RESUMEN
Chronic obstructive pulmonary disease (COPD) is a disease characterized by chronic airway inflammation and remodeling and lung parenchymal inflammation and destruction, which result in many pulmonary and extrapulmonary manifestations. The anti-inflammatory effect of photobiomodulation (PBM) has been reported in previous studies. This review was conducted to evaluate the direct effect of PBM on lung inflammation in COPD. The other effects of PBM on modulation of peripheral and respiratory muscle metabolism and angiogenesis in lung tissues were also discussed. The databases of PubMed, Cochrane Library, and Google Scholar were searched to find the relevant studies. Keywords included PBM and related terms, COPD-related signs, and lung inflammation. A total of 12 articles were selected and reviewed in this study. Based on the present review, PBM is helpful in reducing lung inflammation through decreasing the inflammatory cytokines and chemokines at multiple levels and increasing anti-inflammatory cytokines. In addition, PBM also improves both peripheral and respiratory muscle metabolism and promote angiogenesis. This review demonstrated that PBM is a promising adjunctive treatment modality for COPD management which merits further validation.

To investigate the effects of photobiomodulation applied to respiratory muscles on lung function, thoracoabdominal mobility, respiratory muscle strength, and functional capacity in COPD patients. This is a randomized double-blind crossover clinical trial. Twelve male COPD patients participated in the study. Participants were randomly allocated to receive two photobiomodulation sessions, 1 week apart: (1) an effective photobiomodulation session applied at the main respiratory muscles by means of a cluster with 69 light-emitting diodes (LEDs), containing 35 red (630 ± 10 nm; 10 mW; 0.2 cm2) and 34 near-infrared (830 ± 20 nm; 10 mW; 0.2 cm2) LEDs and (2) a sham photobiomodulation session, following the same procedures without emitting light. The primary outcomes were pulmonary function (spirometric indexes); thoracoabdominal mobility (cirtometry); respiratory muscle strength (maximal respiratory pressures), assessed at three moments: (1) baseline, (2) 1 h after intervention, and (3) 24 h after intervention; and the functional capacity, assessed by the 6-min walk test (6MWT) at baseline and 24 h after intervention. No significant interactions were found for spirometric variables, maximal respiratory pressures, and cirtometry. However, there was a Time × Condition interaction (F = 18.63; p = 0.001; η2p = 0.62) in the walked distance on the 6MWT, with a significant increase after photobiomodulation intervention (p < 0.01) compared with the baseline. Photobiomodulation applied to respiratory muscles was effective in improving acute functional capacity in COPD patients. To the best of our knowledge, this is the first study assessing the effects of photobiomodulation applied to respiratory muscles in patients with COPD.

Chronic obstructive pulmonary disease (COPD) is characterized by dyspnea, as well as musculoskeletal and systemic manifestations. Photobiomodulation therapy (PBMT) with use of low-level laser therapy (LLLT) and/or light-emitting diode therapy (LEDT) is an electrophysical intervention that has been found to minimize or delay muscle fatigue. The aim of this study was to evaluate the acute effect of PBMT with combined use of lasers diodes, light-emitting diodes (LEDs), magnetic field on muscle performance, exercise tolerance, and metabolic variables during the 6-minute stepper test (6MST) in patients with COPD. Twenty-one patients with COPD (FEV1 46.3% predicted) completed the 6MST protocol over 2 weeks, with one session per week. PBMT/magnetic field or placebo (PL) was performed before each 6MST (17 sites on each lower limb, with a dose of 30 J per site, using a cluster of 12 diodes 4 × 905 nm super-pulsed laser diodes, 4 × 875 nm infrared LEDs, and 4 × 640 nm red LEDs; Multi Radiance Medical™, Solon, OH, USA). Patients were randomized into two groups before the test according to the treatment they would receive. Assessments were performed before the start of each protocol. The primary outcomes were oxygen uptake and number of steps, and the secondary outcome was perceived exertion (dyspnea and fatigue in the lower limbs). PBMT/magnetic field applied before 6MST significantly increased the number of steps during the cardiopulmonary exercise test when compared to the results with placebo (129.8 ± 10.6 vs 116.1 ± 11.5, p = 0.000). PBMT/magnetic field treatment also led to a lower score for the perception of breathlessness (3.0 [1.0-7.0] vs 4.0 [2.0-8.0], p = 0.000) and lower limb fatigue (2.0 [0.0-5.0] vs 4.0 [0.0-7.0], p = 0.001) compared to that with placebo treatment. This study showed that the combined application of PBMT and magnetic field increased the number of steps during the 6MST and decreased the sensation of dyspnea and lower limb fatigue in patients with COPD.

