RESUMEN La dieta de las tortugas de agua dulce Acanthochelys spixii y Hydromedusa tectifera es poco conocida en el extremo sur del Brasil. En este contexto se examinó el tracto digestivo de 21 individuos de A. spixii y 20 de H. tectifera provenientes de cuatro municipios del estado de Rio Grande do Sul, Brasil. Los ítems consumidos fueron identificados al nivel taxonómico más bajo posible, cuantificados y conservados en etanol de 70 °GL. Se obtuvieron las variables frecuencia de ocurrencia (F %) y el volumen porcentual (V %) de cada categoría de presa y se calculó el índice de importancia alimentaria (IAi %). Se analizó la amplitud del nicho trófico y la estrategia de alimentación de ambas especies. Las dietas se compararon usando la prueba de Mann-Whitney (P < 0,05). Ambas especies presentaron una estrategia de alimentación generalista, consumiendo principalmente insectos Hemiptera, Odonata, Coleoptera y Diptera. No hubo diferencias significativas en el volumen de ítems consumidos por ambas especies (Mann-Whitney, z = -0,387, P = 0,69). En relación con la amplitud de nicho trófico observamos valores bajos para ambas especies, 0,41 en A. spixii y 0,39 en H. tectifera, lo que sugiere una dieta más restringida con uniformidad en el consumo de alimentos, sin embargo, resaltamos que una dieta más restringida no sugiere una especialización trófica, ya que la disponibilidad de los elementos alimenticios tiene variación en el tiempo y el espacio. El estudio aportó información sobre la dieta de las especies de la región, generando datos que pueden utilizarse en programas de conservación de las especies y sus hábitats.

ABSTRACT Data about the diet of the freshwater turtles Acanthochelys spixii and Hydromedusa tectifera from southern Brazil populations remain little known. In this context, the digestive tract of 21 A. spixii and 20 of H. tectifera individuals from four municipalities in the state of Rio Grande do Sul, Brazil, were examined. The food items were identified at the lowest possible taxonomic level, quantified, and conserved in ethanol 70°GL. The frequency of occurrence (F %) and volume percentage (V %) were estimated, as well as the food importance index (IAi %). The range of the trophic niche and the feeding strategy of both species were analyzed. The diet of A. spixii and H. tectifera was compared through the Mann-Whitney test (P < 0.05). Both species presented a generalist food strategy, consuming mainly insects, represented by Hemiptera, Odonata, Coleoptera, and Diptera. There was no significant difference in the volume of items consumed by both species (Mann-Whitney test, z =-0.387, P = 0.69). Concerning the trophic niche range, we observed low values for both species, it was of 0.41 for A. spixii and 0.39 for H. tectifera suggesting a more restricted diet with uniformity in food consumption, however, we highlight that a more restricted diet does not suggest a trophic specialization, because the availability of food items have variation in time and space. The study contributed information on the diet of species in the region, generating data that can be used in programs for the conservation of species and their habitats.

Resumo Objetivo Avaliar aspectos emocionais e clínicos observados em mulheres com doença trofoblástica gestacional (DTG) acompanhadas em um centro de referência (CR), por equipe multiprofissional. Método Estudo de coorte retrospectivo nos prontuários clínicos de 186 mulheres comDTG, e dos aspectos emocionais (AE) observados nessas mulheres pela equipe de psicólogas e registrados nos 389 grupos de apoio (GAs), ocorridos de 2014 a 2018. Resultados As pacientes eram jovens (idade média 31,2 anos), 47% sem filhos vivos, 60% tinham desejado ou planejado esta gravidez e 50% delas participaram de dois ou mais GAs. A maioria (n=137-73,6%) apresentou remissão espontânea da gestação molar com mediana de 10 semanas e um tempo total de seguimento de 7 meses. Quarenta e nove mulheres (26,3%) evoluíram para neoplasia trofoblástica gestacional (NTG); amediana para atingir a remissão após tratamento comquimioterapia foi de 19 semanas e o tempo total de seguimento foi de 36 meses. Os AE incluíram variados graus de ansiedade e depressão, mais evidentes em 9,1% das nossas pacientes; tais AE tenderam a ocorrer mais em mulheres com idade acima de 40 anos (p=0,067), com menor escolaridade (p=0,054), com evolução para NTG (p=0,018), e nas que necessitaram de tratamento quimioterápico com regime de múltiplos agentes (p=0,028), ou de histerectomia complementar ao tratamento clínico (p=0,001). Conclusão Este estudo mostrou presença de vários AE associados em todos os tipos de DTG. Destaca tambéma importância de umatendimento psicológico especializado, somente encontrado nos CR, que é essencial para ajudar na recuperação da saúde mental dessas mulheres.

