Abstract
BACKGROUND Promoting the uptake of vaccination for infectious diseases such as COVID-19 remains a global challenge, necessitating collaborative efforts between public health units (PHUs) and communities. Applied behavioural science can play a crucial role in supporting PHUs' response by providing insights into human behaviour and informing tailored strategies to enhance vaccination uptake. Community engagement can help broaden the reach of behavioural science research by involving a more diverse range of populations and ensuring that strategies better represent the needs of specific communities. We developed and applied an approach to conducting community-based behavioural science research with ethnically and socioeconomically diverse populations to guide PHUs in tailoring their strategies to promote COVID-19 vaccination. This paper presents the community engagement methodology and the lessons learned in applying the methodology. METHODS The community engagement methodology was developed based on integrated knowledge translation (iKT) and community-based participatory research (CBPR) principles. The study involved collaboration with PHUs and local communities in Ontario, Canada to identify priority groups for COVID-19 vaccination, understand factors influencing vaccine uptake and co-design strategies tailored to each community to promote vaccination. Community engagement was conducted across three large urban regions with individuals from Eastern European communities, African, Black, and Caribbean communities and low socioeconomic neighbourhoods. RESULTS We developed and applied a seven-step methodology for conducting community-based behavioural science research: (1) aligning goals with system-level partners; (2) engaging with PHUs to understand priorities; (3) understanding community strengths and dynamics; (4) building relationships with each community; (5) establishing partnerships (community advisory groups); (6) involving community members in the research process; and (7) feeding back and interpreting research findings. Research partnerships were successfully established with members of prioritized communities, enabling recruitment of participants for theory-informed behavioural science interviews, interpretation of findings, and co-design of targeted recommendations for each PHU to improve COVID-19 vaccination uptake. Lessons learned include the importance of cultural sensitivity and awareness of sociopolitical context in tailoring community engagement, being agile to address the diverse and evolving priorities of PHUs, and building trust to achieve effective community engagement. CONCLUSION Effective community engagement in behavioural science research can lead to more inclusive and representative research. The community engagement approach developed and applied in this study acknowledges the diversity of communities, recognizes the central role of PHUs, and can help in addressing complex public health challenges.

Abstract
Because of the COVID-19 pandemic, several health care services, including cardiac rehabilitation (CR), had to transition to virtual delivery, for which formal evaluations are lacking. In this pilot study, we investigated the implementation of a virtual CR program by surveying 30 patients attending virtual CR. Virtual CR was well received, although patients provided recommendations to improve delivery such as offering individual sessions and changing how education materials were delivered. Virtual delivery of CR likely has a role in health care, either independently or as part of a hybrid model; however, further evaluation is required.

Abstract
BACKGROUND Audit and feedback (A&F) is among the most widely used implementation strategies, providing healthcare professionals with summaries of their practice performance to prompt behaviour change and optimize care. Wide variability in effectiveness of A&F has spurred efforts to explore why some A&F interventions are more effective than others. Unpacking the variability of the content of A&F interventions in terms of their component behaviours change techniques (BCTs) may help advance our understanding of how A&F works best. This study aimed to systematically specify BCTs in A&F interventions targeting healthcare professional practice change. METHODS We conducted a directed content analysis of intervention descriptions in 287 randomized trials included in an ongoing Cochrane systematic review update of A&F interventions (searched up to June 2020). Three trained researchers identified and categorized BCTs in all trial arms (treatment & control/comparator) using the 93-item BCT Taxonomy version 1. The original BCT definitions and examples in the taxonomy were adapted to include A&F-specific decision rules and examples. Two additional BCTs ('Education (unspecified)' and 'Feedback (unspecified)') were added, such that 95 BCTs were considered for coding. RESULTS In total, 47/95 BCTs (49%) were identified across 360 treatment arms at least once (median = 5.0, IQR = 2.3, range = 129 per arm). The most common BCTs were 'Feedback on behaviour' (present 89% of the time; e.g. feedback on drug prescribing), 'Instruction on how to perform the behaviour' (71%; e.g. issuing a clinical guideline), 'Social comparison' (52%; e.g. feedback on performance of peers), 'Credible source' (41%; e.g. endorsements from respected professional body), and 'Education (unspecified)' (31%; e.g. giving a lecture to staff). A total of 130/287 (45%) control/comparator arms contained at least one BCT (median = 2.0, IQR = 3.0, range = 0-15 per arm), of which the most common were identical to those identified in treatment arms. CONCLUSIONS A&F interventions to improve healthcare professional practice include a moderate range of BCTs, focusing predominantly on providing behavioural feedback, sharing guidelines, peer comparison data, education, and leveraging credible sources. We encourage the use of our A&F-specific list of BCTs to improve knowledge of what is being delivered in A&F interventions. Our study provides a basis for exploring which BCTs are associated with intervention effectiveness. TRIAL REGISTRATIONS N/A.

