Real-world data (RWD) and real-world evidence (RWE) are increasingly gaining attention in supporting drug regulatory decision making. This study assessed knowledge, opinions, and usage patterns of key stakeholders regarding the status of RWD/RWE and AI implementation in health technology assessment (HTA) and drug regulation and aimed to identify the primary obstacles hindering adoption of these technologies.

The ability to represent locations across multiple dimensions of space is a core function of cognitive maps. While the influence of boundary-dependent environmental geometry on spatial representations has been extensively studied in 2D spaces, less is known about the role of boundaries for volumetric spatial memory.

Leber’s hereditary optic neuropathy (LHON) is the most common mitochondrial disease, and was the first to be linked to mitochondrial DNA (mtDNA) variations. Recently, autosomal recessive forms of LHON were described in addition to the classical mtDNA-associated forms. [...]

Increased white matter hyperintensities (WMHs) have been reported in genetic frontotemporal dementia (FTD) in small studies, but the sequence of WMH abnormalities relative to other biomarkers is unclear.Using a large dataset (n = 763 GENFI2 participants), we measured WMHs and examined them across genetic FTD variants and stages. Cortical and subcortical volumes were parcellated, and serum neurofilament light chain (NfL) levels were measured. [...]

Postseizure (postictal) symptoms are regularly encountered in epilepsy and can be life threatening, yet their neurobiological underpinnings remain understudied. Using two-photon or widefield imaging, field potential and unit recordings, optogenetics, and basic behavioral assessment under healthy conditions or viral encephalitis, we studied seizures and postictal symptoms in mice. [...]

To estimate the proportion of molecular genetic diagnoses in a real-world, phenotypically heterogeneous patient cohort that are amenable to antisense oligonucleotide (ASO) treatment.We retrospectively applied the N=1 Collaborative's Variant Assessments toward Eligibility for Antisense Oligonucleotide Treatment guidelines to all diagnostic variants found by clinical genome-wide sequencing at a single pediatric hospital in 532 patients over a 6-year period. Variants were classified as either 'eligible,' 'likely eligible,' 'unlikely eligible,' or 'not eligible' in relation to the different ASO approaches, or 'unable to assess.'In total, 25 unique variants across 26 patients (4.9% of 532 patients) were eligible or likely eligible for ASO treatment at a molecular genetic level, via canonical exon skipping (4), splice correction (3), or messenger RNA knockdown (19). [...]

Neuronal dendrites integrate excitatory input. They can perform local computations such as coincidence detection by amplifying synchronized local input and dendritic spiking. [...]

Filter-decomposition-based group equivariant convolutional neural networks (CNNs) have shown promising stability and data efficiency for 3D image feature extraction. However, these networks, which rely on parameter sharing and discrete transformation groups, often underperform in modern deep neural network architectures for processing volumetric images with dense 3D textures, such as the common 3D medical images [...]
