RESUMO
AIMS/HYPOTHESIS: Regulators worldwide are reviewing safety data on glucagon-like peptide-1 receptor agonists (GLP-1RA), following reports by the Icelandic Medicines Agency in July 2023 of suicidal ideation and self-injury (SIS) in individuals taking liraglutide and semaglutide. We aimed to assess the risk of SIS in new users of GLP-1RA when compared with sodium-glucose cotransporter 2 inhibitors (SGLT-2i) users, prescribed to treat type 2 diabetes in individuals with obesity. METHODS: This is a cohort study combining several population-wide databases and covering a Spanish population of five million inhabitants, including all adults with obesity who initiated treatment with either GLP-1RA or SGLT-2i for type 2 diabetes from 2015 to 2021. To estimate the comparative effect of GLP-1RA on the risk of SIS, we employed a new user, active comparator design and we carried out multivariable Cox regression modelling with inverse probability of treatment weighting (IPTW) based on propensity scores. We performed several stratified and sensitivity analyses. RESULTS: We included 3040 patients initiating treatment with GLP-1RA and 11,627 with SGLT-2i. When compared with patients treated with SGLT-2i, those in the GLP-1RA group were younger (55 vs 60 years old, p<0.001), had more anxiety (49.4% vs 41.5%, p<0.001), sleep disorders (43.2% vs 34.1%, p<0.001) and depression (24.4% vs 19.0%, p<0.001), and were more obese (35.1% of individuals with BMI ≥40 vs 15.1%, p<0.001). After propensity score weighting, standardised mean differences between groups were <0.1 for all covariates, showing adequate balance between groups at baseline after adjustment. In the main per-protocol analyses we found no evidence that GLP-1RA increased the incidence of SIS (HR 1.04; 95% CI 0.35, 3.14). Intention-to-treat analyses resulted in an HR of 1.36 (95% CI 0.51, 3.61). In analyses excluding individuals with no BMI information and using imputation for BMI missing values, respective HRs were 0.89 (95% CI 0.26, 3.14) and 1.29 (95% CI 0.42, 3.92). Stratified analyses showed no differences between subgroups. CONCLUSIONS/INTERPRETATION: Our findings do not support an increased risk of SIS when taking GLP-1RA in individuals with type 2 diabetes and obesity; however, the rarity of SIS events and the wide uncertainty of effect size (although null, effect may be compatible with a risk as high as threefold) calls for a cautious interpretation of our results. Further studies, including final evaluations from regulatory bodies, are called for to discard a causal link between GLP-1RA and suicidality.
RESUMO
Despite altered brain activities being associated with suicidal ideation (SI), the neural correlates of SI in major depressive disorder (MDD) have remained elusive. We enrolled 82 first-episode drug-naïve MDD patients including 41 with SI and 41 without SI, as well as 41 healthy controls (HCs). Resting-state functional and structural MRI data were collected. The measures of fractional amplitude of low-frequency fluctuation (fALFF) and grey matter volume (GMV) were calculated and compared. Compared with HCs, patients with SI exhibited increased fALFF values in the right rectus gyrus and left medial superior frontal gyrus, middle frontal gyrus and precuneus. Decreased GMV in the right parahippocampal gyrus, insula and middle occipital gyrus and increased GMV in the left superior frontal gyrus were detected in patients with SI. In addition, patients without SI demonstrated increased fALFF values in the right superior frontal gyrus and decreased fALFF values in the right postcentral gyrus. Decreased GMV in the left superior frontal gyrus, right medial superior frontal gyrus, opercular part of inferior frontal gyrus, postcentral gyrus, fusiform gyrus and increased left supplementary motor area, superior occipital gyrus, right anterior cingulate gyrus and superior temporal gyrus were revealed in patients with SI. Moreover, in comparison with patients without SI, increased fALFF values were identified in the left precuneus of patients with SI. However, no significant differences were found in GMV between patients with and without SI. These findings might be helpful for finding neuroimaging markers predicting individual suicide risk and detecting targeted brain regions for effective early interventions.

