RESUMEN
Background and Aims: Inflammatory bowel disease (IBD) is a chronic inflammatory gastrointestinal tract disease subdivided into Crohn's disease (CD) and ulcerative colitis (UC). There is currently no cure for IBD, and individuals with IBD frequently experience a lower health-related quality of life (HRQOL) than the general population. Gamification has become an increasingly popular topic in recent years. Adapting game design concepts to nongaming contexts represents a novel and potential approach to changing user engagement. This study will be conducted with the aim of evaluating the effect of a gamified mobile-based self-management application on disease activity index, quality of life, and mental health in adults with IBD. Methods: A multicenter, parallel, two-arm, exploratory randomized controlled trial with a 6-month follow-up per patient will be designed to compare the impact of the gamified mobile-based tele-management system on primary and secondary health outcomes and outpatient visits in 210 patients with all types of IBD which are divided equally into a control group with standard care and an intervention group which will use the developed mobile application named MY IBD BUDDY. All patients will attend study visits at baseline, 12 and 24 weeks, and routine IBD clinic visits or telephone consultations based on randomization group assignment. Disease activity or disease activity index, mental health (anxiety and depression) symptoms, quality of life, self-efficacy, and IBD-specific knowledge will be measured at baseline with two follow-ups at 12 and 24 weeks. Conclusions: In sum, the outcomes of our trial will demonstrate the impact of the gamified mobile-based self-management system on disease activity, quality of life, and anxiety and depression by means of interactive care and patient empowerment.

RESUMEN
Background: Colorectal cancer could be developed from adenomatous polyp. The study aimed to evaluate the diagnostic significance of stromal and epithelial CD10 (Neprilysin) expression in patients with colorectal adenocarcinoma and adenomatous polyps. Methods: This cross-sectional study was conducted on 141 patients with colorectal adenocarcinoma and adenomatous polyps referred to Ayatollah Rouhani Hospital from March 2020 to March 2021. Differential diagnoses of colorectal adenocarcinoma and adenomatous polyps were made colonoscopically, and then samples were taken from the lesions. The pathologists confirmed the final diagnosis as colorectal adenocarcinoma, high-grade or low-grade adenomatous polyps. The stromal and epithelial CD10 expression was evaluated by immunohistochemistry. The data was analyzed by SPSS 22 software (p<0.05). Results: Sixty-five (46.1%) of the cases were low-grade polyps that were included positive (4 cases; 6.20%) and negative (61 cases; 93.80%) CD10 expression (P=0.001), also 76 (53.9%) of them were either high-grade polyps (21 cases) or adenocarcinomas (21 cases). Also, epithelial CD10 expression was significantly higher in the well-differentiated adenocarcinoma (38 cases) group than moderate (13 cases) and poor (4 cases) groups (P =0.001). Moreover, the CD10 expression level in the adenomatous polyps (10 positive cases and 76 negative cases) was correlated with the degree of dysplasia (P = 0.001) and the presence of tumor invasion (8 positive cases and 133 negative cases) (P = 0.001). Conclusion: The CD10 expression is associated with an increased degree of dysplasia and the presence of tumor invasion in patients with pre-neoplastic lesions and colorectal adenocarcinoma.
RESUMEN
BACKGROUND: Self-management education resources for inflammatory bowel disease (IBD) using concepts remain infrequent. We aim to describe the development and evaluation process of educational material for self-management in IBD based on patient preferences and expert opinions. RESEARCH DESIGN AND METHODS: The method of this study includes two main phases of development and validation in five steps in the following order: (1) identification of information needs for patients with IBD; (2) content development with a comprehensive literature review and scientific texts related to IBD; (3) measuring the face validity of the content based on the expert opinions in the field of IBD; (4) validation of the content with the experts in the field of IBD; and (5) validation by target audiences. RESULTS: The expert panel comprises ten gastroenterologists, nutritionists, psychologists, gynecologists, and nurses. The total suitability score is 79.5%. The final draft version of the educational self-management material was presented to 30 IBD patients who were satisfied (n = 24; 80%) with the material. CONCLUSIONS: This study shows the development process and is validated for face and content validity by the academic multidisciplinary expert panel and target group. Patients and their caregivers can use this content to cope with their disease.
