Methodology of research of the constitutional and legal status of the Ukrainian people
Authors: Kolodii Anatolii M. , Kolodii Olexii A. , Petryshyna Maryna O.
Published: January 2022

The relevance of the topic “constitutional and legal status of the Ukrainian people” is seen, first of all, in the fact that the understanding of the Ukrainian people of their essence, their political and legal status, in the context of awareness of their own legal personality, principles, powers, guarantees, that is, certain elements included in the content of the constitutional and legal status at the present stage of development and development of Ukraine as a democratic, social and Legal country, is very important, appropriate and, for the political, legal and other systems of any country, system-forming. It should also be noted that this issue, despite its fundamentality and scientific prospects, is not sufficiently doctrinairely studied by Ukrainian scientists. This is due to many determinants, of which two factors are the most obvious. First, the dominance of doctrinal approaches in Ukrainian legal science, which did not recognise the existence of the constitutional and legal status of the Ukrainian people as a whole. It was considered that only individuals and legal entities can be granted legal status. Secondly, Ukrainian scientists have traditionally preferred to study established institutions, primarily direct democracy, which are directly regulated in Chapter III of the Constitution of Ukraine, that is, elections and referendums. The aim is to clarify the methodological basis for studying the constitutional and legal status of the Ukrainian people. Based on the obtained conclusions and generalisations, a methodological basis for studying the constitutional and legal status of the Ukrainian people has been developed

Physico-chemical monitoring of biodegradation of furfural from oil industry effluents from the Arzew refinery (Oran) Algeria
Authors: MOUFFAK Amina-Afaf
Published: January 2022

Furfural is one of the petroleum products posing a potential danger to the environment and human health. However, the decontamination of these pollutants released into the environment is primarily governed by biodegra-dation processes. This study is based on biodegradation kinetics at increasing concentrations of furfural by natural mixed culture in order to assess the potential of this process in the elimination of furfural from petrochemical effluents from the ARZEW refinery. This biodegradation was measured through physicochemical parameters such as pH, electrical conductivity, con-centration of hydrocarbons, the chemical oxygen demand (COD), biochemi-cal oxygen demand (BOD5) and the concentration of furfural. The results obtained show at a concentration of 250ppm of injected furfural: a decrease in pH 4.9 and an increase in other parameters (conductivity 3450 μS.cm-1, HC 102 mg / l; furfural 210 ppm, COD 327mg / l, BOD5 98mgO2 / l. The study findings indicated that the injection of these effluents with concentrations greater than 180 ppm leads to values of pH, EC, HC, Furfural, COD, BOD5 which do not comply with direct discharge standards and disrupt biological treatment. The high levels of furfural not only cause a pollution problem but can also disrupt the functioning of bacteria at the biological treatment level. Therefore, dilution with the filtration wash water before switching to biologi-cal treatment is recommended in order to reduce the concentrations below 180 ppm.
Hemophiliacs A patients from Algeria without mutation or rearrangement in the F8 gene
Authors: Abdi Meriem  , Zemani-Fodil Faouzia
Published: January 2022

Hemophilia A (HA) is the most severe X-linked inherited bleeding disorder caused by hemizygous mutations in the F8 gene. Several F8 mutations are responsible of HA including intron 1 and 22 micro-inversions, large and small deletions, insertions, duplications, and point mutations. In a previous study, we determined the molecular causes of HA in 85% of patients group studied. However, no mutation were found in three unrelated patients origi-nating from Western Algeria. In the present study, we sought to characterize the molecular origin of HA in three patients by investigating rearrangements in the F8 gene using the MLPA method. Comparaison between case results and healthy controls showed absence of deletions or duplications in the F8 gene in these three hemophiliacs A patients. This finding has already been reported in many studies where any F8 mutation or rearrangement has been identified. Further analysis are required in order to determine the molecular origin of the disease in these families. It would be very interesting to look for deep intonic mutations and to study epigenetic mechanisms as well as DNA methylation and miRNAs.