OBJECTIVE: We sought to explore relationships of acute dissociative effects of intravenous ketamine with change in depression and suicidal ideation and with plasma metabolite levels in a randomized, midazolam-controlled trial. METHODS: Data from a completed trial in suicidal, depressed participants (n = 40) randomly assigned to ketamine was used to examine relationships between ketamine treatment-emergent dissociative and psychotomimetic symptoms with pre/post-infusion changes in suicidal ideation and depression severity. Nonparametric correlational statistics were used. These methods were also used to explore associations between dissociative or psychotomimetic symptoms and blood levels of ketamine and metabolites in a subset of participants (n = 28) who provided blood samples immediately post-infusion. RESULTS: Neither acute dissociative nor psychotomimetic effects of ketamine were associated with changes in suicidal ideation or depressive symptoms from pre- to post-infusion. Norketamine had a trend-level, moderate inverse correlation with dissociative symptoms on Day 1 post-injection (P = .064; P =.013 removing 1 outlier). Dehydronorketamine correlated with Clinician-Administered Dissociative States Scale scores at 40 minutes (P = .034), 230 minutes (P = .014), and Day 1 (P = .012). CONCLUSION: We did not find evidence that ketamine's acute, transient dissociative, or psychotomimetic effects are associated with its antidepressant or anti-suicidal ideation actions. The correlation of higher plasma norketamine with lower dissociative symptoms on Day 1 post-treatment suggests dissociation may be more an effect of the parent drug.

Suicide is the leading cause of unnatural death among people with a diagnosis of schizophrenia. Alcohol use is a prevalent comorbid feature of schizophrenia and a modifiable risk factor for suicide. We conducted a prospectively registered (PROSPERO, CRD42022358214) systematic review and meta-analysis to quantify the relationship between alcohol use and suicide-related outcomes in schizophrenia.We searched Medline, Embase, and PsycINFO for cross-sectional, case-control and longitudinal studies using exhaustive terms from database inception to December 2022 inclusive. Computation of odds ratios (ORs) and hazard ratios (HRs) were performed using a random-effects model with DerSimonian-Laird estimation. We also evaluated publication bias, study quality, and performed subgroup analysis and meta-regression. Fifty studies, comprising 65 samples, met eligibility criteria. Overall, alcohol use was associated with suicide (OR 1.38, 95% CI 1.21-1.58; HR = 1.32, 95% CI 1.00-1.74), attempted suicide (OR 1.69, 95% CI 1.45-1.98), and suicidal ideation (OR 1.69, 95% CI 1.22-2.34). While there was no evidence of publication bias, between-sample heterogeneity was moderate in analyses of attempted suicide (I2 = 39.6%, p = 0.01) and suicidal ideation (I2 = 56.0%, p = 0.01). Summary effects were significant in all subgroups except for longitudinal studies of attempted suicide (OR 1.60, 95% CI 0.86-3.00) and studies of suicidal ideation using gender combined samples (OR 1.63, 95% CI 0.99-2.67). Alcohol use is significantly associated with suicide-related outcomes in schizophrenia. Clinicians should routinely inquire about alcohol use in mental health services to focus preventative treatment efforts.

BACKGROUND: Suicidal thoughts and behaviors are elevated among active-duty service members (ADSM) and veterans compared to the general population. Hence, it is a priority to examine maintenance factors underlying suicidal ideation among ADSM and veterans to develop effective, targeted interventions. In particular, interpersonal risk factors, hopelessness, and overarousal have been robustly connected to suicidal ideation and intent. METHODS: To identify the suicidal ideation risk factors that are most relevant, we employed network analysis to examine between-subjects (cross-sectional), contemporaneous (within seconds), and temporal (across four hours) group-level networks of suicidal ideation and related risk factors in a sample of ADSM and veterans (participant n = 92, observations n = 10 650). Participants completed ecological momentary assessment (EMA) surveys four times a day for 30 days, where they answered questions related to suicidal ideation, interpersonal risk factors, hopelessness, and overarousal. RESULTS: The between-subjects and contemporaneous networks identified agitation, not feeling close to others, and ineffectiveness as the most central symptoms. The temporal network revealed that feeling ineffective was most likely to influence other symptoms in the network over time. CONCLUSION: Our findings suggest that ineffectiveness, low belongingness, and agitation are important drivers of moment-to-moment and longitudinal relations between risk factors for suicidal ideation in ADSM and veterans. Targeting these symptoms may disrupt suicidal ideation.
