Factor analysis and validation of the Bush Francis catatonia rating scale-Spain version

Background and objectives The aim of this study was to assess the reliability and validity of the Bush Francis Catatonia Screening Instrument and Bush Francis Catatonia Rating Scale Spain Version (BFCSI-SV and BFCRS-SV) using the ICD-11 and DSM-5 diagnostic criteria as well as other catatonia scales. Methods One hundred patients were admitted to the inpatient psychiatry unit at Hospital Universitari Germans Trias I Pujol and two psychiatrists administered the BFCRS-SV to the first 10 patients to assess inter-rater reliability. The BFCRS-SV, BFCSI-SV, Modified Rogers Scale (MRS), Abnormal Involuntary Movement Scales, Barnes Akathisia Rating Scale, and Modified Simpson-Angus Scale were then employed. Results The results showed that 27% of patients had catatonia using the DSM-5 diagnostic criteria. Additionally, 51% of patients had 2 or more BFCRSI-SV items (Sensitivity: 100%; Specificity: 67.12%). The alpha coefficient values were 0.80 and 0.84 for the BFCSI-SV and BFCRS-SV, respectively, and the intraclass correlation coefficient values were 0.902 and 0.903. The area under the ROC curve was 0.971 and 0.96, and the instruments had a strong positive correlation with the DSM-5 score, ICD-11 score, and MRS. The study identified a three-factor model comprising the inhibition, excitement, and parakinetic dimensions. Conclusions Overall, the results suggest that the BFCSI-SV and BFCRS-SV are valid and reliable tools for the diagnosis of catatonia, especially when using a cut-off score of 5 or higher for the BFCSI-SV and 7 or higher for the BFCRS-SV.

Agreement between Lea Symbols and Patti Pics visual acuity in children and adults

Background Patti Pics (PP) and Lea Symbols (LS) are commonly used by eye care practitioners worldwide. Although the relationship between the two tests is fairly well understood, the availability of different chart designs (single optotypes, multiple optotypes, multiple optotypes with crowding box) merits futher understanding. The purpose of this study is to explore the agreement between the acuity measures obtained with Patti Pics and Lea Symbols in children and adults and compare their performance with the Sloan Letter (SL) chart in adults. Methods Monocular visual acuity was obtained from ninety-three 3 to 5-year-old children using Patti Pics and Lea Symbols. Acuities were also obtained from 113 adults using the same tests under identical conditions. Acuity results obtained with the pediatric tests were compared with the gold-standard Sloan Letter chart in adults. The Bland-Altman method was implemented to compare the level of agreement between tests. Results Patti Pics yielded worse visual acuity than the Lea Symbols by approximately half a logMAR line in both children (mean difference: -0.07 ± 0.07 logMAR, p <0.01) and adults (Mean difference: -0.05 ± 0.06 logMAR, p <0.01). The 95% limits of agreement between Lea Symbol acuity and Patti pics acuity in children was ± 0.14 logMAR. Mean difference between the Sloan Letter chart and Lea Symbols acuity was not statistically significant (p = 0.08) in adults but the difference was statistically significant between PP and SL (p<0.001). The 95% limits of agreement between LS and SL and between PP and SL was ± 0.19 logMAR and ± 0.22 logMAR, respectively. Conclusion Patti Pics consistently underestimated visual acuity as compared to Lea Symbols both in children and adults although the differences were not clinically significant. The LS and PP did not yield clinically significant differences in acuities when compared with Sloan letters in adults. (AU)

Validity of the Maternal Antenatal Attachment Scale-Spanish Version for Mexican Pregnant Women / Validez de la Escala de Apego Prenatal Materno: versión en español para mujeres mexicanas embarazadas

During pregnancy, parents experiment emotions, thoughts, and behaviors related to their unborn child as precursors of attachment in the caretaker-infant dyad. The Maternal Antenatal Attachment Scale (MAAS) is an instrument that has shown adequate psychometric properties to evaluate this construct in developed countries. The aim of this study was to assess the reliability and concurrent validity of the Maternal Antenatal Attachment Scale-Spanish version for Mexican women (MAAS-Spanish version). A sample of 142 women in their third trimester of pregnancy who received care in a tertiary hospital was selected. The full scale of the MAAS-Spanish version obtained a Cronbach alpha of .79. A significant negative correlation was found between the global MAAS-Spanish version score (r = -.23, p ≤ .01) and the Postpartum Depression Predictors Inventory-Revised and depressive symptoms (r = -.36 , p ≤ .01). The translated and adapted scale has adequate internal consistency and concurrent validity to measure this construct in this population. ()AU)

