RESUMO
Las enfermedades respiratorias crónicas, se incrementan a nivel mundial, destacándose EPOC, fibrosis pulmonar, bronquiectasia y sumándose la condición post COVID-19 asociadas a las vías respiratorias. Objetivo. Determinar los efectos de la rehabilitación respiratoria con cánula nasal de alto flujo en pacientes con enfermedades respiratorias crónicas. Material y método. Estudio realizado en un hospital militar peruano a una muestra constituida por 115 pacientes, quienes ingresaron a un programa de Rehabilitación Respiratoria de 12 semanas con la asistencia de la Cánula de alto flujo durante cada sesión y evaluados al inicio y al final mediante el test de pararse y sentarse en un minuto. El diseño fue pre experimental con pre y post test, corte longitudinal, de tipo aplicada. Se obtuvo la media y desviación estándar y se realizó la prueba de rangos con signo de Wilcoxon, se consideró una significancia del 95% y un valor p<0,05 como estadísticamente significativo. Resultados. La media de la edad fue de 58,30 ± 8,17; el 62,6% fue hombres y 37,4% mujeres; los pacientes con condición Post COVID-19 fueron el 71.30%, seguidos de fibrosis pulmonar con 12,17%; con 7,16±1,24 (p<0,000), en el número de repeticiones mediante pararse y sentarse durante un minuto, lo que mejoró principalmente la fatiga muscular (p<0,003). Conclusiones. Se determina como cambio, que se duplica lo mínimamente significativo mediante la prueba de pararse y sentarse durante un minuto. Además, se evidencia mejor respuesta al ejercicio, con menor disnea y fatiga muscular, por efecto de la presión positiva de la cánula de alto flujo.
Chronic respiratory diseases are increasing worldwide, with COPD, pulmonary fibrosis, bronchiectasis and post COVID-19 conditions associated with the respiratory tract standing out. Objective. To determine the effects of respiratory rehabilitation with high-flow nasal cannula in patients with chronic respiratory diseases. Method. Study carried out in a Peruvian military hospital on a sample of 115 patients, who entered a 12-week Respiratory Rehabilitation program with the assistance of the high-flow nasal cannula during each session and evaluated at the beginning and at the end by means of the test of standing up and sitting down in one minute. The design was pre-experimental with pre- and post-test, longitudinal cut, applied type. The mean and standard deviation were obtained and the Wilcoxon signed-rank test was performed, a significance of 95% and a value p<0.05 was considered statistically significant. Results. The mean age was 58.30±8.17; 62.6% were male and 37.4% female; patients with Post COVID-19 condition were 71.30%, followed by pulmonary fibrosis with 12.17%; with 7.16±1.24 (p<0.000), in the number of repetitions by standing and sitting for one minute, which mainly improved muscle fatigue (p<0.003). Conclusions. It is determined as a change, that the minimally significant is duplicated by the test of standing and sitting for one minute. In addition, a better response to exercise is evidenced, with less dyspnea and muscle fatigue, due to the effect of the positive pressure of the high flow cannula.