Published: January 2022

Bacterial endophytes colonize an ecological niche which is unexplored site makes them suitable to produce pharmacologically active substances with vast biotechnological potential therefore, xerophytes were chosen to isolate the endophytes. In the present study forty endophytic bacterial isolates were isolated from xerophytic plants grown near poultry farms and feather dumping sites. Of them eight isolates showed zone of hydrolysis and the maximum zone of hydrolyisis of 36mm was with VRCS-4 on skimmed milk agar. This isolate exhibited efficient feather degradation and was identified as Aneurinibacillus aneurinilyticus based on its morphological, biochemical test and molecular sequencing method. The isolate was deposited in NCBI with an accession number MW227423.The isolate showed maximum en-zyme activity of 140.24U/ml at 72h, pH 7.5 and 40º C at 140 rpm. Chicken feather 1% (w/v) used as a sole source of carbon and nitrogen. Feather deg-radation by A.aneurinilyticus VRCS-4 showed 90% degradation in feather meal broth. Ours appears to be the first report on keratinase production by endophytic bacteria from xerophytic plant (Opuntia ficus -indica).

Authors: Athmani Nora , Allaoui Amine  , Nasri Moncef  , Boualga Ahmed
Published: January 2022

Hypercholesterolemia is a major risk factor of cardiovascular diseases (CVD). A limited number of experimental studies have shown that sardine protein hydrolysates (SPH) could be a very useful natural compound to prevent hy-percholesterolemia by both improving the lipoprotein profile and modula-ting oxidative stress. In the present study, the effect of short and long term treatments with SPH were examined on serum lipid contents, lipid peroxida-tion and antioxidant enzymes activities in rats fed cholesterol-enriched diet. At day 0, rats were divided into five groups. The group of day 0 was the stan-dard group, and the four remaining groups were divided into two parts of two groups each consuming for 14 or 28 days an hypercholesterolemic diet, and treated (HC-SPH) or not (HC) by gavage with SPH. Compared with day 0, serum TC contents were increased at day 14 and remained unchanged at day 28 in HC-SPH group. These values were decreased in HC-SPH versus HC. Liver and heart TBARS concentrations were increased at day 14 then diminished at day 28 in HC-SPH group. Liver and heart SOD and CAT activities were decrea-sed at short term then remained unchanged at long term in HC-SPH group. In addition, these activities were enhanced in HC-SPH versus HC. In conclusion, these results indicate the potential effects of short and long term treatments of SPH to improved cholesterolemia and reduced radical attack in rats fed high-cholesterol diets.

Authors: Boaheng Isaac
Published: January 2022

An African Background to the Old Testament is a brief introduction to the geographical, social, economic, political and religious backgrounds of the Old Testament from an African viewpoint. It is written to help (African) Bible students to have access to the right background information required for proper interpretation of Scripture within the African setting. The seven-chapter book, after a thorough examination of the geographical, social, economic, political and religious backgrounds of the Old Testament from an African perspective contends that Old Testament scholarship in Africa must be carried out by those with adequate understanding and experience of the African socio-cultural context and must be done through proper interaction with that context. The Book is written in a non-technical way to make it accessible to everyone. Every chapter is organized thematically in sub-headings. Each chapter also ends with a recap of the main points discussed and review questions to allow the student to reflect on what has been discussed before proceeding to the next chapter. Universities and Seminaries can use it as a textbook for undergraduate and postgraduate courses in Old Testament Studies.
Nurses’ View towards the Use of Robotic during Pandemic COVID-19 in Indonesia: A Qualitative Study
Authors: Taryudi Taryudi , Lindayani Linlin , Purnama Heni , Mutiar Astri
Published: January 2022

Background: Rapid advances in artificial intelligence and robotics have alleviated difficulties for patients, hospitals, and the industry as a whole. However, the health care system is identically human-centered at its core, and many healthcare professions may not be ready to work with robots. Understanding nurses' views toward robotics can help integrate robotic technologies into future patient care.
Objectives: This study aimed to explore how nurses view using robotics during the COVID-19 pandemic.
Methods: This study used a qualitative descriptive technique to registered nurses who provide direct care to the patients with COVID-19 recruited from two hospitals in Indonesia. Purposive sampling was used to select respondents with criteria of those who had worked for at least one year and were willing to participate—the analysis used qualitative content analysis.
Results: A total of 20 female nurses with an average age of 32.8 ± 4.0 years participated in this study. The qualitative findings revealed three themes with nine sub-themes, namely the use of robotic in nursing care (sub-theme: reducing the risk of COVID-19 transmission, monitoring patients remotely, and helping in providing care), the burden of using robotic in nursing care (sub-theme: digital literacy in nursing care, culture difference in providing care, changing care practice habits, and safety concern, and attitude toward robotic in nursing care (sub-theme: negative response).
Conclusions: This study explored nurses' views on the usage of robotics during the pandemic COVID-10. It implies that a strategic plan would have many benefits and limitations, such as nursing care burden, negative attitude, and cultural awareness.
Risk Factors of Stunting in Children Aged 6–59 Months: A Case-Control Study in Horticulture Area
Authors: Yushananta Prayudhy , Ahyanti Mei , Anggraini Yetti
Published: January 2022

BACKGROUND: Stunting is a critical public health problem in Indonesia because it affects cognitive and physical development and contributes to child mortality.

