Risk factors for suicide reattempt: a systematic review and meta-analysis.

BACKGROUND: Suicide is one of the main external causes of death worldwide. People who have already attempted suicide are at high risk of new suicidal behavior. However, there is a lack of information on the risk factors that facilitate the appearance of reattempts. The aim of this study was to calculate the risk of suicide reattempt in the presence of suicidal history and psychosocial risk factors and to estimate the effect of each individual risk factor. METHODS: This systematic review and meta-analysis were conducted following the PRISMA-2020 guidelines. Studies on suicide reattempt that measured risk factors were searched from inception to 2022. The risk factors studied were those directly related to suicide history: history of suicide prior to the index attempt, and those that mediate the transition from suicidal ideation to attempt (alcohol or drug misuse, impulsivity, trauma, and non-suicidal self-injury). RESULTS: The initial search resulted in 11 905 articles. Of these, 34 articles were selected for this meta-analysis, jointly presenting 52 different effect sizes. The pooled effect size across the risk factors was significant (OR 2.16). Reattempt risk may be increased in presence of any of the following risk factors: previous history, active suicidal ideation, trauma, alcohol misuse, and drug misuse. However, impulsivity, and non-suicidal self-injury did not show a significant effect on reattempt. CONCLUSION: Most of the risk factors traditionally associated with suicide are also relevant when talking about suicide reattempts. Knowing the traits that define reattempters can help develop better preventive and intervention plans.

Suicide mortality in Spain during the COVID-19 pandemic: Longitudinal analysis of sociodemographic factors.

The COVID-19 pandemic has compromised public health response across the globe. Several countries reported increasing number of suicides during the pandemic. This study aimed to analyze the suicide mortality series in Spain (2000-2021), with a particular interest in depicting longitudinal trends during the COVID-19 pandemic. Moreover, it intended to identify sociodemographic groups with a higher increase in suicide victims during the pandemic. To do so, suicide cases from the National death index data were used. Weighted annual mortality rate was compared between pre-pandemic and pandemic years. Poisson time series models were used to analyze the trend in suicide mortality, considering sociodemographic variables (sex, age, migration status, marital status, and urbanicity). As a result, weighted mortality rate for 2020 was 8.92 (CI95 = [8.29, 9.57]) and 9.21 for 2021 (CI95 = [8.56, 9.88]). Annual mortality from the pandemic years was significantly higher than mortality from the prepandemic ones (p < .01). Poisson regression revealed a significant increase of cases during the pandemic months, RR = 1.05 (CI95 = [1.02, 1.08]); being significant for both sexes, and migration groups (RR > 1.02, across series). A significantly increased number of suicides was also observed for mid-age adults, large urban areas, and single people (RR > 1.05, across series). To sum up, our study supports an increasing number of suicide victims in Spain during the pandemic. We show that the COVID-19 influence on suicide risk factors (e.g., lack of social support networks) plays a critical role in the increasing trend of specific sociodemographic groups.

Psychiatric profiles in suicidal attempters: Relationships with suicide behaviour features.

BACKGROUND: Suicide constitutes a major health concern worldwide, being a significant contributor of death, globally. The diagnosis of a mental disorder has been extensively linked to the varying forms of suicidal ideation and behaviour. The aim of our study was to identify the varying diagnostic profiles in a sample of suicide attempters. METHODS: A sample of 683 adults (71.3% females, 40.10±15.74 years) admitted at a hospital emergency department due to a suicide attempt was recruited. Latent class analysis was used to identify diagnostic profiles and logistic regression to study the relationship between comorbidity profile membership and sociodemographic and clinical variables. RESULTS: Two comorbidity profiles were identified (Class I: low comorbidity class, 71.3% of attempters; Class II: high comorbidity class, 28.7% of attempters). Class I members were featured by the diagnosis of depression and general anxiety disorder, and low comorbidity; by contrast, the high comorbidity profile was characterized by a higher probability of presenting two or more coexisting psychiatric disorders. Class II included more females, younger, with more depressive symptoms and with higher impulsivity levels. Moreover, Class II members showed more severe suicidal ideation, higher number of suicide behaviours and a greater number of previous suicide attempts (p<.01, for all the outcomes), compared to Class I members. CONCLUSIONS: Psychiatric profiles may be considered for treatment provision and personalized psychiatric treatment in suicidal attempters as well as tackle suicide risk.

Efficiency of psychological interventions in the prevention of suicidal behavior and self-injury in penitentiary population: A systematic review.

