Parental misconceptions about concussions could hinder treatment, recovery Posted: 10 Oct 2014 12:50 PM PDT With football season in full swing, there's no shortage of talk about young players -- from high school down to the pee wee levels -- suffering from concussions. Yet many parents may lack knowledge about this mild traumatic brain injury, according to two studies.

Moms who choose to breastfeed older babies motivated by health, nutrition benefits Posted: 10 Oct 2014 12:50 PM PDT Mothers who decide to breastfeed their children beyond 1 year of age consider their child's physical and social development to be most important, while the advice of health care professionals, family and friends are least important, according to a study.

Counting pitches can save young players' arms but not always used consistently Posted: 10 Oct 2014 12:50 PM PDT Guidelines on how many pitches young athletes should throw have been developed to stem the tide of injuries, but many coaches are not following the recommendations consistently, according to a study.

Incorrect use of car seats widespread on first trip home from hospital, research shows Posted: 10 Oct 2014 12:50 PM PDT Nearly all parents unknowingly put their newborn infants at risk as soon as they drive away from the hospital due to mistakes made with car safety seats, according to research.

Hidden population: Thousands of youths take on caregiver role at home Posted: 10 Oct 2014 12:50 PM PDT While the typical preteen or adolescent can be found playing sports or video games after school, more than 1.3 million spend their free time caring for a family member who suffers from a physical or mental illness, or substance misuse. These 'caregiving youth' are a hidden population who are at risk of school failure and poor health.

Impact of patient-to-physician messaging reviewed in study Posted: 10 Oct 2014 12:49 PM PDT While it may take time before it's known what impact email exchanges might have on patients and their care, a new study offers some early insights into the effects on doctors, suggesting that reimbursement models and physician workflow may need to adjust to accommodate message management.

Computerized surveillance system quickly detects disease outbreaks among preschoolers Posted: 10 Oct 2014 12:49 PM PDT A web-based system that allows preschools and child care centers to report illnesses to local public health departments could improve the detection of disease outbreaks and allow resources to be mobilized more quickly.

Study shows incorrect use of splints causes skin injuries, poor healing in children Posted: 10 Oct 2014 12:49 PM PDT More than 90 percent of potential pediatric fractures are splinted improperly in emergency rooms and urgent care centers, which can lead to swelling and skin injuries, according to a study.

Neural stem cell overgrowth, autism-like behavior linked, mice study suggests Posted: 10 Oct 2014 12:49 PM PDT A new study shows how, in pregnant mice, inflammation, a first line defense of the immune system, can trigger an excessive division of neural stem cells that can cause "overgrowth" in the offspring's brain, and, ultimately, autistic behavior.

Recent kidney policy changes have not created racial disparities in care Posted: 09 Oct 2014 06:03 PM PDT After the implementation of a new payment system for kidney failure care and changes to dosing guidelines for anemia drugs, there were no meaningful differences by race regarding changes in management practices or laboratory measures among dialysis patients, a study has concluded.

Does Facebook make you lonely? Posted: 09 Oct 2014 01:34 PM PDT Existing research on the impact of Facebook on loneliness has been examined in a recent study. The conclusion: Facebook didn't make people lonely, but lonely people were more likely to use the popular social media site.

Adolescent chronic pain costs $19. 5 billion a year in United States Posted: 09 Oct 2014 12:39 PM PDT Chronic pain affects about 5 percent of children and adolescents. They seek more medical care, use more medication, miss more school, and report worse quality of life than their peers without pain, but little has been known about the costs of chronic pain in childhood and adolescence. In a new study, researchers sought to better understand the economic costs to society due to adolescent chronic pain.

Genomic diversity of individual lung tumors revealed Posted: 09 Oct 2014 12:38 PM PDT The challenge of what scientists call genomic heterogeneity, the presence of many different variations that drive tumor formation, growth and progression, has now been addressed by scientists. The researchers conducted whole exome sequencing on 48 tumor regions from 11 surgically removed localized lung adenocarcinomas, cancers that form in the epithelial tissue that lines the lung. Surgery for these non-small cell lung cancers is potentially curative.

Cold exposure prompts body to convert white fat to calorie-burning beige fat Posted: 09 Oct 2014 11:14 AM PDT Exposure to cold temperatures can convert white fat tissue from the thighs and belly to beige fat that burns calories for heat, but this biological response is hampered in obese people, according to a new study.

Endocrine-disrupting chemicals alter thyroid hormone activity during pregnancy, affect thyroid hormone activity Posted: 09 Oct 2014 11:14 AM PDT A new study in human placenta provides the strongest evidence to date that Endocrine Disrupting Chemicals (EDCs) can interfere with thyroid hormone action in pregnant women. The implication is that flame retardant chemicals called polychlorinated biphenyls (PCBs) can infiltrate the placenta during pregnancy and affect thyroid hormone activity at the cellular level, according to a new study.

Giant leap for diabetes: From human embryonic stem cells to billions of human insulin producing cells Posted: 09 Oct 2014 09:56 AM PDT Stem cell researchers have announced that they have made a giant leap forward in the quest to find a truly effective treatment for type 1 diabetes, a condition that affects an estimated three million Americans at a cost of about $15 billion annually.

Environmental taxes encourage lower consumption Posted: 09 Oct 2014 09:49 AM PDT Tobacco taxation and environmental taxes on electricity and gasoline is the most effective way for politicians to get consumers to understand the problems of smoking and pollution. Expenditure on media campaigns from government and industry, and lobbying by the industry, most effectively influences consumers' consumption of tobacco and gasoline in the United States, one expert notes.