Durante el embarazo, los padres experimentan emociones, pensamientos e ideas sobre su nonato relevantes en el estudio de precursores del apego en la díada cuidador-infante. La Escala de Apego Prenatal Materno (MAAS) es un instrumento que ha mostrado adecuadas propiedades psicométricas para evaluar este constructo en países desarrollados. El propósito de este estudio fue evaluar la confiabilidad y validez concurrente de dicha escala—versión en español para mujeres mexicanas (MAAS—versión en español). Se seleccionó a una muestra de 142 mujeres en tercer trimestre gestacional, que recibían atención en un hospital de tercer nivel. La escala total obtuvo un alfa de Cronbach de .79. Se evidenció una correlación negativa significativa de la puntuación global de la MAAS de r = -.23, (p ≤ .01) con la PDPI-R y de r = -.36, (p ≤ .01) con la sintomatología depresiva (EPDS). La escala traducida cuenta con una consistencia interna y validez concurrente adecuadas para medir este constructo en esta población. (AU)

Sensibilidad de escalas como pronóstico y necesidades paliativas en adultos mayores con enfermedad no oncológica / Sensitivity of scales as prognostic indicators and palliative needs in elderly patients with non-oncological diseases

Los cuidados paliativos tienen un enfoque multidisciplinario que mejora la calidad de vida. Tradicionalmente se centraron en pacientes oncológicos, sin embargo, pueden usarse en pacientes con cronicidad avanzada, en quienes existe falta de instrumentos validados para evaluar y determinar la atención paliativa. El objetivo de este estudio es describir la sensibilidad de las escalas NECPAL, PROFUND y Charlson para evaluar y determinar la mortalidad, y atención paliativa en adultos mayores con enfermedad crónica no oncológica mediante una revisión narrativa en las bases de datos BMJ, Elsevier, PubMed, HINARI y SciELO. Se incluyeron artículos originales, de revisión y ensayos clínicos en español e inglés, publicados en los últimos cinco años. La escala NECPAL permite identificar a los pacientes candidatos a cuidados paliativos y mide la prevalencia de personas con necesidad paliativa. El índice PROFUND es una puntuación pronóstica multidimensional que estima el riesgo de mortalidad a un año en pacientes con cronicidad avanzada. Como herramienta pronóstica evalúa el riesgo de mortalidad a treinta días. El índice de comorbilidad de Charlson, creado para predecir el riesgo de mortalidad a un año posterior a la hospitalización, es un excelente predictor en pacientes hospitalizados, no requiere pruebas de laboratorio y es aplicable en diversos escenarios clínicos

Palliative care has a multidisciplinary approach that improves the quality of life. Traditionally, palliative care focused on oncology patients; however, it can be applied to in-patients with advanced chronicity, for whom there is a lack of validated instruments to assess and determine palliative care. This study aims to describe the sensitivity of the NECPAL, PROFUND, and Charlson scales for assessing and determining mortality and palliative care in older adults with chronic non-oncologic disease through a narrative review in the BMJ, Elsevier, PubMed, HINARI, and SciELO databases. Original articles, review articles, and clinical trials in Spanish and English published in the last five years were included. The NECPAL tool identifies patients who are candidates for palliative care and measures the prevalence of palliative care needs. The PROFUND index is a multidimensional prognostic score that estimates the risk for one year mortality in patients with advanced chronicity. As a prognostic tool, it assesses 30-day mortality risk. The Charlson comorbidity index, created to predict one year mortality risk after hospitalization, is an excellent predictor in hospitalized patients, does not require laboratory tests, and is applicable in various clinical scenarios

Mechanical characteristics analysis and control algorithm for floating raft system with mass variation.

The ship floating raft system adopts the integrated design of large liquid tanks and rafts, which can optimize the arrangement in the cabin and increase the intermediate mass of the system to achieve efficient vibration isolation of equipment. One of the major challenges is that the change of liquid mass in the tank will cause displacement of the raft, which will change the modal characteristics of the system and affect the stability of the vibration isolation system performance. This paper establishes a mechanical analysis model of a floating raft system under time-varying liquid mass conditions. Taking a ship variable mass floating raft system as the research object, the effect of mass change on the characteristics of raft displacement, isolator load distribution, and modal frequency of the vibration isolation system is analyzed. The analysis shows that when the liquid tank goes from full load to no-load state, its mass change accounts for 40% of the total mass of the raft, which will cause a large displacement of the raft and change the low order modal frequency of the system, bringing the risk of equipment safety and vibration isolation performance degradation. Therefore, an adaptive variable load control method is proposed to realize the raft attitude balance and load equalization optimization under the variable mass condition of the floating raft air spring system. The test results show that the proposed control method can automatically adapt to the large mass gradual change from full load to no load of the liquid tank on the raft, and control the displacement of the raft structure from about 10 mm to 1.5 mm, which effectively ensures the stability of the air spring system performance.

