Authors: Callahan Katharine Press , Flibotte John , Skraban Cara , Wild Katherine Taylor , Joffe Steven , Munson David , Feudtner Chris
Published: February 2022

BACKGROUND AND OBJECTIVES

Genetic testing is expanding among ill neonates, yet the influence of genetic results on medical decision-making is not clear. With this study, we sought to determine how different types of genetic information with uncertain implications for prognosis influence clinicians’ decisions to recommend intensive versus palliative care.

METHODS

We conducted a national study of neonatologists using a split sample experimental design. The questionnaire contained 4 clinical vignettes. Participants were randomly assigned to see one of 2 versions that varied only regarding whether they included the following genetic findings: (1) a variant of uncertain significance; (2) a genetic diagnosis that affects neurodevelopment but not acute survival; (3) a genetic versus nongenetic etiology of equally severe pathology; (4) a pending genetic testing result. Physicians answered questions about recommendations they would make for the patient described in each vignette.

RESULTS

Vignette versions that included a variant of uncertain significance, a diagnosis foreshadowing neurodevelopmental impairment, or a genetic etiology of disease were all associated with an increased likelihood of recommending palliative rather than intensive care. A pending genetic test result did not have a significant effect on care recommendations.

CONCLUSIONS

Findings from this study of hypothetical cases suggest neonatologists apply uncertain genetic findings or those that herald neurodevelopmental disability in problematic ways. As genetic testing expands, understanding how it is used in decision-making and educating clinicians regarding appropriate use are paramount.
A new simple liquid chromatographic assay for gentamicin in presence of methylparaben and propylparaben
Authors: Ivković Branka , Milutinović Ivana , Čudina Olivera , Marković Bojan
Published: February 2022

Gentamicin sulfate is a potent broad spectrum aminoglycoside antibiotic which is used against Gram-positive and Gram-negative bacteria. A simple, isocratic HPLC method for separation, identification and determination of gentamicin and parabens (methylparaben and propylparaben) was developed and validated. To our knowledge there is no report about simultaneous determination of those three analytes in pharmaceutical products. The optimum chromatographic conditions were achieved on CN column with a mobile phase consisting of 0.15% triethylamine in 10 mM KH2PO4 aqueous solution (final pH 3.0 adjusted with H3PO4) and methanol in the ratio 70:30 (v/v), providing selective quantification of analytes within 5 min. The method was successfully validated according to ICH guidelines acceptance criteria in terms of selectivity, linearity, accuracy, precision and robustness. The linearity of the method was proved in defined concentrations ranges for gentamicin (0.32–1.04 mg mL−1), methylparaben (0.0072–0.0234 mg mL−1) and propylparaben (0.0008–0.0026 mg mL−1). Relative standard deviations calculated for all analytes in precision testing were <2% (analysis repeatability) and <3% (intermediate precision). Recovery values were between 98.87% and 101.67%. Chromatographic parameters are not significantly influenced by small variations of column temperature, pH and molarity of KH2PO4. Finally, the method was successfully applied for quantitative determination of gentamicin and parabens in commercially available solution for injection. Proposed HPLC method is found to be promising in terms of simplicity, analysis times and non-use of derivatization and ion-pair agents.
Influenza elleni védőoltás: mi szól mellette és ellene?

