Background

Airway stenting is an established procedure for treating oncological emergencies in patients with airway disorders. In patients with airway hemorrhage, respiratory conditions may worsen during stenting. Bronchial artery embolization (BAE) is useful to prevent bleeding from the bronchus. We aimed to evaluate the efficacy and safety of airway stenting after BAE in patients with malignant airway disorders.

Methods

The medical records of all patients who underwent airway stenting following BAE at the National Hospital Organization Okayama Medical Center between 2016 and 2023 were retrospectively reviewed.

Results

Thirteen procedures (11 silicone Y stents, one hybrid stent, and one self-expandable metallic stent) were performed. The median duration from BAE to airway stenting was one day (range: 1–5 days). Nine patients experienced tumor shrinkage, and none experienced severe bleeding after BAE during the stent procedure. No other major complications were associated with the stent placement. The median survival time after stenting was 169 days (range; 24–1086). No serious complications caused by BAE, such as spinal cord infarction, were observed.

Conclusions

Airway stent placement was safely performed after BAE without severe bleeding or acute respiratory failure. BAE, followed by airway stenting, is useful.

背景:气道支架植入术是治疗气道疾病患者肿瘤急症的既定程序。气道出血患者在支架植入过程中呼吸状况可能会恶化。支气管动脉栓塞(BAE)可有效防止支气管出血。我们旨在评估恶性气道疾病患者 BAE 后气道支架植入术的有效性和安全性:方法:回顾性审查了2016年至2023年间在国立医院组织冈山医疗中心接受BAE术后气道支架植入术的所有患者的病历:结果:共进行了13例手术(11例硅胶Y型支架、1例混合型支架和1例自膨胀金属支架)。从 BAE 到气道支架植入的中位时间为一天(范围:1-5 天)。九名患者的肿瘤缩小,没有人在 BAE 支架术后出现严重出血。支架置入过程中未出现其他重大并发症。支架植入后的中位生存时间为 169 天(范围:24-1086 天)。未观察到 BAE 引起的脊髓梗死等严重并发症:结论:在 BAE 之后安全地进行了气道支架置入术,未出现严重出血或急性呼吸衰竭。在 BAE 之后进行气道支架置入术是非常有用的。

Background

Acute exacerbation (AE) is a potentially lethal event in patients with usual interstitial pneumonia/idiopathic pulmonary fibrosis (UIP/IPF). However, to date, no pathological predictors of AE have been identified. This retrospective study aimed to elucidate the pathological features that could predict AE in patients with UIP.

Methods

We reviewed the pathological findings of 91 patients with UIP/IPF and correlated these findings with AE events. Thirteen histological variables related to acute lung injury were evaluated by three independent observers and classified as positive or negative. The patients’ clinical data during follow-up were collected and reviewed for AE. A recursive partition using the Gini index for the prediction of AE was performed, with each pathological finding as a candidate for branching.

Results

Twenty patients (22%) developed AE during the median follow-up duration of 40 months. Thirty-eight patients died (15 due to AE and 23 for other reasons). The median time interval from surgical lung biopsy to AE onset was 497 (interquartile range: 901–1657) days. Histologically, squamous metaplasia was positively associated with AE (odds ratio: 4.7, P = 0.015) and worse event-free survival in patients with UIP (P = 0.04). Leaf scoring based on the Gini index for recursive partition, including five positive findings (squamous metaplasia, neutrophilic infiltration, septal widening, Kuhn's hyaline, and fibrin), showed a sensitivity of 90% with a specificity of 74.7% (area under curve: 0.89).

Conclusions

We found that squamous metaplasia is an important histopathological finding that predicts AE events and tends to unfavorable outcome in patients with UIP/IPF.

