Hippocampal avoidance prophylactic cranial irradiation (HA-PCI) for small cell lung cancer better preserves white matter networks compared to conventional PCI.

Background: Hippocampal avoidance during prophylactic cranial irradiation (HA-PCI) is proposed to reduce neurocognitive decline, while preserving the benefits of PCI. We evaluated whether (HA-)PCI induces changes in white matter (WM) microstructure and whether sparing the hippocampus has an impact on preserving brain network topology. Additionally, we evaluated associations between topological metrics with hippocampal volume and neuropsychological outcomes.

A systematic review of interventions for neurocognitive dysfunctions in patients and survivors of a pediatric brain tumor.

Due to a high burden of neurocognitive impairment on patients with a pediatric brain tumor, interventions mitigating these symptoms are highly needed. Currently, evidence on the efficacy and feasibility of such interventions remains scarce. A systematic literature study was performed based on four different databases (PubMed, Web of Science Core Collection, Embase, and PsycArticles).

Peering into the gaps: Long-read sequencing illuminates structural variants and genomic evolution in the Australasian snapper.

Even before genome sequencing, genetic resources have supported species management and breeding programs. Current technologies, such as long-read sequencing, resolve complex genomic regions, like those rich in repeats or high in GC content. Improved genome contiguity enhances accuracy in identifying structural variants (SVs) and transposable elements (TEs).

Brain network topology and its cognitive impact in adult glioma survivors.

Structural brain network topology can be altered in case of a brain tumor, due to both the tumor itself and its treatment. In this study, we explored the role of structural whole-brain and nodal network metrics and their association with cognitive functioning. Fifty WHO grade 2-3 adult glioma survivors (> 1-year post-therapy) and 50 matched healthy controls underwent a cognitive assessment, covering six cognitive domains.
