Abstract
BACKGROUND Cough is a common symptom that affects patients' recovery and quality of life after esophagectomy. This study sought to investigate trends in postoperative cough and the factors that influence cough. METHODS A total of 208 of 225 patients were enrolled in this study. The Mandarin Chinese version of the Leicester Cough Questionnaire was administered the day before surgery and at three time points (1 week, 1 month, and 3 months) after esophagectomy to assess patient-reported outcomes. RESULTS All patients' LCQ-MC scores after surgery were lower than presurgery (P < 0.05), with the lowest score found 1 week after esophagectomy. Factors associated with a cough 1 week after surgery included clinical stage of cancer (OR 0.782, 95% CI 0.647-0.944, P = 0.011), anastomotic position (OR 1.241, 95% CI 1.069-1.441, P = 0.005), duration of surgery (OR 0.759, 95% CI 0.577-0.998, P = 0.049), and subcarinal lymph node dissection (OR 0.682, 95% CI 0.563-0.825, P < 0.001). Factors associated with a cough one month after surgery included clinical stage (OR 0.782, 95% CI 0.650-0.940, P = 0.009), anastomotic position (OR 1.293, 95% CI 1.113-1.503, P = 0.001), and maintaining a semi-reclining position (OR 1.440, 95% CI 1.175-1.766, P < 0.001). Factors associated with a cough 3 months after surgery were clinical stage (OR 0.741, 95% CI 0.591-0.928, P = 0.009) and anastomotic position (OR 1.220, 95% CI 1.037-1.435, P = 0.016). CONCLUSIONS This study showed that the factors influencing postoperative cough differed over time following esophagectomy. These results may warrant prospective intervention to better manage patients undergoing surgery for esophageal cancer to prevent postoperative cough.

Abstract
BACKGROUND Chronic cough affects around 10 % of the general adult population, impairing all aspects of quality of life. RESEARCH QUESTION What are the Leicester Cough Questionnaire's psychometric properties? STUDY DESIGN AND METHODS Electronic searches of PubMed, CINAHL, and ScienceDirect databases were conducted from inception until October 1rst 2022. All full-text articles, published in French or English, aimed at evaluating the LCQ's content validity or psychometric properties were included. The COSMIN Risk of Bias checklist was applied to assess their methodological quality and results. Results were qualitatively summarised and rated by a modified GRADE approach. RESULTS 40 studies were included accounting for 8731 adults, subject to cough or a respiratory condition. Chronic cough (>8 weeks) was the most represented. The LCQ's total score is relevant and comprehensible for the assessment of the impact of cough on QoL. The original 3-factor model showed a satisfactory model fit. Good convergent validity was found for the total and physical domain scores. These scores demonstrate good internal consistency and test retest reliability, with some variability noted and they are responsive to change. Recent estimates of MID thresholds were 1.7 and 0.4 for total and domain scores respectively. The quality of the studies is globally poor. INTERPRETATION The LCQ is a valid outcome to assess the intra-individual impact of cough on QoL and to detect large changes in quality of life mainly in a short-term clinical trial setting. CLINICAL TRIAL REGISTRATION The protocol was registered with PROSPERO (CRD42022355191).

Abstract
Chronic obstructive pulmonary disease (COPD) is a chronic, progressive and debilitating disease that affects quality of life (QOL), especially among patients living in poor environments. This study aimed to determine the influencing factors of good QOL among COPD patients living in Zhejiang, China. A cross-sectional study was conducted to collect data from participants in six tertiary hospitals in Zhejiang Province by a simple random sampling method. A validated questionnaire was used to collect general information, environmental factors, and COPD stage. The standardized St. George's Respiratory Questionnaire (SGRQ) was used to assess QOL. Logistic regression was used to determine influencing factors of good QOL among COPD patients at a significance level of α = 0.05. A total of 420 participants were recruited for analysis. The overall prevalence of patients with good QOL was 25.7%. Six variables were found to be associated with good QOL in the multivariable analysis. Patients who were employed had 2.35 times (95% CI 1.03-5.34) greater odds of having good QOL than those who were unemployed. Those whose family income was higher than 100,000 CNY had 2.49 times (95% CI 1.15-5.39) greater odds of having good QOL than those whose family income was lower than 100,000 CNY. Those who had treatment expenses less than 5,000 CNY had 4.57 (95% CI 1.57-13.30) times greater odds of having good QOL than those who had treatment expenses of 5,000 CNY or higher. Those who had mild or moderate airflow limitation were 5.27 times (95% CI 1.61-17.26) more likely to have good QOL than those who were in a severe or very severe stage of COPD. Those who had a duration of illness less than 60 months had 5.57 times (95% CI 1.40-22.12) greater odds of having good QOL than those who had a duration of illness of 120 months or more. Those who were not hospitalized within the past 3 months had 9.39 times (95% CI 1.62-54.43) greater odds of having good QOL than those who were hospitalized more than twice over the past 3 months. Socioeconomic status, disease stage and accessibility were associated with good QOL among COPD patients in Zhejiang Province, China. Increasing family income and implementing measures to improve the accessibility of medical care, including developing a proper system to decrease the cost of treatment for COPD patients, can improve patients' QOL.

