Artificial intelligence-based analysis of tumor-infiltrating lymphocyte spatial distribution for colorectal cancer prognosis / 中华医学杂志(英文版)

BACKGROUND@#Artificial intelligence (AI) technology represented by deep learning has made remarkable achievements in digital pathology, enhancing the accuracy and reliability of diagnosis and prognosis evaluation. The spatial distribution of CD3 + and CD8 + T cells within the tumor microenvironment has been demonstrated to have a significant impact on the prognosis of colorectal cancer (CRC). This study aimed to investigate CD3 CT (CD3 + T cells density in the core of the tumor [CT]) prognostic ability in patients with CRC by using AI technology.@*METHODS@#The study involved the enrollment of 492 patients from two distinct medical centers, with 358 patients assigned to the training cohort and an additional 134 patients allocated to the validation cohort. To facilitate tissue segmentation and T-cells quantification in whole-slide images (WSIs), a fully automated workflow based on deep learning was devised. Upon the completion of tissue segmentation and subsequent cell segmentation, a comprehensive analysis was conducted.@*RESULTS@#The evaluation of various positive T cell densities revealed comparable discriminatory ability between CD3 CT and CD3-CD8 (the combination of CD3 + and CD8 + T cells density within the CT and invasive margin) in predicting mortality (C-index in training cohort: 0.65 vs. 0.64; validation cohort: 0.69 vs. 0.69). The CD3 CT was confirmed as an independent prognostic factor, with high CD3 CT density associated with increased overall survival (OS) in the training cohort (hazard ratio [HR] = 0.22, 95% confidence interval [CI]: 0.12-0.38, P <0.001) and validation cohort (HR = 0.21, 95% CI: 0.05-0.92, P = 0.037).@*CONCLUSIONS@#We quantify the spatial distribution of CD3 + and CD8 + T cells within tissue regions in WSIs using AI technology. The CD3 CT confirmed as a stage-independent predictor for OS in CRC patients. Moreover, CD3 CT shows promise in simplifying the CD3-CD8 system and facilitating its practical application in clinical settings.

An evaluation of carrier detection for Spinal muscular atrophy using digital PCR assay / 中华医学遗传学杂志

OBJECTIVE@#To assess the effectiveness and feasibility of carrier detection for Spinal muscular atrophy (SMA) by using digital PCR assay.@*METHODS@#Peripheral blood samples were collected from 214 pregnant women who were routinely screened for SMA carriers, of which 204 were randomly selected samples and 10 were samples with known copy numbers of SMN1 exons 7 and 8. Samples with known copy numbers of SMN1 exons 7 and 8 were randomly mixed into the experiment to validate the performance of the digital PCR assay.@*RESULTS@#The copy numbers of SMN1 exons 7 and 8 and SMN2 exons 7 and 8 in peripheral blood samples were detected by digital PCR assay. The results of SMN1 exons 7 and 8 were compared with those of the quantitative PCR method to assess the reliability and clinical performance of the digital PCR assay. Among the 204 random samples, digital PCR has detected five samples with simultaneous heterozygous deletion of SMN1 exons 7 and 8, three samples with heterozygous deletion of SMN1 exon 8 only, and 196 samples with no deletion of SMN1 exons 7 and 8. Ten samples with known SMN1 exons 7 and 8 copy numbers were detected with the expected values. The digital PCR test results were fully consistent with that of the quantitative PCR.@*CONCLUSION@#The results of digital PCR for the detection of copy number variation of SMN1 exons 7 and 8 were consistent with qPCR. Digital PCR assay was able to clearly distinguish the copy number of the target genes, therefore can be used for SMA carrier screening. Moreover, it can also detect copy number of SMN2 exons 7 and 8, which can provide more information for genetic counseling.

