Long-term macrolide therapy has been shown to provide benefit to those with a range of chronic respiratory conditions. However, concerns remain about the impact of macrolide exposure on the carriage and abundance of antibiotic resistance genes within the oropharynx. The potential for onward transmission of resistance from macrolide recipients to their close contacts also is poorly understood. ⋯ Although levels of erm(B) were higher in those receiving long-term macrolide therapy and evidence of gene cocarriage with close contacts was found, no evidence was found that macrolide use increased the onward transmission risk to their close contacts. This study therefore addresses concerns that long-term macrolide therapy could promote the dissemination of transmissible macrolide resistance.

Pulmonary hypertension (PH) is a common complication of interstitial lung disease (ILD) and is associated with worse outcomes and increased mortality. Evaluation of PH is recommended in lung transplant candidates, but there are currently no standardized screening approaches. Trials have identified therapies that are effective in this setting, providing another rationale to routinely screen patients with ILD for PH. ⋯ Many patients with ILD may benefit from early evaluation of PH now that an approved therapy is available. Protocols to evaluate patients with ILD often overlap with evaluations for pulmonary hypertension-interstitial lung disease and can be used to assess the risk of PH. Because standardized approaches are lacking, this consensus statement is intended to aid physicians in the identification of patients with ILD and possible PH, and provide guidance for timely right heart catheterization.

A 27-year-old accountant came to the ED with difficulty walking and progressive weakness of both lower limbs for 4 days' duration. He did not report a history of trauma or fall. He demonstrated no vertigo, headache, neck or back pain, disturbed vision, loss of weight, or weakness in upper limbs. ⋯ He had maintained an oxygen saturation of 98% to 99% as measured on pulse oximetry. He had not received any treatment at that time. His symptoms had lasted for 7 days, and he remained asymptomatic up to the current presentation with paraparesis.

A 63-year-old man, who was a current smoker with a 10-pack-year history, was referred to our hospital for nonmassive hemoptysis for a month, and a large mass was observed in the right upper lobe on chest radiography. He lost 3 kg of weight within a few months. He did not have fever, breathlessness, or night sweats, and he denied a history of liver disease, alcohol consumption, or contact with a person infected with TB. He was previously healthy and was not currently taking any medication.
