Diabetes Gene Raises Odds of Lower Birth Weight
Pediatric researchers have found that a gene previously shown to be involved in the development of type 2 diabetes also predisposes children to having a lower birth weight. The finding sheds light on a possible genetic influence on how prenatal events may set the stage for developing diabetes in later childhood or adulthood.
Researchers from The Children’s Hospital of Philadelphia and the University of Pennsylvania School of Medicine published the study July 10 in the online version of the journal Diabetes.
“It’s a bit unusual to find a gene linked to both prenatal events and to a disease that occurs later in life,” said study leader Struan F.A. Grant, Ph.D., a researcher at the Center for Applied Genomics of The Children’s Hospital of Philadelphia. “This gene variant carries a double whammy, in raising the risk of both lower birth weight and the development of type 2 diabetes in later life.”
Many heart disease patients not referred for rehab
Despite evidence that cardiac rehabilitation helps patients following discharge from the hospital, almost half of heart disease patients eligible for such rehabilitation are not referred for it, according to a new study.
Cardiac rehabilitation involves exercise and counseling on diet and other risk factors. It has been shown to decrease the likelihood of future heart problems.
Dr. Todd M. Brown, from the University of Alabama at Birmingham, analyzed data from the American Heart Association’s Get With The Guidelines program. Included were 72,817 patients who were discharged from 156 hospitals in the US after a heart attack or procedure such as placement of a stent or bypass surgery to clear blocked arteries feeding the heart, between January 2000 and September 2007.
Tiny ovarian tumors lurk for years, study finds
Tiny ovarian tumors lurk in the Fallopian tubes for an average of four years before they grow large enough to be detected, researchers reported on Monday in a study that explains why diagnosis usually comes too late to save a woman’s life.
They said they were trying to find ways to improve testing for the cancer, one of the deadliest because it is so hard to detect before it has spread.
“Reliable early detection would save so many more lives than many new blockbuster anticancer drugs,” Howard Hughes Medical Institute researcher Dr. Patrick Brown of Stanford University in California, who led the study, said in a statement.
