Vincristine is one of the most common anticancer drugs clinically employed in the treatment of various malignancies. A major side effect associated with vincristine is the development of neuropathic pain, which is not readily relieved by available analgesics. Although efforts have been made to identify the pathogenesis of vincristine-induced neuropathic pain, the mechanisms underlying its pathogenesis have not been fully elucidated. In the present study, a neuropathic pain model was established in Sprague-Dawley rats by intraperitoneal injection of vincristine sulfate...

AIM: Erythropoiesis-stimulating agents (ESAs) are particularly used to treat dialysis patients suffering from anemia due to renal failure. Since March 2014, ESAs have no longer been funded on top-of-diagnosis-related groups (DRGs) in French hospitals and are funded via DRGs. There are two ways to fund dialysis in French hospitals: the 'DRG for dialysis in session' and the 'off-dialysis DRG', which is not a DRG and consists in a supplement tariff specific to dialysis for patients hospitalized for another main reason than dialysis...

Ectopic impulse discharge (ectopia) generated in the soma of afferent neurons in dorsal root ganglia (DRGs) following nerve injury is thought to be a major contributor to neuropathic pain. The DRG is thus a prime interventional target. The process of electrogenesis (impulse generation) in the DRG is far more sensitive to systemically administered Na channel blockers than the process of impulse propagation along sensory axons. It should therefore be possible to selectively suppress DRG ectopia with local application of membrane stabilizing agents without blocking normal impulse traffic...

Satellite glial cells (SGCs) are glial cells in the peripheral nervous system that form sheaths around the neuronal cell body. This unique arrangement of SGCs allows it to exert a highly regulated control over the neuronal microenvironment. Not much is known about the origin of SGCs. In this study, we examine the development of SGCs. We show that rat SGCs develop postnatally and these cells express a number of markers associated with Schwann cell precursors, in particular cadherin-19 (CDH19) even in adult DRGs...

Mouse artificial chromosome (MAC) vectors have several advantages as gene delivery vectors, such as stable and independent maintenance in host cells without integration, transferability from donor cells to recipient cells via microcell-mediated chromosome transfer (MMCT), and the potential for loading a megabase-sized DNA fragment. Previously, a MAC containing a multi-integrase platform (MI-MAC) was developed to facilitate the transfer of multiple genes into desired cells. Although the MI system can theoretically hold five gene-loading vectors (GLVs), there are a limited number of drugs available for the selection of multiple-GLV integration...

BACKGROUND AND PURPOSE: The P2X3 receptor (P2X3R) is a major receptor in the processing of nociceptive information in dorsal root ganglia (DRGs). We investigated the role of the P2X3R and the detailed mechanisms underlying chronic morphine-induced analgesic tolerance in rats. EXPERIMENTAL APPROACHES: Under isoflurane inhalation anaesthesia, intrathecal catheters were implanted in male Sprague-Dawley rats. Repeated intrathecal (i.t.) morphine treatment was used to induce anti-nociceptive tolerance...

BACKGROUND: Hospital revenues generated by diagnosis-related groups (DRGs) are in part dependent on the coding of secondary diagnoses. Therefore, more and more hospitals trust specialized coders with this task, thereby relieving doctors from time-consuming administrative burdens and establishing a highly professionalized coding environment. However, it is vastly unknown if the revenues generated by the coders do indeed exceed their incurred costs. METHODS: Coding data from the departments of dermatology, ophthalmology, and infectious diseases from Rostock University Hospital from 2007-2016 were analyzed for the effects of secondary diagnoses on the resulting DRG, i...

Colorectal cancer (CRC) heritability has been estimated to be around 30%. However, mutations in the known CRC-susceptibility genes explain CRC risk in fewer than 10% of affected individuals. Germline mutations in DNA-repair genes (DRGs) have recently been reported in CRC, but their contribution to CRC risk is largely unknown. We evaluated the gene-level germline mutation enrichment of 40 DRGs in 680 unselected CRC individuals and 27,728 ancestry-matched cancer-free adults. Significant findings were then examined in independent cohorts of 1,661 unselected CRC individuals and 1,456 individuals with early-onset CRC...

Both calpain-2 (CALP2) and tumor necrosis factor-α (TNF-α) contribute to persistent bilateral hypersensitivity in animals subjected to L5 ventral root transection (L5-VRT), a model of selective motor fiber injury without sensory nerve damage. However, specific upstream mechanisms regulating TNF-α overexpression and possible relationships linking CALP2 and TNF-α have not yet been investigated in this model. We examined changes in CALP2 and TNF-α protein levels and alterations in bilateral mechanical threshold within 24 h following L5-VRT model injury...

The acutely dissociated neurons from the dorsal root ganglia (DRGs) are extensively used. The effects of acute dissociation on the properties of these neurons are, however, not clear. In this study, the action potentials (APs) were recorded from both acutely dissociated and in vivo identified DRG neurons with patch clamp and sharp electrode recording techniques, respectively. We found that acute dissociation slowed both the depolarizing and repolarizing rate of APs, and elongated the AP duration (APD). The lower recording temperature presented in the acutely dissociated neurons contributed to about 10% of these differences...

Plasticity in dorsal root ganglion (DRG) neurons that promotes pain requires activity-dependent mRNA translation. Protein synthesis inhibitors block the ability of many pain-promoting molecules to enhance excitability in DRG neurons and attenuate behavioral signs of pain plasticity. In line with this, we have recently shown that phosphorylation of the 5' cap-binding protein, eIF4E, plays a pivotal role in plasticity of DRG nociceptors in models of hyperalgesic priming. However, mRNA targets of eIF4E phosphorylation have not been elucidated in the DRG...

BACKGROUND: The U.S. Centers for Medicare & Medicaid Services (CMS) has been considering the implementation of a mandatory bundled payment program, the Surgical Hip and Femur Fracture Treatment (SHFFT) model. However, bundled payments without appropriate risk adjustment may be inequitable to providers and may restrict access to care for certain patients. The SHFFT proposal includes adjustment using the Diagnosis-Related Group (DRG) and geographic location. The goal of the current study was to identify and quantify patient factors that could improve risk adjustment for SHFFT bundled payments...

PURPOSE: To elucidate the effects of growth differentiation factor-6 (GDF6) on: (i) gene expression of inflammatory/pain-related molecules and structural integrity in the rabbit intervertebral disc (IVD) degeneration model, and (ii) sensory dysfunction and changes in pain-marker expression in dorsal nerve ganglia (DRGs) in the rat xenograft radiculopathy model. METHODS: Forty-six adolescent rabbits received anular-puncture in two non-consecutive lumbar IVDs. Four weeks later, phosphate-buffered saline (PBS) or GDF6 (1, 10 or 100 µg) was injected into the nucleus pulposus (NP) of punctured discs and followed for 4 weeks for gene expression analysis and 12 weeks for structural analyses...

BACKGROUND: T helper type 2 cell-released interleukin 31 (IL-31) is a critical mediator in atopic dermatitis (AD), a prevalent and debilitating chronic skin disorder. Brain-derived natriuretic peptide (BNP) has been described as a central itch mediator. The importance of BNP in peripheral (skin-derived) itch and its functional link to IL-31 within the neuro-immune axis of the skin is unknown. OBJECTIVE: To investigate the function of BNP in the peripheral sensory system and skin in IL-31-induced itch and neuro-epidermal communication in AD...
