ABSTRACT Study Plan E in the Bachelor's Degree in Agricultural Education has Investigative Work Training as its main integrating discipline and brings together the contents of the exercise of the profession, the Educational Research Methodology and Agricultural Didactics. In the exploratory study, weaknesses were observed related to the planning, orientation, execution and evaluation of teaching tasks with an interdisciplinary nature for the solution of professional problems and these do not always stimulate students to search, investigate and problematize the content they they learn. . For this reason, this article aimed to socialize methodological indications for the treatment of interdisciplinarity in integrative teaching tasks and its contribution to the development of modes of action harmonizing different systems of influences according to educational contexts. The general dialectical-materialist method was used, as well as theoretical level methods such as: historical-logical analysis, induction-deduction and analysis-synthesis. At the empirical level, the review of documents, the survey, the interview, performance observation and visits to the work practice were used. A workshop was held to validate the methodological indications for their practical assessment. This result was introduced five years ago in Pinar del Río, showing satisfactory partial results in the integrative exams applied.

RESUMEN El Plan de Estudio E en la carrera Licenciatura en Educación Agropecuaria tiene como disciplina principal integradora la Formación Laboral Investigativa y agrupa los contenidos del ejercicio de la profesión, la Metodología de la Investigación Educativa y la Didáctica Agropecuaria. En el estudio exploratorio se observaron debilidades relacionadas con la planificación, orientación, ejecución y evaluación de tareas docentes con carácter interdisciplinar para la solución de problemas profesionales; estas no siempre estimulan a los estudiantes a la búsqueda, indagación y problematización del contenido que aprenden. Es por ello que este artículo tuvo como objetivo socializar indicaciones metodológicas para el tratamiento de la interdisciplinariedad en tareas docentes integradoras y su contribución al desarrollo de modos de actuación, armonizando diferentes sistemas de influencias según los contextos educativos. Se empleó como método general el dialéctico-materialista, así como métodos del nivel teórico: el análisis histórico-lógico, la inducción-deducción y el análisis-síntesis. Del nivel empírico se empleó la revisión de documentos, la encuesta, la entrevista, la observación del desempeño y visitas a la práctica laboral. Se realizó un taller de validación de las indicaciones metodológicas para su valoración práctica. Este resultado se introduce hace cinco años en Pinar del Río, mostrando resultados parciales satisfactorios en los exámenes integradores aplicados.

RESUMEN El significado del término psicometría se puede abordar desde distintas perspectivas, tales como la consulta de diccionarios, el punto de vista de expertos internacionales o el análisis de un corpus lingüístico. Para este estudio, se ha partido de un corpus actualizado del español. La muestra fue de 90 documentos válidos de los que se seleccionó el primer texto de modo que las frecuencias de los temas procedieran de textos independientes. El método empleado fue el análisis temático tabular estructurado (AT-TE). Los resultados indican que la acepción más frecuente en español es la relativa al análisis de la calidad de las medidas, seguida de la que refiere a la evaluación y finalmente la de un enfoque metodológico en general, lo que es coherente con los diccionarios de autoridades, pero se aleja de la perspectiva mayoritaria de expertos internacionales, que consideran que la psicometría no tendría por qué vincularse a la psicología.

ABSTRACT Understanding the meaning of the term psychometrics can be approached from different perspectives, such as the consultation of dictionaries, the point of view of international experts, or the analysis of a linguistic corpus. For this study, an up-to-date Spanish corpus was used as the starting point. The sample consisted of 90 valid documents from which the first text was selected so that the frequencies of the themes came from independent texts. The method used was structured tabular thematic analysis (ST-TA). The results indicate that the most frequent meaning in Spanish is that related to the analysis of the quality of measurements, followed by that referring to evaluation, and finally that of a methodological approach in general. This is consistent with the dictionaries of authorities, but departs from the majority perspective of international experts, who consider that psychometrics does not necessarily have to be linked to psychology.

