This study compares two oral treatments for trichomonas, a common sexually transmitted infection. About 1,200 women and men with a positive test will receive either a single dose of secnidazole or multiple doses of metronidazole over several days. The goal is to see which approac…

This study tests a health coaching program called STAR-MAP to help older adults (age 40+) with high blood pressure take their medication regularly. About 402 participants with uncontrolled blood pressure and low medication adherence will be recruited through a Louisiana health in…

This study tests a weight loss program for 522 low-income adults with obesity in Louisiana. Participants receive health coaching, digital self-monitoring tools, and group support to find community wellness resources. The goal is to see if this approach leads to greater weight los…

This study tests whether using very little contrast dye (less than 20cc) during coronary angiography is safer for patients who already have acute kidney injury. Researchers will compare immediate angiography with delayed angiography to see if ultra-low contrast reduces the risk o…

This study tests whether continuous glucose monitors (CGMs) can improve blood sugar control in underserved people with type 2 diabetes who are uninsured or on Medicaid. Fifty participants will wear a CGM replaced every 14 days for 6 months. The goal is to see if this technology h…

This study provides free testing for chlamydia, gonorrhea, syphilis, and HIV to Black youth aged 15-26 in New Orleans. Those who test positive can get treatment at no cost and are encouraged to bring their partners. The goal is to reduce STI rates and health disparities in this c…

This study tests a medicated foam (roflumilast) applied to the skin for hidradenitis suppurativa, a painful inflammatory condition. Ten adults will use the foam alone or with their usual treatments for 4 months. Researchers will check if it improves symptoms and analyze skin gene…

This study looks at whether kidney transplants from HIV-positive donors are safe and effective for HIV-positive recipients. Researchers will follow 30 adults with HIV and end-stage kidney disease who receive a kidney from an HIV-positive donor. The goal is to learn more about pat…

This study tests whether a 3-month cooking class focused on the Mediterranean diet can improve heart health and blood sugar in racially diverse seniors aged 55 and older. Participants will learn to cook healthy meals in a community kitchen, while researchers measure changes in bl…

This study tests two ways to reduce cockroach allergens in homes of children with asthma in New Orleans. One group gets a simple cockroach bait, the other gets a tailored plan including education, mattress covers, and air purifiers. Over 12 months, researchers will track asthma s…

This study is testing whether a simple, non-invasive sensor called photoplethysmography (PPG) — already found in many smartwatches — can accurately predict how well the heart pumps blood (ejection fraction) and other heart health measures. Researchers will have 500 adults wear a …

This study is testing a new blood test called CRISPR-TB to diagnose tuberculosis (TB) in children more accurately. Current tests often miss TB in kids because they have fewer bacteria. The study will enroll 1,220 children in Bolivia to see if this test can detect TB better than s…

This study tests a program called M-O-M-S on the Bayou, which pairs pregnant women with experienced mothers for support and classes. The goal is to reduce anxiety and depression in women living in areas hit by natural disasters. Researchers will recruit 240 pregnant women and tra…

This pilot study at Tulane University is testing whether obstructive sleep apnea (OSA) can cause scarring (fibrosis) in the heart's upper chambers, even in people without atrial fibrillation. Researchers will use a special MRI with contrast dye to measure scarring in 60 adults wi…

This study looks at whether scarring (fibrosis) in the heart's upper chambers can predict who will develop an irregular heartbeat after heart surgery. Researchers will track 50 adults aged 40+ with no prior irregular heartbeat who are scheduled for heart surgery. The goal is to s…

This study collects blood and nasal secretions from up to 2,000 people with COVID-19 to learn why some get very sick while others recover easily. Researchers will also track long-term symptoms like fatigue and brain fog. No treatments are tested—the goal is to gather data to guid…

This study will have up to 10,000 adults wear a smartwatch for one year to collect health data like heart rate and activity. Participants will also answer questions through a phone app. The goal is to see if smartwatch data can help doctors spot heart problems earlier. No drugs o…

This pilot study aims to see if certain blood markers that indicate clotting increase when atrial fibrillation (AFib) is more active. Researchers will take blood samples from 20 adults before, during, and up to 90 days after a catheter ablation procedure. The goal is to better un…
