Background: The causality of the relationship between bronchiectasis and chronic obstructive pulmonary disease (COPD) remains unclear. This study aims to investigate the potential causal relationship between them, with a specific focus on the role of airway inflammation, infections, smoking as the mediators in the development of COPD. Methods: We conducted a two-sample Mendelian randomization (MR) analysis to assess: (1) the causal impact of bronchiectasis on COPD, sex, smoking status, infections, eosinophil and neutrophil counts, as well as the causal impact of COPD on bronchiectasis; (2) the causal effect of smoking status, infections and neutrophil counts on COPD; and (3) the extent to which the smoking status, infections and neutrophil counts might mediate any influence of bronchiectasis on the development of COPD. Results: COPD was associated with a higher risk of bronchiectasis (OR 1.28 [95% CI 1.05, 1.56]). Bronchiectasis was associated with a higher risk of COPD (OR 1.08 [95% CI 1.04, 1.13]), higher levels of neutrophil (OR 1.01 [95% CI 1.00, 1.01]), higher risk of respiratory infections (OR 1.04 [95% CI 1.02, 1.06]) and lower risk of smoking. The causal associations of higher neutrophil cells, respiratory infections and smoking with higher COPD risk remained after performing sensitivity analyses that considered different models of horizontal pleiotropy, with OR 1.17, 1.69 and 95.13, respectively. The bronchiectasis-COPD effect was 0.99, 0.85 and 122.79 with genetic adjustment for neutrophils, respiratory infections and smoking. Conclusion: COPD and bronchiectasis are mutually causal. And increased neutrophil cell count and respiratory infections appears to mediate much of the effect of bronchiectasis on COPD.
背景：支气管扩张与慢性阻塞性肺疾病（COPD）之间的因果关系仍不清楚。本研究旨在探讨二者之间的潜在因果关系，特别关注气道炎症、感染和吸烟在慢性阻塞性肺病发病中的媒介作用。研究方法我们进行了双样本孟德尔随机化（MR）分析，以评估(1）支气管扩张对慢性阻塞性肺病、性别、吸烟状况、感染、嗜酸性粒细胞和中性粒细胞计数的因果影响，以及慢性阻塞性肺病对支气管扩张的因果影响；（2）吸烟状况、感染和中性粒细胞计数对慢性阻塞性肺病的因果效应；以及（3）吸烟状况、感染和中性粒细胞计数可能在多大程度上介导支气管扩张对慢性阻塞性肺病发展的影响。研究结果慢性阻塞性肺病与较高的支气管扩张风险相关（OR 1.28 [95% CI 1.05, 1.56]）。支气管扩张与较高的慢性阻塞性肺病风险（OR 1.08 [95% CI 1.04, 1.13]）、较高的中性粒细胞水平（OR 1.01 [95% CI 1.00, 1.01]）、较高的呼吸道感染风险（OR 1.04 [95% CI 1.02, 1.06]）和较低的吸烟风险相关。在进行敏感性分析并考虑不同的水平褶积模型后，中性粒细胞增多、呼吸道感染和吸烟与慢性阻塞性肺病风险升高之间的因果关系依然存在，OR 值分别为 1.17、1.69 和 95.13。对中性粒细胞、呼吸道感染和吸烟进行遗传调整后，支气管扩张与慢性阻塞性肺病的效应分别为 0.99、0.85 和 122.79。结论慢性阻塞性肺病和支气管扩张互为因果。中性粒细胞计数和呼吸道感染的增加似乎在很大程度上介导了支气管扩张对慢性阻塞性肺病的影响。

Background: The ILD-GAP scoring system is known to be useful in predicting prognosis in patients with interstitial lung disease (ILD). An elevated monocyte count was associated with increased risks of IPF poor prognosis. We examined whether the ILD-GAP scoring system combined with the monocyte ratio (ILD-GAPM) is superior to the conventional ILD-GAP model in predicting ILD prognosis. Methods: In patients with ILD treated between April 2013 and April 2017, we were retrospectively assessed the relationships between baseline clinical parameters, including age, sex, Charlson Comorbidity Index score (CCIS), ILD diagnosis, blood biomarkers, pulmonary function test results, and disease outcomes. In ILD patients were included idiopathic pulmonary fibrosis (IPF), idiopathic nonspecific interstitial pneumonia (iNSIP), collagen vascular disease-related interstitial pneumonia (CVD-IP), chronic hypersensitivity pneumonitis (CHP), and unclassifiable ILD (UC-ILD). We also assessed the ability to predict prognosis was compared between the ILD-GAP and ILD-GAPM models. Results: A total of 179 patients (mean age, 73 years) were assessed. All of them were taken pulmonary function test, including percentage predicted diffusion capacity for carbon monoxide. ILD patients included 56 IPF cases, 112 iNSIP and CVD-IP cases, 6 CHP cases and 5 UC-ILD cases. ILD-GAPM provided a greater area under the receiver-operating characteristic curve (0.747) than ILD-GAP (0.710) for predicting 3-year ILD-related events. Furthermore, the log-rank test showed that the Kaplan-Meier curves in ILD-GAPM were significantly different by stage (P = 0.015), but not by stage in ILD-GAP (P = 0.074). Conclusions: The ILD-GAPM model may be a more accurate predictor of prognosis for ILD patients than the ILD-GAP model.

