[A partnership between midwives and RPNs for the benefit of perinatal mental health].

Advanced practice nurses in psychiatry and mental health have the opportunity to become involved in perinatal health networks. By building a new form of partnership with maternal and child protection midwives, they can provide second-line skills for the mental health of vulnerable patients and participate in the quality and safety of care.

NR2A and NR2B receptor gene variations modify age at onset in Huntington disease.

N -Methyl-d-aspartate (NMDA) receptor-mediated excitotoxicity has been proposed to play a role in the pathogenesis of Huntington disease (HD), an autosomal dominantly inherited disorder associated with defined expansions in a stretch of perfect CAG repeats in the 5' part of the IT15 gene. The number of CAG repeat units is highly predictive for the age at onset (AO) in HD. However, AO is only modestly correlated with repeat length when the HD expansion range is in the high 30s or low 40s.
