Use of the Robson Ten Group Classification System to categorise operative vaginal delivery.

Background: Operative vaginal delivery (OVD), either vacuum or forceps, can be used to expedite vaginal delivery. While rates of OVD have been reducing worldwide, rates in Ireland remain high. The Robson Ten Group Classification System (TGCS) was originally created to compare rates of caesarean delivery between healthcare units, although no similar system exists for the analysis of OVD.

Noradrenaline acting on astrocytic β₂-adrenoceptors induces neurite outgrowth in primary cortical neurons.

The neurotransmitter noradrenaline (NA) has anti-inflammatory properties and promotes expression of neurotrophic factors in the central nervous system (CNS) via activation of glial adrenoceptors. Here we examined the ability of conditioned media (CM) from NA-treated glial cells to impact upon neuronal complexity. Primary rat cortical neurons were treated either directly with NA (1-10 μM), or treated with CM from NA-stimulated primary mixed glial cells.
