Disruptions in the brain's connections to the hands resulting from a cervical spinal cord injury (cSCI) can lead to severe and persistent functional impairments. The integrity of these connections is an important predictor of upper extremity recovery in stroke and may similarly act as a biomarker in cSCI. In this perspective article, we review recent findings from a large cohort of individuals with cSCI, demonstrating the predictive value of corticospinal tract (CST) integrity in cSCI-CST sparing. This research underscores that, akin to stroke, the integrity of brain-to-hand connections is crucial for predicting upper extremity recovery following cSCI. We address the limitations of commonly used metrics, such as sacral sparing and the concept of central cord syndrome. Furthermore, we offer insights on emerging metrics, such as tissue bridges, emphasizing their potential in assessing the integrity of brain connections to the spinal cord.

Autosomal recessive hypophosphatemic rickets type 2 (ARHR2) is an uncommon hereditary form of rickets characterised by chronic renal phosphate loss and impaired bone mineralisation. This results from compound heterozygous or homozygous pathogenic variants in ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1), a key producer of extracellular inorganic pyrophosphate (PPi) and an inhibitor of fibroblast growth factor23 (FGF23). ENPP1 deficiency impacts FGF23 and increases its activity.

Purpose: We sought to evaluate the incidence, natural history, and management of cystic spinal lesions following myelomeningocele/myeloschisis closure.
Methods: We performed a single-center retrospective review of all patients who underwent myelomeningocele/myeloschisis closure from 2013 to 2018 with follow-up to 5 years old.
Results: We analyzed 100 fetal repairs and 81 postnatal closures from 305 total surgeries.

The complex set of interactions between the immune system and metabolism, known as immunometabolism, has emerged as a critical regulator of disease outcomes in the central nervous system. Numerous studies have linked metabolic disturbances to impaired immune responses in brain aging, neurodegenerative disorders, and brain injury. In this review, we will discuss how disruptions in brain immunometabolism balance contribute to the pathophysiology of brain dysfunction.

Purpose: To investigate the relationship between spinal cord anatomy and the risk of curve progression in mild to moderate adolescent idiopathic scoliosis (AIS).
Methods: We prospectively included patients presenting with mild or moderate AIS (< 40 degrees). Irrespective of curve severity, patients underwent 3-dimensional MRI and were followed until skeletal maturity or surgery.

Background: Alzheimer's disease (AD) frequently coexists with cerebral small vessel disease (CSVD) is common in the aging population, yet the underlying mechanisms are not yet fully understood. Both long-term blood pressure variability (BPV) and plasma neurofilament light (PNFL) were identified as potential biomarkers for AD and CSVD. This study aims to understand the mechanisms of comorbidity between AD and CSVD by investigating the associations among BPV, PNFL, and comorbidity.
