Toxicol Res (Camb) 2024; 13:tfae155. [PMID: 39345794 PMCID: PMC11427753 DOI: 10.1093/toxres/tfae155] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Revised: 06/11/2024] [Accepted: 09/17/2024] [Indexed: 10/01/2024] Open
Abstract
The present study was performed to evaluate the therapeutic impact of Diospyros kaki fruit aqueous extract (DKFAE) on ethanol induced peptic ulcer. The phytochemical studies of DKFAE were investigated using colorometric analysis. Gastric ulcer was induced by one dose of ethanol (5 ml/Kg, b.w) on 24 h empty stomach. Then, the plant extract (200, 400 mg/kg) was orally administrated for 2 weeks. Famotidine (FAM: 40 mg/kg, b.w.): a reference drug was also tested. The effect of mixture dose between the fruit extract and FAM (DKFAE, 50 mg/kg PC, p.o. + FAM, 50 mg/kg PC, p.o.) was also evaluated. One hour after induction of ulcer blood samples were collected, stomach acidity and volume, as well as lesion counts were measured, then stomach and intestine of scarified rats were subjected to biochemical, macroscopic and microscopic studies. Results showed that DKFAE exhibited an important antioxidant potential. In vivo, the results showed that alcohol induced gastric damage, improving oxidative stress markers level such as MDA and H2O2, gastric and intestinal calcium and free iron. The intoxication by ethanol also produce an inflammation occurred by high level of the C-reactive protein (CRP) and alkaline phosphatase (ALP) activity in plasma. In contrast, DKFAE and the mixture dose significantly protect against macroscopic and histological injuries, the secretory profile disturbances, lipid peroxidation, antioxidant enzymes activities and non enzymatic antioxidant level decrease induced by ethanol administration. More impressively, the mixture dose exerted the more excellent effect than DKFAE and famotidine each alone showing is possible synergism.

Advanced interpenetrating polymer networks for innovative gastroretentive formulations targeting Helicobacter pylori gastric colonization. Eur J Pharm Sci 2024; 200:106840. [PMID: 38909691 DOI: 10.1016/j.ejps.2024.106840] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Revised: 04/25/2024] [Accepted: 06/20/2024] [Indexed: 06/25/2024]
Abstract
The escalating challenges of Helicobacter pylori-induced gastric complications, driven by rising antibiotic resistance and persistent cancer risks, underscore the demand for innovative therapeutic strategies. This study addresses this urgency through the development of tailored semi-interpenetrating polymer networks (semi-IPN) serving as gastroretentive matrices for amoxicillin (AMOX). They are biodegradable, absorb significant volume of simulated gastric fluid (swelling index > 360 %) and exhibit superporous microstructures, remarkable mucoadhesion, and buoyancy. The investigation includes assessment at pH 1.2 for comparative analysis with prior studies and, notably, at pH 5.0, reflecting the acidic environment in H. pylori-infected stomachs. The semi-IPN demonstrated gel-like structures, maintaining integrity throughout the 24-hour controlled release study, and disintegrating upon completing their intended function. Evaluated in gastroretentive drug delivery system performance, AMOX release at pH 1.2 and pH 5.0 over 24 h (10 %-100 %) employed experimental design methodology, elucidating dominant release mechanisms. Their mucoadhesive, buoyant, three-dimensional scaffold stability, and gastric biodegradability make them ideal for accommodating substantial AMOX quantities. Furthermore, exploring the inclusion of the potassium-competitive acid blocker (P-CAB) vonoprazan (VONO) in AMOX-loaded formulations shows promise for precise and effective drug delivery. This innovative approach has the potential to combat H. pylori infections, thereby preventing the gastric cancer induced by this pathogen.

The immunopathogenesis of Helicobacter pylori-induced gastric cancer: a narrative review. Front Microbiol 2024; 15:1395403. [PMID: 39035439 PMCID: PMC11258019 DOI: 10.3389/fmicb.2024.1395403] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2024] [Accepted: 05/06/2024] [Indexed: 07/23/2024] Open
Abstract
Helicobacter pylori infection is a well-established risk factor for the development of gastric cancer (GC). Understanding the immunopathogenesis underlying this association is crucial for developing effective preventive and therapeutic strategies. This narrative review comprehensively explores the immunopathogenesis of H. pylori-induced GC by delving into several key aspects, emphasizing the pivotal roles played by H. pylori virulence factors, including cytotoxin-associated gene A (cagA) and vacuolating cytotoxin A (vacA), blood group antigen-binding adhesin (babA), and sialic acid binding adhesin (sabA). Moreover, the review focuses on the role of toll-like receptors (TLRs) and cytokines in the complex interplay between chronic infection and gastric carcinogenesis. Finally, the study examines the association between H. pylori evasion of the innate and adaptive immune response and development of GC. A comprehensive understanding of the immunopathogenesis of H. pylori-induced GC is essential for designing targeted interventions to prevent and manage this disease. Further research is warranted to elucidate the intricate immune responses involved and identify potential therapeutic targets to improve patient outcomes.

BMC Public Health 2024; 24:1763. [PMID: 38956557 PMCID: PMC11221210 DOI: 10.1186/s12889-024-19104-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Accepted: 06/11/2024] [Indexed: 07/04/2024] Open
Abstract
OBJECTIVE To study the historical global incidence and mortality trends of gastric cancer and predicted mortality of gastric cancer by 2035. METHODS Incidence data were retrieved from the Cancer Incidence in Five Continents (CI5) volumes I-XI, and mortality data were obtained from the latest update of the World Health Organization (WHO) mortality database. We used join-point regression analysis to examine historical incidence and mortality trends and used the package NORDPRED in R to predict the number of deaths and mortality rates by 2035 by country and sex. RESULTS More than 1,089,000 new cases of gastric cancer and 769,000 related deaths were reported in 2020. The average annual percent change (AAPC) in the incidence of gastric cancer from 2003 to 2012 among the male population, South Korea, Japan, Malta, Canada, Cyprus, and Switzerland showed an increasing trend (P > 0.05); among the female population, Canada [AAPC, 1.2; (95%Cl, 0.5-2), P < 0.05] showed an increasing trend; and South Korea, Ecuador, Thailand, and Cyprus showed an increasing trend (P > 0.05). AAPC in the mortality of gastric cancer from 2006 to 2015 among the male population, Thailand [3.5 (95%cl, 1.6-5.4), P < 0.05] showed an increasing trend; Malta Island, New Zealand, Turkey, Switzerland, and Cyprus had an increasing trend (P > 0.05); among the male population aged 20-44, Thailand [AAPC, 3.4; (95%cl, 1.3-5.4), P < 0.05] showed an increasing trend; Norway, New Zealand, The Netherlands, Slovakia, France, Colombia, Lithuania, and the USA showed an increasing trend (P > 0.05). It is predicted that the mortality rate in Slovenia and France's female population will show an increasing trend by 2035. It is predicted that the absolute number of deaths in the Israeli male population and in Chile, France, and Canada female population will increase by 2035. CONCLUSION In the past decade, the incidence and mortality of gastric cancer have shown a decreasing trend; however, there are still some countries showing an increasing trend, especially among populations younger than 45 years. Although mortality in most countries is predicted to decline by 2035, the absolute number of deaths due to gastric cancer may further increase due to population growth.

Gastric carcinoma of the fundic gland type developed 32 years after Helicobacter pylori eradication for duodenal ulcer: a case report. Ann Med Surg (Lond) 2024; 86:4227-4230.

Abstract
Introduction Gastric cancer has been reported to occur with mild to moderate mucosal atrophy, particularly after the eradication of Helicobacter pylori (HP) more than 10 years previously. However, no conclusion has been reached on how many years of esophagogastroduodenoscopy should be performed after HP eradication. Presentation of case This was a case of gastric carcinoma of the fundic gland type (GCFGT) 32 years after the eradication of HP, which is the longest posteradication period reported. A 62-year-old male patient was diagnosed with GCFGT after HP eradication and regular esophagogastroduodenoscopy, which revealed a white raised lesion on the anterior wall of the upper part of the body. Endoscopic submucosal dissection was performed for GCFGT, and the vertical and horizontal margins were negative. Clinical discussion In this case, HP was eradicated in 1990, and GCFGT developed 32 years later. To the best of our knowledge, this is the longest case in which gastric cancer appeared after HP eradication. HP eradication therapy for a duodenal ulcer was first reported in 1990, supporting that this is the longest case. Conclusions This is the first case of gastric cancer more than 20 years after the eradication of HP. The endoscopic findings of this case are typical of GCFGT and may be useful when encountering such cases in the future. Therefore, the risk of gastric cancer should be considered for an extended period even after the eradication of HP, and regular esophagogastroduodenoscopy is recommended even after the eradication of HP.

