Review
BACKGROUND
Research indicates that the emergency department is the primary setting for people to present with suicidal ideation. Attempting to provide interventions for this population depends greatly on understanding their needs and life circumstances at the time of presentation to services, therefore enabling more appropriate treatment pathways and services to be provided.
AIM
This review aims to collate, evaluate and synthesize the empirical research focused on the population of people presenting to hospital settings with suicidal ideation.
METHOD
A systematic literature search was performed. Articles that met a specified set of inclusion criteria including participants being over 18, not being admitted to hospital and presenting to an emergency department setting underwent a quality assessment and data analysis. The quality assessment used was the EPHPP Quality Assessment Tool for Quantitative Studies (Thomas et al., 2004).
RESULTS
Twenty-seven articles were included in the review. Studies were quantitative and of reasonable methodological quality (Thomas et al., 2004). The literature was characterized by demographic information, mental health factors associated with the presentation to hospital and treatment pathways or outcomes reported. The reviewed research showed that people presenting to emergency departments with suicidal ideation were varying in age, gender, ethnic background and socio-economic status (SES). Large proportions of studies reported psychosocial factors alongside interpersonal struggles as the main presenting reason. The review highlights large variability across these factors. Mental health diagnosis was common, previous suicide attempt was a risk factor, and treatment pathways were unclear. The review identifies the outstanding gaps and weaknesses in this literature as well as areas in need of future research.
CONCLUSIONS
In conclusion, the review highlights the prevalence of people reporting interpersonal factors as the reason for suicidal ideation and not mental health disorders or diagnosis. Despite this, no mention of trauma or life stories was made in any study assessing this population. Despite a large variation across studies making synthesis difficult, data proves clinically relevant and informative for future practice and guidance on areas needing further research.

Review
Identifying and integrating the neural correlates of suicidal ideation and behaviors is crucial to expand the knowledge and develop targeted strategies to prevent suicide. This review aimed to describe the neural correlates of suicidal ideation, behavior and the transition between them, using different magnetic resonance imaging (MRI) modalities, providing an up-to-date overview of the literature. To be included, the observational, experimental, or quasi-experimental studies must include adult patients currently diagnosed with major depressive disorder and investigate the neural correlates of suicidal ideation, behavior and/or the transition using MRI. The searches were conducted on PubMed, ISI Web of Knowledge and Scopus. Fifty articles were included in this review: 22 on suicidal ideation, 26 on suicide behaviors and two on the transition between them. The qualitative analysis of the included studies suggested alterations in the frontal, limbic and temporal lobes in suicidal ideation associated with deficits in emotional processing and regulation, and in the frontal, limbic, parietal lobes, and basal ganglia in suicide behaviors associated with impairments in decision-making. Gaps in the literature and methodological concerns were identified and might be addressed in future studies.

Meta-Analysis Review
This study was to evaluate the relationship between blood hormone levels and suicidal behaviour. We reviewed Web of Science, PubMed and Embase for literature published up to 10 April 2022. Studies were restricted to English-language articles. Studies measuring blood hormone levels in suicidal and non-suicidal subjects were eligible. Standardized mean differences (SMDs) were applied to evaluate group differences. Overall, 57 studies were eligible, of which 51 evaluated suicide attempts, and 9 assessed suicidal ideation. Random-effects meta-analysis indicated that levels of thyrotropin stimulating hormone (TSH) (SMD = 0.50; 95% CI, 0.27-0.72), leptin (SMD = -1.16; 95% CI, -1.94 to -0.38) and dehydroepiandrosterone sulfate (DHEAS) (SMD = -0.67; 95% CI, -1.13 to -0.21) were related to suicide attempts, whereas progesterone levels (SMD = 0.22; 95% CI, 0.03-0.41) were related to suicidal ideation. This analysis offers evidence linking abnormalities of blood hormones with suicidal behaviour, which may be essential for identifying individuals with suicide attempts and suicidal ideation. Large prospective studies are needed for further clarification of roles of hormones in suicidal behaviour.

Meta-Analysis Review
BACKGROUND
Suicidal ideation, a significant risk factor of suicide, is considered a potential trigger for intervention prior to self-harm or suicide; however, the prevalence of maternal suicidal ideation varied widely between studies. This review aims to synthesis the available evidence to estimate the prevalence of maternal suicidal ideation before and after pregnancy.
METHODS
We searched six English databases (PubMed, Web of Science, Embase, the Cochrane Library, PsycINFO, CINAHL) and three Chinese databases (China National Knowledge Infrastructure, Wang Fang, Chinese Biomedical Literature Databases) from database inceptions before August 31, 2020; and checked the reference list for relevant studies. Data in the included studies were used to calculate the prevalence of maternal suicidal ideation. Subgroup analysis and meta-regression were performed to detect the potential sources of heterogeneity.
RESULTS
6094 potentially studies were identified. 71 studies, including 23 cohort studies, 47 cross-sectional studies, and 1 RCT study, were included for final analysis. The total participants were 92146, with sample size ranged from 23 to 22118. The included studies were from 23 different countries distributing on six continents, most of the studies were conducted in Asia (n = 18), North America (n = 16), and South America (n = 15). The pooled prevalence of maternal suicidal ideation reported by eligible studies was 8% (95% CI 7-10%), with 10% in antenatal and 7% in postpartum. Prevalence significantly varied based on measuring tools, study design, study countries, and publication year, while prevalence was not conditional on the time-point assessment, sample size, and maternal age.
LIMITATION
Obvious heterogeneity and no standardization tools for measuring suicidal ideation may limit the results' interpretation.
CONCLUSION
Our systematic review reported the prevalence of suicidal ideation in pregnancy and postpartum was 8%. Future studies should establish standardization tools for measuring suicidal ideation and identify strategies of prevention and treatment.

