A case of successful transarterial stenting for pseudoaneurysm after pancreaticoduodenectomy.Postpancreaticoduodenectomy (PD) bleeding, which is reported to occur in 5-7%, is a major complication that often causes life-threatening secondary events. A transarterial catheter technique with coil embolization is a widespread procedure that could potentially cause massive hepatic infarction and subsequent sepsis with hepatic abscess, which can be a fatal complication. Here, we introduce a new transarterial technique that uses a hemostat with a stent graft, which successfully rescued a patient had suffered post-PD bleeding.

Feasibility of high-flow nasal oxygen therapy and two-stage sedation during endoscopic hypopharyngeal therapy.Structural disorders of the hypopharynx can lead to dysphagia-related morbidity. Endoscopic therapy in this area, for example, myotomy for Zenker's diverticulum (ZD), has traditionally been performed under general anesthesia (GA). We have developed a two-stage sedation process, which is used along with high-flow nasal oxygen therapy (HFNOT) to facilitate endoscopic hypopharyngeal procedures.

Non-surgical treatment of gastric emphysema with intraabdominal free gas and hepatic portal venous gas: Lessons from a rare case.We herein describe a case of an 83-year-old man who presented with epigastralgia, vomiting, and abdominal distention. The physical abdominal examination revealed mild tenderness. Computed tomography revealed intramural gastric gas spread throughout the stomach, intraabdominal free gas, and hepatic portal venous gas. We diagnosed gastric emphysema with intraabdominal free gas and hepatic portal venous gas. We selected a wait-and-watch approach because physical examination did not show any peritoneal signs, although the radiological examinations showed remarkable findings. As a result, he received conservative therapy with fasting, intravenous infusion of antibiotics, and gastric decompression by nasogastric intubation. The patient was relieved of the symptoms, and follow-up computed tomography showed that all the abnormal gas disappeared soon after the treatment. In conclusion, the intramural gastric gas even with both intraabdominal free gas and hepatic portal venous gas does not always require surgical intervention. In case clinicians including general surgeons and physicians encounter intraabdominal free gas with hepatic portal venous gas, gastric emphysema should be considered in the different diagnosis. Lack of knowledge may lead to misdiagnosis, which may result in unnecessary surgical intervention.

Myopericytoma of the stomach: report of one case and review of literature.Myopericytoma is an uncommon, slow-growing benign tumour of concentrically distributed perivascular myoid cells, that occurs generally in the skin and superficial soft tissues especially in distal extremities. In the visceral organs, it is particularly rare. We provide the first report of this rare entity in the stomach. A 45-year-male presented to an outside hospital because of pharyngalgia and cough 10 days prior. Endoscopic ultrasonography revealed a 0.92 cm × 0.92 cm hypoechoic lesion in the submucosa of sinuses ventriculi. For further diagnosis and treatment, the patient came to our hospital, and underwent endoscopic submucosal excavation (ESE), without adjuvant therapy. Postoperative pathology was myopericytoma. No recurrence was found in the follow-up of 27 months. In conclusion, myopericytoma is a comparatively newly described disease entity approved by the World Health Organization classification for tumours of soft tissue. The present report shows the first case of myopericytoma of the stomachto remind clinicians and pathologists that myopericytoma may be encountered at this location.

Limb-bud and heart as a novel biomarker for gastric intestinal type adenocarcinoma.The present study compared the expression levels of limb-bud and heart (LBH) between gastric intestinal-type adenocarcinoma (GITA) and healthy gastric tissues; with the aim of investigating the possible effect of LBH on the prognosis of patients with GITA and to analyze the associated signaling pathways in GITA. Three Oncomine gastric datasets were utilized for the preliminary prediction of the expression levels of LBH mRNA in GITA and healthy gastric tissues. Gene expression and corresponding clinical data of 163 patients with GITA were downloaded from The Cancer Genome Atlas. Wilcoxon signed rank-sum test was used to distinguish the clinical value of LBH expression in the various clinicopathological features. Subsequently, Kaplan-Meier univariate and Cox multivariate survival analyses were performed to determine the prognostic significance of LBH expression in patients with GITA. Function enrichment analysis was conducted for the co-expression gene of LBH, defined as correlation coefficient r>0.06 and P<0.05 using Pearson's χ test. Bioinformatics data demonstrated that compared with that in the normal gastric mucosa, LBH mRNA expression was dramatically higher in GITA tissues (P<0.05). There were significant relationships between the differential expression levels of LBH and clinicopathological parameters in GITA patients (all p<0.05), including pathological stage T (T3-4 vs. T1-2), lymph node metastasis (no vs. yes), distant metastasis (no vs. yes), histological grade (grade 3 vs. grades 1-2) and tumor stage (stages 3-4 vs. stages 1-2). Additionally, the overall survival and disease-free survival (DFS) of patients in the high expression group were poorer compared with those in the low expression group (P<0.05). Cox multivariate survival analysis indicated that increased LBH expression was an independent predictor of poor DFS prognosis in patients with GITA (P=0.045). In summary, LBH is highly expressed in GITA, which can be used as an independent predictor of poor prognosis in patients with GITA. LBH co-expressed genes are closely associated with GITA tumor migration and metastasis.

