A 36-year-old man with peptic ulcer disease presented to the emergency department with a 2-day history of haemoptysis and cough. Though he had no prior pulmonary symptoms, he noted progressive chest tightness and shortness of breath. He had no fever or night sweats. Vital signs were afebrile and

Although the mucosal barrier serves as a primary interface between the environment and host, little is understood about the repair of acute, superficial lesions or deeper, persistent lesions that if not healed, can be the site of increased permeability to luminal antigens, inflammation and/or neoplasia development.Recent studies have focused on focal adhesion kinase, which regulates controlled matrix adhesion during restitution after superficial injury. Actin polymerization regulates cell migration and the importance of actin-related proteins was also highlighted. Work on SARS-CoV-2 infection lent important new insights on gastroduodenal mucosal injury in patients with Covid-19 infection and work done with organoids and intestine-on-a-chip contributed new understanding about how coronaviruses infect gastrointestinal tissues and its resulting barrier dysfunction. A novel risk stratification paradigm was proposed to assist with decision making about repeat endoscopy for patients with gastric or duodenal ulcers and new therapeutic options were studied for ulcer disease. Lastly, work to support the mechanism of metaplasia development after deep injury and parietal cell loss was provided using novel transgenic mouse models.Recent studies highlight novel molecular targets to promote mucosal healing after injury of the gastroduodenal mucosa.

Contains fulltext : 287492.pdf (Publisher’s version ) (Open Access) INTRODUCTION: Unplanned hospital admissions associated with Parkinson's disease could be partly attributable to comorbidities. METHODS: We studied nationwide claims databases and registries. Persons with newly diagnosed Parkinson's disease were identified based on the first Parkinson's disease-related reimbursement claim by a medical specialist. Comorbidities were classified based on the Charlson Comorbidity Index. We studied hospitalization admissions because of falls, psychiatric diseases, pneumonia and urinary tract infections, PD-related hospitalizations-not otherwise specified. The association between comorbidities and time-to-hospitalization was estimated using Cox proportional hazard modelling. To better understand pathways leading to hospitalizations, we performed multiple analyses on causes for hospitalizations. RESULTS: We identified 18 586 people with newly diagnosed Parkinson's disease. The hazard of hospitalization was increased in persons with peptic ulcer disease (HR 2.20, p = 0.009), chronic obstructive pulmonary disease (HR 1.61, p

Weight reduction decreases gastroesophageal reflux disease (GERD), but laparoscopic sleeve gastrectomy (LSG) that damages the structure of the stomach may worsen GERD. We aimed to elucidate the factors associated with increased severity of erosive esophagitis (EE) at 1 year after LSG.Data on patients who underwent LSG between February 2007 and March 2016 were reviewed. Endoscopic findings and anthropometric data before and after surgery were recorded. The severity of EE was assessed according to the Los Angeles classification; severe EE was defined as grade C or D esophagitis.Totally, 316 patients were enrolled. Before LSG, 96 patients (30.4%) had grade A or B EE. One year after LSG, 215 patients (68%) had EE, including 136 (43%) with grade A, 62 (19.6%) with grade B, and 17 (5.4%) with grade C or D EE. One-hundred and twenty-seven of 220 patients (57.7%) without EE before LSG developed de novo EE following LSG. The incidence of severe EE after LSG in patients without pre-operative EE, grade A EE, or grade B EE at baseline was 3.2%, 6.8%, and 50%, respectively. Independent factors for an increased severity of EE after LSG were male gender (OR = 2.55, 95% CI = 1.52-4.28) and post-operative hiatal hernia (OR = 3.17, 95% CI = 1.66-6.06).The prevalence and severity of EE increased after LSG. Male gender and post-operative hiatal hernia are independent factors for an increased severity of EE after LSG. The incidence of severe EE after LSG is low for patients without pre-operative EE or grade A EE at baseline.

Marginal ulcers are a recognized complication of gastric bypass procedures for obesity. Perforated marginal ulcer (PMU) is a life-threatening complication of marginal ulcers. We performed a systematic review to understand the presentation, management, and outcomes of PMUs. PubMed, Google Scholar, and Embase databases were searched to identify all studies on PMUs after gastric bypass procedures. A total of 610 patients were identified from 26 articles. The mean age was 39.8±2.59 years, and females represented most of the cohort (67%). The mean body mass index was 43.2±5.67 kg/m

Gastrinoma may cause refractory esophageal stricture due to gastro-esophageal reflux disease (GERD), but imaging technologies have limited power in its diagnosis. A 74-year-old female with a history of peptic ulcers suffered from repeated epigastralgia, and she visited a local hospital. An esophago-gastro-duodenoscopy (EGD) demonstrated severe reflux esophagitis and multiple peptic ulcers. Blood examination revealed a high value of fasting serum gastrin. Multi-detector computed tomography showed a hypervascular and tiny nodule in duodenal bulb, although other imaging technologies did not. Short-term medication with a proton pump inhibitor or potassium-competitive acid blocker was intermittently provided, but dysphagia was repeatedly worsened, and she was referred to our division. Serum hypergastrinemia was retained, and EGD reexamination depicted esophageal stricture, treated by multiple sessions of endoscopic balloon dilatation. Primary tumor was not identified by the morphological imaging technologies, but a selective arterial secretagogue injection test suggested its existence in the duodenum or pancreatic head. Pancreaticoduodenectomy was performed, and histological study identified 2 mm-sized microgastrinoma buried in Brunner`s glands on the posterior wall of the duodenum bulb. We reported a case with difficulty in diagnosis of the smallest sporadic gastrinoma of the duodenum, which might cause refractory GERD-associated stricture.

