There are now 354 inborn errors of immunity (primary immunodeficiency diseases (PIDDs)) with 344 distinct molecular etiologies reported according to the International Union of Immunological Sciences (IUIS) (Clin Gastroenterol Hepatol 11: p. 1050-63, 2013, Semin Gastrointest Dis 8: p. 22-32, 1997, J Clin Immunol 38: p. 96-128, 2018). Using the IUIS document as a reference and cross-checking PubMed ( ), we found that approximately one third of the 354 diseases of impaired immunity have a gastrointestinal component [J Clin Immunol 38: p...

We develop a mathematical model of a salivary gland acinar cell with the objective of investigating the role of two [Formula: see text] exchangers from the solute carrier family 4 (Slc4), Ae2 (Slc4a2) and Ae4 (Slc4a9), in fluid secretion. Water transport in this type of cell is predominantly driven by [Formula: see text] movement. Here, a basolateral [Formula: see text] adenosine triphosphatase pump (NaK-ATPase) and a [Formula: see text]-[Formula: see text]-[Formula: see text] cotransporter (Nkcc1) are primarily responsible for concentrating the intracellular space with [Formula: see text] well above its equilibrium potential...

The modern clinical practice is characterized by intensive introduction of innovative technologies for improving treatment and diagnostic procedures, minimizing their impact on the patient, complications rate and economic reasons. One of the priorities in this area is both diagnostic and therapeutic endoscopy. The degree of practical use of innovative endoscopic technologies depends on not only the quality of care, but also their economic reasons. Endoscopic treatment has become the method of choice for gastrointestional bleeding, extraction of foreign bodies, obstructive jaundice, polyps of the gastrointestinal tract, achalasia, esophageal strictures, etc...

INTRODUCTION: Although guidelines emphasize that the provision of enteral nutrition (EN) should be as close as the patient's needs, prospective studies question this strategy. OBJECTIVE: To compare the effect of two EN strategies (underfeeding versus full-feeding) on ICU and overall mortality (hospital mortality or 60-day mortality) and length of stay (LOS), duration of mechanical ventilation (MV), infectious complications, and gastrointestional tolerability in ICU patients...

Intestinal iron absorption is highly regulated since no mechanism for iron excretion exists. We previously demonstrated that expression of an intestinal copper transporter (Atp7a) increases in parallel with genes encoding iron transporters in the rat duodenal epithelium during iron deprivation (Am. J. Physiol.: Gastrointest. Liver Physiol., 2005, 288, G964-G971). This led us to postulate that Atp7a may influence intestinal iron flux. Therefore, to test the hypothesis that Atp7a is required for optimal iron transport, we silenced Atp7a in rat IEC-6 and human Caco-2 cells...

BACKGROUND: Bariatric surgery is an effective intervention strategy in obesity, resulting in sustained weight loss and a reduction of comorbidities. Gastroplication, using the articulating circular endoscopic stapler, was recently introduced as a transoral bariatric technique. This procedure reduces gastric volume and induced 34.9 % of excess weight loss in the first year (Paulus et al. Gastrointest Endosc. 81(2):312-20, 3). The aim of the present study was to gain insight in the long-term effects and underlying mechanisms of gastroplication by investigating differences in the genome-wide gastric and duodenal transcriptome before and 1 year after intervention...

Severe congenital neutropenia type IV (SCN IV) is a syndrome of severe neutropenia, cardiac and urogenital defects, prominent superficial veins, facial dysmorphism, failure to thrive (FTT), and intermittent thrombocytopenia, caused by a glucose-6-phosphatase catalytic subunit 3 (G6PC3) gene mutation. SCN IV has been linked to glycogen storage disease type 1b as both disorders involve disruption of the glucose-6-phosphatase/glucose-6-phosphate transporter complex, leading to arrested neutrophil maturation. Emerging evidence suggests that neutrophil function plays an important role in intestinal integrity, evidenced by inflammatory bowel disease in certain neutropenic patients...

BACKGROUND AND STUDY AIMS: Colorectal endoscopic submucosal dissection (ESD) is an attractive method for en bloc resection of larger flat neoplastic lesions. Experience with this method is limited in the Western World. PATIENTS AND METHODS: A total of 182 consecutive flat or sessile colorectal lesions (cecum n = 43; right-sided colon n = 65; left-sided colon n = 11, rectum: n = 63) with a size > 20 mm (mean 41.0 ± 17.4 mm) were resected in 178 patients...

