PURPOSE: The aim was to assess the associations of antibullying U.S. state statutes that enumerate sexual orientation with exposure to bullying and other stressors and with suicidal ideation and suicide attempts in sexual minority and non sexual minority youth. METHODS: We analyzed data from the 2015 national school-based Youth Risk Behavior Survey, representative of 9th through 12th grade students attending public and private schools in the United States. We reviewed each states antibullying statutes and classified them on enumeration. RESULTS: Antibullying state laws that enumerate sexual orientation were associated with lower risk for suicide attempts and serious attempts requiring medical attention and lower risk for forced sexual intercourse. They were also associated with feeling safe at school or on the way to or from school. Results did not differ by sexual orientation. CONCLUSIONS: Enumeration of sexual orientation was associated with reduced stressors and suicide attempts, but it is insufficient to remove significant disparities based on sexual orientation. Additional policies and practices are required to address persistent sexual orientation disparities in exposure to bullying and suicidal behavior.

Objectives

Nearly half of all men who die by suicide visit a primary care clinician (PCC) in the month before death, yet few disclose suicide thoughts. We solicited stakeholders' views to guide development of a tailored multimedia program to activate middle-aged men experiencing suicide thoughts to engage with PCCs.

Methods

We conducted semi-structured interviews with 44 adults self-identifying as: suicide attempt survivor; family member/loved one of person(s) who attempted or died by suicide; PCC; non-PCC office staff; health administrator; and/or prevention advocate. We coded recorded interview transcripts and identified relevant themes using grounded theory.

Results

Two thematic groupings emerged, informing program design: structure and delivery (including belief the program could be effective and desire for use of plain language and media over text); and informational and motivational content (including concerns about PCC preparedness; fear that disclosing suicide thoughts would necessitate hospitalization; and influence of male identity and masculinity, respectively, in care-seeking for and interpreting suicide thoughts).

Conclusion

Stakeholder input informed the design of a primary care tailored multimedia suicide prevention tool.

Practice implications

In revealing a previously unreported barrier to disclosing suicide thoughts to PCCs (fear of hospitalization), and underscoring known barriers, the findings may suggest additional suicide prevention approaches.

Purpose

Middle-aged men are at high risk of suicide. While about half of those who kill themselves visit a primary care clinician (PCC) shortly before death, in current practice, few spontaneously disclose their thoughts of suicide during the visits, and PCCs seldom inquire about such thoughts. In a randomized controlled trial, we examined the effect of a tailored interactive computer program designed to encourage middle-aged men's discussion of suicide with PCCs.

Methods

We recruited men 35-74 years old reporting recent (within 4 weeks) active suicide thoughts from the panels of 42 PCCs (the unit of randomization) in eight offices within a single California health system. In the office before a visit, men viewed the intervention corresponding to their PCC's random group assignment: Men and Providers Preventing Suicide (MAPS) (20 PCCs), providing tailored multimedia promoting discussion of suicide thoughts, or control (22 PCCs), composed of a sleep hygiene video plus brief non-tailored text encouraging discussion of suicide thoughts. Logistic regressions, adjusting for patient nesting within physicians, examined MAPS' effect on patient-reported suicide discussion in the subsequent office visit.

Results

Sixteen of the randomized PCCs had no patients enroll in the trial. From the panels of the remaining 26 PCCs (12 MAPS, 14 control), 48 men (MAPS 21, control 27) were enrolled (a mean of 1.8 (range 1-5) per PCC), with a mean age of 55.9 years (SD 11.4). Suicide discussion was more likely among MAPS patients (15/21 [65%]) than controls (8/27 [35%]). Logistic regression showed men viewing MAPS were more likely than controls to discuss suicide with their PCC (OR 5.91, 95% CI 1.59-21.94; P = 0.008; nesting-adjusted predicted effect 71% vs. 30%).

Conclusions

In addressing barriers to discussing suicide, the tailored MAPS program activated middle-aged men with active suicide thoughts to engage with PCCs around this customarily taboo topic.

RIPK1 is a key regulator of innate immune signalling pathways. To ensure an optimal inflammatory response, RIPK1 is regulated post-translationally by well-characterized ubiquitylation and phosphorylation events, as well as by caspase-8-mediated cleavage^1-7. The physiological relevance of this cleavage event remains unclear, although it is thought to inhibit activation of RIPK3 and necroptosis⁸. Here we show that the heterozygous missense mutations D324N, D324H and D324Y prevent caspase cleavage of RIPK1 in humans and result in an early-onset periodic fever syndrome and severe intermittent lymphadenopathy-a condition we term 'cleavage-resistant RIPK1-induced autoinflammatory syndrome'. To define the mechanism for this disease, we generated a cleavage-resistant Ripk1^D325A mutant mouse strain. Whereas Ripk1^-/- mice died postnatally from systemic inflammation, Ripk1^D325A/D325A mice died during embryogenesis. Embryonic lethality was completely prevented by the combined loss of Casp8 and Ripk3, but not by loss of Ripk3 or Mlkl alone. Loss of RIPK1 kinase activity also prevented Ripk1^D325A/D325A embryonic lethality, although the mice died before weaning from multi-organ inflammation in a RIPK3-dependent manner. Consistently, Ripk1^D325A/D325A and Ripk1^D325A/+ cells were hypersensitive to RIPK3-dependent TNF-induced apoptosis and necroptosis. Heterozygous Ripk1^D325A/+ mice were viable and grossly normal, but were hyper-responsive to inflammatory stimuli in vivo. Our results demonstrate the importance of caspase-mediated RIPK1 cleavage during embryonic development and show that caspase cleavage of RIPK1 not only inhibits necroptosis but also maintains inflammatory homeostasis throughout life.
