We, my Associate Editors, and I have done our best to usher in the new millennium, while remaining true stewards of this v...

INTRODUCTION Although previous studies found that cigarette smoking is associated with risk of rheumatoid arthritis (RA), the dose-response relationship remains unclear. This meta-analysis quantitatively summarizes accumulated evidence regarding the association of lifelong exposure to cigarette smoking assessed as pack-years with the risk of RA. METHODS Relevant studies were identified by a s...

This study characterized the determinants of carotid atherosclerosis in a large contemporary sample of current smokers. Associations between risk factors, carotid intima-media thickness (CIMT), and carotid plaque presence were determined by multivariable regression. Participants included 1504 current smokers (58% female) who were a median (interquartile range) of 44.7 (38-53) years old and smok...
