INTRODUCTION
Some populations have been less susceptible to reductions in drowning than others. It has been hypothesised that this is due to prevention strategies failing to account for the influence of social determinants (such as ethnicity, socioeconomic status). Populations such as ethnic minorities have been over-represented in injury statistics, however this is not well explored in drowning. This study aims to identify high-risk populations for drowning, risk factors and prevention strategies.
METHODS
A literature review undertaken systematically using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses approach was conducted of peer-reviewed literature in English, published between 1990 and 2018 from high-income countries. Search terms included drowning, water safety, ethnic minority, migrant, and culturally diverse.
RESULTS
In total, 35 articles were included. High-risk populations identified were: ethnic minorities, First Nations/Aboriginal people, migrants and rural residents. Over half (51%) focused on children (0-18 years). Risk factors included social determinants, swimming ability and knowledge, attitudes and behaviour. Four intervention studies were found; two focused on upskilling adults from high-risk populations to increase employment opportunities within the aquatic industry; an evaluation of a 10-year rock fishing safety education project and a learn-to-swim programme for minority children. Proposed prevention strategies included education, practical skills, research, policy and engagement.
DISCUSSION
Limited literature exists pertaining to drowning among adults from high-risk populations. There is a need to increase the sophistication of drowning prevention strategies addressing the disparities in drowning from a culturally appropriate perspective. Acknowledging the role of the social determinants of health in drowning prevention is essential in order to improve drowning outcomes for high-risk populations globally.

INTRODUCTION
Unintentional injuries represent a substantial public health burden among children and adolescents, and previous evidence suggests that there are disparities in injury by socioeconomic status (SES). This paper reports on a systematic review of literature on injury rates among children and adolescents by measures of SES.
METHODS
A systematic literature search was conducted using six electronic databases: MEDLINE, PsycINFO, CINAHL, HealthSTAR, EMBASE, and SportsDiscus. This review considered children ages 19 years and under and publications between 1997 and 2017-representing an update since the last systematic review examined this specific question. Fifty-four articles were summarized based on study and participant descriptions, outcome and exposure, statistical tests used, effect estimates, and overall significance.
RESULTS
Most articles addressed risk factors across all injury mechanisms; however, some focused particularly on burns/scalds, road traffic injuries, falls/drowning cases, and playground/sports injuries. Other studies reported on specific injury types including traumatic dental injuries, traumatic brain injuries, and fractures. The studies were of moderate quality, with a median of 15.5 (95% confidence interval [CI]: 15.34 to 15.66) out of 19. Thirty-two studies found an inverse association between SES and childhood unintentional injury, three found a positive association while twenty were not significant or failed to report effect measures.
CONCLUSION
Given the variability in definition of the exposure (SES) and outcome (injury), the results of this review were mixed; however, the majority of studies supported a relationship between low SES and increased injury risk. Public health practice must consider SES, and other measures of health equity, in childhood injury prevention programming, and policy.

BACKGROUND
Male sex is a consistently reported risk factor for violent suicide. It has been suggested that this association may be driven by so-called male depression - as operationalized by the Gotland Male Depression Scale (GMDS). The aim of this systematic review was to investigate if males dying by or attempting suicide with violent methods, display symptoms compatible with male depression.
METHODS
This review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A systematic search of PubMed, Embase and PsycINFO was performed using search terms covering: male sex, violent suicide/suicide attempt, and symptoms of male depression from the GMDS. Subsequently, a qualitative synthesis of studies meeting predefined inclusion criteria was carried out.
RESULTS
A total of 28 studies reporting on 91,933 violent suicides and 113 violent suicide attempts were included in the qualitative synthesis. The suicide/suicide attempt methods reported in these studies were predominantly shooting, hanging or drowning. The only two symptoms from the GMDS that was reported in relation to violent suicides/suicide attempts was overconsumption of alcohol or drugs and suicide attempts in the biological family. No studies had systematically assessed suicide victims or attempters for symptoms of male depression.
LIMITATIONS
Publication-, selection-, and information biases may have affected this review.
CONCLUSIONS
Symptoms of male depression are rarely reported in relation to violent suicides/suicide attempts. The most likely explanation for this finding is that there has been little focus on this potential association. Future studies should address this void.