RESUMEN
Background: Inflammatory Bowel Disease (IBD) affects the quality of life. Patient education and support needs are crucial components of comprehensive chronic illness care. The main purposes of this review were to (i) explore the informational and supportive needs of these patients to improve the quality of life in the existing literature and (ii) identify the gaps related to the needs of the patients in articles. Methods: The scoping review is based on the Daudt methodological framework, a modified version of Arksey and O'Malley. Electronic databases were extensively searched from January 01, 2000 to April 30, 2022. Four electronic databases (PubMed/Medline, CINAHL, APA PsycInfo, Psychology and Behavioral Sciences Collection, APA PsycArticles, and ProQuest) were searched using controlled vocabulary, and specific keywords. The searched terms were matched to each database. We manually searched two key journals, namely the Journal of Inflammatory Bowel Disease and the Journal of Crohn's and Colitis. Results: In the review, 75 studies on the assessment of the information and support needs of patients with IBD were reviewed. In this regard, 62 and 53 studies were regarding information needs and support needs, respectively. Most of the information needs of patients with IBD reported in the studies were related to diet needs, and educational needs were the most essential support needs. Conclusions: Health policymakers and managers can develop care and educational programs related to this disease in health centers according to the needs of the patients. Health professionals, especially gastroenterologists, are the primary referral sources for information on patients. Therefore, gastroenterologists can take the lead in planning and educating the patients and sharing their decisions. Systematic review registration: OSF, https://doi.org/10.17605/OSF.IO/3MWGJ.
RESUMEN
Helicobacter Pylori (H. Pylori) cause peptic ulcer disease (PUD), but the inflammasome's role in PUD is not well understood. Therefore this study has investigated inflammasome compartment expression and IL-1ß production in gastritis (G) and peptic ulcer disease. This study was based on gene expression of inflammasome compartments on stomach biopsies of 50 patients with PUD as cases and 50 individuals with gastritis as controls. The expression of NLRC4, ASC, IL-18, and serum IL-1ß decreased in the PUD group compared to the control group. AIM2 gene expression increased, and NLRP12 gene expression decreased in H. pylori-seropositive positive (HP+ ) individuals compared to H. pylori-seronegative (HP- ) individuals. The G-HP+ subjects had higher serum IL-1ß and AIM2 gene expression than G-HP- subjects but lower NLRP3 and NLRP12 gene expression. The PUD-HP+ had lower serum IL-1ß, but higher AIM2 and IL-18 expression than PUD-HP- . The PUD-HP- patients had decreased IL-18 expression than G-HP- group. The PUD-HP+ had lower serum IL-1ß and NLRC4 expression than G-HP+, while NLRP1 and NLRP3 were higher in expression in PUD-HP+ . The expression of caspase-1, NLRP3 and NAIP were correlated with IL-1ß and IL-18. In conclusion, a decrease in NLRC4, IL-18, ASC genes, and IL-1ß levels in PUD patients compared to gastritis may act in the development of PUD. H. pylori caused AIM2 induction and reduced NLRP12, indicating their contribution to bacterial responses. Decreased NLRC4 expression and IL-1ß protein, together with enhanced NLRP1, and NLRP3 expression, promotes H. pylori to develop peptic ulcers.

Background: Helicobacter pylori infection is the most common cause of peptic ulcer disease. However, the prevalence rates of non-helicobacter pylori idiopathic peptic ulcers have increased over the past few years. This study aims to compare the characteristics of Helicobacter pylori-positive with idiopathic duodenal ulcers. Methods: A cross-sectional cohort study was conducted on 950 patients which were excluded from the analysis process duo to the concomitant presence of gastric ulcer, malignancy, Zollinger Ellison syndrome, Crohn's disease, esophageal varices, history of taking anti-Helicobacter pylori therapy, and history of taking NSAID or aspirin. Eventually, 647 subjects were enrolled for the analysis process. In this case, these subjects were divided into two groups: (I) Helicobacter pylori-positive ulcer group and (II) Helicobacter pylori-negative and non-NSAID (idiopathic) ulcer group. Results: The findings showed that 417 patients (64.5%) had duodenal ulcers induced by Helicobacter pylori, and 111 patients (17.1%) had Helicobacter pylori-negative and non-NSAID ulcers. The mean ages of patients in Helicobacter pylori-positive and idiopathic ulcer groups were 39±15 and 42±17, respectively. In this case, 33 patients (29.7%) with idiopathic ulcers and 56 patients (25.1%) with Helicobacter pylori-positive ulcers had upper gastrointestinal bleeding. Also, 22 patients (21%) with idiopathic ulcers and 31 patients (16.5%) with Helicobacter pylori-positive ulcers had multiple duodenal ulcers. Conclusion: The present study demonstrated that the idiopathic ulcers included 17.1% of duodenal ulcers. Also, it was concluded that patients with idiopathic ulcers were predominantly male with an age range older than the other group. In addition, patients in this group had more ulcers.
