Abstract
PURPOSE/OBJECTIVE(S) Despite efforts to increase participation of diverse communities in clinical trials, ethnic/racial minorities remain underrepresented. One such determinant may be lack of access to a comprehensive cancer center that conducts clinical research. Historically, our institution has had low accrual from rural regions further away from our cancer center, with Hispanic or Latino (HL) patients (pts) being especially underrepresented in our clinical research. In this study, we explored the impact of a clinical trial that allowed pts to receive chemotherapy (chemo) with their local oncologist. We hypothesize that allowing pts to receive chemo locally will lead to higher rates of enrollment from populations under-represented in clinical trials. MATERIALS/METHODS We conducted a study for pts with rectal cancer to undergo short-course radiation followed by 4 months of chemo with the option to pursue watch and wait if pts achieve a clinical complete response. Radiation was administered at our institution while pts could receive standard-of-care chemo closer to home with their local oncologist. For pts who received chemo locally, the research coordinator and co-investigators held video visits with the pts prior to each chemo infusion to review adverse events (AE), labs, and chemo dosing. We compared demographic data of pts on this trial with that of pts enrolled across all adult therapeutic oncologic clinical trials over the same time period at our institution. Distance to our institution was calculated based on pts' primary residence zip code. Protocol compliance with AE reporting for pts who received chemo locally was assessed by chart review. RESULTS Between May 2020 and January 2023, 24/35 enrolled pts completed both radiation and chemo on trial. 13/24 pts (54%) received chemo locally. Of the 24 pts, 16 were White (67%), 7 Asian (29%), 1 Native Hawaiian/ Pacific Islander (4%). Of all enrolled patients, 4 were HL (16.7%), compared to our institutional average of 16.5%. All enrolled HL pts received their chemo locally. The average distance traveled by non-HL pts from their home to our institution was 87.7 miles (range 5.1 - 308). In contrast, HL pts traveled an average of 147.8 miles (range 110 - 249), 68% further than their non-HL counterparts. There was 100% compliance with AE reporting among those pts who received their chemo locally. CONCLUSION Although the percentage of HL participation in our study was consistent with our institutional average, all HL pts enrolled on the trial received treatment locally and lived substantially further from our institution than non-HL. By allowing pts to receive this part of treatment locally, we provided pts who live further away an opportunity to engage in clinical research without the associated financial and time toxicities related with traveling for treatment. By decentralizing clinical trials and leveraging telemedicine, we can promote the participation of under-represented groups in clinical trials.

Abstract
PURPOSE/OBJECTIVE(S) Synchronous prostate and rectal cancer is rare and guidelines for co-management are not well established. This case series explores the prevalence of synchronous diagnosis and different treatment paradigms to propose a standardized approach to management. MATERIALS/METHODS We retrospectively reviewed all radiation treatments between 1/2017 and 12/2022 for curative intent treatment to both prostate and rectal cancer. Synchronous was defined as rectal or prostate cancer diagnosed within a 6-month period of each other. We collected baseline characteristics and treatment paradigms including the sequencing of chemoradiation (CRT), chemotherapy (CT), prostate boost, and surgery. RESULTS There were 10 out of 2204 total treated patients with prostate or rectal primary noted to have a synchronous diagnosis (0.45%). Table 1 shows characteristics and treatment approach for all patients with 50% receiving CRT and 50% CT alone first. At a median FU of 21.4 months, 2 patients did not complete therapy due to patient choice and both had progression of disease (POD). After completion of CRT, 6 patients underwent rectal surgery with 2 pathological complete response, and 2 patients proceeded with a Watch and Wait approach with clinical complete response on MRI. Prostate boost was delivered equally as often pre-surgery as post-surgery with both SBRT, EBRT and Seed Implant used. There was no grade 3+ RT related toxicity in the patients who completed all therapy. CONCLUSION This series represents one of the largest synchronous prostate and rectal cancer cohorts treated with curative intent. Future collaborative work is needed to develop guidelines in the treatment of synchronous prostate and rectal cancers. Although a rare diagnosis, the heterogeneity of approaches has led us to propose a standardized approach to management of synchronous diagnosis with upfront chemotherapy followed by EBRT inclusive of prostate and rectum followed by boost via brachytherapy (SBRT in non-candidates).

