(University of Pennsylvania School of Medicine) Even members of the lay public who have received CPR training are confused about how to perform the lifesaving skill and say they don't have confidence in their ability to do it properly, according to a study from the Perelman School of Medicine at the University of Pennsylvania which will be presented today at the American Heart Association's annual Scientific Sessions.

(University of Pennsylvania School of Nursing) Doctors have been dispensing advice to heart failure patients and for the first time researchers have found that it works.

While self-care is believed to improve heart failure outcomes, a highlight of the recent American Heart Association scientific statement on promoting heart failure self-care was the need to establish the mechanisms by which self-care may influence neurohormonal, inflammatory, and hemodynamic function.

(University of Pennsylvania School of Medicine) A physician panel in the primary care specialty of internal medicine has identified common clinical activities where changes in practice could lead to higher quality care and better use of finite clinical resources.

The study identifying the top five list of internal medicine activities appears online in the Archives of Internal Medicine.

(University of Pennsylvania School of Medicine) Patients who've been hurt in car or bike crashes, been shot or stabbed, or suffered other injuries are more likely to live if they arrive at the hospital on the weekend than during the week, according to new University of Pennsylvania School of Medicine research published in the March 21 issue of Archives of Surgery.

(University of Pennsylvania School of Medicine) For rodent pups, bonding with mom isn't hard-wired in the womb. It develops over the first few weeks of life, which is achieved by their maturing sense of smell, possibly allowing these mammals a survival advantage by learning to identify mother, siblings, and home.

Blending electrophysiological, biochemical and behavioral experiments, researchers demonstrated that neurons in the noses of mice mature after birth.

(University of Pennsylvania School of Medicine) CPR quality is worse during in-hospital cardiac arrests occurring overnight than those that happen during the day, according to a new University of Pennsylvania School of Medicine study that will be presented at the American Heart Association's annual Scientific Sessions on Nov. 14.

(University of Pennsylvania School of Medicine) Early trials using targeted monoclonal antibodies in combination with existing therapies show promise in treating pancreatic cancer and metastatic breast cancer, according to research that will be presented by investigators from the University of Pennsylvania's Abramson Cancer Center at the 2010 meeting of the American Society of Clinical Oncology.

(University of Pennsylvania School of Medicine) Louis J. Soslowsky, Ph.D. Fairhill professor of Orthopaedic Surgery and professor of Bioengineering, director of the McKay Orthopaedic Research Laboratory and Penn Center for Musculoskeletal Disorders at the University of Pennsylvania School of Medicine, was named the 2010 winner of the Ann Doner Vaughan Kappa Delta Award by the American Academy of Orthopaedic Surgery.

(University of Pennsylvania School of Medicine) Researchers have developed a new model of skin cancer based on the knowledge that a common cancer-related molecule called Src kinase is activated in human skin-cancer samples.

(University of Pennsylvania School of Medicine) Errors in cell division can cause mutations that lead to cancer, and a new study could shed light on the role of chromosome abnormalities in uncontrolled cell replication.

They uncovered the molecular players and mechanism underlying a little-studied stage of cellular division called Anaphase B.
