Fostering collaborative practice through interprofessional simulation for occupational therapy, physiotherapy, dietetics, and nursing students.

Literature regarding simulation for learning interprofessional collaborative practice (IPCP) indicates a need to include a range of health professions and to focus on students' development of team communication and conflict resolution skills in day-to-day healthcare delivery. This study evaluated the impact of interprofessional simulation for occupational therapy, physiotherapy, dietetics, and nursing students on interprofessional collaboration competencies, specifically collaborative communication and conflict resolution during day-to-day interactions, and their intention for IPCP during placement. A series of simulations featuring the potential for interprofessional conflict and involving explicit coaching on communication and conflict resolution were conducted. A single cohort pre-test post-test design included the Students' Perceptions of Interprofessional Clinical Education Revised (SPICE-R), the Interprofessional Collaborative Competencies Attainment Survey (ICCAS), and an open response survey question on future intended practice. A total of 237 students participated in the simulation experience. Overall scores and scores on all IPCP competencies in the ICASS (n = 193) and SPICE-R (n = 226) improved for all professions post-simulation. The mean score of the ICCAS increased for 98% of the respondents and similarly the mean score of the SPICE-R increased for 71% of the respondents. Open-ended responses indicated students' intentions to pursue self-leadership in IPCP. Students who participated in an interprofessional simulation reported perceived improvements in IPCP competencies and were encouraged to initiate IPCP when on placement in the practice setting.

Molecular Mechanism for the Control of Eukaryotic Elongation Factor 2 Kinase by pH: Role in Cancer Cell Survival.

Acidification of the extracellular and/or intracellular environment is involved in many aspects of cell physiology and pathology. Eukaryotic elongation factor 2 kinase (eEF2K) is a Ca(2+)/calmodulin-dependent kinase that regulates translation elongation by phosphorylating and inhibiting eEF2. Here we show that extracellular acidosis elicits activation of eEF2K in vivo, leading to enhanced phosphorylation of eEF2. We identify five histidine residues in eEF2K that are crucial for the activation of eEF2K during acidosis. Three of them (H80, H87, and H94) are in its calmodulin-binding site, and their protonation appears to enhance the ability of calmodulin to activate eEF2K. The other two histidines (H227 and H230) lie in the catalytic domain of eEF2K. We also identify His108 in calmodulin as essential for activation of eEF2K. Acidification of cancer cell microenvironments is a hallmark of malignant solid tumors. Knocking down eEF2K in cancer cells attenuated the decrease in global protein synthesis when cells were cultured at acidic pH. Importantly, activation of eEF2K is linked to cancer cell survival under acidic conditions. Inhibition of eEF2K promotes cancer cell death under acidosis.
