RESUMEN
Scientific information on violence can be difficult to compile and understand. It is scattered across websites, databases, technical reports and academic journals, and rarely addresses all types of violence. In response, in October 2017 WHO released the Violence Prevention Information System or Violence Info, an online interactive collection of scientific information about the prevalence, consequences, risk factors and preventability of all forms of interpersonal violence. It covers homicide, child maltreatment, youth violence, intimate partner violence, elder abuse and sexual violence.

Language-based differences in unintentional injury are poorly understood, despite the importance of language as a determinant of health. This study assessed inequalities in unintentional injury mortality between Francophones and Anglophones of Quebec, Canada. We calculated age-standardised rates of death by period, region, residential deprivation and cause of injury, and estimated rate ratios for Francophones relative to Anglophones. Francophones had higher unintentional injury mortality rates than Anglophones. Inequalities decreased over time for men, but rates remained 50% higher for Francophones at the end of the study period. Rates were stable for women, but were 30% higher for Francophones compared with Anglophones. Inequalities were larger at age 15-44â years, in urban areas, and for MVCs. Better understanding of risk factors for MVCs may benefit injury prevention in Quebec. Language-based differences in injury mortality warrant attention in other multilingual populations, especially across different demographic, temporal, regional and cause-of-injury groups.

The impact of underreporting or misclassifying suicides as injuries with undetermined intent is rarely evaluated. We assessed whether undetermined injury deaths influenced provincial rankings of suicide in Canada, using 2â 735â 152 Canadians followed for mortality from 1991 to 2001. We found that suicide rates increased by up to 26.5% for men and 37.7% for women after including injuries with undetermined intent, shifting provincial rankings of suicide. Attention to the stigma of suicide and to coding suicides as injuries with undetermined intent is merited for surveillance and prevention.

BACKGROUND: Suicide is a major cause of premature mortality worldwide, but data on its epidemiology in Africa, the world's second most populous continent, are limited. METHODS: We systematically reviewed published literature on suicidal behaviour in African countries. We searched PubMed, Web of Knowledge, PsycINFO, African Index Medicus, Eastern Mediterranean Index Medicus and African Journals OnLine and carried out citation searches of key articles. We crudely estimated the incidence of suicide and suicide attempts in Africa based on country-specific data and compared these with published estimates. We also describe common features of suicide and suicide attempts across the studies, including information related to age, sex, methods used and risk factors. RESULTS: Regional or national suicide incidence data were available for less than one third (16/53) of African countries containing approximately 60% of Africa's population; suicide attempt data were available for <20% of countries (7/53). Crude estimates suggest there are over 34,000 (inter-quartile range 13,141 to 63,757) suicides per year in Africa, with an overall incidence rate of 3.2 per 100,000 population. The recent Global Burden of Disease (GBD) estimate of 49,558 deaths is somewhat higher, but falls within the inter-quartile range of our estimate. Suicide rates in men are typically at least three times higher than in women. The most frequently used methods of suicide are hanging and pesticide poisoning. Reported risk factors are similar for suicide and suicide attempts and include interpersonal difficulties, mental and physical health problems, socioeconomic problems and drug and alcohol use/abuse. Qualitative studies are needed to identify additional culturally relevant risk factors and to understand how risk factors may be connected to suicidal behaviour in different socio-cultural contexts. CONCLUSIONS: Our estimate is somewhat lower than GBD, but still clearly indicates suicidal behaviour is an important public health problem in Africa. More regional studies, in both urban and rural areas, are needed to more accurately estimate the burden of suicidal behaviour across the continent. Qualitative studies are required in addition to quantitative studies.