OBJECTIVES
Suicidal ideation is a pervasive and painful experience that varies considerably in its phenomenology. Here, we consider how one key risk variable might inform our understanding of variation in suicidal ideation: emotion-related impulsivity, the trait-like tendency towards unconstrained speech, behaviour, and cognition in the face of intense emotions. We hypothesized that emotion-related impulsivity would be tied to specific features, including severity, perceived lack of controllability, more rapidly fluctuating course, higher scores on a measure of acute suicidal affective disturbance, and more emotional and cognitive disturbance as antecedents.
METHODS
We recruited two samples of adults (Ns = 421, 221) through Amazon Mechanical Turk (MTurk), with oversampling of those with suicidal ideation. Both samples completed psychometrically sound self-report measures online to assess emotion- and non-emotion-related dimensions of impulsivity and characteristics of suicidal ideation.
RESULTS
One form of emotion-related impulsivity related to the severity, uncontrollability, dynamic course, and affective and cognitive precursors of ideation.
CONCLUSIONS
Despite limitations of the cross-sectional design and self-report measures, the current findings highlight the importance of specificity in considering key dimensions of impulsivity and suicidal ideation.

OBJECTIVE
The present study seeks to determine differences in lifetime suicidal ideation, dispositional capability, acquired capability, and practical capability among those who have and have not served as first responders, and among subgroups of first responders.
METHODS
Data were collected as part of a large online ( = 3,500) study seeking to understand firearm ownership in the United States. Participants were recruited via Qualtrics Panels and were demographically matched to the 2010 US census. Binary logistic regressions and an exploratory multinomial logistic regression examined differences between first responders and non-first responders and among subgroups of first responders.
RESULTS
First responders reported more lifetime suicidal ideation and higher acquired, practical, and dispositional capability than did non-first responders. Findings indicated that first responders with and without military affiliation did not differ in terms of suicidal ideation or capability for suicide. Lastly, law enforcement officers (LEOs) reported more lifetime suicidal ideation than emergency medical technicians (EMTs). LEOs, EMTs, and firefighters did not differ in terms of capability for suicide.
DISCUSSION
The findings highlight that suicidal ideation and capability for suicide differ between first responders and non-first responders and among subgroups of first responders. The mechanisms driving the increased rates of suicidal ideation and capability among first responders are unknown; however, it is likely due to a combination of personal and occupational factors. Although not without its limitations, the present study provides an understanding of suicide risk among first responders.

While much research exists linking stress and suicidality in cross-sectional paradigms, little is known regarding the longitudinal interplay of stress and suicidality across time. In addition, less research exists on suicidal ideation - a transdiagnostic precursor to suicidal behavior. Two competing, though not mutually exclusive, explanations relate to , where stress causes suicidal ideation, and , where suicidal ideation causes stress. The present study examined 101 adults self-reporting symptoms of borderline personality disorder. Participants completed a self-report measure of suicidal ideation and a life stress interview in a three-wave design over the course of one year. Cross-lagged panel analyses were used to examine the longitudinal relationships between suicidal ideation and interpersonal/non-interpersonal chronic life stress, as well as dependent/interpersonal episodic life stress. Results supported chronic and episodic interpersonal stress generation for suicidal ideation, although not across all timepoints.

BACKGROUND
The exploration of inter- and intra-individual variability in suicidal ideation (SI) is vital to suicide research. However, this research relies on the identification and measurement of standardized SI characteristics.
OBJECTIVE
This review aimed to identify characteristics of SI examined in research, describe how these characteristics are measured, and assess how they are aligned with those included in the Columbia Suicide Severity Rating Scale (C-SSRS).
METHODS
Four databases were systematically searched, and relevant data was extracted. The C-SSRS provided a framework for comparing SI names, measures and operational definitions.
RESULTS
After comparing operational definitions of identified characteristics, five core domains emerged: (1) severity, (2) temporality, (3) variability, (4) controllability, and (5) deterrents/reasons for ideating. Except for variability, all SI characteristics in the literature were congruent with those measured in the C-SSRS.
CONCLUSIONS
This review highlighted conceptual and methodologic inconsistencies in the study of SI, specifically the nomenclature, measurement and definitions of SI characteristics. Standardized approaches to the study of SI characteristics are needed. These approaches will enhance accurate and reliable measurement of SI, allow for findings to be synthesized across studies and propel the exploration of inter and intra-individual SI variability leading to more individualized and effective SI treatment.
