Utility of real-time 3D visualization system in the early stage of phacoemulsification training

●AIM:To determine the teaching effects of a real-time three dimensional(3D)visualization system in the operating room for early-stage phacoemulsification training.●METHODS:A total of 10 ophthalmology residents of the first-year postgraduate were included.All the residents were novices to cataract surgery.Real-time cataract surgical observations were performed using a custom-built 3D visualization system.The training lasted 4wk(32h)in all.A modified International Council of Ophthalmology’s Ophthalmology Surgical Competency Assessment Rubric(ICO-OSCAR)containing 4 specific steps of cataract surgery was applied.The self-assessment(self)and expert-assessment(expert)were performed through the microsurgical attempts in the wet lab for each participant.●RESULTS:Compared with pre-training assessments(self 3.2±0.8,expert 2.5±0.6),the overall mean scores of posttraining(self 5.2±0.4,expert 4.7±0.6)were significantly improved after real-time observation training of 3D visualization system(P<0.05).Scores of 4 surgical items were significantly improved both self and expert assessment after training(P<0.05).●CONCLUSION:The 3D observation training provides novice ophthalmic residents with a better understanding of intraocular microsurgical techniques.It is a useful tool to improve teaching efficiency of surgical education.

Clinical Practice Guideline on Acupuncture and Moxibustion:Adult Major Depressive Disorder(Mild-Moderate Degree):Determination of clinical questions

Determining clinical questions is fundamental to the development of clinical practice guidelines(CPGs),which bridges the initial phases and the final recommendations.It is essential for evidence retrieval and the formulation of recommendations.The scientific rigor and precision in determination of clinical questions directly influence the future implementation and applicability of guidelines.In 2020,the World Federation of Acupuncture-Moxibustion Societies initiated the project of clinical practice guideline on acupuncture and moxibustion for adult major depressive disorder(mild-moderate degree)to address clinical and medical decision-making issues in acupuncture treatment for adult mild to moderate major depressive disorder.This CPG provides systematic recommendations based on clinical evidence,patient values,and other factors,aiding decision-makers,clinicians,and patients in selecting appropriate interventions.This paper discusses and analyzes the determination process of clinical questions,and the related issues during the development of this guideline,aiming to provide a reference for determining clinical questions and developing CPGs in the field of acupuncture and exploring more scientific tools and methods for determining clinical questions in future CPGs.

Small P values may not yield robust findings:an example using REST-meta-PD

Thousands of resting state functional magnetic resonance imaging(RS-f MRI)articles have been published on brain disorders.For precise localization of abnormal brain activity,a voxel-level comparison is needed.Because of the large number of voxels in the brain,multiple comparison correction(MCC)must be performed to reduce false positive rates,and a smaller P value(usually including either liberal or stringent MCC)is widely recommended[1].
