Performance on the 6MWT (meters) showed improvement after eight weeks of training, both in the elastic band... (Complete abstract click electronic access below) / Mestre

Background: Chronic obstructive pulmonary disease (COPD) is a devastating illness that affects 4.3% of the population of British Columbia over the age of 45 years. Asthma is known to coexist in 10-20% of individuals with obstructive lung disease, and adds to the substantial burden of illness posed by COPD alone. Inhaled corticosteroids (ICS) are currently recommended for the management of COPD among individuals with frequent exacerbations; however, the ability of inhaled corticosteroids to reduce death and hospitalizations among individuals with COPD is controversial. Less is known about the effectiveness of ICS among individuals who are afflicted with both COPD and asthma. Methods: We used a retrospective cohort study design and administrative data to estimate the relative effectiveness of ICS in reducing hospitalizations or death among individuals with concomitant asthma and COPD, compared with individuals with COPD alone. We used an extended Cox model to estimate this association, with a time-varying measure of exposure to ICS. Results: We did not find any association between ICS and hazard of death or hospitalization among individuals with COPD alone (HR = 0.99; 95% CI: 0.94 – 1.05), however the hazard was 18% lower (HR = 0.82; 95% CI: 0.69-0.99) among individuals with concomitant disease. Conclusions: Individuals with combined COPD and asthma show significant benefit from the use of ICS and are more responsive to the effects of ICS than individuals with COPD alone. / Medicine, Faculty of / Population and Public Health (SPPH), School of / Graduate

Rationale: The prevalence of obesity among individuals with chronic obstructive pulmonary disease (COPD) is increasing, which contributes to further ventilatory limitations, and compromised exercise capacity, and health-related quality of life (HRQOL) compared to COPD alone. Objective: To conduct a systematic review to evaluate the effects of exercise interventions on walking capacity, ventilatory parameters, anthropometrics and HRQOL in individuals with COPD and elevated weight. Methods: A search was conducted on March 16, 2018 of Embase, Medline, CINAHL, AMED and PsycINFO for controlled trials of exercise interventions, involving adults with any stage of severity and stability of COPD with concurrent obesity or overweight. Overall effects were determined with standardized (SMD) and weighted (WMD) mean difference, using Review Manager 5.3. Results: Nineteen studies with 1716 participants (BMI mean ± SD 28.2 ± 5.1 kg/m2) were included. Exercise interventions were effective in improving walking capacity measured by the 6-Minute Walk Test (6MWT), Endurance Shuttle Walk Test and Incremental Shuttle walk Test (12 studies, 1215 participants, SMD 0.25 (95% CI [0.06, 0.43]); p=0.01), fat-free mass index (2 studies, 285 participants, WMD 0.33 kg/m2 (95% CI [0.21, 0.46]); p<0.00001), St. George Respiratory Questionnaire (6 studies, 648 participants, WMD -7.49 points (95% CI [-13.01, -1.98]); p=0.008) and Chronic Respiratory Disease Questionnaire Dyspnea (5 studies, 478 participants, WMD 0.51 points (95% CI [0.00, 1.02]); p=0.05), Emotion (4 studies, 404 participants, WMD 0.28 points, 95% CI [0.03, 0.54]); p=0.03), and Mastery domains (4 studies, 404 participants, WMD 0.31 points (95% CI [0.02, 0.59]); p=0.03). There were no effects on ventilatory parameters or anthropometric measures. Conclusions: Exercise interventions were effective in improving walking capacity and HRQOL in individuals with COPD and elevated weight. There is an important opportunity to establish effective interventions to minimize the functional and health effects in this subset of the COPD population. / Thesis / Master of Health Sciences (MSc)

