Background Several studies in older people have shown that grip strength predicts all-cause mortality. The mechanisms are unclear. Muscle declines with age, accompanied by a loss of muscle mass and an increase fat, but the role body composition plays association between mortality has been little explored. We investigated relation strength, composition, cause-specific total 800 men women aged 65 over.

OBJECTIVE Proinsulin is a precursor of mature insulin and C-peptide. Higher circulating proinsulin levels are associated with impaired β-cell function, raised glucose levels, resistance, type 2 diabetes (T2D). Studies the processing pathway could provide new insights about T2D pathophysiology. RESEARCH DESIGN AND METHODS We have conducted meta-analysis genome-wide association tests ∼2.5 million genotyped or imputed single nucleotide polymorphisms (SNPs) fasting in 10,701 nondiabetic adults...
