Abstract
BACKGROUND During the COVID-19 pandemic, healthcare systems and healthcare workers (HCWs) faced significant demands and unique challenges. In this qualitative study, we explore the effects of the COVID-19 public health policies on British Columbia's frontline HCWs, describe what worked in the management of the pandemic, and elucidate the lessons learned that could be applied to future pandemic preparedness, recovery and response. METHODS This qualitative descriptive study is part of a larger, national multi-case study on pandemic policy communication and uptake. Semi-structured interviews were conducted from November 2020- June 2021 with fourteen HCWs working in long-term care (LTC), acute care and public health settings. Data were inductively coded, and analyzed following a resilience framework for public health emergency preparedness, which emphasizes the essential elements of a public health system, vital to all phases of health emergency management, readiness, response and recovery. RESULTS HCWs experienced confusion, frustration, uncertainty, anxiety, fatigue and stress, during the pandemic and detailed challenges that affected policy implementation. This included communication and coordination inconsistencies between the province and regional health authorities; lack of involvement of frontline staff in pandemic planning; inadequate training and support; inadequate personal protective equipment resource capacity and mobilization; and staffing shortages. HCWs recommended increased collaboration between frontline staff and policy makers, investment in preparing and practicing pandemic plans, and the need for training in emergency management and infection prevention and control. CONCLUSIONS Pandemic planning, response and recovery should include inputs from actors/key stakeholders at the provincial, regional and local levels, to facilitate better coordination, communication and outcomes. Also, given the critical roles of frontline HCWs in policy implementation, they should be adequately supported and consideration must be given to how they interpret and act on policies. Bi-directional communication channels should be incorporated between policymakers and frontline HCWs to verify the appropriate adoption of policies, reflective learning, and to ensure policy limitations are being communicated and acted upon by policy makers.

Abstract
BACKGROUND Symptomatic knee osteoarthritis (OA) commonly co-occurs in people with type 2 diabetes (T2DM) and increases the risk for diabetes complications, yet uptake of evidence-based treatment is low. We combined theory, stakeholder involvement and existing evidence to develop a multifaceted intervention to improve OA care in persons with T2DM. This was done in partnership with Arthritis Society Canada to leverage the existing infrastructure and provincial funding for community arthritis care. METHODS Each step was informed by a User Advisory Panel of stakeholder representatives, including persons with lived experience. First, we identified the target groups and behaviours through consulting stakeholders and current literature. Second, we interviewed persons living with T2DM and knee OA (n = 18), health professionals (HPs) who treat people with T2DM (n = 18) and arthritis therapists (ATs, n = 18) to identify the determinants of seeking and engaging in OA care (patients), assessing and treating OA (HPs) and considering T2DM in OA treatment (ATs), using the Theoretical Domains Framework (TDF). We mapped the content to behavioural change techniques (BCTs) to identify the potential intervention components. Third, we conducted stakeholder meetings to ascertain the acceptability and feasibility of intervention components, including content and modes of delivery. Fourth, we selected intervention components informed by prior steps and constructed a programme theory to inform the implementation of the intervention and its evaluation. RESULTS We identified the barriers and enablers to target behaviours across a number of TDF domains. All stakeholders identified insufficient access to resources to support OA care in people with T2DM. Core intervention components, incorporating a range of BCTs at the patient, HP and AT level, sought to identify persons with knee OA within T2DM care and refer to Arthritis Society Canada for delivery of evidence-based longitudinal OA management. Diverse stakeholder input throughout development allowed the co-creation of an intervention that appears feasible and acceptable to target users. CONCLUSIONS We integrated theory, evidence and stakeholder involvement to develop a multifaceted intervention to increase the identification of knee OA in persons with T2DM within diabetes care and improve the uptake and engagement in evidence-based OA management. Our partnership with Arthritis Society Canada supports future spread, scalability and sustainability. We will formally assess the intervention feasibility in a randomized pilot trial.

Abstract
BACKGROUND People experiencing homelessness are vulnerable to SARS-CoV-2 infection and its consequences. We aimed to understand the perspectives of people experiencing homelessness, and of the health care and shelter workers who cared for them, during the COVID-19 pandemic. METHODS We conducted an interpretivist qualitative study in Toronto, Canada, from December 2020 to June 2021. Participants were people experiencing homelessness who received SARS-CoV-2 testing, health care workers and homeless shelter staff. We recruited participants via email, telephone or recruitment flyers. Using individual interviews conducted via telephone or video call, we explored the experiences of people who were homeless during the pandemic, their interaction with shelter and health care settings, and related system challenges. We analyzed the data using reflexive thematic analysis. RESULTS Among 26 participants were 11 men experiencing homelessness (aged 28-68 yr), 9 health care workers (aged 33-59 yr), 4 health care leaders (aged 37-60 yr) and 2 shelter managers (aged 47-57 yr). We generated 3 main themes: navigating the unknown, wherein participants grappled with evolving public health guidelines that did not adequately account for homeless individuals; confronting placelessness, as people experiencing homelessness often had nowhere to go owing to public closures and lack of isolation options; and struggling with powerlessness, since people experiencing homelessness lacked agency in their placelessness, and health care and shelter workers lacked control in the care they could provide. INTERPRETATION Reduced shelter capacity, public closures and lack of isolation options during the COVID-19 pandemic exacerbated the displacement of people experiencing homelessness and led to moral distress among providers. Planning for future pandemics must account for the unique needs of those experiencing homelessness.

