RESUMO
INTRODUÇÃO: A percepção e satisfação corporal têm sido amplamente estudadas em diversos públicos, principalmente em estudantes universitários; porém, existem poucas investigações com vegetarianos, sendo assim, torna-se necessário avaliar se o padrão alimentar vegetariano está relacionado com os fenômenos inerentes à imagem corporal. OBJETIVO: Avaliar a percepção e a satisfação corporal entre estudantes universitários vegetarianos. MÉTODO: Trata-se de um estudo transversal com 123 participantes, no qual foram aplicados o Questionário de Imagem Corporal - BSQ (Body Shape Questionnaire) e a Escala de Silhuetas de Stunkard. RESULTADOS: Os dados mostraram que 86,2% dos participantes eram eutróficos (IMC=22,4±3,3), sendo o score obtido no BSQ foi de 84,6 pontos (±36,0) correspondente à leve insatisfação com a imagem corporal. Cerca de 82,1% dos estudantes se mostravam insatisfeitos com a silhueta, dentre estes, 61,4% desejavam diminuí-la. CONCLUSÃO: O padrão alimentar (ovolactovegetariano, lactovegetariano, vegetariano estrito e vegano) não se relacionou com a insatisfação corporal, mas sim o desejo de ter silhuetas magras que são valorizadas pelo padrão de beleza vigente.
INTRODUCTION: For Body perception and satisfaction have been widely studied among different publics, especially among college students; however, there are few investigations with vegetarians. Therefore, it is necessary to evaluate whether the vegetarian eating pattern is related to the phenomena inherent to body image. OBJECTIVE: To evaluate body perception and body satisfaction among vegetarian college students. METHOD: This is a cross-sectional study with 123 participants, in which the Body Image Questionnaire (BSQ) and the Stunkard Silhouette Scale were applied. RESULTS: The data showed that 86.2% of the participants were eutrophic (BMI=22.4±3.3), and the score obtained in the BSQ was 84.6 points (±36.0) corresponding to a mild dissatisfaction with body image. About 82.1% of the students were dissatisfied with their silhouette, and 61.4% of them wanted to reduce it. CONCLUSION: Dietary patterns (ovolactovegetarian, lactovegetarian, strict vegetarian, and vegan) were not related to body dissatisfaction, but rather the desire to have thin silhouettes that are valued by the prevailing beauty standard.

ABSTRACT Objective: This study evaluated the accuracy and precision of digital models acquisition using a home-built, low-cost scanning system based on the structured light method. Methods: a plaster model (PM) was scanned using the experimental device (SL) and a dental desktop scanner (DS). The teeth dimensions of PM and SL models were measured in triplicate, with a caliper and digitally, respectively. The agreement of the measurements of each model was evaluated using the intraclass correlation coefficient, and the validity between the different measurement techniques was assessed using the Bland-Altman analysis. The accuracy and precision of the models were qualitatively investigated using the mesh superposition of the SL and DS models. Results: A high intraclass correlation coefficient was observed in all models (PM=0.964; SL1=0.998; SL2=0.995; SL3=0.998), and there was no statistical difference between the measurements of the SL models (p>0.05). PM and SL model measurements were found to be in good agreement, with only 3.57% of the observed differences between the same measurement being located outside 95% limits of agreement according to Bland and Altman (0.43 and -0.40 mm). In the superimpositions of SL-SL and SL-DS models, areas of discrepancy greater than 0.5 mm were observed mainly in interproximal, occlusal, and cervical sites. Conclusion: These results indicate that the home-built SL scanning system did not possess sufficient accuracy and precision for many clinical applications. However, the consistency in preserving the dental proportions suggests that the equipment can be used for planning, storage, and simple clinical purposes.
RESUMO Objetivo: Este estudo avaliou a acurácia e a precisão da aquisição de modelos digitais utilizando um sistema de digitalização caseiro e de baixo custo baseado no método de luz estruturada. Material e Métodos: Para isso, um modelo de gesso (MG) foi digitalizado utilizando o dispositivo experimental (LE) e um scanner dental de mesa (SD). As dimensões dos dentes dos modelos MG e LE foram medidas em triplicata com um paquímetro e digitalmente, respectivamente. A concordância das medidas de cada modelo foi avaliada usando o coeficiente de correlação intraclasse, e a validade entre as diferentes técnicas de medição foi avaliada usando a análise de Bland-Altman. A acurácia e a precisão dos modelos foram investigadas qualitativamente usando a sobreposição de malhas dos modelos LE e SD. Resultados: Um alto coeficiente de correlação intraclasse foi observado em todos os modelos (MG=0,964; LE1=0,998; LE2=0,995; LE3=0,998) e não houve diferença estatística entre as medições dos modelos LE (p>0,05). As medições dos modelos MG e LE mostraram boa concordância, com apenas 3,57% das diferenças observadas entre as mesmas medições localizadas fora dos limites de concordância de 95% de acordo com a análise de Bland-Altman (0,43 e -0,40 mm). Nas sobreposições dos modelos LE-LE e LE-SD, foram observadas áreas de discrepância maiores que 0,5 mm principalmente nos sítios interproximais, oclusais e cervicais. Conclusões: Esses resultados indicam que o sistema de digitalização por luz estruturada caseiro não possui precisão e acurácia suficientes para muitas aplicações clínicas. No entanto, a consistência na preservação das proporções dentárias sugere que o equipamento pode ser usado para planejamento, armazenamento e propósitos clínicos simples.
