Alignment in motion: Fall risk in spine patients and the effect of vision, support surface, and adaptation on the cone of economy.

Background: Several assessment tools have been developed to estimate a patient's likelihood risk of falling. None of these measures estimate the contributions of the visual, vestibular, and somatosensory systems to fall risk, especially in patients with degenerative lumbar spine disease.

Methods: Degenerative lumbar spine patients with radiculopathy (LD) and healthy subjects who were 35-70 years old without spine complaints were recruited.

The role of miR-155-5p in inflammation and mechanical loading during intervertebral disc degeneration.

Background: Intervertebral disc (IVD) degeneration is a multifactorial pathological process resulting in the dysregulation of IVD cell activity. The catabolic shift observed in IVD cells during degeneration leads to increased inflammation, extracellular matrix (ECM) degradation, aberrant intracellular signaling and cell loss. Importantly, these pathological processes are known to be interconnected and to collectively contribute to the progression of the disease.

Exploring the Impact of TLR-2 Signaling on miRNA Dysregulation in Intervertebral Disc Degeneration.

Toll-like receptors (TLRs) are key mediators of inflammation in intervertebral disc (IVD) degeneration. TLR-2 activation contributes to the degenerative process by increasing the expression of extracellular matrix-degrading enzymes, pro-inflammatory cytokines, and neurotrophins. As potent post-transcriptional regulators, microRNAs can modulate intracellular mechanisms, and their dysregulation is known to contribute to numerous pathologies.

Patient-Reported Outcomes for Spine Oncology: A Narrative Review.

Spine tumors, both primary and metastatic, impose significant morbidity and mortality on patients and physicians. Patient-reported outcomes are valuable tools to assess a patient's impression of their health status and enhance communication between physicians and patients.

Socioeconomic disadvantage is correlated with worse PROMIS outcomes following lumbar fusion.

Background Context: Socioeconomic status (SES) has been associated with differential healthcare outcomes and may be proxied using the area-deprivation index (ADI). Few studies to date have investigated the role of ADI on patient-reported outcomes and clinically meaningful improvement following lumbar spine fusion surgery.

Purpose: The purpose of this study is to investigate the role of SES on lumbar fusion outcomes using Patient-Reported Outcomes Measurement Information System (PROMIS) surveys.

Predicting 30-day mortality after surgery for metastatic disease of the spine: the H-FAILS score.

Purpose: Scoring systems for metastatic spine disease focus on predicting long- to medium-term mortality or a combination of perioperative morbidity and mortality. However, accurate prediction of perioperative mortality alone may be the most important factor when considering surgical intervention. We aimed to develop and evaluate a new tool, the H-FAILS score, to predict 30-day mortality after surgery for metastatic spine disease.