The incidence rate of peptic ulcer is increasing gradually. Medical images can meet the needs of patients as an auxiliary diagnosis and treatment method for peptic ulcer. However, in the long-term treatment, the actual effect is average, and the diagnosis effect of gastrointestinal diseases will gradually deteriorate. In this paper, we use an image enhancement algorithm to study the mechanism of peptic ulcer from the perspective of a medical image. In this paper, 56 images of children with peptic ulcer were selected, and the gastroscopy based on the image enhancement algorithm provided technical support for the rapid diagnosis of patients with peptic ulcer. Experimental results show that the clinical features of peptic ulcer have different characteristics according to the age difference of patients, which can play a positive role in promoting the treatment of patients of different ages.

Peptic ulcer disease (PUD) is a common cause of hospitalization worldwide. We assessed temporal trends in hospitalization for PUD in 36 Organisation for Economic Co-operation and Development (OECD) countries since the turn of the 21st century.The OECD database contains data on PUD-related hospital discharges and mortality for 36 countries between 2000 and 2019. Hospitalization rates for PUD were expressed as annual rates per 100,000 persons. Joinpoint regression models were used to calculate the average annual percent change (AAPC) with 95% confidence intervals (CIs) for each country, which were pooled using meta-analyses. The incidence of PUD was forecasted to 2021 using autoregressive integrated moving average and Poisson regression models.The overall median hospitalization rate was 42.4 with an interquartile range of 29.7-60.6 per 100,000 person-years. On average, hospitalization rates (AAPC = -3.9%; 95% CI: -4.4, -3.3) and morality rates (AAPC = -4.7%; 95% CI: -5.6, -3.8) for PUD have decreased from 2000 to 2019 globally. The forecasted incidence of PUD hospitalizations in 2021 ranged from 3.5 per 100,000 in Mexico to 92.1 per 100,000 in Lithuania. Across 36 countries in the OECD, 329,000 people are estimated to be hospitalized for PUD in 2021.PUD remains an important cause of hospitalization worldwide. Reassuringly, hospitalizations and mortality for PUD have consistently been falling in OECD countries in North America, Latin America, Europe, Asia, and Oceania. Identifying underlying factors driving these trends is essential to sustaining this downward momentum.

Objective: Helicobacter pylori (Hp) and Epstein-Barr virus (EBV) are involved in gastric cancer (GC) etiology. EBV/Hp co- infection was thought synergistically increase gastroduodenal disease occurence. We aimed to determine the presence of EBV/Hp co-infection in gastroduodenal diseases. Methods: The study group had 68 Hp (+) cases [25 GC, 13 IM (intestinal metaplasia), 30 PU (peptic ulcer)], and the control group had 40 NUD (non-ulcer dyspepsia) cases [20 Hp+, 20 Hp-]. EBV-DNA was detected by non-polymorphic EBNA-1 gene-based qPCR. EBV/EBNA-1 IgG levels were determined by quantitative and qualitative ELISA methods, respectively. Results: EBV-DNA positivity was 32% (8/25), 6.6% (2/30) and 5% (1/20) in GC, PU and NUD Hp (+) cases, respectively. There was a significant difference (p = 0.001) between GC (32%) and NUD Hp (+) (5%) cases in terms of EBV-DNA positivity. Mean EBV-DNA copy numbers were 6568.54 ± 20351, 30.60 ± 159.88 and 13.85 ± 61.93 for GC, PU, and NUD, respectively. In terms of the mean EBV-DNA copy number, a significant difference was found between the groups (p = 0.005). In terms of EBV/EBNA-1 IgG antibody positivity, no significant difference was found between GC and NUD cases (p = 0.248). EBV DNA positivity was found to be significant (odds ration [OR] = 26.71 (p=0.009, %95CI 2.286- 312.041) in multivariate logistic regression. Conclusioin: Although we had a small number of GC cases, it can be suggested that the estimated risk created by the synergistic effect based on the addition of EBV increased 26 times in the presence of Hp in GC.

Background There are different methods to repair a perforated peptic ulcer, the two most frequently used are the Graham patch omentopexy and the primary closure. Currently there is no high-level evidence to provide guidance of the optimal method of repair. The aim of this study is to compare the outcomes of the two methods so as to provide improved guidance for surgeons undertaking this repair. Methods A systematic review and meta-analysis was conducted including any study that compared Graham patch omentopexy with primary closure in adults. Embase, Medline, Cochrane and Google's search engine were searched. The primary outcome was breakdown of the repair resulting in bile leak and the secondary outcomes were mortality, operation time, wound infection and time to start oral intake. The meta-analysis was conducted using Review Manager Software version 5:4. Outcome data were reported as odd ratios and weighted mean differences with their 95% confidence intervals. Results Of the 229 studies identified, 6 were suitable for analysis, 4 were retrospective, one was a prospective cohort study and one was a randomized controlled trial. Meta-analysis showed no difference in occurrence of bile leak or mortality between primary closure and Graham patch omentopexy (OR 0.64; 95% (0.26–1.54) & 0.66; 95% (0.25–1.76) respectively). There was no difference in the rates of wound infection OR 0.65; 95% (0.4–1.05). The duration of the operation was shorter in the primary closure group by 5.6 min; 95% (−21 + 10.4). Conclusion There was no difference in the clinical outcomes between the two modes of repair.