HumanosRESUMO
Although the level of physical activity in daily life (PADL) plays a vital role concerning the health of subjects with chronic lung diseases, it remains uncertain how PADL patterns compare among different conditions. This study's objective was to compare the PADL levels of subjects with COPD, asthma and idiopathic pulmonary fibrosis (IPF); and to investigate PADL behaviour in different diseases' severity. Stable subjects who had not undergone pulmonary rehabilitation in the previous year were included. Subjects were divided into two subgroups according to disease severity: mild/moderate and severe/very severe. The primary outcome was time spent in moderate-to-vigorous physical activities (MVPA) (Actigraph GT3x) measured during one week over 12 h/day; other assessments included pulmonary function, peripheral muscle strength and exercise capacity. Comparisons among subgroups were corrected for age, BMI and sex. The analysis involved 119 subjects (47 asthma, 48 COPD and 24 IPF). Subjects with asthma had higher PADL levels than those with COPD and IPF (MVPA 18(14-22) vs. 8(4-12) vs. 7(1-12) min/day, respectively; p ancova = 0.002). Subjects with severe/very severe IPF had the lowest PADL level among all subgroups. Adult subjects with asthma have higher PADL levels than those with COPD and IPF, whereas patients with severe and very severe IPF are the most physically inactive subjects.
RESUMO
The tobacco industry promotes electronic nicotine delivery systems (ENDS) and heated tobacco products (HTP) as a safer alternative to conventional cigarettes with misleading marketing sustained by studies with conflict of interest. As a result, these devices sell without regulations and warnings about their adverse effects on health, with a growing user base targeting young people. This systematic review aimed to describe the adverse effects on the respiratory system in consumers of these devices. We conducted a systematic review and bibliometric analysis of 79 studies without conflict of interest evaluating ENDS and HTP effects in the respiratory system in experimental models, retrieved from the PubMed database. We found that the damage produced by using these devices is involved in pathways related to pulmonary diseases, involving mechanisms previously reported in conventional cigarettes as well as new mechanisms particular to these devices, which challenges that the tobacco industry's claims. The present study provides significant evidence to suggest that these devices are an emerging public health problem and that they should be regulated or avoided.

INTRODUCTION: Chronic respiratory diseases (CRD) in children have increased in recent years. Respiratory Rehabilitation is one of the treatments used in this population. OBJECTIVE: To evaluate the impact of a treadmill training program over pediatric patients with CRD in the Josefina Martínez Children's Hospital at Santiago de Chile. METHODS: Retrospective cases series with prospective record of 9 patients 7.1 ± 3.9 years-old with CRD and treadmill training. The patients performed 24 sessions. The Pre-post records of the 6-minute walk test (6MW) and the maximum speed obtained in the Incremental Load Test (ILT) were analyzed. RESULTS: Averages of the distance traveled pre and post-training were 383 ± 142.4 meters and 451.7 ± 142.4 meters respectively (p < 0.0001). The average maximum speed obtained in the ILT was 4.1 ± 1.1 km/h and 5.4 ± 1.27 km/h (p = 0.001). CONCLUSION: The distance walked in the 6-minute walk test and the maximum work capacity improve significantly with treadmill training in these patients with CRD.

Since 1996, the Hospital del Tórax Dr. Antonio A. Centrángolo conducts a pulmonary rehabilitation program that requires patients with chronic pulmonary disease to attend the hospital twice a week. In 2015 the home-based program (HBP) was developed for patients living more than either 10 km or 60 minutes away from the hospital, or with conflicting working schedules. A retrospective study was conducted to describe the adherence to the home-based program by patients with chronic pulmonary disease, and explore adherence-related factors. In 2017, 96 (75.6%) of 127 patients eligible for pulmonary rehabilitation were assigned to the home-based program; they were instructed to complete at least three exercise sessions a week -including aerobic and resistance, segmental strength of upper and lower limbs, and flexibility-; and attend hospital visits every 20 to 30 days; "adherence to the HBP" was determined for patients who attended their final assessment on the fifth visit. A 40.6% (n = 39) of the patients only attended the first visit; 23% (n = 22) adhered to the program. This latter group of patients had shown, at their first assessment, better FVCs (p = 0.013), lower dyspnea scores (p = 0.008), and less than two or more exacerbations during the previous 6 months (p = 0.032). Only one patient needed to take three or more different transportation services to reach the hospital (p = 0.006). The results suggest that adherence to the home-based program was associated to a better clinical status and better access to the hospital.
Desde 1996, el Hospital del Tórax Dr. Antonio A. Cetrángolo aplica un programa de rehabilitación respiratoria, el cual requiere la concurrencia al hospital, dos veces por semana, de los pacientes con enfermedad respiratoria crónica. En 2015, se desarrolló el programa domiciliario (PD) para pacientes que viven a más de 10 km del hospital, o necesitan más de 60 minutos de viaje, o trabajan y tienen incompatibilidad de horarios con el programa hospitalario. Se realizó un estudio retrospectivo con el objetivo de describir la adherencia al programa domiciliario de pacientes con enfermedad respiratoria crónica y explorar los factores relacionados. En 2017, 96 de 127 (75.6%) pacientes elegibles para rehabilitación respiratoria fueron asignados al programa domiciliario y se les indicó cumplimentar al menos tres sesiones semanales de ejercicios de resistencia aeróbica, fuerza segmentaria de miembros superiores e inferiores y flexibilidad; y concurrir al hospital cada 20 o 30 días; a la quinta visita se realizó la reevaluación. Se consideró "adherencia al PD " cuando el paciente completaba la misma. El 40.6% (n = 39) solo asistió a la evaluación inicial y un 23% (n = 22) adhirió al programa. El grupo adherente presentó, al inicio, mejor FVC (p = 0.013), menor score de disnea (p = 0.008), menos de dos o más exacerbaciones en los seis meses previos (p = 0.032). Un solo paciente necesitaba tres o más transportes para llegar al hospital (p = 0.006). Los resultados sugieren que la adherencia al programa domiciliario se relacionó con mejor situación clínica y mejor accesibilidad a la institución.

