RESUMO

Objective: Most assessments of suicidal ideation and behavior (SIB) are limited by reliance on a single assessor, typically a clinician or patient, with scant detail on patient-related drivers of SIB and inability to detect rapid change in SIB. Furthermore, many techniques do not include a semistructured interview, increasing rater variability. The Suicide Ideation and Behavior Assessment Tool (SIBAT) addresses these limitations. Design: More than 30 experts in scale development, statistics, and clinical management of suicidal patients collaborated over a greater than four-year period to develop the SIBAT. Input for content and validity was received from patients, clinicians, and regulatory authorities in the United States (US) and Europe. Psychometric properties of the SIBAT were evaluated in validation studies. Results: The SIBAT is organized into eight independent patient- or clinician-rated modules with branching logic and scoring algorithms, which necessitates computerization. Patient-reported information is first captured in Modules 1 to 5. Thereafter, an experienced clinician reviews the patient's report, conducts a semistructured interview (Module 6), and assesses the patient's suicide risk (Module 7) and optimal antisuicide management (Module 8). Input from cognitive interviews of diverse adult, adolescent, and clinician participants was incorporated into the final version of the SIBAT. Psychometric testing demonstrated good inter-rater reliability (intraclass coefficient range: 0.68-0.82), intra-rater reliability (weighted-kappa range: 0.64-0.76), and concurrent validity with other instruments for assessing SIB. Conclusion: Patient- and clinician-based assessments and the psychometric studies summarized in this report support the validity and reliability of the SIBAT for capturing critical information related to assessment of SIB in adolescents and adults at risk for suicide.

RESUMO

BACKGROUND: Suicidal patients often present to the emergency department, where specific anti-suicidal treatment is lacking. Ketamine, a Glutamate modulator and a rapidly acting antidepressant with anti-suicidal properties, might offer relief. AIMS: Evaluation of single, fixed-dosed intranasal ketamine for acute suicidal ideation in the emergency department. METHODS: Between August 2016 and April 2018, 30 eligible suicidal subjects, scheduled for psychiatric hospitalization, independently of their psychiatric diagnosis, were randomized to intranasal ketamine 40 mg or saline placebo. Safety and efficacy evaluations were scheduled for 30, 60, 120 and 240 min post administration and on days 1, 2, 3, 4, 5, 7, 21 and 28. Primary outcome was suicidal ideation. RESULTS: Fifteen subjects were randomized for each study group. All were analyzed for primary and secondary outcomes. Four hours post administration, the mean difference in suicidal symptoms between the groups, measured by the Montgomery-Åsberg Depression Rating Scale (MADRS) item of suicidal thoughts (MADRS-SI), was 1.267 (95% confident interval 0.1-2.43, p < 0.05) favoring treatment. Remission from suicidal ideation was evident in 80% for the ketamine group compared with 33% for the controls (p < 0.05). The mean difference in depressive symptoms, measured by MADRS, at the same time was 9.75 (95% confident interval 0.72-18.79, p < 0.05) favoring ketamine. Treatment was safe and well-tolerated. CONCLUSIONS: Single, fixed-dose, intranasal ketamine alleviated suicidal ideation and improved depressive symptoms four hours post administration. We present here an innovative paradigm for emergency department management of suicidal individuals. Future larger-scale studies are warranted. ClinicalTrials.gov Identifier: NCT02183272.

RESUMO

Selective serotonin reuptake inhibitors (SSRIs) have anti-inflammatory properties that may have clinical utility in treating severe pulmonary manifestations of COVID-19. SSRIs exert anti-inflammatory effects at three mechanistic levels: (a) inhibition of proinflammatory transcription factor activity, including NF-κB and STAT3; (b) downregulation of lung tissue damage and proinflammatory cell recruitment via inhibition of cytokines, including IL-6, IL-8, TNF-α, and IL-1ß; and (c) direct suppression inflammatory cells, including T cells, macrophages, and platelets. These pathways are implicated in the pathogenesis of COVID-19. In this review, we will compare the pathogenesis of lung inflammation in pulmonary diseases including COVID-19, ARDS, and chronic obstructive pulmonary disease (COPD), describe the anti-inflammatory properties of SSRIs, and discuss the applications of SSRIS in treating COVID-19-associated inflammatory lung disease.

