ABSTRACT: This study adopted a more macroscopic perspective to focus on the issue of rural poverty in China. By selecting indicators reflecting various levels of poverty recurrence, considering risk factors across multiple dimensions, and employing advanced methods, we constructed a novel China Rural Poverty Recurrence Risk Index. We utilized a Markov switching model to delve into the mechanisms of poverty recurrence. Building upon this foundation, we developed an advanced poverty recurrence risk early warning system using a convolutional neural network-long short-term memory (CNN-LSTM) model. The system is optimized through mechanism-based predictions to better capture the dynamic changes in poverty recurrence. Empirical results demonstrated that the integrated dynamic monitoring and early warning system have significantly effective outcomes in addressing the recurrence of rural poverty.

ABSTRACT Objective: The aim of this study was to investigate the contextual factors associated with the quality of life (QOL) of Brazilian children aged 0–12 years during the strict period of social isolation. Methods: This observational cross-sectional study was conducted between July and September 2020 using an online questionnaire on QOL-related family factors and the Pediatric Quality of Life Inventory (PedsQL™). Results were analyzed by multinomial logistic regression analysis. Results: The sample had 849 children, mostly from the South Region of Brazil (75%), white (83%), with typical development (79%), sedentary (68%), using screen (85%) for >3 h/day (44%). Their mothers were their main caregivers (90%). The following variables were significantly associated with high scores of QOL: typical health status (OR 2.38; 95%CI 1.60–3.55; screen time ≤2 h/day (OR 1.62; 95%CI 1.17–2.24); social distancing considered as “easy” (OR 1.67; 95%CI 1.20–2.32), and stimulation of the child by the family (OR 1.93; 95%CI 1.08–3.45). Conclusions: This study indicates that the family context can influence children’s QOL, especially during the COVID-19 pandemic and home environment reorganization.

ABSTRACT Purpose: To evaluate the predictive value of initial intraocular pressure difference of the detached and fellow eyes of patients with complex rhegmatogenous retinal detachment on postoperative persistent ocular hypotony. Methods: This retrospective observational study included 538 eyes of 538 unilateral complex rhegmatogenous retinal detachment patients with a proliferative vitreoretinopathy grade of C-1 or higher, treated with silicone oil endotamponade following pars plana vitrectomy. The patients were divided into Group A (patients having silicone oil removal without ocular hypotony; n=504) and Group B (patients with persistent ocular hypotony following silicone oil removal [n=8, 23.5%] and with retained silicone oil [n=26, 76.5%] due to the risk of persistent ocular hypotony; total n=34). Ocular hypotony was defined as an intraocular pressure of <6 mmHg on two or more occasions. Patients’ demographics, including age, sex, and follow-up time, and ocular characteristics, including ocular surgical and trauma history, initial and final best-corrected visual acuity, intraocular pressure and initial intraocular pressure difference of the detached and fellow eyes, and anatomical success rates and postoperative complications, were retrospectively collected from the electronic patient files. Results: The initial intraocular pressure was significantly lower in the detached eyes of Group B than in Group A (8.3 ± 3.5 vs. 12.9 ± 3.3, p<0.001). Also, the initial intraocular pressure difference was significantly higher in Group B than in Group A (8.9 ± 3.2 vs. 2.2 ± 2.7mmHg, p<0.001). The receiver operating characteristic curve analysis showed that the cutoff value of the initial intraocular pressure difference was 7.5mmHg for the risk of persistent ocular hypotony. The most influential factors on postoperative persistent ocular hypotony in the binary logistic regression analysis were the initial intraocular pressure difference and the need for a retinectomy. Conclusion: In eyes with complex rhegmatogenous retinal detachment treated with pars plana vitrectomy and silicone oil tamponade, the initial intraocular pressure difference could be of value in predicting postoperative persistent ocular hypotony and could guide surgeons on the decision of silicone oil removal.