Abstract
BACKGROUND Chronic cough is common after lobectomy. Vagus nerves are part of the cough reflex. Accordingly, transection of the pulmonary branches of vagus nerve may prevent chronic cough. And there are no clear recommendations on the management of the pulmonary branches of vagus in any thoracic surgery guidelines. METHODS This is a single-center, randomized controlled trial. Adult patients undergoing elective video-assisted thoracoscopic lobectomy and lymphadenectomy were randomized at a 1:1 ratio to undergo a sham procedure (control group) or transection of the pulmonary branches of the vagus nerve that innervate the bronchial stump plus the caudal-most large pulmonary branch of the vagus nerve. The primary outcome was the rate of chronic cough, as assessed at 3 months after surgery in the intent-to-treat population. RESULTS Between 1 February 2020 and 1 August 2020, 116 patients (59.6±10.1 years of age; 45 men) were randomized (58 in each group). All patients received designated intervention. The rate of chronic cough at 3 months was 19.0% (11/58) in the vagotomy group versus 41.4% (24/58) in the control group (OR=0.332, 95% CI: 0.143-0.767; P =0.009). In the 108 patients with 2-year assessment, the rate of persistent cough was 12.7% (7/55) in the control and 1.9% (1/53) in the vagotomy group ( P =0.032). The two groups did not differ in postoperative complications and key measures of pulmonary function, for example, maximal voluntary ventilation, diffusing capacity of the lungs for carbon monoxide, and forced expiratory volume. CONCLUSION Transecting the pulmonary branches of vagus nerve that innervate the bronchial stump plus the caudal-most large pulmonary branch decreased the rate of chronic cough without affecting pulmonary function in patients undergoing video-assisted lobectomy and lymphadenectomy.

Abstract
INTRODUCTION Cough is a major complication after lung cancer surgery, potentially impacting lung function and quality of life. However, effective treatments for managing long-term persistent postoperative cough remain elusive. In this study, we investigated the potential of a pulmonary rehabilitation training program to effectively address this issue. METHODS Between January 2019 and December 2022, a retrospective review was conducted on patients with non-small cell lung cancer (NSCLC) who underwent lobectomy and lymph node dissection via video-assisted thoracoscopic surgery (VATS) at Daping hospital. Based on their postoperative rehabilitation methods, the patients were categorized into 2 groups: the traditional rehabilitation group and the pulmonary rehabilitation group. All patients underwent assessment using the Leicester cough questionnaire (LCQ) on the third postoperative day. Additionally, at the 6-month follow-up, patients' LCQ scores and lung function were re-evaluated to assess the long-term effects of the pulmonary rehabilitation training programs. RESULTS Among the 276 patients meeting the inclusion criteria, 195 (70.7%) were in the traditional rehabilitation group, while 81 (29.3%) participated in the pulmonary rehabilitation group. The pulmonary rehabilitation group showed a significantly lower incidence of cough on the third postoperative day (16.0% vs 29.7%, P = .018) and higher LCQ scores in the somatic dimension (5.09 ± .81 vs 4.15 ± 1.22, P = .007) as well as in the total score (16.44 ± 2.86 vs 15.11 ± 2.51, P = .018, whereas there were no significant differences in psychiatric and sociological dimensions. At the 6-month follow-up, the pulmonary rehabilitation group continued to have a lower cough incidence (3.7% vs 12.8%, P = .022) and higher LCQ scores across all dimensions: somatic (6.19 ± .11 vs 5.75 ± 1.20, P = .035), mental (6.37 ± 1.19 vs 5.85 ± 1.22, P = .002), sociological (6.76 ± 1.22 vs 5.62 ± 1.08, P < .001), and total (18.22 ± 2.37 vs 16.21 ± 2.53, P < .001). Additionally, lung function parameters including FVC, FVC%, FEV1, FEV1%, MVV, MVV%, DLCO SB, and DLCO% were all significantly higher in the pulmonary rehabilitation group compared to the traditional group. CONCLUSION Pulmonary rehabilitation exercises significantly reduced the incidence of postoperative cough and improved cough-related quality of life in patients undergoing lobectomy, with sustained benefits observed at the 6-month follow-up. Additionally, these exercises demonstrated superior lung function outcomes compared to traditional rehabilitation methods.

Abstract
BACKGROUND To assess the effectiveness and safety of laryngeal mask anesthesia (LMA) in thoracoscopic pulmonary wedge resection based on patient-reported outcomes (PROs). METHODS This randomized controlled trial included 107 patients who underwent thoracoscopic pulmonary wedge resection between June 2017 and December 2021 for pulmonary nodule or pulmonary bullae. In one group, LMA was applied for general anesthesia, and in the other group, endotracheal intubation (ETT) was used. RESULTS A total of 107 patients were included in the study. The symptom assessment based on PROs showed that the incidence of pharyngodynia, trachyphonia, and cough were lower in the LMA group, while the postoperative gastrointestinal reaction did not significantly differ between the two groups. The pain score and global satisfaction score were significantly better in the LMA group. The satisfaction degree of anesthesia and the surgical field did not significantly differ between the two groups. The anesthesia recovery time, indwelling days of chest catheter, and postoperative hospital stay of the LMA group were all shorter, while the operation time, intraoperative blood loss and lowest intraoperative oxygen saturation did not significantly differ between the two groups. The highest intraoperative partial pressure of CO2 was significantly higher in the LMA group. The artery blood gas analysis after the operation did not significantly differ between the two groups. CONCLUSION Compared with ETT, the application of LMA may demonstrate promising advantages in airway management for thoracoscopic pulmonary wedge resection. REGISTRATION NO of clinical trial (ChiCTR2000034905).

