Information and communication technology, mobile devices, and medical education

IntroductionInformation and communication technologies (ICT) are practical and highly available tools. In medical education, ICTs allow physicians to update their knowledge and remember the necessary information within reach of current mobile devices. ICTs as preparation tools for medical education have not been reported for medical students in Mexico. MethodologyTo assess the use of mobile devices as ICTs with medical education purposes, we distributed a questionnaire through an online survey management system to all the medical students (n=180) from a private university in Mexico City, 100% agreed to participate. We developed a questionnaire based on previous surveys and adapted it to our university. ResultsAll participants reported possession of an electronic mobile device, and 95% used it regularly for learning purposes. Regardless of the school year, the most frequent usage given to these devices was the search and reading of medical articles, the use of medical calculators, and taking notes. As the levels in career advances, there was a reduction in the use of electronic devices. According to the students, the main barriers towards using mobile devices for learning purposes were both the lack of access to the Internet and permission from the professor to use them. ConclusionMost medical students use mobile devices for learning purposes, but usage changes during their education. It is convenient to encourage the use of mobile devices and the development of ICT skills as tools for educational purposes rather than banning their use in schools and hospitals.

Association between the brain-derived neurotrophic factor Val66Met polymorphism and overweight/obesity in Mexican pediatric population

BackgroundThe functional brain-derived neurotrophic factor (BDNF) rs6265 (G196A; Val66Met) single nucleotide polymorphism has been associated with eating disorders, BMI and obesity in distinct populations, both adult and pediatric, with contradictory results involving either Val or Met as the risk variant.\n\nAim of the studyTo determine the association between the BDNF Val66Met polymorphism and BMI in Mexican children and adolescents.\n\nMethodsBDNF Val66Met genotyping by restriction fragment length polymorphism and nutritional status characterized by their BMI-for-age z-scores (BAZ) from pediatric volunteers recruited in Mexico City (n=498) were analyzed by Fishers exact test association analysis. Standardized residuals (R) were used to determine which genotype/allele had the major influence on the significant Fishers exact test statistic. Odds ratios were analyzed to measure the magnitude and direction of the association between genotype and normal weight ([&ge;] -2 SD < +1 SD) and overweight ([&ge;] +1 SD, including obesity, Ow+Ob) status with 95% confidence intervals to estimate the precision of the effect as well as 95% credible intervals to obtain the most probable estimate.\n\nResultsComparisons between GG (Val/Val), GA (Val/Met) and AA (Met/Met) genotypes or Met homozygotes vs. Val carriers (combination of GG and GA genotypes) showed significant differences (p=0.034 and p=0.037, respectively) between normal weight and the combined overweight and obese pediatric subjects. Our data showed that children/adolescents homozygous for the A allele have increased risk of overweight compared to the Val carriers (Bayes OR= 4.2, 95% CI**[1.09-33.1]).\n\nConclusionThis is the first study showing the significant association between the BDNF rs6265 AA (Met/Met) genotype and overweight/obesity in Mexican pediatric population.\n\nO_LIMexico has one of the highest pediatric overweight and obesity prevalence\nC_LIO_LIBDNF has been associated with body weight regulation.\nC_LIO_LIThe BDNF rs6265 SNP (G196A; Val66Met) has been associated with eating disorders, BMI and obesity, with contradictory results in both adults and children.\nC_LIO_LIWe found significant associations between BDNF Val66Met AA (Met/) genotype and overweight/obesity in Mexican pediatric population\nC_LIO_LIMet homozygote children/adolescents increased four times the risk of being classified in the overweight group (Ow+Ob) relative to Val carriers\nC_LI
