En el presente trabaio se crecieron peliculas delgadas de Ti6Al4V sobre sustratos de acero 316L, con la técnica de pulverización catódica magnetrón rt, variando los parámetros de crecimiento. A los recubrimientosse les realizó un estudio morfológico y de composición a través de Microscopía Electrónica de Barrido(SEM) y análisis estructural mediante difracción de rayos X (DRX)). El comportamiento a la corrosión, se estableció por medio de la técnica de espectroscopia de impedancia electroquímica (EIS). Los resultados de SEM muestran que a medida que se incrementa la potencia incidente sobre el blanco la homogeneidad de las peliculas aumenta y la composición de la película no tiene una variación significativa. El estudio de DRX muestra que existe un crecimiento de los planos (110) y (220) de la fase β de la aleación. Los resultados de EIS han permitido determinar que la resistencia a la corrosión se incrementa, pues el valor de la resistencia a la polarización de las probetas recubiertas se incrementa 3 órdenes de magnitud con respecto al sustrato.Palabras Clave: Biomateriales; Películas Delgadas;Corrosión.

Aim. To identify clustering areas of COVID-19 cases during the first 3 months of pandemic in a million city.Materials and Methods. We collected the data on polymerase chain reaction verified cases of novel coronavirus infection (COVID-19) in Omsk for the period from April, 15 until July 1, 2020. We have drawn heat maps using Epanechnikov kernel and calculated Getis-Ord general G statistic (Gi*). Analysis of geographic information was carried out in QGIS 3.14 Pi (qgis.org) software using the Visualist plugin.Results. Having inspected spatial distribution of COVID-19 cases, we identified certain clustering areas. The spread of COVID-19 involved Sovietskiy, Central and Kirovskiy districts, and also Leninskiy and Oktyabrskiy districts a short time later. We found uneven spatiotemporal distribution of COVID-19 cases infection across Omsk, as 13 separate clusters were documented in all administrative districts of the city.Conclusions. Rapid assessment of spatial distribution of the infection employing geographic information systems enables design of kernel density maps and harbors a considerable potential for real-time planning of preventive measures.

Aim. To evaluate the role of intestinal dysbiosis in the development of urinary tract infections in children admitted to a multidisciplinary hospital.Materials and Methods. We performed a bacteriological analysis of 2,694 urine samples collected from ≤ 3-years-old children who have been admitted to a multidisciplinary hospital (Kemerovo, Russian Federation). Urine specimens were inoculated by the 4-sector technique. Concurrently, we quantified the intestinal microbiota and its antimicrobial resistance in 100 children with urinary tract infections.Results. Titers of pathogenic microbes significantly differed in patients from distinct units (p = 0.02). The highest number of positive samples was detected in the neonatal pathology and neonatal intensive care units (43.8% each) as well as urology unit (37.9%). The most frequent pathogens belonged to Enterobacteriaceae family, in particular Escherichia coli, Klebsiella spp., Enterobacter spp., and Proteus spp. All studied children (100/100) suffered from intestinal dysbiosis. Titers of Bifidobacterium spp. and Lactobacillus spp. were reduced to 6 (5.0; 8.0) and 5 (4.0; 6.0) lg CFU/g, respectively. In 89.2% children, Escherichia coli lac+ levels were elevated to 9-10 lg CFU/g. Of note, 18.9% children had high Escherichia coli lac- titers [8 (6.0; 9.0) lg] and 24.3% had high Escherichia coli hly+ titers [5 (4.5; 6.0) lg] in the intestine. We have also found a high frequency (44.6%) and density [8.1 (7.0; 8.5) lg] of Klebsiella spp., in the intestinal mucosa of such patients. Notably, Enterobacter spp. and Proteus spp. were abundant [7 (5.0; 8.0) CFU/g] in the intestinal microbiota of 10.8% children. The prevalence of resistance strains in the studied setting reached 63%.Conclusions. More than 75% children with urinary tract infections suffer from intestinal dysbiosis. The microbiome of these patients was predominantly composed of Enterobacteriaceae and was characterized by high titers of Escherichia coli lac+, Klebsiella spp., Enterobacte spp., and Proteus spp. Similar profile of antimicrobial resistance in urinary and intestinal isolates of enterobacteria suggests intestinal microbiome as the main source of pathogens causing urinary tract infections in children.

Aim. To find reliable ultrasound markers of efficient non-pharmacological correction of hypofibrinolysis at preconception period in patients with recurrent pregnancy loss.Materials and Methods. We conducted a single-center, prospective, non-randomized study in patients with recurrent pregnancy loss and hypofibrinolysis (n = 120), who received intermittent pneumatic compression during preconception care. During the pregnancy, we performed a comprehensive 3D ultrasound examination of the endometrium and corpus luteum in the VOCAL mode. Then, we compared patients with (n = 97) and without (n = 23) favorable outcome. Predictive power of the ultrasound parameters was evaluated by a calculation of the area under the receiver operating characteristic (ROC) curve (AUC) and ROC curve comparison.Results. Vascularization flow index of endometrial perfusion (AUC = 0.566) and corpus luteum (AUC = 0.639) was identified as a potential marker of efficient intermittent pneumatic compression at preconception period.Conclusions. Adequate perfusion of endometrium and corpus luteum, reflected by vascularization flow index, may indirectly indicate successful trophoblast invasion and minimize the risk of recurrent pregnancy loss.
Prevention of rabies in Southern Siberia

