Cognitive function is disrupted by both hypo- and hyperglycemia in school-aged children with type 1 diabetes: a field study.

Objective: We developed a field procedure using personal digital assistant (PDA) technology to test the hypothesis that naturally occurring episodes of hypo- and hyperglycemia are associated with deterioration in cognitive function in children with type 1 diabetes.

Research Design And Methods: A total of 61 children aged 6-11 years with type 1 diabetes received a PDA programmed with two brief cognitive tests (mental math and choice reaction time), which they completed just before home glucose readings. The computer recorded time to complete each test and number of correct responses.

Psychosocial evaluation of bariatric surgery candidates: a survey of present practices.

Objective: Successful outcome for bariatric surgery is largely dependent on patients' ability to adhere to postoperative behavior changes. A thorough psychological evaluation is often required before patients' approval for surgery. In addition to a standard psychiatric interview, assessment of behavioral components specific to this surgery seems indicated.
