Published: February 2024

Background::

The present work was conducted to investigate the quality and antioxidant properties of some Algerian extra virgin olive oils (EVOOs).

Objective::

In this paper, the physicochemical characteristics and antioxidant properties of four
EVOOs of monovarietal samples (Chemlal) from East Algeria were studied.

Methods::

Physicochemical characteristics, which include free acidity, peroxide index, saponification index, specific extinction coefficients, water content, refractive index, relative density,
and chemical composition, in addition to their antioxidant activity, were investigated based on
DPPH free radical-scavenging activity (DPPH-SA).

Results::

The results of physicochemical and quality parameters proved that all samples are
EVOOs with highly nutritious and health benefits for the consumer, as per the recommendation
of the International Olive Council (IOC). The results showed that the olive oils from the southern arid region of Algeria (Sahara), have a high antioxidant activity than the samples from the
Northern regions.

Conclusion::

These findings revealed a significant influence of geographic location on the
chemical characteristics and antioxidant activities of olive oil from the same cultivar (Chemlal). These olive oils from the arid Saharan region may be used as a functional food with great
antioxidant potential.

Authors: McKinnon Luke S. , Symes Michael J. , Wines Andrew , Mittal Rajat
Published: February 2024

Introduction

Joint fusion is a widely accepted treatment option for debilitating arthritis and deformity in the foot and ankle. Autologous bone grafting has long been accepted as the gold standard form of bone grafting; however, it can still be associated with non-union. This study aims to investigate joint fusion rates using Composite Peptide Enhanced Bone Graft (CPEBG) as an adjunct during ankle fusion surgery.

Methods

Data was collected retrospectively for patients over the age of 18 years, undergoing ankle fusion between June 2016 and August 2020 with autologous bone graft and CPEBG. All patients had their primary or secondary procedure performed by a single surgeon with follow-up at 6 and 12 months post-operatively. Data included baseline demographic data and procedural characteristics. The primary endpoint was to assess joint union at 6 and 12 months, respectively. Secondary objectives included post-operative pain, mobility and the use of walking aids.

Results

Radiographic union rates for the primary group were 40/48 (83%) and 43/48 (90%) at 6 and 12 months and 2/3 (67%) and 3/3 (100%) at 6 and 12 months for the secondary group, respectively. The overall non-union rate for primary ankle fusions was 8%, while no non-unions were observed in the secondary group.

Conclusion

CPEBG in foot and ankle fusion procedures yields similar union rates compared to other graft options. Further well-designed randomised control trials are warranted to confirm these findings.

Authors: Neamah Wurood Hantoosh , Hasan Fatimah Ali , Jasim Fatimah Mahdi , Hachim Aqila Jumaah
Published: February 2024

Background

Weed infestation and salinity are both biotic and abiotic stresses that are highly present in the Basrah governorate in Iraq and widely influence crop growth

Methods

The present work was conducted to evaluate the effect of salinity at (0, 6, 12 dS/m) and aqueous extract of Alhagi maurorum at (0, 3 g/L) on growth and biochemical parameters as well as phytocomponents of Dill plant Anethum graveolens L.

Results

Results revealed that growth parameters and photopigment content increased with salinity at 12 dS/m and reduced with Alhagi maurorum aqueous extract. Besides that, carbohydrate content was reduced with both stresses, and proline content increased with Alhagi maurorum aqueous extract. GC-MS chromatogram of Anethum graveolens methanolic extract displayed high alteration in phytocomponents quantity post salinity and camelthorn extract treatments.

Conclusion

Current work inferred that the Dill plant has high tolerance properties to salinity contrary to weed infestation stress. Stresses combination declined growth parameters and reduced metabolite content of Dill plants.

Authors: Tanaporn Phankam , Sarunya Benjakul , Mondha Kengganpanich
Published: February 2024

Background

Despite the nationwide enforcement strategies in place to prevent road accidents, including wearing a helmet, not riding a motorcycle while drunk, using a safe motorcycle, obtaining a motorcycle license and avoiding speeding, accidents still occur, particularly among young motorcyclists.

Objectives

The study aimed to describe the level of behaviors and factors affecting safe motorcyclists' riding behaviors.

