Scotland's relative mortality disadvantage compared to the rest of Great Britain, after allowing for deprivation, is worsening. By 1991 measures of deprivation no longer explained most of the excess mortality in Scotland and the unexplained excess has persisted during the 1990s. More research is required to understand what is causing this 'Scottish effect'.

This prospective descriptive study has analysed 214 patient interviews before and 1 year after coronary artery bypass grafting (CABG). The preoperative interview explored issues related to the impact of coronary artery disease upon health and expectations of benefit from the patients' perspective. The postoperative interview examined patients' accounts of the experience of operation and its impact on their health. A thematic analysis of the interview data was undertaken. The main factors relating to health status preoperatively were described in terms of 'dependency' on others and medication, and 'impending doom' of some major life threatening event. Benefits to health postoperatively were viewed in terms of 'removal of a death sentence' and 'freedom of choice'. Expectations of benefit from operation were varied and included 'freedom and independence', 'hope, chance and uncertainty' and 'addition of years to life and life to years'. Undergoing the operation was described by themes of the 'enormity of the experience' and 'the importance of lay support'. These findings provide a greater understanding of the 'lived experience' of both coronary artery disease and undergoing coronary artery bypass grafting. Unrealistic expectations of the benefits of CABG highlights the need for improvement in the way patients are informed about risks and benefits of interventions. In addition, the views and insights suggest that CABG operation is regarded as a significant major life event; thus more information, advice and counselling might help support patients before, during and after surgery.

The interrelationship between diarrhea, malnutrition, and small bowel integrity was investigated prospectively in 68 Gambian infants aged 0-18 mo. Profiles of growth and morbidity were recorded for 8 mo. Each month intestinal permeability was measured by the differential uptake of orally administered lactulose (L) and mannitol (M). In well infants the mean L:M ratio was 0.42 (range 0.11-1.42). This ratio was increased slightly for underweight (60-80% wt for age) infants (mean 0.52) but considerably for those with marasmus (less than 60% wt for age) (mean 1.3, p less than 0.001), for those with acute or chronic diarrhea (mean 1.0 and 2.85, respectively; p less than 0.001), or with measles (mean 1.4, p less than 0.001). Sequential studies of ward patients with malnutrition and diarrhea showed a rapid fall in L:M ratios with resolution of diarrhea. These studies suggest that damage to the small intestine may play an important part in the development of infant malnutrition in The Gambia.
