- Description: Background: Previous studies have examined the relationship between external load and creatine-kinase (CK) response at the team level. This study aimed to build individualized CK prediction models for elite youth national team soccer players. Hypothesis: The CK response of youth soccer players can be categorized as being sensitive to micromovements (MM), high-velocity (HV) parameters, or the combination of both, measured during training sessions and matches. Study Design: Prospective cohort study. Level of Evidence: Level 4. Methods: A total of 25 U16-U17 youth national team soccer players were monitored during training sessions and matches using global positioning system (GPS) units. Individual CK values were measured every morning from whole blood. The data set consisted of 57 ± 17 individual datapoints per player. Individual prediction models were used to examine the relationship between external load and consecutive CK changes. Numerous models were built for each player using MM, HV parameters, or the combination of both. The performance of the models was described by the R2 and the root mean square error (RMSE, U/l for CK values). Results: The MM models were superior for 8 players (R2 = 0.68; RMSE = 113 U/l), followed by HV (8 players; R2 = 0.69; RMSE = 88 U/l) and the combined models (2 players; R2 = 0.64; RMSE = 141 U/l). For the remaining 7 players, the R2 of the models was <0.5. The recovery time between efforts was more important in the HV model. Conclusion: Players could be categorized on sensitivity to MM, HV movements, or the combination of both. Clinical Relevance: These findings can be used to individualize postmatch recovery strategies and to optimize weekly training periodization to maximize match performance. © 2022 The Author(s).

- Description: Objective: To characterise paediatric poisoning presentations to EDs and determine if the advent of the COVID-19 pandemic was associated with increased intentional paediatric poisoning presentations. Methods: We performed a retrospective analysis of paediatric poisoning presentations to three EDs (two regional and one metropolitan). Simple and multiple logistic regression analysis were performed to determine the association between COVID-19 and intentional poisoning events. In addition, we calculated the frequency with which patients reported various psychosocial risk factors as being an implicating factor in engaging in an intentional poisoning event. Results: A total of 860 poisoning events met inclusion criteria during the study period (January 2018–October 2021), with 501 being intentional, and 359 unintentional. There was an increased proportion of intentional poisoning presentations during the COVID-19 pandemic (261 intentional and 218 unintentional in the pre-COVID-19 period vs 241 intentional and 140 unintentional during the COVID-19 period). In addition, we found a statistically significant association between intentional poisoning presentations and an initial COVID-19 lockdown (adjusted odds ratio 26.32, P < 0.05). ‘The COVID-19 lockdown’ or ‘COVID-19’ was reported to be implicating factor for psychological stress in patients who presented with intentional poisonings during the COVID-19 pandemic. Conclusions: Intentional paediatric poisoning presentations increased during the COVID-19 pandemic in our study population. These results may support an emerging body of evidence that the psychological strain of COVID-19 disproportionately impacts adolescent females. © 2023 The Authors.

- Description: Background: Complementary and Alternative Medicine (CAM) interventions may prove to be an attractive option for the treatment of depression. The aim of this scientometric analysis is to determine the global scientific output of research regarding managing depression with CAM and identify the hotspots and frontiers within this theme. Methods: Publications regarding the utilization of CAM for treating depression were collected from the Web of Science Core Collection from 1993 to 2022, and analyzed and visualized by Bibliometrix R-package, VOSviewer, and CiteSpace. Results: A total of 1,710 publications were acquired. The number of annual publications showed an overall rapid upward trend, with the figure peaking at 179 in 2021. The USA was the leading research center. Totally 2,323 distinct institutions involving 7,638 scholars contributed to the research theme. However, most of the cooperation was limited to within the same country, institution or research team. The Journal of Alternative and Complementary Medicine was the most productive periodical. The CAM therapies of most interest to researchers were acupuncture and body–mind techniques, such as yoga, meditation and mindfulness. Systematic review and meta-analysis are commonly used methods. “Inflammation,” “rating scale” and “psychological stress” were identified as the most studied trend topics recently. Conclusion: Managing depression with evidence-based CAM treatment is gaining attention globally. Body–mind techniques and acupuncture are growing research hotspots or emerging trending topics. Future studies are predicted to potentially investigate the possible mechanisms of action underlying CAM treatments in reducing depression in terms of modulation of psychological stress and inflammation levels. Cross-countries/institutes/team research collaborations should be encouraged and further enhanced. Copyright © 2023 Zhao, Xu, Zheng, Conduit, Xu, Yue, Wang, Wang, Li, Li, Zhang, Fu and Kennedy.