RESUMO
BACKGROUNDS: Many autistic people in mental health are suicidal. This study evaluated the effectiveness of dialectical behavior therapy (DBT) v. treatment as usual (TAU) in reducing suicidal ideation and suicide attempts. METHODS: At six Dutch mental health centers, 123 outpatients (18-65 years) with DSM-5 diagnosed autism spectrum disorder (ASD) and suicidal behavior were randomly assigned to the DBT intervention group (n = 63) or TAU control group (n = 60). Assessments were conducted at baseline, post-treatment at 6 months and 12-month follow-up. The primary outcomes were severity of suicidal ideation and frequency of suicide attempts. The severity of depression and social anxiety were secondary outcomes. RESULTS: At end-of-treatment, DBT significantly reduced both suicidal ideation (z = -2.24; p = 0.025; b = -4.41; s.e. = 197.0) and suicide attempts (z = -3.15; p = 0.002; IRR = 0.046; s.e. = 0.045) compared to TAU, but lost statistical significance at the 12-month follow-up. Depression severity significantly decreased with DBT (z = -1.99; p = 0.046: b = -2.74; s.e. = 1.37) remaining so at 12 months (z = -2.46; p = 0.014; b = -3.37; s.e. = 1.37). No effects were observed on social anxiety. Severe adverse events included two suicides in the TAU condition. CONCLUSIONS: DBT is an acceptable, safe, and short-term effective intervention to reduce suicidal ideation and suicide attempts in autistic adults with suicidal behavior.
RESUMO
BACKGROUND: Little is known about when youth may be at greatest risk for attempting suicide, which is critically important information for the parents, caregivers, and professionals who care for youth at risk. This study used adolescent and parent reports, and a case-crossover, within-subject design to identify 24-hour warning signs (WS) for suicide attempts. METHODS: Adolescents (N = 1094, ages 13 to 18) with one or more suicide risk factors were enrolled and invited to complete bi-weekly, 8-10 item text message surveys for 18 months. Adolescents who reported a suicide attempt (survey item) were invited to participate in an interview regarding their thoughts, feelings/emotions, and behaviors/events during the 24-hours prior to their attempt (case period) and a prior 24-hour period (control period). Their parents participated in an interview regarding the adolescents' behaviors/events during these same periods. Adolescent or adolescent and parent interviews were completed for 105 adolescents (81.9% female; 66.7% White, 19.0% Black, 14.3% other). RESULTS: Both parent and adolescent reports of suicidal communications and withdrawal from social and other activities differentiated case and control periods. Adolescent reports also identified feelings (self-hate, emotional pain, rush of feelings, lower levels of rage toward others), cognitions (suicidal rumination, perceived burdensomeness, anger/hostility), and serious conflict with parents as WS in multi-variable models. CONCLUSIONS: This study identified 24-hour WS in the domains of cognitions, feelings, and behaviors/events, providing an evidence base for the dissemination of information about signs of proximal risk for adolescent suicide attempts.

BACKGROUND: Although the link between alcohol involvement and behavioral phenotypes (e.g. impulsivity, negative affect, executive function [EF]) is well-established, the directionality of these associations, specificity to stages of alcohol involvement, and extent of shared genetic liability remain unclear. We estimate longitudinal associations between transitions among alcohol milestones, behavioral phenotypes, and indices of genetic risk. METHODS: Data came from the Collaborative Study on the Genetics of Alcoholism (n = 3681; ages 11-36). Alcohol transitions (first: drink, intoxication, alcohol use disorder [AUD] symptom, AUD diagnosis), internalizing, and externalizing phenotypes came from the Semi-Structured Assessment for the Genetics of Alcoholism. EF was measured with the Tower of London and Visual Span Tasks. Polygenic scores (PGS) were computed for alcohol-related and behavioral phenotypes. Cox models estimated associations among PGS, behavior, and alcohol milestones. RESULTS: Externalizing phenotypes (e.g. conduct disorder symptoms) were associated with future initiation and drinking problems (hazard ratio (HR)⩾1.16). Internalizing (e.g. social anxiety) was associated with hazards for progression from first drink to severe AUD (HR⩾1.55). Initiation and AUD were associated with increased hazards for later depressive symptoms and suicidal ideation (HR⩾1.38), and initiation was associated with increased hazards for future conduct symptoms (HR = 1.60). EF was not associated with alcohol transitions. Drinks per week PGS was linked with increased hazards for alcohol transitions (HR⩾1.06). Problematic alcohol use PGS increased hazards for suicidal ideation (HR = 1.20). CONCLUSIONS: Behavioral markers of addiction vulnerability precede and follow alcohol transitions, highlighting dynamic, bidirectional relationships between behavior and emerging addiction.
