Hepaticogastrostomy versus hepaticogastrostomy with antegrade stenting for malignant biliary obstruction: a systematic review and meta-analysis.

Background: Combining antegrade stenting (AGS) and hepaticogastrostomy (HGS) is an increasingly used endoscopic ultrasound-guided intervention when stenting by endoscopic retrograde cholangiopancreatography is impossible.

Objectives: We comprehensively assessed the benefits and downsides of combined AGS and HGS (HGS procedure with AGS, HGAS).

Data Sources And Methods: From 788 HGS and 295 HGAS cases, a random-effects meta-analysis was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol.

The risk of developing splanchnic vein thrombosis in acute pancreatitis increases 3 days after symptom onset: A systematic review and meta-analysis.

Background: Splanchnic vein thrombosis is a complication of acute pancreatitis (AP) and is likely often underdiagnosed.

Objectives: We aimed to understand the time course and risk factors of splanchnic vein thrombosis in the early phase of AP.

Methods: A systematic search was conducted using the PRISMA guidelines (PROSPERO registration CRD42022367578).

Fatty Pancreas Is a Risk Factor for Pancreatic Cancer: A Systematic Review and Meta-Analysis of 2956 Patients.

Pancreatic cancer (PC) is one of the most lethal cancers worldwide. Recently, fatty pancreas (FP) has been studied thoroughly, and although its relationship to PC is not fully understood, FP is suspected to contribute to the development of PC. We aimed to assess the association between PC and FP by conducting a systematic review and meta-analysis.

Early prediction of acute necrotizing pancreatitis by artificial intelligence: a prospective cohort-analysis of 2387 cases.

Pancreatic necrosis is a consistent prognostic factor in acute pancreatitis (AP). However, the clinical scores currently in use are either too complicated or require data that are unavailable on admission or lack sufficient predictive value. We therefore aimed to develop a tool to aid in necrosis prediction.

Initial Renal Function (eGFR) Is a Prognostic Marker of Severe Acute Pancreatitis: A Cohort-Analysis of 1,224 Prospectively Collected Cases.

Acute pancreatitis (AP) is a life-threatening disease. We aimed to explore the prognostic relevance of renal function based on estimated glomerular filtration rate (eGFR). A prospective registry of AP patients was established by the Hungarian Pancreatic Study Group.

Glucose levels show independent and dose-dependent association with worsening acute pancreatitis outcomes: Post-hoc analysis of a prospective, international cohort of 2250 acute pancreatitis cases.

Background: Metabolic risk factors, such as obesity, hypertension, and hyperlipidemia are independent risk factors for the development of various complications in acute pancreatitis (AP). Hypertriglyceridemia dose-dependently elicits pancreatotoxicity and worsens the outcomes of AP. The role of hyperglycemia, as a toxic metabolic factor in the clinical course of AP, has not been examined yet.

Early occurrence of pseudocysts in acute pancreatitis - A multicenter international cohort analysis of 2275 cases.

Background: Pseudocysts being the most frequent local complications of acute pancreatitis (AP) have substantial effect on the disease course, hospitalization and quality of life of the patient. Our study aimed to understand the effects of pre-existing (OLD-P) and newly developed (NEW-P) pseudocysts on AP.

Methods: Data were extracted from the Acute Pancreatitis Registry organized by the Hungarian Pancreatic Study Group (HPSG).

Recurrent acute pancreatitis induced by 5-ASA and azathioprine in ulcerative colitis.

Drug-induced acute pancreatitis (DIAP) is an often-neglected entity where the disorder is the consequence of the toxic effects of various agents applied to treat potentially life-threatening conditions, such as inflammatory bowel disease. Here, we present the case of a male patient with ulcerative colitis with a history of two episodes of recurrent acute pancreatitis. After excluding other potential causes, we suspected DIAP since the patient received 5-aminosalycilate (5-ASA) prior to the first episode and, one year later, azathioprine (AZA) prior to the second episode.

EarLy Elimination of Fatty Acids iN hypertriglyceridemia-induced acuTe pancreatitis (ELEFANT trial): Protocol of an open-label, multicenter, adaptive randomized clinical trial.

Introduction: Acute pancreatitis (AP) is a life-threatening inflammatory disease, with no specific pharmacological treatment. However, concerning some etiologies, early specific intervention (such as ERCP in biliary AP) has proven to be remarkably beneficial. Hypertriglyceridemia (HTG) induces severe pancreatic damage by several direct (cellular damage) and indirect (deterioration of microcirculation) mechanisms.

