Abstract
BACKGROUND Oral health promotion initiatives must be evidence-based and consistent with broader health messaging. The Oral Health Messages for the Australian Public were first produced in 2009 and sought to enable a focused, and strategic approach to oral health promotion in Australia. As the evidence base and needs of the Australian population have since changed, this consensus statement was updated in 2022-2023. METHODS The process of updating the messages consisted of 3 phases (preparatory phase, the Delphi technique, final revision phase). The preparatory phase included public and expert consultation, an umbrella review of published scientific literature and review of available recommendations, policies and guidelines. The Delphi technique used in this study was guided by Guidance on Conducting and REporting DElphi Studies (CREDES) and included 2 voting rounds. There were 70 experts in round 1 and 60 experts in round 2. Delphi participants comprised of experts from a variety of fields to ensure diversity and inclusion, balance expertise and maximize stakeholder representation. Consensus was defined as 75% agreement. RESULTS A total of 11 messages were included in the 2022 update of Oral Health Messages for Australia. CONCLUSION The updated oral health messages will support oral health promotion policy and activity at both individual and population level to improve the oral health of Australians.

Abstract
INTRODUCTION Public service provision is one of the keys to reducing inequalities in the utilization of dental services. Given the increase in the aging population, there should be a focus on older adults' oral health. However, this is often overlooked. OBJECTIVES This study investigates the effectiveness of public services in reducing income-related inequalities in dental service utilization among older South Australians. METHODS A multiple counterfactual mediation analysis using the ratio of mediator probability weighting approach was used to explore the proposed mediation mechanism using a South Australian population of older adults (≥65 y). The exposure variable in the analysis was income, and the mediators were concession cards and the last dental sector (public or private). The outcome variable was the time of last dental visit. RESULTS Half of the older adults with high income (≥$40,000) owned a concession card, and 10% of those who attended public dental services belonged to this group. Interestingly, only 16.3% of the study participants had visited the public dental sector at their last dental appointment. Results showed a negligible indirect effect (odds ratio [OR], 0.99; 95% confidence interval [CI], 0.85-1.05) and a significant direct effect (OR, 3.09; 95% CI, 2.24-4.87). By changing the potential outcome distributions to the counterfactual exposure distributions and taking the mediators' distribution as a counterfactual exposure distribution, the odds of dental visits occurring before the past 12 mo approximately tripled for low-income compared to high-income individuals. CONCLUSION Income inequalities were associated with relatively delayed dental visits in older South Australians, and provision of public services could not improve this pattern. This might happen due to inequitable access to concession cards and public services. A review of policies is required, including addressing income inequalities and implementing short-term approaches to improve service utilization patterns in older South Australians. KNOWLEDGE TRANSFER STATEMENT The findings of this study can enable policymakers for informed decision-making about the provision of public dental services for older Australians. This study emphasizes the importance of reviewing the current public dental services and subsidies and implementing short-term approaches to reduce income inequalities for older Australians.

Abstract
OBJECTIVE To determine if there were concussion diagnosis and recovery disparities between collegiate athletes with Black and White racial identities. DESIGN Retrospective cohort study. METHODS Concussion information was extracted from NCAA athlete medical files at LIMBIC MATARS member institutions from the 2015-16' to 2019-20' academic years. A total of 410 concussions from 9 institutions were included that provided all independent (i.e. racial identity of Black or White) and dependent variable information (i.e. dates of injury, diagnosis, symptom resolution, and return to sport) that were analyzed using Mann-Whitney U tests. The sample consisted of 114 (27.8%) concussions sustained by Black athletes and 296 (72.1%) sustained by White athletes. RESULTS The overall sample had a median of 0 days between injury occurrence to diagnosis, 7 days to symptom resolution, and 12 days to return to sport. No significant timing differences were observed for concussion diagnosis (p = .14), symptom resolution (p = .39), or return to sport (p = 0.58) between collegiate athletes with Black versus White racial identities. CONCLUSIONS These findings may reflect equitable access to onsite sports medicine healthcare resources that facilitate concussion management in the collegiate sport setting. Future work should explore these associations with a larger and more diverse sample of collegiate athletes.

Abstract
OBJECTIVE To use a simple method of needle blunting to produce a placebo dry needling protocol which is indistinguishable from the sensations felt during therapeutic dry needling. METHODS A randomised cross-over design was used to compare the perception of needle skin penetration, pain experienced and types of sensations experienced following a single placebo dry needling and a single therapeutic dry needling application. RESULTS There were no significant differences in the proportions of patients reported ability to perceive needle penetration (p = 0.646), description of needling sensations (p = 0.3) or pain rating (p = 0.405) when comparing placebo needling to therapeutic dry needling. CONCLUSION Needle tip bending creates a simple, cost-effective and effective placebo needle for use in comparisons with therapeutic dry needling. This offers researchers a viable alternative to expensive and inappropriate acupuncture sham devices when conducting dry needling trials.

