Previous studies have reported an association between the impairment of cognitive performance and lung diseases. However, whether obstructive or restrictive lung diseases have an impact on cognitive function is still inconclusive. We aimed to investigate the association between cognitive function and obstructive or restrictive lung diseases in Taiwanese adults using the Mini-Mental State Examination (MMSE). In this study, we used data from the Taiwan Biobank. Cognitive function was evaluated using the MMSE. Spirometry measurements of forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) were obtained to assess lung function. Participants were classified into three groups according to lung function, namely, normal, restrictive, and obstructive lung function. In total, 683 patients enrolled, of whom 357 participants had normal lung function (52.3%), 95 had restrictive lung function (13.9%), and 231 had obstructive lung function (33.8%). Compared to the normal lung function group, the obstructive lung function group was associated with a higher percentage of cognitive impairment (MMSE < 24). In multivariable analysis, a low MMSE score was significantly associated with low FVC, low FEV1, and low FEV1/FVC. Furthermore, a low MMSE score was significantly associated with low FEV1 in the participants with FEV1/FVC < 70%, whereas MMSE was not significantly associated with FVC in the participants with FEV1/FVC ≥ 70%. Our results showed that a low MMSE score was associated with low FEV1, low FVC and low FEV1/FVC. Furthermore, a low MMSE score was associated with obstructive lung diseases but not with restrictive lung diseases.

Detection Frequency

Aim. We aimed to estimate the composition and the detection frequency of bacterial species in induced sputum samples from patients with bronchial asthma (BA), chronic obstructive lung disease (COPD) and its combined phenotype (ACOS). Materials and methods. Bacteriological examination of samples of induced sputum in patients with chronic obstructive pulmonary diseases (BA, COPD) was carried out. Results. Patients with asthma-COPD overlap syndrome exhibit more diverse bacterial species composition as represented both by gram-positive Streptococcus sрp., Staphylococcus spр., gram-negative Klebsiella pneumoniaе, Escherichia coli, Serratia marcescens, Pseudomonas aeruginosa, Haemophilus influenzae, Burkholderia cepacia and rodlike bacterium Corynebacterium spр., Actinomyces spр. и Tsukamurella рaurometabola as compared to patients with only one diagnosis of COPD or asthma. In addition, we revealed the differences between microbiological diversity and predominance of Streptococcus spр, Neisseria subflava with decrease of Enterococcus sрр. in samples from patients with complicated forms of obstructive lung diseases as COPD and ACOS, with pulmonary emphysema and/or pneumosclerosis. Conclusion. The biodiversity of lung microbiome could be one of the pathology risk factors in patients with chronic lung diseases, on the other hand reflecting the structural morphological changes in the lung tissue as a result of sustainable inflammation.
