Persistence with Mammography Screening and Stage at Breast Cancer Diagnosis among Elderly Appalachia-West Virginia Women

The objective of this study is to evaluate the association between persistence with mammography screening and stage at breast cancer diagnosis in elderly Appalachia-West Virginia women diagnosed with first incident breast cancer. The study utilized West Virginia Cancer Registry-Medicare linked database to identify women age 70 and above diagnosed with first incident breast cancer in 2007. Persistence to mammography screening was defined as having had at least three mammography screenings before breast cancer diagnosis. A multiple logistic regression was conducted to assess the association between persistence with mammography screening and stage at breast cancer diagnosis in these women. Of the 221 elderly Appalachia-West Virginia women included in the analysis, 113 women (51.1%) were persistent to mammography screening before their diagnosis with breast cancer. In a multiple logistic regression after adjusting for all the variables, as compared to elderly women who were not persistent with mammography screening, women who were persistent with mammography screening were significantly more likely to be diagnosed with early stage breast cancer (adjusted odds ratio=4.25, 95% confidence interval=1.96-9.19). Persistence with mammography screening is significantly associated with earlier stages of breast cancer in the rural and underserved Appalachia-West Virginia women. The study findings suggest targeting interventions to encourage regular mammography in these women for whom there are no clear guidelines

Evidence of Songbird Intoxication From Rozol Application at a Black-Tailed Prairie Dog Colony

Concerns about avian poisonings from anticoagulant rodenticides have traditionally focused on secondary poisoning of raptors exposed by feeding on contaminated mammalian prey. However, ground foraging songbirds can be directly poisoned from operational applications of the anticoagulant rodenticide RozolH (0.005% chlorophacinone, active ingredient) applied as a grain bait, at black-tailed prairie dog Cynomys ludovicianus colonies. A dead western meadowlark Sturnella neglecta recovered from the study prairie dog colony displayed hemorrhaging in brain and pectoral muscle tissue, and it contained chlorophacinone residue concentrations of 0.59 and 0.49 mg/g (wet weight) in the liver and intestinal contents, respectively. Chlorophacinone residues from two Rozol-colored songbird droppings found at the study colony were 0.09 and 0.46 mg/g (wet weight). The timing of the meadowlark mortality and the occurrence of discolored droppings show that songbird exposure and poisoning can occur weeks after a Rozol application

Collaborative Practices that Support Creativity in Design

Design is a ubiquitous, collaborative and highly material activity. Because of the embodied nature of the design profession, designers apply certain collaborative practices to enhance creativity in their everyday work. Within the domain of industrial design, we studied two educational design departments over a period of eight months. Using examples from our fieldwork, we develop our results around three broad themes related to collaborative practices that support the creativity of design professionals: 1) externalization, 2) use of physical space, and 3) use of bodies. We believe that these themes of collaborative practices could provide new insights into designing technologies for supporting a varied set of design activities. We describe two conceptual collaborative systems derived from the results of our study
