Authors: Akhatova Z. A. , Musin R. S. , Vlasov P. N. , Trukhanov S. A. , Makarova Yu. I.
Published: August 2022

Introduction. The incidence of stroke is 2.5–3 cases per 1 000 population per year, mortality – 1 case per 1 000 population per year. According to various data, up to 20% of computed tomography (CT) scans performed on the first day do not reveal signs of  an ischemic focus.

Aim of the study. To assess the detectability of acute ischemia foci using CT, depending on the location of the foci, the timing of  neuroimaging, the severity of stroke, and other indicators.

Material and methods. We analyzed 100 cases of acute cerebrovascular accident (ACV) by ischemic type. The timing of the CT scan, glucose level, coagulogram parameters, NIHSS scores at admission, focus localization, the presence of atherosclerosis of the arteries of the head, and atrial fibrillation were taken into account. Patients were divided into two groups depending on the fact of detection of the focus during the primary tomographic examination. Repeated neuroimaging (magnetic resonance imaging) was performed in 54 patients.

Results. In the “CT-negative” group, stem strokes predominated (p = 0.01), patients were younger (р = 0.038), and there were significantly more women than men (р = 0.00006). An increase in glucose over 8 mmol/l, on the contrary, was more often detected in the “CT-positive” group (14 cases in “CT-positive” against 5 cases in “CT-negative” group, p = 0.022). NIHSS scores ≥ 5 were found in 24 patients (47%) in the “CT-positive” group and in 13 patients (26.5%) in the “CT-negative” group (p = 0.034).

Conclusions. Cases of stroke that are not detected on CT scan upon admission to the hospital are more common among women, with stem localization, are associated with low NIHSS scores. High glucose levels at admission is associated with the detection of ischemic foci during the initial CT examination.

Taurine is a sulfur-containing amino acid. Taurine is necessary for the conjugation of bile acids, has antioxidant, anti-inflammatory properties, acts as an anti-apoptotic factor; cell membrane stabilizer; regulator of Ca2+ signaling, fluid homeostasis in cells, retinal photoreceptor activity; contributes to osmoregulation and conduction in the nervous and muscular systems; a neurodevelopmental stimulant; and an inhibitory neurotransmitter in the central nervous system. Taurine is not only synthesized from cysteine and methionine, but also comes from food. Taurine intake is 40–400 mg/day. The main food sources are animal products: shellfish, fish, meat. Taurine is part of breast milk and adapted milk formulas for the nutrition of young children. Under stress and some diseases, the endogenous synthesis of taurine is reduced. The risk groups for taurine deficiency include people who follow a vegetarian diet and observe religious fasts. There are a number of products in which taurine is added: specialized food products (SF) and food supplements (FS) contain 60–1200 mg of taurine per serving, energy drinks – 300–400 mg per 100 ml. The clinical effects of taurine in diabetes mellitus, heart failure are manifested when it is included in diet therapy in doses of 1.5–3 g for  2–16 weeks. Even the maximum doses allowed for use as part of SFP and dietary supplements are significantly less than the doses that ensure the achievement of a clinical effect, which does not guarantee the expected result when using SF.

The synthesis of ZnO-MgO nanocomposite via modified Pechini method was performed. The crystalline structure and the morphology of nanocrystals were studied by X-ray diffraction analysis and scanning electron microscopy. The study on the kinetics of diazo dye adsorption and its photocatalytic decomposition on the surface of nanocomposite was performed. It was shown that the rate of adsorption process in aqueous solution is described by a kinetic equation of the first order. The application of the nanocomposite allows to significantly increase the efficiency of UV water treatment and its purification from the dye. However, a brief deviation of experimental data on the rate of photocatalytic degradation from the values of the widely used kinetic equation of the first order is observed.