Abstract
Background Cough is a common complication after pulmonary surgery. Previous studies lacked a standard measure to assess postoperative cough-related quality of life and recovery. The purpose of this study is to compare postoperative cough regarding changes in health-related quality of life (HRQOL) and recovery trajectory between video-assisted thoracic surgery (VATS) lobectomy and sublobectomy (segmentectomy or wedge resection) for early-stage non-small cell lung cancer (NSCLC) patients via the Leicester Cough Questionnaire in Mandarin Chinese (LCQ-MC). Methods Overall, 156 patients with NSCLC underwent either VATS lobectomy or VATS sublobectomy; LCQ-MC was used to report the impact of postoperative cough on HRQOL for 6 months after surgery. The total scores of LCQ-MC range from 3 to 21, with a higher score indicating better health. Recovery from postoperative cough was defined as LCQ-MC scores returning to preoperative levels. The sensitivity of LCQ-MC to changes in postoperative cough recovery over time was evaluated via its ability to distinguish between surgery types. Results The VATS sublobectomy group reported significantly higher mean LCQ-MC scores at 1 month after surgery, but no significant difference postoperatively at 3 and 6 months after surgery, and returned to preoperative physical (69 vs. 99 days), psychological (67 vs. 99 days), social (50 vs. 98 days) and total (69 vs. 99 days) scores faster than the VATS lobectomy group (all p < 0.05). Conclusion VATS sublobectomy had generally better HRQOL and faster recovery of postoperative cough than VATS lobectomy. In addition, the LCQ-MC performed satisfactorily in describing the longitudinal changes in postoperative cough.

Abstract
Cough is a common complication after pulmonary resection. However, the factors associated with cough that develop after pulmonary resection are still controversial. In this study, we used the Simplified Cough Score (SCS) and the Leicester Cough Questionnaire (LCQ) score to investigate potential risk factors for postoperative cough. Between January 2017 and June 2021, we collected the clinical data of 517 patients, the SCS at three days after surgery and the LCQ at two weeks and six weeks after surgery. Then, univariate and multivariate analyses were used to identify the independent risk factors for postoperative cough. The clinical baseline data of the cough group and the non-cough group were similar. However, the cough group had longer operation time and more blood loss. The patients who underwent lobectomy were more likely to develop postoperative cough than the patients who underwent segmentectomy and wedge resection, while the patients who underwent systematic lymph node dissection were more likely to develop postoperative cough than the patients who underwent lymph node sampling and those who did not undergo lymph node resection. When the same lymph node management method was applied, there was no difference in the LCQ scores between the patients who underwent wedge resection, lobectomy and segmentectomy. The lymph node resection method was an independent risk factor for postoperative cough (p < 0.001). Conclusions: Lymph node resection is an independent risk factor for short-term cough after pulmonary resection with video-assisted thoracoscopic surgery, and damage to the vagus nerve and its branches (particularly the pulmonary branches) is a possible cause of short-term cough. The mechanism of postoperative cough remains to be further studied.

Abstract
BACKGROUND Bronchiectasis is a highly heterogeneous chronic airway disease with marked geographic and ethnic variations. Most influential cohort studies to date have been performed in Europe and USA, which serve as the examples for developing a cohort study in China where there is a high burden of bronchiectasis. The Establishment of China Bronchiectasis Registry and Research Collaboration (BE-China) is designed to: (1) describe the clinical characteristics and natural history of bronchiectasis in China and identify the differences of bronchiectasis between the western countries and China; (2) identify the risk factors associated with disease progression in Chinese population; (3) elucidate the phenotype and endotype of bronchiectasis by integrating the genome, microbiome, proteome, and transcriptome with detailed clinical data; (4) facilitate large randomized controlled trials in China. METHODS The BE-China is an ongoing prospective, longitudinal, multi-center, observational cohort study aiming to recruit a minimum of 10,000 patients, which was initiated in January 2020 in China. Comprehensive data, including medical history, aetiological testing, lung function, microbiological profiles, radiological scores, comorbidities, mental status, and quality of life (QoL), will be collected at baseline. Patients will be followed up annually for up to 10 years to record longitudinal data on outcomes, treatment patterns and QoL. Biospecimens, if possible, will be collected and stored at - 80 °C for further research. Up to October 2021, the BE-China has enrolled 3758 patients, and collected 666 blood samples and 196 sputum samples from 91 medical centers. The study protocol has been approved by the Shanghai Pulmonary Hospital ethics committee, and all collaborating centers have received approvals from their local ethics committee. All patients will be required to provide written informed consent to their participation. CONCLUSIONS Findings of the BE-China will be crucial to reveal the clinical characteristics and natural history of bronchiectasis and facilitate evidence-based clinical practice in China. Trial registration Registration Number in ClinicalTrials.gov: NCT03643653.

Abstract
Chronic cough is defined in adults as a cough that lasts for ≥8 weeks. When it proves intractable to standard-of-care treatment, it can be referred to as refractory chronic cough (RCC). Chronic cough is now understood to be a condition of neural dysregulation. Chronic cough and RCC result in a serious, often unrecognized, disease burden, which forms the focus of the current review.The estimated global prevalence of chronic cough is 2-18%. Patients with chronic cough and RCC report many physical and psychological effects, which impair their quality of life. Chronic cough also has a significant economic burden for the patient and healthcare systems. RCC diagnosis and treatment are often delayed for many years as potential treatable triggers must be excluded first and a stepwise empirical therapeutic regimen is recommended.Evidence supporting most currently recommended treatments is limited. Many treatments do not address the underlying pathology, are used off-label, have limited efficacy and produce significant side-effects. There is therefore a significant unmet need for alternative therapies for RCC that target the underlying disease mechanisms. Early clinical data suggest that antagonists of the purinergic P2X3 receptor, an important mediator of RCC, are promising, though more evidence is needed.

