NCT05785871
The purpose of this research study is to measure cerebrospinal fluid (CSF) clearance in subjects with and without high blood pressure. CSF cushions the brain from impact and carries waste products from the brain to the bloodstream. This process is known as clearance. Impaired removal of proteins from the aging brain causes their buildup and may contribute to an increased risk for Alzheimer's disease. It is also suspected that clearance may be related to the health of vessels carrying the blood throughout the brain. It is known that high blood pressure damages blood vessels and thus may impair clearance. In this project we will examine if having high blood pressure is related to impaired brain clearance and whether treating high blood pressure improves clearance and reduces buildup of Alzheimer's disease-related proteins. Participants will be asked to undergo a medical examination, testing of memory, brain imaging (both magnetic resonance and positron emission tomography, and spinal tap at the beginning of the study and 1 -2 years later.
NCT03480217
The goal of this study is to use a cluster-randomized design (1:1 ratio) among 8 primary care clinics affiliated with New York-Presbyterian Hospital to test the effectiveness of a theory-informed multifaceted implementation strategy designed to increase the uptake of the 2015 United States Preventive Services Task Force (USPSTF) hypertension screening guidelines. The primary outcome is the ordering of out-of-office blood pressure testing, either ambulatory blood pressure monitoring (ABPM) or home blood pressure monitoring (HBPM), by primary care clinicians for patients with newly elevated office blood pressure (BP), as recommended by the 2015 guidelines.
