We previously reported a novel peptide, Hippocampal Cholinergic Neurostimulating Peptide (HCNP), which induces acetylcholine synthesis by increasing the amount of choline acetyltransferase (ChAT) in medial septal nuclei. The HCNP precursor protein (HCNP-pp), composed of 186 amino acids, is an inhibitory factor of the c-Raf/MEK cascade and may be involved in fetal rat brain development via the inhibition of phosphorylation of Erk. To clarify the involvement of HCNP in hippocampal cholinergic circuitry, we previously generated HCNP-pp transgenic (HCNP-pp Tg) mice using the promoter of the α subunit of Ca(2+) calmodulin-dependent protein kinase II (CaMKIIα). These mice showed increased levels of ChAT in medial septal nuclei at 12 weeks of age, and the phenotype of depressive mood at 30 weeks of age. Here, through proteomic analysis we investigated the alteration of protein expression in the hippocampus of HCNP-pp Tg mice compared with wild-type littermate mice. We demonstrate that the activation of collapsin response mediator protein-2 (CRMP-2) is increased in the transgenic mice at 12 weeks of age when compared with wild-type littermate mice.

Early developmental trajectories of the impaired hand in infants with unilateral cerebral palsy.
Dev Med Child Neurol
January 2025
Queensland Cerebral Palsy and Rehabilitation Research Centre, Child Health Research Centre, Faculty of Medicine, The University of Queensland, Brisbane, Australia.
Aim: To identify developmental trajectories of impaired hand function in infants aged 3 to 15 months with unilateral cerebral palsy (CP).
Method: Sixty-three infants (37 male; median gestational age 37 weeks [interquartile range 30-39.1 weeks]) recruited as part of a randomized trial with a confirmed diagnosis of unilateral CP were included.
Combined first-trimester screening for preterm small-for-gestational-age infants: Australian multicenter clinical feasibility study.
Ultrasound Obstet Gynecol
January 2025
Discipline of Obstetrics, Gynaecology and Neonatology, Faculty of Medicine and Health, University of Sydney, Sydney, NSW, Australia.
Objective: To assess the performance of the Fetal Medicine Foundation (FMF) first-trimester competing-risks screening model for small-for-gestational-age (SGA) fetuses requiring delivery at < 37 weeks' gestation, in a large cohort of women receiving maternity care in Australia.
Methods: This was a retrospective analysis of prospectively collected data from a cohort of women attending one of two private multicenter fetal medicine practices for first-trimester screening for preterm pre-eclampsia (PE), defined as PE requiring delivery before 37 weeks' gestation. Risk for preterm SGA, defined as SGA requiring delivery before 37 weeks, was calculated but was not disclosed to the patient or referring physician.
[Assessment of corticosteroid use as a marker of quality-of-care in the management of inflammatory bowel disease].

Introduction: Despite advancements in therapeutic strategies, corticosteroids continue to play a role in inducing remission in Inflammatory Bowel Disease (IBD). Unfortunately, these drugs are often misused.
Objectives: To assess the dose and duration of corticosteroid therapy,and the subsequent change in treatment among patients with IBD.
Prediction of pre-eclampsia using maternal hemodynamic parameters at 12 + 0 to 15 + 6 weeks.
Ultrasound Obstet Gynecol

Department of Obstetrics and Gynaecology, Prince of Wales Hospital, The Chinese University of Hong Kong, Hong Kong, SAR, China.
Objectives: To compare the maternal hemodynamic profile at 12 + 0 to 15 + 6 weeks' gestation in women who subsequently developed pre-eclampsia (PE) and those who did not, and to assess the screening performance of maternal hemodynamic parameters for PE in combination with the Fetal Medicine Foundation (FMF) triple test, including maternal factors (MF), mean arterial pressure (MAP), uterine artery pulsatility index and placental growth factor.
Methods: This was a prospective case-control study involving Chinese women with a singleton pregnancy who underwent preterm PE screening at 11 + 0 to 13 + 6 weeks' gestation using the FMF triple test, between February 2020 and February 2023. Women identified as being at high risk (≥ 1:100) for preterm PE by the FMF triple test were matched 1:1 with women identified as low risk (< 1:100) for maternal age ± 3 years, maternal weight ± 5 kg and date of screening ± 14 days.
Development and validation of a risk prediction model for gestational diabetes mellitus in women of advanced maternal age during the first trimester.

With the global rise in advanced maternal age (AMA) pregnancies, the risk of gestational diabetes mellitus (GDM) increases. However, few GDM prediction models are tailored for AMA women. This study aims to develop a practical risk prediction model for GDM in AMA women.