Abstract
Aim We plan to conduct a randomised clinical trial among people likely to witness opioid overdose to compare the educational effectiveness of point-of-care naloxone distribution with best-available care, by observing participants’ resuscitation skills in a simulated overdose. This mixed methods feasibility study aims to assess the effectiveness of recruitment and retention strategies and acceptability of study procedures. Methods We implemented candidate-driven recruitment strategies with verbal consent and destigmatizing study materials in a family practice, emergency department, and addictions service. People ≥16 years of age who are likely to witness overdose were randomized to point-of-care naloxone distribution or referral to an existing program. We evaluated participant skills as a responder to a simulated overdose 3–14 days post-recruitment. Retention strategies included flexible scheduling, reminders, cash compensation and refreshments. The primary outcome was recruitment and retention feasibility, defined as the ability to recruit 28 eligible participants in 28 days, with <50% attrition at the outcome simulation. Acceptability of study procedures and motivations for participation were assessed in a semi-structured interview. Results We enrolled 30 participants over 24 days, and retained 21 participants (70%, 95%CI 56.7–100). The most common motivation for participation was a desire to serve the community or loved ones in distress. Participants reported that study procedures were acceptable and that the outcome simulation provided a supportive and affirming environment. Conclusion The planned trial is ready for implementation. Recruitment and retention is feasible and study processes are acceptable for people who are likely to witness overdose. (Registration: NCT03821649).

Abstract
Abstract
Introduction
Radiotherapy for locally advanced rectal cancer is conventionally performed using photon-based radiotherapy (PBR), carrying significant risk of toxicity to organs at risk (OAR). Proton beam therapy (PBT) potentially delivers equivalent dosimetric radiation to the targeted tissue with improved sparing of OAR. We aimed to compare dosimetric irradiation of OAR for PBT versus PBR in patients with rectal cancer and assess any oncological outcomes.
Method
An extensive electronic literature search was performed from inception till April 2020 and subsequent meta-analysis performed.
Results
Six articles met the inclusion criteria. Dosimetric data of irradiation delivered to OAR for PBT and PBR were calculated for the same patients. PBT had significantly less irradiated small bowel compared to 3DCRT and IMRT, (MD -16.95, 95% CI [-24.03, -9.88], p < 0.00001) and (MD -6.96, 95% CI [-12.99, -0.94], p = 0.02) respectively. Similar results were observed for bladder and pelvic bone marrow. Two studies reported clinical and oncological results for PBT in recurrent rectal cancer with overall survival reported as 43% and 68%.
Conclusions
Dosimetric treatment plans have less irradiation of OAR for rectal cancer with PBT compared to PBR. There is a need for further research in PBT and rectal cancer, as promising results have been shown in recurrent rectal cancer.

Abstract
Abstract
Introduction
Our proteomic data has validated that high levels of the protein myoferlin confers poorer response to neoadjuvant chemoradiotherapy in locally advanced rectal cancer. Myoferlin plays a role in membrane repair and VEGF signal transduction, and is associated with worse prognosis in numerous other epithelial cancers. We aim to assess the impact of myoferlin on the radiosensitivity of rectal cancer.
Method
Clonogenic assays were performed using immortalised colorectal cancer cells (HCT116,HT29,LIM,MDST8) to assess survival at escalating radiation doses following knockdown with myoferlin siRNA or a small molecular inhibitor(WJ460). 3D models (spheroids) were used to examine the effect of WJ460 on tumour growth.
Result
Quantification of myoferlin using immunoblotting demonstrated that MDST8 and LIM were higher expressors than HCT116 and HT29. Higher levels correlated with increasing radio-resistance as calculated by colony formation efficiency (CFE). Using clonogenic assays, cells treated with myoferlin siRNA or WJ460 demonstrated increased radiosensitivity compared to controls across all radiation doses, most significantly at 4Gy. Treatment of spheroids with WJ460 significantly reduced growth compared to controls at all radiation doses (p<0.05), with WJ460 limiting growth considerably more than treatment with the current gold standard 5-FU. HCT116 spheroid volume day 15; WJ460 4.96um3,5-FU 6.74um3,DMSO 24.9um3.
Conclusion
Inhibition of myoferlin is associated with increased radiosensitivity of colorectal cancer cells, and treatment with a small molecular inhibitor significantly reduces growth in spheroid models. Further work is required further validate its potential use as a biomarker in locally advanced rectal cancer.
Take-home message
We have found that myoferlin is a protein associated with poor response to neoadjuvant chemoradiotherapy in locally advanced rectal cancer. Manipulation of this protein sensitises the cancer cells to radiotherapy.

