Objective To analyze the clinicopathological characteristics of thymoma patients and the influencing factors for prognosis. Methods Thymoma patients who received treatment in Sichuan Cancer Hospital from March 2015 to March 2021 were collected. Clinical data of the patients were analyzed using Kaplan-Meier and Cox regression analyses. Results A total of 177 patients were included. There were 89 males and 88 females aged 17-88 (52.3±13.0) years, including 160 surgical patients and 17 non-surgical patients. There were 160 patients survived, 17 died of thymoma, and 5 had recurrence and metastasis. Overall, the 1-year, 3-year and 5-year progression-free survival rates were 94.4%, 88.7%, 88.1%, respectively; the 1-year, 3-year and 5-year overall survival rates were 94.9%, 91.5%, 91.0%, respectively. The Kaplan-Meier analysis showed that World Health Organization classification, clinical symptoms, Masaoka-Koga staging, treatment methods and surgery were statistically associated with progression-free survival; clinical symptoms, age, treatment methods and surgery were statistically associated with overall survival (P<0.05). Patients with younger age (P=0.018), without clinical symptoms (P=0.039), and with surgical treatment (P=0.004) had higher overall survival rates; those patients undergoing surgery had a higher progression-free survival rate (P=0.002). Conclusion Age, clinical symptoms and surgical treatment are independent factors influencing the prognosis of patients with thymoma.
ObjectiveTo retrospectively collect data on patients with stable chronic obstructive pulmonary disease (COPD), and explore the current status of medication adherence and its main influencing factors in China.MethodsAccording to the principle of convenience, 293 patients with COPD were enrolled in 16 tertiary hospitals located in Nanjing, Hefei, Wuhu, Xuzhou, and Chuzhou. The status quo and influencing factors of medication adherence in COPD patients were identified and analyzed by using the 8-item Morisky Drug Compliance Scale, Beliefs about Medicines Questionnaire, Hospital Anxiety and Depression Scale, General Self-Efficacy Scale, and modified British Medical Research Council. The analysis was based on the framework provided by the WHO’s "five-dimensional determinants" and the mathematical relationship was demonstrated through sequential logistic regression analysis. ResultsThe medication adherence of the target population is 11.95%. A higher socio-economic status [odds ratio (OR) 0.30, 95% confidential interval (CI) 0.10 - 0.91], patients’ general beliefs about the medication utility (OR 0.29, 95%CI 0.17 - 0.50) and overuse (OR 0.30, 95%CI 0.16 - 0.55) were associated with a lower chance of being adherent in patients with COPD. While disease severity (OR 2.01, 95%CI 1.11 - 3.64) and types of drug use (OR 1.91, 95%CI 1.07 - 3.41) presented opposite results. ConclusionsMedication adherence in domestic patients with COPD is not satisfactory at the present stage. Effective ways to improve patients’ medication adherence and quality of life could be proposed from the national, living environment and individual three dimensions.
Objective To evaluate the surgical efficacy of unilateral pneumonectomy for the treatment of tuberculous destroyed lung, analyze the causes of severe postoperative complications, and explore clinical management strategies. Methods A retrospective analysis was conducted on the clinical data of patients with tuberculous destroyed lung who underwent unilateral pneumonectomy at the Public Health Clinical Center of Chengdu from 2017 to 2023. Postoperative severe complications were statistically analyzed. Patients were divided into a non-severe complication group and a severe-complication group, and the causes, management, and outcomes of complications were analyzed. Results A total of 134 patients were included, comprising 69 males and 65 females, with a mean age of 17-73 (40.43±12.69) years. There were 93 patients undergoing left pneumonectomy and 41 patients undergoing right pneumonectomy. Preoperative sputum smear was positive in 35 patients, all of which converted to negative postoperatively. There were 58 patients with hemoptysis preoperatively, and none experienced hemoptysis postoperatively. Postoperative incisional infection occurred in 8 (5.97%) patients, and postoperative pulmonary infection in 26 (19.40%) patients. Severe postoperative complications occurred in 17 (12.69%) patients, including empyema in 9 (6.72%) patients, bronchopleural fistula with empyema in 1 (0.75%) patient, severe pneumonia in 3 (2.24%) patients, postpneumonectomy syndrome in 1 (0.75%) patient, chylothorax in 1 (0.75%) patient, ketoacidosis in 1 (0.75%) patient, and heart failure with severe pneumonia in 1 (0.75%) patient. Perioperative mortality occurred in 2 (1.49%) patients, both of whom underwent right pneumonectomy. Multivariate logistic regression analysis revealed that a history of ipsilateral thoracic surgery, concomitant Aspergillus infection, and greater blood loss were independent risk factors for severe complications following unilateral pneumonectomy for tuberculous destroyed lung (P<0.05). ConclusionUnilateral pneumonectomy for patients with tuberculous destroyed lung can significantly improve the clinical cure rate, sputum conversion rate, and hemoptysis cessation rate. However, there is a certain risk of severe perioperative complications and mortality, requiring thorough perioperative management and appropriate management of postoperative complications.
