This review explores the multifaceted roles of microbial dysbiosis in RA, emphasizing its impact on immune cell modulation, autoantibody production, gut barrier integrity, and joint inflammation. Animal models reveal how genetic predisposition and environmental factors interact with specific microbial taxa to influence disease susceptibility.

Mapping organism-wide single cell mRNA expression linked to extracellular vesicle biogenesis, secretion and cargo.

Extracellular vesicles (EVs) are functional lipid-bound nanoparticles trafficked between cells and found in every biofluid. It is widely claimed that EVs can be secreted by every cell, but the quantity and composition of these EVs can differ greatly among cell types and tissues. Defining this heterogeneity has broad implications for EV-based communication in health and disease.

Protocol for a systematic review and individual participant data meta-analysis for risk factors for lung cancer in individuals with lung nodules identified by low-dose CT screening.

Background: Worldwide, lung cancer (LC) is the second most frequent cancer and the leading cause of cancer related mortality. Low-dose CT (LDCT) screening reduced LC mortality by 20-24% in randomised trials of high-risk populations. A significant proportion of those screened have nodules detected that are found to be benign.

Adherence to tuberculosis (TB) treatment in high compared to low TB burden countries: study protocol for a systematic review and meta-analysis with a qualitative meta-synthesis of themes.

Introduction: Non-adherence to tuberculosis (TB) treatment poses a significant challenge to effective TB management globally and is a major contributor to the emergence of multidrug-resistant TB. Although adherence to TB treatment has been widely studied, a comprehensive evaluation of the comparative levels of adherence in high- versus low-TB burden settings remains lacking. The objective of this systematic review and meta-analysis is to assess the levels of adherence to TB treatment in high-TB burden countries compared to low-burden countries.

Impact of microgeography on communication dynamics in a healthcare environment.

Background: For growing healthcare organisations, anchored resources-assets that are not easily movable-may complicate expansion and distort workflow patterns. We examine work patterns at a radiation oncology department of a major Canadian hospital. As this department doubled its size, healthcare providers remained bound to treatment planning rooms and radiation machines at the original site.

The Role of Imaging in Pulmonary Vascular Disease: The Clinician's Perspective.

Pulmonary vascular diseases, particularly when accompanied by pulmonary hypertension, are complex disorders often requiring multimodal imaging for diagnosis and monitoring. Echocardiography is the primary screening tool for pulmonary hypertension, while cardiac MR imaging (CMR) is used for more detailed characterization and risk stratification in right ventricular failure. Chest computed tomography (CT) is used to detect vascular anomalies and parenchymal lung diseases.

Pulmonary Vascular Interventions.

Endovascular intervention is a safe, effective treatment modality in the management of diverse pulmonary vascular pathologies, including acute or chronic thromboembolic disease, pulmonary arteriovenous malformations (pAVMs), pulmonary artery or bronchial artery hemorrhage, and foreign body retrieval. This article reviews indications, contraindications, techniques, and outcomes in endovascular management of common pulmonary vascular pathologies, with the goal of improving operator familiarity and facility with these procedures.

Role of Cardiovascular MR Imaging and MR Angiography in Patients with Pulmonary Vascular Disease.

Cardiac MR imaging and pulmonary MR angiography (MRA) are important clinical tools for the assessment of pulmonary vascular diseases. There are evolving noncontrast and contrast-enhanced techniques to evaluate pulmonary vasculature. Pulmonary MRA is a feasible imaging alternative to CTA in pulmonary embolism detection.

Neonatal and Pediatric Pulmonary Vascular Disease.

Pediatric patients are affected by a wide variety of pulmonary vascular diseases ranging from congenital anomalies diagnosed at birth to acquired diseases that present later in childhood and into adolescence. While some pulmonary vascular diseases present similarly to those seen in adults, other forms are unique to children. Knowledge of the characteristic imaging features of these diseases is essential to facilitate prompt diagnosis and guide clinical management.

Congenital Pulmonary Vascular Anomalies and Disease.

Congenital pulmonary vascular disease is a daunting and diverse topic spanning both pulmonary arterial and venous anomalies. Given advancements in treatment, patients with congenital anomalies have longer life expectancies into adulthood and practicing radiologists are bound to come across these patients during their daily practice. Additionally, many anomalies are discovered incidentally on imaging, yet may still have implications for patient care.

Imaging of Pulmonary Vasculitis.

This review will describe various disease processes resulting in pulmonary vasculitis. The clinical and imaging findings in these diseases often overlap with diffuse alveolar hemorrhage secondary to pulmonary capillaritis, a common manifestation in many of these diseases. A multidisciplinary approach is important for the correct diagnosis of these diseases, and this review will highlight the important imaging findings that radiologists need to be aware of to aid in this diagnostic process.

Imaging of Chronic Thromboembolic Pulmonary Hypertension.

Chronic thromboembolic pulmonary hypertension (CTEPH) is pulmonary hypertension secondary to chronic obstruction of pulmonary arteries by organized thromboemboli. Echocardiography and Echocardiography and ventilation/perfusion (V/Q) scan are the initial screening examinations for CTEPH; the diagnosis is often missed on computed tomography (CT). Imaging findings of chronic thromboembolic pulmonary disease overlap with those of acute pulmonary embolism, and radiologists should evaluate for the presence of concurrent chronic disease in all cases of acute pulmonary embolism detected on CT pulmonary angiography.

Imaging of Acute Pulmonary Embolism: An Update.

Imaging is essential in the evaluation and management of acute pulmonary embolism. Advances in multi-energy CT including dual-energy CT and photon-counting CT have allowed faster scans with lower radiation dose and optimal quality.