- Description: Our perception of time plays a critical role in nearly all daily activities and especially in sports. There are no studies that have investigated and compared time perception during exercise in young and older adults. Thus, this study aimed to compare the effects of exercise on time perception between younger and older adult populations. Thirty-three recreationally active participants were recruited and assigned to either the younger (university students, 9 males and 10 females) or older adults (>60 years, 8 males and 6 females). All participants completed four exercise conditions over two sessions on separate days: approximately 30-seconds of knee extensors 100%, 60% and 10% of maximum voluntary isometric contraction (MVIC), and control (no contractions). Prospective time perception was estimated (at 5-, 10-, 20-, and 30-seconds) at the beginning of each session and while performing the exercise. A main effect for condition (p < 0.001, d = 1.06) with subsequent post-hoc tests indicated participants significantly underestimated (estimated time was shorter than chronological time) time in all three exercise conditions compared to the control. There were no significant age group differences. In conclusion, exercise underestimated time estimates regardless of intensity or age. This questions the postulated intensity-dependent relationship between exercise and time perception. While older adults were expected to be less accurate in their time estimates, they may have been able to adopt alternative strategies for agerelated changes in their internal clock, resulting in no significant age group differences. © 2023, Journal of Sport Science and Medicine.

- Description: Objective(s): The aim of this paper was to report on qualitative survey responses provided by older Australian adults regarding their preferences for Internet-based services and content. Methods: Two qualitative questions (‘What type of Internet-based mental health and well-being (1) services, and (2) content would be of most interest to you?’) from a broader survey investigating the mental and physical health of older Australians were thematically analysed for commonly occurring themes. Eighty-nine participants aged 65 years or older (mean age = 71 years, SD = 5.30) responded to at least one qualitative question. Participants were primarily female (60%, n = 53), born in Australia (65%, n = 58), in a relationship (58%, n = 52), living in the community (79%, n = 70) and relatively well educated, with the majority having completed a university degree (38%, n = 34). Results: Themes indicated that participants were most interested in Facebook-style services (n = 17), chat groups (n = 16) and email-based services (n = 4) designed specifically for older adults (n = 14). However, some concerns were raised regarding the trustworthiness of Internet-based services, with the largest proportion of participants (n = 22) noting that they were unlikely to use Internet- or social media-based services. The primary content-related themes were mental fitness (n = 34), grief and loss (n = 20), health information (n = 13), socialisation (n = 11) and physical fitness (n = 10). Conclusions: Participants indicated interest in tailor-made Facebook-style services for older adults that allow them to communicate with their peers and create new social networks and incorporate content relating to strategies for working on mental and physical fitness, information on coping with grief and loss, as well as health information. These findings can be used by organisations to develop Internet-based services and content for older Australian adults. © 2023 The Authors.

