Objective: To study the nature of fatigue damage in modern tank cars using the results of multiple collision life tests. To show the need for life tests by making appropriate changes to design documentation and increasing the competitiveness of products due to the increase in service life. To conﬁrm the possibility of a longer service life of the wagons. To identify potentially hazardous areas in car’s structure, most susceptible to damage during operation. Methods: An experimental method was applied to assess the indicators of the cyclic durability on elements of the car’s structure by testing the resource in multiple collisions. Mathematical statistics were used to assess the test results and identify fatigue damage. Results: A comparative analysis was conducted on the design features of tested cars. The procedure for testing in impacts is also described. A statistical assessment of loading modes and accumulated fatigue damage is presented. Failures were experienced that impeded further testing. The results of the tests conﬁrmed an increase in the service life of the cars of up to 32 years. On the basis of the detected damage, the car structure zones most susceptible to damage in operation were statistically determined. Practical importance: The need to increase the service life of cars up to 32 years was conﬁrmed. The results of the tests carried out made it possible to make appropriate changes in the design documentation and to increase the competitiveness of cars produced by JSC Ruzkhimmash in the modern market. The accumulated experimental data can be used in the future design of tank cars giving improved operational characteristics compared to the existing rolling stock, including structural units subject to fatigue damage during operation.

Objective: To compare the possibilities of using mobile laser scanning (MLS) and aerial photography (AFS) from an unmanned aircraft system (UAS) and to make a survey from an integrated road laboratory when performing diagnostics of highways. Methods: For the analysis, a section of the regional road in the Kursk region was selected, on which the survey was carried out using considered methods. The main characteristics were identiﬁed when performing the diagnostics, their values were obtained on the basis of data from the integrated road laboratory, aerial photography with UAS, as well as ILS, and the accuracy of the results obtained, the compliance of the data with the requirements of regulatory documents were assessed. Results: Based on the work performed, the following conclusions were made: the determination of identiﬁed diagnostic parameters by the methods of ILS and APS with UAS is correct and aerial photography with UAS at the cost of equipment, the cost of shooting is the most proﬁtable when drawing up topographic road plans. It is noted that in terms of accuracy, the APS method meets the requirements for plans at a scale of 1:500, MLS – 1:1000. Practical importance: Not all indicators required for diagnostics can be obtained with APS with ALS and MLS, since they require specialized equipment and direct interaction with the road surface, however, the range of application of the selected methods can be signiﬁcantly expanded. Adhesion coefﬁcient is measured using an integrated mobile road laboratory, so it is not advisable to abandon it. It was noted that the equipment of the laboratory, depending on the cost, may be different

Objective: To analyze the impact of computer attacks on the performance quality of data transmission channels and channeling systems. It is also necessary to take into account the capabilities of an intruder to introduce malware into channeling systems when committing a computer attack. Methods: To determine the required design ratios, several options for setting various distribution functions characterizing the parameters used as input data and types of inbound streams have been considered, taking into account the parameters of the intruder’s computer attack model set by the values of the probability of successful attack. Mathematical modeling is carried out using the method of topological transformation of stochastic networks. The exponential, momentum and gamma distributions are considered as distribution functions of random variables. The solutions are presented for inbound streams corresponding to the Poisson, Weibull, and Pareto models. Results: The proposed approach makes it possible to assess the performance quality of data transmission channels in the context of computer attacks. These assessments make it possible to analyze the state and develop guidelines for improving the performance quality of communication channels against the destructive information impact of the intruder. Various variants of the functions of random variables distribution and various types of the inbound stream were used for modeling, making it possible to compare them, as well as to assess the possibility of using them in channels that provide users with different services. Practical importance: The modeling results can be used to build communication management decision support systems, as well as to detect attempts of unauthorized access to the telecommunications resource of transportation management systems. The proposed approach can be applied in the development of threat models to describe the capabilities of the intruder (the ‘Intruder Model’).

