Authors: Rienties Bart , Duncan Elaine , Judd Perry , Oakley Ben , Pengel Liset H. M. , Roelen Keetie , Topley Nicholas
Published: August 2024

Background

There is widespread recognition that many transplant recipients struggle to become and remain physically active. However, some transplant recipients do undertake strenuous training and significant physical activity (PA) and participate in intensive sports.

Aim

This study sought to understand facilitators and barriers to be physically active for Transplant Athletes (TXA) compared to a group of Dutch transplantees. This explorative mixed methods study analysed race performance and interview data from TxA who participated in cycling and/or the sprint triathlon at the World Transplant Games 2023, and compared their lived experiences in terms of barriers and facilitators of PA with those of 16 transplantees in a study from the Netherlands previously published in this journal.

Methods

Using Patient and Public Involvement and engagement (PPI), race data from World Transplant Games 2023 and subsequent in-depth interviews were used from 27 TxA. A visual artefact of barriers and facilitators from the previous Dutch study was used to prompt identification and discussion of barriers and facilitators of PA. Interview data were coded by three coders.

Results

Many of the barriers to PA previously reported by Dutch transplant recipients were not shared by the majority of TxA in this study. The TxA in this study reported significantly lower physical limitations, lower fear to undertake exercise, and no comorbidity issues for TxA. Furthermore, TxA perceived they received substantial social support, had the strength to do PA, and were in control of their weight.

Conclusion

Several TxA reported a lack of understanding from medical and other professionals about the appropriate intensity of PA. An evidence-based framework of PA for transplant recipients and transplant athletes is needed for safe and appropriate PA.
Role and contribution of the nurse in caring for patients with palliative care needs: A scoping review
Authors: Moran Sue , Bailey Maria E. , Doody Owen
Published: August 2024

Background

The provision of high-quality palliative care is important to nursing practice. However, caring for palliative care patients and their families is challenging within a complex everchanging health environment. Nonetheless the caring, artistic role of the nurse is fundamental to the care of the patient and family. However, this role is currently being overshadowed by the technical and scientific elements of nursing.

Methods

A scoping review was conducted utilising Arksey and O’Malley’s framework to identify the role and contribution of nurses in caring for patients with palliative care needs. An open time period search of eight electronic databases (MEDLINE, CINAHL, Academic Search Complete, PsycINFO, EMBASE, Web of Science, Scopus and Cochrane Library) was conducted on the 8th of March 2023 and updated on the 30th of April 2024. Screening was performed independently by two reviewers against eligibility criteria with meetings between authors to discuss included papers and form a consensus. Data was extracted relating to palliative care nursing, methodology, key findings, and recommendations. The analysed and summarised data was mapped onto Oldland et al seven domains framework: (a) medical/nursing and technical competence, (b) person centred care, (c) positive interpersonal behaviours, (d) clinical leadership and governance, (e) promotion of safety, (f) management of the environment, and (g) evidence-based practice.

Results

Fifty-five papers met the criteria for this review which describes the role and contribution of nurses in caring for palliative patients across all domains of professional practice. The review found the leading areas of nurse contribution were person centred, interpersonal and nursing care aspects, with leadership, managing the environment, patient safety and evidence-based practice evident but scoring lower. The contribution of the nurse in palliative care supports a biopsychosocial-educational approach to addressing the physical, emotional and social needs of patients with palliative care needs and their families across the care continuum.

Conclusion

Nurses in palliative care engage in a wide range of roles and responsibilities in caring for patients and their families with palliative care needs. However, there remains minimal evidence on the assessment, intervention, and evaluation strategies used by nurses to highlight the importance of their role in caring for patients and their families in this area. The findings of this review suggest that the artistic element of nursing care is being diluted and further research with a focus on evidencing the professional competence and artistic role of the nurse in the provision of palliative care is required. In addition, research is recommended that will highlight the impact of this care on patient and family care outcomes and experiences.

