Resumen (Objetivo) El principal objetivo de esta investigación fue evaluar el potencial de ahorro de agua potable, mediante el empleo de la pluvial como una fuente de abastecimiento para usos no potables, en dos barrios con viviendas de interés social del municipio de Viçosa (Minas Gerais, Brasil). (Metodología) Se utilizaron las estadísticas de consumo correspondientes a cada mes del 2020, para cada una de las casas que conforman los complejos habitacionales Benjamín José Cardoso y Sol Nascente, así como se estimó la fracción de agua potable destinada en los hogares para usos no potables. Se analizó la información correspondiente a los registros de lluvias mensuales de los últimos 50 años y se calculó el volumen mensual de agua de lluvia que podría colectarse en cada casa. (Resultados) El volumen promedio mensual de agua pluvial que podría captarse en el área de tejado de cada hogar es 3,39 m3. Durante los meses lluviosos del año, podría almacenarse un porcentaje de agua mayor al destinado para usos no potables; el dimensionamiento de un reservorio de agua de lluvia que supere las necesidades por mes del líquido para dichos propósitos podría viabilizar un excedente de agua colectada que garantice el recurso a lo largo de la temporada seca. (Conclusiones) Ya que el porcentaje promedio de ahorro de agua potable para ambos barrios supera el 53 %, el ahorro de consumo mensual puede contribuir a la reducción en el pago del servicio del agua potable y el consumo del líquido del municipio, principalmente en los meses de sequía.

Resumo (Objetivo) O principal objetivo desta pesquisa foi avaliar o potencial de economia de água potável por meio do uso da água pluvial como fonte de abastecimento para usos não potáveis em dois bairros com habitações de interesse social no município de Viçosa (Minas Gerais-Brasil). (Metodologia) Foram utilizadas estatísticas de consumo de cada mês do ano de 2020 para cada uma das casas que compõem os conjuntos habitacionais Benjamin José Cardoso e Sol Nascente, e foi estimada a fração de água potável utilizada nas residências para usos não potáveis. Foram analisados os registros mensais de dos últimos 50 anos e calculado o volume mensal de águas pluviais que poderia ser coletado de cada residência. (Resultados) O volume médio mensal de águas pluviais que poderia ser coletado da área do telhado de cada residência é de 3,39 m3. Durante os meses chuvosos do ano, poderia ser armazenada uma porcentagem maior de água do que aquela destinada a usos não potáveis; o dimensionamento de um reservatório de águas pluviais que ultrapassem as necessidades mensais do líquido para esses fins poderia viabilizar um excedente de água coletada para garantir o líquido durante a estação seca. (Conclusões) Como a porcentagem média de economia de água potável para ambos os bairros é superior a 53%, a economia no consumo mensal pode contribuir para a redução do pagamento do serviço de água potável do município e do consumo do líquido, principalmente nos meses de seca.

Abstract (Objective) The main objective of this research was to evaluate the potential for saving drinking water by using rainwater as a source of supply for non-potable purposes in two neighborhoods with social housing in the municipality of Viçosa, Minas Gerais, Brazil. (Methodology) The consumption statistics for each month of 2020 were used for each of the homes comprising the Benjamin José Cardoso and Sol Nascente Housing Complexes, and the fraction of drinking water that is destined in homes for nonpotable purposes was estimated. The information corresponding to the monthly rainfall records of the last 50 years was analyzed and the monthly volume of rainwater that could be harvested in each house was calculated. (Results) The average monthly volume of rainwater that could be captured through the roof area of each dwelling is 3.39 m3. During the rainy months of the year, it would be feasible to save a higher percentage of water than that allocated for non-potable purposes. Sizing a rainwater reservoir that exceeds the monthly needs for non-potable purposes would allow the surplus of collected water to supply the liquid during the dry season. (Conclusions) Since the average percentage of savings in drinking water for both neighborhoods exceeded 53%, the saving of the monthly consumption can contribute to the reduction of payments for the drinking water service and the consumption of the liquid in the municipality, particularly during drought months.