Vacunación contra Newcastle y Peste Porcina Clásica entre pequeños y medianos productores y su relación con brotes confirmados de enfermedad
Authors: Planas Micaela , Falcón Néstor
Published: August 2021

El objetivo del estudio fue evaluar los alcances de vacunación contra la enfermedad de Newcastle (ENC) y Peste Porcina Clásica (PPC) entre pequeños y medianos productores peruanos. Se recuperaron resultados de la Encuesta Nacional Agropecuaria del año 2018 para determinar su relación con los brotes confirmados de enfermedad publicados en los reportes epidemiológicos del Servicio Nacional de Sanidad Agraria (SENASA) para los años 2016 - 2018. Los resultados obtenidos desde ambas fuentes de información fueron resumidos mediante estadística descriptiva utilizando frecuencias absolutas y relativas. La comparación entre la presencia de brotes de PPC y NC reportadas por el SENASA en los departamentos y las prácticas de vacunación en al menos el 70% de los encuestados, se realizó utilizando la prueba exacta de Fischer. El estudio recuperó 1518 y 2774 encuestas de pequeños y medianos productores de aves y cerdos respectivamente. El 94.9% (1441) de los criadores de aves afirmaron haber vacunado a sus animales contra la ENC, mientras que el 76.7% (2127) afirmó haber vacunado a sus animales contra la PPC. Los departamentos con la mayor cantidad de brotes de ENC fueron Ica  y Cajamarca, que sumaron en conjunto 44.8% (13/29) del total. En caso de PPC, los departamentos con la mayor cantidad de brotes fueron Cajamarca, Lima y Lambayeque que sumaron el 53% (79/149) del total de brotes, para el periodo de estudio. No se encontró asociación entre la presentación de brotes para ENC y PPC con la práctica de vacunación. Se concluye que existen departamentos con brotes periódicos de ENC y PPC en los que pequeños y medianos productores no participan en las campañas de vacunación organizadas por el SENASA, lo que representa un riesgo para la perpetuación de reservorios de dichas enfermedades, favoreciendo la persistencia de los virus en estas poblaciones animales.

Contemporary Competition: Process or Result?
Authors: Rozanova N.
Published: August 2021

Digital economy has significantly changed business reality. The radical transformations are ubiquitous. New patterns feature economic behaviour of market participants, their interactions, their business models and their market activities. What about competition? What forms of competitive conduct have lost importance in contemporary digital economy? And what are the newest strategies that enhance competitiveness of the firms? Which digital business practices could limit competition? And which of them could stimulate business rivalry? Digitalization has changed many, in not all, of our traditional conceptual visions in the area of competition, market, market power, relevant market actors. The nature of competition itself is under scrupulous investigation. What conclusions could we draw from current theoretical and empirical analyses of competition mechanism? First of all, we deal with new forms of competition. The old Schumpeterian question – whether competition is a creative innovative destruction or it leads only to unfair elimination of competitors from the market – has arisen again nowadays. Online competition has two radically different outcomes. On the one hand, lower transaction costs, more possibilities to compare prices and assortment, expanding markets beyond geographical limits, low entry barriers reinforce rivalry. On the other hand, online activity of the firms can mitigate competitive pressure though new forms of product differentiation and usage of phantom strategies, phantom products, phantom plans. In order to increase their overall competitiveness, firms have elaborated an O2O (online-to-offline) business model that is allowed to utilize virtual and actual activity at the same time. Restaurant business, cosmetic industry, taxi deals are examples of its successful implementation. Is more competition better for consumers? This concept has been considered doubtful. Digital competitive pressure has led to a novel format of product differentiation, that is, targeted product design. Unlike traditional view in line with Salop circular model, contemporary firms choose product strategies that target as little individuals as possible. The less the circle of potential clients is, the less their price elasticity would be, and the weaker price rivalry might become. Traditional concept views competition as a Markov stochastic process. Contemporary analyses demonstrate more complicated nature of competitive mechanism. Online and offline innovations transform competition into non-linear process with “humps and jumps”, the outcomes of which are not always in the interests of consumers’ welfare.
Goals and Objectives of the State Policy of the Republic of Korea in the Arctic

