Oral microbial profiles differ with varying pneumonia risk
Medscape Medical News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The mix of oral bacteria differs in individuals with different risks for pneumonia, Samit Joshi, DO, MPH, a fellow in infectious diseases at the Yale School of Medicine in New Haven, Connecticut, reported at the Infectious Diseases Society of America 49th Annual Meeting. In a prospective study, Joshi and his team found that the oral microbial profiles are different between community-dwelling adults and adults at higher risk for pneumonia, and that intubated patients who developed pneumonia had profiles that were distinct from those who did not develop it.

Breast cancer stem cell markers CD44, CD24 and ALDH1: Expression distribution within intrinsic molecular subtype
Journal of Clinical Pathology    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The study of CD44/CD24 and ALDH1 expression is the most accurate method to identify cancer stem cells (CSC) from breast cancer populations. However, the overlap between CD44+CD24−/low and ALDH1 CSC phenotypes in breast cancer seems to be very small, as well as their distribution among intrinsic breast cancer subtypes. Due to this discrepancy, it is imperative to improve the understanding of breast CSC marker distribution. More

Clinical pathology laboratories in the United States face tougher accreditation and CLIA environment
DarkDaily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Across the United States, medical laboratory accreditation and CLIA compliance is quietly getting tougher. This is a trend which affects every clinical laboratory and anatomic pathology medical group that must comply with CLIA and meet the accreditation requirements of the Medicare program. One sign that laboratory accreditation and compliance is getting tougher is the increased number of hospital laboratories willing to publicly acknowledge that a recent assessment, survey, or inspection resulted in serious deficiencies.

A new approach to quality control
Clinical Laboratory News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
When the Centers for Medicare and Medicaid Services finalized the Clinical Laboratory Improvement Amendments regulations in 2003, many in the lab community expressed dissatisfaction with what was perceived as ambiguous and unscientific guidance on how to conduct quality control. While the regulations set basic requirements for testing external quality control materials, most laboratories found they needed to go above and beyond these standards to avoid quality problems.

Purging cells in mice is found to combat aging ills
The New York Times    Share    Share on FacebookTwitterShare on LinkedinE-mail article
In a potentially fundamental advance, researchers have opened up a novel approach to combating the effects of aging with the discovery that a special category of cells, known as senescent cells, are bad actors that promote the aging of the tissues. Cleansing the body of the cells, they hope, could postpone many of the diseases of aging. More

AASLD: African-Americans face hepatitis C 'triple whammy'
MedPage Today    Share    Share on FacebookTwitterShare on LinkedinE-mail article
African-Americans face a "triple whammy" when it comes to the hepatitis C virus, a researcher said during the annual meeting of the American Association for the Study of Liver Diseases (AASLD). Two aspects of this triple threat are well known: the high prevalence of the virus in the African-American community and the lower response to therapy of infected individuals. But there's a third threat. More

Researchers aim to untangle Alzheimer's brains
Laboratory Equipment    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Neurofibrillary tangles — odd, twisted clumps of protein found within nerve cells — are a pathological hallmark of Alzheimer's disease. The tangles, which were first identified in the early 1900s by German psychiatrist and neuropathologist Aloysius Alzheimer, are formed when changes in a protein called tau cause it to aggregate in an insoluble mass in the cytoplasm of cells.

Diabetes and the stem cell promise
Los Angeles Times    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Ever since scientists started talking about the medical potential of embryonic stem cells, curing Type 1 diabetes has been one of the dearest dreams. When researchers announced in 1998 that they had derived stem cells from human embryos, their landmark report flagged juvenile-onset diabetes as a disease that might be treated by stem cell transplants.