To determine the prevalence of endoscopic lesions unrelated with portal hypertension in patients with cirrhosis.Cross-sectional study including a consecutive cohort of patients with liver cirrhosis enrolled in a screening program of oesophageal varices who underwent an upper gastrointestinal endoscopy from November, 2013, to November, 2018. Clinical predictors of endoscopic lesions unrelated to portal hypertension were analyzed by univariate and multivariate logistic regression.A total of 379 patients were included. The most frequent aetiology of liver disease was alcohol consumption (60.4%). The prevalence of endoscopic lesions unrelated with portal hypertension was 39.6% (n=150). Among 96 patients with peptic lesions, urease was obtained in 56.2% of patients (positive in 44.4% of them). The prevalence of endoscopic lesions unrelated to portal hypertension was not associated with age, gender, liver function or ultrasound findings of portal hypertension. The prevalence of endoscopic lesions unrelated to portal hypertension was not associated with age, gender, liver function or ultrasound findings of portal hypertension. Smokers had a trend to increased prevalence of endoscopic lesions unrelated to portal hypertension (43.2% vs. 34.6%; p=0.09), particularly peptic ulcer (6.4% vs. 0.6%; p=0.05) and peptic duodenitis (17.3% vs. 6.3%; p=0.002). Active smoking was the only independent predictor of peptic ulcer or duodenitis (OR=2.56; p=0.017).Active smoking is a risk factor for endoscopic lesions unrelated to portal hypertension. This finding should be further investigated to reassess endoscopic screening programs in cirrhotic smokers.

Low-dose aspirin is a risk factor for peptic ulcer disease but previous, population-based cohort studies may have underestimated the low-dose aspirin risk because they did not use a new-user design. Gastrointestinal bleeding occurs more frequently early after initiation of low-dose aspirin therapy than in later years.To assess the associations of low-dose aspirin with gastric and duodenal ulcer incidence in prevalent- and new-user design.Multivariate Cox regression models in the German ESTHER study (N = 7737) and the UK Biobank (N = 213,598) with more than 10 years of follow-up.In the prevalent-user design, there was no significant association between low-dose aspirin and gastric ulcer observed in both cohorts. Furthermore, low-dose aspirin was weakly, statistically significantly associated with prevalent duodenal ulcer in the UK Biobank (hazard ratio [95% confidence interval]: 1.27 [1.07-1.51]) but not in the ESTHER study (1.33 [0.54-3.29]). When restricting the exposure to only new users, the hazard ratios for incident gastric and duodenal ulcer disease were 1.82 [1.58-2.11] and 1.66 [1.36-2.04] in the UK Biobank, respectively, and 2.83 [1.40-5.71] and 3.89 [1.46-10.42] in the ESTHER study, respectively.This study shows that low-dose aspirin is an independent risk factor for both gastric and duodenal ulcers. The associations were not significant or weak in the prevalent-user design and strong and statistically significant in the new-user design in both cohorts. Thus, it is important to weigh risks against benefits when low-dose aspirin treatment shall be initiated and to monitor adverse gastrointestinal symptoms after the start of low-dose aspirin therapy.

The purpose of this meta-analysis was to evaluate the efficacy and safety of proton pump inhibitors (PPIs) plus antithrombotic strategy in patients with coronary artery diseases compared with antithrombotic strategy alone. We searched PubMed, EMBASE, Cochrane Library, and Chinese Biomedical Medical Literature databases to retrieve randomized controlled trials investigating PPIs combined with antithrombotic strategy in coronary artery diseases. The primary efficacy outcome was major adverse cardiovascular and cerebrovascular events (MACCE). The primary safety outcome was gastrointestinal events. Secondary outcomes included all-cause death, cardiovascular death, myocardial infarction, stent thrombosis, significant bleeding from gastroduodenal lesions, and gastroduodenal ulcer. Overall, 43,943 patients were enrolled from 19 trials. The incidence of MACCE [relative risk (RR) 1.05; 95% confidence interval (CI) 0.96-1.15], all-cause death (RR 0.84; 95% CI 0.69-1.01), cardiovascular death (RR 0.88; 95% CI 0.69-1.12), myocardial infarction (RR 0.98; 95% CI 0.88-1.09), stent thrombosis (RR 1.01; 95% CI 0.76-1.34), and gastroduodenal ulcer (RR 0.40; 95% CI 0.13-1.29) did not increase significantly in patients receiving PPIs compared with patients without those. There were significant differences in the risk of gastrointestinal events (RR 0.34; 95% CI 0.21-0.54) and significant bleeding from gastroduodenal lesions (RR 0.09; 95% CI 0.03-0.28) between the 2 groups. In patients with coronary artery diseases, PPIs plus antithrombotic strategy could reduce the risk of gastrointestinal events and significant bleeding from gastroduodenal lesions but may not affect the incidence of MACCE, all-cause death, cardiovascular death, myocardial infarction, stent thrombosis, and gastroduodenal ulcer (PROSPERO: CRD42021277899, date of registration October 10, 2021).