RESUMEN
Background: Various factors, most notably the stone's features, determine the selection of an appropriate method to extract common bile duct (CBD) stones during endoscopic retrograde cholangiopancreatography. In this study, the efficacy and safety of endoscopic sphincterotomy with balloon dilation (ESBD) versus endoscopic sphincterotomy (EST) for CBD stone extraction with a diameter of 10 to 15 millimeters were compared. Methods: This retrospective cross-sectional study included 154 patients referred to the Rouhani Hospital in Babol, Iran, with CBD stones. Consensus sampling was used. Each individual's demographic information and findings from the procedure were entered into the SPSS software (v. 26). A level of less than 0.05 was considered statistically significant. Results: A total of 154 patients were included in the study, of which 81 (52.6%) were in the EST, and 73 (47.4%) were in the ESBD group. Complete stones removal rate was higher in the ESBD versus the EST group (79.5% versus 46.9%, P<0.001). No significant differences were observed between the two methods' overall side effects rate (P = 0.469). Conclusion: For the complete extraction of CBD stones larger than 10 millimeters, the ESBD method outperforms the EST method.
RESUMEN
Helicobacter pylori as a common gastrointestinal (GI) pathogen must possess certain virulence characteristics to colonize the stomach, evade host immune responses, and subsequently induce GI diseases. This research aimed to investigate the expression level of two important genes, the sialic acid-binding adherence (SabA) and the blood group antigen-binding adhesion (BabA) in H. pylori strains isolated from adult patients living in the northern part of Iran, and their association with peptic ulcer disease (PUD) and gastric cancer (GC). This cross-sectional study was carried out on adult patients referring to the GI clinic of the hospitals affiliated to Babol University of Medical Sciences, Iran. New cases diagnosed with gastritis, peptic ulcer or gastric cancer were included. Endoscopic-guided gastric biopsies were examined and H. pylori positive colonies were analyzed to determine the expression of babA and sabA genes, utilizing specific primers and the SYBR Green dye. Among 175 patients with mean age of 51.6±15.6 years, 101 (57.7%) of the individuals tested positive for H. pylori infection. Statistical analysis revealed a significant correlation between sabA (P=0.003) and babA (P=0.002) gene expression and development of PUD and GC. Smoking (P=0.052), gender (P=0.004) and positive babA gene expression (P=0.009) had the greatest association with occurrence of PUD or GC in H. pylori positive patients. In summary, the presence of the sabA gene in people infected with H. pylori increased the risk of GC compared to gastritis, while, the presence of the babA gene was significantly increased in gastric ulcer patients. Considering the diversity of H. pylori isolates and the varying results observed in different geographical regions, further comprehensive studies are required to evaluate the function of these genes in H. pylori pathogenesis and their relationship with clinical outcomes.