ABSTRACT Rice (Oryza sativa) is among the most important crops worldwide; however, rice crops demand high water consumption. Future projections indicate reduced water availability and severe drought events, which may affect rice crops as the cereal is highly sensitive to drought stress. Thus, cultivars with lower water demand for irrigation or drought escape capacities are among the strategies to address this issue. This study aimed to assess five mutant rice genotypes in terms of growth cycle length, other agronomic interest traits, and drought response in the reproductive stage. The mutant genotypes evaluated showed a shortening of the growth cycle compared to the original cultivar, BRS Pampeira, representing a drought escape strategy. In addition, mutations did not negatively affect plant height and crop yield. However, similar to the original cultivar, mutants are not tolerant to water deficit in the reproductive stage. The genotypes evaluated have potential to be released as early cycle cultivars, which can reduce water demand during the harvest season while presenting a drought escape strategy. Oryza sativa worldwide however consumption events stress Thus issue length traits stage cultivar Pampeira strategy addition yield However

ABSTRACT In Paraguay, one of the most traditional and massively cultivated crops by producers is the corn, obtaining high yields depends on management practices such as planting time and fertilization management. This research was carried out with the objective of evaluating the effect of fertilization with different nitrogen source, applied 2 times at the late planting season. The following nitrogen fertilizers used were: Urea 30 kg ha-1, Liquid nitrogen (N) 30 kg ha-1, Urea 60 kg ha-1, liquid N 60 kg ha-1, Urea 90 kg ha-1, liquid N 90 kg ha-1 applied in 2 application moments (vegetative state V3 and V6). The experimental design was a factorial arrangement in complete random blocks, considering two factors: 2 sources of N and 3 levels of each source. The weight of 1000 grains, grain yield and agronomic nitrogen efficiency (EAN) were evaluated. The weight of 1000 grains was shown to be influenced both by the application times, as well as by the sources of N and the interaction between both, the yield did not have an effect on the interaction of the factors, while these factors individually had an effect on this variable, the EAN had no effect at the time of application. Liquid N 30 kg ha-1 applied in phenological stage V6 could be recommended as a fertilization practice for corn planted in the late season in southern Paraguay.

RESUMEN En el Paraguay unos de los cultivos más tradicionales y masivamente cultivado por los productores es el maíz, la obtención de altos rendimientos depende de prácticas de manejo como la época de siembra y el manejo de la fertilización, la investigación se realizó con el objetivo de evaluar el efecto de la fertilización con distintas fuentes de nitrógeno aplicados en dos momentos en época tardía de siembra. Se utilizaron como fertilizantes nitrogenados: Urea 30 kg ha-1 Nitrógeno (N) liquido 30 kg ha-1, Urea 60 kg ha-1, N liquido 60 kg ha-1, Urea 90 kg ha-1, N liquido 90 kg ha-1 y dos momentos de aplicación (estado vegetativo V3 y V6). El diseño experimental fue arreglo factorial dispuesto en bloques completos al azar, se consideraron dos factores: dos fuentes de N y tres dosis de cada fuente. Se evaluaron el peso de 1000 granos, rendimiento de granos y la eficiencia agronómica del nitrógeno (EAN). El peso de 1000 granos mostró ser influenciado tanto por los momentos de aplicación, así como por las fuentes de N y la interacción entre ambos, el rendimiento no presentó efecto en la interacción de los factores, mientras que estos factores individualmente presentaron efecto sobre esta variable, la EAN no presentó efecto ante los momentos de aplicación. N liquido 30 kg ha-1 aplicado en estado fenológico V6 se podría recomendar como practica de fertilización del maíz sembrado en época tardía en el sur de Paraguay.

