Myelodysplastic syndromes more common than thought
Medscape Medical News    Share   Share on FacebookTwitterShare on LinkedinE-mail article
Myelodysplastic syndromes (MDS) appear to be nearly fives times more common in older adults than previously thought, according to a new study published online in the Journal of Clinical Oncology. MDS patients face a much higher risk for cardiac-related events, diabetes, hepatic diseases, and infections than the general population in the same age group. However, the study found that three-year survival rates for MDS patients were better, and there were lower transformation rates to acute leukemia than what has previously been reported. More


Scientists find new protein key to bowel disease
Reuters    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Researchers led by scientists from the Pasteur Institute in Lille, France, found that having low levels of a protein called PPAR-gamma, which regulates defenses that kill bacteria in the gut, may make patients less able to fight off gut infections — so boosting PPAR-gamma could help protect against such diseases. The study's results showed that drugs already used for other diseases could prove effective in Crohn's disease. More

Procalcitonin: Uses in the clinical laboratory for the diagnosis of sepsis
Laboratory Medicine via Medscape Medical News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Sepsis is the systemic response to infection by microbial organisms. A differential diagnosis of infection caused by either bacteria or other microbial organisms is essential for effective treatment and prognostic assessment. Current clinical laboratory methods in the diagnosis of bacterial infections are either non-specific or require longer turnaround times. Procalcitonin is a biomarker that exhibits greater specificity than other proinflammatory markers (eg, cytokines) in identifying patients with sepsis and can be used in the diagnosis of bacterial infections.

New insights into the mystery of natural HIV immunity: findings may have implications for designing effective AIDS vaccine

When people become infected by HIV, it's usually only a matter of time, barring drug intervention, until they develop full-blown AIDS. However, a small number of people exposed to the virus progress very slowly to AIDS — and some never develop the disease at all. More

Tainted lettuce linked to illness in 3 states
The New York Times    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A rare strain of E. coli never before associated with foodborne illness in the United States has sickened 29 people in three states, public health officials said. The outbreak has been tied to romaine lettuce served in restaurants, school cafeterias and deli and supermarket salad bars. Freshway Foods, an Ohio company, recalled the lettuce. More

Tumor cells in blood affect breast cancer survival
HealthDay News via Bloomberg BusinessWeek    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The number of circulating tumor cells in the blood of metastatic breast cancer patients directly affects their survival, new research has found. Circulating tumor cells are found in 50 percent to 80 percent of patients whose breast cancer has spread (metastatic breast cancer). It was already known that patients with five or more of these cells in 7.5 milliliters of blood have shorter average survival than those with fewer than five cells. More

New study on how consumers use PHRs has good news for clinical pathology laboratories
DARK Daily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
It will soon be the era of patient health records (PHRs), based on data gathered during a survey conducted by the California HealthCare Foundation. That has implications for clinical laboratories and pathology groups across the United States, since most laboratories now electronically report laboratory test results to physicians and their patients.

Dairy products linked to high prostate cancer risk    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The Food and Drug Administration has reportedly approved a therapeutic vaccine indicated to treat advanced prostate cancer, according to media reports.This vaccine known as Provenge doesn't prevent cancer. It gives patients with advanced prostate cancer four more months to live, said Philip Kantoff of Boston's Dana-Farber Cancer Institute who conducted a trial of 512 men. More

Stem cells from uterus treat Parkinsons in mice
Reuters    Share    Share on FacebookTwitterShare on LinkedinE-mail
Stem cells from the lining of a woman's uterus transformed into brain cells when they were injected into mice whose brains had damage resembling Parkinson's disease, researchers reported. The findings suggest that women with Parkinson's could serve as their own stem cell donors, the team at Yale University School of Medicine in Connecticut said. And because the cells are easy to find, banks of tissue-matched endometrial stem cells could be set up, they said. More

Hepatitis infections behind U.S. rise in liver cancer
HealthDay News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A type of liver cancer, hepatocellular carcinoma, is increasing in the United States, and health officials attribute much of the rise to untreated hepatitis infections. Chronic hepatitis B and hepatitis C are responsible for 78 percent of hepatocellular carcinoma around the world. In the United States, as many as 5.3 million people have chronic viral hepatitis and don't know it, according to Morbidity and Mortality Weekly Report from the U.S. Centers for Disease Control and Prevention.
