- Integrative assessment of cerebral blood regulation in COPD patients(2024) CORRE, Daniel I.; DE-LIMA-OLIVEIRA, Marcelo; NOGUEIRA, Ricardo C.; CARVALHO-PINTO, Regina M.; BOR-SENG-SHU, Edson; PANERAI, Ronney B.; CARVALHO, Celso R. F.; SALINET, Angela S. M.Cerebrovascular responses were compared between COPD and non-COPD participants. The association between COPD severity and cognitive function was also investigated. Cerebral blood velocity in the middle cerebral artery, blood pressure, and end-tidal CO2 were recorded at rest, followed by a brain activation paradigm, and an inhaled gas mixture (5% CO2) to assess cerebral autoregulation (CA), neurovascular coupling (NVC) and cerebrovascular reactivity to carbon dioxide (CVRCO2), respectively. Pulmonary function, blood gas analysis (COPD) and cognitive function (MoCA test) were also performed. No difference in baseline (systemic and cerebral parameters) and CA was found between 20 severe COPD and 21 non-COPD. Reduced NVC and CVRCO2 test were found in the COPD group. Lower pulmonary function was positively correlated with CA, NVC and CVRCO2 in COPD patients. Cognitive impairment (MoCA<26) was associated with lower NVC responses (COPD and non-COPD) and lower pulmonary function (COPD). Both mechanisms, CVRCO2 and NVC, were lower in COPD patients. Moreover, disease severity and cognitive impaired were associated with worse cerebrovascular regulation.
- Airway epithelium mediates the anti-inflammatory effects of exercise on asthma(2011) VIEIRA, Rodolfo Paula; TOLEDO, Alessandra Choqueta de; FERREIRA, Sergio Cesar; SANTOS, Angela Batista Gomes dos; MEDEIROS, Maria Cristina Rodrigues; HAGE, Marcia; MAUAD, Thais; MARTINS, Milton de Arruda; DOLHNIKOFF, Marisa; CARVALHO, Celso Ricardo Fernandes deAirway epithelium plays an important role in the asthma physiopathology. Aerobic exercise decreases Th2 response in murine models of allergic asthma, but its effects on the structure and activation of airway epithelium in asthma are unknown. BALB/c mice were divided into control, aerobic exercise, ovalbumin-sensitized and ovalbumin-sensitized plus aerobic exercise groups. Ovalbumin sensitization occurred on days 0, 14, 28, 42, and aerosol challenge from day 21 to day 50. Aerobic exercise started on day 22 and ended on day 50. Total cells and eosinophils were reduced in ovalbumin-sensitized group submitted to aerobic exercise. Aerobic exercise also reduced the oxidative and nitrosative stress and the epithelial expression of Th2 cytokines, chemokines, adhesion molecules, growth factors and NF-kB and P2X7 receptor. Additionally, aerobic exercise increased the epithelial expression of IL-10 in non-sensitized and sensitized animals. These findings contribute to the understanding of the beneficial effects of aerobic exercise for chronic allergic airway inflammation, suggesting an immune-regulatory role of exercise on airway epithelium.
- Effects of aerobic exercise on chronic allergic airway inflammation and remodeling in guinea pigs(2012) OLIVO, Clarice R.; VIEIRA, Rodolfo P.; ARANTES-COSTA, Fernanda M.; PERINI, Adenir; MARTINS, Milton Arruda; CARVALHO, Celso Ricardo FernandesWe evaluated the effects of aerobic exercise (AE) on airway inflammation, exhaled nitric oxide levels (ENO), airway remodeling, and the expression of Thl, Th2 and regulatory cytokines in a guinea pig asthma model. Animals were divided into 4 groups: non-trained and non-sensitized (C), non-sensitized and AE (AE), ovalbumin-sensitized and non-trained (OVA), and OVA-sensitized and AE (OVA + AE). OVA inhalation was performed for 8 weeks, and AE was conducted for 6 weeks beginning in the 3rd week of OVA sensitization. Compared to the other groups, the OVA + AE group had a reduced density of eosinophils and lymphocytes, reduced expression of interleukin (IL)-4 and IL-13 and an increase in epithelium thickness (p < 0.05). AE did not modify airway remodeling or ENO in the sensitized groups (p > 0.05). Neither OVA nor AE resulted in differences in the expression of IL-2, IFN-gamma, IL-10 or IL1-ra. Our results show that AE reduces the expression of Th2 cytokines and allergic airway inflammation and induces epithelium remodeling in sensitized guinea pigs.
