Abstract
The aim of this study was to investigate whether gender was an effect modifier of the relationship between three psychosocial job stressors and sleep quality, in a representative sample of 7280 employed Australians. We conducted linear regressions and effect measure modification analyses. Low job control, high job demands and low job security were associated with poorer sleep quality. There was evidence of effect modification of the relationship between job security and sleep quality by gender on the additive scale, indicating that the combined effect of being male and having low job security is greater than the summed interactive effect.

Abstract
BACKGROUND Unemployment and being not in the labour force (NILF) are risk factors for suicide, but their association with self-harm is unclear, and there is continuing debate about the role of confounding by prior mental health conditions. We examine associations between employment status and self-harm and suicide in a prospective cohort, taking into account prior mental-health-related factors. METHODS We used linked data from the New Zealand Integrated Data Infrastructure. The outcomes were chosen to be hospital presentation for self-harm and death by suicide. The exposure was employment status, defined as employed, unemployed, or NILF, measured at the 2013 Census. Confounders included demographic factors and mental health history (use of antidepressant medication, use of mental health services, and prior self-harm). Logistic regression was used to model effects. Analyses were stratified by gender. RESULTS For males, unemployment was associated with an increased risk of suicide [odds ratio (OR): 1.48, 95% confidence interval (CI): 1.20-1.84] and self-harm (OR: 1.55, 95% CI: 1.45-1.68) after full adjustment for confounders. NILF was associated with an increased risk of self-harm (OR: 1.43, 95% CI: 1.32-1.55), but less of an association was seen with suicide (OR: 1.19, 95% CI: 0.94-1.49). For females, unemployment was associated with an increased risk of suicide (OR: 1.30, 95% CI: 0.93-1.80) and of self-harm (OR: 1.52, 95% CI: 1.43-1.62), and NILF was associated with a similar increase in risk for suicide (OR: 1.31, 95% CI: 0.98-1.75) and self-harm (OR: 1.32, 95% CI: 1.26-1.40). DISCUSSION Exclusion from employment is associated with a considerably heightened risk of suicide and self-harm for both men and women, even among those without prior mental health problems.

Abstract
PURPOSE To assess the quality of the research about how employment conditions and psychosocial workplace exposures impact the mental health of young workers, and to summarize the available evidence. METHODS We undertook a systematic search of three databases using a tiered search strategy. Studies were included if they: (a) assessed employment conditions such as working hours, precarious employment, contract type, insecurity, and flexible work, or psychosocial workplace exposures such as violence, harassment and bullying, social support, job demand and control, effort-reward imbalance, and organizational justice; (b) included a validated mental health measure; and (c) presented results specific to young people aged ≤ 30 years or were stratified by age group to provide an estimate for young people aged ≤ 30 years. The quality of included studies was assessed using the Risk of Bias in Non-randomized Studies of Exposures (ROBINS-E) tool. RESULTS Nine studies were included in the review. Four were related to employment conditions, capturing contract type and working hours. Five studies captured concepts relevant to psychosocial workplace exposures including workplace sexual harassment, psychosocial job quality, work stressors, and job control. The quality of the included studies was generally low, with six of the nine at serious risk of bias. Three studies at moderate risk of bias were included in the qualitative synthesis, and results of these showed contemporaneous exposure to sexual harassment and poor psychosocial job quality was associated with poorer mental health outcomes among young workers. Longitudinal evidence showed that exposure to low job control was associated with incident depression diagnosis among young workers. CONCLUSIONS The findings of this review illustrate that even better studies are at moderate risk of bias. Addressing issues related to confounding, selection of participants, measurement of exposures and outcomes, and missing data will improve the quality of future research in this area and lead to a clearer understanding of how employment conditions and psychosocial workplace exposures impact the mental health of young people. Generating high-quality evidence is particularly critical given the disproportionate impact of COVID-19 on young people's employment. In preparing for a post-pandemic world where poor-quality employment conditions and exposure to psychosocial workplace exposures may become more prevalent, rigorous research must exist to inform policy to protect the mental health of young workers.

