Laser technique has implications for detecting microbial life forms in Martian ice

New Rochelle, NY, October 1, 2009–An innovative technique called L.I.F.E. imaging used successfully to detect bacteria in frozen Antarctic lakes could have exciting implications for demonstrating signs of life in the polar regions of Mars, according to an article published in the current issue of Astrobiology, a peer-reviewed journal published by Mary Ann Liebert, Inc. (www.liebertpub.com). The article is available free online at www.liebertpub.com/ast

Treatment of severe burn injuries

Almost three quarters of patients with extensive burns die of the consequences of a severe infection. In the current edition of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2009; 106[38]: 607-13), Timo A. Spanholtz of the Cologne-Merheim Burn Center and his coauthors discuss the acute therapy and follow-up care of burn disease.

Natural selection favors the noble...on the molecular level, anyway

Cheaters may prosper in the short term, but over time they seem doomed to fail, at least in the microscopic world of amoebas where natural selection favors the noble.

But why? Shouldn't "survival of the fittest" give the sneaky cheaters an edge? Not necessarily, as it turns out amoebas that cooperate for the benefit of all – and even die for the cause – bring their own genetic weapons to the fight.

Kidneys from deceased donors with acute renal failure expand donor pool

WINSTON-SALEM, N.C. – Kidneys recovered from deceased donors with acute renal failure (ARF) – once deemed unusable for transplant – appear to work just as well as kidneys transplanted from deceased donors who do not develop kidney problems prior to organ donation, according to a new study by researchers at Wake Forest University Baptist Medical Center.

Wrist fracture patients less likely to be evaluated for osteoporosis

ROSEMONT, Ill -- A study published in the October 2009 issue of the Journal of Bone and Joint Surgery suggests a disconnect between the way wrist-fracture patients and those with a spine or hip fracture are managed and evaluated. The study, conducted in 2007 among 97 percent of the women in Korea, reviewed the incidence of fractures around the hip, spine, and wrist in female patients age 50 and older and the prescription frequencies of bone density scans for osteoporosis, along with the use of medications for its treatment.

Oxidized form of a common vitamin may bring relief for ulcerative colitis

Here's another reason why you should take your vitamins. A new research report appearing in the October 2009 print issue of the Journal of Leukocyte Biology (http://www.jleukbio.org) suggests that retinoic acid, the oxidized form of vitamin A, could be a beneficial treatment for people suffering from ulcerative colitis and other irritable bowel diseases. Specifically they found that retinoic acid helps suppress out-of-control inflammation, which is a hallmark of active ulcerative colitis.

Combination of PET/CT tests can expedite diagnosis of lung cancer in a fast-track setting

Research published in the October 2009 issue of the Journal of Thoracic Oncology has found an effective combination of positron emission tomography (PET)/computed tomography (CT) (PET/CT) tests to diagnose lung cancer in a "fast-tracked" outpatient setting. This novel approach to the diagnosis of lung cancer demonstrated a high level of sensitivity (97%) and accuracy (82%). The fast track model tests patients for lung cancer over the course of one day and could expedite identification and treatment of the disease.

Lung cancer risk increases with expression of specific genes

AURORA, COLO – A recent study published in the October 2009 issue of the Journal of Thoracic Oncology determined that variations of specific genetic markers identified in previous research, or SNPs, may indicate a greater lung cancer risk in African Americans than in whites. The genes CHRNA3 and CHRNA5 may contribute to lung cancer risk due directly or through their association with nicotine dependence. Although their presence is less frequent in African Americans, the risk for lung cancer may be greater when present.

PET imaging aids doctors in effort to catch endometrial carcinoma early on

Reston, Va.—A promising new molecular imaging technique may provide physicians and patients with a noninvasive way to learn more information about a type of cancer of the uterus lining called "endometrial carcinoma"—one of the most common malignant female tumors. This research was presented in a study published in the October issue of The Journal of Nuclear Medicine.

Ulcerative colitis treatment reduces need for surgery by almost half

ROCHESTER, Minn -- A new study led by Mayo Clinic researchers has found that ulcerative colitis patients had a 41 percent reduction in colectomy after a year when treated with infliximab, according to a study published in the October 2009 issue of Gastroenterology.

Amitriptyline and placebo are equally effective pain relievers for children, study finds

Bethesda, MD (Oct. 1, 2009) — When used "off-label," the antidepressant amitriptyline works just as well as placebo in treating pain-predominant gastrointestinal disorders in children, according to a new study in Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute.

More research needed to assess benefits of platelet-rich plasma, doctors say

ROSEMONT, Ill. – Platelet -rich plasma (PRP) is currently used as an alternative treatment method for several common orthopaedic-related sports medicine conditions. According to a new study in the October issue of the Journal of the American Academy of Orthopaedic Surgeons (JAAOS), early outcomes of PRP appear promising; however, larger clinical studies are still needed to determine the benefits of its use.

Prenatal exposure to H1N1 increases chances of heart disease?

People exposed to a H1NI strain of influenza A while in utero were significantly more likely to have cardiovascular disease later in life, reveals a new study to be published in Journal of Developmental Origins of Health and Disease on Oct. 1.

"Our point is that during pregnancy, even mild sickness from flu could affect development with longer consequences," said senior author Caleb Finch, USC professor of gerontology and biological sciences.

Keyboards and mice can harbor hospital infections

Although hospital computer equipment can act as a reservoir for pathogenic organisms, including MRSA, researchers writing in the open access journal BMC Infectious Diseases found that bacterial contamination rates from computer equipment were low, possibly as the result of good hand hygiene.

Children found to be most at risk from malaria

Insecticide treated mosquito nets reduce the chances of developing life-threatening malaria in Africa, however recent research shows that older children are the least well protected by nets in the community. The research, published in the open access journal BMC Public Health, has found that parents and their young children were much more likely to have malaria nets than older children.
