Pulmonary hypertension with bronchopulmonary dysplasia: Aichi cohort study.

Background: The incidence of pulmonary hypertension (PH) associated with bronchopulmonary dysplasia (BPD) has not been investigated in regional cohorts. The aim of this study was to clarify the incidence of PH associated with BPD in all very low birthweight infants (VLBWIs) born during the study period in Aichi Prefecture, Japan.

Methods: We conducted a retrospective observational cohort study of all VLBWIs born in Aichi Prefecture.

Long-term follow-up of a patient with autosomal dominant lower extremity-predominant spinal muscular atrophy-2 due to a BICD2 variant.

Introduction: Bicaudal D homolog 2 (BICD2) is a causative gene of autosomal-dominant lower extremity-predominant spinal muscular atrophy-2 (SMA-LED2). The severity of SMA-LED2 varies widely, ranging from cases in which patients are able to walk to cases in which severe joint contractures lead to respiratory failure. In this study, we report the long-term course of a case of SMA-LED2 in comparison with previous reports.

Factors related to survival discharge in trisomy 18: A retrospective multicenter study.

Infants with trisomy 18 (T18) previously had a poor prognosis; however, the intensive care of these patients has markedly diversified the prognosis. We investigated the current situation of patients with T18, clarified factors for survival discharge, and surveyed actual home healthcare. A total of 117 patients with T18 admitted to nine institutions between 2000 and 2015 were retrospectively investigated.

Factors related to home health-care transition in trisomy 13.

Trisomy 13 (T13) is accompanied by severe complications, and it can be challenging to achieve long-term survival without aggressive treatment. However, recently, some patients with T13 have been receiving home care. We conducted this study to investigate factors related to home health-care transition for patients with T13.

Prognostic factors of hydrops fetalis with pleural effusion.

Background: Hydrops fetalis (HF) has a low survival rate, particularly in the case of preterm birth. In addition, the severity index of HF has not been fully investigated yet. The aim of this study was to clarify the prognostic factors of HF with pleural effusion.

Identification of novel FATP4 mutations in a Japanese patient with ichthyosis prematurity syndrome.

Ichthyosis prematurity syndrome (IPS) is a rare autosomal recessive disorder characterized by prematurity, a thick caseous scale at birth and lifelong atopic diathesis. Here, we describe the first Japanese case of IPS and report novel compound heterozygous mutations (p.C403Y and p.

Carbohydrate and energy metabolism in the brain of rats with thromboxane A2-induced fetal growth restriction.

Fetal growth restriction (FGR) remains a cause of perinatal brain injury, sometimes leading to neurological and intellectual impairment. Although the mechanisms and pathophysiology of CNS injuries have not been elucidated completely, it is possible carbohydrate and energy metabolism may have an important role in the FGR brain. In this study, FGR was induced in rats by administration of synthetic thromboxane A2 (STA2).

An animal model of intrauterine growth retardation induced by synthetic thromboxane a(2).

Objective: Intrauterine growth retardation (IUGR) is an important cause of prenatal and neonatal morbidity, and neurologic abnormalities. Although several animal models of IUGR have been developed for scientific investigation, few models approximate the pathophysiology in human fetal growth failure resulting from pregnancy-induced hypertension and preeclampsia. We developed an animal model of IUGR in which fetal growth restriction was induced by administering a synthetic thromboxane A(2) analogue (STA(2)) to the mother.
