Better Hearing With Bone Conducted Sound
New technology to hear vibrations through the skull bone has been developed at Chalmers University of Technology. Besides investigating the function of a new implantable bone conduction hearing aid, Sabine Reinfeldt has studied the sensitivity for bone conducted sound and also examined the possibilities for a two-way communication system that is utilizing bone conduction in noisy environments.

Majority Of School Nutrition Programs Now Offer Vegetarian School Lunches
School Nutrition Association president Dr. Katie Wilson, SNS announced new data today on the widespread availability of vegetarian school lunch options. Almost two thirds of school nutrition programs now offer a vegetarian school lunch on a consistent basis, up from 22% in 2003, according to the Association"s soon to be released 2009 School Nutrition Operations Report. The availability of vegetarian school lunches in a majority of districts is consistent with the overall trend in the past five years towards more nutritious school lunches emphasizing whole grains, fruits and vegetables, and low-fat dairy. The vegetarian choices also come in spite of federal school lunch reimbursements that have not kept pace with increased food and labor costs. Dr. Wilson presented the research findings at the National Conference on Childhood Obesity in Washington, DC today.

Health Affairs Study Finds No Link Between Cost, Quality Of Care
Quality of care is not linked to the cost of care, according to a study published last week on the Web site of the journal Health Affairs, CQ HealthBeat reports. For the study, researchers from Dartmouth College and Harvard University analyzed the health care bills of chronically ill Medicare beneficiaries in their last two years of life who received end-of-life care from 2,172 unidentified hospitals. The patients had one of three common conditions: heart attack, pneumonia or congestive heart failure. The study -- sponsored by the National Institute on Aging -- looked at common quality indicators at a hospital-by-hospital level instead of regional level (Norman, CQ HealthBeat, 5/22). Researchers compared the data with some of the quality measures reported on the HHS Hospital Compare Web site (Goldstein, "Health Blog," Wall Street Journal, 5/21). The study found that among the one-fifth of hospitals that spent the least, the cost of end-of-life care was $16,059 on average. In comparison, the cost of end-of-life care at the top 20% of highest-spending hospitals was $34,742 on average. The study also found no link -- or even evidence against a link -- between spending and the quality indicators. The researchers noted that the results might be skewed because the quality indicators they used might penalize hospitals that treat sicker patients. In addition, the study used process-of-care measures instead of patient outcomes. According to CQ HealthBeat, the findings of the study could have an effect on the debate over health care reform legislation because lawmakers and President Obama both have said that a reform plan must be able to control costs and expand access to high-quality, affordable health care (CQ HealthBeat, 5/22).

Good Males Are Bad Fathers

Contrary to predictions, males of high genetic quality are not very successful when it comes to fertilizing eggs. A new study on seed beetles by Swedish and Danish scientists Goran Arnqvist and Trine Bilde shows that when a female mates with several males, the males of low genetic quality are the most successful in fertilizing eggs. The study is published in this week"s issue of Science. In almost all animals, females mate with several different males, despite the fact that a single mating is often sufficient to fertilize her eggs. Multiple mating also carries costs to females, such as the risk of catching sexually transmitted diseases. One commonly held belief is that this behaviour may allow females to choose the sperm of the male with highest genetic quality to fertilize her eggs. Professor Gç¶ran Arnqvist from the Department of Ecology and Evolution, Uppsala University and associate professor Trine Bilde from the Department of Biological Sciences, University of Aarhus, have tested this possibility directly for the first time and shown that it is not true. Their study on seed beetles shows that, contrary to predictions, males of low genetic quality are more successful in fertilizing eggs. Males who gained the highest share of paternity were actually males with low genetic quality. These males also fathered offspring that did less well. "The results support the suggestion that genes that are good for males may often be bad for their mates. Therefore, in beetles at least, multiple mating does not award females with genetic benefits," says Gç¶ran Arnqvist. Goran Arnqvist Uppsala University