Abstract
OBJECTIVE Menopausal vasomotor symptoms commonly disrupt sleep and affect daytime productivity. This online survey evaluated associations between vasomotor symptom severity and perceived sleep quality and work productivity. METHODS Participants were perimenopausal or postmenopausal US women aged 40 to 65 years with ≥14 vasomotor symptom episodes per week for ≥1 week in the past month. The women, who were recruited from Dynata panels via email invitation and categorized by vasomotor symptom severity based on the Menopause Rating Scale, were surveyed about sleep and work productivity and completed the Patient-Reported Outcomes Measurement Information System Sleep Disturbance Short Form 8b (primary outcome) and Sleep-Related Impairment Short Form 8a, Pittsburgh Sleep Quality Index, and Work Productivity and Activity Impairment questionnaire. RESULTS Among 619 respondents (mean age, 53 y; White, 91%; perimenopausal, 34%; postmenopausal, 66%; 57.5% were never treated for vasomotor symptoms), vasomotor symptoms were mild in 88, moderate in 266, and severe in 265. A majority (58% overall) were employed, including 64.8%, 49.6%, and 64.2% of women with mild, moderate, and severe VMS, respectively. Of the 90.8% who reported that vasomotor symptoms affect sleep (81.8%, 86.8%, and 97.7% of those with mild, moderate, and severe VMS), 83.1% reported sleep-related changes in productivity (75.0%, 73.2%, and 94.2%, respectively). Patient-Reported Outcomes Measurement Information System Sleep Disturbance Short Form 8b mean T scores in the mild (T score, 53.5), moderate (57.3), and severe (59.8) VMS cohorts indicated more sleep disturbance than in the general population (T score, 50; overall P < 0.001 before and after controlling for confounding variables). Sleep-Related Impairment 8a results were similar. Vasomotor symptom severity was positively associated with Pittsburgh Sleep Quality Index mean scores, presenteeism, absenteeism, overall work impairment, and impairment in general activities. CONCLUSIONS Greater vasomotor symptom severity was associated with more sleep disturbance, more sleep-related impairment, worse sleep quality, and greater impairment in daytime activities and work productivity.

Abstract
A new deuterium-tritium experimental, DTE2, campaign has been conducted at the Joint European Torus (JET) between August 2021 and late December 2021. Motivated by significant enhancements in the past decade at JET, such as the ITER-like wall and enhanced auxiliary heating power, the campaign achieved a new fusion energy world record and performed a broad range of fundamental experiments to inform ITER physics scenarios and operations. New capabilities in the area of fusion product measurements by nuclear diagnostics were available as a result of a decade long enhancement program. These have been tested for the first time in DTE2 and a concise overview is provided here. Confined alpha particle measurements by gamma-ray spectroscopy were successfully demonstrated, albeit with limitations at neutron rates higher than some 1017 n/s. High resolution neutron spectroscopy measurements with the magnetic proton recoil instrument were complemented by novel data from a set of synthetic diamond detectors, which enabled studies of the supra-thermal contributions to the neutron emission. In the area of escaping fast ion diagnostics, a lost fast ion detector and a set of Faraday cups made it possible to determine information on the velocity space and poloidal distribution of the lost alpha particles for the first time. This extensive set of data provides unique information for fundamental physics studies and validation of the numerical models, which are key to inform the physics and scenarios of ITER.

Abstract
The ratio of the nucleon F_{2} structure functions, F_{2}^{n}/F_{2}^{p}, is determined by the MARATHON experiment from measurements of deep inelastic scattering of electrons from ^{3}H and ^{3}He nuclei. The experiment was performed in the Hall A Facility of Jefferson Lab using two high-resolution spectrometers for electron detection, and a cryogenic target system which included a low-activity tritium cell. The data analysis used a novel technique exploiting the mirror symmetry of the two nuclei, which essentially eliminates many theoretical uncertainties in the extraction of the ratio. The results, which cover the Bjorken scaling variable range 0.19<x<0.83, represent a significant improvement compared to previous SLAC and Jefferson Lab measurements for the ratio. They are compared to recent theoretical calculations and empirical determinations of the F_{2}^{n}/F_{2}^{p} ratio.