Resumen Antecedentes: En los pseudoaneurismas infectados de arteria femoral asociados al uso de drogas intravenosas, la ligadura primaria para el tratamiento causa controversia, sin embargo, el territorio comprometido puede continuar irrigado por vías colaterales. Objetivo: Reportar la experiencia del manejo de pseudoaneurismas en un servicio de angiología y cirugía vascular. Métodos: Estudio observacional, descriptivo de una serie de casos. Resultados: Se reportan 15 pacientes, relación hombre: mujer 14:1, promedio de edad de 42 años. Siete (46.6%) con presentación de pseudoaneurisma femoral izquierdo, 5 (33.3%) de ellos con presentación de pseudoaneurisma femoral derecho, 2 (13.3%) con pseudoaneurisma humeral derecho y uno (6.6%) con pseudoaneurisma humeral izquierdo. En 12 se realizó exclusión del pseudoaneurisma con triple ligadura; y 3 pacientes fueron sometidos a revascularización. Conclusiones: En nuestra experiencia, la ligadura primaria sin revascularización tuvo incidencia de amputación baja y supervivencia alta de los pacientes afectados, siendo la claudicación la secuela más frecuente.

Abstract Background: In intravenous drug-infected femoral pseudoaneurysms, primary ligation for treatment is controversial, but the compromised territory can remain irrigated by collateral routes. Objective: To report the experience in the management of pseudoaneurysms in our angiology and vascular surgery service. Methods: Observational, descriptive study of a series of cases. Results: 15 patients are reported, male: female ratio 14:1, average age 42 years. Seven (46.6%) presented with a left femoral pseudoaneurysm, 5 (33.3%) presented with a right femoral pseudoaneurysm, 2 (13.3%) with a right brachial pseudoaneurysm, and one (6.6%) with a left brachial pseudoaneurysm. In 12, exclusion of the pseudoaneurysm was performed with triple ligation; 3 patients underwent revascularization. Conclusions: In our experience the primary ligature without revascularization has a low incidence of amputation and high survival of affected patients, being claudication the most frequent sequel.

Abstract Orthodontics patients usual develop demineralization and present cavity caries lesions after six months. Minimally invasive procedures have been the goal in modern dental practice. The aim of this study was to evaluate the effect of ClinproTMXT Varnish, on the enamel surface roughness and severity of white spot lesions. Twenty premolars were submitted to bond brackets and experimental induction of demineralization and randomly divided into 2 groups: GI - fluoride varnish (Colgate Duraphat®); GII - Ionomeric Sealant (ClinproTMXT Varnish). The treatment was applied around the brackets. The surface roughness of specimens was analyzed, before treatment and 12 weeks after treatment by laser confocal microscopy, and the severity of the white spot lesion was by laser fluorescence device. The data were analyzed by non-parametric Wilcoxon and Mann-Whitney Test, at 5% significance, roughness percentage reduction was performed. The severity of demineralization decreased in both, GI (p = 0.005) and GII (p = 0.019). Enamel superficial roughness levels decreased in GI and GII. As well as the roughness percentage, being more expressive in the ClinproTMXT Varnish group (85,09%). Colgate Duraphat® or Clinpro™ XT Varnish reduced the severity of the demineralization and decreased the superficial roughness on the enamel. The Clinpro™ XT Varnish was superior to superficial roughness on enamel.

Resumo Pacientes ortodônticos geralmente desenvolvem desmineralização e apresentam lesões de cárie após seis meses de tratamento. Procedimentos minimamente invasivos têm sido o objetivo na prática odontológica moderna. O objetivo deste estudo foi avaliar o efeito do ClinproTM XT selante ionomérico, ao redor do bráquete, com relação a rugosidade superficial do esmalte e a severidade da lesão induzida. Vinte pré-molares foram submetidos a colagem de bráquetes e indução experimental de desmineralização e divididos aleatoriamente em 2 grupos: GI - verniz fluoretado (Colgate Duraphat®); GII - Selante Ionomérico (ClinproTM XT). O tratamento foi aplicado ao redor dos bráquetes. A rugosidade da superfície dos espécimes foi analisada, antes do tratamento e 12 semanas após o tratamento por microscopia confocal a laser e severidade da lesão de mancha branca por dispositivo de fluorescência a laser. Os dados foram analisados pelo teste não paramétrico de Wilcoxon e Mann-Whitney, a 5% de significância. A taxa de redução da lesão foi calculada. A severidade da desmineralização diminuiu tanto no GI (p = 0,005) quanto no GII (p = 0,019). Os níveis de rugosidade superficial do esmalte diminuíram no GI e GII, assim como o percentual de rugosidade, sendo mais expressivo no grupo ClinproTMXT (85,09%). Colgate Duraphat® e Clinpro™ XT reduziram a severidade da desmineralização e diminuíram a rugosidade superficial do esmalte. O selante ionomérico Clinpro™ XT foi superior na redução percentual de rugosidade.

