    Background: Whereas experience and cognitive maturity drives moral judgement development in most young adults, medical students show slowing, regression, or segmentation in moral development during their clinical years of training. The aim of this study was to explore the moral development of medical students during clinical training. Methods: A cross-sectional sample of medical students from three clinical years of training were interviewed in groups or individually at an Australian medical school in 2018. Thematic analysis identified three themes which were then mapped against the stages and dimensions of Self-authorship Theory. Results: Thirty five medical students from years 3–5 participated in 11 interviews and 6 focus groups. Students shared the impacts of their clinical experiences as they identified with their seniors and increasingly understood the clinical context. Their accounts revealed themes of early confusion followed by defensiveness characterised by desensitization and justification. As students approached graduation, some were planning how they would make moral choices in their future practice. These themes were mapped to the stages of self-authorship: External Formulas, Crossroads and Self-authorship. Conclusions: Medical students recognise, reconcile and understand moral decisions within clinical settings to successfully reach or approach self-authorship. Curriculum and support during clinical training should match and support this progress

    Background: Medical curricula are constantly evolving in response to the needs of society, accrediting bodies and developments in education and technology. The integration of blended learning modalities has challenged traditional methods of teaching, offering new prospects in the delivery of medical education. The purpose of this review is to explore how medical students adapt their learning behaviours in a Blended Learning environment to become more independent and self-regulated, in addition to highlighting potential avenues to enhance the curriculum and support student learning. Methods: Using the approach described by Levac et al. (2010), which builds on Arksey and O’Malley’s framework, we conducted a literature search of the following databases: MEDLINE (Ovid), ERIC, EBSCO, SCOPUS and Google Scholar, utilising key terms and variants of “medical student’, ‘self-regulated learning’ and ‘blended learning’. The search yielded 305 studies which were further charted and screened according to the Joanna Briggs Institute. Results: Forty-four studies were identified and selected for inclusion in this review. After full analysis of these studies, underpinned by Self-regulation theory, five major concepts associated with students’ learning behaviours in a Blended Learning environment were identified: Scaffolding of instructional guidance may support self-regulated learning; Self-regulated learning enhances academic performance; Self-regulated Learning improves study habits through resource selection; Blended learning drives student motivation and autonomy; and the Cognitive apprenticeship approach supports Self-regulated learning. Conclusion: This review uncovers medical students’ learning behaviours within a Blended learning environment which is important to consider for curricular adaptations and student support

    Background The gastrointestinal microbiota has an important role in mucosal immune homoeostasis and may contribute to maintaining mucosal healing in Crohn's disease (CD). Aim To identify changes in the microbiota, metabolome and protease activity associated with mucosal healing in established paediatric CD. Methods Twenty‐five participants aged 3‐18 years with CD, disease duration of over 6 months, and maintenance treatment with biological therapy were recruited. They were divided into a low calprotectin group (faecal calprotectin 100 ÎŒg/g, “mucosal inflammation,” n = 11). 16S gene‐based metataxonomics, 1H‐NMR spectroscopy‐based metabolic profiling and protease activity assays were performed on stool samples. Results Relative abundance of Dialister species was six times greater in the low calprotectin group (q = 0.00999). Alpha and beta diversity, total protease activity and inferred metagenomic profiles did not differ between groups. Pentanoate (valerate) and lysine were principal discriminators in a machine‐learning model which differentiated high and low calprotectin samples using NMR spectra (R2 0.87, Q2 0.41). Mean relative concentration of pentanoate was 1.35‐times greater in the low calprotectin group (95% CI 1.03‐1.68, P = 0.036) and was positively correlated with Dialister. Mean relative concentration of lysine was 1.54‐times greater in the high calprotectin group (95% CI 1.05‐2.03, P = 0.028). Conclusions This multiomic study identified an increase in Dialister species and pentanoate, and a decrease in lysine, in patients with “mucosal healing.” It supports further investigation of these as potential novel therapeutic targets in CD

    Intestinal goblet cells sample and deliver lumenal antigens by regulated endocytic uptake and transcytosis

    Intestinal goblet cells maintain the protective epithelial barrier through mucus secretion and yet sample lumenal substances for immune processing through formation of goblet cell associated antigen passages (GAPs). The cellular biology of GAPs and how these divergent processes are balanced and regulated by goblet cells remains unknown. Using high-resolution light and electron microscopy, we found that in mice, GAPs were formed by an acetylcholine (ACh)-dependent endocytic event remarkable for delivery of fluid-phase cargo retrograde into the trans-golgi network and across the cell by transcytosis - in addition to the expected transport of fluid-phase cargo by endosomes to multi-vesicular bodies and lysosomes. While ACh also induced goblet cells to secrete mucins, ACh-induced GAP formation and mucin secretion were functionally independent and mediated by different receptors and signaling pathways, enabling goblet cells to differentially regulate these processes to accommodate the dynamically changing demands of the mucosal environment for barrier maintenance and sampling of lumenal substances

