Purpose. It consists in the development of mathematical models that describe the dependence of the critical pitting temperatures of AISI 304, 08X18N10, AISI 321, 12X18N10T steels in model circulating waters with pH 4...8 and chloride concentration from 350 to 600 mg/l.
Research methods. The developed mathematical models are based on linear square regression and a neural network of direct signal propagation for a reduced set of features.
Results. It was established that the critical pitting temperatures of the studied austenitic chrome-nickel steels increase with an increase in the pH of the circulating water, the number of oxides up to 3.95 μm in size, the average distance between titanium nitrides, the Cr content and a decrease in the concentration of chlorides in the circulating water, the average distance between oxides, and the austenite average grain diameter.
Scientific novelty. Based on the established relationships between the critical pitting temperatures of corrosion-resistant steels AISI 304, 08Х18Н10, AISI 321, 12Х18Н10Т, their chemical composition within the standard and structural heterogeneity, the mechanisms of their influence on the pitting resistance of these structural materials in circulating chloride-containing waters have been developed. It was established that metastable pitting is formed in a solid solution of austenite of steels around oxides with a size of 1,98...3,95 microns and repassivates before reaching critical dimensions of about 5 microns, which contributes to the growth of their pitting resistance in reversible chloride-containing environments.
Practical value. The developed mathematical models are proposed to be used for the selection of optimal melts of austenitic chrome-nickel steels for the production of heat exchangers and prediction of their pitting resistance during their operation in circulating waters. The processes contributing to the perforation of heat transfer elements of heat exchangers during their operation have been identified.

OBJECTIVES The aim of this study is to compare the results of an Augmented Reality (AR)-based Senior Fitness Test (SFT) with those evaluated by exercise experts, in order to confirm their agreement.Methods This study was conducted on 56 frail and pre-frail elderly women who could communicate and had consented to the purpose and objectives of this study. Consistency and reliability were evaluated via the intra-class correlation coefficient (ICC) and Cronbach α between the senior fitness test results obtained using the AR-based technology and the results measured by exercise specialist. Moreover, the Bland-Altman plot was used for comparison.Results The consistency between the results obtained using the AR-based SFT system and those measured by exercise specialist is as follows: Chair Stand Test (ICC=0.877, 95%C.I.=.792-.928, Cronbach α=0.939), Arm Curl Test (ICC=0.855, 95%C.I.=.758-.914, Cronbach α=0.927), Step in Place Test (ICC=0.788, 95%C.I.=.663-.870, Cronbach α=0.879), 2.44 m Timed up and go (ICC=0.822, 95%C.I.=.715-.892, Cronbach α=0.902), Chair Sit and Reach Test (ICC=0.938, 95%C.I.=.897-.963, Cronbach α=0.968), and Back Scratch Test (ICC=0.846, 95%C. I.=.750-.907, Cronbach α=0.919). These results indicate that both evaluation methods are highly consistent.Conclusions The AR-based SFT system developed in this study is a reliable, functional evaluation method that is not affected by the skill level of the fitness test administrators. The data obtained using this system can be utilized in the future to prescribe individualized exercises for frail elderly people.

RESUMO A artroplastia de quadril (AQ) é um procedimento cirúrgico que consiste na substituição da articulação lesionada por uma prótese. O pós-operatório pode reduzir a independência funcional e repercutir na percepção subjetiva da dor em idosos. O estudo avaliou a associação entre o nível de independência funcional e a percepção subjetiva da dor em idosos submetidos à AQ. Trata-se de um estudo transversal, descritivo, quantitativo e de associação. A medida de independência funcional (MIF) foi utilizada para avaliar o nível de independência funcional, e a escala visual analógica (EVA) foi empregada para avaliar a percepção subjetiva da dor. O teste de correlação de Spearman foi utilizado para verificar a associação entre a MIF e a EVA, e uma regressão linear simples, para analisar a influência de uma variável sobre a outra (p≤0,05). Um total de 48 idosos foram avaliados, com média de idade de 71,5±9 anos, em que 37,5% (n=18) pertenciam ao sexo masculino e 62,5% (n=30) ao feminino. A avaliação da EVA mostrou uma média de 3,5 (±1,6), enquanto a MIF, 107 (±17,82). Observamos uma associação significante e inversa com p=0,006 e com r de −0,389, com R2 de 0,142. Este estudo mostrou que há uma relação inversamente proporcional entre a sensação subjetiva da dor e o nível de independência funcional de idosos no pós-operatório de AQ. A partir disso, é necessário que os profissionais da saúde deem mais atenção ao quadro álgico desses idosos, visando otimizar sua recuperação funcional a fim de aumentar sua independência funcional.

