ABSTRACT
Pesticide active ingredients are frequently detected in the rivers, creeks, wetlands, estuaries, and marine waters of the Great Barrier Reef (GBR) region and are one of the main contributors to poor water quality. Pesticide concentrations detected in the environment through water quality monitoring programs can be compared against estimates of ecologically "safe" concentrations (i.e., water quality guidelines) to assess the potential hazard and risk posed to aquatic ecosystems. Water quality guidelines are also required to estimate the aquatic risk posed by pesticide mixtures, which is used for the Reef 2050 Water Quality Improvement Plan pesticide target. Seventy-four pesticide active ingredients and their degradates are frequently detected in GBR catchment waterways, however many do not have water quality guidelines in the Australian and New Zealand Guidelines for Fresh and Marine Water Quality. The current study derives ecotoxicity threshold values (ETVs) as unendorsed guideline values for active ingredients in two fungicides (4-hydroxychlorothalonil (fungicide degradate) and carbendazim) and two insecticides (dimethoate and methoxyfenozide) that are commonly detected in GBR catchment waterways. The proposed ETVs have been derived using species sensitivity distributions, as recommended in the Australian and New Zealand nationally endorsed method for deriving water quality guidelines for aquatic ecosystem protection. Four ETVs were derived for each chemical with values that should theoretically protect 99, 95, 90 and 80 % of species (i.e., PC99, PC95, PC90, PC80, respectively). The PC99 and PC95 values for 4-hydroxychlorothalonil, carbendazim, dimethoate and methoxyfenozide were 0.49 µg/L and 4 µg/L, 0.029 µg/L and 0.45 µg/L, 0.11 µg/L and 5.8 µg/L and 0.19 µg/L and 2 µg/L, respectively. The ETVs will be used in an ecological hazard and risk assessment across GBR waterways in part two of this study. The ETVs can also be used to assess potential risk across Australia and internationally where monitoring data are available.

BACKGROUND: Gene rearrangements affecting KMT2A are frequent in acute myeloid leukemia (AML) and are often associated with a poor prognosis. KMT2A gene fusions are often detected by chromosome banding analysis and confirmed by fluorescence in situ hybridization. However, small intragenic insertions, termed KMT2A partial tandem duplication (KMT2A-PTD), are particularly challenging to detect using standard molecular and cytogenetic approaches. METHODS: We have validated the use of a custom hybrid-capture-based next-generation sequencing (NGS) panel for comprehensive profiling of AML patients seen at our institution. This NGS panel targets the entire consensus coding DNA sequence of KMT2A. To deduce the presence of a KMT2A-PTD, we used the relative ratio of KMT2A exons coverage. We sought to corroborate the KMT2A-PTD NGS results using (1) multiplex-ligation probe amplification (MLPA) and (2) optical genome mapping (OGM). RESULTS: We analyzed 932 AML cases and identified 41 individuals harboring a KMT2A-PTD. MLPA, NGS, and OGM confirmed the presence of a KMT2A-PTD in 22 of the cases analyzed where orthogonal testing was possible. The two false-positive KMT2A-PTD calls by NGS could be explained by the presence of cryptic structural variants impacting KMT2A and interfering with KMT2A-PTD analysis. OGM revealed the nature of these previously undetected gene rearrangements in KMT2A, while MLPA yielded inconclusive results. MLPA analysis for KMT2A-PTD is limited to exon 4, whereas NGS and OGM resolved KMT2A-PTD sizes and copy number levels. CONCLUSIONS: KMT2A-PTDs are complex gene rearrangements that cannot be fully ascertained using a single genomic platform. MLPA, NGS panels, and OGM are complementary technologies applied in standard-of-care testing for AML patients. MLPA and NGS panels are designed for targeted copy number analysis; however, our results showed that integration of concurrent genomic alterations is needed for accurate KMT2A-PTD identification. Unbalanced chromosomal rearrangements overlapping with KMT2A can interfere with the diagnostic sensitivity and specificity of copy-number-based KMT2A-PTD detection methodologies.
ABSTRACT
The evolution of arborescence in Devonian plants, followed by their architectural radiation in the Carboniferous, is a transition fundamental to Earth-system processes and ecological development. However, this evolutionary transition in trees is based on preserved trunks, of which only a few known specimens possess crowns. We describe Mississippian-aged (Tournaisian) trees with a unique three-dimensional crown morphology from New Brunswick, Canada. The trees were preserved by earthquake-induced, catastrophic burial of lake-margin vegetation. The tree architecture consists of an unbranched, 16-cm-diameter trunk with compound leaves arranged in spirals of â¼13 and compressed into â¼14 cm of vertical trunk length. Compound leaves in the upper â¼0.75 m of the trunk measure >1.75 m in length and preserve alternately arranged secondary laterals beginning at 0.5 m from the trunk; the area below the trunk bears only persistent leaf bases. The principal specimen lacks either apical or basal sections, although an apex is preserved in another. Apically, the leaves become less relaxed toward horizontal and are borne straight at an acute angle at the crown. The compact leaf organization and leaf length created a crown volume of >20-30 m3. This growth strategy likely maximized light interception and reduced resource competition from groundcover. From their growth morphology, canopy size, and volume, we propose that these fossils represent the earliest evidence of arborescent subcanopy-tiering. Moreover, although systematically unresolved, this specimen shows that Early Carboniferous vegetation was more complex than realized, signaling that it was a time of experimental, possibly transitional and varied, growth architectures.