ABSTRACT Purpose: Although Brazil has a high prevalence of retinoblastoma, there is a lack of epidemiological data on the disease. Thus, in this study, we aimed to evaluate the epidemiological profile of patients diagnosed with retinoblastoma in the ophthalmology department of a pediatric tertiary referral hospital in Ceara, Brazil. Methods: A descriptive and cross-sectional study was conducted by retrospectively analyzing the clinical and socioeconomic data from the medical records of pediatric patients followed-up at the hospital between 2007 and 2021. Retinoblastoma was diagnosed on the basis of a fundoscopic or histopathologic examination. Results: The data of 105 patients were included in the study, and the mean patient age at the time of diagnosis was 1.7 years. Most of the patients were women (50.5%) and hailed from rural areas (57.4%), which was associated with a higher tumor stage. Of the 150 patients, 57.1% initially presented with leukocoria. Ocular hyperemia was associated with more advanced stages of retinoblastoma (p=0.004). Bilateral involvement was observed in 25.7% of the patients and at a significantly younger age (p=0.009). The presence of retinal detachment, vascularized lesions, and vitreous seeds significantly increased the likelihood of requiring enucleation. Discussion: This study presents an epidemiological description of retinoblastoma in Brazil, which highlights the significance of early detection. Delayed diagnosis is associated with a poorer visual prognosis and higher mortality rate, particularly in patients with unilateral disease. Risk factors for a more severe disease were retinal detachment, vascularized lesions, and vitreous seeds. The correlation between histopathological features and clinical outcomes was limited. Conclusion: Further studies are required to assess the influence of ocular hyperemia, fundoscopic assessment, and histopathologic findings on the prognosis of retinoblastoma. Moreover, it is critical to devise interventions to reduce the time-to-diagnosis in rural areas.

ABSTRACT Objective: To describe cases of acute kidney injury (AKI) in children diagnosed with COVID-19, associated risk factors, clinical aspects and outcome of cases. Methods: Retrospective study, carried out in a pediatric hospital between March 2020 and September 2021, with patients with COVID-19 who were diagnosed with AKI, studying information present in medical records such as comorbidities, age, gender and use of nephrotoxic medications. Results: We studied 40 cases, and male individuals were significantly more affected (62.5%; p=0.025). AKI was a severe complication of COVID-19 infection, with 100% of the sample requiring admission to the Intensive Care Unit and 22.5% dying. The most prevalent comorbidities analyzed in this study were epilepsy, cerebral palsy and heart disease. Most patients were classified according to Kidney Disease: Improving Global Outcomes (KDIGO) criteria as KDIGO 1 (42.5%), and required orotracheal intubation (67.5%). The frequency of use of nephrotoxic medications and need for dialysis was low, with percentages of 35 and 17.5%, respectively. Among the children who died, 70.4% had some comorbidity and 88.8% received invasive ventilation. Conclusions: AKI in children with COVID-19 infection is associated with severe conditions. Despite the severity, most patients were discharged alive from the hospital.

RESUMO Este estudo foca no desempenho de vacas para produção de carne, criadas nos pântanos do Paraguai, examinando cinco genótipos bovinos; Brahman, Brangus, Nelore, bem como duas raças locais em risco de extinção. O principal objetivo é identificar e classificar variáveis fenotípicas que incluem variáveis sanguíneas, clínicas, de pelagem e saúde, demonstrando ligação causal com o peso vivo das vacas analisadas. Inicialmente, foram identificadas correlações elevadas entre diferentes variáveis incluídas neste estudo, e, então, utilizando técnicas avançadas de aprendizado de máquina e a aplicação de explicações aditivas de Shapley (SHAP), foi proporcionado um entendimento mais profundo dos fatores fortemente associados à adaptabilidade nestes ambientes, e, portanto, o respectivo desempenho zootécnico. A associação entre o componente genotípico bovino ligado à estação do ano mostrou ser o fator influente mais predominante sobre o peso vivo bovino. Variáveis como comprimento do pelo, hematócrito, fosfatase, fósforo, creatina phosphokinase, creatinina, proteína, cortisol, cálcio e a presença de endoparasitas foram destacadas, demonstrando sua importância hierárquica para a seleção animal. Os modelos de ML são ferramentas eficazes para estabelecer hierarquias de relevância em multivariáveis fenotípicas complexas, o que é crucial em programas de melhoramento genético em diferentes espécies zootécnicas, bem como em ambientes especiais e específicos, como os pântanos. carne Paraguai bovinos Brahman Brangus Nelore extinção sanguíneas clínicas saúde analisadas Inicialmente então SHAP, SHAP , (SHAP) portanto zootécnico pelo hematócrito fosfatase fósforo phosphokinase creatinina proteína cortisol destacadas animal complexas zootécnicas específicos (SHAP

ABSTRACT This study focuses on the performance of cows for meat production raised in the wetlands of Paraguay, examining five cattle genotypes: Brahman, Brangus, and Nelore, as well as two local breeds at risk of extinction. The main objective is to identify and rank phenotypic variables, including blood, clinical, hair, and health variables, demonstrating causal linkage with the live weight of the cows analyzed. Initially, high correlations were identified between different variables included in this study; then, using advanced Machine learning (ML) techniques and the application of Shapley additive explanations (SHAP), a deeper understanding was provided of the factors strongly associated with adaptability in these environments, and, therefore, the respective zootechnical performance. The association between cattle genotypic components linked with the season of the year proved to be the most influential factor on cattle live weight. Variables such as hair length, hematocrit, phosphatase, phosphorus, creatine phosphokinase, creatinine, protein, cortisol, calcium, and the presence of endoparasites were highlighted, demonstrating their hierarchical importance for animal selection. ML models are effective tools for establishing hierarchies of relevance in complex phenotypic multivariable, which is crucial in breeding programs for different zootechnical species and in special and specific environments like wetlands.

