Published: May 2022

Prophylactic vaccination against infectious diseases is one of the most successful public health measures of our lifetime. More recently, therapeutic vaccination against established diseases such as cancer has proven to be more challenging. In the host, cancer cells evade immunologic regulation by multiple means, including altering the antigens expressed on their cell surface or recruiting inflammatory cells that repress immune surveillance. Nevertheless, recent clinical data suggest that two classes of antigens show efficacy for the development of anticancer vaccines: tumor-associated antigens and neoantigens. In addition, many different vaccines derived from antigens based on cellular, peptide/protein, and genomic components are in development to establish their efficacy in cancer therapy. Some vaccines have shown promising results, which may lead to favorable outcomes when combined with standard therapeutic approaches. This review provides an overview of the innate and adaptive immune systems, their interactions with cancer cells, and the development of various different vaccines for use in anticancer therapeutics.

The new Omicron variant of SARS-CoV-2, first identified in November 2021, is rapidly spreading all around the world. Omicron has become the dominant variant of SARS-CoV-2. There are many ongoing studies evaluating the effectiveness of existing vaccines. Studies on the neutralizing activity of vaccinated sera against the Omicron variant are currently being carried out in many laboratories. In this study, we have shown the neutralizing activity of sera against the SARS-CoV-2 Omicron variant compared to the reference Wuhan D614G variant in individuals vaccinated with two doses of Sputnik V up to 6 months after vaccination and in individuals who experienced SARS-CoV-2 infection either before or after vaccination. As a control to our study we also measured neutralizing antibody titers in individuals vaccinated with two doses of BNT162b2. The decrease in NtAb titers to the Omicron variant was 8.1-fold for the group of Sputnik V-vaccinated individuals. When the samples were stratified for the time period after vaccination, a 7.6-fold or 8.8-fold decrease in NtAb titers was noticed after up to 3 and 3-to-6 months after vaccination. We observed a 6.7- and 5-fold decrease in Sputnik V-vaccinated individuals experiencing asymptomatic or symptomatic infection, respectively. These results highlight the observation that the decrease in NtAb to the SARS-CoV-2 Omicron variant compared to the Wuhan variant occurs for different COVID-19 vaccines in use, with some showing no neutralization at all, confirming the necessity of a third booster vaccination.

Published: May 2022

Objective: to identify factors associated with COVID19 vaccine hesitancy, including sources of information among residents of Maine. Methods: 148 study participants, recruited through community partners and primary care offices in Maine, completed an anonymous 15 item online survey. Recruitment and data collection occurred from May to September, 2021. Hesitancy was determined through a single question, “Will you get one of the COVID vaccines when it is offered to you?” Results: vaccine hesitant respondents were younger than not hesitant respondents (p = 0.01). Hesitant individuals were significantly more likely to report concerns regarding the speed of COVID-19 vaccine production, vaccine efficacy, and potential vaccine side effects (p < 0.05 for each). Hesitant individuals were also significantly more likely to have discussed vaccination with their primary physician (p = 0.04). Conclusions: overall, hesitant individuals are more likely to be younger and had less trust in information from government sources, but they sought input from primary care. They were also more concerned about efficacy, side effects, and the rapid development of COVID-19 vaccines. Primary care physicians are in key positions to address these concerns due to contact with individuals who need accurate information.

Published: May 2022

Dog trials and competitions involve various sport disciplines, e.g., obedience, agility, working dog trials and rally obedience. Dog handlers navigate their dogs through physically and mentally demanding tasks. The purpose of this study was to gain a better understanding of barriers and facilitators to canine health promotion and injury prevention described by dog handlers. Methods: Qualitative inductive content analysis was applied to systematically organize and interpret narrative data from 654 respondents’ answers to open-ended questions in an anonymous online inquiry. Results: Two categories, with seven sub-categories, emerged from the analysis: (1) Challenges in applying the regulations in dog trials and competitions, and (2) Implementation of animal welfare and canine well-being approaches. Respondents described the challenges in applying regulations in dog trials and competitions and lack of scientific research as barriers to their intent to prevent injuries in their dogs. Implementation of animal welfare and canine well-being approaches were described as facilitators. Conclusion: The findings imply that the stakeholders continuously need to work on bridging possible gaps between the canine welfare criteria and the scientific and empirical knowledge in canine sports and performance medicine.

Authors: Ashurko I. P. , Tarasenko S. V. , Esayan A. V. , Galyas A. I. , Li A. V.
Published: May 2022

Relevance. Implant-supported prostheses are currently one of the most popular rehabilitation methods in partially or fully edentulous patients. Peri-implant soft tissue thickness is one of the principal determinants to achieve an aesthetic result and prevent the development of mucositis and peri-implantitis.

