Automated CT-based measurements of radial and longitudinal expansion of airways due to breathing-related lung volume change.

Background: Respiratory function is impaired in chronic obstructive pulmonary disease (COPD). Automation of multi-volume CT-based measurements of different components of breathing-related airway deformations will help understand multi-pathway impairments in respiratory mechanics in COPD.

Purpose: To develop and evaluate multi-volume chest CT-based automated measurements of breathing-related radial and longitudinal expansion of individual airways between inspiratory and expiratory lung volumes.

Unexplained disabling and long-lasting cough: a case report.

Background: A 51-year-old woman was referred to our department due to chronic dry cough lasting six years without an etiological diagnosis. The patient suffered from chronic deterioration in her quality of life due to a persistent cough that sounded like a barking seal.

Case Presentation: A severe form of malacia involving the inferior third of trachea and the main bronchi was diagnosed.

Tuberculosis Masquerading Foreign Body in Children.

Foreign body aspiration (FBA) is a common issue in children, particularly boys, and can be life-threatening. Early removal of the foreign body (FB) leads to recovery, but delayed diagnosis may cause complications such as granuloma, recurrent pneumonia, and atelectasis. This condition often results from a child's curiosity, with factors such as inadequate swallowing reflex and activity during eating contributing to the risk.

Difficult airway foreign body removal.

Foreign body (FB) aspiration in children is a common emergency. Traditionally, rigid bronchoscopy has been considered to be the mainstay for removal. However, in certain cases, flexible bronchoscopy can prove to be a better option and avoid thoracic surgery and unnecessary morbidity.

Mortality and cancer incidence in the UK glass reinforced plastics manufacturing industry: a cohort study.

Objectives: According to the International Agency for Research on Cancer, styrene is probably carcinogenic for lymphohaematopoietic neoplasms, with insufficient evidence for other cancer sites. We compared mortality and cancer incidence (for the first time) in a UK cohort occupationally exposed to high levels of styrene to that of the general population of England and Wales.

Methods: The follow-up for mortality ran from 1969 to 2022, while the follow-up for cancer incidence ran from 1971 to 2020.

Extracorporeal Membrane Oxygenation With Robotic-Assisted Thoracic Surgery for Treatment of Giant Mediastinal Liposarcoma.

A 61-year-old woman presented to our team with giant mediastinal liposarcoma causing compression of the esophagus, bronchus, and left atrium. Given the patient's advanced presentation and reduced cardiac reserve, rescue venoarterial extracorporeal membrane oxygenation was used in addition to standard robotic-assisted thoracic surgery for mass resection.

The Correlation Analysis Between m6A Methylation Modification and Ferroptosis Induced by Cigarette Smoke in Human Bronchial Epithelium.

Background: Chronic obstructive pulmonary disease (COPD), a prevalent respiratory condition, is characterized by long-term airway inflammation, which can lead to airway remodeling and persistent airflow restriction. Exposure to cigarette smoke is known as a major contributor to COPD development. Research has confirmed that ferroptosis and m6A modification are closely related to various inflammatory-related diseases.

Fatty acid traits mediate the effects of uric acid on cancers: a Mendelian randomization study.

Introduction: Previous findings on the association between uric acid (UA) levels and cancer risk are conflicting. Moreover, the mechanisms underlying the interactions between UA levels, fatty acid traits, and cancer outcomes remain complex; it is still unclear whether elevated UA levels influence fatty acid traits and, thereby, contribute to an increased cancer risk. Therefore, we aimed to investigate the association between UA levels and cancer risk, with a specific focus on the potential mediating role of fatty acid traits.

Novel Strategies for Lung Cancer Interventional Diagnostics.

Lung cancer is a major global health issue, with 2.21 million cases and 1.80 million deaths reported in 2020.

Intraoperative Transbronchial Metallic Coil Marking for Small Peripheral Pulmonary Lesions in a Hybrid Operation Room.

: Computed tomography (CT)-guided transbronchial metallic coil marking is useful for identifying the locations of small peripheral pulmonary lesions. Even deeply located lesions may be accurately identified and resected with adequate margins. This method is also applicable to multiple lesions.

Free Methylglyoxal as a Metabolic New Biomarker of Tumor Cell Proliferation in Cancers.

Background: A fundamental property of cancer cells is their metabolic reprogramming, allowing them to increase glucose uptake and glycolysis. Using a rat colon adenocarcinoma model, we previously showed that blood levels of free methylglyoxal (MG), a side-product of glycolysis, remained normal in animals grafted with a non-growing tumor cell clone, while MG levels were significantly increased and positively correlated with tumor growth in animals grafted with a tumorigenic cell clone issued from the same tumor.

