ABSTRACT Introduction: Arterial hypertension is a disease of high prevalence and fatal complications. Due to this, an adequate management is needed in the primary care, and also preventive and intervention strategies, as the HEARTS initiative in the Americas. It is also known that there is a high prevalence of hypertensive patients among the working staff of the Matanzas University of Medical Sciences. Objective: To identify the behavior of disease control and global cardiovascular risk stratification. Materials and methods: Cross-sectional descriptive study in which the first 80 hypertensive patients evaluated in the consultation of the aforementioned institution were included. The methods used were analytical-synthetic, inductive-deductive, historical-logical and statistical. Results: Of 808 workers, 276 were hypertensive, for a prevalence of 34.1%. Among the inadequate lifestyles, sedentary lifestyle predominated, with 59 patients (73.7%); 40 of the 80 patients studied had a quantitative cardiovascular risk equal to or greater than 10%, while qualitative cardiovascular risk showed that 68 (85%) had a medium or high risk. Cardiovascular diseases predominated within target organ damage, with 16.2%. Conclusions: Arterial hypertension continuous to be one of the most important risk factors for cardiovascular and cerebrovascular diseases. Its screening, control and risk assessment are a priority of the medical care at the primary level.

RESUMEN Introducción: La hipertensión arterial es una enfermedad de alta prevalencia y complicaciones mortales. Debido a ello, se necesitan un adecuado manejo en la atención primaria y estrategias preventivas y de intervención, como la iniciativa HEARTS en las Américas. Se sabe también que entre los trabajadores de la Universidad de Ciencias Médicas de Matanzas existe una elevada prevalencia de hipertensos. Objetivo: Identificar el comportamiento del control de la enfermedad y la estratificación de riesgo cardiovascular global. Materiales y métodos: Estudio descriptivo transversal en el que se incluyeron los primeros 80 pacientes hipertensos valorados en la consulta de la mencionada institución. Los métodos empleados fueron el analítico-sintético, el inductivo-deductivo, el histórico-lógico y los estadísticos. Resultados: De 808 trabajadores, 276 eran hipertensos, para una prevalencia de 34,1 %. Dentro de los inadecuados estilos de vida, predominó el sedentarismo, con 59 pacientes (73,7 %); 40 de los 80 pacientes estudiados tenían un riesgo cardiovascular cuantitativo igual o mayor del 10 %, mientras que el riesgo cardiovascular cualitativo mostró que 68 (85 %) tenían un riesgo medio o alto. Dentro del daño en órganos diana predominaron las enfermedades cardiovasculares, con un 16,2 %. Conclusiones: La hipertensión arterial sigue siendo uno de los factores de riesgo más importantes de enfermedad cardiovascular y cerebrovascular.

Abstract Objective To compare cytological and histological results from women > 64 years old who followed the Brazilian national cervical cancer screening guidelines with those who did not. Methods The present observational retrospective study analyzed 207 abnormal cervical smear results from women > 64 years old in a mid-sized city in Brazil over 14 years. All results were reported according to the Bethesda System. The women were divided into those who followed the screening guidelines and those who did not. Results Atypical squamous cells of undetermined significance and low-grade squamous intraepithelial lesion cytology results were found in 128 (62.2%) cases. Of these, 112 (87.5%) had repeated cytology with positive results. The other 79 (38.1%) with abnormal results should have been referred to colposcopy and biopsy. Out of 41 (51.9%) biopsied women, 23 (29.1%) had a confirmed diagnosis of neoplasia or precursor lesion. In contrast, among the 78 (37.7%) biopsied patients, 40 (51.3%) followed the guideline recommendations, with 9 (22.5%) positive biopsies. Of the 38 (48.7%) women who did not follow the guidelines, there were 24 (63.1%) positive results. Women who did not follow the guidelines demonstrated higher chances of cancer and precursor lesions (odds ratio [OR]: 5.904; 95% confidence interval [CI]: 2.188–15.932; p = 0.0002). Conclusion Women > 64 years old who did not follow the national screening protocol showed significant differences in the frequency of abnormal results and severity of diagnosis compared with those who followed the protocol.

