Article Synopsis
  • Papillary tumor of the pineal region (PTPR) is a rare and unique tumor characterized by specific molecular and histopathologic features, with limited prior research on its variations and clinical presentations.
  • In a study of 76 confirmed PTPR cases, researchers identified two main methylation groups (PTPR-A and PTPR-B) and further classified PTPR-B into two subtypes (B1 and B2) based on DNA methylation profiles and genomic variations.
  • Clinical outcomes revealed that nearly half of the patients experienced tumor progression, with significant differences in outcomes among the identified subtypes, highlighting the tumor's molecular diversity and potential for recurrence.

In patients with sickle cell disease (SCD) and beta-thalassemia major (TM), allogeneic hematopoietic stem cell transplantation (HSCT) was considered the only curative treatment option with a good survival rate. However, with the recent approval of gene therapies, more information is needed to understand the benefits and risks of these interventions. We performed a retrospective analysis of the Kids Inpatient Database to describe demographic features, short-term complications, and hospital charges of patients with SCD and TM treated with HSCT during 2006-2019 in the United States.

With remarkable electrical and optical switching properties induced at low power and near room temperature (68 °C), vanadium dioxide (VO) has sparked rising interest in unconventional computing among the phase-change materials research community. The scalability and the potential to compute beyond the von Neumann model make VO especially appealing for implementation in oscillating neural networks for artificial intelligence applications, to solve constraint satisfaction problems, and for pattern recognition. Its integration into large networks of oscillators on a Silicon platform still poses challenges associated with the stabilization in the correct oxidation state and the ability to fabricate a structure with predictable electrical behavior showing very low variability.

Phase-encoded oscillating neural networks offer compelling advantages over metal-oxide-semiconductor-based technology for tackling complex optimization problems, with promising potential for ultralow power consumption and exceptionally rapid computational performance. In this work, we investigate the ability of these networks to solve optimization problems belonging to the nondeterministic polynomial time complexity class using nanoscale vanadium-dioxide-based oscillators integrated onto a Silicon platform. Specifically, we demonstrate how the dynamic behavior of coupled vanadium dioxide devices can effectively solve combinatorial optimization problems, including Graph Coloring, Max-cut, and Max-3SAT problems.

Article Synopsis
  • Children with relapsed or refractory cancers have few treatment options and limited predictive biomarkers, making personalized care challenging.
  • This study explores functional precision medicine (FPM), which combines genomic profiling with drug sensitivity testing to identify effective treatments when standard options fail.
  • Results showed that 76% of patients received treatment recommendations from FPM, with many experiencing significant improvements in progression-free survival compared to previous therapies, highlighting FPM's potential in improving care for pediatric cancer patients.
