Community perceptions and mental burden among (former) residents at Europe’s largest lignite mine in Western Germany: a cross-sectional study

open access: yesScientific Reports
During the many years that coal has been used for energy production, most studies have focused on the global environmental impacts such as climate change or, when addressing health, rather on conditions of open pit coal miners.

Influence of vibrations on structures [PDF]

open access: yes, 2018
One type of occasional structural load is a seismic load. Earthquakes and blasts are typical sources of vibrations, but vibration generated during urban tunnel construction can represent a significant problem.

Cancer pattern in Bhutan (2014–2022): Findings from population‐based cancer registry—A pathway to monitor cancer control activities

open access: yesInternational Journal of Cancer, EarlyView.
What's New? The establishment in 2014 of the population‐based cancer registry (PBCR) of Bhutan created new opportunities for understanding national cancer trends, which previously were anticipated from data in neighbouring countries. This study presents the first nine‐year summary of cancer patterns in Bhutan, derived from PBCR data. From 2014 to 2022,

Systemic Immunosuppression to Reduce Surgical Intervention in ANCA‐Negative Subglottic Stenosis

open access: yesThe Laryngoscope, EarlyView.
Idiopathic subglottic stenosis (iSGS) typically follows an indolent course managed with surgical dilatation, though a subset demonstrates aggressive, recurrent disease. In this retrospective cohort study, systemic immunosuppression significantly prolonged inter‐dilation intervals in both granulomatosis with polyangiitis‐associated SGS and an “atypical”