- Description: Background: Powered wheelchairs and motorised mobility scooters, collectively called powered mobility devices (PMD), are highly valued by older Australians, including those living in residential care, to facilitate personal and community mobility. The number of PMDs in residential aged care is expected to grow proportionally with that of the wider community, however, there is very little literature on supporting residents to use PMDs safely. Prior to developing such supports, it is important to understand the frequency and nature of any incidents experienced by residents whilst using a PMD. The aim of this study was to determine the number and characteristics of PMD use related incidents occurring in a group of residential aged care facilities in a single year in one state in Australia including incident type, severity, assessment, or training received and outcomes on follow-up for PMD users living in residential aged care. Methods: Analysis of secondary data, including documentation of PMD incidents and injuries for one aged care provider group over 12 months retrospectively. Follow-up data were gathered 9–12 months post incident to review and record the outcome for each PMD user. Results: No fatalities were recorded as a direct result of PMD use and 55 incidents, including collisions, tips, and falls, were attributed to 30 residents. Examination of demographics and incident characteristics found that 67% of residents who had incurred incidents were male, 67% were over 80 years of age, 97% had multiple diagnoses and 53% had not received training to use a PMD. Results from this study were extrapolated to project that 4,453 PMD use related incidents occur every year within Australian residential aged care facilities, with the potential for outcomes such as extended recovery, fatality, litigation, or loss of income. Conclusion: This is the first time that detailed incident data on PMD use in residential aged care has been reviewed in an Australian context. Illuminating both the benefits and the potential risks of PMD use emphasizes the need to develop and improve support structures to promote safe PMD use in residential aged care. © 2023, Crown.

- Description: Objective: This study assessed the psychometric properties of the Caring Efficacy Scale (CES) among personal care attendants providing care to older residents in residential aged care settings. Methods: This cross-sectional study was completed in Australia in 2020–2021. Confirmatory factor analysis (CFA) of the 30-item original CES (Model 1) and 28-item CES validated in registered nurses (Model 2) was conducted to assess the goodness of fit of these models in our study population. Due to unsatisfactory fit indices for both models, exploratory factor analysis (EFA) was conducted to examine the dimensionality and underlying structure of the original CES among personal care attendants. Internal consistency of the final scale and subscales identified was examined using item-total correlations and Cronbach's alpha coefficients. Results: Two hundred and eighty personal care attendants participated in the study. The model fit indices such as Comparative Fit Index and Tucker Lewis Index of both models were less than 0.90, while the Standardised Root Mean Square Residual and Root Mean Square of Approximation values were greater than or equal to 0.08 and 0.06, respectively. The EFA identified a two-factor structure, and 22 items of the 30 in the original scale were retained. Item-total correlations amongst items retained in the scale and subscales were greater than 0.3. Cronbach's alpha for the abbreviated scale was 0.85, with 0.83 and 0.79, respectively, for the two subscales. Conclusions: The modified CES can be used as a robust tool to assess the self-efficacy of personal care attendants in providing care to older residents in residential aged care settings. © 2023 The Authors.

- Description: Background: Patient education is a professional obligation for all nurses. Public health messaging in emergency departments during disasters can help prevent further risk or illness for affected communities. In this study, Australian emergency nurse Key Informants share their perceptions and experiences of preventative messaging provided in their departments during disasters and the governance and processes in place to support this practice. Methods: The qualitative phase of a mixed methods study, where semi structured interviews were utilised, and data analysed using a six step Thematic analysis. Results: Three themes were identified: (1) Part of the Job; (2) It's all in the delivery; and (3) Preparation is the key. These themes include concepts involving the confidence and competence of nurses providing messages, what, when and how messages are being given and how prepared both the department and staff are regarding patient education during disaster events. Conclusions: Nurse confidence is a key factor in the delivery of preventative messages during disasters, potentially resulting from a lack of exposure, a junior workforce and minimal training. Leaders agree that departments are not preparing or supporting messaging practice, with an absence of specific training, formal guidelines, and patient education resources; and that improvement is needed. © 2023

Public health messaging in emergency departments during disasters can help prevent further risk or illness for affected communities. In this study, Australian emergency nurse Key Informants share their perceptions and experiences of preventative messaging provided in their departments during disasters and the governance and processes in place to support this practice. Methods: The qualitative phase of a mixed methods study, where semi structured interviews were utilised, and data analysed using a six step Thematic analysis. Results: Three themes were identified: (1) Part of the Job; (2) It's all in the delivery; and (3) Preparation is the key. These themes include concepts involving the confidence and competence of nurses providing messages, what, when and how messages are being given and how prepared both the department and staff are regarding patient education during disaster events. Conclusions: Nurse confidence is a key factor in the delivery of preventative messages during disasters, potentially resulting from a lack of exposure, a junior workforce and minimal training. Leaders agree that departments are not preparing or supporting messaging practice, with an absence of specific training, formal guidelines, and patient education resources; and that improvement is needed. © 2023

