Clinical Markers Associated With Risk of Suicide or Drug Overdose Among Individuals With Smoking Exposure: A Longitudinal Follow-up Study of the COPDGene Cohort. Chest 2023; 163:292-302. [PMID: 36167120 PMCID: PMC10083129 DOI: 10.1016/j.chest.2022.09.022] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Revised: 08/11/2022] [Accepted: 09/03/2022] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND Studies have shown that COPD and smoking are associated with increased suicide risk. To date, there are no prospective studies examining suicide risk among individuals with smoking exposure along a spectrum of pulmonary diseases ranging from normal spirometry to severe COPD. RESEARCH QUESTION Which clinical variables predict death by suicide or overdose of indeterminate intent in a large cohort of individuals with smoking exposure within the Genetic Epidemiology of COPD (COPDGene) study? STUDY DESIGN AND METHODS We studied data from 9,930 participants involved in COPDGene, a multisite, prospective cohort study of individuals with smoking exposure. Primary cause of adjudicated deaths was identified by using death certificates, family reports, and medical records. Time to death by suicide/overdose was examined as the primary outcome in Cox regression models including age, sex, race, BMI, pack-years, current smoking status, airflow limitation (FEV1 % predicted), dyspnea (modified Medical Research Council scale score ≥ 2), 6-min walk distance, supplemental oxygen use, and severe exacerbations in the prior year with time-varying covariates and other causes of death as a competing risk. RESULTS The cohort was 47% female and 33% Black (67% White); they had a mean ± SD age of 59.6 ± 9.0 years and a mean FEV1 % predicted of 76.1 ± 25.5. Sixty-three individuals died by suicide/overdose. Factors associated with risk of suicide/overdose were current smoking (hazard ratio [HR], 6.44; 95% CI, 2.64-15.67), use of sedative/hypnotics (HR, 2.33; 95% CI, 1.24-4.38), and dyspnea (HR, 2.23; 95% CI, 1.34-3.70). Lower risk was associated with older age (per-decade HR, 0.45; 95% CI, 0.31-0.67), higher BMI (HR, 0.95; 95% CI, 0.91-0.99), and African-American race (HR, 0.41; 95% CI, 0.23-0.74). Severity of airflow limitation (FEV % predicted) was not associated with suicide risk. INTERPRETATION In this well-characterized cohort of individuals with smoking exposure with and without COPD, risk factors for suicide/overdose were identified that emphasize the subjective experience of illness over objective assessments of lung function.

Midlife suicide: A systematic review and meta-analysis of socioeconomic, psychiatric and physical health risk factors. J Psychiatr Res 2022; 154:233-241. [PMID: 35961179 DOI: 10.1016/j.jpsychires.2022.07.037] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2021] [Revised: 07/09/2022] [Accepted: 07/20/2022] [Indexed: 10/16/2022]
Abstract
Suicide is an increasing contributing cause of mortality in middle-aged adults; however, knowledge to guide prevention is limited. This first systematic review and meta-analysis of studies on midlife suicide has provided an overview of published research on this issue and synthesized the evidence on socioeconomic and physical and mental health factors associated with this mortality. Using PRISMA guidelines MEDLINE, Embase, PsycINFO, Scopus and Web of Science were searched for English-language publications that involved persons aged 35 to 65, used individual-level data, and reported prevalence of exposure(s) or relative risks. The search identified 62 studies on midlife suicides and associated factors (28 for SES, 22 for psychiatric disorder and 23 for physical illness). All studies were from high income countries, and most (80.6%) used data from population registries. Meta-analyses showed that the pooled prevalence of exposure in suicide decedents was 57.8% for psychiatric disorder, 56.3% for low income, 43.2% for unemployment, and 27.3% for physical illness. The associated pooled risk ratio was 11.68 (95% confidence intervals: 5.82-23.47) for psychiatric illness of any type, 12.59 (8.29-19.12) for mood disorders, 3.91 (2.72-5.59) for unemployment, 3.18 (2.72-3.72) for being separated or divorced, 2.64 (2.26-3.10) for cancer, 2.50 (0.96-6.38) for central nervous system illness, and 2.26 (1.16-4.41) for low income. In conclusion, midlife suicide is strongly associated with socioeconomic difficulties and physical and psychiatric illnesses that are common in this age population. Future investigations should consider the interactions between risk factors, the intersectionality of sex and ethnicity, and include data from low- and middle-income countries.

