Instead of eating less saturated fat and worrying about so-called bad cholesterol, a group of doctors suggests an alternative approach for preventing heart disease.
More important, they say, is to focus on decreasing insulin resistance and inflammation in the body by targeting diet, exercise and reducing stress.
“If we target all those three things together (plus) a reduction of smoking then we’ll combat 80 percent of all heart disease,” said Dr Aseem Malhotra of Lister Hospital in Stevenage, UK, who coauthored an editorial in the British Journal of Sports Medicine.
Saturated fats are …

Even as doctors are increasingly relying on home blood pressure monitoring to manage patients with hypertension, many of the devices are too inaccurate to be useful, according to a small study.
About 70% of the time, home monitors weren’t accurate within 5 mmHg, which is considered clinically important, researchers say. And 30% of the time, the devices were 10 mmHg off the mark.
Hypertension, or high blood pressure, “is the number one cause of death and disability in the world,” said lead study author Jennifer Ringrose of the University of Alberta in …

Inhaled nanoparticles like those pumped out in vehicle exhausts can work their way through the lungs and into the bloodstream where they can raise the risk of heart attack and stroke, scientists say.
In experiments using harmless ultra-fine particles of gold, the scientists were able for the first time to track how such nanoparticles are breathed in, pass through the lungs and then gain access to the blood.
Most worryingly, the researchers said at a briefing in London, the nanoparticles tend to build up in damaged blood vessels of people who already …

A landmark Australian law on restrictive tobacco packaging has been upheld at the World Trade Organization after a five-year legal battle, Bloomberg news reported on Thursday, citing two people familiar with the situation.
The news is a blow to the tobacco industry as such a ruling from the WTO has been widely anticipated as giving a green light for other countries to roll out similar laws.
It could have wider implications if applied to packaging for alcohol and junk food.
The Australian law goes much further than advertising bans and graphic health warnings …

A cheap and widely available drug could save the lives of one in three of the 100,000 new mothers who bleed to death after childbirth every year, mostly in poorer countries, according to the first study of its use in postpartum haemorrhage.
In a trial of 20,000 women, researchers found that the drug, called tranexamic acid or TXA, cut the number of deaths due to post-partum bleeding by 31 percent if given within three hours. The treatment costs about $2.50 in most countries, they said.
As TXA works by stopping blood clots …

Drinking 32 ounces of energy drink is associated with potentially harmful changes in blood pressure and heart function that are beyond those seen with caffeine alone, according to a new study.
There are more than 500 energy drink products on the market, and their increased popularity is matched by a significant rise in energy drink-associated emergency department visits and deaths.
Manufacturers and fans of these products claim they are as safe as caffeine, but there is little evidence to support that claim.
Caffeine in doses up to 400 mg (about five cups of …

Two scientific studies published this week suggest the risk of children developing autism after their mothers used antidepressants while pregnant may be lower than previously believed.
One of the studies in the findings in the Journal of the American Medical Association included 1.5 million infants in Sweden from 1996 to 2012, making it one of the largest populations ever analyzed to understand the impact of antidepressant use during pregnancy.
The study found that mothers’ use of antidepressants early in pregnancy did not increase the risk of their children developing autism.
The report said …

The World Health Organization on Wednesday hailed “unprecedented progress” in the fight against 18 neglected tropical diseases — including dengue fever and sleeping sickness — which kill 170,000 people and disable millions each year.
The U.N.’s health agency, pharmaceutical companies and civil society groups led by the Bill and Melinda Gates Foundation have been waging a protracted effort to eradicate the group of highly treatable diseases, which had previously received scant attention and resources.
“It’s really a story of wonderful progress,” the billionaire Microsoft founder Bill Gates said in Geneva. “A lot …

An ultra-sensitive, wearable sweat sensor may improve diagnosis and treatment of cystic fibrosis, diabetes and other conditions, researchers say.
Unlike previous sweat sensors, the new model requires only a trace of moisture to do its job and doesn’t require patients to sit still for 30 minutes while it collects sweat.
“This is a huge step forward,” said co-author Carlos Milla, associate professor of pediatrics at Stanford University.
The wearable device, designed in collaboration with researchers at the University of California, Berkeley, contains flexible sensors and microprocessors that stick to the skin and stimulate …

Having reduced sensitivity to insulin may lead to more rapid decline in memory and other mental skills in old age even among people who don’t have diabetes, a recent study suggests.
So-called insulin resistance, the body’s failure to respond normally to the hormone insulin, is a hallmark of diabetes. Diabetes itself – a disease in which the body can’t properly use insulin to convert blood sugar into energy – has been linked to cognitive decline and dementia, but the exact nature of the connection isn’t as clear.
In the current study, researchers …