RESUMO

Hyperinflammatory response caused by infections such as Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) increases organ failure, intensive care unit admission, and mortality. Cytokine storm in patients with Coronavirus Disease 2019 (COVID-19) drives this pattern of poor clinical outcomes and is dependent upon the activity of the transcription factor complex nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kappaB) and its downstream target gene interleukin 6 (IL6) which interacts with IL6 receptor (IL6R) and the IL6 signal transduction protein (IL6ST or gp130) to regulate intracellular inflammatory pathways. In this study, we compare transcriptomic signatures from a variety of drug-treated or genetically suppressed (i.e. knockdown) cell lines in order to identify a mechanism by which antidepressants such as fluoxetine demonstrate non-serotonergic, anti-inflammatory effects. Our results demonstrate a critical role for IL6ST and NF-kappaB Subunit 1 (NFKB1) in fluoxetine's ability to act as a potential therapy for hyperinflammatory states such as asthma, sepsis, and COVID-19.

RESUMO

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a worldwide pandemic, infecting over 16 million people worldwide with a significant mortality rate. However, there is no current Food and Drug Administration-approved drug that treats coronavirus disease 2019 (COVID-19). Damage to T lymphocytes along with the cytokine storm are important factors that lead to exacerbation of clinical cases. Here, we are proposing intravenous oxytocin (OXT) as a candidate for adjunctive therapy for COVID-19. OXT has anti-inflammatory and proimmune adaptive functions. Using the Library of Integrated Network-Based Cellular Signatures (LINCS), we used the transcriptomic signature for carbetocin, an OXT agonist, and compared it to gene knockdown signatures of inflammatory (such as interleukin IL-1ß and IL-6) and proimmune markers (including T cell and macrophage cell markers like CD40 and ARG1). We found that carbetocin's transcriptomic signature has a pattern of concordance with inflammation and immune marker knockdown signatures that are consistent with reduction of inflammation and promotion and sustaining of immune response. This suggests that carbetocin may have potent effects in modulating inflammation, attenuating T cell inhibition, and enhancing T cell activation. Our results also suggest that carbetocin is more effective at inducing immune cell responses than either lopinavir or hydroxychloroquine, both of which have been explored for the treatment of COVID-19.

RESUMO

BACKGROUND: Depressed patients presenting to emergency departments with acute suicidal ideation are a major public health concern. Ketamine, a rapidly acting antidepressant with antisuicidal properties, might offer relief. METHODS: In a randomized, double-blind, placebo-controlled, proof-of-concept trial, 18 depressed subjects with acute suicidal ideation, who required hospitalization, were randomized to either an intravenous ketamine 0.2 mg/kg group or a saline placebo group. Safety and efficacy evaluations were scheduled for 15, 30, 60, 90, 120, 180, and 240 min, and on Days 1, 2, 3, 7, and 14 after infusion. The main outcome measure was suicidal ideation with secondary measures of depression. RESULTS: Nine subjects were randomized to each group. There were no differences between groups at baseline in any demographic or assessment scales. A reduction in suicidal ideation was noted at 90-180 min (p < .05). Ninety minutes after infusion, 88% of the ketamine group had achieved remission of suicidal ideation compared with 33% in the placebo group (p < .05). No serious adverse events were noted. CONCLUSIONS: Ketamine was safe and effective for rapid reduction in suicidal ideation in depressed, highly suicidal subjects presenting to the emergency department. Our results support further study of ketamine for acute suicidal ideation.

RESUMO

OBJECTIVE: Following traumatic brain injury (TBI), depressive symptoms are common and may influence recovery. We performed a meta-analysis to estimate the benefit of antidepressants following TBI and compare the estimated effects between antidepressants and placebo. PARTICIPANTS: Multiple databases were searched to find prospective pharmacological treatment studies of major depressive disorder (MDD) in adults following TBI. MAIN MEASURES: Effect sizes for antidepressant medications in patients with TBI were calculated for within-subjects designs that examined change from baseline after receiving medical treatment and treatment/placebo designs that examined the differences between the antidepressants and placebo groups. DESIGN: A random-effects model was used for both analyses. RESULTS: Of 1028 titles screened, 11 were included. Pooled estimates showed nonsignificant difference in reduction of depression scores between medications and placebo (standardized mean difference of 5 trials = -0.3; 95% CI, -0.6 to 0.0; I = 17%), and a significant reduction in depression scores for individuals after pharmacotherapy (mean change = -11.2; 95% CI, -14.7 to -7.6 on the Hamilton Depression Scale; I = 87%). CONCLUSIONS: This meta-analysis found no significant benefit of antidepressant over placebo in the treatment of MDD following TBI. Pooled estimates showed a high degree of bias and heterogeneity. Prospective studies on the impact of antidepressants in well-defined cohorts of TBI patients are warranted.