ABSTRACT This study aimed to translate, create a cut-off point, and assess the measurement properties of the female genital self-image scale (FGSIS) in Brazilian women. Content, structural, and construct validity, internal consistency, test-retest reliability, and measurement errors were assessed in this online study. FGSIS cut-off point to classify satisfaction with genital self-image (GSI) was performed using the Partial Credit Model (PCM). In total, 614 women (28.92±9.80 years) participated in the study. The FGSIS had a one-factor structure and adequate measurement properties. FGSIS≥22 points classify women as satisfied with their GSI. Therefore, FGSIS is a simple, valid, and reliable measure to assess GSI in Brazilian women.

Authors: Paula Julia Paixão de , Navega Marcelo Tavella , Spinoso Deborah Hebling
Published: April 2023

RESUMO A dor patelofemoral (DPF) pode contribuir para menor ativação do músculo quadríceps, favorecendo maior sobrecarga e dor nesta articulação. A eficiência neuromuscular (ENM) é uma variável que avalia a relação entre a quantidade de estímulos neurais e a capacidade de geração de força de um determinado músculo, sendo mais eficiente aquele que produz maior força muscular, com menor ativação das fibras musculares. Nesse sentido, o objetivo do estudo foi avaliar a força e a ENM dos extensores de joelho em mulheres com e sem dor patelofemoral. Participaram deste estudo 24 mulheres, recrutadas por meio de um questionário, com idades entre 18 e 30 anos, com e sem dor patelofemoral. Foram realizadas a anamnese, a escala de dor anterior no joelho e a escala visual numérica e, posteriormente, a avaliação da força extensora de joelho, com dinamômetro manual, e a avaliação da ENM de vasto medial (VM), vasto lateral (VL) e reto femoral (RF). Para análise estatística, foram adotados os testes apropriados para comparação das variáveis entre os grupos e para correlação entre elas. Em todos os testes estatísticos foi adotado o nível de significância de α<0,05. Os resultados mostraram que mulheres com DPF apresentaram 61% menor ENM do VM e 52% do VL, em comparação ao grupo sem dor. Não se encontrou diferença significativa para força extensora de joelho entre os grupos. Concluímos que a dor influencia negativamente o recrutamento de VM e VL, mas não altera a capacidade do quadríceps de gerar força.
A endemia de tracoma em São Paulo no início do século XX: as atuações governamentais e as repercussões na comunidade internacional
Authors: Gois Soraya Lodola de Moraes
Published: April 2023

RESUMO O tracoma, uma enfermidade oftálmica com alto risco de cegueira, tornou-se endêmica no final do século XIX em vários países da Europa, Ásia, África e América. No Brasil, a doença foi mais intensa nos estados com forte política imigratória, em especial em São Paulo, atingindo principalmente a população rural. Este artigo objetiva analisar como a disseminação do tracoma no início do século XX em São Paulo criou fissuras nas relações internacionais e como as pressões dos países vinculados às políticas imigratórias poderiam ter influenciado nas medidas profiláticas implantadas. A pesquisa relevou que as atuações governamentais de combate ao tracoma, realizadas de forma intermitente, coincidiram com os períodos de dissensos com a Itália, Espanha e Argentina, demonstrando que as questões migratórias estavam fortemente alicerceadas entre os fatores que definiram a política sanitária do período.

Abstract: The cottonseed delinting removes lint from the seed coat to improve plantability and maintain the seed’s physiological quality, therefore, this work aimed to determine the effect of delinting and neutralizers’ residual on the physiological quality of stored cottonseed by using image analysis phenotyping. The experiment was a randomized factorial design of 3 x 4 x 2 and two periods of storage evaluation (0 and 180 days). The cotton seeds were delinted at three different times (2, 4, and 10 minutes), neutralized using four distinct neutralizers (Quicklime, Hydrated lime, Filler lime, and NaOH), and there were seeds with and without neutralizer residue. The evaluations carried out were: water content, seed residual lint imaging, germination, seedling emergence, and seedling length imaging. The neutralizers Quicklime, Hydrated lime, and Filler lime do not need removal from the cotton seed coat. In storage, only the neutralizer NaOH has a high latent effect in lowering cottonseed quality, and the other neutralizers have lower physiological quality when the residue is removed. The image analysis phenotyping is efficient in identifying seedlings’ vigor.

