Background: The objective of this study was to determine whether cyclin E overexpression defines an etiologically distinct subgroup of ovarian cancer. Methods: We analyzed data from 538 epithelial ovarian cancer cases and 629 controls enrolled in a populationbased case-control study. Cyclin E protein overexpression was assessed using immunohistochemistry. Case-control and case-case comparisons were done to evaluate the relationship between cyclin E overexpression and epidemiologic risk factors. Logistic regression models were used to estimate odds ratios (OR) and 95% confidence intervals (95% CI) while adjusting for potential confounders. Results: Case-control comparisons showed ovarian cancers with and without cyclin E overexpression have different associations with several epidemiologic risk factors. A dose-response relationship was observed

Craniosynostosis is a congenital cranial malformation involving premature fusion of cranial sutures. Indications for surgical repair of craniosynostosis include elevation of intracranial pressure, which can result in impaired vision and mental disability, as well as correction of abnormal skull shape. Resorbable plating systems have become the preferred technique for bony fixation in the repair of craniosynostosis. Multiple studies demonstrate the safety and low complication rate of resorbable plating systems. However, there is no consensus on which plating system is superior for patient outcomes. This study aims to investigate how the polymer composition of resorbable plating systems utilized in cranial vault reconstruction contributes to wound healing complications. A retrospective chart review was performed at the institution between January 1, 2005 and December 31, 2015. About 202 patients who underwent surgical repair of craniosynostosis were identified. The results showed that patients receiving the Biomet Lactosorb plating system were over twice as likely to have a wound complication within a year of surgery compared to other plating systems used at the institution. Wound complications continued to occur in the Biomet Lactosorb group at ≥180 days after surgery, whereas complications among the other plating systems occurred ≤80 days postoperatively. Half of all patients with wound complications had to undergo reoperation. These data demonstrate the effect of unique polymer compositions on wound healing, and will help to guide future clinical practice and industry development of resorbable plating systems.