BACKGROUND Inhalation therapy has proven to be the best way to control the asthma and chronic obstructive pulmonary disease symptoms. The most commonly used delivery system to control these symptoms is the metered-dose inhaler. The primary goal of this study is to demonstrate an association between incorrect inhaler use and patient age. METHODS This is a cross-sectional study, performed at Centro Médico Naval “Cirujano Mayor Santiago Távara”, in Callao, Peru, in 2014. Patients older than 18 years that used metered-dose inhalers were included. We used film recordings of patients using a metered-dose inhaler and compared their technique with the recommendations on the guidelines on the correct use of inhalers of the Spanish Society of Pneumology and Thoracic Surgery (SEPAR). The main variables measured were age and incorrect inhaler use. The results were analyzed with the Chi squared test for bivariate analysis, and for multivariate analysis we used the Poisson regression model with robust variance. RESULTS We included 378 patients in the analysis; 167 were older than 60 years. An association was found between incorrect inhalator technique and age (p=0.014) (PR 1.19 95% CI 1.03 to 1.37). The highest prevalence of incorrect technique was found in the young adult population (88%). There was no association between the incorrect technique and the person who taught it (p=0.114). Finally, this study showed that 81.2% of the study population presented an incorrect inhalation technique. CONCLUSIONS The percentage of incorrect inhaler use, in the general population is high. Even if we found no association between an incorrect technique and the person who taught it; still, there is a high percentage of errors and it was even demonstrated that being instructed by a pulmonologist does not guarantee a correct performance of metered-dose inhaler inhalations. / INTRODUCCIÓN La terapia inhalatoria ha demostrado ser la más rápida y eficaz para el control del asma y la enfermedad pulmonar obstructiva crónica. El inhalador de dosis medida es el más usado por la población. El objetivo de este estudio es evidenciar la asociación entre la técnica inhalatoria incorrecta y la edad. MÉTODOS Estudio observacional, analítico, de corte transversal realizado en Perú durante 2014. Se incluyeron pacientes desde los 18 años que utilizaran inhalador de dosis medida. Se utilizó una lista de verificación de pasos establecidos por la Sociedad Española de Neumología y Cirugía Torácica y filmaciones para evaluar la técnica inhalatoria de los pacientes. Las variables principales fueron la edad y la mala técnica inhalatoria práctica. Para el análisis bivariado se utilizó la prueba Chi cuadrado y para el análisis multivariado regresión de Poisson con varianza robusta. RESULTADOS Se incluyeron 378 pacientes; 167 fueron mayores de 60 años. El estudio reveló que el 81,2% de la población presentó una incorrecta técnica inhalatoria. Se encontró asociación entre la edad y la técnica inhalatoria incorrecta (p=0,014) (PR 1,19 con IC 95% 1,03-1,37). El grupo etario con mayor frecuencia de técnica incorrecta fue el de adultos jóvenes (88%). CONCLUSIONES La frecuencia de uso incorrecto del inhalador en la población es alta y esta característica predomina en el grupo de adultos jóvenes. A pesar de no haber asociación entre la persona que enseña la técnica inhalatoria y el desempeño de la misma, se demostró que existe alta frecuencia de errores, incluso en aquellos pacientes instruidos por un médico especialista.

Title: Analysis of Pharmacotherapy by patients with diagnosis of COPD Student: Marilena Kartali-Kaouni Tutor: Prof. RNDr. Jiri Vlcek, CSc Department of Social and Clinical Pharmacy, Charles University in Prague, Faculty of Pharmacy in Hradec Kralove Background: " Chronic Obstructive Pulmonary Disease (COPD) is characterized by airflow limitation that is not fully reversible. The airflow limitation is usually both progressive and associated with an abnormal inflammatory response of the lungs to noxious particles or gases". Tobacco smoking is the major risk factor in the development of COPD. COPD is a leading cause of morbidity and mortality worldwide. Aim: 1st from the current literature to understand the nature of COPD and obtain information about the aetiopathogenesis of the disease, diagnosis options and summarize the current view of strategies for achieving the goals of treatment. 2nd in a pilot study to analyze drug therapy in COPD patients visiting a pharmacy in Greece. Methods: 56 prescriptions with the diagnosis of COPD were collected during a period of 8 months from a Greek pharmacy. Information from the prescriptions with regard to COPD medications prescribed (active substances, trade names, strength, dosage scheme, pack size), patients characteristics (age and gender) and prescribing...