BACKGROUND: Cognitive impairment has emerged as an important concern in clinical practice in aging population. Several comorbid factors contribute to etiopathogenesis; one disease of interest is chronic respiratory disease. AIM: The aim of this study is to investigate the association of chronic respiratory disease with risk of cognitive impairment in older Mexicans. MATERIALS AND METHODS: Data were obtained from 2782 Mexicans, aged ≥60 years, enrolled in waves I (2001) and III (2012) of the Mexican Health and Aging Study, a prospective cohort of nationally representative sample of older Mexicans. Participants' self-reported responses were used to categorize them into having respiratory disease or not. Study outcome included participants categorized into "cognitively impaired" or "cognitively normal" groups. Multivariable logistic regression models were used to investigate the relationship. RESULTS: Overall, 16% of cohort participants reported cognitively impaired at Wave III. Compared with older Mexicans without chronic respiratory disease diagnosis, those diagnosed were not significantly associated with risk of cognitive impairment [adjusted odds ratio (OR): 0.94, 95% confidence interval (CI): 0.58-1.58]. CONCLUSION: Chronic respiratory disease is not significantly associated with risk of cognitive impairment in older Mexican adults.

Introducción. El Cuestionario de Enfermedad Respiratoria Crónica Autoadminsitrado (CRQ-SAS) es un instrumento utilizado para evaluar calidad de vida relacionada con la salud en diferentes idiomas y poblaciones adultas, aunque no en adolescentes. Este estudio analiza las propiedades psicométricas del CRQ-SAS en una muestra de pacientes adolescentes con enfermedad respiratoria crónica y las relaciona con la clínica ansioso-depresiva. Método. Para analizar propiedades psicométricas del CRQ-SAS, se realizaron análisis factoriales exploratorios y confirmatorios, para estudiar la fiabilidad y validez de la escala. Para evaluar las relaciones con la clínica ansioso-depresiva, se realizaron correlaciones y regresiones lineales múltiples con la Escala de Ansiedad y Depresión Hospitalaria. Se calcularon diferencias de medias en función de variables sociodemográficas. Resultados. El CRQ-SAS fue administrado en 280 niños y adolescentes con enfermedad respiratoria crónica de edades comprendidas entre 9 y 18 años (Media= 12,02) con una distribución similar entre varones y mujeres. Se mantuvo la estructura original de cuatro factores, se eliminaron 3 ítems de la escala original, y se obtuvo una nueva versión de 17 ítems. Esta mostró adecuadas propiedades psicométricas y de validez discriminante. La disnea y la función emocional fueron las dimensiones que mejor predijeron la clínica ansioso-depresiva. Por último, se obtuvieron baremos para la interpretación de las puntuaciones en la calidad de vida relacionada con la salud. Conclusiones. Este cuestionario, utilizado anteriormente en población adulta, puede ser un adecuado instrumento para evaluar calidad de vida relacionada con la salud en pacientes adolescentes con enfermedad respiratoria crónica.
Introduction. The Chronic Respiratory Disease Questionnaire Self-Administered Standardized (CRQ-SAS) format is used to assess health-related quality of life in different languages and adult populations, but it has not been validated in adolescents. This study analyzes the psychometric properties of the CRQ-SAS in a sample of adolescent patients with chronic respiratory disease and correlates them to anxiety and depression. Method. In relation to the CRQ-SAS psychometric properties, exploratory and confirmatory factor analyses were done to assess the instrument's reliability and validity. Correlations and multiple linear regressions with the Hospital Anxiety and Depression Scale were done to assess the relation with anxiety and depression. The mean difference was estimated based on sociodemographic outcome measures. Results. The CRQ-SAS was administered to 280 children and adolescents with chronic respiratory disease aged 9-18 years (mean=12.02), with a similar male-female distribution. The original 4-factor structure was maintained; 3 items were removed from the original scale and a new 17-item version was obtained. This showed adequate psychometric properties and discriminant validity. The dyspnea and emotional functioning domains better predicted anxiety and depression. Lastly, scales were obtained for the interpretation of health-related quality of life scores. Conclusions. This questionnaire, which has been previously used in the adult population, may be an adequate instrument to assess health-related quality of life in adolescent patients with chronic respiratory disease.

