Rethink fears the credit crunch will lead to more people seeing their GPs
The fallout from the economic downturn could be a significant threat to mental health, according to a survey.

House repossession was rated as the event most likely to cause mental health problems, ahead of redundancy, or finding out about infertility.

Charity Rethink called for action to prevent a "mental health disaster".


Comment: Given the changes in bankruptcy laws in the US (among other things), one would think that the pervasive mental breakdown of the population was the goal. Scared and cofused people are so much easier to control.

New Light On Link Between Snoring And Cognitive Deficits In Children


Science Daily
Fri, 10 Oct 2008 18:38 UTC
About two-thirds of children with sleep-disordered breathing (SDB) - snoring or obstructive sleep apnea (OSA) - have some degree of cognitive deficit, but the severity of the cognitive deficit has been notoriously difficult to correlate to the severity of the SDB, suggesting that other important issues may be at play, or that the right factors were simply not being measured.

A new study that will be published in the first issue for November of the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine opens the door to understanding the complex relationship between sleep, breathing and brain function in a whole new way.

"A history of snoring is a predictor for cognitive deficit in children with SDB," said principle investigator Raouf Amin, M.D., professor of pediatrics and the director of the Division of Pulmonary Medicine at Cincinnati Children's Hospital Medical Center. "However, the frequency of apnea events during sleep does not predict cognitive deficit and does not correlate with the degree of cognitive deficit. Such a paradox raised the question of whether there are some variables that we do not traditionally measure in the sleep laboratory that might modify the effect of SDB on cognition."

Probiotics And Effectiveness In Irritable Bowel Syndrome


Science Daily
Fri, 10 Oct 2008 18:33 UTC
Several studies presented at the American College of Gastroenterology's 73rd Annual Scientific Meeting in Orlando highlight the safety and efficacy of probiotics in improving symptoms and normalizing bowel movement frequency in patients suffering from constipation or diarrhea related to Irritable Bowel Syndrome (IBS).

A systematic review of the efficacy of probiotics in IBS that included 19 randomized controlled trials in 1,628 IBS patients found that "probiotics are effective in IBS, but we do not have enough information to be sure whether there is one probiotic that is particularly effective or whether combinations of probiotics are required," according to Dr. Paul Moayyedi, the study's lead researcher. Moayyedi and co-investigators at Mayo Clinic in Jacksonville, FL and Rochester, MN; McMaster University in Ontario, Canada; University College in Cork, Ireland and Montefiore Medical Center in New York City, conducted this meta-analysis presented at the ACG Annual Scientific Meeting in Orlando.

Multi-Strain Probiotic for IBS Patients with Diarrhea

Dr. Gerald Friedman of The Mount Sinai School of Medicine in New York and co-investigator Greg Biancone conducted a multi-center analysis to determine if a multi-strain probiotic was effective in reducing the frequency of diarrhea in 84 IBS patients (IBS-D). In this small study, a multi-strain probiotic administered daily for 28 days normalized bowel habits in IBS patients compared to those who received the placebo. The average number of daily diarrheal episodes in the probiotic group significantly decreased from day 1 to day 28 compared to slight decreases in the placebo group during the same period.

The Pepperoni Pizza Hypothesis


Science Daily
Thu, 09 Oct 2008 17:39 UTC
What's the worst that could happen after eating a slice of pepperoni pizza? A little heartburn, for most people.
But for up to a million women in the U.S., enjoying that piece of pizza has painful consequences. They have a chronic bladder condition that causes pelvic pain. Spicy food -- as well as citrus, caffeine, tomatoes and alcohol-- can cause a flare in their symptoms and intensify the pain. It was thought that the spike in their symptoms was triggered when digesting the foods produced chemicals in the urine that irritated the bladder.

However, researchers from Northwestern University's Feinberg School of Medicine believe the symptoms -- pain and an urgent need to frequently urinate -- are actually being provoked by a surprise perpetrator. Applying their recent animal study to humans, the scientists believe the colon, irritated by the spicy food, is to blame.

Honey Helps To Heal Wounds, Review Suggests


Science Daily
Thu, 09 Oct 2008 17:35 UTC
Honey may reduce healing times in patients suffering mild to moderate burn wounds. A systematic review by Cochrane Researchers concluded that honey might be useful as an alternative to traditional wound dressings in treating burns.

