More than half a million adults in California seriously thought about committing suicide during the previous year, according to a new study from the UCLA Center for Health Policy Research.
The study, which uses data from the 2009 California Health Interview Survey (CHIS), is the first by the center to focus on suicide ideation.
In California, suicide is the 10th leading cause of death, the researchers noted. An average of nine deaths by suicide occur each day in the state. (more…)
TORONTO, ON – Elderly people taking anti-hypertensive drugs are at a 43 per cent increased risk of having a hip fracture in the first 45 days of treatment, according to research conducted by family medicine Assistant Professor Dr. Debra Butt. A member of the Department of Family and Community Medicine at the University of Toronto and a family physician affiliated with The Scarborough Hospital, Dr. Butt’s study was published on November 19, 2012 in Archives of Internal Medicine. The study examined data from health care administrative databases in Ontario, looking at records from 2000 to 2009 for community-dwelling hypertensive patients with a mean age of 80.8 years.
There are serious consequences to a hip fracture for the elderly. In the first year of a hip fracture there is a higher mortality rate than is seen for many chronic diseases. Those who recover often lose their independence due to reduced mobility, which can result in depression and overall decreased quality of life. (more…)
COLUMBIA, Mo. — Saving bar patrons’ time on their commute home could save lives. A pair of studies by University of Missouri psychologists found that people who reported drinking and driving also exhibited “urgency,” or a lack of emotional self-control, especially while drinking. This suggests that some people when intoxicated may be more likely to choose the convenience of driving themselves home instead of waiting for a taxi, said Denis McCarthy, associate professor of psychology at MU.
“Our study correlated urgency, a specific type of impulsivity, to drinking and driving,” McCarthy said. “Individuals with a high degree of urgency tend to act impulsively when they are in both positive and negative emotional states. By looking at personality traits that correlate with drinking and driving, we can help people understand how their personalities might incline them to choose the risk of driving after drinking. Once a person knows this, they can decide to take extra care to moderate their drinking or be prepared to call a cab, hop on a bus or ask a designated driver for help.” (more…)
Health practitioners should use behavior-change tactics so patients take medications as prescribed
COLUMBIA, Mo. – Nearly half of patients taking medications for chronic conditions do not strictly follow their prescribed medication regimens. Failure to use medications as directed increases patients’ risk for side effects, hospitalizations, reduced quality of life and shortened lifespans. Now, a University of Missouri gerontological nursing expert says patients’ poor adherence to prescribed medication regimens is connected to their beliefs about the necessity of prescriptions and concerns about long-term effects and dependency.
MU Assistant Professor Todd Ruppar found that patients’ beliefs about the causes of high blood pressure and the effectiveness of treatment alternatives significantly affected their likelihood of faithfully following prescribed medication regimens. In his pilot study, Ruppar focused on older patients’ adherence to medication treatments that control high blood pressure, a condition that affects nearly 70 million adults in the U.S. and can lead to heart disease and stroke.

For women of mixed racial or ethnic backgrounds, a new method for measuring bone health may improve the odds of correctly diagnosing their risk of osteoporosis and bone fractures, according to a UCLA-led study.
Currently, assessing osteoporosis and the risk of fractures from small accidents like falls requires a bone density scan. But because these scans don’t provide other relevant fracture-related information, such as bone size and the amount of force a bone is subjected to during a fall, each patient’s bone density is examined against a national database of people with the same age and race or ethnicity.

Berkeley Lab research could lead to new ways to ID women who have higher risk of breast cancer from low-dose radiation
Scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have identified tissue mechanisms that may influence a woman’s susceptibility or resistance to breast cancer after exposure to low-dose ionizing radiation, such as the levels used in full-body CT scans and radiotherapy.
The research could lead to new ways to identify women who have higher or lower risks of breast cancer from low-dose radiation. Such a predictive tool could help guide the treatment of cancer patients who may be better served by non-radiation therapies. (more…)
Playing football (soccer) could be the best way for people with high blood pressure, known as hypertension, to improve their fitness, normalise their blood pressure and reduce their risk of stroke, according to research published today (Monday 15 October 2012) in the journal Medicine and Science in Sports and Exercise.
Research from Universities of Exeter and Copenhagen, and Gentofte University Hospital in Denmark suggests football training prevents cardiovascular disease in middle-aged men with hypertension and is more effective than healthy lifestyle advice currently prescribed by GPs.
After six months of football training, three out of four men in this study had blood pressure within the normal, healthy range. (more…)
Blanket bogs, which provide vital habitats for a unique range of plants, birds, small mammals, reptiles and amphibians, are at risk of declining as a result of climate change.
Research by the Universities of Exeter and Bristol in the UK and Macquarie University in Australia, published in the journal Nature Climate Change, shows for the first time how rising temperatures will threaten these sensitive ecosystems.
The study highlights the urgency of developing a plan to protect these important habitats.
Found in wet, coastal areas of high latitude regions, blanket bogs cover around 700,000 hectares of land in the UK, much of it designated as a Site of Special Scientific Interest (SSSI). Blanket bogs are found in the north and west of the UK, extending from Devon in the south to Shetland in the north, and it has been estimated that 10 to15 per cent of the world’s blanket bog occurs in Britain. As well as being crucial in supporting wildlife, blanket bogs also capture and store large amounts of carbon, helping to mitigate against climate change, and reduce the risk of flooding, by slowing down water flow. With some blanket peat being over 9,000 years old, they also hold historically-significant archaeological material. (more…)
