For older hypertension patients, an unwelcome tradeoff

Medications used by many older people to control their blood pressure also increase the risk of serious fall injuries by 30% to 40% — injuries that have a similar effect on mortality and functional loss as the strokes and heart attacks the blood pressure drugs are meant to prevent — according to a new study by Yale School of Medicine researchers in the Feb. 24 issue of JAMA Internal Medicine.

Clinicians have long assumed that blood pressure medications are safe and effective in all older adults. That is probably true in healthy older adults, but the same might not be true in a more typical population of older adults, who commonly have several other chronic conditions, note the researchers.

Heart attack survival far lower in UK than Sweden

The chance of surviving a heart attack is far lower in the UK than Sweden, according to a major new study published in The Lancet. The startling findings suggest that more than 11,000 lives could have been saved over the past 7 years had UK patients experienced the same care as their Swedish counterparts.

“Our findings are a cause for concern,” says study leader Professor Harry Hemingway, from the Farr Institute of Health Informatics Research, and the National Institute for Cardiovascular Outcomes Research at UCL. “The uptake and use of new technologies and effective treatments recommended in guidelines has been far quicker in Sweden. This has contributed to large differences in the management and outcomes of patients.” (more…)

March of the Pathogens: Parasite Metabolism Can Foretell Disease Ranges under Climate Change

Knowing the temperatures that viruses, bacteria, worms and all other parasites need to grow and survive could help determine the future range of infectious diseases under climate change, according to new research.

Princeton University researchers developed a model that can identify the prospects for nearly any disease-causing parasite as the Earth grows warmer, even if little is known about the organism. Their method calculates how the projected temperature change for an area would alter the creature’s metabolism and life cycle, the researchers report in the journal Ecology Letters. (more…)

USGS Study Tracks Pacific Walrus, Observes Effects of Arctic Sea Ice Loss on Behavior

ANCHORAGE, Alaska — Sparse summer sea ice in the Arctic over the past five years has caused behavioral changes in Pacific walruses according to research published by U.S. Geological Survey and Russian scientists. The effects on the walrus population are unknown.

“The loss of sea ice is the ‘why’ for the change in walrus behavior; the tracking data tells us the ‘where’ in terms of their new forage patterns,” said USGS Director Marcia McNutt. “What awaits to be seen is ‘how much will it matter?'” (more…)

Amazonian Tribal Warfare Sheds Light on Modern Violence, Says MU Anthropologist

Developing a shared sense of global community could help reduce major episodes of violence

In the tribal societies of the Amazon forest, violent conflict accounted for 30 percent of all deaths before contact with Europeans, according to a recent study by University of Missouri anthropologist Robert Walker. Understanding the reasons behind those altercations in the Amazon sheds light on the instinctual motivations that continue to drive human groups to violence, as well as the ways culture influences the intensity and frequency of violence.

“The same reasons – revenge, honor, territory and jealousy over women – that fueled deadly conflicts in the Amazon continue to drive violence in today’s world,” said Walker, lead author and assistant professor of anthropology in MU’s College of Arts and Science. “Humans’ evolutionary history of violent conflict among rival groups goes back to our primate ancestors. It takes a great deal of social training and institutional control to resist our instincts and solve disputes with words instead of weapons. Fortunately, people have developed ways to channel those instincts away from actual deadly conflict. For example, sports and video games often involve the same impulses to defeat a rival group.” (more…)

Yoga Reduces Stress; Now It’s Known Why

UCLA study helps caregivers of people with dementia

Six months ago, researchers at UCLA published a study that showed using a specific type of yoga to engage in a brief, simple daily meditation reduced the stress levels of people who care for those stricken by Alzheimer’s and dementia. Now they know why.

As previously reported, practicing a certain form of chanting yogic meditation for just 12 minutes daily for eight weeks led to a reduction in the biological mechanisms responsible for an increase in the immune system’s inflammation response. Inflammation, if constantly activated, can contribute to a multitude of chronic health problems. (more…)

Income Inequality Leads to More U.S. Deaths, Study Finds

COLUMBUS, Ohio – A new study provides the best evidence to date that higher levels of income inequality in the United States actually lead to more deaths in the country over a period of years.

The findings suggest that income inequality at any one point doesn’t work instantaneously – it begins increasing mortality rates 5 years later, and its influence peaks after 7 years, before fading after 12 years.

“This finding is striking and it supports the argument that income inequality is a public health concern,” said Hui Zheng, author of the study and assistant professor of sociology at Ohio State University. (more…)

The Bright Side of Death: Awareness of Mortality Can Result in Positive Behaviors, Say MU Researchers

COLUMBIA, Mo. — Contemplating death doesn’t necessarily lead to morose despondency, fear, aggression or other negative behaviors, as previous research has suggested. Following a review of dozens of studies, University of Missouri researchers found that thoughts of mortality can lead to decreased militaristic attitudes, better health decisions, increased altruism and helpfulness, and reduced divorce rates.

“According to terror management theory, people deal with their awareness of mortality by upholding cultural beliefs and seeking to become part of something larger and more enduring than themselves, such as nations or religions,” said Jamie Arndt, study co-author and professor of psychological sciences. “Depending on how that manifests itself, positive outcomes can be the result.” (more…)
