End-stage renal disease, the last and most severe stage of chronic kidney disease, represents a major and rising concern for countries in Latin America, driven in large part by aging populations and the near-epidemic rises in diabetes, obesity, and hypertension. This places a great clinical, economic, and social burden on the region's health systems. During the ISPOR 6th Latin America Conference held in Sao Paulo, Brazil, in September 2017, an educational forum debated on value-based decision making in the treatment of end-stage renal disease in Latin America...

In this work, we chose cartilage acellular matrix (CAM) as a promising antiadhesive material because CAM effectively inhibits the formation of blood vessels, and we used electrospinning to prepare antiadhesive barriers. Additionally, we synthesized N-hydroxysuccinimide (NHS)-poly(caprolactone-co-lactide-co-glycolide)-NHS (MP) copolymers (to tune degradation) as a cross-linking agent for CAM. This is the first report on the development of electrospun cross-linked (Cx) CAM/MP (CA/P) nanofiber (NF) (Cx-CA/P-NF) with a tunable degradation period as an antiadhesive barrier...

The amino acid transport system xc - is important for maintaining intracellular glutathione levels and extracellular redox balance. The main component of system xc - , xCT, is strongly induced by various stimuli, including oxidative stress and bacterial lipopolysaccharides (LPS) in macrophages. In the present study, we investigated the production of nitric oxide by LPS-stimulated mouse peritoneal macrophages isolated from both xCT-deficient and wild-type mice. After culturing macrophages in the presence of LPS for 24-48 h, nitrite levels in the medium of xCT-deficient macrophages were significantly decreased compared to that of wild-type cells...

BACKGROUND: Both peritoneal small solute transport and peritoneal protein clearance are closely linked to outcomes in peritoneal dialysis (PD) patients. However, the associated factors of these two components are not fully understood so far. This study aimed to investigate the association between a panel of systemic and peritoneal inflammatory and angiogenic factors and peritoneal solute transport properties. METHODS: Stable PD patients in PD center of Renji Hospital, School of Medicine, Shanghai Jiao Tong University were enrolled in present study...

B cell responses are regulated by antigen acquisition, processing, and presentation to helper T cells. These functions are thought to depend on contractile activity of non-muscle myosin IIa. Here, we show that B cell-specific deletion of the myosin IIa heavy chain reduced the numbers of bone marrow B cell precursors and splenic marginal zone, peritoneal B1b, and germinal center B cells. In addition, myosin IIa-deficient follicular B cells acquired an activated phenotype and were less efficient in chemokinesis and extraction of membrane-presented antigens...

INTRODUCTION: The systemic inflammatory response has been proven to have a prognostic value. There are two methods of assessing the systemic inflammatory response composite ratios (R) and cumulative scores (S). The aim of this study was to compare the prognostic value of ratios and scores in patients undergoing surgery for colon cancer. METHODS: Patients were identified prospectively in a single surgical unit. Preoperative neutrophil (N), lymphocyte (L), monocyte (M) and platelet (P) counts, CRP (C) and albumin (A) levels were recorded...

BACKGROUND: Polycystic kidney disease (PKD) is the most frequent hereditary cause of chronic kidney disease. Peritoneal dialysis (PD) is often avoided for patients with PKD because of the suspected risk of mechanical and infectious complications. Only a few studies have analyzed the outcome of PKD patients on PD with sometimes conflicting results. The purpose of this meta-analysis was to investigate outcomes of patients with PKD treated by PD. METHODS: A systematic review and meta-analysis were performed examining all studies which included "Polycystic kidney disease" and "Peritoneal dialysis" in their titles, excluding commentaries, letters to the authors and abstracts...

The controlled release of small molecular modulators of the immune response from hydrogel microspheres (MS) used for cell immobilization is an attractive approach to reduce pericapsular fibrotic overgrowth (PFO) after transplantation. Ketoprofen is a well-known non-steroidal anti-inflammatory drug involved in the early stage inflammation cascade. PEGylated derivatives of ketoprofen, presenting either ester or amide linkage to the drug, were synthesized and conjugated to the hydroxyl groups of sodium alginate (Na-alg)...

