Abstract: Delayed recovery from concussion can dramatically affect a child's social, emotional, and educational development, yet little is known about what causes some children to recover faster than others. The contribution of white matter disruption in children with delayed recovery has been hypothesized, but findings are limited by methodological issues such as: small heterogeneous s les, bias toward children with delayed recovery, and inconsistencies in timing of brain imaging, both within and between studies. The aim of the present study was to assess diffusion neuroimaging correlates of delayed recovery post-concussion in children. A prospective, longitudinal, observational cohort study was conducted at a statewide tertiary pediatric hospital. Forty-three children who presented to the emergency department (ED) with concussion (defined according to the Zurich/Berlin Consensus Statement on Concussion in Sport) underwent magnetic resonance imaging (MRI) at a 2 weeks post-injury and were classified as either normally recovering (

Abstract: Susceptibility weighted imaging (SWI) and resting state functional magnetic resonance imaging have been highlighted as two novel neuroimaging modalities that have been underutilized when attempting to predict whether a child with concussion will recover normally or have a delayed recovery course. This study aimed to investigate whether there was a difference between children who recover normally from a concussion and children with delayed recovery in terms of SWI lesion burden and resting state network makeup. Forty-one children who presented to the emergency department of a tertiary level pediatric hospital with concussion participated in this study as a part of a larger prospective, longitudinal observational cohort study into concussion assessment and recovery. Children underwent neuroimaging 2 weeks post-injury and were classified as either normally recovering (

Abstract: The Sports Concussion Assessment Tool-5th Edition (SCAT5) and the child version (Child SCAT5) are the current editions of the SCAT and have updated the memory testing component from previous editions. This study aimed to validate this new memory component against the Rey Auditory Verbal Learning Test (RAVLT) as the validated standard. This prospective, observational study, carried out within The Royal Children's Hospital Emergency Department, Melbourne, Australia, recruited 198 participants: 91 with concussion and 107 upper limb injury or healthy sibling controls. Partial Pearson correlations showed that memory acquisition and recall on delay aspects of the SCAT5 were significantly correlated with the RAVLT equivalents when controlling for age (

Abstract: Research investigating neonatal arterial ischemic stroke (NAIS) outcomes have shown that combined cortical and basal ganglia infarction or involvement of the corticospinal tract predict cerebral palsy (CP). The research question was whether voxel-based lesion-symptom mapping (VLSM) on acute MRI can identify brain regions associated with CP and neurodevelopmental impairments in neonatal arterial ischemic stroke (NAIS). Newborns were recruited from prospective Australian and Swiss pediatric stroke registries. CP diagnosis was based on clinical examination. Language and cognitive-behavioral impairments were assessed using the Pediatric Stroke Outcome Measure, dichotomized to good (0-0.5) or poor (≥ 1), at ≥18 months of age. Infarcts were manually segmented using diffusion-weighted imaging, registered to a neonatal-specific brain template. VLSM was conducted using MATLAB SPM12 toolbox. A general linear model was used to correlate lesion masks with motor, language and cognitive-behavioral outcomes. Voxel-wise t- test statistics were calculated, correcting for multiple comparisons using family-wise error rate (FWE). Eighty-five newborns met inclusion criteria. Infarct lateralization was left hemisphere (62%), right (8%) and bilateral (30%). At median age 2.1 years (IQR 1.9-2.6), 33% developed CP and 42% had neurological impairments. 54 grey and white matter regions correlated with CP (t .33 FWE .05), including primary motor pathway regions, such as the precentral gyrus, and cerebral peduncle, and regions functionally connected to the primary motor pathway, such as the pallidum, and corpus callosum motor segment. No significant correlations were found for language or cognitive-behavioral outcomes. CP following NAIS correlates with infarct regions directly involved in motor control and , or in functionally connected regions. Areas associated with language or cognitive-behavioral impairment are less clear.

Abstract: Workplace violence, incidents against people in their workplaces, is a growing problem in Australia causing untold personal suffering as well as costing Australian businesses in productivity. Midwives have been highlighted as a group particularly at risk, yet in Australia there is little research into workplace violence against midwives and even less into midwifery students. This study aimed to explore Australian midwifery students' responses to workplace violence as well as to gauge the impact of workplace violence on them. Cross-sectional survey design was employed. Second and third year students were invited to participate at the end of a scheduled lecture. Fifty-two female midwifery students who had completed their work placement completed a survey indicating their immediate responses to workplace violence as well as the Impact of Event Scale. Data were analysed using descriptive statistics. Most students notified a co-worker immediately after a workplace violence incident, yet few completed an incident form or received official debriefing. There is a need for the reporting of workplace violence against midwifery students to be made easier to access thereby ensuring they can receive the assistance they require. Midwifery students need to understand the processes and supports in place for managing instances of workplace violence. Clinical placements can impact on midwifery students' future careers. Universities need to prepare students for the possibility of workplace violence and arm them with appropriate strategies for safely dealing with it.

Abstract: Healthcare workers often monitor patients while moving between different locations and tasks, and away from conventional monitoring displays. Vibrotactile displays can provide patient information in vibrotactile patterns that are felt regardless of the worker's location. We examined how effectively participants could identify changes in vibrotactile representations of patient heart rate (HR) and oxygen saturation (SpO₂). In Experiment 1, participants identified changes in HR and SpO₂ with greater than 90% accuracy while using vibrotactile displays configured in either an integrated or a separated format. In Experiment 2, incidental auditory and visual cues were removed and performance was still greater than 90% for the integrated display. In Experiments 3 and 4, ongoing tasks with low or high task load were introduced high load worsened participants' response accuracy and speed at identifying vital signs. In Experiments 5 and 6, alternative designs were tested, including a design with a seemingly more natural mapping of HR to vibrotactile stimulation. However, no design supported more accurate performance than the integrated display. Results are interpreted with respect to multiple resource theory, and constraints on conforming to design guidelines are noted. Vibrotactile displays appear to be viable and therefore potentially suitable for use in healthcare and other contexts. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Abstract: Prior investigations of vibrotactile displays suggest they have promise for use in the healthcare domain. This exploratory study forms part of a series exploring the use of an upper arm, continuously informing, vibrotactile display of pulse oximetry for clinicians. The study focused on the effect of vigilance on participants’ accuracy and latency for detecting and identifying changes in vital sign levels. Twenty-one participants were tested in a within-subjects design in four blocks of approximately 18 minutes duration each. Two blocks were a low workload condition and the other two blocks a high workload condition. Data were analysed against thresholds of 90% for accuracy and 10 seconds for response latency and workload conditions were also compared for accuracy and latency. Participants’ accuracy was not better than 90% and response latency was not shorter than 10 seconds, even in the low workload conditions. Participants were slower to detect changes in the high workload condition, and detection time worsened as the experiment progressed. Taken together, the results suggest that detecting rare events places a high strain on cognition and negatively affects performance. These findings have implications for the use of vibrotactile displays and will guide further investigations into the use of vibrotactile technology in healthcare.
