Riesgo alto y muy alto de fracturas osteoporóticas en mujeres chilenas / High and very high risk of osteoporotic fractures in Chilean women

Objetivos: evaluar la aplicación de los umbrales de intervención basados en FRAX en mujeres chilenas. Recategorizar elriesgo de fractura osteoporótica para optimizar la selección de mujeres elegibles para intervención.Métodos: seleccionamos de la Encuesta Nacional de Salud (ENS) 2016-2017 (tercera versión) 1782 mujeres de 50 y másaños. Calculamos la probabilidad de fracturas osteoporóticas mayores y fracturas de cadera utilizando el modelo FRAXchileno. Calculamos la proporción de mujeres elegibles para tratamiento y evaluación de la densidad mineral ósea aplicandoumbrales de intervención específicos por edad de 50 a 90 años y un umbral híbrido que combina umbrales dependientes dela edad hasta los 75 años y, a partir de entonces, un umbral fijo con una única probabilidad de fractura hasta los 90 años.Resultados: veintidós mujeres (1,23 %) tenían una fractura previa y eran elegibles para tratamiento por este motivo.Utilizando umbrales específicos por edad, otras 33 mujeres fueron elegibles para tratamiento porque la probabilidad defractura osteoporótica mayor estaba por encima del umbral superior de evaluación. En 1107 (62,12 %) mujeres, se recomienda medir la densidad mineral ósea para poder recalcular el FRAX con la inclusión de la densidad mineral ósea del cuellofemoral. Con el umbral híbrido, otras 44 (3,69 %) mujeres fueron elegibles para el tratamiento y se recomendó la mediciónde la densidad ósea en 1169 mujeres (65,50 %). Si el tratamiento se asignaba solo con FRAX sin densidad mineral ósea,el número de mujeres elegibles para el tratamiento era de 70 (5,15 %) con un umbral de intervención específico para laedad y de 120 (6,72 %) con el umbral híbrido.Conclusiones: el umbral híbrido identifica más mujeres elegibles para tratamiento que los umbrales específicos poredad. La probabilidad promedio de fractura fue mayor con el umbral híbrido. Sobre esta base, nuestra posición es que serecomiende el umbral híbrido.(AU)

Physician utilization in prehospital emergency medical services in Europe: an overview and comparison. / Visión general y comparación de la presencia de médicos en los servicios de emergencias médicas prehospitalarios en Europa.

OBJECTIVES: National and regional systems for emergency medical care provision may differ greatly. We sought to determine whether or not physicians are utilized in prehospital care and to what extent they are present in differentEuropean countries. MATERIAL AND METHODS: We collected information on 32 European countries by reviewing publications and sending questionnaires to authors of relevant articles as well as to officials of ministries of health (or equivalent), representatives of national societies in emergency medicine, or well-known experts in the specialty. RESULTS: Thirty of the 32 of European countries we studied (94%) employ physicians in prehospital emergency medical services. In 17 of the 32 (53%), general practitioners also participate in prehospital emergency care. Emergency system models were described as Franco-German in 27 countries (84%), as hybrid in 17 (53%), and as Anglo-American in 14 (44%). Multiple models were present simultaneously in 17 countries (53%). We were able to differentiate between national prehospital emergency systems with a novel classification based on tiers reflecting the degree of physician utilization in the countries. We also grouped the national systems by average population and area served. CONCLUSION: There are notable differences in system designs and intensity of physician utilization between different geographic areas, countries, and regions in Europe. Several archetypal models (Franco-German, hybrid, and Anglo- American) exist simultaneously across Europe.

