A flux dialysis method to measure unbound fraction (fu) of compounds with high protein binding and other challenging properties was tested and validated. The method is based on the principle that the initial flux rate of a compound through a size-excluding dialysis membrane is proportional to the product of compound initial concentration, fu and unbound dialysis membrane permeability (Pmem). Therefore fu can be determined from initial concentration and flux rate, assuming membrane Pmem is known. Compound initial flux rates for 14 compounds were determined by dialyzing human plasma containing compound (donor side) versus compound-free plasma (receiver side) and measuring the rate of compound appearance into the receiver side...

BACKGROUND: Surgical residency training programs in the United States are modeled on the principle of graduated responsibility. Residents are given greater responsibility and autonomy in the operating room and during perioperative care as they gain surgical skills and progress through their training. The impact of this method of surgical training on patient outcomes remains unknown. The purpose of this study is to compare early patient morbidity and mortality after bariatric surgery in cases with and without resident participation using the American College of Surgeons National Surgical Quality Improvement Program database...

It is widely thought that patients with end-stage renal disease who remain vocationally active and/or commercially insured following dialysis initiation have better clinical outcomes and higher quality of life than those who do not. However, scientifically robust data are lacking. Here, we examined whether vocational status (active, N = 1848; inactive, N = 10,001) and, separately, insurance status (commercial, N = 4858; Medicare/self-pay, N = 13,329; Medicaid, N = 3528) were associated with clinical outcomes and Kidney Disease Quality of Life (KDQOL) scores among a cohort of patients who initiated dialysis at a large US dialysis organization during 2015-2016...

This study investigated the purpose and effectiveness of giving outpatients an opportunity to engage in art activities while receiving dialysis treatment. A mixed method study was conducted. 21 semi-structured interviews were conducted with outpatients attending the dialysis unit and 13 surveys of clinicians were completed. The principle reasons to partake in the art activity programme included: to pass time, to relieve boredom, to be creative, to try something new, distraction from concerns, to stay positive and to achieve something new...

Treatment modality education can offer many important benefits to patients and their families. Evidence suggests such education can increase use of home dialysis, reduce catheter use, decrease 90-day mortality, and increase transplantation. While these benefits are encouraging, not all patients are offered options education and when they are, it may not be presented in a way that is immediately applicable to them and their lives. Furthermore, little is known regarding specific characteristics (e.g. format such as group or individual or in-person or online, duration, teaching methods, location, content) of educational programs that are most successful...

Left ventricular assist devices (LVADs) improve survival in patients with advanced heart failure. As LVAD use increases, so do the number of patients with LVADs who also have kidney disease. However, there are only sparse data on how best to care for these patients. This review provides an overview of LVAD principles and indications, including blood pressure assessment and criteria for receipt of both destination and bridge to transplantation LVADs. Following LVAD implantation, kidney function may improve in the short term, particularly if cardiorenal physiology was present; in the longer term, data remain limited...

Dialysis dose is an important determinant of clinical outcomes in patients with end stage renal disease on maintenance dialysis. In clinical practice dialysis dose is monitored at least monthly by urea clearance based on Urea Kinetic Modeling. Online clearance monitoring using effective ionic dialysance (EID) of sodium (Na+ ) is available on some hemodialysis machines. This paper reviews the background, methodology, additional applications, and potential risks associated with EID. Effective ionic dialysance provides a reliable, real-time, noninvasive, and inexpensive measurement of dialysis dose during an ongoing hemodialysis (HD) session to allow interventions and assess the impact of these changes on clearance...

Background: Infections with carbapenem-resistant Enterobacteriaceae (CRE) are increasingly being reported from patients in healthcare settings. They are associated with high patient morbidity, attributable mortality and hospital costs. Patients who are "at-risk" may be carriers of these multidrug-resistant Enterobacteriaceae (MDR-E).The purpose of this guidance is to raise awareness and identify the "at-risk" patient when admitted to a healthcare setting and to outline effective infection prevention and control measures to halt the entry and spread of CRE...

