Effect of High- versus Low-Fat Meal on Serum 25-Hydroxyvitamin D Levels after a Single Oral Dose of Vitamin D: A Single-Blind, Parallel, Randomized Trial.

Background/Aims. Vitamin D(3) is liposoluble, so dietary fat could increase its oral absorption. Our aim was to compare serum 25-hydroxyvitamin D [25(OH)D] after the oral intake of cholecalciferol with a high- or low-fat meal.

Pneumonia in the first 2 years of life, and asthma in preschool-age children.

Background: The relationship between viral bronchiolitis in early infancy and subsequent wheezing and asthma has been well established. The aim of the present cross-sectional study was to test the hypothesis that pneumonia severe enough to require hospitalization during the first 2 years of life could also be associated with asthma or asthma-like symptoms in pre-school children.

Methods: Structured interviews were conducted with parents of children who were classified as exposed (n= 36) or non-exposed (n= 84), based on whether they were hospitalized with radiologically confirmed pneumonia during the first 2 years of life.