Published: August 2021

The article compares the provisions of normative documents that determine the Arctic policy of Korea and the results of a survey by Korean experts dealing with Arctic issues. The presented study examines the issues of transforming the priorities of the ROK state policy in the Arctic and promising areas of Seoul’s activity in the Arctic region. An analysis of the main regulatory documents that determine the priorities of the Republic of Korea in the Arctic (the Arctic Policy Basic Plan for 2013–2017 and the Arctic Development Basic Plan for 2018–2022) demonstrates the growing importance of economic cooperation in the Arctic as a priority for Korean policy. The results of the expert survey conducted as part of the study demonstrate that the Korean expert community considers environmental protection and response to climate change a paramount for the country’s policy in the Arctic region. According to the study, the experts have chosen the following most important tasks in the Arctic: “responding to climate change and forecasting climate change”; “protection of the marine environment and biological resources”; “conservation of ecosystems”; “the introduction and development of polar scientific research”; “expansion of polar research and monitoring infrastructure”. The survey results indicate that the key direction of the Arctic policy for the Republic of Korea, is the development of international relations within the framework of the Arctic Council, the main subject of which is scientific research in the field of climate and ecology. Thus, despite the priorities formulated in the General Plan for the Development of Arctic Activities for 2018–2022, Arctic experts consider the establishment of international partnerships to be a more important task than the participation of Korean business in Arctic projects and the creation of Arctic infrastructure.

Christian Churches and the Antiidentist Revolution
Authors: Lunkin R. , Filatov S.
Published: August 2021

The article analyzes the ideological contradictions of liberal democracy, or neoliberalism (antiidentism), and traditionalism (identism) on the example of Christian churches. Antiindentism considers traditional religiosity to be hostile: it should be reformed to conform to neoliberal values, and it should be banished from public space. At the same time, antiidentism does not want to eliminate religion, because it is one of the identities that have to be redone like other human identites. The article examines anti-Christian movements (like the “Black Lives Matter”) as well as conservative and liberal movements within various confessions. The authors emphasize that the antiidentist demands are based on the Christian values of respect for any person, for women and men, regardless of anything, for humane methods of raising children, mercy for any categories of people, regardless of their sexual orientation, etc. On the other hand, the demands of antiidentists go far beyond Christian principles and even common sense (not to quote inconvenient passages of the Bible, to change the rules of church life and the appointment of clergy). The article proposes a classification of confessions by direction and by territorial feature, depending on specifics of divisions based on the attitude to antiidentism (American Churches, the Catholic Church, Lutherans and Anglicans as well as diversity of Orthodox churches that are also touched by the antiidentist wave). The authors conclude that the Christian churches, despite the existence of liberal factions, are primarily a traditionalist force in modern politics. Because of fundamental ideological differences, the consolidation of diverse Christian forces is a difficult task. However, there is some progress in this direction. Evangelicals, traditional Catholics, who make up the majority of the Catholic Church, as well as the majority of Orthodox Christians, are a serious political and, what perhaps more important, ideological force.
Sexual Abuse vs Sexual Freedom? A Legal Approach to the Age of Sexual Consent in Adolescents in Spanish-Speaking Countries
Authors: Parra-Barrera Sandra M. , Sánchez-Fuentes María del Mar , Fuertes-Iglesias Carlos , Boldova Miguel Ángel
Published: August 2021

Child and adolescent sexual abuse (CSA) is an international public health problem. Despite the importance of the CSA, there is no consensus definition, and the lack of consensus is related to difficulties in conducting prevalence studies, as well as research in other areas. To establish a consensual definition, legal aspects such as the age of sexual consent and the difference in age or power between victim and aggressor, aspects related to sexual freedom and sexual indemnity must be considered. Therefore, the main goal of this research was to analyze the age of sexual consent in the legal systems of Spanish-speaking countries and to examine whether the Romeo and Juliet clause is established. To achieve the proposed aims, we employed the legal interpretation method, and we analyzed the current Criminal Codes of the 21 Spanish-speaking countries. From the results, it is found that the age of sexual consent varies between countries, establishing valid sexual consent between 13 and 18 years. In addition, only six countries have the Romeo and Juliet clause that protects sexual freedom in adolescents. Finally, we discussed the lack of consensus on the age of sexual consent and the limitations presented by the Romeo and Juliet clause.

