African American women are more likely to suffer higher rates of uncontrolled hypertension than non-Hispanic white women. Prime Time Sister Circles® (PTSC) empowers women to proactively manage their blood pressure by promoting the effective use of preventive health care; encouraging self monitoring of blood pressure, and teaching strategies for managing stress, increasing physical activity, and improving nutrition. The 12-week community-based, holistic lifestyle intervention aims to improve blood pressure control by improving health knowledge, health efficacy, and health behaviors. PTSC potentially reduces health care costs through prevention, earlier detection, and improved management of hypertension through a culturally tailored program addressing specific barriers experienced by midlife and late life African American women. This 5-year study is a collaboration between The Johns Hopkins Center for Health Disparities Solutions (HCHDS), The Gaston \& Porter Health Improvement Center, Inc. (GPHIC), and the American Institutes for Research (AIR). The investigators seek to determine the impact and cost-effectiveness of the PTSC intervention among low-income African American women with uncontrolled hypertension. To do this, the investigators will randomly assign 600 women between the ages of 40 and 75 who receive their care from an federally qualified health center (FQHC) to either PTSC (n=300) or a comparison group (n=300) who will receive the PTSC intervention after they have been observed for 15 month. Using data from in person surveys and clinical measures conducted during in-person data collection meetings, the investigative team will determine if PTSC help low-income African American women effectively manage their blood pressure.

Temporary transcutaneous cardiac pacing is a life-saving procedure in patients with unstable bradycardia. The American Heart Association (AHA) guidelines for the management of unstable bradycardia recommend initiating transcutaneous pacing in patients unresponsive to atropine while addressing the primary cause of the bradycardia. The two most commonly described pacer pad application sites are the anterior-posterior (A-P) position (positive pad placed under the left scapula and negative pad placed on the left anterior lower chest wall) and the anterior-lateral (A-L) position (positive pad placed on the right anterior chest wall and negative pad placed on the left lower axilla). Major resuscitation organization (AHA, European, Australian) guidelines and text books of emergency medicine recommendations for pacer pad placement do not address the issue of which set of positions are preferred. There are no published human studies addressing ideal pacer pad placement. This study's objective is to assess if there is a significant difference in the pacing threshold (mA) between these two pacer pad positions. The study hypothesis is that the anterior-posterior position will require a lower current and cause less involuntary muscle contraction. The investigators plan to enroll volunteer human subjects undergoing elective cardioversion in the electrophysiology laboratory for atrial fibrillation/flutter. After successful cardioversion to a sinus rhythm, each subject will be transcutaneously paced to mechanical capture in both pacer pad positions. Optimal placement will be determined by the pad position with the lowest current required for capture. The conclusions of this study will provide evidence for the optimal choice regarding pacer pad placement, which can be used in future resuscitation guidelines.
