Methadone has several unique characteristics that make it an attractive option for pain relief in serious illness, but the safety of methadone has been called into question after reports of a disproportionate increase in opioid-induced deaths in recent years. The American Pain Society, College on Problems of Drug Dependence, and the Heart Rhythm Society collaborated to issue guidelines on best practices to maximize methadone safety and efficacy, but guidelines for the end-of-life scenario have not yet been developed. A panel of 15 interprofessional hospice and palliative care experts from the U.S. and Canada convened in February 2015 to evaluate the American Pain Society methadone recommendations for applicability in the hospice and palliative care setting. The goal was to develop guidelines for safe and effective management of methadone therapy in hospice and palliative care. This article represents the consensus opinion of the hospice and palliative care experts for methadone use at end of life, including guidance on appropriate candidates for methadone, detail in dosing, titration, and monitoring of patients' response to methadone therapy.

In order to improve individual research achievements (IRA), this study investigates which affiliated countries and authors earn the most cited IRAs and whether those types of articles are associated with the number of cited papers on schizophrenia from a leading journal in the field. The Kano model was used for displaying the IRAs. Clusters of medical subject headings (MeSH) were applied to explore the core concepts of a given journal. This study aimed to apply social network analysis (SNA) and an authorship-weighted scheme (AWS) to inspect the association between MeSH terms and IRA. About 2,008 abstracts published between 2012 and 2016 in the journal Schizophrenia Research were downloaded from Pubmed Central using the keyword (Schizophr Res)[Journal] on September 20, 2018. The MeSH terms were clustered by using SNA to separate the core concepts and compare the differences in bibliometric indices (i.e., h, Ag, x and author impact factor or AIF). Visual dashboards were shown on Google Maps. Results indicate that (1) the US, the UK, and Canada earn the highest x-index; (2) the top one author from the US has the highest x-index (= 5.73 with x-core at cited = 16.44 and citable = 2); (3) the article type of schizophrenic psychology shows distinctly higher frequencies than others; and (4) article types are associated with the number of cited papers. Four approaches of the Kano model, SNA, MeSH terms, and AWS can be accommodated to display IRAs, classify article types, and quantify coauthor contributions in the article byline, respectively, and applied to other scientific disciplines in the future, not just in this specific journal.

Introduction: Members of the healthcare team must access and share patient information to coordinate interprofessional collaborative practice (ICP). Although some evidence suggests that electronic health records (EHRs) contribute to in-team communication breakdowns, EHRs are still widely hailed as tools that support ICP. If EHRs are expected to promote ICP, researchers must be able to longitudinally study the impact of EHRs on ICP across communication types, users, and physical locations.Objective: This paper presents a data collection and analysis tool, named the Map of the Clinical Interprofessional Communication Spaces (MCICS), which supports examining how EHRs impact ICP over time, and across communication types, users, and physical locations.Methods: The tool's development evolved during a large prospective longitudinal study conducted at a Canadian pediatric academic tertiary-care hospital. This two-phased study [i.e., pre-implementation (phase 1) and post implementation (phase 2)] of an EHR employed a constructivist grounded theory approach and triangulated data collection strategies (i.e., non-participant observations, interviews, think-alouds, and document analysis). The MCICS was created through a five-step process: (i) preliminary structural development based on the use of the paper-based chart (phase 1); (ii) confirmatory review and modification process (phase 1); (iii) ongoing data collection and analysis facilitated by the map (phase 1); (iv) data collection and modification of map based on impact of EHR (phase 2); and (v) confirmatory review and modification process (phase 2).Results: Creating and using the MCICS enabled our research team to locate, observe, and analyze the impact of the EHR on ICP, (a) across oral, electronic, and paper communications, (b) through a patient's passage across different units in the hospital, (c) across the duration of the patient's stay in hospital, and (d) across multiple healthcare providers. By using the MCICS, we captured a comprehensive, detailed picture of the clinical milieu in which the EHR was implemented, and of the intended and unintended consequences of the EHR's deployment. The map supported our observations and analysis of ICP communication spaces, and of the role of the patient chart in these spaces.Conclusions: If EHRs are expected to help resolve ICP challenges, it is important that researchers be able to longitudinally assess the impact of EHRs on ICP across multiple modes of communication, users, and physical locations. Mapping the clinical communication spaces can help EHR designers, clinicians, educators and researchers understand these spaces, appreciate their complexity, and navigate their way towards effective use of EHRs as means for supporting ICP. We propose that the MCICS can be used "as is" in other academic tertiary-care pediatric hospitals, and can be tailored for use in other healthcare institutions. [ABSTRACT FROM AUTHOR]

