The utility of trans thoracic echocardiograhic measures of right ventricular systolic function in a lung resection cohort.

Right ventricular (RV) dysfunction occurs following lung resection and is associated with post-operative complications and long-term functional morbidity. Accurate peri-operative assessment of RV function would have utility in this population. The difficulties of trans thoracic echocardiographic (TTE) assessment of RV function may be compounded following lung resection surgery and no parameters ha...

Screening for Early Lung Cancer, Chronic Obstructive Pulmonary Disease, and Cardiovascular Disease (the Big-3) Using Low-dose Chest Computed Tomography: Current Evidence and Technical Considerations.

Lung cancer, chronic obstructive pulmonary disease, and cardiovascular disease are highly prevalent in the general population and expected to cause most deaths by 2050. For these "Big-3," treatment might cure, delay, or stop the progression of disease at a very early stage. Lung nodule growth rate (a biomarker for lung cancer), emphysema/air trapping (a biomarker for chronic obstructive pulmonary ...

Computed Tomography Imaging for Novel Therapies of Chronic Obstructive Pulmonary Disease.

Novel therapeutic options in chronic obstructive pulmonary disease (COPD) require delicate patient selection and thus demand for expert radiologists visually and quantitatively evaluating high-resolution computed tomography (CT) with additional functional acquisitions such as paired inspiratory-expiratory scans or dynamic airway CT. The differentiation between emphysema-dominant and airway-dominan...

Subtle motor signs in children with chronic traumatic brain injury.

To characterize subtle motor signs in children with moderate-severe traumatic brain injury (TBI) in the chronic phase of injury.

Procalcitonin and other markers to guide antibiotic use in chronic obstructive pulmonary disease exacerbations in the era of antimicrobial resistance.

This review summarizes the latest discoveries regarding the use of clinical indicators and biomarkers to guide antibiotic use in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD), and it analyzes the advantages and disadvantages of various indicators and markers.

NO FACE-DOWN POSITIONING SURGERY FOR THE REPAIR OF CHRONIC IDIOPATHIC MACULAR HOLES.

To report visual and anatomical outcomes after the repair of chronic idiopathic macular holes (MHs) with no face-down positioning.

Treatment strategies after acute exacerbations of chronic obstructive pulmonary disease: Impact on mortality.

Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is a common reason for presentation to emergency departments (ED), but the management of these episodes is often heterogeneous regardless of their potential impact on short-term adverse outcomes.

Type VI collagen promotes lung epithelial cell spreading and wound-closure.

Basement membrane (BM) is an essential part of the extracellular matrix (ECM) that plays a crucial role in mechanical support and signaling to epithelial cells during lung development, homeostasis and repair. Abnormal composition and remodeling of the lung ECM have been associated with developmental abnormalities observed in multiple pediatric and adult respiratory diseases. Collagen VI (COL6) is ...

An optimized protocol for the analysis of house dust mite (Dermatophagoides farinae)-induced neutrophil-dominant airway inflammation.

House dust mites (HDMs), Dermatophagoides sp., are one of the most widespread aeroallergens worldwide and cause various allergic diseases, including asthma. The pathophysiology of asthma has been intensively investigated using murine models of allergic airway inflammation induced by exposure to D. pteronyssinus. However, the pathogenic roles of D. farinae in the allergic airway inflammation remain...

Modulation of the unfolded protein response pathway as an antiviral approach in airway epithelial cells.

Rhinovirus (RV) infection is a major cause of cystic fibrosis (CF) lung morbidity with limited therapeutic options. Various diseases involving chronic inflammatory response and infection are associated with endoplasmic reticulum (ER) stress and subsequent activation of the unfolded protein response (UPR), an adaptive response to maintain cellular homeostasis. Recent evidence suggests impaired ER s...

Surgical Outcomes of Complex versus Simple Segmentectomy for Stage I Non-Small Cell Lung Cancer.

As segmentectomy becomes widely used for lung cancer treatment, "complex segmentectomy," which makes several, intricate intersegmental planes, remains controversial because of procedural complexity and risk of increased complications and incurability. Questions remain regarding mortality, morbidity, surgical margin, lymph nodes dissection, and postoperative pulmonary function. We evaluated operati...

The Asthma Controller Step-down Yardstick.

The role of the skin microbiome in atopic dermatitis.

TRPC channels mediated calcium entry is required for proliferation of human airway smooth muscle cells induced by nicotine-nAChR.

The present study was designed to explore the role of transient receptor potential canonical 3 (TRPC3) in nicotine-induced chronic obstructive pulmonary disease (COPD) and its underlying mechanism. In this study, the expression and localization of α5 nicotinic acetylcholine receptor (α5-nAchR) in lung tissues were determined by western blotting and immunohistochemistry. The quantitative real-tim...
