Abstract: Omega-3 polyunsaturated fatty acids (n-3 PUFA) are termed essential fatty acids because they cannot be synthesized de novo by humans due to the lack of delta-12 and delta-15 desaturase enzymes and must therefore be acquired from the diet. n-3 PUFA include α-linolenic acid (ALA, 18:3n-3), eicosapentaenoic (EPA, 20:5n-3), docosahexaenoic (DHA, 22:6n-3), and the less recognized docosapentaenoic acid (DPA, 22:5n-3). The three long-chain (≥C20) n-3 PUFA (n-3 LC-PUFA), EPA, DHA, and DPA play an important role in human health by reducing the risk of chronic diseases. Up to the present time, seafood, and in particular, fish oil-derived products, have been the richest sources of n-3 LC-PUFA. The human diet generally contains insufficient amounts of these essential FA due largely to the low consumption of seafood. This issue provides opportunities to enrich the content of n-3 PUFA in other common food groups. Milk and milk products have traditionally been a major component of human diets, but are also among some of the poorest sources of n-3 PUFA. Consideration of the high consumption of milk and its processed products worldwide and the human health benefits has led to a large number of studies targeting the enhancement of n-3 PUFA content in dairy products. The main objective of this review was to evaluate the major strategies that have been employed to enhance n-3 PUFA content in dairy products and to unravel potential knowledge gaps for further research on this topic. Nutritional manipulation to date has been the main approach for altering milk fatty acids (FA) in ruminants. However, the main challenge is ruminal biohydrogenation in which dietary PUFA are hydrogenated into monounsaturated FA and/or ultimately, saturated FA, due to rumen microbial activities. The inclusion of oil seed and vegetable oil in dairy animal diets significantly elevates ALA content, while the addition of rumen-protected marine-derived supplements is the most effective way to increase the concentration of EPA, DHA, and DPA in dairy products. In our view, the mechanisms of n-3 LC-PUFA biosynthesis pathway from ALA and the biohydrogenation of in idual n-3 LC-PUFA in ruminants need to be better elucidated. Identified knowledge gaps regarding the activities of candidate genes regulating the concentrations of n-3 PUFA and the responses of ruminants to specific lipid supplementation regimes are also critical to a greater understanding of nutrition-genetics interactions driving lipid metabolism.

Abstract: The aim of this study was to determine the effects of pasture (cocksfoot cv. porto (CFP) and lucerne) and supplementation of grazing lambs with pellets with or without plant oil infusion on performance and carcass characteristics. Forty-eight White Suffolk x Corriedale first-cross weaners were randomly assigned to one of four treatments in a split-plot experimental design: (1) CFP or lucerne pastures only (control) CFP or lucerne pastures supplemented with pellets infused with oil from (2) canola (CO) (3) rice bran (RBO) and (4) no oil pellets (NOP). Lucerne and CFP pastures were considered as the main plot effect, and played the role of basal pastures. Lambs grazing lucerne or CFP pastures with pellet supplementation achieved carcass weights of kg at 9 weeks, which met the specific requirements of Asian and United States of America export markets. Pellet supplementation did not affect final liveweight, average daily gain, body length, withers height and chest girth of grazing lambs. Dressing percentage of lambs grazing CFP pasture with pellet supplementation and lambs grazing lucerne pasture with RBO supplementation increased compared with lambs on pasture grazing only. Although supplementing lambs on CFP pasture with CO had relatively negligible impact on feed conversion efficiency, it significantly increased over the hook trade value compared with lambs grazing CFP pasture only. In conclusion, lucerne or CFP pasture plus pellet supplementation produced lamb carcasses kg suitable for the export market. CO had relatively low feed cost per unit daily gain (0.9 $AU/kg on CFP pasture and 0.6 $AU/kg on lucerne pasture) and could also be used as a tactical supplementation tool for increasing the carcass weight of lambs grazing CFP pasture.

Abstract: This article was migrated. The article was marked as recommended. Method:This study utilized a mixed-method design involving a cross-sectional survey (n=111, response rate=61%) to compare Year 2 medical student perceptions of content delivered by a Blended Integrated Learning (BIL) approach versus a traditional didactic teaching (TT) approach, plus 2 focus groups to explore learner perceptions of the BIL approach and brainstorm improvements. Results: Most medical students preferred the BIL approach over TT with respect to 'practically applying basic sciences to a patient case' and 'knowledge retention in the subject' (53% versus 30%, and 51% versus 35%, respectively). However, most medical students preferred TT with respect to 'level of interaction with other students and lecturers while reviewing teaching materials' (78% versus 11%), 'overall enjoyment of learning' (54% versus 32%), and 'understanding the lecture content faster' (49% versus 39%). Focus groups identified what did and did not work with the BIL approach and brain-stormed specific improvement strategies. Conclusions : Students preferred BIL over TT for knowledge retention and integrating basic sciences into common clinical cases, but found BIL less preferable for aspects related to learning engagement. However, focus groups identified a variety of strategies to promote student engagement in BIL by improving online content, delivery processes and further innovative use of technology.

Abstract: The hypothesis tested was that tropical steers supplemented with the Desmanthus legume and lucerne, a widely characterized temperate legume of high nutritive value, would elicit similar responses in plasma metabolite profiles, productive performance, nitrogen retention, and volatile fatty acids (VFA). The tannin-binding compound, polyethylene glycol-4000 (PEG), was added to the diets (160 g/kg Desmanthus dry matter) with the objective of further exploring nitrogen (N) utilization in the animals supplemented with Desmanthus relative to lucerne. From February to June 2020, sixteen yearling Brangus steers (average liveweight of 232 ± 6 kg) were fed a background diet of Rhodes grass (Chloris gayana) hay for 28 days, before introducing three Desmanthus cultivars (Desmanthus virgatus cv. JCU2, D. bicornutus cv. JCU4, D. leptophyllus cv. JCU7) and lucerne (Medicago sativa) at 30% dry matter intake (DMI). Relative to the backgrounding period, all supplemented steers exhibited similar growth performance. Steers supplemented with Desmanthus recorded a lower DMI and animal growth performance, but higher fecal N concentration than animals supplemented with lucerne. Among the three Desmanthus cultivars, there were no significant differences in N concentrations, VFA, and plasma metabolite profiles. The addition of PEG induced higher rumen iso-acid concentrations and fecal N excretion. However, feeding Desmanthus spp. to tropical Bos indicus steers could be a valuable means of increasing N utilization, which is attributable to the presence of tannins, and, consequently, improve animal productive performance. Since supplementation with lucerne resulted in higher liveweight, daily liveweight gains, and overall animal performance than supplementing with Desmanthus, the tested hypothesis that both supplements will elicit similar animal performance does not hold and must be rejected. Further in vivo investigation is needed to better understand the impact of tannins in Desmanthus on N utilization.

Abstract: The aim of this study was to evaluate the preliminary efficacy and user acceptance of My Care Hub (MCH) mobile app—developed to provide evidenced-based support and education on diabetes self-management (DSM). Using a mixed-methods design, the efficacy and acceptability of MCH were measured among people with type 1 or type 2 diabetes after three weeks of intervention. The primary outcome measure was level of involvement with DSM, while the mediating factors were skills and self-efficacy for DSM. Telephone interviews were conducted to elucidate information on perceptions of the app’s impact on participants’ DSM and interest in future use. Statistically significant improvements were observed between pre- and post-intervention measures: DSM activities (4.55 ± 1.14 vs. 5.35 ± 0.84 p = 0.001) skills (7.10 ± 1.99 vs. 7.90 ± 1.67 p = 0.04) and self-efficacy (7.33 ±1.83 vs. 8.07 ± 1.54 p = 0.03). Multivariate analysis showed that self-efficacy had the strongest, though not significant influence on DSM. Interview findings revealed that the app reinforced knowledge and provided motivation to participate in DSM activities. The study suggested a positive impact of MCH on DSM and acceptability by patients. To confirm these promising results, further large scale and long-term studies are required.

Abstract: Non-adherence to self-management poses a serious risk to diabetes complications. Digital behavioural change interventions have the potential to provide education and motivate users to regularly engage with self-management of diabetes. This paper describes the development of My Care Hub mobile phone application (app) aimed at supporting self-management in people with type 1 or type 2 diabetes. The development of My Care Hub involved a comprehensive process of healthy behavioural change identification, end users’ needs, expert consensus, data security and privacy considerations. The app translation was a highly iterative process accompanied by usability testing and design modification. The app development process included: (1) behaviour change strategy selection (2) users’ involvement (3) expert advisory involvement (4) data security and privacy considerations (5) design creation and output translation into a smartphone app and (6) two usability testings of the app prototype version. The app features include self-management activities documentation, analytics, personalized and generalized messages for diabetes self-management as well as carbohydrate components of common foods in Australia. Twelve respondents provided feedback on the usability of the app. Initially, a simplification of the documentation features of the app was identified as a need to improve usability. Overall, results indicated good user satisfaction rate.

Abstract: The transition from pre-clinical to clinical medical training is often characterised by several challenges which may have different impacts on students’ well-being and learning experiences. To ensure smooth transition, it’s important to understand how these students navigate through the challenging processes. This study employed a mixed-methods design using a survey, focus groups and interviews among medical students who had entered their first clinical year of study (Year 4). Using a 5-point Likert scale, survey participants rated items which related to their transition experience in the areas of professional socialisation workload patient contact knowledge and skills and learning and education. The qualitative questions explored challenges in transition, coping strategies and recommendations to foster smooth transitioning. The survey data was analysed using descriptive and inferential statistics while thematic analysis was used to establish emerging themes from the qualitative data. The Westerman Transition Framework was utilised in the triangulation of study findings. A total of 141 students participated in the survey while 12 students participated in the focus group discussions and interviews. The quantitative part of the study showed that the students were anxious about the process and considered the workload to be heavy while also identifying gaps in their knowledge. Similarly, the qualitative findings revealed that workload and professional socialisation were identified as disruptive novel elements and the students also reported feelings of inadequacy and incompetence due to perceived knowledge gaps. These shortcomings and challenges were tackled by seeking support from peers and senior medical students as a way of coping with the anxiety and stress. As the students progressed, they admitted and accepted that the transition was a gradual process and an essential learning curve. The process of transitioning from preclinical to clinical years is considered stressful and abrupt with the introduction of disruptive novel elements that create feelings of incompetence and unpreparedness in students. Educators need to consider developing social and developmental strategies that emphasise nurturing and empowering clinical learning environments and facilitate reflective and transformative life-long learning opportunities for students.