Abstract
Objectives Eye tracking has been gaining increasing attention as a possible assessment and monitoring tool for concussion. The King-Devick test (K-DT) was expanded to include an infrared video-oculography-based eye tracker (K-D ET). Therefore, the aim was to provide evidence on the reliability of the K-D ET system under an exercise condition. Methods Participants (N = 61; 26 male, 35 female; age range 19-25) were allocated to an exercise or sedentary group. Both groups completed a baseline K-D ET measurement and then either two 10-min exercise or sedentary interventions with repeated K-D ET measurements between interventions. Results The test-retest reliability of the K-D ET ranged from good to excellent for the different variables measured. The mean ± SD of the differences for the total number of saccades was 1.04 ± 4.01 and there was an observable difference (p = 0.005) in the trial number. There were no observable differences for the intervention (p = 0.768), gender (p = 0.121) and trial (p = 0.777) for average saccade’s velocity. The mean ± SD of the difference of the total fixations before and after intervention across both trials was 1.04 ± 3.63 and there was an observable difference in the trial number (p = 0.025). The mean ± SD of the differences for the Inter-Saccadic Interval and the fixation polyarea before and after intervention across both trials were 1.86 ± 22.99 msec and 0.51 ± 59.11 mm2 and no observable differences for the intervention, gender and trial. Conclusion The results provide evidence on the reliability of the K-D ET, and the eye-tracking components and demonstrate the relationship between completion time and other variables of the K-D ET system. This is vital as the use of the K-DT may be increasing and the combination of the K-DT and eye tracking as one single package highlights the need to specifically measure the reliability of this combined unit.

Abstract
An LTR-based quantitative PCR (qPCR) assay was modified and optimized for the quantification of total HIV-1 nucleic acids in plasma and PBMC. TaqMan qPCR primers and probes were designed against the NCBI/LANL HIV-1 compendium database by analyzing sequences used in assays for sensitive cross-clade detection of HIV-1 as reported in the literature and elucidating regions of improved cross-subtype specificity. Inosine and mixed nucleotide bases were included at polymorphic sites. Real-time RT-qPCR and qPCR were performed on plasma viral RNA and cellular lysates. A step-up amplification approach to allow binding of primers across polymorphic regions showed improved sensitivity compared to universal cycling. Unlike a lead competing laboratory-developed assay, all major HIV-1 subtypes, and a wide range of recombinants from a 127-member diversity panel were detected and accurately quantified in spiked plasmas. Semi-nested PCR increased detection sensitivity even further. The assay was able to detect down to 88 copies/mL of HIV-1 in plasma with 95% efficiency or the equivalent of a single infected cell. The PCR assay will be valuable in studies that monitor very low viral levels including residual or break through HIV-1 in patients receiving antiretroviral therapy, in HIV-1 cure, and in other research studies.

Abstract
We report the synthesis of seven-membered iminosugars derived from a 3S-acetamido-4R,5R,6S-trihydroxyazepane scaffold and their evaluation as inhibitors of functionally related exo-N-acetylhexosaminidases including human O-GlcNAcase (OGA), human lysosomal β-hexosaminidase (HexAB), and Escherichia coli NagZ. Capitalizing on the flexibility of azepanes and the active site tolerances of hexosaminidases, we explore the effects of epimerization of stereocenters at C-3, C-5 and C-6 and C-alkylation at the C-2 or C-7 positions. Accordingly, epimerization at C-6 (L-ido) and at C-5 (D-galacto) led to selective HexAB inhibitors whereas introduction of a propyl group at C-7 on the C-3 epimer furnished a potent NagZ inhibitor.

Abstract
The hazards associated with radium-containing materials were largely unknown when they were first introduced into household and other products over a century ago. Radium was also originally thought to have beneficial health properties, leading to confusion amongst the public about the safety of radium in household products and food items. When the adverse health effects associated with radium were discovered and became well known, radium products became unpopular and were prohibited in some countries. In the United States, after the hazards associated with radium became known, radium was first regulated by individual states in the late 1920s and early 1930s. Later, the US Nuclear Regulatory Commission (NRC) was given a role in the regulation of discrete sources of radium with the passage of the Energy Policy Act of 2005. After passage of the Act, the NRC began to systematically identify sites around the country where radium was used and reached out to site owners to determine whether existing radium contamination could pose a risk to public health and safety and the environment. The NRC devised a graded approach in response to its new regulatory responsibilities to address potential public health and safety issues at legacy radium sites. By September 2019, the NRC had dispositioned all the sites that were identified as having potential contamination from historical radium within its regulatory purview in non-Agreement States. The staff worked with site owners and federal, state and local officials, as needed, to properly disposition the sites to ensure that each site either meets the applicable criteria for unrestricted use or has controls in place to limit access during remediation so that no site poses an unacceptable risk to public health and safety and the environment.

