Concordant Evidence-Based Interventions in Cardiac and Pulmonary Rehabilitation Guidelines.
Smith, SMS, Chaudhary, K, Blackstock, F
Journal of cardiopulmonary rehabilitation and prevention. 2019;(1):9-18
Abstract
Chronic conditions such as chronic obstructive pulmonary disease (COPD) and cardiovascular disease (CVD) contribute to a significant burden to patients and many experience a reduction in physical functioning, psychological health, and quality of life. The sentinel symptom for COPD and CVD is breathlessness. Rehabilitation programs have been proven to reduce disease symptoms and increase levels of physical and psychological wellness. Pulmonary and cardiac rehabilitation programs have been recommended in international and national guidelines for managing COPD and CVD. Given that these programs seek to reduce breathlessness and improve the physical and psychological functioning of people with COPD and CVD, this review examines the concordant evidence-based interventions in rehabilitation guidelines. The findings of this review indicate that there was concordance in the program design, location of programs, types of health professionals involved in program delivery, assessments of patient at commencement and completion of program, and the delivery of educational topics with minor deviations that were related to disease-specific topics. Apart from disease-specific recommendations, the main divergence from rehabilitation guidelines was found to be dietary screening, inspiratory muscle training, and psychological assessments in evidence-based recommendations for cardiac and pulmonary programs.

The copper-zinc superoxide dismutase activity in selected diseases.
Lewandowski, Ł, Kepinska, M, Milnerowicz, H
European journal of clinical investigation. 2019;(1):e13036
Abstract
Copper-zinc superoxide dismutase (Cu,Zn-SOD) plays a protective role in various types of tissue protecting them from oxidative damage. Alterations in Cu,Zn-SOD (SOD1 and SOD3) activity and its expression have been observed in pathological occurrences most prevalent in modern society, including inflammatory bowel disease, obesity and its implications-diabetes and hypertension, and chronic obstructive pulmonary disease. Moreover, several SOD1 and SOD3 gene polymorphisms have been associated with the risk of developing a particular type of disease, or its exacerbation. This article features recent observations in this topic, aiming to show the importance of proper gene sequence and activity of Cu,Zn-SOD in the aforementioned diseases.

Ginseng: A Qualitative Review of Benefits for Palliative Clinicians.
Davis, MP, Behm, B
The American journal of hospice & palliative care. 2019;(7):630-659
Abstract
Ginseng has been used for centuries to treat various diseases and has been commercially developed and cultivated in the past 300 years. Ginseng products may be fresh, dried (white), or dried and steamed (red). Extracts may be made using water or alcohol. There are over 50 different ginsenosides identified by chromatography. We did an informal systematic qualitative review that centered on fatigue, cancer, dementia, respiratory diseases, and heart failure, and we review 113 studies in 6 tables. There are multiple potential benefits to ginseng in cancer. Ginseng, in certain circumstances, has been shown to improve dementia, chronic obstructive pulmonary disease, and heart failure through randomized trials. Most trials had biases or unknown biases and so most evidence is of low quality. We review the gaps in the evidence and make some recommendations regarding future studies.

Stroke risk among patients with chronic obstructive pulmonary disease: A systematic review and meta-analysis.
Kim, YR, Hwang, IC, Lee, YJ, Ham, EB, Park, DK, Kim, S
Clinics (Sao Paulo, Brazil). 2018;:e177
Abstract
Increased stroke risk among chronic obstructive pulmonary disease patients has not yet been established. In this study, we conducted a systematic review and meta-analysis to assess stroke risk among chronic obstructive pulmonary disease patients. PubMed, EMBASE, and the Cochrane Library were systematically searched from database inception until December 31, 2016 to identify longitudinal observational studies that investigated the association between chronic obstructive pulmonary disease and stroke. Stroke risk was quantified by overall and subgroup analyses, and a pooled hazard ratio was calculated. Study quality was evaluated using the Newcastle-Ottawa Scale. Publication bias was assessed using Begg's rank correlation test. Eight studies met the inclusion criteria. In a random-effects model, significantly increased stroke risk was observed among chronic obstructive pulmonary disease patients (hazard ratio, 1.30; 95% confidence interval, 1.18-1.43). In subgroup analyses stratified by stroke subtype, study quality, and adjustment by socioeconomic status, the association between increased stroke risk and chronic obstructive pulmonary disease patients was robust. Statistically significant publication bias was not detected. In summary, chronic obstructive pulmonary disease was found to be associated with increased stroke risk. Additional prospective studies are required to elucidate the mechanisms underlying the increase in stroke risk and identify effective preventive interventions.