Well-being at work scale (WBWS): Gathering empirical evidence from different interpretation strategies / Escala de bienestar en el trabajo (EBET): compilación de evidencia empírica de diferentes estrategias de interpretación

Well-being at work scale (WBWS) is a measure widely used in Brazil, composed of three dimen-sions (positive affects, negative affects and expressiveness/fulfillment) aligned with the field’s recent movement of junction of the two classical theoretical bases(hedonic and eudaimonic) that explain this phenomenon. Based on a cross-sectional survey involving 360 Brazilian work-ers, this study aimed to compare different models of interpreting the WBWS (including three one-dimensional proposals -composed by a single factor or second-order factor for WBW as-sessment -and one multidimensional proposal -composed by the three WBW factors singly). Each model was tested through exploratory and confirmatory factor analyzes, and then correla-tion analyzes between the models were run to allow their comparison. We concluded that the interpretation of WBWS from a single indicator is viable and more theoretically appropriate when it is intended to have a more integrated view about well-being at work. (AU)

La Escala de Bienestar en el Trabajo (EBET) es una medida ampliamente utilizada en Brasil, compuesta por tres dimensiones (afecto positivo, afecto negativo y expresividad/realización) alineadas con el movimiento reciente del campo de unión de las dos bases teóricas clásicas (hedónica y eudaimónica) que explican este fenómeno. Basado en una encuesta transversal que involucró a 360 trabajadores brasileños, este estudio tuvo como objetivo comparar diferentes modelos de interpretación de la EBET (incluidas tres propuestas unidimensionales, compuestas por un factor único o factor de segundo orden para la evaluación del BET; y una propuesta multidimensional compuesta por los tres factores BET individualmente). Cada modelo se probó a través de análisis factoriales exploratorios y confirmatorios, y luego se realizaron análisis de correlación entre los modelos para permitir su comparación. Concluimos que la interpretación de la EBET a partir de un solo indicador es viable y teóricamente más adecuada cuando se pre-tende tener una visión más integrada sobre el bienestar en el trabajo.

Accuracy of an endodontic rotary motor with integrated apex locator to determine the root canal length / Precisão de um motor rotatório endodôntico com localizador apical integrado para determinação do comprimento radicular

Aim: The purpose of this study was to evaluate the efficacy to determine the root canal length, in vitro,of both the electronic apex locator (M2) and the autostop (AS - M3) functions of the Endus Duo Gnatus endodontic motor (Gnatus, São Paulo, SP, Brazil). Methods: Thirty extracted human single-rooted premolars had their root canal lengths (TLs) up to the apical foramen determined using the Endus Duo Gnatus in two ways: (1) In the stainless steel (SS) control group, the measurement was obtained using a stainless steel hand instrument with the electronic locator mode (M2 function) connected to a stainless-steel hand instrument (K-file #15). In the NiTi rotary instrument (NiTi RI) intervention group, the measurement was obtained during the instrumentation (M3 function) of the root canals with a nickel-titanium rotary instrument (Hyflex CM: Coltene Whaledent, Cuyahoga Falls, OH, USA), size 25/.06. The NiTi manually used instrument (NiTi MUI) Intervention group performed the measurement in locator mode using a Hyflex instrument, placed to true length manually. Statistical analysis was performed using ANOVA followed by the Tukey post-hoc test with a significance level of p < 0.05. Results: The true mean length and standard deviation (SD) of the standardized root canals were 18.40 ± 2.14mm, while the mean lengths and standard deviations (SD) were 18.29 ± 1.89mm, 18.22 ± 1.85mm, and 17.24 ± 2.09mm for the SS, NiTi RI, and NiTi MUI groups, respectively. However, data from the NiTi MUI Intervention group indicated shorter root canal lengths when compared to the SS control group and the NiTi RI Intervention group values, and were significantly shorter than the true canal length (p < 0.001). Conclusions:The use of the motor in NiTi RI Intervention group showed acceptable results. However, the NiTi MUI Intervention group resulted in unacceptable short measurements.

Objetivo: O objetivo deste estudo foi avaliar a eficácia na determinação do comprimento do canal radicular, in vitro, das funções localizador eletrônico foraminal (M2) e auto-parada durante a instrumentação (M3) do motor endodôntico Endus Duo Gnatus ( Gnatus, São Paulo, SP, Brasil). Métodos: Trinta pré-molares humanos uniradiculares extraídos tiveram seus comprimentos de canais radiculares (CRTs) até o forame apical determinados usando o Endus Duo Gnatus de duas maneiras: (1) No grupo controle de aço inoxidável (SS), a medida foi obtida usando um instrumento manual de aço inoxidável com modo de localização eletrônica foraminal (função M2) conectado a um instrumento manual de aço inoxidável (lima tipo K #15). No grupo intervenção instrumento rotatório NiTi (NiTi RI), a medida foi obtida durante a instrumentação (função M3) dos canais radiculares com instrumento rotatório de níquel-titânio (Hyflex CM: Coltene Whaledent, Cuyahoga Falls, OH, EUA), tamanho 25/.06. O grupo de intervenção NiTi instrumento usado manualmente (NiTi MUI) realizou a medição no modo localizador foraminal usando um instrumento Hyflex, colocado manualmente no comprimento real do dente. A análise estatística foi realizada por meio de ANOVA seguida do teste post-hoc de Tukey com nível de significância de p < 0,05. Resultados: Os comprimentos reais médios dos dentes e desvios-padrão (DP) dos canais radiculares padronizados foram 18,40 ± 2,14 mm, enquanto os comprimentos médios e desvios- padrão (DP) foram 18,29 ± 1,89 mm, 18,22 ± 1,85 mm e 17,24 ± 2,09 mm para os grupos SS, NiTi RI e NiTi MUI, respectivamente. No entanto, os dados do grupo de intervenção NiTi MUI indicaram comprimentos de canais radiculares mais curtos quando comparados aos valores do grupo controle SS e do grupo de intervenção NiTi RI, e foram significativamente mais curtos que o comprimento real do canal (p < 0,001). Conclusões: A utilização do motor no grupo Intervenção NiTi RI apresentou resultados aceitáveis. No entanto, o grupo de intervenção NiTi MUI resultou em medições curtas inaceitáveis.