OBJECTIVES: In chronic obstructive pulmonary disease (COPD), quality of life and exercise capacity are altered in relationship to dyspnea. Benefits of inspiratory muscle training (IMT) on quality of life, dyspnea, and exercise capacity were demonstrated, but when it is associated to pulmonary rehabilitation (PR), its efficacy on dyspnea is not demonstrated. The aim of this systematic review with meta-analysis was to verify the effect of IMT using threshold devices in COPD patients on dyspnea, quality of life, exercise capacity, and inspiratory muscles strength, and the added effect on dyspnea of IMT associated with PR (vs. PR alone). STUDY SELECTION: This systematic review and meta-analysis was conducted on the databases from PubMed, Science direct, Cochrane library, Web of science, and Pascal. Following key words were used: inspiratory, respiratory, ventilatory, muscle, and training. The searching period extended to December 2017. Two reviewers independently assessed studies quality. RESULTS: Forty-three studies were included in the systematic review and thirty-seven studies in the meta-analysis. Overall treatment group consisted of six hundred forty two patients. Dyspnea (Baseline Dyspnea Index) is decreased after IMT. Quality of life (Saint George's Respiratory Questionnaire), exercise capacity (6 min walk test) and Maximal inspiratory pressure were increased after IMT. During PR, no added effect of IMT on dyspnea was found. CONCLUSION: IMT using threshold devices improves inspiratory muscle strength, exercise capacity and quality of life, decreases dyspnea. However, there is no added effect of IMT on dyspnea during PR (compared with PR alone).

In this article, we describe the process and strategies that study participants living with chronic obstructive pulmonary disease in central Canada utilized to manage and live well with their illness and its associated symptoms. Drawing on interpretive phenomenology, we interviewed eight participants three times, followed by a member checking focus group and individual interviews. We analyzed interview transcripts using detailed line by line analysis. Our findings suggest participants engaged in a challenging process of recognizing that changes had occurred and then coming to terms with these changes by acknowledging the severity of their condition and the resulting limitations. Then, participants drew upon several strategies to minimize feelings of breathlessness, including taking care of themselves, managing risk, and altering behavior. Participants acknowledged the challenges inherent to this process, yet described how they were able to live well with chronic obstructive pulmonary disease through their adaptations.

OBJECTIVES: : Video-assisted thoracoscopic surgical (VATS) lobectomy is increasingly used for curative intent lung cancer surgery compared to open thoracotomy due to its minimally invasive approach and associated benefits. However, the effects of the VATS approach on postoperative pulmonary complications (PPC), rehabilitation and physiotherapy requirements are unclear; our study aimed to use propensity score matching to investigate this. METHODS: Between January 2012 and January 2016 all consecutive patients undergoing lobectomy via thoracotomy or VATS were prospectively observed. Exclusion criteria included VATS converted to thoracotomy, re-do thoracotomy, sleeve/bilobectomy and tumour size >7 cm diameter (T3/T4). All patients received physiotherapy assessment on postoperative day 1 (POD1), and subsequent treatment as deemed appropriate. PPC frequency was measured daily using the Melbourne Group Scale. Postoperative length of stay (LOS), high dependency unit (HDU) LOS, intensive therapy unit (ITU) admission and in-hospital mortality were observed. Propensity score matching (PSM) was performed using previous PPC risk factors (age, ASA score, body mass index, chronic obstructive pulmonary disease, current smoking) and lung cancer staging. RESULTS: Over 4 years 736 patients underwent lobectomy with 524 remaining after exclusions; 252 (48%) thoracotomy and 272 (52%) VATS cases. PSM produced 215 matched pairs. VATS approach was associated with less PPC (7.4% vs 18.6%; P < 0.001), shorter median LOS (4 days vs 6; P < 0.001), and a shorter median HDU LOS (1 day vs 2; P = 0.002). Patients undergoing VATS required less physiotherapy contacts (3 vs 6; P < 0.001) and reduced therapy time (80 min vs 140; P < 0.001). More patients mobilized on POD1 (84% vs 81%; P = 0.018), and significantly less physiotherapy to treat sputum retention and lung expansion was required ( P < 0.05). CONCLUSIONS: This study demonstrates that patients undergoing VATS lobectomy developed less PPC and had improved associated outcomes compared to thoracotomy. Patients were more mobile earlier, and required half the physiotherapy resources having fewer pulmonary and mobility issues.