Abstract: Introduction: Atrial fibrillation (AF) is the most common cardiac arrhythmia in patients with heart failure (HF), regardless of ejection fraction, leading to a greater risk of thromboembolic complications. Anticoagulation is one of the fundamental pillars in the treatment of AF, and prior to this, it is recommended to evaluate the embolic risk using the CHA2DS2-VASc score and the bleeding risk with the HAS-BLED score. There are two pharmacological groups of oral anticoagulants (OACs), vitamin K antagonists (VKAs), and direct oral anticoagulants (DOACs). Both groups have advantages and disadvantages in their use. VKAs require frequent monitoring to achieve INR levels within range, a greater number of drug and dietary interactions, leading to lower adherence, satisfaction, and quality of life. Likewise, scientific evidence supports the non-inferiority of DOACs versus VKAs, being recommended in recent clinical practice guidelines for the prevention of thrombotic events in all patients with AF except in cases where moderate to severe mitral stenosis or mechanical valve replacement coexist. To date, there are no published studies that assess adherence and impact on quality of life with the use of DOACs in HF with AF. Therefore, the objective of this research is to observe changes in adherence and quality of life of patients who were switched from VKA to DOAC, describing the occurrence of thrombotic or hemorrhagic events. Methodology: Quasi-experimental, prospective, longitudinal study. All patients over 18 years of age with AF without mechanical valve prosthesis or moderate/severe mitral stenosis, anticoagulated with warfarin with therapeutic range time (TTR) ≤65% and SAMe-T2R ≥2 were included. The Morisky questionnaire was administered to evaluate adherence, and the Anti-Clot Treatment Scale was used to evaluate satisfaction and quality of life. Thrombotic and hemorrhagic risk was evaluated by CHA2DS2-VASc and HAS-BLED. The questionnaires were applied using warfarin and the same questionnaires were repeated after replacing with DOAC for convenience, specifically apixaban. Statistical analysis was performed using the Kolmogorov-Smirnov test, Cochrane Q test, ANOVA, and STATAv.15.0. Results: 43 patients, 31 of whom were male, 100% had CHA2DS2-VASC >2, 37% had HAS-BLED >3, and 62.8% had SAMe-TT2R2 >2. There was a statistically significant difference (p<0.001) in relation to the use of apixaban in quality of life, disease burden, and positive impact. No thrombotic or hemorrhagic events were observed with the use of apixaban. Conclusions: A statistically significant difference was observed in adherence, satisfaction, and quality of life with the use of apixaban, without thrombotic or hemorrhagic events.

Resumo: Introdução: A fibrilação atrial (FA) é a arritmia cardíaca mais comum em pacientes com insuficiência cardíaca (IC), independentemente da fração de ejeção, o que leva a um maior risco de complicações tromboembólicas. A anticoagulação é um dos pilares fundamentais no tratamento da FA e, antes disso, é recomendado avaliar o risco embólico usando o escore CHA2DS2-VASc e o risco de sangramento com o escore HAS-BLED. Existem dois grupos farmacológicos de anticoagulantes orais (AOs): os antagonistas da vitamina K (AVKs) e os anticoagulantes orais diretos (DOACs). Ambos os grupos têm vantagens e desvantagens em seu uso. Os AVKs exigem monitoramento frequente para alcançar níveis de RNI dentro da faixa, um maior número de interações medicamentosas e alimentares, levando a menor adesão, satisfação e qualidade de vida. Da mesma forma, a evidência científica suporta a não inferioridade dos DOACs em relação aos AVKs, sendo recomendados nas diretrizes recentes de prática clínica para a prevenção de eventos trombóticos em todos os pacientes com FA, exceto nos casos em que coexistem estenose mitral moderada a grave ou substituição valvar mecânica. Até o momento, não há estudos publicados que avaliem a aderência e o impacto na qualidade de vida com o uso de DOACs em IC com FA. Portanto, o objetivo desta pesquisa é observar mudanças na adesão e qualidade de vida de pacientes que mudaram de AVK para DOAC, descrevendo a ocorrência de eventos trombóticos ou hemorrágicos. Metodologia: Estudo quase-experimental, prospectivo e longitudinal. Foram incluídos todos os pacientes com mais de 18 anos de idade com FA sem prótese valvar mecânica ou estenose mitral moderada/grave, anticoagulados com varfarina com tempo de alcance terapêutico (TTR) ≤65% e SAMe-T2R ≥2. O questionário Morisky foi administrado para avaliar a adesão, e a Escala de Tratamento Anticoagulante foi usada para avaliar a satisfação e qualidade de vida. O risco trombótico e hemorrágico foi avaliado pelo escore CHA2DS2-VASc e HAS-BLED. Os questionários foram aplicados usando varfarina e os mesmos questionários foram repetidos após a substituição por DOAC por conveniência, especificamente apixabana. A análise estatística foi realizada usando o teste de Kolmogorov-Smirnov, teste Q de Cochrane, ANOVA e STATAv.15.0. Resultados: Foram incluídos 43 pacientes, sendo 31 do sexo masculino. Todos os pacientes apresentavam CHA2DS2-VASC >2, 37% tinham HAS-BLED >3 e 62,8% tinham SAMe-TT2R2 >2. Foi observada uma diferença estatisticamente significativa (p<0,001) no que diz respeito ao uso de apixabana na qualidade de vida, carga da doença e impacto positivo. Não foram observados eventos tromboembólicos ou hemorrágicos com o uso de apixabana. Conclusões: Foi observada uma diferença estatisticamente significativa na adesão, satisfação e qualidade de vida em relação ao uso de apixabana, sem eventos tromboembólicos ou hemorrágicos.