Resumo Objetivo Comparar os resultados citológicos e histológicos de mulheres > 64 anos que seguiram as diretrizes nacionais brasileiras de rastreamento do câncer do colo do útero com aquelas que não as seguiram. Método O presente estudo observacional retrospectivo analisou 207 resultados anormais de esfregaço cervical de mulheres > 64 anos de idade em uma cidade de médio porte no Brasil durante 14 anos. Todos os resultados foram relatados de acordo com o Sistema Bethesda. As mulheres foram divididas entre as que seguiram as diretrizes de rastreamento e as que não o fizeram. Resultados Resultados citológicos com células escamosas atípicas de significado indeterminado e lesão intraepitelial escamosa de baixo grau foram encontrados em 128 (62,2%) casos. Destes, 112 (87,5%) repetiram a citologia com resultados positivos. Os outros 79 (38,1%) com resultados anormais deveriam ter sido encaminhados para colposcopia e biópsia. Das 41 (51,9%) mulheres biopsiadas, 23 (29,1%) tiveram diagnóstico confirmado de neoplasia ou lesão precursora. Em contrapartida, entre as 78 (37,7%) pacientes biopsiadas, 40 (51,3%) seguiram as recomendações da diretriz, com 9 (22,5%) biópsias positivas. Entre as 38 (48,7%) mulheres que não seguiram as orientações, houve 24 (63,1%) resultados positivos. As mulheres que não seguiram as diretrizes demonstraram maiores chances de câncer e lesões precursoras (odds ratio [OR]: 5,904; intervalo de confiança [IC] de 95%: 2,188–15,932; p = 0,0002). Conclusão Mulheres > 64 anos que não seguiram a diretriz nacional de rastreamento apresentaram diferenças significativas na frequência de resultados anormais e gravidade do diagnóstico em comparação com aquelas que seguiram a diretriz.

Abstract Objective: to analyze the psychosocial impacts of the COVID-19 pandemic among Brazilian women from rural settlements. Method: this is a quantitative and longitudinal study conducted with 13 settled women. The data were collected between January 2020 and September 2021 using questionnaires on the perception of the social environment (quality of life, social support, self-efficacy), common mental disorder symptoms and sociodemographic aspects. The data were analyzed using descriptive statistics, cluster analysis and variance analysis. Results: intersecting vulnerability conditions were identified that possibly intensified the challenges arising from the pandemic. The Quality of Life physical domain fluctuated differently and inversely according to the mental disorder symptoms. As for the psychological domain, at the end of the segment, an increase over time was identified in the entire sample, as the women’s perception was better than before the pandemic. Conclusion: worsening of the participants’ physical health deserves to be highlighted and, probably, it can be related to the difficulty accessing health services in this period as well as to the fear of contamination. Despite this, the participants were emotionally resilient throughout the period, including signs of improvement in terms of psychological aspects, suggesting a possible effect of the community organization of the settlement.

Resumen Objetivo: analizar los impactos psicosociales de la pandemia de COVID-19 en mujeres brasileñas de asentamientos rurales. Método: se trata de un estudio longitudinal cuantitativo con 13 mujeres asentadas. Los datos se recolectaron entre enero de 2020 y septiembre de 2021 mediante cuestionarios sobre percepción del entorno social (calidad de vida, apoyo social, autoeficacia), síntomas de trastorno mental común y aspectos sociodemográficos. Los datos se analizaron mediante estadística descriptiva, análisis de conglomerados y análisis de varianza. Resultados: se identificaron condiciones de vulnerabilidad entrelazadas que posiblemente exacerbaron los desafíos impuestos por la pandemia. El dominio físico de la calidad de vida fluctuó de manera diferente e inversa de acuerdo a los síntomas del trastorno mental. En cuanto al dominio psicológico, al final del segmento, se identificó un aumento en el tiempo en toda la muestra, dado que la percepción de las mujeres era mejor que antes de la pandemia. Conclusión: hay que destacar el empeoramiento de la salud física de las participantes que, probablemente, puede estar relacionado con la dificultad para acceder a los servicios de salud durante ese período y el miedo al contagio. A pesar de eso, las participantes fueron resilientes emocionalmente durante todo el período e, inclusive, tuvieron signos de mejoría en los aspectos psicológicos, lo que sugiere un posible efecto de la organización comunitaria del asentamiento.

