Medical Research: What is the background for this study?
Dr. Wallace: Since its first consideration as an independent entity in 1996,
1 intraductal papillary mucinous neoplasms (IPMN) of the pancreas have been diagnosed with increasing frequency
. Detection and resection of IPMN offer a unique opportunity to cure and prevent
adenocarcinoma of the pancreas, an otherwise highly lethal disease. The main clinical concern related to intraductal papillary mucinous neoplasms is its wide-ranging potential for malignancy from low-risk indolent lesions to those with high incidence of malignant degeneration. It is well-established that this malignant progression varies based on the morphological subtypes. The current methods of predicting malignant potential are limited to clinical, morphological, and cyst fluid cytology and biomarker data.
Medical Research: What are the main findings?
Dr. Wallace: Of 1126 patients, 84 were diagnosed with invasive carcinoma/high-grade dysplasia and were compared to the rest of the cohort. Multivariate logistic analysis showed no statistically significant association between cancer/high-grade dysplasia and gender, age or alcohol consumption. Smoking history and body mass index was significantly related with cancer/ high-grade dysplasia. Jaundice and steatorrhea were also associated with cancer/ high-grade dysplasia; however, weight loss was not. Univariate analysis showed no association between malignancy and the cyst number/location, although a strong association was shown for cyst size. The presence/size of nodules, and main duct involvement were strongly related with malignancy.

MedicalResearch.com: What is the background for this study?
Response: Artificial pancreas treatment, also referred to as closed loop glucose control, is an emerging treatment option combining a pump and continuous glucose monitoring with a control algorithm to deliver insulin (and potentially glucagon) in a glucose responsive manner. Compared with insulin pumps or sensor augmented pumps, artificial pancreas use can reduce the burden for patients by automatically adjusting the amount of insulin entering the body on the basis of sensor glucose levels. The US Food and Drug Administration has recently approved the first artificial pancreas system for use by people with type 1 diabetes over 14 years of age, based on a safety outpatient study.
