Effective interprofessional working, which is widely considered as essential to high-quality health care, is influenced by the attitudes of health care professionals towards their own and other professional groups. Relatively little is known, however, about interprofessional attitudes, particularly of students in health care professions. This study aimed to increase our understanding of students' attitudes towards their own and other professional groups on entry to a programme of professional education. Hypothesised relationships between stereotypes, professional identity and readiness for professional learning were tested by means of a questionnaire survey of 933 undergraduate health care students drawn from five health care groups (medicine, nursing, dietetics, pharmacy and physiotherapy) within a multi-faculty UK university. Positive statistically significant correlations were found between stereotypes, professional identity and readiness for interprofessional learning. As predicted, students identified strongly with their own professional group at the start of pre-registration education. They were also willing to engage in interprofessional learning. More unexpected was the positive association found between heterostereotype and professional identity scores. There are potential benefits of introducing active interprofessional education activities at an early stage of professional preparation to capitalise on students' positive attitudes towards their own and other professional groups.

The intestinal microbiota are a complex ecosystem influencing the immunoregulation of the human host, providing protection from colonising pathogens and producing SCFA as the main energy source of colonocytes. Our objective was to investigate the effect of dietary fibre exclusion and supplementation on the intestinal microbiota and SCFA concentrations. Faecal samples were obtained from healthy volunteers before and after two 14 d periods of consuming formulated diets devoid or supplemented with fibre (14 g/l). The faecal microbiota were analysed using fluorescent in situ hybridisation and SCFA were measured using GLC. There were large and statistically significant reductions in the numbers of the Faecalibacterium prausnitzii (P < or = 0.01) and Roseburia spp. (P < or = 0.01) groups during both the fibre-free and fibre-supplemented diets. Significant and strong positive correlations between the proportion of F. prausnitzii and the proportion of butyrate during both baseline normal diets were found (pre-fibre free r 0.881, P = 0.001; pre-fibre supplemented r 0.844, P = 0.002). A significant correlation was also found between the proportional reduction in F. prausnitzii and the proportional reduction in faecal butyrate during both the fibre-free (r 0.806; P = 0.005) and the fibre-supplemented diet (r 0.749; P = 0.013). These findings may contribute to the understanding of the association between fibre, microbiota and fermentation in health, during enteral nutrition and in disease states such as Crohn's disease.

The intestinal microbiota are important during enteral tube feeding because they exert colonization resistance and produce SCFAs. However, the effect of the enteral formula composition on major bacterial groups of the microbiota has not been clearly defined. The aim of this study was to investigate the effect of enteral formulas with and without prebiotic fructooligosaccharides (FOS) and fiber on the fecal microbiota and SCFAs. Healthy subjects (n = 10; 4 men, 6 women) consumed both a standard enteral formula and one containing FOS (5.1 g/L) and fiber (8.9 g/L) as a sole source of nutrition for 14 d in a randomized, double-blind, crossover trial with a 6-wk washout phase. Fecal samples were collected at the start and end of each formula phase, and were analyzed for major bacterial groups and SCFA concentrations using fluorescent in situ hybridization and GLC, respectively. Although there were reductions in total fecal bacteria due to both formula treatments, concentrations were higher after the FOS/fiber formula period compared with the standard formula period (11.2 +/- 0.2 vs. 11.0 +/- 0.2 log(10) cells/g, P = 0.005). The FOS/fiber formula increased bifidobacteria (P = 0.004) and reduced clostridia (P = 0.006). Compared with the standard formula, the FOS/fiber formula resulted in higher concentrations of total SCFA (332.4 +/- 133.8 vs. 220.1 +/- 124.5 micromol/g, P = 0.022), acetate (219.6 +/- 96.3 vs. 136.8 +/- 74.5 micromol/g, P = 0.034) and propionate (58.4 +/- 37.4 vs. 35.6 +/- 25.5 micromol/g, P = 0.02). This study demonstrates that standard enteral formula leads to adverse alterations to the fecal microbiota and SCFA concentrations in healthy subjects, and these alterations are partially prevented by fortification of the formula with FOS and fiber.

The present study examined age differences in the discrimination between anxiety and depressive symptoms in a community sample of 374 adults, ages 18-93. Older adults were less accurate and more likely than younger adults to label symptoms as neither anxiety nor depression. Both older and younger adults were more accurate in their classification of depressive than anxiety symptoms. These findings suggest that additional efforts are needed to educate the general public, particularly older adults, about anxiety and its symptoms.

The authors examined the relationship between anxiety, depression, and physical disability, after controlling for demographic and health variables, in a sample of 374 adults ages 18-94. Results indicate that anxiety, depression, and comorbid anxiety and depression are associated with higher levels of disability, after controlling for factors such as age, gender, income, self-rated health, number of medical conditions, and number of physician visits in the past year. Furthermore, anxiety, depression, and comorbid anxiety and depression have a differential effect on disability according to age, with older adults with any of these symptoms reporting higher levels of disability than younger adults. These findings suggest that physicians working with older adults should assess for and treat anxiety as well as depressive symptoms.Anxiety, depression, and physical disability are three major problems faced by many older adults, and there is growing evidence that these problems are related. Many studies have demonstrated that depressive symptoms are related to disability and poorer recovery from medical incidents independent of the increased medical burden experienced by depressed adults (for a review, see Lenze et al., 2001). However, surprisingly little research has examined the relationship between anxiety symptoms and disability.Research has suggested that anxiety symptoms and disorders may be as disabling as depression (Kessler et al., 1999;Massion, Warshaw, & Keller, 1993;Ormel et al., 1994;Wetherell et al., 2004). Nonetheless, only a handful of studies have examined the relationship between anxiety and disability. Based on these studies, anxiety symptoms appear to be associated with increased levels of disability among older adults with medical comorbidities. With the exception of Brenes et al. (2005), however, these studies did not examine the impact of anxiety on disability independent of depressive symptoms. Because anxiety and depressive symptoms are frequently comorbid, especially in older adults, it is important to determine if anxiety is a risk factor for disability independent of depression. One study provides evidence that anxiety is a predictor of the progression of disability, supporting the further study of anxiety. A second limitation of these studies is the small age range of the sample. Studies have focused on either adults or older adults, rather than taking a lifespan approach. No research to date has examined whether disability is more strongly related to anxiety or depression in older adults than in younger adults. Because disability is a more normative or expected experience in older people than in younger people and there are many competing somatic conditions, it is possible that disability in late-life is less strongly associated with anxiety and depressive symptoms. Conversely, since disability in older adults is often associated with increasing dependence and institutional placement, this may result in higher levels of anxiety or depression for older adults facing disability.The pur...