Abstract: Seed treatment is important for protecting seed and seedling from pests and/or pathogens. Seed treatment can be performed generally in two ways: industrial seed treatment (IST), performed by seed companies, or on-farm treatment (OFT). These treatment technologies will affect the final quality of the process. Therefore, the objective of this study was to characterize the seed quality profile of ISTs and OFTs in Brazilian agribusiness in terms of functional quality and dose application effectiveness (DAE). Seed samples treated by both processes were collected in 6 producing states of Brazil, Mato Grosso, Goiás, Paraná, Minas Gerais, São Paulo, and Santa Catarina. To evaluate the functional quality of the treatments, the coating percentage was determined by high-resolution image analysis with GroundEye® equipment, and the insecticide active ingredient DAE amount was determined with high-performance liquid chromatography (HPLC). Image analysis proved to be a promising technique to evaluate seed coating, in addition, samples treated with “on farm” technology had greater variation and heterogeneity in coating and active ingredient dose, while samples treated industrially showed greater homogeneity, uniformity, effectiveness of applied products. There was a strong positive correlation between coating with phytosanitary products and DAE in treated corn seeds, important parameters in the evaluation of the quality of the treatment.

Published: April 2023

The main issue associated with the disposal of old tires is that they contain harmful chemicals and heavy metals that can contaminate the environment as they break down. One solution to this problem is the use of a process known as pyrolysis, which breaks down the tires and produces useful by-products. This process results in the formation of gas, liquid, and solid phases, with the gas containing tar
and other components. In this study, we employed a method known as solid-phase adsorption to determine the concentration of tar compounds. A specific sampling device using an amino-phase sorbent and activated coconut charcoal was found to be effective in collecting the tar and its volatile organic compounds from the gas produced during tire pyrolysis. The study was conducted using a rotary kiln
pyrolysis reactor in Latvia. The amount of tar was measured by drawing varying volumes of pyrolytic gas through the adsorbents and comparing it to the amounts of individual component compounds.

Published: April 2023

Magnesium oxysulfate cement has low strength and poor water resistance, so an additive is essential for the preparation of basic magnesium sulfate cement (BMSC). In this paper, the effects and the mechanisms of three organic weak acids on the water resistance in relation to flexural strength of BMSC are investigated. The results show that malic acid fails to ameliorate the water resistance in relation to flexural strength, but citric acid and tartaric acid are successful. The ionisation constant and molecular formulas of different weak organic acids can affect the performance, such as fluidity, strength and water resistance. Therefore, the effect of citric acid is better than tartaric acid, and the optimal dosage of citric acid is 1.0%.

Published: April 2023

A habilidade gerencial advém das capacidades, competências e experiências que refletem em diferenciais estratégicos para todos os níveis organizacionais, sendo uma premissa de maior eficiência e conhecimentos contábeis e tributários que podem trazer grandes benefícios no resultado das organizações. Neste contexto, este estudo busca verificar a influência da habilidade gerencial na conformidade contábil-fiscal das empresas de capital aberto em nível global. Esta pesquisa caracteriza-se como descritiva, com abordagem quantitativa, realizada por meio de coleta documental e os dados foram tratados pela regressão linear múltipla. A população da pesquisa compreende as companhias abertas de 28 países, sendo a amostra composta de 11.506 companhias no período de 2012 a 2019. De maneira geral, os resultados comprovaram que a habilidade gerencial influencia positivamente o nível de conformidade contábil-fiscal das empresas. Ao comparar os resultados entre os grupos de países analisados, evidencia-se que a orientação legal do país se torna um fator complementar à habilidade gerencial na determinação da conformidade contábil-fiscal. Por exemplo, as empresas com gestores mais habilidosos localizadas em países common law apresentam maior desconformidade contábil-fiscal, por outro lado, as empresas com maior habilidade gerencial de países civil law e muçulmanos apresentam maior conformidade contábil-fiscal. O estudo reforça a premissa de que as empresas de países common law e com maior habilidade gerencial estão preocupadas com a informação contábil de maior qualidade aos usuários externos, dando menos ênfase no uso da contabilidade societária para apuração tributária.
The Everyday Wonders of Science

