Establishment of Scoring to Predict Severe Complication After Pyogenic Spondylodiscitis Surgery.

Study Design: Retrospective cohort study using prospective database.

Objective: This study aimed to establish a risk-scoring system for predicting severe complications after pyogenic spondylodiscitis surgery.

Summary Of Background Data: Pyogenic spondylodiscitis surgery can cause severe complications.

Usefulness of Novel Image-Enhanced Endoscopy for Predicting Maintenance of Clinical Remission in Ulcerative Colitis.

Purpose: The performance of endoscopic evaluation of ulcerative colitis (UC) using conventional scoring, including Mayo endoscopic subscore (MES) and ulcerative colitis endoscopic index of severity (UCEIS), is not satisfactory. Recently, the usefulness of novel image-enhanced endoscopy (IEE) such as texture and color enhancement imaging (TXI) and red dichromatic imaging (RDI) has been reported in the endoscopic evaluation of UC. We evaluated the performance of IEEs in UC, particularly focusing on the correlation with MES and UCEIS, and prediction of relapse.

Impact of Spinal Instrumentation on Early Postoperative Inflammatory Markers: A Comparative Analysis in the Same Patient Cohort with or without Instrumentation.

Backgrounds: Postoperative inflammatory parameters are important markers of surgical site infection. Some authors have reported that spine surgery with instrumentation elevates CRP levels more than that without instrumentation does. However, those studies compared early postoperative inflammatory markers with or without instrumentation in different patients, although CRP levels vary widely among patients.

HIF1α Plays a Crucial Role in the Development of TFE3-Rearranged Renal Cell Carcinoma by Orchestrating a Metabolic Shift Toward Fatty Acid Synthesis.

Tumor development often requires cellular adaptation to a unique, high metabolic state; however, the molecular mechanisms that drive such metabolic changes in TFE3-rearranged renal cell carcinoma (TFE3-RCC) remain poorly understood. TFE3-RCC, a rare subtype of RCC, is defined by the formation of chimeric proteins involving the transcription factor TFE3. In this study, we analyzed cell lines and genetically engineered mice, demonstrating that the expression of the chimeric protein PRCC-TFE3 induced a hypoxia-related signature by transcriptionally upregulating HIF1α and HIF2α.

Nanoclay gels attenuate BMP2-associated inflammation and promote chondrogenesis to enhance BMP2-spinal fusion.

Bone morphogenetic protein 2 (BMP2) is clinically applied for treating intractable fractures and promoting spinal fusion because of its osteogenic potency. However, adverse effects following the release of supraphysiological doses of BMP2 from collagen carriers are widely reported. Nanoclay gel (NC) is attracting attention as a biomaterial, given the potential for localized efficacy of administered agents.
