The daily dynamics of loss orientation and life engagement in advanced cancer: A pilot study to characterise patterns of adaptation at the end of life.

Individual adaptation at the end of life may be characterised by how patients fluctuate in their orientation towards losses and death or engagement in meaningful activities in daily life. To describe these intraindividual patterns of change, we conducted a daily diary study over 7 days with 17 advanced cancer patients from in- and outpatient oncology and psycho-oncology clinics. Patients reported on the daily frequency of behaviours associated with loss orientation and life engagement using a standardised questionnaire. We characterised each patient's pattern of change with three parameters: the mean level (5-point-scale from 0 = never to 4 = always), mean fluctuation between successive days (MSSD) and the association between changes in loss and life orientation over time. We further explored the relationship between these patterns and free-text diaries. The daily assessment protocol was acceptable and feasible (46% participation rate, 97% diary completion rate). Individuals differed in mean levels of loss orientation (range: M = 0.1 to 2.7) and life engagement (M = 0.9 to 3.9), the degree of fluctuation (MSSD = 0.1 to 1.5 and MSSD = 0.3 to 0.9), and the correlations between these changes over time (r = -.83 to +.46), revealing distinctive intraindividual patterns. Further study of individual profiles in loss and life orientation can promote personalised balancing between facing "reality" and sustaining "hope" in end-of-life conversations.

Sources of meaning in cancer patients - influences on global meaning, anxiety and depression in a longitudinal study.

Although existential needs are highly prevalent in patients with cancer, specific sources of meaning have been little explored. We investigated whether specific sources of meaning predict global meaning and psychological distress. N = 258 patients with breast (45%), lung (39%) and gynaecological cancer (16%) completed a battery of validated questionnaires at T1. Six months later (T2), n = 183 (78%) patients participated again. The primary outcomes - sources of meaning, global meaning and psychosocial distress - were measured with the Sources of Meaning Profile-Revised (SOMP-R), Life Attitude Profile-Revised (LAP-R) and modules for depression and anxiety of the Patient Health Questionnaire (PHQ-9, GAD-7). Most important sources of meaning were 'engaging in personal relationships', 'preserving human values and ideals' and 'feeling financially secure'. Stepwise multivariate regression analyses controlling for demographic and medical factors revealed that 'engaging in personal relationships', 'preservation of culture and tradition' and 'interest in social and/or political causes' predicted lower depression. 'Leaving a legacy for the next generation' and 'feeling financially secure' predicted both higher depression and anxiety. The findings highlight the relevance of sources of meaning for the psychological well-being of cancer patients and point towards specific sources of meaning that should be focused in psychosocial interventions.

A reproducible procedure for primary culture and subsequent maintenance of multiple lines of human skin fibroblasts.

Cultured fibroblasts are a valuable tool to study many cellular processes and their modification by aging. Fibroblasts are a useful cell type in which to study many diseases, including those of the nervous system, in which a strong genetic component is suspected. Fibroblasts permit the study of multiple, dynamic processes in living cells, while avoiding the effect of the dying process and post-mortem artifacts that limit other approaches. For results to be comparable across time in one laboratory or consistent between laboratories, the detailed culture techniques require meticulous care and replicability. Lack of attention to detail in initial stages can lead to selection of different cell populations. Small variations in othe variables such as batches of serum can significantly alter growth rates and comparisons of cells from controls and Alzheimer patients. The aim of this paper is to present a detailed protocol for comparison of multiple cell lines from many patients. An example of using this approach to study growth and phase out (i.e., senescence) of cells from Alzheimer patients is presented. This procedure represents a modification of an earlier protocol (Cristofalo and Charpentier, 1980).