AIM: This study aims to identify risk factors for stunting in children aged 6–59 in the horticultural area.

METHODS: A casecontrol study was conducted to compare previous exposure between stunted children and non-stunted children. Measurements and interviews were conducted with 160 participants (120 controls and 40 cases), including mothers or caregivers. SPSS was used for χ2 statistical analysis, multiple logistic regression, and odds ratios.

RESULTS: The study identified four risk factors for stunting: children who were born short (adjusted odds ratio [AOR] = 17.57; 95% confident interval [CI]: 5.02–61.51), LBW (AOR = 4.35; 95% CI: 1.38–13.78), and got a low protein intake (AOR = 4.96; 95% CI: 1.22–20.26). Significantly, a relationship between stunting and access to sanitation was also found (AOR = 6.06; 95% CI: 1.25–29.35).

CONCLUSIONS: The risk factors for stunting in children aged 6–59 are related to nutrition during pregnancy and the child’s quality of food. Nutrition interventions should emphasize improving the nutritional status of pregnant women and children and women empowering to affect access to resources and allocations for children’s nutrition.
Polyphonie musicale et littéraire. Un double transfert sous-jacent entre Claude Perrault et Daniel Casper von Lohenstein à la fin du XVII e siècle
Authors: Previšić Boris
Published: January 2022

Durant la Querelle des Anciens et des Modernes, deux définitions de la polyphonie cohabitent : une polyphonie musicale, qui sert à démontrer la supériorité des Modernes, et une polyphonie comprise comme forme narrative et dialogique, qui relève de la perception acoustique. Pour envisager ce transfert musico-littéraire, le présent article interroge un manuscrit de Claude Perrault, texte à travers lequel l’auteur déploie un discours sensualiste. La supériorité des Modernes éclate au regard des moyens rhétoriques allégués et des stratégies narratives mises en place. Le traité de Perrault s’éclaire ainsi au vu d’un contexte intellectuel et social spécifique : discussion menée avec son frère Charles, polyphonie littéraire satirique de Daniel Casper von Lohenstein, discours otologique, goût esthétique de la fin du xviie siècle.
La maxime de la médisance
Authors: Carraud Vincent
Published: January 2022

Cette note s’efforce, dans un premier temps, de caractériser l’originalité de l’analyse que Pascal fait de la calomnie dans la XVI e  Provinciale, en révélant la contradiction qu’elle recèle entre son principe et son effet : « tant le mal est contraire à soi-même, et tant il s’embarrasse et se détruit par sa propre malice ». Car, en exemptant la calomnie d’être un péché, l’« étrange maxime de la médisance » ruine le crédit que le médisant suppose avoir auprès de celui qui en est l’auditeur. Dans un second temps, qui en est la conséquence directe, nous rétablissons le texte d’une citation de Manilius relevée par Pascal dans un brouillon de la XVIe Provinciale, Laf. 960. Il faut lire non pas, comme dans toutes les éditions des Pensées, « Fecitque cadendo undique me cadere, En tombant de tous côtés, il m’a fait tomber », mais, conformément à l’Astronomicon : « Fecitque cadendo undique ne caderet ». Entendons : en tombant de tous côtés dans le péché, c’est-à-dire en calomniant sans retenue, le calomniateur a fait que son auditeur, ne le croyant pas, n’y tombe pas.
Victimes d’abus dans l’Église. Pour une théologie de la vulnérabilité, de la responsabilité et de la guérison
Authors: Guillon Béatrice
Published: January 2022