Abstract
Background Intravenous drug use (IVDU) is a risk factor for development of S. aureus bacteremia (SAB) and prevalent in opiate use disorder (OUD). While the standard of care involves treating the underlying OUD with medically assisted therapy (MAT), it is unknown how much impact this has on clinical endpoints. Methods We conducted a retrospective cohort study of patients with IVDU with hospitalizations for SAB during a 28-month period from 9/2016 through 12/2018 in 10 urban and rural North Carolina hospitals in a single large health system. We compared outcomes for patients receiving prescription for MAT at discharge versus no MAT at discharge. MAT was defined as receiving methadone, buprenorphine, or naltrexone. Patients who expired inpatient were excluded from analysis. Clinical endpoints were 30- and 90-day mortality and 30-day SAB-related readmissions. Results Of the 174 patients, 28% received a prescription for MAT at discharge. The majority of the patients were Caucasian (88%), female (57%), with mean age of 37 years. Factors that significantly increased likelihood of MAT at discharge were female gender (34% vs 20%, p=0.04), having a complicated SAB (33% vs 28%, p=0.01), presence of a spinal/epidural abscess (57% vs 43%, p=0.002), and increased length of stay (LOS) (37 days vs 24 days, p=< 0.001). No difference in 30- and 90-day mortality was observed; only one patient in each group died within 90 days. Prescription for any MAT at discharge was associated with a significant decrease in the risk of SAB-related 30-day readmission (0% vs 17%, p=0.002). Table 1: Baseline Characteristics ![]()
Table 2: MAT & Clinical Outcomes in S. aureus Bacteremia ![]()
Figure 1: Medically Assisted Therapy Prescribed at Discharge Conclusion Gender, more complicated infections, and prolonged LOS may increase the likelihood of receiving a prescription for MAT at discharge. MAT prescription at discharge may decrease the risk of 30-day SAB related readmission (NNT 5.9). The results suggest that provision of MAT to patients with SAB and history of IVDU should be incorporated into standardized treatment guidelines. ![]()

Abstract
OBJECTIVES To describe the training injury incidence in amateur women's rugby union in New Zealand over two consecutive seasons. DESIGN A prospective cohort observational study METHODS: A total of 69 amateur women's rugby 15s team playerswere observed. Training exposure and training injury incidence were calculated. RESULTS The 38 training injuries resulted in a total injury incidence of 11.4 (8.3-15.6) per 1,000 training-hours. There were 12 injuries that resulted in a time-loss injury incidence of 3.6 (95% CI: 2.0-6.3) per 1,000 training-hours. Forwards recorded more total (RR: 1.8 [95% CI: 0.9-3.5]; p=0.0516) and time-loss (RR: 2.0 [95% CI: 0.6-6.6]; p=0.2482) injuries than Backs. The tackle was the most common injury cause for total (3.0 [95% CI: 1.6-5.6] per 1,000 training-hours.) injuries, but collisions (1.5 [95% CI: 0.6-3.6] per 1,000 training-hours.) with the ground or another person were the most common cause for time-loss injuries.The training injuries occurred most often to the lower limb and during the latter part of training sessions. These injuries were mostly minor in nature resulting in minimal time-loss away from training. DISCUSSION The time-loss injury incidence (3.6 per 1,000 training-hours.) for the amateur women's rugby 15s team players was higher than that reported for National (1.2 per 1,000 training-hours.) and Rugby World Cup for women (0.2 to 3.0 per 1,000 training-hours.) competitions. CONCLUSION The training injury incidence in amateur women's rugby union in New Zealand was higher than that reported for national and international rugby union injury incidences.

