The purpose of this study was to evaluate the potential of chitosan units released during natural degradation of the polymer to activate the immune system against T. spiralis infection. High molecular weight chitosan was injected intraperitoneally into C57BL/6 mice. Flow cytometry and cytokine concentration, measured by ELISA, were used to characterize peritoneal cell populations during T. spiralis infection. The strong chemo-attractive properties of chitosan caused considerable infiltration into the peritoneal cavity of CD11b⁺ cells, with reduced expression of MHC class II, CD80, CD86, Dectin-1 or CD23 receptors in comparison to T...

BACKGROUND: We explored host-related factors associated with the site of tuberculosis (TB) disease using variables routinely collected by the 31 EU/EEA countries for national surveillance. METHODS: Logistic regression models were fitted to case-based surveillance data reported to the European Centre for Disease Prevention and Control for TB cases notified from 2003 to 2014. Missing data on HIV infection and on susceptibility to isoniazid and rifampicin for many patients precluded the inclusion of these variables in the analysis...

The global burden of chronic kidney disease (CKD) has increased substantially in recent years, partly attributed to the global epidemic of diabetes mellitus. In many countries including China, glomerulonephritis was the most common cause of end stage renal disease (ESRD). The mortality rate of dialysis patients can be as high as patients with colon, breast and prostate cancers. CKD has important socio-economic impact on the healthcare system and society. Increasing awareness and early detection of CKD cannot be overemphasized...

Although gemcitabine is an effective chemotherapeutic for pancreatic cancer, severe side effects often accompany its use. Since we have discovered that locally administered C1B domain peptides effectively control tumor growth without any side effects, the efficacy of co-treatment with this peptide and a low dose of gemcitabine on the growth of pancreatic cancer was examined. Two- and three-dimensional cell culture studies clarified that a co-treatment with C1B5 peptide and gemcitabine significantly attenuated growth of PAN02 mouse and PANC-1 human pancreatic cancer cells in 2D and 3D cultures...

REVIEW
François Audenet, John P Sfakianos
Robot-assisted radical cystectomy (RARC) has seen remarkable growth in the last decade. Despite a low level of evidence, numerous publications reporting on outcomes after RARC are now available. While definitive data on the long-term oncologic safety and efficacy of this technique are still lacking, similar oncological and functional outcomes compared to open radical cystectomy (ORC) have been reported. Several studies have also reported on atypical recurrences after RARC, including peritoneal carcinomatosis, extra-pelvic lymph node metastasis and port-site metastasis...

Icodextrin is a starch derivative used for preparing solutions of peritoneal dialysis. Unfortunately, peptidoglycans (PGN) and lipopolysaccharides (LPS) have been reported to contaminate certain icodextrin batches and to contribute to the development of sterile peritonitis. The decision of selecting or rejecting icodextrin batches is however difficult, because of limitations in the detection of these bacterial contaminants. Besides monocyte activation tests of cytokine release, a number of bio-assays using stably TLR-transfected cell lines have been developed...

BACKGROUND The incidence of incisional hernia following renal transplantation is 1.1% to 3.8%. The risk factors are immunosuppressive medications, impaired tissue quality, neuromuscular trauma due to the operation, and denervation. The incidence has been decreasing based on the shift from hockey-stick incision method to inguinal oblique incision method. The aim of this study was to minimize the development of incisional hernias due to renal transplantation. MATERIAL AND METHODS Twenty-four patients who underwent renal transplantation in 2015-2017 were retrospectively examined...

Ascites is a rare complication of multiple myeloma (MM); in most cases, the direct invasion of myeloma cells to the peritoneal cavity has been assumed to be the etiology because the effusion is usually exudative and contains a high proportion of myeloma cells. We herein report a case of MM with massive ascites containing only a small amount of myeloma cells. Instead, high levels of serum and ascitic VEGF were detected. This was suggested to be a potential mechanism underlying the development of ascites.

Arterial stiffness is an important risk factor for cardiovascular disease (CVD) in patients with end-stage renal failure. However, little is known about the factors that contribute to arterial rigidity in peritoneal dialysis (PD) patients. The aim of this study was to define the pattern and determinants of the longitudinal change in arterial stiffness after PD initiation.Arterial stiffening was estimated for 46 PD patients by using brachial-ankle pulse wave velocity (baPWV) and carotid intima-media thickness (cIMT)...

Objective: To investigate the tumor microenvironment of immune tolerance induced by glioma stem cells (GSC). Methods: Human GSC SU3 cells transfected with red fluorescent protein (SU3-RFP) gene were implanted into the brain, subcutis (armpit and foot), liver and abdominal cavity of transgenic green fluorescence protein (GFP) nude mice to establish RFP(+) /GFP(+) dual fluorescence solid tumor model. The re-cultured cells derived from implanted tumor tissues, SU3-RFP cells co-cultured with peritoneal fluid of transgenic GFP nude mice and malignant ascites of tumor-bearing mice were observed by fluorescence microscopy and real-time video image tracing to analyze the microenvironment of immune tolerance mediated by RFP(+) /GFP(+) implanted tumor...

BACKGROUND: Malnutrition is a significant problem in those undergoing peritoneal dialysis (PD). Factors such as gastrointestinal (GI) symptoms and the need for a fluid reduced diet can limit tolerance and thereby the efficacy of oral nutritional supplements to treat malnutrition. OBJECTIVES: To evaluate the acceptability and impact of two different forms of oral nutrition supplementation for 16 weeks on nutritional markers and quality of life of malnourished patients undergoing PD...

BACKGROUND: Maintenance peritoneal dialysis (PD) is the dialysis modality of choice for infants and young children. However, there are limited outcome data for those who undergo PD catheter insertion and initiate maintenance PD within the first year of life. METHODS: Using data from the Children's Hospital Association's Standardizing Care to Improve Outcomes in Pediatric End Stage Renal Disease (ESRD) Collaborative (SCOPE), we examined peritonitis rates and patient survival in 156 infants from 29 North American pediatric dialysis centers who had a chronic PD catheter placed prior to their first birthday...

Acid-base regulation is essential to maintain homeostasis in humans. Carbonic acid/bicarbonate (H2CO3/HCO3(-)) couple is the most predominant extracellular buffer to keep plasma pH within a physiological range. The ability to (re)generate such a buffer is a key milestone that necessitates to understand a precise physiology of both renal tubule and digestive tract. Here, we first reviewed renal and digestive cycles of bicarbonate in physiology. We also reviewed pathological findings where acid-base disequilibrium is involved and nutritional and/or alkali therapy could be necessary...
