Hepatitis B and Celiac Disease: a cause for concern?
Authors: Narciso-Schiavon Janaina Luz , Schiavon Leonardo de Lucca
Published: December 2023

Some theories suggest that the development of the immune response to clear hepatitis B triggers the intestinal tissue damage seen in celiac disease in genetically predisposed individuals. Although the role of hepatitis B virus infection in the development of autoimmune diseases has been widely discussed in the literature, it remains a controversial topic. Our objective is to review whether there is an association between hepatitis B and celiac disease and the particularities of vaccination against hepatitis B in celiac patients.

Published: December 2023

Antecedentes: las prótesis metálicas autoexpandibles mejoran la disfagia en pacientes con cáncer esofágico (CE) incurable. En las últimas décadas se han introducido nuevos tipos de stents y se ha implementado la quimiorradioterapia para el CE, generando cambios en los perfiles de riesgo de los pacientes. Se desconoce si estos cambios han afectado la paliación con stents.
Pacientes y métodos: estudio retrospectivo en tres centros de Medellín-Colombia; pacientes sometidos a colocación de prótesis esofágicas paliativas para disfagia maligna (1997-2022). Se evaluaron en dos períodos: 1997-2009 (n = 289) y 2010-2022 (n = 318), complicaciones mayores y menores después del implante, la influencia de las terapias oncológicas y la sobrevida.
Resultados: se evaluaron 607 pacientes sometidos a prótesis esofágicas. 296 (48,8%) se complicaron, y fue mayor en el segundo periodo (52,5% frente a 48,1%), al igual que las complicaciones mayores (20,8% frente a 14,2%, p = 0,033), sin diferencias en complicaciones menores (33,9% frente a 31,8%, p = 0,765). 190 (31,3%) pacientes presentaron disfagia recurrente, estable en ambos períodos. La migración aumentó con el tiempo (de 13,1% a 18,2%, p = 0,09). El evento adverso menor más frecuente fue dolor, que aumentó con el tiempo (de 24,9% a 33,95%, p < 0,01), y los factores asociados fueron quimiorradioterapia, ausencia de fístula y carcinoma de células escamosas. El reflujo ácido disminuyó en el segundo grupo (p = 0,038). El 12% de pacientes requirieron otra intervención para alimentarse. No se impactó la sobrevida con el tiempo y uso de stents.
Conclusiones: los stents son una alternativa en la disfagia maligna no quirúrgica, aunque la disfagia recurrente no ha disminuido con el tiempo. Las complicaciones menores relacionadas con el stent van en aumento, asociadas a la implementación de la quimiorradioterapia.

Introducción: la ingesta de cuerpos extraños es un problema médico frecuente, especialmente en el servicio de urgencias. Existen algunos estudios pequeños que describen las experiencias al respecto.
Materiales y métodos: estudio descriptivo, retrospectivo, en el cual se incluyó a pacientes con sospecha de ingesta de cuerpos extraños, ingresados al servicio de gastroenterología y endoscopia digestiva de La Clínica Universitaria Colombia, entre enero de 2007 y agosto de 2020.
Resultados: la edad de ocurrencia del evento se presentó en pacientes desde los 18 hasta los 95 años, y la edad promedio fue de 45 años. Los cuerpos extraños ingeridos y encontrados fueron variables; los más frecuentes fueron la ingesta de espinas de pescado, que representó el 64,11% de los casos, seguido por la ingesta de huesos de pollo y la impactación alimentaria. Un 38% de los pacientes requirieron la extracción de cuerpo extraño y la herramienta usada con mayor frecuencia fue la pinza de cuerpo extraño. La localización principal fue el esófago, en el 12,53% de los casos, seguido por la cricofaringe, en el 11,18%, y la hipofaringe, en el 10%.
Conclusiones: la Clínica Universitaria Colombia es un sitio de referencia de una gran cantidad de urgencias en gastroenterología debido a su alto nivel tecnológico y al gran recurso humano que requieren. Este trabajo representa probablemente la cantidad más grande de pacientes con este motivo de consulta, razón por la que se diseñó este estudio descriptivo retrospectivo, que muestra las características demográficas, los tipos de cuerpo extraño, los hallazgos radiológicos y endoscópicos y las complicaciones asociadas, que son de utilidad para tener un conocimiento más real de esta patología.
No rotación intestinal, hallazgos por imagen en el espectro de malrotación: reporte de caso
Authors: Rojas Borda Andres Felipe , Fajardo Pardo Patricia , Senejoa Nuñez Nairo Javier , Prada Andrés
Published: December 2023

