Among more than 46,000 Kaiser Permanente patients in Northern California, heart attack rates fell 24 percent between 1999 and 2008 and the most damaging ST-segment elevation attacks dropped 62 percent. Dr. Alan Go credits cholesterol and blood pressure drugs and quitting smoking.

New autism genes discovered
The Autism Genome Project's second phase, published in Nature, found people with autism carry more copy-number variants than others, including changes in SHANK2, SYNGAP1, DLGAP2 and the X-linked DDX53-PTCHD1 locus. No single mutation explains all symptoms.

Prenatal obesity linked to congenital heart defects
James Mills and colleagues compared 7,392 New York State infants born with congenital heart defects against 56,304 controls and found obese mothers, with a BMI above 30, were 15 percent more likely to have an affected child. Severity of obesity tracked with the risk.
Disease
Richard Dunn dies probably of stroke
Actor Richard Dunn, who often worked with comics Tim Heidecker and Eric Wareheim, died at 73 after several days unconscious. His agent did not give a cause, and some sources said he had suffered a stroke. Americans suffer more than 700,000 strokes each year.
Disease
UN: Cancer will kill 13.2 million people in 2030. What can you do about it?
The International Agency for Research on Cancer projects 13.2 million cancer deaths worldwide in 2030, up from 7.6 million in 2008, and 21.4 million new diagnoses against 12.7 million. Its database shows the burden shifting from wealthy countries to poor ones.
Disease
Brushing teeth prevents heart disease?
Analyzing more than 11,000 adults in the Scottish Health Survey, Richard Watt’s team found people brushing less than twice a day were 70 percent more likely to develop heart disease, though the overall risk stayed low. The study was not a trial and cannot show cause.
Disease
Easy Rider Actor Dennis Hopper Dies from Prostate Cancer
Dennis Hopper died at 74 at his Venice, California home from prostate cancer complications, his production company told ABC News. Diagnosed in October 2009, when doctors found the cancer had already spread to his bones, he spent his final months also fighting his wife in court.
Disease
Gut Bacteria Offer New Hope for People with Celiac Disease
Dr. Mercola cites research in which bifidobacteria raised anti-inflammatory cytokine expression in cell cultures modeling the celiac gut, suggesting probiotics or prebiotics might ease the disease. He notes celiac affects about one in 133 Americans and often takes years to diagnose.
Disease
Olfactory Reference Syndrome Discussed at Convention
Katherine Phillips told an American Psychiatric Association convention about olfactory reference syndrome, in which patients believe part of them smells badly enough that people reject them. In her 20-patient study, three-quarters were convinced they had bad breath.
Disease
Startling Research Findings: A Newly Discovered Cause of High Blood Pressure and Obesity?
Mercola summarises a lecture by Richard Johnson tracing obesity and cardiovascular disease to sugar, especially fructose, and its uric acid connection. Johnson notes 5 percent of the population had blood pressure above 140/90 in 1900, against 31 percent of adults today.
Disease
Severe diabetes means higher cancer risk
German Cancer Research Center scientists compared 125,126 Swedes hospitalized for type 2 diabetes between 1964 and 2007 with the general population, and found pancreatic and liver cancer risks raised about sixfold and fourfold. Prostate cancer and melanoma risks ran lower.
Disease
Dengue Fever Discovered in Key West
The CDC reports dengue cases traced to mosquito bites in Key West, Florida. Unlike earlier U.S. diagnoses, which followed travel to the tropics, this outbreak's source sits on American soil, and the agency stresses diligent vector-borne surveillance in the months ahead.
Disease
Heart attack survivors can have sex as usual
A survey of 1,184 men and 576 women who had heart attacks found only half of men and a third of women were told when it was safe to resume sex before discharge, and both cut back sharply over the following year. Cardiologist Murray Mittleman says the added risk is negligible.
Disease
5 Reasons Why Type One Diabetes is on the Rise
A 2009 Lancet study projected that new type 1 diabetes cases in children could double within a decade. Mercola runs through five proposed explanations: faster growth, less sun, too little germ exposure, early cow's milk formula, and pollutants.
Disease
Postmenopausal breast cancer preventable
Analysing Swedish registry and international incidence data, Hemminki and colleagues report the gap between high- and low-incidence countries lies mainly in postmenopausal breast cancer, which rose over the past century. Rates also differed sharply between white Californians and Asian immigrants.
Disease
High estrone linked to higher prostate cancer risk
In a Urology study comparing 275 prostate cancer cases with 1,652 healthy men aged 65 and older, those in the top three quartiles of estrone were nearly four times as likely to develop prostate cancer as men in the lowest. Testosterone and estradiol showed no such association.
Disease
More genes linked to breast cancer risk
Cambridge researchers scanned the genomes of about 4,000 women with a family history of breast cancer and 24,000 others and found five more DNA loci tied to the disease, bringing the count of common variants linked to breast cancer to 18. The work appears in Nature.
Disease
Take the Next Step after an ADHD Diagnosis
After a diagnosis, behavioral therapy should begin at once, and experts recommend parent training because usual parenting practices may not work. Medication is one option: 70 to 80 percent of children respond to stimulants, and nonstimulants were approved in 2003.