RESUMO
ABSTRACT Purpose: Evaluation of lid contour and marginal peak point changes to compare outcomes of external levator advancement and Müller's muscle conjunctival resection surgery in unilateral ptosis. Methods: We reviewed the charts of unilateral ptosis patients who underwent external levator advancement or Müller's muscle conjunctival resection. Eyelid contour analysis was conducted on preoperative and 6-month postoperative digital images. This was performed with the multiple margin reflex distances technique, measuring the vertical distance from a line intersecting the center of the pupil to the eyelid margin at 10 positions at 2 mm intervals. The marginal peak point changes were analyzed digitally using the coordinates of the peak point according to the pupil center. Each position's mean distance was compared preoperatively, postoperatively, and with the fellow eyelid. Results: Sixteen patients underwent external levator advancement and 16 patients had Müller's muscle conjunctival resection. The mean margin reflex distance was improved by both techniques (1.46 vs. 2.43 mm and 1.12 vs. 2.25 mm, p=0.008 and p=0.0001 respectively) and approached that of the fellow eyelid (2.43 vs. 2.88 and 2.25 vs. 2.58 mm, p=0.23 and p=0.19, respectively). However, statistically significant lid margin elevation was limited to between the N6 and T6 points in the external levator advancement group. Whereas, significant elevation was achieved along the whole lid margin in the Müller's muscle conjunctival resection group. The marginal peak point was shifted slightly laterally in the external levator advancement group (p=0.11). Conclusions: Both techniques provide effective lid elevation, however, the external levator advancement's effect lessens toward the canthi while Müller's muscle conjunctival resection provides more uniform elevation across the lid margin. The margin reflex distance alone is not sufficient to reflect contour changes.
RESUMO
ABSTRACT Background: Colorectal cancer is one of the most prevalent pathologies worldwide whose prognosis is linked to early detection. Colonoscopy is the gold standard for screening, and diagnosis is usually made histologically from biopsies. Aiming to reduce the inspection and diagnostic time as well as the biopsies and resources involved, other techniques are being promoted to conduct accurate in vivo colonoscopy assessments. Optical biopsy aims to detect normal and neoplastic tissues analysing the autofluorescence spectrum based on the changes in the distribution and concentration of autofluorescent molecules caused by colorectal cancer. Therefore, the autofluorescence contribution analysed by image processing techniques could be an approach to a faster characterization of the target tissue. Objective: Quantify intensity parameters through digital processing of two data sets of three-dimensional widefield autofluorescence microscopy images, acquired by fresh colon tissue samples from a colorectal cancer murine model. Additionally, analyse the autofluorescence data to provide a characterization over a volume of approximately 50 µm of the colon mucosa for each image, at second (2nd), fourth (4th) and eighth (8th) weeks after colorectal cancer induction. Methods: Development of a colorectal cancer murine model using azoxymethane/dextran sodium sulphate induction, and data sets acquisition of Z-stack images by widefield autofluorescence microscopy, from control and colorectal cancer induced animals. Pre-processing steps of intensity value adjustments followed by quantification and characterization procedures using image processing workflow automation by Fiji's macros, and statistical data analysis. Results: The effectiveness of the colorectal cancer induction model was corroborated by a histological assessment to correlate and validate the link between histological and autofluorescence changes. The image digital processing methodology proposed was then performed on the three-dimensional images from control mice and from the 2nd, 4th, and 8th weeks after colorectal cancer chemical induction, for each data set. Statistical analyses found significant differences in the mean, standard deviation, and minimum parameters between control samples and those of the 2nd week after induction with respect to the 4th week of the first experimental study. This suggests that the characteristics of colorectal cancer can be detected after the 2nd week post-induction. Conclusion: The use of autofluorescence still exhibits levels of variability that prevent greater systematization of the data obtained during the progression of colorectal cancer. However, these preliminary outcomes could be considered an approach to the three-dimensional characterization of the autofluorescence of colorectal tissue, describing the autofluorescence features of samples coming from dysplasia to colorectal cancer.