OBJETIVO: Los sistemas nacionales y regionales de prestación de atención médica a las emergencias pueden diferir mucho entre sí. Se buscó dilucidar la presencia de médicos en la atención prehospitalaria y su implantación en los diferentes países europeos. METODO: Se analizaron los datos de 32 países europeos recogidos mediante la revisión de artículos publicados y a través de cuestionarios enviados a los autores de artículos científicos pertinentes, funcionarios del ministerio de sanidad (o equivalente), representantes de sociedades nacionales de medicina de urgencias o expertos reconocidos en medicina de urgencias. RESULTADOS: Treinta de los 32 países europeos investigados (94%) disponen de médicos en los servicios de emergencias prehospitalarios. En 17 de 32 (53%), los médicos generalistas también participan en la atención a las emergencias prehospitalarias. Los modelos de los sistemas de emergencias médicas (SEM) se describieron como francoalemanes en 27 países (84%), híbridos en 17 (53%) o angloamericanos en 14 (44%). En 17 países (53%), coexistían diferentes modelos. Utilizando una nueva forma de clasificación por niveles, basada en la población media y el área atendida por el SEM prehospitalario, se pudieron diferenciar claramente los diferentes modelos existentes. CONCLUSIONES: Se observan notables diferencias en los diseños de los SEM y en la presencia de los médicos entre las diferentes áreas geográficas, países y regiones de Europa. Coexisten varios modelos (francoalemán, híbrido y angloamericano), algunos simultáneamente, en los diferentes países.

Monitoria acadêmica no curso de medicina: o desenvolvimento de um ensino híbrido como estratégia para integrar o discente ingressante em tempos pós pandêmicos: um relato de experiência / Academic monitoring in the medical course: the development of a hybrid teaching as a strategy to integrate the entering student in post-pandemic times: an experience report / Seguimiento académico en la carrera de medicina: el desarrollo de una enseñanza híbrida como estrategia de integración del alumno de nuevo ingreso en tiempos post- pandémicos: relato de una experiencia

No período pós pandêmico o retorno às aulas se deu em modelos distintos, dentre eles, o híbrido, capaz de utilizar da melhor forma os recursos presentes, tanto na educação presencial, quanto na não-presencial. O presente trabalho é um relato de experiência com o objetivo de descrever a participação, como discente monitor, de três acadêmicos do curso de Medicina da Universidade Federal da Integração Latino- Americana no projeto "Monitoria Acadêmica em Programa de Integração Ensino Serviço Comunidade I como estratégia para integrar o estudante ingressante", relatando o uso de ferramentas digitais no ensino híbrido como método de superação das barreiras temporais e espaciais e de engajamento discente. Nesse sentido, evidenciou-se maior flexibilidade de acesso dos discentes ingressantes à monitoria acadêmica pela introdução do ensino híbrido, contribuindo para o processo de adaptação à vida acadêmica. Ainda, o uso de ferramentas digitais se mostrou um facilitador do processo de sistematização e internalização das informações e vivências. Por fim, o fator de maior relevância na integração dos discentes foi a promoção de ambientes abertos a questionamentos com coordenação horizontal e rede de apoio, sejam eles presenciais ou não.

In the post-pandemic period, the return to classes took place in different models, among them the hybrid model, capable of making the best use of the resources present in both face-to-face and non-presential education. The present work is an experi- ence report with the objective of describing the participation, as a student monitor, of three students from the Medicine course of the Federal University of Latin American Integration in the project "Academic Monitoring in the Program for Integration Teaching- Community Service I as a strategy to integrate the entering student", reporting the use of digital tools in hybrid teaching as a method to overcome temporal and spatial barriers and to engage the students. In this sense, there was evidence of greater flexibility of access of the incoming students to academic monitoring through the introduction of hybrid tea- ching, contributing to the process of adaptation to academic life. Still, the use of digital tools proved to be a facilitator of the process of systematization and internalization of information and experiences. Finally, the most relevant factor in the integration of stu- dents was the promotion of open environments with horizontal coordination and support network, whether face-to-face or not.