Published: August 2024

The demand for plant-based products has increased in recent years, due to several aspects related to health and environmental consciousness. This study aimed to produce and characterize a plant-based dairy alternative dessert based on araticum pulp and chickpea extract without added sugar and fat. Three formulations were prepared: Formulation 1 (F1): 20% araticum pulp + 80% chickpea extract; Formulation 2 (F2): 30% araticum pulp + 70% chickpea extract; and Formulation 3 (F3): 40% araticum pulp + 60% chickpea extract. All formulations’ chemical composition, sensorial characteristics, viscosity, total phenolic content, antioxidant activity, and microbiological stability were analyzed during 28 days of storage at 4°C and a relative humidity of 23%. Energetic value ranged from 64 to 71 kcal/100g, and carbohydrate content from 9.68 to 11.06, protein from 3.38 to 3.04, lipids from 1.41 to 1.60, ashes from 0.53 to 0.59 and crude fiber from 0.86 to 1.34 g/100g among the formulations. The increase in the proportion of araticum pulp in the formulations reduced moisture content by 1.2 to 2.1% (F1: 84.2, F2: 83.2, and F3: 82.4), protein content by 3 to 9% (F1: 3.3, F2: 3.2, and F3: 3.0), and pH value by 5.8 to 10.7% (F1: 5.50, F2: 5.18, and F3: 4.91), and increased the TSS by 1.1 to 1.3-fold (F1: 8.36, F2: 8.98, and F3: 10.63 º Brix), total phenolics content by 1.5 to 2.0-fold (F1: 4,677, F2: 6,943, and F3: 10,112 gallic acid μmol/L) and antioxidant activity by 1.8 to 2.8-fold (F1: 1,974, F2: 3,664, and F3: 5.523). During the 28 days of storage at 4°C, the formulations F1 and F2 showed better stability of phenolic compounds and antioxidant activity; however, the formulation F3 showed acceptable microbiological quality up to 28 days of storage, higher viscosity, 8 to 16-fold higher than the formulations F1 and F2, respectively (F1: 238.90, F2: 474.30, and F3:3,959.77 mPa.s), antioxidant capacity and better scores in sensory analysis. The present study showed that the plant-based dessert elaborated with araticum pulp and chickpea extract might be considered a potential dairy alternative product with high antioxidant activity, protein content, and a viscosity similar to yogurt; however, its sensory aspects need improvement.

‘Go shake this off’: Masculinities, mental health and a moment of dance in Ted Lasso’s ‘Beard After Hours’
Authors: McGovern Cheska
Published: August 2024

In television, there is a phenomenon of unexpected dance scenes in non-dance, non-musical texts. This article expands the currently limited research on this popular screen trope. Rich in dance and musical references, Apple TV+’s Ted Lasso (2020–23) presents an unexpected moment of dance in Season 2’s departure episode, ‘Beard After Hours’ (Season 2, Episode 9). I argue that the dance performed by Coach Beard (Brendan Hunt) further unfolds the series’ exploration of masculinities and mental health by expressing and producing my original concept of ‘pleasant pessimism’. Generated from Lauren Berlant’s notion of ‘cruel optimism’, pleasant pessimism resists cruel optimism and its fantasies of an unattainable good life, establishes acceptance of reality as is and offers an alternative way of being that is, however unintentionally, transformative. Merging this concept with gender studies and dance theory (primarily Laban Movement Analysis), I demonstrate how Beard’s dance into a world of pleasant pessimism expands masculinities and advocates for mental health through the production of (self-)acceptance. Ultimately, I argue, the moment of dance achieves the good life that is always out of reach with cruel optimism.

La arquitectura en las fuentes coloniales brasileñas del tiempo de Felipe II: José de Anchieta y Gabriel Soares de Sousa
Authors: Castro Brunetto Carlos Javier
Published: August 2024

La arquitectura nació en Brasil durante la segunda mitad del siglo XVI. Mientras en Europa eran frecuentes los debates intelectuales y las discusiones en torno al arte, en estas tierras de América del Sur lo que interesaba era fortificar el territorio, combatir a los indígenas hostiles y crear un sistema complejo destinado a la explotación de las riquezas de la colonia gracias al trabajo esclavo. En ese contexto, la arquitectura no era un fin estético, sino una necesidad para cubrir la demanda de fortificaciones, iglesias y construcciones domésticas. Por ello no se redactaron textos específicos sobre cómo debía ser la arquitectura en la colonia, aunque en muchos documentos la arquitectura aparece como referencia secundaria. El paso del tiempo y el poco interés por conservar los textos antiguos, oscurecieron el conocimiento del arte de esa época. Sin embargo, bajo el reinado de Felipe II en Brasil, durante la Unión Ibérica, dos personajes, José de Anchieta y Gabriel Soares de Sousa, intervinieron como cronistas de su época. La luz que arrojan sus escritos colabora en el conocimiento del Brasil de finales del siglo XVI y la importancia que entonces tuvo la arquitectura como seña de identidad lusitana en la gigante colonia tropical.