PURPOSE: Body composition is known to influence the development and progression of chronic respiratory diseases (CRDs). We sought to characterize the unique anthropometric phenotypes that present with asthma, chronic obstructive pulmonary disease (COPD), and chronic bronchitis across four distinct settings in Peru. METHODS: We collected sociodemographic, clinical history, and spirometry data from 2959 participants from Lima, Tumbes, and rural and urban Puno. We compared the prevalence of CRDs among different study sites and described disease phenotypes. We used single and multivariable linear regression to model the influence of CRD status on various descriptors of body composition. RESULTS: Overall prevalence of CRDs varied across sites with the highest prevalence of asthma in Lima (14.5%) and the highest prevalence of COPD in rural Puno (9.9%). Measures of body composition also varied across sites, with highest mean body mass index (BMI) in Lima (28.4 kg/m2) and the lowest mean BMI in rural Puno (25.2 kg/m2). Participants with COPD had the lowest mean fat mass index (FMI) (10.5 kg/m2) and waist circumference (88.3 cm), whereas participants with asthma had the highest mean FMI (14.5 kg/m2), and waist circumference (94.8 cm). In multivariable analysis, participants with COPD had a lower waist circumference (adjusted mean - 2.97 cm, 95% CI 4.62 to - 1.32 cm) when compared to non-CRD participants. CONCLUSIONS: Our findings provide evidence that asthma and chronic bronchitis are more likely to be associated with obesity and higher fat mass, while COPD is associated with being underweight and having less lean mass.

Mucociliary clearance is a main defense mechanism of the respiratory tract, which can be inherently impaired in primary ciliary dyskinesia (PCD) or reversibly altered in secondary ciliary dyskinesia (SCD). Limited diagnostic test availability likely leads to misdiagnosis or underdiagnosis of PCD in animals. This study evaluated the light and transmission electron microscopy (TEM) changes in the respiratory mucosa of 15 dogs with chronic respiratory disease suspected of PCD. Necropsy was performed in 1 case and 2 dogs were used as negative controls. PCD was confirmed in 1 dog, which presented with chronic otitis, bronchopneumonia, hydrocephalus and ultrastructural abnormalities in 84% of the assessed cilia, including absence of dynein arms and microtubular changes. The 14 other cases showed only nonspecific alterations, such as ciliary disorientation, compound cilia, ciliary edema, and axoneme bubbles in a minority of the evaluated cilia and were classified as SCD. Ciliary ultrastructural analysis can confirm a diagnosis of PCD if specific abnormalities exist. TEM remains an important investigational tool in veterinary medicine, as no other specific test for PCD in dogs has been standardized yet.