Methods

The cross-sectional study with single-stage cluster sampling was conducted to select 326 students in years 1–4 of the 1st semester of every faculty at Phranakhon Si Ayutthaya Rajabhat University. Data were collected using online self-administered questionnaires from December 2022 to January 2023. Descriptive and inferential statistics, including the Chi-square test, Pearson correlation coefficient and Stepwise multiple regression analysis, were used to analyze the data.

Results

Most respondents had safe motorcyclist riding behaviors at a safe level (54.6%), good knowledge-related traffic rules (41.1%), a positive attitude towards behaviors (67.8%) and a high level of support from influencing groups as subjective norms on behaviors including family members (69.6%), friends (58.3%) and favorite celebrities who participated in a road safety campaign (48.4%). Most had high perceived behavioral control (53.1%) and behavioral intention (64.7%). Eight factors were significantly associated with safe motorcyclist riding behaviors: student’s year, having a motorcycle driving license, driving a motorcycle after alcohol drinking, attitude towards behaviors, subjective norms concerning behaviors, perceived behavioral control, and behavioral intention. Based on the results, four factors could significantly predict safe motorcyclist riding behaviors up to 45.6% (Nagelkerke R2 = 0.456, p <0.001) composed of perceived behavioral control, having a motorcycle driving license, behavioral intention and subjective norm influenced by friends.

Conclusion

The study could provide valuable input for institutional administrators and related organizations to formulate policies promoting safe riding behaviors among motorcyclist students. Additionally, these results may be beneficial in organizing awareness-raising campaigns to prevent motorcycle-related accidents and monitor the process of acquiring a motorcycle driving license.

Authors: Chen Mingliang , Xie Guoqiang , YU Yingting , Zeng Chuanhan , Xu Zaide , Li Yuan , Li Yuancheng
Published: February 2024

Background:

Compared with the traditional power system, the large-scale access of
distributed energy resources in the new power system has a great impact on the structure and operation
mode of the power grid, and it is also more susceptible to device-level and network-level
FDI attacks.

Objective:

In order to improve the accuracy and precision of detecting false data injection attacks
in distributed energy resources integration into distribution networks and to further explore time
series modeling methods for measurement data, it is helpful for the FDIAs detection method to be
widely adopted and applied in new power systems.

Method:

To address false data injection attacks on distributed energy resource integration into
distribution grids within new power systems, a data-driven time series anomaly detection method
is employed. Firstly, time-aware shapelets are extracted from time series data, and then the shapelet
evolution graph is constructed to capture the correlation between the shapelets. Finally, time
series representation vectors are learned using segment embeddings derived from the shapelet
evolution graph through the DeepWalk algorithm. These representation vectors are then input into
a BO-XGBoost anomaly detector, facilitating the detection of FDIAs.

Results:

After multiple rounds of parameter tuning, the parameters of Shapelet quantity (K=40)
and segment length (L=4) achieved an accuracy of 92.8% in FDIA detection. Comparative experimental
results with different algorithms indicate that, compared to other unsupervised learning
methods, this approach exhibits an accuracy improvement of 20-40%. In the case of BOXGBOOST,
it achieves a 5% increase in accuracy compared to the unmodified XGBOOST.

Conclusion:

The experimental results indicate that this method can effectively detect false data
injection attacks on the integration of distributed energy resources into distribution grids within
new power systems. This model significantly enhances detection accuracy and precision while
also imparting physical significance to the dynamic evolution of time series models.
Narrative Literature on Breastfeeding Counseling during COVID-19: A South African Case of Primary Healthcare
Authors: Mphasha Mabitsela Hezekiel
Published: February 2024

Background

Infant and young child feeding (IYCF) is vital to improve child survival and promote healthy growth and development. However, during the coronavirus-19 (COVID-19) pandemic, access to healthcare facilities or IYCF educational campaigns was limited since the focus was on managing the pandemic. Skin-to-skin contact between mother and child is the core of IYCF guidelines, yet COVID-19 regulations encourage social distancing and separation. The aim of this review was to describe challenges and lessons drawn during the COVID-19 pandemic in the delivery or promotion of IYCF.

Methods

This is a narrative literature review, which does not require seeking any ethical approvals. Publications related to the stated key search items, written in English, were included in this review study. Data was sourced from various sources, such as Scopus/Elsevier, ScienceDirect, and PubMed databases, as well as World Health Organization and United Nations Children's Funds. Search items used included IYCF promotion and services during COVID-19.

