BACKGROUND: Sexual dimorphism has been demonstrated after major trauma and hemorrhage shock with protective effects related to female sex or estrogen. Traumatic endotheliopathy is an important component of trauma-induced coagulopathy. Components of endothelial barrier dysfunction include degradation of the endothelial glycocalyx and endothelial cellular injury. Estrogen modulates endothelial function via its membrane and cellular receptors. The effects of estrogen on the vascular endothelial barrier after trauma and hemorrhage shock are, however, unknown...

BACKGROUND: Serum amylase activity greater than the institutional upper limit of normal (hyperamylasemia) on postoperative day 0-2 has been suggested as a criterion to define postoperative acute pancreatitis after pancreatoduodenectomy, but robust evidence supporting this definition is lacking. BACKGROUND: To assess the clinical impact of hyperamylasemia after pancreatoduodenectomy and to define postoperative acute pancreatitis. METHODS: Data of 1,235 consecutive patients who had undergone pancreatoduodenectomy between January 2010 and December 2014 were extracted from a prospective database and analyzed...

BACKGROUND: Thyroid surgeons are offering their patients less aggressive diagnostic and therapeutic management strategies for thyroid nodules and low-risk thyroid cancer in an effort to decrease overdiagnosis and overtreatment of indolent disease. Explaining the rationale for less aggressive management plans requires physicians to be effective communicators. We aimed to assess the communication skills of thyroid surgeons with the Makoul Communication Assessment Tool and to identify risk factors for poor communication...

BACKGROUND: The opioid epidemic prompted reevaluation of surgeons' opioid prescribing practices. This study aimed to demonstrate noninferiority of a staged analgesic regimen after endocrine surgery. METHODS: We conducted a randomized controlled trial comparing analgesic regimens after thyroidectomy and/or parathyroidectomy. Adult patients (≥18 years) were randomized to study arm (A) as-needed acetaminophen + codeine or (B) scheduled acetaminophen/as-needed tramadol...

BACKGROUND: Pulmonary complications are the most common adverse event after injury and second greatest cause of failure to rescue (death after pulmonary complications). It is not known whether readily accessible trauma center data can be used to stratify center-level performance for various complications. Performance variation between trauma centers would allow sharing of best practices among otherwise similar hospitals. We hypothesized that high-, average-, and low-performing centers for pulmonary complication and failure to rescue could be identified and that hospital factors associated with success and failure could be discovered...

BACKGROUND: Tumor-associated tissue eosinophilia (TATE) has been associated with outcomes in a variety of solid tumors; however, its role in breast cancer is not well defined. We hypothesized that tumor-associated tissue eosinophilia is associated with a high mutation and neoantigen load, and we assessed its correlation with cancer outcomes. METHODS: The Cancer Genome Atlas was analyzed for eosinophil signatures in breast cancer specimens. Descriptive analyses were performed, including the tumor-infiltrating cell composition using CIBERSORT, cytolytic activity score, and gene set enrichment analysis...

BACKGROUND: Few studies evaluate the impact of unhealthy alcohol and drug use on the risk and severity of postoperative outcomes after upper gastrointestinal and pancreatic oncologic resections. METHODS: The National Inpatient Sample was queried to identify patients undergoing total gastrectomy, esophagectomy, total pancreatectomy, and pancreaticoduodenectomy between 2012 and 2015. Unhealthy alcohol and drug use was assessed by the International Classification of Diseases, Ninth Revision, and National Inpatient Sample coder designation...

BACKGROUND: In pancreatic cancer, extensive tumor involvement of the mesenteric venous system poses formidable challenges to operative resection. Such involvement can result from cavernous collateral veins leading to increased intraoperative blood loss or long-segment vascular defects of not only just the superior mesenteric vein but also even jejunal/ileal branches. Strategies to facilitate margin-free resection and safe vascular reconstruction in pancreatic surgery are important, particularly because systemic control of the tumor is improving with multi-agent chemotherapy regimens...

BACKGROUND: We applied various machine learning algorithms to a large national dataset to model the risk of postoperative sepsis after appendectomy to evaluate utility of such methods and identify factors associated with postoperative sepsis in these patients. METHODS: The National Surgery Quality Improvement Program database was used to identify patients undergoing appendectomy between 2005 and 2017. Logistic regression, support vector machines, random forest decision trees, and extreme gradient boosting machines were used to model the occurrence of postoperative sepsis...

BACKGROUND: The benefit of removing the splenic lymph nodes in patients with proximal gastric cancer has been controversial. The purpose of our study was to investigate the importance of performing a splenic hilar lymph node dissection without splenectomy in patients undergoing total gastrectomy for gastric cancer. METHODS: From January 2006 to December 2015, we retrospectively reviewed patients who underwent a curative total gastrectomy for gastric cancer. Propensity score matching was used to balance any potential discrepancy of the other covariates between patients with and without splenic hilar lymph node dissection...

Children undergoing congenital cardiac surgery often outgrow the valve implants. These children are thus committed to morbid reoperations for successive exchanges of the vavular implants that they have outgrown. Therefore the holy grail of congenital cardiac surgery is a valve implant that grows with the recipient child. Preserved homografts routinely are used as valve implants, but they do not grow as the child grows because they lose viability during preservation. In contrast, pulmonary autografts and pediatric heart transplants grow with the recipient children...

BACKGROUND: Primary aldosteronism is a common cause of secondary hypertension. Resolution of hypertension and hypokalemia after adrenalectomy for primary aldosteronism is variable. This study examines preoperative factors for persistent hypertension and long-term outcome after laparoscopic adrenalectomy in patients with primary aldosteronism. METHODS: We reviewed all patients who underwent laparoscopic resection for adrenal tumors from 2010 to 2018. Biochemical success was defined as normalization of hypokalemia and the aldosterone-to-renin ratio...
