic acid filler, works better than the standard filler alone. Researchers compared the two treatments by injecting one into each cheek of 20 participants over three mo…

This study tested whether a drug called iloprost, given as an inhaled mist, could help maintain better oxygen levels in the blood of obese patients during a specific type of lung surgery. During this surgery, called one-lung ventilation, patients breathe with only one lung, which…

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 aimed to understand if a hormone called erythroferron helps patients recover from low blood counts (anemia) after heart valve surgery. Researchers measured this hormone and blood levels in 150 patients having elective surgery. The goal was to see if higher hormone leve…

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…
