The huge drive to immunize the masses against threat of H1N1 in the 2009/10 influenza season (which the WHO has officially declared concluded) has created more than a watershed moment in 21st century public health response to a potential biological catastrophe, it has also touched off a political debate that’s just getting started. And it all has to do with authoritarian mandate of the vaccine for healthcare workers.
Contrary to popular thought, many healthcare workers do not receive the vaccine; in fact, approximately 40 percent of said workers actively refused [PDF link] the vaccine last year — during infection’s peak. This notion does not sit well with a couple of policy organizations — one academic and one medical. Both groups say mandatory influenza vaccine should be a condition of employment. The groups stress increased availability of the vaccine, a steadier supply of healthy workers to administer care in times of a crisis, and an overall decrease in the incidence of influenza-related deaths in already compromised inpatients with other medical problems.
Already, the state of New York is hard at work in developing regulatory actions for its public healthcare workers. | LINK
Pfizer’s current research on a potential blockbuster anti-Alzheimer drug is currently back to drawing-board status. According to the pharma company
[T]he drug, called Dimebon, had shown virtually no effect after six months in treating the cognitive decline or behavioral problems associated with Alzheimer’s when compared with a placebo.
Apparently, Wall Street has been watching the results of this Phase I study; the verdict is still out on whether Pfizer will continue to fund the research for this agent — designed to work better and longer at inhibiting some of the most distressing symptoms related to the disease. | LINK

One of the mysteries of Alzheimer dementia (AD) has been the normal function of the amyloid precursor protein (APP); these specialized proteins are concentrated at the points where neurons connect within the brain. Even though the sticky amyloid plaques (which have been viewed as a hallmark sign of AD) result from APP, it seems unlikely that APP exists simply to cause AD. In a recent study, scientists from the U.S. and France show that APP binds to netrin-1, a protein that helps to guide nerves and their connections in the brain, as well as helping nerve cells to survive. When netrin-1 was given to mice that have a gene for AD, their symptoms were reversed, and the sticky amyloid was reduced.
These results suggest that the long-held belief that AD is caused by brain cell damage inflicted by the amyloid plaques may be wrong; instead, it is beginning to appear that the disease stems from an imbalance between the normal making and breaking of connections in the brain, with netrin-1 supporting the connections and the amyloid breaking the connections — both by binding to APP and activating normal cell functional programs. One thing about novel molecular nanoresearch is that it always keeps things interesting. | LINK

In the wake of serious cuts which threaten public universities in Minnesota (largely aimed at the sprawling University of Minnesota system), is now the time to get involved in investing in knowledge capital? The U of M is being blamed for its lack of advancement in the field of bio-tech R&D. A report highlights the problems Minnesota has with maintaining an environment which fosters medical technical advancement and, more importantly in attracting those types of jobs — ones that can sustain a vibrant economy. Although the state is regarded as a pioneer in certain biotech spheres (notably cardiac devices), the report criticized Minnesota as focusing too much on a singular area and remaining stagnant. | LINK | Report PDF LINK
