Differences in Kaizen implementation between countries and industry types in multinational supply chain
Authors: Spasojević-Brkić Vesna , Tomić Branislav , Perišić Martina , Janev Nemanja
Published: May 2023

Previous research shows that Kaizen's benefits are multiple and evident, but its practices in the supply chain have been sufficiently examined now. Conversely, we are witnessing numerous issues in contemporary global supply networks. In this survey, after conducting a literature review, three research questions regarding Kaizen modes of usage were formulated and tested on the sample of 195 enterprises that are part of the global supply chain, located in 31 countries, and active in two different types of industries - aircraft, and transportation. A combined approach containing descriptive statistics, reliability, factor analysis, and statistical hypothesis testing by Kruskal-Wallis one-way ANOVA and Mann-Whitney U tests were used. Results show significant differences between Kaizen practices applied in countries such as Italy, the United Kingdom, Canada, the USA, Japan, and China, where national and corporate cultures differ. Kaizen implementation significantly differs between companies operating in the aircraft and transportation sectors, which is unsurprising since aircraft industry has a higher formalization level. The goal to determine the differences in Kaizen practices around the globe was fulfilled since statistically significant differences indicate the importance of the contextual factors and connect adverse and Kaizen events.
Numerical analysis of stagger Supersonic biplane at off-design condition with trailing edge flap
Authors: Patidar Vijay , Joshi Sudhir
Published: May 2023

Supersonic biplanes can achieve low-boom and low-drag supersonic flights. In the present study, aerodynamic analysis of a two-dimensional stagger Bussmann biplane (staggered upper element by 0.5c) at zero degrees angle of attack with trailing edge flap was investigated with the help of computational fluid dynamics (CFD) tools. Due to the wave cancellation effect, the Busemann biplane delivers a positive drag reduction at design supersonic Mach values. However, when operating outside of its intended parameters, it performs worse, and the wave cancellation effect has no beneficial effects on reducing drag. Another issue with the Busemann biplane is flow chocking, which produces a potent bow shock wave in front of the aircraft. This paper attempts to address low aerodynamics efficiency problems during take-off through numerical simulation of a staggered Busemann biplane with trailing edge flaps at zero degrees angle of attack. It was confirmed that the staggered biplane airfoil with flap has better aerodynamic performance during take-off at lower subsonic free stream Mach numbers. In 2D wings, the effect of flow chocking and hysteresis as starting problems, which arise when the biplanes accelerate from low Mach numbers, is reduced by using the suitable dimension and angle of rotation of the flap, and the flap is effective in settling these issues.
Iran and Serbia: Difference that through dialogue turns into cooperation and friendship
Authors: Hassan Por
Published: May 2023

Iran's approach in the diplomatic relations with Serbia is long-lasting and of strategic character, based on the respect for mutual specifics, but also on firm understanding and need for even stronger cooperation. The long history of friendship has been shaped in the fires of large wars and crises for more than a century, with intensive diplomatic relations lasting for 85 years. The absence of unresolved problems in mutual relations indicates the quality of mutually proper cooperation, the priority of which is its deepening and directing from the sphere of politics to the fields of economy, science, education, culture and sport. The principled position in defending the attitudes of international politics and independence has further strengthened the friendship between the two countries.
Geriatric nurse in Russia today: Is the role determined?
Authors: Tsutsunava M.R. , Aristidova S.N.
Published: May 2023

