This study compares opioid-free anesthesia to standard opioid-based anesthesia in 600 adults undergoing urological abdominal surgery. The goal is to see if avoiding opioids during surgery reduces the need for painkillers afterward and lowers side effects like nausea. Patients wil…

This study looks at inflammation markers in the blood of women with PCOS, with or without insulin resistance, and compares them to women without PCOS. The goal is to understand how inflammation relates to metabolic problems in PCOS. Participants will have blood tests but no treat…

This study is measuring three proteins (kisspeptin, ghrelin, and zonulin) in the blood of women with and without PCOS to see if they can serve as early warning signs of insulin resistance. Researchers will compare levels among three groups: women with PCOS and insulin resistance,…

This study looks at three hormones (leptin, resistin, omentin-1) in women with PCOS, with or without insulin resistance, and compares them to women without PCOS. The goal is to better understand how these hormones relate to metabolic health. No treatments or interventions are giv…