- Description: The present study aims to explore the utility of the Team Emergency Assessment Measure (TEAM) in relation to the enhancement of emergency team non-technical skills based on research conducted over the last decade. In this mapping review, a citation mining process identified 22 primary studies for inclusion, published between 2012 and 2022. It provides outcome data on emergency teams' non-technical skills following team training and/or real-life patient emergencies. Emergency team studies related to resuscitation teams (adult, paediatric, newborn and obstetric cases) and medical emergency team (MET) management of patient deterioration. Team performance ratings varied, ranging from approximately 90% for experienced clinical teams down to 38% for students. Statistically significant improvements in performance were notable following training and/or repeated practice. Validity evidence, across 11 studies that provided change data described positive learning outcomes and moderate intervention effects. However, according to Kirkpatrick's model of educational evaluation the studies were limited to professional development phases of learning and immediate post-training assessments rather than care quality improvement. The review highlights a lack of studies evidencing quality improvement or clinical impact such as change of patient care practice or health service performance. There is a need to conduct well-designed studies that explore both technical and non-technical skills of resuscitation teams and METs. Currently, non-technical skills training and repeated performance evaluations using the TEAM contribute immensely to the proficiency of emergency teams. © 2023 The Authors.

- Description: Introduction: Oxidative stress is one of many factors suspected to promote antinuclear autoantibody (ANA) formation. Reactive oxygen species can induce changes in the antigenic structure of macromolecules, causing the immune system to treat them as “neo-antigens” and start production of autoantibodies. This study was designed to evaluate the relationship between oxidative stress markers, lifestyle factors and the detection of ANA. Material and methods: We examined measures of oxidative stress indices of free-radical damage to lipids and proteins, such as total oxidant status (TOS), concentration of protein thiol groups (PSH), and malondialdehyde (MDA), activity of superoxide dismutase (SOD) in 1731 serum samples. The parameters of the non-enzymatic antioxidant system, such as total antioxidant status (TAS) and uric acid (UA) concentration, were also measured and the oxidative stress index (OSI-index) was calculated. All samples were tested for the presence of ANA using an indirect immunofluorescence assay (IIFA). Results: The presence of ANA in women was associated with lower physical activity (p = 0.036), less frequent smoking (p = 0.007) and drinking of alcohol (p = 0.024) accompanied by significant changes in SOD isoenzymes activity (p < 0.001) and a higher uric acid (UA) concentration (p < 0.001). In ANA positive males we observed lower concentrations of PSH (p = 0.046) and increased concentrations of MDA (p = 0.047). Conclusions: The results indicate that local oxidative stress may be associated with increased probability of ANA formation in a sex-specific manner. © 2021 Termedia & Banach.

- Description: Introduction: We tested two strategies that hypothetically increase serotonin availability (α-lactalbumin consumption and a remote submaximal handgrip contraction) on estimates of persistent inward currents (PICs) amplitude of soleus muscle in healthy participants. Methods: With a randomised, double-blind, and cross-over design, 13 healthy participants performed triangular-shaped ramp contractions with their plantar flexors (20% of maximal torque), followed by a 30-s handgrip sustained contraction (40% of maximal force) and consecutive repeated triangular-shaped contractions. This was performed before and after the consumption of either 40 g of α-lactalbumin, an isonitrogenous beverage (Zein) or an isocaloric beverage (Corn-starch). Soleus motor units discharge rates were analysed from high-density surface electromyography signals. PICs were estimated by calculating the delta frequency (ΔF) of motor unit train spikes using the paired motor unit technique. Results: ΔF (0.19 pps; p = 0.001; d = 0.30) and peak discharge rate (0.20 pps; p < 0.001; d = 0.37) increased after the handgrip contraction, irrespective of the consumed supplement. No effects of α-lactalbumin were observed. Conclusions: Our results indicate that 40 g of α-lactalbumin was unable to modify intrinsic motoneuron excitability. However, performing a submaximal handgrip contraction before the plantar flexion triangular contraction was capable of increasing ΔF and discharge rates on soleus motor units. These findings highlight the diffused effects of serotonergic input, its effects on motoneuron discharge behaviour, and suggest a cross-effector effect within human motoneurons. © 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.

