1) Intestinal Nerves May Play Role in Blood Sugar Control
Canadian researchers have found that the intestines play a major role in controlling blood sugar levels, a discovery that could help in efforts to create safer and more effective diabetes medications, the Toronto Star reported.
The University Health Network team's tests on rats revealed that a set of nerves in the intestines is intimately involved in controlling blood glucose levels. This cluster of nerves senses the presence of food and signals the brain to halt the liver's glucose production. But the researchers found that a high-fat diet can switch off this signaling system, the Star reported.
"The cure for diabetes is to lower blood glucose levels... and this will be an innovative and effective approach to do that," said study senior author Tony Lam, the Star reported.
He noted that the gut can access drugs directly, instead of having to rely on blood for drug delivery. This finding about the role of intestines in controlling blood sugar levels could make it easier to create drugs to correct blood sugar problems.
The study was published in the journal Nature.
2) Elevated Lung Cancer Cases in Users of Inhaled Insulin
Patients who used the inhaled insulin product Exubera had an elevated number of lung cancer cases, drug maker Pfizer Inc. disclosed Wednesday. The lung cancer cases were discovered in an analysis of clinical trials and post-approval reports to Pfizer and the U.S. Food and Drug Administration, Bloomberg news reported.
All the patients who developed lung cancer "had a prior history of cigarette smoking" and "there were too few cases to determine whether the development of lung cancer is related to the use of Exubera," Pfizer said in a statement.
Last October, Pfizer stopped selling Exubera, which failed to catch on with patients and doctors due to its cost and cumbersome delivery device, Bloomberg reported.
In addition, the inhaled insulin seemed to decrease lung function, apparently due to the way the insulin was delivered into the lungs, Forbes reported at the time.

"You gain strength, courage, and confidence by every experience in which you really stop to look fear in the face. You are able to say to yourself, "I have lived through this horror. I can take the next thing that comes along." . . . You must do the thing you think you cannot do. " - Eleanor Roosevelt
