Inclusion of MCQs written by radiology residents in their annual evaluation: innovative method to enhance resident ’s empowerment?
AbstractAimWe hypothesized that multiple-choice questions written by radiology residents(MCQresident) for their weekly case presentations during radiology staff meetings could be used along with multiple-choice questions written by radiology teachers(MCQteacher) for their annual evaluation. The current prospective study aimed at determining the educational characteristics of MCQresident and at comparing them with those of MCQteacher.MethodsFifty-one radiology residents of the first to the fifth year of training took the 2017 exam that contained 58 MCQresident and 63 of MCQteacher. The difficulty index, the discrimination power, and the distractor ’s quality were calculated in the two series of MCQs and were compared by using Studentt test. Two radiologists classified each MCQ according to Bloom ’s taxonomy and frequencies of required skills of both MCQ series were compared.ResultsThe mean ± SD difficulty index of MCQresident was statistically significantly higher than that of MCQteacher (0.81 ± 0.1 vs 0.64 ± 0.2;p

Given the high prevalence of screen viewing among children worldwide, its impact on children's health has become a cause for concern. Unfortunately, little information on the independent association between sleep habits and screen time in French children is currently available. The main aim of this study was to assess possible...

Conclusions: EVs from buffaloes infected with Theileria spp. were successfully isolated and characterized. This is an advance in the knowledge of host-parasite relationship that contributes to the understanding of host immune response and theileriosis evasion mechanisms. These findings may pave the way for searching new EVs candidate-markers for a better production of safe biological products derived from buffaloes.
Conclusions: JZTX-X selectively suppresses Kv4.2 and Kv4.3 potassium channe l activity in a concentration- and voltage-dependent manner and causes long-lasting mechanical hyperalgesia.
Conclusion: Our results suggest a different biochemical composition of S. polymorpha venom, based on the different effects of four venom fractions on the cells tested, according to statistical evidence. Fractions F6 and F7 caused the most important alterations.
