ABSTRACT

Abstract Background: Right ventricular dysfunction is a major complication in chronic obstructive pulmonary disease (COPD) and, despite its prognostic implications, is rarely considered in routine clinical analysis. Objectives: To compare RV function variables with standard and advanced echocardiographic techniques in patients with stable COPD and controls. Methods: Twenty COPD patients classified as GOLD ≥ II (13 men aged 68.4 ± 8.3 years) and 20 matched controls were compared. Myocardial strain/strain rate indices were obtained by tissue Doppler and two-dimensional speckle tracking echocardiography. Right ventricular ejection fraction was obtained with three-dimensional software. Free wall myocardial thickness (FWMT) and tricuspid annular systolic excursion (TAPSE) were also measured. Numerical variables were compared between groups with Student's t-test or the Mann-Whitney test. Associations between categorical variables were determined with Fisher's exact test. P-values < 0.05 were considered statistically significant. Results: All myocardial deformation indices, particularly global longitudinal strain (-17.2 ± 4.4 vs -21.2: ± 4.4 = 0.001) and 3D right ventricular ejection fraction (40.8 ± 9.3% vs 51.1 ± 6.4% p <0.001) were reduced in COPD patients. These patients presented higher right ventricular FWMT and lower TAPSE values than controls. Conclusion: Myocardial deformation indices, either tissue Doppler or speckle tracking echocardiography and 3D right ventricular ejection fraction, are robust markers of right ventricular dysfunction in patients with stable COPD. Assessing global longitudinal strain by speckle tracking echocardiography is a more practical and reproducible method.

ABSTRACT

Molecular hydrogen exerts biological effects on nearly all organs. It has anti-oxidative, anti-inflammatory, and anti-aging effects and contributes to the regulation of autophagy and cell death. As the primary organ for gas exchange, the lungs are constantly exposed to various harmful environmental irritants. Short- or long-term exposure to these harmful substances often results in lung injury, causing respiratory and lung diseases. Acute and chronic respiratory diseases have high rates of morbidity and mortality and have become a major public health concern worldwide. For example, coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a global pandemic. An increasing number of studies have revealed that hydrogen may protect the lungs from diverse diseases, including acute lung injury, chronic obstructive pulmonary disease, asthma, lung cancer, pulmonary arterial hypertension, and pulmonary fibrosis. In this review, we highlight the multiple functions of hydrogen and the mechanisms underlying its protective effects in various lung diseases, with a focus on its roles in disease pathogenesis and clinical significance.

ABSTRACT

INTRODUCCIÓN: A pesar del progreso de la investigación mundial sobre el comportamiento sedentario, sabemos poco aún acerca de sus relaciones y efectos en la población con enfermedad pulmonar obstructiva crónica (EPOC), por eso el objetivo de esta revisión fue analizar la evidencia actual y más frecuente disponible sobre este tema. MÉTODO: Se utilizaron cinco bases de datos electrónicas para realizar una revisión cualitativa diagnóstica. Los documentos elegibles de los últimos cinco años se analizaron descriptivamente en una tabla de extracción de datos y analizaron por separados los distintos temas encontrados. RESULTADOS: Se evidenció en varios artículos el alto comportamiento sedentario en EPOC, y cómo se relaciona con el nivel de severidad de la enfermedad y con mortalidad. La estrategia principal sugerida fue reemplazar el tiempo sedente con actividad física. Discusión: Los resultados de la revisión son similares a lo estudiado en población de variada comorbilidad. Sin embargo, los precedentes de éstos son más específicos en cuanto a recomendaciones. Deben tomarse en cuenta aquellos hallazgos previos como directriz de estudio en la EPOC, ya que se comparte la base fisiopatológica de inflamación crónica sistémica. CONCLUSIÓN: Algunos hallazgos encontrados con mayor frecuencia, son la relación del comportamiento sedentario con la mortalidad y el desarrollo de mayor comorbilidad en la EPOC, además de la intervención a través de la actividad física, por lo cual es necesario profundizar en esta temática buscando estrategias y recomendaciones específicas para esta población.


