Nomogram Models for Predicting Risk and Prognosis of Newly Diagnosed Ovarian Cancer Patients with Liver Metastases - A Large Population-Based Real-World Study.

Previous studies about liver metastases (LM) in newly diagnosed ovarian cancer (NDOC) patients based on Surveillance, Epidemiology, and End Results (SEER) program disregarded selection bias of missing data. We identified Data of NDOC patients from SEER between 2010 and 2016, presented a comprehensive description of this dataset, and limited possible biases due to missing data by applying multiple imputation (MI). We determined predictive factors for underlying LM development in NDOC patients and evaluated prognostic factors in NDOC patients with LM (OCLM).

Sarcopenia predicts an adverse prognosis in patients with combined hepatocellular carcinoma and cholangiocarcinoma after surgery.

Background: The prognostic value of sarcopenia in combined hepatocellular carcinoma and cholangiocarcinoma (cHCC-CC) patients after surgery has not been evaluated, while the efficacy of the available tumor stage for cHCC-CC remains controversial.

Methods: All consecutive cHCC-CC patients after surgery were retrieved. The patients were stratified by the sex-specific medians of the psoas muscle index into groups with or without sarcopenia.

The CT Image Changes in Ankylosing Spondylitis from Fracture to Andersson Lesions: A Case Report and Literature Review.

Background: Ankylosing spondylitis with Andersson lesions is not rare, but its potential pathogenesis and natural course remain unclear.

Case Description: We describe a case of CT image changes in ankylosing spondylitis from fracture to Andersson lesions. A 40-year-old man with a 23-year history of ankylosing spondylitis presented with acute back pain after a slight fall, and the CT showed a T12 fracture; the patient refused surgery for 12 months.

Reliability and application of the new morphological classification system for chronic symptomatic osteoporotic thoracolumbar fracture.

Background: We propose a new classification system for chronic symptomatic osteoporotic thoracolumbar fracture (CSOTF) based on fracture morphology. Research on CSOTF has increased in recent years; however, the lack of a standard classification system has resulted in inconvenient communication, research, and treatment. Previous CSOTF classification studies exhibit different symptoms, with none being widely accepted.

Incidence and Outcomes of C5 Palsy and Axial Pain After Open-Door Laminoplasty or Laminectomy and Fusion: A Meta-Analysis.

Objective: C5 palsy and axial pain are significant factors affecting the quality of life after posterior cervical surgery; however, there has been no clear and supportive conclusion on which method is more suitable in a certain case. As a result, we compare the clinical outcomes, complication rates, and anatomical changes between open-door laminoplasty (ODL) and laminectomy and fusion (LF) for cervical spondylotic myelopathy. This is a systematic literature review and meta-analysis.

Early versus delayed decompression for traumatic cervical spinal cord injury: application of the AOSpine subaxial cervical spinal injury classification system to guide surgical timing.

Purpose: Application of AOSpine subaxial cervical spine injury classification system to explore the optimal surgical decompression timing for different types of traumatic cervical spinal cord injury (CSCI).

Risk factors for conservative treatment failure in acute osteoporotic vertebral compression fractures (OVCFs).

Unlabelled: This study aimed to identify risk factors for failure of conservative treatment of acute OVCFs. The results showed age, BMD, BMI, mFI, and IVC were high-risk factors for failure of conservative treatment of acute OVCFs.

Purpose: This study aimed to identify risk factors for failure of conservative treatment of acute osteoporotic vertebral compression fractures (OVCFs).

Long-Segment or Bone Cement-Augmented Short-Segment Fixation for Kummell Disease with Neurologic Deficits? A Comparative Cohort Study.

Background: The standard treatment for Kummell disease with neurologic deficit remains controversial. Traditional posterior long-segment fixation (LSF) has been widely used, but the procedure results in significant trauma and carries the risk of multiple complications. Therefore, bone cement-augmented short-segment fixation (BCASSF) has been recommended for this condition.