Objective To analyze the benign-malignant outcomes of pulmonary nodules in surgical patients and their influencing factors, and provide evidence and ideas for optimizing and improving the integrated management model of pulmonary nodules. Methods From October to December 2023, a convenience sampling method was used to select patients who underwent lung surgery at West China Hospital, Sichuan University between July 2022 and June 2023 for this study. The malignancy rate of postoperative pathological results of pulmonary nodules and its influencing factors were analyzed using univariate analysis and multiple logistic regression. Results A total of 4600 surgical patients with pulmonary nodules were included, with a malignancy rate of 88.65% (4078/4600) and a benign rate of 11.35% (522/4600). Univariate analysis showed significant differences in malignancy rates among different genders, ages, methods of pulmonary nodule detection, and smoking histories (P<0.05); however, no significant difference was found regarding place of birth or family history of lung cancer (P>0.05). Multiple logistic regression analysis indicated that females [odds ratio (OR)=1.533, 95% confidence interval (CI) (1.271, 1.850)], older age groups [61-75 vs. ≤30 years: OR=1.640, 95%CI (1.021, 2.634); >75 vs. ≤30 years: OR=2.690, 95%CI (1.062, 6.814)], and pulmonary nodules detected during physical examinations [OR=1.286, 95%CI (1.064, 1.554)] were high-risk factors for malignancy, with statistical significance (P<0.05). Conclusion In the integrated management of pulmonary nodules, it is crucial not to overlook females or older patients, as they may be more significant influencing factors than smoking; furthermore, lung examinations are effective means of early detection of malignant lung tumors and are worth promoting and popularizing.
Objective To investigate the smoking status and factors influencing tobacco dependence among inpatients with respiratory diseases, and analyze the relationship of salivary and plasma nicotine metabolic ratio (NMR) with tobacco dependence and withdrawal symptoms. Methods A cross-sectional study was conducted on eligible patients admitted to the Department of Respiratory and Critical Care Medicine, West China Hospital of Sichuan University, between October 2023 and October 2024. Basic information of enrolled patients was collected and smoking questionnaires were administered. The participants were categorized into current smokers or former smokers based on smoking status. The current smokers were classified into no dependence, mild dependence, moderate dependence, and severe dependence by ICD-10, Chinese guidelines, and FTND. Group differences were analyzed with ANOVA and chi-square test. Tobacco dependence risk factors were identified by univariate/multivariate logistic regression. The smokers were stratified into slow and normal metabolizers based on NMR to analyze its correlation with tobacco dependence and withdrawal symptoms. Results Among 602 enrolled patients, 20.4% initiated smoking before age 18 years, with a mean smoking history of 46.2 pack-years. Family members smoked in 49.3% and friends smoked in 89.5% of cases; primary smoking motivations were conformity, curiosity, and boredom relief. Tobacco dependents had significantly higher rates of family member smoking (P=0.005) and withdrawal symptoms (P<0.001). Logistic regression identified lower education level, absence of pulmonary infection, parental smoking, and higher daily cigarette consumption as significant risk factors for tobacco dependence. NMR was positively correlated with nicotine dependence severity (saliva: rs=0.303, P=0.013; plasma: rs=0.297, P=0.045). Normal metabolizers had a significantly higher prevalence of nicotine dependence than slow metabolizers (saliva: 56.3% vs. 33.3%, P=0.014; plasma: 58.8% vs. 25.0%, P=0.044). Withdrawal symptoms were positively correlated with NMR (rs=0.244, P=0.048), with a higher incidence in normal metabolizers (81.3% vs. 58.8%, P=0.048). Conclusions Lower education level, absence of pulmonary infection, parental smoking, and higher daily cigarette consumption are major risk factors for tobacco dependence. Normal nicotine metabolizers are more likely to exhibit higher levels of tobacco dependence and withdrawal symptoms than slow metabolizers.