The role of the nurse in geriatrics has been discussed for more than fifty years. As early as 1965, Doreen Norton, a well-known nursing theorist, wrote that no nurse in the world should start their career without a background in geriatrics that should be in the training structure. In Russia, currently there is a significant lack of qualified nursing staff in the field of geriatric care. Besides, there is still no such specialty as geriatric nurse. The aim is to consider the degree of definition and understanding of the role of the geriatric nurse in addressing the challenges associated with the aging of the population and the expansion of the group of older people with increased demands on social and medical services Methods: Analysis of the scientific papers for the period from 2015 to 2020 published on the CyberLeninka website. CyberLeninka is the scientific electronic libraries based on the Open Science paradigm, aiming at, in particular, popularization of science and scientific activities. Results: Cyberleninka revealed 14 articles met the criteria of inclusion in to the paper by titles. By content there was included 7 articles. In Russia, "geriatric nurse" means activity profile, not a specialty. There is no any special professional training courses in geriatrics, nurses mainly learn from the conferences on geriatrics in terms of the nursing sections or schools provided by NCO. Nursing beds are being run by nurses qualified as general practitioners. There is still evidence of misunderstanding of the geriatric nurses' role, nursing training in geriatrics at the college level is reported to be poor. Conclusions: Despite a number of the arguments supporting the importance of the geriatric nurse role and the need for its development in Russia, this issue remains undeveloped. It remains unclear why after having run 26-year history of Geriatrics in St.Petersburg geriatric nursing as a specialty has not been introduced officially and is waiting for being acknowledged.

Published: May 2023

One of the most effective ways for the future design, production, analysis and optimization of new processes, involving phase change of materials, is the development of highly sensitive quantitative methods based on the detection of temperature changes during the solidification process and the correlation of these changes with changes in the treated material. In this work, the secondary Al-8wt%Si3wt%Cu alloy was formed from the liquid state under free cooling conditions. Characteristic transformation temperatures were identified and a method for monitoring the amount of solid phase during the solidification process was formalized. From the recorded cooling curve, the values of the first derivative were determined and the corresponding reference curve was formed. The area between the first derivative of the cooling curve and the reference curve was used to assess the amount of solidified part of the material during the solidification process. The obtained results showed that the proposed method is effective in obtaining data of the fraction solid at every moment of the solidifcation process, as well as that it can be further used to detect the number of phases and microconstituents in the formed structure, as well as an experimental examination of the latent heat of solidification of new materials. The method of monitoring the amount of solid phase, formed under free cooling conditions, does not require specific preparation of samples or complex laboratory equipment, and accordingly, in practical application it effectively replaces standard methods for detecting thermophysical properties of materials, such as differential thermal analysis or differential scanning calorimetry.

Sustainable city logistics concepts: Elements and conceptualization
Authors: Kovač Milovan , Tadić Snežana , Krstić Mladen
Published: May 2023

Defining and the application of sustainable city logistics concepts is a prerequisite for achieving sustainability in urban areas. The scientific literature is abundant with research that highlights individual technologies, initiatives, measures and approaches as indispensable elements of sustainable concepts. Although a relatively large set of city logistics concepts is analyzed in the literature, there is no generally accepted set of guidelines for defining sustainable city logistics concepts. This article tries to fill that literature gap. The main contribution of this article is, on basis of the review of relevant literature in the field, to demonstrate how potentially sustainable city logistics concepts could be conceptualized by combining different building elements (technologies, initiatives, measures, and approaches).

El despoblado de Mazmullar: una nueva interpretación
Authors: Ortega López David
Published: May 2023

La investigación sobre el yacimiento de Mazmullar se quedó paralizada en los años 90 después de finalizar la última actividad arqueológica y habiendo dejado varias cuestiones sin resolver. A través del presente artículo, el cual surge a partir de un capítulo de nuestra tesis doctoral, y tras llevar a cabo el análisis de los materiales arqueológicos, abordamos una reinterpretación cronológica de las secuencias estratigráficas y ofrecemos una serie de debates sobre el origen de Mazmullar, sus fases constructivas y de destrucción y abandono. Además, se estudia la problemática de su topónimo, de forma que todo el conjunto de resultados arroja una hipótesis histórica sobre la vida de este yacimiento muy diferente a la que tradicionalmente se ha empleado: una fase inicial para los siglos IX-X, seguida de otra califal con una destrucción entre finales del siglo XI y comienzos del XII y una segunda ocupación a lo largo del siglo XII con su correspondiente abandono en el siglo XIII.