Abstract Objective To evaluate the emotional and clinical aspects observed in women with gestational trophoblastic disease (GTD) followed-up in a reference center (RC) by a multidisciplinary team. Methods Retrospective cohort study of the clinical records of 186 women with GTD and of the emotional aspects (EA) observed in these women by a teamof psychologists and reported by the 389 support groups conducted from 2014 to 2018. Results The women were young (mean age: 31.2 years), 47% had no living child, 60% had planned the pregnancy, and 50% participated in two or more SG. Most women (n=137; 73.6%) reached spontaneous remission ofmolar gestation in a median time of 10 weeks and had a total follow-up time of seven months. In the group of 49 women (26.3%) who progressed to gestational trophoblastic neoplasia (GTN), time to remission after chemotherapy was 18 weeks, and total follow-up time was 36 months. EA included different levels of anxiety and depression,more evident in 9.1% of the women; these symptoms tended to occur more frequently in women older than 40 years (p=0.067), less educated (p=0.054), and whose disease progressed to GTN (p=0.018), as well as in those who had to undergo multi-agent chemotherapy (p=0.028) or hysterectomy (p=0.001) adjuvant to clinical treatment. Conclusion This study found several EA in association with all types of GTD. It also highlights the importance of specialized care only found in a RC, essential to support the recovery of the mental health of these women.

Abstract Objective: To estimate the prevalence of childhood obesity in Brazil by means of a systematic review of representative studies. Sources: We searched for population-based studies that assessed obesity in Brazilian children aged < 10 years in MEDLINE, EMBASE, Scopus and other sources up to September, 2019. Paired researchers selected studies, extracted data and assessed the quality of these studies. Meta-analysis of prevalence and confidence interval (95% CI) was calculated, weighted by the population sizes using Freeman-Tukey double-arccosine transformation. Heterogeneity (I2) and publication bias were investigated by meta-regression and Egger’s test, respectively. Summary of the findings: 53 studies were included (n = 122,395), which were held from 1986 to 2015 and limited mainly due to inadequate response rates. Prevalence of obesity in the threedecade period was of 8.2% ([95% CI]: 8.1–8.4%, I2 = 98.5%). Higher prevalence was observed in boys (9.7% [9.4–9.9%], I2 = 97.4%) than girls (7.3% [7.1 7.5%], I2 = 96.1%). Prevalence increased according to the decade (1990: 6.5% [6.0–7.0 %], I2 = 96.8%; 2000: 7.9% [7.7–8.0 %], I2 = 98.8%; 2010: 12.0% [11.5–12.6 %], I2 = 95.8%), and Brazilian region (Northeast: 6.4% [6.2−6.7%], I2 = 98.1%; North: 6.7% [6.3−7.2%], I2 = 98.8%; Southeast:10.6% [10.2−11.0%], I2 = 98.2%; South: 10.1 [9.7−10.4%], I2 = 97.7%). Heterogeneity was affected by age and region (p < 0.05) and publication bias was discarded (p = 0.746). Conclusion: For every 100 Brazilian children, over eight had obesity in the three-decade period and 12 in each 100 had childhood obesity in more recent estimates. Higher prevalence occurred in boys, recent decades and more developed Brazilian regions.

Resumo: O presente artigo propõe uma reflexão sobre as questões de gênero que envolvem as práticas da palhaçaria feminina, a partir do convívio e de entrevistas com um grupo de mulheres palhaças no Brasil. Trabalha-se a ideia de que os discursos sociais forjam os corpos e os padrões de gênero e, portanto, perpassam os processos criativos na palhaçaria. Com base no conceito de práticas parodísticas desenvolvido por Judith Butler, este trabalho busca pensar nos processos da palhaçaria feminina no seu caráter de paródia de si e em suas reverberações na criação de uma comicidade crítica e não autodepreciativa. Propõe-se o conceito de paródia a partir dos trabalhos de Judith Butler, Linda Hutcheon e Giorgio Agamben como forma de delinear a noção de paródia na qualidade de distanciamento crítico e na possibilidade de afetar os modos de subjetivação das artistas.

