Accurate determination of cancer origin is necessary to guide optimal treatment but remains a diagnostic challenge. Gene expression profiling technologies have aided the classification of tumors and, therefore, could be applied in conjunction with clinicopathologic correlates to improve accuracy. We report an expanded version of the previously described(More)
OBJECTIVE To assess long-term weight loss efficacy and safety of pramlintide used at different dosing regimens and in conjunction with lifestyle intervention (LSI). RESEARCH DESIGN AND METHODS In a 4-month, double-blind, placebo-controlled, dose-ranging study, 411 obese subjects were randomized to receive pramlintide (six arms: 120, 240, and 360 microg(More)
Background:A dichotomous index combining two gene expression assays, HOXB13 : IL17BR (H : I) and molecular grade index (MGI), was developed to assess risk of recurrence in breast cancer patients. The study objective was to demonstrate the prognostic utility of the combined index in early-stage breast cancer.Methods:In a blinded retrospective analysis of 588(More)
Pramlintide, an adjunct treatment to mealtime insulin for patients with type 2 and type 1 diabetes, aids glycemic control by suppressing postprandial glucagon secretion, slowing gastric emptying, and enhancing satiety. Because gastric emptying affects oral medication absorption, this placebo-controlled, single-blind, crossover study examined the absorption(More)
Evidence from rodent studies indicates that the beta-cell-derived neurohormone amylin exerts multiple effects on eating behavior, including reductions in meal size, intake of highly palatable foods, and stress-induced sucrose consumption. To assess the effect of amylin agonism on human eating behavior we conducted a randomized, blinded, placebo-controlled,(More)
CONTEXT In previous 1-yr trials, treatment with pramlintide (120 microg), an analog of the beta-cell hormone amylin, induced sustained reductions in A1C and body weight in insulin-using subjects with type 2 diabetes. OBJECTIVE To assess the potential of pramlintide as an antiobesity agent, we assessed the weight effect, safety, and tolerability of(More)
Objective:To characterize the interactive effects of amylin with phentermine or sibutramine on food intake, body weight/composition and gene expression in diet-induced obese (DIO) rats.Design:DIO rats were intraperitoneally injected with a single dose of amylin (10 μg kg−1) and/or phentermine (1 mg kg−1) or chronically infused with amylin (100 μg kg−1 d−1)(More)
Breast Cancer Index (BCI) combines two independent biomarkers, HOXB13:IL17BR (H:I) and the 5-gene molecular grade index (MGI), that assess estrogen-mediated signalling and tumor grade, respectively. BCI stratifies early-stage estrogen-receptor positive (ER+), lymph-node negative (LN-) breast cancer patients into three risk groups and provides a continuous(More)
BACKGROUND The integrated central actions of hormones secreted from pancreatic islets, the gut and adipocytes regulate both energy homeostasis and body weight. Dysregulation in these neurohormonal pathways probably contributes to pathogenesis of obesity and type 2 diabetes. OBJECTIVE To examine hormone-based therapies targeting these interrelated pathways(More)
BACKGROUND The aim of neoadjuvant chemotherapy is to increase the likelihood of successful breast conservation surgery (BCS). Accurate identification of BCS candidates is a diagnostic challenge. Breast Cancer Index (BCI) predicts recurrence risk in estrogen receptor+lymph node-breast cancer. Performance of BCI to predict chemosensitivity based on(More)
