A paradoxical association between cholesterol level and clinical outcome has been suggested, yet never previously established, in patients with chronic obstructive pulmonary disease (COPD). ⋯ Low cholesterol levels are significantly associated with increased mortality after AECOPD. Nonetheless, as statin treatment was associated with reduced mortality over the entire range of cholesterol levels, its use should be considered in all COPD patients.

Cardiovascular disease is the leading cause of death in chronic kidney disease. Extracellular matrix remodeling is implicated in atherosclerosis development. This study investigated the effects and possible mechanism of type I collagen expression on radial artery elasticity in patients with end-stage renal disease (ESRD). ⋯ Type I collagen expression is an essential factor for radial artery elasticity dysfunction in patients with ESRD. Uremic toxins apparently induced a phenotypic transition of the rat aortic VSMCs, leading to increased type I collagen secretion and subsequent extracellular matrix remodeling.