Abstract
OBJECTIVE To investigate the use of the King-Devick (K-D) test for sideline assessment of concussive injuries in a New Zealand amateur women's rugby union team. DESIGN Prospective cohort observational. METHODS All players were K-D tested during pre-season using a tablet (iPad; Apple Inc., Cupertino, CA). Differences in K-D scores and test-retest reliability were calculated for baseline test scores, baseline, and post-injury (concussion) sideline assessment and baseline and post-season testing scores for tests by year and as a combined score. RESULTS One training-related (0.3 per 1000 training-hrs) and nine match-related (16.1 per 1000 match-hrs) concussions were recorded. The K-D post-injury (concussion) sideline test score were significantly slower than established baseline (-4.4 [-5.8 to -3.4] s; χ2(1) = 42.2; p < 0.0001; t(9) = -4.0; p = 0.0029; d = -0.8). There was good-to-excellent reliability of the K-D test for baseline (ICC: 0.84 to 0.89), post-injury (concussion) sideline assessment (ICC: 0.82 to 0.97) and post-season evaluation (ICC: 0.79 to 0.83). DISCUSSION By utilising the baseline to post-injury (concussion) assessment comparisons, any player with a post-injury (concussion) assessment slowing of their K-D test time, regardless of whether the player has, or has not had a witnessed insult, should be withheld from any further participation until they are evaluated by a medical professional trained in the management of concussion. CONCLUSION This study has provided additional evidence to support the use of the K-D test as a frontline method of assessing concussion with good to excellent reliability of the test for baseline, side-line assessment and post-season evaluation.

Abstract
We report the first measurement of the (e,e^{'}p) three-body breakup reaction cross sections in helium-3 (^{3}He) and tritium (^{3}H) at large momentum transfer [⟨Q^{2}⟩≈1.9 (GeV/c)^{2}] and x_{B}>1 kinematics, where the cross section should be sensitive to quasielastic (QE) scattering from single nucleons. The data cover missing momenta 40≤p_{miss}≤500 MeV/c that, in the QE limit with no rescattering, equals the initial momentum of the probed nucleon. The measured cross sections are compared with state-of-the-art ab initio calculations. Overall good agreement, within ±20%, is observed between data and calculations for the full p_{miss} range for ^{3}H and for 100≤p_{miss}≤350 MeV/c for ^{3}He. Including the effects of rescattering of the outgoing nucleon improves agreement with the data at p_{miss}>250 MeV/c and suggests contributions from charge-exchange (SCX) rescattering. The isoscalar sum of ^{3}He plus ^{3}H, which is largely insensitive to SCX, is described by calculations to within the accuracy of the data over the entire p_{miss} range. This validates current models of the ground state of the three-nucleon system up to very high initial nucleon momenta of 500 MeV/c.

Abstract
Abstract
Foot-and-mouth disease (FMD) is a highly contagious disease of livestock affecting animal production and trade throughout Asia and Africa. Understanding FMD virus (FMDV) global movements and evolution can help to reconstruct the disease spread between endemic regions and predict the risks of incursion into FMD-free countries. Global expansion of a single FMDV lineage is rare but can result in severe economic consequences. Using extensive sequence data, we have reconstructed the global space-time transmission history of the O/ME-SA/Ind-2001 lineage (which normally circulates in the Indian sub-continent) providing evidence of at least fifteen independent escapes during 2013–7 that have led to outbreaks in North Africa, the Middle East, Southeast Asia, and the Far East and the FMD-free islands of Mauritius. We demonstrated that sequence heterogeneity of this emerging FMDV lineage is accommodated within two co-evolving divergent sublineages, and that recombination by exchange of capsid-coding sequences can impact upon the reconstructed evolutionary histories. Thus, we recommend that only sequences encoding the outer capsid proteins should be used for broad-scale phylogeographical reconstruction. These data emphasize the importance of the Indian subcontinent as a source of FMDV that can spread across large distances and illustrates the impact of FMDV genome recombination on FMDV molecular epidemiology.

Abstract
Aim Premise plumbing may disseminate the bacteria Legionella pneumophila and Mycobacterium avium, the causative agents for legionellosis and pulmonary nontuberculous mycobacterium disease respectively. Methods and Results Using quantitative PCR, the occurrence and persistence of L. pneumophila, L. pneumophila serogroup (Sg)1 and M. avium were evaluated in drinking water samples from 108 cold water taps (residences: n = 43) and (office buildings: n = 65). Mycobacterium avium, L. pneumophila and L. pneumophila Sg1 were detected 45, 41 and 25% of all structures respectively. Two occurrence patterns were evaluated: sporadic (a single detection from the three samplings) and persistent (detections in two or more of the three samples). Conclusions The micro‐organism's occurrence was largely sporadic. Office buildings were prone to microbial persistence independent of building age and square footage. Microbial persistence at residences was observed in those older than 40 years for L. pneumophila and was rarely observed for M. avium. The microbial occurrence was evenly distributed between structure types but there were differences in density and persistence. Significance of and Impact of the Study The study is important because residences are often suspected to be the source when a case of disease is reported. These data demonstrate that this may not be the case for a sporadic incidence.