Abstract: Efforts to control the COVID-19 pandemic have expanded to the vaccination of children and adolescents. This systematic review assesses the utility of the BNT162b2 (Pfizer-BioNTech) vaccine in children and adolescents aged 5–18 years, considering its effectiveness against COVID infection, hospital and intensive care admission and duration of effectiveness after vaccination. Six databases were searched following the PRISMA guidelines. Pooled estimates and 95% confidence intervals (CIs) were calculated using meta-analysis. Fifteen studies were included in the systematic review, while 12 studies were included in the meta-analysis. Evidence suggests that the two-dose vaccination regime provided high effectiveness of 92% (95% CI, 86–96) against COVID infection. Vaccination also conferred high protection against hospitalisation (91%) and intensive care admission (85%). The vaccine was highly protective against the Delta variant of the virus, but showed a lower protection against the Omicron variant. Most adverse effects were transient and mild, commonly including pain at the injection site, fatigue and headache. Current findings are suggestive of waning immunity over time however, further research is needed to investigate the relevance of booster doses in this age group. In summary, the Pfizer-BioNTech BNT162b2 vaccine demonstrated high levels of protection against COVID-19 infection and its complications while maintaining an adequate safety profile in children and adolescents.

Abstract: The enhancement of health-beneficial omega-3 long–chain (≥C20) polyunsaturated fatty acid (n-3 LC-PUFA) contents in the muscle, liver, heart, and kidney of Australian prime lambs through pasture grazing and supplementation with oil infused pellets was investigated. Forty-eight first-cross prime lambs were randomly assigned into a split-plot design with pasture type as the main plot effect and pellet supplementation as a sub-plot effect in a feeding trial that lasted for nine weeks. The n-3 LC-PUFA content in Longissimus dorsi muscle of all lambs was well above the 30 mg threshold for “omega-3 source” nutrition claim under the Australian Food Standards and Guidelines. Pasture type impacted the fatty acid contents in muscle, heart, and kidney of prime lambs. Lambs grazing cocksfoot grass only had high 18:3n-3 (ALA) and n-3 LC-PUFA contents (67.1 mg/100 g and 55.2 mg/100 g, respectively) in the Longissimus dorsi muscle, which was not significantly different (p 0.8990) from the contents of lambs grazing only lucerne. Supplementation of pellets with or without oil infusion to grazing lambs generally decreased the ALA and n-3 LC-PUFA contents and increased the n-6/n-3 ratio in the Longissimus dorsi muscle. The fatty acid content in the internal organs of grazing lambs was also affected by pellet supplementation. The liver and kidney of grazing lambs were both “good sources” (60 mg/100 g) of omega-3. The cocksfoot grass showed considerable potential for producing healthy, premium quality meat with high contents of n-3 and n-3 LC-PUFA, which may consequently enhance the omega-3 intake of Australian lamb consumers.

Abstract: Teachers belong to a high-demand occupational group and experience work-related challenges and discretely erse emotional turmoils of varying intensity while teaching and interacting with students. These experiences often result in high stress levels that contribute to burnout and, consequently, a breach of teachers’ occupational wellbeing. Promoting positive teacher wellbeing substantially influences teaching quality, with a flow-on effect on student wellbeing and academic development. This literature review utilised a framework to systematically explore the factors that impact the occupational wellbeing of kindergarten, primary, and secondary schoolteachers. Thirty-eight (38) studies from an initial 3766 peer-reviewed articles sourced from various databases (CINAHL, Emcare, PychINFO, Scopus, ERIC, and PsycARTICLES) were utilized for this systematic review. Four major factors were identified, including personal capabilities, socioemotional competence, personal responses to work conditions, and professional relationships. Findings highlight the importance of teachers’ occupational wellbeing in dealing with numerous challenges and competing demands, with the need for a high level of self-efficacy for instruction and behavioural management being critically significant. Teachers require adequate organisational support to successfully carry out their roles with stronger resilience and efficient job execution. Teachers also need to have social–emotional competence to be able to create a high-quality classroom environment and a conducive atmosphere that supports healthy teacher–student relationships, reduces stress and increases the occupational wellbeing of teachers. Collaborating with other relevant stakeholders such as parents, colleagues, and a school’s leadership team is critical for creating a positive work environment. A good workplace has the potential to contribute to teachers’ occupational wellbeing and provide a supportive platform for student learning and engagement. This review clearly points to the beneficial effects of prioritising teachers’ occupational wellbeing and its intentional inclusion in the professional development plan of practising teachers. Finally, while primary school teachers and secondary school teachers share many similarities in terms of the challenges they face, there are also some differences in how these challenges impact their wellbeing, and these warrant further investigation.

Abstract: Heat tolerance and exertional heat stroke (EHS) are rare health conditions that have been described and characterised but have never been genetically solved. Knowledge of the role of single nucleotide polymorphisms (SNPs) in heat shock proteins (HSPs) genes and their associations with heat tolerance and EHS is limited. This pilot study aimed to identify SNP in HSPA1B, HSP90AA2 and DNAJA1 genes and their associations with heat tolerance and EHS history in a quasi-experimental design. Participants comprised Australian Defence Force members (ADF) who had a history of EHS and the general population. Genomic DNA s les were extracted from the venous blood s les of 48 participants, sequenced and analysed for SNP. Forty-four per cent (44%) of the participants were heat intolerant, and 29% had a history of EHS. Among participants with a history of EHS, there was an association between heat tolerance and HSPA1B SNP at the g.31829044 locus. However, there were no associations between HSPA1B and HSP90AA2 SNP and heat tolerance. All participants had the same distribution for the DNAJA1 SNP. In conclusion, the findings indicate an association between the HSPA1B genetic variant at the g.31829044 locus and heat tolerance among ADF participants with a history of EHS. Further research with a larger number of military participants will shed more light on the associations between HSP genes and heat tolerance.

Abstract: The government of Ghana has been piloting traditional medicine (TM) integration in 17 health facilities across the country. However, the nature of current practice of integrated healthcare has not been thoroughly explored. This paper sought to explore the experiences and recommendations of orthodox health practitioners and hospital administrators in the Ashanti region regarding the practice of integrated healthcare in Ghana. The study adopted a qualitative, phenomenological approach involving 22 interviews. Purposive s ling technique was used in selecting study participants. Framework analysis was used to draw on the experiences of participants relating to TM integration. Participants were knowledgeable about the existence of integrated health facilities and stated that TM integration has created options in health services. However, participants deemed the integrated system ineffective and attributed the inefficiency to poor processing and certification of TM products, opposition of medical doctors to TM usage, absence of a protocol to guide the integration process, and inadequate publicity. Professional training of TM practitioners and inclusion of TM in medical school curriculum could improve collaboration between the health practitioners. Future research should focus on assessing the opinions and involvements of TM practitioners regarding the integration of traditional therapies into national health systems.

Abstract: The objective of this study was to investigate the effects of enriched omega-3 oil supplemental pellets, breed and gender on lamb liveweight (LWT), body conformation and carcass characteristics, and to assess the relationships between body conformation and growth under an intensive finishing condition. Sixty ewe and wether prime lambs 7 months old were randomly allocated to one of five dietary treatments: no oil inclusion (Control) 2.5% canola oil 5% canola oil 2.5% flaxseed oil and 5% flaxseed oil, balanced by breed (purebred Merinos (M × M) and Corriedale × Merino (C × M) and White Suffolk × Corriedale (W × C) first crosses). Lambs were in idually supplemented with 1 kg pellets per day and had free access to lucerne hay and water throughout the 7-week feeding trial, after a 3-week adaptation. Dietary oil inclusion did not cause significant differences in daily feed intake, growth performance and carcass characteristics (P 0.05). However, first-cross W × C lambs had significantly higher feed intake, chest girth and body conformation score (P 0.05) than M × M and C × M lambs. Carcass weight, dressing percentage and fat depth of crossbred lambs were significantly higher than those of M × M (P 0.05). Significant interactions between oil inclusion and breed on average daily gain (ADG) and feed conversion ratio were observed. There were positive and highly significant correlations among LWT, ADG and body conformation measurements (P 0.01). These findings suggest that prime lamb producers can better manage and match their breeding goals with feed resources by supplementing first-cross C × M lambs with pellets containing 5% canola oil or feeding first-cross W × C lambs with 5% flaxseed oil pellets during the 10-week intensive finishing period.

Abstract: Background and objective: Traditional medicine (TM) was integrated into health systems in Africa due to its importance within the health delivery setup in fostering increased health care accessibility through safe practices. However, the quality of integrated health systems in Africa has not been assessed since its implementation. The objective of this paper was to extensively and systematically review the effectiveness of integrated health systems in Africa. Materials and Methods: A systematic literature search was conducted from October, 2019 to March, 2020 using Ovid Medline, Scopus, Emcare, Web of Science, Cumulative Index to Nursing and Allied Health (CINAHL), and Google Scholar, in order to retrieve original articles evaluating the integration of TM into health systems in Africa. A quality assessment of relevant articles was also carried out using the Quality Assessment Tool for Studies with Diverse Designs (QATDSS) critical appraisal tool. Results: The results indicated that the formulation and execution of health policies were the main measures taken to integrate TM into health systems in Africa. The review also highlighted relatively low levels of awareness, usage, satisfaction, and acceptance of integrated health systems among the populace. Knowledge about the existence of an integrated system varied among study participants, while satisfaction and acceptance were low among orthodox medicine practitioners. Health service users’ satisfaction and acceptance of the practice of an integrated health system were high in the countries assessed. Conclusion: The review concluded that existing health policies in Africa are not working, so the integration of TM has not been successful. It is critical to uncover the barriers in the health system by exploring the perceptions and experiences of stakeholders, in order to develop solutions for better integration of the two health systems.

Abstract: The Australian beef industry is a major contributor to the economy with an estimated annual revenue generation of over seven billion dollars. The tropical state of Queensland accounted for 48% of Australian beef and veal production in 2018. As the third biggest beef exporter in the world, Australia supplies 3% of the world’s beef exports and its agricultural sector accounts for an estimated 13.2% of its total greenhouse gas emissions. About 71% of total agricultural emissions are in the form of methane and nitrous oxide. In this review, an overview of the carbon footprint of the beef cattle production system in northern Australia is presented, with emphasis on the mitigation of greenhouse gases. The review also focuses on the tropical legume, Desmanthus, one of the more promising nutritional supplements for methane abatement and improvement of animal growth performance. Among the review’s findings is the need to select environmentally well-adapted and vigorous tropical legumes containing tannins that can persistently survive under the harsh northern Australian conditions for driving animal performance, improving meat quality and reducing methane emissions. The paper argues that the use of appropriate legumes such as Desmanthus, is a natural and preferred alternative to the use of chemicals for the abatement of methane emanating from tropical beef cattle production systems. It also highlights current gaps in knowledge and new research opportunities for in vivo studies on the impact of Desmanthus on methane emissions of supplemented tropical beef cattle.

