Simulation of a medication and methylation effects on triglycerides in the Genetic Analysis Workshop 20.

ABSTRACT: The GAW20 simulation data set is based upon the companion Genetics of Lipid Lowering Drugs and Diet Network (GOLDN) study fenofibrate clinical trial data set that forms the real data example for GAW20. The simulated data problem consists of 200 simulated replications of what might happen if we were to repeat the GOLDN clinical trial 200 independent times, for these exact same subjects, but using a new fictitious drug (called "genomethate") that has a pharmaco-epigenetic effect on triglyceride response. For each replication, the pre-genomethate values at visits 1 and 2 are constant (ie, pedigree structures, age, sex, all phenotypes, covariates, genome-wide association study (GWAS) genotypes, and visit 2 methylation values), the same as the real GOLDN data across all 200 replications. Only the post-genomethate treatment data (ie, methylation and triglyceride levels for visits 3 and 4) change across the 200 replications. We postulate a growth curve pharmaco-epigenetic response model, in which each patient's response to genomethate treatment is individualized, and is dependent upon their genotype as well as the methylation state for key genes.

Project description:Background:Simulation-based education (SBE) is increasingly endorsed as an educational strategy. It allows health-care professionals to practice clinical skills within a safe learning environment, and requires devices for simulation or simulated patients, trained teachers, and an appropriate environment. The objective of this study was to evaluate perceptions of participants on SBE and an SBE workshop. Methods:A 1-day SBE workshop was conducted on September 4, 2018, in collaboration with Laerdal Global Health Nepal and the National Centre for Health Professions Education (NCHPE), Institute of Medicine, Kathmandu, Nepal. Semistructured pretest and posttest questionnaires were used to evaluate the perceptions of participants regarding SBE and the effectiveness of the workshop. Data were analyzed using SPSS 21. Results:The mean difference in participant perceptions of SBE before and after participation in the workshop was significant (P<0.05) on seven statements: enhances communication skills (pretest 4.53±0.72, posttest 4.84±0.75; P=0.03), helps in seeing and managing even rarest of cases (pretest 3.59±1.00, posttest 4.21±0.92; P=0.02), overcomes the problem of uncooperative patients (pretest 3.12±0.93, posttest 3.95±1.22; P=0.004), increases confidence of students in dealing with real patients (pretest 4.29±0.77, posttest 4.79±0.42; P=0.041), enables preparation of rating scales for skills and attitude evaluation (pretest 3.76±0.83, posttest 4.11±0.76; P=0.049), provides immediate feedback during simulation (pretest 4.06±0.9, posttest 4.58±0.51; P=0.016), and keeps materials/equipment ready before simulation (pretest 4.29±0.68, posttest 4.79±0.53; P=0.007). Mean scores for participant feedback on the workshop using a Likert scale of 1-5 (5= strongly agree, 1= strongly disagree) were notable: objective of workshop fulfilled (4.16±0.688), session very interesting (4.37±0.597), session useful for future job (4.47±0.513), scenario relevant to subject (4.21±0.787), what I learnt will be useful in practice (4.05±0.78), resource persons/facilitators were helpful and effective (4.37±0.597), professional (4.42±0.507), and answered all questions (4.32±0.478), and course content was presented clearly (4.26±0.452). Almost all participants found the workshop useful and well presented, and suggested conducting such workshops frequently. Conclusion:The SBE workshop produced substantial differences in perceptions of participants. Participants found the workshop effective in improving knowledge and understanding of SBE.