Le caractère massif des abus dans l’Église révélé dans le récent Rapport Sauvé oblige à regarder à nouveaux frais la théologie du salut dont le corps ecclésial vit en mode sacramentel. Dieu a-t-il pu abandonner à la mort ceux et celles qui ont cherché son visage en vérité et s’en étaient remis avec confiance à l’Église ? On réfléchira donc sur le statut théologique de la vulnérabilité, sur la radicalité des conseils évangéliques qui ont autorisé les abus, sur le pouvoir dans l’Église qui l’a emporté sur la recherche spirituelle authentique, mais on osera aussi proposer de considérer le mystère pascal dans ce drame.
L’imposition des mains dans le sacrement des malades, puissance de la guérison dans le corps ecclésial
Authors: Malisoux Christophe
Published: January 2022

L’imposition des mains lors du sacrement des malades a-t-elle seulement une efficacité spirituelle ou doit-elle conduire à la guérison corporelle ? Pour comprendre la réalité et le sens de ce geste, on examinera l’action du Christ thaumaturge dans les évangiles, la perspective pneumatique du sacrement et sa dimension ecclésiale. On pourra alors saisir l’originalité de la gestuelle sacramentelle par rapport aux techniques de médecine alternative comme le Reiki.

In this paper, we consider the three-dimensional non-autonomous micropolar equations with damping term in periodic domain $ \mathbb{T}^{3} $. By assuming external forces satisfy certain condtions, the existence of pullback $ \mathcal{D} $-attractors for the three-dimensional non-autonomous micropolar equations with damping term is proved in $ V_{1}\times V_{2} $ and $ H^{2}\times H^{2} $ with $ 3 < \beta < 5 $.
Use of Anthropogenic Nest Materials by Black-Crested Titmice Along an Urban Gradient

Published: January 2022

Numerous avian species use anthropogenic materials in constructing nests, particularly in urbanized environments. Researchers have demonstrated anthropogenic materials, including plastics, to have both beneficial and harmful effects on survival and reproduction. During the spring of 2018, we collected 45 black-crested titmouse Baeolophus atricristatus nests in San Marcos, Texas, with two objectives: 1) to assess and compare the mass and proportion of nest materials along an urban gradient and 2) to examine the relationship between nest materials, clutch size, and hatching success. We categorized each nest based on collection location as urban, residential, park, or rural and separated nest materials into six categories: leaves, snake skin, twigs, moss, plastic, and nonplastic artificial materials. We then compared raw mass and proportion of mass of each nest material among urbanization categories. Nests in the urban category were 1.6–1.9 times lighter in mass than nests in other locations along the urban gradient (P = 0.01) and contained 4–5 times greater proportion, but not mass, of plastic compared to nests in all other locations. Nests in residential areas contained the greatest mass of combined anthropogenic materials. Neither clutch size nor hatching success differed based on urbanization category, nest mass, or proportions of anthropogenic or natural nest materials. The differences in mass of nests and increased proportion of plastics could have been due to a lack of natural nesting materials; however, we did not estimate availability of nesting materials at any location. Results add to the growing literature that the use of anthropogenic materials in nests varies across an urban gradient, and the effect of anthropogenic materials on nesting parameters varies among species.

Authors: Mainardes Jefferson
Published: January 2022

O artigo apresenta uma análise de 70 questionários online respondidos por líderes de Grupos de Pesquisa de Política Educacional, de grupos cadastrados no Diretório de Grupos de Pesquisa no Brasil (DGPB/CNPq). O referencial teórico foi estruturado a partir de conceitos da teoria de Bourdieu e, também, nas noções de comunidades epistêmicas e comunidades de práticas. Concluiu-se que: a) há um consenso que os Grupos de Pesquisa são fundamentais no processo de formação de pesquisadores; b) as principais dificuldades referem-se à falta de tempo para os estudantes participarem em todas as atividades do grupo, ausência de financiamento e falta de infraestrutura; c) os Grupos de Pesquisa necessitam ser mais valorizados nas universidades e pelos órgãos de fomento; e d) há necessidade da realização de mais pesquisas, principalmente voltadas à análise da estrutura e do funcionamento de grupos na grande área de Ciências Humanas e Sociais e também da área de Educação.

