Pancreatic β-cell Tcf7l2 deletion or its functional knockdown suggested the essential role of this Wnt pathway effector in controlling insulin secretion, glucose homeostasis, and β-cell gene expression. As the LIM homeodomain protein Isl1 is a suggested Wnt pathway downstream target, we hypothesize that it mediates metabolic functions of Tcf7l2. We aimed to determine the role of Isl1 in mediating the function of Tcf7l2 and the incretin hormone GLP-1 in pancreatic β-cells. Effect of dominant negative TCF7L2 (TCF7L2DN) mediated Wnt pathway functional knockdown on Isl1 expression was determined in βTCFDN mouse islets and in the rat insulinoma cell line INS-1 832/13...

We aimed to determine the microbiology of infected walled-off pancreatic necrosis (WON) in an era of minimally invasive treatment, since current knowledge is based on surgical specimens performed over two decades ago. We retrospectively analyzed a prospectively maintained database of patients who were treated for symptomatic WON using combined endoscopic and percutaneous drainage between 2008 and 2017. Aspirates from WON at initial treatment were evaluated. One hundred eighty-two patients were included with a mean age of 56 of whom 67% were male...

BACKGROUND: Graft preservation continues to be one of the main pillars of pancreas transplantation (PT). Surgical complications, possibly caused or facilitated by organ damage during preservation, continue to occur more frequently after PT than for any other abdominal organ. During the past few years, the Georges Lopez Institute preservation solution IGL-1 has been introduced with satisfactory results for the perfusion and cold storage of abdominal grafts such as kidney and liver. METHODS: Aspects related to 47 PTs with the use of IGL-1 as the only preservation solution performed from January 2012 to September 2017 at Hospital Santa Isabel, Blumenau, Brazil, were retrospectively analyzed...

Gastric gland mucin secreted from pyloric gland cells, mucous neck cells, and cardiac gland cells of the gastric mucosa harbors unique O-glycans carrying terminal α1,4-linked N-acetylglucosamine residues (αGlcNAc), which are primarily attached to the scaffold mucin core protein MUC6. αGlcNAc acts as an antibiotic against Helicobacter pylori (H. pylori), a microbe causing gastric cancer. In addition, mice deficient in A4gnt, which encodes the enzyme α1,4-N-acetylglucosaminyltransferase (α4GnT) that catalyzes αGlcNAc biosynthesis, spontaneously develop gastric differentiated-type adenocarcinoma, even if not infected by H...

Background: Smad3 linker phosphorylation plays essential roles in tumor progression and metastasis. We have previously reported that the mutation of Smad3 linker phosphorylation sites (Smad3-Erk/Pro-directed kinase site mutant constructs [EPSM]) markedly reduced the tumor progression while increasing the lung metastasis in breast cancer. Methods: We performed high-throughput RNA-Sequencing of the human prostate cancer cell lines infected with adenoviral Smad3-EPSM to identify the genes regulated by Smad3-EPSM...

Toxoplasma gondii is the causative parasite of an important worldwide disease. This obligate intracellular parasite can infect and replicate inside any nucleated cells including those of pancreas. Insulin is a hormone secreted by the pancreas and is responsible for controlling blood glucose concentration. Deficiency of insulin production accounts for the occurrence of type-1 diabetes mellitus (T1D). Thus, theoretically, toxoplasmosis could play a possible role in the development of T1D. However, the studies on this theory are still insufficient; therefore, this work was designed...

BACKGROUND: Severe chronic kidney disease (CKD) predicts adverse outcomes in patients undergoing pancreatectomy, but the impact of milder CKD is unknown. Additionally, some authors have suggested that, due to physiologic changes of aging, CKD is over-diagnosed in patients above age 65. METHODS: Patients undergoing pancreatectomy for malignancy from 2005 to 2014 were identified from the National Surgical Quality Improvement Program. Primary outcomes were all-cause mortality and major complication, defined as myocardial infarction, cardiac arrest, stroke, venous thromboembolism, respiratory failure, deep surgical site infection, pneumonia, acute kidney injury, coma > 24 h, or re-operation occurring within 30 days of surgery...

The aim of the present study was to further unravel the pathophysiologic mechanisms of inclusion body hepatitis (IBH). In a first trial, the susceptibility of specific-pathogen-free (SPF) broilers to fowl aviadenovirus (FAdV) infections was investigated. Regardless of viral dose, route of infection, and susceptibility to disease on day 1, the 3-week-old SPF broilers showed resistance to IBH, with no mortality being recorded throughout the experiment. In a second trial, SPF broilers were orally infected at 3 weeks of age with a FAdV-E strain, and their digestive and metabolic processes were monitored...