Abstract
Abstract
Introduction
Myoferlin is a protein involved in cell proliferation, migration and angiogenesis, which are essential in tumour metastasis. Its expression correlates with a poorer prognosis in various epithelial cancers, but has yet to be associated with survival in colorectal cancer. We aim to investigate myoferlin's role in cell migration, and the development of metastases in our patients with rectal cancer.
Method
Tissue Microarrays (TMAs) of matched tumour and lymph node samples from 111 patients with rectal cancer were stained for myoferlin. Expression profiles were examined and correlated with clinical outcomes. Wound healing assays were used to assess the rate of migration in immortalised colorectal cells (HCT116, HT29) following myoferlin knockdown with siRNA.
Result
Our TMAs demonstrated that high myoferlin expression in rectal tumour samples was associated with metastatic spread to local lymph nodes (p<0.05). Positive lymph nodes had significantly higher levels of myoferlin than non-involved lymph nodes (p<0.001). The positive predictive value (PPV) of a highly expressing lymph node containing metastatic spread was 100%, negative predictive value (NPV) 88.41%, 95% CI [80.81, 93.24]. Wound healing assays demonstrated a decreased ability of cells to migrate following myoferlin knockdown with siRNA, compared to controls (p<0.05).
Conclusion
Our results demonstrate that high myoferlin expression is associated with metastatic spread to local lymph nodes, and increased migration and proliferation of cells. It is a predictor of poor clinical outcomes, and therefore warrants further investigation as a potential therapeutic target in both locally advanced and metastatic rectal cancer.
Take-home message
We have demonstrated that the protein myoferlin is associated with metastatic spread of rectal cancer to local lymph nodes. Therefore it is a potential predictive biomarker and therapeutic target in advanced rectal cancer.

Abstract
Recently Boreskie and colleagues published an editorial in the Journal of Frailty and Aging on Preventing Frailty Progression During the COVID-19 Pandemic (1). In it they proposed the SAVE programme (Socialization, Adequate nutrition, Vitamin D, Exercise) to prevent frailty. They concluded that creative thinking and concerted efforts would be needed to disseminate health recommendations to maintain the health of pre-frail and frail older adults in unprecedented times, such as those posed by the COVID-19 pandemic.

Abstract
BACKGROUND Studies examining gender-based differences in outcomes of patients experiencing out-of-hospital cardiac arrest have demonstrated that, despite a higher likelihood of return of spontaneous circulation, women do not have higher survival. METHODS Patients successfully resuscitated from out-of-hospital cardiac arrest enrolled in the CCC trial (Trial of Continuous or Interrupted Chest Compressions during CPR) were included. Hierarchical multivariable logistic regression models were constructed to evaluate the association between gender and survival after adjustment for age, gender, cardiac arrest rhythm, witnessed status, bystander cardiopulmonary resuscitation, episode location, epinephrine dose, emergency medical services response time, and duration of resuscitation. Do not resuscitate (DNR) and withdrawal of life-sustaining therapy (WLST) order status were used to assess whether differences in postresuscitation outcomes were modified by baseline prognosis. The analysis was replicated among ALPS trial (Amiodarone, Lidocaine, or Placebo in Out-of-Hospital Cardiac Arrest) participants. RESULTS Among 4875 successfully resuscitated patients, 1825 (37.4%) were women and 3050 (62.6%) were men. Women were older (67.5 versus 65.3 years), received less bystander cardiopulmonary resuscitation (49.1% versus 54.9%), and had a lower proportion of cardiac arrests that were witnessed (55.1% versus 64.5%) or had shockable rhythm (24.3% versus 44.6%, P<0.001 for all). A significantly higher proportion of women received DNR orders (35.7% versus 32.1%, P=0.009) and had WLST (32.8% versus 29.8%, P=0.03). Discharge survival was significantly lower in women (22.5% versus 36.3%, P<0.001; adjusted odds ratio, 0.78 [95% CI, 0.66-0.93]; P=0.005). The association between gender and survival to discharge was modified by DNR and WLST order status such that women had significantly reduced survival to discharge among patients who were not designated DNR (31.3% versus 49.9%, P=0.005; adjusted odds ratio, 0.74 [95% CI, 0.60-0.91]) or did not have WLST (32.3% versus 50.7%, P=0.002; adjusted odds ratio, 0.73 [95% CI, 0.60-0.89]). In contrast, no gender difference in survival was noted among patients receiving a DNR order (6.7% versus 7.4%, P=0.90) or had WLST (2.8% versus 2.4%, P=0.93). Consistent patterns of association between gender and postresuscitation outcomes were observed in the secondary cohort. CONCLUSIONS Among patients resuscitated after experiencing out-of-hospital cardiac arrest, discharge survival was significantly lower in women than in men, especially among patients considered to have a favorable prognosis.

