Pregnancy complications such as pre-eclampsia and intrauterine growth restriction are associated with abnormal placental cell (cytotrophoblast; CT) proliferation and apoptosis. The mechanisms regulating these events are unclear however altered levels of IGFs have also been reported in these conditions. Using an explant model of human first trimester placenta we have shown that both IGF-I and –II act through IGF1R mediated signalling pathways to enhance CT proliferation, d...

IGF-I and -II influence cytotrophoblast proliferation by activating the type-I IGF receptor (IGF1R) in first trimester human placenta. Ligand access to receptors is regulated by IGF binding proteins (IGFBPs) 1-6. In humans, the most abundant IGFBPs at the maternal-fetal interface are IGFBP-1 and IGFBP-3; we hypothesised that these IGFBPs function to regulate the effects of IGFs in the placenta and used our placental explant model, in which proliferation and differentiation are...

Aim: To compare inpatient length of stay (LOS) and mortality of diabetic and non-diabetic patients aged ≧65 years admitted in a single UK hospital with fractured proximal femur.Methods: Patients with a fractured proximal femur at University Hospital of Birmingham (2007–2010) were identified from administrative data with ICD 10 discharge diagnostic codes S720, S721 and S722 as the primary diagnosis. A discharge diagnostic code for diabetes or ...

Abnormal fetal growth remains a problem in pregnancies, complicated by diabetes and is associated with increased maternal and offspring mortality and morbidity. Insulin-like growth factors (IGFs) are important regulators of fetal growth. Their effects are controlled by binding proteins (IGFBPs). IGFBP-1 is particularly important in pregnancy. Phosphorylated IGFBP-1 (pIGFBP-1) has a high affinity for IGF-I and inhibits IGF-I actions, whereas de-phosphhorylated IGFBP-1 has a low...
