Abstract
Background Predictive biomarkers for immune checkpoint blockade in the second-line treatment of metastatic renal cell carcinoma (mRCC) are lacking. Materials and methods Patients with histologically confirmed RCC who started nivolumab after at least 4 months of tyrosine kinase inhibitors (TKIs) were recruited for this study. Serial tissue and blood samples were collected for immune biomarker evaluation. The primary endpoint was to determine the association of specific T-cell subsets with clinical outcomes tested using Wilcoxon rank sum for clinical benefit rate (CBR) and log-rank test for progression-free survival (PFS). Results Twenty patients were included in this trial with a median age of 64 years and followed-up for a median of 12 months. The median PFS for patients who received TKI was 13.8 months, while for those subsequently treated with nivolumab following TKI therapy, the median PFS was 2.6 months. CBR of nivolumab was 20% with two partial responses. Functionally active programmed cell death protein 1+ CD4+ T cells were enriched in non-responders (q = 0.003) and associated with worse PFS on nivolumab (P = 0.04). Responders showed a significant reduction in the effector CD4+T-cell (TEF) fraction compared to non-responders at 3 months on nivolumab (0.40 versus 0.80, P = 0.0005). CD127+CD4+ T cells were enriched in patients who developed immune-related adverse effects (q = 0.003). Using in-house validated multiplex immunohistochemistry for six markers, we measured tumour-associated immune cell densities in tissue samples. Responders to nivolumab showed a significantly higher mean of immune cell densities in tissue samples compared to non-responders (346 versus 87 cells/mm2, P = 0.04). Conclusions In this small study, analysis of tissue-based and peripheral blood immune cell subsets predicted clinical outcomes of nivolumab. Further studies are warranted with larger populations to validate these observations.

Abstract
PURPOSE/OBJECTIVE(S) Our prior work demonstrated that inhibition of MAPKAPK2 (MK2) can enhance radiation (RT)-mediated in vivo head and neck squamous cell carcinoma (HNSCC) tumor control and survival in preclinical immune incompetent models. The cytosolic DNA sensor cyclic GMP-AMP synthetase (cGAS) and its downstream adaptor protein, stimulator of interferon genes (STING), are conserved proteins within the innate immune signaling pathways and are important for mediating host defense against microbial infection and can play a role in anti-cancer immunity. We hypothesized that loss of MK2 enhances radiation-induced cGAS-STING pathway activation leading to improved tumor control and survival. MATERIALS/METHODS MK2 shRNA knockdown human (Tu167, CAL27) and MK2 Cas9/CRISPR knockout (KO) syngeneic murine (Ly2, MLM3) HNSCC cell lines were treated with 10 Gy irradiation. Micronuclei were quantitated by DAPI-immunofluorescence (IF). Protein changes in cGAS-STING were evaluated by immunoblot. Inflammatory cytokine production including Type I IFNβ1 were evaluated by RT-qPCR. Ly2 and MLM3 cells were orthotopically or flank engrafted into immune competent mice (Balb/c, C57Bl/6, respectively) for animal tumor control-survival studies. Tumor immune cell infiltrate was examined using FACS and immunohistochemistry. Selected drug studies using the MK2 inhibitor, ATI-450, were performed with RT. RESULTS Loss of MK2 in HNSCC (Tu167, CAL27, Ly2, MLM3) treated with RT led to a significant increase in micronuclei formation compared to control cells. MK2-enhanced micronuclei generation following RT could be inhibited with the actin filament polymerization inhibitor, cytochalasin B. RT treatment of MK2 shRNA cells led to increased cGAS and phospho-STING levels compared to either treatment alone. IFNβ1 levels were significantly higher in HNSCC cell lines treated with RT and with MK2 inhibited by an MK2 inhibitor (ATI-450) or genetic reduction compared to either treatment alone. In-vivo implantation of MLM3 cells into C57Bl/6 comparing control vs MK2 KO tumors treated with ±8 Gy RT demonstrated improved mouse survival favoring RT+MK2 KO over RT, MK2 KO or parental (63, 58, 58.5, 35 days, respectively). FACS analysis of MLM3 WT v KO tumors 3 days post RT showed an overall increase in the number of CD3/CD8 T-cells infiltrating into the tumor in all groups except for parental tumors. Further analysis demonstrated that loss of MK2 reversed CD8 T-cell exhaustion and when combined with radiotherapy led to increased CD8 T-cell activation. Furthermore, activated CD4 and CD8 T cells were reduced in WT+RT cells compared to WT tumors whereas no reduction was seen in the KO or KO+RT. CONCLUSION HNSCC tumor MK2 inhibition enhances RT-mediated micronuclei formation and subsequent cGAS-STING-IFNβ1 levels. Loss of HNSCC MK2 leads to increased CD4-CD8 T-cell infiltration into the tumor and this effect is enhanced following RT. Targeting tumor MK2 may facilitate improved tumor control.