Scale development and validation of perimenopausal women disability index in the workplace

BACKGROUND@#Menopausal disorders include obscure symptomatology that greatly reduce work productivity among female workers. Quantifying the impact of menopause-related symptoms on work productivity is very difficult because no such guidelines exist to date. We aimed to develop a scale of overall health status for working women in the perimenopausal period.@*METHODS@#In September, 2021, we conducted an Internet web survey which included 3,645 female workers aged 45-56 years in perimenopausal period. We asked the participants to answer 76 items relevant to menopausal symptomatology, that were created for this study and performed exploratory and confirmatory factor analyses for the scale development. Cronbach's alpha, receiver operating characteristic analysis, and logistic regression analysis were used to verify the developed scale.@*RESULTS@#Approximately 85% participants did not have menstruation or disrupted cycles. Explanatory factor analysis using the maximum likelihood method and Promax rotation identified 21 items with a four-factor structure: psychological symptoms (8 items, α = 0.96); physiological symptoms (6 items, alpha = 0.87); sleep difficulty (4 items, alpha = 0.92); human relationship (3 items, alpha = 0.92). Confirmatory factor analyses found excellent model fit for the four-factor model (RMSR = 0.079; TLI = 0.929; CFI = 0.938). Criterion and concurrent validity were confirmed with high correlation coefficients between each of the four factors, previously validated menopausal symptom questionnaire, and Copenhagen Burnout Inventory scales, respectively (all ps < 0.0001). The developed scale was able to predict absenteeism with 78% sensitivity, 58% specificity, and an AUC of 0.727 (95%CI: 0.696-0.757). Higher scores of each factor as well as total score of the scale were more likely to be associated with work absence experience due to menopause-related symptoms even after adjusting for Copenhagen Burnout Inventory subscales (all ps < 0.0001).@*CONCLUSION@#We found that the developed scale has high validity and reliability and could be a significant indicator of absenteeism for working women in perimenopausal period.

Cross-cultural Validation of the Health Mindset Scale for Brazil / Validação transcultural da Escala de Mindset Direcionado à Saúde no Brasil

Abstract Objective To cross-culturally validate the Health Mindset Scale for Brazil, as well as adapt the terms and questionnaires for adequate understanding of Brazilians, using factor analysis as an instrument to validate its reliability. Methods Cross-cultural validation of the Health Mindset Scale into Brazilian Portuguese using the Beaton method, Cronbach's alpha calculation and factor analysis Results The sample consisted of 215 patients aged between 18 and 87 years (M = 41.98; SD = 15.72), with a mean age between 31 and 50 years (42.0%), and female (52 .6%), a marginally significant difference (p < 0.10) between men and women was observed for item 3. In this item, men's mean (M = 5.48; SD = 0.99) was higher than the average for women (M = 5.10; SD = 1.22), with a small effect size for the difference (d = 0.26). Pearson's r correlation coefficient was examined between the mean score and age (r = −0.21; p = 0.002), the result of which indicated a weak, negative and significant linear relationship. The older the age, the lower the average score on the Health Mindset Scale. Conclusion The version of the health-focused mindset scale for Brazilian Portuguese was introduced and cross-culturally validated, demonstrating good reliability with a Cronbach's alpha of 0.786. Consequently, it constitutes a new instrument for clinical practice and can be correlated with established scales in the literature.

Prevalence of internet addiction and psychological factors in adolescents during the covid-19 pandemic / Prevalência de dependência da internet e fatores psicológicos em adolescentes durante a pandemia de covid-19 / Prevalencia de la adicción a internet y factores psicológicos en adolescentes durante la pandemia de la covid-19

Addictive behaviors related to Internet are becoming more common and this tool has been essential once it enables home office, entertainment, homeschooling, and easy access to information. Despite the easiness brought by technology, the exaggerated use has affected users in different ways, including in the development of psychiatric disorders. This study aimed to assess internet addiction, depression, anxiety, attention-deficit/hyperactivity disorder (ADHD), attention, impulsivity, and stress in 48 adolescents (26 young women and 22 young men), aged from 15 to 18 years, with a mean age of 16.74 (0.61), mostly students of public schools, during COVID-19, to investigate correlations between these variables according to sex and sociodemographic aspects. To assess the factors, the Internet Addiction Test (IAT); the Swanson, Nolan, and Pelham Rating Scale (SNAP-IV) Questionnaire ; the Depression, Anxiety, and Stress scale for brazilian adolescents (EDAE-A); the Barratt Impulsiveness Scale (BIS-11); and a sociodemographic questionnaire were applied. The data collection was performed in schools located in southern Brazil. The results indicated that 12 out of 48 adolescents were considered addicted to the Internet. Moreover, Internet addiction was a predictor of depression in regression analysis (p<0.001). In addition, participants classified as more addicted to the Internet scored lower averages in general attention (p<0.035) and higher averages in behavioral symptoms of inattention and ADHD (p<0.050), stress (p<0.003), anxiety (p<0.016), and depression (p<0.015), with effect sizes ranging from moderate to high. Therefore, the intense internet use by adolescents might cause psychological consequences such as depression in adolescents. Family support and professional intervention might help in the reduction of symptoms and consequences of internet addiction as well as in its prevention.(AU)

