Subchondral bone changes contribute to cartilage damage and loss

A recent study determined that bone area predicted the development of medial (inner side) and lateral (outer side) knee cartilage damage and loss of medial cartilage volume. Subchondral bone mineral density (BMD) was associated with medial defect development but not cartilage loss. Researchers believe subchondral bone changes and loss of cartilage contribute to the development of osteoarthritis (OA). Read details of the study online or in the July issue of Arthritis & Rheumatism, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology.

Gap in preventive care exists among Latinos, study shows

"Prevention" is the new buzzword for health professionals and the new emphasis for containing future health care costs. Yet Latinos, who currently represent about 15 percent of the U.S. population, have the lowest level of preventive care of all racial and ethnic groups in the nation.

Depth charge: Using atomic force microscopy to study subsurface structures

Over the past couple of decades, atomic force microscopy (AFM) has emerged as a powerful tool for imaging surfaces at astonishing resolutions—fractions of a nanometer in some cases. But suppose you're more concerned with what lies below the surface? Researchers at the National Institute of Standards and Technology (NIST) have shown that under the right circumstances, surface science instruments such as the AFM can deliver valuable data about sub-surface conditions.

Swiss media likely to twist positive health messages

Analysis of a series of public health campaigns in the Swiss media has shown that, although the campaign was entirely focussed on positive messages, the resulting stories often featured 'negative' threats and warnings. The study, published in the open access journal BMC Research Notes, also found that the campaign was much more successful in the German media, compared to French or Italian.

Informal childcare curbs chances of infants being breastfed

Babies who are looked after by relatives, friends, and neighbours while their mothers are at work, are less likely to be breastfed, suggests research published online in the Archives of Disease in Childhood.

This applies to both full time and part time care, and all strata of society, the research indicates.

The findings are based on 18,050 infants, who were part of the UK Millennium Cohort Study, which tracks the long term health and wellbeing of children born between 2000 and 2002.

ACGME task force proposes graduated duty hour and supervision standards

Analyzing food and beverages with magnetic levitation

Scientists are reporting development of a new use for magnetic levitation, or "maglev," the futuristic technology best known for enabling high-speed passenger trains to float above the tracks. In ACS' bi-weekly Journal of Agricultural and Food Chemistry, they describe putting maglev to use in an inexpensive sensor for analyzing food, water, and other beverages.

High levels of fructose, trans fats lead to significant liver disease, says study

Scientists at Cincinnati Children's Hospital Medical Center have discovered that a diet with high levels of fructose, sucrose, and of trans fats not only increases obesity, but also leads to significant fatty liver disease with scar tissue.

Moreover, the researchers conducted the study in a new mouse model of obesity and liver disease that so closely models human disease they will now be able to test therapies to determine their effectiveness, according to Rohit Kohli, M.D., a gastroenterologist at Cincinnati Children's Hospital Medical Center and the study's main author.
