Weight loss surgery to alleviate migraines

A new study from the Miriam Hospital has revealed that bariatric surgery may provide an added benefit to severely obese patients besides weight loss: it can also help alleviate the excruciating pain of migraine headaches.

Researchers say obese patients who had suffered painful and debilitating migraines before bariatric surgery reported improvements in headache frequency, severity and disability just six months after surgery. At that point, most patients had lost an average of 66.4 pounds. “Obesity is thought to contribute to worsening of migraine, particularly for severely obese individuals, yet no study has examined whether weight loss can actually improve migraine headaches in these patients,” said lead author Dale Bond, a researcher with the Miriam Hospital’s Weight Control and Diabetes Research Center.

According to the study, migraine is caused by abnormal brain activity, which is triggered by stress, certain foods, environmental factors, or other factors, although the exact chain of events remains unclear. Migraine pain is usually moderate to severe, often described as pounding, throbbing pain often felt on only one side of the head.

Nicotine raises blood sugar among diabetic smokers

Researchers have found that nicotine is the main culprit responsible for persistently elevated blood sugar levels — and the resulting increased risk of serious health complications — in smokers who have diabetes.  They said the discovery also might have implications for people with diabetes who are using nicotine-replacement therapy for extended periods in an attempt to stop smoking. “This is an important study. It is the first study to establish a strong link between nicotine and diabetes complications. If you’re a smoker and have diabetes, you should be concerned and make every effort to quit smoking,” said Xiao-Chuan Liu.

The gold standard for monitoring long-term blood sugar levels in people with diabetes is the hemoglobin A1c (HbA1c) blood test.  Doctors have known for years that smoking increases the risk of developing complications. Studies also show that smokers with diabetes have higher levels of HbA1c than nonsmokers with diabetes. However, nobody knew the exact substance in cigarette smoke responsible for the elevation in HbA1c. Liu and colleagues suspected it may be nicotine and set out to check nicotine's effects on HbA1c. Using human blood samples, they showed that concentrations of nicotine similar to those found in the blood of smokers did, indeed, raise levels of HbA1c.

Study finds low cancer risk from airport scanners

Researchers have suggested that the cancer risk associated with one type of airport security scanners is low based on the amount of radiation these devices emit, as long as they are operated and function correctly. “The doses are low – extremely low,” said Rebecca Smith-Bindman, a professor at University of California – San Francisco, who made the calculations with Pratik Mehta, an undergraduate at University of California - Berkeley. The amount of radiation absorbed in a single scan, they say, is about the same as what the average person absorbs every three to nine minutes on the ground – just from being alive.