In learning mathematics, understanding concepts is very important for students because understanding is the most basic ability that students must have in the learning process. The low ability of students' understanding of mathematical problems because mathematics learning is still teacher-centered. The use of conventional learning models which resulted in low understanding abilities and learning outcomes. Therefore, teachers should be able to use learning models, one of which is learning by applying the Scaffolding method. The purpose of this study was to improve students' ability to operate algebra using the Scaffolding method. This research method is descriptive quantitative. The population of this study were students of class VII-1 and VII-2 of SMP Negeri 2 Banda Aceh. The research sample used was 6 students; 3 students in class VII-1 and 3 students in class VII-2. The data analysis technique used is descriptive statistics. While the data collection techniques in the form of observation and test data; pretest and posttest. The results showed that the score before the use of the Scaffolding method and after the use of the Scaffolding method respectively was 61.00 to 89.67 which means that the average score of students increased by 47%. Based on these values, it is concluded that the application of the Scaffolding method can improve students' algebraic operation skills.
Perinatal hypoxia as a risk factor for a more severe lexical-semantic deficit in children with developmental language disorder
Authors: Drljan Bojana , Jecmenica Nevena
Published: August 2022

Background/Aim. There is a small body of literature on the influence of perinatal hypoxia (PH) on language outcomes at a later age. Correspondingly, there are no studies on the influence of PH on the extent and severity of language deficits in children with developmental language disorder (DLD). The aim of this study was to examine the differences in lexical-semantic (LS) abilities in DLD children with the presence of PH (DLDph) and DLD children without any neurological risk factors (DLDwnrf). Methods. The study sample consisted of 96 children aged 5 to 8 years, divided into three groups: 25 children in the DLDph group, 30 children in the DLDwnrf group, and 41 typically developing (TD) peers. To compare age-related differences, an additional categorical variable was formed with two age groups ? preschool and school-age children (5?6 and 7?8 years, respectively). LS abilities were investigated with specific measures for assessing the expressive vocabulary (EV) size, semantic processing (SP) skills, and lexical productivity (LPr). To assess LPr, measure for calculating lexical diversity from speech sample was applied. Results. Significant differences were observed between DLDph and DLDwnrf children on the SP assessment (p < 0.05) but not on the EV (p = 0.350) and LPr (p = 0.118) assessment. However, a detailed analysis of developmental tendencies between preschool and early school-age children showed that DLDph children progressed significantly only in the domain of EV (p < 0.01), while DLDwnrf children progressed significantly in the domain of EV and SP skils (p < 0.001). Regarding LPr developmental tendencies, no significant progress was observed in either of the DLD groups. Conclusion. In DLDph children, a more severe extent of LS deficit in the area of SP abilities can be related to PH. Similarly, PH can contribute to slower progress in a wider spectrum of LS abilities.

Published: August 2022

Objectives

To evaluate the effect of friction vs frictionless mechanics on the rate of anterior segment retraction (ASR) in patients with bimaxillary protrusion.

Materials and Methods

Thirty females (18.3 ± 3.7 years) with bimaxillary protrusion were randomly allocated into the friction group, using elastomeric power chains, and the frictionless group, using T-loop springs for ASR. Eligibility criteria included absence of skeletal discrepancies and any systemic diseases or medications, among others. Randomization in a 1:1 ratio was generated by Microsoft Excel. Opaque sealed envelopes were sequentially numbered for allocation concealment. Only blinding of the outcome assessor was applicable. Activations were done every 4 weeks until completion of ASR. The primary outcome was the rate of ASR measured on digital models. Anchorage loss, molar rotation, and pain experienced were also assessed.

Results

Two patients were lost to follow-up. The rate of ASR was 0.68 ± 0.18 mm/mo in the friction group vs 0.88 ± 0.27 mm/mo in the frictionless group, with no significant difference. A significant difference in anchorage loss of 1.63 mm and molar rotation of 7.06° was observed, being higher in the frictionless group. A comparable pain experience associated with both mechanics was reported.

Conclusions

No difference in the rate of ASR or pain experience was observed between friction and frictionless mechanics. However, extra anchorage measures should be considered when using frictionless mechanics as greater anchorage loss and molar rotations are anticipated.

