Insulin resistance is a central feature of the PCOS and may increase cardiovascular risk. Owing to insulin resistance, the metabolic syndrome is more prevalent in women with PCOS compared with unaffected women. Metformin improves the metabolic profile in PCOS in short-term studies. In this study, we evaluated the long-term effect of metformin on metabolic parameters in women with PCOS during routine care without a controlled diet.We performed a retrospective medical chart review of 70 women with PCOS receiving metformin from an academic endocrine clinic. Metabolic risk factors were compared before and after metformin treatment. Time trends of these metabolic parameters were also analysed. After a mean follow-up of 36.1 months with metformin treatment, improvements were observed for BMI (—1.09 ± 3.48 kg/m2, p = 0.0117), diastolic blood pressure (—2.69 ± 10.35 mmHg, p = 0.0378), and HDL cholesterol (+5.82 ± 11.02 mg/dL, p <0.0001).The prevalence of metabolic syndrome decreased from 34.3% at baseline to 21.4% (p = 0.0495). The course of BMI reduction during metformin treatment was significantly more pronounced in women with PCOS with metabolic syndrome at baseline, compared with those without the metabolic syndrome (p = 0.0369 for interaction). In conclusion, metformin improved the metabolic profile of women with PCOS over 36.1 months, particularly in HDL cholesterol, diastolic blood pressure and BMI.
Objective. To compare educational outcomes between two iterations of a scholarship and research course for Doctor of Pharmacy (PharmD) students at Virginia Commonwealth University's School of Pharmacy. Methods. The first iteration of a course intended to teach pharmacy students the knowledge and skills necessary to design and conduct research involved lectures and application exercises, including limited guided questions about different aspects of the research process. In the fall of 2015, multiple structured activities and accompanying grading rubrics, each designed around the structure and content of a section of a research proposal, were introduced to the course to supplement lectures. Both iterations of the course culminated with students submitting a research proposal. After establishing interrater reliability, faculty members graded a random sample of 20 research proposals, 10 from each version of the course, and section-specific and overall proposal scores were compared. Results. In the proposals submitted after the course revisions, significant improvements in three areas were identified: the overall score, the section-specific scores for research hypothesis/specific aims, and institutional review board (IRB) discussion/informed consent. Nominal, though not statistically significant, improvements were observed in other sections. Conclusion. Additional research is needed regarding the best instructional strategies to reinforce data analysis and statistical testing knowledge and skills in PharmD students. Overall, our findings support the hypothesis that a more formalized, guided approach for teaching research methods improves learning outcomes for PharmD students.