La no rotación intestinal es una anomalía del desarrollo embrionario poco frecuente con una incidencia reportada de hasta el 0,5 % en autopsias. El diagnóstico puede ser tardío dado el curso asintomático, por lo que se convierte en un hallazgo incidental. El objetivo de este estudio es dar a conocer las características por imagen más comunes para familiarizar a los lectores con esta patología.
Se presenta el caso de un paciente de 73 años que consultó por dolor en la región inguinal derecha asociado a sensación de masa. En el examen físico no hubo hallazgos significativos. Se solicitó una tomografía abdominal con contraste como método de estudio y se identificó una inversión de la relación entre la arteria y vena mesentérica superior con la presencia de ciego, apéndice y válvula ileocecal en el flanco izquierdo y mesogastrio. Adicionalmente, se observó un desplazamiento de asas intestinales delgadas hacia el hemiabdomen derecho.
Diagnóstico de enfermedad celíaca luego del inicio de medicación antituberculosa; reporte de un caso
Authors: Mesa Zuluaga Maria Alejandra , Franco Henao Johnnatan , Bedoya López Maria Alejandra , Orejuela Erazo Janine Andrea
Published: December 2023

Se presenta el caso de un paciente joven, proveniente de Argentina y residente de un área rural, sin ningún antecedente médico a resaltar. Consultó al servicio de urgencias después de un trauma cerrado de tórax y durante los estudios de trauma se encontraron imágenes compatibles con tuberculosis pulmonar, diagnóstico realizado de manera incidental.
Luego del inicio de tratamiento presentó síntomas gastrointestinales dados por diarrea, dolor abdominal y pérdida de peso, lo que inicialmente se consideró un efecto adverso al tratamiento con rifampicina/isoniazida/pirazinamida/etambutol (RHZE). Al completar la primera fase del tratamiento y suspender la medicación mejoraron los síntomas, además de que las baciloscopias fueron negativas.
Posteriormente, llamó la atención la gravedad de los síntomas, por lo que se realizaron paraclínicos adicionales con resultados a favor de diarrea malabsortiva; teniendo en cuenta la procedencia del paciente y el hecho de que basaba su dieta en productos que él mismo cultivaba, sin haber exposición previa al gluten. Se sospecha enfermedad celíaca, y se obtuvieron anticuerpos y resultados en la biopsia compatibles con esta entidad. Al revisar la asociación de inicio de síntomas con el uso de tratamiento de RHZE/piridoxina, se observa que estos medicamentos pueden tener excipientes a base de trigo, lo que explica el empeoramiento de los síntomas, no por efectos adversos gastrointestinales del antibiótico sino por sus excipientes.
Finalmente, se analizó el caso, se descartó tuberculosis y se suspendió el tratamiento, redirigiendo el esfuerzo terapéutico hacia la recuperación del estado nutricional del paciente. Posteriormente, no se registran otros ingresos hospitalarios.
Lipoma gigante submucoso de colon derecho expulsado de manera espontánea por vía rectal: reporte de caso.
Authors: Hernández Sampayo Faruk de Jesús , Montes Arcón Pablo Salomón , Blanco Pertuz Paola , Perez Mingán Gloria Caterine
Published: December 2023

Los lipomas colónicos son tumores benignos que se originan en el tejido mesenquimal y se consideran el segundo tumor benigno más común en el colon, después de los pólipos adenomatosos. Tienden a afectar más a mujeres y su localización más frecuente es el colon derecho. Por lo general, estos lipomas no presentan síntomas, pero cuando alcanzan un tamaño considerable pueden causar manifestaciones. También pueden dar lugar a complicaciones como obstrucción, intususcepción y perforación.
Dado que sus características radiológicas son similares a la grasa, pueden ser visualizados mediante tomografía computarizada, aunque el diagnóstico definitivo se realiza mediante colonoscopia, donde se observa una masa grasa con forma ovalada y capacidad elástica. Las lesiones pueden ser extirpadas endoscópicamente o quirúrgicamente. La expulsión espontánea de un lipoma por vía rectal es rara y su mecanismo aún no está completamente comprendido. Aunque la literatura establece un punto de corte de 2 cm para decidir entre resección endoscópica o laparoscópica, la primera está en aumento y puede ampliar este límite. En casos grandes, como el reportado en este artículo, se recomienda una resección quirúrgica. Este caso particular se destaca por ser el lipoma de colon más grande reportado hasta ahora (13 cm) expulsado espontáneamente.
Drivers of Future Extratropical Sea Surface Temperature Variability Changes in the North Pacific
Authors: Gunnarson Jacob L , Stuecker Malte Fabian , Zhao Sen
Published: December 2023