Abstract
Emerging adulthood is a neglected phase of the life course in health research. Health problems and risk behaviors at this time of life can have long-term consequences for health. The 2016 Lancet Commission on Adolescent Health and Wellbeing reported that the influence of socioeconomic factors was under-researched among adolescents and young adults. Moreover, the influence of socioeconomic factors on health has been little researched specifically in emerging adult men. We aimed to investigate associations between socioeconomic disadvantage and mental health, suicidal behavior, and substance use in young adult Australian men. Logistic regression was used to examine the association between Year 12 (high school) completion and area disadvantage on mental health, suicidal behavior, and substance use in 2,281 young men age 18-25 participating in the Australian Longitudinal Study on Male Health (Ten to Men). In unadjusted analysis both Year 12 non-completion and area disadvantage were associated with multiple adverse outcomes. In adjusted analysis Year 12 non-completion, but not area disadvantage, was associated with poorer mental health, increased odds of suicidal behavior, and substance use. Retaining young men in high school and developing health-promotion strategies targeted at those who do exit education early could both improve young men's mental health and reduce suicidal behavior and substance use in emerging adulthood.

Abstract
OBJECTIVES We sought to estimate risk of poor self-rated health (SRH) following exposure to disability-related and other forms of overt discrimination in a cohort of working age adults. STUDY DESIGN The study design is a population-based cohort survey. METHODS Secondary analysis of data collected in Waves 1 and 2 of the UK's Life Opportunities Survey which at Wave 2 involved the participation of 12,789 working age adults. Adjusted prevalence rate ratios were used to estimate the impact of exposure to disability and non-disability discrimination on two measures of SRH at Wave 2, controlling for SRH status at Wave 1. RESULTS Exposure to disability discrimination in the previous year was reported by 3.9% of working age British adults. Other forms of discrimination were reported less frequently (age: 3.7%, ethnicity: 2.5%, gender: 1.6%, religion: 0.8%, sexual orientation: 0.4%). In all analyses, there were stronger associations between exposure to disability discrimination and poor SRH at Wave 2 when compared with exposure to other forms of discrimination. CONCLUSIONS Disability discrimination represents a violation of human rights. It is also likely to be a major contributor to the health inequities experienced by working age adults with disability.

Abstract
BACKGROUND There is a well-established gender divide among people who do and do not seek professional help from mental health professionals. Females are typically more likely to report, and seek help for, mental health problems. The current paper sought to examine the role of employment context on help-seeking for mental health issues. We hypothesised that men and women in male-dominated occupations would be less likely to seek help than those in non-male-dominated occupations. METHODS Data from the Household, Income and Labour Dynamics in Australia survey were used. Help-seeking, measured in 2013, was defined as whether a person reported attending a mental health professional in the 12 months prior to the survey. The exposure, male- and non-male-dominated occupations (measured in 2012), was defined using census data based on self-reported occupation. Analyses were stratified by gender and controlled for relevant confounders (measured in 2012), including mental health and prior help-seeking. We conducted multivariate logistic and propensity score analyses to improve exchangeability of those exposed and unexposed. RESULTS For males, being in a male-dominated occupation was independently associated with reduced likelihood of help-seeking (OR 0.66, 95% CI 0.46-0.95) in the adjusted model, although this result fell just out of significance in the propensity score analysis. There was no independent effect of being in a male-/non-male-dominated occupation for help-seeking among women. CONCLUSIONS Results suggest that male-dominated occupations may negatively influence help-seeking among males. There is a need for more research to understand this relationship and for workplace-based prevention initiatives.

Abstract
Branchio-oto-renal spectrum disorders are rare genetic entities with variable penetrance and concurrently display a wide phenotypic variation. A common issue to syndromic children is a propensity for difficult bag-mask ventilation, intubation or both. Unfortunately, there is no uniformity of this challenge, assessment strategy or management plan. This case with features of branchio-otic syndrome provided the opportunity to examine several aspects of paediatric anaesthetic airway management. The child was booked for branchial cyst removal but appeared to have other features of abnormal branchial cleft development. An outline of the executed anaesthetic plan is presented and discussed. Three different techniques were sequentially tried in this patient before the airway was secured. Various case reports in the literature inconsistently describe easy to very difficult airway management in children with branchio-oto-renal spectrum disorders. Branchial arch dysgenesis is almost always associated with difficult direct laryngoscopy. There is undoubtedly no singular way to ideally manage a child with a difficult airway. Many tools for difficult airways are available. However, despite the improvement of difficult paediatric airway equipment, it would appear that for the anaesthetist the flexible bronchoscope remains an indispensable tool.

