Bonding with newborn baby: Once upon a time in the Intensive Care Unit ... (December 28, 2010) -- The first few days after birth is an important time when babies learn to recognize the sound of their parents' voice and the parents in turn bond with their children.

Circulating tumor cells predicted recurrence, death in patients with early-stage breast cancer (December 27, 2010) -- The presence of one to four circulating tumor cells (CTCs) in the blood of early-stage breast cancer patients almost doubled patient's risk of cancer relapse and death, and five or more CTCs increased recurrence by 400 percent and death by 300 percent, according to Phase III results of the SUCCESS trial. These cells were found in patients after surgery but before chemotherapy treatment. ... > full story

New rule predicts risk of stroke, death from surgery that prevents it (December 27, 2010) -- It's a medical Catch-22: carotid artery surgery can itself cause stroke, but so can asymptomatic carotid disease if left untreated. Researchers have now developed a clinical risk prediction rule using factors such as sex, race and health history to assess the danger the surgery poses, while a modified version will help patients make a more fully informed choice about whether to have the procedure. ... > full story
Poor breast cancer prognosis associated with presence of circulating tumor, cancer stem cells (December 27, 2010) -- Metastatic breast cancer patients whose blood contains circulating tumor cells before or after treatment with high-dose chemotherapy and blood stem cell transplant have shorter survival periods, according to a new study. ... > full story
Recovering from job loss: Most report few long-term psychological effects, study finds (December 27, 2010) -- Losing a job is a profoundly distressing experience, but the unemployed may be more resilient than previously believed -- the vast majority eventually end up as satisfied with life as they were before they lost their jobs, according to a new analysis. ... > full story
Part of brain that suppresses instinct identified (December 26, 2010) -- New research is revealing which regions in the brain fire up when we suppress an automatic behavior such as the urge to look at other people in an elevator. Researchers showed -- for the first time -- an increase in signal from the left inferior frontal cortex when study participants were confronted by a conflict between an image and a word superimposed on the image. ... > full story
Powerful new defibrillator: Minimally invasive surgeries mean smaller scars, quicker recovery (December 26, 2010) -- St. Michael's Hospital has become the first in Ontario to implant a small but powerful new defibrillator into a patient's chest. The defibrillator – about the size of a Zippo lighter – is the smallest available in terms of surface area and can deliver the highest level of energy, 40 joules. ... > full story