The analysis of MSTMOVCF (Multi-segment thoracolumbar mild osteoporotic fractures surgery or conservative treatment) based on ASTLOF (the assessment system of thoracolumbar osteoporotic fracture).

To investigate the issue that conservative or surgical treatment for multi-segmental thoracolumbar mild osteoporotic vertebral compression fracture (MSTMOVCF) by applying the assessment system of thoracolumbar osteoporotic fracture (ASTLOF).

Methods: A single-center prospective cohort study was conducted to enroll patients with thoracic/thoracolumbar incomplete SCI from April 2013 to November 2016; they were divided into an early group (<24 hours after SCI) and a late group (24-72 hours after SCI). Each group was divided into A, B, C subgroups according to AOSICS.

Rare Hereditary Abnormal Bone Hyperplasia and Ossification of the Yellow Ligament Complicated by Thoracic Spinal Stenosis.

We report a rare case of familial inherited abnormal bone hyperplasia and ossification of the yellow ligament complicated by spinal stenosis. Complete reconstruction of stability and spinal cord decompression were achieved by posterior total laminectomy, fusion, and internal fixation. We cannot clearly describe the inheritance characteristics of the disease.

Radiological and clinical differences among three assisted technologies in pedicle screw fixation of adult degenerative scoliosis.

The purpose of this study was to compare the clinical and radiological differences among three advanced guided technologies in adult degenerative scoliosis. A total of 1012 pedicle screws were inserted in 83 patients using a spine robot (group A), 886 screws were implanted in 75 patients using a drill guide template (group B), and 1276 screws were inserted in 109 patients using CT-based navigation (group C). Screw positions were evaluated using postoperative CT scans according to the Gertzbein and Robbins classification.

Accuracy of a patient-specific template for pedicle screw placement compared with a conventional method: a meta-analysis.

Introduction: Accurate placement of pedicle screws in spine surgery is a challenge for surgeons. Patient-specific template techniques have the potential for improving the accuracy of screw placement. The target of this analysis was to investigate differences in terms of accuracy of pedicle screw insertion between patient-specific template assistance and the conventional free-hand method for reconstruction of spinal stability.

The aim of this study was to observe clinical and imaging outcomes of application of gelatin sponge impregnated with a mixture of 3 drugs to intraoperative nerve root block combined with robot-assisted minimally invasive transforaminal lumbar interbody fusion surgery in to treat adult degenerative lumbar scoliosis.

Methods: From January 2012 to November 2014, 108 patients with adult degenerative lumbar scoliosis were treated with robot-assisted minimally invasive transforaminal lumbar interbody fusion surgery combined with intraoperative gelatin sponge impregnated with a mixture of 3 drugs.

Accuracy of Pedicle Screw Insertion Among 3 Image-Guided Navigation Systems: Systematic Review and Meta-Analysis.

Background: Many retrospective studies of pedicle screw placement have revealed that intraoperative navigation systems provide higher accuracy rates and safety than do free-hand techniques. The accuracy of various image-guided navigation systems has been studied; however, differences have not been well defined due to the lack of adequate evidence-based comparative studies.

Objective: A meta-analysis was conducted to focus on the variation in pedicle screw insertion among 3 navigation systems: a 3-dimensional fluoroscopy-based navigation system (3D FluoroNav), a 2-dimensional fluoroscopy-based navigation system (2D FluoroNav), and a conventional computed tomography navigation system (CT Nav).

IFN-γ secretion in gut of Ob/Ob mice after vertical sleeve gastrectomy and its function in weight loss mechanism.

Vertical sleeve gastrectomy (VSG) is becoming more and more popular among the world. Despite its dramatic efficacy, however, the mechanism of VSG remains largely undetermined. This study aimed to test interferon (IFN)-γ secretion n of mesenteric lymph nodes in obese mice (ob/ob mice), a model of VSG, and its relationship with farnesoid X receptor (FXR) expression in the liver and small intestine, and to investigate the weight loss mechanism of VSG.