Abstract: This study evaluated omega-3 intramuscular fatty acids in the longissimus thoracis et lumborum of commercially prepared Australian lamb loin chops. Meats, denuded of external fats were cooked by means of conductive dry-heat using a fry grilling hot plate, to a core temperature of 70°C. An untrained consumer panel assessed meat appearance, aroma, tenderness, juiciness, taste and overall liking. Results showed no compositional alterations (P>0.05) to omega-3 fatty acids due to cooking treatment, whereas on absolute terms (mg/100g muscle) omega-3 fatty acids significantly (P<0.05) increased. The mean EPA+DHA content of the cooked meat at 32.8±2.3mg/100g muscle exceeded the minimum 30mg/100g per edible portion required for the defined Australian classification as 'source' long-chain (≥C

Abstract: (1) Background: Globally, persons with disabilities (PWDs) face numerous challenges including access to healthcare. This scoping review sought to assess the level of inclusiveness in Ghanaian health policies and reports for PWDs (2) Methods: An extensive search and scoping review of health policies/reports in Ghanaian government websites and Google was conducted. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for scoping reviews were followed in selecting and reporting the policies/reports. The program evaluation and policy design framework was employed for content analysis (3) Results: Fifteen policies and reports with political recognition, objectives, and specific resources needed to execute stipulated plans were included. Although these policies and reports had collaborative partnerships with various institutions and organisations in development and implementation plans, the level of inclusiveness of disability issues was very low. Only eight out of the fifteen policies/reports (53%) reviewed considered PWDs, indicating a low level of inclusion. The definition of disability was also limited. (4) Conclusions: To achieve the sustainable development goal of ‘leaving no one behind’ in line with the provisions of the United Nations Convention on the Right of Persons with Disabilities and the Disability Act 715 of Ghana, it is recommended that subsequent health policies should have an in-depth engagement with PWDs from the conceptual design stage right through to implementation and evaluation.

Abstract: A comprehensive review of the impact of tropical pasture grazing, nutritional supplementation during feedlot finishing and fat metabolism-related genes on beef cattle performance and meat-eating traits is presented. Grazing beef cattle on low quality tropical forages with less than 5.6% crude protein, 10% soluble starches and 55% digestibility experience liveweight loss. However, backgrounding beef cattle on high quality leguminous forages and feedlot finishing on high-energy diets increase meat flavour, tenderness and juiciness due to improved intramuscular fat deposition and enhanced mono- and polyunsaturated fatty acids. This paper also reviews the roles of stearoyl-CoA desaturase, fatty acid binding protein 4 and fatty acid synthase genes and correlations with meat traits. The review argues that backgrounding of beef cattle on Desmanthus, an environmentally well-adapted and vigorous tropical legume that can persistently survive under harsh tropical and subtropical conditions, has the potential to improve animal performance. It also identifies existing knowledge gaps and research opportunities in nutrition-genetics interactions aimed at a greater understanding of grazing nutrition, feedlot finishing performance, and carcass traits of northern Australian tropical beef cattle to enable red meat industry players to work on marbling, juiciness, tenderness and overall meat-eating characteristics.

Abstract: The James Cook University General Practice Training (JCU GPT) programme’s internal formative exams were compared with the Royal Australian College of General Practitioners (RACGP) pre-entry exams to determine ability to predict final performance in the RACGP fellowship exams. A retrospective longitudinal study. General Practice (GP) trainees enrolled between 2016 and 2019 at a Registered Training Organisation in regional Queensland, Australia. 376 GP trainees enrolled in the training programme. The pre-entry exams were Multiple-Mini Interviews (MMI), Situational Judgement Test (SJT) and Candidate Assessment and Applied Knowledge Test. The internal formative exams comprised multiple choice questions (MCQ1 and MCQ2), short answer questions, clinical skills and clinical reasoning. The college exams were Applied Knowledge Test (AKT), Key Feature Problems (KFP) and Objective Structured Clinical Examination (OSCE). Correlations (r), coefficients of determination (R 2 ) and OR were used as parameters for estimating strength of relationship and precision of predictive accuracy. SJT and MMI were moderately (r=0.13 to 0.31) and MCQ1 and MCQ2 highly (r=0.37 to 0.53) correlated with all college exams (p .05 to p .01), with R 2 ranging from 0.070 to 0.376. MCQ1 was predictive of failure in all college exams (AKT: OR=2.32, KFP: OR=3.99 OSCE: OR=3.46) while MCQ2 predicted failure in AKT (OR=2.83) and KFP (OR=3.15). We conclude that the internal MCQ formative exams predict performance in the RACGP fellowship exams. We propose that our formative assessment tools could be used as academic markers for early identification of potentially struggling trainees.

Abstract: Desmanthus ( Desmanthus spp.), a tropically adapted pasture legume, is highly productive and has the potential to reduce methane emissions in beef cattle. However, liveweight gain response to desmanthus supplementation has been inconclusive in ruminants. This study aimed to evaluate weight gain, rumen fermentation and plasma metabolites of Australian tropical beef cattle in response to supplementation with incremental levels of desmanthus forage legume in isonitrogenous diets. Forty-eight Brahman, Charbray and Droughtmaster crossbred beef steers were pen-housed and fed a basal diet of Rhodes grass ( Chloris gayana ) hay supplemented with 0, 15, 30 or 45% freshly chopped desmanthus forage on dry matter basis, for 140 days. Varying levels of lucerne ( Medicago sativa ) hay were added in the 0, 15 and 30% diets to ensure that all diets were isonitrogenous with the 45% desmanthus diet. Data were analyzed using the Mixed Model procedures of SAS software. Results showed that the proportion of desmanthus in the diet had no significant effect on steer liveweight, rumen volatile fatty acids molar proportions and plasma metabolites ( P ≥ 0.067). Total bilirubin ranged between 3.0 and 3.6 μmol/L for all the diet treatments ( P = 0.67). All plasma metabolites measured were within the expected normal range reported for beef cattle. Rumen ammonia nitrogen content was above the 10 mg/dl threshold required to maintain effective rumen microbial activity and maximize voluntary feed intake in cattle fed low-quality tropical forages. The average daily weight gains averaged 0.5 to 0.6 kg/day ( P = 0.13) and were within the range required to meet the target slaughter weight for prime beef markets within 2.5 years of age. These results indicate that desmanthus alone or mixed with other high-quality legume forages can be used to supplement grass-based diets to improve tropical beef cattle production in northern Australia with no adverse effect on cattle health.

Abstract: Pre-existing acculturation models have focused on in idual orientation and may not be fully applicable to African migrants due to their strong connection to family. In this study, we utilised qualitative semi-structured interviews to explore how 22 migrant families from eight sub-Saharan African representative countries: Congo, Eritrea, Kenya, Nigeria, Rwanda, Sierra Leone, Uganda and Zimbabwe, who now reside in Townsville, Australia experienced the acculturation process. Data were analysed at the family unit level using the three steps of grounded theory method: open, axial and selective coding. The theory derived illustrates that the acculturation process involves two major phases (maintaining core moral values and attaining a sense of belonging) within which six categories were identified. Three of the categories were related to deeply held heritage values and beliefs (family relationships, societal expectations and cultural norms), while the other three (religious beliefs, socio-economic gains and educational values) indicated integration with the host culture. These categories constitute central concerns for the participants and demonstrate what matters to them as a family unit and not as in iduals. We conclude that a selective process of “prioritising family needs” determines the acculturation strategy of sub-Saharan African migrant families, aiding the fulfilment of their migration goals, ensuring effective functioning of the family unit, and enabling them to be productive members of their local community.

Abstract: The main objective of this study was to compare the effect of supplementing beef cattle with Desmanthus virgatus cv. JCU2, D. bicornutus cv. JCU4, D. leptophyllus cv. JCU7 and lucerne on in vivo methane (CH4) emissions measured by open-circuit respiration chambers (OC) or the GreenFeed emission monitoring (GEM) system. Experiment 1 employed OC and utilized sixteen yearling Brangus steers fed a basal diet of Rhodes grass (Chloris gayana) hay in four treatments—the three Desmanthus cultivars and lucerne (Medicago sativa) at 30% dry matter intake (DMI). Polyethylene glycol (PEG) was added to the diets to neutralize tannin binding and explore the effect on CH4 emissions. Experiment 2 employed GEM and utilized forty-eight animals allocated to four treatments including a basal diet of Rhodes grass hay plus the three Desmanthus cultivars in equal proportions at 0%, 15%, 30% and 45% DMI. Lucerne was added to equilibrate crude protein content in all treatments. Experiment 1 showed no difference in CH4 emissions between the Desmanthus cultivars, between Desmanthus and lucerne or between Desmanthus and the basal diet. Experiment 2 showed an increase in CH4 emissions in the three levels containing Desmanthus. It is concluded that on high-quality diets, Desmanthus does not reduce CH4 emissions.

Abstract: This study evaluated the change in nutritive value and in situ degradability of Desmanthus spp. (desmanthus) cultivars JCU2 D. virgatus, JCU4 D. bicornutus and JCU7 D. leptophyllus harvested at varying maturity stages to test the hypothesis that the nutritive value and in situ degradability of desmanthus differ between cultivars and with maturity stage at harvest. In Experiment 1, desmanthus was harvested at 11, 38, 72 and 103 days of regrowth (maturity), separated into the leaf and stem portion, dried and analysed for dry matter (DM) and chemical composition. In Experiment 2, desmanthus was harvested 78, 122 and 168 days after planting (maturity). S les were dried, and DM, crude protein (CP) and neutral detergent fibre (NDF) and acid detergent fibre (ADF) degradation were determined using the in situ technique with three fistulated Droughtmaster steers. The results showed an interaction between cultivar and maturity on the leaf to stem mass ratio, leaf CP, stem NDF and the leaf ADF (p ≤ 0.04). The leaf-to-stem mass ratio declined more steeply with maturity in JCU7 compared to JCU2 and JCU4 (p = 0.04), while there was a higher decline in leaf CP of JCU4 than JCU2 and JCU7 (p 0.01). The total potentially degradable fraction of DM and CP did not differ between cultivars (p ≥ 0.30) but declined with maturity (p ≤ 0.04). However, the effective DM degradability at a high particle outflow rate was higher in JCU4 than in JCU7. Taken together, these results indicate that differences exist between cultivars, and higher livestock production may be achieved by utilising the different cultivars in a blend and at earlier maturity stages. Therefore, the hypothesis that nutritive value and in situ degradability of desmanthus differ between cultivars and with maturity stage at harvest was accepted.

