RESUMO
BACKGROUND: Persistent pain is a highly prevalent, global cause of disability. Research suggests that many healthcare professionals are not well equipped to manage pain, and this may be attributable at least in part to undergraduate education. The primary aim of this study was to quantify and compare first and final year nursing, midwifery and allied health professional (NMAHP) students' pain related knowledge and attitudes. The secondary aim was to explore what factors influence students' pain related knowledge and attitudes. METHODS: In this cross-sectional study, 1154 first and final year healthcare students, from 12 universities in five different countries completed the Revised Neurophysiology of Pain Quiz (RNPQ) [knowledge] and the Health Care Providers Pain and Impairment Relationship Scale (HC-PAIRS) [attitudes]. RESULTS: Physiotherapy was the only student group with statistically and clinically improved pain related knowledge [mean difference, 95% CI] (3.4, 3.0 to 3.9, p = 0.01) and attitudes (-17.2, -19.2 to 15.2, p = 0.01) between first and final year. Pain education teaching varied considerably from course to course (0 to 40 h), with greater levels of pain related knowledge and attitudes associated with higher volumes of pain specific teaching. CONCLUSIONS: There was little difference in pain knowledge and attitudes between all first and final year NMAHP students other than physiotherapy. This suggests that for most NMAHP disciplines, undergraduate teaching has little or no impact on students' understanding of pain. There is an urgent need to enhance pain education provision at the undergraduate level in NMAHPs. TRIAL REGISTRATION: The study protocol was prospectively registered at ClinicalTrials.Gov NCT03522857 .

AIMS: Optimal urethrovesical positioning (UVP) may be important for continence. Pelvic floor muscle contraction (PFMC) influences UVP. PFMC instruction cues vary and often encourage anterior PFM recruitment that may result in sub-maximal posterior facilitation. STUDY HYPOTHESIS: posterior or combined cues are more influential in optimizing UVP during PFMC following a brief practice period than anterior cue. METHODS: Seventeen pre-menopausal, nulliparous, continent women were taught selective PFMC using different cues: anterior; posterior; anterior and posterior combined. Perineal ultrasound images of three PFMC for each cue were captured in supine and standing twice, 5 min apart. For reliability two raters measured data using angle of urethral inclination (AUI). Data analysis was undertaken using a customized General Linear Model ANOVA testing for interactions between all variables; subject, cue, posture, and test. Post hoc Bonferroni correction was used with a significance level of 0.05. RESULTS: The ANOVA showed significant differences between variables (P = 0.000). Post hoc analysis indicated significant differences between posterior and anterior cues 4.240° (P = 0.003); combined and anterior 3.756° (P = 0.009) but not between posterior and combined cues -0.484° (P = 1.00). Mean difference in AUI between supine and standing was 9.496° (P = 0.000); however, the interaction of cues and postures was not significant. CONCLUSIONS: AUI was significantly more acute/optimal when PFMC instruction included a posterior cue. This may be due to optimal recruitment of puborectalis and other posterior regional muscles which may be sub-maximally recruited with anterior cue. Investigation of the potential impact of these findings and possible usefulness of standardized instructions in PFM training is required.

We prepare a biotinylated conjugate of the ubiquitous plant hormone (S)-(+)-abscisic acid via an acyl hydrazone linkage at the C4' position and demonstrate in vivo cleavage of the otherwise stable acyl hydrazone linkage using LC-MS2. As part of a wider chemical genomic study, biological activity of the conjugate was assessed using standard epidermal peel and gravimetric transpiration assays, showing significant activity but at a level lower than the unconjugated hormone. When deuterated samples of the conjugate were fed to the plant, however, it was apparent by LC-MS2 experiments that significant levels of hydrolysis of the acyl hydrazone had taken place, contrary to in vitro stability assays in artificial sap. We conclude that abscisic acid is liberated in sufficient quantities to account for the observed physiological response and that LC-MS2 monitoring of conjugates is a simple and practical method by which such events may be assessed, whether in plants or other organisms.