BACKGROUND: Building healthcare service and health professionals' capacity and capability to rapidly translate research evidence into health practice is critical to the effectiveness and sustainability of healthcare systems. This review scoped the literature describing programmes to build knowledge translation capacity and capability in health professionals and healthcare services, and the evidence supporting these. METHODS: This scoping review was undertaken using the Joanna Briggs Institute scoping review methodology. Four research databases (Ovid MEDLINE, CINAHL, Embase, and PsycInfo) were searched using a pre-determined strategy. Eligible studies described a programme implemented in healthcare settings to build health professional or healthcare service knowledge translation capacity and capability. Abstracts and full texts considered for inclusion were screened by two researchers. Data from included papers were extracted using a bespoke tool informed by the scoping review questions. RESULTS: Database searches yielded 10,509 unique citations, of which 136 full texts were reviewed. Thirty-four papers were included, with three additional papers identified on citation searching, resulting in 37 papers describing 34 knowledge translation capability building programmes. Programmes were often multifaceted, comprising a combination of two or more strategies including education, dedicated implementation support roles, strategic research-practice partnerships and collaborations, co-designed knowledge translation capability building programmes, and dedicated funding for knowledge translation. Many programmes utilised experiential and collaborative learning, and targeted either individual, team, organisational, or system levels of impact. Twenty-seven programmes were evaluated formally using one or more data collection methods. Outcomes measured varied significantly and included participant self-reported outcomes, perceived barriers and enablers of knowledge translation, milestone achievement and behaviour change. All papers reported that programme objectives were achieved to varying degrees. CONCLUSIONS: Knowledge translation capacity and capability building programmes in healthcare settings are multifaceted, often include education to facilitate experiential and collaborative learning, and target individual, team, organisational, or supra-organisational levels of impact. Although measured differently across the programmes, the outcomes were positive. The sustainability of programmes and outcomes may be undermined by the lack of long-term funding and inconsistent evaluation. Future research is required to develop evidence-informed frameworks to guide methods and outcome measures for short-, medium- and longer-term programme evaluation at the different structural levels.

