A 40-year-old woman was admitted to hospital with fever and cough during the pandemic of COVID-19. Past medical was notable for advanced chronic kidney disease. On admission, nucleic acid testing of a nasopharyngeal swab was positive for SARS-CoV-2. After 11 days she was considered cure with two negative tests in a row. Eight weeks later, she was going to receive a kidney transplant from a deceased donor, but she was tested again for SARS-CoV-2 and the result came out positive. After that, surgery was cancelled. In our opinion, this test should not have been performed. Through this case we overview the knowledge about infectivity, reinfection and reactivation of SARS-CoV-2. We believe who has been considered cured in the last three months should undertake immunosuppression treatment in case of transplant or cancer treatment. In these cases, benefits outweigh the eventual risks for most patients.

INTRODUCTION: The impact of the COVID-19 pandemic on orthopedic trauma surgery is not well characterized in the literature. We provided an evaluation of such impact in a tertiary hospital in Portugal.MATERIAL AND METHODS: Retrospective analysis of the patients admitted for surgical treatment due to acute orthopedic trauma from March to December of 2019 and March to December of 2020.RESULTS: A total of 794 patients in 2019 and 728 in 2020 were included. Although the mean time to surgery was shorter the hospital stay was longer in 2020. Infected patients had a longer hospital stay and longer time until surgery compared to non-infected. There was no significant difference between the mortality and need for treatment in the intensive care unit (ICU) in both years. There was a significant increase in the number of polytrauma patients treated in our institution in 2020 compared to 2019.CONCLUSION: Orthopedic trauma surgery was globally influenced by the pandemic. Safe and effective measures should be adopted in the treatment of trauma patients, to reduce the clinical and economic impact.
An exact constant on the estimation of the approximation of classes of periodic functions of two variables by Ceśaro means
Authors: Rovenska O. G. 
Published: March 2022

In the present work, we study problem related to the approximation of continuous $2\pi$-periodic functions by linear means of their Fourier series. The simplest example of a linear approximation of periodic function is the approximation of this function by partial sums of the Fourier series. However, as well known, the sequence of partial Fourier sums is not uniformly convergent over the class of continuous $2\pi$-periodic functions. Therefore, a significant number of papers is devoted to the research of the approximative properties of different approximation methods, which are generated by some transformations of the partial sums of the Fourier series. The methods allow us to construct sequence of trigonometrical polynomials that would be uniformly convergent for all functions $f \in C$. Particularly, Ceśaro means and Fejer sums have been widely studied in past decades.One of the important problems in this field is the study of the exact constant in an inequality for upper bounds of linear means deviations of the Fourier sums on fixed classes of periodic functions. Methods of investigation of integral representations for trigonometric polynomial deviations are generated by linear methods of summation of the Fourier series. They were developed in papers of Nikolsky, Stechkin, Nagy and others.
The paper presents known results related to the approximation of classes of continuous functions by linear means of the Fourier sums and new facts obtained for some particular cases.In the paper, it is studied the approximation by the Ceśaro means of Fourier sums in Lipschitz class. In certain cases, the exact inequalities are found for upper bounds of deviations in the uniform metric of the second order rectangular Ceśaro means on the Lipschitz class of periodic functions in two variables.
Teachers, Parents and Educationalists' Perceptions towards Introducing English at Early Stage in Libyan Schools: An Explanatory Study
Authors: Ramadan Mohammed 
Published: March 2022

This study has sought to explore the teachers, parents, and educationalists' understudy perceptions towards the introduction of English language at an early stage in Libyan schools and their possible reasons for supporting/opposing this idea. For this purpose the study employed a quantitative research design with a close- ended questionnaire in order to obtain the essential data for the study. Data was then analyzed manually and the main findings indicated that the study's participants generally agree with the idea of introducing English at an early stage because they believe that teaching English at such stage can a) make pupils very proficient in English, b) develop pupils' cognitive abilities, c) lead pupils to a better academic performance in their education; d) increase pupils motivation for learning in the future. On the other hand, those who opposed introducing English did so because they thought it may a) negatively influence the pupils’ acquisition of their mother language, Arabic; b) increase the burden on pupils; c) invade pupils’ native culture.