Abstract
Helicobacter pylori is a prevalent bacterial pathogen globally, implicated in various gastrointestinal disorders. Current recommended antibiotic therapies for H. pylori infection have been proven to be therapeutically insufficient, with low eradication rates and high recurrence rates. Emerging evidence suggests that antibiotic therapy for H. pylori can lead to gastrointestinal and subsequent vaginal dysbiosis, posing challenges for conventional antibiotic approaches. Thus, this article proposes a novel probiotic therapy involving simultaneous oral and intra-vaginal probiotic administration alongside antibiotics for H. pylori treatment, aiming to enhance eradication rates and mitigate dysbiosis. We begin by providing an overview of gastrointestinal and vaginal microbiota and their interconnectedness through the vagina-gut axis. We then review the efficacy of current antibiotic regimens for H. pylori and discuss how antibiotic treatment impacts the vaginal microenvironment. To explore the feasibility of this approach, we evaluate the effectiveness of oral and intra-vaginal probiotics in restoring normal microbiota in the gastrointestinal and vaginal tracts, respectively. Additionally, we analyze the direct mechanisms by which oral and intra-vaginal probiotics act on their respective tracts and discuss potential cross-tract mechanisms. Considering the potential synergistic therapeutic effects of probiotics in both the gastrointestinal and vaginal tracts, dual-channel probiotic therapy holds promise as a more effective approach for H. pylori eradication and dysbiosis mitigation, presenting a novel concept in the collaborative treatment of gastrointestinal and genital disorders.

Abstract
BACKGROUND AND AIMS Population-based screening for gastric cancer (GC) in low prevalence nations is not recommended. The objective of this study was to develop a risk-prediction model to identify high-risk patients who could potentially benefit from targeted screening in a racial/ethnically diverse regional US population. METHODS We performed a retrospective cohort study from Kaiser Permanente Southern California from January 2008-June 2018 among individuals age ≥50 years. Patients with prior GC or follow-up <30 days were excluded. Censoring occurred at GC, death, age 85 years, disenrollment, end of 5-year follow-up, or study conclusion. Cross-validated LASSO regression models were developed to identify the strongest of 20 candidate predictors (clinical, demographic, and laboratory parameters). Records from 12 of the medical service areas were used for training/initial validation while records from a separate medical service area were used for testing. RESULTS 1,844,643 individuals formed the study cohort (1,555,392 training and validation, 289,251 testing). Mean age was 61.9 years with 53.3% female. GC incidence was 2.1 (95% CI 2.0-2.2) cases per 10,000 person-years (pyr). Higher incidence was seen with family history: 4.8/10,000 pyr, history of gastric ulcer: 5.3/10,000 pyr, H. pylori: 3.6/10,000 pyr and anemia: 5.3/10,000 pyr. The final model included age, gender, race/ethnicity, smoking, proton-pump inhibitor, family history of gastric cancer, history of gastric ulcer, H. pylori infection, and baseline hemoglobin. The means and standard deviations (SD) of c-index in validation and testing datasets were 0.75 (SD 0.03) and 0.76 (SD 0.02), respectively. CONCLUSIONS This prediction model may serve as an aid for pre-endoscopic assessment of GC risk for identification of a high-risk population that could benefit from targeted screening.

Abstract
In recent years, kaempferol, a natural flavonoid present in various fruits and vegetables, has received significant attention in gastrointestinal cancer research due to its varied therapeutic effects. Kaempferol has been proven to alter several molecular mechanisms and pathways, such as the PI3/Akt, mTOR, and Erk/MAPK pathway involved in cancer progression, showing its inhibitory effects on cell proliferation, survival, angiogenesis, metastasis, and migration. Kaempferol is processed in the liver and small intestine, but limited bioavailability has been a major concern in the clinical implications of kaempferol. Nano formulations have been proven to enhance kaempferol's efficacy in cancer prevention. The synergy of nanotechnology and kaempferol has shown promising results in in vitro studies, highlighting the importance for more in vivo research and clinical trials to determine safety and efficacy. This review aims to focus on the role of kaempferol in various types of gastrointestinal cancer and how the combination of kaempferol with nanotechnology helps in improving therapeutic efficacy in cancer treatment.

Abstract
Helicobacter pylori strains can be broadly classified into two groups based on whether they contain or lack a chromosomal region known as the cag pathogenicity island (cag PAI). Colonization of the human stomach with cag PAI-positive strains is associated with an increased risk of gastric cancer and peptic ulcer disease, compared to colonization with cag PAI-negative strains. The cag PAI encodes a secreted effector protein (CagA) and components of a type IV secretion system (Cag T4SS) that delivers CagA and non-protein substrates into host cells. Animal model experiments indicate that CagA and the Cag T4SS stimulate a gastric mucosal inflammatory response and contribute to the development of gastric cancer. In this review, we discuss recent studies defining structural and functional features of CagA and the Cag T4SS and mechanisms by which H. pylori strains containing the cag PAI promote the development of gastric cancer and peptic ulcer disease.

Abstract
Peptic ulcer disease (PUD) refers to acid-induced injury of the digestive tract, occurring mainly in the stomach (gastric ulcer (GU)) or duodenum (duodenal ulcer (DU)). In the present study, we conducted a large-scale, cross-ancestry meta-analysis of PUD combining genome-wide association studies with Japanese and European studies (52,032 cases and 905,344 controls), and discovered 25 new loci highly concordant across ancestries. An examination of GU and DU genetic architecture demonstrated that GUs shared the same risk loci as DUs, although with smaller genetic effect sizes and higher polygenicity than DUs, indicating higher heterogeneity of GUs. Helicobacter pylori (HP)-stratified analysis found an HP-related host genetic locus. Integrative analyses using bulk and single-cell transcriptome profiles highlighted the genetic factors of PUD being enriched in the highly expressed genes in stomach tissues, especially in somatostatin-producing D cells. Our results provide genetic evidence that gastrointestinal cell differentiations and hormone regulations are critical in PUD etiology.

Abstract
OBJECTIVE Previous studies have indicated that neurotransmitters play important roles in the occurrence and development of gastric cancer. MAOA is an important catecholamine neurotransmitter-degrading enzyme involved in the degradation of norepinephrine, epinephrine and serotonin. To find a potential therapeutic target for the treatment of gastric cancer, the biological functions of MAOA and the underlying mechanism in gastric cancer need to be explored. METHODS The Cancer Genome Atlas (TCGA), Gene Expression Omnibus (GEO) datasets, Kaplan‒Meier (KM) plotter were used to identify the differentially expressed genes, which mainly involved the degradation and synthesis enzymes of neurotransmitters in gastric cancer. We also investigated the expression pattern of MAOA in human and mouse tissues and cell lines by immunohistochemistry and Western blotting analysis. Western blotting, quantitative real-time PCR, enzyme-linked immunosorbent assay (ELISA) and a Seahorse experiment were used to identify the molecular mechanism of cancer cell glycolysis. MAOA expression and patient survival were analysed in the Ren Ji cohort, and univariate and multivariate analyses were performed based on the clinicopathological characteristics of the above samples. RESULTS MAOA expression was significantly downregulated in gastric cancer tissue and associated with poor patient prognosis. Moreover, the expression level of MAOA in gastric cancer tissue had a close negative correlation with the SUXmax value of PET-CT in patients. MAOA suppressed tumour growth and glycolysis and promoted cancer cell apoptosis. We also reported that MAOA can interact with NDRG1 and regulate glycolysis through suppression of the PI3K/Akt/mTOR pathway. MAOA expression may serve as an independent prognostic factor in gastric cancer patients. CONCLUSIONS MAOA attenuated glycolysis and inhibited the progression of gastric cancer through the PI3K/Akt/mTOR pathway. Loss of function or downregulation of MAOA can facilitate gastric cancer progression. Overexpression of MAOA and inhibition of the PI3K/Akt/mTOR pathway may provide a potential method for gastric cancer treatment in clinical therapeutic regimens.

Abstract
Chronic inflammation is linked to carcinogenesis, particularly in the digestive organs, i.e., the stomach, colon, and liver. The mechanism of this effect has, however, only partly been focused on. In this review, we focus on different forms of chronic hepatitis, chronic inflammatory bowel disease, and chronic gastritis, conditions predisposing individuals to the development of malignancy. Chronic inflammation may cause malignancy because (1) the cause of the chronic inflammation is itself genotoxic, (2) substances released from the inflammatory cells may be genotoxic, (3) the cell death induced by the inflammation induces a compensatory increase in proliferation with an inherent risk of mutation, (4) changes in cell composition due to inflammation may modify function, resulting in hormonal disturbances affecting cellular proliferation. The present review focuses on chronic gastritis (Helicobacter pylori or autoimmune type) since all four mechanisms may be relevant to this condition. Genotoxicity due to the hepatitis B virus is an important factor in hepatocellular cancer and viral infection can similarly be central in the etiology and malignancy of inflammatory bowel diseases. Helicobacter pylori (H. pylori) is the dominating cause of chronic gastritis and has not been shown to be genotoxic, so its carcinogenic effect is most probably due to the induction of atrophic oxyntic gastritis leading to hypergastrinemia.

