Objective: During the past decade, the availability of health information online has increased dramatically. We assessed progress toward the Healthy People 2020 (HP2020) health communication and health information technology objective of increasing the proportion of health information seekers who easily access health information online. Methods: We used data from 4 administrations of the Health Information National Trends Survey (HINTS 2008-2017) (N = 18 103). We conducted multivariable logistic regression analysis to evaluate trends over time in experiences with accessing health information and to examine differences by sociodemographic variables (sex, age, race/ethnicity, education, income, metropolitan status) separately for those who used the internet (vs other information sources) during their most recent search for health information. Results: Among US adults who looked for health information and used the internet for their most recent search, the percentage who reported accessing health information without frustration was stable during the study period (from 37.2% in 2008 to 38.5% in 2017). Accessing information online without frustration was significantly and independently associated with age 35-49 (vs age 18-34) (odds ratio [OR] = 1.34; 95% confidence interval [CI], 1.03 -1.73), non-Hispanic black (vs non-Hispanic white) race/ethnicity (OR = 2.15; 95% CI, 1.55-2.97), and annual household income <$20 000 (vs >$75 000) (OR = 0.66; 95% CI, 0.47-0.93). The percentage of adults who used an information source other than the internet and reported accessing health information online without frustration ranged from 31.3% in 2008 to 42.7% in 2017. Survey year 2017 (vs 2008) (OR = 1.61; 95% CI, 1.09-2.35) and high school graduate education (vs college graduate) (OR = 0.69; 95% CI, 0.49-0.97) were significantly and independently associated with accessing health information without frustration from sources other than the internet. Conclusions: The percentage of online health information seekers reporting easily accessing health information did not meet the HP2020 objective. Continued efforts are needed to enable easy access to online health information among diverse populations.

Purpose To pilot test the impact of the ICAN Discussion Aid on clinical encounters. Methods A pre–post study involving 11 clinicians and 100 patients was conducted at two primary care clinics within a single health system in the Midwest. The study examined clinicians’ perceptions about ICAN feasibility, patients’ and clinicians’ perceptions about encounter success, videographic differences in encounter topics, and medication adherence 6 months after an ICAN encounter. Results 39/40 control encounters and 45/60 ICAN encounters yielded usable data. Clinicians reported ICAN use was feasible. In ICAN encounters, patients discussed diet, being active and taking medications more. Clinicians scored themselves poorer regarding visit success than their patients scored them; this effect was more pronounced in ICAN encounters. ICAN did not improve 6-month medication adherence or lengthen visits. Conclusion This pilot study suggests that using ICAN in primary care is feasible, efficient and capable of modifying conversations. With lessons learned in this pilot, we are conducting a randomised trial of ICAN versus usual care in diverse clinical settings. Trial registration number NCT02390570 .

Abstract OBJECTIVE: To determine the role of grape extract as a potential aromatase inhibitor by testing of plasma hormone levels. PROCEDURE: A six-week study was conducted involving postmenopausal women during which 94 grams of grape extract was consumed in addition to their usual diet. Plasma hormones were measured before and after treatment. RESULTS: Of the 18 women involved in the study, average age and BMI were 61.4 years and 24.4, respectively. For the hormone levels studied, the following median (IQR) percent change from baseline to 6 weeks values were found: estradiol +11.8% (-34.4%,+44.2%), p = 0.42; estrone +3.4% (-15.7%,+12.9%), p = 0.64; estrone sulfate +5.3% (-19.9%,+56.3%), p = 0.35; testosterone -1.5% (-14.7%,+10.7%), p = 0.97; androstenedione +12.6% (-17.1%, +49.1%), p = 0.15. The hormone levels did not significantly change between baseline and six weeks. Further, the changes that were observed did not tend to go in the hypothesized direction (estrogens and conjugates increased slightly, testosterone decreased slightly). Only androstenedione showed a trend toward change in the hypothesized direction. CONCLUSION: In this study, there was no evidence that plasma hormone levels are altered by 6 weeks of daily consumption of 94 grams of grape extract powder. Citation Format: Janet E. Olson, Summer V.

The development of pharmacologic agents for the prevention of breast cancer is a significant milestone in medical and laboratory research. Despite these advances, the endorsement of preventive options has become challenging and complex, as physicians are expected to counsel and tailor their recommendations using a personalized approach taking into account medical comorbidities, degree of risk and patient preferences. This article provides a comprehensive overview of the major breast cancer prevention trials, review of the pharmacologic options available for breast cancer prevention, and strategies for integrating chemoprevention of breast cancer in high-risk women into clinical practice.
