The Nephrology Quiz and Questionnaire remains an extremely popular session for attendees of the annual Kidney Week meeting of the American Society of Nephrology. During the 2015 meeting the conference hall was once again overflowing with eager quiz participants. Topics covered by the experts included electrolyte and acid-base disorders, glomerular disease, end-stage renal disease and dialysis, and kidney transplantation. Complex cases representing each of these categories together with single-best-answer questions were prepared and submitted by the panel of experts. Before the meeting, training program directors of nephrology fellowship programs and nephrology fellows in the United States answered the questions through an internet-based questionnaire. During the live session members of the audience tested their knowledge and judgment on the same series of case-oriented questions in a quiz. The audience compared their answers in real time using a cell-phone app containing the answers of the nephrology fellows and training program directors. The results of the online questionnaire were displayed, and then the quiz answers were discussed. As always, the audience, lecturers, and moderators enjoyed this highly educational session. This article recapitulates the session and reproduces selected content of educational value for theClinical Journal of the American Society of Nephrologyreaders.

The US pediatric nephrology workforce is poorly characterized. This report describes clinical and nonclinical activities, motivations and disincentives to a career in pediatric nephrology, future workforce needs, trainee recruitment, and possible explanations for personnel shortages. An e-mail survey was sent in 2013 to all identified US-trained or -practicing pediatric nephrologists. Of 504 respondents, 51% are men, 66% are US graduates, and 73% work in an academic setting. About 20% of trained pediatric nephrologists no longer practice pediatric nephrology. Among the 384 respondents practicing pediatric nephrology full or part-time in the United States, the mean work week was 56.1±14.3 hours, with time divided between patient care (59%), administration (13%), teaching (10%), clinical research (9%), basic research (6%), and other medical activities (3%). Most (>85%) care for dialysis and transplantation patients. The median number of weeks annually on call is 16, and 29% work with one or no partner. One-third of US pediatric nephrologists (n=126) plan to reduce or stop clinical nephrology practice in the next 5 years, and 53% plan to fully or partially retire. Almost half the division chiefs (47%) report inadequate physician staffing. Ongoing efforts to monitor and address pediatric nephrology workforce issues are needed.

Advanced training programmes in nephrology should provide broad exposure to all aspects of nephrology. In Australia and New Zealand (ANZ), the Advanced Training Committee in Nephrology oversees training, and recent increases in trainee numbers have led to concern about dilution of experience. To investigate early career paths of nephrologists in ANZ and determine the adequacy of training by comparing self-determined competency and skill relevance among recently graduated nephrologists. In 2015, the Advanced Training Committee in Nephrology administered an online survey during the annual subscription for members of the Australian and New Zealand Society of Nephrology. Nephrologists who were awarded Fellowship after 2002 were invited to participate. The survey was completed by 113 Fellows with 8 respondents excluded (response rate 44.1%). Initial post-Fellowship work included full-time public hospital appointments (34.3%) or undertaking full-time higher research degrees (41.9%). The majority reported securing their desired employment. Respondents indicated adequate training in most clinical skills; however, responses of 'well trained' in home haemodialysis (41.8%), conservative care (42.9%), automated peritoneal dialysis (38.8%), and assessment of kidney transplant recipients (48%) and living kidney donors (34.7%) were less adequate. Although considered highly relevant to current practice, responses of 'well trained' were low for management and research skills, including complaint management (16.3%), private practice management (2%), health system knowledge (14.3%) and regulations (6.1%), ethics approval (23.5%), research funding (11.2%) and quality assurance (26.5%). Nephrology training in ANZ generally meets clinical needs and most secure their desired employment. Training in management and research are areas for improvement. © 2016 Asian Pacific Society of Nephrology.

Survey research is an important research method used to determine individuals' attitudes, knowledge, and behaviors; however, as with other research methods, inadequate reporting threatens the validity of results. This study aimed to describe the quality of reporting of surveys published between 2001 and 2011 in the field of nephrology. The top nephrology journals were systematically reviewed (2001-2011: American Journal of Kidney Diseases, Nephrology Dialysis Transplantation, and Kidney International; 2006-2011: Clinical Journal of the American Society of Nephrology) for studies whose primary objective was to collect and report survey results. Included were nephrology journals with a heavy focus on clinical research and high impact factors. All titles and abstracts were screened in duplicate. Surveys were excluded if they were part of a multimethod study, evaluated only psychometric characteristics, or used semi-structured interviews. Information was collected on survey and respondent characteristics, questionnaire development (e.g., pilot testing), psychometric characteristics (e.g., validity and reliability), survey methods used to optimize response rate (e.g., system of multiple contacts), and response rate. After a screening of 19,970 citations, 216 full-text articles were reviewed and 102 surveys were included. Approximately 85% of studies reported a response rate. Almost half of studies (46%) discussed how they developed their questionnaire and only a quarter of studies (28%) mentioned the validity or reliability of the questionnaire. The only characteristic that improved over the years was the proportion of articles reporting missing data (2001-2004: 46.4%; 2005-2008: 61.9%; and 2009-2011: 84.8%; respectively) (P<0.01). The quality of survey reporting in nephrology journals remains suboptimal. In particular, reporting of the validity and reliability of the questionnaire must be improved. Guidelines to improve survey reporting and increase transparency are clearly needed. Copyright © 2014 by the American Society of Nephrology.

2014-01-01

Chronic kidney disease is a major public health problem globally. Despite this, there are fewer high-quality, high-impact clinical trials in nephrology than other internal medicine specialties, which has led to large gaps in evidence. To address this deficiency, the Australasian Kidney Trials Network, a Collaborative Research Group, was formed in 2005. Since then, the Network has provided infrastructure and expertise to conduct patient-focused high-quality, investigator-initiated clinical trials in nephrology. The Network has not only been successful in engaging the nephrology community in Australia and New Zealand but also in forming collaborations with leading researchers from other countries. This article describes the establishment, development, and functions of the Network. The article also discusses the current and future funding strategies to ensure uninterrupted conduct of much needed clinical trials in nephrology to improve the outcomes of patients affected by kidney diseases with cost-effective interventions.

Onco-nephrology is an evolving subspecialty that focuses on the complex relationships existing between kidney and cancer. In this opinion piece, we propose a 'decalogue of onco-nephrology', in order to highlight the areas where the nephrologist and oncologist should work closely over the ensuing years to provide cutting-edge care for patients afflicted with cancer and kidney disease. The 10 points we have highlighted include (1) acute kidney injury and chronic kidney disease in cancer patients; (2) nephrotoxic effects of anticancer therapy, either traditional chemotherapeutics or novel molecularly targeted agents; (3) paraneoplastic renal manifestations; (4) management of patients nephrectomized for a kidney cancer; (5) renal replacement therapy and active oncological treatments; (6) kidney transplantation in cancer survivors and cancer risk in ESRD patients; (7) oncological treatment in kidney transplant patients; (8) pain management in patients with cancer and kidney disease, (9) development of integrated guidelines for onco-nephrology patients and (10) clinical trials designed specifically for onco-nephrology. Following these points, a multidisciplinary onco-nephrology team will be key to providing outstanding, cutting-edge care in both the acute and chronic setting to these patients. © The Author 2015.

The high prevalence of chronic kidney disease (CKD) in the general population has created a need to coordinate specialised nephrology care and primary care. Although several systems have been developed to coordinate this process, published results are scarce and contradictory. To present the results of the application of a coordinated programme between nephrology care and primary care through consultations and a system of shared clinical information to facilitate communication and improve the criteria for referring patients. Elaboration of a coordinated care programme by the primary care management team and the nephrology department, based on the SEN-SEMFYC consensus document and a protocol for the study and management of arterial hypertension (AHT). Explanation and implementation in primary health care units. A directory of specialists’ consultations was created, both in-person and via e-mail. A continuous training programme in kidney disease and arterial hypertension was implemented in the in-person consultation sessions. The programme was progressively implemented over a three-year period (2007-2010) in an area of 426,000 inhabitants with 230 general practitioners. Use of a clinical information system named Salut en Xarxa that allows access to clinical reports, diagnoses, prescriptions, test results and clinical progression. Improved referral criteria between primary care and specialised nephrology service. Improved prioritisation of visits. Progressive increase in referrals denied by specialists (28.5% in 2009), accompanied by an explanatory report including suggestions for patient management. Decrease in first nephrology outpatient visits that have been referred from primary care (15% in 2009). Family doctors were generally satisfied with the improvement in communication and the continuous training programme. The main causes for denying referral requests were: patients >70 years with stage 3 CKD (44.15%); patients <70 years with stage 3a CKD (19.15%); albumin/creatinine ratio <500 mg/g (12.23%); non-secondary, non-refractory, essential AHT (11.17%). The general practitioners included in the programme showed great interest and no complaints were registered. The consultations improve adequacy and prioritisation of nephrology visits, allow for better communication between different levels of the health system, and offer systematic training for general practitioners to improve the management of nephrology patients. This process allows for referring nephrology patients with the most complex profiles to nephrology outpatient clinics.

Abstract Social media is gaining popularity amongst both medical educators and life-long learners. One of the most popular social media platforms used by the medical community is Twitter, which is popular amongst physicians, students and patients, and particularly in medical societies. Major international and regional societies commonly use Twitter to amplify their reach beyond what their live annual meetings can achieve. There has been a unique and notable effort by Nephrology societies to craft a structured social media strategy that results in the broadest reach to the community of nephrology providers. We report on the first three such experiments performed by three separate nephrology organizations. PMID:29644054

2007-09-01

This paper, which is abstracted from a larger study into the acquisition and exercise of nephrology nursing expertise, aims to explore the role of knowledge in expert practice. Using grounded theory methodology, the study involved 17 registered nurses who were practicing in a metropolitan renal unit in New South Wales, Australia. Concurrent data collection and analysis was undertaken, incorporating participants' observations and interviews. Having extensive nephrology nursing knowledge was a striking characteristic of a nursing expert. Expert nurses clearly relied on and utilized extensive nephrology nursing knowledge to practice. Of importance for nursing, the results of this study indicate that domain-specific knowledge is a crucial feature of expert practice.

The National Institute of Diabetes and Digestive and Kidney Diseases conducted the Kidney Research National Dialogue as an interactive means to formulate and prioritize research goals necessary to address the needs of patients with renal disease. This commentary summarizes the discussion and priorities arising from the training domain of the dialogue and posits three overall strategies to broaden the nephrology research workforce pipeline. The community needs to recruit and provide support for mentors in nephrology, target medical and graduate students earlier in their education for exposure to renal research, and expand the research workforce to include basic scientists from many disciplines as well as under-represented minorities.

The global nephrology workforce: emerging threats and potential solutions!

Sharif, Muhammad U; Elsayed, Mohamed E; Stack, Austin G

2016-02-01

Amidst the rising tide of chronic kidney disease (CKD) burden, the global nephrology workforce has failed to expand in order to meet the growing healthcare needs of this vulnerable patient population. In truth, this shortage of nephrologists is seen in many parts of the world, including North America, Europe, Australia, New Zealand, Asia and the African continent. Moreover, expert groups on workforce planning as well as national and international professional organizations predict further reductions in the nephrology workforce over the next decade, with potentially serious implications. Although the full impact of this has not been clearly articulated, what is clear is that the delivery of care to patients with CKD may be threatened in many parts of the world unless effective country-specific workforce strategies are put in place and implemented. Multiple factors are responsible for this apparent shortage in the nephrology workforce and the underpinning reasons may vary across health systems and countries. Potential contributors include the increasing burden of CKD, aging workforce, declining interest in nephrology among trainees, lack of exposure to nephrology among students and residents, rising cost of medical education and specialist training, increasing cultural and ethnic disparities between patients and care providers, increasing reliance on foreign medical graduates, inflexible work schedules, erosion of nephrology practice scope by other specialists, inadequate training, reduced focus on scholarship and research funds, increased demand to meet quality of care standards and the development of new care delivery models. It is apparent from this list that the solution is not simple and that a comprehensive evaluation is required. Consequently, there is an urgent need for all countries to develop a policy framework for the provision of kidney disease services within their health systems, a framework that is based on accurate projections of disease burden, a full understanding of the internal care delivery systems and a framework that is underpinned by robust health intelligence on current and expected workforce numbers required to support the delivery of kidney disease care. Given the expected increases in global disease burden and the equally important increase in many established kidney disease risk factors such as diabetes and hypertension, the organization of delivery and sustainability of kidney disease care should be enshrined in governmental policy and legislation. Effective nephrology workforce planning should be comprehensive and detailed, taking into consideration the structure and organization of the health system, existing care delivery models, nephrology workforce practices and the size, quality and success of internal nephrology training programmes. Effective training programmes at the undergraduate and postgraduate levels, adoption of novel recruitment strategies, flexible workforce practices, greater ownership of the traditional nephrology landscape and enhanced opportunities for research should be part of the implementation process. Given that many of the factors that impact on workforce capacity are generic across countries, cooperation at an international level would be desirable to strengthen efforts in workforce planning and ensure sustainable models of healthcare delivery.

New media tools such as web 2.0 are increasingly being used in the medical field. RSS feeds, podcasts, blogs, wikis, online social networks and social media have all been proposed as innovative tools for the education and updating of clinicians, nurses, other health workers and medical students because of their ease of access and widespread use. Nephrology is one of the medical fields where these technologies have been successfully applied. Medical journals such as the American Journal Kidney Diseases and the Journal of the American Society of Nephrology, and medical societies such as the American Society of Nephrology, are all using these new and powerful communication tools. In addition, blogs and social networks have been developed to allow physicians to distribute, share and comment medical material concerning issues related to nephrology and kidney disease, including images, videos, slides, scientific abstracts and clinical trials updates. This review provides background information on the evolution of both web 2.0 and the social media and describes some of the most interesting applications of web 2.0 and its correlated tools in the field of nephrology.

Entrustable professional activities (EPAs) are complex tasks representing vital physician functions in multiple competencies, used to demonstrate trainee development along milestones. Managing a nephrology outpatient clinic has been proposed as an EPA for nephrology fellowship training. Retrospective cohort study of nephrology fellow outpatient clinic performance using a previously validated chart audit tool. Outpatient encounter chart audits for training years 2008-2009 through 2012-2013, corresponding to participation in the Nephrology In-Training Examination (ITE). A median of 7 auditors (attending nephrologists) audited a mean of 1,686±408 (SD) charts per year. 18 fellows were audited; 12, in both of their training years. Proportion of chart audit and quality indicator deficiencies. Longitudinal deficiency and ITE performance. Among fellows audited in both their training years, chart audit deficiencies were fewer in the second versus the first year (5.4%±2.0% vs 17.3%±7.0%; P<0.001) and declined between the first and second halves of the first year (22.2%±6.4% vs 12.3%±9.5%; P=0.002). Most deficiencies were omission errors, regardless of training year. Quality indicator deficiencies for hypertension and chronic kidney disease-associated anemia recognition and management were fewer during the second year (P<0.001). Yearly audit deficiencies ≥5% were associated with an ITE score less than the 25th percentile for second-year fellows (P=0.03), with no significant association for first-year fellows. Auditor-reported deficiencies declined between the first and second halves of the year (17.0% vs 11.1%; P<0.001), with a stable positive/neutral comment rate (17.3% vs 17.8%; P=0.6), suggesting that the decline was not due to auditor fatigue. Retrospective design and small trainee numbers. Managing a nephrology outpatient clinic is an EPA. The chart audit tool was used to assess longitudinal fellow performance in managing a nephrology outpatient clinic. Failure to progress may be quantitatively identified and remediated. The tool identifies deficiencies in all 6 competencies, not just medical knowledge, the primary focus of the ITE and the nephrology subspecialty board examination. Published by Elsevier Inc.

Medical student attitudes toward kidney physiology and nephrology: a qualitative study.

Roberts, John K; Sparks, Matthew A; Lehrich, Ruediger W

2016-11-01

Interest in nephrology among trainees is waning in the USA. Early perceptions and attitudes to subject matter can be linked to the quality of pre-clinical curricula. We wanted to explore these attitudes in the setting of modern curriculum redesign. We utilized Q methodology to understand first-year medical student attitudes after an innovative kidney physiology curriculum redesign that focuses on blending multiple learning methods. First-year medical students were invited to take a Q sort survey at the conclusion of a kidney physiology course. Students prioritized statements related to their understanding of kidney physiology, learning preferences, preferred course characteristics, perceived clinical relevance of kidney physiology, and interest in nephrology as a career. Factor analysis was performed to identify different student viewpoints. At the conclusion of our modified course, all students (n = 108) were invited to take the survey and 44 (41%) Q sorts were returned. Two dominant viewpoints were defined according to interest in nephrology. The Potentials are students who understand kidney physiology, perceive kidney physiology as clinically relevant, attend class sessions, utilize videos, and are willing to shadow a nephrologist. The Uninterested are students who are less satisfied with their kidney physiology knowledge, prefer to study alone with a textbook, avoid lectures, and are not interested in learning about nephrology. In an updated renal physiology course, students that use multiple learning methods also have favorable attitudes toward learning kidney physiology. Thus, modern curriculum changes that accommodate a variety of learning styles may promote positive attitudes toward nephrology.

Do e-mail alerts of new research increase knowledge translation? A "Nephrology Now" randomized control trial.

As the volume of medical literature increases exponentially, maintaining current clinical practice is becoming more difficult. Multiple, Internet-based journal clubs and alert services have recently emerged. The purpose of this study is to determine whether the use of the e-mail alert service, Nephrology Now, increases knowledge translation regarding current nephrology literature. Nephrology Now is a nonprofit, monthly e-mail alert service that highlights clinically relevant articles in nephrology. In 2007-2008, the authors randomized 1,683 subscribers into two different groups receiving select intervention articles, and then they used an online survey to assess both groups on their familiarity with the articles and their acquisition of knowledge. Of the randomized subscribers, 803 (47.7%) completed surveys, and the two groups had a similar number of responses (401 and 402, respectively). The authors noted no differences in baseline characteristics between the two groups. Familiarity increased as a result of the Nephrology Now alerts (0.23 ± 0.087 units on a familiarity scale; 95% confidence interval [CI]: 0.06-0.41; P = .007) especially in physicians (multivariate odds ratio 1.83; P = .0002). No detectable improvement in knowledge occurred (0.03 ± 0.083 units on a knowledge scale; 95% CI: -0.13 to 0.20; P = .687). An e-mail alert service of new literature improved a component of knowledge translation--familiarity--but not knowledge acquisition in a large, randomized, international population.

YouTube has emerged as a potential teaching tool. Studies of the teaching potential of YouTube videos have not addressed health care provider (HCP) satisfaction; a necessary prerequisite for any teaching tool. We conducted a 4-month investigation to determine HCP satisfaction with a nephrology-specific YouTube channel. The Nephrology On-Demand YouTube channel was analyzed from January 1 through April 30, 2011. Sixty-minute nephrology lectures at East Carolina University were compressed into 10-minute videos and uploaded to the channel. HCPs were asked to answer a 5-point Likert questionnaire regarding the accuracy, currency, objectivity and usefulness of the digital format of the teaching videos. Means, standard deviations and 2-sided chi-square testing were performed to analyze responses. Over 80% of HCPs considered the YouTube channel to be accurate, current and objective. A similar percentage considered the digital format useful despite the compression of videos and lack of audio. The nephrology-specific YouTube channel has the potential to educate HCPs of various training backgrounds. Additional studies are required to determine if such specialty-specific channels can improve knowledge acquisition and retention.

The likelihood of peritoneal dialysis (PD) utilization following a PD catheter insertion attempt is poorly described. We explored the risk factors for PD nonuse, focusing on the method of PD catheter implantation. This population-based retrospective cohort study employed Ontario administrative health data to identify 3886 predialysis adults who had an incident PD catheter implantation between 2002 and 2010. The impact of the method of catheter implantation including open-surgical (open, n = 1884), surgical-laparoscopic (laparoscopic, n = 1154), nephrology-percutaneous (nephrology, n = 498) and radiology-percutaneous (radiology, n = 350) on rates of PD utilization (defined as four consecutive weeks of PD) was examined. Eighty-three percent of study patients received PD. After adjustment, relative to patients with openly inserted catheters, PD utilization was greater for those with nephrology-inserted catheters [adjusted hazard ratio (aHR) 1.59, 95% confidence interval (CI) 1.29-1.95] and similar for radiology-inserted catheters [aHR 1.16, 95% CI 0.94-1.43] or laparoscopic-inserted catheters [aHR 0.97 (95% CI 0.86-1.09)]. Among PD nonusers, death occurred in 10% of the open group, 6% of the laparoscopic group, 27% of the radiology group and in fewer than 3% of the nephrology group. Sixty-nine percent received hemodialysis in the open group, 63% in the laparoscopic group, 61% in the radiology group and 88% in the nephrology group. Those remaining predialysis comprised 12% of the open group, 22% of the laparoscopic group, 11% of the radiology group and <3% of the nephrology group. Nephrology insertion resulted in lower overall rates of PD nonuse, particularly due to death or remaining predialysis. Greater use may be related to insertion timing, technique or greater commitment on the part of nephrologists to the success of PD. © The Author 2014.

As principal frontline caregivers in the U.S. healthcare system, nurses have tremendous influence over a patient's healthcare experience. A growing body of evidence states that the nursing workforce has a direct impact on healthcare quality. A standardized approach to measuring nursing's contribution to patient care and safety using nursing-sensitive quality indicators assists in examining the extent to which nurses and nursing affect the quality and safety of health care. This article focuses on nursing-sensitive quality indicators and discusses healthcare quality indicators and nursing-sensitive indicators used in the U.S. A summary of the work of the American Nephrology Nurses' Association Task Force on Nephrology Nursing-Sensitive Quality Indicators (NNSQI) and an NNSQI exemplar are provided.

A major challenge facing the nephrology community in the United States is the training of adequate numbers of nephrologists to meet patient care and research needs. There is particular cause for concern because of the increasing incidence and prevalence of patients with chronic kidney disease. Data on the clinical and research nephrology workforce are incomplete or absent. However, the number of such individuals likely is inadequate to meet current and projected needs. To solve these workforce shortages, significant issues with regard to clinical and research training need to be addressed. These include funding of fellowship training, increasing the pipeline of medical students and internal medicine residents, and enhancing interest in nephrology among international and particularly US medical graduates. This review discusses these challenges facing the renal community, with emphasis on the care, prevention, and treatment of chronic kidney disease, and identifies potential pathways to developing solutions.

Nephrology ranks next to last in career choices among US medical school graduates. The American Society of Nephrology established a Workforce Committee to help address this issue. Surveys of US medical students indicate that experiences during kidney pathophysiology courses in the preclerkship years may impact their decision to consider a career in nephrology. In October of 2011, preclinical kidney physiology and pathophysiology course directors at US medical schools were surveyed about teaching methods, curricular content, resources, and institutional support for teaching to identify what worked well and what impairs their teaching efforts. A Listserv of these educators, the American Society of Nephrology Renal Educators Listserv, was used to electronically administer the survey. Course leaders from 62 of 114 (54.4%) surveyed medical schools responded. Most of these educators are nephrologists, but physiologists and other clinicians also lead courses; 60% of course directors noted that lectures are videotaped, resulting in decreased attendance. A range of resources is used: 68% use audience response systems, 16% use the simulation center, and none of the educators indicated use of social media (such as Twitter or Facebook); 50% of respondents receive no remuneration, and 68% receive no full-time equivalent for their efforts. Audience response systems, virtual microscopy, and flash animations were identified as valuable teaching tools. Course directors, during subsequent dialogue on the American Society of Nephrology Renal Educators Listserv, have cited incorporation of case scenarios and integration of clinical exposure during preclinical years as methods that inspired interest. Hopefully, adoption of such approaches will ultimately serve to stimulate interest in nephrology.

Wikipedia, a multilingual online encyclopedia, is a common starting point for patient medical searches. As its articles can be authored and edited by anyone worldwide, the credibility of the medical content of Wikipedia has been openly questioned. Wikipedia medical articles have also been criticized as too advanced for the general public. This study assesses the comprehensiveness, reliability, and readability of nephrology articles on Wikipedia. The International Statistical Classification of Diseases and Related problems, 10th Edition (ICD-10) diagnostic codes for nephrology (N00-N29.8) were used as a topic list to investigate the English Wikipedia database. Comprehensiveness was assessed by the proportion of ICD-10 codes that had corresponding articles. Reliability was measured by both the number of references per article and proportion of references from substantiated sources. Finally, readability was assessed using three validated indices (Flesch-Kincaid grade level, Automated readability index, and Flesch reading ease). Nephrology articles on Wikipedia were relatively comprehensive, with 70.5% of ICD-10 codes being represented. The articles were fairly reliable, with 7.1 ± 9.8 (mean ± SD) references per article, of which 59.7 ± 35.0% were substantiated references. Finally, all three readability indices determined that nephrology articles are written at a college level. Wikipedia is a comprehensive and fairly reliable medical resource for nephrology patients that is written at a college reading level. Accessibility of this information for the general public may be improved by hosting it at alternative Wikipedias targeted at a lower reading level, such as the Simple English Wikipedia. © 2013 Wiley Periodicals, Inc.

Nephrology was previously identified as a subspecialty with few Canadian employment opportunities, and in recent years, fewer trainees are choosing nephrology. The objective of this study is to better understand the current Canadian adult nephrology workforce and the expected workforce trends over the next 5 years. This is an online self-administered survey. This study is set in Canada. Survey participants are Canadian adult nephrologists, including self-identified division heads. The measurements of this study are demographics, training, current practice characteristics, work hours, and projected workforce needs. Survey questions were based on previous workforce surveys. Ethics approval was obtained through the University of Saskatchewan. The survey was piloted in both English and French and modified based on the feedback to ensure that responses accurately reflected the information desired. It was circulated to all identified Canadian nephrologists via an anonymous e-mail link for self-administration. Categorical data was aggregated, and free-text answers were thematically analyzed. Additional descriptive analysis was conducted by all authors. Five hundred ninety-two Canadian nephrologists were contacted and 48 % responded, with representation from all Canadian provinces. One third of the respondents were female, and the largest age cohort was 41-50 years. Most nephrologists are trained in Canada and 61 % completed additional training. The majority of the respondents (69.1 %) began working as a nephrologist immediately upon completion of fellowship training. Younger nephrologists reported more challenges in finding a job. Eighty percent of responding nephrologists were satisfied with their current work hours, 13.1 % will reduce work hours within 3 years, an additional 8.2 % will reduce work hours within 5 years, and a further 14.2 % will reduce work hours within 10 years. Nephrology division heads forecasted the number of clinical and academic nephrologists needed for the next 3 and 5 years. The response rate was 48 %. Forecasted workforce needs are not indicative of guaranteed future positions. This Canadian Society of Nephrology workforce survey demonstrated the current workforce demographics, individual nephrologist future workforce plans, and projected nephrology division requirements for the next 3 and 5 years. Further work will need to be done to refine Canadian nephrology workforce planning with the development of a robust strategy that encompasses both societal and nephrologists' needs with the realities of employment.

Acute kidney injury (AKI) is a common clinical problem associated with adverse outcomes. This study identifies the incidence of AKI in two UK district general hospitals' without on-site renal services and assesses AKI management and level of nephrologist input. The AKIN classification was used to identify 1020 AKI patients over 6 months. Data were collated on patient demographics, AKI management and referral to nephrology and intensive care services. Short/long-term renal outcomes were investigated. Patients were followed up for 14 months post-discharge. Incidence of hospital-based AKI was 6.4%. Mean patient age was 73 years. There was 28.1% acute in-hospital mortality with a further 21.6% 14-month mortality. Only 8.3% of patients were referred to nephrology services for in-hospital review, and only 8.1% had outpatient nephrology follow-up. Compliance with the AKI National Confidential Enquiry into Patient Outcomes and Deaths (NCEPOD) recommendations was poor with 32.8% of patients having renal imaging and 15% of patients having acid-base status assessed. NCEPOD compliance improved with nephrology input. Patients referred to nephrology were likely to be younger with pre-existing CKD and severe AKI. 10.5% of AKI episodes were unrecognized. Forty percent of those with unrecognized AKI, (compared with 15% of recognized AKI) developed de novo or progression of pre-existing CKD. AKI in DGHs is mostly managed without nephrology input. There are significant shortcomings in AKI recognition and management in this setting. This is associated with poor mortality and long-term CKD. This study supports a need to improve the teaching and training of front-line medical staff in identifying AKI. Additionally, implementation of AKI e-alert systems may encourage early recognition and provide a prompt for renal referral.

Biomarkers and surrogate endpoints in kidney disease.

Kidney disease and its related comorbidities impose a large public health burden. Despite this, the number of clinical trials in nephrology lags behind many other fields. An important factor contributing to the relatively slow pace of nephrology trials is that existing clinical endpoints have significant limitations. "Hard" endpoints for chronic kidney disease, such as progression to end-stage renal disease, may not be reached for decades. Traditional biomarkers, such as serum creatinine in acute kidney injury, may lack sensitivity and predictive value. Finding new biomarkers to serve as surrogate endpoints is therefore an important priority in kidney disease research and may help to accelerate nephrology clinical trials. In this paper, I first review key concepts related to the selection of clinical trial endpoints and discuss statistical and regulatory considerations related to the evaluation of biomarkers as surrogate endpoints. This is followed by a discussion of the challenges and opportunities in developing novel biomarkers and surrogate endpoints in three major areas of nephrology research: acute kidney injury, chronic kidney disease, and autosomal dominant polycystic kidney disease.

The past decade has been marked by the increasing use of social media platforms, often on mobile devices. In the nephrology community, this has resulted in the organic and continued growth of individuals interested in using these platforms for education and professional development. Here, we review several social media educational resources used in nephrology education and tools including Twitter, videos, blogs, and visual abstracts. We will also review how these tools are used together in the form of games (NephMadness), online journal clubs (NephJC), interactive learning (GlomCon), and digital mentorship (Nephrology Social Media Collective [NSMC] Internship) to build unique educational experiences that are available globally 24 hours per day. Throughout this discussion, we focus on specific examples of free open-access medical education (FOAMed) tools that provide education and professional growth at minimal or no cost to the user. In addition, we discuss inclusion of FOAMed resource development in the promotion and tenure process, along with potential pitfalls and future directions.

In the year 1967 ProfessorDzrik in cooperation with ProfessorJan Brod founded the Nephrological Section of the Slovak Internal Society and then the postgraduate scientific-research activity in nephrology began. The main topics of his scientific activity, in which he received many priority results, were: Isolation and characteristic of inhibitor of glucose utilisation and of inhibitor of renal gluconeogenesis; Effect of "middle molecular substances, especially in the development of renal insufficiency; Isolation and identification of hippurate and pseudouridine. His publishing activity was manifested in more than 500 scientific papers, several monographs and many chapters in various textbooks and manuals of internal medicine and clinical biochemistry, and more than 1,000 citations. The most important success of Professor Dzrik was the textbook "Nephrology which was published in 2004 and he was its main editor. Rastislav Dzriks impact on the field of Nephrology in Slovakia was manifold. It included his complex work of clinical nephrology, his pedagogical activities, and last but not least his excellent organizing abilities.

In Peru there are different hospitals and university programs for training of specialists in nephrology. To assess the perception of physicians who attend such programs. We carried out a descriptive cross-sectional national-level study in physicians who were in the last two years of nephrology training during February 2012 and who had graduated from it in 2010 and 2011. A self-applied questionnaire was developed along with the Peruvian Society of Nephrology based on international standards. The questionnaire evaluated: mentoring, clinical training, procedures, external rotations, research and global perception. Forty doctors were surveyed nationwide. 82.5% had tutors, 22.5% of them said their support was poor. A 27.5% described their theoretical formation as deficient. The practical training was perceived as acceptable globally; however, improvements in training on peritoneal dialysis and reading kidney transplant biopsies are necessary. A 90% have national external rotations and 65% reported to have an international rotation. In the assessment of research, 77.5% thought this is deficient. In addition, 82.5% believed that residency should last four years. However, 60% reported that their residency training was good. There is a decrease in the positive perception of the aspects studied among residents regarding graduates. The overall perception of nephrology residency training was considered good; however, areas of tutoring, and academic and research activities on average were deficient.

Little is known regarding barriers to guideline adherence in the nephrology community. We set out to identify perceived barriers to evidence-based medicine (EBM) and measurement of continuous quality indicators (CQI) in an international cohort of peritoneal dialysis (PD) practitioners. Subscribers to an online nephrology education site (Nephrology Now) were invited to participate in an online survey. Nephrology Now is a non-profit, monthly mailing list that highlights clinically relevant articles in nephrology. Four hundred and seventy-five physicians supplying PD care participated in an online survey assessing their use of EBM and CQI in their PD practice. Ordinal logistic regression was utilized to determine relationships between baseline characteristics and EBM and CQI practices. The majority of physicians were nephrologists (89.7%), and 50.4% worked in an academic centre. Respondents were from the following geographic regions: 13.5% Canadian, 24% American, 23.8% European, 4.4% Australian, 5.3% South American, 10.7% African and 12.2% Asian. Adherence to PD clinical practice guidelines were generally strong; however, lower adherence was associated with countries with lower healthcare expenditure, not using personal digital assistant (PDA), the longer the physician had been practising and smaller (< 20 patients per centre) PD practice. International variation in guideline adherence may be influenced by a country's healthcare expenditure, physician's PDA use and experience, and size of PD practice which may impact future guideline development and implementation.

This paper, the first of the new feature ''The Classics of Italian Nephrology'', describes the monograph published in 1940 ''Le nefropatie. Manuale per i medici e studenti'' (Renal Diseases. Handbook for Doctors and Students). It was written by Adolfo Ferrata (1880-1946), who is remembered today for his important contributions to the advancement of hematology. The book, which has more than 400 pages and many illustrations, especially of pathologic anatomy, is the product of teamwork involving several pupils and coworkers of Ferrata. It describes all aspects of medical renal diseases known at the time, and from an historical viewpoint represents an interesting testimony of the nephrological practice in Italy in the 1940s.

The unit is currently utilizing hematocrit-based blood volume monitoring on each patient, resulting in improved monitoring in patients achieving their target weight. The nurses expressed confidence in their understanding of the use of hematocrit-based blood volume monitoring. This learning experience provided a vivid look at the importance of fluid management in nephrology nursing. This area should always be included in nephrology nurse competencies and represented in a way that it ignites critical thinking within the nursing professional. It is the responsibility of a professional nurse to stay current in evidence-based practice and continuing education. Professional pride stimulates nephrology nurses to seek new learning experiences to enhance their practice.

The 35th Annual Meeting of the American Society of Nephrology, held in Philadelphia, Pennsylvania, United States (October 30 to November 4, 2002) presented the newest advances in basic and clinical nephrology science. Several presentations and symposia discussed the effects of various interventions and risk factors in clinical outcomes in dialysis patients. The recent evidences of pure red cell aplasia secondary to neutralizing antibodies against erythropoietin were also extensively discussed in a special symposium. Recent advances in the management of calcium phosphorus metabolism and secondary hyperparathyroidism, such as the clinical efficacy and safety of AMG-073, a new calcimimetic agent in the control of hyperparathyroidism in chronic kidney disease patients, or the use of sevelamer or lanthanum carbonate as phosphate binders, were presented. The results in animal models on improved sparing of renal function with rapamycin versus cyclosporin A represent a promising advance in renal transplantation. Finally, the recent discoveries with the newly identified disease gene PKHD1, which causes autosomal recessive polycystic kidney disease, were also presented at the meeting. (c) 2002 Prous Science.

Integrating Quality Improvement Education into the Nephrology Curricular Milestones Framework and the Clinical Learning Environment Review

PubMed Central

Prince, Lisa K.; Little, Dustin J.; Schexneider, Katherine I.

2017-01-01

The Accreditation Council for Graduate Medical Education requires that trainees show progressive milestone attainment in the practice–based learning and systems–based practice competencies. As part of the Clinical Learning Environment Review, sponsoring hospitals must educate trainees in health care quality improvement, provide them with specialty–specific quality data, and ensure trainee participation in quality improvement activities and committees. Subspecialty–specific quality improvement curricula in nephrology training programs have not been reported, although considerable curricular and assessment material exists for specialty residencies, including tools for assessing trainee and faculty competence. Nephrology–specific didactic material exists to assist nephrology fellows and faculty mentors in designing and implementing quality improvement projects. Nephrology is notable among internal medicine subspecialties for the emphasis placed on adherence to quality thresholds—specifically for chronic RRT shown by the Centers for Medicare and Medicaid Services Quality Incentive Program. We have developed a nephrology-specific curriculum that meets Accreditation Council for Graduate Medical Education and Clinical Learning Environment Review requirements, acknowledges regulatory quality improvement requirements, integrates with ongoing divisional quality improvement activities, and has improved clinical care and the training program. In addition to didactic training in quality improvement, we track trainee compliance with Kidney Disease Improving Global Outcomes CKD and ESRD quality indicators (emphasizing Quality Improvement Program indicators), and fellows collaborate on a yearly multidisciplinary quality improvement project. Over the past 6 years, each fellowship class has, on the basis of a successful quality improvement project, shown milestone achievement in Systems-Based Practice and Practice-Based Learning. Fellow quality improvement projects have improved nephrology clinical care within the institution and introduced new educational and assessment tools to the training program. All have been opportunities for quality improvement scholarship. The curriculum prepares fellows to apply quality improvement principals in independent clinical practice—while showing milestone advancement and divisional compliance with Clinical Learning Environment Review requirements.

Nephrology around Europe: organization models and management strategies: Spain.

de Francisco, Angel L M; Piñera, Celestino

The main aim of this report is to present a picture of the current organization of nephrology in Spain. The Spanish health system offers almost universal coverage, a wide variety of services and a high-quality network of hospitals and primary care centers. Spain has a specialized health care training system that is highly developed, highly regulated, with the capacity to provide high-quality training in 54 different specialties. Nephrology is basically a hospital-based specialty. There are no private dialysis patients in Spain. Hemodialysis centers are 40% public, 15% private and 45% run by companies. The National Health System covers 95% of the population, and there is no cost to patients for treatment of renal disease (dialysis and transplant). We observed a clear decrease of nephrology in residents' election rankings, with position 29 out of 47 specialties in 2007. Some of the reasons for this are the complexity of the subject, no clear information at the university, reduction of professional posts and a very good public service with minimal private practice. In Spain, a model of organization for transplantation was adopted based on a decentralized transplant coordinating network. For cadaveric donors, it compares favorably with rates in other Western countries. Living donor transplantation is very low in Spain--just 10% of total renal transplantation activity. New programs due to financial constraints need to include reduced dialysis costs, greater cost-effectiveness of prescriptions, better handling of ethical issues related to the need for using a clinical score of chronic kidney disease patients to make decisions about conservative or renal replacement therapy and an action plan for improvement of organ donation and transplantation. Recovery of skills (acute kidney injury, biopsies, vascular access, etc.), research and advances in autonomous activities (imaging, surgical and medical vascular training, etc.) are some of the future educational paths needed in nephrology. Adequate decisions in the context of economic restrictions need to be discussed for the sustainability of nephrological care.

[Historical archives of Italian nephrology: The history of instrumentation in nephrology. Part I: Theoretical bases].

Timio, M

2002-01-01

Microscopes and artificial kidneys have greatly influenced both diagnosis and therapy of renal diseases. Nonetheless, in tracing the influence of instrumentation on nephrology, as revealed by daily activity, we have to recognise the influence of science upon medical instruments. It is for this reason that, besides strictly clinical factors, the scientific factors that contributed to the development of modern nephrology have received considerable attention. Nobody can use an artificial kidney without bearing in mind the contribution of many segments of science. Each segment has a hypothesis in its historical growth, development and decline. The notion that the advancement of science was made possible by the increasing reliance measurements and other quantitative procedure is hardly a novel one. Moreover, it is rather obvious that the experimental process and the use of instrumentation played an important role in the history of nephrology. Measurements, experiments and the use of instruments were interrelated and represented many phases of the improvements made in diagnosis and therapeutics. Naturally, in the history and epistemology of nephrology instrumentation we find conceptual mistakes and erroneous approaches to the biological reality. However, according to Popper's teachings, mistakes are good for science as they give an extra kick to its growth and development. Medical instrumentation is an assembly of scientific theories; it also controls medical theories and promotes the development of new ones. In addition, it changed our approach to the patient. In the pre-physical era, medical practice was almost entirely an intellectual process based on medical theories that the patient was not expected to understand. In the period of physical examinations the physician included the sensual dimension (oral and visual process) and made direct contact with the patient. In the instrumentation period we experience the third type of examination, in which the physician went back to the position of having less contact with the patient. This separation is reminiscent of the pre-physical diagnosis.

We surveyed physician assistants who work in nephrology to report their experience level, primary employer, salary, job responsibilities, and job satisfaction. Additional data were obtained from the Nephrology Manpower Study. The 67 responding physician assistants of 97 surveyed have 10.8 +/- 6.5 years (mean +/- standard deviation) total experience (6.2 +/- 5.0 years in nephrology). Typically, nephrologists (56.1%) or hospitals (30.3%) employ them. The majority (74%) earn $49,999 to $75,000; 79.1% work in outpatient units, 52.4% in inpatient units, 52.4% in hospitals, 43.3% in outpatient offices, and 23.9% in transplant units. In outpatient units, they manage 111 +/- 111 patients, mostly in free-standing (71.1%), for-profit (69.7%), corporately owned (87.3%) units in urban (80%) or suburban (18%) areas. Most (>85%) manage all dialysis- and nondialysis-related problems, including health maintenance; 84.3% are contacted first by staff, and 78% see patients more often than physicians. Of nephrologists who responded to the Manpower Study, 8.9% work with physician assistants and 20.7% work with nurse practitioners. Nephrologists in academic practice or private nephrology groups are more likely to use physician assistants (P < 0.05) and nurse practitioners (P < 0.005) than those in solo practice or multispecialty groups. Nephrologists with physician assistants (33.8 +/- 19.5 v 41.7 +/- 16.8 h/wk) or nurse practitioners (35.8 +/- 18.1 v 42.7 +/- 16.9 h/wk) tended to spend less time in direct patient care than those without physician extenders (P < 0.001). Nephrologists with renal fellows, however, spent the least time of all in direct patient care (30.0 +/- 15.9 v 47.3 +/- 14.9 h/wk; P < 0.001). Physician assistants can perform nearly all the medical tasks in dialysis units. They may offer one approach to providing effective and complete care for patients if nephrology manpower becomes limited.

An effective workforce is essential for delivery of high-quality chronic disease care. Low-income nations are challenged by a dearth and/or maldistribution of an essential workforce required for all chronic disease care including chronic kidney disease (CKD). Nephrology education and training in developed countries have grown at pace with the technological advancement in the practice of medicine in order to meet the standards required of kidney health professionals towards high-quality, patient-centered medical care. The standards designed by institutions and/or professional societies, such as Royal Colleges and Medical Councils in high-income nations with well-developed health systems and infrastructures, are often not easily translatable to issues critical to nephrology practice in low-income nations. Little or no guidance is provided on common nephrological issues of regional nature or pertaining to ethnic minorities and disadvantaged groups living in those countries. There is an emergent need for a training curriculum that meets the needs and peculiarities of the developing nations, and this needs to leverage on the existing and well-validated systems of training across the globe. We evaluated nephrology training programs across 25 upper-middle and high-income nations to identify best practices and opportunities for adoption in low-income nations. We reviewed training guidelines from major professional societies on content and process of training. There are similarities and differences in structure, content, and process of training programs across countries, and there are clearly adoptable concepts/frameworks for application in low-income nations. We provide recommendations and a strategic plan for the future focus of nephrology training in the developing world to align with current trends in technological advancement and development as well as the need for emphasis on prevention of CKD. The essential competencies (patient- and population--based) required of a nephrologist in a developing world setting are outlined with practical measures and an action plan for adoption.

Nephrology and astrology--is there a link?

Astrologers presume a link between the susceptibility of particular organs to disease and signs of the Zodiac. A simple test of the positive connection between renal disease and the sign of Libra was undertaken by studying the birth dates of consecutive nephrology in-patient admissions. No significant link was found on analysis, thus disproving the traditional astrologers' claims.

Despite the increasing prevalence of CKD in the United States, there is a declining interest among United States medical graduates in nephrology as a career choice. Effective programs are needed to generate interest at early educational stages when career choices can be influenced. The Kidney Disease Screening and Awareness Program (KDSAP) is a novel program initiated at Harvard College that increases student knowledge of and interest in kidney health and disease, interest in nephrology career paths, and participation in kidney disease research. This model, built on physician mentoring, kidney screening of underserved populations, direct interactions with kidney patients, and opportunities to participate in kidney research, can be reproduced and translated to other workforce-challenged subspecialties.

While metacognitive strategies can mitigate premature closure in inexperienced learners, these are rarely studied in experienced physicians. Our objective here was to evaluate the effect of analytic information processing on diagnostic performance of nephrologists and nephrology residents. Methods We asked nine nephrologists and six nephrology residents at the University of Calgary and Glasgow University to diagnose ten nephrology cases. We provided presenting features along with contextual information, after which we asked for an initial diagnosis. We then primed participants to use either hypothetico-deductive reasoning or scheme-inductive reasoning to analyze the remaining case data and generate a final diagnosis. Results After analyzing initial hypotheses, both nephrologists and residents improved the accuracy of final diagnoses (31.1% vs. 65.6%, p < 0.001, and 40.0% vs. 70.0%, p < 0.001, respectively). We found a significant interaction between experience and analytic processing strategy (p = 0.02): nephrology residents had significantly increased odds of diagnostic success when using scheme-inductive reasoning (odds ratio [95% confidence interval] 5.69 [1.59, 20.33], p = 0.07), whereas the performance of experienced nephrologists did not differ between strategies (odds ratio 0.57 [0.23, 1.39], p = 0.20). Discussion Experienced nephrologists and nephrology residents can improve their performance by analyzing initial diagnostic hypotheses. The explanation of the interaction between experience and the effect of different reasoning strategies is unclear, but may relate to preferences in reasoning strategy, or the changes in knowledge structure with experience.

[Nephrology as seen by nephrologists. An introspective investigation into the history and future of the professional community].

The professional community of nephrologists is going through a phase of ''rethinking'' the discipline that sees the role of nephrologists in an uncertain position between inpatient and outpatient care. A comparison of opinions within the community is necessary to understand what could be the future position of nephrology in the Italian healthcare system. In June 2009 a questionnaire was distributed among the members of the Italian Nephrology Society (SIN) to collect (i) their professional biographies and (ii) their opinion on the state of the art of nephrology, (iii) the working context in which they operate, (iv) the likely sources of change, and (v) the prospects for the development of the field. In October 2009 the respondents were 506, a sufficiently representative sample of the national population of nephrologists. One of the main findings was a lack of consensus about the clinical practice for the treatment of CKD. In particular, there was no general agreement about the stage of CKD at which the patient should enter the exclusive care of the nephrologist. Opinions were less divergent on (i) departmentalization phenomena, (ii) the outsourcing of dialysis services, and (iii) the future prospects of the specialty. In order to pursue common goals for the development of the discipline, the internal relations of the professional community should be strengthened both in terms of sharing clinical experience and defining the roles of clinicians within the community. The involvement of young nephrologists in the definition of strategies for the positioning of nephrology in the Italian healthcare system might also be considered a priority.

Nephrology fellows often face difficult conversations about dialysis initiation or withdrawal but are frequently unprepared for these discussions. Despite evidence that communication skills are teachable, few fellowship programs include such training. A communication skills workshop for nephrology fellows (NephroTalk) focused on delivering bad news and helping patients define care goals, including end-of-life preferences. This 4-hour workshop, held in October and November 2011, included didactics and practice sessions with standardized patients. Participants were nephrology fellows at Duke University and the University of Pittsburgh (n=22). Pre- and post-workshop surveys evaluated efficacy of the curriculum and measured changes in perceived preparedness on the basis on workshop training. Overall, 14% of fellows were white and 50% were male. Less than one-third (6 of 22) reported prior palliative care training. Survey response rate varied between 86% and 100%. Only 36% (8 of 22) and 38% (8 of 21) of respondents had received structured training in discussions for dialysis initiation or withdrawal. Respondents (19 of 19) felt that communication skills were important to being a "great nephrologist." Mean level of preparedness as measured with a five-point Likert scale significantly increased for all skills (range, 0.5-1.14; P<0.01), including delivering bad news, expressing empathy, and discussing dialysis initiation and withdrawal. All respondents (21 of 21) reported they would recommend this training to other fellows. NephroTalk is successful for improving preparedness among nephrology fellows for having difficult conversations about dialysis decision-making and end-of-life care.

In 2012, the international nephrology organization Kidney Disease Improving Global Outcomes (KDIGO) released recommendations for nephrology referral for chronic kidney disease (CKD) patients. The feasibility of adhering to these recommendations is unknown. We conducted a retrospective analysis of the primary care population at Brigham and Women's Hospital (BWH). We translated referral recommendations based upon serum creatinine, estimated glomerular filtration rate (eGFR), and albuminuria into a set of computable criteria in order to project referral volume if the KDIGO referral recommendations were to be implemented. Using electronic health record data, we evaluated each patient using the computable criteria at the times that the patient made clinic visits in 2013. We then compared the projected referral volume with baseline nephrology clinic volume. Out of 56,461 primary care patients at BWH, we identified 5593 (9.9%) who had CKD based on albuminuria or estimated GFR. Referring patients identified by the computable criteria would have resulted in 2240 additional referrals to nephrology. In 2013, this would represent a 38.0% (2240/5892) increase in total nephrology patient volume and 67.3% (2240/3326) increase in new referral volume. This is the first study to examine the projected impact of implementing the 2012 KDIGO referral recommendations. Given the large increase in the number of referrals, this study is suggestive that implementing the KDIGO referral guidelines may not be feasible under current practice models due to a supply-demand mismatch. We need to consider new strategies on how to deliver optimal care to CKD patients using the available workforce in the U.S. health care system.

Given the public health challenge and burden of chronic kidney disease, the Italian Society of Nephrology (SIN) promoted a census of the renal and dialysis units to analyse structural and human resources, organizational aspects, activities and workload referring to the year 2014. An online questionnaire, including 64 items exploring structural and human resources, organization aspects, activities and epidemiological data referred to 2014, was sent to chiefs of any renal or dialysis unit. 615 renal units were identified. From these 615 units, 332 were public renal centres (of which 318 centres answered to the census) and 283 were private dialysis centres (of which 113 centres answered to the census). The results show 6 public renal units pmp. Renal biopsies were 4624 (81 pmp). The nephrology beds are about 41 pmp. There are 7.304 nurses working in HD wards, 1.692 in the nephrology wards and only 613 for outpatients clinics. The benchmark data derived from this census show interesting comparisons between centres, regions and groups of regions. These data realised the clinical management of renal disease in Italy.

This article is dedicated to the current state and prospectives of cell engineering in nephrology from the point of view of military medicine. The review is based on publications from January 1, 2014, to June 1, 2015, and consists of two parts. In the first part the main directions of the cell engineering development are mentioned. The only two clinical trials existed in the field are discussed in more detail. The second part deals with prospectives of cell engineering in nephrology. It is shown that currently this field is in the stage of preclinical experimentation. Of the two known clinical trials the first has failed to demonstrate any effectiveness of cell engineering, the second--will be completed only at the end of 2016. Also, the review notes an extraordinary cost of cell engineering experiments in nephrology. The analysis of publications allows to come to a conclusion that the future progress in prevention and treatment of acute kidney injury could go not in the direction of cell engineering but rather non-cell technologies. One of. the practical consequence of such a conclusion is a necessity to continue the improvement of already existing methods of machine renal replacement therapy.

Subsequent entry biologics (SEBs) may soon be a reality in Canadian nephrology practice. Understanding the worldwide experience with these agents will be valuable to Canadian clinicians. To compare the efficacy and safety data between SEBs used in nephrology practice and their reference biologic. Systematic review. Ovid MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, Database of Abstracts of Review of Effects, Cochrane Central Register of Controlled Trials. Adult patients with chronic kidney disease (CKD). Our systematic review follows the process outlined by Cochrane Reviews. For efficacy data, all randomized controlled trials (RCTs), quasi-RCTs and observational trials in nephrology practice were included. For safety data, case series, case reports, review articles in nephrology practice and pharmacovigilance programs were included as well. Only epoetin SEBs trials were published in the literature. Ten studies involving three different epoetin SEBs (epoetin zeta, HX575 and epoetin theta) were included. The mean epoetin dose used did not differ significantly between the SEBs and the reference product. For epoetin zeta and epoetin theta, the mean hemoglobin levels achieved in the studies were similar between the SEBs and the reference epoetin. The HX 575 studies reported a mean absolute change in hemoglobin within the predefined equivalence margin, when compared with the reference biologic. In terms of safety data, 2 cases of pure-red-cell aplasia were linked to the subcutaneous administration of HX 575. Otherwise, the rate of adverse drug reactions was similar when epoetin SEBs were compared with the reference biologic. Our analysis is limited by the paucity of information available on SEB use in nephrology with the exception of epoetin SEBs. Methodological flaw was found in one of the epoetin zeta studies which accounted for 45% of pooled results. Little clinical difference was found between epoetin SEBs and the reference product. Although not deemed clinically important, the financial implication of a possible dose difference between epoetin zeta and reference product should be considered in pharmacoeconomic studies. Ongoing trials are expected to address the risk of pure-red-cell aplasia with HX 575.

In 2012, 27 organizations will initiate participation in the Medicare Shared Savings Program as Accountable Care Organizations. This level of participation reflects the response of Centers for Medicare and Medicaid Services to criticism that the program as outlined in the proposed rule was overly burdensome, prescriptive, and too risky. Centers for Medicare and Medicaid Service made significant changes in the final rule, making the Accountable Care Organization program more attractive to these participants. However, none of these changes addressed the serious concerns raised by subspecialty societies-including the American Society of Nephrology-regarding care of patients with multiple chronic comorbidities and complex and end stage conditions. Virtually all of these concerns remain unaddressed, and consequently, Accountable Care Organizations will require guidance and partnership from the nephrology community to ensure that these patients are identified and receive the individualized care that they require. Although the final rule fell short of addressing the needs of patients with kidney disease, the Centers for Medicare and Medicaid Innovation presents an opportunity to test the potentially beneficial concepts of the Accountable Care Organization program within this patient population. The American Society of Nephrology Accountable Care Organization Task Force developed a set of principles that must be reflected in a possible pilot program or demonstration project of an integrated nephrology care delivery model. These principles include preserving a leadership role for nephrologists, encompassing care for patients with later-stage CKD and kidney transplants as well as ESRD, enabling the participation of a diversity of dialysis provider sizes and types, facilitating research, and establishing monitoring systems to identify and address preferential patient selection or changes in outcomes.

Communication and medicine have evolved together. Internet resources now provide an unprecedented opportunity to provide health assistance to the developing world. The International Society of Nephrology Informatics Commission and National Kidney Foundation cyberNephrology initiative (http://www.cybernephrology.org) have created e-mail discussion groups (e.g., NEPHROL, NEPHKIDS, and so forth) and online texts and web resources (e.g., the Schrier Atlas: http://www.kidneyatlas.org) that are, in many respects, ahead of other areas of medicine. On the other hand, nephrology is quite behind in its embrace of some specific communications initiatives that could benefit emerging nations: the Health InterNetwork Access to Research Initiative program, which provides free full-text access to medical journals and books in poorer countries; the Global Health Network Supercourse, which provides specially designed online lectures for the developing world; and Internet2/Abilene and similar research networks around the world, which provide reliable, guaranteed bandwidth for high-quality Internet videoconferencing as an alternative to face-to-face lectures and meetings. The intent of many educational ventures in nephrology, particularly in the clinical practice guideline realm (National Kidney Foundation Kidney Disease Outcomes Quality Initiative, Kidney Disease Improving Global Outcomes, and so forth), is not just to disseminate information but to change human behavior: physician practice and referral patterns, patient compliance, and so forth. Concepts from the worlds of marketing and entertainment, where the science of changing human behavior is highly evolved, can be used to create high-impact, educational offerings to promote health. They can also be highly beneficial to share Internet educational innovations and future vision across boundaries of medical specialties, which is part of the intent of the cyberMedicine joint venture (http://www.cyber-medicine.org).

