Abstract
INTRODUCTION Measuring cortisol during military training offers insights into physiological responses to stress. We attempted precisely timed, cortisol awakening response (CAR) and pre-sleep cortisol (PSC), and diurnal slope (peak morning minus evening cortisol), during a British Army exercise. We aimed to understand cortisol dynamics and evaluate the feasibility of CAR and PSC in this environment. METHOD Setting: high-intensity, 10-day infantry exercise. Participants: regular infantry soldiers exercising (EX, n=25) or headquarters-based (HQ, n=6). Participants undertook PSC and WAKE and WAKE+30 min samples after 1-2 days, 5-6 days and 9-10 days. Wrist-worn GENEActiv accelerometers were used to assess sleep duration in EX only. Samples taken ±15 min from prespecified time points were deemed adherent. Validated questionnaires were used to measure resilience and perceived stress. Cortisol and cortisone were measured simultaneously by liquid chromatography tandem mass spectrometry. RESULTS From adherent participants' samples, CAR was positive and tended to decrease as the exercise progressed. From all available data, HQ demonstrated greater diurnal slope than EX (F=7.68, p=0.02), reflecting higher morning cortisol (F=4.72, p=0.038) and lower PSC (p=0.04). No differences were seen in cortisol:cortisone ratio. 26.1% of CAR samples were adherent, with moderately strong associations between adherence and stress (r=0.41, p=0.009) but no association between adherence and day of exercise (χ2=0.27, p=0.8), sleep duration (r=-0.112, p=0.43) or resilience (r=-0.79, p=0.75). Test-retest reliability ratings for CAR were Cronbach's α of 0.48, -11.7 and 0.34 for the beginning, middle and end of the exercise, respectively. CONCLUSIONS We observed a reduction in morning cortisol and decreased diurnal slope during a high-intensity military exercise, compared with the HQ comparator cohort in whom diurnal slope was preserved. A carefully timed CAR was not feasible in this setting.

Abstract
INTRODUCTION Wearable sensor technologies enable Defence to optimise human performance, remotely identify physiological abnormalities and enhance medical support. Maximising the acceptability of devices will ensure they are worn alongside other equipment. This study assessed the acceptability and comfort of four devices at different anatomical locations during military training. METHOD A cross-sectional pilot study during a live firing infantry exercise or adventurous training assessed four anatomical locations concurrently over 5 days: finger, wrist, upper arm and chest. Participants rated comfort, acceptability and preference using a standardised questionnaire after 12 hours and 5 days of wear. RESULTS Twenty-one regular British Army personnel soldiers participated, aged 24.4 (4.3) years. The upper arm location received the highest rating by participants for comfort, followed in order by wrist, finger and chest (p=0.002, Χ2=40.0). The finger was most commonly identified as uncomfortable during specific activities (76%), followed by chest (48%), wrist (23%) and upper arm devices (14%). There was no significant difference in participant confidence in the devices to collect data or allow movement, but there was a trend towards greater confidence in upper arm and wrist locations to stay in position than the others (p=0.059, Χ2=28.0). After 5 days of wear, 43% of participants said they preferred the upper arm for comfort, followed by wrist (36%), finger (24%) and chest (10%). 73% and 71% would wear the wrist and upper arm devices on deployed operations, compared with 29% and 24% for chest and finger devices, respectively. CONCLUSION The upper arm location offered greater acceptability and comfort than finger, wrist or chest locations. It is essential to consider such findings from occupationally relevant settings when selecting wearable technology. A larger service evaluation in diverse settings is recommended to guide the choice of the most acceptable wearable devices across different equipment, roles and environments.

