The evaluation of a palliative care programme for people suffering from life-limiting diseases.

AIMS AND OBJECTIVES: To report on the effectiveness of an eight-week palliative care programme in Hong Kong. BACKGROUND: A recent survey reported that the quality of palliative care services in Hong Kong ranked the 20th among 40 countries and it is far behind other Asian countries. There are disagreement and inadequate communication in clinical decision-making among patients, families and healthcare professionals, and that the nurses lack sufficient knowledge and skills in providing palliative care and advance care planning. DESIGN: A pretest post-test design and semi-structured interviews were adopted. METHODS: A total of 108 home care patients with life-limiting disease and their family caregivers in Hong Kong were recruited to complete a set of questionnaire including The McGill Quality of Life Questionnaire for Hong Kong Chinese and the Family Satisfaction Scale before and after they attended an eight-week programme. The programme comprised the elements of symptom management, intensive communication on advance care planning and psychosocial intervention. RESULTS: Pearson's chi-square tests and Wilcoxon matched paired tests show a general trend that the patients' quality of life was improved after the programme. Their understanding and active participation in advance care planning was also improved. The hospital readmission rate and the days of hospital stays were significantly reduced. In qualitative interview, four major themes were identified that are as follows: improvement in the communication of treatment plans and after-death arrangements, symptom management, emotional support and suggested areas of improvement. CONCLUSION: The study supports the benefit of implementing a palliative care programme to patients with life-limiting disease. Patients demonstrated improved understanding and changed behaviour as regards the preparation for death and dying after the eight-week programme. RELEVANCE TO CLINICAL PRACTICE: The programme could be replicated in other hospitals and infirmaries that offer home care services.

Competitive repair by naturally dispersed repetitive DNA during non-allelic homologous recombination.

Genome rearrangements often result from non-allelic homologous recombination (NAHR) between repetitive DNA elements dispersed throughout the genome. Here we systematically analyze NAHR between Ty retrotransposons using a genome-wide approach that exploits unique features of Saccharomyces cerevisiae purebred and Saccharomyces cerevisiae/Saccharomyces bayanus hybrid diploids. We find that DNA double-strand breaks (DSBs) induce NAHR-dependent rearrangements using Ty elements located 12 to 48 kilobases distal to the break site. This break-distal recombination (BDR) occurs frequently, even when allelic recombination can repair the break using the homolog. Robust BDR-dependent NAHR demonstrates that sequences very distal to DSBs can effectively compete with proximal sequences for repair of the break. In addition, our analysis of NAHR partner choice between Ty repeats shows that intrachromosomal Ty partners are preferred despite the abundance of potential interchromosomal Ty partners that share higher sequence identity. This competitive advantage of intrachromosomal Tys results from the relative efficiencies of different NAHR repair pathways. Finally, NAHR generates deleterious rearrangements more frequently when DSBs occur outside rather than within a Ty repeat. These findings yield insights into mechanisms of repeat-mediated genome rearrangements associated with evolution and cancer.

Relationships between culture and health status: a multi-site study of the older Chinese in Canada.

This study examined the relationships between culture and the health status of older Chinese in Canada. Data were collected through face-to-face interviews with a cross-sectional, randomly selected sample of 2,272 older Chinese between 55 and 101 years of age in seven Canadian cities. Health status was assessed by the number of chronic illnesses, by limitations in ADL and IADL, and by information on the Medical Outcome Study Short Form SF-36. Although cultural variables explained only a small proportion of variance in health status, having a stronger level of identification with traditional Chinese health beliefs was significant in predicting physical health, number of illnesses, and limitations on IADL. Other cultural variables, including religion, country of origin, and length of residence in Canada, were also significant in predicting some health variables. Interventions to improve health should focus on strategies to enhance cultural compatibility between users and the health delivery system.