Objective To develop and validate a nomogram for predicting the risk of weaning failure in elderly patients with severe pneumonia undergoing mechanical ventilation. Methods A retrospective analysis was conducted on the clinical data of 330 elderly patients with severe pneumonia undergoing mechanical ventilation who were hospitalized in our hospital from July 2021 to July 2023. According to their weaning outcomes, they were divided into a successful group (n=213 ) and a failure group (n=117). Univariate analysis and multivariate non-conditional logistic regression analysis were used to explore the factors influencing the weaning failure of mechanical ventilation in elderly patients with severe pneumonia. Results Univariate analysis showed that there were significant differences in age, smoking status, chronic obstructive pulmonary disease, ventilation time, albumin, D-dimer, and oxygenation index levels between the two groups (all P<0.05). Multivariate logistic regression analysis revealed that age ≥65 years, smoking, presence of chronic obstructive pulmonary disease, ventilation time ≥7 days, D-dimer ≥2 000 μg/L, and reduced oxygenation index were risk factors for weaning failure in the elderly patients with severe pneumonia. The nomogram model constructed based on these factors had an area under ROC curve of 0.970 (95%CI 0.952 - 0.989), and the calibration curve demonstrated good agreement between predicted and observed values. Conclusions Age, smoking status, chronic obstructive pulmonary disease, ventilation time, D-dimer, and oxygenation index are influencing factors for weaning failure in elderly patients with severe pneumonia receiving mechanical ventilation. The nomogram model constructed based on these factors exhibits good discrimination and accuracy.
ObjectiveTo investigate the short-term quality of life in patients after single-direction video-assisted thoracic surgery (VATS) for lung cancer, and explore the related influencing factors. MethodsPatients who underwent single-direction VATS for lung cancer in the Department of Thoracic Surgery, West China Hospital, Sichuan University from July 2020 to August 2021 were continuously selected. The QLQ-C30 and QLQ-LC13 were used to evaluate the quality of life of the patients after the surgery, and the influencing factors were analyzed. ResultsA total of 193 patients were collected. There were 73 males aged 59.44±11.40 years, and 120 females aged 53.73±11.15 years. The QLQ-C30 score of the patients after single-direction VATS for lung cancer was 69.09±20.21 points. Univariate analysis and Pearson correlation analysis showed that age, occupation, anesthesia time, postoperative complications, postoperative antibiotic use time, postoperative hospital stay, insomnia, economic stress, hemoptysis, chest pain, dysphagia, arm or shoulder pain were associated with the quality of life (P≤0.05). The results of multiple regression analysis showed that anesthesia time, economic pressure, insomnia and chest pain had a significant impact on the overall quality of life 30 days after the surgery (P≤0.05). ConclusionThe anesthesia time, economic pressure, insomnia and chest pain are independent influencing factors for the quality of life after the VATS lung cancer surgery.
Objective To understand the incidence of frailty in maintenance hemodialysis (MHD) patients, and to explore the correlation and influencing factors of frailty in MHD patients, so as to provide some basis for the intervention of frailty in MHD patients. Methods Patients who underwent MHD in the Department of Nephrology of West China Hospital of Sichuan University from January to March 2021 were selected. Frail scale and Pittsburgh Sleep Quality Index (PSQI) were used for evaluation, and the influencing factors of frail in patients with MHD and its correlation with frail were analyzed. Results A total of 141 patients with MHD were included, including 57 cases without frailty (40.43%), 71 cases in early frailty (50.35%), and 13 cases in frailty (9.22%). 54 cases (38.30%) had very good sleep quality, 56 cases (39.72%) had good sleep quality, 24 cases (17.02%) had average sleep quality, and 7 cases (4.96%) had very poor sleep quality. The frailty of MHD patients was positively correlated with age (rs=0.265, P=0.002), PSQI (rs=0.235, P=0.005) and magnesium (rs=0.280, P=0.001). Logistic regression analysis showed that the influencing factors of MHD patients’ frailty were gender [odds ratio (OR) =4.321, 95%confidence interval (CI) (1.525, 12.243), P=0.006], PSQI [OR=1.110, 95%CI (1.009, 1.222), P=0.032], magnesium [OR=122.072, 95%CI (4.752, 3 135.528), P=0.004], hypertension [OR=0.112, 95%CI (0.023, 0.545), P=0.007] and other diseases [OR=0.102, 95%CI (0.019, 0.552), P=0.008]. Conclusions The incidence of frailty in MHD patients is high. Gender, PSQI, magnesium, hypertension and other diseases are the influencing factors of frailty in MHD patients, and there is a correlation between frailty and sleep. It is suggested that renal medical staff should pay more attention to the assessment of MHD frailty and sleep, and carry out multi-disciplinary personalized intervention to improve the quality of life of MHD patients.