Results

A total of 43 publications were included in this review. Findings of the literature showed that there were fears of mother-to-child transmission of COVID-19 and poor feeding practices. The use of IYCF services was also limited.

Conclusion

For future COVID-19 waves and similar pandemics, the social distancing and separation of mother to child should not occur since there is minimal risk of transmission of COVID. Therefore, skin-to-skin contact and overall breastfeeding should be promoted. The IYCF guidelines should be reviewed to focus on personal hygiene practices, such as routine soap use and disinfecting of food preparation areas.

Authors: Willinger Laura , Böhm Birgit , Schweizer Florian , Reimer Lara Marie , Jonas Stephan , Scheller Daniel A , Oberhoffer-Fritz Renate , Müller Jan
Published: February 2024

Background

The prevalence of physical inactivity among children and adolescents is alarmingly high despite the well-documented and comprehensive benefits of regular physical activity (PA). Therefore, PA promotion should start early in childhood and adolescence. Although reducing recreational screen time in children and adolescents is an urgent concern, digital approaches have the potential to make activity promotion attractive and age appropriate for the target group. KIJANI is a mobile app approach to promote PA in children and adolescents via gamification and augmented reality.

Objective

This study protocol aims to describe the KIJANI intervention in detail, as well as the evaluation approach.

Methods

KIJANI is based on the concept that virtual coins can be earned through PA, for example, in the form of a collected step count. With these coins, in turn, blocks can be bought, which can be used to create virtual buildings and integrate them into the player’s real-world environment via augmented reality. PA of users is detected via accelerometers integrated into the smartphones. KIJANI can be played at predefined play locations that were comprehensively identified as safe, child-friendly, and attractive for PA by the target group in a partner project. The evaluation process will be divided into 2 different stages. The phase-I evaluation will be a mixed methods approach with one-on-one semistructured interviews and questionnaires to evaluate the user experience and receive feedback from the target group. After the implementation of results and feedback from the target group, the phase-II evaluation will proceed in the form of a 2-arm randomized controlled trial, in which the effectiveness of KIJANI will be assessed via objectively measured PA as well as questionnaires.

Results

The study received ethical approval from the ethical board of the Technical University of Munich. Participants for the phase-I evaluation are currently being recruited.

Conclusions

The study will help to determine the efficacy, applicability, and user experience of a gamified activity promotion application in children and adolescents. Overall, digital health approaches provide easy and wide reachability at low cost and are age appropriate and attractive for the target group of adolescents. Strategies have to be developed to apply digital health approaches in the best possible way for activity promotion.

Authors: Bunnell Brian E , Schuler Kaitlyn R , Ivanova Julia , Flynn Lea , Barrera Janelle F , Niazi Jasmine , Turner Dylan , Welch Brandon M
Published: February 2024

BACKGROUND

Homework is implemented with variable effectiveness in real-world therapy settings, indicating a need for innovative solutions to homework challenges. We developed Adhere.ly, a user-friendly, Health Insurance Portability and Accountability Act–compliant web-based platform to help therapists implement homework with youth clients and their caregivers. The initial version had limited functionality, was designed for youth clients and their caregivers, and required expanding available features and exercises to suit adult clients.

OBJECTIVE

The purpose of this study was to better understand barriers and potential solutions to homework implementation experienced by therapists seeing adult clients and obtain their input on new features and exercises that would enable Adhere.ly to better meet their needs when working with this population.

METHODS

This study used an exploratory, sequential mixed methods design that included 13 semistructured focus groups with mental health therapists and clinic leaders and a survey administered to 100 therapists. Analyses were performed using the NVivo qualitative analysis software and SPSS.

RESULTS

The findings revealed common barriers, such as clients and therapists being busy, forgetting to complete homework, managing multiple platforms and homework materials, and clients lacking motivation. Adhere.ly was perceived as a potential solution, particularly its user-friendly interface and SMS text-message based reminders. Therapists suggested integrating Adhere.ly with telemedicine and electronic health record platforms and adding more exercises to support manualized therapy protocols and therapy guides.