RESUMO

OBJECTIVE: This study sought to describe the association between spiritual well-being, demographic characteristics, quality of life (QOL) and depressive symptoms following spinal cord injury (SCI). We hypothesized QOL and depressed mood would both be explained by extent of spiritual well-being, and meaning-focused (M&P) spirituality would have a stronger impact than faith-focused spirituality. METHODS: 210 individuals with SCI were screened as part of a randomized control trial of venlafaxine XR for major depressive disorder (MDD). 204 completed all measures: Patient Health Questionniare-9 (PHQ-9) assessed depression, the FACIT-Sp assessed spiritual well-being, the Neuro-QOL PAWB scale assessed QOL, and the PANAS assessed affect. RESULTS: Approximately 26% had major depression. Bivariate correlations of scores on PAWB and PANAS and FACIT-Sp showed that all four scales had strong associations with those on PAWB (p < 0.0005). As hypothesized, both the M&P and Faith scales of the FACIT-Sp were significant predictors of QOL (ß = 0.544; p < 0.0005 and ß = 0.151; p = 0.004), though only the M&P scale was an independently significant predictor of likely MDD. CONCLUSION: The findings support that spirituality, as measured by the FACIT-Sp, is strongly associated with QOL and likelihood of MDD. Assessment of spirituality should be included along with more traditional psychological measurements to better inform treatment. Implications for Rehabilitation Spiritual beliefs can contribute to quality of life and may help moderate depressive symptoms that accompany chronic illness and disability, suggesting that rehabilitation professionals should address spirituality in working with their patients with spinal cord injury (SCI). While spiritual issues are often deferred to pastoral counselors during hospitalization, it is clear that addressing these is not the domain of one discipline and does not end upon inpatient discharge. In addressing spirituality, clinicians should tap the spiritual strengths present in their clients, whether meaning/peace-focused or religious, understanding that spirituality involves more than religiosity and also that having a sense of meaning and peace appears to be of great importance.

RESUMO

The study goal was to determine whether a significant number of high suicide risk individuals would confidentially put their own names onto a list to prevent future gun purchases. An anonymous written survey was administered in an inpatient psychiatric unit and two outpatient psychiatric clinics at an academic medical center. Two hundred forty individuals were approached to fill out the survey, of whom 200 (83.3%) did so. Forty-six percent of participants stated that they would put their own name onto the list. This novel suicide prevention proposal, a Do-Not-Sell List, would appeal to many people at high risk for suicide.

RESUMO

Death by suicide demonstrates profound personal suffering and societal failure. While basic sciences provide the opportunity to understand biological markers related to suicide, computer science provides opportunities to understand suicide thought markers. In this novel prospective, multimodal, multicenter, mixed demographic study, we used machine learning to measure and fuse two classes of suicidal thought markers: verbal and nonverbal. Machine learning algorithms were used with the subjects' words and vocal characteristics to classify 379 subjects recruited from two academic medical centers and a rural community hospital into one of three groups: suicidal, mentally ill but not suicidal, or controls. By combining linguistic and acoustic characteristics, subjects could be classified into one of the three groups with up to 85% accuracy. The results provide insight into how advanced technology can be used for suicide assessment and prevention.

RESUMO

Ketamine, an NMDA receptor antagonist with efficacy as a rapid anti-depressant, has early evidence for action to reduce suicidal ideation. This review will explore several important questions that arise from these studies. First, how do we measure reductions in suicidal ideation that occur over minutes to hours? Second, are the reductions in suicidal ideation after ketamine treatment solely a result of its rapid anti-depressant effect? Third, is ketamine only effective in reducing suicidal ideation in patients with mood disorders? Fourth, could ketamine's action lead us to a greater understanding of the neurobiology of suicidal processes? Last, do the reductions in depression and suicidal ideation after ketamine treatment translate into decreased risk for suicidal behavior? Our review concludes that ketamine treatment can be seen as a double-edged sword, clinically to help provide treatment for acutely suicidal patients and experimentally to explore the neurobiological nature of suicidal ideation and suicidal behavior.

