Abstract Introduction: Deep brain stimulation (DBS) is effective in treating Parkinson's Disease (PD) through the use of an implantable pulse generator (IPG), which can be rechargeable (r-IPG) or non-rechargeable (nr-IPG). This study examines evidence on these devices regarding their duration, quality of life, adverse events, and costs in patients with PD. Materials and methods: Rapid Systematic Review following Cochrane Group guidelines. Results: Of 10 studies, 2 included only PD patients, and the others included various neurological disorders. Patients using an r-IPG from the start of treatment or as a replacement reported high satisfaction, with no significant differences compared to nr-GPI. In PD patients, the average replacement time for nr-GPI was 5.1 years, while r-GPI had a lifespan of 9 to 15 years. Although r-GPI reduces surgical interventions, it presents specific risks, such as recharging failures and missed charging sessions, while nr-GPI requires frequent replacements and is associated with a higher infection risk. The use of r-GPI showed significant long-term cost savings. Discussion: Studies indicate that r-GPI offers benefits in satisfaction, lower complication risk, and greater long-term cost-effectiveness due to the reduced need for replacements. The specific risks of each device suggest the importance of personalized selection based on the patient's needs and preferences. Conclusions: nr-GPI devices have a shorter duration, while r-GPI devices have demonstrated greater long-term cost-effectiveness and higher patient satisfaction rates.

Resumen Introducción: La estimulación cerebral profunda (ECP) es efectiva en el tratamiento de la enfermedad de Parkinson (EP), mediante el uso de un generador de pulso implantable (GPI) que puede ser recargable (GPI-r) o no recargable (GPI-nr). Este estudio examina la evidencia de estos dispositivos en relación con la duración, la calidad de vida, los eventos adversos y los costos en pacientes con EP. Materiales y métodos: Revisión sistemática rápida según pautas del grupo Cochrane. Resultados: De 10 estudios, 2 incluyeron pacientes con EP y los demás diferentes trastornos neurológicos. Los pacientes con generadores de pulso implantable con batería recargable (GPI-r) desde el inicio del tratamiento o como reemplazo reportaron alta satisfacción, sin diferencias significativas frente a los no recargables (GPI-nr). En pacientes con EP, el tiempo de sustitución de un GPI-nr fue de 5,1 años, mientras que los GPI-r mostraron una vida útil de 9 a 15 años. Aunque el GPI-r reduce las intervenciones quirúrgicas, presenta riesgos específicos, como fallas de recarga y olvido, mientras que el GPI-nr requiere reemplazos frecuentes y conlleva un mayor riesgo de infecciones. El uso de GPI-r mostró un ahorro significativo en costos a largo plazo. Discusión: Los estudios indican que el GPI-r ofrece beneficios en satisfacción, un menor riesgo de complicaciones y una mayor rentabilidad a largo plazo, debido a la reducción en la necesidad de reemplazos. Los riesgos específicos de cada dispositivo sugieren la importancia de una selección personalizada según las necesidades y preferencias del paciente. Conclusiones: Los GPI-nr presentan una menor duración, mientras que los GPI-r han demostrado una mayor rentabilidad a largo plazo y mejores tasas de satisfacción entre los pacientes.

ABSTRACT The genus Piptadenia Benth. has undergone several changes in its circumscriptions throughout its history, given the difficulty of its phylogenetic placement. Considering that palynological contributions have been significant for differentiating taxa within the Mimoseae tribe , the present study aims to characterize the representatives of the genus as well as describe the pollen grains of some taxa still unpublished in the literature. Three types of pollen grains were identified based on the number of grains per polyad considering the number of pollen grains and their ornamentation. However, other palynological characters are similar among species, supporting the monophyly of the genus. All species showed similarities, especially regarding size and shape, varying mainly in the number of pollen grains composing the polyads (8, 12, and 16). This variation has already been confirmed by morphological and molecular data. This study presents unprecedented palynological characterization of the species: Piptadenia affinis, P. cuzcoënsis, P. gonoacantha, P. imatacae, P. killipii, P. micracantha, and P. robusta.