Published: February 2022

Összefoglaló.
Bevezetés: A magyar felnőtt lakosság heterogén attitűdje
folytán az influenza elleni átoltottság elmarad az nemzetközi ajánlásoktól. A
háziorvosok meggyőző potenciálja jelentős, ezért fontos szerepük van a felnőtt
lakosság oltással kapcsolatos döntéseinek befolyásolásában.
Célkitűzés: Az influenza elleni oltásra vonatkozó támogató
és akadályozó tényezők azonosítása felnőtt háziorvosok és a teljes lakosság és
körében. Módszer: 1000 fő, a teljes felnőtt lakosságra
reprezentatív alany, valamint 317 fő, felnőtt- és vegyes praxisban dolgozó
háziorvosokra reprezentatív orvos megkérdezése önkitöltős online kérdőív
segítségével. Eredmények: Az influenza elleni oltás lehetősége
93%-ban ismert a lakosság számára, 30% a leginkább a háziorvos tanácsát követné
ebben a kérdésben. A háziorvosok jelentősen túlbecsülik az ellátott lakosság
átoltottságát. Az oltást nem tervezők leggyakoribb indokai: nem tartják
veszélyesnek az influenzát, bíznak a saját immunrendszerükben, tartanak az oltás
mellékhatásaitól. Megbeszélés: Elenyésző az influenza elleni
oltás lehetőségét mereven elutasítók aránya. A többség relatív indokok alapján
tartja kevésbé fontosnak ezt a lehetőséget. A háziorvos hiteles szereplő a
lakosság jelentős része számára. Következtetés: A háziorvos
szerepe kulcsfontosságú a lakosság átoltottságának növelésében. Orv Hetil. 2021;

Summary.
Introduction: Compared to the international guidelines, the flu
vaccination rate of the Hungarian adult population is not satisfactory due to
its heterogeneous attitude towards vaccination. Based on previous results, the
convincing potential of general practitioners seems to be significant, therefore
they have an important role when influencing people’s decision-making concerning
this topic. Objective: To identify drivers and barriers to flu
vaccination among general practitioners and the whole population.
Method: Adult subjects representing the whole general
population (n = 1000), and a representative sample of general practitioners (n =
317) surveyed through online self-completed questionnaires.
Results: 93% of the adult population is aware of influenza
vaccine’s existence. 30% prefer to follow the general practitioner’s advice on
this topic. General practitioners significantly over-estimate the vaccination
coverage of the population they serve. The most common reasons for not getting
vaccinated against flu: not considering the influenza dangerous, trusting their
own immune system, and being afraid of the side effects of the vaccine.
Conclusion: The rate of hard refusal of influenza
vaccination is negligible. The vast majority of the population consider this
option less important for relative reasons. The general practitioner is an
authentic actor for a large part of the population. Orv Hetil. 2022; 163(6):

Driving Zn-MnO2 grid-scale batteries: A roadmap to cost-effective energy storage
Authors: Spoerke Erik D. , Passell Howard , Cowles Gabriel , Lambert Timothy N. , Yadav Gautam G. , Huang Jinchao , Banerjee Sanjoy , Chalamala Babu
Published: February 2022

Highlights

Zn-MnO2 batteries promise safe, reliable energy storage, and this roadmap outlines a combination of manufacturing strategies and technical innovations that could make this goal achievable. Approaches such as improved efficiency of manufacturing and increasing active material utilization will be important to getting costs as low as $100/kWh, but key materials innovations that facilitate the full 2-electron capacity utilization of MnO2, the use of high energy density 3D electrodes, and the promise of a separator-free battery with greater than 2V potential offer a route to batteries at $50/kWh or less.

Large-scale energy storage is certain to play a significant, enabling role in the evolution of the emerging electrical grid. Battery-based storage, while not a dominant form of storage today, has opportunity to expand its utility through safe, reliable, and cost-effective technologies. Here, secondary Zn–MnO2 batteries are highlighted as a promising extension of ubiquitous primary alkaline batteries, offering a safe, environmentally friendly chemistry in a scalable and practical energy dense technology. Importantly, there is a very realistic pathway to also making such batteries cost-effective at price points of $50/kWh or lower. By examining manufacturing examples at the Zn–MnO2 battery manufacturer Urban Electric Power, a roadmap has been created to realize such low-cost systems. By focusing on manufacturing optimization through reduced materials waste, scalable manufacturing, and effective materials selection, costs can be significantly reduced. Ultimately, though, coupling these approaches with emerging research and development advances to enable full capacity active materials utilization and battery voltages greater than 2V are likely needed to drive costs below a target of $50/kWh. Reaching this commercially important goal, especially with a chemistry that is safe, well-known, and reliably effective stands to inject Zn–MnO2 batteries in the storage landscape at a critical time in energy storage development and deployment.