Abstract
Cough is an important physiological mechanism to protect the lower airways, but it is also one of the most common symptoms that lead patients to seek medical consultations. Chronic cough, usually defined by cough duration longer than 8 weeks in adults, is prevalent in the community and impairs quality of life in individual patients. There are several characteristics that may differentiate pathologic coughs from protective cough responses, including cough duration, frequency, hypersensitivity, impaired cough suppressibility, or treatment refractoriness. However, the impact of cough, or its perceived severity, is a sum of the patient's experience of coughing and is a factor that may finally define cough as a disease. Social isolation is a major impact of chronic cough, which is now worse due to the coronavirus disease 2019 pandemic and a widespread fear of cough as a source of contagion. Emotional impact and economic impact (medical cost, reduced work productivity, and job loss) are also important complications of chronic cough, and they interact in a vicious cycle, aggravated by social isolation and treatment failures. This paper is a narrative review that aims to address the impact and disease burden of chronic cough in adult patients. We review the literature, but also introduce the findings from recent qualitative interviews and the patients' experiences of the impact and burden of chronic cough and discuss unmet needs in these patients.

Abstract
Introduction Understanding the psychometric properties of health-related quality of life (HRQoL) questionnaires can help inform selection in clinical trials. Our objective was to assess the psychometric properties of HRQoL questionnaires in bronchiectasis using a systematic review and meta-analysis of the literature. Methods A literature search was conducted. HRQoL questionnaires were assessed for psychometric properties (reliability, validity, minimal clinically important difference (MCID) and floor/ceiling effects). Meta-analyses assessed the associations of HRQoL with clinical measures and responsiveness of HRQoL in clinical trials. Results 166 studies and 12 HRQoL questionnaires were included. The Bronchiectasis Health Questionnaire (BHQ), Leicester Cough Questionnaire (LCQ), Chronic Obstructive Pulmonary Disease (COPD) Assessment Test (CAT) and Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) had good internal consistency in all domains reported (Cronbach's α≥0.7) across all studies, and the Quality of Life-Bronchiectasis (QOL-B), St George's Respiratory Questionnaire (SGRQ), Chronic Respiratory Disease Questionnaire (CRDQ) and Seattle Obstructive Lung Disease Questionnaire (SOLQ) had good internal consistency in all domains in the majority of (but not all) studies. BHQ, SGRQ, LCQ and CAT had good test–retest reliability in all domains reported (intraclass correlation coefficient ≥0.7) across all studies, and QOL-B, CRDQ and SOLQ had good test–retest reliability in all domains in the majority of (but not all) studies. HRQoL questionnaires were able to discriminate between demographics, important markers of clinical status, disease severity, exacerbations and bacteriology. For HRQoL responsiveness, there was a difference between the treatment and placebo effect. Conclusions SGRQ was the most widely used HRQoL questionnaire in bronchiectasis studies and it had good psychometric properties; however, good psychometric data are emerging on the bronchiectasis-specific HRQoL questionnaires QOL-B and BHQ. Future studies should focus on the medium- to long-term test–retest reliability, responsiveness and MCID in these HRQoL questionnaires which show potential in bronchiectasis. The psychometric properties of health-related quality of life questionnaires should inform the selection of patient-reported outcomes in bronchiectasis clinical trialshttps://bit.ly/3wQuSrm

Abstract
Background Cough is one of the shared complications after lung surgery. In this study, a prospective analysis was conducted for exploring the risk factors of persistent cough after uniportal video-assisted thoracoscopic pulmonary resection. Methods One hundred thirty-five patients with pulmonary nodules who underwent surgical treatment in the same surgical group from November 2019 to January 2020 were enrolled in this prospective study. The severity of cough and its impact on patients’ quality of life before and after surgery were assessed by the Mandarin Chinese version of the Leicester cough questionnaire (LCQ-MC), and postoperative cough was tested by the cough visual analog scale (VAS) and cough symptom score (CSS). Risk factors of cough after pulmonary resection (CAP) were determined by univariate and multivariate logistic regression analysis. Results The incidence of postoperative cough was 24.4% (33 of 135 patients). Univariate analysis showed that gender (female), the surgical site (upper right), the resection (lobectomy), subcarinal lymph node dissection, postoperative acid reflux, length of hospitalization contributed to the development of CAP resection. Multivariate logistic regression analysis showed that the resection (lobectomy) (OR 3.590, 95% CI: 0.637–20.300, P=0.017), subcarinal lymph node dissection (OR 4.420, 95% CI: 1.342–14.554, P=0.001), postoperative acid reflux (OR 13.55, 95% CI: 3.186–57.633, P<0.001) and duration of anesthesia (over 153 minutes, OR 0.987, 95% CI: 0.978–0.997, P=0.011) were independent risk factors for postoperative cough. Conclusions The application of uniportal video-assisted thoracoscopic techniques to several types of lung surgery are conducive to enhanced recovery after surgery (ERAS). Postoperative cough is related to an ocean of factors, the resection (lobectomy), subcarinal lymph node dissection, postoperative acid reflux, and duration of anesthesia (over 153 minutes) are independent high-risk factors for CAP resection. Trial registration This study was registered on ClinicalTrials.gov (NCT04204148).

Abstract
Background The prevalence of potential risk factors for postoperative cough after thyroidectomy remain unknown. The current study aimed to research postoperative cough in patients undergoing thyroid surgery prospectively. Methods Adult patients who underwent primary thyroid surgery were selected prospectively. Data regarding age, sex, BMI, pathology and surgical procedure were collected and analyzed. The Leicester Cugh Questionnaire (LCQ) was required to be completed by all patients before operation, 2 weeks and 4 weeks after operation. Results There were 1264 patients enrolled in total. Eleven patients with vocal cord paralysis were excluded. In patients with benign disease, postoperative cough occurred in 61 patients, with an prevalence rate of 17. 0% compared to an prevalence rate of 33.1% in patients with malignant disease; the difference was significant. For benign patients, the factors of smoking and operation time were independently related to the occurrence of postoperative cough. For malignant patients, the factors of smoking, operation time, operation extent, and the number of positive nodes at level 6 were independently related to the occurrence of postoperative cough. There was no significant difference regarding the LCQ score in patients with benign or malignant disease at the preoperative and the postoperative 4-week time periods. Patients with malignant disease had a significantly lower LCQ score than patients with benign disease at the postoperative 2-week time point (p = 0.004). Conclusions Patients undergoing thyroid cancer surgery had a higher incidence of postoperative cough and were also associated with a decreased cough-related quality of life. The factors of smoking and operation time were the most important predictors for postoperative cough after thyroidectomy.

