Impact of immune-related adverse events on survival outcomes in extensive-stage small cell lung cancer patients treated with immune checkpoint inhibitors.

Background: Immune checkpoint inhibitors have recently become the standard of care in the first-line treatment of extensive-stage small cell lung cancer. Although immune-related adverse events have been reported to influence prognosis in non-small cell lung cancer patients, few studies have investigated the prognostic value of immune-related adverse events in small cell lung cancer patients. In this study, we evaluated the prognosis of patients who developed immune-related adverse events after first-line treatment with immune checkpoint inhibitor-based chemotherapy for extensive-stage small cell lung cancer.

Is the Efficacy of Adding Ramucirumab to Docetaxel Related to a History of Immune Checkpoint Inhibitors in the Real-World Clinical Practice?

Reports on the efficacy of second-line treatment with cytotoxic agents after treatment with immune checkpoint inhibitors are limited. Here, we retrospectively evaluated patients in the real-world clinical practice treated with docetaxel or docetaxel plus ramucirumab. Ninety-three patients treated with docetaxel or docetaxel plus ramucirumab as a second- or later-line therapy were included.

Extensive calcification in adenocarcinoma of the lung: A case report.

Calcification in lung nodules usually indicates a benign lesion. Here, we report the case of a 59-year-old male patient with a well defined 30 mm calcified nodule in his right upper lung lobe and calcified mediastinal lymph nodes. The mass was diagnosed as adenocarcinoma by transbronchial biopsy.

Three-dimensional computed tomography angiography for the preoperative evaluation of coronary artery disease in lung cancer patients.

Background: The number of elderly patients undergoing surgery for lung cancer is increasing. In this study, we assessed the usefulness of three-dimensional computed tomographicangiography (3D-CTA) for the detection of coronary disease in the elderly before surgical intervention for lung cancer.

Methods: One hundred twenty patients admitted to our institution for lung cancer resection were enrolled in the study.

Thrombin-activatable fibrinolysis inhibitor protects against acute lung injury by inhibiting the complement system.

Acute lung injury (ALI) is a devastating disease with an overall mortality rate of 30 to 40%. The coagulation/fibrinolysis system is implicated in the pathogenesis of ALI. Thrombin-activatable fibronolysis inhibitor (TAFI) is an important component of the fibrinolysis system.

Eosinophils promote epithelial to mesenchymal transition of bronchial epithelial cells.

Eosinophilic inflammation and remodeling of the airways including subepithelial fibrosis and myofibroblast hyperplasia are characteristic pathological findings of bronchial asthma. Epithelial to mesenchymal transition (EMT) plays a critical role in airway remodelling. In this study, we hypothesized that infiltrating eosinophils promote airway remodelling in bronchial asthma.

Indacaterol improves daily physical activity in patients with chronic obstructive pulmonary disease.

Background: The current mainstay of therapy for chronic obstructive pulmonary disease (COPD) is long-acting bronchodilators. To date, the effect of indacaterol, a β2-agonist, on activities of daily living in COPD patients is not well understood. The aim of this study was to evaluate the efficacy of indacaterol with regard to activities of daily living in patients with COPD.

Efficacy of a novel class of RNA interference therapeutic agents.

RNA interference (RNAi) is being widely used in functional gene research and is an important tool for drug discovery. However, canonical double-stranded short interfering RNAs are unstable and induce undesirable adverse effects, and thus there is no currently RNAi-based therapy in the clinic. We have developed a novel class of RNAi agents, and evaluated their effectiveness in vitro and in mouse models of acute lung injury (ALI) and pulmonary fibrosis.

Differential role of regulatory T cells in early and late stages of pulmonary fibrosis.

Regulatory T cells (Tregs) are a specific subset of T lymphocytes that regulate the function of other subsets of lymphocytes. Contradictory results have been reported regarding the role of Tregs in lung fibrosis. We wished to clarify the role of Tregs in the early and late stages of bleomycin-induced lung fibrosis in mice by depleting them with anti-CD25+ antibody (PC61).

Correlation between circulating fibrocytes, and activity and progression of interstitial lung diseases.

Background And Objective: Interstitial lung diseases (ILD) are characterized by progressive interstitial pulmonary fibrosis and a decline in lung function. Fibrocytes are bone marrow-derived mesenchymal progenitor cells that may play a role in the pathogenesis of pulmonary fibrosis. Circulating fibrocyte numbers have been correlated with the prognosis of patients with idiopathic pulmonary fibrosis.

Role of thrombin-activatable fibrinolysis inhibitor in allergic bronchial asthma.

Background: Bronchial asthma is an inflammatory disease of the airways. Thrombin-activatable fibrinolysis inhibitor (TAFI) is a carboxypeptidase that besides inhibiting fibrinolysis, also regulates inflammatory processes. The only validated substrate known for TAFI is fibrin.

Solitary pulmonary nodule of benign metastasizing leiomyoma associated with primary lung cancer: a case report.

Introduction: Benign metastasizing leiomyoma in the lung is a very rare disease characterized by the growth of uterine leiomyoma tissue. In most cases there is a previous history of hysterectomy for uterine leiomyoma.

Case Presentation: A 50-year-old Asian woman underwent a total abdominal hysterectomy for uterine leiomyoma at the age of 37 years old.

Community-acquired pneumonia and nursing home-acquired pneumonia in the very elderly patients.

The rapid increase in the elderly population is leading to a corresponding increase in the number of people requiring medical care. To date no comparative study between community-acquired pneumonia (CAP) and nursing home-acquired pneumonia (NHAP) has been reported in the very elderly non-intubated patients. The present study was undertaken to compare the clinical characteristics and microbial etiology between CAP and NHAP in elderly patients >/=85-years old.