RESUMO Contexto: O câncer colorretal é uma das patologias mais prevalentes em todo o mundo, cujo prognóstico está ligado à detecção precoce. A colonoscopia é o padrão ouro para triagem, e o diagnóstico geralmente é feito histologicamente a partir de biópsias. Visando reduzir o tempo de inspeção e diagnóstico, bem como as biópsias e recursos envolvidos, outras técnicas estão sendo promovidas para realizar avaliações precisas de colonoscopia in vivo. A biópsia óptica visa detectar tecidos normais e neoplásicos analisando o espectro de autofluorescência com base nas mudanças na distribuição e concentração de moléculas autofluorescentes causadas pelo câncer colorretal. Portanto, a contribuição da autofluorescência analisada por técnicas de processamento de imagem poderia ser uma abordagem para uma caracterização mais rápida do tecido-alvo. Objetivo: Quantificar parâmetros de intensidade por meio do processamento digital de dois conjuntos de dados de imagens de microscopia de autofluorescência em campo amplo tridimensionais, adquiridas por amostras de tecido fresco de cólon de um modelo murino de câncer colorretal. Adicionalmente, analisar os dados de autofluorescência para fornecer uma caracterização em um volume de aproximadamente 50 µm da mucosa do cólon para cada imagem, na segunda (2ª), quarta (4ª) e oitava (8ª) semanas após a indução do câncer colorretal. Método: Desenvolvimento de um modelo murino de câncer colorretal usando indução de azoximetano/sulfato de sódio dextrano, e aquisição de conjuntos de dados de imagens Z-stack por microscopia de autofluorescência em campo amplo, de animais controle e induzidos ao câncer colorretal. Etapas de pré-processamento de ajustes de valores de intensidade seguidas por procedimentos de quantificação e caracterização usando automação de fluxo de trabalho de processamento de imagem por macros do Fiji, e análise estatística de dados. Resultados: A eficácia do modelo de indução de câncer colorretal foi corroborada por uma avaliação histológica para correlacionar e validar a ligação entre as mudanças histológicas e de autofluorescência. A metodologia de processamento digital de imagem proposta foi então realizada nas imagens tridimensionais de camundongos controle e das 2ª, 4ª e 8ª semanas após a indução química do câncer colorretal, para cada conjunto de dados. Análises estatísticas encontraram diferenças significativas nos parâmetros médios, desvio padrão e mínimos entre amostras de controle e aquelas da 2ª semana após a indução em relação à 4ª semana do primeiro estudo experimental. Isso sugere que as características do câncer colorretal podem ser detectadas após a 2ª semana pós-indução. Conclusão: O uso de autofluorescência ainda apresenta níveis de variabilidade que impedem uma maior sistematização dos dados obtidos durante a progressão do câncer colorretal. No entanto, esses resultados preliminares podem ser considerados uma abordagem para a caracterização tridimensional da autofluorescência do tecido colorretal, descrevendo as características de autofluorescência de amostras que vão da displasia ao câncer colorretal.
RESUMO
Distorção da imagem corporal é uma alteração da percepção do corpo que pode repercutir na saúde. Este estudo visa estimar, entre mulheres participantes do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil) residentes na Bahia, Brasil, a prevalência de acurácia e distorção da imagem corporal e investigar associações com características socioeconômicas, estilo de vida e procura de cuidados ginecológicos. Participaram 609 mulheres de 50-69 anos de idade que responderam, entre 2012-2014, questionários aplicados face a face. Foi utilizada a escala de silhuetas de Stunkard para investigar a percepção acurada ou distorcida para mais ou menos peso. A razão de risco relativo (RR) foi calculada por meio de regressão logística multinomial por meio do Stata 13. A maioria das participantes tem perspectiva acurada do próprio corpo (53,7%). Entre aquelas com percepção distorcida, há uma tendência à distorção para menos peso (38,1%). Na análise de regressão multinomial, permaneceram associadas à distorção para menos peso as variáveis raça/cor e escolaridade, sendo que a primeira foi positivamente associada à distorção para menos peso entre as pardas (RR = 1,89; IC95%: 1,13-3,16) e pretas (RR = 2,10; IC95%: 1,25-3,55), enquanto a segunda entre aquelas com escolaridade até o Ensino Médio (RR = 1,65; IC95%: 1,18-2,33). Não houve associações quanto às demais variáveis, nem com distorção para mais peso. Os resultados contribuem para a explicação das relações entre percepção da imagem corporal e fatores socioeconômicos, revelando que mulheres de raça/cor diferentes e variados níveis de escolaridade são influenciadas de formas distintas pelos discursos sociais, o que impacta a percepção da sua imagem corporal.
Body image distortion is an alteration in the perception of the body that can have repercussions on health. This study aims to estimate the prevalence of body image accuracy and distortion among women participating in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) living in Bahia State, Brazil, and to investigate associations with socioeconomic characteristics, lifestyle, and gynecological care seeking. A total of 609 women aged 50 to 69 years participated in the study, who answered face-to-face questionnaires from 2012 to 2014. The Stunkard silhouette scale was used to investigate accurate or distorted perception for more or less weight. The relative risk ratio (RR) was calculated by multinomial logistic regression using Stata 13. Most participants have an accurate perception of their own bodies (53.7%). Among those with distorted perception, there is a tendency to distort towards less weight (38.1%). In the multinomial regression analysis, the variables race/skin color and education remained associated with the distortion towards underweight. The race/skin color variable was positively associated with the distortion towards underweight among Mixed-race women (RR = 1.89; 95%CI: 1.13-3.16) and black (RR = 2.10; 95%CI: 1.25-3.55), while the education variable among those with up to high school education (RR = 1.65; 95%CI: 1.18-2.33). There were no associations with the other variables or with distortion for more weight. The results contribute to explaining the relationships between body image perception and socioeconomic factors, revealing that women of different races/skin colors and varying educational levels are influenced in different ways by social discourses, impacting the perception of their body image.

