Abstract:
Introduction: We sought to evaluate the effects of a 12-week pulmonary rehabilitation (PR) program on lung function, mechanics, as well as pulmonary and systemic inflammation in a cohort of 33 individuals with moderate to severe post-COVID-19. Material and Methods: The pulmonary rehabilitation (PR) program employed a combination of aerobic and resistance exercises. Thirty minutes of treadmill training at 75% of the maximum heart rate, combined with 30 min resistance training consisting of 75% of one maximum repetition, three times a week throughout 12 weeks. Results: PR improved the lung function, FVC (p < 0.02), FEV1 (p < 0.02), FEV1/FVC (p < 0.01), MEF25% (p < 0.006), MEF50% (p < 0.03), and MEF75% (p < 0.02). PR also positively influenced lung mechanics, reducing respiratory impedance (Z5Hz, p < 0.03), respiratory reactance (X5Hz, p < 0.01), resistance of the entire respiratory system (R5Hz, p < 0.03), central airway resistance (RCentral, p < 0.03), and peripheral airway resistance (RPeripheral, p < 0.02). Moreover, muscle strength gains were evident, with significant improvements observed in hand grip strength for both the right (p < 0.02) and left (p < 0.01) hands, as well as maximal inspiratory (p < 0.02) and expiratory (p < 0.03) pressures. Additionally, PR exhibited anti-inflammatory effects by reducing the pro-inflammatory cytokines IL-1β (p < 0.0001) and IL-6 (p < 0.0001) and increasing the anti-inflammatory IL-1RA (p < 0.0004) and IL-10 (p < 0.003) and anti-viral IFN-γ (p < 0.0002) and IFN-β (p < 0.008) cytokines in breath condensate and serum samples. Conclusions: Collectively, these findings highlight the effectiveness of PR in ameliorating COVID-19 sequel across respiratory system, skeletal muscle, and immune responses. This highlights its promising potential as a therapeutic intervention for individuals recovering from COVID-19.

COPD: Pathogenesis and Clinical Features
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