Abstract
Dravet syndrome (DS) is a severe genetic epilepsy primarily caused by de novo mutations in a voltage-activated sodium channel gene (SCN1A). Patients face life-threatening seizures that are largely resistant to available anti-seizure medications (ASM). Preclinical DS animal models are a valuable tool to identify candidate ASMs for these patients. Among these, scn1lab mutant zebrafish exhibiting spontaneous seizure-like activity are particularly amenable to large-scale drug screening. Prior screening in a scn1lab mutant zebrafish line generated using N-ethyl-N-nitrosourea (ENU) identified valproate, stiripentol, and fenfluramine e.g., Federal Drug Administration (FDA) approved drugs with clinical application in the DS population. Successful phenotypic screening in scn1lab mutant zebrafish consists of two stages: (i) a locomotion-based assay measuring high-velocity convulsive swim behavior and (ii) an electrophysiology-based assay, using in vivo local field potential (LFP) recordings, to quantify electrographic seizure-like events. Using this strategy more than 3000 drug candidates have been screened in scn1lab zebrafish mutants. Here, we curated a list of nine additional anti-seizure drug candidates recently identified in preclinical models: 1-EBIO, AA43279, chlorzoxazone, donepezil, lisuride, mifepristone, pargyline, soticlestat and vorinostat. First-stage locomotion-based assays in scn1lab mutant zebrafish identified only 1-EBIO, chlorzoxazone and lisuride. However, second-stage LFP recording assays did not show significant suppression of spontaneous electrographic seizure activity for any of the nine anti-seizure drug candidates. Surprisingly, soticlestat induced frank electrographic seizure-like discharges in wild-type control zebrafish. Taken together, our results failed to replicate clear anti-seizure efficacy for these drug candidates highlighting a necessity for strict scientific standards in preclinical identification of ASMs.

Abstract
Background Older people receive care from multiple providers which often results in a lack of coordination. The Information and Communication Technology (ICT) enabled value-based methodology for integrated care (ValueCare) project aims to develop and implement efficient outcome-based, integrated health and social care for older people with multimorbidity, and/or frailty, and/or mild to moderate cognitive impairment in seven sites (Athens, Greece; Coimbra, Portugal; Cork/Kerry, Ireland; Rijeka, Croatia; Rotterdam, the Netherlands; Treviso, Italy; and Valencia, Spain). We will evaluate the implementation and the outcomes of the ValueCare approach. This paper presents the study protocol of the ValueCare project; a protocol for a pre-post controlled study in seven large-scale sites in Europe over the period between 2021 and 2023. Methods A pre-post controlled study design including three time points (baseline, post-intervention after 12 months, and follow-up after 18 months) and two groups (intervention and control group) will be utilised. In each site, (net) 240 older people (120 in the intervention group and 120 in the control group), 50–70 informal caregivers (e.g. relatives, friends), and 30–40 health and social care practitioners will be invited to participate and provide informed consent. Self-reported outcomes will be measured in multiple domains; for older people: health, wellbeing, quality of life, lifestyle behaviour, and health and social care use; for informal caregivers and health and social care practitioners: wellbeing, perceived burden and (job) satisfaction. In addition, implementation outcomes will be measured in terms of acceptability, appropriateness, feasibility, fidelity, and costs. To evaluate differences in outcomes between the intervention and control group (multilevel) logistic and linear regression analyses will be used. Qualitative analysis will be performed on the focus group data. Discussion This study will provide new insights into the feasibility and effectiveness of a value-based methodology for integrated care supported by ICT for older people, their informal caregivers, and health and social care practitioners in seven different European settings. Trial registration ISRCTN registry number is 25089186. Date of trial registration is 16/11/2021.

Abstract
Disease modification has become a well-established concept in several therapeutic areas; however, no widely accepted definition of disease modification exists for SLE. We reviewed established definitions of disease modification in other conditions and identified a meaningful effect on ‘disease manifestations’ (ie, signs, symptoms and patient-reported outcomes) and on ‘disease outcomes’ (eg, long-term remission or progression of damage) as the key principles of disease modification, indicating a positive effect on the natural course of the disease. Based on these findings and the treatment goals and outcome measures for SLE, including lupus nephritis, we suggest a definition of disease modification based on disease activity indices and organ damage outcomes, with the latter as a key anchor. A set of evaluation criteria is also suggested. Establishing a definition of disease modification in SLE will clarify which treatments can be considered disease modifying, provide an opportunity to harmonise future clinical trial outcomes and enable comparison between therapies, all of which could ultimately help to improve patient outcomes. This publication seeks to catalyse further discussion and provide a framework to develop an accepted definition of disease modification in SLE.

