[PMID: 38131676 PMCID: PMC10871094 DOI: 10.3390/epidemiologia4040044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2023] [Revised: 10/15/2023] [Accepted: 11/28/2023] [Indexed: 12/23/2023] Open
Abstract
(1) Background: History of TB is a known risk factor for long-term respiratory impairment affecting lung functions in both restrictive and obstructive lung disease. (2) Methods: We analyzed data from the NHANES I Epidemiologic Follow-up Study (NHEFS), a longitudinal study conducted on a noninstitutionalized adult US population aged 25-74 years. Approximately 93 percent of the original NHANES I cohort was successfully traced by the end of the survey period and was available for analysis. The final adjusted model included age groups, gender, family income, lifetime smoking, body mass index (BMI), and frequency of alcohol consumption as potential confounders. (3) Results: The estimated hazards ratio of developing emphysema during follow-up for individuals with a past diagnosis of TB was 54% lower (95% CI = 0.35, 0.61) that that in individuals with no past TB, after controlling for potential confounders and using proportional hazards regression appropriate to the complex sample design. The association, however, was not statistically significant (HR = 0.86, p-value = 0.38) when only a self-reported history of TB was considered as the exposure in an unadjusted model. (4) Conclusions: Tuberculosis (self-reported or LTBI) was strongly (but inversely) associated with emphysema incidence. The association was not statistically significant with only a self-reported history of TB as exposure.

Spielmanns M, Schildge S, Diedrich JP, Valipour A. Therapeutic Success in Swiss COPD Patients Receiving Dual Bronchodilation Therapy as COPD Maintenance Treatment. Clin Pract 2022; 12:46-56. [PMID: 35076494 PMCID: PMC8788262 DOI: 10.3390/clinpract12010006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Revised: 12/15/2021] [Accepted: 01/05/2022] [Indexed: 11/23/2022] Open
Abstract
Health-related quality of life (HRQoL) in patients with moderate to severe chronic obstructive pulmonary disease (COPD) is often reduced by high symptom burden and frequent exacerbations. So far, data on therapeutic success in Swiss COPD patients receiving dual bronchodilation therapy as COPD maintenance treatment are limited. Data from a recently published, non-interventional study on clinical benefit after the start of combined tiotropium-olodaterol treatment were analyzed focusing on Swiss patients compared to the overall cohort including patients from various European countries. Demographic data on the changes in Clinical COPD Questionnaire (CCQ) for the assessment of HRQoL in correlation to symptoms and the number of exacerbations, as well as physician's global assessment (PGE), were evaluated 6 weeks after treatment start. In Switzerland (n = 61), significantly more patients had comorbidities and exacerbations but showed less symptoms compared to the overall cohort (n = 4639). HRQoL improved in both cohorts, with a negative correlation to symptom burden and number of exacerbations in the overall cohort. PGE scores improved after 6 weeks with a better general condition at baseline in Swiss patients (PGE score 4/5: 68.9% [Swiss cohort] vs. 49.0% [overall cohort]. Despite significant differences regarding the presence of symptoms and exacerbations, therapeutic success was similar in both patient groups. Highly symptomatic patients benefited mostly from tiotropium-olodaterol treatment.

