Here are some of the latest health and medical news developments, compiled by the editors of HealthDay:

First Public Appearance for Hand Transplant Patient

A California woman who received a new hand in a transplant procedure last month is scheduled to appear at a news conference Tuesday.

The 26-year-old mother lost her right hand in a traffic accident several years ago and had been living with a prosthetic. She wanted a new hand to better care for her daughter, the Associated Press reported.

The 14 1/2-hour transplant surgery was conducted at the Ronald Reagan UCLA Medical Center in Los Angeles. During the procedure, a team of nearly 20 surgeons, nurses and support staff connected bones, blood vessels, nerves and tendons between the hand from a deceased donor and the recipient.

The patient was able to move the fingers on her new hand soon after the surgery. She still requires several months of rehabilitation and will have to take anti-rejection drugs for the rest of her life, the AP reported

This is the 13th hand transplant in the United States. The world's first hand transplant was conducted in Ecuador in 1964 and there have been dozens since.


Diet During Pregnancy Affects Child's DNA and Obesity Risk: Study

Eating low levels of carbohydrates during pregnancy can alter a developing child's DNA and increase the risk of childhood obesity, a new study says.

This effect on obesity at ages six and nine years is considerably greater than birth weight and does not depend on how thin or fat the mother is, according to the researchers, BBC News reported.

"All women who become pregnant get advice about diet, but it is not always high up the agenda of health professionals," said study leader Professor Keith Godfrey, from the University of Southampton in the U.K. "The research suggests women should follow the advice as it may have a long term influence on the baby's health after it is born."

The study will appear in the journal Diabetes.

The findings strengthen "the case for all women of reproductive age having greater access to nutritional, educational and lifestyle support to improve the health of the next generation, and to reduce the risk of conditions such as diabetes and heart disease, which often follow obesity," Professor Mark Hanson, of the British Heart Foundation, told BBC News.


Ovarian Cancer Begins in Fallopian Tubes: Study

Ovarian cancer starts in the fallopian tubes, not the ovaries, according to a new study.

Scientists at the Dana-Farber Cancer Institute, Boston, made the finding after conducting lab experiments in which they recreated the process by which ovarian cancer forms, Agence France-Presse reported.

The study, published in the journal Proceedings of the National Academy of Sciences, may lead to new ways to fight ovarian cancer. Each year, about 200,000 women worldwide are diagnosed with ovarian cancer and about 115,000 die of the disease.

A number of previous studies have suggested that ovarian cancer may originate elsewhere, but this study shows how the cancer first takes root in fallopian tissue, AFP reported. The fallopian tubes connect the ovaries to the uterus.


Study of Daily Anti-HIV Pill Halted

A study of a daily pill to prevent HIV infection has been halted because partial results show that the drug offers no benefit to women using it, researchers say.

The findings from the clinical trial involving thousands of African women show that those taking the drug Truvada are just as likely to get HIV as women taking a placebo pill, the Associated Press reported.

The decision to halt the trial was announced Monday by Family Health International, a nonprofit group that launched the study two years ago. While no safety problems were seen with Truvada, women taking the pill were more likely to become pregnant than those taking the placebo.

"That's both a surprising finding and one that we can't readily explain" by what's currently known about the drug's effects on women using hormonal contraceptives, said Dr. Timothy Mastro of Family Health International, the AP reported.

A study released last fall found that Truvada did help prevent HIV infection in gay and bisexual men when used with prevention services such as condoms, counseling.

The leader of that study said it's difficult to understand why the drug didn't protect women against HIV infection. Blood samples may explain whether that failure is related to how faithfully women in the study took the drug, Dr. Robert M. Grant told the AP.

Truvada, made by California-based Gilead Sciences Inc., is a combination of two drugs, tenofovir and emtricitabine. It is already sold for treating HIV infection, the AP reported.