What was the educational challenge?Medical student abuse within work-integrated learning (WIL) is well-reported, with negative consequences for wellbeing, motivation, and learning. Conversely, workplace dignity, described as respecting the worth of others and self, has positive impacts on wellbeing, learning, and relationships for WIL students and supervisors. Stakeholders often struggle to articulate what workplace dignity means, and can downplay or do nothing in the face of WIL indignities.What was the solution and how was this implemented?We created an innovative research-informed online learning resource about WIL dignity to improve stakeholders' understandings and help them get the best from WIL placements ensuring these are dignified, safe, and educationally productive. The resource included three topics: (a) workplace dignity and why it matters; (b) upholding dignity; and (c) strengthening dignity.What lessons were learned?We conducted a pilot qualitative evaluation involving 13 semi-structured interviews with students and supervisors to elicit their views and experiences of the resource. Our key findings across three overarching categories were: (1) perceived benefits (motivations to complete the resource; content of the resource; online pedagogies); (2) potential applications of learning (reinforcing existing knowledge; developing new knowledge; promoting reflection; changing workplace practices); and (3) suggested improvements (barriers to resource use; resource content; online pedagogies; timing of resource implementation; embedding the resource in broader learning).What are the next steps?Although we identified numerous perceived benefits, and applications of learning, the findings suggested opportunities for further development, especially improving the resource's social interactivity. We recommend that further resource implementation includes student-educator and student-peer interactivity to maximise learning, and longitudinal evaluation of the resource.

BACKGROUND: Building clinician and organisation-level research translation capacity and capability is fundamental for increasing the implementation of research into health practice and policy and improving health outcomes. Research translation capacity and capability building is particularly crucial in rural and regional settings to address complex problems impacting these socially and economically disadvantaged communities. Programs to build clinicians' research translation capability typically involve training and mentoring. Little is known about the features of and influences on mentorships in the context of training for emerging clinician-researchers working in rural and regional healthcare settings. Research translation mentorships were established as part of the Supporting Translation Research in Rural and Regional settings (STaRR) program developed and delivered in Victoria, Australia from 2020 to 2021. The study sought to address the following research questions: 1) What context-specific types of support do research translation mentors provide to emerging researchers?. 2) How does the mentoring element of a rural research translational training program influence research translation capacity and capability development in rural emerging researchers and mentors, if at all?. 3) How does the mentoring element of the program influence translation capacity and capability at the organisational and regional level, if at all? METHODS: We conducted a qualitative descriptive study. Interviews with individuals involved in the STaRR program took place approximately 12 months after the program and explored participants' experiences of the mentored training. Interviews were undertaken via telephone, audio-recorded, and transcribed. Data were analysed using a team-based five-stage framework approach. RESULTS: Participants included emerging researchers (n = 9), mentors (n = 5), and managers (n = 4), from five health services and two universities. We identified four themes in the interview data: (1) Mentors play an educative role; (2) Mentoring enhanced by a collaborative environment; (3) Organisational challenges can influence mentorships, and (4) Mentorships help develop research networks and collective research and translation capacity. CONCLUSIONS: Mentorships contributed to the development of research translation capabilities. The capabilities were developed through mentors' deepened understanding of the rural and regional healthcare contexts in which their emerging researchers worked, the broadening and strengthening of rural and regional research networks, and building and sharing research translation knowledge and skills.

