Multicenter Study
Clinical significance of cold-inducible RNA-binding protein in idiopathic pulmonary fibrosis.
Idiopathic pulmonary fibrosis (IPF) is associated with a poor prognosis with variable clinical course. Early identification of patients at high risk for disease progression and death would lead to early therapeutic intervention and thereby improvement of outcomes. Cold-inducible RNA-binding protein (CIRBP) is produced in response to cellular stresses, which is implicated in multiple biological processes, including cell survival and proliferation. ⋯ This study successfully validated that serum CIRBP level was an independent predictor of 1-year disease progression and all-cause mortality in IPF. CIRBP is a promising biomarker that can help identify high-risk patients with IPF, especially in the early stage.

Previous studies reported a strong association between sleepiness-related symptoms and comorbidities with poor cardiovascular outcomes among patients with moderate to severe OSA (msOSA). However, the validation of these associations in the Hispanic population from South America and the ability to predict incident cardiovascular disease remain unclear. ⋯ Among patients with msOSA, a symptom-based approach can validate different OSA patient subtypes, and those with excessive sleepiness have an increased risk of incident cardiovascular mortality in the Hispanic population from South America.

Hospitalization Risk for Medicare Beneficiaries With Nontuberculous Mycobacterial Pulmonary Disease.
Nontuberculous mycobacterial pulmonary disease (NTM-PD) is an uncommon mycobacterial infection characterized by worsening lung function and increased health care resource utilization; however, the overall risk for hospitalization among patients with NTM-PD remains unclear. ⋯ Patients with NTM-PD were significantly more likely to be hospitalized, had greater annualized hospitalization rates, and had shorter time to hospitalization than age- and sex-matched control subjects without NTM-PD. These findings highlight the significantly increased burden of hospitalizations among patients with NTM-PD.

A 30-year-old man with a history of childhood asthma, a 15-pack-year smoking history, and methamphetamine abuse was intubated and started on mechanical ventilation because of acute hypoxic respiratory failure after experiencing progressive dyspnea and a nonproductive cough over the previous year. During the previous 3 months, he had multiple clinic visits, with chest radiographs showing diffuse, bilateral, reticulonodular opacities and small bilateral pleural effusions and was treated for community-acquired pneumonia. ⋯ Physical examination on admission showed diffuse fine crackles bilaterally on lung auscultation. Admission laboratory test results were unremarkable.

A 17-year-old previously healthy Taiwanese girl presented with syncope on a background of 1 month of weakness, polyarthritis, and heliotrope rash. Her presentation and investigations, which included an elevated creatine phosphokinase level and diffuse myositis on lower limb MRI, were consistent with juvenile dermatomyositis (JDM).