INTRODUCTION: Suicidal behavior is an important public health problem, with a high prevalence in penitentiary context. Nowadays, there is a wide variety of specific treatment programs, aimed to prevent suicidal and self-injurious behavior in incarcerated people. These programs show relative efficiency depending on the model of the psychological intervention applied. This systematic review evaluates the efficiency of suicidal and self-injurious behavior prevention programs in prisons. METHOD: Empirical studies, evaluating prevention programs for suicidal and self-injurious behavior in penitentiary context were considered for inclusion. PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) directives were followed. Studies from 1990 to 2022 were reviewed, based on the review developed by Winicov (2019) that covered the time lapse between 1990 and 2015. Articles from 2015 to 2022 were located by database research (EBSCOHost, ScienceDirect, PubMed & ProQuest). RESULTS: 44,050 potential studies were identified. Eighteen were included in this systematic review (9 studies by Winicov, 2019). 14 studies showed efficacy of intervention programs on self-injury behavior. The use of Cognitive Behavioral Therapy (CBT) reduced suicidal ideation. In addition, positive results were observed in 3 studies using third-generation therapies as an intervention. CONCLUSIONS: Suicidal and self-injurious behavior in prison shows lower levels of incidence when specific treatment programs are applied. It's crucial to increase the evaluation in relation to the implementation of new treatment models (i.e., Dialectical Behavior Therapy - DBT, Acceptance and Commitment Therapy - ACT, Mindfulness, Functional Analytic Psychotherapy - FAP) as to better orientate prevention strategies. Further research is needed in gender sensitive interventions.

Immunometabolic alterations in older adults with heightened depressive symptom trajectories: a network approach.

Objective: To analyse the patterns of relationships between depressive symptoms and immunometabolic markers across longitudinal depression status in older people. Methods: A sample of 3349 older adults (55.21% women; initial age: m = 58.44, sd = 5.21) from the English Longitudinal Study of Ageing was used. Participants were classified according to their longitudinal depression status: minimal depressive symptoms (n = 2736), depressive episode onset (n = 481), or chronic depression (n = 132). Network analysis was used to study the relationships between depression symptoms (CES-D 8 items), inflammatory (white blood cell, C-reactive protein, fibrinogen) and metabolic biomarkers (metabolic syndrome markers). Results: Network structure remained invariant across groups. The minimal symptom group had higher overall strength than both clinical groups (p < .01). Moreover, significant relationships between symptoms and markers were observed across group-specific networks. C-reactive protein and effort symptom were positively connected in the minimal symptom group but not in the other groups. Loneliness and diastolic blood pressure were positively associated only in the chronic depression group. Finally, metabolic markers were identified as central nodes in the clinical status networks. Conclusion: The network analysis constitutes a useful approach to disentangle pathophysiological relationships that may maintain mental disorders in old age.

Exploring Pathways and Obstacles to Well-Being in Victims of Terrorism: A Qualitative Approach.

On March 11, 2004, Madrid suffered one of the worst terrorist attacks in the history of Spain, leaving more than 190 dead and 2,000 injured. For years, the psychological consequences of the attacks have been studied; however, its long-term effects on symptomatology and especially on well-being remains unknown. This study aims to explore, through a qualitative approach, pathways and obstacles to the well-being of those affected directly or indirectly by the attacks of March 11 in Madrid. Two focus groups were held, one for indirect victims and one for direct victims. Subsequently, a thematic analysis of the materials obtained was carried out. More than 10 years after the attacks, most of the participants reported great difficulty in achieving well-being. Acceptance and victims' associations seemed to act as key facilitators, while symptoms, political institutions and the media were the main obstacles. Direct and indirect victims presented similar data although aspects such as guilt and family relationships played a different role in their well-being.

Perinatal, obstetric and parental risk factors for asthma in the offspring throughout childhood: a longitudinal cohort study.

OBJECTIVES: Asthma is a common chronic and burdensome disease which typically begins in childhood. The aim of this study was to assess perinatal and obstetric factors which may increase the risk of developing asthma in the offspring. METHODS: Data from five consecutive waves (n=7,073 children, from birth to 15 years old) from a nationally-representative birth cohort of people born in the United Kingdom between 2000 and 2002, the Millennium Cohort Study (MCS), were used. The Kaplan-Meier survival curve was used to graphically display the risk of developing asthma from early childhood to adolescence. The Z-based Wald test was used to prove significant covariate loading. RESULTS: Cox regression analyzing the influence of covariates on asthma development risk showed a significant likelihood ratio test, χ2(18)=899.30, p<0.01. A parent with asthma (OR=2.02, p<0.01), a younger maternal age at delivery (OR=0.98, p<0.05), and the use of assisted reproductive technology (OR=1.43, p<0.05) were associated with an increased risk of developing asthma in the offspring. CONCLUSIONS: Perinatal factors (a younger maternal age, assisted reproductive technology) and a parental factor (a parent with asthma) increased the risk for developing asthma in the offspring.

