Herein we report nine cases of carotid endarterectomy in which we used a cold atmospheric helium plasma device (J-Plasma; Apyx Medical Corporation, Clearwater, Fla). Although clinical reports are limited, experimental data indicate that this technology could be used for dissection and coagulation during surgery, yielding limited adjacent tissue damage. As a result, it could be extremely useful in procedures like carotid endarterectomy that necessitate careful dissection and coagulation with limited damage of adjacent neurovascular structures. © 2020 The Author(s).Median arcuate ligament syndrome is a rare and poorly understood condition that can have a significant impact on the quality of life of patients. Diagnosis is often difficult and delayed because of the need to exclude other pathologic processes. Treatment strategies traditionally involve open or laparoscopic division of the median arcuate ligament, with or without vascular reconstruction. This report portrays a case of median arcuate ligament syndrome with compression of two visceral arteries and distal embolic complications. A novel hybrid technique is described using intravascular ultrasound technology to aid in laparoscopic median arcuate ligament division. This allowed real-time intravascular visualization of the compressive segment, guided release of the ligament fibers, and demonstrated confirmation of decompression. © 2020 The Author(s).Retroperitoneal hematoma is a potential complication of femoral venous access that rarely leads to bilateral ureteral obstruction. We present the case of a 73-year-old woman who underwent an ablation procedure for atrial fibrillation complicated by laceration of an aberrant obturator artery during femoral venous cannulation, leading to a compressive retroperitoneal hematoma, bilateral ureteral obstruction, acute renal failure, and renal forniceal rupture. The patient was successfully treated with embolization of the inferior epigastric artery and aberrant obturator artery, hematoma evacuation, and ureteral stent placement. This case illustrates a rare complication of arterial laceration during femoral venous access without ultrasound guidance. © 2020 The Authors.Chimney/snorkel endovascular aneurysm repair (Ch-EVAR) enables the minimally invasive treatment of abdominal aortic aneurysm in anatomically challenging and high-risk surgical cases. Here, we present the case of a 77-year-old man with an abdominal aortic aneurysm associated with crossed fused renal ectopia and an ectopic renal artery arising directly from the aneurysm sac. After successful implementation of Ch-EVAR, computed tomography angiography at 18 months revealed no endoleaks, patency of the parallel graft, and normal renal vascularization and function. This report underscores the feasibility of Ch-EVAR in a case with high anatomic complexity. © 2020 The Authors.Pseudoaneurysm development after carotid endarterectomy is a rare occurrence. Even rarer is pseudoaneurysm formation associated with a distal carotid artery stenosis. We report the case of stent grafting of a carotid artery pseudoaneurysm and tandem high-grade distal stenosis through a transcarotid approach with active flow reversal. No reported cases of a transcarotid artery approach to address a carotid artery aneurysm with tandem stenosis were found in the literature. We show that it may be a safe alternative to a transfemoral artery approach or open surgery. © 2020 The Authors.A 59-year-old woman presented with advanced, symptomatic carotid artery stenosis in the setting of severe medical comorbidities including coronary artery disease, congestive heart failure with recent admission for exacerbation, and diabetes mellitus. She underwent awake transcarotid artery revascularization because of her medically high-risk status. Postoperatively, she was noted to have developed pneumothorax, pneumomediastinum, and dysphonia, thought to be secondary to entrained air during the course of low neck dissection for carotid artery exposure in the setting of partial airway obstruction and high negative intrathoracic pressures during the procedure. After conservative treatment, she ultimately enjoyed complete clinical resolution. This case demonstrates an unusual complication of awake transcarotid artery revascularization.Epstein-Barr virus (EBV) is a ubiquitous human herpes virus, which is implicated in cancer and various autoimmune diseases. This study profiles non-micro small non-coding RNA expression changes induced by latent EBV infection. Using small RNA-Seq, 346 non-micro small RNAs were identified as being significantly differentially expressed between EBV(+) BJAB-B1 and EBV(-) BJAB cell lines. Select small RNA expression changes were experimentally validated in the BJAB-B1 cell line as well as the EBV-infected Raji and Jijoye cell lines. This latter analysis recapitulated the previously identified induction of vault RNA1, while also finding novel evidence for the deregulation of several tRNAs and a snoRNA. © 2020 Production and hosting by Elsevier B.V. on behalf of KeAi Communications Co., Ltd.Streptococcus pneumonia is one of the leading causes of mobility and mortality in children under 6 years and the elderly especially in developing countries in which Ghana, the study area is not an exception.In this paper, a model of the spread and control of bacterial pneumonia that include symptomatic carriers, asymptomatic carriers and vaccination is formulated and analyzed to determine the effect of the vaccination intervention.Analysis of the system show that the disease free equilibrium is stable if and only if the basic reproductive number R 0 less then 1 . For R 0 ≥ 1 , the endemic equilibrium is globally stable and the disease persist. Numerical simulation on the system show that with effective vaccine intervention pneumonia infection can be eradicated in the long term. © 2019 The Authors.Introduction Anion exchanger 1 (AE1) (SLC4A1 gene product) is a membrane protein expressed in both kidney and red blood cells (RBCs) it exchanges extracellular bicarbonate (HCO3 -) for intracellular chloride (Cl-) and participates in acid-base homeostasis. AE1 mutations in kidney α-intercalated cells can lead to distal renal tubular acidosis (dRTA). In RBC, AE1 (known as band 3) is also implicated in membrane stability deletions can cause South Asian ovalocytosis (SAO). Methods We retrospectively collected clinical and biological data from patients harboring dRTA due to a SLC4A1 mutation and analyzed HCO3 - and Cl- transports (by stopped-flow spectrophotometry) and expression (by flow cytometry, fluorescence activated cell sorting, and Coomassie blue staining) in RBCs, as well as RBC membrane stability (ektacytometry). Results Fifteen patients were included. All experience nephrolithiasis and/or nephrocalcinosis, 2 had SAO and dRTA (dRTA SAO+), 13 dominant dRTA (dRTA SAO-). The latter did not exert specific RBC membrane anomalies. Both HCO3 - and Cl- transports were lower in patients with dRTA SAO+ than in those with dRTA SAO- or controls. Using 3 different extracellular probes, we report a decreased expression (by 52%, P  less then 0.05) in dRTA SAO+ patients by fluorescence activated cell sorting, whereas total amount of protein was not affected. Conclusion Band 3 transport function and expression in RBCs from dRTA SAO- patients is normal. However, in SAO RBCs, impaired conformation of AE1/band 3 corresponds to an impaired function. Thus, the driver of acid-base defect during dominant dRTA is probably an impaired membrane expression. © 2020 International Society of Nephrology.

