Social media use is becoming common in medical practice. Although primarily used in this context to connect physicians, social media allows users share information, to create an online profile, to learn and keep knowledge up to date, to facilitate virtual attendance at medical conferences, and to measure impact within a field. However, shared content should be considered permanent and beyond the control of its author, and typical boundaries, such as the patient-physician interaction, become blurred, putting both parties at risk. The European Association of Urology brought together a committee of stakeholders to create guidance on the good practice and standards of use of social media. These encompass guidance about defining an online profile; managing accounts; protecting the reputations of yourself and your organization; protecting patient confidentiality; and creating honest, responsible content that reflects your standing as a physician and your membership within this profession.

Background

Idiopathic pulmonary fibrosis (IPF), a progressive disease with an unknown pathogenesis, may be due in part to an abnormal response to injurious stimuli by alveolar epithelial cells. Air pollution and particulate inhalation of matter evoke a wide variety of pulmonary and systemic inflammatory diseases. We therefore hypothesized that increased average ambient particulate matter (PM) concentrations would be associated with an accelerated rate of decline in FVC in IPF.

Methods

We identified a cohort of subjects seen at a single university referral center from 2007 to 2013. Average concentrations of particulate matter < 10 and < 2.5 μg/m³ (PM₁₀ and PM_2.5, respectively) were assigned to each patient based on geocoded residential addresses. A linear multivariable mixed-effects model determined the association between the rate of decline in FVC and average PM concentration, controlling for baseline FVC at first measurement and other covariates.

Results

One hundred thirty-five subjects were included in the final analysis after exclusion of subjects missing repeated spirometry measurements and those for whom exposure data were not available. There was a significant association between PM₁₀ levels and the rate of decline in FVC during the study period, with each μg/m³ increase in PM₁₀ corresponding with an additional 46 cc/y decline in FVC (P = .008).

Conclusions

Ambient air pollution, as measured by average PM₁₀ concentration, is associated with an increase in the rate of decline of FVC in IPF, suggesting a potential mechanistic role for air pollution in the progression of disease.