CONCLUSIONS

This study highlights the importance of technology-based solutions in addressing barriers to homework implementation in mental health treatment with adult clients. Adhere.ly shows promise in addressing these challenges and has the potential to improve therapy efficiency and homework completion rates. The input from therapists informed the development of Adhere.ly, guiding the expansion of features and exercises to better meet the needs of therapists working with adult clients.
College Virtual Tour using Virtual Reality

Published: February 2024

Abstract: Virtual reality has become one of the highly interesting and popular fields. Also in recent times, the concept of the metaverse and its idea of a virtual world is being spread rapidly. As the technological connotation of the term VR has been changing and encompasses various VR systems with different capabilities, it has also paved a way for virtual tourism. The current pandemic situation made people around the world stay inside their houses, which has led to the growth of virtual tourism. Yet the usage of VR is not as wide as its reach. The main reason for VR’s less usage is its affordability, not everyone could afford a VR headset. The objective of this project is to create an immersive virtual tour of the college that can be used by even an individual without any proper gear. Virtual tours are a way for people to experience and explore a place that exists in reality as a physical space via the internet. The old techniques of the virtual tour are either of a pre-recorded video form or just some collections of 360-degree images. To improve the experience, we are creating a 3D virtual environment that the user can access without any restrictions. The user can download the file and can run the program on their desired platform
Un programa para una práctica terapéutica
Authors: García Carbajal Raquel
Published: February 2024

La palabra terapia es un término que se asocia actualmente con técnicas de medicina y psicología, sin embargo, no siempre ha sido así. En este texto se explica como en la antigüedad clásica la medicina y la filosofía estaban íntimamente relacionadas. Werner Jaeger explica este vínculo, a través del estudio de la filosofía jónica. Por su parte, la filósofa Martha Nussbaum sitúa la mirada en corrientes helenísticas, en estas permea la tradición ética de las escuelas socráticas, lo anterior sirve de preámbulo a la propuesta de una práctica terapéutica fundamentada en el pensamiento de Séneca. Adicionalmente, es importante señalar que esta propuesta se inscribe dentro de una discusión filosófica más general, que ha identificado diversos discursos hegemónicos, predominantemente negativos sobre la vejez y que la intención de acudir al pensamiento de Séneca y examinar su concepto de vejez, responde igualmente a la necesidad de revisar dichos discursos, con miras a contribuir en la construcción de un programa terapéutico de la vejez.
ESG and venture capital research: A bibliometric literature review at the intersection of two fields
Authors: De Silva Cristina , Bosio Andrea Odille , Gervasoni Anna
Published: February 2024

In recent years, there has been a growing interest in concepts of ESG (environmental, social, governance), SRI (socially responsible investing), and Impact investing among academics and practitioners. This increased attention can be attributed to the notable support from institutional investors and policymakers who are pushing for more sustainable and socially responsible investment practices. This change poses many challenges and offers great opportunities to the venture capital (VC) sector, as it will define the new standard for investments. Against this backdrop, the paper aims to analyse the nascent body of literature at the intersection between the research field of “ESG” and “venture capital”, using a bibliometric literature review. The results highlight the key groundwork and future research directions for academics. We show the need to integrate these new practices in a comprehensive framework. Our findings aim to support practitioners and policymakers, as we synthesize the key literature, authors, and themes of the academic debate working specifically in this interdisciplinary field.

Authors: Serrano Carlos , Jacome Edwin , Pozo Edwin , Choto Santiago , Abarca Patricio , Bunay Jorge
Published: February 2024

In both turbulent and laminar pipe flows, we were able to accurately forecast the beginning range of the convective thermal transferring coefficients of Al2O3 magnetized nanofluids using machine learning approaches. The simulations utilized two machine learning techniques: radial basis function-backpropagation (RB) and multiple linear regression analysis. First, we used multiple linear regression analysis to fit the polynomial equation. Afterwards, grid search cross-validation was employed to determine the optimal RB model with six hidden layer neurons. To evaluate the RB model, we compared numerical patterns of the parameters used to measure accuracy. The regression coefficient and mean square error were the most commonly utilized parameters in Reynolds number mass percentage simulations, R2. In the case of a laminar flow, these numbers were found to be 0.99994 and 0.34, respectively. Additionally, the results for laminar flow conditions using Reynolds number-magnetic field strength simplification were ideal, with an mean square error of 3.85 and an R2 value of 0.99993. By comparing the predicted values with the experimental results visually using 3-D smoothed surface plots, we were able to further prove that the model was valid and accurate. These revolutionary findings could spark new developments and encourage substantial improvements in nanotechnology and machine intelligence. These findings are an important asset for driving future research and development, which in turn makes significant contributions to the ever-expanding frontiers of these innovative fields.