- Description: Background Perinatal maternal depression may affect fetal neurodevelopment directly or indirectly via exposures such as smoking, alcohol, or antidepressant use. The relative contribution of these risk factors on child executive function (EF) has not been explored systematically. Methods A prospective pregnancy cohort of 197 women and their children was studied to determine whether maternal depression diagnosis and the trajectory of maternal depressive symptoms (MDSs) from early pregnancy to 12 months postpartum predicts child EF at age 4 (measured using the preschool age psychiatric assessment, NEPSY-II, and Shape School task) using latent growth curve modeling. Indirect effects of smoking, alcohol, and antidepressant use were also formally tested. Results Increasing maternal perinatal depressive symptoms over time predicted more inattentive symptoms, poorer switching, and motor inhibition, but not cognitive inhibition. When adjusted for multiple comparison, and after accounting for maternal cognition and education, the association with child inattentive symptoms remained significant. However, diagnosed depression did not predict child EF outcomes. Prenatal exposure to smoking, alcohol, and antidepressants also did not mediate pathways from depressive symptoms to EF outcomes. Our findings were limited by sample size and statistical power to detect outcome effects of smaller effect size. Conclusions This study suggests that increasing MDSs over the perinatal period is associated with poorer EF outcomes in children at age 4 - independent of prenatal smoking, drinking, or antidepressant use. Depressive chronicity, severity, and postpartum influences may play crucial roles in determining childhood outcomes of EF. Copyright © The Author(s), 2023. Published by Cambridge University Press.

- Description: Background: The successful use of extended reality (XR) in sport is highly dependent on the extent to which it can represent the perception–action couplings that exist in the performance setting. However, there are many unknowns regarding the effectiveness of XR technology which is limiting its adoption in sport. Therefore, providing high-performance sporting organisations with more information about the efficacy and utility of XR, specifically its strengths and limitations, is warranted. Results: The results provide insight into the limitations of XR and how those limitations are likely to reduce the effectiveness of XR for training motor skills. The participants described opportunities provided by XR for measuring athlete performance and highlighted several practical applications for enhancing athlete and coaching performance. Using artificial intelligence (AI) for training tactical decision-making and creating new movement solutions was also a key finding. Conclusions: The use of XR in sport is in its infancy, and more research is required to establish a deeper understanding of its utility and efficacy.

- Description: The current study aimed to qualitatively investigate the perceived determinants of success in professional esports athletes. Guided by the bioecological model (Bronfenbrenner & Morris, 2006), thematic analysis was used to explore elite esports athletes’ perceptions of success determinants. Semi-structured interviews were conducted with seven elite esports athletes. The interviews were used to investigate players’ psychology when playing well, training in elite esports, and working in esports teams. Deductive and inductive analyses were conducted to capture the core themes of success in esports within the bioecological model. When playing well, elite esports athletes experienced high levels of confidence, uninterrupted focus, and flow states. Elite esport athletes use mental strategies to help regulate their emotions and remain mindful in the presence of “tilt”. Furthermore, breathing techniques and tactical breaks were used when players felt nervous or when trying to “reset” from a stressful situation. When working in elite esport teams, players reported using strategies to improve team cohesion and that the biggest challenge was interpersonal disagreements. The results contribute to the growing body of literature highlighting the psychological similarities between elite esports and traditional sports athletes and serve as an index for future research into high-performance in esports. © 2021 Informa UK Limited, trading as Taylor & Francis Group.