ABSTRACT Water application to cultivated soil is often done without careful consideration in irrigated agriculture, leading to inefficient or suboptimal water usage. In many instances, the intricate relationship between soil, water, and plants, as well as the potential and limitations of irrigation systems, is overlooked. Sustainable irrigated agriculture necessitates the development of a soil moisture monitoring system that curtails water loss and enhances overall efficiency. This study aimed to develop and assess the efficiency of an intelligent system for monitoring soil moisture. The system comprises two stations: the first collects data on apparent soil moisture parameters using sensors, while the second transmits this data to a central processing station. The system precisely determines current soil moisture values, enabling estimation of the required irrigation water volume to meet the crop’s water demand based on field capacity. Results from the calibration curve of the sensors indicate that the system can measure current soil moisture precisely, aiding in irrigation management. For irrigated areas under unsaturated soil conditions, it is recommended to use tensiometers due to their higher reliability between field capacity and permanent wilting point, ensuring more accurate irrigation practices.

RESUMO Na agricultura irrigada, é comum a aplicação de água no solo cultivado sem critério, resultando em uso ineficiente ou não otimizado da água. Em muitos casos, a relação solo-água-planta, bem como as potencialidades e limitações dos sistemas de irrigação são ignoradas. A agricultura irrigada sustentável requer o desenvolvimento de um sistema de monitoramento da umidade do solo que evite a perda de água e melhore a eficiência do uso. O objetivo deste estudo foi desenvolver e avaliar a eficiência de um sistema inteligente de monitoramento da umidade do solo. O sistema é composto por duas estações: a primeira coleta os dados sobre parâmetros de umidade aparente do solo usando sensores, enquanto a segunda transmite esses dados para uma estação de processamento central. O sistema determina precisamente os valores atuais de umidade do solo, permitindo estimar o volume de água de irrigação necessário para atender à demanda hídrica da cultura com base na capacidade de campo. Os resultados da curva de calibração dos sensores indicam que o sistema pode medir com precisão a umidade do solo atual, auxiliando no manejo da irrigação. Para áreas irrigadas em condições de solo não saturado, recomenda-se o uso de tensiômetros devido à sua maior confiabilidade entre a capacidade de campo e o ponto de murcha permanente, garantindo práticas de irrigação mais precisas.

Abstract: En | Text: En | PDF: En

ABSTRACT The São Francisco Submedium Valley in Brazil is the country’s most important table grape exportation region. In 2015, a new pest was reported in the area, the American grapevine moth Lasiothyris luminosa (Razowski & Becker) (Tortricidae), causing significant damage from the bud flowers until the grape berries in the harvesting period. The present work aimed to evaluate artificial diets to guarantee the rearing of L. luminosa in laboratory conditions. Two artificial diets used to rear Anticarsia gemmatalis Hübner and Helicoverpa zea (Boddie) were compared to the species’ natural host (grape berries). It was evaluated the larva, pupal, and larval-pupal period, longevity, fecundity, larval and pupal viability, and sex ratio. L. luminosa completed its cycle in both artificial diets, making it possible to use both to maintain the species in the laboratory. The larval and larval-adult period were shorter for the treatment with A. gemmatalis artificial diet. Also, this diet provided greater pupal viability and higher fecundity. Thus, the A. gemmatalis diet is more indicated to rear L. luminosa in the laboratory than the H. zea diet and grape berries.

ABSTRACT In response to the increasing uncertainties in agricultural decision-making, driven by market fluctuations and changes in environmental conditions, this research implemented the Balanced DecisionMaking Method (BDMM) to improve crop selection on a farm in western Bahia. The BDMM integrates multiple decision-making methods-TOPSIS, PROMETHEE II, and the Borda method-to provide a comprehensive and balanced evaluation. Both qualitative and quantitative data were gathered from literature, insights from two decision-makers, and the authors of the article. Qualitative factors, such as cost estimates, market prices, and labor requirements, were sourced from various references, while quantitative data focused on customer demand and expert consensus regarding pest risk. The combination of these data sources and the application of the proposed method enabled a detailed analysis that reflected the combined preferences and needs of each producer. The BDMM facilitated consensus among the producers, supporting decisions that optimize both economic performance and environmental sustainability.

