Social factors - rather than genetics - are to blame for huge variations in ill health and life expectancy around the world, a report concludes.
The World Health Organization (WHO) has carried out a three-year analysis of the "social determinants" of health.
The report concludes "social injustice is killing people on a grand scale".
For instance, a boy living in the deprived Glasgow suburb of Calton will live on average 28 years less than a boy born in nearby affluent Lenzie.

Similarly, the average life expectancy in London's wealthy Hampstead was 11 years longer than in nearby St Pancras.
The research also shows that a girl in the African country of Lesotho is, on average, likely to live 42 years less than a girl in Japan. BBC News |
 Taking 1000mg of a specific olive leaf extract (EFLA®943) can lower cholesterol and lower blood pressure in patients with mild hypertension (high blood pressure). These findings came from a 'Twins' trial, in which different treatments were given to identical twins.
By doing this, researchers could increase the power of their data by eliminating some of the uncertainties caused by genetic variations between individual people.
Hypertension is one of the most common and important disease risk factors imposed by the modern lifestyle. Many people would therefore benefit from finding ways of reducing blood pressure. Experiments in rats had previously indicated that olive leaf extract could be one way of achieving this goal. Science Daily

 He hated them. “They were too perfect,” Mr. Gafni said. “My nickname in college was Lite-Brite.” As a child, Lite-Brite’s natural teeth had grown in with gray striations, a result of antibiotics he had taken. So when he turned 21, he covered the offending teeth with veneers — wafer-thin pieces of porcelain that are bonded atop filed-down teeth.
Two years ago at 40, Mr. Gafni decided it was time to trade in his flawless teeth for veneers that look natural, but not flawless.
Rebecca Trachtenberg, a nurse practitioner in San Francisco, also asked her dentist to make her veneers subtly less than perfect. “I didn’t want them too white, so he graded them so they get darker as they go back,” said Ms. Trachtenberg, 31. “I also didn’t want them too symmetrical.” The New York Time

 US scientists have discovered a way to transform living pancreatic cells in mice into another type of cell that produces insulin without having to revert to the stem cell stage, creating what is now a third route for cell reprogramming to add to the existing methods of iPS (induced pluripotent stem cells) and hES (human embryonic stem cells).
The study was the work of Harvard Stem Cell Institute co-director Doug Melton and post doctoral fellow Qiao "Joe" Zhou , at Harvard University, Boston, Massachusetts, and colleagues and was published as an advanced online paper in Nature on 27th August. Medical News Today

Ordering traditional Ayurvedic medicines on the Internet may be unsafe.
Approximately one-fifth of Ayurvedic medicines sold online to Americans contain metals, including lead, according to a new study by Boston University researchers. Ayurveda is a traditional medical system used in India and by many South Asians living worldwide.
Since 1978, more than 80 cases of lead poisoning associated with Ayurvedic medicine have been reported, according to the study, published in The Journal of the American Medical Association.
Researchers used five different Internet search engines to locate 25 sites selling Ayurvedic medicines. They identified 673 products and randomly chose 230 to order. These orders were all placed in 2005. After receiving 193 of the 230 products, researchers sent their purchases to the New England Regional EPA for testing. WebMD

 Transplanting faces may seem like science fiction, but doctors say the experimental surgeries could one day become routine.
In papers from two of the world's three teams that have performed partial face transplants, experts said their techniques were surprisingly effective, though complications exist and more work is still needed.
The research was published today in British medical journal The Lancet. Life & Style

 Gene therapy has the potential to restore hearing in mice, offering hope for humans too, US scientists suggest.
An Oregon team discovered gene transfer produced functioning hair cells that are essential for the inner ear to interpret sounds, Nature reports.
In people with normal hearing, cochlear hair cells convert sound into electrical signals, which are ultimately transmitted to the brain.
Once the cells are lost or damaged, they cannot be replaced naturally. BBC News

Study finds reaction, brake response times were better than they had been before procedure
The ability to brake suddenly while driving is fully returned six weeks following bunion surgery, researchers say.
A bunion is the bump just below the big toe that can occur when the big toe begins to angle sideways toward the second toe. Bunions can become swollen and painful, sometimes making it hard to walk. In these cases, surgical treatment to realign the bone, ligaments, and tendons may be required. USA Today

 An ultrasound probe small enough to ride along at the tip of a catheter can provide physicians with clearer real-time images of soft tissue without the risks associated with conventional x-ray catheter guidance.
Duke University biomedical engineers designed and fabricated the novel ultrasound probe which is powerful enough to provide detailed, 3-D images. The new device works like an insect's compound eye, blending images from 108 miniature transducers working together.
Catheter-based procedures involve snaking instruments through blood vessels to perform various tasks, such as clearing arteries or placing stents, usually with the guidance of x-ray images. Science Daily

The virus that causes AIDS is spreading in New York City at three times the national rate — an incidence of 72 new infections for every 100,000 people, compared with 23 per 100,000 nationally — according to a study released on Wednesday by the city’s Department of Health and Mental Hygiene.
The findings, based on a new formula developed by the federal Centers for Disease Control and Prevention, estimated that 4,762 New Yorkers contracted H.I.V. in 2006, the most precise estimate the city had ever offered.
But the city stressed that because the method of estimating infections was new, it could not be said definitively whether the number of new infections in the city had increased or decreased from previous years. The New York Time

 A new study published in the August 15th issue of Biological Psychiatry finds that hippocampal neurogenesis (neuron birth in the hippocampus part of the brain) might be used by the monoaminergic antidepressants (related to the secretion of monoamine neurotransmitters such as dopamine and serotonin) to counteract the effects of stress, whereas similar effects could be achieved by directly targeting the hypothalamo-pituitary-adrenal (HPA) axis and related neuropeptides (amino acid chains).

The drug allopurinol, often prescribed to lower uric acid levels in adults who suffer the painful arthritic condition known as gout, also appears to help lower high blood pressure in teens, according to a new study.
However, the study's lead author emphasizes he is not suggesting that the powerful drug, which can have serious side effects, be used in teens with high blood pressure. He conducted the study to test the hypothesis that lowering uric acid levels can lower blood pressure in teens.
"I really don't want this [study] to be taken to suggest that allopurinol is a good alternative for treatment of blood pressure in children or adults," says Daniel I. Feig, MD, PhD, associate professor of pediatrics at the Baylor College of Medicine in Houston. The drug is too potent, he and other experts say, and the risk of serious side effects make it unattractive to use long-term in teens. WebMD