Background: Respiratory disease has been one of the top three causes of deaths in Macau in the past decade. As one of the chronic respiratory diseases, chronic obstructive pulmonary disease (COPD) is incurable, but is preventable and treatable. COPD patients suffer from recurrent and progressive respiratory symptoms, and this impacts the health and well-being of patients. Self-management education programmes (SMEP) provide teaching and learning guidance for understanding COPD, emotional support and behaviour change needed to carry out disease-specific care in chronic patients. Evidence has demonstrated that SMEP can mediate a change in health-related behaviours, improve symptom control and the quality of life of COPD patients, with an associated reduction in health care utilization. However, SMEP has never been conducted in Macau, and experiences of providing any form of chronic care for COPD patients in this place is lacking. Aims: This study aimed to explore the effects of a specifically designed self-management education programme on Stage II to IV COPD patients in Macau. Design: The study was conducted as an exploratory randomized controlled trial in a mixed methods approach. Both illness perception and self-efficacy beliefs were adopted to formulate the theoretical framework. In the quantitative strand, the assessment of primary outcomes included illness perception, self-efficacy and inhaler technique. The secondary outcomes included pulmonary function, healthcare utilization and health-related quality of life. In the qualitative strand, focus groups were conducted to explore the subjective perception and experiences of self-management of COPD patients. Fifty one eligible COPD patients were recruited and allocated to experimental (26 patients) and control group (25 patients) by block randomization. A SMEP for COPD patients was developed and validated according to Medical Research Council (MRC) framework. Results: Quantitative results indicated that the primary outcomes (illness perception, self-efficacy and inhaler technique) improved in the experimental group after the SMEP. In relating to the secondary outcomes, days of hospitalization were reduced and symptom dimension of disease-specific health related quality of life (St. George Respiratory Questionnaire) improved. Qualitative findings identified the emergence of a core theme ‘Essentiality’ and five sub-themes ‘Helplessness’, ‘Mutual involvement’, ‘Support’, ‘Control’ and ‘Beneficial’, indicating perception and experiences of participants for self-management. These findings indicate a potential relationship of illness perception and self-efficacy in guiding COPD patients to adapt to health-related behaviour. Discussion and Conclusion: This study has obtained evidence for supporting the proposed theoretical framework and expected experimental effect through employing the MRC guidelines. The study also confirms the estimates of recruitment for a definitive RCT, demonstrated readiness and positive impact in Macau COPD patients to receive self-management intervention, and SMEP as an acceptable and preferable mode of chronic care for COPD for the healthcare system of Macau.

Orientador: Irma de Godoy / Resumo: Várias doenças pulmonares são associadas ou apresentam na sua evolução a hipoxemia crônica. A mais comum é a doença pulmonar obstrutiva crônica (DPOC), que é caracterizada pela obstrução ao fluxo aéreo devido a bronquite crônica e/ou enfisema. O tratamento para esta condição é a administração de oxigênio. A oxigenoterapia domiciliar prolongada (ODP) melhora a expectativa de vida, reduz a policitemia, aumenta o peso do corpo, melhora a atividade cardíaca e a função neuropsicológica e aumenta a capacidade para realização de exercícios e atividades da vida diária.

However, we did not identify previous studies evaluating the evolution of these markers in Brazilian patients with COPD. In addition, the association between modifications in disease markers and health-related quality of life (HRQL) are unclear. The objective of this study was to verify the evolution of diagnostic and prognostic markers in COPD patients and the association of these markers with mortality, exacerbation and modifications in HRQL over three years. At baseline were evaluated 133 patients with mild to very severe COPD, 15 patients (11%) died and 23 patients (17%) dropped out during the follow-up period. Therefore, 95 patients (72%) underwent following the evaluations at baseline and after three years: spirometry, body composition, dyspnea perception using the Medical Research Council scale (MRC) and the baseline dyspnea index (BDI), quality of life questionnaire by Saint George's Respiratory Questionnaire (SGRQ), comorbidities (Charlson index), exercise tolerance (six-minute walk distance-6MWD) and the calculate BODE index. After the initial assessment, patients or their relatives were contacted every three months to verify the exacerbations frequency and death. The evolution of the markers was evaluated using the paired t-test. Cox regression analysis was performed to identify mortality predictors. Association of disease markers with exacerbation frequency was assessed by Poisson regression analysis. Logistic regression analysis was used to evaluate the predictors of improvement or worsening of HRQL. After three years of study, there was no change in the values of FEV1 (p=0.23) and BMI (p=0.38).