Benign biliary stricture (BBS) is a complication of chronic pancreatitis (CP). Despite endoscopic biliary stenting, some patients do not respond to treatment, and they experience recurrent cholangitis. We report two cases of CP with refractory BBS treated using endoscopic ultrasound-guided choledochoduodenostomy (EUS-CDS) fistula creation. A 50-year-old woman and a 60-year-old man both presented with obstructive jaundice secondary to BBS due to alcoholic CP. They underwent repeated placement of a fully covered self-expandable metal stent for biliary strictures. However, the strictures persisted, causing repeated episodes of cholangitis. Therefore, an EUS-CDS was performed. The stents were eventually removed and the patients became stent-free. These fistulas have remained patent without cholangitis for more than 2.5 years. Fistula creation using EUS-CDS is an effective treatment option for BBS.

Background/Aims: Hepaticojejunostomy anastomotic stricture (HJAS) is a feared adverse event associated with hepatopancreatobiliary surgery. Although balloon dilation for benign HJAS during endoscopic retrograde cholangiopancreatography with balloon-assisted enteroscopy has been reported to be useful, the treatment strategy remains controversial. Therefore, we evaluated the outcomes and risk factors of recurrent stenosis after balloon dilation alone for benign HJAS.Methods: We retrospectively analyzed consecutive patients who underwent balloon-assisted enteroscopy–endoscopic retrograde cholangiopancreatography for benign HJAS at our institution between July 2014 and December 2020.Results: Forty-six patients were included, 16 of whom had recurrent HJAS after balloon dilation. The patency rates at 1 and 2 years after balloon dilation were 76.8% and 64.2%, respectively. Presence of a residual balloon notch during balloon dilation was an independent predictor of recurrence (hazard ratio, 2.80; 95% confidence interval, 1.01–7.78; p=0.048), whereas HJAS within postoperative 1 year tended to be associated with recurrence (hazard ratio, 2.43; 95% confidence interval, 0.85–6.89; p=0.096). The patency rates in patients without a residual balloon notch were 82.1% and 73.1% after 1 and 2 years, respectively.Conclusions: Balloon dilation alone may be a viable option for patients with benign HJAS without residual balloon notches on fluoroscopy.

Authors: Sultan Ghori Faheem , Ahmed Khalil , Mehmood Khan Dr. Kashif
Published: May 2023

Objective

To compare clinical and functional outcomes and complications of open reduction internal fixation (ORIF) by plating and Ilizarov technique in complex tibial plateau fractures.

Methods

This study is a randomized clinical trial accompanying 56 patients having Schatzker type V and VI tibial plateau fractures. We divided patients into two groups for management. Group I; open reduction internal fixation and Group II; ilizarov technique. We conducted study at the orthopedics department, Jinnah Post-Graduate Medical Center, Karachi, from April-2018 to Oct-2020. The endpoint was to assess patients’ satisfaction and clinical and functional outcomes up to an 18-month follow-up.

Results

The etiology of tibial fracture was mainly road traffic accident (RTA); 17 (70.9%) in ORIF versus 23 (71.8%) in the Ilizarov group. According to clinical outcomes, excellent extension lag was achieved in 100% of patients in both groups. Most patients had excellent knee flexion, thigh atrophy and instability outcomes (54.1% vs 59.37%, 87.5% vs 81.2% and 83.3% vs. 87.5%). The functional outcome assessment was done and recorded for 18 months of follow-up. There was no significant difference in normal walking, stair climbing, squatting, jumping and duck walking between the groups. The overall rate of complications was similar; 11 (45.8%) in ORIF versus 17 (53.12%) in the illizarov group (p=0.78).