INTRODUCTION: The timely translation of research into practice and local policy is critical to improving healthcare delivery in rural and regional settings, and remains a concern for researchers, health professionals, health managers and policymakers alike. Successful and sustained research translation does not occur without concerted effort, support and strategies to build research translation capacity and capability. Research capacity comprises individual and organisational capabilities. This study is primarily focused on individual capabilities. Health professionals working in rural and regional settings, where research activity and infrastructure are generally less mature than that seen in metropolitan areas, need additional support and skills to build their capability to engage in translation-focused research. This study aimed to explore rural health research stakeholders' perspectives on capability-building needs for emerging researchers to enable the translation of research into health practice. METHODS: A qualitative description methodology was used to conduct three online focus groups to explore participants' understanding of research translation, and their perceptions of the supports that are needed to build capability for emerging health professional researchers to undertake translation-focused research. Emerging health professional researchers (emerging researchers hereafter) are health professionals who have little or no formal training or experience undertaking research. Data were analysed by a five-stage framework approach. RESULTS: Participants included emerging researchers (n=12), research mentors (n=3) and health managers (n=4) from six rural or regional organisations, including four health services, one university and one primary health network in Victoria, Australia. Participants' conceptualisation of research translation reflected previously documented definitions; that is, research grounded in health practice and characterised by adaptation of existing research evidence to local settings via implementation. Four key themes related to research translation support for rural and regional health researchers were identified: understanding the study and translation context is vital to enacting change; engaging with stakeholders identifies research and translation priorities and suitable approaches; mentor and managerial support assists navigation of research translation activities; and access to clinical and research networks promotes research translation partnerships and collaborations. Participants highlighted the need to identify and train appropriate research mentors and health leaders who can support translation-focused research at the emerging researcher level. The need for training that targets fundamental research translation skills, including systematic processes for engaging stakeholders and collaborative priority setting, and the processes to analyse both the research study and research translation contexts, were also identified as important. CONCLUSION: Given their understanding of the local community and health context, rural and regional health professionals are ideally placed to engage in translation-focused research; however, they require multiple types of research capability development through several levels of influence. This includes support and guidance to ensure their endeavours align with and leverage organisational and regional priorities for research translation. These findings can inform approaches to research capability building through training and resource provision, and organisational infrastructure development and capacity building, to support the rapid translation of research into clinical practice.

3D printing of pharmaceuticals offers a unique opportunity for long-term, sustained drug release profiles for an array of treatment options. Unfortunately, this approach is often limited by physical compounding or processing limitations. Modification of the active drug into a prodrug compound allows for seamless incorporation with advanced manufacturing methods that open the door to production of complex tissue scaffold drug depots. Here we demonstrate this concept using salicylic acids with varied prodrug structures for control of physical and chemical properties. The role of different salicylic acid derivatives (salicylic acid, bromosalicylic allyl ester, iodosalicylic allyl ester) and linker species (allyl salicylate, allyl 2-(allyloxy)benzoate, allyl 2-(((allyloxy)carbonyl)oxy)benzoate) were investigated using thiol-ene cross-linking in digital light processing (DLP) 3D printing to produce porous prodrug tissue scaffolds containing more than 50% salicylic acid by mass. Salicylic acid photopolymer resins were all found to be highly reactive (solidification within 5 s of irradiation at λ = 405 nm), while the cross-linked solids display tunable thermomechanical behaviors with low glass transition temperatures (Tgs) and elastomeric behaviors, with the carbonate species displaying an elastic modulus matching that of adipose tissue (approximately 65 kPa). Drug release profiles were found to be zero order, sustained release based upon hydrolytic degradation of multilayered scaffolds incorporating fluorescent modeling compounds, with release rates tuned through selection of the linker species. Cytocompatibility in 2D and 3D was further demonstrated for all species compared to polycarbonate controls, as well as salicylic acid-containing composites (physical incorporation), over a 2-week period using murine fibroblasts. The use of drugs as the matrix material for solid prodrug tissue scaffolds opens the door to novel therapeutic strategies, longer sustained release profiles, and even reduced complications for advanced medicine.

The intestine is the primary colonisation site for carbapenem-resistant Enterobacteriaceae (CRE) and serves as a reservoir of CRE that cause invasive infections (e.g. bloodstream infections). Broad-spectrum antibiotics disrupt colonisation resistance mediated by the gut microbiota, promoting the expansion of CRE within the intestine. Here, we show that antibiotic-induced reduction of gut microbial populations leads to an enrichment of nutrients and depletion of inhibitory metabolites, which enhances CRE growth. Antibiotics decrease the abundance of gut commensals (including Bifidobacteriaceae and Bacteroidales) in ex vivo cultures of human faecal microbiota; this is accompanied by depletion of microbial metabolites and enrichment of nutrients. We measure the nutrient utilisation abilities, nutrient preferences, and metabolite inhibition susceptibilities of several CRE strains. We find that CRE can use the nutrients (enriched after antibiotic treatment) as carbon and nitrogen sources for growth. These nutrients also increase in faeces from antibiotic-treated mice and decrease following intestinal colonisation with carbapenem-resistant Escherichia coli. Furthermore, certain microbial metabolites (depleted upon antibiotic treatment) inhibit CRE growth. Our results show that killing gut commensals with antibiotics facilitates CRE colonisation by enriching nutrients and depleting inhibitory microbial metabolites.