Background: Several studies have indicated that intrapleural infusion of bevacizumab is an effective treatment for non-small cell lung cancer (NSCLC) with malignant pleural effusion (MPE). However, the impact of bevacizumab administered through an indwelling pleural catheter (IPC) on the prognosis of these patients is unknown. Methods: Consecutive advanced NSCLC patients with symptomatic MPE receiving an IPC alone or bevacizumab through an IPC were identified in a tertiary hospital. The patient characteristics and clinical outcomes were collected. Results: A total of 149 patients were included, and the median age was 60.3 years. Males and nonsmokers accounted for 48.3% and 65.8%, respectively. A total of 69.8% (104/149) of patients harbored actionable mutations, including 92 EGFR-activating mutations, 11 ALK fusions, and 1 ROS1 fusion. A total of 81.9% (122/149) of patients received IPC alone, and 18.1% (27/149) received bevacizumab through an IPC. The incidence of spontaneous pleurodesis during the first 6 months was greater in the bevacizumab-treated group than in the IPC-treated group in the subgroup with actionable mutations (64.3% vs. 46.9%, P = 0.28). The median overall survival (OS) in patients with actionable mutations treated with bevacizumab through an IPC was 42.2 months, which was significantly longer than the 26.7 months in patients who received an IPC alone (P = 0.045). However, the median OS did not differ between the two arms in the subgroup without actionable mutations (10.8 vs. 41.0 months, P = 0.24). No significant difference between the bevacizumab through an IPC group and the IPC group was detected in the number of participants who had adverse events, either in patients with actionable mutations (14.3% vs. 8.4%; P = 0.42) or in patients without actionable mutations (16.7% vs. 12.8%; P = 1.00).
背景：多项研究表明，胸膜腔内输注贝伐珠单抗是治疗伴有恶性胸腔积液（MPE）的非小细胞肺癌（NSCLC）的有效方法。然而，通过留置胸膜导管（IPC）输注贝伐单抗对这些患者预后的影响尚不清楚。研究方法在一家三甲医院中连续发现了接受单独IPC或通过IPC接受贝伐珠单抗治疗的无症状MPE晚期NSCLC患者。收集患者特征和临床结果。结果：共纳入 149 名患者，中位年龄为 60.3 岁。男性和非吸烟者分别占 48.3% 和 65.8%。共有69.8%（104/149）的患者携带可操作突变，包括92个表皮生长因子受体激活突变、11个ALK融合和1个ROS1融合。81.9%的患者（122/149）仅接受了IPC治疗，18.1%的患者（27/149）通过IPC接受了贝伐单抗治疗。在有可操作突变的亚组中，贝伐珠单抗治疗组在前6个月的自发性胸膜剥脱发生率高于IPC治疗组（64.3% vs. 46.9%，P = 0.28）。通过IPC接受贝伐珠单抗治疗的可作用突变患者的中位总生存期（OS）为42.2个月，明显长于单独接受IPC治疗的患者的26.7个月（P = 0.045）。然而，在没有可操作突变的亚组中，两种治疗方案的中位OS没有差异（10.8个月 vs. 41.0个月，P = 0.24）。在发生不良事件的参与者人数方面，通过IPC治疗贝伐单抗组与IPC组之间没有发现明显差异，无论是在有可作用突变的患者中（14.3% vs. 8.4%; P = 0.42），还是在没有可作用突变的患者中（16.7% vs. 12.8%; P = 1.00）。

Background: Although multidrug-resistant bacteria (MDR) are common in patients undergoing prolonged weaning, there is little data on their impact on weaning and patient outcomes. Methods: This is a retrospective analysis of consecutive patients who underwent prolonged weaning and were at a university weaning centre from January 2018 to December 2020. The influence of MDR colonisation and infection on weaning success (category 3a and 3b), successful prolonged weaning from invasive mechanical