Aims The purpose of this study was to explore the relationship of social networking sites (SNSs) addiction on nurses’ performance and how this relationship was mediated by task distraction and moderated by self‐management. Design This cross‐sectional study is designed to empirically test the relationship of SNSs addiction, task distraction, and self‐management with the nurses’ performance. Methods Data were collected by conducting an online survey on nurses across the world using a web‐based questionnaire developed through ‘Google Docs’ and distributed through Facebook from 13 August 2018 – 17 November 2018. The Facebook groups were searched using the selected key terms. In total, 45 groups were found to have relevance to this research; therefore, request was made to the admins of these groups to participate in this research and to post a link in their groups. Only 19 group admins responded positively by uploading a link of the research instrument on their respective group pages and 461 members of these groups participated in the research. Results Results of the data collected from 53 different countries indicated that SNSs addiction results in lowering the nurses’ performance. This relationship is further strengthened by task distraction introduced as a mediating variable. The results show that self‐management mediates the relationship between SNSs addiction and employees’ performance. Moreover, the results of the study confirm that self‐management reduces the negative impact of SNSs addiction on nurses’ performance. Conclusion Social networking sites (SNSs) addiction and task distraction reduce the nurses’ performance, whereas self‐management enhances nurses’ performance. Impact This study addresses the problem of using SNSs at the workplace and its potential effect on nurses’ performance. Results demonstrate that SNSs addiction reduces the performance which is further decreased by task distraction; however, self‐management of nurses can enhance the nurses’ performance. The research has numerous theoretical and practical implications for hospital administration, doctors, and nurses.

Purpose: To assess the feasibility of extraction of a chronically implanted subretinal electrode array. Methods: Inactive, polyimide strips (10 mm × 1.5 mm × 15 μm) were surgically implanted into the subretinal space of 8 rabbits using a mostly ab externo approach. Pre- and postoperative clinical examinations, electroretinography and in some cases optical coherence tomography were performed to follow the course of the eyes. Two months after implantation, the polyimide strips were extracted from 5 eyes; 2 animals kept the implants and served as controls. All animals were then sacrificed and eyes enucleated for histological examination. Results: All 8 surgeries yielded successful placement of the arrays into the subretinal space. All 5 extraction surgeries were performed without obvious complications. Clinical examinations and electroretinography did not reveal any significant abnormalities. The histological examinations showed alterations from normal anatomy in all animals; the anatomical changes in the explanted animals were relatively mild and confined to the area of the surgery. Conclusions: Successful extraction of electrode arrays from the subretinal space of rabbits can be reliably performed 2 months after implantation, which is beyond the time period when postoperative scarring would be most intense.
