BACKGROUND Previous studies on dietary magnesium and risk of ischemic heart disease (IHD) have yielded inconsistent results, in part because of a lack of direct measures of actual magnesium uptake. Urinary excretion of magnesium, an indicator of dietary magnesium uptake, might provide more consistent results. OBJECTIVE The objective was to investigate(More)
AIMS/HYPOTHESIS To determine whether 6 weeks of daily, moderate alcohol consumption increases expression of the gene encoding adiponectin (ADIPOQ) and plasma levels of the protein, and improves insulin sensitivity in postmenopausal women. METHODS In a randomised, open-label, crossover trial conducted in the Netherlands, 36 apparently healthy(More)
Observational studies on dietary or circulating magnesium and risk of hypertension have reported weak-to-modest inverse associations, but have lacked measures of actual dietary uptake. Urinary magnesium excretion, an indicator of intestinal magnesium absorption, may provide a better insight in this association. We examined 5511 participants aged 28 to 75(More)
OBJECTIVE Lower concentrations of adiponectin have been linked to subsequent risk of coronary heart disease in healthy individuals. Whether similar relationships exist for the development of systemic atherosclerosis, such as peripheral artery disease (PAD), is uncertain. We investigated the association between total adiponectin and risk of lower extremity(More)
CONTEXT Vitamin D deficiency is common in renal transplant recipients (RTR). The long-term implications of vitamin D deficiency in RTR remain unclear. OBJECTIVE We investigated whether 25(OH) or 1,25(OH)2 vitamin D levels are associated with mortality, renal function decline, and graft failure in stable RTR. DESIGN Observational study with longitudinal(More)
Moderate alcohol consumption has various effects on immune and inflammatory processes, which could accumulatively modulate chronic disease risk. So far, no comprehensive, integrative profiling has been performed to investigate the effects of longer-term alcohol consumption. Therefore, we studied the effects of alcohol consumption on gene expression patterns(More)
OBJECTIVES The goal of this study was to examine the prospective association between oxidation-specific biomarkers, primarily oxidized phospholipids (OxPL) on apolipoprotein B-100-containing lipoproteins (OxPL/apoB) and lipoprotein (a) [Lp(a)], and risk of peripheral artery disease (PAD). We examined, as secondary analyses, indirect measures of oxidized(More)
Previous observational studies on the vascular effects of vitamin D have predominantly relied on measurement of its inactive precursor, 25-hydroxyvitamin D, whereas the active metabolite 1,25-dihydroxyvitamin D may be of more physiological relevance. We prospectively studied the associations of 1,25-dihydroxyvitamin D and 25-hydroxyvitamin D with(More)
Moderate alcohol consumption is associated with increased concentrations of adiponectin. Whether this is the case for both total and high-molecular-weight (HMW) adiponectin is uncertain. Furthermore, the rate at which this increase occurs is unclear. Therefore, we examined the effect of moderate alcohol consumption on total and HMW adiponectin. In a(More)
OBJECTIVE Few studies have examined the roles of homocysteine and related nutrients in the development of peripheral artery disease (PAD). We examined the associations between plasma homocysteine, dietary B vitamins, betaine, choline, and supplemental folic acid use and incidence of PAD. METHODS We used two cohort studies of 72,348 women in the Nurses'(More)
