Recalculating costs of combination vaccines

Recalculating costs of combination vaccines

One of the most popular vaccine brands for children may not be the most cost-effective choice. And doctors may be overlooking some cost factors when choosing vaccines, driving the market toward what is actually a more expensive option, according to a new study by University of Illinois researchers. “The choice of vaccines to administer can be driven by numerous factors,” says Sheldon H Continue reading

Brain changes associated with casual marijuana use in young adults: More ‘joints’ equal more damage

Brain changes associated with casual marijuana use in young adults: More ‘joints’ equal more damage

The size and shape of two brain regions involved in emotion and motivation may differ in young adults who smoke marijuana at least once a week, according to a study published April 16 in The Journal of Neuroscience . The findings suggest that recreational marijuana use may lead to previously unidentified brain changes, and highlight the importance of research aimed at understanding the long-term effects of low to moderate marijuana use on the brain. Marijuana is the most commonly used illicit drug in the United States, with an estimated 18.9 million people reporting recent use, according to the most current analysis of the National Survey on Drug Use and Mental Health.

Changes in processing, handling could reduce commercial fishing injuries

Changes in processing, handling could reduce commercial fishing injuries

Handling frozen fish caused nearly half of all injuries aboard commercial freezer-trawlers and about a quarter of the injuries on freezer-longliner vessels operating off the coast of Alaska, new research from Oregon State University shows. Many of those injuries and others aboard the two types of vessels could be prevented with the right interventions, and the research methods used in the study could help identify and reduce injuries and fatalities in other types of commercial fishing, said researcher Devin Lucas.

MRI pinpoints region of brain injury in some concussion patients

MRI pinpoints region of brain injury in some concussion patients

Researchers using information provided by a magnetic resonance imaging (MRI) technique have identified regional white matter damage in the brains of people who experience chronic dizziness and other symptoms after concussion. The findings suggest that information provided by MRI can speed the onset of effective treatments for concussion patients. The results of this research are published online in the journal Radiology Continue reading

Penicillin redux: Rearming proven warriors for the 21st century

Penicillin redux: Rearming proven warriors for the 21st century

Penicillin, one of the scientific marvels of the 20 th century, is currently losing a lot of battles it once won against bacterial infections. But scientists at the University of South Carolina have just reported a new approach to restoring its combat effectiveness, even against so-called “superbugs.” Bacteria have been chipping away at the power of the penicillin family of drugs since their first wide-scale use as antibiotics in the 1940s. For example, the staph infection, brought about by the bacterium Staphylococcus aureus, was once readily treated with penicillin and its molecular cousins. Continue reading

Bad penny: Cancer’s thirst for copper can be targeted

Bad penny: Cancer’s thirst for copper can be targeted

Drugs used to block copper absorption for a rare genetic condition may find an additional use as a treatment for certain types of cancer, researchers at Duke Medicine report. The researchers found that cancers with a mutation in the BRAF gene require copper to promote tumor growth. These tumors include melanoma, the most dangerous form of skin cancer that kills an estimated 10,000 people in the United States a year, according to the National Cancer Institute. Continue reading
