Abstract Background: Nasal mucociliary clearance (NMC) responds to autonomic activity through exercise. However, there is a gap in the literature on how NMC responds to resistance exercise. Objective: To evaluate the acute effects of resistance tube exercise on NMC and the autonomic nervous system in smokers. Methods: Clinical trial was performed with 18 individuals. Personal, anthropometric, and smoking history data were collected, and a pulmonary function test was performed by spirometry. The fatigue resistance test was performed in order to obtain the number of repetitions for the prescription of exercise. Heart rate variability was captured using a monitor. Subsequently, the exhaled carbon monoxide (exCO) was measured and a saccharin transit test (STT) was performed for NMC. Results: The non-smoking group presented a significant decrease of 4.0±3.2 minutes in STT after P1 (p=0.021). Regarding HRV, the smoking group presented a significant decrease of mean RR (−90.3±53.0; p=0.011), SDNN (−560.0±1333.2; p=0.008), RMSSD (−13.6±10.5; p=0.011), LFms² (−567.3±836.1; p=0.008), HFms² (−223.8±231.8; p=0.008), SD1 (−9.7±7.4; p=0.011) and SD2 (−20.7±17.0; p=0.008), and an increase of mean HR (10.2±5.9; p=0.011) after P2. In the non-smoking group, a significant decrease was observed in the mean RR (−67.1±70.7; p=0.038), SDNN (−16.8±15.0; p=0.015), RMSSD (−12.3±14.7; p=0.011), LFms² (−831.2±1347.5; p=0.015), SD1 (−8.7±10.4; p=0.011), and SD2 (−22.0±19.1; p=0.015), while an increase in HR (7.1±7.3; p=0.028) was found after P1. Conclusions: The intensity of the resistance exercise applied to the patient was not enough to promote changes in smokers. By contrast, in non-smokers, the same intensity of exercise was effective in promoting alterations in the NMC and autonomic activity. (Int J Cardiovasc Sci. 2021; 34(2):223-230)

Resumo O objetivo deste artigo é avaliar o impacto das emissões da queima da cana-de-açúcar sobre o número de internações hospitalares por doenças respiratórias em uma região canavieira. Registros de internações hospitalares por doenças respiratórias foram adquiridas a partir da base de dados referentes ao sistema de informações hospitalares do sistema único de saúde (SIH-SUS), no período de 28 de março de 2011 a 28 de dezembro de 2012. Níveis de MP10, NO2, O3, temperatura e umidade relativa foram registradas. Modelos de regressão logística foram construídos para analisar a associação entre o número total de internações, poluentes atmosféricos e variáveis meteorológicas. Foram registradas 1.179 internações, dentre elas a pneumonia mostrou aumento significativo no período de queima (p = 0,005). Neste mesmo período observou-se que o cluster MP10 e NO2 influenciou 67,9% (IC95%: 11,111-2,537), seguido do cluster MP10, NO2, O3 e temperatura que influenciou 91,1% (IC95%: 1,116; 3,271) no número total de internações. Durante o período de queima houve maior número de internações por doenças respiratórias, principalmente de pneumonia, quando foi observada a influência dos poluentes e temperatura no processo de adoecimento da população.

Abstract The scope of this article is to evaluate the impact of emissions from sugarcane burning on hospital admission numbers for respiratory diseases in a sugarcane region. Hospital admission records for respiratory diseases were acquired from the database of the Hospital Information System of the Unified Health System (SIH-SUS) in the period from March 28, 2011 to December 28, 2012. Levels of PM10, NO2, O3, Temperature and Relative Humidity were recorded. Logistic regression models were created to analyze the association between the total number of hospitalizations, atmospheric pollutants and meteorological variables. A total of 1,179 hospitalization admissions were recorded, with a significant increase in cases of pneumonia in the burning period (p = 0.005). Likewise, it was observed that the cluster of PM10 and NO2 was influenced 67.9% (95% CI: 11.111-2.537) followed by cluster PM10, NO2, O3 and Temperature that influenced 91.1% (95% CI: 1.116; 3.271) in the total number of hospitalization admissions. During the sugarcane burning period there were more hospitalization admissions due to respiratory tract diseases, mainly pneumonia, where the influence of air pollutants and temperature in the process of illness in the population was detected.