Abstract
We have adapted the methodology of Berry et al. (2012) for Intensity Modulated Radiotherapy (IMRT) and Volumetric Modulated Arc Therapy (VMAT) treatments at a fixed source to imager distance (SID) based on the manufacturer's through-air portal dose image prediction algorithm. In order to fix the SID a correction factor was introduced to account for the change in air gap between patient and imager. Commissioning data, collected with multiple field sizes, solid water thicknesses and air gaps, were acquired at 150 cm SID on the Varian aS1200 EPID. The method was verified using six IMRT and seven VMAT plans on up to three different phantoms. The method's sensitivity and accuracy were investigated by introducing errors. A global 3%/3 mm gamma was used to assess the differences between the predicted and measured portal dose images. The effect of a varying air gap on EPID signal was found to be significant - varying by up to 30% with field size, phantom thickness, and air gap. All IMRT plans passed the 3%/3 mm gamma criteria by more than 95% on the three phantoms. 23 of 24 arcs from the VMAT plans passed the 3%/3 mm gamma criteria by more than 95%. This method was found to be sensitive to a range of potential errors. The presented approach provides fast and accurate in-vivo EPID dosimetry for IMRT and VMAT treatments and can potentially replace many pre-treatment verifications.

Abstract
Cylindrospermopsin (CYN) is a toxin associated with numerous species of freshwater cyanobacteria throughout the world. It is postulated to have caused an episode of serious illnesses in Australia through treated drinking water, as well as lethal effects in livestock exposed to water from farm ponds. Toxicity included effects indicative of both hepatic and renal dysfunction. In humans, symptoms progressed from initial hepatomegaly, vomiting, and malaise to acidosis and hypokalemia, bloody diarrhea, and hyperemia in mucous membranes. Laboratory animal studies predominantly involved the intraperitoneal (i.p.) route of administration and confirmed this pattern of toxicity with changes in liver enzyme activities and histopathology consistent with hepatic injury and adverse renal effects. The aim of this study was designed to assess subchronic oral exposure (90 d) of purified CYN from 75 to 300 µg/kg/d in mouse. At the end of the dosing period, examinations of animals noted (1) elevated organ to body weight ratios of liver and kidney at all dose levels, (2) treatment-related increases in serum alanine aminotransferase (ALT) activity, (3) decreased blood urea nitrogen (BUN) and cholesterol concentrations in males, and (4) elevated monocyte counts in both genders. Histopathological alterations included hepatocellular hypertrophy and cord disruption in the liver, as well as renal cellular hypertrophy, tubule dilation, and cortical tubule lesions that were more prominent in males. A series of genes were differentially expressed including Bax (apoptosis), Rpl6 (tissue regeneration), Fabp4 (fatty acid metabolism), and Proc (blood coagulation). Males were more sensitive to many renal end points suggestive of toxicity. At the end of exposure, toxicity was noted at all dose levels, and the 75 µg/kg group exhibited significant effects in liver and kidney/body weight ratios, reduced BUN, increased serum monocytes, and multiple signs of histopathology indicating that a no-observed-adverse-effect level could not be determined for any dose level.

Abstract
Elderly people have a greater need for domestic heating given the time they spend at home and the decline in the body thermoregulation that occurs with ageing. The use of domestic heating by 200 mentally competent newly admitted elderly in patients was evaluated by means of a questionnaire survey. Most patients (69%) were aware of the addition of value added tax (VAT) to their fuel bill and 31 % said they had reduced the amount of heating they use because of this. A third of patients (29.5%) said they had difficulty keeping warm prior to this admission. The majority of patients said they could not manage to keep warm in the winter without financial hardship. In addition, 29% said they had reduced the amount spent on food in order to pay for fuel bills. This study suggests that cold may contribute to hospital admissions in elderly patients. This should have implications for government spending and taxation policy on domestic heating.