ventilation (IMV) with or without the need for non-invasive ventilation (NIV) compared with category 3c (weaning failure 3cI or death 3cII) was investigated. The pathogen groups considered were: multidrug-resistant gram-negative bacteria (MDRGN), methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus spp. (VRE). Results: A total of 206 patients were studied, of whom 91 (44.2%) showed evidence of MDR bacteria (32% VRE, 1.5% MRSA and 16% MDRGN), with 25 patients also meeting the criteria for MDR infection. 70.9% of the 206 patients were successfully weaned from IMV, 8.7% died. In 72.2% of cases, nosocomial pneumonia and other infections were the main cause of death. Patients with evidence of MDR (infection and colonisation) had a higher incidence of weaning failure than those without evidence of MDR (48% vs. 34.8% vs. 21.7%). In multivariate analyses, MDR infection (OR 4.9, p = 0.004) was an independent risk factor for weaning failure, along with male sex (OR 2.3, p = 0.025), Charlson Comorbidity Index (OR 1.2, p = 0.027), pH (OR 2.7, p < 0.001) and duration of IMV before admission (OR 1.01, p < 0.001). In addition, MDR infection was the only independent risk factor for death (category 3cII), (OR 6.66, p = 0.007). Conclusion: Patients with MDR infection are significantly more likely to die during the weaning process. There is an urgent need to develop non-antibiotic approaches for the prevention and treatment of MDR infections as well as clinical research on antibiotic stewardship in prolonged weaning as well as in ICUs.

Bronchoscopy is an invasive procedure, and patient coughing during examination has been reported to cause patient distress. This study aimed to clarify the relationship between cough severity and diagnostic yield of endobronchial ultrasonography with guide sheath transbronchial biopsy (EBUS-GS-TBB). Data of patients who underwent bronchoscopy at Kyorin University Hospital between April 2019 and March 2022 were retrospectively evaluated. Bronchoscopists assessed the cough severity upon completion of the procedure using a four-point cough scale. Cough severity was included as a predictive factor along with those reportedly involved in bronchoscopic diagnosis, and their impact on diagnostic yield was evaluated. Predictors of cough severity were also examined. A total of 275 patients were enrolled in this study. In the multivariate analysis, the diagnostic group (n = 213) had significantly more ‹within› radial endobronchial ultrasound findings (odds ratio [OR] 5.900, p < 0.001), a lower cough score (cough score per point; OR 0.455, p < 0.001), and fewer bronchial generations to target lesion(s) (OR 0.686, p < 0.001) than the non-diagnostic group (n = 62). The predictive factors for severe cough include the absence of virtual bronchoscopic navigation (VBN) and prolonged examination time. Decreased cough severity was a positive predictive factor for successful EBUS-GS-TBB, which may be controlled using VBN and awareness of the procedural duration.

