In neuro-oncology, MR imaging is crucial for obtaining detailed brain images to identify neoplasms, plan treatment, guide surgical intervention, and monitor the tumor's response. Recent AI advances in neuroimaging have promising applications in neuro-oncology, including guiding clinical decisions and improving patient management. However, the lack of clarity on how AI arrives at predictions has hindered its clinical translation.

In this paper, we present the first publicly available 3D statistical facial shape model of babies, the Baby Face Model (BabyFM). Constructing a model of the facial geometry of babies entails specific challenges, such as occlusions, extreme and uncontrollable expressions, and data shortage. We address these challenges by proposing (1) a non-template dependent method that jointly estimates a 3D facial baby-specific template and the point-to-point correspondences; (2) a novel method to establish correspondences based on the spectral decomposition of the Laplace Beltrami Operator, which provides a more robust theoretical foundation than state-of-the-art methods; and (3) an asymmetry-swapping strategy to alleviate the shortage of large scale datasets by decoupling the identity-related and the asymmetry-related shape deformation fields.

Objective: To investigate the association between concussion history and depressive symptoms after adjusting for physical activity, substance use, and illicit drug use.

Methods: We analysed data from the Adolescent Behaviour and Experiences Survey, a nationally representative survey of adolescents in the USA. Our independent variables were history of concussion in the 12 months preceding survey completion; self-reported weekly physical activity (days per week with >60 min of physical activity, 0-7 scale); substance use over the past 30 days (yes vs no) and illicit drug use throughout lifetime (yes vs no).

Study Objectives: Deep brain stimulation (DBS) of the subthalamic nucleus (STN) may improve sleep dysfunction, a common non-motor symptom of Parkinson disease (PD). Improvement in motor symptoms correlates with DBS-suppressed local field potential (LFP) activity, particularly in the beta frequency (13 - 30 Hz). Although well-characterized in the short term, little is known about the innate progression of these oscillations across the sleep-wake cycle.

Objective: Patients with a history of surgery for single-suture craniosynostosis (SSC) as an infant often wish to participate in sports later in childhood. However, there are no established guidelines from neurosurgeons and craniofacial surgeons to guide parents in which sports their child should or should not participate. Therefore, this study aimed to evaluate the attitudes and practice patterns of experienced neurosurgeons and craniofacial surgeons regarding the counseling of caregivers of these patients about sports participation.

3D photogrammetry is a cost-effective, non-invasive imaging modality that does not require the use of ionizing radiation or sedation. Therefore, it is specifically valuable in pediatrics and is used to support the diagnosis and longitudinal study of craniofacial developmental pathologies such as craniosynostosis - the premature fusion of one or more cranial sutures resulting in local cranial growth restrictions and cranial malformations. Analysis of 3D photogrammetry requires the identification of craniofacial landmarks to segment the head surface and compute metrics to quantify anomalies.

Metastasis to vital organs remains the leading cause of cancer-related deaths, emphasizing an urgent need for actionable targets in advanced-stage cancer. The role of mitochondrial Rho GTPase 2 (MIRO2) in prostate cancer growth was recently reported; however, whether MIRO2 is important for additional steps in the metastatic cascade is unknown. Here, we show that knockdown of MIRO2 ubiquitously reduces tumor cell invasion in vitro and suppresses metastatic burden in prostate and breast cancer mouse models.

Background: Women make up only 23% to 30% of recipients for deep brain stimulation (DBS) surgery for Parkinson's disease (PD), a discrepancy that is not accounted for by differences in disease incidence. One of the many factors that may contribute to this gap includes gender differences in decision-making.

Objective: The aim was to explore how women and men approach the decision for DBS in terms of informational needs, weighing risks and benefits, and decision-making.

Chordomas are rare, generally slow-growing spinal tumors that nonetheless exhibit progressive characteristics over time, leading to malignant phenotypes and high recurrence rates, despite maximal therapeutic interventions. The tumors are notoriously resistant to therapies and are often located in regions that complicate achieving gross total resections. Cell lines from these tumors are rare as well.