Abstract
Introduction Residential aged care (RAC) represents a fast-growing sector within Australia's health care system and is characterized by high levels of workplace injury. To better understand this injury problem, this study investigated key informant perspectives concerning sector occupational health and safety (OHS) focused on key issues associated with the risk of worker injury. Method Semi-structured interviews were undertaken with nine key informants representing (OHS) specialists, healthcare employers, regulators, worker association representatives, and academic researchers in OHS or healthcare. Interviews were transcribed verbatim and analyzed using thematic analysis. Results This study identified six themes on OHS within RAC including (i) the physical and emotional nature of the work, (ii) casualization of employment, (iii) prioritization, (iv) workforce profile, (v) OHS role construction, and (vi) clinical standards. The study highlighted differences in OHS roles between RAC and other safety-critical sectors regarding governance and management of OHS. The key informants identified a propensity within RAC to downplay or disregard worker OHS issues justified through prioritizing resident safety. Further, neither OHS professional nor institutional logics are prominent in RAC leadership and decision-making where the emphasis is placed on mandatory standards to maintain funding purposes. Several recommendations are made to address identified issues.

Abstract
A range of organisations in English-speaking countries have prepared guidance materials for individuals who are facing concerns regarding dementia while employed. Some of these organisations have also prepared guidance materials for employers to assist them in engaging employees facing this condition. These are available on organisation websites and may be presented as a downloadable booklet, guide or one or more web pages, aiming to inform about the issues that need to be considered. Information of this type is becoming more important in assisting both parties as dementia is being detected and diagnosed earlier, and individuals need to consider their options regarding their future and their ability to continue to work. This presentation reports on a systematic analysis of around guidance items appearing on these websites. The topic areas, content, and approaches used to present this information to its intended audience were reviewed and compared. Analysis showed important gaps in content coverage from one guidance to another. No guidance presented by any of these organisations covers all areas identified that may potentially interest either employees or employers and in most cases it is not presented coherently for these groups. Employee topics that would benefit from further development include awareness of the condition, the importance of diagnosis and support, use of technology to assist in continuing to be functional and productive, and steps in transition from work to other activities. Employer topics that could be developed further include building awareness amongst employers and the workforce, identifying dementia in the workplace, engaging the wider work group, and positively managing employee separation from work.

