ABSTRACT. The genus Leocrates is currently made up of 11 nominal species, of which Leocrates chinensisKinberg, 1866 is the type species. Kinberg's original description is brief, and the diagnostic morphological characters are poorly defined. Therefore, numerous subsequent records in different world regions have been considered doubtful. Numerous specimens of Leocrates collected by SCUBA diving in various locations of Robinson Crusoe Island (33°37′S, 78°51′W) in the Juan Fernández Archipelago, between 4 and 10 m depth were examined and determined as a new species herein named Leocrates ernstehlersi n. sp. It is characterized by the size of anterior and posterior eyes, the median chaetigers with scarce notochaetae and neurochaetae per bundle; neurochaetal blades are 4-14 times longer than wide and neuracicular lobes slightly longer than wide. A key to identifying species of Leocrates having large anterior eyes and anterior eyes/prostomial width ratio between 1/4 to 1/8 is also included.

RESUMEN Objetivo: Describir la prevalencia de la disfunción sexual en un grupo de mujeres gestantes y hacer una exploración de posibles factores asociados a la disfunción sexual en estas mujeres. Materiales y métodos: Estudio descriptivo y trasversal en mujeres gestantes cuyas edades son de 15 años o más, con actividad sexual en la gestación, que asistieron al control prenatal en el Hospital San Juan de Dios de Rionegro entre los meses de enero y marzo del 2021. Se excluyeron pacientes con limitaciones o discapacidad cognitiva, o clasificadas con trastorno mental según la Organización Mundial de la Salud (OMS), gestantes con patologías crónicas, placentarias, ovulares, hemorrágicas e infecciosas, y las pacientes cuya gestación fue resultado de violencia sexual. Se aplicó el cuestionario Índice de Función Sexual Femenina (FSFI), se midieron variables sociodemográficas y de salud sexual y reproductiva. Los resultados se expresan en frecuencias absolutas y relativas para las variables cualitativas y medianas, y rangos intercuartílicos para las variables cuantitativas. Resultados: La mediana de edad fue de 27,5 años (RIC: 21,3-31,0); de edad gestacional 28,5 semanas (RIC: 21,3-34,8). Tras la aplicación del FSFI, 37 mujeres (37,7%) tuvieron disfunción sexual (puntaje < 26,5). La mediana del puntaje de las participantes sin disfunción sexual fue de 29,4 (RIC 26,8-32), mientras que por el lado de las que tienen disfunción sexual fue de 22,3 (RIC 20-24). La media del puntaje para cada dominio fue: deseo: 3,6 (RIC: 3,0-4,2); excitación: 4,5 (RIC: 3,6-5,1); lubricación: 4,8 (RIC: 3,9-5,4); orgasmo: 4,4 (RIC: 3,6-5,2); dolor: 4,4 (RIC: 3,6-6,0); y satisfacción: 5,4 (RIC: 4,8-6,0). Fueron factores protectores no tener hijos ni cesáreas previas. La ausencia de compañero y menor edad estuvieron asociados a disfunción sexual. Conclusión: La disfunción sexual se presenta en por lo menos un tercio de las gestantes, especialmente en el tercer trimestre. En la práctica clínica diaria se hace necesario abordar la disfunción sexual, ya que se puede contribuir desde el abordaje de la educación a un problema que puede afectar las relaciones de pareja y la calidad de vida. Es fundamental generar nuevas investigaciones que incluyan la evaluación de la efectividad y seguridad de estrategias educativas en este grupo poblacional con disfunción sexual.