Family businesses are one of the most popular form of economic organizations, known for their agility and resilience to the external environment. Despite this, many family businesses have faced enormous challenges related to the covid-19 crisis, straining the emotional and physical well-being of family members as well as non-family employees. In this research work, we focus on how the pressures of the crisis influence the non-economic goals of family firms, in particular their ability to preserve their socio-emotional wealth. Based on the five dimensions of socio-emotional wealth. We found that the ability to adapt to these new circumstances has become essential to preserve their socio-emotional wealth and this can be done through good communication, transparency, maintaining positive emotions, developing trusting relationships and anticipating sudden successions.

As Feiras de Ciências em Roraima (1986 A 2008) Contribuição para a Iniciação à Educação Científica
Authors: Sousa Maria do Socorro Magalhães de , Rizzatti Ivanise Maria
Published: August 2022

As Feiras de Ciências são importantes espaços para a iniciação científica de estudantes da Educação Básica. Além da formação científica, as Feiras de Ciências permitem aos estudantes um espaço para troca de informações, construção de relações sociais, socialização de experiências, além do convívio comunitário. Ademais, a Feira de Ciências, quando interpretada como um espaço não-formal de ensino e educação, apresenta imensurável potencialidade para práticas docentes diferenciadas e inovadoras. Neste contexto se insere a Feira Estadual de Ciências de Roraima (FECI-RR), que teve sua primeira edição em 1986. E nestes 30 anos de existência, observa-se uma crescente participação das escolas e dos alunos da capital e do interior do estado a cada edição, com a inserção de escolas da área urbana, rural e indígena, com exposição dos trabalhos desenvolvidos no âmbito escolar e voltados para a realidade local. Dessa forma, torna-se importante resgatar a história das Feiras de Ciências de Roraima e sua importância para iniciação científica em Roraima. Um estado que ainda possui baixos indicadores educacionais e apresentam dados preocupantes no que se referem aos resultados da avaliação de desempenho do estudante apresentados nos exames nacionais que são aplicados no final do Ensino Básico. O índice em 2013, disponibilizado pelo INEP (Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira), ficou abaixo da meta projetada de 3.8, alcançando 3.2, demonstrando apreensão nos educadores que buscam alternativas para melhorar o aprendizado de seus alunos. A consequência desse quadro reflete no perfil do ingressante na Educação Superior provocando questionamentos sobre a trajetória escolar desse aluno. Alcançar uma educação de qualidade é tarefa fundamental para assegurar o desenvolvimento de todo país e região, o que não é diferente no estado de Roraima que luta por melhorar os indicadores que avaliam essa qualidade. E as feiras científicas escolares juntamente com a Feira Estadual de Ciências podem contribuir com a elevação destes indicadores, uma vez que oferta cursos para a formação continuada de professores e envolve os estudantes num ambiente de pesquisa em Institutos de Ensino e Pesquisa de Roraima. Nesta direção, esta obra vem contribuir para este resgate histórico e valorização da pesquisa na Educação Básica de Roraima, auxiliando com o desafio de buscar essas informações e mostrar a contribuição das feiras de ciências para o processo de iniciação à Educação Científica roraimense.