Published: April 2023

Rural communities are oftentimes neglected when it comes to science communication. This leaves individuals feeling excluded, negatively impacting their relationship with science. The aim of this project is to get more people, especially those in rural communities, to engage with science. For this project, I have created a podcast mini-series highlighting the ways that science impacts our daily lives. This podcast series discusses the scientific method with Dr. Bryan Phillips of the University of Iowa in the episode titled Why the Scientific Method Isn’t Just for Scientists. Water quality is also discussed in the podcast in the episode titled The Importance of Improving Water Quality with Dr. David Cwiertny of the University of Iowa.In order to cater this podcast to rural communities, I have partnered with various public libraries across the state of Iowa to establish content areas of interest and ways to reach their patrons. The podcasts consist of interviews with professionals and faculty at the University of Iowa that have extensive experience in the areas of interest. These short episodes are intended to be easily digestible in order to get people excited about science and how it works without us even knowing.

Published: April 2023

Background: Cesarean section under spinal anesthesia may cause anxiety and hypotension. Administration of sedative drugs after delivery can diminish these side-effects, but may increase hemodynamic instability. We evaluated the effect of the administration of 0.7 μg/kg dexmedetomidine and compared it with that of 0.03 mg/kg midazolam for usefulness of sedation of the parturient after delivery during cesarean section.Methods: After obtaining written consent and the ethics board approval, 60 parturients aged 20–43 years who underwent elective cesarean delivery under spinal anesthesia were recruited. A total of 0.5% hyperbaric bupivacaine (8–10 mg) and intrathecal fentanyl (10 μg) was given to induce anesthesia. Parturients were then randomly allocated to receive either midazolam (0.03 mg/kg; group M) or dexmedetomidine 0.7 (μg/kg; group D) after delivery. The primary outcome measure was patient satisfaction score. Secondary outcomes included vital signs; vasopressor dosage; incidence of shivering, nausea, and vomiting; incidence of bradycardia; time to sensory and motor recovery; postoperative nausea and vomiting score; and postoperative pain visual analog scale at 6, 24, and 48 h.Results: Satisfaction scores for sedation were similar between the two groups. The systolic blood pressure, heart rate, oximetry saturation, and tympanic temperature were comparable between the two groups. The predicted mean systolic blood pressure of group D was 106.3 mmHg and that of group M was 107.5 mmHg. Both groups showed comparable adverse intraoperative and postoperative outcomes.Conclusions: Dexmedetomidine and midazolam showed similar hemodynamic effects and patient satisfaction in parturients under spinal anesthesia.
Management of unanticipated difficult airway in a patient with well-visualized vocal cords using video laryngoscopy
- A case report -
Authors: Ki Seunghee , Cho Seung Bae , Park Seongmin , Lee Jeonghan
Published: April 2023

Background: Difficult airway occurs due to anatomical abnormalities of the airway that can be predicted through airway assessments; however, abnormalities beyond the vocal cord can be clinically asymptomatic and undetected until intubation failure to advance the endotracheal tube.Case: We present a case of an unanticipated difficult airway in a stuporous 80-year-old female with a recent history of intracerebral hemorrhage and prolonged intubation. She required emergency ventriculo-peritoneal shunt surgery due to the progression of her hydrocephalus. Under anesthesia, facemask ventilation was easy and video laryngoscopy provided a full view of the glottis; however, endotracheal tube (ETT) entry failed. We suspected stenosis beyond the vocal cord, and a smaller diameter ETT was inserted and maintained for airway management during emergency surgery. Postoperative neck computed tomography findings revealed laryngotracheal stenosis (LTS).Conclusions: Anesthesiologists should be aware that LTS may be asymptomatic and consider difficult airway guidelines in patients with history of prolonged endotracheal intubation.
Current concerns on journal article with preprint: Anesthesia and Pain Medicine perspectives
Authors: Kang Hyun , Oh Hyoung-Chul
Published: April 2023