Abstract
PURPOSE OF REVIEW Chronic obstructive pulmonary disease (COPD) is a progressive lung disease with a high prevalence of extrapulmonary manifestations and, frequently, cardiovascular comorbidity. Resveratrol is a food-derived compound with anti-inflammatory, antioxidant, metabolic and cardioprotective potential. Therefore, resveratrol might improve the pulmonary as well as extrapulmonary pathology in COPD. In this review, we will evaluate knowledge on the effects of resveratrol on lung injury, muscle metabolism and cardiovascular risk profile and discuss if resveratrol is a hype or hope for patients with COPD. RECENT FINDINGS Experimental models of COPD consistently show decreased inflammation and oxidative stress in the lungs after resveratrol treatment. These beneficial anti-inflammatory and antioxidant properties of resveratrol can indirectly also improve both skeletal and respiratory muscle impairment in COPD. Recent clinical studies in non-COPD populations show improved mitochondrial oxidative metabolism after resveratrol treatment, which could be beneficial for both lung and muscle impairment in COPD. Moreover, preclinical studies suggest cardioprotective effects of resveratrol but results of clinical studies are inconclusive. SUMMARY Resveratrol might be an interesting therapeutic candidate to counteract lung and muscle impairments characteristic to COPD. However, there is no convincing evidence that resveratrol will significantly decrease the cardiovascular risk in patients with COPD.

Imaging approaches to understand disease complexity: chronic obstructive pulmonary disease as a clinical model.
Sanders, KJC, Ash, SY, Washko, GR, Mottaghy, FM, Schols, AMWJ
Journal of applied physiology (Bethesda, Md. : 1985). 2018;(2):512-520
Abstract
The clinical manifestations of chronic obstructive pulmonary disease (COPD) reflect an aggregate of multiple pulmonary and extrapulmonary processes. It is increasingly clear that full assessment of these processes is essential to characterize disease burden and to tailor therapy. Medical imaging has advanced such that it is now possible to obtain in vivo insight in the presence and severity of lung disease-associated features. In this review, we have assembled data from multiple disciplines of medical imaging research to review the role of imaging in characterization of COPD. Topics include imaging of the lungs, body composition, and extrapulmonary tissue metabolism. The primary focus is on imaging modalities that are widely available in clinical care settings and that potentially contribute to describing COPD heterogeneity and enhance our insight in underlying pathophysiological processes and their structural and functional effects.

Clinical Pharmacology of Oral Maintenance Therapies for Obstructive Lung Diseases.
Pleasants, RA
Respiratory care. 2018;(6):671-689
Abstract
Although inhaled therapies are typically preferred for the maintenance treatment of obstructive lung diseases, oral drug therapies can also play valuable roles. The most commonly used oral agents are phosphodiesterase inhibitors, theophylline, macrolides, leukotriene modifiers, and mucoactive agents. Advantages of these oral agents include the unique pharmacologic mechanisms of action, the avoidance of the challenges of proper inhalational lung administration, and, in most instances, relative drug cost. For many of these agents, anti-inflammatory or immunomodulatory effects are the predominant pharmacologic mechanism that each provides clinical benefit, with the exception of guaifenesin. In addition, theophylline, leukotriene modifiers, chronic macrolides, phosphodiesterase inhibitors, and N-acetylcysteine have been shown to decrease exacerbations in obstructive lung disease. Fairly rapid bronchodilation occurs with the phosphodiesterase inhibitors, theophylline, and leukotriene modifiers, although less than that achieved with inhaled therapies. The clinical roles of phosphodiesterase inhibitors, specifically roflumilast, and macrolides continues to be defined today, whereas the roles theophylline and leukotriene modifiers have probably been largely delineated. Azithromycin is the principal macrolide used chronically for obstructive lung diseases, especially COPD. Although guaifenesin is used widely, its effectiveness is unclear, whereas N-acetylcysteine currently has strong evidence supporting a decreased risk of COPD exacerbations. Mucolytic agents like N-acetylcysteine are used more widely outside the United States in obstructive lung diseases.