A major cause of death in patients undergoing long-term domiciliary oxygen therapy (LTOT) is lung cancer progression. In our institution, we actively perform stereotactic body radiotherapy (SBRT) on patients with early-stage non-small-cell lung cancer undergoing LTOT. In this study, we retrospectively analyzed the treatment efficacy and safety of SBRT for patients with T1-3N0M0 non-small-cell lung cancer who had been prescribed LTOT for treatment of chronic obstructive pulmonary disease (COPD). A total of 24 patients were studied. Their median age was 74 years (range, 63-87 years). The median duration from the start of LTOT to SBRT was 23 months (range, 0-85 months). Four of the 24 patients underwent lobectomy due to lung cancer. The median follow-up duration was 29 months (range, 5-79 months). One patient had a local recurrence. The median survival time was 30 months. The 3-year overall survival was 49%. In 6 of the 24 patients (25%), COPD presented with interstitial pneumonia. The 3-year overall survival for patients with COPD without interstitial pneumonia was significantly better than that for patients with both COPD and interstitial pneumonia (67% and 0%, respectively; P < 0.0001). Grade 5 radiation pneumonitis occurred in one patient (4%) with COPD with interstitial pneumonia. SBRT was tolerated by patients with early-stage non-small-cell lung cancer undergoing LTOT. SBRT should be considered for patients undergoing LTOT. However, clinicians should consider the risk of severe radiation pneumonitis in patients with interstitial pneumonia.

INTRODUCTION: Perfusion (Q) single photon emission computed tomography (SPECT) has been used to divert dose away from higher-functioning lung during radiation therapy (RT) planning. This study aimed to (1) study regional lung function through coregistered pulmonary ventilation/perfusion (V/Q)-SPECT-CT and (2) classify these defects for its potential value in radiation planning in patients with non-small cell lung cancer (NSCLC). METHODS: Patients with stages I to III NSCLC requiring radiation-based therapy were eligible for this prospective study. V/Q-SPECT performed within 2 weeks before the start of radiation was interpreted by nuclear medicine physicians and then measured by a semiquantitative score. The potential mechanism of V and Q defects was analyzed; the potential impact of V/Q-SPECT over Q-SPECT alone was completed through classified applications (high-dose RT versus RT avoidance) during planning. RESULTS: Images of 51 consecutive patients were analyzed. The V and Q defects were matched, reverse mismatched (V defect > Q defect), and mismatched (Q defect > V defect) in 61, 31, and 8% of patients, respectively. Tumor was the leading cause of the defects of ipsilateral lung in 73% of patients. The defect scores of the ipsilateral lung were greater in patients with central primaries than those with peripheral primaries for both V-SPECT (2.3 ± 1.1 versus 1.5 ± 0.8, p = 0.017) and Q-SPECT (2.2 ± 0.8 versus 1.4 ± 0.6, p = 0.000). The patients with chronic obstructive pulmonary disease had greater defect scores in contralateral lung for both V-SPECT (1.5 ± 0.7 versus 1.0 ± 0.8, p = 0.006) and Q-SPECT (1.4 ± 0.6 versus 1.0 ± 0.4, p = 0.010). On assessing the potential value of SPECT on RT plan, 39% of patients could have their RT plan when applying V/Q-SPECT rather than Q-SPECT alone. CONCLUSIONS: V/Q-SPECT provides a more comprehensive functional assessment, may provide additional value over Q-SPECT alone in assessing local pulmonary function, and guide RT plan decisions in patients with NSCLC.