Abstract
Abstract
Aim
Many vascular patients present acutely, relying on emergency theatre availability when surgical intervention is required. The prioritisation of the CEPOD operating list is a challenge, and the additional pressures of the COVID-19 pandemic have necessitated changes to established practice. The purpose of this audit was to review the effects of the pandemic on the CEPOD waiting times for vascular patients at the main centre for the South West Wales Vascular Network.
Method
The CEPOD waiting times for vascular patients during the initial wave of the COVID-19 pandemic were compared with the same period the previous year. Data was analysed according to booking category and procedure type.
Results
98 emergency vascular procedures were performed during the initial wave of the COVID pandemic, compared to 133 in 2019. In 2019, amputations (major and minor) accounted for 47% of cases, which rose to 53% during the pandemic. Median waiting times for category 1 and 2a operations were significantly shorter in 2020, whilst category 3 waiting times rose. There was no significant difference overall in the proportion of patients operated on within the target timescale, regardless of CEPOD booking category.
Conclusions
Managing the impact of COVID-19 required change to established practice. Although fewer procedures were performed, significant logistical challenges were faced. By adjusting the organisation of CEPOD, the most urgent vascular cases were performed quicker during this time. It is important to identify and promote the positive organisational changes that have arisen as a result of COVID-19, and to continue to review procedures as the pandemic progresses.

Abstract
Abstract
In this paper, the authors present a case diagnosed as ‘metaplastic thymic sarcoma’. Tumours of the thymus are extremely rare: there is a disparity in terminology and histology observed, although there have been efforts to make classification clearer. The reported case concerns a seventy-eight-year-old woman, who presented with a rapidly enlarging neck mass. Histological diagnosis was made challenging by the unusual characteristics of the tumour; the diagnosis of ‘metaplastic thymic sarcoma’ was eventually established, following consultation with an internationally renowned soft tissue pathologist. Review of the relevant literature demonstrated no comparable cases; the presentation of a thymic tumour within the thyroid is also considered unusual. The tumour observed did not conform to any previously sub type of thymic tumour and is therefore believed to be a distinct entity. The patient suffered aggressive recurrence of the disease shortly after her surgery. Genetic testing indicated the tumour was BRAF positive, and there was a dramatic clinical response to Dabrafenib/ Trametinib treatment. The successful use of immunotherapy is encouraging finding, however the diagnosis of another distinct sub type of thymic tumour, further demonstrates the diagnostic and therapeutic challenges presented by this rare and heterogenous group.

Abstract
Abstract
Aim
VTE prophylaxis is a vital aspect of patient safety. The decision whether to offer pharmacological thromboprophylaxis is a balance of risk versus benefit. There is a low incidence of VTE in ENT patients, admissions are often short and active bleeding on admission is not uncommon (epistaxis patients, already on anticoagulation are particularly difficult to manage}. There are no clear, specialty specific guidelines to assist in these frequently encountered endeavours.
Method
The number of emergency ENT admissions who had a documented VTE during admission or in the 28 days following was used to calculate the incidence of VTE in acute admissions. An audit of VTE prophylaxis and documentation was also conducted using 20 admissions over 24 hours.
Results
Incidence was 0.12%. 75% had a documented VTE risk assessment. Only 50% patients were prescribed chemical and mechanical thromboprophylaxis. 0% had appropriately documented that the patient did not require thromboprophylaxis on the drug chart (as per trust guidelines).
Conclusions
The results showed that both documentation and prescribing related to VTE prevention were poor. By highlighting the low incidence amongst this patient group, we were able to establish clearer guidance for VTE prophylaxis in acute ENT admissions and a protocol to standardise the management of anticoagulation in actively bleeding epistaxis patients.

Abstract
Abstract
Aim
Swansea Bay University Health Board have a caseload of 37 surgical voice restoration (SVR) laryngectomies. These patients are excellently managed during working hours, by a SALT-led service. Concerns were raised regarding the quality of out of hours management: the aim of this project was to identify and address the factors contributing to the difference in care received.
Method
A questionnaire was sent to current junior doctors to assess knowledge and confidence when managing SVR patients. Phone interviews were conducted with SVR patients to discuss the issues from a patient’s perspective. The junior doctor team and SALT team liaised to identify contributing logistical issues.
Results
The junior doctor survey indicated both experience and confidence were low, including amongst senior trainees. 58.3% were unfamiliar with equipment used to change a speech valve. Patient interviews revealed several issues, such as delays to treatment and unnecessary admissions. Logistical concerns included inability to access equipment out of hours and an absence of departmental guidelines.
Conclusions
This project demonstrates a collaborative approach between junior doctors and SALT, to improve the quality of care for a sub-set of patients with highly specialised needs. We identified the contributing factors for the disparity in services and tailored interventions to provide the junior doctors responsible for out of hours care, with the knowledge and skills to provide a better standard of care.

