Translation and validity of the Multidimensional Individual and Interpersonal Resilience Measure.

OBJECTIVE: to translate, culturally adapt and validate the Multidimensional Individual and Interpersonal Resilience Measure to Brazilian Portuguese. METHOD: after initial translation, the pre-final version underwent rigorous cultural adaptation procedures. As a result, the final adapted version was submitted to a validity study. RESULTS: adaptation procedures provided equivalence between the pre-final and the original versions in semantic, idiomatic, experiential and conceptual terms. A total of 187 older adults were included in the validity study. Exploratory factorial analysis (EFA) generated a model of five factors ((RMSEA = 0.030; TLI = 0.959; X2 = 151.590 p> 0.05). Final version showed adequate consistency (Cronbach's α = 0.705) and test-retest reliability (ICC=0.835). No statistically significant correlation was found between resilience and sociodemographic and epidemiological variables assessed in this study. CONCLUSION: EMRII-BR is a valid and reliable instrument for measuring resilience in Brazilian older adults.

Potential Biomarkers of impulsivity in mild traumatic brain injury: A pilot study.

Very few studies have investigated cognition and impulsivity following mild traumatic brain injury (mTBI) in the general population. Furthermore, the neurobiological mechanisms underlying post-TBI neurobehavioral syndromes are complex and remain to be fully clarified. Herein, we took advantage of machine learning based-modeling to investigate potential biomarkers of mTBI-associated impulsivity. Twenty-one mTBI patients were assessed within one-month post-TBI and their data were compared to 19 healthy controls on measures of impulsivity (Barratt Impulsiveness Scale - BIS), executive functioning, episodic memory, self-report cognitive failures and blood biomarkers of inflammation, vascular and neuronal damage. mTBI patients were significantly more impulsive than controls in BIS total and subscales. Serum levels of sCD40L, Cathepsin D, IL-4, Neuropilin-1, IFN-α2, and Copeptin were associated with impulsivity in mTBI patients. Besides showing that mTBI are associated with impulsivity in non-military people, we unveiled different pathophysiological pathways potentially implicated in mTBI-related impulsivity.

RESUMO Objetivo: traduzir, adaptar culturalmente e validar o Multidimensional Individual and Interpersonal Resilience Measure para o português brasileiro. Método: após a tradução inicial, a versão pré-final passou por rigorosos procedimentos de adaptação cultural. Como resultado, a versão final adaptada foi submetida a um estudo de validade. Resultados: os procedimentos de adaptação proporcionaram equivalência entre as versões pré-final e original em termos semânticos, idiomáticos, experienciais e conceituais. Um total de 187 idosos foram incluídos no estudo de validade. A análise fatorial exploratória (AFE) gerou um modelo de cinco fatores ((RMSEA = 0,030; TLI = 0,959; X2 = 151,590 p> 0,05). A versão final apresentou consistência adequada (α de Cronbach = 0,705) e confiabilidade teste-reteste (ICC=0,835). Não foi encontrada correlação estatisticamente significativa entre a resiliência e as variáveis sociodemográficas e epidemiológicas avaliadas neste estudo. Conclusão: o EMRII-BR é um instrumento válido e confiável para mensurar a resiliência em idosos brasileiros.

RESUMEN Objetivo: traducir, adaptar culturalmente y validar el Multidimensional Individual and Interpersonal Resilience Measure para el portugués brasileño. Método: después de la traducción inicial, la versión pre-final pasó por rigurosos procedimientos de adaptación cultural. Como resultado, la versión final adaptada fue sometida a un estudio de validez. Resultados: los procedimientos de adaptación proporcionaron equivalencia entre las versiones pre-final y original en términos semánticos, idiomáticos, experienciales y conceptuales. Un total de 187 ancianos fueron incluidos en el estudio de validez. El análisis factorial exploratorio (AFE) generó un modelo de cinco factores ((RMSEA = 0,030; TLI = 0,959; X2 = 151,590 p> 0,05). La versión final mostró adecuada consistencia (α de Cronbach = 0,705) y confiabilidad prueba-reprueba (ICC=0,835). No se encontró correlación estadísticamente significativa entre la resiliencia y las variables sociodemográficas y epidemiológicas evaluadas en este estudio. Conclusión: EMRII-BR es un instrumento válido y confiable para medir la resiliencia en ancianos brasileños.

Comparing middle latency response with and without music.

UNLABELLED: Auditory evoked potentials can be used as a tool to investigate the central nervous system and structures that can be activated by auditory stimulation. There are few studies correlating the Middle Latency Response with different types of auditory stimulation, which led us to undergo this study. AIM: to verify The Middle Latency Response (MLR) in normal hearing adults when stimulated by clicks and music in the contralateral ear. STUDY DESIGN: a cross-sectional contemporary cohort. METHOD: MLR was carried out on 10 normal hearing subjects using bilateral clicks (70 dB nNA) and music in the contralateral ear. We measured and compared the amplitude and latency of the Pa wave with clicks and clicks and music. We compared the amplitude and latency of the electrodes in sites C3 and C4 for both ears with and without music. RESULTS: All subjects had MLR within normal limits for both amplitudes and latencies bilaterally. Stimuli with music and clicks revealed a reduction of the amplitude in the contralateral ear with the music stimulus in all electrode sites although this reduction was not statistically significant. CONCLUSION: We conclude that music in the contralateral ear reduces the amplitude of the Pa wave of the MLR.
