NCT04163614
Kidney failure has been recognized as one of the most costly chronic conditions among United States Veterans. Approximately 13,000 Veterans develop kidney failure each year, and most require hemodialysis initiation. Hemodialysis patients suffer significantly increased risk of death and hospitalizations, and excessive body fluid is a major cause of this. While empiric aggressive fluid removal during dialysis is one approach to limit fluid overload, this can cause dangerous decreases in blood pressure during dialysis that independently contribute to the high death rate. In this study, I aim to test a new strategy that prescribes fluid removal based on a patient's recent blood pressure patterns during dialysis. This clinical trial will compare my strategy to standard care and assess the outcomes of overall blood pressure change between dialysis treatments in addition to the number of times the blood pressure becomes dangerously low during dialysis. Another aim is to determine how differences in the structure and function of the heart influence blood pressure during dialysis.
NCT07298759
The purpose of this clinical trial is to evaluate the effect of hydroxytyrosol 10 mg/day administered for 4 weeks in pregnant individuals with hypertension. This study will assess whether hydroxytyrosol increases serum superoxide dismutase levels, reduces uterine artery Doppler pulsatility and resistance indices, and improves brachial artery flow-mediated dilation. Participants will be randomly assigned to receive either hydroxytyrosol or a matching placebo. Both products will be visually identical to ensure blinding. Participants will take two capsules daily for 4 weeks and attend two study visits for assessments and follow-up.