Noninvasive ventilation (NIV) has been widely used for the treatment of acute and chronic respiratory diseases (CRD) in both adults and children. In the rehabilitation setting, NIV has shown a positive impact in improving exercise tolerance in patients with chronic obstructive pulmonary disease (COPD). However, there are no data regarding its efficiency in children with CRD. In this article we reviewed the pathophysiological aspects about the origin of the ventilatory constraints during exercise in patients with COPD justifying the inclusion of ventilator assistance in training protocols; also we presented recommendations for proper incorporation of ventilator therapy in rehabilitation. The purpose of this review is to provide data for the design of future studies to evaluate the applicability of this therapeutic strategy for children with chronic respiratory disease.
La asistencia ventilatoria no invasiva (VNI) ha sido ampliamente utilizada para el tratamiento de enfermedades respiratorias agudas y crónicas, tanto en adultos como en población infantil. En el contexto de la rehabilitación, la VNI ha mostrado un impacto positivo al mejorar la tolerancia al ejercicio en pacientes con enfermedad pulmonar obstructiva crónica (EPOC). No obstante, no existen datos respecto a su eficiencia en niños con enfermedades respiratorias crónicas. En el presente texto se revisan los aspectos fisiopatológicos que sustentan el origen de la limitación ventilatoria al ejercicio, presente en los pacientes con EPOC, y que justifican la incorporación de la asistencia ventilatoria a los protocolos de entrenamiento. Por otro lado, se presentan recomendaciones para una apropiada incorporación de la terapia ventilatoria a la rehabilitación. El propósito de la presente revisión es proporcionar datos para el diseño de futuros estudios que evalúen la aplicabilidad de esta estrategia terapéutica a niños con enfermedades respiratorias crónicas.

Introducción: Las infecciones por adenovirus se diseminan rápidamente en recintos cerrados causando brotes asociados a gran morbimortalidad. Objetivos: Identificar tasa de ataque (TA) de infección por adenovirus en hospital de niños con enfermedades respiratorias crónicas (ERC) y evaluar factores asociados que faciliten la infección. Pacientes y Método: Entre junio y octubre de 2010 se evaluaron 50 niños con ERC del Hospital Josefina Martínez. Ellos estuvieron expuestos durante el invierno a pacientes con infección respiratoria aguda baja. A los pacientes con ERC sintomáticos (fiebre y cambio en su signología respiratoria basal) se les realizó Inmunofluorescencia Directa (IFD) Viral. "Caso" fue definido como "paciente sintomático e IFD positiva para Adenovirus". Se evaluaron TA primaria, secundaria y global. Variables como género, edad, traqueostomía y gastrostomía fueron analizadas buscando asociación con los casos. Resultados: El 44 por ciento de los pacientes eran lactantes. El 68 por ciento tenía traqueostomía y 54 por ciento gastrostomía. El primer paciente con Adenovirus ingresó en junio y el caso primario apareció dos semanas después. Hubo 25 casos secundarios que representaron TA secundaria de 51 por ciento. La TA global fue 52 por ciento. No hubo fallecidos. Los lactantes tuvieron un riesgo tres veces mayor que los niños mayores de contraer la infección (OR 3,31 [IC95 por ciento 1,02-10,72; p = 0,046]). No hubo asociación significativa con traqueostomía, gastrostomía ni género. Conclusiones: La alta diseminación de la infección por adenovirus en recintos cerrados obliga a extremar las medidas de prevención de IAAS especialmente en lactantes.
Introduction: Intrahospital adenovirus infections spread rapidly in closed environments causing outbreaks associated with high morbidity and mortality. Objectives: To identify the attack rate (AR) of adenovirus in a hospital treating children with Chronic Respiratory Diseases (CRD) and to evaluate associated factors that facilitate infection. Patients and Methods: Fifty children with CRD were evaluated between June 2010 and October 2010 at Josefina Martinez Hospital. They were exposed to patients with acute lower respiratory infection during winter. Patients with CRD symptoms (fever and change in basal nasal mucus) underwent Viral Direct Immunofluorescence (DIF). The case was defined as "symptomatic patient with positive DIF for Adenovirus". Primary, secondary and global ARs were evaluated. Variables such as gender, age, tracheostomy and gastrostomy were analyzed looking for associations with the cases. Results: 44 percent of patients were infants; 68 percent of children had tracheostomy and 54 percent had gastrostomy. The first patient with Adenovirus was admitted in June and the primary case was reported two weeks later. 25 cases presented secondary AR corresponding to 51percent Global AR was 52 percent overall. No mortality was reported. The risk was three times higher in infants than older children (OR 3.31 [IC95 percent 1.02-10.72; p = 0.046]). No significant associations with tracheostomy, gastrostomy and gender were found. Conclusions: The rapid spread of adenovirus infection in closed environments requires extreme prevention measures especially regarding infants.

