The aim of the present study was to investigate the effect of curcumin on acute renal injury in a rat model of severe acute pancreatitis (SAP). A SAP model with acute kidney injury was established in rats by retrograde injection of 5% sodium taurocholate into the pancreatic duct. The serum amylase, creatinine (Cr) and blood urea nitrogen (BUN) levels in rats were measured. Hematoxylin and eosin staining was used to assess pancreatic and renal histological changes. Serum tumor necrosis factor (TNF)-α and interleukin (IL)-6 levels were measured using ELISA kits...

High density lipoprotein cholesterol (HDL-C) has been reported as a significant indicator of systemic inflammation. The association underlying HDL-C and persistent organ failure (POF), pancreatic necrosis (PNec) and mortality in acute pancreatitis (AP) has not been evaluated. From 2007 to 2016, consecutive AP patients with admission lipid profiles assessment were included in this study. The association of HDL-C value and other lipids with outcomes was explored with Cox proportional regression models, which were adjusted for confounding factors...

OBJECTIVES: The minimally invasive step-up approach for treatment of walled off necrosis (WON) involves drainage followed by later necrosectomy as needed, and is superior to primary surgical necrosectomy. Reported series of endoscopic transluminal necrosectomy include highly selected patients. We report outcomes of a large series of patients with WON managed by an algorithm based on an endoscopically centered step-up approach. METHODS: Consecutive patients with necrotizing pancreatitis from 2009 to 2014, with intervention only for infected or persistently symptomatic WON...

Inflammatory and fibrotic events that drive chronic pancreatitis (CP) are likely orchestrated via signaling of soluble cytokines and chemokines systemically and within the pancreas. However, a comprehensive summary of the expression of such factors during CP has not been reported to date. This information is important given continued interest in targeting cytokines that influence CP pathogenesis. Reported data on the expression change of soluble immunomodulatory factors in human CP patients were identified via a literature search using a single search term...

Infectious pancreatic necrosis virus (IPNV) has been isolated annually since 1987 from salmonids without clinical signs at coastal fish farms in Finland. In the inland area, viral isolations were rare until 2012, when IPNV was detected at several freshwater fish farms. Between 2013 and 2015, the infection spread and IPNV was continuously isolated from several farms, both inland and on the coast. The aim of this study was to genetically characterise the IPNV isolates collected from Finnish coastal and inland fish farms over the last 15 years, and to detect genetic changes that may have occurred in the virus populations during the study period...

BACKGROUND AND STUDY AIMS:  Walled-off pancreatic necrosis (WOPN) represents the major risk factor for sepsis-related multiple organ failure. Surgical debridement is an invasive approach associated with high rates of adverse events (AEs) and death. As an alternative, endoscopic ultrasound-guided cysto-gastro-anastomosis has emerged as an effective treatment for WOPNs. Recently a new dedicated-lumen apposing metal stent (LAMS) has been used with satisfactory results in treating peri-pancreatic fluid collections, including WOPNs...

We report a case of a 56-year-old woman who presented with worsening abdominal pain located in the left upper quadrant together with abdominal distention, nausea and anorexia. One month prior to this admission, she had presented and had been diagnosed with concurrent acute pancreatitis and rapidly expanding abdominal aortic aneurysm. The aneurysm was prioritised over the pancreatitis and she underwent uncomplicated endovascular repair. Cross-sectional imaging was consistent with infected pancreatic necrosis and also revealed a large collection located in the anterior pararenal space with extensive gas formation...

BACKGROUND & AIMS: Induction of non-apoptotic cell death could be an approach to eliminate apoptosis-resistant tumors. We investigated necroptosis-based therapies in mouse models of pancreatic ductal adenocarcinoma cancer (PDAC). METHODS: We screened 273 commercially available kinase inhibitors for cytotoxicity against a human PDAC cell line (PANC1). We evaluated the ability of the aurora kinase inhibitor CCT137690 to stimulate necroptosis in PDAC cell lines (PANC1, PANC2...

Inflammation is increasingly thought to be associated with diabetes; however, only a few inflammation markers have been assessed concurrently in relation to history of diabetes. In the most comprehensive evaluation of inflammation markers and diabetes to date using a Luminex bead-based assay, we measured 78 inflammation-, immune-, and metabolic-related markers detectable in at least 10% of serum samples collected from participants from the Prostate, Lung, Colorectal and Ovarian Cancer (PLCO) screening trial (n = 1,814)...

OBJECTIVE: Hypoxia is known to induce pancreatic beta cell dysfunction and apoptosis. Changes in Programmed Cell Death Gene 4 (PDCD4) expression have previously been linked with beta cell neogenesis and function. Our aim was to investigate the effects of hypoxia on cell viability, PDCD4 expression and subcellular localisation. METHODS: MIN6 beta cells and ARIP ductal cells were exposed to 1% (hypoxia) or 21% O2 (normoxia) for 12 or 24 hours. MTT assay, HPI staining, scanning electron microscopy, western blotting and immunocytochemistry analyses were performed to determine the effect of hypoxia on cell viability, morphology and PDCD4 expression...

INTRODUCTION: There are new concepts and developments in the diagnosis and management of acute pancreatitis. Current evidence suggests that there is no role of prophylactic antibiotics use in acute pancreatitis. However, it is still a common practice to administer prophylactic antibiotics in a country like Nepal. So, we have conducted a study in mild and moderately severe acute pancreatitis to study the efficacy of prophylactic antibiotics. METHODS: A case control study was conducted among 76 patients comparing efficacy of prophylactic antibiotics versus no antibiotics in patients with mild and moderately severe acute pancreatitis...

To assess the association between the clinical parameters within 48 hours of admission and the occurrence of infected pancreatic necrosis (IPN) during the late phase of necrotizing pancreatitis (NP).All patients were divided into 2 groups, the IPN and non-IPN groups. The clinical data were retrospectively analyzed. Univariate and multivariate logistic regression analyses were performed to evaluate the relationship between clinical parameters and IPN secondary to NP. The performance of each independent variable was plotted by the receiver-operating characteristic (ROC) curve...

Infectious pancreatic necrosis virus (IPNV) is a common pathogen of rainbow trout (Oncorhynchus mykiss) in Turkey. We found that 455 of 1,676 sample pools tested were IPNV positive. Positive samples were found in all geographical regions where sampling was conducted. Sequence and phylogenetic analyses of VP2 from 30 isolates representing all regions showed that the viruses were highly similar in sequence and grouped within Genogroup 5 (serotype Sp-A2). No correlations between sequences, sampling sites or geographical origins were identified...

The infectious pancreatic necrosis virus (IPNV) is a salmonid pathogen that causes significant economic losses to the aquaculture industry. IPNV is a non-enveloped virus containing two uncapped and non-polyadenylated double strand RNA genomic segments, RNA-A and RNA-B. The viral protein Vpg is covalently attached to the 5' end of both segments. There is little knowledge about its viral cycle, particularly about the translation of the RNAs. Through experiments using mono and bicistronic reporters, in this work we show that the 120-nucleotide-long 5'-UTR of RNA-A contains an internal ribosome entry site (IRES) that functions efficiently both in vitro and in salmon cells...

BACKGROUND: Wandering spleen is a rare clinical entity caused by absence of the spleen's peritoneal attachments, allowing the spleen to move freely within the peritoneal cavity [1]. This disease is most commonly seen in children and young women [1, 2]. Affected individuals are predisposed to complications including splenic torsion, splenic infarction, and pancreatic necrosis [3, 4]. Patients may present with constipation, an abdominal mass, swelling, or acute abdominal pain if splenic torsion has occurred [4]...