Studies of the use of the World Wide Web to obtain medical knowledge have largely focused on patients. In particular, neither the international use of academic nephrology World Wide Web sites (websites) as primary information sources nor the use of search engines (and search strategies) to obtain medical information have been described. Visits ("hits") to the Walter Reed Army Medical Center (WRAMC) Nephrology Service website from April 30, 2000, to March 14, 2001, were analyzed for the location of originating source using Webtrends, and search engines (Google, Lycos, etc.) were analyzed manually for search strategies used. From April 30, 2000 to March 14, 2001, the WRAMC Nephrology Service website received 1,007,103 hits and 12,175 visits. These visits were from 33 different countries, and the most frequent regions were Western Europe, Asia, Australia, the Middle East, Pacific Islands, and South America. The most frequent organization using the site was the military Internet system, followed by America Online and automated search programs of online search engines, most commonly Google. The online lecture series was the most frequently visited section of the website. Search strategies used in search engines were extremely technical. The use of "robots" by standard Internet search engines to locate websites, which may be blocked by mandatory registration, has allowed users worldwide to access the WRAMC Nephrology Service website to answer very technical questions. This suggests that it is being used as an alternative to other primary sources of medical information and that the use of mandatory registration may hinder users from finding valuable sites. With current Internet technology, even a single service can become a worldwide information resource without sacrificing its primary customers.

Chronic Kidney Disease (CKD) and the dialytic treatment cause a significant psychological impact on patients, their families and on the medical-nursing staff too. The psychological aspects linked to the chronic condition of Kidney Disease generate the need to integrated a psychologist into the healthcare team of the Nephrology, Dialysis and Hypertension Operative Unit, in order to offer a specific and professional support to the patient during the different stages of the disease, to their caregivers and to the medical team. The aim of this collaboration project between Nephrology and Psychology is to create a global and integrated healthcare model. It does not give attention simply to the physical dimension of patients affected by CKD, but also to the emotional-affective, cognitive and social dimensions and to the health environment.

Renal Replacement Therapy in Austere Environments

2011-01-01

Myoglobinuric renal failure is the classically described acute renal event occurring in disaster environments—commonly after an earthquake—which most tests the ingenuity and flexibility of local and regional nephrology resources. In recent decades, several nephrology organizations have developed response teams and planning protocols to address disaster events, largely focusing on patients at risk for, or with, acute kidney injury (AKI). In this paper we briefly review the epidemiology and outcomes of patients with dialysis-requiring AKI after such events, while providing greater focus on the management of the end-stage renal disease population after a disaster which incapacitates a pre-existing nephrologic infrastructure (if it existed at all). “Austere” dialysis, as such, is defined as the provision of renal replacement therapy in any setting in which traditional, first-world therapies and resources are limited, incapacitated, or nonexistent.

Approximately 14% of Americans are living with chronic kidney disease (CKD). The prevalence of end-stage renal disease (ESRD), the result of progressing CKD continues to rise by 21,000 per year. Currently, the only antibiotic prophylaxis guidelines for patients with ESRD undergoing dental treatment were published by the AHA in 2003. Presented in three parts, the first and second parts of this study found no consistent protocols amongst U.S. dental schools and U.S. GPRs and AEGDs, respectively. The goal of the third part of the project was to determine the current protocol being used to treat ESRD patients at U.S. nephrology fellowship programs. An 18 multiple-choice question survey was e-mailed to 130 directors of nephrology fellowships within the U.S. regarding renal treatment protocol details and antibiotic prophylaxis for patients with renal disease. Note that, 34.6% of respondents reported having an established renal treatment protocol. For programs with a protocol, 69% of programs reported following AHA guidelines. There is a lack of consistent, established protocols amongst U.S. nephrology fellowships. It is suggested that updated and evidence based guidelines for the safe treatment of patients be developed. © 2016 Special Care Dentistry Association and Wiley Periodicals, Inc.

Pneumocystis jirovecii is responsible for pneumonia in immunocompromised populations. Pneumocystis pneumonia has first been discovered as a common and life-threatening opportunistic infection in HIV-infected patients. The aim of this study is to characterize the epidemiological aspects of Pneumocystis pneumonia and then to highlight an outbreak of this infection in a nephrology unit with molecular tools. A multilocus sequence typing method has been used to study the epidemiology of strains isolated during this episode. From January 2007 to April 2011, 39 cases of P. jirovecii pneumonia have been observed. In two thirds of cases, underlying diseases as transplantations, hematologic or solid malignancies, or immunodepressed treatment were the main risk factors and in one third of cases, there were HIV positive patients. This distribution is due to an outbreak of 13 cases in a nephrology unit, where the MLST resulted in two strains profiles regrouping each one 6 and 4 cases among the 10 available isolates. New categories of risk patients of Pneumocystis infection have emerged with severe clinical manifestations and mostly with a fatal outcome. The origin of the transmission is still unknown but a local transmission has been showed in our nephrology unit. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

The application of radionuclide studies to nephrologic and urologic practice has reached a measurable degree of maturity during the past several years. In spite of this, the utilization of these techniques in many institutions in the United States continues to be far less frequent than one would expect from the clinical advantages. The aim of this editorial is to try to place the role of nuclear medicine in urology and nephrology in perspective. At the present time, in spite of the large number of renal agents that have been developed, there is no practical ideal radiopharmaceutical that can serve asmore » a universal agent. Arbitrarily, one may reduce the chief armamentarium to only four radiopharmaceuticals; technetium-99m DTPA, I-131 OIH (orthoiodohippurate), technetium-99m glucoheptonate and technetium-99m DMSA. These agents are discussed with their relative advantages and disadvantages.« less

Intra-operative hemodialysis during liver transplantation: an expanded role of the nephrology nurse.

Hemodialysis is widely acknowledged as a treatment option to stabilize acute medical conditions where biochemistry management is paramount. One of the most challenging situations is during liver transplantation, when patients with moderate renal dysfunction are likely to become acutely acidotic. For nephrology nurses, this extended role requires increased knowledge, advanced skills, and a high level of communication with unfamiliar team members. With appropriate procedures and a supportive environment, delivering such a service is feasible.

OBSERVATIONAL STUDIES VS. RANDOMIZED CONTROLLED TRIALS: AVENUES TO CAUSAL INFERENCE IN NEPHROLOGY

PubMed Central

Kovesdy, Csaba P; Kalantar-Zadeh, Kamyar

2011-01-01

A common frustration for practicing Nephrologists is the adage that the lack of randomized controlled trials (RCTs) does not allow us to establish causality, but merely associations. The field of Nephrology, like many other disciplines, has been suffering from a lack of RCTs. The view that short of RCTs there is no reliable evidence has hampered our ability to ascertain the best course of action for our patients. However, many clinically important questions in medicine and public health such as the association of smoking and lung cancer are not amenable to RCTs due to ethical or other considerations. Whereas RCTs unquestionably hold many advantages over observational studies, it should be recognized that they also have many flaws that render them fallible under certain circumstances. We provide a description of the various pros and cons of RCTs and of observational studies using examples from the Nephrology literature, and argue that it is simplistic to rank them solely based on pre-conceived notions about the superiority of one over the other. We also discuss methods whereby observational studies can become acceptable tools for causal inferences. Such approaches are especially important in a field like Nephrology where there are myriads of potential interventions based on complex pathophysiologic states, but where properly designed and conducted RCTs for all of these will probably never materialize.

A major obstacle that hinders the implementation of technological solutions in healthcare is the rejection of developed systems by users (healthcare professionals and patients), who consider that they do not adapt to their real needs. (1) To design technological architecture for the telecare of nephrological patients by applying a methodology that prioritises the involvement of users (professionals and patients) throughout the design and development process; (2) to show how users' needs can be determined and addressed by means of technology, increasing the acceptance level of the final systems. In order to determine the main current needs in Nephrology, a group of Spanish Nephrology Services was involved. Needs were recorded through semi-structured interviews with the medical team and questionnaires for professionals and patients. A set of requirements were garnered from professionals and patients. In parallel, the group of biomedical engineers identified requirements for patient telecare from a technological perspective. All of these requirements drove the design of modular architecture for the telecare of peritoneal dialysis and pre-dialysis patients. This work shows how it is possible to involve users in the whole process of design and development of a system. The result of this work is the design of adaptable modular architecture for the telecare of nephrological patients and it addresses the preferences and needs of patient and professional users consulted.

Interest in nephrology has been declining in recent years. Long work hours and a poor work/life balance may be partially responsible, and may also affect a fellowship's educational mission. We surveyed nephrology program directors using a web-based survey in order to define current clinical and educational practice patterns and identify areas for improvement. Our survey explored fellowship program demographics, fellows' workload, call structure, and education. Program directors were asked to estimate the average and maximum number of patients on each of their inpatient services, the number of patients seen by fellows in clinic, and to provide details regarding their overnight and weekend call. In addition, we asked about number of and composition of didactic conferences. Sixty-eight out of 148 program directors responded to the survey (46%). The average number of fellows per program was approximately seven. The busiest inpatient services had a mean of 21.5±5.9 patients on average and 33.8±10.7 at their maximum. The second busiest services had an average and maximum of 15.6±6.0 and 24.5±10.8 patients, respectively. Transplant-only services had fewer patients than other service compositions. A minority of services (14.5%) employed physician extenders. Fellows most commonly see patients during a single weekly continuity clinic, with a typical fellow-to-faculty ratio of 2:1. The majority of programs do not alter outpatient responsibilities during inpatient service time. Most programs (approximately 75%) divided overnight and weekend call responsibilities equally between first year and more senior fellows. Educational practices varied widely between programs. Our survey underscores the large variety in workload, practice patterns, and didactics at different institutions and provides a framework to help improve the service/education balance in nephrology fellowships.

Efforts to improve care of patients with ESRD and the policies that guide those activities depend on evidence-based best practices derived from clinical trials and carefully conducted observational studies. Our review describes this process in the context of the translational research model (bench to bedside to populations), with a particular emphasis on bedside care. We illustrate some of its accomplishments and describe the limitations of the data and evidence supporting policy and practice. Copyright © 2016 by the American Society of Nephrology.

Healthcare providers (HCPs) use online medical information for self-directed learning and patient care. Recently, the mobile internet has emerged as a new platform for accessing medical information as it allows mobile devices to access online information in a manner compatible with their restricted storage. We investigated mobile internet usage parameters to direct the future development of mobile internet teaching websites. Nephrology On-Demand Mobile (NODM) (http://www.nephrologyondemand.org) was made accessible to all mobile devices. From February 1 to December 31, 2010, HCP use of NODM was tracked using code inserted into the root files. Nephrology On-Demand received 15 258 visits, of which approximately 10% were made to NODM, with the majority coming from the USA. Most access to NODM was through the Apple iOS family of devices and cellular connections were the most frequently used. These findings provide a basis for the future development of mobile nephrology and medical teaching tools. PMID:21659443

Saint virgin and martyr Marina (Margarita) of Antioch in Pisidia (255-270) is recognized as the patron saint of kidney sufferers and the protectress of nephrology. Beginning in the 13th century she heals in particular patients suffering from nephropathies, pregnant women having a difficult childbirth, barren women and sickly children. She protects the patients from every side effect and complication. Saint Marina is represented in hagiography as a victor, defeating the dragon satan, holding a hammer or a cross and wearing a belt around her back in the area of kidneys. According to writers, artists and sculptors the belt is the perceivable means of Saint Marina for the miraculous recovery from and healing of kidney diseases. Therefore, kidney sufferers and pregnant women put belts upon her relics for blessing and then wore them. From the Middle Ages and Renaissance and up to the contemporary period Saint Marina (Margarita) was considered the patron saint of kidney sufferers. Justifiably she is recognized by the modern medical world as the protectress of nephrology.

Young people are the future of research, especially in nephrology. The prevalence of young nephrologists within the main scientific European societies varies from the 12% to 34% and the 20% of the ERA-EDTA members are less than 40 years old in 2013. Recently, the ERA-EDTA has launched a new platform, the Young Nephrologists Platform (YNP), which the aim is to become the first modern network of young nephrologists from Europe and beyond. YNP aims at promoting the aggregation of young people through modern communication channels such as social networks, blogs and through the construction of a database collecting information on attitudes and personal experiences of each young nephrologist. A mentorship program, focused and young-oriented clinical courses on hot topics and the direct involvement of young nephrologists in working groups and scientific studies are some of the other interesting initiatives driven by YNP. The future of nephrology belongs to the young and YNP could represent a good springboard for the professional growth of young nephrologists.

There is a paucity of studies on whether early referral (ER) to nephrologist could reduce cardiovascular mortality on dialysis, and the length of pre-dialysis nephrological care needed to reduce mortality on dialysis. A total of 604 consecutive patients who started dialysis between 2001 and 2009 in Senshu region, Osaka, Japan were analyzed. Non-linear associations between mortality and pre-dialysis duration of nephrological care were assessed using restricted cubic spline function, and predictors for death analyzed on Cox modeling. A total of 31.6%, 18.2%, 11.3% and 6.1% of patients had >12, 24, 36 and 48 months of pre-dialysis care, respectively. A total of 258 patients (42.7%) were categorized as ER (≥6 months pre-dialysis duration). During the follow-up period (median, 31.1 months), 218 patients died (cardiovascular, n=70; infection, n=69). Although patients with late referral (LR) had a proxy of inappropriate pre-dialysis care compared with the ER group, Cox multivariate analysis failed to show a favorable association between ER and cardiovascular outcome. In contrast, a deleterious effect of LR on overall survival was observed but was limited only to the first 12 months of dialysis (HR, 1.957; 95% CI: 1.104-3.469; P=0.021), but not observed thereafter. Current pre-dialysis nephrological care may reduce short-term mortality but may not improve cardiovascular mortality after dialysis initiation.

2010-01-01

An acceleration in the professionalization of Italian nurses has taken place in recent years. This pattern, together with the increasing prevalence of kidney diseases and the decreasing number of active nephrologists, makes a new collaborative structure between nurses and nephrologists both possible and welcome. This article describes the recent changes and future prospects of the Italian nursing profession. Observations about nephrology are based on interviews conducted with key opinion leaders of nursing in nephrology and dialysis. Italian nurses have recently acquired a status of professional autonomy. Nursing training is now fully integrated in the university system and nurses have obtained more responsibilities and a higher status within healthcare organizations. Future developments may be related to the internal articulation of the profession, supported by master courses and specialist training. Another possible evolution refers to the ongoing restructuring of the healthcare system with an emphasis on nursing activities and skills rather than medical specialties, which will lead to new and stronger managerial roles for nurses. The increase in the prevalence of kidney diseases and the declining number of nephrologists will result in a change in the distribution and utilization of nephrology services. The professionalization of nurses allows a new work division with a task shift from doctors to nurses. Italian nephrologists should seek a preferential relationship with the nursing profession, also considering the nursing shortage in several regions. Possible means to accomplish this preferential relationship could be, in addition to task shifting, nurses' involvement in research, and support for postgraduate training.

A call to arms: economic barriers to optimal dialysis care.

McFarlane, P A; Mendelssohn, D C

Epidemic growth rates and the enormous cost of dialysis pressure end-stage renal disease (ESRD) delivery systems around the world. Payers of dialysis services can constrain costs through (1) limiting access to dialysis, (2) reducing the quality of dialysis, and (3) placing constraints on modality distribution. In order to secure the necessary resources for ESRD care, we propose that the nephrology community consider the following suggestions: First, future leaders in dialysis should acquire additional advanced training in innovative pathways such as health care economics, business and health care administration, and health care policy. Second, the international nephrology community must strongly engage in ongoing advocacy for accessible, high quality, cost-effective care.Third, efforts should be made to better define and then implement optimal dialysis modality distributions that maximize patient outcomes but limit unnecessary costs. Fourth, industry should be encouraged to lower the unit cost of dialysis, allowing for improved access to dialysis, especially in developing countries. Fifth, research should be encouraged that seeks to identify measures that will reduce dialysis costs but will not impair quality of care. Finally, early referral of patients with progressive renal disease to nephrology clinics, empowerment of informed patient choice of dialysis modality, and proper and timely access creation should be encouraged and can be expected to help limit overall expenditures. Ongoing efforts in these areas by the nephrology community will be essential if we are to overcome the challenges of ESRD growth in this new decade.

Professor Hassouna Ben Ayed is the founder of Tunisian nephrology. He introduced in 1962 the first artificial kidney for the treatment of acute renal failure. In 1963, the first acute peritoneal dialysis was done. Renal biopsy started in 1967 with general pathologists. A special laboratory of renal pathology was set up in 1975 with Pr H. Ben Maïz. Epidemiology of glomerular diseases, when histologically proven, was published [8]. A comprehensive program of chronic hemodialysis was started in 1968 and was developed markedly since 1975 with Pr A. El Matri. An intermittent peritoneal dialysis programme was started in 1982 and CAPD in 1983 by Pr T. Ben Abdallah. The Tunisian renal failure patient association was created in 1982 and the Tunisian society of nephrology in November 1983. A national registry for ESRD treatment is available since 1986. Since this time, the number of patients initiating renal replacement therapy (RRT) for ESRD has increased dramatically due to the extension of acceptance criteria for RRT and the increase of the elderly population. The incidence was 13 pmp in 1986 and 133 pmp in 2008. The prevalence was 48.5 pmp in 1986 and 734 pmp in 2008. From 1971 up to 1986, locally dialysed patients have been transplanted abroad, especially in France. On 4 June 1986, the local transplantation program was started at Charles Nicolle Hospital in Tunis. A national center of organ transplantation was created on 12 June 1995. At the end of 2008, there were 106 nephrologists, 26 residents in nephrology and 253 doctors with a training in hemodialysis during 1 year. In university hospitals, the number of nephrology departments is five, with one unit in an army hospital and two units for pediatric nephrology. Five hospitals perform renal transplantation (Tunis: 2 - Sfax: 1 - Sousse: 1 - Monastir: 1). There are 138 centers of hemodialysis: 39 public, 99 private. Seven thousand and eighty patients were treated by HD, 127 patients underwent renal transplantation. The vast majority of these transplants have been performed using living related donors (103/127). The cost of renal replacement therapy (RRT) is taken in charge by the Ministry of Health and the national security boards. Legislation on HD was promulgated by the Tunisian government, setting rigorous and detailed rules for the implementation of new dialysis centers, as well as for the functioning of already active units (4 August 1986 - 4 April 1998). For transplantation, legislation was promulgated on 25 March 1991. Copyright 2010 Association Société de néphrologie. Published by Elsevier SAS. All rights reserved.

Diseases of the kidneys and genitourinary tract are common health problems that affect people of all ages and demographic backgrounds. In this study, we compared the quantity and quality of nephrological and urological articles published in international journals from the three major regions of China: the mainland (ML), Hong Kong (HK), and Taiwan (TW). Nephrological and urological articles originating from ML, TW, and HK that were published in 61 journals from 1999-2008 were retrieved from the PubMed database. We recorded the numbers of total articles, clinical trials, randomized controlled trials, case reports, impact factors (IF), citations, and articles published in the leading general-medicine journals. We used these data to compare the quantity and quality of publication output from the three regions. The total number of articles increased significantly from 1999 to 2008 in the three regions. The number of articles from ML has exceeded that from HK since 2004, and surpassed that from TW in 2008. Publications from TW had the highest accumulated IF, total citations of articles, and the most articles published in leading general-medicine journals. However, HK publications had the highest average IF. Although ML produced the largest quantity of articles, it exhibited the lowest quality among the three regions. The number of nephrological and urological publications originating from the three major regions of China increased significantly from 1999 to 2008. The annual number of publications by ML researchers exceeded those from TW and HK. However, the quality of articles from TW and HK was higher than that from ML.

In France, the coordinated healthcare circuit means that patients should be referred to specialists, for example nephrologists, by another physician. However, there are no recommendations concerning the reasons justifying the referral to a nephrologist. The main purpose of our study is to describe the motif of first consultations in nephrology in the health area 5 of Brittany. We retrospectively collected medical reports of first consultations by 17 nephrologists in the 4 centers of the study area, during the year 2014. In these letters, we noted the consultation motif, the specialty of the physician who refers the patient, and main characteristics of patients. We included 662 first consultations. The main reason for consultations was chronic kidney disease (68.7%), including chronic renal insufficiency (56.9%), proteinuria (7.3%), microscopic hematuria (3.3%) and searching for chronic kidney disease in the presence of risk factor (1.2%). Other frequent reasons were the follow-up consultation after a pregnancy complicated by preeclampsia (9.5%), urinary lithiasis (5.7%), hypertension (3.8%) and hydroelectrolytic disorder (3.5%). Non-nephrology reasons represent 3.2% of first consultations. Almost all patients have been referred by a physician (99.7%), mainly a general practitioner (71.9%). Nephrology first consultations are realized according to the coordinated healthcare circuit since almost all are requested by another physician. The reasons are adapted to the specialty. The main reason is chronic kidney disease, often already associated with renal insufficiency chronic. Copyright © 2016 Association Société de néphrologie. Published by Elsevier Masson SAS.

After contextualising the generic frameworks of nanotechnology and nanomedicine, the 2disciplines are discussed in the field of Nephrology. The potential downside to nanonephrology is the renal clearance of nanoparticles, the use of which is ever-increasing both for nanomedicinal purposes and in nanofoods. The positive impact of nanotechnology in Nephrology is centred on the development of renal nanodiagnostics for basic renal function studies, the early diagnosis of acute kidney injury, reliable and simple follow-up of chronic kidney disease and the improvement of magnetic resonance imaging. Renal drug nanotherapies comprise an important and dual-faceted area: The protection of drugs and nephrotoxic agents (e.g. antibiotics, antiretrovirals, contrast media, etc.) on the one hand, and the development of new kidney disease medications on the other. Renal 'nanotheranostics' is a promising but little-studied area. The impact of nanostructured supports on renal tissue regeneration is also discussed. The article concludes with a brief analysis of the various nanonephrology perspectives. Copyright © 2018 Sociedad Española de Nefrología. Published by Elsevier España, S.L.U. All rights reserved.

The field of nephrology is actively involved in developing biomarkers and improving models for predicting patients' risks of AKI and CKD and their outcomes. However, some important aspects of evaluating biomarkers and risk models are not widely appreciated, and statistical methods are still evolving. This review describes some of the most important statistical concepts for this area of research and identifies common pitfalls. Particular attention is paid to metrics proposed within the last 5 years for quantifying the incremental predictive value of a new biomarker. Copyright © 2014 by the American Society of Nephrology.

Saliva has a broad diagnostic potential which can be used for detection many pathological conditions including renal dysfunction. In saliva can be measured concentration of urea and creatinine as well as the other uremic markers. Saliva urea nitrogen and creatinine and blood urea and creatinine highly correlated therefore might be used for screening in patients with CKD. Saliva collection is truly non-invasive and is especially suitable for small children and elderly patients. Recently, semiquantitative saliva urea test strip is available. Saliva might become promising dia-gnostic biofluid in nephrological practice.Key words: chronic kidney disease - renal failure - salivary dipstick - salivary markers.

The standardized online curriculum vitae (Curriculum Lattes) of 39 researchers in Medicine receiving grants in the 2006-2008 triennium were included in the analysis. The variables analyzed were: gender, affiliation, time from completion of the PhD program, scientific production, and supervision of undergraduate students, and master's and PhD programs. Males (74.4%) and category 2 grants (56.4%) predominated. The following three Brazilian states are responsible for 90% of the researchers: São Paulo (28; 71.8%); Rio Grande do Sul (4; 10.3%); and Minas Gerais (3; 7.7%). Four institutions are responsible for 70% of the researchers: UNIFESP (14; 36%); USP (8; 20.5%); UFMG (3, 7.7%); and UNICAMP (3; 7.7%). Considering the academic career, the assessed researchers published 3,195 articles in medical journals, with a median of 75 articles per researcher (QI = 52-100). The researchers received a total of 25,923 citations at the database Web of Science®, with a median of 452 citations per researcher (QI = 161-927). The average number of citations per article was 13.8 citations (SD = 11.6). The Southeastern region of Brazil concentrates researchers in Nephrology and Urology. Our study has shown an increase in the scientific production of most researchers in the last five years. By knowing the profile of researchers in Nephrology and Urology, more effective strategies to encourage the scientific production and the demand for resources to finance research projects can be defined.

Develop a consensus report to guide dietetic management of overweight or obese individuals with Chronic Kidney Disease (CKD). Six statements relating weight management in CKD guided a comprehensive review of the literature. A summary of the evidence was then presented at the renal nutrition meeting of the 2016 Asia Pacific Society of Nephrology and Australia and New Zealand Society of Nephrology. Majority agreement was defined as group agreement on a statement of between 50-74%, and consensus was considered ≥ 75% agreement. The recommendations were developed via a mini Delphi process. Two statements achieved group consensus: the current guidelines used by dietitians to estimate energy requirements for overweight and obese people with CKD are not relevant and weight loss medications may be unsafe or ineffective in isolation for those with CKD. One statement achieved group agreement: Meal replacement formulas are safe and efficacious in those with CKD. No agreement was achieved on the statements of whether there is strong evidence of benefit for weight loss prior to kidney transplantation; whether traditional weight loss strategies can be used in those with CKD and if bariatric surgery in those with end stage kidney disease is feasible and effective. There is a limited evidence base to guide the dietetic management of overweight and obese individuals with CKD. Medical or surgical strategies to facilitate weight loss are not recommended in isolation and require a multidisciplinary approach with the involvement of a skilled renal dietitian.

Disaster nephrology: a new concept for an old problem

Sever, Mehmet Sukru; Lameire, Norbert; Van Biesen, Wim; Vanholder, Raymond

2015-01-01

Natural and man-made mass disasters directly or indirectly affect huge populations, who need basic infrastructural help and support to survive. However, despite the potentially negative impact on survival chances, these health care issues are often neglected by the authorities. Treatment of both acute and chronic kidney diseases (CKDs) is especially problematic after disasters, because they almost always require complex technology and equipment, whereas specific drugs may be difficult to acquire for the treatment of the chronic kidney patients. Since many crush victims in spite of being rescued alive from under the rubble die afterward due to lack of dialysis possibilities, the terminology of ‘renal disaster’ was introduced after the Armenian earthquake. It should be remembered that apart from crush syndrome, multiple aetiologies of acute kidney injury (AKI) may be at play in disaster circumstances. The term ‘seismonephrology’ (or earthquake nephrology) was introduced to describe the need to treat not only a large number of AKI cases, but the management of patients with CKD not yet on renal replacement, as well as of patients on haemodialysis or peritoneal dialysis and transplanted patients. This wording was later replaced by ‘disaster nephrology’, because besides earthquakes, many other disasters such as hurricanes, tsunamis or wars may have a negative impact on the ultimate outcome of kidney patients. Disaster nephrology describes the handling of the many medical and logistic problems in treating kidney patients in difficult circumstances and also to avoid post-disaster chaos, which can be made possible by preparing medical and logistic scenarios. Learning and applying the basic principles of disaster nephrology is vital to minimize the risk of death both in AKI and CKD patients. PMID:26034592

The goal of this study was to elucidate how the subspecialty and training history of primary care physicians(PCPs) influence CKD management and medical cooperation in Japan. We conducted a nationwide questionnaire survey on CKD management for PCPs from December 2012 to March 2013. The questionnaire included 32 items about CKD management and medical cooperation. PCPs' subspecialties were categorized as follows: general internal medicine, nephrology, cardiology, diabetology/endocrinology, gastroenterology, pulmonology, neurology, neurosurgery, hematology, collagen disease/rheumatology, allergology. The PCPs' training history of nephrology was classified into three categories: none, experienced, active-nephrologist. Response distributions for each question were compared between the PCPs' subspecialties and the three categories of training history. 2,287 out of 28,200 PCPs (8.1%) of all 47 prefectures responded. The majority (86.5%) of responders were PCPs at clinics, and 90.9% were non-nephrologists. The PCPs' subspecialty influenced the response distributions in the following questions: utilization of the CKD guidebook, urinalysis at the first and follow-up examinations, frequency of blood testing, counselling with eGFR, self-monitoring of blood pressure, prescription and cessation of renin-angiotensin system (RAS) inhibitors, anemia treatment with erythropoiesis stimulating agents (ESA). The PCPs' training history of nephrology had a strong impact on various aspects of CKD management. The PCPs' subspecialties also influenced the responses regarding medical cooperation of CKD: relationship with nephrologists, utilization of critical path, criterion of patient referral, requests for nephrologists, discontent with the nephrologists' response. We elucidated that the PCPs' subspecialty and training history of nephrology substantially influenced CKD management and medical cooperation in Japan. Effective promotion activities to improve CKD management and medical cooperation should be proposed on the basis of these data.

Older adults with advanced chronic kidney disease (CKD) experience functional impairment that can complicate CKD management. Failure to recognize functional impairment may put these individuals at risk of further functional decline, nursing home placement, and missed opportunities for timely goals-of-care conversations. Routine geriatric assessment could be a useful tool for identifying older adults with CKD who are at risk of functional decline and provide contextual information to guide clinical decision-making. Two innovative programs were implemented in the Veterans Health Administration that incorporate geriatric assessment into a nephrology visit. In one program, a geriatrician embedded in a nephrology clinic used standardized geriatric assessment tools with individuals with CKD aged 70 and older (Comprehensive Geriatric Assessment for CKD) (CGA-4-CKD). In the second program, a nephrology clinic used comprehensive appointments for individuals aged 75 and older to conduct geriatric assessments and CKD care (Renal Silver). Data on 68 veterans who had geriatric assessments through these programs between November 2013 and May 2015 are reported. In CGA-4-CKD, difficulty with one or more activities of daily living (ADLs), history of falls, and cognitive impairment were each found in 27.3% of participants. ADL difficulty was found in 65.7%, falls in 28.6%, and cognitive impairment in 51.6% of participants in Renal Silver. Geriatric assessment guided care processes in 45.4% (n = 15) of veterans in the CGA-4-CKD program and 37.1% (n = 13) of those in Renal Silver. Findings suggest there is a significant burden of functional impairment in older adults with CKD. Knowledge of this impairment is applicable to CKD management. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

Nephrologists looking for quick answers to diagnostic clinical questions in MEDLINE can use a range of published search strategies or Clinical Query limits to improve the precision of their searches. We aimed to evaluate existing search strategies for finding diagnostic test accuracy studies in nephrology journals. We assessed the accuracy of 14 search strategies for retrieving diagnostic test accuracy studies from three nephrology journals indexed in MEDLINE. Two investigators hand searched the same journals to create a reference set of diagnostic test accuracy studies to compare search strategy results against. We identified 103 diagnostic test accuracy studies, accounting for 2.1% of all studies published. The most specific search strategy was the Narrow Clinical Queries limit (sensitivity: 0.20, 95% CI 0.13-0.29; specificity: 0.99, 95% CI 0.99-0.99). Using the Narrow Clinical Queries limit, a searcher would need to screen three (95% CI 2-6) articles to find one diagnostic study. The most sensitive search strategy was van der Weijden 1999 Extended (sensitivity: 0.95; 95% CI 0.89-0.98; specificity 0.55, 95% CI 0.53-0.56) but required a searcher to screen 24 (95% CI 23-26) articles to find one diagnostic study. Bachmann 2002 was the best balanced search strategy, which was sensitive (0.88, 95% CI 0.81-0.94), but also specific (0.74, 95% CI 0.73-0.75), with a number needed to screen of 15 (95% CI 14-17). Diagnostic studies are infrequently published in nephrology journals. The addition of a strategy for diagnostic studies to a subject search strategy in MEDLINE may reduce the records needed to screen while preserving adequate search sensitivity for routine clinical use. © 2015 Asian Pacific Society of Nephrology.

Arterial stiffness, as measured by pulse wave velocity (PWV), is an independent predictor of cardiovascular events and mortality. Arterial stiffness increases with age. However, modifiable risk factors such as smoking, BP and salt intake also impact on PWV. The finding of modifiable risk factors may lead to the identification of treatable factors, and, thus, is of interest to practicing nephrologist. We have now studied the prevalence and correlates of arterial stiffness, assessed by PWV, in 191 patients from nephrology outpatient clinics in order to identify modifiable risk factors for arterial stiffness that may in the future guide therapeutic decision-making. PWV was above normal levels for age in 85/191 (44.5%) patients. Multivariate analysis showed that advanced age, systolic BP, diabetes mellitus, serum uric acid and calcium polystyrene sulfonate therapy or calcium-containing medication were independent predictors of PWV. A new parameter, Delta above upper limit of normal PWV (Delta PWV) was defined to decrease the weight of age on PWV values. Delta PWV was calculated as (measured PWV) - (upper limit of the age-adjusted PWV values for the general population). Mean±SD Delta PWV was 0.76±1.60 m/sec. In multivariate analysis, systolic blood pressure, active smoking and calcium polystyrene sulfonate therapy remained independent predictors of higher delta PWV, while age, urinary potassium and beta blocker therapy were independent predictors of lower delta PWV. In conclusion, arterial stiffness was frequent in nephrology outpatients. Systolic blood pressure, smoking, serum uric acid, calcium-containing medications, potassium metabolism and non-use of beta blockers are modifiable factors associated with increased arterial stiffness in Nephrology outpatients.

Compelling evidence indicates that the incidence of chronic kidney disease (CKD) is increasing because of an aging population and a higher prevalence of cardiovascular disease, diabetes, and hypertension. Nutrition management of patients with CKD requires early disease recognition, appropriate interpretation of the markers and stages of CKD, and collaboration with other health care practitioners. Better management of CKD can slow its progression, prevent metabolic complications, and reduce cardiovascular related outcomes. Caring for patients with CKD necessitates specialized knowledge and skills to meet the challenges associated with this growing epidemic. The Academy of Nutrition and Dietetics Renal Dietitians Practice Group and the National Kidney Foundation Council on Renal Nutrition, with guidance from the Academy of Nutrition and Dietetics Quality Management Committee, have updated the 2009 Standards of Practice in Nutrition Care and Standards of Professional Performance as a tool for registered dietitian nutritionists working in nephrology nutrition to assess their current skill levels and to identify areas for additional professional development in this practice area. The Standards of Practice apply to the care of patients/clients with kidney disease. The Standards of Professional Performance consist of six domains of professionalism, including: Quality in Practice, Competence and Accountability, Provision of Services, Application of Research, Communication and Application of Knowledge, and Utilization and Management of Resources. Within each standard, specific indicators provide measurable action statements that illustrate how nephrology nutrition principles can be applied to practice. The indicators describe three skill levels (ie, competent, proficient, and expert) for registered dietitian nutritionists working in nephrology nutrition.

Practicing clinical nephrologists are performing fewer diagnostic kidney biopsies. Requiring biopsy procedural competence for graduating nephrology fellows is controversial. An anonymous, on-line survey of all Walter Reed training program graduates ( n =82; 1985-2017) and all United States nephrology program directors ( n =149; August to October of 2017), regarding kidney biopsy practice and training, was undertaken. Walter Reed graduates' response and completion rates were 71% and 98%, respectively. The majority felt adequately trained in native kidney biopsy (83%), transplant biopsy (82%), and tissue interpretation (78%), with no difference for ≤10 versus >10 practice years. Thirty-five percent continued to perform biopsies (13% did ≥10 native biopsies/year); 93% referred at least some biopsies. The most common barriers to performing biopsy were logistics (81%) and time (74%). Program director response and completion rates were 60% and 77%. Seventy-two percent cited ≥1 barrier to fellow competence. The most common barriers were logistics (45%), time (45%), and likelihood that biopsy would not be performed postgraduation (41%). Fifty-one percent indicated that fellows should not be required to demonstrate minimal procedural competence in biopsy, although 97% agreed that fellows should demonstrate competence in knowing/managing indications, contraindications, and complications. Program directors citing ≥1 barrier or whose fellows did <50 native biopsies/year in total were more likely to think that procedural competence should not be required versus those citing no barriers ( P =0.02), or whose fellows performed ≥50 biopsies ( P <0.01). Almost two-thirds of graduate respondents from a single military training program no longer perform biopsy, and 51% of responding nephrology program directors indicated that biopsy procedural competence should not be required. These findings should inform discussion of kidney biopsy curriculum requirements. Copyright © 2018 by the American Society of Nephrology.

Changing Nephrology Nurses' Beliefs about the Value of Evidence-Based Practice and Their Ability to Implement in Clinical Practice.

A rapidly evolving healthcare environment demands sound research evidence to inform clinical practice and improve patient outcomes. Over the past several decades, nurses have generated new knowledge by conducting research studies, but it takes time for this evidence to be implemented in practice. As nurses strive to be leaders and active participants in healthcare redesign, it is essential that they possess the requisite knowledge and skills to engage in evidence-based practice (EBP). Professional nursing organizations can make substantial contributions to the move healthcare quality forward by providing EBP workshops similar to those conducted by the American Nephrology Nurses'Association.

Established as a method to study anatomic changes, such as renal tumors or atherosclerotic vascular disease, magnetic resonance imaging (MRI) to interrogate renal function has only recently begun to come of age. In this review, we briefly introduce some of the most important MRI techniques for renal functional imaging, and then review current findings on their use for diagnosis and monitoring of major kidney diseases. Specific applications include renovascular disease, diabetic nephropathy, renal transplants, renal masses, acute kidney injury and pediatric anomalies. With this review, we hope to encourage more collaboration between nephrologists and radiologists to accelerate the development and application of modern MRI tools in nephrology clinics.

ABSTRACT Hospitalists and primary care physicians encounter renal disease daily. Although most cases of acute kidney injury (AKI) are secondary to dehydration and resolve by giving fluids, many cases of AKI are due to not uncommon but unfamiliar causes needing nephrology evaluation. Common indications to consult a nephrologist on an emergency basis include hyperkalemia or volume overload in end stage renal disease patients (ESRD). Other causes of immediate consultation are cresenteric glomerulonephritis / rapidly progressive glomerulonephritis in which renal prognosis of the patient depends on timely intervention. The following evidence-based key information could improve patient care and outcomes. Abbreviations: AKI: Acute kidney injury ESRD: End stage renal disease patients PMID:28638567

Microelectromechanical Systems and Nephrology: The Next Frontier in Renal Replacement Technology

PubMed Central

Kim, Steven; Roy, Shuvo

2013-01-01

Microelectromechanical systems (MEMS) is playing a prominent role in the development of many new and innovative biomedical devices, but remains a relatively underutilized technology in nephrology. The future landscape of clinical medicine and research will only see further expansion of MEMS based technologies in device designs and applications. The enthusiasm stems from the ability to create small-scale device features with high precision in a cost effective manner. MEMS also offers the possibility to integrate multiple components into a single device. The adoption of MEMS has the potential to revolutionize how nephrologists manage kidney disease by improving the delivery of renal replacement therapies and enhancing the monitoring of physiologic parameters. To introduce nephrologists to MEMS, this review will first define relevant terms and describe the basic processes used to fabricate MEMS devices. Next, a survey of MEMS devices being developed for various biomedical applications will be illustrated with current examples. Finally, MEMS technology specific to nephrology will be highlighted and future applications will be examined. The adoption of MEMS offers novel avenues to improve the care of kidney disease patients and assist nephrologists in clinical practice. This review will serve as an introduction for nephrologists to the exciting world of MEMS. PMID:24206604

The analytical accounting is a countable technique directed to the evaluation, by means of pre-established criteria of distribution, of the internal economy of the hospital, in order to know the effectiveness and efficiency of Clinical Units. The aim of this study was to analyze the activity and costs of the Nephrology Department of General Hospital of Castellón. Activity of Hospitalization and Ambulatory Care, during 2003 was analysed. Hospitalization discharges were grouped in DGR and the costs per DGR were determinated. Total costs Hospitalisation and Ambulatory Care were 560.434,9 and 146.317,8 Euros, respectively. And the costs of one stay, one first outpatient visit and maintenance visit were 200, 63, and 31,6 Euros, respectively. Eighty per cent of the discharges were grouped in 9 DGR and DRG number 316 (Renal Failure) represented 30% of the total productivity. Costs of DGR 316 were 3.178,2 Euros and 16% represented laboratory cost and costs of diagnostic or therapeutic procedures. With introduction of analytical accounting and DGR system, the Nephrology Departments can acquire more full information on the results and costs of treatment. These techniques permits to improve the financial and economic performance.

Innovation in kidney diseases is not commensurate with the effect of these diseases on human health and mortality or innovation in other key therapeutic areas. A primary cause of the dearth in innovation is that kidney diseases disproportionately affect a demographic that is largely disenfranchised, lacking sufficient advocacy, public attention, and funding. A secondary and likely consequent cause is that the existing infrastructure supporting nephrology research pales in comparison with those for other internal medicine specialties, especially cardiology and oncology. Citing such inequities, however, is not enough. Changing the status quo will require a coordinated effort to identify and redress the existing deficits. Specifically, these deficits relate to the need to further develop and improve the following: understanding of the disease mechanisms and pathophysiology, patient engagement and activism, clinical trial infrastructure, and investigational clinical trial designs as well as coordinated efforts among critical stakeholders. This paper identifies potential solutions to these barriers, some of which are already underway through the Kidney Health Initiative. The Kidney Health Initiative is unique and will serve as a current and future platform from which to overcome these barriers to innovation in nephrology.

Alternatives to the traditional parallel-group trial design may be required to answer clinical questions in special populations, rare conditions, or with limited resources. N-of-1 trials are a unique trial design which can inform personalized evidence-based decisions for the patient when data from traditional clinical trials are lacking or not generalizable. A concise overview of factorial design, cluster randomization, adaptive designs, crossover studies, and n-of-1 trials will be provided along with pertinent examples in nephrology. The indication for analysis strategies such as equivalence and noninferiority trials will be discussed, as well as analytic pitfalls. Copyright © 2016 National Kidney Foundation, Inc.

In cases of chronic renal insufficiency, successful kidney transplantation is the method of choice to restore patients' health, well-being and physical fitness. The interdisciplinary collaboration of nephrologists and transplant surgeons has always been a prerequisite for the successful pre-, peri- and post-transplant care of renal transplant patients. The same holds true for liver transplant patients. Here the nephrologist is often involved in cases requiring pre- or post-transplant dialysis as well as in decision making for combined liver-kidney transplantation. This review focuses on nephrological aspects in patient care before and after kidney and liver transplantation. Georg Thieme Verlag KG Stuttgart · New York.

Nephrologic Impact of Hurricanes Katrina and Rita in Areas Not Directly Affected.

PubMed

Dossabhoy, Neville R; Qadri, Mashood; Beal, Lauren M

2015-01-01

Hurricanes Katrina and Rita resulted in enormous loss of life and disrupted the delivery of health care in areas affected by them. In causing mass movements of patients, natural disasters can overwhelm the resources of nephrology communities in areas not suffering direct damage. The following largely personal account evaluates the impact these hurricanes had upon the nephrology community, patients and health care providers alike, in areas not directly affected by the storms. Mass evacuation of hundreds of dialysis patients to surrounding areas overwhelmed the capacity of local hemodialysis centers. Non-availability of medical records in patients arriving without a supply of their routine medications led to confusion and sub-optimal treatment of conditions such as hypertension and congestive heart failure. Availability of cadaveric organs for transplantation was reduced in the surrounding areas, as the usual lines of communication and transportation were severed for several weeks. All of these issues led to prolong waiting times for patients on the transplant list. The hurricanes severely disrupted usual supply lines of medications to hospitals; certain rare conditions may be seen in higher numbers as a result of the shortages induced. We present the interesting surge in cases of acute kidney injury secondary to use of intravenous immune globulin.

The Nephrologist’s Tumor: Basic Biology and Management of Renal Cell Carcinoma

PubMed Central

Hu, Susie L.; Chang, Anthony; Perazella, Mark A.; Okusa, Mark D.; Jaimes, Edgar A.

2016-01-01

Kidney cancer, or renal cell carcinoma (RCC), is a disease of increasing incidence that is commonly seen in the general practice of nephrology. However, RCC is under-recognized by the nephrology community, such that its presence in curricula and research by this group is lacking. In the most common form of RCC, clear cell renal cell carcinoma (ccRCC), inactivation of the von Hippel–Lindau tumor suppressor is nearly universal; thus, the biology of ccRCC is characterized by activation of hypoxia-relevant pathways that lead to the associated paraneoplastic syndromes. Therefore, RCC is labeled the internist’s tumor. In light of this characterization and multiple other metabolic abnormalities recently associated with ccRCC, it can now be viewed as a metabolic disease. In this review, we discuss the basic biology, pathology, and approaches for treatment of RCC. It is important to distinguish between kidney confinement and distant spread of RCC, because this difference affects diagnostic and therapeutic approaches and patient survival, and it is important to recognize the key interplay between RCC, RCC therapy, and CKD. Better understanding of all aspects of this disease will lead to optimal patient care and more recognition of an increasingly prevalent nephrologic disease, which we now appropriately label the nephrologist’s tumor.

Managing Disruptive Behavior by Patients and Physicians: A Responsibility of the Dialysis Facility Medical Director.

PubMed

Jones, Edward R; Goldman, Richard S

2015-08-07

The Centers for Medicare & Medicaid Services' Conditions for Coverage make the medical director of an ESRD facility responsible for all aspects of care, including high-quality health care delivery (e.g., safe, effective, timely, efficient, and patient centered). Because of the high-pressure environment of the dialysis facility, conflicts are common. Conflict frequently occurs when aberrant behaviors disrupt the dialysis facility. Patients, family members, friends, and, less commonly appreciated, nephrology clinicians (i.e., nephrologists and advanced care practitioners) may manifest disruptive behavior. Disruptive behavior in the dialysis facility impairs the ability to deliver high-quality care. Furthermore, disruptive behavior is the leading cause for involuntary discharge (IVD) or involuntary transfer (IVT) of a patient from a facility. IVD usually results in loss of continuity of care, increased emergency department visits, and increased unscheduled, acute dialysis treatments. A sufficient number of IVDs and IVTs also trigger an extensive review of the facility by the regional ESRD Networks, exposing the facility to possible Medicare-imposed sanctions. Medical directors must be equipped to recognize and correct disruptive behavior. Nephrology-based literature and tools exist to help dialysis facility medical directors successfully address and resolve disruptive behavior before medical directors must involuntarily discharge a patient or terminate an attending clinician.

Individuals at risk for chronic kidney disease (CKD), including those with diabetes mellitus and hypertension, are prevalent in primary care physician (PCP) practices. A major systemic barrier to mitigating risk of progression to kidney failure and to optimal care is failure of communication and coordination among PCPs and nephrologists. Quality improvement. Longitudinal practice-level study of tool-based intervention in nephrology practices and their referring PCP practices. 9 PCP and 5 nephrology practices in Philadelphia and Chicago. Tools from Renal Physicians Association toolkit were modified and provided for use by PCPs and nephrologists to improve identification of CKD, communication, and comanagement. CKD identification, referral to nephrologists, communication among PCPs and nephrologists, comanagement processes. Pre- and postimplementation interviews, questionnaires, site visits, and monthly teleconferences were used to ascertain practice patterns, perceptions, and tool use. Interview transcripts were reviewed for themes using qualitative analysis based on grounded theory. Chart audits assessed CKD identification and referral (PCPs). PCPs improved processes for CKD identification, referral to nephrologists, communication, and execution of comanagement plans. Documentation of glomerular filtration rate was increased significantly (P=0.01). Nephrologists improved referral and comanagement processes. PCP postintervention interviews documented increased awareness of risk factors, the need to track high-risk patients, and the importance of early referral. Final nephrologist interviews revealed heightened attention to communication and comanagement with PCPs and increased levels of satisfaction among all parties. Nephrology practices volunteered to participate and recruit their referring PCP practices. Audit tools were developed for quality improvement assessment, but were not designed to provide statistically significant estimates. The use of specifically tailored tools led to enhanced awareness and identification of CKD among PCPs, increased communication between practices, and improvement in comanagement and cooperation between PCPs and nephrologists.

2014-01-01

Background Few studies have evaluated the prevalence of severe hyperkalaemia in unselected patient populations. We identified all episodes of severe hyperkalaemia occurring in 1 year, and described patient demographics, clinical response and outcome. We also assessed junior doctor knowledge of its causes and significance. Materials and methods A retrospective interrogation of the database of the regional biochemical laboratory identified all episodes of severe hyperkalaemia (K≥ 6.5 mmol/L) occurring in 2011. The understanding of trainee doctors of the importance, causes and treatment of severe hyperkalaemia was assessed by structured questionnaire. Results Severe hyperkalaemia was recorded in 433 samples (365 patients) giving a prevalence of 0.11%. Thirty-six per cent of episodes occurred in patients under the care of a nephrologist, who were significantly younger than those not under the care of a nephrologist. In the nephrology cohort, 86% occurred in patients with chronic kidney disease (CKD), the majority of which had CKD Stage 5. In the non-nephrology cohort, only 65% occurred in the context of CKD, which was equally distributed between Stages 3 and 5 CKD. In both patient groups, roughly 50% of episodes occurred in association with acute kidney injury (AKI). Acute mortality (death within 48 h of documented severe hyperkalaemia) was higher in the non-nephrology compared with the nephrology cohort. Time to repeat serum potassium was influenced by the clinical setting with shorter time to repeat for acute care compared with ward settings. Assessment of trainee doctor's knowledge suggested significant deficiencies in relation to severe hyperkalaemia. Conclusions The prevalence of severe hyperkalaemia was low and occurred predominantly in the context of CKD and/or AKI. The majority of episodes occurred in patients not under the care of a nephrologist. Variability in time to repeat serum potassium levels suggested deficiencies in care, and assessment of trainee doctor’s knowledge suggests the need for further educational initiatives to highlight its importance.

Background Internal medicine includes several subspecialties. This study aimed to describe change trend of impact factors in different subspecialties of internal medicine during the past 12 years, as well as the developmental differences among each subspecialty, and the possible influencing factors behind these changes and differences. Methods Nine subspecialties of internal medicine were chosen for comparison. All data were collected from the Science Citation Index Expanded and Journal Citation Reports database. Results (1) Journal numbers in nine subspecialties increased significantly from 1998 to 2010, with an average increment of 80.23%, in which cardiac and cardiovascular system diseases increased 131.2% rank the first; hematology increased 45% rank the least. (2) Impact Factor in subspecialties of infectious disease, cardiac and cardiovascular system diseases, gastroenterology and hepatology, hematology, endocrinology and metabolism increased significantly (p<0.05), in which gastroenterology and hepatology had the largest increase of 65.4%. (3) Journal impact factor of 0–2 had the largest proportion in all subspecialties. Among the journals with high impact factor (IF>6), hematology had the maximum proportion of 10%, nephrology and respiratory system disease had the minimum of 4%. Among the journal with low impact factor (IF<2), journal in nephrology and allergy had the most (60%), while endocrinology and metabolism had the least (40%). There were differences in median number of IF among the different subspecialties (p<0.05), in which endocrinology and metabolism had the highest, nephrology had the lowest. (4) The highest IF had a correlation with journal numbers and total paper numbers in each field. Conclusion The IF of internal medicine journals showed an increasingly positive trend, in which gastroenterology and hepatology increase the most. Hematology had more high IF journals. Endocrinology and metabolism had higher average IF. Nephrology remained the lowest position. Numbers of journals and total papers were associated with the highest IF. PMID:23118973

Early referral and management of high-risk chronic kidney disease may prevent or delay the need for dialysis. Automatic eGFR reporting has increased demand for out-patient nephrology consultations and in some cases, prolonged queues. In Canada, a national task force suggested the development of waiting time targets, which has not been done for nephrology. We sought to describe waiting time for outpatient nephrology consultations in British Columbia (BC). Data collection occurred in 2 phases: 1) Baseline Description (Jan 18-28, 2010) and 2) Post Waiting Time Benchmark-Introduction (Jan 16-27, 2012). Waiting time was defined as the interval from receipt of referral letters to assessment. Using a modified Delphi process, Nephrologists and Family Physicians (FP) developed waiting time targets for commonly referred conditions through meetings and surveys. Rules were developed to weigh-in nephrologists', FPs', and patients' perspectives in order to generate waiting time benchmarks. Targets consider comorbidities, eGFR, BP and albuminuria. Referred conditions were assigned a priority score between 1-4. BC nephrologists were encouraged to centrally triage referrals to see the first available nephrologist. Waiting time benchmarks were simultaneously introduced to guide patient scheduling. A post-intervention waiting time evaluation was then repeated. In 2010 and 2012, 43/52 (83%) and 46/57 (81%) of BC nephrologists participated. Waiting time decreased from 98(IQR44,157) to 64(IQR21,120) days from 2010 to 2012 (p = <.001), despite no change in referral eGFR, demographics, nor number of office hrs/wk. Waiting time improved most for high priority patients. An integrated, Provincial initiative to measure wait times, develop waiting benchmarks, and engage physicians in active waiting time management associated with improved access to nephrologists in BC. Improvements in waiting time was most marked for the highest priority patients, which suggests that benchmarks had an influence on triaging behavior. Further research is needed to determine whether this effect is sustainable.

However, evidence shows that nephrologists receive inadequate training in this area. This study assessed the effectiveness of an educational quality improvement intervention designed to enhance fellows' communication with patients who have advanced kidney disease. Quality improvement project. Full-day annual workshops (2013-2014) using didactics, discussion, and practice with simulated patients. Content focused on delivering bad news, acknowledging emotion, discussing care goals in dialysis decision making when prognosis is uncertain, and addressing dialysis therapy withdrawal and end of life. Participants were first-year nephrology fellows from 2 Harvard-affiliated training programs (N=26). Study assessed the effectiveness of an intervention designed to enhance fellows' communication skills. Primary outcomes were changes in self-reported patient communication skills, attitudes, and behaviors related to discussing disease progression, prognostic uncertainty, dialysis therapy withdrawal, treatments not indicated, and end of life; responding to emotion; eliciting patient goals and values; and incorporating patient goals into recommendations. Surveys measured prior training, pre- and postcourse perceived changes in skills and values, and reported longer term (3-month) changes in communication behaviors, using both closed- and open-ended items. Response rates were 100% (pre- and postsurveys) and 68% (follow-up). Participants reported improvement in all domains, with an overall mean increase of 1.1 (summed average scores: precourse, 2.8; postcourse, 3.9 [1-5 scale; 5 = "extremely well prepared"]; P<0.001), with improvement sustained at 3 months. Participants reported meaningful changes integrating into practice specific skills taught, such as "Ask-Tell-Ask" and using open-ended questions. Self-reported data may overestimate actual changes; small sample size and the programs' affiliation with a single medical school may limit generalizability. A day-long course addressing nephrology fellows' communication competencies across the full course of patients' illness experience can enhance fellows' self-reported skills and practices.

1999-01-01

During the period of the 11th to 17th century, the access of Jews to European universities was restricted and even those who were fortunate enough to be admitted to a university were not awarded a degree at the end of their studies. An exception to this situation was the University of Padua that allowed Jewish students to study and awarded them degrees; indeed 229 physicians graduated from this university between 1409 and 1721. Among these physicians there were many luminaries such as Joseph Del Medigo, Salmon Congeliano and Toviah Cohen. The latter made many contributions to the field of nephrology. In this treatise Maaseh Toviah he discussed uroscopy, kidney function, body fluid homeostasis and obstructive uropathy.

Balancing the Duty to Treat Patients with Ebola Virus Disease with the Risks to Dialysis Personnel.

Evans, Nicholas G

2015-12-07

In 2014, the author was invited to present at the American Society for Nephrology's annual conference in Philadelphia on the ethics of treating patients with Ebola virus disease. The argument was made that the status of health care workers, including nephrologists, was the dominant ethical standard that generated both the duty to treat and the conflicts between this commitment and other ethical commitments that arise in public health emergencies. Conflicts between duty to treat and personal safety, duty to community, and duty to colleagues were illustrated, and suggestions for designing ethics into medical practice were given. This article is a summary of that presentation. Copyright © 2015 by the American Society of Nephrology.

“Advice to the medical students in my service”: the rediscovery of a golden book by Jean Hamburger, father of nephrology and of medical humanities

PubMed Central

2013-01-01

Jean Hamburger (1909–1992) is considered the founder of the concept of medical intensive care (réanimation médicale) and the first to propose the name Nephrology for the branch of medicine dealing with kidney diseases. One of the first kidney grafts in the world (with short-term success), in 1953, and the first dialysis session in France, in 1955, were performed under his guidance. His achievements as a writer were at least comparable: Hamburger was awarded several important literary prizes, including prix Femina, prix Balzac and the Cino del Duca prize (1979), awarded, among others, to Jorge Luis Borges and Konrad Lorenz. Here we would like to offer a selected reading of a “golden” book, “Conseils aux étudiants en medicine de mon service” (“Advice to the Medical Students in my Service”), the first book dedicated to patient-physician relationship in Nephrology, written when dialysis and transplantation were becoming clinical options (1963). The themes include: the central role of the patient, who should be known by name, profession, life style, and not by disease; the importance of the setting of the care; the need for truth-telling and for leaving hope; the role of research not only in the progression of science, but also in the daily clinical practice.