OBJECTIVES: We investigated whether the installation of a suicide prevention barrier on Jacques-Cartier Bridge led to displacement of suicides to other jumping sites on Montréal Island and Montérégie, Québec, the 2 regions it connects. METHODS: Suicides on Montréal Island and Montérégie were extracted from chief coroners' records. We used Poisson regression to assess changes in annual suicide rates by jumping from Jacques-Cartier Bridge and from other bridges and other sites and by other methods before (1990-June 2004) and after (2005-2009) installation of the barrier. RESULTS: Suicide rates by jumping from Jacques-Cartier Bridge decreased after installation of the barrier (incidence rate ratio [IRR] = 0.24; 95% confidence interval [CI] = 0.13, 0.43), which persisted when all bridges (IRR = 0.39; 95% CI = 0.27, 0.55) and all jumping sites (IRR = 0.66; 95% CI = 0.54, 0.80) in the regions were considered. CONCLUSIONS: Little or no displacement to other jumping sites may occur after installation of a barrier at an iconic site such as Jacques-Cartier Bridge. A barrier's design is important to its effectiveness and should be considered for new bridges with the potential to become symbolic suicide sites.

PURPOSE: Few studies evaluate language-group differences in suicide mortality. This study assessed the suicide mortality gap between Francophones and Anglophones of Quebec, Canada according to age, sex, method, region and socioeconomic deprivation. METHODS: Suicide decedents were extracted from the Quebec death file for 1989-2007 (N = 24,465). Age- and sex-specific suicide mortality rates were calculated for four periods (1989-1993, 1994-1998, 1999-2003, 2004-2007) for Francophones and Anglophones aged ≥10 years. Age-standardized rates of suicide by method, region, and level of social and material deprivation were calculated for each sex. Rate ratios and rate differences were estimated. RESULTS: Suicide rates for Francophones were two to three times higher than rates for Anglophones, and differences were greatest for adults aged 25-64 years. Francophone males had more than two times the rate of suicide by hanging or firearms than Anglophone males. Francophone females had twice the rate of hanging, poisoning or firearm suicide as Anglophone females, although precision was low. Francophone-Anglophone suicide mortality gaps were higher in urban areas despite lower suicide rates, and varied little across levels of social and material deprivation. CONCLUSIONS: There was a large suicide mortality gap between Francophones and Anglophones of Quebec; especially, among adults aged 25-64 years.

AIM: To determine the age and cause groups contributing to absolute and relative socio-economic inequalities in paediatric mortality, hospitalisation and tumour incidence over time. METHODS: Deaths (n= 9559), hospitalisations (n= 834,932) and incident tumours (n= 4555) were obtained for five age groupings (<1, 1-4, 5-9, 10-14, 15-19 years) and four periods (1990-1993, 1994-1997, 1998-2001, 2002-2005) for Québec, Canada. Age- and cause-specific morbidity and mortality rates for males and females were calculated across socio-economic status decile based on a composite deprivation score for 89 urban communities. Absolute and relative measures of inequality were computed for each age and cause. RESULTS: Mortality and morbidity rates tended to decrease over time, as did absolute and relative socio-economic inequalities for most (but not all) causes and age groups, although precision was low. Socio-economic inequalities persisted in the last period and were greater on the absolute scale for mortality and hospitalisation in early childhood, and on the relative scale for mortality in adolescents. Four causes (respiratory, digestive, infectious, genito-urinary diseases) contributed to the majority of absolute inequality in hospitalisation (males 85%, females 98%). Inequalities were not pronounced for cause-specific mortality and not apparent for tumour incidence. CONCLUSIONS: Socio-economic inequalities in Québec tended to narrow for most but not all outcomes. Absolute socio-economic inequalities persisted for children <10 years, and several causes were responsible for the majority of inequality in hospitalisation. Public health policies and prevention programs aiming to reduce socio-economic inequalities in paediatric health should account for trends that differ across age and cause of disease.

OBJECTIVES: Environmental factors associated with winter outdoor falls are poorly understood. This study describes the demographic, spatial and temporal distribution of outdoor falls that occurred in Laval and Montréal Island (Canada) in relation to meteorological conditions. METHOD: Data on falls, including geographic coordinates, were obtained from ambulance services (December 1, 2008 to january 31, 2009). Meteorological (temperature, precipitation levels) and land use data were used for descriptive analysis and mapping. RESULTS: During the study period, 3270 falls required ambulance interventions, of which 960 occurred outdoors. Most people injured outdoors were under 65 years of age (59%). Mapping showed a concentration of outdoor falls in central neighbourhoods and on commercial streets in Montreal. Three episodes of excess falls, representing 47% of all outdoor falls, were preceded by rain and followed by falling temperatures, or were concomitant with freezing rain. CONCLUSION: Our results demonstrate for the first time the distribution of outdoor falls in a densely populated urban setting with a northern climate. To promote active transportation, it is essential to take into account the safety of pedestrian travel. Snow removal and de-icing operations in municipalities should prioritize areas with high pedestrian activity.

