ABSTRACT Isolated palsy of the inferior oblique muscle is the least frequent of all palsies affecting the extraocular muscles. We present a six-year-old female patient with a medical history who was brought by her mother to the pediatric ophthalmology and strabismus clinic because she presented an ocular deviation since the first months of her life. A Brown's syndrome of the left eye or left inferior oblique muscle palsy was proposed as possible diagnoses, the second diagnosis was confirmed with the forced duction test. There are several surgical options for these patients. The objective was to determine if surgical alignment in the primary gaze position is achieved with the proposed surgical intervention of right superior rectus recession 5 mm. The patient is aligned in the primary gaze position, without limitation of the versions and without torticollis.

RESUMEN La parálisis aislada del músculo oblicuo inferior constituye la parálisis menos frecuente de todas las que afectan a los músculos extraoculares. Se realiza la presentación de una paciente de seis años de edad con antecedentes de salud que fue traída por su madre a la consulta de oftalmología pediátrica y estrabismo por presentar una desviación ocular desde los primeros meses de nacida. Se planteó como posibles diagnósticos un síndrome de Brown del ojo izquierdo o una parálisis del músculo oblicuo inferior izquierdo, se confirmó el segundo diagnóstico con el test de ducción forzada. Existen varias opciones quirúrgicas para estos pacientes. El objetivo fue determinar si se logra el alineamiento quirúrgico en la posición primaria de mirada con la intervención quirúrgica propuesta de recesión del recto superior derecho 5 mm. La paciente se encuentra alineada en posición primaria de mirada, sin limitación de las versiones y sin tortícoli.

Abstract: En | Text: En | PDF: En

Sustainable and environmentally friendly methods for nanomaterials synthesis have been emerging recently. The use of extracts of polyphenol-rich plants with high reducing and chelating power is advantageous because the polyphenol can protect the nanomaterial from agglomeration and deactivation. Green nanomaterials have been applied in several areas, including remediation of toxic organic pollutants from contaminated effluents. Herein, we describe the preparation of green iron oxide nanoparticles (IONPs) with extracts of the plant Camellia sinensis as black tea for dye removal application. The as-prepared IONPs were composed of amorphous FeOOH and FeII/III-polyphenol complexes. To obtain crystalline and pure iron-based nanomaterials, the amorphous precursor was annealed at 900 ºC. Samples of black tea from different regions were used to verify the reproducibility of the iron phases formed. The same iron phases were obtained for all black tea samples, α-Fe2O3 (hematite), FePO4, and Fe3PO7, but in different proportions. The materials were applied as heterogeneous-Fenton catalysts for the removal of the dye methyl orange. The amorphous as-prepared IONPs were more active than the respective annealed IONPs due to the proton release from the polyphenol into the reaction medium, setting the pH to around 3, which is the optimum pH for the Fenton system.

RESUMO O objetivo deste artigo é apresentar o caso de uma égua crioula colombiana de 15 anos com histórico de abortos e não obtenção de embrião, onde foi realizada avaliação do sistema genital externo e interno, ultrassonografia, citologia, cultura e biópsia endometrial realizados como métodos diagnósticos.; que relataram endometrite crônica de classificação II B, associada a edema tipo 4, estabelecendo prognóstico reservado para reprodução, após constatação de endometrite fúngica. O tratamento consistiu no uso de complexos vitaminicos, medicamentos biorreguladores, antifúngicos e antibióticos, nutracêuticos, minerais e lavagens intrauterinas. Após a medicação e três intervalos ovulatórios consecutivos, quatro embriões foram recuperados e transferidos com sucesso, dos quais três chegaram a termo, demonstrando assim a recuperação da função endometrial, graças à identificação dos microorganismos envolvidos e ao estabelecimento de terapia adequada. A endometrite é definida como a inflamação do endométrio, sendo considerada uma das principais causas de sub e infertilidade na égua, que geram perdas econômicas significativas, com incidência de 10 a 15 %. Existem diferentes etiologias, destacando-se a má conformação do perineo, útero abdominal, perda da atividade miometrial, número de montas, fatores moleculares e genéticos, além da presença de bactérias e fungos.