Resumen: Objetivo: Caracterizar el comportamiento de COVID-19 en niños chilenos hospitalizados en unidades de paciente crítico pediátrico (UPCP) y evaluar factores de riesgo para COVID-19 severo. Pacientes y Método: Estudio multicéntrico cohorte prospectivo, pacientes 0-18 años con SARS-CoV-2 confirmado hospitalizados en UPCP. Se registraron variables clínicas, laboratorio, imagenológicas y terapéuticas. Se comparó “COVID-19 leve/moderado” versus “COVID-19 severo” utilizando mediana con rango intercuartil (RIC), test U Mann-Whitney, Test Fisher de dos colas y análisis multivariado binario forward para ajuste de variables para “COVID-19 severo”. Significativo p < 0,05. Resultados: 219 pacientes, 55,3% hombres, mediana edad 86 meses (RIC: 13,5-156). Comorbilidades principales: obesidad, enfermedades respiratorias. Mortalidad global: 3,6%. “COVID-19 severo” (26,5%) mostró más leucopenia, linfopenia, más inflamación y alteración de órganos (p < 0,05). También desarrolló más Sepsis/shock, SDRA y disfunción de órganos, requirió más terapia hemodinámica, antiinflamatoria, anticoagulación, antibioterapia, con mayor estadía en UPCP/hospitalaria (p < 0,05) y mortalidad de 13,8%. Factores de riesgo asociados a “COVID-19 severo”: shock al ingreso (aOR 28,44 [IC95%: 10,45-77,4]), obesidad (aOR 3,55 [IC95%: 1,3-9,6]), condensación (aOR 3,1 [IC95%: 1,1-8,7]), atelectasia (aOR: 8.7 [IC95%: 1,17-64,3]), corticoides dosis de estrés (aOR 7,7 [IC95%: 1,9-30,6]), antibioterapia precoz (aOR: 12,02 [IC95%: 1,11-130,02]), inmunodeficiencia adquirida/ congénita (aOR: 19,2 [IC95%: 1,19-321]) y patología oncológica (aOR: 10,7 [IC95%: 2,14-47,8]). Conclusión: En esta cohorte pediátrica chilena, el perfil de paciente que ingresó a UPCP fue de sexo masculino en edad escolar con comorbilidad asociada. Factores de riesgo asociados a COVID-19 severo fueron: presencia de comorbilidades (inmunodeficiencia adquirida/congénita, patología oncológica y obesidad), shock al ingreso y condensaciones en las imágenes radiológicas.