Background: Metabolic risk factors, low cognitive function and history of depression are known risk factors for future depressive episodes. This paper aims to evaluate the potential interactions between these factors on the risk of a major depressive episodes in middle-age.Methods: Baseline and follow-up data from a population-based study of Quebec, Canada were used. The sample consisted of 1788 adults between 40 and 69 years of age without diabetes. Cognitive function and metabolic risk factors were assessed at baseline. Three cognitive domains were assessed: processing speed, episodic memory and executive function. History of depression was assessed five years later by a clinical interview. Logistic regression analysis was conducted to evaluate interactions between individual metabolic factors, low cognitive function, and depression history.Results: Participants with a comorbidity of at least one metabolic factor, history of depression and low cognitive function had the highest risk of experiencing a depressive episode in middle age. The highest risk was observed in individuals with abdominal obesity, low cognitive function, and a history of depression (OR= 8.66, 95% CI 3.83-19.59). The risks for those with abdominal obesity only, depression history only, and low cognitive function were 1.20 (95%CI 0.71-2.02), 3.10 (95%CI 1.81-5.24), and 1.39 (95%CI 0.72-2.67), respectively.Limitations: Depression was only assessed at follow-up.Conclusion: Metabolic risk factors comorbid with low cognitive function in middle-aged individuals with a history of depression were associated with an increased risk of a future depressive episode. This study highlights the importance of screening for metabolic and cognitive comorbidities in patients with a history of depression. [ABSTRACT FROM AUTHOR]

Objective: This paper uses the Taxonomy of Everyday Self-management Strategies (TEDSS) to provide insight and understanding into the complex and interdependent self-management strategies people with neurological conditions use to manage everyday life.Methods: As part of a national Canadian study, structured telephone interviews were conducted monthly for eleven months, with 117 people living with one or more neurological conditions. Answers to five open-ended questions were analyzed using qualitative content analysis. A total of 7236 statements were analyzed.Results: Findings are presented in two overarching patterns: 1) self-management pervades all aspects of life, and 2) self-management is a chain of decisions and behaviours. Participants emphasized management of daily activities and social relationships as important to maintaining meaning in their lives.Conclusion: Managing everyday life with a neurological condition includes a wide range of diverse strategies that often interact and complement each other. Some people need to intentionally manage every aspect of everyday life.Practice Implications: For people living with neurological conditions, there is a need for health providers and systems to go beyond standard advice for self-management. Self-management support is best tailored to each individual, their life context and the realities of their illness trajectory. [ABSTRACT FROM AUTHOR]

An increasing number of sustainability standards integrate the principle of free, prior and informed consent (FPIC) as a requirement to ensure respect for the rights of Indigenous peoples. FPIC remains a contested norm, due in part to divergences of interpretation and gaps in implementation. Drawing on a typology based on FPIC conceptions, this paper presents a comparative analysis of the Forest Stewardship Council's (FSC) standard development processes in three countries, Canada, Russia and Sweden. The paper investigates the dynamics of designing FPIC requirements and conceptions of FPIC reflected in national standards. Drawing on semi-structured interviews and analysis of written standards, this study finds similarities in terms of the key debates, such as the scope of Indigenous authority and applicability of FPIC to non-Indigenous communities, however underscored by different stakeholder dynamics and outcomes. Despite the structuring presence of International Generic Indicators, different conceptions of FPIC are reflected in national standards. • We develop a typology of FPIC conceptions including: human rights, relational and procedural. • Analysis of FSC standard development processes in Canada, Russia, Sweden reveal divergent views of FPIC between chambers. • Articulations of FPIC in national standards tend toward relational (Canada) and procedural (Russia and Sweden) conceptions.

Abstract: This paper presents a summary of the main international and national regulations for geologic storage of carbon dioxide. The international group includes the EU Directives, London Convention, and OSPAR. For the national regulations, three countries were covered in this study: United States, Canada, and Australia. In addition to these regulations, a group of guidelines and best practice manuals were also included in this study. As discussion, although this paper recognizes that current legislations have contributed for the regulation of this technology, it is still necessary the development of new rules in other regions. Industry will not invest in large CCS plants without such regulations because of high CCS costs and large financial risks related to CCS. [Copyright &y& Elsevier]

Abstract: In this paper, a comparative review of the community forest models prevailing in two countries is made: the province of British Columbia in Canada and Cameroon in Central Africa. A series of assessment criteria emanating from community forest attributes in both jurisdictions were identified and employed as a basis for assessing and comparing the performance of both models. Results of this study revealed that fundamental similarities and differences exist in the two models and none of the models is superior to the other. However, it is argued that when both models are evaluated against specific criteria, one model often exhibits some sort of dominance vis-à-vis the other. To conclude, the paper prescribes a series of recommendations for improving the efficiency and quality of the community forest model in both jurisdictions. [Copyright &y& Elsevier]