ABSTRACT Objective: To describe the prevalence of sexual dysfunction in a group of pregnant women, and to explore potential factors associated with this condition in this population. Material and methods: Descriptive cross-sectional study in pregnant women 15 years of age and older, sexually active during gestation, receiving prenatal care at the San Juan de Dios Hospital in Rionegro between January and March, 2021. The exclusion criteria were patients with disabilities or cognitive impairment, or classified as having a mental disorder according to the World Health Organization (WHO); pregnant women with chronic, placental, ovulation, hemorrhagic or infectious conditions; and patients whose pregnancy was the result of sexual assault. The Female Sexual Function Index (FSFI) questionnaire was applied, and sociodemographic and sexual and reproductive health variables were measured. Results are expressed as absolute and relative frequencies for qualitative variables, and as medians and interquartile ranges for quantitative variables. Results: The mean age in years was 27.5 (IQR: 21.331.0) and the mean gestational age was 28.5 weeks (IQR: 21.3-34.8). After administering the FSFI, it was found that 37 women (37.7%) had sexual dysfunction (score < 26.5). The median scores for the participants without sexual dysfunction and those with sexual dysfunction were 29.4 (IQR 26.8-32) and 22.3 (IQR 20-24), respectively. The mean scores for each domain were: desire 3.6 (IQR: 3.0-4.2); arousal 4.5 (IQR: 3.65.1); lubrication 4.8 (IQR: 3.9-5.4); orgasm 4.4 (IQR: 3.6-5.2); pain 4.4 (IQR: 3.6-6.0); and satisfaction 5.4 (IQR: 4.8-6.0). The total score (p<0.05) was better in older women and those with one or more children. Conclusion: Sexual dysfunction occurs at least in one-third of pregnant women, especially during the third trimester. Sexual dysfunction should be considered in daily clinical practice, given that approaching the topic from an education perspective can help reduce a problem that affects the couple and quality of life. It is critical to undertake additional research that includes assessment of the effectiveness and safety of educational strategies in this population with sexual dysfunction.

ABSTRACT The fight towards equality for LGBTI groups in the country has made a lot of progress in the past few years. However, a brief overview to the current legal framework, including public policies within the criminal justice system and the rehabilitation system, persuades to believe that what has been achieved so far, has longed overlooked a differential and fair treatment within prisons. Likewise, academic research about transgender people inside the prison system are scarce, and for the Ecuadorian case, it can be argued are almost inexistent. It is a realm that has escaped the government’s view. Gender identity and respect towards individual sexuality have been actively promoted from the OC-24/17, which also reflects itself to the criminological context into the prison system in Ecuador. This essay will try to confront this reality and make some space to debate.

RESUMEN La lucha por la igualdad de derechos para con grupos LGBTI en el país ha dado importantes pasos en los últimos años. Sin embargo, un análisis superficial tanto de la normativa vigente, así como de las políticas públicas dentro del sistema penal y de rehabilitación de penas, induce a creer que los avances logrados han dejado de largo un tratamiento justo y diferenciado acorde a las distintas necesidades individuales dentro de las cárceles en el país. De la misma manera, los estudios académicos sobre personas transgénero dentro del sistema penitenciario son escasos, y para el caso ecuatoriano casi inexistente, realidad que escapa incluso a los entes gubernamentales. El respeto a la identidad de género y sexual promovida desde la OC-24/17 se decanta al contexto criminológico visto desde el sistema de rehabilitación de penas en Ecuador. Este ensayo intentará enfrentar dicha problemática y abrir espacio a la discusión.

ABSTRACT: The conditions of natural hazards and exposure of economic activities in a norpatagonic fjord, an extreme territory in continental Chiloé, was analyzed due to the lack of terrestrial communication routes. Although the population is scarce, not the economic activities linked to aquaculture. The State of Chile has planned to build an Austral Route (Route CH-on the eastern slope of the fjord In this scenario, the natural hazard are analyzed and also how will be potentially affected the land. Methodologically, geomorphological work and GIS geoinformation processing were carried out to establish the hazard; these were superimposed on land and water uses. The result expresseed a territory with multi-haz-ards and a high exposure of current and projected economic activities, enhanced by the influence of the Austral highway.

RESUMEN: Se analizan las condiciones de amenazas de origen natural y de exposición de las actividades económicas en un fiordo norpatagónico, de Chiloé continental. Se considera como un territorio extremo debido a la inexistencia actual de vías de comunicación terrestres. Si bien el poblamiento es escaso, no así las actividades económicas vinculadas a la acuicultura. El Estado de Chile ha planificado construir un tramo de la carretera austral en la vertiente oriental del fiordo (Ruta CH-7). En este escenario, se analizan las amenazas de origen natural y cómo éstas afectan los territorios con aptitud productiva y la carretera austral proyectada. Metodológicamente se realizó trabajo geomorfológico y procesamiento de geoinformacion SIG para establecer las amenazas; éstas fueron superpuestas con los usos del suelo y del agua. El resultado expresa un territorio con multiamenazas y con una alta exposición de las actividades económicas actuales y proyectadas, potenciado por la influencia de la carretera Austral.

