Authors: Dobronravov V. A. , Smirnov A. V. 
Published: July 2018

THE AIM. Analysis of etiology, clinical and morphological manifestations, of membranoproliferative glomerulonephritis (MPGN).PATIENTS AND METHODS. Retrospective analysis focused on etiology, clinical presentation, light and electron microscopy, immunoglobulins (Ig) and C3 complement component (C3) deposits was done in the cohort of MPGN cases identified in the period 2000-2017. RESULTS. Two hundred and fourteen cases of MPGN were included in the study (mean age of 44 ± 16 years). Most patients had nephrotic syndrome and significant hematuria. In 58.4% of cases, eGFR was <60 mL/min/1.73 m2, and every fifth patient had CKD stages 4 or 5. The prevalence of MPGN among all biopsy-confirmed glomerulopathies was 9.3%. Idiopathic MPGN (iMPGN) was diagnosed in 30.4% of cases, while the proportion of iMPGN cases significantly reduced along the study period. Secondary MPGN (sMPGN) was identified in 69.6% of cases (autoimmune diseases – 34.1%, infectious diseases – 16.4%, monoclonal gammopathies – 9.3%, complement-mediated damage – 9.8%). Ig+C3+MPGN was mainly associated with autoimmune diseases and infections, however 26,6% of such cases remained “idiopathic”. C3-glomerulopathy or thrombotic microangiopathy were most often causes of Ig-C3+MPGN. Ig-C3-/Ig+C3-MPGN had heterogeneous etiology. CONCLUSION. MPGN is a severe variant of glomerular damage with a heterogeneous etiological structure. Targeted routine clinical and morphological diagnostics of MPGN allows identifying the cause of the disease in most cases. This approach is reliable for the adequate treatment choice and improvement of outcomes in sMPGN. Further improvement in diagnostic and classification approaches in idiopathic MPGN relies on progress in understanding of molecular etiopathogenesis of the disease.

Published: July 2018

THE AIM: to determine the relationship between non-traditional risk factors and calcification of the aortic valve in patients with CKD C5D.PATIENTS AND METHODS. We examined 103 patients receiving treatment with program hemodialysis (53 men and 50 women, mean age 54.8 ± 15.2 years). A traditional nephrological examination was carried out, including the determination of synchronous 24-hour ECG and AD monitoring, an echocardiographic study evaluating the thickness of the carotid arteries intima-media complex. In 79 patients, the status of vitamin D was determined by the enzyme immunoassay.RESULTS.Traditional (age over 50, male and dyslipidemic) and non- traditional (duration of hemodialysis more than 5 years, calcitriol level less than 10 pmol/L) risk factors for the calcification of the aortic valve were revealed. The average concentration of calcifediol in serum was 33.3 ± 13.8 nmol /L, calcitriol – 11.5 ± 6.9 pmol /L. Calcification of the aortic valve was detected in 48 patients, 2 times more often in men. Stenosis of the aortic valve was found in 28% of men and 22% of women. During the first five years of HD, the prevalence of aortic valve calcification increased 1,5 times and continued to increase later, however, not to the degree of stenosis. The risk of stenosis increased by age over 50 years (3,6 times), whereas the use of alfacalcidol was accompanied by a 70% decrease of stenosis risk. Deficiency of calcitriol (but not calcifediol) increased the risk of calcification (but not stenosis) of the aortic valve in 2 times.CONCLUSION.Vitamin D deficiency is associated with an increased risk of developing extraosteal calcification, including aortic valve. A decrease in the concentration of calcitriol in the blood serum is a predictor for a specific lesion of the aortic valve. Adequate correction of phosphoric calcium exchange can serve as one of the methods for its prevention.