ANDROID SOFTWARE AGING AND REJUVENATION MODEL CONSIDERING THE BATTERY CHARGE
Authors: Yakovyna V. S. , Uhrynovskyi B. V.
Published: February 2022

Context. A feature of mobile systems is their dependence on battery charge, which is an important factor when planning various processes, in particular when planning time of performing software rejuvenation procedure.

Objective. The goal of this article is to develop a model of software aging process with performing rejuvenation procedure for the Android operating system considering the factor of battery charge.

Method. A complex model based on Continuous-Time Markov Chains is proposed, which combines the software aging and rejuvenation model, the user behavior model and consider battery charge factor. A graph of states and transitions describing a complex model is constructed. Based on the formed graph the system of differential equations is written. The system was calculated using the 4th order Runge-Kutta method. The optimal time for the rejuvenation procedure can be determined when rejuvenation will not interfere with the user and will be performed before the battery is fully discharged, ie when the probability of the system being in these states is the lowest.

Results. The simulation of the developed model for test values of transition rates is performed. Considering the battery charge model allows to avoid planning the rejuvenation procedure at a time when the mobile device is likely to have a low charge or be completely discharged.

Conclusions. The proposed model based on the Markov chain allows to predict the start time of software rejuvenation procedure, considering both user behavior and battery level, which can have a significant impact on the predicted time. Also, the early implementation of the rejuvenation procedure may have the effect of reducing the system workload and delaying the discharge of the device, which should be checked in further studies. The expediency and importance of the consideration of battery charge factor and the need for further study of the proposed software aging and rejuvenation model are substantiated.

Eugênio Gudin: As Controvérsias do Neoliberalismo Caboclo
Authors: BORGES MARIA ANGÉLICA
Published: February 2022

RESUMO Este artigo examina a produção teórica de Eugênio Gudin que expressa sua nova postura liberal, que destaca sua oposição a Roberto Simonsen, a teoria do desenvolvimento econômico do Cepal, Marx e seus seguidores. Gudin reconheceu Karl Marx como o maior inimigo do capitalismo. Ele atribuiu ao pensador a criação do conceito de capitalismo com conotações históricas. Negando radicalmente esse conteúdo e equilibrando a concepção do caráter natural e eterno desse sistema, ele se concentrou no capitalismo como um sistema de produção que se conecta harmonicamente à democracia. Ele trabalhou com o par de conceitos: economia, mercado e democracia como antítese do planejamento e do totalitarismo, estruturando o discurso que enfatiza o plano geral abstrato, desconsiderando uma análise histórica concreta de cada caso específico. Consequentemente, todo aspecto que não se encaixa nesse par é considerado antidemocrático e intervencionista, como uma negação equivalente ao ideal humano, às vezes que deve ser evitado ou mesmo destruído.
Intentando Hacer Grietas en el Sistema Educativo Mexicano: los contrapuntos en los aprendizajes de los estudiantes de la Licenciatura en Planeación del Desarrollo Rural del Centro de Estudios para el Desarrollo Rural (CESDER) en la Sierra norte de Puebla

RESUMEN En el presente documento se estudia un modelo de educación superior alternativo y genuino que auspicia de manera sostenible procesos de aprendizaje a través de las experiencias vividas por los estudiantes de la carrera de Planeación del Desarrollo Rural en el Centro de Estudios para el Desarrollo Rural (CESDER), localizado en la Sierra norte de Puebla. Para tal efecto, se empleó el enfoque etnográfico a partir de entrevistas in situ en la que cada uno de los siete estudiantes (tres mujeres y cuatro hombres) describieron cómo han sido sus aprendizajes, las experiencias en su institución educativa y cómo influyeron estos procesos en sus modos de vida. También se realizaron entrevistas en profundidad con dos docentes del CESDER quienes describieron la filosofía de trabajo asumida en esta casa de estudios. Se concluye que la educación bajo el enfoque que le imprime el CESDER sí ha influido en sus modos de vida porque las experiencias de campo reflexionadas de manera crítica en el aula se interrelacionan con las perspectivas docentes y con los saberes de los campesinos para generar comunidades de aprendizaje situado.
Correlating groundwater level and shear strength: Kotkai Pakistan landslide as case study
Authors: Khan Muhammad Israr , Wang Shuhong
Published: February 2022

