Resumen Los Productos de Tabaco Calentado (PTC) son nuevos dispositivos de consumo de tabaco que se presentan como un producto de reducción del daño. El más difundido es IQOS de Philip Morris. En el aerosol de IQOS se detectan sustancias tóxicas en menor cantidad y concentración que las detectadas en el humo del cigarrillo convencional, a excepción de algunas. Estas sustancias son capaces de producir enfermedad, con alteración de las células del epitelio bronquial y del endotelio vascular y podría producir nuevos daños, como hepato-toxicidad. La cantidad de nicotina de IQOS es muy similar a los cigarrillos convencionales, por lo que es tan adictivo como el cigarrillo normal. La concentración de sustancias tóxicas emitidas al medio ambiente es menor que las del cigarrillo convencional, pero hay riesgo para la salud de los no fumadores expuestos. La mayoría de las personas usan los PTC como complemento a los cigarrillos convencionales, no como alternativa, transformándose en fumadores duales. IQOS puede crear nuevas generaciones adictas a la nicotina, además de renormalizar el consumo de tabaco en la sociedad. Muchas Sociedades Médicas de Enfermedades Respiratorias en el mundo se han manifestado en contra del uso de los PTC, y han propuesto que deben regirse bajo las mismas políticas regulatorias que se aplican a todos los productos de tabaco, en línea con lo establecido por el Convenio Marco de Control del Tabaco de la OMS. Heated Tobacco Products (HTP) are new tobacco consumption devices that are presented as a harm reduction product. The most widespread is IQOS by Philip Morris. In the IQOS aerosol, toxic substances are detected in a smaller amount and concentration than those detected in conventional cigarettes, with the exception of some of them. These substances are able of inducing disease. They could modify bronchial epithelial cells and vascular endothelium and could cause additional damages, such as hepatotoxicity The amount of nicotine in IQOS is very similar to conventional cigarettes, so it is as addictive as a normal cigarette. The concentration of toxic substances emitted to the environment is lower than those of conventional cigarettes, but there is a health's risk of exposed non-smokers. Most people use HTP as a complement to conventional cigarettes, not as an alternative, becoming dual smokers. IQOS can create new generations addicted to nicotine, in addition to renormalize the tobacco's use in society. Many Medical Societies of Respiratory Diseases around the world have manifested against the use of HTP, and have proposed that they should be subject to the same regulatory policies that applied to all tobacco products, in line with the WHO Framework Convention on Tobacco Control.

El objetivo de este artículo es presentar una actualización de los fundamentos teóricos y metodológicos de la consejería y la evidencia sobre su eficacia, relacionándola con la práctica de los equipos de salud y analizando los desafíos futuros. Se describen las bases teóricas, las orientaciones de política del Ministerio de Salud de Chile, las estrategias recomendadas a nivel internacional y los aportes de los participantes de un programa de capacitación realizado por el INTA con 312 profesionales (nutricionistas, kinesiólogos y odontólogos en su mayoría). Se presenta el análisis de las condiciones en la Atención Primaria de Salud para implementar la consejería en alimentación, actividad física y tabaco en forma sistemática. Se discute la necesidad de adoptar medidas para el mejoramiento de la práctica y su contribución a un abordaje preventivo de los graves problemas de sedentarismo, obesidad y tabaquismo en la población chilena. The aim of this article was to present an update of the theorical and methodological foundations of counseling and evidence of their effectiveness, relating to the practice of health teams and analyzing future challenges. It is described, the theorical basis, the policy directions of the Chilean Ministry of Health, the international recommended strategies and the contributions of the participants in a training program conducted by INTA with 312 professionals (nutritionists, physiotherapists and dentists mostly). The analysis of the conditions in the Primary Health Care, to implement systematically nutrition, physical activity and tobacco counseling is presented. The need to improve the practice and its contribution to a preventive approach to serious problems of physical inactivity, obesity and smoking in the Chilean population is discussed.