Abstract: This paper proposes a reflection on gender issues involving female clowning practices, based on the coexistence and interviews with a group of female clowns in Brazil. It develops the idea that social discourses forge bodies and gender standards, therefore crossing the creative processes in clowning. Founded on the concept of parodistic practices developed by Judith Butler, this work aims to think on the processes of female clowning in its character of parody of oneself, as well as on its reverberations in the creation of a critic and non-self-derogatory comicality. The concept of parody is proposed based on the works of Judith Butler, Linda Hutcheon and Giorgio Agamben as a way of outlining the notion of parody in the quality of critical detachment, and in the possibility of affecting the female artists’ modes of subjectivation.

Resumo As aves atuam como hospedeiros para uma ampla variedade de parasitos, muitos destes ainda desconhecidos. Foram examinadas 28 aves, provenientes dos municípios de Pelotas, Capão do Leão e Rio Grande. A coleta, preparação e identificação dos helmintos seguiu bibliografia específica. A assembleia de helmintos foi analisada através dos índices de prevalência (P%), intensidade média de infecção (IMI) e abundância (AM). A assembleia de helmintos de P. infuscatus estava composta por Nematoda: Hystrichis acanthocephalicus , Dioctophyme renale (larva), Porrocaecum heteropterum , Baruscapillaria sp., Aproctella carinii , Paradeletrocephalus minor, Cyathostoma sp.; Digenea: Echinostomatidae gen. sp., Tanaisia valida, Athesmia sp. e Megalacanthus sp. (Cestoda). As espécies mais prevalentes foram: H. acanthocephalicus, P. heteropterum , Megalacanthus sp. e Echinostomatidae gen. sp. A maior IMI e AM foi de Megalacanthus sp., onde observou-se diferença significativa na prevalência de H. acantocephalicus em hospedeiros fêmeas. Os helmintos Echinostomatidae gen. sp., T. valida, Athesmia sp., Cyathostoma sp., A. carinii, P. minor, D. renale (larva), Baruscapillaria sp., e Megalacanthus sp. são registrados pela primeira vez em P. infuscatus no Brasil.

Abstract Birds act as hosts for a variety of parasites, many of these are unreported. The literature provides scant information on the helminth fauna of Phimosus infuscatus. The presence of helminths were investigate in 28 birds from Pelotas, Capão do Leão, and Rio Grande in Rio Grande do Sul. The preparation and identification of helminths followed protocols. Prevalence (P%), mean intensity of infection (MII), and mean abundance (MA) were estimated. The following helminths were found: Hystrichis acanthocephalicus , Dioctophyme renale (larva), Porrocaecum heteropterum , Baruscapillaria sp., Aproctella carinii , Paradeletrocephalus minor, and Cyathostoma sp. (Nematoda); Echinostomatidae gen. sp., Tanaisia valida, and Athesmia sp. (Trematoda: Digenea) and Megalacanthus sp. (Cestoda). The most prevalent species were H. acanthocephalicus, P. heteropterum, Megalacanthus sp., and Echinostomatidae gen. sp. and Megalacanthus sp. had the highest MII and MA. There was a significant difference in the prevalence of H. acantocephalicus between female and male bird hosts. We report Echinostomatidae gen. sp., T. valida, Athesmia sp., Cyathostoma sp., A. carinii, P. minor, D. renale (larva), Baruscapillaria sp., and Megalacanthus sp. for the first time in P. infuscatus in Brazil.

Resumen La transmisión congénita de la enfermedad de Chagas ha sido poco estudiada en Colombia y existen pocos procedimientos rutinarios en el sistema de salud para el manejo de esta enfermedad. Por ello se desarrolló un consenso de expertos dirigido a generar recomendaciones de diagnóstico y tratamiento de Chagas con- génito y orientación a mujeres en edad fértil. Con ese propósito se realizó una búsqueda extensiva de la literatura, empleando una combinación de términos Mes (Chagas, Chagas congénito, prevención, control, diagnóstico, tratamiento y embarazo) para reflejar el estado del arte en cada tema de interés. Después de ello, se leyeron los resúmenes y aquellos seleccionados para análisis del texto completo. La literatura relevante se sintetizo, clasifico y organizo en tablas y se presentó al panel de expertos, el cual estaba constituido por 30 profesionales en diferentes áreas. Mediante la metodología Delphi se realizaron 2 rondas de cuestionarios virtuales y una reunión presencial en los cuales se evaluaron los niveles de acuerdo entre los participantes. Los puntos con falta de consenso durante las 2 rondas virtuales se expusieron durante las mesas de discusión en la ronda presencial. La evidencia utilizada se adaptó a las particularidades nacionales según el caso y se aprobó el contenido del documento final. Se propone que estas recomendaciones sean usadas por profesionales de la salud en Colombia.

