HPV :: HPV raises throat cancers risk

Researchers at the Johns Hopkins Kimmel Cancer Center have conclusive evidence that human papillomavirus (HPV) causes some throat cancers in both men and women. Reporting in the May 10 issue of the New England Journal of Medicine, the researchers found that oral HPV infection is the strongest risk factor for the disease, regardless of tobacco and alcohol use, and having multiple oral sex partners tops the list of sex practices that boost risk for the HPV-linked cancer.

Smoking :: Cigarette marketing practices in retail stores associated with teen smoking habits

Tobacco display advertising in retail stores appears to be associated with teens experimenting with cigarette smoking, while promotional giveaways and price breaks may be associated with the transition to regular smoking among youth, according to a report in the May issue of Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals.

DNA :: Cataloging the structural variations in human genetics

Using DNA from 62 people who were studied as part of the International HapMap Project, researchers are now looking for structural variations in DNA that may amount to as much as five-10 percent of the human genome. Howard Hughes Medical Institute (HHMI) researchers involved in the project say the amount of work is like doing 62 additional human genome projects.

Diet :: Study confirms health benefits of whole grains

A diet high in whole grain foods is associated with a significantly lower risk of developing cardiovascular disease, including heart disease and stroke, according to an analysis conducted by researchers at Wake Forest University School of Medicine.

Pregnancy :: A few more minutes of maternal attachment may reduce anemia in children

In the past, the newborns’ umbilical cord was not clamped right after birth, thus allowing the blood flow to stop naturally. This practice, known as “late clamping”, was replaced by “early clamping”, that is, cutting the cord immediately after the infant is expelled. However, this new practice lacks studies corroborating its benefits. In fact, recent studies on the importance of when clamping should be done have shown contradictory results.

Bipolar Disorder :: More than 4% of US adults have some form of bipolar disorder

Approximately 4.4 percent of US adults may have some form of bipolar disorder during some point in their lifetime, including about 2.4 percent with a “sub-threshold” condition, according to an article in the May issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

Heart Failure :: Global heartbeat control suggests therapy for beating heart failure

Keeping a healthy heart beating requires the production of a constant supply of energy, a feat depending on the coordination of several genetic programs. Now, researchers report in the May issue of Cell Metabolism, a publication of Cell Press, that two closely related receptors can act together or separately to pull all of the strings.

Sinusitis :: NIH awards VBI, Mayo Clinic $2.4M to study chronic rhinosinusitis

Virginia Bioinformatics Institute and Virginia Tech biological sciences associate professor Chris Lawrence is teaming up with Mayo Clinic on a $2.4 million project funded by the National Institute of Allergy and Infectious Diseases (NIAID). The work could help researchers develop treatments, diagnostic tools, and preventative measures for patients suffering from chronic rhinosinusitis (CRS).

Diet :: Research team sheds light on diet of early human ancestors

Eight years ago, the field of anthropology was rocked by isotopic evidence that suggested one-third of the diet of early human ancestors consisted of grasses and sedges, or the tissue of animals that ate such plants. The news puzzled scientists, who were unable to reconcile the results with what they knew about the teeth of human ancestors who lived more than 2 million years ago.

Pregnancy :: Placental problems in mums who have had a previous caesarean section

New research to be published in BJOG: An International Journal of Obstetrics and Gynaecology shows a link between the development of placenta praevia and placental abruption during the subsequent pregnancies of women who previously had a caesarean section.
