Review Meta Analysis
Association of Hemodynamic Factors With Intracranial Aneurysm Formation and Rupture: Systematic Review and Meta-analysis.
Recent evidence suggests a link between the magnitude and distribution of hemodynamic factors and the formation and rupture of intracranial aneurysms. However, there are many conflicting results. ⋯ Pooled analyses of computational fluid dynamics models suggest that an increase in WSS and gradient oscillatory number may contribute to aneurysm formation, whereas low WSS is associated with ruptured aneurysms. The location of the aneurysm at the bifurcation or sidewall may influence the correlation of these hemodynamic factors.

Full-thickness laparoendoscopic excision has been reported for complex endoscopically unresectable colonic polyps. However, the endpoints used in these studies vary significantly and therefore making definitive conclusions regarding the novel procedure would be improved if a common data set were adopted. This study sought to define most appropriate endpoints that should be measured and reported for research on full-thickness laparoendoscopic excision of colonic polyps. ⋯ This study has developed a provisional consensus on a minimum number of feasible and clinically meaningful outcome measures to use in studies of full-thickness laparoendoscopic excision of colonic polyps. Widespread adoption will allow better reporting of the technique and more efficient development in clinical practice.

Comparative Study
Comparison of Outcome Between Surgical and Conservative Management of Symptomatic Spinal Cord Cavernous Malformations.
Intramedullary cavernous malformations (CMs) are rare lesions with unclear natural history. ⋯ Surgical resection of intramedullary CMs eliminates the risk of subsequent hemorrhagic and may achieve satisfactory outcome when patients are carefully selected. Although conservative management is recommended in patients at high surgical risk, they should be closely monitored because of persistent hemorrhagic risk.
