Neuroprotective Role of Nutritional Supplementation in Athletes
Authors: Chawla Viney , Mishra Supriya , Singh Vikram Jeet , Chawla Pooja A
Published: December 2021

Background:

Neurodegenerative disorders belong to different classes of progressive/chronic conditions that affect the peripheral/central nervous system. It has been shown through studies that athletes who play sports involving repeated head trauma and sub-concussive impacts are more likely to experience neurological impairments and neurodegenerative disorders in the long run.

Aims:

The aim of the current narrative review article is to provide a summary of various nutraceuticals that offer promise in the prevention or management of sports-related injuries, especially concussions and mild traumatic brain injuries.

Methods:

This article reviews the various potential nutraceutical agents and their possible mechanisms in providing a beneficial effect in the injury recovery process. A thorough survey of the literature was carried out in the relevant databases to identify studies published in recent years. In the present article, we have also highlighted the major neurological disorders along with the associated nutraceutical(s) therapy in the management of disorders.

Results:

The exact pathological mechanism behind neurodegenerative conditions is complex as well as idiopathic. However, mitochondrial dysfunction, oxidative stress as well as intracellular calcium overload are some common reasons responsible for the progression of these neurodegenerative disorders. Owing to the multifaceted effects of nutraceuticals (complementary medicine), these supplements have gained importance as neuroprotective. These diet-based approaches inhibit different pathways in a physiological manner without eliciting adverse effects. Food habits and lifestyle of an individual also affect neurodegeneration.

Conclusion:

Studies have shown nutraceuticals (such as resveratrol, omega-3-fatty acids) to be efficacious in terms of their neuroprotection against several neurodegenerative disorders and to be used as supplements in the management of traumatic brain injuries. Protection prior to injuries is needed since concussions or sub-concussive impacts may trigger several pathophysiological responses or cascades that can lead to long-term complications associated with CNS. Thus, the use of nutraceuticals as prophylactic treatment for neurological interventions has been proposed.
TRANSFORMATION OF RELIGIOUS VALUES: DIMENSIONS OF RELIGIOUS STUDIES AND SOCIOLOGY
Authors: Tytarenko Vita , Fylypovych Liudmyla
Published: December 2021

The article is devoted to rethinking methodological approaches in understanding of religion as a value by religious studies. A critical attitude to the previous experience of interpreting a religious phenomenon allows us to perceive religion as a value equal with other types of human self-awareness. This is prompted by the very status of religion in the modern world, which is changing under the influence of globalization and secularization. One of the trends of these processes is the departure from the restrictions of “sectarianism” and “nationalism” in religion to the expansion of the boundaries of understanding spirituality as a universal religious value.The article determines the value of religion in its ontological status, its existentiality, vitality, epistemological meaning, praxeological questionability, in eschatological perspective and hierarchical priority of spirituality, goodness and humanity. Based on this understanding of religion, the authors explicate it in the system of religious values that are implemented in the daily lives of adherents of a particular religion and entire society. The article presents materials of sociological surveys of both international, all-Ukrainian and local levels. The comparative analysis of the received results allows to draw a conclusion about universalization of religious values, to define features of youth perception of religion as a value.
Предпороговые эффекты при воздействии ультрафиолетовых лазерных импульсов на медь и ее сплавы

Published: December 2021

The prethreshold processes on the surface of copper and its alloys are investigated. In the absence of obvious traces of melting, while preserving the metal in a condensed state, under a nanosecond ultraviolet laser radiation energy density of 0.1–1.0 J/cm2, manifestations of high-temperature plastic deformation were observed. These are sliding and cracking along grain boundaries, within which crystallographic slipping was observed. A microprotrusion was formed on the surface of the irradiated zone, which was outwardly similar the distribution of laser radiation in the spot. The height of the microprotrusion reached 1 µm, and sometimes even more. An increase in the number of impacting impulses led to the accumulation of damage. The data obtained are in many ways similar to the acoustoplastic, electroplastic, and magnetoplastic effects. By analogy, we consider it possible to call the discovered effect optoplastic.
Comparing the Effects of Gamification and Teach-Back Training Methods on Adherence to a Therapeutic Regimen in Patients After Coronary Artery Bypass Graft Surgery: Randomized Clinical Trial
Authors: Ghorbani Banafsheh , Jackson Alun C , Noorchenarboo Mohammad , Mandegar Mohammad H , Sharifi Farshad , Mirmoghtadaie Zohrehsadat , Bahramnezhad Fatemeh
Published: December 2021

Background

Patients undergoing coronary artery bypass graft surgery (CABGS) may fail to adhere to their treatment regimen for many reasons. Among these, one of the most important reasons for nonadherence is the inadequate training of such patients or training using inappropriate methods.