Abstract
Employment is a fundamental Social Determinant of Health known to have large impacts on mental health and other health outcomes. Across many countries of the world, people with disabilities are much more likely to be unemployed and looking for work than those without disabilities. The deprivation of employment opportunities is likely to have notable impacts on the health of people with disabilities. In this commentary, we outline the concept of "disabling working environments," which are defined as the range of experiences that affect the likelihood of people with disabilities in obtaining and maintaining quality employment which may then affect a disabled person's health. Disabling working environments are comprised of the following three mutually reinforcing components: 1) Differential selection into work; 2) Selection into certain types of jobs and exposure to poor psychosocial working environments when in employment, and; 3) Differential selection out of work (e.g., leaving employment at an earlier age than those who do not have a disability). We argue that policy and intervention design should consider the life course effects of employment on the mental health of people with disabilities.

Abstract
BACKGROUND Construction workers are at elevated risk of suicide. MATES in Construction (MATES) is one of the few suicide prevention programs that explicitly address this problem. The MATES program includes an integrated system of services that supports prevention, early intervention and recovery (i.e., primary, secondary and tertiary prevention) for mental health problems among construction workers. In this protocol, we describe a proposed evaluation of MATESmobile, an electronic platform which will be accessed by workers who have undergone MATES training. METHODS/DESIGN In this protocol, we describe a Randomised Controlled Trial (RCT) which seeks to assess whether MATESmobile results in improved literacy regarding suicide prevention, and improved help-seeking and help-offering attitudes among those who have attended MATES training. Secondary outcomes include changes in suicide ideation, suicide attempt and psychological distress. Workers will be recruited prior to MATES face-to-face training. In total, 295 workers will be randomly assigned to the intervention condition (MATESmobile + face-to-face training) and 295 will be randomly allocated to the control (face-to-face training). The intervention will run for 8 weeks. Assessments will be run immediately post intervention, and at 3, 6, and 12 months DISCUSSION: MATESmobile offers the potential to reinforce and enhance the effects of face-to-face training, resulting in greater skills and knowledge in suicide prevention, as well as a reduction in suicidality and distress. TRIAL REGISTRATION This trial is registered with the Australian New Zealand Clinical Trials Registry ( ACTRN12619000625178 ; 26 April 2019).

Abstract
Males employed in the construction industry are at greater risk of suicide than other employed males. It is plausible that a high level of stigma against mental health problems explains the elevated rates of suicide among this group. This study sought to test the effectiveness of an electronic mental health stigma intervention on suicide ideation, communication about suicide and attempts. Participants were randomly assigned to receive either a series of brief contact interventions over a 6-week period or a wait list control. Suicidal ideation, communication about suicide and suicide attempts were assessed using the Suicidal Behaviors Questionnaire-Revised at post-intervention. We used linear regression to assess effectiveness at post-intervention, adjusting for relevant covariates using both conventional methods and a propensity score approach. Results indicate that the intervention had no significant impact on suicidal thoughts, communication or suicide attempts. There was some indication that individuals in the intervention group reported a slight increase in attempts and communication about suicide. These observations underscore an urgent need for more research to understand the complex and nuanced relationship between stigma and suicide in non-clinical populations.

Abstract
BACKGROUND This study sought to compare the prevalence of bullying victimization between adolescents with and without a disability and between adolescents with and without borderline intellectual functioning or intellectual disability (BIF/ID). We also sought to assess whether the relationships between either disability or BIF/ID and bullying victimization vary by gender and parental education. METHODS The sample included 3,956 12- to 13-year-old adolescents who participated in Wave 5 of the Longitudinal Study of Australian Children. Three indicators of bullying were used: physical bullying victimization, social bullying victimization, and "any bullying victimization." We used Poisson regression to obtain the prevalence risk ratios (PRR) of bullying by disability status adjusting for potential confounders. RESULTS In adjusted models, we found evidence that social bullying victimization was more prevalent among adolescents with a disability than those without a disability (PRR 1.29, 95% confidence interval [CI] 1.06-1.42) and between adolescents with BIF/ID than those without (PRR 1.24, 95% CI 1.07-1.44). Adolescents with BIF/ID were also more likely to experience "any bullying victimization"(PRR 1.10, 95% CI 1.00-1.22). Having a disability and living in a family with low parental education were associated with an elevated risk of social bullying victimization BIF/ID. CONCLUSIONS Adolescents with disabilities and BIF/ID are at elevated risk of social bullying victimization. School-based antibullying initiatives should concentrate on enhancing the inclusion of adolescents with disabilities, with an emphasis on adolescents from disadvantaged backgrounds.

