Extensive neovascularization is a hallmark of glioblastoma (GBM). In addition to supplying oxygen and nutrients, vascular endothelial cells provide trophic support to GBM cells via paracrine signaling. Here we report that Endocan (ESM1), an endothelial-secreted proteoglycan, confers enhanced proliferative, migratory, and angiogenic properties to GBM cells and regulates their spatial identity.

Introduction: Unsedated peroral endoscopy, including ultrathin endoscopy (UE) and conventional endoscopy (CE), is feasible in clinical practice but requires improved endoscopic operability and patient tolerance. Currently, the impact of the breathing method on these factors remains unclear. We conducted the first randomized controlled trial comparing oral breathing (OB) and nasal breathing (NB) during both UE and CE to assess their influence.

Objective: Epicardial adipose tissue (EAT) is an important imaging indicator of cardiovascular risk. EAT volume is usually measured using electrocardiogram (ECG) gating. However, there are concerns regarding the influence of motion artifacts when measuring EAT volume on non-ECG-gated plain chest computed tomography (CT) images.

Gastric adenocarcinoma of the fundic gland type (GA-FG) is characterized by an elevated lesion with vessel dilation exhibiting branching architecture (DVBA). However, this feature is also found in fundic gland polyps (FGPs), posing a challenge in their differentiation. In this study, we aimed to investigate the clinicopathological features of gastric elevated lesions with DVBA and assess the efficacy of the white ring sign (WRS) as a novel marker for distinguishing between FGPs and GA-FGs.

Aim: We studied the effects of overhydration (OH), Kt/Vurea and β2-microglobulin (β2-MG) on coronary artery calcification and mortality in patients undergoing haemodialysis (HD).

Methods: The Agatston coronary artery calcium score (CACS), postdialysis body composition using bioimpedance analysis, single-pool Kt/Vurea and predialysis β2-MG at baseline were assessed and followed up for 3 years in patients undergoing HD. We performed logistic regression analyses for a CACS ≥400 and Cox proportional hazard analyses for all-cause and cardiovascular mortality.

Aim: The effects of iron on vascular calcification in rats and vascular smooth muscle cells were recently reported, but clinical studies on iron and vascular calcification are scant. We studied the associations of absolute iron deficiency, coronary artery calcification and mortality in patients with maintenance haemodialysis (MHD).

Methods: Transferrin saturation (TSAT), ferritin, mean corpuscular haemoglobin (MCH) and Agatston coronary artery calcium score (CACS) were studied at baseline in MHD patients and followed up for 3 years.

Background: Arteriovenous fistula (AVF) patency is important for patients undergoing hemodialysis. The association between early AVF failure and the prognosis, including all-cause mortality and major adverse cardiovascular events (MACE), has not been fully investigated. The present study was performed to investigate the association between early AVF failure and 3-year mortality, cardiovascular disease (CVD) mortality, and MACE.

Article Synopsis
  • An unusual case of nephrotic syndrome following multiple bee and wasp stings in a 79-year-old woman is reported, leading to the diagnosis of membranous nephropathy.
  • After being stung seven times, the patient experienced significant weight gain, edema, and specific urine and serum test results indicative of nephrotic syndrome.
  • A kidney biopsy confirmed stage I membranous nephropathy, and the patient's condition improved with treatment, marking this as the first documented instance linking Hymenoptera stings to this type of kidney disease.

Article Synopsis
  • This observational study evaluated the outcomes of peritoneal dialysis (PD) catheter placement in Japan to see if they align with the International Society for Peritoneal Dialysis guidelines.
  • The study tracked 409 adult patients who underwent PD catheter placement, finding a low rate of catheter patency failure (6.2%) and a technique failure rate of 15.3% after 12 months.
  • Factors influencing technique failure included lower serum albumin levels and type of catheter used, while diabetes increased the risk of perioperative infections; however, overall complications met ISPD audit standards.

Aim: β2-Microglobulin (β2-MG) and α1-microglobulin (α1-MG) have molecular weights of 11,800 and 33,000 Da, respectively. We studied the α1-MG and β2-MG reduction ratios (RRs) and survival in patients on predilution online haemodiafiltration (Pre-OL-HDF).

Methods: Participants were 247 Pre-OL-HDF patients.

Nasal breathing is superior to oral breathing when performing and undergoing transnasal endoscopy: a randomized trial.

Endoscopy

March 2023

Gastroenterology and Endoscopy, Division of Metabolism and Biosystemic Science, Gastroenterology, and Hematology/Oncology, Department of Medicine, Asahikawa Medical University, Asahikawa, Hokkaido, Japan.

BACKGROUND : Transnasal endoscopy presents a technical difficulty when inserting the flexible endoscope. It is unclear whether a particular breathing method is useful for transnasal endoscopy. Therefore, we conducted a prospective randomized controlled trial to compare endoscopic operability and patient tolerance between patients assigned to nasal breathing or oral breathing groups.

Article Synopsis
  • - The study investigated if combining the geriatric nutritional risk index (GNRI) and modified creatinine index (mCI) could provide better predictions for mortality in chronic hemodialysis patients, analyzing data from 499 individuals over five years.
  • - Patients were divided into four groups based on their GNRI and mCI scores, with significant differences in survival outcomes noted, particularly showing that groups with low GNRI and low mCI had worse outcomes.
  • - Results indicated that using both GNRI and mCI together is more effective for predicting mortality compared to using either index alone, helping differentiate between patients' health statuses more accurately.

Background: A few previous clinical studies have shown that chloride (Cl) contributes to the progression and development of hypertension or proteinuria. Therefore, we aimed to determine whether hyperchloremia is associated with hypertension or proteinuria in patients with chronic kidney disease (CKD) and to define the relationships between the reduction in serum Cl concentration associated with CKD treatment and improvements in hypertension and/or proteinuria.

Methods: We performed a retrospective observational study of new or referred patients with CKD who had hyperchloremia, moderate proteinuria, renal dysfunction, and hypertension.

Introduction: We investigated the association between intradialytic hypotension (IDH) and coronary artery calcification and their effects on mortality in hemodialysis (HD) patients.

Methods: Consecutive patients undergoing maintenance HD were enrolled. The study timeline included the baseline (day 1), exposure assessment (day 1-day 22), and outcome assessment (day 23-3 years) periods.

Article Synopsis
  • - The CHA2DS2-VASc score, commonly used to predict stroke in atrial fibrillation patients, may also indicate the risk of cardiovascular disease and mortality in patients undergoing hemodialysis.
  • - A study analyzed 557 hemodialysis patients, finding that a higher CHA2DS2-VASc score was associated with increased risks of 3-year all-cause mortality and cardiovascular death.
  • - Key factors influencing mortality included serum albumin, creatinine levels, and the CHA2DS2-VASc score, with intermediate and high score patients facing significantly higher mortality risks.

Background: The objective of this multicenter, prospective observational study was to determine the factors related to patency rates after construction of vascular access (VA) and the first percutaneous transluminal angioplasty (PTA).

Methods: The 24-month primary and secondary patency rates after construction of a radiocephalic arteriovenous fistula (RC-AVF) and arteriovenous graft (AVG) were evaluated using the Kaplan-Meier method and log-rank test. The 12-month post-PTA patency rate was also investigated.