Abstract
Abstract
Introduction
Sleep study volume in our system has increased by 23% from 2017 to 2019 which makes unfilled sleep beds a significant concern. Cancellation rate impacts our sleep bed access. We hypothesized cancellation can be improved through quality improvement process which could ultimately lead to improve patient satisfaction.
Methods
A multi-disciplinary team was assembled to examine potential contributing factors. Using the Model for Improvement we developed, tested and implemented interventions using tools such as PDSA cycles, process map and a simplified FMEA (Failure Modes and Effects Analysis). A Key Driver Diagram helped guide our journey to improve the cancellation rate. We developed a Parent Advisory Group to help us with ideas to identify how we could improve the cancellation rate.
Results
The cancellation was 21% prior to the implementation of our interventions. To improve these measures, we have implemented several interventions. The content of our sleep study preparation handbook was improved, increased distribution of the education handbook and developed a series of sleep study videos which are available for viewing prior to the study to prepare patients and families. In addition, we standardized our process of reminder calls in the call center and sleep lab by defining roles and responsibilities. This improved our ability to answer questions and identify and mitigate barriers they may have. We implemented transportation assistance to patients who have transportation barriers and created a waitlist protocol to assist families with a preferred date. After 2 years of interventions, the cancellation rate has decreased from 21% to 14.7%. Interestingly, as we improved our cancellation rate, the overall patient satisfaction has been improved from 83% to 88%.
Conclusion
Using the Model for Improvement, we improved education, communication and scheduling processes, which has reduced cancellation rate and consequently improved patient satisfaction.

Abstract
BACKGROUND Patients with cancer who are treated with immune checkpoint modulators (ICMs) have their health-related quality of life (HRQOL) measured using general patient-reported outcome (PRO) tools. To the authors' knowledge, no instrument has been developed to date specifically for patients treated with ICMs. The objective of the current study was to develop a toxicity subscale PRO instrument for patients treated with ICMs to assess HRQOL. METHODS Input was collected from a systematic review as well as patients and physicians experienced with ICM treatment. Descriptive thematic analysis was used to evaluate the qualitative data obtained from patient focus groups and interviews, which informed an initial list of items that described ICM side effects and their impact on HRQOL. These inputs informed item generation and/or reduction to develop a toxicity subscale. RESULTS Focus groups and individual interviews with 37 ICM-treated patients generated an initial list of 176 items. After a first round of item reduction that produced a shortened list of 76 items, 16 physicians who care for patients who are treated with ICMs were surveyed with a list of 49 patient-reported side effects and 11 physicians participated in follow-up interviews. A second round of item reduction was informed by the physician responses to produce a list of 25 items. CONCLUSIONS To the authors' knowledge, this 25-item list is the first HRQOL-focused toxicity subscale for patients treated with ICMs and was developed in accordance with US Food and Drug Administration guidelines, which prioritize patient input in developing PRO tools. The subscale will be combined with the Functional Assessment of Cancer Therapy-General (FACT-G) to form the FACT-ICM. Prior to recommending the formal use of this PRO instrument, the authors will evaluate its validity and reliability in longitudinal studies involving substantially more patients.

Abstract
BACKGROUND When young adults transfer from pediatric to adult diabetes care they are at risk for deterioration of glycemic control, putting them at an increased risk of developing both acute and chronic complications. Despite increased awareness of these risks, there are gaps in care delivery during this vulnerable time and variability in the implementation of recommended transition practice. Audit and feedback (AF) interventions have a positive but variable effect on implementation of best practices. An expert group identified specific suggestions for optimizing the effectiveness of AF interventions. We aim to test an AF-based intervention incorporating these specific suggestions to improve transition practices and glycemic control in the first year after transfer from pediatric to adult diabetes care. METHODS This is a pragmatic quasi-experimental study; a series of three cohort studies (pre-implementation, early-implementation, and post-implementation) to compare the baseline adjusted hemoglobin A1c (HbA1c) in the 12 months after the final pediatric visit in five pediatric diabetes centres within the Ontario Pediatric Diabetes Network in Ontario, Canada. The intervention includes three components: 1) centre-level feedback reports compiling data from chart abstraction, linked provincial administrative datasets, and patient-reported experience measures; 2) webinars for facilitated conversations/coaching about the feedback; and 3) online repository of curated transition resources for providers. The primary outcome will be analyzed using a multivariable linear regression model. We will conduct a qualitative process evaluation to understand intervention fidelity and to provide insight into the mechanisms of action of our results. DISCUSSION There is a need to develop an innovative system-level approach to improve outcomes and the quality of care for young adults with type 1 diabetes during the vulnerable time when they transfer to adult care. Our research team, a collaboration of health services, implementation science, and quality improvement researchers, are designing, implementing, and evaluating an AF-based intervention using recommendations about how to optimize effectiveness. This knowledge will be generalizable to other care networks that aim to deliver uniformly high-quality care in diverse care settings. TRIAL REGISTRATION ClinicalTrials.gov NCT03781973.

