Background: Sleep disturbance has been described as a ‘hallmark’ symptom of posttraumatic stress disorder (PTSD). Although there are robust findings of self-reported sleep disturbance in PTSD, evidence of sleep disturbance measured using actigraphy is less certain.

Objective: To conduct a systematic review and meta-analysis to determine whether there are any significant differences between individuals with and without PTSD in actigraphderived sleep measures.

The COVID-19 pandemic, a defining health event of our time, is bringing rapid changes to mental health care across the globe. Although there is extensive disruption to existing practices, the response to the pandemic is presenting opportunities for advancing the field of global mental health (GMH) in low- and middle-income countries (LMICs).

In complex humanitarian emergencies, infants and young children are exposed to a higher risk of malnutrition, morbidity, delayed development and mortality. As shown by earlier research, maternal mental health and capacity for nurturing are of fundamental importance in child health and development.

The Syrian conflict has resulted in the worst humanitarian crisis of the 21st century with millions of people displaced inside Syria or in neighbouring countries. Severe shortages of mental health professionals in the area have created many challenges in addressing the mental health needs of this vulnerable population. In response, the Syrian Tele-Mental Health (STMH) Network was established in June 2014 following evidence gathered through a pilot survey.