Attitudes and practices of travelers regarding COVID-19 vaccine and adverse reactions

Objective.In the context of the global COVID-19 pandemic, COVID-19 vaccines were made available to different countries. This study aimed to assess travelers' attitudes and practices toward the COVID vaccine and adverse events. Methods. A survey was conducted using a questionnaire from April 1 to June 30, 2021, among travelers who came for their COVID-19 test at the Institut Pasteur of Côte d'Ivoire.Results. A total of 527 travelers agreed to participate in this study, including 336 men and 161 women. Overall, 26% of respondents had already received their COVID-19 vaccine, while 76% of respondents responded they did not want to be vaccinated. The age of those most vaccinated (116) ranged from 25 to 64 years with a small proportion for those over 65 years (0.8%). Travelers (41) to France were the most vaccinated. All vaccinated persons (135) had a high level of education and were either Christian (89 persons), Muslim (45 persons) or animist (1 person). Adverse events related to the COVID vaccination were reported in seven individuals. These included muscle pain, fever and nausea. Conclusion.Negative attitudes towards vaccines are a major public health concern. In view of these results, for awareness raising, vaccination campaign may be focused on youthand people over 65 years of age. Public health messages containing information about vaccine safety should be tailored to address this vaccine hesitancy

Correlación y concordancia del índice de masa corporal con el perímetro abdominal y el índice cintura-talla en adultos peruanos de 18 a 59 años / Correlation and concordance between the body mass index and abdominal perimeter with the waist-to-height ratio in peruvian adults aged 18 to 59 years

Objetivos. Determinar la correlación y concordancia diagnóstica del índice de masa corporal (IMC), con el perímetro abdominal (PA) y el índice cintura-talla (ICT). Materiales y métodos. Se realizó un estudio descriptivo, transversal, de datos secundarios usando las bases de datos antropométricos de la Encuesta Vigilancia Alimentaria y Nutricional por Etapas de Vida Adulto de 18 a 59 años 2017-2018 que incluyó 1084 personas para los dominios geográficos Lima Metropolitana, resto urbano y rural. Se estimaron las prevalencias de obesidad según IMC, PA e ICT y se empleó el coeficiente de correlación de Lin y Kappa de Cohen para determinar la correlación y concordancia entre las tres mediciones antropométricas. Resultados. Según los criterios de IMC, PA e ICT las prevalencias de obesidad fueron de 26,8%, 50,4% y 85,4%, respectivamente; las prevalencias fueron mayores en mujeres y en mayores de 30 años. La correlación entre IMC vs. PA e IMC vs. ICT fue pobre y de PA con ICT fue moderada, con diferencias entre hombres y mujeres. Además, la concordancia entre IMC y PA fue aceptable, mientras que la concordancia entre IMC vs. ICT fue leve. Conclusiones . Los resultados de la correlación y concordancia son limitados y sugieren que no son medidas intercambiables, por lo que es necesario evaluar la suficiencia de emplear solo IMC para el diagnóstico de obesidad en el Perú. Esta limitada correlación y concordancia se refleja en las diferentes proporciones de obesidad que oscilan entre 26,8% a 85,4% al aplicar los tres criterios.

Objective. To determine the correlation and diagnostic agreement of body mass index (BMI) and abdominal perimeter (AP) with the waist-to-height ratio (WHtR). Materials and methods. A descriptive, cross-sectional, secondary data study was conducted using the anthropometric databases of the Food and Nutrition Surveillance Survey by Adult Life Stages from 18 to 59 years old, 2017-2018, which included 1084 individuals for the geographic domains of Metropolitan Lima, other urban areas, and rural regions. The prevalence of obesity was estimated according to BMI, AP and WHtR. Lin's correlation coefficient and Cohen's Kappa were used to determine the correlation and agreement between the three anthropometric measurements. Results. According to the BMI, AP, and WHtR criteria, the prevalence of obesity was 26.8%, 50.4% and 85.4%, respectively; the prevalence was higher in women and in those over 30 years of age. The correlation between BMI and AP, as well as between BMI and WHtR was poor; it was moderate between AP and WHtR, with differences between men and women. Furthermore, the agreement between BMI and AP was acceptable, whereas the agreement between BMI vs. WHtR was mild. Conclusions. The results regarding correlation and agreement are limited and suggest that they are not interchangeable measures, so it is necessary to evaluate the adequacy of using BMI alone for the diagnosis of obesity in Peru. The limited correlation and agreement was reflected in the different proportions of obesity that range from 26.8% to 85.4% when applying the three criteria.