Abstract
Within mainstream cancer literature, policy documents, and clinical practice, "work" is typically characterized as being synonymous with paid employment, and the problem of work is situated within the "return to work" discourse. The work that patients perform in managing their health, care, and everyday life at times of illness, however, is largely overlooked and unsupported. Drawing on feminist political economy theory, we report on a qualitative study of 12 women living with cancer. Major findings show that the work of patienthood cut across multiple fields of practice and included both paid and unpaid labor. The most prevalent types of work included illness work, body work, identity work, everyday work, paid employment and/or the work of maintaining income, and coordination work. The findings of this study disrupt popular conceptualizations of work and illuminate the nuanced and often invisible work that cancer patients may encounter, and the health consequences and inequities therein.

Abstract
AIM To inform targeted interventions for women with gestational diabetes mellitus (GDM) by exploring the factors that influence their health behaviours and their preferences for lifestyle support. METHODS Participants were women with previous GDM taken from a diverse inner-city UK population. Data collection involved focus groups (n = 35 women in six groups) and semi-structured interviews (n = 15 women). The transcribed data were analysed using framework analysis. RESULTS Eight themes relating to factors influencing health behaviour were identified: psychological legacy of pregnancy, relationships with healthcare professionals, physical impacts of pregnancy, social support and cultural norms, life-scheduling, understanding and risk perception, appetite regulation, and prioritization of the baby. The women's recommendations for intervention components included addressing the emotional stress of pregnancy; conveying personalized risk in a motivational way, adopting a family-centered approach, focusing on women's health rather than just the infant's, and developing flexible interventions. These recommendations were used to construct a model integrating the behaviour-regulating factors with a suggested framework for intervention. CONCLUSIONS This study identified some common drivers that may regulate the health behaviours of women following GDM, and recognized some ways to improve care to impact on this. Interventions for diabetes prevention in this population need to address factors at both the individual and systemic levels.

Abstract
BACKGROUND Maternal obesity is a risk factor for adverse maternal, fetal, and neonatal events. Numerous clinical trials are currently exploring the effectiveness of antenatal and peripartum interventions in improving pregnancy outcomes that can in future inform clinical practice. However, the heterogeneity in outcome reporting limits our ability to compare outcomes across studies, and there is a lack of stakeholder representation in outcome choice. A pragmatic solution to this problem is the development of a core outcome set (COS) that defines the minimum criteria for outcome reporting in clinical trials undertaken in this population, arrived at by the involvement of relevant stakeholders. METHODS The development of a COS for studies on obesity in pregnant patients (COSSOPP) will comprise five steps. First, a systematic review of published literature will identify the long list of outcomes, their definitions and measurements if applicable, and outcome reporting quality. This will be followed by a meta-synthesis of qualitative studies with patients, and qualitative interviews in Toronto with patients, clinicians, researchers, hospital administrators, and policy-makers, to identify novel outcomes that were not obtained through systematic review. Third, the long list of outcomes will be narrowed down through online Delphi surveys involving an international group of patients and relevant stakeholders. This will be followed by a face-to-face consensus meeting with representatives of all stakeholder groups to arrive at a consensus on the final COS. Finally, in order to determine how the identified core outcomes should be measured, we will conduct another literature review and Delphi process. DISCUSSION COSSOPP will engage patients, clinicians, researchers, and other relevant stakeholders in determining the core set of outcomes that should be reported and measured in order to harmonize outcome reporting in studies evaluating the effectiveness of antepartum and peripartum interventions in obese pregnant women. This protocol provides a detailed overview of the steps involved in the development of a COS, to guide researchers in developing COS within their areas of specialization.

Abstract
The objective of this 2-yr study was to evaluate growing and finishing performance as well as carcass characteristics of spring-born steers backgrounded on 3 different systems, using feedstuffs readily available in the Midwest: 1) grazing corn residue and being supplemented with dried distillers plus solubles at 2.68 kg DM/steer 6 d/wk (RESIDUE), 2) grazing a late summer-planted oat-brassica forage mix (CCROP), or 3) being fed a corn silage-based diet in a drylot (DRYLOT). Steers ( = 715) were stratified by BW (278 kg ± 23 in yr 1 and 291 kg ± 91 in yr 2) and assigned to treatment and replicate (4 replications per treatment per yr). Steers assigned to DRYLOT were fed a corn silage-based diet for 54 d in yr 1 and 52 d in yr 2 before being transitioned to the finishing diet. Steers assigned to RESIDUE and those assigned to CCROP grazed 65 d in yr 1 and 66 d in yr 2 and then were fed a corn silage-based diet for 21 d in yr 1 and 33 d in yr 2 before being transitioned to the finishing diet. During backgrounding, the ADG (SEM 0.022) of steers assigned to DRYLOT (1.48 kg/d) was greater ( < 0.01) than that of steers assigned to both CCROP (1.05 kg/d) and RESIDUE (0.87 kg/d) and ADG of steers assigned to CCROP was greater ( < 0.01) than that of steers assigned to RESIDUE. At the start of the finishing period, BW of steers assigned to CCROP (381 kg) was greater ( < 0.01, SEM 2.5) than that of steers assigned to DRYLOT (361 kg) and RESIDUE (366 kg). The finishing period lasted 160 d for all treatments. Both 12th-rib fat ( = 0.89) and calculated yield grade ( = 0.39) did not differ among treatments. Finishing G:F of steers assigned to DRYLOT (0.162 kg/kg) was greater ( < 0.01, SEM 0.0015) than that of steers assigned to RESIDUE (0.153 kg/kg) and CCROP (0.153 kg/kg), which did not differ ( = 0.79). In yr 1, HCW of steers assigned to CCROP (402 kg) was greater ( < 0.01, SEM 2.1) than that of steers assigned to both RESIDUE (389 kg) and DRYLOT (391 kg), which did not differ ( = 0.40). This difference in HCW is most likely a result of differences in BW at the start of the finishing phase in yr 1. However in yr 2, HCW of steers assigned to CCROP (400 kg) and RESIDUE (397 kg) did not differ ( = 0.26, SEM 2.1) but were greater ( < 0.01) than that of steers assigned to DRYLOT (367 kg), despite the fact that steers assigned to RESIDUE entered the finishing phase at a lighter BW than steers assigned to CCROP. Marbling was greater ( = 0.01, SEM 3.9) for steers assigned to DRYLOT (429) than for steers assigned to RESIDUE (414), although steers assigned to CCROP (424) were not different ( ≥ 0.10) from steers assigned to DRYLOT or RESIDUE. When cost and price scenarios from the last 5 yr were conducted, no treatment appeared to be consistently superior in terms of cost of gain or net return. Therefore, all 3 systems appear to be viable options for producers.

