Suicide is a leading cause of premature death among military service members/veterans (SM/Vs). The Interpersonal Theory of Suicide (Joiner, 2007) proposes that higher thwarted belonging, perceived burdensomeness, and acquired capability confer increased risk for suicide. However, no studies have examined the association of sexual dysfunction, a possible component of thwarted belonging and perceived burdensomeness, with suicidal ideation. The present study explored whether sexual dysfunction was associated with suicidal ideation when accounting for mental health, demographic, and military characteristics among female SM/Vs. ⋯ Sexual dysfunction is associated with suicidal ideation, accounting for established mental health, military, and demographic characteristics among female SM/Vs. Efforts to prevent suicidal ideation in female SM/Vs may be enhanced by screening for and treating sexual dysfunction, particularly sexual arousal and satisfaction.

Mindfulness is a trainable skill that may enhance resilience to suicidality among vulnerable groups such as young people. The current study examined whether mindfulness protects against suicidal desire in the face of heightened risk and adversity by increasing zest for life in a sample of university students. ⋯ Findings suggest that mindfulness protects against suicidal desire in conditions of heightened risk and adversity by enhancing one's orientation towards a life worth living. Theories of suicide should consider the dynamic interplay between risk and life-sustaining resilience, while clinicians treating suicidality could use mindfulness strategies to strengthen the desire to (re)engage with life, thereby complementing direct amelioration of suicide risk factors.

Suicide attempts (SA) and non-suicidal self-injury (NSSI) are prevalent in adolescents and important risk factors of suicide death. Both SA and NSSI are associated with multiple psychosocial, behavioral, biological and genetic factors. This study examined similarities and differences in psychological vulnerability and internalizing and externalizing problems between adolescents with SA and NSSI. ⋯ Psychological and behavioral profiles between adolescents with SA and NSSI are similar but are more severe in suicide attempters. The findings highlight the necessity of assessing psychological and behavioral problems for prevention and early intervention of adolescent self-harm.

Randomized Controlled Trial
Persistent antidepressant effect of low-dose ketamine and activation in the supplementary motor area and anterior cingulate cortex in treatment-resistant depression: A randomized control study.
A single low-dose ketamine infusion exhibited a rapid antidepressant effect within 1h. Despite its short biological half-life (approximately 3h), the antidepressant effect of ketamine has been demonstrated to persist for several days. However, changes in brain function responsible for the persistent antidepressant effect of a single low-dose ketamine infusion remain unclear METHODS: Twenty-four patients with treatment-resistant depression (TRD) were randomized into three groups according to the treatment received: 0.5mg/kg ketamine, 0.2mg/kg ketamine, and normal saline infusion. ⋯ The increase in the SUV in the dACC was negatively correlated with depressive symptoms at 1day after ketamine infusion DISCUSSION: The persistent antidepressant effect of a 0.5mg/kg ketamine infusion may be mediated by increased activation in the SMA and dACC. The higher increase in dACC activation was related to the reduction in depressive symptoms after ketamine infusion. A 0.5mg/kg ketamine infusion facilitated the glutamatergic neurotransmission in the SMA and dACC, which may be responsible for the persistent antidepressant effect of ketamine much beyond its half-life.

Randomized Controlled Trial
Effectiveness of assertive case management on repeat self-harm in patients admitted for suicide attempt: Findings from ACTION-J study.
Self-harm is an important risk factor for subsequent suicide and repetition of self-harm, and a common cause of emergency department presentations. However, there still remains limited evidence on intervention in emergency department settings for individuals who self-harm. ⋯ The present study showed that assertive case management following emergency admission for a suicide attempt reduced the incident rate of repeat overall self-harm.
