Assessment of the Perception of Symptoms and Anxiety in Terminally Ill Patients in Spain

Mitochondrial glutathione depletion by glutamine in growing tumor cells.

The effect of L-glutamine (Gln) on mitochondrial glutathione (mtGSH) levels in tumor cells was studied in vivo in Ehrlich ascites tumor (EAT)-bearing mice. Tumor growth was similar in mice fed a Gln-enriched diet (GED; where 30% of the total dietary nitrogen was from Gln) or a nutritionally complete elemental diet (SD). As compared with non-tumor-bearing mice, tumor growth caused a decrease of blood Gln levels in mice fed an SD but not in those fed a GED. Tumor cells in mice fed a GED showed higher glutaminase and lower Gln synthetase activities than did cells isolated from mice fed an SD. Cytosolic glutamate concentration was 2-fold higher in tumor cells from mice fed a GED ( approximately…

Palliative Care Professionals' Inner Life: Exploring the Relationships Among Awareness, Self-Care, and Compassion Satisfaction and Fatigue, Burnout, and Coping With Death

Context. Professionals working in the landscape of death and dying frequently are exposed to existential issues, psychological challenges, and emotional distress associated with care at the end of life. Identifying factors that help professionals cope with frequent exposure to issues related to mortality could enhance palliative care providers' and patients' quality of life. Objectives. To improve our understanding of the factors associated with professionals' inner life, through the assessment of an adapted version of Kearney and Kearney's awareness model of self-care. The main assumptions of the study were that competence in coping with death and awareness would be positively related to c…

Development and Validation of a New Tool for the Assessment and Spiritual Care of Palliative Care Patients

Context. Spiritual assessment tools and interventions based on holistic approaches are needed to promote healing. Such tools must be adapted to the wide cultural backgrounds of contemporary Western society. Objectives. To develop and validate a new brief measure, simultaneously featuring clinical applicability and adequate psychometric properties. The tool uses six initial questions to establish a climate of trust with patients before they complete an eight-item, five-point Likert scale. The questionnaire is based on a model of spirituality generated by the Spanish Society of Palliative Care (SECPAL) Task Force on Spiritual Care (Grupo de Espiritualidad de la SECPAL), which aims to recogniz…

Glutamine potentiates TNF-α-induced tumor cytotoxicity

L-glutamine (Gln) sensitizes tumor cells to tumor necrosis factor (TNF)-alpha-induced cytotoxicity. The type and mechanism of cell death induced by TNF-alpha was studied in Ehrlich ascites tumor (EAT)-bearing mice fed a Gln-enriched diet (GED; where 30% of the total dietary nitrogen was from Gln). A high rate of Gln oxidation promotes a selective depletion of mitochondrial glutathione (mtGSH) content to approximately 58% of the level found in tumor mitochondria of mice fed a nutritionally complete elemental diet (standard diet, SD). The mechanism of mtGSH depletion involves a glutamate-induced inhibition of GSH transport from the cytosol into mitochondria. The increase in reactive oxygen in…

Spirituality in patients with advanced illness: The role of symptom control, resilience and social network.

In this study, we analyzed the relationships among clinical, emotional, social, and spiritual dimensions of patients with advanced illness. It was a cross-sectional study, with a sample of 108 patients in an advanced illness situation attended by palliative care teams. Statistically significant correlations were found between some dimensions of spirituality and poor symptomatic control, resiliency, and social support. In the structural model, three variables predicted spirituality: having physical symptoms as the main source of discomfort, resiliency, and social support. This work highlights the relevance of the relationships among spirituality and other aspects of the patient at the end o…