Preprints are preliminary research reports that have not yet been peer-reviewed. They have been widely adopted to promote the timely dissemination of research across many scientific fields. In August 1991, Paul Ginsparg launched an electronic bulletin board intended to serve a few hundred colleagues working in a subfield of theoretical high-energy physics, thus launching arXiv, the first and largest preprint platform. Additional preprint servers have since been implemented in different academic fields, such as BioRxiv (2013, Biology; www.biorxiv.org) and medRxiv (2019, Health Science; www.medrxiv.org). While preprint availability has made valuable research resources accessible to the general public, thus bridging the gap between academic and non-academic audiences, it has also facilitated the spread of unsupported conclusions through various media channels. Issues surrounding the preprint policies of a journal must be addressed, ultimately, by editors and include the acceptance of preprint manuscripts, allowing the citation of preprints, maintaining a double-blind peer review process, changes to the preprint’s content and authors’ list, scoop priorities, commenting on preprints, and preventing the influence of social media. Editors must be able to deal with these issues adequately, to maintain the scientific integrity of their journal. In this review, the history, current status, and strengths and weaknesses of preprints as well as ongoing concerns regarding journal articles with preprints are discussed. An optimal approach to preprints is suggested for editorial board members, authors, and researchers.
What we need to know and do on sugammadex usage in pregnant and lactating women and those on hormonal contraceptives
Authors: Do Wangseok , Cho Ah-Reum
Published: April 2023

Sugammadex is a chemically modified γ-cyclodextrin that is used as a selective reversal agent for steroidal neuromuscular blockade. The use of sugammadex has greatly increased globally; however, little is known about its potential adverse effects in pregnant and lactating women or those using hormonal contraceptives. There are three important theoretical assumptions. Firstly, pregnancy-related physiological changes involve most organs and affect the pharmacokinetic profiles of medications. Considering the physiological changes in pregnant women and the pharmacokinetic properties of sugammadex, alterations in the dosage and safety profiles of sugammadex may occur during pregnancy. Secondly, very large and polarized sugammadex molecules are expected to have limited placental transfer to the fetus and excretion into breast milk. Finally, sugammadex can bind to steroidal neuromuscular blocking agents as well as other substances with similar structures, such as progesterone. As a result of using sugammadex, progesterone levels can be reduced, causing adverse effects such as early pregnancy cessation and failure of hormonal contraceptives. This narrative review aims to demonstrate the correlations between sugammadex and pregnancy, lactation, and reproductive potential based on previously published preclinical and clinical studies. This will bridge the gap between theoretical assumptions and currently unknown clinical facts. Moreover, this review highlights what anesthesia providers should be aware of and what actions to take while administering sugammadex to such patients.

Egzersiz bağımlılığı spor bilimleri alanında çeşitli konular yönüyle ele alınmaktadır. Bu araştırmanın amacı iki takım sporu olan futbol ve basketbol sporcularının egzersiz bağımlılık düzeylerini incelemektir. Araştırmada kişisel bilgi formu ve Egzersiz Bağımlılığı Ölçeği kullanılmıştır. Çalışmaya dâhil edilen sporcular, futbol kadın (n=30) ve erkek (n=40) ile basketbol kadın (n=30) ve erkek (n=40) katılımcılardan oluşmaktadır. Cinsiyet değişkeninden bağımsız yapılan karşılaştırmada futbolcuların basketbolculardan daha yüksek olarak bağımlılık skoruna sahip oldukları ve her iki grubunda bağımlı grupta yer aldıkları belirlenmiştir. Ayrıca erkeklerin kadınlara oranla daha yüksek bağımlılık sergiledikleri tespit edilmiştir. Sonuç olarak; bu çalışmada, egzersiz bağımlılığının dayanıklılığın baskın olduğu futbol ve basketbol branşlarında önemli bir risk faktörü olduğu saptanmıştır. Yoğun antrenman gerektiren, uzun yüklenmelerin ve yoğun müsabaka dönemlerinin de sporcuların egzersize karşı olan tutumlarında farklılıklar yaratabileceği ifade edilmiştir. Literatürden hareketle, cinsiyet farklılıklarının egzersiz bağımlılığını etkileyebileceği sonucuna varılmıştır. Egzersiz bağımlılığı, sporcular için göz ardı edilmemesi gereken önemli bir risk faktörü olarak görülmektedir. Bu yüzden sporcular egzersiz bağımlılığı konusunda bilgilendirilmeli ve antrenörleri tarafından da takip edilmelidirler.