INTRODUCTION: Despite the progress of global research on sedentary behavior, we know little about its relationships and its effects on the population with chronic obstructive pulmonary disease (COPD). therefore, the purpose of this review was to analyze the current and most common evidence available on these issues. METHOD: Five electronic databases were used to conduct a qualitative diagnostic review. eligible documents from the past five years were descriptively analyzed in a data extraction table and analyzed separately the various topics found. RESULTS: High sedentary behavior in COPD was evident in several articles, and how it relates to the severity level of the disease and mortality. the main suggested strategy was to replace sedentary time with physical activity. Discussion: The results of this review are similar to what is studied in a population of varied co-morbility. However, their precedents are more specific in terms of recommendations. previous findings should be considered as a study guideline in COPD, as the pathological basis of chronic systemic inflammation is shared. CONCLUSION: Some findings found more frequently are the relationship of sedentary behavior with mortality and the development of greater co-morbility in COPD, in addition to intervention through physical activity, so it is necessary to deepen this topic by looking for strategies and recommendations specific to this population.

ABSTRACT

Chronic obstructive pulmonary disease (COPD), characterized by persistent and not fully reversible airflow restrictions, is currently one of the most widespread chronic lung diseases in the world. The most common symptoms of COPD are cough, expectoration, and exertional dyspnea. Although various strategies have been developed during the last few decades, current medical treatment for COPD only focuses on the relief of symptoms, and the reversal of lung function deterioration and improvement in patient's quality of life are very limited. Consequently, development of novel effective therapeutic strategies for COPD is urgently needed. Stem cells were known to differentiate into a variety of cell types and used to regenerate lung parenchyma and airway structures. Stem cell therapy is a promising therapeutic strategy that has the potential to restore the lung function and improve the quality of life in patients with COPD. This review summarizes the current state of knowledge regarding the clinical research on the treatment of COPD with mesenchymal stem cells (MSCs) and aims to update the understanding of the role of MSCs in COPD treatment, which may be helpful for developing effective therapeutic strategies in clinical settings.

ABSTRACT

OBJECTIVE@#To observe the regulatory effect of electroacupuncture (EA) on small airway function and exercise tolerance in patients with stable chronic obstructive pulmonary disease (COPD).@*METHODS@#A total of 62 patients with stable COPD were randomized into an observation group (31 cases, 1 case dropped off) and a control group (31 cases, 5 cases dropped off). On the base of routine medication and aerobic exercise, the patients of the two groups all received EA at Danzhong (CV 17), Rugen (ST 18), Guanyuan (CV 4), Zhongwan (CV 12), Tianshu (ST 25) and Yingchuang (ST 16). In the observation group, filiform needles were used and inserted perpendicularly, 3 mm in depth. In the control group, the placebo needling method was performed, in which the needle was not inserted through skin at each point. In both groups, electric stimulation with low-frequency electronic pulse instrument was exerted, with continuous wave, 2 Hz in frequency, lasting 30 min each time in the two groups. The treatment was given once every other day, 3 times a week, for 14 treatments totally. Before and after treatment, the following indexes were compared in patients between the two groups, i.e. the lung function indexes (forced expiratory volume in first second [FEV1], forced vital capacity [FVC], the ratio of FEV1 to FVC [FEV1/FVC], maximal voluntary ventilation [MVV], the percentage of maximal expiratory flow [MEF] at 25% of FVC exhaled [MEF25], MEF50 and MEF75 in predicted value), cardiopulmonary exercise test indexs (metabolic equivalent [METS], oxygen uptake per kg body weight [VO@*RESULTS@#After treatment, FVC%, MVV%, MEF75%, MEF50%, VO@*CONCLUSION@#Electroacupuncture can improve the respiratory function and exercise tolerance in COPD patients through removing small airway obstruction and increasing ventilation.