Abstract
Most cases of gastric cancer are caused by chronic Helicobacter pylori infection, but the lack of early onco-diagnostics and a high risk for antibiotic resistance hampers early intervention through eradication of H. pylori infection by antibiotics. We reported on a protective mechanism where H. pylori gastric mucosal attachment can be reduced by natural antibodies that block the binding of its attachment protein BabA. Here we show that challenge infection with H. pylori induced response of such blocking antibodies in both human volunteers and in rhesus macaques, that mucosal vaccination with BabA protein antigen induced blocking antibodies in rhesus macaques, and that vaccination in a mouse model induced blocking antibodies that reduced gastric mucosal inflammation, preserved the gastric juice acidity, and fully protected the mice from gastric cancer caused by H. pylori.

Abstract
BACKGROUND Effective risk prediction models are lacking for personalized endoscopic screening of gastric cancer (GC). We aimed to develop, validate, and evaluate a questionnaire-based GC risk assessment tool for risk prediction and stratification in the Chinese population. METHODS In this three-stage multicenter study, we first selected eligible variables by Cox regression models and constructed a GC risk score (GCRS) based on regression coefficients in 416,343 subjects (aged 40-75 years) from the China Kadoorie Biobank (CKB, development cohort). In the same age range, we validated the GCRS effectiveness in 13,982 subjects from another independent Changzhou cohort (validation cohort) as well as in 5348 subjects from an endoscopy screening program in Yangzhou. Finally, we categorized participants into low (bottom 20%), intermediate (20-80%), and high risk (top 20%) groups by the GCRS distribution in the development cohort. RESULTS The GCRS using 11 questionnaire-based variables demonstrated a Harrell's C-index of 0.754 (95% CI, 0.745-0.762) and 0.736 (95% CI, 0.710-0.761) in the two cohorts, respectively. In the validation cohort, the 10-year risk was 0.34%, 1.05%, and 4.32% for individuals with a low (≤ 13.6), intermediate (13.7~30.6), and high (≥ 30.7) GCRS, respectively. In the endoscopic screening program, the detection rate of GC varied from 0.00% in low-GCRS individuals, 0.27% with intermediate GCRS, to 2.59% with high GCRS. A proportion of 81.6% of all GC cases was identified from the high-GCRS group, which represented 28.9% of all the screened participants. CONCLUSIONS The GCRS can be an effective risk assessment tool for tailored endoscopic screening of GC in China. Risk Evaluation for Stomach Cancer by Yourself (RESCUE), an online tool was developed to aid the use of GCRS.

Abstract
Red-to-near-infrared (NIR) fluorescent probes, with advantages such as high spatiotemporal resolution and in situ sensing abilities, are highly attractive for diagnosis of gastrointestinal diseases and targeted drug development. However, conventional red-to-NIR fluorophores with electron closed-shell structures require tedious synthetic procedures for preparation, and it is difficult to further decorate them with sensing groups. In this study, a series of easily prepared pyrroles with simple structures that can quickly be transformed into red-to-NIR emissive radical cations in acidic buffer solution and in vivo stomachs is developed. The in-situ-generated red-to-NIR emissive pyrrole radical cations in the stomach have excellent biocompatibility and stability and can be used not only for intravital gastrointestinal imaging with high spatiotemporal resolution, but also for dynamic monitoring of the gastric emptying process and assessment of anti-gastric-acid therapy. The acidity-induced generation of pyrrole radical cations is believed to provide a facile strategy for developing red-to-NIR fluorophores and studying gastrointestinal diseases.

Abstract
Stephan Schätzl was the parish priest of Viechtwang, Upper Austria. He lived in the aftermath of the Peace of Augsburg in a period of schism between Roman Catholics and Lutherans. His portrait, depicted only 6 days before his demise in 1590, shows that he had extreme ante mortem cachexia. Documentary sources detailed his life and ill-health and it is proposed that he had chronic gastro-duodenal ulcerative disease which ultimately led his to death.

Abstract
BACKGROUND Helicobacter pylori is an infection of concern for its chronic colonization leading to peptic ulcers and gastric cancer. In recent times, microRNAs have been extensively studied to understand their role in the pathogenesis of this bacteria in diverse contexts of gastric diseases. The current analysis reports the microRNA-mRNA interactions that are associated with effective survival and virulence of this pathogen. MATERIALS AND METHODS We convened differentially regulated human microRNAs responsive to H. pylori infection (HP-hDEmiRs) at different multiplicity of infection and time points in human gastric cell lines through retrospective data mining of experimental studies. In view of the molecular disparity of clinical samples and animal models, data from tissue, serum/plasma, urine, and ascites were excluded. Further, we utilized diverse bioinformatics approaches to retrieve experimentally validated, high-confidence targets of the HP-hDEmiRs to analyze the microRNA-mRNA interactions that are relevant to H. pylori pathogenesis. RESULTS A total of 39 HP-hDEmiRs that showed unidirectional expression of either overexpression or downregulation were identified to modulate 23 targets explicitly studied under this infection. We also identified 476 experimentally validated targets regulated by at least 4 of the HP-hDEmiRs. In addition to the pathways prior-associated with H. pylori infection, the microRNA-mRNA interactome analysis identified several cellular processes and pathways highly associated with cell cycle, cell division, migration, and carcinogenesis. CONCLUSION This study generated a platform to study the mechanisms utilized by this pathogen using microRNAs as surrogate.

Abstract
BACKGROUND The mainstay of surgical management of perforated peptic ulcer is omental patch repair. Advances in minimally invasive techniques have shown feasibility of laparoscopic omental patch repair (LOPR). Laparoscopic omental patch repair is limited by learning curve (LC), but there is a lack of reporting of LC in LOPR. This study aims to compare outcomes following LOPR versus open omental patch repair (OOPR) with reporting of LC. METHODS PubMed, Embase, The Cochrane Library, and Scopus were systematically searched from inception till January 2022 for randomized controlled trials (RCTs) and non-RCTs comparing LOPR and OOPR in perforated peptic ulcer. Exclusion criteria were primary repair without use of omental patch repair. Primary outcomes were 30-day mortality, postoperative leak, and LC analysis. RESULTS There were a total of 29 studies including 5,311 patients (LOPR, n = 1,687; OOPR, n = 3,624), with 4 RCTs with 238 patients (LOPR, n = 118; OOPR, n = 120). Majority of ulcers were located in the duodenum (57.0%) followed by stomach (30.7%). Mean ulcer size ranged from 5 to 16.2 mm in LOPR and 4.7 to 15.8 mm in OOPR. Laparoscopic omental patch repair was associated with lower 30-day mortality (odds ratio [OR], 0.57; 95% confidence interval [CI], 0.35-0.92; p = 0.02), overall morbidity (OR, 0.31; 95% CI, 0.18-0.53; p < 0.0001), surgical site infection (OR, 0.27; 95% CI, 0.18-0.42; p < 0.00001), and length of stay (mean difference, -2.84 days; 95% CI, -3.63 to -2.06; p < 0.00001). Postoperative leakage (OR, 1.06; 95% CI, 0.43-2.61; p = 0.90) was comparable between LOPR and OOPR. Only three studies analyzed the proportion of consultants to trainees; LOPR was performed mainly by consultants (range, 82.4-91.4%), while OOPR was mainly performed by trainees (range, 52.8-96.8%). One study showed that consultants who performed open conversion had shorter operating time compared with chief residents (85 vs. 186.6 minutes, p < 0.003). CONCLUSION Laparoscopic omental patch repair has lower mortality, overall morbidity, length of stay, intraoperative blood loss, and postoperative pain compared with OOPR. More prospective studies should be conducted to evaluate LC in LOPR. LEVEL OF EVIDENCE Systematic Review and Meta-Analysis; Level IV.

Freshwater Clam Extract Attenuates Indomethacin-Induced Gastric Damage In Vitro and In Vivo. Foods 2022; 12:foods12010156.

Abstract
Contemporary pharmacological studies have reported that freshwater clam (Corbicula fluminea) can provide a broad spectrum of bioactivities, including antioxidant, anticancer, antihypertensive, hepatoprotective, and hypocholesterolemic effects. The aim of this study was to evaluate the gastroprotective effects of water extract of freshwater clam (WEC) on indomethacin (IND)-induced gastric mucosal cell damage in vitro and gastric ulcer in vivo. The cell viability of rat gastric mucosa RGM-1 cells was markedly decreased by 0.8 mM of IND treatment, and pre-treated with various concentration of WEC significantly restored IND-induced cell damage in a dose-dependent manner. WEC also significantly attenuated the elevated reactive oxygen species (ROS) levels, inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression, and nuclear factor-κB (NF-κB) p65 nuclear translocation induced by IND. In the in vivo study, IND caused severe gastric ulcer in Wistar rats, while WEC pretreatment effectively reduced the ulcer area and edema in the submucosa. We found that WEC significantly restored glutathione (GSH) content in gastric mucosa in a dose-dependent manner (p < 0.05). The reduction of prostaglandin E2 (PGE2) caused by IND was also improved with higher doses of WEC administration. Moreover, the overexpression of COX-2, iNOS, and tumor necrosis factor-α (TNF-α) proteins in gastric mucosa was downregulated by administration of WEC. Consequently, WEC can be used as a potential nutritional supplement to improve NSAIDs-caused gastric mucosal lesions.