RESUMO Apresentamos uma visão geral do evento hidrológico sem precedentes que ocorreu no estado do Rio Grande do Sul no final de abril e início de maio de 2024, causando inundações e movimentos de massa em uma escala nunca vista no Brasil. A precipitação que causou o desastre é incomparável a qualquer evento recente no país em termos de escala espacial e temporal. A intensa e prolongada precipitação resultou em enchentes recordes, desde pequenos rios com áreas de drenagem abaixo de 1.000 km2 até a Laguna dos Patos, que drena mais de 180.000 km2. As chuvas também levaram a movimentos de massa que ocupam o primeiro lugar no Brasil em termos de extensão espacial e número de ocorrências. Enchentes rápidas com níveis extremos de água ocorreram em regiões montanhosas, enquanto nas áreas mais baixas as cheias tiveram longa duração, com os níveis de água permanecendo elevados por cerca de 30 dias. Este desastre provavelmente ocupa a primeira posição no Brasil em número de pessoas deslocadas e danos a propriedades e infraestruturas. Quase 200 fatalidades ocorreram devido ao desastre e falhas em estruturas de proteção. O evento hidrológico de abril e maio oferece um vislumbre do que pode ser esperado nas próximas décadas devido às mudanças climáticas em uma região que abrange o Sul do Brasil e partes dos países vizinhos.

ABSTRACT We present an overview of the unprecedent hydrological event that occurred in Rio Grande do Sul state in late April and early May 2024, causing floods and landslides in a scale that was not seen before in Brazil. The rainfall that caused the disaster is incomparable to any recent event in Brazil at large spatial and temporal scale. The intense and long-lasting precipitation led to record floods from small rivers with drainage areas below 1000 km2 to the Patos Lagoon, which drains more than 180,000 km2. The rainfall also led to landslides that rank first in Brazil in terms of spatial scale and number of occurrences. Mountain rivers experienced flash floods with extreme water levels, while in the lowlands the large rivers and the Patos Lagoon experienced long duration flooding, with stage remaining high for about 30 days. The flood event is probably ranked first in terms of displaced people and damage to property and infrastructure in Brazil. Almost 200 fatalities occurred due to the disaster and protection structure failures. The April-May hydrological event show a glimpse of what can be expected along the coming decades due to climate change in a region that covers South Brazil, and parts of the neighboring countries.

RESUMO: Neste artigo, documentamos as ecologias afetivas que se formam entre discentes de licenciatura em educação do campo e as sementes crioulas. Para análise dos dados, seguimos a inspiração etnográfica nomeada Teoria Ator-Rede. Argumentamos que as histórias involucionárias narradas pelas estudantes sobre a relacionalidade com a terra são possibilidades de adiar o fim do mundo. O que surge entre o solo, o ar, as casas, as famílias, as águas, os nutrientes, molda a vida campesina, paisagens e ritmos não tão facilmente delimitados. Manter a mão no chão, conservar artefatos e pensar sobre a manutenção das práticas, que são educativas, são exercícios de resistência e estratégias de manutenção da vida, que envolvem presente, passado e futuro. Com este estudo, pretende-se trazer considerações sobre o modo como produzimos conhecimento para contribuir com as pesquisas sobre o Ensino de Ciências a partir do diálogo entre ontologias e coletivos heterogêneos que nos permitam tecer um mundo onde caibam muitos

ABSTRACT: This study documents the affective ecologies that form between undergraduate students in rural education and other-than-humans and creole seeds. To analyze the data collected, we followed the ethnographic inspiration adopted by the Actor-Network Theory. We argue that the involutionary stories narrated by the students about the relationality with the earth are possibilities to postpone the end of the world. What emerges between the soil, the air, the houses, the families, the waters, the Nutrients shape peasant life, landscapes and rhythms that are not so easily delimited. Keeping the hands on the ground, repairing artifacts and thinking about the maintenance of practices, are resistance exercises and life maintenance strategies that involve the present, past and future. With this study, we intend to bring some considerations about the way we produce knowledge to contribute to research on Science Teaching based on dialogues between ontologies and heterogeneous collectives that allow us to weave a world where many can fit

ABSTRACT Evidence suggests a risk of maternal transmission of chikungunya virus (CHIKV) during the first and third trimesters, potentially leading to miscarriage or neurological consequences for the fetus. This study aimed to conduct a serological survey for CHIKV among women with high-risk pregnancies and analyze neonatal variables and placental tissue alterations. From March 2016 to April 2021, serological, histological, and molecular tests for CHIKV were performed. Blood samples were analyzed for anti-CHIKV IgG and IgM antibodies, and placental tissue was examined for CHIKV RNA and histological changes. Among pregnant patients, 1.33% (7/526) had reactive IgG, and 0.38% (2/526) had IgM/IgG-type antibodies during delivery. Although placental histology of CHIKV disease showed alterations, no viral genetic material was identified in the analyzed tissues. Therefore, further research is needed, including the use of complementary diagnostic techniques, to better understand the impact of this relatively new disease among high-risk pregnant women and newborns.