ABSTRACT

RESUMO Objetivo Diversos comprometimentos da deglutição têm sido relatados em indivíduos com doença pulmonar obstrutiva crônica (DPOC), tendo como causa a desvantagem mecânica da musculatura respiratória devido à hiperinsuflação. Dentre as estratégias terapêuticas, até o momento, não foram encontrados relatos na literatura sobre o uso da terapia manual (TM) no manejo dos transtornos da deglutição nesta população. O objetivo do estudo foi verificar os desfechos de um programa de TM sobre a biomecânica da deglutição de indivíduos com DPOC. Método Foram avaliados 18 indivíduos com idade média 66,06±8,86 anos, 61,1% (11) homens e VEF1%médio 40,28±16,73 antes e após-programa de TM. As medidas analisadas foram: tempo de trânsito oral, tempo de trânsito faríngeo (TTF), número de deglutições, resíduos em valéculas (VL) e seios piriformes, penetração/aspiração e excursão hiolaríngea na deglutição das consistências líquida e pastosa. Resultados Houve diferença significativa no TTF (p=0,04), resíduos em VL (p=0,03), elevação máxima do hioide (p=0,003) e deslocamento do hioide (p=0,02) na deglutição da consistência pastosa. Na consistência líquida apenas redução de resíduos em VL (p=0,001). Conclusão O programa de TM interferiu na biomecânica da deglutição de indivíduos DPOC demonstrada pela redução do TTF, resíduos em VL e maior elevação e deslocamento do hioide na consistência pastosa. Na consistência líquida houve redução de resíduos em VL.


ABSTRACT Purpose Several swallowing disorders have been reported in chronic obstructive pulmonary disease (COPD) patients due to the mechanical disadvantage of the respiratory muscles caused by hyperinflation. To date, no reports have been found in the literature among the therapeutic strategies on the use of manual therapy (MT) to manage swallowing disorders in COPD. The aim of the study was to verify the outcomes of a TM program on the biomechanics of swallowing of individuals with COPD. Methods 18 individuals with a mean age of 66.06 ± 8.86 years, 61.1% (11) men, and a FEV1% mean of 40.28 ± 16.73 were evaluated before and after TM. The measures analyzed were: oral transit time, pharyngeal transit time (PTT), number of swallows, vallecular (VL) residue and pyriform sinuses, penetration/aspiration and hyolaryngeal excursion in liquid and pasty consistencies. Results A significant difference was found in PTT (p=0.04), VL residue (p=0.03), maximal hyoid elevation (p=0.003), and displacement of hyoid (p=0.02) in the pasty consistency. In the liquid consistency, we found a decrease in VL residue (p=0.001). Conclusion The MT program influenced the swallowing biomechanics of COPD patients demonstrated by a reduction in PTT and VL residue and increased hyoid elevation and displacement in the pasty consistency. In the liquid consistency, a decrease in VL residue was found.

ABSTRACT

O objetivo deste estudo é descrever os aspectos técnicos e cuidados a serem observados durante a administração de medicamentos inalatórios contidos em inalador pressurizado (pMDI) em pacientes com doença pulmonar obstrutiva crônica em ventilação não-invasiva (VNI). Trata-se de uma revisão integrativa elaborada em quatro fases: (1) busca na literatura; (2) consulta às sociedades médicas; (3) pesquisaem bulas e monografias dos fármacos inalatórios; e (4) contato com empresas de ventiladores, medicamentos e espaçadores. A busca aos estudos foi conduzida a partir de palavras-chaves e restringida a publicações até 31 de dezembro de 2019, nos idiomas português e inglês. Foram selecionados 9 artigos, sendo 1 estudo primário, 6 estudos de revisão e 2 estudos em modelos experimentais de ventilação. Foram incluídas 2 diretrizes a partir da consulta às sociedades médicas e das 8 empresas contatas, quatro fizeram recomendações quanto à técnica inalatória. Não foram encontradas informações sobre a administração dos fármacos em VNI nas bulas e monografias. Recomenda-se atentar para as medidas que podem aumentar a deposição pulmonar dos fármacos inalatórios, como uso de aerocâmara com pMDI, minimização de escape indesejável de ar, sincronia entre paciente-ventilador, disparo do jato na fase inspiratória e inserção de porta de vazamento na máscara ou circuito.