ABSTRACT Desertification is the degradation process caused by climatic conditions and human activities that results in loss of soil productivity and decline in vegetation growth in the long term. Several indices related to vegetation, soil and climate are used to monitor desertification, but few studies explore qualitative and quantitative aspects of indices on desertification on spatial and hierarchical scale. This study aims to identify and measure indices related to increased risk of desertification on global, local and hierarchical scales using multinomial logistic regression models. Images from TM, ETM+ and OLI sensor from 1997 to 2018 in the end of dry and rainy seasons were used to quantify NDVI, TGSI, albedo, temperature, aridity index, evapotranspiration and precipitation on global spatial scale (Irauçuba Centro Norte) and local spatial scale (Miraíma, Canindé, Irauçuba and Santa Quitéria). GISD was calculated by geometric mean of weighted indices and segmented into 8 classes of susceptibility to desertification (hierarchical scale). The results showed that the best models were obtained on local scale and for the end of the rainy season. Temperature proved to be the most important variable for increased risk of desertification on global, local and hierarchical scales. Therefore, the increase in the risk of desertification in the studied areas is due to human activities of deforestation, overgrazing and fire. These factors contributed to reduction of vegetation cover and increase in temperature, changing the microclimatic, which led to decline in precipitation and worsening of desertification. term TM ETM 199 201 NDVI TGSI albedo temperature index Norte Miraíma, Miraíma (Miraíma Canindé Quitéria.

Abstract Background: Non-invasive ventilation is a therapeutic strategy for patients with acute respiratory failure. Objective: To analyze the relationship between the sociodemographic and clinical variables of patients hospitalized in internal medicine services and the adaptation to and complications of non-invasive ventilation. Methodology: A retrospective observational cohort study was carried out with a sample of 239 patients. Data were collected from electronic records in the information system SClínico, using a data extraction guide. Results: A total of 25.1% of the participants did not adapt to non-invasive ventilation, and this was significantly associated with oral feeding, confusion, and the use of mechanical restraint measures. Complications occurred in 33.5% of the sample. The most frequent complications were secretions, nasal injuries, and vomiting. There was a statistically significant association between the number of complications and patients fed by nasogastric tube, confused, with mechanical restraint measures, and wearing an oronasal mask. Conclusion: The monitoring of patients on non-invasive ventilation should be carried out by a specialized nursing team. Protocols should be implemented to prevent complications and promote patient adaptation to non-invasive ventilation.

ABSTRACT Introduction/framework/objectives Salt production, especially using artisanal methods, does not exist in all countries, given the climatic and logistical requirements. Portugal has some tradition in this sector, but even so, most professionals working in Occupational Health and Safety have no experience in the area. The aim of this review was to summarize the most relevant and recent publications, to improve their performance capacity and enhance the productivity, satisfaction and well-being of the workers involved. Methodology This is a Bibliographic Review, initiated through a search carried out in April 2023 in the databases “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina and RCAAP”. Content Salt pans can be inland (far from the sea, using groundwater with a high salt content) or coastal. The former are scarcer in Portugal and only exist between Lisbon and Coimbra. Over time, in our country, evaporation was carried out by fire and sun. The latter is believed to have been developed by the Romans who created the first version of salt flats. At national level there is evidence of salt production since the end of the Neolithic, but here more frequently with the use of fire. Throughout Europe there has been a decline in artisanal versus industrial salt production, even in sea salt pans (especially on the northwest coast of France and, in Portugal, on the western coasts). Artisanal production in our country is more prevalent in the Figueira da Foz area. The product obtained via artisanal production has better quality, particularly in terms of flavor and nutritionally (via industrial production the taste is more metallic). Portugal is a large producer and consumer of traditional salt. The climatic characteristics suit production, due to summers with frequent high temperatures and strong, hot winds. National salt was and is consumed in other European countries; for presenting superior quality, even though it is more expensive. Production depends on the climate, namely insolation (number of hours in the sun), precipitation, temperature, cloudiness and winds (which affect evaporation). In other words, this is more intense and faster if the air temperature is higher, such as with more dry winds (which are generally more frequent in summer); low precipitation is also favorable. Salt production has been increasing, due to growing industrial needs. To be used in this last situation, it must be at 100% purity. Discussion and Conclusions No bibliography was found that referred the dimension of occupational health and safety in this professional sector. Based on the authors' theoretical and practical experience, the most relevant risk factors and risks in the sector are described: ultraviolet radiation and possible skin cancer, cataracts and other associated injuries; thermal discomfort and eventual higher accident rates associated with motor incoordination, worse cardiovascular adjustment, as well as disorientation and ability to make decisions; forced/maintained loads and/or postures and possible musculoskeletal injuries, emergence/worsening of hernia pathology and falling objects at the same level and possible bruises, skin lacerations and/or fractures. It would be interesting to learn more about the national panorama of this sector, through studies that hierarchically stratify the risk, also accurately describing occupational illnesses and associated accidents, as well as more effective measures to mitigate these issues.