Abstract
OBJECTIVES Vaccinating healthcare workers (HCWs) against COVID-19 has been a public health priority since rollout began in late 2020. Promoting COVID-19 vaccination among HCWs would benefit from identifying modifiable behavioural determinants. We sought to identify and categorize studies looking at COVID-19 vaccination acceptance to identify modifiable factors to increase uptake in HCWs. STUDY DESIGN Rapid evidence review. METHODS We searched MEDLINE and Cochrane databases until May 2021 and conducted a grey literature search to identify cross-sectional, cohort, and qualitative studies. Key barriers to, and enablers of, vaccine acceptance were categorized using the Theoretical Domains Framework (TDF), a comprehensive theoretical framework comprising 14 behavioural domains. RESULTS From 19,591 records, 74 studies were included. Almost two-thirds of responding HCWs were willing to accept a COVID-19 vaccine (median = 64%, interquartile range = 50-78%). Twenty key barriers and enablers were identified and categorized into eight TDF domains. The most frequently identified barriers to COVID-19 vaccination were as follows: concerns about vaccine safety, efficacy, and speed of development (TDF domain: Beliefs about consequences); individuals in certain HCW roles (Social/professional role and identity); and mistrust in state/public health response to COVID-19 (Social influences). Routinely being vaccinated for seasonal influenza (Reinforcement), concerns about contracting COVID-19 (Beliefs about consequences) and working directly with COVID-19 patients (Social/professional role and identity) were key enablers of COVID-19 vaccination among HCWs. DISCUSSION Our review identified eight (of a possible 14) behavioural determinants of COVID-19 vaccine acceptance among HCWs that, if targeted, could help design tailored vaccination messaging, policy, campaigns, and programs to support HCWs vaccination uptake.

Abstract
OBJECTIVE Increasing deceased organ donation registration may increase the number of available organs for transplant to help save lives. This study aimed to identify which behaviour change techniques (BCTs; or 'active ingredients') are reported within randomized trials of interventions promoting deceased organ donation registration and of those, which are associated with a larger intervention effect. METHODS We conducted a secondary analysis of 45 trials included in a Cochrane systematic review of deceased organ donation registration interventions. Two researchers used the BCT Taxonomy v1 to independently code intervention content in all trial groups. Outcome data were pooled and we used meta-regression to explore associations between individual and combinations of recurring BCTs and effect on registration intention and/or registration behaviour. RESULTS A total of 27 different BCTs (mean = 3.7, range = 1-9) were identified in intervention groups across the 45 trials. The five most common BCTs were: 'Information about health consequences' (71%); 'Instruction on how to perform the behaviour' (47%); 'Salience of consequences' (40%); 'Adding objects to the environment' (28%); and 'Credible source' (27%). Comparator groups in 20/45 trials also included identifiable BCTs (n = 12, mean = 3.1, range = 1-7). Meta-regression revealed that a combination of the three most common BCTs was associated with a larger intervention effect size for registration behaviour (k = 8, β = .19, p = .02). CONCLUSIONS Trials of deceased organ donation registration interventions focus predominantly on providing information, instruction, and a means to register. While potentially effective, a much wider set of possible BCTs could be leveraged to address known barriers to registration.

