Fainting after air travel may indicate pulmonary embolism

Fainting after recent air travel could be a sign of pulmonary embolism (PE), a potentially fatal blockage in the lungs. Syncope or fainting is an uncommon symptom of pulmonary embolism; however, new research presented at CHEST 2012, the annual meeting of the American College of Chest Physicians (ACCP), found that fainting associated with recent air travel may be a key indicator for PE diagnosis. Fainting as a precursor to PE diagnosis was also associated with a saddle embolism, a larger and more life-threatening form of PE, as well as more abnormal ECG readings.

In vitro fertilization linked to increase risk for birth defects

In vitro fertilization (IVF) may significantly increase the risk of birth defects, particularly those of the eye, heart, reproductive organs and urinary systems, according to new research presented Saturday, Oct. 20, at the American Academy of Pediatrics (AAP) National Conference and Exhibition in New Orleans.

According to the study, despite increasing use of IVF in the United States, associations between birth defects and IVF are poorly understood. Management of birth defects comprises a large part of pediatric surgical care and demands significant health care resources.

Microspectroscopy technique for identifying metastatic phenotype of breast cancer cells

Researchers at the Bellvitge Biomedical Research Institute (IDIBELL) and The Institute of Photonic Sciences (ICFO) have collaborated on the development of a diagnostic tool that identifies the metastatic ability of breast cancer cells. The analysis is based on the characterization of the lipid component of the cells, which is indicative of malignancy. This has allowed the researchers to develop a classifier to discriminate cells capable of inducing metastasis. The results of the study have been published in the online version of the scientific journal PLoS ONE.

Loosing weight does not offer cardiovascular benefit in type 2 diabetes patients

An intensive diet and exercise program resulting in weight loss does not reduce cardiovascular events such as heart attack and stroke in people with longstanding type 2 diabetes, according to a study supported by the National Institutes of Health.

The Look AHEAD (Action for Health in Diabetes) study tested whether a lifestyle intervention resulting in weight loss would reduce rates of heart disease, stroke, and cardiovascular-related deaths in overweight and obese people with type 2 diabetes, a group at increased risk for these events.

Daily multivitamins reduce risk of cancer in men

A daily multivitamin can help a man reduce his risk of cancer, according to new research from Brigham and Women's Hospital (BWH). The first-of-its kind study will be presented October 17 at the 11th Annual AACR International Conference on Frontiers in Cancer Prevention Research and published online the same day in the Journal of the American Medical Association.

"The Physicians' Health Study II is the first clinical trial to test the affects of multivitamins on a major disease such as cancer," said lead author J. Michael Gaziano, MD, chief of the Division of Aging at BWH and an investigator at VA Boston. "Despite the fact that more than one-third of Americans take multivitamins, their long-term effects were unknown until now."
