Authors: Valle Espinoza Alfredo , Sevilla Avellan Susana , Obando Guerrero Grania Isabel
Published: February 2025

La pérdida del esófago es un problema no tan frecuente, pero de gran sufrimiento para el niño, angustia a la familia y un desafío técnico para el cirujano pediatra. Este trabajo evaluó la viabilidad y eficacia del reemplazo esofágico utilizando un tubo gástrico como alternativa en niños del Hospital Infantil Manuel de Jesús Rivera “La Mascota” entre noviembre del 2011 a noviembre del 2018. Se llevó a cabo un análisis observacional descriptivo que abordó las características sociodemográficas, las indicaciones, los resultados de la técnica quirúrgica y las complicaciones asociadas. Un total de 19 casos de reemplazos esofágicos (14 niños y 5 niñas), con edades entre 10 meses y 18 años (media 4 años), y un seguimiento promedio de 2.7 años, se identificaron 9 pacientes con complicaciones posquirúrgicas, siendo la fístula de la anastomosis la más frecuente (6 pacientes). Se llevó a cabo modificación en los momentos de la técnica quirúrgica, que pareciera influir en una disminución del índice de complicaciones. Es importante mencionar que un paciente falleció por una complicación no vinculada al procedimiento de reemplazo esofágico, los 18 pacientes restantes lograron recuperar con éxito la alimentación oral total. En consecuencia, se concluye que el reemplazo esofágico utilizando un tubo gástrico transhiatal retromediastinal es una técnica factible, reproducible y segura para restablecer la alimentación oral en niños. Además, se observó que al realizar el reemplazo esofágico comenzando por la etapa cervical seguido de la abdominal parece proporcionar una mayor seguridad y un menor número de complicaciones.

Abstract: With the continuous increase in energy consumption and the exacerbation of environmental problems, the energy transition is becoming increasingly urgent. Hydrogen, as a clean and zero-carbon energy source, has received extensive attention. Hydrogen-doped natural gas transportation technology has emerged as a promising solution to the challenge of large-scale hydrogen transportation. This article comprehensively reviews the development history of hydrogen doping technology in both China and around the world, and systematically analyzes the effects of hydrogen-doped natural gas on pipeline tubing, including the phenomena of hydrogen embrittlement, hydrogen permeation, leakage diffusion, and ignition explosion. The advantages of this technology, such as significant carbon emission reduction and enhanced energy utilization efficiency, are thoroughly examined. The challenges it faces, such as the elevated safety risks due to the flammability and explosiveness of hydrogen, the immaturity of production technologies, and the inadequacies in regulations and standards, are also meticulously pointed out. Looking ahead, in-depth technical research and development, the innovation of hydrogen production technologies, and the establishment of robust regulations and standards are crucial to facilitating the hydrogen-doped natural gas transportation technology to play a more prominent role in the energy field and to promoting the sustainable development of energy. Additionally, with the continuous innovation and breakthroughs in technology, it is expected that the hydrogen blending ratio can be further increased. For example, the hydrogen blending ratio in some regions may be raised to approximately 30% by 2030, thereby further reducing carbon emissions and accelerating the transformation of the energy structure towards clean and low-carbon.

Authors: Noorali Imad Salih , Attiya Marwa Akram , Alzaidi Zaid Abdullah
Published: February 2025

Background: Fractures of the mandibular condyle result in displacement of the condyle and decrease the ramus height. There are several surgical approaches for open treatment of the fractures. Surgical approaches to the fractured mandibular condyle are broadly classified into intraoral and extraoral approaches. A retromandibular approach is the most commonly used for open reduction and internal fixation of such fractures. Objective: To compare the complications associated with a retromandibular transparotid approach with a retromandibular transmasseteric anterior parotid (TMAP) approach for their management. Methods: Twenty-four patients were included in this study and divided into two groups: Group A included the retromandibular TMAP and Group B retromandibular transparotid approach. The variables evaluated were operating time and facial nerve injury at one week, four weeks, and three months. Results: The mean age in groups A and B was 26.92 and 23.82 years, and there were 20 men and 4 women. The transparotid group showed a shorter incision time (13.8 min) compared to the transmasseteric group (26.3 min). The incidence of facial nerve injury was a single patient in the transparotid group and none in the TMAP group. The results did not show any significant difference in complications between the two approaches. Conclusions: The retromandibular transparotid and transmasseteric approaches are safe and effective methods in the management of subcondylar fractures of the mandible.

