Visuo-tactile stimulation, but not type of movement, modulates pain during the vision of a moving virtual limb

Aims: Evidence has revealed a relationship between pain and the observation of limb movement, but it is unknown whether different types of movements have diverse modulating effects. In this immersive virtual reality study we explored the effect of the vision of different virtual arm movements (arm vs. wrist) on pain threshold from heat applied to the wrist. Patients & Methods: Forty healthy participants underwent four conditions in virtual reality while heat pain thresholds were measured. Visuo-tactile stimulation was used to attempt to modulate the feeling of virtual limb ownership. Results: Effects on pain threshold were present for type of stimulation but not type of movement. Conclusions: The type of observed movement does not appear to influence pain modulation, at least not during acute pain states

Supplemented ERA-EDTA Registry data evaluated the frequency of dialysis, kidney transplantation, and comprehensive conservative management for patients with kidney failure in Europe

The aims of this study were to determine the frequency of dialysis and kidney transplantation and to estimate the regularity of comprehensive conservative management (CCM) for patients with kidney failure in Europe. This study uses data from the ERA-EDTA Registry. Additionally, our study included supplemental data from Armenia, Germany, Hungary, Ireland, Kosovo, Luxembourg, Malta, Moldova, Montenegro, Slovenia and additional data from Israel, Italy, Slovakia using other information sources. Through an online survey, responding nephrologists estimated the frequency of CCM (i.e. planned holistic care instead of kidney replacement therapy) in 33 countries. In 2016, the overall incidence of replacement therapy for kidney failure was 132 per million population (pmp), varying from 29 (Ukraine) to 251 pmp (Greece). On 31 December 2016, the overall prevalence of kidney replacement therapy was 985 pmp, ranging from 188 (Ukraine) to 1906 pmp (Portugal). The prevalence of peritoneal dialysis (114 pmp) and home hemodialysis (28 pmp) was highest in Cyprus and Denmark respectively. The kidney transplantation rate was nearly zero in some countries and highest in Spain (64 pmp). In 28 countries with five or more responding nephrologists, the median percentage of candidates for kidney replacement therapy who were offered CCM in 2018 varied between none (Slovakia and Slovenia) and 20% (Finland) whereas the median prevalence of CCM varied between none (Slovenia) and 15% (Hungary). Thus, the substantial differences across Europe in the frequency of kidney replacement therapy and CCM indicate the need for improvement in access to various treatment options for patients with kidney failure.Peer reviewe

The European Renal Association - European Dialysis and Transplant Association (ERA-EDTA) Registry Annual Report 2016 : a summary

Background. This article summarizes the ERA-EDTA Registry's 2016 Annual Report, by describing the epidemiology of renal replacement therapy (RRT) for end-stage renal disease (ESRD) in 2016 within 36 countries. Methods. In 2017 and 2018, the ERA-EDTA Registry received data on patients undergoing RRT for ESRD in 2016 from 52 national or regional renal registries. In all, 32 registries provided individual patient data and 20 provided aggregated data. The incidence and prevalence of RRT and the survival probabilities of these patients were determined. Results. In 2016, the incidence of RRT for ESRD was 121 per million population (pmp), ranging from 29 pmp in Ukraine to 251 pmp in Greece. Almost two-thirds of patients were men, over half were aged >= 65 years and almost a quarter had diabetes mellitus as their primary renal diagnosis. Treatment modality at the start of RRT was haemodialysis for 84% of patients. On 31 December 2016, the prevalence of RRT was 823 pmp, ranging from 188 pmp in Ukraine to 1906 pmp in Portugal. In 2016, the transplant rate was 32 pmp, varying from 3 pmp in Ukraine to 94 pmp in the Spanish region of Catalonia. For patients commencing RRT during 2007-11, the 5-year unadjusted patient survival probability on all RRT modalities combined was 50.5%. For 2016, the incidence and prevalence of RRT were higher among men (187 and 1381 pmp) than women (101 and 827 pmp), and men had a higher rate of kidney transplantation (59 pmp) compared with women (33 pmp). For patients starting dialysis and for patients receiving a kidney transplant during 2007-11, the adjusted patient survival probabilities appeared to be higher for women than for men.Peer reviewe

