What Is Puberty? What Is Early Puberty? What Is Late Puberty?
Puberty is the period in children"s lives when they experience physical changes by which their bodies eventually become adult bodies that are capable of reproducing. Puberty is triggered by hormone signals from the brain to the ovaries and testes (gonads). The ovaries (in girls) and testes (in boys) respond to hormone signals from the brain by producing a range of hormones that stimulate the growth, function and change in various parts of the body, including the reproductive organs, breasts, skin, muscles, bones, hair and the brain.

Lower Levels Of Key Protein Influence Tumor Growth In Mice, Stanford Study Shows
Tumors need a healthy supply of blood to grow and spread. Researchers at the Stanford University School of Medicine have identified a molecule that regulates blood vessel growth that is often found at less-than-normal levels in human tumors. Blocking the expression of the molecule, called PHD2, allows human cancer cells to grow more quickly when implanted into mice and increases the number of blood vessels feeding the tumor.

New Medicare Data Compare Hospitals Based On Readmissions

New data regarding hospital readmission rates have emerged "amid a national debate over how to reduce" these numbers, "which cost the federal government billions of dollars a year in Medicare reimbursements," the New York Times reports. The data, posted on Medicare"s Hospital Compare Web site, examines the number of patients "readmitted to hospitals within a month of being discharged after treatment for heart attack, heart failure or pneumonia between July 2005 and June 2008." "Hospitals in New York State are significantly worse than those elsewhere in the nation at limiting patients from having to return shortly after being treated for a major illness, according to federal data released on Thursday," the Times reports. Local hospital spokespeople said the density of poverty in the urban area contributed to the disparity, but officials also noted that some hospital that seem many poor patients actually performed better than major academic centers (Hartocollis, 7/9). The Salt Lake Tribune reports, "[r]esearch shows that hospital readmissions are reducing the quality of health care while at the same time increasing costs, according to [the Medicare program]. On average, about one in five Medicare beneficiaries who is discharged from a hospital today will return within a month." In Utah, hospitals performed at about the national average, or better in some cases (Rosetta, 7/9). One Dallas hospital, Baylor Heart and Vascular Hospital, did the best in the quality measures, the Dallas Morning News reports. That hospital, and others like it, are now being offered as examples. "If that kind of savings [from low readmissions] were applied around the country, $1.8 billion would be saved each year," the hospital"s Chief Medical Officer said (Roberson, 7/10).