背景急性加重(AE)是常发性间质性肺炎/特发性肺纤维化(UIP/IPF)患者的一种潜在致命疾病。然而,迄今为止,尚未发现急性加重的病理预测因素。这项回顾性研究旨在阐明可预测 UIP 患者 AE 的病理特征。方法我们回顾了 91 例 UIP/IPF 患者的病理结果,并将这些结果与 AE 事件相关联。由三名独立观察员对与急性肺损伤相关的13个组织学变量进行评估,并将其分为阳性和阴性。收集了患者随访期间的临床数据,并对 AE 进行了审查。结果在中位 40 个月的随访期间,20 名患者(22%)出现了急性肺损伤。38名患者死亡(15人死于AE,23人死于其他原因)。从手术肺活检到 AE 发生的中位时间间隔为 497 天(四分位间范围:901-1657)。从组织学角度看,鳞状化生与 AE 呈正相关(几率比:4.7,P = 0.015),且 UIP 患者的无事件生存率较低(P = 0.04)。根据吉尼指数对复发分区进行叶片评分,包括五项阳性发现(鳞状化生、中性粒细胞浸润、室间隔增宽、Kuhn 透明层和纤维蛋白),结果显示敏感性为 90%,特异性为 74.7%(曲线下面积:0.89)。

Background

Several studies have suggested a potential correlation between menopause and airflow limitation. However, the presence of protective factors in postmenopausal women remains uncertain. Therefore, our study seeks to examine potential protective factors associated with a reduced prevalence of airflow limitation among postmenopausal women.

Methods

Postmenopausal women were recruited from the Taiwan Biobank for this cross-sectional study. Airflow limitation was defined by a forced expiratory volume in the first second (FEV1)/forced vital capacity (FVC) ratio <0.7. The participants were categorized into two groups: non-coffee drinkers and coffee drinkers, and the association between coffee consumption and airflow limitation was examined using binary logistic regression models.

Results

A total of 8149 women with available information were enrolled. Compared to the non-coffee drinkers, the coffee drinkers had a significantly lower prevalence of airflow limitation (7% vs. 5%). The odds ratio (OR) for airflow limitation was lower in the coffee drinkers than in the non-coffee drinkers (OR = 0.77; 95% confidence interval [CI] = 0.63 to 0.94) after adjusting for confounding factors. We also examined the association between daily coffee consumption in cups and airflow limitation. The women who consumed ≥2 cups of coffee per day had an OR of 0.74 (95% CI = 0.59 to 0.94) compared to those who did not consume coffee.

Conclusions

Our results suggest that habitual coffee consumption is associated with a reduction in the prevalence of airflow limitation in postmenopausal women, warranting further prospective studies to explore possible causal effects and mechanisms.

背景多项研究表明,绝经与气流受限之间存在潜在的相关性。然而,绝经后妇女是否存在保护性因素仍不确定。因此,我们的研究试图探讨与绝经后妇女气流受限患病率降低相关的潜在保护因素。气流受限的定义是第一秒用力呼气容积(FEV1)/用力生命容量(FVC)比值大于 0.7。研究人员将参与者分为两组:不喝咖啡者和喝咖啡者,并使用二元逻辑回归模型研究了喝咖啡与气流受限之间的关系。与不喝咖啡的人相比,喝咖啡的人气流受限的发生率明显较低(7% 对 5%)。在对混杂因素进行调整后,喝咖啡者气流受限的几率比(OR)低于不喝咖啡者(OR = 0.77;95% 置信区间 [CI] = 0.63 至 0.94)。我们还研究了每日咖啡饮用量与气流受限之间的关系。结论我们的研究结果表明,习惯性饮用咖啡与绝经后妇女气流受限患病率的降低有关,因此有必要进一步开展前瞻性研究,以探索可能的因果效应和机制。

Background

Thoracoscopy is useful for diagnosing unexplained pleural effusions. A sufficient specimen volume is often difficult to obtain using forceps biopsies (FBs) but can be obtained with pleural cryobiopsies (CBs). This study aimed to assess the utility and safety of CB during thoracoscopy in the Japanese population.

Methods

Patients who underwent thoracoscopic CBs at the Japanese Red Cross Medical Center between January 2017 and August 2023 were included in the study. Data were retrospectively analyzed, including clinical data, thoracoscopic findings, specimen size, diagnostic yield, and complications. The number of collected specimens and the freezing time were left to the discretion of the attending physician.

