Background: The underlying pathophysiology of varying physical activity levels in patients with asthma remains unclear. In this study, we investigated the association between physical activity and air trapping, identified via chest computed tomography, in patients with asthma.
Methods: The following computed tomography analyses were used to evaluate air trapping in two cohorts (Cohort 1: 27 patients with asthma, 12 healthy individuals; Cohort 2: 90 patients with asthma, 43 healthy individuals): density analysis, focusing on air trapping characteristics during expiration, and parametric response mapping (PRM), which integrates inspiratory and expiratory computed tomography scans to categorize air trapping into small airway disease (PRM) and low-attenuation areas.
Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors are effective for treating EGFR mutation-positive non-small cell lung cancer. However, the diversity of EGFR mutations presents a challenge, as treatment strategies for rare variants remain undefined. A 29-year-old nonsmoking man presented to his primary physician in September 2019 with back pain.

The efficacy and risks of treatment remain unknown and no standard chemotherapy regimen has been established for this condition. The central institutional review board approved this study.

However, the systemic effect of physical activity, especially sedentary behavior, in patients with asthma remains unclear.
Objective: The aim of this study was to investigate the association of objectively measured physical activity, including sedentary time, with body composition data and clinical characteristics in patients with asthma.
Invasive pneumococcal disease (IPD) has a high fatality rate; however, its severity varies by pneumococcal serotype. Serotype 1 is often associated with empyema but typically has a low fatality rate, and IPD is rarely reported in such cases. We report the case of a 68-year-old man who developed IPD with systemic abscesses, including empyema, purulent pericardial effusion, and an intramuscular abscess in the right thigh, along with sepsis caused by serotype 1 .

Background: Despite the poor prognosis of advanced or recurrent thymic carcinoma, the rarity of thymic carcinoma has delayed the development and introduction of novel pharmacotherapy options. Carboplatin plus paclitaxel remains a standard treatment for chemotherapy-naive advanced or recurrent thymic carcinoma. We evaluated the activity and safety of atezolizumab combined with chemotherapy.

Background: There is an increased risk of acute exacerbation of idiopathic interstitial pneumonia when treating patients with advanced non-small cell lung cancer with idiopathic interstitial pneumonia. There is no standard optimal treatment regimen for patients with lung cancer complicated with idiopathic interstitial pneumonia. We aimed to evaluate the efficacy and safety of carboplatin (CBDCA), bevacizumab (Bmab) and weekly paclitaxel (PXT) in patients with idiopathic interstitial pneumonia.

Primary lung cancer with pulmonary alveolar proteinosis (PAP) is a rare condition. We present a case of a patient with primary lung cancer with PAP treated with an immune checkpoint inhibitor (ICI). A 62-year-old man was diagnosed with autoimmune PAP 8 years prior to current admission.

Strain differences must be considered when selecting mouse models of COPD, owing to disease complexity. We previously reported that a novel C57BL/6JJcl substrain, the Mayumi-Emphysema (ME) mouse, exhibits spontaneous emphysema; however, the other characteristics remain unknown.

Dysphagia and diffuse ground-glass shadows on computed tomography led to the diagnosis of esophageal achalasia. An analysis of bronchoalveolar lavage (BAL) revealed yellow BAL fluid, with two distinct layers.

Although randomized controlled trials have examined the effects of pneumococcal vaccines, few epidemiological studies have investigated the onset of pneumococcal pneumonia in general practice. In Izumo, Shimane Prefecture, Japan, a public subsidy for PPSV23 inoculation began in November 2012.

Background: Asthma is a highly heterogeneous airway disease, and the clinical characteristics of patients with asthma with preserved and reduced physical activity are poorly understood.
Objective: We aimed to investigate the risk factors and clinical phenotypes associated with reduced physical activity in a wide range of patients with asthma.
Methods: We conducted a prospective observational study of 138 patients with asthma, including patients with asthma without chronic obstructive pulmonary disease (COPD) (n = 104) and asthma-COPD overlap (n = 34), and 42 healthy controls.
We performed endocytoscopy (ECS) for the ex vivo evaluation of mesothelioma in specimens biopsied during medical thoracoscopy in three patients. We evaluated 19 biopsy specimens based on the density of nuclei and irregularity in the nuclei shape using ECS and compared them with the histopathological findings. All 10 specimens considered malignant based on ECS were diagnosed as malignant based on histopathology.

Insulin-like growth factor-I receptor (IGF-1R) inhibitor is a candidate for treating pemetrexed-naïve MPM. However, the efficacy of cytotoxic and targeted drugs in acquired-pemetrexed resistant MPM is unclear.

In this retrospective study, we aimed to evaluate whether the Glasgow Prognostic Score (GPS), an indicator of systemic inflammation and malnutrition, could predict the tolerability and efficacy of platinum-combination chemotherapy among elderly patients with NSCLC. Methods : The eligibility criteria included patients aged ≥ 70 years with NSCLC treated with first-line platinum-combination chemotherapy at Shimane University Hospital between January 2015 and December 2018.

Background: Multiple synchronous ground glass nodules (GGNs) are known to be malignant, however, they tend to progress slowly. Multiple synchronous lesions in the same patient which show different characteristics must be treated individually.
Methods: This was a retrospective review of 34 lung adenocarcinoma patients with multiple synchronous GGNs in an Asian population.