Abstract
The stomach is a hostile environment for most microbes because strong gastric acid kills indigenous microorganisms. Thus, the mass of indigenous microbes detected by traditional culturing method in a highly acidic stomach is reported to be very small. However, in a stomach with less acidity due to atrophic changes of the gastric mucosa, the number of live gastric microbiota dramatically increases and their composition changes. A probiotic is defined as a live microorganism that, when administered in adequate amounts, confers a health benefit on the host. The administration of probiotics to the stomach has thus far been considered impractical, mainly due to the strong acidity in the stomach. The identification of candidate probiotic strains with sufficient resistance to acidity and the ability to achieve close proximity to the gastric mucosa could enable the application of probiotics to the stomach. The utilization of probiotics alone for Helicobacter pylori (H. pylori) infection significantly improves gastric mucosal inflammation and decreases the density of H. pylori on the mucosa, although complete eradication of H. pylori has not yet been demonstrated. The use of probiotics in combination with antimicrobial agents significantly increases the H. pylori eradication rate, especially when the H. pylori strains are resistant to antimicrobial agents. While H. pylori has been considered the most important pathogenic bacterium for the development of gastric cancer, bacteria other than H. pylori are also suggested to be causative pathogens that promote the development of gastric cancer, even after the eradication of H. pylori. Increased non-H. pylori Gram-negative bacteria in the stomach with weak acidity accompanying atrophic gastritis may perpetuate gastric mucosal inflammation and accelerate carcinogenic progression, even after H. pylori eradication. Probiotics restore the acidity in this stomach environment and may therefore prevent the development of gastric cancer by termination of Gram-negative bacteria-induced inflammation. Functional dyspepsia (FD) is defined as the presence of symptoms that are thought to originate in the gastroduodenal region in the absence of any organic, systematic or metabolic diseases. Accumulating evidence has pointed out the duodenum as a target region underlying the pathophysiology of FD. A randomized placebo-controlled clinical trial using a probiotic strain (LG21) demonstrated a significant improving effect on major FD symptoms. One of the possible mechanisms of this effect is protection of the duodenal mucosa from injurious intestinal bacteria through the resolution of small intestinal bacterial over growth.

Abstract
Gastric cancer (GC) is one of the major causes of cancer deaths worldwide. The disease is seldomly detected early and this limits treatment options. Because of its heterogeneous and complex nature, the disease remains poorly understood. The literature supports the contribution of the gut microbiome in the carcinogenesis and chemoresistance of GC. Drug resistance is the major challenge in GC therapy, occurring as a result of rewired metabolism. Metabolic rewiring stems from recurring genetic and epigenetic factors affecting cell development. The gut microbiome consists of pathogens such as H. pylori, which can foster both epigenetic alterations and mutagenesis on the host genome. Most of the bacteria implicated in GC development are Gram-negative, which makes it challenging to eradicate the disease. Gram-negative bacterium co-infections with viruses such as EBV are known as risk factors for GC. In this review, we discuss the role of microbiome-induced GC carcinogenesis. The disease risk factors associated with the presence of microorganisms and microbial dysbiosis are also discussed. In doing so, we aim to emphasize the critical role of the microbiome on cancer pathological phenotypes, and how microbiomics could serve as a potential breakthrough in determining effective GC therapeutic targets. Additionally, consideration of microbial dysbiosis in the GC classification system might aid in diagnosis and treatment decision-making, taking the specific pathogen/s involved into account.

Abstract
Simple Summary Gastric cancer (GC) is the fifth most common type of cancer and the fourth most common cause of cancer-related mortality. In this meta-analysis, we utilized SToP consortium data to investigate the association between gastric ulcer (GU) and duodenal ulcer (DU) and development of GC. Among 4106 GC cases and 6922 controls, we detected a positive association between GU and GC (OR = 3.04, 95% CI: 2.07–4.49). On the other hand, no significant association between DU and GC was detected (OR = 1.03, 95% CI: 0.77–1.39). In the pooled analysis, incorporating 11 case–control studies revealed positive association between the gastric ulcer and risk of gastric cancer. Abstract Background. Gastric cancer (GC) is the fifth most common type of cancer and the fourth most common cause of cancer-related mortality. Although the risk of GC and peptic ulcer disease (PUD) is known to be increased by H. pylori infection, evidence regarding the direct relationship between PUD and GC across ethnicities is inconclusive. Therefore, we investigated the association between PUD and GC in the Stomach cancer Pooling (StoP) consortium. Methods. History of peptic ulcer disease was collected using a structured questionnaire in 11 studies in the StoP consortium, including 4106 GC cases and 6922 controls. The two-stage individual-participant data meta-analysis approach was adopted to generate a priori. Unconditional logistic regression and Firth’s penalized maximum likelihood estimator were used to calculate study-specific odds ratios (ORs) and 95% confidence intervals (CIs) for the association between gastric ulcer (GU)/duodenal ulcer (DU) and risk of GC. Results. History of GU and DU was thoroughly reported and used in association analysis, respectively, by 487 cases (12.5%) and 276 controls (4.1%), and 253 cases (7.8%) and 318 controls (6.0%). We found that GU was associated with an increased risk of GC (OR = 3.04, 95% CI: 2.07–4.49). No association between DU and GC risk was observed (OR = 1.03, 95% CI: 0.77–1.39). Conclusions. In the pooled analysis of 11 case–control studies in a large consortium (i.e., the Stomach cancer Pooling (StoP) consortium), we found a positive association between GU and risk of GC and no association between DU and GC risk.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:9986. [PMID: 36011621 PMCID: PMC9408128 DOI: 10.3390/ijerph19169986] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/09/2022] [Revised: 08/09/2022] [Accepted: 08/10/2022] [Indexed: 06/15/2023]
Abstract
Objective The aim of this study was to investigate the cost-effectiveness of Helicobacter pylori (H. pylori) screening and eradication treatment in an asymptomatic population in China and to explore the most cost-effective screening protocol for H. pylori. Method We used TreeAge 2019 to construct Markov models to assess the direct healthcare costs and quality-adjusted life years (QALYs) and the cost per year of life saved (YoLS) of three therapies, i.e., annual, triennial and five-yearly H. pylori screening. Excess probabilities were derived from published high quality studies and Meta-analyses, and costs and utilities were derived from the Chinese Yearbook of Health Care Statistics and published studies. Incremental cost-effectiveness ratios (ICERs) were used to describe the results. The willingness-to-pay threshold was set at China's Gross National Product per capita. Result In the asymptomatic population, the ICER per QALYs gained was US$1238.47 and US$1163.71 for every three and five years of screening compared to the annual screening group; the ICER per YoLS gained was US$3067.91 and US$1602.78, respectively. Conclusion Screening for H. pylori in asymptomatic populations in China and eradicating treatment for those who test positive is cost-effective. Increasing screening participation in asymptomatic populations is more effective than increasing the frequency of screening. From a national payer perspective, it is cost-effective to screen the general asymptomatic population in China for H. pylori and to eradicate those who test positive. Individuals need to choose a screening programme that they can afford according to their financial situation.

[PMID: 36011484 PMCID: PMC9408698 DOI: 10.3390/ijerph19169852] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Revised: 08/07/2022] [Accepted: 08/08/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Cancer is considered a major public health problem due to its increasing incidence and high mortality. This study aims to identify risk factors for cancer mortality in Spain. METHODS Retrospective population-based cohort study in 20,397 participants of the 2011/2012 National Health Survey in Spain. Risk factors associated with mortality due to neoplasm from 2011 to 2017 were analyzed, and hazard ratios were calculated with a multivariate Cox model with competing risks for mortality from other causes. RESULTS Myocardial infarction, chronic obstructive pulmonary disease, cirrhosis, and mental disorders were associated with an increased risk of mortality due to neoplasm. Male sex, age over 50 years, history or current smoking habit, negligible intake of legumes, and poorer self-perceived health were also associated with increased cancer mortality. CONCLUSIONS Comorbidities, tobacco use, poor diet, and worse self-perceived health were the main risk factors for cancer mortality in Spain.

Helicobacter bilis infection induces oxidative stress in and enhances the proliferation of human cholangiocytes. Helicobacter 2022; 27:e12908. [PMID: 35661483 DOI: 10.1111/hel.12908] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2021] [Revised: 05/02/2022] [Accepted: 05/17/2022] [Indexed: 12/26/2022]
Abstract
BACKGROUND Helicobacter bilis, an enterohepatic Helicobacter species, represents a carcinogenic risk factor for cholangiocytes owing to the prevalence of infections in patients with biliary tract cancer, cholecystitis, and pancreaticobiliary maljunction. However, the effect of H. bilis infection on cholangiocytes and the process and mechanism of carcinogenesis are not known. We aimed to determine the effects of H. bilis on cholangiocytes, focusing on inflammation and oxidative stress. MATERIALS AND METHODS Helicobacter bilis and MMNK-1 cells were cocultured for 24 h and inflammatory cytokine secretion was evaluated. Furthermore, MMNK-1 cell proliferation, intracellular reactive oxidant species (ROS) production, and DNA damage caused by ROS were investigated. All factors were compared with and without H. bilis infection. RESULTS Interleukin (IL)-6 and IL-8 secretion were significantly increased in MMNK-1 cocultures with H. bilis (IL-6, 24.3 ± 12.2 vs. 271.1 ± 286.4 pg/ml; IL-8, 167.6 ± 78.7 vs. 1085.1 ± 1047.1 pg/ml, p < .05). MMNK-1 proliferation was also significantly higher in H. bilis cocultures (1.05 ± 0.02 vs. 1.00-fold, respectively; p < .05). Coculturing enhanced the production of ROS in MMNK-1 cells depending on the cell concentration of H. bilis (1.0 vs. 1.17 ± 0.06, p < .05); however, DNA injury was not observed in cocultures with H. bilis (5.35 ± 0.87 vs. 6.08 ± 0.55 pg/μl, p = .06). CONCLUSIONS Helicobacter bilis infection induced ROS production in and enhanced the proliferation of cholangiocytes.