Materials based on Mg2+-containing phosphates are gaining great relevance in the field of bone tissue repair via regenerative medicine methods. Magnesium ions, together with condensed phosphate ions, play a significant role in the process of bone remodeling, affecting the early stage of bone regeneration through active participation in the process of osteosynthesis. Here we pro-vide a comprehensive overview of the usage of biomaterials based on magnesium phosphate and magnesium calcium phosphate in bone reconstruction. The role of magnesium ions in angiogene-sis, an important process associated with osteogenesis, is considered. Finally, the biological properties of magnesium phosphates for bone regeneration are summarized. They show promis-ing results in terms of use as bone replacement material.

DL provides ground for technology development for computer-aided diagnosis and segmentation in radiology and radiation oncology. Amongst the anatomical locations where recent auto-segmentation algorithms have been employed, the pelvis remains one of the most challenging due to large intra- and inter-patient soft-tissue variabilities. This review provides a comprehensive and clinically-oriented overview of DL-based segmentation studies for bladder, prostate, cervical and rectal cancers, highlighting the key findings, challenges and limitations.
Covalent 18F-Radiotracers for SNAPTag: a New Toolbox for Reporter Gene Imaging
Authors: Stotz Sophie , Bowden Gregory D. , Cotton Jonathan M. , Pichler Bernd J. , Maurer Andreas
Published: August 2021

There is a need for versatile in vivo nuclear imaging reporter systems to foster preclinical and clinical research. We explore the applicability of the SNAPTag and novel radiolabeled small-molecule ligands as a versatile reporter gene system for in vivo nuclear imaging. SNAPTag is a high-affinity protein tag used in a variety of biochemical research areas and based on the suicide DNA repair enzyme O6-methylguanine methyl transferase (MGMT). Its ligands are well suited for reporter gene imaging as the benzyl guanine core scaffold can be derivatized with fluorescent or radiolabeled moieties for various applications. Three guanine-based SNAPTag ligands ([18F]FBBG, [18F]pFBG and [18F]mFBG) were synthesized in high yields and were (radio)chemically characterized. HEK293 cells were engineered to express the SNAPTag on the cell surface and served as cell model to assess target affinity by radiotracer uptake assays, Western blotting and SDS-PAGE autoradiography. A subcutaneous HEK293-SNAPTag xenograft model in immunodeficient mice was used for in vivo evaluation of [18F]FBBG amd [18F]pFBG while the biodistribution of [18F]mFBG was characterized in naïve animals. The results were validated by ex vivo biodistribution studies and immunofluorescence staining of the xenografts. All three radiotracers were produced in high radiochemical purity, molar activity and good yields. Western blot analysis revealed successful SNAPTag expression by the transfected HEK293 cells. In vitro testing revealed high target affinity of all three tracers with an up to 191-fold higher signal in the HEK293-SNAPTag cells compared to untransfected cells. This was further supported by a prominent radioactive protein band at the expected size in the SDS-PAGE autoradiograph of cells incubated with [18F]FBBG or [18F]pFBG. The in vivo studies demonstrated high uptake in HEK293-SNAP xenografts compared to HEK293 xenografts with excellent tumor-to-muscle ratios (7.5 ± 4.2 for [18F]FBBG and 10.6 ± 6.2 for [18F]pFBG). In contrast to [18F]pFBG and its chemical analogue [18F]mFBG, [18F]FBBG showed no signs of unspecific bone uptake and defluorination in vivo. Radiolabeled SNAPTag ligands bear great potential for clinical applications such as in vivo tracking of cell populations, antibody fragments and targeted radiotherapy. With excellent target affinity, good stability, and low non-specific binding, [18F]FBBG is a highly promising candidate for further preclinical evaluation.
FinTech in Latvia: Status Quo, Current Developments and Challenges Ahead
Authors: Rupeika-Apoga Ramona , Wendt Stefan
Published: August 2021