Abstract
This paper focuses on accounts of how having a disability and being HIV-positive influences experiences of work among 21 people (12 women, 9 men) in Lusaka, Zambia. In-depth semi-structured interviews were conducted in English, Bemba, Nyanja, or Zambian sign language. Descriptive and thematic analyses were conducted. Three major themes were generated. The first, a triple burden, describes the burden of having a disability, being HIV-positive, and being unemployed. The second theme, disability and HIV is not inability, describes participants' desire for work and their resistance to being regarded as objects of charity. Finally, how work influences HIV management, describes the practicalities of working and living with HIV. Together these themes highlight the limited options available to persons with disabilities with HIV in Lusaka, not only secondary to the effects of HIV influencing their physical capacity to work, but also because of the attendant social stigma of being a person with a disability and HIV-positive.

Abstract
PURPOSE To determine the effect of Vibration Training (VT) on functional ability and falls risk among a group of frail older people admitted to an inpatient rehabilitation unit in a regional hospital in New Zealand. METHOD A randomized controlled trial of 56 participants (mean 82.01 years in the intervention group and 81.76 years in the control group). VT targeting lower limb muscles with a frequency 30-50 Hz occurred three times per week until discharge. Amplitude progressively increased from 2 to 5 mm to allow the programme to be individually tailored to the participant. The control group received usual care physiotherapy sessions. Outcome measures were: Physiological profile assessment (PPA); and Functional Independence measure (FIM) and Modified Falls Efficacy Scale (MFES). RESULTS There was a statistically significant difference observed between the two groups in terms of FIM score (F = 5.09, p = 0.03) and MFES (F = 3.52, p = 0.007) but no difference was observed in terms of PPA scores (F = 0.96, p = 0.36). CONCLUSIONS Among older people admitted to an inpatient rehabilitation facility there may be some beneficial effect to the use of VT in conjunction with usual care physiotherapy in terms of improved functional ability. The study design and the small dosage of VT provided may have precluded any change in falls risk among participants. IMPLICATIONS FOR REHABILITATION Vibration training (VT) may assist in reducing the risk of falling among at risk older people. Current pressures on health systems (ageing population, reduced hospital length of stay) necessitate the development of innovative strategies to maximise the rehabilitation potential of older people. Among older people admitted to an inpatient rehabilitation facility there may be some beneficial effect to the use of vibration training in conjunction with usual care physiotherapy in terms of improved functional ability.

Abstract
OBJECTIVE We investigated the relationship between a body mass index and tooth wear in the black flying-fox (Pteropus alecto Gould) to provide guidance on management of edentulous individuals by wildlife carers and veterinarians. METHODS Flying-foxes brought into care because of injury were weighed, their forearms measured and the state of their teeth evaluated. Measurements were analysed by Chi-square, ANOVA, t-tests and regression to identify any relationship between the body mass index and the condition of canine and molar teeth, as well as in relation to sex and season. RESULTS There was no statistically significant relationship between a bat's dentition state and the body mass index being used. CONCLUSIONS In Townsville, the black flying-fox appears to experience a rapid decline in dental condition over time. Despite this, there is little indication that loss of teeth results in a decline in body condition. We attribute this to the dominance of floral foods in the bats' diet in Townsville and a lesser importance of hard fruit that requires intact dentition for consumption. Edentulousness on its own is not sufficient reason to euthanase black flying-foxes in either Townsville or similar relatively dry localities where blossom dominates the flying-fox diet.