More information on the phenotype and prognosis is needed to improve clinical diagnostics and treatment. Methods We included all Norwegian patients with chronic kidney disease (CKD) referred for kidney biopsy between 1988 and 2012 whose clinical presentation was consistent with, but not primarily suspicious for, hypertensive nephrosclerosis (n = 4920); follow-up continued until 2013. Results A total of 918 patients (19%) had biopsy-verified hypertensive nephrosclerosis (i.e., arterionephrosclerosis). Their most common biopsy indications were proteinuria (57%), low estimated glomerular filtration rate (eGFR) (44%), hematuria (34%), or combinations of these indications. buy Vismodegib Multivariable logistic regression analysis revealed that arterionephrosclerosis was significantly associated with higher age, male sex, not having diabetes, higher blood pressure, lower proteinuria, and not having hematuria (P  0.1 for both), whereas patients with diabetic kidney disease had a 2-fold higher risk (P  less then 0.001 for both). Conclusion Arterionephrosclerosis is a high-risk disease, often with an atypical phenotype with proteinuria and hematuria contributing to low accuracy for current clinical criteria for hypertensive nephrosclerosis. © 2019 International Society of Nephrology. Published by Elsevier Inc.Introduction Patients with phospholipase A2 receptor (PLA2R)-associated membranous nephropathy and stage 4 or 5 chronic kidney disease are at high risk of end-stage kidney disease. In recent years, rituximab (RTX) emerged as a safe and efficient treatment for patients with PLA2R-associated membranous nephropathy. Whether its use is also appropriate in patients with an estimated glomerular filtration rate  less then 30 ml/min per 1.73 m2 has not been investigated. Methods We retrospectively reviewed characteristics and outcome of 13 patients with PLA2R-associated membranous nephropathy and stage 4 or 5 chronic kidney disease who received a total of 14 consecutive RTX treatments from January 2012 to March 2018. The treatment regimen consisted of either 2 weekly infusions of 375 mg/m2 or 2 RTX infusions of 1 g/d two weeks apart. When needed, the regimen was repeated to achieve immunological remission. Results The mean estimated glomerular filtration rate, serum albumin level, and urinary protein level at the first RTX infusion were 18 ± 7 ml/min per 1.73 m2, 25.2 ± 5.4 g/l, and 13.2 ± 7.5 g/d, respectively, with all patients being tested positive for serum PLA2R antibodies. Ten treatment courses led to an increase in estimated glomerular filtration rate and remission of nephrotic syndrome after a median follow-up of 40.8 months (interquartile range, 14.8-46.8). Conversely, 4 RTX treatments were unsuccessful, with patients requiring chronic hemodialysis within 1 year. The urinary albumin-to-protein ratio before treatment was predictive of renal response. Immunological remission occurred after 11 treatment courses and was associated with clinical response in 10 of 11 patients. Three patients experienced severe adverse events. Conclusion RTX seems effective and reasonably safe in PLA2R-associated membranous nephropathy with stage 4 or 5 chronic kidney disease. Immunological remission is associated with a good clinical outcome. © 2019 International Society of Nephrology.

We sought to characterize relationships between inflammatory biomarkers and depressive symptoms in patients with chronic kidney disease and end-stage kidney disease. Methods A systematic literature search was conducted by 2 authors up to March 19, 2019, for studies of patients with chronic kidney disease or end-stage kidney disease evaluating circulating inflammatory biomarkers associated with depression of chronic disease albumin, C-reactive protein (CRP), high-sensitivity CRP, interleukin-6 (IL-6), tumor necrosis factor-α, and interleukin-1. Standardized mean differences in biomarkers between individuals with and without depression were computed and analyzed using mixed effects models. Correlations between biomarkers and the severity of depressive symptoms were computed. Results Thirty-four studies (5652 participants) compared biomarkers between depressed and nondepressed individuals. Individuals with depression had lower albumin levels (standardized mean difference, -0.