En el período post-pandémico, el regreso a clases se dio en diferentes mo- delos, entre ellos el híbrido, capaz de aprovechar al máximo los recursos presentes en la enseñanza presencial y no presencial. El presente trabajo es un relato de experiencia con el objetivo de describir la participación, como alumno monitor, de tres estudiantes del curso de Medicina de la Universidad Federal de Integración Latinoamericana en el pro- yecto "Seguimiento Académico en Programa de Integración Docente Servicio Comuni- tario I como estrategia de integración del alumno ingresante", dando cuenta del uso de herramientas digitales en la educación híbrida como método de superación de las barreras temporales y espaciales y de compromiso del alumno. En este sentido, se evidenció una mayor flexibilidad de acceso de los estudiantes al seguimiento académico por la introdu- cción de la enseñanza híbrida, contribuyendo al proceso de adaptación a la vida acadé- mica. Aún así, el uso de herramientas digitales demostró ser un facilitador del proceso de sistematización e internalización de información y experiencias. Finalmente, el factor más relevante en la integración de los estudiantes fue la promoción de ambientes abiertos al cuestionamiento con coordinación horizontal y red de apoyo, presencial o no.

Captadores solares de placa plana para el secado solar indirecto de alimentos: características y aplicaciones / Flat plate solar collectors for indirect type solar food drying: characteristics, and applications

Resumen La industria alimentaria utiliza hasta el 15 % del total de la energía eléctrica que demanda el sector industrial, principalmente en procesos de secado. Esto suscita la búsqueda de nuevas alternativas de secado que reduzcan el uso de energía eléctrica. Una opción es el secado solar, principalmente, el de tipo indirecto, a través de captadores solares de placa plana (CSPP). El objetivo de este trabajo fue analizar los recientes desarrollos de los CSPP, características, ventajas, desventajas, eficiencia y diversas tecnologías utilizadas en conjunto, para aumentar la eficiencia térmica en el secado solar. Los CSPP han desarrollado, a través de la hibridación con la utilización de otras fuentes de energía (eléctrica, biomasa, solar), un incremento en su eficiencia que los vuelve cada vez más viables para ser utilizados en procesos comerciales de secado de alimentos.

Abstract The food industry uses up to 15 % of the total electrical energy demanded by the industrial sector, mainly in drying processes. This motivates the search for new drying alternatives that reduce the use of electrical energy. One option is solar drying; mainly indirect type solar drying, that uses flat plate solar collectors (FPSC). The objective of this work was to analyze the recent developments of the FPSC, their characteristics, advantages, disadvantages, efficiency, and the range of technologies used in conjunction with the FPSC to increase their thermal efficiency for solar drying. The FPSC have developed through hybridization with the use of other energy sources (electricity, biomass, solar), an increase in their efficiency, that increasingly turns them into viable options for food drying processes.

Carcinoma escamoso híbrido de la planta del pie / Squamous hybrid carcinoma of the sole of the foot

Resumen El carcinoma escamoso (CEC) es un tumor maligno de la epidermis y sus anexos. Es el segundo en frecuencia después del carcinoma basocelular y presenta distintas variantes clinicopatológicas. El subtipo carcinoma verrucoso (CV) es una variante poco frecuente de CEC con características histopatológicas y comportamiento específico. Ocasionalmente, se pueden observar componentes carcinomatosos de células escamosas convencionales en el CV, denominándose a esta entidad tumores "híbridos", los cuales representan el 20% de los casos observados. Reportamos el caso de un paciente varón de 72 años con una gran lesión exofítica que compromete 5to dedo y planta de pie derecho con diagnóstico de carcinoma escamoso híbrido. El objetivo de la presentación es mostrar una asociación infrecuente, haciendo énfasis en su seguimiento cercano ya que puede manifestar cambios en su comportamiento clínico diseminándose a los ganglios linfáticos regionales.

