Parents' Influence On Children's Eating Habits Is Small, New Study Finds
The popular belief that healthy eating starts at home and that parents" dietary choices help children establish their nutritional beliefs and behaviors may need rethinking, according to a study by researchers at the Johns Hopkins Bloomberg School of Public Health. An examination of dietary intakes and patterns among U.S. families found that the resemblance between children"s and their parents" eating habits is weak. The results are published in the May 25, 2009, issue of Social Science and Medicine.

SPECT MPI With Cardiolite(R) Used In BARI 2D Study To Evaluate Type 2 Diabetes And Coronary Artery Disease Treatment Strategies
Lantheus Medical Imaging, Inc., a worldwide leader in diagnostic imaging, announced today that the company"s leading imaging agent, Cardiolite® (Kit for the Preparation of Technetium Tc99m Sestamibi for Injection), was used in a recently completed five-year study examining appropriate treatment regimens for patients with type 2 diabetes and coronary artery disease. The results of this study, known as The Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D), will be presented by the University of Pittsburgh Graduate School of Public Health at a special symposium on Sunday, June 7, 2009, from 4:15 p.m. - 5:15 p.m. (CT) at the American Diabetes Association 69th Scientific Sessions in New Orleans.

The Characteristics Of Clarithromycin-Resistant Helicobacter pylori

Clarithromycin is currently one of the antibiotics used for eradication of Helicobacter pylori. However, reports of H. pylori resistance to this antibiotic are increasing worldwide. Clarithromycin resistance has been attributed to the presence of mutations in the 23S rRNA gene, a component of the ribosome that is the protein manufacturing machinery of all living cells. There is little information on the prevalence and characteristics of clarithromycin resistance in H. pylori strains isolated from Malaysian patients. In a research article published in the World Journal of Gastroenterology, the authors determined the prevalence of resistance and characterized the types of mutations present in their resistant strains. In this study conducted by Norazah et al on strains isolated in Malaysia, a low prevalence of clarithromycin-resistant strains was noted. Transitions of adenine to guanine at positions 2142 and 2143 of the 23S rRNA of H. pylori were the main mutations found in clarithromycin-resistant isolates. The A2142G and 2143G mutations of 23S rRNA genes in these strains can be detected easily by restriction fragment length polymorphism (RFLP) analysis of the PCR product of the 23S rRNA genes, using MboII or BsaI restriction enzymes. This eliminates the need to detect these mutations by sequencing. The result of the study demonstrates that clarithromycin resistance is present among local strains. However, even though it is an uncommon occurrence, the possibility of the patient being infected with a resistant strain should be considered if the patient does not respond to treatment with clarithromycin, so that an alternative treatment can be given. The ability to detect clarithromycin resistance by molecular methods such as RFLP showed that this rapid method has the potential to be used as a diagnostic tool.