Cabra-cega: del guión a las pantallas
Authors: Toccolini Zorzo Solange Salete
Published: August 2024

Para Di Moretti, premiado guionista brasileño, es imprescindible la presencia poética en el arte de escribir guiones cinematográficos. De acuerdo con el escritor, el buen guion es aquel que cultiva la sensibilidad humana, que debe ser su prioridad en su elaboración. Por eso, antes de ser sometido a cualquier procedimiento técnico, Moretti lo llama Guion Literario. Este trabajo visa analizar el arte presente en el texto que dio origen a la película Cabra-cega, a través de los distintos elementos que lo componen, para mostrar el estilo creativo de la escritura lanzado por Di Moretti y perfeccionado de acuerdo con varios factores por la instancia narrativa hasta el Guion Técnico y la película. Al final, el cine es el arte de la imagen y es a través de ella como Moretti piensa y escribe.

Singularidades y controversias del sistema estadístico brasileño
Authors: Reis Cardoso Sidneia
Published: August 2024

Desde el inicio de la formación del sistema estadístico brasileño, la producción y difusión de las estadísticas oficiales siempre han estado conectadas con las necesidades de conocimiento del Estado sobre sus recursos. Pero con el desarrollo de la sociedad, las estadísticas tienen otro propósito. Con el creciente volumen de la demanda de información, se llega a la fase actual en que el sistema tiene que proporcionar datos no sólo para el gobierno sino para la sociedad en su conjunto. Y esta disposición de datos tiene que ser de forma confiable, imparcial y de utilidad práctica para la sociedad. Este se convierte en el nuevo propósito social del sistema estadístico. Actualmente cuando la sociedad brasileña vive en un Estado democrático de derecho, este trabajo tiene como objetivo analizar algunos cuellos de botella que obstaculizan el cumplimiento de la finalidad social del sistema. Estos cuellos de botella están insertados en la red de relaciones entre usuarios, productores y Estado. El trabajo busca reflexionar, entonces, sobre los principales problemas que afectan a la relación de los productores con los usuarios; la integración del sistema y la coordinación; y también sobre las principales controversias con respecto a la estructura institucional del sistema estadístico.

¿Si se vende más, se cumple menos? Brasil entre la reglamentación internacional y la expansión de su industria de defensa
Authors: De Ávila Flavia , Diniz Guerra Silvestre Cristiano Armando
Published: August 2024

El aumento de la atención internacional sobre las armas ligeras ha generado varias acciones que ponen de manifiesto esta preocupación. Organizaciones multilaterales y no-gubernamentales como la ONU y Caritas siguen registrando su uso en diversas zonas de conflicto del mundo. No obstante, su regulación en Derecho Internacional Humanitario es dispersa, lo que conviene, sobre todo, a los fabricantes de armas. La industria de Defensa ha sido incentivada indiscriminadamente en Brasil, dicho incentivo aparece en la Estrategia Nacional de Defesa de 2008. Según el Small Arms Trade Survey, Brasil figura en la cuarta posición mundial en venta de armas, y, según su Ministerio de Desarrollo, Industria y Comercio Exterior, se ha producido un crecimiento del 500% en el valor de las exportaciones de este sector, pasando de US$ 109,6 millones en 2005 a US$ 321,6 millones en 2010. Esta investigación, realizada desde un abordaje cualitativo y de acuerdo con el método inductivo con carácter prospectivo, en base al análisis de contenido jurídico-documental, presenta la siguiente hipótesis: que el desarrollo de la industria de Defensa ha sido un factor que ha obstaculizado la adopción de medidas jurídicas más enérgicas para tratar la regulación de las armas convencionales, aunque Brasil hay firmado algunos tratados sobre el tema.
La militancia de la forma en Cabra marcado para morrer: distanciamiento, dispositivo reflexivo y creación de la realidad como estrategias de la segunda fase del documental de Eduardo Coutinho
Authors: Ferreira Vasconcelos Gabriel
Published: August 2024