Objective

This study aimed to compare the effect of gamification and teach-back training methods on adherence to a therapeutic regimen in patients after CABGS.

Methods

This randomized clinical trial was conducted on 123 patients undergoing CABGS in Tehran, Iran, in 2019. Training was provided to the teach-back group individually. In the gamification group, an app developed for the purpose was installed on each patient’s smartphone, with training given via this device. The control group received usual care, or routine training. Adherence to the therapeutic regimen was assessed using a questionnaire on adherence to a therapeutic regimen (physical activity and dietary regimen) and an adherence scale as a pretest and a 1-month posttest.

Results

One-way analysis of variance (ANOVA) for comparing the mean scores of teach-back and gamification training methods showed that the mean normalized scores for the dietary regimen (P<.001, F=71.80), movement regimen (P<.001, F=124.53), and medication regimen (P<.001, F=9.66) before and after intervention were significantly different between the teach-back, gamification, and control groups. In addition, the results of the Dunnett test showed that the teach-back and gamification groups were significantly different from the control group in all three treatment regimen methods. There was no statistically significant difference in adherence to the therapeutic regimen between the teach-back and control groups.

Conclusions

Based on the results of this study, the use of teach-back and gamification training approaches may be suggested for patients after CABGS to facilitate adherence to the therapeutic regimen.

Are We Missing Something? The Skin Lesions Not Seen in Teledermatology
Authors: Jones Leah , Oakley Amanda
Published: December 2021

Background

The suspected skin cancer electronic referral pathway was introduced in 2017. It requires general practitioners to add regional, close-up, and dermoscopic images to a lesion-specific referral template for a teledermatologist to review and advise on management. The virtual lesion clinic is a nurse-led clinic used since 2010 to obtain high-quality images for teledermoscopy assessment. A limitation of both services is the absence of a full-body examination.

Objective

This study aims to evaluate the number of skin cancers missed during teledermatology assessment.

Methods

This is a retrospective review of skin lesion referrals to dermatology. Suspected skin cancer referrals made in the latter half of 2020 were compared with referrals to the virtual lesion clinic during a similar time period in 2016.

Results

The study included 481 patients with 548 lesions in the 2020 suspected skin cancer cohort that were matched for age, sex, and ethnicity to 400 patients with 682 lesions in the 2016 virtual lesion clinic cohort. A total of 41 patients underwent subsequent specialist review in the suspected skin cancer cohort compared to 91 in the virtual lesion clinic cohort. A total of 20% of the suspected skin cancer cohort and 24% of the virtual lesion clinic cohort were found to have at least one additional lesion of concern. The majority of these were keratinocytic skin cancers; there were 2 and 0 additional melanomas or melanoma-in-situ, respectively. The virtual lesion clinic nurses identified additional lesions for imaging in 78 of 400 (20%) patients assessed in the virtual lesion clinic. The teledermatologist determined (author AO) that 73% of these additional lesions were malignant. Of the 548 lesions, 10 (2%) in the suspected skin cancer group were rereferred, none of which had a change in diagnosis. Out of 682 lesions, 16 (2%) in the virtual lesion clinic cohort were rereferred, 6 (1%) of which had a change in diagnosis.

Conclusions

Patients diagnosed with skin cancer often have multiple lesions of concern. Single-lesion teledermoscopy diagnoses have high concordance with in-person evaluation and histology; however, we have shown that in-person examination may reveal other suspicious lesions. The importance of a full-body skin examination should be emphasized to the referrer.

Healing From a Distance: A Cross-sectional Study on the Diagnostic Reliability of Store-and-Forward Teledermatology (Preprint)
Authors: Chan Erika Kim R , D Melendres Jacqueline Michelle
Published: December 2021

BACKGROUND

Telemedicine delivers health care services between two distant locations through the use of information and communication technology. Several medical specializations, such as dermatology, have incorporated telemedicine into their practice. Since dermatologists are trained to diagnose skin, hair, and nail conditions with a clinical eye, teledermatology may be an alternative when a traditional face-to-face clinic visit is not feasible.

