Purpose: This research paper aims to explore the influence of social media–based knowledge-sharing intentions (SMKI) on prospective authentic leadership development (ALD) to deal with the future crisis. In the existing literature, to the best of the authors' knowledge, there is no significant empirical evidence to test the relationship between SMKI and ALD. Thus, this study contributes to the growing literature regarding the role of SMKIs, ALD, social media–based knowledge-sharing behavior (SMKB) and facilitating conditions (FCs). However, in this study, the authors developed a conceptual framework based on technology adoption and leadership theory. It was used to identify preservice educational leaders' SMKIs and their effect on ALD to deal with an educational crisis during the COVID-19 pandemic. Furthermore, SMKIs are strengthening ALD, directly and indirectly, using SMKB and FCs. Design/methodology/approach: In this study, the higher education students are considered preservice leaders who were enrolled in educational leadership and management programs. However, this study's target population and sample are students enrolled in educational leadership and management programs. Therefore, higher education students are considered preservice educational leaders. Therefore, a multilevel questionnaire survey approach was adopted to collect data from preservice educational leaders (n = 451 at Time 1 and n = 398 at Time 2) enrolled in education departments in the selected universities in Pakistan. A total of 398 survey questionnaires were finalized with a return ratio of 89%. The partial least square structural equation modeling with SmartPLS 3.2.8 was used for the data analysis. Findings: This research found that SMKIs are positively and significantly connected with ALD. This study also confirms that SMKB significantly and positively mediates the relationship between SMKIs and ALD. Therefore, this study concludes that preservice educational leaders were ready to adopt SMKB. Practical implications: Social media–based knowledge sharing can be helpful to develop authentic leadership among preservice educational leaders during a crisis. Preservice educational leaders as authentic leaders can prove to be an asset in dealing with the COVID-19 pandemic crisis. Originality/value: This research integrated the technology adoption model and leadership theory to provide empirical evidence of SMKIs' direct and indirect influence on ALD through social media–based knowledge-sharing actual use behavior by preservice educational leaders during the COVID-19 pandemic. Moreover, the moderated mediating effect of the FCs was also studied in the relationship between SMKIs and actual user behavior as well as ALD. © 2022, Emerald Publishing Limited.

Background: Gemtuzumab ozogamicin (GO), an anti-CD33 immunoconjugate Antibody is currently approved in combination with 7 + 3 in low- and intermediate risk acute myeloid leukaemia (AML). These patients are candidate for consolidation with autologous stem cell transplantation (ASCT) particularly when MRD- is obtained. GO can improve the rate of MRD negativity. There are limited data on the effect of its addition on the mobilization of Hemopoietic Stem Cells (HSC). Aims: To assess the feasibility of mobilization of HSC after re-introduction into market of GO at 3mg/m2 in 2019. Methods: We retrospectively studied AML patients undergoing 3+7 + GO induction and Ara-C + Daunorubicine + GO, consolidation (doses are derived from label instructions and ALFA0701 study) and mobilization on day +20 using GCSF 10μg/kg. CD34+ were monitored, and patients were harvested when a threshold of 20 cells/μL was reached in peripheral blood. Results: In 2020 and 2021, also considering constrains caused by COVID-19 pandemics, we attempted mobilization in our 3 Italian centres of 14 patients with a diagnosis of CD33+ de novo-AML. The median age was 52 years (range 29-65 yrs.), 4 were males and 10 females;11 patients carried a mutation of NPM1 and all had a normal karyotype except one with t(10p12;11q14) (Table 1). All received 3+7+GO induction and achieved a CR. Therefore, we started consolidation (total ARA-C 8g/m2) + GO as inpatient. Ten patients (71%) reached the established threshold of 20 CD34+ /μL and were successfully harvested, while 4 patients (29%) failed mobilization. The median day of apheresis was D+26 from the start to chemotherapy (range 22- 39). The median number of circulating CD34+ cells on the day of collection was 35.9 cells/μL (range 20-2153 cells/μL). The median CD34+ harvested was 4.65 x 106/kg (range 1.8- 44.6 x 106/kg). In our cohort, 4 patients (28% of the entire cohort and 40% of the harvested patients) underwent ASCT, 3 achieved favourable engraftment, while in the last patient ASCT is ongoing. Several reasons prevented ASCT in the remaining 6 patients: 3 patients underwent allogeneic SCT (2 had positive MRD on harvested apheresis;1 was reclassified as high-risk ELN2017 due to RUNX1 mutation resulting from NGS panel), 2 refused ASCT and one suffered early relapse. Summary/Conclusion: In our patients, the addition of GO did not impair HSC mobilization and harvesting that was reached in about 71% of cases, similarly to the AML-10 trial of the EORTC and GIMEMA Leukemia Groups where 70% of patients were successfully harvested. Our data are particularly interesting because in the pivotal ALFA0701 study, only one patient underwent Autologous- SCT, but in the control arm. An important limit of our case-series is that only 4 patients were auto-transplanted, so we have scant data on engraftment. In particular, evaluating day to engraftment of platelets would be interesting, given the known increase of thrombocytopaenia in patients treated with GO. In conclusion, mobilization with GO is feasible and further studies are warranted to evaluate the effects of fractioned doses of GO on HSC mobilization and ASCT outcome;the ongoing trial GIMEMA AML1819 - EudraCT number 2019-003871-20 - will prospectively assess the effect of GO, but with lower doses of ARA-C (total ARA-C 6 g/m2).