Transient Receptor Potential Channels and Chronic Airway Inflammatory Diseases: A Comprehensive Review.
Xia, Y, Xia, L, Lou, L, Jin, R, Shen, H, Li, W
Lung. 2018;(5):505-516
Abstract
Chronic airway inflammatory diseases remain a major problem worldwide, such that there is a need for additional therapeutic targets and novel drugs. Transient receptor potential (TRP) channels are a group of non-selective cation channels expressed throughout the body that are regulated by various stimuli. TRP channels have been identified in numerous cell types in the respiratory tract, including sensory neurons, airway epithelial cells, airway smooth muscle cells, and fibroblasts. Different types of TRP channels induce cough in sensory neurons via the vagus nerve. Permeability and cytokine production are also regulated by TRP channels in airway epithelial cells, and these channels also contribute to the modulation of bronchoconstriction. TRP channels may cooperate with other TRP channels, or act in concert with calcium-dependent potassium channels and calcium-activated chloride channel. Hence, TRP channels could be the potential therapeutic targets for chronic airway inflammatory diseases. In this review, we aim to discuss the expression profiles and physiological functions of TRP channels in the airway, and the roles they play in chronic airway inflammatory diseases.

Physical activity, sedentary behaviour and sleep in COPD guidelines: A systematic review.
Lewthwaite, H, Effing, TW, Olds, T, Williams, MT
Chronic respiratory disease. 2017;(3):231-244
Abstract
OBJECTIVES Physical activity, sedentary and sleep behaviours have strong associations with health. This systematic review aimed to identify how clinical practice guidelines (CPGs) for the management of chronic obstructive pulmonary disease (COPD) report specific recommendations and strategies for these movement behaviours. METHODS A systematic search of databases (Medline, Scopus, CiNAHL, EMbase, Clinical Guideline), reference lists and websites identified current versions of CPGs published since 2005. Specific recommendations and strategies concerning physical activity, sedentary behaviour and sleep were extracted verbatim. The proportions of CPGs providing specific recommendations and strategies were reported. RESULTS From 2370 citations identified, 35 CPGs were eligible for inclusion. Of these, 21 (60%) provided specific recommendations for physical activity, while none provided specific recommendations for sedentary behaviour or sleep. The most commonly suggested strategies to improve movement behaviours were encouragement from a healthcare provider (physical activity n = 20; sedentary behaviour n = 2) and referral for a diagnostic sleep study (sleep n = 4). CONCLUSION Since optimal physical activity, sedentary behaviour and sleep durations and patterns are likely to be associated with mitigating the effects of COPD, as well as with general health and well-being, there is a need for further COPD-specific research, consensus and incorporation of recommendations and strategies into CPGs.

The impact of anaemia and iron deficiency in chronic obstructive pulmonary disease: A clinical overview.
Robalo Nunes, A, Tátá, M
Revista portuguesa de pneumologia. 2017;(3):146-155
Abstract
INTRODUCTION Anaemia is increasingly recognised as an important comorbidity in the context of chronic obstructive pulmonary disease (COPD), but remains undervalued in clinical practice. This review aims to characterise the impact of anaemia and iron deficiency in COPD. METHODS Literature review of studies exploring the relationship between anaemia/iron deficiency and COPD, based on targeted MEDLINE and Google Scholar queries. RESULTS The reported prevalence of anaemia in COPD patients, ranging from 4.9% to 38.0%, has been highly variable, due to different characteristics of study populations and lack of a consensus on the definition of anaemia. Inflammatory processes seem to play an important role in the development of anaemia, but other causes (including nutritional deficiencies) should not be excluded from consideration. Anaemia in COPD has been associated with increased morbidity, mortality, and overall reduced quality of life. The impact of iron deficiency, irrespective of anaemia, is not as well studied, but it might have important implications, since it impacts production of red blood cells and respiratory enzymes. Treatment of anaemia/iron deficiency in COPD remains poorly studied, but it appears reasonable to assume that COPD patients should at least receive the same type of treatment as other patients. CONCLUSIONS Anaemia and iron deficiency continue to be undervalued in most COPD clinical settings, despite affecting up to one-third of patients and having negative impact on prognosis. Special efforts should be made to improve clinical management of anaemia and iron deficiency in COPD patients as a means of achieving better patient care.
