[Bilateral laparoscopic nephrectomy for polycystic kidney disease].

A clinical case of surgical treatment of a patient with autosomal dominant type of polycystic kidney disease, stage 5 of chronic kidney disease and secondary arterial hypertension is presented in the article. The technique of single-stage bilateral laparoscopic nephrectomy, patented by the authors, is described. The practicability and safety of a simultaneous bilateral procedures was demonstrated, as well as the advantage of laparoscopic access for this type of surgical interventions.

[Laparoscopic partial nephrectomy using a technology of augmented reality: new vector of the development of operative urology?].

Aim: to evaluate the efficiency and usefulness of augmented reality (AR) technology using HoloLens glasses for laparoscopic partial nephrectomy (LPN).

Materials And Methods: From July to December 2019, a total of 5 patients with localized kidney cancer (cT1aN0M0) underwent AR-assisted LRP. The mean RENAL score was 6 points (5-8).

Emergence of Five Genetic Lines ST395, ST13, ST3346, ST39, and Novel ST3551 of Multidrug-Resistant Clinical in Russia.

The objective of this study was phenotypic and genotypic characterization of antibacterial-resistant clinical strains isolated in Moscow Transplantology Intensive Care Unit in 2017-2019. Major strains among ( = 63) isolated from 30 patients were recognized as extensive drug-resistant ( = 55) pathogens, and remaining strains were recognized as multidrug-resistant ( = 8) pathogens. The beta-lactamase genes ( = 63), ( = 61), ( = 54), ( = 52), and ( = 2), as well as class 1 integrons ( = 19) carried gene cassette arrays A4 ( = 2), A1C ( = 6), BA1 ( = 9), A15A1 ( = 3), and A12 ( = 1) were identified in the strains.

Haemodynamic evaluation of the new pulsatile-flow generation method in vitro.

Continuous-flow ventricular-assist devices are widely used to support patients with advanced heart failure, because continuous-flow ventricular-assist devices are more durable, have smaller sizes and have better survival rates for patients compared to the pulsatile-flow ventricular-assist devices. Nevertheless, continuous-flow ventricular-assist devices often cause complications such as gastrointestinal bleeding, haemorrhagic stroke, and aortic insufficiency and have a negative impact on the microcirculation for both long-time implantable and short-time extracorporeal systems. The aim of this study is the evaluation of the pulsatile-flow generation method in continuous-flow ventricular-assist device without pump speed changes.

Global Cardiovascular and Renal Outcomes of Reduced GFR.

The burden of premature death and health loss from ESRD is well described. Less is known regarding the burden of cardiovascular disease attributable to reduced GFR. We estimated the prevalence of reduced GFR categories 3, 4, and 5 (not on RRT) for 188 countries at six time points from 1990 to 2013.

Hemodialysis practice patterns in the Russia Dialysis Outcomes and Practice Patterns Study (DOPPS), with international comparisons.

Introduction: There is little comparable information about hemodialysis (HD) practices in low- and middle income countries, including Russia. Evaluation of HD in Russia and its international comparisons could highlight factors providing opportunities for improvement.

Methods: We examined treatment patterns for 481 prevalent HD patients in 20 Russian facilities, and compared them to contemporary data for 8512 patients from 311 facilities in seven European countries, Japan, and North America.

3D printing of PLGA scaffolds for tissue engineering.

We proposed a novel method of generation of bioresorbable polymeric scaffolds with specified architectonics for tissue engineering using extrusion three-dimensional (3D) printing with solutions of polylactoglycolide in tetraglycol with their subsequent solidifying in aqueous medium. On the basis of 3D computer models, we obtained the matrix structures with interconnected system of pores ranging in size from 0.5 to 500 µm.

Renal replacement therapy in Europe: a summary of the 2013 ERA-EDTA Registry Annual Report with a focus on diabetes mellitus.

Background: This article provides a summary of the 2013 European Renal Association-European Dialysis and Transplant Association (ERA-EDTA) Registry Annual Report (available at http://www.era-edta-reg.org), with a focus on patients with diabetes mellitus (DM) as the cause of end-stage renal disease (ESRD).

Chronic kidney disease and cardiovascular risk in six regions of the world (ISN-KDDC): a cross-sectional study.

Background: Chronic kidney disease is an important cause of global mortality and morbidity. Data for epidemiological features of chronic kidney disease and its risk factors are limited for low-income and middle-income countries. The International Society of Nephrology's Kidney Disease Data Center (ISN-KDDC) aimed to assess the prevalence and awareness of chronic kidney disease and its risk factors, and to investigate the risk of cardiovascular disease, in countries of low and middle income.

Maintenance Dialysis throughout the World in Years 1990 and 2010.

Rapidly rising global rates of chronic diseases portend a consequent rise in ESRD. Despite this, kidney disease is not included in the list of noncommunicable diseases (NCDs) targeted by the United Nations for 25% reduction by year 2025. In an effort to accurately report the trajectory and pattern of global growth of maintenance dialysis, we present the change in prevalence and incidence from 1990 to 2010.

The cell-engineered construct of cartilage on the basis of biopolymer hydrogel matrix and human adipose tissue-derived mesenchymal stromal cells (in vitro study).

The study results of in vitro formation of tissue-engineered cartilage construct on the basis of cell-engineered construct composed of biopolymer hydrogel matrix and human adipose tissue-derived mesenchymal stromal cells (hADSCs) are presented. It was revealed that hADSCs in biopolymer hydrogel matrix Sphero®GEL under chondrogenic conditions generate three-dimensional structures and produce cartilaginous extracellular matrix components: collagen type II and glycosaminoglycans.

Unsaturated lipids protect the integral membrane peptide gramicidin A from singlet oxygen.

In contrast to expectations that unsaturated fatty acids contribute to oxidative stress by providing a source of lipid peroxides, we demonstrated the protective effect of double bonds in lipids on oxidative damage to membrane proteins. Photodynamic inactivation of gramicidin channels was decreased in unsaturated lipid compared to saturated lipid bilayers. By estimating photosensitizer (boronated chlorine e6 amide) binding to the membrane with the current relaxation technique, the decrease in gramicidin photoinactivation was attributed to singlet oxygen scavenging by double bonds in lipids rather than to the reduction in photosensitizer binding.

Mortality landscape in the global burden of diseases, injuries and risk factors study.

The Global Burden of Diseases, Injuries and Risk Factors Study 2010 (GBD 2010) is an initiative that involved 486 scientists from 302 institutions in 50 countries, under the leadership of a consortium formed by the Institute for Health Metrics and Evaluation of the University of Washington, World Health Organization, the University of Queensland School of Population Health, the Harvard School of Public Health, the Johns Hopkins Bloomberg School of Public Health, the University of Tokyo and Imperial College London. The study has provided a state of the art understanding of the burden of 67 risk factors and their clusters, 291 diseases and injuries on global, regional and national levels in period from 1990 to 2010 for 187 countries. GBD 2010 estimates covered both mortality (expressed in number of deaths, years of life lost (YLL) due to premature mortality) and morbidity (mainly expressed as years lived with disability (YLD)), while the incidence and prevalence were not reported for majority of causes so far, although they were accounted and used for YLD calculations.