Under anthropogenic warming, future changes to climate variability
beyond specific modes such as the El Niño-Southern Oscillation (ENSO)
have not been well-characterized. In the Community Earth System Model
version 2 Large Ensemble (CESM2-LE) climate model, the future change to
sea surface temperature (SST) variability is spatially heterogeneous. We
examined these projected changes (between 1960-2000 and 2060-2100) in
the North Pacific using a local linear stochastic-deterministic model,
which allowed us to quantify the effect of changes to three drivers on
SST variability: ocean “memory” (the SST damping timescale), ENSO
teleconnections, and stochastic noise forcing. The ocean memory declines
in most areas, but lengthens in the central North Pacific. This change
is primarily due to changes in air-sea feedbacks and ocean damping, with
the shallowing mixed layer depth playing a secondary role. An eastward
shift of the ENSO teleconnection pattern is primarily responsible for
the pattern of SST variance change.
AÇÕES FAVORÁVEIS AO ENSINO ENVOLVENDO ARGUMENTAÇÃO E REFLEXÕES MANIFESTADAS POR LICENCIANDAS NO CICLO PEDAGÓGICO
Authors: Rochelle Souza André Roberta , Santos Raquel , Ibraim Stefannie de Sá
Published: December 2023

Nesse artigo, discutimos as ações favoráveis ao ensino envolvendo argumentação e reflexões manifestadas por licenciandas ao vivenciarem um ciclo pedagógico (planejar-ensinar-refletir) relacionado ao ensino de química envolvendo argumentação. Para isso, utilizamos dados provenientes de um arquivo texto de planejamento, gravações de duas aulas conduzidas pelas licenciandas, gravações das reuniões de grupo ao longo do processo formativo, dois questionários pré e pós aula e uma entrevista. As ações foram identificadas a partir de um conjunto de 27 ações favoráveis ao ensino envolvendo argumentação e a análise das reflexões ocorreu a partir da identificação de elementos enfatizados pelas licenciandas. A análise do ciclo pedagógico vivenciado pelas licenciandas indica que elas mobilizaram conhecimento teórico-prático sobre argumentação, uma vez que conseguiram elaborar aulas que poderiam engajar os estudantes nos processos argumentativos. Entretanto, na dimensão prática, elas enfrentaram dificuldades em promover a argumentação, principalmente, entre os estudantes, resultando na ênfase de ações de Suporte. Como implicação, ressaltamos as limitações de, em contexto de formação inicial, incentivarmos apenas a produção de planos de aulas envolvendo argumentação, ou ainda, a análise de planejamentos como estratégias para avaliar os conhecimentos relativos à argumentação de licenciandos, e a necessidade de criarmos oportunidades para que os licenciandos possam planejar e conduzir situações reais de ensino, interagindo com estudantes reais.
Uganda’s Debt Sustainability: Testing The Efficacy of Debt Overhang Theory
Authors: Musiita Benjamin , Kijjambu Fredrick Nsambu , Katarangi Asaph Kabuura , Kahangane Geoffrey , Akampwera Sheila
Published: December 2023

The primary objective of this paper is to discern the impact of key economic variables, including primary balance, real interest rate, GDP growth rate, real effective exchange rate, and current account balance, on the long-term and short-term sustainability of the country's debt. Drawing on an array of econometric analyses within the Auto Regressive Distributed Lag framework, the study establishes that a fiscal surplus and sound management positively influence debt sustainability in the long run. However, it reveals that higher real interest rates pose challenges, leading to increased debt loads. While GDP growth's impact remains inconclusive, a fluctuating real effective exchange rate and the influence of the current account balance on debt dynamics emerge as crucial determinants. The study recommends a cautious fiscal approach, interest rate management, economic growth stimulation, exchange rate stability, and a focus on achieving and maintaining current account surpluses as pivotal strategies for ensuring Uganda's long-term debt sustainability. Nonetheless, the study acknowledges limitations related to sample size and endogeneity, encouraging further research to enhance generalizability and address potential omitted variables.

