Shanghai families say kids poisoned by lead (AP)

SHANGHAI � Families living in one of Shanghai's many industrial suburbs say their children are suffering from lead poisoning from nearby factories and recycling facilities.

Officials did not respond to calls Thursday requesting comment after families in Kanghua New Village complained that recent checks showed many of their children were suffering from blood lead levels up to nearly nine times the legal limit.

The soaring use of cars and electric scooters, two of the most sought-after accouterments of affluence in China, is driving strong demand for lead acid batteries. But the production and recycling of those batteries and of other electronics components poses a growing environmental threat at a time when government leaders are striving to deliver more sustainable, people-oriented economic growth.

Residents say Kanghua New Village, compact community of modest but modern apartment blocks, was built about 15 years ago to house families moved off farmland to make way for the Kangqiao Industrial Zone.

The source of the lead contamination was not immediately clear, but the village is located just north of the factory zone, amid corn and vegetable fields and older rural housing, and beside chemical, battery and electronics equipment factories.

Milwaukee, Wisconsin-based Johnson Controls Inc. which operates a battery factory nearby, said it was aware of residents' concerns about lead exposure.

"We acknowledge and take these concerns very seriously. We are working with the government to understand and address these issues. However, we have no reason to believe we are the source of the issue," the company said in an emailed statement.

Johnson Controls' battery plant was named a "national model enterprise for occupational health and safety" in 2006, it said. The factory has lead emissions at about one-seventh the Chinese national standard and employees are regularly tested to ensure their blood lead levels remain low enough, the company said.

On Wednesday evening, residents gathered in the village courtyard and playground were eager to show visitors their children's lab reports, showing blood lead levels of 500 micrograms per liter and higher. The legal limit for children is 100 micrograms per liter; none of those tested had levels below 200 micrograms per liter, and most were in the 300-400 micrograms per liter range.

Those results differed from a batch of identical tests done just a week later that showed no abnormalities � leading some residents to suspect that the second round of tests showing normal results were falsified.

"All the earlier reports were very high and the later reports were under the limit. We don't trust the hospital at all," said one resident, who asked only to be identified by her surname, Cai, because of fears of reprisals.

"They should never have built the village right here by the factories. There are battery and recycling factories all around," she said.

Lead poisoning can damage the nervous, muscular and reproductive systems, and children are particularly at risk.

Decades of allowing manufacturers to disregard safety standards, and of heavy reliance on coal, has left much of the country contaminated by toxic metals and chemicals.

Earlier this year, China began cracking down on emissions of lead and other heavy metals following a spate of poisoning cases, mostly in rural areas near factories. Reports of clusters of cases in big cities like Shanghai are uncommon.

Shanghai has moved much of its heavy industry to its sprawling suburbs, but the city of 23 million is so heavily populated that residential areas are still relatively close to factories.

Push underway to cut drugs for dementia patients (AP)

Day after day, Hazel Eng sat on her couch, a blank stare on her face. The powerful antipsychotics she was taking often cloaked her in sedation. And when they didn't, the 89-year-old lashed out at her nursing home's aides with such anger and frequency her daughter wondered if her mother would be better off dead.

Until, in a matter of days, everything seemed to change.

Eng's daughter, Jean Lynch, says her mother was moved to a different section of the Ecumen home in North Branch, Minn., and taken off every drug but her daily aspirin. She now beams as she ambles the hallways, reads the newspaper, tells stories and constantly laughs.

"Now I hope she lives till she's 200 years old," Lynch said. "She's just so happy."

Antipsychotics are meant primarily to help control hallucinations, delusions and other abnormal behavior in people suffering from schizophrenia and bipolar disorder, but they're also given to hundreds of thousands of elderly nursing home patients in the U.S. to pacify aggressive and paranoid behavior related to dementia.

