..CONCLUSIONS: The political economy of suicide by charcoal-burning illustrated how historical, socio-economic and cultural forces shaped the lived experience that preceded suicide...

..6 per 100,000. The most significant increase was found among the older adults aged 65 or above...

..By examining a series of 17 suicide cases with evidence of pathological gambling prior to death, we sought to generate hypotheses for further study of this under-researched but rapidly-increasing worldwide public health problem...

..The short-term effect of celebrity suicide on the overall suicide rate is widely known, but long-term effects remain unclear...

..Suicide prevention strategy may have to target potential subgroups with specific approaches...

..This study also demonstrated its predictive validity by examining sensitivity and specificity in identifying subsequent suicidality. A 4-item short version of ASIQ was also developed...

..Present data suggest that reasons for leaving suicide notes may have changed over the 8 years from 1992 to 2000...

..Despite increasing concern over the potential adverse effects of excessive internet use, especially in young people, there is some debate over its definition, magnitude and discriminant validity...