INTRODUCTION: Despite evidence of the benefits of exercise, people with Parkinson's disease (PD) often exercise less than recommended. We sought to identify exercise class-related factors associated with the amount of exercise in PD communities. METHODS: We used Parkinson's Outcome Project (POP) data from 3146 people with PD at 19 participating Centers of Excellence (COEs). POP data included self-reported moderate-vigorous exercise (MVE) hours, light physical activity (PA) hours, demographic and disease severity variables. We also collected information about weekly exercise class availability, intensity, cost, and distance from class location to the COE. We examined differences between COE-based and community-based exercise classes using the Akritas test for paired and unpaired samples. We tested associations between class characteristics and exercise hours based on a two-part model: logistic regression on whether a participant does MVE or light PA and linear regression for log-transformed time of exercise. RESULTS: Community-based exercise classes had a significantly higher weekly availability than COE-based classes (class hours per week: 47.5 ± 25.6 vs 6.5 ± 8.6, p < 0.001), a higher percentage of vigorous-intensity classes (24.2 ± 17.8 vs 11 ± 14.7, p < 0.001), and a broader geographic distribution (miles to COE: 12.8 ± 4.6 vs 6.2 ± 5.7, p < 0.001). Greater weekly hours of availability, intensity, and distance to COE were associated with increased MVE and light PA hours among participants who exercised (p < 0.01). Of these, higher weekly class availability explained the most variability in reported exercise hours. CONCLUSION: Parkinson's COEs may be able to increase exercise by facilitating a high weekly availability of exercise classes with higher intensity levels and broader geographical distribution.
RESUMEN
PURPOSE: This article describes the selection of priority indicators for adolescent (10-19 years) health measurement proposed by the Global Action for Measurement of Adolescent health advisory group and partners, building on previous work identifying 33 core measurement areas and mapping 413 indicators across these areas. METHODS: The indicator selection process considered inputs from a broad range of stakeholders through a structured four-step approach: (1) definition of selection criteria and indicator scoring; (2) development of a draft list of indicators with metadata; (3) collection of public feedback through a survey; and (4) review of the feedback and finalization of the indicator list. As a part of the process, measurement gaps were also identified. RESULTS: Fifty-two priority indicators were identified, including 36 core indicators considered to be most important for measuring the health of all adolescents, one alternative indicator for settings where measuring the core indicator is not feasible, and 15 additional indicators for settings where further detail on a topic would add value. Of these indicators, 17 (33%) measure health behaviors and risks, 16 (31%) health outcomes and conditions, eight (15%) health determinants, five (10%) systems performance and interventions, four (8%) policies, programmes, laws, and two (4%) subjective well-being. DISCUSSION: A consensus list of priority indicators with metadata covering the most important health issues for adolescents was developed with structured inputs from a broad range of stakeholders. This list will now be pilot tested to assess the feasibility of indicator data collection to inform global, regional, national, and sub-national monitoring.