Abstract The objective of this study was to evaluate the spatial variability of soil attributes and the use of modeling to estimate forage production and carrying capacity (CC) in a semiarid region. Data were analyzed using geostatistical methods, including semivariograms analysis and mapping of each soil chemical attribute. Forage production was simulated at 99%; 95% and 90% guarantee levels, considering areas suitable for mechanized forage production, native pasture areas, irrigable areas and, ephemeral wetland areas. The exponential model best fit the attributes of organic matter, potassium, phosphorus, and pH, while the spherical model was optimal for base saturation, stoniness index, slope index, and general index. The Gaussian model provided the best fit for the cost index. Phosphorus had the lowest range (235 m) and demonstrated a strong spatial dependence (<25%). The highest forage production occurred in irrigable areas, with yields of 112,270.00, 178,661.00, and 215,455.00 kg year-1 at the 99%, 95%, and 90% guarantee levels, respectively. The 90% guarantee level enabled a 31% higher CC than the 99% level, with the highest CC observed in mechanized areas-accounting for about 71.8% of the property’s total CC due to greater forage production. Modeling effectively quantified areas capable of producing forage, with lower guarantee levels supporting higher forage production and carrying capacity.

Resumo O objetivo deste estudo foi avaliar a variabilidade espacial dos atributos do solo e o uso da modelagem para estimar a produção de forragem e capacidade de suporte (CS) no Semiárido. Os dados foram analisados usando métodos de geoestatística, incluindo semivariogramas e o mapeamento de cada atributo químico do solo estudado. A produção de forragem foi simulada para os níveis de garantia de 99; 95 e 90%, considerando áreas aptas à produção de forragem mecanizada, áreas de pastagem nativa, áreas irrigáveis e áreas de vazante. O modelo exponencial melhor se ajustou para os atributos matéria orgânica, potássio, fósforo e pH, enquanto o modelo esférico se ajustou para os atributos saturação por base, índice de pedregosidade, índice de declividade e índice geral. O modelo gaussiano melhor se ajustou para o índice de custo. O menor alcance (235 m) foi obtido para o fósforo, que apresentou um grau de dependência espacial classificado como forte (<25%). A maior produção de forragem foi obtida na área irrigável, com valores de 112.270,00; 178.661,00 e 215.455,00 kg ano-1 para os níveis de garantia 99; 95 e 90%, respectivamente. O nível de garantia de 90% possibilitou CS 31% superior à garantia de 99%, sendo maior a CS observada nas áreas mecanizadas, representando cerca de 71,8% da CS da propriedade, devido à maior produção de forragem. A modelagem permite quantificar eficientemente a área capaz de produzir forragem, sendo que menores níveis de garantia possibilitam maior produção de forragem e maior capacidade de suporte.

Resumen Objetivo. Caracterizar la distribución geográfica de dengue confirmado y evaluar su autocorrelación espacial con determinantes sociales y climáticos a nivel de áreas pequeñas, en dos ciudades del noroeste de México. Métodos. En este trabajo se utilizan herramientas de análisis espacial, como el Índice de Moran y el método de Indicadores Locales de Asociación Espacial (LISA), para examinar la correlación espacial, global y local, entre la incidencia de dengue y factores climáticos y socioeconómicos a nivel de área geoestadística básica (AGEB). Para mapear áreas de alto riesgo, se usó el método de agrupamiento espacial de Getis-Ord. Resultados. En general, no identificamos una autocorrelación espacial global, aunque agrupamientos locales de una alta incidencia de dengue, temperatura de la superficie terrestre ≤31 °C y un alto grado de marginación social, coinciden. Discusión. Encontramos que a nivel de áreas pequeñas urbanas, poblaciones con desventaja social agrupan una mayor carga de dengue comparadas con áreas de mejores condiciones socioeconómicas. En los dos sitios de estudio, se encontraron patrones espaciales similares que correlacionaron problemas de salud y características físicas del medio ambiente utilizando os análisis espaciales, lo que soporta la utilidad de su uso sistemático para entender mejor la distribución urbana del dengue.