Abstract
ISSUE ADDRESSED Participants engaged in rock fishing are at risk of drowning. Following coronial investigation of fatalities, a 3-year safety campaign targeting rock fishers was developed in Victoria, Australia. Key campaign messages were wearing lifejackets, not fishing alone, and checking sea and weather conditions. The reported study provides results from a campaign evaluation. METHODS Evaluation by self-report and direct observation of safety attitudes and behaviours was undertaken pre- and during campaign. Data collections were as follows: (a) online survey of rock fishers recruited from panels, social media and rock fishing networks (n = 350) and (b) rock fisher direct observation and self-report at selected Victorian rock fishing platforms (n = 282; n = 58, respectively). RESULTS Safety message recall was reported by 51.7% of rock fishers surveyed online though far fewer recalled campaign key messages. No effect on key safety behaviours or attitudes were detected for fishers on platforms during campaign. Never wearing a lifejacket was reported by 31.8% online, 60.3% at platforms and observed for 97.4%. From direct observation, most participants did not fish alone and checked conditions on arrival. CONCLUSION Campaign evaluation measures showed mixed outcomes. Irrespective, most rock fishers carry high drowning risk through failure to wear lifejackets. Legal mandating of lifejackets for identified high-risk platform is being introduced for Victoria, although careful evaluation is required to detect unanticipated outcomes. Informing future campaign evaluation, complementary methods highlight likely bias in self-reporting through faulty recall or social desirability. SO WHAT?: Future campaigns require innovative or novel design, over longer duration, to capture attention and change rock fisher behaviours.

Abstract
Younger Onset Dementia (YOD) and Mild Cognitive Impairment (MCI) are relatively prevalent conditions globally which can affect the job performance of individuals in their working lives. This presentation considers the existing research documenting actual, stated or intended approaches taken by employers to managing and supporting employees with these conditions. Nine relevant research projects were identified based on an extensive exploration of the peer reviewed literature. These show that employers have some knowledge of dementia, but do not recognise this as a possible explanation when performance changes occur in the workplace. Employees typically leave or are removed from the workplace before a formal diagnosis or soon after. The literature shows both supportive and unsupportive behaviours toward employees. Drawing from this literature recommendations for increasing the quality of support provided to employees are offered: awareness training to foster earlier detection, clarification of these conditions as a disability, and application of methods to support employees to continue to contribute to the workplace while this is feasible and desirable from both the employer and the employee’s perspective.

Abstract
Introduction The COVID-19 pandemic has delivered significant challenges to the Orthopaedic community. Our study aims to assess the impact of COVID-19 on the management and outcomes of patient’s presenting with Hip Fractures to our DGH. Method Retrospective data analysis was performed on a cohort of hip fracture patients who presented to our DGH before the COVID-19 pandemic (23/03/2019 to 05/05/2019) and were compared to those who presented during the COVID-19 pandemic (23/03/2020 to 05/05/2020). Minimum follow up was 30 days postoperatively. Results 38 patients with hip fractures presented to our unit in the pre-COVID-19 period compared to 27 patients in the COVID-19 period. Total time from presentation to discharge, during COVID-19, demonstrated a 70.23% decrease when compared to the pre-COVID cohort. 30-day Mortality rates were higher in the COVID-19 cohort. Conclusions During the COVID-19 pandemic our time to theatre and discharge of hip fractures has seen an improvement, with time to discharge decreasing by 70.23%. Comparison of our mortality rates has seen a fourfold increase likely influenced by the detrimental effects of COVID-19. Further work and larger numbers are required to see the true impact of COVID-19 on the management and outcomes of hip fractures in our DGH.

Abstract
Costs of large predator conservation may not be equitably distributed among stakeholders; these include farming communities, tourism business owners and visitors. Financial redistribution mechanisms based on accrued benefits and costs of conservation require relevant data unavailable in many locations. To address this, a contingent valuation method identified willingness to pay (WTP) among national park visitors and connected tourism business owners. Both groups derive benefit from government-funded conservation policies. The study was conducted in Bardia and Chitwan National Parks, Nepal 2017-2018; two locations world-renowned for tiger conservation. Local and international park visitors (N = 387) provided WTP for ongoing conservation via additional park entry fees. Tourism business owners (TBOs; N = 74) proximate to the parks stated their WTP for compensation funding provided directly to farmers. The majority (65%) of park visitors were willing to pay extra to support conservation (sample mean US$ 20) while 85 percent of TBOs supported their payment of funds for compensating farming communities (sample mean annual contribution being US$ 156). Valid WTP regression modelling found that visitor WTP was predicted by international travel costsand environmental organization affiliation. For TBOs indicating WTP, the amount to pay was predicted by annual net income from the tourism business. Application of study data indicates US$ 25 average increase to visitor park fees would maximise revenue and contribute a further US$ 495,000 available for conservation activities. Similarly, a flat-rate tariff on TBOs at the mean WTP amount would contribute more than double the annual budget available for farmer compensation (providing approximately US$ 43,000). More generally, the study findings are informative for policy-makers seeking equitable conservation outcomes while maintaining viable populations of critically endangered wild tigers. They should however be interpreted with caution given limitations of the sampling frame and method of data elicitation. Regardless, any policy decision effects require careful scrutiny to ensure desired outcomes are realized.

