Formative Development of a Technology-Based Physical Activity Intervention for Grandparents and Grandchildren.

Physical inactivity is a major public health issue among older adults and children. This study presents preliminary results that will inform the development of a technology-based physical activity intervention for grandparents and grandchildren (ages 6-12 years old). The authors used an iterative user-centered design framework to gather quantitative data from grandparents (n = 35) and subsequently invited a subset of 12 of them to engage in qualitative interviews. Participants were 63.1 ± 9.8 years old, 80% female, 64% U.S.-born, 43% Hispanic, 66% single, and 40% <$15K income. The majority of grandparents reported mobile device proficiency, very close relationships with their grandchildren, and interest in participating in an intergenerational intervention. Four key themes related to family closeness, dynamics, routines, and technology informed intervention development. Next steps involved a pilot trial using Fitbits and a fully functioning technology-based prototype. Grandparents are uniquely positioned within their families to serve as agents of change in health-promoting interventions.

Is DCIS Overrated?

Ductal carcinoma in situ (DCIS), the noninvasive form of breast cancer (BC), comprises just over 20% of breast cancer cases diagnosed each year in the USA. Most patients are treated with local excision of the disease followed by whole breast radiation therapy. Total mastectomy is not an uncommon approach, and total mastectomy with a contralateral risk-reducing mastectomy has been on the rise in the past decade. In estrogen receptor-positive disease, patients are often offered endocrine ablative therapy with a selective estrogen receptor modulator or an aromatase inhibitor as both treatment and prevention. Local regional treatment options have no impact upon ultimate overall survival. Long-term survival rates are higher in patients with DCIS than with any other form of the disease. Are these strikingly high success rates a testament to effective treatment strategies or is there a significant subset of DCIS that was unlikely to ever progress to invasive ductal carcinoma? DCIS was not seen in the US prior to the advent of screening mammography. When compared to other countries, the USA has the highest utilization of screening mammography and the incidence rate of DCIS. Other lines of evidence include autopsy series examining the breast tissue of women who died of other causes, missed-diagnosis series and current retrospective reviews of DCIS, all align in support of the concept of DCIS as indolent in the majority of cases [3-14]. The evidence suggests that both patient and physician misconceptions about DCIS have led to overdiagnosis and over-treatment of DCIS. Recently, a gene expression profiling tool (12 gene assay, Oncotype DCIS) has emerged that shows considerable promise in predicting class in DCIS patients.