Abstract
OBJECTIVES Following acute coronary syndrome (ACS), it is standard practice for stable patients to be discharged as quickly as possible from hospital. If patients are not adequately supported at this time, issues such as readmission can occur. We report findings from an exploratory qualitative study investigating the perceptions and early experiences of patients transitioning from hospitals in the UK and USA to home following ACS. METHODS Within 1 month of discharge, we conducted semi-structured telephone interviews with patients hospitalised for ACS (UK: n = 8; USA: n = 9). Data were analysed using the Framework Method. KEY FINDINGS We identified four superordinate themes. Coping, adjustment and management: Patients were still adjusting to the physical limitations caused by their event but most had begun to implement positive lifestyle changes. Gaps in care transition: Poor communication and organisation postdischarge resulted in delayed follow-up for some patients causing considerable frustration. Quality of care from hospital to home: Patients experienced varied inpatient care quality but had largely positive interactions in primary/community care. Pharmacy input during care transition was viewed favourably in both countries. Medication-taking beliefs and behaviour: Patients reported good initial adherence to treatment but side effects were a concern. CONCLUSIONS ACS patients experienced gaps in care early in the transition from hospital to home. Poor communication and uncoordinated support postdischarge negatively impacted patient experience. Further research is needed to determine how patients' early experiences following ACS can affect longer-term outcomes including healthcare engagement and treatment maintenance.

Abstract
INTRODUCTION In Canada, deceased organ donation provides over 80% of transplanted organs. At the time of death, families, friends or others assume responsibility as substitute decision-makers (SDMs) to consent to organ donation. Despite their central role in this process, little is known about what barriers, enablers and beliefs influence decision-making among SDMs. This study aims to explore the experiences and perspectives of SDMs involved in making decisions around the withdrawal of life-sustaining therapies, end-of-life care and deceased organ donation. METHODS AND ANALYSIS SDMs of 60 patients admitted to intensive care units will be enrolled for this study. Ten hospitals across five provinces in Canada in a prospective multicentre qualitative cohort study. We will conduct semistructured telephone interviews in English or French with SDMs between 6 and 8 weeks after the patient's death. Our sampling frame will stratify SDMs into three groups: SDMs who were not approached for organ donation; SDMs who were approached and consented to donate and SDMs who were approached but did not consent to donate. We will use two complementary theoretical frameworks-the Common-Sense Self-Regulation Model and the Theoretical Domains Framework- to inform our interview guide. Interview data will be analysed using deductive directed content analysis and inductive thematic analysis. ETHICS AND DISSEMINATION This study has been approved by the Centre Hospitalier de l'Université de Montréal Research Ethics Board. The findings from this study will help identify key factors affecting substitute decision-making in deceased organ donation, reasons for non-consent and barriers to achieve congruency between SDM and patient wishes. Ultimately, these data will contribute to the development and evaluation of tools and training for healthcare providers to support SDMs in making decisions about organ donation. TRIAL REGISTRATION NUMBER NCT03850847.

Abstract
Objectives Medication non-adherence is common among patients with acute coronary syndrome (ACS) and is associated with poor clinical outcomes. To date, pharmacists have been underutilised in the delivery of adherence interventions. Across two studies, we assessed the feasibility, acceptability and effectiveness of a novel pharmacy-led intervention for patients hospitalised with ACS. Methods The theory-based intervention was comprised of two personalised sessions addressing perceptual (negative/erroneous treatment beliefs) and practical (suboptimal action planning) barriers to adherence. Study 1: A single-arm, feasibility and acceptability study was conducted to determine proof-of-concept. Pre–post-comparisons using the Beliefs about Medicines Questionnaire-Specific (BMQ-S) were made. Study 2: A non-randomised controlled before–after pilot study was conducted with the intervention delivered by a team of clinical pharmacists. Follow-up data were collected at 6 and 12 weeks post-discharge. Primary outcome measures included the BMQ-S and the Medication Adherence Report Scale 5. Results Study 1: 15 patients received the intervention and reported higher BMQ-S necessity scores post-intervention. The intervention was deemed highly acceptable to patients; therefore, further testing was sought. Study 2: A total of 56 patients were recruited: control (n=29) versus treatment (n=27). At 6-week follow-up, the treatment group had higher BMQ-S necessity scores (M=21.8, SD=3.1) compared with control (M=19.8, SD=2.7; p=0.045), although this effect was not maintained at 12 weeks. No differences were reported in the other outcome measures. Conclusions Although the intervention was acceptable to patients, poor fidelity in delivery raises questions about its feasibility in practice. Furthermore, there was some impact on patients’ beliefs about medications but no effect on adherence. These findings demonstrate the importance of conducting feasibility and acceptability studies when developing adherence innovations in clinical care. Future studies should consider enhancing the training process to ameliorate fidelity issues.