Life (Basel) 2022; 12:life12081106. [PMID: 35892908 PMCID: PMC9330504 DOI: 10.3390/life12081106] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2022] [Revised: 07/16/2022] [Accepted: 07/20/2022] [Indexed: 12/02/2022] Open
Abstract
Nowadays, an increased interest in natural compounds with preventive or therapeutic potential for various diseases has been observed. Given the involvement of oxidative stress in the pathogenesis of gastric ulcer (GU) and the wide range of bioactive compounds isolated from snails, this study aimed to investigate the protective effect of Cornu aspersum (Müller, 1774) mucus on ethanol-induced GUs. Male albino mice were divided into Control, Ethanol, Mucus + Ethanol and Mucus + Omeprazole treated groups. The GUs were induced by administration of 96% ethanol (10 mL/kg, per os). One hour before ulcer induction, the mice of Mucus + Ethanol group were pretreated with mucus (20 mg/kg, per os), and the mice of Mucus + Omeprazole group were pretreated with omeprazole (20 mg/kg, per os). Ethanol administration caused grave lesions of gastric mucosa and a significant decrease of glutathione (GSH) and superoxide dismutase (SOD), catalase, and glutathione reductase (GR) activities. In the animals with mucus or omeprazole pre-administration compared to the Ethanol group, the following were observed: only a small number of hemorrhagic fields, significantly reduced GU index with calculated 73% protection by mucus and 78% protection by omeprazole, and significant recovery of mucosal GSH and SOD and GR activities. In addition, the mucus inhibited Helicobacter pylori growth. Thus, the protective effect of C. aspersum mucus on both gastric mucosa and gastric antioxidant potential in ethanol-induced GU model suggests that it may serve as a good tool for prevention of this disease.

Abstract
BACKGROUND Peptic ulcer disease (PUD) and gastric cancer (GC) are more prevalent in individuals with low socioeconomic status (SES) and share several risk factors. The aim of this study was to investigate the mediating role of PUD in the association between established risk factors and GC. METHODS We conducted a pooled analysis of 12 studies from the Stomach Cancer Pooling Project Consortium, including a total of 4877 GC cases and 11 808 controls. We explored the mediating role of PUD in the association between SES, tobacco smoking, heavy alcohol drinking and salt intake, and GC. Also, we assessed the ORs and 95% CIs of the risk factors and both PUD and GC. RESULTS PUD mediated 36% of the smoking effect mainly among men. Other risk factors were only slightly mediated by PUD (SES, 5.3%; heavy alcohol drinking, 3.3%; and salt intake, 2.5%). No significant difference was found when excluding PUD diagnosed within 2 years from GC. CONCLUSIONS Our study provides innovative information on the mechanism of stomach mucosal damage leading to PUD and GC, with respect to the effect of tobacco smoking in particular.

Scope and Limitations of Current Antibiotic Therapies against Helicobacter pylori: Reviewing Amoxicillin Gastroretentive Formulations. Pharmaceutics 2022; 14:pharmaceutics14071340.

Abstract
Even though general improvement of quality of life has happened around the globe, statistics show that gastric cancer is still a very serious medical concern in some regions of the world. A big portion of malignant neoplasms that develop inside the stomach are linked to an infection of Helicobacter pylori; in fact, this pathogen has already been categorized as a group 1 carcinogen by the World Health Organization (WHO). Still, the efficacy of current anti-H. pylori therapeutic approaches is insufficient and follows a worrying decreasing trend, mainly due to an exponential increase in resistance to key antibiotics. This work analyzes the clinical and biological characteristics of this pathogen, especially its link to gastric cancer, and provides a comprehensive review of current formulation trends for H. pylori eradication. Research effort has focused both on the discovery of new combinations of chemicals that function as optimized antibiotic regimens, and on the preparation of gastroretentive drug delivery systems (GRDDSs) to improve overall pharmacokinetics. Regarding the last topic, this review aims to summarize the latest trend in amoxicillin-loaded GRDDS, since this is the antibiotic that has shown the least bacterial resistance worldwide. It is expected that the current work could provide some insight into the importance of innovative options to combat this microorganism. Therefore, this review can inspire new research strategies in the development of efficient formulations for the treatment of this infection and the consequent prevention of gastric cancer.

Abstract
BACKGROUND Helicobacter pylori infection is the leading cause of peptic ulcer and chronic gastritis and may initiate gastric carcinogenesis following the Correa cascade. Another lineage of metaplasia, spasmolytic peptide-expressing metaplasia (SPEM) has recently been found to be an alternative precursor to gastric cancer. To date, few reports have investigated gastric precancerous lesions among children with H. pylori infection. This study aimed to evaluate the histopathological pattern of H. pylori atrophic gastritis in children and the extent of precancerous lesions. MATERIALS AND METHODS This study enrolled pediatric patients with H. pylori infection from 1998 to 2019. During esophagogastroduodenoscopy examinations, biopsy fragments were collected from the gastric antrum and corpus for rapid urease test, culture, and histology evaluation. The presence and degree of chronic inflammation, activity of gastritis, H. pylori density, atrophy, and intestinal metaplasia (IM) were assessed according to the modified Updated Sydney System. Trefoil factor 2 (TFF2) immunohistochemistry was also performed to assess SPEM in the gastric tissues collected from each case using rabbit anti-human TFF2 antibodies. RESULTS A total of 92 children with H. pylori infection and adequate gastric mucosa biopsies were enrolled. Esophagogastroduodenoscopy showed that 39 (42.4%) had duodenal ulcers, 11 (12.0%) had gastric ulcers, 41 (44.6%) had gastritis, and 1 (1.1%) had negative findings. Mild-to-moderate IM was identified in 4 patients (4.3%). SPEM was found in 8 patients (8.7%) with a significantly higher incidence among female patients (15.8% vs. 8.7%, p = .031). Gastric glandular atrophy presented in 28 patients (30.4%), and high-grade atrophy was more common in female patients (3.2% vs. 1.9%, p = .031). CONCLUSIONS The prevalence rates of atrophic gastritis in the children with H. pylori infection were 30.4% for gastric glandular atrophy, 4.3% for IM and 8.7% for SPEM. SPEM and high-grade atrophy were more common in female patients.

Abstract
GOAL The aim of this study was to evaluate current practice in gastric ulcer follow-up to establish diagnostic yield and predictors of malignancy. BACKGROUND Repeat gastroscopy is routinely performed to confirm gastric ulcer healing and exclude malignancy. However, the incidence of malignancy at follow-up endoscopy is low, without consensus regarding case selection and timing. STUDY New gastric ulcers diagnosed on gastroscopy at 2 institutions in Australia were identified through keyword search of endoscopy reports over a 5-year period (2013 to 2017). Data collected included patient demographics, clinical presentation, and endoscopic and histologic findings from initial and subsequent gastroscopies. RESULTS Of 795 patients, repeat gastroscopy was performed in 440 (55%). Malignancy was diagnosed in 52 (7%) with 83% identified at initial gastroscopy. Eight cancers were identified at repeat gastroscopy with malignancy yield of 2% (8/440). Three were diagnosed in patients with benign initial ulcer histology (3/286, 1%). One cancer was diagnosed during follow-up in a patient with benign histology but no repeat gastroscopy (1/286, 0.3%). Predictors of benign ulcers were absence of endoscopic suspicion [odds ratio (OR) 0.1 (0.03-0.13), P≤0.005], complete healing on repeat gastroscopy [OR 0.5 (0.34-0.70), P=0.036] and benign initial histology [OR 0.12 (0.43-0.90), P≤0.005]. CONCLUSIONS Seven percent of new gastric ulcers were malignant with most identified with biopsy on initial gastroscopy. Malignancy yield from follow-up gastroscopy was 2%. Diagnostic yield of endoscopic follow-up may be low in ulcers with benign appearance and adequate histology. However, current practice of repeat gastroscopy is warranted in the absence of patient-based and lesion-based predictors of malignancy.