RESUMO
SUMMARY OBJECTIVE: This study aimed to evaluate cardiac contractility in fetuses from pregestational diabetes mellitus pregnancies by three-dimensional ultrasound using spatiotemporal image correlation in rendering mode. METHODS: A retrospective cross-sectional study was performed on 40 fetuses from nondiabetic pregnancies and 28 pregestational diabetic pregnancies between 20 and 33 weeks and 6 days. Cardiac contractility was assessed by measuring the ventricular myocardial area in diastole subtracted from the ventricular myocardial area in systole. RESULTS: Pregestational diabetic pregnancies had a lower maternal age than nondiabetic pregnancies (26.7 vs. 39.9 years, p=0.019). Cardiac contractility in fetuses from diabetic and nondiabetic pregnancies was similar (p=0.293). A moderately positive and significant correlation was observed between gestational age and cardiac contractility (r=0.46, p=0.0004). A 1-week increase in gestational age was responsible for a 0.1386 cm2 increase in cardiac contractility. CONCLUSION: Cardiac contractility as evaluated by three-dimensional ultrasound using spatiotemporal image correlation in rendering mode showed no significant differences across fetuses with and without pregestational diabetes.
RESUMO
ABSTRACT Purpose: This study aimed to evaluate the classification performance of pretrained convolutional neural network models or architectures using fundus image dataset containing eight disease labels. Methods: A publicly available ocular disease intelligent recognition database has been used for the diagnosis of eight diseases. This ocular disease intelligent recognition database has a total of 10,000 fundus images from both eyes of 5,000 patients for the following eight diseases: healthy, diabetic retinopathy, glaucoma, cataract, age-related macular degeneration, hypertension, myopia, and others. Ocular disease classification performances were investigated by constructing three pretrained convolutional neural network architectures including VGG16, Inceptionv3, and ResNet50 models with adaptive moment optimizer. These models were implemented in Google Colab, which made the task straight-forward without spending hours installing the environment and supporting libraries. To evaluate the effectiveness of the models, the dataset was divided into 70%, 10%, and 20% for training, validation, and testing, respectively. For each classification, the training images were augmented to 10,000 fundus images. Results: ResNet50 achieved an accuracy of 97.1%; sensitivity, 78.5%; specificity, 98.5%; and precision, 79.7%, and had the best area under the curve and final score to classify cataract (area under the curve = 0.964, final score = 0.903). By contrast, VGG16 achieved an accuracy of 96.2%; sensitivity, 56.9%; specificity, 99.2%; precision, 84.1%; area under the curve, 0.949; and final score, 0.857. Conclusions: These results demonstrate the ability of the pretrained convolutional neural network architectures to identify ophthalmological diseases from fundus images. ResNet50 can be a good architecture to solve problems in disease detection and classification of glaucoma, cataract, hypertension, and myopia; Inceptionv3 for age-related macular degeneration, and other disease; and VGG16 for normal and diabetic retinopathy.

As imagens de treinamento foram expandidas para 10.000 imagens de fundo de olho para cada tal. Resultados: Observou-se que o modelo ResNet50 alcançou acurácia de 97,1%, sensibilidade de 78,5%, especificidade de 98,5% e precisão de 79,7% e teve a melhor área sob a curva e pontuação final para classificar a categoria da catarata (área sob a curva=0,964, final=0,903). Em contraste, o modelo VGG16 alcançou uma precisão de 96,2%, sensibilidade de 56,9%, especificidade de 99,2% e precisão de 84,1%, área sob a curva 0,949 e pontuação final de 0,857. Conclusão: Esses resultados demonstram a capacidade das arquiteturas de rede neural convolucional pré-treinadas em identificar doenças oftalmológicas a partir de imagens de fundo de olho. ResNet50 pode ser uma boa solução para resolver problemas na detecção e classificação de doenças como glaucoma, catarata, hipertensão e miopia; Inceptionv3 para degeneração macular relacionada à idade e outras doenças; e VGG16 para retinopatia normal e diabética.