Material and methods. The study included 30 partially edentulous patients with a lack of soft tissue thickness in the planned surgery site. 15 patients underwent augmentation using a collagen matrix (group 1) and 15 patients – with a free connective tissue graft (group 2). The primary endpoint was the assessment of soft tissue thickness gain three months after the surgery. The secondary endpoints were the thickness assessment of keratinized attached gingiva (three months after the surgery), swelling and pain severity (on the 1st, 3rd, 5th, 7th day, 1 and 3 months after the surgery) and quality of life evaluation (OHIP-14) (before the surgery, seven days and three months after the surgery).

Results. The soft tissues thickness gain was 1.181 ± 0.11 mm in group 1, 1.55 ± 0.11 mm – in group 2. The surgery took 8.4 minutes less (from 3.737 to 13.06) in group 1 than in group 2. The swelling assessment on the next day after surgery showed that the mean value was 2.73 ± 0.3 in group 1, 1.87 ± 0.74 – in group 2 (р = 0.0139). There were no statistically significant differences in the change in the width of the keratinized attached gingiva, pain syndrome and changes in patients' quality of life (p > 0.05)

Conclusion. Collagen matrix, like a free connective tissue graft, is an effective way to increase the soft tissue thickness around dental implants.

Published: May 2022

Relevance. Microcirculation disorder is one of the leading mechanisms in the pathogenesis of inﬂammatory and degenerative periodontal diseases. Modern medicine assesses the blood ﬂow by the Doppler ultrasound, which has some essential advantages for a researcher. However, the possibilities of interpreting Doppler ultrasound data remain scarcely enlightened in the scientiﬁc literature.

Materials and methods. Forty patients of both sexes, aged 18–25 years, with clinically intact periodontium, underwent a Doppler ultrasound test to investigate microcirculation in the area of tooth 1.6 at the levels of free gingiva, attached gingiva and mucobuccal fold, to study the integral characteristics of a Doppler ultrasound of tissue blood ﬂow. The obtained data were statistically analyzed using the method of principal component analysis.

Results. The principal component analysis demonstrated that Vam and Qam were the parameters closest to the integral blood ﬂow velocity, and the attached gingiva was the optimal point for transducer position.

Conclusion. The principal component analysis allowed obtaining an integral parameter of blood ﬂow velocity (PC 1) and its features in various areas of the periodontium on tooth 1.6. Further studies are necessary due to the possible variability of periodontal microcirculation on other maxillary and mandibular teeth.

The creation of this painting originated from the author's experience when discussing endless issues of women. Social issues regarding women are always updated in various issues ranging from discrimination, crime and injustice against women. In fact, this feminist issue has existed since time immemorial with the story of Dewi Shinta, who has always carried feminine values. The aim is to create paintings that have a feminist value concept in Dewi Shinta and create paintings through the process of selecting sketches, materials, manufacturing techniques, exploration, and presentation that have the meaning of feminist firmness values. The method used in this thesis is the method of making a thesis. In the realm of this creation process consists of several stages, namely the formation stage (Forming). Coloring (Colloring), Finishing (Finishing). The creators hope that this work can be used as inspiration to create works of art that are always updated. Conceptually, the creation of painting works wants to build a national cultural character that is increasingly fading through feminist values.

Authors: Meneghetti Fronza Diagna , Soto Machado Cristiane
Published: May 2022

Introdução. Lesões medulares (LM) são agressões à medula espinhal que comprometem funções motoras e sensoriais. O sucesso terapêutico da reabilitação na LM depende da adesão ao tratamento, que requer baixa impulsividade. A impulsividade pode ser medida através de um procedimento experimental denominado desconto pelo atraso (DA). Objetivo. Utilizar o DA para avaliar a impulsividade de pacientes com LM internados para reabilitação ao longo da hospitalização e correlacioná-la com variáveis sociodemográficas. Método. Trata-se de pesquisa quantitativa, indutivista, longitudinal, com delineamento misto. Os(as) participantes foram 9 pacientes do Centro Estadual de Reabilitação e Readaptação Dr Henrique Santillo. Os critérios de inclusão foram apresentar LM, ter idade de 18 a 59 anos, e estar internado para reabilitação; o critério de exclusão foi apresentar lesão encefálica. O procedimento de DA foi aplicado quatro vezes com cada participante durante a internação, com intervalo médio de uma semana entre aplicações. Resultados. 88,9% da amostra eram homens, de idade média de 34,11 anos. Foi observado aumento da impulsividade durante a internação, mais expressivo entre a segunda e terceira semanas, bem como maior impulsividade em pessoas de baixa escolaridade. Conclusão. Há aumento da impulsividade em pessoas com LM durante a internação para reabilitação, possivelmente relacionado a maiores níveis de estresse ocasionados pela hospitalização.