Osmotic demyelination syndrome (ODS) is a non-inflammatory demyelination illness and it includes both central pontine myelinolysis (CPM) and extrapontine myelinosis (EPM). These neurological conditions can rarely develop after alcohol withdrawal. While the precise pathophysiology of EPM and CPM is still unknown, various studies indicate that vasogenic edema is a major element in EPM while cytotoxic edema is a key factor in CPM. Here we present two patients who were diagnosed with central pontine myelinolysis following alcohol withdrawal and showed improvement with steroid therapy. Further studies are needed to demonstrate the effectiveness of steroid treatment in these patients. This case is highlighted due to the rarity of the disease and the observed benefits of high-dose steroid therapy.

Published: February 2025

Fraud in the insurance industry continues to present significant challenges, resulting in billions of dollars in losses annually. Traditional methods of fraud detection, relying on human expertise and rules-based systems, are increasingly unable to keep pace with the growing sophistication of fraudulent schemes. This paper explores the transformative role of artificial intelligence (AI) and machine learning (ML) in addressing these challenges. By reviewing various AI-driven fraud detection techniques, including predictive analytics, deep learning, and real-time decision systems, this study demonstrates that AI models can improve fraud detection accuracy by up to 30%, significantly reduce operational costs, and provide real-time fraud prevention capabilities. The research highlights key case studies across auto, health, and life insurance, showcasing the successful implementation of AI systems and their impact on fraud reduction, operational efficiency, and customer satisfaction. Despite the clear advantages, the paper also addresses several ethical concerns, including bias in AI models, data privacy, and transparency, emphasizing the need for responsible AI deployment in fraud detection. Furthermore, the paper discusses future research directions, including the exploration of emerging technologies such as blockchain, reinforcement learning, and deep learning, to further enhance the effectiveness of fraud detection systems. The findings suggest that AI-powered fraud detection is essential for the future of the insurance industry, providing a scalable, efficient, and ethical solution to combat fraud.

Published: February 2025

In this article, we theoretically evaluate the impact of natural resources on the growth and development of rentier economies, of which the DRC is part through the induced effects of Dutch disease, drawing inspiration from the economic situation of the Netherlands in the 1970s, due to the export of natural gas and by the effects caused by the deterioration of the governance of the country's various institutions based on the psychology of the leaders. The aim is to assess the choice of diversification of mining exports from the DRC as an alternative to escape the curse of natural resources. Industrialization and the change in attitudes of its leaders are fundamental and essential determinants of economic results and the export success of Congolese companies, beyond demographics, savings, physical capital and human capital.

Canada–U.S. Trade in a Globalized Economy: Elasticities, Asymmetries, and Policy Imperatives
Authors: Warin Thierry
Published: February 2025

This study examines the intricate trade interdependencies between Canada and the United States, highlighting how aggregate export–import figures can mask deeper economic realities. Approximately three-quarters of Canadian merchandise exports head to the United States each year, contributing to a bilateral merchandise trade surplus for Canada in the range of 100 to 170 billion Canadian dollars. Yet, when energy products are excluded, the United States shows a small surplus with Canada, illustrating how both sides benefit from specialized cross-border value chains. Analyses of selected sectors demonstrate that a hypothetical 25 percent tariff on Canadian goods would translate into lost export revenue for Canada, but it would also raise production costs for many U.S. manufacturers dependent on Canadian imports.

Despite Canada’s smaller economy, the potential for economic harm runs in both directions. Automakers in Michigan and Ohio, for instance, rely on numerous Canadian inputs that cross the border multiple times, and integrated refiners on the Gulf Coast often process crude oil from Alberta. Inelastic supply chains amplify these vulnerabilities: short-run elasticity estimates indicate that energy flows might see only a 2 percent immediate reduction under a 10 percent tariff, yet over a longer horizon, both sides risk further setbacks if either country shifts to alternative markets. On both sides, adjustments to cross-border barriers are neither simple nor immediate because specialized capital investments and elaborate production networks cannot be realigned without significant cost.

