CDC investigates ongoing salmonella outbreak linked to chia products
Centers for Disease Control and Prevention via Infection Control Today
The Centers for Disease Control and Prevention is warning the public about an ongoing outbreak of salmonella infections linked to products containing chia powder. Chia powder is made from small chia seeds that are sprouted and ground into powder. It is often added to health foods like smoothies for its nutritional value.More

Dormant viruses re-emerge in patients with lingering sepsis
Washington University in St. Louis via Bioscience Technology
A provocative study links prolonged episodes of sepsis — a life-threatening infection and leading cause of death in hospitals — to the reactivation of otherwise dormant viruses in the body. In healthy people, such latent viruses are kept in check by the immune system. More

Actionable diagnosis of neuroleptospirosis by next-generation sequencing
The New England Journal of Medicine
More than half the cases of meningoencephalitis remain undiagnosed, despite extensive clinical laboratory testing. Because more than 100 different infectious agents can cause encephalitis, establishing a diagnosis with the use of cultures, serologic tests and pathogen-specific polymerase chain reaction assays can be difficult.More

Fungal protein found to cross blood-brain barrier
University of California, Davis via HealthCanal
In a remarkable series of experiments on a fungus that causes cryptococcal meningitis, a deadly infection of the membranes that cover the spinal cord and brain, investigators at University of California, Davis have isolated a protein that appears to be responsible for the fungus' ability to cross from the bloodstream into the brain.More

Needle biopsies may be underused for breast cancer patients
Reuters
Most women should undergo a needle biopsy for breast cancer diagnosis, but some surgeons opt for a more invasive procedure instead, according to a new study. The difference may be a matter of surgeon experience, researchers say, so many women could benefit if surgeons were trained and encouraged to opt for the needle method more often.More

Stem cells in neurodegeneration: Challenges and future neurotherapeutic prospects
Neural Regeneration Research via Science Codex
Researchers at the University of Florida have demonstrated that inhibition of rho-associated kinase and subsequent cofilin dephosphorylation is mediating neurite outgrowth in PC12 cells. The lack of axonal regeneration in the adult central nervous system is one of the main causes of neurodegenerative disorders. More

Test identifies ovarian cancers in which bevacizumab is no good
Medscape
A new gene expression biomarker test might help guide the treatment of high-grade serous ovarian cancer and avoid the futile use of an expensive type of targeted therapy. The AADx assay helps clinicians determine which patients with high-grade serous ovarian cancer are likely to benefit from antiangiogenic drugs, such as bevacizumab, and which might have worse outcomes with these drugs and do better with standard chemotherapy.More

Preventing infection from the misuse of vials
The Joint Commission
Thousands of patients have been adversely affected by the misuse of single-dose/single-use and multiple-dose vials. The misuse of these vials has caused harm to individual patients through occurrences and outbreaks of bloodborne pathogens and associated infections, including hepatitis B and C virus, meningitis and epidural abscesses.More

Genetic bar code for malaria could help locate disease's origin and contain future outbreaks
Nature Communications via Medical Daily
Bill Gates has revealed to the Internet the deadliest animal in the world. It wasn't sharks or snakes, he points out, or even humans. In fact, it's mosquitoes — for their overwhelming propensity to carry malaria and the parasite that causes it. Now researchers have developed a method to trace the origin of these infections via genetic bar codes.More

Findings provide new strategy for developing safe, effective vaccine against strep throat
University of California, San Diego School of Medicine via News-Medical.net
An international team of scientists, led by researchers at the University of California, San Diego School of Medicine, have identified the genes encoding a molecule that famously defines Group A Streptococcus, a pathogenic bacterial species responsible for more than 700 million infections worldwide each year. The findings, published online in the June 11 issue of Cell Host & Microbe, shed new light on how strep bacteria resists the human immune system and provide a new strategy for developing a safe and broadly effective vaccine against strep throat, necrotizing fasciitis and rheumatic heart disease.More

'High-priority' chemicals that may cause breast cancer named
Medical News Today
An estimated 12.4 percent of women born in the U.S. today will develop breast cancer at some point during their lives. Now, a new study has identified 17 "high-priority" chemicals women should avoid in order to reduce increased risk of breast cancer and demonstrates how their presence can be detected.More

Fasting triggers stem cell regeneration of damaged, old immune system
HealthCanal
In the first evidence of a natural intervention triggering stem cell-based regeneration of an organ or system, a study in the June 5 issue of the Cell Stem Cell shows that cycles of prolonged fasting not only protect against immune system damage — a major side effect of chemotherapy — but also induce immune system regeneration, shifting stem cells from a dormant state to a state of self-renewal.More

Drug-resistant gonorrhoea rates plummet in US
aidsmap
Preliminary results announced at the 2014 STD Prevention Conference in Atlanta have shown that the proportion of cases of drug-resistant gonorrhoea has fallen since 2011, with a sharp decline between 2012 and 2013. The fall is particularly marked in gay and other men who have sex with men, who had had the highest rates of drug-resistant gonorrhoea.More
