Abstract
BACKGROUND Cirrhosis is associated with sarcopaenia and fat wasting, which drive decompensation and mortality. Currently, nutritional status, through body composition assessment, is not routinely monitored in outpatients. Given the deleterious outcomes associated with poor nutrition in decompensated cirrhosis, there is a need for remotely monitoring this to optimise community care. METHODS A retrospective analysis was conducted on patients monitored remotely with digital sensors post hospital discharge, to assess outcomes and indicators of new cirrhosis complications. 15 patients had daily fat mass measurements as part of monitoring over a median 10 weeks, using a Withing's bioimpedance scale. The Clinical Frailty Score (CFS) was used to assess frailty and several liver disease severity scores were assessed. RESULTS 73.3% (11/15) patients were male with a median age of 63 (52-68). There was a trend towards more severe liver disease based on CLIF-Consortium Acute Decompensation (CLIF-C AD) scores in frail patients vs. those not frail (53 vs 46, p = 0.072). When the cohort was split into patients who gained fat mass over 8 weeks vs. those that lost fat mass, the baseline CLIF-C AD scores and WBC were significantly higher in those that lost fat (58 vs 48, p = 0.048 and 11.2 × 109 vs 4.7 × 109, p = 0.031). CONCLUSIONS This proof-of-principle study shows feasibility for remote monitoring of fat mass and nutritional reserve in decompensated cirrhosis. Our results suggest fat mass is associated with greater severity of acute decompensation and may serve as an indicator of systemic inflammatory response. Further prospective studies are required to validate this digital biomarker.

Abstract
Racism continues to drive health disparities between Indigenous and non-Indigenous peoples in Canada. This study focuses on racism experienced by young Indigenous people who have used drugs in British Columbia (BC), and predictors of interpersonal racism. Cedar Project is a community-governed cohort study involving young Indigenous people who use drugs in Vancouver and Prince George, BC. This cross-sectional study included data collected between August 2015-October 2016. The Measure of Indigenous Racism Experiences (MIRE) scale was used to assess experiences of interpersonal racism across 9 unique settings on a 5-point Likert scale, collapsing responses into three categories (none/low/high). Multinomial logistic regression models were used to examine associations between key variables and interpersonal racism. Among 321 participants, 79% (n = 255) experienced racism in at least one setting. Thirty two percent (n = 102) experienced high interpersonal racism from police, governmental agencies (child 'welfare', health personnel), and in public settings. Ever having a child apprehended (AOR:2.76, 95%CI:1.14-6.65), probable post-traumatic stress (AOR:2.64; 95%CI:1.08-6.46), trying to quit substances (AOR:3.69; 95%CI:1.04-13.06), leaving emergency room without receiving treatment (AOR:3.05; 95%CI:1.22-7.64), and having a traditional language spoken at home while growing up (AOR:2.86; 95%CI:1.90-6.90) were associated with high interpersonal racism. Among women, experiencing high interpersonal racism was more likely if they lived in Prince George (AOR:3.94; 95%CI:1.07-14.50), ever had a child apprehended (AOR:5.09; 95%CI:1.50-17.30), and had probable post-traumatic stress (AOR:5.21; 95%CI:1.43-18.95). Addressing racism experienced by Indigenous peoples requires immediate structural systemic, and interpersonal anti-racist reforms.

Abstract
BACKGROUND Between 1883 and 1996, thousands of Indigenous children were apprehended into Canada's Residential School System. Survivors and their descendants have testified to genocidal harms caused across generations. Yet, Indigenous Peoples continue to exist and resist through inherent resilience described by intergenerational survivors in this paper. OBJECTIVE This article focuses on stories demonstrating the strength, power, and resilience of intergenerational residential school survivors. PARTICIPANTS & SETTING Cedar Project is an Indigenous-led cohort study that began as a HIV/AIDS response and contributes to healing among young Indigenous people who use drugs in British Columbia, Canada. It is governed by the Cedar Project Partnership, an Indigenous body of Elders, leaders, and health/social services experts. METHODS We present qualitative research involving in-depth interviews carried out with Cedar participants who have experienced significant and complex adversities including childhood maltreatment and illicit drug use. Woven throughout, Indigenous scholars who are themselves intergenerational (children and grandchildren) of residential school survivors provide first-person reflections on the findings. RESULTS Analysis focused on narratives of resilience and resistance to stresses of intergenerational traumas across three broad themes: working to break cycles of intergenerational trauma; foundations of resilience and making positive changes and; hopes and dreams. CONCLUSIONS Findings establish deeper understanding of processes that enable young people to cope with stresses of intergenerational traumas while facing institutional and structural barriers to wellness. Reflections provide context about how intergenerational experiences intersect with challenges that young intergenerational survivors continue to face. We highlight pathways to healing and sources of strength that inform recommendations for wellness.