Earth-fill dam failure and landsliding during heavy rainfall and flooding is a common problem observed all over the world. This paper examines and discusses the causes of landsliding due to rainfall and flooding. Climatic rainfall data are interconnected with rainfall precipitation and its effect on the increase in pore water pressure inside soil slopes. Various soil slopes with different geometries and material properties are analysed, and the variation in pore water pressure and the slope factors of safety (FSs) are calculated. Correlations between the groundwater level (GWL) and slope FS are developed in both seismic and non-seismic situations. Correlations between shear strength (τ), shear stress (σ) and FS are also developed. The Kotkai landslide in Pakistan is considered a case study for cross-checking the correctness of the developed correlations. These correlations can be applied to design a safe soil slope in intense flood and rainfall areas.
An integrative description of a new Richtersius species from Greece (Tardigrada: Eutardigrada: Richtersiusidae)
Authors: Pogwizd Justyna , Stec Daniel
Published: February 2022

In this paper, we describe a new tardigrade species, Richtersius tertius sp. n., from Greece. The description is based on morphological and morphometric analysis using light and scanning electron microscopy as well as genetic analysis based on four molecular markers (DNA sequences of three nuclear, i.e., 18S rRNA, 28S rRNA, ITS-2 and one mitochondrial COI fragment). Morphological and morphometric differences, together with genetic comparisons, provide independent verifications of Richtersius tertius sp. n. as a species new to science. Phenotypically, the new taxon differs from Richtersius coronifer (Richters, 1903) and Richtersius ziemowiti Kayastha, Berdi, Miaduchowska, Gawlak, Łukasiewicz, Gołdyn, Jędrzejewski et Kaczmarek, 2020 mainly by the morphology and size of cuticular pores, present only in hatchlings (first instars), as well as some morphometric characters. The results presented herein contribute further to the recognition of the morphological variability and biodiversity within Richtersius, with Richtersius tertius sp. n. being the third species formally described within the genus.

Los libros álbum radicales en contextos educativos: una revisión sistemática sobre propósitos, competencias y relaciones entre mediadores y lectores
Authors: Véliz Soledad
Published: February 2022

A pesar de las expectativas que han generado los libros radicales, no se ha sistematizado el aporte de estos respecto a sus propósitos, las competencias que promueven en los lectores y las interacciones que abren entre mediadores de la lectura (adultos) y lectores infantiles y juveniles. Este artículo pretende llenar este vacío presentando una revisión bibliográfica sistemática de 36 artículos empíricos que reúnen evidencia sobre el trabajo que se está llevando a cabo con libros álbum agrupados bajo la denominación de “radicales” en contextos educativos. Se entiende por “libros radicales” aquellos libros álbum que contiene una sofisticación narrativa (libros postmodernos), temáticas poco convencionales para la literatura infantil (inquietantes) y una producción editorial crossover o para todas las edades. El análisis categorial inductivo revela tres aspectos importantes: a) que los libros radicales son apreciados por producir brechas entre imagen y texto, lo que promueve la construcción de significado diverso en los lectores; b) que la investigación en esta área se enfoca en la promoción de competencias socioemocionales y de literacidad crítica, y c) que el uso de estos libros puede abrir relaciones más simétricas entre mediadores y lectores.

Published: February 2022

Migratory locust, Locusta migratoria (Acrididae: Orthoptera) is a serious oligophagous pest of agriculture, found mostly in African, Asian and Australian continents. A bacterium isolated from eggs of L. migratoria was identified as Bacillus cereus CSBRLE2. The pathogenic effects of B. cereus on development and various tissues and haemolymph protein in L. migratoria have been investigated. Third instar nymphs were starved and inoculated with 10 ìl of bacterial suspension having concentration of 8x108 cfu/ml. The individuals were maintained in the laboratory up to adult maturation and egg laying. Body weight of the B. cereus inoculated individuals significantly reduced as compared to control. High mortality and lower fecundity and hatching percentage observed in the groups inoculated with bacterium. Inoculation of bacteria reduced the total haemolymph protein in  adults as compared to control. The present study demonstrates that B. cereus could be used against L. migratoria in combination with other viable agents to help in management of locust and grasshoppers population in the field.