Abstract: Highway geometric design in mountainous areas has been a typical challenge. The combination of short horizontal curves and restricted right-of-way is a common ground for contemplating design exception in British Columbia, Canada. In practice, collision modification factors (CMFs) are advocated as quantitative measures of changes in road features on safety. However, in many situations, there are no CMFs in the literature to predict the safety impact of changing particular road features. An important example of these road features is sight distance restriction on horizontal curves. A mechanism for risk measurement has been proposed in earlier work to assist designers in comparing the safety impact of different deviations from sight distance requirements. This paper attempts to answer the questions as to whether it is possible to reduce overall risk and achieve consistency in such reduction without demanding wider right-of-way. This problem was formulated in a multi-objective optimization framework. Following this methodology, it was possible to achieve an average reduction in risk of 25% on the nine critical cross-sections. This reduction in risk was achieved without demanding wider right-of-way and without creating measurable increase in expected collision frequency due to independent re-dimensioning of different geometric elements. On theoretical grounds, this paper represents another step into the direction of developing fully probabilistic geometric design standards. On practical grounds, this paper provides an important decision mechanism that enables the efficient use of available right-of-way for new highway construction. Case studies in this paper have been applied on a major highway development in British Columba, Canada. [Copyright &y& Elsevier]

Abstract Local public health authorities often lack the capacity to adapt to climate change, despite being on the 'front lines' of climate impacts. Upper-level governments are well positioned to create an enabling environment for adaptation and build local public health authorities' capacity, yet adaptation literature has not specified how upper-level governments can build local-level adaptive capacity. In this paper we examine how federal and regional governments can contribute to enabling and supporting public health adaptation to climate change at the local level in federal systems. We outline the local level's self-assessed adaptive capacity for public health adaptation in Canadian and German comparative case studies, in terms of funding, knowledge and skills, organizations, and prioritization, drawing upon 30 semi-structured interviews. Based on interviewees' recommendations and complemented by scientific literature, we develop a set of practical measures that could enable or support local-level public health adaptation. We find that adaptive capacity varies widely between local public health authorities, but most report having insufficient funding and staff for adaptation activities. We propose 10 specific measures upper-level governments can take to build local public health authorities' capacity for adaptation, under the interrelated target areas of: building financial capital; developing and disseminating usable knowledge; collaborating and coordinating for shared knowledge; and claiming leadership. Federal and regional governments have an important role to play in enabling local-level public health adaptation, and have many instruments available to them to fulfill that role. Selecting and implementing measures to enable local public health authorities' adaptive capacity will require tailoring to, and consideration, of the local context and needs. Highlights • Local public health authorities often lack capacity to adapt to climate change. • National and regional governments can play supportive or enabling role. • We propose 10 concrete measures to enable local public health adaptation.

Introduction: Validity of research linking built environments to health relies on the availability and reliability of data used to measure exposures. As cities transform, it is important to track when and where urban changes occur, to provide detailed information for urban health intervention research. This paper presents an online observation method of the implementation of traffic-calmingfeatures using Google Street View Time Machine. The method is used to validate an existingadministrative database detailing the implementation of curb extensions and speed bumps.Methods: Online observation of curb extensions and speed bumps was conducted for four boroughsin Montreal, Canada, in autumn 2016, and compared with administrative data documenting traffic-calming measures implemented between 2008 and 2014. All images available through the Time Machine function between 2007 and 2016 for 708 intervention sites were visualized online. Records in the administrative database were compared to real-world Google Street View observations and tested in terms of sensitivity, specificity, and positive predicted value.Results: Google Street View Time Machine allowed the visualization of a median of seven different dates per street intersection and six dates per street segment. This made it possible to analyze built environment changes within 3,973 distinct time periods at 708 locations. Validation of the administrative data regarding presence of an intervention showed 99% (95% CI=97%, 99%) sensitivity, 58% (95% CI=51%, 64%) specificity, and 77% (95% CI=73%, 81%) positive predictive value.Conclusions: Google Street View Time Machine allowed past (2007-2016) online documentation of microscale urban interventions-curb extensions and speed bumps. The proposed method offers a new way to document historic changes to the built environment, which will be useful for urban health intervention research. [ABSTRACT FROM AUTHOR]

Abstract: This paper uses sequential stochastic dominance procedures to compare the joint distribution of health and income across space and time. It is the first application of which we are aware of methods to compare multidimensional distributions of income and health using procedures that are robust to aggregation techniques. The paper’s approach is more general than comparisons of health gradients and does not require the estimation of health equivalent incomes. We illustrate the approach by contrasting Canada and the US using comparable data. Canada dominates the US over the bottom part of the bi-dimensional distribution of health and income, though not generally over the uni-dimensional distributions of health or income. The paper also finds that welfare for both Canadians and Americans has not unambiguously improved during the last decade over the joint distribution of income and health, in spite of the fact that the uni-dimensional distributions of income have clearly improved during that period.