The drugs can limit seniors' ability to effectively communicate, socialize or participate in everyday life. But a series of warnings has prompted a movement of nursing homes trying to reduce the decades-old practice, often resulting in remarkably positive changes.

Still, doctors say the drugs are sometimes the only things that help the small number of dementia patients that display psychotic behavior, making them a danger to themselves and others.

Ecumen's three-year-old program called "Awakenings" isn't just about reducing drugs. Personalized care plans use exercise, aromatherapy, pets and other methods. Patients who were sedated and detached are now playing video games, listening to music and playing balloon volleyball.

"It was quiet before but now it's not," said Eva Lanigan, a nurse who piloted Ecumen's program. "Life is going on here again."

A government audit released in May looked at Medicare payments for atypical antipsychotics, as a newer class of the drugs is known, and found in a six-month period that was analyzed in 2007, about one in seven nursing home patients aged 65 or older had been prescribed them. Some 83 percent of Medicare claims for such drugs were for off-label purposes such as dementia, the audit found.

Since 2005, atypical antipsychotics have been under an FDA warning alerting doctors they could increase the risk of death in patients with dementia due to heart attacks or pneumonia. The most common atypical antipsychotics are sold under the brand names Risperdal, Zyprexa, Seroquel, Geodon, Abilify and Invega.

An older class of the drugs, known as typical antipsychotics, was added to the FDA warning three years later.

The warnings did not apply to other medicines widely used in nursing homes, such as the antidepressants Prozac and Paxil, and the anti-anxiety medicines Xanax and Valium.

Still, off-label use of antipsychotics has continued to be widespread. Some see it as a crutch, used to quiet seniors' outbursts or mask difficult personalities, though many others say it's the only pharmaceutical option to treat a patient with a cadre of behavioral problems.

"Give someone enough medications, you don't have to worry about them wandering around or cursing or fighting," said Dr. Karl Dhana, medical director at MorseLife, which operates a nursing home in West Palm Beach, Fla.

For several years, MorseLife has done quarterly reviews of any patient on an antipsychotic, antidepressant or sedative to see if such medication is necessary. At the start, around a quarter of patients were on such drugs. Dhana said the rate is now around 14 percent.

But the shift hasn't been without challenges. There are no FDA-approved drugs for behavioral problems related to dementia. Nursing home patients today are often sicker and showing more signs of behavior problems than in years past.

Dr. Jason Karlawish, a fellow at the University of Pennsylvania's Institute on Aging, said he uses antipsychotics in only about 5 percent of his dementia patients. But sometimes they're the only thing that helps, such as with a woman he treated who was showing clear signs of psychoses, convinced that her house was on fire.

She attacked caregivers, tore pictures off the wall, wouldn't eat or be bathed. When she was put on an antipsychotic, the symptoms subsided, Karlawish said.

"There is a role for these drugs," he said.

Cobble Hill Health Center, a Brooklyn nursing home, began a program several years back to reduce such drugs, but the home's medical director, Dr. Louis Mudannayake still remembers the doomsday prediction of one nurse.

"She said, `Lou, you're crazy! We're going to have all the patients stripping," he recalled.

Cobble Hill has cut the number of patients on antipsychotics from about 30 percent to less than 15 percent, and the nurse's predictions never came true. The staff has learned to help patients avoid outbursts without pills. The solution is often simple: Asking before entering a room, serving a meal earlier or putting on a favorite Nat King Cole album.

Private "old age homes" began cropping up after Social Security was established in 1935 and by the 1950s, antipsychotic drugs were commonplace and remained so for decades. Some estimated as many as 85 percent of nursing home patients were being given antipsychotics before the Nursing Home Reform Law was passed in 1987.

The use of such drugs was reduced � by around one-third, by some estimates � after the law, but then began to increase again once new antipsychotics were introduced in the 1990s.

The FDA's warning on the drugs led to nursing homes again rethinking their use of antipsychotics. Dr. Izchak Kohen, a geriatric psychiatrist for North Shore-Long Island Jewish Health System, surveyed nursing homes across the country and found 39.1 percent had decreased their use of the drugs since the warning.

