Telemedicina como herramienta de enseñanza de la endocrinología en estudiantes de medicina / Telemedicine as a teaching tool for endocrinology in medical students

INTRODUCCIÓN: El estudiante de medicina actualmente está inmerso en una sociedad altamente tecnologizada, dónde la telemedicina podría ser utilizada como un instrumento hacia un mayor aprendizaje. OBJETIVO: El objetivo del estudio es analizar el logro de competencias y el grado de satisfacción de los estudiantes medicina con la utilización de la telemedicina como estrategia didáctica en la enseñanza de la endocrinología. MATERIAL Y MÉTODO: Estudio preexperimental, correlacional, transversal y con medición posterior a la intervención. La muestra estuvo constituida por los 40 estudiantes de tercer año de medicina (24 hombres y 16 mujeres) que realizaron su práctica de endocrinología durante el segundo semestre del 2017. Se les evaluó los logros alcanzados en las competencias a través de una escala de apreciación y se midió el grado de satisfacción con la actividad docente a través de un cuestionario validado (α de Cronbach de 0,9565). RESULTADOS: El rendimiento de los estudiantes en el módulo de teleendocrinología al evaluar las competencias de analizar, sintetizar y presentar un caso clínico teleconsultado fue de 6,1 en una escala de 1 a 7, y no se encontraron diferencias según sexo. El 90% de los estudiantes consideró muy motivadora la metodología de enseñanza basada en la telemedicina y el 82,5% consideró que esta metodología favorece la integración de los contenidos. CONCLUSIONES: La telemedicina puede ser utilizada como una herramienta para evaluar competencias académicas de endocrinología en los estudiantes de pregrado de medicina, y que estos muestran un alto grado de satisfacción con este tipo de actividad docente.

INTRODUCTION: The medical student is currently immersed in a highly technological society, where telemedicine could be used as an instrument towards greater learning. OBJECTIVE: The objective of the study is to analyze the achievement of competences and the degree of satisfaction of medical students with the use of telemedicine as a didactic strategy in the teaching of endocrinology. MATERIAL AND METHOD: Pre-experimental, correlational, cross-sectional study and measurement after the intervention. The sample consisted of 40 third-year medical students (24 men and 16 women) who performed their endocrinology practice during the second semester of 2017. They were evaluated the achievements in the competences through a scale of appreciation and The degree of satisfaction with the teaching activity was measured through a validated questionnaire (Cronbach's de 0.9565). RESULTS: The performance of the students in the teleendocrinology module when evaluating the competences of analyzing, synthesizing and presenting a teleconsultated clinical case was 6.1 on a scale of 1 to 7, and no differences were found according to sex. 90% of the students considered the teaching methodology based on telemedicine very motivating and 82.5% considered that this methodology favors the integration of the contents. CONCLUSIONS: Telemedicine can be used as a tool to evaluate endocrinology academic competences in undergraduate medical students, and that they show a high degree of satisfaction with this type of teaching activity.

Sensory strategies of postural sway during quiet stance in patients with haemophilic arthropathy.

INTRODUCTION: The sensory strategies of postural control in adult haemophilic arthropathy patients are still poorly understood. AIM: To determine sensorial posture-control strategies through postural sway frequency analysis when in a bipedal quiet stance with and without visual stimulus deprivation in healthy subjects and patients with haemophilic arthropathy. Secondarily, to determine the irregularity of postural balance control through sample entropy (SampEn). METHODS: A triaxial accelerometer attached at the L3 level determined the displacement and acceleration of the centre of mass (DCoM and ACoM, respectively) under open- and closed-eyes conditions. Sensorial strategies were studied by spectral analysis of the DCoM signal, divided into low, medium and high frequencies for visual/vestibular, cerebellum and somatosensory strategies respectively. DCoM irregularity was also analysed by SampEn. RESULTS: Fifteen young, healthy subjects and fifteen young, haemophilia patients were included. The mediolateal DCoM and anteroposterior ACoM differed between groups. During the open-eyes condition, haemophiliacs presented limited high and medium frequencies, and more low frequency bands as compared to non-haemophiliacs (P<.05). In the closed-eyes condition, haemophiliacs had a minor percentage of high frequencies but an elevated percentage of low frequencies as compared to non-haemophiliacs (P<.05). Non-haemophiliacs had higher SampEn than haemophiliacs in the mediolateral axis with open- and closed-eyes (P<.05 and <.001, respectively). CONCLUSIONS: The presented results indicate that patients with haemophilic arthropathy, as compared to healthy subjects, have less postural control irregularity and poor somatosensory system contributions that are compensated by more vestibular inputs.

Association of CAPN1 316, CAPN1 4751 and TG5 markers with bovine meat quality traits in Mexico.

We examined allele and genotype frequencies for the molecular markers CAPN1 316, CAPN1 4751 and TG5, and determined whether they are associated with beef quality traits in Mexican cattle. One hundred and twenty-four longissimus dorsi muscle samples were collected from cattle from north, central and southern Mexico. CAPN1 316 and CAPN1 4751 frequencies were determined using the allelic discrimination assay and the TG5 marker was typed by PCR-RFLP. Meat quality traits included intramuscular fat content (IMF) and tenderness determined by Warner-Bratzler shear force (WBSF) at 24 h postmortem. The association test was made using a mixed model, including genotypes, genetic group, and sampling location as fixed effects. Least squares means and significant interactions were compared using least significant differences based on the mixed procedure. CAPN1 316 CC was found at a low frequency (0.03) and has been reported as a favorable genotype associated with tenderness meat. Genotype frequencies for CAPN1 4751 were similar in favorable (CC) and unfavorable (TT) genotypes (0.26 and 0.28, respectively). The TG5 CC genotype had a frequency of 0.73, while the TT genotype frequency was 0.01. The means for WBSF and IMF were 4.08 ± 1.35 kg and 5.23 ± 2.14%, respectively. Sampling site and the CAPN1 316 genotypes significantly affected WBSF (P < 0.05). Samples collected from Hermosillo, Sonora, had the lowest WBSF (P < 0.05), while those collected in Veracruz were toughest (WBSF = 5.267 kg). The effect of GG and TG5 genotypes on IMF was significant (P < 0.05). CAPN1 316 and TG5 markers were found to be significantly associated with beef quality traits and thus will be useful for Mexican beef characterization.