Abstract: This article reports a bibliometric analysis of emerging topics in the psychiatric literature indexed in the MEDLINE database as a technique for renewal of clinical training curricula. Summary data of English-language articles indexed in the MEDLINE database between 1971-2018 were downloaded. Emerging topics in nine demi-decades between 1972-1976 and 2012-2016 were identified by the incremental incidence of in idual Medical Subject Headings (MeSH) compared with previous years. Co-word analysis was used to investigate and visualise the relationships between emerging topics in each demi-decade. Summaries of 18 million articles annotated with psychiatric sychological MeSH were retrieved and used to identify emerging topics. Peaks in the number of articles annotated by the top 20 emerging topics in 9 demi-decades coincided with release of the third and fourth editions of the Diagnostic and Statistical Manual which codifies psychiatric diagnoses. Themes emerging from network visualisations of the most common emerging MeSH in each demi-decade were consistent with movements in psychiatric sychological theory and practice since the 1970s, including the recent focus on psychological and social factors implicated in suicide and suicide prevention. The identification of emerging topics within the published medical literature is a viable technique for use in curriculum renewal projects as a counterweight to biases driven by expert judgement. While indices like MEDLINE make the published literature an appealing initial step in building an empirical basis for curriculum development, it also demonstrates the potential value of less public and less structured data, such as health service electronic medical records.

Abstract: There is growing concern that inequities in methods of selection into medical specialties reduce specialist cohort ersity, particularly where measures designed for another purpose are adapted for specialist selection, prioritising reliability over validity. This review examined how empirical measures affect the ersity of specialist selection. The goals were to summarise the groups for which evidence is available, evaluate evidence that measures prioritising reliability over validity contribute to under-representation, and identify novel measures or processes that address under-representation, in order to make recommendations on selection into medical specialties and research required to support ersity. In 2020–1, the authors implemented a comprehensive search strategy across 4 electronic databases (Medline, PsychINFO, Scopus, ERIC) covering years 2000–2020, supplemented with hand-search of key journals and reference lists from identified studies. Articles were screened using explicit inclusion and exclusion criteria designed to focus on empirical measures used in medical specialty selection decisions. Thirty-five articles were included from 1344 retrieved from databases and hand-searches. In order of prevalence these papers addressed the under-representation of women (21/35), international medical graduates (10/35), and race/ethnicity (9/35). Apart from well-powered studies of selection into general practice training in the UK, the literature was exploratory, retrospective, and relied upon convenience s les with limited follow-up. There was preliminary evidence that bias in the measures used for selection into training might contribute to under-representation of some groups. The review did not find convincing evidence that measures prioritising reliability drive under-representation of some groups in medical specialties, although this may be due to limited power analyses. In addition, the review did not identify novel specialist selection methods likely to improve ersity. Nevertheless, significant and ergent efforts are being made to promote the evolution of selection processes that draw on all the erse qualities required for specialist practice serving erse populations. More rigorous prospective research across different national frameworks will be needed to clarify whether eliminating or reducing the weighting of reliable pre-selection academic results in selection decisions will increase or decrease ersity, and whether drawing on a broader range of assessments can achieve both reliable and socially desirable outcomes.

Abstract: This study sought to examine the awareness erception of intercultural competence and institutional intercultural inclusiveness among first year students at an Australian medical school over four consecutive years (2014–2017) to identify existing gaps in the curriculum and proffer recommendations. The study employed an adapted 20-item questionnaire for data collection. The reliability and interrelations of the survey items were examined. Descriptive statistics was used to examine students’ perceptions, while Mann-U Whitney and Kruskal-Wallis tests were used to assess items scores in relation to participant characteristics. Over the 4 years of study, there were 520 respondents with between 53 to 69% response rates per year. Cronbach’s alpha for the instrument was 0.88 and factor analysis showed all items loading strongly on two components. Participants’ mean score on self-reported intercultural competence levels ranged from 3.8–4.6 out of 5 indicating relatively high awareness, valuing and understanding of cultural differences among this group of students. However, their mean scores (3.4–4.2) for institutional intercultural inclusiveness were slightly lower. The instrument used in this study is effective in assessing level of intercultural competence among medical students. However, the results highlight the need for increased institutional support and professional development for faculty members to foster institutional intercultural inclusiveness.

Abstract: Background and objectives: The Australian Defence Force (ADF) engages in combat-related activities in hot climatic conditions, which exposes ADF members to the threat of exertional heat illness (EHI). After an episode of EHI, the heat tolerance test (HTT) is conducted to determine heat tolerance. Heat intolerance is the inability to maintain thermal balance while exercising in a hot environment. This study investigated the predictive roles of in idual characteristics (age, gender, aerobic capacity (VO2max) and body composition) on physiological responses to the HTT in a group comprising ADF personnel and civilian volunteers. Materials and Methods: A quasi-experimental design was used and 52 (38 males and 14 females) participants were recruited from the ADF and the general population for the HTT. Heat intolerance was defined following the standard criteria for the HTT (temperature and heart rate). Data were analysed using inferential statistics. Results: The mean age of the participants was 31.1 ± 11.6 years, and 44% (23 people: 19 males and 4 females) of the participants were heat intolerant. Independent s les T-test showed that body mass index (p = 0.011) and body fat% (p = 0.034) of heat-intolerant participants were significantly higher than their heat-tolerant counterparts. Body surface area to mass ratio (p = 0.005) and aerobic capacity (p = 0.001) were significantly lower in heat-intolerant participants. Regression analyses showed that age, gender, aerobic capacity and body fat% were significant (p 0.001) predictors of heat tolerance outcomes, with R2 values ranging from 0.505 to 0.636. Conclusions: This study showed that aerobic capacity, body fat%, age and gender are predictors of heat intolerance among military and non-military populations. However, there may be a need for future studies to consider identifying other indicators such as clinical biomarkers of heat intolerance, which could be used to develop a more reliable HTT protocol.

Abstract: obile health apps are commonly used to support diabetes self-management (DSM). However, there is limited research assessing whether such apps are able to meet the basic requirements of retaining and engaging users. his study aimed to evaluate participants’ retention and engagement with My Care Hub, a mobile app for DSM. he study employed an explanatory mixed methods design. Participants were people with type 1 or type 2 diabetes who used the health app intervention for 3 weeks. Retention was measured by completion of the postintervention survey. Engagement was measured using system log indices and interviews. Retention and system log indices were presented using descriptive statistics. Transcripts were analyzed using content analysis to develop themes interpreted according to the behavioral intervention technology theory. f the 50 in iduals enrolled, 42 (84%) adhered to the study protocol. System usage data showed multiple and frequent interactions with the app by most of the enrolled participants (42/50, 84%). Two-thirds of participants who inputted data during the first week returned to use the app after week 1 (36/42, 85%) and week 2 (30/42, 71%) of installation. Most daily used features were tracking of blood glucose (BG 28/42, 68%) and accessing educational information (6/42, 13%). The interview results revealed the app’s potential as a behavior change intervention tool, particularly because it eased participants’ self-care efforts and improved their engagement with DSM activities such as BG monitoring, physical exercise, and healthy eating. Participants suggested additional functionalities such as extended access to historical analytic data, automated data transmission from the BG meter, and periodic update of meals and corresponding nutrients to further enhance engagement with the app. he findings of this short-term intervention study suggested acceptable levels of participant retention and engagement with My Care Hub, indicating that it may be a promising tool for extending DSM support and education beyond the confines of a physical clinic.

Abstract: Medical programs are under pressure to maintain currency with scientific and technical advances, as well as prepare graduates for clinical work and a wide range of postgraduate careers. The value of the basic sciences in primary medical education was assessed by exploring the perceived clinical relevance and test performance trends among medical students, interns, residents, and experienced clinicians. A pilot study conducted in 2014 involved administration of a voluntary 60-item multiple-choice question test to 225 medical students and 4 interns. These participants and 26 teaching clinicians rated the items for clinical relevance. In 2016, a similarly constructed test (main study) was made a mandatory formative assessment, attempted by 563 students in years 2, 4, and 6 and by 120 commencing general practice residents. Test scores, performance trends, clinical relevance ratings, and correlations were assessed using relevant parametric and nonparametric tests. Rank order and pass-fail decisions were also reviewed. The mean test scores were 57% (SD 7.1) and 52% (SD 6.1) for the pilot and main studies, respectively. Highest scores were observed in pathology and social sciences. Overall performance increased with increasing year of study. Test scores were positively correlated with perceived relevance. There were moderate correlations ( r = 0.50–0.63 P 0.001) between participants’ scores in the basic science and summative exams. Assessments may be key to fostering relevance and integration of the basic sciences. Benchmarking knowledge retention and result comparisons across topics are useful in program evaluation.

Abstract: Introduction: The efficacy of varenicline as a smoking cessation aid is affected by commonly-occurring issues, such as intolerable adverse events, cravings and withdrawal symptoms, and poor medication adherence. Improvement in quit rates may be achieved through tailoring doses relative to in idual smokers’ behaviours, and previous experiences with smoking cessation medications. Aims: The aim of this review is to evaluate smoking cessation outcomes from published randomised controlled trials that have attempted to improve the efficacy and tolerability of varenicline through modifying its dosage regimen compared to placebo. Methods: A systematic search of the literature up to June 2016 was conducted to identify randomised controlled trials, where varenicline was administered in a regimen not consistent with the current clinical guidelines. Outcome measures evaluated included continuous abstinence rates, changes in cravings, withdrawal symptoms, smoking behaviours, adverse event rates, and premature therapy discontinuations. Results: Ten randomised controlled trials, encompassing four different modifications to standard varenicline therapy, matched the eligibility criteria. Modifications such as the extended duration of therapy and the use of a flexible quit date were effective compared to placebo and have been implemented into some clinical guidelines, whereas other modifications do not appear to produce any benefit for smokers, or require further research to ascertain their suitability for clinical practice. Conclusions: Some varenicline therapy modifications may lead to improvements in efficacy and tolerability. Further research on the effect of modifications such as daily doses higher than 2mg, tapering doses, and the use of extended pre-quit varenicline may advance varenicline therapy outcomes.

