Preserved ratio impaired spirometry (PRISm), defined as a forced expiratory volume in 1 s (FEV1) to forced vital capacity (FVC) ratio ≥0.70 and a predicted FEV1 <80 %, is associated with increased morbidity and mortality. However, determinants of PRISm, particularly in younger populations, remain poorly characterised. We aimed to address this knowledge gap.
Methods
We conducted a cross-sectional analysis of 12,350 participants from a Japanese community-based cohort using data from the Tohoku Medical Megabank Project. Participants underwent spirometry, blood pressure measurement, laboratory testing, and completed standardised questionnaires. Multivariate logistic regression was used to identify factors associated with PRISm across three age groups: 20–39, 40–59, and ≥60 years. Interactions between age groups and other explanatory variables were assessed.
Results
In the 20–39-year group, PRISm was independently associated with being men, diabetes mellitus, hypothyroidism, and low body mass index (BMI <18.5 kg/m2), and inversely associated with age. Among participants aged ≥60 years, PRISm was significantly associated with increasing age, overweight status (BMI ≥25.0–<30.0 kg/m2), being men, current smoking, hypertension, diabetes mellitus, bronchial asthma, elevated eosinophil counts (≥300 cells/μL), and birth weight ≥2000–<2500 g. Significant interactions were observed between age and BMI, bronchial asthma, and thyroid dysfunction.
Conclusions
Our findings indicate that PRISm in younger adults is associated with hypothyroidism and underweight status, whereas in older adults, it is more closely related to constitutional and lifestyle-related factors. These results highlight the heterogeneity of PRISm and indicate that its pathophysiology and optimal management may vary by age group.

There is limited data on BRAF V600E-mutant squamous cell carcinoma (SCC). We report three cases of SCC of the lung with a history of resected papillary thyroid carcinoma (PTC), showing p40 positivity, TTF-1 negativity, and PAX8 expression. While treated as lung SCC, metastatic thyroid carcinoma was unconfirmed due to absence of PTC recurrence, clinicopathologic features consistent with primary lung origin, and unavailable archival PTC pathology. BRAF inhibitors yielded only transient responses, and outcomes were poor. These cases underscore the diagnostic and therapeutic value of multigene testing in SCC, highlighting the need to integrate detailed clinical history into precision oncology strategies.

The 6-min walk test (6MWT) is a widely used functional test that assesses desaturation on exercise. However, the clinical impact of desaturation on progressive pulmonary fibrosis (PPF) has been insufficiently studied. We aimed to evaluate the association between desaturation and future progression in patients with fibrotic interstitial lung disease (FILD).
Methods
We retrospectively analysed consecutive patients with FILD from 2008 to 2015. Desaturation was defined as oxygen saturation measured by pulse oximetry (SpO2) at the end of the 6MWT being less than 90 %. It was divided into two groups: mild (SpO2 was 89 %) and moderate desaturation (SpO2 was 88 % or less).
Results
Among 810 patients, 498 (61.5 %) had desaturation (45 mild and 453 moderate). Multivariable Cox proportional hazard analysis showed desaturation was associated with a higher mortality (HR: 1.69, 95 % CI: 1.37–2.08, p < 0.0001). Both mild and moderate desaturation were also associated with a higher mortality compared with no desaturation, although there was no significant difference between them. Multivariable logistic regression analysis showed that desaturation was associated with PPF in the overall cohort (OR: 2.20, 95 % CI: 1.59–3.05, p < 0.0001), in patients with idiopathic pulmonary fibrosis (IPF) (OR: 2.59, 95 % CI: 1.56–4.29, p = 0.0002), and in patients with non-IPF FILD (OR: 1.86, 95 % CI: 1.17–2.96, p = 0.0091).
Conclusions
Desaturation in the 6MWT was associated with future risk of progression in patients with newly diagnosed FILD.
6分钟步行测试(6MWT)是一种广泛使用的功能测试,用于评估运动时的去饱和。然而,去饱和对进行性肺纤维化(PPF)的临床影响尚未得到充分研究。我们旨在评估纤维化间质性肺疾病(field)患者去饱和与未来进展之间的关系。方法回顾性分析2008 - 2015年连续发生的field患者。去饱和定义为在6MWT结束时通过脉搏血氧仪(SpO2)测量的氧饱和度小于90%。分为轻度(SpO2为89%)和中度(SpO2为88%或以下)两组。结果810例患者中有498例(61.5%)发生过血饱和度过低,其中轻度45例,中度453例。多变量Cox比例风险分析显示,去饱和与较高的死亡率相关(HR: 1.69, 95% CI: 1.37-2.08, p < 0.0001)。与不去饱和相比,轻度和中度去饱和也与更高的死亡率相关,尽管两者之间没有显著差异。多变量logistic回归分析显示,在整个队列(OR: 2.20, 95% CI: 1.59-3.05, p < 0.0001)、特发性肺纤维化(IPF)患者(OR: 2.59, 95% CI: 1.56-4.29, p = 0.0002)和非IPF field患者(OR: 1.86, 95% CI: 1.17-2.96, p = 0.0091)中,去饱和与PPF相关。结论:6MWT的去饱和与新诊断的field患者未来的进展风险相关。