RESUMO

BACKGROUND: The prevalence of smoking among HIV-infected individuals is 2-3 times that of the general population, increasing the risk of smoking-related morbidity and mortality. We examined characteristics associated with smoking behavior among a large cohort of HIV-infected individuals in care in the United States. METHODS: A convenience sample of 2952 HIV-infected patients in the Centers for AIDS Research (CFAR) Network of Integrated Clinical Systems (CNICS) was assessed during routine clinic visits and was included. Multinomial logistic regression was used to examine the relationship between smoking status, depression/panic symptoms, alcohol/substance use, and demographic and clinical characteristics. RESULTS: Compared with never-smokers, current smokers were more likely to have moderate to severe depression (odds ratio [OR] 1.37), endorse current substance use (OR 14.09), and less likely to report low-risk alcohol use on the Alcohol Use Disorders Identification Test (AUDIT-C) (OR 0.73). Current smokers were less likely to have an undetectable viral load (OR 0.75), and more likely to have current substance abuse (OR 2.81) and moderate to severe depression (OR 1.50), relative to smokers who had quit smoking. CONCLUSIONS: HIV-infected smokers are less likely to have undetectable viral loads and frequently have psychosocial comorbidities including depression and substance abuse that impact antiretroviral therapy adherence and viral load suppression. To be effective, smoking-cessation interventions need to address the complex underlying concurrent risks in this population.

RESUMO

OBJECTIVE: To determine unique associations of suicidal ideation (SI) and lifetime suicide attempts (SAs) in individuals with spinal cord injury (SCI). DESIGN: Cross-sectional analysis. SETTING: Outpatient. PARTICIPANTS: Individuals with SCI (N=2533) who were 18 years or older with a history of traumatic SCI. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Any SI in the past 2 weeks (9-item Patient Health Questionnaire) and any lifetime SA. RESULTS: Three hundred twenty-three individuals (13.3%) reported SI in the past 2 weeks and 179 (7.4%) reported lifetime SA. After controlling for other factors, both lifetime SA and current SI were associated with study site and current level of depression. In addition, SA was associated with less education, younger age at injury, having current or past treatment of depression, and having bipolar disorder or schizophrenia. SI was associated with more years since injury and lifetime SA. Several psychological factors were associated with current SI and lifetime SAs, including lower environmental reward and less positive affect. In addition, control of one's community activities and spiritual well-being were associated with current SI. In bivariate comparisons, severity of SCI was also associated with the 47% of the SAs that occurred after injury. CONCLUSIONS: Several unique associations of SI and lifetime SA in individuals with SCI were identified, including level of environmental reward and control, spiritual well-being, and severity of SCI. These factors bear further investigation as prospective risk factors for suicidal behavior after SCI.