Risk of suicide attempt repetition after an index attempt: A systematic review and meta-analysis.

OBJECTIVES: To estimate the risk of suicide attempt repetition among individuals with an index attempt. It also aims to study the role of risk factors and prevention programme in repetition. METHODS: This systematic review and meta-analysis was conducted in keeping with the PRISMA 2020 guidelines. Studies on attempt repetition (both cohort studies and intervention studies) were searched from inception to 2022. RESULTS: A total of 110 studies comprising 248,829 attempters was reviewed. The overall repetition rate was 0.20 (0.17, 0.22). Repetition risk linearly increased over time. A higher risk of attempt repetition was associated with female sex and index attempts in which self-cutting methods were used. Moreover, a mental disorder diagnosis was associated with an increasing repetition risk (OR = 2.02, p < .01). The delivery of a preventive programme reduced the repetition risk, OR = 0.76, p < .05; however, this effect was significant for psychotherapy interventions, OR = 0.38, p < .01. CONCLUSION: One in five suicide attempters will engage in a new suicide attempt. An elevated repetition risk is associated with being female, more severe index methods and psychiatric disorder diagnosis. Preventive programmes, particularly psychotherapy, may contribute to reducing repetition risk and eventually save lives.

Executive dysfunction in eating disorders: Relationship with clinical features.

Eating disorders (ED) are severe mental disorders that may result in significant functional impairment and disability. Neuropsychological studies have consistently found impaired executive function (EF) among ED patients. EF is particularly involved in fundamental skills of daily living and in behavioral and emotional regulation. In this study, impairment of executive functioning is investigated in patients with eating disorders and the associations with clinical features and clinical subtypes are analyzed. METHOD: 75 female patients (m = 22.01 years, sd = 9.15) with eating disorder (43 restrictive anorexia, 30 binge-eating anorexia and 13 bulimia nervosa) and 37 healthy controls (m = 18.54 years, sd = 4.21) were included in the study. An extensive assessment of executive function domains (verbal fluency, set shifting, attention span, selective attention, working memory, inhibitory control and processing speed) was carried out in both groups. Clinical scales for food intake restriction, binge-eating/purging, depression, anxiety and impulsivity were also administered and correlated with scores on executive function tests. RESULTS: Patients with an ED had significantly lower scores than healthy controls in performance of several executive function tests, particularly in set shifting, interference control and processing speed (p < .01, in all three domains). Executive function impairment was related to anxious, depressive and eating disorder symptoms (p < .05), regardless of clinical subtype. CONCLUSIONS: Executive function impairment in eating disorders is associated with greater ED symptomatic severity and might involve a negative treatment outcome. Therefore, cognitive remediation techniques should probably be considered in a number of severe patients with ED.

Suicide mortality in Spain in 2020: The impact of the COVID-19 pandemic.

INTRODUCTION: Suicide constitutes a major concern with evident contribution to global mortality worldwide. Evidence on suicide trends is mixed in the COVID-19 pandemic era. Spain may be an at-risk country for increased suicide risk in the time of COVID-19 pandemic due to prolonged restrictions and lockdown, elevated COVID-19 wave recurrence and related mental health impact. This brief report aims to provide some insight into the suicide mortality trends in the first COVID-19 pandemic year in Spain, using national data. MATERIAL AND METHODS: Data from the National Death Index were used. Annual mortality rate was calculated at a province level under random-effects models for the 2019 and 2020 years. Poisson timeseries regression was used to study the relationship between monthly suicide mortality and COVID-19 pandemic outbreak and lockdown, and second COVID-19 wave peak covariates. RESULTS: 3671 people died by suicide in 2019 in Spain and 3941 people died by suicide in 2020. The random-effects mortality rate in 2019 was 8.3 (CI95=7.6, 9.0) per 100,000 inhabitants, and mortality rate in 2020 was 8.9 (CI95=8.3, 9.6). No significant differences between mortality rates were found (p=.18). The Poisson regression showed a significant relationship between the COVID-19 outbreak and suicide mortality trend, with OR=1.07 (CI95=1.02, 1.12). CONCLUSIONS: Although annual mortality rates were not significantly different, an increased suicide risk was found from May, 2020 onwards. Our results claim for action to tackle suicide in the post-pandemic era taking into account the discouraging upcoming scenario.

