Using design thinking to create and implement a 3D digital library of anatomical specimens.

Design thinking (DT) is a five-stage process (empathize, define, ideate, prototype, and test) that guides the creation of user-centered solutions to complex problems. DT is in common use outside of science but has rarely been applied to anatomical education. The use of DT in this study identified the need for flexible access to anatomical specimens outside of the anatomy laboratory and guided the creation of a digital library of three-dimensional (3D) anatomical specimens (3D Anatomy Viewer). To test whether the resource was fit for purpose, a mixed-methods student evaluation was undertaken. Student surveys (n = 46) were employed using the system usability scale (SUS) and an unvalidated acceptability questionnaire. These verified that 3D Anatomy Viewer was usable (SUS of 72%) and acceptable (agreement range of 77%-93% on all Likert-type survey statements, Cronbach's alpha = 0.929). Supplementary interviews (n = 5) were analyzed through content analysis and revealed three main themes: (1) a credible online supplementary learning resource; (2) learning anatomy with 3D realism and interactivity; (3) user recommendations for expanding the number of anatomical models, test questions, and gamification elements. These data demonstrate that a DT framework can be successfully applied to anatomical education for creation of a practical learning resource. Anatomy educators should consider employing a DT framework where student-centered solutions to learner needs are required.

Australian physiotherapists attitudes, perceptions, and behaviours towards psychosocial screening tools: a qualitative interpretive description study.

PURPOSE: Psychosocial factors are a barrier to recovery for people with musculoskeletal pain and psychosocial screening tools are consistently recommended by best practice guidelines to assist in identification. However, many physiotherapists do not use these tools. Presently, the perspectives on psychosocial screening tools of Australian physiotherapists are unknown. Exploration of these factors may create targets for increased uptake. The purpose of this paper is to qualitatively explore Australian physiotherapists' attitudes, perceptions, and behaviours towards psychosocial screening tools for musculoskeletal pain conditions. MATERIALS AND METHODS: An Interpretive description qualitative study design was employed. Seventeen Australian physiotherapists were interviewed about their attitudes, perceptions, and behaviours towards psychosocial screening tools. Interviews were transcribed verbatim and analysed according to interpretive description. RESULTS: Analysis highlighted three major themes: (1) understanding the patient through psychosocial screening, (2) confidence and competence with psychosocial factors, and (3) factors outside of my control influence screening. CONCLUSIONS: This study presents a deeper understanding of Australian physiotherapists' diverse attitudes and practices regarding psychosocial screening tools. The research highlights not only the variability in perspectives towards the relevance of psychosocial factors in patient assessments, but also the influence of external elements such as patient demographics and clinic culture on the utilization of these screening methods.

Australian physiotherapists' varying attitudes and limited understanding of the impact of psychosocial factors may hinder the use of recommended psychosocial screening.Concerns about scope of practice, tool appropriateness for different patients, and clinic culture further challenge the integration of psychosocial assessments.The findings from this study indicate the need to provide more education to Australian physiotherapists on the importance and use of psychosocial risk factor screening, as part of clinical care standards and best practice guidelines in the management of patients, with musculoskeletal pain conditions.The findings from this study can support the creation of targeted training/innovations to improve the uptake of screening tools in Australian musculoskeletal clinical practice, to improve the care of patients with musculoskeletal pain conditions.

Development of a pharmaceutical science systematic review process using a semi-automated machine learning tool: Intravenous drug compatibility in the neonatal intensive care setting.

Our objective was to establish and test a machine learning-based screening process that would be applicable to systematic reviews in pharmaceutical sciences. We used the SPIDER (Sample, Phenomenon of Interest, Design, Evaluation, Research type) model, a broad search strategy, and a machine learning tool (Research Screener) to identify relevant references related to y-site compatibility of 95 intravenous drugs used in neonatal intensive care settings. Two independent reviewers conducted pilot studies, including manual screening and evaluation of Research Screener, and used the kappa-coefficient for inter-reviewer reliability. After initial deduplication of the search strategy results, 27 597 references were available for screening. Research Screener excluded 1735 references, including 451 duplicate titles and 1269 reports with no abstract/title, which were manually screened. The remainder (25 862) were subject to the machine learning screening process. All eligible articles for the systematic review were extracted from <10% of the references available for screening. Moderate inter-reviewer reliability was achieved, with kappa-coefficient ≥0.75. Overall, 324 references were subject to full-text reading and 118 were deemed relevant for the systematic review. Our study showed that a broad search strategy to optimize the literature captured for systematic reviews can be efficiently screened by the semi-automated machine learning tool, Research Screener.

A systematic search and narrative review of Aboriginal and Torres Strait Islander women and men pelvic health care: demonstrated need for improvement.