Abstract
Cumulative evidence shows that fibrogenic stroma and stiff extracellular matrix (ECM) not only result from tumor growth but also play pivotal roles in cellular transformation and tumor initiation. This emerging concept may largely account for the increased cancer risk associated with environmental fibrogenic agents, such as asbestos and silica, and with chronic conditions that are fibrogenic, such as obesity and diabetes. It may also contribute to poor outcomes in patients treated with certain chemotherapeutics that can promote fibrosis, such as bleomycin and methotrexate. Although the mechanistic details of this phenomenon are still being unraveled, we provide an overview of the experimental evidence linking fibrogenic stroma and tumor initiation. In this Review, we will summarize the causes and consequences of fibrous stroma and how this stromal cue is transmitted to the nuclei of parenchymal cells through a physical continuum from the ECM to chromatin, as well as ECM-dependent biochemical signaling that contributes to cellular transformation.

Abstract
Gastric cancer presents with similar clinical symptoms as gastric ulcer, and the morphologic features of gastroscopy overlap considerably. We report a 58-year-old man with the clinical presentation of recurrent gastric discomfort and black stools. A suspected malignant tumor of the gastric antrum-pylorus was observed on gastroscopy. Contrast-enhanced CT showed enhancement of the lesion. PET/CT revealed an FDG-avid lesion at the gastric antrum-pylorus, an intense FDG-uptake perigastric lymph node, and an enlarged nodule with high FDG uptake in the right abdominal wall. Subsequent surgical pathology revealed an inflammatory ulcer of the gastric antrum-pylorus with reactive hyperplastic lymph node, while the lesion in the right abdominal wall was a scar nodule. This case suggests that when multiple FDG-avid lesions accompany an atypical gastric ulcer, it can easily lead to misdiagnosis, and therefore more emphasis should be placed on histopathological analysis.

Wang YL, Chan XW, Chan KS, Shelat VG. Omental patch repair of large perforated peptic ulcers ≥25 mm is associated with higher leak rate. J Clin Transl Res 2021; 7:759-766. [PMID: 34988327 PMCID: PMC8710357] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 11/02/2021] [Accepted: 11/07/2021] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND AND AIM Omental patch repair is the present gold-standard technique for patients with perforated peptic ulcers (PPUs). Data are lacking regarding the safe ulcer size for omental patch repair leak (OPL). We analyze our experience in managing PPU to identify an ulcer size cut-off for predicting OPL. METHODS Patients who had undergone omental patch repair for PPU between Jan 2004 and Apr 2016 were included. Demographic data, the American Society of Anesthesiologists score, ulcer size, operative approach, post-operative complications, and length of stay were recorded. OPL, intra-abdominal collection, repeat surgery, and 30-day mortality were recorded. The relationship between ulcer size, pre-operative characteristics, and OPL were investigated with univariate and multivariate logistic regression. Receiver operating characteristic curve analysis derived the ulcer size cut-off to predict OPL. In addition, we analyzed if ulcer size predicted mortality or malignancy. RESULTS Six hundred and ninety patients with a mean age of 55.1 years (range 16-94) were managed for PPU during the study period. Free air on X-ray was evident in 417 (60.4%) patients. Mean ulcer size was 7.8 mm (range 1-50). OPL occurred in 15 patients (2.2%) and 30-day mortality was 7.4% (n=51). Multivariate analysis found ulcer size increase of 10 mm (OR 3.30, 95% CI 1.81-6.02, P<0.001) predicted increased risk of OPL. At 25 mm cut-off, sensitivity was 26.7%, specificity was 97.2%, positive likelihood ratio was 9.47, and negative likelihood ratio was 0.76 for OPL. CONCLUSION Ulcer size increase in 10 mm increases leak rate by 3.3 times. Ulcer size ≥25 mm predicts OPL. RELEVANCE FOR PATIENTS Increased risk of OPL for ≥25 mm warrants need for close post-operative monitoring and lowers threshold for investigations in event of clinical deterioration. Decision for omental patch repair versus gastrectomy however should not be based on ulcer size alone.

Advances in the Aetiology & Endoscopic Detection and Management of Early Gastric Cancer. Cancers (Basel) 2021; 13:cancers13246242.

Abstract
Simple Summary Gastric adenocarcinoma has remained a highly lethal disease. Awareness and recognition of preneoplastic conditions (including gastric atrophy and intestinal metaplasia) using high-resolution white-light endoscopy as well as chromoendoscopy is therefore essential. Helicobacter pylori, a class I carcinogen, remains the main contributor to the development of sporadic distal gastric neoplasia. Management of early gastric neoplasia with endoscopic resections should be in line with standard indications. A multidisciplinary approach to any case of an early gastric neoplasia is imperative. Hereditary forms of gastric cancer require a tailored approach and individua-lized surveillance. Abstract The mortality rates of gastric carcinoma remain high, despite the progress in research and development in disease mechanisms and treatment. Therefore, recognition of gastric precancerous lesions and early neoplasia is crucial. Two subtypes of sporadic gastric cancer have been recognized: cardia subtype and non-cardia (distal) subtype, the latter being more frequent and largely associated with infection of Helicobacter pylori, a class I carcinogen. Helicobacter pylori initiates the widely accepted Correa cascade, describing a stepwise progression through precursor lesions from chronic inflammation to gastric atrophy, gastric intestinal metaplasia and neoplasia. Our knowledge on He-licobacter pylori is still limited, and multiple questions in the context of its contribution to the pathogenesis of gastric neoplasia are yet to be answered. Awareness and recognition of gastric atrophy and intestinal metaplasia on high-definition white-light endoscopy, image-enhanced endoscopy and magnification endoscopy, in combination with histology from the biopsies taken accurately according to the protocol, are crucial to guiding the management. Standard indications for endoscopic resections (endoscopic mucosal resection and endoscopic submucosal dissection) of gastric dysplasia and intestinal type of gastric carcinoma have been recommended by multiple societies. Endoscopic evaluation and surveillance should be offered to individuals with an inherited predisposition to gastric carcinoma.

Abstract
Genome-wide association studies (GWASs) can reveal genetic variations associated with a phenotype in the absence of any hypothesis of candidate genes. The problem of false-positive sites linked with the responsible site might be bypassed in bacteria with a high homologous recombination rate, such as Helicobacter pylori, which causes gastric cancer. We conducted a small-sample GWAS (125 gastric cancer cases and 115 controls) followed by prediction of gastric cancer and control (duodenal ulcer) H. pylori strains. We identified 11 single nucleotide polymorphisms (eight amino acid changes) and three DNA motifs that, combined, allowed effective disease discrimination. They were often informative of the underlying molecular mechanisms, such as electric charge alteration at the ligand-binding pocket, alteration in subunit interaction, and mode-switching of DNA methylation. We also identified three novel virulence factors/oncoprotein candidates. These results provide both defined targets for further informatic and experimental analyses to gain insights into gastric cancer pathogenesis and a basis for identifying a set of biomarkers for distinguishing these H. pylori-related diseases.

Abstract
PURPOSE Perforated peptic ulcer (PPU) complicates 2 to 10% of patients with peptic ulcer disease and has mortality risk of up to 20%. Omental patch repair is the mainstay of surgical management and gastric resectional procedures are advocated for a large/giant ulcer or suspected malignancy. Emergency gastrectomy is associated with increased morbidity and mortality. The aim of this study is to compare the outcomes of omental patch repair with gastrectomy in patients with large PPU (≥ 20 mm). METHODS A retrospective review of all PPU patients who underwent surgery from January 2008 to December 2014 was done. Patients with PPU < 20 mm were excluded. Patient demographics and perioperative data were recorded. Length of hospital stay, post-operative complications, need for intensive care unit admission and all-cause mortality are reported. RESULTS 110 patients with a median age of 69.1 (range 28-90) years had PPU ≥ 20 mm. 42 (38.2%) patients presented within 24 h from the onset of abdominal pain. The median American Society of Anaesthesiology score was 3 (range 1-4). 52 patients had omental patch repair and 58 patients had gastrectomy. The overall incidence of intra-abdominal collection, post-operative leakage, re-operation and all-cause mortality was 16.4%, 11.8%, 6.4% and 19.1%, respectively. No difference in post-operative outcomes between the two groups was detected: intra-abdominal collection (p = 0.793), post-operative leakage (p = 0.813), re-operation (p = 0.809) and all-cause mortality (p = 0.736). CONCLUSION Omental patch repair confers similar perioperative outcomes as compared to gastrectomy in patients with large PPU.

Abstract
Gastric cancer, the fifth most frequent cancer and the fourth leading cause of cancer deaths, accounts for a devastating death rate worldwide. Since the majority of patients with gastric cancer are diagnosed at advanced stages, they are not suitable for surgery and present with locally advanced or metastatic disease. Recent advances in immunotherapy have elicited a considerable amount of attention as viable therapeutic options for several cancer types. This work presents a summary of the currently ongoing clinical trials and critically addresses the efficacy of a large spectrum of immunotherapy approaches in the general population for gastric cancer as well as in relation to tumor genetic profiling.