Abstract Squamous carcinoma (SCC) is a malignant tumor of the epidermis and its appendages. It is the second most common after basal cell carcinoma and has different clinicopathological variants. The verrucous carcinoma (VC) subtype is a rare variant of SCC with histopathological characteristics and specific behavior. Occasionally, carcinomatous components of conventional squamous cells can be observed in the VC, this entity being called "hybridized" tumors, which represent 20% of cases.We report the case of a 72-year-old male with a large exophytic lesion involving the 5th right toe and foot with a diagnosis of squamous hybrid carcinoma. The objective of the presentation is to show an infrequent association, emphasizing its close follow-up as it can modify its clinical behavior by spreading to regional lymphnodes.

Controversias en la técnica de detección del ganglio centinela en cáncer de endometrio / Controversy over sentinel lymph node detection in endometrial cancer

En la última década se ha introducido la biopsia selectiva del ganglio centinela en cáncer de endometrio de bajo riesgo, siendo opcional en el de riesgo intermedio y alto. Sin embargo, hasta hace un año no se existía consenso respecto al grupo de población indicado, el trazador de elección o el lugar de administración del trazador. En este trabajo, presentamos de forma multidisciplinar los aspectos más controvertidos sobre la técnica de detección del ganglio centinela en cáncer de endometrio, con mayor énfasis en las ventajas y desventajas de los tipos de trazadores disponibles: radiotrazadores, trazadores híbridos y verde de indocianina (AU)

In the last decade, the procedure of sentinel lymph node biopsy has been introduced in low-risk endometrial cancer, being optional in intermediate- and high-risk cancer. However, until the last year, there was no consensus regarding the group of patients to whom to apply it, the best tracer to use or the site of injection. In this paper, we present in a multidisciplinary view the most controversial issues about the sentinel lymph node procedure in endometrial cancer, emphasizing the pros and cons of the different tracers available: radiotracers, hybrid tracers and indocyanine green (AU)

Nefrectomía parcial laparoscópica off-clamp tras la embolización del tumor en sala híbrida frente a nefrectomía parcial convencional: un análisis de pares emparejados por puntuación de propensión / Off-clamp laparoscopic partial nephrectomy in a hybrid room after tumor embolization versus conventional partial nephrectomy: A propensity score matched pair analysis

Objetivo: La nefrectomía parcial laparoscópica off-clamp tras la embolización arterial superselectiva (NPLh) en un quirófano híbrido es un abordaje mínimamente invasivo prometedor. En este estudio comparamos los resultados quirúrgicos perioperatorios de esta técnica innovadora con los de la técnica estándar de nefrectomía parcial laparoscópica convencional (NPLc).Pacientes y métodos: En total se incluyeron 86 y 127 pacientes tratados con NPLh y NPLc, respectivamente. Las dos técnicas se compararon en términos de complicaciones quirúrgicas, pérdida de sangre estimada (PSE), tiempo quirúrgico, duración de la estancia hospitalaria (DEH), márgenes quirúrgicos y tasa de consecución de la Trifecta (definida como duración de isquemia caliente <25min, márgenes quirúrgicos negativos y ausencia de complicaciones). Se utilizó una puntuación de propensión basada en la edad, el sexo, el índice de masa corporal (IMC), la tasa de filtración glomerular estimada (TFGe) preoperatoria y el tamaño tumoral para un emparejamiento 1:1 de los pacientes de cada grupo. Tras el emparejamiento, se obtuvieron dos grupos de 67 pacientes con características similares.Resultados: La tasa de conversión a cirugía abierta, las complicaciones y la PSE fueron similares entre ambos grupos. Por el contrario, el tiempo quirúrgico, la DEH y las tasas de Trifecta favorecieron la NPLh. El análisis multivariante demostró que la NPLh tenía un 70% más de probabilidades de lograr la Trifecta que la NPLc en todos los grupos de edad y para cualquier tamaño tumoral en toda la población del estudio.Conclusión: En comparación con el abordaje convencional, la nefrectomía parcial laparoscópica sin clampado después de la embolización arterial superselectiva en una sala híbrida mostró resultados quirúrgicos satisfactorios inmediatos y alcanzó una mayor tasa de consecución de la Trifecta. Se necesitan resultados funcionales y oncológicos a medio y a largo plazo para establecer esta

