Published: December 2020

The article presents data assessment of the severity of the clinical condition and a number of biochemical parameters in 51 patients with aneurysmal intracranial hemorrhage on the 10th day, on average, after the rupture of the arterial aneurysm and after treatment with the additional use of magnesium sulfate to standard therapy in the postoperative period. It is shown, that at the time of hospitalization, 75 % of patients in the control group and 50 % of patients in the main group had cerebral vascular spasm according to transcranial dopplerography; activation of lipid peroxidation processes, a decrease in superoxide dismutase activity, an increase in the content of vascular endothelial growth factor and highly sensitive C-reactive protein (CRP) with a decrease in the level of stable nitrogen monoxide exchange products were detected. A statistically significant improvement in the clinical condition of patients on the Hunt-Hess scale, the modified Fisher scale, and an increase in the score on the Glasgow coma scale with normalization of pro- and antioxidant status of the blood were revealed in the main group after neurosurgical treatment and course use of magnesium sulfate. At the same time, high levels of highly sensitive CRP and low levels of nitrates/nitrites in the patients blood of both groups are maintained. Consequently, the additional use of magnesium sulfate improves the clinical condition of patients with intracranial hemorrhage and increases the antioxidant potential of the blood in the postoperative period.

Vitamin D plays an important role in bone metabolism and pathology. Although the VDR gene is one of the most studied determinants of bone mineral density (BMD) and osteoporosis (OP), its exact effects have yet to be established. Prediction of OP and/or fracture risk, based on individual genetic profile, is of high importance. The aim of our study was to develop prognostic model for postmenopausal OP individual risk evaluation in Belarusian women, based on the analysis of VDR gene variants. Case group included women with postmenopausal OP (n = 350), the control group comprised of women with normal BMD and without previous fragility fractures (n = 243). VDR gene ApaI rs7975232, BsmI rs1544410, TaqI rs731236, FokI rs2228570 and Cdx2 rs11568820 variants were determined using TaqMan genotyping assays. We revealed a significant association of single ApaI A/A (p = 0.045), BsmI T/T (p = 0.015) and TaqI G/G (p = 0.005) variants and their A-T-G-haplotype (OR = 4.6, p = 0.003) with increased OP risk. Together with Cdx2 rs11568820, these variants correlated with BMD (p <0.05 in all cases). For the bearers of non-favorable alleles of VDR gene variants, the serum 25(OH)D level was significantly increased. The constructed from informative VDR gene variants model of individual OP risk evaluation possessed a good prognostic value (AUC = 0.79) with high sensitivity level (82.9 %) and average specificity (69.4 %). Our findings highlight the importance of analyzed VDR gene variants for personalized OP risk prediction.

OBJECTIVE
The major concern about ruptured arteriovenous malformations (rAVMs) is recurrent hemorrhage, which tends to preclude stereotactic radiosurgery (SRS) as a therapeutic modality for these brain malformations. In this study, the authors aimed to clarify the role of SRS for rAVM as a stand-alone modality and an adjunct for a remnant nidus after surgery or embolization.

METHODS
Data on 410 consecutive patients with rAVMs treated with SRS were analyzed. The patients were classified into groups, according to prior interventions: SRS-alone, surgery and SRS (Surg-SRS), and embolization and SRS (Embol-SRS) groups. The outcomes of the SRS-alone group were analyzed in comparison with those of the other two groups.

RESULTS
The obliteration rate was higher in the Surg-SRS group than in the SRS-alone group (5-year cumulative rate 97% vs 79%, p < 0.001), whereas no significant difference was observed between the Embol-SRS and SRS-alone groups. Prior resection (HR 1.78, 95% CI 1.30–2.43, p < 0.001), a maximum AVM diameter ≤ 20 mm (HR 1.81, 95% CI 1.43–2.30, p < 0.001), and a prescription dose ≥ 20 Gy (HR 2.04, 95% CI 1.28–3.27, p = 0.003) were associated with a better obliteration rate, as demonstrated by multivariate Cox proportional hazards analyses. In the SRS-alone group, the annual post-SRS hemorrhage rates were 1.5% within 5 years and 0.2% thereafter and the 10-year significant neurological event–free rate was 95%; no intergroup difference was observed in either outcome. The exclusive performance of SRS (SRS alone) was not a risk for post-SRS hemorrhage or for significant neurological events based on multivariate analyses. These results were also confirmed with propensity score–matched analyses.

CONCLUSIONS
The treatment strategy for rAVMs should be tailored with due consideration of multiple factors associated with the patients. Stand-alone SRS is effective for hemorrhagic AVMs, and the risk of post-SRS hemorrhage was low. SRS can also be favorably used for residual AVMs after initial interventions, especially after failed resection.

