To evaluate the safety and performance of the Xeltis hemodialysis access graft in subjects older than 18 years with end stage renal disease (ESRD) and possessing an estimated glomerular filtration rate (eGFR) less than 20 ml/min.

The purpose of this research is to look at the safety and tolerabilty of an experimental study drug called AZD4144 and its effect on Sepsis-Associated Acute Kidney Injury (SA-AKI). The main goal of this research is to compare specific kidney function measurements between those participants receiving AZD4144 and those receiving the placebo.

The purpose of this research study is to evaluate the safety and effectiveness of a
physician-modified endograft (tubular medical device used to reinforce weakened or damaged blood vessels) for repairing serious diseases of the aorta (largest artery in the human body, responsible for blood from the heart to the rest of the body). This device is considered investigational, and this research study received an Investigational Device Exemption (IDE) from the FDA.

This study is trying to find out whether early repair of small Abdominal Aortic Aneurysms (AAAs) in women improves health outcomes compared to routine monitoring. An AAA occurs when a section of the aorta in the abdomen weakens and bulges outward, resembling a balloon. This condition is serious because if the aneurysm ruptures, it can cause severe internal bleeding and can be fatal. This question is important because women with small AAAs may have a higher risk of rupture than men, and doctors are not yet sure whether early repair is better than standard monitoring. Surgical repair is the elective standard of care for aneurysms above 5.5cm in size. In our study we are evaluating if earlier repair (between 4.0- 5.4 cm) might be beneficial to women with abdominal aneurysms, but it is important to note that surgical repair involves risks and could lead to other complications, including death. These risks are discussed later in this form. There is also the possibility that you may need additional procedures, including open surgery.

Adult subjects with rectal cancer undergoing sphincter sparing resection and colonic anastomosis. Post-operative follow-up will occur at 7-10 days, 30 days, 90 days, 180 days, and 270 days.

This is a prospective, multicenter, observational study designed to evaluate the clinical utility and prognostic relevance of serial TRAC and T-ID monitoring in kidney transplant recipients under routine clinical care.

The purpose of this research is to evaluate the safety and effectiveness of the EchoMark/EchoSure System for AVF (arteriovenous fistula) for assessing AV fistula maturation when used under a protocol of biweekly use as compared to the standard of care follow-up. Target subject population are subjects presenting with Stage 5 Chronic Kidney Disease (CKD5) or End Stage Renal Disease (ESRD) undergoing upper arm autologous arteriovenous fistula creation for hemodialysis access who are on dialysis or will imminently require dialysis (GFR <10).