El trabajo consiste en un análisis de las estrategias formales de Eduardo Coutinho en el documental Cabra marcado para morrer (1984). Estas estrategias marcaron la segunda fase de su carrera. En ese período, Coutinho negaba el sesgo militante de su juventud y las convenciones televisivas, en un movimiento de búsqueda de las condiciones de producción de la verdad y la super-verité de los entrevistados (Jean Rouch). En pocas palabras, esto ocurrió gracias al distanciamiento brechtiano (presencia del equipo y el dispositivo técnico de la película), un dispositivo reflexivo (por ejemplo, narración reflexiva y anti normalizadora), el rodaje continuo y la construcción de la realidad mediante la creación de hechos no naturales.

Authors: Ricci Claudia Lizandra , Passareli João Victor Goulart Consoni , Nascimento Felipe Franco , Kanashiro Glaucia Prada , da Costa Zulim Luís Felipe , Giuffrida Rogério , Andrade Silvia Franco
Published: August 2024

Background and Aim: Measuring intraocular pressure (IOP) is crucial for identifying potentially damaging changes in the eyes, including diseases as glaucoma and uveitis. This study compared intraocular pressure (IOP) measurements in cats using the Tonovet and Tonovet Plus (rebound), Tono-Pen Avia Vet (applanation), and Kowa HA-2 (Goldman’s methodology applanation) tonometers.

Materials and Methods: 55 healthy cats (108 eyes) were assessed through three distinct studies: An ex vivo experiment (10 eyes of five cats) to correlate IOP manometry and tonometry values and ascertain the correlation coefficient (r2); an in vivo study (10 eyes of five sedated cats) to contrast manometer and tonometer readings; and an outpatient clinical trial (80 eyes of 45 cats) to analyze only tonometer measurements.

Results: The r2 values observed in the ex vivo study were Tonovet (0.923), Tonovet Plus (0.925), Tono-Pen Avia Vet (0.877), and Kowa HA-2 (0.901). The IOP values in mmHg in the in vivo study were as follows: Manometer (16.1 ± 2.7), Tonovet (21.1 ± 3.6), Tonovet Plus (19.7 ± 7.2), Tono-Pen Avia Vet (17.6 ± 7.9), and Kowa HA-2 (16.8 ± 2.0). In the outpatient clinical study, the IOP values in mmHg were as follows: Tonovet (19.7 ± 6.6), Tonovet Plus (17.1 ± 5.4), Tono-Pen Avia Vet (16.3 ± 4.3), and Kowa HA-2 (14.5 ± 2.2).

Conclusion: IOP and manometry readings were strongly correlated by all tonometers. In the clinical setting, the most and least IOP measurements were recorded using Tonovet and Kowa HA-2, respectively, stressing the importance of an IOP reference table for each tonometer in feline practice.

Keywords: applanation tonometry, goldmann tonometry, intraocular pressure, ocular manometry, rebound tonometry.
Közös figyelem és teatralitás
Authors: Szabó Judit
Published: August 2024

A közös figyelem (joint attention) azt a kognitív képességet jelöli, hogy az ember képes figyelmét megosztani egy tárgy és egy (vagy több) megfigyelő között, és a többi megfigyelővel együtt tudja, hogy mindannyian ugyanazt a tárgyat figyelik. A széleskörű szakirodalom és nagyszámú neurokognitív vizsgálat alapján a közös figyelem mérföldkövet jelent a magas szintű kognitív képességek kialakulásában:
szerepet játszik a nyelv és a kommunikáció (Michael Tomasello), illetve a tudatelmélet megjelenésében (Simon Baron-Cohen). A közös figyelem eredetére vonatkozó evolúciós magyarázatokban nem alakult ki konszenzus, és az utóbbi években több olyan elmélet is napvilágot látott, amely a közös figyelem emberre jellemző összetett formájának fejlődését összefüggésbe állítja korai kulturális gyakorlatok (performativitás, rítus, hipotetikus játék) kialakulásával (Fritz Breithaupt). Jelen tanulmány ezt az elméleti felvetést követve nyújt betekintést az attikai tragédia előadási gyakorlatainak kutatásaiba, amelyek a fennmaradt szövegek alapján a közös figyelem irányításának változatos formáit azonosítják (A.C. Duncan).
Qualidade microbiológica de queijos Minas frescal não inspecionados comercializados em feiras livres na região de Bauru, São Paulo