"We're treating these results with caution, but it looks like honey can help speed up healing in some burns," says lead researcher Dr Andrew Jull, of the Clinical Trials Research Unit at the University of Auckland, New Zealand.

Honey has been used in wound treatment since ancient times. The mechanism of action is unclear. While honey may help the body remove dead tissue and provide a favourable environment for the growth of new, healthy tissue, current interest in medicinal honey focuses largely on its antibacterial effects.

Burn Treatment Cream May Delay Healing


Science Daily
Thu, 09 Oct 2008 17:31 UTC
A cream commonly used to treat burns may actually delay healing. In addition, despite the wide range of wound dressings available for burns, there is no consensus on the most effective alternative treatment, say Cochrane Researchers who carried out a systematic review of existing data.

Increased understanding of the wound healing process means that there are now a large number of different ways to treat burns. Films, gels, artificial skins and fibre dressings may all help to heal wounds, but doctors still often turn to traditional gauze dressings, as well as silver sulphadiazine (SSD) cream. Healthcare providers have used SSD cream since the 1960s to minimize the risk of burns becoming infected, although concerns have recently been raised about its toxic effects on skin cells.

The Cochrane Team who carried out the research found 26 relevant trials. Although each trial was relatively small they concluded that SSD cream increases the time taken for a wound to heal, as well as increasing the number of dressing applications required.

Circadian Clock May Be Critical For Remembering What You Learn


Science Daily
Thu, 09 Oct 2008 17:26 UTC
The circadian rhythm that quietly pulses inside us all, guiding our daily cycle from sleep to wakefulness and back to sleep again, may be doing much more than just that simple metronomic task, according to Stanford researchers.

Working with Siberian hamsters, biologist Norman Ruby has shown that having a functioning circadian system is critical to the hamsters' ability to remember what they have learned. Without it, he said, "They can't remember anything."

Though not known for their academic prowess, Siberian hamsters nonetheless normally develop what amounts to street smarts about their environment, as do all animals. But hamsters whose circadian system was disabled by a new technique Ruby and his colleagues developed consistently failed to demonstrate the same evidence of remembering their environment as hamsters with normally functioning circadian systems.

Psychologists Show Experience May Be The Best Teacher For Infants


Science Daily
Thu, 09 Oct 2008 17:23 UTC
There's a lot of truth in the old proverb "experience is the best teacher," and apparently it even applies to 10-month-old infants.

Researchers have found that infants who had an opportunity to use a plastic cane to get an out-of-reach toy were better able to understand the goal of another person's use of a similar tool than were infants who had previously only watched an adult use a cane to retrieve a toy.

"Acting on the world is one way infants learn about the world, and only recently have there been studies showing that active, hands-on experience is a more effective way of learning than watching. This study indicates that there is a benefit to actual hands-on experience early in human development," said, Jessica Sommerville, a University of Washington assistant professor of psychology and lead author of a study published in the current issue of the journal Developmental Psychology.

Chronic Kidney Disease Increased Sharply In The United States In Past Decade


Science Daily
Thu, 09 Oct 2008 17:18 UTC
A 30 percent increase in chronic kidney disease over the past decade has prompted the U.S. Renal Data System (USRDS) to issue for the first time a separate report documenting the magnitude of the disease, which affects an estimated 27 million Americans and accounts for more than 24 percent of Medicare costs.

"NIDDK's annual analysis and publication of data on kidney disease in the United States is essential in quantifying public health trends, guiding funding priorities, and designing targeted kidney research programs," said NIH Director Elias A. Zerhouni, M.D. "The major focus on chronic kidney disease in this year's report acknowledges that this disorder is a growing public health issue deserving of wider public awareness and intensified scientific investigation."

Using data from multiple sources, the USRDS has created a new handbook of information that can be used by researchers, government officials, health program planners, and others to develop research goals, assess public health needs, set program priorities, and inform policymakers and the public. USRDS research depends on collaborations with other agencies of the U.S. Department of Health and Human Services, especially the Centers for Medicare and Medicaid Services, the Health Resources and Services Administration, and the Centers for Disease Control and Prevention. Patient registries for other countries also contribute data for analyses.
