[Consultations to Emergency Departments for acute psychosis associated with illycit drugs use in Spain (REDUrHE Registry)].

Objective: Mental health problems are increasing in Spain, and those related to drug use are a preventable aspect of public health. In Spain there are few studies on the incidence and characteristics of acute psychosis due to illegal drug use, especially at national and multicenter level, reason that motivated this paper.

Rationale and Design of the Impact of Air Pollution Due to DESERT Dust in Patients with HEART Failure (DESERT HEART).

Aims: The main objective of this study is to determine whether exposure to Saharan dust causes airway inflammation and oxidative stress in patients with stable chronic heart failure (HF) and a left ventricular ejection fraction of less than 40%.

Methods: A longitudinal study design is used, involving the inclusion of 40 patients with stable chronic HF and a left ventricular ejection fraction of less than 40%. Four sputum samplings will be taken from each patient, with one sampling taken each week over four consecutive weeks.

Differences in clinical signs and severity of intoxication due to street drugs in adolescents and young adults treated in emergency departments.

Objectives: To determine whether symptoms and levels of severity of intoxication from street drugs differ between adolescents and young adults who come to hospital emergency departments for treatment.

Material And Methods: We studied a consecutive cohort of adolescents (aged 12-17 years) and young adults (aged 18-30 years) who were treated in 11 hospital emergency departments belonging to the Drug Abuse Network of Spanish Hospital Emergency Departments (REDURHE). Sociodemographic and clinical characteristics and level of severity were recorded for comparison between between adolescents and young adults, adjusted for sex, alcohol co-ingestion, and type of drug used.
