Diabetes immersion training as teaching method to medical practitioners

Este estudo avaliou a eficácia do método de ensino teórico e prático sobre diabetes e a atitude de profissionais médicos quanto à realização de controle glicêmico intensivo. Participaram de um curso de imersão em diabetes, com dois dias de duração, 48 médicos-residentes de clínica médica ou endocrinologia. Os participantes receberam treinamento de monitorização de glicemia capilar, técnicas de aplicação de insulina e contagem de carboidratos, sendo orientados a se portarem como diabéticos e a seguir prescrição médica individual. Foram avaliados através de questionários. No questionário de conhecimentos, observou-se um aumento significante de 12% no índice de acertos entre o início e o final do curso (61,2% e 73,2%, respectivamente, com p < 0,0001). Antes do curso, 70,8% dos participantes diziam ter dificuldades na contagem de carboidratos e 89,6%, na automonitorização glicêmica. Após a experiência prática, 82,9% dos participantes encontraram dificuldades na realização de contagem de carboidratos e 80,8%, na automonitorização; 40,4% fizeram uso de todas as medicações prescritas e 36,1% monitorizaram todas as glicemias. Os resultados deste estudo mostram que esse tipo de curso é eficaz para a aquisição de conhecimentos e contribui com a sensibilização do profissional médico quanto às dificuldades cotidianas enfrentadas pelo portador de diabetes melito na aderência às recomendações.This study evaluated the effectiveness of theoretical and practical teaching method in diabetes and doctors' position about feasibility of intensive blood glucose control. Forty-eight internal medicine or endocrinology residents participated in a two-day diabetes immersion course. The participants received training on self-blood glucose monitoring, techniques of insulin administration and carbohydrate counting. They were also instructed to behave as patients with diabetes and to follow individual medical prescription. They were assessed through questionnaires. In knowledge assessment, a significant increase of 12% was observed between the beginning and the end of the course (61.2% and 73.2%, respectively, with p < 0.0001). Before the course, 70.8% and 89.6% of the participants believed there were complications in performing carbohydrate counting and blood glucose monitoring, respectively. After the experience, 82.9% of them had difficulties in carbohydrate counting and 80.8% in self-monitoring; 40.4% took all medications prescribed and 36.1% monitored blood glucose correctly. These results show that the methodology of this course is an effective way to disseminate knowledge and that it contributes to doctors becoming more sensitive to daily problems faced by patients with diabetes melito concerning the acceptance of medical recommendations

Evaluation of short‐term safety of ultrasound‐guided foetal fluid sampling in the dog (Canis lupus familiaris)

Background: In humans, analysis of amniotic fluid is widely used for diagnostic and prognostic purposes. Amniocentesis has scarcely been used in veterinary medicine to date, despite a tremendous potential for clinical and research applications in dogs. Our study aimed to establish a safe method for foetal fluid sampling in female dogs. Methods: Two transabdominal ultrasound-guided methods were assessed: the "free hand" and the needle-guided bracket sampling. In addition, through a subsequent routinely scheduled ovariohysterectomy, fluid was directly collected. Samples from 98 conceptuses were collected at day 46.7 +/- 7.5 of pregnancy. Results: The amount of fluid retrieved varied between 0.5 and 5.0 ml per collection. Macroscopic examination of the uterus and conceptuses identified 53% of the puncture sites. Neither fluid leakage nor foetal injury was detected, and six hematomas (5.8%) were visible. Ultrasound-guided foetal fluid collection was found to be potentially safe, and it can be performed by using either transabdominal method. Conclusion: Foetal fluid collection is possible with relative ease and low short-term risk, and may open paths for diagnostic, therapeutic and research purposes in dogs. The procedure can provide new insights into prenatal clinical medicine, including diagnostics of foetal deaths, early identification of heritable diseases and so on

Gaze-Based Human-Robot Interaction by the Brunswick Model

We present a new paradigm for human-robot interaction based on social signal processing, and in particular on the Brunswick model. Originally, the Brunswick model copes with face-to-face dyadic interaction, assuming that the interactants are communicating through a continuous exchange of non verbal social signals, in addition to the spoken messages. Social signals have to be interpreted, thanks to a proper recognition phase that considers visual and audio information. The Brunswick model allows to quantitatively evaluate the quality of the interaction using statistical tools which measure how effective is the recognition phase. In this paper we cast this theory when one of the interactants is a robot; in this case, the recognition phase performed by the robot and the human have to be revised w.r.t. the original model. The model is applied to Berrick, a recent open-source low-cost robotic head platform, where the gazing is the social signal to be considered

Optimization of a robotics gaze control system

Producción CientíficaGaze control is an important issue in the interaction between a robot and humans. In particular, the decision of who to pay attention to in a multi-party conversation is a way of improving a robot’s naturalness in human-robot interaction. A system based on a competitive neural network can decide who to look at with a smooth transition in the focus of attention when significant changes in stimuli are produced. One important aspect in this process is the configuration of the different parameters of such a neural network. The weights of the different stimuli have to be computed in order to achieve behavior similar to humans. This article explains how these weights can be obtained by solving an optimization problem. The experiments carried out and some results are also presented

The role of gaze as a deictic cue in human robot interaction

© Springer Nature Switzerland AG 2020.Gaze has a major role in social interaction. As a deictic reference, gaze aims at attracting visual attention of a communication partner to a referred entity in the environment. Gaze direction in natural faces is a well-investigated domain of research at behavioral and neurophysiological levels. However, our knowledge about deictic role of gaze in Human Robot Interaction is limited. The present study focuses on a comparative analysis of the deictic role of gaze direction in alternative face morphologies. We report an experimental study that investigated deictic gaze in a virtual reality environment. Human participants identified object locations by utilizing deictic gaze cues provided by avatar faces, as well as natural human faces. Our findings reveal a facilitating role in the accuracy of objection detection in favor of gaze embedded in natural faces compared to gaze embedded in synthetic avatar face morphologies
