Prediabetes and impaired lung function in asymptomatic adults.

Diabetes and metabolic syndrome are associated with impaired lung function. However, it is unknown whether this is also true in prediabetes. In a cross-sectional study of 1237 asymptomatic adults, we found that diabetes and prediabetes were both significantly associated with low vital capacity, even after adjustment for relevant confounding factors.

Coffee consumption and cystatin-C-based estimated glomerular filtration rates in healthy young adults: results of a clinical trial.

Recently it has been reported that the estimated glomerular filtration rate (eGFR) is higher in habitual coffee consumers than in noncoffee consumers. However, the causality remains unclear. Therefore, we conducted a clinical trial to investigate the effects of coffee consumption on kidney function.
