ABSTRACT
INTRODUCTION: The aim of this study was to determine the association of PMH and FH of pancreatic (PDAC) and non-pancreatic cancers with IPMN malignant risk. METHODS: A retrospective review of a prospective database of IPMN patients undergoing resection was performed to assess FH and PMH. RESULTS: FH of PDAC was present in 13% of 362 included patients. Of these, 8% had at least one first degree relative (FDR) with PDAC. The rate of PDAC positive FH in non-invasive versus invasive IPMN patients was 14% and 8%, respectively (p = 0.3). In main duct IPMN patients, FH (44%) and PMH of non-pancreatic cancer (16%) was higher than that seen in branch duct IPMN (FH 29%; PMH 6%; p = 0.004 and 0.008). CONCLUSIONS: FH of PDAC is not associated with IPMN malignant progression. FH and PMH of non-pancreatic cancer is associated with main duct IPMN, the subtype with the highest rate of invasive transformation.

BACKGROUND: Pediatric surgery is one of the most difficult surgical fellowships to obtain. It requires stellar academic credentials and, often, dedicated time pursuing research. It is unknown, however, if pediatric surgeons maintain high academic output as faculty members. We hypothesized that the majority of pediatric surgeons do not pursue robust research activities as faculty, and therefore, over time, their academic productivity decreases. METHODS: Numbers of publications, citations, H-index, and NIH funding rates were determined for 4354 surgical faculty at the top-55 NIH based departments of surgery using websites, Scopus, NIH RePORTER, and Grantome. Continuous variables were compared with ANOVA and post-hoc Bonferroni; categorical variables by χ2 test. p<0.05 was significant. RESULTS: In this dataset, 321 pediatric surgery (PS) faculty represented 7.4% of the cohort. Among PS faculty, 31% were assistant professors, 24% associate professors, 31% full professors and 13% had no academic rank. PS faculty had significantly more publications, a higher H index, and more high level NIH funding early in their careers at the assistant professor level compared to general surgeons. PS faculty at the associate professor level had equivalent high level NIH funding, but lower recentness and academic power compared to general surgeons. Professors of PS rebounded slightly, with only observed deficiencies in number of citations compared to general surgeons. CONCLUSIONS: PS faculty in assistant professor ranks has higher scholarly productivity compared to equivalently ranked general surgeons. Despite some mild academic setbacks in midcareer, pediatric surgeons are able to maintain similar academic productivity to their general surgery colleagues by the time they are full professors. LEVEL OF EVIDENCE: 2.