Abstract: Objectives: To characterize the COVID-19 disease profile in Chilean children hospitalized in pediatric intensive care units (PICU) and to evaluate risk factors associated with severe COVID-19. Patients and Method: A multicenter prospective cohort study with patients 0-18 years of age with confirmed SARS-CoV-2 hospitalized in PICU. Clinical, laboratory, imaging, and therapeutic variables were recorded. We compared ”mild/moderate COVID-19” with ’’severe COVID-19” using median with interquartile range (IQR), Mann-Whitney U test, two-tailed Fisher’s test, and forward binary multivariate analysis to adjust variables for “severe COVID-19”. A p < 0.05 was considered significant. Results: From 16 PICUs, 219 patients were recruited, 55.3% were male, with a median age of 86 months (IQR: 13.5-156). The most frequent comorbidities were obesity and respiratory diseases. Overall mortality was 3.6%. “Severe COVID-19” (26.5%) showed more leukopenia, lymphopenia, increased inflammatory parameters, and altered organ function (p < 0.05). It also developed more sepsis/shock, ARDS, and organ dysfunction, requiring more hemodynamic, anti-inflammatory, anticoagulation, and antibiotic therapy, with a longer stay in the PICU/hospital (p < 0.05), and 13.8% of mortality. Risk factors associated with “severe COVID-19” were shock on admission to the PICU [aOR 28.44 (95%CI 10.45-77.4)], obesity [aOR 3.55 (95%CI 1.3-9.6)], consolidation [aOR 3.1 (95%CI 1.1 -8.7)], atelectasis [aOR: 8.7 (95%CI 1.17-64.3)], stress dose of corticosteroids [aOR 7.7 (95%CI 1.9-30.6)], early antibiotic therapy [aOR: 12.02 (95%CI 1.11-130.02)], acquired/congenital immunodeficiency [aOR: 19.2 (95%CI: 1.19-321)], and oncological pathology [aOR 10.7 (95%CI 2.14-47.8)]. Conclusion: In this Chilean pediatric cohort, most patients with COVID-19 admitted to de PICU were male, of school age, with associated comorbidity. Risk factors for developing severe COVID-19 were the presence of comorbidities such as acquired/congenital immunodeficiency, oncological pathology, and obesity, in addition to shock on admission and consolidations on X-rays.

Abstract Objective: To evaluate clinical characteristics, impact on quality of life and factors associated with vertigo in pregnant women hospitalized in a highly complex institution. Method: A cross-sectional study was conducted in 2021-2022. One focused survey including Dizziness Handicap Inventory (DHI) was performed. The statistical analysis was performed using a generalized lineal regression. Results: 103 patients were included, 19.4% indicated vertigo mostly during the second semester (60%). A median of 3.5 episodes was obtained (RIC: 1.5-7.5). Positional and episodic vertigos (40%) associated with unsteadiness (60%), headache (60%), photopsia (55%) and tinnitus (45%) were described. DHI in pregnant females with vertigo compared to those without vertigo, presented higher rates of moderate to severe disability in the emotional (30 vs. 2.4%: p = 0.001), functional (40 vs. 2.4%; p < 0.001) and physical (55 vs. 2.4%; p < 0.001) dimensions. Hospitalizations during the pregnancy (RP: 4.02; 95%CI: 1.64-9.85; p = 0.002) and previous episodes before pregnancy (RP: 2.37; 95%CI: 1.15-4.88; p = 0.019) were identified as associated factors with current vertigo episodes. Conclusions: The high frequency of vertigo in pregnant women suggests the importance of studying this condition during pregnancy, to achieve comprehensive management and generate effective prevention and control actions.

Resumen Objetivo: Evaluar las características clínicas, el impacto en la calidad de vida y los factores asociados con vértigo en gestantes hospitalizadas en una institución de alta complejidad. Método: Estudio transversal. Se realizó una encuesta dirigida a la presencia de vértigo y sus características clínicas en 2020-2021. La calidad de vida se evaluó con el cuestionario Dizziness Handicap Inventory (DHI). El análisis estadístico incluyó un modelo lineal generalizado. Resultados: De 103 mujeres, el 19,4% indicaron vértigo principalmente en el segundo trimestre de gestación (60%), con una mediana de 3,5 (rango intercuartil: 1,5-7,5) episodios. Fueron referidos vértigos episódicos asociados con cambios posicionales (40%), acompañados de inestabilidad (60%), cefalea (60%), fotopsias (55%) y tinnitus (45%). Las mujeres con vértigo presentaron mayor frecuencia de discapacidad moderada a grave en las dimensiones del DHI emocional (30 vs. 2,4%; p = 0,001), funcional (40 vs. 2,4%; p < 0,001) y física (55 vs. 2,4%; p < 0,001) en comparación con las mujeres sin la patología. La hospitalización durante el embarazo Razón de proporción (RP): 4,02; intervalo de confianza del 95% [IC95%]: 1,64-9,85; p = 0,002) y la presencia de vértigo pregestacional (RP: 2,37; IC95%: 1,15-4,88; p = 0,019) se identificaron como factores asociados. Conclusiones: La alta frecuencia de vértigo en las gestantes sugiere la importancia de estudiar esta condición durante el embarazo, para lograr un manejo integral y generar acciones de prevención y control efectivas.

