It has been known for some time that many factors beyond health care influence health. More recently, networks of real estate developers, banks, city planners, and non-profit groups have been collaborating with public health and related health-focused institutions to improve health. A key goal is to invest in low-income communities by affording them access to nutritious food, green spaces, and other healthful attributes.
As part of its ongoing efforts to ensure safe, effective and appropriate medical imaging, the American College of Radiology has joined the ABIM Foundation and eight other medical specialty societies in Choosing Wisely. The new campaign promotes wise choices by physicians and patients to improve health outcomes, avoid unnecessary interventions and make efficient use of healthcare dollars.
The ACR will develop a list of five things to reduce unnecessary imaging exams ordered by physicians and improve quality of care. The list names imaging exams whose necessity should be discussed before being ordered. The list also equips providers with steps to help ensure safe, appropriate use of scans.
“Medical imaging exams are a perfect fit for Choosing Wisely. Scans lower healthcare costs by replacing more invasive surgeries and allowing for shorter hospital stays. Although imaging use is down significantly since 2008 and Medicare spending on imaging is the same as in 2004, opportunities remain to ensure appropriate ordering of scans. As greater access to imaging is directly tied to increased life expectancy, ACR will identify areas where care can be improved without restricting patient access,” said John A. Patti, MD, FACR, chair of the ACR Board of Chancellors……
The ACR list, and those of other Choosing Wisely partners, will be released in April 2012. To learn more, visit ChoosingWisely.org.

WASHINGTON, DC — A study in the December issue of the American Sociological Review has brought new understanding as to why death rates for less educated middle aged adults are much higher than for their more educated peers despite increased awareness and treatments aimed at reducing health disparities.

The author comes across as knowledgeable, reflective, willing to learn from others, grateful for financial support, and driven to share his knowledge for the benefit of all]
For decades, data has shown that middle aged adults with low education levels—that is high school or less—are twice as likely to die as those with higher education levels. Professor Richard Miech, of the Department of Health and Behavioral Sciences at the University of Colorado Denver’s College of Liberal Arts and Sciences, and his colleagues wanted to better understand why this persists. They found that as new causes of death emerge, people with lower education levels are slower to respond with behavioral changes, creating a moving target that often remains a step ahead of prevention. Almost all causes of death that are on the increase are fueled by high rates of mortality among people with lower education, a trend that counters any progress made in the reduction of today’s health disparities….

A father in Louisiana bludgeoned and beheaded his disabled 7-year-old son last August because he no longer wanted to care for the boy. For most people, such a heinous act is unconscionable.
But it may be that a person can become callous enough to commit human atrocities because of a failure in the part of the brain that’s critical for social interaction. A new study by researchers at Duke University and Princeton University suggests this function may disengage when people encounter others they consider disgusting, thus “dehumanizing” their victims by failing to acknowledge they have thoughts and feelings.
This shortcoming also may help explain how propaganda depicting Tutsi in Rwanda as cockroaches and Hitler’s classification of Jews in Nazi Germany as vermin contributed to torture and genocide, the study said.
“When we encounter a person, we usually infer something about their minds. Sometimes, we fail to do this, opening up the possibility that we do not perceive the person as fully human,” said lead author Lasana Harris, an assistant professor in Duke University’s Department of Psychology & Neuroscience and Center for Cognitive Neuroscience. Harris co-authored the study with Susan Fiske, a professor of psychology at Princeton University.
Social neuroscience has shown through MRI studies that people normally activate a network in the brain related to social cognition — thoughts, feelings, empathy, for example — when viewing pictures of others or thinking about their thoughts. But when participants in this study were asked to consider images of people they considered drug addicts, homeless people, and others they deemed low on the social ladder, parts of this network failed to engage.
What’s especially striking, the researchers said, is that people will easily ascribe social cognition — a belief in an internal life such as emotions — to animals and cars, but will avoid making eye contact with the homeless panhandler in the subway.
“We need to think about other people’s experience,” Fiske said. “It’s what makes them fully human to us.”…

There are probably at least 500 medically useful chemicals awaiting discovery in plant species whose chemical constituents have not yet been evaluated for their potential to cure or treat disease, according to a new analysis by a New York Botanical Garden scientist who has more than 15 years of experience in collecting plants for natural-products discovery programs.
Currently, 135 drugs on the market are derived directly from plants; the analysis indicates that at least three times as many disease-fighting substances have yet to be found that could be developed into drugs or used as the basis for further drug research.
“Clearly, plant diversity has not been exhausted, and there is still great potential in the plant world,” said James S. Miller, Ph.D., Dean and Vice President for Science at the Botanical Garden.
Dr. Miller’s analysis, “The Discovery of Medicines from Plants: A Current Biological Perspective,” is published in the December issue of the peer-reviewed journal Economic Botany. …
Dr. Miller argues that one possible explanation for the low yield is the relatively crude way in which plant extracts were tested for their pharmaceutical potential. Plants may contain as many as 500 to 800 different chemical compounds, but the screening programs of the late 20th century used extracts made from a whole plant or at best extracts that contained many hundreds of compounds.
Under those circumstances, one compound may interfere with the action of another, or the amount of one compound may be too small to register in a mix of hundreds of chemicals.
To correct this problem, new technologies now allow researchers to separate complex mixtures of natural products into a “library” of relatively pure compounds that can be tested individually. A 2002 study demonstrated that testing such libraries dramatically improves discovery rates. …..

Antibacterial Drugs and the Risk of Community-Associated Methicillin-Resistant Staphylococcus aureus in Children
Antibacterial Drugs and the Risk of Community-Associated Methicillin-Resistant Staphylococcus aureus in ChildrenSource: Archives of Pediatrics & Adolescent Medicine
To investigate in children the association between antibacterial drugs and subsequent diagnosis of methicillin-resistant Staphylococcus aureus (MRSA) in the community.
Population-based case-control study in children 1 to 19 years of age.
Primary care, General Practice Research Database, United Kingdom, 1994-2007.
Cases were children who had MRSA diagnosed as outpatients, and controls were individually matched on age and practice, with the matched case’s diagnosis date as the index date for both.
Antibacterial agents prescribed 180 to 30 days prior to the index date, excluding prescriptions 30 days before the index date to prevent protopathic bias.
Rate ratios (RRs) estimated from the odds ratios of exposure in cases compared with controls using conditional logistic regression, adjusted for comorbid conditions, other prescription drug use, and hospitalization.
The rate of MRSA was 4.5 per 100 000 per year. Of 297 cases and 9357 controls, 52.5% and 13.6%, respectively, received antibacterial drug prescriptions during the 150-day exposure window. The adjusted RR with any antibacterial drug was 3.5 (95% confidence interval [CI], 2.6-4.8). The RRs increased with the number of prescriptions (2.2 [95% CI, 1.5-3.2], 3.3 [95% CI, 1.9-5.6], 11.0 [95% CI, 5.6-21.6], and 18.2 [95% CI, 9.4-35.4] for 1, 2, 3, and 4 prescriptions, respectively). The RR was particularly elevated for quinolones at 14.8 (95% CI, 3.9-55.8), with wide variation among antibacterial classes.
While close to half of children were diagnosed as having MRSA in the community without prior antibacterial drugs, such agents are associated with a dose-dependent increased risk, concordant with findings in adults.