Conclusion

Our study concludes that there is an excellent clinical and functional outcome found in both procedures as both are safe and effective procedures with fewer complications

Published: May 2023

Ibn Rushd was a Maliki cleric who lived in Andalusia (now Spain). This scholar who is known for his progressive philosophical thinking has books of comparative fiqh, four schools in particular. It describes various themes ranging from worship and muamalah. One of the topics studied in this paper is Ibn Rushd's thoughts on wadiah. Where according to Ibn Rushd Wadiah is a muamalah transaction related to material things. Therefore, globally, according to all scholars, it is obligatory for him to take care of entrusted goods from conditions that are normally guarded by human assets. So something that has been clearly assessed as a safeguard is allowed, while it is not clear that it is a safeguard then it is disputed, such as their dispute in the Malik school of thought regarding a person who puts a deposit in his pocket and then it is lost. According to the well-known opinion that the person should be held accountable.

Published: May 2023

Este estudo objetiva compreender a percepção da liderança na implementação de estratégias organizacionais à luz do BSC com base nos trabalhos (tese e dissertações) publicados entre os anos de 2005 a 2020. Como sustentação teórica foi abordado o tema liderança e administração estratégica e o Balance Scorecard (BSC): definição e aplicação. Dos 182 trabalhos submetidos na plataforma da Biblioteca Digital Brasileira de Teses e Dissertações (2016), somente 1(uma) tese e outras 10 dissertações dirigiram esforços para compreender a opinião da gestão sobre uso da ferramenta. Neste interim, não foram encontrados trabalhos que compreendessem a eficácia da aplicação no âmbito das organizações brasileiras. O que se encontrou foram estudos de casos que trataram do tema isoladamente. Esta pesquisa se caracteriza como qualitativa, cuja coleta dos dados se deu pela análise de conteúdo dos resultados dos trabalhos selecionados para análise. Sendo assim, o Balanced Scorecard demonstra como as decisões de uma determinada unidade estratégicas de negócio podem produzir efeitos não só sobre seus próprios resultados, mas também em toda a estratégia corporativa, relacionando e traduzindo as ações imediatas com os objetivos e metas de longo prazo, produzindo a sinergia necessária ao cumprimento da missão/visão da organização.
Participação social: o que e como está sendo abordada nos estudos nacionais
Authors: Leite Stella Pereira
Published: May 2023

Discutir o que e como está sendo estudada a participação social no Brasil, bem como identificar lacunas que ainda não foram supridas sobre essa temática. A pesquisa utilizou a revisão integrativa da literatura por meio da busca de artigos científicos nas bases Web of Science, ScIELO e CAPES. Os achados são consistentes com estudos anteriores que investigam a participação social sob a perspectiva das políticas públicas, instituições participativas, conferências, conselhos e orçamentos participativos. Por outro lado, evidenciam a necessidade de adotar novas metodologias a fim de ampliar a participação ativa de crianças na formulação de políticas públicas às quais são as principais destinatárias, bem como as contribuições teórico-analíticas acerca do fenômeno das redes focado na participação social. O campo de pesquisa vem se debruçando sobre políticas públicas, com destaque para a área da saúde, e sobre a estrutura, implementação e funcionamento dos conselhos, porém ainda com necessidade de uma maior publicização das experiências e dos conhecimentos gerados sobre os conselhos criados no âmbito dos orçamentos participativos. Verifica-se que há formatos institucionais de participação surgindo em nossa sociedade, no entanto se percebe a necessidade de se aprofundar as motivações para participação nesses espaços. Ainda, verificou-se a predominância de trabalhos empíricos, com uma quantidade significativa de estudos de casos e utilização de métodos qualitativos. Este trabalho contribui para o estudo da participação social no contexto brasileiro em dois aspectos: por apresentar uma revisão integrativa de literatura atualizada e pela adoção de protocolos de pesquisa detalhados e pautados na confiabilidade, a fim de permitir a sua reprodução. Além de identificar lacunas teóricas que ainda não foram supridas e que poderão contribuir para estudos futuros.
Single shot imaging for cold atoms based on machine learning

