Living with children who have coeliac disease: a parental perspective.

Background: This study explores how a child's coeliac disease (CD) influences the daily life of families because such knowledge can enhance the understanding of how to support family adjustment to a gluten-free diet (GFD).

Methods: We used an interpretative phenomenological approach, interviewing 20 parents of 14 children diagnosed with CD about their individual thoughts and beliefs.

Results: Once parents know, especially when their children are young, they seem to have the capacity to rapidly adapt to GFD, mainly because they notice how quickly their children recover.

Increased uncoupling protein 3 content does not affect mitochondrial function in human skeletal muscle in vivo.

Phosphocreatine (PCr) resynthesis rate following intense anoxic contraction can be used as a sensitive index of in vivo mitochondrial function. We examined the effect of a diet-induced increase in uncoupling protein 3 (UCP3) expression on postexercise PCr resynthesis in skeletal muscle. Nine healthy male volunteers undertook 20 one-legged maximal voluntary contractions with limb blood flow occluded to deplete muscle PCr stores.

Creatine supplementation has no effect on human muscle protein turnover at rest in the postabsorptive or fed states.

Dietary creatine supplementation is associated with increases in muscle mass, but the mechanism is unknown. We tested the hypothesis that creatine supplementation enhanced myofibrillar protein synthesis (MPS) and diminished muscle protein breakdown (MPB) in the fed state. Six healthy men (26 +/- 7 yr, body mass index 22 +/- 4 kg/m(2)) were studied twice, 2-4 wk apart, before and after ingestion of creatine (21 g/day, 5 days).

The role of phosphorylcreatine and creatine in the regulation of mitochondrial respiration in human skeletal muscle.

1. The role of phosphorylcreatine (PCr) and creatine (Cr) in the regulation of mitochondrial respiration was investigated in permeabilised fibre bundles prepared from human vastus lateralis muscle. 2.

Phosphocreatine degradation in type I and type II muscle fibres during submaximal exercise in man: effect of carbohydrate ingestion.

1. The aim of this study was to examine the effect of carbohydrate (CHO) ingestion on changes in ATP and phosphocreatine (PCr) concentrations in different muscle fibre types during prolonged running and relate those changes to the degree of glycogen depletion. 2.