Abstract: Current trends suggest that adolescent obesity is an on-going and recurrent decimal that is still on the rise in Australia and the social burden associated with it can significantly cause low self-esteem and lack of confidence in personal body image in adulthood. Nonetheless, evidence-based prevention programs are not widely implemented in schools, even though they are commonplace for easy access to adolescents. The primary objective of this systematic review was to assess the scope and efficacy of adolescent obesity intervention strategies in Australian schools, to guide future research. Seven electronic databases were searched for peer-reviewed school-based intervention articles written in the English language and targeting 12–18-year-old adolescents. Intervention characteristics were extracted, and quality, efficacy and outcome measures were assessed utilizing thirteen studies that met the inclusion criteria for this review. Most of the Australian adolescent obesity research emanated from the State of New South Wales and none were nationwide. Five studies successfully met all the requirements in all measured outcomes, four met at least one measured outcome and the remaining four were unsuccessful. Despite the weak evidence of intervention efficacy for most of the reviewed studies, school-based interventions with multi-component combinations of physical activity, nutrition and alignment to a theory yielded promising results. Our findings point to the need for future research to assess the perceptions of school stakeholders in relation to the barriers and enablers to establishing school-based prevention and intervention programs for adolescents.

Abstract: The general objective of this study was to come up with an appropriate, affordable and locally available crop residue supplementation package that would enhance reproductive performance in small ruminants. Specifically, 28 Red Sokoto weaner does between 3 and 4 months of age weighing between 2 and 3 kg were used in the first experiment to determine the influence of crop residue supplementation on age and weight at puberty as determined by blood progesterone levels. In the second experiment, another 28 adult does (≥2 years old) of the same breed in the same flock with lactation numbers between 1 and 3 were used to determine the length of postpartum acyclic period. In both experiments, a 3 × 2 factorial experimental design comprising three dietary supplements (A, B, C) at two feeding levels (1% and 2% of body weight) fed in addition to a basal diet of Digitaria smutsii hay and natural pasture ad libitum with an unsupplemented negative control group (D) and four goats per treatment was utilized. In ration A, a conventional concentrate supplement consisting of maize, wheat offal, cottonseed cake and bonemeal was utilized in rations B and C, the supplement consisted of guinea‐corn bran, cowpea husk and groundnut haulms and maize offal, groundnut shells and groundnut haulms respectively. Unsupplemented (ration D) weaner does reached puberty at a later age and had lighter body weights than all the others. Weaner does on ration 2A (concentrate fed at 2% of body weight) attained puberty at the earliest age and heaviest body weight, although the age at puberty was not significantly different from those on rations 1A (concentrate fed at 1% body weight), 1C and 2C. Blood progesterone profiles before and after puberty ranged from 0.05 to 9.0 ng/ml, respectively, and was highest in does fed rations A and C and least in the unsupplemented does. The mean interval between kidding and initiation of ovarian activity was 54.28 ± 17.61 days and the mean interval between kidding and conception was 63.04 ± 25.34 days. Only 25% of the unsupplemented does conceived again during the period under study compared with 100% in rations 1A, 2A, 1C and 2C 75% in ration 2B and 50% in ration 1B. It was concluded that implementation of supplementary feeding in the dry season improves reproductive performance in the Red Sokoto doe. Furthermore, ration C, a crop residue‐based ration, was a suitable dry season supplementation alternative to the expensive conventional concentrate ration for the smallholder goat farmer in the subhumid tropics of Nigeria.

Abstract: Outcomes-based education requires active student learning with assessment strategies that foster deep approaches to learning, which are often influenced by students' perceptions of assessment. We aimed to investigate the perceptions of pharmacy students at an Australian university about their experiences of assessment and its impact on their learning. A mixed-methods study was conducted involving a self-administered questionnaire and semi-structured focus groups. Descriptive statistics were used to rate the perceived value of different assessment tools and confirmed by themes arising from the focus groups. Examination results over a five-year period were also collated to assess congruence between perceptions and academic performance. From the 123 questionnaire and nine focus group participants, short-answer questions were the most positively-received form of assessment due to students being able to demonstrate and receive marks for partial knowledge. Multiple-choice questions received mixed response as they were cited as being useful in assessing student knowledge but potentially difficult to interpret/answer correctly. Reflective pieces received the lowest ratings and were considered the least beneficial. Key identified themes were ensuring quality assurance of assessment processes, use of authentic assessment, timely feedback, and appropriate match between workload and assessment weightings. Overall, there was congruence between students' exam scores and their perceptions of the different assessment types. Strategic planning and delivery of correctly-weighted authentic assessments with the provision of constructive feedback are key elements for active engagement of students and achievement of life-long learning outcomes.

Abstract: The Australian dairy sheep industry is small and mostly based on a natural grass grazing system, which can limit productivity. The current study tested different plant oil-infused and rumen protected polyunsaturated fats and their interactions with sire breeds to improve lactation traits and body condition scores (BCS) of ewes grazing low quality pastures. It was hypothesised that supplementing lactating ewe’s diets with plant-derived polyunsaturated oils would improve milk production and composition without compromising BCS. Sixty ewes (n = 10/treatment) in mid-lactation, balanced by sire breed, parity, milk yield, body condition score, and liveweight, were supplemented with: (1) control: wheat-based pellets without oil inclusion wheat-based pellets including (2) canola oil (CO) (3) rice bran oil (RBO) (4) flaxseed oil (FSO) (5) safflower oil (SFO) and (6) rumen protected marine oil containing eicosapentaenoic acid and docosahexaenoic acid (RPO). Except for the control group, all supplementary diets included the same level of 50 mL/kg DM of oil and all diets were isocaloric and isonitrogenous. Experimental animals were grazed in the same paddock with ad libitum access to pasture, hay, and water during the 10-week study. RPO was the most effective diet that enhanced milk, fat, and protein yields by approximately 30%, 13%, and 31%, respectively (p 0.0001). A significant increase in milk production was also observed with CO, RBO, and SFO treatments (p 0.0001). Breed significantly influenced animal performance with higher milk yields recorded for crossbred Awassi × East Friesian (AW × EF) (578 g/day) vs. purebred Awassi (452 g/day) (p 0.0001). This study provides empirical evidence for the use of rumen-protected and plant-derived oil-infused pellets as supplements under low quality pasture grazing conditions to improve the production performance of purebred Awassi and crossbred AW × EF ewes.

Abstract: We aimed to identify the experiences of Australian community pharmacists with smokers and their associated perceptions of effective health warnings on in idual cigarette sticks. A mixed-methods online survey was distributed to Australian pharmacists through pharmacy-specific social media pages, and the Pharmaceutical Society of Australia, followed by semi-structured face-to-face interviews with pharmacists in Townsville, Australia, who were purposively s led. The interviews continued until data saturation was achieved. Participants described their experiences with smokers, perceptions and effectiveness ratings of current cigarette packaging warnings, and 12 text warnings ( ided into four themes) on in idual cigarette sticks, and their general opinions on effective anti-tobacco health warnings. Seventy pharmacists participated in the survey and 17 pharmacists in the interviews. Both groups of pharmacists cited smoking-related personal or close-contact illness, pressure by family members or physicians and the financial costs of smoking as being the main drivers for quit attempts. Most interviewed pharmacists interact with smokers several times per week. Cigarette stick warnings describing mortality consequences (especially the ‘minutes of life lost’ warning) and the financial consequences of tobacco use were rated as significantly more effective than current packaging warnings (odds ratio [OR] = 2.23 95% confidence interval [CI]: 1.12–4.12, P = 0.02, and 1.97 95%CI: 1.01–3.84, P = 0.04, respectively). Pharmacists have considerable experience assisting smokers with quitting and based on these experiences believe that novel and tangible health warnings on cigarette sticks may be an effective future measure to combat tobacco use. Further research on the opinions of a more erse range of health professionals and the general community will generate more robust findings regarding this method of intervention.

Abstract: b i Objectives: /i /b Blended learning has been presented as a promising learner-centred model that emphasises the learning outcome rather than the process of education, but it can negatively affect learners’ engagement with learning. b i Subject and Methods: /i /b Using a mixed-methods approach, this study aimed to determine the significant predictors of learning satisfaction and to evaluate the experiences of medical students with the different domains of an introduced blended integrated learning approach. b i Results: /i /b The survey was administered to 92 respondents with a mean age of 20.5 years. Male students had significantly higher computer self-efficacy and overall learner satisfaction ratings than their female counterparts. Multiple regression analysis showed that gender (student characteristics), performance expectations (cognitive factors), and learning climate (social environment) were predictors of the perceived satisfaction of learners. b i Conclusion: /i /b Wider integration of blended learning into pre-clinical undergraduate medical education could enhance the shift towards competency-based education and life-long learning among medical students. However, effective implementation would depend largely on student characteristics, as well as environmental and cognitive components of the delivery method.

Abstract: Adolescent obesity is a complex multifactorial disease with a combination of environmental, behavioral, psychosocial, biological, cultural and genetic determinants. It remains a global public health issue that presents a major challenge to chronic disease prevention and health into adulthood. Schools have a rich opportunity to improve youth health and tackle obesity, yet they face barriers in fulfilling this function. This study investigated school stakeholders’ beliefs and perceptions of the barriers and enablers currently experienced by schools, as well as their recommendations towards preventing adolescent obesity. A sequential explanatory mixed-methods study design was utilised with surveys administered for the quantitative phase and in idual interviews for the qualitative phase. Descriptive statistics and inductive thematic analyses were utilised for the survey and interview data, respectively. Triangulation of findings from the quantitative and qualitative phases aided in the better understanding and integration of the overall results. In total, 60 school stakeholders (52 subject teachers, 3 senior teachers and 5 heads of department) from both independent and public high schools in Queensland, Australia responded to the survey, while 14 respondents participated in the interviews. The main perceived causes of obesity were poor eating habits and sedentary lifestyle. Highlighted barriers were busy timetables, shortage of trained staff and funding, lack of robustness in the introduction and implementation of school interventions and insufficient motivation of learners to participate in obesity prevention programs. Enabling factors included parental support, easy access to fitness equipment during recess, supportive government policies, provision of healthier school tuck shop menu options and elimination of sugary drinks from vending machines. A model for the prevention of adolescent obesity was developed based on participants’ perceptions. Tripartite collaboration between the school, government and parents was perceived as fundamental to preventing adolescent obesity. Strategies targeting nutrition, physical activity and overall health, including parental education on health, formal health talks in schools by health professionals and better-targeted advertisement encouraging healthy lifestyle choices, were identified as essential for improved adolescent health outcomes.

Abstract: Clinical experience is a crucial component of dental education as it prepares students for real‐world practice. Our study aimed to investigate the transition from preclinical to clinical training experiences of dental students at a regional Australian dental school. A mixed‐methods study was conducted using a survey and focus groups. Participants were dental students who recently transitioned into clinical training. Survey data were analysed quantitatively using descriptive statistics, whilst the qualitative data were thematically analysed using the conceptual framework of organisational socialisation theory (OST). Forty‐eight of the 69 students in the cohort completed the survey and 10 participated in the focus groups. The quantitative findings revealed that the transition was perceived to be abrupt and associated with a heavy workload. However, orientation sessions and engaging in chairside teaching made transitioning into clinical studies easier. The qualitative findings revealed that the transition process occurred in three phases. In phase 1, participants navigated the educational and social challenges using developmental characteristics such as resilience and positivity. Lessons learnt in phase 1 were used to make necessary learning adjustments in phase 2 and this subsequently enhanced developmental growth in the final phase, which helped ease the transition. This study confirms that transitioning into clinical training can be complex. However, the educational and socialisation challenges associated with the transition can provide stimulating developmental learning opportunities that advance students’ adjustments to the clinical environment with positive, empowering and motivational outcomes that facilitate a smooth transition.