Published: August 2024

O queijo Minas Frescal tem alta umidade e pH próximo da neutralidade, o que favorece a proliferação microbiana. É um hábito comum as pessoas adquirirem esse tipo de queijo em feiras livres, onde são vendidos sem nenhum tipo de selo de qualidade que garanta a inocuidade do produto. Salmonella spp., Staphylococcus aureus coagulase positiva e coliformes são alguns exemplos de patógenos que podem ser encontrados nesses queijos quando há manipulação excessiva, utilização de leite in natura e falhas de boas práticas de fabricação. O objetivo da presente pesquisa foi avaliar a qualidade microbiológica de queijos Minas Frescal sem inspeção sanitária, comercializados em feiras livres na região de Bauru, São Paulo, por meio da pesquisa de Salmonella spp., Staphylococcus aureus coagulase positiva e coliformes totais e termotolerantes, comparando os resultados obtidos com a legislação vigente. Amostras de trinta queijos tipo Minas Frescal foram avaliadas. As análises microbiológicas foram feitas conforme a literatura, no Laboratório de Análises Clínicas da Universidade Paulista (UNIP), Campus Bauru. Todas as amostras analisadas apresentaram ausência total de Salmonella spp. e de Staphylococcus aureus coagulase positiva. Porém, 26 das 30 amostras estavam em desacordo com a legislação vigente quanto ao número máximo permitido (NMP/g) de coliformes totais, sendo, também, detectada a presença de Escherichia coli em 36% das amostras. Os resultados mostraram que os queijos comercializados em feiras livres da região de Bauru – SP apresentam baixas condições higiênico-sanitárias e podem significar um potencial risco à saúde dos consumidores.

Los estudios muestran que en la realidad, muchas familias no participan de forma activa ni se involucran en los aspectos esenciales de la formación de sus hijos. Este estudio analiza los factores que intervienen en el proceso de participación de las familias, a la vez que se proponen una serie de propuestas didácticas para hacer con las familias en el área de Geografía e Historia.
Banchetto, vino, morte e amore in Platone
Authors: Casertano Giovanni
Published: August 2024

Questo studio tratta delle varie specie di banchetto presso i Greci, e in particolare dell’uso del vino, con un accenno al dio Dioniso. In un simposio ben ordinato, dove gli uomini riescono a comunicare tra di loro e a rafforzare i vincoli di amicizia che li uniscono, si prefigura, nei dialoghi platonici, quel simposio eterno che, nel mito, gli dèi promettono ai buoni, dopo la morte. Ci sono, nel Fedone, vari significati del termine “morte”, quello scientifico, quello psicologico e quello metaforico, ed è proprio in quest’ultimo che la morte viene associata all’amore per una delineazione della mortale immortalità che sola per Platone è concessa agli uomini.
Un enigma en el Crátilo
Authors: Bossi Beatriz
Published: August 2024

Intentaré ofrecer alguna pista con relación a la cuestión de cuál es el alcance, significado y evolución de la figura del νομοθέτης en el Crátilo. Su papel le sirve a Platón instrumentalmente para refutar, siquiera parcialmente, por una parte, el convencionalismo de Hermógenes, mediante el sutil desplazamiento desde la figura de “quien establece el uso de las palabras” (arbitrariamente) a la figura de un experto artesano que debe conocer la naturaleza de las cosas para operar correctamente. Por la otra, también le sirve para refutar el naturalismo de Crátilo, porque los forjadores de los nombres primitivos han errado al suponer una realidad exclusivamente en movimiento, y al ignorar que el lenguaje, siendo imitativo, implica la posibilidad del error. El análisis etimológico sirve para exponer cómo la mayoría de ellos han fallado, por lo que el lenguaje no es el camino para el conocimiento de la realidad, sino, a la inversa: el dialéctico, quien conoce lo que las cosas son, es el que está en condiciones de controlar que los nombres sean forjados y establecidos correctamente. Así resulta que los malos artesanos quedan descartados y el bueno, que conoce la Forma Nombre, se ha convertido al platonismo.
enigma de la dialéctica platónica y el papel de la refutación
Authors: Vallejo Campos Álvaro
Published: August 2024

