Wei-Hsuan Jenny Lo-Ciganic, PhD, MSCP, MS, is an Assistant Professor in the University of Arizona College of Pharmacy Department of Pharmacy, Practice and Science, and the University of Arizona College of Public Health, Department of Epidemiology and Biostatistics. She is a pharmacoepidemiologist and biostatistician who has interests in medication adherence to essential chronic medications, drug safety, cancer prevention, quality and value of prescribing, and diffusion of new drugs for chronic disease management, especially among populations who are vulnerable or minorities. Several of her previous projects have focused on evaluating cholesterol-lowering medication use in older adults, associations between statin use and physical function decline in older adults, and associations between non-opioid analgesics and risk of ovarian cancer. She has been involved in the largest population-based case-control study of ovarian cancer in the U.S (Hormone and Ovarian Cancer Prediction [HOPE] Study) and the Ovarian Cancer Association Consortium (OCAC). Methodologically, Dr. Lo-Ciganic is experienced in a wide range of both quantitative and qualitative methods. She has expertise in analyses of big health care data, supervised machine-learning methods, group based trajectory models, and the development and evaluation of an integrated program intervention with a community-based design.
Dr. Lo-Ciganic received her pharmacy degree from National Taiwan University (Taipei, Taiwan) in 2003, and a MS in Clinical Pharmacy from National Cheng-Kung University (Tainan, Taiwan) in 2005. She also completed a MS in Biostatistics at the University of Pittsburgh in 2010 and received her PhD in Epidemiology at the University of Pittsburgh in 2013. Prior to arriving at the University of Arizona, she worked as a post-doctoral associate for the Center for Pharmaceutical Policy and Prescribing at the University of Pittsburgh Health Policy Institute. In that role, she collaborated on a variety of studies focused on application of novel statistical methods for improving medication adherence measures in diabetes and treatment for opioid use disorders. Her long-range career objective is to conduct pharmacoepidemiologic, comparative effectiveness and health service research to better understand the patient, provider, health system, and regional factors that impact drug utilization to inform clinical medicine, health promotion, and health policy, and ultimately to improve health outcomes and quality. She is a recipient of both the 2015 Faculty Seed Grant (University of Arizona Office for Research and Discovery), and University of Arizona Health Sciences Center Career Development Award. She is also a recipient of the 2016 American Association of College of Pharmacy New Investigator Award. Her recent work is focused on using machine learning approaches to prevent problematic prescription opioid use.

Formulary management tools adopted by payers, specifically prior authorization (PA) policies, may lower the rates of opioid medication abuse and overdose. We compared rates of opioid abuse and overdose among enrollees in plans that varied in their use of PA from "High PA" (ie, required PA for 17 to 74 opioids), with "Low PA" (ie, required PA for 1 opioid), and "No PA" policies for opioid medications.

Substance abuse, 36(2), 192-202.More infoHealth insurance claims data may play an important role for health care systems and payers in monitoring the nonmedical use of prescription opioids (NMPO) among patients. However, these systems require valid methods for identifying NMPO if they are to target individuals for intervention. Limited efforts have been made to define NMPO using administrative data available to health systems and payers. We conducted a systematic review of publications that defined and measured NMPO within health insurance claims databases in order to describe definitions of NMPO and identify areas for improvement.

Pilot Enhancement of the Arthritis Foundation Exercise Program with a Healthy Aging Program. Research in gerontological nursing, 1-10.More infoOlder adults with arthritis or joint pain were targeted for a pilot program enhancing the Arthritis Foundation Exercise Program with the 10 Keys™ to Healthy Aging Program. Using a one-group, pre-post design, feasibility was examined and improvements in preventive behaviors, arthritis outcomes, and cardiometabolic outcomes were explored. A 10-week program was developed, instructors were recruited and trained, and four sites and 51 participants were recruited. Measures included attendance, adherence, satisfaction, preventive behaviors, Western Ontario and McMaster Universities Osteoarthritis Index (pain and stiffness), glucose, and cholesterol. Three fourths of participants attended >50% of the sessions. At 6 and 12 months, more than one half performed the exercises 1 to 2 days per week, whereas 28% and 14% exercised 3 to 7 days per week, respectively. Participants (92%) rated the program as excellent/very good. Nonsignificant changes were observed in expected directions. Effect sizes were small for arthritis and cardiometabolic outcomes. This program engaged community partners, demonstrated feasibility, and showed improvements in some preventive behaviors and health risk profiles. [Res Gerontol Nurs. 2015; x(x):xx-xx.].

Genital powder use and risk of ovarian cancer: a pooled analysis of 8,525 cases and 9,859 controls. Cancer prevention research (Philadelphia, Pa.), 6(8), 811-21.More infoGenital powder use has been associated with risk of epithelial ovarian cancer in some, but not all, epidemiologic investigations, possibly reflecting the carcinogenic effects of talc particles found in most of these products. Whether risk increases with number of genital powder applications and for all histologic types of ovarian cancer also remains uncertain. Therefore, we estimated the association between self-reported genital powder use and epithelial ovarian cancer risk in eight population-based case-control studies. Individual data from each study were collected and harmonized. Lifetime number of genital powder applications was estimated from duration and frequency of use. Pooled ORs were calculated using conditional logistic regression matched on study and age and adjusted for potential confounders. Subtype-specific risks were estimated according to tumor behavior and histology. 8,525 cases and 9,859 controls were included in the analyses. Genital powder use was associated with a modest increased risk of epithelial ovarian cancer [OR, 1.24; 95% confidence interval (CI), 1.15-1.33] relative to women who never used powder. Risk was elevated for invasive serous (OR, 1.20; 95% CI, 1.09-1.32), endometrioid (OR, 1.22; 95% CI, 1.04-1.43), and clear cell (OR, 1.24; 95% CI, 1.01-1.52) tumors, and for borderline serous tumors (OR, 1.46; 95% CI, 1.24-1.72). Among genital powder users, we observed no significant trend (P = 0.17) in risk with increasing number of lifetime applications (assessed in quartiles). We noted no increase in risk among women who only reported nongenital powder use. In summary, genital powder use is a modifiable exposure associated with small-to-moderate increases in risk of most histologic subtypes of epithelial ovarian cancer.
