NEW YORK (Reuters Health) - While stroke death rates are approximately 50 percent higher than average among residents of the southeastern U.S. -- the so-called 'stroke belt' -- traditional risk factors contribute little to the higher death rates there, a national study indicates.

National homicide rates have remained relatively stable in recent years, with the exception of one group: black teenaged boys. A new report by Northeastern University shows that 54 percent of gun violence victims are black males between the ages of 14 and 17.

Background Reported rates of Chlamydia trachomatis are on the rise contradicting to declining rates of C.trachomatis associated reproductive sequelae. Population based evaluation of the real trend of C. trachomatis infection is important to evaluate prevention efforts. We studied C. trachomatis occurrence during the past 20 years in Finland comparing incidence and prevalence data based on serology and rates based on C. trachomatis laboratory notifications. Methods A random sample of 7 999 women with two consecutive pregnancies within five years was selected from the population of the Finnish Maternity Cohort (FMC) serum bank stratified by calendar year and age. C. trachomatis IgG antibodies were determined by a standard peptide-ELISA. The reported incidence rates of C. trachomatis infections based on case notifications were obtained from the National Registry of Infectious Diseases. Results C. trachomatis seroprevalence rates decreased significantly from 1983 to 2003 both in wo

A new online tool for calculating colorectal cancer risk in men and women age 50 or older was launched today, based on a new risk-assessment model developed by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health.

A research team at the Stowers Institute has discovered how the expression of one of the Hox master control genes is regulated in a specific segment of the developing brain. The findings provide important insight into how and where the brain develops some of its unique and important structures. The findings were posted to the online Early Edition of the Proceedings of the National Academy of Science recently.
