Association between the C-reactive protein/albumin ratio and mortality in older Japanese patients with dysphagia.

Background: C-reactive protein-to-albumin ratio (CRP/ALB) has been proven to represent a biomarker for predicting prognosis in many groups of patients with severe diseases. However, few studies have investigated the association between CRP/ALB and mortality in Japan older people with dysphagia patients.

Objective: This retrospective cohort study aimed to assess the prognostic value of C-reactive protein/albumin ratio (CAR) in older Japanese patients with dysphagia.

Meta-analysis of the clinical efficacy and safety of oblique lateral interbody fusion and transforaminal interbody fusion in the treatment of degenerative lumbar spondylolisthesis.

Objective: The aim of this study was to comprehensively evaluate the efficacy of oblique lateral interbody fusion (OLIF) and transforaminal lumbar interbody fusion (TLIF) in the treatment of degenerative lumbar spondylolisthesis by meta-analysis.

Methods: A computer-based search of PubMed, Cochrane Library, Embase, Web of Science Core Collection databases, the China National Knowledge Infrastructure, China Biology Medicine, and Wanfang Digital Periodicals was conducted from the time of inception of each database to December 2021. The review process was conducted according to the PRISMA guidelines and registered in the PROSPERO database.

Percutaneous full endoscopic C1 laminectomy for developmental atlantal stenosis with myelopathy: a case report of three cases and review of the literature.

Background: Developmental atlantal stenosis with myelopathy (DASM) in adults is a rare disease that only sporadic cases have been reported over the years. C1 laminectomy (C1L) is one of the most common operations for its treatment. However, as an open surgery, it has shortcomings such as large trauma and slow postoperative rehabilitation, and minimally invasive spine surgery (MISS) offers alternative treatment options with advantages.

Traditional Chinese medicine active ingredients-based selenium nanoparticles regulate antioxidant selenoproteins for spinal cord injury treatment.

Background: As Traditional Chinese Medicine (TCM) drugs, Huangqi and Danshen are always applied in combination for spinal cord injury (SCI) treatment based on the compatibility theory of TCM. Astragalus Polysaccharidesis (APS) and Tanshinone IIA (TSIIA) are the main active ingredients of Huangqi and Danshen, and they both possess neuroprotective effects through antioxidant activities. However, low solubility and poor bioavailability have greatly limited their application.

Thoracic full-endoscopic unilateral laminotomy with bilateral decompression for treating ossification of the ligamentum flavum with myelopathy.

Background: The aim of the present study was to evaluate the curative effect and safety of thoracic full-endoscopic unilateral laminotomy with bilateral decompression (TE-ULBD) for treating ossification of the ligamentum flavum (OLF) with myelopathy.

Methods: Between January 2015 and December 2018, 23 consecutive patients with symptomatic thoracic OLF were treated with TE-ULBD. Of these, 21 (13 women and 8 men, aged 49-75 years) were included in the study and followed up for a minimum of 1 year.

Electromagnetic navigation-assisted percutaneous endoscopic foraminoplasty and discectomy for lumbar disc herniation: technical note and preliminary results.

Background: The aim of the present study was to report a new technique for electromagnetic navigation system-assisted percutaneous full-endoscopic foraminoplasty and discectomy and to evaluate the efficacy of this technology in the treatment of lumbar disc herniation (LDH).

Methods: This is a retrospective study. Seventeen patients who underwent electromagnetic navigation system-assisted percutaneous full-endoscopic foraminoplasty and discectomy in our department from September to November 2018 were included in the study.

Percutaneous Full-Endoscopic Lumbar Foraminoplasty and Decompression by Using a Visualization Reamer for Lumbar Lateral Recess and Foraminal Stenosis in Elderly Patients.

Background: Percutaneous endoscopic lumbar discectomy has been widely used to treat lumbar disc herniation; its advantages are less trauma, faster recovery, lower costs, and higher percentage of patient satisfaction compared with open surgery. Treatment of lumbar spinal stenosis with percutaneous full-endoscopic surgery is still challenging, especially for elderly patients with multiple comorbidities and complex pathologic factors. The aim of this study was to introduce percutaneous full-endoscopic lumbar foraminoplasty and decompression using a visualization reamer in elderly patients with lateral recess and foraminal stenosis and evaluate efficacy and safety.

Radiological Characteristics and Surgical Outcome of Patients with Long Ossification of the Posterior Longitudinal Ligament Resulting in Ossified Lesions in the Upper Cervical Spine.

Objective: Designing surgical strategies for ossified lesions in the upper cervical spine is challenging owing to the complex anatomic structures. The present study aimed to clarify the prevalence of ossified lesions in the upper cervical spine in patients with ossification in the posterior longitudinal ligament and illustrate the clinical features, radiological findings, and surgical outcomes of this abnormality.

Methods: Demographic and clinical data were collected for all patients preoperatively and included age, gender, body mass index, alcohol and tobacco use, history of diabetes, visual analog score, and Japanese Orthopaedic Association score.