A dependência de internet é cada vez mais comum, pois essa ferramenta tem se tornado imprescindível, uma vez que possibilita home office, entretenimento, educação domiciliar e fácil acesso às informações. No entanto, o uso exagerado da tecnologia afeta os usuários de diversas formas, inclusive no desenvolvimento de transtornos psiquiátricos. Este estudo visou avaliar a dependência de internet, depressão, ansiedade, hiperatividade, atenção, impulsividade e estresse em 48 adolescentes (26 meninas e 22 meninos) de 15 a 18 anos, com idade média de 16,74 (0,61), estudantes de escolas públicas do Sul do Brasil durante a covid-19, para investigar correlações entre as variáveis anteriores de acordo com gênero e aspectos sociodemográficos. Para avaliar, aplicou-se o Internet Addiction Test (IAT), um teste de atenção, escala SNAP IV, escala de depressão, ansiedade e estresse para adolescentes (EDAE-A), escala de impulsividade de Barratt e um questionário sociodemográfico. Os resultados indicaram que 12 adolescentes foram considerados viciados em internet, e que a dependência desta foi preditora da depressão na análise de regressão (p < 0,001). Ainda, os participantes classificados como adictos tiveram médias mais baixas em atenção geral (p < 0,035) e mais altas em sintomas comportamentais de desatenção e hiperatividade (p < 0,050), estresse (p < 0,003), ansiedade (p < 0,016) e depressão (p < 0,015), com efeitos que variaram de moderado a alto. Portanto, o uso intenso da internet por adolescentes pode ter consequências psicológicas, como a depressão. Bom apoio familiar e intervenção profissional podem ajudar na redução dos sintomas e consequências, bem como na prevenção da dependência.(AU)

La adicción a Internet es cada vez más habitual, puesto que esta herramienta es esencial para el trabajo remoto, el entretenimiento, la educación domiciliar y el fácil acceso a la información. Sin embargo, su uso exagerado afecta a la vida de las personas de diferentes maneras, incluso en el desarrollo de trastornos psiquiátricos. El objetivo de este estudio fue evaluar la adicción a Internet, depresión, ansiedad, hiperactividad, atención, impulsividad y estrés en 48 adolescentes (26 muchachas y 22 muchachos), de entre 15 y 18 años, con una edad promedio de 16,74 (0,61), en su mayoría estudiantes de escuelas públicas del Sur de Brasil, durante la pandemia de la COVID-19, para investigar las correlaciones entre las variables mencionadas según género y aspectos sociodemográficos. Para evaluar los factores, se aplicaron el Test de Adicción a Internet (TAI), un test de atención, la escala SNAP IV, la Escala de Depresión, Ansiedad y Estrés para adolescentes (EDAE-A), la escala de impulsividad de Barratt y un cuestionario sociodemográfico. Los resultados indicaron que 12 adolescentes fueron considerados adictos a Internet, además, la adicción a Internet fue un predictor de la depresión en el análisis de regresión (p<0,001). Igualmente, los participantes clasificados como más adictos a Internet tuvieron promedios más bajos en atención general (p<0,035), y más altos en síntomas conductuales de falta de atención e hiperactividad (p<0,050), estrés (p<0,003), ansiedad (p<0,016) y depresión (p<0,015), con efectos que varían de moderado a alto. Por lo tanto, el uso intenso podría producir consecuencias psicológicas como la depresión en los adolescentes. Tener un buen apoyo familiar e intervención profesional puede ayudar a reducir los síntomas y las consecuencias de la adicción a Internet, así como prevenirla.(AU)