RESUMO
BACKGROUND: Major depressive disorder (MDD) contributes to suicide risk. Treating MDD effectively is considered a key suicide prevention intervention. Yet many patients with MDD do not respond to their initial medication and require a 'next-step'. The relationship between next-step treatments and suicidal thoughts and behaviors is uncharted. METHOD: The VA Augmentation and Switching Treatments for Depression trial randomized 1522 participants to one of three next-step treatments: Switching to Bupropion, combining with Bupropion, and augmenting with Aripiprazole. In this secondary analysis, features associated with lifetime suicidal ideation (SI) and attempts (SA) at baseline and current SI during treatment were explored. RESULTS: Compared to those with SI only, those with lifetime SI + SA were more likely to be female, divorced, or separated, unemployed; and to have experienced more childhood adversity. They had a more severe depressive episode and were more likely to respond to 'next-step' treatment. The prevalence of SI decreased from 46.5% (694/1492) at baseline to 21.1% (315/1492) at end-of-treatment. SI during treatment was associated with baseline SI; low positive mental health, more anxiety, greater severity and longer duration of current MDD episode; being male and White; and treatment with S-BUP or C-BUP as compared to A-ARI. CONCLUSION: SI declines for most patients during next-step medication treatments. But about 1 in 5 experienced emergent or worsening SI during treatment, so vigilance for suicide risk through the entire 12-week acute treatment period is necessary. Treatment selection may affect the risk of SI.

Huntington's disease (HD) is an autosomal-dominant progressive neurodegenerative disease that manifests with a triad of symptoms including motor dysfunctions, cognitive deficits, and prominent neuropsychiatric symptoms, the most common of which is depression, with a prevalence between 30 and 70%. Depressive symptoms occur in all stages of HD, beginning in presymptomatic HD gene carriers, and are strongly associated with suicidal ideation and suicidality, but their relationship with other clinical dimensions in HD is controversial and the underlying pathophysiology is poorly understood. Analysis of the available literature until November 2023 concerned the prevalence, clinical manifestations, neuroimaging, transgenic models, and treatment options of HD depression. While it was believed that depression in HD is due to psychosomatic factors in view of the fatal disease, studies in transgenic models of HD demonstrated molecular changes including neurotrophic and serotonergic dysregulation and disorders of the hypothalamic-pituitary-adrenal axis inducing depression-like changes. While relevant neuropathological data are missing, recent neuroimaging studies revealed correlations between depressive symptoms and dysfunctional connectivities in the default mode network, basal ganglia and prefrontal cortex, and changes in limbic and paralimbic structures related to the basic neurodegenerative process. The impact of response to antidepressants in HD patients is controversial; selective serotonin reuptake inhibitors are superior to serotonin-norepinephrine reuptake inhibitors, while electroconvulsive therapy may be effective for pharmacotherapy resistant cases. Since compared to major depressive disorder and depression in other neurodegenerative diseases, our knowledge of the molecular basis in HD depression is limited, further studies to elucidate the heterogeneous pathogenesis in this fatal disorder are warranted.
RESUMO
BACKGROUND: Young children involved in the child welfare system (CWS) are at high risk for suicidal ideation (SI) at a time when overall rates of suicide death in this age group are rising. Yet risk factors for and changes in SI over time are poorly understood in this population. METHOD: We combined data from two large representative longitudinal studies of children involved in the United States CWS. We examined patterns of SI among children who were between ages 7 and 12 years at the initial survey wave (N = 2,186), assessed at three waves using a measure of SI in the past 2 weeks. We conducted a multinomial regression to understand the baseline demographic, child maltreatment, and mental health characteristics that distinguish the trajectories. RESULTS: There were eight different subgroups (Non-Ideators, Late Ideators, Boomerang Ideators, Delayed Ideators, Desisters, Boomerang Non-Ideators, Late Desisters, and Persisters). Differences in race, type of maltreatment, sex, and mental health symptoms were identified when comparing Persisters (SI at all three waves) to other groups. CONCLUSIONS: These findings can help researchers and practitioners to develop strategies for better identifying CWS-involved children who are in greatest need of suicide risk monitoring and intervention.
