BACKGROUND: Fear of medical liability is a major driver for broad administration of perioperative prophylactic anticoagulation, despite the persistently low rates of clinically symptomatic venous thromboembolism events (VTE) postoperatively. This study was undertaken to evaluate the medicolegal landscape of perioperative VTE and its pharmaceutical prophylaxis. METHODS: The Westlaw legal database was retrospectively searched for verdicts in medical professional liability cases in the United States between 2009 and 2020...

BACKGROUND: Colon cancer survival is dependent on metastatic potential and treatment. Large RNA-sequencing data sets may assist in identifying colon cancer-specific biomarkers to improve patient outcomes. OBJECTIVE: This study aimed to identify a highly specific biomarker for overall survival in colon adenocarcinoma by using an RNA-sequencing data set. DESIGN: Raw RNA-sequencing and clinical data for patients with colon adenocarcinoma (n = 271) were downloaded from The Cancer Genome Atlas...

Colon adenocarcinoma is a common cause of cancer-related deaths worldwide. Epithelial-mesenchymal transition is a major regulator of cancer metastasis, and increased understanding of this process is essential to improve patient outcomes. Long non-coding RNA (lncRNA) are important regulators of carcinogenesis. To identify lncRNAs associated with colon carcinogenesis, we performed an exploratory differential gene expression analysis comparing paired colon adenocarcinoma and normal colon epithelium using an RNA-sequencing data set...

Hepatocellular carcinoma (HCC), the most common primary hepatic malignancy worldwide, is the second leading cause of cancer-related death. Underlying liver dysfunction and advanced stage of disease require treatments to be optimally timed and implemented to minimize hepatic parenchymal damage while maximizing disease response and quality of life. Locoregional therapies (LRTs) such as trans-arterial chemo- and radio-embolization remain effective for intermediate liver-only and advanced HCC disease (i.e., Barcelona-Clinic liver cancer stages B and C) not amendable to primary resection or ablation...

BACKGROUND: Anal squamous cell carcinoma incidence is increasing nationally and, more so, in Kentucky. Squamous cell carcinoma of the anus unexpectedly identified at hemorrhoidectomy pathologic evaluation is not uncommon. We hypothesized this is occurring more frequently and sought to evaluate its impact on outcomes. METHODS: The Kentucky Cancer Registry, a premier population database, was queried for all squamous cell carcinoma of the anus cases between 2007 and 2016...

Immune dysfunction can occur during sepsis or following major trauma. Decreased monocyte HLA-DR expression and cytokine responses are associated with mortality. Recent studies have shown that adaptive immune system defects can also occur in such patients, characterised by increased PD-L1 expression and associated T-cell anergy. The aim of this study was to determine the effects of an immune adjuvant, interferon-gamma, on monocyte PD-L1 expression and T-cell activation in an ex-vivo human whole blood model of infection...

Following major trauma, sepsis or surgery, some patients exhibit an impaired monocyte inflammatory response that is characterized by a decreased response to a subsequent bacterial challenge. To investigate this poorly understood phenomenon, we adopted an in-vitro model of endotoxin tolerance utilising primary human CD14 + monocytes to focus on the effect of impairment on IκKα/β, a critical part of the NFκB pathway. Impaired monocytes had decreased IκKα mRNA and protein expression and decreased phosphorylation of the IκKα/β complex...

BACKGROUND: Whether the risk of venous thromboembolism (VTE) may be reduced by preoperative administration of prophylactic heparin is unknown. We hypothesized that timing of heparin administration does not significantly alter the incidence of VTE in pancreatic surgery. METHODS: An analysis was conducted using data from Massachusetts General Hospital's National Surgical Quality Improvement Program from 2012 to 2017. All patients admitted for elective pancreatic resection were included...

BACKGROUND: Severe injury can lead to immune dysfunction and predispose patients to infection and death. Micro-RNAs regulate gene expression and may act as biomarkers for susceptibility to infection. The aim of this study was to examine the temporal and differential expression of previously identified dysregulated micro-RNAs in patients with severe injury. METHODS: Fourteen severely injured patients requiring transfusion were enrolled prospectively in this study approved by our institutional review board...

BACKGROUND: In January 2014, Kentucky expanded Medicaid coverage to include all individuals and families with incomes up to 33% above the federal poverty line. This study evaluated the early impact of Medicaid expansion on some aspects of the quality of breast cancer care in Kentucky. STUDY DESIGN: The Kentucky Cancer Registry was queried for all women aged 20 to 64 years diagnosed with breast cancer between 2011 and 2016. Demographic, tumor, and treatment characteristics were assessed for each year during this interval...

This study focuses on impaired monocyte function, which occurs in some patients after trauma, major elective surgery, or sepsis. This monocyte impairment increases the risk of secondary infection and death. We aimed to determine the influence IκK-16 had on monocytes using an ex-vivo model of human monocyte impairment. We included the effects of the well-studied comparators interferon-gamma (IFN-γ) and granulocyte-macrophage colony-stimulating factor (GM-CSF) on impaired monocytes. Primary human monocytes were stimulated with 10ng/mL of lipopolysaccharide (LPS) for 16h and then challenged with 100ng/mL LPS to assess the monocyte inflammatory response...

This reflection retraces the evolution of early followers and leaders. Social change and early contributions set the stage for the current Association for Academic Surgery. Perhaps the most important contribution was Dr. George Zuidema's theme of inclusiveness. AAS was a decade ahead of its time in that regard.