Background

Obesity is increasingly common in kidney transplant candidates and may limit access to transplantation. Obesity and diabetes are associated with a high risk for post-transplant complications. The best approach to weight loss to facilitate active transplant listing is unknown, but bariatric surgery is rarely considered due to patient- and physician-related apprehension, among other factors.

Methods

We aimed to determine the magnitude of weight loss, listing, and transplant rates in 28 candidates with a mean BMI of 44.4±4.6 kg/m2 and diabetes treated conservatively for 1 year post weight-loss consultations (group 1). Additionally, we evaluated 15 patients (group 2) who met the inclusion criteria but received bariatric intervention within the same time frame. All patients completed a multidisciplinary weight management consultation with at least 1 year of follow-up.

Results

In the conservatively managed group (group 1), the mean weight at the time of initial consultation was 126.5±18.5 kg, and the mean BMI was 44.4±4.6 kg/m2. At 1 year post weight-loss consultation, the mean weight decreased by 4.4±8.2 kg to 122.9±17 kg, and the mean BMI was 43±4.8 kg/m2, with a total mean body weight decrease of 3% (P=0.01). Eighteen patients (64%) did not progress to become candidates for active listing/transplantation during the follow-up time of 4±2.9 years, with 15 (54%) subsequently developing renal failure/diabetes-related comorbidities prohibitive for transplantation. In contrast, mean total body weight decreased by 19% at 6 months post bariatric surgery, and the mean BMI was 34.2±4 and 32.5±3.7 kg/m2 at 6 and 12 months, respectively. Bariatric surgery was strongly associated with subsequent kidney transplantation (HR=8.39 [95% CI 1.71 to 41.19]; P=0.009).

Conclusions

A conservative weight-loss approach involving multidisciplinary consultation was ineffective in most kidney transplant candidates with diabetes, suggesting that a more proactive approach is needed.

In this paper, Binary Particle Swarm Optimization Algorithm has been employed to enhance the yearly profit of a wind farm in Kayathar town of India with a novel transfer function. The optimization trial outcomes validate the superiority of the proposed transfer function when compared with similar ‘S’-type transfer functions.
The Inverted Yield Curve, Austrian Business Cycle Theory, and the True Money Supply
Authors: Griggs Ryan , Murphy Robert
Published: May 2022

Ever since Campbell Harvey’s (1986) doctoral dissertation, academic economists have studied the ability of an inverted yield curve to “predict” an impending recession with impressive accuracy given suitable specifications. Many economists (including Campbell) explain the correlation by neoclassical “consumption smoothing,” while others attribute the connection to monetary policy’s ability to affect the business cycle. We agree with Cwik (2004 and 2005) that the Misesian circulation credit theory of the trade cycle, relying on both monetary and “real” (capital structural) elements, is superior to both flavors of mainstream explanation. In this paper, our contribution is to show that the growth rate of the Rothbard-Salerno measure of the “true money supply” tracks movements in Treasury bond spreads remarkably well. This provides additional support for our claim that the Austrian theory of the business cycle explains the “predictive power” of the yield curve better than the mainstream approach.

Published: May 2022

This review article contains current scientific literature data about the impact of infectious diseases and tuberculosis particulary on the formation of systemic insulin resistance in patients. A number of immune reactions have been reported in the host body in response to tuberculosis infection, which may lead to the development of hyperglycemia in TB patients. Some authors believe that such disorders are transient and disappear after a course of specific treatment, others - are inclined to believe that tuberculosis can cause diabetes in people who have not previously suffered from it, and long-term impairment of carbohydrate metabolism that occurs under the time of active tuberculosis process forms a vicious circle in which insufficiently controlled blood glucose levels can lead to aggravated TB and provoke complications in the form of cardiovascular disorders. Also, we found data on the transformation of latent disorders of carbohydrate metabolism in manifest diabetes mellitus during 1-4 years of follow-up of patients with tuberculosis.