Abstract
In the intravenous iron therapy to treat iron deficiency anaemia in patients undergoing major abdominal surgery (PREVENTT) trial, the use of intravenous iron did not reduce the need for blood transfusion or reduce patient complications or length of hospital stay. As part of the trial protocol, serum was collected at randomisation and on the day of surgery. These samples were analysed in a central laboratory for markers of iron deficiency. We performed a secondary analysis to explore the potential interactions between pre-operative markers of iron deficiency and intervention status on the trial outcome measures. Absolute iron deficiency was defined as ferritin <30 μg.l-1 ; functional iron deficiency as ferritin 30-100 μg.l-1 or transferrin saturation < 20%; and the remainder as non-iron deficient. Interactions were estimated using generalised linear models that included different subgroup indicators of baseline iron status. Co-primary endpoints were blood transfusion or death and number of blood transfusions, from randomisation to 30 days postoperatively. Secondary endpoints included peri-operative change in haemoglobin, postoperative complications and length of hospital stay. Most patients had iron deficiency (369/452 [82%]) at randomisation; one-third had absolute iron deficiency (144/452 [32%]) and half had functional iron deficiency (225/452 [50%]). The change in pre-operative haemoglobin with intravenous iron compared with placebo was greatest in patients with absolute iron deficiency, mean difference 8.9 g.l-1 , 95%CI 5.3-12.5; moderate in functional iron deficiency, mean difference 2.8 g.l-1 , 95%CI -0.1 to 5.7; and with little change seen in those patients who were non-iron deficient. Subgroup analyses did not suggest that intravenous iron compared with placebo reduced the likelihood of death or blood transfusion at 30 days differentially across subgroups according to baseline ferritin (p = 0.33 for interaction), transferrin saturation (p = 0.13) or in combination (p = 0.45), or for the number of blood transfusions (p = 0.06, 0.29, and 0.39, respectively). There was no beneficial effect of the use of intravenous iron compared with placebo, regardless of the metrics to diagnose iron deficiency, on postoperative complications or length of hospital stay.

Abstract
BACKGROUND Guidelines recommend to consider excluding non-ST-segment elevation myocardial infarction (NSTEMI) when high-sensitivity cardiac troponin is below the limit of quantification and a single blood sample is taken > 6 h after the onset of chest pain. The aim of our study was to assess such exclusion when a single blood sample was taken 3-6 h after the onset of permanent chest pain. METHODS This observational study included consecutive patients admitted into the emergency room of our hospital with chest pain and suspected NSTEMI, with non-contributive electrocardiograms and a single high-sensitivity cardiac troponin I (hs-cTnI) blood sample taken 3-6 h after the onset of chest pain and hs-cTnI < 4 ng/l (Abbott Diagnostic). Clinical follow-up was undertaken 1 month after admission. RESULTS The mean age of the 432 patients was 48.5 ± 5.6 years and 51% were male. Based on a clinical algorithm, the pre-test probability of NSTEMI was low in 70%, and intermediate in 21% of patients. Among 419 patients with available 1-month follow-up data, there were no myocardial infarctions or deaths. Thirty-eight patients (9%) were admitted into hospital but none for cardiac reasons. CONCLUSIONS Our results suggest that exclusion of NSTEMI in patients with a non-contributive electrocardiogram and a single "negative" troponin test in a blood sample taken 3-6 h after the onset of symptoms is valid.

Abstract
Native extracellular matrix (ECM) possesses the biochemical cues to promote cell survival. However, decellularized, the ECM loses its cell supporting mechanical integrity. We report, here, a novel biohybrid vascular graft of polycaprolactone (PCL), poliglecaprone (PGC) incorporated with human biomatrix as functional materials for vascular tissue interfacing by electrospinning, thus harnessing the biochemical cues from the ECM and the mechanical integrity of the polymer blends. The fabricated fibro-porous tubular small diameter graft (i.d. = 4 mm) from polymer blend was coated with a cocktail of collagenous matrix derived from human placenta called HuBiogel™. The compositional, morphological, and mechanical properties of graft were measured and compared with a non-coated tubular PCL/PGC graft using Fourier Transform infrared spectroscopy (FTIR), x-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM). BCA assay was used to calculate the protein content and coating-uniformity throughout the hybrid graft. Mechanical properties such as tensile strength (1.6 MPa), Young's modulus (2.4 MPa), burst pressure (>1900 mmHg), and suture retention strength (2.3 N) of hybrid graft were found to be comparable to native blood vessels. Protein coating has improved the hydrophilicity and the biocompatibility (cell viability and cell-attachment) enhanced with human umbilical vein endothelial cells (HUVECs) seeded in vitro onto the lumen layer of the graft over two weeks. The overall results promise this new biohybrid graft to be a potential candidate for vascular tissue interface and regeneration.

Abstract
Background Indigenous leaders continue to be concerned about high rates of HIV and barriers to HIV treatment among young Indigenous people involved in substance use. Growing evidence suggests that using mobile phones for health (mHealth) may be a powerful way to support connection with health services, including HIV prevention and treatment. Objective This study examined the patterns of mobile phone ownership and use among young Indigenous people who have used drugs living with or vulnerable to HIV and explored the acceptability of mHealth to support access to health care in this population. Methods The Cedar Project is a cohort study involving young Indigenous people who have used drugs in Vancouver and Prince George, British Columbia. This mixed methods exploratory study involved 131 Cedar Project participants enrolled in our WelTel mHealth program. At enrollment, participants completed a questionnaire related to mobile phone use and interest in mHealth. Data were linked to Cedar Project questionnaires and serodata. We present comparative statistics (quantitative) and results of a rapid thematic analysis (qualitative) related to mobile phone patterns and interest in receiving mHealth. Results Less than half of the participants (59/130; 45.4%) reported owning a phone. Among those with a phone, the majority owned a smartphone (46/59; 78%). Most participants with a phone reported having an unlimited texting plan (39/55; 71%), using the internet on their phone (44/59; 75%), and texting daily (44/55; 80%). A majority reported that using a mobile phone for health would be invaluable (120/130; 92.3%). There were no differences in mHealth acceptance between participants who owned a phone and those who did not (P>.99). All but one participant living with HIV felt using a mobile phone would be helpful for their health, while a small proportion of HIV-negative participants remained unsure (1.9% vs 11.7%; P=.047). In response to open-ended questions asking why using a mobile phone may be helpful for health, participants identified a diverse set of anticipated benefits: (1) connection for emotional, mental, and spiritual support, (2) connection to family, (3) staying in touch and/or being reachable, (4) overcoming current barriers to phone use, (5) convenience, privacy, and safety, and (6) access to health care and emergency services. Conclusions We observed high acceptance and interest in using mobile phone technology for health despite low rates of personal mobile phone connectivity among young Indigenous people who have used drugs living with and vulnerable to HIV in British Columbia, Canada. Mobile phones were viewed as a way to support connections and relationships that are seen as critical to health and well-being among young Indigenous people in this study. Findings may be useful for health care providers preparing to scale up mHealth programs to support HIV prevention and treatment in this population.