Resumo Objetivo: analisar os impactos psicossociais da pandemia de COVID-19 entre mulheres brasileiras de assentamentos rurais. Método: trata-se de um estudo quantitativo longitudinal com 13 mulheres assentadas. Os dados foram coletados entre janeiro de 2020 e setembro de 2021 utilizando questionários sobre a percepção do ambiente social (qualidade de vida, apoio social, autoeficácia), sintomas de transtorno mental comum e aspectos sociodemográficos. Os dados foram analisados por meio de estatística descritiva, análise de agrupamento e de variância. Resultados: foram identificadas condições de vulnerabilidade interseccionadas que, possivelmente, exacerbaram os desafios decorrentes da pandemia. O domínio físico da qualidade de vida oscilou diferentemente e inversamente de acordo com os sintomas de transtorno mental. Quanto ao domínio psicológico, no final do segmento, identificou-se em toda a amostra um incremento ao longo do tempo, pois a percepção das mulheres estava melhor do que antes da pandemia. Conclusão: a piora na saúde física das participantes merece destaque e, provavelmente, pode estar relacionada à dificuldade de acesso aos serviços de saúde neste período bem como ao medo da contaminação. Apesar disso, as participantes apresentaram-se emocionalmente resilientes em todo o período, inclusive, com sinais de melhora em relação aos aspectos psicológicos, sugerindo um possível efeito da organização comunitária do assentamento.

Abstract Objective To evaluate the impact of the race (Black versus non-Black) on maternal and perinatal outcomes of pregnant women with COVID-19 in Brazil. Methods This is a subanalysis of REBRACO, a Brazilian multicenter cohort study designed to evaluate the impact of COVID-19 on pregnant women. From February2020 until February 2021, 15 maternity hospitals in Brazil collected data on women with respiratory symptoms. We selected all women with a positive test for COVID-19; then, we divided them into two groups: Black and non-Black women. Finally, we compared, between groups, sociodemographic, maternal, and perinatal outcomes. We obtained the frequency of events in each group and compared them using X2 test; p-values < 0.05 were considered significant. We also estimated the odds ratio (OR) and confidence intervals (CI). Results 729 symptomatic women were included in the study; of those, 285 were positive for COVID-19, 120 (42.1%) were Black, and 165 (57.9%) were non-Black. Black women had worse education (p = 0.037). The timing of access to the health system was similar between both groups, with 26.3% being included with seven or more days of symptoms. Severe acute respiratory syndrome (OR 2.22 CI 1.17–4.21), intensive care unit admission (OR 2.00 CI 1.07–3.74), and desaturation at admission (OR 3.72 CI 1.41–9.84) were more likely to occur among Black women. Maternal death was higher among Black women (7.8% vs. 2.6%, p = 0.048). Perinatal outcomes were similar between both groups. Conclusion Brazilian Black women were more likely to die due to the consequences of COVID-19.

Resumo Objetivo Avaliar o impacto da raça (negra versus não negra) nos desfechos maternos e perinatais de gestantes com COVID-19 no Brasil. Métodos Esta é uma subanálise da REBRACO, um estudo de coorte multicêntrico brasileiro desenhado para avaliar o impacto da COVID-19 em mulheres grávidas. De fevereiro de 2020 a fevereiro de 2021, 15 maternidades do Brasil coletaram dados de mulheres com sintomas respiratórios. Selecionamos todas as mulheres com teste positivo para COVID-19; em seguida, as dividimos em dois grupos: mulheres negras e não negras. Finalmente, comparamos, entre os grupos, os resultados sociodemográficos, maternos e perinatais. Obtivemos a frequência dos eventos em cada grupo e comparamos usando o teste X2; Valores de p <0,05 foram considerados significativos. Também estimamos o odds ratio (OR) e os intervalos de confiança (IC). Resultados 729 mulheres sintomáticas foram incluídas no estudo; desses, 285 foram positivos para COVID-19, 120 (42,1%) eram negros e 165 (57,9%) não eram negros. As mulheres negras apresentaram pior escolaridade (p = 0,037). O tempo de acesso ao sistema de saúde foi semelhante entre os dois grupos, com 26,3% incluídos com sete ou mais dias de sintomas. Síndrome respiratória aguda grave (OR 2,22 CI 1,17–4,21), admissão em unidade de terapia intensiva (OR 2,00 CI 1,07–3,74) e dessaturação na admissão (OR 3,72 CI 1,41–9,84) foram mais prováveis de ocorrer entre mulheres negras. A mortalidade materna foi maior entre as negras (7,8% vs. 2,6%, p = 0,048). Os resultados perinatais foram semelhantes entre os dois grupos. Conclusão Mulheres negras brasileiras tiveram maior probabilidade de morrer devido às consequências da COVID-19.

