RESUMEN

BACKGROUND: Our aim was to systematically review prospective studies of the association of plasma adiponectin levels with the risk of coronary heart disease (CHD) events, cardiovascular mortality and all-cause mortality. METHODS: We searched Medline, EMBASE, the Cochrane Library and CINAHL for reports published through October 2011. Search terms included 'adiponectin' AND 'cardiovascular disease' OR 'mortality'. We included prospective studies lasting more than 1 year with plasma adiponectin levels at baseline and all-cause mortality and/or major cardiovascular morbidity and mortality as outcomes. We used a random-effects model to pool the data and conducted additional subgroup meta-analyses according to the pre-existence of CHD. Pooled relative risk (RR) was estimated by a 1-SD increase in the logarithmically transformed circulating adiponectin levels. RESULTS: A total of 24 prospective studies were included in the meta-analysis. The pooled RR of adiponectin for CHD events (23 studies) was 1.03 [95% confidence interval (CI): 1.00, 1.06]. In subgroup analyses, the RR of adiponectin was 0.99 (95% CI: 0.94, 1.03) for new-onset CHD (17 studies), but there was an increased risk (RR = 1.12, 95% CI: 1.04, 1.22) for CHD recurrence (seven studies). A 10% increased risk (RR = 1.10, 95% CI: 1.04, 1.16) of all-cause mortality (six studies) and a 14% increased risk (RR = 1.14, 95% CI: 1.05, 1.23) of cardiovascular disease mortality (five studies) were observed. CONCLUSIONS: No association was observed between adiponectin levels and CHD events. Our results suggest that higher circulating adiponectin levels may be associated with an increased risk of CHD recurrence and all-cause/CVD mortality.

RESUMEN

PURPOSE: The debate about the end-of-life care decision is becoming a serious ethical and legal concern in the Far-Eastern countries of Korea, China and Japan. However, the issues regarding end-of-life care will reflect the cultural background, current medical practices and socioeconomic conditions of the countries, which are different from Western countries and between each other. Understanding the genuine thoughts of patients who are critically ill is the first step in confronting the issues, and a comparative descriptive study of these perspectives was conducted by collaboration between researchers in all three countries. METHODS: Surveys using self-reporting paper questionnaire forms were conducted from December 2008 to April 2009 in Korea (six hospitals in two regions), China (five hospitals in four regions) and Japan (nine hospitals in one region). The subjects were patients who were critically ill who had been diagnosed as having cancer. A total of 235 participants (Korea, 91; China, 62; Japan, 52) were eventually recruited and statistically analysed. RESULTS: Most respondents had sometimes or often thought of their own death, mostly fear of 'separation from loved ones'. They wanted to hear the news regarding their own condition directly and frankly from the physician. A quarter of them preferred making end-of-life care decisions by themselves, while many respondents favoured a 'joint decision' with their family members. The most favoured proxy decision maker was the spouse, followed by the children. Most admitted the necessity of 'advance directives' and agreed with artificial ventilation withdrawal in irreversible conditions. The most common reason was 'artificial prolongation of life is unnecessary'. Most respondents agreed with the concept of active euthanasia; however, significant differences were sometimes observed in the responses according to variables such as patient's country of origin, age, gender and education level. CONCLUSION: Patients in Far-Eastern countries gave various responses regarding end-of-life care decisions. Although familial input is still influential, most patients think of themselves as the major decision maker and accept the necessity of advance directives with Westernization of the society. Artificial ventilation withdrawal and even active euthanasia may be acceptable to them.

RESUMEN

This study aimed to test the reliability and validity of the Korean version of McGill Quality of Life Questionnaire (MQOL-K) for use with 140 palliative care patients in Korea. Our results confirmed the suitability of using the 16 questions of the questionnaire clustered into four domains (physical, psychological, existential and support) as in the original version of the MQOL, although the distribution of items among the domains differed somewhat from the original. The MQOL-K demonstrated moderate to high internal consistency (Cronbach's alpha, 0.62-0.90), convergent validity without scaling error, and a good concurrent validity with European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30, sense of dignity, and general health perception. In addition, we tested the clinical validity of the MQOL-K using a known group comparison to quantify sensitivity. Regression results indicated that the existential and psychological domains had independent effects on the overall quality of life of patients in Korea. Therefore, the MQOL-K is deemed suitable for assessing the quality of life in a Korean palliative care setting.