Abstract
Monte Carlo (MC) simulation is widely used in gamma-ray spectrometry, however, its implementation is not always easy and can provide erroneous results. The present action provides a benchmark for several MC software for selected cases. The examples are based on simple geometries, two types of germanium detectors and four kinds of sources, to mimic eight typical measurement conditions. The action outputs (input files and efficiency calculation results, including practical recommendations for new users) are made available on a dedicated webpage.

Abstract
PURPOSE To ascertain the impact of altering cylinder (cyl) power and axis on vision in astigmatism. METHODS In a prospective, randomized, participant-masked, crossover clinical trial, 28 astigmatic participants were tested for the following conditions on different days: full sphero-cyl correction and undercorrection by 0.25, 0.50, and 0.75 DC while maintaining spherical equivalence. Axis was also misaligned between -30° and +30°, in 10° steps. For each configuration, monocular high- and low-contrast visual acuities (HCVA, LCVA) were measured at 6 m, and participants rated vision clarity (1-10), vision satisfaction (1-10), and vision acceptability (yes/no). Linear mixed models were used to compare visual performance in the overall group and in low, medium, and high cyl subgroups. RESULTS Undercorrecting cyl power affected all groups equally (P≥0.073). Undercorrection by 0.75 DC was significantly different to full cyl power for all variables (P≤0.007), while 0.25 DC undercorrection did not cause any significant decreases (P>0.05). Undercorrection by 0.50 DC was significantly different to full cyl power for HCVA (P=0.006, however not clinically significant) and vision acceptability (P=0.034). Axis misalignment affected the cyl groups differently (P<0.001), with the greatest impact in the high cyl group, followed by the medium then the low-cyl group. Misalignment by ±30° caused significant decreases in almost all cases (P≤0.003), while misalignments by ±10° or ±20° caused significant decreases for some cyl groups and test variables. CONCLUSION Undercorrection of cyl by ≤0.50 DC while maintaining spherical equivalence has no significant effect on HCVA, LCVA, vision clarity, and vision satisfaction, while the amount of axis misalignment that can be tolerated is dependent on the cyl power. These results may have practical ophthalmic applications, such as reducing the total number of stock keeping units of toric contact lenses.

Abstract
BACKGROUND Incorrect inhaler technique is a common cause of poor asthma control. This two-phase pragmatic study evaluated inhaler technique mastery and maintenance of mastery with DuoResp® (budesonide-formoterol [BF]) Spiromax® compared with Symbicort® (BF) Turbuhaler® in patients with asthma who were receiving inhaled corticosteroids/long-acting β2-agonists. METHODS In the initial cross-sectional phase, patients were randomized to a 6-step training protocol with empty Spiromax and Turbuhaler devices. Patients initially demonstrating ≥1 error with their current device, and then achieving mastery with both Spiromax and Turbuhaler (absence of healthcare professional [HCP]-observed errors), were eligible for the longitudinal phase. In the longitudinal phase, patients were randomized to BF Spiromax or BF Turbuhaler. Co-primary endpoints were the proportions of patients achieving device mastery after three training steps and maintaining device mastery (defined as the absence of HCP-observed errors after 12 weeks of use). Secondary endpoints included device preference, handling error frequency, asthma control, and safety. Exploratory endpoints included assessment of device mastery by an independent external expert reviewing video recordings of a subset of patients. RESULTS Four hundred ninety-three patients participated in the cross-sectional phase, and 395 patients in the longitudinal phase. In the cross-sectional phase, more patients achieved device mastery after three training steps with Spiromax (94%) versus Turbuhaler (87%) (odds ratio [OR] 3.77 [95% confidence interval (CI) 2.05-6.95], p < 0.001). Longitudinal phase data indicated that the odds of maintaining inhaler mastery at 12 weeks were not statistically significantly different (OR 1.26 [95% CI 0.80-1.98], p = 0.316). Asthma control improved in both groups with no significant difference between groups (OR 0.11 [95% CI -0.09-0.30]). An exploratory analysis indicated that the odds of maintaining independent expert-verified device mastery were significantly higher for patients using Spiromax versus Turbuhaler (OR 2.11 [95% CI 1.25-3.54]). CONCLUSIONS In the cross-sectional phase, a significantly greater proportion of patients using Spiromax versus Turbuhaler achieved device mastery; in the longitudinal phase, the proportion of patients maintaining device mastery with Spiromax versus Turbuhaler was similar. An exploratory independent expert-verified analysis found Spiromax was associated with higher levels of device mastery after 12 weeks. Asthma control was improved by treatment with both BF Spiromax and BF Turbuhaler. TRIAL REGISTRATION EudraCT 2013-004630-14 (registration date 23 January 2014); NCT02570425 .