The aim of this study is to describe the technical aspects and cautions to be observed during the administration of inhaled medications contained in a pressurized inhaler (pMDI) in patients with chronic obstructive pulmonary disease on noninvasive ventilation. This integrative review consisted of 4 phases: (1) search in the literature; (2) consultation with medical societies; (3) research on package inserts and monographs of inhaled drugs; and (4) contact with ventilator, medication and spacer companies. The search for studies was based on keywords and restricted to articles published until December 31, 2019, written in Portuguese and English. Nine articles were selected, including 1 primary study, 6 review studies and 2 studies on experimental ventilation models. Two guidelines were included from the consultation with medical societies, and of the 8 companies contacted, 4 made recommendations regarding the inhalation technique. No information was found on the administration of noninvasive ventilation drugs in package inserts and monographs. Attention should be given to measures that increase the pulmonary deposition of inhaled drugs, such as the use of an air chamber with pMDI, minimization of undesirable air leakage, patient-ventilator synchronization, jet firing in the inspiratory phase and insertion of a leak port in the mask or circuit.

ABSTRACT

RESUMO Objetivo Verificar o poder discriminativo e o ponto de corte de diferentes protocolos do teste 4-metre gait speed (4MGS) para identificar capacidade de exercício preservada ou reduzida no teste de caminhada de 6 minutos (TC6min) em pacientes com Doença Pulmonar Obstrutiva Crônica (DPOC); comparar os protocolos do 4MGS; e comparar as características dos indivíduos de acordo com o melhor ponto de corte encontrado. Métodos Foram avaliados 56 pacientes com DPOC. Todos os pacientes foram submetidos à avaliação das características antropométricas, função pulmonar (espirometria) e capacidade funcional de exercício (TC6min e 4 protocolos do 4MGS). No teste 4MGS, os pacientes foram instruídos a caminhar em velocidade usual e máxima em percursos de 4 metros (4MGS 4m - usual e máximo) e 8 metros (4MGS 8m - usual e máximo). Resultados Somente o protocolo 4MGS 4m-máximo foi capaz de identificar capacidade de exercício preservada no TC6min (AUC=0,70) com correlação moderada entre os testes (r=0,52; P<0,0001). O ponto de corte encontrado no 4MGS 4m-máximo foi de 1,27 m/s. Os pacientes com capacidade de exercício preservada (4MGS 4m-máximo ≥1,27m/s) atingiram maior distância percorrida no TC6min em %predito (91±2 vs 76±3; P<0,0001). Nas outras comparações envolvendo gênero, IMC, VEF1%pred e índice GOLD não ocorreram diferenças significantes entre os grupos. Além disso, a concordância de indivíduos classificados com capacidade de exercício preservada e reduzida no TC6min e no 4MGS 4m-máximo foi significante (P=0,008). Conclusão O teste 4MGS 4m-máximo pode ser utilizado para discriminar capacidade de exercício preservada em pacientes com DPOC, e se correlaciona com o TC6min.


ABSTRACT Objective To determine the discriminative capacity and cut-off point of different 4-metre gait speed test (4MGS) protocols in identifying preserved or reduced exercise capacity using the six-minute walk test (6MWT) in patients with Chronic Obstructive Pulmonary Disease (COPD); also, to compare 4MGS protocols and characteristics of individuals according to the best cut-off point. Methods We evaluated fifty-six patients with COPD, all of which were submitted to the assessment of anthropometric characteristics, pulmonary function (spirometry) and functional exercise capacity (6MWT and four protocols of the 4MGS). In the 4MGS test, patients were instructed to walk at normal pace and at maximum speed in a 4 meters course (4MGS 4m - usual pace and at maximum) and 8 meters course (4MGS 8m - usual pace and at maximum). Results Only the 4MGS 4m-maximum protocol was able to identify preserved exercise capacity in the 6MWT (AUC=0.70) with moderate correlation between them (r=0.52; P=0<0.0001). The cut-off point found in the 4MGS 4m-maximum was 1.27 m/s. Patients with preserved exercise capacity (4MGS 4m-maximum ≥1.27m/s) walker greater distances on the 6MWT in %pred (91±2 vs 76±3; P<0.0001). In the other comparisons involving gender, BMI, FEV1% pred and GOLD index there were no significant differences between the groups. In addition, the agreement of individuals classified as preserved and reduced exercise capacity in the 6MWT and 4MGS 4m-maximum was significant (P = 0.008). Conclusion The 4MGS 4m-maximum test can be used to discriminate preserved exercise capacity in patients with COPD and correlates with the 6MWT.

