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.

Impact of HA-PCI on self-reported cognitive functioning and brain metastases in small-cell lung cancer: Pooled findings of NCT01780675 and PREMER trials.

Background: Cognitive decline is an arising concern in patients who need cranial irradiation. We used the pooled longitudinal individual patient data of two phase III trials: NCT01780675 and PREMER to investigate whether hippocampal avoidance (HA)-PCI is associated with improved self-reported cognitive functioning (SRCF) compared with PCI without increasing brain metastases (BM) development within the HA area.

Methods: Patients with stage I-IV small cell lung cancer (SCLC) were randomized to PCI or HA-PCI.

Workshop report: The role of Earth Observation for multi-(hazard-)risk assessment and management.

At the 2024 General Assembly of the European Geophysical Union, a workshop was organized to introduce the EO4Multihazards project and its three main research questions. The workshop included a project overview, panel discussion, group activities, and a feedback session. It also showcased an interactive poster.

The effect of charge screening for cationic surfactants on the rigidity of interfacial nanoparticle assemblies.

Hypothesis: Functionalizing colloidal particles with oppositely charged surfactants is crucial for stabilizing emulsions, foams, all-liquid structures, and bijels. However, surfactants can reduce the attachment energy, the driving force for colloidal self-assembly at interfaces. An open question remains on how the inherent interfacial activity of cationic surfactants influences the interfacial rigidity of particle-laden interfaces.