- Anxiety and depression are related to dyspnea and clinical control but not with thoracoabdominal mechanics in patients with COPD(2015) BORGES-SANTOS, Erickson; WADA, Juliano Takashi; SILVA, Cibele Marques da; SILVA, Ronaldo A.; STELMACH, Rafael; CARVALHO, Celso R.; LUNARDI, Adriana C.Objective: To investigate the relationship between the presence of symptoms of anxiety or depression with breathing pattern and thoracoabdominal mechanics at rest and during exercise in COPD. Methods: Cross-sectional study enrolled 54 patients with COPD ranked according to Hospital Anxiety and Depression Scale (HAD) score and compared to dyspnea, clinical control, hypercapnia, breathing pattern and thoracoabdominal mechanics at rest and during exercise. Results: Seventeen patients with COPD had no symptoms, 12 had anxiety symptoms, 13 had depressive symptoms and 12 had both symptoms. COPD with depressive symptoms presented greater degree of dyspnea (p < 0.01). Poor clinical control was observed in COPD with anxious and/or depressive symptoms (p < 0.05). Breathing pattern and thoracoabdominal mechanics were similar among all groups at rest and during exercise. Conclusions: COPD with symptoms of depression report more dyspnea. Anxiety and depression are associated with poor clinical control without impact on breathing pattern and thoracoabdominal mechanics in COPD.
- Impact of laparoscopic surgery on thoracoabdominal mechanics and inspiratory muscular activity(2013) LUNARDI, Adriana Claudia; PAISANI, Denise de Moraes; TANAKA, Clarice; CARVALHO, Celso Ricardo FernandesObjective: To evaluate the effect of laparoscopic surgery on pulmonary volume distributions and inspiratory muscles activity. Respiratory consequences associated with postoperative pain were also evaluated. Methods: This study enrolled 20 patients without lung disease performed spirometry and chest wall kinematic analyses (i.e., chest wall, upper and lower ribcage and abdominal volumes), and measured the activity of inspiratory muscular before and 2 days after laparoscopic surgery. Pain was also assessed. Results: After laparoscopy, the patients demonstrated decreased volumes in all three thoracoabdominal compartments: abdomen (ABD), upper and lower rib cage (URC and LRC, respectively) compared with the pre-operative measurements: ABD = 0.38 +/- 0.20 L vs. 0.55 +/- 0.25 L; URC = 0.45 +/- 0.18 L vs. 0.55 +/- 0.21 L; and LRC = 0.31 +/- 0.18 L vs. 0.41 +/- 0.23 L; p <0.05. A reduction in the inspiratory muscular activity after surgery was also observed (sternocleidomastoid: 10.6 +/- 5.1 x 10(-3) mV vs. 12.8 +/- 6.3 x 10(-3) my; intercostals: 16.8 +/- 12.4 x 10(-3) mV vs. 25.1 +/- 21.3 x 10(-3) my; p <0.05). In addition, lower volumes during deep breathing were observed in patients who reported significant pain than those who did not (0.51 +/- 0.17 L vs. 0.79 +/- 0.29 L; p <0.05, respectively). Conclusion: Laparoscopic surgery reduces chest wall ventilation and inspiratory muscular activity during deep breathing. The effects appear to depend on the patient's reported pain level.
