Introduction

Noninvasive evaluation of airway conditions is considered useful in the management of COPD, although assessing airway remodeling remains difficult in routine clinical practice. The impulse oscillometry system used in this study allows separate analysis of inspiratory and expiratory phases, offering detailed insights into airway function. This study examined the effects of inhaled corticosteroids (ICSs) on airway remodeling and assessed the utility of this system in COPD management.

Methods

Stable COPD patients on LAMA/LABA for over a year were assessed by spirometry and impulse oscillometry at baseline and after 48 weeks of ICS/LAMA/LABA therapy. Symptoms, imaging, and blood tests were also evaluated.

Results

Among 52 patients (mean baseline %FEV1/predicted: 56.9% ± 22.1%), all had one to two moderate exacerbations in the past year despite LAMA/LABA therapy. Significant correlations were observed between spirometry and MostGraph (e.g., baseline FEV1 vs. R5: r = −0.54). Although spirometry showed no significant changes, Fres improved significantly (−2.11 ± 0.35, p < 0.0001), with reductions in both expiratory and inspiratory phases.

Conclusions

Fres measured by MostGraph significantly improved after ICS addition, whereas no significant changes were observed in spirometry or resistance parameters. Fres also showed significant correlations with FEV1, suggesting that it may capture airway changes not detected by spirometry. These findings support further investigation into its role as a noninvasive marker in COPD.

尽管在常规临床实践中评估气道重塑仍然很困难，但无创气道状况评估被认为对COPD的治疗有用。本研究中使用的脉冲振荡测量系统可以对吸气和呼气相进行单独分析，从而提供对气道功能的详细了解。本研究探讨了吸入皮质类固醇（ICSs）对气道重塑的影响，并评估了该系统在COPD治疗中的效用。方法采用ICS/LAMA/LABA治疗1年以上的稳定期COPD患者，分别在基线和治疗48周后进行肺活量测定和脉冲振荡测定。还对症状、影像学和血液检查进行了评估。结果在52例患者中（平均基线%FEV1/预测：56.9%±22.1%），尽管进行了LAMA/LABA治疗，但在过去的一年中，所有患者均有1至2次中度加重。肺活量测定和MostGraph之间观察到显著相关性（例如，基线FEV1与R5: r = - 0.54）。虽然肺活量测定没有明显变化，但Fres明显改善（- 2.11±0.35,p < 0.0001），呼气期和吸气期均减少。结论加入ICS后，MostGraph测量Fres明显改善，肺活量和阻力参数无明显变化。Fres也显示出与FEV1的显著相关性，表明它可能捕捉到肺活量测定法未检测到的气道变化。这些发现支持进一步研究其作为COPD非侵入性标志物的作用。UMIN-CTR临床试验：UMIN000040764 （https://upload.umin.ac.jp/cgi-open-bin/ctr_e/ctr_view.cgi?recptno=R000042394）

Background

Elderly patients are prone to secretion retention and exacerbated lung infections due to weakened respiratory muscle strength and reduced ability to cough and expectorate. Airway clearance techniques (ACTs) can help to clear airway secretions, but objective bedside assessment of secretion clearance efficacy is lacking. Electrical impedance tomography (EIT) can dynamically monitor lung ventilation and provide a basis for clinical decision-making.

Methods

This study was a prospective randomized controlled trial that included 50 elderly patients with severe pneumonia, who were randomized into EIT and non-EIT groups. The EIT group received personalized ACTs guided by real-time EIT imaging with dynamic adjustment of posture, percussion intensity, and active circulatory breathing technique (ACBT) frequency, whereas the non-EIT group received fixed-schedule ACTs (postural drainage every 2 h + percussion/vibration twice daily) without EIT feedback. The main observation indices included Clinical Pulmonary Infection Score (CPIS), respiratory mechanics indices, blood gas analysis indices, and extubation success rate.

Results

The EIT group showed significantly lower CPIS scores (p = 0.0137 on Day 7), higher dynamic compliance (p = 0.0193), lower airway resistance (p = 0.0039), lower peak airway pressure (p = 0.0288), and higher oxygenation index (p = 0.0143 on Day 5 and p = 0.0005 on Day 7) than the non-EIT group. The extubation success rate was significantly higher in the EIT group (88% vs. 56%, p = 0.0255). Additionally, the EIT group demonstrated progressive improvements in ventilation in specific regions (D7 vs. D1: p = 0.0004 for region of interest [ROI]3; p = 0.0059 for ROI4) and a significant decrease in the global inhomogeneity index at D7 (D7 vs. D1: p = 0.0025).