    ALIA Darling Downs is a regional professional community in its infancy. It exists to provide a platform for library practitioners in the regional Darling Downs area to network with other library professionals, stay up-to-date with library practices and attend professional development events. This group has members from a wide geographically dispersed area where the librarians are usually the only information professionals in their local communities. Our focus is to facilitate discussions and build our community. We aim to ensure the continuing involvement of Darling Downs library staff in matters pertaining to the profession. One of the biggest issues impacting the industry at the moment is COVID-19

    A review of reporting of participant recruitment and retention in RCTs in six major journals

    <p>Abstract</p> <p>Background</p> <p>Poor recruitment and retention of participants in randomised controlled trials (RCTs) is problematic but common. Clear and detailed reporting of participant flow is essential to assess the generalisability and comparability of RCTs. Despite improved reporting since the implementation of the CONSORT statement, important problems remain. This paper aims: (i) to update and extend previous reviews evaluating reporting of participant recruitment and retention in RCTs; (ii) to quantify the level of participation throughout RCTs.</p> <p>Methods</p> <p>We reviewed all reports of RCTs of health care interventions and/or processes with individual randomisation, published July–December 2004 in six major journals. Short, secondary or interim reports, and Phase I/II trials were excluded. Data recorded were: general RCT details; inclusion of flow diagram; participant flow throughout trial; reasons for non-participation/withdrawal; target sample sizes.</p> <p>Results</p> <p>133 reports were reviewed. Overall, 79% included a flow diagram, but over a third were incomplete. The majority reported the flow of participants at each stage of the trial after randomisation. However, 40% failed to report the numbers assessed for eligibility. Percentages of participants retained at each stage were high: for example, 90% of eligible individuals were randomised, and 93% of those randomised were outcome assessed. On average, trials met their sample size targets. However, there were some substantial shortfalls: for example 21% of trials reporting a sample size calculation failed to achieve adequate numbers at randomisation, and 48% at outcome assessment. Reporting of losses to follow up was variable and difficult to interpret.</p> <p>Conclusion</p> <p>The majority of RCTs reported the flow of participants well after randomisation, although only two-thirds included a complete flow chart and there was great variability over the definition of "lost to follow up". Reporting of participant eligibility was poor, making assessments of recruitment practice and external validity difficult. Reporting of participant flow throughout RCTs could be improved by small changes to the CONSORT chart.</p

    Background &amp; Aims: Novel finite therapies for chronic hepatitis B (CHB) are needed, since lifelong treatment is usually required with current available oral antivirals. This phase II study (NCT03615066) evaluated the safety, pharmacodynamics, and antiviral activity of selgantolimod (a Toll-like receptor 8 agonist [TLR8]) with tenofovir alafenamide (TAF). Methods: Viremic patients with CHB not receiving treatment were stratified by HBeAg status and randomized 2:2:1 to TAF 25 mg/day with selgantolimod 3 mg orally once weekly (QW), selgantolimod 1.5 mg QW, or placebo. Combination therapy continued until week (W)24, followed by TAF monotherapy until W48; patients then discontinued TAF and were followed until W96 (treatment-free follow-up [TFFU] period). The primary efficacy endpoint was the proportion with ≄1 log10 IU/ml HBsAg decline at W24. Results: Sixty-seven patients received study drug; 27 were followed during TFFU. Nausea, headache, vomiting, fatigue, and dizziness were the most common adverse events. Most adverse events were grade 1. Alanine aminotransferase flares were not observed up to W48. Four patients experienced alanine aminotransferase and hepatitis flares during TFFU; all had HBV DNA increases. Selgantolimod increased serum cytokines and chemokines and redistributed several circulating immune cell subsets. No patients achieved the primary efficacy endpoint. Mean HBsAg changes were −0.12, −0.16, and −0.12 log10 IU/ml in the selgantolimod 3 mg, selgantolimod 1.5 mg, and placebo groups, respectively, at W48; HBV DNA declined in all groups by ≄2 log10 IU/ml as early as W2, with all groups rebounding to baseline during TFFU. No HBsAg or HBeAg loss or seroconversion was observed throughout TFFU. Conclusions: Selgantolimod up to 3 mg was safe and well tolerated. Pharmacodynamics and antiviral activity in viremic patients support continued study of selgantolimod in combination CHB therapies. Impact and implications: Novel therapeutics for chronic HBV infection are needed to achieve a functional cure. In this study, we confirmed the safety and tolerability of selgantolimod (formerly GS-9688, a TLR8) when administered with tenofovir alafenamide over 24 weeks in viremic patients with chronic HBV infection. Overall, declines in HBsAg levels with selgantolimod treatment were modest; subgroup analysis indicated that patients with alanine aminotransferase levels greater than the upper limit of normal had significantly greater declines compared to those with normal alanine aminotransferase levels (–0.20 vs. –0.03 log10 IU/ml; p &lt;0.001). These findings suggest a potential differential response to selgantolimod based on patients’ baseline HBV-specific immune response, which should be considered in future investigations characterizing the underlying mechanisms of selgantolimod treatment and in HBV cure studies using similar immunomodulatory pathways. Clinical trial number: NCT03615066 be found at https://www.gileadclinicaltrials.com/transparency-policy/.</p