The Mg/2.4 wt.% CNP composite has a specific heat capacity improvement of 174%, according to DSC testing results. The TGA data reveals a 2.4% decrease in mass when comparing the Mg/2.4 wt.% CNP composite to pure Mg. The coefficient of heat transfer, the effectiveness of the fin, and the heat conduction via fin were all evaluated with a pin-fin transferring of heat under conditions of both free and forced convection. When carbon nanoplatelets are added to a Mg matrix, the resulting composites have better heat transfer characteristics when subjected to both natural and artificial convection.
Comparative analysis of CFD and ANFIS for predicting heat transfer enhancement in water-Fe2O3 nanofluids across various flow regions
Authors: Espín German-Santiana , Parra Fernando-Castillo , Santos Katherine-Campoverde , Buenano Luis
Published: February 2024

Models for enhancement of heat transfer in nanofluids made wide use of adaptive neural fuzzy inference system (ANFIS) and the multi-phase mixture model in recent years. These models originate from two separate but complementary branches of engineering: computational mechanics and machine intelligence. Not only have prior studies used only a small subset of nanofluid and flow parameters in their analyses, but no one has ever compared the two methods to determine which one is more applicable to certain flow regimes to forecast how much heat transfer development nanofluids will exhibit. The purpose of this study was to compare the accuracy of two methods ? CFD and ANFIS in predicting the heat transfer improvement of water-Fe2O3 nanofluid for variety of nanofluid formations and flow characteristics, and recommend the method that would be most useful in predicting this enhancement for each flow regime. While ANFIS consistently outperforms the mixture models in prediction of nanofluid heat transfer enhancement, the latter can sometimes produce results that differ greatly from experimental correlation; however, for nanofluid configurations, the mixture model?s predictions can be dependable (with 1% error).
Mechanical characterization of fractured granite reservoirs
Authors: Zuo Xiongdi , Dou Liangbin , Zou Hongjiang , Zhang Ming , Li Tiantai , Shi Xiaogang
Published: February 2024

In this paper, on the basis of laboratory triaxial mechanical experiments, a granite model including different numbers and angles of fractures was established by the discrete element method. Combined with the laboratory triaxial mechanical experiments and PCF simulation results, the effects of the number and angle of fractures on the rock mechanical properties of fractured granite reservoirs were analyzed. The results show that the existence of fractures significantly reduces the strength of the reservoir, but the increase of the fracture angle and the confining pressure will weaken the degree of this reduction, and the fractures are easy to expand and connect during the loading process.

Authors: Güncü Arzu , Soyluk Asena , Çelik Alper , Mutlu Erkan Okay
Published: February 2024

In this study, the earthquake behaviour of the historical Çadırcı Bathhouse in Erzincan, which is located on the North Anatolian Fault, the most active fault line of Turkey, was investigated. This historical masonry structure has preserved its structural integrity despite being exposed to two earthquakes of magnitude 7.8 in 1939 and 6.7 in 1992. In accordance with the architectural survey studies, the historical building was modelled in 3D in two different types according to shell and solid modelling techniques. According to the results of response spectrum analysis, stress and displacement distributions and modal characteristic parameters of the structure were evaluated. When the analysis results of the models created with the solid model technique and the shell model technique are compared, it is concluded that the shell modelling technique is safe in such studies, considering the analysis time and modelling difficulty. According to the results of the analyses, considering the stress distribution in the historical building elements, it is seen that the configuration characteristics of historical masonry structures are important in earthquake resistance like other building systems.
Smoking is associated with higher short-term risk of revision and mortality following primary hip or knee arthroplasty: a cohort study of 272,640 patients from the Dutch Arthroplasty Registry
Authors: Bongers Joris , Belt Maartje , Spekenbrink-Spooren Anneke , Smulders Katrijn , Schreurs B Willem , Koeter Sander
Published: February 2024