Published: January 2022

O artigo analisa resultados de uma pesquisa-intervenção que estuda as contribuições e os limites de um Programa Híbrido de Mentoria (PHM) para o desenvolvimento profissional de professores experientes e iniciantes. Elege como foco de análise as demandas formativas dos 199 professores iniciantes e ingressantes que se inscreveram no PHM entre 2018-2020. Tem como aportes teóricos: Reali, Tancredi e Mizukami (2008; 2010), Cruz, Farias e Habold (2020), Garcia (1999), Vaughan, Cleveland-Innes e Garrison (2013). Os achados revelaram que as demandas formativas se aproximam, com forte ênfase na sala de aula, às práticas pedagógicas e à troca de experiências. Porém, para os iniciantes estão mais diretamente atreladas ao contexto da sala de aula, ao aprender como ensinar, ao saber relacionar teoria e prática, ao conteúdo específico, enquanto para os ingressantes estão direcionadas ao aprimoramento profissional, aos aspectos mais avançados da carreira, que não dizem respeito apenas à sala de aula.
The Cranio-Sacral Approach for Defining Embodied “Coherence”
Authors: Botte Patrick
Published: January 2022

The premise of this book is that applying principles of electromagnetic (EM) resonant coherence to the media field is the key to generating a more harmonious culture. The advent of new types of sensors, quite affordable and increasingly sensitive, now provides an easy way to measure frequencies and rhythms of the body and to create applications that visualize brain waves and waves extracted from cardiac parameters. The term “coherence” used in physics defines the correlations of a wave system. More recently, this term has been used increasingly to define an inner state of “centering” and harmony that presents as relaxation, stress management, deep meditation, and state of transcendent bliss. The craniosacral approach provides important information on how that can be achieved.
Gamers as Homeopathic Media Therapy
Authors: Schafer Stephen Brock
Published: January 2022

Mainstream Western medical theory is based on treating the symptoms of disease—a dynamic derisively called “bandage treatment.” This medical perspective is the inverse of homeopathic theory, which aims to treat the quantum level cause of disease. Because homeopathy addresses the quantum “first cause” of disease, it establishes precedents for understanding Divine “First Cause.” Homeopathic theory and practice are based on recognizing symptomatic syndromes—a process very similar to Carl Jung's practice of inducing healing with a patient's insight as to the meaning of dream symbolism. This meaningful insight functions like the EM signature of a homeopathic remedy. The homeopathic physician augments “remediation” of phenotypes from quantum dimensions in the same way that a Jungian psychiatrist augments (amplifies) a patient's self-healing insight. The homeopathic/Jungian dynamic works something like antibodies that neutralize antigens, so—in a virtual EM unified media-field—contextual gamers can serve the function of antibodies against mediated toxicity.

Published: January 2022

The study investigated the structure of the integrated solar and hydraulic jump enhanced waste stabilization pond (ISHJEWSP) variables. Also, to determine the cluster of the most important variables that account for the performance of the ISHJEWSP using principal component analysis (PCA). Three sets of experimental ponds were constructed with varying locations of point of initiation of hydraulic jump. Wastewater samples collected from the inlet and outlet for varying inlet velocities were examined for physicochemical and bacteriological characteristics for a period of nine months. The Pearson’s R-matrix and KMO statistic were used in evaluating the structure of the variables. Consequently, the variables of temperature, pH, algae concentration, solar radiation, and locations of the point of initiation of hydraulic jump were subjected to PCA. Two components had eigenvalues above the Jolliffe’s criterion and in combination explained 90.66% of the total variance. The inflexion of the scree plot justified the retained components. The analysis after rotation revealed that the parameters of pH, temperature, solar radiation, and algal concentration loaded highly to component 1. This underscores the precedence of ambient climatic conditions, alongside the state of the wastewater in general, to the inlet velocity and location of point of initiation of hydraulic jump.

Published: January 2022

A complete reorganization about the behavior of rectangular RC columns confined with FRP sheet is very important to predict the axial compressive strength values of the strengthened rectangular RC columns. That is because the process of strengthening RC rectangular column depending on several parameters that role this type of strengthening. These parameters include the characteristics of the used fiber, the grade of concrete and the geometry of the cross section including the rectangularity aspect ratio, corner radius, and size of specimens. Besides that, using a wide scope of experimental data may affect positively to generalize a model that considers the whole parameters affect the value of the axial strength. So, in this paper a review about parameters that affect the axial compressive strength values of rectangular RC columns was conducted. After that, based on the test results regarding FRP-confined rectangular RC columns available in the literature or conducted by the author, some existing confinement models for rectangular RC columns were assessed. Further, a new model is proposed through regression analysis of the database. A new model is proposed through regression analysis of the database. The proposed model was found to be in good agreement with the test results in the database. Finally, based on the results conclusions were drawn.

