Randomized Controlled TrialIntravenous intralipid-induced blood pressure elevation and endothelial dysfunction in obese African-Americans with type 2 diabetes.
Increased free fatty acids (FFAs) are leading candidates in the pathogenesis of insulin resistance and hypertension in obese subjects. We evaluated the effect of sustained elevations of FFA on blood pressure, endothelial function, insulin secretion, inflammatory markers, and renin-angiotensin system. ⋯ Increased FFA levels result in a rapid and sustained elevation in blood pressure, impaired endothelial function, and increased inflammatory markers in obese subjects with type 2 diabetes. The model of FFA-induced hypertension may be useful in examining disease mechanisms associated with the development of hypertension in obese subjects.

Randomized Controlled TrialThe antiresorptive effects of a single dose of zoledronate persist for two years: a randomized, placebo-controlled trial in osteopenic postmenopausal women.
Annual iv administration of 5 mg zoledronate decreases fracture risk. The optimal dosing interval of 5 mg zoledronate is not known. ⋯ The antiresorptive effects of a single 5-mg dose of zoledronate are sustained for at least 2 yr. The magnitudes of the effects on markers of bone turnover and bone mineral density are comparable at 12 and 24 months. Administration of zoledronate at intervals of up to 2 yr may be associated with antifracture efficacy; clinical trials to investigate this possibility are justified.

Guidelines for the management of asymptomatic primary hyperparathyroidism: summary statement from the third international workshop.
Asymptomatic primary hyperparathyroidism (PHPT) is a common clinical problem. The purpose of this report is to guide the use of diagnostics and management for this condition in clinical practice. ⋯ Consensus was achieved by a group meeting. Statements were prepared and reviewed by all authors who represented the Planning Committee and the participating professional societies.