Clinical predictors and psychosocial risk factors of suicide attempt severity.

BACKGROUND: Suicide attempts are an important predictor of completed suicide and may differ in terms of severity of medical consequences or medical lethality. There is little evidence on serious suicide attempt (SSA) and very few studies have compared SSA with non-SSA. OBJECTIVE: The aim of this multisite, coordinated, cohort study was to analyze the role of clinical variables and the sociodemographic and psychological risk factors of SSA. METHOD: In this multisite, coordinated, cohort study, 684 participants (222 for the mild suicide attempt group, 371 for the moderate suicide attempt group and 91 for the SSA group) were included in the study. Ordinal regression models were performed to analyze the predictor variables of SSA. RESULTS: Early physical abuse (OR=1.231) and impulsivity (OR=1.036) were predictors of SSA, while depressive symptoms were associated with a lower risk of SSA. CONCLUSION: Environmental and psychological factors as physical abuse and impulsivity are related with severe suicide severity. These findings will help to develop strategies to prevent suicide and may be considered for the treatment and management of suicide.

Risk factors for suicidal behaviour in late-life depression: A systematic review.

BACKGROUND: Suicide is a leading cause of preventable death worldwide, with its peak of maximum incidence in later life. Depression often puts an individual at higher risk for suicidal behaviour. In turn, depression deserves particular interest in old age due to its high prevalence and dramatic impact on health and wellbeing. AIM: To gather integrated evidence on the potential risk factors for suicide behaviour development in depressive older adults, and to examine the effects of depression treatment to tackle suicide behaviour in this population. METHODS: A systematic review of empirical studies, published from 2000 onwards, was conducted. Suicidal behaviour was addressed considering its varying forms (i.e., wish to die, ideation, attempt, and completed suicide). RESULTS: Thirty-five papers were selected for review, comprising both clinical and epidemiological studies. Most of studies focused on suicidal ideation (60%). The studies consistently pointed out that the risk was related to depressive episode severity, psychiatric comorbidity (anxiety or substance use disorders), poorer health status, and loss of functionality. Reduced social support and loneliness were also associated with suicide behaviour in depressive older adults. Finally, the intervention studies showed that suicidal behaviour was a robust predictor of depression treatment response. Reductions in suicidal ideation were moderated by reductions in risk factors for suicide symptoms. CONCLUSION: To sum up, common and age-specific risk factors seem to be involved in suicide development in depressive older adults. A major effort should be made to tackle this serious public health concern so as to promote older people to age healthily and well.

Inflammatory dysregulation in women with an eating disorder: Relationships with altered emotional reactivity.

BACKGROUND: Some studies suggest that inflammatory signaling dysregulation may contribute to eating disorder (ED) pathophysiology. However, little is known about the influence of inflammatory response on altered processes seen among patients with ED, such as emotional processing and reactivity. OBJECTIVES: The objectives were: (a) to investigate the systemic inflammatory response in ED women; and (b) to analyze the role of inflammatory markers in emotional reactivity. METHOD: Concentrations of several intercellular and intracellular inflammatory mediators (cytokines, prostaglandin by-products and enzymes, TBARS, and MAPK proteins) were quantified in plasma and PBMCs from 68 women with an ED (m = 22.01 years, SD = 9.15) and 35 healthy controls (m = 18.54 years, SD = 4.21). Moreover, emotional reactivity to affective pictures (those without either food or thinness content) was studied using the adult (>18 years old) sample (n = 41). RESULTS: Between-group differences were revealed for most markers (TNF-α, PGE2 , COX2, and ratio of activated MAPK proteins), pointing to increased inflammatory response in patients (p < .01). Women with ED showed heightened emotional reactivity, regardless of picture valence. Principal components derived from inflammatory markers showed an explanatory loading on patient's emotional reaction, in terms of valence and arousal. CONCLUSION: This study corroborates the altered systemic inflammatory response in patients with ED. The inflammatory dysregulation may contribute to ED phenotype, as seen by its relationship with heightened emotional reactivity, even though the inflammatory markers were not evaluated throughout the emotional reactivity protocol.