Abstract Congenital transmission of Chagas disease has not been extensively studied in Colombia, and there are no standardized processes in the health system regarding the specific diagnosis, treatment and follow-up of this disease. To generate recommendations on congenital Chagas disease and Chagas in women of childbearing age in Colombia, a consensus of experts was developed. An extensive literature search through the Medline database was carried out using the MeSH terms: «Chagas disease/congenital», «prevention and control», «diagnosis», «therapeutics» and «pregnancy». Appropriate abstracts were selected and the full texts were analyzed. The relevant information was synthesized, classified, and organized into tables and figures and was presented to a panel of experts, which was composed of 30 professionals from various fields. Based on the Delphi methodology, three rounds of consultation were conducted. The first and second rounds were based on electronic questionnaires that measured the level of consensus of each question among the participants. The third round was based on a face-to-face discussion focusing on those questions without consensus in the previous consultations. The evidence was adapted to national circumstances on a case-by-case basis, and the content the final document was approved. These recommendations are proposed for use in routine medical practice by health professionals in Colombia.

ABSTRACT Objective: This paper sought to determine the accumulated incidence and analyze the risk factors associated with the development of weakness acquired in the intensive care unit and its relationship to inspiratory weakness. Methods: We conducted a prospective cohort study at a single center, multipurpose medical-surgical intensive care unit. We included adult patients who required mechanical ventilation ≥ 24 hours between July 2014 and January 2016. No interventions were performed. Demographic data, clinical diagnoses, the factors related to the development of intensive care unit -acquired weakness, and maximal inspiratory pressure were recorded. Results: Of the 111 patients included, 66 developed intensive care unit -acquired weakness, with a cumulative incidence of 40.5% over 18 months. The group with intensive care unit-acquired weakness were older (55.9 ± 17.6 versus 45.8 ± 16.7), required more mechanical ventilation (7 [4 - 10] days versus 4 [2 - 7.3] days), and spent more time in the intensive care unit (15.5 [9.2 - 22.8] days versus 9 [6 - 14] days). More patients presented with delirium (68% versus 39%), hyperglycemia > 3 days (84% versus 59%), and positive balance > 3 days (73.3% versus 37%). All comparisons were significant at p < 0.05. A multiple logistic regression identified age, hyperglycemia ≥ 3 days, delirium, and mechanical ventilation > 5 days as independent predictors of intensive care unit-acquired weakness. Low maximal inspiratory pressure was associated with intensive care unit-acquired weakness (p < 0.001), and the maximum inspiratory pressure cut-off value of < 36cmH2O had sensitivity and specificity values of 31.8% and 95.5%, respectively, when classifying patients with intensive care unit-acquired weakness. Conclusion: The intensive care unit acquired weakness is a condition with a high incidence in our environment. The development of intensive care unit-acquired weakness was associated with age, delirium, hyperglycemia, and mechanical ventilation > 5 days. The maximum inspiratory pressure value of ≥ 36cmH2O was associated with a high diagnostic value to exclude the presence of intensive care unit -acquired weakness.

