Queen Elizabeth II Hospitalized With Stomach Bug

Queen Elizabeth II was admitted to a London hospital on Sunday after she experienced symptoms of gastroenteritis, often referred to as stomach flu.

The 86-year-old monarch's hospitalization was taken as "a precautionary measure," according to a Buckingham Palace spokesman, The New York Timesreported.

The queen was taken to the King Edward VII Hospital by private car and was expected to remain there for about two days. Other than the gastroenteritis symptoms, she is in good health and "in good spirits," the spokesman said.

All the queen's engagements for the next week have been postponed or canceled, including a two-day visit to Italy that was scheduled to begin Wednesday, The Timesreported.

The queen last hospitalized in 2003 for surgery to repair damaged cartilage in her knee.

FDA Report Questions Use of Salmon Hormone to Treat Osteoporosis

A salmon hormone used to treat osteoporosis in post-menopausal women may not reduce the risk of bone fractures enough to outweigh its cancer risks, according to a report by U.S. Food and Drug Administration staff.

It said that three studies of oral, injectable and nasal calcitonin-salmon drugs showed unreliable or disappointing results. Additional research showed that the drugs posed a "plausible" cancer risk, Bloomberg Newsreported.

FDA advisers are scheduled to meet next week to decide if sales of calcitonin-salmon drugs should be halted in the United States. Last year, the European Medicines Agency said that the drugs should not be used to treat osteoporosis.

"This lack of effectiveness when combined with the potential for a cancer risk associated with calcitonin salmon therapy raises concerns about the overall risk and benefit assessment," FDA staff said, Bloombergreported.
