AIMS AND OBJECTIVES: The aim of this study was to evaluate the clinical validity of indicators of the nursing diagnosis of "ineffective protection" in hemodialysis patients. BACKGROUND: Hemodialysis patients have reduced protection. Studies on the nursing diagnosis of "ineffective protection" are scarce in the literature. The use of indicators to diagnose "ineffective protection" could improve the care of hemodialysis patients. The clinical usefulness of the indicators requires clinical validation...

INTRODUCTION: Uric acid (UA), a breakdown product of purines, has been associated with mortality in different populations. Less is known about associations between hyperuricemia and mortality in chronic kidney disease (CKD) patients, later undergoing hemodialysis (HD), during a long observation period. The aim of this study was to determine the impact of elevated UA levels on long-term (19.5 years) survival of CKD patients. METHODS: 120 CKD patients (49 female, 71 male) enrolled in our study were observed from their first visit at the patients' nephrology outpatient clinic (NOC)...

BACKGROUND: The optimal timing of vascular access referral for patients with chronic kidney disease who may need hemodialysis (HD) is a pressing question in nephrology. Current referral policies have not been rigorously compared with respect to costs and benefits and do not consider patient-specific factors such as age. STUDY DESIGN: Monte Carlo simulation model. SETTING & POPULATION: Patients with chronic kidney disease, referred to a multidisciplinary kidney clinic in a universal health care system...

In 1977 Peter Kramer performed the first CAVH (continuous arteriovenous hemofiltration) treatment in Gottingen, Germany. CAVH soon became a reliable alternative to hemo- or peritoneal dialysis in critically ill patients. The limitations of CAVH spurred new research and the discovery of new treatments such as CVVH and CVVHD (continuous veno-venous hemofiltration and continuous veno-venous hemodialysis). The alliance with industry led to development of new specialized equipment with improved accuracy and performance in delivering continuous renal replacement therapies (CRRTs)...

♦Background: Improvement in the rates of home dialysis has been a desirable but difficult-to-achieve target for United States nephrology. Provision of comprehensive predialysis education (CPE) in institutes with established home dialysis programs has been shown to facilitate a higher home dialysis choice amongst chronic kidney disease (CKD) patients. Unfortunately, limited data have shown the efficacy of such programs in the United States or in institutes with small home dialysis (HoD) programs. ♦ Methods: We report the retrospective findings examining the efficacy of a CPE program in the early period after its establishment, with reference to its impact on the choice and growth of a small HoD program...

Hyperhomocysteinemia has attracted a lot of attention in renal patients, not only because of its close relationship with renal function but also because it has been implicated as an independent cardiovascular risk factor in these patients. An increased level of C-reactive protein (CRP) has been reported to be a strong predictor of cardiovascular mortality in hemodialysis (HD) patients. The aim of this study was to assess the association between homocysteine (Hcy) and highly sensitive CRP (hsCRP) in cardiovascular risk prediction in children with chronic kidney disease (CKD) on HD...

Chronic kidney disease (CKD) exacerbating vascular disease poses a major challenge to nephrology. Surgically placed vascular fistulas, as an aid to hemodialysis prior to kidney transplant, have extended many lives, while post-surgical restenosis closure of the fistula by smooth muscle cells affects many lives. When post-surgical restenosis is developed, palliative measures are almost always surgical: there are no effective drug treatments. In this study, we offer a testable hypothesis that effects of CKD on widely distributed vascular diseases and the phenomenon of fistula restenosis are both driven by the pathologic creation of non-dividing smooth muscle cells via asymmetric division of exponentially increasing metakaryotic stem cells...

Hyperkalemia is not uncommon in patients with end-stage renal disease (ESRD) on maintenance hemodialysis, often related to dietary indiscretion, following the prolonged inter-dialytic weekend interval in patients on thrice weekly hemodialysis treatments, and sometimes the adverse effects of medications such as RAAS blocking agents. Moreover, hyperkalemia following extended cardiac surgery can result from the use of high-potassium containing cardioplegic solutions used during cardiopulmonary bypass. Nevertheless, different from the foregoing, in the nephrology literature, there have been very rare reports of potentially life-threatening hyperkalemia following cardiac valve replacement procedure...