Published: May 2023

The ability to detect atoms in high spatiotemporal resolution provides a powerful tool for us to investigate the quantum properties of ultracold quantum gases. Plenty of useful imaging methods, including absorption imaging, phase contrast imaging and fluorescence imaging, have been implemented in detecting atoms. Among them, absorption imaging is the most widely used method in cold atoms laboratory. However, the traditional absorption imaging method is affected by perturbations such as interference between optical elements, fluctuation of laser power, frequency, and spatial position, resulting in residual spatially structured noise and degradation of imaging quality. Especially for regions with lower density or for longer time-of-flight, a large number of repetitions are often required to obtain better signal-to-noise ratio, which would increase the time cost and induce other noise. One must reduce the time between two imaging pulses to suppress the spatial noise. A better charge coupled device (CCD) with higher frame transfer rate or other method like fast-kinetic mode will be used to improve the imaging quality. In this paper, a single-shot cold atom imaging method based on machine learning is proposed, in which only one absorption imaging of cold atoms is required, and the corresponding background image can be generated through the neural network of an autoencoder. This effectively reduces the spatial striped noise in imaging, significantly improves the imaging quality, and makes it possible for cold atoms to be imaged multiple times in a single cycle.

Спектры испускания близки к исходным спектрам флуоресценции лигандов, лишь в случае иона меди(II) наблюдается практически полное тушение флуоресценции. Бензилимин демонстрирует селективное относительное увеличение интенсивности эмиссии I/I0 в 180 раз в присутствии катионов цинка. Все синтезированные имины проявляют отчетливый «naked-eye» эффект с изменением ярко-желтого цвета раствора на бледно-желтый в случае фторид- и цианид-анионов, тогда как остальные анионы незначительно влияют на характер абсорбции. В случае бензилимина отмечены рекордные значения относительного увеличения интенсивности эмиссии I/I0 – 470 и 575 для цианид- и фторид-анионов соответственно. Таким образом, бензилимин 4-формил-3-гидрокси-2-нафтойной кислоты представляет собой эффективный и селективный полифункциональный флуоресцентный сенсор для детектирования ионов Zn, F и CN.

На протяжении 2019–2022 гг. проведено комплексное изучение строения и истории формирования кос Долгой, Чумбурской, Павло-Очаковской и Беглицкой на южном и северном берегах Таганрогского залива Азовского моря. На основе послойных исследований кернов из 24 скважин, глубина которых составляла от 5,2 до 26,5 м, а также ряда береговых обнажений выделены основные этапы развития Азовского моря на протяжении позднего плейстоцена и голоцена. Верхняя часть осадочной толщи всех изученных кос сложена новоазовскими песчано-ракушечными отложениями, мощность которых увеличивается от основания к дистальным частям кос. Основой карбонатного материала новоазовских отложений являются раковины Cerastoderma glaucum, поступавшие с банок Железинской, Ахтарской и Еленина, из прибрежных частей и заливов Азовского моря. Этот слой залегает на серых мягкопластичных суглинках и илистых песках древнеазовского возраста лиманно-лагунного происхождения. Ниже вскрываются тугопластичные серые и голубовато-серые глины и суглинки, которые сформировались в начале голоцена в мелководном водоеме. На северном побережье (Беглицкая коса) эти отложения залегают на слое размытых верхнемиоценовых известняков. В разрезах скважин на косах южного побережья Таганрогского залива в интервале глубин 18–22 м вскрываются морские пески позднекарангатского бассейна начала позднего плейстоцена. Исследование поверхностного микрорельефа самой крупной косы южного побережья, Долгой, позволило выявить разновозрастные системы береговых валов, характеристики которых свидетельствуют о 5–6 стадиях ее развития.