Abstract
Arts-informed approaches are increasingly popular as vehicles for research, knowledge translation and for engaging key stakeholders on topics of health and health care. This paper describes an evaluation of a multimedia art installation intended to promote awareness of health disparities as experienced by homeless persons living in Toronto (Canada). The objective of the evaluation was to determine whether the installation had an impact on audience members, and if so, to understand its influence on viewers' perspectives on homelessness and the health concerns of homeless persons. Key themes were identified through the analysis of direct observational data of viewer interactions with the exhibit and qualitative interviews with different audience members after the exhibit. The four key themes were: (1) Promoting recognition of common humanity between viewers and viewed (challenging previously held assumptions and stereotypes, narrowing perceived social distance); (2) functions fulfilled (or potentially fulfilled) by the exhibit: raising awareness, educational applications, and potential pathways by which the exhibit could serve as a call to social action; (3) stories that prompt more stories: the stories within the exhibit (coupled with the interview questions) prompted further sharing of stories amongst the evaluation respondents, highlighting the iterative nature of such approaches. Respondents told of recognizing similarities in the experiences recounted in the exhibit with their own interactions with homeless persons; (4) strengths and weaknesses identified: including aesthetic features, issues of audience 'reach' and the importance of suitable venues for exhibition. Theoretically informed by narrative analysis and visual anthropology, this evaluation demonstrates that arts-informed 'interventions' are highly complex and work in subtle ways on viewers, allowing them to re-imagine the lives of others and identify points of common interest. It also problematizes our assumptions about which outcomes matter and why.

Abstract
Background There is ample evidence that residential neighbourhoods can influence mental well-being (MWB), with most studies relying on census or similar data to characterize communities. Few studies have actively investigated local residents’ perceptions. Methods Concept mapping was conducted with residents from five Toronto neighbourhoods representing low income and non-low income socio-economic groups. These residents participated in small groups and attended two sessions per neighbourhood. The first session (brainstorming) generated neighbourhood characteristics that residents felt influenced their MWB. A few weeks later, participants returned to sort these neighbourhood characteristics and rate their relative importance in affecting residents’ ‘good’ and ‘poor’ MWB. The data from the sorting and rating groups were analyzed to generate conceptual maps of neighbourhood characteristics that influence MWB. Results While agreement existed on factors influencing poor MWB (regardless of neighbourhood, income, gender and age), perceptions related to factors affecting good MWB were more varied. For example, women were more likely to rank physical beauty of their neighbourhood and range of services available as more important to good MWB, while men were more likely to cite free access to computers/internet and neighbourhood reputation as important. Low-income residents emphasized aesthetic attributes and public transportation as important to good MWB, while non-low-income residents rated crime, negative neighbourhood environment and social concerns as more important contributors to good MWB. Conclusion These findings contribute to the emerging literature on neighbourhoods and MWB, and inform urban planning in a Canadian context.

Abstract
Background Given that patients provide the majority of their own diabetes care, patient self-management training has increasingly become recognized as an important strategy with which to improve quality of care. However, participation in self management programs is low. In addition, the efficacy of current behavioural interventions wanes over time, reducing the impact of self-management interventions on patient health. Web-based interventions have the potential to bridge the gaps in diabetes care and self-management. Methods Our objective is to improve self-efficacy, quality of life, self-care, blood pressure, cholesterol and glycemic control and promote exercise in people with type 2 diabetes through the rigorous development and use of a web-based patient self-management intervention. This study consists of five phases: (1) intervention development; (2) feasibility testing; (3) usability testing; (4) intervention refinement; and (5) intervention evaluation using mixed methods. We will employ evidence-based strategies and tools, using a theoretical framework of self-efficacy, then elicit user feedback through focus groups and individual user testing sessions. Using iterative redesign the intervention will be refined. Once finalized, the impact of the website on patient self-efficacy, quality of life, self-care, HbA1c, LDL-cholesterol, blood pressure and weight will be assessed through a non-randomized observational cohort study using repeated measures modeling and individual interviews. Discussion Increasing use of the World Wide Web by consumers for health information and ongoing revolutions in social media are strong indicators that users are primed to welcome a new era of technology in health care. However, their full potential is hindered by limited knowledge regarding their effectiveness, poor usability, and high attrition rates. Our development and research agenda aims to address these limitations by improving usability, identifying characteristics associated with website use and attrition, and developing strategies to sustain patient use in order to maximize clinical outcomes.

Abstract
PURPOSE This study evaluated the impact of an educational intervention that integrates concepts of a community re-engagement framework (CR) and interprofessional collaboration (IPC) on health care providers' (HCP) practice with persons living with stroke (PLS). METHOD A mixed-methods design was used in which HCPs (n = 67) and PLS (n = 29) participated from 9 organizations across the care continuum. Pre- and postintervention surveys and interviews were conducted with the HCPs. One-on-one interviews with stroke clients were also conducted pre and post intervention. Quantitative responses were analyzed in SPSS (Chicago, Illinois, USA) for descriptive frequencies and differences between pre- and postintervention groups. Qualitative open-ended responses were thematically coded using NVivo7. RESULTS Significant increases occurred in HCPs' knowledge of CR, confidence levels in working with PLS, enhanced understanding of the complex needs of PLS, and positive self-reported impacts on practice. PLS reported positive perceptions of care pre and post intervention. CONCLUSIONS The intervention provided HCPs with a common language and framework to work collaboratively and holistically in delivering care consistent with stroke best practices.