Published: July 2018

AIM: To evaluate risk factors and prevalence of acute kidney injury (AKI) in patients with chronic kidney disease (CKD) in the early period after isolated coronary artery bypass graft (CABG).PATIENTS AND METHODS:The study included 830 patients with isolated CABG. All surgeries were performed in 2016. To evaluate kidney function in preoperative period glomerular filtration rate (GFR) was estimated by Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula. AKI was diagnosed according to KDIGO criteria. Patients were stratified into two groups according to estimated glomerular filtration rate (eGFR).RESULTS:The prevalence of AKI in patients group without CKD after CABG was 11,5% (n=59), in CKD-AKI group – 12,3% (n=39). In patients with CKD and after intraoperative inotropic/vasopressor therapy use of only 2 medicinal drugs of this group the probability of AKI development increases 11,16 times (OR 11,46; 95% CI 3,47- 37,83; р<0,01). During complete bypass (CB) when haematocrit decreases on 1% AKI probability increases on 12,36% (OR 0,89; 95% CI 0,81-0,98; р=0,02). The necessity of haemodialisys, duration of stay in intensive care unit and hospitalization duration were equal to all groups. AKI-CKD development significantly increases intrahospital mortality (p<0,05). CONCLUSIONS: History of CKD increases probability of severe AKI and also mortality in early postoperative period. Revealed risk factors for AKI development are potentially modifiable.

Published: July 2018

Background Following anterior cruciate ligament reconstruction (ACLR), individuals have quadriceps muscle impairments that influence gait mechanics and may contribute to an elevated risk of knee osteoarthritis. Objectives To compare running mechanics and quadriceps function between individuals who have undergone ACLR and those in a control group, and to evaluate the association between quadriceps function and running mechanics. Methods In this controlled, cross-sectional laboratory study, 38 individuals who previously underwent primary unilateral ACLR (mean ± SD time since reconstruction, 48.0 ± 25.0 months) were matched to 38 control participants based on age, sex, and body mass index, and underwent assessments of quadriceps muscle performance and running biomechanics. Quadriceps muscle performance was assessed via isokinetic and isometric knee extension peak torque and rate of torque development (RTD) over 2 time frames: 0 to 100 milliseconds (RTD100) and 0 to 200 milliseconds (RTD200). Running evaluation included assessment of the knee flexion angle (KFA), knee extension moment (KEM), rate of knee extension moment (RKEM), vertical instantaneous loading rate, and vertical impact peak. Results On average, there was a smaller KFA (P = .016) in the involved limb compared to the uninvolved limb in the ACLR group. Compared to limbs in the control group, involved limbs in the ACLR group had lower RTD100 (P = .015), lower peak torque at 60°/s (P = .007), lower peak torque at 180°/s (P = .016), smaller KFA (P<.001), lower KEM (P = .001), lower RKEM (P = .004), and higher vertical instantaneous loading rate (P = .016). Compared to limbs in the control group, uninvolved limbs in the ACLR group had lower RTD100 (P = .003), lower peak torque at 60°/s (P = .017), and smaller KFA (P = .01). For the involved limbs in the ACLR group, there was a low correlation between isokinetic peak torque at 180°/s and RKEM (r = 0.38, P = .01), and a negligible correlation between RTD100 and RKEM (r = 0.26, P<.05). No differences were found in isometric strength for any comparison. Conclusion Individuals who have undergone ACLR have bilateral alterations in running mechanics that are weakly associated with diminished quadriceps muscle performance.