Objective: Off-clamp laparoscopic partial nephrectomy in a hybrid operating room after superselective arterial embolization (hLPN) is a promising minimally invasive approach. In this study, we compared the perioperative surgical outcomes of this innovative technique with the conventional standard of care laparoscopic partial nephrectomy (cLPN) technique.Patients and methods: Overall, 86 and 127 patients treated with hLPN and cLPN, respectively, were included. These two techniques were compared in terms of surgical complications, estimated blood loss (EBL), operative time, length of stay (LOS), surgical margins, and Trifecta achievement rate (defined as warm ischemia duration <25min, negative surgical margins and absence of complications). A propensity score based on age, gender, BMI, preoperative eGFR and tumor size was used for a 1:1 matching of patients of each group. After matching, two groups of 67 patients with similar characteristics were obtained.Results: Conversion rate to open surgery, complications and EBL were similar in both groups. Conversely, operative time, LOS and Trifecta rates favored hLPN. The multivariate analysis showed that hLPN had a 70% higher chance of Trifecta achievement than cLPN in all age groups and for all tumor size across the study population.Conclusion: Compared to a conventional approach, off-clamp laparoscopic partial nephrectomy in a hybrid room after superselective arterial embolization showed satisfying immediate surgical outcomes and reached a higher rate of Trifecta achievement. Mid and long-term functional and oncological results are needed to establish this minimally invasive surgical alternative (AU)

Eficacia clínica de los umbrales de intervención híbridos y dependientes de la edad basados en FRAX en la población ecuatoriana / Clinical efficacy of FRAX-based age-dependent and hybrid intervention thresholds in the Ecuadorian population

Objetivo: Evaluar el impacto clínico de los umbrales de intervención basados en FRAX en mujeres ecuatorianas. Probar una combinación de umbrales de intervención fijo y específico de la edad para optimizar la selección de mujeres elegibles para intervención.Pacientes y métodos: Estudio transversal. Se seleccionaron 2.283 mujeres de 60 a 94 años. Calculamos el riesgo de fracturas osteoporóticas principales y de cuello de fémur con el modelo FRAX ecuatoriano (versión 4.1), y calculamos la proporción de individuos elegibles para tratamiento y evaluación de la densidad mineral ósea aplicando los umbrales específicos de edad de 60 a 94 años y un umbral fijo a partir de 75 años.Resultados: Aplicando los umbrales específicos de la edad, 2% de las mujeres calificaron para tratamiento y 73,7% para evaluación de la densidad mineral ósea. Según la edad, las mujeres elegibles para tratamiento fluctuaron entre 0,7 a 3,8% y las elegibles para evaluación de la densidad mineral ósea entre 58,3 al 80,5%.Con el umbral fijo, 31% de las mujeres calificaron para tratamiento y 76,3% para evaluación de la densidad mineral ósea. Dependiendo de la edad, las mujeres potencialmente elegibles para tratamiento fluctuaron de 3,8 a 76,5%, y las elegibles para evaluación de la densidad mineral ósea entre 65,2 al 85,4%.Conclusiones: La proporción de mujeres potencialmente elegible para el tratamiento, es baja comparada con países con riesgo alto de fracturas. Utilizar un umbral fijo a partir de los 75 años, optimiza la proporción de mujeres elegibles para tratamiento. En los países con riesgo de fractura bajo a moderado, con recursos limitados, un modelo híbrido puede ser más adecuado. (AU)

Two-step treatment of a giant skull vault hemangioma: A rare case report and literature review / Tratamiento en dos pasos de un hemangioma de la bóveda craneal gigante: informe de un caso poco frecuente y revisión de la literatura

kull vault hemangiomas are benign vascular tumours of the calvaria that are usually asymptomatic or present as firm, painless lumps. We present a case of a 59-year-old female with a giant intraosseous calvarial hemangioma that was admitted in our department with a palpable mass over the left frontoparietal region, personality changes and impaired emotional and cognitive functions. The patient was treated with a two-step approach involving endovascular and surgical treatment, and suffered two rare, but recognized complications, a contrecoup intracerebral haemorrhage and valproate-induced stupor and parkinsonism.

