The innate immune system has been implicated in both AKI and CKD. Damaged mitochondria release danger molecules, such as reactive oxygen species, DNA, and cardiolipin, which can cause NLRP3 inflammasome activation and upregulation of IL-18 and IL-1β It is not known if mitochondrial damage persists long after ischemia to sustain chronic inflammasome activation. We conducted a 9-month study in Sprague-Dawley rats after 45 minutes of bilateral renal ischemia. We detected glomerular and peritubular capillary rarefaction, macrophage infiltration, and fibrosis at 1 month...

Peritonitis is the major complication of peritoneal dialysis (PD). The aim of our present study is to explore the prognostic value of endotoxin level in PD effluent for the prediction of treatment failure in PD-related peritonitis. We studied 325 peritonitis episodes in 223 patients. PD effluent (PDE) was collected every 5 days for endotoxin level and leukocyte count. Patients were followed for relapsing or recurrent peritonitis. We found 20 episodes (6.2%) had primary treatment failure; 41 (12.6%) developed relapsing, 19 (5...

BACKGROUND: The role of microRNA (miRNA) in peritoneal fibrosis and longitudinal change in transport is uncertain. METHODS: We studied 80 new peritoneal dialysis (PD) patients. Peritoneal transport was determined by standard peritoneal equilibration test (PET) of creatinine at baseline. Based on published literature, PD effluent levels of 10 miRNA targets were quantified. PET and miRNA quantification were repeated one year later in 46 patients. RESULTS: Baseline PD effluent levels of all targets tested had modest but significant correlation with peritoneal transport parameters...

Tocilizumab is an interleukin-6 receptor inhibitor licensed for moderate to severe rheumatoid arthritis (RA). We report a case of Tocilizumab monotherapy for severe active RA in a patient with coexisting ulcerative colitis (UC). The patient was intolerant to multiple disease-modifying drugs, so Tocilizumab monotherapy was commenced. We found clinical improvement in both RA and UC. There was no major adverse event after 2 years. Manufacturer advised caution in using Tocilizumab in patient with gastrointestinal ulceration due to an increased risk of bowel perforation...

Orally administered drugs are subject to a number of barriers impacting bioavailability (Foral), causing challenges during drug and formulation development. Physiologically-based pharmacokinetic (PBPK) modelling can help during drug and formulation development by providing quantitative predictions through a systems approach. The performance of three available PBPK software packages (GI-Sim, Simcyp®, and GastroPlus™) were evaluated by comparing simulated and observed pharmacokinetic (PK) parameters. Since the availability of input parameters was heterogeneous and highly variable, caution is required when interpreting the results of this exercise...

BACKGROUND: Neurological events and brain infarction after transcatheter aortic valve replacement (TAVR) are concerns which may be reduced with transcatheter embolic protection (TEP). OBJECTIVE: Evaluate the safety and efficacy of TEP during TAVR. METHODS: Nineteen centers randomized 363 patients undergoing TAVR to safety (n=123), device imaging (n=121), and control imaging (n=119). The primary safety endpoint was major adverse cardiac and cerebrovascular events (MACCE) at 30 days and the primary efficacy endpoint was reduction in new lesion volume in protected brain territories on MRI scans at 2-7 days...

Research on the implications of anxiety in Parkinson's disease (PD) has been neglected despite its prevalence in nearly 50% of patients and its negative impact on quality of life. Previous reports have noted that neuropsychiatric symptoms impair cognitive performance in PD patients; however, to date, no study has directly compared PD patients with and without anxiety to examine the impact of anxiety on cognitive impairments in PD. This study compared cognitive performance across 50 PD participants with and without anxiety (17 PDA+; 33 PDA-), who underwent neurological and neuropsychological assessment...

Viruses represent the most abundant life forms on the planet. Recent experimental and computational improvements have led to a dramatic increase in the number of viral genome sequences identified primarily from metagenomic samples. As a result of the expanding catalog of metagenomic viral sequences, there exists a need for a comprehensive computational platform integrating all these sequences with associated metadata and analytical tools. Here we present IMG/VR (https://img.jgi.doe.gov/vr/), the largest publicly available database of 3908 isolate reference DNA viruses with 264 413 computationally identified viral contigs from >6000 ecologically diverse metagenomic samples...

Checkpoint blockade with antibodies specific for cytotoxic T lymphocyte-associated protein (CTLA)-4 or programmed cell death 1 (PDCD1; also known as PD-1) elicits durable tumor regression in metastatic cancer, but these dramatic responses are confined to a minority of patients. This suboptimal outcome is probably due in part to the complex network of immunosuppressive pathways present in advanced tumors, which are unlikely to be overcome by intervention at a single signaling checkpoint. Here we describe a combination immunotherapy that recruits a variety of innate and adaptive immune cells to eliminate large tumor burdens in syngeneic tumor models and a genetically engineered mouse model of melanoma; to our knowledge tumors of this size have not previously been curable by treatments relying on endogenous immunity...

BACKGROUND/AIMS: Previous studies showed that frailty is prevalent in both pre-dialysis and dialysis patients. However, the prevalence and prognostic implication of frailty in Chinese peritoneal dialysis (PD) patients remain unknown. METHODS: We used a validated questionnaire to determine the Frailty Score of 193 unselected prevalent PD patients. All patients were then followed for 2 years for their need of hospitalization and mortality. RESULTS: Amongst the 193 patients, 134 (69...

The lack of scalable-methods for the growth of 2D MoS2 crystals, an identified emerging material with applications ranging from electronics to energy storage, is a current bottleneck against its large-scale deployment. We report here a two-step ALD route with new organometallic precursors, Mo(NMe2)4 and 1,2-ethanedithiol (HS(CH2)2SH) which consists in the layer-by-layer deposition of an amorphous surface Mo(iv) thiolate at 50 °C, followed by a subsequent annealing at higher temperature leading to ultra-thin MoS2 nanocrystals (∼20 nm-large) in the 1-2 monolayer range...

When clinicians consider extracorporeal life support (ECLS) for acute respiratory distress syndrome (ARDS) patients with hemodynamic instability, both veno-arterial (VA) and veno-venous (VV) ECLS are therapeutic possibilities. We analyzed 17 patients with ARDS on inotropic or vasopressor support requiring ECLS for refractory hypoxemia. After implementing VV ECLS, pressor requirements (based on norepinephrine equivalents) were significantly lower in all patients (P = .0001 for overall comparison across time points)...

Lipid accumulation in renal cells has been implicated in the pathogenesis of obesity-related kidney disease, but the underlying mechanism is poorly understood. Szeto et al. now unravel a central role of mitochondrial dysfunction in a high fat diet-induced glomerulopathy and proximal tubular injury. Moreover, they demonstrate the renoprotective effect of SS31, a mitochondria-targeted antioxidant, in related models. Targeting mitochondria may offer a novel strategy for the therapy of obesity-related kidney disease...