Conclusion

EIT-guided ACT is safe and enhances treatment efficacy by significantly improving respiratory function and extubation success rate in elderly patients with severe pneumonia.

背景老年患者由于呼吸肌力减弱，咳嗽和咳痰能力下降，容易出现分泌物潴留，加重肺部感染。气道清除技术（act）有助于清除气道分泌物，但缺乏对分泌物清除效果的客观床边评估。电阻抗断层扫描（EIT）可以动态监测肺通气情况，为临床决策提供依据。方法采用前瞻性随机对照试验，将50例老年重症肺炎患者随机分为EIT组和非EIT组。EIT组接受实时EIT成像指导下的个性化act，动态调整体位、打击强度和主动循环呼吸技术（ACBT）频率，而非EIT组接受固定时间act（每2小时体位引流+每天两次打击/振动），无EIT反馈。主要观察指标包括临床肺部感染评分（CPIS）、呼吸力学指标、血气分析指标、拔管成功率。结果EIT组CPIS评分（第7天p = 0.0137）、动态顺应性（p = 0.0193）、气道阻力（p = 0.0039）、气道压力峰（p = 0.0288）、氧合指数（第5天p = 0.0143、第7天p = 0.0005）显著低于非EIT组。EIT组拔管成功率明显高于对照组（88%比56%，p = 0.0255）。此外，EIT组在特定区域的通气表现出进行性改善(D7 vs. D1：感兴趣区域[ROI]3 p = 0.0004；ROI4的p = 0.0059)， D7时全球不均匀性指数显著下降（D7 vs. D1: p = 0.0025）。结论eit引导ACT治疗老年重症肺炎患者呼吸功能和拔管成功率明显提高，安全可靠，可提高治疗效果。

Introduction

The cystatin family is particularly relevant in lung cancer research due to its links to inflammation, protease balance, and tumor progression. Although population-based studies have documented associations between cystatin and lung cancer, causal relationships remain undetermined.

Methods

Based on genomic statistics of seven different cystatins and three subtypes of lung cancer, we conducted a two-sample Mendelian randomization (MR) study. The inverse-variance weighted (IVW) method was the main approach for causality estimation. The weighted median, simple mode, weighted mode, and MR-Egger regression methods were further employed to validate the main findings. In the sensitivity analysis, horizontal pleiotropy was assessed by MR-Egger regression and Cochran’s Q test. MR-PRESSO and Radial MR methods were used to identify heterogeneity and remove outliers.

Results

Genetically predicted Cystatin 8 was causally associated with squamous cell lung carcinoma (OR = 1.062, 95% CI: 1.004–1.124, p = 0.035). No causal relationships were found for genetically predicted cystatin 8, -B, -D, -F, or -M with squamous cell lung carcinoma, lung adenocarcinoma, and NSCLC. However, outliers were identified between Cystatin D, -M, and -F using MR-PRESSO and Radial MR. After the removal of outliers, the association between Cystatin D and lung adenocarcinoma turned significant (OR = 1.178, 95% CI: 1.023–1.358, p = 0.023). Sensitivity analyses confirmed the robustness of main results after outliers removal.

Conclusion

Genetically predicted Cystatin 8 was causally associated with squamous cell lung carcinoma. Future population-based studies are required to substantiate these results.

胱氨酸抑素家族在肺癌研究中特别重要，因为它与炎症、蛋白酶平衡和肿瘤进展有关。尽管以人群为基础的研究证实了胱抑素与肺癌之间的关联，但因果关系仍不确定。方法基于7种不同胱抑素和3种肺癌亚型的基因组统计数据，进行双样本孟德尔随机化（MR）研究。反方差加权法（IVW）是因果关系估计的主要方法。进一步采用加权中位数、简单模式、加权模式和MR-Egger回归方法对主要发现进行验证。在敏感性分析中，采用MR-Egger回归和Cochran’s Q检验评估水平多效性。MR- presso和Radial MR方法用于识别异质性和去除异常值。结果基因预测Cystatin 8与鳞状细胞肺癌相关（OR = 1.062, 95% CI: 1.004 ~ 1.124, p = 0.035）。基因预测的胱抑素8、-B、-D、-F或-M与鳞状细胞肺癌、肺腺癌和非小细胞肺癌没有因果关系。然而，使用MR-PRESSO和Radial mr发现了胱抑素D、-M和-F之间的异常值。在去除异常值后，胱抑素D与肺腺癌之间的相关性变为显著性（OR = 1.178, 95% CI: 1.023-1.358, p = 0.023）。敏感性分析证实了剔除异常值后主要结果的稳健性。结论基因预测Cystatin 8与鳞状细胞肺癌相关。需要未来以人群为基础的研究来证实这些结果。