Introdução: DPOC é uma enfermidade respiratória com manifestações sistêmicas que se caracteriza pela presença de obstrução crônica do fluxo aéreo, associada a uma resposta inflamatória. Objetivo: Verificar o efeito da laserterapia de laser 670nm, no tratamento da inflamação pulmonar induzida em ratos. Metodologia: 30 ratos foram divididos em três grupos, dos quais dois foram expostos à fumaça de cigarro durante 45 dias e um deles tratados com laser 670nm. Para análise dos resultados foram realizados LBA e ELISA. Resultados: Os resultados foram submetidos à análise de variância (ANOVA), seguida do teste Newman- Keuls para amostras não pareadas. A análise do LBA demonstrou um aumento altamente significativo no número de neutrófilos no grupo DPOC. O grupo tratado, quando comparado ao grupo DPOC, evidenciou uma diminuição significativa no número de neutrófilos. Para o resultado do ELISA, houve queda altamente significativa de TNF-?, quando tratado com laser 670nm, e significativa de MIP-2 e IL-1?. Conclusão: Verifica-se que a ação do laser de 670nm pode atenuar o processo inflamatório induzido.
Introduction: COPD is a respiratory illness with systemic manifestations, characterized by the presence of chronic airflow obstruction associated with an inflammatory response. Objective: To investigate the effect of laser 670nm laser in the treatment of pulmonary inflammation induced in mice. Methods: 30 rats were divided into three groups, two of which were exposed to cigarette smoke for 45 days and one treated with 670 nm laser. For data analysis and ELISA were performed BAL. Results: Results were subjected to analysis of variance (ANOVA) followed by Newman-Keuls test for unpaired samples. BAL analysis showed a highly significant increase in neutrophils in the COPD group. The treated group compared with the COPD group showed a significant decrease in neutrophils. For the result of the ELISA results were highly significant decrease of TNF-? when treated with 670 nm laser, and the significant MIP-2 and IL-1?. Conclusion: It appears that the action of the 670nm laser can attenuate the inflammatory process induced.

The aim of the study was to evaluate the effects of intravenous laser irradiation of blood (ILIB) on system hemodynamics in patients with chronic obstructive bronchitis (COB) exacerbation. Ninety-seven patients with COB exacerbation were divided into two comparable groups. The 47 patients of the control group received conventional medication, while the 50 patients of the main group received the same therapy plus ILIB, which consisted of 10 everyday 20-min procedures. Central hemodynamic variables were measured prior to and after the treatment. The results demonstrated higher effectiveness of COB treatment when ILIB was applied and that ILIB itself had a positive effect on system circulation in COB exacerbation by changing hyperkinetic hemodynamics into normokinetic one. The study shows that it is appropriate to include ILIB into treatment of COB.

The effect of laser radiation on generation of reactive oxygen species in the whole blood from patients with chronic obstructive pulmonary disease was studied by in vitro recording of luminol-dependent chemiluminescence. Laser irradiation of the blood from patients with increased production of reactive oxygen species decreased the microbicidal potential of cells. In patients with low generation of reactive oxygen species and normal potential of cells, laser exposure increased production of O2 metabolites. Laser radiation had little effect on chemiluminescence of the blood in patients with low generation of reactive oxygen species and decreased functional activity of cells.

159 patients have been observed to assess the efficiency of laseropuncture use in a complex treatment of patients with lung tuberculosis and chronic bronchitis. Disbalance in renal meridian (R), urinary bladder (V) and insufficiency of the energy in colon meridian (60.3%) were observed in patients with tuberculosis associated with chronic bronchitis. Medium deviations of electro-skin conductivity from the physiological gape in meridians of GI, IG, F, V, R in patients with tuberculosis associated with chronic bronchitis considerably differ from those data obtained from patients with only tuberculosis. Obtained data testify more severe disorders of energy balance in meridians of patients having except tuberculosis other associated diseases. Medium parameters of deviations from the physiological gape considerably decrease after the course of laseropuncture compared with those patients treated traditionally. Improve of the course of the chronic bronchitis was noted in patients who underwent laseropuncture.