Background
There are no available data on the impact of hospitalization on health-related quality of life (HRQoL) in patients receiving home oxygen therapy (HOT). Thus, the present study aimed to examine the association between hospitalization and HRQoL in patients receiving HOT based on the results of the Japanese White Paper on Home Respiratory Care 2024.
Methods
Patients receiving HOT who completed the HRQoL section of the patient survey, assessed using the Short Form-8 (SF-8) questionnaire, were included in the analysis. This survey data were collected from December 2021 to March 2023. The SF-8 questionnaire comprised eight subitems and two summary scores (physical component summary [PCS] and mental component summary [MCS]). Hospitalization within the past year were evaluated, excluding those due to coronavirus disease 2019.
Results
Totally, 288 patients receiving HOT were examined. In the SF-8 questionnaire survey, all items except body pain and the two summary scores did not differ between patients with chronic obstructive pulmonary disease and those with interstitial lung disease. Patients who had history of hospitalization had lower scores in all eight subitems and in both summary scores than those who did not. Based on a stepwise multiple linear regression analysis, PCS (β = −0.14, p = 0.011) and MCS (β = −0.14, p = 0.014) scores were independently and negatively correlated with hospitalization.
Conclusions
A history of hospitalization was independently associated with reduced HRQoL in patients receiving HOT. Prospective studies are needed to clarify underlying mechanisms and to evaluate interventions that may minimize HRQoL decline.
背景:目前尚无关于住院治疗对接受家庭氧疗(HOT)患者健康相关生活质量(HRQoL)影响的数据。因此,本研究旨在基于日本家庭呼吸护理白皮书2024的结果,探讨住院与接受HOT患者HRQoL之间的关系。方法接受HOT治疗的患者完成患者调查的HRQoL部分,使用SF-8问卷进行评估,纳入分析。该调查数据收集于2021年12月至2023年3月。SF-8问卷包括8个小项目和2个综合得分(生理成分总结[PCS]和心理成分总结[MCS])。评估了过去一年内的住院情况,但不包括因2019年冠状病毒病住院的情况。结果共检查HOT患者288例。在SF-8问卷调查中,慢性阻塞性肺疾病患者与间质性肺疾病患者除身体疼痛和两项总结得分外,其他项目均无差异。有住院史的患者在所有八个分项和两项综合得分上的得分都低于没有住院史的患者。经逐步多元线性回归分析,PCS评分(β = - 0.14, p = 0.011)和MCS评分(β = - 0.14, p = 0.014)与住院治疗呈独立负相关。结论住院史与热疗患者HRQoL降低独立相关。需要前瞻性研究来阐明潜在的机制,并评估可能使HRQoL下降最小化的干预措施。

Bronchoscopic lung insufflation (BLI) allows re-expansion of collapsed lung lobes after transplantation. Among 254 transplant cases at our center, two patients underwent BLI for lobar atelectasis. Case 1 had recurrent right middle-lobe collapse after initial recovery, and BLI under conscious sedation led to durable re-expansion without complications. Case 2 underwent BLI for right upper-lobe atelectasis but developed transient neurological deficits due to presumed cerebral gas embolism, despite initial re-expansion. Full recovery was achieved with supportive care. These cases highlight BLI as an effective treatment for post-transplant atelectasis, although rare but serious complications require careful monitoring.

With proper patient selection excluding collateral ventilation, bronchoscopic lung volume reduction (BLVR) with endobronchial valves (EBVs) offers significant benefits but increases pneumothorax risk. Prioritized management of persistent pneumothorax post-BLVR remains unclear, with both EBV removal and video-assisted thoracic surgery (VATS) considered options. We report a 76-year-old man with severe emphysema who developed persistent pneumothorax and subcutaneous emphysema after left upper lobe BLVR. Following the patient's wishes, VATS was performed instead of EBV removal, resulting in a favorable outcome without delaying BLVR benefits. Depending upon the situation and patient wishes, prioritizing VATS over valve removal may be a reasonable strategy.