Abstract
BACKGROUND Emergency and protective services personnel (e.g., police, ambulance, fire-fighters, defence, prison and security officers) report elevated levels of job stress and health problems. While population-level research is lacking, there has been some research suggesting suicide rates may be elevated in emergency and protective services. OBJECTIVES This paper compares suicide rates between emergency and protective services occupational groups over a 12-year period (2001-2012) in Australia. METHOD Labour force data was obtained from the 2006 Australian Census. Suicide data was obtained from the National Coroners Information System (NCIS). Negative binomial regression was used to estimate the association between suicide and employment as an emergency or protective service worker (including prison and security officers) over the period 2001-2012, as compared to all other occupations. Information on suicide method was extracted from the NCIS. RESULTS The age-adjusted suicide rate across all emergency and protective service workers was 22.4 (95% CI 19.5 to 25.2) per 100,000 in males and 7.8 in females (95% CI 4.6 to 11.00), compared to 15.5 per 100,000 (95% CI 15.2 to 15.9) for males and 3.4 (95% CI 3.2 to 3.6) for females in other occupations. The highest risk by subgroup was observed among those employed in the defence force, prison officers, and ambulance personnel. The major method of death for all occupational groups was hanging. CONCLUSIONS Our results clearly highlight the need for suicide prevention among emergency and protective service occupations.

Abstract
BACKGROUND A suicide cluster is defined as a higher number of observed cases occurring in space and/or time than would typically be expected. Previous research has largely focused on identifying clusters of suicides, while there has been comparatively limited research on clusters of suicide attempts. We sought to identify clusters of both types of behaviour, and having done that, identify the factors that distinguish suicide attempts inside a cluster from those that were outside a cluster. METHODS We used data from Western Australia from 2000 to 2011. We defined suicide attempts as admissions to hospital for deliberate self-harm and suicides as deaths due to deliberate self-harm. Using an analytic strategy that accounted for the repetition of attempted suicide within a cluster, we performed spatial-temporal analysis using Poisson discrete scan statistics to detect clusters of suicide attempts and clusters of suicides. Logistic regression was then used to compare clustered attempts with non-clustered attempts to identify risk factors for an attempt being in a cluster. RESULTS We detected 350 (1%) suicide attempts occurring within seven spatial-temporal clusters and 12 (0.6%) suicides occurring within two spatial-temporal clusters. Both of the suicide clusters were located within a larger but later suicide attempt cluster. In multivariate analysis, suicide attempts by individuals who lived in areas of low socioeconomic status had higher odds of being in a cluster than those living in areas of high socioeconomic status [odds ratio (OR) = 29.1, 95% confidence interval (CI) = 6.3-135.5]. A one percentage-point increase in the proportion of people who had changed address in the last year was associated with a 60% increase in the odds of the attempt being within a cluster (OR = 1.60, 95% CI = 1.29-1.98) and a one percentage-point increase in the proportion of Indigenous people in the area was associated with a 7% increase in the suicide being within a cluster (OR = 1.07, 95% CI = 1.00-1.13). Age, sex, marital status, employment status, method of harm, remoteness, percentage of people in rented accommodation and percentage of unmarried people were not associated with the odds of being in a suicide attempt cluster. CONCLUSIONS Early identification of and responding to suicide clusters may reduce the likelihood of subsequent clusters forming. The mechanisms, however, that underlie clusters forming is poorly understood.

Abstract
BACKGROUND Availability of lethal means is a significant risk factor for suicide. This study investigated whether occupations with greater access to lethal means had higher suicide rates than those without access, and further, whether this relationship differed for females versus males. METHODS A retrospective mortality study was conducted across the Australian population over the period 2001 to 2012. Data from the Australian Bureau of Statistics, which collects Census information on occupation for the Australian population, and the National Coroners Information System, which records information on suicide deaths, were combined. Employed suicide records were coded by occupation and work-related access to lethal means. Descriptive analysis and negative binomial regression were used to assess the relationship between access to means and suicide. RESULTS Persons in occupations with access to firearms, medicines or drugs, and carbon monoxide more frequently used these methods to end their lives than those without access to means. Females employed in occupations with access to means had suicide rates that were 3.02 times greater (95% CI 2.60 to 3.50, p < 0.001) than those employed in occupations without access. Males in occupations with access had suicide rates that were 1.24 times greater than those without access (95% CI 1.16 to 1.33, p < 0.001). CONCLUSION Work-related access to means is a risk factor for suicide in the employed population, but is associated with a greater risk for females than males. The findings of this study suggest the importance of controlling access to lethal methods in occupations where these are readily available.

