China has banned health institutions from withholding care to people with HIV/AIDS after an outcry over a cancer patient with the disease who was denied treatment, state media reported.

The Ministry of Health issued a memo Friday ordering authorities to take steps to guarantee the right to medical treatment for people with the disease, according to the official Xinhua news agency.

Ten years ago there was not a single midwife in the Afghan town of Baharak. Today there are four and the number of women dying in childbirth has fallen dramatically.

Care may still be basic by Western standards, but new midwives like Nasira Karimi mean that in 10 years Afghanistan has seen a staggering improvement in maternal health.

An Emirates Airlines flight was forced to make an emergency landing in Warsaw on Friday after a passenger became fatally ill, airport officials said, echoing a similar event two weeks ago in Prague.

"Medics boarded the plane after the emergency landing early this morning, but were unable to revive the female passenger," Przemyslaw Przybylski, a spokesman for the Polish capital's Chopin Airport, told Agence France Presse.

Older teens and adults with attention deficit disorder are much less likely to commit a crime while on ADHD medication, a provocative study from Sweden found.

It also showed in dramatic fashion how much more prone people with ADHD are to break the law — four to seven times more likely than others.

They came from the remotest parts of Indonesia, taking crowded overnight ferries and riding for hours in cars or buses — all in the hope that a simple, and free, surgical procedure would restore their eyesight.

Many patients were elderly and needed help to reach two hospitals in Sumatra where mass eye camps were held earlier this month by Nepalese surgeon Dr. Sanduk Ruit. During eight days, more than 1,400 cataracts were removed.

Mammograms have done surprisingly little to catch deadly breast cancers before they spread, a big U.S. study finds. At the same time, more than a million women have been treated for cancers that never would have threatened their lives, researchers estimate.

Up to one-third of breast cancers, or 50,000 to 70,000 cases a year, don't need treatment, the study suggests.

Bolsters used to keep sleeping babies on their backs pose a suffocation hazard, health officials warned Wednesday after a recent death raised the 'sleep positioners' toll to at least 13 U.S. infants.

Health officials first warned parents not to use the devices in 2010 and cracked down on manufacturers who claimed they could prevent Sudden Infant Death Syndrome, which claims more than 2,000 infants a year in the United States.

HIV-positive people in Guinea Bissau have been without access to treatment since the Global Fund to fight AIDS suspended funding over an April military coup, the west African nation's AIDS boss said Wednesday.

"Our main funders, the Global Fund, suspended financial aid" following the April 12 coup, said Joao Jose Silva Monteiro, coordinator of the national secretariat to fight AIDS.

China will no longer rely on executed prisoners as a source of transplant organs within two years, a health minister said according to state media Thursday.

High demand for organs in China and a chronic shortage of donations mean that death row inmates have been a key source for years, generating heated controversy.

The hunt for brain injury treatments has suffered a big disappointment in a major study that found zero benefits from a supplement that the U.S. military had hoped would help wounded troops.

The supplement is marketed as a memory booster online and in over-the-counter powders and drinks. It is also widely used by doctors in dozens of countries to treat traumatic brain injuries and strokes, although evidence on whether it works has been mixed.