Background: Ten U.S. states, Canada, and Uruguay have passed laws to legalize the production and sale of cannabis for non-medical purposes. Available research has documented rapidly falling prices and changing product mixes, but many details are not well understood: particularly, the popularity, prices, and product characteristics of different cannabis edibles and extract-based products - each offering different ways to consume cannabis, with unclear health consequences.Methods: This paper analyzes data from Washington's recreational cannabis market, which has recorded over 110 million retail item-transactions from July 2014 to October 2017. Previous research on price and product trends has focused mostly on herbal cannabis, which accounts for the majority, but a decreasing share, of sales. This paper applies advanced text-analytic methods to provide new insights, including (A) estimating potency data for edibles and (B) identifying extract sub-types. Patterns and trends are described, across product types, regarding THC and CBD profiles and price per THC.Results: Extracts accounted for 28.5% of sales in October 2017. Of extracts categorized to subtype, nearly half were identified as "dabs", and another half "cartridges". In October 2017, price per 10 mg THC was roughly $3 among edibles, 70 cents among extract cartridges, and 30-40 cents for other flower and other extracts; solid concentrates offered the lowest priced THC among extract products. Price declines continue but have slowed. High-CBD chemovars are becoming more common, but still are almost non-existent in flower marijuana and rare (1% of sales) among extract products.Conclusion: As Washington's recreational cannabis market has developed over three and a half years, trends identified in that market may serve as an early indication of potential issues in other states. Legislators and regulators in other jurisdictions with commercial non-medical cannabis markets may wish to establish policies responsive to these trends in product popularity, price, and potency.

Background: There is significant interest in comparing countries on many different indicators of social problems and policies. Cross-national comparisons of drug prevalence and policies are often hampered by differences in the approach used to reach respondents and the methods used to obtain information in national surveys. The paper explores how much these differences could affect cross-country comparisons.Methods: This study reports prevalence of drug use according to the most recent national household survey and then adjusts estimates as if all national surveys used the same methodology. The analysis focuses on European countries for which the European Monitoring Centre for Drugs and Drug Addiction reports data, the United States, Canada, and Australia. Adjustment factors are based on US data.Findings: Adjusting for modality differences appears likely to modestly affect the rankings of countries by prevalence, but to an extent that could be important for comparisons. For example, general population surveys suggest that the US had some of the highest cannabis and cocaine prevalence rates circa 2012, but this is partially driven by the use of a modality known to produce higher prevalence estimates. This analysis shows that country rankings are partly an artifact of the mode of interview used in national general population surveys.Conclusions: Our preliminary efforts suggest that cross-national prevalence comparisons, policy analyses and, other projects such as estimating the global burden of disease could be improved by adjusting estimates from drug use surveys for differences in modality. Research is needed to create more authoritative adjustment factors. [ABSTRACT FROM AUTHOR]

Background: This paper includes the voices of people who are members of a peer-led drug user group (SNAP) in Canada who are receiving heroin-assisted treatment (HAT) outside of a clinical trial. Drawing from critical drug studies, we problematize the criteria for severe opioid use disorder (OUD) from the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders, by exploring SNAP members' experiences in relation to heroin-assisted treatment, and examining how SNAP participants' narratives challenge conventional notions of what constitutes severe opioid use disorder.Method: Drawing on critical analysis and research guidelines developed by drug user unions and organizations, and critical methodological frameworks on ethical community-based-and-responsive research for social justice, in this paper we focus on semi-structured interviews conducted with 36 SNAP members at the Vancouver Area Network of Drug Users site in the Downtown Eastside of Vancouver, Canada. We included opened ended questions about experiences prior to receiving HAT, experiences while receiving HAT, experiences of drug use and cessation, and future hopes.Results: Although SNAP participants were diagnosed as suffering from OUD, the DSM-5 criteria for OUD fails to encompass their diverse experiences of opioid use. Nor does the DSM diagnosis capture the complexities of their lived experience. The DSM OUD constructs an idea of addiction and the addicted person based on a list of symptoms thought to be associated with extended use of opioids. The problem with this is that many of these "symptoms" of drug use are, in the case of SNAP participants, tied to contextual issues of living in the DTES, experiencing structural vulnerability, and being the target of punitive drug policies and laws.Conclusion: To label someone as having a severe disorder shifts the focus from political and social issues, including the lived experiences of people who use heroin. The DSM-5 de-contextualizes drug use. How addiction and heroin are constituted has political implications that will determine what types of services and programs will be set up. Treating a disorder, or a person with a disorder, requires a much different approach than understanding heroin use as a habit. SNAP, and their allies, are rupturing conventional ideas about heroin and taken for granted assumptions about people who use heroin. [ABSTRACT FROM AUTHOR]