Abstract
We aimed to examine the prevalence of suicidal ideation in patients with chronic obstructive pulmonary disease (COPD) and the association between demographic and clinical variables and the occurrence of suicidal thoughts. This was a cross-sectional study. Sociodemographic and clinical data were recorded, and questionnaires were used to assess depressive symptoms (Beck Depression Inventory), comorbidities (Charlson Index), cognitive performance (Mini Mental State Examination), and quality of life (EuroQoL-5 dimensions and CAT). Specific questions about suicide-related behavior were included. Multivariate logistic regression analysis identified the significant factors associated with previous suicidal ideation and suicide attempts. The analysis included 1190 subjects. The prevalence of suicidal ideation and suicide attempts were 12.1% and 2.5%, respectively. Severely depressed patients had the highest prevalence of suicide-related behavior. The adjusted logistic model identified factors significantly associated with suicidal ideation: sex (odds ratio (OR) for women vs. men = 2.722 (95% confidence interval (CI) = 1.771-4.183)), depression score (OR = 1.163 (95% IC = 1.127-1.200)), and Charlson Index (OR 1.228 (95% IC 1.082-1.394)). Suicidal ideation is common in COPD patients, especially in women. While addressing suicidal ideation and suicide prevention, clinicians should first consider the management of depressive symptomatology and the improvement of coping strategies.

Abstract
BACKGROUND Patients living with chronic obstructive pulmonary disease (COPD) commonly present several limitations in their daily activities, high depression rates, and low quality of life, which makes this population a risk group for suicide. This study aims to systematically assess the literature on the association between CPOD and the likelihood of suicide. METHODS The protocol was registered in PROSPERO (CRD42018096618). The Latin-American and Caribbean Health Sciences Literature (LILACS), PubMed, SciELO, Scopus, LIVIVO, Web of Science, and PsychNET databases were used as primary study sources. OpenThesis and OpenGrey were used to partially capture the "grey literature". A manual search was also performed through a systematized analysis of the references of eligible articles. The risk of bias among the studies included was assessed with the Joanna Briggs Institute Critical Appraisal Tools for Systematic Reviews. A random effects meta-analysis was performed to estimate the variation in odds ratio (OR) and 95% confidence intervals (95% CI). RESULTS The search provided 4762 results, from which only seven met the eligibility criteria and were ultimately included in the qualitative assessment of the review. The studies were published from 2002 to 2015. All studies presented low risk of bias. The total sample included 1390 suicide cases of COPD patients. The meta-analysis, which was based on five eligible case control studies, found that people with history of COPD are more likely to commit suicide (OR = 1.90; 95% CI = 1.27-2.48; p = 0.002). CONCLUSION COPD patients are 1.9 times more likely to commit suicide than people without COPD.

Hypoxia-related risk factors for death by suicide in a national clinical sample. Psychiatry Res 2019; 273:247-251.

Abstract
The relationship between three markers of chronic hypoxia (altitude, smoking and chronic obstructive pulmonary disease (COPD)) and suicide risk has not been well-studied. We conducted a population-based cohort study evaluating the association between chronic hypoxia and suicide risk. Patients entered the cohort in their first year with a documented healthcare encounter and remained in the cohort until their death or the end of the study period. Generalized estimating equation (GEE) methodology was used to assess the association between suicide and three risk markers of chronic hypoxia. Findings were summarized using odds ratio (OR) and 95% confidence intervals (CI). Among the 9,620,944 patients in the cohort, there were 22,403 suicide deaths. There was a statistically significant progression of suicide risk as altitude rose in increments of 1000 m (OR: 1.22). There was a strong association between the number of hypoxic conditions and the odds of suicide. Patients with three markers of chronic hypoxia was nearly four times more likely to die by suicide than patients with no markers (OR: 3.96). Chronic hypoxia is a risk factor for suicide and having multiple indicators of hypoxia confers a greater risk for suicide, indicating a dose-response relationship.