Published: March 2022

A desolvation method was used for the synthesis of β-galactosidase (β-GAL) and glucose oxidase (GOD) nanoparticles (NPs) using ethanol. The enzyme nanoparticles (ENPs) were characterized by transmission electron microscopy (TEM) and Fourier transform Infra-red spectroscopy (FTIR) and were co-immobilized covalently onto surface of polycrystalline Au electrode. An improved amperometric lactose biosensor was constructed using ENPs (β-GALNPs/GODNPs) modified Au electrode as working electrode, Ag/AgCl as reference electrode and Pt wire as auxiliary electrode connected through potentiostat. Cyclic voltammetry (CV) and scanning electron microscope (SEM) were used for the study of working electrode before and after immobilization of ENPs. The biosensor showed maximum current at 0.25V within 5s, at pH 6.5 and 25oC. The limit of detection (LOD) was i.e. 1mg/ml and working range was 1-10 mg/mL. The analytical recovery of added lactose (5 and 10 mg/mL) was 94.73±0.5% and 96.4±0.9%, respectively. Coefficient of variation (CV) within and between batch were <3.0 and <4.0 respectively. The biosensor exhibited a good correlation (R2=0.91) between lactose level in milk as measured by standard (enzymatic colorimetric) method and present biosensor. The biosensor was employed for quantification of lactose in milk from human, cow, buffalo and goat. The working electrode lost 50% of its initial activity within 3 months, after its 120 uses, while being stored dry at 4ºC.

Published: March 2022

A field experiment was carried out with an objective to study the effect of nitrogen levels in the growth and yield performance of French bean (Phaseolus vulgaris L.) (PDR 14 or Uday) at Institute of Agriculture and Animal Science (IAAS), Rampur, Chitwan, Nepal from October 2008 to March 2009. The experiment of nitrogen levels was carried out with five treatments of 0, 40, 80, 120 and 160 kg/ha with three dates of sowing in three replications in split plot design. The soil of the experimental plots was sandy loam with acidic (pH 6.33) in nature. The effect of nitrogen levels on growth pattern and grain yield was found significant. Significantly higher grain yield was obtained with 120 kg N/ha (2.57 t/ha) as compared to control (1.39 t/ha), 40 (1.84 t/ha), 80 (2.04 t/ha) and 160 (2.01 t/ha) kg N/ha, respectively. The yield increased significantly with nitrogen up to 120 kg/ha and then declined at 160 kg/ha. So, in order to achieve higher productivity of French bean, 120 kg N/ha can be considered as an optimum level of nitrogen application in the humid sub-tropical condition of inner Terai, Chitwan of Nepal.

Authors: Kovalenko O.Y. , Prityko N.G. 
Published: March 2022

Relevance: The problem of treatment of cerebrovascular diseases is one of the leading in modern medicine. The combination of this nosology in patients with emotional and volitional disorders acquires a special shade. Features of neurochemical transmission of impulses in different hemispheres of the brain provide greater opportunities for improving the treatment of patients with chronic cerebral venous dysfunction syndrome (SCVD).
Objective: To study the features of hemispheric lateralization of the brain in patients with SCVD and indicators of anxiety on the Spielberger-Khanin scale and depression on the Beck scale. Materials and methods: 153 patients tested on the scale of reactive (RT) and personal (LT) anxiety Spielberger-YL Khanin and Beck depression. 125 people with signs of SCCVD and various levels of BP. Mean age of patients: 53.60 ± 10.27 years, 115 women, 38 men. All underwent clinical and neurological examination, testing to determine hemispheric dominance on the scale of NP Rebrova and MP Chernysheva. Statistics were calculated using the Medstat program. The comparison was performed according to the criterion of W. Kruskal-A. Wallis, the criterion of J. Dunn and the chi-square. Results: It was found that the presence of SCCVD did not depend on hemispheric dominance. In patients with SCVD with left hemisphere lateralization, there was a statistically significant increase in personal anxiety on the Spielberger-Khanin scale (p<0.001). The patients with SCVD and right-hemispheric lateralization had a statistically significant increase in depression on the Beck scale (p <0.001). Patients of the control group did not show a statistically significant relationship between the types of hemispheric dominance and indicators of personal anxiety and depression.
MODERN APPROACHES TO TREATMENT OF ACUTE LEFT VENTRICULAR INSUFFICIENCY IN PATIENTS AFTER AORTO-CORONARY SCANNING SURGERY IN CONDITIONS IN CONDITIONS
Authors: Cherniy V.I. , Kurylenko Ya.V. 
Published: March 2022