Biosimilars are biologic medicines highly similar to the reference product with no meaningful clinical differences in terms of safety, purity, and potency. All biologic medicines are produced by living cells, resulting in an inherent heterogeneity in their higher order structures and post-translational modifications. In 2010, the US Congress enacted legislation to streamline the approval process for biosimilars of products losing patent protection, with the goal of decreasing costs and improving patient access to therapeutically important but expensive biologic agents. In 2015, the US Food and Drug Administration approved the first biosimilar agent through this pathway. Approval of additional biosimilar agents in the United States, including those used by nephrologists, is anticipated. Given the relative lack of knowledge regarding biosimilars and their approval process and a lack of trust by the nephrology community regarding their safety and efficacy, the National Kidney Foundation conducted a symposium, Introduction of Biosimilar Therapeutics Into Nephrology Practice in the U.S., September 17 to 18, 2015. Issues related to manufacturing, the regulatory approval process, interchangeability, substitution/switching, nomenclature, and clinician and patient awareness and acceptance were examined. This report summarizes the main discussions at the symposium, highlights several controversies, and makes recommendations related to public policy, professional and patient education, and research needs.

Munchausen syndrome by proxy is a persistent fabrication of illness done by a person to another. Renal and urologic forms of this syndrome are not as uncommon as can be thought; a review of all the cases of Munchausen-by-proxy syndrome reveals that 25% of the children had renal or urologic issues. This syndrome can result in a serious diagnostic dilemma for the physicians; knowing this entity can allow early recognition of falsification and limit the physical and psychological damages caused in the victim. In this study, we reviewed the pediatric nephrology cases of Munchausen syndrome by proxy, grouping them through the principal signs of presentation.

Influence of Judaism and Jewish physicians on Greek and Byzantine medicine and their contribution to nephrology.

Massry, S G; Smogorzewski, M; Hazani, E; Shasha, S M

1997-01-01

Both the Old Testament and the Talmud contain a great deal of information on medicine, nephrology, health and disease. The basic premise of early Jewish medicine is based on the notion that disease is due to structural changes in internal organs. This is in contrast to the mythical dogma of humoralism as the basis of health and disease espoused by Hippocrates and Galen. The Old Testament and the Mosaic Codes provided the basis for modern public health and for the hygienic rules practised in our times. The Talmudists laid the foundations for the science of pathology as we know it today. These issues are discussed in detail and the contributions of three prominent medieval physicians (Asaph Judaeus, Isaac Judaeus and Maimonides) are presented.

2005-01-01

The idea that efficacy efficiency, and quality in medicine could not be reached without sorting the huge knowledge of medical and nursing science is very common. Engineers and computer scientists have developed medical software with great prospects for success, but currently these software applications are not so useful in clinical practice. The medical doctor and the trained nurse live the 'information age' in many daily activities, but the main benefits are not so widespread in working activities. Artificial intelligence and, particularly, export systems charm health staff because of their potential. The first part of this paper summarizes the characteristics of 'weak artificial intelligence' and of expert systems important in clinical practice. The second part discusses medical doctors' requirements and the current nephrologic knowledge bases available for artificial intelligence development.

This paper summarizes the impact that wars had on the history of nephrology, both worldwide and in the Ghent Medical Faculty notably on the definition, research and clinical aspects of acute kidney injury. The paper briefly describes the role of 'trench nephritis' as observed both during World War I and II, supporting the hypothesis that many of the clinical cases could have been due to Hantavirus nephropathy. The lessons learned from the experience with crush syndrome first observed in World War II and subsequently investigated over many decades form the basis for the creation of the Renal Disaster Relief Task Force of the International Society of Nephrology. Over the last 15 years, this Task Force has successfully intervened both in the prevention and management of crush syndrome in numerous disaster situations like major earthquakes.

It attracted a total of 927 participants from 18 countries. The full spectrum of hemodialysis was covered with plenary lectures and symposiums delivered by experts from different subspecialties in nephrology starting from the history of hemodialysis, mineral bone disease, microinflammation and advanced techniques in hemodialysis. It was followed by critical care in nephrology, anemia, and nutrition in dialysis. Last but not the least, natural disasters and medical economics in hemodialysis were also discussed extensively. This special article will highlight the authentic contributions and innovative clinical presentations from the meeting. © 2013 International Society for Hemodialysis.

2005-01-01

An outbreak of bacteremia in 20 hemodialysed patients who developed central venous catheter (CVC) infection related to Burkholderia cepacia is reported, introducing medical and professional responsibilities in nephrology units. The cepacia was documented in the blood stream, in the CVC biofilm, in the water supply and in the distribution. This and other confounding factors delayed the identification of the contamination source. Finally, it was isolated, clonally identical to that found in the blood stream, from ammonium chloride solution used to disinfect the skin and distributed in a sterile disposable kit. Burkholderia cepacia was clonally different in blood with respect to water. The possible differing responsibilities in the organizational steps of nephrology activity are discussed.

Public preferences for establishing nephrology facilities in Greenland: estimating willingness-to-pay using a discrete choice experiment.

PubMed

Kjær, Trine; Bech, Mickael; Kronborg, Christian; Mørkbak, Morten Raun

2013-10-01

At present there are no nephrology facilities in Greenland. Greenlandic patients with renal failure needing dialysis thus have to travel to Denmark to obtain treatment. For patients in haemodialysis this necessitates a permanent residence in Denmark. Our study was aimed at examining Greenlanders' preferences for establishing nephrology facilities in Greenland at Queen Ingrid's Hospital in Nuuk, and to estimate the associated change in welfare. Preferences were elicited using a discrete choice experiment (DCE). A random sample of 500 individuals of the general population was sent a postal questionnaire in which they were asked to consider the trade-offs of establishing nephrology facilities in Greenland as opposed to the current situation. This involved trading off the benefits of having such facilities in their home country against the costs of the intervention. Besides including a payment attribute described in terms of incremental tax payment, the DCE included two interventions attributes related to (1) the organisation of labour, and (2) the physical settings of the patients. Respondents succeeded in answering the DCE despite cultural and linguistic disparity. We found that all the included attributes had a significant effect on respondents' choices, and that respondents' answers to the DCE were in keeping with their values as stated in the questionnaire. DCE data was analyzed using a random parameter logit model reparametrized in willingness-to-pay space. The results showed that establishing facilities in Greenland were preferred to the current treatment in Denmark. The welfare estimate from the DCE, at DKK 18.74 million, exceeds the estimated annual costs of establishing treatment facilities for patients with chronic renal failure. Given the estimated confidence interval this result seems robust. Establishing facilities in Greenland therefore would appear to be welfare-improving, deriving positive net benefits. Despite the relatively narrow policy focus, we believe that our findings provide some insight into individuals' preferences for decentralization of public services and on citizens' views of 'self-governance' that go beyond the case of Greenland. More generally, this paper illustrates how DCE can be applied successfully to developing countries with culturally, demographically, and geographically distinct features.

Influence of Nephrologist Care on Management and Outcomes in Adults with Chronic Kidney Disease.

Predialysis nephrology care for adults with late stage chronic kidney disease (CKD) is associated with improved outcomes. Less is known about the effects of nephrology care in earlier stages of CKD. We aimed to evaluate the effect of nephrology care on management of CKD risk factors and complications, CKD progression, incident cardiovascular disease (CVD), and death. This was a prospective cohort study. Participants included 3855 men and women aged 21 to 74 years enrolled in the Chronic Renal Insufficiency Cohort (CRIC) Study with a mean (SD) estimated glomerular filtration rate (eGFR) at entry of 45 (17) ml/min/1.73 m(2), followed for a median of 6.6 years. The main predictor was self-reported prior contact with a nephrologist at study enrollment. Outcomes evaluated included CKD progression (≥ 50 % eGFR loss or end-stage renal disease), incident CVD, and death. Two-thirds (67 %) of the participants reported prior contact with a nephrologist at study enrollment. They were younger, more likely to be male, non-Hispanic white, and had lower eGFR and higher urine protein (p < 0.05). A subgroup with eGFR 30- < 60 ml/min/1.73 m(2) and prior contact with a nephrologist were more likely to receive pharmacologic treatment for CKD-related complications and to report angiotensin-converting enzyme inhibitor or angiotensin receptor blocker (ACEi/ARB) use. After propensity score matching (for reporting prior contact with a nephrologist vs. not) and adjusting for demographic and clinical variables, prior contact with a nephrologist was not significantly associated with CKD progression, incident CVD or death (p > 0.05). One-third of CRIC participants had not seen a nephrologist before enrollment, and this prior contact was subject to age, sex, and ethnic-related disparities. While prior nephrology care was associated with more frequent treatment of CKD complications and use of ACEi/ARB medications, there was neither an association between this care and achievement of guideline-recommended intermediate measures, nor long-term adverse outcomes.

The British Columbia Nephrologists’ Access Study (BCNAS) – a prospective, health services interventional study to develop waiting time benchmarks and reduce wait times for out-patient nephrology consultations

PubMed Central

2013-01-01

Background Early referral and management of high-risk chronic kidney disease may prevent or delay the need for dialysis. Automatic eGFR reporting has increased demand for out-patient nephrology consultations and in some cases, prolonged queues. In Canada, a national task force suggested the development of waiting time targets, which has not been done for nephrology. Methods We sought to describe waiting time for outpatient nephrology consultations in British Columbia (BC). Data collection occurred in 2 phases: 1) Baseline Description (Jan 18-28, 2010) and 2) Post Waiting Time Benchmark-Introduction (Jan 16-27, 2012). Waiting time was defined as the interval from receipt of referral letters to assessment. Using a modified Delphi process, Nephrologists and Family Physicians (FP) developed waiting time targets for commonly referred conditions through meetings and surveys. Rules were developed to weigh-in nephrologists’, FPs’, and patients’ perspectives in order to generate waiting time benchmarks. Targets consider comorbidities, eGFR, BP and albuminuria. Referred conditions were assigned a priority score between 1-4. BC nephrologists were encouraged to centrally triage referrals to see the first available nephrologist. Waiting time benchmarks were simultaneously introduced to guide patient scheduling. A post-intervention waiting time evaluation was then repeated. Results In 2010 and 2012, 43/52 (83%) and 46/57 (81%) of BC nephrologists participated. Waiting time decreased from 98(IQR44,157) to 64(IQR21,120) days from 2010 to 2012 (p = <.001), despite no change in referral eGFR, demographics, nor number of office hrs/wk. Waiting time improved most for high priority patients. Conclusions An integrated, Provincial initiative to measure wait times, develop waiting benchmarks, and engage physicians in active waiting time management associated with improved access to nephrologists in BC. Improvements in waiting time was most marked for the highest priority patients, which suggests that benchmarks had an influence on triaging behavior. Further research is needed to determine whether this effect is sustainable. PMID:23988113

Symptom Management of the Patient with CKD: The Role of Dialysis.

PubMed

Cabrera, Valerie Jorge; Hansson, Joni; Kliger, Alan S; Finkelstein, Fredric O

2017-04-03

As kidney disease progresses, patients often experience a variety of symptoms. A challenge for the nephrologist is to help determine if these symptoms are related to advancing CKD or the effect of various comorbidities and/or medications prescribed. The clinician also must decide the timing of dialysis initiation. The initiation of dialysis can have a variable effect on quality of life measures and the alleviation of uremic signs and symptoms, such as anorexia, fatigue, cognitive impairment, depressive symptoms, pruritus, and sleep disturbances. Thus, the initiation of dialysis should be a shared decision-making process among the patient, the family and the nephrology team; information should be provided, in an ongoing dialogue, to patients and their families concerning the benefits, risks, and effect of dialysis therapies on their lives.

To report the renal structural and functional anomalies in children with multicystic dysplastic kidneys. Retrospective descriptive analysis of 47 children with multicystic dysplastic kidney seen in a pediatric nephrology unit over a period of 6 years. Antenatal diagnosis of multicystic dysplastic kidney was made in 34 (72.3%) patients. On follow up of 31 children for more than 12 months, 21 (68%) had involution, 4 [13%] had non-regression, and 4 (13%) were nephrectomized. Vesico-ureteric reflux (n=13; 28%) was the commonest renal abnormality. The serum creatinine values were higher (P=0.006) in children with contralateral reflux. Sub-nephrotic proteinuria was noted in 9 (29%) and was significantly associated with complete involution (P=<0.023). None of the patients developed hypertension and 2 (6.4%) had renal failure. Close nephrological follow-up is needed in children with multicystic dysplasia of kidneys.

We summarize original research in the field of critical care nephrology accepted or published in 2005 in Critical Care and, when considered relevant or directly linked to this research, in other journals. The articles have been grouped into four categories to facilitate a rapid overview. First, physiopathology, epidemiology and prognosis of acute renal failure (ARF): an extensive review and some observational studies have been performed with the aim of describing aspects of ARF physiopathology, precise epidemiology and long-term outcomes. Second, several authors have performed clinical trials utilizing a potential nephro-protective drug, fenoldopam, with different results. Third, the issue of continuous renal replacement therapies dose has been addressed in a small prospective study and a large observational trial. And fourth, alternative indications to extracorporeal treatment of ARF and systemic inflammatory response syndrome have been explored by three original clinical studies. PMID:16919174

Military nephrology—what a civilian doctor should know

PubMed Central

2011-01-01

This article provides some background on military nephrology in the UK. The primary objective of the Defence Medical Services is the maintenance of operational capability of military personnel. This includes exclusion of nephrological diseases that might reduce renal reserve to a critical level under field conditions, increasing susceptibility to trauma, burns, infection and adverse environmental conditions and increasing the need for renal support. Renal failure potentially compromises not only the patient but also his comrades through reduced staffing and inability to execute the military mission. Safety of weapon systems for which the patient is responsible may be reduced. At forward locations, need for evacuation may put aircraft or vehicles and their crew with medical attendants at unnecessary risk. Regular follow-up and continuity of care are difficult owing to the demands of military life that include frequent postings and deployments. PMID:25984145

Cranberry use among pediatric nephrology patients.

2005-01-01

Recurrent urinary tract infections are common in children, and the use of complementary therapies is common in other children with recurrent illnesses. However, little is known about the use of cranberry products by children with renal disease. We hypothesized that, because cranberry is often used to prevent urinary tract infections (UTI) in adult women, many parents would give it to their children, particularly to children prone to recurrent UTI (rUTI). Anonymous, cross-sectional, self-administered survey of parents of children seen in the pediatric nephrology clinic at Brenner Children's Hospital between June 1, 2004, and August 13, 2004. Of the 117 parents surveyed, the patients' average age was 10.3 years, and 15% reported rUTI as a problem. Overall, 29% of surveyed parents gave cranberry products therapeutically; as expected, use was higher among those with rUTI (65%) than among those with other renal conditions (23%); odds ratio = 6.1 (2.0, 18.4, P < .001); many parents gave cranberry to treat as well as prevent diverse renal problems. Most felt it was beneficial and only 1 parent reported a side effect (nausea). Only 23% of those who used it had discussed cranberry use with their physician. Cranberry is commonly used therapeutically among patients seen in a pediatric nephrology clinic and is perceived as useful by parents, though uncommonly discussed with physicians. Randomized controlled trials are needed to determine the effectiveness of cranberry juice therapy for rUTI in children.

Background: Treatment protocols for childhood nephrotic syndrome are highly variable between providers and care centres. We conducted a qualitative study to understand the complex multilevel processes that lead to practice variation and influence provider management of nephrotic syndrome. Methods: Focus groups with multidisciplinary pediatric nephrology care providers (n = 67) from 10 Canadian pediatric nephrology centres that had more than 1 pediatric nephrologist were conducted between September 2013 and April 2015. Focus group discussions were guided by the Ottawa Model for Research Use. We used a semistructured interview guide to elicit participants' perspectives regarding 1) the work setting and context of the clinical environment, 2) reasons for variation at the provider level and 3) clinical practice guidelines for nephrotic syndrome. Focus group discussions were transcribed and analyzed concurrently with the use of qualitative content analysis. Results: Emerging themes were grouped into 2 categories: centre-level factors and provider-level factors. At the centre level, the type of care model used, clinic structures and resources, and lack of communication and collaboration within and between Canadian centres influenced care variation. At the provider level, use of experiential knowledge versus empirical knowledge and interpretation of patient characteristics influenced provider management of nephrotic syndrome. Interpretation: Centre- and provider-level factors play an important role in shaping practice differences in the management of childhood nephrotic syndrome. Further research is needed to determine whether variation in care is associated with disparities in outcomes. PMID:28592406

Evidence-informed decision making in clinical care and policy in nephrology is undermined by trials that selectively report a large number of heterogeneous outcomes, many of which are not patient centered. The Standardized Outcomes in Nephrology-Hemodialysis (SONG-HD) Initiative convened an international consensus workshop on November 7, 2015, to discuss the identification and implementation of a potential core outcome set for all trials in hemodialysis. The purpose of this article is to report qualitative analyses of the workshop discussions, describing the key aspects to consider when establishing core outcomes in trials involving patients on hemodialysis therapy. Key stakeholders including 8 patients/caregivers and 47 health professionals (nephrologists, policymakers, industry, and researchers) attended the workshop. Attendees suggested that identifying core outcomes required equitable stakeholder engagement to ensure relevance across patient populations, flexibility to consider evolving priorities over time, deconstruction of language and meaning for conceptual consistency and clarity, understanding of potential overlap and associations between outcomes, and an assessment of applicability to the range of interventions in hemodialysis. For implementation, they proposed that core outcomes must have simple, inexpensive, and validated outcome measures that could be used in clinical care (quality indicators) and trials (including pragmatic trials) and endorsement by regulatory agencies. Integrating these recommendations may foster acceptance and optimize the uptake and translation of core outcomes in hemodialysis, leading to more informative research, for better treatment and improved patient outcomes.

Bryan, Lisa; Ibrahim, Tod; Fischer, Michael J.

2014-01-01

Research funding from public and private sources has reached an all-time low. Economic conditions, sequestration, and a trend of low award success rates have created an imbalance between the supply of highly qualified research investigators and the availability of critically necessary research dollars. This grim environment continues to hinder the success of established investigators and deter potential investigators from joining the research workforce. Without action and support of innovative science, the future of the US health care system is in jeopardy, and its leadership role in medical research will decrease. This work discusses the effects of the decline in research funding, the plight of kidney research, and the impact of the American Society of Nephrology Grants Program on scientists. The ASN also calls on the entire nephrology community to rejuvenate the research environment, improve the lives of millions of people with kidney disease, and ultimately, find a cure. PMID:24652790

Exaggerated oxidative stress (OS) is usually considered as a disturbance in regular function of an organism. The excessive levels of OS mediators may lead to major damage within the organism's cells and tissues. Therefore, the OS-associated biomarkers may be considered as new diagnostic tools of various diseases. In nephrology, researchers are looking for alternative methods replacing the renal biopsy in patients with suspicion of chronic kidney disease (CKD). Currently, CKD is a frequent health problem in world population, which can lead to progressive loss of kidney function and eventually to end-stage renal disease. The course of CKD depends on the primary disease. It is assumed that one of the factors influencing the course of CKD might be OS. In the current work, we review whether monitoring the OS-associated biomarkers in nephrology patients can support the decision-making process regarding diagnosis, prognostication and treatment initiation.

Diagnosing kidney disease in the genetic era.

Recent technological improvements have increased the use of genetic testing in the clinic. This review serves to summarize the many practical benefits of genetic testing, discusses various methodologies that can be used clinically, and exemplifies ways in which genetics is propelling the field forward in nephrology. The advent of next-generation sequencing and microarray technologies has heralded an unprecedented number of discoveries in the field of nephrology, providing many opportunities for incorporating genomic diagnostics into clinical care. The use of genetic testing, particularly in pediatrics, can provide accurate diagnoses in puzzling cases, resolve misclassification of disease, and identify subsets of individuals with treatable conditions. Genetic testing may have broad benefits for patients and their families. Knowing the precise molecular etiology of disease can help clinicians determine the exact therapeutic course, and counsel patients and their families about prognosis. Genetic discoveries can also improve the classification of kidney disease and identify new targets for therapy.

This is a report of a combined experience of a nephrologist, who had been previously working for many years in a public hospital, and a business planning manager coming from a financial administration department of a multinational company. The Istituto Clinico Humanitas is a multi-specialist hospital accreditated with the National Health System, containing 473 beds available: 398 inpatient, 28 intensive care and 47 day hospital beds. Human resources include approximately 250 medical doctors, 500 nurses and ancillary workers. In 2002 the hospital treated about 17,500 inpatients, 18,450 day hospital patients, nearly 18,600 surgical interventions and 470,000 outpatients examinations and tests were performed. The detailed clinical activity of the general medicine and the nephrology units in 2002, the role of the scientific direction and that of the Humanitas Foundation have been presented. The work experience, in particular the advantages and disavantages of public versus private environment, represents another important topic of this paper.

To develop and implement a billing process that fully integrates all activities of a pediatric nephrology and transplant program, by facilitating and coordinating data from patients, physicians, hospitals, and third-party billing services to maximize revenues. Financial operations were analyzed via a randomized audit of patient charts that focused on office procedures and revenue collection. Results based on monthly reports documenting revenue received and outstanding, procedures billed, and patient registration accuracy. The combination of improvements in patient registration, chart documentation, new billing sheets with procedure and diagnosis codes, physician in-service education, upgraded charges, and the recredentialing of all practice physicians realized an increase in revenue collections from 18% in 2000 to 89% in 2001. The need to integrate and coordinate information is vital for both billing accuracy and revenue collections. Integration of clinical services and billing procedures has maximized performance, profitability, and accuracy while decreasing administrative time and costs.

2018-06-07

Chronic hyperkalemia is a major complication of chronic kidney disease (CKD) that occurs frequently, heralds poor prognosis, and necessitates careful management by the nephrologist. Current strategies aimed at prevention and treatment of hyperkalemia are still suboptimal, as evidenced by the relatively high prevalence of hyperkalemia in patients under stable nephrology care, and even in the ideal setting of randomized trials where best treatment and monitoring are mandatory. The aim of this review was to identify and discuss a range of unresolved issues related to the management of chronic hyperkalemia in non-dialysis CKD. The following topics of clinical interest were addressed: diagnosis, relationship with main comorbidities of CKD, therapy with inhibitors of the renin-angiotensin-aldosterone system, efficacy of current dietary and pharmacological treatment, and the potential role of the new generation of potassium binders. Opinion-based answers are provided for each of these controversial issues.

Diagnosis of renal diseases is often delayed owing to the scarcity of trained physicians, lack of facilities, and shortage of funds limits effective management, particularly when it comes to the red zone of renal replacement therapy. The Internetis expected to open up a myriad resource of knowledge and applications for academicians, researchers and clinicians alike in all health care professions across the globe. Also, the Internet has grown rapidly over the years and will inevitably expand even more. Evolving technologies offer modern applications for information management, communications with multimedia and virtual reality. Now, these innovative technologies have opened up newer possibilities for nephrologists. As Internet is serving as a backbone for these modern technologies, it is an utmost necessity to use and refine Internet applications for future nephrologists. Increasingly easy access to Internet has dramatically reduced barriers in sharing of information among basic and clinical nephrologists. Considering the growing scope for nephrologists in the use of Internet, it is necessary to understand Internet as a source of information and backbone of modern application. This review illustrates expanding roles of the Internet for the nephrologists and provides ready to use compilation of useful academic, research, clinical resources and is expected to introduce, stimulate and guide nephrologists into the realm of the world wide web. It also investigates how Internet is supporting in growth and development of the field of nephrology and present and future scopes of Internet as a tool for professionals involved in this area as well as information about biological sciences, and it also gives information about societies in various continents working in field of nephrology and the links useful for clinicians and research scientists.

In primary care, patients with chronic kidney disease (CKD) are frequently prescribed excessive doses of antibiotics relative to their kidney function. We examined whether nephrology comanagement is associated with improved prescribing in primary care. In a retrospective propensity score-matched cross-sectional study, we studied the appropriateness of antibiotic prescriptions by primary care physicians to Ontarians ≥66 years of age with CKD Stages 4 and 5 (estimated glomerular filtration rate <30 mL/min/1.73 m2 not receiving dialysis) from 1 April 2003 to 31 March 2014. Comanagement was defined as having at least one outpatient visit with a nephrologist within the year prior to antibiotic prescription date. We compared the rate of appropriately dosed antibiotics in primary care between 3937 patients who were comanaged by a nephrologist and 3937 patients who were not. Only 1184 (30%) of 3937 noncomanaged patients had appropriately dosed antibiotic prescriptions prescribed by a primary care physician. Nephrology comanagement was associated with an increased likelihood that an appropriately dosed prescription was prescribed by a primary care physician; however, the magnitude of the effect was modest [1342/3937 (34%); odds ratio 1.20 (95% confidence interval 1.09-1.32); P < 0.001]. The majority of antibiotics prescribed by primary care physicians are inappropriately dosed in CKD patients, whether or not a nephrologist is comanaging the patient. Nephrologists have an opportunity to increase awareness of appropriate dosing of medications in primary care through the patients they comanage.

The aim of this study was to evaluate the epidemiologic profile of patients and difficulties of patients referred by basic health units (UBS) or other hospitals, outpatient screening of the Division of Nephrology, Hospital São Paulo (UNIFESP) for evaluation and treatment kidney disease. From February to September 2009, has been evaluated 341 patients referred from UBS in São Paulo and other parts of the Country. Of these patients, 26% (86/341) required for new tests to confirm the diagnosis doubtful for referrals, incomplete, or because of the waiting period for the care and exams, which ranged from one week to three years, and part of them did not bring any kind of examination for the evaluation, 12% (45/341) returned for follow-up at the unit location, 13% (46/341) were referred for treatment site closest to their residence, 47% (164/341) for our sub-specialty Clinics of Nephrology (HSP): 24% (82/341) uremia, 8% (27/341) with polycystic kidney disease, 7% (23/341) for hypertension, 4% (16/341) renal Lithiasis and 4% (16/341) nephritis. Our results suggest investments investment in infrastructure in the training of officials of UBS and HSP, reorganization of central references for better management and referral of patients, humanization of care and training of health professionals for outpatient care at UBS in preventive work and basic monitoring of patients, particularly those with diabetes mellitus and hypertension, which can lead to the development of chronic kidney disease (CKD).

Moderator's view: Predictive models: a prelude to precision nephrology.

2017-05-01

Appropriate diagnosis is fundamental in medicine because it sets the basis for the prediction of disease outcome at the single patient level (prognosis) and decisions regarding the most appropriate therapy. However, given the large series of social, clinical and biological factors that determine the likelihood of an individual's future outcome, prognosis only partly depends on diagnosis and aetiology and treatment is not decided solely on the basis of the underlying diagnosis. This issue is crucial in multifactorial diseases like atherosclerosis, where the use of statins has now shifted from 'treating hypercholesterolaemia' to 'treating the risk of adverse cardiovascular events'. Approaches that take due account of prognosis limit the lingering risk of over-diagnosis and maximize the value of prognostic information in the clinical decision process. In the nephrology realm, the application of a well-validated risk equation for kidney failure in Canada led to a 35% reduction in new referrals. Prognostic models based on simple clinical data extractable from clinical files have recently been developed to predict all-cause and cardiovascular mortality in end-stage kidney disease patients. However, research on predictive models in renal diseases remains suboptimal and non-accounting for competing events and measurement errors, and a lack of calibration analyses and external validation are common fallacies in currently available studies. More focus on this blossoming research area is desirable. The nephrology community may now start to apply the best validated risk scores and further test their potential usefulness in chronic kidney disease patients in diverse clinical situations and geographical areas. © The Author 2017.

Identifying predictors of kidney disease progression is critical toward the development of strategies to prevent kidney failure. Clinical notes provide a unique opportunity for big data approaches to identify novel risk factors for disease. We used natural language processing tools to extract concepts from the preceding year's clinical notes among patients newly referred to a tertiary care center's outpatient nephrology clinics and retrospectively evaluated these concepts as predictors for the subsequent development of ESRD using proportional subdistribution hazards (competing risk) regression. The primary outcome was time to ESRD, accounting for a competing risk of death. We identified predictors from univariate and multivariate (adjusting for Tangri linear predictor) models using a 5% threshold for false discovery rate (q value <0.05). We included all patients seen by an adult outpatient nephrologist between January 1, 2004 and June 18, 2014 and excluded patients seen only by transplant nephrology, with preexisting ESRD, with fewer than five clinical notes, with no follow-up, or with no baseline creatinine values. Among the 4013 patients selected in the final study cohort, we identified 960 concepts in the unadjusted analysis and 885 concepts in the adjusted analysis. Novel predictors identified included high-dose ascorbic acid (adjusted hazard ratio, 5.48; 95% confidence interval, 2.80 to 10.70; q<0.001) and fast food (adjusted hazard ratio, 4.34; 95% confidence interval, 2.55 to 7.40; q<0.001). Novel predictors of human disease may be identified using an unbiased approach to analyze text from the electronic health record. Copyright © 2016 by the American Society of Nephrology.

Incidence of dialysis in elderly patients in the Netherlands is low compared to other countries. This study aims to assess the impact of patients' age and comorbidity on the likelihood of referral and acceptance of patients for dialysis and whether this is affected by physician characteristics. A vignette study was performed among 209 primary care physicians, 162 non-nephrology specialists and 20 nephrologists working in the north of the Netherlands. Physicians were offered six vignettes concerning case-reports of patients with end-stage renal disease (ESRD) and varying comorbidities or circumstances and asked about the likelihood of referral/acceptance of the patient in the given circumstances. The likelihood of referral within groups of physicians varied widely, especially within the group of primary care physicians and non-nephrology specialists, but was not affected by characteristics of physicians. The likelihood of referral or acceptance of patients for dialysis depended on the patient's age, and type and severity of comorbidity. In general, primary care physicians and non-nephrology specialists were less likely to refer than nephrologists were to accept. Differences within and between groups of physicians were larger for 80- than for 65-year-old patients, and for patients with less severe shortness of breath and cognitive impairments and more severe diabetes and social impairments. Hardly any differences were found for patients with cancer. Patients' age and comorbidities affect the likelihood of referral. Differences between groups of physicians suggest that there is insufficient agreement on the extent to which these factors should affect the referral/acceptance of patients for dialysis. These findings underline the need for more research into circumstances under which patients might benefit from dialysis. Guidelines should be developed to improve the referral of elderly and less healthy patients.

The incidence of renal replacement therapy varies across countries. However, little is known about the epidemiology of chronic kidney disease (CKD) outcomes. Here we describe progression and mortality risk of patients with CKD but not on renal replacement therapy at outpatient nephrology clinics across Europe using individual data from nine CKD cohorts participating in the European CKD Burden Consortium. A joint model assessed the mean change in estimated glomerular filtration rate (eGFR) and mortality risk simultaneously, thereby accounting for mortality risk when estimating eGFR decline and vice versa, while also correcting for the measurement error in eGFR. Results were adjusted for important risk factors (baseline eGFR, age, sex, albuminuria, primary renal disease, diabetes, hypertension, obesity and smoking) in 27,771 patients from five countries. The adjusted mean annual eGFR decline varied from 0.77 (95% confidence interval 0.45, 1.08) ml/min/1.73m 2 in the Belgium cohort to 2.43 (2.11, 2.75) ml/min/1.73m 2 in the Spanish cohort. As compared to the Italian PIRP cohort, the adjusted mortality hazard ratio varied from 0.22 (0.11, 0.43) in the London LACKABO cohort to 1.30 (1.13, 1.49) in the English CRISIS cohort. These results suggest that the eGFR decline showed minor variation but mortality showed the most variation. Thus, different health care organization systems are potentially associated with differences in outcome of patients with CKD within Europe. These results can be used by policy makers to plan resources on a regional, national and European level. Copyright © 2018 International Society of Nephrology. All rights reserved.

Advances in technology and the ability to interrogate disease pathogenesis using systems biology approaches are exploding. As exemplified by the substantial progress in the personalized diagnosis and treatment of cancer, the application of systems biology to enable precision medicine in other disciplines such as Nephrology is well underway. Infrastructure that permits the integration of clinical data, patient biospecimens and advanced technologies is required for institutions to contribute to, and benefit from research in molecular disease classification and to devise specific and patient-oriented treatments. We describe the establishment of the Biobank for the Molecular Classification of Kidney Disease (BMCKD) at the University of Calgary, Alberta, Canada. The BMCKD consists of a fully equipped wet laboratory, an information technology infrastructure, and a formal operational, ethical and legal framework for banking human biospecimens and storing clinical data. The BMCKD first consolidated a large retrospective cohort of kidney biopsy specimens to create a population-based renal pathology database and tissue inventory of glomerular and other kidney diseases. The BMCKD will continue to prospectively bank all kidney biopsies performed in Southern Alberta. The BMCKD is equipped to perform molecular, clinical and epidemiologic studies in renal pathology. The BMCKD also developed formal biobanking procedures for human specimens such as blood, urine and nucleic acids collected for basic and clinical research studies or for advanced diagnostic technologies in clinical care. The BMCKD is guided by standard operating procedures, an ethics framework and legal agreements with stakeholders that include researchers, data custodians and patients. The design and structure of the BMCKD permits its inclusion in a wide variety of research and clinical activities. The BMCKD is a core multidisciplinary facility that will bridge basic and clinical research and integrate precision medicine into renal pathology and nephrology.

Four decades of kidney transplantation in Cuba.

PubMed

Alfonzo, Jorge P

2013-01-01

This article describes the background, beginnings, development, evolution and outcomes of kidney transplantation in Cuba. Nephrology as a medical specialty in Cuba began in 1962 and was formalized in 1966. Conditions were created to implement renal replacement therapy (including transplants), bring nephrology care to the entire country and train human resources who would assume this responsibility, making Cuba one of the first countries with a comprehensive program for renal patient care. After three unsuccessful cadaveric-donor kidney transplantations in 1968-69, the ensuing history of kidney transplantation can be summarized in the following three stages. 1970-1975: In January 1970, cadaveric-donor kidney transplantation began at the Nephrology Institute. That year, 17 kidney transplantations were performed; four of these patients lived with functional kidneys for 15-25 years; 10-year graft survival was 23.5% (Kaplan-Meier survival curve); HLA typing began in 1974. By December 1975, 170 grafts had been done in three hospitals. 1976-1985: Seven transplantation centers performed 893 grafts during this period. HLA-DR typing was introduced in 1976 and the National Histocompatibility Laboratory Network was founded in 1978. The first related living-donor kidney transplantation was done in 1979. 1986-2011: The National Kidney Transplantation Coordinating Center and the National Kidney Transplantation Program were created in 1986; the first combined kidney-pancreas transplantation was performed the same year. In 1990, cyclosporine and the Cuban monoclonal antibody IOR-T3 were introduced for immunosuppression to prevent rejection, as were other Cuban products (hepatitis B vaccine and recombinant human erythropoietin) for transplant patients. By December 2011, the cumulative number of transplants was 4636 (384 from related living donors). With over 40 years of experience, kidney transplantation is now well established in Cuba; it is free and universally accessible, on the basis of need and appropriateness.

Medication errors may lead to adverse drug events (ADEs), which endangers patient safety and increases healthcare-related costs. The on-ward deployment of clinical pharmacists has been shown to reduce preventable ADEs, and save costs. The purpose of this study was to evaluate the ADEs prevention and cost-saving effects by clinical pharmacist deployment in a nephrology ward.This was a retrospective study, which compared the number of pharmacist interventions 1 year before and after a clinical pharmacist was deployed in a nephrology ward. The clinical pharmacist attended ward rounds, reviewed and revised all medication orders, and gave active recommendations of medication use. For intervention analysis, the numbers and types of the pharmacist's interventions in medication orders and the active recommendations were compared. For cost analysis, both estimated cost saving and avoidance were calculated and compared.The total numbers of pharmacist interventions in medication orders were 824 in 2012 (preintervention), and 1977 in 2013 (postintervention). The numbers of active recommendation were 40 in 2012, and 253 in 2013. The estimated cost savings in 2012 and 2013 were NT$52,072 and NT$144,138, respectively. The estimated cost avoidances of preventable ADEs in 2012 and 2013 were NT$3,383,700 and NT$7,342,200, respectively. The benefit/cost ratio increased from 4.29 to 9.36, and average admission days decreased by 2 days after the on-ward deployment of a clinical pharmacist.The number of pharmacist's interventions increased dramatically after her on-ward deployment. This service could reduce medication errors, preventable ADEs, and costs of both medications and potential ADEs.

Abstract Background Our nephrology fellowship requires specific training in recognition and referral of end-stage renal disease patients likely to benefit from palliative and hospice care. Methods To identify end-of-life (EOL) referral barriers that require greater training emphasis, we performed a cross-sectional, 17-item anonymous online survey (August–October 2015) of 93 nephrologists associated with the program since 1987. Results There was a 61% response rate (57/93 surveys). Ninety-five percent practiced clinical nephrology (54/57). Of these, 51 completed the survey (55% completion rate), and their responses were analyzed. Sixty-four percent were in practice >10 years; 65% resided in the Southern USA. Ninety-two percent felt comfortable discussing EOL care, with no significant difference between those with ≤10 versus  >10 years of practice experience (P = 0.28). Thirty-one percent reported referring patients to EOL care ‘somewhat’ or ‘much less often’ than indicated. The most frequent referral barriers were: time-consuming nature of EOL discussions (27%); difficulty in accurately determining prognosis for <6-month survival (35%); patient (63%) and family (71%) unwillingness; and patient (69%) and family (73%) misconceptions. Fifty-seven percent would refer more patients if dialysis or ultrafiltration could be performed in hospice. Some reported that local palliative care resources (12%) and hospice resources (6%) were insufficient. Conclusions The clinical nephrologists surveyed were comfortable with EOL care discussion and referral. Patient, family, prognostic and system barriers exist, and many reported lower than indicated referral rates. Additional efforts, including, but not limited to, EOL training during fellowship, are needed to overcome familial and structural barriers to facilitate nephrologist referral for EOL care.

Attitudes of Canadian nephrologists, family physicians and patients with kidney failure toward primary care delivery for chronic dialysis patients.

Nephrologists have traditionally assumed responsibility for both nephrological and primary care health problems of their dialysis patients. However, given the increasing limitations of nephrology human resources, there is concern that traditional models may fall short of providing comprehensive care. We studied this issue by distributing three different self-administered surveys to 361 members of the Canadian Society of Nephrology, 325 family physicians, and 163 chronic dialysis patients. The overall response rate was 61.3% for nephrologists, 51% for family physicians, and 90% for patients. More than 50% of Canadian nephrologists are spending approximately one-third of their time in primary care delivery. The majority of these nephrologists and family physicians agree that nephrologists should not be solely responsible for the primary care of patients on dialysis. Yet, both groups of physicians have concerns that family physicians do not have the knowledge/training and time to care for this complicated group of patients. The patients themselves have more confidence in the primary care that is delivered by their family physicians than by their nephrologists. Unfortunately, there is little communication between the two physician groups either between themselves or with their patients about the services that should be provided by their nephrologist or their family physician. Nephrologists and family physicians agree that more primary care for dialysis patients should be provided by family physicians. However, the lack of communication between physicians and patients may result in either a duplication or omission of services that are required by this patient population. Dialysis delivery systems in Canada must evolve to ensure that comprehensive chronic dialysis and primary care is provided to these patients through cooperation and communication with primary care physicians.

Previous reports showed an increased early mortality after chronic dialysis initiation among the end-stage renal disease (ESRD) population. We hypothesized that ESRD patients in the Military Health System (MHS) would have greater access to pre-ESRD care and hence better survival rates during this early high-risk period. In this retrospective cohort study, using the US Renal Data System database, we identified 1,256,640 patients initiated on chronic dialysis from January 2, 2004 through December 31, 2014, from which a bootstrap sample of 3,984 non-MHS incident dialysis patients were compared with 996 MHS patients. We assessed care by a nephrologist and dietitian, erythropoietin administration, and vascular access use at dialysis initiation as well as all-cause mortality as outcome variables. MHS patients were significantly more likely to have had pre-ESRD nephrology care (adjusted OR [aOR] 2.9; 95% CI 2.3-3.7) and arteriovenous fistula used at dialysis initiation (aOR 2.2; 95% CI 1.7-2.7). Crude mortality rates peaked between the 4th and the 8th week for both cohorts but were reduced among MHS patients. The baseline adjusted Cox model showed significantly lower death rates among MHS vs. non-MHS patients at 6, 9, and 12 months. This survival advantage among MHS patients was attenuated after further adjustment for pre-ESRD nephrology care and dialysis vascular access. MHS patients had improved survival within the first 12 months compared to the general ESRD population, which may be explained in part by differences in pre-ESRD nephrology care and vascular access types. © 2017 S.

The education level of women has increased significantly in recent decades. However, although there is a continued positive trend overall, women remain underrepresented (or misrepresented?) in the main fields of science. In Europe the proportion of women in scientific research is growing faster than that of men, but women are more likely than men to choose education, arts and humanities, health and welfare. Moreover, of the total number of women graduating in all faculties (55%), the percentage of women graduating in medicine is 65%-68%, in Europe as in the United States. As far as nephrology is concerned, unpublished data from the Italian Society of Nephrology indicate that female nephrologists make up almost 30% of the total number in the age group between 40 and 55, and this proportion is even higher in the age group younger than 40 years. In comparison with the past, there are some hints that things are going to change, but the path is still a difficult one, much effort is needed and there is a long way ahead.

Quality Measures for Dialysis: Time for a Balanced Scorecard.

PubMed

Kliger, Alan S

2016-02-05

Recent federal legislation establishes a merit-based incentive payment system for physicians, with a scorecard for each professional. The Centers for Medicare and Medicaid Services evaluate quality of care with clinical performance measures and have used these metrics for public reporting and payment to dialysis facilities. Similar metrics may be used for the future merit-based incentive payment system. In nephrology, most clinical performance measures measure processes and intermediate outcomes of care. These metrics were developed from population studies of best practice and do not identify opportunities for individualizing care on the basis of patient characteristics and individual goals of treatment. The In-Center Hemodialysis (ICH) Consumer Assessment of Healthcare Providers and Systems (CAHPS) survey examines patients' perception of care and has entered the arena to evaluate quality of care. A balanced scorecard of quality performance should include three elements: population-based best clinical practice, patient perceptions, and individually crafted patient goals of care.

Pain Management in CKD: A Guide for Nephrology Providers.

PubMed

Koncicki, Holly M; Unruh, Mark; Schell, Jane O

2017-03-01

Although pain is one of the most commonly experienced symptoms by patients with chronic kidney disease, it is under-recognized, the severity is underestimated, and the treatment is inadequate. Pain management is one of the general primary palliative care competencies for medical providers. This review provides nephrology providers with basic skills for pain management. These skills include recognition of types of pain (nociceptive and neuropathic) syndromes and appropriate history-taking skills. Through this history, providers can identify clinical circumstances in which specialist referral is beneficial, including those who are at high risk for addiction, at risk for adverse effects to medications, and those with complicated care needs such as patients with a limited prognosis. Management of pain begins with the development of a shared treatment plan, identification of appropriate medications, and continual follow-up and assessment of efficacy and adverse effects. Through adequate pain management, providers can positively affect the health of individual patients and the performance of health care systems. Copyright © 2016 National Kidney Foundation, Inc.

The complete digitalization of the health system is an objective that Italy, from 2014, is pursuing with great difficulty, spurred by the many European initiatives dedicated to it. Despite the social and cultural background seems to be clearly ready for an application of the renewal strategies, e-Health and m-Health are struggling to get off the ground throughout the territory. The main difficulties are find at local level and don't spare any medical discipline, nephrology included. The characteristics of the official websites belonging to the local health centers demonstrate it. Today, these institutions are still sparsely present on Social Media or in the Italian Smart Mobile Technology landscape. The article illustrates the main features of the phenomenon and calls for reflection on the necessity to accelerate the digital innovation of the communication with patients. This is a possible strategy for reducing chronicity through prevention, and, potentially, for decreasing health costs. Copyright by Società Italiana di Nefrologia SIN, Rome, Italy.

Dried blood spot (DBS) sampling for the purpose of therapeutic drug monitoring can be an attractive alternative for conventional blood sampling, especially in children. This study aimed to compare all costs involved in conventional sampling versus DBS home sampling in two pediatric populations: renal transplant patients and hemato-oncology patients. Total costs were computed from a societal perspective by adding up healthcare cost, patient related costs and costs related to loss of productivity of the caregiver. Switching to DBS home sampling was associated with a cost reduction of 43% for hemato-oncology patients (€277 to €158) and 61% for nephrology patients (€259 to €102) from a societal perspective (total costs) per blood draw. From a healthcare perspective, costs reduced with 7% for hemato-oncology patients and with 21% for nephrology patients. Total savings depend on the number of hospital visits that can be avoided by using home sampling instead of conventional sampling. PMID:27941974

Clinical audit, a valuable tool to improve quality of care: General methodology and applications in nephrology.

PubMed

Esposito, Pasquale; Dal Canton, Antonio

2014-11-06

Evaluation and improvement of quality of care provided to the patients are of crucial importance in the daily clinical practice and in the health policy planning and financing. Different tools have been developed, including incident analysis, health technology assessment and clinical audit. The clinical audit consist of measuring a clinical outcome or a process, against well-defined standards set on the principles of evidence-based medicine in order to identify the changes needed to improve the quality of care. In particular, patients suffering from chronic renal diseases, present many problems that have been set as topics for clinical audit projects, such as hypertension, anaemia and mineral metabolism management. Although the results of these studies have been encouraging, demonstrating the effectiveness of audit, overall the present evidence is not clearly in favour of clinical audit. These findings call attention to the need to further studies to validate this methodology in different operating scenarios. This review examines the principle of clinical audit, focusing on experiences performed in nephrology settings.

2014-11-01

This article describes an ethnographic study focused on exploring leaders of team learning in well-established nephrology teams in an academic healthcare organization in Canada. Employing situational theory of leadership, the article provides details on how well established team members advance as "learning leaders". Data were gathered by ethnographic methods over a 9-month period with the members of two nephrology teams. These learning to care for the sick teams involved over 30 regulated health professionals, such as physicians, nurses, social workers, pharmacists, dietitians and other healthcare practitioners, staff, students and trainees, all of whom were collectively managing obstacles and coordinating efforts. Analysis involved an inductive thematic analysis of observations, reflections, and interview transcripts. The study indicated how well established members progress as team-learning leaders, and how they adapt to an interprofessional culture through the activities they employ to enable day-to-day learning. The article uses situational theory of leadership to generate a detailed illumination of the nature of leaders' interactions within an interprofessional context.

The Brazilian Multicenter Nephropathic Study Group, founded in 1999, is currently composed of 16 pediatric nephrology units, which are coordinated by the Pediatric Nephrology Unit of Instituto da Criança--HCFMUSP. This Study Group intends to better know our patients, their special characteristics and facilitates the treatment. To present an update on the demographics of the ongoing study participants with interest on renal function status, response to therapy, and extra-renal complications. Patient recruitment to the study is based on informed consent and has been supported by the Brazilian Society of Nephrology, by the creation of an electronic homepage and by the participation in medical meetings and publications in medical periodicals. Our study protocol involves the initial and follow-up questionnaire, the measurement of intraleukocyte cystine content, initiation and follow-up therapy with cysteamine, and clinical patient follow-up based on a protocol of subsidiary exams. We identified 102 patients (42 females) with nephropathic cystinosis in Brazil since 1999. Forty-six children are followed at the Instituto da Criança/SP, 15 at the Hospital Pequeno Príncipe/PR, 12 at the UNICAMP/SP, 10 at the Unidade de Transplante Renal - HCFMUSP/SP and 3 at the Santa Casa/SP; the remaining patients are followed at the Instituto da Criança and at their respective doctors' offices in different nephrology services in Brazil. Of these patients, 23/102 (22.5%) have normal renal function, 19/102 (18.6%) are in chronic renal failure with conservative treatment, 26/102 are on dialysis (18 on peritoneal dialysis and 8 on hemodialysis), and 34/102 received a renal transplant. The extra-renal involvement diagnosed was: hypothyroidism in 63 patients, diabetes mellitus in 8 patients, muscular involvement in 7 patients, a compromised central nervous system in 5 patients, hepatic complications in 5 patients, and deglutition dysfunction in 2 patients. During this period, 10/102 patients died. Cysteamine has been used by 81/102 patients (20 children started the therapy under 2 years of age). Growth parameters were improved by cysteamine, mainly in the youngest patients. We used recombinant growth hormone in 15 patients with persistent low growth velocity and stature z score under 2.5%. We could also observe a delay in appearance of extra-renal complications in patients receiving cysteamine. Our study demonstrates the importance of a multi-center study for recruitment, diagnosis and management of rare diseases. This study promotes access to the adequate treatment with profound impact on the quality of life. Copyright 2009 S. Karger AG, Basel.

Six-year single-center survey on AKI requiring renal replacement therapy: epidemiology and health care organization aspects.

Evidence regarding hospital-based acute kidney injury (AKI) reveals a continuous increase in incidence over the years, at least in intensive care units (ICU). Fewer reports are available for non critically-ill patients admitted to general or specialist wards other than ICU (non-ICU). The consequence of greater incidence is an increase in therapies such as dialysis; but how the health care organization deals with this problem is not clearly known. Here we quantified the incidence of dialysis-requiring AKI (AKI-D) among patients admitted to a University Hospital which serves a population of 354,000 inhabitants. Between 2007 and 2012, the incidence of AKI-D increased from 209 to 410 per million population (pmp)/year; age of patients and cardiovascular comorbid pathologies also increased. AKI-D was more frequent in non-ICU and 32% of patients were admitted to ICU. Considering the site of treatment of non-ICU patients, in 2007 the ratio of patients admitted to non-ICU wards apart from Nephrology to those admitted to Nephrology was 1:1, but in 2012 the ratio increased to 2.4:1 (p < 0.05). The complexity of acute disease, measured with the New Simplified Acute Physiology Score (SAPS II), did not reveal differences over the years. The number of dialysis treatments/year increased by 82%, and the total hours/year increased by 86%. Low-efficiency daily dialysis was performed in 52.4% of patients admitted to ICU, but dialysis sessions longer than 8 h were performed in only 40% of cases. Overall, 6-year mortality was 48.8%, without significant differences over the years. Mortality in ICU was 65.6%, and in non-ICU 41.2% (p < 0.001). Dialysis treatments needed to be continued after hospital discharge in 21% of patients. We conclude that dialysis-requiring AKI is becoming more common, and that two-thirds of patients are admitted as non-ICU: in these patients, during the last year of the study, the treatment site was more frequently in non-ICUs other than Nephrology. Over the 6-year period, the local healthcare organization had to dispense 80% more dialysis treatments/year in terms of total number and hours of treatment. One-fifth of surviving patients needed to continue dialysis after hospital discharge. Our data highlight the public health importance of AKI and the need for adequate resources for Nephrology.

Stem cells in nephrology: present status and future.

PubMed

Watorek, Ewa; Klinger, Marian

2006-01-01

Stem cell biology is currently developing rapidly because of the potential therapeutic utility of stem cells. The ability to acquire any desired phenotype raises hope for regenerative therapies. Manipulation of these cells is a potentially valuable tool; however, the mechanisms of stem cell differentiation and plasticity are currently beyond our control. In the field of nephrology, the presence of adult kidney stem cells has been debated. Renal adult stem cells may be descendants of some early kidney progenitors, or may be derived from bone marrow. Evidence of a hematopoietic stem-cell contribution to renal repair encourages the possibility of bone marrow or stem cell transplantation as a means of treating autoimmune glomerulopathies. The transplantation of fetal kidney tissue containing renal progenitors, which then develop into functional nephrons, is a step towards renal regeneration. According to recent reports, the development of functional nephrons from human mesenchymal stem cells in rodent whole-embryo culture is possible. Establishing in vitro self organs from autologous stem cells would be a promising therapeutic solution in light of the shortage of allogenic organs and the unresolved problem of chronic allograft rejection.

Medical educators have called for new teaching methods and materials that supplement the traditional lecture format, and education in a range of health professions, including medicine, nursing, and pharmacy, is using a game-based approach to teach learners. Here, we describe a novel teaching tool in a case-based debate using the game format. Two teams of first- and second-year nephrology fellows participated in a PowerPoint game-based debate about which tests to order to diagnose transplant-related case. Our pilot study assessed the participant acceptance of case-based debate sessions and rewards system, and participant perceptions of using this approach to teach fellows and residents the importance of each test ordered and its cost-effectiveness in medicine. Each test ordered requires an explanation and has a point value attached to it (based on relevance and cost of positive and negative test results). The team that comes up with the diagnosis with most points wins the game. A faculty member leads a short concluding discussion. Subjective evaluations found these case-based debates to be highly entertaining and thought-provoking and to enhance self-directed learning.

Nephrologists between power and vulnerability in times of technology.

PubMed

Obregón, José Miguel Viscarra; Anjos, Marcio Fabri Dos

2018-05-03

The doctor-patient relationship is often discussed from the perspective of patient vulnerability. Little attention is given to the vulnerability of nephrologists in their professional practice, a reality often affected by profound cultural transformation arising from technological development. Nephrology is based on research and procedure instrumentalization, both permeated with technology. In addition, the relationship between nephrologists and institutions is governed by market rules. Recent data showed a shortage of new nephrologists and the need to improve the technical training of new professionals, foster the establishment of interventional nephrology, and attract more graduating physicians to this medical specialty. Bioethics offers a different perspective on the issue, since it takes the subjective concerns of medical doctors and the social environments they participate in into consideration in order to enhance their ethical autonomy. These ideas may be discussed as part of undergraduate or specialization programs, thus reinforcing the acknowledgement of vulnerability as a condition and of the relevance of adopting a reflective attitude toward the events of everyday life that interact with the morality of nephrologists, so that risks are adequately faced having bioethical parameters as a reference.

2014-09-01

There recently has been a paradigm shift in health care policies and research toward greater patient centeredness. A core tenet of patient-centered care is that patients' needs, values, and preferences are respected in clinical decision making. Qualitative research methods are designed to generate insights about patients' priorities, values, and beliefs. However, in the past 5 years (2008-2013), only 23 (0.4%) of the 6,043 original articles published in the top 5 nephrology journals (assessed by impact factor) were qualitative studies. Given this observation, it seems important to promote awareness and better understanding within the nephrology community about qualitative research and how the findings can contribute to improving the quality and outcomes of care for patients with chronic kidney disease. This article outlines examples of how qualitative research can generate insight into the values and preferences of patients with chronic kidney disease, provides an overview of qualitative health research methods, and discusses practical applications for research, practice, and policy.

Year in review: Critical Care 2004 – nephrology

2005-01-01

We summarize all original research in the field of critical care nephrology published in 2004 or accepted for publication in Critical Care and, when considered relevant or directly linked to this research, in other journals. Articles were grouped into four categories to facilitate a rapid overview. First, regarding the definition of acute renal failure (ARF), the RIFLE criteria (risk, injury, failure, loss, ESKD [end-stage kidney disease]) for diagnosis of ARF were defined by the Acute Dialysis Quality Initiative workgroup and applied in clinical practice by some authors. The second category is acid–base disorders in ARF; the Stewart–Figge quantitative approach to acidosis in critically ill patients has been utilized by two groups of researchers, with similar results but different conclusions. In the third category – blood markers during ARF – cystatin C as an early marker of ARF and procalcitonin as a sepsis marker during continuous venovenous haemofiltration were examined. Finally, in the extracorporeal treatment of ARF, the ability of two types of high cutoff haemofilters to influence blood levels of middle- and high-molecular-weight toxins showed promise.

2018-05-01

The genesis of whole exome sequencing as a powerful tool for detailing the protein coding sequence of the human genome was conceptualized based on the availability of next-generation sequencing technology and knowledge of the human reference genome. The field of pediatric nephrology enriched with molecularly unsolved phenotypes is allowing the clinical and research application of whole exome sequencing to enable novel gene discovery and provide amendment of phenotypic misclassification. Recent studies in the field have informed us that newer high-throughput sequencing techniques are likely to be of high yield when applied in conjunction with conventional genomic approaches such as linkage analysis and other strategies used to focus subsequent analysis. They have also emphasized the need for the validation of novel genetic findings in large collaborative cohorts and the production of robust corroborative biological data. The well-structured application of comprehensive genomic testing in clinical and research arenas will hopefully continue to advance patient care and precision medicine, but does call for attention to be paid to its integrated challenges.

Urea removal has become a key measure of the intensity of dialysis treatment for kidney failure. Small solute removal, exemplified by Kt/V urea, 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. On behalf of the American Society of Nephrology Dialysis Advisory Group, we propose the need to ascertain the validity and utility of a multidimensional measure that moves beyond small solute kinetics alone to quantify optimal dialysis derived from both patient-reported and comprehensive clinical and dialysis-related measures.

New Organ Allocation System for Combined Liver-Kidney Transplants and the Availability of Kidneys for Transplant to Patients with Stage 4-5 CKD.