Manejo híbrido del trauma de arco aórtico / Hybrid management of aortic arch trauma

El trauma aórtico es la segunda causa de muerte por trauma cerrado. Presentamos el caso de un paciente al que se le realizó un abordaje híbrido dadas las características, la localización y las particularidades anatómicas de la lesión, con excelentes resultados.Se trata de un paciente de 31 años que ingresó remitido con un cuadro de 15 días de evolución de un trauma contundente por la caída desde un parapente (desde 15 metros de altura). En la atención inicial se evidenció una fractura abierta del miembro inferior izquierdo manejada con tutor externo, hemotórax y neumotórax bilateral, manejados con toracostomía cerrada. Se tomaron imágenes según los protocolos de trauma, que evidenciaron lesión aórtica de grado III. Se decidió reparación híbrida: debranching desde la aorta ascendente hacia el tronco braquiocefálico y la arteria carótida común izquierda, con posterior reparación endovascular con endoprótesis aórtica para cobertura desde la zona cero a la zona cuatro de Ishimaru con sistema endovascular Zenith Cook dissection (Cook Medical Inc., Bloomington, Indiana, Estados Unidos). La evolución posterior fue satisfactoria y sin complicaciones.(AU)

Aortic trauma is the second cause of death due to blund trauma. We present a patient who underwent a hybrid approach given the characteristics, location, and anatomical characteristics of the lesion, with excellent results.A 31-year-old male patient was admitted with a 15-day of blunt trauma due to a fall from a paraglider (15 meters). Initial care revealed an open fracture of the left lower limb managed with an external tutor, hemothorax and bilateral pneumothorax, managed with a closed thoracostomy. Images were taken according to trauma protocols, showing grade III aortic injury. Hybrid repair was decided, debranching from the ascending aorta towards the brachiocephalic trunk and the left common carotid artery, with subsequent endovascular repair aortic endoprosthesis for coverage from zone zero to zone four of Ishimaru with Zenith Cook dissection endovascular system (cook Medical INC., Bloomington, In, USA), uncomplicated procedures.(AU)

RESUMO Objetivo descrever a incorporação da teleaudiologia na rotina de um programa público referência em implante coclear e avaliar a satisfação dos usuários e de seus familiares com a assistência híbrida. Métodos foram desenvolvidas ações que proporcionaram a conexão entre usuários e especialistas, por meio do modelo híbrido da teleaudiologia, combinando práticas remotas (síncronas/ assíncronas) e/ou atendimentos presenciais. Para verificar a satisfação dos pacientes com a teleaudiologia, foi aplicado o Questionário de Satisfação do Cliente. Resultados foram realizados 218 atendimentos remotos e 23 atendimentos presenciais coordenados, entre teleconsultas para orientação e aconselhamento, coaching de pais, terapia para reabilitação auditiva, validação dos resultados, resolução de problemas, ativação e mapeamentos, procedimentos intraoperatórios, teleconsultas com especialistas e entregas de peças de manutenção da tecnologia auditiva. Dos participantes, 36 responderam ao questionário, relataram estar muito satisfeitos com os serviços prestados de maneira geral, ou em grande parte (88,9%) e com a quantidade de atendimentos que receberam (72,2%). Este estudo sugeriu que, em algum momento durante a pandemia, a maioria dos pacientes teve suas necessidades atendidas usando teleaudiologia para cuidados continuados. Conclusão a abordagem de atendimento híbrida em audiologia foi viável, aceita e alcançou satisfação dos usuários.

