Published: July 2024

Introduction: Acute intestinal intussusception secondary to an isolated local lesion (Meckel's diverticulum, a benign or malignant tumor, etc.), forming part of a more general pathology of the digestive tract (rheumatoid purpura, cystic fibrosis, etc.) or occurring in a particular context (Acute postoperative intestinal intussusception, chemotherapy, etc.). Observation: 15-year-old child, male, without known ATCD, admitted for occlusive syndrome which had been evolving for 5 days before his admission marked by diffuse abdominal pain associated with early postprandial vomiting of food type then bilious, with cessation of matter and gas. On clinical examination, he presented an altered general condition, afebrile at 37°5, the abdomen was slightly distended, tympanic, tender, without palpable mass. The rectal bulb was empty on rectal examination, with no signs of rectal bleeding. The ionogram was disturbed with hypokalemia and hyponatremia with white blood cells at 15,000. CT revealed a rounded image with small bowel distention, digestive thickening and moderate effusion. The child benefited from resuscitation measures to correct hydro-electrolyte disorders before the operating room. Exploration found ileo-ileal intussusception, with necrosis of the ileal loops 15 cm from the Bauhin valve, with the presence of a hyperemic nodular mass. A resection of the necrotic ileal loops removing the hyperaemic nodular mass, with creation of an end-to-end small intestine anastomosis. The piece was sent to the laboratory for a histopathological study, which came back in favor of a benign mesenchymal tumor whose histological and immunohistochemical appearance was compatible with a fibroma. After 01 year, the evolution was favorable. Conclusion: Ileo-ileal intussusception secondary to a fibroma is rare. Nonspecific symptoms make diagnosis difficult. Treatment is based on surgery.

Darier-Ferrand dermatofibrosarcoma is a rare skin tumor, generally diagnosed late, given its character, its slow and painless evolution as well as its lack of awareness by practitioners. After histological confirmation, treatment is planned according to the location and extent of the lesions in order to predict possible aesthetic and functional sequelae. Surgical resection and the gold standard. It is because of the high recurrence rate associated with wide local excision, the introduction of Mohs micrographic surgery, when the technical platform is suitable, has really helped to reduce recurrence rates dermatofibrosarcoma. But skin reconstruction, after significant loss of substance secondary to a resection respecting safety margins, represents a surgical challenge. Imatinib is recommended for neoadjuvant treatment to reduce tumor mass as well as in cases of unresectable or metastatic tumors. radiotherapy can be offered after incomplete surgery without any benefit after complete resection. In this paper we report the case of a patient operated for extensive lesions of the subumbilical wall in favor of a Darier-Ferrand dermatofibrosarcoma whose management of the loss of substance was a surgical challenge.

Among the causes of acute abdomen encountered in the emergency room, omental pathology remains rare and is little known by practitioners. Idiopathic omental torsion is part of it, whether primary or secondary, its clinical presentation is non-specific, including atypical abdominal pain and the main symptom. Which exposes one to an error or even a delay in diagnosis given the multitude of differential diagnoses. Abdominal CT remains the examination of choice to make the diagnosis. In case of doubt, surgical exploration, preferably laparoscopic, allows the diagnosis to be made as well as treatment by performing an omentectomy. The choice of therapeutic approach, conservative or omentectomy, remains controversial in the literature. In this article we highlight the diagnostic and therapeutic challenges of this entity through the case of a 53-year-old patient admitted for acute abdominal pain, whose investigations reveal an idiopathic omental torsion and also exposing the results of the two therapeutic approaches.

Published: July 2024

Pulmonary agenesis is a rare congenital anomaly defined by the total absence of pulmonary parenchyma, bronchi and vessels. It is often associated with other malformations. We report the case of a late revelation of right pulmonary agenesis in a 3 year old patient, presenting with recurrent episodes of respiratory infection. Chest radiography showed an opaque right hemithorax. The diagnosis of right lung agenesis was confirmed by chest CT scan with contrast enhancement. In our case pulmonary agenesis was associated with ipsilateral rib synostosis. CT scan is the main imaging modality for establishing a diagnosis of pulmonary agenesis, as well as demonstrating other associated malformations.