Neurofibromatosis type (NF-1) is an autosomal dominant disorder characterized predominantly by neurocutaneous manifestations. Involvement of the gastrointestinal tract is uncommon but is associated with a significant risk of malignancy. There are a handful of case reports linking NF-1 with pancreatic neuroendocrine tumors; these include gastrin-secreting variants with the attendant Zollinger-Ellison syndrome. We present the case of a 52-year-old lady who presented with recurrent peptic ulceration and diarrhea. Serum gastrin levels were elevated and magnetic resonance imaging demonstrated the presence of a pancreatic lesion with multiple liver metastases. The lesion was moderately fludeoxyglucose avid on positron emission tomography-computed tomography. Endoscopic ultrasonography-guided sampling revealed the presence of synaptophysin positive neuroendocrine cells with positive gastrin immunostaining. A conservative approach was adopted, and the patient's symptoms improved on proton pump inhibitors. Zollinger-Ellison syndrome is an important condition, which should be kept in mind in the patient with NF-1 who presents with recurrent peptic ulceration and diarrhea. The emerging association between these 2 conditions is being examined on a cellular and immunohistochemical level.

BACKGROUND: Peptic ulcer disease (PUD), once primary a surgical problem, is now medically managed in the majority of patients. The surgical treatment of PUD is now strictly reserved for life-threatening complications. Free perforation, refractory bleeding and gastric outlet obstruction, although rare in the age of medical management of PUD, are several of the indications for surgical intervention. The acute care surgeon caring for patients with PUD should be facile in techniques required for bleeding control, bypass of peptic strictures, and vagotomy with resection and reconstruction. This video procedures and techniques paper demonstrates these infrequently encountered, but critical operations. CONTENT (VIDEO DESCRIPTION): A combination of anatomic representations and videos of step-by-step instructions on perfused cadavers will demonstrate the key steps in the following critical operations. Graham patch repair of perforated peptic ulcer is demonstrated in both open and laparoscopic fashion. The choice to perform open versus laparoscopic repair is based on individual surgeon comfort. Oversewing of a bleeding duodenal ulcer via duodenotomy and ligation of the gastroduodenal artery is infrequent in the age of advanced endoscopy and interventional radiology techniques, yet this once familiar procedure can be lifesaving. Repair of giant duodenal or gastric ulcers can present a challenging operative dilemma on how to best repair or exclude the defect. Vagotomy and antrectomy, perhaps the least common of all the aforementioned surgical interventions, may require more complex reconstruction than other techniques making it challenging for inexperienced surgeons. A brief demonstration on reconstruction options will be shown and includes Roux-en-Y gastrojejunostomy. CONCLUSIONS: Surgical management of PUD is reserved today for life-threatening complications for which the acute care surgeon must be prepared. This presentation provides demonstration of key surgical principles in management of bleeding and free perforation as well as gastric resection, vagotomy and reconstruction.

Background Peptic ulcer disease is one of the most common diseases in gastroenterology clinics. However, reported data about the global burden of peptic ulcer disease are still scarce. Methods This was a secondary data analysis on the prevalence, mortality and disability-adjusted life years (DALYs) due to peptic ulcer disease by sex, age group and socio-demographic index (SDI) at the global level in 21 regions and 204 countries and territories between 1990 and 2019 using the Global Burden of Diseases, Injuries, and Risk Factors Study 2019. Results Globally, the prevalence cases of peptic ulcer disease increased from 6 434 103 (95% uncertainty interval 5 405 963 to 7 627 971) in 1990 to 8 090 476 (6 794 576 to 9 584 000) in 2019. However, the age-standardized prevalence rate decreased from 143.4 (120.5 to 170.2) per 100 000 population in 1990 to 99.4 (83.9 to 117.5) per 100 000 population in 2019. Moreover, the age-standardized mortality rate decreased by 59.4% (55.3 to 63.1) and the DALYs rate fell by 60.6% (56.8 to 63.9) from 1990 to 2019. Across SDI quintiles, low-middle and low SDI quintiles had the highest age-standardized prevalence, mortality and DALYs rates from 1990 to 2019. Conclusion The age-standardized prevalence, mortality and DALYs estimates of peptic ulcer disease decreased from 1990 to 2019 globally, but more efforts are needed for the prevention, early diagnosis and treatment of peptic ulcer disease in low SDI and low-middle SDI groups of countries.

Non-steroidal antiinflammatory drugs (NSAIDs) are currently one of the most widely used drugs. The use of NSAIDs is associated with gastrointestinal toxicity, affecting both upper gastrointestinal tract (peptic ulcer disease) and lower gastrointestinal tract (NSAID-induced enteropathy). NSAIDs use has been associated with an increased risk of clinical relapse in inflammatory bowel disease patients. In this article, we review the upper and lower gastrointestinal toxicity of NSAIDs, with a focus on the risks and specific data of these drugs in inflammatory bowel disease patients, giving recommendations for its appropriate use in the clinical practice. Although evidence is scarce, short-term use of NSAIDs appears to be safe, and the data available suggest that selective COX-2 inhibitors are the safer option. NSAIDs should be avoided as long-term treatment or with high doses, especially in patients with active inflammation.

