UXBRIDGE, Canada, Dec 8 (IPS) – Malaria kills a child every 30 seconds, but a new diagnostic breakthrough may cut that devastating death toll, Canadian scientists announced Sunday.

The discovery of “biomarkers” — a telltale biological signature in children’s blood — that identify two of the most lethal forms of malaria was revealed at the annual meetings of the American Society of Tropical Medicine and Hygiene in New Orleans, Louisiana last week.

“A child with a fever may be treated in a clinic with anti-malarial drugs, but that won’t be enough to treat cerebral malaria,” said Conrad Liles, a tropical disease specialist affiliated with Toronto’s McLaughlin-Rotman Centre for Global Health (MRC). Continue reading →

UXBRIDGE, Canada, Oct 23 (IPS)

Gold mining and recycling car batteries are two of the world’s Top 10 most dangerous pollution problems, and the least known, according a new report.

The health of hundreds of millions of people is affected and millions die because of preventable pollution problems like toxic waste, air pollution, ground and surface water contamination, metal smelting and processing, used car battery recycling and artisanal gold mining, the “Top Ten” report found.

“The global health burden from pollution is astonishing, and mainly affects women and children,” said Richard Fuller, director of the New York- based Blacksmith Institute, a independent environmental group that released the list Tuesday in partnership with Green Cross Switzerland.

“The world community needs to wake up to this fact,” Fuller told IPS.

“Few people realize our health is directly tied to the health of the natural world,” — Dr. Aaron Bernstein, Harvard Medical School

Bernstein and colleagues reveal the latest scientific evidence to make a persuasive case that the current extinction crisis, with species vanishing every day, is a serious threat to humanity equal to, if not greater than, climate change.

Their findings are documented in a new book “Sustaining Life“, see here for complete article.

“When we harm nature, we are harming ourselves,” says Bernstein.

CAPE TOWN, South Africa, May 3 (Tierramérica)

“When we harm nature, we are harming ourselves,” says Aaron Bernstein, a doctor at Harvard Medical School and one of the authors of the upcoming book “Sustaining Life: How Human Health Depends on Biodiversity“.

“Few people realise that our health is directly tied to the health of the natural world,” Bernstein told Tierramérica

Bernstein and Harvard colleague Eric Chivian wrote and edited contributions from more than 100 leading scientists in their new book, published by Oxford University Press and available last May.

Written for a general audience, “Sustaining Life” draws on the latest scientific evidence to make a persuasive case that the current extinction crisis, with species vanishing every day, is a serious threat to humanity equal to, if not greater than, climate change.

Pharmaceuticals, biomedical research, the emergence and spread of infectious diseases, and the production of food, both on land and in the oceans, depend on biodiversity — the rich variety of life on our planet. Continue reading →

Vitamin A and Zinc Supplements Cuts Malaria in Africa

Feb 13 (IPS) – Malaria continues to cut a swathe through Africa, which accounts for most cases of the disease and the majority of malaria-related deaths. Globally, more than a million people die from malaria each year. In the case of children, this translates into a death every 30 seconds, according to the World Health Organisation.

A study by Burkina Faso’s Health Sciences Research Institute (Institut de recherche en sciences de la santé, IRSS) may point the way to reducing malaria’s toll on children, however.

IRSS research director Jean-Bosco Ouedraogo and his colleagues report in the current issue of ‘Nutrition Journal‘ that giving vitamin A and zinc supplements to children has been shown to reduce the incidence of malaria among them by a third. The journal is an online publication managed from London.

New ways of fighting malaria are critically needed. In recent years, the disease’s growing resistance to drugs and insecticides (malaria is transmitted by mosquitoes) has made malaria control much more challenging.

Ouedraogo spoke to IPS science correspondent Stephen Leahy.

Organic Cure for Brain-damaging Pesticides Found in US Children

Children eating a normal diet have low levels of organophosphates — the family of pesticides spawned by the creation of nerve gas agents in World War II — according to a recent research says the Seattle Post-Intelligencer.

But once they switched to eating only organic foods these pesticides disappeared within 36 hours from the kids’ bodies.

Malathion and chlorpyrifos were the principal chemicals Emory University’s School of Public Health study found. Death or serious health problems have been documented in thousands of cases with high-level exposures. But impacts at low levels have been more difficult to determine. Animal studies do show chronic dietary exposure to chlorpyrifos results in neurological impairment i.e. brain and nervous system affects.

Experimental Biotech Drugs Flourish in China

Stephen Global Issues and Perspectives, Health, News, Science

nature-biotech.pngJan 7 (IPS) – China’s booming medical biotechnology industry is producing controversial drugs and gene therapy treatment programmes for domestic use, as well as to treat critically ill foreigners seeking potential cures unavailable elsewhere.

China’s Beike Biotechnologies harvests stem cells from the umbilical cord or amniotic membrane and injects them into patient’s spinal region. More than 1,000 patients, including 60 foreigners, have been treated for a variety of conditions including Alzheimer’s disease, autism, brain trauma, cerebral palsy and spinal cord injury, according to a study published Monday in the journal Nature Biotechnology.

“We met foreigners there who were happy with Beike’s treatments,” said Peter Singer of the McLaughlin-Rotman Centre for Global Health at the University of Toronto and co-author of the study. Continue reading →

Smoking Rewires Teenagers’ Brains

Not my usual beat but two important health finding. From New Scientist magazine – 5 Jan/08

“PARENTS may now have another reason to worry about their children smoking. Nicotine may cause the teenage brain to develop abnormally, resulting in changes to the structure of white matter – the neural tissue through which signals are relayed.

Leslie Jacobsen of Yale University School of Medicine has found that teenagers who smoke, or whose mothers smoked during pregnancy, are also more likely to suffer from auditory attention deficits, meaning they find it harder to concentrate on what is being said when other things are happening at the same time.

Nov 26 (IPS) – Chronic, non-infectious diseases like heart disease, stroke, cancer and diabetes kill more than twice as many people than HIV/AIDS, malaria or tuberculosis, experts warn.

In the next 10 years, some 388 million people will die of these largely preventable diseases, which are caused mainly by smoking, poor diet and lack of exercise. Often thought to be diseases of the rich, most of these deaths will be in the developing world, conclude the authors of a study published in the journal Nature this month.

“We have a huge health crisis here that few policymakers and other officials are aware of,” said lead author Dr. Abdallah S. Daar of the McLaughlin-Rotman Centre in Toronto, Canada.

Developing countries, and medical and donor groups have focused almost entirely on infectious diseases, Daar told IPS. “But that’s like putting out one fire in a house burning from both ends,” he said.

“The US has an appalling system that makes it easy to dump e-waste on the developing world.” — Barbara Kyle, Electronics TakeBack Coalition.

Nov 21 (IPS) – U.S. citizens will buy 30 million new digital televisions this year alone, sending their old lead-laden TVs to the dump, or more likely, overseas to China or India.

“It’s an astonishing number that will send millions of pounds of lead to landfills or overseas,” said Barbara Kyle, national coordinator of the Electronics TakeBack Coalition.

Non-digital TVs contain up to eight pounds of lead, which is a potent neurotoxin. While new digital flat screen TVs don’t have lead, they do contain mercury, another neurotoxin.

“It’s no longer illegal in the U.S. to export e-waste (electronic waste) to developing countries,” Kyle said.

Changes in rules and regulations in recent years to the Resource Conservation and Recovery Act, administered by the U.S. Environmental Protection Agency, have created an “appalling system that makes it easy to dump e-waste on the developing world”, she said. Continue reading →