Abstract
Thoughts about suicide are a risk factor for suicide deaths and attempts and are associated with a range of mental health outcomes. While there is considerable knowledge about risk factors for suicide ideation, there is little known about protective factors. The current study sought to understand the role of perceived mattering to others as a protective factor for suicide in a working sample of Australians using a cross-sectional research design. Logistic regression analysis indicated that people with a higher perception that they mattered had lower odds of suicide ideation than those with lower reported mattering, after controlling for psychological distress, demographic and relationship variables. These results indicate the importance of further research and intervention studies on mattering as a lever for reducing suicidality. Understanding more about protective factors for suicide ideation is important as this may prevent future adverse mental health and behavioural outcomes.

Abstract
Introduction A Job Exposure Matrix (JEM) for psychosocial job stressors allows assessment of these exposures at a population level. JEMs are particularly useful in situations when information on psychosocial job stressors were not collected individually and can help eliminate the biases that may be present in individual self-report accounts. This research paper describes the development of a JEM in the Australian context. Methods The Household Income Labour Dynamics in Australia (HILDA) survey was used to construct a JEM for job control, job demands and complexity, job insecurity, and fairness of pay. Population median values of these variables for all employed people (n = 20,428) were used to define individual exposures across the period 2001 to 2012. The JEM was calculated for the Australian and New Zealand Standard Classification of Occupations (ANZSCO) at the four-digit level, which represents 358 occupations. Both continuous and binary exposures to job stressors were calculated at the 4-digit level. We assessed concordance between the JEM-assigned and individually-reported exposures using the Kappa statistic, sensitivity and specificity assessments. We conducted regression analysis using mental health as an outcome measure. Results Kappa statistics indicate good agreement between individually-reported and JEM-assigned dichotomous measures for job demands and control, and moderate agreement for job insecurity and fairness of pay. Job control, job demands and security had the highest sensitivity, while specificity was relatively high for the four exposures. Regression analysis shows that most individually reported and JEM measures were significantly associated with mental health, and individually-reported exposures produced much stronger effects on mental health than the JEM-assigned exposures. Discussion These JEM-based estimates of stressors exposure provide a conservative proxy for individual-level data, and can be applied to a range of health and organisational outcomes.

Abstract
BACKGROUND People with disabilities have difficulties in obtaining work. However, evidence suggests that those with disabilities derive substantial mental health benefits from employment. This paper assesses how the relationship between work and mental health is influenced by psychosocial job quality for people working with a disability. METHODS The study design was a longitudinal cohort with 13 annual waves of data collection, yielding a sample of 122,883 observations from 21,848 people. Fixed-effects within-person regression was used to control for time invariant confounding. The Mental Component Summary (MCS) of the Short Form 36 (SF-36) measure was used as the primary outcome measure. The main exposure was a six-category measure of psychosocial job quality and employment status (including 'not in the labour force' [NILF] and unemployment). Disability status ('no waves of disability reported' and 'all contributed waves with reported disability') was assessed as an effect modifier. We also conducted a secondary analysis on respondents contributing both disability and non-disability waves. RESULTS For those with no disability, the greatest difference in mental health (compared to optimal employment) occurs when people have the poorest quality jobs (-2.12, 95% CI -2.48, -1.75, p < 0.001). The relative difference in mental health was less in relation to NILF and unemployment (-0.39 and -0.66 respectively). For those with consistent disability, the difference in mental health when employed in an optimal job was similar between the poorest quality jobs (-2.25, 95% CI -3.84, -0.65, p = 0.006), NILF (-2.84, 95% CI -4.49, -1.20, p = 0.001) or unemployment (-2.56, 95% CI -4.32, -0.80, p = 0.004). These results were confirmed by the secondary analysis. CONCLUSIONS Efforts to improve psychosocial job quality may have significant mental health benefits for people with disabilities. This will contribute to the economic viability of disability employment insurance schemes in Australia and other high-income countries.