Background. An effective treatment for renal cell carcinoma complicated by tumor thrombus (TT) is nephrectomy with thrombectomy (NETE) from the inferior vena cava (IVC), which is associated with massive blood loss, high morbidity and mortality. The study aims to evaluate the infusion-transfusion protocol (ITP) for NETE from the IVC without extracorporeal circulation.
Materials and methods. The observational single-center study included 682 patients who were operated for NETE for renal cell carcinoma with TT. Patients were divided into 3 groups depending on the level of TT according to the Mayo classification. The InfraHepatic (InH) group included patients with TT levels I and II, the RetroHepatic (RH) group included patients with TT level III, and the SupraDiaphragmatic (SD) group included patients with TT level IV. Own concept of moderately advanced infusion in the amount of 130140% of all losses were introduced. Qualitative and quantitative composition of ITP, frequency of use of sympathomimetics, complications and mortality were assessed.
Results. The rate of massive blood loss was 46.9% in the InH group, 74.7% in the RH group, and 86.3% in the SD group. ITP was characterized a significant increase in the absolute values of all infusion media, a decrease the proportion of crystalloids and colloids, an increase the proportion fresh frozen plasma, donated erythrocytes, and proportion of auto-erythrocytes between groups. The frequency of using intraoperative cell salvage in the InH group was 39.6%, in the RH 67.7%, in the SD 90.7%. The greatest hemodynamic shifts were recorded in the SD group. The frequency of postoperative complications was 24.3%, and hospital mortality was 7% with accordance to the ITP, adequate hemodynamic and laboratory monitoring in NETE. Low mortality due to hemorrhagic shock in our study (0.15%) emphasizes the effectiveness of the presented ITP.
Conclusion. The obtained data demonstrate the results of NETE as comparable with those presented in the available literature.
Cancer-associated thrombosis during chemotherapy: treatment and prevention: A review
Authors: Koroleva Irina A. , Kopp Mikhail V.
Published: August 2022

Cancer-associated thrombosis is a significant problem today for both oncologists and vascular surgeons. In patients with malignant neoplasms the incidence of symptomatic venous thromboembolism (VTE) is 47 times higher than in the general population. The presence of distant metastases in solid tumors increases the risk of VTE. Most often, VTE develop in pancreatic cancer and stomach cancer. Chemotherapy increases the risk of developing VTE. Low-molecular-weight heparin and direct oral anticoagulants are used for the treatment of VTE in patients with chemotherapy. The results of the СARAVAGGIO study demonstrated that apixaban is not inferior to dalteparin in the treatment of VTE in patients with active cancer and does not increase the risk of bleeding. Before starting chemotherapy, it is necessary to assess the risk of developing VTE using the Khorana risk score. Outpatient patients with high-risk cancer (Khorana score 2 before the start of a new systemic chemotherapy regimen) may be prescribed thromboprophylaxis with low molecular weight heparin. The idea of using direct oral anticoagulants seems promising, but so far it is beyond the scope of approved indications.
A Unified Framework to Estimate Macroeconomic Stars
Authors: Zaman Saeed
Published: August 2022

We develop a flexible semi-structural time-series model to estimate jointly several macroeconomic "stars" -- i.e., unobserved long-run equilibrium levels of output (and growth rate of output), the unemployment rate, the real rate of interest, productivity growth, price inflation, and wage inflation. The ingredients of the model are in part motivated by economic theory and in part by the empirical features necessitated by the changing economic environment. Following the recent literature on inflation and interest rate modeling, we explicitly model the links between long-run survey expectations and stars to improve the stars' econometric estimation. Our approach permits time variation in the relationships between various components, including time variation in error variances. To tractably estimate the large multivariate model, we use a recently developed precision sampler that relies on Bayesian methods. The by-products of this approach are the time-varying estimates of the wage and price Phillips curves, and the pass-through between prices and wages, both of which provide new insights into these empirical relationships' instability in US data. Generally, the contours of the stars echo those documented elsewhere in the literature -- estimated using smaller models -- but at times the estimates of stars are different, and these differences can matter for policy. Furthermore, our estimates of the stars are among the most precise. Last, we document the competitive real-time forecasting properties of the model and, separately, the usefulness of stars' estimates as steady-state values in external models.
Critical Race Theory and the Law in New Zealand
Authors: Asafo Dylan , Tuiburelevu Litia
Published: August 2022

