Analysis of comorbidity in rheumatoid arthritis-associated interstitial lung disease: a nested case-cohort study.

Objectives: To describe comorbid conditions in patients with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) and to analyze factors associated with multimorbidity.

Methods: Nested case-cohort study of 2 prospective cohorts: one with RA-ILD (cases) and another with RA but not ILD (controls). The cohorts were matched for age, sex, and time since diagnosis.

Risk of progression to Alzheimer's disease for different neuropsychological Mild Cognitive Impairment subtypes: A hierarchical meta-analysis of longitudinal studies.

Mild Cognitive Impairment (MCI) is a heterogeneous condition between normal aging and dementia. Upon neuropsychological testing, MCI can be divided into 4 groups: single-domain amnestic MCI (sd-aMCI), multiple-domain amnestic MCI (md-aMCI), single- and multiple-domain nonamnestic MCI (sd-naMCI, md-naMCI). Some controversy exists about whether the risk of progression to Alzheimer's disease (risk-AD) is increased in all MCI subtypes.