Abstract The high nutritional value of brassicas can increase productivity in traditional forage production systems. The objective of the study was to compare the nutritional value and yield of dry matter (DM) and nutrients between forage brassicas and traditional autumn-winter species. The forage brassicas were Winfred, Hunter and Graza radish and the traditional forages were oats, triticale, barley, wheat and berseem clover. The study was conducted in Matamoros, Coahuila, Mexico in the 2018-2019 cycle, under a randomized complete block experimental design with four repetitions. The regrowth capacity, the nutritional composition of the forage and the yields of DM and nutrients were determined. All species showed regrowth capacity, with three cuts in berseem clover in 154 d, and with two cuts in brassicas (150-154 d) and cereals (133-144 d). The brassicas had nutritional composition similar to that of berseem clover and better than that of cereals, mainly due to their higher content of net energy of lactation (NEL; 6.57 to 7.32 MJ kg-1 DM). The DM yields of the brassicas were similar to those observed in traditional forages; however, due to their high nutritional composition, the brassicas were equal to or superior in production of crude protein (CP) (1,608 to 2,986 kg ha-1) and NEL (62,819 to 84,044 MJ ha-1) to traditional forages. In general, forage brassicas can increase nutrient yield with respect to cereals and berseem clover, especially in the production of NEL (27.5 to 47.3 %).

Resumen El alto valor nutritivo de las brásicas puede incrementar la productividad en los sistemas de producción de forrajes tradicionales. El objetivo del estudio fue comparar el valor nutricional y el rendimiento de materia seca (MS) y nutrientes entre brásicas forrajeras y especies tradicionales de otoño-invierno. Las brásicas forrajeras fueron Winfred, Hunter y rábano Graza y los forrajes tradicionales fueron avena, triticale, cebada, trigo y el trébol Alejandrino. El estudio se realizó en Matamoros, Coahuila, México en el ciclo 2018-2019, bajo un diseño experimental de bloques completos al azar con cuatro repeticiones. Se determinó la capacidad de rebrote, la composición nutricional del forraje y los rendimientos de MS y nutrientes. Todas las especies presentaron capacidad de rebrote, con tres cortes en trébol Alejandrino en 154 días, y con dos cortes en brásicas (150-154 días) y cereales (133-144 días). Las brásicas presentaron similar composición nutricional al trébol Alejandrino y mejor al de los cereales, principalmente por su mayor contenido de energía neta para lactancia (ENL; 6.57 a 7.32 MJ kg-1 MS). Los rendimientos de MS de las brásicas fueron similares a los observados en los forrajes tradicionales; sin embargo, por su alta composición nutricional las brásicas fueron iguales o superiores en producción de proteína cruda (PC) (1,608 a 2,986 kg ha-1) y ENL (62,819 a 84,044 MJ ha-1) a los forrajes tradicionales. En general, las brásicas forrajeras pueden incrementar el rendimiento de nutrientes respecto a los cereales y al trébol Alejandrino, especialmente en la producción de ENL (27.5 a 47.3 %).

Abstract The purpose of this study was to assess how ‘IAC 572’, ‘IAC 766’, and ‘Paulsen 1103’ rootstocks affected the duration of phenological phases, thermal demand, and chemical evolution throughout production cycle of the ‘BRS Vitória’ table grape cultivated in subtropical conditions. The duration of the following phenological stages was measured in days after pruning throughout two production seasons: budburst, flowering, setting, veraison, and harvest date. The thermal demand was determined using the degree-day concept. Titratable acidity, pH, soluble solids, and the maturation index were all measured throughout berry maturation. In general, the rootstocks ‘IAC 572’ and ‘IAC 766’ increased vine precocity in comparison to ‘Paulsen 1103’ during the early phenological phases. However, the vines grafted on ‘Paulsen 1103’ were earlier in the later phases, that is, at the veraison and at the harvest date, when compared to those grafted on the rootstocks ‘IAC 572’ and ‘IAC 766’. Under subtropical conditions, the total cycle period of the ‘BRS Vitória’ vine varied from 131 to 143 days, with thermal demands ranging from 1,545 to 1,725 DD. In comparison to the ‘IAC 572’ and the ‘IAC 766’, the ‘Paulsen 1103’ supplied the berries with a higher accumulation of soluble solids and a higher maturation index.

