New antibiotic cures disease by disarming pathogens, not killing them

A new type of antibiotic can effectively treat an antibiotic-resistant infection by disarming instead of killing the bacteria that cause it. Researchers report their findings in the October 2 issue of mBio®, the online open-access journal of the American Society for Microbiology.

Trojan horse drug therapy provides new approach to treating breast cancer

When Linda Tuttle was diagnosed with breast cancer, she never imagined her experience would inspire her colleagues to design new treatments to tackle the disease.

An administrative assistant in the Department of Chemistry at Wake Forest University, Tuttle was more accustomed to talking to faculty and staff about meetings and course loads – not doctors' appointments and treatment plans.

Low levels of vitamin D are associated with mortality in older adults

Chevy Chase, MD—Low levels of vitamin D and high levels of parathyroid hormone are associated with increased mortality in African American and Caucasian older adults, according to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology and Metabolism (JCEM). The study also indicates that the potential impact of remediating low vitamin D levels is greater in African Americans than Caucasians because vitamin D insufficiency is more common in African Americans.

A simple blood test could be used to detect breast cancer

A SIMPLE blood test could one day be a more accurate way to test for the early signs of breast cancer than using mammograms to spot a lump say researchers today (Tuesday), as Breast Cancer Awareness Month gets underway.

They also hope the blood test could improve treatment by detecting whether breast cancer patients are likely to relapse and what drugs their particular type of tumour will respond to.

Sexually abused women much less likely to be screened for cervical cancer

[Barriers to cervical screening in women who have experienced sexual abuse: an exploratory study 2012; 38: 214-20 (Research)

The effect of childhood sexual abuse on women's lives and their attitudes to cervical screening 2012; 38:1-2 (Editorial)]

Women who have been sexually abused as children or young adults are much less likely to get screened for cervical cancer than other women, indicates exploratory research published in the Journal of Family Planning and Reproductive Health Care.

Study examines safety of quadrivalent HPV vaccine given to females

CHICAGO – A study of girls and young women in California suggests that the quadrivalent human papillomavirus vaccine (HPV4) appeared to be associated with syncope (fainting) on the day of vaccination and skin infections in the two weeks after vaccination, according to a report published Online First by Archives of Pediatrics & Adolescent Medicine, a JAMA Network publication.

Study affirms safety of HPV4 vaccine for adolescents and young women in routine clinical care

OAKLAND, Calif. — A study of almost 200,000 young females who received the quadrivalent human papilloma virus (HPV4) vaccine found that immunization was associated only with same-day syncope (fainting) and skin infections in the two weeks after vaccination. These findings support the general safety of routine vaccination with HPV4 in a clinical care setting to prevent cervical and other genital and reproductive cancers.

GI societies issue new colonoscopy surveillance guidelines

Bethesda, MD (Oct. 1, 2012) — Patients at average risk of colorectal cancer who have a clean colonoscopy do not need to repeat the test for 10 years. This and many other practical recommendations for cancer prevention were issued in "Guidelines for Colonoscopy Surveillance After Screening and Polypectomy,"1 a consensus update issued by the U.S. Multisociety Task Force on Colorectal Cancer.

New technologies advance livestock genomics for agricultural and biomedical uses

MINNEAPOLIS / ST. PAUL (10/01/2012) —New genome editing technologies developed at the University of Minnesota for use on livestock will allow scientists to learn more about human diseases.

Researchers harness the immune system to improve stem cell transplant outcomes

Richmond, Va. – (October 1, 2012) – A novel therapy in the early stages of development at Virginia Commonwealth University Massey Cancer Center shows promise in providing lasting protection against the progression of multiple myeloma following a stem cell transplant by making the cancer cells easier targets for the immune system.

Misconduct, not error, accounts for most scientific paper retractions

October 1, 2012 — (Bronx, NY) — In sharp contrast to previous studies suggesting that errors account for the majority of retracted scientific papers, a new analysis—the most comprehensive of its kind—has found that misconduct is responsible for two-thirds of all retractions. In the paper, misconduct included fraud or suspected fraud, duplicate publication and plagiarism. The paper's findings show as a percentage of all scientific articles published, retractions for fraud or suspected fraud have increased 10-fold since 1975.

Breakthrough in understanding lung cancer vulnerabilities points the way to new targeted therapy

More effective treatments for one of the deadliest forms of cancer are one step closer thanks to groundbreaking research from an international collaborative study.

Scientists from the Universities of Sheffield and Cologne have identified the dependencies of multiple Small Cell Lung Cancer (SCLC) types – paving the way for clinical trials of new targeted treatments which could revolutionise the current approach.

Around 40,000 people are diagnosed annually with lung cancer in the UK, and SCLC accounts for nearly one in five of all these cases.

A form of small pox virus shows potential for treating triple-negative breast cancer

CHICAGO—Researchers from Memorial Sloan-Kettering Cancer Center (MSKCC) in New York City have shown that a new vaccinia virus, acting as both an oncolytic and anti-angiogenic agent, can enter and kill triple-negative breast cancer (TNBC) cells. Study findings presented today at the 2012 Annual Clinical Congress of the American College of Surgeons could leadto a more targeted therapy against this deadly form of breast cancer.

Zinc deficiency mechanism linked to aging, multiple diseases

CORVALLIS, Ore. – A new study has outlined for the first time a biological mechanism by which zinc deficiency can develop with age, leading to a decline of the immune system and increased inflammation associated with many health problems, including cancer, heart disease, autoimmune disease and diabetes.

Popular antidepressant Paxil might prevent heart failure

ANN ARBOR—A medication usually used to help treat depression and anxiety disorders has the potential to help prevent heart failure, according to researchers at the University of Michigan.
