Bidirectional Longitudinal Association between Back Pain and Loneliness in Later Life: Evidence from English Longitudinal Study of Ageing.

Background: This study examined the bidirectional and temporal-ordinal relationship between loneliness and back pain.

Methods: Data from 7,730 participants in waves 6 (2012-2013), 7 (2014-2015), and 8 (2016-2017) of the national English Longitudinal Study of Ageing were analyzed. Back pain was graded on a scale of 0-10 (0, no discomfort; 10, unbearable pain).

MRI Grading Scale Predicts Ambulatory Function After Radiotherapy for Metastatic Spinal Cord Compression: A Prospective Single-Institution Observational Study.

Introduction: Although magnetic resonance imaging (MRI) is an important modality for the diagnosis of metastatic spinal cord compression (MSCC), there are only a few reports on MSCC findings and symptoms after radiotherapy. We aimed to reveal the factors related to ambulatory function after treatment, including the MRI findings, in a prospective observational study.

Methods: Patients with suspected MSCC who were treated with radiotherapy were included in this study.

Effect of Early Rehabilitation Treatment on Activities of Daily Living in Patients Receiving Conservative Treatment for Vertebral Compression Fracture.

Objectives: : Vertebral compression fractures are common among older people. Currently, knowledge of the effects of early rehabilitation treatment on the recovery of activities of daily living (ADL) in older patients who receive conservative treatment for these fractures is limited. Using the instrumental variable (IV) method, we examined the effects on ADL at discharge of a delay in initiating rehabilitation treatment.

Mid- to Long-Term Outcomes After Resection of Thoracic Dumbbell Tumors Managed by Laminectomy and Unilateral Total Facetectomy Without Instrumented Fusion.

Study Design: Retrospective multicenter study.

Objective: To evaluate mid- to long-term surgical outcomes of thoracic dumbbell tumors managed by laminectomy and unilateral total facetectomy without instrumented fusion.

Methods: A total of 15 patients with thoracic dumbbell tumors who underwent primary resection by laminectomy and unilateral total facetectomy without spinal instrumented fusion between 2000 and 2015 were reviewed.

Immunohistochemical Analysis of Inflammatory Rheumatoid Synovial Tissues Using Anti-Human Podoplanin Monoclonal Antibody Panel.

Podoplanin (PDPN) is a transmembrane sialoglycoprotein, which is expressed in several normal tissues and malignant tumors. Although PDPN expression in rheumatoid arthritis (RA) has been reported, the role of PDPN in RA and other arthritic conditions has not been fully elucidated. In this study, we examined PDPN expression in inflammatory synovial tissues using an anti-human PDPN (hPDPN) monoclonal antibody (mAb) panel to select the most useful one for evaluation of synovitis.

Comparison of the Effects of Osteochondral Autograft Transplantation With Platelet-Rich Plasma or Platelet-Rich Fibrin on Osteochondral Defects in a Rabbit Model.

Background: Although osteochondral autograft transplantation (OAT) provides satisfactory outcomes for osteochondral defects, for large defects OAT is often inadequate because of graft availability. Osteochondral allograft transplantation is an alternative treatment for large defects, but this approach is limited by graft storage constraints and carries disease transmission risks. Platelet-rich fibrin (PRF) is a second-generation platelet concentrate, and its positive effect on articular cartilage has been reported.