El enigma de la dialéctica platónica se debe a la descripción metafórica de sus procedimientos en la República y a la oscuridad sobre el modo de alcanzar el principio superior que debe dar razón de las hipótesis o supuestos. Como no puede ser derivado deductivamente de otro anterior, algunos especialistas han asignado a la intuición un papel fundamental en su aprehensión, pero esto significaría una dualidad respecto al carácter dialógico de la dialéctica, que conllevaría una ruptura misma del método. Sin embargo, “los peldaños y trampolines” así como el descenso “a partir de las cosas que de él dependen” hablan en favor de un procedimiento netamente discursivo. Esto implica que la dialéctica justifica un supuesto sometido a discusión filosófica por medio de su inclusión en un sistema de proposiciones en las que estas deben estar conectadas de un modo coherente, es decir, sin contradicciones mutuas y en una relación deductiva de anterioridad y posterioridad. En todo este proceso no hay alusión alguna a un método intuitivo, sino una insistencia absoluta en la necesidad de dar razón y de ser capaz de defender el principio afrontando todas las refutaciones u objeciones, que es el procedimiento de donde resulta su condición no hipotética.

Neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio as potential diagnostic markers for rebleeding in patients with esophagogastric variceal bleeding
Authors: Chen Lei , Tong Cong , Zhao Xiangan , Xu Chunfang
Published: August 2024

The aim of the present study is to explore the potential prediction value of neutrophil-to-lymphocyte ratio (NLR) or peripheral blood platelet-to-lymphocyte ratio (PLR) for rebleeding in patients with esophagogastric variceal bleeding (EVB). We have enrolled 80 rebleeding patients with EVB and 113 EVB patients without rebleeding in the present study. The lymphocyte, platelet counts, the PLR, and the NLR of the candidates were calculated, and receiver-operating characteristic curve was drawn to examine whether NLR or PLR is a sensitive biomarker for distinguishing rebleeding patients from the EVB patients. We observed that NLR and PLR were all significantly increased in rebleeding patients with EVB compared with the non-rebleeding patients (p < 0.01); moreover, the area under the curve of NLR and PLR was 0.7037 (95% confidence interval [CI], 0.6281–0.7792) and 0.7468 (95% CI, 0.6793–0.8144), respectively, suggesting that NLR or PLR is a sensitive biomarker for distinguishing non-rebleeding patients from the rebleeding patients. We reported that NLR and PLR were significantly increased in the peripheral blood of patient with esophagogastric variceal rebleeding, suggesting that NLR and PLR may be potential early diagnostic and prognostic markers for the rebleeding among patients with EVB.
G protein-coupled receptor 1 participating in the mechanism of mediating gestational diabetes mellitus by phosphorylating the AKT pathway
Authors: Zhu Yanbin , Huang Shufeng , Chai Dan , Liang Lei
Published: August 2024