Abstract
OBJECTIVE Phosphorylation of insulin receptor substrate (IRS) 1 by tumor necrosis factor alpha (TNF-α) has been implicated as a factor contributing to insulin resistance. Administration of IL-15 reduces adipose tissue deposition in young rats and stimulates secretion of adiponectin, an insulin sensitizing hormone that inhibits the production and activity of TNF-α. We aimed at investigating the effects of age life-long moderate calorie restriction (CR) on IL-15 and TNF-α signaling in rat white adipose tissue (WAT). MATERIALS AND METHODS Thirty-six 8-month-old, 18-month-old, and 29-month-old male Fischer344´Brown Norway F1 rats (6 per group) were either fed ad libitum (AL) or calorie restricted by 40%. The serum levels of IL-15 and IL-15 receptor α-chain (IL-15Rα) were increased by CR controls regardless of age. An opposite pattern was detected in WAT. In addition, CR reduced gene expression of TNF-α and cytosolic IRS1 serine phosphorylation in WAT, independently from age. RESULTS IL-15 signaling in WAT is increased over the course of aging in AL rats compared with CR rodents. Protein levels of IL-15Rα are greater in WAT of AL than in CR rats independently from age. This adaptation was paralleled by increased IRS1 phosphorylation through TNF-α-mediated insulin resistance. Adiponectin decreased at old age in AL rats, while no changes were evident in CR rats across age groups. CONCLUSIONS IL-15 signaling could therefore represent a potential target for interventions to counteract metabolic alterations and the deterioration of body composition during aging.

Abstract
STUDY QUESTION Do human oocytes express voltage-gated proton channels? SUMMARY ANSWER Human oocytes exhibit voltage-gated proton currents. WHAT IS KNOWN ALREADY Voltage-gated proton currents have been reported in human sperm, where they contribute to capacitation and motility. No such studies of human oocytes exist. STUDY DESIGN, SIZE, DURATION Voltage-clamp studies were undertaken using entire oocytes and vesicles derived from oocytes and in excised patches of membrane from oocytes. PARTICIPANTS/MATERIALS, SETTING, METHODS Frozen, thawed human metaphase II oocytes were obtained from material donated to the gamete repository at the Rush Center for Advanced Reproductive Care. Prior to patch clamping, oocytes were warmed and equilibrated. Formation of an electrically tight seal requires exposing bare oolemma. Sections of the zona pellucida (ZP) were removed using a laser, followed by repeated pipetting, to further separate the oocyte from the ZP. Patch-clamp studies were performed using the whole-cell configuration on oocytes or vesicles derived from oocytes, and using inside-out patches of membrane, under conditions optimized to detect voltage-gated proton currents. MAIN RESULTS AND THE ROLE OF CHANCE Proton currents are present at significant levels in human oocytes where they exhibit properties similar to those reported in other human cells, as well as those in heterologous expression systems transfected with the HVCN1 gene that codes for the voltage-gated proton channel. LARGE SCALE DATA N/A. LIMITATIONS, REASONS FOR CAUTION Human oocytes are large cells, which limits our ability to control the intracellular solution. Subtle effects of cryopreservation by vitrification and subsequent warming on properties of HVCN1, the HVCN1 gene product, cannot be ruled out. WIDER IMPLICATIONS OF THE FINDINGS Possible functions for voltage-gated proton channels in human oocytes may now be contemplated.