RESUMEN
Background: Celiac disease is an autoimmune disorder resulting from gluten consumption in genetically predisposed individuals. The present study investigated the epidemiological, endoscopic, and clinicopathological features of patients with celiac disease in the southern littoral of the Caspian Sea. Methods: 140 patients with celiac disease were interviewed and examined regarding demographic characteristics, clinical symptoms, and serologic, endoscopic, and pathological findings. Results: 44 (31.4%) of the patients were male and 68.6% were female. The mean age of the patients at diagnosis was 27.13±13.4 years (ranging from 2 to 60 years). The most common gastrointestinal (GI) symptoms were bloating (47.8%), abdominal pain (47.1%) and diarrhea (30.7%), respectively. Also, 17 (12.1%) patients did not complain of any GI symptoms.18 (12.8%) patients had aphthous stomatitis, 10.7% had dermatitis herpetiformis, 3.6% suffered from itching without a rash, two (1.4%) mentioned psoriasis and one (0.7%) had lichen planus. 19 (19.7%) of the female patients complained of menstrual bleeding disorders, 4% mentioned infertility, and 2% experienced primary amenorrhea. The most common comorbid condition was hypothyroidism in 16 (11.4%) patients. The most common endoscopic finding was duodenal scalloping (37.25%). In addition, 7.8% of the patients had a normal endoscopic appearance. 43 (30.7%) patients were classified as Marsh IIIC, 25.7% Marsh IIIB, 17.8% Marsh IIIA, 12.8% Marsh II and 12.8% were classified as Marsh I. Conclusion: Since celiac disease can present with non-GI manifestations and the majority of our patients had Marsh III classification, it seems that celiac disease must be considered as a routine screening test in GI clinics, and also, it should be kept in mind as a differential diagnosis in other specialty fields.
RESUMEN
Background: The present study aimed to investigate the one-year prevalence of SARS-CoV-2, common comorbidities and demographic information among negative- and positive rRT-PCR in health care workers (HCW), hospitalized and outpatients. Also, the association between SARS-CoV-2 cycle threshold (Ct) and the outcomes of patients were analyzed in Babol, northern Iran. Methods: This large retrospective cross-sectional study was performed between March 2020 and March 2021. The records of 19232 hospitalized, outpatients and HCW suspected to COVID-19 were collected from teaching hospitals in the North of Iran. Results: Out of the 19232 suspected to COVID-19 patients, 7251 (37.7%) had a positive rRT-PCR result; 652 (9%), 4599 (63.4%) and 2000 (27.6%) of those were categorized as HCW, hospitalized and outpatients, respectively. Moreover, between the hospitalized and the outpatient group, 10.2 and 0.8% cases died, whereas no death cases were reported in the HCW. Furthermore, it seems that death rate was significantly different between the three groups of Ct value, the highest mortality in those with Ct between 21 and 30 (group B=7.6%) and the lowest in the group with the highest Ct (between 31 and 40 = 5.5%) (p<0.001). Conclusion: In summary, 37.7% of cases were positive for SARS-CoV-2; of which, 63.4, 27.6 and 9% were hospitalized, outpatients and HCW, respectively. With regard to the mortality rate in hospitalized patients and the significant association with Ct under 20 and 30, it seems that the early detection and the initial quantification of SARS-CoV-2 in the first week of the conflict and therapeutic considerations to reduce the relative load can reduce the mortality rate.
RESUMEN
BACKGROUND: Cap polyposis (CP) is a benign, non-malignant inflammatory disease that affects the rectum. It usually occurs during the 5th decade of life, but children could also be affected. Its specific pathology is unknown. Due to the clinical, endoscopic, and histologic similarities with other disorders such as inflammatory bowel disease, a thorough histologic evaluation is critical to avoid unnecessary interventions. This study presents a 15-year-old child with a previously reported case of solitary rectal ulcer (SRU) that developed into CP determined by colonoscopy and histologic findings. CASE PRESENTATION: A 15-year-old boy who was previously diagnosed with SRU presented to our office with rectal bleeding, mucoid discharge, and abdominal pain. Additional colonoscopy evaluation revealed multiple polyposes varying in size and shape limited to the rectum. Histologic examination revealed a characteristic cap of granulation tissue covering tortuous nondysplastic crypts in the inflamed stroma, indicating that SRU had transformed into CP. Based on the assessments, we planned to perform endoscopic mucosal resection of the lesions in multiple sessions. CONCLUSIONS: Despite the rarity of CP, the transformation from SRU may be one of its etiologies. Thus, thorough serial histologic evaluation is critical in children with rectal bleeding to avoid unnecessary or harmful interventions.