Observational longitudinal multicentre investigation of acute pancreatitis (GOULASH PLUS): follow-up of the GOULASH study, protocol.

Background: Acute pancreatitis (AP) is an inflammatory condition that can lead to late consequences. Recurrent AP (RAP) develops in 20% of patients and chronic pancreatitis (CP) occurs in 7%-12.8%.

[A diagnostic challenge: paraduodenal pancreatitis. ].

The paraduodenal, or groove pancreatitis is a lesser-known type of chronic pancreatitis, often mimicking malignancy, hence resulting in serious differential diagnostic challenges. Herein we report two cases of this entity. Both required analysis of the surgical specimen in order to ensure the diagnosis due to inadequate preoperative histological sampling and a vague clinical presentation.

[Acute appendicitis in a patient with perianal Crohn's disease receiving infliximab].

The differential diagnosis of acute abdominal complaints is challenging in Crohn's disease. This is particularly true in patients in remission induced by biological therapy. In addition to the acute relapse of Crohn's disease, other common causes, such as acute appendicitis exhibiting similar and often atypical course, should be taken into consideration irrespective of the age.

High versus low energy administration in the early phase of acute pancreatitis (GOULASH trial): protocol of a multicentre randomised double-blind clinical trial.

Introduction: Acute pancreatitis (AP) is an inflammatory disease with no specific treatment. Mitochondrial injury followed by ATP depletion in both acinar and ductal cells is a recently discovered early event in its pathogenesis. Importantly, preclinical research has shown that intracellular ATP delivery restores the physiological function of the cells and protects from cell injury, suggesting that restoration of energy levels in the pancreas is therapeutically beneficial.

The in vitro and in ovo effects of environmental illumination and temperature on the melatonin secretion from the embryonic chicken pineal gland.

Pineal glands of chicken embryos were placed into a perifusion system for 4 days. The pineal glands were illuminated or exposed to elevated temperature for 8 or 12 h during the in vitro experiment and/or in ovo. Both daily illumination and repeated elevations of environmental temperature transitionally inhibited melatonin release before, and controlled the phase of melatonin rhythm after, the 17th day of embryonic life (E17).

Effects of PACAP on the circadian changes of signaling pathways in chicken pinealocytes.

Pituitary adenylate cyclase-activating polypeptide (PACAP) is involved in the regulation of circadian rhythms. In mammals, the brain's biological clock is the suprachiasmatic nucleus, receiving photic information from the retina through the retinohypothalamic pathway, where PACAP is the main cotransmitter of glutamate. The primary conductor of circadian rhythms of birds is the pineal gland.

The effects of environmental illumination on the in vitro melatonin secretion from the embryonic and adult chicken pineal gland.

The aim of this study was to monitor the changes in the pattern of the in vitro melatonin (MT) secretion under reversed illumination cycles with low intensity of light during photo phase. Although light is known to be one of the major synchronizing factors of the circadian MT rhythm in birds, there are no data available on the limits of direct light sensitivity of the avian pinealocytes. In our experiments, MT secretion from adult or from embryonic chicken pineal glands was monitored in a perifusion system for 4 days.

Development of the rhythmic melatonin secretion in the embryonic chicken pineal gland.

In order to elucidate details on the development of the circadian clock, the effects of light on the in vitro melatonin (MT) release and the presence of mRNAs of several clock genes in the embryonic chicken pineal gland were investigated. Chicken embryos of various developmental stages were exposed to stimuli of light in vitro in dynamic, four day long bioassay (perifusion). MT secretion and mRNA levels of Cry1, Cry2, Clock and Bmal2 clock genes were determined.

The effects of periodic alteration of the temperature on the rhythmic melatonin release of explanted chicken pineals.

The melatonin rhythm of cultured chicken pineal cells can be synchronized by cyclic environmental effects. Unlike the effects of light on the melatonin secretion, those of the temperature changes are much less known. Similarly, only a few data are available on the interactions between environmental illumination and periodic temperature changes and on the sensitivity of the pineal gland to temperature changes in different ages of animals.

Development of the circadian melatonin rhythm and the effect of PACAP on melatonin release in the embryonic chicken pineal gland. An in vitro study.

Pituitary adenylate cyclase activating polypeptide (PACAP) has been shown to participate in modulation of circadian rhythm and to stimulate melatonin (MT) secretion in both the rat and chicken pineal glands. In contrast to mammals, the main regulator of circadian rhythm in birds is the pineal gland, which begins its rhythmic MT production already during embryonic life. In the present study, we investigated the development of MT secretion in explanted embryonic chicken pineals and their responsiveness to PACAP in a perifusion system.