: Drowning is a leading cause of unintentional injury related mortality worldwide, and accounts for roughly 320,000 deaths yearly. Over 90% of these deaths occur in low- and middle-income countries with inadequate prevention measures. The highest rates of drowning are observed in Africa. The aim of this review is to describe the epidemiology of drowning and identify the risk factors and strategies for prevention of drowning in Africa. : A review of multiple databases (MEDLINE, CINAHL, PsycINFO, Scopus and Emcare) was conducted from inception of the databases to the 1st of April 2019 to identify studies investigating drowning in Africa. The preferred reporting items for systematic review and meta-analysis (PRISMA) was utilised. : Forty-two articles from 15 countries were included. Twelve articles explored drowning, while in 30 articles, drowning was reported as part of a wider study. The data sources were coronial, central registry, hospital record, sea rescue and self-generated data. Measures used to describe drowning were proportions and rates. There was a huge variation in the proportion and incidence rate of drowning reported by the studies included in the review. The potential risk factors for drowning included young age, male gender, ethnicity, alcohol, access to bodies of water, age and carrying capacity of the boat, weather and summer season. No study evaluated prevention strategies, however, strategies proposed were education, increased supervision and community awareness. There is a need to address the high rate of drowning in Africa. Good epidemiological studies across all African countries are needed to describe the patterns of drowning and understand risk factors. Further research is needed to investigate the risk factors and to evaluate prevention strategies.

The cadaveric alterations that derive from the decomposition of the human body are often investigated and examined in medical autopsies together with any other evidence of thanatological interest. This study aimed to systematically review case-specific characteristics of dental autopsies that reported the pink tooth phenomenon (PTP). The review was performed in October/2018 and followed PRISMA and Cochrane guidelines. Seven databases were searched as primary study sources (PubMed, Scopus, LILACS, SciELO, Web of Science, Science Direct and Embase) and three (OATD, Open Grey and Open Thesis) were searched for "grey literature". Only descriptive studies were collected, namely case reports and case series. The risk of bias among the studies was assessed with The Joanna Briggs Institute Critical Appraisal tool. From each case, the sex and age of the victims were registered, together with the place of body recovery, time of death, cadaveric status, cause of death, and number and position of pink teeth. Additionally, a supplemental quantitative analysis was conducted within a sampled subgroup. Poisson regression with robust variance was used to analyze relative risks of presenting pink teeth according to age and tooth position. Eleven studies out of 1004 were eligible. In total 71 cases of cadavers with pink teeth were reported. Two (2.81%) victims had unknown sex, while 17 (23.95%) were females and 52 (73.24%) were males. The victims were aged between 4 and 85 years (mean age 31.13 ± 13.32). Dental autopsies registered 331 pink teeth (163 anterior, 87 premolars and 81 molars). The age did not influence on presenting an additional pink tooth, regardless of tooth position (p > 0.05). Forensic dentists must be aware of pink teeth in dental autopsies. This is an unspecific phenomenon and must not be misinterpreted in medico-legal investigations.

