  • A Pilot Study of A SimpleManagement Strategy for ChronicCough

    Objective Using a simple management strategy to investigate the etiologic spectrum of chronic cough in Chengdu city and its suburbs. Methods Chronic cough patients were randomly recruited fromthe outpatient clinic of Sichuan Provincial People ’s Hospital between July 2011 to May 2012. A conception of “Chronic Airway Inflammatory Cough Syndrome, CAICS”was established including several common causes of cough such as cough variant asthma ( CVA) , eosinophilic bronchitis ( EB) , atopic cough ( AC) , and atypical chronic bronchitis. Based on CAICS, a simplified suspected diagnosis procedure of chronic cough was conducted. Patients were empirically treated. Etiology and efficiency of chronic cough was analyzed. Results A total of 148 patients of chronic cough were recruited. The mean age was ( 43. 0 ±13. 0) years old. There were 72 male and 76 female patients with mean ages of ( 39. 7 ±10. 7) and ( 45. 0 ± 14. 2) years old respectively. The males were younger than the females ( P lt; 0. 05) . There was 96. 6% ( 143/148) of patients suspectedly diagnosed and 3.4% ( 5/148) patients were undiagnosed. The suspected causes of these chronic cough patients were as follows, ie. CAICS ( 57. 5% ) , upper airway cough syndrome ( UACS, 21. 5%) , gastroesophageal reflux cough ( GERC, 9. 1% ) , and others ( 8. 4% ) . A single possible cause was found in 95 patients ( 64.1% ) , two possible causes in 41 patients ( 27. 7% ) , and three possible causes in 3 patients( 2. 0% ) . 12.2% of chronic cough patients were combined with allergic rhinitis ( AR) . Among the diseases, CVA, CAICS and UACS were disposed to coexist with AR. The overall efficiency of empiric management strategy of chronic cough was 83. 7% .Conclusions The etiological spectrum of chronic cough in Chengdu acquired by this strategy was generally consistent with previous findings in China.The three most important causes of chronic cough in Chengdu were CAICS, UACS and GERC. This strategy was simple, effective, economic and feasible. It could be a primary management for chronic cough in some hospital.

  • Chronic cough and risk of cerebrovascular disease: a prospective cohort study

    Objective To explore the association between cough patterns and cerebrovascular disease risk, and to provide epidemiological evidence for the early diagnosis and prevention of cerebrovascular disease. Methods During the period from 2010 to 2012 in Guizhou Province, a multi-stage proportional stratified cluster sampling method was used to recruit people with the inclusion criteria of the study into a cohort and a baseline questionnaire for demographic information, lifestyle, and disease history was administered. The incidence of cerebrovascular disease was followed up from 2016 to 2020. Results A total of 4804 subjects were followed up, and 4589 (53.5% were female) subjects were enrolled in final investigation. Compared with non-chronic cough group, there was no statistical significance in the risk of cerebrovascular diseases (P>0.05), however, chronic cough (the risk ratio was 2.00 and the 95% confidence interval ranged from 1.08 to 3.69) was twice as likely to develop cerebrovascular disease as non-cough. Conclusions People with chronic cough are more likely to develop cerebrovascular disease than people without cough. More attention to the management and control of cough should be paid to avoid chronic cough, so as to reduce the risk of cerebrovascular diseases.

  • Feature Extraction for Cough-sound Recognition Based on Principle Component Analysis and Non-uniform Filter-bank

    Cough recognition provides important clinical information for the treatment of many respiratory diseases. A new Mel frequency cepstrum coefficient (MFCC) extracting method has been proposed on the basis of the distributional characteristics of cough spectrum. The whole frequency band was divided into several sub-bands, and the energy coefficient for each band was obtained by method of principle component analysis. Then non-uniform filter-bank in Mel frequency is designed to improve the extracting process of MFCC by distributing filters according to the spectrum energy coefficients. Cough recognition experiment using hidden Markov model was carried out, and the results showed that the proposed method could effectively improve the performance of cough recognition.