Abstract
Abstract
Introduction
Fontan-associated Liver Disease (FALD) is an extracardiac complication with a substantial disease burden that can reduce quality of life, increase healthcare demand and result in premature mortality. Effective FALD screening is paramount in preventing late-stage complications.
Purpose
To assess the adherence of a tertiary adult congenital heart disease referral centre to FALD screening.
Methods
1. A total of 256 Fontan patients reviewed at our centre between 1st January 1977 and 31st December 2020 were identified from the congenital cardiac surgical database and the adult congenital heart disease clinical nurse specialist database.
2. The following patients were excluded: aged under 18 years on 31st December 2020 (103 cases), out of region or loss to follow-up (35 cases), death (30 cases), cardiac or liver transplantation (4 cases) and Fontan takedown (3 cases.) The mean endpoint (death, transplant or Fontan takedown) was 30 years.
3. The final study population included 81 patients.
4. Data was collected by review of clinic letters, blood test and imaging results from electronic records between 1st January 2018 and 31st December 2020.
5. The data were analysed to determine whether the screening recommendations from “Fontan-Associated Liver Disease: Proceedings from the American College of Cardiology Stakeholders Meeting, October 1 to 2, 2015, Washington DC” (ACC Stakeholders Meeting) were performed.
Results
The ACC Stakeholders Meeting recommended history taking and physical examination at least once a year with Fontan blood tests (full blood count, urea and electrolytes, liver function tests, alpha-fetoprotein and international normalized ratio) and imaging (abdominal ultrasound, computerised tomography or magnetic resonance imaging) at least once every three years.
Of the 81 patients (47 male, mean age 27±8.3 years), the mean age of Fontan completion was 6.6±5.3 years. The mean follow-up period since Fontan completion was 20±8.1 years. History taking and physical examination were documented in 84% (68/81) and 79% (64/81) of patients respectively. 60% (59/81) had a full set of Fontan blood tests taken which increased to 73% (49/81) if alpha-fetoprotein was excluded while imaging was performed in 80% (65/81) of cases.
Overall, 46% (37/81) cases had abnormal Fontan blood test or imaging. Hepatology referral was made in only 21% (17/81) of cases and MELD-XI score was not documented.
Conclusions
FALD screening tests were frequently underperformed compared to international guidance. Adherence may be improved by 1) promoting a Fontan blood test bundle; 2) implementing a standardised letter template which includes an investigation date list; 3) advocating MELD-XI score; and 4) exploring a joint cardiac and hepatology Fontan clinic.

Abstract
Abstract
Introduction
The COVID pandemic resulted in a shutdown of facilities and resources globally. With drastic changes in the provision of services available in the health sector, so too were medical students’ provision of learning. With the onslaught of COVID and the need for ongoing learning resources for students, novel methods to maintain adequate surgical patient exposure and student interaction on a platform amenable to the interactive format required was devised using a virtual platform to compliment current pedagogical approaches.
Method
This was a randomised control trial to evaluate the perceived use of remote learning in place of surgical bedside teaching in the COVID-19 era. Medical students in a regional hospital were recruited and randomised to undergo the bedside teaching in person or receive the teaching virtually through a Xpert eye, smart glasses to facilitate connections remotely. Feedback questionnaires and exit interviews carried out following each session. Content analysis of transcripts was performed to evaluate the presence and quality of perceived learning, benefits, and limitations.
Results
Feedback demonstrated greater engagement, satisfaction, involvement, and learning (p < 0.01) in the bedside teaching group. Content analysis yielded three main themes: Interpersonal content, technological features, and provision of content. Students reported the virtual teaching was an acceptable alternative in the current climate of social distancing and reduced patient access.
Conclusions
The current pandemic poses a risk to adequate patient exposure to patient centred learning. Teaching sessions received remotely are an acceptable alternative in the current climate of reduced clinical access, however bedside teaching remains the preferred method of learning.

Abstract
BACKGROUND: Cross-border migrants at the Thailand-Myanmar border are an underserved and vulnerable population. We aimed to identify the causes and risk factors for TB mortality at a migrant-friendly TB programme.METHODS: Routinely collected data on TB cases, treatment outcomes and causes of death were analysed for adult TB cases diagnosed between January 2013 and April 2017. Mortality in the 6 months post-diagnosis was calculated and risk factors were identified using multivariable Poisson regression.RESULTS: Of the 1344 TB cases diagnosed, 1005 started treatment and 128 died. Case fatality rate was 9.5% and the TB mortality rate was 2.4/100 person-months. The number of pre-treatment deaths (33/128) and losses to follow-up (9.0%) were high. Among cases enrolled in treatment, the treatment success rate was 79.8%. When stratified by HIV status, case fatality was higher in HIV-positive cases not on antiretroviral therapy (ART) (90.3%) or with unknown HIV status (31.8%) than those on ART (14.3%) or HIV-negative (8.6%).CONCLUSION: This TB programme achieved high treatment success rates in a population with a substantial burden of TB-HIV coinfection. Expanding access to HIV testing and ART is crucial to reduce mortality. Striving towards same-day TB diagnosis and treatment could reduce death and loss to follow-up.

