Association between rural exposure/experience and practice location 10 years postgraduation, stratified by specialty: evidence from a cohort study of graduates from nine Australian universities.

OBJECTIVE: This study aims to determine the associations between specialty type and practice location at postgraduate year 10 (PGY10), matched with PGY5 and PGY8 work locations, and earlier rural exposure/experience. DESIGN AND SETTING: A cohort study of medicine graduates from nine Australian universities. PARTICIPANTS: 1220 domestic medicine graduates from the class of 2011. OUTCOME MEASURES: Practice location recorded by the Australian Health Practitioner Regulation Agency in PGY10; matched graduate movement between PGYs 5, 8 and 10 as classified by the Modified Monash Model, stratified by specialty type (predominantly grouped as general practitioner (GP) or non-GP). RESULTS: At PGY10, two-thirds (820/1220) had achieved fellowship. GPs were 2.8 times more likely to be in non-metropolitan practice (28% vs 12%; 95% CI 2.0 to 4.0, p<0.001) than graduates with non-GP (all other) specialist qualifications. More than 70% (71.4%) of GPs who were in non-metropolitan practice in PGY5 remained there in both PGY8 and PGY10 versus 29.0% of non-GP specialists and 36.4% of non-fellowed graduates (p<0.001). The proportion of fellowed graduates observed in non-metropolitan practice was 14.9% at PGY5, 16.1% at PGY8 and 19.0% at PGY10, with this growth predominantly from non-GP specialists moving into non-metropolitan locations, following completion of metropolitan-based vocational training. CONCLUSIONS: There are strong differences in practice location patterns between specialty types, with few non-GP specialists remaining in non-metropolitan practice between PGY5 and PGY10. Our study reinforces the importance of rural training pathways to longer-term work location outcomes and the need to expand specialist vocational training which supports more rural training opportunities for trainees outside general practice.

Influence of rural clinical school experience and rural origin on practising in rural communities five and eight years after graduation.

OBJECTIVE: To examine associations between extended medical graduates' rural clinical school (RCS) experience and geographic origins with practising in rural communities five and eight years after graduation. DESIGN, PARTICIPANTS: Cohort study of 2011 domestic medical graduates from ten Australian medical schools with rural clinical or regional medical schools. MAIN OUTCOME MEASURES: Practice location types eight years after graduation (2019/2020) as recorded by the Australian Health Practitioner Regulation Agency, classified as rural or metropolitan according to the 2015 Modified Monash Model; changes in practice location type between postgraduate years 5 (2016/2017) and 8 (2019/2020). RESULTS: Data were available for 1321 graduates from ten universities; 696 were women (52.7%), 259 had rural backgrounds (19.6%), and 413 had extended RCS experience (31.3%). Eight years after graduation, rural origin graduates with extended RCS experience were more likely than metropolitan origin graduates without this experience to practise in regional (relative risk [RR], 3.6; 95% CI, 1.8-7.1) or rural communities (RR, 4.8; 95% CI, 3.1-7.5). Concordance of location type five and eight years after graduation was 92.6% for metropolitan practice (84 of 1136 graduates had moved to regional/rural practice, 7.4%), 26% for regional practice (56 of 95 had moved to metropolitan practice, 59%), and 73% for rural practice (20 of 100 had moved to metropolitan practice, 20%). Metropolitan origin graduates with extended RCS experience were more likely than those without it to remain in rural practice (RR, 2.0; 95% CI, 1.3-2.9) or to move to rural practice (RR, 1.9; 95% CI, 1.2-3.1). CONCLUSION: The distribution of graduates by practice location type was similar five and eight years after graduation. Recruitment to and retention in rural practice were higher among graduates with extended RCS experience. Our findings reinforce the importance of longitudinal rural and regional training pathways, and the role of RCSs, regional training hubs, and the rural generalist training program in coordinating these initiatives.

Immersive placement experiences promote rural intent in allied health students of urban and rural origin.