Abstract
Abstract
Aim
Single use nasal endoscopes have become increasingly popular since the COVID-19 pandemic. By avoiding the risk of cross contamination and reducing exposure by eliminating the need for re-processing, the disposable scopes have clear safety benefits. Despite ENT UK guidelines recommending that disposable nasal endoscopes be available in every department for use in emergencies, they have often been considered prohibitively expensive. The aim of this study was to analyse the costs associated with traditional nasal endoscopes and compare them to the single use scopes.
Method
A micro costing exercise was undertaken in three ENT departments: 2 university hospitals, and 1 district general hospital. The outcomes were compared and discussed with relation to the logistics of the departments, as well as organizational considerations.
Results
Cost per procedure varied according to the reprocessing methods used in the different departments. The cost of the disposable nasal endoscopes appears high, however there are many hidden costs associated with the traditional scopes, which can be difficult to quantify accurately.
Conclusions
Although disposable endoscopes appear costly, reprocessing and frequent repairs required for re-usable scopes account for the comparable cost per procedure. The high risk of COVID-19 transmission from examining the upper aerodigestive tract means that the safety benefits bear more weight in the current climate. However, concerns regarding environmental impact, image quality and storage of examinations also need to be considered.

Abstract
Abstract
Aim
Antibiotic prophylaxis to reduce the incidence of surgical site infections following excision of ulcerated skin lesions is frequently recommended, although the evidence base is limited. Current Swansea Bay guidelines recommend pre-operative administration of antibiotics: for procedures performed under local anaesthetic in the Plastic Surgery Treatment Centre (PSTC), oral route is preferable. It was noted that a number of patients were experiencing nausea and vomiting following administration of the recommended oral agent (doxycycline). The aim of this audit was to quantify the proportion of patients experiencing adverse effects, and to assess whether the prophylactic dose was being administered within the recommended time frame.
Method
Data was collected over a three-week period (28/10/20- 18/11/20). All patients that received doxycycline pre-operatively during this period were included: the time the doxycycline was given, the time of operation and whether there were any adverse effects was recorded for each patient.
Results
14 patients received doxycycline during the monitored period. On average the doxycycline was given 52 minutes prior to the procedure. 2 patients received their doxycycline dose after their procedures. 4 patients experienced side effects from the doxycycline (3 vomited, 1 nausea), the average time this subset of patients received their dose was 50 minutes prior to their procedure.
Conclusions
A significant proportion of patients experience adverse after receiving doxycycline, whilst there is limited evidence to prove its benefits. Trust guidelines are under review to consider alternative antibiotics, but better evidence is required to clarify the need for antibiotic prophylaxis for ulcerated lesions.

Abstract
A multi-energy soft x-ray pinhole camera has been designed, built, and deployed at the Madison Symmetric Torus to aid the study of particle and thermal transport, as well as MHD stability physics. This novel imaging diagnostic technique employs a pixelated x-ray detector in which the lower energy threshold for photon detection can be adjusted independently on each pixel. The detector of choice is a PILATUS3 100 K with a 450 μm thick silicon sensor and nearly 100 000 pixels sensitive to photon energies between 1.6 and 30 keV. An ensemble of cubic spline smoothing functions has been applied to the line-integrated data for each time-frame and energy-range, obtaining a reduced standard-deviation when compared to that dominated by photon-noise. The multi-energy local emissivity profiles are obtained from a 1D matrix-based Abel-inversion procedure. Central values of Te can be obtained by modeling the slope of the continuum radiation from ratios of the inverted radial emissivity profiles over multiple energy ranges with no a priori assumptions of plasma profiles, magnetic field reconstruction constraints, high-density limitations, or need of shot-to-shot reproducibility. In tokamak plasmas, a novel application has recently been tested for early detection, 1D imaging, and study of the birth, exponential growth, and saturation of runaway electrons at energies comparable to 100 × Te,0; thus, early results are also presented.

Abstract
Supermagnetosonic perpendicular flows are magnetically driven by a large radius theta-pinch experiment. Fine spatial resolution and macroscopic coverage allow the full structure of the plasma-piston coupling to be resolved in laboratory experiment for the first time. A moving ambipolar potential is observed to reflect unmagnetized ions to twice the piston speed. Magnetized electrons balance the radial potential via Hall currents and generate signature quadrupolar magnetic fields. Electron heating in the reflected ion foot is adiabatic.