ANALYSIS OF RATING SYSTEMS FOR EVALUATION OF COMPETITIVENESS OF HIGHER EDUCATION INSTITUTIONS
Authors: Kryvoruchko Vladyslav
Published: May 2022

The rating systems of higher education institutions (hereinafter – HEI) has been researched in the article. It has been determined that today the rankings of universities are the most legitimate and unified methods of analysis of the competitiveness of free economic zones in the market of educational services. The key role of HEI as producers of new knowledge in the market in the conditions of intellectualization of economic processes has been substantiated. It has been described that in countries with market economies, competition in education is based on the same principles as in business. The quality of education and knowledge is a key competitive advantage of HEI in the market.
Methods of comparison, abstraction, analysis, synthesis and graphical methods have been used in the research. A comparative analysis of the structure of the evaluation criteria of each of the ratings was conducted and it was determined which indicators have the most significant impact on the rating result. The analysis of knowledge quality indicators within each of the rating systems as exceptional and influential indicators in the knowledge economy have been conducted separately.
The key problems of university rating have been identified: the asymmetry of the importance of the impact of different criteria in the direction of resource provision and capitalization of free economic resources; incomplete assessment of the quality of knowledge management (work with the knowledge repository, internal training, training of research and teaching staff, mobility of teachers and students); lack of indicators to assess the brand and image of the HEI in the market; the degree of use of digital technologies in education and indicators of the management system analysis as an organization (assessment of the level of bureaucracy and quality of internal business processes).
As a result of the research, the author's approach to the assessment of the competitiveness of HEI has been proposed, which involves the categorization of educational institutions according to certain criteria and the development of indicators of free economic analysis for each category. Also, it has been proposed to expand the range of criteria for assessing the competitiveness of the Ukrainian HEI, taking into account the requirements of today. The results of the study have been aimed at improving the quality assessment system of education and analysis of the competitiveness of domestic higher education institutions, as well as improving the tools for assessing the quality of knowledge management in the implementation of these systems in educational institutions.

This paper aims to develop bacterial cellulose (BC) based biocomposites reinforced by bamboo microfibrillated cellulose (MFC) by the impregnation method, using epoxidized waste cooking oil (EWCO) as plasticizer, and to investigate the effect of EWCO on the properties of the biocomposites. The obtained materials were characterized by tensile testing, thermogravimetric analysis (TGA), X-ray diffraction (XRD), differential scanning calorimetry (DSC), scanning electron microscopy (SEM), and Fourier-transform infrared spectroscopy (FTIR) analyses. The optimum composition of the biocomposites was achieved with 1% w/w bamboo MFC as reinforcement agent and 0.5% v/v EWCO as plasticizer. Triple replications of the tensile test revealed slight differences between the unplasticized BC-based biocomposites and the plasticized BC-based biocomposites. The tests revealed that MFC impregnation in the BC-based biocomposite can enhance tensile strength. Thus, while the tensile strength of the BC was 9.6 MPa, it reached 40 MPa for the unplasticized BC-based biocomposites reinforced with bamboo MFC, and 37.8 MPa for the plasticized BC-based biocomposites. Reinforcing with bamboo MFC and plasticizing with EWCO can increase the degradation temperature of the BC-based biocomposite, while plasticizing can affect the crystalline structure of the material. Both BC-based biocomposites reached higher glass transition temperature than that of the initial BC.

Opuntia ficus indica cladodes (OFIC) were used as an adsorbent for the removal of anionic Bemacid Red (RB) dye from an aqueous solution. The study was performed in a batch reactor under different experimental conditions. The adsorption process was very fast during the first 60 min of phases’ contact at 25 °C, the adsorbent being characterized by an adsorption capacity of 16.721 mg/g at pH 2. The experimental data fitted very well with the pseudo-second-order kinetic model (R2 = 0.994), and the Langmuir, Freundlich, Temkin and Dubinin-Radushkevich adsorption models were applied to describe the adsorption equilibrium isotherms. The thermodynamic parameters: enthalpy (-20.739 kJ/mol), entropy (-0.226 kJ/K.mol) and the Gibbs free energy (-14 to -13.557 kJ/mol) were determined over the selected temperature range (25 to 45 °C). The adsorption using the studied system (OFI cladodes/RB) proved to be an exothermic and spontaneous process.
Multi-band perfect absorber based on graphene monolayer coupled to photonic nanostructure

Published: May 2022

An active plasmonic device is designed to support multiple perfect absorption peaks using the highly confined graphene surface plasmons excited by silicon-based diffractive gratings. The physical origination corresponding to different absorption peaks is analyzed and the principle of impedance matching is used to explain perfect absorption. We show that the absorption spectrum is effectively controllable over a wide wavelength range by changing the Fermi levels, relaxation time of the graphene and geometric parameters of the device. This study could provide some possibilities facilitating the design of next-generation optical and photoelectronic structures by combining graphene and dielectric grating.