Abstract
IMPORTANCE Gastric cancer is one of the most common cancers, with a high mortality-to-incidence ratio. It is uncertain whether developed nations may encounter an increasing burden of gastric cancer in young adults, as occurs for other cancers. OBJECTIVES To evaluate the incidence and mortality of gastric cancer and compare the global incidence trends between younger (<40 years) and older (≥40 years) populations. DESIGN, SETTING, AND PARTICIPANTS This population-based cohort study analyzed data from global and national cancer registries, including data from 1980 to 2018, with at least 15 calendar years of incidence and mortality data. Data on age-standardized incidence and mortality rates of gastric cancer among 48 countries were retrieved from the Surveillance, Epidemiology, and End Results Program, the National Cancer Institute, the Nordic Cancer Registries, and the World Health Organization Mortality Database. The 10-year incidence trend of gastric cancer was assessed by age and sex. The 2018 GLOBOCAN database was used for reporting the global incidence and mortality of gastric cancer, the most recent data available at the time of analysis. Analyses were performed between January 10, 2020, and March 20, 2020. MAIN OUTCOMES AND MEASURES The average annual percent change (AAPC) of the incidence and mortality trends as evaluated by joinpoint regression analysis. RESULTS A total of 1 033 701 new cases of gastric cancer and 782 685 related deaths were reported in 2018. Overall, the incidence of gastric cancer decreased in 29 countries, and mortality decreased in 41 countries. The age-standardized incidence of gastric cancer decreased from a range of 2.6 to 59.1 in 1980 to a range of 2.5 to 56.8 in 2018 per 100 000 persons. The overall age-standardized mortality rate changed from a range of 1.3 to 25.8 in 1980 to a range of 1.5 to 18.5 in 2018 per 100 000 persons, but increasing mortality was observed in Thailand (female: AAPC, 5.30; 95% CI, 4.38-6.23; P < .001; male: AAPC, 3.92; 95% CI, 2.14-5.74; P < .001). The incidence of gastric cancer decreased in most regions among individuals 40 years or older and increased in populations younger than 40 years in several countries, including Sweden (male: AAPC, 13.92; 95% CI, 7.16-21.11; P = .001), Ecuador (female: AAPC, 6.05; 95% CI, 1.40-10.92; P = .02), and the UK (male: AAPC, 4.27; 95% CI, 0.15-8.55; P = .04; female: AAPC, 3.60; 95% CI, 3.59-3.61; P < .001). CONCLUSIONS AND RELEVANCE In this population-based cohort study, an increasing incidence of gastric cancer was observed in younger individuals in some countries, highlighting the need for more preventive strategies in younger populations. Future research should explore the reasons for these epidemiologic trends.

Abstract
Background Peptic ulcer disease (PUD) remains one of the most prevalent gastrointestinal diseases and has been linked to Helicobacter pylori (H. pylori) infection. This condition may be suspected on clinical grounds, but diagnosis is established using upper gastrointestinal endoscopy. Aims To determine the correlation between the endoscopic and pathological findings among suspected PUD patients who have been referred for diagnostic upper gastrointestinal endoscopy in National Hospital Abuja. Methods This is a hospital-based prospective study conducted among suspected PUD patients at National Hospital Abuja over a one-year period. Clinical, endoscopic, and histological findings were ascertained and documented. Data obtained were analyzed using SPSS version 21.0. Tests of significance were done using the chi-square test and Student t-test at 95% confidence intervals. Results One hundred and thirty-two patients were included in the study. The ages ranged from 15 to 87 years, mean age 43.30 ± 11.94 years. Seventy-seven (58.3%) patients had abnormal endoscopic findings, of whom 37 (28.0%) had PUD. Prevalence of H. pylori infection was 42.2% and was found in 81.1% of PUD patients. H. pylori was significantly associated with confirmed PUD (p < 0.001) and abnormal endoscopic findings (p < 0.001). No association was found between normal endoscopic findings and histological findings (p = 0.924). Conclusion There is a poor correlation between clinical and endoscopic diagnoses of PUD. H. pylori was found to be significantly associated with PUD and abnormal endoscopic findings. Endoscopic facilities should therefore be made available and accessible for proper PUD diagnosis. Empirical treatment of H. pylori in patients with diagnosed PUD is strongly recommended.

Abstract
Gastric cancer is the fifth leading cancer worldwide. Infection with Helicobacter pylori represents the major risk factor, but only a small fraction of infected individuals will develop neoplasia. The progression of advanced gastric lesions to cancer is influenced by characteristics of the bacterial strain, host genetic and environmental factors. Recently, the effect of medications on gastric cancer risk has gained interest, because many commonly prescribed drugs affect gastric homeostasis. While non-steroidal anti-inflammatory drugs (NSAIDs) are a frequent cause of gastric ulcer disease, low-dose aspirin has been propagated for chemoprevention of various tumour entities. Beneficial effects of cyclooxygenase-inhibition for gastric cancer prevention is plausible, but its clinical relevance remains unclear. Furthermore, anti-tumorous effects have been postulated for statins and metformin. On the contrary, proton pump inhibitors (PPIs), which are commonly used for prevention of gastric ulcers and bleeding, have been associated with an increased gastric cancer risk in large observational studies. Most of these observations still require confirmation in prospective controlled trials. NSAIDs, statins and metformin have also been investigated as concomitant cancer treatment, but studies did not show convincing results to date. Here, we review the available evidence and possible mechanisms for the role of PPIs, NSAIDs, statins and metformin in gastric carcinogenesis, and discuss possible implications for clinical practice.

Abstract
Helicobacter pylori infection is the most important etiological factor in gastroduodenal diseases development. Its evolution is influenced by several factors, including bacterial virulence genes such as cagA and cagE. This work aimed to evaluate the predictive value of cagE alone and in combination with cagA and CagA-EPIYA-C motifs number as a marker of the infection evolution. A total of 823 H. pylori DNA extracted from biopsies of consenting patients suffering from gastritis, peptic ulcer, or gastric cancer. The cagE, cagA status and cagA 3' region polymorphism were determined by PCR. The analysis shows that the risk of duodenal ulcer is 1.97-fold higher (CI = 1.18-3.30) in patients infected by strains cagA+/cagE+. And the risk of gastric cancer is 5.19-fold higher (CI = 1.18-22.70) in patients harboring strains cagE+/2EPIYA-C. The results suggest that cagE in combination with cagA-EPIYA-C motifs number can be used as predictive biomarker of H. pylori infection evolution.

Gastric adenocarcinoma and proximal polyposis of the stomach (GAPPS) - A Helicobacter-opposite point. Best Pract Res Clin Gastroenterol 2021; 50-51:101728.

Abstract
Gastric adenocarcinoma and proximal polyposis of the stomach (GAPPS) is a rare familial gastric cancer syndrome with an autosomal dominant pattern of inheritance. It is characterised by fundic gland polyposis of the gastric body and is associated with a significant risk of gastric adenocarcinoma. Unlike sporadic gastric cancer, Helicobacter pylori is usually absent in patients with GAPPS. This opposite-point finding has so far not been fully clarified. Prophylactic total gastrectomy is indicated in all cases of GAPPS with fundic gland polyposis and the presence of any dysplasia. If no dysplasia is found at histology, prophylactic gastrectomy is suggested at between 30 and 35 years of age, or at five years earlier than the age at which the youngest family member developed gastric cancer. Different phenotypes of GAPPS demand an individual approach to particular family members.

Abstract
Gastric cancer cases are often diagnosed at an advanced stage with poor prognosis. Platinum-based chemotherapy has been internationally accepted as first-line therapy for inoperable or metastatic gastric cancer. To achieve greater benefits, selection of patients eligible for this treatment is critical. Although gene expression profiling has been widely used as a genomic classifier to identify molecular subtypes of gastric cancer and to stratify patients for different chemotherapy regimens, its prediction accuracy can be improved. Adenosine-to-inosine (A-to-I) RNA editing has emerged as a new player contributing to gastric cancer development and progression, offering potential clinical utility for diagnosis and treatment. Using a systematic computational approach followed by both in vitro validations and in silico validations in The Cancer Genome Atlas (TCGA), we conducted a transcriptome-wide RNA editing analysis of a cohort of 104 patients with advanced gastric cancer and identified an RNA editing (GCRE) signature to guide gastric cancer chemotherapy. RNA editing events stood as a prognostic and predictive biomarker in advanced gastric cancer. A GCRE score based on the GCRE signature consisted of 50 editing sites associated with 29 genes, predicting response to chemotherapy with a high accuracy (84%). Of note, patients demonstrating higher editing levels of this panel of sites presented a better overall response. Consistently, gastric cancer cell lines with higher editing levels showed higher chemosensitivity. Applying the GCRE score on TCGA dataset confirmed that responders had significantly higher levels of editing in advanced gastric cancer. Overall, this newly defined GCRE signature reliably stratifies patients with advanced gastric cancer and predicts response from chemotherapy. SIGNIFICANCE: This study describes a novel A-to-I RNA editing signature as a prognostic and predictive biomarker in advanced gastric cancer, providing a new tool to improve patient stratification and response to therapy.

Exp Ther Med 2021; 21:329.