Abstract: The transition experience into university can be challenging for health profession students as they are required to rapidly learn erse and adaptable problem solving skills and advanced reflective thinking processes which are necessary to address complex patient-care problems, particularly in the face of uncertainty within a dynamic and rapidly evolving learning environment. A mixed-methods study was conducted to identify factors influencing this transition for first-year medical, dental, and pharmacy students at a regional Australian university. The Student Adaption to College Questionnaire (SACQ) examined participants’ levels of adjustment to university, while Schlossberg’s 4 S transition model was utilised in a framework analysis of the focus group and interview responses. Complete survey responses were obtained from 198 students, 17 of whom also participated in focus group discussions or interviews. Mean adjustment ratings obtained from the SACQ responses were academic (6.09 ± 1.3) personal-emotional (5.53 ± 1.55), social (6.30 ± 1.38), and institutional attachment (6.96 ± 1.6). These results indicate that the personal and emotional aspects of this transition were more challenging for the students. Analysis of the qualitative data revealed that generally, for these highly motivated health-professions students, dropping out of university was not an option and this had a positive influence on their ability to adjust to their new learning environment. Nonetheless, the transition involved role change school-leavers were excited about their newly found independence, while for mature-aged students, returning to university allowed them to pursue their lifelong dreams. Adjustment was more challenging for international, mature-aged and female students, with personal and social factors influencing the transition for each of these demographic groups. To facilitate smooth transition into university, tertiary education institutions must consider tailored on-going support strategies that promote social interaction among students with varied backgrounds and personal characteristics.

Abstract: The main objective of this study was to investigate the effect of supplementing beef cattle with incremental levels of Desmanthus leptophyllus cv. JCU1 and Desmanthus bicornutus cv. JCU4 on in vivo methane (CH4) emissions and the role of tannins in rumen fermentation. Fourteen yearling Droughtmaster steers were allocated to each of the two Desmanthus species and offered a basal diet of Rhodes grass (Chloris gayana) hay plus fresh Desmanthus at 0%, 15%, 22%, and 31% of dry matter intake (DMI). The 15% and 31% Desmanthus periods lasted 21 days and the 22 and 0% Desmanthus periods, 14 days. Methane production was measured by open-circuit gas exchange in the last two days of each period. The results showed a linear increase in DMI and reduction in CH4 yield with the increasing level of Desmanthus and subsequently condensed tannins in the diet. The added tannin binder polyethylene glycol-4000 did not affect CH4 yield but increased rumen NH3-N and iso-acid concentrations. Therefore, on a low-quality diet, Desmanthus has the potential to increase intake and reduce CH4 emissions. Even though its tannins can bind rumen proteins, the beef cattle anti-methanogenic response to supplementation with Desmanthus may be a combination of rumen fermentation and tannin effects.

Abstract: The continuous increase in the prevalence of hypertension in Ghana has led to various interventions aimed at controlling the disease burden. Nonetheless, these interventions have yielded poor health outcomes. Subsequently, the Pan-African Society of Cardiology (PASCAR), established a 10-point action plan for inclusion in policies to aid control of hypertension. This scoping review assessed the adherence of health policies to the 10-point action plan towards hypertension control/reduction in Ghana. Eight health policies met the inclusion criteria and were assessed. The programme evaluation and policy design framework were used for synthesis and analysis of extracted data. Overall, there was poor adherence to hypertension control observed in the policies. Specifically, there were low levels of integrating hypertension control/reduction measures, a poor task-sharing approach, and poor financial resource allocations to tackle hypertension control/reduction in most of the policies. There was also low support for research to produce evidence to guide future interventions. For Ghana to achieve the global target of reducing hypertension by the year 2025, its health policies must adhere to evidence-based interventions in hypertension management/control. The study recommends a follow-up study among hypertension patients and healthcare professionals to evaluate the factors militating against hypertension management/control in Ghana.

Abstract: This study explored the identification of single nucleotide polymorphisms (SNP) in fatty acid binding protein 4 (FABP4), stearoyl-CoA desaturase (SCD), and fatty acid synthase (FASN) genes that may influence the carcass traits of tropical crossbred beef cattle. The hypothesis tested was that SNP in the FABP4, SCD, and FASN genes are associated with chiller-assessed carcass traits of tropically adapted northern Australian crossbred beef cattle. Fifty Bos indicus and Bos taurus crossbred steers were backgrounded on either buffel grass only, or buffel grass and desmanthus mixed pastures for 147 days and finished in a commercial feedlot for 110 days. Steers were slaughtered within 48 h of leaving the feedlot within a lairage period not exceeding 12 h and carcasses graded 12 h after slaughter. Next-generation sequencing of the FASN, FABP4, and SCD genes identified multiple SNP loci that were correlated and significantly associated with carcass traits. The FABP4 g.44677205A G locus was significantly associated with hump height and correlated with loin eye muscle area (EMA p 0.05). Polymorphism in the SCD gene g.21275851C A locus was associated with subcutaneous fat depth and marbling score (p 0.05). The CC genotype had a higher subcutaneous fat depth and marbling score (p 0.05) than the AA genotype. Significant correlations were observed between carcass marbling score and subcutaneous fat depth within the FASN SNP locus (p 0.05). Therefore, the hypothesis that SNP in the FABP4, SCD, and FASN genes are associated with chiller-assessed carcass traits of tropically adapted northern Australian crossbred beef cattle was accepted. These findings suggest that SNP in the FABP4, SCD, and FASN genes may be used in carcass grading and meat quality improvement through marker-assisted selection of northern Australian crossbred beef cattle.

Abstract: This study investigated live animal performance and carcass characteristics of Australian prime lambs fed oil based polyunsaturated fatty acid (PUFA) enriched pellets in a feedlot system. The tested hypothesis was that supplementation of lambs with a variety of dietary oil based PUFA enriched pellets would enhance growth and carcass characteristics compared with the control lambs fed only with lucerne hay. Seventy-two, 6 months old White Suffolk x Corriedale first-cross prime lambs with an average liveweight (LWT) of 35.7 ± 0.9 kg were allocated to six treatment groups in a completely randomised experimental design. The treatments were: (1) control: lucerne hay only or lucerne hay plus wheat-based pellets infused with 50 mL/kg dry matter (DM) of oils from (2) rice bran (RBO) (3) canola (CO) (4) rumen protected (RPO) (5) flaxseed (FO) and (6) safflower (SO) dietary sources. All lambs had ad libitum access to lucerne hay and clean fresh water. Supplemented lambs were fed 1 kg of pellet/head/day for 10 weeks. Feed intake, final LWT, average daily gain (ADG), body conformation and carcass characteristics of lambs in the supplemented groups were all greater than for the control group. SO lambs had the lowest ADG of 190.3 g/day. RBO and CO treatments had the lowest feed cost per unit gain of AU$3.0/kg. Supplemented lambs had similar over the hooks (OTH) incomes that were all higher than that of the control group. This empirical evidence-based data demonstrated that supplementation of lambs with RBO and CO had comparatively lower feed costs without compromising ADG, carcass characteristics and OTH income.

Abstract: here is increased research interest in the use of mobile phone apps to support diabetes management. However, there are ergent views on what constitute the minimum standards for inclusion in the development of mobile phone apps. Mobile phone apps require an evidence-based approach to development which will consequently impact on their effectiveness. Therefore, comprehensive information on developmental considerations could help designers and researchers to develop innovative and effective patient-centered self-management mobile phone apps for diabetes patients. his systematic review examined the developmental considerations adopted in trials that engaged mobile phone applications for diabetes self-management. comprehensive search strategy was implemented across 5 electronic databases Medline, Scopus, Social Science Citation Index, the Cochrane Central Register of Controlled Trials and Cumulative Index of Nursing and Allied Health Literature (CINALHL) and supplemented by reference list from identified studies. Study quality was evaluated using the Joanna Briggs Critical appraisal checklist for trials. Information on developmental factors (health behavioral theory, functionality, pilot testing, user and clinical expert involvements, data privacy and app security) were assessed across experimental studies using a template developed for the review. total of 11 studies (10 randomized controlled trials and 1 quasi-experimental trial) that fitted the inclusion criteria were identified. All the included studies had the functionality of self-monitoring of blood glucose. However, only some of them included functions for data analytics (7/11, 63.6%), education (6/11, 54.5%) and reminder (6/11, 54.5%). There were 5/11(45.5%) studies with significantly improved glycosylated hemoglobin in the intervention groups where educational functionality was present in the apps used in the 5 trials. Only 1 (1/11, 9.1%) study considered health behavioral theory and user involvement, while 2 (2/11, 18.1%) other studies reported the involvement of clinical experts in the development of their apps. There were 4 (4/11, 36.4%) studies which referred to data security and privacy considerations during their app development while 7 (7/12, 63.6%) studies provided information on pilot testing of apps before use in the full trial. Overall, none of the studies provided information on all developmental factors assessed in the review. here is a lack of elaborate and detailed information in the literature regarding the factors considered in the development of apps used as interventions for diabetes self-management. Documentation and inclusion of such vital information will foster a transparent and shared decision-making process that will ultimately lead to the development of practical and user-friendly self-management apps that can enhance the quality of life for diabetes patients.

Abstract: Physical activity (PA) is a cost-effective and non-pharmacological foundation for the prevention and management of chronic and complex diseases. Healthcare professionals could be viable conduits for PA promotion. However, the evidence regarding the effectiveness and benefits of the current forms of PA promotion are inconclusive. Healthcare professionals’ perceptions on key determinants impact on the optimum promotion of PA were explored in this review. Thirty-four (34) studies were identified after systematically searching seven databases for peer-reviewed articles published within the last decade. PA advice or counselling was the most recorded form of PA promotion, limited counselling time was the most reported obstacle while providing incentives was viewed as a key facilitator. There is widespread consensus among healthcare professionals (HCPs) on some aspects of PA promotion. Utilisation of all PA promotional pathways to their full potential could be an essential turning point towards the optimal success of PA promotional goals. Hence, strategies are required to broaden chronic disease treatment methods to include preventive and integrative PA promotion approaches particularly, between frontline HCPs (e.g., GPs) and PA specialists (e.g., EPs). Future studies could explore the functionality of GP to EP referral pathways to determining what currently works and areas requiring further development.

