Face Images

More than 500 painful intervetions are carried out during the hospitalization of a newborn baby in an intensive medical care unit. In these situations, there is, however, a challenging difficulty to identify pain, owing to the unlikeliness of direct and objective verbal communication commonly used among adults. This work is part of an on-going research that aims to develop a computational framework to interpreting and recognizing patterns on face images for automatic assessment of neonatal procedural pain. We believe that such investigation might provide relevant information to understand the relation between neonatal facial features and procedural pain and, consequently, helping health professionals in the corresponding clinical practice.

This article highlights that the standardization of medical care in the U.S. relies on clinical practice guidelines (CPGs), which indicate institutionalized norms about when and under what circumstances it is appropriate to administer specific medical tests and courses of treatment. However, when CPGs in medicine derive from medical research that was informed by since-debunked ideas about race, they may also facilitate structural racism.

Machine Learning Models

Machine learning models have been successfully applied for analysis of skin images. However, due to the black box nature of such deep learning models, it is difficult to understand their underlying reasoning. This prevents a human from validating whether the model is right for the right reasons. Spurious correlations and other biases in data can cause a model to base its predictions on such artefacts rather than on the true relevant information. These learned shortcuts can in turn cause incorrect performance estimates and can result in unexpected outcomes when the model is applied in clinical practice. This study presents a method to detect and quantify this shortcut learning in trained classifiers for skin cancer diagnosis, since it is known that dermoscopy images can contain artefacts. Specifically, we train a standard VGG16-based skin cancer classifier on the public ISIC dataset, for which colour calibration charts (elliptical, coloured patches) occur only in benign images and not in malignant ones. Our methodology artificially inserts those patches and uses inpainting to automatically remove patches from images to assess the changes in predictions. We find that our standard classifier partly bases its predictions of benign images on the presence of such a coloured patch. More importantly, by artificially inserting coloured patches into malignant images, we show that shortcut learning results in a significant increase in misdiagnoses, making the classifier unreliable when used in clinical practice. With our results, we, therefore, want to increase awareness of the risks of using black box machine learning models trained on potentially biased datasets. Finally, we present a model-agnostic method to neutralise shortcut learning by removing the bias in the training dataset by exchanging coloured patches with benign skin tissue using image inpainting and re-training the classifier on this de-biased dataset.

AbstractVisual memory for faces has been extensively researched, especially regarding the main factors that influence face memorability. However, what we remember exactly about a face, namely, the pictorial content of visual memory, remains largely unclear. The current work aims to elucidate this issue by reconstructing face images from both perceptual and memory-based behavioural data. Specifically, our work builds upon and further validates the hypothesis that visual memory and perception share a common representational basis underlying facial identity recognition. To this end, we derived facial features directly from perceptual data and then used such features for image reconstruction separately from perception and memory data. Successful levels of reconstruction were achieved in both cases for newly-learned faces as well as for familiar faces retrieved from long-term memory. Theoretically, this work provides insights into the content of memory-based representations while, practically, it opens the path to novel applications, such as computer-based ‘sketch artists’.