OBJECTIVE

The purpose of this study was to evaluate the diagnostic reliability of teledermatology.

METHODS

A cross-sectional study was conducted among patients from 2 government hospitals. A total of 39 patients were seen in a face-to-face setting and diagnosed by a consultant dermatologist. A written history of their present illness and accompanying photographs were taken and were shown to 3 consultant teledermatologists, who then diagnosed their condition. Two senior dermatology residents then rated the face-to-face and teledermatology diagnoses as either complete agreement, partial agreement, or no agreement. Descriptive statistics was used to summarize the general and clinical characteristics of the participants. The Cohen kappa was used to assess agreement in the evaluations between the teledermatology and face-to-face diagnoses by senior resident raters #1 and #2.

RESULTS

Over 70% of the diagnoses were deemed as either partial or in complete agreement with the face-to-face diagnosis for senior resident rater #1. Similarly, over 80% of the diagnoses were deemed as either partial or in complete agreement with the face-to-face diagnosis for senior resident rater #2. The agreement between the ratings of senior residents #1 and #2 ranged from fair to substantial.

CONCLUSIONS

The findings of the study showed that the diagnostic concordance of in-person clinicians and teledermatologists ranges from fair to substantial, with over 70% of the diagnoses in partial or complete agreement. Although face-to-face consultations remain the gold standard, teledermatology is an important alternative where dermatologic care is not accessible.
A Canadian Weekend Elective Pediatric Surgery Program to Reduce the COVID-19–Related Backlog: Operating Room Ramp-Up After COVID-19 Lockdown Ends—Extra Lists (ORRACLE-Xtra) Implementation Study (Preprint)
Authors: Matava Clyde , So Jeannette , Williams RJ , Kelley Simon ,   ORRACLE-Xtra Group
Published: December 2021

BACKGROUND

The COVID-19 pandemic caused by the SARS-COV-2 virus has resulted in unprecedented challenges for the health care system. A decrease of surgical services led to substantial backlogs for time-sensitive scheduled pediatric patients. We designed and implemented a novel pilot weekend surgical quality improvement project called Operating Room Ramp-Up After COVID Lockdown Ends—Extra Lists (ORRACLE-Xtra).

OBJECTIVE

Our overall goals are to increase patient access to surgery (and reduce the wait list), improve operating room efficiencies, and optimize parent and staff experience.

METHODS

Using the DMAIC (define, measure, analyze, improve, control) framework, we implemented ORRACLE-Xtra in a tertiary care academic pediatric hospital during a quiescent period of the COVID-19 pandemic. We defined process and outcome measures based on provincial targets of out-of-window cases. Parental and staff satisfaction was tracked by surveys.

RESULTS

ORRACLE-Xtra led to 247 patients receiving surgery during the pilot period, resulting in a 5% decrease in the total number of patients on our wait list with Paediatric Canadian Access Targets for Surgery IV (147/247, 59.5%), with 38.1% (94/247) out-of-window of provincial targets. Most of the process and outcome measures were met or exceeded. Overall parental satisfaction was at 95.8% (110/121), with 79% (64/81) of staff reporting satisfaction with working weekends.

CONCLUSIONS

Through the ORRACLE-Xtra pilot program, we have shown that hospitals impacted by COVID-19 can reduce the surgical backlog using innovative models of service delivery in a Canadian context. Sustained funding is critical to achieving more meaningful reductions in wait times for scheduled surgeries over the longer term and needs to be balanced with staff well-being.