Asch, William S; Bia, Margaret J

2017-05-08

A new proposal has been created for establishing medical criteria for organ allocation in recipients receiving simultaneous liver-kidney transplants. In this article, we describe the new policy, elaborate on the points of greatest controversy, and offer a perspective on the policy going forward. Although we applaud the fact that simultaneous liver-kidney transplant activity will now be monitored and appreciate the creation of medical criteria for allocation in simultaneous liver-kidney transplants, we argue that some of the criteria proposed, especially those for allocating a kidney to a liver recipient with AKI, are too liberal. We call on the nephrology community to follow the consequences of this new policy and push for a re-examination of the longstanding policy of allocating kidneys to multiorgan transplant recipients before all other candidates. The charge to protect our system of equitable organ allocation is very challenging, but it is a challenge that we must embrace. Copyright © 2017 by the American Society of Nephrology.

Zirconium: biomedical and nephrological applications.

Lee, David B N; Roberts, Martin; Bluchel, Christian G; Odell, Ross A

2010-01-01

Recent years have witnessed a rapid increase in the use of zirconium (Zr)-containing compounds in artificial internal organs. Examples include dental implants and other restorative practices, total knee and hip replacement, and middle-ear ossicular chain reconstruction. In nephrological practice, Zr-containing sorbents have been used in hemofiltration, hemodialysis, peritoneal dialysis, and in the design and construction of wearable artificial kidneys. Zr compounds continue to be widely and extensively used in deodorant and antiperspirant preparations. In the public health arena, Zr compounds have been studied or used in controlling phosphorus pollution and in the reclamation of poison and bacteria-contaminated water. Experimental and clinical studies support the general consensus that Zr compounds are biocompatible and exhibit low toxicity. Reports on possible Zr-associated adverse reactions are rare and, in general, have not rigorously established a cause-and-effect relationship. Although publications on the use of Zr compounds have continued to increase in recent years, reports on Zr toxicity have virtually disappeared from the medical literature. Nevertheless, familiarity with, and continued vigilant monitoring of, the use of these compounds are warranted. This article provides an updated review on the biomedical use of Zr compounds.

Urinalysis and proteinuria testing represent fundamental tests for the clinician, even though they too often lack standardization. Through the Italian Society of Nephrology Mailing List we sent a questionnaire to 282 centers, in order to assess the state of the art in Italy in the year 2006. 82% of the questionnaires were completed (nephrology laboratories: 64%, general laboratories: 36%). The questionnaire dealt with the main steps of preparation, analysis and report of urinalysis, and proteinuria / microalbuminuria measurement. 85% of the centers use first morning urine, and 7% second morning urine; only 57% of the centers supply with written instructions, 189 laboratories (82%) have only one bright field microscope, rate and time of centrifugation are very varied among centers, different units of measurement are used in reports. Few laboratories measure routinely the proteinuria / creatininuria ratio, there is no agreement on the urine sample type for microalbuminuria assay, total urinary proteins are measured through different methods. 92% of the centers is endowed with an internal quality control system, but only 47% participate in an external quality control program. These data confirm the lack of standardization for urine analysis methods and procedures.

[Plasma exchange in nephrology: Indications and technique].

2017-02-01

Plasma exchange is a non-selective apheresis technique that can be performed by filtration or centrifugation allowing rapid purification of high molecular weight pathogens. An immunosuppressive treatment is generally associated to reduce the rebound effect of the purified substance. Substitution solutes such as human albumin and macromolecules are needed to compensate for plasma extraction. Compensation by viro-attenuated plasma is reserved solely for the treatment of thrombotic microangiopathies or when there is a risk of bleeding, because this product is very allergenic and expensive. The treatment goal for a plasma exchange session should be between one and one and one-half times the patient's plasma volume estimated at 40 mL/kg body weight. The anticoagulation is best ensured by the citrate. Complications of plasma exchange are quite rare according to the French hemapheresis registry. The level of evidence of efficacy of plasma exchange in nephrology varies from one pathology to another. Main indications of plasma exchange in nephrology are Goodpasture syndrome, antineutrophil cytoplasmic antibody vasculitis when plasma creatinine is greater than 500 μmol/L, and thrombotic microangiopathies. During renal transplantation, plasma exchange may be proposed in the context of human leukocyte antigen (HLA) desensitization protocols or ABO-incompatible graft. After renal transplantation, plasma exchange is indicated as part of the treatment of acute humoral rejection or recurrent focal segmental glomerulosclerosis on the graft. Plasma exchanges are also proposed in the management of cryoglobulinemia or polyarteritis nodosa. Hemodialysis with membranes of very high permeability tends to replace plasma exchange for myeloma nephropathy. The benefit from plasma exchange has not been formally demonstrated for the treatment of severe lupus or antiphospholipid antibody syndrome. There is no indication of plasma exchange in the treatment of scleroderma or nephrogenic systemic fibrosis. More selective apheresis techniques such as immunoadsorption are currently proposed to replace plasma exchange. Copyright © 2016. Published by Elsevier SAS.

Vascular access creation before hemodialysis initiation and use: a population-based cohort study.

In Canada, approximately 17% of patients use an arteriovenous access (fistula or arteriovenous graft) at commencement of hemodialysis, despite guideline recommendations promoting its timely creation and use. It is unclear if this low pattern of use is attributable to the lack of surgical creation or a high nonuse rate. Using large health care databases in Ontario, Canada, a population-based cohort of adult patients (≥18 years old) who initiated hemodialysis as their first form of RRT between 2001 and 2010 was studied. The aims were to (1) estimate the proportion of patients who had an arteriovenous access created before starting hemodialysis and the proportion who successfully used it at hemodialysis start, (2) test for secular trends in arteriovenous access creation, and (3) estimate the effect of late nephrology referral and patient characteristics on arteriovenous access creation. There were 17,183 patients on incident hemodialysis. The mean age was 65.8 years, 60% were men, and 40% were referred late to a nephrologist; 27% of patients (4556 of 17,183) had one or more arteriovenous accesses created, and the median time between arteriovenous access creation and hemodialysis start was 184 days. When late referrals were excluded, 39% of patients (4007 of 10,291) had one or more arteriovenous accesses created, and 27% of patients (2724 of 10,291) used the arteriovenous access. Since 2001, there has been a decline in arteriovenous access creation before hemodialysis initiation. Women, higher numbers of comorbidities, and rural residence were consistently associated with lower rates of arteriovenous access creation. These results persisted even after removing patients with <6 months nephrology care or who had AKI 6 months before starting hemodialysis. In Canada, arteriovenous access creation before hemodialysis initiation is low, even among patients followed by a nephrologist. Better understanding of the barriers and influencers of arteriovenous access creation is needed to inform both clinical care and guidelines. Copyright © 2015 by the American Society of Nephrology.

Systems Thinking and Leadership: How Nephrologists Can Transform Dialysis Safety to Prevent Infections.

PubMed

Wong, Leslie P

2018-04-06

Infections are the second leading cause of death for patients with ESKD. Despite multiple efforts, nephrologists have been unable to prevent infections in dialysis facilities. The American Society of Nephrology and the Centers for Disease Control and Prevention have partnered to create Nephrologists Transforming Dialysis Safety to promote nephrologist leadership and engagement in efforts to "Target Zero" preventable dialysis infections. Because traditional approaches to infection control and prevention in dialysis facilities have had limited success, Nephrologists Transforming Dialysis Safety is reconceptualizing the problem in the context of the complexity of health care systems and organizational behavior. By identifying different parts of a problem and attempting to understand how these parts interact and produce a result, systems thinking has effectively tackled difficult problems in dynamic settings. The dialysis facility is composed of different physical and human elements that are interconnected and affect not only behavior but also, the existence of a culture of safety that promotes infection prevention. Because dialysis infections result from a complex system of interactions between caregivers, patients, dialysis organizations, and the environment, attempts to address infections by focusing on one element in isolation often fail. Creating a sense of urgency and commitment to eradicating dialysis infections requires leadership and motivational skills. These skills are not taught in the standard nephrology or medical director curriculum. Effective leadership by medical directors and engagement in infection prevention by nephrologists are required to create a culture of safety. It is imperative that nephrologists commit to leadership training and embrace their potential as change agents to prevent infections in dialysis facilities. This paper explores the systemic factors contributing to the ongoing dialysis infection crisis in the United States and the role of nephrologists in instilling a culture of safety in which infections can be anticipated and prevented.

During the four-month internal medicine clerkship in their final year, undergraduate medical students are closely involved in patient care. Little is known about what constitutes their typical learning experiences with respect to patient diversity within the different subspecialties of internal medicine and during on call hours. 25 final year medical students (16 female, 9 male) on their internal medicine clerkship participated in this observational single-center study. To detail the patient diversity encountered by medical students at a university hospital during their 16-week internal medicine clerkship, all participants self-reported their patient contacts in the different subspecialties and during on call hours on patient encounter cards. Patients' chief complaint, suspected main diagnosis, planned diagnostic investigations, and therapy in seven different internal medicine subspecialties and the on call medicine service were documented. 496 PECs were analysed in total. The greatest diversity of chief complaints (CC) and suspected main diagnoses (SMD) was observed in patients encountered on call, with the combined frequencies of the three most common CCs or SMDs accounting for only 23% and 25%, respectively. Combined, the three most commonly encountered CC/SMD accounted for high percentages (82%/63%), i.e. less diversity, in oncology and low percentages (37%/32%), i.e. high diversity, in nephrology. The percentage of all diagnostic investigations and therapies that were classified as "basic" differed between the subspecialties from 82%/94% (on call) to 37%/50% (pulmonology/oncology). The only subspecialty with no significant difference compared with on call was nephrology for diagnostic investigations. With respect to therapy, nephrology and infectious diseases showed no significant differences compared with on call. Internal medicine clerkships at a university hospital provide students with a very limited patient diversity in most internal medicine subspecialties. Shadowing the on call resident or shorter rotations could provide a more extended patient diversity.

Acute kidney injury burden in different clinical units: Data from nationwide survey in China

Yu, Shengqiang; Yang, Li; Mei, Changlin

2017-01-01

Background The inpatient morbidity and mortality of acute kidney injury (AKI) vary considerably in different clinical units, yet studies to compare the difference remain limited. Methods We compared the clinical characteristics of AKI in Intensive Care Unit (ICU), medical and surgical departments by using the data derived from the 2013 nationwide cross-sectional survey of AKI in China to capture variations among different clinical departments in recognition, management, and outcomes of AKI. Suspected AKI patients were identified based on changes in serum creatinine during hospitalization, and confirmed by reviewing medical records. Results The detection rate of AKI was the highest in ICU (22.46%), followed by the rates in medical (1.96%) and surgical departments (0.96%). However, the absolute number of cases was the largest in medical departments, which contributed to 50% of the cases. In medical departments, 78% of AKI cases were extensively distributed in cardiac, nephrology, oncology, gastroenterology, pneumology and neurology departments. In contrast, 87% of AKI cases in surgical departments were mainly from urology, general surgery and cardiothoracic departments. The in-time recognition rates were extremely low in all departments except nephrology. Only 10.5~15.0% AKI patients from non-nephrology departments received renal referral. Among all the death cases, 50% and 39% came from ICU and medical departments while only 11% from surgical departments. Older age, higher AKI stage and renal replacement therapy indication were identified as risk factors for high mortality in all departments. Delayed recognition and no renal referral were significantly associated with increased mortality in medical and ICU patients. Conclusions These findings suggest that ICU and medical departments are major affected departments in China with a large number of AKI cases and subsequent high mortality. The reality is more alarming considering the low awareness of AKI and the paucity of effective interventions in the high-risk patients in these departments. PMID:28152018

2004-01-01

Nonadherence is common in the U.S. dialysis population. No single strategy has been definitely proven to yield universal and/or lasting improvements in adherence. However, using a patient-centered approach, including the removal of barriers to adherence, ongoing education, and cognitive behavioral strategies, may generate increased opportunities for patients and the nephrology staff to improve both adherence and outcomes.

2015-03-01

There is considerable concern within the nephrology community about recent federal budget cuts and the decreasing availability of funds for research. This is especially difficult for junior investigators who are about to start a career as physician-scientists. Accordingly, it is imperative that resources other than federal funds be made available to these individuals during this most delicate yet crucial transition period. This commentary aims to provide an overview of nonfederal funding resources, focusing on the Norman S. Coplon Extramural Grant Program. This program emphasizes support of investigators at the most fragile period in their development of an academic career; it has provided >$11 million of research funds to more than 80 individuals since 2000. The outcome has been stellar, with more than 130 publications originating from these projects and >90% of awardees staying in academia. We hope these accomplishments will encourage similar activities by other entities and scientific programs in addition to ones that are ongoing. Ultimately, these collective efforts will inspire young researchers to use their knowledge, passion, and dedication to advance research into kidney diseases.

Health information technology: help or hindrance?

PubMed

Ketchersid, Terry

2014-07-01

The practice of medicine in general and nephrology in particular grows increasingly complex with each passing year. In parallel with this trend, the purchasers of health care are slowly shifting the reimbursement paradigm from one based on rewarding transactions, or work performed, to one that rewards value delivered. Within this context, the health-care value equation is broadly defined as quality divided by costs. Health information technology has been widely recognized as 1 of the foundations for delivering better care at lower costs. As the largest purchaser of health care in the world, the Centers for Medicare and Medicaid Services has deployed a series of interrelated programs designed to spur the adoption and utilization of health information technology. This review examines our known collective experience in the practice of nephrology to date with several of these programs and attempts to answer the following question: Is health information technology helping or hindering the delivery of value to the nation's health-care system? Through this review, it was concluded overall that the effect of health information technology appears positive; however, it cannot be objectively determined because of the infancy of its utilization in the practice of medicine.

We describe the course of pregnancy in a 27-year-old woman with homozygous autosomal recessive Alport syndrome. Genetic analysis revealed a homozygous COL4A4 mutation in exon 36 (c.3307G > A) with p.G1102R inherited from her parents (who were parallel cousins) 1 year before conception. Before pregnancy, the patient's renal function and blood pressure were normal, and her urinary protein excretion was below 2 g/day. The pregnancy course was uneventful in the first and second trimesters. She was detected to have nephrotic-range proteinuria during the third trimester, but was observed closely on an outpatient basis without any medications, as her general condition was good, her renal function and blood pressure remained stable, and the fetal well-being was maintained. At 39(+0) weeks of pregnancy, she vaginally gave birth to an appropriate-birthweight infant and her urinary protein excretion returned to pre-pregnancy level. This is the first report of pregnancy in a patient with autosomal recessive Alport syndrome with good obstetric and nephrological outcomes in the absence of any treatment or hospitalization. © 2015 Japan Society of Obstetrics and Gynecology.

Legal Issues for the Medical Director.

PubMed

Trulove, William G

2015-09-04

The nephrologist serving as medical director of a dialysis clinic must understand that the role of director is not simply an extension of being a good nephrologist. The two roles-nephrology practice and the leadership of a dialysis clinic-may be filled by a single person. However, each role contains unique tasks, requiring specific skill sets, and each role comes with inherent, associated legal risks. The medical director assumes a new level of responsibility and accountability defined by contractual obligations to the dialysis provider and by state and federal regulations. Hence, a medical director is accountable not only for providing standard-of-care treatment to his or her private practice patients dialyzed at the clinic but also for maintaining the safety of the dialysis clinic patient population and staff. Accordingly, a nephrologist serving in the role of medical director faces distinct legal risks beyond typical professional liability concerns. The medical director must also be mindful of regulatory compliance, unique avenues to licensure board complaints, and implications of careless communication habits. A thoughtful and prepared medical director can mitigate these risk exposures by understanding the sources of these challenges: contractual obligations, pertinent regulatory responsibilities, and the modern electronic communications environment.

The 60th anniversary of Israel coincides with the advent of the first hemodialysis in the Middle East. It was performed by Dr. Kurt Steinitz--a Jewish immigrant from Breslau, then in Germany. After spending 9 years at the Istanbul Faculty of Medicine as a clinical biochemist, Steinitz became the director of the chemical laboratory of the Rothschild Hospital in Haifa in 1945. During the spring of 1948, he completed the construction of a hemodialysis machine according to articles published by Kolff (The Netherlands) and mainly by Alwall (Sweden). Three anuric patients underwent hemodialysis. Only the last patient survived. She was a young woman who became anuric after an operation for an extrauterine pregnancy and an incompatible blood transfusion. During the 28th and the 30th September 1948, she had three successful hemodialysis sessions and improved promptly. She lived another fifteen fruitful years. Later, Dr Steinitz' interest shifted to other medical fields, thus leaving the stage of hemodialysis to Prof. David Ullman from the Hadassah Hospital in Jerusalem. Ullman established the first nephrology unit with a regular dialysis service, becoming the pioneer of modern nephrology in Israel.

Online CKD education for medical students, residents, and fellows: training in a new era.

CKD and its complications are associated with substantial morbidity and mortality. Studies have highlighted significant deficiencies in resident knowledge and awareness of CKD and its complications. There is a need to improve CKD education through medical school and residency. There is also a need to provide alternatives to traditional teaching methods to meet the challenges of learning in the context of work-hour restrictions and increasing workload among residents and fellows. Internet-based learning resources offer various educational tools, including websites, kidney blogs, online modules, and smartphone applications, which could potentially and efficiently advance CKD knowledge among medical trainees. In this review, we describe several online resources for CKD education that could be useful for medical students, residents, and fellows. Increased awareness of these tools and their utilization may significantly influence and hopefully improve the recognition and management of patients with CKD. Future studies may help evaluate the effectiveness of these online learning methods and their effect on CKD patient outcomes. In addition, in light of increased concern about nephrology workforce issues, the potential for these online tools to augment interest in nephrology careers should be investigated.

Nephrology, a newly rich speciality, is looking for an illustrious ancestry: what about a famous grandfather?

PubMed

Diamandopoulos, A A; Goudas, P C

2000-01-01

Nephrology is a newborn speciality compared to the other medical specialities. However, the study of the urinary tract's physiology and pathology had begun simultaneously with the birth of medicine. The scientific revolution of the renaissance and enlightenment eras caused an intense contestation of earlier theories and methods as if all knowledge had evolved suddenly from parthenogenesis after the dark (?) medieval years and human intellect suddenly exploded to huge intelligence quotients after the 15th century while before that humans were mentally deprived. Indeed most of the scientific knowledge did evolve impressively during renaissance and enlightenment years but not through parthenogenesis. Some observations, discoveries and inventions of this era were actually reobservations, rediscoveries and reinventions. Such an example is that of the experiments of Sanctorius Santorii of the 16th century AD and of Erasistratus of the 3rd century BC. Sanctorius and Erasistratus carried out an experiment with the same basic principles, similar methodology and proportional results with an almost 2000 years lag phase. With our paper we wish to give credit to earlier researchers of physiological and medical knowledge who, despite the lack of technological support, often concluded in extremely accurate observations.

Can patients with schizophrenia undergo renal transplantation with success?

PubMed

Bouhlel, Saoussen

2014-05-01

We report a case of a 41-year-old man suffering from paranoid schizophrenia. The patient has been consulting in our psychiatric hospital since he was 29 years old. Eight years later, he developed kidney failure and required peritoneal dialysis. After more than two years, the nephrology team indicated a renal transplantation and his brother suggested giving his kidney. There were no obstacles for transplantation in the immune and histological compatibilities; the psychiatric staff decided to check the patient's compliance with medication. The patient was compliant to all his medications and to the salt-free diet after the transplant operation. Few weeks later, he developed steroid-induced diabetes. Through the last two years, he had psychotic exacerbations with major anxiety and fear of losing the transplant. These relapses were managed by increasing doses of antipsychotics without need for hospitalization. At the present time, three years after transplantation, the nephrologists are decreasing the immunosuppressive agents and the steroids. The renal function is optimum and the diabetes is stabilized. This case exemplifies the potential for schizophrenic patients to undergo renal transplantation and to comply with follow-up medical care through a close cooperation between the patient's family, the psychiatric staff and the nephrology team.

20 years since the establishment of the BANTAO association (Balkan Cities Association of Nephrology, Dialysis, Transplantation and Artificial Organs).

The Balkan Cities Association of Nephrology, Dialysis, Transplantation and Artificial Organs (BANTAO) was born in Ohrid on October 9, 1993. The war in former Yugoslavia negatively affected the development of nephrology and also the connections among the nephrologists from the Balkans. However, there was willingness for further mutual collaboration between the nephrologists from the Balkans. The war in Yugoslavia created hate among people, between the newly established countries, and there were problems with the recognition of the names of the new countries, and so, the nephrologists decided to apply the ancient principle of using the names of the cities, instead of the countries, as the founders of the Association. The main goal of BANTAO is to promote scientific and technical cooperation in the fields of renal disease and artificial organs between the regions on the Balkan Peninsula and the world, to give an opportunity for exchange of experience and knowledge among the experts in the area and to engage in collaborative projects in order to demonstrate that cooperation is possible even on the turbulent Balkan Peninsula. The I BANTAO congress was held in Varna from September 22 to 24th, 1995 (President--D. Nenov, Varna). The II congress of BANTAO was held from September 6th to 10th, 1997 in Struga, (President--M. Polenakovic, Skopje). The III BANTAO congress was held in Belgrade from September 18th to 20th, 1998 (President--Lj. Djukanović, Belgrade). The IV congress of BANTAO was held in Izmir from 14th to 16th November 1999 (President--A. Akcicek, Izmir). The V Congress of BANTAO was held in Thessaloniki from September 30th to October 3rd, 2001 (President--P. Stathakis, Athens). The VI Congress of BANTAO was held for the second time in Varna from 6th to 9th October 2003 (President--D. Nenov, Varna). The VII congress of BANTAO was held from September 8th to 11th, 2005 in Ohrid, (President--M. Polenakovic, Skopje). The VIII BANTAO congress was held in Belgrade, 16-19 September 2007 (President--V. Nesic, Belgrade). The IX BANTAO congress was held in Antalya, 18-22 November 2009 (President--A. Basci, Izmir). The X BANTAO congress was held from 13 to 15 October 2011 in Chalkidiki (President--D. Tsakiris, Thessaloniki). The XI BANTAO congress is being held on 26-29 September 2013 in Timisoara (President--A. Schiller, Timisoara). At the VII BANTAO Congress for the first time a CME Course was organized by ERA/EDTA and ISN/COMGAN entitled "Frontiers in Nephrology" with seven distinguished speakers. Very important event in the existence of BANTAO is the appearance of the BANTAO journal in 2003. The BANTAO journal has been published biannually since 2003. In the past 10 years, 20 regular issues; 2 supplements (Antalia and Chalkidiki congresses) have been published. Editors of the journal were as follows: 2003-2005--D. Nenov, Editor; 2005-2009--A. Basci, Editor; 2009--Goce Spasovski, Editor. Until now 332 papers have been published. The BANTAO journal is on EBSCO, DOAJ, SCOPUS. After the First Congress of BANTAO, F. Valderrábano, chairman of the EDTA--ERA Registry, at that time, wrote in Nephrology Dialysis Transplantation (1996) 11:740: "Nephrologists of the Balkan countries meet across political frontiers and war fronts--an example to politicians! a new European Medical Association overcomes Political obstacles." Despite the difficulties imposed by major events, such as devastating wars and catastrophic earthquakes in many countries of the Balkan Peninsula BANTAO has made considerable progress. The BANTAO Congress was established as the major scientific and institutional forum for Balkan nephrologists, with its own journal, indicating our will to communicate, to collaborate, to get to know each other and to share our difficulties. Now, we expect further successful work of BANTAO.

A comprehensive cooperative project for children with renal diseases in Nicaragua.

2010-11-01

In low-income countries renal diseases generally and chronic kidney disease (CKD) in particular represent a wide-spread and often underdiagnosed clinical problem. The aim of the cooperative project between the pediatric nephrology units of Milan, Italy, and Managua, Nicaragua was to improve the diagnosis and treatment of renal diseases and CKD in Nicaraguan children. When the project started, in 2000, there were many constraints in human and material resources in the Children's Hospital in Managua. Since 2001, a specialized Unit of Pediatric Nephrology and Urology has developed, offering free of charge basic clinical assistance to hospitalized children, and training abroad of the whole staff. Shared protocols, renovation of infrastructure and an information technology (IT) program were implemented. In 2003, renal replacement therapy (RRT) for selected children was initiated, along with a network of six department hospitals in 2005 and, in 2007, a CKD prevention program in the most peripheral Health Units, so that 61% of the Nicaraguan pediatric population is now covered by the project. To ensure implementation of the project, applications for funds to Italian private and public institutions were made and a Nicaraguan charity foundation was activated. The Nicaraguan Ministry of Health and the hospital directors were always involved in the plans of the development of the project and accepted the progressive transfer of the costs to the government, throughout the 9-year duration of the project. The IT program, inclusive of a database of children with kidney and other urinary tract (UT) diseases and a web connection between Milan and Managua, was crucial in monitoring the activities and providing epidemiological data, in order to better allocate resources. The clinical activities and the number of children managed in Managua in 2008 are similar to those of pediatric nephrology units worldwide and depict the level of clinical autonomy achieved. The sister-center model of cooperation and the top-down strategy we applied, along with the careful consideration of all the economic, logistic and political issues, were and are the key factors which explain the favorable results of this cooperative project.

The objectives of the symposium were (1) to gain an understanding of the goals of care for CKD patients, (2) to gain an appreciation of different perspectives regarding optimal care for patients with CKD, (3) to examine the components required for optimal care including education strategies, structures, and tools, and (4) to describe a framework and metrics for CKD care which respect patient and system needs. This article summarizes the key concepts discussed at the symposium from a patient and physician perspectives. Key messages include (1) understanding patient values and preferences is important as it provides a framework as to what to prioritize in multidisciplinary CKD clinic and provincial renal program models, (2) barriers to effective communication and education are common in the elderly, and adaptive strategies to limit their influence are critical to improve adherence and facilitate shared decision-making, (3) the use of standardized operating procedures (SOPs) improves efficiency and minimizes practice variability among health care practitioners, and (4) CKD scorecards with standardized system processes are useful in approaching variability as well as measuring and improving patient outcomes. The perspectives provided may not be applicable across centers given the differences in patient populations including age, ethnicity, culture, language, socioeconomic status, education, and multidisciplinary CKD clinic structure and function. Knowledge transmission by collaborative interprovincial and interprofessional networks may play a role in facilitating optimal CKD care. Validation of system and clinic models that improve outcomes is needed prior to disseminating these best practices.

Primary care physicians (PCPs) typically manage early chronic kidney disease (CKD), but recent guidelines recommend nephrology co-management for some patients with stage 3 CKD and all patients with stage 4 CKD. We sought to compare quality of care for co-managed patients to solo managed patients. We conducted a retrospective cross-sectional analysis. Patients included in the study were adults who visited a PCP during 2009 with laboratory evidence of CKD in the preceding two years, defined as two estimated glomerular filtration rates (eGFR) between 15-59 mL/min/1.73 m(2) separated by 90 days. We assessed process measures (serum eGFR test, urine protein/albumin test, angiotensin converting enzyme inhibitor or angiotensin receptor blocker [ACE/ARB] prescription, and several tests monitoring for complications) and intermediate clinical outcomes (mean blood pressure and blood pressure control) and performed subgroup analyses by CKD stage. Of 3118 patients, 11 % were co-managed by a nephrologist. Co-management was associated with younger age (69 vs. 74 years), male gender (46 % vs. 34 %), minority race/ethnicity (black 32 % vs. 22 %; Hispanic 13 % vs. 8 %), hypertension (75 % vs. 66 %), diabetes (42 % vs. 26 %), and more PCP visits (5.0 vs. 3.9; p < 0.001 for all comparisons). After adjustment, co-management was associated with serum eGFR test (98 % vs. 94 %, p = <0.0001), urine protein/albumin test (82 % vs 36 %, p < 0.0001), and ACE/ARB prescription (77 % vs. 69 %, p = 0.03). Co-management was associated with monitoring for anemia and metabolic bone disease, but was not associated with lipid monitoring, differences in mean blood pressure (133/69 mmHg vs. 131/70 mmHg, p > 0.50) or blood pressure control. A subgroup analysis of Stage 4 CKD patients did not show a significant association between co-management and ACE/ARB prescription (80 % vs. 73 %, p = 0.26). For stage 3 and 4 CKD patients, nephrology co-management was associated with increased stage-appropriate monitoring and ACE/ARB prescribing, but not improved blood pressure control.

Simulation-based-mastery-learning (SBML) is an effective method to train nephrology fellows to competently insert temporary, non-tunneled hemodialysis catheters (NTHCs). Previous studies of SBML for NTHC-insertion have been conducted at a local level. Determine if SBML for NTHC-insertion can be effective when provided at a national continuing medical education (CME) meeting. Describe the correlation of demographic factors, prior experience with NTHC-insertion and procedural self-confidence with simulated performance of the procedure. Pre-test - post-test study. 2014 Canadian Society of Nephrology annual meeting. Nephrology fellows, internal medicine residents and medical students. Participants were surveyed regarding demographics, prior NTHC-insertion experience, procedural self-confidence and attitudes regarding the training they received. NTHC-insertion skills were assessed using a 28-item checklist. Participants underwent a pre-test of their NTHC-insertion skills at the internal jugular site using a realistic patient simulator and ultrasound machine. Participants then had a training session that included a didactic presentation and 2 hours of deliberate practice using the simulator. On the following day, trainees completed a post-test of their NTHC-insertion skills. All participants were required to meet or exceed a minimum passing score (MPS) previously set at 79%. Trainees who did not reach the MPS were required to perform more deliberate practice until the MPS was achieved. Twenty-two individuals participated in SBML training. None met or exceeded the MPS at baseline with a median checklist score of 20 (IQR, 7.25 to 21). Seventeen of 22 participants (77%) completed post-testing and improved their scores to a median of 27 (IQR, 26 to 28; p < 0.001). All met or exceeded the MPS on their first attempt. There were no significant correlations between demographics, prior experience or procedural self-confidence with pre-test performance. Small sample-size and self-selection of participants. Costs could limit the long-term feasibility of providing this type of training at a CME conference. Despite most participants reporting having previously inserted NTHCs in clinical practice, none met the MPS at baseline; this suggests their prior training may have been inadequate.

The high-throughput, high-resolution phenotyping enabled by metabolomics has been applied increasingly to a variety of questions in nephrology research. This article provides an overview of current metabolomics methodologies and nomenclature, citing specific considerations in sample preparation, metabolite measurement, and data analysis that investigators should understand when examining the literature or designing a study. Furthermore, we review several notable findings that have emerged in the literature that both highlight some of the limitations of current profiling approaches, as well as outline specific strengths unique to metabolomics. More specifically, we review data on the following: (i) tryptophan metabolites and chronic kidney disease onset, illustrating the interpretation of metabolite data in the context of established biochemical pathways; (ii) trimethylamine-N-oxide and cardiovascular disease in chronic kidney disease, illustrating the integration of exogenous and endogenous inputs to the blood metabolome; and (iii) renal mitochondrial function in diabetic kidney disease and acute kidney injury, illustrating the potential for rapid translation of metabolite data for diagnostic or therapeutic aims. Finally, we review future directions, including the need to better characterize interperson and intraperson variation in the metabolome, pool existing data sets to identify the most robust signals, and capitalize on the discovery potential of emerging nontargeted methods.

Healthcare for patients with advanced chronic kidney disease (ACKD) on conservative treatment very often poses healthcare problems that are difficult to solve. At the end of 2011, we began a program based on the care and monitoring of these patients by Primary Care Teams. ACKD patients who opted for conservative treatment were offered the chance to be cared for mainly at home by the Primary Care doctor and nurse, under the coordination of the Palliative Care Unit and the Nephrology Department. During 2012, 2013, and 2014, 76 patients received treatment in this program (mean age: 81 years; mean Charlson age-comorbidity index: 10, and mean glomerular filtration rate: 12.4 mL/min/1.73 m2). The median patient follow-up time (until death or until 31 December 2014) was 165 days. During this period, 51% of patients did not have to visit the hospital’s emergency department and 58% did not require hospitalization. Forty-eight of the 76 patients died after a median time of 135 days in the program; 24 (50%) died at home. Our experience indicates that with the support of the Palliative Care Unit and the Nephrology Department, ACKD patients who are not dialysis candidates may be monitored at home by Primary Care Teams.

Trials raising concerns about erythropoiesis-stimulating agents, revisions to their labeling, and changes to practice guidelines and dialysis payment systems have provided strong stimuli to decrease erythropoiesis-stimulating agent use and increase intravenous iron administration in recent years. These factors have been associated with a rise in iron utilization, particularly among hemodialysis patients, and an unprecedented increase in serum ferritin concentrations. The mean serum ferritin concentration among United States dialysis patients in 2013 exceeded 800 ng/ml, with 18% of patients exceeding 1200 ng/ml. Although these changes are broad based, the wisdom of these practices is uncertain. Herein, we examine influences on and trends in intravenous iron utilization and assess the clinical trial, epidemiologic, and experimental evidence relevant to its safety and efficacy in the setting of maintenance dialysis. These data suggest a potential for harm from increasing use of parenteral iron in dialysis-dependent patients. In the absence of well powered, randomized clinical trials, available evidence will remain inadequate for making reliable conclusions about the effect of a ubiquitous therapy on mortality or other outcomes of importance to dialysis patients. Nephrology stakeholders have an urgent obligation to initiate well designed investigations of intravenous iron in order to ensure the safety of the dialysis population.

Automation, decision support, and expert systems in nephrology.

Increasing data suggest that errors in medicine occur frequently and result in substantial harm to the patient. The Institute of Medicine report described the magnitude of the problem, and public interest in this issue, which was already large, has grown. The traditional approach in medicine has been to identify the persons making the errors and recommend corrective strategies. However, it has become increasingly clear that it is more productive to focus on the systems and processes through which care is provided. If these systems are set up in ways that would both make errors less likely and identify those that do occur and, at the same time, improve efficiency, then safety and productivity would be substantially improved. Clinical decision support systems (CDSSs) are active knowledge systems that use 2 or more items of patient data to generate case specific recommendations. CDSSs are typically designed to integrate a medical knowledge base, patient data, and an inference engine to generate case specific advice. This article describes how automation, templating, and CDSS improve efficiency, patient care, and safety by reducing the frequency and consequences of medical errors in nephrology. We discuss practical applications of these in 3 settings: a computerized anemia-management program (CAMP, Henry Ford Health System, Detroit, MI), vascular access surveillance systems, and monthly capitation notes in the hemodialysis unit.

Urinary tract infection in children: Diagnosis, treatment, imaging - Comparison of current guidelines.

Urinary tract infection (UTI) is a frequent disorder of childhood, yet the proper approach for a child with UTI is still a matter of controversy. The objective of this study was to critically compare current guidelines for the diagnosis and management of UTI in children, in light of new scientific data. An analysis was performed of the guidelines from: American Academy of Pediatrics (AAP), National Institute for Health and Care Excellence (NICE), Italian Society of Pediatric Nephrology, Canadian Paediatric Society (CPS), Polish Society of Pediatric Nephrology, and European Association of Urology (EAU)/European Society for Pediatric Urology (ESPU). Separate aspects of the approach for a child with UTI, including diagnosis, treatment and further imaging studies, were compared, with allowance for recent research in each field. The analyzed guidelines tried to reconcile recent reports about diagnosis, treatment, and further diagnostics in pediatric UTI with prior practices and opinions, and economic capabilities. There was still a lack of sufficient data to formulate coherent, unequivocal guidelines on UTI management in children, with imaging tests remaining the main area of controversy. As a result, the authors formulated their own proposal for UTI management in children. Copyright © 2017 Journal of Pediatric Urology Company. Published by Elsevier Ltd. All rights reserved.

The European patents for epoetin alpha recently expired. Biosimilars (i.e. "a medicine which is similar to a biological medicine that has already been authorized" [EMEA 2007]) of epoetins have thus been released on the market in Europe. Because of the complexity of the processes that are required to produce medicinal products containing biotechnology-derived proteins as active substances and to characterize the physicochemical properties of these compounds, the guidelines that have been developed for generic drugs cannot be used for approval of biosimilar products. The EMEA guidelines do not answer all questions that have been raised for the development of biosimilars, and in some cases, decisions will have to be taken at a national level. This is why the Society of Nephrology (Société de néphrologie), the French-speaking Society of Dialysis (Société francophone de dialyse) and the Pediatric Society of Nephrology (Société de néphrologie pédiatrique) established guidelines for the usage of biosimilar epoetins concerning approval, identification, substitution of an innovator drug, post-marketing surveillance, extension of indication and pharmacovigilance plan.

Idiopathic nephrotic syndrome is the most common glomerular disease in childhood, affecting 1 to 3 per 100,000 children under the age of 16. It most commonly occurs in ages between 2 and 10. Its cause is unknown, and its histology corresponds to minimal change disease in 90% of cases, or focal segmental glomerulosclerosis. Steroid-resistant nephrotic syndrome represents 10-20% of idiopathic nephrotic syndrome in pediatrics. It has a poor prognosis, and its management is a significant therapeutic challenge. Half of patients evolve to end-stage renal disease within 5 years, and are additionally exposed to complications secondary to persistent NS and to the adverse effects of immunosuppressive therapy. The primary goal of treatment is to achieve complete remission, but even a partial remission is associated with a better renal survival than the lack of response. This paper is the result of the collaborative effort of the Nephrology Branch of the Chilean Society of Pediatrics with aims at helping pediatricians and pediatric nephrologists to treat pediatric idiopathic nephrotic syndrome. In this second part, handling of steroid-resistant nephrotic syndrome as well as nonspecific therapies are discussed. Copyright © 2015 Sociedad Chilena de Pediatría.

Because of its multi-organ involvement, the syndrome of sepsis provides clinical challenges to a wide variety of health care providers. While multi-organ dysfunction triggered by sepsis requires general supportive critical care provided by intensivists, the impact of sepsis on renal function and the ability of renal replacement therapies to modulate its biologic consequences provide a significant opportunity for pediatric nephrologists and related care providers to impact outcomes. In this review, we aim to highlight newer areas of understanding of the pathobiology of sepsis with special emphasis on those aspects of particular interest to pediatric nephrology. As such, we aim to: (1) review the definition of sepsis and discuss advances in our mechanistic understanding of sepsis; (2) review current hypotheses regarding sepsis-induced acute kidney injury (AKI) and describe its epidemiology based on evolving definitions of AKI; (3) review the impact of renal failure on the immune system, highlighting the sepsis risk in this cohort and strategies that might minimize this risk; (4) review how renal replacement therapeutic strategies may impact sepsis-induced AKI outcomes. By focusing the review on these specific areas, we have omitted other important areas of the biology of sepsis and additional interactions with renal function from this discussion; however, we have aimed to provide a comprehensive list of references that provide contemporary reviews of these additional areas.

Women: medicine, their kidneys, and nephrology.

As an act of compassion, the art of caring for the sick has always depended on women. As a practical tradition of healing skills, the "wise" and "old" women of antiquity were the original founders of what would ultimately become medicine. Throughout the subsequent millennia that it took for the gradual transformation of the healing skills from a craft to a profession, women continued to contribute to its progress and development. Unfortunately, recorded history has marginalized much of their fundamental contributions because most extant and investigated medical texts of the past were authored by men. As medicine began to embrace the basic sciences and became a university-based and regulated profession, rules excluding women from entry into the profession were made stricter and more rigorously enforced. It is only in the latter half of the 19th century that, in the footsteps of the growing feminine movement, women were admitted to medical schools, and in the 20th century that they began to contribute in earnest to the science of medicine. This article recounts this progress and highlights how it affected our knowledge of kidney disease in women and the enlarging role of women in the relatively new discipline of nephrology.

Children with chronic kidney disease (CKD), requiring dialysis or kidney transplantation, have a mortality rate of up to 30-fold higher than the general aged-matched population, and severely impaired quality of life. Symptoms such as fatigue and pain are prevalent and debilitating. Children with CKD are at risk of cognitive impairment, and poorer educational, vocational, and psychosocial outcomes compared with their well peers, which have consequences through to adulthood. Treatment regimens for children with CKD are long-term, complex, and highly intrusive. While many trials have been conducted to improve outcomes in children with CKD, the outcomes measured and reported are often not relevant to patients and clinicians, and are highly variable. These problems can diminish the value of trials as a means to improve the lives of children with CKD. The Standardised Outcomes in Nephrology-Children and Adolescents (SONG-Kids) study aims to develop a core outcome set for trials in children and adolescents with any stage of CKD that is based on the shared priorities of all stakeholders. SONG-Kids involves five phases: a systematic review to identify outcomes (both domains and measures) that have been reported in randomised controlled trials involving children aged up to 21 years with CKD; focus groups (using nominal group technique) with adolescent patients and caregivers of paediatric patients (all ages) to identify outcomes that are relevant and important to patients and their family and the reasons for their choices; semistructured key informant interviews with health professionals involved in the care of children with CKD to ascertain their views on establishing core outcomes in paediatric nephrology; an international three-round online Delphi survey with patients, caregivers, clinicians, researchers, policy-makers, and members from industry to develop consensus on important outcome domains; and a stakeholder workshop to review and finalise the set of core outcome domains for trials in children with CKD (including nondialysis-dependent, dialysis, and kidney transplantation). Establishing a core outcome set to be reported in all trials conducted in children with any stage of CKD will enhance the relevance, transparency, and impact of research to improve the lives of children and adolescents with CKD.

PKD2-related autosomal dominant polycystic kidney disease (ADPKD) is widely acknowledged to be of milder severity than PKD1-related disease, but population-based studies depicting the exact burden of the disease are lacking. We aimed to revisit PKD2 prevalence, clinical presentation, mutation spectrum, and prognosis through the Genkyst cohort. Case series, January 2010 to March 2016. Genkyst study participants are individuals older than 18 years from 22 nephrology centers from western France with a diagnosis of ADPKD based on Pei criteria or at least 10 bilateral kidney cysts in the absence of a familial history. Publicly available whole-exome sequencing data from the ExAC database were used to provide an estimate of the genetic prevalence of the disease. Molecular analysis of PKD1 and PKD2 genes. Renal survival, age- and sex-adjusted estimated glomerular filtration rate. The Genkyst cohort included 293 patients with PKD2 mutations (203 pedigrees). PKD2 patients with a nephrology follow-up corresponded to 0.63 (95% CI, 0.54-0.72)/10,000 in Brittany, while PKD2 genetic prevalence was calculated at 1.64 (95% CI, 1.10-3.51)/10,000 inhabitants in the European population. Median age at diagnosis was 42 years. Flank pain was reported in 38.9%; macroscopic hematuria, in 31.1%; and cyst infections, in 15.3% of patients. At age 60 years, the cumulative probability of end-stage renal disease (ESRD) was 9.8% (95% CI, 5.2%-14.4%), whereas the probability of hypertension was 75.2% (95% CI, 68.5%-81.9%). Although there was no sex influence on renal survival, men had lower kidney function than women. Nontruncating mutations (n=36) were associated with higher age-adjusted estimated glomerular filtration rates. Among the 18 patients with more severe outcomes (ESRD before age 60), 44% had associated conditions or nephropathies likely to account for the early progression to ESRD. Younger patients and patients presenting with milder forms of PKD2-related disease may not be diagnosed or referred to nephrology centers. Patients with PKD2-related ADPKD typically present with mild disease. In case of accelerated degradation of kidney function, a concomitant nephropathy should be ruled out.

Palliative care services, until recently, were mainly restricted to cancer patients with incurable diseases. Hence, evaluative studies of palliative care are sparse in areas other than oncology. To estimate what proportion of patients attending the Departments of Neurology, Cardiology, and Nephrology of Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Puducherry, required palliative care and to identify the palliative care needs of those patients. This was an exploratory descriptive study conducted in the three departments of JIPMER. There was no predetermined sample size for the study. The participants were all adult inpatients and outpatients who were in need of palliative care in the departments of Cardiology, Nephrology, and Neurology on the day of study. Percentage distribution was used to analyze the categorical variables such as education, gender, age, patients in need of palliative care, and their needs. The study showed that one in ten non-cancer patients in tertiary care hospitals may require palliative care services. Apart from issues in physical domain, a substantial proportion of participants also had issues in the psychological, emotional, and financial domains. This study highlights the need for incorporation and initiation of palliative care services in other non-cancer specialties in tertiary care hospitals to ensure holistic management of such cases. Counseling service has also to be rendered as part of palliative care since a good share of the patients had psychological and emotional issues.

Fatigue is one of the most highly prioritized outcomes for patients and clinicians, but remains infrequently and inconsistently reported across trials in hemodialysis. We convened an international Standardized Outcomes in Nephrology-Hemodialysis (SONG-HD) consensus workshop with stakeholders to discuss the development and implementation of a core outcome measure for fatigue. 15 patients/caregivers and 42 health professionals (clinicians, researchers, policy makers, and industry representatives) from 9 countries participated in breakout discussions. Transcripts were analyzed thematically. 4 themes for a core outcome measure emerged. Drawing attention to a distinct and all-encompassing symptom was explicitly recognizing fatigue as a multifaceted symptom unique to hemodialysis. Emphasizing the pervasive impact of fatigue on life participation justified the focus on how fatigue severely impaired the patient's ability to do usual activities. Ensuring relevance and accuracy in measuring fatigue would facilitate shared decision making about treatment. Minimizing burden of administration meant avoiding the cognitive burden, additional time, and resources required to use the measure. A core outcome measure that is simple, is short, and includes a focus on the severity of the impact of fatigue on life participation may facilitate consistent and meaningful measurement of fatigue in all trials to inform decision making and care of patients receiving hemodialysis.

The future management of nephrology: budget elements and organization planning.

PubMed

Quintaliani, Giuseppe; Panella, Vincenzo; Antonini, Giacomo

2003-01-01

Like many specialized branches of medicine, the future of nephrology will be entrusted to organizational models that are able to withstand the impact of both the new and increasing demand for assistance and the rationalization of resources. Therefore, it is necessary to clearly understand that the model must integrate and unify many aspects that regulate the activities in the health care service. Budget means "who does what and with material and what human resources" with respect to the constraints imposed by the decisions of the controlling entities, and it is mainly a system of planning and control. Management control utilizes a combined and coordinated synthesis of various company techniques including an auditing system, analytical accounting (or per cents of cost), a reporting system able to change the data gathered into measures of syntheses that can be used to carry out sound evaluations. The health system needs a type of organization--typical of professional organizations--that is an absolute prerogative of the technical/professional component which is the only one able to discern, understand and propose new diagnostic and therapeutic trends and approaches. At the end an evaluation of quality system is depicted. ISO 9004 norms, for example, provide principles on which an organization must be based, in order to reach high levels of quality and that must be used by the top management to lead the organization towards improved performance.

We present a consensus report pertaining to the improved clarity of definitions and classification of glomerular lesions in lupus nephritis that derived from a meeting of 18 members of an international nephropathology working group in Leiden, Netherlands, in 2016. Here we report detailed recommendations on issues for which we can propose adjustments based on existing evidence and current consensus opinion (phase 1). New definitions are provided for mesangial hypercellularity and for cellular, fibrocellular, and fibrous crescents. The term "endocapillary proliferation" is eliminated and the definition of endocapillary hypercellularity considered in some detail. We also eliminate the class IV-S and IV-G subdivisions of class IV lupus nephritis. The active and chronic designations for class III/IV lesions are replaced by a proposal for activity and chronicity indices that should be applied to all classes. In the activity index, we include fibrinoid necrosis as a specific descriptor. We also make recommendations on issues for which there are limited data at present and that can best be addressed in future studies (phase 2). We propose to proceed to these investigations, with clinicopathologic studies and tests of interobserver reproducibility to evaluate the applications of the proposed definitions and to classify lupus nephritis lesions.

Medical education reform is underway, but the optimal course for change has yet to be seen. While planning for the redesign of a renal physiology course at the Duke School of Medicine, the authors used a Q-sort survey to assess students' attitudes and learning preferences to inform curricular change. The authors invited first-year medical students at the Duke School of Medicine to take a Q-sort survey on the first day of renal physiology. Students prioritized statements related to their understanding of renal physiology, learning preferences, preferred course characteristics, perceived clinical relevance of renal physiology, and interest in nephrology as a career. By-person factor analysis was performed using the centroid method. Three dominant factors were strongly defined by learning preferences: “readers” prefer using notes, a textbook, and avoid lectures; “social-auditory learners” prefer attending lectures, interactivity, and working with peers; and “visual learners” prefer studying images, diagrams, and viewing materials online. A smaller, fourth factor represented a small group of students with a strong predisposition against renal physiology and nephrology. In conclusion, the Q-sort survey identified and then described in detail the dominant viewpoints of our students. Learning style preferences better classified first-year students rather than any of the other domains. A more individualized curriculum would simultaneously cater to the different types of learners in the classroom. PMID:26330030

Both enalapril and losartan are effective and widely used in patients with chronic kidney disease (CKD). This review aimed to evaluate the benefits of enalapril and losartan in adults with CKD. PubMed, EMBASE, the Cochrane Library and ClinicalTrials.gov were searched, without language limitations, for randomized controlled trials (RCT), in which enalapril and losartan were compared in adults with CKD. Standard methods, consistent with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, were used. Reviewer Manager software, ver. 5.2, was used for meta-analysis. Of 318 citations retrieved, 17 RCT (14 parallel-group and three cross-over) met our inclusion criteria. The pooled analysis for parallel RCT showed that the effects of enalapril and losartan on blood pressure, renal function and serum uric acid (UA) were similar. Meta-analysis indicated that patients taking enalapril had a higher risk of dry cough (risk ratio, 2.88; 95% CI, 1.11-7.48; P=0.03). Sensitivity analysis showed good robustness of these findings. Enalapril has similar effects to losartan on systemic blood pressure, renal function and serum UA in patients with CKD, but carries a higher risk of dry cough. Larger trials are required to evaluate the effects of these medications on clinical outcomes. © 2013 The Authors. Nephrology © 2013 Asian Pacific Society of Nephrology.

Concomitant presence of endothelial nitric oxide 894T and angiotensin II-converting enzyme D alleles are associated with diabetic nephropathy in a Kurdish population from Western Iran.

The present study investigated the influence of insertion (I)/deletion (D) polymorphism of the angiotensin II-converting enzyme (ACE) gene in combination with endothelial nitric oxide (eNOS) G894T polymorphism on the predisposition to diabetic nephropathy (DN). Using polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism (PCR-RFLP) method, the ACE and eNOS polymorphisms were genotyped in 72 microalbuminuric, 68 macroalbuminuric and 72 normoalbuinuric type 2 diabetes mellitus (T2DM) patients from Western Iran. The presence of eNOS T or ACE D allele was not associated with increased risk of macroalbuminuria (odds ratio (OR) = 1.36, P = 0.27 and OR = 1.6, P = 0.062, respectively). However, in the presence of both alleles there was a trend towards increased risk of macroalbuminuria (fivefold, P = 0.05). Our study indicates that the concomitant presence of both ACE D and eNOS T alleles tends to be associated with an elevation risk of macroalbuminuria compared with the presence of each polymorphism alone. This risk could be attributed to the increasing activity of ACE and angiotensin II level in the presence of D allele and decreasing NO production in the presence of T allele accelerating diabetic nephropathy. © 2011 The Authors.

To evaluate their prognosis, the damage by melamine on children's kidney and other organs, and its influence on the children's development, was investigated. Nine hundred and sixty-two Chinese children were divided into three groups: group A, 265 children diagnosed with melamine-associated urolithiasis; group B, 197 children with a history of melamine-contaminated milk powder consumption but without urolithiasis; and group C, 500 healthy children. They were examined at 0, 1, 3, 6 and 12 months. The factors influencing the prognosis were investigated. The stone discharge was monitored by ultrasonography. Overt renal and liver damage and underlying renal injury markers were analyzed. The stone discharge rates 1, 3, 6 and 12 months after the diagnoses were 52.5%, 67.2%, 88.3% and 95.5%, respectively. Stone size was a stable influencing factor for the stone discharge rate. Additionally, the values of the potential renal injury markers in children with stones already discharged is equivalent to normal children. This 12 month follow up of early renal injury markers indicated that the damage to the kidney is temporary with no persistent negative outcomes being found till now. Additionally, the gross development of the children seemed not yet jeopardized by melamine. Longer-term follow up will be conducted. © 2011 The Authors.

Optimizing care for Canadians with diabetic nephropathy in 2015.

PubMed

Lloyd, Alissa; Komenda, Paul

2015-06-01

Diabetic chronic kidney disease (CKD) is the cause of kidney failure in approximately 35% of Canadian patients requiring dialysis. Traditionally, only a minority of patients with type 2 diabetes and CKD progress to kidney failure because they die of a cardiovascular event first. However, with contemporary therapies for diabetes and cardiovascular disease, this may no longer be true. The classic description of diabetic CKD is the development of albuminuria followed by progressive kidney dysfunction in a patient with longstanding diabetes. Many exciting candidate agents are under study to halt the progression of diabetic CKD; current therapies center on optimizing glycemic control, renin angiotensin system inhibition, blood pressure control and lipid management. Lifestyle modifications, such as salt and protein restriction as well as smoking cessation, may also be of benefit. Unfortunately, these accepted therapies do not entirely halt the progression of diabetic CKD. Also unfortunately, the presence of CKD in general is under-recognized by primary care providers, which can lead to late referral, missed opportunities for preventive care and inadvertent administration of potentially harmful interventions. Not all patients require referral to nephrology for diagnosis and management, but modern risk-prediction algorithms, such as the kidney failure risk equation, may help to guide referral appropriateness and dialysis modality planning in subspecialty nephrology multidisciplinary care clinics.

The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Central Repositories, part of the National Institutes of Health (NIH), are an important resource available to researchers and the general public. The Central Repositories house samples, genetic data, phenotypic data, and study documentation from >100 NIDDK-funded clinical studies, in areas such as diabetes, digestive disease, and liver disease research. The Central Repositories also have an exceptionally rich collection of studies related to kidney disease, including the Modification of Diet in Renal Disease landmark study and recent data from the Chronic Renal Insufficiency Cohort and CKD in Children Cohort studies. The data are carefully curated and linked to the samples from the study. The NIDDK is working to make the materials and data accessible to researchers. The Data Repositories continue to improve flexible online searching tools that help researchers identify the samples or data of interest, and NIDDK has created several different paths to access the data and samples, including some funding initiatives. Over the past several years, the Central Repositories have seen steadily increasing interest and use of the stored materials. NIDDK plans to make more collections available and do more outreach and education about use of the datasets to the nephrology research community in the future to enhance the value of this resource.

This study sought to examine the effect of n-3 supplementation on lipoprotein(a) (Lp(a)) levels in end-stage renal disease (ESRD) patients undergoing chronic hemodialysis. The present study was conducted using a double-blind, permuted-randomized, controlled experimental protocol. This study took place at the Central Texas Nephrology Associates Dialysis Clinic (Waco, TX). Patients with ESRD and associated with the Central Texas Nephrology Associates who were undergoing chronic hemodialysis participated in this study. Patients with ESRD were followed prospectively while receiving supplements of fish oil (treatment, eicosapentaenoic acid, 0.96g/day, and docosahexaenoic acid, 0.6g/day) or corn oil (control subjects) for 6 months. After a 12-hour fast, participants donated 12mL of blood for analysis of Lp(a) at baseline and at 6 months. The comparison of Lp(a) concentration by group at 6 months was the primary outcome measure of the study. Our study suggests that fish-oil supplementation did not decrease levels of Lp(a) (P=.66), compared with control subjects. We failed to show a significant effect of 6 months of over-the-counter fish-oil supplementation on Lp(a) status in an ESRD population, although results from this study support findings from other studies suggesting that African Americans have higher Lp(a) concentrations than persons of Caucasian decent.

Toward population management in an integrated care model.

Under the Patient Protection and Affordable Care Act of 2010, accountable care organizations (ACOs) will be the primary mechanism for achieving the dual goals of high-quality patient care at managed per capita costs. To achieve these goals in the newly emerging health care environment, the nephrology community must plan for and direct integrated delivery and coordination of renal care, focusing on population management. Even though the ESRD patient population is a complex group with comorbid conditions that may confound integration of care, the nephrology community has unique experience providing integrated care through ACO-like programs. Specifically, the recent ESRD Management Demonstration Project sponsored by the Centers for Medicare & Medicaid Services and the current ESRD Prospective Payment System with it Quality Incentive Program have demonstrated that integrated delivery of renal care can be accomplished in a manner that provides improved clinical outcomes with some financial margin of savings. Moving forward, integrated renal care will probably be linked to provider performance and quality outcomes measures, and clinical integration initiatives will share several common elements, namely performance-based payment models, coordination of communication via health care information technology, and development of best practices for care coordination and resource utilization. Integration initiatives must be designed to be measured and evaluated, and, consistent with principles of continuous quality improvement, each initiative will provide for iterative improvements of the initiative.

