Meta Analysis
Increased risk of vertebral fracture in patients with rheumatoid arthritis: A meta-analysis.
The relationship between rheumatoid arthritis and risk of vertebral fracture has been reported by several observational studies. However, there is no higher-level evidence study, such as meta-analysis, that has investigated the relationship, and its mechanisms are not yet fully clear. This meta-analysis aimed to provide a summary of an observational study of the relationship between rheumatoid arthritis and the risk of vertebral fractures. ⋯ Subgroup analysis by study design showed that the pooled RRs for cohort studies, nested case-control studies, and case-control studies were 2.31 (95% CI 1.95-2.67, I = 4.8%, P for heterogeneity = 0.31), 1.89 (95% CI 1.01-2.77, I = 72.1%, P for heterogeneity = 0.06), and 2.62 (95% CI 2.04-3.91, I = 26.1%, P for heterogeneity = 0.26), respectively. Based on our meta-analysis, rheumatoid arthritis should be regarded as an independent risk factor of vertebral fracture. Further studies are needed to institute prevention and treatment strategies.

Review Case Reports
Prenatal diagnosis and genetic discoveries of an intracranial mixed neuronal-glial tumor: A case report and literature review.
Congenital intracranial tumors as a group are quite rare, representing only 0.5% to 1.5% of all pediatric brain neoplasms. ⋯ Prenatal detection of mixed neuronal-glial tumor is very rare. Ultrasound is of critical importance to detect the intracranial tumors, and MRI can give us some detailed information about the tumors. However, the precise histologic type was depended on the pathological examination. CMA should be necessary for the fetuses with congenital intracranial tumors, especially when the fetal chromosomal karyotype analysis is normal.

Pituitary carcinoma (PC) is a rare type of malignant intracranial neoplasm defined as distant metastasis of pituitary adenoma (PA). Although PC incidence is low because only 0.1% to 0.2% of PAs ultimately develop into PCs, the prognosis is poor and 66% of patients die within the first year. Existing therapeutic measures, including surgical removal, chemotherapy, and radiotherapy, have limited effectiveness. The lack of efficacy of current treatments is largely caused by the limited understanding of the molecular pathogenesis of PA and the malignant transformation to PC. Therefore, the aim of this systematic review was to summarize published research regarding gene and protein expression in PC to clarify the molecular mechanisms underlying PC genesis and development and identify new candidate diagnostic biomarkers and therapeutic targets for potential use in personalized treatment of PC. ⋯ Previous studies demonstrated that many genes promote PC malignant transformation, angiogenesis, invasion, metastasis, and recurrence. Although most of these genes and proteins have not been fully analyzed with regard to their downstream mechanisms or potential diagnostic and therapeutic application, they have the potential to become candidate PC biomarkers and/or molecular targets for guiding personalized treatment. Modern advanced technologies should be utilized in future research to identify more candidate genes for PC pathogenesis, as precisely targeted gene therapies against PC are urgently required.

Do-Not-Resuscitate (DNR) and hospice care are not only applied to cancer patients but also to patients with noncancer progressive illness. However, the trends of DNR consent and hospice utilization are not well explored for noncancer patients. This study aimed to explore the trends of DNR consent and hospice care utilization among noncancer decedents in a tertiary hospital in Taiwan. ⋯ There were increased trends of DNR consent in patients with major noncancer diagnoses, and increased hospice care utilization in patients diagnosed with lung diseases and renal failure from 2010 to 2014. However, the hospice care utilization could be improved. Further study to evaluate factors associated hospice care to improve the utilization is suggested.

Observational Study
Long-term outcomes of percutaneous radiofrequency thermocoagulation for glossopharyngeal neuralgia: A retrospective observational study.
The aim of this study was to investigate the long-term results of computed tomography (CT)-guided percutaneous radiofrequency thermocoagulation (PRT) for glossopharyngeal neuralgia (GPN). A retrospective review of medical records for patients with GPN who were treated with CT-guided PRT between 2003 and 2014 was performed to investigate baseline characteristics and immediate outcomes during the hospitalization. Long-term pain relief outcomes and complications were obtained via telephone survey. ⋯ Postprocedure complication included dysesthesias, dysphagia, and diminished gag reflex. No mortality was observed during or after PRT procedures. This study indicates that CT-guided PRT is a safe and effective method for patients with GPN and should be considered as an alternative treatment for these patients.