To respond to the enduring need for a reckoning with racism in New Zealand through legal scholarship and praxis, this article grapples with the question: how can we adopt a Critical Race Theory (CRT) framework that is located within, and appropriate for, the New Zealand context? Our central thesis is that scholars and activists seeking to apply a CRT framework or conduct a CRT analysis in New Zealand should be mindful of the particular circumstances of the settler-colonising state imposed by the Crown. To assist with this mindfulness, we propose five guiding principles for CRT scholarship and praxis in New Zealand, which are all non-prescriptive and subject to critique and further development. To illustrate the usefulness of this framework, we undertake a critical reappraisal of the 1980 Tifaga v Department of Labour case. As we show, it is important to approach this case against the backdrop of the dawn raids and state-fuelled racism against Pacific peoples.
Efektivitas Penggunaan Difa SS Pada Soil-Bottom Ash Dan Soil Cement Dalam Meminimalkan Kerusakan Sub-Grade Jalan
Authors: Sumiati Sumiati , Mahmuda Mahmuda , Indra Siswa
Published: August 2022

Abstrak

 

Salah satu penyebab kerusakan jalan adalah seringnya struktur perkerasan jalan terendam air saat musim hujan. Tanah lempung berplastisitas tinggi mempunyai sifat fisik dan teknik yang kurang baik jika digunakan sebagai lapisan tanah dasar (sub grade), karena mempunyai sifat kembang susut yang tinggi dan nilai CBR yang rendah jika terendam air. Stabilisasi menggunakan chemical additive dan limbah pabrik merupakan salah satu cara untuk memperbaiki sifat fisik dan teknik tanah, di mana akan memberikan hasil yang memadai jika komposisi campuran yang digunakan sesuai dan tepat. Oleh sebab itu akan diteliti efektifitas penggunaan aditif Difa SS pada Soil-Bottom ash dan Soil-Cement dengan melakukan pengujian CBR laboratorium unsoaked dan soaked. Hasil penelitian didapatkan bahwa penambahan Difa SS tidak memberikan peningkatan nilai CBR soaked pada Soil-bottom ash. Nilai CBR soaked Soil-Cement menunjukkan peningkatan dan lebih besar dibandingkan nilai CBR unsoaked sehingga Difa SS lebih efektif digunakan sebagai chemical additive pada Soil-Cement dalam usaha meminimalkan kerusakan jalan.

Abstract

 

One of the causes of road damage is that the pavement structure is often submerged in water during the rainy season. High plasticity clays soils have poor physical and technical properties when used as a subgrade layer, because they have high sweeling and shrinkage properties and low CBR values when submerged in water. Stabilization using chemical additives and factory waste is one way to improve the physical and engineering properties of the soil, which will give adequate results if the composition of the mixture used is appropriate and appropriate. Therefore, the effectiveness of the use of Difa SS additive in Soil-Bottom ash and Soil-Cement will be investigated by conducting unsoaked and soaked laboratory CBR testing. The results showed that the addition of Difa SS did not increase the soaked CBR value in soil-bottom ash. Soil-Cement soaked CBR value shows an increase and is greater than the unsoaked CBR value so that Difa SS is more effectively used as a chemical additive in Soil-Cement in an effort to minimize road damage.

High school Career and Technical Education (CTE) has received increased attention from policymakers and researchers in recent years. This study fills a needed gap in the growing research base by examining heterogeneity within the wide range of programs falling under the broad moniker of CTE, highlighting the need for nuance in research and policy conversations that often consider CTE as monolithic. Using student-level course-taking records, unemployment insurance, and National Student Clearinghouse data, we examine outcomes including earnings, postsecondary education, and poverty avoidance. We find substantial differences for students in fields as diverse as health care, Information Technology (IT), and construction. We also highlight heterogeneity for student populations historically overrepresented in CTE, and we find large differences in outcomes for CTE students, particularly by gender.