RESUMO
Resumo Este estudo objetivou identificar padrões alimentares e avaliar a associação entre percepção da imagem corporal e esses padrões em escolares. Um estudo transversal foi conduzido em 385 escolares (ambos os sexos, 10-17 anos de idade) de 4 escolas públicas de Salvador, Brasil. Dois recordatórios alimentares de 24h não consecutivos foram aplicados e o padrão alimentar foi determinado por Análise Fatorial Exploratória, após ajuste dos dados dietéticos pelo Multiple Source Method. Para avaliar percepção da imagem corporal, nós usamos uma escala brasileira de silhuetas. Avaliamos as associações entre percepção da imagem corporal e padrões alimentares usando o modelo de regressão logística politômica ajustado para covariáveis. Três padrões alimentares foram obtidos: "padrão ocidental", "padrão saudável" e "comidas típicas/junk food". Após ajuste, adolescentes que desejavam uma silhueta menor (2,48 [IC95%: 1,04-6,11], 3,49 [IC95%: 1,35-9,05] e 2,87 [IC95%: 1,13-7,26]) tinham mais chances de aderir aos quintis de menor consumo do padrão ocidental, comparados àqueles satisfeitos com sua imagem corporal. Nenhuma associação foi identificada nos outros dois padrões alimentares. Adolescentes insatisfeitos com seus corpos tendem a aderir menos a padrões alimentares não saudáveis.
Abstract This study aimed to identify dietary patterns and to evaluate the association between body image perception and these patterns among schoolchildren. A cross-sectional study was conducted on 385 schoolchildren (both sexes, 10-17 years old) from four public schools in Salvador, Brazil. Two non-consecutive 24-hour dietary recalls were applied, and the dietary pattern was determined by Exploratory Factor Analysis after adjustment of dietary data using the Multiple Source Method. To evaluate body image perception, the Brazilian body shape silhouette was used. The associations between body image perception and dietary patterns using the polytomous logistic regression model adjusted for covariables was assessed. Three dietary patterns were obtained: "Western standard," unhealthy, "healthy pattern" and "typical dishes/ junk food." After adjustment, adolescents who wished for a slimmer silhouette (2.48 [95%CI: 1.04-6.11], 3.49 [95%CI: 1.35-9.05] and 2.87 [95%CI: 1.13-7.26]) were more likely to adhere to the quintiles with the lowest consumption of the Western standard, compared to those satisfied with their body image. No associations were identified in the other two dietary patterns. Adolescents dissatisfied with their bodies tend to adhere less to unhealthy dietary patterns.
RESUMO
@#BACKGROUND: Ischemic stroke refers to a disorder in the blood supply to a local area of brain tissue for various reasons and is characterized by high morbidity, mortality, and disability. Early reperfusion of brain tissue at risk of injury is crucial for the treatment of acute ischemic stroke. The purpose of this study was to evaluate comfort levels in managing acute stroke patients with hypoxemia who required endotracheal intubation after multidisciplinary in situ simulation training and to shorten the door-to-image time. METHODS: This quality improvement project utilized a comprehensive multidisciplinary in situ simulation exercise. A total of 53 participants completed the two-day in situ simulation training. The main outcome was the self-reported comfort levels of participants in managing acute stroke patients with hypoxemia requiring endotracheal intubation before and after simulation training. A 5-point Likert scale was used to measure participant comfort. A paired-sample t-test was used to compare the mean self-reported comfort scores of participants, as well as the endotracheal intubation time and door-to-image time on the first and second days of in situ simulation training. The door-to-image time before and after the training was also recorded. RESULTS: The findings indicated that in situ simulation training could enhance participant comfort when managing acute stroke patients with hypoxemia who required endotracheal intubation and shorten door-to-image time. For the emergency management of hypoxemia or tracheal intubation, the mean post-training self-reported comfort score was significantly higher than the mean pre-training comfort score (hypoxemia: 4.53±0.64 vs. 3.62±0.69, t= -11.046, P<0.001; tracheal intubation: 3.98±0.72 vs. 3.43±0.72, t= -6.940, P<0.001). We also observed a decrease in the tracheal intubation and door-to-image time and a decreasing trend in the door-to-image time, which continued after the training. CONCLUSION: Our study demonstrates that the implementation of in situ simulation training in a clinical environment with a multidisciplinary approach may improve the ability and confidence of stroke team members, optimize the first-aid process, and effectively shorten the door-to-image time of stroke patients with emergency complications.
RESUMO
In the context of the current era when different civilizations are learning from each other， traditional Chinese medicine （TCM） needs to continuously draw the essence from modern scientific and technological civilization for creative inheritance and innovative development. It is essential to master the classic texts of TCM to solidify its theoretical foundation， while also read extensively to broaden the academic horizons. TCM's inheritance and innovation should be integrated with the current era's context and social reality， and delve into the essence of TCM's academic experience and clinical practice. Emphasis should be placed on the inheritance of original TCM thinking， and return to the original image creation and transformation. Using image thinking as the main approach， and combined it with modern complex systems science and front-edge methodologies， we could elaborate the TCM theories such as correspondence between nature and human， five circuits and six qi， constitution and endowment， and harmony of body and spirit. The training of academic talents must be at the forefront， closely follow the new trends of the development of contemporary scientific and technological civilization， identify the “pain points” of discipline development， focus on the key areas for improvement， and seek the highlights of academic research. There should be a courage to question and propose new insights， construct new concepts， establish new theories， transform the weakness in original theoretical innovation， and enrich the evolving connotation of TCM.