Resumo Objetivou-se avaliar o efeito dos porta-enxertos ‘IAC 572’, ‘IAC 766’ e ‘Paulsen 1103’ quanto à duração dos estádios fenológicos, à demanda térmica e à evolução química ao longo do ciclo de produção da uva ‘BRS Vitória’, cultivada em condições subtropicais. Durante dois ciclos de produção, foi quantificado, em dias após a poda, a duração das fases fenológicas: brotação, pleno florescimento, frutificação, início da maturação e data de colheita. A demanda térmica total foi calculdada utilizando-se do conceito de graus-dias. Durante a maturação das bagas, foram avaliados o pH, a acidez titulável, os teores de sólidos solúveis e o índice de maturação. De maneira geral, nos estádios fenológicos iniciais, os porta-enxertos ‘IAC 572’ e ‘IAC 766’ promoveram precocidade às videiras em relação ao ‘Paulsen 1103’. Contudo, nas fases finais, ou seja, no ínicio da maturação e na colheita, as videiras enxertadas sobre o ‘Paulsen 1103’ foram mais precoces quando comparadas às cultivadas sobre os porta-enxertos ‘IAC 572’ e ‘IAC 766’. A duração completa do ciclo da videira ‘BRS Vitória’, em condições subtropicais, variou de 131 a 143 dias, com demandas térmicas variando de 1.545 a 1.725 GD. O ‘Paulsen 1103’ propiciou às bagas maior acúmulo de sólidos solúveis e maior índice de maturação em relação ao ‘IAC 572’ e ao ‘IAC 766’.

ABSTRACT: Sheep production is expanding among small farmers in Southern Uruguay. Currently, Corriedale and Milchschaf are being used, but not Highlander. However, there is lack of experimental information regarding the relative performance of these breeds. We conducted an experiment where these three sheep breeds were run together at the Southern Regional Centre, located in the region in question. Wool, body, reproductive and lamb growth traits were recorded from 2015 to 2019. Results were used as a basis for the calculation of gross margins for each breed, which we calculated for a range of production and economic scenarios. For scenarios based on the results of the present study Highlander was the best performing breed. If it was assumed to be wool-less, it performed even better. In some scenarios Corriedale performed best, especially when the higher wool price it used to enjoy was assumed. However, fetching such a price in the foreseeable future is unlikely. We concluded that in the absence of wool-less sheep that perform in a manner similar to Highlander or Milchschaf in terms of reproduction and lamb growth, Highlander is currently the best option for small farmers in Southern Uruguay. Until now, Milchschaf has been the recommended breed for the region and production system in question. The recommendation should be reviewed, Highlander should be recommended instead, and the performance of wool-less breeds should be investigated. Results could be applicable to other temperate regions in Latin America where similar production systems exist or may be developed.

RESUMO: A produção de ovinos está se expandindo entre os pequenos produtores do Sul do Uruguai. Corriedale e Milchschaf estão sendo utilizados atualmente, mas não Highlander. Não obstante, há uma falta de informações experimentais sobre o desempenho relativo destas raças. Realizamos um experimento no qual estas três raças ovinas foram manejadas juntas no Centro Regional Sul, localizado na região em questão. As características de lã, corpo, reprodução e crescimento do cordeiro foram registradas de 2015 a 2019. Os resultados foram usados como base para calcular as margens brutas para cada raça, o que fizemos para uma série de cenários de produção e econômicos. Nos cenários baseados nos resultados deste estudo, a raça Highlander foi a que teve melhor desempenho. Se, se supunha que não tinha lã, seu desempenho era ainda maior. Em alguns cenários, Corriedale foi a raça com melhor desempenho, particularmente quando se supôs preços mais altos da lã, como os que se obtinham anos atrás. No entanto, é improvável que estes preços sejam atingidos novamente num futuro próximo. Concluímos que, na ausência de ovelhas sem lã, que tenham um desempenho semelhante ao Highlander ou Milchschaf em termos de reprodução e crescimento do cordeiro, Highlander é atualmente a melhor opção para os pequenos produtores do sul do Uruguai. Até agora, Milchschaf tem sido a raça recomendada para a região e para o sistema de produção em questão. Esta recomendação deve ser revista, o Highlander deve ser a raça recomendada, e o desempenho das raças sem lã deve ser investigado. Os resultados poderiam ser aplicáveis a outras regiões temperadas da América Latina onde sistemas de produção similares existem ou podem ser desenvolvidos.

