Analysis of Google Trends to monitor new psychoactive substance. Is there an added value?

The past decade has seen an increase in the development and availability of a broad category of drugs, known as new psychoactive substances (NPS). NPS are challenging for public health authorities, therefore the two major drug monitoring bodies - the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) and the United Nations Office on Drugs and Crime (UNODC) - have implemented the EU Early Warning System (EWS) and Early Warning Advisory (EWA), respectively. While these monitoring systems are informative, it is difficult to keep up with the constant and rapid developmental rate of NPS.

Prevalence and correlates of depression among caregivers of children living with HIV in Ghana: findings from the Sankofa pediatric disclosure study.

Prior studies show an association between caregiver depression and child health outcomes. There has been little examination of depression among caregivers of HIV-infected children in sub-Saharan countries where pediatric HIV is concentrated. Using baseline data collected in the pediatric HIV disclosure intervention trial, Sankofa, we examined the prevalence and factors associated with depression among caregivers (N = 446) of children infected with HIV in Ghana.

Emergence, Diversity, and Control of New Psychoactive Substances: A Global Perspective.

The phenomenon of new psychoactive substances (NPS), which came to the attention of the wider international community at the beginning of the 2010s, has been unprecedented in terms of the sheer number of substances, their rate of emergence, chemical diversity, and range of pharmacological effects. In particular, the chemical diversity has been a challenge to promoting a better understanding of the NPS market - a fundamental requirement for effective policy decisions and interventions. This manuscript highlights the significant chemical diversity of NPS and describes an alternative, complementary, and pragmatic classification based on pharmacological effects, which aligns NPS to traditional controlled drugs and enhances understanding of the phenomenon.