Published: July 2021

Aim. To substantiate the need for coordinating measures to prevent rabies in adjacent territories with similar conditions for the spread of this infection.Materials and Methods. We retrospectively analyzed spatiotemporal trends in rabies spread during 1950-2020 by studying available statistics from nine Siberian territories (Altai Republic, Altai Region, Tyva Republic, Khakassia, Buryatia, Krasnoyarsk Region, Transbaikal Region, Irkutsk Region and Kemerovo Region). Mapping of rabies cases in humans (n = 124) and animals (n = 1648) was carried out using QGIS 3.16.3, ArcMap 10.8.1 and ArcScene 10.8.1 software and open electronic landscape maps Natural Earth and OpenStreetMap.Results. We revealed two periods of intensive rabies spread in southern Siberia: 1) from 1950 to 1983; 2) from 2002 to the present time. However, human rabies was recorded only during the first period. In all studied territories, inter-epizootic periods lasted from 10 to > 40 years. Geographical analysis identified a mosaic localization pattern and a relative isolation of the affected areas. After 2002, there has been a connection between location of animal rabies cases with agricultural lands and a consistent advance of epizootics from west to east and north-east in all territories, excepting Irkutsk Region. The identified regional features of the spatial distribution of rabies were due to a mountainous terrain and a connection of some forest-steppe areas with similar landscapes of neighboring countries.Conclusions. Southern Siberia is characterized by long rabies-free periods and by the infection foci isolated from other areas as a result of periodic viral invasions from adjacent territories. These features determine the common approaches to the organization of preventive measures across the territories, suggesting their increased efficiency due to the numerous natural barriers and the possibility to concentrate the resources within the small areas. Our results indicate the feasibility of a regional approach to rabies control.

Published: July 2021

The fluoride content in the waters of the Uzh and Latorytsia rivers was assessed (2020, all seasons). The basins of the studied rivers have complex tectonics and geology. It was found that the total content of fluorides in the water of the Uzh River is low (23.7-61.5 μg×L-1) and relatively stable over time. There are no natural and anthropogenic sources of fluoride pollution of river water. Variation of the total content of fluorides in water downstream occurs due to the geochemical characteristics of the river basin. The highest fluoride content is observed near the Uzhhorod city. It is shown that the content of biologically available forms (not chemically bonded) of fluorides in the water of the Uzh River is extremely low (2.2-4.8 μg×L-1). This can lead to fluoride deficiency in the region's residents, who use the Uzh River water as a source of drinking water.
The total content of fluorides in the water of the Latorytsia River varies between 31.4-67.6 μg×L-1, which is to some extent comparable to the content in the Uzh River. Variation of fluoride content along the river is due to the geochemical characteristics of the river basin, the highest fluoride content in the water of the Latorytsia River is observed near Mukachevo city. It was also found that the content of biologically available forms of fluorides in the water of the Latorytsia River is extremely low (2.9-5.6 μg×L-1). Therefore, if the residents of the region use the water of the Latorytsia River as a source of drinking water, fluoride deficiency is possible. In general, the content of fluorides in the river waters of the Transcarpathian region is relatively low. The results of the research will be used for the planning the diet of residents of these regions of Transcarpathia.

Published: July 2021

Abstract
The influences of processing parameters and tool feature on the microstructure of AA1100 and AA3003 aluminium alloys were investigated using bobbin friction stir welding (BFSW). The research includes flow visualization and microstructural evolution of the weld texture using the metallographic measurement method. Results indicated that the operational parameters of the welding (e.g. feed rate, rotating speed) and the geometry of the tool can directly affect the flow patterns of the weld structure. The microscopic details revealed by the optical and electron microscope imply the dynamic recrystallization including grain refinement and precipitation mechanisms within the stirring zone of the weld region. The microscopic observations for the weld samples show a better performance of the fully-featured tool (tri-flat threaded pin and scrolled shoulders) compared to the simple tool without inscribed surface features. The fully-featured tool resulted in a more uniform thermomechanical plastic deformation within the weld structure along with the precipitation hardening and the homogeneity of the microstructure.

Published: July 2021

Abstract
Introduction: Colorectal cancer is one of the most common digestive malignancies, with a high mortality and morbidity rate, with nonspecific symptoms in the early stages and with a diagnosis in the advanced stage most often. In a significant percentage there are cases in which tumors with invasion in the border organs and multiorgan resections are required. In women, the invasion frequently occurs in the vagina, uterus and bladder.
Case report: We report the case of a 52-year-old woman, who presented in the Department of Surgery with the following complaints: fecaluria, pneumaturia, constipation and moderate abdominal pain, with onset of 4 months, in wich the patient neglected her symptoms. Following the investigations, a large tumor formation of sigmoid colon was diagnosed, with invasion in the uterus and bladder, with which it communicates through a 16mm fistula. The result of the biopsy was of low / moderate grade adenocarcinoma differentiated G2. Cystoscopy revealed bladder trigone invasion without being able to identify ureteral orifices, biopsy and urine cytology was also positive for cancer. The surgery was performed by a multidisciplinary team and a multivisceral resection was performed.
Conclusions: Multiorgan resections require trained, experienced teams, and oncological pathology raises special issues when it comes to radical visa. The management of invasive colonic tumors in the border organs must be established preoperatively, in agreement with the patient, because it involves problems related to the quality of life and the potential for survival.