Blood specimen labelling errors: Implications for nephrology nursing practice.

Duteau, Jennifer

2014-01-01

Patient safety is the foundation of high-quality health care, as recognized both nationally and worldwide. Patient blood specimen identification is critical in ensuring the delivery of safe and appropriate care. The practice of nephrology nursing involves frequent patient blood specimen withdrawals to treat and monitor kidney disease. A critical review of the literature reveals that incorrect patient identification is one of the major causes of blood specimen labelling errors. Misidentified samples create a serious risk to patient safety leading to multiple specimen withdrawals, delay in diagnosis, misdiagnosis, incorrect treatment, transfusion reactions, increased length of stay and other negative patient outcomes. Barcode technology has been identified as a preferred method for positive patient identification leading to a definitive decrease in blood specimen labelling errors by as much as 83% (Askeland, et al., 2008). The use of a root cause analysis followed by an action plan is one approach to decreasing the occurrence of blood specimen labelling errors. This article will present a review of the evidence-based literature surrounding blood specimen labelling errors, followed by author recommendations for completing a root cause analysis and action plan. A failure modes and effects analysis (FMEA) will be presented as one method to determine root cause, followed by the Ottawa Model of Research Use (OMRU) as a framework for implementation of strategies to reduce blood specimen labelling errors.

Idiopathic nephrotic syndrome is the most common glomerular disease in childhood, affecting 1 to 3 per 100,000 children under the age of 16. It most commonly occurs in ages between 2 and 10. Its cause is unknown and its histology corresponds to minimal change disease in 90% of cases, or focal segmental glomerulosclerosis. 80 to 90% of cases respond to steroids (steroid-sensitive nephrotic syndrome) with good prognosis and long-term preservation of renal function over time. 70% of patients with SSNS have one or more relapses in their evolution, and of these, 50% behave as frequent relapsing or steroid-dependent, a group that concentrate the risk of steroid toxicity. Patients with steroid-resistant nephrotic syndrome have a poor prognosis and 50% of them evolve to end-stage renal disease. The goal of therapy is to induce and maintain remission of the disease, reducing the risk secondary to proteinuria while minimizing the adverse effects of treatments, especially with prolonged use of corticosteroids. This paper is the result of the collaborative effort of the Nephrology Branch of the Chilean Society of Pediatrics with aims at helping pediatricians and pediatric nephrologists to treat pediatric SNI. In this first part, recommendations of steroid-sensitive nephrotic syndrome are discussed. Copyright © 2015 Sociedad Chilena de Pediatría. Publicado por Elsevier España, S.L.U. All rights reserved.

Issues regarding 'immortal time' in the analysis of the treatment effects in observational studies.

In observational studies, treatment is often time dependent. Mishandling the time from the beginning of follow-up to treatment initiation can result in bias known as immortal time bias. Nephrology researchers who conduct observational research must be aware of how immortal time bias can be introduced into analyses. We review immortal time bias issues in time-to-event analyses in the biomedical literature and give examples from the nephrology literature. We also use simulations to quantify the bias in different methods of mishandling immortal time; intuitively explain how bias is introduced when immortal time is mishandled; raise issues regarding unadjusted treatment comparison, patient characteristics comparison, and confounder adjustment; and, using data from DaVita Inc., linked with the Centers for Medicare & Medicaid Services end-stage renal disease database, show that the severity of bias and the issues described can occur in actual data analyses of patients with end-stage renal disease. In the simulation examples, mishandling immortal time led to an underestimated hazard ratio (treatment vs. control), thus an overestimated treatment effect, by as much as 96%, and an overestimated hazard ratio by as much as 138%, depending on the distribution of 'survival' time and the method used. Results from the DaVita data were consistent with the simulation. Careful consideration of methodology is needed in observational analyses with time-dependent treatment.

Vascular access for haemodialysis is key in renal patients both due to its associated morbidity and mortality and due to its impact on quality of life. The process, from the creation and maintenance of vascular access to the treatment of its complications, represents a challenge when it comes to decision-making, due to the complexity of the existing disease and the diversity of the specialities involved. With a view to finding a common approach, the Spanish Multidisciplinary Group on Vascular Access (GEMAV), which includes experts from the five scientific societies involved (nephrology [S.E.N.], vascular surgery [SEACV], vascular and interventional radiology [SERAM-SERVEI], infectious diseases [SEIMC] and nephrology nursing [SEDEN]), along with the methodological support of the Cochrane Center, has updated the Guidelines on Vascular Access for Haemodialysis, published in 2005. These guidelines maintain a similar structure, in that they review the evidence without compromising the educational aspects. However, on one hand, they provide an update to methodology development following the guidelines of the GRADE system in order to translate this systematic review of evidence into recommendations that facilitate decision-making in routine clinical practice, and, on the other hand, the guidelines establish quality indicators which make it possible to monitor the quality of healthcare.

Scientific societies are increasingly seen as central to the advancement of information sharing and collaboration among scientists and clinical investigators for the progress of medical research and the promotion of education, professional competence, integrity and quality studies. To more effectively serve the practicing nephrologists and investigators dedicated to renal science, the Council of the European Renal Association and European Dialysis and Transplantation Association (ERA-EDTA) reorganized and integrated the various activities of the society into two branches, the Clinical Nephrology Governance branch and the Renal Science branch. New affordable initiatives to promote research, education and professional development and to advocate for the recognition of chronic kidney disease as a major public health issue at the European level will be put in place and/or potentiated in the new organizational frame. Educational initiatives will be espoused to Continuous Professional Development and, starting from 2019, 14 Education & Continuous Professional Development courses will be held covering the full range of knowledge areas of modern nephrology. Consolidation and development is the short- and medium-term mantra of the ERA-EDTA. The society has a rich portfolio of successful activities and brilliant, creative scientists among its members. Integrating the various activities of the ERA-EDTA and treasuring the expertise and wisdom of its most accomplished members will facilitate collaborative research, education and its public impact at large.

2012-11-01

The percentage of people in Australia who undertake home dialysis has steadily decreased over the past 40 years and varies within Australia. Consumer factors related to this decline have not previously been determined. A 78-question survey was developed and piloted in 2008 and 2009. Survey forms were distributed to all adult routine dialysis patients in all Australian states and territories (except Northern Territory) between 2009 and 2010. Of 9223 distributed surveys, 3250 were completed and returned. 49% of respondents indicated they had no choice in the type of dialysis and 48% had no choice in dialysis location. Respondents were twice as likely to receive information about haemodialysis (85%) than APD (39%) or CAPD (41%). The provision of education regarding home modalities differed significantly between states, and decreased with increasing patient age. Additional nursing support and reimbursement of expenses increased the proportion of those willing to commence dialysis at home, from 13% to 34%. State differences in the willingness to consider home dialysis, the degree of choice in dialysis location, the desire to change current dialysis type and/or location, and the provision of information about dialysis were identified. The delivery of pre-dialysis education is variable, and does not support all options of dialysis for all individuals. State variances indicate that local policy and health professional teams significantly influence the operation of dialysis programs. © 2012 The Authors.

A decade review: methods to improve adherence to the treatment among haemodialysis patients.

PubMed

Morgan, L

2001-01-01

Haemodialysis patients are asked to adhere to a very difficult treatment regimen consisting of fluid and diet restrictions, many daily medications, and usually 3 or 4 hour haemodialysis sessions three times each week. Many haemodialysis patients fail to adhere to their prescribed treatment and although this regimen is difficult, it is necessary for patients to adhere for optimal health and well-being. It is important for nephrology nurses to know what interventions help patients overcome the barriers that keep them from adhering to prescribed treatment The purpose of this paper is to review the literature to examine the research that has been published on methods to improve adherence among haemodialysis patients. Behavioural approaches, education, and primary nursing are interventions that have been researched More research has been reported on the demographics of noncompliant haemodialysis patients than on effective methods that help patients improve adherence to the treatment regimen. Demographic characteristics do not consistently predict compliance for individual patients. Each patient is unique. Research supports the idea that the nephrology nurse should spend time with the patient on a regular basis in order to understand the factors that hinder the individual patient from adhering to the treatment regimen. The nurse who knows the patient well is empowered to develop individualised interventions aimed at reducing barriers that interfere with the patient's ability to adhere to treatment.

Overseas kidney transplantation has often been reported to have unsatisfactory outcomes. This study aims to compare post-transplantation outcomes between overseas and domestic kidney transplant (KT) recipients in Taiwan. The Taiwanese National Health Insurance Research Database was used to identify 310 domestic and 643 overseas KT recipients, who survived for longer than 1 month after the transplantation, in a cohort of 45,453 chronic haemodialysis patients in 1997-2002. Cox proportional hazards models were used to assess risks of mortality and graft failure. The 1, 3 and 5 year survival rates for domestic KT recipients were 96.5%, 93.3% and 91.6%, respectively, while those for overseas KT recipients were 94.9%, 87.9% and 77.1%, respectively (P = 0.015). For the overseas group, those who received a KT before 2001 had significantly higher hazard ratios of mortality and graft failure (2.85 and 1.71, respectively). However, for those receiving a KT in 2001-2002, no significant outcome difference could be found between overseas and domestic recipients. The risk disparity between overseas and domestic KT recipients is mainly attributable to when the transplantation was performed. In attempting to dissuade potential recipients from organ trafficking, merely emphasizing the previously acknowledged poor outcomes no longer suffices as a valid reason. © 2011 The Authors.

Recently, 4 new risk scores for the prediction of mortality and cardiovascular events were especially tailored for hemodialysis patients; these scores performed much better than previous scores. Tripepi et al. found that these risk scores were even more predictive for all-cause and cardiovascular death than the measurement of the left ventricular mass index was. Nevertheless, the investigation of left ventricular mass and function has its own place for other reasons. Copyright © 2016 International Society of Nephrology. Published by Elsevier Inc.

Obstetric nephrology: preeclampsia--the nephrologist's perspective.

Umans, Jason G

2012-12-01

Preeclampsia, a common and potentially devastating multisystem disorder unique to human pregnancy, represents a novel form of secondary hypertension with complex renal and systemic effects. Recent translational and clinical research reveals key pathophysiologic contributions due to dysregulation of angiogenic factors and of angiotensin signaling. Despite these insights, there are still difficulties in the clinical definition of preeclampsia and in the diagnosis of women with this disorder. Although recent research suggests the potential for new preventive and treatment strategies, most have not yet been shown ready for clinical use.

Treatment of lupus nephritis is more evidenced-based than ever. Yet many areas of uncertainty persist. The article by Rathi et al. brings a piece to the puzzle by comparing, in a group of Indian patients, the Euro-Lupus low-dose i.v. cyclophosphamide regimen with mycophenolate mofetil. Although some caveats must be raised, the results suggest that, after crossing the Atlantic, the Euro-Lupus regimen may well be moving East. Copyright © 2016 International Society of Nephrology.

McCarley, Patricia

2009-01-01

Patient empowerment is centered on the belief that patients should be in control of their own care and that behavioral changes and adherence to therapies cannot be achieved unless patients internalize the need for self-change. Data have consistently shown improved outcomes among patients on dialysis who are engaged, empowered and self-managing. Motivational interviewing provides a technique that can be applied by nephrology nurses to partner with patients and engage them in the management of their own care.

Patients receiving haemodialysis are exposed to a large volume of dialysis fluid. The Italian Society of Nephrology (ISN) has published guidelines and microbial quality standards on dialysis water (DW) and solutions to ensure patient safety. To identify microbial and chemical hazards, and evaluate the quality of disinfection treatment in DW plants. In 2015 and 2016, water networks and DW plants (closed loop and online monitors) of nine dialysis wards of Italian hospitals, hosting 162 dialysis beds overall, were sampled on a monthly basis to determine the parameters provided by ISN guidelines. Chlorinated drinking water was desalinated by reverse osmosis and distributed to the closed loop which feeds all online monitors. Disinfection with peracetic acid was performed in all DW plants on a monthly basis. Over the 24-month study period, seven out of nine DW plants (78%) recorded negative results for all investigated parameters. Closed loop contamination with Burkholderia cepacia was detected in a DW plant from January 2015 to March 2015. Pseudomonas aeruginosa was isolated from March 2016 to May 2016 in the closed loop of another DW plant. These microbial contaminations were eradicated by shock disinfection with sodium hypochlorite and peracetic acid, followed by water flushing. These results highlight the importance of chemical and physical methods of DW disinfection. The maintenance of control measures in water plants hosted in dialysis wards ensures a microbial risk reduction for all dialysis patients. Copyright © 2017 The Healthcare Infection Society.

Weale, Andy R

2013-09-01

Current systems in place in healthcare are designed to detect harm after it has happened (e.g critical incident reports) and make recommendations based on an assessment of that event. Safer Clinical Systems, a Health Foundation funded project, is designed to proactively search for risk within systems, rather than being reactive to harm. The aim of the Safer Clinical Systems project in Renal Care was to reduce the risks associated with shared care for patients who are undergoing surgery but are looked after peri-operatively by nephrology teams on nephrology wards. This report details our findings of the diagnostic phase of Safer Clinical Systems: the proactive search for risk. We have evaluated the current system of care using a set of risk evaluation and process mapping tools (Failure Modes and Effects Analysis (FMEA) and Hierarchical Task Analysis HTA). We have engaged staff with the process mapping and risk assessment tools. We now understand our system and understand where the highest risk tasks are undertaken during a renal in-patient stay during which a patient has an operation. These key tasks occur across the perioperaive period and are not confined to one aspect of care. A measurement strategy and intervention plan have been designed around these tasks. Safer Clinical Systems has identified high risk, low reliability tasks in our system. We look forward to fully reporting these data in 2014. © 2013 European Dialysis and Transplant Nurses Association/European Renal Care Association.

Aim There is discussion whether medicines can be authorized on the market based on evidence from surrogate endpoints. We assessed opinions of different stakeholders on this topic. Methods We conducted an online questionnaire that targeted various stakeholder groups (regulatory agencies, pharmaceutical industry, academia, relevant public sector organisations) and medical specialties (cardiology or nephrology vs. other). Participants were enrolled through purposeful sampling. We inquired for conditions under which surrogate endpoints can be used, the validity of various cardio-renal biomarkers and new approaches for biomarker use. Results Participants agreed that surrogate endpoints can be used when the surrogate is scientifically valid (5-point Likert response format, mean score: 4.3, SD: 0.9) or when there is an unmet clinical need (mean score: 3.8, SD: 1.2). Industry participants agreed to a greater extent than regulators and academics. However, out of four proposed surrogates (blood pressure (BP), HbA1c, albuminuria, CRP) for cardiovascular outcomes or end-stage renal disease, only use of BP for cardiovascular outcomes was deemed moderately accurate (mean: 3.6, SD: 1.1). Specialists in cardiology or nephrology tended to be more positive about the use of surrogate endpoints. Conclusion Stakeholders in drug development do not oppose to the use of surrogate endpoints in drug marketing authorization, but most surrogates are not considered valid. To solve this impasse, increased efforts are required to validate surrogate endpoints and to explore alternative ways to use them. PMID:25268242

This questionnaire-based cross-sectional survey reported the attitudes and practices of Chinese doctors regarding chronic kidney disease (CKD) and acute kidney injury (AKI) management. An online questionnaire consisting of general information, awareness of CKD and AKI, education status, renal laboratory items, and clinical practices between February 20, 2017 and August 15, 2017. Among the 1289 respondents from secondary and tertiary hospitals in 30 provinces, 718 (55.7%) were nephrologists, 94.3% had the ability to evaluate glomerular filtration rates, and 98.8% could evaluate urinary protein excretion, indicating that Chinese doctors met the minimum requirements to manage CKD. However, nearly half of all respondents reported that easy methods for spot urine creatinine-adjusted urinary protein assessments were unavailable. Awareness of the CKD risk stratification system and AKI definition was inadequate, and only 54.2% of respondents reported that they had received nutritional education for renal diseases. Although most of the respondents were nephrologists at university hospitals, 66.4% and 76.3% of respondents reported nephrology referrals and nephrology consultations, respectively, after AKI, suggesting an insufficient role for nephrologists. Finally, management models differed significantly, indicating that universal guidelines for CKD and AKI management are required across China. Several considerable challenges remain regarding CKD and AKI management in China, including inadequate knowledge and training systems, an absence of clinical protocols, and insufficient multidisciplinary cooperation.

Beyond linear methods of data analysis: time series analysis and its applications in renal research.

Analysis of temporal trends in medicine is needed to understand normal physiology and to study the evolution of disease processes. It is also useful for monitoring response to drugs and interventions, and for accountability and tracking of health care resources. In this review, we discuss what makes time series analysis unique for the purposes of renal research and its limitations. We also introduce nonlinear time series analysis methods and provide examples where these have advantages over linear methods. We review areas where these computational methods have found applications in nephrology ranging from basic physiology to health services research. Some examples include noninvasive assessment of autonomic function in patients with chronic kidney disease, dialysis-dependent renal failure and renal transplantation. Time series models and analysis methods have been utilized in the characterization of mechanisms of renal autoregulation and to identify the interaction between different rhythms of nephron pressure flow regulation. They have also been used in the study of trends in health care delivery. Time series are everywhere in nephrology and analyzing them can lead to valuable knowledge discovery. The study of time trends of vital signs, laboratory parameters and the health status of patients is inherent to our everyday clinical practice, yet formal models and methods for time series analysis are not fully utilized. With this review, we hope to familiarize the reader with these techniques in order to assist in their proper use where appropriate.

Management trends in early chronic kidney disease (CKD) and their associations with clinical outcomes have not previously been reported. We evaluated incident (Stage G3A) CKD patients from an integrated health care system in 2004-06, 2007-09 and 2010-12 to determine adjusted trends in screening (urinary protein quantification), treatment [prescription for angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB), and statin] and nephrology referral. For the same time periods, adjusted rates for mortality, progression to Stage G4 CKD and hospitalization for myocardial infarction or heart failure were calculated and compared across time periods. There were 728, 788 and 956 patients with incident CKD in 2004-06, 2007-09 and 2010-12, respectively. Adjusted rates of proteinuria quantification (31, 39 and 51 screens/100 person-years), statin prescription (53, 63 and 64 prescriptions/100 person-years) and nephrology referral (2, 3 and 5 referrals/100 person-years) all increased over time (P for trend <0.001 in all cases). ACEI/ARB prescription rates did not change (88, 83 and 80 prescriptions/100 person-years, P = 0.68). Adjusted death rates (7, 5 and 6 deaths/100 person-years), CKD progression (9, 10 and 7 progressors/100 person-years) and cardiovascular hospitalization (10, 8 and 9 hospitalizations per 100/person-years) did not change (P for trend >0.4 in all cases). In this integrated health care system, management of incident CKD over the past decade has intensified.

Chronic kidney disease (CKD) is a risk factor for the development of cardiovascular disease, which is the primary cause of morbidity and mortality in patients with CKD. Local data about cardiovascular risk factors among CKD patients is generally scanty. To determine the prevalence of the common cardiovascular risk factors among patients with CKD attending the nephrology out-patient clinic in Mulago national referral hospital in Uganda. This was a cross-sectional study in which 217 patients with a mean age of 43 years were recruited over a period of nine months. Data on demographic characteristics, risk factors for cardiovascular disease, complete blood count, renal function tests/electrolytes, and lipid profiles were collected using a standardised questionnaire. One hundred and eleven (51.2%) of the participants were male. Hypertension was reported in 90% of participants while cigarette smoking was present in 11.5%. Twenty-two participants (10.2%) were obese and 16.1% were diabetic. A total of 71.9% had a haemoglobin concentration < 11 g/dl, with the prevalence of anaemia increasing with advancing renal failure (p < 0.001); 44.7% were hypocalcaemic and 39.2% had hyperphosphataemia. The prevalence of abnormal calcium and phosphate levels was found to increase with declining renal function (p = 0.004 for calcium and p < 0.001 for phosphate). This study demonstrated that both traditional and non-traditional cardiovascular risk factors occurred frequently in patients with CKD attending the nephrology out-patient clinic at Mulago Hospital.

In addition to extending health insurance coverage, the Affordable Care Act of 2010 aims to improve quality of care and contain costs. To this end, the act allowed introduction of bundled payments for a range of services, proposed the creation of accountable care organizations (ACOs), and established the Centers for Medicare and Medicaid Innovation to test new care delivery and payment models. The ACO program began April 1, 2012, along with demonstration projects for bundled payments for episodes of care in Medicaid. Yet even before many components of the Affordable Care Act are fully in place, the Medicare ESRD Program has instituted legislatively mandated changes for dialysis services that resemble many of these care delivery reform proposals. The ESRD program now operates under a fully bundled, case-mix adjusted prospective payment system and has implemented Medicare's first-ever mandatory pay-for-performance program: the ESRD Quality Incentive Program. As ACOs are developed, they may benefit from the nephrology community's experience with these relatively novel models of health care payment and delivery reform. Nephrologists are in a position to assure that the ACO development will benefit from the ESRD experience. This article reviews the new ESRD payment system and the Quality Incentive Program, comparing and contrasting them with ACOs. Better understanding of similarities and differences between the ESRD program and the ACO program will allow the nephrology community to have a more influential voice in shaping the future of health care delivery in the United States.

Depression is one of the most common psychological disorders in end-stage renal disease (ESRD) patients and is associated with impaired quality of life and increased mortality and rate of hospitalization. We aimed to examine the contributions of depression and the use of antidepressive agents in the mortality of ESRD patients. A retrospective observatory study was conducted using the National Health Insurance Research Database in Taiwan. Patients with newly diagnosed as ESRD during the year 2001 to 2007 were collected. A total of 2312 ESRD patients were identified in the database. Statistical analyses were conducted to examine the contributions of depression and exposure of antidepressive agents in mortality rates of ESRD patients. Diagnosis of depression did not influence mortality rate (mortality rate in patients with depression: 26.5%; mortality rate in patients without depression: 26.2%; P= 1.000). Those who had antidepressive agents exposure had significantly higher mortality rate (mortality rate: 32.3%) than those who did not (mortality rate: 24.5%) (P < 0.001). Our findings suggest that (i) the mortality rate of ESRD patients was not affected by the diagnosis of depression, and (ii) exposure of antidepressive agents in ESRD patients was associated with a higher mortality rate. The high mortality rate in ESRD patients exposed to antidepressive agents can be a bias by indication. Equally, a true contribution of the antidepressive agents cannot be ruled out and this needs clarification. © 2012 The Authors. Nephrology © 2012 Asian Pacific Society of Nephrology.

Background: Lactobacillus plantarum 299v (LP299v) has been used in order to reduce gastrointestinal symptoms during antibiotic exposure. However, it remains controversial whether or not probiotics are effective in the prevention of Clostridium difficile infections (CDI) among patients receiving antibiotics. The aim of this study was to analyze the CDI among patients receiving antibiotics and hospitalized in the period before and after starting routine use of LP299v as a prevention of this infection. Methods: Among 3533 patients hospitalized in the nephrology and transplantation ward during a two-year period, 23 patients with CDI were diagnosed and enrolled in this retrospective study. Since November 2013, prevention of CDI with oral use of LP299v was performed in all patients treated with antibiotics and who were at a high risk of developing CDI. The observation period was divided into two twelve-month intervals before and after initiation of the use of LP299v as a prophylactic against CDI. Results: A significant (p = 0.0001) reduction of the number of cases of CDI was found after routinely using LP299v (n = 2; 0.11% of all hospitalized patients) compared with the previous twelve-month period of observation (n = 21; 1.21% of all hospitalized patients). Conclusions: Routine use of LP299v during treatment with antibiotics may prevent C. difficile infection in the nephrology and transplantation ward. PMID:26690209

Background and objectives Data on mineral metabolism in pediatric renal transplant recipients largely arise from small single-center studies. In adult patients, abnormal mineral levels are related to a higher risk of graft failure. This study used data from the European Society for Paediatric Nephrology/European Renal Association–European Dialysis and Transplant Association Registry to study the prevalence and potential determinants of mineral abnormalities, as well as the predictive value of a disturbed mineral level on graft survival in a large cohort of European pediatric renal transplant recipients. Design, setting, participants, & measurements This study included 1237 children (0–17 years) from 10 European countries, who had serum calcium, phosphorus, and parathyroid hormone measurements from 2000 onward. Abnormalities of mineral metabolism were defined according to European guidelines on prevention and treatment of renal osteodystrophy in children on chronic renal failure. Results Abnormal serum phosphorus levels were observed in 25% (14% hypophosphatemia and 11% hyperphosphatemia), altered serum calcium in 30% (19% hypocalcemia, 11% hypercalcemia), and hyperparathyroidism in 41% of the patients. A longer time since transplantation was associated with a lower risk of having mineral levels above target range. Serum phosphorus levels were inversely associated with eGFR, and levels above the recommended targets were associated with a higher risk of graft failure independently of eGFR. Conclusions Abnormalities in mineral metabolism are common after pediatric renal transplantation in Europe and are associated with graft dysfunction. PMID:25710805

Randomized controlled trials (RCTs) are important tools for evidence-based health care decisions. It is, therefore, important that they be conducted and reported with the highest possible standards. The aim of this study was to evaluate the reporting quality of the RCTs published in nephrology urology monthly journal and to examine whether there was a change over time in the reporting quality. The quality of each report was assessed using the Consolidated Standards of Reporting Trials (CONSORT) 2010 Statement checklist and a 5-point quality assessment instrument, i.e. the Jadad scale. Eighteen (14 Iranian and 4 non-Iranian) RCTs were published from 2012 to 2014 on topics including renal stone (16.6%), hemodialysis and transplantation (38.8%), and prostate conditions (11.1%). Interventions comprised surgery, drugs, and teaching method in 7 (38 %), 10 (55%), and 1 (5%) of them, respectively. According to the CONSORT checklist, the weakest reported items were registration number, identification as a randomized trial in the title, and settings and locations where the data were collected. The mean Jadad score of the reports was 2.72 ± 1.36 (54% of their maximum possible total score). According to the Jadad and CONSORT scales, there was an increase in the quality of reporting from 2012 to 2014. This assessment shows low reporting quality scores in reports. Training courses for researchers, using standard reporting tools (e.g. CONSORT 2010 Statement checklist), and consultation with methodologists can improve the quality of published RCTs.

Supportive Care: Communication Strategies to Improve Cultural Competence in Shared Decision Making.

PubMed

Brown, Edwina A; Bekker, Hilary L; Davison, Sara N; Koffman, Jonathan; Schell, Jane O

2016-10-07

Historic migration and the ever-increasing current migration into Western countries have greatly changed the ethnic and cultural patterns of patient populations. Because health care beliefs of minority groups may follow their religion and country of origin, inevitable conflict can arise with decision making at the end of life. The principles of truth telling and patient autonomy are embedded in the framework of Anglo-American medical ethics. In contrast, in many parts of the world, the cultural norm is protection of the patient from the truth, decision making by the family, and a tradition of familial piety, where it is dishonorable not to do as much as possible for parents. The challenge for health care professionals is to understand how culture has enormous potential to influence patients' responses to medical issues, such as healing and suffering, as well as the physician-patient relationship. Our paper provides a framework of communication strategies that enhance crosscultural competency within nephrology teams. Shared decision making also enables clinicians to be culturally competent communicators by providing a model where clinicians and patients jointly consider best clinical evidence in light of a patient's specific health characteristics and values when choosing health care. The development of decision aids to include cultural awareness could avoid conflict proactively, more productively address it when it occurs, and enable decision making within the framework of the patient and family cultural beliefs.

The incidence of chronic renal failure increase with the age. The selection of patient to dialysis has been increasing in spite of the high comorbidity. Moreover, in our clinical practice the aged patient is not contraindicated to dialysis. However, in the nephrology clinical practice not all the patients start the treatment with dialysis. OBJECTIVE The aim of our study has been to compare the characteristics of the patients who had not been dialyzed between the periods 1992-1995 and 2000-2003 to analyze the trend of the nephrology clinical practice. Comparative study of the characteristics and the evolution of patients with chronic renal failure in stage V, (renal failure) not incorporated to dialysis in one hospital during four years between the periods the 1992-1995 ( period A) and 2000-2003 (period B). Start dialysis (period A versus period B): 116 patients, age 59.9+15.5 years vs. 229 patients, age 64.0+15.8 years (p<0.05). Non-dialysis (period A versus period B): 38 patients, age 77.5+9.3 years vs. 37 patients, age 81.7+6.2 years (p<0.01). Renal function: serum creatinina 7.4+2.4 mg/dl vs. 5.3+1.2 mg/dl (p<0.001), MDRD estimate glomerular filtration 6.9+2.4 mg/dl ml/min/1.73 m2 vs. 10.0+2.3 ml/min/1.73 m2 (p<0.001). Primary renal disease: unknown etiology 31.5 % vs. 24.3 %, nephroangiosclerosis 23.6 % vs. 32.4 %, diabetes 28.9 % vs. 21.6 %. Functional status: dependent patients 34.2 % vs 83.8 % (p<0.001). The principal reason for non-dialysis were: personal decision: 26.3 % vs. 35.1 %, dementia 15.8 % vs. 29.7 %, brief life expectancy because of serious co-existing diseases 13.1 % vs. 21.7 % and serious chronic illness with inability for themselves care 44.7 % vs. 13.1 %. Comorbid conditions: 2.3+1.0 vs. 3.0+1.5 (p<0.05). Survival: 55+168 days vs. 168+236 days (p<0.001). Most of the patients that don't begin dialysis are elderly together with a poor functional capacity and with more autonomy in their decisions. The identification of patients with renal failure (stage V) was detected early in the last period than in the following one. The conservative management of non-dialyzed uremic patients is a significative nephrology clinical practice due to more survival of those persons.

With the rising incidence of metabolic syndrome and progressive kidney disease, efforts to halt this progression have become the mainstay of therapies in the era of modern nephrology. The necessity of one versus two kidneys has occupied the minds of leading scientists and philosophers throughout the ages and has laid the foundation for our understanding of progressive kidney disease. This review focuses on the major discoveries of the leading thinkers who with their paradigm shifting ideas and skepticism pushed the boundaries of our knowledge and shaped the theory of hyperfiltration.

The field of nephrology is actively involved in developing biomarkers and improving models for predicting patients’ risks of AKI and CKD and their outcomes. However, some important aspects of evaluating biomarkers and risk models are not widely appreciated, and statistical methods are still evolving. This review describes some of the most important statistical concepts for this area of research and identifies common pitfalls. Particular attention is paid to metrics proposed within the last 5 years for quantifying the incremental predictive value of a new biomarker. PMID:24855282

The prospective recognition of stenosis affecting dialysis vascular access and its prospective treatment is important in the management of the hemodialysis patient. Surveillance by physical examination is easily learned, easily performed, quickly done, and economical. In addition, it has a level of accuracy and reliability equivalent to other approaches that require special instrumentation. Physical examination should be part of any education to all hemodialysis care givers. This review presents the basic principles of physical examination of the hemodialysis vascular access and discusses the evidence behind its value.

Climate change represents a major global public health threat. The very provision of healthcare itself has a significant untoward effect on the environment, to which kidney care is likely to contribute disproportionately. In this article we describe the four principles we believe will underpin a successful transformation to lower carbon kidney care: disease prevention, patient empowerment, lean service delivery and the preferential use of low-carbon technologies. We illustrate their application and their co-benefits, such as improvements in patient care and reductions in cost, with examples. Copyright © 2010 S. Karger AG, Basel.

The limited spatial and temporal resolution of available methods for quantifying renal tissue oxygen tension is a major impediment to identification of the roles of renal hypoxia in kidney diseases. Intravital phosphorescence lifetime imaging microscopy allows cellular oxygen tension in the renal cortex of live animals to be resolved to the level of individual tubular cross-sections. This paves the way for future investigations of the spatial relationships between cellular hypoxia and pathophysiological events in kidney disease.

Patients with asymptomatic kidney stones have a high rate of progression to becoming symptomatic kidney stones when followed for several years. Small kidney stones are often found incidentally on imaging when evaluating patients for kidney donation, and there is a concern that after nephrectomy, the donor may become symptomatic and incur damage to the remaining kidney. We reviewed kidney donors at our institution with asymptomatic stones and surveyed them several years after donation to see if the stones became clinically active. © 2017 Asian Pacific Society of Nephrology.

Stressful ethical issues in uremia therapy.

The objectives of this review are to introduce and explore the following representative ethical problems generated by modern renal replacement therapy: (1) reviewing the historical origin of medical ethics with specific reference to nephrology; (2) recognizing the complex stresses surrounding assignment of a deceased donor renal transplant to a geriatric patient while young patients continue waiting for a donor kidney; and (3) appreciating the concept of futility and support for a uremic patient opting for death rather than further uremia therapy as the best in choice in coping with renal failure.

Holistic Care of Hemodialysis Access in Patients with Kidney Failure.

Kidney failure requiring hemodialysis is a chronic illness that has physical, psychosocial, and financial consequences. Patients with kidney failure receiving hemodialysis need a renewed focus on self-care, prevention, and community-based health management to reduce healthcare costs and complications, and improve outcomes and quality of life, while living with an altered lifestyle. A holistic chronic care model was applied as a guideline for healthcare professionals involved with this population to more effectively engage people with kidney failure in their management of their hemodialysis access.

Metabolic acidosis is commonly found in patients with chronic kidney disease (CKD), and its causes are: impaired ammonia excretion, reduced tubular bicarbonate reabsorption and insufficient renal bicarbonate production in relation to the amount of acids synthesised by the body and ingested with food. As the consequence, numerous metabolic abnormalities develop, which may lead to dysfunction of several organs. In observational studies, it has been found that CKD patients with metabolic acidosis are characterised by faster progression of kidney disease towards end stage kidney failure, and by increased mortality. Results of interventional studies suggest that alkali therapy in CKD patients slows progression of kidney disease. In view of these facts, the members of "The Working Group of the Polish Society of Nephrology on Metabolic and Endocrine Abnormalities in Kidney Diseases" have prepared the following statement and guidelines for the diagnosis and treatment of metabolic acidosis in CKD patients. Measurement of bicarbonate concentration in venous plasma or venous blood to check for metabolic acidosis should be performed in all CKD patients and metabolic acidosis in these patients should be diagnosed when the venous plasma or venous blood bicarbonate concentration is lower than 22 mmol/l. In patients with metabolic acidosis and CKD, oral sodium bicarbonate administration is recommended. The goal of such a treatment is to achieve a plasma or blood bicarbonate concentration equal to or greater than 22 mmol/l. © 2018 The Author(s). Published by S. Karger AG, Basel.

Transition of adolescent and young adult (AYA) patients with childhood-onset chronic kidney diseases (C-CKD) from pediatric to adult renal services has received increasing attention. However, information on transition of Japanese patients with C-CKD is limited. The Transition Medicine Working Group, in collaboration with the Japanese Society for Nephrology, the Japanese Society for Pediatric Nephrology and the Japanese Society of Pediatric Urology, conducted a retrospective cross-sectional study in 2014 on issues concerning the transition of Japanese patients with C-CKD. Few institutions in Japan had transition programs and/or transition coordinators for patients with C-CKD. Refusal to transfer by patients or their families, lack of concern about transition and inability to decide on transfer were common reasons for non-transfer of patients still followed by pediatric renal services. Around 25 % of patients who had ended or interrupted follow-up by pediatric renal services presented to adult renal services because of symptoms associated with C-CKD. Patients with various types of childhood-onset nephrourological diseases were transferred from pediatric to adult renal services. IgA nephropathy, minimal change nephrotic syndrome and congenital anomalies of the kidney and urinary tract were the most frequent primary kidney diseases in adult patients with C-CKD. These survey results indicate the need for introduction of transitional care for Japanese AYA patients with C-CKD. Consensus guidelines for the optimal clinical management of AYA patients with C-CKD are required to ensure the continuity of care from child to adult renal services.

In many developing countries in the South Asian region, screening for chronic diseases in the community has shown a widely varying prevalence. However, certain geographical regions have shown a high prevalence of chronic kidney disease (CKD) of unknown etiology. This predominantly affects the young and middle-aged population with a lower socioeconomic status. Here, we describe the hotspots of CKD of undiagnosed etiology in South Asian countries including the North, Central and Eastern provinces of Sri Lanka and the coastal region of the state of Andhra Pradesh in India. Screening of these populations has revealed cases of CKD in various stages. Race has also been shown to be a factor, with a much lower prevalence of CKD in whites compared to Asians, which could be related to the known influence of ethnicity on CKD development as well as environmental factors. The difference between developed and developing nations is most stark in the realm of healthcare, which translates into CKD hotspots in many regions of South Asian countries. Additionally, the burden of CKD stage G5 remains unknown due to the lack of registry reports, poor access to healthcare and lack of an organized chronic disease management program. The population receiving various forms of renal replacement therapy has dramatically increased in the last decade due to better access to point of care, despite the disproportionate increase in nephrology manpower. In this article we will discuss the nephrology care provided in various countries in South Asia, including India, Bangladesh, Pakistan, Nepal, Bhutan, Sri Lanka and Afghanistan.

It is known that transition, as a shift of care, marks a vulnerable phase in the adolescents' lives with an increased risk for non-adherence and allograft failure. Still, the transition process of adolescents and young adults living with a kidney transplant in Germany is not well defined. The present research aims to assess transition-relevant structures for this group of young people. Special attention is paid to the timing of the process. In an observational study, we visited 21 departments of paediatric nephrology in Germany. Participants were doctors (n=19), nurses (n=14) and psychosocial staff (n=16) who were responsible for transition in the relevant centres. Structural elements were surveyed using a short questionnaire. The experiential viewpoint was collected by interviews which were transcribedverbatim before thematic analysis was performed. This study highlights that professionals working within paediatric nephrology in Germany are well aware of the importance of successful transition. Key elements of transitional care are well understood and mutually agreed on. Nonetheless, implementation within daily routine seems challenging, and the absence of written, structured procedures may hamper successful transition. While professionals aim for an individual timing of transfer based on medical, social, emotional and structural aspects, rigid regulations on transfer age as given by the relevant health authorities add on to the challenge.

Renal anemia is the result of chronic kidney disease (CKD) and deteriorates with disease progression. Anemia may be the first sign of kidney disease. In all patients with anemia and CKD, diagnostic evaluation is required. Prior to diagnosing renal anemia, it is necessary to eliminate the other possible causes. Direct correlation between the concentration of hemoglobin and the stage of renal failure is well known. Early development of anemia is common in diabetic patients. Correction of anemia may slow the progression of CKD. Anemia is an independent risk factor for developing cardiovascular disease in patients with CKD. Treatment of anemia in patients with CKD is based on current guidelines. Recently, the Kidney Disease: Improving Global Outcomes (KDIGO) group has produced comprehensive clinical practice guidelines for the management of anemia in CKD patients and ERBP (European Renal Best Practice) group its position statement and comments on the KDIGO guidelines. The Croatian Society of Nephrology, Dialysis and Transplantation (HDNDT) has already published its own guidelines based on the recommendations and positive experience of European and international professional societies, as well as on own experience. The latest version of Croatian guidelines was published in 2008. Since then, on the basis of research and clinical practice, there have been numerous changes in the modern understanding of the treatment of anemia in CKD. Consequently, HDNDT hereby publishes a review of the recent recommendations of international professional societies, expressing the attitude about treating anemia in CKD as a basis for new guidelines tailored to the present time.

Alport syndrome is a genetic disease that progresses to chronic kidney failure, with X-linked, autosomal dominant or autosomal recessive type of inheritance. Women are generally carriers of the mutation and have a milder form of the disease. During pregnancy, they have an increased risk of impaired kidney function and preeclampsia. A 27-year old woman, gravida 1, para 0, in her 23rd gestational week came to the outpatient unit of the University Clinic of Nephrology for the first time because of slowly progressing proteinuria and Alport syndrome. She was admitted to the gynaecological ward in her 29th gw for proteinuria which increased from 3.8 g/day up to 20 g/day and the serum creatinine increased to 120- 150 micromol/l. She was delivered in the 30th gestational week due to obstetrical indications with a cesarian section and delivered a baby with a birth weight of 880 g. After delivery, proteinuria decreased to 2 g/d within 2 months and an angiotensin-converting enzyme inhibitor (ACEI) was started. Her second pregnancy, after 2 years, had an uneventful course and she delivered a healthy baby weighing 3000 g in the 39th week. Six months after the second delivery, her renal function remained normal and her proteinuria was 2 g/d. Pre-pregnancy counselling and frequent controls during pregnancy are necessary for women with Alport syndrome, as well as regular monitoring after delivery. Recent reports are more in favour of good pregnancy and nephrological outcomes in women with Alport syndrome when renal disease is not advanced.

Hyperoxaluria is a metabolic disorder that can lead to end stage renal disease (ESRD). It can be either inherited or acquired. Primary hyperoxaluria (PHO) is more common and characterized by an excessive production of oxalate leading to recurrent urolithiasis and progressive nephrocalcinosis. Due to the high rate of consanguineous marriage in Jordan this disease is commonly diagnosed in pediatric nephrology clinics. We aimed to demonstrate the clinical pattern and progression to ESRD in pediatric patients with hyperoxaluria at Queen Rania Abdulla Children Hospital. Medical records of all patients followed up in the pediatric nephrology clinic with the diagnosis of PHO during the period between September 2007 and March 2013 were reviewed. There were 70 patients with the diagnosis of PHO, 52.9% were males. The median age at presentation was 3 years ± 3 months with the youngest child being two months old. Diagnosis was made in the first year of life in 15.7% of patients. The most common presenting symptom was hematuria, while 14% of patients were asymptomatic and detected by family screening after the diagnosis of an index case. At the time of initial presentation, 15.7% of patients had ESRD and 25% had impaired renal function. Kidney stones were found in 57% of cases and nephrocalcinosis was found in 37%. High index of suspicion is needed to diagnose PHO in children presenting with kidney stone or unexplained hematuria. Twenty-four hour urine collection for oxalate are required to make the proper diagnosis. Family screening, when appropriate, is indicated for early detection of PHO.

Twitter is the fastest growing social media network. It offers participants the ability to network with other individuals. Medical societies are interested in helping individuals network to boost recruitment, encourage collaboration, and assist in job placement. We hypothesized that the American Society of Nephrology (ASN) successfully used Twitter to create a network between participants and itself to stay connected with its members. Tweets from 3 Twitter networking sessions during Kidney Week 2011 were analyzed for content. These messages were used to create a network between all participants of the networking sessions. The network was analyzed for strength and influence by calculating clustering coefficients (CC) and eigenvector centrality (EC) scores, respectively. Eight moderators and 9 trainees authored 376 Twitter messages. Most tweets by trainees (64%) and moderators (61%) discussed 1 of 3 themes: networking, education, or navigating Kidney Week 2011. A total of 25 online network connections were established during the 3 sessions; 20% were bidirectional. The CC for the network was 0.300. All moderators formed at least 1 connection, but 7 of the 9 trainees failed to make any connections. ASN made 5 unidirectional and 0 bidirectional connections with a low EC of 0.108. ASN was unable to form powerful connections with trainees through Twitter, but medical societies should not be discouraged by the results reported in this investigation. As societies become more familiar with Twitter and understand the mechanisms to develop connections, these societies will have a greater influence within increasingly stronger networks.

A shift to holding individual physicians accountable for patient outcomes, rather than facilities, is intuitively attractive to policy makers and to the public. We were interested in nephrologists' attitudes to, and awareness of, quality metrics and how nephrologists would view a potential switch from the current model of facility-based quality measurement and reporting to publically available reports at the individual physician level. The study was conducted using a web-based survey instrument (Online Appendix 1). The survey was initially pilot tested on a group of 8 nephrologists from across Canada. The survey was then finalized and e-mailed to 330 nephrologists through the Canadian Society of Nephrology (CSN) e-mail distribution list. The 127 respondents were 80% university based, and 33% were medical/dialysis directors. The response rate was 43%. Results demonstrate that 89% of Canadian nephrologists are engaged in efforts to improve the quality of patient care. A minority of those surveyed (29%) had training in quality improvement. They feel accountable for this and would welcome the inclusion of patient-centered metrics of care quality. Support for public reporting as an effective strategy on an individual nephrologist level was 30%. Support for public reporting of individual nephrologist performance was low. The care of nephrology patients will be best served by the continued development of a critical mass of physicians trained in patient safety and quality improvement, by focusing on patient-centered metrics of care delivery, and by validating that all proposed new methods are shown to improve patient care and outcomes.

Children with systemic lupus erythematosus (SLE) generally undergo a pretreatment kidney biopsy. However, some of these patients, especially those with antiphospholipid syndrome (APS), may experience serious coagulopathic complications. We report herein two cases of paediatric SLE with APS in which, despite normal blood test results, the disparate coagulopathic complications of haemorrhage and embolism developed following a kidney biopsy. Case 1 was, an 8-year-old male in whom, primary APS was initially diagnosed. Fourteen months later SLE was diagnosed. Based on a percutaneous kidney biopsy, International Society of Nephrology and the Renal Pathology Society (ISN/RPS) class III-A lupus nephritis was histologically diagnosed. On post-biopsy Day 9, a giant haematoma in the fascia of the left kidney developed and was accompanied by changes in the vital signs. Case 2, a 13-year-old male, initially received the diagnosis of SLE with APS and underwent two courses of pulse methylprednisolone therapy. His coagulation abnormalities improved, and a percutaneous needle kidney biopsy was performed, leading to the histological diagnosis of ISN/RPS class III-A lupus nephritis. Furthermore, thrombotic microangiopathy was also detected in the renal histopathology. On post biopsy Day 6, the patient experienced right leg pain. A contrast CT and lower extremity ultrasonography detected a massive deep vein thrombosis and partial left pulmonary artery thrombosis. A kidney biopsy in children with SLE and APS can cause lethal coagulopathic complications, and the risks to such patients should be weighed carefully before the procedure is performed. © 2017 Asian Pacific Society of Nephrology.

History of Erythropoiesis-Stimulating Agents, the Development of Biosimilars, and the Future of Anemia Treatment in Nephrology.

Exogenous replacement of erythropoietin (EPO) by recombinant human EPO has been considered a standard of care for the treatment of anemia in patients with chronic kidney disease for more than 20 years. Genetically engineered biologic proteins derived from human, animal, or microorganism sources are a major area of growth in modern medical care, accounting for one-third of new drug approvals in the past decade. Despite benefit to patients, the use of biologics comes at a significant cost, representing one of the fastest growing segments of strained healthcare budgets around the world. Biosimilars, or biologic drugs that are designed to be highly similar to approved reference biologic drugs, have been available in Europe for more than 10 years with no unusual or unexpected effects compared to their reference biologics whose patents have expired. Given the success of the biosimilar approval pathway pioneered in Europe, it has served as a global reference for other regulatory authorities to establish and implement biosimilar licensure frameworks, including the United States (US), the largest pharmaceutical market in the world. Given 10 of the top 25 drugs sold in 2014 were biologics, and considering the rising costs of healthcare, biosimilars have the potential to become a significant part of the US market. Key Messages: For the nephrology community, the recent patent expiries for epoetin alfa (Epogen®, Amgen and Procrit®, Johnson & Johnson) have created the opportunity to develop biosimilar EPOs. And while no biosimilar in this therapeutic class is approved in the US, there are proposed biosimilars in development. © 2017 S. Karger AG, Basel.

Receipt of nephrology care prior to end-stage renal disease (ESRD) is a strong predictor of decreased mortality and morbidity, and neighborhood poverty may influence access to care. Our objective was to examine whether neighborhood poverty is associated with lack of pre-ESRD care at dialysis facilities. In a multi-level ecological study using geospatially linked 2007-2010 Dialysis Facility Report and 2006-2010 American Community Survey data, we examined whether high neighborhood poverty (≥20% of households in census tract living below poverty) was associated with dialysis facility-level lack of pre-ESRD care (percentage of patients with no nephrology care prior to dialysis start) in mixed-effects models, adjusting for facility and neighborhood confounders and allowing for neighborhood and regional random effects. Among the 5,184 facilities examined, 1,778 (34.3%) were located in a high-poverty area. Lack of pre-ESRD care was similar in poverty areas (30.8%) and other neighborhoods (29.6%). With adjustment, the absolute increase in percentage of patients at a facility with no pre-ESRD care associated with facility location in a poverty area versus other neighborhood was only 0.08% (95% CI -1.32, 1.47; p = 0.9). Potential effect modification by race and income inequality was detected. Despite previously reported detrimental effects of neighborhood poverty on health, facility neighborhood poverty was not associated with receipt of pre-ESRD care, suggesting no need to target interventions to increase access to pre-ESRD care at facilities in poorer geographic areas.

Few quantitative nephrology-specific simulations assess fellow competency. We describe the development and initial validation of a formative objective structured clinical examination (OSCE) assessing fellow competence in ordering acute dialysis. The three test scenarios were acute continuous renal replacement therapy, chronic dialysis initiation in moderate uremia and acute dialysis in end-stage renal disease-associated hyperkalemia. The test committee included five academic nephrologists and four clinically practicing nephrologists outside of academia. There were 49 test items (58 points). A passing score was 46/58 points. No item had median relevance less than 'important'. The content validity index was 0.91. Ninety-five percent of positive-point items were easy-medium difficulty. Preliminary validation was by 10 board-certified volunteers, not test committee members, a median of 3.5 years from graduation. The mean score was 49 [95% confidence interval (CI) 46-51], κ = 0.68 (95% CI 0.59-0.77), Cronbach's α = 0.84. We subsequently administered the test to 25 fellows. The mean score was 44 (95% CI 43-45); 36% passed the test. Fellows scored significantly less than validators (P < 0.001). Of evidence-based questions, 72% were answered correctly by validators and 54% by fellows (P = 0.018). Fellows and validators scored least well on the acute hyperkalemia question. In self-assessing proficiency, 71% of fellows surveyed agreed or strongly agreed that the OSCE was useful. The OSCE may be used to formatively assess fellow proficiency in three common areas of acute dialysis practice. Further validation studies are in progress.

A Best Practice Guideline about Dialysis fluid purity was developed under the leadership of the Spanish Society of Nephrology in 2004. The second edition revised Guideline considered new evidences and International Standard. The Guideline has established recommendations for standards for preparing dialysate: water, concentrates and hemodialysis proportioning systems. This Guideline is based on the ISO13959, European Pharmacopoeia, the Real Farmacopea Española, the AAMI Standards and Recommended Practices, European Best Practice Guidelines for Haemodialysis, literature reviews, according to their level of evidence, and the opinion of the expert Spanish group. Two levels of quality of water were defined: purified water and high purified water (ultra pure) and for dialysate: ultra pure dialysate. Regular use of ultra pure dialysate is recommended for all type of hemodialysis to prevent and delay the occurrence of complications: inflammation, malnutrition, anaemia and amiloidosis. Water, concentrates and dialysate quality requirements are defined as maximum allowable contaminant levels: chemicals (4.1.2), conductivity, microbial and endotoxins (4.1.1): Monitoring frequency, maintenance and corrective actions were specified. Methods of sampling and analysis were described in appendix (anexos). For microbiological monitoring, R2A medium is recommended, incubated during 7-14 days at a temperature of 17-23°C. The dialysate quality assurance process involves all dialysis staff members and requires strict protocols. The physician in charge of hemodialysis has the ultimate responsibility for dialysate quality. All suggestions and questions about this Guideline are wellcome to www.senefro.org.

The majority of Americans use the Internet daily, if not more often, and many search online for health information to better understand a diagnosis they have been given or to research treatment options. The average American reads at an eighth-grade level. The purpose of this study is to evaluate the readability of online patient education materials on the websites of 14 professional organizations representing the major internal medicine subspecialties. We used ten well-established quantitative readability scales to assess written text from patient education materials published on the websites of the major professional organizations representing the following subspecialty groups: allergy and immunology, cardiology, endocrinology, gastroenterology, geriatrics, hematology, hospice and palliative care, infectious disease, nephrology, oncology, pulmonology and critical care, rheumatology, sleep medicine, and sports medicine. Collectively the 540 articles analyzed were written at an 11th-grade level (SD 1.4 grade levels). The sleep medicine and nephrology websites had the most readable materials, written at an academic grade level of 8.5 ± 1.5 and 9.0 ± 0.2, respectively. Material at the infectious disease site was written at the most difficult level, with average readability corresponding to grades 13.9 ± 0.3. None of the patient education materials we reviewed conformed to the American Medical Association (AMA) and the National Institutes of Health (NIH) guidelines requiring that patient education articles be written at a third- to seventh-grade reading level. If these online resources were rewritten, it is likely that more patients would derive benefit from reading them.

Adult Henoch-Schönlein purpura: Clinical and histopathological predictors of systemic disease and profound renal disease.

A major challenge in the management of adult Henoch-Schönlein purpura is the difficulty in assessing the risk of systemic involvement. There is currently a paucity of data in this area. This study sought to determine specific clinical and histopathological features associated with systemic involvement in adult Henoch-Schönlein purpura. We reviewed the records of 99 adult Henoch-Schönlein purpura patients who presented at the National Skin Centre, Singapore, between January 2008 and May 2015. Renal involvement was found in 56 (56.6%) patients, joint involvement in 21 (21.2%) and gastrointestinal involvement in 13 (13.1%). Age > 30 years was an independent predictor of renal involvement with an adjusted odds ratio of 2.97 (95% confidence interval, 1.08-8.16; P = 0.04). Risk factors for significant renal involvement necessitating nephrology referral were further evaluated: the odds were approximately 60% higher for every 10-year increase in age (95% confidence interval, 1.02-2.57; P = 0.04) and patients with cutaneous bullae and/or necrosis had an almost six times higher risk (95% confidence interval, 1.43-25.00; P = 0.01). This study was limited by its retrospective design. We also lacked long-term data to examine how clinical and histopathological characteristics correlated with long-term disease outcomes. Adult Henoch-Schönlein purpura patients older than 30 years have a threefold increased risk of renal involvement. The risk of profound renal disease necessitating nephrology referral rose significantly with age and the presence of cutaneous bullae and/or necrosis.

Profound disturbances in mineral metabolism are closely linked to the progression of chronic kidney disease. However, increasing clinical and experimental evidence indicates that alterations in phosphate homoeostasis could have an even stronger impact on the heart. The aim of this review is to provide the reader with an update of how alterations in mineral metabolism are related to direct and indirect cardiotoxic effects beyond the nephrology setting. Evidence exists that alterations in mineral metabolism that are related to changes in parathyroid hormone (PTH), vitamin D, and the FGF-23-klotho axis have direct pathological consequences for the heart. Alterations in plasma PTH levels are associated with cardiac dysfunction and detrimental cardiac remodelling. Several clinical studies have associated vitamin D deficiency with the prevalence of cardiovascular disease (CV) and its risk factors. Recent evidences support deleterious direct and nonphosphaturic effects of FGF-23 on the heart as hypertrophy development. In contrast, reduced systemic klotho levels are related to CV damage, at least when advanced age is present. In addition, we discuss how these mineral metabolism molecules can counteract each other in some situations, in the context of failed clinical trials on cardiac protection as is the case of vitamin D supplementation. Among all mineral components, an increase in systemic FGF-23 levels is considered to have the greatest CV impact and risk. However, it is quite possible that many intracellular mechanisms mediated by FGF-23, especially those related to cardiomyocyte function, remain to be discovered. © 2018 Stichting European Society for Clinical Investigation Journal Foundation.

Despite growing need, treatment for end-stage renal disease is limited in low- and middle-income countries due to resource restraints. We describe the development of an educational curriculum and quality improvement program to support continuous ambulatory peritoneal dialysis (CAPD) performed primarily by non-nephrology providers in Sri Lanka. We developed a program of education, outcome tracking, and expert consultation to support providers in Kandy, Sri Lanka. Education included videos and in-person didactics covering core topics in CAPD. Event-tracking sheets recorded root causes and management of infections and hospitalizations. Conferences reviewed clinical cases and overall clinic management. We evaluated the patient census, peritonitis rates, and root causes and management of infections over 1 year. The curriculum was published through the International Society of Nephrology online academy. High provider turnover limited curriculum assessments. The CAPD patient census rose from 63 to 116 during the year. The peritonitis rate declined significantly, from 0.8 episodes per patient-year in the first 6 months to 0.4 in the latter 6 months, though the most common root causes of peritonitis, related to contamination events and hygiene, persisted. The appropriate ascertainment of culture data and prescription of antibiotics also increased. Our project supported the expansion of a CAPD program in a resource-limited setting, while also improving peritonitis outcomes. Ongoing challenges include ensuring a durable educational system for rotating providers, tracking outcomes beyond peritonitis, and formalizing management protocols. Our program can serve as an example of how established dialysis programs can support the burgeoning work of providers in resource-limited setting.

