Bacteriophage treatment decontaminates infant formula Posted: 23 Oct 2015 11:51 AM PDT A phage showed strong anti-microbial activity against a type of food-borne bacterium that often kills infants after infecting them via infant formula. Phages are viruses that infect only bacteria.

A new algorithm to predict the dynamic language of proteins Posted: 23 Oct 2015 09:18 AM PDT Researchers have developed the first computational method based on evolutionary principles to predict the changes in shape that proteins experience to carry out their functions. This method is a step forward in the study of protein dynamics, of great importance for the design of drugs and the investigation of genetic diseases such as cancer.

Alzheimer risk impairs 'satnav' function of the brain Posted: 23 Oct 2015 05:45 AM PDT Young adults with genetically increased Alzheimer's risk have altered activation patterns in a brain region that is crucial for spatial navigation.

Optical scanner shows potential for real-time 3-D breast cancer screening Posted: 23 Oct 2015 05:41 AM PDT Scientists have developed a hand-held optical scanner with the potential to offer breast cancer imaging in real time. The device uses a near-infrared laser diode source to produce an image of the breast tissues.

Children in foster care three times more likely to have ADHD diagnosis Posted: 23 Oct 2015 05:37 AM PDT Researchers already knew that attention-deficit/hyperactivity disorder was the most common behavioral health diagnosis among children enrolled in Medicaid. A new study found that children in foster care were three times more likely than others to have an ADHD diagnosis.

Most parents form vaccination preferences before becoming pregnant Posted: 23 Oct 2015 05:37 AM PDT Efforts to educate parents about the importance of vaccinations for their children might be more effective if they begin prior to pregnancy, according to findings of a new study.

Lack of adequate food is ongoing health risk to US children Posted: 23 Oct 2015 05:37 AM PDT For the first time, the American Academy of Pediatrics (AAP) is recommending that pediatricians screen all children for food insecurity. In a new policy statement identifying the short and long-term adverse health impacts of food insecurity, the AAP also recommends that pediatricians become familiar with and refer families to needed community resources, and advocate for federal and local policies that support access to adequate, nutritious food.

Iinjuries from nonpowder guns severe among children Posted: 23 Oct 2015 05:37 AM PDT Researchers have shown that nonpowder firearms such as airsoft, BB, and paintball guns should not be viewed as toys, but rather powerful weapons causing increasingly severe and sometimes life-threatening injuries in pediatric patients.

A longer look at treatments for leg length discrepancies Posted: 23 Oct 2015 05:37 AM PDT When balancing treatment options for a child with a significant difference in leg length, doctors typically advise families about the risks and benefits of surgeries to either shorten or elongate one of the limbs. New research suggests they may also want to consider how the child's ultimate height will affect his or her income as an adult.

Health food stores recommend teens try performance supplement not recommended under 18 Posted: 23 Oct 2015 05:37 AM PDT Posing as a 15-year-old athlete wanting to bulk up during strength training, a researcher asked more than 200 health food stores whether he should take a sports performance supplement containing creatine. Despite recommendations against using creatine under age 18 by the American Academy of Pediatrics and the American College of Sports Medicine, more than two-thirds of the stores' sales attendants told him to give it a try.

More than one in five anaphylactic reactions occur in students with no known allergies Posted: 23 Oct 2015 05:37 AM PDT More than 1 in 10 schools in the United States responding to a survey reported at least one severe allergic reaction during the 2013-14 school year, and 22 percent of those events occurred in individuals with no previously known allergies.

New rule that limits tackling during football practices knocks down concussions Posted: 23 Oct 2015 05:37 AM PDT New research shows that limiting the amount of full-contact tackling during high school football practices can have a big impact on reducing the number of concussions among players.

Job opportunities, after-school activities, cleaner city top urban teens' priorities Posted: 23 Oct 2015 05:37 AM PDT When researchers in New Haven, Conn., asked teens to identify solutions to reduce violence in their community, the adolescents had clear recommendations: better employment opportunities, more after-school activities and a cleaner city environment.

Basketball, soccer, lacrosse lead to most ACL injuries among high school female athletes Posted: 23 Oct 2015 05:37 AM PDT A new study finds the overall rate of anterior cruciate ligament injuries among high school athletes is significantly higher among females, who are especially likely to experience ACL tears while playing basketball, soccer and lacrosse.

Research suggests canine companionship helps calm children undergoing cancer treatment Posted: 23 Oct 2015 05:32 AM PDT Although survival rates for children diagnosed with cancer have increased dramatically over the past 40 years, hard evidence of proven psychosocial benefits to improve quality of life among patients and families during treatment has remained elusive.

Hands-only CPR in high school class pumps up likelihood of bystander response to cardiac arrest Posted: 23 Oct 2015 05:32 AM PDT Freshmen at eight Florida high schools who learned how to provide circulatory support to someone in sudden cardiac arrest using chest compressions without mouth-to-mouth ventilations said they would be significantly more comfortable performing the skill in a real-life situation when their training included a hands-on component, according to a new study.

Skin-to-skin contact with baby in neonatal unit decreases maternal stress levels Posted: 23 Oct 2015 05:32 AM PDT Research shows that stable parent-child bonds are fundamental to healthy child development. For parents of babies born prematurely or with special medical needs, this early bonding can be interrupted by the complex medical care required in a neonatal intensive care unit.

ACL injuries increase among school-aged children and adolescents Posted: 23 Oct 2015 05:32 AM PDT A new study confirms what doctors working with young athletes already suspected: the number anterior cruciate ligament (ACL) tears among youths, particularly high school students, has risen during the past 20 years.