Abstract
BACKGROUND Unemployment and economic inactivity are associated with worse mental health in the general population, but there is limited understanding of whether these relationships are different for those persons with mental or physical disabilities. The aim of this study was to assess whether there were differences in mental health by labour force status among persons with and without disabilities. METHOD Over eight annual waves of the Household, Income and Labour Dynamics in Australia (HILDA) survey, a total of 2379 people with disabilities and 11 417 people without disabilities were identified. Mental health using the Mental Component Summary (MCS) from the Short Form 36 was modelled as a function of labour force status using fixed-effects regression models to control for time invariant confounding. Differences between those with and without disabilities were assessed by including an interaction term in regression models. RESULTS After finding evidence of effect modification, regression models were stratified by disability status. After adjustment, unemployment and economic inactivity were associated with a -1.85 (95% CI -2.96 to -0.73, p=0.001) and -2.66 (95% CI -3.46 to -1.86, p<0.001) reduction in scores of the MCS among those with a disability. For those without a disability, there were smaller declines associated with unemployment (-0.57, 95% CI -1.02 to -0.12, p=0.013) and economic inactivity (-0.34, 95% CI -0.64 to 0.05, p=0.022). CONCLUSIONS These results suggest a greater reduction in mental health for those persons with disabilities who were unemployed or economically inactive than those who were employed. This highlights the value of employment for people with disabilities.

Abstract
BACKGROUND There are ongoing questions about whether unemployment has causal effects on suicide as this relationship may be confounded by past experiences of mental illness. The present review quantified the effects of adjustment for mental health on the relationship between unemployment and suicide. Findings were used to develop and interpret likely causal models of unemployment, mental health and suicide. METHOD A random-effects meta-analysis was conducted on five population-based cohort studies where temporal relationships could be clearly ascertained. RESULTS Results of the meta-analysis showed that unemployment was associated with a significantly higher relative risk (RR) of suicide before adjustment for prior mental health [RR 1.58, 95% confidence interval (CI) 1.33-1.83]. After controlling for mental health, the RR of suicide following unemployment was reduced by approximately 37% (RR 1.15, 95% CI 1.00-1.30). Greater exposure to unemployment was associated with higher RR of suicide, and the pooled RR was higher for males than for females. CONCLUSIONS Plausible interpretations of likely pathways between unemployment and suicide are complex and difficult to validate given the poor delineation of associations over time and analytic rationale for confounder adjustment evident in the revised literature. Future research would be strengthened by explicit articulation of temporal relationships and causal assumptions. This would be complemented by longitudinal study designs suitable to assess potential confounders, mediators and effect modifiers influencing the relationship between unemployment and suicide.

Abstract
OBJECTIVES To investigate the 'adaptation' versus 'sensitisation' hypotheses in relation to mental health and labour market transitions out of employment to determine whether mental health stabilised (adaptation) or worsened (sensitisation) as people experienced one or more periods without work. METHODS The Household Income and Labour Dynamics of Australia (HILDA) longitudinal survey was used to investigate the relationship between the number of times a person had been unemployed or had periods out of the labour force (ie, spells without work) and the Mental Component Summary (MCS) of the Short Form 36 (SF-36). Demographic, health and employment related confounders were included in a series of multilevel regression models. RESULTS During 2001-2010, 3362 people shifted into unemployment and 1105 shifted from employment to not in the labour force. Compared with participants who did not shift, there was a 1.64-point decline (95% CI -2.05 to -1.23, p<0.001) in scores of the MCS SF-36 among those who had one spell of unemployment (excluding not in the labour force), and a 2.56-point decline (95% CI -3.93 to -1.19, p<0.001) among those who had two or more spells of unemployment after adjusting for other variables. Findings for shifts from employment to 'not in the labour force' were in the same direction; however, effect sizes were smaller. CONCLUSIONS These results indicate that multiple spells of unemployment are associated with continued, though small, declines in mental health. Those who leave employment for reasons other than unemployment experience a smaller reduction in mental health.