Recently the continuous wavelet transform has been proposed for interpretation of potential field anomalies. In this paper, we introduced a 2D wavelet based method that uses a new mother wavelet for determination of the location and the depth to the top and base of gravity anomaly. The new wavelet is the first horizontal derivatives of gravity anomaly of a buried cube with unit dimensions. The effectiveness of the proposed method is compared with Li and Oldenburg inversion algorithm and is demonstrated with synthetics and real gravity data. The real gravity data is taken over the Mobrun massive sulfide ore body in Noranda, Quebec, Canada. The obtained results of the 2D wavelet based algorithm and Li and Oldenburg inversion on the Mobrun ore body had desired similarities to the drill-hole depth information. In all of the inversion algorithms the model non-uniqueness is the challenging problem. Proposed method is based on a simple theory and there is no model non-uniqueness on it. [ABSTRACT FROM AUTHOR]

For refugees who undergo permanent resettlement, characteristics of the resettlement context influence their ability to heal from pre-migration persecution and achieve a sense of wellbeing. This ethnographic study examines the impact of place-related determinants on the sense of wellbeing experienced by refugees resettled in a small urban center. The paper reports on the results of in-depth interviews that were conducted with ten former refugees in St. John's, Canada. We found that challenges and coping resources both emerged from the same aspects of the city, including its built environment, natural environment, history, culture, and low ethnic diversity. Future research should attend to how aspects of the resettlement context can simultaneously challenge and support refugees' sense of wellbeing. [ABSTRACT FROM AUTHOR]

This paper is based on a qualitative study conducted in a rural community in British Columbia, Canada. Ethnographic methods were used to: (1) to bring youth voice to the literature on emotional distress; and (2) to capture the ways in which context shapes young peoples' experiences of emotional distress within their everyday lives. Our findings demonstrate how socio-structural contextual factors such as the local economy, geographical segregation, racism, ageism, and cutbacks in health and social service programming operate to create various forms of disconnection, and intersect in young peoples' lives to shape their experiences of emotional distress.

Atomic Energy of Canada Limited (AECL) has developed the subchannel thermalhydraulics code ASSERT-PV for the Canadian nuclear industry. The recently released ASSERT-PV 3.2 provides enhanced models for improved predictions of flow distribution, critical heat flux (CHF), and post-dryout (PDO) heat transfer in horizontal CANDU fuel channels. This paper presents results of an assessment of the new code version against five full-scale CANDU bundle experiments conducted in 1990s and in 2009 by Stern Laboratories (SL), using 28-, 37- and 43-element (CANFLEX) bundles. A total of 15 CHF test series with varying pressure-tube creep and/or bearing-pad height were analyzed. The SL experiments encompassed the bundle geometries and range of flow conditions for the intended ASSERT-PV applications for CANDU reactors. Code predictions of channel dryout power and axial and radial CHF locations were compared against measurements from the SL CHF tests to quantify the code prediction accuracy. The prediction statistics using the recommended model set of ASSERT-PV 3.2 were compared to those from previous code versions. Furthermore, the sensitivity studies evaluated the contribution of each CHF model change or enhancement to the improvement in CHF prediction. Overall, the assessment demonstrated significant improvement in prediction of channel dryout power and axial and radial CHF locations in horizontal fuel channels containing CANDU bundles.

Abstract: In the recent years, by rapid growth of wind power generation in addition to its high penetration in power systems, the wind power prediction has been known as an important research issue. Wind power has a complicated dynamic for modeling and prediction. In this paper, different hybrid prediction models based on neural networks trained by various optimization approaches are examined to forecast the wind power time series from Alberta, Canada. At first, time series analysis is performed based on recurrence plots and correlation analysis to select the proper input sets for the forecasting models. Next, a comparative study is carried out among neural networks trained by imperialist competitive algorithm (ICA), genetic algorithm (GA), and particle swarm optimization approach. The simulation results are representative of the out-performance of ICA in tuning the neural network for wind power forecasting. [Copyright &y& Elsevier]

Abstract: One way to mitigate greenhouse gas emissions is to provide incentives to forest and farm mangers for adopting practices that store greater amounts of carbon in trees and soils. There is strong interest in the use of carbon finance in agriculture and forestry, particularly in developing countries where large proportions of total emissions are land-based, and where there is good technical potential to turn carbon sources into carbon sinks. The development of mechanisms to incentivize bio-carbon storage is limited, however, by the dearth of working examples. In Africa, for example, the few bio-carbon projects that have been put in place have been financed through the voluntary market or the World Bank BioCarbon Fund. One of the few compliance-based offset programs in the world that allows bio-carbon offsets operates wholly in the province of Alberta, Canada. In this paper we draw lessons from a comparative analysis of the Alberta experience with projects in Mozambique and Kenya. The analysis is based on a conceptual framework of actors, functions and incentives in the bio-carbon offset value chain. We identify key success factors in the three cases and conclude that scaling up of successful project experience will require reliable sources of carbon finance, clear institutional frameworks, and much greater participation by both public and private-sector actors in all phases of the bio-carbon value chain.

