ABSTRACT
Objective:To analyze the relationship between the developmental eye movement (DEM) test results and the vocabulary size in Chinese children with developmental dyslexia.Methods:A cross-sectional study was conducted.A total of 1 243 fifth grade students from 10 primary schools were enrolled from September to December 2019 in Tianjin, among which there were 664 males and 579 females, with the average age of (10.68+ 0.53) years old.The Chinese vocabulary test and intelligence test were carried out.Eighty-five dyslexic children with subaverage vocabulary size were selected as the experimental group and 54 normal children were selected as the control group.The DEM test was conducted in the two groups, and the vertical time, the horizontal adjustment time, the ratio of horizontal to vertical time and the total number of errors were recorded and analyzed.The differences in positive rate of dyslexia, various DEM test indicators between different genders and different groups were analyzed.The correlations between vocabulary size and vertical time, horizontal adjustment time, the ratio of horizontal to vertical time and the total number of errors were analyzed.This study protocol adhered to the Declaration of Helsinki and was approved by an Ethics Committee of School of Optometry, Tianjin Vocational Institute (No.ysgxyll001). Written informed consent was obtained from the guardian of each subject.Results:The total positive rate of dyslexia was 6.83%(85/1 243), and the positive rate of 9.33%(62/664) in boys was higher than 3.97%(23/579) in girls, with a significant difference between them( χ2=13.974, P<0.001). There were no statistically significant differences in age, vocabulary size, vertical time, horizontal adjustment time, and the ratio of horizontal to vertical time between different genders in the control group (all at P>0.05). The vocabulary size of girls in the experimental group was larger than that of boys, showing a statistically significant difference ( t=-2.259, P=0.027). There was no significant difference in age, vertical time, horizontal adjustment time, and the ratio of horizontal to vertical time (all at P>0.05). The vertical time and horizontal adjustment time of the experimental group were longer than those of the control group, and the differences were statistically significant ( t=-4.848, -4.297; both at P<0.001). There was no statistically significant difference in the ratio of horizontal to vertical time between the two groups ( t=0.126, P=0.900). The total number of errors was 0(0, 1) in the experimental group, which was higher than the control group 0(0, 0), with a significant difference between them ( H=1.979, P=0.001). The vocabulary size of students in the two groups was negatively correlated with the vertical time, horizontal adjustment time and the total number of errors ( r=-0.397, P<0.001; r=-0.355, P<0.001; r s=-0.180, P=0.034), and was not obviously correlated with the ratio of horizontal to vertical time ( r=0.038, P=0.656). Conclusions:The DEM test scores of Chinese children with developmental dyslexia are higher than those of normal children, and there is no difference between different genders.The lower the scores of vocabulary size test, the higher the scores of DEM test.
ABSTRACT
BACKGROUND AND PURPOSE: Benign epilepsy with centrotemporal spikes (BECTS) is one of the most common pediatric epilepsies, and it generally has a good prognosis. However, recent research has indicated that the epileptic activity of BECTS can cause cognitive defects such as language, visuospatial, and auditory verbal memory deficits. This study assessed language-delivery deficits in BECTS patients using diffusion-tensor magnetic resonance imaging (DTI). METHODS: T1-weighted MRI, DTI, and language tests were conducted in 16 BECTS patients and 16 age-matched controls. DTI data were analyzed using the TRActs Constrained by Underlying Anatomy tool in FreeSurfer 5.3, and 18 major white-matter tracts were extracted, which included 4 language-related tracts: the inferior longitudinal fasciculus, superior longitudinal fasciculus-parietal terminations, superior longitudinal fasciculus-temporal terminations, and uncinate fasciculus (UNC). Language tests included the Korean version of the Receptive and Expressive Vocabulary Test, Test of Problem-Solving Abilities (TOPS), and the mean length of utterance in words. RESULTS: The BECTS group exhibited decreased mean fractional anisotropy and increased mean radial diffusivity, with significant differences in both the superior longitudinal fasciculus and the left UNC (p<0.05), which are the language-related white-matter tracts in the dual-loop model. The TOPS language test scores were significantly lower in the BECTS group than in the control group (p<0.05). CONCLUSIONS: It appears that BECTS patients can exhibit language deficits. Seizure activities of BECTS could alter DTI scalar values in the language-related white-matter tracts.

Abstract Introduction: The government intends to position Colombia as a health and welfare tourism destination. To achieve this goal, it is necessary to increase the levels of English proficiency in health professionals, which is in line with the goal set by the Colombian Ministry of National Education for 2014: 20% of medical graduates should score at intermediate or advanced English proficiency levels. Objectives: To determine if the bilingualism goal set for 2014 was achieved by students of undergraduate medical programs in Colombia. Materials and methods: Descriptive and statistical approach (parametric and nonparametric tests) based on data from the Saber Pro test (2011-2015) for medical programs offered in universities of academic nature. Results: The overall percentage of students who met the goal countrywide (28.6%) was satisfactory; however, only 16 medical programs out of 43 (37.2%) achieved the goal. Conclusions: In general, the English proficiency level of potential medical graduates is aligned with the government's goal. However, there is much to be improved considering that about 70% of future medical graduates do not have an intermediate or advanced level in this skill.
Resumen Introducción. El gobierno propuso posicionar a Colombia como un destino turístico de salud y bienestar, siendo uno de los objetivos aumentar los niveles de competencia del inglés en los profesionales de la salud. Esto se relaciona con la meta, para 2014, del Ministerio de Educación Nacional (MEN) de que 20% de los graduados deberían clasificar en nivel intermedio o superior en inglés. Objetivos. Analizar el cumplimiento de la meta establecida por el MEN para los graduandos de los programas de medicina. Materiales y métodos. Aproximación descriptiva y estadística (pruebas de proporciones paramétricas y no paramétricas) que empleó datos de la prueba Saber Pro (2011-2015) para los programas de medicina de las instituciones de educación superior de carácter académico universitario. Resultados. El porcentaje global de estudiantes que cumplió la meta (28.6%) fue satisfactorio; sin embargo, solo 18 de 43 (37.2%) programas de medicina la cumplieron. Conclusiones. El nivel de inglés de los potenciales graduados de los programas de medicina está alineado con la meta del gobierno. No obstante, hay mucho por mejorar si se tiene en cuenta que cerca del 70% de los futuros graduados de los programas de medicina no alcanza un nivel intermedio o superior en esta competencia.
