Effect of telemedicine for patients with chronic kidney disease who perform dialysis at home: a systematic review

Introduction and background: The world’s population is getting older, and the prevalence of chronic kidney disease (CKD) rises parallel with age. CKD is a major public health concern, characterised by poor health outcomes and a high economic burden for society as well as for the individual. With an aging population, there is an increasing need to organize healthcare services in alternative ways. There are two main types of dialysis, peritoneal dialysis (PD) and hemodialysis (HD), and both can be performed by the patient at home. Telemedicine (TM) gives the patient quick access to medical expertise independent of the distance to a treatment centre. The use of technology provides possibilities for thorough patient follow-up (FU), and at the same time, saving human resources. Objective: To systematically review the effectiveness of FU by TM compared to standard care for adult patients with dialysis-dependent CKD on home dialysis, including PD and HD. Methods: A systematic review that followed the Cochrane Handbook for Systematic Reviews of Interventions was conducted. Results: The findings suggested that TM FU was effective in reducing hospitalizations and technical failure as the cause for transfer to a different dialysis modality. The effects of TM FU on overall quality of life and infections were inconclusive. No studies included the outcome ‘time patients used for travel’. The certainty of evidence (GRADE) was rated as very low or low for all the outcomes, and the results must be interpreted with caution. Author’s conclusions: The evidence suggests that there may be positive effects and no harms regarding technical failure and hospitalizations from TM patient FU. However, there is a large research gap and further research in the form of primary studies with high methodological quality are needed to draw stronger conclusions

Big data analytics for preventive medicine

© 2019, Springer-Verlag London Ltd., part of Springer Nature. Medical data is one of the most rewarding and yet most complicated data to analyze. How can healthcare providers use modern data analytics tools and technologies to analyze and create value from complex data? Data analytics, with its promise to efficiently discover valuable pattern by analyzing large amount of unstructured, heterogeneous, non-standard and incomplete healthcare data. It does not only forecast but also helps in decision making and is increasingly noticed as breakthrough in ongoing advancement with the goal is to improve the quality of patient care and reduces the healthcare cost. The aim of this study is to provide a comprehensive and structured overview of extensive research on the advancement of data analytics methods for disease prevention. This review first introduces disease prevention and its challenges followed by traditional prevention methodologies. We summarize state-of-the-art data analytics algorithms used for classification of disease, clustering (unusually high incidence of a particular disease), anomalies detection (detection of disease) and association as well as their respective advantages, drawbacks and guidelines for selection of specific model followed by discussion on recent development and successful application of disease prevention methods. The article concludes with open research challenges and recommendations

Progress in Hemodialysis

Hemodialysis (HD) represents the first successful long-term substitutive therapy with an artificial organ for severe failure of a vital organ. Because HD was started many decades ago, a book on HD may not appear to be up-to-date. Indeed, HD covers many basic and clinical aspects and this book reflects the rapid expansion of new and controversial aspects either in the biotechnological or in the clinical field. This book revises new technologies and therapeutic options to improve dialysis treatment of uremic patients. This book consists of three parts: modeling, methods and technique, prognosis and complications

Smoking and Second Hand Smoking in Adolescents with Chronic Kidney Disease: A Report from the Chronic Kidney Disease in Children (CKiD) Cohort Study

The goal of this study was to determine the prevalence of smoking and second hand smoking [SHS] in adolescents with CKD and their relationship to baseline parameters at enrollment in the CKiD, observational cohort study of 600 children (aged 1-16 yrs) with Schwartz estimated GFR of 30-90 ml/min/1.73m2. 239 adolescents had self-report survey data on smoking and SHS exposure: 21 [9%] subjects had “ever” smoked a cigarette. Among them, 4 were current and 17 were former smokers. Hypertension was more prevalent in those that had “ever” smoked a cigarette (42%) compared to non-smokers (9%), p\u3c0.01. Among 218 non-smokers, 130 (59%) were male, 142 (65%) were Caucasian; 60 (28%) reported SHS exposure compared to 158 (72%) with no exposure. Non-smoker adolescents with SHS exposure were compared to those without SHS exposure. There was no racial, age, or gender differences between both groups. Baseline creatinine, diastolic hypertension, C reactive protein, lipid profile, GFR and hemoglobin were not statistically different. Significantly higher protein to creatinine ratio (0.90 vs. 0.53, p\u3c0.01) was observed in those exposed to SHS compared to those not exposed. Exposed adolescents were heavier than non-exposed adolescents (85th percentile vs. 55th percentile for BMI, p\u3c 0.01). Uncontrolled casual systolic hypertension was twice as prevalent among those exposed to SHS (16%) compared to those not exposed to SHS (7%), though the difference was not statistically significant (p= 0.07). Adjusted multivariate regression analysis [OR (95% CI)] showed that increased protein to creatinine ratio [1.34 (1.03, 1.75)] and higher BMI [1.14 (1.02, 1.29)] were independently associated with exposure to SHS among non-smoker adolescents. These results reveal that among adolescents with CKD, cigarette use is low and SHS is highly prevalent. The association of smoking with hypertension and SHS with increased proteinuria suggests a possible role of these factors in CKD progression and cardiovascular outcomes

Primary hepatitis C virus infection in prisons

Infection with hepatitis C virus (HCV) causes significant morbidity and mortality. An understanding of the factors associated with both acquisition and clearance of HCV infection is critical to prevention strategies including vaccine development. Although research in the prison environment is logistically challenging, inmates are a premier risk group. Accordingly, a prospective cohort study of prisoners with monthly sampling for HCV viraemia was undertaken to assess the incidence of, and risk factors for, infection; and to assess the natural history of infection when detected by viraemia. The incidence of infection was 8 per 100 person years, with the incidence of "high risk" and "possible" HCV transmission risk events being 61 and 210 per 100 person years respectively. The first case of HCV infection in prison with tattooing as the probable route of acquisition was reported. A novel phenotype of HCV infection with HCV viraemia and subsequent clearance without the development of symptoms, biochemical hepatitis or seroconversion on HCV specific enzyme immunoassay (EIA), despite more than one year of follow-up, was reported. HCV-specific cell mediated immune responses were detected in the subjects analysed. These subjects also had indeterminate HCV serological responses directed against non-structural proteins detected on a recombinant immunob10t assay (RIBA) that were stable over time and typically predated HCV viraemia. The prevalence of such responses ranged from 29-79% in other relevant cohorts, including injecting drug users (IDUs) and multiply-transfused patients with thalassaemia. The antibody response against the non-structural protein, NS5 was the most reproducible. This reactivity was blocked in 57% of subjects when sera were pre-incubated with recombinant HCV proteins, suggesting HCV-specificity. A case-control study was undertaken to examine whether such responses predicted protection from "classical" HCV infection with EIA seroconversion. Cases that developed HCV viraemia and EIA seroconversion were more likely to have these responses at baseline (when aviraemic) than controls, demonstrating that they do not protect against acute infection. However, the rate of viral clearance in subjects with indeterminate RIBA responses that subsequently developed acute infection and were followed for viral clearance was high (88%), suggesting that such subjects have immune responses that are associated with viral clearance