RESUMEN Objetivo: Conocer la incidencia acumulada y analizar los factores riesgo asociados al desarrollo de debilidad adquirida en la unidad de cuidados intensivos y su asociación con la debilidad inspiratoria. Métodos: Estudio de cohorte prospectivo en un solo centro, unidad de cuidados intensivos médico-quirúrgica polivalente. Se incluyeron pacientes adultos, que hayan requerido ventilación mecánica ≥ 24 horas entre julio de 2014 y enero de 2016. No hubo intervenciones. Se registraron datos demográficos, diagnóstico clínico y factores relacionados con el desarrollo de debilidad adquirida en la unidad de cuidados intensivos y Presión inspiratoria máxima. Resultados: Ciento once pacientes incluidos, 66 desarrollaron debilidad adquirida en la unidad de cuidados intensivos, con una incidencia acumulada del 40,5% en 18 meses. El grupo con debilidad adquirida en la unidad de cuidados intensivos presentó mayor edad (55,9 ± 17,6 versus 45.8 ± 16.7), además de más días con ventilación mecánica (7 [4 - 10] versus 4 [2 - 7,3]), más días en unidad de cuidados intensivos (15,5 [9,2 - 22,8] versus 9 [6 - 14]). Hubo más pacientes con delirio (68% versus 39%), con hiperglucemia > 3 días (84% versus 59%); y con balance positivo > 3 días (73,3% versus 37%). Todas las comparaciones fueron significativas con p < 0,05. La regresión logística múltiple identificó a la edad, la hiperglucemia ≥ 3 días, el delirio y la ventilación mecánica > 5 días como predictores independientes para debilidad adquirida en la unidad de cuidados intensivos. La presión inspiratoria máxima baja se asoció a debilidad adquirida en la unidad de cuidados intensivos (p < 0,001) y el punto de corte presión inspiratoria máxima < 36cmH2O obtuvo una sensibilidad y especificidad del 31,8% y 95,5% para clasificar al grupo con debilidad adquirida en la unidad de cuidados intensivos. Conclusión: La debilidad adquirida en la unidad de cuidados intensivos es una condición con un alta incidencia en nuestro medio. El desarrollo de debilidad adquirida en la unidad de cuidados intensivos se asoció a la edad, delirio, hiperglucemia y la ventilación mecánica > 5 días. La presión inspiratoria máxima ≥ 36cmH2O demostró un alto valor diagnóstico para descartar la presencia de debilidad adquirida en la unidad de cuidados intensivos.

Abstract: Due to mounting evidences of interaction between Hansen's bacilli with endothelial cells and the paucity of studies addressing the presence of nailfold capillaroscopic alterations in patients with Hansen's disease, a study was carried out in order to verify the presence of capillaroscopic alterations in patients with leprosy in its various forms and its correlation with clinical parameters. Ten patients were evaluated at a specialized university service. Sixty percent of those had some capillaroscopic change, such as micro-hemorrhages, ectatic, bushy and corkscrew capillaries. Such changes were unspecific, which suggests there is not a specific pattern for this disease.

Both soil phosphorus (P) and soil acidity are the key factors in soil fertility management and often limits crop production in subtropical agriculture. The objective of this study was to evaluate the response of lime and different P rates on sugarcane variety and their interactive effect on the sugar cane borer attack. A three factorial experiment containing, two sugarcane varieties i. e., (SP81-3250 and RB-956911); with and without application of agricultural lime (3.5 t ha-1) and four P rates i. e., (0, 20, 40 and 60 kg P2O5 ha-1) was carried out at the research field area of Federal University of Santa Maria, RS, Brazil during 2011-12. It assessed a) sugarcane stalk length, b) stem diameter; c) number of internodes, d) number of stalk ha-1, e) stalk yield, f) °Brix and g) Intensity of infestation Index. Results indicated that, the stalk yields of RB-956911 and SP81-3250 was 106.6 and 139.8 Mg ha-1, respectively. The °Brix was between 18.60 % and 18.00 %, respectively. The Intensity of infestation Index was 2.76 % for the RB-956911 and 3.65 % for the SP81-3250. The lime application showed significant results only on the borer attack. Phosphorus application increased the sugarcane yield from 105.9 Mg ha-1 to 136.5 Mg ha-1 with 60 kg of P2O5 ha-1. The application of phosphorus increased sugarcane productivity but it does not contribute which increase the borer attack.

