Differences in firearm suicides by residential location in Texas, 2006-2015

This study used Texas state vital statistics records, 2006–2015, to examine firearm use rates among 28,010 suicide decedents by residential location (urbanized vs. all others). Firearms were responsible for 44% of all teenage suicides and 76–90% and 50–60% of suicides of men and women aged 60 + years, respectively, and firearm use rates remained steady for both […]

Acute alcohol co-ingestion and hospital-treated deliberate self-poisoning: Is there an effect on subsequent self-harm?

The aim of this study was to determine the relationship between alcohol co-ingestion in an index deliberate self-poisoning (DSP) episode with repeated DSP and subsequent suicide. A retrospective cohort study was conducted involving 5,669 consecutive index presentations to a toxicology service following DSP between January 1, 1996, and October 31, 2010.

Looking back on self-poisoning: The relationship between depressed mood and reporting of suicidal intent in people who deliberately self-poison.

Lifetime worst-point suicidality is associated with risk of subsequent death by suicide. Yet little is known about how people who deliberately self-poison (DSP) change their appraisal of suicidal intent of a single DSP episode over time. We assessed whether suicidal intent for a single index episode of DSP changed over time and factors associated with […]

Is there a relationship between suicidal intent and lethality in deliberate self-poisoning?

The relationship between suicidal intent and lethality of deliberate self-poisoning (DSP) episodes and their associations with suicide have yielded contradictory findings. The aims of this study were to investigate the association between patients’ suicidal intent and independently rated lethality of DSP episodes, and whether the association changes over time. Eighty-nine DSP patients were investigated longitudinally. Self-reported suicidal […]

Is tetraethyl lead poison affecting contemporary indigenous suicides in Ontario, Canada?

Highlights •Lead (Pb) poison levels where high among the Indigenous population of Northwestern Ontario prior to the outbreak of a suicide epidemic in the area. •Pb contributes to an overexpression of the amyloid-β protein precursor (AβPP) and amyloid-β (Aβ) which contribute to enhanced pathologic neurodegeneration. •Pb causes a down-regulation (4-fold) of the 5-hydroxytryptamine 1B receptor […]

Postcards in Persia: A twelve to twenty-four month follow-up of a randomized controlled trial for hospital-treated deliberate self-poisoning.

This study reports the outcomes, during follow-up, of a low-cost postcard intervention in a Randomized Control Trial of hospital-treated self-poisoning (n = 2300).