Abstract
Background Cough is frequent symptom in sarcoidosis and its impact on patient's quality of life (QoL) has not been adequately addressed so far. Objectives The goal of this study was to determine the significant predictors of cough-specific and generic QoL in sarcoidosis patients. Methods In the prospective study 275 sarcoidosis patients administered Patient Reported Outcomes instruments for measurement of dyspnea (Borg and MRC scales) and fatigue (Fatigue Assessment Scale (FAS) and Daily Activity List (DAL)), as well as patients' QoL (cough-specific Leicester Cough Questionnaire (LCQ) and generic tool - 15D). The LCQ contains 3 domains covering physical, psychological and social aspects of chronic cough. Pulmonary function tests (spirometry and diffusing capacity for carbon monoxide) and serum angiotensin converting enzyme (sACE) were also measured. Results Dyspnea measured by Borg scale and impairment of daily activities determined by DAL instrument as well as sACE were the strongest predictors of all cough-specific QoL domains. Mental aspect of patients' fatigue was significantly correlated with all domains except with psychological LCQ domain. Regarding the generic QoL, the following significant predictors were: dyspnea measured by MRC scale, overall fatigue determined by FAS and physical domain of the LCQ. Conclusion It is important to measure both cough-specific and generic QoL in sarcoidosis patients since they measure different health aspects and their predictors can be different. We demonstrated that physical domain of cough-specific QoL is significant predictor of generic QoL. (Sarcoidosis Vasc Diffuse Lung Dis 2020; 37 (2): 158-168).

Abstract
Background Chronic cough has an important impact on physical, social and psychological aspects. A simple and effective method to assess different aspects of chronic cough severity is required. We aimed to develop a simple, self-completed test, Cough Evaluation Test (CET), to evaluate cough severity and its impact on health. Method The items of preliminary CET were generated based on literature review and clinical practice. Items reduction was conducted by modified Delphi method. Patients with chronic cough were recruited to complete CET, Cough Visual Analog Scales (VAS), Mandarin Chinese version of the Leicester Cough Questionnaire (LCQ-MC), and Cough Symptom Score (CSS). Reassessments were performed at 1 week apart before treatment, and after more than 2 weeks treatments. Concurrent validation, internal consistency, repeatability, responsiveness and the minimal important difference (MID) were determined. Results CET consists of five items with a 5-point Likert scale (1–5 scaling of items, 5–25 score range). The Cronbach’s alpha values for CET was 0.80. CET showed a stronger correlation with LCQ-MC (r = − 0.74) compared to that between LCQ-MC with VAS (r = − 0.61). CET also showed a stronger correlation with VAS (r = 0.70) compared to that between VAS with other measures. Intraclass correlation coefficients for CET was 0.84. In patients undergoing treatment, CET scores significantly changed (p < 0.0001). The MID of CET was 2. Conclusion Cough Evaluate Test is a reliable, valid and responsive tool to simply evaluate impact of cough on physical, social and psychological aspects.

Abstract
BACKGROUND A higher incidence of Arnold nerve reflex (ANR) has been observed in patients with chronic cough. However, the different ANR response in various causes of chronic cough remains unclear. Furthermore, it is unknown whether ANR will change after effective treatment. METHODS Patients with chronic cough were enrolled in the Guangzhou Institute of Respiratory Health. The causes of chronic cough were diagnosed via a validated management algorithm. Patients underwent an assessment of ANR response before and after 1 month of etiologic treatment. RESULTS A total of 127 patients with chronic cough and 55 healthy control subjects were enrolled. The positive response, defined as cough-only ANR or urge-to-cough (UTC), was present in 14.8% of patients with cough variant asthma (CVA), 11.1% of patients with upper airway cough syndrome, 15.4% of patients with gastroesophageal reflex related cough (GERC), 4.8% of patients with eosinophilic bronchitis, and 26.9% of patients with unexplained cough (UC). No ANR or UTC was found in the healthy control subjects. The incidence of the positive response was higher in subjects with CVA, GERC, and UC compared with healthy control subjects (all P < .05). No difference was observed among the different causes of chronic cough (all P > .05). After 1 month of treatment, 87.5% of patients identified with a positive response changed to a negative response. In a subgroup analysis, an increased cough sensitivity to capsaicin was found in the patients with a positive response compared with the patients with a negative response (P < .05). CONCLUSIONS A positive ANR appears to be a sign of vagal hypersensitivity and can be reversed after effective treatment of chronic cough. However, although various causes of chronic cough share a similar feature of an elevated ANR response in a minority of patients, there appears to be limited usefulness in assessing ANR because it does not appear to be a valid predictor of etiology of chronic cough or outcome of treatment.

