CHICAGO (December 28, 2012): When researchers from UCLA Medical Center investigated the link between racial disparities and appendicitis outcomes in children, they found that the type of hospital in which black, Hispanic and other minority patients receive care—community, children's or county—affects their odds of developing a perforated appendix. The study published in the January issue of the Journal of the American College of Surgeons is a first-of-its-kind look at the role hospital type plays in race-based treatment variances among this patient subset.

By showing that tiny particles injected into a liquid crystal medium adhere to existing mathematical theorems, physicists at the University of Colorado Boulder have opened the door for the creation of a host of new materials with properties that do not exist in nature.
(SACRAMENTO, Calif.) — Garen Wintemute, a leading authority on gun violence prevention and an emergency medicine physician at UC Davis, believes broader criteria for background checks and denials on gun purchases can help prevent future firearm violence, including mass shooting catastrophes such as those that occurred at Sandy Hook, Aurora, Virginia Tech and Columbine.

The rate of people who seek preventive cancer screenings has fallen over the last ten years in the United States with wide variations between white-collar and blue-collar workers, according to a University of Miami Miller School of Medicine study published on December 27 in the open-access journal Frontiers in Cancer Epidemiology.
While earlier diagnoses and improved treatments have increased the number of survivors, cancer remains one of the most prominent chronic diseases and, last year alone, claimed the lives of more than 570,000 people in the U.S.
Nine to twelve-year-olds who perform kind acts are not only happier, but also find greater acceptance in their peer groups, according to research published December 26, 2012 in PLoS ONE by Kristin Layous and colleagues from the University of California, Riverside.

In the virtual world of Second Life, female avatars expose substantially more skin than males, independent of their virtual body proportions, according to research published December 26 in PLOS ONE by Matthieu Guitton, who researches perception and human behavior in virtual spaces, and colleagues from Laval University, Canada.
The human tendency to cover up stems from climatic, environmental, physical and cultural constraints, so measuring people's propensity to reveal skin can be difficult in the real world.
Among deployed U.S. service members who died of combat or unintentional injuries between 2001-2011 and underwent autopsies, the prevalence of coronary atherosclerosis was 8.5 percent, with factors associated with a higher prevalence of the disease including older age, lower educational level and prior diagnoses of dyslipidemia, hypertension, and obesity, according to a study in the December 26 issue of JAMA.
Sustained virological response linked with improved survival for patients with chronic HCV infection
Among patients with chronic hepatitis C virus infection and advanced hepatic fibrosis (development of excess fibrous connective tissue), sustained virological response (SVR) to interferon-based treatment was associated with a lower risk of all-cause mortality compared with patients without SVR, according to a study in the December 26 issue of JAMA.
PROVIDENCE, R.I. [Brown University] — When heart attack patients present in the emergency department with some degree of anemia, or anemic patients have a heart attack, physicians have a tendency, but not much guidance, about whether to provide a blood transfusion. The idea is that a transfusion could help more oxygen get to the heart.
CHICAGO – A meta-analysis of 10 studies suggests that receipt of a blood transfusion among patients with myocardial infarction (heart attack) was associated with increased all-cause mortality compared with not receiving a blood transfusion during heart attack, according to a report published Online First by Archives of Internal Medicine, a JAMA Network publication.
Adults who had parents who struggled with addiction, unemployment and divorce are 10 times more likely to have been victims of childhood physical abuse, according to a new study prepared by the University of Toronto's Factor-Inwentash Faculty of Social Work.
NEW YORK (Dec. 20, 2012) -- Diagnosed with severe coronary artery disease, a group of patients too ill for or not responding to other treatment options decided to take part in a clinical trial testing angiogenic gene therapy to help rebuild their damaged blood vessels. More than 10 years later, in a follow-up review of these patients, doctors at Baylor College of Medicine, Weill Cornell Medical College (where the clinical trial and review took place) and Stony Brook University Medical Center report the outcomes are promising and open the door for larger trials to begin.
ANN ARBOR, Mich. — From the moment a stroke occurs, patients must race against the clock to get treatment that can prevent lasting damage. Now, a new study shows the promise – and the challenges – of getting them state-of-the-art treatment safely at their local hospital, saving precious minutes.
The results come from an effort that tested methods to improve delivery of a time-sensitive, clot-busting drug in stroke patients at 24 community hospitals across Michigan. To date, clot-busting treatment has been mostly used at larger hospitals.
