Oral communication abstracts obstetrical ultrasound for patients in underserved rural and remote communities where this service is not available. The objective of this study is to assess the feasibility of providing obstetrical ultrasound services remotely using a telerobotic ultrasound system in a remote community isolated due to COVID-19. Methods: A telerobotic ultrasound system was used to remotely perform obstetrical ultrasound exams in La Loche, Canada, a remote community without regular access to obstetrical ultrasound. Using a telerobotic ultrasound system, a sonographer 605km away remotely controlled an ultrasound probe and ultrasound settings. 21 exams were performed in a 5-week period during a COVID-19 outbreak, including limited first, second and third trimester exams (n = 11) and complete second trimester exams (n = 10). Radiologists interpreted all exams and determined adequacy of images for diagnosis. Results: Of 11 limited obstetrical exams, radiologists indicated images were adequate in 9 (81%) cases, adequate with some reservations in 1 (9%) case and inadequate in 1 (9%) case. Of 10 second trimester complete obstetrical exams, radiologists indicated images were adequate in 2 (20%) cases, adequate with some reservations in 3 (30%) cases and inadequate in 5 (50%) cases. Second trimester complete obstetrical exams were limited due to a combination of body habitus, fetal lie and telerobotic technology. Conclusions: A telerobotic ultrasound system may be used to answer focused clinical questions such as fetal viability and fetal presentation in a timely manner while minimising patient travel to larger centres and potential exposure to SARS-CoV-2 during the COVID-19 pandemic. The COVID-19 pandemic may catalyse the implementation of telerobotic sonography to bring greater accessibility and equity in the delivery of obstetrical ultrasound to patients in rural and remote communities.
Actualmente los eubióticos se postulan como una alternativa potencial de reemplazo a los antibióticos utilizados como subterapéuticos, a modo de promotores de crecimiento. Aunque múltiples estudios han demostrado el efecto benéfico de los eubióticos en los parámetros productivos y alométricos del pollo de engorde, el uso combinado de estos ha sido poco evaluado, sin conocerse su efecto sinérgico. El objetivo del presente estudio fue evaluar el efecto del uso sinérgico de eubióticos sobre los parámetros productivos y alométricos en pollos de engorde de la línea Ross AP. El estudio se realizó durante el año 2020 en una granja experimental del municipio de Piedecuesta, Santander, a una altura de 1005 msnm. Un total de 1400 animales fueron analizados mediante un diseño completamente al azar, evaluando siete tratamientos T1 = dieta base (DB), T2 = DB + antibiótico promotor de crecimiento (APC), T3 = DB + extracto natural (EN) + probiótico (Pro) + prebiótico (Pre), T4 = DB + EN + Pro + ácido graso de cadena media (AGCM), T5 = DB + Pre + Pro + AGCM, T6 = DB + EN + Pre + AGCM y T7 = DB + Pre + Pro + AGCM); con ocho repeticiones de 25 animales por cada tratamiento. Los parámetros productivos fueron evaluados al día 7, 14, 21, 28 y 35, mientras que los alométricos específicamente al día 35. Adicionalmente, un análisis de productividad económica fue realizado teniendo en cuenta los valores comerciales reportados al cierre del año 2020. En general se observaron diferencias significativas (P<0.05) en los siguientes parámetros productivos: peso promedio por ave al día 7, 14, 21, 28 y 35; consumo total por corral al día 14, 21 y 28; consumo acumulado por ave al día 21, 28 y 35; consumo promedio por ave al día 21, 28 y 35; conversión ajustada por mortalidad al día 21, 28 y 35; VPI al día 7, 21, y 28 e IEE, con los mejores valores en los tratamientos 3, 5, 6 y 7. Respecto a los parámetros alométricos, se observaron diferencias significativas (P<0.05) en los siguientes ítems: peso ave con vísceras y con plumas, peso ave sin vísceras y sin plumas, peso pechuga, peso alas, peso costillar y peso tarsos. La mayor productividad económica se obtuvo en los tratamientos 6 y 7, comparado con el tratamiento 1, respectivamente. En conclusión, se determinó que los mejores parámetros productivos y alométricos se presentaron en los animales que consumieron los tratamientos que contenían Manano-oligosacárido (MOS) como prebiótico en su formulación, por tal motivo la adición de estos compuestos, deben considerarse como alternativa nutricional inocua para mejorar el efecto sinérgico con otros eubióticos, e incrementar la eficiencia de los sistemas productivos.
Objectives: Gestational diabetes mellitus (GDM) is defined as impaired glucose tolerance with onset or first recognition during pregnancy, which is characterised by an increased insulin resistance. Myo-inositol has been suggested to improve insulin resistance in women with polycystic ovary syndrome (PCOS). The aim of this study is to examine if myo-inositol supplementation during pregnancy can reduce the incidence of gestational diabetes mellitus or at least the incidence of GDM related morbidity. Methods: This is a single-centre, open-labelled, randomised controlled trial. The study aims to enroll 160 healthy pregnant women over a two-year period. Participants are randomised at 11-13 +6 weeks of gestation, using a 1:1 ratio, to receive either myo-inositol and folic acid (4,000mg myo-inositol and 400mcg folic acid daily) or folic acid alone (400mcg folic acid daily). Treatment is discontinued at 26-28 weeks of gestation and a 2-hour 75g oral glucose tolerance test (OGTT) is offered for the diagnosis of gestational diabetes. Results: 33 patients have been enrolled until now of whom 19 received treatment with myo-inositol and folic acid and 14 received folic acid alone. Patient characteristics are presented, as well as the results of the 75g OGTT. A trend towards decreased rates of GDM is presented (which has not, however, reached statistical significance-p = .057). Glucose levels at 60 minutes were significantly reduced in the myo-inositol group. Conclusions: The findings of our study suggest a promising effect of myo-inositol which seems to decrease glucose levels during the 75 gr OGTT. Despite the fact that differences in rates of GDM were not statistically significant among women that received myo-inositol and those that did not, we believe that there is a trend that remains to be investigated during the complete results of our randomised trial.

Este trabajo examina la relación entre la accesibilidad de una vivienda con su entorno y su precio. A partir de un modelo de precios hedónicos se analiza el valor que le asignan las personas a tener accesibilidad a elementos de su entorno como equipamientos y redes de transporte. Los resultados indican que las personas valoran más habitar en lugares en los que puedan acceder a otros lugares que están a una distancia mayor a 12 000 m, pero a la vez valoran su privacidad, lo cual hace que prefieran viviendas más apartadas (en un radio menor a 500 m) de redes viales transitadas. Este resultado es relevante para la planeación urbana, porque sugiere que una política de desarrollo urbano podrá generar mayores beneficios para la población en tanto se enfoque a proveer mayor accesibilidad a mayores niveles de integración; a niveles menores es mejor que los propios agentes definan la configuración del entorno.