BACKGROUND: Starting dialysis at an advanced age is a clinical challenge and an ethical dilemma. The advantages of starting dialysis at "extreme" ages are questionable as high dialysis-related morbidity induces a reflection on the cost- benefit ratio of this demanding and expensive treatment in a person that has a short life expectancy. Where clinical advantages are doubtful, ethical analysis can help us reach decisions and find adapted solutions. CASE PRESENTATION: Mr...

BACKGROUND: Plasmodium is an obligate intracellular parasite. Apical membrane antigen 1 (AMA1) is the most prominent and well characterized malarial surface antigen that is essential for parasite-host cell invasion, i.e., for sporozoite to invade and replicate within hepatocytes in the liver stage and merozoite to penetrate and replicate within erythrocytes in the blood stage. AMA1 has long served as a potent antimalarial drug target and is a pivotal vaccine candidate. A good understanding of the structure and molecular function of this Plasmodium protein, particularly its involvement in host-cell adhesion and invasion, is of great interest and hence it offers an attractive target for the development of novel therapeutics...

In the past few years, measurement of drug release from pharmaceutical dosage forms has been a focus of extensive research because the release profile obtained in vitro can give an indication of the drug's performance in vivo. Currently, there are no compendial in vitro release methods designed for liposomes owing to a range of experimental challenges, which has created a major hurdle for both development and regulatory acceptance of liposome-based drug products. In this paper, we review the current techniques that are most often used to assess in vitro drug release from liposomal products; these include the membrane diffusion techniques (dialysis, reverse dialysis, fractional dialysis, and microdialysis), the sample-and-separate approach, the in situ method, the continuous flow, and the modified United States Pharmacopeia methods (USP I and USP IV)...

Hemodiafiltration (HDF) is a renal replacement therapy that is based on the principles of diffusion and convection for the elimination of uremic toxins. A significant and increasing number of end-stage renal disease (ESRD) patients are treated with HDF, even in the absence of definite and conclusive survival and anemia treatment data. However, its effects on red blood cell (RBC) physiological features have not been examined in depth. In this study, ESRD patients under regular HDF or conventional hemodialysis (cHD) treatment were examined for RBC-related parameters, including anemia, hemolysis, cell shape, redox status, removal signaling, membrane protein composition, and microvesiculation, in repeated paired measurements accomplished before and right after each dialysis session...

The arteriovenous graft (AVG) is one of the major types of permanent vascular access used to provide hemodialysis. Complications encountered with AVG use include stenosis, infection, thrombosis, and pseudoaneurysm formation. Venous outflow stenosis along with frequent needle cannulation at the same site can lead to breakdown of the graft material, resulting in pseudoaneurysm formation. In the following case, we illustrate common management principles used to treat pseudoaneurysms. While stent-grafts have been utilized for pseudoaneurysm repair, stent-graft usage is not always optimal...

Chronic kidney disease is a condition that affects both the physical and mental abilities of patients. Nursing care is of pivotal importance, in particular when end-stage renal disease (ESRD) patients are concerned, since the quality of the provided care may severely influence the patient's quality of life. This is why it is important to explore patient experiences concerning the rendered care. However, limited up-to-date studies have addressed this issue. The aim of the present study was to stress the experiences of ESRD patients concerning the provided nursing care in the hemodialysis unit at the University Hospital in Heraklion, Crete...

BACKGROUND: The initial part of process development involves extensive screening programs to identify optimal biological systems and cultivation conditions. For a successful scale-up, the operation mode on screening and production scale must be as close as possible. To enable screening under fed-batch conditions, the membrane-based fed-batch shake flask was developed. It is a shake flask mounted with a central feed reservoir with an integrated rotating membrane tip for a controlled substrate release...

The share of peritoneal dialysis (PD) in the spectrum of chronic dialysis has decreased markedly in the Netherlands in the last 15 years. Consequently, the knowledge of nephrologists and nursing staff on PD has declined leading to a negative spiral in which loss of experience resulted in loss of enthusiasm to offer PD to patients and also in less interest in the new PD developments. All these changes took place while the results of PD improved and patient survival was at least similar to that on haemodialysis...