Resumen: Se identificaron y caracterizaron los poliquetos bentónicos de los órdenes Amphinomida, Phyllodocida y Eunicida, recolectados en la región de fiordos y canales australes de Chile, en la provincia biogeográfica Magallánica (420S-5ó°S), desde el estero Reloncaví (41 ° 25 ’ S) hasta el estero Obstrucción (52°11’S), entre 26 y 1173 metros de profundidad, durante los cruceros de investigación CIMAR 13, 14, 15, 17, 18 y 20 Fiordos, entre los años 2007 y 2014 (CIMAR; Cruceros de Investigación Marina en Áreas Remotas). Se analizaron 117 estaciones oceanográficas, distribuidas en cada uno de los cruceros ordenados geográficamente de norte a sur de la siguiente manera: CIMAR 17, 24 estaciones, desde estero Reloncav (41°40’S, 72°24’O) a boca del Guafo (43°49’S, 74°23’O); CIMAR 13, 25 estaciones, desde boca del Guafo (43°46,40’S) a estero Elefantes (46°29,00’S); CIMAR 18, 16 estaciones, desde boca del Guafo (43°46,40’S) a estero Elefantes (46°29,00’S, 73°49,00’O); CIMAR 20, 26 estaciones, desde golfo de Penas a canal Trinidad; CIMAR 14, 15 estaciones, entre golfo de Penas y canal Trinidad (47°S a 50°10’O) y CIMAR 15, 11 estaciones, desde seno Europa (50°07,00’S, 74°14,20’O) a estero Obstrucción (52°11,00’S, 72°32,20’O). Las muestras se obtuvieron a bordo de los buques de investigación oceanográfica AGOR 60 “Vidal Gormaz”, en los cruceros CIMAR 13, 14 y 15 Fiordos, B/I “Abate Molina”, en los cruceros CIMAR 17 y 18 Fiordos y AGS 61 “Cabo de Hornos” en el crucero CIMAR 20 Fiordos. En toda el área se registraron 15 familias y 39 especies de poliquetos de los tres órdenes considerados. Las tres familias con más especies registradas fueron Polynoidae (nueve especies), Nereididae (cinco especies) y Lumbrineridae (cinco especies). De las especies recolectadas, siete constituyen nuevos registros para la zona de estudio y tres son nuevos registros para Chile.

Flat sintered copper and copper-zirconia substrates, with zirconia nanoparticles contents of 1 and 3 vol%, were produced by aqueous tape casting and controlled sintering. Aqueous suspensions were prepared to a solid content of 58 vol% using 3 wt% commercial binder emulsion. The green tapes were treated at 350 ºC in air to remove organics and sintered at temperatures ranging from 800 to 1000 ºC in atmosphere of Ar/5%H2. Copper tapes reached almost full densification at 900 ºC. Composite with 1 vol% zirconia, sintered at 800 ºC, maintained high density and provided a noticeable increase of the mechanical strength, whereas further additions up to 3 vol% reduced the densification and the resulting mechanical performance became poorer.

In this work, nanometric Al2O3 (1-5 vol.%) particles (13 nm, 100 m2/g) were added to a 19.58Li2O•11.10ZrO2•69.32SiO2 (mol%) (3.5 µm, 2.5 m2/g) parent glass-ceramic matrix to prepare composites with the purpose of studying the influence of Al2O3 on their structure, microstructure, mechanical, thermal and electrical properties when sintered by fast firing. The parent glass-ceramic was prepared by melting and fast cooling (in water) to obtain a glass frit. The resulting glass frit was milled according to a two-step procedure consisting on a dry milling stage followed by a long wet milling step down. Each composition was wet homogenized and then dried at 110 ºC for 48 h for disaggregation. The obtained powders were uniaxially pressed (100 MPa) and compacts sintered by fast firing (175 ºC/min) between 800 and 900 ºC for 30 min. The composites, with relative densities ranging from 89% to 93%, showed zircon and β-spodumene as main crystalline phases. The hardness and Young's modulus varied from 4.5 to 6.5 GPa, and from 65 to 102 GPa, respectively. The formation of β-spodumene in the obtained composites leads to reduce the CTEs, whose values ranged from 13 to 7 x 10-6 ºC-1.