Abstract
Background: The World Health Organization (WHO) study entitled Suicide Trends in At-Risk Territories (START) is an international multisite initiative that aims to stimulate suicide research and prevention across different areas of the globe. A central component of the study is the development of registration systems for fatal and nonfatal suicidal behaviors. Aims: This paper provides an overview of the data collected on suicidal behaviors from the participating locations in the START study. Method: Descriptive statistics on the data are presented in terms of age, sex, and method. Results: A greater proportion of suicide deaths occurred among males. In all areas except the Philippines more females than males engaged in nonfatal suicidal behaviors. Compared to Australia, Italy, New Zealand, the Philippines, and Hong Kong SAR, in the Pacific Islands suicide most often occurs in younger age groups. Results indicate notable variations between countries in choice of method. A greater proportion of suicides occurred by hanging in Pacific Islands, while inhalation of carbon monoxide, use of firearms, ingestion of chemicals and poisons, and drug overdose were the most frequent methods of choice in other areas. Conclusion: The information drawn from this study demonstrates the enormous variation in suicidal behavior across the areas involved in the START Study. Further research is needed to assess the reliability of the established data-recording systems for suicidal behaviors. The baseline data established in START may allow the development of suicide prevention initiatives sensitive to variation in the profile of suicide across different locations.

Abstract
OBJECTIVE Around the world, a substantial proportion of motor vehicle crash deaths are recognized as "hidden" suicides. This project sought to progress understandings of drivers who used a motor vehicle to die by suicide in Queensland, Australia, during the period 1990 to 2007. METHODS Data for this study were derived from the Queensland Suicide Register and forensic crash investigation case records. Analysis focused on life circumstances and events preceding the death, physical and mental illnesses, past suicidality, and indication of suicide intent (e.g., suicide notes or statements). RESULTS Compared to cases using other methods, confirmed driver suicides were more likely to be males aged between 25 and 44 years who were employed at the time of death. A large proportion of driver suicides had consumed alcohol immediately prior to the crash and experienced a number of life events, including relationship conflict, legal or criminal issues, and financial problems. CONCLUSION These exploratory results indicate the need to educate crash investigators about the characteristics of those who use a motor vehicle to die. Improving the information available on the mental and physical health and background life-related factors of crash victims can help coroners and researchers determine whether these deaths were intentional. Further investigation is needed in order to formulate intervention strategies for those who may be vulnerable to driver suicide.

Abstract
2523 Background: BSA-based cytotoxic dosing does not account for the individual variability in drug disposition. In the case of D, CYP 3A4 probes such as the EBT have been assessed to individualise dosing, but inconsistently. This report is the first study comparing the EBT directly with the widely available general P450 probe, the ACL test, for the prediction of D PK when given either q 21 days or weekly. Methods: Patients (pts) with pre-treated advanced malignancy suitable for D therapy, Se bilirubin≤1.0xUNL, AST≤1.5xUNL & ALP≤2.5xUNL, were entered. Prior to D therapy, pts underwent EBT and ACL test. Pts were given IV 14C N-methyl-erythromycin and exhaled breath samples were captured for 14CO2 from 5–120 mins post. The EBT parameters determined: 14CO2 flux at 10 min (CO2f10), & 20 min (CO2f20), (iii) terminal rate constant kCO2 (iv) AUCCO2,(0-∞) & AUCCO2,(0–60). For the ACL test, pts was given oral antipyrine 10mg/kg, blood samples were collected from 0, 4 & 24 hrs post, and serum levels measured: ACL was calculated as per Farrell et al.(Br J Clin Pharmacol 18:559). D was given 75mg/m2 q21 days or 35mg/m2 weekly. Samples taken for D PK in course 1 day 1, parameters included: half life (tD1/2), & clearance (CLD). Correlations were sought between EBT parameters, ACL values and D PK parameters. Results: 20 pts accrued, M:F= 12:8, Median age= 65. Mean BSA = 1.77m2 (1.44–2.07). D q21 days:D weekly= 13:7. EBT parameters (N= 19) (Mean, [CV%]): CO2f10 (%/min) 0.051 (106), CO2f20 0.052 (82), kCO2 (min- 1) 0.007 (22), AUCCO2,(0-∞) 7.9 (85), AUCCO2,(0–60) 2.64 (81). ACL (N=19) (ml/min); 35.8 (37). No significant differences observed for EBT parameters and ACL between the q21 days vs weekly dosing. D PK parameters (N=19): CLD (l/hr) 57.2 (36), tD1/2 (hrs) 12.7 (33). No correlations were observed between the D PK and EMBT parameters for all pts and regardless of the regimen given. For D weekly pts, a significant linear relationship was observed between CLD and ACL (P =0.007, R2= 79.47%). Conclusions: The utility of EBT for the prediction of D PK was not confirmed in this study. The Antipyrine Clearance test may be superior in this regard for D, but regimen dependent and hence warrants further evaluation. No significant financial relationships to disclose.
