Project description:BackgroundA recent national practice guideline recommends the use of opioids for the treatment of refractory dyspnea in patients with advanced chronic obstructive pulmonary disease (COPD). We conducted two qualitative studies to explore the experiences of patients and family caregivers with opioids for refractory COPD-related dyspnea and the perspectives and attitudes of physicians toward opioids in this context.MethodsPatients (n = 8; 5 men, 3 women), their caregivers (n = 12; 5 men, 7 women) and physicians (n = 28, 17 men, 11 women) in Nova Scotia participated in the studies. Semistructured interviews were recorded, transcribed verbatim, coded conceptually and analyzed for emergent themes using interpretive description methodology.ResultsPatients reported that opioids provided a sense of calm and relief from severe dyspnea. Family caregivers felt that opioids helped patients to breathe more "normally," observed improvements in patients' symptoms of anxiety and depression, and experienced reductions in their own stress. Patients reported substantial improvements in their quality of life. All patients and family caregivers wanted opioid therapy to continue. Most physicians were reluctant to prescribe opioids for refractory dyspnea, describing a lack of related knowledge and experience, and fears related to the potential adverse effects and legal censure.InterpretationDiscrepancies between the positive experiences of patients and family caregivers with opioids and the reluctance of physicians to prescribe opioids for refractory dyspnea constitute an important gap in care. Bridging this gap will require initiatives to improve the uptake of practice guidelines and to increase confidence in prescribing opioids for dyspnea refractory to conventional treatment.

Project description:BackgroundThe Modified Medical Research Council (MMRC) scale, baseline dyspnea index (BDI) and the oxygen cost diagram (OCD) are widely used tools for evaluation of limitation of activities due to dyspnea in patients with chronic obstructive pulmonary disease (COPD). There is, however, limited information on how these relate with each other and with multiple parameters of physiological impairment.ObjectivesTo study the interrelationships between MMRC, BDI and OCD scales of dyspnea and their correlation with multiple measures of physiological impairment.Materials and methodsA retrospective analysis of pooled data of 88 male patients with COPD (GOLD stages II, III and IV) was carried out. Dyspnea was evaluated using the MMRC, BDI and OCD scales. Physiological impairment was assessed by spirometry (FVC % predicted and FEV₁ % predicted), arterial blood gas (ABG) analysis and measurement of the 6-min walk distance (6MWD).ResultsThe interrelationships between MMRC, BDI and OCD scales were moderately strong. The BDI and OCD scores had strong correlations with ABG abnormalities, weak correlations with spirometric parameters but none with 6MWD. MMRC grades were significantly associated with BDI and OCD scores but did not show clear associations with spirometric parameters, ABG abnormalities and 6MWD.ConclusionsThe MMRC grades of dyspnea and the BDI and OCD scales are moderately interrelated. While the BDI and OCD scales have significant associations with parameters of physiological impairment, the MMRC scale does not.

Project description:ContextPeople with chronic obstructive pulmonary disease experience dyspnea with activities despite optimal medical management.ObjectivesThe purpose of this study was to test the efficacy of two 12-month dyspnea self-management programs (DSMPs), Internet-based (eDSMP) and face-to-face (fDSMP), compared with a general health education (GHE) control on the primary outcome of dyspnea with activities.MethodsParticipants with chronic obstructive pulmonary disease were randomized to eDSMP (n=43), fDSMP (n=41), or GHE (n=41). The content of the DSMPs were similar and focused on education, skills training, and coaching on dyspnea self-management strategies, including exercise, and only differed in the delivery mode. Dyspnea with activities was measured with the Chronic Respiratory Questionnaire at three, six, and 12 months. Secondary outcomes included exercise behavior and performance, health-related quality of life, self-efficacy for dyspnea management, and perception of support for exercise. The study was registered at Clinicaltrials.gov (NCT00461162).ResultsThere were no differences in dyspnea with activities across groups over 12 months (P=0.48). With the exception of arm endurance (P=0.04), exercise behavior, performance, and health-related quality of life did not differ across groups (P>0.05). Self-efficacy for managing dyspnea improved for the DSMPs compared with GHE (P=0.06). DSMP participants perceived high levels of support for initiating and maintaining an exercise program.ConclusionThe DSMPs did not significantly reduce dyspnea with activities compared with attention control. However, the high participant satisfaction with the DSMPs combined with positive changes in other outcomes, including self-efficacy for managing dyspnea and exercise behavior, highlight the need for additional testing of individually tailored technology-enabled interventions to optimize patient engagement and improve clinically relevant outcomes.