Last November 17th, a fire started by a flare, laid waste to 10 ha of the Paicavi urban wetland in Concepción, which is part of the larger Rocuant-Andalién water system. The incident once again raised a red flag for these green spaces, which have been left behind in Chilean urban management and planning in recent decades, on not having been acknowledged as urban green infrastructure, or as part of a broader environmental matrix.
Calidad del entorno urbano y percepción de seguridad de las mujeres. Comparación de dos barrios de Cuenca, Ecuador
Authors: Palacios-Jerves Sofía , Hermida-Palacios Carla
Published: December 2021

Most cities have been planned and built based on a universal subject: a male, healthy, paid, and middle-aged worker. As a result, cities have become an environment that makes social inequalities visible as they hinder the daily lives of the most vulnerable groups. Among these groups are women. In this context, this research looks to present the results of a study that aimed at determining the influence of the quality of the urban environment on the perception of safety for women in two neighborhoods, with different quality of life indices, in the intermediate city of Cuenca, Ecuador. The case studies were the Rio Sol neighborhood, whose quality of life index is one of the highest in the city, and Ciudadela Los Eucaliptos, which, despite being only 500m from the previous one, has a medium-low quality of life index. Methodologically, 3 tools were applied: e-MAPS, to determine the urban quality of the two neighborhoods; an adaptation of the Urban Diagnosis with a Gender Perspective (DUG, in Spanish), to measure the safety perception of women; and non-participant observation. The results showed there are differences in the urban environment quality index between the two neighborhoods, but that these are not directly related to the perception of safety. Non-participant observation suggests that there are other factors that make up neighborhood life, that affect women's perception of safety.
Individual solutions to collective problems: the paradoxical treatment of environmental issues on Mexican and French YouTubers' videos
Authors: Lartigue Cecilia , Carbou Guillaume , Lefebvre Muriel
Published: December 2021

The impact of human activity on our planet is undeniable. However, this matter of fact is not fully understandable without analyzing the narratives through which people make sense of it. In this study, we aim to describe the narratives present in environmental discourses of Mexican and French YouTubers' videos. This corpus is intended to show how environmental issues are framed in the ever-growing discursive arena of entertainment and “influencing” streaming video. We set out to perform a cross-country comparison, with the purpose of contributing to the discussion of whether environmental discourse is country-specific or shared by various nations and, possibly, even global. Our study contributes to the understanding of the social construction of the environment via these discourses. Our main result points to a paradoxical treatment of environmental issues: the YouTubers of our sample represent them as collectively induced problems, but seem to mainly believe that individual-based solutions would resolve them. More broadly, our study suggests a tendency to the individualization and, therefore, the depoliticization of environmental issues as well as a globalization of the environmental discourses in YouTubers' videos.
Structures of intransitive competition network affect functional attributes of plant community under nitrogen enrichment
Authors: Sun Qingqing , Yang Junjie , Yang Fengyan , Zhao Yuying , Wei Cunzheng , Zhang Guangming , Han Xingguo , Li Jinshan
Published: December 2021

Atmospheric nitrogen (N) deposition is a potential danger factor for
grassland ecology, and will cause unpredictable consequences to plant
communities. However, how plant species interactions response to N
enrichment and then affect ecological functions are not fully known. We
investigated how intransitive competition network was related to the
functional attributes of plant community under a 13-years N-deposition
experiment. Results showed that intransitive competition network was not
a single structure, but a complexly interwoven structure of various
simple structures. Nested work was more common, accounting for 76.96%,
and gained new species at a higher colonization rate than short network
did. The network had a long-term mechanism to maintain the small-scale
Alpha diversity, and a significant lag effect on the large-scale Gamma
diversity. Under the conditions of N ≥ 2 g N·m-2·year-1, without mowing
and under high fertilization frequency, the increase of network
complexity significantly decreased plot biomass gradually. The
relationship between biomass and network complexity is quadratic curves,
also between abundancy and the complexity, but with the opposite bending
directions, which indicated that biomass and abundance were
complementary to each other, which may be a mechanism of maintaining the
relative balance of species competition. In addition, the decrease of
species asynchronism changing with the increase of N-enrichment
gradually destroyed ecosystem stability. However, at medium N
enrichment, intransitive network counteracted the negative effects of N
enrichment and maintained or even improved the biomass ecosystem
stability. Our results suggested that intransitive competition network
is an internal mechanism of self-restoration of a grassland ecosystem.
Under nitrogen enrichment conditions, competitive networks complexity is
reduced, leading to a reduction in species diversity. These analyses
emphasize the important role of intransitive network structure to
stabilize grassland ecosystem. In order to achieve sustainable
development of grassland, it is indispensable to control nitrogen
addition rate.
Matrix methods for perfect signal recovery underlying range space of operators
Authors: Neyshaburi Fahimeh Arabyani , Farshchian Ramin , Kamyabi-Gol Rajab Ali
Published: December 2021