Background and purpose: Patients actively smoking at the time of primary hip or knee arthroplasty are at increased risk of direct perioperative complications. We investigated the association between smoking status and risk of revision and mortality within 2 years following hip or knee arthroplasty.Methods: We used prospectively collected data from the Dutch Arthroplasty Register. All primary total hip arthroplasties (THAs), total knee arthroplasties (TKAs), and unicondylar knee arthroplasties (UKAs) with > 2 years’ follow-up were included (THA: n = 140,336; TKA: n = 117,497; UKA: n = 14,807). We performed multivariable Cox regression analyses to calculate hazard risks for differences between smokers and non-smokers, while adjusting for confounders (aHR).Results: The smoking group had higher risk of revision (THA: aHR 1.3, 95% confidence interval [CI] 1.1–1.4 and TKA: aHR 1.4, CI 1.3–1.6) and risk of mortality (THA: aHR 1.4, CI 1.3–1.6 and TKA: aHR 1.4, CI 1.2–1.6). Following UKA, smokers had a higher risk of mortality (aHR 1.7, CI 1.0–2.8), but no differences in risk of revision were observed. The smoking group had a higher risk of revision for infection following TKA (aHR 1.3, CI 1.0–1.6), but not following THA (aHR 1.0, CI 0.8–1.2).Conclusion: This study showed that the risk of revision and mortality is higher for smokers than for non-smokers in the first 2 years following THA and TKA. Smoking could contribute to complications following primary hip or knee arthroplasty.

Published: February 2024

The ecological-edaphic and morphological features and the state of populations of the endemic species Moehringia hypanica Gryn & Klokov within the steppe zone of Ukraine were investigated. According to the results of laboratory studies, the humus content of the soil where M. hypanica grows is high, amounting to 7.35-8.23%. According to the results of our research, the availability of soil mobile nutrients showed that the concentrations of Mg, and P₂O₅ were very high, and 8.5-15.0 mg/kg, 129.6-164.5 mg/kg, respectively, and Ca concentration was high and very high, which corresponds to 12.5-27.5 mg/kg. The N concentration of the substrate increased in the samples (256.2-268.8 mg/kg), and the S concentration varied between very low and low (1.3-4.8 mg/kg). This indicated high concentrations of Mg, P₂O₅, and Ca in the substrate and as a limiting factor for the successful growth of the studied plants. The analysis of the cationic and anionic composition of the water extract showed that the soil was classified as non-saline (the sum of salts did not exceed 0.1%). The content of all salts did not exceed the toxicity thresholds. It has been established that in order to preserve the populations of this endemic plant, it is necessary to maintain a stable chemical composition of the substrate and prevent human intervention. During the expeditionary research, we noted that the populations are dominated by young generative and medium generative plants, with a small number of old generative and virgin individuals.

Published: February 2024

Neonatology in Russia had demonstrated significant success over the past three decades that in its turn has led to an unprecedented decrease in infant mortality rates primarily due to a decrease in early-neonatal and neonatal mortalities. These achievements were mostly caused by the implementation of the “Healthcare” national project with a large number of perinatal centers being deployed overall Russia, introduction of a multi-level system for providing care to pregnant women from high-risk groups, with high-quality diagnostic and therapeutic equipment installed therein coupled with life-saving drugs availability. Which is more important is that Russian domestic manufacturers have significantly succeeded during the mentioned period in the production of high-tech medical equipment and consumables as well as drugs that are in use in neonatology with some of them having none of its kind abroad.

Acute intestinal infections caused by opportunistic microflora (OPM) are a pressing problem in infants. The purpose of this research was to investigate the treatment of enterocolitis caused by OPM in infants using antibacterial drugs and their detection by bacteriophages. Materials and methods used: a single-center retrospective cohort study of 106 pediatric patients aged 1 month to 1 year old with mild to moderate severity of acute intestinal infections caused by OPM and treated with an antibacterial drug (nifuroxazide), a bacteriophage (complex liquid pyophage) or a combination thereof, who were divided into the three groups as follows: G1 (“Nifuroxazide,” n=39), G2 (“Pyophage,” n=33) and G3 (“Combined drugs,” n=34), was conducted at the Scientific and Research Institute for Children’s Infections of the Russian Federal Biomedical Agency (Saint Petersburg, Russia) in 2018-2021. Data on pathogen elimination and duration of symptoms in patients were analyzed. The criteria for the effectiveness of therapy were the normalization of temperature, stool and coprograms and a decrease in the OPM titer in feces to a level of ≤104 CFU/g. Results: achievements of all applications of successful therapy occurred more often in G3 compared to G1 (0.007). An increased risk of treatment failure was evidenced by patients having OPM in a stool at the level of over 109 CFU/g (RR=14,09 [2,84; 69,96]) and the “visible entire” presence of erythrocytes (RR=6.26 [2.51; 15.62]) and leukocytes (RR=5,51 [2,22; 13,67]) in a coprogram. The probability of a response to therapy when using the active substances Nifuroxazide+Pyophage was lower (0.120 [0.037, 0.389]) than with monotherapy with Pyophage (0.227 [0.074, 0.692]) or Nifuroxazide (2.678 [1.14, 6.297]) alone. Conclusion: combined therapy of acute intestinal infections caused by OPM in infants using the antibacterial drugs coupled with Pyophage increases the effectiveness of OPM elimination and the disease’s clinical and laboratory symptoms’ relief.

