Background: The preterm infants are at risk of cerebellar injury and the risk factors for necrotizing enterocolitis (NEC) associated cerebellar injury are not fully understood.
Aim: Determine the risk factors of cerebellar injury in infants with surgical necrotizing enterocolitis (NEC).
Methods: Retrospective study compared clinical/pathological information between surgical NEC infants with and those without cerebellar injury detected on brain MRI obtained at term equivalent age. Cerebellar Injury patterns that we identified on MRI brain were cerebellar hemorrhage, siderosis and/or cerebellar volume loss.
Results: Cerebellar injury (21/65, 32.3%) in preterm infants with NEC was associated with patent ductus arteriosus (PDA) (18/21(85.7%) vs. 25/44(56.8%); p = 0.021), blood culture positive sepsis (13/21 (61.9%) vs. 11/44 (25%); p = 0.004) following NEC, predominantly grew gram positive bacteria (9/21(42.9%) vs. 4/44(9.1%); p = 0.001), greater red cell transfusion, higher rates of cholestasis following NEC and differences in intestinal histopathology (more hemorrhagic and reparative lesions) on univariate analysis. Those with cerebellar injury had higher grade white matter injury (14/21 (66.7%) vs. 4/44(9.1%) p = 0.0005) and higher-grade ROP (70.6% vs. 38.5%; p = 0.027) than those without cerebellar injury.On multilogistic regression, the positive blood culture sepsis (OR 3.9, CI 1.1-13.7, p = 0.03), PDA (OR 4.5, CI 1.0-19.9, p = 0.04) and severe intestinal pathological hemorrhage (grade 3-4) (OR 16.9, CI 2.1-135.5, p = 0.007) were independently associated with higher risk of cerebellar injury.
Conclusion: Preterm infants with surgical NEC with positive blood culture sepsis, PDA, and severe intestinal hemorrhagic lesions (grade 3-4) appear at greater risk for cerebellar injury.

The pathogenesis of type I Chiari malformation (CIM) is complex and remains unclear. The theory of posterior cranial fossa incompatibility has gained widespread acceptance in recent years. In the patients with CIM combined with syringomyelia, scoliosis is a common occurrence, with severe cases often leading to complications that necessitate surgical intervention.

Paraneoplastic cerebellar degeneration (PCD) is a rapidly progressive, immune-mediated syndrome characterized by the degeneration of Purkinje cells, often associated with the presence of antibodies targeting intracellular antigens within these cells. These autoantibodies are implicated in the induction of cytotoxicity, leading to Purkinje cell death, as demonstrated in in vitro models. However, the precise roles of antibodies and T lymphocytes in mediating neuronal injury remain a subject of ongoing research, with T cells appearing to be the main effectors of cerebellar injury.

Background: Postoperative pediatric cerebellar mutism syndrome (ppCMS) poses serious morbidity after posterior fossa tumor surgery. Neuroimaging studies aim to understand its pathophysiology, yet these vary in methodology and outcome measures. Therefore, we systematically reviewed the current literature to evaluate the evidence for differences in neuroimaging features between children with and without ppCMS.

This study developed an artificial intelligence (AI) system using a local-global multimodal fusion graph neural network (LGMF-GNN) to address the challenge of diagnosing major depressive disorder (MDD), a complex disease influenced by social, psychological, and biological factors. Utilizing functional MRI, structural MRI, and electronic health records, the system offers an objective diagnostic method by integrating individual brain regions and population data. Tested across cohorts from China, Japan, and Russia with 1,182 healthy controls and 1,260 MDD patients from 24 institutions, it achieved a classification accuracy of 78.

The glycosylphosphatidylinositol (GPI) is a glycol-lipid that anchors several proteins to the cell surface. The GPI-anchor pathway is crucial for the correct function of proteins involved in cell function, and it is fundamental in early neurogenesis and neural development. The PIG gene family is a group of genes involved in this pathway with six genes identified so far, and defects in these genes are associated with a rare inborn metabolic disorder manifesting with a spectrum of clinical phenotypes in newborns and children.