ABSTRACT Zinc (Zn) is an essential nutrient for plants, and there is limited information on its availability in Paraguayan soils. The objective of the research was to evaluate and classify the availability of Zn in soils of the Eastern region of Paraguay. For this, a database was generated with the results of soil analyses from the FCA-UNA, CIHB-IPTA and FUCAI-UCA laboratories. The concentration of available Zn in soils was classified as "high" (>1.2 mg kg-1); “medium” (0.5 - 1.2 mg kg-1) and “low” (<0.5 mg kg-1), generating a Zn availability map at the district level. The availability of Zn was evaluated at the district and departmental levels, as well as with descriptive statistics parameters. Considering the average Zn levels at the district level, of the 234 districts that make up the Eastern region of Paraguay, 74% of the districts (174 districts) presented a "high" level, 6% a "medium" level (15 districts) and 3% “low” level of Zn (6 districts). Considering the total number of soil samples analyzed (11,395 samples), 79% (9,038 samples) presented "high" levels of Zn, 12% (1,316 samples) presented "medium" levels of Zn, and only 9% (1,041 samples) presented “low” levels of Zn. The national average, considering the 11,395 soil samples, was 6.5 mg kg-1 of Zn, therefore, in 79% of the soils analyzed in the Eastern region there are Zn levels above the critical level of Zn for agricultural activities, forage and forestry production.

RESUMEN El Zinc (Zn) es un nutriente esencial para las plantas, existe limitada información de su disponibilidad en los suelos de Paraguay. El objetivo de la investigación consistió en evaluar y clasificar la disponibilidad de Zn en suelos de la región Oriental del Paraguay. Para ello fue generada una base de datos con los resultados de análisis de suelo de los laboratorios de la FCA-UNA, CIHB-IPTA y FUCAI-UCA. Se clasificó la concentración de Zn disponible de los suelos en nivel “alto” (>1,2 mg kg-1); “medio” (0,5 - 1,2 mg kg-1) y “bajo” (<0,5 mg kg-1), generándose un mapa de disponibilidad de Zn a nivel distrital. Se evaluó la disponibilidad de Zn a nivel distrital, departamental, así como, con parámetros de estadística descriptiva. Considerando la media de los niveles de Zn a nivel de distrito, de los 234 distritos que conforman la región Oriental del Paraguay, en el 74% de los distritos (174 distritos) presentaron nivel “alto”, 6% nivel “medio” (15 distritos) y el 3% nivel “bajo” de Zn (6 distritos). Considerando el número total de muestras de suelo analizadas (11.395 muestras), el 79% (9.038 muestras) presentaron niveles “alto” de Zn, el 12% (1.316 muestras) presentaron niveles “medio” de Zn, y solo el 9% (1.041 muestras) presentaron niveles “bajo” de Zn. La media nacional considerando las 11.395 muestras de suelo fue de 6,5 mg kg-1 de Zn, por lo tanto, en 79% de los suelos analizados de la región Oriental hay niveles de Zn superior al nivel crítico de Zn para las actividades agrícolas, de forrajes y forestales de producción.