FinTech has been in the focus of the discussion for quite some time. However, the market share of FinTech companies is still relatively small in compared to more traditional financial services. The purpose of this paper is to analyse the status quo, current developments and challenges ahead for the Latvian FinTech sector. We combine three analyses: the political and legal, the economic, the social and the technological environment (PEST) analysis, an analysis of the size and performance of FinTech companies during the last 10 years, and a survey among FinTech companies. We find that the current status of regulation is one of the main obstacles to FinTech development, because it does not sufficiently consider FinTech-specific aspects. Problems in attracting skilled workforce, and an environment that is not very supportive of new developments in finance are further challenges and might explain at least part of the growth and performance difficulties. A revision, modernization and harmonization of regulation is essential to create a level playing field for all market participants: FinTech companies, traditional financial service providers and those originally traditional players that are integrating FinTech solutions in their business model. Further efforts are also required to foster the Latvia’s attractiveness for skilled workforce. We hope that this study helps increase the visibility of Latvian FinTech and contributes to the development of the new Latvian FinTech strategy.

LA TEORÍA DE LA COMPARACIÓN SOCIAL COMO PROMOTORA DE LAS CONDUCTAS DE SALUD: UNA APROXIMACIÓN TEÓRICA
Authors: García del Castillo Rodríguez Jose Antonio , García-Castillo Fernando , Acevedo Dias Paulo César , García del Castillo-López Álvaro
Published: August 2021

La salud es uno de los principales activos para las personas en relación con el estado de bienestar y la calidad de vida. Desde la Psicología de la Salud se han desarrollado teorías y modelos eficaces para amortiguar los factores de riesgo de salud y potenciar la conducta de salud. Las acciones de control de las enfermedades no transmisibles pasan necesariamente por medidas preventivas. Es imprescindible actuar de forma rápida y eficaz para que las consecuencias de mortalidad se minimicen al máximo y para ello es necesario poner en marcha programas de educación para la salud e intervenciones psicosociales que potencien las conductas de salud. Se propone un postulado teórico desde la teoría de la comparación social para el aprendizaje y/o la modificación de conductas de salud y estilos de vida sanos. Entre las dimensiones de la comparación social revisadas, podemos destacar aquellas que parten de las motivaciones de auto mejora como contraste descendente y el deseo de superación como identificación ascendente para explicar teóricamente la promoción de conductas de salud.

Published: August 2021

A pleuroperitoneal communication is a serious complication for patients undergoing continuous ambulatory peritoneal dialysis (CAPD). Video-assisted thoracoscopic surgery is performed using indocyanine green adsorbed to human serum albumin fluorescence to identify the communication because human serum albumin reinforces fluorescence images. A patient diagnosed with a pleuroperitoneal communication was referred to our department and underwent surgery. To detect the communication, a dialysate mixture that contained indocyanine green and human serum albumin was injected from the CAPD catheter. Real-time fluorescence images were able to clearly show a bleb-like lesion with a near-infrared spectroscopy camera, and the site was repaired. The patient had no recurrence at one-year follow-up. This method might be good method for pleuroperitoneal communication surgery.

