Riboflavin status and its association with serum hs-CRP levels among clinical nurses with depression.

Objective: The objective of present study was to assess the relationship between the dietary intake and blood status of riboflavin and the prevalence of systemic inflammation among both depressed and nondepressed nurses.

Methods: This was a cross-sectional study on 98 female clinical nurses (45 depressed and 53 nondepressed subjects). Depression status was assessed using the Beck Depression Inventory.

Relationship between lactose digestion, gastrointestinal transit time and symptoms in lactose malabsorbers after dairy consumption.

Background: The relationship of symptoms with objective measurements, as well as some of the mechanisms involved in lactose tolerance after yoghurt consumption, remain unclear.

Methods: The trial had a double-blind design in which 22 lactose malabsorbers received 25 g daily lactose in fresh (living bacteria > 108 cfu/g) yoghurt or heated (< 102 cfu/g) yoghurt for 15 days, followed by a cross-over (15 days) after a wash-out period (14 days). The lactose digestion was determined by the breath H2 test, the gastric emptying (GE) with a 13C-acetate breath test and the revealed transit time (OCTT) by 15N-lactose-ureide test.
