Introduction: Quality of life is included in the economic evaluation of health services by measuring the preference for health states, i.e. health state utilities. However, most intervention studies include a disease-specific, not a utility, instrument. Consequently, there has been increasing use of statistical mapping algorithms which permit utilities to be estimated from a disease-specific instrument. The present paper provides such algorithms between the MacNew Heart Disease Quality of Life Questionnaire (MacNew) instrument and six multi-attribute utility (MAU) instruments, the Euroqol (EQ-5D), the Short Form 6D (SF-6D), the Health Utilities Index (HUI) 3, the Quality of Wellbeing (QWB), the 15D (15 Dimension) and the Assessment of Quality of Life (AQoL-8D). Methods: Heart disease patients and members of the healthy public were recruited from six countries. Non-parametric rank tests were used to compare subgroup utilities and MacNew scores. Mapping algorithms were estimated using three separate statistical techniques. Results: Mapping algorithms achieved a high degree of precision. Based on the mean absolute error and the intra class correlation the preferred mapping is MacNew into SF-6D or 15D. Using the R squared statistic the preferred mapping is MacNew into AQoL-8D. Implications for research: The algorithms reported in this paper enable MacNew data to be mapped into utilities predicted from any of six instruments. This permits studies which have included the MacNew to be used in cost utility analyses which, in turn, allows the comparison of services with interventions across the health system.

Some research suggests that the risk of physical aggression by an intimate partner is related to marital status, but this relationship may vary across cultures and by gender. In the present study, we systematically examine the relationship between marital status and physical partner aggression by gender across 19 countries. Logistic and multilevel regression confirmed previous findings of lower rates of physical aggression for legally married versus cohabiting and separated/divorced women and men across most, but notably, not all countries. Single status was associated with higher risk in some countries and lower in others reflecting possible cultural differences in risk for different marital statuses. For example, single women had significantly lower rates of victimization than did married women in India where violence against wives is often accepted. The variation in the cross-cultural findings highlights the importance of examining both men and women and considering the cultural context when interpreting the relationship between partner aggression and marital status.

J Hum Nutr Diet. 25, 388-397 Abstract Background: Many guidelines exist for the nutritional management of acute pancreatitis; however, little is known regarding current practice. We aimed to investigate feeding practices, including the use of parenteral/enteral nutrition. Methods: The study design was a cross-sectional, descriptive survey. Electronic surveys were sent to dietitians in the UK, the Republic of Ireland and Canada. Of 253 dietitians surveyed, 204 saw patients with acute pancreatitis regularly or occasionally and were included in the analyses. Results: Most dietitians (92.8%) considered early feeding to mean <48 h after presentation. Over half (54.2%) favoured early feeding in severe disease, less in obesity (42%) and more with pre-existing malnutrition (81.9%). There was a tendency to feed earlier in university hospitals ( P = 0.015), especially in obesity ( P = 0.011). There was a tendency towards enteral (versus parenteral) nutrition in university hospitals ( P = 0.000). The majority preferred the jejunal route (64.2%), although this was lower in the UK (43.8%) than in Canada (77.8%) or Ireland (54.2%). Under one-quarter of UK dietitians (23.2%) reported the existence of a pancreatic multidisciplinary team in their institutions, although this was lower in Ireland and Canada. Conclusions: Despite guidelines, there are gaps in the nutritional management of acute pancreatitis, including a continued reliance on parenteral feeding. [ABSTRACT FROM AUTHOR]
