Purpose Of Review: This review summarizes recent research on pneumoconiosis in coal workers following the identification of the resurgence of this disease among US coal miners in the early 2000s. We describe the impact of this research and how this has led to increased public attention, benefitting affected miners.
Recent Findings: The latest research shows that the prevalence of pneumoconiosis, including progressive massive fibrosis, continues to increase, especially in central Appalachia. Contributing factors may include mining of thin coal seams or cutting rock to access coal, which may expose miners to coal mine dust with a higher content of silica and silicates than in the past. The impact of recently implemented changes, such as the reduced occupational exposure limit for respirable coal mine dust and the introduction of continuous personal dust monitors, will likely take years to appropriately evaluate.

Pneumoconiosis, caused by inhaling mineral dust, remains a significant occupational disease, despite a declining incidence. Coal workers' pneumoconiosis (CWP), a common subtype, varies in presentation from simple to complicated forms. Differential diagnosis is crucial, especially when CWP manifests as lung masses mimicking malignancy.

Pulmonary hypertension is a progressive disease associated with remodeling of the pulmonary vasculature. Excessive proliferation and migration of pulmonary artery smooth muscle cells (PASMCs) play important roles in nicotine-induced vascular injury. Connexin 43 (Cx43) is involved in intracellular communication and regulation of the pulmonary vasculature.

Introduction: Previous studies suggest respirable crystalline silica (RCS) is an important driver of resurgent pneumoconiosis among US coal miners. Although greater attention has been focused on dust exposures in underground coal miners, surface miners are also at risk of severe disease. This study explores RCS exposure in this population.

The ongoing resurgence of severe Coal Workers' Pneumoconiosis in the US has been linked to overexposure to respirable crystalline silica (RCS, which is predominantly present as quartz and regulated as such). Capabilities that enable more frequent RCS monitoring are highly sought. Recent developments include field-based quartz analysis of traditional filter samples-collected on polyvinyl chloride (PVC) filters-using portable Fourier Transform Infrared spectroscopy (FTIR).

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.