RESUMO
Researchers at the intersection of sleep and suicide research have advocated for investigation of sleep disturbances as a therapeutic target for the purposes of treating and preventing suicide. This study aims to provide the first systematic review and meta-analysis on the efficacy of sleep interventions to treat suicidal ideation. This systematic review and meta-analysis, registered with the International Prospective Register of Systematic Reviews, was conducted in PsycINFO, through Ovid. A sample of eight articles were deemed eligible and a total of 21 effect sizes were included. Egger's test suggested that no publication bias was present (b = 0.3695; p = 0.0852). The pooled effect size for sleep treatments on suicidal ideation was small (g = -0.0931, p = 0.3047). Significant heterogeneity was present (I2 = 44.13%), indicating the need for moderator analyses. Treatment type (medication versus psychotherapy; g = -0.2487, p = 0.3368), sex (g = -0.0007; p = 0.9263), and race (g = -0.0081; p = 0.1624) were all considered as moderators and were all found to be insignificant. This meta-analysis revealed that initial studies exploring the efficacy of sleep interventions on suicidal ideation demonstrate small effect sizes. Despite this, the handful of studies included in this review nonetheless highlight this as an important area for continued exploration. The use of larger and more diverse samples, as well as intentionally designing sleep-related interventions to improve ideation and behaviour, have the potential to enhance the efficacy of sleep interventions for this novel purpose.

OBJECTIVE: Perform a secondary analysis examining the efficacy of the Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C) for depression symptom responses, and explore changes in potential target mechanisms. DESIGN: Secondary analysis of a randomized controlled trial with convenience age subsamples (younger (20-49 year; n = 52) versus and older (50-71 years; n = 35)). SETTING: Community mental health clinics. PARTICIPANTS: Eighty-seven adults with serious mental illness. INTERVENTION: TranS-C versus treatment as usual (TAU). MEASUREMENTS: Outcomes were depression symptoms (Quick Inventory of Depression Symptoms), insomnia symptoms (Insomnia Severity Index), and objective sleep-wake rhythm measures (interdaily stability and relative amplitude). RESULTS: Depression response rates (≥50% symptom reductions) were higher in the TranS-C (35.0%) than the TAU (8.8%) group 6-months postintervention (χ2 = 10.3, p = 0.001). There was a medium effect of TranS-C versus TAU on depression symptoms 6-months postintervention (Cohen's d = -0.40, 95% confidence interval (CI): -0.81, 0.01). In both age groups, there were large treatment effects on insomnia symptoms post-treatment (Cohen's d >0.90). In the older subsample, there were additionally medium treatment effects on post-treatment interdaily stability (Cohen's d = 0.60, 95% CI: -0.11, 1.61). Post-treatment reductions in insomnia symptoms correlated with depression symptom reduction 6-months later in the younger subsample (Spearman rho = 0.59, n = 20, p = 0.008). In older adults, postintervention increases in interdaily stability correlated with depression symptom reductions 6-months later (Spearman rho = -0.52, n = 15, p = 0.049). CONCLUSION: Confirmatory trials are needed, given the low age-specific sample sizes here, to determine if TranS -C's produces durable depression responses by increasing sleep-wake rhythm stability in older adults and improving insomnia symptoms in younger adults. BRIEF ARTICLE SUMMARY: The authors evaluated preliminary efficacy of a behavioral intervention that targets sleep/sleep-wake rhythms, the Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C), for depression symptoms in people with serious mental illness. TranS-C was associated with higher depression response rates than treatment as usual 6-months postintervention. The degree of depression symptom response 6-months later was related to the degree of treatment phase improvements in interdaily stability (in older adults) and reduction in insomnia severity (in younger adults). A pragmatic nonpharmacologic intervention, the Transdiagnostic Intervention for Sleep and Circadian Dysfunction, has preliminary efficacy for improving sleep-wake factors and depression symptoms.