Authors: Inozemtcev Alexandr  Sergeevich , Korolev Evgenij , Qui Duong Thanh
Published: January 2022

With the development of 3D technologies in construction, the development of formulations that are indifferent to the influence of the environment is in demand. Conditions of intense water loss from cement systems arise during the layer-by-layer printing process. This leads to a decrease in density, high shrinkage, and a decrease in the strength and durability of the composite. The use of superabsorbent polymer (SAP) solutions, in contrast to granules, will provide hardening Portland cement with a water supply for internal care of hydration processes. The aim of the work is to study the effect of SAP solution on the processes of structure formation of cement stone, hardening in unfavorable conditions. In this paper, the features of the structure formation of cement systems in the presence of SAP are established. It is shown that the use of polymer in an amount of no more than 1.5% by the weight of Portland cement provides the formation of a more perfect crystalline structure of the cement stone, which allows for an increase in the degree of cement hydration. When the amount of SAP is ≥ 1.5% by the weight of Portland cement, a decrease in the intensity of the maxima corresponding to hydration products is observed.

Published: January 2022

Scientific research and the search for new technologies to increase the level of mechanical and high-temperature properties are ongoing. The article discusses the technology of using carbon materials, pyrolysis and impregnation with phenol-formaldehyde resins. It is shown that the proposed technology makes it possible to achieve a sufficient level of mechanical properties when using low-modulus carbon fabrics after pyrolytic treatment as a prepreg at a temperature treatment no higher than 900 K. Pillowcase and resole phenol-formaldehyde resins were used to impregnate the prepreg. The proposed technology also allows the introduction of alloying additives into the system to improve the properties. An example of the introduction of nitrogen into a composite by adding urotropine to a phenol-formaldehyde resin, which was used to impregnate the composite, is considered.

Published: January 2022

Purpose: The purpose of this study is two-fold. First, to examine the state of intellectual capital disclosures. Second, to investigate the relationship between board characteristics and intellectual capital disclosures. Design: This study selected thirty non-financial listed companies with the highest market capitalization from the Colombo Stock Exchange in Sri Lanka. An intellectual capital disclosure index comprising 61 items was developed to understand the level of intellectual capital disclosure in the selected companies. Panel data analysis techniques were applied to test the proposed hypotheses. Findings: Results indicated that role duality and proportion of female directors have a significant and positive impact on intellectual capital disclosures. Firm leverage was found to have a significant and negative effect on intellectual capital disclosures. Insufficient empirical evidence between other corporate board characteristics and intellectual capital disclosure in Sri Lanka may be attributed to a non-mandatory corporate disclosure environment. Originality: This is among the few studies to examine the link between corporate governance and intellectual capital disclosures employing panel data in Sri Lanka. However, a discourse on the role of corporate governance and corporate disclosures is warranted in a small island developing economy with a fragile financial system like Sri Lanka. Future Research Directions – The study calls for more studies to investigate the relationship between corporate governance and intellectual capital disclosures in the case of Sri Lanka by employing data from different industries for longer periods.

Authors: Fernando T. S. S. , Perera G. A. T. R.
Published: January 2022

The current study investigates the impact of dynamic capabilities on competitive advantage of ICT industry in Sri Lanka considering the three categories of dynamic capabilities namely adaptive capabilities, absorptive capabilities and innovative capabilities. Convenient sampling was used to draw the sample and survey data were collected from 167 ICT firms. Structural Equation Modeling (SEM) was used to analyze the relationship between variables. Finding of the study shows that dynamic capabilities have significantly positive impact on competitive advantage. In addition, the empirical evidence verifies that, innovative capabilities are more positively related to competitive advantage than other two types of dynamic capabilities while adaptive and absorptive capabilities also show the positive impact on competitive advantage.
Altered Offspring Immunity in Maternal Parasitic Infections
Authors: Gibbs Lisa C , Fairfax Keke C
Published: January 2022

Maternal infection during pregnancy is known to alter the development and function of offspring’s immune system, leading to inappropriate immune responses to common childhood infections and immunizations. Although this is an expanding field, maternal parasitic infections remain understudied. Millions of women of reproductive age are currently at risk for parasitic infection, whereas many pregnant, chronically infected women are excluded from mass drug administration due partially to a lack of resources, as well as fear of unknown adverse fetal developmental outcomes. In areas endemic for multiple parasitic infections, such as sub-Saharan Africa, there are increased rates of morbidity and mortality for various infections during early childhood in comparison with nonendemic areas. Despite evidence supporting similar immunomodulatory effects between various parasite species, there is no clear mechanistic understanding of how maternal infection reprograms offspring immunity. This brief review will compare the effects of selected maternal parasitic infections on offspring immunity.

