Safety of Outpatient Anterior Lumbar Interbody Fusion Surgery: A Systematic Review With Meta-Analyses.

Background: Due to rapidly rising health care costs, leveraging outpatient surgery to reduce hospital inpatient burden is being explored. This study provides a systematic review of the literature on outpatient anterior lumbar interbody fusion (ALIF) with pooled analysis to determine its safety and feasibility.

Methods: Embase (Elsevier), MEDLINE (National Library of Medicine), CINAHL (EBSCO), and the Cochrane Library (Wiley) were searched on 8 April 2024 for articles mentioning the following search concepts: (1) ambulatory; (2) outpatient; and (3) ALIF surgery.

The Glymphatic System and Subarachnoid Lymphatic-Like Membrane: Recent Developments in Cerebrospinal Fluid Research.

Background: Cerebrospinal fluid (CSF) circulates throughout the ventricles, cranial and spinal subarachnoid spaces, and central spinal cord canal. CSF protects the central nervous system through mechanical cushioning, regulation of intracranial pressure, regulation of metabolic homeostasis, and provision of nutrients. Recently, investigators have characterized the glial-lymphatic (glymphatic) system, the analog of the lymphatic system in the central nervous system, and described a fourth meningeal layer; the subarachnoid lymphatic-like membrane (SLYM)relevant to the CSF.