Despite calls for more interprofessional and intraprofessional team-based approaches in healthcare, we lack sufficient understanding of how this happens in the context of patient care teams. This multi-perspective, team-based interview study examined how medical teams negotiated collaborative tensions. From 2011 to 2013, 50 patients across five sites in three Canadian provinces were interviewed about their care experiences and were asked to identify members of their health care teams. Patient-identified team members were subsequently interviewed to form 50 “Team Sampling Units” (TSUs), consisting of 209 interviews with patients, caregivers and healthcare providers. Results are gathered from a focused analysis of 13 TSUs where intraprofessional collaborative tensions involved treating fluid overload, or edema, a common HF symptom. Drawing on actor-network theory (ANT), the analysis focused on intraprofessional collaboration between specialty care teams in cardiology and nephrology. The study found that despite a shared narrative of common purpose between cardiology teams and nephrology teams, fluid management tools and techniques formed sites of collaborative tension. In particular, care activities involved asynchronous clinical interpretations, geographically distributed specialist care, fragmented forms of communication, and uncertainty due to clinical complexity. Teams ‘disentangled’ fluid in order to focus on its physiological function and mobilisation. Teams also used distinct ‘framings’ of fluid management that created perceived collaborative tensions. This study advances collaborative entanglement as a conceptual framework for understanding, teaching, and potentially ameliorating some of the tensions that manifest during intraprofessional care for patients with complex, chronic disease.

There are more than 1.7 million sufferers of end stage kidney disease (ESKD) worldwide and for many a donated kidney provides the only chance of regaining independence from dialysis. Unfortunately, the demand for kidneys for transplantation far exceeds the available supply. It is important, therefore, that we understand the factors that may influence kidney donation rates. While certain socio-demographic factors have been linked to kidney donation rates, few studies have examined the influence of multiple socio-demographic factors on rates of both living and deceased kidney transplantation (KT) and none have examined their comparative effect in large numbers of culturally and socio-politically diverse countries. In this study, we performed univariate and multivariate analyses of the influence of 15 socio-economic factors on both the living donor (LD) and the deceased donor (DD) kidney transplantation rates (KTR) in 53 countries. Our analyses demonstrated that factors such as UN HDI (United Nations Human Development Index), religion, GDP, education, age, healthcare expenditure, presumed consent legislation and existence of a nationally managed organ donation program were associated with higher deceased KTR. In contrast, the only factors associated with living KTR were a highly significant negative association with presumed consent and variable associations with different religions. We suggest that by identifying factors that affect kidney transplantation rates these can be used to develop programs for enhancing donor rates in individual countries where those rates are below the leading countries. © 2013 The Authors.

Lupus nephritis (LN) is a major complication of systemic lupus erythematosus (SLE). Renal involvement is a major determinant of the prognosis of SLE. The histological classification of LN is a key factor in determining the renal survival of patients with LN. Prompt recognition and treatment of renal disease are important, as early response to therapy is correlated with better outcome and renal biopsy plays an important role in achieving this. The objective of this study was to correlate the clinical and laboratory findings with histopathological classes of LN as per the 2003 International Society of Nephrology-Renal Pathology Society (ISN/RPS) classification system. Fifty-six patients with SLE, undergoing a renal biopsy for renal dysfunction were studied. The comparison of data from multiple groups was made by Pearson's Chi-square test and between two groups by independent samples t -test. The values of P < 0.05 were considered statistically significant. Of the 56 cases studied, 51 (91.1%) were females. The most common presenting symptoms were edema, arthralgia, and hypertension. Class IV (55.4%) was the most common class. Thirty-nine (69.6%) cases showed full house immunostaining. Hypertension, hematuria, proteinuria, and tubulo-interstitial disease showed a significant correlation ( P < 0.05) with ISN/RPS classification, 2003. Assessment and management of patients with suspected LN are greatly facilitated through information obtained by renal biopsy. Since renal morphology may predict long-term prognosis, and no clinical or laboratory feature uniformly predicts prognosis, it is important to study the constellation of features in LN for better patient management.

Only a few cases of nosocomial Legionella sp. infection have been reported in children. We report the clinical and epidemiologic data of five nosocomial legionellosis cases that occurred in the Pediatric Nephrology Service between August, 1994, and December, 1998, and the control measures adopted. The Hospital Materno-Infantil Vall d'Hebron, Barcelona, is a 407-bed tertiary care hospital. The pediatric kidney transplant unit has three isolated beds in the same ward within the Pediatric Nephrology Service. Diagnostic workup to establish Legionella pneumophila infection included culture, fluorescent antibody and serologic studies. Macrorestriction analysis of genomic DNA was used as epidemiologic markers of the isolated strains. In May, 1996, a case of L. pneumophila serogroup 6 pneumonia was identified in a 19-year-old youth who had received a kidney transplant 16 days earlier. Retrospective and prospective analysis of legionellosis cases diagnosed at our center up to August, 1994, yielded four additional cases. Four patients had had a kidney transplant and were receiving immunosuppressive therapy, and the fifth had been diagnosed with systemic lupus erythematosus with renal involvement. L. pneumophila serogroup 6 was isolated in bronchial secretions in four cases; in the fifth patient the diagnosis was made by serology. L. pneumophila serogroup 6 was isolated from potable water of the hospital. Molecular epidemiologic methods revealed the identity of the environmental and clinical isolates. Showering was implicated as the most feasible means of exposure to contaminated water. Nosocomial legionellosis, albeit rare in children, should be considered in the differential diagnosis of pneumonias, particularly in immunosuppressed children, because the fatality rate may be high without early diagnosis and treatment.

Fifty to eighty percent of patients suffering from chronic kidney disease (CKD) experience a form of sexual dysfunction (SD), even after renal transplantation. Despite this, inquiring about SD is often not included in the daily practice of renal care providers. This paper explores the perspectives of renal social workers regarding sexual care for patients and evaluates their practice, attitude towards responsibility and knowledge of SD. A cross-sectional study was conducted using a 41-item online survey. Seventy-nine members of the Dutch Federation of Social Workers Nephrology. It was revealed that 60% of respondents discussed SD with a fifth of their patients. Frequency of discussion was associated with experience (p = 0.049), knowledge (p = 0.001), supplementary education (p = 0.006), and the availability of protocols on sexual care (p = 0.007). Main barriers towards discussing SD consisted of 'culture and religion' (51.9%), 'language and ethnicity' (49.4%), and 'presence of a third person' (45.6%). Sufficient knowledge of SD was present in 28% of respondents. The responsibility for discussion was 96% nephrologists and 81% social workers. This study provides evidence that a part of Dutch nephrology social workers do not provide sexual care regularly, due to insufficient experience and sexual knowledge, absence of privacy and protocols and barriers based on cultural diversity. According to the respondents the responsibility for this aspect of care should be multidisciplinary. Recommendations include a need for further education on the topic, private opportunities to discuss SD and multidisciplinary guidelines on sexual care. © 2017 European Dialysis and Transplant Nurses Association/European Renal Care Association.

Psychological factors associated with successful outcomes in home haemodialysis.

Performing haemodialysis therapy at home has been associated with improved survival for end-stage kidney disease patients and can generally be delivered at a lower cost to the healthcare system when compared with centre and satellite unit dialysis. However, only a minority of dialysis dependent end-stage kidney disease patients successfully sustain haemodialysis at home. Current practice for determining dialysis treatment modality and location takes into account medical suitability and social situation, but infrequently formally examines the contribution of psychological factors. This study explores demographic, health, and psychological factors that may predict patients' ability to sustain home haemodialysis. One hundred and thirteen successful and unsuccessful home haemodialysis users were recruited to the study, and 55 responded to self-report measures. Demographic (age, gender, education level, carer support), health (comorbidities, diabetes, psychiatric condition) and psychological (locus of control beliefs, coping styles) information was used as predictor variables for the participants' time maintaining home therapy (Home Time). In a three-step regression, the model explained 32% of variance in Home Time. Coping styles significantly contributed 16% of the variance in Home Time after accounting for other variables. Adaptive Coping was significantly correlated with the length of time sustaining home therapy. Adaptive coping strategies are associated with improved ability to sustain home haemodialysis therapy. Evidence-based psychological approaches can help patients develop more adaptive coping strategies. More research is needed to assess whether instituting these psychological interventions will assist patients to adopt and sustain dialysis therapies which require increased patient self-management. © 2013 Metro South Hospital and Health Services, Queensland, Australia.

Autosomal dominant polycystic kidney disease (ADPKD) is characterized by abnormal enhanced cell proliferation and fluid secretion, which are triggered by increased levels of cyclic adenosine monophosphate (cAMP). Cebotaru et al. showed that a HDAC6 inhibitor reduced the cAMP level and inhibited cyst formation in Pkd1 knockout mice, which may become a new potential therapeutic agent for ADPKD. This study also raised several intriguing questions that might advance our understanding of the molecular pathogenesis of ADPKD. Copyright © 2016 International Society of Nephrology.

Complement activation probably contributes to glomerular inflammation and damage in IgA nephropathy. In this issue, 2 groups report that levels of factor H-related protein 1 are elevated in patients with IgA nephropathy and correlate with disease progression. These studies provide new evidence that the complement cascade is important to the pathogenesis of this disease. These results also suggest that factor H-related protein 1 levels may be useful for identifying those patients at high risk of disease progression.

Legalizing kidney market: ethics considerations. The paper by E A Friedman and A L Friedman, advocating suitable kidney sale legislation, recently published in Kidney International, has aroused some controversy among the Italian Society of Nephrology Mailing List members (ML-SIN). A previous article reviewed the main issues and summarized Italian nephrologists' opinions. Generally speaking, ML-SIN participants were critical towards this proposal; the most widespread opinion was that trade of organs for transplant purposes is unethical and that Friedman's legislative suggestion is unlikely to succeed in Italy. To complete discussion, we report also the opinion of an authoritative Ethics expert.

An association between hypothyroidism and renal impairment has rarely been reported in the literature. We describe a case of hypothyroidism that was associated with otherwise unexplained acute kidney impairment, which was reversed with treatment. A 21-year-old female patient presented to her family physician with myalgia, and preliminary investigations revealed an elevated level of creatine kinase and poor renal function. Primary hypothyroidism was diagnosed and no other apparent etiology for renal failure could be identified despite extensive investigations by the Nephrology Department. Notably, the patient's renal impairment showed prompt resolution following thyroid hormone replacement.

Single-cell RNA-sequence (RNA-seq) is a widely used tool to study biological questions in single cells. The discussed study identified 92 genes being predominantly expressed in podocytes based on a 5-fold higher expression compared with endothelial and mesangial cells. In addition to technical pitfalls, the question that is discussed in this commentary is whether results of a single-cell RNAseq study are able to deliver expression data that truly characterize a podocyte.

The life of Lord Moynihan is briefly reviewed. Incidence of stones in Peninsular Malaysia appears to show the same trend as in other industrialised countries. Management of urinary calculi both prior to and after the introduction of ESWL in a personal series is discussed. More than 90% of urinary stones are now treated by ESWL threatening the place of surgery in Urology. The pattern of incorporating renal transplantation into the urological training programme as practised in the Institute of Urology and Nephrology in Malaysia is suggested as a way to assure a place for surgery in Urology.

Histone deacetylases have been reported to protect against renal tubular damage in several animal models of acute renal injury, including cisplatin nephrotoxicity. However, the mechanism involved is not well defined. In this study, Ranganathan et al. identify activated microglia/macrophage WAP domain protein as the novel mediator of histone deacetylase inhibitor-mediated renal protection in a murine model of cisplatin nephrotoxicity. Activated microglia/macrophage WAP-mediated renal protection is associated with suppression of inflammation and renal epithelial cell apoptosis. Copyright © 2016 International Society of Nephrology.

Certain medications have been associated with drug-induced acute interstitial nephritis (AIN), but few prospective studies have been published. This prospective observational study aims to record and assess incidents of drug-induced AIN observed over a period of one year in nephrology units in France. The goal is to determine which medications are involved in AIN and to expound the clinical and biological presentation, management, and evolution of AIN. Between April 2012 and April 2013, drug-associated cases of AIN were prospectively recorded in 24 patients registered in 11 nephrology units that belong to the Société de Néphrologie de l'Ouest (SNO). Data sheets, including suspected and concomitant drug(s), kidney function assessment, biological disturbances, clinical signs, histological data, management, and evolution, were collected by the Rennes Regional Pharmacovigilance Center and recorded in the French pharmacovigilance database. In order, the most frequently involved medications in the AIN cases were: vitamin K antagonists (33.3% of the cases, almost exclusively fluindione), antibiotics (20.8% of cases) non-steroidal anti-inflammatory drugs (20.8% of cases), and proton pump inhibitors (16.7% of cases). The mean delay of onset to AIN was 8.3 weeks. At the time of diagnosis, mean serum creatinine was 366 μM, higher for vitamin K antagonists (VKAs), except in the case of warfarin. During the course of an AIN event, 70% of patients had complete blood count and/or urine analysis abnormalities, 55% had clinical signs of systemic hypersensitivity, and 13% of patients had hepatic disorders. Renal biopsies were performed in 54% of patients; however, only 37% of patients requiring therapeutic anticoagulation underwent a biopsy. Suspected drugs were discontinued in all patients and the majority was treated with oral corticosteroids. Renal function often continued to be impaired after an AIN event. At baseline, 25% of patients had chronic kidney disease (CKD); after an AIN event, 67% of patients were noted to have CKD. Physicians need to be aware of the possibility of drug-induced acute interstitial nephritis as a common cause of acute kidney injury (AKI). This study supports increased vigilance when prescribing three therapeutic classes frequently associated with AIN: antibiotics, NSAIDs and PPIs (especially in instances of polypharmacy), which were associated with two thirds of the AIN cases in this study. Fluindione, an oral anticoagulant exclusively marketed in Luxembourg and France where it constitutes the vast majority of VKA prescriptions, was associated with one third of the AIN cases alone, making it a common possible culprit of drug-induced AIN, warranting particular attention.

2016-12-01

Despite 10 years of post-marketing safety monitoring of the phosphate binder lanthanum carbonate, concerns about aluminium-like accumulation and toxicity persist. Here, we present a concise overview of the safety profile of lanthanum carbonate and interim results from a 5-year observational database study (SPD405-404; ClinicalTrials.gov identifier: NCT00567723). The pharmacokinetic paradigms of lanthanum and aluminium are different in that lanthanum is minimally absorbed and eliminated via the hepatobiliary pathway, whereas aluminium shows appreciable absorption and is eliminated by the kidneys. Randomised prospective studies of paired bone biopsies revealed no evidence of accumulation or toxicity in patients treated with lanthanum carbonate. Patients treated with lanthanum carbonate for up to 6 years showed no clinically relevant changes in liver enzyme or bilirubin levels. Lanthanum does not cross the intact blood-brain barrier. The most common adverse effects are mild/moderate nausea, diarrhoea and flatulence. An interim Kaplan-Meier analysis of SPD405-404 data from the United States Renal Data System revealed that the median 5-year survival was 51.6 months (95% CI: 49.1, 54.2) in patients who received lanthanum carbonate (test group), 48.9 months (95% CI: 47.3, 50.5) in patients treated with other phosphate binders (concomitant therapy control group) and 40.3 months (95% CI: 38.9, 41.5) in patients before the availability of lanthanum carbonate (historical control group). Bone fracture rates were 5.9%, 6.7% and 6.4%, respectively. After more than 850 000 person-years of worldwide patient exposure, there is no evidence that lanthanum carbonate is associated with adverse safety outcomes in patients with end-stage renal disease. © 2016 Shire Development LLC.

2018-01-01

Chronic Kidney Disease (CKD) is a major public health problem and is increasingly being recognized as an important driver of costs in all health care systems. The diversity of outcomes for people living with CKD is in part due to variability in biology, access to care, environmental factors, and health care system differences. The International Society of Nephrology (ISN), working in collaboration with its partners, has evolved into a philanthropic organization, from a traditional medical society, committed to a vision that sees "a future where all people have access to sustainable kidney health". A set of activities, including a Global Kidney Health Summit, the Global Kidney Health Atlas, and a Global Kidney Health Policy Forum, which has formed the basis of a multi-stakeholder engagement process, building on a solid base of ISN programs and educational activities, is described. Through building awareness and increasing capacity to conduct research, the international community will build a more solid foundation on which to advocate for sustainable, ethical solutions to the problem of kidney disease throughout the world. The ISN aims to improve kidney health worldwide through a variety of diverse activities addressing education, advocacy, and research. Collaboration with partners within and outside the medical community is key in achieving this goal. Key Messages: Kidney disease is an important public health problem and is driven by genetic, environmental, and socioeconomic factors. Through active collaboration with diverse partners, the international community is striving for sustainable kidney health and aims to achieve this through coordinated work in a variety of spheres. © 2018 The Author(s) Published by S.

Creation of a vascular access (VA) for haemodialysis is a surgical procedure which comprises a failure rate related to the quality of the vessels and the operator's experience. The authors report the first 2 years of a young urologist's experience with this procedure in a local hospital in collaboration with the nephrology team. Patients undergoing creation of VA were divided into 2 chronological groups. The patient's age and gender, the cause of renal failure, the presence of diabetes, clinical examination of the upper limb, preoperative assessment of upper limb vessels, the type of anaesthesia, the operating time and the start of dialysis after the operation, as well as the functional results of the VA at 6 months were studied. Results concerning the patients of the first period were discussed by the operator and the nephrology team. During the first 9 months, 28 patients were operated, corresponding to 36 operations including 32 direct fistulas. Over the following 15 months, 61 patients were operated, with the creation of 63 VAs, including 55 direct fistulas. The failure rate (thrombosis or non-functioning VA) decreased from 32.1% to 11.1% (p=0.07), while the 2 groups were globally comparable. Evaluation of a new surgical procedure shows a number of failures, as for all learning curves. However, it helps to improve the results. Collaboration with nephrologists must comprise a discussion allowing the acceptance of certain failures, as they reflect compliance with a strategy of preservation of the vascular capital and a rational attempt to avoid a non-essential proximal access or bypass graft. The support of a motivated radiology team (preoperative assessment and management of complications) and the assistance of a more experienced operator are essential.

Low protein diets for chronic kidney disease in non diabetic adults.

For more than fifty years, low protein diets have been proposed to patients with kidney failure. However, the effects of these diets in preventing severe kidney failure and the need for maintenance dialysis have not been resolved. To determine the efficacy of low protein diets in delaying the need to start maintenance dialysis. Cochrane Renal Group studies register, the Cochrane Central Register of Controlled studies, MEDLINE, and EMBASE. Congress abstracts (American Society of Nephrology since 1990, European Dialysis Transplant Association since 1985, International Society of Nephrology since 1987). Direct contacts with investigators. Randomised studies comparing two different levels of protein intake in adult patients suffering from moderate to severe kidney failure, followed for at least one year. Two authors independently selected studies and extracted data. Statistical analyses were performed using the random effects model and the results expressed as risk ratio (RR) for dichotomous outcomes with 95% confidence intervals (CI). Collection of the number of "renal deaths" defined as the need for starting dialysis, the death of a patient or a kidney transplant during the study. Ten studies were identified from over 40 studies. A total of 2000 patients were analysed, 1002 had received reduced protein intake and 998 a higher protein intake. There were 281 renal deaths recorded, 113 in the low protein diet and 168 in the higher protein diet group (RR 0.68, 95% CI 0.55 to 0.84, P = 0.0002). To avoid one renal death, 2 to 56 patients need to be treated with a low protein diet during one year. Reducing protein intake in patients with chronic kidney disease reduces the occurrence of renal death by 32% as compared with higher or unrestricted protein intake. The optimal level of protein intake cannot be confirmed from these studies.

Chronic kidney disease (CKD) is increasingly recognized as a global health problem. The conditions leading to CKD, the health impact of CKD and the prognosis differ markedly between affected individuals. In particular, renal failure and cardiovascular mortality are competing risks for CKD patients. Opportunities for targeted intervention are very limited so far and require an improved understanding of the natural course of CKD, of the risk factors associated with various clinical end points and co-morbidities as well as of the underlying pathogenic mechanisms. The German Chronic Kidney Disease (GCKD) study is a prospective observational national cohort study. It aims to enrol a total of 5000 patients with CKD of various aetiologies, who are under nephrological care, and to follow them for up to 10 years. At the time of enrolment, male and female patients have an estimated glomerular filtration rate (eGFR) of 30-60 mL/min×1.73 m2 or overt proteinuria in the presence of an eGFR>60 mL/min×1.73 m2. Standardized collection of biomaterials, including DNA, serum, plasma and urine will allow identification and validation of biomarkers associated with CKD, CKD progression and related complications using hypothesis-driven and hypothesis-free approaches. Patient recruitment and follow-up is organized through a network of academic nephrology centres collaborating with practising nephrologists throughout the country. The GCKD study will establish one of the largest cohorts to date of CKD patients not requiring renal replacement therapy. Similarities in its design with other observational CKD studies, including cohorts that have already been established in the USA and Japan, will allow comparative and joint analyses to identify important ethnic and geographic differences and to enhance opportunities for identification of relevant risk factors and markers.

Medical knowledge encompasses both conceptual (facts or "what" information) and procedural knowledge ("how" and "why" information). Conceptual knowledge is known to be an essential prerequisite for clinical problem solving. Primarily, medical students learn from textbooks and often struggle with the process of applying their conceptual knowledge to clinical problems. Recent studies address the question of how to foster the acquisition of procedural knowledge and its application in medical education. However, little is known about the factors which predict performance in procedural knowledge tasks. Which additional factors of the learner predict performance in procedural knowledge? Domain specific conceptual knowledge (facts) in clinical nephrology was provided to 80 medical students (3rd to 5th year) using electronic flashcards in a laboratory setting. Learner characteristics were obtained by questionnaires. Procedural knowledge in clinical nephrology was assessed by key feature problems (KFP) and problem solving tasks (PST) reflecting strategic and conditional knowledge, respectively. Results in procedural knowledge tests (KFP and PST) correlated significantly with each other. In univariate analysis, performance in procedural knowledge (sum of KFP+PST) was significantly correlated with the results in (1) the conceptual knowledge test (CKT), (2) the intended future career as hospital based doctor, (3) the duration of clinical clerkships, and (4) the results in the written German National Medical Examination Part I on preclinical subjects (NME-I). After multiple regression analysis only clinical clerkship experience and NME-I performance remained independent influencing factors. Performance in procedural knowledge tests seems independent from the degree of domain specific conceptual knowledge above a certain level. Procedural knowledge may be fostered by clinical experience. More attention should be paid to the interplay of individual clinical clerkship experiences and structured teaching of procedural knowledge and its assessment in medical education curricula.

ABSTRACT Purpose: The Journal Impact Factor (JIF) is an index used to compare a journal's quality among academic journals and it is commonly used as a proxy for journal quality. We sought to examine the JIF in order to elucidate the main predictors of the index while generating awareness among scientific community regarding need to modify the index calculation in the attempt to turn it more accurate. Materials and Methods: Under the Urology and Nephrology category in the Journal Citations Report Website, the top 17 Journals by JIF in 2011 were chosen for the study. All manuscripts’ abstracts published from 2009-2010 were reviewed; each article was categorized based on its research design (Retrospective, Review, etc). T and correlation tests were performed for categorical and continuous variables respectively. The JIF was the dependent variable. All variables were then included in a multivariate model. Results: 23,012 articles from seventeen journals were evaluated with a median of 1,048 (range=78-6,342) articles per journal. Journals with a society affiliation were associated with a higher JIF (p=0.05). Self-citations (rho=0.57, p=0.02), citations for citable articles (rho=0.73, p=0.001), citations to non-citable articles (rho=0.65, p=0.0046), and retrospective studies (rho=-0.51, p=0.03) showed a strong correlation. Slight modifications to include the non-citable articles in the denominator yield drastic changes in the JIF and the ranking of the journals. Conclusion: The JIF appears to be closely associated with the number of citable articles published. A change in the formula for calculating JIF to include all types of published articles in the denominator would result in a more accurate representation. PMID:26742962

BACKGROUND: Diabetes and nephropathy are important challenges during pregnancy, increasingly encountered because of the advances in maternal-fetal care. AIM: To evaluate the maternal and fetal outcomes recorded in "severe" diabetic nephropathy in type 1 diabetic patients referred to nephrological healtcare. METHODS: The study was performed in an outpatient unit dedicated to kidney diseases in pregnancy (with joint nephrological and obstetric follow-up and strict cooperation with the diabetes unit). 383 pregnancies were referred to the outpatient unit in 2000-2012, 14 of which were complicated by type 1 diabetes. The report includes 12 deliveries, including 2 pregnancies in 1 patient; one twin pregnancy; 2 spontaneous abortions were not included. All cases had long-standing type 1 diabetes (median of 21 (15-31) years), relatively high median age (35 (29-40) years) and end-organ damage (all patients presented laser-treated retinopathy and half of them clinical neuropathy). Median glomerular filtration rate (GFR) at referral was 67 ml/min (48-122.6), proteinuria was 1.6 g/day (0.1-6.3 g/day). RESULTS: Proteinuria steeply increased in 11/12 patients, reaching the nephrotic range in nine (6 above 5 g/day). One patient increased by 2 chronic kidney disease (CKD) stages. Support therapy included blood pressure and diabetes control, bed rest, and moderate protein restriction. All children were preterm (7 early preterm); early spontaneous labor occurred in 4/12 patients. All singletons were appropriate for gestational age and developed normally after birth. The male twin child died 6 days after birth (after surgery for great vessel transposition). CONCLUSIONS: Diabetic patients with severe diabetic nephropathy are still present a considerable challenge. Therefore, further investigations are required, particularly on proteinuria management and the occurrence of spontaneous labor. PMID:24172700

The number of patients starting renal replacement therapy (RRT) is increasing in England, as it is worldwide. Improvements in the management of chronic kidney disease (CKD) across communities to alter this trend are a public health priority. We have prospectively studied changes in the incidence and modality of treatment for end-stage renal disease following the introduction of a CKD management programme in the West Midlands region of England. Nephrology service to approximately 700 000 adult population of mixed ethnicity in urban and suburban areas, many with social deprivation. The programme was introduced in stages between 2003 and 2006 and comprised primary care education and financial incentives, personal clinical reports written directly to patients following every consultation, routine laboratory estimated glomerular filtration rate (eGFR) reporting, eGFR graph surveillance to identify and monitor patients at risk, multidisciplinary pre-RRT care and conservative care. Prevalent patients: 10 552 with CKD and 8509 without CKD with diabetes. access to nephrology care, trends in RRT incidence and starting modality, place of death without RRT. Incident count was adjusted for changes in the local adult population recorded in national censuses. Ninety-one per cent of patients aged ≥75 years with incident CKD stage 5 were known to a nephrologist. The population-adjusted incident RRT rate peaked in 2005 and then declined; the proportion starting with transplant, peritoneal dialysis or haemodialysis by arterio-venous fistula increased to 63% by 2012 (P = 0.001 versus 2005). Fifty-two per cent of patients receiving planned conservative care without dialysis died out of hospital. Following the introduction of a community-wide systematic CKD management programme, the population-adjusted incidence of RRT reduced, modality of initiation of RRT improved and a majority of patients receiving planned conservative care without dialysis died out of hospital.

Epidemiology of acute kidney injury in children worldwide, including developing countries.

In this review we summarize the world-wide epidemiology of acute kidney injury (AKI) in children with special emphasis on low-income countries, notably those of the sub-Saharan continent. We discuss definitions and classification systems used in pediatric AKI literature. At present, despite some shortcomings, traditional Pediatric Risk Injury Failure Loss and End Stage Kidney Disease (pRIFLE) and Kidney Disease Improving Global Outcomes (KDIGO) systems are the most clinically useful. Alternative definitions, such as monitoring serum cystatin or novel urinary biomarkers, including cell cycle inhibitors, require more long-term studies in heterogenous pediatric AKI populations before they can be recommended in routine clinical practice. A potentially interesting future application of some novel biomarkers could be incorporation into the "renal angina index", a concept recently introduced in pediatric nephrology. The most reliable epidemiological data on AKI in children come from high-outcome countries and are frequently focused on critically ill pediatric intensive care unit populations. In these patients AKI is often secondary to other systemic illnesses or their treatment. Based on a recent literature search performed within the framework of the "AKI 0by25" project of the International Society of Nephrology, we discuss the scarce and often inaccurate data on AKI epidemiology in low-income countries, notably those on the African continent. The last section reflects on some of the many barriers to improvement of overall health care in low-income populations. Although preventive strategies for AKI in low-income countries should essentially be the same as those in high-income countries, we believe any intervention for earlier detection and better treatment of AKI must address all health determinants, including educational, cultural, socio-economic and environmental factors, specific for these deprived areas.

Vegetarian diets have long been thought of as beneficial to health. However, vegetarian diets are often low in protein, which is contradictory to the high protein diet guideline for uraemia patients. The purpose of the study was to investigate the impact of a vegetarian diet on the nutritional status of haemodialysis (HD) patients. Patients on chronic HD for over 6 months were included in the study. The normalized protein catabolic rate (nPCR) was used to reflect daily protein intake. Biochemical markers of nutrition, anthropometric parameters, subjective global assessment (SGA) and functional activity of daily living were assessed to evaluate the nutritional status of vegetarians on chronic HD. Nineteen out of 318 HD patients were vegetarians. The nPCR was lower in the vegetarian group (1.20 ± 0.24 vs 1.10 ± 0.29 g/kg per day, non-Veg vs Veg, P < 0.05). The serum albumin and prealbumin were similar in vegetarian and non-vegetarian HD patients. The body mass index (BMI) and mid-arm muscular circumference (MAMC) were lower in vegetarian patients (P < 0.05). The haematocrit of vegetarians can be maintained at a level similar to that of non-vegetarian patients but erythropoietin doses needed were higher in vegetarian patients (P < 0.05). The muscle strength evaluated by the hand-grip test, SGA and activities of daily living were similar in vegetarians and non-vegetarians. The present study revealed that HD patients on vegetarian diets might have a smaller BMI, but SGA and function of daily activities were similar to those of the non-vegetarians. The haematocrit of vegetarians can be maintained with a higher erythropoietin dose. © 2011 The Authors. Nephrology © 2011 Asian Pacific Society of Nephrology.

Background: Chronic kidney disease (CKD) is increasing worldwide and can lead to end-stage renal disease (ESRD). Objectives: Because few patients with ESRD in the Republic of Guinea have access to haemodialysis, we retrospectively evaluated the prevalence of CKD, ESRD and access to supportive therapies. Patients and Methods: 579 CKD patients (304 males; mean age: 44 ± 16 years) were admitted into Conakry nephrology department, the only centre in the Republic of Guinea, between 2009 and 2013. Most patients (63%) resided within Conakry (the capital), 12.5% came from lower Guinea, 11.7% from middle Guinea, 7.9% from upper Guinea and 4.8% from forest Guinea. Results: Reasons for referral were increased serum creatinine (49.5%), hypertension (27%) and diffuse edema (17%). Also, 11% were diabetic, 12.5% were smokers, 17% were HIV-positive, 8.3% were HBV-positive and 15% were HCV-positive. The most frequent symptom at admission was nausea/vomiting (56%). Upon admission, 70.5% of patients already had ESRD. Although no kidney biopsies were performed it was assumed that 34% and 27% of patients had vascular nephropathy and chronic glomerulonephritis, respectively. Of the 385 ESRD patients, only 140 (36.3%) had access to haemodialysis (two sessions/week, 4 hours each). Most patients that received haemodialysis resided within the Conakry region (P < 0.0001). There were significant associations between mortality and (i) terminal stage of CKD (P = 0.0005), (ii) vascular nephropathy (P = 0.002), and (iii) nephropathies of unknown origin (P = 0.0001). Conclusions: A fourfold increase in haemodialysis machines is needed in Conakry, plus four new nephrology/haemodialysis centres within the Republic of Guinea, each holding ≥30 haemodialysis machines.

Chronic renal failure is a global public health problem. In developed countries, this disease occurs mainly in the elderly, but in Africa it rather affects active young subjects. This disease need for expensive treatments in a low income country, because of its costs. Our aim is to describe the epidemiology of new cases of chronic renal failure in Madagascar. This is a retrospective, descriptive study of 239 patients with chronic renal failure over a 3 year period, starting from 1 January 2007 to 31 December 2009, in the Department of Internal Medicine and Nephrology at University Hospital of Antananarivo. The incidence was 8.51% among patients hospitalized in the Department. The average age of patients was 45.4 years with extremes of 16 and 82 years and a sex ratio 1,46. The main antecedent was arterial hypertension (59.8%). Chronic renal failure was terminal in 75.31% of the cases (n=180). The causes of chronic renal failure were dominated by chronic glomerulonephritis (40.1%), nephroangiosclerosis (35.5%). Hemodialysis was performed in 3 patients (1.26%), no patient was scheduled for a renal transplantation. Mortality rate in the Department was 28.87%. Chronic renal failure is a debilitating disease with a dreadful prognosis which affects young patients in Madagascar. Its treatment remains inaccessible to the majority of patients. The focus must be mainly on prevention, especially on early effective management of infections, arterial hypertension and diabetes to reduce its negative impacts on the community and public health. The project on renal transplantation: living donor, effective and less expensive treatment compared to hemodialysis could also be a good solution for these Malagasy young subjects.

The improvement of technology has increased noise levels in hospital Wards to higher than international standard levels (35-45 dB). Higher noise levels than the maximum level result in patient's instability and dissatisfaction. Moreover, it will have serious negative effects on the staff's health and the quality of their services. The purpose of this survey is to analyze the level of noise in intensive care units and emergency wards of the Imam Reza Teaching Hospital, Mashhad. This research was carried out in November 2009 during morning shifts between 7:30 to 12:00. Noise levels were measured 10 times at 30-minute intervals in the nursing stations of 10 wards of the emergency, the intensive care units, and the Nephrology and Kidney Transplant Departments of Imam Reza University Hospital, Mashhad. The noise level in the nursing stations was tested for both the maximum level (Lmax) and the equalizing level (Leq). The research was based on the comparison of equalizing levels (Leq) because maximum levels were unstable. In our survey the average level (Leq) in all wards was much higher than the standard level. The maximum level (Lmax) in most wards was 85-86 dB and just in one measurement in the Internal ICU reached 94 dB. The average level of Leq in all wards was 60.2 dB. In emergency units, it was 62.2 dB, but it was not time related. The highest average level (Leq) was measured at 11:30 AM and the peak was measured in the Nephrology nursing station. The average levels of noise in intensive care units and also emergency wards were more than the standard levels and as it is known these wards have vital roles in treatment procedures, so more attention is needed in this area.

Although infrequent, kidney disease is a potentially serious co-morbidity among human immunodeficiency virus (HIV)-infected patients. The spectrum of renal impairment is very wide from clinically insignificant to end stage renal disease and often requires nephrologist's consultation. Therefore, we established combined renal and HIV care in the HIV Out-Patient Clinic in Warsaw. Medical records of patients consulted by nephrologist from March 2014 to March 2015 were included in analyses. Patients changing medication without consulting the physician or persistently not coming for follow-up visits were defined as non-compliant. In statistical analyses, non-parametric tests and logistic regression models were used as appropriate. In total, 100 patients were consulted by a nephrologist during the study period. All patients were white Europeans, 88 (88%) male, 42 (42%) infected through men having sex with men and 16 (16%) through intravenous drug users. Fifteen (15%) patients had hepatitis C virus (HCV) infections and 11 (11%) confirmed with positive HCV RNA. The most common reasons for referral were proteinuria and increased serum creatinine. In 6 out of 31 patients (19.3% of those referred for increased creatinine level) elevated serum creatinine was due to illegal substances or diet supplements use. Fifty-seven (57%) of patients were non-compliant. In univariate logistic regression models, all tested factors were non-significant. In most cases, patients were referred to nephrologist due to possible link between laboratory abnormalities and antiretroviral treatment. In one out of five cases, elevated creatinine level was linked with substance/dietary abuse. Poor compliance is an important problem in integrated nephrological care, however we were not able to identify any factors associated with non-compliance.

Search filters have been developed and demonstrated for better information access to the immense and ever-growing body of publications in the biomedical domain. However, to date the number of filters remains quite limited because the current filter development methods require significant human efforts in manual document review and filter term selection. In this regard, we aim to investigate automatic methods for generating search filters. We present an automated method to develop topic-specific filters on the basis of users' search logs in PubMed. Specifically, for a given topic, we first detect its relevant user queries and then include their corresponding clicked articles to serve as the topic-relevant document set accordingly. Next, we statistically identify informative terms that best represent the topic-relevant document set using a background set composed of topic irrelevant articles. Lastly, the selected representative terms are combined with Boolean operators and evaluated on benchmark datasets to derive the final filter with the best performance. We applied our method to develop filters for four clinical topics: nephrology, diabetes, pregnancy, and depression. For the nephrology filter, our method obtained performance comparable to the state of the art (sensitivity of 91.3%, specificity of 98.7%, precision of 94.6%, and accuracy of 97.2%). Similarly, high-performing results (over 90% in all measures) were obtained for the other three search filters. Based on PubMed click-through data, we successfully developed a high-performance method for generating topic-specific search filters that is significantly more efficient than existing manual methods. All data sets (topic-relevant and irrelevant document sets) used in this study and a demonstration system are publicly available at http://www.ncbi.nlm.nih.gov/CBBresearch/Lu/downloads/CQ_filter/

Abstract Background Few quantitative nephrology-specific simulations assess fellow competency. We describe the development and initial validation of a formative objective structured clinical examination (OSCE) assessing fellow competence in ordering acute dialysis. Methods The three test scenarios were acute continuous renal replacement therapy, chronic dialysis initiation in moderate uremia and acute dialysis in end-stage renal disease-associated hyperkalemia. The test committee included five academic nephrologists and four clinically practicing nephrologists outside of academia. There were 49 test items (58 points). A passing score was 46/58 points. No item had median relevance less than ‘important’. The content validity index was 0.91. Ninety-five percent of positive-point items were easy–medium difficulty. Preliminary validation was by 10 board-certified volunteers, not test committee members, a median of 3.5 years from graduation. The mean score was 49 [95% confidence interval (CI) 46–51], κ = 0.68 (95% CI 0.59–0.77), Cronbach’s α = 0.84. Results We subsequently administered the test to 25 fellows. The mean score was 44 (95% CI 43–45); 36% passed the test. Fellows scored significantly less than validators (P < 0.001). Of evidence-based questions, 72% were answered correctly by validators and 54% by fellows (P = 0.018). Fellows and validators scored least well on the acute hyperkalemia question. In self-assessing proficiency, 71% of fellows surveyed agreed or strongly agreed that the OSCE was useful. Conclusions The OSCE may be used to formatively assess fellow proficiency in three common areas of acute dialysis practice. Further validation studies are in progress. PMID:29644053

Complicated pregnancies in inherited distal renal tubular acidosis: importance of acid-base balance.

PubMed

2017-06-01

Inherited distal renal tubular acidosis (dRTA) is caused by impaired urinary acid excretion resulting in hyperchloremic metabolic acidosis. Although the glomerular filtration rate (GFR) is usually preserved, and hypertension and overt proteinuria are absent, it has to be considered that patients with dRTA also suffer from chronic kidney disease (CKD) with an increased risk for adverse pregnancy-related outcomes. Typical complications of dRTA include severe hypokalemia leading to cardiac arrhythmias and paralysis, nephrolithiasis and nephrocalcinosis. Several physiologic changes occur in normal pregnancy including alterations in acid-base and electrolyte homeostasis as well as in GFR. However, data on pregnancy in women with inherited dRTA are scarce. We report the course of pregnancy in three women with hereditary dRTA. Complications observed were severe metabolic acidosis, profound hypokalemia aggravated by hyperemesis gravidarum, recurrent urinary tract infection (UTI) and ureteric obstruction leading to renal failure. However, the outcome of all five pregnancies (1 pregnancy each for mothers n. 1 and 2; 3 pregnancies for mother n. 3) was excellent due to timely interventions. Our findings highlight the importance of close nephrologic monitoring of women with inherited dRTA during pregnancy. In addition to routine assessment of creatinine and proteinuria, caregivers should especially focus on acid-base status, plasma potassium and urinary tract infections. Patients should be screened for renal obstruction in the case of typical symptoms, UTI or renal failure. Furthermore, genetic identification of the underlying mutation may (a) support early nephrologic referral during pregnancy and a better management of the affected woman, and (b) help to avoid delayed diagnosis and reduce complications in affected newborns.

The optimal therapeutic regimen for managing childhood idiopathic nephrotic syndrome (INS) is still under debate. We have evaluated the choice of steroid regimen and of symptomatic treatment adopted by pediatricians and pediatric nephrologists in a large number of centers as the first step towards establishing a shared protocol This was a multicenter, retrospective study. A total of 231 children (132 admitted to pediatric units) aged 6 months to <15 years who presented with onset of nephrotic syndrome to 54 pediatric units and six pediatric nephrology units in Italy between 2007 and 2009 were eligible for entry into the study. Median steroid dosing was 55 (range 27-75) mg/m(2)/day. The overall median cumulative dose regimen for the first episode was 3,440 (1,904-6,035) mg/m(2), and the median duration of the therapeutic regimen was 21 (9-48) weeks. The total duration and cumulative steroid dose were significantly higher in patients treated by pediatricians than in those treated by pediatric nephrologists (p = 0.001 and p = 0.008). Among the patient cohort, 55, 64 and 22 % received albumin infusions, diuretics and acetyl salicylic acid treatment, respectively, but the laboratory and clinical data did not differ between children treated or not treated with symptomatic drugs. Albumin and diuretic use did not vary between patients in pediatric units and those in pediatric nephrology units. This study shows major differences in steroid and symptomatic treatment of nephrotic syndrome by pediatricians and pediatric nephrologists. As these differences can influence the efficacy of the treatments and the appearance of side-effects, shared guidelines and their implementation through widespread educational activities are necessary.

Conservative care for patients aged 75 years and older with CKD stage 5 as a treatment option besides dialysis was proposed officially in the Netherlands in October 2016. This national survey showed the current implementation of this option in Netherlands nephrology departments. A web-based survey was sent to medical managers of 60 nephrology departments in the Netherlands in August 2016. Twenty-one medical managers (35%) completed the survey. The term "conservative care" is frequently used and well known. The estimated number of patients in whom the decision for maximal conservative care was made in 2015 was 310 of 2249 patients with CKD stage 5 age 75 years and older (range 5-50 patients per department). 164 patients became symptomatic and received no dialysis. There is no official registration for this treatment option and patient category. The practice patterns vary widely. Only one of 21 respondents reported a conservative care outpatient clinic. Formal training or education regarding conservative care is not available in most of departments. 95% of respondents discussed this treatment option with their patients. General practitioners are always being informed about their patient's decision. Their main role is providing or organizing palliative care support at the end of life and discussing advance care planning. Most respondents (86%) considered to include their patients in a prospective multicentre observational study, conservative care versus dialysis. Conservative care as a treatment option for patients with CKD stage 5 aged 75 years and older is well established. The practice patterns are varied in the Netherlands. Follow-up studies are needed to see whether the new multidisciplinary guideline facilitates harmonization of practice pattern. Funding is needed to optimize the implementation of conservative care.

Management of BK virus nephropathy in kidney transplant recipients at the Royal Hospital - Clinical Audit - Oman.

2015-04-01

Nephropathy from BK virus (BKV) infection is a growing challenge in kidney transplant recipients globally. It is the result of contemporary potent immunosuppressives aimed at reducing acute rejection and improving allograft survival. Untreated BK virus infections lead to kidney allograft dysfunction or loss. Decreased immunosuppression is the principle treatment but predisposes to acute and chronic rejection. Screening for early detection and prevention of symptomatic BK virus nephropathy may improve outcomes. Although no approved antiviral drug is available, leflunomide, cidofovir, quinolones, and intravenous immunoglobulin have been used. Since the introduction of the new immunosuppressive agents in the transplant regimen at the Royal Hospital, Few cases of BK virus have been detected, and the challenge was to decide upon the best treatment option. The audit was carried out at the Royal Hospital-Oman between January 2010 and December 2012. The nephrology consultant and the clinical pharmacist reviewed all the BK cases and the Royal Hospital. Extensive literature review carried out by the pharmacist to look into the prevalence, prognosis and treatment of BK nephropathy. A treatment protocol was prepared by the clinical pharmacist through guidance of the consultant and was peer reviewed by team of clinical pharmacists and nephrology doctors and approved by the consultant. The audit included 19 patients with positive BK virus ployoma nephropathy. The treatment options were applied stepwise in all the patients with BK virus nephropathy with success rate more than 70%. BK virus nephropathy is emerging at an alarming rate and requires increasing awareness. The uses of current treatment options are still questionable. Our audit confirms that reducing immunosuppression appears to be the criterian standard for the treatment of BK nephropathy.

Supportive Care: Comprehensive Conservative Care in End-Stage Kidney Disease.

Comprehensive conservative (nondialytic) kidney care is widely recognized and delivered but until recently, has not been clearly defined. We provide a clear definition of comprehensive conservative care. This includes interventions to delay progression of kidney disease and minimize complications as well as detailed communication, shared decision making, advance care planning, and psychologic and family support. It does not include dialysis. Limited epidemiologic evidence from Australia and Canada indicates that, for every new person diagnosed with ESRD who receives dialysis or transplant, there is one new person who is managed conservatively (either actively or not). For older patients (those >75 or 80 years old) who have higher levels of comorbidity (such as diabetes and heart disease) and poorer functional status, the survival advantage of dialysis may be limited, and comprehensive conservative management may be considered; however, robust comparative evidence remains limited. Considerations of symptoms, quality of life, and hospital-free days are as or sometimes more important for patients and families than survival. There is some evidence that communication about possible conservative management options is generally insufficient, even where comprehensive conservative care pathways are already established. Symptom control and the cost-effectiveness of interventions are addressed in the companion papers within this Moving Points in Nephrology series. There is almost no evidence about which models of care and which interventions might be most beneficial in this population; future research on these areas is much needed. Meanwhile, consistency in definition of comprehensive conservative care and basing interventions on existing evidence about survival, symptoms, quality of life, and experience will maximize patient-centered and holistic care.

2016-01-01

Background and objectives Identifying predictors of kidney disease progression is critical toward the development of strategies to prevent kidney failure. Clinical notes provide a unique opportunity for big data approaches to identify novel risk factors for disease. Design, setting, participants, & measurements We used natural language processing tools to extract concepts from the preceding year’s clinical notes among patients newly referred to a tertiary care center’s outpatient nephrology clinics and retrospectively evaluated these concepts as predictors for the subsequent development of ESRD using proportional subdistribution hazards (competing risk) regression. The primary outcome was time to ESRD, accounting for a competing risk of death. We identified predictors from univariate and multivariate (adjusting for Tangri linear predictor) models using a 5% threshold for false discovery rate (q value <0.05). We included all patients seen by an adult outpatient nephrologist between January 1, 2004 and June 18, 2014 and excluded patients seen only by transplant nephrology, with preexisting ESRD, with fewer than five clinical notes, with no follow-up, or with no baseline creatinine values. Results Among the 4013 patients selected in the final study cohort, we identified 960 concepts in the unadjusted analysis and 885 concepts in the adjusted analysis. Novel predictors identified included high–dose ascorbic acid (adjusted hazard ratio, 5.48; 95% confidence interval, 2.80 to 10.70; q<0.001) and fast food (adjusted hazard ratio, 4.34; 95% confidence interval, 2.55 to 7.40; q<0.001). Conclusions Novel predictors of human disease may be identified using an unbiased approach to analyze text from the electronic health record. PMID:27927892

Time to Improve Informed Consent for Dialysis: An International Perspective.

The literature reveals that current nephrology practice in obtaining informed consent for dialysis falls short of ethical and legal requirements. Meeting these requirements represents a significant challenge, especially because the benefits and risks of dialysis have shifted significantly with the growing number of older, comorbid patients. The importance of informed consent for dialysis is heightened by several concerns, including: ( 1 ) the proportion of predialysis patients and patients on dialysis who lack capacity in decision making and ( 2 ) whether older, comorbid, and frail patients understand their poor prognosis and the full implications to their independence and functional status of being on dialysis. This article outlines the ethical and legal requirements for a valid informed consent to dialysis: ( 1 ) the patient was competent, ( 2 ) the consent was made voluntarily, and ( 3 ) the patient was given sufficient information in an understandable manner to make the decision. It then considers the application of these requirements to practice across different countries. In the process of informed consent, the law requires a discussion by the physician of the material risks associated with dialysis and alternative options. We argue that, legally and ethically, this discussion should include both the anticipated trajectory of the illness and the effect on the life of the patient with particular regard to the outcomes most important to the individual. In addition, a discussion should occur about the option of a conservative, nondialysis pathway. These requirements ensure that the ethical principle of respect for patient autonomy is honored in the context of dialysis. Nephrologists need to be open to, comfortable with, and skillful in communicating this information. From these clear, open, ethically, and legally valid consent discussions, a significant dividend will hopefully flow for patients, families, and nephrologists alike.

An Age-Calibrated Definition of Chronic Kidney Disease: Rationale and Benefits

PubMed Central

Delanaye, Pierre; Glassock, Richard J.; Pottel, Hans; Rule, Andrew D.

2016-01-01

Defining chronic kidney disease (CKD) is the subject of intense debate in the current nephrology literature. The debate concerns the threshold value of estimated glomerular filtration rate (eGFR) used to make the diagnosis of CKD. Current recommendations argue that a universal threshold of 60 mL/min/1.73m2 should be used. This threshold has been defended by epidemiological studies showing that the risk of mortality or end-stage renal disease increases with an eGFR below 60 mL/min/1.73m2. However, a universal threshold does not take into account the physiologic decline in GFR with ageing nor does it account for the risk of mortality and end-stage renal disease being trivial with isolated eGFR levels just below 60 mL/min/1.73m2 in older subjects and significantly increased with eGFR levels just above 60 mL/min/1.73m2 among younger patients. Overestimation of the CKD prevalence in the elderly (medicalisation of senescence) and underestimation of CKD (potentially from treatable primary nephrologic diseases) in younger patients is of primary concern. An age-calibrated definition of CKD has been proposed to distinguish age-related from disease-related changes in eGFR. For patients younger than 40 years, CKD is defined by eGFR below 75 mL/min/1.73m2. For patients with ages between 40 and 65 years, CKD is defined by 60 mL/min/1.73m2. For subjects older than 65 years without albuminuria or proteinuria, CKD is defined by eGFR below 45 mL/min/1.73m2. PMID:27057075

Despite the large burden of chronic kidney disease (CKD) in Hispanics, this population has been underrepresented in research studies. We describe the recruitment strategies employed by the Hispanic Chronic Renal Insufficiency Cohort Study, which led to the successful enrollment of a large population of Hispanic adults with CKD into a prospective observational cohort study. Recruitment efforts by bilingual staff focused on community clinics with Hispanic providers in high-density Hispanic neighborhoods in Chicago, academic medical centers, and private nephrology practices. Methods of publicizing the study included church meetings, local Hispanic print media, Spanish television and radio stations, and local health fairs. From October 2005 to July 2008, we recruited 327 Hispanics aged 21-74 years with mild-to-moderate CKD as determined by age-specific estimated glomerular filtration rate (eGFR). Of 716 individuals completing a screening visit, 49% did not meet eGFR inclusion criteria and 46% completed a baseline visit. The mean age at enrollment was 57.1 and 67.1% of participants were male. Approximately 75% of enrolled individuals were Mexican American, 15% Puerto Rican, and 10% had other Latin American ancestry. Eighty two percent of participants were Spanish-speakers. Community-based and academic primary care clinics yielded the highest percentage of participants screened (45.9% and 22.4%) and enrolled (38.2% and 24.5%). However, academic and community-based specialty clinics achieved the highest enrollment yield from individuals screened (61.9% to 71.4%). A strategy focused on primary care and nephrology clinics and the use of bilingual recruiters allowed us to overcome barriers to the recruitment of Hispanics with CKD. Copyright © 2012 Elsevier Inc.

To describe treatment practices for childhood pure membranous lupus nephritis (MLN). Survey study of Childhood Arthritis and Rheumatology Research Alliance and American Society of Pediatric Nephrology members. There were 117 respondents who completed the survey (60 pediatric nephrologists, 57 pediatric rheumatologists). Steroids and nonsteroid immunosuppression (NSI) were routinely used by the majority for MLN. Mycophenolate mofetil was the favored initial NSI. Nephrologists used steroids (60% vs 93%) and NSI (53% vs 87%) less often than did rheumatologists for MLN without nephrotic syndrome (NS). Pediatric rheumatologists and nephrologists both recommend steroids and NSI for children with MLN, with or without NS.

Educational Tools: Thinking Outside the Box

The understanding, study, and use of educational tools and their application to the education of adults in professional fields are increasingly important. In this review, we have compiled a description of educational tools on the basis of the teaching and learning setting: the classroom, simulation center, hospital or clinic, and independent learning space. When available, examples of tools used in nephrology are provided. We emphasize that time should be taken to consider the goals of the educational activity and the type of learners and use the most appropriate tools needed to meet the goals. Constant reassessment of tools is important to discover innovation and reforms that improve teaching and learning. PMID:26536900

Youth workers are based predominantly in the community and use a range of informal educational activities to help young people between the ages of 11 and 25 cultivate their personal and social development. The supraregional paediatric nephrology unit at Nottingham City Hospital successfully evaluated the role of a youth worker, funded by a national renal charity, and secured long-term funding for the post in 2000 (Hilton et al 2004, Watson 2004). This article describes the evolution of the youth service over a decade, following the amalgamation of two children's units into one site and the creation of a unified youth service for the Nottingham Children's Hospital in 2008.

We will not mention, however, HCV infection-related complications in the post-kidney transplantation setting. Extra-hepatic manifestations of HCV infection include mixed cryoglobulinemia, lymphoproliferative disorders, and renal disease. HCV infection has been reported in association with distinct histological patterns of glomerulonephritis in native kidneys.

The Evolving Complexity of the Podocyte Cytoskeleton.

PubMed

Schell, Christoph; Huber, Tobias B

2017-11-01

Podocytes exhibit a unique cytoskeletal architecture that is fundamentally linked to their function in maintaining the kidney filtration barrier. The cytoskeleton regulates podocyte shape, structure, stability, slit diaphragm insertion, adhesion, plasticity, and dynamic response to environmental stimuli. Genetic mutations demonstrate that even slight impairment of the podocyte cytoskeletal apparatus results in proteinuria and glomerular disease. Moreover, mechanisms underpinning all acquired glomerular pathologies converge on disruption of the cytoskeleton, suggesting that this subcellular structure could be targeted for therapeutic purposes. This review summarizes our current understanding of the function of the cytoskeleton in podocytes and the associated implications for pathophysiology.

Administrators sometimes face ethical dilemmas about the allocation of institutional resources. One such situation is when elective surgery cases require reserved ICU beds and the ICU is full. Such situations arise frequently in children's hospitals today. They are sometimes complicated by questions about whether every patient in the ICU belongs there.

Computational intelligence for the prediction of hemoglobin to guide the selection of erythropoiesis-stimulating agent dose results in improved anemia management. The models used for the prediction result from the use of individual patient data and help to increase the number of hemoglobin observations within the target range. The benefits of using these modeling techniques appear to be a decrease in erythropoiesis-stimulating agent use and a decrease in the number of transfusions. This study confirms the results of previous smaller studies and suggests that additional beneficial results may be achieved. Copyright © 2016 International Society of Nephrology.

2017-01-01

How social workers define and assess poverty is a matter of economic and social justice. Recent conceptual and measurement advances point to a multidimensional definition of poverty which captures material, social, and political deprivations. Using data from a survey, this article describes how nephrology social workers assess poverty among older adults living with a chronic kidney disease (N = 52). Results suggest respondents already conceive of poverty as a multidimensional experience, support awareness-raising about poverty, and primarily assess poverty by employment status, income, access to transportation, and education. Opportunities to expand poverty assessment in future work are promising.

Although recognized as a major complication of chronic kidney disease (CKD), the pathophysiology of the CKD-related mineral and bone disorder (CKD-MBD) is not completely understood. Recently, the inhibition of Wnt/β-catenin pathway in osteocytes by sclerostin has been shown to play a role in CKD-MBD. The study by Carrilo-Lopez et al. confirms this inhibition in an experimental model of CKD. Moreover, they describe direct actions of FGF23-Klotho on osteoblasts, increasing the expression of DKK1, another Wnt/β-catenin pathway inhibitor.