Introducción: CS (congenital syphilis) is a serious disorder that, if it does not cause death at an early age, can cause permanent disorders. This can be almost completely prevented, as long as the mother receives adequate and timely treatment. Objective: To establish the structural and intermediate determinants that best explain the outcome of congenital syphilis. Methodology: Descriptive observational study with analytical intention and focus on social determinants of health, carried out in a cohort of pregnant women confirmed with gestational syphilis, active members of an insured person in Valle del Cauca between 2015 and 2020, exploratory analysis was carried out by absolute frequencies. and related bivariate analyzes with contingency tables using the chi square test and multivariate logistic regression analysis. Results: A higher volume of cases of gestational syphilis was found in women living in urban areas, in the subsidized regime, in socioeconomic status one or two, and in vulnerable population groups such as displaced persons, in prison, and residents of the municipalities of Cali and the district of Bonaventure. Conclusions: The structural and intermediate determinants that increase the probability of congenital syphilis outcome were pregnant women in the subsidized regime, rural area, indigenous and ROM (gypsy) ethnic groups, socioeconomic stratum 2, with late diagnosis, absent prenatal check-ups, without screening tests, without their own treatment or contacts, residents in municipalities far from the capital and with a higher infant mortality rate.

Introducción: La SC (sífilis congénita) es un trastorno grave que, si no provoca la muerte a edad temprana, puede causar trastornos permanentes. Esto puede prevenirse casi por completo, siempre y cuando la madre reciba un tratamiento adecuado y oportuno. Objetivo: Establecer los determinantes estructurales e intermedios que mejor explican el desenlace de sífilis congénita. Metodología:Estudio observacional descriptivo con intención analítica y enfoque en determinantes sociales de la salud, realizado en una cohorte de gestantes confirmadas con sífilis gestacional, afiliadas activas a una asegurada en el Valle del Cauca entre 2015 y 2020, se realizó análisis exploratorios por frecuencias absolutas y relacionadas , análisis bivariados con tablas de contingencia utilizando la prueba de chi cuadrado y análisis multivariado de regresión logística. Results: Se encontró mayor volumen de casos de SG en mujeres residentes de la zona urbana, del régimen subsidiado, de estrato socioeconómico uno o dos y de grupos poblacionales vulnerables como desplazadas, en condición carcelaria y residente en los municipios de Cali y el distrito de Buenaventura. Conclusiones:los determinantes estructurales e intermedios que incrementaron la probabilidad de desenlace de SC fueron las gestantes del régimen subsidiado, área rural, de etnias indígenas y ROM (gitanos), de estrato socioeconómico 2, con diagnóstico tardío, que no asistieron a los controles prenatales, sin pruebas de tamizaje, sin tratamiento propio ni de contactos, residentes en municipios alejados de la capital y con mayor tasa de mortalidad infantil.

In March 2020, the closure of schools in most countries and the implementation of virtual education were ordered as a control measure to slow the spread of SARS-CoV-2. This, along with social distancing, represented a threat to the mental health of school children. In this context, access to information technologies was a determining factor in countering social isolation and allowing the continuity of the school’s role in this population. In this sense, several studies reported that the suspension of in-person classes and the use of virtual education, adopted because of the pandemic, had both positive and negative effects on the mental health of the pediatric population; conditioned by individual, family, and socioeconomic factors. Thus, in terms of development and mental health, the reopening of educational institutions after a prolonged period of mobility restriction and social distancing constituted both an opportunity and a challenge for the pediatric population and the family. The objective of this article is to reflect on the differential impact that school closures and the implementation of virtual education during the COVID-19 pandemic had on the development and mental health of the school-aged population, and on the potential effects of returning to in-person education. It is hoped that this reflection will be useful in guiding the implementation of educational and child mental health care actions in future pandemics.

Abstract This study aimed to carry out a bibliometric analysis of the production on International Entrepreneurship IE based on perspectives of the thematic structure of the field using thematic mapping techniques to model the knowledge produced in it. Data from the scientific production on the subject were collected from Scopus and Web of Science databases. Three thematic maps representing the periods of 1995-2004, 2005-2014 and 2015-2022 were yielded in the study. The discussion of results concludes that IE is a research area that has grown significantly since the second period, showing a considerable increase in publications from 127 in the first period to 1,042 in the second. This increase remained constant reaching 1,934 in the third and final period. The themes that stood out the most and were most representative in the field of IE were: performance of companies in IE, innovation, knowledge, entrepreneurial companies, entrepreneurial orientation, management, strategy, model and export behavior. A conceptual variation of the themes was also observed with the performance theme standing out, maintaining a high representativeness in the three periods analyzed with displacements between the basic themes – transversal – and the driving themes. Another highlight was the capabilities theme, which, over time, resulted in the dynamic capabilities theme. As emerging themes, performance, entrepreneurial orientation, entrepreneurship, impact and management appear. Based on the results and conclusions of this study, a research agenda is proposed.