The human gut microbiota can restrict the growth of pathogens to prevent them from colonizing the intestine ('colonization resistance'). However, antibiotic treatment can kill members of the gut microbiota ('gut commensals') and reduce competition for nutrients, making these nutrients available to support the growth of pathogens. This disturbance can lead to the growth and expansion of pathogens within the intestine (including antibiotic-resistant pathogens), where these pathogens can exploit the absence of competitors and the nutrient-enriched gut environment. In this review, we discuss nutrient competition between the gut microbiota and pathogens. We also provide an overview of how nutrient competition can be harnessed to support the design of next-generation microbiome therapeutics to restrict the growth of pathogens and prevent the development of invasive infections.

BACKGROUND: Research capacity and capability of rural health professionals is essential to the delivery of evidence-based care and for informing strategies to address rural health inequities. Effective implementation of research education and training is fundamental to building rural health professional research capacity and capability. A lack of overarching guidance to inform the delivery of research education and training in rural health services can contribute to gaps in capacity-building approaches. The aim of this study was to identify characteristics of the design and implementation of current research training for rural health professionals in Victoria, Australia, to inform a future model for rural health professional research capacity and capability building. METHODS: A qualitative descriptive study was undertaken. Key informants, with extensive knowledge of research education and training in rural health services in Victoria, were invited to participate in semi-structured telephone interviews via snowballing recruitment methods. Interview transcripts were analysed inductively, with themes and codes mapped to the domains of the Consolidated Framework for Implementation Research. RESULTS: Of the 40 key informants approached, 20 agreed to participate including 11 regional health service managers, five rural health academics and four university managers. Participants suggested that research training varied in quality and relevance to rural health professionals. Training costs and lack of tailoring to the rural context were key barriers, whereas experiential learning and flexible modes of delivery enabled training uptake. Health service and government policies, structures, and processes both enabled or stifled implementation opportunities, with rural health professional networks from different regions offering capacity for research training development, and government departmental structures hampering training coordination. Tension between research activities and clinical practice, and health professional knowledge and beliefs, shaped the delivery of training programs. Strategically planned and evaluated research training programs and education via co-design with rural health professionals and use of research champions were strongly recommended by participants. CONCLUSIONS: To optimise research training for rural health professionals and increase the quality and quantity of relevant rural health research, a systematically planned, implemented, and resourced region-wide research training model is required.

INTRODUCTION: Allied health assistants are support staff who assist medical imaging professionals in their clinical and non-clinical role. Assistants can improve efficiency of medical imaging services; however, little is known about the specific tasks they perform. METHOD: A two-phase explanatory, sequential mixed-methods study design comprising a time motion survey and qualitative interviews was conducted across three health services in Victoria, Australia. Participants were medical imaging assistants supporting medical imaging professionals. Participants recorded tasks completed on a time motion proforma across two working days. Time spent on tasks was categorised into patient related and non-patient related tasks. Semi-structured interviews were conducted to explore assistants' perspectives about tasks, their roles and any responsibilities. Time motion data was descriptively analysed. Qualitative data were audiotaped, transcribed verbatim and analysed using the framework analysis method. Quantitative and qualitative findings were integrated using data triangulation. RESULTS: Four medical imaging assistants participated, providing 4170 min of time motion data and 138 min of interview data. Integration of time motion and interview data revealed the medical imaging assistant role is predominantly non-patient facing; autonomous and critical to workflow; diverse and requires flexibility; has the potential to expand into a more patient-facing role. CONCLUSIONS: Medical imaging assistants make significant contributions to workflow management. Their role is predominantly non-patient facing but there appear opportunities for the clinical role to expand. Realizing these opportunities will require careful consideration of the challenges and benefits of extending their scope of practice.

