MATERIALS AND METHODS: A cross-sectional study through a purposive sampling method was employed, involving 142 caregivers of CWD at the selected CBR centre. Four CBR centres were selected in this study, which were located in the Kudat division of Sabah. The Malay version of the Modified Caregiver Strain Index Questionnaire (M-CSI-M) was used in this study to obtain information about the caregiver's strain.
RESULTS: Findings from this study revealed that most caregivers experienced moderate strain (72.5%). Some of the leading causes of their strain were upsetting CWD's behaviour (10.6%), financial strain (9.2%), and overwhelmed (9.2%). In addition, there were significant differences between caregiver strain and their level of education, income, and the types of their child's disabilities (p ≤ 0.05).
CONCLUSION: The well-being of the caregivers may significantly impact the effectiveness of rehabilitation for CWD, as caregivers are vital interdisciplinary team members.
Methods: This study was carried out at the Universiti Kebangsaan Malaysia, Kuala Lumpur, Malaysia, between June 2016 and July 2017. Bone marrow cells were isolated from nine mice and cultured in a growth medium. Various concentrations of NAC between 0.125-2 μM were added to the culture for 48 hours; these cells were then compared to non-supplemented cells harvested from the remaining three mice as the control group. A trypan blue exclusion test was performed to determine cell viability, while intracellular ROS levels and genotoxicity were determined by hydroethidine staining and comet assay, respectively. The lineage commitment potential of erythroid, myeloid and pre-B-lymphoid progenitor cells was evaluated via colony-forming cell assay.
Results: NAC supplementation at 0.25, 0.5 and 2 μM significantly increased cell viability (P <0.050), while intracellular ROS levels significantly decreased at 0.25 and 0.5 μM (P <0.050). Moreover, DNA damage was significantly reduced at all NAC concentrations (P <0.050). Finally, the potential lineage commitment of the cells was not significantly affected by NAC supplementation (P >0.050).
Conclusion: The findings of this study indicate that NAC supplementation may potentially overcome the therapeutic limitations of ex vivo-maintained HSPCs.