Int J Chron Obstruct Pulmon Dis 2021; 16:2533-2544. [PMID: 34522093 PMCID: PMC8433128 DOI: 10.2147/copd.s321197] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2021] [Accepted: 08/23/2021] [Indexed: 11/23/2022] Open
Abstract
Objective This study assessed the characteristics and the relationship between symptoms in any part of the 24-hour (24-h) day, physical activity level (PAL), and other clinical and functional outcomes in stable COPD patients. Patients and Methods Out of the 2162 patients enrolled in the SPACE study (The Symptoms and Physical Activity in COPD patients in Europe, clinicaltrials.gov NCT03031769), 406 (18.8%) were recruited from Romania. Here, we present the Romanian cohort results. Eligible patients were adults with age at least 40 years, confirmed diagnosis of stable COPD, current or former smokers with a smoking history of minimum 10 pack-years. The 24-h respiratory symptoms were assessed using Early Morning Symptoms of COPD Instrument (EMSCI), Evaluating Respiratory Symptoms in COPD (E-RS™: COPD) and Nighttime Symptoms of COPD Instrument (NiSCI). During clinical interview, patients self-evaluated PAL through Exercise as Vital Sign (EVS) and Yale Physical Activity Survey (YPAS). Physicians assessed PAL through their clinical judgment. Results For each combination of 2 between the early morning (EM), daytime (DT) and night-time (NT) symptoms of the 24-h day, there was a significant association (p < 0.001 for each). All symptoms significantly correlated with exacerbation history (p < 0.001 for EM and NT, p=0.002 for DT), and number of severe exacerbations (p < 0.001 for DT, p=0.001 for EM and p=0.026 for NT, respectively). The 24-h symptoms correlated negatively and significantly with PAL (p < 0.001), irrespective of the assessment used. Self-reported PAL negatively correlated with dyspnea, symptom burden, severity of disease and number of exacerbations (p < 0.001). Patients spent an average (standard deviation) of 25.8 (21.0) hours/week performing physical activity. Physicians overestimated their patients' daily PAL. Conclusion A negative and significant correlation between the 24-h day symptoms and PAL was identified in stable COPD patients. Physicians need to routinely assess PAL using adequate tools and start educating inactive COPD patients to optimize their disease outcomes.

Abstract
Physical inactivity is already present among patients with chronic obstructive pulmonary disease (COPD) of mild or moderate airflow obstruction. Most previous studies that reported on determinants of physical activity in COPD included patients with severe COPD. Therefore, the aim of this study was to explore which patient characteristics were related with physical activity in COPD patients with mild or moderate airflow obstruction. Cross-sectional analyses were performed on patients selected from the population-based Netherlands Epidemiology of Obesity study. Patients were included if they had a physician-diagnosed COPD GOLD 0-2 or had newly diagnosed COPD GOLD 1-2. Physical activity was evaluated using the Short Questionnaire to Assess Health-Enhancing Physical Activity (SQUASH) questionnaire and reported in hours per week of metabolic equivalents (MET-h/week). Associations between sociodemographic, lifestyle, clinical and functional characteristics were examined using regression analysis. 323 patients were included in research (77 with physician-diagnosed and 246 with newly diagnosed COPD). We found that physical activity was positively associated with pulmonary function: FEV1 (regression coefficient 0.40 (95% CI 0.09,0.71)) and FVC (regression coefficient 0.34 (95% CI 0.06,0.61)). Physical activity was associated with anxiety (regression coefficient =0.9 (95% CI 0.3,1.6)) only for physician-diagnosed patients. Lung function and anxiety level determine level of physical activity among COPD patients with mild or moderate airflow obstruction. Thus, integrating it into the physical activity plans could help to increase physical activity level of the patients.

Abstract
Primary care physicians (PCPs) play a crucial role in the diagnosis and management of chronic obstructive pulmonary disease (COPD). By working together with patients to target exertional breathlessness and increase physical activity, PCPs have an important role to play, early in the disease course, in improving patient outcomes in both the short and long term. In this article, we consider how physical activity affects disease progression from the PCP perspective. We discuss the role of pharmacological therapy, the importance of an holistic approach and the role of PCPs in assessing and promoting physical activity. The complexity and heterogeneity of COPD make it a challenging disease to treat. Patients' avoidance of activity, and subsequent decline in capacity to perform it, further impacts the management of the disease. Improving patient tolerance of physical activity, increasing participation in daily activities and helping patients to remain active are clear goals of COPD management. These may require an holistic approach to management, including pulmonary rehabilitation and psychological programmes in parallel with bronchodilation therapy, in order to address both physiological and behavioural factors. PCPs have an important role to optimise therapy, set goals and communicate the importance of maintaining physical activity to their patients. In addition, optimal treatment that addresses activity-related breathlessness can help prevent the downward spiral of inactivity and get patients moving again, to improve their overall health and long-term prognosis.

Clinical impact of forced vital capacity on exercise performance in patients with chronic obstructive pulmonary disease. J Thorac Dis 2021; 13:837-846.