Gestational diabetes mellitus (GDM) is a metabolic disease that occurs during pregnancy. Herein, we investigate G protein-coupled receptor 1 (GPR1) in mediating GDM through the phosphorylation of serine/threonine kinase (AKT) pathway. Thirty pregnant SD rats were grouped into: normal pregnancy control group (NC), GDM model group, and GDM model + high-dose GPR1 antagonist treatment (GDM + Ari) group. GDM model was established, and the GDM + Ari group adopted GPR1 antagonist aripiprazole. The blood glucose level, insulin level, and insulin resistance (IR) were detected. The expression and phosphorylation of GPR1, AKT, and extracellular signal-regulated kinase (ERK) in placental tissue were detected using reverse transcription-polymerase chain reaction (RT-PCR) and western blotting (WB). The serum insulin concentration, glucose concentration, and glycated hemoglobin concentration during pregnancy in GDM group SD rats were significantly higher than those in the NC group (P < 0.05). The expression and phosphorylation levels of GPR1, AKT, and ERK in the placental tissue of SD pregnant rats in the GDM group were significantly lower than those in the NC group. Furthermore, compared with the GDM group, the expression of GPR1, AKT, and ERK in placental tissue was significantly reduced in the GDM + Ari group, while simultaneously enhancing the blood glucose level and IR level. In addition, the survival number, body weight, and malformation rate of the offspring of the GDM + Ari group were significantly improved, and there was no significant effect on the number of offspring. The expressions of GPR1, AKT, and ERK in placental tissue exhibited a significant decrease, while the glucose level and IR were observed to increase in the GDM + Ari group. Enhancing the expression of GPR1 may activate AKT phosphorylation to alleviate GDM. GPR1 could potentially serve as a novel target for diabetes treatment, offering new insights into managing GDM.

In today’s rapidly evolving digital landscape, the urgency to secure data within expansive cloud storage systems has reached unprecedented levels. Conventional remote storage methods, while widely used, are inherently vulnerable to security breaches, corruption, and tampering. Recognizing this critical challenge, a state-of-the-art protocol has emerged to address these vulnerabilities head-on. This innovative solution integrates a sophisticated binary search tree (BST) structure with elliptic curve cryptography, ensuring not only efficient data retrieval but also robust encryption mechanisms. The protocol goes further by meticulously computing secure hashing algorithm hash values to verify the integrity of files, leaving no room for unauthorized modifications or tampering attempts. A thorough comprehensive benchmarking analysis has been conducted comparing this protocol with established techniques such as Rivest, Shamir, Adleman encryption and doubly linked list-based index table structures. The findings reveal that the proposed protocol outperforms these conventional methods, showcasing superior security features and computational efficiency. Remarkably, the proposed method reduces overheads by an impressive 5%, making it a highly favorable choice for both businesses and academic institutions. This marks a significant advancement toward fortified data security in cloud environments, contributing substantially to the ongoing discourse on secure data storage and management.

Neste artigo apresentamos um estudo comparativo das operações linguísticas realizadas na primeira versão e na reescrita de relatórios de estágio de alunos do último ano do Curso de Letras, habilitação Português/Literatura de uma universidade federal. Ancorados nos pressupostos de Vázques (1977) sobre a filosofia da práxis e na literatura que trata do processo de escrita e de reescrita textual, realizamos a análise contrastiva tanto em relatórios de estágio que atingiram os objetivos propostos quanto naqueles que não atingiram. Os resultados evidenciam a existência de conflitos entre embasamento teórico e capacidade de reflexão sobre a prática de sala de aula à luz das teorias estudadas. Evidenciam também a importância do aluno-autor se colocar na posição de leitor de si mesmo e do professor orientador na posição de leitor interessado em investigar como os alunos constroem sua escrita e suas reflexões teórico-práticas.
Using Current Events to Engage Students in Scientific Discourse
Authors: Minbiole Julie E.
Published: August 2024

Instructors from K–16 incorporate current events and contemporary media in their courses in a variety of ways and with different educational objectives. Here, I present strategies for selecting and framing current events in high school and undergraduate biology courses and an example assignment, all explicitly tied to science practice skills and utilizing coursework to advance students’ science literacy and participation in the discourse. In this way, current events activities become a core part of the course experience, rather than an “extra” investment of planning and course time requiring trade-offs of instructional time devoted to other topics.

The risk of infection by parasitic agents in contaminated vegetables is greater when the characteristics of the sale stalls in markets and the hygiene of street vendors is poor. This study aimed to determine the prevalence of parasitic stages and identify the genera/species found in vegetables sold in the main markets of the city of Chiclayo, Peru. In total, 600 vegetable samples were analysed, 75 for each species: lettuce, green onion, celery, radish, cabbage, coriander, parsley and spinach. Using wet mounting, it was determined that 51% (95%CI 47-55) of the samples contained parasitic stages. Entamoeba spp, Giardia spp, Balantidium coli, Taenia spp, Enterobius vermicularis, Ascaris spp, Trichuris spp, Toxocara spp, and Hymenolepis nana were identified. The proportion of protozoan cysts/oocysts was higher than helminth eggs. Lettuce and green onion were the vegetables with the highest presence of parasitic stages. It is concluded that the vegetables sold in the main districts of Chiclayo are highly contaminated with parasitic stages.