Comparative Evaluation of Truenat Reverse Transcription-Polymerase Chain Reaction with Commercially Available Reverse Transcription-Polymerase Chain Reaction Kits for COVID-19 Diagnosis
Authors: Jaiswal Anoop , Singh Monica , Chakraborty Arindam
Published: January 2022

Introduction:

Early and correct identification of the betacoronavirus is important for effective isolation treatment and case management. Real-time polymerase chain reaction (PCR) are consider as a gold standard for the diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2); however, for that, there are a requirement of skilled workforce and elaborate infrastructure. A rapid point of care test known as Truenat Beta CoV and Truenat SARS COV assay were recommended by the Government of India. The aim of the study was to find out the performance of Truenat assay in comparison to four RT-PCR assay kits.

Materials and Methods:

The cross sectional study was conducted in a COVID-19 testing laboratory in Central India. Forty known Truenat positive sample with different viral load were analyze in selected rtPCR kits from 4 different manufacturers.

Results:

Of the total of ten very low viral load samples, BGI kit was able to detect six samples, followed by TruePCR six samples, TaqPath five samples and NIV kit were able to detect three samples. Similarly, in the case of low viral load sample, BGI and TaqPath kit were able to detect all the 10 samples followed by NIV kit five samples and TruePCR nine samples respectably. In the case of medium and high viral load samples, all four reverse transcription-PCR (RT-PCR) kits were shown a 100% detection rate.

Conclusions:

Based on our findings, we believe truenat RT-PCR is a more reliable technique for the detection of SARC-CoV-2. Hence, it should be installed in the healthcare setup for better control of the pandemic.
Knowledge, Attitude and Practice of Pediatricians Towards Digit Sucking Habit among Children in Pune, India
Authors: Shetty Samiksha Shivanand , Mathur Aditi , Khan Hania Ali , Nankar Meenakshi Y
Published: January 2022

Introduction:

Prolonged digit sucking habits can have deleterious effects on facial growth, oral function, occlusion and aesthetics, leading to dental and skeletal deformities. Early identification and intervention can result in a vast difference in treatment outcomes and avoid a complex, expensive, and time-consuming treatment in the future. Pediatricians are in a key position to identify these habits in children. The present study evaluated the knowledge, attitude and practice among pediatricians about digit sucking habits in children in Pune city, India.

Materials and Methods:

A pre-validated questionnaire was mailed to the study subjects. The filled 303 questionnaires were then statistically analyzed using descriptive statistics.

Results:

This study showed that although the number of pediatricians performing routine oral examinations was high (92.7%), the referral to dentists was low. 67.5% of pediatricians referred their patients to a dentist only when they had an explicit dental complaint. Only 20.5% of pediatricians referred children with digit sucking habits to a dentist. 95.7% of participants agreed that treatment of digit sucking is important, but only 7% of pediatricians recognized the use of habit-breaking appliances as a treatment modality.

Conclusion:

We found that although the pediatricians had sufficient knowledge regarding thumb-sucking habits in children, the involvement and collaboration with dentists was very low. The majority of pediatricians felt there was a need for more awareness programs on oral habits. We conclude that more collaborations should be encouraged between medical and dental professionals.

Published: January 2022

Hyaluronic acid fillers can be used for the correction of facial soft tissue in orthodontics patients instead of orthognathic surgery. These clinical cases show the aesthetic results of Sattler MedBeauty Seven Protocol (SMSP) in five Class II female patients after having undergone orthodontic treatment. They had the lower third of the face filled with cross-linked hyaluronic acid (e.p.t.q. S500®), according to the SMSP. All patients were evaluated before and after treatments through an inquiry on adverse events, a Numerical Visual Scale (NVS), a self-assessment questionnaire (SQ) and the analysis of photographic records (PRs). The results showed oedema, pain and haematoma as the most cited adverse events, a score of 10 in the NVS for all patients, and a good aesthetic effect of chin and mandible in SQ and PR. The results suggest that SMSP is favourable in the aesthetic correction of chin and mandible in class II orthodontic patients using e.p.t.q. S500® for compensatory filling.