Proton pump inhibitors are widely used throughout the world for the treatment of gastrointestinal disorders that are related to acid secretion, such as peptic ulcer disease and dyspepsia. Another common indication for proton pump inhibitors is stress ulcer prophylaxis. Proton pump inhibitors have proven efficacy for the treatment of acid-related gastrointestinal disorders, but there is concern that their use may be associated with the development of significant complications, such as fractures, Clostridium difficile infection, acute kidney injury, chronic kidney disease, and hypomagnesemia. Proton pump inhibitors are overused in the hospital setting, both for stress ulcer prophylaxis and gastrointestinal bleeding, and then they are often inappropriately continued after discharge from the hospital. This narrative review article outlines the evidence surrounding appropriate proton pump inhibitor use for stress ulcer prophylaxis and peptic ulcer bleeding.

To assess of the ten-year dynamics of cases of hospitalizations of patients with peptic ulcer disease (PUD), chronic gastritis and chronic duodenitis relative to the total number of people treated in the gastroenterological departments of the hospital in 20102019.Data of the annual reports of the work of the hospital departments were studied retrospectively.The relative number of persons hospitalized for chronic duodenitis decreased 2.8 times (p0.001), but the proportion of patients with chronic gastritis did not tend to decrease. This is most likely due to diagnostic errors. The cases of hospitalization of persons with uncomplicated PUD decreased by 3.1 times (p0.001), the proportion of men with duodenal ulcer decreased by 6.3 times (p0.001), with gastric ulcer decreased 1.9 times (p0.01). The proportion of women hospitalized with duodenal ulcer decreased 2.3 times (p0.01). The number of hospitalized men with duodenal ulcer is 3.8 times more than females (p0.001). It can be explained by a decrease in social stressful influences and active anti-Helicobacter pylori therapy.Over the period of follow-up, the cases of hospitalization of patients with uncomplicated PUD decreased, primarily due to a decrease in the proportion of persons with ulcer of the duodenum and duodenitis, while the number of patients with chronic gastritis not undergoing modern examination did not have significant dynamics.Цель. Оценить10-летнюю динамику количества случаев госпитализации пациентов с язвенной болезнью (ЯБ), хроническим гастритом и хроническим дуоденитом относительно общего числа лиц, пролеченных в гастроэнтерологических отделениях больницы в 20102019 гг. Материалы и методы. Ретроспективно изучались данные годовых отчетов работы отделений больницы. Результаты. Относительное число лиц, госпитализированных по поводу хронического дуоденита, снизилось в 2,8 раза (p0,001), но доля пациентов с хроническим гастритом не имела тенденции к уменьшению. Вероятнее всего, это связано с ошибками диагностики. Количество случаев госпитализации лиц с неосложненной ЯБ уменьшилось в 3,1 раза (p0,001), доля мужчин с ЯБ двенадцатиперстной кишки (ДПК) уменьшилась в 6,3 раза (p0,001), с ЯБ желудка уменьшилась в 1,9 раза (p0,01). Доля госпитализированных женщин с ЯБ ДПК уменьшилась в 2,3 раза (p0,01). Число госпитализированных мужчин с ЯБ ДПК больше, чем женщин, в 3,8 раза (p0,001), что может объясняться уменьшением социальных стрессовых влияний и активной антихеликобактериальной терапией. Заключение. За период наблюдения количество случаев госпитализации пациентов с неосложненной ЯБ уменьшилось прежде всего за счет снижения доли лиц с ЯБ ДПК и дуоденитом, в то время как число пациентов с хроническим гастритом, не проходящих современного обследования, не имело достоверной динамики.

Helicobacter pylori is a spiral-shaped gram-negative bacterium that colonizes the stomach lining. The presence of a microorganism in humans was described more than a century ago, but from detection to recognition of its role in the etiology and pathogenesis of diseases of the stomach, researchers had to overcome a long path of criticism and mistrust. Coiled bacteria have been mentioned several times in the medical literature, but these bacteria were thought to be contaminants, and any evidence of the bacteria in the stomach was ignored by the medical community. The discovery of H. pylori led to a revolutionary rethinking of the mechanisms of development of a number of diseases: the role of bacteria in the development of chronic gastritis, peptic ulcer disease, stomach cancer and MALT lymphoma was proved. The principles of their prevention and treatment have changed. For this discovery in 2005, Barry Marshall and Robin Warren were awarded the Nobel Prize in Medicine and Physiology.Helicobacter pylori спиралевидная грамотрицательная бактерия, которая колонизирует слизистую оболочку желудка. Присутствие микроорганизма у человека было описано более века назад, но от момента обнаружения до признания ее роли в этиологии и патогенезе заболеваний желудка исследователям пришлось преодолеть долгий путь критики и недоверия. Спиралевидные бактерии неоднократно упоминались в медицинской литературе, однако считалось, что они являлись контаминантами, и любые свидетельства наличия бактерии в желудке игнорировались медицинским сообществом. Открытие Н. pylori привело к революционному переосмыслению механизмов развития ряда заболеваний: была доказана роль бактерии в развитии хронического гастрита, язвенной болезни, рака желудка и MALT-лимфомы. Изменились принципы их профилактики и лечения. За это открытие Барри Маршалл и Робин Уоррен были удостоены Нобелевской премии в области медицины и физиологии в 2005 г.