News Media Coverage of Snakebite Incidence in Nepal during 2010–2022
Authors: Pandey Deb P
Published: December 2023

Background: Despite snakebite being a medical emergency, it is still a neglected health issue in Nepal. Further, there exists gap of knowledge on snakebite epidemiology. Therefore, an analysis of incidence of snakebites reported in news is essential to understand snakebite epidemiology in Nepal and fill up existing knowledge gap in some extent. Objectives: We aimed analysing incidence of snakebites reported in the news media to know whether news-based incidence of snakebite is comparable to the similar incidence reported most comprehensively by Nepal Government, know the snakebite distribution patterns across its geo-climatic regions, provinces, and districts, understand supra-annual variations of snakebite incidence, and measure association between incidences of snakebites with the respective districts’ human population density. Methods: We retrospectively searched and analyzed incidence of snakebites reported in news articles published between 2010 and 2022. Using line graphs and plotted maps, we compared the annual patterns of snakebites with the national data of snakebites reported by Department of Health Services of Nepal Government. Further, we used non-parametric inferential statistics to know representativeness of our dataset and association of snakebite incidence with population density of snakebite prone districts. Results: Snakebites were reported from 53 out of 77 districts of Nepal. People inhabiting 50 out of 53 districts were affected by snakebite envenoming (with 11% of collective envenoming rate) that resulted in deaths of people inhabiting 43 districts (with 15% of collective case fatality rate). The most of envenomings and deaths occurred in the lowlands of Nepal along the northern border of India. We deemed at least 10,339 snakebites, 2,113 envenomings, and 101 deaths annually in Nepal. Conclusions: The incidences of snakebites were high in flood affected areas, terai regions as well as some districts in the hills and mountains. Therefore, improvement of the snakebite risk map released by Nepal Government is essential to ensure prevention and control of snakebite envenoming in these high affected areas. Inclusion of urban areas in terai regions of this country is essential while designing the next more representative community-based study

Endodontic treatments techniques for immature necrotic teeth include: surgical endodontics, apexification, and singlevisit MTA plug. Regenerative endodontic therapy (RET) is a newer concept that involves restoring the pulp-dentin complex in an infected tooth with an open apex. The aims of this paper were to evaluate RET of immature permanent teeth using biological scaffold and the distinctions between them, with a focus on their ease of manipulation and regenerative potential.
Hepatokines as Biomarkers of Obesity-Associated Liver Pathophysiology: Deciphering Advances in Basic and Clinical Aspects
Authors: SM Ishtiaq
Published: December 2023

Hepatokines are specialized secretory proteins of the liver that play pivotal role in regulation of metabolic homeostasis as well as ensure crosstalk of liver to other organs. In recent years, the correlation of hepatokines and hepatic diseases has been exhibited, positively. Several stimuli, particularly hepatic steatosis provoke dysregulation in metabolic homeostasis and subsequently, pathogenesis of liver diseases that influence expression and release of hepatokines. In this review, we have interlinked the association of hepatic steatosis, a hallmark of obesity, to liver and liver-derived hepatokines. Furthermore, we summarized briefly the impact of several etiologically and epidemiologically important hepatokines, including Fetuin-A, fibroblast growth factor-21 (FGF-21), selenoprotein P, sexual hormone binding globulin (SHBG), angiopoietin like 4 (ANGPTL4) and leukocyte cell-derived chemotaxin (LECT2), in health and disease. Such hepatokines could serve as non-invasive biomarkers of early stages of liver pathogenesis and might contribute in improving patient safety profile for screening purposes and expediting drug development.