Studies were conducted under laboratory conditions to evaluate the food consumption and nutritional indices for the development of Antheraea proylei larvae fed on Quercus glauca. Larval duration was 5.4±0.489, 6.4±0.48, 7.2±0.4, 9.8±0.74 and 14.2±0.74 days in the 1st, 2nd, 3rd, 4th and 5th instars, respectively. Larvae consumed a total of 28.85 g insect– ¹ day– ¹, egested 4.164 g insect– ¹ day– ¹ and assimilated 24.69 g insect– ¹ day– ¹ of food  provided. 82.3% of tissue growth was observed in the 4th and 5th instar larvae. Approximate digestibility (AD) decreased from 91.94% in the first instar larva to 80.79% in the 5th instar larva. Efficiency of conversion of digested food (ECD) into body tissue and efficiency of conversion of ingested food into growth (ECI) increased from 1st instar larva to 5th instar larva. The result obtained in the present study indicate that Q. glauca could serve as an alternate host plant for rearing A. proylei in areas where the main host plant Q. serrata is not found.

The study aimed to evaluate the immediate results of the use of electret in the surgical treatment of children with Perthes disease.
Material and Methods. The study was based on the results of a comprehensive examination of 10 patients (10 hip joints; average age, 7.20.7 years). To stabilize the joint and comply with the principle of containment therapy, all children underwent triple pelvic osteotomy, which was supplemented by a transphyseal implantation electret. Postoperatively, all patients were evaluated for the severity of pain syndrome and amplitude of movements and underwent ultrasonography, radiometry of the main indicators of the structure and stability of the hip joint, computed tomography, and magnetic resonance imaging of the hip joints.
Results. The visual analog scale questionnaire indicated the presence of a moderately pronounced pain syndrome on postoperative day 3, with its complete relief by day 7. Ultrasound studies showed the absence of synovitis, and goniometry revealed the achievement of physiological indicators of flexion and abduction to the end of the hospitalization period. According to the radiation methods, all patients had elimination of subluxation with the restoration of hip joint stability and a significant improvement in the shape of the femoral head with the appearance of its single bone contour. The volume of the bone part of the femoral head increased by 15%35% from the original, and there was a significant improvement in the shape of the cartilaginous model with the complete absence of a necrosis focus in the femoral head, close to the physiological position of the labrum acetabulum.
Conclusion. The use of electret in the surgical treatment of children with Perthes disease in Catterall groups IIIIV and hip subluxation due to the anti-inflammatory effect makes it possible to alleviate pain syndrome and manifestations of synovitis early after surgery and to begin rehabilitation treatment with the achievement of the physiological amplitude of movements in the hip joint in the immediate postoperative period. The osteoreparative effect of the electrostatic electret field alone or in combination with anti-inflammatory treatment increased the volume of the newly formed bone tissues of the femoral head with a decrease in the area of its defect or disappearance of compression of the central part of the epiphysis with the differentiation of the initial elements of the trabecular pattern, in comparison with the homogeneous high-intensity structure of the femoral head.
Consistency of Non-Double-Couple Components of Seismic Moment Tensors with Earthquake Magnitude and Mechanism
Authors: Rösler Boris , Stein Seth
Published: February 2022

Earthquake moment tensors can be decomposed into double-couple components describing slip on planar faults and non-double-couple (NDC) components. NDC components can arise in three ways. Some appear to be intrinsic, indicating complex source processes differing from slip on a fault for earthquakes in specific geologic environments, notably volcanic areas. Others are additive, reflecting the combined effect of double-couple sources on multiple faults with different geometries. Alternatively, they may be artifactual, results of the inversion without geologic meaning. Combining moment tensors from three global and four regional catalogs for 2016–2020 provides a dataset of NDC components of 12,856 earthquakes with 2.9<Mw<8.2 in various geologic environments. The distributions of NDC components vary only slightly with magnitude, with a mean deviation from a double-couple source of around 20%. The consistency suggests that most NDC components do not reflect rupture on multiple faults, which is expected only for larger earthquakes. Similarly, there are only small differences in NDC components between earthquakes with different faulting mechanisms or in different geologic environments. These consistencies suggest that most NDC components are not intrinsic due to complex source processes that are often assumed to be most likely in volcanic and thus extensional areas. Hence, it appears that for most earthquakes, especially smaller ones, the NDC components are largely artifacts of the inversion.