OBJECTIVE: To evaluate whether timely follow-up outpatient mental health care is associated with reduced short-term suicide risk following hospitalization for suicidal thoughts or behaviors. METHODS: Retrospective cohort analysis using 2015 Medicare data for adults aged ≥ 65 years who were hospitalized for suicidal ideation or behaviors (n = 36,557) linked with the National Death Index. Adjusted risk ratios (ARR) estimated the association between 7-day follow-up and suicide risk at 30-, 90-, and 180-days, adjusted for confounding by indication using inverse probability of treatment weights of observable covariates. RESULTS: Overall, 39.3% of patients received 7-day follow-up, which was associated with 41% higher risk of suicide within 180 days. Follow-up care was associated with higher suicide risk for Medicare Advantage enrollees, patients with no recent prior mental health care, and those admitted for suicidal behaviors. CONCLUSION: Results suggest 7-day follow-up care was not associated with lower post-discharge suicide risk. For this high-risk group, suicide-specific interventions may be needed during the critical postdischarge period.

PURPOSE: The goal of this study was to inform theory and suicide prevention efforts by examining how the link between attempts to change weight and suicidal ideation varies across adolescence, when it is strongest, and whether there are sex differences. METHODS: Data were from 13,518 youth ages 14-18 years who participated in the 2019 Youth Risk Behavior Survey, a nationally representative study of U.S. high school students. Time-varying effect modeling was used to estimate associations between attempts to change weight and suicidal ideation as continuous functions of age and to test sex differences in these links. RESULTS: The link between attempts to lose weight and suicidal ideation was positive and significant between ages 14.0-17.3 years, with the strongest association at age 15.0 (OR = 2.07). There were no sex differences in this age-varying association. The association between attempts to gain weight and suicidal ideation was positive and age-varying for girls, with the strongest association at age 17.2 years (OR = 2.79). This association was not significant for boys at any age. CONCLUSIONS: Girls and boys who are trying to lose weight and girls who are trying to gain weight may be at elevated risk for suicidal ideation between ages 14 and 18 years. Findings illuminate patterns of association during adolescence and have implications for suicide prevention.
RESUMO
INTRODUCTION: Suicidal ideation variability refers to within-day fluctuations in suicidal ideation, and has recently been proposed as an indicator of suicide risk. However, not much is known yet about its correlates and clinical relevance. METHODS: We examined characteristics of real-time suicidal ideation using Ecological Momentary Assessment in 82 individuals with current active suicidal ideation. Data were collected four times daily over 21 days. Latent profile analysis was used to identify subtypes of suicidal ideation. We further examined sociodemographic and clinical correlates of the profiles, and their association with the occurrence of suicide attempts during a 1-year follow-up. RESULTS: We identified three "digital" phenotypes of suicidal ideation that differed on the frequency, intensity and variability of ideation. The profiles were: high frequency, high intensity, moderate variability (Phenotype 1), moderate/high frequency, moderate intensity, high variability (Phenotype 2), and moderate frequency, low intensity, low variability (Phenotype 3). Phenotypes 1 and 2 were associated with a worse clinical profile at baseline (higher suicidal ideation and depressive symptom severity), and increased odds of suicide attempt during follow-up, compared to Phenotype 3. Phenotype 1 was further characterized by repeated suicidal behavior. CONCLUSIONS: Two phenotypes of real-time suicidal ideation were identified that appear to confer a higher risk of suicidal behavior in the near future (12 months). These phenotypes were characterized by higher variability of suicidal ideation-and also higher intensity and frequency of ideation. Considering the small sample size, the clinical usefulness of the profiles remains to be demonstrated.