Abstract: Exertional heat illness (EHI) is an occupational hazard among military personnel. This systematic review describes the incidence, risk factors, clinical manifestations, and biomarkers of EHI in the military. Six databases from inception to 28 May 2020 were systematically reviewed using the PRISMA guidelines. Forty-one articles met the inclusion criteria and the incidence of EHI ranged from 0.2 to 10.5 per 1000 person years, while the prevalence rates ranged from 0.3% to 9.3%. Intrinsic risk factors influencing EHI were gender, physical fitness, obesity, previous history of heat illness, and motivation, while the extrinsic factors included hot environmental conditions and service unit. Evidence suggests that loss of consciousness, absence of sweating and confusion were the common clinical features of exertional heat stroke (EHS). The mean core temperature ranged from 40 to 41.6 °C, while elevated levels of creatine phosphokinase, liver enzymes, and creatinine were common biochemical markers of EHS. The findings of the review suggest a variation in the incidence of EHI among military populations possibly due to the varying definitions used. Although some risk factors of EHI were identified, more analytical studies are needed to investigate the association between EHI and other important factors such as acclimatisation and occlusive clothing.

Abstract: Background: Varenicline remains the most effective medication for smoking cessation however, discontinuation as a result of adverse events negatively impacts medication adherence, and the likelihood of a quit attempt being successful. Post-treatment cravings and withdrawal symptoms may also occur, increasing the likelihood of treatment failure, due to lapse and relapse after achieving initial abstinence. This protocol details a trial investigating changes in the effectiveness and tolerability of varenicline, when an extended step-up and step-down regimen are used. Methods: A phase four, randomised, double-blinded, placebo-controlled single-centre study with a treatment period of 16 weeks, and follow-up period of 12 weeks will be conducted. Up to 201 participants will be enrolled and allocated in a 1:1:1 ratio to a placebo-matching control group, step-up, or step-down intervention group, all receiving behavioural counselling and quitting advice. Participants will be contacted weekly during treatment and fortnightly during follow-up. Eligible participants are smokers over 18 years old, willing to quit smoking, are able to attend clinic visits, and have no uncontrolled or serious medical issues. Primary outcome measures are comparisons of biochemically confirmed continuous abstinence rates, 7-day point prevalence abstinence rates, and the frequency, severity and duration of adverse events, cravings and withdrawal symptoms. Secondary outcome measures are participant adherence to the study medication throughout treatment, and comparisons of changes in smoking satisfaction and reward. Effects of each regimen on smoking cessation will be assessed by logistic regression, with survival analyses used for a more precise estimate of when cessation occurs. Primary endpoints will then be compared using a general linear model. Australian New Zealand Clinical Trials Registry: ACTRN12616000802404p

Abstract: There are numerous theories on parenting styles, however, they are Western-oriented and may not be applicable to collectivist non-Western societies. A qualitative study which utilised semi-structured interviews was conducted to explore the perceived parenting roles of 26 Sub-Saharan African (SSA) migrant parents (both humanitarian and professional migrants) in their children’s career pathways after they migrated to Australia. Data were analysed using grounded theory methods and this process facilitated the creation of a new framework to provide an in-depth understanding of how SSA parenting styles informed the migrant children’s career choices while living in Australia. The study revealed that most SSA migrant parents maintained their style of parenting as used in their home countries. Interestingly, some parents adapted their parenting styles due to their perceptions of changed circumstances within the host country. Other parents, who would normally be authoritative, became trustful due to their perceived lack of educational expertise to guide their children. Conversely, some other parents who would normally be authoritarian employed wily tactics in influencing their children’s decision, so as to circumvent the strict Australian legal framework around children’s rights. Irrespective of parenting style applied, all the parents aimed to either guide or direct their children’s educational and career development to ensure that they become economically productive adults. From the discourse of the SSA migrants’ perceptions of their parental role, we offer potential explanations for what underpins their parenting preferences and the rippling effects on their children’s career trajectories. Direction for areas of continued research are presented, and implications of the findings are discussed.

Abstract: Heat intolerance is the inability to withstand heat stress and this may occur due to exertional heat stroke (EHS). However, it is unknown if heat intolerance is associated with immune and hormonal disturbances. This study investigates haematological, biochemical and hormonal biomarkers related to heat intolerance and EHS in military and civilian volunteers. A quasi-experimental pre-and post-test design was used, with participants drawn from the Australian Defence Force (ADF) and the general populace. Blood s les were collected and analysed for biomarkers. Inferential statistics compared the biomarkers between the groups. Changes in alanine amino transaminase (p = 0.034), creatine kinase (0.044), cortisol (p = 0.041) and creatinine (p 0.001) differed between the heat-intolerant and heat-tolerant groups. Participants with a history of EHS showed significant changes in creatinine (p = 0.022) and urea (p = 0.0031) compared to those without EHS history. Predictors of heat intolerance were increasing post-HTT creatinine and cortisol (OR = 1.177, p = 0.011 and OR = 1.015, p = 0.003 respectively). Conclusively, EHS history is associated with changes in creatinine and urea concentrations, while the predictors of heat intolerance are creatinine and cortisol. However, further exploration of other biomarkers, such as genetic polymorphism, is needed.

Abstract: Physical activity (PA) has been identified as an essential tool for the prevention and management of multi-morbidity in patients. Coordination of patients’ care through interventions like physical activity referral schemes (PARS) could foster the utilization of PA. This study explored the views of General Practitioners (GPs) and Exercise Physiologists (EPs) as key stakeholders, for optimizing patient care and efficiency of PARS. Sequential explanatory mixed methods design was used to explore the perceptions of these health professionals on PA and coordination strategies for PARS patient care. Data analyses included descriptive and inferential statistics for questionnaires and theoretical framework analysis for the semi-structured interviews. Participants demonstrated a good knowledge of PA and valued PARS. However, the findings unravelled external factors, inter-organisational mechanisms, and relational coordination obstacles that hinder efficient coordination of PARS patient care and delay/limit beneficial health outcomes for patients. Incentivising the PARS initiative and empowering patients to seek referral into the programme, are strategies that could boost PARS efficiency. Improving inter-professional relationships between GPs and EPs could lead to enhanced PARS functionality and efficient coordination of care for patients with chronic diseases.

Abstract: Lipid metabolism, carcass characteristics and fatty acid (FA) composition of the Longissimus dorsi (loin eye) muscle were evaluated in tropical crossbred steers backgrounded on Desmanthus spp. (desmanthus) with or without feedlot finishing. It was hypothesized that steers backgrounded on isonitrogenous diets augmented with incremental proportions of desmanthus will produce carcasses with similar characteristics and FA composition. Forty-eight Brahman, Charbray and Droughtmaster crossbred beef steers were backgrounded for 140 days on Rhodes grass (Chloris gayana) hay augmented with 0, 15, 30 or 45 percent desmanthus on dry matter basis. Lucerne (Medicago sativa) hay was added to the 0, 15 and 30 percent desmanthus diets to ensure that they were isonitrogenous with the 45 percent desmanthus diet. After backgrounding, the two heaviest steers in each pen were slaughtered and the rest were finished in the feedlot for 95 days before slaughter. Muscle biopsy s les were taken at the beginning and end of the backgrounding phase. Carcasses were s led at slaughter for intramuscular fat (IMF) content, fat melting point (FMP) and FA composition analyses. Increasing the proportion of desmanthus in the diet led to a linear increase in docosanoic acid (p = 0.04) and omega-6/omega-3 polyunsaturated FA ratio (n-6/n-3 PUFA p = 0.01), while docosahexaenoic acid decreased linearly (p = 0.01). Feedlot finishing increased hot carcass weight, subcutaneous fat depth at the P8 site and dressing percentage (p ≤ 0.04). The n-6/n-3 PUFA ratio was within the recommended 5 for human diets. IMF was within the consumer-preferred ≥3% level for palatability. The hypothesis that steers backgrounded on isonitrogenous diets augmented with incremental proportions of desmanthus will produce similar carcass characteristics and FA composition was accepted. These findings indicate that a combination of tropical beef cattle backgrounding on desmanthus augmented forage and short-term feedlot finishing produces healthy and highly palatable meat.

Abstract: Introduction: The transition to clinical studies can be a source of stress, though little is known about how pharmacy students manage this transition. This mixed-methods study investigated factors influencing student transition from pre-clinical to clinical years of an Australian pharmacy degree. Methods: Students rated and discussed their confidence in performing pharmacy-related skills, factors influencing their ability to carry out these skills and key enabling factors and barriers that influenced their transition. Results: Differences in teaching and assessment style and placement workload affected the transition experience. Self-confidence in the clinical learning environment was enhanced by patient contact, previous pharmacy work experience, case-based learning and supportive placement supervisors. A perceived lack of relevance of pre-clinical learning and heavy workload during placement were major barriers to a smooth transition. Conclusions: Support systems are essential to foster transition into the clinical learning environment with confidence and effective application of theoretical knowledge to real-world practice.

Abstract: The parameters investigated in this study with the objective of evaluating growth, lactation and reproductive performances, included birth weight, litter size, 0-90 days gain and average daily gain of kids as well as the milk yield and progesterone profile of Red Sokoto does supplemented with crop-residue based rations during the long-dry period of the subhumid zone in Nigeria. A total of 7 treatments of 4 goats each was utilised. All treatment groups had a basal diet of Digitaria smutsii hay and natural pasture ad libitum. Ration A supplemented with the conventional concentrate was used as the positive control rations B and C were supplemented with crop residues and ration D without supplement was used as the negative control. Supplementation with concentrate and crop residues significantly increased (P < 0.05) the birth weight and liveweight gains of kids, but littersize was unaffected. The heaviest kids at birth (1.3-1.4 kg) were from does in treatments 1A, 2A and 2C, while does in treatments 1B, 2B, 1C and D had the lightest kids (1.07-1.18 kg). The highest gains of 53.9 g x day(-1) were recorded in treatment 2A and the least (32.4 g x day(-1)) in treatment 1B. Supplementation also significantly influenced (P < 0.01) the daily milk yield of dams over the 90-day period of the dry season. All the does had similar progesterone profiles from late gestation through parturition to early lactation irrespective of their treatment group. It was concluded that ration C fed at the 2% level is a good and affordable supplementary feed package for increased birth weight and preweaning gains in kids for meat production.