Hintergrund: Bei Patienten mit nosokomialer bakterieller Pneumonie ist die Mortalität am höchsten bei denjenigen, die so weit dekompensieren, dass eine mechanische Beatmung (vHABP) nötig wird, gefolgt von denen mit beatmungsassoziierter Pneumonie (VABP) und nicht beatmungsassoziierter, im Krankenhaus erworbener Pneumonie (nvHABP). Die Ziele dieser Studie waren die Identifizierung von Risikofaktoren, die mit der Entwicklung und der Mortalität von vHABP assoziiert sind, und die Bewertung der Antibiotikabehandlung. Methoden: Eine multizentrische retrospektive Kohortenstudie wurde bei erwachsenen hospitalisierten Patienten mit nosokomialer Pneumonie zwischen 2014 und 2019 durchgeführt. Die Gruppen wurden nach vHABP, nvHABP und VABP stratifiziert und hinsichtlich demografischer Daten, klinischer Merkmale, Behandlung und Ergebnissen verglichen. Mithilfe von maschinellem Lernen wurden multivariate Modelle erstellt, um Risikofaktoren für die Progression zur vHABP und die Mortalität durch Pneumonie für jede Kohorte zu identifizieren. Ergebnisse: 457 Patienten (32% nvHABP, 37% vHABP und 31% VABP) wurden untersucht. Die vHABP- und die nvHABP-Gruppe waren ähnlich alt (medianes Alter 66,4 Jahre), 77% wiesen mehrere Komorbiditäten auf, aber mehr vHABP-Patienten hatten eine Lebererkrankung (18,2% vs. 7,7%; p = 0,05) und eine Alkoholkonsumstörung (27% vs. 7,1%; p < 0,001) und waren in den vorausgehenden 30 Tagen im Krankenhaus gewesen (30,4% vs. 19,5%; p = 0,02). 70% der vHABP-Patienten benötigten am Tag der Diagnose eine sofortige Beatmung. Die Mortalität war in der vHABP-Gruppe am höchsten, gefolgt von der VABP- und der nvHABP-Gruppe (44,6% vs. 36% vs. 14,3%; p < 0,0001). Fast alle (96%) vHABP-Patienten hatten positive Kulturen, wobei Gram-negative Erreger 58,8% ausmachten und 33,0% resistent gegen β-Laktame mit breitem Wirkungsspektrum (ESBL), Ceftriaxon (17,5%), Fluorchinolone (20,6%) und Carbapeneme (12,4%) waren. Bis zur Hälfte der vHABP-Patienten mit ESBL-Enterobacteriaceae oder Pseudomonas aeruginosa erhielten keine wirksame empirische Therapie. Bei Patienten, bei denen eine wirksame Therapie erst nach dem Tag der Pneumoniediagnose begonnen wurde, war die Mortalität um mehr als 50% erhöht. Risikofaktoren, die mit der Entwicklung einer vHABP assoziiert waren, waren Alkoholkonsumstörung, APACHE-II-Score, eine Vasopressortherapie vor der Infektion und eine positive Kultur für ESBL-Enterobacteriales, während eine Krankenhausaufnahme in den letzten 30 Tagen, eine aktive maligne Erkrankung, die Isolierung von Ceftriaxon-resistenten Erregern oder P. aeruginosa und eine Vasopressortherapie Risikofaktoren für eine vHABP-assoziierte Mortalität waren.

Die Ziele dieser Studie waren die Identifizierung von Risikofaktoren, die mit der Entwicklung und der Mortalität von vHABP assoziiert sind, und die Bewertung der Antibiotikabehandlung. Methoden: Eine multizentrische retrospektive Kohortenstudie wurde bei erwachsenen hospitalisierten Patienten mit nosokomialer Pneumonie zwischen 2014 und 2019 durchgeführt. Die Gruppen wurden nach vHABP, nvHABP und VABP stratifiziert und hinsichtlich demografischer Daten, klinischer Merkmale, Behandlung und Ergebnissen verglichen. Mithilfe von maschinellem Lernen wurden multivariate Modelle erstellt, um Risikofaktoren für die Progression zur vHABP und die Mortalität durch Pneumonie für jede Kohorte zu identifizieren. Ergebnisse: 457 Patienten (32% nvHABP, 37% vHABP und 31% VABP) wurden untersucht. Die vHABP- und die nvHABP-Gruppe waren ähnlich alt (medianes Alter 66,4 Jahre), 77% wiesen mehrere Komorbiditäten auf, aber mehr vHABP-Patienten hatten eine Lebererkrankung (18,2% vs. 7,7%; p = 0,05) und eine Alkoholkonsumstörung (27% vs. 7,1%; p < 0,001) und waren in den vorausgehenden 30 Tagen im Krankenhaus gewesen (30,4% vs. 19,5%; p = 0,02). 70% der vHABP-Patienten benötigten am Tag der Diagnose eine sofortige Beatmung. Die Mortalität war in der vHABP-Gruppe am höchsten, gefolgt von der VABP- und der nvHABP-Gruppe (44,6% vs. 36% vs. 14,3%; p < 0,0001). Fast alle (96%) vHABP-Patienten hatten positive Kulturen, wobei Gram-negative Erreger 58,8% ausmachten und 33,0% resistent gegen β-Laktame mit breitem Wirkungsspektrum (ESBL), Ceftriaxon (17,5%), Fluorchinolone (20,6%) und Carbapeneme (12,4%) waren. Bis zur Hälfte der vHABP-Patienten mit ESBL-Enterobacteriaceae oder Pseudomonas aeruginosa erhielten keine wirksame empirische Therapie.