Medical records of the 575 children who underwent gastrointestinal endoscopy outside the operating room were investigated retrospectively. The most frequently used combinations were propofol-midazolam-fentanyl in 83.2% of the procedures and propofol-midazolam in 13.8% of the procedures. 24 (3.4%) of 703 procedures had complications due to sedation anesthesia; 11 had hypoxia and 8 had pain in the injection area. Sedation anesthesia practice provided by an anesthesiologist outside the operating room enables gastrointestional endoscopic procedures to be carried out more safely...

Butyrate, a key short-chain fatty acid metabolite of colonic luminal bacterial action on dietary fiber, serves as a primary fuel for the colonocytes, ameliorates mucosal inflammation, and stimulates NaCl absorption. Absorption of butyrate into the colonocytes is essential for these intracellular effects. Monocarboxylate transporter 1 (MCT1) plays a major role in colonic luminal butyrate absorption. Previous studies (Tan J, McKenzie C, Potamitis M, Thorburn AN, Mackay CR, Macia L. Adv Immunol 121: 91-119, 2014...

Hepatocyte nuclear factor 4 alpha (HNF4α) is known as the master regulator of hepatic differentiation, which regulates over 60% of the hepatocyte specific genes. Recent studies including this (Walesky et al. Am J Physiol Gastrointest Liver Physiol. 304:G26-37, 2013) demonstrated that HNF4α also inhibits hepatocyte proliferation via repression of pro-mitogenic genes. In this study hepatocyte specific HNF4α knockout mice were generated using 2-3 month old HNF4α-floxed mice treated with Cre recombinase under Major Urinary Protein promoter delivered in AAV8 vector (MUP-iCre-AAV8)...

Borderline resectable pancreatic cancer (BRPC) is an evolving diagnostic entity that blurs the distinction between resectable and locally advanced pancreatic cancer (Varadhachary et al. Ann Surg Oncol 13:1035-1046, 2006). Until recently the management of this disease has been poorly defined; however, consensus guidelines have been developed regarding the proper management of this diagnostic entity. Recent studies have shown that if appropriately identified and treated, this subset of disease can have outcomes similar to pancreatic cancer that is defined as resectable (Laurence et al...

The NOTCH pathway is an evolutionarily conserved signalling network, which is fundamental in regulating developmental processes in invertebrates and vertebrates (Gazave et al. in BMC Evol Biol 9:249, 2009). It regulates self-renewal (Butler et al. in Cell Stem Cell 6:251-264, 2010), differentiation (Auderset et al. in Curr Top Microbiol Immunol 360:115-134, 2012), proliferation (VanDussen et al. in Development 139:488-497, 2012) and apoptosis (Cao et al. in APMIS 120:441-450, 2012) of diverse cell types at various stages of their development...

Salmonella enterica subsp. enterica serovar Infantis strains were isolated from broiler chickens from six farms in Japan and the pathogenicity associated with the recently reported 280kbp mega plasmid was examined by possession of the plasmid and histopathology of tissues from these chickens. S. Infantis strains were isolated from 10 of 24 chickens. Phylogenetic, network and Bayesian cluster analyses were used to determine whether these strains were in the previously defined Clusters 1-5. Phylogenetic analysis classified the strains isolated in this study in two groups (Groups A and B)...

Endoscopic insertion of enteral feeding tubes is a major advance in the delivery of nutrition therapy. Since the first report of percutaneous endoscopic gastrostomy (PEG) in 1980 (Gauderer et al. J Pediatr Surg. 15:872-5, 1980), insertion techniques and equipment have been refined and improved. Despite this progress, deep jejunal enteral access remains a difficult procedure, and many endoscopists do not have experience with the techniques of nasojejunal (NJ) placement, percutaneous endoscopic gastrojejunostomy (PEGJ), or direct percutaneous endoscopic jejunostomy (DPEJ) (Shike and Latkany, Gastrointest Endosc Clin N Am...

Sacroiliac joint (SIJ) pain is a common symptom in ankylosing spondylitis (AS). Palisade sacroiliac joint radiofrequency neurotomy (PSRN) is a novel treatment for the SIJ pain. In the current clinical trial, we treated AS patients with significant SIJ pain using PSRN under computed tomography guidance and compared the results with the celecoxib treatment. The current study included 155 AS patients. Patients were randomly assigned to receive PSRN or celecoxib treatment (400 mg/day for 24 weeks). The primary endpoint was global pain intensity in visual analog scale, at week 12...
