EDITORIAL
John T Daugirdas, Daniel Schneditz
The association between higher ultrafiltration rates and poor outcomes in hemodialysis patients has received increased attention, to the point that various regulatory entities are considering adding ultrafiltration rate as a quality measure to be monitored and controlled. Most of the discussion to date has focused on ultrafiltration rate scaled to body weight, or more correctly, body mass (ml/hour per kg). One outcome study suggests that ultrafiltration rate might best be not scaled at all to body size, as modestly higher ultrafiltration rate in very small-size patients may be associated with some survival benefit, probably via increased dietary intake...

OBJECTIVE: The FRUIT-RCT concluded that low-molecular-weight heparin added to aspirin compared to treatment with aspirin alone is beneficial in the prevention of early-onset hypertensive disorders of pregnancy (HD) in women with inheritable thrombophilia and prior HD and/or a small-for-gestational age (SGA) infant leading to delivery before 34 weeks gestation. The aim of this study is to answer the question whether aspirin resistance is associated with recurrent HD. STUDY DESIGN: Women with and without recurrent HD matched for age, study arm, and chronic hypertension were invited for this follow-up study 6-16 years after they participated in the FRUIT-RCT...

Left ventricular hypertrophy is a strong causal risk factor of cardiovascular morbidity and death in end stage kidney failure, and its prognostic value is taken for granted in this population. However, the issue has never been formally tested by state-of-art prognostic analyses. Therefore, we determined the prognostic power of the left ventricular mass index (LVMI) for all-cause and cardiovascular death beyond and above that provided by well validated clinical risk scores, the annualized rate of occurrence cohort risk scores (ARO, all cause death risk and cardiovascular risk)...

In this study, poly (1,8- octanediol citrate) (POC) was used to modify polyethersufone (PES) based membrane to enhance its hemocompatibility. Different compositions of POC (0-3%) were added into the polyethersulfone (PES) dope solutions and polyvinylpyrrolidone (PVP) was used as pore forming agent. The hemocompatible POC modified PES membranes were fabricated through phase-inversion technique. The prepared membranes were characterized using attenuated total reflectance-fourier transform infrared (ATR-FTIR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), Atomic-force microscopy (AFM), contact angle, Zeta-potential, membrane porosity and pore size and pure water flux (PWF) and BSA rejection...

During the development of an individual from a single cell to prenatal stages to adolescence to adulthood and through the complete life span, humans are exposed to countless environmental and stochastic factors, including estrogenic endocrine disrupting chemicals. Brain cells and neural circuits are likely to be influenced by estrogenic endocrine disruptors (EEDs) because they strongly dependent on estrogens. In this review, we discuss both environmental, epidemiological, and experimental evidence on brain health with exposure to oral contraceptives, hormonal therapy, and EEDs such as bisphenol-A (BPA), polychlorinated biphenyls (PCBs), phthalates, and metalloestrogens, such as, arsenic, cadmium, and manganese...

A 67-year-old male patient developed multiple myeloma with acute renal failure caused by myeloma kidney. Although a very good partial response was achieved with bortezomib with dexamethasone (BD) therapy under temporary dialysis, relapse occurred 3 years later. Thalidomide was added to the BD therapy but was discontinued because of drug-induced eczema. Subsequently, bone lesions and chromosomal abnormalities appeared. Because renal failure progressed with increased serum free light chain levels, maintenance hemodialysis was introduced...

BACKGROUND: Hepatitis C virus (HCV) still has significant prevalence in kidney transplant (KT) recipients and is related to poor recipient and graft survival. New direct-acting antivirals (DAA) are leading to a radical change in the problem. METHODS: We studied HCV prevalence at the time of transplantation and in follow-up patients, the way cases are handled, and the results of DAA. RESULTS: A total of 2,001 KT had been performed in our center since 1978...

Leaves are present in all land plants and are specialized organs for light harvesting. They arise at the flanks of the shoot apical meristem (SAM), and develop into lamina structures that exhibit adaxial/abaxial (upper/lower side of the leaf) polarity. At the molecular level, an intricate regulatory network determines ad-/abaxial polarity in Arabidopsis thaliana leaves, where the Class III Homeodomain Leucine Zipper (HD-ZIPIII) and KANADI (KAN) proteins are key mediators. The HD-ZIPIII REVOLUTA (REV) is expressed in the adaxial domain of lateral organs, whereas KAN1 is involved in abaxial differentiation...