The purpose of this work is to investigate perfect reconstruction
underlying range space of operators in finite dimensional Hilbert spaces
by a new matrix method. To this end, first we obtain more structures of
the canonical $K$-dual. % and survey optimal $K$-dual problem under
probabilistic erasures. Then, we survey the problem of recovering and
robustness of signals when the erasure set satisfies the minimal
redundancy condition or the $K$-frame is maximal robust. Furthermore,
we show that the error rate is reduced under erasures if the $K$-frame
is of uniform excess. Toward the protection of encoding frame (K-dual)
against erasures, we introduce a new concept so called $(r,k)$-matrix
to recover lost data and solve the perfect recovery problem via matrix
equations. Moreover, we discuss the existence of such matrices by using
minimal redundancy condition on decoding frames for operators. We
exhibit several examples that illustrate the advantage of using the new
matrix method with respect to the previous approaches in existence
construction. And finally, we provide the numerical results to confirm
the main results in the case noise-free and test sensitivity of the
method with respect to noise.

O artigo tem como objetivo identificar a qualidade dos gastos públicos dos municípios catarinenses. A população da pesquisa compreende os 295 municípios do Estado de Santa Catarina. A pesquisa é descritiva, realizada por meio de estudo bibliográfico e documental, com abordagem quantitativa, sendo propostas três hipóteses. A coleta dos dados ocorreu em duas fontes. A primeira, referente aos indicadores de resultado realizou-se em instrumento preexistente Sistema de Indicadores de Desenvolvimento Municipal Sustentável, desenvolvido pela Federação Catarinense de Municípios. Na segunda, a coleta dos dados foi realizada em documentos de prestação de contas dos municípios disponíveis no portal do Tribunal de Contas do Estado de Santa Catarina. Conclui-se pela elevada quantidade de municípios com IQGP inferior a 1,000 em diversas funções analisadas. Tais valores representam que esses municípios não conseguiram obter um retorno proporcional, medido em unidades de bem-estar, a partir das despesas realizadas na função, mensuradas em unidades de insumo. É evidente que cada município tem sua realidade e contextos social, econômico e político, distintos.

Published: December 2021

This study examines the effect of the cultural system on the disclosure of corporate social responsibility by companies in the energy sector. The survey analyzed a sample of 62 leading energy companies from 25 countries. The dependent variable is the level of environmental disclosure of the companies. The independent variables are composed by the cultural system of the analyzed countries, according to the Hofstede cultural dimensions. The data were analyzed using descriptive, inferential statistics, correlation, and regression of panel data. The findings show that in more individualistic and masculine cultures, companies disclose more CSR information. It was found that companies based in cultures with a higher level of indulgence and with a greater orientation for the long term tend to have greater environmental disclosure. The results show that the level of disclosure of corporate social responsibility is different depending on the country's cultural system. There are institutional pressures, which encourage companies to publish a more complete sustainability report. The results of this study have academic and managerial implications.

Published: December 2021

The aim of this study was to develop a stable hydrogel carrier system for
thyme essential oil (TEO) that could protect its sensitive polyphenol
compounds. The impact of wall material (soy protein and alginate) on
encapsulation efficiency and thymol release in simulated gastrointestinal
conditions, was investigated. The release of thymol was ~ 80 % and 20 % in
simulated gastric and pancreatic solutions, respectively. Thyme essential
oil plays an important role as an antimicrobial and antioxidant agent.
Results indicated that encapsulated TEO inside the hydrogel matrix exhibited
antioxidant activity demonstrated by CUPRAC and ABTS analysis, even after
thermal treatment of the beads, indicating the metal chelate effect as
dominant. In vitro antimicrobial activity of encapsulated TEO has been
studied against several pathogenic microorganisms such as Escherichia coli,
Staphylococcus aureus, Bacillus cereus and Candida albicans. Beads coded as
Ca-A1.5/SP1.5 showed anti-Candida albicans activity, while modified bead
formulations Ca-A1.5/SP1.5* and Ca-A1.5/SP0.25** showed bactericidal
activity against Escherichia coli and Staphylococcus aureus.