Abstract
Introduction Ventolin Nebules® (reference product; GlaxoSmithKline) was the first licensed nebulizer solution containing the rapid-onset, short-acting β2-agonist salbutamol. Salbutamol Steri-Neb™ (comparator; Teva Pharmaceuticals, Inc.) has the same chemical composition as the reference product. This study evaluated whether the effectiveness of the comparator is non-inferior to the reference product alongside concomitant medications during real-life clinical management of COPD exacerbations. Safety in terms of adverse events (AEs) was also examined. Methods This matched (1:1) historical cohort study evaluated data from 2 UK primary care databases on patients prescribed the salbutamol comparator or reference. The study included a 1-year baseline period, starting 1 year before the index prescription date, and 1-year outcome period. Cohorts were matched for baseline COPD respiratory medications. The primary outcome was analysis of non-inferiority for the comparator versus reference product for the rate of moderate and severe COPD exacerbations. Non-inferiority was satisfied if the 95% confidence interval (CI) upper limit for mean differences in proportions between treatments was <15%. Secondary outcomes were examined through rate ratios (RR) of severe exacerbations and AEs. Results After matching, 1191 patients were included in each cohort. Adjusted upper 95% CI for the difference in proportion of patients experiencing moderate or severe exacerbations between comparator and reference groups was 0.032 (3.2%), demonstrating non-inferiority. No significant differences were observed in rates of moderate and severe exacerbations (RR: 1.00; 95% CI: 0.91, 1.10), severe exacerbations (RR: 0.76; 95% CI: 0.49, 1.17), or AEs (RR: 0.98; 95% CI: 0.78, 1.22) after adjusting for baseline confounders. No significant differences across cohorts were observed for rates of any AE or death. Conclusion This matched cohort study of real-life management of COPD patients supports the salbutamol comparator as non-inferior to the reference product, providing an effective treatment alternative for COPD exacerbations. Comparator and reference safety profiles were similar.

Abstract
Batrachochytrium salamandrivorans (Bsal) poses a major threat to amphibian, and more specifically caudata, diversity. Bsal is currently spreading through Europe, and mitigation measures aimed at stopping its spread and preventing its introduction into naïve environments are urgently needed. Screening for presence of Bsal and diagnosis of Bsal-induced disease in amphibians are essential core components of effective mitigation plans. Therefore, the aim of this study was to present an overview of all Bsal diagnostic tools together with their limitations and to suggest guidelines to allow uniform interpretation. Here, we investigate the use of different diagnostic tools in post-mortem detection of Bsal and whether competition between Bd and Bsal occurs in the species-specific Bd and Bsal duplex real-time PCR. We also investigate the diagnostic sensitivity, diagnostic specificity and reproducibility of the Bsal real-time PCR and show the use of immunohistochemistry in diagnosis of Bsal-induced chytridiomycosis in amphibian samples stored in formaldehyde. Additionally, we have drawn up guidelines for the use and interpretation of the different diagnostic tools for Bsal currently available, to facilitate standardization of execution and interpretation.

Abstract
BACKGROUND Young Indigenous people, particularly those involved in the child welfare system, those entrenched in substance use and those living with HIV or hepatitis C, are dying prematurely. We report mortality rates among young Indigenous people who use drugs in British Columbia and explore predictors of mortality over time. METHODS We analyzed data collected every 6 months between 2003 and 2014 by the Cedar Project, a prospective cohort study involving young Indigenous people who use illicit drugs in Vancouver and Prince George, BC. We calculated age-standardized mortality ratios using Indigenous and Canadian reference populations. We identified predictors of mortality using time-dependent Cox proportional hazard regression. RESULTS Among 610 participants, 40 died between 2003 and 2014, yielding a mortality rate of 670 per 100 000 person-years. Young Indigenous people who used drugs were 12.9 (95% confidence interval [CI] 9.2-17.5) times more likely to die than all Canadians the same age and were 7.8 (95% CI 5.6-10.6) times more likely to die than Indigenous people with Status in BC. Young women and those using drugs by injection were most affected. The leading causes of death were overdose (n = 15 [38%]), illness (n = 11 [28%]) and suicide (n = 5 [12%]). Predictors of mortality included having hepatitis C at baseline (adjusted hazard ratio [HR] 2.76, 95% CI 1.47-5.16), previous attempted suicide (adjusted HR 1.88, 95% CI 1.01-3.50) and recent overdose (adjusted HR 2.85, 95% CI 1.00-8.09). INTERPRETATION Young Indigenous people using drugs in BC are dying at an alarming rate, particularly young women and those using injection drugs. These deaths likely reflect complex intersections of historical and present-day injustices, substance use and barriers to care.

Abstract
Chronic obstructive pulmonary disease (COPD), a complex progressive disease, is currently the third leading cause of death worldwide. One recommended treatment option is fixed-dose combination therapy of an inhaled corticosteroid (ICS)/long-acting β-agonist. Clinical trials suggest pressurized metered-dose inhalers (pMDIs) and dry powder inhalers (DPIs) show similar efficacy and safety profiles in COPD. Real-world observational studies have shown that combination therapy has significantly greater odds of achieving asthma control when delivered via pMDIs. Our aim was to compare effectiveness, in terms of moderate/severe COPD exacerbations and long-acting muscarinic antagonist (LAMA) prescriptions, for COPD patients initiating fluticasone propionate (FP)/salmeterol xinafoate (SAL) via pMDI versus DPI at two doses of FP (500 and 1,000 μg/d) using a real-life, historical matched cohort study. COPD patients with ≥2 years continuous practice data, ≥2 prescriptions for FP/SAL via pMDI/DPI, and no prescription for ICS were selected from the Optimum Patient Care Research Database. Patients were matched 1:1. Rate of moderate/severe COPD exacerbations and odds of LAMA prescription were analyzed using conditional Poisson and logistic regression, respectively. Of 472 patients on 500 μg/d, we observed fewer moderate/severe exacerbations in patients using pMDI (99 [42%]) versus DPI (115 [49%]) (adjusted rate ratio: 0.71; 95% confidence interval: 0.54, 0.93), an important result since the pMDI is not licensed for COPD in the UK, USA, or China. At 1,000 μg/d, we observed lower LAMA prescription for pMDI (adjusted odds ratio: 0.71; 95% confidence interval: 0.55, 0.91), but no difference in exacerbation rates, potentially due to higher dose of ICS overcoming low lung delivery from the DPI.

