Influence of initial clinical suspicion on the diagnostic yield of laboratory enzymatic testing in lysosomal storage disorders. Experience from a multispecialty hospital.

Lysosomal storage disorders (LSD) are a group of inherited metabolic diseases mainly caused by a deficiency of lysosomal hydrolases, resulting in a gradual accumulation of non-degraded substrates in different tissues causing the characteristic clinical manifestations of such disorders. Confirmatory tests of suspected LSD individuals include enzymatic and genetic testing. A well-oriented clinical suspicion can improve the cost-effectiveness of confirmatory tests and reduce the time expended to achieve the diagnosis.

Angiogenic Factors and Long-Term Cardiovascular Risk in Women That Developed Preeclampsia During Pregnancy.

Preeclampsia is caused by placental impairment with increased expression of sFlt-1 (soluble fms-like tyrosine kinase 1) and decreased PlGF (placental growth factor); it has been associated with cardiovascular morbidity and mortality later in life, but the underlying mechanism remains unknown. The aim of this study was to determine whether sFlt-1 and PlGF levels during preeclampsia are associated to long-term cardiovascular risk. We prospectively recruited 43 women with previous preeclampsia and 21 controls with uncomplicated pregnancies.

Premature placental aging in term small-for-gestational-age and growth-restricted fetuses.

Objective: To perform a comprehensive assessment of the placental aging process in small term fetuses classified as being small-for-gestational age (SGA) or having fetal growth restriction (FGR) through analysis of senescence and apoptosis markers.
