Developing and implementing an HIV/AIDS educational curriculum for older adults.

PURPOSE: Recent data (2002) from the Centers for Disease Control and Prevention indicate that almost 11% of all cases of AIDS were diagnosed in people 50 and older. Despite the steady rise and future projections of increase, there is still a paucity of education and prevention programs targeting this population. This article reports on the development and piloting of an HIV/AIDS education prevention program. It describes an educational curriculum that provides older adults with accurate information about the relevance of HIV/AIDS to their lives. DESIGN AND METHODS: A purposive sample (n = 249) of ethnically and economically diverse adults 50 years and older was selected from 14 organizations in rural and urban settings in California. They were surveyed to determine their interest in participating in HIV/AIDS education prevention programs. RESULTS: A majority of participants reported interest in an HIV/AIDS prevention program for older people, with female respondents more likely to attend than male respondents. Participants who were moderately or very religious were also more likely to attend. Participants expressed preference for prevention education through presentations at centers serving older adults, and from physicians and other health care providers. On the basis of these findings, a specialized curriculum targeting older adults was developed, presented, and disseminated. IMPLICATIONS: People 50 years and older are sexually active, lack accurate information about HIV/AIDS, and are in need of HIV/AIDS education.

Evolution of ventricular function during permanent pacing from either right ventricular apex or outflow tract following AV-junctional ablation for atrial fibrillation.

AIMS: To compare acute and chronic ventricular function between patients, without cardiac failure, paced at either right ventricular apex or outflow tract. METHODS: Twenty patients. 10 paced apically and 10 in the outflow tract, underwent two radionuclide ventriculograms. Eight parameters of systolic or diastolic function were compared at each assessment, as were changes within each group over time. RESULTS: No differences were identified in systolic function between pacing sites 6 weeks after pacing or 23 weeks later. Peak filling rate was lower (P=0.04) at the second assessment with outflow tract pacing. No other diastolic differences were identified. Between assessments, time to peak filling rate prolonged (P=0.04) with apical pacing, while left ventricular area reduced (P=0.04) and peak filling rate decreased (P=0.04) with outflow tract pacing. Septal motion was better preserved with outflow tract pacing. No other parameter changed over time. ECG measures were similar at 14.7 months. CONCLUSIONS: No major differences were identified in systolic function between pacing sites. Some systolic parameters were better preserved with outflow tract pacing and diastolic function deteriorated subtly over time in both groups. Right ventricular pacing adversely affects left ventricular function.