Abstract
We present a search for pair production of doubly charged Higgs bosons in the processes qq¯→H(++)H(--) decaying through H(±±)→τ(±)τ(±),μ(±)τ(±),μ(±)μ(±). The search is performed in pp¯ collisions at a center-of-mass energy of √s = 1.96 TeV using an integrated luminosity of up to 7.0 fb(-1) collected by the D0 experiment at the Fermilab Tevatron Collider. The results are used to set 95% C.L. limits on the pair production cross section of doubly charged Higgs bosons and on their mass for different H(±±) branching fractions. Models predicting different H(±±) decays are investigated. Assuming B(H(±±)→τ(±)τ(±))=1 yields an observed (expected) lower limit on the mass of a left-handed H(L)(±±) boson of 128 (116) GeV and assuming B(H(±±)→μ(±)τ(±))=1 the corresponding limits are 144 (149) GeV. In a model with B(H(±±)→τ(±)τ(±))=B(H(±±)→μ(±)τ(±))=B(H(±±)→μ(±)μ(±))=1/3, we obtain M(H(L)(±±))>130 (138) GeV.

Abstract
We measure the cross section and the difference in rapidities between photons and charged leptons for inclusive W(→lν) + γ production in eγ and μγ final states. Using data corresponding to an integrated luminosity of 4.2 fb(-1) collected with the D0 detector at the Fermilab Tevatron Collider, the measured cross section times branching fraction for the process pp → Wγ + X → lνγ + X and the distribution of the charge-signed photon-lepton rapidity difference are found to be in agreement with the standard model. These results provide the most stringent limits on anomalous WWγ couplings for data from hadron colliders: -0.4<Δκ(γ)<0.4 and -0.08<λ(γ)<0.07 at the 95% C.L.

Abstract
We present a search for the standard model Higgs boson and a fermiophobic Higgs boson in the diphoton final states based on 8.2 fb(-1) of pp collisions at sqrt[s]=1.96 TeV collected with the D0 detector at the Fermilab Tevatron Collider. No excess of data above background predictions is observed and upper limits at the 95% C.L. on the cross section multiplied by the branching fraction are set which are the most restrictive to date. A fermiophobic Higgs boson with a mass below 112.9 GeV is excluded at the 95% C.L.

Abstract
We report results from a search for neutral Higgs bosons produced in association with b quarks using data recorded by the D0 experiment at the Fermilab Tevatron Collider and corresponding to an integrated luminosity of 7.3 fb(-1). This production mode can be enhanced in several extensions of the standard model (SM) such as in its minimal supersymmetric extension (MSSM) at high tanβ. We search for Higgs bosons decaying to tau pairs with one tau decaying to a muon and neutrinos and the other to hadrons. The data are found to be consistent with SM expectations, and we set upper limits on the cross section times branching ratio in the Higgs boson mass range from 90 to 320 GeV/c(2). We interpret our result in the MSSM parameter space, excluding tanβ values down to 25 for Higgs boson masses below 170 GeV/c(2).

Abstract
We present a measurement of the ratio of top quark branching fractions R=B(t→Wb)/B(t→Wq), where q can be a d, s, or b quark, in the lepton+jets and dilepton tt final states. The measurement uses data from 5.4 fb(-1) of pp collisions collected with the D0 detector at the Fermilab Tevatron Collider. We measure R=0.90±0.04, and we extract the Cabibbo-Kobayashi-Maskawa (CKM) matrix element |V(tb)| as |V(tb)|=0.95±0.02, assuming unitarity of the 3×3 CKM matrix.

Abstract
We present a search for pair production of a fourth generation t' quark and its antiparticle, followed by their decays to a W boson and a jet, based on an integrated luminosity of 5.3 fb(-1) of proton-antiproton collisions at √s = 1.96 TeV collected by the D0 Collaboration at the Fermilab Tevatron Collider. We set upper limits on the t' ̄t' production cross section that exclude at the 95% C.L. a t' quark that decays exclusively to W+jet with a mass below 285 GeV. We observe a small excess in the μ+jets channel which reduces the mass range excluded compared to the expected limit of 320 GeV in the absence of a signal.

Abstract
We measure the top quark mass (m(t)) in p ̄p collisions at a center of mass energy √s = 1.96 TeV using dilepton t ̄t→W(+)bW(-) ̄b→ℓ(+)ν(ℓ)bℓ(-) ̄ν(ℓ) ̄b events, where ℓ denotes an electron, a muon, or a tau that decays leptonically. The data correspond to an integrated luminosity of 5.4 fb(-1) collected with the D0 detector at the Fermilab Tevatron Collider. We obtain m(t)=174.0±1.8(stat)±2.4(syst) GeV, which is in agreement with the current world average m(t)=173.3±1.1 GeV. This is currently the most precise measurement of m(t) in the dilepton channel.