Abstract
BACKGROUND While the patient and public involvement (PPI) evidence base has expanded over the past decade, the quality of reporting within papers is often inconsistent, limiting our understanding of how it works, in what context, for whom, and why. OBJECTIVE To develop international consensus on the key items to report to enhance the quality, transparency, and consistency of the PPI evidence base. To collaboratively involve patients as research partners at all stages in the development of GRIPP2. METHODS The EQUATOR method for developing reporting guidelines was used. The original GRIPP (Guidance for Reporting Involvement of Patients and the Public) checklist was revised, based on updated systematic review evidence. A three round Delphi survey was used to develop consensus on items to be included in the guideline. A subsequent face-to-face meeting produced agreement on items not reaching consensus during the Delphi process. RESULTS One hundred forty-three participants agreed to participate in round one, with an 86% (123/143) response for round two and a 78% (112/143) response for round three. The Delphi survey identified the need for long form (LF) and short form (SF) versions. GRIPP2-LF includes 34 items on aims, definitions, concepts and theory, methods, stages and nature of involvement, context, capture or measurement of impact, outcomes, economic assessment, and reflections and is suitable for studies where the main focus is PPI. GRIPP2-SF includes five items on aims, methods, results, outcomes, and critical perspective and is suitable for studies where PPI is a secondary focus. CONCLUSIONS GRIPP2-LF and GRIPP2-SF represent the first international evidence based, consensus informed guidance for reporting patient and public involvement in research. Both versions of GRIPP2 aim to improve the quality, transparency, and consistency of the international PPI evidence base, to ensure PPI practice is based on the best evidence.

Abstract
Objective The objective of this study was to determine whether the effectiveness of budesonide comparator is non-inferior to budesonide reference in the prevention of asthma exacerbations. Asthma-related hospitalizations and safety were also examined. Methods This study used a matched, historic cohort design. Data were drawn from the Clinformatics™ Data Mart US claims database and included a 1-year baseline, starting 1 year before the index prescription date, and a 1-year outcome period. Patients received budesonide comparator or reference treatment. The primary outcome was the rate of asthma exacerbations. Non-inferiority for budesonide comparator vs budesonide reference was established if the 95% confidence interval (CI) upper limit of mean difference in proportions between treatments was <15%. Secondary outcomes examined rate of asthma-related hospitalizations and adverse events (AEs). Results The budesonide comparator and reference-matched cohorts each included 3109 patients. The adjusted upper 95% CI for the difference in proportions of patients experiencing asthma exacerbations was 0.035 (3.5%), demonstrating non-inferiority. Cohorts did not significantly differ in the rate of asthma exacerbations (adjusted rate ratio [RR]=1.04, 95% CI: 0.95–1.14) or rate of asthma-related hospitalizations (adjusted RR=1.10, 95% CI: 0.99–1.24) after adjusting for baseline confounders. No asthma exacerbations occurred during the outcome period in 72.9% of budesonide comparator patients and 71.8% of budesonide reference patients. No asthma-related hospitalizations occurred in 77.9% of patients in the budesonide comparator cohort and 79.0% of patients in the budesonide reference cohort. The most frequent AEs were throat irritation (≤0.4% of patients) and hoarseness/dysphonia (0.02% of patients). AEs did not significantly differ between treatment cohorts. Conclusion In this real-life study, non-inferiority of the budesonide comparator vs reference was met for the primary end point of asthma exacerbation rates. Asthma-related hospitalization and AE rates did not differ between the two treatment cohorts. The budesonide comparator is an effective and safe treatment alternative for asthma exacerbations.

Abstract
Samarium doped sodium bismuth silicate glass was synthesized using the melt quenching method. Detailed optical spectroscopic studies of the glassy material were carried out in the UV-Vis-NIR spectral range. Using the optical absorption spectra Judd-Ofelt (JO) parameters are derived. The calculated values of the JO parameters are utilized in evaluating the various radiative parameters such as electric dipole line strengths (Sed), radiative transition probabilities (Arad), radiative lifetimes (τrad), fluorescence branching ratios (β) and the integrated absorption cross- sections (σa) for stimulated emission from various excited states of Sm3+‡ ion. The principal fluorescence transitions are identified by recording the fluorescence spectrum. Our analysis revealed that the novel glassy system has the optimum values for the key parameters viz. spectroscopic quality factor, optical gain, stimulated emission cross section and quantum efficiency, which are required for a high performance optical amplifier. Calculated chromaticity co-ordinates (0.61, 0.38) also confirm its application potential in display devices.

Abstract
BACKGROUND Despite successes in preventing and treating HIV, Indigenous people in Canada continue to face disproportionately high rates of HIV infection. Programs that support healing from lifetime trauma, support connection to culture, and reduce drug-related harms are critical to preventing HIV among young Indigenous people who use drugs. The Cedar Project WelTel mHealth intervention proposed here is a structured mobile-phone initiative to connect young Indigenous people who use drugs with Cedar Case Managers in a community-based setting. The intervention consists of a package of supports, including a mobile phone and cellular plan, weekly two-way text messaging, and support from Cedar Case Managers. METHODS The Cedar Project WelTel mHealth study is a multi-site Zelen pre-randomized trial to measure the effect of a two-way supportive text-message intervention to reduce HIV vulnerability among young Indigenous people who use illicit drugs in two Canadian cities. The trial is nested within the Cedar Project, an ongoing cohort study addressing HIV and hepatitis C vulnerability among young Indigenous people who use drugs in Vancouver and Prince George, British Columbia. The Cedar Project Partnership, an independent body of Indigenous Elders, leaders, and health/social service experts, governs all aspects of the study. Two hundred participants will be followed over a 16-month period, with HIV propensity score at 6 months as the primary outcome. Secondary outcomes include HIV propensity at 1 year, HIV risk, resilience, psychological distress, access to drug-related services, and connection to culture measured at 6 months and 1 year. Primary analysis is by intention to treat. DISCUSSION Culturally safe interventions that address barriers to HIV prevention while supporting the strength of young Indigenous people who use drugs are urgently needed. Despite presenting a tremendous opportunity to connect young, highly transient Indigenous people who use drugs to prevention services, supportive two-way mHealth programs have yet to be tested for HIV prevention in a community-based setting with this population.