Objectives

Lung cancer metastasis constitutes a critical aspect of disease progression and patient outcomes. It is imperative to illuminate the complex landscape of lung cancer metastasis, offering a thorough evaluation of sites, rates, risk factors, and survival implications.

Methods

Studies on the prevalence of lung cancer metastasis, the risk factors, the overall survival (OS) after metastasis, or the risk factors for OS were included. Two independent reviewers used a standardized data extraction and quality assessment form. Hazard ratios and confidence intervals were calculated using random-effects or fixed-effects models.

Results

This systematic meta-analysis included 115 clinical trials. Prevalent metastatic sites in non-small cell lung carcinoma (NSCLC) encompassed brain (29%), bone (25%), adrenal gland (15%), liver (13%), and skin (3%). However, small cell lung carcinoma (SCLC) primarily metastasized to liver (33%), brain (30%), bone (27%), adrenal gland (10%), and pericardium (3%). The risk factors for brain metastases in NSCLC included lung adenocarcinoma, EGFR mutations, and prophylactic cranial irradiation (PCI); in SCLC brain metastasis, age and PCI were influential. The median OS after brain metastasis in NSCLC and SCLC was 21.3 and 10.5 months, respectively, while liver or bone metastases were notably linked to poorer survival. The factors influencing OS in NSCLC brain metastasis included age, EGFR mutations, and stereotactic radiosurgery. For SCLC brain metastasis, OS was notably impacted by gender, smoking status, the number of brain metastases, and radiotherapy.

Conclusion

This study provided insights into lung cancer metastasis. The results revealed the metastatic rates, risk factors, and OS to assist clinical decision-making.

Introduction

Idiopathic pulmonary fibrosis (IPF) leads to irreversible scarring of lung tissue, resulting in deteriorating respiratory function, particularly in older adults. We aimed to explore the causative link between hypothyroidism and IPF, particularly focusing on immune cell phenotypes as mediating factors.

Methods

A two-sample Mendelian randomization (MR) approach was utilized to investigate the influence of hypothyroidism on IPF and the role of 731 distinct immune cell phenotypes as mediators. The mediating effects were quantified using the coefficient product method. Various sensitivity analyses, including Cochran's Q test for heterogeneity, MR–Egger for pleiotropy, and the “leave-one-out” method, were conducted to verify the robustness of single-nucleotide polymorphism–derived casual estimates. Statistical analyses were carried out using the R software (Version 4.3.1).

Results

Hypothyroidism was significantly associated with increased IPF risk (odds ratio [OR] = 1.13, 95% confidence interval [CI] = 1.06–1.21, p = 1.34 × 10⁻⁴). Of the 36 immune cell phenotypes associated with IPF, those related to the mean fluorescence intensity of B cells were the most prevalent. Mediation analysis showed that CD19 on IgD− CD27− accounted for approximately 3.68% of the effect of hypothyroidism on IPF, whereas herpesvirus entry mediator (HVEM) on T cells accounted for approximately 3.83% of this effect.

Conclusion

We identified a marked association between hypothyroidism and IPF. Specific immune cell phenotypes may partially mediate this relationship, although the observed effect sizes were modest. Further research is needed to validate these results in diverse populations and larger clinical trials.