ABSTRACT Purpose This article aims to describe the incorporation of teleaudiology in the routine of a highly regarded, government funded, cochlear implantation program and evaluate the satisfaction of users and their families with hybrid assistance. Methods Actions were developed that provided the connection between users and specialists, through the hybrid model of teleaudiology, combining remote practices (synchronous/asynchronous) with face-to-face care. To check patient satisfaction with teleaudiology, the Customer Satisfaction Questionnaire (CSQ) was applied. Results 218 remote appointments and 23 other presential attendances were coordinated, between teleconsultations, guidance and counseling; parent coaching and hearing rehabilitation validation, therapy; troubleshooting, cochlear implant first activations and mappings, intra-operative measures, teleconsultations with specialists and delivery of repaired electronic devices. Of the participants, 36 patients responded to the questionnaire and reported being very satisfied with the services provided in general or in large part (88.9%) and with the amount of care they received (72.2%).This study suggested that, at some point during the pandemic, most patients had their needs met using teleaudiology long term care. Conclusion The hybrid approach to audiology care was feasible, accepted and achieved user satisfaction.

Impact of adherence to the hybrid algorithm for initial crossing strategy selection in chronic total occlusion percutaneous coronary intervention.

INTRODUCTION AND OBJECTIVES: The hybrid algorithm was designed to assist with initial and subsequent crossing strategy selection in chronic total occlusion (CTO) percutaneous coronary interventions (PCIs). However, the success of the initially selected strategy has received limited study. METHODS: We examined the impact of adherence to the hybrid algorithm recommendation for initial CTO crossing technique selection in 4178 CTO PCIs from a large multicenter registry. RESULTS: The initial crossing strategy was concordant with the hybrid algorithm recommendation in 1833 interventions (44%). Patients in the concordant group had a similar age to those in the discordant group but a lower mean J-CTO score (2.0 ± 1.4 vs 2.8 ± 1.1; P < .01). The concordant group showed higher technical success with the first crossing strategy (68% vs 48%; P < .01) and higher overall technical success (88% vs 83%; P < .01) with no difference in the incidence of in-hospital major adverse events (1.8% vs 2.3%; P = .26). In multivariable analysis, after adjustment for age, prior myocardial infarction, prior PCI, prior coronary artery bypass grafting, J-CTO score, and scheduled CTO PCI, nonadherence to the hybrid algorithm was independently associated with lower technical success of the initial crossing strategy (odds ratio, 0.55; 95% confidence interval, 0.48-0.64; P < .01). CONCLUSIONS: Adherence to the hybrid algorithm for initial crossing strategy selection is associated with higher CTO PCI success but similar in-hospital major adverse cardiac events.

Coffea canephora breeding: estimated and achieved gains from selection in the Western Amazon, Brazil / Melhoramento do Coffea canephora: ganhos de seleção estimados e realizados na Amazônia Ocidental

ABSTRACT: Gain from selection is an important criterion in quantifying the efficiency of breeding programs. This study quantified the selection gain estimated under experimental conditions and realized gain achieved in the field, seeking to interpret the efficiency of the Coffea canephora selection. For that purpose, we considered experiments that began in 2004 with directed hybridizations to obtain new hybrid progenies. From a breeding population composed of 288 hybrid individuals, 12 genotypes were selected in experimental conditions from 2005 to 2012, with amplitude in the estimated gains from 127.70 to−19.19%. Those genotypes were evaluated from 2012 to 2018 in clonal tests in four environments of the Western Amazon. The environment that exhibited the greatest correlation between the predicted genetic values and the realized genetic gain observed in the field was the environment of Ouro Preto do Oeste, RO (0.67), the location in which the plants were selected, followed by the environments of Alta FlorestaD´Oeste, RO (0.44), Rio Branco, AC (0.43), and Porto Velho, RO (0.37).Experimental conditions showed that the effect due to dominance deviations was approximately three times greater than the additive effect. Nine clones exhibited higher genetic gains in the experimental conditions and at field, and two clones exhibited lower estimated gains and lower field performance.The clone G17-P7 exhibited high genetic gain under experimental conditions and low field performance. The selection in experimental conditions was positively correlated with plant performance in the field (r=0.55), which allows reduction of the original breeding population to a set of more promising clones to be grown in multiple environments, optimizing time and resources.

