Could the quality of your attachment to your parents affect your own child's risk for obesity
Date: Feb-04-2014Could the quality of your attachment to your parents affect your own child's risk for obesity? A new University of Illinois study says it can."If your mother regularly punished or dismissed your anger, anxiety, or sadness instead of being sensitive to your distress and giving you strategies for handling those feelings, you may be insecurely attached and parenting your children in the same way. A child who doesn't learn to regulate his emotions may in turn develop eating patterns that put him at risk for obesity," said Kelly Bost, a U of I professor of human development and family studies.
Microspheres could be key in preventing bone infections after joint replacement
Date: Feb-04-2014Currently more than 1 million knee replacements and hip replacements are performed each year in the United States, and with the aging population, the number of total joint replacements is expected to grow.While total joint surgeries have a low risk of infection - between 1 and 3 percent - in those rare instances when bone infection sets in, it can be a devastating setback for patients.
Caregiving and psychological stress
Date: Feb-04-2014When it comes to life's stressors, most people would put caregiving at the top of the list. But according to Peter Vitaliano, a professor of psychiatry and psychology at the University of Washington (UW), there never have been data actually showing caregiving causes psychological distress. So he, and other researchers at the UW conducted a study of about 1,228 female twins, some were caregivers, and some were not. The results were somewhat surprising.The study, "Does caregiving cause psychological distress?

Protein serves as a natural boost for immune system fight against tumors
Date: Feb-04-2014Substances called adjuvants that enhance the body's immune response are critical to getting the most out of vaccines. These boosters stimulate the regular production of antibodies -- caused by foreign substances in the body -- toxins, bacteria, foreign blood cells, and the cells of transplanted organs.But, biologists think that vaccine adjuvants could be much better: The currently available licensed adjuvants are poor inducers of T helper cells and even worse at inciting killer T cells that clear viruses, as well as eradicate cancer cells.
Sex-specific patterns of recovery from newborn brain injury revealed by study
Date: Feb-04-2014Physicians have long known that oxygen deprivation to the brain around the time of birth causes worse damage in boys than girls. Now a study by researchers from the Johns Hopkins Children's Center conducted in mice reveals one possible reason behind this gender disparity and points to gender-specific mechanisms of brain repair following such injury.
Simple, at-home test will detect most colorectal cancers
Date: Feb-03-2014Tests that require patients to collect a single stool sample at home and then send it to a lab for analysis will detect about 79 percent of colorectal cancers, according to a new evidence review published in the Annals of Internal Medicine. The review of 19 studies examining eight different fecal immunochemical tests, know as "FITs", also finds that the tests will correctly identify about 94 percent of patients who do not have cancers of the rectum or colon.
HPV vaccine 'does not lead to risky sexual behavior in teens'
Date: Feb-03-2014Some parents might worry that the human papillomavirus vaccine could lead to more sex or more unsafe sex in teenagers and young people. However, a new study conducted by the Cincinnati Children's Hospital Medical Center in Ohio and published in the Pediatrics journal finds that these concerns are unwarranted.Human papillomavirus (HPV) is one of the most common sexually transmitted infections (STIs). In the US, HPV affects 7.5 million teenage girls and young women between the ages of 14 and 24.
Immune system kills spontaneous blood cancer cells every day
Date: Feb-03-2014A new study from Australia suggests B cells, a type of white blood cell, undergo spontaneous changes that could lead to cancer if the immune system does not carry out regular checks and kill them before they form tumors.In the journal Nature Medicine, Dr. Axel Kallies, of the Walter and Eliza Hall Institute in Parkville, Victoria, and colleagues report that the immune system removes errant B cells before they become cancerous."Each and every one of us has spontaneous mutations in our immune B cells that occur as a result of their normal function," Dr. Kallies says.
Probe detects staph infection faster, more cheaply
Date: Feb-03-2014Currently, to test if patients are infected with Staphylococcus bacteria, commonly known as staph, doctors have to take a biopsy and send it for analysis. Now, researchers from the University of Iowa have developed an ingenious noninvasive chemical probe that can detect the presence of a common species of staph in less than an hour.The probe specifically targets Staphylococcus aureus, a species of staph that is common both inside hospitals and out in the general community.