Abstract: In this paper, hourly, daily and annual solar resource data derived form the latest SUNY solar model (version 3) using visible and infrared satellite data is analysed and compared with ground measured solar data from eighteen northern- latitude locations distributed all across Canada. The statistics of spatial and temporal differences between the two datasets obtained from the two versions of SUNY model, i.e., V1 and V3, are analysed for both global horizontal irradiance (GHI) and direct normal irradiance (DNI). SUNY V3 GHI and DNI data set is also compared to a dataset produced by the MAC3 cloud layer model for ten northern-latitude locations across Canada. The MAC3 model, using ground-based data, is the basis of the weather design input data files referred to in the current Canadian Model National Energy Code. It is also the model used for generating the CWEEDS (Canadian Weather Energy and Engineering Data Sets) long term hourly dataset, which is in turn used to derive the CWEC files (Canadian Weather year for Energy Calculations) also called typical meteorological years. CWEC files are used for design and analysis in various applications, including buildings heating and cooling as well as solar systems. Overall, results show that SUNY V3 has improved slightly compared to SUNY V1 in terms of estimating global and beam irradiance. Comparison of the SUNY V3 beta model with the MAC3 model seems to indicate that SUNY V3 model is resulting in better DNI estimates than those derived by the MAC3 model. Both SUNY V3 and MAC 3 models give similar estimates for GHI. [Copyright &y& Elsevier]

Background: Despite decades of campaigns aimed at reducing tobacco/nicotine (T/N) use and the development of many different T/N reduction and cessation strategies, the impacts on international public health remain significant. Some studies have found an association between medical and non-medical cannabis use and T/N use, although the evidence on whether cannabis/cannabinoids increase or decrease the odds of reducing or ceasing T/N use remain contradictory. This paper explores the self-reported use of cannabis and associated changes in T/N use among a Canadian medical cannabis patient population.Methods: This study examines the impact of medical cannabis on T/N use by comparing self-reported patterns of use before and after the initiation of medical cannabis. Participants completed an online cross-sectional survey examining demographics, patterns of medical cannabis use, and the impact of medical cannabis on the use of T/N and other substances. The survey also included novel measures examining whether patients intended to use medical cannabis to reduce T/N use or had experience with other pharmacological or psychobehavioral T/N cessation strategies. We conducted a series of descriptive analyses and univariate and multivariate logistic regressions to explore the potential association between primary variables of interest and T/N reduction and cessation.Results: In total, the study recruited 2102 individuals, of whom 650 were current or former T/N users. Following initiation of medical cannabis use 320 (49%) T/N users self-reported reductions in use, with 160 (24.6%) reporting no T/N use in the 30 days prior to the survey. Odds of T/N cessation were greater among those who were age 55 or older (Adjusted Odds Ratio [AOR] = 2.56, 95% Confidence Interval [CI] 1.53-4.26), or those who reported >25 T/N uses per day in the pre-period (AOR = 2.11, 95% CI 1.14-3.92). Specific intent to use medical cannabis to quit resulted in significantly greater odds of reducing T/N use (AOR = 2.79, 95% CI 1.49-5.22); however, involvement with traditional T/N cessation treatments (pharmacological or psychobehavioral) was negatively associated with T/N cessation (AOR 0.39, 95% CI 0.18-0.86).Conclusions: Results from this retrospective survey of medical cannabis users suggest that initiation of medical cannabis use was associated with self-reported reductions and/or cessation of T/N use in nearly half of study participants. In light of the significant morbidity, mortality, and health care costs related to T/N dependence, future research should further evaluate the potential of cannabis-based treatments to support efforts to reduce or cease T/N use.