Los niveles de fósforo y la acidez del suelo pueden limitar la producción agrícola en la agricultura subtropical. El objetivo del trabajo fue evaluar el efecto de la cal agrícola y del fósforo sobre dos variedades de caña de azúcar, y el ataque del barrenador. La investigación se realizó en el área experimental de la Universidad Federal de Santa María, Brasil durante 2011-2012. Fue conducido un experimento trifactorial, con dos variedades de caña de azúcar (SP81-3250 y RB-956911), con y sin aplicación de cal agrícola (3,5 Mg ha-1) y cuatro dosis de fósforo (0, 20, 40 y 60 kg de P2O5 ha-1). Se evaluaron: a) longitud de la parte industrial, b) diámetro de la base del tallo, c) número de entrenudos, d) número total de tallos, e) rendimiento, f) °Brix, y g) Índice de Intensidad de Infestación del taladrador. El rendimiento de RB-956911 y SP81-3250 fue de 106,6 y 139,8 Mg ha-1, respectivamente, el oBrix de 18,6 % y 18,0 %. El Índice de Intensidad de Infestación fue de 2,76 % para RB-956911 y de 3,65 % para SP81-3250. La cal agrícola influyó solamente sobre el ataque del taladrador. El fósforo aumentó la producción de la caña, pasando de 105,9 Mg ha-1 a 136,5 Mg ha-1 con la aplicación de 60 kg de P2O5 ha-1. La aplicación de fósforo aumentó la producción de caña de azúcar, sin aumentar el ataque del taladrador.

To obtain high productivity in sugar cane, all available technologies and tactics seeking to improve product quality in harmony with the environment should be applied. The objective of this work was to evaluate two sugarcane varieties and to determine its response to nitrogen rates and their effect on sugar cane borer attack, in field conditions. The experiment was carried out at the research field area of Federal University of Santa Maria, RS, Brazil. A two factorial experiment containing two sugarcane varieties (RB-956911 and SP81-3250), and four N rates (0, 40, 80 and 120 kg N ha-1). We assessed a) sugarcane stalk length, b) stem base diameter; c) number of internodes, d) number of stalk ha-1, e) stalk yield, f) °Brix g) Intensity of Infestation (II), and h) Intensity of infestation Index (III). Results indicated that the stalk yields of RB-956911 and SP81-3250 was 111,730 and 126,752 Mg ha-1, respectively. The °Brix was between 18.60 and 18.15, respectively. The II and III was not affected by variety, with II between entre 3.96% y 2.88% and III between 4,62% y 3.03%, respectively for sugarcane variety RB-956911 and SP81-3250. Nitrogen fertilization increases stalk yield, decrease °Brix, and does not affect sugarcane borer attack.

Para la obtención de alta productividad en caña de azúcar se deben aplicar tecnologías y técnicas que mejoren la calidad del producto en armonía con el ambiente, por ello el objetivo del trabajo fue evaluar el efecto de un fertilizante nitrogenado sobre la producción de dos cultivares de caña de azúcar y el ataque del taladrador, en condiciones de campo. Se realizó en el área experimental del Departamento de Suelos de la Universidad Federal de Santa María, RS, Brasil. El diseño experimental fue bi factorial, siendo el primer factor dos cultivares (RB-956911 y SP81-3250) y, el segundo factor la aplicación de cuatro dosis de nitrógeno (0, 40, 80 y 120 kg ha-1). Se evaluó: a) longitud de la parte industrial (LPI), b) diámetro de la base del tallo, c) el número de entrenudos, d) número de tallos ha-1, e) rendimiento, f) Grados (°) Brix, g) Intensidad de Infestación (II) y h) Índice de Intensidad de Infestación (III). El rendimiento de los cultivares RB-956911 y SP81-3250 fue de 111.730 y 126.752 Mg ha-1, respectivamente, el °Brix de 18,60% y 18,15%, respectivamente. La II y el III no fueron afectados por el cultivar, presentando valores de II entre 3,96% y 2,88% y de III entre 4,62% y 3,03%, respectivamente para el cultivar RB-956911 y SP81-3250. La aplicación de nitrógeno aumenta la producción de caña de azúcar, disminuye el °Brix y no influencia en el ataque del taladrador de la caña de azúcar.