RESUMO

IMPORTANCE: Depression is prevalent and associated with negative outcomes in individuals with spinal cord injury (SCI). Antidepressants are used routinely to treat depression, yet no placebo-controlled trials have been published in this population to our knowledge. OBJECTIVE: To determine the efficacy and tolerability of venlafaxine hydrochloride extended-release (XR) for major depressive disorder (MDD) or dysthymic disorder in persons with chronic SCI. DESIGN, SETTING, AND PARTICIPANTS: Multisite, randomized (1:1), double-blind, placebo-controlled Project to Improve Symptoms and Mood After SCI (PRISMS) trial. All research staff conducting screening, intervention, and outcome procedures were blinded to randomization status. We screened 2536 patients from outpatient clinics at 6 SCI treatment centers in the United States and randomized 133 participants into the trial. Participants were 18 to 64 years old and at least 1 month after SCI, with MDD or dysthymic disorder. Seventy-four percent of participants were male, and participants were on average 40 years old and 11 years after SCI. Forty-seven percent had cervical injuries, 53.4% had American Spinal Injury Association injury severity A (complete injury) SCI, 24.1% had at least 2 prior MDD episodes, and 99.2% had current MDD. Common comorbidities included chronic pain (93.9%), significant anxiety (57.1%), and history of substance dependence (44.4%). INTERVENTIONS: Twelve-week trial of venlafaxine XR vs placebo using a flexible-dose algorithm. MAIN OUTCOMES AND MEASURES: The Hamilton Depression Rating Scale (HAM-D 17-item version and Maier subscale, which focuses on core depression symptoms and excludes somatic symptoms) over 12 weeks. RESULTS: Mixed-effects models revealed a significant difference between the venlafaxine XR and placebo groups in improvement on the Maier subscale from baseline to 12 weeks (treatment effect, 1.6; 95% CI, 0.3-2.9; P = .02) but not on the HAM-D 17-item version (treatment effect, 1.0; 95% CI, -1.4 to 3.4; P = .42). Participants receiving venlafaxine XR reported significantly less SCI-related disability on the Sheehan Disability Scale at 12 weeks compared with placebo (treatment effect, 4.7; 95% CI, 1.5-7.8; P = .005). Blurred vision was the only significantly more common new or worsening adverse effect in the venlafaxine XR group compared with the placebo group over 12 weeks. CONCLUSIONS AND RELEVANCE: Venlafaxine XR was well tolerated by most patients and an effective antidepressant for decreasing core symptoms of depression and improving SCI-related disability. Further research is needed to determine the optimal treatment and measurement approaches for depression in chronic SCI. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00592384.

RESUMO

OBJECTIVES: To (1) determine the efficacy of venlafaxine XR for the treatment of pain (secondary aim) in individuals with spinal cord injury (SCI) enrolled in a randomized controlled trial (RCT) on the efficacy of venlafaxine XR for major depressive disorder (MDD) (primary aim); and (2) test the hypothesis that venlafaxine XR would be effective for both neuropathic and nociceptive pain. DESIGN: Multisite, double-blind, randomized (1:1) controlled trial with subjects block randomized and stratified by site, lifetime history of substance abuse, and prior history of MDD. SETTING: Six Departments of Physical Medicine and Rehabilitation in university-based medical schools. PARTICIPANTS: Individuals (N=123) with SCI and major depression between 18 and 64 years of age, at least 1 month post-SCI who also reported pain. INTERVENTION: Twelve-week trial of venlafaxine XR versus placebo using a flexible titration schedule. OUTCOME MEASURES: A 0-to-10 numeric rating scale for pain, pain interference items of the Brief Pain Inventory; 30% and 50% responders. RESULTS: The effect of venlafaxine XR on neuropathic pain was similar to that of placebo. However venlafaxine XR resulted in statistically significant and clinically meaningful reductions in nociceptive pain site intensity and interference even after controlling for anxiety, depression, and multiple pain sites within the same individual. For those who achieved a minimally effective dose of venlafaxine XR, some additional evidence of effectiveness was noted for those with mixed (both neuropathic and nociceptive) pain sites. CONCLUSIONS: Venlafaxine XR could complement current medications and procedures for treating pain after SCI and MDD that has nociceptive features. Its usefulness for treating central neuropathic pain is likely to be limited. Research is needed to replicate these findings and determine whether the antinociceptive effect of venlafaxine XR generalizes to persons with SCI pain without MDD.

RESUMO

Patients in psychiatric crisis often lack connection to community resources and present to emergency departments (EDs) for care. A transitional psychiatry clinic (TPC) bridged patients after ED visit. These retrospective chart review data of 390 patients were analyzed by ANOVA, logistic regression and survival analysis. Predictors of ED return included psychosis, personality disorder and increased number of prior ED visits. Longer wait for the TPC was associated strongly with non-attendance. TPC appointment within 3 days was associated with significantly longer time in the community without ED presentation. Rapid follow-up after ED visits increased attendance at aftercare and lengthens community tenure.

