Reassessment of renal prognosis in patients with membranoproliferative glomerulonephritis according to the new pathologic classification
Authors: Parmaksız Ergün , Meşe Meral 
Published: December 2020

Membranoproliferative glomerulonephritis (MPGN) is a heterogeneous disease characterized by a morphological injury pattern that can be seen under various disease conditions that share common pathogenic mechanisms. In this study, we analyzed clinical features, pathological findings, long-term kidney outcomes according to the new pathohistological classification of MPGN.
Methods. This retrospective study included 20 CKD patients with biopsy-proven MPGN that had been diagnosed between 2011 and 2019. We reclassified the patterns of MPGN as immune-complexes mediated (ICM) and complement-mediated (CM) according to the new classification.
Results. The level of daily proteinuria was lower in the ICM MPGN than the CM MPGN group but was not statistically significant at the end of the study. Histopathologically, the difference in C3 staining was found between the patients with ICM and CM MPGN. At the end of the follow-up period, no patients developed end-stage renal disease, and no death occurred in response to treatment in the ICM MPGN group. In the CM MPGN group, 2 patients evolved to end-stage renal disease and 1 of them had renal transplantation.
Conclusion. Larger sample size and longer follow-up may change the relationship between histological factors, treatment strategies, and kidney outcomes. We believe that the use of the new diagnostic approach that applies to the ICM MPGN and CM MPGN will help nephrologists to improve treatment options and renal outcomes for patients with MPGN.

Anemia is a common complication of chronic kidney disease (CKD). The most common cause of anemia in CKD is erythropoietin deficiency; and the most important cause of mortality in CKD patients is atherosclerotic vascular complications which are associated with endothelial damage. One of the methods evaluating vascular integrity is the cytometric measurement of circulating endothelial cells and endothelial progenitor cells in peripheral blood. The study aimed to investigate the effects of erythropoietin therapy on endothelial dysfunction by evaluating circulating endothelial cells and endothelial progenitor cells in peripheral blood using the technique of flow cytometry.
Methods. A total of 55 hemodialysis patients were evaluated in three groups; those having erythropoietin therapy for at least last 3 months (n = 20) / not having erythropoietin for at least the last 3 months (n = 20) and the patients who started erythropoietin treatment during the study (n = 5). The control group consisted of 20 people. Blood values of the 3rd Group were investigated three times as baseline, 2nd week and 8th week CD34 +, CD105 + cells were evaluated as activated circulating endothelial cells; CD133 +, CD146 + cells were evaluated as activated endothelial progenitor cells.
Results. There was no difference between the patients and healthy individuals in terms of circulating endothelial cells and endothelial progenitor cells. In the third group, no differences were observed in circulating endothelial cells / endothelial progenitor cell levels at baseline / 2nd and 8th weeks. There was no correlation between erythropoietin and circulating endothelial cells / endothelial progenitor cells.
Conclusion. A correlation is not available between the therapeutic doses of erythropoietin used in hemodialysis patients and circulating endothelial cells / endothelial progenitor cell levels; supratherapeutic doses could change the results.

Published: December 2020

the study aimed to investigate the relationship between red blood cell membrane disorders and Doppler ultrasound indices of renal blood flow in patients with chronic kidney disease (CKD) stages1-2.
Methods. The complex clinical, laboratory and instrumental (color duplex Doppler scanning of renal parenchyma vessels) examination was conducted in 131 CKD stage 1-2 patients. Among them, there were 47 patients with pyelonephritis, 48 patients with diabetic nephropathy, and 36 patients with primary glomerulonephritis. Each patients’ group was divided into 2 subgroups: with and without arterial hypertension. Twenty healthy volunteers were also included for the study control.
Results. A significant correlation between indices of the erythrocytes morphology and basic Doppler ultrasonography parameters of the kidney vessels circulation, namely a.interlobaris was demonstrated in CKD patients with arterial hypertension. The most significant changes were observed in diabetic patients.
Conclusion. The results of our study indicated a high informative value of renal Doppler ultrasonography as a non-invasive technique to diagnose the CKD progression in patients with comorbid hypertension
A comparative study of the identification frequency and composition of bacteria isolated from catheter and urine in urologic patients: A single-center descriptive study