ABSTRACT In Cuba, newborn screening (NBS) for cystic fibrosis (CF) was introduced in January 2019. The results from the first three years of the CF NBS program are presented. An IRT/IRT protocol was followed using a cut-off value of 50 ng/mL. In this period 281,717 neonates were screened, 2,197 samples had increased IRT values, and a second sample was necessary (recall rate=0.78%). In 686 (0.24%) neonates, IRT was still elevated, and they were referred for clinical evaluation. Twenty-one children were confirmed by sweat test and molecular biology. Eighteen newborns presented variant F508del. A false negative case was reported. Demographic data of 32,764 neonates were collected. The average age of sampling was six days with results available at 11 days of life, but 1.7% of the samples were collected 20 days after birth. The mean IRT value was 12.7±11.7 ng/mL (ranging 0-283 ng/mL) with a calculated 98.5 percentile value of 42.4 ng/mL. On average, the samples were processed five days after collection and two days after they were received at the laboratory. Although CF NBS program in Cuba is just beginning, it can be predicted that CF will be one of the most frequent inherited-metabolic diseases in the Cuban population.

ABSTRACT Introduction: Cuba is going through a changing context that impacts the family sphere. This requires new perspectives towards families from science and politics. The place that adolescents and young people occupy in the sphere of family and couples, and their modes of interaction, contributes to the resizing of youth policies. Methods: A mixed approach was used and the information resulting from the applied techniques was triangulated. The sample was representative by age groups and areas of residence. Gender and rights approaches were considered. Results and Discussion: Scientific information on adolescents and young people in the referred areas has been systematized. Modes of interaction of these populations were characterized according to affective relationships, information/orientation and participation in these spaces. The orientation program “Learning to live as a family and as a couple” was designed and implemented from the methodology of popular education. Conclusions: Problems related to these populations are studied, without singling out -sufficiently- their dynamics. This limits the possibilities of understanding interaction patterns that occur in these contexts and leads to the violation of some rights. Featuring adolescents and young people interactions on the family and the couple sphere was essential in order to develop some guidance actions for bringing into focus their most meaningful needs.

RESUMEN Introducción: Cuba transita por un contexto cambiante que impacta el escenario familiar. Ello exige nuevas miradas hacia las familias desde las Ciencias y la política. El lugar que ocupan adolescentes y jóvenes en los ámbitos de familia y pareja, y sus modos de interacción, contribuye al redimensionamiento de políticas de juventud. Métodos: Se utilizó un enfoque mixto y se realizó la triangulación de la información resultante de las técnicas aplicadas. La muestra fue representativa por grupos etarios y zonas de residencia. Se consideraron los enfoques de género y derechos. Resultados y Discusión: Sistematizada información científica sobre adolescentes y jóvenes en los ámbitos referidos. Fueron caracterizados modos de interacción de estas poblaciones atendiendo a relaciones afectivas, información/orientación y participación en estos espacios. Diseñado e implementado el programa de orientación “Aprendiendo a vivir en familia y pareja”, desde la metodología de la educación popular. Conclusiones, el estudio de problemáticas relacionadas con estas poblaciones, sin particularizar -suficientemente- en sus dinámicas, limita las posibilidades de comprender pautas de interacción que acontecen en estos contextos y propician la vulneración de algunos derechos. Caracterizar las interacciones de adolescentes y jóvenes en los escenarios de familia y pareja fue esencial para la acción de orientación, enfocada en sus necesidades más sentidas.

Abstract: The relationship between employment and the sustainable development of cities in Oaxaca, Mexico, during the period 2000-2019 is analyzed to visualize employment opportunities in the cities that will make it possible to cope with the economic crisis derived from the COVID-19 pandemic. The methodology of the statistical analysis of correlation and network theory is used for data analysis. One can infer that there is a high correlation between employment levels and the sustainable development of Oaxacan cities. These results show that despite the economic vulnerability that still persists in them, the cities analyzed have strengths and opportunities in their activities and infrastructure, which is conducive to promoting employment linked to sustainable development.

Resumen: En el presente artículo se analiza la relación existente entre la ocupación laboral y el desarrollo sostenible de las ciudades de Oaxaca, México, durante 2000-2019, para visualizar algunas oportunidades de ocupación en las ciudades que permitan enfrentar la crisis económica derivada de la pandemia de la COVID-19. Se utiliza la metodología del análisis estadístico de correlación y de la teoría de redes para el análisis de los datos. Se concluye que existe una alta correlación entre el nivel de ocupación y el desarrollo sostenible de las ciudades oaxaqueñas. Estos resultados muestran que las ciudades analizadas, a pesar de la vulnerabilidad económica que aún persiste en ellas, poseen fortalezas y oportunidades en sus actividades e infraestructura, lo que resulta favorable para impulsar en ellas la ocupación ligada al desarrollo sostenible.