Fathering children aged from 2 to 10: psychometric properties of the IFI-BR-27 / Paternidade com filhos entre 2 e 10 anos de idade: propriedades psicométricas do IFI-BR-27 / Paternidad con hijos de entre 2 y 10 años: propiedades psicométricas del IFI-BR-27

The Inventory of Father Involvement (IFI) was developed to examine paternal involvement among men with children from 5 to 10 years of age. However, father involvement affects child development starting in the child's infancy. In Brazil, a revised version of the instrument (called the IFI-BR-27) was developed to use with fathers of children in a wider age group (2 to 10 years). Thus, in this study we aimed to investigate evidence for validity of this revised version based on internal structure, measurement invariance, and evidence of convergent validity. For this purpose, 572 Brazilian fathers completed a sociodemographic questionnaire, the IFI-BR-27, and either the Father Engagement Questionnaire (FEQ; for fathers of children in early childhood education settings) or the Inventory of Parenting Practices (IPP; for fathers of children in elementary school). Results of confirmatory factor analyses indicated the plausibility of a second-order internal structure for the IFI-BR-27 (χ 2 / df = 3.526; CFI = .937; TLI = .929; RMSEA = .066). Composite reliability for the nine factors varied from .65 to .84. Invariance analyses indicated that the structure is independent of the child's educational setting. Evidence of convergent validity was also found ( r = .67 - FEQ; r = .58 - IPP). Therefore, the IFI-BR-27 is an adequate tool to assess the quality of father involvement for fathers of children in preschool or elementary school. The IFI-BR-27 can contribute to further scientific research, aiding in longitudinal studies, as well as helping professionals to evaluate and encourage specific dimensions of father involvement.(AU)

O Inventory of Father Involvement (IFI) foi desenvolvido para avaliar o envolvimento paterno de homens com filhos de 5 a 10 anos. No entanto, envolvimento paterno afeta o desenvolvimento de crianças desde a primeira infância. No Brasil, uma versão revisada dessa medida (chamada de IFI-BR-27) foi desenvolvida para uso com pais de crianças em uma faixa etária mais ampla (2 a 10 anos). O objetivo deste estudo foi, portanto, investigar evidências de validade dessa versão revisada com base na estrutura interna, invariância de medida e evidências de validade convergente. Para isso, 572 pais brasileiros preencheram um questionário sociodemográfico, o IFI-BR-27 e o Questionário de Engajamento Paterno (QEP; para pais com filhos no Ensino Infantil) e o Inventário de Práticas Parentais (IPP; para pais com filhos no Ensino Fundamental 1). Os resultados de análises fatoriais confirmatórias indicaram a plausibilidade de uma estrutura interna de segunda ordem para o IFI-BR-27 (χ 2 / gl = 3,526; CFI = 0,937; TLI = 0,929; RMSEA = 0,066). A confiabilidade composta para os nove fatores variou de 0,65 a 0,84. Análises de invariância indicaram que a estrutura é independente do ciclo escolar da criança. Também foram encontradas evidências de validade convergente ( r = 0,67 - QEP; r = 0,58 - IPP). Assim, considera-se o IFI-BR-27 uma medida adequada para avaliar a qualidade do envolvimento paterno de pais de crianças do Ensino Infantil ao Fundamental 1. O IFI-BR-27 poderá contribuir para melhorias científicas, viabilizando estudos longitudinais e ajudando profissionais a avaliar e promover dimensões específicas do envolvimento paterno.(AU)

El Inventory of Father Involvement (IFI) se desarrolló para evaluar la participación paterna en la crianza de hijos de entre 5 y 10 años de edad. Es sabido que la participación paterna contribuye al desarrollo infantil desde la primera infancia. En Brasil, una versión brasileña de este instrumento (la IFI-BR-27) se desarrolló para aplicarse a padres con hijos de un grupo de edad más amplio (de 2 a 10 años). Este estudio tuvo por objetivo comprobar evidencia de validez de esta versión revisada con base en la estructura interna, la invariancia del instrumento y la evidencia de validez convergente. Para ello, 572 padres brasileños completaron un cuestionario sociodemográfico, el IFI-BR-27 y el Cuestionario de Involucramiento Paterno (CIP; para padres de niños en el jardín de infantes) y el Inventario de Prácticas Parentales (IPP; para padres de niños en la primaria). Los resultados de los análisis factoriales confirmatorios indicaron la plausibilidad de una estructura interna de segundo orden para el IFI-BR-27 (χ 2 / gl = 3,526; CFI = 0,937; TLI = 0,929; RMSEA =0,066). La confiabilidad compuesta para los nueve factores varió de 0,65 a 0,84. Los análisis de invariancia indicaron que la estructura es independiente del ciclo educativo del niño. También se encontró evidencia de validez convergente ( r =0,67 - CIP; r = 0,58 - IPP). Por lo tanto, el IFI-BR-27 es un instrumento adecuado para evaluar la calidad de participación paterna de padres con hijos en edad preescolar o en la primaria. El IFI-BR-27 permitirá un mayor desarrollo científico, permitiendo estudios longitudinales y ayudando a los profesionales a evaluar y fomentar dimensiones específicas de participación paterna.(AU)