The current research examined the magnitude of genotype by environment interaction (G x E) and evaluated the adaptability and stability of maize genotypes for grain yield in Ethiopia's transitional highland agroecology using an additive main effects and multiplicative interaction (AMMI) model. The study's goals were to first assess the yield output and stability of maize genotypes in Ethiopia's transitional highlands, and then to investigate the effect of genotype- environment interaction on genotype yield. During the main season of 2017/2018, thirteen advanced maize genotypes which was selected from different observation trials with two commercial check hybrids were evaluated at five representative locations for agroecology. The experiment was set up using an alpha lattice (3*5) with three replications and two rows per plot. AMMI showed highly significant(P < 0.001) variation of grain yield was observed due to the effect of genotype (G), Environment(E) and their interaction (G x E). In fact, all genotypes evaluated in representative locations for this agroecology had higher grain yield advantages than the best commercial check except one genotype. Overall, this study discovered the possibility of fast releasing and overtake of new maize hybrids for transitional high land agroecology of Ethiopia to exploits availability maize germplasm to maximize production. The best candidate genotype, MABK181261 is a stable and high-yielding product. It is recommended for release as a commercial hybrid alternative after national variety verification trial in a high land transitional agroecology of Ethiopia. In addition, the parental lines of this genotypes can be used to enhance germplasm of opposite heterotic group in maize breeding for East Africa.

Published: August 2021

We propose a detailed study of an on-chip optical modulator using a non-conventional silicon-based platform. This platform is based on the optimum design of ultra-thin silicon on insulator (SOI) waveguide. This platform is characterized by low field confinement inside the core waveguide and high sensitivity to the cladding index. Accordingly, it lends itself to a wide range of applications, such as sensing and optical modulation. By employing this waveguide into the Mach-Zehnder interferometer (MZI) configuration, an efficient optical modulator is reported using an organic polymer as an active material for the electro-optic effect. An extinction ratio of more than 20 dB is achieved with energy per bit of 13.21 fJ/bit for 0.5 V applied voltage. This studied platform shows promising and adequate performance for modulation applications. It is cheap and easy to fabricate.

This study aimed to investigate the effect of beta-glucan in rainbow trout’s diet on survival, growth performance, hematological, immunity and biochemical parameters. Rainbow trout (Oncorhynchus mykiss) with an average weight of 6.35 ± 0.09 were stocked in 30 fiberglass tanks with a volume of 200 liters. Four treatments including: control group (0%), 0.5, 1 and 2% of beta-glucan were considered for 8 weeks. The results showed that the survival and growth performance of rainbow trout in the control group were at the lowest level and showed a significant difference with other treatments. The highest percentage of hematocrit (47.9%), white blood cell count, neutrophil percentage (35.2%) was observed in the treatment with 2% beta-glucan. Also, the highest lysosomal activity (59.7 units’ mL− 1, IgM (54.7 mg dL− 1), C3 and C4 was obtained in 2% beta-glucan treatment. Biochemical parameters showed improvement in treatments fed with 1 and 2% beta-glucan. In general, the present study showed that 2% beta-glucan in the diet of rainbow trout improves growth performance, survival, hematological, immunity and biochemical parameters.

BackgroundBased on the Developmental Origins of Health and Disease, adverse intrauterine environment – reflected by low birth weight (LBW) and prematurity – may induce fetal programming that favors kidney dysfunction in adulthood. We examined the association of LBW and prematurity with blood pressure (BP) and kidney function markers in non-diabetic middle-aged adults without kidney disease from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). MethodsA cross-sectional analysis of 768 subjects aged 35-54 years was conducted. Comparisons were performed according to birth weight: LBW (<2.5 kg) or normal birth weight (NBW) (2.5-4.0 kg). Associations of LBW and prematurity with BP levels and kidney function markers (glomerular filtration rate - eGFR, albumin-creatinine ratio - ACR and serum cystatin C) were tested by multiple linear regression using adjustments based on Directed Acyclic Graphs. Propensity score matching was applied to control imbalances. ResultsMean age of participants was 45.5 ± 4.6 years and 56.8% were female; 64 (8.3%) participants reported LBW and 39 (5.0%) prematurity. The LBW group had higher systolic (p = 0.015) and diastolic BP (p = 0.014) and ACR values (p = 0.031) and lower eGFR (p = 0.015) than the NBW group, but no group difference for serum cystatin C was found. The preterm group had higher mean levels of systolic and diastolic BP, but no difference in kidney function markers was evident. In a regression model adjusted for sex, skin color and family history of hypertension, both systolic and diastolic BP levels were associated with LBW, but this association disappeared after adding prematurity, which remained associated with BP (p = 0.017). Having applied propensity score matching, LBW was associated with ACR values (p=0.003), but not with eGFR or BP levels. ConclusionThe study findings of independent associations of prematurity with higher BP levels, and of LBW with markers of kidney function, in adulthood support that early life events predict risk for hypertension and kidney dysfunction in adulthood. The study design precluded the inferring of causality, and prospective studies are needed to further investigate the hypothesis raised.