Мангровые заросли играют важную роль в поддержании устойчивости прибрежной и окружающей сред малых островов. Они служат местом обитания различных видов рыб и являются показателем здоровья прибрежной экосистемы. В дальнейшем мангровые заросли также могут стать экономическими центрами для прибрежных сообществ благодаря сельскому хозяйству и туристической деятельности. Поэтому значение мониторинга мангровых зарослей с каждым годом становится все более важным. Одним из решений данной проблемы может стать использование дистанционного зондирования Земли для мониторинга состояния мангровых зарослей. Город Сурабая (Индонезия) является потенциально благоприятной территорией для произрастания различных видов мангровых зарослей. Целью этого исследования был мониторинг трех типов мангровых зарослей и площади их произрастания, а также определение величины биомассы и углерода, производимых ими в городе Сурабае. Были использованы данные снимков Landsat за 1994, 2003 и 2018 гг. и платформа Google Earth Engine с использованием алгоритма Random Forest. В индонезийской провинции Восточная Ява, как и в ее административном центре Сурабае, произрастают мангровые деревья, принадлежащие к трем родам: Rhizophora, Sonneratia и Avicennia. По сравнению с 1994 г. площадь мангровых зарослей в Сурабае в 2018 г. увеличилась на 429,954 га. Результаты показали, что чем больше мангровых зарослей в Сурабае, тем больше биомасса и углеродные запасы. Периодический мониторинг мангровых зарослей сможет поддержать устойчивость прибрежной экосистемы этого региона.
ОЦЕНКА РИСКА ЗДОРОВЬЮ, АССОЦИИРОВАННОГО С ПЕРОРАЛЬНЫМ ПОСТУПЛЕНИЕМ ЭКОТОКСИКАНТОВ ИЗ ПОДЗЕМНЫХ ВОД ПРИВОЛЖСКОЙ ПЕСЧАНОЙ ГРЯДЫ, "Наука юга России"

Статья посвящена анализу канцерогенных и неканцерогенных рисков здоровью, обуслов ленных пероральным поступлением токсикантов и связанных с ними эндемичных экозависимых заболеваний. Заволжская часть Волгоградской области характеризуется осложненными литологическими условиями водопользования, подвержена антропогенной нагрузке. Зачастую подземные воды являются единственным источником хозяйственно-питьевого водоснабжения в данном регионе. Анализ жесткости гидрокарбонатно-кальциевых вод выявил неоднородность пространственного распределения нестандартных проб на всей территории Приволжской песчаной гряды. По результатам исследований было зафиксировано присутствие в воде ряда кумулятивных токсикантов, обладающих локально-токсическим и канцерогенным эффектом. Наибольший неканцерогенный риск употребления подземных вод создают бор, железо и нитраты, наличие которых связано с природой водоносных горизонтов и нерациональным ведением сельского хозяйства. Основными критическими системами являются: пищеварительная, сердечно-сосудистая, репродуктивная, процессы эмбриогенеза. Присутствие тяжелых металлов, обусловленных антропогенным воздействием, способно вызывать аллергические реакции. Содержащиеся в подземных водах исследуемого региона канцерогены (тяжелые металлы, хлорфенольные соединения, гербициды) облагают опасным (для детей) и чрезвычайно опасным (для взрослых) уровнем потенциала развития онкологических стохастических эффектов при обнаружении их в концентрациях, значительно меньших, чем предельно допустимые. Безнапорная природа водоносных горизонтов Приволжской песчаной гряды, а также отсутствие зон санитарной защиты делает подземные воды уязвимыми к миграции экотоксикантов из прудов-испарителей и стоков с предприятий тяжелой промышленности и агрокомплексов. На основе полученных данных о наиболее опасных загрязнителях и их влиянии на здоровье населения возможно осуществление корректировки ряда профилактических мероприятий по предотвращению развития эндемичных для исследуемого региона экозависимых заболеваний.

Published: May 2023

Down syndrome is associated with multiple comorbidities like growth delays, eye abnormalities, cardiovascular complications etc. They can be screened to detect early and can be intervened at an appropriate age. Professional organizations and other parents’ support group can work towards streamlining the screening protocol and raising awareness.