Abstract
Background In this study, we investigated the relationship between chronic cough and clinicopathological features in postoperative patients with non‐small cell lung cancer (NSCLC) and evaluated the effectiveness of acupuncture therapy for the treatment of postoperative chronic cough in patients with NSCLC. Methods We retrospectively evaluated 171 patients with NSCLC who received lobectomy at our center between September 2017 and February 2018. The Mandarin Chinese version of the Leicester Cough Questionnaire (LCQ‐MC) was used to evaluate the degree of cough in patients. Postoperative cough was assessed by a visual analog scale (VAS). Results The total LCQ‐MC score for the whole group was 19.79 ± 0.53 before surgery and 18.40 ± 0.70 after surgery (p < 0.001). Logistic regression analysis showed that right lung cancer, difficult airway, acute cough and history of COPD were independent predictors of chronic cough. Of the 68 patients diagnosed with chronic cough, 41 received acupuncture therapy (acupuncture therapy group), and 27 received no acupuncture therapy (no therapy group). No significant difference was found between the two groups in terms of their LCQ‐MC scores at eight weeks after surgery (p = 0.756). However, the acupuncture therapy group had a significantly higher LCQ‐MC score than the no therapy group at 10 weeks after surgery (p = 0.002). Conclusions Right lung cancer, difficult airway, acute cough, and history of COPD are independent predictors of chronic cough after surgery. For patients with chronic cough, acupuncture therapy can shorten the recovery time and improve quality of life after surgery.

Abstract
Background Cough is one of the most common symptoms in general and pulmonary medicine with profound negative impact on health-related quality of life (HRQL). The Leicester Cough Questionnaire (LCQ) is a validated HRQL questionnaire, yet a validated German version of the LCQ is not available and it has never been tested in a cohort with sarcoidosis. Objectives To translate the LCQ into German and determine its psychometric properties. Methods The LCQ was translated in a forward-backward approach. Structured interviews in sarcoidosis patients were performed. Subsequently, sarcoidosis patients were asked to answer the German LCQ and comparative questionnaires. Distribution properties, item difficulty, concurrent validity, Rasch model fit and internal consistency of the German LCQ were determined. Results 200 patients with sarcoidosis were included. We provide evidence for reliability, unidimensionality and internal consistency. However, only a moderate correlation with general and respiratory-specific HRQL questionnaires, no Rasch model fit could be shown. Skewed responses caused by floor effects were detected. Conclusion We demonstrate that the German LCQ is valid and reliable and its psychometric properties fulfil the standards required for its use in clinical settings as well as in interventional trials.

Abstract
Background Cough is a common respiratory complication in non-small cell lung cancer (NSCLC) patients after surgery. Previous studies have proposed a number of risk factors for postoperative cough; however, these studies are mainly based on traditional thoracotomies and tend to lack adequate objective assessment methods. The purpose of this study was to identify the risk factors of cough in NSCLC patients after video-assisted thoracoscopic surgery (VATS) using the Leicester Cough Questionnaire in Mandarin Chinese (LCQ-MC) to evaluate postoperative cough. Methods A total of 198 NSCLC patients were enrolled. Overall, 91 patients (46.0%) developed cough after VATS, and 73 patients remained cough after 1 month. Univariate and multivariate logistic regression analyses were performed to identify the independent risk factors of postoperative cough. Results The independent factors of postoperative cough included female sex [odds ratio (OR) 2.399, 95% confidence interval (CI): 1.260-4.565, P=0.008], duration of anesthesia (over 164 minutes; OR 2.810, 95% CI: 1.368-5.771, P=0.005), resection of the lower paratracheal nodes (OR 3.697, 95% CI: 1.439-9.499, P=0.007), and resection of the subcarinal nodes (OR 4.175, 95% CI: 1.203-14.495, P=0.024). The follow-up LCQ-MC total score after 1 month (18.00±1.80) was significantly higher than the postoperative total score (16.35±2.26; P=0.004). Conclusions Female sex, duration of anesthesia over 164 minutes, lower paratracheal node resection and subcarinal node resection were independent risk factors related to cough in NSCLC patients after VATS. In addition, the LCQ-MC performed satisfactorily in describing the longitudinal changes in cough symptoms.

Abstract
Background There are no validated and reliable cough‐specific instruments to assess health‐related quality of life with respect to postoperative cough in non‐small cell lung cancer (NSCLC) patients. We used the Leicester Cough Questionnaire in Mandarin‐Chinese (LCQ‐MC) and investigated the validity, reliability, and repeatability of this instrument. Methods A total of 130 NSCLC patients (average age 58.75 ± 9.43 years, 65 men, 65 women) completed the LCQ‐MC, cough Visual Analogue Scale (VAS), Cough Symptom Score (CSS), Hospital Anxiety and Depression Scale (HADS), and Medical Outcomes Study 36‐item Short‐Form Health Survey (SF‐36). Forty patients completed the LCQ‐MC again one week later. Concurrent validity, internal consistency, and repeatability were assessed. Results Analyses of concurrent validity showed significant correlations between the LCQ‐MC and the cough VAS (r = −0.488 to −0.660) and CSS (r = −0.495 to −0.601). The corresponding domains of the LCQ‐MC and the SF‐36 exhibited moderate correlations (r = 0.421–0.432). However, there was no significant correlation between the LCQ‐MC and the HADS (P > 0.05). Internal consistency was acceptable (Cronbach's α of 0.74–0.90). Test‐retest reliability was high (intraclass correlation coefficients of 0.89–0.95). Conclusion The LCQ‐MC is a reliable, valid instrument for assessing postoperative cough in NSCLC patients.

