E-cigarettes: Good news, bad news
Follow me at @JohnRossMD
Americans are confused about electronic cigarettes. A recent poll showed that the public was about evenly split between those who thought that electronic cigarettes, or e-cigarettes, were less harmful than conventional cigarettes, and those who believed that e-cigarettes were as bad as or worse than regular cigarettes.
Unfortunately, there is no long-term safety data about e-cigarettes. What information we do have suggests that e-cigarettes have a complex mix of potential harms and benefits.
E-cigarettes: Less deadly than regular cigarettes
First, the good news: e-cigarettes are almost certainly le...

E-043 Reversible Cerebral Vasoconstriction Syndrome: Non-invasive Imaging Findings and Angiographic Evaluation
We present indirect findings on non-invasive imaging, such as transient cerebral edema, convexal subarachnoid hemorrhage, intraparenchymal hemorrhage and cerebral. Direct signs of single or multivessel arterial vasoconstriction are seen on CTA, MRA and confirmed on DSA. Reversibility of the vasoconstriction is demonstrated after intra-arterial administration of calcium channel blocker. Conditions such as diffuse atherosclerotic arterial narrowing, vasculitis, posterior reversible encephalopathy, cerebral edema secondary to venous congestion and vasospasm secondary to aneurysmal subarachnoid hemorrhage were among the pathol...

Tossing flossing?
The burning question in the news last week was this: should you bother flossing?
The answer for decades has been “of course.” And it’s likely you’ve heard something similar from your dentist. I know I have.
But, while the importance of flossing may have been widely accepted, the evidence supporting it turns out to be surprisingly thin. At least that’s the conclusion of health experts who developed the recently released Dietary Guidelines for Americans, 2015-2020. These guidelines are issued every five years by the U.S. Department of Health and Humans Services and the U.S. Department of Agriculture “…to reflec...

China facing epidemic of heart disease, stroke
(Harvard T.H. Chan School of Public Health) A 20-year rise in cardiovascular disease (CVD) in China appears to have been spurred largely by increases in high blood pressure, according to a new study from Harvard T.H. Chan School of Public Health. Increasing body mass index (BMI), decreasing physical activity, a high prevalence of smoking, and unhealthy diet have also contributed to the growing burden of CVD -- now the leading cause of death in China.

The robot suit providing hope of a walking cure
Clothing that can help people learn how to walk again after a stroke is the brainchild of a Harvard team reinventing the way we use robot technologyConor Walsh ’s laboratory at Harvard University is not your everyday research centre. There are no bench-top centrifuges, no fume cupboards for removing noxious gases, no beakers or crucibles, no racks of test tubes and only a handful laptop computers. Instead, the place is dominated by clothing.On one side of the lab stands a group of mannequins dressed in T-shirts and black running trousers. Behind them, there are racks of sweatshirts and running shoes. On another wall of s...

Why Diet Soda Could Actually Prevent You From Losing Weight
Reaching for a diet soda may actually hinder weight loss efforts, a new study done in mice suggests.
In experiments, researchers found that the artificial sweetener aspartame, which is found in some diet drinks, may contribute to the development of a condition called “metabolic syndrome,” which involves a cluster of symptoms, including high blood pressure, high cholesterol levels and a large waist size. People with metabolic syndrome face an increased risk of heart disease, stroke and diabetes.
The researchers found how aspartame could be linked with metabolic syndrome: Aspartame may stop a key gut enzyme ...

Optimism may reduce risk of dying prematurely among women
(Harvard T.H. Chan School of Public Health) Having an optimistic outlook on life -- a general expectation that good things will happen -- may help people live longer, according to a new study from Harvard T.H. Chan School of Public Health. The study found that women who were optimistic had a significantly reduced risk of dying from several major causes of death -- including cancer, heart disease, stroke, respiratory disease, and infection -- over an eight-year period, compared with women who were less optimistic.
