Progressive neurodegenerative diseases plague millions of individuals both in the United States and across the world. The current pathology of progressive neurodegenerative tauopathies, such as Alzheimer's disease (AD), Pick's disease, frontotemporal dementia (FTD), and progressive supranuclear palsy, primarily revolves around phosphorylation and hyperphosphorylation of the tau protein. However, more recent evidence suggests acetylation of tau protein at lysine 280 may be a critical step in molecular pathology of these neurodegenerative diseases prior to the tau hyperphosphorylation.

This paper is based upon findings from the qualitative element of a mixed-methods study on the response of Black women aged 25-50 to a public health intervention related to breast cancer. The focus groups were conducted in the London Borough of Hackney, UK between 2013 and 2016, and were part of an evaluation of the effectiveness of a breast awareness DVD. While the content of the DVD was generally well-received by the participants, the focus group discussions revealed a complex and, at times, contradictory response to the women's construction as an 'at risk' community.

Background: The mean age of presentation for breast cancer among black women is substantially earlier than their white counterparts. Black women also present with adverse prognostic factors that have major clinical implications, including lower survival. To pilot the use of a 6 min DVD on breast cancer in young (under 50 years) black women, to raise awareness and examine the impact of the DVD on increased consultation and referral rates among these women.

Ductal carcinoma in situ (DCIS) now represents up to 20% of breast cancer cases, yet its behaviour is still poorly understood. Morphological classifications go some way to predicting prognosis, but more sophisticated approaches are required to better tailor therapy to the individual. A number of biological molecules have been identified that appear to relate to prognosis and, in model systems, promote progression to invasive disease.