特发性肺纤维化（IPF）导致肺组织不可逆的瘢痕形成，导致呼吸功能恶化，特别是在老年人中。我们的目的是探讨甲状腺功能减退和IPF之间的因果关系，特别关注免疫细胞表型作为中介因素。方法采用双样本孟德尔随机化（MR）方法研究甲状腺功能减退症对IPF的影响以及731种不同免疫细胞表型作为介质的作用。采用系数积法对中介效应进行量化。进行了各种敏感性分析，包括Cochran's Q检验异质性，MR-Egger检验多效性和“留一”方法，以验证单核苷酸多态性衍生的随机估计的稳健性。采用R软件（4.3.1版）进行统计分析。结果甲状腺功能减退与IPF风险增加显著相关（优势比[OR] = 1.13, 95%可信区间[CI] = 1.06-1.21, p = 1.34 × 10−4）。在与IPF相关的36种免疫细胞表型中，与B细胞平均荧光强度相关的表型最为普遍。中介分析显示，IgD - CD27 -上的CD19约占甲状腺功能低下对IPF影响的3.68%，而T细胞上的疱疹病毒进入介质（HVEM）约占这种影响的3.83%。结论甲状腺功能减退与IPF之间存在显著的相关性。特异性免疫细胞表型可能部分介导这种关系，尽管观察到的效应大小是适度的。需要进一步的研究在不同的人群和更大规模的临床试验中验证这些结果。

Background

For critically ill patients in the intensive care unit (ICU), acute respiratory failure (ARF) stands as a prominent cause of mortality. Anion gap (AG) denotes the disparity between unmeasured cations and anions. Adjusting AG for albumin levels results in the albumin corrected anion gap (ACAG), which provides a more accurate representation of the body's acid–base status. Elevated ACAG may arise from ARF-induced cellular hypoxia and metabolic acidosis. However, limited research has investigated the association between ACAG and the 28-day all-cause mortality of ARF patients in critical care.

Methods

Using the Medical Information Mart for Intensive Care (MIMIC-IV 2.2) database, a retrospective data analysis was conducted, specifically targeting critically ill patients diagnosed with ARF. Serum ACAG was collected within 24 hours of the patient's admission to the ICU. The association between ACAG levels and 28-day all-cause mortality was investigated using smooth curve fitting, a multivariate Cox proportional hazard regression model, and Kaplan–Meier survival curve analysis. Furthermore, the consistency of these relationships was assessed through interaction and subgroup analyses.

Results

The study involved the enrollment of 3888 eligible participants in total. After adjusting for confounding variables in the multivariable Cox regression analysis model, we noticed a positive linear relationship between the ACAG value and the ICU's 28-day all-cause mortality rate. When ACAG was used as a continuous variable, a 3.1% increase in 28-day all-cause mortality was associated with a 1.0-mmol/L increase in ACAG (adjusted HR = 1.037, 95% CI: 1.025–1.048, p < 0.001). In the 28-day all-cause mortality, the highest and intermediate ACAG groups (adjusted HR 1.483, 95% CI: 1.244–1.768 and adjusted HR 1.244, 95% CI: 1.062–1.457, respectively) were notably higher than the lowest ACAG group when ACAG was utilized as a tertiles categorical variable. The substantial association between ACAG and 28-day all-cause mortality in the ICU was consistently demonstrated through subgroup analysis.

Conclusions

Among ICU patients with ARF, an elevated ACAG is linked to an elevated risk of 28-day all-cause mortality. There exists a linearly positive relationship between the 28-day all-cause mortality and ACAG.

背景对于重症监护病房（ICU）的危重患者，急性呼吸衰竭（ARF）是导致死亡的主要原因。阴离子间隙（AG）表示未测阳离子和阴离子之间的差异。根据白蛋白水平调整AG会产生白蛋白校正阴离子间隙（ACAG），这能更准确地反映机体的酸碱状态。ACAG升高可能由arf诱导的细胞缺氧和代谢性酸中毒引起。然而，有限的研究调查了ACAG与危重重症ARF患者28天全因死亡率之间的关系。方法利用重症医学信息集市（MIMIC-IV 2.2）数据库，对诊断为ARF的危重患者进行回顾性数据分析。患者入ICU后24小时内采集血清ACAG。采用光滑曲线拟合、多变量Cox比例风险回归模型和Kaplan-Meier生存曲线分析，研究ACAG水平与28天全因死亡率之间的关系。此外，通过相互作用和亚组分析来评估这些关系的一致性。结果本研究共纳入3888名符合条件的受试者。在多变量Cox回归分析模型中调整混杂变量后，我们注意到ACAG值与ICU 28天全因死亡率之间存在正线性关系。当ACAG作为一个连续变量时，28天全因死亡率增加3.1%与ACAG增加1.0 mmol/L相关（校正HR = 1.037, 95% CI: 1.025-1.048, p < 0.001）。在28天全因死亡率中，当ACAG作为分类变量时，最高和中级ACAG组（校正后的HR分别为1.483,95% CI为1.244 - 1.768，校正后的HR为1.244,95% CI为1.062-1.457）显著高于最低ACAG组。通过亚组分析，ACAG与ICU 28天全因死亡率之间存在实质性关联。结论：在ARF ICU患者中，ACAG升高与28天全因死亡率升高相关。28天全因死亡率与ACAG呈线性正相关。