Background: Clinical guidelines recommend a preoperative forced expiratory volume in one second (FEV1) of > 2 L as an indication for left or right pneumonectomy. This study compares the safety and long-term prognosis of pneumonectomy for destroyed lung (DL) patients with FEV1 ≤ 2 L or > 2 L. Methods: A total of 123 DL patients who underwent pneumonectomy between November 2002 and February 2023 at the Department of Thoracic Surgery, Beijing Chest Hospital were included. Patients were sorted into two groups: the FEV1 > 2 L group (n = 30) or the FEV1 ≤ 2 L group (n = 96). Clinical characteristics and rates of mortality, complications within 30 days after surgery, long-term mortality, occurrence of residual lung infection/tuberculosis (TB), bronchopleural fistula/empyema, readmission by last follow-up visit, and modified Medical Research Council (mMRC) dyspnea scores were compared between groups. Results: A total of 96.7% (119/123) of patients were successfully discharged, with 75.6% (93/123) in the FEV1 ≤ 2 L group. As compared to the FEV1 > 2 L group, the FEV1 ≤ 2 L group exhibited significantly lower proportions of males, patients with smoking histories, patients with lung cavities as revealed by chest imaging findings, and patients with lower forced vital capacity as a percentage of predicted values (FVC%pred) (P values of 0.001, 0.027, and 0.023, 0.003, respectively). No significant intergroup differences were observed in rates of mortality within 30 days after surgery, incidence of postoperative complications, long-term mortality, occurrence of residual lung infection/TB, bronchopleural fistula/empyema, mMRC ≥ 1 at the last follow-up visit, and postoperative readmission (P > 0.05).
背景：临床指南建议将术前一秒用力呼气容积（FEV1）大于 2 L 作为左肺或右肺切除术的指征。本研究比较了 FEV1 ≤ 2 L 或 > 2 L 的毁损肺（DL）患者接受肺切除术的安全性和长期预后：共纳入 2002 年 11 月至 2023 年 2 月期间在北京胸科医院胸外科接受肺切除术的 123 例 DL 患者。患者被分为两组：FEV1 > 2 L 组（30 人）或 FEV1 ≤ 2 L 组（96 人）。比较两组患者的临床特征和死亡率、术后 30 天内的并发症、长期死亡率、肺部感染/肺结核（TB）残留、支气管胸膜瘘/水肿的发生率、最后一次随访时的再入院率以及改良医学研究委员会（mMRC）呼吸困难评分。结果显示共有96.7%（119/123）的患者成功出院，其中FEV1≤2 L组为75.6%（93/123）。与 FEV1 > 2 L 组相比，FEV1 ≤ 2 L 组的男性比例、有吸烟史的患者比例、胸部影像学检查结果显示有肺空洞的患者比例以及用力肺活量占预测值百分比（FVC%pred）较低的患者比例均明显较低（P 值分别为 0.001、0.027 和 0.023、0.003）。在术后 30 天内死亡率、术后并发症发生率、长期死亡率、肺部感染/结核残留、支气管胸膜瘘/水肿发生率、最后一次随访时 mMRC ≥ 1 以及术后再入院率方面，未观察到明显的组间差异（P > 0.05）。