Abstract
A compact multi-energy soft x-ray diagnostic is being installed on the W Environment in Steady-state Tokamak (WEST), which was designed and built to test ITER-like tungsten plasma facing components in a long pulse (∼1000 s) scenario. The diagnostic consists of a pinhole camera fielded with the PILATUS3 photon-counting Si-based detector (≲100 kpixel). The detector has sensitivity in the range 1.6-30 keV and enables energy discrimination, providing a higher energy resolution than conventional systems with metal foils and diodes with adequate space and time resolution (≲1 cm and 2 ms). The lower-absorption cut-off energy is set independently on each one of the ∼100 kpixels, providing a unique opportunity to measure simultaneously the plasma emissivity in multiple energy ranges and deduce a variety of plasma parameters (e.g., Te, nZ, and ΔZeff). The energy dependence of each pixel is calibrated here over the range 3-22 keV. The detector is exposed to a variety of monochromatic sources-fluorescence emission from metallic targets-and for each pixel, the lower energy threshold is scanned to calibrate the energy dependence. The data are fit to a responsivity curve ("S-curve") that determines the mapping between the possible detector settings and the energy response for each pixel. Here, the calibration is performed for three energy ranges: low (2.3-6 keV), medium (4.5-13.5 keV), and high (5.4-21 keV). We determine the achievable energy resolutions for the low, medium, and high energy ranges as 330 eV, 640 eV, and 950 eV, respectively. The main limitation for the energy resolution is found to be the finite width of the S-curve.

Abstract
Here we report epigenomic and transcriptomic changes in a prototypical J774 macrophage after engulfing talc or titanium dioxide particles in presence of estrogen. Macrophages are the first immune cells to engage and clear particles of various nature. A novel paradigm is emerging, that exposure to so-called 'inert' particulates that are considered innocuous is not really free of consequences. We hypothesized that especially the insoluble, non-digestible particles that do not release a known hazardous chemical can be underappreciated agents acting to affect the regulation inside macrophages upon phagocytosis. We performed gene chip microarray profiling and found that talc alone, and especially with oestrogen, has induced a substantially more prominent gene expression change than titanium dioxide; the affected genes were involved in pathways of cell proliferation, immune response and regulation, and, unexpectedly, enzymes and proteins of epigenetic regulation. We therefore tested the DNA methylation profiles of these cells via epigenome-wide bisulphite sequencing and found vast epigenetic changes in hundreds of loci, remarkably after a very short exposure to particles; ELISA assay for methylcytosine levels determined the particles induced an overall decrease in DNA methylation. We found a few loci where both the transcriptional changes and epigenetic changes occurred in the pathways involving immune and inflammatory signalling. Some transcriptomic and epigenomic changes were shared between talc and titanium dioxide, however, it is especially interesting that each of the two particles of similar size and insoluble nature has also induced a specific pattern of gene expression and DNA methylation changes which we report here.

Abstract
Abstract
Objective
To measure time-to-unrestricted participation in high school athletes following a sport-related concussion (SRC) diagnosis.
Method
This was a descriptive epidemiological study using the Michigan High School Athletic Association (MHSAA) online Head Injury Reporting System (HIRS). This study included 10,411 (65.9%) male and 5,412 (34.1%) female SRC cases that occurred in 20 sports with greater than 30 SRC cases during the 2015–2016 to 2018–2019 academic years. The HIRS includes dates for SRC injury events and medical clearance for unrestricted return-to-participation for each case; dates were used to calculate recovery time. Kaplan-Meier time-to-event analysis identified crude proportions of athletes that had not obtained medical clearance in weekly increments (e.g., 7 days, 14 days, 21 days, 28 days, 35 days) across sports.
Results
The median time-to-unrestricted participation was 11 days. Overall, 71.8% of SRC cases took longer than 7 days to return, 29.6% of SRC cases took longer than 14 days, 13.1% of cases took longer than 21 days to return, and 6.5% took longer than 28 days to return to their respective sports. Results by sport show that over 25% of gymnasts took longer than 28 days to return-to-unrestricted participation, followed by competitive cheerleaders (15.5%), wrestlers (12.1%), and male divers (12.0%).
Conclusions
Almost one in three high school athletes with SRC took longer than 14 days to return-to-unrestricted participation. These results serve as proportional time estimates for return-to-unrestricted participation across a sample of 20 high school sports; and provide rationale to further evaluate recovery patterns in individual sport groups.

