Asymptomatic microscopic hematuria is an important clinical sign of urinary tract malignancy. Asymptomatic microscopic hematuria has been variably defined over the years. In addition, the evidence primarily is based on data from male patients. However, whether the patient is a man or a woman influences the differential diagnosis of asymptomatic microscopic hematuria, and the risk of urinary tract malignancy (bladder, ureter, and kidney) is significantly less in women than in men. Among women, being older than 60 years, having a history of smoking, and having gross hematuria are the strongest predictors of urologic cancer...

PURPOSE: To evaluate if the widespread adoption of a minimally invasive approach to radical nephrectomy has affected short- and long-term patient outcomes in the modern era. METHODS: A retrospective cohort study of patients who underwent radical nephrectomy from 2001 to 2012 was conducted using the US National Cancer Institute Surveillance Epidemiology and End Results (SEER) Program and Medicare insurance program database. Patients who underwent open surgery were compared to those who underwent minimally invasive surgery using propensity score matching...

BACKGROUND: Primary human B cells chronic lymphocytic leukemia undergoes apoptosis, from which they can be rescued by contact with stromal cells or by the addition of specific soluble factor, when cultured in vitro. For research purposes of the behavior of CLL cells we created 3D in vitro model in which we simulated appropriate microenvironment for CLL cells to allow study the mechanism of survival of these cells in long-term cultivation. MATERIAL AND METHODS: Our aim was the scaffold structure to be geometrically similar to the 3D morphology of supporting bone marrow tissue in a trabecular bone; the 3D scaffold was also designed to conform to biocompatibility, sufficiently large surface area for cell attachment, high porosity for cell migration, proliferation and transport of nutrients...

BACKGROUND: Aspiration can occur in patients of any age group, but it can be prevented. The primary population at risk is made up of survivors of cancer because of their increased risk of mucositis, mucosal atrophy, and dysphagia associated with chemotherapy, radiotherapy, and the disease process itself. The rate of incidence of aspiration cannot be quantified, because minor cases of aspiration often go unreported. Sequelae ensuing from aspirations can include pneumonia, end-stage kidney disease, dialysis, and death...

Proteomic and genomic techniques have reached full maturity and are providing unforeseen details for the comprehensive understanding of disease pathologies at a fraction of previous costs. However, for kidney diseases, many gaps in such information remain to inhibit major advances in the prevention, treatment and diagnostics of these devastating diseases, which have enormous global impact. The discovery of ubiquitous extracellular vesicles (EV) in all bodily fluids is rapidly increasing the fundamental knowledge of disease mechanisms and the ways in which cells communicate with distant locations in processes of cancer spread, immunological regulation, barrier functions and general modulation of cellular activity...

Adenosine triphosphate (ATP)-binding cassette (ABC) transporters are highly expressed in tumor cells, as well as in organs involved in absorption and secretion processes, mediating the ATP-dependent efflux of compounds, both endogenous substances and xenobiotics, including drugs. Their expression and activity levels are modulated by the presence of inhibitors, inducers and/or activators. In vitro, ex vivo and in vivo studies with both known and newly synthesized P-glycoprotein (P-gp) inducers and/or activators have shown the usefulness of these transport mechanisms in reducing the systemic exposure and specific tissue access of potentially harmful compounds...

Ten years after Fire and Melo's Nobel Prize for discovery of gene silencing by double-stranded RNA, a remarkable progress was achieved in RNA interference (RNAi). Changes in the chemical structure of synthetic oligonucleotides make them more stable and specific, and new delivery strategies became progressively available. The attention of pharmaceutical industry rapidly turned to RNAi, as an opportunity to explore new drug targets. This review addresses nine small-interfering RNAs (siRNAs) and one unique microRNA (miRNA) inhibitor, which entered the phase 2-3 clinical trials...

