RESUMEN
Identity development within the interprofessional field is an emerging area of research. This scoping review aims to establish how professional and interprofessional identities are defined, conceptualized, theorized and measured within the interprofessional literature. Six databases were systematically searched for papers focusing on professional and/or interprofessional identities in interprofessional healthcare and education using a scoping review methodology. A total of 84 papers were included. Most papers discussed professional identity only; the minority discussed both identities. There were three key findings. First, no universal definition of interprofessional identity exists. Second, there is no shared understanding of interprofessional identity and its relationship with professional identity. Third, poor alignment between definitions, conceptualizations, theories and measures of interprofessional identity exists. The absence of a psychometrically robust instrument that specifically measures interprofessional identity and the short-term focus of current interprofessional identity research further limits understanding. Research that critically examines professional and interprofessional identity development should be underpinned by clear definitions, concepts, theories and measures of both identities. High-quality research will allow greater understanding of interprofessional identity development and its impact on interprofessional practice.
RESUMEN
The strength of health science students' identification with their chosen profession is associated with their attitudes towards interprofessional education (IPE). However, little is known about the factors that might mediate this relationship. In this article, we examine the relationships between professional identification, communication and teamwork skills, perceived relevance of IPE, and positive and negative attitudes towards IPE. A sample of 444 first-year university students from 25 health science professions enrolled in a first-year interprofessional program participated in this research by completing a questionnaire. Data were analysed using path analysis. Positive IPE attitudes were more strongly endorsed than negative IPE attitudes. Perceived relevance of IPE to future careers was the strongest predictor of both positive and negative attitudes to IPE, and fully mediated the effect of professional identity. Self-reported communication and teamwork skills were a significant negative predictor of negative attitudes to IPE only, and the effect was not mediated by perceived relevance. These findings indicate that IPE may be particularly challenging for students who do not have confidence in their abilities to communicate and work effectively in teams. Building these skills through alternative communication technologies may decrease negative attitudes. In order to maintain or increase positive attitudes towards IPE in introductory programs that span professions, the curriculum needs to be designed to demonstrate relevance to the future careers of participating students.

BACKGROUND: The metabolic pathways associated with colonic motility are unknown. To identify potential metabolic targets for treatment of constipation, we examined the metabolic profile before and after a meal challenge in a cohort of children with constipation and determined its relationship with postprandial colon motility patterns. METHODS: In this prospective study, 187 metabolites were measured by liquid chromatography-mass spectrometry at multiple time points before and after a standardized meal in constipated children undergoing a colon manometry. Postprandial metabolite levels were compared with baseline and also correlated with multiple manometric measurements, including the number, frequency, and amplitude of pressure peaks as well as the motility index (MI). KEY RESULTS: A total of 20 subjects were included (mean age 13.1 ± 3.4 years). No significant metabolite changes were observed at 10 min after the meal, whereas 16 amino acid and 22 lipid metabolites had significant (P < 0.005) postprandial changes, including decreases in methylhistamine, histamine, and GABA, by 60 min. Correlations were observed between normal and abnormal postprandial motility patterns and changes in specific metabolites, including glycerol, carnosine, alanine, asparagine, cytosine, choline, phosphocholine, thyroxine, and triiodothyronine. Interestingly, subjects without the normal postprandial increase in area under the curve (AUC), had markedly increased levels of kynurenic acid and adenosyl-homocysteine. CONCLUSIONS & INFERENCES: This is the first study to examine postprandial metabolic changes in children and also to correlate changes in specific metabolites with colonic motility. The results suggest possible metabolic pathways associated with motility and identify potential targets for the treatment of constipation.

Recent work from this laboratory both in rat primary cardiomyocytes and in ventricular tissue of transgenic mouse models of induced hypertrophy has identified two Ca(2+)/calmodulin-dependent nuclear signaling cascades. The first involves the phosphatase calcineurin (CaN). The second is the CaM kinase kinase cascade which involves CaM kinase I and CaM kinase IV. Each of these signaling cascades strongly up-regulate transcription of hypertrophy-sensitive genes in the rat ventricular cardiomyocyte. We have documented that over-expression of an active form of CaM kinase II silenced transcriptional induction of hypertrophy-sensitive genes. The purpose of this study was to generate an inducible CaM kinase II expression system and correlate its expression with the silencing of hypertrophic-sensitive reporters. A truncated form of CaM KII, CaM KII (1-290) was subcloned downstream and proximal to a promoter under transcriptional control (induction) of the tetracycline-regulated transcription factor, tet-TransActivator (tTA). Hypertrophy-sensitive reporter activity in primary cardiomyocytes was silenced when tet-inducible CaM KII was co-expressed with plasmids harboring active forms of CaN, CaM KI or CaM KIV. For instance, induced CaM KII expression silenced CaN, CaM kinase I, or CaM kinase IV driven ANF reporter activity 4.9-, 2.9-, and 6.9-fold below their maximal values, respectively. Myocyte exposure to doxycycline (DOX) blocked tTA-driven CaM KII expression and restored CaN/CaM KI or CaN/CaM KIV driven reporter activation. This study demonstrates, for the first time, that active CaM KII silences Ca(2+)-sensitive nuclear signaling cascades for transcriptional up-regulation of cardiomyocyte hypertrophy.
