Tool to better screen, treat aneurysm patients

Tool to better screen, treat aneurysm patients

New research by an international consortium, including a researcher from Lawrence Livermore National Laboratory, may help physicians better understand the chronological development of a brain aneurysm. Using radiocarbon dating to date samples of ruptured and unruptured cerebral aneurysm (CA) tissue, the team, led by neurosurgeon Nima Etminan, found that the main structural constituent and protein — collagen type I — in cerebral aneurysms is distinctly younger than once thought Continue reading

Rare skin cancer on palms, soles more likely to come back compared to other melanomas

Rare skin cancer on palms, soles more likely to come back compared to other melanomas

A rare type of melanoma that disproportionately attacks the palms and soles and under the nails of Asians, African-Americans, and Hispanics, who all generally have darker skins, and is not caused by sun exposure, is almost twice as likely to recur than other similar types of skin cancer, according to results of a study in 244 patients. The finding about acral lentiginous melanoma, as the potentially deadly cancer is known, is part of a study to be presented May 31 by researchers at the Perlmutter Cancer Center of NYU Langone at the annual meeting of the American Society of Clinical Oncology in Chicago Continue reading

In Africa, STI testing could boost HIV prevention

In Africa, STI testing could boost HIV prevention

To maximize HIV prevention efforts in South Africa and perhaps the broader region, public health officials should consider testing for other sexually transmitted infections when they test for HIV, according to a new paper in the journal Sexually Transmitted Infections . STIs can make HIV easier to transmit even after antiretroviral therapy has begun, so rooting out STI co-infections in patients should improve HIV prevention. Continue reading

Learning early in life may help keep brain cells alive: Brain cells survive in young who master a task

Learning early in life may help keep brain cells alive: Brain cells survive in young who master a task

Using your brain — particularly during adolescence — may help brain cells survive and could impact how the brain functions after puberty. According to a recently published study in Frontiers in Neuroscience , Rutgers behavioral and systems neuroscientist Tracey Shors, who co-authored the study, found that the newborn brain cells in young rats that were successful at learning survived while the same brain cells in animals that didn’t master the task died quickly. “In those that didn’t learn, three weeks after the new brain cells were made, nearly one-half of them were no longer there,” said Shors, professor in the Department of Psychology and Center for Collaborative Neuroscience at Rutgers.

New glasses may increase risk of falls in older adults, suggests review

Blurred vision contributes to the risk of falling in older adults — but getting new glasses with a big change in vision prescription may increase the risk rather than decreasing it, according to a special article, ’2013 Fry Lecture: Blurred Vision, Spectacle Corr & Falls in Older Adults’ in the June issue of Optometry and Vision Science, official journal of the American Academy of Optometry.The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. Optometrists can help to prevent falls by avoiding over-aggressive vision correction in older patients at risk, according to the review by David B. Continue reading

Misguided DNA-repair proteins caught in the act

Accumulation of DNA damage can cause aggressive forms of cancer and accelerated aging, so the body’s DNA repair mechanisms are normally key to good health. However, in some diseases the DNA repair machinery can become harmful Continue reading