Job dissatisfaction, stress and burnout are linked to high rates of nurses leaving the profession, poor morale and poor patient outcomes. Haemodialysis (HD) nursing is uniquely characterised by the intense-prolonged interaction with patients who require complex technological care. A review of nine papers found that factors affecting job satisfaction were aspects of nursing care, organisational factors and length of time that a nurse has been working in nephrology nursing. Factors affecting job stress and burnout were due to interpersonal relationships with physicians, patient care activities, violence and abuse from patients, organisational factors and a lack of access to ongoing education. © 2010 European Dialysis and Transplant Nurses Association/European Renal Care Association.

Lithium is an effective drug in the treatment of bipolar disorder and other psychiatric and neurological diseases. Unfortunately, its therapeutic index is narrow. There are three types of lithium poisoning: acute poisoning (in untreated patients), acute on chronic poisoning, when an overdose is taken accidentally or with suicidal intent, in patients under treatment and chronic poisoning (patient treated with lithium) when drug intake is correct but excessive in relation to its elimination (increased dose or more often reduced clearance) resulting in lithium overload. In this last condition, the clinical presentation is primary neurological while therapy involves the nephrologist provided that lithium clearance is mainly renal and hemodialysis is the most effective method for removal.

The frequency of pregnancy in women on dialysis is extremely low, but the percentage of successful pregnancies in this context has increased over the years, with some studies placing the survival rate above 70%. These pregnancies are not exempt from both maternal and foetal complications, and so their management requires the joint efforts of nephrologists, gynaecologists, nurses, and nutritionists. Currently, we have been unable to establish consistent systematic treatment from both nephrological and gynaecological specialists in these patients. The main changes that need to be made are: increased time on dialysis, maintaining low levels of pre-dialysis urea, avoiding: maternal hypertension and hypotension, anaemia, urinary tract infections, and fluctuations in electrolytes. Adequate foetal monitoring is also necessary.

This paper investigates the design and implementation of a multimedia telemedicine application being undertaken by the Imaging Science and Information Systems Center of the Department of Radiology and the Division of Nephrology of the Department of Medicine at the Georgetown University Medical Center (GUMC). The Renal Dialysis Patient Monitoring network links GUMC, a remote outpatient dialysis clinic, and a nephrologist's home. The primary functions of the network are to provide telemedicine services to renal dialysis patients, to create, manage, transfer and use electronic health data, and to provide decision support and information services for physicians, nurses and health care workers. The technical parameters for designing and implementing such a network are discussed.

SGR reform and nephrology: difficult problems, potential solutions.

In light of the massive uncertainty with both the federal government in general and health policy priorities specifically, it is probably constructive to focus on the things we know for sure. In Medicare Part B reimbursement, the SGR system is fundamentally flawed, and must be replaced. All of Congress has recognized this fact, and there is legislation in the House that would move the ball forward on SGR repeal and replacement. Likewise, coordinated care models like ACOs offer a logical process for achieving a triple aim: improving individual health care, improving population health, and promoting cost efficiency in health care. Hopefully, policy makers in Washington will recognize and act on these truths as well.

Recent findings Interest in the history of psychiatry continues to grow, with an increasing emphasis on topics of current interest such as the history of psychopharmacology, electroconvulsive therapy, and the interplay between psychiatry and society. The scope of historical writing in psychiatry as of 2007 is as broad and varied as the discipline itself. Summary More than in other medical specialties such as cardiology or nephrology, treatment and diagnosis in psychiatry are affected by trends in the surrounding culture and society. Studying the history of the discipline provides insights into possible alternatives to the current crop of patent-protected remedies and trend-driven diagnoses. PMID:18852567

Lipids, inflammation, and chronic kidney disease: a SHARP perspective.

PubMed

Waters, David D; Vogt, Liffert

2018-04-01

Accumulating evidence indicates that inflammation plays a role in the initiation and progression of chronic kidney disease. In the Study of Heart and Renal Protection (SHARP) trial, higher baseline C-reactive protein and higher baseline low-density lipoprotein cholesterol levels were both associated with a higher risk of cardiovascular events, but higher baseline C-reactive protein levels were also associated with a higher risk of nonvascular events. Simvastatin/ezetimibe reduced cardiovascular events independent of baseline C-reactive protein levels. However, this observation does not exclude inflammation as a causal factor for cardiovascular disease development in chronic kidney disease patients.

Outcomes and renal function trajectory after acute kidney injury: the narrow road to perdition.

PubMed

Coca, Steven G

Analyses of the Grampian Laboratory Outcomes Morbidity and Mortality Study-II cohort support the notion that acute kidney injury (AKI) increases the risk of progression of glomerular filtration rate after recovery from AKI to a new baseline. However, the findings have to be considered in the bigger context of the absolute event rates for de novo progression versus nonrecovery and the competing risk of death after AKI. Examination of the data raises important implications for the design and implementation of clinical trials with interventions that target the AKI-to-chronic kidney disease transition.

In Brazil, as in the rest of the world, the prevalence of chronic kidney disease (CKD) is increasing. In order to alert the population, health professionals and authorities to this risk, in 2003, the Brazilian Society of Nephrology launched a CKD prevention campaign called 'Previna-se'. In addition, since its onset, Brazil has participated in the World Kidney Day efforts and has developed several prevention strategies. Here, we summarize the main strategies adopted in this campaign (population screening, events and meetings, distribution of educational materials, routine report of estimated glomerular filtration rate) and our initial results, sharing practical experience that could be useful in other developing countries.

Unlike in outpatient settings, the comparative costs of epoetin alpha (EPO) and darbepoetin alpha (DARB) have not been evaluated broadly from the inpatient hospital perspective. To develop a cost analytic model comparing hospital inpatient costs for erythropoiesis stimulating therapies within the nephrology and oncology settings. A cost analytic model incorporating erythropoietic drug, pharmacy, and nursing costs was developed from the inpatient hospital perspective to evaluate comparative costs of EPO and DARB. Erythropoietic drug costs were calculated using unit wholesale acquisition cost multiplied by the number of units or micrograms while comparing the following dosing regimens: EPO 3 times weekly, EPO once weekly, and DARB once weekly. Pharmacy costs included dispensing and delivery costs, while nursing costs incorporated administration time costs; all were calculated by estimated fractional hours per activity multiplied by hourly wages. The total frequency of erythropoiesis stimulating therapy administrations was determined based on the average hospital length of stay. The first erythropoiesis stimulating therapy dose was assumed to occur on day 3 of hospitalization. For total inpatient costs, a weighted average was calculated across disease states. One-way sensitivity analyses were conducted by varying length of stay, day of initial erythropoiesis stimulating therapy dose, pharmacy and nursing costs, and once-weekly DARB dose. EPO 3 times weekly was the least costly regimen across all disease states evaluated. Threshold analysis indicated that the cost of once-weekly DARB regimens would have to be reduced by 37% to equal the cost of EPO 3 times weekly for an average length of stay. Sensitivity analyses did not considerably affect the results. EPO 3 times weekly was found to be the least costly erythropoiesis stimulating therapy regimen for nephrology and oncology inpatients for the average length of stay as well as most other lengths of stay considered. Once-weekly EPO was the least costly erythropoiesis stimulating therapy regimen for several other lengths of stay, while once-weekly DARB was never found to be the least costly regimen.

The introduction of eGFR reporting and publication of national CKD guidelines has led to major challenges in primary and secondary care, leading to an increase in the number of referrals to nephrology clinics. We have shown that introduction of a renal patient care pathway reduces nephrology referrals and enables managed discharges of CKD patients to primary care. The aim of this article is to examine the outcome of patients discharged to primary care to find out if there is an associated risk with increased discharge supported by the patient pathway. The study was carried out within a single NHS Trust covering a population of 560,000. All patients discharged from the trust's renal outpatient clinic between June 2007 and July 2008 were identified. Patient notes and the local laboratory database systems were used to determine the source and timing of tests. A total of 31 new referrals and 57 regular follow-ups were discharged during this period. The median age of discharge was 67.5 years. Most subjects (60%) had CKD stage 3 at the time of discharge. A total of 23% of discharges were categorized as CKD stages 1, 2 or normal and 17% of patients had CKD stage 4. Overall, 93% had stable eGFRs prior to discharge, 77.5% of patients had blood pressure within threshold (140/90 according to UK CKD guidelines) and 97.7% of patients had haemoglobins >10 g/dl. Post-discharge 83% of patients had eGFRs recorded by their general practitioner and 92.6% of these were measured within appropriate time frames as per CKD guidelines. The majority of patients (82%) had either improved or stable eGFR post-discharge and only three patients had a significant decline in their eGFR. These data indicate that selected CKD patients can be appropriately discharged from secondary care and adequately monitored in primary care. Furthermore, we have shown that this was a safe practice for patients.

Medication errors may occur more frequently at discharge, making discharge counselling a vital facet of medication reconciliation. Discharge counselling is a recognized patient safety initiative for which pharmacists have appropriate expertise, but data are lacking about the barriers to provision of this service to adult inpatients by pharmacists. To determine the proportion of eligible patients who received discharge counselling, to quantify perceived barriers preventing pharmacists from performing discharge counselling, and to determine the relative frequency of barriers and associated time expenditures. In this prospective study, 8 pharmacists working in general medicine, medical oncology, or nephrology wards of an acute care hospital completed a survey for each of the first 50 patients eligible for discharge counselling on their respective wards from June 2010 to February 2011. Patients discharged to another facility (rehabilitation, palliative care, or long-term care), those with hospital stay less than 48 h before discharge, and those whose medications were unchanged from hospital admission were ineligible. Discharge counselling was performed for 116 (29%) of the 403 eligible patients and involved a median preparation time of 25 min and median counselling time of 15 min per patient. At least one documented barrier to discharge counselling existed for 295 (73%) of the patients. Several barriers to discharge counselling occurred significantly more frequently on the general medicine and oncology wards than on the nephrology ward (p < 0.05). The most common barrier was failure to notify the pharmacist about impending patient discharge (130/313 [41%]). Time constraints existed for 130 (32%) of the patients, the most common related to clarification of prescriptions (96 [24%]), creation of a medication list (69 [17%]), and faxing of prescriptions (64 [16%]). This study generated objective data about the barriers to and time constraints associated with medication discharge counselling by pharmacists. These findings should raise awareness of the challenges faced by pharmacists in busy hospital positions and may support avenues of change for their hospital discharge counselling programs.

For more than fifty years, low protein diets have been proposed to patients with kidney failure. However, the effects of these diets in preventing severe renal failure and the need for maintenance dialysis have not been resolved. To determine the efficacy of low protein diets in delaying the need to start maintenance dialysis. Cochrane Renal Group trials register, the Cochrane Central Register of Controlled Trials, MEDLINE, and EMBASE. Congress abstracts (American Society of Nephrology since 1990, European Dialysis Transplant Association since 1985, International Society of Nephrology since 1987). Direct contacts with investigators. Date of most recent search: December 2004. Randomised trials comparing two different levels of protein intake in adult patients suffering from moderate to severe renal failure, followed for at least one year. Two reviewers independently selected studies and extracted data. Statistical analyses were performed using the random effects model and the results expressed as relative risk (RR) for dichotomous outcomes with 95% confidence intervals (CI). Collection of the number of "renal deaths" defined as the need for starting dialysis, the death of a patient or a kidney transplant during the trial. Eight trials were identified from over 40 studies. A total of 1524 patients were analysed, 763 had received reduced protein intake and 761 a higher protein intake. Two hundred and fifty one renal deaths were recorded, 103 in the low protein diet and 148 in the higher protein diet group (RR 0.69, 95% CI 0.56 to 0.86, P = 0.0007). To avoid one renal death, 2 to 56 patients need to be treated with a low protein diet during one year. Reducing protein intake in patients with chronic kidney disease reduces the occurrence of renal death by 31% as compared with higher or unrestricted protein intake. The optimal level of protein intake cannot be confirmed from these studies.

Learning the facts in medical school is not enough: which factors predict successful application of procedural knowledge in a laboratory setting?

PubMed Central

2013-01-01

Background Medical knowledge encompasses both conceptual (facts or “what” information) and procedural knowledge (“how” and “why” information). Conceptual knowledge is known to be an essential prerequisite for clinical problem solving. Primarily, medical students learn from textbooks and often struggle with the process of applying their conceptual knowledge to clinical problems. Recent studies address the question of how to foster the acquisition of procedural knowledge and its application in medical education. However, little is known about the factors which predict performance in procedural knowledge tasks. Which additional factors of the learner predict performance in procedural knowledge? Methods Domain specific conceptual knowledge (facts) in clinical nephrology was provided to 80 medical students (3rd to 5th year) using electronic flashcards in a laboratory setting. Learner characteristics were obtained by questionnaires. Procedural knowledge in clinical nephrology was assessed by key feature problems (KFP) and problem solving tasks (PST) reflecting strategic and conditional knowledge, respectively. Results Results in procedural knowledge tests (KFP and PST) correlated significantly with each other. In univariate analysis, performance in procedural knowledge (sum of KFP+PST) was significantly correlated with the results in (1) the conceptual knowledge test (CKT), (2) the intended future career as hospital based doctor, (3) the duration of clinical clerkships, and (4) the results in the written German National Medical Examination Part I on preclinical subjects (NME-I). After multiple regression analysis only clinical clerkship experience and NME-I performance remained independent influencing factors. Conclusions Performance in procedural knowledge tests seems independent from the degree of domain specific conceptual knowledge above a certain level. Procedural knowledge may be fostered by clinical experience. More attention should be paid to the interplay of individual clinical clerkship experiences and structured teaching of procedural knowledge and its assessment in medical education curricula.

Background Issues related to renal replacement therapy in elderly people with end stage kidney disease (ESKD) are complex. There is inadequate empirical data related to: decision-making by older populations, treatment experiences, implications of dialysis treatment and treatment modality on quality of life, and how these link to expectations of ageing. Study population Participants for this study were selected from a larger quantitative study of dialysis and predialysis patients aged 65 years or older recruited from three nephrology services across New Zealand. All participants had reached chronic kidney disease (CKD) stage 5 and had undergone dialysis education but had not started dialysis or recently started dialysis within the past 6 months. Methodology Serial qualitative interviews were undertaken to explore the decision-making processes and subsequent treatment experiences of patients with ESKD. Analytical approach: A framework method guided the iterative process of analysis. Decision-making codes were generated within NVivo software and then compared with the body of the interviews. Results Interviews were undertaken with 17 participants. We observed that decision-making was often a fluid process, rather than occurring at a single point in time, and was heavily influenced by perceptions of oneself as becoming old, social circumstances, life events and health status. Limitations This study focuses on participants' experiences of decision-making about treatment and does not include perspectives of their nephrologists or other members of the nephrology team. Conclusions Older patients often delay dialysis as an act of self-efficacy. They often do not commit to a dialysis decision following predialysis education. Delaying decision-making and initiating dialysis were common. This was not seen by participants as a final decision about therapy. Predialysis care and education should be different for older patients, who will delay decision-making until the time of facing obvious uraemic symptoms, threatening blood tests or paternalistic guidance from their nephrologist.

2012-01-01

Background In April 2010, with an endorsement from the Ministry of Health of the People's Republic of China, the Chinese Society of Nephrology launched the first nationwide, web-based prospective renal data registration platform, the Chinese Renal Data System (CNRDS), to collect structured demographic, clinical, and laboratory data for dialysis cases, as well as to establish a kidney disease database for researchers and policy makers. Methods The CNRDS program uses information technology to facilitate healthcare professionals to create a blood purification registry and to deliver an evidence-based care and education protocol tailored to chronic kidney disease, as well as online forum for communication between nephrologists. The online portal https://www.cnrds.net is implemented as a Java web application using an Apache Tomcat web server and a MySQL database. All data are stored in a central databank to establish a Chinese renal database for research and publication purposes. Results Currently, over 270,000 clinical cases, including general patient information, diagnostics, therapies, medications, and laboratory tests, have been registered in CNRDS by 3,669 healthcare institutions qualified for hemodialysis therapy. At the 2011 annual blood purification forum of the Chinese Society of Nephrology, the CNRDS 2010 annual report was reviewed and accepted by the society members and government representatives. Conclusions CNRDS is the first national, web-based application for collecting and managing electronic medical records of patients with dialysis in China. It provides both an easily accessible platform for nephrologists to store and organize their patient data and acts as a communication platform among participating doctors. Moreover, it is the largest database for treatment and patient care of end-stage renal disease (ESRD) patients in China, which will be beneficial for scientific research and epidemiological investigations aimed at improving the quality of life of such patients. Furthermore, it is a model nationwide disease registry, which could potentially be used for other diseases. PMID:22369692

Treatment of chronic kidney disease (CKD) poses a huge burden to the healthcare system. To address the problem, the National Kidney Foundation of Malaysia embarked on a programme to screen for proteinuria and educate the public on CKD. The public was invited for health screening and the data collected over a 21 month period was analyzed. In total, 40400 adults from all the states in Malaysia were screened. The screening population had a mean age of 41 years, 30.1% had hypertension and 10.6% had diabetes. Proteinuria was detected in 1.4% and haematuria in 8.9% of the participants. Factors associated with the highest risk for proteinuria were the presence of diabetes (adjusted odds ratio (OR) 2.63 (95% confidence interval (CI) 2.16-3.21)), hypertension (OR 2.49 (95% CI 2.03-3.07)) and cardiac disease (OR 2.05 (95% CI 1.50-2.81)). Other risk factors identified were lower educational level, family history of kidney disease, hypercholesterolaemia, obesity and lack of regular exercise. Chinese had the lowest risk for proteinuria among the races (OR 0.71 (95% CI 0.57-0.87) compared with Malays). The combination of high blood glucose and high blood pressure (BP) substantially increased the risk for proteinuria (OR 38.1 for glucose ≥ 10 mmol/L and systolic BP ≥ 180 mm Hg and OR 47.9 for glucose ≥ 10 mmol/L and diastolic BP ≥ 110 mm Hg). The prevalence of proteinuria in Malaysia is similar to other countries. The major risk factors for proteinuria were diabetes, hypertension and cardiac disease. The presence of both high blood pressure and high blood glucose exert a synergistic effect in substantially increasing the risk for proteinuria. © 2013 The Authors.

In 2013, the Italian Society of Nephrology joined forces with Nephrocare-Italy to create a clinical research cohort of patients on file in the data-rich clinical management system (EUCLID) of this organization for the performance of observational studies in the hemodialysis (HD) population. To see whether patients in EUCLID are representative of the HD population in Italy, we set out to compare the whole EUCLID population with patients included in the regional HD registries in Emilia-Romagna (Northern Italy) and in Calabria (Southern Italy), the sole regions in Italy which have systematically collected an enlarged clinical data set allowing comparison with the data-rich EUCLID system. An analysis of prevalent and incident patients in 2010 and 2011 showed that EUCLID patients had a lower prevalence of coronary heart disease, peripheral vascular disease, heart failure, valvular heart disease, liver disease, peptic ulcer and other comorbidities and risk factors and a higher fractional urea clearance (Kt/V) than those in the Emilia Romagna and Calabria registries. Accordingly, survival analysis showed a lower mortality risk in the EUCLID 2010 and 2011 cohorts than in the combined two regional registries in the corresponding years: for 2010, hazard ratio (HR) EUCLID vs. Regional registries: 0.80 [95% confidence interval: 0.71-0.90]; for 2011, HR: 0.76 [0.65-0.90]. However, this difference was nullified by statistical adjustment for the difference in comorbidities and risk factors, indicating that the longer survival in the EUCLID database was attributable to the lower risk profile of patients included in that database. This preliminary analysis sets the stage for future observational studies and indicates that appropriate adjustment for difference in comorbidities and risk factors is needed to generalize to the Italian HD population analyses based on the data-rich EUCLID database.

Vascular Access Creation before Hemodialysis Initiation and Use: A Population-Based Cohort Study

Background and objectives In Canada, approximately 17% of patients use an arteriovenous access (fistula or arteriovenous graft) at commencement of hemodialysis, despite guideline recommendations promoting its timely creation and use. It is unclear if this low pattern of use is attributable to the lack of surgical creation or a high nonuse rate. Design, setting, participants, & measurements Using large health care databases in Ontario, Canada, a population-based cohort of adult patients (≥18 years old) who initiated hemodialysis as their first form of RRT between 2001 and 2010 was studied. The aims were to (1) estimate the proportion of patients who had an arteriovenous access created before starting hemodialysis and the proportion who successfully used it at hemodialysis start, (2) test for secular trends in arteriovenous access creation, and (3) estimate the effect of late nephrology referral and patient characteristics on arteriovenous access creation. Results There were 17,183 patients on incident hemodialysis. The mean age was 65.8 years, 60% were men, and 40% were referred late to a nephrologist; 27% of patients (4556 of 17,183) had one or more arteriovenous accesses created, and the median time between arteriovenous access creation and hemodialysis start was 184 days. When late referrals were excluded, 39% of patients (4007 of 10,291) had one or more arteriovenous accesses created, and 27% of patients (2724 of 10,291) used the arteriovenous access. Since 2001, there has been a decline in arteriovenous access creation before hemodialysis initiation. Women, higher numbers of comorbidities, and rural residence were consistently associated with lower rates of arteriovenous access creation. These results persisted even after removing patients with <6 months nephrology care or who had AKI 6 months before starting hemodialysis. Conclusions In Canada, arteriovenous access creation before hemodialysis initiation is low, even among patients followed by a nephrologist. Better understanding of the barriers and influencers of arteriovenous access creation is needed to inform both clinical care and guidelines. PMID:25568219

Chronic kidney disease (CKD) is associated with high morbidity and mortality. Hence, CKD patients are often in chronic psychological distress. The objective of the study was to describe factors associated with psychological distress of CKD patients attending National Nephrology Unit. A descriptive cross-sectional study was conducted among 382 CKD patients above 18 years of age applying systematic sampling. The data was collected using self-administered questionnaires to assess the psychological distress (GHQ-12), social support (SSQ6), coping strategies (BRIEFCOPE), pain (0 to 10 numeric pain rating scale), and physical role limitation due to ill health (SF36QOL). Sociodemographic and disease-related data were collected using an interviewer administered questionnaire and a data extraction sheet. Multiple logistic regression was applied for determining the associated factors. The results were expressed as adjusted odds ratio (AOR) and 95% confidence intervals (95% CI). Percentage of psychological distress was 55.2% (95% CI: 48.4% to 62%). Poor social support (AOR = 1.81, 95% CI: 1.14-2.88), low satisfaction with the social support received (AOR = 4.14, 95% CI: 1.59-10.78), stages IV and V of CKD (AOR = 2.67, 95% CI: 1.65-4.20), presence of comorbidities (AOR = 2.38, 95% CI: 1.21-4.67), within one year of diagnosis (AOR = 2.23, 95% CI: 1.36-3.67), low monthly income (AOR = 2.26, CI: 1.26-4.06), higher out-of-pocket expenditure per month (AOR = 1.75, 95% CI: 1.75-1.99), and being a female (AOR = 2.95, 95% CI: 1.79-4.9) were significantly associated with psychological distress. More than half of the CKD patients were psychologically distressed. Factors such as financial and social support will be worth considering early because of their modifiability.

Background Nephrogenic diabetes insipidus (NDI) is a rare disease whose complications include polyuria, renal dysfunction, growth disorder and mental retardation. The details of NDI’s clinical course have been unclear. To address this uncertainty, we performed a large investigation of the clinical course of NDI in Japan. Methods Between December 2009 and March 2011, we provided a primary questionnaire to 26,282 members of the Japan Endocrine Society, the Japanese Urological Association, the Japanese Society for Pediatric Endocrinology, the Japanese Society for Pediatric Nephrology, the Japanese Society of Nephrology, the Japanese Society of Neurology and the Japanese Society of Pediatric Urology. In addition, we provided a secondary questionnaire to 121 members who reported experience with cases of NDI. We asked about patient’s age at onset, diagnosis, complications, effect of treatment and patient’s genotype. Results We enrolled 173 patients with NDI in our study. Of these NDI patients, 143 were congenital and 30 were acquired. Of the 173, 73 patients (42%) experienced urologic complications. Among the 143 with congenital NDI, 20 patients (14%) had mental retardation. Patients with NDI mainly received thiazide diuretics, and some patients responded to treatment with desmopressin acetate (DDAVP). Gene analyses were performed in 87 patients (61%) with congenital NDI, revealing that 65 patients had an arginine vasopressin receptor type 2 (AVPR2) gene mutation and that 8 patients (9.2%) had an aquaporin 2 (AQP2) gene mutation. Patients with the AVPR2 mutation (D85N) generally showed a mild phenotype, and we found that DDAVP was generally an effective treatment for NDI among these patients. Conclusion We suggest that adequate diagnosis and treatment are the most important factors for improving prognoses. We further suggest that gene analysis should be performed for optimal treatment selection and the early detection of NDI among siblings. PMID:25324589

This study aims to characterise the timing of referral to a paediatric nephrology unit of children who develop end-stage kidney disease (ESKD). This study also aims to determine whether late referral (LR) influences outcomes and to explore factors that may lead to LR. A retrospective case review of all incident patients with ESKD who received renal replacement therapy (RRT) at a single paediatric centre. Time between referral to a paediatric nephrologist and commencement of RRT, demographic and clinical data were collated. Estimated glomerular filtration rate (eGFR) at referral was calculated using height and creatinine. LR was defined as having an eGFR ≤ 30 mL/min/1.73 m(2) when first seen by a paediatric nephrologist. RRT was initiated for 74 patients < 18 years of age between 1988 and 2010. The median age at referral was 2.0 years (birth-15.9 years) and age at RRT was 10.0 years (6 days-17.4 years). Children referred before age 1 year (41%) had a more prolonged course before ESKD. Median (interquartile range) eGFR at referral of children > 1 year was 27.2 (9.0-52.0) mL/min/1.73 m(2) . Twenty-two (55%) of these children were referred late (LR) with an eGFR ≤ 30 mL/min/1.73 m(2) . LR patients were more likely to have glomerulonephritis or haemolytic uraemic syndrome and to live in a remote or outer regional area. LR patients had higher urea, lower haemoglobin and were more likely to receive haemodialysis via a vascular catheter. A significant proportion of children who develop ESKD are referred late to nephrology units with potentially preventable complications. Aetiology of renal disease and geographic isolation contribute to LR. © 2011 The Authors.

To review issues and challenges in caring for hemodialysis patients with anemia of chronic kidney disease, specifically focusing on the effects of longer erythropoiesis-stimulating agent (ESA) dosing intervals on processes of care. PubMed searches were performed limited to the last 10 years to February 2011, focusing on articles in English that were 'clinical trials,' assessed processes of care, measured associations of hemoglobin (Hb) with outcomes, and explored/analyzed extended dosing intervals of ESAs in hemodialysis patients and recommendations for increasing the quality of care of these patients. Some limitations included the fact that a meta-analysis was not conducted; many studies were associative and therefore unable to prove causality; and none of the clinical trials directly compared the impact of more frequent or less frequent ESA dosing strategies on patient care and outcomes. Progress over the past several decades has been substantial; however, unmet needs remain and there is room for improvement in efficiencies of care. Many patients fail to meet Hb targets, and nephrology professionals' time is consumed with preparing, administering, and monitoring therapy. Direct interaction between patients and care providers has been lost as attention has shifted to 'cost-effective' (not necessarily patient-centered) ways to deliver care. Use of ESAs at longer dosage intervals represents one opportunity to improve efficiency of care. Newer ESAs have been developed for less frequent dosing. Once-monthly dosing decreases time spent administering/monitoring therapy and allows nephrology professionals to provide comprehensive renal care, wherein the patient rather than task-oriented processes becomes the primary focus. A fragmented, uncoordinated care-delivery model heightens the urgency to systematically address issues related to delivery of care and improve efficiencies in anemia management as part of the patient-centered approach. ESAs designed for administration at longer intervals may effectively and reliably achieve Hb targets with once-monthly dosing, thereby decreasing time spent administering/monitoring therapy.

Patients with CKD are asked to perform self-management tasks including dietary changes, adhering to medications, avoiding nephrotoxic drugs, and self-monitoring hypertension and diabetes. Given the effect of aging on functional capacity, self-management may be especially challenging for older patients. However, little is known about the specific challenges older adults face maintaining CKD self-management regimens. We conducted an exploratory qualitative study designed to understand the relationship among factors facilitating or impeding CKD self-management in older adults. Six focus groups ( n =30) were held in August and September of 2014 with veterans≥70 years old with moderate-to-severe CKD receiving nephrology care at the Atlanta Veterans Affairs Medical Center. Grounded theory with a constant comparative method was used to collect, code, and analyze data. Participants had a mean age (range) of 75.1 (70.1-90.7) years, 60% were black, and 96.7% were men. The central organizing concept that emerged from these data were managing complexity. Participants typically did not have just one chronic condition, CKD, but a number of commonly co-occurring conditions. Recommendations for CKD self-management therefore occurred within a complex regimen of recommendations for managing other diseases. Participants identified overtly discordant treatment recommendations across chronic conditions ( e.g., arthritis and CKD). Prioritization emerged as one effective strategy for managing complexity ( e.g. , focusing on BP control). Some patients arrived at the conclusion that they could group concordant recommendations to simplify their regimens ( e.g. , protein restriction for both gout and CKD). Among older veterans with moderate-to-severe CKD, multimorbidity presents a major challenge for CKD self-management. Because virtually all older adults with CKD have multimorbidity, an integrated treatment approach that supports self-management across commonly occurring conditions may be necessary to meet the needs of these patients.

Individuals are adherent to approximately 50% of their prescribed medications, which decreases when multiple, chronic conditions are involved. To examine factors affecting adherence to multiple prescribed medications for consumers with co-existing diabetes and chronic kidney disease (diabetic kidney disease) from the time of prescription to the time they took their medications. A descriptive exploratory design was used incorporating in-depth interviews and focus groups. The diabetes and nephrology departments of two metropolitan, public hospitals in Melbourne, Australia. A convenience sample of 23 consumers with diabetic kidney disease participated in an in-depth interview. Inclusion criteria involved English-speaking individuals, aged > or =18 years, with co-existing diabetes and chronic kidney disease, and who were mentally competent. Exclusion criteria included impending commencement on dialysis, pregnancy, an aggressive form of cancer, or a mental syndrome that was not stabilised with medication. Sixteen health professionals working in diabetes and nephrology departments in Melbourne, Australia also participated in one of two focus groups. In-depth structured interviews and focus groups were conducted and analysed according to a model of medication adherence. Consumers were not convinced of the need, effectiveness and safety of all of their medications. Alternatively, health professionals focussed on the importance of consumers taking their medications as prescribed and believed that the risk of medication-related adverse effects was over-rated. Accessing prescribed medications and difficulties surrounding continuity of care contributed to consumers' unintentional medication non-adherence. In particular, it was hard for consumers to persist taking their ongoing medication prescriptions. Healthcare system inadequacies were highlighted, which affected relationships between consumers with diabetic kidney disease and health professionals. Acknowledging the barriers as perceived by consumers with diabetic kidney disease can facilitate effective communication and partnerships with health professionals necessary for medication adherence and medication safety.

Errors in drug dosing lead to poor patient outcomes and are common in patients with chronic kidney disease (CKD). Because the majority of patients with CKD are being treated by physicians specializing in internal medicine, we studied the awareness and knowledge that internal medicine resident trainees (IMRTs) have regarding the correct dosage of commonly used analgesic and neuropsychotropic medications for patients with CKD. We surveyed 353 IMRTs about their awareness of whether a medication needs dose adjustment in patients with CKD and knowledge for medication adjustment by level of glomerular filtration rate. There were high percentages for lack of awareness and knowledge. For analgesics, this lack of awareness/knowledge was highest for acetaminophen (awareness 83.0%, knowledge 90.9%). For neuropsychotropics, this was highest for paroxetine (awareness 74.5%, knowledge 91.5%). Analyses for postgraduate year (PGY) -1 trainees and PGY-2 trainees for analgesics showed higher odds for lack of awareness for tramadol (PGY-1 odds ratio [OR] 2.37, 95% confidence interval [CI] 1.2-4.62, P < 0.05; PGY-2 OR 2.34, 95% CI 1.16-4.72, P < 0.05) and for lack of knowledge for meperedine (PGY-1 OR 4.01, 95% CI 1.81-8.89, P < 0.05; PGY-2 OR 3.30, 95% CI 1.44-7.59, P < 0.05). Nephrology residency rotation for the neuropsychotropic medication of gabapentin showed lower odds for both lack of awareness (OR 0.56, 95% CI 0.32-0.97, P < 0.05) and knowledge (OR 0.52, 95% CI 0.27-0.997, P < 0.05). Awareness and knowledge are poor among IMRTs for dose adjustments of analgesics and neuropsychotropic medication classes in patients with CKD. There should be a renewed focus during IMRTs' residency on additional nephrology exposure and formal didactic educational training to help them better manage complex treatment regimens to prevent medication dosing errors.

Renal failure is one of the main causes of death in patients with Fabry disease (FD). Due to the low prevalence of FD, delayed diagnosis and misdiagnosis, often the correct diagnosis is made when organ damage is already present. Early recognition of the disease would allow the prevention of severe complications and the premature death of patients with FD. We present here the PrEFiNE project, which includes a wide spectrum of activities with the aim of improve knowledge and diagnosis of FD. The project is sponsored by Shire Iberia (http://shireiberica.com/) From January 2016 to the end of 2017 several activities will be carried out, starting with a survey to evaluate current FD knowledge among nephrologists; in addition some studies to assess prevalence of this disease will be performed. One study will include patients receiving dialysis, another study will cover kidney transplant patients, and a pilot study in chronic kidney disease in stage 3-5 predialysis. Also planned is a pharmacoeconomic study to focus on burden of FD. At the same time medical education activities will be conducted both on line and on site. Plan for dissemination will include medical publications and diffusion to media. PrEFiNE Project will finish with the publication of a compilation book on FD in Nephrology including all planned activities and proposing recommendations based on results and detected unmet needs. PrEfiNE Plan will be coordinated by severa scientific committees, one at national level and 10 other regionals comittees, tha will be responsible to ensure the maximum scientific quality of proposed activities. An advisory board will supervise the project. PrEfiNE project will evaluate an action plan focused on improving FD knowledge to make necessary recommendations for an early recognition of the disease. In addition will generate a plan to improve previously undetected needs. Copyright © 2016 Sociedad Española de Nefrología. Published by Elsevier España, S.L.U. All rights reserved.

BK virus-associated hemorrhagic cystitis after pediatric stem cell transplantation

2014-01-01

Hemorrhagic cystitis is a common stem cell transplantation-related complication. The incidence of early-onset hemorrhagic cystitis, which is related to the pretransplant conditioning regimen, has decreased with the concomitant use of mesna and hyperhydration. However, late-onset hemorrhagic cystitis, which is usually caused by the BK virus, continues to develop. Although the BK virus is the most common pathogenic microorganism of poststem cell transplantation late-onset hemorrhagic cystitis, pediatricians outside the hemato-oncology and nephrology specialties tend to be unfamiliar with hemorrhagic cystitis and the BK virus. Moreover, no standard guidelines for the early diagnosis and treatment of BK virus-associated hemorrhagic cystitis after stem cell transplantation have been established. Here, we briefly introduce poststem cell transplantation BK virus-associated hemorrhagic cystitis. PMID:25653684

Peritoneal Dialysis in Diabetics: There Is Room for More

2011-01-01

End stage renal disease diabetic patients suffer from worse clinical outcomes under dialysis-independently of modality. Peritoneal dialysis offers them the advantages of home therapy while sparing their frail vascular capital and preserving residual renal function. Other benefits and potential risks deserve discussion. Predialysis intervention with early nephrology referral, patient education, and multidisciplinary support are recommended. Skilled and updated peritoneal dialysis protocols must be prescribed to assure better survival. Optimized volume control, glucose-sparing peritoneal dialysis regimens, and elective use of icodextrin are key therapy strategies. Nutritional evaluation and support, preferential use of low-glucose degradation products solutions, and prescription of renin-angiotensin-aldosterone system acting drugs should also be part of the panel to improve diabetic care under peritoneal dialysis.

As the importance of providing patient-centered palliative care for patients with advanced illnesses gains attention, standard dialysis delivery may be inconsistent with the goals of care for many patients with ESRD. Many dialysis patients with life expectancy of <1 year may desire a palliative approach to dialysis care, which focuses on aligning patient treatment with patients' informed preferences. This commentary elucidates what comprises a palliative approach to dialysis care and describes its potential and appropriate use. It also reviews the barriers to integrating such an approach into the current clinical paradigm of care and existing infrastructure and outlines system-level changes needed to accommodate such an approach.

The large multinational, randomised, double-blind LEADER (Liraglutide Effect and Action in Diabetes: Evaluation of Cardiovascular Outcome Results - A Long Term Evaluation) trial recently reported the cardiovascular (CV) benefits achieved with liraglutide therapy in type 2 diabetes mellitus (T2DM). This editorial analyses the primary and secondary CV outcomes (CVO) results of the LEADER trial, and discusses the impact these will have on clinical practice of diabetes in specific, and medicine in general. It delves into the evolution of clinical and biochemical outcomes used in diabetes, and discusses the role of liraglutide in shaping future outcomes. The editorial describes the potential role of liraglutide in primary, secondary and tertiary prevention of CV disease (CVD), and suggests exaptation of this molecule for use in cardiology, nephrology and neurology.

Lactic Acidosis in a Patient with Type 2 Diabetes Mellitus.

PubMed

Weisberg, Lawrence S

2015-08-07

Lactic acidosis occurs when lactate production exceeds its metabolism. There are many possible causes of lactic acidosis, and in any given patient, several causes may coexist. This Attending Rounds presents a case in point. Metformin's role in the pathogenesis of lactic acidosis in patients with diabetes mellitus is complex, as the present case illustrates. The treatment of lactic acidosis is controversial, except for the imperative to remedy its underlying cause. The use of sodium bicarbonate to treat the often alarming metabolic derangements may be quite efficacious in that regard but is of questionable benefit to patients. Renal replacement therapies (RRTs) have particular appeal in this setting for a variety of reasons, but their effect on clinical outcomes is untested.

A 42-year-old indigenous Maya man presented to a non-profit clinic in rural Guatemala with signs, symptoms and laboratory values consistent with uncontrolled diabetes. Despite appropriate treatment, approximately 18 months after presentation, he was found to have irreversible end-stage renal disease (ESRD) of uncertain aetiology. He was referred to the national public nephrology clinic and subsequently initiated home-based continuous ambulatory peritoneal dialysis. With primary care provided by the non-profit clinic, his clinical status improved on dialysis, but socioeconomic and psychological challenges persisted for the patient and his family. This case shows how care for people with ESRD in low- and middle-income countries requires scaling up renal replacement therapy and ensuring access to primary care, mental healthcare and social work services.

Symptom Management of the Patient with CKD: The Role of Dialysis

PubMed Central

Cabrera, Valerie Jorge; Hansson, Joni; Kliger, Alan S.

2017-01-01

As kidney disease progresses, patients often experience a variety of symptoms. A challenge for the nephrologist is to help determine if these symptoms are related to advancing CKD or the effect of various comorbidities and/or medications prescribed. The clinician also must decide the timing of dialysis initiation. The initiation of dialysis can have a variable effect on quality of life measures and the alleviation of uremic signs and symptoms, such as anorexia, fatigue, cognitive impairment, depressive symptoms, pruritus, and sleep disturbances. Thus, the initiation of dialysis should be a shared decision–making process among the patient, the family and the nephrology team; information should be provided, in an ongoing dialogue, to patients and their families concerning the benefits, risks, and effect of dialysis therapies on their lives.

Most non-directed donors (NDDs) decide to donate on their own and contact the transplant centre directly. Some NDDs decide to donate in response to community solicitation such as newspaper ads or donor drives. We wished to explore whether subtle coercion might be occurring in such NDDs who are part of a larger community. One successful organization in a community in Brooklyn, NY, provides about 50 NDDs per year for recipients within that community. The donors answer ads in local papers and attend donor drives. Herein, we evaluated the physical and emotional outcomes of community-solicited NDDs in comparison to traditional NDDs who come from varied communities and are not responding to a specific call for donation. An assessment of coercion was used as well. © 2015 Asian Pacific Society of Nephrology.

Esterhuizen, Tonya M; Thabane, Lehana

2016-06-01

Meta-analysis, a statistical combination of results of several trials to produce a summary effect, has been subject to criticism in the past, mainly for the reasons of poor quality of included studies, heterogeneity between studies meta-analyzed and failing to address publication bias. These limitations can cause the results to be misleading, which is important if policy and practice decisions are based on systematic reviews and meta-analyses. We elaborate on these limitations and illustrate them with examples from the nephrology literature. Finally, we present some potential solutions, notably, education in meta-analysis for evidence producers and consumers as well as the use of individual patient data for meta-analyses. © The Author 2016.

In the face of ever-increasing incidence and prevalence of kidney disease worldwide, the unmet need for new treatments is unprecedented. Precision medicine is defined as the use of modern technologies to identify mechanisms of diseases in individual patients, and thus deploy treatment using tailored, targeted approaches, in the hopes of avoiding unnecessary toxicities and complications. Is there a place for kidney disease therapeutics in this space? If so, what is required to make significant progress toward precision nephrology? To answer these critical questions, we present a series of personalized comments corresponding to the responses offered to these very questions during the Inaugural Glom-NExT Symposium held at Harvard Medical School on October 23, 2014, a national meeting focused exclusively on kidney disease therapeutics.

Renal control of calcium, phosphate, and magnesium homeostasis.

PubMed

Blaine, Judith; Chonchol, Michel; Levi, Moshe

2015-07-07

Calcium, phosphate, and magnesium are multivalent cations that are important for many biologic and cellular functions. The kidneys play a central role in the homeostasis of these ions. Gastrointestinal absorption is balanced by renal excretion. When body stores of these ions decline significantly, gastrointestinal absorption, bone resorption, and renal tubular reabsorption increase to normalize their levels. Renal regulation of these ions occurs through glomerular filtration and tubular reabsorption and/or secretion and is therefore an important determinant of plasma ion concentration. Under physiologic conditions, the whole body balance of calcium, phosphate, and magnesium is maintained by fine adjustments of urinary excretion to equal the net intake. This review discusses how calcium, phosphate, and magnesium are handled by the kidneys. Copyright © 2015 by the American Society of Nephrology.

Chronic kidney disease is a significant contributor to mortality and morbidity worldwide, and the number of people who require dialysis or transplantation continues to increase. People on dialysis are 15 times more likely to die than the general population. Dialysis is also costly, intrusive, and time-consuming and imposes an enormous burden on patients and their families. This escalating problem has spurred a proliferation of trials in dialysis, yet health and quality of life remain poor. The reasons for this are complex and varied but are attributable in part to problems in the design and reporting of studies, particularly outcome selection. Problems related to outcomes include use of unvalidated surrogates, outcomes of little or no relevance to patients, highly variable outcome selection limiting comparability across studies, and bias in reporting outcomes. The aim of the Standardised Outcomes in Nephrology-Haemodialysis (SONG-HD) study is to establish a core outcome set for haemodialysis trials, to improve the quality of reporting, and the relevance of trials conducted in people on haemodialysis. SONG-HD is a five-phase project that includes the following: a systematic review to identify outcomes that have been reported in haemodialysis systematic reviews and trials; nominal group technique with patients and caregivers to identify, rank, and describe reasons for their choices; qualitative stakeholder interviews with patients, caregivers, clinicians, researchers, and policy makers to elicit individual values and perspectives on outcomes for haemodialysis trials; a three-round Delphi survey with stakeholder groups to distil and generate a prioritised list of core outcomes; and a consensus workshop to establish a core outcome set for haemodialysis trials. Establishing a core outcome set to be consistently measured and reported in haemodialysis trials will improve the integrity, transparency, usability, and contribution of research relevant to patients requiring haemodialysis; ensure that outcomes of relevance to all stakeholders are consistently reported across trials; and mitigate against outcome reporting bias. Ultimately, patients will be more protected from potential harm, patients and clinicians will be better able to make informed decisions about treatment, and researchers and policy makers will be more able to maximise the value of research to the public.

The STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) statement was published in October 2007 to improve quality of reporting of observational studies. The aim of this review was to assess the impact of the STROBE statement on observational study reporting and study design quality in the nephrology literature. Systematic literature review. European and North American, Pre-dialysis Chronic Kidney Disease (CKD) cohort studies. Studies assessing the association between CKD and mortality in the elderly (>65 years) published from 1st January 2002 to 31st December 2013 were included, following systematic searching of MEDLINE & EMBASE. Time period before and after the publication of the STROBE statement. Quality of study reporting using the STROBE statement and quality of study design using the Newcastle Ottawa Scale (NOS), Scottish Intercollegiate Guidelines Network (SIGN) and Critical Appraisal Skills Programme (CASP) tools. 37 papers (11 Pre & 26 Post STROBE) were identified from 3621 potential articles. Only four of the 22 STROBE items and their sub-criteria (objectives reporting, choice of quantitative groups and description of and carrying out sensitivity analysis) showed improvements, with the majority of items showing little change between the period before and after publication of the STROBE statement. Pre- and post-period analysis revealed a Manuscript STROBE score increase (median score 77.8% (Inter-quartile range [IQR], 64.7-82.0) vs 83% (IQR, 78.4-84.9, p = 0.05). There was no change in quality of study design with identical median scores in the two periods for NOS (Manuscript NOS score 88.9), SIGN (Manuscript SIGN score 83.3) and CASP (Manuscript CASP score 91.7) tools. Only 37 Studies from Europe and North America were included from one medical specialty. Assessment of study design largely reliant on good reporting. This study highlights continuing deficiencies in the reporting of STROBE items and their sub-criteria in cohort studies in nephrology. There was weak evidence of improvement in the overall reporting quality, with no improvement in methodological quality of CKD cohort studies between the period before and after publication of the STROBE statement.

Background and Objectives Chronic kidney disease is a persistent chronic health condition commonly seen in pediatric nephrology programs. Our study aims to evaluate the sensitivity of the Patient Reported Outcomes Measurement Information System (PROMIS) pediatric instrument to indicators of disease severity and activity in pediatric chronic kidney disease. Methods This cross sectional study included 233 children 8–17 years old with chronic kidney disease from 16 participating institutions in North America. Disease activity indicators, including hospitalization in the previous 6 months, edema, and number of medications consumed daily, as well as disease severity indicators of kidney function and coexisting medical conditions were captured. PROMIS domains, including depression, anxiety, social-peer relationships, pain interference, fatigue, mobility, and upper extremity function, were administered via web-based questionnaires. Absolute effect sizes (AES) were generated to demonstrate the impact of disease on domain scores. Four children were excluded because of missing GFR estimations. Results 221 of the 229 children included in the final analysis completed the entire PROMIS questionnaire. Unadjusted PROMIS domains were responsive to chronic kidney disease activity indicators and number of coexisting conditions. PROMIS domain scores were worse in the presence of recent hospitalizations (depression AES 0.33, anxiety AES 0.42, pain interference AES 0.46, fatigue AES 0.50, mobility AES 0.49), edema (depression AES 0.50, anxiety AES 0.60, pain interference AES 0.77, mobility AES 0.54) and coexisting medical conditions (social peer-relationships AES 0.66, fatigue AES 0.83, mobility AES 0.60, upper extremity function AES 0.48). Conclusions The PROMIS pediatric domains of depression, anxiety, social-peer relationships, pain interference, and mobility were sensitive to the clinical status of children with chronic kidney disease in this multi-center cross sectional study. We demonstrated that a number of important clinical characteristics including recent history of hospitalization and edema affected patient perceptions of depression, anxiety, pain interference, fatigue and mobility. The PROMIS instruments provide a potentially valuable tool to study the impact of chronic kidney disease. Additional studies will be required to assess responsiveness in PROMIS score with changes in disease status over time. PMID:24908324

Very low-protein intake during chronic kidney disease (CKD) improves metabolic disorders and may delay dialysis start without compromising nutritional status, but concerns have been raised on a possible negative effect on survival during dialysis. This study aimed at evaluating whether a very low-protein diet during CKD is associated with a greater risk of death while on dialysis treatment. This is an historical, cohort, controlled study, enrolling patients at dialysis start previously treated in a tertiary nephrology clinic with a very low-protein diet supplemented with amino acids and ketoacids (s-VLPD group, n = 184) or without s-VLPD [tertiary nephrology care (TNC) group, n = 334] and unselected patients [control (CON) group, n = 9.092]. The major outcome was survival rate during end-stage renal disease associated to s-VLPD treatment during CKD. The propensity score methods and Cox regression model were used to match groups at the start of dialysis to perform survival analysis and estimate adjusted hazard ratio (HR). In s-VLPD, TNC and CON groups, average age was 67.5, 66.0 and 66.3 years, respectively (P = 0.521) and male prevalence was 55, 55 and 62%, respectively (P = 0.004). Diabetes prevalence differed in the three groups (P < 0.001), being 18, 17 and 31% in s-VLPD, CON and TNC, respectively. A different prevalence of cardiovascular (CV) disease was found (P < 0.001), being similar in TNC and CON (31 and 25%) and higher in s-VLPD (41%). Median follow-up during renal replacement therapy (RRT) was 36, 32 and 36 months in the three groups. Adjusted HR estimated on matched propensity patients was 0.59 (0.45-0.78) for s-VLPD versus CON. Subgroup analysis showed a lower mortality risk in s-VLPD versus matched-CON in younger patients (<70 years) and those without CV disease. No significant difference in HRs was found between s-VLPD and TNC. s-VLPD during CKD does not increase mortality in the subsequent RRT period. © The Author 2014.

During the last years the incidence of chronic kidney disease (CKD) is permanently increasing and has become a global social and economical problem in the world as well as in Poland. The aim of the study was the retrospective analysis of medical records of patients with renal failure under supervision at the outpatient clinic, Department of Nephrology, University Hospital in Cracow. The study population enclosed 1183 patients (640 men and 543 women) aged between 17 and 98 years (mean 64.7) with creatinine concentration >120 micromol/l and/or creatinine clearance <90 ml/min/1.73 m2. Hemoglobin, iron, creatinine, urea, sodium, potasium, calcium, phosphate, magnesium, PTH, uric acid, albumin, total protein, bilirubin, glucose, total cholesterol, LDL and HDL cholesterol, triglicerydes concentration and values of hematocrite, MCV, HbA1, as well as alkaline phosphatase, AspAT, AIAT activity were estimated based on standard laboratory methods. Creatinine clearances were evaluated based on 3 different methods: simplified MDRD formula, Cockcroft-Gault formula and 24-h urine collection. Mean creatinine concentration in the studied population was 172.8 micromol/l (1.95 mg/dl). Hypertension was diagnosed in 65% of patients. In spite of treatment, more than half of the patients (51.9%) have increased systolic blood pressure and above 1/3 (35%) increased diastolic blood pressure. Mean hemoglobin concentration was 13.02 g/dl; more than 12% of patients had decreased hemoglobin below 11 g/dl. Mean values of parameters discovering calcium-phosphate metabolism were: calcium--2.33 mmol/l, phosphate--1.23 mmol/l and parathormon--169.3 pg/ml. Increased value of total serum cholesterol level was noted more than half of the patients (56.5%). Significant positive correlations were found between GFR calculated based on Cockcroft-Gault formula and BMI, hemoglobin, hematocrite, serum iron, diastolic blood pressure, total and LDL serum cholesterol, triglicerydes level, as well as AIAT activity and % values of HbA1c and negative with age, serum potassium, phosphorus, PTH and uric acid.

Patient navigators and enhanced personal health records improve the quality of health care delivered in other disease states. We aimed to develop a navigator program for patients with CKD and an electronic health record-based enhanced personal health record to disseminate CKD stage-specific goals of care and education. We also conducted a pragmatic randomized clinical trial to compare the effect of a navigator program for patients with CKD with enhanced personal health record and compare their combination compared with usual care among patients with CKD stage 3b/4. Two hundred and nine patients from six outpatient clinics (in both primary care and nephrology settings) were randomized in a 2×2 factorial design into four-study groups: ( 1 ) enhanced personal health record only, ( 2 ) patient navigator only, ( 3 ) both, and ( 4 ) usual care (control) group. Primary outcome measure was the change in eGFR over a 2-year follow-up period. Secondary outcome measures included acquisition of appropriate CKD-related laboratory measures, specialty referrals, and hospitalization rates. Median age of the study population was 68 years old, and 75% were white. At study entry, 54% of patients were followed by nephrologists, and 88% were on renin-angiotensin system blockers. After a 2-year follow-up, rate of decline in eGFR was similar across the four groups ( P =0.19). Measurements of CKD-related laboratory parameters were not significantly different among the groups. Furthermore, referral for dialysis education and vascular access placement, emergency room visits, and hospitalization rates were not statistically significant different between the groups. We successfully developed a patient navigator program and an enhanced personal health record for the CKD population. However, there were no differences in eGFR decline and other outcomes among the study groups. Larger and long-term studies along with cost-effectiveness analyses are needed to evaluate the role of patient navigators and patient education through an enhanced personal health record in those with CKD.

To determine the outcome of chronic kidney disease (CKD) patients presenting for dialysis on the basis of referral to nephrologist. Observational study. Nephrology Department of King Edward Medical University/Mayo Hospital, Lahore, from January 2014 to January 2016. All patients who were presented in nephrology outpatients department and with the indication of dialysis were included in study. Patients who refused dialysis, and with acute kidney failure were excluded from the study. Proforma was designed for demographics, vital signs, volume status, and laboratory data (hemoglobin, urea, creatinine, albumin, bicarbonate etc.) of all the patients. On the basis of referral, patients were divided into two groups, i.e. early referral and late referral. Early referrals were those patients who were referred to a nephrologist more than three months before dialysis initiation. Late referrals were those patients who were referred to a nephrologist less than three months before dialysis initiation. Patients were followed up at one, three, six, and 12 months for outcome, i.e. still on dialysis or died. One hundred and seventy-six patients were enrolled in the study, and 141 were followed up to one year. Seventy- two (51.1%) patients were male, 69 (48.9%) were female and most (n=69, 48.9%) were in the middle age group. Major causes of end-stage renal disease (ESRD) were hypertension 70 (49.6%) and diabetes mellitus 66 (46.8%). Seventy-six (53.9%) patients were in fluid overload and acidotic (n=123, 87.2%). Twenty-seven (19.1%) patients were referred early and 114 (80.9%) were referred late. Overall mortality was 78 (55.3%) at one year. Factors affecting mortality were financial status and metabolic acidosis, but not referral. Temporary access for hemodialysis has 1.38 times more risk for mortality than the patients with permanent access. There is no difference on the outcome of dialysis patients on the basis referral to nephrologist. Factors affecting overall mortality in both groups were financial status, metabolic acidosis, and temporary access for dialysis. Most of the patients were referred late to the nephrologists.

The KDIGO (Kidney Disease: Improving Global Outcomes) 2012 clinical practice guideline for the management of blood pressure (BP) in chronic kidney disease (CKD) provides the structural and evidence base for the Canadian Society of Nephrology (CSN) commentary on this guideline's relevancy and application to the Canadian health care system. While in general agreement, we provide commentary on 13 of the 21 KDIGO guideline statements. Specifically, we agreed that nonpharmacological interventions should play a significant role in the management of hypertension in patients with CKD. We also agreed that the approach to the management of hypertension in elderly patients with CKD should be individualized and take into account comorbid conditions to avoid adverse outcomes from excessive BP lowering. In contrast to KDIGO, the CSN Work Group believes there is insufficient evidence to target a lower BP for nondiabetic CKD patients based on the presence and severity of albuminuria. The CSN Work Group concurs with the Canadian Hypertension Education Program (CHEP) recommendation of a target BP for all non-dialysis-dependent CKD patients without diabetes of ≤140 mm Hg systolic and ≤90 mm Hg diastolic. Similarly, it is our position that in diabetic patients with CKD and normal urinary albumin excretion, raising the threshold for treatment from <130 mm Hg systolic BP to <140 mm Hg systolic BP could increase stroke risk and the risk of worsening kidney disease. The CSN Work Group concurs with the CHEP and the Canadian Diabetic Association recommendation for diabetic patients with CKD with or without albuminuria to continue to be treated to a BP target similar to that of the overall diabetes population, aiming for BP levels < 130/80 mm Hg. Consistent with this, the CSN Work Group endorses a BP target of <130/80 mm Hg for diabetic patients with a kidney transplant. Finally, in the absence of evidence for a lower BP target, the CSN Work Group concurs with the CHEP recommendation to target BP<140/90 mm Hg for nondiabetic patients with a kidney transplant.