Published: December 2021

The water quality of the San Camilo and Mojahuevo estuaries was monitored in
the months of April (rainy season) and June (dry season) of 2016. The water
of the Mojahuevo estury presented in both seasons the lowest values of
turbidity between 17.20 and 33.70 UNT, biochemical oxygen demand being in a
range between 14.00 and 19.00 mg/L, zinc content (0.02-0.05 mg/L) and copper
content (0.07 mg/L), ammonia content (0.21-0.35 mg/L), fats and oils
(0.23-0.29 mg/L), phosphates (0.39-2.34 mg/L) and nitrates (0.84-2.29 mg/L),
while the water of the two estuaries San Camilo and Mojahuevo (rainy season)
showed similar phenolic content (0.019 mg/L). The results showed that the
Mojahuevo estuary presented the high quality of water recommended for being
used in productive process like aquaculture due to the low presence of
pollutants.
Degradation of an organophosphorus insecticide in aqueous medium by Electro-Fenton process
Authors: Assassi Mirvet , Madjene Farid , Amrane Abdeltif
Published: December 2021

This work proposes the remediation of toxic and/or refractory pollutants,
such as the organophosphorus insecticide (Phosmet) which cannot be
completely degraded by conventional methods like biological treatment,
adsorption, flocculation, electro-flocculation, reverse osmosis,
ultrafiltration, coagulation. However, these techniques have some
disadvantages such as incomplete removal, therefore, the Electro-Fenton
process was used. The major factors affecting the removal of Phosmet, namely
the current intensity, catalyst concentration (Fe3+), temperature solution,
nature of the electrolytes and oxygenation duration of the solution were
studied in this work. The optimal operating conditions appeared to be:
current intensity 200 mA, 0.5 mmol L-1 of Fe3+, T= 20?C, pH =3 using Na2SO4
(50 mmol L-1) as supporting electrolyte and an oxygen supply throughout all
the experiments (120 min). Under these optimal conditions, the removal
efficiency of the phosmet was 88%.

This study aims to evaluate the chemical composition and biological effects
of an endemic Algerian species Myrtus nivellei belonging to the Myrtaceae
family. The aerial parts of the plant were submitted to hydrodistillation
and analysed with gas chromatography - mass spectrometry (GC-MS). This oil
was yielded 0,75% (w/w). The GC-MS revealed that 1,8 cineole is the most
abundant component (53,44%) while other compounds were present in high
contents: 2,2,6,7-tetramethyl-10-oxatricyclo [4.3.0.1(1,7)]- decan-5-one
(11,73%), trans ocimene (7,54%), linalyl propirionate (6,81%) and lavandulyl
acetate (5,24%). In addition ethanolic extract of studied plant was
prepared. Total phenol, tannin, flavonoid, and condensed tannin?s contents
were determined using Folin-Ciocalteu, aluminum chloride and vanillin
colorimetric methods, respectively. Three tests were used for the
investigation of antioxidant activity of both extract and oil. Strong
antioxidant activity was shown mainly by crude extract. Antibacterial
screening was evaluated against Gram positive and Gram negative bacteria.
Ethanolic extract and oil were active especially against Staphylococcus
aureus.
Evaluation of the suitability of human settlements in Qingpu district, Shanghai
Authors: Luo Yu-Kun , Yang Xiao-Hua
Published: December 2021

In recent decades, people's attention to human settlements has been increasing. However, the research on the evaluation method of the suitability of human set-tlements is still in the exploratory stage, and there is no universally accepted evaluation method worldwide. Considering the uncertainty in the evaluation index system, this paper combines the set pair analysis theory and the Logistic model to construct a new evaluation model of the suitability of human settlements and applies the model to the dynamic evaluation of the suitability of human settlements in Qingpu district from 2007 to 2016. The evaluation results show that the overall suitability of human settlements in Qingpu district is on the rise. Based on the analysis of the evaluation results, this paper puts forward some opinions on the development plan of Qingpu District and verifies the validity of the constructed model.
Understanding and Supporting Parents of Academy Footballers
Authors:   , Newport Rachael A.
Published: December 2021