Objective To explore the current situation and influencing factors of self-regulatory fatigue in maintenance hemodialysis (MHD) patients, so as to provide good dialysis treatment for MHD patients, reduce their level of self-regulated fatigue and improve their quality of life. Methods The convenient sampling method was used to select the MHD patients in the Wenjiang Hemodialysis Center of West China Hospital of Sichuan University between April 12 and April 30, 2022. The patients were investigated by self-made basic information scale and self-regulatory fatigue scale. Results A total of 131 patients were included. The average score of self-regulatory fatigue was 53.47±6.45, cognitive dimension was 20.21±2.39, emotional dimension was 20.85±2.85, behavioral dimension was 12.40±3.63. The results of multiple linear stepwise regression analysis showed that age, duration of dialysis and educational background could inversely predict the score of self-regulatory fatigue (P<0.05). Conclusions MHD patients have a high level of self-regulatory fatigue. Clinical nurses can make individual dialysis programs according to the actual situation of MHD patients, improve their self-regulated level and physical and mental health, and improve the quality of life of MHD patients.
Objective To investigate the status and influencing factors of psychosis-related post-traumatic stress disorder (PR-PTSD) in hospitalized patients with schizophrenia. Methods A questionnaire survey was conducted among the hospitalized patients with schizophrenia in three grade Ⅱ or above psychiatric hospitals in Chengdu between March and July, 2022, using the convenient sampling method. Questionnaires included the General Information Questionnaire, Impact of Event Scale-revised (IES-R), Self-rating Depression Scales, Simplified Coping Style Questionnaire, and Intolerance of Uncertainty Scale. If the score showed skewed distribution, it was expressed by the median (lower quartile, upper quartile). According to IES-R score, the patients included were divided into 2 groups. The patients whose score ≥33 were divided into PR-PTSD group, and <33 were divided into non-PR-PTSD group. The general information of the two groups of patients were compared. The correlation between PR-PTSD and depression, coping style and intolerance of uncertainty of the included patients were analyzed. The factors affecting the PR-PTSD of hospitalized patients with schizophrenia were analyzed by multivariate binary logistic regression analysis. Results A total of 388 patients were included. Among them, there were 282 cases in the non-PR-PTSD group and 106 cases in the PR-PTSD group. The IES-R score was 23.00 (15.00, 33.00), the depression score was 45.00 (38.00, 53.00), the negative coping style score was 11.00 (8.00, 14.75), the positive coping style score was 20.00 (16.00, 25.00), and the intolerance of uncertainty score was 28.00 (22.25, 33.00). IES-R was positively correlated with depression (r=0.370, P<0.001), negative coping style (r=0.396, P<0.001), positive coping style (r=0.111, P=0.029) and intolerance of uncertainty (r=0.467, P<0.001). Regression analysis showed that depression [(odds ratio, OR)=1.073, 95% confidence interval (CI) (1.043, 1.105), P<0.001)], negative coping style [OR=1.121, 95%CI (1.040, 1.208), P=0.003], intolerance of uncertainty [OR=1.081, 95%CI (1.045, 1.118), P<0.001] were the influencing factors of PR-PTSD in hospitalized patients with schizophrenia. Conclusions The prevalence of PR-PTSD in hospitalized patients with schizophrenia is high. Depression, negative coping style and intolerance of uncertainty are the risk factors for PR-PTSD in hospitalized schizophrenia patients.