Resumo O objetivo deste estudo foi realizar uma análise bibliométrica da produção sobre Empreendedorismo Internacional (EI). Para tanto, a partir de perspectivas da estrutura temática do campo, foi utilizada a técnica de mapeamento temático para modelar o conhecimento produzido no campo de estudos de EI. Os dados da produção científica sobre o tema foram coletados a partir de consulta nas bases da Scopus e da Web of Science. Emergiram do estudo três mapas temáticos representando os períodos 1995-2004, 2005- 2014 e 2015-2022. O estudo conclui que o EI é uma área de pesquisa que cresceu bastante a partir do segundo período, apresentando um aumento explosivo nas publicações, passando de 127 no primeiro período para 1.042 no segundo. Esse aumento se manteve constante chegando a 1.934 no terceiro e último período. Os temas que mais se destacam e são mais representativos na pesquisa sobre EI foram: desempenho das empresas no EI, inovação, conhecimento, empresas empreendedoras, orientação empreendedora, gestão, estratégia, modelo e comportamento exportador .

Introduction: The COVID-19 pandemic quickly became a global public health priority between 2020 and 2022, a time when biologicals were developed and approved in record time. The purpose of this research is to measure the impact of vaccination. in fatality due to COVID 19 in an insurer in the Colombian southwest. Methodology: A cross-sectional observational study was carried out with analytical intention, in active affiliates of the insurer, detected and confirmed with PCR or antigen tests, to calculate the lethality, the quotient of deaths and number of confirmed cases in the study period, the sources for morbidity and mortality they were SIVIGILA, SISMUESTRAS, SEGCOVID, RIPS and RUAF; while the source of the vaccinated population was PAIWEB and a web 2.0 application, Results: From the first case registered on March 17, 2020 to August 30, 2022, the insurer registered 97,274 cases of COVID 19, and 3,619 deaths, resulting in a fatality of 3.7%, the majority was confirmed by antigen tests and among the cases in the post-vaccination period the effective coverage of dose 1 was around 30%, in all doses the most frequent biologics were Sinovac and Pfizer. Conclusions: lethality was significantly associated with exposure to vaccination, being lower in the population immunized with at least one dose, in all age groups (p value 0.0001 lt; 0.05).

Introducción: La pandemia por COVID-19, rápidamente se convirtió en una prioridad en salud pública a nivel mundial entre 2020 y 2022, tiempo donde se desarrollaron y aprobaron en tiempo récord biológicos, el objeto de la presente investigación es medir el impacto de la vacunación en la letalidad por COVID 19 en una aseguradora del suroccidente colombiano. Metodología: Se realizó un estudio observacional transversal con intención analítica, en afiliados activos a la aseguradora, detectados y confirmados con pruebas PCR o antígeno, para calcular la letalidad se realizó el cociente defunciones y número de casos confirmados en el periodo de estudio, las fuentes para la morbimortalidad fueron SIVIGILA, SISMUESTRAS, SEGCOVID, RIPS y RUAF; mientras la fuente de la población vacunada fue PAIWEB y un aplicativo web 2.0, Resultados: Desde el primer caso registrado el 17 de marzo de 2020 al 30 de agosto de 2022 la aseguradora registró 97.274 casos de COVID 19, y 3.619 fallecidos resultando una letalidad de 3,7%, la mayoría se confirmó por pruebas de antígeno y entre los casos en el periodo posvacunación la cobertura efectiva de dosis 1 fue alrededor del 30%, en todas las dosis los biológicos más frecuentes fueron Sinovac y Pfizer. Conclusiones: la letalidad se asoció significativamente con la exposición a la vacunación siendo inferior en población inmunizada con al menos una dosis, en todos los grupos de edad (p valor 0,0001 lt; 0,05)

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.