Indigenous Peoples globally are part of the nutrition transition. They may be among the most extreme for the extent of dietary change experienced in the last few decades. In this paper, we report survey data from 44 representative communities from 3 large cultural areas of the Canadian Arctic: the Yukon First Nations, Dene/Métis, and Inuit communities. Dietary change was represented in 2 ways: 1) considering the current proportion of traditional food (TF) in contrast to the precontact period (100% TF); and 2) the amount of TF consumed by older vs. younger generations. Total diet, TF, and BMI data from adults were investigated. On days when TF was consumed, there was significantly less (P < 0.01) fat, carbohydrate, and sugar in the diet, and more protein, vitamin A, vitamin D, vitamin E, riboflavin, vitamin B-6, iron, zinc, copper, magnesium, manganese, phosphorus, potassium, and selenium. Vitamin C and folate, provided mainly by fortified food, and fiber were higher (P < 0.01) on days without TF for Inuit. Only 10-36% of energy was derived from TF; adults > 40 y old consistently consumed more (P < 0.05) TF than those younger. Overall obesity (BMI > or = 30 kg/m(2)) of Arctic adults exceeded all-Canadian rates. Measures to improve nutrient-dense market food (MF) availability and use are called for, as are ways to maintain or increase TF use. [ABSTRACT FROM AUTHOR]

Abstract: This paper puts forward an integrated approach, based on logarithmic mean divisia index (LMDI) – an index decomposition analysis (IDA) method, an artificial neural network (ANN) and a data envelopment analysis (DEA) for the analysis of total energy efficiency and optimization in an industrial sector. The energy efficiency assessment and the optimization of the proposed model use LMDI to decompose energy consumption into activity, structural and intensity indicators, which serve as inputs to the ANN. The ANN model is verified and validated by performing a linear regression comparison between the specifically measured energy consumption and the corresponding predicted energy consumption. The proposed approach utilizes the measure-specific, super-efficient DEA model for sensitivity analysis to determine the critical measured energy consumption and its optimization reductions. The proposed method is validated by its application to determine the efficiency computation and an analysis of historical data as well as the prediction and optimization capability of the Canadian industrial sector.

Abstract: In this paper, we report the results of a three-year research project (2008–2011) that aimed to identify urban environmental health inequities using a photography-mediated qualitative approach adapted for comparative neighbourhood-level assessment. The project took place in Vancouver, Toronto, and Winnipeg, Canada and involved a total of 49 inner city community researchers who compared environmental health conditions in numerous neighbourhoods across each city. Using the social determinants of health as a guiding framework, community researchers observed a wide range of differences in health-influencing private and public spaces, including sanitation services, housing, parks and gardens, art displays, and community services. The comparative process enabled community researchers to articulate in five distinct ways how such observable conditions represented system level inequities. The findings inform efforts to shift environmental health intervention from constricted action within derelict urban districts to more coordinated mobilization for health equity in the city.

Clinical trials for the treatment of schizophrenia now often include cognitive assessments in addition to clinical ratings of symptoms. Recently, these trials have included cross-national assessments. It is not clear if translated psychological tests produce consistent results across different languages. This paper presents the results of a study of the comparability of the results of cognitive assessments in different English-speaking countries and a number of countries where tests were translated into other languages. Performance on tests of executive functioning, verbal and visuo-spatial learning and memory, language skills, psychomotor speed, and vigilance was compared across the first episode patients with schizophrenia (n=301) assessed in six different languages (English, French, Finnish, German, Hebrew, and Afrikaans), including two different countries where patients were assessed in English and other languages: Canada (French) and South Africa (Afrikaans). The variance in performance across the sites tested in English was as large as the variance between English and non-English speakers when all tests were considered. Performance differences across English and other languages were found only for executive functions, vigilance, and psychomotor speed, with executive functioning differences nonsignificant when education was considered. No differences were found between English and non-English speakers in Canada. These results suggest that the translation of tests of memory and verbal skills can lead to consistent results across translated versions of the tests. Differences between countries were greater than differences between languages, suggesting the need to consider representativeness of patient samples in terms of local educational attainment. In general, these data support the validity of cross-national neuropsychological assessments. [Copyright &y& Elsevier]

Background: The recent legalisation of cannabis in Canada by the Federal Government, along with the accompanying laws and regulations of provincial and territorial governments provides an opportunity to assess the expected benefits and harms of legalisation. While the legislative changes have been initiated by the federal government, much of the responsibility for the implementation falls onto the provinces and territories. These jurisdictions are responsible for regulating the wholesale distribution, retail structures, cannabis consumption, as well as a host of other regulations.Methods: Key characteristics of policies outlined are categorised according to a framework previously developed by the authors (2018). The categories are: (1) government regulation or control, (2) social costs that accompany its use, and (3) legal sanctions that accompany its production and use. Towards that end, we develop a framework for a cost benefit analysis (CBA) outlining in some detail the data that is needed to undertake a credible economic evaluation of cannabis policies.Results: Key data issues discussed include consumer surplus, government receipts including legal and regulatory costs, impact on substitutes, change in profits to firms (growers, wholesalers, and retailers), incomes earned in the industry, health and other costs incurred by cannabis users.Discussion: This paper presents a summary of the expected categories of costs and benefits given the various provincial cannabis policies. Additionally, it provides a framework for subsequent cost benefit analyses which can quantify said harms and benefits. [ABSTRACT FROM AUTHOR]

