Hypertriglyceridemia (HTG) aggravates the course of acute pancreatitis (AP). Intestinal barrier dysfunction is implicated in the pathogenesis of AP during which dysbiosis of intestinal microbiota contributes to the dysfunction in intestinal barrier. However, few studies focus on the changes in intestine during HTG-related acute necrotizing pancreatitis (ANP). Here, we investigated the changes in intestinal microbiota and Paneth cell antimicrobial peptides (AMPs) in HTG-related ANP (HANP) in rats. Rats fed a high-fat diet to induce HTG and ANP was induced by retrograde injection of 3...

OBJECTIVES: Intestinal barrier dysfunction plays an important role in acute necrotizing pancreatitis (ANP) and intestinal microbiota dysbiosis was involved in intestinal barrier failure. Paneth cells protect intestinal barrier and are associated with intestinal microbiota. Here, we investigated changes in intestinal microbiota and antimicrobial peptides of Paneth cells in ileum during ANP. METHODS: Rats with ANP were established by retrograde injection of 3.5% sodium taurocholate into biliopancreatic duct and sacrificed at 24h and 48h, respectively...

BACKGROUND: The treatment of people with pancreatic necrosis differs from that of people with oedematous pancreatitis. It is important to know the diagnostic accuracy of serum C-reactive protein (CRP), serum procalcitonin, and serum lactate dehydrogenase (LDH) as a triage test for the detection of pancreatic necrosis in people with acute pancreatitis, so that an informed decision can be made as to whether the person with pancreatic necrosis needs further investigations such as computed tomography (CT) scan or magnetic resonance imaging (MRI) scan and treatment for pancreatic necrosis started...

Ischemic stroke in patients with cancer is thought to be associated with a worse prognosis and might be the initial symptom of an unknown malignancy. However, diagnostic algorithms to reliably identify cancer-associated stroke have not been developed. In this retrospective single-centre analysis, 68 patients with ischemic stroke and an active solid malignancy were identified. Neurological assessment and outcome, cardiovascular risk factors, neuroimaging studies as well as laboratory findings were compared to 68 age- and sex-matched control subjects with ischemic stroke without diagnosis of cancer...

INTRODUCTION: Acute pancreatitis is a disease with an increasing incidence in the Western countries associated with a high mortality depending on severity of disease. Etiology is often biliary or due to alcoholism. Incidence of etiology varies between regions depending on risk-factor prevalence. Several risk scores are available to estimate mortality. The aim of the study is to identify the risk factors most relevant for patients being treated for severe acute pancreatitis in an ICU of a tertiary medical center...

Ribosomopathies are a family of inherited disorders caused by mutations in genes necessary for ribosomal function. Shwachman-Diamond Bodian Syndrome (SDS) is an autosomal recessive disease caused, in most patients, by mutations of the SBDS gene. SBDS is a protein required for the maturation of 60S ribosomes. SDS patients present exocrine pancreatic insufficiency, neutropenia, chronic infections, and skeletal abnormalities. Later in life, patients are prone to myelodisplastic syndrome and acute myeloid leukemia (AML)...

Pancreatic ductal adenocarcinoma (PDAC) has a dismal prognosis. The aggressiveness and therapeutic recalcitrance of this malignancy has been attributed to multiple factors including the influence of an active desmoplastic stroma. How the stromal microenvironment of PDAC contributes to the fatal nature of this disease is not well defined. In the analysis of clinical specimens, we observed diverse expression of the hypoxic marker carbonic anhydrase IX and the lactate transporter MCT4 in the stromal compartment...

BACKGROUND: Recent studies suggest that beta-adrenergic blockers attenuate systemic inflammation and improve survival in sepsis. We investigated whether esmolol can reduce lung injury and modulate inflammatory response in a rat model of severe acute pancreatitis (SAP). METHODS: A taurocholate-induced SAP was used, with or without continuously intravenous pumping of esmolol (15 mg/kg/h). Heart rate and arterial pressure were monitored. Nine hrs after esmolol administration, blood was drawn for blood gas analyses and cytokine (interleukin(IL)-6, tumor necrosis factor (TNF)-α) detections, lungs and pancreata were isolated for measurements of myeloperoxidase (MPO) activity and histological damage...

BACKGROUND: Recent studies showed that Isoquercetin (Iso), a novel extracts of plants and fruits could protect neuronal cells from neurotoxicity and neuro-inflammation. However, its role in acute spinal cord injury (ASCI) have not been elucidated. In the present study, we investigated whether Iso could prevent Tunicamycin (TUN)-induced rat dorsal root ganglion (DRG) neurons from apoptosis and endoplasmic reticulum (ER) stress. METHODS: DRG neurons were pre-treated with different doses of Iso for 24h (h) and then were stimulated with TUN (0...

The CYP24A1 gene encodes a mitochondrial 24-hydroxylase that inactivates 1,25(OH)2 D. Loss-of-function mutations in CYP24A1 cause hypercalcemia, nephrolithiasis and nephrocalcinosis. We describe a woman with CYP24A1 deficiency and recurrent gestational hypercalcemia. Her first pregnancy, at age 20, resulted with the intrauterine demise of twin fetuses. Postpartum, she developed severe hypercalcemia (14 mg/dL), altered mental status, and acute pancreatitis. Her PTH was suppressed (6 pg/mL) and her 1,25(OH)2 D was elevated (165 and 195 pg/mL on postpartum day 1 and 5, respectively)...