RESUMO O processamento coloidal é uma técnica amplamente usada para a produção de componentes cerâmicos. Diversos artigos científicos foram publicados na última década apresentando a possibilidade de se obter suspensões aquosas concentradas estáveis de partículas metálicas a partir do seu controle de pH e uso de dispersantes. Este artigo tem o objetivo de estudar a produção de um aço com microestrutura austenítica usando pós elementares de ferro (Fe) e níquel (Ni) via rota coloidal. Para tanto, foram realizadas medições de potencial zeta entre os pHs 2 e 12 para a composição Fe30Ni em massa. As suspensões aquosas atingiram concentrações de sólidos de até 45% v/v e processadas por colagem de barbotina. Os compactados colados foram caracterizados por densidade (Arquimedes), análise térmica diferencial (ATD) e dilatometria. Após a sinterização aos 900°C e 1100°C/1h, os compactados apresentaram microestrutura com formação de maclas de recozimento, porosidade inferior a 10% em volume e microdureza Vickers aproximada de 160 HV.

ABSTRACT Colloidal processing is a widely used technique to produce ceramic components. Several papers have been published in the last decade presenting the possibility to obtain aqueous concentrate stable suspension of metallic particles from their pH control and using dispersants. This paper aims to study the production of a steel with austenitic microstructure using elemental iron (Fe) and nickel (Ni) powders via colloidal route. For this, Zeta potential measurements were performed between pH 2 and 12 to Fe30Ni wt% composition. Aqueous suspensions reached solids concentrations of up to 45% v/v and processed by slip casting. The compacts were characterized by density (Archimedes), differential thermal analysis (DTA) and dilatometry. After sintering at 900°C to 1100°C/1h, the sintered bodies presented a microstructure with of annealing twins, porosity less than 10 %v/v approximate Vickers microhardness of 160 HV.

In this work carbon steel plates were dip-coated with a composite film obtained from a colloidal suspension of Ni-TiO2. Suspensions with different solids contents were used to evaluate the adherence of the film and the microstructural features. The samples were characterized using both optical and scanning electron microscopy, energy dispersive spectroscopy and microhardness. The microstructural analysis revealed that the films have high porosity at the surface. However, an interfacial region was observed demonstrating that there was good adhesion between both materials. This region shows an increased hardness that can be attributed to diffusion mechanism of nickel from the composite film to the steel matrix. Besides the interface, there was an abnormal grain growth, followed by a region of smaller grains of austenite and at longer distances near the center of the plate some colonies of pearlite appear.

La instalación del bacilo de Calmette-Guérin es un tratamiento seguro y eficaz para el cáncer superficial de vejiga. La aparición de artritis tras su administración es un raro efecto secundario. Presentamos el caso clínico de un varón de 65 años que desarrolló oligoartritis asimétrica después de la sexta instalación del bacilo de Calmette-Guérin, que fue resuelta tras el cese del tratamiento y la administración de antiinflamatorios no esteroideos.

Intravesical instillation of Calmette-Guérin bacillus (BCG) is an effective and safe treatment for superficial bladder cancer. The reactive arthritis is a rare osteoarticular side-effect following intravesical BCG immunotherapy. The case is presented of a 65-year-old male, who developed reactive asymmetric oligoarthritis after the sixth BCG instillation, which was resolved with administration of non-steroidal anti-inflammatory drugs and discontinuation of intravesical instillation.

La espondilodiscitis por Streptococcus agalactiae es infrecuente, ya que éste es un microrganismo clásicamente patógeno en el periodo gestacional y perinatal. Sin embargo se está produciendo un aumento en la incidencia de infecciones invasivas en adultos inmunocompetentes. Asimismo, el síndrome de Parsonage-Turner o neuritis braquial aguda es una entidad clínica poco frecuente, caracterizada por dolor y debilidad muscular de la extremidad superior. Presentamos el caso de un varón de 50 años con bacteriemia por S. agalactiae, espondilodiscitis cervical y neuritis braquial secundaria y revisamos la literatura.