Memory consolidation is the process in which memory traces are strengthened over time for later retrieval. Although some theories hold that consolidation can only occur during sleep, accumulating evidence suggests that brief periods of wakeful rest may also facilitate consolidation. Interestingly, however, Varma and colleagues reported that a demanding 2-back task following encoding produced a similar performance to a wakeful reset condition. We tested whether participants' recall would be best following a wakeful rest condition as compared to other distractor conditions, consistent with the extant wakeful rest literature, or whether we would replicate the finding by Varma and colleagues such that participants' memory benefitted from both a rest and a 2-back task following encoding. Across two experiments, we used similar (Experiment 1) and the same (Experiment 2) encoding material as used the one by Varma and colleagues, employed a wakeful rest condition adapted for online testing, and compared participants' recall across post-encoding conditions. In the first experiment, we used a between-subjects design and compared participants' cued recall performance following a period of wakeful rest, a 2-back task, or a rest + sounds condition. The second experiment more closely replicated the experimental design used by Varma and colleagues using a within-subjects manipulation. Ultimately, our findings more consistently aligned with the canonical wakeful rest finding, such that recall was better following the rest condition than all other post-encoding conditions. These results support the notion that wakeful rest may allow for consolidation by protecting recently encoded information from interference, thereby improving memory performance.
ABSTRACT
BACKGROUND: Allied health assistants (AHAs) are support staff who complete patient and non-patient related tasks under the delegation of an allied health professional. Delegating patient related tasks to AHAs can benefit patients and allied health professionals. However, it is unclear whether the AHA workforce is utilised optimally in the provision of patient care. The purpose of this study was to determine the proportion of time AHAs spend on patient related tasks during their working day and any differences across level of AHA experience, clinical setting, and profession delegating the task. METHODS: A time motion study was conducted using a self-report, task predominance work sampling method. AHAs were recruited from four publicly-funded health organisations in Victoria, Australia. AHAs worked with dietitians, occupational therapists, physiotherapists, podiatrists, social workers, speech pathologists, psychologists, and exercise physiologists. The primary outcome was quantity of time spent by AHAs on individual task-categories. Tasks were grouped into two main categories: patient or non-patient related activities. Data were collected from July 2020 to May 2021 using an activity capture proforma specifically designed for this study. Logistic mixed-models were used to investigate the extent to which level of experience, setting, and delegating profession were associated with time spent on patient related tasks. RESULTS: Data from 51 AHAs showed that AHAs spent more time on patient related tasks (293 min/day, 64%) than non-patient related tasks (167 min/day, 36%). Time spent in community settings had lower odds of being delegated to patient related tasks than time in the acute hospital setting (OR 0.44, 95%CI 0.28 to 0.69, P < 0.001). Time delegated by exercise physiologists and dietitians was more likely to involve patient related tasks than time delegated by physiotherapists (exercise physiology: OR 3.77, 95% 1.90 to 7.70, P < 0.001; dietetics: OR 2.60, 95%CI 1.40 to 1.90, P = 0.003). Time delegated by other professions (e.g. podiatry, psychology) had lower odds of involving patient related tasks than physiotherapy (OR 0.37, 95%CI 0.16 to 0.85, P = 0.02). CONCLUSION: AHAs may be underutilised in community settings, and by podiatrists and psychologists. These areas may be targeted to understand appropriateness of task delegation to optimise AHAs' role in providing patient care.

AIMS: This commentary aims to describe a case of how meaningful co-design between rural health service leaders and a health service-embedded research unit can identify emerging research priorities and optimise translation. CONTEXT: The challenges facing rural health services are unique, and the important role of health service leaders in the research response is increasingly recognised. Poorly-designed research can contribute to research waste through reduced applicability of results to rural communities, and an opportunity exists to increase research co-designed with rural health services through the involvement of research users during study planning. APPROACH: In early 2020, leaders at a rural Victorian health service approached the embedded health service research unit to request research be conducted on an emerging issue: rural staff well-being in the face of the COVID-19 pandemic. This was based on their concern regarding the lack of available COVID-19-specific evidence to inform organisational policy. In collaboration with the rural health service executive, a translation-focused study of staff well-being with nine rural Victorian health services was developed. Key co-design activities of the project included involving research end-users as study investigators and conducting formal stakeholder engagement regarding study design and outcomes. CONCLUSION: Meaningful co-design of research with health services is a multifaceted process that can assist researchers and end-users alike in identifying and responding to emerging health issues. In the rural setting where there is a vital need for impactful health research, we recommend that researchers should consider employing co-design processes in order to minimise research waste and optimise the translatability of research findings.