The dynamic properties of freestanding rock towers are important inputs for seismic stability and vibration hazard assessments, however data describing the natural frequencies, mode shapes, and damping ratios of these landforms remain rare. We measured the ambient vibration of 14 sandstone and conglomerate rock towers and fins in Utah, United States, using broadband seismometers and nodal geophones. Fundamental frequencies vary between 0.8 and 15 Hz—inversely with tower height—and generally exhibit subhorizontal modal vectors oriented parallel to the minimum tower width. Modal damping ratios are low across all features, between 0.6% and 2.2%. We reproduced measured modal attributes in 3D numerical eigenfrequency models for 10 of the 14 landforms, showing that the fundamental mode of these features is full-height bending akin to a cantilever. Fin-like landforms commonly have a torsional second mode whereas tower-like features have a second full-height bending mode subperpendicular to the fundamental. In line with beam theory predictions, our data confirm that fundamental frequencies scale with the ratio of a tower’s width to its squared height. Compiled data from 18 other sites support our results, and taken together, provide guidance for estimating the modal properties of rock towers required for vibration risk assessment and paleoseismic shaking intensity analysis in different settings.

Published: February 2022

Aim      To evaluate the diagnostic capacity of left ventricular (LV) postsystolic shortening (PSS) values obtained by speckle-tracking stress-echocardiography (stress-EchoCG) using a treadmill test in determining the functional significance of the degree of coronary artery (CA) stenosis.

Material and methods  The study included 132 patients (80 men aged 65.0±9.3 years) with suspected or previously verified diagnosis of ischemic heart disease. Stress-EchoCG with the treadmill test was performed for all patients. Strain parameters were determined by two-dimensional speckle-tracking on gray-scale images before and after the exercise. Values of LV postsystolic index (PSI) and LV mean postsystolic time (PST) were calculated. Coronary angiography was performed for all patients. Patients were divided into 3 groups based on the severity of CA stenosis according to the G. G. Gensini score.

Results LV PSS values at rest did not significantly differ between the patient groups. After completion of the exercise, the mean LV PSI was significantly higher for patients with pronounced CA stenosis than in the group without CA stenosis or with moderate CA stenosis: 8.9 %  [3.8; 10.7 %] vs. 3.8 % [2.2; 6.8 %] (p=0.012) and 3.4 %  [2.2; 6.2 %] (p=0.012), respectively. The mean LV PSI after completion of the exercise indicated the presence of pronounced CA stenosis with a sensitivity of 75 % and a specificity of 61 % (area under the curve, AUC, 0.74±0.06; р<0.001). After completion of the exercise, the mean LV PST was significantly greater for patients with pronounced CA stenosis than in the group without CA stenosis or with moderate CA stenosis: 27.4 [18.7; 34.7] ms vs. 18.4 [10.8; 26.5] ms (p=0.036) and 20.9 [14.2; 29.5] ms (p=0.036), respectively. The mean LV PST after completion of the exercise exceeding 23.5 ms suggests pronounced CA stenosis with a sensitivity of 71 % and a specificity of 65 % (AUC 0.69±0.06; p=0.004). A complex evaluation of the LV PSI, the LV local contractility disorder (LCD) index, the LV PST, and LV LCD index allows enhancement of the test sensitivity in diagnozing pronounced CA stenosis.

Conclusion      Determination of LV PSS in speckle-tracking stress-EchoCG may be useful for evaluating the functional significance of the degree of CA stenosis to enhance the sensitivity of stress-EchoCG in patients with pronounced CA stenosis.