Abstract
OBJECTIVE The association between abortion and postmenopausal mental health has not been clearly established in Asian women. The objective of this study was to evaluate the effect of abortion experiences on suicidal ideation and mental health in Korean postmenopausal women. MATERIALS AND METHODS This study included 5133 postmenopausal women registered in the Korean National Health and Nutrition Examination Survey between 2010 and 2012. Difference in suicidal ideation according to type and number of abortions was analyzed. We used survey multiple logistic regression analysis to evaluate the effect of abortion experiences on the risk for suicidal ideation expressed as adjusted odd ratios (ORs) with 95% confidence intervals (95%CIs). RESULTS The risk of suicidal ideation was significantly higher in women who experienced more than three abortions (27.9%). While the incidence of suicidal ideation was not significantly affected by the number of spontaneous abortions (p = 0.718), suicidal ideation was significantly more frequent in women who had undergone ≥ three abortions (p = 0.003). After adjusting for demographic confounding factors, women who underwent ≥ three induced abortions had higher risk for suicidal ideation (OR: 1.510; 95% CI: 1.189-1.919; p = 0.031). This risk remained elevated even after controlling for depression (OR: 1.391; 95% CI: 1.1086-1.871, p = 0.002). Moreover, the risk of experiencing a depressive mood in daily life was also increased with increasing number of induced abortions even after controlling for depression (OR: 1.657; 95% CI: 1.274-2.156, p = 0.002). CONCLUSION Undergoing three or more induced abortions during reproductive age was associated with postmenopausal suicidal ideation, stress, and depression. However, such association was not noted in those with spontaneous abortion, even in women with more miscarriages. Thus, clinicians should evaluate depression and suicidal ideation in women with multiple induced abortions.

Abstract
PURPOSE The aim of this paper is to investigate the association between suicide and Lyme and associated diseases (LAD). No journal article has previously performed a comprehensive assessment of this subject. INTRODUCTION Multiple case reports and other references demonstrate a causal association between suicidal risk and LAD. Suicide risk is greater in outdoor workers and veterans, both with greater LAD exposure. Multiple studies demonstrate many infections and the associated proinflammatory cytokines, inflammatory-mediated metabolic changes, and quinolinic acid and glutamate changes alter neural circuits which increase suicidality. A similar pathophysiology occurs in LAD. METHOD A retrospective chart review and epidemiological calculations were performed. RESULTS LAD contributed to suicidality, and sometimes homicidality, in individuals who were not suicidal before infection. A higher level of risk to self and others is associated with multiple symptoms developing after acquiring LAD, in particular, explosive anger, intrusive images, sudden mood swings, paranoia, dissociative episodes, hallucinations, disinhibition, panic disorder, rapid cycling bipolar, depersonalization, social anxiety disorder, substance abuse, hypervigilance, generalized anxiety disorder, genital-urinary symptoms, chronic pain, anhedonia, depression, low frustration tolerance, and posttraumatic stress disorder. Negative attitudes about LAD from family, friends, doctors, and the health care system may also contribute to suicide risk. By indirect calculations, it is estimated there are possibly over 1,200 LAD suicides in the US per year. CONCLUSION Suicidality seen in LAD contributes to causing a significant number of previously unexplained suicides and is associated with immune-mediated and metabolic changes resulting in psychiatric and other symptoms which are possibly intensified by negative attitudes about LAD from others. Some LAD suicides are associated with being overwhelmed by multiple debilitating symptoms, and others are impulsive, bizarre, and unpredictable. Greater understanding and a direct method of acquiring LAD suicide statistics is needed. It is suggested that medical examiners, the Centers for Disease Control and Prevention, and other epidemiological organizations proactively evaluate the association between LAD and suicide.

Abstract
BACKGROUND Many somatic disorders are complicated by depression and increase the risk of suicide. Little is known about whether antidepressants might reduce the suicidal risk in patients with somatic disorders. METHODS Data on diagnoses and antidepressant prescriptions were derived from the Social and Health Information System of the Friuli Venezia Giulia Region. Cases were all suicides that occurred in the region during the years 2003-2013 and were sex- and age-matched to controls from the general population. Conditional logistic regression analysis was used to assess the association between suicide and somatic disorders. RESULTS The suicide rate in Friuli Venezia Giulia decreased from 11.3 to 10.7 per 100,000 inhabitants during the years 2003-2013, however patients with somatic disorder had a three times increased risk of suicide. Elderly somatic patients' suicide risk was twice as high as younger patients. The risk increased from 2.6 to 9.8 times as the number of comorbid disorders increased from 1 to 4 and over. Although no significant risk of suicide in patients with somatic disorders was found when patients were adherent to antidepressants, only 11.5% of the suicides was adherent in the year prior to death. CONCLUSIONS Medical illnesses and underlying depressive symptoms may have a synergy effect on the risk of suicide, particularly in older patients and in patients with multiple morbidities. Since medically ill subjects adherent to antidepressants did not show a significant risk of suicide, early identification and adequate treatment of depression in somatic patients should be considered in order to prevent suicide.