Abstract
OBJECTIVES Cricket is a popular sport enjoyed worldwide. Injuries in cricket are not well understood at community level but are important to understand for prevention to ensure the game continues to be enjoyed safely. This systematic review was designed to assess the quality of data collection and reporting, and to summarise the injury data, in studies of community cricket players. DESIGN Systematic review. METHODS Nine databases were searched to November 2018 using the terms "cricket*" and "injur*". A nine-item critical appraisal and three-item likelihood-of-bias evaluation was conducted on included studies. Data completeness was evaluated against recommendations in the international cricket consensus statement for recording/reporting injury and the Australian Sports Injury Data Dictionary (ASIDD). Descriptive injury data (n,%) are presented in tabular format for different subgroups (activity, position, population). RESULTS Thirteen studies were included, of which eight were rated as unclear, one as high and three having a low likelihood-of-bias. The mean score for completeness of data against the consensus statement was 3.5/10 (95%C.I. 2.8-4.2). The mean score for completeness of data against the ASIDD was 4.4/6 (95%C.I. 3.9-5.0). Bruising and inflammation was the most common injury in junior cricket. Stress fractures were most common in studies of bowlers. Where studies included all activities, batting accounted for most injuries (7-49%). CONCLUSIONS The included studies inconsistently addressed recommended items for injury surveillance in community sport and cricket. Most studies focused on junior levels or adolescent bowlers, with bruising/inflammation and stress fractures being most common, respectively.

Abstract
Objectives The aim was to identify and describe outcomes from original published studies that present the number, nature, mechanism and severity of medically treated injuries sustained in community-level cricket. Design Systematic review. Methods Nine databases were systematically searched to December 2019 using terms "cricket*" and "injur*". Original, peer-reviewed studies reporting injury for at least one injury descriptor (body region, nature of injury and/or mechanism of injury) in community-level cricketers of all ages were included. Qualitative synthesis, critical appraisal and descriptive summary results are reported within the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Results Six studies were included: five reported hospital-treated data and one reported insurance claims data. Two had a low risk of bias. In hospital-based studies, fractures were the most frequent injury type. Upper and lower limb injuries (age ≥15 years) and injuries to the head (age <15 years) were the most common body region injured. Being struck by the ball was the most common mechanism for injury presenting to hospitals. Children were also commonly struck by equipment. One study using insurance claims data reported soft tissue injuries as the main of injury type. Conclusion Hospital treatment data were most prominent, which emphasised injuries of a more serious nature or requiring acute care. These injuries were primarily fractures, dislocation/sprain and strains, bruising and open wounds with the majority resulting from players being struck by the ball. Research into whether properly fitted protective equipment, at an approved standard, is worn and is effective, is recommended.

