Probiotics do not prevent relapse in Crohn's disease patients

2013-08-14
(Press-News.org) Bethesda, MD -- Despite previous data showing beneficial effects, the probiotic Saccharomuces boulardii (S. boulardii) does not prevent clinical relapse in patients with Crohn's disease, according to a new study in Clinical Gastroenterology and Hepatology, the official clinical practice journal of the American Gastroenterological Association.

As more people seek natural or non-drug ways to maintain their health, products containing probiotics have flooded the marketplace. While safe and tolerable, this study discovered that the probiotic S. boulardii does not appear to have any significant beneficial effects for patients with Crohn's disease who are already in remission.

In this randomized, double-blind, placebo-controlled trial, the probiotic yeast S. boulardii was tested as a preventive therapy in patients with moderately severe Crohn's disease who were currently in remission following steroid or salicylate therapies. At the end of the one-year follow-up period, 50 percent of patients had relapsed — 47.5 percent in the S. boulardii group and, similarly, 53.2 percent in the placebo group. Further, the time-to-relapse was not statistically different between patients treated with S. boulardii or placebo.

While this probiotic showed no positive effects for Crohn's disease patients, further studies are needed to determine the potential therapeutic efficacy of probiotics in other forms of IBD, such as ulcerative colitis, and pouchitis.

Probiotics are living microscopic organisms, or microorganisms, that scientific research has shown to benefit an individual's health. S. boulardii, a probiotic made from a strain of yeast and sold in local drug stores or supermarkets in the form of capsules, has been demonstrated to be effective in the treatment of traveler's diarrhea, diarrhea occurring in subjects infected with the human immunodeficiency virus and the prevention of diarrhea associated with antibiotics.

Watermelon juice relieves post-exercise muscle soreness

2013-08-14
Watermelon juice's reputation among athletes is getting scientific support in a new study, which found that juice from the summer favorite fruit can relieve post-exercise muscle soreness. The report in ACS' Journal of Agricultural and Food Chemistry attributes watermelon's effects to the amino acid L-citrulline. Encarna Aguayo and colleagues cite past research on watermelon juice's antioxidant properties and its potential to increase muscle protein and enhance athletic performance. But scientists had yet to explore the effectiveness of watermelon juice drinks enriched ...

Cattle can be a source of MRSA in people, scientists find

2013-08-14
A type of MRSA found in humans originated in cattle at least 40 years ago, new research has found. The study provides clear evidence that livestock were the original source of an MRSA strain which is now widespread in people. Researchers studied the genetic make-up of more than 40 strains of a bacterium -- called Staphylococcus aureus -- that can build up antibiotic resistance to develop into MRSA. At least two genetic subtypes of the bacterium, which have become endemic in people, have been traced back to cattle by the scientists, who are based at The Roslin Institute ...

A new sense of urgency for energy cane and other energy crops

2013-08-14
"Energy cane" may sound like a trendy sports drink, but it actually is among a new generation of energy crops that could yield up to 5 times more ethanol per acre than corn. They are the topic of the cover story in this week's Chemical & Engineering News. C&EN is the weekly newsmagazine of the American Chemical Society, the world's largest scientific society. C&EN Senior Editor Melody M. Bomgardner explains that energy cane is a new, high-fiber variety of sugarcane now being grown in California's Imperial Valley. Scientists bred it specifically as an "energy crop," a ...

Lymph nodes with location memory

2013-08-14
This news release is available in German. Regulatory T cells (or "Tregs" for short) play a central role in the human immune system: They guide all of the other immune cells and make sure they are tolerant of the body's own cells and harmless foreign substances. How Tregs become Tregs in the first place has been only incompletely understood -- until now. Scientists at the Helmholtz Centre for Infection Research (HZI) in Braunschweig, Germany, along with their colleagues at the Hannover Medical School (MHH) have recently gleaned important new insights into the workings ...

Pilot study finds ER patients drinking high-octane beer

2013-08-14
Five beer brands – Budweiser, Steel Reserve, Colt 45, Bud Ice and Bud Light – were consumed in the highest quantities by emergency room patients, according to a new pilot study from researchers at The Center on Alcohol Marketing and Youth (CAMY) at the Johns Hopkins Bloomberg School of Public Health. Three of these are "malt liquors" with higher alcohol content than regular beer. The pilot study, published by Substance Use and Misuse, is the first study of its kind to assess alcohol consumption by brand and type from patients reporting to the emergency department with ...

A genetic answer to the Alzheimer's riddle?

2013-08-14
LEXINGTON, Ky. (Aug. 14, 2013) — What if we could pinpoint a hereditary cause for Alzheimer's, and intervene to reduce the risk of the disease? We may be closer to that goal, thanks to a team at the University of Kentucky. Researchers affiliated with the UK Sanders-Brown Center on Aging have completed new work in Alzheimer's genetics; the research is detailed in a paper published today in the Journal of Neuroscience. Emerging evidence indicates that, much like in the case of high cholesterol, some Alzheimer's disease risk is inherited while the remainder is environmental. ...

Chemophobia shouldn't be on the menu

2013-08-14
When it comes to what's for dinner – or breakfast and lunch for that matter-- many people suffer from chemophobia, an irrational fear of natural and synthetic chemicals that pose no risk to our health, a Dartmouth study finds. Chemistry Professor Gordon Gribble, whose paper appears in the journal Food Security, argues that low doses of chemicals in modern food are inherent, typically harmless and often highly beneficial. He says most people don't know they are routinely exposed to a host of compounds in non-toxic concentrations in what they eat and drink each day. Even ...

Virtual adviser helps older Latino adults get more exercise, Stanford researcher says

2013-08-14
STANFORD, Calif. — When it comes to getting motivated to exercise and do things that are good for our health, sometimes all it takes is a little help from our friends. This was certainly the case for a group of older, Latino adults in Northern California: They benefited from the advice and encouragement of a virtual friend — a physical-activity adviser named Carmen, a new study reports. Individuals who participated in an exercise program guided by the virtual adviser had an eight-fold increase in walking compared with those who did not, according to the study, published ...

Rice U. biophysicists zoom in on pore-forming toxin

2013-08-14
HOUSTON -- (Aug. 14, 2013) -- A new study by Rice University biophysicists offers the most comprehensive picture yet of the molecular-level action of melittin, the principal toxin in bee venom. The research could aid in the development of new drugs that use a similar mechanism as melittin's to attack cancer and bacteria. The study appears this week in the Proceedings of the National Academy of Sciences. Melittin does its damage by penetrating the outer walls of cells and opening pores that allow the contents of the cell to escape. At low concentrations, melittin forms ...

Ethical issues are often not addressed in national clinical practice guidelines for dementia

2013-08-14
Twelve national dementia clinical practice guidelines included only half of 31 ethical issues the authors had identified as important in patient care, finds a study by Daniel Strech, of Hannover Medical School, Hannover, Germany, and colleagues, published in this week's issue of PLOS Medicine. The authors identified current national clinical practice guidelines for dementia care published in English or German. They had previously systematically reviewed ethical issues in dementia care and they used thematic text analysis to assess whether and how the ethical issues were ...