A lesão autoprovocada, de acordo com a Classificação Estatística Internacional de Doenças e Problemas Relacionados à Saúde (CID-10), consiste em atos desferidos intencionalmente pela pessoa a si mesma, que engloba a tentativa de suicídio. Os dados demonstram crescimento progressivo do delineamento epidemiológico, porém, por se tratar de um país em desenvolvimento, o Brasil apresenta limitação de coleta desses dados que fundamentem as taxas de suicídio com acurácia. Tal questão distorce as decisões políticas, uma vez que devem ser direcionadas por tais dados, que contribuem para o desenvolvimento e avaliação de intervenções, para o controle e prevenção de problemas de saúde. Objetivo: Identificar o perfil da mortalidade ocasionada por lesão autoprovocada notificada no estado de Alagoas no período de 2012 a 2022. Métodos: Estudo epidemiológico, analítico do tipo transversal, com um recorte de série temporal utilizando dados secundários extraídos do Sistema de Informação sobre Mortalidade (SIM), relacionados aos óbitos por lesões autoprovocadas intencionalmente entre os anos de 2012 a 2022. Resultados: Notou-se que, em Alagoas, a maioria dos óbitos por lesões autoprovocadas nos anos de 2012 a 2022 foram homens, na faixa etária de 20 a 24 anos, de cor parda. O maior número de casos ocorreu na capital, seguido por Arapiraca e Palmeira dos Índios. Conclusão:  A associação entre os casos de lesões autoprovocadas em Alagoas e o perfil obtido pode se dever ao impacto causado pelas redes sociais, as consequências do racismo e o estigma social em que homens usufruem menos dos serviços de saúde.

A escala de Mallampati (EM) é um escore de quatro níveis (cinco se for utilizada a EM modificada) que almeja predizer a dificuldade de uma intubação orotraqueal (IOT) ou a dificuldade na ventilação bolsa-válvula-máscara (VBVM) no manejo da via aérea (VA) de um paciente antes de receber anestesia geral para fazer um procedimento. O presente estudo busca revisar a literatura e aumentar o conhecimento científico da escala de Mallampati, especialmente pela sua simplicidade e capacidade de auxiliar no manejo da via aérea difícil. Assim, com dados mais atualizados, pode-se fomentar melhores estratégias de quando aderir a EM, aumentar o preparo dos profissionais de saúde a fim de se evitar complicações nos procedimentos que irão requerer anestesia geral, além de identificar se a escala ainda é útil para a prática clínica-cirúrgica atual. Para elucidar as informações acerca da utilização da escala de Mallampati, foi usada uma metodologia sistemática, realizando uma revisão criteriosa da literatura, através da base de dados eletrônica Scielo. Após a leitura dos 05 artigos selecionados, as informações consideradas relevantes para compor esta revisão de literatura foram tabuladas, concluindo-se que a escala de Mallampati ainda é bastante estudada e utilizada, sendo um teste clínico de fácil acesso e rápida aplicação, com eficácia para a predição de via aérea difícil. No entanto, estudos demonstram que a escala utilizada de forma individual não possui grande valor preditivo, devendo ser utilizada com outros testes em associação.

Introdução: A adolescência é um período de vulnerabilidade no qual os jovens estão mais suscetíveis a mudanças biopsicossociais e passam por transformações na identidade pessoal. A sexualidade é construída a partir do convívio social e de aspectos físicos em transição. Assim, o processo de evolução sexual constitui um importante fator da personalidade do adolescente e é essencial a disseminação de informações sobre essa fase e suas respectivas influências. Objetivo: Avaliar os aspectos sociais, culturais, psicológicos e físicos os quais atuam no desenvolvimento sexual dos adolescentes. Metodologia: Foi realizada uma revisão bibliográfica de 13 artigos os quais abordam aspectos psicossociais da adolescência e sexualidade encontrados nas bases de dados  SciELO, PubMed e Google Scholar entre os anos 1998 e 2016. Resultados e discussão: As transformações da adolescência são constantemente influenciadas pela mídia e pelo conhecimento limitado acerca da sexualidade, além de fatores socioeconômicos. Tal fato é predisponente para que haja maior número de infecções sexualmente transmissíveis (ISTs), gravidez não planejada, falta de planejamento familiar, dentre outras questões. Sendo assim, nota-se a importância da informação acerca da sexualidade. Conclusão: Percebe-se então que a adolescência é uma fase de diversas mudanças e é de extrema importância promover ações de educação em saúde, como nas escolas e Unidades de Saúde, a fim de tornar o tema mais acessível, com menos tabus e garantir que haja um desenvolvimento sexual com maior responsabilidade e consciência.

Authors: Najm Abed Abdullah , Singh Dr. Surinder
Published: July 2024

The Bharatiya banking industry has adopted green accounting techniques, which entail incorporating environmental factors into the processes of financial reporting and decision-making. The objective of these practices is to evaluate and take into consideration the effect that banking activities, such as choices about lending and investments, as well as internal operations, have on the wider environment. Banks in Bharatiya use green accounting practices in order to assess, monitor, and report their environmental performance. These practices include their emissions of greenhouse gases, their consumption of energy and water, their waste creation, and their consumption of water. The implementation of sustainability reporting frameworks, such as the Global Reporting Initiative (GRI) and the Principles for Responsible Banking (PRB), which provide criteria for the disclosure of environmental, social, and governance (ESG) information, is required to accomplish this. Additionally, in order to identify and manage any possible environmental hazards that may be linked with their operations and investments, financial institutions may participate in environmental risk assessment and mitigation measures. Accounting techniques that are environmentally friendly allow Bharatiya banks to contribute to the achievement of sustainable development objectives while also improving the level of openness and accountability in their business operations.