La transmisión congénita de la enfermedad de Chagas ha sido poco estudiada en Colombia y existen pocos procedimientos rutinarios en el sistema de salud para el manejo de esta enfermedad. Por ello se desarrolló un consenso de expertos dirigido a generar recomendaciones de diagnóstico y tratamiento de Chagas congénito y orientación a mujeres en edad fértil. Con ese propósito se realizó una búsqueda extensiva de la literatura, empleando una combinación de términos MeSH (Chagas, Chagas congénito, prevención, control, diagnóstico, tratamiento y embarazo) para reflejar el estado del arte en cada tema de interés. Después de ello, se leyeron los resúmenes y aquellos seleccionados para análisis del texto completo. La literatura relevante se sintetizó, clasificó y organizó en tablas y se presentó al panel de expertos, el cual estaba constituido por 30 profesionales en diferentes áreas. Mediante la metodología Delphi se realizaron 2 rondas de cuestionarios virtuales y una reunión presencial en los cuales se evaluaron los niveles de acuerdo entre los participantes. Los puntos con falta de consenso durante las 2 rondas virtuales se expusieron durante las mesas de discusión en la ronda presencial. La evidencia utilizada se adaptó a las particularidades nacionales según el caso y se aprobó el contenido del documento final. Se propone que estas recomendaciones sean usadas por profesionales de la salud en Colombia.

Congenital transmission of Chagas disease has not been extensively studied in Colombia, and there are no standardized processes in the health system regarding the specific diagnosis, treatment and follow-up of this disease. In order to generate recommendations on congenital Chagas disease and Chagas in women of childbearing age in Colombia, a consensus of experts was developed. An extensive literature search through the Medline database was carried out using the MeSH terms: " Chagas disease/congenital " , " prevention and control " , " diagnosis " , " therapeutics " and " pregnancy " . Appropriate abstracts were selected and the full texts were analyzed. The relevant information was synthesized, classified, and organized into tables and figures and was presented to a panel of experts, which was composed of 30 professionals from various fields. Based on the Delphi methodology, three rounds of consultation were conducted. The first and second rounds were based on electronic questionnaires that measured the level of consensus of each question among the participants. The third round was based on a face-toface discussion focusing on those questions without consensus in the previous consultations. The evidence was adapted to national circumstances on a case-by-case basis, and the content the final document was approved. These recommendations are proposed for use in routine medical practice by health professionals in Colombia.

A ehrlichiose monocítica equina (EME) na região Sul do Rio Grande do Sul tem demonstrado ser importante nas criações de cavalos Crioulos. A enfermidade foi relatada e diagnosticada como causa de diarreia, prejuízos com tratamentos e com a morte de equinos não estabulados, sendo apontada como um fator limitante na criação de equinos em algumas regiões. O modo de transmissão pela via oral, intermediada por trematódeos em ambientes aquáticos, tem sido sustentado. Caracóis dulciaquícolas estão envolvidos como hospedeiros intermediários de trematódeos albergadores de Neorickettsia risticii. Um total de 16.846 caracóis Heleobia foi coletado nos municípios de Arroio Grande, Rio Grande, Palmares do Sul e Santa Vitória do Palmar, 92,2% dos quais foram encontrados nas raízes de aguapés (Eichornea spp.). A frequência de trematódeos presentes nos caracóis variou de 2,3 a 12,8% nas propriedades coletadas. Foram encontrados três tipos de cercárias, morfotipo 1, morfotipo 2 e morfotipo 3, e dois morfotipos de metacercárias nos caracóis. Um total de 357 insetos da ordem Odonata foi coletado, fases de metacercárias foram encontradas no tegumento da subordem Anisoptera com frequência de 5,3%. Mais estudos são necessários para identificar as fases larvais encontradas, bem como para conhecer o hospedeiro definitivo, identificar o parasito adulto e a relação de seu ciclo de vida com a ocorrência da ehrlichiose monocítica equina.

The equine monocytic ehrlichiosis in the region South of the Rio Grande do Sul has demonstrated to be important in the creations of Crioulo horses. It has been reported as cause of diarrhea in equine not surround and as cause of losses with treatments and death of the animals, being pointed as a limited factor in the range breeding in some regions. The way of transmission for the oral way, intermediated for trematodes in aquatic environments, has been supported. Freshwater snails are involved as intermediate hosts of trematodes and harbor of the Neorickettsia risticii. A total of 16,846 Heleobia snails had been collected in the cities of Arroio Grande, Rio Grande, Palmares do Sul and Santa Vitoria do Palmar, 92.2% of which had been found in the roots of aquatics plants (Eichornea spp.). The frequency of trematodes present in the snails varied of 2.3 to 12.8% in the collected regions. Three types of cercariae were found, morphology type 1, morphology type 2 and morphology type 3, and two morphologic type of metacercariae of the snails. A total of 357 insects of the Odonata order were collected, stages of metacercariae had been found in the tissues of suborder Anisoptera with 5.3% of frequency. More studies are necessary for identification of the joined larval phases, as well as knowing the host definitive and identifying the adult parasite and the relation of its cycle of life with the occcurrence of equine monocytic ehrlichiosis.