Abstract
Background Forced vital capacity (FVC) has been suggested to be a good biomarker for decreased exercise performance in patients with chronic obstructive pulmonary disease (COPD). However, as FVC is highly correlated with forced expiratory volume in 1 second (FEV1), the relationship between FVC and exercise capacity should be assessed within the category of FEV1, i.e., COPD severity. However, this was not considered in previous studies. Thus, limited data are available on the association between reduced FVC and exercise capacity measured by 6-min walk distance (6MWD) based on COPD severity. Methods We performed a cross-sectional study using data from the Korean COPD Subgroup Study (KOCOSS) cohort. We evaluated 1,386 patients with moderate (n=895) and severe-to-very severe (n=491) COPD. Reduced FVC was defined as FVC <80% predicted and short 6MWD as <350 m. Multivariable logistic regression was used to evaluate the association between reduced FVC and short 6MWD. Results There were no significant differences in respiratory symptoms and quality of life between the patients with reduced FVC and those with preserved FVC. However, patients with reduced FVC had shorter 6MWD (30.5 cm in moderate and 34.5 cm in severe-to-very severe COPD) and higher BODE index scores than those with preserved FVC. The cubic spline model revealed 6MWD peaked around 93% predicted of FVC in moderate COPD, whereas FVC showed a positive association with 6MWD in severe-to-very severe COPD. Multivariable analyses showed that reduced FVC was significantly associated with short 6MWD in both moderate [adjusted odds ratio (aOR) =1.44, 95% confidence interval (CI): 1.03-2.02] and severe-to-very severe (adjusted OR =1.55, 95% CI: 1.01-2.40) COPD. Conclusions Reduced FVC was significantly associated with shorter 6MWD in moderate-to-very severe COPD patients, suggesting that reduced FVC might be reflective of 6MWD-measured exercise capacity in moderate-to-very severe COPD.

Effects of Tiotropium/Olodaterol on Activity-Related Breathlessness, Exercise Endurance and Physical Activity in Patients with COPD: Narrative Review with Meta-/Pooled Analyses.

Abstract
Abstract One of the most debilitating symptoms of chronic obstructive pulmonary disease (COPD) is breathlessness, which leads to avoidance of physical activities in daily living and hastens clinical deterioration. Treatment of patients with COPD with inhaled long-acting muscarinic antagonist (LAMA)/long-acting β2-agonist (LABA) combination therapy improves airflow limitation, reduces breathlessness compared with LAMA or LABA monotherapies, and improves health status and quality of life. A large clinical trial programme focusing on the effects of tiotropium/olodaterol combination therapy demonstrated that this LAMA/LABA combination improves lung function and reduces hyperinflation (assessed by serial inspiratory capacity measurements) compared with either tiotropium alone or placebo in patients with COPD. Tiotropium/olodaterol also increases exercise endurance capacity and improves patient perception of the intensity of breathlessness compared with placebo. In this narrative review, we focus on the relationship between improving symptoms during activity, the ability to remain active in daily life and how this may impact quality of life. We consider the benefits of therapy optimisation by means of dual bronchodilation with tiotropium/olodaterol, and present new data from meta-analyses/pooled analyses showing that tiotropium/olodaterol improves inspiratory capacity compared with placebo and tiotropium and improves exercise endurance time compared with placebo after 6 weeks of treatment. We also discuss the importance of taking a holistic approach to improving physical activity, including pulmonary rehabilitation and exercise programmes in parallel with bronchodilator therapy and psychological programmes to support behaviour change.

Abstract
Background Patients with chronic obstructive pulmonary disease (COPD) show signs of reduced physical activity from the early stages of the disease, impacting morbidity and mortality. Data suggest treatment with tiotropium, a long-acting muscarinic antagonist, and olodaterol, a long-acting ß2-agonist (LABA), as monotherapies and in combination, increases exercise capacity. This study assessed the effects of fixed-dose tiotropium/olodaterol (delivered via Respimat®) on physical function in Global Initiative for Chronic Obstructive Lung Disease A-D patients requiring long-acting dual bronchodilation treatment in a real-world setting. Methods This open-label, single arm, noninterventional study measured changes in physical function in COPD patients treated with tiotropium/olodaterol 5/5 μg for approximately 6 weeks (between Visit 1 [baseline] and Visit 2). Primary end point was therapeutic success, defined as a minimum 10-point increase in Physical Functioning Questionnaire (PF-10) score. Secondary end points included change in PF-10 from Visit 1 to Visit 2, the patient's general condition (measured by Physician's Global Evaluation score) at Visit 1 and Visit 2, and patient satisfaction with treatment delivered via the Respimat® device (assessed by Patient Satisfaction Questionnaire) at study end. Results Therapeutic success was observed in 51.5% of 1578 patients (95% confidence interval [CI] 49.0, 54.0) after approximately 6 weeks of treatment with tiotropium/olodaterol. Mean change in PF-10 score between Visit 1 and Visit 2 was 11.6 points (95% CI 10.7, 12.6). Patient general condition improved as indicated by a general improvement in scores between visits. Most patients were very satisfied or satisfied with tiotropium/olodaterol treatment (82.5%), inhalation (87.5%), and handling of Respimat® (85.2%). One percent of patients reported an investigator-defined drug-related adverse events (AE). Conclusion Tiotropium/olodaterol treatment improved physical functioning in COPD patients. An associated increase in patient general condition was observed. Most patients were very satisfied or satisfied with tiotropium/olodaterol treatment, inhaling, and handling of the Respimat® device. No unexpected drug-related AE occurred.