Breastfeeding is commonly acknowledged as being the biological norm. In cases when a child cannot be latched to the breast, freshly expressed mother's milk is the first choice that in specific conditions may require pasteurization. In accordance with the Russian sanitary rules and regulations as of 2021, “human milk is processed by boiling it in a water bath,” which is extremely destructive for the most of its biologically active and important components. The global practice of thermal processing of human milk is its low-temperature pasteurization according to the Holder method for 30 minutes at the temperature of +62.5°C. Currently there are no Russian domestically produced breast milk (BM) pasteurizers whilst it is not always possible to purchase imported equipment as yet. The purpose of this research was to assess the bacteriological safety of BM pasteurization using the laboratory water bath PE-4300 domestically produced by “ECROSKHIM” in Saint Petersburg, Russia, which allows the reproducing of the Holder method. Materials and methods used: a prospective single-center study of 153 lactating mothers was conducted with 306 BM samples being subjected to bacteriological analysis prior to and after the pasteurization. Results: before pasteurization, the growth of opportunistic bacteria was detected in all BM samples mainly due to the growth of S. epidermidis. After pasteurization, 96.1% of BM samples turned out to be sterile. In the remaining 3.9%, the scant growth of S. epidermidis (2.6%), Streptococcus oralis (0.65%) and Acinetobacter (0.65%) was not clinically significant. Conclusion: BM pasteurization in the laboratory water bath ECROSKHIM PE-4300 demonstrated high bacteriological safety of the device’s final revision, which in its turn allowed Authors to recommend this method of processing of both maternal and donor BM in pediatric and perinatal facilities.

Significant progress has been achieved in the study of COVID-19 so far. Some authors prove an increase in the frequency of critical conditions and the overall morbidity of newborns from mothers who have had COVID-19 during pregnancy. Materials and methods used: a prospective cohort study was conducted in Jan. 2021-Dec. 2022 comparing two groups of 107 each of neonates born in severe condition. In the first group of newborns, mothers were diagnosed with COVID-19 during pregnancy; in the second group, mothers did not have acute respiratory viral diseases. Results: children from mothers who had COVID-19 were statistically significantly more likely to have respiratory disorders (p<0.001), congenital pneumonia (p<0.001), perinatal period infection (p<0.001), intraventricular hemorrhages (p<0.001) and hyperbilirubinemia (p=0.040). In the blood test, a statistically significant decrease in the content of erythrocytes, hemoglobin and hematocrit values (p<0.001), lymphocytes (p=0.041) and band neutrophils was noted. A biochemical blood test revealed an increase in total bilirubin (p=0.034) and creatinine (p=0.030). The most critical is the birth of a child within 1st to 3rd weeks after the mother’s COVID-19, when the highest incidence of pneumonia and DIC syndrome was recorded in newborns, OR=6.8 [1.95; 23.66] and deaths, OR=17.75 [2.08; 150.93]. More distant consequences can be considered fetal growth retardation syndrome, OR=1.8 [1.55; 5.87], increased incidence of malformations and minor anomalies in the development of the newborn, OR=1.75 [1.02; 4.90]. Conclusion: morbidity and severity of the condition of the newborn depends on the period between the infectious process of COVID-19 of the mother and the birth of the child.