Introduction. Coronary heart disease is the leading cause of death and disability worldwide. For patients with three or more coronary arteries lesion, revascularization with coronary artery bypass grafting (CABG) is the best treatment. 10% of all patients require re-hospitalization within 30 days of discharge, the most common cause being heart failure. The most formidable complication after CABG surgery with cardiopulmonary bypass (CPB) is the development of acute left ventricular failure (ALVF).
The aim. To analyze the problems of correction of ALVF after CABG with CPB from the sources of modern literature to optimize the management of the perioperative period in this group of patients.
Materials and methods. Bibliosemantic, comparative and method of system analysis. The proposed recommendations are based on the analysis of modern literature, the results of randomized trials and meta-analyzes to study the problem of correction of ALVF after CABG with CPB.
Results. Inotropic support for ALVF after CABG with CPB is prescribed based on the presence of a number of factors. Adrenomimetics, phosphodiesterase inhibitors and calcium sensitizers are prescribed for the correction of ALVF. In addition to inotropics, the myocardium has a positive effect on metabolic drugs: levocarnitine and arginine. When medical treatments are exhausted, resort to the use of hardware treatments: intra-aortic balloon pump, left ventricle assist device, Impella, extracorporeal membrane oxygenation.
Conclusions. Given the variety of classes of drugs and their active components, dobutamine remains the most affordable, safe and effective drug for the treatment of ALVF after CABG with CPB. The combination of L-carnitine and arginine has a number of effects that have a stabilizing effect on the operated myocardium. For the treatment of ALVF after CABG with CPB, in order to achieve a stabilizing effect on the myocardium, it is advisable to investigate the combined use of dobutamine with L-carnitine and arginine to combine the positive effects of drugs.

The research results of influence of the continuous application of the various systems of primary tillage and fertilization on the productivity of mustard white (Sinapis alba) were presented. It was found that the highest yield of white mustard seeds (1.89 t/ha) on the background of N60P60K60 fertilizers was formed under moldboard plowing. Against the background of organic and mineral fertilization (predecessor residues and application of N30P30K30), the highest seed yield (1.90 t/ha) was provided by the moldboard plowing. The use of traditional fertilizer of N60P60K60 for white mustard compared to the combination of crop residues and N30P30K30 fertilizers was economically unprofitable. It is established that against the background of organic and mineral fertilization compared to mineral, the thinning of white mustard crops under minimal nonmoldboard cultivation reached almost 40–50 %. In general, the density of mustard plants on the background of organic and mineral fertilization was 1.5–1.55 mln plants/ha, and on the mineral – 1.65–1.7 mln plants/ha, i.e. on average it was lower by 10 %. Analysis of the economic efficiency of growing white mustard showed that the subsurface tillage on the background of organic and mineral fertilization (predecessor residues and the application of N30P30K30) can be considered as the most promising and adapted to current weather conditions. The profitability of white mustard seed production was 263 %; almost such indicators of profitability were noted under chisel tillage – 259 %. It was found that the introduction of any subsurface tillage for white mustard on the background of organic and mineral fertilization is more profitable.

Condition Optimization for The Analysis of Risperidone and 9-0H-Risperidone by High-Performance Liquid Chromatography
Authors: Yusuf Luki Yogaswara , Hasanah Aliya Nur , Barliana Melisa Intan 
Published: March 2022

Risperidone (RIS) is one of the most widely used atypical antipsychotics for treating schizophrenia in hospitals. RIS is metabolized by the liver and produces the primary active metabolite 9-OH-Risperidone (9-OHR). In the process of RIS metabolism, it is suspected that there are gene polymorphisms that cause variations in patient responses. Analysis of RIS and 9-OHR levels in the patient's blood can help to explain the various responses. High-Performance Liquid Chromatography (HPLC) is the most popular method to analyze RIS and 9-OHR, but many deficiencies were found in the chromatograms in the previous study. This research aims to obtain optimal conditions of the analysis prior to method validation. Condition optimization by optimizing the wavelength, composition of the mobile phase, pH, flow rate, and particle size of the stationary phase. The results showed that the wavelength was 279 nm, the mobile phase was 0.05 M KH2PO4 pH 3.7: acetonitrile (94:6, v/v) plus 0.3% triethylamine, and the flow rate was 1.2 ml/min in the stationary phase (LiChroCART® RP 18; 250x4 mm; 10 µm) being the optimal condition. This method is suggested to continue method validation for analyzing RIS and 9-OHR in the serum or plasma.