Results

Twenty-six patients underwent thoracoscopic CB. Specimens obtained by CB were larger than those obtained by FB. Primary lung cancer was the most common cause of pleural effusion, followed by malignant pleural mesothelioma. CB contributed to the diagnosis in 24 of 26 cases (92.3%) and FB contributed to the diagnosis in 11 of 18 cases (61.1%). Severe fibrosis could be diagnosed in all 3 cases by CB, but not by FB. The common complications of CB included bleeding at the biopsy site and atelectasis, but no severe complications occurred.

Conclusions

The utility and safety of thoracoscopic CB for diagnosing pleural effusions in Japan were verified. The diagnostic yield, specimen size, and safety profile of CB support the diagnostic utility of this method.

背景胸腔镜检查有助于诊断原因不明的胸腔积液。使用镊子活检(FB)往往难以获得足够的标本量,但使用胸膜冷冻活检(CB)则可获得足够的标本量。本研究旨在评估日本人群在胸腔镜检查过程中使用 CB 的实用性和安全性。研究纳入了 2017 年 1 月至 2023 年 8 月期间在日本红十字医疗中心接受胸腔镜 CB 检查的患者。对数据进行回顾性分析,包括临床数据、胸腔镜检查结果、标本大小、诊断率和并发症。采集标本的数量和冷冻时间由主治医生决定。CB 取得的标本比 FB 取得的标本大。原发性肺癌是胸腔积液最常见的原因,其次是恶性胸膜间皮瘤。在26例胸腔积液中,有24例(92.3%)是通过CB确诊的,而在18例胸腔积液中,有11例(61.1%)是通过FB确诊的。所有 3 个病例都能通过 CB 诊断出严重纤维化,但不能通过 FB 诊断出严重纤维化。结论 在日本,胸腔镜 CB 诊断胸腔积液的实用性和安全性得到了验证。胸腔镜活检的诊断率、标本大小和安全性都证明了这种方法的诊断效用。

Background

Pulmonary alveolar proteinosis (PAP) is characterized by an abnormal accumulation of surfactants in the alveoli. Most cases are classified as autoimmune PAP (APAP) because they are associated with autoantibodies against granulocyte-macrophage colony-stimulating factor (GM-CSF). However, GM-CSF autoantibody levels are unlikely to correlate with the disease severity or prognosis of APAP.

Methods

We collected clinical records and measured 38 serum cytokine concentrations for consecutive patients with APAP. After exclusion of 21 cytokines because of undetectable levels, 17 cytokine levels were compared between low and high disease severity scores (DSSs). We also compared whole lung lavage (WLL)-free survival with cut-off values defined by receiver operating characteristic (ROC) curves of cytokine levels and WLL administration at 11 months.

Results

Nineteen patients with APAP were enrolled in the study. Five were classified as DSS 1 or 2, while the others were classified as DSS 4 or 5. Comparison between DSS 1−2 and 4−5 revealed that the concentrations of IP-10 and GRO increased in the latter groups (p < 0.05). Fifteen patients underwent WLL. Comparison between those who underwent WLL within 11 months and the others showed that IP-10 and TNF-α were tended to be elevated in the former group (p = 0.082 and 0.057, respectively). The cut-off values of IP-10, 308.8 pg/mL and TNF-α, 19.1 pg/mL, defined by the ROC curves, significantly separated WLL-free survivals with log-rank analyses (p = 0.005).

Conclusions

The concentrations of IP-10 and GRO may reflect the DSSs of APAP. A combination of IP-10 and TNF-α levels could be a biomarker to predict WLL-free survival.