Abstract Ultimately, there has been an increase in the number of cases of newborns affected by microcephaly, knowledge of the caregiver's perceptions regarding the child with microcephaly may promote the construction of therapeutic plans by health professionals that meet the expressed current needs of the child and caregivers. Thus, the aim of the present study is to describe the perception of family caregivers about microcephaly, using Callista Roy's adaptation theory. The research is descriptive, exploratory and with qualitative approach and was conducted at a School Clinic, located in the municipality of Juazeiro do Norte. The research participants were family caregivers of children diagnosed with microcephaly. Minayo's thematic analysis was used, supported by Roy's adaptation theory. Through data analysis two categories emerged: Knowledge and perception of family caregivers about microcephaly and family as support to cope with difficulties. It was observed that mothers, faced with the condition of their son with microcephaly, tend to develop a certain level of adaptation to make the situation less traumatic, making use of available social, medical care and family devices. Therefore, it is emphasized that health professionals need to act effectively in care, facilitating and strengthening effective adaptive responses. Keywords: Microcephaly, child, family caregiver, Nursing Theories. Resumo Nos últimos anos, o número de casos de recém-nascidos acometidos por microcefalia aumentou vertiginosamente, o conhecimento das percepções do cuidador em relação à criança com microcefalia pode fomentar a construção de planos terapêuticos por parte dos profissionais de saúde que atendam às necessidades vigentes expressas da criança e dos cuidadores. Assim, objetivo do presente estudo é descrever a percepção dos cuidadores familiares acerca da microcefalia, à luz da teoria da adaptação de Callista Roy. A pesquisa é descritiva, exploratória e com abordagem qualitativa. A pesquisa foi conduzida em uma Clínica Escola, localizada no município de Juazeiro do Norte. Os participantes da pesquisa foram cuidadores familiares de crianças com diagnóstico de microcefalia. Utilizou-se a análise temática de Minayo, sendo sustentada pela teoria da adaptação de Roy. Através da análise dos dados surgiram duas categorias: Conhecimento e percepção dos cuidadores familiares sobre a microcefalia e a família como apoio no enfrentamento das dificuldades. Observou-se que as mães, frente à condição do filho com microcefalia, tendem a desenvolver certo nível de adaptação para tornar a situação menos traumática, valendo-se dos dispositivos sociais, assistenciais e familiares disponíveis. Destaca-se, portanto, que os profissionais da saúde precisam atuar de forma eficaz na assistência, facilitando e fortalecendo as respostas adaptativas eficazes.

Background: Cardiovascular and respiratory diseases are leading causes of morbidity and their co-occurrence has important implications in mortality and other outcomes. Even the most recent guidelines do not reliably address clinical, prognostic, and therapeutic concerns due to the overlap of respiratory and cardiac diseases. Study objectives and design: In order to evaluate in the reality of clinical practice the epidemiology and the reciprocal impact of cardio-pulmonary comorbidity on the clinical management, diagnostic workup and treatment, 1,500 cardiac and 1,500 respiratory inpatients, admitted in acute and rehabilitation units, will be enrolled in a multicenter, nationwide, prospective observational study. For this purpose, each center will enroll at least 50 consecutive patients. At discharge, data analysis will be aimed at the definition of cardiac and pulmonary inpatient comorbidity prevalence, demographic characteristics, length of hospital stay, and risk factors, taking into account also procedures, pharmacological and non-pharmacological treatment, and follow up in patients with cardio-respiratory comorbidity. Conclusions: The purely observational design of the study aims to give new relevant information on the assessment and management of overlapping patients in real life clinical practice, and new insight for improvement and implementation of current guidelines on the management of individual diseases.

Harmonization of European and Russian standards of the quality of the delivery of school health services and competencies for school health professionals allowed to justify the concept of the evaluation of the quality of the delivery of medical help to students in educational institutions. The concept does not prescribe a concrete methodfor the organizing school health services, unified process of the activity of health professionals. The concept consists of 7 groups of indices of quality and competences of health care workers. Quality criteria include the presence of a regulatory framework, indices of benevolence towards children, social equity and access to health care for students, requirements for premises, equipment of medical rooms in schools, cooperation with the administration and teachers of schools, parents and children, the medical community, the requirements for health care workers, a minimum list of services, covering both population and individual needs of students, the secure storage, the management and use ofpersonal medical data of children and adolescents. The competences of the staff of medical units are determined by provided medical services and technologies of the work. Properly medical competences of workers of medical care units for the delivery of medical aid to students are contributed by willingness to ensure the rights of children in the process of health care delivery in the educational organization, skills in the field of communication, sharing of information with children, parents and teachers, cooperation with colleagues, planning and coordination of the organization of medical care, the provision of sanitary epidemiological well-being of students, informational-elucidative activity for shaping of healthy lifestyle, research activity. Concept is the basis of the algorithm of the evaluation of the quality of the delivery of medical aid to students and quality assessment technology as well by medical organizations and institutions, as in the form of an independent audit of the quality of the delivery of medical aid to students in educational institutions.