Aim: To study the awareness about these comorbid conditions and their evaluations among parents of children with Down syndrome.

Methods: A cross section questionnaire-based study pilot survey was conducted after taking due consent from the parents. It contained questions regarding whether the parents were aware of the increased risk in different organ systems and whether they knew the recommended timeline for screening.

Results: More than 90 percent of mothers were below the age of 35 years at the time of conception. More than half the parents knew about growth delays, eye, thyroid, cardiovascular complications. Less than 50% had awareness about DS specific growth charts, or the annual thyroid evaluations, while none knew the upper age limit to complete polysomnography evaluation.

Conclusion: A majority of parents had varying degrees of awareness regarding the different comorbidities, type of evaluations to be done and the recommended timelines to screen for these conditions.

Objective: This study aimed to determine the prevalence, distribution, and treatment outcomes of tuberculosis (TB) in a rural hospital in Nigeria.

Methods: This was a retrospective cross-sectional study conducted between 2013 and 2022. The data on all patients diagnosed with TB during the study period were collected from the hospital's registry. The data was then entered into SPSS for analysis. The level of statistical significance was set at P < 0.05.

Results: The overall prevalence of TB among TB suspects was 41.3%. Pulmonary TB was the most common form of TB, accounting for 87.1% of the cases, while extrapulmonary TB accounted for 12.9%. Among extrapulmonary TB cases, TB lymphadenitis was the most common (27.2%). The mean age of the patients was 44.7±10.9 years, with the majority of cases in the 51-60 and 31-40-year age groups. Males were more affected than females (59.1% vs. 40.9%), and 5.6% of TB patients were HIV-positive. The frequency of rifampicin-resistant TB was 9.5%. The majority of patients (96.5%) had a successful treatment outcome, with 28.9% being cured and 67.6% completing their treatment. Treatment failure occurred in 0.4% of TB cases, while 0.9% defaulted, and 2.2% died. Patients with rifampicin-resistant TB had lower odds of treatment success than those without rifampicin-resistant TB (P = 0.03; OR: 0.5; CI: 0.26-0.96).

Conclusions: The study revealed that TB remains a significant public health problem in Nigeria, especially in rural areas. Therefore, there is a need for increased collaboration and stronger measures to prevent and control TB, particularly in low-resource settings.

Background: Gastric cancer (GC) is among the five most frequent cancer worldwide, following lung, breast, colorectal, and prostate cancer. It is the 12th most prevalent cancer in both sexes in Egypt, accounting for 1.6% of all malignancies. Distinct molecular subtypes of gastric adenocarcinoma (e.g., microsatellite instable subtype and P53 aberrant subtype) have been reported by different classification systems. However, the relation of these molecular subtypes to different clinicopathological features is still controversial.

Aim of the Work: To utilize the immunohistochemical expression of DNA MMR proteins (MLH1 and MSH2) and p53 to detect microsatellite unstable and P53 aberrant molecular types in gastric adenocarcinoma. Moreover, to correlate immunohistochemically detected microsatellite unstable and P53 aberrant molecular types of gastric carcinoma with different clinicopathological characteristics.

Materials and Methods: The immunohistochemical expression of MLH1, MSH2 and P53 proteins was evaluated in 70 cases of gastric adenocarcinoma.

Results: Microsatellite status/Mismatch repair status showed a statistically significant relation with WHO classification, tumor differentiation, lymph node status, and TNM staging. P53 aberrant type showed a statistically significant relation with tumor differentiation, depth of tumor invasion, lymph node status, and TNM staging.

Conclusions and Recommendations: Microsatellite instable GC and P53 aberrant GC are two distinct molecular subtypes of gastric adenocarcinoma with distinct clinicopathological features and different prognostic outcomes. Microsatellite instable tumors are associated with good prognostic parameters while, P53 aberrant tumors are associated with poor prognostic parameters. Both subtypes could be detected using immunohistochemistry and could represent potential targets for future therapeutic agents.