General community occupational therapists (OTs) work with clients experiencing chronic and complex conditions, some living with one or more comorbid common mental health issues (such as anxiety, depression or distress). This study aimed to describe the perspectives of general community OTs of their engagement with clients experiencing mental health issues; their perceptions of the implementation of routine screening in their practice, and the knowledge, skills and support they need to identify and support their clients' mental health needs. Six focus groups were undertaken with general community OTs (n = 21) from three Australian health services in rural, regional and metropolitan settings, between December 2020 and January 2021. Data were analysed using a team-based framework approach. Three key themes were identified: (1) OTs' experiences working with people with mental health issues; (2) impacts of engaging with clients experiencing mental health issues on OTs; and (3) implementing routine mental health screening in general community OT practice. The latter had two sub-themes: (i) identified considerations and (ii) education and system-level support needs. General community OTs frequently work with clients with mental health issues. These experiences impact their practice in multiple ways. This study highlights opportunities for integrating routine mental health screening into general community OT practice and identifies the system and educational development required to support this enhancement to practice. Supporting general community OTs to routinely screen for mental health issues will enhance collaborative client-centred care. Our findings may also have implications for other community-based health professionals and services, particularly those delivered in clients' homes.

Allied health assistants (AHAs) are important members of the health workforce and key to meeting population health needs. Previous studies exploring the role and utility of AHAs from multiple stakeholder perspectives suggest AHAs remain poorly utilised in many healthcare settings. This qualitative study explores the experiences and perspectives of AHAs working in healthcare settings to determine the contextual factors influencing their role, and mechanisms to maximise their utility. We conducted semi-structured interviews using purposive sampling with 21 AHAs, from one regional and three metropolitan health services in Australia, between February and July 2021. We used a team-based framework approach to analyse the data. Four major themes were identified: 1) AHAs' interpersonal relationships, 2), clarity and recognition of AHA roles and role boundaries, 3) AHAs accessing education and professional development, and 4) the professional identity of the AHA workforce. Underpinning each of these themes were relationships between AHAs and other healthcare professionals, their patients, health services, and the wider AHA workforce. This study may inform initiatives to optimise the utility of AHAs and increase their role in, and impact on, patient care. Such initiatives include the development and implementation of guidelines and competencies to enhance the clarity of AHAs' scope of practice, the establishment of standardised educational pathways for AHAs, and increased engagement with the AHA workforce to make decisions about their scope of practice. These initiatives may precede strategies to advance the AHA career structure.

Coastal ecosystems such as those in the Great Barrier Reef (GBR) lagoon, are exposed to stressors in flood plumes including low light (caused by increased turbidity) and agricultural pesticides. Photosystem II (PSII)-inhibiting herbicides are the most frequently detected pesticides in the GBR lagoon, but it is not clear how their toxicity to phototrophic species depends on light availability. This study investigated the individual and combined effects of PSII-inhibiting herbicide, diuron, and reduced light intensity (as a proxy for increased turbidity) on the marine diatom, Phaeodactylum tricornutum. Effective quantum yield (EQY) and cell density were measured to calculate responses relative to the controls over 72-h, in tests with varying stressor intensities. Individually, diuron concentrations (0.1-3 µg l-1) were not high enough to significantly reduce growth (cell density), but led to decreased EQY; while, low light generally led to increased EQY, but only reduced growth at the lowest tested light intensity (5 µmol photons m-2 s-1) after 48-hours. P. tricornutum was less affected by diuron when combined with low light scenarios, with increased EQY (up to 163% of the controls) that was likely due to increased electron transport per photon, despite lesser available photons at this low light intensity. In contrast, growth was completely inhibited relative to the controls when algae were simultaneously exposed to the highest stressor levels (3 µg l-1 diuron and 5 µmol photons m-2 s-1). This study highlights the importance of measuring more than one biological response variable to capture the combined effects of multiple stressors. Management of water quality stressors should consider combined impacts rather than just the impacts of individual stressors alone. Reducing suspended sediment and diuron concentrations in marine waters can decrease harmful effects and bring synergistic benefits to water quality.