INTRODUCTION: Pre-vocational placement experiences are known to considerably influence the career preferences of health graduates and are a key factor in growing the rural allied health workforce. This paper explores the rural placement experiences and future work intentions of students who attended a placement with the University of Newcastle Department of Rural Health. METHODS: Part of a larger longitudinal mixed methods study of students' placement experiences and subsequent career choices, this study explored students' placement evaluations responses. Following each placement, students were invited to complete an online survey which asked about their placement experiences and future work intentions. Counts and proportion tests were performed for frequencies of quantitative variables. Wilcoxon signed rank tests were conducted on the paired pre- and post-rural intent scores to determine any perceived differences in intent before and after placement for students both with and without a rural background. Qualitative data from short answer questions were analyzed thematically guided by qualitative content analysis. Data were comparatively analyzed for students of a rural or urban background. RESULTS: Four hundred and forty end of placement surveys were completed by 275 students (response rate 69.8%). There was a positive shift in intention to work rurally for students of both rural and urban background post-placement, but this was only statistically significant in the group from an urban background (p≤0.001). From the qualitative analysis three themes emerged: immersed rural supported placement experience, immersed interaction in rural life with other students, and immersed interaction in the rural community. Students from both rural and urban backgrounds indicated similar benefits and challenges. CONCLUSION: While the positive impact of rural placement experiences and rural background on future rural practice is well known, this study highlights the importance of positive supported placement experience for students from both rural and urban backgrounds.

Ideal Cricoid Pressure Is Biomechanically Impossible During Laryngoscopy.

OBJECTIVE: This study was a prospective, randomized controlled trial of rapid sequence intubation (RSI) with cricoid pressure (CP) within the emergency department (ED). The primary aim of the study was to examine the link between ideal CP and the incidence of aspiration. METHOD: Patients > 18 years of age undergoing RSI in the ED of two hospitals in New South Wales, Australia, were randomly assigned to receive measured CP using weighing scales to target the ideal CP range (3.060-4.075 kg) or control CP where the weighing scales were used, but the CP operator was blinded to the amount of CP applied during the RSI. A data logger recorded all CP delivered during each RSI. Immediately after intubation, tracheal and esophageal samples were taken and underwent pepsin analysis. RESULTS: Fifty-four RSIs were analyzed (25 measured/29 control). Macroscopic contamination of the larynx at RSI was observed in 14 patients (26%). During induction (0-50 seconds), both groups delivered in-range CP. During intubation (51-223 seconds), laryngoscopy was associated with a reduction in mean CP below 3.060 kg in both groups. When compared, there was no statistically significant difference between the groups. For 11 patients, pepsin was detected in the oropharyngeal sample, while three were positive for tracheal pepsin. Seven patients (four control/three measured) were treated for clinical aspiration during hospitalization. As a result of the finding that neither group could maintain ideal range CP during laryngoscopy, the trial was abandoned. CONCLUSION: Laryngoscopy provides a counter force to CP, which is negated to facilitate tracheal intubation. The concept that a static 3.060 to 4.075 kg CP could be maintained during laryngoscopy and intubation was rejected by our study. Whether a lower CP range could prevent aspiration during RSI was not explored by this study.

Longitudinal Tracking of Workplace Outcomes for Undergraduate Allied Health Students Undertaking Placements in Rural Australia.

Creating positive experiences in rural practice at the undergraduate level can influence allied health students' attitudes to working rurally. This study aimed to evaluate allied health students' experiences of their short-term, medium-term, or long-term rural placement and to follow their career outcomes. METHODS: The study used a mixed-methods design that utilised qualitative and quantitative data. Students from six allied health degree programs undertaking placements in Tamworth and Taree were invited to participate. Participation comprised of a series of surveys and an individual in-depth semi-structured interview. RESULTS: 198 students completed 257 end-of-placement surveys as of June 2014, with 72.7% reporting an intention to work rurally after placement. Fifty-five percent (n=51) of the 92 students who had never lived in a rural area had a more favourable attitude towards working rurally following placement. After 1 year, 50% of graduates were working in a rural or remote location, compared to 23.7% of all graduates from these disciplines. CONCLUSIONS: Preliminary findings indicated a positive perception of the rural placement experience and impact on intention to work rurally or in a rural location, particularly from those who had not previously spent time in a rural area. Future directions are to investigate longer-term workforce outcomes and the impact on the rural health workforce.