The purpose of this paper on “Al Shabaab and its Violent Extremism in Kenya” aimed at exploring the dynamics of al Shabaab in Somalia as it affected Kenya. This descriptive research adopted judgmental sampling technique and relied mostly on secondary source (books, journal articles, monographs, internet materials etc) of data collection which were sourced in Nigerian libraries, subjected to content validity before analyzing qualitatively. Results of the findings revealed that the spillover of al Shabaab’s violent extremism to Kenya was caused by porous borders as well as local forces such as historic marginalization, propaganda technique and the presence of al Hijrah sect in Kenya. Al Shabaab has impacted negatively on Kenya’s security, diplomacy, economy as well as humanitarian services. Kenya has responded through the creation of Operation Linda Nchi and Operation Usalama Watch while United States, Africa Union Mission in Somalia, United Nations and European Union also assisted in fighting the dreaded sect according to findings. The contribution of these findings to the explanation of Rosenau’s linkage theory is excellent thereby deepening the understanding of its basic assumptions. Regrettably, Al Shabaab is still a potential threat to Kenya and the entire Horn of Africa, therefore, the paper recommends inclusive dialogue, national integration and constructive engagement as panacea for al Shabaab violent extremism.

Biliary lithiasis is a very frequent and benign pathology but can be the cause of rich and varied symptomatology as well as serious complications. Our study aims to estimate the prevalence and some risk factors of biliary lithiasis and especially to look for the correlation between this pathology and anthropometric measurements. Therefore, we conducted a campaign that included 1358 citizens to perform ultrasound screening for biliary lithiasis, hepatic steatosis, and hydatid cyst. In our study, the prevalence of biliary lithiasis was 19.2%. The average age was 47.7 years with a predominance of women, i.e. a percentage of 76.6%. The risk factors significantly associated with gallstones were abdominal obesity, male sex, and age below 40 years were protective factors, however, neither diabetes nor a history of hypercholesterolemia was associated with the risk of gallstones.

Wolff-Parkinson-White (WPW) syndrome is a relatively rare cardiac rhythm disorder entity encountered during pregnancy. However, its exacerbation under this physiological condition could be responsible, in certain cases, for life-threatening arrhythmias compromising both maternal and foetal prognosis. We report the observations of 03 pregnant women, without past medical history, presenting to the emergency room for palpitations related to a Wolff-Parkinson-White syndrome, complicated in one case with foetal death. The substantial severity of the WPW syndrome during pregnancy requires a prompt and adequate management strategy, based on a multidisciplinary cooperation between obstetricians, cardiologists and neonatologists.
Wellens Syndrome: A Case like No Other!

Published: May 2022

Introduction: Wellens syndrome or anterior interventricular artery (AIV) disease is an electrocardiographic abnormality defined by the presence, apart from painful episodes, of biphasic T waves in the anterior leads (type 1), or deeply inverted T waves (type 2) in association with critical stenosis of the proximal AIV. It warrants aggressive management given the rather high incidence of death and re-infarction. Objectif: To report an atypical form of this syndrome through this observation and to provide an update on this rare entity through a literature review. Case report: A 48-year-old patient, chronic smoker with 40 BPs still active, admitted following an episode of infarct chest pain. At admission, the patient was asymptomatic. The clinical examination was unremarkable. The ECG showed biphasic T waves, negative in its terminal part in V2-V3-V4, without planed R waves, nor Q waves of necrosis or significant ST abnormality evoking a WELLENS type 1 syndrome. Ultrasensitive troponin was measured at 260 ng/L. The evolution was marked by the appearance of a fleeting negativation of T waves, without chest pain. Chest echocardiography showed a non-dilated left ventricle with preserved systolic function and no detectable segmental or global kinetic disorders, associated with concentric left ventricular hypertrophy. The coronary angiography performed in emergency shows tritroncular lesions, a very tight stenosis of the middle interventricular and the first diagonal, a tight stenosis of the middle circumflex and the middle right coronary, revealing a coronary artery bypass graft. Discussion and conclusion: Wellens syndrome is characterized by T-wave abnormalities that often fluctuate (from type 1 to type 2 or vice versa) during pain-free intervals, reflecting spontaneous reperfusion and the unstable nature of the coronary lesion found, which is represented mainly by involvement of the proximal AVI. Involvement of the middle IVA associated with other lesions is rarely observed. It is associated with a greater risk of anterior infarction or sudden death if not recognized and treated rapidly, so it seems essential to recognize the electrocardiographic criteria of this syndrome in order to propose coronary angiography for early revascularization.