Abstract
Butyrate is one of the most abundant short-chain fatty acids produced by intestinal bacteria. In the present study, the action of butyrate on chronic gastric mucosa lesions was investigated, as well as its underlying mechanism in mice. Male mice from the Institute of Cancer Research were randomly divided into three groups: Sham, model and butyrate groups. Butyrate was administered intragastrically for 7 days to butyrate group mice following the establishment of a gastric ulcer model. Hematoxylin and eosin staining, immunohistochemical analysis, enzyme-linked immunosorbent assay and quantitative polymerase chain reaction were used to determine the therapeutic effects and molecular mechanism of butyrate treatment. The findings demonstrated that butyrate induced a marked shift in superoxide dismutase and catalase activities, along with a decrease in malondialdehyde levels, thereby attenuating oxidative stress. Furthermore, butyrate decreased the levels of pro-inflammatory cytokines interleukin-1β, tumour necrosis factor-α and leukotriene B4, which helped combat inflammatory responses. Moreover, butyrate treatment exerted remarkable positive influences that mediate an increase in 6-keto-PGF-1α (a degradation product of prostacyclin), trefoil factor 2, MUC5AC and fibroblast growth factor-7 levels to promote gastric mucosal repair. The expression of specific receptor GPR109A for butyrate was upregulated, with no significant difference noted in the expression of GPR43 or GPR41. Overall, the present findings revealed that butyrate exerted therapeutic effects by upregulating mucosal repair factors and stimulating protective responses against oxidation and inflammation. GPR109A may be the key receptor for butyrate therapy.

Abstract
BACKGROUND The genus Achillea L. is rich in bioactive sesquiterpenes and flavonoids; most of the studied species exhibit several biological activities and are used as emmenagogue, wound healing and analgesic agents. Some species are also used in local folklore medicine. OBJECTIVE Following a literature survey, we discuss the anti-cancer properties of Achillea species, taking into consideration ethnopharmacological data on their use in traditional medicine for the treatment of cancer. In addition, we screened extracts and isolated secondary metabolites from A. coarctata for cytotoxicity, upon information based on local traditional medicine. The plant was collected in Kozani (Northern Greece), where it is locally used for treating gastrointestinal disorders, including stomach cancer. METHODS A selection of the relevant data was performed through a search in PubMed, Scopus, Google Scholar and Science Direct databases. In addition, extracts and isolated compounds from A. coarctata were tested for their in vitro activity against the human cancer cell lines MCF-7 and HeLa. CONCLUSION The genus Achillea L. is a valuable source of bioactive secondary metabolites. The most significant outcome of the investigation of medicinal plants is the documentation and the assessment of the traditional information and its use and perspectives in the light of modern pharmacology.

Abstract
BACKGROUND While duodenal ulcer (DU) and gastric cancer (GC) are both H. pylori infection-related diseases, individuals with DU are known to have lower risk for GC. Many epidemiological studies have identified the PSCA rs2294008 T-allele as a risk factor of GC, while others have found an association between the rs2294008 C-allele and risk of DU and gastric ulcer (GU). Following these initial reports, however, few studies have since validated these associations. Here, we aimed to validate the association between variations in PSCA and the risk of DU/GU and evaluate its interaction with environmental factors in a Japanese population. METHODS Six PSCA SNPs were genotyped in 584 DU cases, 925 GU cases, and 8,105 controls from the Japan Multi-Institutional Collaborative Cohort (J-MICC). Unconditional logistic regression models were applied to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the association between the SNPs and risk of DU/GU. RESULTS PSCA rs2294008 C-allele was associated with per allele OR of 1.34 (95% CI, 1.18-1.51; P = 2.28 × 10-6) for the risk of DU. This association was independent of age, sex, study site, smoking habit, drinking habit, and H. pylori status. On the other hand, we did not observe an association between the risk of GU and PSCA SNPs. CONCLUSIONS Our study confirms an association between the PSCA rs2294008 C-allele and the risk of DU in a Japanese population.

Abstract
Peptic ulcer refers to the inflammatory response and necrotic lesions of the mucosa under the action of various pathogenic factors, which goes deeply into the mucosal muscle layer and often occurs to the gastrointestinal mucosa related to gastric acid secretion, among which the stomach and duodenum are the most common. The clinical manifestations include slow onset, prolonged course and weekly upper abdominal pain. Nitric oxide (NO) is an intracellular and intercellular signaling molecule that plays an important role in many physiological and pathological processes. Studies have found that a small amount of NO produced in vivo plays a role in many physiological homeostasis, such as regulating blood pressure, platelet aggregation, nitrogenization of hemoglobin, and regulating proliferation and differentiation of stem cells. However, under the action of some cytokines and oxidative stress, intracellular NO synthase will catalyze the synthesis of large amounts of NO and participate in the inflammatory response, causing beneficial or harmful effect on the body. Numerous basic studies have focused on the relationship between NO and peptic ulcer. The purpose of this review is to summarize the role of NO in peptic ulcer and its possible mechanism.

Hypergastrinemia is associated with an increased risk of gastric adenocarcinoma with proximal location: A prospective population-based nested case-control study. Int J Cancer 2020; 148:1879-1886. [PMID: 33091962 PMCID: PMC7984285 DOI: 10.1002/ijc.33354] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2020] [Revised: 10/12/2020] [Accepted: 10/14/2020] [Indexed: 12/15/2022]
Abstract
The incidence of proximal gastric adenocarcinoma is increasing among younger adults. Rodent models have shown that hypergastrinemia causes carcinogenesis in the proximal stomach. The aim of our study was therefore to assess if hypergastrinemia was associated with an increased risk of developing gastric adenocarcinoma also in humans. A prospective population‐based nested case‐control study within the Nord‐Trøndelag Health Study (HUNT) cohort, Norway, was used to assess this association. Serum was collected from 78 962 participants in 1995 to 1997 and 2006 to 2008. In the cohort, 181 incident gastric adenocarcinoma cases were identified from the Norwegian Cancer and Patient Registries through 2015 and matched with 359 controls. The risk of gastric adenocarcinoma was compared between participants with prediagnostic hypergastrinemia (>60 pmol/L) and normal serum gastrin (≤60 pmol/L). Logistic regression provided odds ratios (ORs) with 95% confidence intervals (CIs), adjusted for body mass index, tobacco smoking and comorbidity. Hypergastrinemia was associated with increased risk of gastric adenocarcinoma overall (OR 2.2, 95% CI 1.4‐3.4) and in particular for gastric adenocarcinoma with proximal location (OR 6.1, 95% CI 2.7‐13.8), but not with gastric adenocarcinoma with distal location (OR 1.7, 95% CI 0.9‐3.4). Moreover, hypergastrinemia was associated with an increased risk of gastric adenocarcinoma of intestinal histological type (OR 3.8, 95% CI 1.8‐7.9), but not for diffuse histological type (OR 1.6, 95% CI 0.7‐3.7). In conclusion, hypergastrinemia was associated with an increased risk of proximal and intestinal type gastric adenocarcinoma. What's new? The incidence of proximal gastric adenocarcinoma has been reported to increase among younger adults in Western countries. Rodent models have shown that serum gastrin levels above the normal range cause carcinogenesis in the proximal stomach. In this first prospective population‐based study on the association between hypergastrinemia and gastric adenocarcinoma, the risk of gastric adenocarcinoma in the proximal stomach, but not in the distal stomach, was markedly increased in hypergastrinemic individuals. The finding supports the hypothesis that hypergastrinemia mediates the development of gastric adenocarcinoma in the proximal stomach, where mucosal proliferation is stimulated by gastrin.

Park CH. Changes in Gastric Microbial Composition before and after Helicobacter pylori Eradication Therapy. THE KOREAN JOURNAL OF HELICOBACTER AND UPPER GASTROINTESTINAL RESEARCH 2020.

Abstract
Owing to advancements in next-generation sequencing and non-culture-based microbial research techniques, we have recognized that many bacterial taxa other than <i>Helicobacter pylori (H. pylori)</i> are present in the human stomach. Gastric microbial composition depends on gastric diseases, including gastritis, atrophic gastritis, intestinal metaplasia, and gastric cancer. Although <i>H. pylori</i> is a major factor associated with gastric cancer development, other bacterial taxa may affect gastric carcinogenesis. Because the risk of gastric cancer development can be reduced through <i>H. pylori</i> eradication, many investigators have studied the changes in the microbial composition in the stomach after <i>H. pylori</i> eradication. The gastric microbiome in patients with <i>H. pylori</i> infection typically shows abundance of <i>H. pylori</i> and a low microbial diversity index. If we treat <i>H. pylori</i>-infected patients with antibiotics, microbial diversity increases, and the relative abundance also increases in many bacterial taxa. Several studies suggested that the microbial composition in patients with <i>H. pylori</i> infection could be restored by <i>H. pylori</i> eradication therapy; however, there have been inconsistent findings of the abundant bacterial taxa after <i>H. pylori</i> eradication in patients with atrophic gastritis and intestinal metaplasia. More studies are required to reach a definitive conclusion on restoration of the microbial composition after <i>H. pylori</i> eradication according to the severity of gastric inflammation.