OBJECTIVEEpilepsy disproportionately affects low- and/or middle-income countries (LMICs). Surgical treatments for epilepsy are potentially curative and cost-effective and may improve quality of life and reduce social stigmas. In the current study, the authors estimate the potential need for a surgical epilepsy program in Haiti by applying contemporary epilepsy surgery referral guidelines to a population of children assessed at the Clinique d’Épilepsie de Port-au-Prince (CLIDEP).METHODSThe authors reviewed 812 pediatric patient records from the CLIDEP, the only pediatric epilepsy referral center in Haiti. Clinical covariates and seizure outcomes were extracted from digitized charts. Electroencephalography (EEG) and neuroimaging reports were further analyzed to determine the prevalence of focal epilepsy or surgically amenable syndromes and to assess the lesional causes of epilepsy in Haiti. Lastly, the toolsforepilepsy instrument was applied to determine the proportion of patients who met the criteria for epilepsy surgery referral.RESULTSTwo-thirds of the patients at CLIDEP (543/812) were determined to have epilepsy based on clinical and diagnostic evaluations. Most of them (82%, 444/543) had been evaluated with interictal EEG, 88% of whom (391/444) had abnormal findings. The most common finding was a unilateral focal abnormality (32%, 125/391). Neuroimaging, a prerequisite for applying the epilepsy surgery referral criteria, had been performed in only 58 patients in the entire CLIDEP cohort, 39 of whom were eventually diagnosed with epilepsy. Two-thirds (26/39) of those patients had abnormal findings on neuroimaging. Most patients (55%, 18/33) assessed with the toolsforepilepsy application met the criteria for epilepsy surgery referral.CONCLUSIONSThe authors’ findings suggest that many children with epilepsy in Haiti could benefit from being evaluated at a center with the capacity to perform basic brain imaging and neurosurgical treatments.

Published: December 2020

Las áreas urbanas generan más escorrentía de aguas pluviales que las áreas naturales, debido a que la impermeabilización de las superficies reduce la infiltración del agua. Ante esto, la tendencia de gestión sostenible de recursos naturales ha generado nuevos enfoques de diseño y planeación urbana que incluyen el uso de sistemas de drenaje innovadores. Por ello, el presente estudio tiene como objetivo determinar la viabilidad para la creación e implementación de los pozos de infiltración como sistema de drenaje pluvial sostenible, a nivel vivienda, en zonas urbanas del municipio de Xalapa, Veracruz, México. Los resultados de viabilidad indican que el interés de las personas en adoptar e invertir en infraestructura para el drenaje pluvial (66.67 %), su bajo costo (75 %), así como las características físicas de las zonas (83 % en zonas estables), juegan un papel muy importante en la aplicación de este tipo de proyectos, sin dejar de lado los beneficios ambientales (91.67 %). Las características técnicas (tipo de suelo, geotecnia, capacidad de infiltración) son prioritarias para el uso de drenaje pluvial alternativo en viviendas de Xalapa. Con ello, la construcción y uso de sistemas de drenaje pluvial alternativo es una medida aplicable a las viviendas del área urbana de Xalapa, por lo que pueden ser un complemento del sistema de drenaje tradicional.
Study of Aluminum Influence on the Adhesion of Stainless Steel in Flame Spraying
Authors: Stepanov Sergey , Larionova Tatyana , Stepanov Sergey 
Published: December 2020

This paper is dedicated to a study of aluminum influence on the improvement of surface adhesion strength. The main purpose of this work is to investigate the strength of adhesion to the substrate by mixing flame spray powder with aluminum, which not only possesses high corrosion resistance and conductivity, but also provides additional strength, as it combines and reacts with other components of the powder.
Research results of sandblasting dependence on surface roughness parameter Ra are demonstrated.
The paper describes authors’ original device for a measuring instrument “Profilometer”, which was also used for measuring roughness parameter in order to obtain comparative results.
Authors present results of adhesion measurements given obtained values of surface roughness by mixing nominal chemical composition of PR-30X13 powder, used as a testing material, with aluminum, which reacts with oxides on the surface of steel substrates, imparts strength to the bonding between the coating and the substrate, protects the base metal due to a combination of chemical components of the powder and creates a layer of dense surface coating. These dependencies are analyzed and parameters, exerting the greatest influence on their values, are identified.
Taking into account the results obtained through numerical modeling, authors propose a mathematical model of a dependency between adhesion strength and certain values of surface roughness for different chemical compositions of flame spray powder. These studies will help in the development of certain material types for spraying and hardening of steel parts and products in order to improve their durability.
Assessment of the Influence of Water Saturation and Capillary Pressure Gradients on Size Formation of Two-Phase Filtration Zone in Compressed Low-Permeable Reservoir

Published: December 2020

The paper examines the influence of capillary pressure and water saturation ratio gradients on the size of the two-phase filtration zone during flooding of a low-permeable reservoir. Variations of water saturation ratio s in the zone of two-phase filtration are associated with the pressure variation of water injected into the reservoir; moreover the law of variation of water saturation ratio s(r, t) must correspond to the variation of injection pressure, i.e. it must be described by the same functions, as the functions of water pressure variation, but be subject to its own boundary conditions. The paper considers five options of s(r, t) dependency on time and coordinates.
In order to estimate the influence of formation and fluid compressibility, the authors examine Rapoport – Lis model for incompressible media with a violated lower limit for Darcy’s law application and a time-dependent radius of oil displacement by water. When the lower limit for Darcy’s law application is violated, the radius of the displacement front depends on the value of capillary pressure gradient and the assignment of s function.
It is shown that displacement front radii contain coefficients that carry information about physical properties of the reservoir and the displacement fluid. A comparison of two-phase filtration radii for incompressible and compressible reservoirs is performed.
The influence of capillary pressure gradient and functional dependencies of water saturation ratio on oil displacement in low-permeable reservoirs is assessed.
It is identified that capillary pressure gradient has practically no effect on the size of the two-phase filtration zone and the share of water in the arbitrary point of the formation, whereas the variation of water saturation ratio and reservoir compressibility exert a significant influence thereupon.