Kudzu ( Pueraria montana var. lobata (Willd.) Sanjappa & Pradeep) is a perennial leguminous vine, and its root and flower have been used for herbal medicine in Asia for a long time. Most dietary flavonoids are reported to be concentrated in its root, not in its aerial parts including leaves. In this study, we investigated whether kudzu leaf and its major constituent, robinin (kaempferol-3- O -robinoside-7- O -rhanmoside) possessed anti-inflammatory activity. To test this hypothesis, we used peritoneal macrophages isolated from BALB/c mice and stimulated the cells with lipopolysaccharide (LPS) or LPS plus interferon (IFN)-γ...

OBJECTIVE: Introduction: Nowadays operative treatment of corrosive esophageal strictures remains one of the difficult and unsolved problems in surgery. The level of postoperative complications such as anastomotic leak (develops in 7-30% of cases), infections, pneumonia, pleural empyema, mediastinitis, peritonitis, postoperative corrosive strictures is still rather high. The aim of our work was to improve the results of surgical treatment of patients with corrosive esophageal strictures by analyzing and refining on conservative therapy options as well as differentiated approach to each operative treatment method...

We report the first application of pressurized intraperitoneal aerosol chemotherapy (PIPAC) as a rescue therapy before palliative D2 gastrectomy combined with liver metastasectomy performed in a 49-year-old woman with peritoneal carcinomatosis who was primarily diagnosed with and underwent surgery for a Krukenberg tumor. The PIPAC procedure was performed with the use of cisplatin at 7.5 mg/m2 and doxorubicin at 1.5 mg/m2 for 30 min at 37 °C. Eight weeks after the PIPAC procedure, the patient underwent open classic D2 gastrectomy with the creation of a Roux-en-Y anastomosis (RNY) combined with liver metastasectomy...

Antibiotics with novel bactericidal mechanisms of action are urgently needed. The antibiotic acyldepsipeptide 4 (ADEP4) activates the ClpP protease and causes cells to self-digest. The effects of ADEP4 and ClpP activation have not been sufficiently characterized for the enterococci, which are important pathogens known for high levels of acquired and intrinsic antibiotic resistance. In the present study, ADEP4 was found to be potently active against both Enterococcus faecalis and Enterococcus faecium with an MIC90 of 0...

Hematogenous recurrence is a challenging clinical finding that often leads to fatalities of patients with gastric cancer. Therefore, the identification of specific biomarkers and potential therapeutic target molecules for hematogenous recurrence is required to improve the outcomes of these patients. Here, transcriptome and bioinformatics analyses were conducted to uncover candidate molecules differentially expressed in patients with hematogenous recurrence of gastric cancer. One potential candidate identified was asialoglycoprotein receptor 2 (ASGR2) and small interfering RNA (siRNA) experiments were conducted to determine the effect of manipulating ASGR2 expression has on cell phenotypes...

Peritoneal adhesions remain a major public health problem despite the development of laparoscopy. The rules of microsurgery must be known and followed during any pelvic surgery, even in patients who no longer have a desire for pregnancy. Anti-adhesion products are numerous. All have interest, confirmed by anatomical studies showing a smaller extent or a lesser severity of adhesions associated with their use. No studies, however, show clinical benefit in terms of improved pain or postoperative fertility. Pneumoperitoneum parameters, humidification, and lower abdominal pressure should be optimized to limit peritoneal trauma...

BACKGROUND: Left ventricular assist devices (LVAD) provide a lifesaving bridge to cardiac transplant. Utilization of these devices is increasing in the United States. When a patient undergoes cardiac transplant, the left ventricular device is surgically removed and the driveline is extracted or left tunneled in the subcutaneous tissue. Our group encountered a rare and previously unreported complication of this device: intraperitoneal infiltration of a retained driveline after cardiac transplant causing a small bowel obstruction...

A 52-year-old man died soon after admission to hospital with a severe metabolic acidosis and likely sepsis. He had a past history of alcohol abuse with withdrawal seizures. An abdominal computed tomography scan showed thickened bowel loops but no obvious ischaemic changes, and a blood culture yielded a pure growth of Escherichia coli. At autopsy, the liver showed well-established micro-nodular cirrhosis with steatosis. The peritoneal cavity contained 200 mL of turbid yellow-brown fluid, and the caecum and ascending colon were unusually thickened...