The MOVIE model: Assessing movie preferences and personality correlates / O modelo MOVIE: Avaliando a preferência por filmes e os correlatos com personalidade / El modelo MOVIE: Evaluando la preferencia por películas y los correlatos con la personalidade

Watching movies is a common fun form, generating billions of dollars annually. However, few studies explored individual differences that predict movie preferences, even considering that they reflect some personality features. One of the main limitations in the area is the lack of measures and models that operationalize the structure of movie preferences. Thus, in the present study, we proposed and tested a five-factor measure to assess movie preferences: the MOVIE (Melodrama, cOmic, Violent, Imaginative, and Exciting) model. The structure presented acceptable psychometric parameters besides meaningful associations with personality traits. These results, even with low magnitudes, show that the process of choosing a movie or content may reflect specific personality traits and reinforce the role that personality can play in the real world.

Assistir a filmes é uma forma comum de diversão, gerando bilhões de dólares por ano a indústria do cinema. No entanto, poucos estudos exploraram as diferenças individuais que predizem as preferências por filmes, mesmo considerando que estas refletem algumas características da personalidade. Uma das principais limitações da área é a falta de medidas e modelos que operacionalizem a estrutura de preferências cinematográficas. Assim, no presente estudo, propusemos e testamos uma medida de cinco fatores para avaliar as preferências de filmes: o modelo MOVIE (Melodrama, cOmic, Violent, Imaginative e Exciting). Tal estrutura apresentou parâmetros psicométricos aceitáveis, além de associações significativas com traços de personalidade. Esses resultados, mesmo com magnitudes baixas, mostram que o processo de escolha de um filme ou conteúdo pode refletir traços específicos de personalidade e reforçar o papel que a personalidade pode desempenhar no mundo real.

Ver películas es una forma común de diversión que genera millones de dólares al año. Sin embargo, pocos estudios están considerando las diferencias individuales que predicen las preferencias cinematográficas, incluso si reflejan algunos rasgos de personalidad. Una de las principales limitaciones en el área es la falta de medidas y modelos que operacionalicen la estructura de las preferencias cinematográficas. Por lo tanto, en el presente estudio, propusimos y probamos una medida de cinco factores para evaluar las preferencias cinematográficas: el modelo MOVIE (Melodrama, cOmic, Violent, Imaginative, and Exciting). Dicha estructura presentó parámetros psicométricos aceptables, además de asociaciones significativas con los rasgos de personalidad. Estos resultados, incluso con magnitudes bajas, muestran que el proceso de elección de una película o contenido puede reflejar rasgos de personalidad específicos y reforzar el papel que la personalidad puede desempeñar en el mundo real.

Concordancia entre criterios de clasificación nutricional en adultos mayores, Colombia / Accordance between different nutritional classification criteria in older adults, Colombia

Introducción: El envejecimiento es un proceso irreversible que genera aumento permanente de la población de 60 o más años. Esta población vulnerable, vive en condiciones de discapacidad, abandono, falta de atención y presenta enfermedades asociadas con su estado nutricional, esto hace necesario determinarlo de forma adecuada. Objetivo: Analizar la concordancia entre diferentes criterios de clasificación nutricional según el Índice de Masa Corporal, a partir de una encuesta poblacional de envejecimiento, Colombia 2015. Material y métodos: Se utilizaron cuatro criterios y la concordancia entre las categorías del estado nutricional. Se calculó con los índices de Kappa directo y ponderado. Resultados: Las concordancias fueron moderadas y buenas, la menor proporción de bajo peso (3,4%) se obtuvo utilizando el criterio Organización Mundial de la Salud y la más alta (22,6%) con Organización Panamericana de Salud (p<0,05). El bajo peso se incrementa a medida que aumenta la edad, mientras el exceso de peso disminuye. Conclusiones: La clasificación nutricional cambia según el criterio y puntos de corte, el de la Sociedad Española de Nutrición Parenteral y Enteral, tuvo la mayor concordancia comparado con el de la Organización Mundial de la Salud y mejor capacidad para detectar deficiencia nutricional en la población adulta mayor.