Project description:Background: Dyspnea is the impairing cardinal symptom in COPD, but the underlying brain mechanisms and their relationships to clinical patient characteristics are widely unknown. This study compared neural responses to the perception and anticipation of dyspnea between patients with stable moderate-to-severe COPD and healthy controls. Moreover, associations between COPD-specific brain activation and clinical patient characteristics were examined. Methods: During functional magnetic resonance imaging, dyspnea was induced in patients with stable moderate-to-severe COPD (n = 17) and healthy control subjects (n = 21) by resistive-loaded breathing. Blocks of severe and mild dyspnea were alternating, with each block being preceded by visually cued anticipation phases. Results: During the perception of increased dyspnea, both patients and controls showed comparable brain activation in common dyspnea-relevant sensorimotor and cortico-limbic brain regions. During the anticipation of increased dyspnea, patients showed higher activation in hippocampus and amygdala than controls which was significantly correlated with reduced exercise capacity, reduced health-related quality of life, and higher levels of dyspnea and anxiety. Conclusions: This study suggests that patients with stable moderate-to-severe COPD show higher activation in emotion-related brain areas than healthy controls during the anticipation, but not during the actual perception of experimentally induced dyspnea. These brain activations were related to important clinical characteristics and might contribute to an unfavorable course of the disease via maladaptive psychological and behavioral mechanisms.

Project description:Investigation of whole genome gene expression level changes of the dynamic gene profiling of peripheral blood mononuclear cells (PBMCs) from patients with AECOPD) on day1, 3 and 10, compared to the normal people and stable COPD patients. A five chip study using total RNA recovered from Peripheral Blood Mononuclear Cell of Peripheral Blood.Evaluating the dynamic gene profiling of peripheral blood mononuclear cells (PBMCs) from patients with AECOPD) on day1, 3 and 10 after the hospital admission, to compared with healthy controls or patients with stable COPD. Slides were scanned at 5 μm/pixel resolution using an Axon GenePix 4000B scanner (Molecular Devices Corporation) piloted by GenePix Pro 6.0 software (Axon). Scanned images (TIFF format) were then imported into NimbleScan software (version 2.5) for grid alignment and expression data analysis. Expression data were normalized through quantile normalization and the Robust Multichip Average (RMA) algorithm included in the NimbleScan software. The Probe level (*_norm_RMA.pair) files and Gene level (*_RMA.calls) files were generated after normalization.

Project description:BACKGROUND: The modified version of the Pulmonary Functional Status and Dyspnea Questionnaire (PFSDQ-M) is used in patients with COPD to obtain information about their functional status. It consists of 3 components (change in activities, dyspnea and fatigue) ranging from 0 to 100 and has been shown to be responsive following pulmonary rehabilitation (PR). The interpretation of changes in PFSDQ-M score after an intervention is difficult in the absence of the minimal important difference (MID) of the PFSDQ-M. This study aims at investigating the MID of the PFSDQ-M. METHODS: We enrolled 301 patients with COPD (FEV1 42?±?15%pred) that completed the PFSDQ-M before and after a 3-month PR program (?Chronic Respiratory Disease Questionnaire (CRDQ) +16?±?12 points, ?Six-minute walking distance (6MWD) +47?±?89 m, both p?<?0.001). An anchor-based approach consisted of calculating the correlation between the ?PFSDQ-M and anchors with an established MID (?CRDQ and ?6MWD). Linear regression analyses were performed to predict the MID from these anchors. Secondly several distribution-based approaches (Cohen's effect size, empirical rule effect size and standard error of measurement method) were used. RESULTS: Anchor-based estimates for the different PFSDQ-M-components were between -3 and -5 points based on CRDQ score and -6 (only calculated for change in activities) based on 6MWD. Using the distribution-based methods, the estimates of MID ranged from -3 to -5 points for the different components. CONCLUSIONS: We concluded that the estimate of MID of the PFSDQ-M after pulmonary rehabilitation corresponds to a change of 5 points (range - 3 to -6) in each component in patients with severe COPD.