RESUMO: O ganho com a seleção é um dos critérios mais importantes para avaliar a eficiência de programas de melhoramento de plantas. O objetivo desse trabalho é quantificar a associação entre o ganho de seleção estimado em condições experimentais e o ganho de seleção realizado em campo, buscando quantificar a eficiência do melhoramento do Coffea canephora. Para isso, foram considerados experimentos iniciados com a hibridação direcionada para obtenção de progênies no ano de 2004, a avaliação de testes de progênies em condições experimentais no período de 2005 a 2012, e avaliações em diferentes ambientes da Amazônia Ocidental no período de 2012 a 2018. De uma população composta por 288 indivíduos estruturados em nove progênies de irmãos completos foram selecionados 12 genótipos com amplitude de 127,70 a -19,19% em suas estimativas de ganho com a seleção, para serem avaliados em quatro ambientes da Amazônia Ocidental. O ambiente que apresentou maior correlação entre os valores genéticos preditos e o ganho realizado foi Ouro Preto do Oeste - RO (0,67), local em que as plantas foram selecionadas, seguido pelos ambientes de Alta Floresta D´Oeste - RO (0,44), Rio Branco - AC (0,43) e Porto Velho - RO (0,37). Avaliações em condições experimentais mostraram que os efeitos devido aos desvios de dominância foram aproximadamente três vezes maiores do que os efeitos aditivos. Nove clones apresentaram maiores estimativas de ganho em condições experimentais e nos ensaios de campo, e dois clones apresentaram menores estimativas em ambas condições. O clone G17-P7 apresentou altas estimativas de ganho em condições experimentais e baixo desempenho em campo. A seleção em único ambiente esteve positivamente correlacionada com o desempenho dos cafeeiros em campo (r=0,55), permitindo reduzir a população de melhoramento original em um conjunto de clones de maior potencial agronômico.

Mudanças e adaptações das universidades comunitárias em tempos de crise / Changes and adaptations of community universities in times of crisis

Na entrevista, o professor Vilmar Thomé considera sua trajetória acadêmica e profissional, em especial sua experiência de Pró-Reitor e de Reitor na Universidade de Santa Cruz do Sul (UNISC), para analisar as mudanças e as adaptações que ocorrem nas Universidades Comunitárias num momento em que o ensino universitário no Brasil é provocado a se reinventar. Para o professor Thomé, vivemos um momento em que os diferentes modelos de Universidade no Brasil precisam ser repensados, considerando a importância de melhorar o aproveitamento dos recursos investidos, de alcançar melhores resultados, de ter maior capacidade de atender às necessidades da sociedade. Na experiência das Universidades Comunitárias, o professor destaca três questões que se consolidaram como legado da história até então construída: transparência, descentralização e participação. Mas destaca que o momento é de adaptações, sem esquecer o legado construído, mas considerando os desafios de um tempo de crise e de transformações tecnológicas que criam novas possibilidades de organização das atividades universitárias.(AU)

In the interview, Professor Vilmar Thomé considers his academic and professional trajectory, especially his experience as Pro-Rector and Rector at the University of Santa Cruz do Sul (UNISC), to analyze the changes and adaptations that occur in Community Universities at a time in which university education in Brazil is provoked to reinvent itself. For Professor Thomé, we live in a moment in which the different models of University in Brazil need to be rethought, considering the importance of improving the use of invested resources, of achieving better results, of having a greater capacity to meet the needs of society. In the experience of Community Universities, the professor highlights three issues that have consolidated themselves as a legacy of the history built up to then: transparency, decentralization and participation. But he highlights that the moment is one of adaptations, without forgetting the legacy built, but considering the challenges of a time of crisis and technological changes that create new possibilities for organizing university activities.(AU)