Abstract
Abstract
Background: Multi-gene panels are widely available for assessing hereditary cancer risk in high risk individuals. Due to the use of these panels, many genetic mutations other than BRCA 1 or 2 can be detected which can potentially affect management. This study presents the results of multi-gene panel testing performed at Beaumont Health System.
Methods:All patients who underwent multi-gene panel testing at Beaumont Health System between November 1, 2012 and January 15, 2015 were included in this study. This cohort consisted of patients who met criteria for genetic testing due to personal or family history. All patients received comprehensive pre and post-test genetic counseling. The panels ranged from 5 to 43 genes associated with risk for breast and other cancers.
Results: 653 multi-gene panel tests were performed. The majority of these consisted of either a 5 gene high risk breast panel (25%), an 18 gene moderate to high risk breast panel (21%), or a 9 gene high risk breast and gynecologic panel (17%). 184 variants of undetermined significance (VUS) were identified with a pooled VUS rate of 28%. Among the commonly used panels, there was a positive correlation between VUS rate and the number of genes included in the panel (r = 0.86, p = 0.01, Range 6% to 70%). A pathogenic mutation was identified in one or more genes in 65 (10%) panels for a total of 67 mutations. Of these, 17 mutations were in BRCA1 or BRCA2 gene. Fifty non-BRCA deleterious mutations were identified with the following frequencies: CHEK2(12), MUTYH(7 monoallelic, 1 biallelic), TP53(4), PTEN(4), ATM(4), MSH6(3), PALB2(3), MSH2(2), CDH1(2), APC(2), NF1(2), BARD1(2), MLH1(1) and PMS2(1). Of these non-BRCA mutations, 41(82%) had a significant impact on management.
Conclusions: Our study demonstrates that multi-gene panel testing identifies several genes that can impact management and would likely not have been discovered by pedigree analysis alone. However, this added detection is associated with a higher VUS rate, especially using larger panels. Further research is needed to better define the role of multi-gene panel testing in high risk patients, with a focus on choosing appropriate genes, understanding the magnitude of cancer risk and delineating impact on management.

Abstract
Epidemiological cut-off values were developed for application to antibiotic susceptibility data for Flavobacterium psychrophilum generated by standard CLSI test protocols. The MIC values for ten antibiotic agents against Flavobacterium psychrophilum were determined in two laboratories. For five antibiotics, the data sets were of sufficient quality and quantity to allow the setting of valid epidemiological cut-off values. For these agents, the cut-off values, calculated by the application of the statistically based normalized resistance interpretation method, were ≤16 mg L(-1) for erythromycin, ≤2 mg L(-1) for florfenicol, ≤0.025 mg L(-1) for oxolinic acid (OXO), ≤0.125 mg L(-1) for oxytetracycline and ≤20 (1/19) mg L(-1) for trimethoprim/sulphamethoxazole. For ampicillin and amoxicillin, the majority of putative wild-type observations were 'off scale', and therefore, statistically valid cut-off values could not be calculated. For ormetoprim/sulphadimethoxine, the data were excessively diverse and a valid cut-off could not be determined. For flumequine, the putative wild-type data were extremely skewed, and for enrofloxacin, there was inadequate separation in the MIC values for putative wild-type and non-wild-type strains. It is argued that the adoption of OXO as a class representative for the quinolone group would be a valid method of determining susceptibilities to these agents.

Abstract
23 Background: New technologies for identifying hereditary predisposition to breast cancer have led to the discovery of novel genes associated with cancer risk. This has prompted re-evaluation of patients who previously tested negative for BRCA1/2 gene mutations, with a possibility of discovering new genes which may impact management. This study reports on the results of retesting patients who previously were negative for BRCA1/2. Methods: Patients who tested negative for BRCA1/2 mutations who had significant personal and family history were referred back to the Cancer Genetics Center between February 1, 2012 and May 30, 2105 for discussion of additional testing. A detailed personal and family history was reviewed, and patients were counseled about the genetics and clinical implications of panel testing for multiple breast cancer genes. Panel testing using next generation sequencing technologies was ordered. Patients were seen in follow up for discussion of results and management. Results: A total of 12 pathogenic mutations were identified during the study period. The genes and frequencies of these mutations were: CHEK2(3), PALB2(3), ATM(2), APC(1), BARD(1), CDH(1), MUTYH(1). There were 33 variants of undetermined significance(VUS) in 27 patients. 5 of these were seen in patients with a known pathogenic mutation; 3 others were later classified as benign. The frequencies of these VUSs were: ATM (9), PALB2(3), BARD1 (3), PTEN(3), PMS2(3), MSH6(2), CHEK2 (1), MYH(1), RAD51(1), BRIP1(2), NF1(1), BMPR1A(1). Of the 46 patients who had their initial BRCA testing and repeat panel testing between February 1, 2012 and May 30, 2015, 6 (13%) tested positive for a pathogenic mutation. Conclusions: This study demonstrates the feasibility and potential clinical benefit of retesting individuals who previously tested negative for BRCA1/2 mutation. This approach had a significant management impact on patients and their families, with a 13% detection rate of pathogenic mutations. The success of retesting is predicated upon an infrastructure of provider and patient education, pre and post genetic counseling and serves as a model for other centers.