Enmarcado en el objetivo de promover la humanización de la salud en el Instituto Nacional del Tórax, este trabajo se propuso realizar un estudio descriptivo exploratorio de tipo cualitativo con la finalidad de conocer las funciones, percepciones, valores y actitudes del personal de la Unidad Médico Quirúrgico Respiratorio ante los pacientes que viven su proceso de muerte en el hospital. Nos interesaba también, identificar las fortalezas, carencias y necesidades sentidas por el equipo de trabajo en la atención de estos pacientes terminales y en el tratamiento que se realiza con el cuerpo del fallecido. Esta información permitirá implementar medidas que ayuden a dignificar la muerte en esta Unidad. Se realizaron un total de 26 entrevistas semiestructuradas, correspondientes a un 65% de los funcionarios que laboran en esta Unidad. Los participantes califican su trabajo como "bueno" especialmente en el control de síntomas físicos del paciente y atención a la familia. Reconocen sin embargo, que hay otras necesidades, especialmente las psicológicas y espirituales que no se atienden con excelencia, como consecuencia de la escasa preparación recibida para enfrentar y resolver situaciones de alto contenido emocional y establecer una comunicación terapéutica con el paciente. In order to promote the humanization of health at the National Institute of Thorax, this work is proposed to make a descriptive and exploratory study of qualitative type with the intention of knowing the functions, perceptions, values and attitudes of the staff of the Respiratory Medical Surgical Unit to faced of the patients who live their process of death in hospital. We are also interested in to identifying strengths, weaknesses and needs felt by the team in caring for these terminal ill patients and the treatment use with the body of the deceased. This information will implement measures that will help to dignify the death in this Unit. It is based on 26 interviews (65%) of the staff who work in this unit. Interviewees described her/his work as "good" especially in the control of physical symptoms of the patient and family care issues. They admit, however, there are other needs, especially the psychological and spiritual, that they not serve very well. This is the result of a poor training received to resolve high emotional situations and to establish a therapeutic communication with the patient.

Background: Smoking is the main risk factor for Chronic Obstructive Pulmonary Disease (COPD), an important cause of morbidity and mortality. Aim: To estimate smoking attributable risk and population attributable risk in COPD patients attended in Public Health Services of Santiago. Materials and methods: A case control study matched by sex and age was carried out. Crude and adjusted attributable risks as well as population attributable risk were estimated, controlled by potential confounders and by interaction variables. Results: Mean ages for cases and controls were 68 and 67 years respectively. When compared to the control group, COPD patients had a higher smoking prevalence (at least 100 cigarettes in their life span: 89.7% vs 60.3%; p

Se realizó una revisión de los estudios nacionales e internacionales sobre los efectos del humo de tabaco ambiental en la salud de los fumadores pasivos. El humo de tabaco ambiental está conformado por más de 4.000 sustancias químicas, las que difieren cuali y cuantitativamente al estar presentes en la corriente principal o en la lateral. Los no fumadores expuestos presentan un aumento de morbi-mortalidad por enfermedad cardiovascular, incluso con estudios con biomarcadores como cotinina. Además los fumadores pasivos tienen un riesgo aumentado de presentar cáncer de pulmón, de senos paranasales y mama. En niños existe un mayor número de síntomas respiratorios agudos y crónicos, infecciones respiratorias bajas, otitis media y síndrome de muerte súbita infantil. El humo de tabaco ambiental favorece la inducción y exacerbación de asma bronquial en niños y adultos. En la salud reproductiva, disminuye la edad de aparición de la menopausia y produce desórdenes menstruales. Los recién nacidos hijos de madres fumadoras pasivas tienen mayor probabilidad de nacer con bajo peso o de ser pequeños para la edad gestacional. La evidencia científica internacional debe contribuir a que los países tomen medidas para proteger la salud de los no fumadores

Background: Worldwide, smoking is the main avoidable cause of death among adults. Aim: To study smoking habits among health care workers in Chile. Material and methods: A national survey about smoking among subjects working in the Chilean Ministry of Health. An anonymous and self administered enquiry was used. Results: The enquiry was answered by 20,848 employees, corresponding to 58% of the total universe of workers. There was an overall prevalence of smoking of 40.7%. Sixty four percent of smokers did it daily and their mean consumption was 7 cigarettes per day. Smoking was more common among men than women (43 and 39.6%, respectively). Also, nicotine addiction was also more common among men (16.5 and 11.7%, respectively). The prevalence of smoking decreased along with age. Journalists, guards, students and paramedics had the higher prevalence of smoking. Physicians, teachers and nutritionists had the lower prevalence. Although physicians had the lower frequency of smoking, they had the higher prevalence of nicotine addiction. Forty five percent of smokers were interested in therapies to quit, 69% did not allow smoking at home and 89% agreed with smoking restrictions in work places. Conclusions: The prevalence of smoking among health care workers is similar to that of the general population in Chile (Rev Méd Chile 2004; 134: 223-32)