Abstract
PURPOSE The purpose of this study was to translate and culturally adapt the Leicester Cough Questionnaire into Swedish and to test the validity and reliability of the Swedish version, in patients with chronic obstructive pulmonary disease. METHODS The original Leicester Cough Questionnaire was translated into Swedish by a method, which followed an established forward-backward procedure, including cross-cultural adaptation and pretest. To test the validity of the final version of Leicester Cough Questionnaire in Swedish, the St George's Respiratory Questionnaire and the COPD Assessment Test were used (n =112) and to test reliability, the questionnaire was repeated (n = 86). RESULTS The Leicester Cough Questionnaire in Swedish showed proof of construct validity and proof of internal consistency (Cronbach's alpha coefficient 0.97). All domains and total scores had good-excellent test-retest reliability (intra-class correlation coefficient 2,1 > 0.94). The standard error of measurement, (standard error of measurement percent), for the Leicester Cough Questionnaire in Swedish was 0.84 (5.15%). The smallest real difference, (smallest real difference percent), derived from cross sectional standard error of measurement was 2.33 (14.25%). The Bland-Altman plot indicated no systemic change in the mean. CONCLUSION The Leicester Cough Questionnaire in Swedish is a valid and reliable instrument to measure health-related quality of life in patients with chronic obstructive pulmonary disease and can be used in clinical settings. Implications for Rehabilitation The Leicester Cough Questionnaire, has been translated into Swedish, following an established forward-backward procedure, including cross-cultural adaptation The Swedish version of the Leicester Cough Questionnaire, is a valid, reliable instrument for measuring health-related quality of life regarding cough in patients with chronic obstructive pulmonary disease The Swedish version of the Leicester Cough Questionnaire is easy to administer and can be used in clinical and rehabilitation settings and for research purposes The absolute reliability presented at group and individual levels to indicate a real improvement is an advantage to assist when interpreting a clinically relevant difference.

Abstract
BACKGROUND The Mandarin Chinese version of the Leicester Cough Questionnaire (LCQ-MC) is a symptom specific questionnaire designed to assess the impact of cough severity, a major symptom of postoperative patients undergoing lung resection is cough. The aim of this study is to validate the LCQ-MC in patients with lung operation. METHODS Totally 121 patients undergone the lung operation of single medical team, from September 2015 to April 2016 in the Thoracic Surgery Department of West China hospital Sichuan University, were investigated by LCQ-MC before and after operation. We analyzed and calculated the preoperative and postoperative scores of LCQ-MC and Cronbach α. RESULTS ①The mean LCQ-MC score in preoperative (19.57±1.73) was significant higher than postoperative (17.71±2.72) (P=0.041). ②The Cronbach α in preoperative (0.87) and postoperative (0.89) was significant higher than 0.7. ③The preoperative scores of LCQ-MC (19.31±1.84) was significantly lower in postoperative cough group than in without postoperative cough group (19.97±1.46) (P=0.038). The postoperative scores of LCQ-MC (16.67±2.91) was significantly lower in postoperative cough group than in without postoperative cough group (19.30±1.32) (P=0.001). ④There was no statistical difference (P=0.936) between postoperative LCQ-MC score (17.75±2.51) in lobectomy group and non-lobectomy group (17.79±3.04). CONCLUSIONS The LCQ-MC can assess the condition of cough after thoracoscopic surgery in patients with pulmonary disease.

Abstract
Health-related quality of life or health status is significantly impaired in bronchiectasis. There is a paucity of brief, simple-to-use, disease-specific health status measures. The aim of this study was to develop and validate the Bronchiectasis Health Questionnaire (BHQ), a new health status measure that is brief and generates a single overall score.Patients with bronchiectasis were recruited from two outpatient clinics, during a clinically stable stage. The development of the questionnaire followed three phases: item generation and item reduction using Rasch analysis, validation, and repeatability testing. The BHQ was translated into 11 languages using standardised methodology.206 patients with bronchiectasis completed a preliminary 65-item questionnaire. 55 items were removed due to redundancy or poor fit to the Rasch model. The final version of the BHQ consisted of 10 items. Internal consistency was good (Cronbach's α=0.85). Convergent validity of the BHQ with the St George's Respiratory Questionnaire was high (r= -0.82; p<0.001) and moderate with lung function (forced expiratory volume in 1 s % predicted r= -0.27; p=0.001). There was a significant association between BHQ scores and number of exacerbations of bronchiectasis in the last 12 months (p<0.001), hospital admissions (p=0.001) and computed tomography scan bronchiectasis pulmonary lobe counts (p<0.001). BHQ scores were significantly worse in patients with sputum bacterial colonisation versus no colonisation (p=0.048). The BHQ was highly repeatable after 2 weeks (intraclass correlation coefficient 0.89).The BHQ is a brief, valid and repeatable, self-completed health status questionnaire for bronchiectasis that generates a single total score. It can be used in the clinic to assess bronchiectasis from the patient's perspective.

Abstract
OBJECTIVES To investigate the minimal clinically important differences (MCIDs) of the Thai version of the Leicester Cough Questionnaire (LCQ-T) in patients with subacute and chronic cough. METHODS Patients with cough for 3 or more weeks were recruited from outpatient clinics. They self-completed the LCQ-T at an initial evaluation and repeated the LCQ-T with a Global Rating of Change scale at follow-up. For the anchor-based method, the MCID was defined as a change in the LCQ scores that corresponded to the smallest improvement in Global Rating of Change score (+2 to +3). For distribution-based methods, the MCIDs were estimated from the standard error of measurement and a half and one-third of the SD of the LCQ score changes from baseline to follow-up. RESULTS A total of 107 patients were included. The causes of cough were postinfectious cough/bronchitis (35.5%), asthma (20.6%), rhinosinusitis (16.8%), bronchiectasis (17.8%), and chronic obstructive pulmonary disease (9.3%). The anchor-based method yielded MCIDs of 1.1, 0.4, 0.4, and 0.4 for the total, physical, psychological, and social domains, respectively. The distribution-based method using standard error qof measurement yielded MCIDs of 0.8, 0.3, 0.3, and 0.3, whereas those using a half SD yielded MCIDs of 2.0, 0.6, 0.8, and 0.8 and those using one-third SD yielded MCIDs of 1.4, 0.4, 0.5, and 0.5 for the total, physical, psychological, and social domains, respectively. CONCLUSIONS The MCIDs of the LCQ-T for subacute and chronic cough are 1.1, 0.4, 0.4, and 0.4 for the total, physical, psychological, and social domains, respectively. These estimates should be useful in making meaningful interpretations of the changes in quality of life because of cough.

