It is unclear if sequencing has additional benefits over routine diagnostic methods for Helicobacter pylori testing.<br /><br /> We enrolled Mongolian volunteers with dyspepsia. Using routine diagnostic methods, positive H.pylori was defined as positive results on histology/immunohistochemistry, culture, rapid urease test, or serology; negative H.pylori was defined by negative results from all these tests. We performed 16S rRNA sequencing on gastric biopsy specimens and calculated cutoffs for operational taxonomic units (OTUs) and relative abundance (RA) to define positive results using ROC curves.<br /><br /> We examined 161 individuals with a mean age of 43.6years, and 64.6% were women. Using routine diagnostic methods, 122 (75.8%) participants were H.pylori positive, the sensitivity and specificity for 16S rRNA sequencing were 94.3% and 82.1% or 93.4% and 82.1% when cutoff values were set to 1113 (OTU number) or 4.4% RA, resr microbiota.<br /><br /> Nonalcoholic steatohepatitis (NASH) is a risk factor for nonvirus-related hepatocellular carcinoma, which is increasing in prevalence. The aim of this study was to clarify the clinical application of fucosylated alpha-fetoprotein (AFP-L3) in the process of nonalcoholic fatty liver (NAFL) disease development.<br /><br /> Serum samples from 115 diabetes mellitus (DM), 36 NAFL, and 119 NASH patients were analyzed for AFP-L3 expression using raw data of a micro total analysis system. These data were then compared with the clinical characteristics of the patients. A validation study was also undertaken with 55 samples (17 NAFL and 38 NASH).<br /><br /> Trace amounts of AFP-L3 were detected in 3.5%, 16.7%, and 58.0% of patients with DM, NAFL, and NASH, respectively. The odds ratio of AFP-L3 positivity for the diagnosis of NASH in multivariate analysis was 9.81 (95% confidence interval,3.77-25.5). The rates in patients without fibrosis or with stage 1, stage 2, stage 3, and stage 4 fibrosis were 14.7%, 31.3%, 63.0%, 86.2%, and 100%, respectively. The rates were significantly increased according to the advancement of liver fibrosis (p&lt;0.001); however, no difference in the positive rate of AFP-L3 was observed between patients with and without fatty livers and between patients with normal and abnormal transaminase. The same relationship was also observed in the validation cohort.<br /><br /> Abnormal fucosylation of AFP occurred in patients with NASH, so it could be useful for the screening of NASH in patients with DM, as well as for the differential diagnosis of NASH and the evaluation of fibrosis.<br /><br />Abnormal fucosylation of AFP occurred in patients with NASH, so it could be useful for the screening of NASH in patients with DM, as well as for the differential diagnosis of NASH and the evaluation of fibrosis.<br /><br /> The role of neoadjuvant therapy (NT) for ampullary carcinoma (AC) has not been clearly established.<br /><br /> Patients who underwent pancreatoduodenectomy for AC between 2004 and 2016 were identified in the National Cancer Database. Overall survival (OS) was compared between those who received NT before resection and those who underwent surgery first (SF). Propensity score matching (PSM) was performed using age, pathologic T and N stage, and tumor differentiation.<br /><br /> Among 8688 patients with AC, 175 (2.0%) received NT before surgery. While patients who received NT were younger (p = .022) and more likely to have nodal metastasis (43.3% vs. 35.1%, p &lt; .001), there was no difference in OS on univariate (43 vs. 33 months; hazard ratio [HR] 1.10, 95% confidence interval [CI] 0.88-1.37, p = .401) or multivariate (HR 1.09, 95% CI 0.88-1.36, p = .416) analysis between groups. After PSM, there remained no difference in OS between NT or SF groups on univariate (37 vs. 32 months; HR 1.20, 95% CI 0.87-1.64, p = .350) or multivariate (HR 0.99, 95% CI 0.71-1.38, p = .943) analysis.<br /><br /> NT followed by surgery was not associated with improved survival outcomes compared with SF among patients with localized AC. While NT is an acceptable alternative for patients with advanced disease, SF should remain the standard of care.<br /><br />NT followed by surgery was not associated with improved survival outcomes compared with SF among patients with localized AC.

We aimed to assess the consistency of eradication rates of concomitant and sequential therapies as for the first-line H.pylori eradication in Korea.<br /><br /> A nationwide multicenter retrospective study was conducted including 18 medical centers from January 2008 to December 2017. We included 3,800 adults who had test to confirm H.pylori eradication within 1year after concomitant or sequential therapy.<br /><br /> Concomitant and sequential therapy were prescribed for 2508 and 1292 patients, respectively. The overall eradication rate of concomitant therapy was significantly higher than that of sequential therapy (91.8% vs. 86.1%, p&lt;.001). In time trend analysis, the eradication rates of concomitant therapy were 90.2%, 88.2%, 92.1%, 94.3%, 91.1%, and 93.4% for each year from 2012 to 2017 with an increasing trend (p=.0146), while those of ST showed no significant trend (p=.0873). Among 263 patients with second-line therapy, bismuth quadruple therapy showed significantly higher eradication rate than quinolone-based triple therapy (73.9% vs. 51.5% in ITT analysis, p=.001; 82.7% vs. 63.0% in PP analysis, p=.002).<br /><br /> Concomitant therapy is the best regimen for the first-line H.pylori eradication showing consistently higher eradication rate with an increasing trend for the last 10years in Korea. Bismuth quadruple therapy should be considered for second-line therapy after eradication failure using non-bismuth quadruple therapy.<br /><br />Concomitant therapy is the best regimen for the first-line H. pylori eradication showing consistently higher eradication rate with an increasing trend for the last 10 years in Korea.

