    Background: The cost of caring for patients and their families in the midst of interconnected resource, ethical, moral, legal and practical considerations compromises a physician's emotional and physical well-being and therefore patient care. Whilst the cost of caring is historically best associated with compassion fatigue, data has suggested that this may extend to other related concepts, such as vicarious trauma, secondary traumatic stress and burnout. In particular, palliative care physicians are especially vulnerable as they witness and encounter more cases of death and dying. Methods: This study aims to provide a more clinically relevant notion of the cost of caring amongst palliative care physicians in Malaysia. 11 physicians underwent semi-structured interviews as part of the Systematic Evidence-Based Approach (SEBA) for prospective studies. Results: Analysis of the interview transcripts revealed the following domains: (1) conceiving the costs of caring; (2) risk factors; and (3) support mechanisms. Conclusion: This SEBA-guided study into the cost of caring amongst Malaysian palliative care physicians suggests that the costs of caring extend beyond encapsulating moral distress, compassion fatigue, vicarious trauma, secondary traumatic stress and burnout. Rather, the data suggests a personalized notion that varies with individual and contextual factors which are in flux and change over time. A longitudinal, personalized and holistic mentoring program is therefore proposed to counter this cost.

    Obesity is strongly linked with increased risk and poorer prognosis of endometrial cancer (EC). Cancer-associated fibroblasts (CAFs) are activated fibroblasts that form a large component of the tumor microenvironment and undergo metabolic reprogramming to provide critical metabolites for tumor growth. However, it is still unknown how obesity, characterized by a surplus of free fatty acids drives the modifications of CAFs lipid metabolism which may provide the mechanistic link between obesity and EC progression. The present study aims to evaluate the utility of Raman spectroscopy, an emerging nondestructive analytical tool to detect signature changes in lipid metabolites of CAFs from EC patients with varying body mass index. We established primary cultures of fibroblasts from human EC tissues, and CAFs of overweight/obese and nonobese women using antibody-conjugated magnetic beads isolation. These homogeneous fibroblast cultures expressed fibroblast markers, including α-smooth muscle actin and vimentin. Analysis was made in the Raman spectra region best associated with cancer progression biochemical changes in lipids (600-1800 cm-1 and 2800-3200 cm-1). Direct band analysis and ratiometric analysis were conducted to extract information from the Raman spectrum. Present results demonstrated minor shifts in the CH2 symmetric stretch of lipids at 2879 cm-1 and CH3 asymmetric stretching from protein at 2932 cm-1 in the overweight/obese CAFS compared to nonobese CAFs, indicating increased lipid content and a higher degree of lipid saturation. Principal component analysis showed that CAFs from overweight/obese and nonobese EC patients can be clearly distinguished indicating the capability of Raman spectroscopy to detect changes in biochemical components. Our results suggest Raman spectroscopy supported by chemometric analysis is a reliable technique for characterizing metabolic changes in clinical samples, providing an insight into obesity-driven alteration in CAFs, a critical stromal component during EC tumorigenesis.