Collibacillosis is considered one of the major diseases of the modern poultry industry, due to the significant losses it causes. Escherichia coli contributes not only to the disease itself, by causing weight loss of the birds, but also to the increase in carcasses condemnation during slaughter and processing. Detection of virulence factors in E. coli strains of the APEC pathotype contributes to the characterization and pathogenicity of this agent. PCR techniques have been very helpful in the search for genes that encode those virulence factors. This study aimed to detect the gene Fel A of E. coli by PCR and relate its positivity to low weight in broiler flocks with airsacculitis as diagnosed by the health inspection service. The study involved 40 flocks of broilers slaughtered in a single poultry slaughterhouse, under Federal Sanitary Inspection, located in the state of Rio Grande do Sul, Brazil. Three broilers were randomly selected to obtain one "pool" of three tracheas for each PCR. DNA was extracted using phenol-chloroform and amplified using a pair of primers specific to gene Fel A of E. coli. Of the 40 flocks analyzed by PCR, 35% (14/40) were positive for the gene Fel A. PCR was an effective technique for the detection of gene Fel A in broiler flocks. There was a relationship between the presence of the gene Fel A, weight loss, and increase of the airsacculitis rate...
A colibacilose é considerada uma das principais doenças da indústria avícola moderna, devido aos grandes prejuízos econômicos causados. A Escherichia coli contribui não só para a doença em si, levando à perda de peso das aves, bem como para o aumento da taxa condenação de carcaças durante o abate e processamento. A detecção de fatores de virulência de cepas de E. coli do patotipo APEC colabora para a caracterização de sua patogenicidade e as técnicas de PCR têm sido muito úteis na pesquisa de genes que os codificam. Este estudo objetivou diagnosticar E. coli pela detecção o gene Fel A por PCR e relacionar a positividade para este agente com o baixo peso em frangos de corte provenientes de lotes condenados por aerossaculite. Foram estudados 40 lotes de frangos de corte abatidos em um matadouro avícola sob Inspeção Sanitária Federal, localizado no Estado do Rio Grande do Sul. Foram colhidos aleatoriamente 3 frangos e obtidos "pools" de três traqueias em cada um deles para PCR. O DNA foi extraído pelo método de fenol-clorofórmio e amplificado com pares de "primers" específicos para gene Fel A de E. coli. Dos 40 lotes analisados pela PCR, 35% (14/40) foram positivos para o gene Fel A. A PCR foi eficaz para a detecção do gene Fel A em lotes de frangos de corte e houve relação entre a presença do gene Fel A, a queda de peso e aumento na taxa de aerossaculite...

Synergistic pathological effect of Mycoplasma gallisepticum with other infectious organisms in layer chickens was evaluated in 70 commercial layer chicken farms. Newcastle disease virus and infectious bronchitis virus were confirmed by haemagglutination inhibition test (HI), and Escherichia coli, Pasteurella multocida, Haemophilus paragallinarum andOrnithobacterium rhinotracheale were confirmed by their growth characteristics on agar media and Grams staining. PCR technique was used for the confirmation of Mycoplasma gallisepticum. The mortality rates observed in the occurrence of individual diseases were synergistically increased when they combined with chronic respiratory disease (CRD), which was clearly supported by the gross and histopathological alterations.

