Consensus Document on Medical Faculty Education on the Treatment of Smoking. / Documento de consenso sobre la docencia del tabaquismo en las facultades de Medicina.

We report the results of a consensus reached by an expert group of representatives from different medical societies in Latin America on the objectives, competencies (knowledge, and skills), content, and duration of smoking cessation education in Latin American medical schools. The document discusses the following aspects: epidemiology, nicotine dependence, factors for initiation and maintenance of tobacco use, smoking-related disorders, diagnosis, minimal intervention, non-pharmacological and pharmacological interventions for smoking cessation, and prevention of smoking.

Prognostic Value of Frequent Exacerbations in Bronchiectasis: The Relationship With Disease Severity.

INTRODUCTION: Bronchiectasis is a very heterogeneous disease but some homogeneous groups with similar clinical characteristics and prognosis have been identified. Exacerbations have been shown to have a negative impact on the natural history of bronchiectasis. The objective of this study was to identify the definition and characteristics of the "frequent exacerbator patient" with the best prognostic value and its relationship with the severity of bronchiectasis. METHODS: A historical cohort of 651 patients diagnosed with bronchiectasis was included. They had all received 5 years of follow-up since their radiological diagnosis. Exacerbation was defined as a worsening of the symptoms derived from bronchiectasis that required antibiotic treatment. The main outcome was all-cause mortality at the end of follow-up. RESULTS: The mean age was 48.2 (16) years (32.9% males). 39.8% had chronic infection by Pseudomonas aeruginosa. Mean BSI, FACED, and E-FACED were 7 (4.12), 2.36 (1.68), and 2.89 (2.03), respectively. There were 95 deaths during follow-up. The definition of the "frequent exacerbator patient" that presented the greatest predictive power for mortality was based on at least two exacerbations/year or one hospitalization/year (23.3% of patients; AUC-ROC: 0.75 [95% CI: 0.69-0.81]). Its predictive power was independent of the patient's initial severity. The clinical characteristics of the frequent exacerbator patient according to this definition varied according to the initial severity of bronchiectasis, presence of systemic inflammation, and treatment. CONCLUSIONS: The combination of two exacerbations or one hospitalization per year is the definition of frequent exacerbator patient that has the best predictive value of mortality independent of the initial severity of bronchiectasis.

Latin America validation of FACED score in patients with bronchiectasis: an analysis of six cohorts.

BACKGROUND: The FACED score is an easy-to-use multidimensional grading system that has demonstrated an excellent prognostic value for mortality in patients with bronchiectasis. A Spanish group developed the score but no multicenter international validation has yet been published. METHODS: Retrospective and multicenter study conducted in six historical cohorts of patients from Latin America including 651 patients with bronchiectasis. Clinical, microbiological, functional, and radiological variables were collected, following the same criteria used in the original FACED score study. The vital status of all patients was determined in the fifth year of follow-up. The area under ROC curve (AUC-ROC) was used to calculate the predictive power of the FACED score for all-cause and respiratory deaths and both number and severity of exacerbations. The discriminatory power to divide patients into three groups of increasing severity was also analyzed. RESULTS: Mean (SD) age of 48.2 (16), 32.9% of males. The mean FACED score was 2.35 (1.68). During the follow up, 95 patients (14.6%) died (66% from respiratory causes). The AUC ROC to predict all-cause and respiratory mortality were 0.81 (95% CI: 0.77 to 0.85) 0.84 (95% CI: 0.80 to 0.88) respectively, and 0.82 (95% CI: 078-0.87) for at least one hospitalization per year. The division into three score groups separated bronchiectasis into distinct mortality groups (mild: 3.7%; moderate: 20.7% and severe: 48.5% mortality; p < 0.001). CONCLUSIONS: The FACED score was confirmed as an excellent predictor of all-cause and respiratory mortality and severe exacerbations, as well as having excellent discriminative capacity for different degrees of severity in various bronchiectasis populations.