The epidemiology of renal replacement therapy in two different parts of the worldThe Latin American Dialysis and Transplant Registry versus the European Renal Association-European Dialysis and Transplant Association Registry

Publisher Copyright: © 2018 Pan American Health Organization. All rights reserved.Objective: To compare the epidemiology of renal replacement therapy (RRT) for end-stage renal disease (ESRD) in Latin America and Europe, as well as to study differences in macro-economic indicators, demographic and clinical patient characteristics, mortality rates, and causes of death between these two populations. Methods: We used data from 20 Latin American and 49 European national and subnational renal registries that had provided data to the Latin American Dialysis and Renal Transplant Registry (RLADTR) and the European Renal Association-European Dialysis and Transplant Association (ERA-EDTA) Registry, respectively. The incidence and prevalence of RRT in 2013 were calculated per million population (pmp), overall and by subcategories of age, sex, primary renal disease, and treatment modality. The correlation between gross domestic product and the prevalence of RRT was analyzed using linear regression. Trends in the prevalence of RRT between 2004 and 2013 were assessed using Joinpoint regression analysis. Results: In 2013, the overall incidence at day 91 after the onset of RRT was 181 pmp for Latin American countries and 130 pmp for European countries. The overall prevalence was 660 pmp for Latin America and 782 pmp for Europe. In the Latin American countries, the annual increase in the prevalence averaged 4.0% (95% confdence interval (CI): 2.5%-5.6%) from 2004 to 2013, while the European countries showed an average annual increase of 2.2% (95% CI: 2.0%-2.4%) for the same time period. The crude mortality rate was higher in Latin America than in Europe (112 versus 100 deaths per 1 000 patient-years), and cardiovascular disease was the main cause of death in both of those regions. Conclusions. There are considerable differences between Latin America and Europe in the epidemiology of RRT for ESRD. Further research is needed to explore the reasons for these differences.Peer reviewe

Telomere length shortening and gastric cancer risk in a high risk Polish population

Abnormally short telomeres have been associated with chronic inflammation and chromosomal instability. Increased rates of telomere shortening are present in gastric tumor tissue and in gastric epithelium tissue infected with Helicobacter pylori (H. pylori), a known risk factor for gastric cancer. However, no study has examined the role of telomere length in peripheral blood genomic DNA in relation to H. pylori infection and gastric cancer risk. In a population-based study of 300 cases and 416 controls conducted in Warsaw, Poland, between 1994 and 1996, we examined: i) the association between telomere length in peripheral blood genomic DNA and potential gastric cancer risk factors, including H. pylori infection among healthy controls; ii) the risk of gastric cancer associated with shortened telomeres. Telomere length (TL) was measured in duplicate using real-time quantitative PCR. The mean of the two measurements was used to calculate the relative ratio of telomere repeat to single-copy gene number (T/S ratio). We used regression models to obtain age-adjusted p-values for the correlations of telomere length with H. pylori infection and other exposures. Age-adjusted logistic regression models were used to estimate gastric cancer risk associated with telomere length. Among controls, telomere length was significantly shorter in H. pylori-infected individuals (TL=1.32, SD=0.34) than in uninfected subjects (TL=1.44, SD=0.35; p =0.03). We also observed significant inverse correlations of telomere length with age (p<0.001), pack years of cigarette smoking (p=0.003), total years of alcohol consumption (p=0.007), and low weekly fruit intake (p=0.02). When cases and controls were compared, telomere length was significantly shorter in cases (TL=1.25; SD=0.34) than in controls (TL=1.34; SD=0.35) [p=0.0008]. Furthermore, gastric cancer risk was significantly increased with decreasing telomere length (OR=2.00, 95% CI=1.32-3.02 for subjects in the lowest quartile (shortest) of telomere length compared to those in the highest quartile of telomere length; P trend<0.001). Our results suggest that H. pylori infection and other potential gastric cancer risk factors are associated with shorter telomeres. Shortened telomere length was associated with an increased risk of gastric cancer in this high-risk Polish population