ABSTRACT

RESUMO Objetivo Avaliar a relação entre a adesão à oxigenoterapia domiciliar prolongada (ODP) e a mortalidade em pacientes com doença pulmonar obstrutiva crônica (DPOC) e insuficiência respiratória crônica e suas características clínicas. Métodos Análise retrospectiva longitudinal de 254 pacientes com DPOC e insuficiência respiratória crônica no período de 2008 a 2016. No início do estudo, avaliamos o diagnóstico, valores espirométricos, gasometria arterial, hemograma, oximetria de pulso, composição corporal e questionários de saúde (dispnéia, qualidade). vida, ansiedade e depressão). Para a análise de adesão referida ao ODP, foram incluídos 199 pacientes, divididos de acordo com a prescrição de oxigênio: 12h/dia (G1), 15h/dia (G2) e 24h/dia (G3). As causas e datas da morte foram estudadas durante o período de cinco anos. Resultados Em cinco anos, identificamos 124 óbitos (62,3%). Não houve diferença significativa na mortalidade entre os grupos de adesão (p = 0,75) e não encontramos diferenças nos parâmetros clínicos avaliados. A prescrição de ODP não foi associada à mortalidade (p = 0,07). Na análise de regressão de Cox, não houve associação entre mortalidade e não adesão ao ODP (HR: 0,75; IC95%: 0,21-2,70). O risco de mortalidade aumentou no G3 em comparação ao G1 (HR: 7,16; IC 95%: 1,44-35,38) e naqueles com maior escore de depressão (HR: 1,35; IC: 1,14-1,59). Conclusão Não foi encontrada associação entre adesão à ODP e mortalidade em pacientes com DPOC e insuficiência respiratória. Não houve diferenças clínicas entre os grupos de adesão.


ABSTRACT Objective Assess the relationship between adherence to long-term oxygen therapy (LTOT) with mortality in patients with chronic obstructive pulmonary disease (COPD) and chronic respiratory failure and their clinical features. Methods Longitudinal retrospective analysis of 254 patients with COPD and chronic respiratory failure from 2008 to 2016. At baseline, we evaluated the diagnosis, spirometry values, arterial blood gas analysis, blood count, pulse oximetry, body composition and health questionnaires (dyspnea, quality of life, anxiety and depression). For referred adherence analysis to LTOT we included 199 patients, divided according to prescription of oxygen: 12h/day (G1), 15h/day (G2) and 24h/day (G3). The cause of death and dates were studied over the five-year period. Results In five years we identified 124 deaths (62.3%). No significant difference was found in mortality between the adherence groups (p=0.75) nor did we find differences in the clinical parameters evaluated. LTOT prescription was not associated with mortality (p=0.07). In Cox regression analysis, there was no association between mortality and non-adherence to LTOT (HR: 0.75; IC95%: 0.21-2.70). The risk of mortality was increased in G3 compared with G1 (HR: 7.16; IC 95%: 1.44-35.38) and in those with a higher depression score (HR: 1.35; IC: 1.14-1.59). Conclusion No association was found between LTOT adherence and mortality in patients with COPD and respiratory failure. There were no clinical differences between the adherence groups.