Introduction: COVID-19 virus pandemic has begun since 2020 and became one of the most important causes of mortalities. Accordingly, vaccination has found a vital role in control of COVID-19 virus. Despite many advantages of vaccines in controlling the virus spread and reducing the mortal rate, these benefits came at the expense of side effects which have not been fully explored nor should be ignored. One of the most serious side effects of vaccination, which has been reported recently, is liver injury. Case presentation: This study presents a case of hepatitis initiated by Sinopharm vaccine for COVID-19. A 62-year-old man presented with jaundice, weight loss and elevated liver enzymes three days after getting the second dose of COVID-19 vaccine. Microscopic sections showed hepatitis pattern of injury with both portal and lobular inflammation and marked eosinophils infiltration. Discussion: Several cases of hepatitis have been reported after COVID-19 vaccines, but almost all of them were diagnosed as autoimmune hepatitis, triggered by COVID-19 mRNA or viral vector vaccines but the present case is one of the first reported cases of hepatitis after Sinopharm vaccine, an inactivated virus COVID-19 vaccine. Spontaneous decrease in liver enzyme levels, without corticosteroids therapy, is against to the diagnosis of autoimmune hepatitis in other reported cases. Conclusion: Considering the microscopic findings, along with the negative serologic studies for viral and autoimmune hepatitis, and by ruling out of other causes of hepatitis like COVID-19 or other viral infections, a probable relation between liver injury and Sinopharm vaccine may be interpreted.
RESUMEN
BACKGROUND: Unlike some regions of the world where digestive system cancers are not considered as important health problems, these neoplasms are among the most common malignancies in the northern region of Iran. METHODS: This observational analytical study was carried out based on data collected by the Cancer Registration Center affiliated to the Vice Chancellery for Health of Babol University of Medical Sciences, North of Iran, during 2008-2017. Crude incidence rate (CR), and age-standardized incidence rate (ASR) have been calculated for different GI cancers, based on the primary involved site; and have been compared in different years, patients' age, gender and place of residence. RESULTS: Totally, 4332 records were related to digestive system cancers. Mean age of patients was 63.48±14.73 years; men (2743; 63.3%) were more affected than women (1589; 36.7%) (p<0.001). The most incident malignancies of digestive system were from stomach, colorectal and esophagus in men; and colorectal, stomach and esophagus in women, respectively. These three cancers accounted for 3725 (85.98%) of total GI malignancies. The mean age of patients in various types of GI cancers was statistically different (p<0.001). Age- standardized incidence rate showed different values in different years; from 521.40 (95% CI: 462.79-580.00) in year 2016 to 1834.33 (95% CI: 1637.36-2031.29) in year 2008. CONCLUSION: Gastric, esophageal and colorectal cancers were the most prevalent digestive system malignancies in Babol, North of Iran, and accounted for about 86% of all GI tract cancers. A considerable variation has been found in incident gastrointestinal cancers in different years.
RESUMEN
BACKGROUND: Eradication of Helicobacter pylori infection is challenging. We aimed to determine the optimal first-line H. pylori treatments at global and regional levels. METHODS: We searched Embase, PubMed, Cochrane CENTRAL, Web of Science, Scopus, WHO ICTRP, ClinicalTrials.gov, and ISRCTN registry, for randomized controlled trials published during 2011-2020. Utilizing a network meta-analysis in a Bayesian framework, success rates of 23 regimens were compared. The effect size was standardized risk ratio (RR) with 95% credible interval (CrI). Pooled eradication rate (ER) with 95% CrI was also reported for top combinations. The reference regimen was 7-day clarithromycin-based triple therapy. RESULTS: This review identified 121 trials comprising 34,759 participants. Globally, 14-day levofloxacin-based sequential therapy was the most efficient (RR: 1.43; 95% CrI, 1.26-1.59) with low certainty of evidence, followed by modified bismuth-containing quadruple therapy (proton pump inhibitor+bismuth compounds+clarithromycin+amoxicillin) for 10 days (RR: 1.35; 95% CrI, 1.22-1.48) and 14 days (RR: 1.27; 95% CrI, 1.12-1.42), and 14-day hybrid therapy (RR: 1.27; 95% CrI, 1.19-1.36). The corresponding ERs were 98.7% (95% CrI, 86.9-100.0), 93.2% (95% CrI, 84.2-100.0), 87.6% (95% CrI, 82.1-93.8), and 87.6% (95% CrI, 77.3-98.0), respectively. Continentally, the most effective combinations were: 10-day clarithromycin-based sequential therapy [(RR: 1.21; 95% CrI, 1.02-1.42), (ER: 89.5%, 95% CrI, 75.5-100.0)] for Africa, 14-day levofloxacin-based sequential therapy [(RR: 1.41; 95%CrI, 1.27-1.58), (ER: 98.7%, 95% CrI, 88.9-100.0)] for Asia, and 14-day clarithromycin-based triple therapy [(RR: 1.58; 95% CrI, 1.25-2.04), (ER: 94.8%; 95% CrI, 75.0-100.0)] for Europe. For Northern America, no sufficient data were found for network meta-analysis. In South America, none of the combinations were superior to the reference regimen. CONCLUSION: Although results of this network meta-analysis revealed optimal combinations for empiric therapy, the treatment preference would be based on the local pattern of antibacterial resistance, when the necessary information exists.