Warning:This article contains terms, descriptions and opinions that may be culturally sensitive for Aboriginal and Torres Strait Islander peoples. BACKGROUND: Pelvic health conditions among Aboriginal and Torres Strait Islander women and men are under-recognised and under-reported despite indication of the significant burden of these conditions. Access to effective management provided in a culturally safe manner appears lacking. The study aims were to: (1) summarise the burden of pelvic health conditions among Aboriginal and Torres Strait Islander peoples; (2) explore barriers and enablers to Aboriginal and Torres Strait Islander peoples accessing pelvic healthcare services; and (3) provide considerations on how to implement culturally safe pelvic healthcare services for Aboriginal and Torres Strait Islander peoples. METHODS: This study involved a systematic literature search informing a narrative review. RESULTS: Fourteen specific articles were identified. Burden related to pelvic health conditions was identified for both women and men, noting high likelihood of under-reporting. Barriers to effective culturally safe treatment included racism, shame and stigma associated with women's and men's business, lack of culturally safe services and geographical distance. Enablers included building trust with local communities, using yarning principles and codesign of pelvic health services with Aboriginal health workers and services. Strategies to improve pelvic health care for Aboriginal and Torres Strait Islander peoples were described at the systems, health service and clinician levels. CONCLUSION: Efforts are needed to improve the diagnosis and management of pelvic health conditions for Aboriginal and Torres Strait Islander peoples. Actions are required to engage with local Aboriginal Community Controlled Aboriginal Community Controlled Health Organisations, professionals overseeing service provision and healthcare providers to address the burden of these conditions among Aboriginal and Torres Strait Islander peoples.

Protocol for a systematic review of reviews on training primary care providers in dermoscopy to detect skin cancers.

INTRODUCTION: Globally, incidence, prevalence and mortality rates of skin cancers are escalating. Earlier detection by well-trained primary care providers in techniques such as dermoscopy could reduce unnecessary referrals and improve longer term outcomes. A review of reviews is planned to compare and contrast the conduct, quality, findings and conclusions of multiple systematic and scoping reviews addressing the effectiveness of training primary care providers in dermoscopy, which will provide a critique and synthesis of the current body of review evidence. METHODS AND ANALYSIS: Four databases (Cochrane, CINAHL, EMBASE and MEDLINE Complete) will be comprehensively searched from database inception to identify published, peer-reviewed English-language articles describing scoping and systematic reviews of the effectiveness of training primary care providers in the use of dermoscopy to detect skin cancers. Two researchers will independently conduct the searches and screen the results for potentially eligible studies using 'Research Screener' (a semi-automated machine learning tool). Backwards and forwards citation tracing will be conducted to supplement the search. A narrative summary of included reviews will be conducted. Study characteristics, for example, population; type of educational programme, including content, delivery method, duration and assessment; and outcomes for dermoscopy will be extracted into a standardised table. Data extraction will be checked by the second reviewer. Methodological quality will be evaluated by two reviewers independently using the Critical Appraisal Tool for Health Promotion and Prevention Reviews. Results of the assessments will be considered by the two reviewers and any discrepancies will be resolved by team consensus. ETHICS AND DISSEMINATION: Ethics approval is not required to conduct the planned systematic review of peer-reviewed, published articles because the research does not involve human participants. Findings will be published in a peer-reviewed journal, presented at leading public health, cancer and primary care conferences, and disseminated via website postings and social media channels. PROSPERO REGISTRATION NUMBER: CRD42023396276.

Energetic landscape of polycystin channel gating.

Members of the polycystin family (PKD2 and PKD2L1) of transient receptor potential (TRP) channels conduct Ca2+ and depolarizing monovalent cations. Variants in PKD2 cause autosomal dominant polycystic kidney disease (ADPKD) in humans, whereas loss of PKD2L1 expression causes seizure susceptibility in mice. Understanding structural and functional regulation of these channels will provide the basis for interpreting their molecular dysregulation in disease states. However, the complete structures of polycystins are unresolved, as are the conformational changes regulating their conductive states. To provide a holistic understanding of the polycystin gating cycle, we use computational prediction tools to model missing PKD2L1 structural motifs and evaluate more than 150 mutations in an unbiased mutagenic functional screen of the entire pore module. Our results provide an energetic landscape of the polycystin pore, which enumerates gating sensitive sites and interactions required for opening, inactivation, and subsequent desensitization. These findings identify the external pore helices and specific cross-domain interactions as critical structural regulators controlling the polycystin ion channel conductive and nonconductive states.

An Exploration of the Influence of Non-Biomechanical Factors on Lifting-Related LBP.