RESUMO
Resumen: Objetivo: Explorar el impacto del uso cotidiano de plataformas de videollamadas en las cogniciones, emociones y comportamientos relacionados con la autoimagen en pacientes con Trastornos del Comportamiento Alimentario (TCA) y personas de la población general, durante la pandemia por COVID-19. Métodos: Sesenta y ocho pacientes con TCA en tratamiento y 106 personas de la población general respondieron a un cuestionario diseñado para el estudio a través de Lime Survey; (98.5 y 79.2% respectivamente eran mujeres), con edad promedio de 17.6 (DE:3.47) y 33.5 (DE:9.35) respectivamente. Las pacientes discutieron y explicaron sus respuestas en cinco sesiones de terapia grupal presenciales dirigidas por un psiquiatra. Posteriormente, se realizó un análisis temático reflexivo con un enfoque inductivo para determinar las categorías. Resultados: Los pacientes reportaron una mayor incomodidad frente a la cámara, preocupación con la apariencia física, miedo a la crítica, vergüenza y sentimientos de vulnerabilidad, comparados con las personas de la población general. Predominaron los pensamientos negativos sobre la forma y el tamaño del rostro y otras partes del cuerpo y las conductas de chequeo y/o evitación de la imagen corporal, que interfirieron con la concentración y el rendimiento. Conclusión: además del impacto negativo de la pandemia de COVID-19 en la salud mental, la nueva virtualidad desafía a los clínicos a enfrentar dificultades adicionales con la imagen corporal en pacientes con TCA y alerta a la detección de nuevas preocupaciones dismórficas también en la población general.
Abstract: Objective: To explore the impact of video call platforms on physical appearance concerns (cognitions, emotions and behaviors) in Eating Disorders (ED) patients and in general population, during COVID 19 pandemic. Methods: Sixty-eight patients attending a treatment program for ED, and 106 people from the general population responded to a questionnaire designed for the study through Lime Survey; (98.5 and 79.2% respectively were women), with a mean age of 17.6 (SD:3.47) and 33.5 (SD:9.35) respectively. Patients discussed and explained their answers in five in vivo group therapy sessions directed by a psychiatrist. Then, a reflective thematic analysis with an inductive approach to determine the categories was performed. Results: Patients reported a higher discomfort in front of the camera, preoccupation with physical appearance, fear of criticism, embarrassment, and feelings of vulnerability, compared with general population. Negative thoughts about the shape and size of the face and other body parts predominated, as well as body image checking/avoidance behaviors that interfered with concentration and performance. Conclusion: In addition to the negative impact of the COVID-19 pandemic on mental health, the new virtuality challenges clinicians to face additional body image difficulties in ED patients and alerts on the detection of dysmorphic concerns in the general population as well.

RESUMO
RESUMEN La imagen corporal varía a lo largo de la vida. Los cambios físicos que conlleva la adolescencia, pueden influir en el desarrollo de conductas de riesgo para trastornos alimentarios. Aunque los factores sociales y culturales afectan la imagen corporal, las formas de interacción modernas, mediante el uso de tecnología, en particular las redes sociales, permiten controlar la autopresentación de la imagen corporal en las fotografías que son publicadas, lo que podría servir como indicador de conductas de riesgo alimentarias. El objetivo de este trabajo fue establecer la asociación de conductas alimentarias de riesgo con el control de la imagen corporal en fotografías, para analizar su invarianza factorial por sexo y proponer puntos de corte en población mexicana. La muestra estuvo conformada por 1 155 adolescentes (51.3 % hombres y 48.7 % mujeres), con una media de edad de 15.18 años. Se utilizó el cuestionario en español sobre el control de la imagen corporal en fotografías denominado BICP-S, además del cuestionario de conductas alimentarias de riesgo (CAR). Los resultados evidenciaron una relación entre las conductas alimentarias de riesgo y el control de la imagen en fotografías. La estructura factorial del BICP-S varía en función del sexo, por lo que se proponen diferentes puntos de corte del cuestionario, en donde aquellas ubicadas en el percentil 85 indican riesgo acerca de las preocupaciones por la imagen corporal en mujeres, mientras que en hombres se establece en el percentil 92, con una alta confiabilidad en el control de la imagen en ambos sexos (α > 0.90). El cuestionario tiene utilidad clínica para la detección de jóvenes con serias preocupaciones en torno a la imagen corporal que, de continuar, pueden constituirse en un factor de riesgo para trastornos de la conducta alimentaria.
ABSTRACT Body varies throughout life. Physical changes that take place during teenage years may influence the development of risky behaviors related to eating disorders. Although social and cultural factors affect body image, modern forms of interaction with technology, particularly social networks, allow controlling the self-presentation of body image in the photographs that are published, which could serve as an indicator of risky eating behaviors. The aim of this study was to establish the association of risky eating behaviors with the body image control in photographies, to analyze the factorial invariance by sex and to propose cut-off points in the Mexican population. The sample consisted of 1 155 adolescents (51.3 % males and 48.7 % females), with a mean age of 15.18 years. The BICP-S was used, in addition to the risky eating behaviors questionnaire (CAR). The results showed a relationship between risky eating behaviors and image control in photographs. The factorial structure of the BICP-S varies according to sex, so different cut-off points of the questionnaire are proposed, where those located at the 85th percentile indicate risk about body image concerns in women, while in men it is established at the 92nd percentile, with a high reliability in image control in both groups (α > 0.90). It is concluded that the questionnaire has clinical utility for the detection of at-risk youth who may have serious body image concerns, which if continued can be a risk factor for eating disorders.