RESUMO Introdução/enquadramento/objetivos A produção de sal, sobretudo com métodos artesanais, não existe em todos os países, dadas as exigências climáticas e logísticas. Portugal apresenta alguma tradição nesse setor mas, ainda assim, a maioria dos profissionais a exercer na Saúde e Segurança Ocupacionais não tem experiência na área. Pretendeu-se com esta revisão resumir o que mais relevante e recente se publicou, de forma a melhorar a capacidade de atuação destes e a potenciar a produtividade, satisfação e bem-estar dos trabalhadores afetos. Metodologia Trata-se de uma Revisão Bibliográfica, iniciada através de uma pesquisa realizada em abril de 2023 nas bases de dados “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina e RCAAP”. Conteúdo As salinas podem ser interiores (afastadas do mar, usando água subterrânea com elevado conteúdo em sal) ou litorais. As primeiras são mais escassas em Portugal e apenas existem entre Lisboa e Coimbra. Ao longo do tempo, no nosso país, a evaporação era realizada pelo fogo e sol. Esta última acredita-se que foi desenvolvida pelos romanos que, de certa forma, criaram a primeira versão das salinas. A nível nacional há evidência de produção de sal desde o final do Neolítico, mas aqui mais frequente com a utilização do fogo. Por toda a Europa tem existido um declínio da produção artesanal de sal, versus industrial, mesmo em salinas marítimas (sobretudo na costa noroeste de França e, em Portugal, na costa ocidental). A produção artesanal no nosso país é mais prevalente na zona da Figueira da Foz. O produto obtido via artesanal tem mais qualidade, nomeadamente a nível de sabor e nutricionalmente (via industrial o paladar é um pouco mais metálico). Portugal é um grande produtor e consumidor de sal tradicional. As caraterísticas climáticas adequam-se à produção, devido aos verões com temperaturas elevadas frequentes e ventos fortes e quentes. O sal nacional era e é consumido noutros países europeus, por apresentar qualidade superior, mesmo tendo um preço mais elevado. A produção depende do clima, nomeadamente a insolação (número de horas ao sol), precipitação, temperatura, nebulosidade e ventos (que condicionam a evaporação). Ou seja, esta é mais intensa e rápida se a temperatura do ar for mais elevada, tal como com mais ventos secos (que geralmente são mais frequentes no Verão); a baixa precipitação também é favorável. A produção de sal tem vindo a aumentar, até pelas crescentes necessidades industriais. Para ser usado nesta última situação, deverá estar no patamar de 100% de pureza. Discussão e Conclusões Não se encontrou bibliografia que fizesse referência à dimensão da saúde e segurança ocupacionais neste setor profissional. Em função de experiência teórica e prática dos autores, descrevem-se os fatores de riscos e riscos mais relevantes do setor: radiação ultravioleta e eventual cancro de pele, cataratas e outras lesões associadas; desconforto térmico e eventual maior sinistralidade associada a descoordenação motora, pior ajuste cardiovascular, bem como desorientação e capacidade de tomar decisões; cargas e/ou posturas forçadas/mantidas e eventuais lesões músculo-esqueléticas, surgimento/agravamento de patologia herniária e queda de objetos e ao mesmo nível e eventuais equimoses, lacerações cutâneas e/ou fraturas. Seria interessante conhecer melhor o panorama nacional deste setor, através de estudos que estratificassem hierarquicamente o risco, descrevendo ainda com rigor as doenças profissionais e acidentes associados, bem como medidas mais eficazes para atenuar essas questões.