The aim of this thesis was two-fold: firstly, to gain an in-depth understanding of the experiences of academy football parents and identify support that may be beneficial, and; secondly, develop, implement, and evaluate programmes of support for parents of academy footballers. Two action research cycles were carried out to address these aims. The exploration and reflection phases of action research cycle one, sought to understand parents’ experiences and offer recommendations for supporting parents within youth academy football. An instrumental case study of one football academy was conducted, with data collected over an eight-month period through interviews, focus groups, informal conversations, reflexive diary, fieldwork, and observations. It was recommended during this study that parents may benefit from a programme of support, along with a series of cultural changes that focused on enhancing their experience. Subsequently, based on these initial findings, reflections, and recommendations made, a programme of support for academy parents, combined with cultural changes, was developed and implemented. The initial programme was evaluated using interviews, observations, informal conversations, practitioner reflections, fieldwork, and an online survey. Overall, parents found the sessions useful for gaining information and benefitted from talking with other parents. However, attendance was poor and some academy staff did not buy-in to the proposed cultural changes. As such, following a period of reflection and building on the findings of the first action research cycle, a second programme was planned and delivered. This was a condensed programme, comprising one 90-minute face-to-face session and booklet. Further cultural changes were also promoted. This programme was evaluated using an online survey, observations, fieldwork, informal conversations, and practitioner reflections. As with the first programme, parents suggested that the condensed version was useful for increasing their knowledge, they enjoyed learning from others, and gained social support. Despite the condensed programme, the issues pertaining to attendance and buy-in continued. Based on the findings of the two action research cycles, general suggestions for working with parents and developing parent support interventions are presented.
Comparing the Outcomes of the Different Teaching Modes: All-in-Person, Hybrid, and Online, for Different Student Demographic Groups in a Business School
Authors: Moodie Douglas Rome
Published: December 2021

The concept of hybrid education is spreading. Far less research has been done comparing hybrid teaching to online and F2F teaching. Nearly all this research assumes that there is no difference in the students entering F2F, Hybrid, or online sections of a course. This study used data from four years of courses that were taught in Coles College of Business at Kennesaw State University. This data set with individual student and course outcomes, included full student demographics including previous university GPA. The results showed for all demographics, hybrid course sections gave better final course grades than online sections, which in gave better final grades than F2F sections. However, for instructors who taught Hybrid courses also gave higher course GPAs for F2F sections than those who did not teach hybrid.

The aim of the study – to investigate the taxonomic composition, qualitativemicroecological indicators (index of constancy, frequency of occurrence, indices of speciesrichness of Margalef, species diversity of Whittaker and species dominance of Simpsonand Berger-Parker) and the immunosuppressive eﬀect of causative agents of calculouspyelonephritis on the activity of the complement system, lysozyme and inhibition of themain immunoglobulin classes (IgM, IgA).Material and methods. Microbiological (bacteriological and mycological) urineexamination was carried out in 30 men aged 37-65 years (48.81 ± 4.27 years), patientswith calculous pyelonephritis. The ecological method was used to reveal the mechanismsof colonization of the biotope by microbiota. The adhesive properties were studied onnative human erythrocytes of group I (0I). Anti-immunoglobulin activity was studied bythe method described in the work of I.S. Gaidash, etc.Results. Out of 30 samples of the research material, 34 strains of opportunistic gramnegative and gram-positive bacteria were isolated and identifed. The majority (86.67%)had a monoculture of enterobacteria, enterococci, associations consisting of two taxonswere found in 13.33% of patients. It has been shown that 97.06% of isolated and identifedstrains from the urinary tract exhibit adhesive activity of varying degrees of activity. Onestrain of S. saprophyticus also exhibits adhesive activity (the average adhesion index is1.83 ± 0.09), which is considered as a non-adhesive strain. All strains of enterobacteriaand gram-positive cocci that persist on the mucous membrane of the urinary tract ofmen with infectious and inﬂammatory processes of the urinary tract with calculouspyelonephritis inhibit (P <0.05) immunoglobulins of class A (IgA).Conclusions. The infectious and inﬂammatory process on the mucous membranes of theurinary tract in men with calculous pyelonephritis is caused by facultative anaerobicgram-negative enterobacteria and gram-positive cocci. The presence of an infectious andinﬂammatory process is confrmed by an acceleration of the erythrocyte sedimentationrate by 76.67% and other clinical and laboratory studies. Pathogenicity factors arerevealed in isolated and identifed opportunistic taxons, that determine the initial stagesof the infectious and inﬂammatory process (cytoadhesion and colonization of the urinarytract mucosa), inhibit the functional activity of class A and M of immunoglobulins.
Risk of arterial hypertension development due to T393C gene polymorphism of α-subunit of G-protein
Authors: I. A. Dudсhenko
Published: December 2021