Abstract
BACKGROUND Research supports robust associations between childhood bullying victimization and mental health problems in childhood/adolescence and emerging evidence shows that the impact can persist into adulthood. We examined the impact of bullying victimization on mental health service use from childhood to midlife. METHOD We performed secondary analysis using the National Child Development Study, the 1958 British Birth Cohort Study. We conducted analyses on 9242 participants with complete data on childhood bullying victimization and service use at midlife. We used multivariable logistic regression models to examine associations between childhood bullying victimization and mental health service use at the ages of 16, 23, 33, 42 and 50 years. We estimated incidence and persistence of mental health service use over time to the age of 50 years. RESULTS Compared with participants who were not bullied in childhood, those who were frequently bullied were more likely to use mental health services in childhood and adolescence [odds ratio (OR) 2.53, 95% confidence interval (CI) 1.88-3.40] and also in midlife (OR 1.30, 95% CI 1.10-1.55). Disparity in service use associated with childhood bullying victimization was accounted for by both incident service use through to age 33 years by a subgroup of participants, and by persistent use up to midlife. CONCLUSIONS Childhood bullying victimization adds to the pressure on an already stretched health care system. Policy and practice efforts providing support for victims of bullying could help contain public sector costs. Given constrained budgets and the long-term mental health impact on victims of bullying, early prevention strategies could be effective at limiting both individual distress and later costs.

Abstract
BACKGROUND Head impacts and resulting head accelerations cause concussive injuries. There is no standard for reporting head impact data in sports to enable comparison between studies. OBJECTIVE The aim was to outline methods for reporting head impact acceleration data in sport and the effect of the acceleration thresholds on the number of impacts reported. METHODS A systematic review of accelerometer systems utilised to report head impact data in sport was conducted. The effect of using different thresholds on a set of impact data from 38 amateur senior rugby players in New Zealand over a competition season was calculated. RESULTS Of the 52 studies identified, 42% reported impacts using a >10-g threshold, where g is the acceleration of gravity. Studies reported descriptive statistics as mean ± standard deviation, median, 25th to 75th interquartile range, and 95th percentile. Application of the varied impact thresholds to the New Zealand data set resulted in 20,687 impacts of >10 g, 11,459 (45% less) impacts of >15 g, and 4024 (81% less) impacts of >30 g. DISCUSSION Linear and angular raw data were most frequently reported. Metrics combining raw data may be more useful; however, validity of the metrics has not been adequately addressed for sport. Differing data collection methods and descriptive statistics for reporting head impacts in sports limit inter-study comparisons. Consensus on data analysis methods for sports impact assessment is needed, including thresholds. Based on the available data, the 10-g threshold is the most commonly reported impact threshold and should be reported as the median with 25th and 75th interquartile ranges as the data are non-normally distributed. Validation studies are required to determine the best threshold and metrics for impact acceleration data collection in sport. CONCLUSION Until in-field validation studies are completed, it is recommended that head impact data should be reported as median and interquartile ranges using the 10-g impact threshold.

Abstract
ver the past two decades, healthcare-associated infections (HCAI) have emerged as a significant threat to high quality health care. The technological advances made in the treatment of many diseases and disorders are being undermined by the transmission of infections within healthcare settings, especially the emergence of antimicrobial resistant strains of Staphylococcus aureus and enterococci that are now endemic in some healthcare environments. The financial and personal costs of HCAI in terms of the economic consequences to the National Health Service (NHS) and the physical, social and psychological costs to patients and their relatives have increased both government and public awareness of the risks associated with healthcare interventions and in particular the consequences of HCAI. The risk of acquiring HCAI continues to attract intense media interest. Reports of dirty hospitals and stories of healthcare workers failing to observe even the most rudimentary hygiene and other infection prevention and control measures are causing profound anxiety among service users. The public is fast losing confidence in the NHS to safely care for them and this dissatisfaction has propelled HCAI to the top of an increasingly urgent political healthcare agenda. The Department of Health (DH) has focused a number of initiatives on combating HCAI, including the development of national evidence-based infection prevention and control guidelines for acute and primary care settings (Pratt et al, 2001; Pellowe et al, 2003), a research programme to identify a range of effective strategies for combating antimicrobial resistance and more recently setting out a strategy for reducing HCAI and improving environmental hygiene in healthcare settings (DH, 2002; DH, 2004). DH strategy emphasises the importance of ensuring that infection prevention and control training is included in the induction programme for all NHS staff, both clinical and nonclinical, including agency and locum staff, and that this training becomes part of their continuing personal development plans. Professor Christine Beasley, the chief nursing officer at the DH has since taken responsibility for actualising many aspects of this strategy, especially ensuring that the required training is made available for all 1.3 million NHS staff by the end of 2005. Providing that training became the responsibility of the NHS University (NHSU), which commissioned the Richard Wells Research Centre at Thames Valley University London (TVU) along with their Dublin-based educational development partner, Intuition Publishing Ltd, to develop an appropriate and accessible state-of-the-art blended e-learning training programme. In this article, we describe how we designed and structured the programme so that it can be used as an essential tool in orientation/induction, staff development and in-service education programmes for all NHS staff.

