An assessment of the utility and functionality of wearable head impact sensors in Australian Football. | LitMetric

AI Article Synopsis

Article Abstract

Objectives: To assess the utility and functionality of the X-Patch as a measurement tool to study head impact exposure in Australian Football. Accuracy, precision, reliability and validity were examined.

Designs: Laboratory tests and prospective observational study.

Methods: Laboratory tests on X-Patch were undertaken using an instrumented Hybrid III head and neck and linear impactor. Differences between X-Patch and reference data were analysed. Australian Football players wore the X-Patch devices and games were video-recorded. Video recordings were analysed qualitatively for head impact events and these were correlated with X-Patch head acceleration events. Wearability of the X-Patch was assessed using the Comfort Rating Scale for Wearable Computers.

Results: Laboratory head impacts, performed at multiple impact sites and velocities, identified significant correlations between headform-measured and device-measured kinematic parameters (p<0.05 for all). On average, the X-Patch-recorded peak linear acceleration (PLA) was 17% greater than the reference PLA, 28% less for peak rotational acceleration (PRA) and 101% greater for the Head Injury Criterion (HIC). For video analysis, 118 head acceleration events (HAE) were included with PLA ≥30g across 53 players. Video recordings of X-Patch-measured HAEs (PLA ≥30g) determined that 31.4% were direct head impacts, 9.3% were indirect impacts, 44.1% were unknown or unclear and 15.3% were neither direct nor indirect head impacts. The X-Patch system was deemed wearable by 95-100% of respondents.

Conclusions: This study reinforces evidence that use of the current X-Patch devices should be limited to research only and in conjunction with video analysis.

Evaluating the impact of dose monitoring software alerts on radiation dose reduction in computed tomography: A systematic review.

Eur J Radiol

December 2024

Medical Image Optimisation and Perceptions Group, Discipline of Medical Imaging Science, Faculty of Medicine and Health, The University of Sydney, Australia. Electronic address:

Introduction: Radiation Dose Monitoring Software (DMS) tools have been developed to monitor doses and alert computed tomography (CT) users of high radiation exposure. However, the causal factors for alerts and the impact of DMS in dose optimisation are poorly understood.

Aim: This review aims to identify high-dose CT examinations triggering alerts and their determinants, and to assess if the alerts from DMS help to reduce CT dose levels.

The aim of the present study was to employ CELLSEARCH technology for the detection of circulating tumor cells (CTCs) in the peripheral blood of head and neck cancer (HNC) patients, and to assess the association between CTC count and patient prognosis. In this retrospective study, a cohort of 56 patients diagnosed with HNC and receiving treatment at the Department of Otolaryngology, Head and Neck Surgery (Beijing Tongren Hospital) between December 2013 and June 2018 were selected. Utilizing CELLSEARCH technology, the presence of CTCs were detected in samples of peripheral blood from patients with head and neck cancer (HNC) patients, and CTC counts were documented.

Purpose: To assess the feasibility and benefit of NTCP optimized aspiration-prevention treatment planning by sparing specific aspiration related organs at risk, and to assess the impact of baseline complaints on the planning results.

Materials And Methods: This in silico planning study included 30 HNC patients who were previously treated with definitive radiotherapy. New fully automated plans, allowing for sparing specific aspiration related organs at risk, were optimised directly on normal tissue complication probability (NTCP) models for common toxicities: xerostomia and dysphagia.

Background: This study aimed to assess combined supraclavicular lymph node dissection (SLND) and radiotherapy (RT) versus standalone radiotherapy for efficacy in newly diagnosed breast cancer patients with ipsilateral supraclavicular lymph node metastasis (ISLNM).

Methods: Totally 143 ISLNM patients treated between 2014 and 2021 in two medical institutions were examined retrospectively. Patients were divided into two groups to undergo combined SLND and radiotherapy (surgery + RT, n = 73) or radiotherapy alone (RT, n = 70).
