Interleukin 2 and interleukin 15 differentially predispose natural killer cells to apoptosis mediated by endothelial and tumour cells
Human natural killer (NK) cells constitutively express the beta- and gamma-chains of the interleukin 2 (IL-2)/IL-15 receptor, and both IL-2 and IL-15 are able to activate NK cell proliferation and cytotoxicity. When IL-2-primed human NK cells are exposed to sensitive targets (i.e. K562) they undergo apoptosis mediated by the beta(2)-integrin CD18. Here, we demonstrate that: (i) endothelial cells, similar to K562 tumour target cells, induce apoptosis of IL-2-primed NK cells; (ii) endothelial- and K562 cell-induced apoptosis is significantly lower in IL-15 than in IL-2-stimulated NK cells; (iii) a critical role in the apoptosis of IL-2-primed NK cells is played by the alpha-chain of the IL-2 …
Inequity in palliative care service full utilisation among patients with advanced cancer: a retrospective Cohort study.
Background: Advanced cancer patients often die in hospital after receiving needless, aggressive treatment. Although palliative care improves symptom management, barriers to accessing palliative care services affect its utilisation, and such disparities challenge the equitable provision of palliative care. This study aimed to identify which factors are associated with inequitable palliative care service utilisation among advanced cancer patients by applying the Andersen Behavioural Model of Health Services Use.Material and methods: This was a retrospective cohort study using administrative healthcare data. A total of 13,656 patients residing in the Lazio region of Italy, who died of an advan…
Validity and reliability of the Palliative Care Transition Measure for Caregivers (PCTM-C).
AbstractObjectivePatients suffering from advanced disease face different care transitions. The transition from acute to palliative care is challenging and may lead to the discontinuity of care. Family caregivers become important sources of information, as patients begin to experience difficulties in coping with emotional transition events. The Care Transition Measure was developed to evaluate care transitions as experienced by the elderly. It has never been used in palliative care. The aim of this study was to test the validity and reliability of a modified version of the Palliative Care Transition Measure, specifically the Palliative Care Transition Measure for Caregivers (PCTM-C).MethodTh…