BACKGROUND
This systematic review of epilepsy mortality systematic reviews evaluates comparative risks, causes, and risk factors for all-cause mortality in people with epilepsy (PWE) to specifically establish the burden of epilepsy-related deaths.
METHODS
MEDLINE and Embase were searched from conception to 26/12/2018 for systematic reviews evaluating all-cause mortality in PWE of any age. Independent study selection, data extraction and quality assessment were performed. Deaths were separated into epilepsy-related and unrelated using a recently published classification system. Outcomes included standardized mortality ratio (SMR) and mortality rate (MR) in a primary analysis of comparative risks, causes, and risk factors for all-cause and epilepsy-related mortality. A narrative synthesis of review findings was used to present results, including from a secondary analysis of individual epilepsy-related death risk factors.
RESULTS
Six moderate or high-quality systematic reviews were included in the primary analysis, evaluating 103 observational studies. All-cause mortality remained similarly high between 1950 and present (median SMR range 2.2-3.4). Africa had the highest SMR (median 5.4, range 2.6-7.2). SMRs were also higher for children <18 years (median 7.5, range 3.1-22.4) than adults (median 2.6, range 1.3-8.7), and for epilepsy-related (median 3.8, range 0.0-82.4,) than unrelated causes (median 1.7, range 0.7-17.6). Structural brain disease conferred the greatest risk for all-cause mortality (SMR range 24.0-41.5). Common epilepsy-related causes included alcohol, drowning, pneumonia, and suicide. In secondary analysis of nine additional systematic reviews, epilepsy-related death risk factors were reported for sudden unexpected death in epilepsy (SUDEP), drowning and suicide.
CONCLUSIONS
Premature all-cause mortality remains a major problem in PWE globally, particularly in children and young adults, with most being epilepsy-related and potentially preventable. SUDEP is only one of several other common and important epilepsy-related causes of death.

OBJECTIVES
Drowning is the second leading cause of death in children. Extracorporeal membrane oxygenation (ECMO) has become the criterion standard therapy to resuscitate the hypothermic drowning victim in cardiac arrest. We present our own experience treating 5 children with hypothermic cardiac arrest in conjunction with a systematic review to analyze clinical features predictive of survival.
METHODS
Our search resulted in 55 articles. Inclusion criteria were as follows: (1) younger than 18 years, (2) ECMO therapy, and (3) drowning. Ten articles met our inclusion criteria. We included studies using both central and peripheral ECMO and salt or fresh water submersions. We compared clinical features of survivors to nonsurvivors.
RESULTS
A total of 29 patients from the 10 different studies met our criteria. Data analyzed included presenting cardiac rhythm, time to initiation of ECMO, submersion time, pH, potassium, lactate, duration of chest compressions, and survival. There was a significant increase in mortality for presenting rhythm of asystole and with hyperkalemia (P < 0.05).
CONCLUSIONS
Extracorporeal membrane oxygenation is an important resuscitation tool for the hypothermic drowning victim. Hyperkalemia and presenting cardiac rhythm correlate with survival although they are not reasons to end resuscitation. More studies are needed to compare the outcomes in using ECMO for the hypothermic drowning victim.

Meta-Analysis
BACKGROUND
Injuries result in substantial number of deaths among children globally. The burden across many settings is largely unknown. We estimated global and regional child deaths due to injuries from publicly available evidence.
METHODS
We searched for community-based studies and nationally representative data reporting on child injury deaths published after year 1990 from CINAHL, EMBASE, IndMed, LILACS, Global Health, MEDLINE, SCOPUS, and Web of Science. Specific and all-cause mortality due to injuries were extracted for three age groups (0-11 months, 1-4 years, and 0-4 years). We conducted random-effects meta-analysis on extracted crude estimates, and developed a meta-regression model to determine the number of deaths due to injuries among children aged 0-4 years globally and across the World Health Organization (WHO) regions.
RESULTS
Twenty-nine studies from 16 countries met the selection criteria. A total of 230 data-points on 15 causes of injury deaths were retrieved from all studies. Eighteen studies were rated as high quality, although heterogeneity was high (I = 99.7%, < 0.001) reflecting variable data sources and study designs. For children aged 0-11 months, the pooled crude injury mortality rate was 29.6 (95% confidence interval (CI) = 21.1-38.1) per 100 000 child population, with asphyxiation being the leading cause of death (neonatal) at 189.1 (95% CI = 142.7-235.4) per 100 000 followed by suffocation (post-neonatal) at 18.7 (95% CI = 11.8-25.7) per 100 000. Among children aged 1-4 years, the pooled crude injury mortality rate was 32.7 (95% CI = 27.3-38.1) per 100 000, with traffic injuries and drowning the leading causes of deaths at 10.8 (95% CI = 8.9-12.8) and 8.8 (95% CI = 7.5-10.2) per 100 000, respectively. Among children under five years, the pooled injury mortality rate was 37.7 (95% CI = 32.7-42.7) per 100 000, with traffic injuries and drowning also the leading causes of deaths at 10.3 (95% CI = 8.8-11.8) and 8.9 (95% CI = 7.8-9.9) per 100 000 respectively. When crude mortality changes over age, WHO regions, and study period were accounted for in our model, we estimated that in 2015 there were 522 167 (95% CI = 395 823-648 630) deaths among children aged 0-4 years, with South East Asia (SEARO) recording the highest number of deaths at 195 084 (95% CI = 159476-230502), closely followed by the Africa region (AFRO) with 176523 (95% CI = 115 040-237 831) deaths. Globally, traffic injuries and drowning were the leading causes of under-five injury fatalities in 2015 with 142 661 (22.0/100 000) and 123 270 (19.0/100 000) child deaths, respectively. The exception being burns in AFRO with 57 784 deaths (38.6/100 000).
CONCLUSIONS
Varying study designs, case definitions, and particularly limited country representation from Africa and South-East Asia (where we reported higher estimates), imply a need for more studies for better population representative estimates. This study may have however provided improved understanding on child injury death profiles needed to guide further research, policy reforms and relevant strategies globally.

