We performed a meta-analysis to determine which surgical method leads to higher treatment satisfaction, lower complication rates, and reduced treatment time, to investigate whether ESIN is the preferred surgical method for treatment of pediatric femoral shaft fractures. Relevant databases were searched for comparative studies of ESIN versus EF for the treating pediatric femoral shaft fractures. Literature reports and quality evaluations were extracted, followed by a systematic review using RevMan 5.3 software. Treatment satisfaction at the last follow-up, primary complications, secondary complications, and relevant time indicators (operation time, hospital stay, clinical healing time, bone healing time) were analyzed. A total of 22 reports were included in this meta-analysis. We found no statistical differences in the tft fractures since it has a reliable curative effect and results in a shorter hospital stay, faster fracture healing, and fewer complications. EF is recommended for fractures with serious injury of the soft tissue to avoid intramedullary infection. Double-blind high-quality randomized studies with larger sample sizes are warranted to confirm our conclusions. IV. IV. Prior work has proposed that major depressive disorder (MDD) is associated with a specific cognitive bias patients with depression seem to learn more from punishment than from reward. This learning bias has been associated with blunting of reward-related neural responses in the striatum. A key question is whether negative learning bias is also present in patients with MDD and comorbid disorders and whether this bias is specific to depression or shared across disorders. We employed a transdiagnostic approach assessing a heterogeneous group of (nonpsychotic)
