Invasive devices to monitor the intraspinal perfusion pressure in the hemodynamic management of acute spinal cord injury: A systematic scoping review.

Background: Various methods for measuring intrathecal pressure (ITP) after spinal cord injury (SCI) to guide hemodynamic management have been investigated. To synthesize the current literature, this current study conducted a scoping review of the use of intrathecal devices to monitor ITP during acute management of SCI with the aim of understanding the association between ITP monitoring with physiological and clinical outcomes.

Methods: A systematic review of literature following the Cochrane Handbook for Systematic Reviews of Interventions and Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement.

Pedicle screw placement in the cervical vertebrae using augmented reality-head mounted displays: a cadaveric proof-of-concept study.

Background: The accurate and safe positioning of cervical pedicle screws is crucial. While augmented reality (AR) use in spine surgery has previously demonstrated clinical utility in the thoracolumbar spine, its technical feasibility in the cervical spine remains less explored.

Purpose: The objective of this study was to assess the precision and safety of AR-assisted pedicle screw placement in the cervical spine.

Virtual, Augmented, and Mixed Reality Applications for Surgical Rehearsal, Operative Execution, and Patient Education in Spine Surgery: A Scoping Review.

: Advances in virtual reality (VR), augmented reality (AR), and mixed reality (MR) technologies have resulted in their increased application across many medical specialties. VR's main application has been for teaching and preparatory roles, while AR has been mostly used as a surgical adjunct. The objective of this study is to discuss the various applications and prospects for VR, AR, and MR specifically as they relate to spine surgery.

Utilization of Augmented Reality Head-Mounted Display for the Surgical Management of Thoracolumbar Spinal Trauma.

: Augmented reality head-mounted display (AR-HMD) is a novel technology that provides surgeons with a real-time CT-guided 3-dimensional recapitulation of a patient's spinal anatomy. In this case series, we explore the use of AR-HMD alongside more traditional robotic assistance in surgical spine trauma cases to determine their effect on operative costs and perioperative outcomes. : We retrospectively reviewed trauma patients who underwent pedicle screw placement surgery guided by AR-HMD or robotic-assisted platforms at an academic tertiary care center between 1 January 2021 and 31 December 2022.

Rapid Implementation of a 3-Dimensional-Printed Patient-Specific Titanium Sacrum Implant for Severe Neuropathic Spinal Arthropathy and Guide to Compassionate US Regulatory Approval.

Background And Objective: Rapid design and production of patient-specific 3-dimensional-printed implants (3DPIs) present a novel opportunity to restore the biomechanically demanding integrity of the lumbopelvic junction. We present a unique case of a 61-year-old patient with severe neuropathic spinal arthropathy (Charcot spine) who initially underwent a T4-to-sacrum spinal fusion. Massive bone destruction led to dissociation of his upper body from his pelvis and legs.

Predictors of Postoperative Segmental and Overall Lumbar Lordosis in Minimally Invasive Transforaminal Lumbar Interbody Fusion: A Consecutive Case Series.

Study Design: Retrospective Case-Series.

Objectives: Due to heterogeneity in previous studies, the effect of MI-TLIF on postoperative segmental lordosis (SL) and lumbar lordosis (LL) remains unclear. Therefore, we aim to identify radiographic factors associated with lordosis after surgery in a homogenous series of MI-TLIF patients.

Use of Terminology and the Effect of Training on Auditory-Perceptual Ratings of Speaking Voice by Singing Teachers.

Objectives: The purpose of this study was to investigate group differences between singing teachers and speech-language pathologists when rating dysphonic speaking voices and whether training using reference samples and the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) improves inter-rater reliability between and among the two groups. Differences in use of terminology and ratings could reveal potential for miscommunication in the team treatment of singers with voice disorders.

Study Design: This is a prospective pre test post test cohort study with between and within group comparisons.

Perceptual Measures of Boychoir Voices During the Phases of Pubertal Voice Mutation.

Background/objectives: Vocal changes in the male singing voice associated with puberty are variable and often unpredictable resulting in challenges for the singer and the choral director. Limited knowledge regarding the physiologic changes in the vocal mechanism as they correlate to perceptual variations observed in the male adolescent singer exists in the literature. The purpose of this study was to examine pitch breaks and perceptual characteristics of vocal quality during singing tasks for boys in various stages of the male changing voice.

Homophily in the career mobility of China's political elite.

We argue that leadership promotion in China's political elite relies on homophily for signals of trustworthiness and future cooperative behavior more than on economic performance. We first point to the limitation of the economic performance argument from within the framework of China's specific M-form state structure, and then we proffer a sociological explanation for why higher-level elites in China rely on homophilous associations in recruiting middle-level elites to the top positions of state. Using a unique dataset covering China's provincial leaders from 1979 to 2011, we develop a homophily index focusing on joint origin, joint education and joint work experience.

Assessment of Vibratory Characteristics in Children Following Airway Reconstruction Using Flexible and Rigid Endoscopy and Stroboscopy.

Importance: Up to half of children have substantial dysphonia after airway reconstruction. Visual assessment of vocal function is valuable. Feasibility of flexible and rigid endoscopy has been reported; however, the clinical utility of stroboscopy has not been examined.
