Evaluating Dysphagia Duration and Severity After ACDF in Patients With Underlying Dysphagia - A Prospective, Multicenter Study.

Study Design: Prospective Cohort Study.

Objectives: The purpose of this study was to prospectively evaluate the impact of preoperative dysphagia on the postoperative incidence and severity of dysphagia in patients undergoing ACDF at multiple institutions.

Methods: After IRB approval, patients over 18 years of age who underwent an elective ACDF for degenerative conditions were prospectively enrolled at two academic centers from 2018 to 2021.

Cross-sectional area of the longus colli and cervical degenerative spondylolisthesis: A retrospective review evaluating this anatomic consideration.

Background: Limited literature is available to define the impact of the longus colli muscle, a deep flexor of the spine, on cervical spine stability despite its close proximity to the vertebrae.

Aims And Objectives: The purpose of this study was to determine if longus colli cross-sectional area (CSA) is associated with the severity preoperative cervical degenerative spondylolisthesis.

Materials And Methods: Patients undergoing elective anterior cervical discectomy and fusion (ACDF) for cervical spondylolisthesis between 2010-2021 were retrospectively identified.

Short-Segment versus Long-Segment Spinal Fusion Constructs for the Treatment of Adult Degenerative Scoliosis: A Comparison of Clinical Outcomes.

Objective: To compare clinical outcomes of patients diagnosed with degenerative scoliosis undergoing short-segment versus long-segment spinal fusion.

Methods: A retrospective cohort study was conducted of patients with degenerative thoracolumbar scoliosis undergoing elective spinal fusion at a single academic medical center. Cohorts were divided into short-segment (<3) or long-segment (≥3) groups.

Incidence and predictors of ophthalmic artery occlusion in intra-arterial chemotherapy for retinoblastoma.

Background: Retinoblastoma is the most common primary intraocular malignancy in children.

Objective: To determine the incidence of ophthalmic artery (OA) occlusion in patients treated with selective ophthalmic artery catheterization (OAC) for chemotherapy infusion for retinoblastoma. Also, to evaluate technical, anatomical, tumorous, and patient-related factors that are predictors of OA occlusion.

Collagen barrier membranes do not adsorb hypoxia mimetic activity-Activity of gingival fibroblasts cultured directly on collagen barrier membranes loaded with hypoxia mimetic agents.

Hypoxia-based strategies for applications in oral surgery and periodontology have been proposed where collagen barrier membranes (CBM) are loaded with hypoxia mimetic agents (HMA) to induce a pro-angiogenic response. While it was found that CBM release HMA, it remained unclear if CBM adsorb HMA activity. Here we evaluated the response of oral cells cultured on CBM, supplemented with the HMA dimethyloxalylglycine (DMOG), desferrioxamine (DFO), and l-mimosine (l-MIM).