Background Folate is an important vitamin with protective effect against some human diseases. The aim of this study was to evaluate the relationship between serum folate levels, inflammatory markers and disease clinical activity in patients with inflammatory bowel disease (IBD). Methods The participants were classified into two groups in which 38 IBD patients and 38 healthy controls were studied. Disease clinical activities were evaluated by means of established score systems. Serum folate, homocysteine and C-reactive protein and ESR were measured. Obtained data were analyzed with proper statistical methods and P- value less than 0.05 was considered as statistical significant. Results The level of serum folate was significantly reduced in IBD patients with active disease compared to patients with clinical remission (p=0.043) and also healthy controls (p = 0.008). Moreover, there was a significant inverse correlation between serum folate levels and C-reactive protein in IBD patients (r = -0.563 p =0.001). Conclusion Serum folate levels is associated with inflammatory markers and disease clinical activity in IBD patients, therefore there is a possibility that disease clinical activity is reduced with adequate folate level.

PURPOSE: Colorectal cancer (CRC) is the second leading cause of cancer deaths. This screening aimed to determine the positivity of the fecal occult blood test (FOBT) and the results of colonoscopy among a medium-risk population in the northern regions of Iran. METHODS: This cross-sectional study was conducted in 2016 on 924 eligible samples from people over the age of 50. After completing the questionnaire, participants were referred to a laboratory for three immunochemical fecal occult blood tests (IFOBTs). If the result of at least one test was found to be positive, they were submitted to the state hospital for colonoscopy. Results were recorded according to the number of people with CRC, polyps, and other diseases. RESULTS: Among a total number of 897 (97.1%) cases, at least two acceptable samples were sent to the laboratory and in 229 (25.5%) cases, at least one case was IFOBT-positive. Finally, 118 (64.1%) cases were referred to the hospital for colonoscopy; among these, 5 colonoscopies were incomplete, while 113 had complete colonoscopies with 42 healthy subjects, 3 cases of cancer, 28 cases of polyps, and other diseases identified in the remaining patients. CONCLUSIONS: Based on the results, the prevalence of positive IFOBT, polyps, and cancer was high. The results of this study will play an important role in establishing a CRC screening program in the country. With reference to the status of the general population, the target group in the country should be reviewed and not limited to the first-degree relatives of patients.

BACKGROUND: The role of Helicobacter pylori (H. pylori) in inflammatory bowel disease is a controversial argument. The initial theory of this study was that Helicobacter is a risk factor for inflammatory bowel disease. In this study, we investigated the coincidence of H. pylori exposure and IBDs. METHODS: This case-control study has been done in Babol, teaching Hospitals; 60 newly diagnosed IBD cases without any Helicobacter eradicating treatment and 120 control patients without inflammatory bowel disease evidence in biopsy, investigated for H. pylori exposure by IgA and IgG ELISA tests. Clinical information, demographics and ELISA test results have been analyzed using SPSS.Version.18 (level of significance was less than 0.05). RESULTS: Mean age of case group was 42.27±13.64 years; in control group it was 45.52±13.83 years. There was a significant difference between the case and control groups in IgG study of the following subgroups: age under 30, females, males, urban, higher education level and BMI between 18.5 and 24.9 (p-value was respectively; 0.004, 0.014, 0.047, 0.002, 0.013, 0.003). On the basis of logistic regression; IBD was less common in females, patients with lower education and patients with positive result of IgG (p-value was respectively 0.002, 0.013, 0.010). CONCLUSION: As a result of this study, Helicobacter pylori exposure, may could play a protective role against inflammatory bowel disease.