Abstract
We conducted a systematic review and meta-analysis to determine the effectiveness of healthcare provider-led (HCPs) interventions to support medication adherence in patients with acute coronary syndrome (ACS). A systematic search of Cochrane Library, Medline, EMBASE, PsycINFO, Web of Science, IPA, CINAHL, ASSIA, OpenGrey, EthOS, WorldCat and PQDT was undertaken. Interventions were deemed eligible if they included adult ACS patients, were HCP-led, measured medication adherence and randomised participants to parallel groups. Intervention content was coded using the Behaviour Change Technique (BCT) Taxonomy and data were pooled for analysis using random-effects models. Our search identified 8870 records, of which 27 were eligible (23 primary studies). A meta-analysis (n=9735) revealed HCP-led interventions increased the odds of medication adherence by 54% compared to control interventions (k=23, OR 1.54, 95% CI 1.26 to 1.88, I2=57.5%). After removing outliers, there was a 41% increase in the odds of medication adherence with moderate heterogeneity (k=21, OR 1.41, 95% CI 1.21 to 1.65, I2=35.3%). Interventions that included phone contact yielded (k=12, OR 1.63, 95% CI 1.25 to 2.12, I2=32.0%) a larger effect compared to those delivered exclusively in person. A total of 32/93 BCTs were identified across interventions (mean=4.7, SD=2.2) with 'information about health consequences' (BCT 5.1) (19/23) the most common. HCP-led interventions for ACS patients appear to have a small positive impact on medication adherence. While we were able to identify BCTs among interventions, data were insufficient to determine the impact of particular BCTs on study effectiveness. PROSPERO registration number CRD42016037706.

Abstract
OBJECTIVE Medication non-adherence following acute coronary syndrome (ACS) is associated with poor clinical outcomes. A systematic review and meta-analysis were undertaken to identify psychosocial factors associated with medication adherence in patients with ACS. METHODS A search of electronic databases (Cochrane Library, Medline, EMBASE, PsycINFO, Web of Science, International Pharmaceutical Abstracts, CINAHL, ASSIA, OpenGrey, EthOS and WorldCat) was undertaken to identify relevant articles published in English between 2000 and 2014. Articles were screened against our inclusion criteria and data on study design, sample characteristics, predictors, outcomes, analyses, key findings and study limitations were abstracted. RESULTS Our search identified 3609 records, of which 17 articles met our inclusion criteria (15 independent studies). Eight out of ten studies found an association between depression and non-adherence. A meta-analysis revealed that depressed patients were twice as likely to be non-adherent compared to patients without depression (OR=2.00, 95% CI 1.57-3.33, p=0.015). Type D personality was found to predict non-adherence in both studies in which it was measured. Three out of three studies reported that treatment beliefs based on the Necessity-Concerns Framework predicted medication non-adherence and there was some evidence that social support was associated with better adherence. There was insufficient data to meta-analyse all other psychosocial factors identified. CONCLUSION There was some evidence that psychosocial factors, particularly depression, were associated with medication adherence following ACS. Targeting depressive symptoms, screening for Type D personality, challenging maladaptive treatment beliefs, and providing better social support for patients may be useful strategies to improve medication adherence.

Abstract
The aim of this audit was to assess the effect of the Quality Mark programme on the quality of acute care received by older patients by comparing the experiences of staff and older adults before and after the programme. Data from 31 wards in 12 acute hospitals were collected over two stages. Patients and staff completed questionnaires on the perceived quality of care on the ward. Patients rated improved experiences of nutrition, staff availability and dignity. Staff received an increase in training and reported better access to support, increased time and skill to deliver care and improved morale, leadership and teamwork. Problems remained with ward comfort and mealtimes. Overall, results indicated an improvement in ratings of care quality in most domains during Quality Mark data collection. Further audits need to explore ways of improving ward comfort and mealtime experience.

