A comparative analysis of robotic versus laparoscopic total pancreatectomy: insights from the National Cancer Database.

Total pancreatectomy is a complex procedure used in the management of pancreatic cancer. While minimally invasive techniques have been increasingly adopted, limited data exist comparing robotic total pancreatectomy (RTP) and laparoscopic total pancreatectomy (LTP). This study evaluates the utilization, short- and long-term outcomes of RTP and LTP using the National Cancer Database.

National adoption of neoadjuvant chemotherapy: paradigm shift in the treatment of pancreatic cancer.

Background: The historical standard of care in treating operable pancreatic cancer via upfront surgery has been challenged recently using a neoadjuvant approach. The aim of the study is to examine the national practice patterns in the management of pancreatic cancer with an emphasis on the trends of neoadjuvant systemic therapy use.

Methods: This is a cross-sectional time-series study using the National Cancer Database from 2006 to 2019.

Dysregulation of miR-21-associated miRNA regulatory networks by chronic ethanol consumption impairs liver regeneration.

Impaired liver regeneration has been considered as a hallmark of progression of alcohol-associated liver disease. Our previous studies demonstrated that in vivo inhibition of the microRNA (miRNA) miR21 can restore regenerative capacity of the liver in chronic ethanol-fed animals. The present study focuses on the role of microRNA regulatory networks that are likely to mediate the miR-21 action.

Integrated Multiomics Reveals Glucose Use Reprogramming and Identifies a Novel Hexokinase in Alcoholic Hepatitis.

Background & Aims: We recently showed that alcoholic hepatitis (AH) is characterized by dedifferentiation of hepatocytes and loss of mature functions. Glucose metabolism is tightly regulated in healthy hepatocytes. We hypothesize that AH may lead to metabolic reprogramming of the liver, including dysregulation of glucose metabolism.

Hepatic lipocalin 2 promotes liver fibrosis and portal hypertension.

Advanced fibrosis and portal hypertension influence short-term mortality. Lipocalin 2 (LCN2) regulates infection response and increases in liver injury. We explored the role of intrahepatic LCN2 in human alcoholic hepatitis (AH) with advanced fibrosis and portal hypertension and in experimental mouse fibrosis.

Reduced hybrid/complex N-glycosylation disrupts cardiac electrical signaling and calcium handling in a model of dilated cardiomyopathy.

Dilated cardiomyopathy (DCM) is the third most common cause of heart failure, with ~70% of DCM cases considered idiopathic. We showed recently, through genetic ablation of the MGAT1 gene, which encodes an essential glycosyltransferase (GlcNAcT1), that prevention of cardiomyocyte hybrid/complex N-glycosylation was sufficient to cause DCM that led to heart failure and early death. Our findings are consistent with increasing evidence suggesting a link between aberrant glycosylation and heart diseases of acquired and congenital etiologies.

In Vivo Zonal Variation and Liver Cell-Type Specific NF-κB Localization after Chronic Adaptation to Ethanol and following Partial Hepatectomy.

NF-κB is a major inflammatory response mediator in the liver, playing a key role in the pathogenesis of alcoholic liver injury. We investigated zonal as well as liver cell type-specific distribution of NF-κB activation across the liver acinus following adaptation to chronic ethanol intake and 70% partial hepatectomy (PHx). We employed immunofluorescence staining, digital image analysis and statistical distributional analysis to quantify subcellular localization of NF-κB in hepatocytes and hepatic stellate cells (HSCs).