This Special Section explores questions of method and positionality attached to moral agency in mental healthcare, which give rise to novel methodological and theoretical approaches to everyday life in the clinical and non-clinical spaces where such ‘care’ occurs. Moral agency is the ability to be perceived as a ‘good enough’ person, which makes possible intimate relationships with others that are needed to thrive in many social contexts (Myers 2015). In this introduction, we draw on Mattingly’s (2014) notion of everyday moral laboratories: an exploratory attention to moral life as innovative method, episteme, and interpersonal collaboration. Exploring the everyday moral laboratories where people struggle to replenish or protect their moral agency and so create meaning and relationships in their lives is a key focus of this Special Section. For interdisciplinary ethnographers working in spaces intended for care, such experimentation yields opportunities to more creatively and proactively inform that care—the everyday, the ordinary, and the extraordinary—that centres on helping our interlocutors replenish moral agency and thrive.

Access to clean water, one of the United Nation’s Sustainable Development Goals, is challenged by an increase in the presence of emerging microbial and other contaminants due to urbanization, among other factors. Traditionally, the presence of indicator microorganisms is determined using culturing methods. However, these classical methods cannot be used to determine the identities of ‘unknown’ bacteria and is limited to isolating the culturable state of microorganisms. Thus with culturing, the identities of many bacteria, particularly novel or non-culturable, may remain unknown. The use of a DNA-based method, 16S rRNA next-generation sequencing (NGS), can assist with determining the identities of bacterial populations in a water sample. The objective of this 16S rRNA NGS study was to investigate the bacterial community composition and diversity in a range of water sources. Water samples comprising of potable, surface, ground, marine, aquaculture, rain, wetland and swimming bath water matrices were subjected to 16S rRNA NGS using the Illumina 16S rRNA Metagenomics analysis pipeline. Operational taxonomic units were analysed and the identities of bacterial genera determined. In this study, genera of Acinetobacter, Mycobacterium, Pseudomonas, Legionella, Burkholderia, Yersinia, Staphylococcus and Vibrio were spread across the water matrices. Alpha (within sample) and beta (between samples) diversities for each bacterial community within the tested samples were also determined.

This study was conducted to determine the effect on growth performance and intestinal histomorphology of the rainbow trout (Oncorhynchus mykiss) fed diets including black soldier fly (Hermetia illucens) prepupae meal (HI) and mealworm (Tenebrio molitor) larvae meal (TM) used instead of fish meal. Six diets with HI and TM at three inclusion levels (10%, 20% and 30%) and a control diet based on fish meal were prepared. Test diets were encoded as control, HI10, HI20, HI30, TM10, TM20 and TM30. Fish (average initial weight of 34.17±0.88 g) were randomly placed (30 for each) in 500 L fibreglass tanks. Each of the seven diet treatments was tested in triplicated tanks. Fish were fed by hand at a level of 2.5% of body weight three times a day for 90 days. Results demonstrated that the growth performance and intestinal histomorphology were significantly affected by black soldier fly (HI) prepupae meal substitution (p<0.05). HI prepupae meal used instead of the fish meal had a negative effect on the growth performance, but not on the intestinal villi length. In addition, intestinal villi width decreased in fish on diets containing 10% or 20% HI prepupae meal. The growth performance and intestinal histomorphology were significantly affected by diets including TM. The diets containing 20% and 30% TM meal significantly decreased growth performance variables, but intestinal villi length increased. The results suggest that mealworm meal (10%) can be included in diets of rainbow trout at a level of 10% instead of fish meal without adversely affecting growth performance. Future studies should be expanded using a highly defatted TM and HI larvae meals.

The purpose of the study was to develop an optimal model of the stage of direct preparation for competitions of highly qualified multieventers in athletics and experimentally justify its effectiveness.
Materials and methods. 5 highly qualified multieventers, whose sports qualification is the Master of Sports of Ukraine, participated in the pedagogical experiment. The average age of the participants was (M±SD) 25.2±1.79 years. Research methods: theoretical analysis and generalization of data from literary sources; pedagogical experiment (the study was conducted from 2019 to 2021 according to the scheme of a sequential pedagogical experiment: from 2019 to 2020 - the ascertaining stage and from 2020 to 2021 - the formative stage); pedagogical observation of training and competitive activities; pedagogical testing (running 60 m from a high start, running 2 x 200 m with a rest interval of 1 min, triple jump from a standing position, throwing a ball with two hands from below on range, the running version of the PWC170(V) test was used for estimation of physical capacity and aerobic productivity of athletes); mathematical and statistical methods.
Results. The total amount of training work of the studied multieventers at the stage of the formative experiment was reduced to 3148 min, compared to the ascertainment stage (4999 min), however, their intensity increased to an average of 6.11 points/min, compared to 5.72 points/min at the ascertainment stage. We managed to optimize the training process due to the developed models of microcycles at the stage of direct preparation for competitions, in which attention was focused on the leading types of each of the multieventers.
Conclusions. Reducing the amount of load at the stage of direct preparation for competitions with a simultaneous increase in their intensity allowed the athletes to reach the peak of their sports form, as evidenced by the results of the main competitions of each of the athletes. The analysis of indicators of physical and functional fitness of highly qualified track and field athletes made it possible to establish that most of the results at the stage of the formative experiment improved statistically in a reliable way by an average of 2.6-6.5 %, which confirms the effectiveness of the proposed 8-week model of the stage of direct preparation for the competition and allows to recommend it for practical use in the training process of multieventers at the stage of maximum fulfillment of individual capabilities.

