Conclusions  Individuals with extreme obesity, compared to the nonobese, obtain less sleep and experience poorer sleep quality. Bariatric
surgery improves sleep duration and quality.

Abstract  Routine drain use after laparoscopic Roux-en-y gastric bypass (LRYGB) is still practiced by many bariatric surgeons. After
a patient in our program experienced intestinal obstruction secondary to a drain, we reevaluated our practice and hypothesized
drains would be of no benefit and potentially harmful after LRYGB. Retrospective record review of all patients undergoing
LRYGB from August 2005 to August 2009 was performed. As we changed our practice in December 2006, we have two comparable groups:
one with a drain placed at surgery and one without. All operations were otherwise performed in an identical fashion by three
fellowship-trained university surgeons. We compared outcomes between the two groups, particularly regarding gastrojejunal
(GJ) leaks. Jejunojejunal …

We present a literature review of the possible mechanisms of early normalization of glycemic homeostasis
after bariatric surgery, including intestinal gluconeogenesis, increased antidiabetogenic signals from L cells located in
the distal small intestine, and impaired secretion of diabetogenic signals in the upper part of the small intestine. Adding
to these potential mechanisms, unknown factors that regulate insulin sensitivity may be involved and altered by bariatric
surgery. This review discusses the various hypotheses about the mechanisms of glycemic control after bariatric surgery involving
intestinal bypass. Further research is essential to better understand these mechanisms and to identify potential new mechanisms
that might help in developing less invasive and safer alternativ…

To the Editor: We read with much interest the recently published article “Effects of obesity and bariatric surgery on airway hyperresponsiveness, asthma control, and inflammation� by Dixon et al. At this juncture, we wish to share a few scientific facts on the published article. (Source: Journal of Allergy and Clinical Immunology)

CONCLUSIONS: Our findings provide clinical evidence that the visceral microenvironment may be intrinsically toxic to arterial health providing a potential mechanism by which visceral adiposity burden is linked to atherosclerotic vascular disease. Our findings also support the evolving concept that both adipose tissue quality and quantity may play significant roles in shaping cardiovascular phenotypes in human obesity.