Resumen: Introducción: Si bien la formación de enfermeros en Administración y Gestión tiene una importante repercusión en el presente y el futuro de la profesión, los métodos de enseñanza siguen siendo tradicionales en muchos casos. El aula invertida es un método ampliamente utilizado en la educación de enfermería, pero los estudios sobre su aplicación a la administración y gestión de enfermería son limitados. Método: Estudio cualitativo mediante cuestionario anónimo (preguntas dicotómicas y abiertas). Resultados: El 92 % de los estudiantes se mostró satisfecho con la metodología de enseñanza y el 92,9 % con la evaluación. Solo el 31,5 % lo había usado anteriormente, pero al 83 % le gustaría usarlo en más sujetos. Los estudiantes demostraron que la metodología utilizada había mejorado su opinión sobre el contenido y había aumentado su percepción útil del mismo. Conclusión: Los estudiantes participantes han demostrado estar satisfechos con el método de aula invertida. Estas estrategias de enseñanza pueden ayudar a motivar a los estudiantes de enfermería hacia la asignatura de Administración y Gestión de los Servicios de Enfermería, lo que puede animarlos a realizar una formación de posgrado y una práctica profesional en esta área.

Abstract: Introduction: Although the training of nurses in administration and leadership has an important repercussion on the present and the future of the profession, teaching methods are still traditional in many cases. Flipped classroom is a widely used method in nursing education but studies about its application to Nursing Administration and Management are limited. Method: Qualitative study by means of anonymous survey (dichotomous and open questions). Results: 92 % of students were shown to be satisfied with the teaching methodology and 92.9 % with the assessment. Only 31.5 % had used it previously but 83 % would like to use it in more subjects. The students showed that the methodology used had improved their opinion about the content and had increased their perception its usefulness. Conclusion: The participating students have been shown to be satisfied with flipped method and continuous assessment. These teaching strategies can help motivate nursing students towards the subject of Nursing Administration and Management, which can encourage them to pursue postgraduate training and professional practice in this area

Resumen Introducción: la capilaroscopia es un método no invasivo que permite observar la microvasculatura en el área periungueal. Los resultados informados pueden ser altamente variables entre distintos observadores. A lo largo del tiempo surgieron métodos cuantitativos y semicuantitativos para mejorar la reproducibilidad. Objetivos: conocer el nivel de acuerdo intra e interobservador al informar los diferentes patrones capilaroscópicos en individuos con diferente nivel de entrenamiento. Materiales y métodos: estudio de corte transversal. Participaron médicos reumatólogos especialistas y en formación que habían realizado previamente un curso virtual de capacitación en capilaroscopia. Recibieron 40 imágenes capilaroscópicas proyectadas en una presentación de PowerPoint y debían responder a través de un cuestionario digital. Se evaluó la concordancia de respuestas intra e interobservador. Resultados: se encontró un alto nivel de concordancia global con un kappa 0,66 IC 95% (0,63-0,70) p<0,0000. También en otros grupos como reumatólogos en formación: kappa 0,65 IC 95% (0,60-0,71) p=0,0000, y médicos reumatólogos: kappa 0,67 IC 95% (0,62-0,72) p=0,0000. Conclusiones: el nivel de concordancia encontrado fue globalmente alto, independientemente del nivel de entrenamiento de los profesionales, y de ser o no reumatólogo. La concordancia fue superior cuando se comparó a quienes tenían más de 4 años de experiencia en la realización de videocapilaroscopia.

Abstract Introduction: videoapillaroscopy is a non-invasive method that allows the observation of the microvasculature in the periungual area. Reported results can be highly variable between different observers. Over time, quantitative and semi-quantitative methods emerged to improve reproducibility. Objetives: to know the level of intra and interobserver agreement when reporting the different capillaroscopic patterns in individuals with different levels of training. Materials and methods: cross section study. Specialist rheumatologists and those in training who had previously completed a virtual capillaroscopy training course participated. They received 40 capillaroscopic images projected in a PowerPoint presentation and had to issue their response through a digital questionnaire. Concordance of intra and interobserver responses was evaluated. Results: a high level of global agreement was found with a kappa 0.66 CI 95% (0.63-0.70) p<0.0000, also in other groups such as rheumatologists in training: kappa 0.65 CI 95% (0.60-0.71) p=0.0000, physicians rheumatologists: kappa 0.67 95% CI (0.62-0.72) p=0.0000. Conclusions: the level of agreement found was globally high, regardless of the level of training of the professionals, and whether or not they were a rheumatologist. Concordance was higher when compared to those who had more than 4 years of experience performing videocapillaroscopy.