  • Correlation between Periostin, IL-33, and chronic cough after thoracoscopic lobectomy in patients with CABG combined with lung cancer

    ObjectiveTo study the correlation between Periostin, interleukin-33 (IL-33), and chronic cough after thoracoscopic lobectomy in patients with coronary artery bypass grafting (CABG) combined with lung cancer. Methods A total of 102 lung cancer patients at Tianjin Chest Hospital from January 2022 to January 2024 were prospectively enrolled, and they were divided into a chronic cough group and a non chronic cough group based on whether chronic cough occurred after surgery. Serum levels of Periostin and IL-33 were measured on the 1st, 7th, and 14th days post-lobectomy. The Pearson method was employed to analyze the correlation between Periostin and IL-33 levels and the severity of cough. Univariate and multivariate logistic regression analyses were conducted to identify factors influencing the occurrence of chronic cough. Additionally, ROC curve analysis was utilized to assess the potential value of serum Periostin and IL-33 levels in predicting postoperative chronic cough. Results In patients with chronic cough, the peripheral blood Periostin and IL-33 levels measured on days 7 and 14 were significantly higher than those in patients with non-chronic cough, and the interactions between the two groups and at different time points were significant (P<0.001). The degree of cough was positively correlated with the levels of Periostin and IL-33 on days 7 and 14 (P<0.05), but had no significant correlation with the levels on day 1 (P>0.05). In patients with lung cancer, after thoracoscopic lobectomy, Periostin [OR=1.619, 95%CI (1.295, 2.025)] and IL-33 [OR=1.831, 95%CI (1.216, 2.758)] on day 7 and Periostin on day 14 [OR=1.952, 95%CI (1.306, 2.918)] and IL-33 [OR=1.742, 95%CI (1.166, 2.603)] were identified as risk factors for chronic cough. ROC curve analysis showed that the sensitivity of Periostin on day 7 was 69.05%, the specificity was 71.67%, and the AUC was 0.756 [95%CI (0.616, 0.893)]. The sensitivity of Periostin on day 14 increased to 71.43% and the specificity was 76.67%, AUC was 0.762 [95%CI (0.633, 0.898)]. At the same time, the critical value of IL-33 on day 7 was 45.03 pg/mL, the sensitivity and specificity were both 83.33%, the AUC was 0.884 [95%CI (0.789, 0.980)], and the critical value of IL-33 on day 14 was 56.01 pg/mL, the sensitivity was 85.71%, the specificity was 80.00%, and the AUC was 0.899 [95%CI (0.799, 0.999)]. Further regression analysis showed that the sensitivity was 95.24%, the specificity was 95.00%, and the AUC reached 0.993 [95%CI (0.979, 1.000)]. Conclusion Periostin and IL-33 levels, measured at various time points, are abnormally elevated following thoracoscopic lobectomy in patients with combined CABG and lung cancer. These levels significantly correlate with cough severity. Given their predictive potential for chronic cough, these markers are deemed valuable biomarkers.

  • Exploring predictive factors for extubation in mechanically ventilated patients with moderate to severe traumatic brain injury

    ObjectiveTo explore the predictive factors for extubation in mechanically ventilated patients with moderate to severe traumatic brain injury (TBI). MethodsMechanically ventilated adult patients with moderate to severe brain injuries admitted to the People’s Hospital of Hunan province were selected between April 2020 and March 2022. The general data, neurological function and airway protective ability of the patients were collected. The patients were divided into successful extubation and failed extubation groups based on extubation outcomes. The differences in various indicators between the two groups were compared. Univariate and multivariate logistic regression analyses were conducted to determine the influencing factors for tracheal tube extubation in patients with moderate to severe TBI. Receiver operating characteristic (ROC) curves were plotted to analyze the predictive value of each indicator for extubation in TBI patients. ResultsA total of 263 patients with moderate to severe TBI were included in the analysis, with 183 patients in the successful extubation group and 80 patients in the failed extubation group. The successful extubation group had higher Glasgow coma scale (GCS) and cough peak flow (CPF) compared to the failed extubation group. The incidence of ventilator-associated pneumonia (VAP), duration of mechanical ventilation, length of ICU stay, and length of hospital stay were all lower in the successful extubation group. Univariate and multivariate logistic regression analyses showed that the predictive factors for tracheal tube extubation in patients with moderate to severe TBI were CPF and GCS at the time of extubation. Adjusting for confounding factors, every 1 L/min increase in CPF at the time of extubation reduced the risk of extubation failure by 2% [odds ratio (OR) = 0.98, 95% confidence interval (CI) 0.97 - 0.99], and every 1-point increase in GCS reduced the risk of extubation failure by 12% (OR = 0.88, 95%CI 0.79 - 0.98). ROC curve analysis showed that CPF, GCS, GCS eye, and GCS motor had predictive value for tracheal tube extubation in patients with moderate to severe TBI. When patients simultaneously met the criteria of GCS≥8 (GCS motor≥5, GCS eye≥3) and CPF ≥68.5 L/min, the diagnostic value for predicting successful extubation was highest, with an area under the ROC curve of 0.946 (95%CI 0.917 - 0.975), sensitivity of 0.850, and specificity of 0.907. ConclusionCPF ≥ 68.5 L/min and GCS ≥ 8 have clinical guiding value for successful extubation in mechanically ventilated patients with moderate to severe traumatic brain injury.