RESUMO
Suicidal ideation and depression are common in people living with HIV (PLWH) in sub-Saharan Africa, but longitudinal data on their persistence in the modern antiretroviral therapy era are lacking. We examined the prevalence of persistent suicidal ideation and depression symptoms using the PHQ-9 in a well-characterized cohort of PLWH and HIV-uninfected community controls. Multivariable logistic regression models were used to determine the relationship between HIV and persistent depression and suicidal ideation. Persistent suicidal ideation was more common in PLWH but there was no difference in persistent depression by HIV status. Approximately one out of five participants with depression at baseline had persistent depression after 12-24 months and only about one out of four participants reporting suicidal ideation at baseline had persistent suicidal ideation after 12-24 months. HIV was associated with suicidal ideation at baseline. Persistent suicidal ideation was significantly associated with HIV immune non-response (p = 0.022). These findings highlight the need for integration of mental health services into HIV care in sub-Saharan Africa with a focus on suicide prevention.
RESUMO
Cancer in adolescents and young adults is associated with an increased risk for suicidal ideation (SI). There are no reported pediatric oncology cases describing management of SI during end of life. We present the case of a 14-year-old male with relapsed, high-risk, B-cell acute lymphoblastic leukemia who received a haploidentical stem cell transplant and was suicidal at various points in his treatment. We discuss how to manage acute suicidality in this patient population, the importance of giving a voice to the adolescent patient, the impact of discordant goals of care, and potential preventive strategies for similar cases.

OBJECTIVES: The focus of this research was to explore any potential link between nocturia and the risk of suicidal ideation. METHODS: Drawing from the National Health and Nutrition Survey, data relating to 25 241 participants was scrutinized. This included 13 421 individuals identifying as male and 11 820 individuals identifying as female. Participants provided information on nocturia and suicidal ideation via self-completed questionnaires. To determine if nocturia was independently related to suicidal ideation, a multivariable logistic regression analysis was employed. Analyses were also undertaken separately for adult males and females. RESULTS: It was found that around 3.5% of participants had experienced suicidal ideation. The results indicated that nocturia increased the risk for suicidal ideation in all adult groups (odds ratio [OR] = 1.67, 95% confidence interval[CI]: 1.37-2.03, p < 0.0001), including both males (OR = 1.91, 95% CI: 1.38-2.65, p < 0.001) and females (OR = 1.48, 95% CI: 1.158-1.90, p = 0.002). The risk for suicidal ideation increased with the severity of nocturia, with significant trends observed in adult males (p for trend = 0.04) and adult females (p for trend = 0.01). Additionally, subgroup examination showed a significant interaction between nocturia and educational level in adult males (p for interaction = 0.03). Among adult females, a noteworthy interaction was observed between nocturia and body mass index (p for interaction = 0.02). CONCLUSION: The research uncovered a connection between nocturia and an elevated risk of suicidal ideation.
RESUMO
OBJECTIVE: Traumatic brain injury (TBI) is a risk factor for suicide, but questions related to mechanisms remain unanswered. Impulsivity is a risk factor for suicide and is a common sequela of TBI. The authors explored the relationships between TBI and both suicidal ideation and suicide attempts and explored whether impulsivity and comorbid psychiatric diagnoses mediate these relationships. METHODS: This cross-sectional retrospective chart review study included 164 veterans enrolled in a previous study. Sixty-nine veterans had no TBI history, and 95 had a TBI history (mild, N=44; moderate, N=13; severe, N=12; and unclear severity, N=26). To examine the associations between TBI and suicidal ideation or suicide attempts, as well as potential mediators of these relationships, chi-square tests, t tests, and logistic regression models were used. RESULTS: Unadjusted analyses indicated that veterans with TBI were more likely to report suicidal ideation; however, in analyses controlling for mediators, this relationship was no longer significant. Among veterans with TBI, suicidal ideation was related most strongly to high impulsivity (odds ratio=15.35, 95% CI=2.43-96.79), followed by depression (odds ratio=5.73, 95% CI=2.53-12.99) and posttraumatic stress disorder (odds ratio=2.57, 95% CI=1.03-6.42). TBI was not related to suicide attempts, yet suicide attempts were related to high impulsivity (odds ratio=6.95, 95% CI=1.24-38.75) and depression (odds ratio=3.89, 95% CI=1.56-9.40). CONCLUSIONS: These findings suggest that impulsivity, followed by psychiatric diagnoses, most strongly mediate the relationships between TBI and both suicidal ideation and suicide attempts. Impulsivity may be mechanistically related to, and serve as a future treatment target for, suicidality among veterans with TBI.
