Pharmacogenomic Genome-Wide Meta-Analysis of Blood Pressure Response to β-Blockers in Hypertensive African Americans.

African Americans suffer a higher prevalence of hypertension compared with other racial/ethnic groups. In this study, we performed a pharmacogenomic genome-wide association study of blood pressure (BP) response to β-blockers in African Americans with uncomplicated hypertension. Genome-wide meta-analysis was performed in 318 African American hypertensive participants in the 2 Pharmacogenomic Evaluation of Antihypertensive Responses studies: 150 treated with atenolol monotherapy and 168 treated with metoprolol monotherapy.

PTPRD gene associated with blood pressure response to atenolol and resistant hypertension.

Objective: The aim of this study is to identify single-nucleotide polymorphisms (SNPs) influencing blood pressure (BP) response to the β-blocker atenolol.

Methods: Genome-wide association analysis of BP response to atenolol monotherapy was performed in 233 white participants with uncomplicated hypertension in the pharmacogenomic evaluation of antihypertensive responses study. Forty-two polymorphisms with P less than 10 for association with either diastolic or systolic response to atenolol monotherapy were validated in four independent groups of hypertensive individuals (total n = 2114).

Predictors for glucose change in hypertensive participants following short-term treatment with atenolol or hydrochlorothiazide.

Study Objective: To develop and validate a predictive model for glucose change and risk for new-onset impaired fasting glucose in hypertensive participants following treatment with atenolol or hydrochlorothiazide (HCTZ).

Design: Randomized multicenter clinical trial.

Patients: A total of 735 white or African-American men and women with uncomplicated hypertension.

Hindbrain oxytocin receptors contribute to the effects of circulating oxytocin on food intake in male rats.

Oxytocin (OT)-elicited hypophagia has been linked to neural activity in the nucleus of the solitary tract (NTS). Because plasma OT levels increase after a meal, we hypothesized that circulating OT acts at both peripheral and hindbrain OT receptors (OTRs) to limit food intake. To initially determine whether circulating OT inhibits food intake by acting at hindbrain OTRs, we pretreated rats with an OTR antagonist administered into the fourth ventricle (4V) followed by either central or systemic OT administration.

Knowledge and attitudes of primary care physicians regarding prostate cancer screening.

Introduction: We report the results of a questionnaire administered to primary care physicians to determine their baseline knowledge of prostate cancer and their attitudes on prostate cancer screening.

Materials And Methods: A 27-item questionnaire designed to assess prostate cancer knowledge and screening attitudes was administered to primary care physicians in Duval and Alachua counties. Completed surveys were returned, entered into the master database and analyzed.

Assessments for measuring patient-centered cultural sensitivity in community-based primary care clinics.

Objective: To develop and test the reliability of three race/ethnicity-specific forms of the pilot Tucker-Culturally Sensitive Health Care Inventory (T-CUSHCI) for use by patients at community-based primary care centers to evaluate the level of patient-centered cultural sensitivity perceived in the health care that they experience.

Methods: This research involved two studies using independent samples of primary care patients. In study 1, mostly low-income African-American, Hispanic and non-Hispanic white American patients (N=221) rated the importance of specific provider and office staff behaviors and attitudes, and center policies and physical environment characteristics that were earlier identified in previous focus groups as characteristics of patient-centered culturally sensitive healthcare.
