    The aim of this study was to collect and analyze ultrasound measurements of fetal-maternal structures during normal and pathological pregnancies in jennies, a livestock species of growing interest. For two breeding seasons, 38 jennies of different breeds and crossbreeds aged between 3 and 18 years were monitored weekly by transrectal examination using a portable Esaote ultrasound (MyLab\u2122 30 GOLD VET) with a 5\u20137.5 MHz probe. The jennies were divided into two groups, < 250 kg and >250 kg body weight, and the dates of conception and parturition/abortion were recorded to calculate pregnancy length. Descriptive statistics were performed for the following variables: pregnancy length and maternal-fetal parameters (measurements of the orbit, gastric bubble, thorax, abdomen, gonads, heart rate, umbilical artery velocimetry, and combined utero-placental thickness). A total of 68 pregnancies were studied, 36 of which ended during the study period. The average pregnancy length was 370.82 \ub1 16.6 days for full-term pregnancies (N = 28, 77.8%) and 316.13 \ub1 36.6 days for abortions (N = 8, 22.2%). The season of conception and fetal gender did not affect the pregnancy length. Pregnancy examination can reasonably be performed by two weeks after last service if ovulation date is not known. The orbital diameter was the most reliable parameter for monitoring the physiological development of the embryo and fetus, and it was strongly related to the gestational age. No differences in fetal development were observed in relation to the mother's body weight. The combined utero-placental thickness was not associated with the gestational age and thickening and edema, frequently observed, were not associated with fetal pathologies

    BACKGROUND: Liver metastases (LMs) from thyroid cancer (TC) are relatively uncommon in clinical practice and their management is challenging. Interventional radiology loco-regional treatments (LRTs), including radiofrequency ablation (RFA) and trans-arterial chemoembolization (TACE), have been successfully employed to treat LMs from various types of cancer. METHODS: We analyzed the role of LRTs in the management of unresectable LMs from differentiated and medullary TCs performed at our institution from 2015 to 2020. A review of the available English literature regarding this topic was also performed. RESULTS: Six hepatic LRTs were performed in 4 TC patients with LMs, in 2 cases after the start of treatment with a tyrosine kinase inhibitor (TKI). A partial response was obtained in 2 patients; the diameter of the largest targeted lesion was 18 mm in both of them. The remaining procedures were performed on larger lesions and a stable disease was achieved in all but one case. Acute LRT-related complications were transient and mild. In literature, the largest studies were focused on TACE in LMs from MTC, showing good tolerance and remarkable disease control, especially in case of limited liver tumour involvement. CONCLUSION: LRTs for LMs represent a valuable option for the treatment of metastatic TC in case of isolated hepatic progression or for symptoms relief, also after the start of TKI treatment as part of a multimodal approach. The best disease control is obtained when hepatic metastatic burden is limited. These procedures are generally well tolerated; however, a cautious multidisciplinary selection of the candidates is mandatory

    Educción de dinámica de tecleo centrado en el contexto emocional de un individuo

    El proyecto se orienta al desarrollo de un Framework que permita determinar las relaciones entre el estado emocional de un individuo, adquirido a través una interfaz cerebro—computadora (BMI), con su dinámica de tecleo. La investigación se enfoca en definir un entorno de trabajo donde se puedan analizar modelos posibles del estado emocional adquirido, descubrir los cambios temporales en la cadencia de tecleo que de ellos resultan y analizarlos buscando predictibilidad y patrones de adaptación a mediano plazo. En el último año exploramos la forma en que los usuarios varían su dinámica de tecleo a lo largo del tiempo. Utilizando el principio de variación paralela, hay una forma de “olvidar” lo aprendido e ir reemplazándolo por datos actualizados. También estamos explorando nuevos campos en la dinámica de tecleo, que incluyen la detección del estado emocional del usuario y el modelado de textos libres utilizando contextos finitos en forma similar a los esquemas de compresión de datos con predicción por coincidencia parcial.Eje: Seguridad InformáticaRed de Universidades con Carreras en Informática (RedUNCI