  • Analysis of factors influencing chronic cough following pulmonary surgery

    Objective To analyze the risk factors for chronic cough following pulmonary surgery in patients with non-small cell lung cancer (NSCLC). Methods A retrospective analysis was conducted on 427 NSCLC patients who underwent pulmonary surgery in the Department of Thoracic Surgery, The First Affiliated Hospital of the University of Science and Technology of China, between January 2021 and June 2023. Patients were categorized into a chronic cough group (103 patients) and a non-chronic cough group (324 patients) based on the presence of cough at 8 weeks post-surgery. A comparative analysis was performed between the two groups, considering gender, age, smoking history, comorbidities, preoperative pulmonary function indicators, pleural adhesion, anesthesia duration, surgical site, operative techniques, lymph node dissection methods, tumor maximum diameter, and postoperative chest tube duration. Factors showing statistical significance in univariate analysis underwent multivariate logistic regression analysis. Results Among the 427 patients undergoing pulmonary surgery, there were 165 males and 262 females, with an average age of (59.93±12.11) years. The incidence of chronic cough was 24.12%. Univariate analysis revealed significant differences in smoking history, preoperative pulmonary function indicators, pleural adhesion, anesthesia duration ≥135.5 minutes, surgical site, operative techniques, lymph node dissection methods, tumor maximum diameter, and postoperative chest tube duration (P<0.05). Multivariate logistic regression analysis indicated that the surgical site (right upper lung), operative techniques (lobectomy), lymph node dissection, and anesthesia time ≥135.5 minutes were independent risk factors for chronic cough following pulmonary surgery. ConclusionPatients undergoing right upper lung surgery, lobectomy, lymph node dissection, and experiencing anesthesia duration ≥135.5 minutes are at a higher risk of developing chronic cough post-pulmonary surgery.

  • The simple decision tree for etiologic diagnosis of chronic cough based on the Modified Cough Assessment Test

    Objective To compare the clinical characteristics of chronic cough, and to establish the Modified Cough Assessment Test and the simple decision tree to improve the efficacy of etiologic diagnosis. Methods Patients with chronic cough consulted in Tongji Hospital between October 2021 and August 2023 were enrolled in our study. The patients with identified single cause were divided into 3 groups accordingly: corticosteroid-responsive cough (CRC), upper airway cough syndrome (UACS) and gastroesophageal reflux-related cough (GERC). And the characteristics of chronic cough in different causes were assessed and compared by cough questionnaires. Independent predictors of various causes were identified by multivariate logistic regression analysis and used to establish the Modified Cough Assessment Test (MCET) and to construct the simple decision tree. Results A total of 358 patients were enrolled, including 201 with CRC (56.1%), 125 with UACS (34.9%) and 32 with GERC (8.94%). "Cough with wheezing or chest tightness" (OR=3.222, 95%CI 2.144 - 4.843, P<0.001), "Cough with daytime heaviness and nighttime lightness" (OR=1.755, 95%CI 1.264 - 2.435, P<0.001), and "Cough with acid reflux, heartburn or indigestion" (OR=15.580, 95%CI 5.894 - 41.184, P<0.001) were independent factors for each group, respectively. The area under ROC curve for classification of CRC, UACS and GERC were 0.871, 0.840 and 0.988 for MCET, which were better than those of Leicester Cough Questionnaire (LCQ) (0.792, 0.766 and 0.913) and Cough Evaluation Test (CET) (0.649, 0.691 and 0.580). The accuracy of the simple decision tree for the differential diagnosis of chronic cough was 77.4%. Conclusion The simple decision tree based on the Modified Cough Evaluation Test is a simple and effective method of etiologic diagnosis of chronic cough, which can be used as a tool to improve the efficacy of clinical diagnosis in outpatient settings.