Abstract
BACKGROUND Patients hospitalized with decompensated heart failure are at high risk for readmission within 30 days of discharge. Since physical inactivity is associated with increased health care utilization in other diseases, it may predict rehospitalization in heart failure. METHODS In a single-center, prospective study, physical activity was measured following hospital discharge using an accelerometer on the wrist. We then related this activity to the 30-day all-cause rehospitalization rate in heart failure. Each minute of activity was dichotomized into higher or lower intensity, based on a threshold of 3000 vector magnitude units. Counts above this threshold corresponded to a higher level of physical activity. Logistic regression and Kaplan-Meier survival analyses were used to relate the activity group to 30-day readmissions. RESULTS Ninety-five patients admitted to a heart failure unit were screened; 61 met inclusion criteria and provided consent. Fifty patients were evaluated. Forty-six percent were male, mean age was 71 ± 15 years, and 46% had left ventricular ejection fraction <40%. Thirty-day all-cause hospitalizations occurred in 13 of these 50 patients (26%). Sixty-six percent and 34% were dichotomized into the higher and lower physical activity groups, respectively, over the first week; the latter were more likely to be readmitted within 30 days, with an OR = 5.0 (95% CI, 1.3-19.1), P = .02. CONCLUSION Physical inactivity is related to 30-day all-cause readmissions for heart failure. Further studies are necessary to assess causality and to determine whether treatments directed at increasing physical activity could reduce readmission rate.

Abstract
INTRODUCTION Chronic obstructive pulmonary disease (COPD) is associated with exercise limitation and physical inactivity, which are believed to have significant long-term negative health consequences for patients. While a number of COPD treatments and exercise training programmes increase exercise capacity, there is limited evidence for their effects on physical activity levels, with no clear association between exercise capacity and physical activity in clinical trials. Physical activity depends on a number of behaviour, environmental and physiological factors. We describe the design of the PHYSACTO trial, which is investigating the effects of bronchodilators, either alone or with exercise training, in combination with a standardised behaviour-change self-management programme, on exercise capacity and physical activity in patients with COPD. It is hypothesised that bronchodilators in conjunction with a behaviour-change self-management programme will improve physical activity and that this effect will be amplified by the addition of exercise training. METHODS AND ANALYSIS Patients are being recruited from 34 sites in Australia, New Zealand, the USA, Canada and Europe. Patients receiving a multicomponent intervention designed to support behaviour change related to physical activity are randomised to four treatment arms: placebo, tiotropium, tiotropium+olodaterol, and tiotropium+olodaterol+exercise training. The primary outcome is improvement in exercise capacity after 8 weeks, measured by endurance time during a shuttle walk test. The secondary outcome is improvement in physical activity, including objective accelerometer assessment and patient-reported functioning using the Functional Performance Inventory-Short Form and the novel hybrid PROactive instrument. Additionally, the influence of moderating variables (ie, factors influencing a patient's choice to be physically active) on increases in physical activity is also explored. ETHICS AND DISSEMINATION The study has been approved by the relevant Institutional Review Boards, Independent Ethics Committee and Competent Authority according to national and international regulations. The findings of the trial will be disseminated through relevant peer-reviewed journals and international conference presentations. TRIAL REGISTRATION NUMBER NCT02085161.