Resumen: El objetivo de este estudio es evaluar los efectos de la sustitución parcial de grasa por almidón de yuca y fibra de arveja (Pisum sativum L.) en salchichones fermentados. Se analizan las propiedades texturales, microbiológicas, sensoriales y microestructurales utilizando un cultivo iniciador compuesto de Staphylococcus xylosus y Lactobacillus sakei. Se aplica un diseño factorial aleatorio. Los resultados muestran que el almidón de yuca tuvo mayor efecto en la dureza, debido a que se presentaron los valores más altos cuando fue adicionado en mayor proporción (50 %). Los recuentos de microorganismos están dentro de los límites establecidos por la Norma Técnica Colombiana (NTC-1325 del 20-08-2008) de 2008 para salchichones. Se concluye que la fibra de arveja y el almidón de yuca favorecen la microbiota de salchichones, logrando ser ingredientes importantes en la formulación de salchichones fermentados a partir del desarrollo de nuevos productos a nivel industrial.

Abstract: The main objective of this study is to evaluate the effects of partially substituting fermented salchichón fat with cassava starch and pea fiber (Pisum sativum L.). The analyses examine the textural, microbiological, sensory, and microstructural properties. A starter culture with Staphylococcus xylosus and Lactobacillus sakei is used and a factorial random design is applied. The results show that cassava starch has the most effect on hardness since the highest values are obtained when it is added in high proportions (50%). Microbial counts are within the limits established by the 2008 Colombian Technical Standard (NTC-1325 of 08-20-2008) for salchichón. It is concluded that pea fiber and cassava starch favor salchichón microbiota, making them primary ingredients for fermented salchichón formulation when developing new products at the industrial level.

Resumen: Se ha demostrado que la variabilidad de la relación marginal capital producto es la que determina la tasa de crecimiento de las economías según el modelo de Harrod, por ello, es importante predecir su comportamiento. Este trabajo desarrolla una metodología basada en la caminata al azar probabilista para predecir la relación marginal capital producto anual de Colombia para el 2017 con base en la información de la base de datos Penn World Table desde 1993 hasta 2016. Se encontró que esta variable posee órdenes matemáticos subyacentes, lo que permite su predicción con una precisión del 97,69%.

Abstract: It has been shown that the variability of the marginal capital product ratio is what determines the growth rate of economies according to Harrod’s model; therefore, it is important to predict its behavior. This paper develops a methodology based on probabilistic random walk to predict the annual marginal capital product ratio of Colombia for the year 2017 based on information from the Penn World Table database from 1993 to 2016. It was found that this variable has underlying mathematical orders, which allows its prediction with an accuracy of 97.69%.

Resumen Contexto: Los cirujanos de intervenciones mínimamente invasivas requieren ampliar la información para realizar las rutas de intervención, este artículo describe un prototipo de realidad mixta de carácter educativo o pre quirúrgico que hace uso del Casco Metavision Meta II. Se crearon objetos 3D de estructuras morfológicas para neurocirugía y laparoscopia a partir de imágenes obtenidas de resonancia magnética MRI y TAC de un paciente real, con el fin de simular el acceso al cerebro y hacer reconocimiento del área abdominal. Métodos: Este prototipo tiene un enfoque educativo cuyo objetivo es incentivar el reconocimiento de esquemas morfológicos de órganos, para lo cual se diseñaron tres pruebas. Estas pruebas consistieron en la búsqueda de tumores a través de la navegación y la interacción con un objeto exhibido en el casco de realidad mixta Meta 2. Para el área neurológica se dedicaron dos de las tres pruebas, en las dos primeras pruebas se midió el tiempo de búsqueda con cinco tumores, y para el área abdominal se realizó también una prueba para la búsqueda de dos tumores, diseñándose diversas interacciones en el recorrido espacial del objeto 3D generado, usando pantallas con despliegues de los cortes tomados de imágenes de tomografía computarizada. Posterior al desarrollo de las tres pruebas se realizó un proceso de medición de inmersión a partir del uso de un cuestionario. Resultados: El 100% de los usuarios encontró altamente interesante la aplicación, en tanto que el 90% expresó que intentó fijar su foco de atención en el desarrollo exitoso de la prueba, indicador del nivel de absorción de la aplicación. También el 70% de los usuarios describió su experiencia como de alto nivel de inmersión. Conclusiones: Las pruebas demostraron que el prototipo es usable, absorbente y tiene un nivel de inmersión aceptable.

