Article Synopsis
  • A study was conducted to improve the differentiation between tumor recurrence and pseudoprogression (PsP) in high-grade glioma patients after surgery, focusing on radiomics analysis of tumor and surrounding areas.
  • The researchers extracted a total of 1316 features from MRI and ADC maps, using advanced algorithms to select optimal features for creating predictive models.
  • The combined analysis of intratumoral and peritumoral features showed significant effectiveness, achieving higher diagnostic performance compared to single-model approaches, with strong AUC values indicating accuracy in distinguishing between recurrence and PsP.

Aims: The dysregulation of TGF-β signaling is a crucial pathophysiological process in tumorigenesis and progression. LncRNAs have diverse biological functions and are significant participants in the regulation of tumor signaling pathways. However, the clinical value of lncRNAs related to TGF-β signaling in glioma is currently unclear.

Background: Lung adenocarcinoma (LUAD), a subtype of non-small cell lung cancer (NSCLC), causes high mortality around the world. Previous studies have suggested that the metabolic pattern of tumor is associated with tumor response to immunotherapy and patient's survival outcome. Yet, this relationship in LUAD is still unknown.

Background: Patients diagnosed with schizophrenia were found having lower risks to develop cancers, including glioma. Based on this epidemiology, we hypothesized that there were gene profiles playing opposite roles in pathogenesis of schizophrenia and glioma.

Methods: Based on GEO datasets and TCGA, key genes of schizophrenia genes on the opposite development of glioma were screened by different expressed genes (DEGs) screening, weighted gene coexpression network analysis (WGCNA), disease-specific survival (DSS), and glioma grading and verified by gene set enrichment analysis (GSEA).

Because the study population with gliosarcoma (GSM) is limited, the understanding of this disease is insufficient. In this study, the authors aimed to determine the clinical characteristics and independent prognostic factors influencing the prognosis of GSM patients and to develop a nomogram to predict the prognosis of GSM patients after craniotomy. A total of 498 patients diagnosed with primary GSM between 2004 and 2015 were extracted from the 18 Registries Research Data of the Surveillance, Epidemiology, and End Results (SEER) database.

Background: Outcomes of coiling embolization versus clipping for patients with high-grade aneurysmal subarachnoid hemorrhage (aSAH) have not been previously compared. We reviewed current evidence regarding the safety and efficacy of clipping versus coiling for high-grade aSAH.

Methods: We conducted a meta-analysis of studies that compared clipping with coiling in patients with high-grade aSAH published from January 1999 to February 2016 in Medline, Embase, and Cochrane databases based on PRISMA inclusion and exclusion criteria.

Objective: To investigate the discrepancy of anorectal function in patients of Parkinson's disease (PD) with constipation and functional constipation (FC).

Methods: Fifteen consecutive male PD patients with constipation and 45 male FC patients were recruited for the study. All subjects underwent colonoscopy or barium enema in order to exclude organic colon diseases.

Background: To compare the characteristics between 22-channel water-perfusion manometry (WPM) and solid-state manometry (SSM) with 36 sensors of the pressure measurements, as well as patients' discomfort indices in nose and pharynx, the preparation and operation time of the manometry.

Methods: 12 volunteers were included in the study. Each of the volunteers underwent esophageal manometry by both 22-channel water-perfusion catheter (WPC) and solid-state catheter (SSC) with 36 sensors in random order, and separated by 30 min.

Objective: To compare the diagnostic values of GerdQ questionnaire, 24-h pH monitoring and 24-h impedance-pH monitoring for gastroesophageal reflux disease (GERD) and to analyze the reflux patterns of Barrett's esophagus (BE), reflux esophagitis (RE) and non-erosive disease (NERD).

Methods: From June 1, 2009 to September 30, 2010, 205 GERD patients were included according to the Montreal consensus. All were surveyed by a GerdQ questionnaire and underwent 24-h impedance-pH monitoring.