ABSTRACT Introduction: The frailty syndrome in dialysis patients can deteriorate the health-related quality of life. Objective: To analyze the association between frailty syndrome and health-related quality of life in patients undergoing continuous ambulatory peritoneal dialysis. Materials and Method: A descriptive cross-sectional study was conducted in Mexico City. The convenience sample included 106 patients from the peritoneal dialysis program, of which 62% were male. Age, marital status, occupation, education level, body mass index, creatinine, and albumin were recorded. Health-related quality of life was assessed using KDQOL SF-36 and frailty syndrome through the Short Physical Performance Battery (SPPB). Results: SPPB scores showed a significant correlation with certain categories of KDQOL SF-36, such as kidney disease effects, kidney disease burden, and physical components. Gait speed test scores were not associated with any category of KDQOL SF-36. There were also no associations between the scores obtained in the mental component of KDQOL SF-36 and those of the SPPB tests. Health-related quality of life was lower in patients with frailty, advanced age, or hypoalbuminemia. Conclusions: Patients undergoing peritoneal dialysis have a high prevalence of frailty syndrome and decreased quality of life. Furthermore, the high frailty rate is associated with poorer quality of life, especially in physical performance.

RESUMEN Introducción: El síndrome de fragilidad en pacientes en diálisis puede deteriorar la calidad de vida relacionada con la salud. Objetivo: Analizar la asociación entre el síndrome de fragilidad y la calidad de vida relacionada con la salud en pacientes en diálisis peritoneal continua ambulatoria. Material y Método: Estudio descriptivo de corte transversal, realizado en la Ciudad de México. La muestra por conveniencia incluyó a 106 pacientes del programa de diálisis peritoneal, de los cuales 62% eran hombres. Se registraron edad, estado civil, ocupación, escolaridad, índice de masa corporal, creatinina y albumina. La calidad de vida relacionada con la salud se evaluó con KDQOL SF-36 y la fragilidad mediante la Batería Corta de Rendimiento Físico (BCRF). Resultados: Las puntuaciones de la BCRF mostraron correlación significativa con ciertas categorías de KDQOL SF-36, como efectos de la enfermedad renal, carga de la enfermedad renal y componente físico. Las puntuaciones de la prueba de velocidad de marcha no se asociaron a ninguna categoría de KDQOL SF-36. Tampoco hubo asociaciones entre las puntuaciones obtenidos en el componente mental de KDQOL SF-36 y los de las pruebas de la BCRF. La calidad de vida relacionada con la salud fue menor en los pacientes con fragilidad, edad avanzada o hipoalbuminemia. Conclusiones: Los pacientes en diálisis peritoneal tienen una alta prevalencia del síndrome de fragilidad y disminución de la calidad de vida. Además, la alta tasa de fragilidad está asociada a peor calidad de vida, especialmente en el rendimiento físico.