Confiabilidad Inter-evaluador en la Medición del Grosor Muscular y el Ángulo de Penación a través de la Evaluación Ecográfica: Estudio entre un Experto y un Kinesiólogo en Formación / Inter-Evaluator Reliability in Measurement of Muscle Thickness and Penance Angle through Ultrasound Evaluation: Comparison Study between an Expert and a Physical Therapist in Training

Existen diversas formas de evaluar el músculo esquelético. Una herramienta que ha ganado relevancia es la evaluación ecográfica. Esta, permite medir el grosor muscular (GM) y el ángulo de penación (AP). Por otra parte, en la formación inicial de los Kinesiólogos es importante realizar el ejercicio de la confiabilidad en la medición en relación al experto. un procedimiento diagnóstico. Así, el objetivo de este estudio es determinar la confiabilidad inter-evaluador en la medición del GM y el AP, a través de la evaluación ecográfica, entre un experto y un kinesiólogo en formación. La capacitación contó de tres fases; el ciclo teórico, el ciclo práctico y el proceso de confiabilidad. Para este último, se realizaron 10 pruebas para cada una de las mediciones GM 1, GM 2 y GM 3 y de AP. La confiabilidad inter-evaluador en la medición de GM es buena a excelente en los tres intentos GM1 (ICC=0,81; p=0,001), GM2 (ICC=0,86; p<0,001), GM3 (ICC=0,88;<0,001). Por su parte, la confiabilidad del AP fue pobre a regular (ICC=0,21; p=0,143. Las conclusiones de esta investigación indican que existe una excelente confiabilidad inter evaluador en la medición de GM. No así, en la medición de AP, por lo que se sugiere incrementar las horas prácticas en el proceso de aprendizaje de esta medida.

SUMMARY: Skeletal muscle can be assessed in a number of different ways. Consequently, ultrasound evaluation has become a relevant diagnostic tool. This procedure allows measuring muscle thickness (MT) and pennation angle (PA). Furthermore, during the initial training of physical therapists it is important in a diagnostic procedure, to exercise reliability in measurement in comparison to the expert. Therefore, the objective of this study is to determine the inter-rater reliability in the measurement of MT and PA, through ultrasound evaluation, between an expert and a physical therapist in training. This training was comprised of three phases: The theoretical cycle, the practical cycle and the reliability process. For the latter, ten different tests were performed for each of the MT 1, MT 2 and MT 3 and PA measurements. Inter-rater reliability in the MT measurement was good to excellent in the three attempts MT1 (ICC=0.81; p=0.001), MT2 (ICC=0.86; p<0.001), MT3 (ICC=0. 88;<0.001). On the other hand, reliability of the PA was poor to fair (ICC=0.21; p=0.143. In conclusion, this research indicates that there is excellent inter-rater reliability in the measurement of MT. This does not however apply to the measurement of PA. It is therefore suggested that practical hours during the learning process of this measure be increased.