Abstract
Introduction The COVID pandemic resulted in a shutdown of facilities and resources globally. With drastic changes in the provision of services available in the health sector, so too were medical students’ provision of learning. With the onslaught of COVID and the need for ongoing learning resources for students, novel methods to maintain adequate surgical patient exposure and student interaction on a platform amenable to the interactive format required was devised using a virtual platform to compliment current pedagogical approaches. Methods This was a randomised control trial to evaluate the perceived use of remote learning in place of surgical bedside teaching in the COVID-19 era. Medical students in a regional hospital were recruited and randomised to undergo the bedside teaching in person or receive the teaching virtually through a Xpert eye, smart glasses to facilitate connections remotely. Feedback questionnaires and exit interviews carried out following each session. Content analysis of transcripts was performed to evaluate the presence and quality of perceived learning, benefits and limitations. Results Feedback demonstrated greater engagement, satisfaction, involvement and learning (p < 0.01) in the bedside teaching group. Content analysis yielded three main themes; Interpersonal content, technological features, and provision of content. Students reported the virtual teaching was an acceptable alternative in the current climate of social distancing and reduced patient access. Conclusion The current pandemic poses a risk to adequate patient exposure to patient centred learning. Teaching sessions received remotely are an acceptable alternative in the current climate of reduced clinical access, however bedside teaching remains the preferred method of learning.

Abstract
Oral infection with human papillomavirus (HPV) is likely to underpin the rapidly rising incidence of oropharyngeal squamous cell carcinoma; however, there are few data describing the natural history of oral HPV infection. We recruited 704 participants aged 20 to 70 years from worksites, universities and primary care practices in Brisbane, Australia. Participants completed questionnaires at baseline, 12 and 24 months and donate four saliva samples at baseline, 6, 12 and 24 months for HPV polymerase chain reaction testing and typing. We estimated the prevalence of oral HPV infection at baseline, incidence of new infections among those HPV-negative at baseline, clearance rate and persistent infections. At baseline, 10.7% of participants had oral HPV infections from 26 different HPV types. Sexual behaviours were associated with oral HPV infection, including more partners for passionate kissing (29 or more; odds ratio [OR] 3.4, 95% confidence interval [CI] 1.5-8.0), and giving and receiving oral sex (16 or more; OR 5.4, 95% CI 1.6-17.7 and OR 5.6, 95% CI 1.6-18.7, respectively). Of 343 participants, HPV-free at baseline and with subsequent saliva samples, 87 (25%) acquired new infections over the 24 months. Sixty-eight of 87 people included in the clearance analysis (78%) cleared their oral HPV infections. Clearance was associated with being a nonsmoker (OR 12.7, 95% CI 1.3-122.8), and no previous diagnosis of a sexually transmitted infection (OR 6.2, 95% CI 2.0-19.9). New oral infections with HPV in this sample were not rare. Although most infections were cleared, clearance was not universal suggesting a reservoir of infection exists that might predispose to oropharyngeal carcinogenesis.

