An integrative systematic review of online resources and interventions for people bereaved by suicide.
Suicide bereavement is frequent in the general population and it can have deleterious consequences on the mental health and social functioning of the bereaved individuals. However, those bereaved can face substantial barriers to receive support, and online resources may improve the accessibility of support. This systematic review aimed at examining the use and benefits of online resources dedicated to people bereaved by suicide and appraising the quality of the research in this field. ⋯ People bereaved by suicide use online resources to seek and share support, share and find information, memorialize their loved one and for meaning-making. Negative effects of online resources are rare. The evidence on the use and benefits of online resources for people bereaved by suicide remains scarce but show encouraging results regarding their positive impact on the mental and psychosocial health of the users.

The fourth wave of the US opioid epidemic and its implications for the rural US: A federal perspective.
The current opioid epidemic in the United States has been characterized as having three waves: prescription opioid use, followed by heroin use, and then use of synthetic opioids (e.g., fentanyl), with early waves affecting a population that was younger, less predominantly male, and more likely to be Caucasian and rural than in past opioid epidemics. A variety of recent data suggest that we have entered a fourth wave which can be characterized as a stimulant/opioid epidemic, with mental illness co-morbidities being more evident than in the past. ⋯ These compound existing issues in addressing the opioid epidemic in rural areas, including the low density of populations and the scarcity of behavioral health resources (e.g., fewer credentialed behavioral health professionals, particularly those able to prescribe Buprenorphine). Considerations for addressing this new wave are discussed, along with the drawbacks of a wave perspective and persistent concerns in confronting drug abuse such as stigma.

Randomized Controlled TrialCumulative vulnerabilities as a potential moderator of response to reduced nicotine content cigarettes.
Risk for smoking increases in a summative manner corresponding to the number of co-occurring vulnerabilities present (cumulative vulnerability). We examined whether cumulative vulnerabilities moderate response to reduced nicotine content cigarettes in a secondary analysis of results from 775 participants in three 12-week randomized clinical trials examining research cigarettes varying in nicotine content (0.4, 2.4, 15.8 mg nicotine/g tobacco). Participants were categorized as having 0-1, 2-3, or ≥ 4 cumulative vulnerabilities. ⋯ The only exception across the other outcomes was on Questionnaire-on-Smoking-Urges Factor-2 ratings for usual-brand cigarettes where cumulative vulnerability, dose, and time interacted (P = 0.007), with craving at the 0.4 and 2.4 mg/g doses decreasing over time, but inconsistently across vulnerability categories. Overall, we saw little evidence that cumulative vulnerabilities moderate response to reduced nicotine content cigarettes suggesting that a policy reducing nicotine content in cigarettes to minimally addictive levels could benefit even highly vulnerable smokers including those residing in rural or other regions with overrepresentation of co-occurring vulnerabilities. Clinicaltrials.gov identifiers: NCT02232737, NCT02250664, NCT02250534.

ReviewSuicide, firearms, and legislation: A review of the Canadian evidence.
Suicide accounts for approximately 4000 deaths a year in Canada, of which about 16% of those are suicide using a firearm. Canada has undertaken legislative efforts to regulate and control firearms, Bill C-51 in 1977 and Bills C-17 and C-68 in 1991 and 1995. Regulatory approaches that decrease the availability of firearms are hypothesized to reduce suicide by firearm however the substitution effect suggests it is possible that people may substitute other methods of suicide in place. ⋯ Six studies examining the effects of Bill C-17 and C-68 revealed a decrease in the rates of suicide by firearms, with a corresponding increase in non-firearms suicide rates and no decrease in overall suicide rates. One study even suggested no associated decrease in firearm suicide rates with an increasing rate of suicide by hanging possibly due to changes in preferences. These results suggest legislation has mixed effects on firearm suicide rates and may not alone reduce overall suicide in Canada.