Abstract Objective. To characterize the geographic distribution of dengue and to evaluate the spatial autocorrelation with social and climatic determinants at the census-tract level in two medium sized cities in northwestern Mexico. Methods. In this work we apply spatial analysis ecological tools, such as the Moran’s Index and the Local Indicator of Spatial Association (LISA) method, to examine global and local spatial correlation between incidence of dengue, with socioeconomic and climatic factors at the census tract-level. For the analysis of the spatial clustering, the Getis-Ord method was used to find statistically significant hot spots in each city. Results. Overall, a global spatial autocorrelation could not be identified, although local clusters of a high dengue incidence, soil surface temperature ≤ 31 °C and high degree of social marginalization coincide. Discussion. We found that at the census-tract level in urban settings, socially disadvantaged populations showed higher clusters of dengue when compared to areas with better socioeconomic conditions. A similar spatial pattern was observed in the two study sites, when considering public health conditions and its aggregation with physical attributes using spatial analysis techniques, supporting the application of this technique for a better understanding about the dengue distribution in urban areas.

Resumo A gestão florestal tradicional pós-fogo pode influenciar a vegetação futura do local e a recuperação da área ardida. O presente estudo, integrado no projeto SUDOE-REMAS (SOE3/P4/E0954) e na Unidade Curricular de Silvicultura II ministrada no Instituto Superior de Agronomia da Universidade de Lisboa, avaliou o efeito da gestão florestal na diversidade da vegetação pós-fogo no sobreiral da Serra do Caldeirão (Algarve, S de Portugal). A maioria dos solos são classificados como Leptossolos e o clima é do tipo Cs. Selecionaram-se parcelas de 3 tipos: não ardidas com gestão pós-fogo (A), ardidas com gestão pós-fogo (B) e ardidas sem gestão pós-fogo (C). Efetuaram-se inventários florísticos através de transeptos (15 transeptos por tipologia), com 10 m de comprimento cada, para avaliação da abundância e diversidade de espécies. Estimaram-se os índices de diversidade da série de Hill para os indivíduos inventariados. Os resultados indicaram que as parcelas do tipo C apresentam maior diversidade em todos os índices da Série de Hill. As parcelas A apresentaram maior diversidade quando comparadas com as parcelas B. A espécie Lavandula stoechas ssp. luisieri Rozeira é a espécie dominante nos 3 grupos (19% in plots A, 17% in B and 19% in C). Nas parcelas ardidas (B+C), Cistus ladanifer L. representa 14% dos indivíduos presentes, com ou sem gestão. Verificou-se maior presença de espécies pirófitas (géneros Cistus e Ulex) nas parcelas ardidas, com ou sem gestão. Este estudo aponta que o fogo pode favorecer a diversidade de espécies mas não a resistência das mesmas a novos fogos. Ainda assim, a gestão da flora herbácea nas parcelas ardidas parece influenciar positivamente a composição e diversidade.

Abstract Traditional post-fire forest management can influence future vegetation composition and recovery of a burned area. The present study, integrated in SUDOE-REMAS project (SOE3/P4/E0954) and Curricular Unit Silviculture II (Instituto Superior de Agronomia, Universidade de Lisboa), evaluated the effect of forest management on the diversity of post-fire vegetation in the cork oak forest from Serra do Caldeirão (Algarve, Portugal). Climate is classified as Csa and most of soils are Leptosols. We selected three types of cork oak plots: unburned (A), burned with post-fire management (B) and burned with post-fire abandonment (C). Floristic inventories were carried out through transects (15 transects per group and each one with 10 m of length ) to determine species abundance and diversity. Hill series diversity indices were estimated for the individuals inventoried. The results indicated that plots C present greater diversity in all Hill Series indices. Plots A presented greater diversity when compared to B. The species Lavandula stoechas ssp. luisieri Rozeira was the dominant in the 3 groups (19% in plots A, 17% in B and 19% in C). In the burned plots (B+C), Cistus ladanifer L. represented 14% of the total individuals, with or without management. In the unburned plots (A), Ulex argenteus Welw. ex Webb representes 17% of the individuals present. There’s a greater presence of pyrophytic species (genera Cistus and Ulex) in burned plots, with or without management. Fire is favourable to species diversity but not to their resistance to new fires. Nevertheless, management of herbaceous flora in burned plots seems to positively influence vegetation composition and diversity.