ABSTRACT

ABSTRACT Objective To evaluate the disease and treatment information provided to patients with chronic obstructive pulmonary disease at hospital discharge. Methods This was a cross-sectional study including hospitalized patients with chronic obstructive pulmonary disease at three tertiary hospitals. The study was based on seven items of the Global Initiative for Obstructive Lung Disease (GOLD) discharge guidelines. Two hospitals in this study had a Medical Residency Program in Pulmonology, and one did not have the program. Results Fifty-four patients were evaluated. Large amounts of information were provided concerning effective pharmacological maintenance (item 1), blood gas evaluation/measurement of oxygen saturation (item 2), assessment of inhalation technique (item 4), and maintenance therapy (item 5). Less information was provided regarding comorbidity management planning (item 3), the completion of antibiotic/corticosteroid therapy (item 6) and follow-up with the attending physician or specialist (item 7) had less information. We observed significant differences between hospitals for items 1, 4 and 7, and better performance in hospitals with medical residency in pulmonology. Conclusion Hospitalized patients with chronic obstructive pulmonary disease received little to no information about the seven items addressed by GOLD discharge guidelines. This finding suggests that these guidelines should be used more often by clinicians in hospital with or without medical residency in pulmonology. The lack of specialized care resulted in insufficient amount of information for patients with chronic obstructive pulmonary disease at discharge.


RESUMO Objetivo Avaliar informações sobre a doença e o tratamento fornecidos a pacientes com doença pulmonar obstrutiva crônica no momento da alta hospitalar. Métodos Estudo transversal incluindo pacientes internados com doença pulmonar obstrutiva crônica de três hospitais terciários. O estudo baseou-se em sete itens das diretrizes de alta hospitalar da Global Initiative for Obstructive Lung Disease (GOLD). Dois hospitais participantes deste estudo tinham um Programa de Residência Médica em Pneumologia, e o terceiro não tinha. Resultados Foram avaliados 54 pacientes. Muitas informações foram fornecidas em relação à manutenção farmacológica efetiva (item 1), avaliação de gasometria/medida da saturação de oxigênio (item 2), avaliação da técnica de inalação (item 4) e terapia de manutenção (item 5). Foram fornecidas menos informações em relação ao planejamento do manejo de comorbidade (item 3), a realização de antibioticoterapia/corticoterapia (item 6) e seguimento com o médico assistente ou especialista (item 7). Observaram-se diferenças significativas entre os hospitais para os itens 1, 4 e 7, e melhor desempenho nos hospitais com Programa de Residência Médica em Pneumologia. Conclusão Pacientes hospitalizados com doença pulmonar obstrutiva crônica receberam pouca ou nenhuma informação relacionada aos sete itens abordados pelas diretrizes da GOLD para alta. Esses achados sugerem que essas diretrizes deveriam ser utilizadas com maior frequência por clínicos em hospitais com ou sem Programa Residência Médica em Pneumologia. A falta de atendimento especializado resultou em informação insuficiente para pacientes com doença pulmonar obstrutiva crônica na alta hospitalar.

ABSTRACT

RESUMEN La enfermedad pulmonar obstructiva crónica se caracteriza por una limitación crónica al flujo aéreo poco reversible y asociada en particular al humo de tabaco. Se trata de una enfermedad infradiagnosticada y con una elevada morbimortalidad, lo que implica un problema de salud pública de gran magnitud. Constituye la cuarta causa de muerte en los países del Caribe y se prevé que su prevalencia siga en aumento, lo que representa un elevado costo sanitario. En Cuba la enfermedad pulmonar obstructiva crónica constituye la quinta causa de muerte con una tendencia ascendente en los próximos años, por lo que es un problema de salud, del que no se excluye la provincia de Matanzas, como causa de ingresos frecuentes en sus unidades de atención al grave, las cuales en ocasiones presentan una evolución desfavorable. Entre los factores de riesgo que incrementan esta entidad se encuentran el tabaquismo y la contaminación ambiental, que aumentan la morbilidad por esta entidad con complicaciones que prolongan la estadía hospitalaria y elevan la mortalidad (AU).