Abstract Context: This article describes an educational or pre-surgical mixed-reality prototype using the Metavision Meta II headset. 3D objects of morphological structures for neurosurgery and laparoscopy were created from MRI and CT images of a real patient in order to simulate the access to the brain and conduct a reconnaissance of the abdominal area. Method: This prototype has an educational approach whose objective is to encourage the recognition of morphological schemes of organs, for which three tests were designed. These tests consisted of searching for tumors through navigation and interaction with an object displayed in the Meta 2 mixed-reality headset. Two of the three tests were dedicated to the neurological area, in which the search time was measured with five tumors, and a test was conducted for the abdominal area regarding the search of two tumors, designing various interactions in the spatial path of the generated 3D object. An immersion measurement process was conducted which was based on the use of a questionnaire. Results: 100% of users found the application highly interesting, while 90% expressed that they tried to focus their attention on the successful completion of the test, an indicator of the level of absorption of the application. Furthermore, 70% of users described their experience as highly immersive. Conclusions: Tests showed the prototype to be usable, absorbent, and has an acceptable level of immersion.

Abstract Background: Since the beginning of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, patients with chronic kidney disease vulnerable to suffering more severe COVID-19 disease and worse outcomes have been identified Objectives: Our study's aim was to determine the incidence, characteristics, and outcomes of SARS-CoV-2 infection in patients of hemodialysis (HD) units in Mexico and to describe the availability of confirmatory testing Methods: This study was multicentric study of 19 HD units, conducted between March 2020 and March 2021 Results: From a total of 5779 patients, 955 (16.5%) cases of suspicious COVID-19 were detected; a SARS-CoV-2 reverse transcription polymerase chain reaction test was done in only 50.6% of patients. Forty-five percentages were hospitalized and 6% required invasive mechanical ventilation (IMV). There was no significant difference in mortality between confirmed (131/483) and suspicious (124/472) cases (p = 0.74). The percentage of patients in need of hospitalization, IMV, and deceased was greater than in the rest of the study population Conclusions: The study revealed that 49.4% of the cases were not confirmed, a worrisome observation given that this is a highly vulnerable population (higher probability of contagion and worse outcomes), in which 100% of patients should have a confirmatory test

Abstract Background: A high incidence of acute kidney injury (AKI) has been reported in coronavirus disease 2019 (COVID-19) patients in critical care units and those undergoing invasive mechanical ventilation (IMV). The introduction of dexamethasone (DXM) as treatment for severe COVID-19 has improved mortality, but its effects in other organs remain under study. Objective: The objective of this study was to evaluate the association between DXM and AKI in COVID-19. Methods: In this prospective observational cohort study, we evaluated the incidence of AKI in critically ill COVID-19 patients undergoing mechanical ventilation, and the association of DXM treatment with the incidence, severity, and outcomes of AKI. The association between DXM treatment and AKI was evaluated by multivariable logistic regression. The association of the combination of DXM treatment and AKI on mortality was evaluated by Cox-regression analysis. Results: We included 552 patients. AKI was diagnosed in 311 (56%), of which 196 (63%) corresponded to severe (stage 2 or 3) AKI, and 46 (14.8%) received kidney replacement therapy. Two hundred and sixty-seven (48%) patients were treated with DXM. This treatment was associated to lower incidence of AKI (Odds Radio 0.34, 95% Confidence intervals [CI] 0.22-0.52, p < 0.001) after adjusting for age, body mass index, laboratory parameters, SOFA score, and vasopressor use. DXM treatment significantly reduced mortality in patients with severe AKI (HR 0.63, 95%CI 0.41-0.96, p = 0.032). Conclusions: The incidence of AKI is high in COVID-19 patients under IMV. DXM treatment is associated with a lower incidence of AKI and a lower mortality in the group with severe AKI.

Abstract In search of new materials from industrial waste, aiming at cost, efficiency and reduction of environmental liabilities, this study aimed to evaluate the physical, mechanical, acoustic and thermal characteristics of sandwich panels produced with sheets of Schizolobium amazonicum (paricá) and egg carton core made of cardboard, glued with adhesive phenol formaldehyde (FF), urea formaldehyde (UF) and interleaved the sheets glued with both. The panels were evaluated through thermal, acoustic, physical and mechanical tests. The FF and UF adhesives influenced the physical-mechanical properties of the panels. For thermal conductivity and thermal resistance, it was found that all panels met the normative requirements of NBR 15220 (ABNT, 2005) with emphasis on panels produced with FF. Therefore, the use of paricá sheets 32x12x0.2 cm (length, width and thickness, respectively) and egg box as a core with adhesive, proved to be promising for some uses in civil construction, in addition to adding value to the egg crate residues as thermal and acoustic insulators, can minimize the disposal of raw material in the environment.