These findings underscore the limitations of viewing trade solely through the lens of net balances. They suggest that resilience policies, dispute-resolution frameworks, and incremental diversification strategies are integral to mitigating risk. In a climate where protectionist rhetoric can swiftly translate into new barriers, maintaining stable, predictable conditions for trade in both Canada and the United States is essential to preserving the mutual gains flowing from decades of close economic integration.

Las adenopatías reactivas son de mayor tamaño, pero suelen conservar la forma ovoidea o fusiforme y el hilio central.
Las adenopatías malignas suelen tener forma redondeada, con cortical engrosada y pérdida del hilio central. Es frecuente que presenten ecogenicidad heterogénea con focos anecoicos y ocasionalmente calcificadas.
El estudio de los diámetros de la adenopatía sugiere malignidad cuando el eje corto es >10 mm y la relación eje largo/eje corto es <2.
Algunas adenopatías reactivas pueden tener características ecográficas de malignidad.
La vascularización (Doppler color) suele mostrar vascularización central hiliar en las adenopatías reactivas, mientras que en las adenopatías malignas suele ser periférica o difusa.
La ecografía clínica permite no solo estudiar las características de las adenopatías, sino también realizar el diagnóstico diferencial con otro tipo de masas que se pueden localizar en las regiones anatómicas afectadas.

¡Doctora! ¿Tengo alergia al pescado a estas alturas?
Authors: Naturil Hoes Vanessa , Sánchez Sánchez Lourdes
Published: February 2025

La escombroidosis se produce cuando ciertos pescados, especialmente del tipo escombroide como el atún, no se refrigeran adecuadamente, permitiendo que bacterias transformen la histidina del pescado en histamina.

A pesar de no ser una alergia real, los síntomas de escombroidosis imitan una reacción alérgica, incluyendo urticaria, prurito, cefalea y, en algunos casos, dificultad para respirar.

La mejor manera de diferenciar entre una alergia al pescado y una intoxicación por escombroides es la determinación analítica de valores altos de histamina y valores normales de inmunoglobulina (Ig)E. Estas pruebas no siempre están disponibles o son fiables, por lo que el diagnóstico suele ser clínico.

Generalmente es manejable y se trata con antihistamínicos para aliviar los síntomas. Aunque algunos casos llegan a precisar tratamiento con corticoides o adrenalina, según la gravedad..

Este artigo propõe um estudo sobre a integração da sustentabilidade e circularidade nas compras públicas, tendo como fundamento teórico a Teoria Institucional. É feito um arcabouço teórico sobre teoria institucional, e sobre compras públicas sustentáveis com foco na circularidade. Para atingir o objetivo proposto, optou-se por utilizar o procedimento da revisão integrativa de literatura seguindo o protocolo proposto por (Cronin et al., 2008), abrangendo artigos publicados nas bases Scopus, Science Direct, e Web of Science, e Directory of Open Access Journals, sem corte temporal. Além de sintetizar o conhecimento acerca do tema, traz uma agenda de pesquisa ampliada com a identificação dos estudos propostos nos artigos da revisão, bem como apresenta novos estudos a partir do tema sob enfoque. Este estudo contribui para o desenvolvimento teórico das compras públicas sustentáveis com foco na circularidade através da conjunção e amadurecimento dos temas em foco; contribui para o desenvolvimento prático por meio das propostas de implementação sistematizadas no trabalho; e contribui para o desenvolvimento social com as discussões sobre a sustentabilidade e a circularidade, que são comportamentos que afetam a todos como sociedade.

This systematic review aims to compare the postoperative sensitivity of self-etching and total-etching adhesives systems in restorations of non-carious cervical lesions by analyzing randomized clinical studies. Following PRISMA recommendations, six recognized databases (Cochrane Library, EMBASE, LILACS, Pubmed, Scopus, Web of Science) and the grey literature were used to search for articles in October 2024. Only randomized clinical trials, carried out on humans, of any duration and year of publication, which compared and evaluated postoperative sensitivity in restorations of non-carious cervical lesions (NCCL) using self-etching and total-etching adhesives were included. Uncontrolled clinical trials, editorial letters, pilot studies, case reports, and case series were excluded. The quality of the articles was analyzed using the Risk of Bias Tool for Randomized Trials (RoB 2.0). The results of data extraction from the selected articles were tabulated in spreadsheets to examine the outcomes assessed. Self-etching adhesive systems showed variable performance compared to total-etching adhesives in reducing postoperative dentin sensitivity. The ten studies included in the systematic review had some risk of bias, revealing the need to pay attention to the criteria for conducting randomized clinical trials. When compared, the control and test groups did not show a significant reduction in postoperative sensitivity in NCCLs, and there was great variability in the effects of the studies.