RESUMO

BACKGROUND: Although placebo-control clinical trials that withhold effective treatments can be permissible, how best to inform participants of the placebo design has received little attention. AIMS: To determine the effect of disclosing quantitative outcome estimates of individual treatment v. entering placebo-control randomised control trial (RCT) on willingness to enrol in such an RCT. METHOD: We randomised 278 adult patients at a depression clinic to receive standard disclosure (n = 129) or enhanced (n = 149) quantitative outcome estimates (based on decision analysis) of individual treatment v. RCT, and assessed their willingness to enrol in the RCT. RESULTS: A greater proportion of those in the standard arm preferred enrolling in RCT (41.3% v. 23.8%, P = 0.002). Those in the standard arm preferred RCT more for direct benefit than altruism reasons, whereas the opposite was true in the enhanced arm. CONCLUSIONS: Disclosing the quantitative outcome implications of placebos may select for fewer but more altruistic participants.

RESUMO

OBJECTIVE: This exploratory study examines the concurrent validity for mapping symptoms of suicidal ideation, self-harm, and suicidal behavior as recorded on the InterSePT Scale for Suicidal Thinking-Plus, the Sheehan-Suicidality Tracking Scale (clinician- and patient-rated and reconciled patient/clinician versions), and the Columbia-Suicide Severity Rating Scale to the 11 United States Food and Drug Administration-Classification Algorithm of Suicide Assessment (September 2012) categories. METHOD: Forty subjects with varying degrees of suicidal ideation and behavior severity (from not present to extremely severe) were recruited from inpatient, outpatient, and emergency room settings. Each patient was interviewed using all three scales (InterSePT Scale for Suicidal Thinking-Plus, the Sheehan-Suicidality Tracking Scale, and the Columbia-Suicide Severity Rating Scale) on the same day. The scales were administered in a random sequence by three independent raters who were blind to the ratings on the other scales. RESULTS: The Sheehan-Suicidality Tracking Scale and the InterSePT Scale for Suicidal Thinking-Plus show acceptable agreement with the Columbia-Suicide Severity Rating Scale in detecting the presence or absence of the 2012 Food and Drug Administration-Classification Algorithm of Suicide Assessment categories 1, 5, 6, 10, and 11 (passive ideation; active ideation with method, intent, and plan; completed suicide; preparatory actions; and self-injurious behavior) but not of categories 2, 3, and 4 (3 other active suicidal ideation combination categories) or to 8 and 9 (aborted and interrupted attempt). Despite the significant disagreement between the Columbia-Suicide Severity Rating Scale on the one side and the InterSePT Scale for Suicidal Thinking-Plus and the Sheehan-Suicidality Tracking Scale on the other in the ability to accurately map to the 2012 Food and Drug Administration-Classification Algorithm of Suicide Assessment categories on some items, there was close agreement between the InterSePT Scale for Suicidal Thinking-Plus and the Sheehan-Suicidality Tracking Scale on these categories. CONCLUSION: The results of this exploratory study invite discussion and debate about the validity of the Columbia-Suicide Severity Rating Scale and its ability to accurately assess key active suicidal ideation categories, since it disagrees so much with the other two standardized scales that agree so closely with each other.

RESUMO

OBJECTIVE: To explore the authors' predictions 1) that hopelessness would positively correlate with suicidal ideation and that impulsivity (either transient urges to self-harm or impulsive acting out) would positively correlate with suicidal behavior, and 2) that the recent or long-standing nature of the traits will have corresponding effects on reported histories of suicidal ideation and behavior. DESIGN: Questionnaire validation trial in which each subject received every measure in counterbalanced fashion. SETTING: Inpatient and outpatient psychiatric settings associated with a medium-sized medical school in the southeastern United States. PARTICIPANTS: Forty-five subjects presenting with varying levels of suicidal ideation and behavior completed measures providing information about their histories of suicidal ideation and behavior, recent feelings of hopelessness, feelings of general hopelessness, recent feelings of difficulty controlling urges to self-harm, and feeling about general levels of impulsivity. MEASUREMENTS: The InterSePT Scale for Suicidal Thinking-Plus, the Sheehan-Suicidality Tracking Scale, the Columbia-Suicide Severity Rating Scale, and six additional questions to assess hopelessness and impulsivity. RESULTS: Recent and trait hopelessness correlated positively with suicidal ideation. Patients who reported any suicide attempt endorsed higher levels of general impulsivity than those who did not report a history of at least one suicide attempt. Those enrolled in the study secondary to a very recent suicide attempt reported more difficulties with recent suicidal impulses. CONCLUSION: Simple measures of hopelessness and impulsivity are associated with suicidal ideation and attempts and may add to determination of suicide risk.