Abstract
Aboriginal homelessness is considered to be a result of historic dispossession of traditional territories and forced displacement from community structures. Using data collected from 2005-2010 from the Cedar Project, a cohort of young Aboriginal people who use drugs in two Canadian cities, we examined how residential transience shapes HIV vulnerability. At baseline, 48 of 260 participants (18.5%) reported sleeping in six or more places ('highly transient') in the past six months. Generalized linear mixed models identified associations between high transience and sex and drug related HIV vulnerabilities. Transience was independently associated with sex work (AOR:3.52, 95%CI:2.06, 6.05); sexual assault (AOR:2.48, 95%CI:1.26, 4.86); injection drug use (AOR:4.54, 95%CI:2.71, 7.61); daily cocaine injection (AOR:2.16, 95%CI:1.26, 3.72); and public injection (AOR:2.87, 95%CI:1.65, 5.00). After stratification, transience and sexual vulnerability remained significantly associated among women but not men. Ensuring that young Aboriginal people have access to safe spaces to live, work, and inject must include policies addressing residential transience as well as the absence of a roof and walls.

Abstract
The aim of this exploratory pilot study was to adapt a psychological intervention to improve adherence to medication for patients with rheumatoid arthritis (RA). The approach draws on cognitive behavioural therapy (CBT) techniques, including motivational interviewing . The current study aimed to (i) adapt the intervention for patients with RA, (ii) assess its effectiveness in improving adherence to medication and (iii) evaluate patients' experience of the intervention. Participants were randomly allocated to either the 'intervention group' (N = 10), receiving up to six weekly sessions of 'Compliance Therapy', or to the 'wait-list control' group (N = 8), who received standard care. Data was collected pre intervention (baseline), post intervention and at six weeks post intervention (follow-up). Eighteen female participants with a mean age of 48.78 years (SD 15.12) took part in the study. Comparisons across the two time points for each group found that only those in the 'intervention' group demonstrated significant improvement in mean scores on adherence measures. Between-group comparisons were not significant. The pilot study suggests that an intervention based on CBT may improve adherence in patients with RA, but further research is required.

Abstract
This study explored trends of sexual assault and associated risk factors within a cohort of young Aboriginal women who used drugs in Vancouver and Prince George, Canada, between 2003 and 2010. Results demonstrated no change in the trend of sexual assault over time; however, odds of sexual assault were significantly higher for women who had at least one parent who attended residential school, had experienced childhood sexual abuse, were involved in sex work, had been offered money to not use condoms, had used injection drugs, had injected cocaine and opiates daily, had binged with injection drugs, and had difficulty accessing clean syringes. Findings highlight the urgency of interventions addressing the complexity of risk and opportunities for healing.

Abstract
Purpose To investigate the clinical and cost effectiveness of switching real-life asthma patients from other types of inhalers to the Easyhaler® (EH) for the administration of inhaled corticosteroids (ICS). Patients and methods Historical, matched-cohort study of 1,958 asthma patients (children and adults) treated in UK primary-care practices, using data obtained from the Optimum Patient Care Research Database and Clinical Practice Research Datalink. Other inhalers (OH) included pressurized metered-dose inhalers, breath-actuated inhalers, and dry-powder inhalers, delivering beclomethasone, budesonide, fluticasone, or ciclesonide. Patients remaining on OH unchanged (same drug, dosage, and device; n=979) were matched 1:1 with those switched to the EH (beclomethasone or budesonide) at the same or lower ICS dosage (n=979), based on age, sex, year of index patient review/switch, most recent ICS drug, dosage, and device, and the number of severe exacerbations and average daily short-acting β2 agonist (SABA) dosage in the preceding year. Clinical outcomes and health care costs were compared between groups for 12 months before and after the switch. Co-primary clinical outcomes were: 1) risk domain asthma control (RDAC) – no asthma-related hospitalization, acute oral steroid use, or lower respiratory tract infection (LRTI); 2) exacerbation rate (American Thoracic Society [ATS] definition) – where exacerbation is asthma-related hospitalization or acute oral steroid use; 3) exacerbation rate (clinical definition) – where exacerbation is ATS exacerbation or LRTI; and 4) overall asthma control (OAC) – RDAC plus average salbutamol-equivalent SABA dosage ≤200 μg/day. Non-inferiority (at least equivalence) of EH was tested against OH for the four co-primary outcomes in order (hierarchical approach) by comparing the difference in proportions of patients [EH-OH] achieving asthma control or having no exacerbations in the outcome year, using a limit of 10% difference. Results Non-inferiority was shown for the EH for all four co-primary outcomes. There were no significant differences between groups for RDAC or exacerbation rates, but EH patients were significantly more likely to achieve OAC (adjusted odds ratio [95% confidence interval]: 1.26 [1.05, 1.52]), as significantly more EH than OH patients had an average SABA dosage of ≤200 μg/day (52% versus 47%, respectively; P<0.001). Mean asthma-related health care costs increased from baseline to outcome years in both groups, but SABA costs increased significantly more in OH than EH patients (mean difference £5.5/patient/year) and consultation costs decreased significantly more in EH than OH patients (mean difference £13.5/patient/year). Conclusion Typical asthma patients may be switched from other ICS devices to the Easyhaler® with no reduction in clinical effectiveness or increase in cost.