Abstract
Objective: To develop and evaluate a qualitative and quantitative instrument for selecting the ideal mobility aid for those with mobility disorders. Setting: A district general hospital-based geriatric unit. Subjects: Elderly inpatients and outpatients with mobility disorders. Interventions: Structured assessments with different mobility aids to select the most suitable. Outcome measures: Safety, stance, stability, step/stride pattern and speed were considered. Results: The 'S' test successfully selected an aid for all 49 subjects. For most this aid offered marked improvement in qualitative and quantitative aspects of gait when compared with the subject's usual aid. Conclusions: The 'S' test is an effective tool for selecting mobility aids within an institutional setting.

Abstract
AIM To determine whether the King-Devick (K-D) test used as a sideline test in junior rugby league players over 12 matches in a domestic competition season could identify witnessed and incidentally identified episodes of concussion. METHODS A prospective observational cohort study of a club level junior rugby league team (n=19) during the 2014 New Zealand competition season involved every player completing two pre-competition season baseline trials of the K-D test. Players removed from match participation, or who reported any signs or symptoms of concussion were assessed on the sideline with the K-D test and referred for further medical assessment. Players with a pre- to post-match K-D test difference >3s were referred for physician evaluation. RESULTS The baseline test-retest reliability of the K-D test was high (rs=0.86; p<0.0001). Seven concussions were medically identified in six players who recorded pre- to post-match K-D test times greater than 3s (mean change of 7.4s). Post-season testing of players demonstrated improvement of K-D time scores consistent with learning effects of using the K-D test (67.7s vs. 62.2s). DISCUSSION Although no witnessed concussions occurred during rugby play, six players recorded pre- to post-match changes with a mean delay of 4s resulting in seven concussions being subsequently confirmed post-match by health practitioners. All players were medically managed for a return to sports participation. CONCLUSION The K-D test was quickly and easily administered making it a practical sideline tool as part of the continuum of concussion assessment tools for junior rugby league players.

Abstract
In 2012, a plan to develop Stereotactic treatments using a Cyberknife was unveiled at the Hermitage Medical Clinic, Dublin. Due to planning restrictions the new facility had to be contained in the existing hospital's blue print with the only available location being an unused CT simulation room. The room design would be different from conventional radiotherapy bunkers due to the fact the Cyberknife can fire an unfiltered beam in any direction bar the roof (restriction of 22° above the horizontal). Therefore all walls must be primary barriers with the roof designed to protect against the large leakage radiation resulting from the high MU's used during the treatments. Space consideration indicated that concrete alone could not be used to restrict the radiation beam to acceptable limits. To this end a combination of steel, lead, normal and heavy concrete were used to meet the dose constraints established by the Irish licensing authorities.

Abstract
The histone methyltransferase Enhancer of Zeste Homolog 2 (EZH2) is frequently dysregulated in cancers, and gain-of-function (GOF) EZH2 mutations have been identified in non-Hodgkin lymphomas. Small-molecule inhibitors against EZH2 demonstrated anti-tumor activity in EZH2-mutated lymphomas and entered clinical trials. Here, we developed models of acquired resistance to EZH2 inhibitor EI1 with EZH2-mutated lymphoma cells. Resistance was generated by secondary mutations in both wild-type (WT) and GOF Y641N EZH2 alleles. These EZH2 mutants retained the substrate specificity of their predecessor complexes but became refractory to biochemical inhibition by EZH2 inhibitors. Resistant cells were able to maintain a high level of H3K27Me3 in the presence of inhibitors. Interestingly, mutation of EZH2 WT alone generated an intermediate resistance phenotype, which is consistent with a previously proposed model of cooperation between EZH2 WT and Y641N mutants to promote tumorigenesis. In addition, the findings presented here have implications for the clinical translation of EZH2 inhibitors and underscore the need to develop novel EZH2 inhibitors to target potential resistance emerging in clinical settings.