Published: July 2024

Este trabajo aborda el desafío crítico de predecir la volatilidad en el mercado financiero, enfocado específicamente en el Índice Minero S&P BVL del sector minero peruano. La dificultad radica en la naturaleza compleja y dinámica de la volatilidad, que presenta desafíos significativos para los inversores y gestores de riesgos en la toma de decisiones informadas y estratégicas. Se propone evaluar la efectividad de un modelo híbrido de Regresión de Vectores de Soporte con Generalized Autoregressive Conditional Heteroskedasticity (SVR-GARCH) que incorpora un kernel lineal, frente a los enfoques convencionales GARCH. Metodológicamente, el estudio utiliza un diseño cuantitativo, recabando y procesando datos históricos diarios a través de la API de Yahoo! Finance con herramientas de programación en Python, abarcando un período desde el 31 de enero de 2014 hasta el 12 de febrero de 2024. Se implementa la prueba de raíz unitaria Dickey-Fuller Aumentada (ADF) para determinar la estacionariedad de la serie temporal. Los hallazgos indican que el modelo SVR-GARCH-Linear propuesto no solo proporciona predicciones más precisas en comparación con los modelos estándar, sino que también demuestra ser robusto frente a las fluctuaciones del mercado y sensibilidades específicas del índice minero. Concluimos que el enfoque híbrido representa una mejora significativa en las herramientas de predicción y gestión de riesgos, con aplicaciones prácticas que podrían extenderse a otros índices y mercados financieros, demostrando la necesidad de incorporar técnicas de aprendizaje automático en la modelización financiera contemporánea.

Published: July 2024

Supported bimetallic gold-palladium (AuPd) nanomaterials have been extensively studied as highly active and selective nanocatalysts for oxidation reactions. For long-term viability, optimizing synthesis and reaction parameters is essential for utilizing noble-based materials once they are expensive to produce on a large scale. For that reason, using a performance-focused strategy like a multivariate experimental design is an optimal solution for simultaneously investigating the effects of different parameters and implementing such materials in business activities. Therefore, herein, we report a systematic multivariate optimization of model AuPd/SiO2 nanocatalysts for selective benzyl alcohol oxidation in solvent-free sustainable conditions, which allows for the evaluation of the impact of the material synthesis and reaction conditions on the process and optimization of reaction and calcination temperatures. Our multivariate analysis shows that the calcination temperature has considerably impacted the structural properties of gold nanoparticles; still, these changes did not produce a pronounced effect on the material’s catalytic properties. On the other hand, the physical variables of reaction time and temperature had a more significant influence on both conversion and selectivity. An 18% conversion of benzyl alcohol with a benzaldehyde selectivity of 93% was achieved under a 562 ◦C catalyst calcination temperature, 100 ◦C reaction temperature, and 4 h of reaction time.

It is crucial to secure digital assets and networks against harmful activity in the linked world of today. Through the detection and mitigation of unauthorized access, malicious activity, and possible security threats, Intrusion Detection and Prevention Systems (IDPS) are essential to the protection of systems and networks. The development, approaches, technologies, difficulties, and future directions of intrusion detection and prevention systems are all covered in detail in this research paper. The study examines the advantages and disadvantages of several IDPS methodologies, such as hybrid, anomaly-based, and signature-based techniques. It also addresses how to improve the efficacy and efficiency of IDPS using cutting- edge methods like big data analytics, artificial intelligence, and machine learning. In addition, the study discusses and suggests possible solutions for the problems that IDPS faces, including false positives, evasion strategies, and scalability concerns. In order to assist academics, researchers, and practitioners with insights, it concludes by outlining future directions for study and development in the field of intrusion detection and prevention systems.
Recenser l’Égypte
Authors: Labib Malak
Published: July 2024

Dans la décennie qui précède l’occupation britannique (1882), l’Égypte est placée sous tutelle financière internationale, dans un contexte de crise de la dette. Émissaires, diplomates et banquiers européens mènent des enquêtes visant à recenser ses ressources économiques. Le présent ouvrage prend pour point de départ ces enquêtes afin d'explorer plus largement l’histoire de la statistique et de la quantification en Égypte à l’ère de la première globalisation financière.Des débats autour du budget à la réforme de l’impôt et à celle des poids et mesures, cet ouvrage s’intéresse aux lieux, aux acteurs et aux modalités de la fabrique du chiffre. Il montre comment, dans un contexte de crise, l’évaluation des ressources publiques devient un enjeu de négociations et de luttes, où s’entrecroisent problèmes techniques et politiques. Il permet d’appréhender sous un jour nouveau l’histoire économique de l’Égypte à l’ère impériale et de placer le cas égyptien dans une histoire transnationale de la quantification et de la statistique.
‘Is that not Titian?’ Echoes of Venice in George Frederic Watts’s Self-Portraits, between Self-Fashioning and Artistic Practice
Authors: Vitacca Sara
Published: July 2024