ABSTRACT Objective To estimate the prevalence of syphilis and its associated factors in women who were treated at public maternity hospitals and received prenatal care in a primary healthcare unit. Methods This cross-sectional study included 399 postpartum women. Interviews were conducted, and additional data were extracted from the pregnant woman’s booklet, medical records, and printed tests. The dependent variable was a gestational syphilis diagnosis. The independent variables were grouped into socioeconomic and demographic, behavioral, reproductive, and prenatal blocks. The prevalence, prevalence ratios, and 95% confidence intervals (95%CI) were calculated. The χ 2 test was also performed (p≤0.05). Multivariate analysis was performed using Poisson regression models. Results The prevalence of gestational syphilis was 9.61% (95%CI: 7.14-12.83). We identified the following determining factors (adjusted prevalence ratios): history of sexually transmitted infections (2.3), first sexual intercourse by the age of 15 (2.42), partner having a history of syphilis (5.98), partner using crack/cocaine (6.42) and marijuana and others (3.02), not having a partner (3.07), low income (2.85), history of stillbirth (5.21), beginning prenatal care in the third trimester (3.15), and prenatal care received in a primary healthcare unit (without a Family Health Strategy team) (0.35). Conclusion Individual and prenatal factors were associated with gestational syphilis. To control congenital syphilis, targeted interventions are needed to control syphilis in the adult population including expansion of access to quality prenatal care with identification of risks for syphilis and connection between prevention and treatment actions, implementation of strategies focused on early sexual education, effective establish prenatal care involving both partners, and effective implementation of the National Men’s Health Policy (PNAISH - Política Nacional de Atenção Integral à Saúde dos Homens ).

Numerical simulation was used to predict the thermal behavior and the resulting microstructure at the heat-affected zone (HAZ) of a 170 mm diameter and 3.5 mm thickness super duplex stainless steel (SDSS) UNS S32750 tube. In order to evaluate the thermal response from the model, a usual welding situation involving interpass temperature (IT) and its influence on the HAZ microstructure was exploited. Thus, two superimposed autogenous welding passes were simulated, the first clockwise with the tube in the room temperature and the second, counterclockwise, with the tube at the temperature of 250oC. Even subjected to successive thermal cycles and high interpass temperature, the proportion and morphology of the phases at the HAZ and Fusion Zone (FZ) did not present significant differences when comparing the two welding passes. Meanwhile, nitrogen losses should be avoided during welding in order to obtain a balanced microstructure in DSS welds, contributing to guarantee satisfactory toughness in addition to resistance to pitting corrosion. The predictions from the simulation were validated by using experimental results obtained from the autogenous TIG (Tungsten Inert Gas) process.

Abstract Fluoride (F) has been widely used to control dental caries, and studies suggest beneficial effects against diabetes when a low dose of F is added to the drinking water (10 mgF/L). Objectives This study evaluated metabolic changes in pancreatic islets of NOD mice exposed to low doses of F and the main pathways altered by the treatment. Methodology In total, 42 female NOD mice were randomly divided into two groups, considering the concentration of F administered in the drinking water for 14 weeks: 0 or 10 mgF/L. After the experimental period, the pancreas was collected for morphological and immunohistochemical analysis, and the islets for proteomic analysis. Results In the morphological and immunohistochemical analysis, no significant differences were found in the percentage of cells labelled for insulin, glucagon, and acetylated histone H3, although the treated group had higher percentages than the control group. Moreover, no significant differences were found for the mean percentages of pancreatic areas occupied by islets and for the pancreatic inflammatory infiltrate between the control and treated groups. Proteomic analysis showed large increases in histones H3 and, to a lesser extent, in histone acetyltransferases, concomitant with a decrease in enzymes involved in the formation of acetyl-CoA, besides many changes in proteins involved in several metabolic pathways, especially energy metabolism. The conjunction analysis of these data showed an attempt by the organism to maintain protein synthesis in the islets, even with the dramatic changes in energy metabolism. Conclusion Our data suggests epigenetic alterations in the islets of NOD mice exposed to F levels comparable to those found in public supply water consumed by humans.

ABSTRACT There is a need for greater knowledge about the medium- and long-term effects of prescribed fire management on soil in ecosystems prone to wildfires and more vulnerable to climate change. This study examined the short- and medium-term effects of prescribed fire on soil chemical properties and chemical fractions of soil organic matter (SOM) in two positions of the landscape in a high-elevation grassland environment. The ecosystem is located in the mountain peaks of southeastern Brazil associated with the Atlantic Forest biome. Prescribed fire was conducted in 2017 to reduce understory vegetation and thus prevent potential severe wildfires. Soil samples were collected at the layers of 0.00-0.10, 0.10-0.20, and 0.20-0.40 m, at eight composite sampling. The composite samples were collected on five different occasions: before the prescribed fire, and 10, 30, 90, and 240 days after the prescribed fire. Soil chemical properties, total organic carbon, labile C, and chemical fractionation of SOM were analyzed. All soil properties investigated were affected by the prescribed fire, with variations in landscape position, duration of effect, and soil layer. In the backslope area, the medium-term effect of fire was negative and induced soil degradation and induced soil degradation. In the footslope area, the system showed greater resilience to the effects of fire, as indicated by the recovery of the soil’s chemical properties. These results can help assess the suitability of controlled burning of vegetation for managing risks of fire in mountainous regions, such as high-elevation grasslands.