Objetivo: existen muchos estudios que reportan los beneficios de la rehabilitación pulmonar, pero son pocos los que presentan el comportamiento y las actividades de estos servicios. Este artículo presenta las características de los servicios, los componentes de manejo y el nivel de entrenamiento de los integrantes del equipo de trabajo, además de las variables o instrumentos utilizados para medir la efectividad e impacto en estos programas. Metodología: estudio descriptivo de corte transversal cuya muestra por conveniencia incluyó siete servicios de rehabilitación pulmonar en cuatro ciudades de Colombia (Bogota, Medellín, Manizales y Cali), seleccionados por la cobertura, por contar con mínimo un año de experiencia, por estar formalmente establecido y por ser reconocido a nivel nacional. El equipo interdisciplinario de cada servicio contestó una encuesta validada a través de una prueba piloto y consenso de expertos. La participación fue voluntaria. Resultados: el inicio laboral de los servicios de rehabilitación pulmonar corresponde en promedio a una década, siendo la EPOC y el asma las patologías de mayor atención. Los programas se caracterizan por su carácter ambulatorio con una duración promedio entre ocho y doce semanas, frecuencia de una hora y tres veces por semana, El director del servicio es regularmente un neumólogo y el coordinador un fisioterapeuta (57,14%); sobresale la formación posgradual de estos profesionales, quienes refieren tener habilidades procedimentales, administrativas y comunicativas, pero califican de regular las habilidades investigativas. El recurso físico y tecnológico es bien evaluado. El 71,42% ha realizado estudios de impacto, pero solo el 28,57% los ha publicado. Todos tienen en común el entrenamiento en miembros superiores, miembros inferiores, musculatura respiratoria, apoyo psicológico, evaluación funcional y calidad de vida. Conclusiones: La efectividad e impacto de los programas es medida con el test de caminata, cuestionarios de calidad de vida y actividades de la vida diaria.
Purpose: there are many studies reporting the benefits of pulmonary rehabilitation, but few of them exhibit the behavior and activities of these services. This article presents the characteristics of services, parts management and training level of team members, in addition to the variables or instruments used to measure the effectiveness and impact in these programs. Method: it was made a cross sectional convenience sample which included seven pulmonary rehabilitation services in four Colombian cities (Bogotá, Medellín, Manizales and Cali), selected by the coverage, for having at least one year of experience and for being formally established and recognized nationwide. The interdisciplinary team of each service answered a survey that was validated through a pilot test and expert consensus. Participation was voluntary. Results: labor onset pulmonary rehabilitation services correspond to an average of a decade, with COPD and asthma pathologies of attention. The programs are characterized by an outpatient treatment with an average duration of eight to twelve weeks, with a frequency of an hour three times a week. Also, the director of the service is regularly a pulmonologist and the coordinator a physiotherapist (57.14%). The posgradual training of these professionals is notable, and they report to have procedural, administrative and communicative skills, but qualify regular there research skills. The physical and technological resources are well tested. 71.42% have done impact studies, but only 28.57% have been published. All have in common training in upper limbs, lower limbs, respiratory muscles, counseling, functional assessment and quality of life. The effectiveness and impact of programs is measured by the walking test, quality of life questionnaires and activities of daily living.

As doenças pulmonares crônicas comprometem as vias aéreas e outras estruturas do pulmão e não podem ser curadas. Afetam milhões de pessoas em todo o mundo, tendo causado mais de quatro milhões de mortes em 2005. Mais de 80% das doenças respiratórias crônicas ocorrem em países de baixa renda. Algumas das mais comuns são a asma (300 milhões), doença pulmonar obstrutiva crônica (80 milhões com formas moderadas a severas), apnéia obstrutiva do sono, doenças pulmonares ocupacionais e hipertensão pulmonar. Os fatores de risco mais importantes para doenças pulmonares crônicas são tabagismo, poluição aérea domiciliar (fumaças de biomassa), poluição ambiental e agentes ocupacionais. Essas doenças são sub-reconhecidas, subdiagnosticadas, subtratadas e insuficientemente prevenidas. Mais ainda, causam prejuízos socioeconômicos tanto para indivíduos como para a sociedade e, provavelmente, se ações urgentes não forem implantadas, aumentarão em 30% seu impacto.
