RESUMO

BACKGROUND: Patients with advanced cancer often face distressing decisions about chemotherapy. There are conflicting data on the relationships among perceived prognosis, psychological characteristics, and chemotherapy use, which impair the refinement of decision support interventions. OBJECTIVE: Clarify the relationships among patient and oncologist estimates of life expectancy for 6 and 12 months, chemotherapy use, and patient psychological characteristics. DESIGN: Secondary analysis of data from two cross-sectional studies. SETTING/SUBJECTS: One hundred sixty-six patients with advanced stage cancer recruited from ambulatory cancer clinics. MEASUREMENTS: All data were obtained at study enrollment. Patients completed the Adult Hope Scale, Hospital Anxiety and Depression Scale, and Life Orientation Test-Revised. Patients and their oncologists provided estimates of surviving beyond 6 and 12 months. Chemotherapy use was determined by chart review. RESULTS: There were no significant associations between life-expectancy estimates and chemotherapy use nor patient anxiety, depression, hope, or optimism and chemotherapy use. Patients' life expectancy estimates for 12 months and oncologists' for 6 months were associated with higher patient anxiety and depression. Finally, both oncologist and patient estimates of life expectancy for 6 and 12 months were associated with increased levels of trait hope. CONCLUSION: Advanced cancer patients who provide less optimistic estimates of life expectancy have increased anxiety and depression, but do not use chemotherapy more often. Increased patient trait hope is associated with more favorable oncologist estimates. These findings highlight the need for interventions to support both patients and oncologists as they clarify prognostic expectations and patients cope with the psychological distress of a limited life expectancy.

RESUMO

PURPOSE: More physicians need to acquire the skills of primary palliative care. Medical students' clerkship experiences with death, dying, and palliative care (DDPC), however, may create barriers to learning such skills during residency. Whether professional development is differentially affected by DDPC is unknown. This knowledge gap potentially hinders the development of educational strategies to optimize students' preparedness for primary palliative care. METHOD: Third-year students submitted professionalism narratives (N = 4062) during their internal medicine clerkship between 2004 and 2011. We identified DDPC-related narratives and then randomly selected control narratives. Narratives were compared by valence (positive or negative) and professionalism-related themes. RESULTS AND CONCLUSION: Less than 10% of the narratives were related to DDPC, but the majority was positive. There was a significant overlap in professionalism themes between DDPC and control narratives. The results suggest student preparedness for primary palliative care may be improved by addressing the common professionalism challenges of clinical clerkships.

RESUMO

Dynamic microtubules are necessary for proper mitotic spindle assembly and chromosome segregation during mitosis. Members of the kinesin superfamily of molecular motor proteins are important to spindle function. Of particular interest is the Kinesin-13 family member MCAK, which acts to regulate microtubule dynamics during spindle assembly and to ensure proper attachments of chromosomes to spindle microtubules. The unique ability of MCAK to regulate microtubule dynamics makes it a potential target for development of new drugs that alter spindle function. Here, we knocked down MCAK via RNAi in normal and malignant cell lines and found that the two tested malignant cell lines were acutely sensitive to MCAK knockdown, while the tested normal cells were less sensitive. In addition, we looked at the effect of combining MCAK knockdown and drug treatment with paclitaxel or vinblastine to identify spindle assembly defects. We found that MCAK knockdown increased the morphological defects of the microtubule cytoskeleton in HeLa cells caused by anti-microtubule drugs. Our studies support the idea that MCAK would be a good target for new chemotherapeutic development and may be particularly useful in combination therapies with currently available anti-microtubule agents.
