OBJECTIVE—To assess safety, efficacy, and tolerability of pramlintide dose escalation with proactive mealtime insulin reduction, followed by optimization, in patients type 1 diabetes. RESEARCH DESIGN AND METHODS—This 29-week, double-blind, placebo-controlled study randomized 296 to or placebo as an adjunct insulin. During initiation, was escalated from 15 60 μg/meal (15-μg increments) recommended reductions (30–50%) Insulin subsequently adjusted optimize glycemic control. End points included...

The anorectic and weight-suppressive effects of growth differentiation factor-15 (GDF15) are attracting considerable attention for treating obesity. Current experiments in rats investigate whether GDF15 induces an aversive visceral malaise-based state that mediates its acute effect and, through aversion conditioning, exerts longer-term anorexia. Visceral malaise, conditioned affective food responses (taste reactivity), gastric emptying (GE), intake, body weight evaluated after chronic...