RESUMEN
BACKGROUND: Helicobacter pylori (HP) infection is one of the hypothesized infectious etiologies of gastric cancer (GC) and other gastroduodenal diseases. It was suggested that other infectious agents, including oncogenic viruses, may increase the risk of gastroduodenal diseases. A number of reports regarding JC polyomavirus (JCPyV) have shown that JCPyV could be implicated in colorectal cancer and gastrointestinal carcinogenesis. OBJECTIVE: The current investigation aimed to investigate whether JCPyV could have any association with the pathogenesis of gastroduodenal diseases either alone or together with HP. METHODS: A total of 237 fresh or formalin-fixed and paraffin-embedded gastroduodenal samples were examined by quantitative real-time polymerase chain reaction targeting the JCPyV large tumor antigen (LTag) oncogene, and viral load was determined as viral copy number/cell. RESULTS: In total, 2 out of 237 samples (0.8%) were positive for JCPyV LTag DNA. One positive sample derived from diffuse-type gastric adenocarcinoma (6.8 × 10-3 copies/cell) and other JCPyV-positive sample obtained from a patient with gastritis (2.5 × 10-3 copies/cell) were recorded. Both JCPyV-positive samples were negative for HP infection. CONCLUSION: This study suggests no association between JCPyV infection and GC or other gastroduodenal diseases. The very low frequency of JCPyV LTag sequences in GC is an important aspect that weakens the hypothesis of the pathogenic role of JCPyV in gastric tumor induction.
RESUMEN
BACKGROUND: Striking prevalence of Helicobacter pylori infection has been convoluted with considerable resistance to various antibiotics worldwide. Although many eradication regimens have been introduced as the first-line therapies against H pylori, lack of appropriate multiple comparison studies makes hard to implement such results to the clinical practice. This project attempts to utilize a comprehensive network meta-analysis to pool the results of clinical trial comparing various first-line eradication therapies simultaneously in different continents. METHODS: We will include all randomized controlled trials assessing the first-line regimens for treatment of H pylori published in last 10 years. We will search the databases of PubMed, EMBASE, Scopus, Web of Science and Cochrane Central Register of Controlled Trials, International Standard Randomised Controlled Trial Number registry, World Health Organisation International Clinical Trials Registry Platform, and ClinicalTrials.gov for randomized controlled trials published since January 2009 without language limitation. The primary and secondary outcomes will be H pylori eradication rate and adverse events, respectively. Subgroup analyses will be conducted for different continents. Two reviewers will independently contribute in study selection and data extraction. For evaluating quality of studies, Cochrane Collaboration tool score will be used.

BACKGROUND: Colorectal cancer (CRC) is one of the most common types of gastrointestinal cancers. This study aimed to determine the demographic characteristics and their relationships with the results of the first screening program for CRC in people over 50 years old in northern Iran. METHODS: This cross-sectional study was conducted in 2016 on 924 eligible people over 50 years old. Initial screening was done by IFOBT and then colonoscopy was performed if the results were positive. The demographic characteristics of individuals including age, sex, place of residence, marital status, body mass index (BMI) and education level were investigated with the results of the colonoscopy and the test results. RESULTS: The mean age of participants was 59.38 years, and the participation of women (57.0%) and rural residents (54.2%) were higher in the screening program. According to the demographic variables, age was considered as a strong independent predictor variable, so that the prevalence of positive test results was more than 2 times higher in subjects older than 70 compared with subjects aged ≤60 (OR =2.05; 95% CI, 1.18-3.55, P=0.010). Also, the chance of positive test result in the age group ≤55 years old was 23%, with an increase of 64% in the age group above 75 years (P<0.001). Among the positive test subjects, 118 cases underwent colonoscopy. CONCLUSIONS: The prevalence of IFOBT positivity was increased with age. Therefore, given the aging population of the country, it is recommended to emphasize on the screening of older people in the general population.