背景肺泡蛋白沉积症(PAP)的特征是肺泡中表面活性物质的异常积聚。大多数病例被归类为自身免疫性肺泡蛋白沉积症(APAP),因为它们与针对粒细胞-巨噬细胞集落刺激因子(GM-CSF)的自身抗体有关。然而,GM-CSF 自身抗体水平不太可能与 APAP 的疾病严重程度或预后相关。方法我们收集了 APAP 连续患者的临床记录,并测量了 38 种血清细胞因子浓度。由于无法检测到 21 种细胞因子,我们将其排除在外,然后比较了疾病严重程度评分(DSS)低和高的 17 种细胞因子水平。我们还比较了细胞因子水平的接收器操作特征曲线(ROC)和 11 个月的全肺灌洗(WLL)无肺梗死生存率。五名患者被划分为 DSS 1 或 2,其他患者被划分为 DSS 4 或 5。对 DSS 1-2 和 4-5 组进行比较后发现,IP-10 和 GRO 的浓度在后一组中有所增加(p < 0.05)。15 名患者接受了 WLL。将在 11 个月内接受 WLL 的患者与其他患者进行比较,发现前者的 IP-10 和 TNF-α 有升高的趋势(p = 0.082 和 0.057)。ROC曲线确定的IP-10 308.8 pg/mL和TNF-α 19.1 pg/mL的临界值在对数秩分析中显著区分了无WLL存活率(p = 0.005)。IP-10和TNF-α水平的组合可作为预测无WLL生存率的生物标志物。

Background

The association between reflux esophagitis and pulmonary function remains controversial. Thus, evaluating the relationship between endoscopic reflux esophagitis and changes in pulmonary function over time in a nonsmoking population is an important clinical issue.

Methods

In this single-center retrospective cohort study, a medical examination database at Kameda Medical Center Makuhari was employed to identify nonsmokers who underwent upper gastrointestinal endoscopy and spirometry in 2010 and were followed up in 2015. Gastroenterologists carefully double-checked the diagnosis of reflux esophagitis. Multiple linear regression analyses were performed to compare the decline in the percentage of predicted vital capacity (%VC), forced vital capacity (%FVC), and forced expiratory volume in 1 s (%FEV1) between participants with reflux esophagitis and those without. Furthermore, using multivariable logistic regression analyses, we evaluated the factors associated with rapid decline in %VC, %FVC, and %FEV1, which is defined as a decrease of >10% in each parameter over the 5-year observation period.

Results

We identified 3098 eligible subjects, including 72 and 44 participants who had a Los Angeles classification grade A and B–C (severe) reflux esophagitis in 2010, respectively. The decline in %VC was significantly larger in the participants with severe reflux esophagitis than in the control subjects (standardized coefficient, −0.037; 95% confidence interval, −0.071 to −0.004). Moreover, reflux esophagitis was significantly associated with a rapid decline in %VC and %FVC but not in %FEV1 (P for trend: 0.009, 0.009, and 0.276, respectively).

Conclusions

Severe reflux esophagitis among nonsmokers had clinical disadvantages in terms of a decline in %VC.

背景反流性食管炎与肺功能之间的关系仍存在争议。因此,在非吸烟人群中评估内镜反流性食管炎与肺功能随时间变化之间的关系是一个重要的临床问题。方法在这项单中心回顾性队列研究中,研究人员利用龟田医疗中心幕张医疗中心的体检数据库,对 2010 年接受上消化道内镜检查和肺活量测定并在 2015 年接受随访的非吸烟者进行了识别。消化内科医生对反流性食管炎的诊断进行了仔细的双重检查。研究人员进行了多元线性回归分析,以比较有反流性食管炎和没有反流性食管炎的参试者的预测肺活量百分比(%VC)、用力肺活量(%FVC)和 1 秒用力呼气容积(%FEV1)的下降情况。此外,我们还使用多变量逻辑回归分析评估了与 %VC、%FVC 和 %FEV1 快速下降相关的因素,即在 5 年的观察期内每项参数下降 >10%。与对照组相比,患有严重反流性食管炎的受试者的 VVC 百分比下降幅度明显更大(标准化系数,-0.037;95% 置信区间,-0.071 至 -0.004)。此外,反流性食管炎与 %VC 和 %FVC 的快速下降显著相关,但与 %FEV1 的快速下降无关(趋势的 P 值分别为 0.009、0.009 和 0.276)。
