Researchers at the University of California, San Diego School of Medicine say metastatic colorectal cancer patients of African-American descent are less likely to be seen by cancer specialists or receive cancer treatments. This difference in treatment explains a large part of the 15 percent higher mortality experienced by African-American patients than non-Hispanic white patients.

 

The brain processes visual input to the level of understanding its meaning even if we never consciously perceive that input, according to new research published in Psychological Science, a journal of the Association for Psychological Science.

 

Probiotics are not new, but their status as a nutritional buzzword is. Most folks have now heard and seen the term countless times in commercials and advertisements, as yogurt, dietary supplement, natural food product, and even cosmetic companies promote their probiotic-containing products.

 

Contrary to common belief, parents do not generally treat their stepchildren less favourably than their own. Until now, many researchers believed in the so-called “Cinderella effect.” It states that it is biologically inevitable that parents care less for stepchildren because they do not spread their genes. Researchers at the Max Planck Institute for Demographic Research (MPIDR) in Rostock, Germany, have discovered an important exception. If there is a reasonable chance of increasing wealth in the parents’ environment then no difference is made between one’s own children and stepchildren. Thus, parental care depends on more than just the biological relationship.

 

A new study published in the American Journal of Preventive Medicine gives new insight into the geographic variation in drug poisoning mortality, with both urban centers and rural areas showing a large increase in death rates. While previous studies have looked at drug poisoning related deaths in broad strokes, this is the first study to examine them on the county level across the entire U.S.

 

The first study to look extensively at sexual function in women who underwent bariatric surgery found that significant improvements in overall sexual function, most reproductive hormones and in psychological status were maintained over two years following surgery. Women reporting the poorest quality of sexual function prior to surgery saw the most dramatic improvements one year after surgery, on par with women who reported the highest quality of sexual function prior to surgery.  The new report by researchers with the Perelman School of Medicine at the University of Pennsylvania appears in the November 4 edition of JAMA Surgery.