SUMMARY Chronic obstructive pulmonary disease is characterized by the chronic limitation of the airflow, almost irreversible and mainly associated to tobacco smoke. It is an underdiagnosed disease with a high morbimortality, meaning a health problem of high magnitude. It is the fourth cause of death in the Caribbean countries and it is expected its prevalence will still increase, representing a high sanitary cost. In Cuba, it is the fifth cause of death with an increasing tendency in the next years, being a health problem because it causes frequent admissions in the Seriously-ill Care Units, frequently having an unfavorable evolution. The province of Matanzas is not excluded from this. Smoking and environmental pollution are among the risk factors favoring this entity, increasing this entity morbidity with complications that make hospital staying longer and mortality higher (AU).

ABSTRACT

Se efectuó un estudio prospectivo observacional, obteniendo datos clínicos y analíticos de pacientes ingresados en la unidad de cuidados intensivos del Hospital Reina Sofía, que precisaron de ventilación mecánica no invasiva. El estudio se llevó a cabo desde el 1 de enero 2013 al 31 de diciembre de 2015. El objetivo principal fue determinar la mortalidad a los 90 días en pacientes ingresados con estas características en dicho periodo. Se definió como fracaso renal agudo al incremento de creatinina sérica > 0.3 mg/dl a las 48 horas con respecto al basal. Los pacientes fueron seguidos durante 90 días. Se analizaron 221 pacientes, 65 (29.4%) presentaron fracaso renal agudo y 156 (70.6%) función renal normal. La mortalidad global a los 90 días fue de 44 (19.9%); en el grupo del fracaso renal agudo fue de 33 (51.6%), y de 11 (7.1%) en los pacientes sin fracaso renal agudo (RR 7.340; IC 95%: 3.974-13.559. p < 0.001). La estancia hospitalaria fue de 24.2 ± 24.1 días en aquellos con fracaso renal agudo vs. 21.5 ± 20.7 días en el segundo grupo; p = 0.429), la estancia en la unidad de cuidados intensivos: 10.9 ± 14.4 con fracaso renal agudo vs. 7.3 ± 9.6; p = 0.357, sin dicha condición, y los días de ventilación mecánica no invasiva: 3.4 ± 3.0 con fracaso renal agudo vs. 2.7 ± 1.9; p = 0.569, en los que no se vieron afectados por la presencia del fracaso renal agudo. Como conclusión, la presencia de fracaso renal agudo es un factor independiente de mortalidad en los pacientes que presentan insuficiencia respiratoria aguda con necesidad de ventilación mecánica no invasiva.


We developed a prospective observational study, obtaining clinical and analytical data of patients admitted to the intensive care unit of the Hospital Reina Sofía, who required noninvasive ventilation, from January 1, 2013 to December 31, 2015. The main objective was to determine the 90-day mortality in these patients and conditions, who required noninvasive ventilation as treatment for acute respiratory failure and who developed acute kidney injury. Acute renal failure was defined as an increase in serum creatinine > 0.3 mg/dl at 48 hours with respect to the baseline. The patients were followed for 90 days. We analyzed 221 patients, 65 (29.4%) presented acute kidney injury and 156 (70.6%) normal renal function. Overall mortality at 90 days was 44 (19.9%). In the group of acute kidneys injury, it was 33 (51.6%), being 11 (7.1%) in patients without acute kidney injury (RR 7.340, 95% CI: 3.974-13.559, p < 0.001). Hospital stay in days was 24.2 ± 24.1 with acute kidney injury vs. 21.5 ± 0.7, p = 0.429; stay in the intensive care unit in days was 10.9 ± 14.4 with acute kidney injury vs. 7.3 ± 9.6, p = 0.357, and days of non-invasive ventilation 3.4 ± 3.0 with acute kidney injury vs. 2.7 ± 1.9, p = 0.569, in those patients not affected by the presence of acute kidney injury. In conclusion, the presence of acute kidney injury is an independent factor of mortality in patients with acute respiratory failure requiring noninvasive ventilation.