Kidney transplantation is the best treatment for end-stage renal failure. It prolongs the patient's life, improves quality of life and reduces costs associated with renal replacement therapy. Increasingly, newer immunosuppressive regimens allow for the proper functioning of the transplanted organ for many years. The progress in transplantation, qualification patients in older age for the procedure and longer survival of kidney graft lead to an increase in the number of patients receiving immunosuppressive drugs...

Introduction: Hospitalization of patients with cancer has a significant economic impact and avoidance where unnecessary has great potential for significant cost savings for patients, individual hospitals and the health system in general. Methods: Demographic, clinical and economical data were collected from medical records in our hospital retrospectively. Oncology clinicians reviewed medical records to categorize each hospitalization as “potentially avoidable” or “not avoidable.” Patient demographic and clinical data were abstracted and quantitative and qualitative analyses were performed to identify patient characteristics and outcomes associated with potentially avoidable hospitalizations...

Importance: The comorbid conditions of patients with cancer affect treatment decisions, which in turn affect survival and health-related quality-of-life outcomes. Comparative effectiveness research studies must account for these conditions via medical record abstraction or patient report. Objective: To examine the agreement between medical records and patient reports in assessing comorbidities. Design, Setting, and Participants: Patient-reported information and medical records were prospectively collected as part of the North Carolina Prostate Cancer Comparative Effectiveness & Survivorship Study, a population-based cohort of 881 patients with newly diagnosed localized prostate cancer enrolled in the North Carolina Central Cancer Registry from January 1, 2011, through June 30, 2013...

Cadmium (Cd) is an environmental toxicant of widespread exposure and pervasive toxicity. Absorption, systemic transport and uptake of Cd are mediated by metal transporters that the body uses for acquisition of physiologically-essential elements, notably of iron, zinc and calcium. Currently, human exposure to Cd is known to damage the kidneys, especially the proximal tubular cells that actively reabsorb Cd along with zinc, glucose and amino acids in the glomerular filtrate. Severe kidney damage, glycosuria and proteinuria are known outcomes after high dietary Cd intake (> 200 µg/day)...

BACKGROUND: Despite the urgent need for evidence to guide the end-of-life (EOL) care for patients with chronic kidney disease (CKD), we have limited knowledge of the costs and intensity of EOL care in this population. The present study examined patterns and predictors for EOL care intensity among elderly patients with CKD. METHODS: We conducted a retrospective nationwide cohort study utilizing the Taiwan National Health Insurance (NHI) Research Database. A total of 65,124 CKD patients aged ≥ 60 years, who died in hospitals or shortly after discharge between 2002 and 2012 were analyzed...

BACKGROUND: Previous studies have documented the high costs of non-dialysis dependent chronic kidney disease (CKD) but out-of-pocket healthcare expenditures remain poorly explored. This study described total direct and out-of-pocket expenditures for adults with non-dialysis dependent CKD and compared expenditures with those for cancer or stroke. METHODS: This study used data from the 2011-2013 Medical Expenditure Panel Survey, a national survey of healthcare expenditures in the U...

BACKGROUND: Next-generation sequencing of matched tumor and normal biopsy pairs has become a technology of paramount importance for precision cancer treatment. Sequencing costs have dropped tremendously, allowing the sequencing of the whole exome of tumors for just a fraction of the total treatment costs. However, clinicians and scientists cannot take full advantage of the generated data because the accuracy of analysis pipelines is limited. This particularly concerns the reliable identification of subclonal mutations in a cancer tissue sample with very low frequencies, which may be clinically relevant...

Despite many achievements in renal transplant in the past few years regarding immunosuppression and tissue matching, the rates of early and late graft loss and return to dialysis are still high. Many of those with primary graft failure will be listed for a kidney retransplant, as this allows for better quality of life than dialysis. Many challenges face those requiring renal retransplant, including first graft nephrectomy and whether site of retransplant should be ipsilateral or contralateral, whether to conduct preemptive retransplant or wait while on dialysis, additional immunologic factors, immunosuppression after retransplant, cancer risk, BK virus infection, and retransplant in pediatrics...
