Road losses add up, taxing amphibians and other animals
When frogs hit the road, many croak. Researchers found more than 65 animal species killed along a short stretch of roads in a Midwestern county. Nearly 95 percent of the total dead were frogs and other amphibians, suggesting that road-related death, or road-kill, possibly contributes to their worldwide decline, a trend that has concerned and... view more...

Decline of house sparrows due to lack of overwinter food
The decline of the house sparrow in rural areas of Britain over the past two decades has possible occurred because of reduced food supplies, leading to localised extinctions, according to a report by Oxford zoologists published tomorrow [29 August 2002] in Nature. view more (2002-08-28)

Brain function and negative thinking linked to late-onset depression
Late-onset depression, which first emerges in people aged 60 and over, is linked to a decline in the brain's executive functions that leads to repetitive, negative thought patterns a new study reveals. view more (2006-06-26)
Ace Inhibitors Could Slow Muscle Decline (p 926)
Angiotensin-converting enzyme (ACE) inhibitors, a class of drugs used to lower blood pressure, could also be protective against the decline in muscle strength in elderly women suggest authors of a study in this week's issue of THE LANCET. ACE inhibitors are known to prevent the decline in physical function in patients with congestive heart failure... view more... (2002-03-13)
Eating fish associated with slower cognitive decline
Consuming fish at least once a week was associated with a 10 percent per year slower rate of cognitive decline in elderly people, according to a new study posted online today from Archives of Neurology, one of the JAMA/Archives journals. The study will be published in the December print edition of the journal. view more (2005-10-11)
Beta carotene slows decline in lung power associated with ageing
Beta carotene, a precursor to vitamin A, slows the decline in lung power associated with ageing, reveals research in Thorax. view more (2006-03-23)
All species are not created equal when assessing the impacts of species loss on ecosystems
Numerous studies have shown that when species are randomly lost from communities, ecosystem function declines. But such patterns of species loss do not reflect those in natural communities where major drivers of change, such as stress and disturbance, cause preferential loss of rare and uncommon species. In the June issue of Ecology Letters, Smith... view more... (2003-05-22)
Study: Fountain of youth for your heart?
An age-related decline in heart function is a risk factor for heart disease in the elderly. While many factors contribute to a progressive age-related decline in heart function, alterations in the types of fuels the heart uses to produce energy also play important roles. view more (2007-11-05)
Recession cuts many, not all plastic surgery procedures
Showing sensitivity to weaknesses in the U.S. economy, plastic surgery was not spared from the recession's grasp. According to the newest national procedural statistics report from the American Society of Plastic Surgeons (ASPS), in 2008, doctors performed over 12 million cosmetic plastic surgery procedures - encompassing both surgical and... view more...

Food shortages threaten Antarctic wildlife
Antarctic whales, seals and penguins could be threatened by food shortages in the Southern Ocean. Numbers of Antarctic krill (Euphausia superba), a shrimp-like crustacean at the heart of the food chain, are declining. The most likely explanation is a dramatic decline in sea-ice. The results are published this week in the journal Nature. view more (2004-11-01)
Relationship between statins and cognitive decline more complex than thought
Previous explorations of a link between statins, a cholesterol lowering medication, and cognitive decline have produced inconsistent results. view more (2007-11-06)
Bypass not to blame for heart patients' mental decline
Heart patients often experience lasting problems with memory, language, and other cognitive skills after bypass surgery. However, these problems aren't caused by the surgery itself or the pump used to replace heart function during surgery, a new study by Johns Hopkins researchers suggests. view more (2008-05-20)

IS THE AMERICAN LEADERSHIP IN CLINICAL MEDICINE RESEARCH DECLINING? A CITATION ANALYSIS
Citation analysis is a powerful measurement of the scientific impact of medical papers. All papers which were published in journals of general and internal medicine (such as the Lancet or the New England Journal of Medicine), the citations which attracted and their impact (citations divided by number of papers) were analyzed according to country... view more...

Poor sleep associated with cognitive decline in elderly women
Women who experienced cognitive decline over a 13 to 15 year period after age 65 were more likely to sleep poorly than women whose cognition did not decline. view more (2007-07-17)
Decline in lung function increases risk of death from all causes
Reduced ability of the lungs to work properly - a process accelerated by smoking - increases the risk of death from all causes, shows research in Thorax. But even giving up for a while, halts the decline, and can reduce the risk of death from all causes by around 20 per cent, the study shows. The research involved a long term study between 1959... view more... (2001-08-20)
Stroke patients may be more likely to experience memory decline
A history of stroke may be associated with progressive memory difficulties in patients without dementia or cognitive impairment. view more (2006-04-11)
Impaired kidney function linked to cognitive decline in elderly
A new study published in the medical journal Neurology suggests that impaired kidney function is a risk factor for cognitive decline in old age. view more (2009-09-29)
