Do adolescents who use stimulants have a different personality?

El consumo de psicoestimulantes tiene una especial importancia en nuestro medio por su notable incremento entre los más jóvenes. El objetivo del presente estudio es determinar si hay diferencias entre menores de edad consumidores y no consumidores de psicoestimulantes (cocaína y éxtasis) en función de las características de personalidad evaluadas con el MACI. La muestra está formada por 398 jóvenes entre 14 y 17 años que fueron seleccionados con un muestreo aleatorio en los domicilios de los entrevistados y en lugares de ocio y diversión. Los resultados confirman la existencia de importantes diferencias en las características de personalidad de ambos. Los jóvenes que han consumido psicoestimulantes se caracterizan por tener los prototipos de personalidad Rebelde, Rudo, Oposicionista y Tendencia límiteStimulant consumption is especially important in our context because its use has greatly increased in recent years. The aim of the present study is to analyze the differences between stimulant users and nonusers (under 18 years old) in personality characteristics assessed with the MACI. The sample comprises 398 youths between 14 and 17 years old who were selected through random sampling in their homes or in recreational night spots. Results show important differences in personality features between stimulant users and nonusers. Stimulant users are characterized by having unruly, forceful, oppositional and borderline-tendency personality prototypesS

Cost of Hospitalizations due to Exacerbation in Patients with Non-Cystic Fibrosis Bronchiectasis.

Knowing the cost of hospitalizations for exacerbation in bronchiectasis patients is essential to perform cost-effectiveness studies of treatments that aim to reduce exacerbations in these patients. To find out the mean cost of hospitalizations due to exacerbations in bronchiectasis patients, and to identify factors associated with higher costs. Prospective, observational, multicenter study in adult bronchiectasis patients hospitalized due to exacerbation. All expenses from the patients' arrival at hospital to their discharge were calculated: diagnostic tests, treatments, transferals, home hospitalization, admission to convalescence centers, and hospitals' structural costs for each patient (each hospital's tariff for emergencies and 70% of the price of a bed for each day in a hospital ward). A total of 222 patients (52.7% men, mean age 71.8 years) admitted to 29 hospitals were included. Adding together all the expenses, the mean cost of the hospitalization was EUR 5,284.7, most of which correspond to the hospital ward (86.9%), and particularly to the hospitals' structural costs. The adjusted multivariate analysis showed that chronic bronchial infection by Pseudomonas aeruginosa, days spent in the hospital, and completing the treatment with home hospitalization were factors independently associated with a higher overall cost of the hospitalization. The mean cost of a hospitalization due to bronchiectasis exacerbation obtained from the individual data of each episode is higher than the cost per process calculated by the health authorities. The most determining factor of a higher cost is chronic bronchial infection due to P. aeruginosa, which leads to a longer hospital stay and the use of home hospitalization

The role of bronchoscopy in patients with sars-cov-2 pneumonia

Altres ajuts: Sociedad Española de Neumología y Cirugía Torácica (SEPAR, PII 2020).Background The role of bronchoscopy in coronavirus disease 2019 (COVID-19) is a matter of debate. Patients and methods This observational multicentre study aimed to analyse the prognostic impact of bronchoscopic findings in a consecutive cohort of patients with suspected or confirmed COVID-19. Patients were enrolled at 17 hospitals from February to June 2020. Predictors of in-hospital mortality were assessed by multivariate logistic regression. Results A total of 1027 bronchoscopies were performed in 515 patients (age 61.5±11.2 years; 73% men), stratified into a clinical suspicion cohort (n=30) and a COVID-19 confirmed cohort (n=485). In the clinical suspicion cohort, the diagnostic yield was 36.7%. In the COVID-19 confirmed cohort, bronchoscopies were predominantly performed in the intensive care unit (n=961; 96.4%) and major indications were: difficult mechanical ventilation (43.7%), mucus plugs (39%) and persistence of radiological infiltrates (23.4%). 147 bronchoscopies were performed to rule out superinfection, and diagnostic yield was 42.9%. There were abnormalities in 91.6% of bronchoscopies, the most frequent being mucus secretions (82.4%), haematic secretions (17.7%), mucus plugs (17.6%), and diffuse mucosal hyperaemia (11.4%). The independent predictors of in-hospital mortality were: older age (OR 1.06; p<0.001), mucus plugs as indication for bronchoscopy (OR 1.60; p=0.041), absence of mucosal hyperaemia (OR 0.49; p=0.041) and the presence of haematic secretions (OR 1.79; p=0.032). Conclusion Bronchoscopy may be indicated in carefully selected patients with COVID-19 to rule out superinfection and solve complications related to mechanical ventilation. The presence of haematic secretions in the distal bronchial tract may be considered a poor prognostic feature in COVID-19
