Comparison of the characteristics of suicide attempters with major depressive disorder and those with no psychiatric diagnosis in emergency departments of general hospitals in China

Stigma and Chronic Pain

Stigma is defined by the World Health Organization (WHO) as "a mark of shame, disgrace or disapproval that results in an individual being rejected, discriminated against and excluded from participating in a number of different areas of society". Extensive literature searches have documented stigma in the context of health. Among the physical health conditions that are associated with stigma, chronic pain deserves particular attention. Stigma experienced by individuals with chronic pain affects their entire life. Literature identifies multiple dimensions or types of stigma, including public stigma, structural stigma and internalized stigma. Recent literature supports the biopsychosocial model of pain, according to which biological, psychological and sociocultural variables interact in a dynamic manner to shape an individual's response to chronic pain. Chronic pain affects a higher proportion of women than men around the world. There is an inadequate education of health care professionals regarding pain assessment and their insecurity to manage patients with chronic pain. A first-line intervention strategy could be to promote pain education and to expand knowledge and assessment of chronic pain, as recently highlighted for headache disorders, paradigmatically for resistant or refractory migraine, whose diagnosis, without an adequate education to understand the possible fluctuations of the disease, may have profound psychological implications with the idea of insolvability and contribute to stigmatizing the patient.

Suicidal Risks in 12 DSM-5 Psychiatric Disorders

OBJECTIVE

As modern studies evaluating suicidal behaviors in large samples of major psychiatric disorder patients are rare, we compared suicidal risks associated with a variety of psychiatric diagnoses.

METHODS

We quantified rates of intake suicidal ideation and lifetime attempts, suicides, and violent acts (attempts + suicides) in 6050 adult patients in a European psychiatric center, diagnosed with 12 prevalent, DSM-5 psychiatric disorders.

RESULTS

Ideation ranged from 53.9% of subjects with bipolar disorder (BD) with mixed features, to 8.70% in anxiety disorders. Subjects making at least one suicide attempt were most prevalent in BD with mixed or psychotic features. Suicide rates ranked: substance abuse > BD with psychotic features > psychotic disorders ≥ BD-I > major depressive disorder (MDD). Suicidal intensity (acts/100 PEY) was highest with BD, psychotic disorders, and MDD; lethality (lower attempt/suicide ratio) was greatest with substance abuse, psychotic disorders, and BD with psychotic features. Rates of suicidal acts in BD vs. MDD were similarly high among ever-hospitalized subjects but much lower in never-hospitalized MDD subjects. Women had higher overall risks of ideation and attempts, but violent acts and suicide were more likely among men, whereas SMR for suicide was greater among women, presumably reflecting very low risks among women in the regional general population.

CONCLUSIONS

Suicidal risks were particularly high in BD with psychotic or mixed features as well as with substance abuse and in severe MDD with hospitalization.

Prevalence and related factors of suicide attempts in first-episode and untreated Chinese Han outpatients with psychotic major depression

BACKGROUND

Major depressive depression (MDD) is often accompanied by suicidal behavior. Increasing evidence shows that MDD patients display psychotic symptoms. However, the relationship between psychotic symptoms and suicide attempt in MDD has not been reported. Therefore, this study was to identify the prevalence and associated factors of suicide attempts in first-episode and untreated Chinese Han outpatients comorbid with psychotic major depression (PMD).

METHODS

1718 first-episode and untreated MDD outpatients were assessed with Positive Symptom Scale of Positive and Negative Syndrome Scale (PANSS), the 17-item Hamilton Depression Scale, Hamilton Anxiety Scale, and clinical global impression of severity scale (CGI-S). Some glycolipid metabolism and thyroid hormone parameters were measured.

RESULTS

In MDD patients, the percentage of PMD was 10.0%. The incidence of attempted suicide in PMD patients was 51.5%, which was more than 3 times higher than that in non-PMD patients (16.7%). In PMD patients, compared to non-attempters, suicide attempters were older, had a longer course of disease, scored higher on all scales, as well as had higher levels of thyroid stimulating hormone (TSH), thyroid peroxidases antibody, anti-thyroglobulin and blood glucose. PANSS positive symptom, CGI, diastolic blood pressure and TSH were independently associated with suicide attempts of PMD.

CONCLUSIONS

PMD patients have a higher prevalence of suicide attempt than non-PMD patients. Some demographic and clinical parameters are relevant factors for suicide attempt in PMD patients.

Prevalence of suicide attempt in individuals with major depressive disorder: a meta-analysis of observational surveys

BACKGROUND

Suicide attempt (SA), which is one of the strongest predictors of completed suicide, is common in major depressive disorder (MDD) but its prevalence across epidemiological studies has been mixed. The aim of this comprehensive meta-analysis was to examine the pooled prevalence of SA in individuals with MDD.

METHODS

A systematic literature search was conducted in PubMed, Embase, PsycINFO, Web of Science and Cochrane Library from their commencement date until 27 December 2017. Original studies containing data on prevalence of SA in individuals with MDD were analyzed.

RESULTS

In all, 65 studies with a total of 27 340 individuals with MDD were included. Using the random effects model, the pooled lifetime prevalence of SA was 31% [95% confidence interval (CI) 27-34%], 1-year prevalence was 8% (95% CI 3-14%) and 1-month prevalence was 24% (95% CI 15-34%). Subgroup analyses revealed that the lifetime prevalence of SA was significantly associated with the patient setting, study region and income level, while the 1-month prevalence of SA was associated with only the patient setting.

CONCLUSION

This meta-analysis confirmed that SA was common in individuals with MDD across the world. Careful screening and appropriate interventions should be implemented for SA in the MDD population.