Elite esport athletes use mental strategies to help regulate their emotions and remain mindful in the presence of “tilt”. Furthermore, breathing techniques and tactical breaks were used when players felt nervous or when trying to “reset” from a stressful situation. When working in elite esport teams, players reported using strategies to improve team cohesion and that the biggest challenge was interpersonal disagreements. The results contribute to the growing body of literature highlighting the psychological similarities between elite esports and traditional sports athletes and serve as an index for future research into high-performance in esports. © 2021 Informa UK Limited, trading as Taylor & Francis Group.

- Description: Background Military populations, including fast jet aircrew (FJA - aka fighter aircrew/pilots), commonly suffer from musculoskeletal complaints, which reduce performance and operational capability. Valid surveillance tools and agreed recordable injury definitions are lacking. Our objective was to develop and then evaluate the validity of a musculoskeletal complaints surveillance and monitoring tool for FJA. Methods A Delphi study with international experts sought consensus on recordable injury definitions and important content for use in a surveillance and monitoring tool for FJA. Using these results and feedback from end-users (FJA), the University of Canberra Fast Jet Aircrew Musculoskeletal Questionnaire (UC-FJAMQ) was developed. Following its use with 306 Royal Australian Air Force (RAAF) FJA over 4 × five-month reporting periods, validity of the UC-FJAMQ was evaluated via multi-level factor analysis (MFA) and compared with routine methods of injury surveillance. Results Consensus was achieved for: eight words/descriptors for defining a musculoskeletal complaint six definitions of recordable injury and 14 domains important for determining overall severity. The UC-FJAMQ was developed and refined. MFA identified three distinct dimensions within the 11 items used to determine severity: operational capability, symptoms, and care-seeking. MFA further highlighted that symptom severity and seeking medical attention were poor indicators of the impact musculoskeletal complaints have upon operational capability. One hundred and fifty-two episodes of time loss were identified, with the UC-FJAMQ identifying 79% of these, while routine methods identified 49%. Despite modest weekly reporting rates (61%), the UC-FJAMQ outperformed routine surveillance methods. Conclusions The UC-FJAMQ was developed to specifically address the complexities of injury surveillance with FJA, which are similar to those noted in other military and sporting populations. The results demonstrated the UC-FJAMQ to be sensitive and valid within a large group of FJA over 4 × five-month reporting periods. Adoption of consistent, sensitive, and valid surveillance methods will strengthen the FJA injury prevention literature, ultimately enhancing their health, performance, and operational capability.

- Description: The associations between high-density lipoprotein cholesterol (HDL-C) and blood pressure (BP) or hypertension are inconsistent in previous studies. This study aimed to assess these associations in a large cohort of Chinese adults and across different age groups. This cross-sectional association study included 22,081 Chinese adults. Associations of HDL-C with BP and hypertension were analyzed using linear or logistic regression, with or without adjustment for confounding factors. HDL-C was inversely associated with BP and hypertension. These associations were still apparent after adjustment for age, sex, fasting plasma glucose, and low-density lipoprotein cholesterol. Sub-analyses revealed: (1) in the whole cohort and females alone, HDL-C was inversely associated with BP and hypertension in young and middle-aged but not older participants; (2) in males alone, HDL-C was not associated with systolic BP or hypertension. However, HDL-C was either inversely, or not, or positively associated with BP in young, middle-aged, and older males, respectively. After further adjustment for body mass index (BMI), the negative associations of HDL-C with BP and hypertension in the whole cohort became positive ones, and the positive associations only presented in males. These findings suggest that further adjustment for BMI changes inverse associations of HDL-cholesterol with BP and hypertension to positive associations in a cohort of Chinese adults. © 2021, The Author(s), under exclusive licence to Springer Nature Limited.