Interstitial lung disease (ILD) is a group of diseases involving diffuse pulmonary parenchymal lesions and alveolar inflammation and interstitial fibrosis. Telomeres are repetitive DNA sequences at the end of chromosomes to maintain structural integrity and telomerase can prevent telomere shortening. Telomerase abnormalities such as related gene mutations lead to decrease in telomerase activity and telomere shortening. It has been proven that telomere shortening and telomerase abnormalities are related to the occurrence and development of ILD. Telomere shortening occurs in different types of ILD patients and is associated with prognosis. Gene therapy targeting telomerase exhibits therapeutic potential. The paper elaborates on the progress of telomere shortening in the diagnosis, differential diagnosis, treatment, and prognosis of ILD in recent years, in order to demonstrate its potential and promises and to be helpful for clinical diagnosis and treatment.

间质性肺病（ILD）是一组涉及弥漫性肺实质病变、肺泡炎症和间质纤维化的疾病。端粒是染色体末端重复的DNA序列，用于维持结构的完整性，端粒酶可以防止端粒缩短。端粒酶异常如相关基因突变导致端粒酶活性降低和端粒缩短。已证实端粒缩短和端粒酶异常与ILD的发生发展有关。端粒缩短发生在不同类型的ILD患者中，并与预后相关。以端粒酶为靶点的基因治疗显示出治疗潜力。本文就近年来端粒缩短技术在ILD的诊断、鉴别诊断、治疗及预后等方面的研究进展作一综述，以说明端粒缩短技术的潜力和前景，以期对临床诊断和治疗有所帮助。

Background

Asthma is a chronic airway inflammatory disease that significantly affects patients' quality of life and mental health. This study aims to compare the differences between acupoint embedding auxiliary therapy and traditional auxiliary therapy in asthma control, immune response, sleep quality, and quality of life, as well as evaluate their therapeutic effects on patients with asthma.

Methods

A retrospective analysis of 300 patients with asthma was conducted, divided into acupoint catgut embedding and conventional treatment groups. Key assessments included asthma control (ACQ score), exacerbation frequency, HADS, PSQI, and SF-36 for quality of life. Immune markers (IgE, eosinophil count, IL-4, IL-5, IL-10) were measured. Univariate and multivariate logistic regression analyses and ROC curves were used to identify predictors of asthma control and sleep quality. Stratified analysis evaluated differences by asthma severity.

Results

The acupoint catgut embedding group showed significant improvements in asthma control (p < 0.001), exacerbation frequency (p < 0.05), and anxiety and depression (p = 0.0359) compared to the conventional treatment group. IgE (p = 0.00656), eosinophil count (p = 0.0214), and IL-5 (p = 0.0187) were significantly lower, while IL-10 (p = 0.0226) was higher in the acupoint group. Sleep quality (PSQI score, p = 0.0117) and deep sleep (NREM 3, p < 0.05) improved. Asthma severity (p < 0.001) and treatment method (p < 0.001) were significant predictors of outcomes, with model 2 (AUC = 0.731) outperforming model 1 (AUC = 0.649). Stratified analysis showed acupoint therapy was more effective in intermittent and mild asthma.

Conclusion

As an auxiliary treatment, acupoint embedding therapy has shown a good effect in improving the sleep quality of patients with asthma and controlling asthma symptoms, especially in patients with mild-to-moderate asthma.