Introduction: Aging is an irreversible process that generates a permanent increase in the 60 and older population. This vulnerable population lives in conditions of disability, neglect, lack of attention, and they present with illnesses related to their nutritional status, which is why it is necessary to understand it fully. Objective: To analyze the accordance between different criteria of nutritional classification according to the Body Mass Index, using an aging population survey, Colombia 2015. Materials and methods: Four criteria were used as well as accordance between categories of nutritional status. Direct and weighted Kappa indices were calculated. Results: The accordance was moderate and good, the lowest proportion of low weight (3.4%) was obtained using the World Health Organization criteria and the highest (22.6%) with the Pan American Health Organization (p<0.05). Low weight is increased as one ages, while excessive weight decreases. Conclusions: Nutritional classification changes depending on the criteria and cut-off points. The criteria of the Spanish Society of Parenteral and Enteral Nutrition had the highest accordance with the World Health Organization and the best capacity in detecting nutritional deficiency in the older adult population.

Validación de la versión española de la Escala de funcionamiento breve (FAST) en pacientes diagnosticados de esquizofrenia / Validity of the Functioning Assessment Short Tests (FAST), in patients with schizophrenia

Introducción: El deterioro funcional es una de las principales características del curso de la esquizofrenia e implica un gran impacto en la calidad de vida del paciente. La Escala de funcionamiento breve (FAST), validada originalmente en trastorno bipolar, también ha sido validada para su aplicación en otros trastornos mentales, aunque solo encontramos un estudio sobre la fiabilidad y validez de la versión brasileña en esquizofrenia. El propósito de este estudio fue analizar las propiedades psicométricas de la versión española de la FAST en pacientes diagnosticados de esquizofrenia.Material y métodos: Un total de 226 pacientes con diagnóstico de esquizofrenia fueron evaluados, cumplimentando la FAST, la GAF y la Escala de requisitos de autocuidado (ERA). Se analizaron las propiedades de la escala en términos de consistencia interna, concordancia interobservador y fiabilidad test-retest. Se analizó también la validez convergente con las escalas GAF y ERA, y la validez de constructo mediante un análisis factorial confirmatorio.Resultados:Para el total del cuestionario los resultados mostraron una elevada consistencia interna (Cronbach's Alpha de 0,87), así como una buena concordancia interobservador (CCI=0,86) y test-retest (CCI=0,77). La validez concurrente con la escala GAF fue discreta (r=–0,32; p<0,001) y con la escala ERA moderada (r=0,50; p<0,001). El análisis factorial confirmatorio mostró una estructura interna que se ajustaba a los 6 factores de la escala original, con un buen nivel de saturación de los ítems para cada factor.Conclusiones: La escala FAST mostró buenas propiedades psicométricas en términos de fiabilidad y validez en su versión española para su aplicación en pacientes con esquizofrenia. Se puede considerar una buena herramienta para evaluar diferentes áreas del deterioro funcional en la práctica clínica y en investigación. (AU)

Introduction: Functional impairment in schizophrenia is one of the main features of the disorder and implies a great impact on the patient's quality of life. The brief functioning assessment scale (FAST), originally validated in bipolar disorder, has also been validated for its application in other mental disorders. However, we only found one study on the reliability and validity of the Brazilian version in schizophrenia. The purpose of this study was to analyze the psychometric properties of the Spanish version of the FAST in patients diagnosed with schizophrenia.Material and methods: A total of 226 patients with a diagnosis of schizophrenia were evaluated by mean the FAST, the GAF and the self-care requirements scale (ERA). Scale properties were analyzed in terms of internal consistency, inter-observer agreement and test–retest reliability. Convergent validity with the GAF and ERA scales was also analyzed, as well as construct validity by means of a Confirmatory Factor Analysis (CFA).Results: For the total scale, the results showed high internal consistency (Cronbach's Alpha of .87), as well as good inter-observer (ICC=.86) and test–retest (ICC=.77) agreement. Concurrent validity with the GAF scale was discrete (r=−.32; P<.001) and with the ERA scale was moderate (r=.50; P<.001). CFA showed an internal structure that matched the six factors proposed by the original scale, with a good level of item saturation for each factor.Conclusions: The FAST scale showed good psychometric properties in terms of reliability and validity in its Spanish version for its application in patients with schizophrenia. It can be considered as a good tool to assess different areas of functional impairment in clinical practice and research. (AU)

Validación y adaptación española de la Escala de Actitudes Estigmatizadoras hacia la Salud Mental entre Iguales (Peer Mental Health Stigmatization Scale, PMHSS-24) / Spanish adaptation and validation of the Peer Mental Health Stigmatization Scale (PMHSS-24)