Abstract
Abstract
Background
Life expectancy improvements have slowed down in several European countries since around 2011. The relative contributions from changes in specific conditions (e.g. cancers) and broader risk factors (e.g. smoking or austerity) remain unclear. We aimed to explore the different potential causes in 17 European Economic Area (EEA) countries.
Methods
We compared Global Burden of Disease (GBD) study estimates for life expectancy, years of life lost (YLLs) and population attributable fractions (PAFs) for risk factors, for 2005-2011 and 2011-2017 for 17 EEA countries. Three countries with the largest absolute improvements and three with the smallest were selected for analysis by gender, age, condition and risk factors.
Results
Norway, France and Belgium had the largest improvement in life expectancy (+1.5, +1.2 and +1.2 years respectively) from 2011 to 2017, and Germany, Iceland and the UK the smallest (+0.1, +0.2 and +0.2 years). Life expectancy reduced slightly for women aged over 80 in Germany and UK, men aged over 50 in Germany, and for men in all age groups up to 90 years in Iceland. Norway, France and Belgium saw faster improvements in YLLs from lung cancer and Norway and France for COPD in both men and women, and from self-harm in men, after 2011 than before. PAF for tobacco declined faster after 2011. Germany, Iceland and the UK saw slower improvements in cardiovascular disease and in Germany and the UK lung cancer. In Iceland, YLLs for cancers, self harm, respiratory disease, cirrhosis and dementia all worsened after 2011. PAF for tobacco remained high or declined less after 2011 in all 3 countries. PAFs for alcohol and drug use remained high in Iceland and UK.
Conclusions
Differential changes in major fatal diseases and risk factors help explain national changes in life expectancies, but national differences in data availability may affect results. Further research is needed into the ‘causes of the causes’, such as the 2008 economic crash in Iceland.
Key messages
Differential changes in major fatal diseases and risk factors help explain national changes in life expectancies. Norway, France and Belgium had the largest improvement in life expectancy from 2011 to 2017, and Germany, Iceland and the UK the smallest.

Abstract
Robust epidemiological studies identifying determinants of negative health outcomes require significant research effort. Expert judgement is proposed as an efficient alternative or preliminary research design for risk factor identification associated with unintentional injury. This proposition was tested in a multi-factorial balanced experimental design using specialist judges (N = 18), lifeguards and surfers, to assess the risk contribution to drowning for swimming ability, surf bathing experience, and wave height. All factors provided unique contributions to drowning risk (p < .001). An interaction (p = .02) indicated that occasional surf bathers face a proportionally increased risk of drowning at increased wave heights relative to experienced surf bathers. Although findings were limited by strict criteria, and no gold standard comparison data were available, the study provides new evidence on causal risk factors for a drowning scenario. Countermeasures based on these factors are proposed. Further application of the method may assist in developing new interventions to reduce unintentional injury.

Abstract
Abnormal tau hyperphosphorylation and its aggregation into neurofibrillary tangles are a hallmark of tauopathies, neurodegenerative disorders that include Alzheimer's disease (AD). Active and passive Tau-immunotherapy has been proposed as a therapeutic approach to AD with mixed results. One of the limitations of active immunotherapy may be associated with the mediocre immunogenicity of vaccines that are not inducing therapeutically potent titers of antibodies. The aim of this study was to test the efficacy of an anti-tau vaccine, AV-1980R/A composed of N terminal peptide of this molecule fused with an immunogenic MultiTEP platform and formulated in a strong adjuvant, AdvaxCpG in a Tg4510 mouse model of tauopathy. Experimental mice were immunized with AV-1980R/A and a control group of mice were injected with adjuvant only. Nontransgenic and tetracycline transactivator (tTA) transgenic littermates were included as baseline controls to contrast with the tau phenotype. Active immunization with AV-1980R/A induced very strong anti-tau humoral immune responses in both nontransgenic and transgenic mice with evidence of IgG in brains of AV-1980R/A vaccinated mice. These experimental animals displayed an improvement in short-term memory during a novel object recognition test. However, impairments in other behavioral tasks were not prevented by AV-1980R/A vaccinations. At the same time, high titers of anti-tau antibodies reduced hyperphosphorylated pSer396 tau but did not lower the level of other phosphorylated tau species in the brains of AV-1980R/A vaccinated mice. These data indicate that active immunotherapy with an N-terminal Tau epitope was only partially effective in improving cognition and reducing pathology in the stringent Tg4510 mouse model of tauopathy.