Meta-Analysis
BACKGROUND
The WHO advocates a 7-step process to enable countries to develop and implement drowning prevention strategies. We sought to assess, using existing data sources, the drowning situation in Tanzania as a first step in this process.
METHODS
We searched for data on causes of death in Tanzania by reviewing existing literature and global datasets and by in-country networking. Authors and institutions were then contacted to request aggregate data on drowning mortality. Site-specific drowning estimates were combined using a random effects meta-analytic approach. We also tested for evidence of variations in drowning estimates by sex and by age group.
RESULTS
We acquired partial or complete information on drowning deaths for 13 data sources. We found strong evidence for substantial variations between study sites (p<0.001). Combining population-based data, we estimated an average of 5.1 drowning deaths per 100 000 persons per year (95% CI 3.8 to 6.3). The proportions of deaths due to drowning were 0.72% (95% CI 0.55 to 0.88) and 0.94% (95% CI 0.09 to 1.78) combining population-based data and hospital-based data, respectively. Males were at greater risk than females, while both under-five children and adults aged 45 years or more were at greater risk than those aged 5-44 years.
CONCLUSION
Our estimates of drowning burden are broadly in line with the 2016 Global Burden of Disease and the 2015 WHO Global Health Estimates. While this exercise was useful in raising the burden of drowning in Tanzania with policy makers, planning drowning prevention strategies in this country will require a better understanding of which subpopulations are at high risk.

Epilepsy & Behavior : E&B Oct 2018We conducted a systematic review to ascertain the overall mortality and causes of premature mortality in epilepsy.
BACKGROUND
We conducted a systematic review to ascertain the overall mortality and causes of premature mortality in epilepsy.
METHODOLOGY
We searched PubMed and Embase to identify relevant articles reporting mortality in epilepsy. An assessment of the methodological quality and overall quality of evidence of the identified studies was done using appropriate checklists. We extracted data from these studies reporting measures of overall and cause-specific mortality in epilepsy.
RESULTS
Sixty-three articles from fifty-six cohorts met the eligibility criteria, thirty-three population- or community-based and twenty-three hospital- or institutional-based studies. The majority of studies are from high-income countries (HIC). These studies reported overall excess mortality for people with epilepsy, with wide variability reported for population- or community-based studies and from low- and middle-income countries (LMIC). Twenty-seven articles from twenty-three cohorts reported measures of mortality for cause-specific mortality in epilepsy. People with epilepsy from HIC and LMIC have a higher risk of dying from various causes compared with the general population. Those in LMIC, however, have a particularly high chance of dying from external causes such as drowning and suicide. We observed a decrement over time in measures of overall and cause-specific mortality in cohorts.
CONCLUSIONS
Despite the heterogeneity in reports, our findings support the suggestions that people with epilepsy have an increased risk of premature mortality from various causes. Further work is needed to elucidate the mechanisms, to determine biomarkers for predicting those at risk, and to understand the implications of counseling and preventive strategies.