哮喘是一种慢性气道炎症性疾病，严重影响患者的生活质量和心理健康。本研究旨在比较穴位埋置辅助疗法与传统辅助疗法在哮喘控制、免疫反应、睡眠质量、生活质量等方面的差异，并评价其对哮喘患者的治疗效果。方法对300例哮喘患者进行回顾性分析，分为穴位埋线组和常规治疗组。主要评估包括哮喘控制（ACQ评分）、加重频率、HADS、PSQI和SF-36的生活质量。检测免疫标志物（IgE、嗜酸性粒细胞计数、IL-4、IL-5、IL-10）。采用单因素和多因素logistic回归分析及ROC曲线确定哮喘控制和睡眠质量的预测因子。分层分析评估哮喘严重程度的差异。结果穴位埋线组在哮喘控制（p < 0.001）、发作频率（p < 0.05）、焦虑和抑郁（p = 0.0359）方面均较常规治疗组有显著改善。穴位组IgE （p = 0.00656）、嗜酸性粒细胞计数（p = 0.0214）、IL-5 （p = 0.0187）显著降低，IL-10 （p = 0.0226）显著升高。睡眠质量（PSQI评分，p = 0.0117）和深度睡眠（NREM 3, p < 0.05）均有改善。哮喘严重程度（p < 0.001）和治疗方法（p < 0.001）是预后的显著预测因素，模型2 （AUC = 0.731）优于模型1 （AUC = 0.649）。分层分析显示穴位治疗对间歇性和轻度哮喘更有效。结论穴位埋点疗法作为一种辅助治疗，对改善哮喘患者的睡眠质量，控制哮喘症状有较好的效果，尤其对轻中度哮喘患者效果更好。

Exploring the Causal Relationship Between Antidepressant Use and Lung Cancer Risk: A Mendelian Randomization Analysis 探索抗抑郁药使用与肺癌风险之间的因果关系：孟德尔随机分析

IF 1.9 4区医学 Q3 RESPIRATORY SYSTEM

Clinical Respiratory Journal

Pub Date : 2025-07-02 DOI: 10.1111/crj.70102

Purpose

The dramatic increase in antidepressant prescribing over the past decade has sparked debate about the possible contribution of antidepressants to elevated cancer risk. In this study, we investigate whether antidepressant use has a causal relationship with lung cancer risk.

Methods

Genome-wide association study (GWAS) data for antidepressant use were acquired from the FinnGen Biobank, while GWAS data for overall lung cancer and specific histological subtypes were obtained from the UK Biobank (UKBB) and IEU databases. The causal impact was evaluated using inverse variance weighting (IVW), MR-Egger regression, and weighted median (WM) approaches. Multiple sensitivity analyses were conducted to validate the findings. Results are expressed as ORs and 95% CIs.

Results

No causal relationship between antidepressant use and lung cancer risk was observed in the IVW (OR = 1.001, 95% CI = 0.999, p = 0.279), MR-Egger (OR = 1.002, 95% CI = 0.992, p = 0.700), and WM analyses (OR = 1.000, 95% CI: 0.997, p = 0.889). Similar results were found across lung cancer subtypes, including lung adenocarcinoma (LUAD) (OR = 1.197, 95% CI = 0.884–1.619, p = 0.247), lung squamous cell carcinoma (LUSC) (OR = 1.052, 95% CI = 0.822, p = 0.688), and small cell lung carcinoma (SCLC) (OR = 1.874, 95% CI = 0.737, p = 0.187). Sensitivity tests confirmed the robustness of these results.

Conclusions

This analysis indicates antidepressant use is not significantly associated with lung cancer risk.

目的：在过去十年中，抗抑郁药处方的急剧增加引发了关于抗抑郁药可能导致癌症风险升高的争论。在这项研究中，我们调查抗抑郁药的使用是否与肺癌风险有因果关系。方法从FinnGen生物银行获得抗抑郁药使用的全基因组关联研究（GWAS）数据，而从UK生物银行（UKBB）和IEU数据库获得总体肺癌和特定组织学亚型的GWAS数据。因果影响的评估采用反方差加权（IVW）、MR-Egger回归和加权中位数（WM）方法。进行多重敏感性分析以验证研究结果。结果以or和95% ci表示。结果在IVW （OR = 1.001, 95% CI = 0.999, p = 0.279）、MR-Egger （OR = 1.002, 95% CI = 0.992, p = 0.700）和WM分析（OR = 1.000, 95% CI: 0.997, p = 0.889）中均未发现抗抑郁药使用与肺癌风险之间的因果关系。在肺癌亚型中也发现了类似的结果，包括肺腺癌（LUAD）（OR = 1.197, 95% CI = 0.884-1.619, p = 0.247）、肺鳞状细胞癌（LUSC）（OR = 1.052, 95% CI = 0.822, p = 0.688）和小细胞肺癌（SCLC）（OR = 1.874, 95% CI = 0.737, p = 0.187）。敏感性试验证实了这些结果的稳健性。结论：该分析表明抗抑郁药的使用与肺癌风险无显著相关性。
