Perinatal liver inflammation can have life-threatening consequences, particularly in infants and young children. An example of a hepatic inflammatory disease during infancy is biliary atresia (BA), an obliterative cholangiopathy that rapidly progresses to hepatic fibrosis and liver failure. The aggressive nature of BA in neonates compared to the pathogenesis of inflammatory liver diseases in adults, suggests that the mechanisms responsible for restoring tissue homeostasis following inflammation are impaired in affected infants. This article reviews our recent findings demonstrating that the relative abundance of Ly6c non-classical monocytes promotes resolution of perinatal liver injury in a murine model of perinatal hepatic inflammation. Our research also identifies a potential co-regulatory role between neutrophils and non-classical monocytes. Further work is needed to understand how neutrophils regulate other myeloid populations during perinatal liver inflammation. Elucidating the mechanisms that govern perinatal liver injury and repair may lead to the development of immune-directed therapies that can be used to mitigate the devastating effects of diseases like BA.

Transamniotic Delivery of Hematopoietic Stem Cells Genetically Modified to Carry a Human Hemoglobin Subunit Beta Gene (HBB) in a Healthy Rodent Model.

Background: We sought to determine whether transamniotic stem cell therapy (TRASCET) could be a viable alternative for the fetal administration of genetically modified hematopoietic stem cells (HSCs) carrying a human hemoglobin subunit beta gene (hHBB) in a healthy syngeneic rat model.
Methods: Time-dated pregnant Lewis dams underwent volume-matched intra-amniotic injections in all their fetuses (n = 61) of a suspension of donor HSCs genetically modified with either both a hHBB gene and a firefly luciferase reporter gene (n = 42) or the firefly luciferase reporter gene alone to control for HBB-derived protein interspecies homology (n = 19) on gestational day 17 (E17; term = E21). Donor HSCs consisted of syngeneic cells phenotyped by flow cytometry with successful hHBB transduction confirmed by ELISA prior to administration in vivo.
Spontaneous Hepatic Rupture Complicating Preeclampsia and HELLP Syndrome: A Case Report.

Spontaneous hepatic rupture is a rare complication that occurs in pregnant mothers with HELLP syndrome, or preeclampsia with severe features, or eclampsia. The most common symptom of hepatic rupture/hematoma is right upper quadrant pain or epigastric pain, which is similar to the presentation of preeclampsia with severe features. Therefore, the absence of specific signs and symptoms leads to a diagnostic dilemma and a delay in management.

Hepatitis B virus (HBV) infection is a major public health burden. In HBV endemic regions, high prevalence is also correlated with the infections acquired in infancy through perinatal transmission or early childhood exposure to HBV, the so-called mother-to-child transmission (MTCT). Children who are infected with HBV at a young age are at higher risk of developing chronic HBV infection than those infected as adults, which may lead to worse clinical outcome.

Background: Tuberculosis (TB) among women and infants during the perinatal period is not rare, particularly in countries with a high TB burden. And the risk would increase significantly following in vitro fertilization-embryo transfer (IVFET). Worse still, TB in this stage is apt to develop into severe forms in women and neonates, such as disseminated TB or tuberculous meningitis (TBM).

The aim of this study was to investigate the impact of supplementary feeding with Chinese herbal mixtures on perinatal sows, focusing on their reproductive performance, immunity and breast milk quality. Sixty healthy pregnant sows (Large white, 4 parities) were randomly allocated into five treatment groups ( = 12 per group): the control group received a basal diet, the TRT1 group received a basal diet supplemented with 2 kg/t Bazhen powder (BZP), while the TRT2, TRT3, and TRT4 groups received a basal diet supplemented with 1 kg/t, 2 kg/t, and 3 kg/t Qi-Zhu-Gui-Shao soothing liver and replenishing blood powder (QZGSP), respectively. The trial lasted for a duration of 5 weeks, commencing from day 100 of gestation and concluding on day 21 postpartum.
