Caracterización clínico-espirométrica de pacientes asmáticos con síntomas nocturnos / Clinical-spirometric characterization of asthmatic patients with nocturnal symptoms

Introducción: Los síntomas nocturnos son frecuentes en asmáticos y pueden relacionarse con la gravedad, el grado de control del asma y la función pulmonar. Objetivos: Determinar las características demográficas, clínicas y espirométricas de pacientes asmáticos con síntomas nocturnos, que acuden a consulta externa de neumología. Métodos: Se realizó un estudio descriptivo transversal en 50 pacientes asmáticos con síntomas nocturnos, atendidos por consulta externa en el Hospital Neumológico Benéfico Jurídico, en el período comprendido de mayo de 2017 a mayo de 2018. Resultados: Predominó el sexo femenino (74,0 por ciento), la edad entre 40 y 59 años (52,0 por ciento), los antecedentes familiares de asma o alergia (60,0 por ciento) y múltiples comorbilidades asociadas (78,0 por ciento). La hipersomnia diurna estuvo presente en 80,0 por ciento de los casos, con una frecuencia significativamente elevada en pacientes con asma persistente moderada y severa, disminución de la reversibilidad aguda al broncodilatador, mal control de la enfermedad y limitación de la actividad física. Conclusiones: Los síntomas nocturnos en los pacientes asmáticos son frecuentes y se relacionan con la hipersomnia diurna, la gravedad del asma, el grado de control, la respuesta al broncodilatador y limitación de la actividad física(AU)

Introduction: Nighttime symptoms are frequent in asthmatics and can be related to severity, degree of asthma control and lung function. Objectives: To determine the demographic, clinical and spirometric characteristics of asthmatic patients with nocturnal symptoms, who go to an outpatient pulmonology clinic. Methods: A descriptive cross-sectional study was conducted in 50 asthmatic patients with nocturnal symptoms, they were assisted in the outpatient consultation at the Hospital Neumológico Benéfico Jurídico, from May 2017 to May 2018. Results: Female sex (74.0 percent), age ranging 40 and 59 years (52.0 percent), family history of asthma or allergy (60.0 percent) and multiple associated comorbidities (78.0 percent) predominated. Daytime hypersomnia was present in 80.0 percent of cases, with significantly elevated frequency in patients with moderate and severe persistent asthma, decreased acute reversibility to the bronchodilator, poor disease control, and limited physical activity. Conclusions: Nocturnal symptoms in asthmatic patients are frequent and are related to daytime hypersomnia, asthma severity, degree of control, response to the bronchodilator and limitation of physical activity(AU)

The effect of aircraft noise on sleep disturbance among the residents near a civilian airport: a cross-sectional study

BACKGROUND: Aircraft noise is a major environmental noise problem. This study was conducted in order to investigate the relationship between sleep disturbance and exposure to aircraft noise on the residents who are living near an airport. METHODS: There were 3308 residents (1403 in the high exposure group, 1428 in the low exposure group, and 477 in the non-exposure group) selected as the subjects for this study. The Insomnia severity Index (ISI) and Epworth Sleepiness Scale (ESS) questionnaires were used to evaluate sleep disturbance. RESULTS: The mean ISI and ESS scores were 6.9 ± 6.4 and 5.5 ± 3.7, respectively, and the average scores were significantly greater in the aircraft noise exposure group, as compared to the non-exposure group. The percentage of the abnormal subjects, which were classified according to the results of the ISI and ESS, was also significantly greater in the noise exposure group, as compared to the control group. The odd ratios for insomnia and daytime hypersomnia were approximately 3 times higher in the noise exposure group, as compared to the control group. CONCLUSIONS: The prevalence of insomnia and daytime hypersomnia was higher in the aircraft noise exposure group, as compared to the control group. Further study is deemed necessary in order to clarify the causal relationship.