ABSTRACT Introduction/framework/objectives: There have always been employers, managers and/or co-workers with less correct and disruptive behaviors, with possible consequences in terms of physical and emotional health, in addition to direct intervention in work parameters (such as performance, satisfaction, productivity and profit). Within this dimension there is a very wide variation between more subtle and possibly less serious situations, to the opposite. The aim of this review is to address the softer part of this spectrum and, possibly, more discreet and frequent, in order to provide Occupational Health and Safety Professionals with more weapons, to better guide the situation. Methodology: This is a Bibliographic Review, initiated through a search carried out in April 2023 in the databases “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina and RCAAP”. Content: Civility can be defined as tolerance, respect and concern for others; with the possibility of sharing and disagreeing in a polite and cooperative way, based on treating with dignity; which can mitigate the effects of workload on employees’ mental health. Incivility occurs when an individual violates respect for others by being rude and/or condescending, leading to disrespect, conflict and anxiety. In other words, it is a deviant behavior that is not very intense, violating the rules of good work conduct. This review also mentions data relating to possible classifications of Incivility, elements that can commit it, factors that increase or mitigate the risk of being a target of this phenomenon, professional areas most affected, some international statistics; as well as personal and work consequences and ways to mitigate the problem. Discussion and Conclusions: Addressing and drawing attention to Workplace Incivility will certainly make everyone involved more aware and capable of mitigating or eliminating it, contributing to the construction of healthier cultures and work environments (physically and emotionally); creating more competitive and profitable institutions. It would be interesting to see if, at a national level, there are employers who have already studied the topic inside (or intend to do so in the future), summarizing the respective incidences/prevalence of the different subtypes of uncivilized behavior, socio-demographic-professional characteristics of the aggressors and attacked workers, measures taken and their effectiveness, publishing this in a specialized magazine.

RESUMO Introdução/enquadramento/objetivos: Desde sempre que existiram empregadores, chefias e/ou colegas de trabalho com comportamentos menos corretos e perturbadores, com eventuais consequências a nível da saúde física e emocional, para além da interação com parâmetros laborais (como desempenho, satisfação, produtividade e lucro). Dentro desta dimensão existe uma variação muito ampla entre situações mais subtis e eventualmente menos graves, até o oposto. Pretende-se com esta revisão abordar a parte mais suave deste espetro e, eventualmente, mais discreta e frequente, de forma a dotar os Profissionais da Saúde e Segurança Ocupacionais de mais armas, para melhor orientarem a situação. Metodologia: Trata-se de uma Revisão Bibliográfica, iniciada através de uma pesquisa realizada em abril de 2023 nas bases de dados “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina e RCAAP”. Conteúdo: Civilidade pode ser definida como tolerância, respeito e preocupação pelos outros; com possibilidade de partilhar e discordar de uma forma educada, cooperando, baseada no trato com dignidade; podendo atenuar os efeitos da carga de trabalho na saúde mental dos funcionários. Incivilidade ocorre quando um indivíduo viola o respeito por terceiros, sendo rude e/ou condescendente, levando a um ambiente de conflito e ansiedade. Ou seja, é um comportamento desviante não muito intenso, mas violando as normas/condutas de trabalho. Nesta revisão são ainda mencionados dados relativos a eventuais classificações de Incivilidade, elementos que a podem cometer, fatores que potenciam ou atenuam o risco de ser alvo deste fenómeno, áreas profissionais mais atingidas e algumas estatísticas internacionais, consequências pessoais e laborais e forma de atenuar o problema. Discussão e Conclusões: Abordar e chamar a atenção para a Incivilidade Laboral certamente conseguirá que todos os envolvidos ficam mais atentos e capazes de a atenuar ou eliminar, contribuindo para a construção de culturas e ambientes de trabalho mais saudáveis (física e emocionalmente); criando instituições mais competitivas e lucrativas. Seria curioso perceber se a nível nacional existem empregadores que já tenham estudado o tema dentro de suas portas (ou pretendam fazê-lo futuramente), resumindo as respetivas incidências/prevalências dos diversos subtipos de comportamentos incivilizados, caraterísticas socio-demográfico-profissionais dos agressores e agredidos, medidas tomadas e eficácia das mesmas, divulgando tal em revista especializada.

ABSTRACT Paracoccidioidomycosis (PCM) is a systemic disease endemic to Latin American countries, with a high impact in terms of morbidity, mortality and costs for the health system if patients progress to advanced stages. This work aimed to collect data published in publications on autochthonous cases of PCM, from the first cases diagnosed in Paraguay, with a description of the historical context and identifying the pioneers in the diagnosis in Paraguay, following a chronological order, to the most recently reported cases. Methodology: search in national libraries and online databases of PCM cases in Paraguay, published in national historical scientific journals and other sources available in print format, and more recent scientific articles available in electronic format, respectively. Results: 479 cases of PCM were identified in publications between the years 1935 and 2023, corresponding to autochthonous cases and whose diagnoses were made in Paraguayan territory. Dr. Juan Boggino and collaborators were responsible for the first diagnoses in the country. The predominant clinical form was chronic. The average age was 45.78 years. The vast majority of patients diagnosed were from the Eastern Region of the country, predominantly male farmers. Conclusion: PCM is an endemic disease in Paraguay. Since the first cases were diagnosed and until today, patients with a severe and disabling course of the disease have been detected, which demonstrates the need to disseminate its knowledge and expand the early diagnostic capacity at the national level. Due to its clinical pleomorphism and its ability to simulate other diseases, it is important to include PCM as a differential diagnosis for patients who present risk factors for the development of the disease.