Published: July 2018

Background The influence of prior patterns of health care utilization on future health care utilization has had minimal investigation in populations with musculoskeletal disorders. Objectives The purpose of this study was to explore the relationship between presurgical health care utilization and postsurgical health care utilization in a population of patients undergoing hip surgery in the US Military Health System. Methods In this observational cohort study, person-level data were collected for patients undergoing hip arthroscopy in the Military Health System from 2003 to 2015, capturing all encounters 12 months before and 24 months after surgery for every individual. Cluster analysis was used to categorize individuals with high and low health care utilization, based on preoperative health care visits. Unadjusted and adjusted Poisson and generalized linear models were generated. Health care utilization outcomes were targeted, including costs, visits, and medication use. Results There were 1850 individuals in the final cohort (mean age, 32.18 years; 55.4% male). The high health care utilization group averaged 57.69 ± 25.87 visits, compared to 20.43 ± 8.36 visits in the low utilization group. There were significant differences between groups for total health care visits (58.17; 95% confidence interval [CI]: 57.39, 58.58), total health care costs ($11 539.71; 95% CI: $10 557.26, $12 595.04), hip-related visits (12.77; 95% CI: 12.59, 12.96), hip-related costs ($3325.07; 95% CI: $2886.43, $3804.51), days' supply of pain medications (752.67; 95% CI: 751.24, 754.11), opioid prescriptions (48.83; 95% CI: 48.47, 49.21), and cost of pain medications ($1074.80; 95% CI: $1011.91, $1137.68). Conclusion Presurgical patterns of health care utilization were associated with postsurgical patterns of health care utilization, indicating that those patients who used more care before surgery also used more care after surgery. Clinicians should consider prior patterns of health care utilization, including utilization unrelated to the index condition, when determining care plans and prognosis.

ABSTRACT Implementation of learning at the university level is expected to be conducted interactively and motivate students to participate actively in learning activities. But the reality in learning, still found learning problems about the low learning activities and student learning outcomes. While as an educator, lecturers should be able to know the problems in the learning process or lectures as an effort to improve the quality of learning. Solution to overcome the problem is by giving learning with Contextual Teaching and Learning approach (CTL) through observation method applied in Basic Ecology subject.The purpose of this research is to improve student achievement in Basic Ecology subject through learning with CTL approach and observation method. Expectations from the results of this study is as an information or input that the strategy and learning model with the method of observation can overcome the lack of activity and low student learning outcomes caused by the dominance of female students and the diversity of high school students so that the classroom climate is often noisy and reduced concentration at the time of learning. This research is experimental research, with one class of experiment of Biology student of FKIP Univet Bantara Sukoharjo second semester of class of 2016/2017 taking Basic Ecology subject. The data were collected using observation and test sheets. Technique of data analysis using T test analysis. From the analysis with T test Paired sample for two groups of dependent or pairs on pretest and postes data obtained Asymp results. Sig (2 -tailled) below 0.05 is 0.00 then Ho is rejected. This means that there are significant differences in learning outcomes before (pretest) and after CTL learning with the method of Observation (postes) in Basic Ecology subject especially on the subject matter of Population and Bird Diversity. Thus, it can be concluded that learning CTL with Observation method can improve student achievement in Basic Ecology subject especially material Population or bird diversity.

"Materia combustible": hacia una poética del amor
Authors: Rodriguez-Guridi Elena 
Published: July 2018

Este ensayo está dedicado al poemario Materia combustible de Josefa Parra, el cual explora el proceso amoroso a través de la dialéctica entre vida y muerte. La hermenéutica que Parra lleva a cabo inscribe el encuentro trascendental con el otro en la temporalidad trágica del ser mortal. Este estudio se propone demostrar cómo, en esta exégesis, Parra revela un optimismo vital que concibe la memoria y la palabra como los medios para exorcizar la transitoriedad y el desengaño del amor. El acto recursivo de la lectura, asociado para la poeta con un renacimiento, resucita la posibilidad de lo trascendental que se pierde en la existencia mortal.

This essay is devoted to the poet Josefa Parra’s collection Combustible Matter, which explores the process of love through the dialectic between life and death. Parra’s hermeneutics inscribes the transcendent encounter with the other within the tragic temporality of mortal being. This study aims to demonstrate how, in Parra’s exegesis, she reveals a vital optimism that conceives memory and the word as the means of exorcising the transient nature and disappointment of love. The recursive act of reading, for the poet linked with rebirth, reawakens the possibility of the transcendent that is lost in mortal existence.
