The purpose of this article is to clearly describe goal-directed elopement (also called “bolting,” “fleeing,” or “running away”) and the unique challenge it presents for teachers in classroom settings. If only she understood why Don eloped, maybe she could develop a plan that would decrease this dangerous behavior. Montrose was determined to get a handle on Don’s elopement she did not want to risk losing all the progress they had made in the classroom. She brought this concern to the school administration, and they warned that if she could not predict or control his running off, they would have no choice but to recommend a more restrictive placement. Montrose’s immediate distress, she remained extremely concerned about her ability to safely supervise him during his school day. He had scaled the playground fence, crossed a busy street, and was walking into a nearby convenience store. When she reached the far end of the playground, she spotted Don. Montrose sent her two classroom aides to check those locations while she quickly ran the perimeter of the fenced-in playground area. In these situations, he could typically be found rifling through the candy jar in the main office, taking snacks from the cafeteria snack bar, or helping himself to a treat from the treasure box in Mr. Don had run away from supervised areas before however, he only ever ran away from the classroom or the group when walking through the hallway. Montrose as she realized her student Don was gone she could not find him anywhere on the playground. Conclusion: The treatment effect of lenadogene nolparvovec on BCVA and vision-related quality of life observed 96 weeks (2 years) after treatment in RESCUE and REVERSE was sustained at 3 years in RESTORE, with a maximum follow-up of 52 months (4.3 years) after the onset of vision loss.A wave of panic washed over Ms. The mean VFQ-25 composite score increased by 7 points compared with baseline. The final mean BCVA was 1.26 logarithm of the minimal angle of resolution 48 months after the onset of vision loss. There was a progressive and sustained improvement of BCVA up to 52 months after the onset of vision loss. Results: The population of MT-ND4 subjects enrolled in RESTORE was representative of the combined cohorts of RESCUE and REVERSE for mean age (35.1 years) and gender distribution (79% males). Vision-related quality of life was reported using the visual function questionnaire-25 (VFQ-25). A locally estimated scatterplot smoothing regression model was used to analyze changes in BCVA over time. The best-corrected visual acuity (BCVA) was assessed over a period of up to 52 months after onset of vision loss. After 96 weeks, 61 subjects were enrolled in the long-term follow-up study RESTORE. Methods: In RESCUE and REVERSE, 76 subjects with LHON because of the m.11778 G.A mutation in the mitochondrial gene ND4 received a single unilateral intravitreal injection of lenadogene nolparvovec. RESTORE is the long-term follow-up study of subjects treated in the RESCUE and REVERSE trials. Abstract : Background: RESCUE and REVERSE were 2 Phase 3 clinical trials that assessed the efficacy and safety of intravitreal gene therapy with lenadogene nolparvovec (rAAV2/2-ND4) for the treatment of Leber hereditary optic neuropathy (LHON).