Hoarding disorder (HD) was originally conceptualized as a subcategory of obsessive compulsive disorder (OCD), and numerous studies have in fact focused exclusively on investigating the comorbidity between OCD and HD. Hoarding behavior can nevertheless also be found in other clinical populations and in particular in patients with eating disorders (ED), anxiety disorders (AD), major depression (MD), and psychotic disorders (PD). The current study was carried out with the aim of investigating, using a validated instrument such as the Saving Inventory-Revised (SI-R), the presence of HD symptoms in patients diagnosed with ED, AD, MD, and PD...

Neurodegenerative diseases are a heterogeneous group of disorders that are incurable and characterized by the progressive degeneration of the function and structure of the central nervous system (CNS) for reasons that are not yet understood. Neurodegeneration is the umbrella term for the progressive death of nerve cells and loss of brain tissue. Because of their high energy requirements, neurons are especially vulnerable to injury and death from dysfunctional mitochondria. Widespread damage to mitochondria causes cells to die because they can no longer produce enough energy...

Glutamate is the most important excitatory neurotransmitter of the mammalian central nervous system (CNS), playing an important role in memory, synaptic plasticity and neuronal development. However, glutamate overstimulation is also implicated in neuronal cell death. There are two major types of glutamate receptors: ionotropic and metabotropic. Thus far, eight metabotropic glutamate receptors (mGluRs) subtypes have been characterized and are divided into three subgroups based on sequence homology and cell signaling activation...

Neurons need a continuous supply of glucose, the major source of energy for mammalian brain metabolism. The central nervous system is protected by three main physiological cell barriers. Cell membranes are impermeable for glucose, therefore glucose is transferred across the cell membranes by specific transport proteins: sodium-independent glucose transporters (GLUTs), encoded by SLC2 genes, and sodium-dependent glucose transporters (for example SGLTs), encoded by SLC5 genes. Human brain expresses 10 GLUT proteins and 10 proteins encoded by SLC5 genes...

AIM: In hemodialysis patients, the need to have intercurrent sodium and water intake removed by ultrafiltration increases disease burden through the symptoms and signs that occur during hemodialysis (HD). This added burden may be mitigated by reduction of dietary sodium intake. The National Kidney Foundation (NKF) recommends 2400 mg of dietary sodium daily for patients on HD, and the American Heart Association (AHA) suggests 1500 mg, evidence is lacking, however, to support these recommendations in HD...

AIMS: Appropriate glycemic control without hypoglycemia is important in patients with type 2 diabetes on hemodialysis. Teneligliptin, a novel dipeptidyl peptidase-4 inhibitor, can be used without dose adjustment for these patients. Using continuous glucose monitoring (CGM), we evaluated the efficacy and safety of adding teneligliptin to insulin therapy. METHODS: Twenty-one type 2 diabetes mellitus patients on hemodialysis treated with insulin were enrolled. After the adjustment of insulin dose, their blood glucose level was monitored by CGM...

Alexandre Vallée, Yves Lecarpentier
The molecular mechanisms underlying the pathophysiology of Alzheimer's disease (AD) are still not fully understood. In AD, Wnt/beta-catenin signaling has been shown to be downregulated while the peroxisome proliferator-activated receptor (PPAR) gamma (mARN and protein) is upregulated. Certain neurodegenerative diseases share the same Wnt/beta-catenin/PPAR gamma profile, such as bipolar disorder and schizophrenia. Conversely, other NDs share an opposite profile, such as amyotrophic lateral sclerosis, Parkinson's disease, Huntington's disease, multiple sclerosis, and Friedreich's ataxia...

Regeneration of injured nerves is likely occurring in the peripheral nervous system, but not in the central nervous system. Although protein-coding gene expression has been assessed during nerve regeneration, little is currently known about the role of non-coding RNAs (ncRNAs). This leaves open questions about the potential effects of ncRNAs at transcriptome level. Due to the limited availability of human neuropathic pain (NP) data, we have identified the most comprehensive time-course gene expression profile referred to sciatic nerve (SN) injury and studied in a rat model using two neuronal tissues, namely dorsal root ganglion (DRG) and SN...

Cells have developed an evolutionary obligation to survey and maintain proteome fidelity and avoid the possible toxic consequences of protein misfolding and aggregation. Disturbances to protein homoeostasis (proteostasis) can result in severe cellular phenotypes and are closely linked with the accumulation of microscopically visible deposits of aggregated proteins. These include inclusion bodies found in AD (Alzheimer's disease), HD (Huntington's disease) and ALS (amyotrophic lateral sclerosis) patient neurons...