ORIENTATION: Questionnaires, particularly the Utrecht Work Engagement Scale (UWES-17), are an almost standard method by which to measure work engagement. Conflicting evidence regarding the dimensionality of the UWES-17 has led to confusion regarding the interpretation of scores. RESEARCH PURPOSE: The main focus of this study was to use the Rasch model to provide insight into the dimensionality of the UWES-17, and to assess whether work engagement should be interpreted as one single overall score, three separate scores, or a combination. MOTIVATION FOR THE STUDY: It is unclear whether a summative score is more representative of work engagement or whether scores are more meaningful when interpreted for each dimension separately. Previous work relied on confirmatory factor analysis; the potential of item response models has not been tapped. RESEARCH DESIGN: A quantitative cross-sectional survey design approach was used. Participants, 2429 employees of a South African Information and Communication Technology (ICT) company, completed the UWES-17. MAIN FINDINGS: Findings indicate that work engagement should be treated as a unidimensional construct: individual scores should be interpreted in a summative manner, giving a single global score. PRACTICAL/MANAGERIAL IMPLICATIONS: Users of the UWES-17 may interpret a single, summative score for work engagement. Findings of this study should also contribute towards standardising UWES-17 scores, allowing meaningful comparisons to be made. CONTRIBUTION/VALUE-ADD: The findings will benefit researchers, organisational consultants and managers. Clarity on dimensionality and interpretation of work engagement will assist researchers in future studies. Managers and consultants will be able to make better-informed decisions when using work engagement data.

Os autoanticorpos possivelmente influenciam as manifestações clínicas da esclerose sistêmica (ES). Essa correlação clínico-sorológica, associada à insuficiência de casos de concomitância de autoanticorpos, originou o paradigma histórico de que seriam mutuamente excludentes. Porém, pode-se questionar essa tese. Poderia a multiplicidade de autoanticorpos significar a coexistência de duas patologias distintas? Por outro lado, se assumidos como anticorpos específicos de uma doença única, essa multiplicidade seria um evento aleatório ou representaria um subgrupo distinto de pacientes, com características clínicas, patogênicas e imunogenéticas próprias? A prevalência de autoanticorpos na ES precoce é elevada. Entretanto, a duplicidade do anticorpo anticentrômero (AAC) e do anticorpo antitopoisomerase 1 (AAT) é um evento raro. Já a coexistência de AAC, AAT e anticorpo anti-RNA polimerase (anti-RNA-P) III ainda não foi descrita em um paciente isolado. Neste relato, com positividade para AAC, AAT e anti-RNA-P III, notamos manifestações vasculares precoces e posterior comprometimento cutâneo limitado. Este parece ser o primeiro relato de concomitância de três autoanticorpos específicos em um paciente com ES. Acreditamos que essa coexistência representa um subgrupo sorológico raro de uma única doença, com possível valor clínico e prognóstico - porém, ainda há necessidade de confirmação.

Autoantibodies possibly influence clinical manifestations of systemic sclerosis (SSc). This clinical-serological correlation, associated with the paucity of autoantibodies concomitance, gave rise to the historical paradigm of autoantibodies mutual exclusivity. However, one can question this assumption. Does autoantibodies concomitance mean coexistence of two different entities? On the other hand, if considered a unique disease, is this phenomenon a random event or does it represent a distinct subgroup of patients, with peculiar clinical, pathogenic, and immunogenetic characteristics? The autoantibodies' prevalence in early SSc is high. However, anti-centromere antibody (ACA) and antitopoisomerase 1 antibody (ATA) duplicity is a rare event. Similarly, the ACA, ATA, and anti-RNA polymerase (anti-RNA-P) III coexistence have not been described yet in single patient. In the reported case, with ACA, ATA, and anti-RNA-P III positivity, we have noted early vascular manifestations and late limited cutaneous involvement. This is, to our knowledge, the first report of three concomitant specific autoantibodies in a patient with SSc. We do believe this coexistence represents a rare serologic subgroup of a unique disease, with possible clinical and prognostic value, although this remains to be confirmed.