RESUMO
Abstract Objectives: To present and execute a protocol for the capture of 3D facial images using photogrammetry through the open access software Blender and its add-on OrtogOnBlender (OOB) and to evaluate the compatibility of the 3D meshes generated with Computed tomography (CT) of the sinuses. Methods: Individuals > 18 years old, candidates for Rhinoseptoplasty in a tertiary hospital, were submitted to a photographic session to perform the standardized protocol. In the session, divided into 3 phases, sequential photos were taken for processing the photogrammetry in the OOB and producing 3D meshes of the face. The photogrammetry reconstructions were compared with the reference mesh of the soft tissue surface of the Sinus CT scan to assess compatibility between them. Results: 21 patients were included, 67% female. 3 photogrammetry meshes and 1 CT reference mesh were generated, which demonstrated matching compatibility, as most of the mean distances between cloud points were <1.48mm. Phase 3 of the session with the highest number of photos (54.36 ± 15.05) generated the most satisfactory mesh with the best resolution. Conclusions: The proposed protocol is reproducible and feasible in clinical practice, generated satisfactory 3D meshes of the face, being a potential tool for surgical planning and comparison of results. For the implementation of photogrammetry for use in 3D anthropometry, it is necessary to validate this method. Level of evidence: 3.

RESUMO
Trata-se de uma pesquisa realizada a partir de uma perspectiva psicossocial, que buscou relacionar a satisfação corporal de jovens adultos com suas práticas corporais e o uso que fazem de redes sociais virtuais. Participaram do estudo 207 jovens, que responderam um questionário online autoaplicado, cujas respostas foram tratadas com estatística descritiva e inferencial. Os resultados indicaram que a satisfação corporal é mais presente entre os praticantes de atividades físicas, e, em contrapartida, observou-se menor satisfação corporal entre os participantes mais aderentes a dietas e cirurgias plásticas estéticas. Algumas práticas corporais encontraram associação estatística significativa com o uso das redes sociais virtuais: praticantes de atividade física as acessam por menor tempo diário e visualizam conteúdos alusivos à saúde; dietas e cirurgias plásticas estão associadas ao maior acesso a conteúdos de influenciadores digitais. Assim, a satisfação corporal e a forma como jovens utilizam redes sociais virtuais podem ter influência sobre suas práticas corporais.
This was a study conducted from a psychosocial perspective, which sought to relate the body satisfaction of young adults with their body practices and the use they make of virtual social networks. Participants were 207 young people who answered a self-administered online questionnaire, whose responses were treated using descriptive and inferential statistics. Body satisfaction was more present among practitioners of physical activities, and, on the other hand, low body satisfaction was observed among participants more adherent to diets and aesthetic plastic surgeries. Some bodily practices were significantly associated with the use of virtual social networks: practitioners of physical activity access them for less time daily and view content alluding to health; diets and plastic surgery are associated with greater access to content from digital influencers. Thus, body satisfaction and the way young people use virtual social networks can influence their body practices.
RESUMO
Introdução: A procura pela cirurgia de contorno corporal após a cirurgia bariátrica se deve em grande parte a uma insatisfação com a imagem corporal prejudicada pela flacidez e excesso de pele decorrente da grande perda ponderal. O objetivo deste estudo foi avaliar a qualidade de vida e a imagem corporal de pacientes submetidos a cirurgia bariátrica e posteriormente a cirurgia de contorno corporal em uma clínica privada. Método: Este estudo transversal comparou 4 grupos distintos de 21 pacientes cada, pareados por índice de massa corporal e idade antes de realizarem a cirurgia bariátrica. Foram divididos nos tempos antes/depois da cirurgia bariátrica e antes/depois da cirurgia de contorno corporal, formando assim os grupos A, B, C e D, respectivamente. Foi utilizado o questionário SF-36 para avaliação da qualidade de vida e a Escala de Silhuetas proposta por Kakeshita para avaliação da imagem corporal. Para o nível de significância, foi escolhido p<0,05. Resultados: Houve melhora em todos os domínios do SF-36 após a cirurgia bariátrica. Os pacientes que procuraram a cirurgia de contorno corporal apresentaram o menor valor do componente de saúde mental, com pouca alteração após a cirurgia de contorno corporal. Quase todos os grupos superestimaram a sua silhueta, exceto para o grupo de 6 meses após a cirurgia bariátrica, que se viu menor. Conclusão: Pacientes bariátricos que procuram a cirurgia de contorno corporal apresentam escores inferiores de qualidade de vida relacionada à saúde mental e que permanecem menores após a cirurgia de contorno corporal. A distorção da imagem corporal e expectativas irreais podem justificar esse achado.