Spondylodiscitis caused by streptococcus agalactiae has been traditionally considered an infrequent disease since S. agalactiae is a pathogenic microorganism conventionally in gestational and perinatal period. However it is producing an increase in the incidence of invasive infections in immunocompetent adults. Also Parsonage-Turner syndrome or brachial radiculitis is a rare disorder and is characterized by pain followed by weakness in the distribution of the upper brachial plexus. We report one case and review the literature.

Background: Formative evaluation is a range of formal assessment employed by professors during the teaching process in order to modify curriculum activities, to improve student attainment. For students, it is helpful to evaluate their learning process. Although recommended, it is seldom used. Aim: To evaluate the perception and performance of medical students subjected to formative assessments during an integrative clinical course. Material and Methods: Fourth year medical students that participated in a multiple choice formative assessment, similar to the final exam during 2007 and 2008, responded a survey about the usefulness and quality of such assessment. Student achievement was expressed as the percentage of correct answers of the tests. Results: The formative assessment was answered by 99% of students. In 2007 97% of students considered the experience as excellent or very good and 92% evaluated it as useful or very useful. During 2008 the figures were 89% and 79%. The students outlined that this assessment oriented their study, allowed them to discover their weaknesses and have a perception of the degree of difficulty of the final exam. Over 90% of students that took the formative evaluation, improved their academic achievement. Conclusions: Formative assessments are well evaluated by medical students and improve their academic achievement.

El conformado neto de materiales cerámicos es una etapa fundamental del procesamiento, ya que en ella se convierte una masa de polvos en una pieza con la geometría y tamaño deseados. Durante la consolidación de la pieza se pueden introducir muchos defectos, por lo que el control de cada etapa para evitar o reducir la presencia de defectos es esencial. Entre las técnicas de conformado más interesantes para el conformado de piezas complejas destacan los métodos de gelificación de polisacáridos, debido a la relativa sencillez del método, el empleo de agua como medio de dispersión y la baja concentración de aditivos necesaria para obtener la pieza. En este trabajo se revisan las aplicaciones más importantes de los polisacáridos en el conformado de materiales cerámicos por técnicas de gelificación. Se describe la estructura química de los polisacáridos más comunes y los mecanismos de gelificación, tanto para aquellos que gelifican por polimerización química, como ocurre con los alginatos en presencia de iones divalentes, así como aquellos que gelifican por un cambio de temperatura, bien por calentamiento, como las celulosas, o por enfriamiento, como en el caso de agares y carragenatos. También se analiza la influencia de otros polisacáridos, empleados por sus propiedades como espesante, pero que presentan efecto sinérgico con polisacáridos gelificantes, como son las gomas de garrofín o de xantana. Junto a la estructura y los mecanismos básicos de gelificación, se muestran diversos ejemplos de la influencia de los polisacáridos en la reología de suspensiones cerámicas y en su conformado.

Near-net shaping of ceramics is a key step in ceramic processing, because in this step a mass of powder is transformed into a piece with the desired geometry and size. During consolidation many defects can be introduced in the piece, so that the control of any stage is necessary to reduce or avoid the presence of defects. The gelation of polysaccharides constitutes one the most interesting consolidation mechanisms for shaping of ceramics due to the relative simplicity of the method, the use of water as liquid medium and the low concentration of additives necessary to obtain the bodies. In this work the main applications of polysaccharides in ceramic manufacturing through a gelation mechanism are reviewed. The chemical structure of the most common polysaccharides and their gelation mechanisms are described, including those yielding chemical gelation, as in the case of alginates in the presence of divalent ions, as well as polysaccharides that gel by a temperature change, either on heating as in cellulose derivatives, or on cooling, as in the case of agar derivatives and carrageenans. The influence of other polysaccharides used for their thickening properties but having an important synergy with gelling polysaccharides is also analyzed. In addition to the structure and the basic gelation mechanisms, several examples showing the influence of polysaccharides on the rheology and shaping of ceramic slurries are presented.

