Safety of Care by Caregivers of Cancer Patients

Caregiving Ability of Mothers of Children With Cancer: Qualitative Content Analysis

BACKGROUND

Childhood cancer confronts the child and the parents with considerable degrees of stress. Because caring for the child is mainly the role of the mother in most families, her ability to take care of the affected child is very important.

OBJECTIVE

To explore the caregiving ability of Iranian mothers who have children diagnosed with cancer.

METHODS

In this present study, which was conducted using the Directed Qualitative Content Analysis Method, 11 parents having children diagnosed with cancer and 5 professional caregivers working at the Department of Hematology and Oncology of Mofid Children Hospital in Tehran, Iran, were selected using purposeful sampling method. Data were collected through semistructured interviews. Data analysis was performed simultaneously with data collection using the Directed Content Analysis Approach.

RESULTS

Five main categories emerged, namely, care exhaustion, care confusion, spiritual conflict, care competence, and care preparedness that represent the beneficiaries' perception of the caring ability of Iranian mothers of cancer-afflicted children.

CONCLUSION

Study results revealed that the caregiving capacity of mothers nurturing cancer-stricken children can be evaluated across 5 domains, encompassing a spectrum of maternal requirements in child care. Improving these domains can elevate maternal caregiving proficiency, fostering self-care and enhancing care for the ailing child.

IMPLICATION FOR PRACTICE

A program can be developed based on the findings of the present study, in order to improve the caring ability of mothers of cancer-afflicted children, which results in improving the mother's care for her cancer-afflicted child.

Prolonged sub-lethal exposure to galaxolide (HHCB) and tonalide (AHTN) promotes the metastatic potential of glioblastoma tumor spheroids

Galaxolide and tonalide are well-known polycyclic musks whose intensive use without limitations in numerous cleaning, hygiene, and personal care products has resulted in widespread direct human exposure via absorption, inhalation, and oral ingestion. Latest data shows that long-term, low-dose exposure to toxic chemicals can induce unpredictable harmful effects in a variety of living systems, however, interactions between synthetic musks and brain tumours remain largely unexplored. Glioblastoma (GB) accounts for nearly half of all tumours of the central nervous system and is characterized by very poor prognosis. The aims of this study were (1) to investigate the potential effect of long-term (20-generation) single and combined application of galaxolide and tonalide at sub-lethal doses (5-2.5 u M) on the angiogenesis, invasion, and migration of human U87 cells or tumour spheroids, and (2) to explore the underlying molecular mechanisms. Random amplified polymorphic DNA assays revealed significant DNA damage and increased total mutation load in galaxolide- and/or tonalide-treated U87 cells. In those same groups, we also detected remarkable tumour spheroid invasion and up-regulation of both HIF1-α/VEGF/MMP9 and IL6/JAK2/STAT3 signals, known to have important roles in hypoxia-related angiogenesis and/or proliferation. Prolonged musk treatment further altered angio-miRNA expression in a manner consistent with poor prognosis in GB. We also detected significant over-expression of the genes Slug, Snail, ZEB1, and Vimentin, which are biomarkers of epithelial to mesenchymal transition. In addition, matrigel, transwell, and wound healing assays clearly showed that long-term sub-lethal exposure to galaxolide and/or tonalide induced invasion and migration proposing a high metastatic potential. Our results suggest that assessing expression of HIF-1a, VEGF, STAT3, and the miR-17-92 cluster in biopsy samples of GB patients who have a history of possible long-term exposure to galaxolide or tonalide could be beneficial for deciding a therapy regime. Additionally, we recommend that extensively-used hygiene and cleaning materials be selected from synthetic musk-free products, especially when used in palliative care processes for GB patients.
