Researchers in West Africa have shown that spraying insecticide indoors can dramatically reduce malaria transmission. Efforts to develop a malaria vaccine have so far been disappointing, so programs to control the disease have focused on preventing transmission of the parasite. Insecticide-treated bed nets can prevent mosquito bites that spread the disease, but getting people to
Scientists have taken another big step toward identifying the genetic flaws which may cause autism, a type of neurological development disorder. In the latest development, laboratory mice have been genetically engineered to produce autism-like behaviors. Researchers have known that certain genetic defects are associated with autism. One of the most common is known as a
Apple co-founder Steve Jobs’ death at the age of 56 followed a seven-year battle with a rare form of pancreatic cancer – the fourth leading cause of cancer-related deaths in the United States. The disease is hard to treat because it is difficult to diagnose. The pancreas is embedded deep in the abdomen, and often,
A year ago, the United Nations launched a global campaign called “Every Woman, Every Child,” a public health project aimed at reducing the number of women dying from pregnancy and childbirth-related complications. Our correspondent reports that while some countries are making progress toward that goal, others lag behind. “Every Woman Every Child” was designed to
A new study finds that the use of a hormonal contraceptive popular with women in eastern and southern Africa doubles their risk of becoming infected with HIV. And when it is used by HIV-infected women, it doubles the risk they will infect their male partners. The large study was conducted in sub-Saharan Africa, where HIV
A new kind of electric shock has proved effective in restoring a normal heartbeat in animals, and, if successful in humans, it could represent a gentler alternative to traditional defibrillation. It’s a familiar scene on TV or in the movies – a person’s heart is beating rapidly, out of control. It’s a potentially deadly arrhythmia.
The World Health Organization estimates that 346 million people globally suffer from diabetes. Most of them live in low- and middle-income countries. The WHO projects that if current trends continue, deaths from the disease could double by 2030, and health experts warn it could become a global epidemic, with significant health and economic consequences. Dr.
A major study has found that a hormonal contraceptive widely used in Africa appears to double a woman’s chance of getting HIV, the virus that causes AIDS. The study also suggests that when HIV-positive women used the injectable contraceptive, their male partners were twice as likely to become infected compared to male partners of women
The World Health Organization reports it is very close to eradicating guinea worm, a crippling parasitic disease. WHO says it needs $350 million to finish the job of ridding the world of this ancient, dreaded disease. Campaigners for the global eradication of guinea worm hope to succeed in their efforts to make the disease only
Getting access to adequate health care can be difficult in many parts of rural Indonesia, a necessity that often involves long journeys to overcrowded clinics. And once there, many patients often find they cannot afford the costs of treatment and medication. Take Sukadana for instance, a dusty village outside Gunung Palung National Park in West
