Multicenter Study
Clinical presentation, course, and prognosis of patients with mixed connective tissue disease: A multicenter retrospective cohort.
The objective of this study is to better characterize the features and outcomes of a large population of patients with mixed connective tissue disease (MCTD). ⋯ This study shows that MCTD is a distinct entity that can be classified using either Kasukawa or Sharp criteria, and that only 25.8% of patients progress to a dCTD during follow-up.

Multicenter Study
Prevalence and prognostic value of electrocardiographic abnormalities in hypokalemia: A multicenter cohort study.
Hypokalemia is common in hospitalized patients and associated with ECG abnormalities. The prevalence and prognostic value of ECG abnormalities in hypokalemic patients are, however, not well established. ⋯ ECG abnormalities were common in hypokalemic patients, but they are poor prognostic markers for short-term adverse events under the current standard of care.