Abstract
The spread of the Zika virus (ZIKV) in the Americas led to large outbreaks across the region and most of the Southern hemisphere. Of greatest concern were complications following acute infection during pregnancy. At the beginning of the outbreak, the risk to unborn babies and their clinical presentation was unclear. This report describes the methods and results of the UK surveillance response to assess the risk of ZIKV to children born to returning travellers. Established surveillance systems operating within the UK - the paediatric and obstetric surveillance units for rare diseases, and national laboratory monitoring - enabled rapid assessment of this emerging public health threat. A combined total of 11 women experiencing adverse pregnancy outcomes after possible ZIKV exposure were reported by the three surveillance systems; five miscarriages, two intrauterine deaths and four children with clinical presentations potentially associated with ZIKV infection. Sixteen women were diagnosed with ZIKV during pregnancy in the UK. Amongst the offspring of these women, there was unequivocal laboratory evidence of infection in only one child. In the UK, the number and risk of congenital ZIKV infection for travellers returning from ZIKV-affected countries is very small.

Abstract
PURPOSE In 1959, Maroteaux and Lamy initially designated pseudoachondroplasia as a distinct dysplasia different from achondroplasia the most common form of skeletal dysplasia. Pseudoachondroplasia is caused by a mutation in the collagen oligomeric matrix protein gene (COMP) gene on chromosome 19p13.1-p12 encoding the COMP. The COMP gene mutations result in rendering the articular and growth plate cartilages incapable of withstanding routine biomechanical loads with resultant deformity of the joints. The purpose of the study was to characterize the typical orthopaedic findings in pseudoachondroplasia. METHODS The charts and radiographs of 141 patients with pseudoachondroplasia were analyzed. This cohort, to our knowledge, represents the largest group of patients describing the typical orthopaedic manifestations of pseudoachondroplasia. RESULTS Patients with pseudoachondroplasia have normal craniofacial appearance with normal intelligence. Short stature is not present at birth and generally appears by two to four years of age. The condition is a form of spondyloepiphyseal dysplasia and the long bones are characterized by dysplastic changes in the epiphysis, metaphysis and vertebral bodies. Radiographically the long bones have altered the appearance and structure of the epiphyses with small irregularly formed or fragmented epiphyses or flattening. The metaphyseal regions of the long bones show flaring, widening or 'trumpeting'. The cervical (89%) and thoracic and lumbar vertebrae show either platyspondyly, ovoid, 'cod-fish' deformity or anterior 'beaking'. Kyphosis (28%), scoliosis (58%) and lumbar lordosis (100%) are commonly seen. The femoral head and acetabulum are severely dysplastic (100%). The knees show either genu valgum (22%), genu varum (56%) or 'windswept' deformity (22%). CONCLUSION Most commonly these distortions of the appendicular and the axial skeleton lead to premature arthritis particularly of the hips and often the knees not uncommonly in the 20- to 30-year-old age group.

Abstract
In this study, the involvement of aluminum-based drinking water treatment residual (DWTR) as substrate in floating treatment wetland (FTW) to enhance its treatment performance was firstly proposed and trialed. A laboratory scale DWTR-FTW fed with synthetic wastewater containing COD, nitrogen (N), phosphorus (P) and mineral salts was operated in three stages of unplanted (1-30 days), planted (31-60 days) and aerated (61-135 days) modes. The results showed that the average removal rates of COD, total nitrogen (TN), total phosphorus (TP) in stage 3 were 88%, 85%, and 90.2%, respectively, indicating the outstanding purification performance of DWTR-FTW in comparison of traditional FTWs. The embedded DWTR enriches the biomass and robustly adsorbs P, while aeration supplies sufficient dissolved oxygen for the microorganism. The results revealed that 7.022 g P was accumulated in DWTR, which is 400 times higher than that in sediment and plants during the experimental period, reflecting that DWTR adsorption is the major P removal pathway in DWTR-FTW. Overall, DWTR-FTW could significantly remove pollutants, especially P, and provide an alternative pathway to enhance purification performance of FTW.