Methods: We measured free MG in the blood of cancerous non-diabetic patients and compared the results to healthy subjects and non-cancerous diabetic patients.

Protective effect of interferon type I on barrier function of human airway epithelium during rhinovirus infections in vitro.

The airway epithelium provides a crucial barrier against infection with respiratory pathogens. This barrier can be impaired following viral infection, paving the way for bacterial superinfections. Type I interferons (IFNs) are important antiviral mediators, and inhaled formulations of these glycoproteins are considered a potential approach for the treatment of respiratory viral infections.

Intraoperative transbronchial metallic coil marking guided by mobile 3D C-arm for resection of a small peripheral lung lesion.

Sublober resection of small peripheral lung lesions using video-assisted thoracoscopic surgery may require marking and confirmation using 3D imaging in the interventional radiology suite or in the hybrid operating room (HOR) before surgery is started. We report a novel approach for intraoperative transbronchial metallic coil marking followed by thoracoscopic wedge resection in a conventional operating room under mobile 3D C-arm guidance. Under general anesthesia, an ultrathin video-bronchoscope was inserted into an objective bronchus guided with virtual bronchoscopic navigation, and a coil-feeding microcatheter was introduced through the bronchoscope's channel.

Comparison of Synapse 3D system (Version 4.4) and DirectPath system (Version 2.0) in virtual bronchoscopic navigation application for peripheral pulmonary nodules.

Background: Differences between virtual bronchoscopic navigation (VBN) systems and their impacts on the diagnostic yield of transbronchial biopsy (TBB) of peripheral pulmonary nodules (PPNs) remain unclear.

Objectives: To compare the Synapse 3D system (Version 4.4, Fujifilm, Japan) and DirectPath system (Version 2.

[Metastatic Lung Tumor with Bronchial Cast Shadow in Which Intraoperative Bronchoscopy Was Useful During Robotic Surgery].

A man in his 60s, who had undergone surgery for rectal cancer, liver metastases, and lung metastasis, had a past history of myocardial infarction and ventricular fibrillation with reduced cardiac functions. He was referred to our department because of a pulmonary nodule shadow in the S2 right upper lobe and a bronchial cast shadow along the B2 bronchus. Robot-assisted thoracoscopic right S2 segmentectomy was performed and intraoperative bronchoscopy revealed a polyp-like tumor within B2a.

[Delayed Lung Resection for Retrieval of an Aspirated Dental Crown:Report of a Case].

Association Between Pulmonary Tuberculosis and Bronchial Anthracosis.

Introduction Anthracosis is black discoloration of the bronchi, which can sometimes cause anthracofibrosis. Usually, exposure to biomass fuel, air pollution, or smoke at the workplace causes it. The objective of the current study was to determine the association between tuberculosis and anthracosis.

Fatal Tracheal and Bronchial Destruction Due to Pulmonary Mucormycosis in a 20-Year-Old with Diabetic Ketoacidosis.

Pulmonary mucormycosis is a rare and aggressive invasive fungal infection that predominantly affects immunocompromised individuals, such as those with diabetes mellitus or those undergoing immunosuppressive therapy. This case describes a severe instance of pulmonary mucormycosis resulting in progressive tracheal wall destruction in a young, previously healthy male. A 20-year-old male with a denied history of diabetes mellitus was admitted to a local hospital with abdominal pain for 9 days and diagnosed with acute pancreatitis and diabetic ketoacidosis (DKA).

Uniportal thoracoscopic posterior basal (S10) segmentectomy using a posterior approach.

Performing a posterior basal (S10) segmentectomy through a single port is challenging because of the dorsal location of the S10 segment in the lower lobe. The vessels and bronchi to be resected are located deep and away from the major fissure, which makes exposure from the interlobar fissure difficult. To avoid unnecessary parenchymal splitting and potential misrecognition of segmental structures, we performed a uniportal thoracoscopic S10 segmentectomy via a posterior approach without extensively separating the pulmonary parenchyma from the interlobar fissure.

Diagnostic Performance of Imaging Methods in Predicting Lung Cancer Metastases.

Objective: This study aimed to investigate the possibility of distant organ metastasis using an algorithm developed to evaluate the morphology and localization of lung masses.

Methods: Patients diagnosed with lung cancer between 2016 and 2023 were included. The lesion's morphological characteristics, proximity to important structures, and maximum standardized uptake value were recorded.

First in Human Evaluation of a Novel Thin Convex Probe Endobronchial Ultrasound System.