Published: August 2024

A 10-year-old female canine patient was admitted to the consultation. The clinical examination revealed a protrusion with soft and mildly painful content at the level of the hypogastrium in the left mammary gland, plus an inguinal hernia. During the physical examination, vulvar hypoplasia, protrusion of the clitoris and seropurulent discharge. Diagnostic imaging tests such as digital radiography and ultrasonography were used. It was decided to perform exploratory laparotomy where intestinal necrosis resulting from imprisonment was determined. Likewise, true hermaphroditism could be determined due to the presence of a testicle retained in the abdominal cavity. Enterectomy was performed, and simultaneously ovary hysterectomy and orchiectomy were performed. The patient recovered satisfactorily from surgery and progressed favorably.

Published: August 2024

The aim of this study was to determine the prevalence of Ehrlichia spp, Anaplasma spp, Dirofilaria immitis and the presence of Borrelia burgdorferi in canines from the city of Guayaquil. Blood samples were taken from 220 dogs and analysed using the ELISA technique (Snap 4Dx Plus, Idexx®). In 120 of these dogs the presence of ectoparasites was determined and their blood samples were also analysed by smears to compare the results with those obtained by ELISA. The results were analysed using Chisquare and Fisher’s exact test to determine the risk association and the influence of risk factors (age, sex, and area) based on the Odds Ratio. The Kappa test was performed to determine the agreement between the tests used. The prevalence of Erhlichia spp was 75.4% (166/220), Anaplasma spp 22.8% (49/220), D. immitis 2.3% (5/220) and null for B. burgdorferi. Coinfection of Erhlichia spp and Anaplasma spp (20.9%) and Erhlichia spp and D. immitis (2.3%) was found. No association (p>0.05) was found between these pathogens with respect to age, sex or the area where the animals live. The level of concordance of the Kappa index between the ELISA technique and the blood smear was acceptable (Erhlichia spp = 0.79; Anaplasma spp = 0.91), but a higher sensitivity in the ELISA method.

Published: August 2024

Penaeus vannamei aquaculture is an important productive sector in Ecuador; however, this sector is still deficient in identifying and managing health problems, mainly in the larval stage. For eight weeks, the microbial load was evaluated with respect to total heterotrophic bacteria and Vibrio spp in the inlet water, treated water, and production tanks of three laboratories in the Canton of Sucre, province of Manabí. Additionally, a survey was carried out on laboratory management and the application of basic health measures. Average values of 7 x 106 CFU mL-1 for heterotrophic bacteria and 4 x 102 CFU mL-1 for Vibrio spp were obtained. No significant differences (p>0.05) were found for each type of bacteria between the sampled points across laboratories or between different points in the same laboratory. Vibrio spp values were within the recommended values, while heterotrophic bacteria exceeded the reference values. The results of the surveys expose the lack of training programs on health and/or biosecurity issues.

Published: August 2024

Cardiovascular illnesses have the potential to result in the development of heart failure (HF), a fatal phenomenon that can manifest in various forms, making diagnosis and treatment a complex challenge. The current therapeutic approaches for patients with HF are established according to their clinical presentation and echocardiographic measurements. Nevertheless, this method fails to consider the underlying pathophysiological mechanisms involved. Hence, the utilisation of natriuretic peptides (NPs) in conjunction with clinical assessment and echocardiographic outcomes as markers for selecting the optimal treatment for HF, considering the underlying pathophysiology of the condition and current strategies, will contribute to the formulation of future guidelines aimed at enhancing the management of HF. This review study critically analyses the most recent scholarly studies pertaining to natriuretic peptides and their therapeutic implications in the management of both acute and chronic HF. Moreover, we touch up on the clinically available NPs based medication and challenges comes with them in the management of HF. By evaluating the potential of these biomarkers, the study aims to provide a critical analysis of their value in outlining future therapies for HF. The findings are expected to contribute to improving patient outcomes and enhance the quality of provide care for HF patients.