Post-traumatic stress disorder symptoms in pregnant Australian Indigenous women residing in rural and remote New South Wales: A cross-sectional descriptive study.

BACKGROUND: Pregnancy can be a stressful time for many women. There is ample evidence of numerous physical and mental health inequities for Indigenous Australians. For those Indigenous women who are pregnant, it is established that there is a higher incidence of poor physical perinatal outcomes when compared with non-Indigenous Australians. However, little evidence exists that examines stressful events and post-traumatic stress disorder (PTSD) symptoms in pregnant women who are members of this community. AIMS: To quantify the rates of stressful events and PTSD symptoms in pregnant Indigenous women. METHODS: One hundred and fifty rural and remote Indigenous women were invited to complete a survey during each trimester of their pregnancy. The survey measures were the stressful life events and the Impact of Events Scale. RESULTS: Extremely high rates of PTSD symptoms were reported by participants. Approximately 40% of this group exhibited PTSD symptoms during their pregnancy with mean score 33.38 (SD = 14.37) significantly higher than a study of European victims of crisis, including terrorism attacks (20.6, SD = 18.5). CONCLUSIONS: The extreme levels of PTSD symptoms found in the women participating in this study are likely to result in negative implications for both mother and infant. An urgent response must be mounted at government, health, community development and research levels to address these findings. Immediate attention needs to focus on the development of interventions to address the high levels of PTSD symptoms that pregnant Australian Indigenous women experience.

Evaluating interprofessional learning modules: health students' attitudes to interprofessional practice.

Interprofessional learning opportunities are thought to assist health students to work in a more collaborative, patient focussed manner during their career. In line with this thinking, the University of Newcastle's Department of Rural Health delivers monthly interprofessional learning modules (ILMs) to students on a range of health topics. Students' attitudes towards interprofessional learning were assessed pre- and post-ILM, using the Readiness for Interprofessional Learning scale (RIPLS). Thirty-eight students completed both pre- and post-surveys with a return rate of 36%. Our results demonstrated a statistically significant improvement in students' attitudes to interprofessional learning in three of four domains. Based on the findings from this study, ILMs appear to be a worthwhile educational opportunity and may improve student attitudes to interprofessional learning in the short term.

Effectiveness of cricoid pressure in preventing gastric aspiration during rapid sequence intubation in the emergency department: study protocol for a randomised controlled trial.

BACKGROUND: Cricoid pressure is considered to be the gold standard means of preventing aspiration of gastric content during Rapid Sequence Intubation (RSI). Its effectiveness has only been demonstrated in cadaveric studies and case reports. No randomised controlled trials comparing the incidence of gastric aspiration following emergent RSI, with or without cricoid pressure, have been performed. If improperly applied, cricoid pressure increases risk to the patient. The clinical significance of aspiration in the emergency department is unknown. This randomised controlled trial aims to; 1. Compare the application of the 'ideal" amount of force (30 - 40 newtons) to standard, unmeasured cricoid pressure and 2. Determine the incidence of clinically defined aspiration syndromes following RSI using a fibrinogen degradation assay previously described. METHODS/DESIGN: 212 patients requiring emergency intubation will be randomly allocated to either control (unmeasured cricoid pressure) or intervention groups (30 - 40 newtons cricoid pressure). The primary outcome is the rate of aspiration of gastric contents (determined by pepsin detection in the oropharyngeal/tracheal aspirates or treatment for aspiration pneumonitis up to 28 days post-intubation). Secondary outcomes are; correlation between aspiration and lowest pre-intubation Glasgow Coma Score, the relationship between detection of pepsin in trachea and development of aspiration syndromes, complications associated with intubation and grade of the view on direct largyngoscopy. DISCUSSION: The benefits and risks of cricoid pressure application will be scrutinised by comparison of the incidence of aspiration and difficult or failed intubations in each group. The role of cricoid pressure in RSI in the emergency department and the use of a pepsin detection as a predictor of clinical aspiration will be evaluated.

Phosphorylation of cold shock domain/Y-box proteins by ERK2 and GSK3beta and repression of the human VEGF promoter.