Abstract
Abstract
Introduction
CPAP adherence may drop substantially over a long time frame. Since minorities including Hispanics and low socioeconomic groups have lower short-term acceptance and adherence, long-term adherence may also be reduced. We adapted a brief motivational enhancement education program (BMEEP) (Lai, CHEST 2014) in a Los Angeles County safety-net sleep clinic and found improved CPAP adherence at 3 months. We now report longitudinal long-term adherence over >=2 years. Our hypothesis: Many patients would meet CMS adherence criteria over >= 2 years.
Methods
During 3/1/2016 - 4/1/17, 118 patients completed BMEEP during CPAP initiation and were scheduled for a reinforcement session and routine clinic visits at 1 and 3 months and every 6 months thereafter. Electronic adherence and efficacy data were accessed each visit. Multivariate regression analyses explored association of adherence variables with demographic, clinical and workflow features.
Results
Baseline characteristics (mean (SD) or percent): Age 57.2 (17.8); Women 44.9%; Hispanic 69.5%, Non-Hispanic-White 22.9%, Other 5%, Black 3%; BMI 37; Epworth score 10.4 (6.05). Home sleep testing (69 patients) respiratory event indices were >=15/hr in 67% and >=30/hr in 57%. Polysomnography (81 patients) apnea hypopnea indices were (AHI) >= 15 in 78% and >=30/hr in 43%. By 7/1/2019, 23 (19%) patients were lost with unknown CPAP use status, while 76 (70.5%) of remaining patients continued to use CPAP. At 2 years, CPAP adherence parameters included: Average nightly use, 75% (27.7); Average hours/night, 4.74 (2.5); Average nightly use >=4 hours, 65.2% (31.6); >=70% nightly use >= 4 hours, 35 (51.5%). Average residual AHI was 2.05 (1.69). Adherence parameters in individual patients remained similar throughout 2 years. Long-term adherence was not associated with the demographic, clinical or workflow variables tested.
Conclusion
Programs that educate, motivate and provide regular follow-up for predominantly Hispanic low income populations can achieve acceptable long-term CPAP adherence rates.

Abstract
OBJECTIVE The number of medical mobile phone applications continues to grow. Although otorhinolaryngology-specific applications represent a small proportion, there are exciting innovations emerging for the specialty. This article will assess the number of applications available and review how they may be used in clinical practice. METHOD The application stores of the two most popular mobile phone platforms, Apple and android, were searched using multiple search terms. RESULTS A total of 107 ENT applications were identified and categorised according to intended use. Eight applications were reviewed in more detail and assessed on whether a doctor or allied health professional was involved in their design and if they were evidence-based. CONCLUSION There are a number of ENT-specific smartphone applications currently available. As the technology progresses, their scope has extended beyond being purely for reference. Nevertheless, it remains difficult to assess the validity and security of these applications.

Abstract
The degree of accuracy in surgery duration estimation directly impacts on the quality of planned surgical lists. Model selection for the prediction of surgery duration requires technical expertise and significant time and effort. The result is often a collection of viable models, the performance of which varies across different strata of the surgical population. This paper proposes a prediction framework to be used after a comprehensive model selection process has been completed for surgery duration prediction. The framework produces a partition of the surgical cases and a "hybrid model" that allocates different predictors from the collection of viable models to different parts of the surgical population. The intention is a flexible prediction process that can reassign models and adapt as surgical processes change. The framework is tested via a simulation study, and its utility is demonstrated by predicting surgery durations for Ear, Nose and Throat surgeries in a New Zealand hospital. The results indicate that the hybrid model is effective, performing better than standard model selection in two of the three simulation studies, and marginally worse when the selected model was the true underlying process.

Abstract
BACKGROUND STAMPEDE has previously reported that the use of upfront docetaxel improved overall survival (OS) for metastatic hormone naïve prostate cancer patients starting long-term androgen deprivation therapy. We report on long-term outcomes stratified by metastatic burden for M1 patients. METHODS We randomly allocated patients in 2 : 1 ratio to standard-of-care (SOC; control group) or SOC + docetaxel. Metastatic disease burden was categorised using retrospectively-collected baseline staging scans where available. Analysis used Cox regression models, adjusted for stratification factors, with emphasis on restricted mean survival time where hazards were non-proportional. RESULTS Between 05 October 2005 and 31 March 2013, 1086 M1 patients were randomised to receive SOC (n = 724) or SOC + docetaxel (n = 362). Metastatic burden was assessable for 830/1086 (76%) patients; 362 (44%) had low and 468 (56%) high metastatic burden. Median follow-up was 78.2 months. There were 494 deaths on SOC (41% more than the previous report). There was good evidence of benefit of docetaxel over SOC on OS (HR = 0.81, 95% CI 0.69-0.95, P = 0.009) with no evidence of heterogeneity of docetaxel effect between metastatic burden sub-groups (interaction P = 0.827). Analysis of other outcomes found evidence of benefit for docetaxel over SOC in failure-free survival (HR = 0.66, 95% CI 0.57-0.76, P < 0.001) and progression-free survival (HR = 0.69, 95% CI 0.59-0.81, P < 0.001) with no evidence of heterogeneity of docetaxel effect between metastatic burden sub-groups (interaction P > 0.5 in each case). There was no evidence that docetaxel resulted in late toxicity compared with SOC: after 1 year, G3-5 toxicity was reported for 28% SOC and 27% docetaxel (in patients still on follow-up at 1 year without prior progression). CONCLUSIONS The clinically significant benefit in survival for upfront docetaxel persists at longer follow-up, with no evidence that benefit differed by metastatic burden. We advocate that upfront docetaxel is considered for metastatic hormone naïve prostate cancer patients regardless of metastatic burden.

