Leiomyosarcoma (LMS) is a rare but well-recognized malignant soft tissue sarcoma of smooth muscle origin. Metastases commonly occur in the lungs, liver, kidney, brain, and bone. Cases of metastatic osseous lesions or other extradural space-occupying masses secondary to LMS leading to neurologic compromise are relatively commonplace in the literature. Conversely, cases of intramedullary spinal cord metastasis (ISCM), an unusual entity as a sequela of any cancer, are exceedingly rare as a consequence of LMS. Only 2 cases of an ISCM from LMS are currently documented in the literature, and to the best of our knowledge, no case is described in the rehabilitation literature...

A long time ago, the links between renal disease and malignancy were observed, however, quite recently, their importance was recognized and 'new' subspecialty in nephrology, namely 'onconephrology' was established. In the XXI century, patients with malignancy make up the most growing number of the subjects seen for nephrology consult and/or critical care nephrology services. A plethora of renal problems may be found in patients with malignancy. They may influence not only their short-term outcomes but also the adequate therapy of the underlying oncological problem...

Hypertension-related, calcium-regulated gene (HCaRG/COMMD5) is highly expressed in renal proximal tubules, where it contributes to the control of cell proliferation and differentiation. HCaRG accelerates tubular repair by facilitating re-differentiation of injured proximal tubular epithelial cells, thus improving mouse survival after acute kidney injury. Sustained hyper-proliferation and de-differentiation are important hallmarks of tumor progression. Here, we demonstrate that cancer cells overexpressing HCaRG maintain a more differentiated phenotype, while several of them undergo autophagic cell death...

Cisplatin is a chemotherapeutic agent widely used in the treatment of various cancers. However, cisplatin can induce nephrotoxicity and neurotoxicity, limiting its dosage and usage. Galangin, a natural flavonol, has been found to exhibit anti-oxidant and anti-inflammatory effects in vivo. Here, we investigated the effects of galangin on cisplatin-induced acute kidney injury (AKI) and its molecular mechanisms in mice. Galangin administration reduced the cisplatin-induced oxidative stress by decreasing renal MDA and 3-NT formations...

Continuous renal replacement therapy (CRRT) is one of the dialysis modalities for critically ill patients. Despite intensive dialysis care, a high mortality rate is found in these patients. Our objective was to investigate the factors associated with poor outcomes in these patients. We conducted a retrospective cohort study using the National Health Insurance Research Database. Records of critically ill patients who received CRRT between 2007 and 2011 were retrieved, and the patients were categorized into two groups: those with acute kidney injury (AKI) and those with history of end-stage renal disease (ESRD)...

BACKGROUND: Cytoreductive surgery and hyperthermic intra-peritoneal chemotherapy (CRS-HIPEC) prolongs survival in patients with metastatic peritoneal disease. We look at the incidence of acute kidney injury (AKI) in patients who have received cisplatin during CRS-HIPEC in the treatment of peritoneal carcinomatosis from an ovarian primary, and identify possible peri-operative risk factors. METHODS: Between 2005 and 2013, we performed CRS-HIPEC on 47 patients with ovarian primaries and peritoneal metastasis...

BACKGROUND: Pemetrexed (PEM) is a new-generation multitargeted antifolate agent with a demonstrated broad-spectrum activity in several types of human cancers, including non-small cell lung cancer (NSCLC) and mesothelioma. Major side effects include dose-limiting hematologic toxicities. PEM nephrotoxicity is well known; however, its frequency is considered to be low. CASE PRESENTATION: Here we report two cases of acute kidney injury (AKI) related to PEM administration (500 mg/m2) in patients with NSCLC...

Acute kidney injury (AKI), resulting from chemotherapeutic agents such as cisplatin, remains an obstacle in the treatment of cancer. Cisplatin-induced AKI involves apoptotic and necrotic cell death, pathways regulated by sphingolipids such as ceramide and glucosylceramide. Results from this study indicate that C57BL/6J mice treated with cisplatin had increased ceramide and hexosylceramide levels in the renal cortex 72 h following cisplatin treatment. Pre-treatment of mice with inhibitors of acid sphingomyelinase and de novo ceramide synthesis (amitriptyline and myriocin, respectively) prevented accumulation of ceramides and hexosylceramide in the renal cortex and protected from cisplatin-induced AKI...

Adoption of Electronic Health Record (EHR) systems has led to collection of massive healthcare data, which creates oppor- tunities and challenges to study them. Computational phenotyping offers a promising way to convert the sparse and complex data into meaningful concepts that are interpretable to healthcare givers to make use of them. We propose a novel su- pervised nonnegative tensor factorization methodology that derives discriminative and distinct phenotypes. We represented co-occurrence of diagnoses and prescriptions in EHRs as a third-order tensor, and decomposed it using the CP algorithm...

Approximately 30% of all cancer patients treated with cisplatin, a widely used, broad-spectrum chemotherapeutic agent, experience acute kidney injury (AKI). Almost all patients receiving cisplatin have magnesium (Mg) losses, which are proposed to aggravate AKI. Currently, there are no methods to successfully treat or prevent cisplatin-AKI. While Mg supplementation has been shown to reduce AKI in experimental models and several small clinical trials, the effects of Mg status on tumor outcomes in immunocompetent tumor-bearing mice and humans have not been investigated...

Cisplatin chemotherapy often causes acute kidney injury (AKI) in cancer patients. There is increasing evidence that mitochondrial dysfunction plays an important role in cisplatin-induced nephrotoxicity. Degradation of damaged mitochondria is carried out by mitophagy. Although mitophagy is considered of particular importance in protecting against AKI, little is known of the precise role of mitophagy and its molecular mechanisms during cisplatin-induced nephrotoxicity. Also, evidence that activation of mitophagy improved mitochondrial function is lacking...

Renal function after renal cancer surgery is a critical component of survivorship. Quantity and quality of preserved parenchyma are the most important determinants of functional recovery; type and duration of ischemia play secondary roles. Several studies evaluated surgical techniques to minimize ischemia; however, long-term outcomes and potential benefits over clamped partial nephrectomy (PN) have not been consistently demonstrated. Analysis of acute kidney injury (AKI) after PN suggest that most kidneys recover strongly even if AKI is experienced after surgery...

Despite the high prevalence of acute kidney injury (AKI) and its association with increased morbidity and mortality, therapeutic approaches for AKI are disappointing. This is largely attributed to poor understanding of the pathogenesis of AKI. Heparanase, an endoglycosidase that cleaves heparan sulfate, is involved in extracellular matrix turnover, inflammation, kidney dysfunction, diabetes, fibrosis, angiogenesis and cancer progression. The current study examined the involvement of heparanase in the pathogenesis of ischemic reperfusion (I/R) AKI in a mouse model and the protective effect of PG545, a potent heparanase inhibitor...