Spending by Medicaid � the largest payer of nursing home care in the U.S. � also indicates a shift. For all age groups, in the 2006 fiscal year, antipsychotics drug bills totaled about $7.9 billion for Medicaid. The following year, it dropped to about $4.9 billion. Spending in 2008, the latest year for which data is available, totaled about $3.7 billion.

However, the increasing use of generics may have also helped bring the dollar figure down. The addition of the Medicare prescription drug program, for which some Medicaid patients are also eligible, is also believed to have drawn down the spending figure.

It may be difficult to reduce the use of antipsychotics further, Kohen said, because there aren't alternative drugs. Kohen said he continues to have to prescribe the drugs in certain cases, particularly for elderly dementia patients who are paranoid or aggressive.

"Until we come up with better treatments, I think we're going to have to use them," he said.

Nicole Brandt, a pharmacist who teaches geriatric pharmacotherapy at the University of Maryland and has lectured on antipsychotic use, said low doses of the drugs can sometimes help a dementia patient who is agitated, delusional or hallucinating. But sometimes, she said the drugs are used to treat anxiety, depression or sleep problems, for which they're not helpful.

"There are times when you have to wonder if an antipsychotic is the best treatment," Brandt said. "There may be a safer alternative."

Eng, a retired department store worker with advanced Alzheimer's disease, continues to thrive without the drugs, her daughter says. Teeth grinding that started when she was on the medications, has gone away, and she's again able to feed herself finger foods.

More than anything, though, Lynch says she can tell her mother is happy again. She sees it in her face.

New global killers: heart, lung disease and cancer (AP)

What's killing us? For decades, global health leaders have focused on diseases that can spread � AIDS, tuberculosis, new flu bugs. They pushed for vaccines, better treatments and other ways to control germs that were only a plane ride away from seeding outbreaks anywhere in the world.

Now they are turning to a new set of culprits causing what United Nations Secretary-General Ban Ki-moon calls "a public health emergency in slow motion." This time, germs aren't the target: We are, along with our bad habits like smoking, overeating and too little exercise.

Next week, the U.N. General Assembly will hold its first summit on chronic diseases � cancer, diabetes and heart and lung disease. Those account for nearly two-thirds of deaths worldwide, or about 36 million. In the United States, they kill nearly 9 out of 10 people. They have common risk factors, such as smoking and sedentary lifestyles, and many are preventable.

It's hard to fathom the suffering these maladies are causing in some parts of the world.

For example, until a few years ago Ethiopia had one cancer specialist, Dr. Bogale Solomon, for more than 80 million people.

"Now three more oncologists have joined," he said, and these four doctors struggle to treat patients in a country where cancer drugs and even painkillers are in short supply.

Wondu Bekele took his 2-year-old son, Mathiwos, to that lone cancer center in Addis Ababa when the boy developed leukemia. The desperate father got advice from St. Jude Children's Research Hospital in the United States, procured chemotherapy drugs from India, and against all odds, got his son treated. Yet the little boy died because the hospital had no separate ward to protect him from catching disease from other patients. The father founded a cancer society in his son's name and will represent cancer groups at the U.N. meeting.

"Practically all cancer-related medicines are either nonexistent or beyond the reach of ordinary Ethiopians," he said. "We are struggling to make a difference here."

Advocates may be struggling to make a difference at the U.N., too. Key officials have been unable to agree before the meeting on specific goals � reducing certain diseases or risk factors such as smoking by a specific amount and date. With the global economy in turmoil, finding money to meet any goals could be an even bigger hurdle.

"The timing is difficult with the economy the way it is, but it should not prevent us from setting goals," said Dr. Sidney Smith, who heads the World Heart Federation, an umbrella group of more than 200 organizations focused on heart disease.