Study purpose. This study aimed to determine the impact of school Physical Education programs on well-being and cognitive ability (CA), as measured by mathematics achievements, in primary school children.
Materials and methods. The study participants selected from three schools were 100 girls and 102 boys aged 9–10 years. According to Kliziene et al. (2022), the CA diagnostic test for mathematics in Grade 4 is grounded in Feuerstein and Lewin-Benham’s (2012) dynamic cognitive modality assessment theory, as well as the General Curriculum for Primary Education approved by the Minister of Education and Science of Lithuania (ISAK-2433, 2008). This test designed for learners in Grade 4 encompasses mathematics. The study aimed to assess the level of enthusiastic well-being by examining three primary dimensions: somatic anxiety, personal anxiety, and social anxiety. To measure anxiety, the Revised Children’s Manifest Anxiety Scale (RCMAS) was used, which consists of 37 items, with 28 of them assessing anxiety and the other 9 measuring the child’s defensiveness. In this study, a pre-/post-test experimental methodology was used to avoid any interruption of educational activities, due to the random selection of children in each group. The methodology depended on dynamic exercise, intense repetition of motor skills, differentiation, seating and parking reduction and physical activity distribution in the classroom model.
Results. The CA diagnostic test was analyzed in terms of the learners’ levels of achievement (satisfactory, basic, advanced) and cognitive functions. The systematic exploration function was used to achieve systematic, non-impulsive, planned behavior when collecting data or checking information. There was a strong difference between students at the satisfactory and advanced levels in the ability to orient themselves in space and follow directions (score for boys, Post-test 2.53 (0.25) points; for girls, Post-test 2.91 (0.32) points out of a maximum 4 points; p<0.05). After the school PE program, the personality anxiety results decreased for both boys (2.68 ± 0.98 points) and girls (3.41 ± 0.55 points) (F = 4.98, p < 0.05, P = 0.729).
Conclusions. Overall, the physical education program implemented in this study was found to have a positive effect on the psychological well-being of 9–10-year-old children, specifically in reducing somatic anxiety, personality anxiety, and social anxiety. Additionally, it was observed that the program led to statistically significant improvements in the children’s cognitive abilities across nine functions, including spatial orientation, sequencing, recognition of relationships and patterns, and information processing.

A multicenter, open label, non-comparative, 3 months study to assess the performance and safety of the new medical device Polybactum® in reducing the frequency of Recurrent Bacterial Vaginosis v1
Authors: Murina Filippo
Published: April 2023

Medical literature has evidenced in recurrent bacterial vaginosis a relapse rate of 35% within 3 months and 60% within 12 months after antibiotic administration. The products able to create a barrier effect against the biofilm produced by Gardnerella vaginalis could play a role in improving the results of bacterial vaginosis treatment. This research project (composed by a main study plus a follow-up study) aimed to test the performance and the safety of a medical device containing polycarbophil, lauryl glucoside, and glycerides (PLGG) in reducing the rate of recurrence of BV. The project included two phases: in the first one (according to an open-label, non-controlled design) the treatment with PLGG was administered for three cycles and it was followed by a 1-month of follow-up without treatment. In the second phase of the study a 9-month follow-up period was envisaged. This entailed that, for each patient, a 10-months follow-up period without treatment was planned. Bacterial vaginosis diagnosis was performed using Amsel criteria. The 55 planned patients were enrolled in five centres (two in Italy and three in România).