Published: December 2020

This study aimed to compare the identification frequency and composition of bacteria isolated from catheter and urine in urologic patients.
Methods: Ninety patients with urethral catheters were involved in the study. Urinary and catheter cultures were taken simultaneously from each patient and cultured on MacConkey's agar. Urine culture and sensitivity were performed for all samples in pre- and postoperative periods. Swab culture and sensitivity from the surface of intraluminal urethral catheters were performed for all cases in the post-operative period.
Results: The median indwelling period of the catheters was 8 days (range 3 to 21). The overall positive rate of catheter culture was significantly greater than that of urine culture, even in subjects without a recent antibacterial agent history. Urine cultures and catheter cultures did not match each other completely. The percentage of patients who had the same bacterial species isolated from both specimens increased in a time-dependent manner.
Conclusions: Not all species of bacteria colonizing the intraluminal surface of the urethral catheter were detected as urinary bacteria. Bacterial colonization on the intraluminal catheter surface could precede the emergence of bacteriuria.
Do we need new scales for assessing the risk of thromboembolic events and bleeding for patients with chronic kidney disease?
Authors: Mykhaloiko I. , Dudar I. 
Published: December 2020

Chronic kidney disease (CKD) is a global health problem. Patients with CKD have an increased risk of thromboembolic complications and bleeding.
It remains difficult to determine the benefits and risks of antiplatelet and anticoagulant therapy in patients with CKD, so an individualized risk assessment of each patient should be mandatory.
To date, there are no specialized scales for assessing the risk of thromboembolic events and bleeding, which are focused on patients with CKD and take into account all the features of the course of CKD and the specific factors of their occurrence.
In this work, we decided to conduct a detailed assessment of the accuracy of the currently accepted risk scales for thromboembolic events and bleeding in patients with CKD.

Sentidos morales, éticos y políticos de las prácticas ciudadanas de jóvenes universitarios colombianos
Authors: Echavarrí Grajales Carlos Valerio , Rodríguez García Hernán Ferney 
Published: December 2020

Este artículo describe los sentidos morales, éticos y políticos que para un grupo de jóvenes universitarios del programa de Licenciatura en lengua castellana, inglés y francés de la Facultad de Ciencias de la Educación de la Universidad de La Salle de Bogotá, Colombia, tienen sus prácticas ciudadanas. Se realizó una investigación cualitativa, siguiendo el enfoque etnográfico, con información sistematizada y analizadaÂ resultante de la elaboración de cinco talleres pedagógicos para interpretar y comprender dichos sentidos. Como fundamentación teórica se retomaron planteamientos de Taylor (1994, 1996, 1997, 2004, 2006), Fraser y Honneth (2006) y Honneth (1997, 2007, 2009), sobre reconocimiento y reificación. Algunos resultados e inferencias dan cuenta del vaciamiento de sentido, el tedio y hasta el hastío que sienten los jóvenes cuando no se presentan, desde el marco administrativo e institucional, condiciones justas, de equidad y de justicia redistributiva. Se concluye que para los jóvenes es necesario que el Estado y sus instituciones reconozcan tanto las condiciones de afectación de la dignidad, como los efectos que puede llegar a tener una política pública en las subjetividades ciudadanas. Igualmente, el Estado debe preguntarse por las motivaciones morales e intencionalidades políticas que tendrían los jóvenes para vincularse solidariamente al acuerdo normativo constitucional.
Venezuela: Política económica, ajuste y crecimiento. Las dos agendas con el F.M.I.
Authors: Risquez Justino 
Published: December 2020

En los últimos nueve años se han aplicado dos planes de ajustes en la economía venezolana, bajo la forma de acuerdos stand-by con el F. M. I. Ambos programas son muy similares por su naturaleza y porÂ lo tanto por sus efectos, aún cuando las condiciones de la economía en el momento no eran exactamente las mismas. En este trabajo se hace un estudio comparativo de estos programas; encontrándose como similitud el elevado efecto recesivo que en el corto plazo produjeron, así como la persistencia de una relativamente alta tasa de inflación en el mediano plazo. Como diferencia se observa el importante desequilibrio monetario que se ha mantenido en la última experiencia, debido a que las autoridades han perdido el control sobe la oferta monetaria. Así mismo se concluye, que en ambos casos el principal objetivo perseguido como es el de eliminarla inestabilidad de precios no se ha conseguido.