Abstract
The highly polymorphic nonclassical MHC class I chain-related (MIC) genes MICA and MICB encode stress inducible glycoproteins expressed on a variety of epithelial cells including intestinal cells. Interaction with the receptor NKG2D is likely to provide an important costimulatory signal for activation and proliferation of NK cells, activated macrophages and CD8 alphabeta and gammadelta T cells. Fifty-four MICA and 17 MICB alleles have been described to date. Although the functional significance of this polymorphism is not known, the high degree of nonconservative substitution, concentration to the putative ligand-binding site and recent observation that different MICA alleles bind to NKG2D with varying affinity has generated much interest. The MIC genes are attractive functional and positional candidate genes for inflammatory bowel disease susceptibility as a consequence of their position in the HLA region and expression on the gastrointestinal epithelium. We developed a robust, high-resolution PCR-SSP genotyping method that can be incorporated into the standard 'Phototyping' system and which effectively identifies 46 of 54 MICA alleles, and all 17 MICB alleles. We applied this system in combination with microsatellite genotyping of the exon 5 variable number of tandem repeats (VNTR) to the investigation of genetic susceptibility to the inflammatory bowel diseases, ulcerative colitis and Crohn's disease. We studied 248 patients with Crohn's disease, 329 with ulcerative colitis and 354 ethnically matched controls. Linkage disequilibrium patterns between HLA-B, MICA and MICB are presented. Analysis by individual allele or by multilocus haplotype failed to identify any significant disease associations.

Abstract
Long-term follow-up information was obtained for 39 dogs that had undergone surgical excision of nonlymphomatous, small intestinal tumors. For all dogs evaluated in this study, the median survival time was 10 months, and the one- and two-year survival rates were 40.5% and 33.1%, respectively. There was no difference in survival times between dogs with adenocarcinomas (n=23) and dogs with leiomyosarcomas (n=16). Survival times were significantly (p less than 0.0001) shorter for dogs with histological evidence of metastases at the time of surgery (median, 3.0 months) than for dogs with no histiological evidence of metastases (median, 15.0 months).

Abstract
The oral examination in psychiatry for final-year medical students at Wellington and Dunedin School of Medicine, University of Otago, was studied. Between December 1989 and April 1990, 40 medical students were videorecorded during such an examination. The transcripts of the recording of each oral, and at a later date the videorecordings, were individually scored by a panel of six research psychiatrists who were experienced examiners. In addition verbal and non-verbal behaviour was rated using visual analogue scales and the students completed personality and anxiety questionnaires. There was a low level of agreement between research psychiatrists in the allocation of oral marks. The oral score was positively associated with the level of confidence of the student and negatively with anxiety in men.

Abstract
Cyanohydroxybutene (CHB) is reported to be hepatotoxic in male Fischer 344 rats at an oral dose of 300 mg/kg and, while no longer hepatotoxic, pancreatotoxic at 200 mg/kg. In addition, the 200 mg/kg dose causes a persistent elevation in hepatic and pancreatic glutathione (GSH). This study was conducted to determine if smaller doses of CHB could cause GSH elevation in the absence of toxicity. A single oral dose of 100 mg/kg or multiple lower doses (50 mg/kg daily for 3 days or 30 mg/kg for 6 days) caused a significant and persistent increase in pancreatic GSH, although hepatic levels were unchanged. Ten milligrams per kilogram, even daily for 24 days, was without effect on hepatic or pancreatic GSH. Neither a single oral dose of 100 mg/kg nor multiple lower doses were associated with toxicity. However, when either 100 or 50 mg/kg were administered intravenously, pancreatic apoptosis was observed. In animals dosed with 100 mg/kg iv, mixed histiocytic and suppurative inflammation and frank pancreatic necrosis also developed and were associated with elevated plasma lipase and amylase. The animals receiving CHB intravenously also exhibited elevated GSH levels in both pancreas and liver. This study shows that oral doses between 30 and 100 mg CHB/kg can be used to elevate GSH levels without any pancreatotoxicity. However, a single 50 mg CHB/kg dose given intravenously causes apoptosis, while 100 mg/kg causes severe pancreatotoxicity with necrosis.