Revisión narrativa de escalas para cribado de trastorno obsesivo compulsivo y adaptación cultural uruguaya / Revisione narrativa delle scale di screening dei disturbi disturbo ossessivo compulsivo e adattamento culturale uruguaiano

El trastorno obsesivo compulsivo es diagnosticado tardíamente, factor que empeora su pronóstico. Contar con una escala de cribado facilitaría el diagnóstico oportuno. Los objetivos de este trabajo fueron seleccionar la escala más adecuada para cribado de trastorno obsesivo compulsivo en adultos y someterla a un proceso de adaptación cultural uruguaya. Se efectuó una revisión narrativa de escalas diseñadas para cribado de este trastorno en Internet, entre febrero y mayo de 2021. Las escalas fueron analizadas según una lista de criterios preestablecidos, que permitió descartar progresivamente aquellas que no reunían las condiciones: extensión menor a 30 ítems, método autoaplicado, adecuadas propiedades psicométricas, punto de corte establecido para la detección, incluir las temáticas y presentaciones características de la patología. Seleccionado el inventario, se efectuó su traducción directa y reversa, y revisión conceptual por comité de expertas. Fue seleccionada la escala Florida Obsessive Compulsive Inventory (FOCI), que presenta buena apariencia lógica, lenguaje accesible y una sensibilidad del 92 % para detección de trastorno obsesivo compulsivo. De su adaptación cultural se obtuvo una versión preliminar en lenguaje regional. La versión preliminar de FOCI deberá ser testeada cualitativamente en estudio piloto, donde será completada por usuarios con trastorno obsesivo compulsivo, para obtener una versión regional equivalente a la original.

Obsessive-compulsive disorder is diagnosed late, a factor that worsens its prognosis. Having a screening scale would facilitate timely diagnosis. The objectives are to select the most appropriate scale for obsessive-compulsive disorder screening in adults and submit it to a process of Uruguaiyan cultural adaptation. Between February and May 2021, a narrative review of scales designed for that disorder screening on the Internet was carried out. The scales were analyzed according to a list of pre-established criteria, which made it possible to progressively discard those that did not meet the conditions: an extension less than 30 items, self-applied method, adequate psychometric properties, cut-off point established for the detection, including the topics and characteristic presentations of the pathology. Once the inventory was selected, its direct and reverse translation was carried out, as well as a conceptual review by a committee of experts. The Florida Obsessive Compulsive Inventory (FOCI) scale was selected, which presents good logical appearance, accessible language and a sensitivity of 92 % for obsessive-compulsive disorder screening. From its cultural adaptation, a preliminary version in regional language was obtained. The preliminary version of FOCI must be qualitatively tested in a pilot study, where it will be completed by users with obsessive-compulsive disorder, in order to obtain a regional version equivalent to the original.

Diseño y validación de una escala de soporte social para adolescentes / Design and validation of a social support scale for adolescents

Introducción: el soporte social es de gran importancia en la adolescencia; aquellos adolescentes con mayor soporte tienen mejores estrategias de salud. Existen pocos instrumentos para evaluar el soporte social en todas sus dimensiones y las fuentes de éste, ninguno ha sido validado en español. El objetivo de este estudio es evaluar la validez y confiabilidad de un nuevo instrumento para identificar el soporte social y la fuente de este soporte en adolescentes. Material y métodos: la escala de soporte social para adolescentes (ESSA) consiste en un cuestionario de autoaplicación de 22 ítems, con cinco opciones de respuesta tipo Likert que van de nunca a siempre, con seis subescalas: familia, mejor amigo, compañeros de clase, profesores, otras relaciones, y salud general y oral. Los datos de la ESSA se recogieron de estudiantes de secundaria (N = 191; edad media 16.1 ± 1.2 años). Los análisis psicométricos incluyeron análisis factorial de ejes principales, consistencia interna (alfa de Cronbach) y correlaciones de la escala con la Escala Multidimensional de Apoyo Social Percibido (MSPSS) y la Escala de Depresión 20 del Centro de Estudios Epidemiológicos (CESD20) (correlaciones de Spearman, p). Resultados: el análisis factorial de ejes principales mostró que la escala explica el 72.23% de la variabilidad. La escala completa mostró una consistencia interna adecuada, con un alfa de Cronbach = 0.92 [0.90-0.93]. En cuanto a la validez discriminativa, la correlación con las puntuaciones de la escala CES-D20 fue ρ = -0.32, la escala mostró una fuerte correlación con las puntuaciones MSPSS (p = 0.81). Los resultados fueron estables en la repetibilidad (ICC = 0.93). Conclusiones: la ESSA es válida y confiable. Este instrumento podría ser adecuado para una amplia gama de aplicaciones de investigación entre la población adolescente (AU)