ABSTRACT

RESUMO O objetivo deste estudo foi descrever características de sucesso e insucesso do uso da ventilação não invasiva (VNI) na unidade de terapia intensiva (UTI) de um hospital universitário. Trata-se de um estudo observacional prospectivo no qual foram incluídos 75 pacientes, com idade média de 58,3±18,8 anos. Desses, doze necessitaram do uso da VNI por mais de uma vez, totalizando 92 utilizações. Evidenciou-se que, delas, a taxa de sucesso foi de 60,9% (56). O grupo insucesso apresentou mais indivíduos do sexo masculino (p=0,006) e número maior de pacientes com diagnóstico de infecção extrapulmonar (p=0,012). Não foram encontradas diferenças entre os grupos de sucesso e insucesso nos quesitos de modo, modelo, máscara, tempo total de permanência e razões para a instalação da VNI. No grupo insucesso, a pressão positiva inspiratória nas vias aéreas (Ipap) e o volume corrente (VC) foram superiores (p=0,029 e p=0,011, respectivamente). A saturação periférica de oxigênio (p=0,047), o pH (p=0,004), base excess (p=0,006) e o bicarbonato (p=0,013) apresentaram valores inferiores. Concluiu-se que os indivíduos do sexo masculino com diagnóstico de infecção extrapulmonar e que evoluíram com acidose metabólica evoluíram com mais insucesso na utilização da VNI. Esses, necessitaram de parâmetros elevados de Ipap e VC.

No fueron encontradas diferencias entre los grupos con éxito y sin éxito en las cuestiones de modo, modelo, máscara, tiempo total de permanencia y razones para la instalación de la VNI. En el grupo sin éxito, la presión positiva inspiratoria en las vías aéreas (Ipap) y el volumen corriente (VC) fueron superiores (p=0,029 y p=0,011, respectivamente). La saturación periférica de oxígeno (p=0,047), el pH(p=0,004), base excess (p=0,0006) y el bicarbonato (p=0,013) presentaron valores inferiores. De este modo, se concluye que los individuos del sexo masculino con diagnóstico de infecciones extrapulmonares y que progresaron con acidose metabólica avanzaron más sin tener éxito en la utilización de la VNI. Además, necesitaron de parámetros elevados de Ipap y VC.


ABSTRACT The objective of this study was to describe the aspects of success and failure of the use of non-invasive ventilation (NIV) in the intensive care unit (ICU) of a university hospital. This is a prospective observational study that included 75 patients, with 58.3±18.8 years as the mean age. Of these, 12 required the use of NIV more than once, for 92 uses in total. Among these, the success rate was 60.9% (56). The failure group had more males (p=0.006) and a higher number of patients diagnosed with extrapulmonary infection (p=0.012). No differences were found between success and failure groups for the variables mode, model, mask, total length of stay and reasons for NIV installation. In the failure group, inspiratory positive airways pressure (Ipap) and flow volume (FV) were higher (p=0.029 and p=0.011, respectively). Peripheral oxygen saturation (p=0.047), pH (p=0.004), base excess (p=0.006) and bicarbonate (p=0.013) presented lower values. This study concluded that male individuals diagnosed with extrapulmonary infection and whose picture evolved with metabolic acidosis evolved with more failure in NIV use. These patients required higher Ipap and FV parameters.

ABSTRACT

Abstract Background Chronic obstructive pulmonary disease (COPD) has become a major health challenge worldwide due to its increasing incidence and mortality, which have serious repercussions for health-care systems. Methods We conducted a review of international efforts to control COPD in primary care. Results The WHO created the Alma-Ata declaration which established for the first time, access to health care as a human right. This precept led to the implementation of numerous programs including practical approach to Lung Health and variants in several countries; schemes designed to centralize medical care; and resources to improve attention of respiratory diseases by adapting approaches to the health-care needs of local populations. Primary respiratory health care should include actions for timely detection, health education, and targeted treatment, but the challenge for all health systems is to ensure that their programs function adequately, for they still show shortcomings in terms of their application. Conclusions We conclude that offering primary health care based on models that combine opportune diagnoses with suitable treatment can positively influence the course of COPD by treating early stages, thus slowing its progression. However, more extensive education and broader dissemination of information are necessary to achieve this goal.
