The NeuroBel: A Screening Test for Verbal Language Impairment in Spanish-Speaking Elderly People With Cognitive Decline.

PURPOSE: The NeuroBel is a short test that can detect cognitive decline using language tasks. This study replicated previous research using larger clinical samples from three Spanish-speaking countries. METHOD: Eight tasks were used to analyze verbal language functioning using a psycholinguistic approach. A total of 232 elderly, monolingual Spanish speakers from Spain, Cuba, and Colombia participated in this study. Of these, 76 had Alzheimer's disease (AD) in the initial phase, 75 had mild cognitive impairment (MCI), and 81 did not exhibit cognitive impairment (healthy controls). RESULTS: Significant differences were observed among the three clinical groups. The participants with AD and the participants with MCI had significantly lower NeuroBel scores than the control group on most of the tasks. However, repetition (in AD vs. MCI) and auditory lexical decision (in MCI vs. control) tasks were not significant in Tukey's post hoc tests. Discriminant analysis showed that 80.6% of the participants were correctly classified into the original groups and revealed the tasks that were the best and worst for differentiating among groups. The receiver-operating characteristic curves showed high sensitivity for AD and MCI. The area under the curve was .97 in the contrast of AD versus MCI + controls, .96 in the determination of overall cognitive decline (AD + MCI vs. controls), and .93 in the contrast of MCI and control groups. CONCLUSION: This study confirmed that the NeuroBel is a suitable test for detecting cognitive decline based on language impairment in Spanish-speaking elderly people.

Voice feminization in male-to-female transgendered clients after Wendler's glottoplasty with vs. without voice therapy support.

The objective of this study was to evaluate the medium-term results of Wendler's glottoplasty surgery (WG) and the effects of post-operative voice therapy in a group of male-to-female transsexuals. This is a retrospective study of 18 transsexuals who voluntarily underwent WG between 2010 and 2014 at a single hospital. Ten of the subjects underwent an additional voice therapy training. The group was assessed pre- vs. post-treatments with a limited battery of measures consisting of fundamental frequency (Fo), maximum phonation time, the TSEQ transgender self-assessment questionnaire, and perceptual assessment of the voice (Visual Analog Scale and a simplified version of the classical Hirano-GRBAS scale) by inter-rater agreement. The surgical procedure consisted of a de-epithelialization of the anterior third of both vocal folds; this area was sutured, and the surface of both vocal folds was vaporized with a laser diode. The results showed a significant increase in vocal tone and feminization of voice in all participants, including a significant increase in Fo 12 months after treatment. Significant improvements were also shown in other evaluated measures, such as self-reported satisfaction and the degree of feminization of the voice. However, no improvements in maximum phonation time were observed. The use of voice therapy appears decisive for optimal improvement of this class of patients. WG applied appropriately by well-trained hands is thus a very effective and less traumatic procedure than other techniques that aim for an acceptable feminization of the voice in MtoF transgendered clients.

Trastorno Específico del Lenguaje: Marcadores psicolingüísticos en semántica y pragmática en niños españoles / Specific Language Impairment: Markers into semantic and pragmatic areas in Spanish-speaking children

El objetivo del estudio fue determinar qué marcadores semánticos y pragmáticos sirven para discriminar mejor a niños con Trastorno Específico del Lenguaje (TEL) de niños con desarrollo normal del lenguaje. El estudio analiza los resultados de 31 niños hispanohablantes con TEL en una batería de 9 tareas psicolingüísticas. Sus resultados se compararon con el de dos subgrupos control: uno de niños emparejados en edad cronológica (CE) y otro de niños emparejados en edad lingüística (CL). Los datos mostraron que el grupo TEL realizó peor que el grupo CE la mayoría de las tareas (8/9). Sin embargo, el grupo TEL sólo fue significativamente peor que el CL en una de las tareas. Un primer Análisis Discriminante TEL vs CA estableció una función canónica con una Sensibilidad de 93,5% y una Especificidad de 87.1%. Un segundo Análisis Discriminante TEL vs CL estableció una función canónica con Sensibilidad de 77,4% y Especificidad de sólo 54.8%. Una tarea semántica (Definición de palabras) y una tarea pragmática (Lenguaje contextual) parecen ser las mejores tareas para establecer un perfil del TEL en estas áreas. Estos resultados se discuten a la luz de las implicaciones que pueden tener para el diagnóstico clínico y la psicopatología del lenguaje

The aim of this study is to determine which semantics and pragmatics markers best discriminate Spanish-speaking children with Specific Language Impairment (SLI) from children with typical language development. This study analyzes the performance of 31 Spanish-speaking children with SLI on a battery of 9 psycholinguistic tasks. The performance of the SLI children was compared with that of two subgroups of controls: aged-matched (CA) and linguistically matched (CL). The data show that the SLI group performed more poorly than the CA subgroup on most of the tasks (8/9). However, the SLI group performance only was significantly worse that of the CL subgroup on one of the tasks. A first Discriminant Analysis SLI vs CA established canonical function with Sensitivity 93,5% and Specificity 87,1%. A second Discriminant Analysis SLI vs CL identified a canonical function with Sensitivity 77,4% and Specificity only 54,8%. One semantic task (Definition of words) and another pragmatic task (Scene language) appear to be the best variables for establishing an SLI profile in this psycholinguistics areas. Discuss the implications of these findings for the clinical diagnosis and speech-language pathology

Comparing voice-therapy and vocal-hygiene treatments in dysphonia using a limited multidimensional evaluation protocol.

PURPOSE: This study evaluates the effectiveness of two different programs of voice-treatment on a heterogeneous group of dysphonic speakers and the stability of therapeutic progress for longterm follow-up post-treatment period, using a limited multidimensional protocol of evaluation. METHOD: Forty-two participants with voice disorders were randomly assigned to one of two groups. Participants in group 1 received voice-therapy and participants in group 2 received a vocal-hygiene program. Vocal function was assessed before and after treatment. RESULTS: MANOVA analysis Pillai's trace test shows significant pre-post immediate differences between treatments in favor of direct-intervention. Repeated-measures ANOVAs display significant within subjects main effect for follow-up period in the 8 measures considered. Interaction effects of group×time are also found in five out of the eight continuous variables analyzed (3 aerodynamics-acoustic and 2 self-rating), indicating differences between both treatments. Qualitative dimensions (perceptual, laryngoscopic and spectrographic assessments) also support voice-therapy superiority. CONCLUSIONS: Results of this study suggest superiority of a voice-therapy (direct treatment) approach over a vocal-hygiene program (indirect treatment). This advantage is on the majority of the 8 continuous variables analyzed (aerodynamics, acoustic, and self-rating), including qualitative perceptual, laryngoscopic and spectrographic voice-dimensions. The stability of changes is extended during a post-treatment follow-up period. LEARNING OUTCOMES: (1) The reader should distinguish the advantage using one type of treatment or another in clinical contexts. (2) The reader must know the most important direct techniques used in clinical treatment of voice disorders.
