“…Much less biomass fuel is used in developed countries such as Spain. 26 However, the frequency of biomass smoke exposure was high in our study. Available epidemiological studies demonstrate that biomass smoke is an important cause of COPD.…”

“…One survey reported that COPD caused by tobacco plus other inhalants led to greater impairment of quality of life. 26 Our work demonstrated that patients exposed to tobacco plus other risk factors had worse respiratory symptoms and more frequent exacerbations than those who were exposed to tobacco alone. This finding suggests that combined exposure to tobacco plus other risk factors has a noxious additive effect in COPD patients and could result in more serious COPD symptoms.…”

Purpose: Tobacco smoking, biomass smoke, and occupational exposure are the main risk factors for chronic obstructive pulmonary disease (COPD). The present study analyzes data on exposure to these factors in a cohort of patients with COPD and assesses their differences in demographic and clinical characteristics. Patients and Methods: The cross-sectional observational study was conducted from November 2016 to December 2019. Inclusion criteria were patients aged over 40 years old with post-bronchodilator forced expiratory volume in 1 second (FEV 1)/forced vital capacity (FVC) <0.7. At baseline, demographic features and exposure history were recorded. Moreover, respiratory symptoms were assessed by the COPD Assessment Test (CAT) and modified Medical Research Council scale (mMRC). A generalized linear mixed model was used to adjust for potential confounders. Results: A total of 5183 patients with COPD were included in the final analysis. The results demonstrate that exposure to tobacco combined with other risk factors resulted in significantly higher CAT scores (16.0 ± 6.7 vs 15.3 ± 6.3, P = 0.003) and more severe dyspnea (patients with mMRC ≥ 2, 71.5% vs 61.6%, P < 0.001) than exposure to tobacco alone. In addition, COPD patients with biomass smoke exposure alone had higher CAT scores than patients with only tobacco or occupational exposure (17.5 ± 6.3 vs 15.3 ± 6.3, and 15.2 ± 6.3, respectively, P < 0.05 for each comparison) and were more likely to be female and older. In addition, COPD patients who suffered from occupational exposure developed more severe dyspnea than those exposed to tobacco alone (70.8% vs 61.6%, P < 0.05), as did those exposed to biomass smoke alone (74.2% vs 61.6%, P < 0.05). This difference remained strong even after adjustment for potential confounders. Conclusion: There are significant demographic and clinical differences among COPD patients with tobacco smoking, biomass smoke, and occupational exposures.

Background. No previous study has investigated the adherence rate of North-African pulmonologists to the 2017-GOLD PTGs. Aims. To investigate the adherence rate of Tunisian pulmonologists to the 2017-GOLD PTGs and to identify the barriers to their adherence. Methods. This was a cohort study involving clinically stable COPD patients who presented to a pulmonology outpatient consultation. The patients were classified as having been appropriately and inappropriately (over- or undertreatment) treated for the GOLD group. Logistic regression was performed to determine the adherence barriers to the 2017-GOLD PTGs. Results. A total of 296 patients were included (88.1% males, mean age: 68±10 years; GOLD A (7.1%), B (36.1%), C (4.1%), and D (52.7%)). The pulmonologists’ adherence rate to the 2017-GOLD PTGs was 29.7%. There was a significant statistical difference between the adherence rates among the four GOLD groups (A: 19.0%, B: 20.6%, C: 8.3%, and D: 39.1%; p=0.001). Differences were statistically significant between the GOLD group D and groups B (p=0.001) and C (p=0.033). The multivariate analysis showed that age (odds ratio (OR): 0.968), socioeconomic level (high/medium vs. low; OR: 2.950), insurance type (national health insurance vs. others; OR: 2.851), and GOLD groups (A/B vs. C/D; OR: 3.009) significantly influenced the adherence rate to the 2017-GOLD PTGs. Conclusion. The adherence rate of Tunisian pulmonologists to the 2017-GOLD PTGs is low. It seems that the patients’ age, socioeconomic level, national health insurance coverage, and GOLD groups influenced their adherence.

“…[11][12][13] However, it has been suggested that some of these less traditional COPD risk factors, in particular biomass exposure, may interact with smoking to further increase the risk of COPD. Moreover, Lopez-Campos et al 16 showed that subjects with COPD who were exposed to both tobacco and biomass smoke had increased oxygen usage and decreased quality of life.…”