"Many of the things we're proposing cost very little" and some, such as smoking cessation, even save money, said Smith, a cardiologist at the University of North Carolina at Chapel Hill. "We're not talking about trying to find a new magic bullet. We're just talking about behavior and cost-effective medicines" like aspirin and generic blood pressure drugs that lower the risk of multiple diseases, he said.

This is only the second time the U.N. has taken up a health issue. The previous one in 2001 led to creation of the Global Fund to Fight AIDS, Tuberculosis and Malaria, with billions from governments and private groups such as the Bill & Melinda Gates Foundation.

Now even rich nations are cash-strapped, and it's unclear whether private groups will step in. Asked whether the U.N. meeting would alter its focus, the Gates Foundation indicated it would not.

"Unfortunately, there is a lack of comparable investment in infectious diseases, which disproportionately affect the world's poorest," said a statement from the foundation. "Our priority will continue to be investing in cost-effective treatments that lead to maximum impact and fill in a gap where other resources are not invested."

However, advocates say there are disparities in chronic diseases, too.

"The common belief that cancer is a problem of rich countries is a misconception," said Dr. Eduardo Cazap, president of the Union For International Cancer Control.

Dr. Ala Alwan, assistant director-general of the World Health Organization, agreed.

"Most countries in Africa are currently overwhelmed with their increasing demand" from cancer patients, and the region also has the highest rates of stroke and high blood pressure in the world, Alwan said.

In Ghana, 23 million people are served by two oncology centers; the country has four cancer doctors and no specialist cancer nurses, said Dr. Allen Lichter, CEO of the American Society of Clinical Oncology, an organization of cancer specialists. The society has trained more than 2,000 doctors in developing countries on cancer care and plans to do more.

Africa also remains the only region in the world where infectious diseases, maternal-infant health problems and poor nutrition still kill more people than noncommunicable diseases do.

Worldwide, stroke and heart-related diseases account for nearly half of all noninfectious disease deaths � 17 million in 2008 alone, WHO says. Next is cancer (7.6 million deaths), followed by respiratory diseases such as emphysema (4.2 million). Diabetes caused 1.3 million deaths in 2008, but that's misleading � most diabetics die of cardiovascular causes.

The U.N. chose to focus on those four diseases and their common risk factors: tobacco use, alcohol abuse, unhealthy diets, physical inactivity and environmental carcinogens.

They have varied impact around the world:

_Europe and North America. These regions are paying the price of too much eating, too little exercise and smoking: heart disease and diabetes dominate. Cancers that are more prevalent with age � breast and prostate � reflect long life spans in these regions where treatment is widely available. In Eastern Europe and the former Soviet Union, lung cancer is the dominant cancer in men. Europe has the highest smoking prevalence in the world: 29 percent.

_Asia. Southeast Asia has the lowest rates of obesity in the world, even lower than Africa. Yet in China, where only 6 percent of the population is obese, nearly 4 in 10 people have high blood pressure. China also has three times the death rate from respiratory diseases as the United States. Many areas also have high rates of infection with HPV, a sexually spread virus that can cause cervical cancer.

In India, the government has launched an aggressive diabetes and high blood pressure screening project. There are 51 million diabetics in India, the second-highest incidence in the world after China. Lung cancer is the most common type of cancer in India among men; in women, it's cervical cancer.

_Central and South America. Cancer prevalence patterns largely resemble North America except that cervical cancer dominates among women in certain areas. Access to care is much poorer in many countries. Dr. Angel Sanchez, an International Cancer Corps volunteer for the American Society of Clinical Oncology, told of conditions at a hospital in Honduras, where there are more than 700 new cancer cases every year for two oncologists to handle.

John Seffrin, CEO of the American Cancer Society, said the U.N. session must lead to specific goals and more money, or a chance to make a difference with these diseases may be lost for decades.

"This is our moment in the sun," he said. "A resolution alone is insufficient."