The aim of this study is to investigate the expression of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF) and endostatin (ES) in human peritoneum and investigate the relationship between them and peritoneum neoangiogensis in the patients with uraemia and peritoneal dialysis (PD). Peritoneal biopsies were obtained from normal subjects (n = 8), uraemic predialysis patients (n = 12) and PD patients (n = 10). The mRNA expression of VEGF, bFGF and ES in peritoneal tissues were measured through real-time polymerase chain reaction. The protein expression of VEGF, bFGF and ES in peritoneal tissues were determined through western blot. Microvessel density (MVD) of peritoneal tissue was assessed using immunohistochemistry with CD34 monoclonal antibody. The mRNA and protein of VEGF, bFGF and ES were expressed in all peritoneal samples. Compared with the normal control group, the mRNA and protein expression of VEGF and bFGF in peritoneal tissues were all significantly upregulated in the uraemic predialysis and PD group (all P < 0.05). Compared with the normal control group, the protein expression of ES were significantly upregulated in the uraemic predialysis and PD group (all (P < 0.05), but the mRNA expression of ES did not have obvious differences in the uraemic predialysis and PD group as compared to the normal control group (P > 0.05). MVD of peritoneal tissue were increased in the uraemic predialysis and PD group compared with the normal group (all P < 0.05). A significant positive correlation was found between VEGF mRNA expression and MVD, bFGF mRNA expression and MVD. The mRNA expression of VEGF and bFGF, the protein expression of VEGF, bFGF, and ES and microvessel density (MVD) are increased both in the uraemic predialysis and PD patients. These results show that uraemia circumstances and non-physiological compatibility of peritoneal dialysis solution might increase VEGF, bFGF and ES expression and MVD, which might participate in the increment of the peritoneum neoangiogensis and ultrafiltration failure in PD patients. © 2011 The Authors.

The British Association for Paediatric Nephrology Registry (BAPN) was established to analyse data related to renal replacement therapy (RRT) in children. The registry receives data from the 13 paediatric nephrology centres in the UK. This chapter aims to provide centre specific data so that individual centres can reflect on the contribution that their data makes to the national picture and to determine the extent to which their patient parameters meet nationally agreed audit standards for the management of children with established renal failure (ERF). Data returns included a mixture of electronic (92%) and paper (8%) returns. Data were analysed to calculate summary statistics and where applicable the percentage achieving an audit standard. The standards used were those set out by the Renal Association and the National Institute for Health and Clinical Excellence. Anthropometric data confirmed that children receiving RRT were short compared to healthy peers. Amongst patients with a height of <2SD between 2001 and 2012, 29.2%were receiving growth hormone if they were on dialysis compared to 11.9% if they had a functioning transplant. Prevalence rates of overweight and obese status in children with ERF remain concerningly high. Blood pressure control remained challenging with wide inter-centre variation although this was significantly better in children with a functioning transplant. Over a quarter of haemodialysis patients and 17.3% of peritoneal dialysis patients were anaemic, compared to only 8.3% of transplanted patients. ESA use in the dialysis population exceeded 90% amongst anaemic patients. The control of renal bone disease remained challenging. Optimising growth and reducing prevalent excess weight in children on RRT remains challenging. The likelihood of complete electronic reporting in the near future with plans for quarterly reporting in the format of the recently finalised NEW paediatric dataset will hopefully improve quality of data and their reporting, allowing improvements in patient care. © 2014 S.

Joint modelling of repeated measurement and time-to-event data: an introductory tutorial.

PubMed

Asar, Özgür; Ritchie, James; Kalra, Philip A; Diggle, Peter J

2015-02-01

The term 'joint modelling' is used in the statistical literature to refer to methods for simultaneously analysing longitudinal measurement outcomes, also called repeated measurement data, and time-to-event outcomes, also called survival data. A typical example from nephrology is a study in which the data from each participant consist of repeated estimated glomerular filtration rate (eGFR) measurements and time to initiation of renal replacement therapy (RRT). Joint models typically combine linear mixed effects models for repeated measurements and Cox models for censored survival outcomes. Our aim in this paper is to present an introductory tutorial on joint modelling methods, with a case study in nephrology. We describe the development of the joint modelling framework and compare the results with those obtained by the more widely used approaches of conducting separate analyses of the repeated measurements and survival times based on a linear mixed effects model and a Cox model, respectively. Our case study concerns a data set from the Chronic Renal Insufficiency Standards Implementation Study (CRISIS). We also provide details of our open-source software implementation to allow others to replicate and/or modify our analysis. The results for the conventional linear mixed effects model and the longitudinal component of the joint models were found to be similar. However, there were considerable differences between the results for the Cox model with time-varying covariate and the time-to-event component of the joint model. For example, the relationship between kidney function as measured by eGFR and the hazard for initiation of RRT was significantly underestimated by the Cox model that treats eGFR as a time-varying covariate, because the Cox model does not take measurement error in eGFR into account. Joint models should be preferred for simultaneous analyses of repeated measurement and survival data, especially when the former is measured with error and the association between the underlying error-free measurement process and the hazard for survival is of scientific interest. © The Author 2015; all rights reserved.

Nocturnal enuresis (NE) is a very common pediatric disorder. The aim of this study was to evaluate the characteristics of patients with NE or urinary incontinence (UI) during a period of 5 years to increase the knowledge on these conditions and optimize their diagnosis and treatment. We enrolled 278 children with NE or UI referred to the pediatric nephrology ambulatory, 'A. Gemelli' University Hospital of Rome, from December 2006 to December 2011. We observed that heredity, parasomnias, left-handedness, polythelia and constipation are correlated to NE and UI. We wanted to clarify the definition of NE and UI and describe our experience on the main characteristics of these conditions by referring to the latest knowledge reported in the literature. 2013 S.

2016-12-07

Paraprotein-related kidney disease represents a complex group of diseases caused by an abnormal paraprotein secreted by a clone of B cells. The disease manifestations range from tubulopathies, such as the Fanconi syndrome, to a spectrum of glomerular diseases that can present with varying degrees of proteinuria and renal dysfunction. Diagnosis of these diseases can be challenging because of the wide range of manifestations as well as the relatively common finding of a serum paraprotein, especially in elderly patients. Thus, renal biopsy along with detailed hematologic workup is essential to link the presence of the paraprotein to the associated renal disease. Recent advances in treatment with more effective and targeted chemotherapies, as well as stem cell transplantation, have improved the renal and overall prognosis for many of these disorders.

Bicarbonate Balance and Prescription in ESRD.

PubMed

Abramowitz, Matthew K

2017-03-01

The optimal approach to managing acid-base balance is less well defined for patients receiving hemodialysis than for those receiving peritoneal dialysis. Interventional studies in hemodialysis have been limited and inconsistent in their findings, whereas more compelling data are available from interventional studies in peritoneal dialysis. Both high and low serum bicarbonate levels associate with an increased risk of mortality in patients receiving hemodialysis, but high values are a marker for poor nutrition and comorbidity and are often highly variable from month to month. Measurement of pH would likely provide useful additional data. Concern has arisen regarding high-bicarbonate dialysate and dialysis-induced alkalemia, but whether these truly cause harm remains to be determined. The available evidence is insufficient for determining the optimal target for therapy at this time. Copyright © 2017 by the American Society of Nephrology.

2017-01-01

Executive leaders of an acute care hospital performed a market and financial analysis, and created a business plan to establish an inpatient hemodialysis unit operated by the hospital to provide safe, high-quality, evidence-based care to the population of individuals experiencing end stage renal disease (ESRD) within the community. The business plan included a SWOT (Strengths - Weaknesses - Opportunities - Threats) analysis to assess advantages of the hospital providing inpatient hemodialysis services versus outsourcing the services with a contracted agency. The results of the project were a newly constructed tandem hemodialysis room and an operational plan with clearly defined key performance indicators, process improvement initiatives, and financial goals. This article provides an overview of essential components of a business plan to guide the establishment of an inpatient hemodialysis unit. Copyright© by the American Nephrology Nurses Association.

A Communication Framework for Dialysis Decision-Making for Frail Elderly Patients

PubMed Central

Cohen, Robert A.

2014-01-01

Frail elderly patients with advanced kidney disease experience many of the burdens associated with dialysis. Although these patients constitute the fastest-growing population starting dialysis, they often suffer loss of functional status, impaired quality of life, and increased mortality after dialysis initiation. Nephrology clinicians face the challenges of helping patients decide if the potential benefits of dialysis outweigh the risks and preparing such patients for future setbacks. A communication framework for dialysis decision-making that aligns treatment choices with patient goals and values is presented. The role of uncertainty is highlighted, and the concept of a goal-directed care plan is introduced. This plan incorporates a time-limited trial that promotes frequent opportunities for reassessment. Using the communication skills presented, the clinician can prepare and guide patients for the dialysis trajectory as it unfolds. PMID:24970868

Nephrourologic malformations in Turner syndrome are frequent, its diagnosis and follow-up is important in order to diminish the morbidity of this disease. The aim of this retrospective study was to analyze the nephrourologic pathology in 72 girls with Turner syndrome followed between 1989 and 2008 at Garrahan Hospital. The prevalence of nephrourologic involvement was 33% (24 patients). The most frequent findings were urinary system malformations, isolated (10 pacientes, 42%) or associated with renal malformations (9 patients, 37%); 5 patients (21%) had only renal malformations. Fifty percent of patients developed complications (8 urinary tract infection, 2 proteinuria and 2 arterial hypertension); however, none progressed to chronic renal failure. The prevalence of nephrourologic involvement was 33% and a half of these girls developed complications, our findings show the need of routine nephrological follow-up of girls with Turner syndrome and nephrourologic malformations.

The coming fiscal crisis: nephrology in the line of fire.

PubMed

Andersen, Martin J; Friedman, Allon N

2013-07-01

Nephrologists in the United States face a very uncertain economic future. The astronomical federal debt and unfunded liability burden of Medicare combined with the aging population will place unprecedented strain on the health care sector. To address these fundamental problems, it is conceivable that the federal government will ultimately institute rationing and other budget-cutting measures to rein in costs of ESRD care, which is generously funded relative to other chronic illnesses. Therefore, nephrologists should expect implementation of cost-cutting measures, such age-based rationing, mandated delayed dialysis and home therapies, compensated organ donation, and a shift in research priorities from the dialysis to the predialysis patient population. Nephrologists also need to recognize that these changes, which are geared toward the population level, may make it more difficult to advocate effectively for the needs of individual patients.

PathoSpotter-K: A computational tool for the automatic identification of glomerular lesions in histological images of kidneys

PathoSpotter is a computational system designed to assist pathologists in teaching about and researching kidney diseases. PathoSpotter-K is the version that was developed to detect nephrological lesions in digital images of kidneys. Here, we present the results obtained using the first version of PathoSpotter-K, which uses classical image processing and pattern recognition methods to detect proliferative glomerular lesions with an accuracy of 88.3 ± 3.6%. Such performance is only achieved by similar systems if they use images of cell in contexts that are much less complex than the glomerular structure. The results indicate that the approach can be applied to the development of systems designed to train pathology students and to assist pathologists in determining large-scale clinicopathological correlations in morphological research.

Auto-immun events are rare in multiple myeloma (MM). Here, we report one MM case complicated by Evans syndrome (Autoimmun hemolytic anemia (AIHA) associated with thrombocytopenia). A 52-year-old man was admitted in nephrology department with severe anemia, renal insufficiency and hypergamma globulinemia. Laboratory exams showed acute hemolysis due to an IgG warm autoantibody. Serum electrophoresis revealed the presence of a monoclonal IgG protein and urinary M protein was 2g/day. A whole body CT-Scan showed osteolytic lesions of vertebral body of C5, D4, L3, L4 and the left iliac wing. The diagnosis of multiple myeloma and Evan's syndrome was made, we underwent chemotherapy by BTD (bortezomib-thalidomide-dexamethasone) and continuous corticosteroid therapy but unfortunately the patient died secondary of a Lactic acidosis. The relationship between MM and hemolysis remain unclear. PMID:28292089

2010-03-01

Loin pain haematuria syndrome is a common problem with complications including opiate dependence. Morbidity treatments include intra-ureteric capsaicin infusion, nephrectomy, autotransplantation and nephrolysis. We explored the use of flexible cystoscopic infusion of intra-ureteric bupivicaine. Patients presenting with chronic loin pain underwent urological and nephrological evaluation. Bupivicaine (0.5%, 20 ml) was infused via an intra-ureteric catheter under flexible cystoscopic guidance. Repeat infusions were offered if indicated. Sixteen of 17 patients with 1-year follow-up responded and were satisfied. Twelve of these required repeat infusions (mean, 2.9 infusions). The procedures were well tolerated by all patients without adverse effects. Intra-ureteric bupivicaine infusion has a place in the management of patients with chronic renal pain. It offers a minimally invasive alternative to other treatments. This procedure warrants further investigation within a randomised, controlled trial setting.

2013-01-01

Fatigue is a common and debilitating symptom for adult patients with end stage renal disease on hemodialysis and has been associated with decreased survival and quality of life. Patients on hemodialysis must find ways to manage their fatigue and mitigate its effects on their lives. Currently, there is no description of the experience of fatigue for patients on hemodialysis living in the U.S., nor is there any description of the ways in which they manage their fatigue. The purpose of this qualitative descriptive work was to describe the experience and self-management of fatigue. Several themes were identified which included: the nature of fatigue, management of fatigue, consequences of fatigue, and factors associated with fatigue. This information will be valuable to nephrology nurses as they continue to care for and educate patients on hemodialysis. PMID:23767335

Evaluation of Kidney Donors: Core Curriculum 2018.

Nearly 100,000 patients are waiting for a kidney transplant, yet each year only 11,000 undergo transplantation with a deceased donor kidney. Annual death rates among waitlist registrants range from 5% to 15%; many die before receiving a transplant. Not surprisingly, registrants turn to family and friends to become living kidney donors on their behalf. Living kidney donor selection practices aim to quantify lifetime risk for kidney failure based on a candidate's predonation demographic and health characteristics. It has been established that estimated lifetime risk for kidney failure varies considerably based on predonation comorbid conditions, and as such, it is of paramount importance that potential living donor candidates undergo proper medical, surgical, and psychosocial screening before donation. This installment of AJKD's Core Curriculum in Nephrology provides readers with the tools necessary for proper evaluation of living kidney donor candidates.

2016-01-01

Transcatheter aortic valve replacement (TAVR) has now emerged as a viable treatment option for high-risk patients with severe aortic stenosis (AS) who are not suitable candidates for surgical aortic valve replacement (SAVR). Despite encouraging published outcomes, acute kidney injury (AKI) is common and lowers the survival of patients after TAVR. The pathogenesis of AKI after TAVR is multifactorial including TAVR specific factors such as the use of contrast agents, hypotension during rapid pacing, and embolization; preventive measures may include pre-procedural hydration, limitation of contrast dye exposure, and avoidance of intraprocedural hypotension. In recent years, the number of TAVR performed worldwide has been increasing, as well as published data on renal perspectives of TAVR including AKI, chronic kidney disease, end-stage kidney disease, and kidney transplantation. This review aims to present the current literature on the nephrology aspects of TAVR, ultimately to improve the patients’ quality of care and outcomes. PMID:27069960

Five policies to promote palliative care for patients with ESRD.

2013-10-01

Patients with ESRD experience complex and costly care that does not always meet their needs. Palliative care, which focuses on improving quality of life and relieving suffering for patients with serious illnesses, could address a large unmet need among patients with ESRD. Strengthening palliative care is a top policy priority for health reform efforts based on strong evidence that palliative care improves value. This commentary outlines palliative care policies for patients with ESRD and is directed at policymakers, dialysis providers, nephrology professional societies, accreditation organizations, and funding agencies who play a key role in the delivery and determination of quality of ESRD care. Herein we suggest policies to promote palliative care for patients with ESRD by addressing key barriers, including the lack of access to palliative care, lack of capacity to deliver palliative care, and a limited evidence base. We also provide examples of how these policies could be implemented within the existing ESRD care infrastructure.

2002-06-01

AA amyloidosis is a relatively rare disease which complicates chronic inflammatory diseases, chronic infections, familial Mediterranean fever (FMF) and malignant diseases. Although amyloid deposition may be found in many organs, renal involvement dominates the clinical picture. We reviewed 63 patients with AA amyloidosis who presented to our nephrology department between 1995 and 2000. Prognostic markers, detailed history, physical examination and laboratory tests were evaluated. The causes of AA amyloidosis were as follows: FMF 42 (66.6%), pulmonary tuberculosis 9 (14.2%), chronic osteomyelitis 4 (6.3%), bronchiectasia 4 (6.3%), rheumatoid arthritis 1 (1.5%), juvenile idiopathic arthritis 1 (1.5%), inflammatory abdominal aortic aneurysm 1 (1.5 %), unknown aetiology 1 (1.5%). The diagnosis was made on renal biopsies in 63.4% of the patients, while the remaining 36.6% were diagnosed as a result of rectal biopsies. Sixteen patients died. A low serum albumin, high creatinine and high 24-hour urine albumin excretion were associated with high mortality.

A cross-sectional, descriptive study was conducted among Dutch kidney transplant recipients to investigate travel health knowledge, attitudes and practices while staying abroad. A total of 290 individuals visiting the nephrology outpatient clinic completed the questionnaires. Thirty four percent of the responders had traveled outside Western Europe (WE) and Northern America (NA); 22% of these travelers did not seek pre-travel health advice. Transplant physicians were most frequently consulted for pre-travel advice (53%). Of the responders traveling outside WE and NA 29% were ill during their most recent journey. Diabetic transplant recipients were at the highest risk. Four of seventeen ill recipients (24%) were hospitalized, reflecting the high morbidity of travel-related disease in this patient group. Our data show that there is need for improvement of pre-travel healthcare, and suggest an important role for transplant physicians in providing adequate counseling.

Evidence suggests that management of advanced chronic kidney disease affects patient outcomes. To identify clinical areas that demand attention from a quality improvement perspective, we sought to examine the extent of conformance to an advanced chronic kidney disease guideline in a range of practices. A total of 237 patient medical records were abstracted from 4 primary care providers and 4 nephrology private practices across the country. In the practices studied, management of advanced chronic kidney disease patients was suboptimal for patients managed by primary care providers as well as those managed by nephrologists (overall conformance 27% and 42%, respectively), specifically for anemia, bone disease, and timing for renal replacement therapy. The current exercise (in conjunction with a literature search and focused and individual interviews with providers and patients) offered valuable information that was used to develop a toolkit for optimizing management of advanced chronic kidney disease.

Mutations in the genes COL4A3, COL4A4, and COL4A5 affect the synthesis, assembly, deposition, or function of the collagen IV α345 molecule, the major collagenous constituent of the mature mammalian glomerular basement membrane. These mutations are associated with a spectrum of nephropathy, from microscopic hematuria to progressive renal disease leading to ESRD, and with extrarenal manifestations such as sensorineural deafness and ocular anomalies. The existing nomenclature for these conditions is confusing and can delay institution of appropriate nephroprotective therapy. Herein we propose a new classification of genetic disorders of the collagen IV α345 molecule with the goal of improving renal outcomes through regular monitoring and early treatment.

From bench to pet shop to bedside? The environment and immune function in mice.

Kitching, A Richard; Ooi, Joshua D

2016-12-01

The generation of inbred mouse strains in the late 19th and early 20th centuries, coupled with the later establishment of specific pathogen-free animal research facilities created a powerful biological platform for exploration of the immune system in health and disease. Studies in this setting have been responsible for huge advances in our understanding of immunobiology and disease, including immune-mediated kidney disease. However, whereas this reductionist and relatively standardized approach allows us to make sense of complex disease biology, it takes place in controlled environments that clearly differ from those that we humans encounter in everyday life. Recent studies comparing the immune systems of wild mice, pet shop mice, and laboratory mice suggest ways in which the murine immune system can be influenced to behave more like the human immune system.

The role of the renal specialist nurse in prevention of renal failure.

PubMed

Hurst, J

2002-01-01

This article will investigate the care required for those with reduced renal function before renal replacement therapy (RRT) commences. Renal nurses are often involved with the technical, monitoring and evaluative aspects of RRT for those with end stage renal failure. However, many patients may experience reduced renal function many years before reaching the stage of needing RRT. Renal nurses are already involved in the preparation of patients for RRT, but are not presently exercising their specialist skills in the period before this time by contributing to the prevention of end stage renal failure (ESRF). Screening programmes carried out in various parts of the world demonstrate that many members of the population have undetected renal insufficiency, and may benefit from intervention from the nephrology team to prevent further renal dysfunction. It is for this group of patients that this article will consider the potential for the renal nurse to expand their scope of practice.

In both atypical hemolytic uremic syndrome (aHUS) and C3 glomerulopathy (C3G) complement plays a primary role in disease pathogenesis. Herein we report the outcome of a 2015 Kidney Disease: Improving Global Outcomes (KDIGO) Controversies Conference where key issues in the management of these 2 diseases were considered by a global panel of experts. Areas addressed included renal pathology, clinical phenotype and assessment, genetic drivers of disease, acquired drivers of disease, and treatment strategies. In order to help guide clinicians who are caring for such patients, recommendations for best treatment strategies were discussed at length, providing the evidence base underpinning current treatment options. Knowledge gaps were identified and a prioritized research agenda was proposed to resolve outstanding controversial issues. Copyright © 2016 International Society of Nephrology.

Novel Insights into the Pathogenesis of Monogenic Congenital Anomalies of the Kidney and Urinary Tract.

van der Ven, Amelie T; Vivante, Asaf; Hildebrandt, Friedhelm

2018-01-01

Congenital anomalies of the kidneys and urinary tract (CAKUT) comprise a large spectrum of congenital malformations ranging from severe manifestations, such as renal agenesis, to potentially milder conditions, such as vesicoureteral reflux. CAKUT causes approximately 40% of ESRD that manifests within the first three decades of life. Several lines of evidence indicate that CAKUT is often caused by recessive or dominant mutations in single (monogenic) genes. To date, approximately 40 monogenic genes are known to cause CAKUT if mutated, explaining 5%-20% of patients. However, hundreds of different monogenic CAKUT genes probably exist. The discovery of novel CAKUT-causing genes remains challenging because of this pronounced heterogeneity, variable expressivity, and incomplete penetrance. We here give an overview of known genetic causes for human CAKUT and shed light on distinct renal morphogenetic pathways that were identified as relevant for CAKUT in mice and humans.

2016-06-01

The "choosing wisely" recommendations of the German Society of Internal Medicine (DGIM) and its specialist societies address diagnostic and therapeutic procedures, which are of particular medical importance but applied too often or too rarely in clinical practice. The aim is to further improve treatment of patients. Important topics of overuse and insufficient treatment related to the diagnostics, therapy, prevention and exclusion of infectious diseases could be identified. These topics not only play an important role in the discipline of infectious diseases but are also relevant for other internal medical disciplines. These topics related to infectious diseases have also been integrated into the recommendations of the German Society of Gastroenterology, Digestive and Metabolic Diseases as well as the German Societies for Internal Intensive Care and Emergency Medicine, for Pneumology, for Nephrology and for Rheumatology. The pivotal issues of the recommendations are the inappropriate use of antibiotics and insufficient vaccination rates.

This study has been performed in the Nephrology and Dialysis Unit, in Desio Hospital, Italy. The aim of this study is to evaluate, starting from research questions, which information is given to patient in the pre-dialysis colloquia for his/her chosen dialysis methods. Moreover, the study evaluated feelings, emotions and fears since the announcement of the necessity of dialysis treatment. The objective of the study was reached through the interview with patients on dialysis. The fact-finding survey was based on the tools of social research, as the semi-structured interview. Instead of using the questionnaire, even though it make it easier to collect larger set of data, the Authors decided to interview patients in person, since the interview allows direct patient contact and to build a relationship of trust with the interviewer, in order to allow patient explain better his/her feeling.

Four-Dimensional Imaging of T Cells in Kidney Transplant Rejection.

PubMed

Hughes, Andrew D; Lakkis, Fadi G; Oberbarnscheidt, Martin H

2018-06-01

Kidney transplantation is the treatment of choice for ESRD but is complicated by the response of the recipient's immune system to nonself histocompatibility antigens on the graft, resulting in rejection. Multiphoton intravital microscopy, referred to as four-dimensional imaging because it records dynamic events in three-dimensional tissue volumes, has emerged as a powerful tool to study immunologic processes in living animals. Here, we will review advances in understanding the complex mechanisms of T cell-mediated rejection made possible by four-dimensional imaging of mouse renal allografts. We will summarize recent data showing that activated (effector) T cell migration to the graft is driven by cognate antigen presented by dendritic cells that surround and penetrate peritubular capillaries, and that T cell-dendritic cell interactions persist in the graft over time, maintaining the immune response in the tissue.

The first three chapters consider measurement of mercury renal uptake by external counting, by quantitative scintigraphy, and by the gamma camera. Some topics discussed in the remaining 14 chapters are as follows: renal depth; phantoms; precautions regarding the liver, spleen, and intestine; stability of /sup 197/HgCl/sub 2/ solutions; use of mercury renal uptake in pediatric and adult urology; indications for mercury renal uptake in renal transplants; and appraisal of the radiological and chemical toxicity of /sup 197/HgCl/sub 2/. It was concluded that mercury renal uptake is an accurate and nontraumatizing method of measuring the functional value of each kidney. Itmore » makes it possible to determine whether a kidney is normal or pathological and to what extent its function is diminished or increased. (HLW)« less

New Insights into Dialysis Vascular Access: What Is the Optimal Vascular Access Type and Timing of Access Creation in CKD and Dialysis Patients?

PubMed

Woo, Karen; Lok, Charmaine E

2016-08-08

Optimal vascular access planning begins when the patient is in the predialysis stages of CKD. The choice of optimal vascular access for an individual patient and determining timing of access creation are dependent on a multitude of factors that can vary widely with each patient, including demographics, comorbidities, anatomy, and personal preferences. It is important to consider every patient's ESRD life plan (hence, their overall dialysis access life plan for every vascular access creation or placement). Optimal access type and timing of access creation are also influenced by factors external to the patient, such as surgeon experience and processes of care. In this review, we will discuss the key determinants in optimal access type and timing of access creation for upper extremity arteriovenous fistulas and grafts.

Papez, Karen E; Barletta, Gina-Marie; Hsieh, Stephanie; Joseph, Mark; Morgenstern, Bruce Z

2013-12-01

Accurate knowledge of glomerular filtration rate (GFR) is essential to the practice of nephrology. Routine surveillance of GFR is most commonly executed using estimated GFR (eGFR) calculations, most often from serum creatinine measurements. However, cystatin C-based equations have demonstrated earlier sensitivity to decline in renal function. The literature regarding eGFR from cystatin C has few references that include transplant recipients. Additionally, for most of the published eGFR equations, patients of Hispanic ethnicity have not been enrolled in sufficient numbers. The applicability of several eGFR equations to the pediatric kidney transplant population at our center were compared in the context of determining whether Hispanic ethnicity was associated with equation performance. Updated Schwartz, CKiD, and Zappitelli eGFR estimation equations demonstrated the highest correlations. The authors recommend further prospective investigations to validate and identify factors contributing to these findings.

2016-07-01

Using a cross-sectional design, we examined coping stages (Kübler-Ross) among patients with end-stage renal disease at nephrology practices incorporating professional social workers as patient navigators, providing person-centered education and support (N = 420). We evaluated associations with behavioral counseling constructs (assess-advise-agree-assist-arrange). Coping stages comprised denial = 35.24 percent, acceptance = 24.05 percent, depression = 21.43 percent, bargaining = 12.86 percent, and anger = 6.43 percent. Compared to denial, other coping stages showed increased odds ratios for transplant referral agreement, transplant referral evaluations, understanding treatments, understanding donation procedures, plans to recruit donors, active donor recruitment, and potential living donor(s). Assessment of coping stages, and strategies to influence these, may be key factors in guiding patients to living donor kidney transplantation. © The Author(s) 2014.

Renal potassium physiology: integration of the renal response to dietary potassium depletion.

Kamel, Kamel S; Schreiber, Martin; Halperin, Mitchell L

2018-01-01

We summarize the current understanding of the physiology of the renal handling of potassium (K + ), and present an integrative view of the renal response to K + depletion caused by dietary K + restriction. This renal response involves contributions from different nephron segments, and aims to diminish the rate of excretion of K + as a result of: decreasing the rate of electrogenic (and increasing the rate of electroneutral) reabsorption of sodium in the aldosterone-sensitive distal nephron (ASDN), decreasing the abundance of renal outer medullary K + channels in the luminal membrane of principal cells in the ASDN, decreasing the flow rate in the ASDN, and increasing the reabsorption of K + in the cortical and medullary collecting ducts. The implications of this physiology for the association between K + depletion and hypertension, and K + depletion and formation of calcium kidney stones are discussed.

Quality Measures for Dialysis: Time for a Balanced Scorecard

PubMed Central

2016-01-01

Recent federal legislation establishes a merit-based incentive payment system for physicians, with a scorecard for each professional. The Centers for Medicare and Medicaid Services evaluate quality of care with clinical performance measures and have used these metrics for public reporting and payment to dialysis facilities. Similar metrics may be used for the future merit-based incentive payment system. In nephrology, most clinical performance measures measure processes and intermediate outcomes of care. These metrics were developed from population studies of best practice and do not identify opportunities for individualizing care on the basis of patient characteristics and individual goals of treatment. The In-Center Hemodialysis (ICH) Consumer Assessment of Healthcare Providers and Systems (CAHPS) survey examines patients' perception of care and has entered the arena to evaluate quality of care. A balanced scorecard of quality performance should include three elements: population-based best clinical practice, patient perceptions, and individually crafted patient goals of care. PMID:26316622

The rate and factors that influence progression of chronic kidney disease (CKD) in developing countries like India are unknown. A pan-country prospective, observational cohort study is needed to address these knowledge gaps. The Indian Chronic Kidney Disease (ICKD) study will be a cohort study of approximately 5000 patients with mild to moderate CKD presenting to centres that represent different geographical regions in India. Time to 50% decline in baseline estimated glomerular filtration rate, need of renal replacement therapy or any new cardiovascular disease (CVD) event or death from CVD are the primary end points. This study will provide the opportunity to determine risk factors for CKD progression and development of CVD in Indian subjects and perform international comparisons to determine ethnic and geographical differences. A bio-repository will provide a chance to discover biomarkers and explore genetic risk factors. © 2016 Asian Pacific Society of Nephrology.

Ureteric bupivicaine infusion for loin pain haematuria syndrome

2010-01-01

INTRODUCTION Loin pain haematuria syndrome is a common problem with complications including opiate dependence. Morbidity treatments include intra-ureteric capsaicin infusion, nephrectomy, autotransplantation and nephrolysis. We explored the use of flexible cystoscopic infusion of intra-ureteric bupivicaine. PATIENTS AND METHODS Patients presenting with chronic loin pain underwent urological and nephrological evaluation. Bupivicaine (0.5%, 20 ml) was infused via an intra-ureteric catheter under flexible cystoscopic guidance. Repeat infusions were offered if indicated. RESULTS Sixteen of 17 patients with 1-year follow-up responded and were satisfied. Twelve of these required repeat infusions (mean, 2.9 infusions). The procedures were well tolerated by all patients without adverse effects. CONCLUSIONS Intra-ureteric bupivicaine infusion has a place in the management of patients with chronic renal pain. It offers a minimally invasive alternative to other treatments. This procedure warrants further investigation within a randomised, controlled trial setting. PMID:20353642

Randomized controlled trials (RCTs) are considered the gold standard study design to investigate the effect of health interventions, including treatment. However, in some situations, it may be unnecessary, inappropriate, impossible, or inadequate to perform an RCT. In these special situations, well-designed observational studies, including cohort and case-control studies, may provide an alternative to doing nothing in order to obtain estimates of treatment effect. It should be noted that such studies should be performed with caution and correctly. The aims of this review are (1) to explain why RCTs are considered the optimal study design to evaluate treatment effects, (2) to describe the situations in which an RCT is not possible and observational studies are an adequate alternative, and (3) to explain when randomization is not needed and can be approximated in observational studies. Examples from the nephrology literature are used for illustration. Copyright 2009 S. Karger AG, Basel.

2017-01-01

A patient-centered quality improvement program implemented in one Virginia hemodialysis facility sought to determine if peer-to-peer (P2P) programs can assist patients on in-center hemodialysis with self-management and improve outcomes. Using a single-arm, repeatedmeasurement, quasi-experimental design, 46 patients participated in a four-month P2P intervention. Outcomes include knowledge, self-management behaviors, and psychosocial health indicators: self-efficacy, perceived social support, hemodialysis social support, and healthrelated quality of life (HRQoL). Physiological health indicators included missed and shortened treatments, arteriovenous fistula placement, interdialytic weight gain, serum phosphorus, and hospitalizations. Mentees demonstrated increased knowledge, self-efficacy, perceived social support, hemodialysis social support, and HRQoL. Missed treatments decreased. Mentors experienced increases in knowledge, self-management, and social support. A P2P mentoring program for in-center hemodialysis can benefit both mentees and mentors.

Renal failure is common in patients with severe heart failure. This complex pathophysiological interaction has been classified as cardio-renal syndrome. In these patients hydropic decompensation is the main cause of hospitalization. In patients with refractory heart failure, characterized by diuretic resistance and congestion due to volume overload, ultrafiltration has to be considered. In acute decompensated heart failure with worsening of renal function, extracorporeal ultrafiltration is the preferred treatment modality. On the other hand, patients suffering from chronic decompensated heart failure, particularly patients with ascites, will profit from the treatment specific advantages of peritoneal ultrafiltration. Prerequisite for an optimized care of patients with cardio-renal syndrome is the close collaboration among intensive care doctors, cardiologists and nephrologists. © Georg Thieme Verlag KG Stuttgart · New York.

The growth of palliative care in the United States.

PubMed

Hughes, Mark T; Smith, Thomas J

2014-01-01

Palliative care has been one of the most rapidly growing fields of health care in the United States in the past decade. The benefits of palliative care have now been shown in multiple clinical trials, with increased patient and provider satisfaction, equal or better symptom control, more discernment of and honoring choices about place of death, fewer and less intensive hospital admissions in the last month of life, less anxiety and depression, less caregiver distress, and cost savings. The cost savings come from cost avoidance, or movement of a patient from a high cost setting to a lower cost setting. Barriers to expanded use include physician resistance, unrealistic expectations of patients and families, and lack of workforce. The future of palliative care includes more penetration into other fields such as nephrology, neurology, and surgery; further discernment of the most effective and cost-effective models; and establishment of more outpatient services.

Psychiatric patients' coping capacity with various life situations is limited due to their mental illness. This difficulty is even more pronounced when dealing with severe physical conditions such as kidney failure, the need for dialysis and kidney transplant. In the past, similar to patients who suffered from additional physical conditions, patients with major psychiatric disorders, long-term psychotic illness such as schizophrenia, were not considered candidates for dialysis treatment. Although these attitudes have changed, there is still concern that psychiatric patients would find it difficult to cooperate with the long-term treatment required following kidney transplant, and that lack of careful adherence to medication regimens could lead to rejection of the implant. This article describes five mentally ill individuals who suffer from terminal kidney failure, and illustrates the dilemma associated with dialysis and kidney transplant in psychiatric patients. Close cooperation between the psychiatric staff and the nephrology team can lead to the hoped for outcomes.

Kidney transplantation (KT) is often considered to be the method best able to restore fertility in a woman with chronic kidney disease (CKD). However, pregnancies in KT are not devoid of risks (in particular prematurity, small for gestational age babies, and the hypertensive disorders of pregnancy). An ideal profile of the potential KT mother includes "normal" or "good" kidney function (usually defined as glomerular filtration rate, GFR ≥ 60 ml/min), scant or no proteinuria (usually defined as below 500 mg/dl), normal or well controlled blood pressure (one drug only and no sign of end-organ damage), no recent acute rejection, good compliance and low-dose immunosuppression, without the use of potentially teratogen drugs (mycophenolic acid and m-Tor inhibitors) and an interval of at least 1-2 years after transplantation. In this setting, there is little if any risk of worsening of the kidney function. Less is known about how to manage "non-ideal" situations, such as a pregnancy a short time after KT, or one in the context of hypertension or a failing kidney. The aim of this position statement by the Kidney and Pregnancy Group of the Italian Society of Nephrology is to review the literature and discuss what is known about the clinical management of CKD after KT, with particular attention to women who start a pregnancy in non-ideal conditions. While the experience in such cases is limited, the risks of worsening the renal function are probably higher in cases with markedly reduced kidney function, and in the presence of proteinuria. Well-controlled hypertension alone seems less relevant for outcomes, even if its effect is probably multiplicative if combined with low GFR and proteinuria. As in other settings of kidney disease, superimposed preeclampsia (PE) is differently defined and this impairs calculating its real incidence. No specific difference between non-teratogen immunosuppressive drugs has been shown, but calcineurin inhibitors have been associated with foetal growth restriction and low birth weight. The clinical choices in cases at high risk for malformations or kidney function impairment (pregnancies under mycophenolic acid or with severe kidney-function impairment) require merging clinical and ethical approaches in which, beside the mother and child dyad, the grafted kidney is a crucial "third element".

Gaining the PROMIS perspective from children with nephrotic syndrome: a Midwest pediatric nephrology consortium study

PubMed Central

2013-01-01

Background and objectives Nephrotic syndrome (NS) represents a common disease in pediatric nephrology typified by a relapsing and remitting course and characterized by the presence of edema that can significantly affect the health-related quality of life in children and adolescents. The PROMIS pediatric measures were constructed to be publically available, efficient, precise, and valid across a variety of diseases to assess patient reports of symptoms and quality of life. This study was designed to evaluate the ability of children and adolescents with NS to complete the PROMIS assessment via computer and to initiate validity assessments of the short forms and full item banks in pediatric NS. Successful measurement of patient reported outcomes will contribute to our understanding of the impact of NS on children and adolescents. Design This cross-sectional study included 151 children and adolescents 8-17 years old with NS from 16 participating institutions in North America. The children completed the PROMIS pediatric depression, anxiety, social-peer relationships, pain interference, fatigue, mobility and upper extremity functioning measures using a web-based interface. Responses were compared between patients experiencing active NS (n = 53) defined by the presence of edema and patients with inactive NS (n = 96) defined by the absence of edema. Results All 151 children and adolescents were successfully able to complete the PROMIS assessment via computer. As hypothesized, the children and adolescents with active NS were significantly different on 4 self-reported measures (anxiety, pain interference, fatigue, and mobility). Depression, peer relationships, and upper extremity functioning were not different between children with active vs. inactive NS. Multivariate analysis showed that the PROMIS instruments remained sensitive to NS disease activity after adjusting for demographic characteristics. Conclusions Children and adolescents with NS were able to successfully complete the PROMIS instrument using a web-based interface. The computer based pediatric PROMIS measurement effectively discriminated between children and adolescents with active and inactive NS. The domain scores found in this study are consistent with previous reports investigating the health-related quality of life in children and adolescents with NS. This study establishes known-group validity and feasibility for PROMIS pediatric measures in children and adolescents with NS. PMID:23510630

Renal replacement therapy (RRT) is growing by 10 % per year in Russia, but pre-dialysis care which can retard CKD progression and delay the start of RRT remains limited. We evaluate the effect of Essential Amino Acids and Keto-analogues (EAA/KA) on CKD progression. The effect of low protein diet (LPD), supplemented by EAA/KA, on GFR slope changes between first and second treatment period (five sequential visits per period) in 96 patients withs CKD Stage 3B-5 was compared to GFR slope changes in the control group of 96 patients, randomly selected from matched (by gender, age, diagnosis and CKD Stage) cohort of 320 patients from the city Registry. The mean baseline eGFR was 23 ± 9 ml/min/1.73 m2; 29 % had CKD3B, 45 % - CKD4, 26 % - CKD5. The rate of eGFR decline changed from -2.71 ± 2.38 to -2.01 ± 2.26 ml/min/1.73 m2 per year in the treatment group and from -2.18 ± 2.01 to -2.04 ± 2.18 ml/min/1.73 m2 per year in the control group. Only in the treatment group the difference was significant (p = 0.04 and p = 0.6). Standardized effect size for intervention was significant in treatment group: -0.3 (of pooled SD), 95 % CI -0.58 ÷  -0.02 and non-significant in control group: -0.07 (-0.35 ÷ +0.22). The univariate and multivariate analysis of EAA/KA therapy effect demonstrated that it was probably more effective in patients of older age, with higher time-averaged proteinuria (PU), lower phosphate level, in patients with glomerular v. interstitial diseases, and in females. Only the latter factor was significant at pre-specified level (<0.05). LPD combined with EAA/KA supplementation lead to the decrease of the CKD progression both in well-designed clinical study and in real nephrology practice in wide variety diseases and settings. Registry data can be helpful to reveal patients with optimal chances for beneficial effect of LPD supplemented by EAA/KA. ISRCTN28190556 06/05/2016.

Little published information is available about access failure in children undergoing chronic peritoneal dialysis. Our objectives were to evaluate frequency, risk factors, interventions, and outcome of peritoneal dialysis access revision. Data were derived from 824 incident and 1629 prevalent patients from 105 pediatric nephrology centers enrolled in the International Pediatric Peritoneal Dialysis Network Registry between 2007 and 2015. In total, 452 access revisions were recorded in 321 (13%) of 2453 patients over 3134 patient-years of follow-up, resulting in an overall access revision rate of 0.14 per treatment year. Among 824 incident patients, 186 (22.6%) underwent 188 access revisions over 1066 patient-years, yielding an access revision rate of 0.17 per treatment year; 83% of access revisions in incident patients were reported within the first year of peritoneal dialysis treatment. Catheter survival rates in incident patients were 84%, 80%, 77%, and 73% at 12, 24, 36, and 48 months, respectively. By multivariate logistic regression analysis, risk of access revision was associated with younger age (odds ratio, 0.93; 95% confidence interval, 0.92 to 0.95; P<0.001), diagnosis of congenital anomalies of the kidney and urinary tract (odds ratio, 1.28; 95% confidence interval, 1.03 to 1.59; P=0.02), coexisting ostomies (odds ratio, 1.42; 95% confidence interval, 1.07 to 1.87; P=0.01), presence of swan neck tunnel with curled intraperitoneal portion (odds ratio, 1.30; 95% confidence interval, 1.04 to 1.63; P=0.02), and high gross national income (odds ratio, 1.10; 95% confidence interval, 1.02 to 1.19; P=0.01). Main reasons for access revisions included mechanical malfunction (60%), peritonitis (16%), exit site infection (12%), and leakage (6%). Need for access revision increased the risk of peritoneal dialysis technique failure or death (hazard ratio, 1.35; 95% confidence interval, 1.10 to 1.65; P=0.003). Access dysfunction due to mechanical causes doubled the risk of technique failure compared with infectious causes (hazard ratio, 1.95; 95% confidence interval, 1.20 to 2.30; P=0.03). Peritoneal dialysis catheter revisions are common in pediatric patients on peritoneal dialysis and complicate provision of chronic peritoneal dialysis. Attention to potentially modifiable risk factors by pediatric nephrologists and pediatric surgeons should be encouraged. Copyright © 2016 by the American Society of Nephrology.

Evidence suggests that exercise training for hemodialysis patients positively improves morbidity and mortality outcomes, yet exercise programs remain rare and are not systematically incorporated into care. We developed a research-based film, Fit for Dialysis, designed to introduce, motivate, and sustain exercise for wellness amongst older hemodialysis patients, and exercise counseling and support by nephrologists, nurses, and family caregivers. The objective of this clinical trial is to determine whether and in what ways Fit for Dialysis improves outcomes and influences knowledge/attitudes regarding the importance of exercise for wellness in the context of end-stage renal disease. This 2-site parallel intervention trial will recruit 60 older hemodialysis patients from two urban hospitals. The trial will compare the film + a 16-week exercise program in one hospital, with a 16-week exercise-only program in another hospital. Physical fitness and activity measures will be performed at baseline, 8 and 16 weeks, and 12 weeks after the end of the program. These include the 2-min Walk Test, Grip Strength, Duke Activity Status Index, and the Timed Up-and-Go Test, as well as wearing a pedometer for one week. Throughout the 16-week exercise program, and at 12 weeks after, we will record patients' exercise using the Godin Leisure-time Exercise Questionnaire. Patients will also keep a diary of the exercise that they do at home on non-dialysis days. Qualitative interviews, conducted at baseline, 8, and 16 weeks, will explore the impact of Fit for Dialysis on the knowledge/attitudes of patients, family caregivers, and nephrology staff regarding exercise for wellness, and in what ways the film is effective in educating, motivating, or sustaining patient exercise during dialysis, at home, and in the community. This research will determine for whom Fit for Dialysis is effective, why, and under what conditions. If Fit for Dialysis is proven beneficial to patients, nephrology staff and family caregivers, research-based film as a model to support exercise promotion and adherence could be used to support the National Kidney Foundation's guideline recommendation (NKF-KDOQI) that exercise be incorporated into the care and treatment of dialysis patients.

Background The STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) statement was published in October 2007 to improve quality of reporting of observational studies. The aim of this review was to assess the impact of the STROBE statement on observational study reporting and study design quality in the nephrology literature. Study Design Systematic literature review. Setting & Population European and North American, Pre-dialysis Chronic Kidney Disease (CKD) cohort studies. Selection Criteria for Studies Studies assessing the association between CKD and mortality in the elderly (>65 years) published from 1st January 2002 to 31st December 2013 were included, following systematic searching of MEDLINE & EMBASE. Predictor Time period before and after the publication of the STROBE statement. Outcome Quality of study reporting using the STROBE statement and quality of study design using the Newcastle Ottawa Scale (NOS), Scottish Intercollegiate Guidelines Network (SIGN) and Critical Appraisal Skills Programme (CASP) tools. Results 37 papers (11 Pre & 26 Post STROBE) were identified from 3621 potential articles. Only four of the 22 STROBE items and their sub-criteria (objectives reporting, choice of quantitative groups and description of and carrying out sensitivity analysis) showed improvements, with the majority of items showing little change between the period before and after publication of the STROBE statement. Pre- and post-period analysis revealed a Manuscript STROBE score increase (median score 77.8% (Inter-quartile range [IQR], 64.7–82.0) vs 83% (IQR, 78.4–84.9, p = 0.05). There was no change in quality of study design with identical median scores in the two periods for NOS (Manuscript NOS score 88.9), SIGN (Manuscript SIGN score 83.3) and CASP (Manuscript CASP score 91.7) tools. Limitations Only 37 Studies from Europe and North America were included from one medical specialty. Assessment of study design largely reliant on good reporting. Conclusions This study highlights continuing deficiencies in the reporting of STROBE items and their sub-criteria in cohort studies in nephrology. There was weak evidence of improvement in the overall reporting quality, with no improvement in methodological quality of CKD cohort studies between the period before and after publication of the STROBE statement.

Renal dysfunction has a serious impact on the natural evolution of liver cirrhosis. Treatment and prognosis may be improved if an early diagnosis could be established, and specific therapeutic interventions would be applied. Although RIFLE and AKIN classifications have been successfully implemented in the clinical practice of Nephrology and Intensive Care Units, these did not provide major improvements in patients with liver cirrhosis. In the last decade, various biomarkers of kidney injury have been assessed, and Neutrophil Gelatinase-Associated Lipocalin (NGAL) is one of the most promising and most studied novel biomarker. To offer a brief evaluation on current data on the utility of this biomarker in patients with liver cirrhosis. We have searched through current literature and analyzed all significant full text articles on this topic. NGAL and other new kidney injury molecules may be useful in patients with liver cirrhosis, particularly in identifying structural kidney dysfunction, but larger validation studies to confirm this observation are needed.

The authors studied the publications written by the staff of the University Department of Urology in Budapest, Hungary between 1946 and 1956. The collection was contributed on the occasion of Professor Babics's 10-year-long chairmanship. Over a period of 10 years, 214 papers were published by 15 urologists, including 3 books and 3 PhD theses; 16 papers were published in German, 22 in English, 2 in French, and 1 in Italian. The most frequent topic of the papers (26) was basic science (e.g., ureter motility, lymph circulation, intrarenal pressure condition). Other papers dealt with nephrology, artificial kidneys, TURP, and nephron-sparing renal surgery. Some articles examined various types of malignant tumors and benign prostatic hyperplasia, while 17 publications focused on the topic of andrology. Tuberculosis was also discussed by the authors. Despite political isolation, the communist dictatorship, poverty, the lack of health equipment, physicians educated before WWII with their work morality and hard work managed to perform contemporary clinical and basic scientific research.

Technological advances in renal replacement therapy: five years and beyond.

The worldwide epidemic of chronic kidney disease shows no signs of abating in the near future. Current dialysis forms of renal replacement therapy (RRT), even though successful in sustaining life and improving quality of life somewhat for patients with ESRD, have many limitations that result in still unacceptably high morbidity and mortality. Transplantation is an excellent option but is limited by the scarcity of organs. An ideal form of RRT would mimic the functions of natural kidneys and be transparent to the patient, as well as affordable to society. Recent advances in technology, although generally in early stages of development, might achieve these goals. The application of nanotechnology, microfluidics, bioreactors with kidney cells, and miniaturized sorbent systems to regenerate dialysate makes clinical reality seem closer than ever before. Finally, stem cells hold much promise, both for kidney disease and as a source of tissues and organs. In summary, nephrology is at an exciting crossroad with the application of innovative and novel technologies to RRT that hold considerable promise for the near future.

Patient: Female, 38 Final Diagnosis: Primary hyperaldosteronism Symptoms: Paralysis Medication: — Clinical Procedure: — Specialty: Nephrology Objective: Challenging differential diagnosis Background: Thyrotoxic periodic paralysis (TPP) is commonly observed in patients with acute paralysis and hyperthyroidism. However, there is a possibility of secondary causes of hypokalemia in such a setting. Case Report: Herein, we present the case of a 38-year-old woman with untreated hypertension and hyperthyroidism. She presented with muscle weakness, nausea, vomiting, and diarrhea since one week. The initial diagnosis was TPP. However, biochemistry tests showed hypokalemia with metabolic alkalosis and renal potassium wasting. Moreover, a suppressed plasma renin level and a high plasma aldosterone level were noted, which was suggestive of primary aldosteronism. Abdominal computed tomography confirmed this diagnosis. Conclusions: Therefore, it is imperative to consider other causes of hypokalemia (apart from TPP) in a patient with hyper-thyroidism but with renal potassium wasting and metabolic alkalosis. This can help avoid delay in diagnosis of the underlying disease. PMID:28050008

Abstract The introduction of digital pathology to nephrology provides a platform for the development of new methodologies and protocols for visual, morphometric and computer-aided assessment of renal biopsies. Application of digital imaging to pathology made substantial progress over the past decade; it is now in use for education, clinical trials and translational research. Digital pathology evolved as a valuable tool to generate comprehensive structural information in digital form, a key prerequisite for achieving precision pathology for computational biology. The application of this new technology on an international scale is driving novel methods for collaborations, providing unique opportunities but also challenges. Standardization of methods needs to be rigorously evaluated and applied at each step, from specimen processing to scanning, uploading into digital repositories, morphologic, morphometric and computer-aided assessment, data collection and analysis. In this review, we discuss the status and opportunities created by the application of digital imaging to precision nephropathology, and present a vision for the near future. PMID:28584625

Integrating kidney transplantation into value-based care for people with renal failure.

Healthcare reimbursement is increasingly tied to value instead of volume, with special attention paid to resource-intensive populations such as patients with renal disease. To this end, Medicare has sponsored pilot projects to encourage providers to develop care coordination and population health management strategies to provide quality care while reducing resource utilization. In this Personal Viewpoint essay, we argue in favor of expanding one such pilot project-the Comprehensive ESRD Care (CEC) initiative-to include patients with advanced chronic kidney disease and kidney transplant recipients. The implementation of the Medicare Access and CHIP Reauthorization Act (MACRA) offers a time-sensitive incentive for transplant centers in particular to align with extant CECs. An "expanded" CEC model proffers opportunity for robust cooperation between general nephrology practices, dialysis providers, and transplant centers to develop care coordination strategies for all patients with renal disease, realign incentives for all clinical stakeholders to increase kidney transplantation rates, and reduce total costs of care. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

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. On behalf of the American Society of Nephrology Dialysis Advisory Group, we propose the need to ascertain the validity and utility of a multidimensional measure that moves beyond small solute kinetics alone to quantify optimal dialysis derived from both patient-reported and comprehensive clinical and dialysis-related measures.

1986-01-01

An international seminar on the treatment and laboratory diagnosis of yellow fever, sponsored by the Pan American Health Organization (PAHO) and held in 1984, differed from previous meetings on yellow fever because of its emphasis on the care and management of patients and because the participants included specialists from several branches of medicine, such as hepatology, haematology, cardiology, infectious diseases, pathology and nephrology. The meeting reviewed the current status of yellow fever and problems associated with case-finding and notification; features of yellow fever in individual countries of Latin America; health services and facilities for medical care as they relate to diagnosis and management of cases; prevention strategies for and current status of immunization programmes; clinical and pathological aspects of yellow fever in humans; pathogenesis and pathophysiology of yellow fever in experimental animal models; clinical and specific laboratory diagnosis; treatment of the disease and of complications in the functioning of individual organ systems; prognosis and prognostic indicators; and directions for future clinical and experimental research on pathophysiology and treatment.

Shortage of Peritoneal Dialysis Solution and the Food and Drug Administration's Response.

PubMed

2015-08-07

Although the number of new drug shortages has been lower in recent years than in the past, severe shortages have occurred that have affected large numbers of patients. A new law entitled the Food and Drug Administration Safety and Innovation Act was enacted in July of 2012, which requires companies to notify the Food and Drug Administration of anticipated shortages. This notification requirement has allowed the Food and Drug Administration to work closely with manufacturers earlier to mitigate and, often, prevent shortages. However, not all shortages are able to be prevented, and the shortage of peritoneal dialysis solution is one that has had a significant effect on patients. The Food and Drug Administration continues to use all available tools to address this shortage with manufacturers, including temporary availability of imported peritoneal dialysis solution from Ireland. Mitigating shortages is a top priority for the Food and Drug Administration, and communication with all stakeholders is essential. Copyright © 2015 by the American Society of Nephrology.

BOLD magnetic resonance imaging in nephrology

2018-01-01

Magnetic resonance (MR) imaging, a non-invasive modality that provides anatomic and physiologic information, is increasingly used for diagnosis of pathophysiologic conditions and for understanding renal physiology in humans. Although functional MR imaging methods were pioneered to investigate the brain, they also offer powerful techniques for investigation of other organ systems such as the kidneys. However, imaging the kidneys provides unique challenges due to potential complications from contrast agents. Therefore, development of non-contrast techniques to study kidney anatomy and physiology is important. Blood oxygen level-dependent (BOLD) MR is a non-contrast imaging technique that provides functional information related to renal tissue oxygenation in various pathophysiologic conditions. Here we discuss technical considerations, clinical uses and future directions for use of BOLD MR as well as complementary MR techniques to better understand renal pathophysiology. Our intent is to summarize kidney BOLD MR applications for the clinician rather than focusing on the complex physical challenges that functional MR imaging encompasses; however, we briefly discuss some of those issues.

Representatives from five international organizations (International Society of Nephrology, World Heart Federation, International Diabetes Federation, International Atherosclerosis Federation, and International Society of Hypertension) participated in a strategic planning workshop in December 2005 in Bellagio, Italy sponsored by the Rockefeller Foundation. There were equal representatives from developed and developing countries. Global perspectives on diabetes and cardiovascular and renal diseases were presented, with special emphasis on China, India, Latin America, and Africa. The rationale and effectiveness of preventive measures were discussed. It was apparent that measures for primary prevention and early intervention for all the chronic vascular diseases are similar. The five organizations agreed that an integrated global approach to chronic vascular diseases is needed. They resolved to collaborate and work towards an integrated approach to chronic vascular diseases with the establishment of a 5-year plan for the prevention and treatment of chronic vascular diseases, including public advocacy, advising international and national agencies, and improving education and the practice of established approaches.

Mothers requiring dialysis to treat end-stage kidney disease face the challenging demands of the disease and dialysis treatment in addition to their role as a parent. To describe the experience of mothers who require haemodialysis. Four mothers receiving haemodialysis treatment for end-stage kidney disease in regional Australia were interviewed to explore the mothers' experiences, attitudes, beliefs and values of their dual role as mothers and haemodialysis recipients. The overarching theme emerging from the data was the competing roles of motherhood and dialysis. Four key sub-themes emerged: fitting everything in, internal family challenges, lost connections and striving for normality. Being a mother adds a range of complexities to being on dialysis. While managing dialysis, mothers struggle to care for their children and stay connected with family life. Nephrology health professionals are uniquely placed to support mothers and need to develop strategies to ease their burdens of care. © 2014 European Dialysis and Transplant Nurses Association/European Renal Care Association.
