End-of-Life Dementia Costs More Than Heart D,.Cancer

Pauline Anderson
October 30, 2015
The study, which investigated social costs and financial risks faced by Medicare beneficiaries during the 5 years before death, found that healthcare spending for dementia topped $250,000 per person, about 57% more than costs associated with death from other diseases, including cancer and heart disease.
The new analysis, carried out by Amy S. Kelley, MD, Icahn School of Medicine at Mount Sinai, New York, New York, and colleagues, was published online October 27 in the Annals of Internal Medicine.
"This complex analysis lays out the significant health care costs to society and individuals" at the end of life, said Richard J. Hodes, MD, director, National Institute on Aging (NIA), which funded the analysis, in a press release./.../
 

Telomere and AD

Megan Brooks

October 30, 2015 Shortening a Cause of Alzheimer's Disease?

A new study provides evidence for the first time of a causal relationship between telomere length (TL) and Alzheimer's disease (AD), say investigators from Sweden.
"This is the first study addressing the causal effect of TL on AD," principal investigator Sara Hägg, PhD, docent of molecular epidemiology, Karolinska Institutet, Stockholm, toldMedscape Medical News.
Telomeres are repetitive DNA sequences at the ends of chromosomes that progressively shorten with age. Observational studies suggest that shorter telomeres are associated with shorter life expectancy and greater risk for age-related diseases, including AD. However, these studies could have residual confounding or reverse causation, making it difficult to draw conclusions on whether TL is causally associated with AD./.../

Ageing Cities

24 Sep 2015

Arup has launched “Shaping Ageing Cities” – a new report that analyses how ten European cities are responding to ageing. Cover of the report. Credit: Arup.

We are living in the urban and ageing era. In 2050, for the first time in human history, the number of older people will be greater than the number of children under 15 years old. As cities across the globe continue to grow, more people are growing old in housing, streets, communities that often are failing to respond appropriately to ageing populations with specific policies.
How can cities respond to this demographic change and deliver appropriate solutions? This forward-thinking report, undertaken by Arup in collaboration with HelpAge InternationalIntel ICRI Cities and Systematicaaddresses this global concern through a comparative overview of the performance of 10 European cities.
The report analyses these key issues according to ageing data and observing them under the lenses of society, mobility, built and digital environment and sets up the basis to further investigate the correlation among politics, planning and ageing.
"Cities and urban environments have a fundamental role in defining how to deal with our ageing society. This provides a unique opportunity to influence and design urban environments and social structures in ways that respect, protect and fulfil our rights, including in our older age."
—Stefano Recalcati, Associate, Milan
Shaping Ageing Cities defines a methodology to study ageing in European cities; understanding main features such as transportation, income, outdoor spaces, building design, social inclusion, ICT and health services in order to apply this experience to the growing market related to city-making.

Australian academics seek to challenge 'web of avarice' in scientific publishing

In the wake of editor-in-chief Stephen Leeder’s sacking from the Medical Journal of Australia, academics are challenging the control of a select group of publishing houses over scientific journals
Mitchell Library Reading Room at the State Library of New South Wales
Leeder told Guardian Australia he still felt “pretty beaten up” by the MJA experience, knowledge and scholarly information had gone from being a public good to a “commercial, tradable commodity”.
“The whole academic publishing industry is a gigantic web of avarice and selfishness, and the academic community has not engaged to the extent it perhaps should have to stop it,” Leeder said.
“Scholarly publishing is a bit like the Trans-Pacific Partnership Agreement. It’s not totally clear what the hell is going on, but you can be sure someone is making a hell of a lot of money from it.”/.../

Microglia

Rise of the Microglia

New research shows that the resident immune cells of the brain are involved in both development and disease



©iStock.com
Microglia, the immune cells of the brain, have long been the underdogs of the glia world, passed over for other, flashier cousins, such as astrocytes. Although microglia are best known for being the brain’s primary defenders, scientists now realize that they play a role in the developing brain and may also be implicated in developmental and neurodegenerative disorders. The change in attitude is clear, as evidenced by the buzz around this topic at this year’s Society for Neuroscience (SfN) conference, which took place from October 17 to 21 in Chicago, where scientists discussed their role in both health and disease.
Activated in the diseased brain, microglia find injured neurons and strip away the synapses, the connections between them. These cells make up around 10 percent of all the cells in the brain and appear during early development. For decades scientists focused on them as immune cells and thought that they were quiet and passive in the absence of an outside invader. That all changed in 2005, when experimenters found that microglia were actually the fastest-moving structures in a healthy adult brain. Later discoveries revealed that their branches were reaching out to surrounding neurons and contacting synapses. These findings suggested that these cellular scavengers were involved in functions beyond disease.
The Brain’s Sculptors 
The discovery that microglia were active in the healthy brain jump-started the exploration into their underlying mechanisms: Why do these cells hang around synapses? And what are they doing?/.../