Financing management has become a very important requirement in organizations or companies, including in the world of education. With good financing management, accountability and transparency in financial management will be achieved. Utilization of technology-based information systems in school financing management will greatly facilitate school work, and will even lead to increased public trust. Using a qualitative descriptive research approach, through an interview process with the principal, vice principal and school treasurer, as well as documentation, it was found that the government had made a good reporting system for School Operational Assistance (BOS) funds through the ARKAS application. The web-based application is used by both public and private schools. SD Muhammadiyah 7 Bandung as a private school that relies heavily on public trust, has developed an integrated information system through the SIMUTU application, but it is not yet 100% integrated so it is still equipped with separate financial reporting using the excel program and printing paper documents, especially for the audit process internally carried out by the foundation. The process of planning, implementing, monitoring, reporting and accountability, as a cost management process, has been well managed. This is thanks to the role of the Muhammadiyah foundation, through the Bandung City PDM, which has implemented strict monitoring and evaluation of financing.

Geopolymer-based industrial waste as red mud (RM) was successfully obtained in the presence of different loadings of rice husk ash (RHA). During the preparation, the added amounts of RHA in the geopolymer composition were varied from 10 to 50 % when the mass ratio of binder solution (Na2SiO3) and activated alkali-metal solution (NaOH 7 M) were 2.5 and the curing condition was fixed at 333 K within 24 h. For characterization, the surface morphology was evaluated by scanning electron microscope (SEM) equipped with the energy-dispersive X-ray, which detected the distribution of elements before and after the geopolymerization. To indicate the formation of geopolymer, Fourier–transform infrared spectroscopy (FT-IR) was used. The effect of the loading amounts of RHA on the Brunauer–Emmett Teller (BET) surface area value and Barrett–Joyner–Halenda (BJH) pore size of the obtained geopolymers were determined using a nitrogen gas adsorption instrument. In the bromocresol-green (BG) adsorption performed at pH 2, the higher addition of RHA in the geopolymer composition enhanced the adsorption capacities within 180 minutes. In addition, the adsorption behavior of the mixed geopolymer to BG fits well the Langmuir model, indicating that the adsorption occurs on the homogeneous monolayer surface of geopolymer. From this study, the RHA could be a natural potential filler to improve the BG-uptake of RM-based geopolymer in wastewater treatment.

Understanding the Barriers and Facilitators to Help-Seeking in Irish Equestrian Sport
Authors: Tobin Georgia , Losty Ciara
Published: December 2023

Equestrian media has highlighted an interest in the impact of mental health on performance and help-seeking behaviours. Due to the dearth of research into equestrian sports, this study aimed to understand rider mental health in equestrian sport and identify the barriers and facilitators to help-seeking among equestrian athletes. Seven equestrian athletes participated in semi-structured interviews about their experiences with mental health and the currently available services. The themes generated for riders’ understanding of mental health were multidimensional and cost. The themes for barriers were influences and education. Consequently, the facilitators of seeking help were strength and guidance. The findings support previous studies among jockeys and other athletic populations. Implications for this research highlight the potential for mental health literacy programmes and increased services. Further recommendations for future research suggest examining the current levels of mental health literacy and the differences experienced between disciplines.

La Educación está en constante búsqueda de la calidad educativa, por este motivo se han indagado diferentes maneras para cambiar la educación tradicional, al hacer uso de nuevas estrategias didácticas en las que se incluye la utilización de herramientas tecnológicas. Ahora bien, para la enseñanza del área de matemáticas en la actualidad se trata de salir de lo convencional; por esto, los docentes han visto la necesidad de emplear software educativo, entre los cuales se encuentra el Software Geogebra para la enseñanza de diversas temáticas, las cuales deben ser abordadas de acuerdo al grado en el que los estudiantes se encuentran. El desarrollo de este proyecto tiene como propósito principal crear una estrategia didáctica por medio del software Geogebra para la enseñanza de los polígonos en estudiantes de cuarto grado. Para llevarlo a cabo se requirió hacer uso de un enfoque de investigación mixto porque de esta forma fue posible recolectar toda la información necesaria para darle cumplimiento a los objetivos planteados y así dar una solución a la problemática abordada en el estudio. De igual forma, se tuvo en cuenta una triangulación recurrente que permitió vincular métodos cualitativos y cuantitativos para cumplimiento de los objetivos establecidos. La investigación se realizó con la participación de 31 estudiantes a quienes se les aplicó un test con preguntas abiertas para realizar la prueba diagnóstica, el cual permitió identificar las fortalezas y falencias que tenían los estudiantes con respecto a la temática de los Polígonos. Además, se realizó observación participante para de esta manera poder llevar a cabo las diferentes actividades para la enseñanza de los polígonos y una entrevista semiestructurada. Los resultados arrojaron que existe en primera instancia apatía por la asignatura que se refleja en los resultados académicos de los estudiantes. Al hacer un análisis de los resultados del pre-test se puede decir que existen deficiencias en cuanto a la temática porque una gran mayoría de los estudiantes no obtuvieron resultados favorables y presentan deficiencias en la identificación de las propiedades de los polígonos, pero estas falencias encontradas se lograron mejorar después de realizar actividades didácticas haciendo uso del software Geogebra, ya que así se evidenció en los resultados del postest superan de manera significativa a los del pre-test y los estudiantes desarrollaron habilidades para la identificación de polígonos y sus propiedades manifestando que las actividades desarrolladas con el software fueron divertidas y de aplicabilidad al contexto en el que se encuentran.