RESUMEN La Paracoccidioidomicosis (PCM), es una enfermedad sistémica endémica de países de América Latina, con alto impacto en términos de morbilidad, mortalidad y costos para el sistema de salud si los enfermos progresan a sus estadios avanzados. Este trabajo tuvo como objetivo recopilar datos divulgados en publicaciones sobre casos autóctonos de PCM, desde los primeros casos diagnosticados en Paraguay, con una descripción del contexto histórico e identificando a los pioneros en el diagnóstico en Paraguay, siguiendo un orden cronológico, hasta los casos más recientemente informados. Metodología: búsqueda en bibliotecas nacionales y bases de datos online de casos de PCM en Paraguay, publicados en revistas científicas históricas nacionales y otras fuentes disponibles en formato impreso, y artículos científicos más recientes disponibles en formato electrónico, respectivamente. Resultados: Se identificaron 479 casos de PCM en publicaciones entre los años 1935 y 2023, correspondientes a casos autóctonos y cuyos diagnósticos fueron realizados en territorio paraguayo. El Dr. Juan Boggino y colaboradores fueron los responsables de los primeros diagnósticos en el país. La forma clínica predominante fue la crónica. La media de edad de 45,78 años. La gran mayoría de los pacientes diagnosticados fueron oriundos de la Región Oriental del país, predominantemente hombres agricultores. Conclusión: La PCM es una enfermedad endémica del Paraguay, desde los primeros casos diagnosticados y hasta hoy en día, son detectados pacientes con una evolución grave y discapacitante de la enfermedad, lo que demuestra la necesidad de la difusión de su conocimiento y ampliación de la capacidad diagnóstica precoz a nivel nacional. Debido a su pleomorfismo clínico y su capacidad de simular otras enfermedades, es importante incluir a la PCM como diagnóstico diferencial de pacientes que presenten factores de riesgo para el desarrollo de la enfermedad.

ABSTRACT Introduction: the COVID-19 pandemic presented challenges worldwide. The acceptance of vaccines in the population is essential as a preventive measure. It is undeniable that there are factors that increase rejection or questioning in this regard, which may be related to culture, politics, trust, convenience, experience in health services, and also the opinion of the environment. Objective: to determine the percentage of students and teachers vaccinated, and the number of doses applied against COVID-19 in Facultad de Odontología at the Universidad Nacional de Asunción, in the year 2022. Methodology: cross-sectional descriptive observational study, applying a digital survey with 23 questions about knowledge, application and self-perception of the vaccine; in addition to demographic data. Results: 168 respondents were included, 128 students and 40 teachers. 80.0 % were women. 97.6 % have been vaccinated against COVID-19, the majority (85.4 %) received three doses of the vaccine. 34.1 % received the Covaxin vaccine, 32.9 % Sputnik V, 15.9 % AstraZeneca and 17.1 % others (Pfizer, Sinopharm and Moderna). 35.1 % had doubts about the effectiveness but most of them were applied anyway. 94.1 % considered the vaccine necessary and 88.7 % safe. 78.5 % responded that coverage is high to prevent the symptoms of the disease. 35.1% mentioned feeling fully protected with the vaccine. 78.6% know that some adverse reaction may occur after application. Conclusion: almost all of the respondents were vaccinated and had received all three doses of the COVID-19 vaccine at the time of the survey.