Background: The Alberta Infant Motor Scale (AIMS) has been developed in Canada in the 90ies. The AIMS and its Canadian norms are frequently used across the world to monitor infants' gross motor development. Currently, it is disputed whether the Canadian norms are valid for non-Canadian infants.Aims: To compare scores on the AIMS of Dutch infants with that of the Canadian norms, to compare the sequence of motor milestones in Dutch and Canadian infants, and to establish Dutch AIMS norms.Study Design: Cross-sectional study.Subjects: 1697 infants, aged 2-18 months, representative of the Dutch population (gestational age 39.7 weeks (27-42)).Outcome Measure: AIMS assessments, based on standardized video. Perinatal and social information was obtained by questionnaire and medical records. To create Dutch reference values quantile regression with polynomial splines was used.Results: 1236 Dutch infants (73%) scored below the 50th (P50) percentile of the Canadian norms, 653 (38%) below the P10 and 469 (28%) below the P5. In infants aged 6 to 12 months these values were: 567 infants (81%) < P50, 288 infants (41%) < P10, 201 infants (29%) < P5. The sequence of achievement of motor milestones of Dutch and Canadian infants was similar. Dutch norm-reference values of the AIMS were calculated.Conclusions and Implications: Gross motor development of Dutch infants is considerably slower than that of the Canadian AIMS norms sample. To prevent overdiagnosis of developmental delay and overreferral to paediatric physiotherapy Dutch AIMS norms are required. The paper introduces these norms, including percentile ranks.

Background: There is growing emphasis on the role of digital solutions in supporting chronic disease management. This has the potential to increase the burden patients experience in managing their health by offloading care from the health system to patients. This paper explores the effects of virtual visits on patient burden using an explicit framework measuring both the work patients do to care for their health and the challenges they experience that exacerbate burden.Methods: This mixed methods study evaluates a large pilot implementation of virtual visits (video, audio, and asynchronous messaging with providers) in primary care in Ontario, Canada. Participants were recruited using convenience sampling from patients using a virtual visit platform to complete a semi-structured interview or a survey including a free-text response. We conducted 17 interviews and reviewed 427 free text responses related to explore patients' perceived value and burden of these visits. We used qualitative analyses to map patients' feedback on their experience to the framework on patient burden.Main Findings: Virtual visits appear to reduce the work patients must do to manage their care by 1) improving access, convenience, and time needed for medical appointments, and 2) making it easier to access information and support for chronic disease management. Virtual visits also alleviate patients' perceived burden by improving continuity of care, experience of care, and providing some cost savings.Conclusions: Virtual visits reduced overall patient burden of treatment by decreasing the required patient effort of managing medical appointments and monitoring their health, and by minimizing challenges experienced when accessing care. For regions that want to improve patient experience of care, virtual visits are likely to be of benefit. There is need for further research on the generalizability of the findings herein, particularly for high-needs populations under-represented such as those of low socioeconomic status and those in rural and remote locations.

• The interRAI YJCF identified youth with mental health and substance use problems. • Substance use and traumatic life events were reported for the majority of youth in detention. • CAPs triggered for most youth for interpersonal conflict and traumatic life events. • For half the youth, CAPs were triggered for harm to others and suicidality/purposeful self-harm. Detained youth display substantive mental health and substance use problems. However, Canadian information is limited. The purpose of this study was (1) to assess mental health and substance use problems of youth in residential detention/custody facilities in Ontario, Canada, at intake, using the interRAI Youth Justice in Custodial Facilities (YJCF), and (2) to explore the added value of using the YJCF in addition to the facilities' standard intake tool. This paper presents the findings of this pilot study. Drawing on all 20 youth secure custody facilities in Ontario, Canada, two groups were created through stratified random group assignment: 10 intervention and 10 non-intervention sites. Staff recruited eligible admitted youth aged 16–19 years between November 2014 and May 2016, with 164 in intervention and 143 in non-intervention arms. Substance use and traumatic life events were reported for the majority of youth. For youth who were assessed using the YJCF, a substantial number of integrated evidence-informed care plans, or Collaborative Action Plans (CAPs) were triggered for specific areas of risk and need. The majority of intervention group youth with YJCFs had CAPs triggered for substance use, interpersonal conflict, traumatic life events, education challenges, transitions and family functioning problems, while for almost half the youth, CAPs were triggered for harm to others and suicidality/purposeful self-harm. The YJCF, compared to the standard admission tool, identified a greater percentage of youth with mental health and substance use problems. Implications for providing expanded assessment for youth are discussed. [ABSTRACT FROM AUTHOR]