Published: December 2023

Innovation in the learning technology field to facilitate the activities of students and educators in the learning process is the task and responsibility of the Learning Technology Developer (Pengembang Teknologi Pembelajaran/PTP). This research aims to (1) describe and analyze the role of PTP as a facilitator in online learning during the Covid-19 pandemic and (2) describe PTP products in online learning during the Covid-19 pandemic. The research method used is descriptive qualitative. The research results show that PTPs, as facilitators, must be creative and innovative in developing learning models, media, and applications, collaborating with other professions, and increasing existing competencies related to cutting-edge technology and media. PTP must prove its performance through real work that can be realized through appropriate learning models, media, and applications. PTP has two main areas of study: soft technology and hard technology. The products produced by PTP can take the form of ICT-based learning models, learning media, and e-learning applications.
Narratives of Resilience and Marginality: A Study of Gender and Identity in Mahasweta Devi’s Till Death Do us Part
Authors: Shikha Ms.
Published: December 2023

This research paper delves into the thematic exploration of gender identity, female resilience, and the subversion of societal norms in Mahasweta Devi's collection of translated stories, Till Death Do Us Part. The collection spans over thirty years and encompasses five stories: "The Divorce", "The Saga of Kagaboga", "The Poet's Wife", “He, said Pani”, and, “Love Story”. In these narratives, Mahasweta Devi deviates from the conventional satirical and socially-critical writing style and shows extraordinary sensitivity in the portrayal of her characters. The stories are centered on the lives of five elderly women who struggle with several challenges and societal constraints. Simultaneously, they diligently explore unconventional approaches to contest prevailing norms and masculine hegemony. This research study aims to dissect these distinctive qualities in Devi's storytelling within the context of her collection, “Till Death Do Us Part”.

Foreign experience of implementation of certain forms of public control over police activities and ways of its implementation in Ukraine
Authors: Shevchuk V.
Published: December 2023

In order to develop an effective national model of public control over police activities in general and to clarify the main aspects of interaction between the public and the police, the article analyzes the foreign experience of public control over police activities and highlights the ways of its implementation in Ukraine.

The systematic basis of the study of forms of public control over police activities in foreign countries and the methods of their implementation is the principle of selectivity, the basis of which is the study of the international experience of politically, economically, and socially successful countries (France, Great Britain, Germany, the USA, Canada, Japan) in in which the public is actively involved in police activities.

As a result of the study, separate ways of implementing foreign experience in public control of police activities were proposed, in particular, the expediency was determined: to define and normatively establish the grounds, forms and methods of involving citizens in the protection of public order in the new Law of Ukraine «On Public Participation in the Protection of Public Order», which needs development and adoption; to regulate in the Law «On the National Police» one of the forms of public control over police activities - participation of citizens on a voluntary basis in the protection of public order, detection, recording and investigation of the circumstances of commission of offenses and crimes and taking measures to eliminate the causes and conditions of their commission; to develop and adopt state and municipal programs for public participation in public order and security, which should determine effective, not formal grounds, forms and procedures for such activities, including establishing the mechanism of interaction between the police and the public in this area; to create the Association for the Support of Police Activities as a public organization created on a voluntary basis by citizens to participate in the activities of the police, including to improve the provision of police services to the population and public control over police activities.