Keamanan dan kerahasiaan menjadi aspek yang sangat penting bagi pengguna teknologi informasi. Untuk menghindari pesan yang dikirimkan jatuh pada pihak-pihak yang tidak berkepentingan dan terjadi penyalahgunaan terhadap pesan. Banyak cara yang dapat dilakukan untuk menyembunyikan data atau pesan yang akan dikirim. Salah satunya adalah steganografi. Steganografi adalah teknik menyisipkan pesan ke media lain, sehingga pesan tersebut akan tersembunyi dan yang akan nampak adalah media lain untuk menyisipkan pesan. Steganografi memerlukan pesan dan cover. Cover adalah media yang digunakan untuk menyisipkan pesan. Penelitian ini bertujuan untuk menyisipkan pesan berupa citra ke dalam cover berupa citra dengan format JPG dan PNG. Pada penelitian ini menggunakan metode Least Significant Bit (LSB) sebagai metode penyisipan dan metode modifikasi bit untuk mengoptimalkan kinerja LSB dalam menyisipkan pesan 1 hingga 4 bit. Hasil penelitian menunjukkan bahwa proses penyisipan citra berdasarkan unjuk kerja koefisien korelasi dan PSNR menunjukkan jumlah bit terbaik dalam proses penyisipan adalah berjumlah 1 bit. Pada proses ekstraksi citra pesan berdasarkan unjuk kerja koefisien korelasi dan MAPE menunjukkan jumlah bit terbaik dari proses penyisipan adalah berjumlah 4 bit. Sedangkan format terbaik adalah jika citra cover dan citra pesan dalam format PNG. Disimpulkan, semakin banyak bit yang disisipkan maka kualitas cover akan semakin menurun tetapi hasil ekstraksi semakin tinggi tingkat keberhasilannya dalam kembalinya pesan.

Published: December 2020

Il lavoro analizza gli effetti dell'entrata in vigore dell'IFRS 7, emanato dallo IASB con lo scopo di aumentare l'informazione sull'esposizione delle imprese ai rischi di mercato. La nostra ricerca indaga l'utilità per gli investitori dell'analisi di sensitività al rischio di tasso di cambio fornita dalle società quotate italiane. I risultati mostrano che prima dell'introduzione dell'IFRS 7 il mercato stimava erroneamente l'esposizione al tasso di cambio, mentre successivamente la sensitività dei rendimenti al tasso di cambio sembra allinearsi con le esposizioni dichiarate. Dall'analisi, inoltre, emerge che l'informazione sull'esposizione riduce la sensitività dei volumi al tasso di cambio. I nostri risultati integrano la letteratura statunitense fornendo evidenze di come un'analisi di sensitività anchesia utile al mercato.

Il progetto congiunto IASB-FASBsi propone di definire l'impostazione di tutti i documenti necessari per formare un bilancio di esercizio che possa definirsi completo, ma grande attenzione è dedicata alla struttura del conto economico e alla rappresentazione del. Nel momento in cui i due corpi di principi contabili adottano un sistema misto di riconoscimento e di valutazione, fondato in parte sul costo storico e sul principio di realizzazione e in parte sule sulla logica delle variazioni patrimoniali, si pone il problema di valutare se la rappresentazione del reddito debba riflettere in modo neutro l'esistenza di questi due diversi paradigmi. Il lavoro esamina le soluzioni proposte nella struttura di conto economico al fine di esprimere su di esse un giudizio di merito alla luce delle indicazioni provenienti dai contributi teorici e dalle indagini empiriche svolte sull'argomento. Le innovazioni presentano indubbi vantaggi ma non risolvono le principali criticità legate alla rappresentazione del. L'incertezza che emerge dai contributi teorici ed empirici, che non consentono di individuare argomenti decisivi per basare le valutazioni esclusivamente sul reddito tradizionale o sul, rappresentano il principale argomento a supporto delle scelte conservative avanzate dai due.

Published: December 2020

Background: Diabetes mellitus has become a public health problem globally. Type 2 diabetes mellitus, caused by lifestyle and high lipid diet, is the most common form. Hypercholesterolemia-diabetes is able to create endothelial injury that results in formation of atherosclerosis, starting with formation of foam cells.
Objective: This research aimed to see the effectiveness of physical training and soursop (Annona muricata) leaves extract in lowering the amount of foam cells.
Methods: This research was an experimental study which used the post test-only control group design with 35 Wistar strain rats which were randomly divided into 7 groups, each consisting of 5 rats. K1 was given standard diet, K2 was given atherogenic diet and alloxan, while K3, K4, K5, K6, and K7 were given atherogenic diet, alloxan, and different treatments based on designed group. K3 was given simvastatin, K4 was given metformin, K5 was given physical training, K6 was given soursop leaves extract (SLE), and K7 was given both physical training and SLE. The rats were euthanized after three weeks and aorta was taken to be made into histology slides for foam cells observation.
Results: The result of Kruskal-Wallis and Mann-Whitney Post-Hoc Test showed significant difference (p<0,05) between K2 and K5, K6, K7 while it no significant difference (p>0,05) between K3, K4 and K5, K6, K7.
Conclusion: Physical training, SLE, and the combination of both have a role in lowering formation of foam cells in atherosclerosis.