The hypoxia responsive region (HRR) of the VEGF promoter plays a key role in regulating VEGF expression. We found that the cold shock domain (Y-box) repressor proteins, dbpA and dbpB/YB-1, bind distinct strands of the human VEGF HRR. We find both dbpA and dbpB are phosphorylated by ERK2 and GSK3beta in vitro, and the binding of dbpB to single-strand VEGF HRR DNA is regulated by this phosphorylation. These findings suggest the ERK/MAPK and PI3K pathways may regulate VEGF expression in part through regulating the action of these repressor proteins.

Rapid detection and simultaneous subtype differentiation of influenza A viruses by real time PCR.

A real time RT-PCR, using the LightCycler, was developed and compared with rapid antigen enzyme immunoassay (AgEIA) and enhanced virus culture for rapid detection of influenza A viruses in stored and prospectively collected respiratory specimens. Specific hybridization probes were used for simultaneous detection and differentiation between H1N1 and H3N2 subtypes. The sensitivity of the RT-PCR for influenza A H1N1 was 120 copies and H3N2 350 copies of in vitro transcribed RNA. A specimen was considered positive for influenza A when it was culture positive or at least two methods yielded a positive test result. Using these criteria, with stored samples, the RT-PCR sensitivity, specificity, positive and negative predictive values were 82.9, 95.5, 98.9 and 52.5%, respectively. In specimens collected prospectively the RT-PCR sensitivity, specificity, positive and negative predictive values were 100, 87.9, 82.8 and 100%, respectively. There was complete concordance with subtype differentiation by hybridization probe melting temperature analysis and haemagglutination inhibition assay.

A novel mechanism of repression of the vascular endothelial growth factor promoter, by single strand DNA binding cold shock domain (Y-box) proteins in normoxic fibroblasts.

Overexpression of vascular endothelial growth factor (VEGF) is implicated in a number of diseases. It is therefore critical that mechanisms exist to strictly regulate VEGF expression. A hypoxia-responsive (HR) region of the VEGF promoter which binds the HIF-1 transcription factor is a target for many signals that up-regulate VEGF transcription. Repressors targeting the HIF-1 transcription factor have been identified but no repressors directly binding the HR promoter region had been reported. We now report a novel mechanism of repression of the VEGF HR region involving DNA binding. We find that single strand DNA-specific cold shock domain (CSD or Y-box) proteins repress the HR region via a binding site downstream of the HIF-1 site. The repressor site is functional in unstimulated, normoxic fibroblasts and represents a novel means to prevent expression of VEGF in the absence of appropriate stimuli. We characterized complexes forming on the VEGF repressor site and identified a previously unreported nuclear CSD protein complex containing dbpA. Nuclear dbpA appears to bind as a dimer and we determined a means by which nuclear CSD proteins may enter double strand DNA to bind to their single strand sites to bring about repression of the VEGF HR region.

Detection and subtyping of Herpes simplex virus in clinical samples by LightCycler PCR, enzyme immunoassay and cell culture.

BACKGROUND: Prompt laboratory diagnosis of Herpes simplex virus (HSV) infection facilitates patient management and possible initiation of antiviral therapy. In our laboratory, which receives various specimen types for detection of HSV, we use enzyme immunoassay (EIA) for rapid detection and culture of this virus. The culture of HSV has traditionally been accepted as the diagnostic 'gold standard'. In this study, we compared the use of real time PCR (LightCycler) for amplification, detection and subtyping of specific DNA with our in-house developed rapid and culture tests for HSV. RESULTS: The LightCycler PCR (LC-PCR) detected and subtyped HSV in 99% (66/67) of HSV positive specimens, compared to 81% (54/67) by rapid antigen EIA or 57% (36/63) by culture. A specimen was considered positive when two or more tests yielded HSV identifications or was culture positive. Discordant results were confirmed with an in-house developed PCR-ELISA or DNA sequence analysis. The typing results obtained with the LC-PCR and by culture amplified test were completely concordant. CONCLUSIONS: This study showed that the LC-PCR provided a highly sensitive test for simultaneous detection and subtyping of HSV in a single reaction tube. In addition to increased sensitivity, the LightCycler PCR provided reduced turn-around-times (2 hours) when compared to enzyme immunoassay (4 hours) or culture (4 days).
