RESUMEN

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. As the paper highlights, for many of the women, breast cancer remains a disease of whiteness and the information provided in the DVD prompted a range of emotional responses; from anxiety and fear to a desire to become more knowledgeable and active in the promotion of self-care. As the paper argues, of particular importance to the women was the need to feel a much stronger emotional connection to the information presented in the DVD. The paper concludes by arguing that placing greater emphasis on feeling and emotion is an important dimension of future research in this area.

RESUMEN

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. Secondary injury cascades such as oxidative stress, endoplasmic reticulum stress, and neuroinflammation contribute to lasting damage within the brain and can be induced by a number of different risk factors. These injury cascades funnel into a common pathway of early tau acetylation, which may serve as the catalyst for progressive degeneration. The post translational modification of tau can result in production of toxic oligomers, contributing to reduced solubility as well as aggregation and formation of neurofibrillary tangles, the hallmark of AD pathology. Chronic Traumatic Encephalopathy (CTE), caused by repetitive brain trauma is also associated with a hyperphosphorylation of tau. We postulated acetylation of tau at lysine 280 in CTE disease could be present prior to the hyperphosphorylation and tested this hypothesis in CTE pathologic specimens. We also tested for ac-tau 280 in early stage Alzheimer's disease (Braak stage 1). Histopathological examination using the ac tau 280 antibody was performed in three Alzheimer's cases and three CTE patients. Presence of ac-tau 280 was confirmed in all cases at early sites of disease manifestation. These findings suggest that tau acetylation may precede tau phosphorylation and could be the first "triggering" event leading to neuronal loss. To the best of our knowledge, this is the first study to identify acetylation of the tau protein in CTE. Prevention of tau acetylation could possibly serve as a novel target for stopping neurodegeneration before it fully begins. In this study, we highlight what is known about tau acetylation and neurodegeneration.

RESUMEN

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. METHODS: Two general practices (intervention practices) in the Hackney area were randomised to have the DVD mailed to all black women aged 25-50 years registered with the practices, and two practices to no intervention (control practices). EMIS data was used to compare consultation rates preintervention and postintervention, in the intervention as well as control practices. Interviews with practice staff and focus groups with patients in participating practices provided qualitative data on the study context and DVD effectiveness. RESULTS: A trend of declining consultations for breast symptoms was observed (-22% and -31% among non-black women in the control and intervention practices, and -23% among black women in the control practice) except among the target population of black women aged 25-50 years for the DVD in the intervention practices, which saw an increase of 28% in consultations. The qualitative data indicated that the DVD was well received in the target population, and suggested further ways of disseminating awareness messages and overcoming barriers to help-seeking. CONCLUSIONS: Pilot results suggest that the strategy of distributing the DVD may increase consultations for breast problems.

RESUMEN

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. Some of these, such as COX-2, provide real therapeutic opportunities, whilst other marker combinations are showing promise in categorising women according to risk. Gene expression studies have led to an emerging molecular classification of invasive breast cancer, and it is now evident that at least some of these molecular subtypes can be identified at the pre-invasive stage. The difference in frequency of these subtypes between DCIS and invasive cancer may hold clues as to the biological mechanisms underpinning disease transition. It is increasingly clear that the host microenvironment can have a major impact on disease behaviour, and as well as acting as potential predictive factors, the altered microenvironment phenotype also offers novel therapeutic opportunities.