Background Peptic ulcer disease (PUD) is a common digestive disorder, of which the prevalence decreased in the past few decades. However, the decreasing tendency has plateaued in recent years due to changes in risk factors associated with the etiology of PUD, such as non-steroidal anti-inflammatory drug use. In this study, we investigated the epidemiological and the sociodemographic characteristics of PUD in 204 countries and territories from 1990 to 2019 based on data from the Global Burden of Disease, Injuries and Risk Factors (GBD) Study. Methods Demographic characteristics and annual prevalence, incidence, mortality, disability-adjusted life years (DALYs) and age-standardized death rate (ASR) data associated with PUD were obtained and analyzed. According to the sociodemographic index (SDI), the numbers of patients, ASRs, estimated annual percentage changes and geographical distributions were assessed with a generalized linear model and presented in world maps. All evaluations of numbers and rates were calculated per 100,000 population with 95% uncertainty intervals (UIs). Results In 2019, the global prevalence of PUD was approximately 8.09 [95% UI 6.79–9.58] million, representing a 25.82% increase from 1990. The age-standardized prevalence rate was 99.40 (83.86–117.55) per 100,000 population in 2019, representing a decrease of 143.37 (120.54–170.25) per 100,000 population from 1990. The age-standardized DALY rate in 2019 was decreased by 60.64% [74.40 (68.96–81.95) per 100,000 population] compared to that in 1990. In both sexes, the numbers and ASRs of the prevalence, incidence, deaths and DALYs were higher in males than in females over 29 years. Regionally, South Asia had the highest age-standardized prevalence rate [156.62 (130.58–187.05) per 100,000 population] in 2019. A low age-standardized death rate was found in the high-income super-region. Among nations, Kiribati had the highest age-standardized prevalence rate [330.32 (286.98–379.81) per 100,000 population]. Regarding socioeconomic status, positive associations between the age-standardized prevalence, incidence, death rate, DALYs and SDI were observed globally in 2019. Conclusions Morbidity and mortality due to PUD decreased significantly from 1990 to 2019, while a gradual upward inclination has been observed in recent 15 years, which might be associated with changes in risk factors for PUD. Attention and efforts by healthcare administrators and society are needed for PUD prevention and control.

Objective. Periodontitis is a highly prevalent oral infectious disease and has been increasingly associated with H. pylori infection, gastric inflammation, and gastric cancer but little is known about epigenetic machinery underlying this potentially bidirectional association. The present study is aimed at identifying key deregulated miRNA, their associated genes, signaling pathways, and compounds linking periodontitis with H. pylori-associated peptic ulcer disease. Methods. miRNA expression datasets for periodontitis-affected and H. pylori-associated peptic ulcer disease-affected tissues were sought from the GEO database. Differentially expressed miRNA (DEmiRNAs) were identified and the overlapping, shared-DEmiRNA between both datasets were determined. Shared-DEmiRNA-target networks construction and functional analyses were constructed using miRNet 2.0, including shared-DEmiRNA-gene, shared-DEmiRNA-transcription factor (TF), and shared-DEmiRNA-compound networks. Functional enrichment analysis for shared DEmiRNA-gene and shared DEmiRNA-TF networks was performed using the KEGG, Reactome, and Geno Ontology (GO) pathways. Results. 11 shared-DEmiRNAs were identified, among which 9 showed similar expression patterns in both diseases, and 7 were overexpressed. miRNA hsa-hsa-mir-155-5p and hsa-mir-29a-3p were top miRNA nodes in both gene and TF networks. The topmost candidate miRNA-deregulated genes were PTEN, CCND1, MDM2, TNRC6A, and SCD while topmost deregulated TFs included STAT3, HIF1A, EZH2, CEBPA, and RUNX1. Curcumin, 5-fluorouracil, and the gallotanin 1,2,6-Tri-O-galloyl-beta-D-glucopyranose emerged as the most relevant linkage compound targets. Functional analyses revealed multiple cancer-associated pathways, PI3K pathways, kinase binding, and transcription factor binding among as enriched by the network-associated genes and TFs. Conclusion. Integrative analysis of deregulated miRNAs revealed candidate molecular mechanisms comprising of top miRNA, their gene, and TF targets linking H. pylori-infected peptic ulcer disease with periodontitis and highlighted compounds targeting both diseases. These findings provide basis for directing future experimental research.

Upper gastrointestinal (GI) bleeding is a common presentation in emergency departments (EDs). This medical emergency has a mortality rate of up to 14%, particularly in men and older people. The most frequent cause of upper GI bleeding is peptic ulcer disease. Management has not changed significantly in the past 50 years and there is ongoing debate in the literature about the most effective treatment protocols. This article uses a case study of a patient who presented to an ED with upper GI bleeding caused by peptic ulcer disease to examine the evidence on treatment and management. The article also discusses a care bundle that has been developed for rapid assessment and management of patients with acute upper GI bleeding.