Published: December 2023

La realidad medioambiental latinoamericana ante la actual crisis climática, ambiental y energética que amenaza la supervivencia humana, demanda atención y análisis para comprenderla. Así, el medio ambiente debe (prescriptivo) y puede (normativo) configurarse como un elemento cohesionador a partir de la definición de un regionalismo ambiental que plantee el tema como interés vital, valor común y bien público regional, ejes para su configuración como potencia normativa ambiental. En este sentido, ante la crisis del multilateralismo y las propuestas desde los enfoques de gobernanza global y regional que buscan reconocer la interacción del Estado, la sociedad y el mercado, se plantea un marco de referencia a partir de la lógica integracionista latinoamericana sustentada en la formulación de proyectos políticos regionales. Desde este referente se reconocen parte de las causas estructurales de los problemas ambientales como son sus estructuras productivas y presiones sociales que causan un impacto ambiental y su correlato. Por ende el Estado, más allá de sus capacidades en sus niveles de poder y dado su grado de fragilidad, puede y debe influir en la construcción de un regionalismo ambiental a partir de un enfoque de gobernanza regional en el que las políticas públicas medioambientales son necesarias para ser coordinadas y convergentes en un regionalismo ambiental.
Use of flexible intramedullary rods for fixation of femoral fractures in eight dogs
Authors: Church Edgar M. , Schrader Steven C.
Published: December 2023

High-density, polysulfone rods were used to repair 4 comminuted and 4 short-oblique, mid-diaphyseal femoral fractures in 8 dogs. Bony union was achieved in 2 dogs at 10 and 12 weeks after surgery. In one dog, the femoral fracture was healing when amputation of the limb became necessary because of sciatic nerve damage secondary to an ipsilateral pelvic fracture. In a fourth dog, fracture repair resulted in nonunion, despite normal clinical function at 18 months after surgery. In the remaining 4 dogs (50%), the rods failed at 3.5, 4, 6, and 22 weeks after surgery. These fractures were then stabilized by use of other methods. Although several factors may have contributed to failure of the rods, multiple autoclaving of the thermoplastic implants may have caused embrittlement and subsequent breakage.
Clinical evaluation of intertrochanteric osteotomy for treatment of dogs with early-stage hip dysplasia: 37 cases (1980-1987)
Authors: Braden T. D. , Prieur W. D. , Kaneene J. B.
Published: December 2023

Between May 1980 and May 1987, intertrochanteric osteotomy was performed on 43 hips of 37 dogs (6 bilateral procedures) with early-stage hip dysplasia, with the objectives of improving hip biomechanics and reducing discomfort. Clinical evaluation consisted of: questionnaire, and/or orthopedic examination, and/or report from owner(s) via telephone. At least 1 form of evaluation was conducted for 42 of 43 hips (98%). On the basis of orthopedic examination findings, 27 of 33 hips (84%) were functionally good or normal at postoperative month 15 (on average). On the basis of owner report, 19 of 28 hips (68%) were functionally good or normal at postoperative month 11 (on average). On the basis of questionnaire data, 17 of 24 hips (70%) were functionally good or normal at postoperative year 1. Before surgery, only 11 of 37 hips (30%) had been evaluated as functionally good or normal. Of 36 owners, 33 (91.6%) reported that they would have the procedure performed again if the circumstances were the same. From the good to excellent clinical results, we concluded that intertrochanteric osteotomy is a beneficial treatment for dogs with early-stage hip dysplasia.

Authors: Avgeris Sophia , Lothrop Clinton D. , McDonald T. P.
Published: December 2023

Plasma von Willebrand factor antigen concentration was determined in 15 dogs with suspected hypothyroidism, in 1 dog with hyperthyroidism, and in 14 euthyroid dogs. The mean ± sem von Willebrand factor:antigen concentration in hypothyroid dogs (47.1% ± 12.6%) was significantly decreased (P <0.0005), compared with that in euthyroid dogs (94.7 ± 5.6%). Four hypothyroid dogs were given thyroxine for 1 month and all 4 had an increase in von Willebrand factor:antigen concentration. The plasma von Willebrand factor:antigen concentration was 200% in the hyperthyroid dog. Seemingly, reduced concentrations of plasma von Willebrand factor:antigen can be found in dogs in association with congenital von Willebrand disease or with von Willebrand disease acquired through hypothyroidism.