Neste estudo, partimos da seguinte questão: qual a situação profissional e a intervenção socioeducativa dos diplomados em Educação Social, em 2017/18 e 2018/19, numa Instituição de Ensino Superior (IES) privada em Portugal. Elencámos como objetivos: caracterizar a situação profissional dos diplomados e analisar a sua intervenção socioeducativa, após a conclusão do curso. Foi construído, testado e aplicado um questionário, de questões abertas e fechadas. Procedeu-se ao tratamento da informação, mediante os descritores: (i) caraterização dos participantes; (ii) motivações e expetativas; (iii) nível de satisfação académica; (iv) oportunidades profissionais. Constatou-se a precaridade e baixos salários no que reporta à situação profissional dos diplomados; um elevado nível de satisfação em relação à formação e dificuldade em obter emprego na área da formação, por pouca oferta de emprego, devido ao desconhecimento da área e do seu potencial. Conclui-se sobre a importância da divulgação da formação de um perfil holístico do Educador Social (ES), sustentado por competências socioprofissionais e um saber pedagógico e social específico que se consolide como vetor de empregabilidade, em territórios e contextos diversificados, capazes de responder aos desafios da contemporaneidade.

O ensino de investigação qualitativa associa-se ao estudo dos processos pedagógicos mais adequados à aquisição de competências de investigação. Assim, pretende-se contribuir para o (re)conhecimento da importância da investigação qualitativa e da sua lecionação, através da análise do impacto percebido pelos alunos da frequência de uma unidade curricular de métodos de investigação. Participaram 10 alunos na primeira fase do estudo e 11 alunos na segunda fase, que frequentavam um curso de 2.º ciclo, em Psicologia da Educação, numa Universidade Pública Portuguesa, no ano letivo 2019/2020. A recolha de dados foi feita através de narrativa, tendo sido alvo de análise de conteúdo por duas codificadoras, numa lógica dedutiva e indutiva. O ensino de investigação qualitativa teve impacto nos alunos, destacando-se a evolução e aprofundamento ao nível da caracterização da metodologia qualitativa e da sua importância, bem como o desenvolvimento de competências investigativas e de possibilidade de transferência da aprendizagem. Os alunos reconheceram ainda a pertinência da unidade curricular ao nível do mestrado em questão, sugerindo a iniciação à mesma mais cedo no percurso académico. O estudo contribui para o reconhecimento da lecionação de investigação qualitativa, com possíveis implicações na revisão dos planos de estudo do primeiro ciclo em Psicologia.

Quando se trabalha com crianças com Perturbações do Espetro do Autismo, percebe-se que a maior dificuldade radica na promoção da sua comunicação e socialização. O presente estudo de carácter qualitativo e exploratório, foi realizado no Brasil no ano de 2017. Centrou-se na utilização de um Pequeno Filme no qual uma criança com Perturbação do Espetro do Autismo seguia as instruções de um Professor de Música através de um vídeo num telemóvel. Este Pequeno Filme foi analisado através da técnica de análise de conteúdo suportada pelo software na plataforma webQDA. Teve como objetivo observar as Funções de Comunicação e as Formas de Comunicação que a criança com Perturbação do Espetro do Autismo utilizava durante duas situações. Observámos a existência de limitações nas Formas de Comunicação e nas Funções de Comunicação da criança em estudo, tendo existido algumas melhorias com a introdução do vídeo através do Telemóvel. Como Conclusão, observamos que o telemóvel parece poder contribuir para tornar acessível a informação para as crianças com Perturbação do Espetro do Autismo, nomeadamente na melhoria da sua comunicação. Por último, é sugerida a realização de mais estudos de cariz experimental que contemplem a observação em vários contextos.

Este texto constitui-se em um exercício analítico-reflexivo e traz como ideia central a perspectiva das cidades educadoras como possibilidade e condição para a construção de sociedades sustentáveis. Aponta elementos das distopias contemporâneas ao mesmo tempo que traz aportes de diferentes documentos e convenções internacionais que explicitam vontades coletivas para podermos viver juntos e com dignidade. Sublinha aspectos das Cartas das Cidades Educadoras escritas, desde a cidade de Barcelona, nos anos de 1990 e 2020 e dialoga com autores como Henry Lefebvre, Milton Santos, Paulo Freire, entre outros, para pensar a cidade desde a perspectiva de seus serviços, políticas e equipamentos; de suas gentes em diferentes tempos da vida com seus desafios geracionais e intergeracionais; e, desde as possibilidades da instituição escolar, a partir de um horizonte alargado de compreensão da educação como processo de humanização. Afirma a possibilidade de construirmos outros cenários sociais que alimentem a utopia da democracia e da dignidade humana.
