NEW ORLEANS – All-terrain vehicle (ATV) manufacturer warning labels aimed at children under age 16 are largely ineffective, and formal dealer-sponsored training is infrequently offered and deemed unnecessary by most young ATV users, according to new research presented at the Oct. 22 at the American Academy of Pediatrics (AAP) National Conference and Exhibition in New Orleans. The study of ATV crashes involving children also found less than 35 percent of children were wearing a helmet when injured in an ATV crash, and nearly 60 percent were riding again within six months.

NEW ORLEANS – High schools with athletic trainers have lower overall injury rates, according to a new study, "A Comparative Analysis of Injury Rates and Patterns Among Girls' Soccer and Basketball Players," presented Oct. 22 at the American Academy of Pediatrics (AAP) National Conference and Exhibition in New Orleans. In addition, athletes at schools with athletic trainers are more likely to be diagnosed with a concussion.

NEW ORLEANS – Despite a new federal law that prohibits the sale of adult-sized all-terrain vehicles (ATVs) for use by children under age 16, most ATV sellers are willing to discuss doing so, according to new research presented Oct. 22 at the American Academy of Pediatrics (AAP) National Conference and Exhibition in New Orleans.

STANFORD, Calif. — Online health records could be surprisingly useful for at-risk teenagers who cycle through the juvenile justice system. A new study from the Stanford University School of Medicine and the Santa Clara Valley Medical Center found that these young people have high rates of Internet use and an unexpectedly favorable attitude toward accessing their health records online.

New research suggests that antibiotics are not effective in treating cough due to the common cold in children. The study, presented at CHEST 2012, the annual meeting of the American College of Chest Physicians, found that when children with acute cough were treated with either antitussive medication or antibiotics, antibiotics alone showed a lower percentage of cough resolution.

High blood pressure, blood sugar, blood lipids, and body mass index—characteristics that are often lumped together as the metabolic syndrome—are jointly linked with an increased risk of dying from prostate cancer. That is the conclusion of a new study published early online in CANCER, a peer-reviewed journal of the American Cancer Society. The study's results suggest that public health recommendations regarding diet and lifestyle to prevent heart disease and diabetes may also decrease a man's likelihood of dying from prostate cancer.

Roflumilast was associated with significant improvements in lung function in patients with moderate and severe chronic obstructive pulmonary disease (COPD) after 6 months of treatment compared with placebo. Roflumilast is approved to reduce the risk of exacerbations in patients with severe COPD associated with chronic bronchitis and a history of exacerbations.

Children with asthma who have their tonsils and adenoids (T&A) removed may experience fewer asthma symptoms.

Researchers from Children's Hospital and Research Center in Oakland, California, followed 105 children with asthma (7-21 years) referred for sleep study for suspected sleep apnea. Twenty-four patients with sleep apnea required T&A, of which 11 patients followed through with surgery. Results indicated that asthma scores trended toward improvement with T&A. However, there was no significant increase in the lung function following T&A.

Heavy concentrations of secondhand smoke, such as those found in smoke-filled bars and cars, can lead to airway restriction for bystanders within minutes of exposure. The study, presented at CHEST 2012, the annual meeting of the American College of Chest Physicians, showed that after 20 minutes of exposure to highly concentrated secondhand smoke, participants experienced near immediate physiologic changes, including airway resistance and impedance.

College education and alcohol consumption may be linked to risk for chronic obstructive pulmonary disease (COPD). Researchers from Kaiser Permanente Medical Group in Oakland, California, followed 126,019 people who supplied baseline data from 1978 – 1985 through 2008 with analyses of hospitalizations attributed to COPD (emphysema, chronic bronchitis, or chronic airway obstruction).

Patients who have undergone resection for non-small cell lung cancer (NSCLC) may improve their overall survival and reduce the risk of recurrence by taking statins. Researchers from Northwestern University Feinberg School of Medicine, Chicago, and Penn State Hershey Cancer Institute followed 803 patients who underwent resection for NSCLC, of which 315 were using statins. Results showed that statin use was associated with a significantly lower local recurrence rate and significantly higher overall survival compared with non-statin users.

Difficulty breathing, chest pain, and cough may sound like symptoms of a heart attack; however, new research shows that these are the key symptoms for pulmonary embolism (PE), a potentially fatal blockage in the lung. A research team from Saint Vincent's Medical Center in Bridgeport, Connecticut, retrospectively reviewed the clinical features, risk factors, and ECG findings in 334 patients with confirmed PE.

LA JOLLA, CA – October 21, 2012 – Biochemists at The Scripps Research Institute (TSRI) have discovered a genetic sequence that can alter its host gene's activity in response to cellular energy levels. The scientists have found this particular energy-sensing switch in bacterial genes, which could make it a target for a powerful new class of antibiotics. If similar energy-sensing switches are also identified for human genes, they may be useful for treating metabolism-related disorders such as type 2 diabetes and heart disease.

Reflective surfaces polarize light, a phenomenon that fishermen or photographers overcome by using polarizing sunglasses or polarizing filters to cut our reflective glare. However, PhD student Tom Jordan from the Bristol Centre for Complexity Sciences and his supervisors Professor Julian Partridge and Dr Nicholas Roberts in Bristol's School of Biological Sciences found that these silvery fish have overcome this basic law of reflection – an adaptation that may help them evade predators.

When animals and plants are exposed to influences such as bacterial attack, odour and cold, calcium ions flow into the cells. The calcium provides the cells with a signal about what is going on outside, but as high concentrations of calcium are toxic to the cells, it must be quickly pumped out again. Researchers from the Danish National Research Foundation's PUMPkin Centre at both the University of Copenhagen and Aarhus University have now shown that calcium pumps in the cell's outer membrane adjust the pump speed very accurately to the calcium concentration.
