Endovascular surgical procedures require visual-spatial coordination in workspaces with restricted motions and temporally limited imaging. The development of the skills needed for these procedures can be facilitated by 3D simulator-based training. Cerebral angiography (CA) has lagged behind in this training approach due to the lack of validated, realistic training models, relying strictly on clinical case exposure frequency ("number of hours logged") as a means of assessing proficiency. ⋯ No change in aneurysm coiling quality was found, with a slight decrease in number of parent artery coil protrusions. High MRT individuals were better able to establish necessary tools prior to coiling, however, no other MRT-specific changes were seen. This work identifies the utility of simulation-based CA training in identifying the particular difficulties trainees experience in learning procedural skills, including prevention of perforations, proper positioning and success of coils within the aneurysm.

Anal fistula is a common perianal disease, but primary complex anal fistulas with 7 external openings is extremely rare. ⋯ In the treatment of complex anal fistula, the combined application of 3D MRI model will be beneficial to obtain better surgical results.

For the reconstruction of severe upper extremity trauma involving arterial injury in civilian patients, it is generally recommended that the revascularization time be shortened using a temporary intravascular shunt (TIVS). However, if a flow-through type vastus lateralis muscle (VLm) flap can be harvested in 20 minutes and bypassed at the obstructed ischemic zone within 30 minutes, blood flow can be restored as quickly or more quickly than when using a TIVS, eliminating the need for a TIVS. This procedure was applied in the reconstruction of 3 cases of severe extremity trauma with vascular injury. ⋯ The flow-through-type VLm flap can be applicable as a bypass graft for a 20 cm defect at any region distal to the elbow. In addition, harvesting the flap attached to blood-rich muscle not only controls the infection of contaminated wounds through the filling of dead space, but also has the potential to replace damaged muscle or tendon tissue. Even though TIVS placement is currently used extensively in this field of treatment, its role could be significantly reduced if a flow-through-type VLm flap can be harvested within 20 minutes.

The new coronavirus disease 2019 (COVID-19) pandemic is raging worldwide. The administered vaccination has become a significant vehicle against the virus. Three hypotheses were made and required for validation: the number of vaccines administered is related to the country gross domestic product (GDP), vaccines can reduce the fatality rate (FR), and dashboards can present more meaningful information than traditionally static visualizations. Research data were downloaded from the GitHub website. The aims of this study are to verify that the number of vaccination uptakes is related to the country GDP, that vaccines can reduce FR, and that dashboards can provide more meaningful information than traditionally static visualizations. ⋯ This research uses the Kano map, forest plot, and choropleth map to verify the 3 hypotheses and provides insights into the vaccination effect against the FR for relevant epidemic studies in the future.

Biliary atresia (BA) is a devastating progressive fibro inflammatory disorder in infants. The exact etiology of BA is still unclear. This study aimed screen key genes potentially associated with the occurrence of BA. ⋯ In conclusion, COL3A1, CXCL8, VCAN, THBS2, and COL1A2 are potentially crucial genes in BA. The logistic regression model constructed based on them could predict the BA sample relatively reliably.