Abstract
Atom probe tomography (APT) and scanning transmission electron microscopy (STEM) techniques were used to probe the long-time thermal stability of nm-scale Mn-Ni-Si precipitates (MNSPs) formed in intermediate and high Ni reactor pressure vessel steels under high fluence neutron irradiation at ≈320 °C. Post irradiation annealing (PIA) at 425 °C for up to 57 weeks was used to determine if the MNSPs are: (a) non-equilibrium solute clusters formed and sustained by radiation induced segregation (RIS); or, (b) equilibrium G or Γ2 phases, that precipitate at accelerated rates due to radiation enhanced diffusion (RED). Note the latter is consistent with both thermodynamic models and x-ray diffraction (XRD) measurements. Both the experimental and an independently calibrated cluster dynamics (CD) model results show that the stability of the MNSPs is very sensitive to the alloy Ni and, to a lesser extent, Mn content. Thus, a small fraction of the largest MNSPs in the high Ni steel persist, and begin to coarsen at long times. These results suggest that the MNSPs remain a stable phase, even at 105 °C higher than they formed at, thus are most certainly equilibrium phases at much lower service relevant temperatures of ≈290 °C.

Abstract
Objective There is a growing focus on ensuring the availability of automated external defibrillators (AED) in sport settings to assist in preventing sudden cardiac death. For the AED to be most effective, understanding how best to integrate it with wider risk management and emergency action plans (EAP) is needed. The aim of this survey was to identify sports club/facility member knowledge of AED use and club EAPs, 6 months following participation in a government-funded AED provision and cardiopulmonary resuscitation training programme. Methods Cross-sectional survey of community sports clubs and facilities in Victoria, Australia. Included participants were members of sports club/facilities that had been provided with an AED and basic first aid training as part of a government programme to increase access to, and awareness of, AEDs. A descriptive analysis of availability of EAPs and AEDs, together with practical scenarios on AED use and maintenance, is presented. Results From 191 respondents, more than half (56%) had no previous training in AED use. Knowledge on availability of an EAP at the club/facility was varied: 53% said yes and knew where it was located, while 41% did not have, or did not know if they had, an EAP. Responses to clinical scenarios for use of AED were mostly accurate, with the exception of being unsure how to respond when ‘a participant falls to the ground and is making shaking movements.’ Conclusions While there were positive outcomes from this programme, such as half of the respondents being newly trained in emergency first aid response, further improvements are required to assist members with embedding their AED into their club/facility EAP and practices.

Abstract
Osteonecrosis of the jaw (ONJ) is a rare, but severe, condition that has traditionally been associated with the use of bisphosphonates. We report what is, to our knowledge, the first case of ONJ secondary to the use of everolimus, in the absence of treatment with bisphosphonates in a 65-year-old man who was given it for immunosuppression after a renal transplant. After 18 months of treatment, he was diagnosed with severe ONJ and underwent radical debridement of the palate and complete dental clearance of the maxilla.

Abstract
Introduction This paper describes the funding rates established in Ontario to reflect best practices in hospital-based care delivery for these endoscopic procedures: colonoscopy, colonoscopy biopsy, gastroscopy, gastroscopy biopsy, and colonoscopy combined with gastroscopy. Methods The funding rates are based on direct costs and were established using a micro-costing approach after receipt of inputs from 3 working groups and a review of the administrative data and literature, where applicable. The first group advised on nursing activities, time, and staffing ratios along the patient pathway for each of the procedures. The second group provided recommendations about the duration for each procedure, and the third group provided information about supplies and equipment, their use, and costs. Results The resulting funding rates are $161.18 for colonoscopy and $151.08 for gastroscopy (without accompanying interventions), $16.06 for colonoscopy biopsy and $8.22 for gastroscopy biopsy (added to the respective procedures), and $207.26 for combined colonoscopy and gastroscopy. Detailed costs for each component embedded in the rates are also provided. Conclusions The rates came into effect in April 2018. The process and outcomes described here allowed for a transparent pricing mechanism in which funding follows the patient, clinical expert consensus is the basis for practice, and providers and payers both understand the components.
