RESUMEN
BACKGROUND: Rose-scented geranium, Pelargonium spp., essential oils from the cultivars 'Bourbon', 'China', 'Egypt', 'Rober's Lemon Rose' and 'Frensham' were analyzed by GC-FID and GC-MS. A total of 136 compounds were identified from five essential oils, constituting 85.5-99.7% of the oils. Essential oils and pure compounds were evaluated for their insecticidal activity against Stephanitis pyrioides and larvicidal and biting deterrent activity against Aedes aegypti. RESULTS: All five geranium oils were toxic to S. pyrioides, and four of these five were more potent than malathion and neem. Trans-nerolidol (LD50 = 13.4 ppm) was the most toxic compound against one-day-old Ae. aegypti larvae, followed by geraniol (49.3 ppm), citronellol (49.9 ppm) and geranyl formate (58.5 ppm). Essential oil of cultivar 'Egypt' at 100 µg cm(-2) [biting deterrent index (BDI) = 0.8] showed the highest biting deterrent activity, followed by cultivars 'Frensham' (BDI = 0.76), 'China' (BDI = 0.72), 'Rober's Lemon Rose' (BDI = 0.63) and 'Bourbon' (BDI = 0.45) essential oils. Among the pure compounds, the biting deterrent activity of geranic acid (BDI = 0.99) was not significantly different from that of N,N-diethyl-m-toluamide (DEET). CONCLUSION: Essential oils and pure compounds showed insecticidal activity against S. pyrioides and Ae. aegypti. The high biting deterrent activity of geranic acid points to the need for further research.

OBJECTIVE: To develop pharmacist practice standards, pharmacy preceptor standards, and objectives for students completing advanced practice community pharmacy rotations. SETTING: Ohio. PRACTICE DESCRIPTION: Pharmacy schools and community pharmacies that serve as advanced practice rotation sites. PRACTICE INNOVATION: Developed standards for preceptors and objectives for student experiences. INTERVENTIONS: Focus groups that included both community pharmacists and pharmacy faculty collaborated on defining key standards for advanced community pharmacy rotations. MAIN OUTCOME MEASURE: Not applicable. RESULTS: Three main documents were produced in this initiative, and these are provided as appendices to this article. Professional and patient care guidelines for preceptors define minimum standards for these role models. Expectations of pharmacists as preceptors provide insights for managing this student-teacher relationship, which is fundamentally different from the more common employer-employee and coworker relationships found in pharmacies of all types. Objectives for student experiences during advanced practice community pharmacy rotations present core expectations in clinical, dispensing, patient education, wellness, and drug information areas. CONCLUSION: Through this collaboration, Ohio colleges of pharmacy developed a partnership with practitioners in community settings that should enhance the Ohio experiential educational program for student pharmacists. Use of the established guidelines will help educators and practitioners achieve their shared vision for advanced practice community pharmacy rotations and promote high-quality patient care.
