Objectives: Child life interventions reduce the anxiety of medical procedures but are not always available in emergency departments. In this study, we determined the effect of parent-directed tablet computer use without child life direction on patient anxiety and on parent and suturing clinician experience during pediatric facial laceration repair., Methods: In a children's hospital emergency department, we enrolled children 2 to 12 years of age undergoing unsedated facial laceration repairs and randomized them to parent-directed tablet computer distraction or standard supportive care. We measured anxiety using the Observational Scale of Behavioral Distress-Revised (OSBD-R) for 5 procedure phases from videotaped laceration repairs. We compared OSBD-R scores for 5 phases and weighted averages between the tablet and standard care groups. Parents and suturing clinicians completed surveys about their experiences after the procedures., Results: From April 2014 to July 2015, 77 patients (39 tablet, 38 standard) underwent repairs. Age, use of restraint, procedure duration, and number of sutures were similar between the 2 groups. The groups did not differ in procedure phase or weighted-average OSBD-R scores. Parents in the tablet group reported less personal anxiety compared with parents in the standard group (P = 0.01). In a post hoc subgroup analysis, subjects in the unrestrained tablet group had lower OSBD-R scores during the anesthetic injection phase than did subjects in the unrestrained standard group (P = 0.04). If restrained, subjects in the tablet group had higher OSBD-R scores during the anesthetic injection phase than did subjects in the standard group (P = 0.048)., Conclusions: Unrestrained children may benefit from parent-directed tablet computer distraction. Parents who operate the device are less anxious during their children's procedures., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2018 Wolters Kluwer Health, Inc.

Antibodies are promising post-exposure therapies against emerging viruses, but which antibody features and in vitro assays best forecast protection are unclear. Our international consortium systematically evaluated antibodies against Ebola virus (EBOV) using multidisciplinary assays. For each antibody, we evaluated epitopes recognized on the viral surface glycoprotein (GP) and secreted glycoprotein (sGP), readouts of multiple neutralization assays, fraction of virions left un-neutralized, glycan structures, phagocytic and natural killer cell functions elicited, and in vivo protection in a mouse challenge model. Neutralization and induction of multiple immune effector functions (IEFs) correlated most strongly with protection. Neutralization predominantly occurred via epitopes maintained on endosomally cleaved GP, whereas maximal IEF mapped to epitopes farthest from the viral membrane. Unexpectedly, sGP cross-reactivity did not significantly influence in vivo protection. This comprehensive dataset provides a rubric to evaluate novel antibodies and vaccine responses and a roadmap for therapeutic development for EBOV and related viruses., (Copyright © 2018 Elsevier Inc.