BACKGROUND: Few studies have investigated how area-level deprivation influences the relationship between individual disadvantage and suicide mortality. The aim of this study was to examine individual measures of material and social disadvantage in relation to suicide mortality in Canada and to determine whether these relationships were modified by area deprivation. METHODS: Using the 1991-2001 Canadian Census Mortality Follow-up Study cohort (N = 2,685,400), measures of individual social (civil status, family structure, living alone) and material (education, income, employment) disadvantage were entered into Cox proportional hazard models to calculate hazard ratios (HR) and 95% confidence intervals (CI) for male and female suicide mortality. Two indices of area deprivation were computed - one capturing social, and the other material, dimensions - and models were run separately for high versus low deprivation. RESULTS: After accounting for individual and area characteristics, individual social and material disadvantage were associated with higher suicide mortality, especially for individuals not employed, not married, with low education and low income. Associations between social and material area deprivation and suicide mortality largely disappeared upon adjustment for individual-level disadvantage. In stratified analyses, suicide risk was greater for low income females in socially deprived areas and males living alone in materially deprived areas, and there was no evidence of other modifying effects of area deprivation. CONCLUSIONS: Individual disadvantage was associated with suicide mortality, particularly for males. With some exceptions, there was little evidence that area deprivation modified the influence of individual disadvantage on suicide risk. Prevention strategies should primarily focus on individuals who are unemployed or out of the labour force, and have low education or income. Individuals with low income or who are living alone in deprived areas should also be targeted.

OBJECTIVE: To determine the leading causes of fatal injury for urban South African children aged 0-14 years, the distribution of those causes and the current potential for safety improvements. METHODS: We obtained injury surveillance data from the National Injury Mortality Surveillance System 2001-2003 for six major South African cities varying in size, development and sociodemographic composition. We calculated age-adjusted rates, by sex, population group and city, for death from the five leading causes of fatal injury as well as population attributable risks (PARs). FINDINGS: The leading causes of fatal injury in childhood included road traffic injuries - among vehicle passengers and especially among pedestrians - drowning, burns and, in some cities, firearm injuries. Large differences in PARs were observed, particularly for population groups and cities. Disparities between cities and between population groups were largest for deaths from pedestrian injuries, while differences between boys and girls were greatest for drowning deaths. CONCLUSION: In the face of the high variability observed between cities and population groups in the rates of the most common types of fatal injuries, a safety agenda should combine safety-for-all countermeasures - i.e. lowering injury rates for all - and targeted countermeasures that help reduce the burden for those at greatest risk.

The typical circumstances of suicide occurrence in post-apartheid urban South Africa are described. Data comprise suicide cases from all geographical locations (urban municipalities) where an injury surveillance system has full coverage. Typical patterns were identified by means of a classification technique applied to eight variables descriptive of the events, their victims, and the suicide level of the cities. Six suicide mortality patterns were identified, most being race-specific and each associated with particular suicide methods. Preventive strategies should target local communities and specific population subgroups, and be appropriate and responsive to their sociocultural needs.

UNLABELLED: Knowledge of suicide epidemiology in low- and middle-income settings is important for both well-tailored policies and an increased global understanding of suicide macro-determinants. Adolescents are an important target group in that respect, and those from South Africa are a particular concern, given the additional challenges associated with dramatic political, economic, and health transition. OBJECTIVE: This study presents a profile of adolescent suicide occurrence and sex, race, and city differences. STUDY GROUP: Adolescents aged 10-19 years in post-apartheid urban South Africa. METHODS: Sex-, race- and city-specific suicide rates were calculated for two age groups (10-14, 15-19 years). Using logistic regression, odds ratios were compiled, first adjusting for age, then additionally for sex, race, and city. Female subjects, those classified as 'coloured' (denoting mixed racial origin), and those living in Tshwane were used as reference groups. Proportions (with 95% confidence intervals) of leading suicide methods were compared. RESULTS: Suicide rates were considerably higher among older adolescents and varied by sex, race, and city. Males had more than twice the odds of committing suicide compared with females. In the fully adjusted model, differences between races were not significant, but city-level differences remained. The leading suicide method was hanging for males and both hanging and poisoning for females. CONCLUSIONS: In contemporary urban South Africa, male sex, and city of residence, but not race, were associated with the commission of adolescent suicide, which tends to occur by quite specific methods. The findings warrant research into the possible underlying contextual, demographic, and individual mechanisms.