Does the Introduction of Alien Species Represent a Sanitary Threat for Native Species? The Case of the Eastern Cottontail in Italy.Introduction of alien species is a well-known threat to biodiversity. Where newly introduced, alien species may pose a risk for the local ecological community by competing for resources or by introducing pathogens. is an American lagomorph introduced into Europe in the second half of 20th century, for hunting. This study evaluated the structure and epidemiological characteristics of the gastrointestinal parasite community in an introduced population of in the Province of Alessandria (Piedmont Region-Italy). Three alien parasites were reported out of 271 animals: in the stomach, in the small intestine, and in the large intestine. All these nematodes are commonly reported in in its natural range, but they represent alien species in Europe. The report of these alien parasites is an example of the unexpected consequences caused by the introduction of non-native vertebrates. The documented introduction of new pathogens may alter the parasite community of the native lagomorphs, with possible long-term effects on local ecological dynamics.

Gastric Microbiome Diversities in Gastric Cancer Patients from Europe and Asia Mimic the Human Population Structure and Are Partly Driven by Microbiome Quantitative Trait Loci.The human gastrointestinal tract harbors approximately 100 trillion microorganisms with different microbial compositions across geographic locations. In this work, we used RNASeq data from stomach samples of non-disease (164 individuals from European ancestry) and gastric cancer patients (137 from Europe and Asia) from public databases. Although these data were intended to characterize the human expression profiles, they allowed for a reliable inference of the microbiome composition, as confirmed from measures such as the genus coverage, richness and evenness. The microbiome diversity (weighted UniFrac distances) in gastric cancer mimics host diversity across the world, with European gastric microbiome profiles clustering together, distinct from Asian ones. Despite the confirmed loss of microbiome diversity from a healthy status to a cancer status, the structured profile was still recognized in the disease condition. In concordance with the parallel host-bacteria population structure, we found 16 human loci (non-synonymous variants) in the European-descendent cohorts that were significantly associated with specific genera abundance. These microbiome quantitative trait loci display heterogeneity between population groups, being mainly linked to the immune system or cellular features that may play a role in enabling microbe colonization and inflammation.

2,4,6-Tribromophenol disposition and kinetics in pregnant and nursing Sprague Dawley rats.2,4,6-Tribromophenol (TBP, CAS No. 118-79-6) is a brominated chemical used as a precursor, flame retardant, and wood antifungal agent. TBP is detected in environmental matrices and biota, including human breast milk, placenta, and serum. To address reports of TBP accumulation in human placenta and breast milk, studies were conducted to characterize TBP disposition and toxicokinetics in timed-pregnant or nursing Sprague Dawley (SD) rats following a single oral dose to the dam. Animals were administered [14C]-TBP (10 μmol/kg, 25 µCi/kg, 4 mL/kg) by gavage on gestation day 12) and 20, or postnatal day 12 and serially euthanized between 15 min and 24 h for collection of blood and tissues from the dam and fetuses/pups. Observed plasma TBP Cmax (3 and 7 nmol/mL) occurred at 15 min in both GD12 and GD20 dams while Cmax (3 nmol/mL) was observed at 30 min for PND12 dams. Concentrations in tissues followed plasma concentrations, with kidneys containing the highest concentrations at 30 min. GD12 litters contained a sustained 0.2-0.3% of the dose (5-9 nmol/litter) between 15 min and 6 h while GD20 fetuses (2-3%) and placentas (0.3-0.5%) had sustained levels between 30 min and 12 h. The stomach contents (∼1 nmol-eq/g, 6-12 h), livers (0.04-0.1 nmol-eq/g) and kidneys (0.1-0.2 nmol-eq/g) of PND12 pups increased over time, indicating sustained exposure via milk. Systemic exposure to TBP and its metabolites occurs in both the directly-exposed mother and the indirectly-exposed offspring and is rapid and persistent after a single dose in pregnant and nursing rats.

Metabarcoding of native and invasive species in stomach contents of Great Lakes fishes.As aquatic invasive species (AIS) proliferate worldwide, a better understanding of their roles in invaded habitats is needed to inform management and introduction prevention strategies and priorities. Metabarcoding of stomach content DNA (scDNA) shows considerable promise in such regard. We thus metabarcoded scDNA from two non-native fish species (alewife (Alosa pseudoharengus) and rainbow smelt (Osmerus mordax)), and three native ones (bloater (Coregonus hoyi), ninespine stickleback (Pungitius pungitius), and slimy sculpin (Cottus cognatus)). Fishes (N = 376) were sampled in spring 2009 and 2010 from 73-128 m depths at three Lake Michigan sites. Four mitochondrial cytochrome oxidase 1 (CO1) primer sets designed to target five potential AIS prey, and a universal aquatic invertebrate CO1 primer set targeting both native and AIS prey were used. Quality controlled prey amplicons were matched to three AIS prey: Bythotrephes longimanus (mean percent frequency occurrence, all samples = 7%), Cercopagis pengoi (5%), and Dreissena rostriformis bugensis (11%). Neither invasive prey Dreissena polymorpha nor Hemimysis anomala were detected. Native prey Leptodiaptomus sicilis, Limnocalanus macrurus, and Mysis diluviana were relatively common in scDNA (respective mean percent occurrences, all samples: 48%, 25%, 42%). Analysis of variation in prey occurrences for sample site, predator species, sample year, sample depth, and predator total length (TL) indicated site and predator species were most important. However, B. longimanus occurrence in scDNA depended upon predator TL, perhaps indicative of its unique defensive spine limiting susceptibility to predation until fishes exceed species-specific gape-based limitations. Our analysis of native and invasive prey species indicated possible indirect AIS impacts such as native predators switching their diet due to AIS-driven losses of preferred native prey. Metabarcoding demonstrated that AIS are integrated components of the offshore Lake Michigan food web, with both native and non-native predators, and both invasive and native prey are affecting species interactions across multiple trophic levels.