Introducción: En la actualidad, existe un creciente interés por las intervenciones con adolescentes encaminadas a la reducción del estigma hacia las personas con problemas de salud mental. Desafortunadamente, el número de escalas disponibles en castellano para evaluar el estigma en estas edades es reducido. El presente trabajo tiene por objetivo adaptar y validar en población española la Escala de Actitudes Estigmatizadoras hacia la Salud Mental entre Iguales (PMHSS-24). Material y métodos: Participaron 443 adolescentes (46,6% mujeres y 53,7% hombres) de entre 13 y 17 años (Medad=14,64; DE=0,83) alumnos de 3.° y 4.° de Educación Secundaria Obligatoria. Se calculó la consistencia interna de la prueba, se realizó un análisis factorial exploratorio (AFE) con la mitad de la muestra y otro confirmatorio (AFC) con la otra mitad, y se halló la invarianza de medición de la escala a través del sexo. Resultados: El AFE arrojó una estructura de 2factores para la escala negativa (53% de la varianza explicada) y otros 2para la positiva (62% de la varianza explicada). El AFC corroboró la estructura factorial con adecuados indicadores de bondad de ajuste (CFI>0,95; NNFI>0,95; SRMR <0,08; RMSEA <0,08). Las cargas factoriales oscilaron entre 0,49 y 0,89, con una correlación entre factores r=0,53 y 0,45. Ambas subescalas exhibieron valores de αóptimos (negativa 0,94 y positiva 0,81). La escala fue invariante entre sexos. Conclusiones: El PMHSS-24 puede ser un instrumento útil para el cribado inicial de los estereotipos que exhiben los adolescentes hacia las personas con dificultades emocionales. (AU)

Introduction: There is currently a growing interest in interventions aimed at the reduction of stigma towards people with emotional difficulties in adolescents. Unfortunately, the number of scales available in Spanish to assess stigma at these ages is limited. This paper aims to adapt and validate the scale of stigmatizing attitudes towards mental health among peers (Peer Mental Health Stigmatization Scale PMHSS-24). Material and methods: A total of 443 adolescents (46.6% female and 53.7% male) between 13 and 17 years of age participated (Mage=14.64; SD=.83) in the 3rd and 4th grades of Obligatory Secondary Education. The internal consistency of the test was calculated, an exploratory factorial analysis (EFA) was performed with half of the sample and a confirmatory one (CFA) with the other half, and the invariance of measurement of the scale through sex was found. Results: The EFA showed a two-factor structure for the negative scale (53% of the variance explained) and another 2for the positive scale (62% of the variance explained). The CFA corroborated the factor structure with appropriate goodness-of-fit indicators (CFI>.95; NNFI>.95, SRMR<.08, RMSEA<.08). Factor loads ranged from .49 to .89, with α factor correlation between r=.53 and .45. Both subscales exhibited optimal alpha values (negative .94 and positive .81). The scale was invariant between the sexes. Conclusions: The data suggest that PMHSS-24 may be a useful scale for the initial screening of the stereotypes exhibited by adolescents toward people with mental illness. (AU)

Escala pediátrica de disfunción multiorgánica secuencial: validación en pacientes pediátricos graves con leucemia linfoide aguda / Pediatric sequential multiorgan dysfunction scale: validation in critical pediatric patients with acute lymphocytic leukemia

Introducción: Los pacientes que ingresan a la unidad de cuidados intensivos pediátricos son aquellos con alto riesgo de mortalidad que pueden presentar síndrome de disfunción orgánica múltiple. Los pacientes que padecen leucemia linfoide aguda forman parte de este grupo. Objetivos: Validar la escala pediátrica de evaluación del fallo multiorgánico secuencial (pSOFA) en pacientes cubanos graves con diagnóstico de leucemia linfoide aguda. Métodos: Se realizó un estudio observacional, prospectivo, multicéntrico, en unidades de cuidados intensivos de hospitales cubanos con 92 pacientes y 184 ingresos. Se calcularon las puntuaciones de las escalas de disfunción multiorgánica secuencial, riesgo de mortalidad e índice de mortalidad pediátrica, y se evaluó la presencia de disfunción orgánica en las primeras 24 h y a las 48 h. Resultados: La puntuación pSOFA fue mayor en los no supervivientes (p < 0,001) y la mortalidad se incrementó de modo progresivo en los subgrupos con las puntuaciones pSOFA más altas. El análisis de las curvas de las características operativas del receptor (ROC) mostró que el área bajo la curva (AUC) para la predicción de la mortalidad con la puntuación pSOFA fue de 0,89, comparado con 0,84 y 0,79 con las escalas PRISM-3 y PIM-2, respectivamente. Conclusiones: La escala pSOFA mostró ser útil para establecer los criterios disfunción orgánica y su especificidad en el riesgo de mortalidad en los pacientes pediátricos cubanos críticos con diagnóstico de leucemia linfoide aguda(AU)

Introduction: Patients admitted to the pediatric intensive care unit (PICU) are those with a high risk of mortality who may present multiple organ dysfunction syndrome. Patients with acute lymphoid leukemia are part of this group. Objectives: To validate the pediatric sequential multi-organ failure assessment scale (pSOFA) in severe Cuban patients diagnosed with acute lymphoid leukemia. Methods: An observational, prospective, multicenter study was carried out in intensive care units of Cuban hospitals with 92 patients and 184 admissions. The scores of the sequential multiple organ dysfunction, mortality risk and pediatric mortality index scales were calculated, and the presence of organ dysfunction was evaluated in the first 24 hours and at 48 hours. Results: The pSOFA score was higher in non-survivors (p <0.001) and mortality progressively increased in the subgroups with the highest pSOFA scores. The analysis of the receiver operating characteristics (ROC) curves showed that the area under the curve (AUC) for the prediction of mortality with the pSOFA score was 0.89, compared to 0.84 and 0.79 with the PRISM-3 and PIM-2 scales, respectively. Conclusions: The pSOFA scale proved useful to establish the criteria for organ dysfunction and its specificity in the risk of mortality in critical Cuban pediatric patients diagnosed with acute lymphoid leukemia(AU)