BACKGROUND: Research capacity building (RCB) initiatives have gained steady momentum in health settings across the globe to reduce the gap between research evidence and health practice and policy. RCB strategies are typically multidimensional, comprising several initiatives targeted at different levels within health organisations. Research education and training is a mainstay strategy targeted at the individual level and yet, the evidence for research education in health settings is unclear. This review scopes the literature on research education programs for nurses and allied health professionals, delivered and evaluated in healthcare settings in high-income countries. METHODS: The review was conducted systematically in accordance with the Joanna Briggs Institute scoping review methodology. Eleven academic databases and numerous grey literature platforms were searched. Data were extracted from the included full texts in accordance with the aims of the scoping review. A narrative approach was used to synthesise findings. Program characteristics, approaches to program evaluation and the outcomes reported were extracted and summarised. RESULTS: Database searches for peer-reviewed and grey literature yielded 12,457 unique records. Following abstract and title screening, 207 full texts were reviewed. Of these, 60 records were included. Nine additional records were identified on forward and backward citation searching for the included records, resulting in a total of 69 papers describing 68 research education programs. Research education programs were implemented in fourteen different high-income countries over five decades. Programs were multifaceted, often encompassed experiential learning, with half including a mentoring component. Outcome measures largely reflected lower levels of Barr and colleagues' modified Kirkpatrick educational outcomes typology (e.g., satisfaction, improved research knowledge and confidence), with few evaluated objectively using traditional research milestones (e.g., protocol completion, manuscript preparation, poster, conference presentation). Few programs were evaluated using organisational and practice outcomes. Overall, evaluation methods were poorly described. CONCLUSION: Research education remains a key strategy to build research capacity for nurses and allied health professionals working in healthcare settings. Evaluation of research education programs needs to be rigorous and, although targeted at the individual, must consider longer-term and broader organisation-level outcomes and impacts. Examining this is critical to improving clinician-led health research and the translation of research into clinical practice.

INTRODUCTION AND OBJECTIVE: Building rural health workforce research capacity is critical to addressing rural health inequalities. Research training is a mainstay research capacity building strategy. This paper describes the delivery and evaluation of a research training program for rural and regional allied health professions (AHPs). DESIGN: A mentored research training program was delivered to AHPs employed public health services in rural and regional Victoria, Australia. The program was evaluated using the Evidence-Based Practice Knowledge Attitudes and Practice (EBP-KAP) tool at baseline and 3 months post-training. Semi-structured interviews undertaken at 3 and 16 months post-training explored participants' perspectives of the training, their development and application of EBP and research skills. Survey data were analysed descriptively, and interview data were analysed using a framework approach. FINDINGS: Thirty-four individuals from 14 organisations attended the first workshop and 31 attended the second. Thirty-one participants completed the survey at baseline and nine at 3 months post-training. Sixteen interviews were undertaken with 11 participants, five participating at both time points. Participants had positive EBP attitudes at both time points. Overall, participants' knowledge and incorporation of EBP into their practice, and retrieval of evidence was unchanged 3 months post-training. Themes identified in the interview data were as follows: (1) individual research capacity enhanced through supported practice, (2) organisational factors influence individuals' progression of research and (3) individual contributions towards research capacity within the organisation. CONCLUSION: A mentored rural research training program promoted the application of EBP skills at the individual level and contributed to organisational research capacity.