Abstract
INTRODUCTION Many parents who choose hypospadias repair for their son experience decisional conflict and regret. The utilization of a shared decision-making process may address the issue of decisional conflict and regret in hypospadias repair by engaging both parents and physicians in decision-making. OBJECTIVE The objective of this study was to develop a theoretical framework of the parental decision-making process about hypospadias surgery to inform the development of a decision aid. STUDY DESIGN We conducted semistructured interviews were conducted with parents of children with hypospadias to explore their role as proxy decision-makers, inquiring about their emotions/concerns, informational needs, and external/internal influences. Interviews were conducted until no new themes were identified, analyzing them iteratively using open, axial, and selective coding. The iterative approach entails a cyclical process of conducting interviews and analyzing transcripts while the data collection process is ongoing. This allows the researcher to make adjustments to the interview guide as necessary based on preliminary data analysis in order to explore themes that emerge from early interviews with parents. Grounded theory methods were used to develop an explanation of the surgical decision-making process. RESULTS Sixteen mothers and one father of seven preoperative and nine postoperative patients (n = 16) with distal (8) and proximal (8) meatal locations were interviewed. Four stages of the surgical decision-making process were identified: (1) processing the diagnosis, (2) synthesizing information, (3) processing emotions and concerns, and (4) finalizing the decision (Extended Summary Figure). Core concepts in each stage of the decision-making process were identified. Primary concerns included anxiety/fear about the child not waking up from anesthesia and their inability to be present in the operating room. Parents incorporated information from the Internet, medical providers, and their social network as they sought to relieve confusion and anxiety while building trust/confidence in their child's surgeon. DISCUSSION The findings of this study contribute to our understanding of decision-making about hypospadias surgery as a complex and multifaceted process. The overall small sample size is typical and expected for qualitative research studies. The primary limitation of the study, however, is the underrepresentation of fathers, minorities, and same-sex couples. CONCLUSIONS This study provides an initial framework of the parental decision-making process for hypospadias surgery that will inform the development of a decision aid. Future stages of decision aid development will focus on recruitment of fathers, minorities, and same-sex couples in order to enrich the perspectives of our work.

Abstract
INTRODUCTION Hypospadias may lead to long-term issues with urination, sexual function and psychosocial well-being. Limited evidence exists regarding the healthcare communication preferences of male adolescents regarding sensitive topics. OBJECTIVE The purpose of this qualitative study was to explore the healthcare communication preferences of male adolescents regarding sensitive topics (e.g. urinary and sexual issues) and engage them in the initial stages of development of a patient-centered outcome tool for adolescents with a history of hypospadias repair. STUDY DESIGN A multidisciplinary team with communication design expertise, pediatric urology experts, and health services researchers developed a self-reported toolkit for adolescent patients who had hypospadias repair as children. The toolkit featured short writing/diagramming exercises and scales to facilitate participant reflections about genital appearance, urination, sexual function, and psychosocial well-being. We recruited students from two local high schools for two focus groups to obtain feedback about the usability/acceptability of the toolkit's appearance/content. We inquired about language preferences and preferred format and/or setting for sharing sensitive information with researchers. The focus groups were audio recorded, professionally transcribed, checked for accuracy, and analyzed by two coders using qualitative content analysis. Major themes and subthemes were identified, and representative quotes were selected. RESULTS We conducted two focus groups in January 2018 with 33 participants, aged 14-18 years. Participants preferred language that would make patients feel comfortable and serious, clinical language rather than slang terms/sexual humor (Extended Summary Table). They recommended avoidance of statements implying that something is wrong with a patient or statements that would pressure the patient into providing answers. They suggested fill-in-the-blank and open-ended responses to encourage freedom of expression and colorful graphics to de-emphasize the test-like appearance of the toolkit. Most participants preferred a toolkit format to a one-on-one interview to discuss sensitive topics such as urinary or sexual issues. Participants would prefer either a male interviewer or would like to have a choice of interviewer gender for individual qualitative interviews, and they recommended a focus group leader with a history of hypospadias repair. DISCUSSION This study provides a rich description of a group of male high school students' experiences with healthcare providers and researchers. Its qualitative design limits generalizability, and our findings may not be similar to those of adolescents with a history of hypospadias repair. CONCLUSION We used focus group feedback on the toolkit prototype to refine the tool for use in a future study of adolescents with a history of hypospadias repair.

Abstract
Abstract
Objective
The Global Neuropsychological Assessment (GNA) is an 18-minute cognitive test battery with seven subtests that is being translated into multiple languages and standardized worldwide. This study seeks to evaluate the GNA’s ability to discriminate patients from healthy controls.
Data Selection
We are recruiting adults who are referred to the Johns Hopkins Medical Psychology Clinic for neuropsychological assessment, along with caregivers or family members who accompany them for this ongoing study. We have administered the GNA to 10 patients with mild cognitive impairment or another disorder and 22 healthy controls to date.
Data Synthesis
Patients and healthy controls did not differ on age, sex, or years of education.Independent samples t-tests showed that patients performed worse than healthy controls (p < 0.05) on 14 measures derived from five of seven GNA subtests. These included measures of episodic memory, processing speed, semantic verbal fluency, set-switching, and spatial working memory. Cohen’s d effect sizes of 1.0 to 2.2 were observed. The groups did not differ on tests of digit repetition or an anxiety/depression screener (Patient Health Questionnaire-4) although these revealed small to medium group differences (Cohen’s ds = 0.27 to 0.71) as well.
Conclusions
Five of seven GNA subtests effectively discriminated controls from patients with mixed cognitive disorders. If effect sizes found for the other two GNA subtests persist, they also will show significant group differences as the sample sizes increase. In related studies, we are examining inter-form equivalence and other psychometric properties of the GNA.