Abstract: Machine learning is a tool that is being used to optimize highly complex industrial processes. In the plywood panel production industry, veneer drying is one of the most important processes as it allows to obtain high quality products. The biological nature and high structural variability of wood turns its industrial processing multivariate and difficult to control. The large number of variables present and the increasing possibility to measure them in real time are enabling the availability of a large amount of data. Nowadays, data-driven approach and Intelligence Artificial techniques, specifically Machine Learning can enable robust prediction and control approaches. In the process industry, with high levels of automation, it is possible to enable decision making to predict product quality by monitoring explanatory control variables. The objective of this work was to evaluate a Machine Learning algorithm capable of predicting the quality of the veneer drying process from a considerable number of input variables captured from a real industrial process. The Weka platform and Python code were used. Three algorithms were evaluated: K-Nearest-Neighbor, eXtreme Gradient Boosting and Support Vector Machine. Variable and dimensionality reduction, correlation analysis and Principal Component Analysis were performed. The results showed that eXtreme Gradient Boosting achieved an accuracy of 76 % in predicting quality scores. Finally, it is concluded that both the data engineering methodology and the evaluated algorithms were efficient in predicting industrial data.

Resumen: El Aprendizaje automático o Machine learning es una herramienta que está siendo utilizada para optimizar procesos industriales de alta complejidad. En la industria de producción de paneles contrachapados, el secado de chapas es uno de los procesos más importantes ya que permite obtener productos con alta calidad. La naturaleza biológica y alta variabilidad estructural de la madera hace que su procesamiento industrial sea multivariado y difícil de controlar. La gran cantidad de variables presentes y la posibilidad cada vez más frecuente de medirlas en tiempo real están permitiendo la disponibilidad de una gran cantidad de datos. En la actualidad, el enfoque basado en datos y las técnicas de Inteligencia Artificial, específicamente Machine learning, pueden permitir enfoques robustos de predicción y de control. En la industria de procesos con altos niveles de automatización es posible viabilizar la toma de decisiones para predecir la calidad del producto, monitoreando las variables de control explicativas. El objetivo de este trabajo fue evaluar el comportamiento de tres algoritmos de Machine learning para predecir la calidad del proceso de secado de chapas a partir de un número considerable de variables de entrada capturadas de un proceso industrial real. Se utilizó la plataforma Weka y código Python. Se evaluaron los algoritmos: K-Nearest-Neighbor, eXtreme Gradient Boosting y Support Vector Machine. Se realizó reducción de variables y dimensionalidad de análisis de correlación y de componentes principales. Los resultados demostraron que eXtreme Gradient Boosting logró una precisión del 76 % en la predicción de resultados de calidad. Finalmente, se concluye que la metodología de ingeniería de datos y los algoritmos fueron eficientes para predecir los datos industriales.

Abstract Introduction Ileostomy formation is performed for multiple purposes related to intestinal pathology, such as obstructive malignant or benign tumors, inflammatory bowel diseases, intestinal ischemia, and, for the most part, as a protective stoma in high-risk anastomosis. The creation of this surgical opening, despite being considered a simple procedure, is undoubtedly followed by complications in certain cases. Materials and Methods We conducted an electronic literature search in the MEDLINE database using the PubMed search engine. A total of 43 articles were included in the present review. Results/Discussion Over the course of the present work, we were able to explore different types of complications that can arise in patients with an ileostomy. High-output stomas were found to be associated with dehydration and electrolyte imbalance. Skin-related morbidity was shown to be present in a great percentage of patients. More severe complications, such as peristomal pyoderma gangrenosum and necrosis, are less frequent and require urgent management. Several risk factors were identified in cases of retraction, obstruction, prolapse, and parastomal herniation. Conclusion Even though ileostomies may present numerous benefits in certain patients, they are also associated with many complications, which should be avoided and quickly managed, because they can severely affect the quality of life of the patients. Surveillance and follow-up by a multidisciplinary team is strongly advisable, bearing in mind that a good performance on the part of the responsible surgeon is also a key factor.
