Neurodegenerative diseases, particularly Alzheimer's disease and other dementias as well as Parkinson's disease, are emerging as profoundly significant challenges and burdens to global health, a trend highlighted by the most recent Global Burden of Disease (GBD) 2021 studies. This growing impact is closely linked to the demographic shift toward an aging population and the potential long-term repercussions of the COVID-19 pandemic, both of which have intensified the prevalence and severity of these conditions. In this review, we explore several critical aspects of this complex issue, including the increasing global burden of neurodegenerative diseases, unmet medical and social needs within current care systems, the unique and amplified challenges posed by the COVID-19 pandemic, and potential strategies for enhancing healthcare policy and practice.

Background: The extubation time is critical during the intensive care unit stay in aneurysmal subarachnoid hemorrhage (aSAH) patients. The current conventional parameters for predicting extubation failure (EF) and extubation time may not be suitable for this population. Here, we aimed to identify factors associated with EF in aSAH patients.

Local progression of primary skull base chordoma (PSBC) is a sign of treatment failure. Predicting the postoperative progression of PSBC can aid in the development of individualized treatment plans to improve patients' progression-free survival (PFS) after surgery. This study aimed to develop a multiparametric MRI-based fusion radiomic model (FRM) and clinicoradiomic model (CRM) via radiomic and clinical analysis and to explore their validity in predicting postoperative progression in PSBC patients before surgery.

Background: Sepsis-induced neurodegeneration and cognitive dysfunction remain critical challenges worldwide. Vitamin D was reported to reduce neuronal injury and neurotoxicity and its deficiency was associated with neurocognitive disorders. This study investigates the mechanisms by which vitamin D exerts neuroprotective potential against damage-associated molecular patterns (DAMPs), specifically extracellular histones, in sepsis-related brain dysfunction.

In living systems, proteins participate in various physiological processes and the clustering of multiple proteins is essential for efficient signaling. Therefore, understanding the effects of the number, distance and orientation of proteins is of great significance. With programmability and addressability, DNA origami technology has enabled fabrication of sophisticated nanostructures with precise arrangement and orientation control of proteins to investigate the effects of these parameters on protein-involved cellular processes.

The adolescent years are a period of profound change, both physically and psychologically. For many, these years are marked by excitement and exploration, but for others, they are fraught with challenges that can lead to significant mental health issues. Depression, in particular, has become an increasingly prevalent concern among adolescents worldwide, and its multifaceted etiology requires a comprehensive approach to understanding and intervention.

PROPELLER MRI has been shown effective for rigid motion compensation, while the performance of existing PROPELLER reconstruction methods critically depend on selecting a proper reference blade. In this work, we proposed a robust implementation for PROPELLER reconstruction, which was incorporated with different reference selection methods, including single blade reference (SBR), combined blades reference (CBR), grouped blades reference (GBR) and Pipe et al.'s revised method, which requires no blade reference (NBR).

Purpose: to propose a two-step non-local principal component analysis (PCA) method and demonstrate its utility for denoising diffusion tensor MRI (DTI) with a few diffusion directions.
Methods: A two-step denoising pipeline was implemented to ensure accurate patch selection even with high noise levels and was coupled with data preprocessing for g-factor normalization and phase stabilization before data denoising with a non-local PCA algorithm. At the heart of our proposed pipeline was the use of a data-driven optimal shrinkage algorithm to manipulate the singular values in a way that would optimally estimate the noise-free signal.

Aim: The interaction between inflammatory biomarkers (high-sensitivity C-reactive protein, hsCRP) and antioxidants (uric acid, UA) regarding prognosis after ischemic stroke or transient ischemic attack (TIA) remains inadequately explored. This study aimed to assess (1) the individual and joint effects of hsCRP and UA, and (2) the neuroprotective role of UA in patients with elevated hsCRP levels concerning poor functional outcomes at 90 days.
Methods: A prospective cohort study was conducted involving 2140 consecutive ischemic stroke or TIA patients with hsCRP and UA levels.
