Anti-suicide effect of lithium at infratherapeutic dose, a case report

An anti-suicide effect has been well documented in prolonged lithium treatments, with high-quality evidence in bipolar disorder and unipolar depression, shown to be significantly superior to other mood stabilizers, with a 50-80% of reduction in suicide risk.

Role of thwarted belongingness, perceived burdensomeness and psychological distress in the association between adverse childhood experiences and suicidal ideation in college students

BACKGROUND

Adverse childhood experiences (ACEs) have a detrimental impact on short- and long-term mental and physical health. A growing body of research has indicated that the prevalence of suicidal phenomena is significantly higher among individuals with a history of ACEs. However, there is a lack of understanding about processes that result in ACEs leading to suicidal ideation when testing within a theoretical framework.

AIMS

To develop and test a multidimensional model that would explain the association between ACEs and suicidal ideation in college students.

METHOD

Data were obtained from a cross-sectional survey completed by 321 college students primarily recruited from universities in Ireland. Participants were aged 18-21 (n = 176) and 22-25 years (n = 145). An ACEs questionnaire, the Interpersonal Needs Questionnaire, which assessed thwarted belongingness and perceived burdensomeness, the CORE-10, which assessed psychological distress, and the Suicide Ideation Scale (SIS) were administered.

RESULTS

After controlling for gender and sexual orientation, results revealed a significant direct effect of ACEs on suicidal ideation such that more accumulated ACEs were associated with higher suicidal ideation (effect size 0.30; 95% CI 0.047-0.538). A significant indirect effect of ACEs on suicidal ideation through perceived burdensomeness and psychological distress, and thwarted belongingness and psychological distress, was observed (effect size 0.90; 95% CI 0.558-1.270).

CONCLUSIONS

Findings suggest that ACEs have a detrimental impact on college students' mental health. Results highlight the potential benefits of ACE-informed interventions that target thwarted belongingness and perceived burdensomeness to countervail suicidal ideation in college students.

Suicide by Inhalation of Carbon Monoxide of Car Exhausts Fumes

BACKGROUND

Carbon monoxide (CO) is a major and ubiquitous component of fire atmospheres produced when organic matter is burned in an inadequate supply of oxygen. Accidental poisoning by CO is common in cold climates where fireplaces, a gas, electric or kerosene heaters or grills are used inside ill-ventilated buildings. In the Brazilian Amazon, with its hot and humid climate, there is no need for the use of heaters and accidents may occur in cases of residential fires or burning of the forests for land use in agriculture.

OBJECTIVE

We present a case of CO suicide of twenty-six-year-old men.

METHODS

A forensic autopsy was performed to evaluate the circumstances, cause and medio-legal death etiology.

RESULTS

Autopsy evidenced the typical but also not commonly published cherry-red color of the hypostasis, lungs and other organs, and the very fluid cherry-red blood. The cause of death was due to a massive CO inhalation.

CONCLUSION

While these poisonings are well recognized, and a vast number of publications on CO toxicity exist, both in an environmental and industrial context, suicide is infrequently encountered in forensic practice and the typical signs are rarely seen in the literature.

Late-life suicide in Asian people living in New Zealand: a qualitative study of coronial records

BACKGROUND

There has been no previous study examining the phenomenon of suicide in older Asians in New Zealand. The aim of this study was to identify common factors and gain a better understanding of late-life suicide in Asian people living in New Zealand.

METHODS

New Zealand Coronial Services provided records of all closed cases of late-life suicides (age ≥ 65 years) between July 2007 and December 2012. Out of the total of 225 cases, 15 were recorded as being of Asian ethnicity. These cases were reviewed in their entirety using a qualitative thematic analysis approach.

RESULTS

Eight Asian men and seven Asian women completed suicide during this period. The majority (93%) lived with their families, and 80% were found by family after having completed suicide at home. Three main themes emerged from the thematic analysis: (i) suicide occurring in the context of a family; (ii) declining physical health; and (iii) a violent method of suicide. The role of the family has not been previously identified in other studies of late-life suicide in New Zealand.

CONCLUSIONS

Further research is needed to identify ways Asian families can access culturally appropriate and accessible support and mental health services for their older members at risk of suicide. There is also a need for developing post-suicide interventions specifically for Asian families. The findings of this study have added to the growing evidence of declining physical health acting as a drive for late-life suicide.

Mortality in depressed and non-depressed primary care Swedish patients: a 12-year follow-up cohort study

BACKGROUND

Data regarding mortality among depressed patients in Swedish primary care is limited.

OBJECTIVES

We compared mortality in a cohort of depressed and non-depressed patients at long-term follow-up and compared these values with standardized mortality rates (SMRs) in the Swedish population. Hazards ratios (HRs) for the relationship between death and depression, psychosocial factors and lifestyle were analysed, and we explored the proportion of unnatural causes of deaths.

METHODS

Mortality was studied in a cohort of 124 depressed and 280 non-depressed patients 12 years after being diagnosed with depression in primary care. Mortality and the mortality rates and SMRs in depressed and non-depressed patients were compared by gender. Cox regression was applied to calculate HRs for the risk of dying for explanatory variables, including depression, psychosocial factors and lifestyle.

RESULTS

A larger number of depressed patients, 11% (n = 14), compared with non-depressed patients, 4% (n = 12), died (P = 0.008), with significantly higher values among depressed men (P = 0.014). SMRs did not differ from those of the Swedish population. Depression was the only variable associated with a significantly elevated risk of death (HR, 3.34; 95% CI, 1.38-8.08). Nearly one-third of deaths had unnatural causes when alcohol-related deaths were included.

CONCLUSION

This study underlines the importance of careful follow-up of all depressed patients' mental and physical health and the intervention on unhealthy lifestyles. Large primary care database studies are needed to explore the association between depression, co-morbid somatic diseases, lifestyle and mortality.

Suicidal behaviour on subway systems: a review of the epidemiology

Suicide on subway systems is a public health challenge that has been reported in urban centers worldwide. Our objective was to analyze studies of suicide on subway systems, develop a profile of characteristics that are suggestive of association with suicides or attempts, and show how this profile can inform prevention. A literature review involving epidemiology studies and studies relating to subway suicide was conducted. Twenty-eight studies were included in this review. Across studies, characteristics were not often assessed for risk factor status, although several characteristics were remarkably similar. Those attempting suicide on the subway appear to be affected by serious mental illness and have contact with mental health services before the suicidal behavior. Several characteristics may be shared among this population, emphasizing the potential for prevention in clinical and public health domains. Well-designed studies that utilize robust data collection and statistical methods are needed to establish the risk status associated with these characteristics.