Moçambique é um dos países mais afetados pelas inundações na África, registrando mais de 20 inundações nos últimos 30 anos, o que tem causado danos ao do país e atrasando o seu desenvolvimento. Este estudo teve como objetivo analisar as áreas suscetíveis a inundações na Província de Manica, Moçambique, utilizando imagens de satélite Sentinel-2 e dados SRTM, processados no ArcGIS® 10.3. A metodologia possibilitou a criação de mapas temáticos para identificar áreas de risco, a partir da análise de fatores como tipos e usos do solo, altimetria, declividade e precipitação, que foram reclassificados e ponderados através da técnica de Análise Hierárquica de Processos (AHP). A Razão de Consistência (RC) de 0,06 foi considerada adequada para a consistência do modelo. Os resultados mostraram que um terço do território de Manica (34,13%) apresenta baixa suscetibilidade a inundações, entretanto uma área de 21,73% da província, áreas apresentam risco muito alto de sofrerem com inundações, sendo que os distritos de Mossurize, Sussundenga, Macate, Gondola e a cidade de Chimoio, são as regiões mais vulneráveis, devido à agricultura de subsistência, práticas inadequadas de manejo e infraestrutura deficiente. O aumento da urbanização e a impermeabilização do solo exacerbam os riscos de inundações, especialmente durante períodos de chuvas intensas.

Thrombus refers to macrovascular sparing, which interrupts partially or completely blood flow. Its formation involves Virchow's triad, characterized by three main predisposing factors: endothelial injury, vascular stasis and hypercoagulability. The case reported was a canine, with a history of three thrombotic formations at different times of life, one in the splenic vein, undergoing splenectomy, and the other two in the right branch of the portal vein, undergoing surgical excision. The patient was under treatment with antithrombotic therapy, but with no response. Due to an uncompensated chronic kidney disease, the animal died a few weeks after the last procedure, with a cause of death of cardiogenic shock. It is mainly suspected that acute chronic kidney disease is the main cause of thrombosis, associated with chronic pancreatitis that re-aggravated in the first postoperative. However, the formation of thromboembolism is multifactorial, and its development and occurrence is still not fully elucidated. Thus, more studies and tests are needed, such as thromboelastometry.

Este estudo investiga a Gestão Integrada da Zona Costeira (GIZC) no Ceará, analisando políticas públicas voltadas à mitigação da erosão costeira e ao desenvolvimento sustentável. A pesquisa examina o impacto da retenção de sedimentos nos reservatórios sobre os processos erosivos litorâneos, destacando como a gestão inadequada dos recursos hídricos influencia a dinâmica costeira. A metodologia adotada combina abordagens qualitativas e quantitativas, incluindo levantamento de dados secundários, análise de imagens de satélite e modelagem físico-matemática da evolução da linha de costa. Foram estudadas as bacias hidrográficas dos rios Acaraú, Curu e Jaguaribe, considerando seus impactos na erosão costeira. Os resultados indicam que a construção de barragens e açudes reduz significativamente o transporte de sedimentos para a costa, intensificando a erosão em diversas áreas. A pesquisa evidencia a necessidade de ações preventivas, monitoramento contínuo e integração de políticas públicas para minimizar os impactos ambientais e socioeconômicos. Conclui-se que a implementação de estratégias adaptativas fundamentadas em evidências científicas é essencial para garantir o equilíbrio entre a conservação ambiental e as demandas socioeconômicas. Nesse contexto, a Gestão Integrada da Zona Costeira (GIZC) se destaca como a abordagem mais eficaz para fortalecer a resiliência das regiões costeiras, minimizando os impactos das mudanças climáticas e das intervenções humanas.