Programs that improve teaching effectiveness represent a core strategy to improve student educational outcomes and close student achievement gaps. This article compiles empirical values of intraclass correlations for designing effective and efficient experimental studies evaluating the effects of these programs. The Early Childhood Longitudinal Study, Kindergarten Class of 1998–1999 (ECLS-K) data are used to estimate empirical design parameter values in the setting of students nested within teachers nested within schools. The results show that intraclass correlations at the school level are relatively stable, and those at the teacher level increase along with grade level. We illustrate the utility of the results by demonstrating how to leverage this information to design more efficient and effective experimental studies.
Lexical access in brain-damaged individuals: Evidence from anomic aphasia

Facilitation and inhibition are the two mechanisms of lexical activation. If one word in the lexical facilitates the activation of the other word, it is termed facilitation. On the other hand, if one word/lexical item impedes the activation of the other word in the lexicon, it is called inhibition. Many experimental tasks like naming and priming tasks can be used to tap these two mechanisms of lexical activation. The current study aimed to test these two patterns of lexical activation in persons with anomic aphasia. Ten persons with anomic aphasia and ten neurologically healthy individuals designated as group 1 and group 2 served as participants. The blocked naming task was administered to the participants. The semantically related blocks comprised pictures belonging to the same lexical category, while semantically unrelated blocks comprised pictures belonging to different lexical categories. For group 1, vocal reaction time and accuracy scores were better for unrelated blocks than related ones. For group 2, there was no evident difference between the vocal reaction time and accuracy scores for related and unrelated blocks. The difference between the vocal reaction time for semantically related and unrelated blocks was significant statistically only for group 1, indicating that the mechanism of lexical activation was different for the two groups. Better vocal reaction time for unrelated blocks indicated inhibition in persons with anomic aphasia.

Introduction: Coronavirus Disease 2019 (COVID-19), since its emergence, has spread rapidly as a pandemic causing massive loss of human life. This study aims to describe clinical severity of the disease in relation to age, mode of oxygen delivery and clinical outcome of patients admitted to a tertiary care center in Nepal.

Methods: This was a descriptive cross-sectional study of data records of 130 COVID-19 patients 18 years and above admitted in Nepal Armed Police Force Hospital from April 2021 to June 2021 with Severe Acute Respiratory syndrome SARS-CoV-2 Reverse Transcriptase Polymerase Chain Reaction positive status. Ethical approval was obtained from Nepal Health research Council. Data were collected using structured proforma and analyzed using SPSS version 23.  

Results: Patients with severe illness (52/130) constituted 40% of the bulk of COVID-19 patients, 48 of them requiring intensive care. Among them, 38.5% required non-invasive ventilation and 32.7% were intubated during treatment. Severity of illness was variable among different age groups but mortality was high among severely ill patients, 19/52 (36.5%) and with increasing age. The overall mortality was 19/130 (14%) over the study period, all of which were among severely ill patients.

Conclusions: Most of the clinically severe cases required Intensive Care Unit admission, the majority receiving oxygen therapy via non-invasive or invasive mechanical ventilation, with a high mortality rate. The number of severely ill COVID-19 patients was variable in different age groups. Mortality, however, was observed in severely ill patients only and proportionately increased in COVID-19 patients with advancing age.

Introduction: The epidemiological transition in Nepal has increased the burden of non-communicable diseases which have resulted in lower production and longer disability. Thus, the aim of the study was to estimate the prevalence of risk factors of Cardiovascular Diseases (CVDs) among government employees of Hetauda Sub-Metropolitan City. 

Methods: A cross-sectional descriptive study was conducted among 393 government employees of Hetauda sub metropolitan city. The ethical approval was taken from Nepal Health Research Council and informed consent was taken from each respondent before conducting the study. Cluster sampling was done where a modified WHO STEPS survey questionnaire was self-administered among the respondents. The collected data was entered and analyzed using SPSS Version 20.

Results: Out of 393 respondents, the prevalence of current smokers was 16.3%, more than two-third (72.9%) consumed alcohol in the past 30 days, and a vast majority did not consume both fruit and vegetables in adequate amounts. Similarly, more than two-third respondents (67.2%) never practiced any physical activity. The self-reported diabetes was found among 11.7% of participants whereas 19.4% had hypertension. Majority (70%) had normal BMI however; both male and female were found to be at risk for waist/hip ratio.   

Conclusions: Almost every government employee was found to have one or more established risk factors of CVDs. This emphasizes the importance of taking quick action to avert the epidemic of cardiovascular disease.