The Acute Myocardial Infarctio (AMI) is the entity that produces the greatest morbidity in our society. It affects the quality of life of the patient and their Employment Status, responsible for a high percentage of Permanent Disabilities. And also among the major causes of temporary disability. Data Return to work after an AMI, vary widely from country to country. And from one Autonomous Community to another in our country. They have experienced great technological advances in the field of percutaneous coronary intervention (PTCA) and Stent placement vascular (STENT). And Cardiac control of cardiovascular risk factors, physical training programs, psychological intervention, educational and socio-assessment have facilitated the functional recovery of patients with improvements in cardiac and functional capacity of patients with better insight and quality of life, allowing them to return to their previous suffering acute coronary event, including labor activities functionality. In a program of performances and joint collaboration between the Medical Unit of the Provincial Directorate of Sevilla INSS and Unit Cardiac Rehabilitation and Secondary Prevention of Hospital Virgen Macarena in Seville, we propose to monitor the patients undergoing these programs Cardiac Rehabilitation in 2011 with a view to the possibility of their return to work. In our study we have shown that patients who follow a Multidisciplinary Cardiac Rehabilitation Program, get improvement in the variables listed above, with improvement in their functionality cardiac (84,3%) and feeling of Physical fitness and perceived quality of life (74%). Being labor subsidiary indication reinstatement 63% of patients included in our study.

El Infarto Agudo de Miocardio (IAM) es la Entidad que produce mayor morbimortalidad en nuestra Sociedad. Afecta a la Calidad de vida del Paciente y a su Situación Laboral, siendo responsable de un alto porcentaje de Incapacidades Permanentes. Así como también se encuentran entre las principales Causas de Incapacidad Temporal. Los datos de Reincorporación laboral tras un IAM varían mucho de unos Países a otros. Así como de unas Comunidades Autónomas a otras en nuestro país. Se han experimentado grandes Avances Tecnológicos en el campo del Intervencionismo Coronario Percutáneo (ACTP) y la colocación de Endoprótesis Vasculares (STENT). Así como los Programas de Rehabilitación Cardiaca y Prevención Secundaria, con actuaciones en el campo del control de los factores de riesgo cardiovascular, Programas de Entrenamiento físico, intervención psicológica, programas educativos y de valoración sociolaboral han facilitado la Recuperación funcional de los pacientes que han sufrido un IAM con mejoras en la funcionalidad cardiaca y en la capacidad funcional de los pacientes con mejor percepción y calidad de vida, que les permite la reincorporación a sus actividades anteriores a sufrir el evento coronario agudo, entre ellas la laboral. En un Programa de Actuaciones y de Colaboración conjunta entre la Unidad Médica de la Dirección Provincial de Sevilla del INSS y la Unidad de Rehabilitación Cardiaca y Prevención Secundaria del Hospital Universitario Virgen Macarena de Sevilla, nos planteamos hacer un seguimiento de los pacientes que realizaron estos Programas de Rehabilitación Cardiaca en el año 2011 con vistas a la posibilidad de su Reincorporación laboral. En nuestro estudio hemos demostrado que los Pacientes que siguen un Programa Multidisciplinar de Rehabilitación Cardiaca, consiguen mejoría en los variables que hemos analizado, con mejoría de su Funcionalidad Cardiaca (84,3%) y sensación de Bienestar Físico y Calidad de vida percibida (74%). Siendo subsidiarios de indicación de Reincorporación Laboral el 63% de los pacientes incluidos en nuestro Estudio.

In this study, the influence of mechanical activation by intensive ball milling of a stoichiometric mixture of talc, kaolin, and alumina on the mechanism and kinetics of cordierite (2MgO·2Al2O3·5SiO2) formation was evaluated. The raw materials were characterized by chemical analysis, X-ray diffraction (XRD), laser diffraction, and helium pycnometry. The kinetics and mechanism of cordierite formation were studied by XRD, differential thermal analysis, and dilatometry in order to describe the phase formation as a function of temperature (1000-1400 ºC), time of thermochemical treatment (0-4 h), and grinding time of the mixture (0-45 min). Finally, the optimal conditions of the thermochemical treatment that ensured the formation of cordierite were determined: milling time of 45 min and thermal treatment at 1280 ºC for 1 h.