Purpose:Investigate whether a head and neck cancer specific needs assessment tool integrated in nursing rehabilitation consultations early in the post-surgical period would improve quality of life and symptom burden in patients surgically treated. Further, to assess the feasibility of carrying out needs assessments during consultations. Methods:92 surgically treated head and neck cancer patients at the Department of Otolaryngology, Head and Neck Surgery and Audiology, Copenhagen University Hospital, Denmark were enrolled. A two-arm randomized controlled trial design was used. Both arms received nursing rehabilitation consultations before discharge, approximately two weeks and two months post-operative. Patients in the intervention group had their needs assessed using an assessment tool.Primary outcome was quality of life. Secondary outcomes were symptom burden and referrals for multi-disciplinary rehabilitation follow-up. Results:No significant differences were found in quality of life or symptom burden. However, notable more patients in the intervention group were referred for rehabilitation. Conclusion:The intervention suggests that important needs were identified and addressed, especially emotional and existential needs, which were accommodated through referrals and professional advice. Nursing rehabilitation consultations using a needs assessment instrument may ensure that patient preferences and priorities are incorporated in their care.

Background/Aims: Gastric polyps (GPs) are usually asymptomatic lesions of the upper gastrointestinal tract observed in 1-3% of esophagogastroduodenoscopies (EGD). The majority of polyps are benign. The aim of this study was to precise the frequency of different types of gastric polyps in our population, and to analyze their possible association with other factors.Materials and Methods: A total of 18496 consecutive patients undergoing EGD over a ten-year period (between 2007 and 2018) in a tertiary hospital were retrospectively reviewed. Eighty-six patients diagnosed with gastric polyps were analysed. Demographics, medical history of the patients, and indication for gastroscopy were collected. Morphological, histological characteristics of polyps, and therapeutic management data were also collected.Results: GPs were found in 86 out of 18496 (0.46%) reviewed EGD, corresponding to a total of 141 polyps. There were 64 female (74.4%) and 22 male patients (25.6%) with a sex ratio (M/F) of 0.34. The average age was 58.1 years. One hundred and forty one polyps were included, and histopathology was obtained on 127 GPs. The most common location was the fundus (59.6%) and 48.9% were smaller than 5 mm. The polyp was unique in 75.6% of cases. According to Paris classification, 80% of the polyps were sessile (Is). Hyperplastic polyps were the most common (55.9%) were hyperplastic polyps, followed by sporadic fundic gland polyps in 23 patients (18.1%), 7 (5.5%) were adenomas, and 4 (3.1%) were neuroendocrine tumors type 1. The following factors were associated with hyperplastic polyps: anemia (p= 0.022), single polyp (p= 0.025) and size ≥ 5mm (p= 0.048). Comparing hyperplastic polyps biopsies to resected polyps, no difference was found in the evolutionary profile of the 2 groups. A size less than 10 mm (p=0.013) was associated with fundic gland polyps. Sixty polyps (47.2%) were treated by cold forceps, 19 (15%) treated by a mucosal resection and 15 (11.8%) with diathermic snare. Five procedural bleeding incidents were observed (3.9%). Only the use of anticoagulant treatment was associated with a high bleeding risk (p= 0.005). The comparative histological study between specimens of biopsied GPs and endoscopic polypectomy led to an overall agreement of 95.3%.Conclusion: In our study, the GPs frequency was 0.36%. Hyperplastic polyps and fundic gland are the most common gastric polyps in our country. The high frequency of Helicobacter pylori infection in our patients and in our area may explain the high frequency of HP.