Abstract Objectives The present study aimed to evaluate the measurement invariance of a general measure of the perception of governmental responses to COVID-|19 (COVID-SCORE-10) in the general population of 13 Latin American countries. Methods A total of 5780 individuals from 13 Latin American and Caribbean countries selected by non-probabilistic snowball sampling participated. A confirmatory factor analysis was performed and the alignment method was used to evaluate invariance. Additionally, a graded response model was used for the assessment of item characteristics. Results The results indicate that there is approximate measurement invariance of the COVID-SCORE-10 among the participating countries. Furthermore, IRT results suggest that the COVID-SCORE-10 measures with good psychometric ability a broad spectrum of the construct assessed, especially around average levels. Comparison of COVID-SCORE-10 scores indicated that participants from Cuba, Uruguay and El Salvador had the most positive perceptions of government actions to address the pandemic. Thus, the underlying construct of perception of government actions was equivalent in all countries. Conclusion The results show the importance of initially establishing the fundamental measurement properties and MI before inferring the cross-cultural universality of the construct to be measured.

ABSTRACT Background: The coronavirus disease (COVID-19) is an infectious disease caused by the SARS-CoV-2 virus and is responsible for nearly 6 million deaths worldwide in the past 2 years. Machine learning (ML) models could help physicians in identifying high-risk individuals. Objectives: To study the use of ML models for COVID-19 prediction outcomes using clinical data and a combination of clinical and metabolic data, measured in a metabolomics facility from a public university. Methods: A total of 154 patients were included in the study. “Basic profile” was considered with clinical and demographic variables (33 variables), whereas in the “extended profile,” metabolomic and immunological variables were also considered (156 characteristics). A selection of features was carried out for each of the profiles with a genetic algorithm (GA) and random forest models were trained and tested to predict each of the stages of COVID-19. Results: The model based on extended profile was more useful in early stages of the disease. Models based on clinical data were preferred for predicting severe and critical illness and death. ML detected trimethylamine N-oxide, lipid mediators, and neutrophil/lymphocyte ratio as important variables. Conclusion: ML and GAs provided adequate models to predict COVID-19 outcomes in patients with different severity grades.

Abstract Objective: Pediatric acute liver failure (PALF) is a heterogeneous, rare, and severe condition, which outcome is survival due to liver spontaneous recovery or death. The patients who do not recover may be allocated to liver transplantation, which is the standard treatment. This study aimed to build a prognostic model to support the clinical decision to indicate liver transplantation for patients with PALF in a Brazilian center. Methods: The authors retrospectively analyzed the clinical variables of 120 patients in the liver transplantation program of the 'Children's Institute of the University of São Paulo, Brazil. The authors conducted a univariate analysis of variables associated with survival in PALF. Logistic multivariate analysis was performed to find a prognostic model for the outcome of patients with pediatric acute liver failure. Results: Risk factors were analyzed using univariate analysis. Two prognostic models were built using multiple logistic regression, which resulted in 2 models: model 1(INR/ALT) and model 2 (INR/Total bilirubin). Both models showed a high sensitivity (97.9%/96.9%), good positive predictive value (89.5%/90.4%), and accuracy (88.4%/88.5%), respectively. The receiver operating characteristic was calculated for both models, and the area under the curve was 0.87 for model 1 and 0.88 for model 2. The Hosmer-Lemeshow test showed that model 1 was good. Conclusion: The authors built a prognostic model for PALF using INR and ALT that can contribute to the clinical decision to allocate patients to liver transplantation.