Objective: The primary objective was to compare non-biomechanical factors between manual workers with and without a history of LBP related to lifting. A secondary objective was to investigate associations between the change in pain intensity during repeated lifting (termed pain ramp) and non-biomechanical factors tested in the LBP group. Methods: Manual workers currently in lifting occupations with and without a history of lifting-related LBP were recruited (21 LBP and 20 noLBP) and took part in a repeated (100) lift task. A series of non-biomechanical factors, including psychological, work-related, lifestyle, whole health and psychophysical factors, were collected. Psychophysical factors (pressure pain thresholds (PPTs) and fatigue) were also measured at different time points. Associations between pain ramp during lifting and non-biomechanical factors were investigated with linear regression. Results: The LBP group reported worse perceived sleep quality, more musculoskeletal pain sites other than LBP and greater symptoms related to gastrointestinal complaints and pseudo-neurology compared to the group with no history of LBP. The group with LBP were also slightly more worried about the lifting task and felt more fatigued at the end of the lifting task. The feeling of fatigue during lifting was positively associated with pain ramp in the LBP group. Anxiety and gastrointestinal complaints were weakly negatively associated with pain ramp during lifting. Conclusions: The group differences of poorer perceived sleep, greater non-specific health complaints, slightly more worry about the lifting task and more perceived fatigue in the LBP group highlight the complex and multi-factorial nature of LBP related to lifting. The feeling of fatigue was positively associated with pain ramp in the LBP group, suggesting a close relationship with pain and fatigue during lifting that requires further exploration.

Footstrike angle cut-off values to classify footstrike pattern in runners.

Footstrike angle (FSA) has been widely used to classify footstrike pattern (FSP). However, inconsistent FSA cut-off values were adopted in previous studies. This study aimed to validate the FSA cut-off values in runners. Stride index, the gold standard to determine FSP, and FSA were obtained when 15 experienced runners, 14 novice runners and 14 untrained individuals performed 3-min run on an instrumented treadmill at their preferred running speeds in habitual, rearfoot, midfoot and forefoot strike patterns. According to the receiver operating characteristic curve associated with the Youden index, the optimal FSA cut-off values were -0.8° (i.e., cut-off angle for forefoot strike) -7.4° (i.e., cut-off angle for rearfoot strike) for runners. We observed minor differences in the FSA cut-off values across runners with various running experience and a wider cut-off range for midfoot strikers when a modified strike index was utilized. This validation study established cut-off footstrike angles for runners' FSP classification.

Questionnaires Measuring Physical Activity in Clinical Pediatric Populations: A Systematic Review.

PURPOSE: Regular physical activity (PA) is a cornerstone therapy for many childhood chronic health conditions, and questionnaires offer a simple method for monitoring PA and identifying children who do not meet clinical practice guidelines. The purpose of this systematic review is to determine which questionnaires are most efficacious for assessing PA in children with chronic health conditions. METHODS: Systematic literature searches were conducted through ProQuest, MEDLINE, Scopus, and SPORTDiscus from January 2010 to August 2020 to identify studies that measured PA with a validated questionnaire in children and adolescents aged 3-18 years old with chronic health conditions. In eligible studies, the validity and reliability of questionnaires were identified, and the modified COnsensus-based Standards for the selection of health status Measurement INstruments checklist and Grading of Recommendations, Assessment, Development, and Evaluations were used to assess the quality and strength of evidence and risk of bias. RESULTS: Four thousand four hundred and seventy-eight references were extracted, and 10 articles were included for review. From 10 eligible studies, 6 questionnaires were identified, none of which adequately measure PA in clinical pediatric populations. CONCLUSION: Questionnaires to adequately measure PA in children with chronic conditions are lacking. This compromises the identification of those who do not meet PA guidelines, limiting the opportunity to identify and address factors contributing to low PA levels.

Targeting the tamoxifen receptor within sodium channels to block osteoarthritic pain.

Voltage-gated sodium channels (NaV) in nociceptive neurons initiate action potentials required for transmission of aberrant painful stimuli observed in osteoarthritis (OA). Targeting NaV subtypes with drugs to produce analgesic effects for OA pain management is a developing therapeutic area. Previously, we determined the receptor site for the tamoxifen analog N-desmethyltamoxifen (ND-Tam) within a prokaryotic NaV. Here, we report the pharmacology of ND-Tam against eukaryotic NaVs natively expressed in nociceptive neurons. ND-Tam and analogs occupy two conserved intracellular receptor sites in domains II and IV of NaV1.7 to block ion entry using a "bind and plug" mechanism. We find that ND-Tam inhibition of the sodium current is state dependent, conferring a potent frequency- and voltage-dependent block of hyperexcitable nociceptive neuron action potentials implicated in OA pain. When evaluated using a mouse OA pain model, ND-Tam has long-lasting efficacy, which supports the potential of repurposing ND-Tam analogs as NaV antagonists for OA pain management.
