Suicide is one of the major causes of death in young people, in whom suicide can occur in clusters. In this Review, we have investigated definitions and epidemiology of such clusters, the factors associated with them, mechanisms by which they occur, and means of intervening and preventing them. Clustering of suicidal behaviour is more common in young people (<25 years) than adults. Suicide clusters can occur as a greater number of episodes than expected at a specific location, including in institutions (eg, schools, universities, psychiatric units, and youth offender units). 

In late 2018, motivated (and intrigued) by the scale of one of the largest and long-standing humanitarian crises in history, we embarked on two separate but related journeys to the island of Lesvos to work with unaccompanied refugee and asylum-seeking minors and to link in with NGOs working in the region.

Our study systematically reviews articles about the prevalence of Post-traumatic Stress Disorder (PTSD) among children and adolescents, aiming to evaluate its prevalence after earthquakes and floods.Three databases (PubMed, Scopus, and Web of Science) were searched for articles published from 1981 to 2019 containing information on PTSD prevalence among survivors of earthquakes and floods. Articles with insufficient data on the prevalence of PTSD or without any available full-text were excluded.

Families provide children with crucial surroundings of social support, acknowledgment, and hope, creating a protective shield. When a family is confronted with adversities and long-lasting stress and faces adjustment difficulties, familial support may become inadequate, and the family environment is a source of additional stress for the child. It is therefore important to find ways to preserve and strengthen family support in times of difficulties.