High-oleic soybean oils (HOSBO) are alternatives that provide functionality for different food applications. The objective of this study was to determine how consumption of diets containing HOSBO compared to other alternative oils, with similar functional properties, modifies LDL cholesterol (LDLc) and other risk factors and biomarkers of CHD. A triple-blind, crossover, randomized controlled trial was conducted in humans (n = 60) with four highly-controlled diets containing (1) HOSBO, (2) 8020 blend of HOSBO and fully hydrogenated soybean oil (HOSBO+FHSBO), (3) soybean oil (SBO), and (4) 5050 blend of palm oil and palm kernel oil (PO + PKO). Before and after 29 days of feeding, lipids/lipoproteins, blood pressure, body composition, and markers of inflammation, oxidation, and hemostasis were measured. LDLc, apolipoprotein B (apoB), NonHDL-cholesterol (HDLc), ratios of total cholesterol (TC)-to-HDLc and LDLc-to-HDL cholesterol, and LDL particle number and small LDL particles concentration were lower after HOSBO and HOSBO+FHSBO compared to PO (specific comparisons p  less then  0.05). Other than TCHDL, there were no differences in lipid/lipoprotein markers when comparing HOSBO+FHSBO with HOSBO. LDLc and apoB were higher after HOSBO compared to SBO (p  less then  0.05). PO + PKO increased HDLc (p  less then  0.001) and apolipoprotein AI (p  less then  0.03) compared to HOSBO and HOSBO+FHSBO. With the exception of lipid hydroperoxides, dietary treatments did not affect other CHD markers. HOSBO, and blends thereof, is a PHO replacement that results in more favorable lipid/lipoprotein profiles compared to PO + PKO (an alternative fat with similar functional properties).<br /><br /> Pathogens capable of impacting gastrointestinal tract tumor development are located in the oral cavity, but whether these oral bacteria are able to colonize the gastric mucosa in gastric cancer (GC) patients and whether Helicobacter pylori infection can influence this process remains to be established.<br /><br /> Microbial 16S rDNA deep sequencing was conducted to characterize bacteria present in paired gastric mucosa and tongue coating samples in 27 patients with superficial gastritis (SG) and 11 GC patients.<br /><br /> While the overall composition of the gastric mucosa and tongue coating microbiomes differed substantially, certain bacteria were present in both of these communities. The co-occurrence of bacteria between the tongue coating and gastric mucosa differed significantly between SG and GC patients. Of the 15 most abundant shared oral bacteria genera (the core shared oral bacteria), which were associated with differences in microbiota composition between these tongue coating and gastric mucosa, three were enriched in the gastric mucosa of GC patients relative to SG patients, whereas, 12 were depleted in GC patient samples. Furthermore, the prevalence and relative abundance of these core shared oral bacteria in the gastric mucosa were also linked to H.pylori infection status, and the core shared oral bacteria were also associated with the overall composition of the gastric mucosal microbiome.<br /><br /> Helicobacter pylori infections are linked to the co-occurrence of bacteria in the oral microbiome and the gastric mucosal microbiome. Ectopic colonization of oral microbes may be a primary driver of H.pylori-induced gastric microbial dysbiosis in patients with GC.<br /><br />Helicobacter pylori infections are linked to the co-occurrence of bacteria in the oral microbiome and the gastric mucosal microbiome.

They can possess unexpected optoelectronic properties and their radially oriented π-system makes them attractive for host-guest chemistry. Bending the π-subsystems can lead to chiral hoops. Herein, we report the stereoselective synthesis of two enantiomers of chiral conjugated nanohoops by incorporating dibenzo[a,e]pentalenes (DBPs), which are generated in the last synthetic step from enantiomerically pure diketone precursors. Owing to its bent shape, this diketone unit was used as the only bent precursor and novel "corner unit" in the synthesis of the hoops. The [6]DBP[4]Ph-hoops contain six antiaromatic DBP units and four bridging phenylene groups. The small HOMO-LUMO gap and ambipolar electrochemical character of the DBP units is reflected in the optoelectronic properties of the hoop. Electronic circular dichroism spectra and MD simulations showed that the chiral hoop did not racemize even when heated to 110 °C.