Helicobacter pylori is an organism associated with ulcer disease and gastric cancer. The latter is one of the most prevalent malignancies and currently the fourth major cause of cancer-related deaths globally. The pathogen infects about 50% of the world population, and currently, no treatment ensures its total elimination. There has been an increase in our understanding of the pathophysiology and pathogenesis mechanisms of H. pylori over the years. H. pylori can induce several genetic alterations, express numerous virulence factors, and trigger diverse adaptive mechanisms during its adherence and colonization. For successful colonization and infection establishment, several effector proteins/toxins are released by the organism. Evidence is also available reporting spiral to coccoid transition as a unique tactic H. pylori uses to survive in the host’s gastrointestinal tract (GIT). Thus, the virulence and pathogenicity of H. pylori are under the control of complex interplay between the virulence factors, host, and environmental factors. Expounding the role of the various virulence factors in H. pylori pathogenesis and clinical outcomes is crucial for vaccine development and in providing and developing a more effective therapeutic intervention. Here we critically reflect on H. pylori infection and delineate what is currently known about the virulence and pathogenesis mechanisms of H. pylori.

Background: Histamine-2-receptor antagonists (H2RAs) have been largely replaced by proton pump inhibitors (PPIs) for stress ulcer prophylaxis (SUP) despite the inconclusive evidence concerning comparative effectiveness. Objective: To compare the effectiveness of PPIs and H2RAs on SUP in real-world setting. Methods: PubMed, Embase, and the Cochrane Library were searched from inception to September 19, 2021. We included cohort studies comparing PPIs with H2RAs in critically ill adult patients and explicitly reporting the outcome of gastrointestinal (GI) bleeding or mortality. Newcastle-Ottawa Scale was used to assess potential risk of bias. We conducted a random-effects meta-analysis and only the studies with adjusted effect estimates were pooled. The Grading of Recommendations Assessment, Development, and Evaluation system was used to assess the overall quality of the evidence. Results: Thirteen cohort studies (N = 145 149) were eligible and 11 of them available for full texts were of low to moderate risk of bias. Meta-analysis of adjusted effect estimates indicated that PPIs were associated with a significantly higher risk of GI bleeding, compared with H2RAs (8 studies, odds ratio [OR] = 1.98, 95% confidence interval [CI] = 1.30-3.01, low certainty). Post hoc pooling analysis also suggested that PPIs were associated with a slightly higher risk of mortality in comparison with H2RAs (7 studies, OR = 1.27, 95% CI = 1.13-1.42, low certainty). Conclusion and Relevance: The systematic review of cohort studies showed that PPIs were associated with higher risks of GI bleeding and mortality, although the certainty of evidence was low. Overall, we suggest not excluding H2RAs for SUP, while further studies are essential for elucidating the risk stratification, optimal regimen, and specific duration.

During the last decades, Chinese medicine has been widely used for curing various diseases in the healthcare domain. Based on the databases of medicine wisdom and modern application of prescriptions, we have explored the medication pattern of ancient and modern prescriptions for the treatment of peptic ulcer in various patients. In this paper, we have proposed a neural network model which is based on the time series decomposition and is able to mine and predict the medication pattern of peptic ulcer treatment in Chinese medicine. For this purpose, cumulative distance level method, Mann–Kendall trend analysis, Hurst exponent, and characteristic point methods are used for the trend analysis. Likewise in the proposed model, the wavelet analysis method is used for the periodicity analysis and Mann–Kendall mutation test method along with Pettitt methods is used for mutability analysis. In addition, autocorrelation and unit root methods are utilized to test the random terms. The Chinese herbal formulas (where the main diseases are peptic ulcer, peptic ulcer, cerebral leakage, and cerebral abscess) are collected from the databases of medicine wisdom and modern application of prescriptions. Furthermore, methods of frequency analysis, association rule analysis, and factor analysis are used to evaluate the grouping pattern of prescriptions for peptic ulcer treatment. The error in the proposed scheme between the predicted and the measured values of 87 prescriptions, which involve five Chinese medicines for peptic ulcer and 160 Chinese medicines, obtained from the neural network was 16.79%.

Background There are limited studies regarding the impact of post-operative leak on perforated peptic ulcer disease (PPUD) and conflicting results regarding routine drain placement in operative repair of PPUD. This study aims to identify risk factors for gastrointestinal leak after operative repair of PPUD to better guide intra-operative decisions about drain placement. Methods We performed a retrospective cohort study at a tertiary care center from 2008 to 2019, identifying 175 patients who underwent operative repair of PPUD. Results Patients who developed a leak (17%) were compared to patients who did not. Both hypoalbuminemia (albumin < 3.5 g/dL) ( P = .03) and duodenal ulcers ( P < .01) were identified as significant risk factors for leak. No significant difference was found between leak and no leak groups for AAST disease severity grade, repair technique, or pre-operative use of tobacco, alcohol, or steroids. Post-operative leaks were associated with prolonged hospital stay (29 days compared to 10, P < .01), increased complication rates (77% compared to 48%, P < .01), and increased re-operation rates (73% compared to 26%, Discussion Leak after operative PPUD repair is associated with significant post-operative morbidity. Hypoalbuminemia and duodenal perforations are significant risk factors for post-operative leaks.

