This study tests whether giving a drug called noradrenaline during non-cardiac surgery can prevent episodes of very low blood pressure better than standard care. About 750 adults aged 45 and older having surgery lasting at least one hour will take part. The goal is to see if this…

This study compares two weight-loss surgeries for people with severe obesity and acid reflux (GERD). About 560 participants will be randomly assigned to either a newer procedure (Nissen-Sleeve) or the standard Roux-en-Y gastric bypass. The main goal is to see if the newer surgery…

This study looks at inflammatory substances in the blood of women with PCOS, with or without insulin resistance, compared to women without PCOS. Researchers want to see if certain inflammation markers are linked to metabolic problems. No treatments are given; the goal is to bette…

This study looks at how many women develop post-traumatic stress disorder (PTSD) symptoms after an ectopic pregnancy. Researchers will survey 200 women to measure their emotional distress and recovery. The goal is to better identify those who might need early psychological help.

This study looks at three proteins (kisspeptin, ghrelin, zonulin) in the blood of women with PCOS to see if they can serve as early warning signs for insulin resistance. Researchers will compare protein levels among women with PCOS and insulin resistance, women with PCOS but no i…

This study looks at three hormones made by fat tissue (leptin, resistin, and omentin-1) in women with PCOS, with or without insulin resistance, compared to women without PCOS. Researchers want to see if these hormones are linked to metabolic problems. About 300 women aged 18-45 w…

This study looks at immune cells in the womb lining and blood of 50 women with normal or reduced fertility (including those with unexplained infertility or recurrent miscarriage). Researchers want to see if differences in these cells help explain why some women struggle to get pr…

This study uses questionnaires to measure how many women develop post-traumatic stress disorder (PTSD) symptoms after an early miscarriage (up to 14 weeks of pregnancy). Researchers will enroll 200 women and track their emotional recovery over time. The goal is to better identify…