RESUMEN Introducción: la pandemia por COVID-19 presentó desafíos a nivel mundial. La aceptación de las vacunas en la población es indispensable como medida preventiva. Es innegable que existen factores que elevan el rechazo o cuestionamiento al respecto, que pueden estar relacionados con la cultura, política, confianza, conveniencia, experiencia en servicios sanitarios, también la opinión del entorno. Objetivo: determinar el porcentaje de estudiantes y docentes vacunados, y el número de dosis aplicadas contra el COVID-19 de la Facultad de Odontología de la Universidad Nacional de Asunción, en el año 2022. Metodología: estudio observacional descriptivo de corte transversal, aplicando una encuesta en digital con 23 preguntas acerca del conocimiento, aplicación y autopercepción de la vacuna; además de datos demográficos. Resultados: fueron incluidos 168 encuestados, 128 estudiantes y 40 docentes. 80,0 % fueron mujeres. 97,6 % se ha vacunado contra COVID-19, la mayoría (85,4 %) se aplicó tres dosis de la vacuna. 34,1 % se aplicó la vacuna Covaxin, 32,9 % Sputnik V, 15,9 % AstraZeneca y 17,1 % otras (Pfizer, Sinopharm y Moderna). El 35,1 % tuvo dudas acerca de la eficacia pero que en su mayoría se aplicaron igualmente. El 94,1 % consideró necesaria y el 88,7 % segura la vacuna. El 78,5 % respondió que la cobertura es elevada para prevenir los síntomas de la enfermedad. El 35,1 % mencionó sentirse protegido en su totalidad con la vacuna. El 78,6 % sabe que puede presentarse luego de la aplicación alguna reacción adversa. Conclusión: casi la totalidad de los encuestados se encontraban vacunados y se aplicaron las tres dosis de la vacuna COVID-19 al momento de la encuesta.

Abstract Frailty, defined as an inappropriate response to stressful situations due to the loss of physiological reserve, was initially described in the elderly population, but is currently being identified in younger populations with chronic diseases, such as chronic kidney disease. It is estimated that about 20% of patients are frail at the time of kidney transplantation (KT), and there is great interest in its potential predictive value for unfavorable outcomes. A significant body of evidence has been generated; however, several areas still remain to be further explored. The pathogenesis is poorly understood and limited to the extrapolation of findings from other populations. Most studies are observational, involving patients on the waiting list or post-KT, and there is a scarcity of data on long-term evolution and possible interventions. We reviewed studies, including those with Brazilian populations, assessing frailty in the pre- and post-KT phases, exploring pathophysiology, associated factors, diagnostic challenges, and associated outcomes, in an attempt to provide a basis for future interventions.

Resumo A fragilidade, conceituada como a resposta inadequada a situações de estresse devido à perda da reserva fisiológica, foi descrita incialmente na população idosa, mas atualmente vem sendo identificada em populações mais jovens com doenças crônicas, como a doença renal crônica. Estima-se que cerca de 20% dos pacientes sejam frágeis no momento do transplante renal (TR), e há grande interesse pelo seu potencial valor preditor de desfechos desfavoráveis. Um número expressivo de evidências tem sido gerado, entretanto, ainda persistem várias áreas a serem mais exploradas. A patogênese é pouco conhecida e limitada à extrapolação dos achados de outras populações. A maioria dos estudos é observacional, envolvendo pacientes em lista ou após o TR, e há escassez de dados sobre a evolução em longo prazo e possíveis intervenções. Revisamos os estudos, incluindo aqueles com populações brasileiras, de avaliação de fragilidade nas fases pré e pós-TR, explorando a fisiopatologia, os fatores associados, os desafios do diagnóstico e os desfechos associados, na tentativa de fornecer embasamento para futuras intervenções. fisiológica idosa crônicas crônica Estimase Estima se 20 TR , (TR) desfavoráveis gerado entretanto exploradas observacional intervenções brasileiras pósTR, pósTR pós pós-TR fisiopatologia associados 2 (TR

Abstract Introduction. Livestock farming with Creole cattle is practiced in rural areas with challenging characteristics for species management. Objective. To describe the production system and the socio-cultural and technical-economic factors affecting the production of Nunkiní Creole cattle (Bos taurus). Materials and methods. The study was conducted from November 2020 to October 2021 in nine livestock production units of Nunkiní, Calkiní municipality, Campeche, Mexico. Information was obtained from an interview form with social, cultural, technical, and economic study variables, applied to selected producers. Data were analyzed using descriptive statistics and ANOVA. Results. Livestock farming was carried out by men (100 %), with an average age of 58.44 years. The average years of experience were 34.61. Younger producers had higher levels of education and less experience, and were responsible for the production units of higher technological levels. The size of the livestock production unit ranged from five to twenty-two cattle (average of 14). Feeding management followed a transhumance scheme, with cattle being free-ranging on ejido lands and from May to December and semi-stabled from January to April, grazing on cultivated pastures and supplemented with agricultural residues. With the zootechnical management implemented by the producers, an average pregnancy rate of 83 % was achieved. The main product marketed was fresh meat in cuts and direct sale to consumers, with an average price of 2.675 USD$/kg. Conclusion. It is traditional extensive system that takes advantage of the common use of grasslands. It involves experienced but older producers, with small investments, and serves to strengthen their family economy. This activity is threatened by the lack of revaluation of Creole cattle and the introduction of exotic breeds in the area to maximize production.