Biologic therapies have revolutionized the treatment of severe asthma. However, the selection of the optimal biologic agent remains challenging because of the heterogeneity of disease phenotypes and frequent comorbidities. This mini-review explored the clinical relevance of comorbidities in the selection of biologics for patients with asthma.
Herein, we summarize recent evidence on the prevalence of comorbidities associated with type 2 inflammation, including chronic spontaneous urticaria, atopic dermatitis, prurigo nodularis, chronic rhinosinusitis with nasal polyps, eosinophilic granulomatosis with polyangiitis, eosinophilic otitis media, aspirin-exacerbated respiratory disease, allergic rhinitis, allergic bronchopulmonary mycosis, obesity, and chronic obstructive pulmonary disease, and review the efficacy of five major biologics (omalizumab, mepolizumab, benralizumab, dupilumab, and tezepelumab) in these settings. Each biologic targets distinct immunologic pathways in type 2 inflammation, including IgE, IL-5, IL-5Rα, IL-4Rα, and thymic stromal lymphopoietin, respectively.
In conclusion, the assessment of comorbidities in addition to biomarkers is essential for tailoring biologic therapies for severe asthma. Integrating comorbidity profiles into treatment strategies allows for a more precise and effective use of biologics, ultimately improving outcomes in complicated asthma cases.

Sputum management is a critical and potentially lethal issue in patients following lung transplantation. Here, we describe a patient with idiopathic pleuroparenchymal fibroelastosis who underwent tracheotomy after deceased donor bilateral lung transplantation, in whom we were unable to remove the tracheostomy tube due to difficulty in sputum evacuation. The tube was successfully removed following the subsequent initiation of intrapulmonary percussive ventilation (IPV) treatment combined with pulmonary rehabilitation. IPV has been widely used for several decades for treating pulmonary conditions, including chronic obstructive pulmonary disease, cystic fibrosis, and bronchiectasis. However, it should also be considered for airway clearance after lung transplantation.

Venous thromboembolism (VTE) is a frequent complication of cancer-associated thrombosis, and its management is critical when considering cancer treatment selection and prognosis. The aim of this study was to investigate the incidence and risk factors for VTE in patients with lung cancer using the CS-Lung003 platform, a multicenter prospective observational study of advanced lung cancer.
Methods
Patients with a pathologic diagnosis of lung cancer at any stage were included. The incidence of VTE was calculated using the CS-Lung003 database, and risk factors were examined using logistic regression analysis.

The analysis included 1744 patients (80 % male). Sixty patients (3.4 %) had VTE at/after enrollment in the CS-Lung003 trial. The median age was 69 years (range 63–76) in the group without VTE and 72 years (range 67–77) in the group with VTE. Adenocarcinoma was diagnosed in 58.7 % of patients in the group without VTE and 46.7 % in the group with VTE. Univariate analysis revealed male sex, body weight, and hypertension as risk factors for VTE. Overall survival was 29.1 months in the group without VTE and 30.6 months in the group with VTE. Among patients with stage IIIB–IV, the VTE group showed significantly longer overall survival compared with the non-VTE group (p = 0.041).
Conclusions
The incidence of VTE in this study was low, suggesting that there may have been patients with VTE complications that were not reported in the registry. In addition, most patients with VTE received therapeutic intervention; appropriate diagnosis and treatment may have allowed cancer treatment to continue. Appropriate diagnosis and treatment of VTE might allow lung cancer therapy continuation without compromising survival.

Patients with interstitial lung disease (ILD) often experience psychological symptoms. This study aimed to clarify the status of psychological support for patients with ILD in Japan.
Methods
We conducted a secondary analysis on a nationwide survey of Japanese respiratory physicians to assess psychological support availability, consultation departments, reasons for palliative care referrals, and opinions on insurance coverage for psychologist-led psychotherapy.
Results
Of 1332 respondents, 1023 managed patients with ILD in the previous year. Among them, 34.5 % reported no psychological support availability and 42.9 % reported insufficient support. Psychiatry or psychosomatic medicine departments were consulted by 77.3 %, and palliative care teams by 52.2 %. Anxiety (47.4 %) and depression (44.6 %) were the reasons for palliative care referral. Overall, 93.6 % considered insurance coverage for psychologist-led psychotherapy helpful or essential.
Conclusions
Most physicians lack adequate psychological support resources for ILD despite frequent psychological symptoms. Systematic development of support structures and insurance coverage are needed.