Abstract
Abstract
Background
The growing challenges and opportunities of Big Data for Public Health have revealed the potential to improve the efficiency and cost-effectiveness of public policy, for example through better targeting of resources with regard to General Practice (GP) prescribing. Open data has an important role due to its easy access and potential to complement proprietary data sources from, e.g., regional hospitals, and also itself be complemented with social data acquired by specialized approaches.
Methods
MIDAS pipeline of open source tools aiming integrating, analysing and visualising Open Data enabling health professionals and decision-makers to: (i) improve the usability of open data in combination with proprietary data through combining multiple visualisation tools in an integrated dashboard (ii) to explore the meaning of data in a global/local context based on new information using tone analysis and natural language techniques; and (iii) to have better informed decision-making based on evidence from trusted knowledge-bases. Specific data sources used have included information extracted from the biomedical database MEDLINE, worldwide news and government open data. Social media sources have also been used to gather information from the general public.
Results
Results include a strong correlation between antidepressant prescribing and economic deprivation, and a wide variation in how individual GP practices respond to demographic conditions. Automated anomaly detection based on the Local Outlier Probability has also been shown to be an easily understood and controllable approach to identifying prescribing outliers.
Conclusions
MIDAS demonstrates the significant value of open data from heterogeneous sources as basis decision-making in public health and healthcare, particularly when it is combined with proprietary or closed datasets. A key challenge in this regard is the ability to integrate and utilize data from diverse sources in a variety of formats and standards.
Key messages
MIDAS is exemplar on tackling the need for improved standards of open data, and new software architectures, tools and platforms addressing a complex ecosystem of heterogenous data sources and formats. MIDAS demonstrates the significant value of open data from heterogeneous sources as basis decision-making in public health and healthcare, particularly when combined with proprietary datasets.

Abstract
Abstract
Purpose
The ImPACT™ Quick Test (QT) is a brief iPad-based battery of neurocognitive tests that has been standardized on a sample of children, adolescents, and adults (ages 12-70). We sought to provide information regarding the prevalence of low ImPACT™ QT scores in the normative sample to improve clinical interpretation and reduce the risk of over-interpreting, or misinterpreting, a single low score.
Methods
Participants included 616 individuals ranging in age from 12 to 70, who were assessed individually. The ImPACT QT includes five subtests, contributing to three factor scores: Motor Speed, Memory, and Attention Tracker. The prevalence of low factor scores, stratified by age and gender, were calculated using multivariate base rates.
Results
In the total sample, obtaining 1 score below the 25th percentile was common (base rate, BR=31.8%), but obtaining 2 or more scores in this range was uncommon (BR=13.3%). Similarly, obtaining 1 score below the 16th percentile was common (BR=22.3%), but obtaining two or more scores in this range was very uncommon (BR=5.4%). There were small differences in base rate between genders and the number of low scores were fairly similar across the age groups.
Conclusion
Results from this study parallel previous work illustrating that a substantial percentage of healthy individuals will obtain one or more low test score when administered a battery of multiple cognitive test measures. Given that some healthy, non-concussed individuals will obtain a single score below expected cut-offs, clinicians should caution against overinterpreting a single low test score.