Abstract
OBJECTIVE We tested the ability of a type 1 diabetes (T1D) genetic risk score (GRS) to predict progression of islet autoimmunity and T1D in at-risk individuals. RESEARCH DESIGN AND METHODS We studied the 1,244 TrialNet Pathway to Prevention study participants (T1D patients' relatives without diabetes and with one or more positive autoantibodies) who were genotyped with Illumina ImmunoChip (median [range] age at initial autoantibody determination 11.1 years [1.2-51.8], 48% male, 80.5% non-Hispanic white, median follow-up 5.4 years). Of 291 participants with a single positive autoantibody at screening, 157 converted to multiple autoantibody positivity and 55 developed diabetes. Of 953 participants with multiple positive autoantibodies at screening, 419 developed diabetes. We calculated the T1D GRS from 30 T1D-associated single nucleotide polymorphisms. We used multivariable Cox regression models, time-dependent receiver operating characteristic curves, and area under the curve (AUC) measures to evaluate prognostic utility of T1D GRS, age, sex, Diabetes Prevention Trial-Type 1 (DPT-1) Risk Score, positive autoantibody number or type, HLA DR3/DR4-DQ8 status, and race/ethnicity. We used recursive partitioning analyses to identify cut points in continuous variables. RESULTS Higher T1D GRS significantly increased the rate of progression to T1D adjusting for DPT-1 Risk Score, age, number of positive autoantibodies, sex, and ethnicity (hazard ratio [HR] 1.29 for a 0.05 increase, 95% CI 1.06-1.6; P = 0.011). Progression to T1D was best predicted by a combined model with GRS, number of positive autoantibodies, DPT-1 Risk Score, and age (7-year time-integrated AUC = 0.79, 5-year AUC = 0.73). Higher GRS was significantly associated with increased progression rate from single to multiple positive autoantibodies after adjusting for age, autoantibody type, ethnicity, and sex (HR 2.27 for GRS >0.295, 95% CI 1.47-3.51; P = 0.0002). CONCLUSIONS The T1D GRS independently predicts progression to T1D and improves prediction along T1D stages in autoantibody-positive relatives.

Abstract
The successful implementation of an integrated care pathway (ICP) for any given condition is a challenge. Even more challenging is successful ICP implementation for individuals who have multiple co-morbidities. This is further compounded when there are dual mental health and physical disabilities that require integrated working across multiple disciplines, specialties, institutions and organisations. Anti-NMDA-Receptor encephalitis (aNMDARe) is a relatively new diagnostic entity with patients typically presenting with significant psychiatric symptoms followed by progressive neurological deterioration. In this case series, we describe 3 cases of females with aNMDARe who were referred for complex specialist rehabilitation (CSR) to The National Rehabilitation Hospital. CSR is the total active care of patients with a disabling condition, and their families, by a multi-professional team who have undergone recognised specialist training in rehabilitation, led /supported by a consultant trained and accredited in rehabilitation medicine (RM). These services provide for patients with highly complex rehabilitation needs that are beyond the scope of local services. In these cases, referral to CSR resulted in the construction of a bespoke integrated care pathway (ICP) that transcended the barriers between primary, secondary and tertiary care and across the boundaries of physical and mental health. A care pathway is a complex intervention for the mutual decision-making and organisation of care processes Rehabilitation services acted as the coordinator of services in these cases to ensure implementation of the care plan and to ensure successful transitions of care and supported local specialist and general teams in the management of these complex cases.

Abstract
While Type 2 Diabetes in childhood has become increasingly prevalent throughout the world, in our service we found that only 2% (7/320) of children and adolescents with diabetes aged <16 years had type 2 diabetes. All type 2 subjects were overweight or obese and six of seven were non-Caucasian. Mean age at presentation was 12.8 years. Six patients (85%) had complications, most commonly hypertension. Although Type 2 Diabetes in children remains relatively rare in our cohort, identification of these children is important as management differs from Type 1 Diabetes.