Sputum matrix metalloproteinase-8 and -9 and tissue inhibitor of metalloproteinase-1 in bronchiectasis: clinical correlates and prognostic implications. Respirology 2015; 20:1073-81. [PMID: 26122009 DOI: 10.1111/resp.12582] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2015] [Revised: 04/16/2015] [Accepted: 04/17/2015] [Indexed: 01/11/2023]
Abstract
BACKGROUND AND OBJECTIVE The triplet of airway infection, inflammation and bronchial wall destruction associated with excessive matrix metalloproteinases (MMP) release and imbalance of tissue inhibitor metalloproteinase-1 (TIMP-1) is implicated in bronchiectasis. We sought to determine the associations between sputum MMP (MMP-8, MMP-9) and TIMP-1 and the severity of bronchiectasis; the utility of MMP in predicting risks of future bronchiectasis exacerbations (BE); and the changes in MMP levels during BE. METHODS We recruited 102 patients with stable bronchiectasis and 22 healthy subjects. For bronchiectasis patients, baseline measurements consisted of sputum inflammation and MMP measurements, bacterial culture, spirometry and chest high-resolution computed tomography (HRCT). Bronchiectasis patients were followed up for 1 year to determine the frequency of BE. Changes in MMP levels during BE were assessed in 36 bronchiectasis patients. RESULTS Sputum MMP-8, MMP-9 and MMP-9/TIMP-1 ratio in bronchiectasis patients were significantly increased compared with healthy subjects. MMP-8 and MMP-9 levels, but not TIMP-1, were positively correlated with clinical measures, including HRCT scores, spirometry and Bronchiectasis Severity Index. Seventy-nine bronchiectasis patients were included in survival analyses of BE. Lower levels of baseline MMP-9 were associated with reduced risks of and a longer time to the first BE during follow-up. MMP-8 and MMP-9, but not TIMP-1 or MMP-9/TIMP-1 ratio, were significantly heightened during BE. CONCLUSIONS Sputum MMP might be useful biomarkers for the assessment of bronchiectasis severity and the prediction of future risks of BE. Our results provide the rationales for the future clinical application of MMP inhibitors.

Abstract
BACKGROUND Current status of Pseudomonas aeruginosa (PA) infection in clinically stable bronchiectasis in mainland China remains unclear. OBJECTIVE To compare the inflammation and lung function impairment in bronchiectasis patients isolated or infected with PA, potentially pathogenic microorganisms (PPMs) and commensals, and to identify factors associated with PA isolation and infection. METHODS Patients with steady-state bronchiectasis and healthy subjects were recruited. Peripheral blood and sputum were sampled to determine inflammatory markers and bacterial loads in steady-state bronchiectasis and health. Spirometry and diffusing capacity were also measured. RESULTS We enrolled 144 bronchiectasis patients and 23 healthy subjects. PA isolation and infection accounted for 44 and 39 patients, who demonstrated significant inflammatory responses and markedly impaired spirometry, but not diffusing capacity, compared with healthy subjects and patients isolated with other PPMs and commensals (all P<0.05). Except for heightened sputum inflammatory responses, there were no notable differences in serum inflammation and lung function as with the increased density of PA. Female gender [odds ratio (OR): 3.10 for PA isolation; OR: 3.74 for PA infection], 4 or more exacerbations within 2 years (OR: 3.74 for PA isolation, OR: 2.95 for PA infection) and cystic bronchiectasis (OR: 3.63 for PA isolation, OR: 4.47 for PA infection) were the factors consistently associated with PA isolation and infection. CONCLUSIONS PA elicits intense inflammation and lung function impairment in steady-state bronchiectasis. The density of PA does not correlate with most clinical indices. PA infection is associated with females, frequent exacerbations and cystic bronchiectasis.

Abstract
BACKGROUND The profiles of 6-minute walk distance (6MWD) in adults with clinically stable bronchiectasis in Chinese adult patients with bronchiectasis are unclear. OBJECTIVES To delineate the 6MWD by stratification of clinical indices, and to investigate the factors associated with reduced 6MWD in Chinese adults with clinically stable bronchiectasis. METHODS We recruited 141 adult bronchiectasis patients (mean age: 44.3 ± 13.9 years). Demography, radiology, spirometry, diffusing capacity, etiology, sputum bacteriology, modified Medical Research Council dyspnea scale (MMRC) and quality of life were assessed. The safety profile of the measurement was also examined. RESULTS Lower levels of 6MWD were associated with older age (>50 years), higher HRCT total score, presence of cystic bronchiectasis, bilateral bronchiectasis, reduced diffusing capacity, higher MMRC score, and higher SGRQ scores. Correlation coefficients between 6MWD and spirometry and quality of life scores were different in patients with 6MWD higher and lower than lower limit of normal. DLCO being less than 80% predicted (OR = 3.13, 95% CI: 1.32-7.43, P = 0.01) and MMRC scale between 1 and 4 (OR = 6.42, 95% CI: 2.27-18.18, P < 0.01) were the factors associated with 6MWD being less than the lower limit of normal (80% predicted value). No severe adverse events were reported. CONCLUSION The 6MWD could be safely measured in adult patients with bronchiectasis and is poorly associated with clinical parameters. DLCO less than 80% predicted and higher MMRC scale are independent predictors of 6MWD below the lower limit of normal. Our findings will provide a reference for management of bronchiectasis patients in mainland China.