Resumen Introducción. La ganadería con bovinos criollos se práctica en espacios rurales con características difíciles para el manejo de las especies. Objetivo. Describir el sistema productivo y los factores socioculturales y técnico-económicos que afectan la producción del bovino criollo de Nunkiní (Bos taurus). Materiales y métodos. El estudio se realizó entre noviembre del 2020 a octubre del 2021, en nueve unidades de producción pecuarias de Nunkiní en el municipio de Calkiní, Campeche, México. La información se obtuvo de una cédula de entrevista con variables de estudio sociales, culturales, técnicas y económicas, aplicada a productores seleccionados. Los datos se analizaron mediante estadística descriptiva y ANDEVA. Resultados. La crianza del ganado la realizaron hombres (100 %), con edad promedio de 58,44 años. Los años de experiencia promedio fueron de 34, 61. Los productores jóvenes tuvieron mayor escolaridad y menor experiencia, y se encargaron de las unidades de producción de mayor nivel tecnológico. El tamaño de la unidad de producción pecuaria varió de cinco a veintidós bovinos (media de 14). El manejo alimenticio tuvo un esquema de trashumancia, donde de mayo a diciembre estuvieron libres en tierras ejidales y de enero a abril se manejaron semiestabulados, con pastoreo en potreros cultivados y suplementados con residuos agrícolas. Con el manejo zootécnico implementado por los productores, se obtuvo un promedio de 83 % de preñez. El producto principal comercializado fue carne fresca en cortes y venta directa al consumidor, con un precio promedio de 2,675 USD$/kg. Conclusión. Es un sistema tradicional extensivo que aprovecha el uso común de los agostaderos. Con productores de experiencia, pero de edad avanzada, de pequeña inversión y le sirve para fortalecer su economía familiar. Dicha actividad se ve amenazada por la falta de revalorización del bovino criollo y la introducción de razas exóticas en la zona para maximizar la producción.

Abstract Introduction: Chronic kidney disease (CKD) and metabolic syndrome (MS) are recognized as public health problems which are related to overweight and cardiometabolic factors. The aim of this study was to develop a model to predict MS in people with CKD. Methods: This was a prospective cross-sectional study of patients from a reference center in São Luís, MA, Brazil. The sample included adult volunteers classified according to the presence of mild or severe CKD. For MS tracking, the k-nearest neighbors (KNN) classifier algorithm was used with the following inputs: gender, smoking, neck circumference, and waist-to-hip ratio. Results were considered significant at p < 0.05. Results: A total of 196 adult patients were evaluated with a mean age of 44.73 years, 71.9% female, 69.4% overweight, and 12.24% with CKD. Of the latter, 45.8% had MS, the majority had up to 3 altered metabolic components, and the group with CKD showed statistical significance in: waist circumference, systolic blood pressure, diastolic blood pressure, and fasting blood glucose. The KNN algorithm proved to be a good predictor for MS screening with 79% accuracy and sensitivity and 80% specificity (area under the ROC curve – AUC = 0.79). Conclusion: The KNN algorithm can be used as a low-cost screening method to evaluate the presence of MS in people with CKD.

Resumo Introdução: A doença renal crônica (DRC) e a síndrome metabólica (SM) são reconhecidas como problemas de saúde pública relacionados ao excesso de peso e a fatores cardiometabólicos. O objetivo deste estudo foi desenvolver um modelo para prever a SM em pessoas com DRC. Métodos: Este foi um estudo transversal prospectivo de pacientes de um centro de referência em São Luís, MA, Brasil. A amostra incluiu voluntários adultos classificados de acordo com a presença de DRC leve ou grave. Para o rastreamento da SM, o algoritmo de classificação k-nearest neighbors (KNN) foi utilizado com os seguintes dados: sexo, tabagismo, circunferência do pescoço e relação cintura-quadril. Os resultados foram considerados significativos com p < 0,05. Resultados: Foram avaliados 196 pacientes adultos com média de idade de 44,73 anos, 71,9% do sexo feminino, 69,4% com sobrepeso e 12,24% com DRC. Desses últimos, 45,8% apresentaram SM, a maioria tinha até 3 componentes metabólicos alterados, e o grupo com DRC apresentou significância estatística em: circunferência da cintura, pressão arterial sistólica, pressão arterial diastólica e glicemia de jejum. O algoritmo KNN comprovou ser um bom preditor para a triagem de SM com acurácia e sensibilidade de 79% e especificidade de 80% (área sob a curva ROC – AUC = 0,79). Conclusão: O algoritmo KNN pode ser usado como um método de triagem de baixo custo para avaliar a presença de SM em pessoas com DRC.