Abstract
Abstract
Purpose
To examine the effects of premorbid migraine history on baseline Vestibular/Ocular Motor Screening (VOMS) and King-Devick (KD) test performance in youth athletes.
Methods
This study implemented a cross-sectional design and was conducted at a series of youth sport venues in a designated research area. Youth athletes between the ages of 8 and 14 years with a diagnosed history of migraine headaches (n=28) and match controls (n=28) were administered a baseline VOMS and KD test. Between-group comparisons for provocation scores on the VOMS (smooth pursuit, saccades, convergence, vestibular-ocular reflex [VOR], and visual motion sensitivity [VMS]), Near-point of convergence [NPC] average distance (cm), and KD time (seconds) were conducted.
Results
Individuals diagnosed with migraine headaches reported greater VOMS scores compared to match controls on smooth pursuit (0.43±1.1 vs. 0.00±0.0; p=.02), convergence (0.46±1.2 vs. 0.04±0.1; p=.04), horizontal VOR (0.89±1.4 vs. 0.07±0.2; p<.001), vertical VOR (0.61±1.1 vs. 0.11±0.3; p=.04), and VMS (0.86±1.5 vs. 0.04±0.1; p=.01). Differences were also observed on the KD test with worse times in the diagnosed migraine group (54.33±11.8s) compared to match controls (47.17±8.9s; p=.02). No differences were reported on NPC distance between the migraine (2.22±3.1cm) and control group (0.83±1.2; p=.06).
Conclusion
Youth athletes with diagnosed migraine history reported higher baseline VOMS scores and worse KD time compared to match controls, further illustrating the influence of premorbid migraine headaches as a risk factor for elevated baseline concussion assessment. Special consideration may be warranted for post-concussion assessment in athletes with diagnosed migraine headaches.

Abstract
A multi-energy soft x-ray pinhole camera has been designed and built for the Madison Symmetric Torus reversed field pinch to aid the study of particle and thermal-transport, as well as MHD stability physics. This novel imaging diagnostic technique combines the best features from both pulse-height-analysis and multi-foil methods employing a PILATUS3 x-ray detector in which the lower energy threshold for photon detection can be adjusted independently on each pixel. Further improvements implemented on the new cooled systems allow a maximum count rate of 10 MHz per pixel and sensitivity to the strong Al and Ar emission between 1.5 and 4 keV. The local x-ray emissivity will be measured in multiple energy ranges simultaneously, from which it is possible to infer 1D and 2D simultaneous profile measurements of core electron temperature and impurity density profiles with no a priori assumptions of plasma profiles, magnetic field reconstruction constraints, high-density limitations, or need of shot-to-shot reproducibility. The expected time and space resolutions will be 2 ms and <1 cm, respectively.

Abstract
We developed a GIS desktop model to accurately locate and map prospective areas for sustainable establishment and production of Atriplex plantations and other fodder shrubs in the desert in the north-eastern Jordanian Badiyah. The aim is to provide a tool to assist managers, local communities and development projects in Mediterranean arid and semi-arid rangelands. The model uses freely available data and GIS layers of current land use, land cover, settlement location, soil information, and derivatives from a digital elevation model to provide critical locations of drainage lines and to calculate Areas of Accumulated Water from concentrated runoff. The model identified, accurately located and mapped ~4500 ha (1.44% of the test zone) as technically appropriate for potential shrub plantations sites. The final site map must be field-checked and validated with the local communities and authorities. Our model has potential for wide application over arid and semi-arid Mediterranean rangelands from Morocco to Pakistan, with local adjustment of our parameters and rules. The model considerably reduces the risk and costs of fodder plantation establishment operations, thus increasing the feasibility of efforts to maximise fodder shrub establishment, survival and production.

Abstract
OBJECTIVE Although, child mental health problems are widespread, few get adequate treatment, and there is a severe shortage of child psychiatrists. To address this public health need many states have adopted collaborative care programs to assist primary care to better assess and manage pediatric mental health concerns. This report adds to the small literature on collaborative care programs and describes one large program that covers most of New York state. PROGRAM DESCRIPTION CAP PC, a component program of New York State's Office of Mental Health (OMH) Project TEACH, has provided education and consultation support to primary care providers covering most of New York state since 2010. The program is uniquely a five medical school collaboration with hubs at each that share one toll free number and work together to provide education and consultation support services to PCPs. METHODS The program developed a clinical communications record to track information about all consultations which forms the basis of much of this report. 2-week surveys following consultations, annual surveys, and pre- and post-educational program evaluations have also been used to measure the success of the program. RESULTS CAP PC has grown over the 6years of the program and has provided 8013 phone consultations to over 1500 PCPs. The program synergistically provided 17,523 CME credits of educational programming to 1200 PCPs. PCP users of the program report very high levels of satisfaction and self reported growth in confidence. CONCLUSIONS CAP PC demonstrates that large-scale collaborative consultation models for primary care are feasible to implement, popular with PCPs, and can be sustained. The program supports increased access to child mental health services in primary care and provides child psychiatric expertise for patients who would otherwise have none.