Background Perforated peptic ulcer is a morbid emergency general surgery condition. Best practices for postoperative care remain undefined. Surgical dogma preaches practices such as peritoneal drain placement, prolonged nil per os, and routine postoperative enteral contrast imaging despite a lack of evidence. We aimed to evaluate the role of postoperative enteral contrast imaging in postoperative perforated peptic ulcer care. Our primary objective was to assess effects of routine postoperative enteral contrast imaging on early detection of clinically significant leaks. Methods We conducted a multicenter retrospective cohort study of patients who underwent repair of perforated peptic ulcer between July 2016 and June 2018. We compared outcomes between those who underwent routine postoperative enteral contrast imaging and those who did not. Results Our analysis included 95 patients who underwent primary/omental patch repair. The mean age was 60 years, and 54% were male. Thirteen (14%) had a leak. Eighty percent of patients had a drain placed. Nine patients had leaks diagnosed based on bilious drain output without routine postoperative enteral contrast imaging. Use of routine postoperative enteral contrast imaging varied significantly between institutions (30%–87%). Two late leaks after initial normal postoperative enteral contrast imaging were confirmed by imaging after a clinical change triggered the second study. Two patients had contained leaks identified by routine postoperative enteral contrast imaging but remained clinically well. Duration of hospital stay was longer in those who received routine postoperative enteral contrast imaging (12 vs 6 days, median; P = .000). Conclusion Routine postoperative enteral contrast imaging after perforated peptic ulcer repair likely does not improve the detection of clinically significant leaks and is associated with increased duration of hospital stay.

Since December 2019, the novel coronavirus has spread worldwide, affecting more than 510 million people, with more than 6 million deaths. However, some of the potential effects of the pandemic have not been thoroughly studied. We collected data from 2 regional emergency centers from May to November for the years 2015 to 2019, before the pandemic, and from May to November 2020, after the pandemic. We evaluated the incidence of each major type of digestive disease before and after the pandemic in adults at the 2 hospitals, which experienced coronavirus disease 2019 outbreaks with varying severity. A total of 11,394 patients were enrolled in the study Affiliated Hospital of Putian University (PUTIAN, n = 5503) Union Hospital, Tongji Medical college, Huazhong University of Science and Technology (UNION, n = 5891), and the proportion of male patients was approximately the same at both hospitals, with 3360 (61.1%) and 3680 (62.5%), respectively. The average ages of the patients were 55.8 ± 18.4 years PUTIAN and 54.3 ± 15.8 years UNION. The numbers of patients at the 2 hospitals increased steadily, but in 2020, the number of patients at UNION declined. The baseline characteristics of the 2 groups at the 2 hospitals showed significant differences for age before and after the pandemic but not for sex. The constituent ratios of diseases in each year in the 2 hospitals differed. The number of patients with peptic ulcers in 2020 was significantly different from those in each year from 2015 to 2019 (PUTIAN 2015-2020, 15.0%, 18.2%, 14.9%, 16.9%, 19.5%, 34.9%; UNION 2015-2020, 29.2%, 32.5%, 29.3%, 29.4%, 29.7%, 41.3%, respectively). The rates of peptic ulcer increased dramatically in both hospitals in 2020. An increase in the incidence of severe peptic ulcer was observed after the pandemic compared to the same period before the pandemic. Therefore, these factors should be considered in the formulation of public health strategies and the allocation of medical resources in the post pandemic era.

Various international guidelines have been developed regardingA cross-sectional study was conducted among medical doctors currently working in Khartoum, Sudan. Participants were enrolled from platforms of medical associations through an online questionnaire. The questionnaire was scored out of 25 points, and scoring 13 or above considered a good approach. Data analysis was carried out using Statistical Package for Social Sciences (SPSS).A total of 358 medical doctors participated in the study. The mean (±SD) score was 12.9(±4.5). Those who were using textbooks, campaigns, symposiums or general medical information to their primary Source of knowledge significantly scored higher. The most selected indication for both diagnosis (76.8%) and treatment (67.6%) was an active peptic ulcer. Stool antigen test (SAT) was the most preferred test (70.7%). The majority of respondents selected triple therapy (82.1%) as a first-line regimen. Only 37.7% confirmed the eradication after four weeks of stopping the treatment. They ensure eradication mainly through SAT (29%).A suboptimal approach was noted among medical doctors of Khartoum, Sudan, regarding

This study investigates the incidence and risk factors of new vertebral body collapse (VC) after posterior instrumented spinal fusion in patients older than 70 years. This retrospective study analyzed the data of elderly patients who underwent posterior instrumented spinal fusion in the thoracolumbar spine between January 2013 and December 2017. The 2 subsamples comprised of patients who had experienced vertebral compression fracture (VCF) before the index spinal surgery (group 1, n = 324) and those who had not (group 2, n = 1040). We recorded and analyzed their baseline characteristics, their underlying comorbidities, and the details of their current instrumented spinal fusion. The incidences of new VC and screw loosening were recorded. In groups 1 and 2, the incidences of new VC were 31.8% and 22.7%, respectively, and those of new VC with screw loosening were 25.6% and 33%, respectively. The risk factor was upper screw level at the thoracolumbar junction (hazard ratio [HR] = 2.181, 95% confidence interval [CI]: 1.135-4.190) with previous VCF. The risk factors were age ≥ 80 years (HR = 1.782, 95% CI: 1.132-2.805), instrumented levels 4 (HR = 1.774, 95% CI: 1.292-2.437), and peptic ulcer (HR = 20.219, 95% CI: 2.262-180.731) without previous VCF. Clinicians should closely monitor new VC after posterior instrumented spinal fusion in elderly patients with previous VCF with upper screw level at the thoracolumbar junction and in patients without previous VCF aged ≥ 80 years, with instrumented levels 4 and peptic ulcer.