Abstract
BACKGROUND Prion contamination is a risk during device reprocessing, being difficult to remove and inactivate. Little is known of the combined effects of cleaning, disinfection and sterilization during a typical reprocessing cycle in clinical practice. AIM To investigate the combination of cleaning, disinfection and/or sterilization on reducing the risk of surface prion contamination. METHODS In vivo test methods were used to study the impact of cleaning alone and cleaning combined with thermal disinfection and high- or low-temperature sterilization processes. A standardized test method, based on contamination of stainless steel wires with high titres of scrapie-infected brain homogenates, was used to determine infectivity reduction. FINDINGS Traditional chemical methods of surface decontamination against prions were confirmed to be effective, but extended steam sterilization was more variable. Steam sterilization alone reduced the risk of prion contamination under normal or extended exposure conditions, but did show significant variation. Thermal disinfection had no impact in these studies. Cleaning with certain defined formulations in combination with steam sterilization can be an effective prion decontamination process, in particular with alkaline formulations. Low-temperature, gaseous hydrogen peroxide sterilization was also confirmed to reduce infectivity in the presence and absence of cleaning. CONCLUSION Prion decontamination is affected by the full reprocessing cycle used on contaminated surfaces. The correct use of defined cleaning, disinfection and sterilization methods as tested in this report in the scrapie infectivity assay can provide a standard precaution against prion contamination.

Abstract
Antimicrobial resistance is a concern both for animal and human health. Veterinary programmes monitoring resistance of animal and zoonotic pathogens are therefore essential. Various European countries have implemented national surveillance programmes, particularly for zoonotic and commensal bacteria, and the European Food Safety Authority (EFSA) is compiling the data. However, harmonisation is identified as a weakness and an essential need in order to compare data across countries. Comparisons of resistance monitoring data among national programmes are hampered by differences between programmes, such as sampling and testing methodology, and different epidemiological cut-off values or clinical breakpoints. Moreover, only very few valid data are available regarding target pathogens both of farm and companion animals. The European Animal Health Study Centre (CEESA) attempts to fill these gaps. The resistance monitoring programmes of CEESA have been a collaboration of veterinary pharmaceutical companies for over a decade and include two different projects: the European Antimicrobial Susceptibility Surveillance in Animals (EASSA) programme, which collects food-borne bacteria at slaughter from healthy animals, and the pathogen programmes that collect first-intention target pathogens from acutely diseased animals. The latter comprises three subprogrammes: VetPath; MycoPath; and ComPath. All CEESA projects include uniform sample collection and bacterial identification to species level in various European Union (EU) member states. A central laboratory conducts quantitative susceptibility testing to antimicrobial agents either important in human medicine or commonly used in veterinary medicine. This 'methodology harmonisation' allows easy comparisons among EU member states and makes the CEESA programmes invaluable to address food safety and antibiotic efficacy.

Abstract
With increasing numbers of orthopaedic devices being implanted, greater emphasis is being placed on ceramic coating technology to reduce friction and wear in mating total joint replacement components, in order to improve implant function and increase device lifespan. In this chapter, we consider ultra-hard carbon coatings, with emphasis on nanostructured diamond, as alternative bearing surfaces for metallic components. Such coatings have great potential for use in biomedical implants as a result of their extreme hardness, wear resistance, low friction and biocompatibility. These ultra-hard carbon coatings can be deposited by several techniques resulting in a wide variety of structures and properties.

Abstract
The ras family of oncogenes are the most frequently activated group of dominant transforming genes in both human and experimental cancers. The ras family of genes encode highly similar proteins with molecular weights of 21 kDa which are thought to play a key role in signal transduction. Activation in vivo by point mutations results in the ras p21 protein being maintained in the activated form and stimulating cellular proliferation autonomously. Point mutations at codon 12 of K-ras have been observed in >75% of cases of adenocarcinomas of the exocrine pancreas. The type and frequency of K-ras gene mutations in pancreatic cancer cell lines and in bile samples from patients with cytologically-proven biliary tract malignancies and from patients with non-malignant disorders of the biliary tract were determined. Codons 12, 13 and 61 of the K-ras gene were analysed by using restriction fragment length polymorphisms created through mismatched primers during polymerase chain reaction (PCR) of genomic DNA. A mutation of codon 12 of K-ras was detected in 10 of 13 (77%) human pancreatic cancer cell lines. The amino-acid substitutions were glycine to aspartate (5 samples), arginine (2), valine (2) and cysteine (1). No mutations were found at codons 13 or 61. A mutation at codon 12 of K-ras was detected in 9 of 18 (50%) of bile samples analysed. Eleven bile samples had positive cytology for malignancy of pancreaticobiliary origin, and 4 (36%) of these had a codon 12 mutation. Mutations were detected in 5 of the 7 (71%) cytologically-negative bile samples, although malignancy was subsequently diagnosed in 2 of these patients on further histology, and was suspected in 3 other cases on clinical and radiological criteria. This method provides a rapid determination of K-ras gene mutations in bile samples for patients with pancreatic and biliary tract diseases, which may be useful when considering future therapy directed at inhibition of activated ras-induced signal transduction pathways.

Abstract
Mucoepidermoid carcinoma is the most common primary malignancy of the salivary glands. Central mucoepidermoid carcinomas are extremely rare in the jaws. Here we report a case of a 19-year-old central mucoepidermoid carcinoma in a young female patient which was asymptomatic throughout her history and which radiographically simulated a fibro-osseous lesion; both features misled the clinical diagnosis. A radiographic picture of mixed radiopaque-radiolucent appearance in central mucoepidermoid carcinoma is extremely rare. The long duration is also uncommon for a malignant lesion. This case report adds a new dimension to the clinical and radiographic picture a central mucoepidermoid carcinoma can reveal.

Abstract
A biofilm can be defined as a community of microorganisms adhering to a surface and surrounded by a complex matrix of extrapolymeric substances. It is now generally accepted that the biofilm growth mode induces microbial resistance to disinfection that can lead to substantial economic and health concerns. Although the precise origin of such resistance remains unclear, different studies have shown that it is a multifactorial process involving the spatial organization of the biofilm. This review will discuss the mechanisms identified as playing a role in biofilm resistance to disinfectants, as well as novel anti-biofilm strategies that have recently been explored.
