The association between serum 25-hydroxyvitamin D levels and retinopathy of prematurity in preterm infants.

Objective: This study aimed to investigate the correlation between serum 25-hydroxyvitamin D (25(OH)D) levels and retinopathy of prematurity (ROP) in premature infants one month after birth.

Methods: Preterm infants (gestational age <32 weeks) admitted to the Affiliated Hospital of Qingdao University from 2017 to 2022 were divided into ROP and non-ROP groups based on ROP occurrence any stage. Serum 25(OH)D levels and clinical data were compared between the two groups at 1 month after birth, and the relationship between vitamin D levels and ROP was analyzed.

X-linked intellectual developmental disorder with onset of neonatal heart failure: A case report and literature review.

X-linked intellectual developmental disorder is a rare X-linked genetic disease, manifested as heart disease, intellectual impairment, and developmental disorders. We report a male infant who presented with dyspnea after birth. Physical examination on admission revealed poor responsiveness, deep eye sockets, a small mandible, abnormalities of the outer ears, and reduced limb muscle tone.

Combined gestational age and serum fucose for early prediction of risk for bronchopulmonary dysplasia in premature infants.

Objective: As the predominant complication in preterm infants, Bronchopulmonary Dysplasia (BPD) necessitates accurate identification of infants at risk and expedited therapeutic interventions for an improved prognosis. This study evaluates the potential of Monosaccharide Composite (MC) enriched with environmental information from circulating glycans as a diagnostic biomarker for early-onset BPD, and, concurrently, appraises BPD risk in premature neonates.

Materials And Methods: The study incorporated 234 neonates of ≤32 weeks gestational age.

An outbreak of nosocomial infection of neonatal aseptic meningitis caused by echovirus 18.

We describe an outbreak of echovirus 18 infection involving 10 patients in our neonatal intensive care unit (an attack rate of 33%). The mean age at the onset of illness was 26.8 days.

Infantile Pompe disease with intrauterine onset: a case report and literature review.

Background: Pompe disease is a rare autosomal recessive disease. Acid alpha-glucosidase (GAA) deficiency leads to glycogen storage in lysosomes, causing skeletal, cardiac, and smooth muscle lesions. Pompe disease is progressive, and its severity depends on the age of onset.

Chorionic villus-derived mesenchymal stem cells induce E3 ligase TRIM72 expression and regulate cell behaviors through ubiquitination of p53 in trophoblasts.

Preeclampsia is a significant contributor for maternal or fetal morbidity and mortality, which is characterized by reduced invasion capacity of trophoblasts and is regulated by extracellular matrix (ECM). It is still under investigation whether chorionic villus-derived mesenchymal stem cells (CVMSC) could affect the functionality of trophoblasts. In this study, CVMSC-derived exosomes were isolated; their effect on trophoblasts was investigated based on the CCK8 assay, migration assay, and apoptosis detection.

Congenital nephrotic syndrome associated with 22q11.2 duplication syndrome in a Chinese family and functional analysis of the intronic NPHS1 c. 3286 + 5G > A mutation.

Background: Congenital nephrotic syndrome (CNS), which is defined as heavy proteinuria, hypoalbuminemia, hyperlipidemia and edema, is most caused by monogenic defects in structural proteins of the glomerular filtration barrier in the kidneys. 22q11.2 duplication syndrome was a chromosomal disease with variable clinical featuresranging from normal to mental retardation and with congenital defects.

Impact of Xenon on CLIC4 and Bcl-2 Expression in Lipopolysaccharide and Hypoxia-Ischemia-Induced Periventricular White Matter Damage.

Background: Premature birth is a significant health care burden. Xenon (Xe) is a general anesthetic with neuroprotective effects.

Objectives: Here, we investigate the neuroprotective role of Xe in a lipopolysaccharide (LPS)- and hypoxia-ischemia (HI)-induced white matter damage (WMD) model.

2-Phenyl-1H-1,3,7,8-tetra-azacyclo-penta-[l]phenanthrene.

There are two molecules in the asymmetric unit of the title compound, C(19)H(12)N(4). One is almost planar [dihedral angle between the fused-ring system and the phenyl ring = 2.16 (13)°] and one is somewhat twisted [dihedral angle = 13.
