[Sensitivity and specificity of metabolic syndrome criteria for insulin resistance diagnosis in Spanish population].

Background And Objective: Metabolic syndrome (MS) is an abdominal obesity and insulin resistance (IR)-related syndrome associated with a high cardiovascular risk. Recently, the International Diabetes Federation (IDF) has proposed a modification of the Adult Treatment Panel III (ATP III) diagnostic criteria. However, the sensitivity of these new criteria has not been established.

Ultrasonography for the evaluation of visceral fat and the metabolic syndrome.

Association between abdominal obesity and cardiovascular disease has been related with visceral adiposity, through the predisposition of developing type 2 diabetes mellitus and metabolic syndrome (MS). Sonography is a simple and reliable method to measure both subcutaneous and visceral fat. To analyze the relationship of anthropometric measurements with abdominal adiposity measured by sonography and to analyze the utility of sonography in the prediction of insulin resistance (IR) and the other components of MS.

[Continuous enteral nutrition versus single bolus: effects on urine C peptide and nitrogen balance].

Background And Objective: Our study was designed to assess the impact on nitrogen and glucose metabolism when it is administered either as discontinuous or as continuous infusion.

Patients And Method: We assessed the nutritional efficacy (nitrogen balance) and hyperinsulinism risk (urine C peptide excretion) of enteral nutrition in 23 patients hospitalized because of acute stroke.

Results: The feeding tolerance of our enteral nutrition protocol (nasoenteric catheter) was full in every patient.

Insulin-like growth factors in childhood-onset Gaucher disease.

There is a high prevalence of growth retardation in children with type 1 Gaucher disease. The cause of this poor growth is not yet known; however, studies have shown acceleration of growth with enzyme replacement therapy (ERT). IGF are recognized as important determinants of somatic growth.