Abstract
INTRODUCTION The use of administrative health data for research has prompted questions about its validity for this purpose. OBJECTIVE/STUDY DESIGN The purpose of this study was to determine the concordance of Pediatric Health Information System (PHIS) perioperative antibiotic charges with the institution's medication administration data for males <10 years old and who underwent outpatient penile/inguinal procedures from July 2013 to March 2015. RESULTS There was 93.9% positive and negative agreement between perioperative antibiotic charges versus administration. The sensitivity and specificity were 96.8% and 87.2%, respectively. The positive and negative predictive values were 94.6% and 92.2%, respectively. CONCLUSION This study indicated strong agreement between PHIS pharmacy charges and medication administration.

Abstract
OBJECTIVES This paper aims to predict childhood obesity after age two, using only data collected prior to the second birthday by a clinical decision support system called CHICA. METHODS Analyses of six different machine learning methods: RandomTree, RandomForest, J48, ID3, Naïve Bayes, and Bayes trained on CHICA data show that an accurate, sensitive model can be created. RESULTS Of the methods analyzed, the ID3 model trained on the CHICA dataset proved the best overall performance with accuracy of 85% and sensitivity of 89%. Additionally, the ID3 model had a positive predictive value of 84% and a negative predictive value of 88%. The structure of the tree also gives insight into the strongest predictors of future obesity in children. Many of the strongest predictors seen in the ID3 modeling of the CHICA dataset have been independently validated in the literature as correlated with obesity, thereby supporting the validity of the model. CONCLUSIONS This study demonstrated that data from a production clinical decision support system can be used to build an accurate machine learning model to predict obesity in children after age two.

Abstract
This study investigated the prevalence and characteristics of Campylobacteraceae including a range of fastidious species in porcine samples. Over a thirteen month period caecal contents (n=402) and pork carcass swabs (n=401) were collected from three pork abattoirs and pork products (n=399) were purchased at point of sale in the Republic of Ireland. Campylobacteraceae isolates were recovered by enrichment, membrane filtration and incubation in antibiotic free media under a modified atmosphere (3% O2, 5% H2, 10% CO2 and 82% N2). Campylobacteraceae isolates were identified as either genus Campylobacter or Arcobacter and then selected species were identified by Polymerase Chain Reaction (PCR). Campylobacteraceae were isolated from 103 (26%) caecal samples, 42 (10%) carcass swabs, and 59 (15%) pork products. Campylobacter coli was the most commonly isolated species found in (37%) all sample types but many fastidious species were also isolated including Campylobacter concisus (10%), Arcobacter butzleri (8%), Campylobacter helveticus (8%), Campylobacter mucosalis (6%), Arcobacter cryaerophilus (3%), Campylobacter fetus subsp. fetus (1%), Campylobacter jejuni subsp. jejuni (1%), Campylobacter lari (0.5%), Campylobacter curvus (0.5%) and Arcobacter skirrowii (0.5%). Among all isolates, 83% contained cadF and 98% flaA. In this study 35% of porcine C. coli were resistant to ciprofloxacin but none of the fastidious species demonstrated any resistance to this drug. The level of resistance to erythromycin was very high (up to 100%) in C. concisus and C. helveticus and this is a real concern as this is the current empiric drug of choice for treatment of severe gastroenteritic Campylobacter infections. The study shows that there is a much wider range of fastidious Campylobacteraceae present in porcine samples than previously assumed with C. concisus the second most common species isolated. The majority of fastidious Campylobacteraceae isolates obtained contained virulence genes and antibiotic resistance indicating potential public health significance.

Abstract
BACKGROUND Impacted ureteric stones can pose a treatment challenge due to the high level of failure of ESWL and endourological approaches. Laparoscopic ureterolithotomy can provide a safe and successful alternative to these and open, invasive procedures. METHODS Interval laparoscopic ureterolithtomy was carried out following placement of a percutaneous nephrostomy. This was performed through an trans-peritoneal approach with the ureterotomy closed by intracorporeal suturing and placement of a JJ stent without the need for an abdominal wound drain. CONCLUSION Laparoscopic ureterolithotomy is a safe, minimally invasive method of managing large, impacted ureteric stones with minimal associated patient morbidity.