According to foreign researchers, T393С gene polymorphism of α-subunit of the G-protein (rs7121) affects the sympathetic-adrenal system and the risk of hypertension. There are also data on the dependence of the manifestations of this polymorphism on the associated risk factors. However, these data are contradictory, which may be explained by ethnic differences in patients. In Ukraine there were no studies on this issue. We have studied 166 hypertensive patients and 90 healthy individuals. Determination of the polymorphism was performed by polymerase chain reaction with subsequent analysis of restriction fragments. The study found no statistically significant difference in the distribution of genotypes T393T, T393С, С393С in patients with hypertension and healthy subjects (p>0,05). The risk for hypertension in carriers of genotypes T393T + T393С relatively to С393С genotype was not significantly different (OR=1,44, 95% CI 0,74-2,80; p=0,283). During the analysis of the effect of smoking on the manifestations of T393С gene polymorphism α-subunit of the G-protein, no statistically significant difference were found (p>0,05). T393C gene polymorphism of α-subunit of G-protein did not affect the risk of hypertension.
Hormonal adaptation of the fetal-placental complex in women with preeclamsia
Authors: S. Y. Kosilova
Published: December 2021

The course of pregnancy and labour in women with preeclampsia considerably determines maternal and perinatal morbidity and mortality. The study of the hormonal function of the fetal-placental complex appears to be rather topical in this respect. The research conducted gave the evidence that the pregnant with preeclampsia develop placental dysfunction. It results in a decrease of hormone production in the fetal-placental complex, development of complications during gestation, labour, conditions of the fetus, and requires a hormone-correcting therapy.

The influence of melatonin on the state of the glutathione system of the rat liver under the conditions of subacute alcoholic intoxication
Authors: N. V. Davydova
Published: December 2021

The investigations of certain parameters of glutathione system in the liver of rats under the conditions of subacute alcohol intoxication revealed a decreased content of reduced glutathione and glutathione peroxidase activity as well as an activation of glutathione-S-transferase activity. An oral administration of “Vita-melatonin” against a background of subacute alcohol intoxication in a dose 5 mg/kg during 10 days prevented the changes of the parameters under study.

Published: December 2021

In order to investigate the efficiency of a statin therapy (group 1, atorvastatin) and metabolic treatment (group 2, trimetazidine and MagneB6) 164 patients with signs of subclinical atherosclerosis were examined depending on an increase of intima-media thickness more than 0.9 mm in conditions of the pair echocardiography and stress tests (treadmill) with long follow-up observation (3 months and 1 year). Evaluation of the remodeling process in both treatment groups (statin/metabolic therapy) indicates a tendency, after 3 months of treatment, to increase the number of cases withincreased ejection fraction (EF) in group 1 (p<0,05) in unreliable predominance of cases not altered EF in group 2 (p>0,1) with the increase in the incidence of concentric remodeling of the left ventricle twice as often in group 2 (p>0,05), three times – in 3 months (p>0,5) after 1 year (p<0,05). The increase in exercise tolerance was registered in group 1 during the treatment period of 3 months (p<0,05) and 1 year (p<0,01) in contrast to group 2 with no changes in rate for 3 months (p>0,5) with an increase after 1 year (p<0,05). Thus, the differences in influence of statin therapy and metabolic treatment on the parameters of central haemodynamics and response to stress tests for subclinical atherosclerosis have been established.

Published: December 2021

The purpose of the study was to analyze the prevalence of comorbid pathologies in patients with chronic obstructive pulmonary disease (COPD) and the effect of comorbidity on the course of disease in the light of existing recommendations on supervision of COPD patients and from the standpoint of our own experience. We made an analysis of prevalence of arterial hypertension, coronary heart disease, diabetes mellitus, and psychosomatic disorders in patients with COPD. The analysis of the world data revealed that comorbidity in patients with COPD was diagnosed much less frequently, which may be preconditioned with the problems of under-diagnosis for COPD itself. At the same time, patients with comorbid conditions were diagnosed a number of serious clinical syndromes that predetermined the course and severity of the disease. Administration of beta-blockers to patients with COPD is effective and safe and may positively influence the prognosis for those patients.
