Stem Cells Collection and Mobilization in Adult Autologous/Allogeneic Transplantation: Critical Points and Future Challenges.

Achieving successful hematopoietic stem cell transplantation (HSCT) relies on two fundamental pillars: effective mobilization and efficient collection through apheresis to attain the optimal graft dose. These cornerstones pave the way for enhanced patient outcomes. The primary challenges encountered by the clinical unit and collection facility within a transplant program encompass augmenting mobilization efficiency to optimize the harvest of target cell populations, implementing robust monitoring and predictive strategies for mobilization, streamlining the apheresis procedure to minimize collection duration while ensuring adequate yield, prioritizing patient comfort by reducing the overall collection time, guaranteeing the quality and purity of stem cell products to optimize graft function and transplant success, and facilitating seamless coordination between diverse entities involved in the HSCT process. In this review, we aim to address key questions and provide insights into the critical aspects of mobilizing and collecting hematopoietic stem cells for transplantation purposes.

A Comparative Study of Data Collection Methods in the Process of Nursing: Detection of Chemotherapy Side Effects Using a Self-Reporting Questionnaire.

Ocular vestibular evoked myogenic potentials (oVEMP) and cervical VEMP (cVEMP) are newer diagnostic methods, which allow an insight into the otolith senses. Our aim was to determine changes in certain parameters of the VEMP wave complex after successfully performed repositioning procedure, as an indicator of the state of recovery in patients with benign paroxysmal positional vertigo (BPPV). This may confirm the theory of otolith returning into the area of otolithic senses. The study included 48 patients with unilateral posterior semicircular canal BPPV. On their first arrival, otoneurological examinations, oVEMP and cVEMP tests were performed. The same were included in follow up check-ups scheduled at seven days and six months after successful implementation of Epley maneuvers. The initial measurement revealed a significantly reduced amplitude of oVEMP on the affected side. On the 7-day measurement, the amplitude increase was observed on the affected side, with significant reduction in the amplitude ratio (p=0.693), which reached statistical significance on the last measurement at 6 months (p=0.006). These findings confirmed the hypothesis of the return of otoconia into the utricular area.