Abstract
The first cases of equine influenza (EI) in Australia were reported in late August 2007. By 14 March 2008, provisional freedom from EI was declared and in December 2008 Australia was officially declared EI-free, 12 months after the last reported clinical case. Containment, and ultimate eradication, of EI was achieved through a combination of movement restrictions, zoning, vaccination and enhanced biosecurity measures that drew on the resources and expertise of industry and state and federal governments. Through these measures, the EI outbreak, which peaked in October 2007, was contained to just 3% of Australia, with no new cases reported after 9 December 2007, just four months after the outbreak began.

Abstract
This Letter presents the first measurement of event-by-event fluctuations of the elliptic flow parameter v(2) in Au+Au collisions at square root(s(NN))=200 GeV as a function of collision centrality. The relative nonstatistical fluctuations of the v(2) parameter are found to be approximately 40%. The results, including contributions from event-by-event elliptic flow fluctuations and from azimuthal correlations that are unrelated to the reaction plane (nonflow correlations), establish an upper limit on the magnitude of underlying elliptic flow fluctuations. This limit is consistent with predictions based on spatial fluctuations of the participating nucleons in the initial nuclear overlap region. These results provide important constraints on models of the initial state and hydrodynamic evolution of relativistic heavy ion collisions.

Abstract
A measurement of two-particle correlations with a high transverse momentum trigger particle (p(T)(trig) > 2.5 GeV/c) is presented for Au+Au collisions at square root(s(NN)) = 200 GeV over the uniquely broad longitudinal acceptance of the PHOBOS detector (-4 < Delta eta < 2). A broadening of the away-side azimuthal correlation compared to elementary collisions is observed at all Delta eta. As in p+p collisions, the near side is characterized by a peak of correlated partners at small angle relative to the trigger particle. However, in central Au+Au collisions an additional correlation extended in Delta eta and known as the "ridge" is found to reach at least |Delta eta| approximately = 4. The ridge yield is largely independent of Delta eta over the measured range, and it decreases towards more peripheral collisions. For the chosen (p(T)(trig) cut, the ridge yield is consistent with zero for events with less than roughly 100 participating nucleons.

Abstract
Chemical imaging by confocal Raman microscopy has been used for the visualization of the cellulose and lignin distribution in wood cell walls. Lignin reduction in wood can be achieved by, for example, transgenic suppression of a monolignol biosynthesis gene encoding 4-coumarate-CoA ligase (4CL). Here, we use confocal Raman microscopy to compare lignification in wild type and lignin-reduced 4CL transgenic Populus trichocarpa stem wood with spatial resolution that is sub-microm. Analyzing the lignin Raman bands in the spectral region between 1,600 and 1,700 cm(-1), differences in lignin signal intensity and localization are mapped in situ. Transgenic reduction of lignin is particularly pronounced in the S2 wall layer of fibers, suggesting that such transgenic approach may help overcome cell wall recalcitrance to wood saccharification. Spatial heterogeneity in the lignin composition, in particular with regard to ethylenic residues, is observed in both samples.

Abstract
A national public survey on public perceptions of prion disease risk in Canada was conducted from October to December 2007. The survey aimed at documenting the public's perceptions of prion diseases, within the broader context of food safety, in establishing parameters of risk acceptability. It also documented the public's perceptions of prion diseases in delineating social values and ethics that can guide Canada's future policies on prion disease risk management. In addition, the survey served to establish baseline data against which to monitor the evolution of the public's views on and understanding of this important risk issue. In total, 1517 Canadians were randomly selected to be representative of the adult population by region, age, and gender, as per the 2001 Census. This study presents descriptive findings from the survey regarding perceived risk, perceived control, uncertainty, sources of information, trust and knowledge, and beliefs pertaining to bovine spongiform encephalopathy (BSE). The survey data reveal that Canadians do not perceive mad cow disease as a salient risk but consider it more of an economic, political, social, and foreign trade issue than a public health one. Canadians are somewhat prepared to pay a premium to have a safer food supply, but not to the same extent that they desire extra measures pertaining to BSE risk management. In the context of increasing accountability in risk management decisions about food safety and population health issues, it is important to understand the way Canadians perceive such matters and identify their information needs and the factors that influence the acceptability of risks and of risk management policies.
