MRSA infection risk after facelift surgery

Methicillin-resistant S aureus?positive surgical site infection is an increasingly problematic issue in all surgical fields. In the future, MRSA-positive infections will be more prevalent and will require well-developed screening, prevention, and treatment strategies. – About one-half percent of patients undergoing facelift surgery at one outpatient surgical center between 2001 and 2007 developed methicillin-resistant Staphylococcus aureus (MRSA) infections, according to a report in the March/April issue of Archives of Facial Plastic Surgery, one of the JAMA/Archives journals.

Race differences affect response to drugs and infections

Gene expression differences between those of European and African ancestry affect response to drugs and infections. – Differences in gene expression levels between people of European versus African ancestry can affect how each group responds to certain drugs or fights off specific infections, report researchers from the University of Chicago Medical Center and the Expression Research Laboratory at Affymetrix Inc. of Santa Clara, CA.

Copper inhibits transmission of hiv through breast milk and blood

Researchers have developed an inexpensive copper-based filter that may prevent HIV from being passed through breast milk and blood. – Researchers from the U.S. and abroad have developed an inexpensive copper-based filter that may prevent HIV from being passed through breast milk and blood. They report their findings in the February 2008 issue of the journal Antimicrobial Agents and Chemotherapy.

Gastric acid protects against foodborne diseases

Low levels of gastric acid in the stomach can increase one?s likelihood of getting a foodborne infection. – A new study suggests that low levels of gastric acid in the stomach can increase one’s likelihood of getting a foodborne infection. The researchers from Australia report their findings in the February 2008 issue of the journal Infection and Immunity.

Many maternal deaths worldwide are preventable

A study published in PLoS Medicine this week suggests that of women who die during pregnancy and childbirth in sub-Saharan Africa, more may die from treatable infectious diseases than from conditions directly linked to pregnancy. – Women who die during pregnancy and childbirth in sub-Saharan Africa, more may die from treatable infectious diseases than from conditions directly linked to pregnancy, revealed by researchers.

Cholesterol lowering drug may fight staph infection

Cholesterol lowering drug could offer a new direction for therapies against staph infection – a bacterium that’s becoming increasingly resistant to antibiotics. – An international team of researchers supported by the National Institutes of Health (NIH) has blocked staph infections in mice using a drug previously tested in clinical trials as a cholesterol-lowering agent. The novel approach, described in the February 14 online edition of Science, could offer a new direction for therapies against a bacterium that’s becoming increasingly resistant to antibiotics.

Beetroot juice can beat high blood pressure

Research shows a daily dose of beetroot juice can beat high blood pressure. Drinking beetroot juice, or consuming other nitrate-rich vegetables, might be a simple way to maintain a healthy cardiovascular system. – Drinking just 500ml of beetroot juice a day can significantly reduce blood pressure, revealed by researchers at Barts and The London School of Medicine in a new study. Beetroot juice could have major implications for the treatment of cardiovascular disease.

Chronic drinking can lead to pneumonia after surgery

Consistent alcohol consumption can impair immunity functions following surgery. Study authors recommend that patients considering surgery control their drinking habits, and also be very honest with their doctors about their drinking habits, prior to surgery. – People who drink often have immune-function problems following surgery. For example, patients who consume alcohol long-term have a two- to five-fold greater chance of post-operation infection complications. A new rodent study has found that chronic consumption ? in this case, the equivalent of prolonged moderate drinking ? can result in a more severe form of pneumonia following surgery.

Babies excrete vaccine-mercury quicker

Infants? bodies expel the thimerosal mercury much faster than once thought ? thereby leaving little chance for a progressive building up of the toxic metal. – February’s issue of Pediatrics offers another reason to rethink blaming the spike in autism diagnoses on thimerosal, a mercury-containing preservative routinely used in several childhood vaccines until the late ?90s.

Manuka honey with natural antibacterial methylglyoxal

Manuka Health New Zealand Ltd announced the launch of the first manuka honey products certified to contain levels of the antibacterial ingredient. – The natural compound methylglyoxal is responsible for Manuka Health New Zealand’s manuka honey’s unique health-giving properties, revealed in a publication by a German university scientist, reported the company.