Resumo Em busca de novos materiais a partir de resíduos industriais, visando ao custo, à eficiência e à redução do passivo ambiental, este trabalho teve como objetivo avaliar as características físicas, mecânicas, acústicas e térmicas de painéis sanduíche produzidos com lâminas de Schizolobium amazonicum (paricá) e núcleo de caixa de ovos feitos de papelão coladas com o adesivo fenol-formaldeído (FF) e com o adesivo ureia-formaldeído (UF), intercalando-se estas com lâminas coladas com ambos (FF+UF). Os painéis foram avaliados por meio de ensaios térmicos, acústicos, físicos e mecânicos. Os adesivos FF e UF influenciaram nas propriedades físico-mecânicas dos painéis. Para a condutividade térmica e resistência térmica, verificou-se que todos os painéis atingiram as exigências normativas da NBR 15220 (ABNT, 2005), com destaque para os painéis produzidos com FF. Sendo assim, a utilização das lâminas de paricá de 32x12x0,2 cm (comprimento, largura e espessura respectivamente) e de caixa de ovo como núcleo com adesivo se mostrou promissora para algumas aplicações na construção civil, além de agregar valor aos resíduos de caixa de ovo como isolantes térmicos e acústicos, por minimizar o descarte de matéria-prima no meio ambiente.

Abstract This study aimed to use the petiole residues of miriti to partially replace pine wood and evaluate the effects of this incorporation on the physical and mechanical properties of the particleboards. Panels were produced with 0, 25, 50, and 75% of miriti in partial replacement of wood and 12% of urea-formaldehyde adhesive. The chemical-physical properties of miriti residues showed potential particleboard production as they were similar to those of pinewood. For the physical properties, the panels were classified as low density. There was an increase in the compression ratio and, consequently, in the hygroscopicity . For the mechanical properties, it was observed that the modulus of elasticity (MOE) and modulus of rupture (MOR) did not show any statistical differences. For perpendicular traction (PT), there was a significant reduction in 50%. Considering a general analysis of the physical and mechanical properties, up to 40% of mirti can be substituted, as in this situation they meet the properties mentioned in CS-236-66, except for PT for commercialization of the panels.

Resumo O objetivo deste trabalho foi utilizar os resíduos do pecíolo do miriti em substituição parcial da madeira de pinus e avaliar os efeitos dessa incorporação nas propriedades físicas e mecânicas dos painéis aglomerados. Os painéis foram produzidos com 0, 25, 50 e 75% de miriti em substituição parcial de madeira e 12% de adesivo uréia-formaldeído. As propriedades físico-químicas dos resíduos de miriti mostraram potencial de produção de aglomerados, uma vez que foram semelhantes às do pinus. Quanto às propriedades físicas, os painéis foram classificados como de baixa densidade. Houve aumento na taxa de compressão e, consequentemente, na higroscopicidade. Para as propriedades mecânicas, observou-se que o módulo de elasticidade (MOE) e o módulo de ruptura (MOR) não houve diferença estatística. Para tração perpendicular (TP) houve redução significativa de 50%. Considerando uma análise geral das propriedades físicas e mecânicas, é possível uma substituição em até 40% de miriti, pois nessa situação atendem as propriedades mencionadas na CS-236-66, com exceção da TP para a comercialização dos painéis.

Summary The objective of the study was to develop a short version of the Positive Affect and Negative Affect Scale (PANAS), based on the original version of 20 items. The sample consisted of 3960 students from a public university in Lima. The results indicate that the validity of the internal structure, through exploratory and confirmatory factor analysis, was defined by 10 items and two dimensions. Positive affects are organized into five items: determined, optimistic, inspired, active, and attentive; while negative affects are in five items: irritable, hostile, angry, guilty, and ashamed. Likewise, it was found for the final short version, standardized coefficients with factorial loads between .48 and .85, as well as the fit indices of the model were in accordance with what was expected. Internal consistency reliability indicates Alpha and Omega coefficients greater than .70 in both factors. It is concluded that the instrument presents evidence of internal structure and the scores are consistent.