The reception of Venetian Renaissance painters had a profound
effect on the creation of a British tradition of painting and played
an important role in the development of the portrait as a typically
British genre. This is precisely what this article aims to explore,
through the emblematic case of the self-portraits of Victorian artist
George Frederic Watts. Many of the artist’s self-portraits, in fact,
explicitly engage with the tradition of Venetian art, and do so in
multiple ways. On the one hand, the artist models himself on the
figure of Titian, playing with the pose, the gesture, and the physical
resemblance with the old master. On the other hand, Watts also aims at
mastering the secrets of Titian’s painting method, which he discovered
through the reading of ancient painting treatises. Thus, the
relationship with the Renaissance plays a double role here, as it
shapes the public and private image of the artist, but it also affects
his artistic practice, and the very materiality of his paintings. This
paper will also contextualize Watts’s ‘venetianism’ with that of
Frederic Leighton, mid-Victorian photography, and the decadent painter
Charles Ricketts, drawing a broader picture of the fascination with
Venetian art in late 19th-century England.
L’étrange héritage des conversation pieces chez Stanley Spencer : du XVIIIe siècle au XXe siècle
Authors: Louvel Liliane
Published: July 2024

Stanley Spencer R.A. est renommé pour ses Résurrections, ses étranges séries inspirées de textes sacrés, pour ses « fresques » du Mémorial de Burghclere entre autres. Son œuvre révèle aussi un goût pour l’art du portrait dont certains se rattachent à la tradition des Conversation Pieces, ces tableaux de famille du XVIIIe siècle, qui ont participé à la construction de l’identité britannique. Or, S. Spencer a souvent été qualifié de « peintre anglais », en particulier à cause de sa célébration des paysages ruraux de son Berkshire natal, et de Cookham, son village bien aimé. Certains de ses portraits témoignent d’une résurgence de dispositifs caractéristiques du genre avec de petits groupes de personnages dans leur environnement familier. Les portraits de personnalités comme ceux du Dr Osmund Frank, maire de Maidenhead et de sa femme, de J. E. Martineau ou encore de J. L. Berhend, ses amis et commanditaires, les situent aussi dans leur décor intime. Le portrait de Mr and Mrs Baggett s’ouvre sur une fenêtre qui donne sur un cimetière, rappel du motif favori de Spencer. Ce dispositif d’une fenêtre située à l’arrière-plan, était également présent dans le portrait de Mr et Mrs William Lindow de G. Romney (1772). Une étude rapprochée de l’héritage de l’art du portrait anglais dans les œuvres d’un peintre aussi « excentrique » et souvent déconcertant que le fut S. Spencer sera donc proposée.
Portrayal or Betrayal? A Few Thoughts on Milton’s Curls
Authors: Laurent Béatrice
Published: July 2024

In one of his most frequently reproduced portraits, John Milton
appears as a young man, depicted in a three-quarter view, looking
sideways, not directly at but rather beyond the beholder. His small
mouth and undereye lids hint at a faint smile. He has rather thick
eyebrows, a straight nose, and the full cheeks and round chin of a
youth. His long hair parted in curtains falls in graceful curls far
below his shoulders, over his white collar and black robe. This
familiar image that the general public associates with the name of
John Milton differs however from authenticated portraits of the poet,
and results from a series of alterations that started in the 19th century. The purpose of this essay is twofold:
firstly, to trace the modifications made on portraits of the author of
Paradise Lost, and to study them in the context
of changing aesthetic preferences and psychological debates; secondly,
to initiate a theoretical reflection on historical portraits. Drawing
on recent scholarship on biofiction, this article will suggest that
distorted images affect the portraits of “great men” by fictionalizing
historical figures and presenting “iconofictions” that pass as
portraits. Located at the intersection of art, history, and biography,
this paper intends to discover how a modified portrait of John Milton
became iconic even while it lost its status as a documentary
piece.
La bande dessinée pour construire une mémoire des « mille jours » de l’Unité populaire au Chili
Authors: Marsande Elsa
Published: July 2024

La richesse du format de bande dessinée permet de bien dépeindre le Chili de 1971 à 1973, de la mise en place à la mise en échec du projet porté par Salvador Allende. On y démontre que le coup d’État n’est pas advenu par surprise : attentats, grèves et scandales se sont imposés en réponse à la mise en place du programme de l’Unité populaire. Le foisonnement politique et social qui émerge de ce moment, les multiples reconfigurations et les tensions qui s’y installent, sont restitués dans une fresque historique d’une précision exemplaire.