Abstract: Evidence in the literature suggests that satisfaction with postgraduate general practice (GP) training is associated with the quality of the educational environment. This study aimed to examine GP registrars’ level of satisfaction with a distributed model of training in a regional educational environment and investigate the relationship between satisfaction and academic performance. A longitudinal 3-year study was conducted among GP registrars at James Cook University using a sequential explanatory mixed methods research design. GP registrars’ satisfaction was obtained using the scan of postgraduate educational environment domains tool. A focus group discussion was conducted to explore GP registrars’ perceptions of satisfaction with the educational environment. James Cook University General Practice Training (JCU GPT) programme. Six hundred and fifty one (651) GP registrars enrolled between 2016 and 2018 at JCU GPT programme. 651 registrars completed the satisfaction survey between 2016 and 2018. Overall, 92% of the registrars were satisfied with the educational training environment. Registrars who had become fellows reported higher satisfaction levels compared with those who were still in training (mean=4.39 vs 4.20, p=0.001). However, academic performance had no impact on level of satisfaction with the educational environment. Similarly, practice location did not influence registrars’ satisfaction rates. Four themes (rich rural/remote educational environment, supportive learning environment, readiness to continue with rural practice and practice culture) emerged from the thematic data analysis. A clinical learning environment that focuses on and supports in idual learning needs is vital for effective postgraduate medical training. This study suggests that JCU GPT programme’s distributed model fostered a satisfying and supportive training environment with rich educational experiences that enhance retention of GP registrars in rural/remote North Queensland, Australia. The findings of this study may be applicable to other settings with similar training models.

Abstract: Dietary crude protein and dry matter digestibility are among the major factors limiting feed intake and weight gain of cattle grazing native and improved pastures in the subtropics of Northern Australia during the dry season. Incorporating a suitable legume into grasses improves pasture quality and cattle weight gain, but only a limited number of legume pastures can establish and persist in cracking clay soils. This study aimed to evaluate the effect of Desmanthus inclusion in buffel grass (Cenchrus ciliaris) pastures on the plasma metabolite profile and growth performance of grazing beef cattle during the dry season. We hypothesised that backgrounding steers on buffel grass-Desmanthus mixed pastures would elicit significant changes in plasma glucose, bilirubin, creatinine, non-esterified fatty acids and β-hydroxybutyrate, resulting in higher liveweight gains than in steers on buffel grass only pastures. Four hundred tropical composite steers were assigned to buffel grass only (n = 200) or buffel grass oversown with Desmanthus (11.5% initial sward dry matter) pastures (n = 200) and grazed for 147 days during the dry season. Desmanthus accounted for 6.2% sward dry matter at the end of grazing period. Plasma metabolites results showed that changes in β-hydroxybutyrate, creatinine, bilirubin, glucose and non-esterified fatty acids were within the expected normal range for all the steers, indicating that with or without Desmanthus inclusion in the diet of grazing steers, animal health status was not compromised. It was also evident that Desmanthus inclusion in buffel grass pastures had no impact on the plasma metabolite profile, liveweight and daily weight gain of grazing steers. Therefore, our tested hypothesis of higher changes in plasma metabolite profile and higher liveweight gains due to backgrounding on low-level buffel grass-Desmanthus mixed pastures does not hold.

Abstract: A needs analysis study for curriculum reform in basic sciences was conducted at Melaka Manipal Medical College, India, by means of a formative assessment method, namely Basic Science Retention Examination (BSRE). Students participated in a BSRE, which comprised recall and clinical multiple-choice questions in six discipline areas. They also rated the clinical relevance of each question and provided responses to three open-text questions about the exam. Pass rates were determined clinical relevance ratings and performance scores were compared between recall type and clinical questions to test students’ level of clinical application of basic science knowledge. Text comments were thematically analyzed to identify recurring themes. Only one-third of students passed the BSRE (32.2%). Students performed better in recall questions compared with clinical questions in anatomy (51.0 vs. 40.2%), pathology (45.1 vs. 38.1%), pharmacology (41.8 vs. 31.7%), and biochemistry (43.5 vs. 26.9%). In physiology, students performed better in clinical questions compared with the recall type (56.2 vs. 45.8%). Students’ response to BSRE was positive. The findings imply that transfer of basic science knowledge was poor, and that assessment methods should emphasize clinical application of basic science knowledge.

Abstract: This study aimed to identify single nucleotide polymorphisms (SNP) in lipogenic genes of northern Australian tropically adapted crossbred beef cattle and to evaluate associations with healthy lipid traits of the Longissimus dorsi (loin eye) muscle. The hypothesis tested was that there are significant associations between SNP loci encoding for the fatty acid binding protein 4 (FABP4), stearoyl-CoA desaturase (SCD) and fatty acid synthase (FASN) genes and human health beneficial omega-3 long-chain polyunsaturated fatty acids (ω3 LC-PUFA) within the loin eye muscle of northern Australian crossbred beef cattle. Brahman, Charbray, and Droughtmaster crossbred steers were fed on Rhodes grass hay augmented with desmanthus, lucerne, or both, for 140 days and the loin eye muscle s led for intramuscular fat (IMF), fat melting point (FMP), and fatty acid composition. Polymorphisms in FABP4, SCD, and FASN genes with significant effects on lipid traits were identified with next-generation sequencing. The GG genotype at the FABP4 g.44677239C G locus was associated with higher proportion of linoleic acid than the CC and CG genotypes (p 0.05). Multiple comparisons of genotypes at the SCD g.21266629G T locus indicated that the TT genotype had significantly higher eicosapentaenoic, docosapentaenoic, and docosahexaenoic acids than GG genotype (p 0.05). Significant correlations (p 0.05) between FASN SNP and IMF, saturated and monounsaturated fatty acids were observed. These results provide insights into the contribution of lipogenic genes to intramuscular fat deposition and SNP marker-assisted selection for improvement of meat-eating quality, with emphasis on alternate and sustainable sources of ω3 LC-PUFA, in northern Australian tropical crossbred beef cattle, hence an acceptance of the tested hypothesis.

Abstract: Mobile health apps are commonly used to support diabetes self-management (DSM). However, there is limited research assessing whether such apps are able to meet the basic requirements of retaining and engaging users. This study aimed to evaluate participants’ retention and engagement with My Care Hub, a mobile app for DSM. The study employed an explanatory mixed methods design. Participants were people with type 1 or type 2 diabetes who used the health app intervention for 3 weeks. Retention was measured by completion of the postintervention survey. Engagement was measured using system log indices and interviews. Retention and system log indices were presented using descriptive statistics. Transcripts were analyzed using content analysis to develop themes interpreted according to the behavioral intervention technology theory. Of the 50 in iduals enrolled, 42 (84%) adhered to the study protocol. System usage data showed multiple and frequent interactions with the app by most of the enrolled participants (42/50, 84%). Two-thirds of participants who inputted data during the first week returned to use the app after week 1 (36/42, 85%) and week 2 (30/42, 71%) of installation. Most daily used features were tracking of blood glucose (BG 28/42, 68%) and accessing educational information (6/42, 13%). The interview results revealed the app’s potential as a behavior change intervention tool, particularly because it eased participants’ self-care efforts and improved their engagement with DSM activities such as BG monitoring, physical exercise, and healthy eating. Participants suggested additional functionalities such as extended access to historical analytic data, automated data transmission from the BG meter, and periodic update of meals and corresponding nutrients to further enhance engagement with the app. The findings of this short-term intervention study suggested acceptable levels of participant retention and engagement with My Care Hub, indicating that it may be a promising tool for extending DSM support and education beyond the confines of a physical clinic.

Abstract: Evidence-based strategies are needed to curb the growing cases of physical inactivity related morbidities. Delivering holistic care through collaborative shared decision making could boost the effectiveness of physical activity referral schemes (PARS) and foster the quality of care for patients with multimorbidity. A qualitative study involving semi-structured telephone interviews was utilised to gain insights from Australian PARS stakeholders (general practitioners, exercise physiologists, and patients). A pluralistic evaluation approach was employed to explore and integrate participants’ opinions and experiences of PARS and their recommendations were used to develop a model for quality care delivery in PARS initiatives. Five overarching themes: promote, relate, incentivise, communicate, and educate were identified as the ‘PRICE’ for developing effective and functional PARS programmes that foster quality patient care. It was evident that PARS programmes or policies aimed at optimising publicity, encouraging incentives, improving interdisciplinary information sharing and professional relationships between patients and healthcare professionals can transform healthcare delivery and provide top quality PARS care services to patients. Therefore, governments, healthcare systems, and PARS administrators can translate and leverage the insights from this study to optimise the delivery of high quality care to PARS patients.

Abstract: Telehealth has been used extensively in emergency departments to improve healthcare provision. However, its impact on the management of non-critical emergency presentations within rural and remote emergency department settings has not been adequately explored. The objective of this systematic review is to identify how telehealth has been used to assist in the management of non-critical presentations in rural and remote emergency departments and the outcomes. Articles were identified through database searches of CINAHL, Cochrane, MEDLINE (OVID), Informit and SCOPUS, as well as the screening of relevant article reference and citation lists. To determine how telehealth can assist in the management of non-critical emergencies, information was extracted relating to telehealth programme model, the scope of service and participating health professionals. The outcomes of telehealth programmes were determined by analysing the uptake and usage of telehealth, the impact on altering a diagnosis or management plan as well as patient disposition including patient transfer, discharge, local hospital admission and rates of discharge against medical advice. Of the 2532 identified records, 15 were found to match the eligibility criteria and were included in the review. Uptake and usage increased for telehealth programmes predominantly utilised by nursing staff with limited local medical support. Teleconsultation conservatively altered patient diagnosis or management in 18–66% of consultations. Although teleconsultation was associated with increased patient transfer rates, unnecessary transfers were reduced. Simultaneously, an increase in local hospital admission was noted and fewer patients were discharged home. Discharge against medical advice rates were low at 0.9–1.1%. The most widely implemented hub-and-spoke telehealth model could be incorporated into existing referral frameworks. Telehealth programmes may assist in reducing unnecessary patient transfer and secondary overtriage, while increasing the capacity of emergency department staff to diagnose and manage patients locally, which may translate into increased local hospital admission and reduced discharge rates following teleconsultation.

Abstract: Some students struggle through medical school and do not have the confidence to seek help. This pilot study sought to explore the challenges and needs of medical students experiencing academic difficulty. Semi-structured interviews and online surveys were used to collect data from an academic advisor and thirteen medical students who had experienced academic difficulty. Unexpected academic failure and the loss of self-efficacy contributed to students hiding their academic difficulty and avoiding available support systems. Despite the s ling limitations, the findings of this pilot study have value in giving direction to future research. Programs that will change the current attitudes to academic difficulty, normalising access to support and encouraging early intervention, are needed to build the capacity for excellence among these students.
