Less can be more when removing lymph nodes during breast cancer surgery

Posted: 01 Oct 2013 02:56 PM PDT

A conservative approach to removing lymph nodes is associated with less harm for breast cancer patients and often yields the same results as more radical procedures, researchers at UT Southwestern Medical Center have found.

Telestroke Service Increases Rates of 'Clot-Buster' Treatment for Stroke, Reports Neurosurgery

Posted: 01 Oct 2013 01:46 PM PDT

A telestroke service increases the rate of effective tissue plasminogen activator (tPA) therapy for patients with acute ischemic stroke treated at community hospitals, according to a report in the October issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

Lactation May Be Linked to Aggressive Cancer in Mexican Women

Scientific data suggest that a woman reduces her risk of breast cancer by breastfeeding, having multiple children and giving birth at a younger age. A study led by the University of California, San Diego School of Medicine and recently published online by Cancer Epidemiology, Biomarkers & Prevention, indicates that women of Mexican descent may not fit that profile. In fact, results suggest that women of Mexican descent with more children and those who breastfeed are more likely to be diagnosed with an aggressive form of breast cancer.

High Blood Sugar Levels Linked to Increased Wound Complications after Surgery, Reports Plastic and Reconstructive Surgery

A new study released today shows that among patients undergoing surgery for chronic wounds related to diabetes, the risk of wound-related complications is affected by how well the patient's blood sugar levels are controlled before surgery. These findings appear in the October issue of Plastic and Reconstructive Surgery®, the official medical journal of the American Society of Plastic Surgeons (ASPS).

New Map of Insulin Pathway Could Lead to Better Diabetes Drugs

Posted: 01 Oct 2013 08:47 AM PDT

A team led by scientists at The Scripps Research Institute (TSRI) has created the first comprehensive roadmap of the protein interactions that enable cells in the pancreas to produce, store and secrete the hormone insulin. The finding makes possible a deeper scientific understanding of the insulin secretion process—and how it fails in insulin disorders such as type 2 diabetes.