Although it is not a legal requirement in South Africa, medical practitioners determine the manner of injury death for a surveillance system that is currently the only source of epidemiological data on suicide. This study assessed the accuracy of suicide data as recorded in the system using the docket produced from standard medico-legal investigation procedures as the gold standard. It was conducted in one of three cities where the surveillance system had full coverage for the year 2000. In the medico-legal system, one-third of cases could not be tracked, had not been finalized, or had unclear outcomes. For the remaining cases, the sensitivity, specificity, and positive and negative predictive values were generally high, varying somewhat across sex and race groups. Poisoning, jumping, and railway suicides were more likely than other methods to be misclassified, and were more common among females and Whites. The study provides encouraging results regarding the use of medical practitioner expertise for the accurate determination of suicide deaths. However, suicides may still be underestimated in this process given the challenge of tracing disguised suicides and without the careful examination of potential misclassifications of true suicides as unintentional deaths.

New surgical procedures, imaging modalities, and medical devices have improved therapy for many patients and made treatment possible for others who have had few options in the past. In February 2004, the National Heart, Lung, and Blood Institute's (NHLBI) Advisory Council proposed that the institute evaluate the status and future directions in cardiac surgery. In response to this recommendation, the NHLBI convened a working group of cardiac surgeons on May 7 and 8, 2004, to assess the state of cardiac surgery research, identify critical gaps in current knowledge, determine areas of opportunity, and obtain specific recommendations for future research activities. The working group discussed surgical revascularization, novel surgical approaches, valvular research directions, biotechnology and cell-based therapy, heart failure, imaging modalities, and barriers to clinical research and presents its recommendations here.

In this study the importance of living area circumstances for suicide mortality was explored. Suicide mortality was assessed across race and sex groups in a South African city and the influence of area-based compositional and sociophysical characteristics on suicide risk was considered. Suicide mortality rates are highest among Whites, in particular White males. Main--and independent--dimensions of the living circumstances of residential areas (i.e., socioeconomic circumstances, economic need, and matrimony) influence age-adjusted suicide rates for both sexes but minimally so for race groups. Less favorable clusters of circumstances have a protective effect.

PATIENT: Male, 62. FINAL DIAGNOSIS: Bipolar disorder. SYMPTOMS: Bordeline personality disorder. MEDICATION: - CLINICAL PROCEDURE: Bed bug infestation. SPECIALTY: Psychiatry. OBJECTIVE: Unusual clinical course. BACKGROUND: In the past decade, bed bug infestations have been increasingly common in high income countries. Psychological consequences of these infestations are rarely examined in the scientific literature. CASE REPORT: We present a case, based on a coroner's investigation report, of a woman with previous psychiatric morbidity who jumped to her death following repeated bed bug infestations in her apartment. Our case report shows that the bed bug infestations were the likely trigger for the onset a negative psychological state that ultimately led to suicide. CONCLUSIONS: Given the recent surge in infestations, rapid action needs to be taken not only in an attempt to control and eradicate the bed bugs but also to adequately care for those infested by bed bugs.
RESUMEN
OBJECTIVE: We examined the leading causes of unintentional injury and suicide mortality in adults across the urban-rural continuum. METHODS: Injury mortality data were drawn from a representative cohort of 2,735,152 Canadians aged ≥ 25 years at baseline, who were followed for mortality from 1991 to 2001. We estimated hazard ratios and 95% confidence intervals for urban-rural continuum and cause-specific unintentional injury (i.e., motor vehicle, falls, poisoning, drowning, suffocation, and fire/burn) and suicide (i.e., hanging, poisoning, firearm, and jumping) mortality, adjusting for socioeconomic and demographic characteristics. RESULTS: Rates of unintentional injury mortality were elevated in less urbanized areas for both males and females. We found an urban-rural gradient for motor vehicle, drowning, and fire/burn deaths, but not for fall, poisoning, or suffocation deaths. Urban-rural differences in suicide risk were observed for males but not females. Declining urbanization was associated with higher risks of firearm suicides and lower risks of jumping suicides, but there was no apparent trend in hanging and poisoning suicides. CONCLUSION: Urban-rural gradients in adults were more pronounced for unintentional motor vehicle, drowning, and fire/burn deaths, as well as for firearm and jumping suicide deaths than for other causes of injury mortality. These results suggest that the degree of urbanization may be an important consideration in guiding prevention efforts for many causes of injury fatality.