Abstract
Background China has the largest absolute number of people living with hepatitis B with up to 300,000 people estimated to die each year from hepatitis B related diseases. Despite advances in immunisation, clinical management, and health policy, there is still a lack of accessible and affordable health care for people with hepatitis B. Through in-depth interviews, this study identifies the personal, social and economic impact of living with hepatitis B and considers the role of stigma and discrimination as barriers to effective clinical management of the disease. Methods Semi-structured qualitative interviews were held with 41 people living with hepatitis B in five Chinese cities. Participants were recruited through clinical and non-government organisations providing services to people with hepatitis B, with most (n = 32) being under the age of 35 years. Results People living with hepatitis B experience the disease as a transformative intergenerational chronic infection with multiple personal and social impacts. These include education and employment choices, economic opportunities, and the development of intimate relationships. While regulations reducing access to employment and education for people with hepatitis B have been repealed, stigma and discrimination continue to marginalise people with hepatitis B. Conclusions Effective public policy to reduce morbidity and mortality associated with hepatitis B needs to address the lived impact of hepatitis B on families, employment and educational choices, finances, and social marginalisation.

Abstract
The aims of the study were to determine the effect of season and blanketing on vitamin D synthesis in horses and examine the interaction between vitamin D and other analytes involved in calcium homeostasis. Twenty-one healthy horses at pasture were included; 5 were covered with standard horse blankets including neck rugs. Blood samples were collected for 13 mo and analyzed for 25-hydroxyvitamin D2 (25OHD2) and 25-hydroxyvitamin D3 (25OHD3), 1,25-dihydroxyvitamin D (1,25[OH]2D), ionized calcium (iCa), total calcium (tCa), phosphorus (P), total magnesium (tMg), and parathyroid hormone (PTH). Grass and hay samples were collected and analyzed for vitamin D, calcium, phosphorus, and magnesium. Climate data were also collected. The serum concentration of 25OHD3 in horses was either undetectable or below the detection limit of the assay, and the main form of 25OHD was 25OHD2. No differences in serum 25OHD2, 1,25(OH)2D, iCa, tCa, P, tMg, and PTH (P ≥ 0.05) concentrations were seen between the 2 groups. Associations were seen between iCa and PTH (P < 0.05), iCa and tMg (P < 0.05), and dietary vitamin D and 25OHD2 (P < 0.05). A strong seasonal trend was seen in serum 25OHD2 (P < 0.0001), which was higher during spring and summer when the amount of sunshine and UV radiation was higher. Parathyroid hormone and 1,25(OH)2D showed opposing trends with PTH higher in winter whereas 1,25(OH)2D was higher in summer. The results suggest that dietary vitamin D may be necessary for horses to fulfill their vitamin D requirements; however, further research is required to determine the contribution of vitamin D3 synthesis in the skin to the vitamin D status of the horse.

Abstract
The spontaneous formation of magnetic islands is observed in driven, antiparallel magnetic reconnection on the Terrestrial Reconnection Experiment. We here provide direct experimental evidence that the plasmoid instability is active at the electron scale inside the ion diffusion region in a low collisional regime. The experiments show the island formation occurs at a smaller system size than predicted by extended magnetohydrodynamics or fully collisionless simulations. This more effective seeding of magnetic islands emphasizes their importance to reconnection in naturally occurring 3D plasmas.

Abstract
Genetic variation can affect drug response in multiple ways, although it remains unclear how rare genetic variants affect drug response. The electronic Medical Records and Genomics (eMERGE) Network, collaborating with the Pharmacogenomics Research Network, began eMERGE‐PGx, a targeted sequencing study to assess genetic variation in 82 pharmacogenes critical for implementation of “precision medicine.” The February 2015 eMERGE‐PGx data release includes sequence‐derived data from ∼5,000 clinical subjects. We present the variant frequency spectrum categorized by variant type, ancestry, and predicted function. We found 95.12% of genes have variants with a scaled Combined Annotation‐Dependent Depletion score above 20, and 96.19% of all samples had one or more Clinical Pharmacogenetics Implementation Consortium Level A actionable variants. These data highlight the distribution and scope of genetic variation in relevant pharmacogenes, identifying challenges associated with implementing clinical sequencing for drug treatment at a broader level, underscoring the importance for multifaceted research in the execution of precision medicine.

Abstract
An environmental radiation calibration facility has been constructed by the Radiation and Nuclear Sciences unit of Queensland Health at the Forensic and Scientific Services Coopers Plains campus in Brisbane. This facility consists of five low density concrete pads, spiked with a NORM source, to simulate soil and effectively provide a number of semi-infinite uniformly distributed sources for improved energy response calibrations of radiation equipment used in NORM measurements. The pads have been sealed with an environmental epoxy compound to restrict radon loss and so enhance the quality of secular equilibrium achieved. Monte Carlo models (MCNP),used to establish suitable design parameters and identify appropriate geometric correction factors linking the air kerma measured above these calibration pads to that predicted for an infinite plane using adjusted ICRU53 data, are discussed. Use of these correction factors as well as adjustments for cosmic radiation and the impact of surrounding low levels of NORM in the soil, allows for good agreement between the radiation fields predicted and measured above the pads at both 0.15 m and 1 m.
