Comparative Study
Residential exposure to urban traffic is associated with the poorer neurobehavioral health of Ecuadorian schoolchildren.
We investigated whether chronic traffic-generated air pollution containing fine and ultrafine particulate matter is associated with reduced neurobehavioral performance and behavioral dysfunction in urban Ecuadorian schoolchildren. Also, we examined the effect of child hemoglobin and sociodemographic risk factors on these neurocognitive outcomes. ⋯ The study findings suggest that children living within 100 m of heavy traffic appear to experience subtle neurobehavioral deficits that may result from fine and ultrafine particulate matter exposure.

Phthalate have been detected widely in the environment; while several studies have indicated that prenatal phthalate exposure has adverse effects on neurodevelopment, the results were inconsistent. ⋯ Di(2-ethylhexyl) phthalate, dibutyl phthalate, butyl-benzyl phthalate and di-ethyl phthalate exposure during pregnancy was associated with lower cognitive scores and worse behavior in offspring, and sex-specific effects on cognitive, psychomotor, and behavioral development were identified, especially the impact of phthalate exposure on neurobehavior in boys.

Seizures as a complication of recreational drug use: Analysis of the Euro-DEN Plus data-set.
Seizures are a recognized and potentially serious complication of recreational drug use. This study examined a large international data set of presentations to Emergency Departments with acute recreational drug toxicity, the European Drug Emergencies Plus (Euro-DEN Plus) Network, to compare presentations with and without seizures and estimate incidence and associated drugs. Amongst 23,947 presentations between January 2014 and December 2017, there were 1013 (4.2%) with reported seizures. ⋯ Other drugs were associated with a lower seizure incidence, including heroin (OR 0.46, 95% CI 0.35-0.61), clonazepam (OR 0.22, 95% CI 0.06-0.91), and cannabis (OR 0.65, 95% CI 0.50-0.86). This substantiates observations that the synthetic cannabinoids as a group of novel psychoactive substances are clinically different in consequence of intoxication than cannabis, and that individuals who suffer a seizure in the context of recreational drug intoxication are likely to have worse outcomes overall. Utilising this information of what substances have a greater risk of seizures, could provide tailored harm reduction and education strategies to users to reduce the risk of seizures and their associated complications.