Introduction: social support is of great importance in adolescence; those who have more support have better health strategies. There are few instruments to evaluate social support in all its dimensions and the sources of this support, and none has been validated in Spanish. The aim of this study is to evaluate the validity and reliability of a new instrument to identify social support and the source of this support for adolescents. Material and methods: the adolescent social support scale (ADSSS) consists of a 22-item self-report questionnaire with 5 Likert-type responses ranging from never to always and six different subscales: family, best friend, classmates, teachers, other relationships, and general and oral health. ADSSS data were collected from high school students (N = 191; mean age 16.1 years [standard deviation = 1.2]). Psychometric analyses included main axis factor analysis, internal consistency (Cronbach's alpha), and scale correlations with the multidimensional scale of perceived social support (MSPSS) and the Center for Epidemiologic Studies Depression Scale-20 (CES-D20) (Spearman correlations, p). Results: main axis factor analysis showed that the scale explained 72.23% of the variability. The entire scale showed adequate internal consistency, with Cronbach's alpha = 0.92 [0.90-0.93]. For discriminative validity, the correlation with CES-D20 scores was p = -0.32, and the scale showed a strong correlation with MSPSS scores (p = 0.81). The results were stable across repeated measurements (ICC = 0.93). Conclusions: the ADSSS has good reliability and validity. This instrument could be suitable for a broad range of research applications among adolescents (AU)

Estudio de concordancia de radiografía-tomografía computarizada de las fracturas de radio distal / Radiography-computed tomography concordance study of distal radius fractures

Introducción: La fractura de radio distal resulta común en la extremidad superior y representa un reto terapéutico. Objetivo: Determinar la concordancia entre radiografía simple y tomografía computarizada con respecto a las clasificaciones AO Foundation y de Fernández, y la elección del tratamiento. Métodos: Se realizó un estudio de concordancia diagnóstica entre radiografía simple y tomografía computarizada. Ortopedistas y cirujanos de mano analizaron 19 imágenes de fracturas de radio distal de acuerdo con las clasificaciones AO Foundation y de Fernández, y las distintas opciones de tratamiento. Para el grado de concordancia se usó el coeficiente Kappa de Fleiss. La prueba de t-Student y Chi cuadrado diferenciaron los grupos para variables cuantitativas y cualitativas, respectivamente. Hubo una significancia estadística de p= 0,05. Resultados: La clasificación de Fernández coincidió mejor que la clasificación AO Foundation entre radiografía y tomografía computarizada. En la elección del tratamiento y la técnica de osteosíntesis la concordancia fue mayor al 90 por ciento, mientras que el abordaje quirúrgico solo alcanzó el 50 por ciento. La clasificación AO Foundation radiográfica se correspondió con fracturas complejas, mientras la de Fernández con las menos complicadas. Las fracturas se subestimaron cuando se clasificaron con radiografía. Conclusiones: La relación de las clasificaciones entre radiografía y tomografía computarizada para fracturas de radio distal no resulta satisfactoria. La tomografía computarizada ofrece información que modifica las decisiones en el tratamiento(AU)

Introduction: Distal radius fracture is common in the upper extremity and represents a therapeutic challenge. Objective: To determine the agreement between simple radiography and computed tomography with respect to AO Foundation and Fernández classifications, and the choice of treatment. Methods: A diagnostic agreement study was carried out between simple radiography and computed tomography. Orthopedists and hand surgeons analyzed 19 images of distal radius fractures according to AO Foundation and Fernández classifications, and the different treatment options. Fleiss Kappa coefficient was used for the degree of agreement. The Student's t-test and chi-square differentiated the groups for quantitative and qualitative variables, respectively. There was a statistical significance of p = 0.05. Results: Fernández classification coincided better than AO Foundation between radiography and computed tomography. In the choice of treatment and osteosynthesis technique, agreement was greater than 90 percent, while the surgical approach only reached 50 percent. The radiographic AO Foundation classification corresponded to complex fractures while Fernández classification corresponded to less complicated ones. Fractures were underestimated when classified with radiography. Conclusions: The relationship of classifications between radiography and computed tomography for distal radius fractures is not satisfactory. Computed tomography provides information that modifies treatment decisions(AU)