BACKGROUND & AIMS: The AT-rich interaction domain 1A gene (ARID1A) encodes a protein that is part of the large ATP-dependent chromatin remodeling complex SWI/SNF and is frequently mutated in human pancreatic ductal adenocarcinomas (PDACs). We investigated the functions of ARID1A during formation of PDACs in mice. METHODS: We performed studies with Ptf1a-Cre; KrasG12D mice, which express activated Kras in the pancreas and develop pancreatic intraepithelial neoplasias (PanINs), as well as those with disruption of Aird1a (Ptf1a-Cre; KrasG12D ; Arid1af/f mice) or disruption of Brg1 (encodes a catalytic ATPase of the SWI/SNF complex) (Ptf1a-Cre; KrasG12D ; Brg1f/f mice)...

Hepatitis E virus (HEV) is a significant public health problem that affects almost 20 million individuals annually and cause acute liver injury in 3,5 million. Hepatitis E virus can cause acute, fulminant and chronic hepatitis and has been associated with a range of extrahepatic manifestation. The spectrum of these manifestation is still emerging. Acute pancreatitis and neurological, renal, hematologic, and muscoloskeletal manifestations have been described. Renal injury include membranoproliferative glomerulonephritis with or without cryoglobulinemia, membranous glomerulonephritis and tubular necrosis...

We report a case of a 35-year-old male with a pancreatic pseudocyst, who developed bilateral endogenous endophthalmitis, 4 days after surgical drainage of the pseudocyst. Bacterial cultures of the pancreatic drain fluid and the vitreous tap showed the growth of Klebsiella pneumoniae. The cultured organism was resistant to all the tested antibiotics except colistin. Intravenous colistin was instituted and three injections of intravitreal colistin were given in the left eye of the patient. Complete resolution of infection was seen and visual acuity of 6/6 was regained in both eyes, which was maintained at 4-month follow-up...

Surgical Site Infections (SSI) represent an onerous burden on our health-care system. This study was undertaken to determine the impact of a protocol aimed at reducing SSIs on the frequency and cost of SSIs after abdominal surgery. Beginning in 2013, 811 patients undergoing gastrointestinal operations were prospectively followed. In 2014, we initiated a protocol to reduce SSIs. SSIs were monitored before and after protocol implementation, and differences in SSI incidence and associated costs were determined...

A fever, or increased body temperature, is a symptom of inflammation, which is a complex defence reaction of the organism to pathogenic infections. After pathogens enter the body, immune cells secrete a number of agents, the functions of which stimulate the body to develop a functional immune and fever response. In mammals it is known that PGE2 is the principal mediator of fever. The extent to which PGE2 and other pro-inflammatory cytokines such as TNF-α, IL-6, or IL-1β could be involved in the induction of behavioural fever in fish remains to be clarified...

BACKGROUND: Postoperative pancreatic fistula (POPF) is a severe complication of the pancreaticoduodenectomy (PD). Recently, we introduced a method of suspender pancreaticojejunostomy (PJ) to the PD. In this study, we retrospectively analyzed various risk factors for complications after PD. We also introduced and assessed the suspender PJ to demonstrate its advantages. METHODS: Data from 335 patients with various periampullary lesions, who underwent the Whipple procedure (classic Whipple procedure or pylorus-preserving) PD by either traditional end-to-side invagination PJ or suspender PJ, were analyzed...

Gut microbiota is key to the development and modulation of the mucosal immune system. It plays a central role in several physiological functions, in the modulation of inflammatory signaling and in the protection against infections. In healthy states, there is a perfect balance between commensal and pathogens, and microbiota and the immune system interact to maintain gut homeostasis. The alteration of such balance, called dysbiosis, determines an intestinal bacterial overgrowth which leads to the disruption of the intestinal barrier with systemic translocation of pathogens...

Clinical tolerance without immunosuppression has now been achieved for organ transplantation, and its scope will likely continue to expand. In this context, a previously understudied and now increasingly relevant area is how microbial infections might affect the efficacy of tolerance. A highly prevalent and clinically relevant posttransplant pathogen is cytomegalovirus (CMV). Its impact on transplantation tolerance and graft outcomes is not well defined. Employing a mouse model of CMV (MCMV) infection and allogeneic pancreatic islet transplantation in which donor-specific tolerance was induced by infusing donor splenocytes rendered apoptotic by treatment with ethylenecarbodiimide, we investigated the effect of CMV infection on transplantation tolerance induction...