Validation of the Children’s Inventory of Anger (ChIA) with a Mexican sample / Validación del Cuestionario del Enojo para Niños (ChIA) con una muestra mexicana

The Children’s Inventory of Anger (ChIA) is a self-report measure that assesses the level of anger experienced by children and youth. Anger is asignificant predictor of aggression, peer relationships difficulties and antisocial behavior; therefore, is crucial to have a valid and reliable measure toevaluate it. The purpose of this study was to validate the ChIA for the Mexican children (ChIA-M). Participants were 638 students (M = 9.8 years; SD= 1.51), 49% were females from primary and secondary Mexican public schools. The exploratory factor analysis supported the four-factor structurewith a shared variance of 47.60%, but a different distribution of items. The confirmatory factor analysis indicated the model to be an acceptable fitwith the data χ 2 (338) = 1089.75, p ≤ .001, NFI = .82; IFI = .907, CFI = .906, RMSEA = .047. Good internal consistency was obtained for Totalscore α = .94 and subscales: Frustration α = .90, Aggression α = .88 , Peer Relationships α = .76 and Authority Relations α = .81. Convergentand divergent validity was supported through positive and significant correlations with the Anger Inventory for Mexican Children and the negligiblecorrelations with the Children Questionnaire of Positive Emotions. Results suggest that the Spanish version of the ChIA for Mexican population isa valid and reliable measure of child anger. However, attention should be paid to the cultural differences related to the experience of anger. Furtherresearch should continue evaluating the ChIA with clinical samples and children from different ages and regions in Mexico. (AU)

Se sugiere seguir investigando el ChIAcon muestras clínicas y niños de diferentes edades y regiones de México. (AU)

Machine Learning Identifies Digital Phenotyping Measures Most Relevant to Negative Symptoms in Psychotic Disorders: Implications for Clinical Trials.

BACKGROUND: Digital phenotyping has been proposed as a novel assessment tool for clinical trials targeting negative symptoms in psychotic disorders (PDs). However, it is unclear which digital phenotyping measurements are most appropriate for this purpose. AIMS: Machine learning was used to address this gap in the literature and determine whether: (1) diagnostic status could be classified from digital phenotyping measures relevant to negative symptoms and (2) the 5 negative symptom domains (anhedonia, avolition, asociality, alogia, and blunted affect) were differentially classified by active and passive digital phenotyping variables. METHODS: Participants included 52 outpatients with a PD and 55 healthy controls (CN) who completed 6 days of active (ecological momentary assessment surveys) and passive (geolocation, accelerometry) digital phenotyping data along with clinical ratings of negative symptoms. RESULTS: Machine learning algorithms classifying the presence of a PD diagnosis yielded 80% accuracy for cross-validation in H2O AutoML and 79% test accuracy in the Recursive Feature Elimination with Cross Validation feature selection model. Models classifying the presence vs absence of clinically significant elevations on each of the 5 negative symptom domains ranged in test accuracy from 73% to 91%. A few active and passive features were highly predictive of all 5 negative symptom domains; however, there were also unique predictors for each domain. CONCLUSIONS: These findings suggest that negative symptoms can be modeled from digital phenotyping data recorded in situ. Implications for selecting the most appropriate digital phenotyping variables for use as outcome measures in clinical trials targeting negative symptoms are discussed.

Overlooked subclinical portal hypertension in non-cirrhotic NAFLD: Is it real and how to measure it?

Clinical and experimental advances related to the detection, magnitude and pathobiology of subclinical portal hypertension in non-alcoholic fatty liver disease (NAFLD), primarily observed in the presence of non-alcoholic steatohepatitis (NASH), prompt us to revisit current disease paradigms. Hepatic venous pressure gradient (HVPG) has been reported to underestimate portal pressure in NASH-related cirrhosis, while inaccuracy is more likely in non-cirrhotic livers, indicating a potential need for new and preferably non-invasive methods of measurement. Although clinically significant portal hypertension (HVPG ≥10 mmHg) retains its prognostic significance in NASH, subclinical portal hypertension (HVPG 6.0-9.5 mmHg) has been repeatedly detected in patients with NAFLD in the absence of cirrhosis or even significant fibrosis whereas the impact of these findings on disease outcomes remains unclear. Mechanocrine signalling pathways in various types of liver cell reveal a molecular basis for the adverse effects of subclinical portal hypertension and suggest a bidirectional relationship between portal pressure and fibrosis. These findings may guide efforts to improve risk assessment and identify novel therapeutic targets in NAFLD.