Introduction: The demand for body contouring surgery after bariatric surgery is largely due to dissatisfaction with body image impaired by sagging and excess skin resulting from massive weight loss. This study aimed to evaluate the quality of life and body image of patients undergoing bariatric surgery and body contouring surgery in a private clinic. Method: This cross-sectional study compared 4 groups of 21 patients, matched by body mass index and age before undergoing bariatric surgery. They were divided into times before/after bariatric surgery and before/after body contouring surgery, thus forming groups A, B, C, and D, respectively. The SF-36 questionnaire assessed the quality of life, and the Silhouette Scale proposed by Kakeshita to assess body image. For the significance level, p<0.05 was chosen. Results: There was an improvement in all SF-36 domains after bariatric surgery. Patients who sought body contouring surgery had the lowest mental health component value, with little change after body contouring surgery. Almost all groups overestimated their silhouette, except for the group of 6 months after bariatric surgery, which saw itself as smaller. Conclusion: Bariatric patients seeking body contouring surgery have lower mental health-related quality of life scores that remain lower after body contouring surgery.
RESUMO
Introducción: La elastografía cualitativa por ecografía endoscópica es una técnica para examinar las propiedades elásticas de los tejidos, que puede distinguir la fibrosis del tumor mediante patrones de colores. Objetivo: Determinar el valor de la elastografía por patrones de colores en la reestadificación del cáncer de recto. Métodos: Se efectuó un estudio observacional y descriptivo (serie de casos) de 54 pacientes con cáncer de recto atendidos en el Centro Nacional de Cirugía de Mínimo Acceso, en La Habana, entre septiembre del 2018 y diciembre del 2022, a quienes se les realizó elastografía por ecografía endoscópica para la reevaluación del tumor. Para determinar el valor de dicha técnica se calculó la sensibilidad, la especificidad, los valores predictivos positivo y negativo, las razones de verosimilitud positiva y negativa, así como el índice de Youden. Se estableció la concordancia diagnóstica según el índice kappa y el estudio histológico de la muestra tomada fue el estándar de referencia. Resultados: La concordancia de la elastografía con el resultado anatomopatológico fue buena (κ=0,84). La especificidad y el índice de validez resultaron ser de 91,7 y 94,4 %, respectivamente; mientras que el valor predictivo negativo fue de 84,6 %. Los 16 pacientes con patrón elastográfico mixto (ye3) tenían tumor residual localizado en alguna de las capas de la pared del recto. El índice de Youden alcanzó valores cercanos a 1. Conclusiones: El valor de esta técnica radica en su especificidad diagnóstica y en el valor predictivo negativo al diferenciar la fibrosis del tumor residual en la pared rectal.
Introduction: The qualitative elastography by endoscopic echography is a technique to examine the elastic properties of tissues that can distinguish the fibrosis of the tumor by means of color patterns. Objective: To determine the value of elastography by color patterns in the reestadification of the rectum cancer. Methods: An observational and descriptive study (serial cases) of 54 patients with rectum cancer was carried out, who were assisted in the National Center of Minimum Access Surgery, in Havana, between September, 2018 and December, 2022 to whom elastography by endoscopic echography were carried out for the reevaluation of the tumor. To determine the value of this technique the sensibility, specificity, the predictive positive and negative values, the positive and negative true ratio, as well as the index of Youden were calculated. The diagnostic consistency was established according to the kappa index and the histologic study of the sample was the reference standard. Results: The elastography consistency with the pathologic result was good (ĸ=0.84). The specificity and the index of validity were 91.7 and 94.4%, respectively; while the negative predictive value was 84.6%. The 16 patients with mixed elastographic pattern (ye3) had residual tumor located in some of the layers of the rectum wall. The Youden index reached values close to 1. Conclusions: The value of this technique resides in its diagnostic specificity and negative predictive value when differentiating fibrosis from the residual tumor in the rectal wall.

Currently, for adolescents and young people, body appearance is considered important to be accepted in social groups. Correspondingly, the objective of the research was to determine the correlation between the satisfaction of body image with the practice of physical exercise, in adolescents from 12 to 18 years of age of the Educational Unit "Leonardo Maldonado Pérez", in the school year 2020- 2021. The study was quantitative correlational of a non-experimental cross-sectional type, which made it possible to measure the correlation between the body image variables and the practice of physical exercise. For data collection, two instruments were applied: the Body shape Questionnaire, to explore the level of body satisfaction and the identification of dissatisfaction about weight and the Self-report of the Stage of Change for Physical Exercise, to assess the intention to practice physical exercise. The sampling was stratified proportional and simple random of 400 students divided into six groups. The result was a significant high negative correlation between the level of dissatisfaction with body image and the practice of physical exercise. It was determined that the students seek the satisfaction of their body image through the practice of physical exercise, since having a better image motivates the responsibility of staying healthy, through the moderate practice of exercises in different spaces, so that they place it as a personal goal.