Although responsibility is a fundamental determinant in medical practice, physicians are generally unfamiliar with its principles. The same is true for disclosure requirements and requests for compensation in the event of physical injury. We report on a representative survey of iatrogenic complications that may arise after the implementation of vascular access for haemodialysis and that illustrate's the physician's responsibility and obligation to inform the patient. Vascular access steal syndrome is a serious complication of arteriovenous fistulas, and physicians may not be sufficiently aware of the likelihood of its occurrence...

BACKGROUND: Mortality in the immediate post-hemodialysis transition period is extremely high. Many end-stage renal disease (ESRD) patients in the US start dialysis in an inpatient setting, but the characteristics of patients starting dialysis as inpatients, and the association of inpatient hemodialysis transition with mortality remain unclear. METHODS: We examined 48,261 US veterans who transitioned to hemodialysis between October 2007 and September 2011. Associations of inpatient hemodialysis starting with all-cause mortality were examined in Cox proportional hazard models, with adjustments for demographics, comorbidities, vascular access type, pre-dialysis nephrology care and medication use, and last pre-ESRD estimated glomerular filtration rate and hemoglobin...

BACKGROUND: Simkania negevensis is an obligate intracellular bacterium belonging to the family Simkaniaceae in the Chlamydiales order. It is considered an ubiquitous microorganism and aquatic environments may be involved as a source of infection for humans. It was just isolated in samples from domestic water supplies and from mains water supplies, like spa water or swimming pool water, confirming its ability to resist to the common chlorination treatments. Evidence indicates a possible role of the microorganism in respiratory tract infections, in gastroenteric disorders and in the pathogenesis of cardiovascular disease, furthermore it has hypothesized that it could play a role in lung transplant rejection...

BACKGROUND: No controlled trials in children with end-stage kidney disease have assessed the benefits of more frequently administered hemodialysis (HD). METHODS: We conducted a multicenter, crossover pilot trial to determine if short, more frequent (5 days per week) in-center HD was feasible and associated with improvements in blood pressure compared with three conventional HD treatments per week. Because adult studies have not controlled for the weekly duration of dialysis, we fixed the total treatment time at 12 h a week of dialysis during two 3-month study periods; only frequency varied from 5 to 3 days per week between study periods...

Urea removal has become a key measure of the intensity of dialysis treatment for kidney failure. Small solute removal, exemplified by Kt/Vurea, has been broadly applied as a means to quantify the dose of thrice weekly hemodialysis. Yet, the reliance on small solute clearances alone as a measure of dialysis adequacy fails fully to quantify the intended clinical effects of dialysis therapy. This review aims to (1) understand the strengths and limitations of small solute kinetics as a surrogate marker of dialysis dose, and (2) present the prospect of a more comprehensive construct for dialysis dose, one that considers more broadly the goals of ESRD care to maximize both quality of life and survival...

Tamara K Jemcov, Wim Van Biesen
Many guidelines recommend that end-stage renal disease (ESRD) patients should have a permanent vascular access, preferably an autologous arteriovenous fistula (AVF), at the start of renal replacement therapy. Nevertheless, a large proportion of patients still start hemodialysis with a central venous catheter (CVC). On the other hand, there are increasing numbers of patients in whom an AVF has been created, but who never actually end up on dialysis, as well as a substantial number of patients in whom creation of a vascular access has been attempted unsuccessfully...

Branchio-oto-renal (BOR) syndrome is an autosomal dominant disorder characterized by the coexistence of branchial cysts or fistulae, external ear malformation with pre-auricular pits or tags, hearing impairment and renal malformations. However, the presence of the main features varies in affected families. Here, we present a 16-year-old boy admitted to the Department of Nephrology at the Pediatric Clinic, University Clinical Center of Kosovo, Pristina, Republic of Kosovo because of severe renal insufficiency diagnosed 6 years ago, which progressed to end-stage renal failure...
