High-dose cholecalciferol reduces parathyroid hormone in patients with early chronic kidney disease: a pilot, randomized, double-blind, placebo-controlled trial

submitted by: Vin_Tangpricha
Background: Vitamin D deficiency contributes to secondary hyperparathyroidism, which occurs early in chronic kidney disease (CKD). Objectives: We aimed to determine whether high-dose cholecalciferol supplementation for 1 y in early CKD is sufficient to maintain optimal vitamin D status (serum 25-hydroxyvitamin D [25(OH)D] concentration $30 ng/mL) and decrease serum parathyroid hormone (PTH). A secondary aim was to determine the effect of cholecalciferol on blood pressure and serum...

Pesticides and Herbicides: A Growing Concern (Webinar)

submitted by: Chrom Solutions
This webinar describes using suppressed ion chromatography--mass spectrometry (IC-MS/MS) for glyphosate (a widely used broad-spectrum herbicide) analysis with the result that required reporting limits can be achieved without time-consuming derivatization. In addition, a validated extraction method for weathered toxaphene (banned since 1990) and its degradation products in fish tissues using Accelerated Solvent Extraction is also discussed. Speakers: Diana Burdette (US EPA R4 SESD), Stuart...

Prepregnancy adherence to dietary patterns and lower risk of gestational diabetes mellitus

submitted by: dtobias
Abstract BACKGROUND: Previous studies observed inverse associations of adherence to the alternate Mediterranean (aMED), Dietary Approaches to Stop Hypertension (DASH), and alternate Healthy Eating Index (aHEI) dietary patterns with risk of type 2 diabetes; however, their associations with gestational diabetes mellitus (GDM) risk are unknown. OBJECTIVE: This study aimed to assess usual prepregnancy adherence to well-known dietary patterns and GDM risk. DESIGN: Our study included 21,376...
