Bithyniids are freshwater snails that play a crucial role in the transmission of various parasitic trematodes of medical and veterinary importance. In this study, we explored the prevalence of cercarial trematode infections in bithyniid snails from Thailand and examined the species diversity of both the intermediate snail hosts and parasite larvae. A total of 688 bithyniid snails were collected from diverse natural habitats at 24 locations in 16 provinces across 5 regions of Thailand. The presence of larval trematode infections was examined using the cercarial shedding method. Both the collected snails and the emerging cercariae were identified at the species level using a combination of morphological and molecular techniques. The mitochondrial COI and 16S rDNA sequences of bithyniid snails, along with the ITS2 sequences of cercariae, were obtained via PCR amplification and sequencing. Three species of bithyniid snails were identified in this study: Bithynia funiculata, Bithynia siamensis siamensis, and Hydrobioides nassa. Among these species, B. s. siamensis exhibited the highest population density, followed by B. funiculata and H. nassa. The overall rate of cercarial infection in the bithyniid snails was relatively low, at 1.45%. H. nassa snails had the highest infection prevalence, at 11.11%, while B. s. siamensis had a prevalence of 1.39%. Only the morphological type of the xiphidiocercariae was detected. BLASTn searches in GenBank and phylogenetic trees based on xiphidiocercariae were used to classify the samples into four different families spanning two superfamilies of digenean trematodes. The genera Plagiorchis, Prosthogonimus, Paralecithodendrium, and cercaria of Renicolidae are reported for the first time in B. s. siamensis. Plagiorchis and Paralecithodendrium are significant genera of zoonotic trematodes. These findings indicate that B. s. siamensis and H. nassa can act as the first intermediate hosts for various parasitic trematodes in Thailand.

Authors: Lu Yingjie , Tuo Hong , Fan Haoyi , Yuan Haiying
Published: February 2025

The demand for big data talent is rapidly increasing with the growth of the big data industry. However, there has been limited research on what employers seek in recruiting big data talent. This paper aims to apply labor market segmentation theories to the big data labor market and develop a theoretical framework to analyze the distribution of big data talent in different labor market segments. Furthermore, we develop a salary determination model to explain wage differentials. An empirical analysis is conducted using online job advertisements from a Chinese recruitment website to investigate the labor market for big data talent in China. Our findings show that there are significant differences in the demand for big data talent across different types of cities and industries. Different types of enterprises have different requirements for individual characteristics and offer various levels of big data job positions. Furthermore, our results reveal that individual, job-related and organizational characteristics are all significant predictors of salaries. These findings can provide particularly useful insights for organizations and managers in the big data industry.
The effect of interdisciplinary treatment on sickness absence and disability pension among chronic pain patients on partial disability pension
Authors: Constan Lea , Frumento Paolo , LoMartire Riccardo
Published: February 2025

Studies evaluating the effects of interdisciplinary treatment (IDT) on sickness absence and disability pension (SA/DP) have yielded contradictory findings. Evidence indicates that positive treatment effects are restricted to patients with a poor SA/DP prognosis. This study therefore analyzed the effect of IDT in working age patients on partial disability pension, which is a group with a particularly poor prognosis. With data from 479 patients on partial disability pension, this register-based cohort study compared the effects of IDT to those of unspecified interventions. We considered two response variables: total net SA/DP days across the span of three years from the first visit to a Swedish specialist pain clinic, and the risk of having the maximum possible 1096 SA/DP days over the same period. Our results showed that both the total net SA/DP days (mean difference: 11; 95% confidence interval: -30 to 51) and the risk of 1096 SA/DP days (risk ratio: 1.0; 95% confidence interval: 0.6 to 1.4) were similar irrespective of intervention type. Under our theoretical model, we thereby found no support in favor of IDT over less intensive interventions in working age patients with partial DP. This raises questions about the specific criteria under which IDT proves effective.

Published: February 2025

Zinc fingers (ZFs) are compact, modular, sequence-specific polynucleotide-binding domains uniquely suited for use as DNA probes and for the targeted delivery of effector domains for purposes such as gene regulation and editing. Despite recent advances in both the design and application of ZF-containing proteins, there is still a lack of a general method for their expression and purification. Here we describe a simple method, involving two chromatographic steps, for the production of homogeneous, functional ZF proteins in high yield (one milligram per liter of bacterial culture), and we demonstrate the generality of this method by applying it to a diverse set of eight C2H2-type ZF proteins. By incorporating a surface-exposed terminal cysteine residue that enables site-specific conjugation with maleimide-activated fluorophores, we confirm the suitability of these probes for in situ labeling of specific DNA sequences in human cells.

Authors: Khan Md. Nuruzzaman , Khan Md. Mostaured Ali , Billah Md Arif , Khanam Shimlin Jahan , Haider Md. Moinuddin , Sarker Bidhan Krishna , Harris Melissa L.
Published: February 2025

Background

Access to modern family planning is critical for improving maternal and child health outcomes, yet it remains severely lacking in low- and middle-income countries, including Bangladesh. Maternal healthcare utilization during and after pregnancy is vital for promoting postpartum family planning. This study examined the effects of maternal healthcare service utilization on postpartum family planning uptake in Bangladesh.

Methods

Reproductive calendar data from 4,081 women with recent live births were extracted from the cross-sectional 2017/18 Bangladesh Demographic and Health Survey and analyzed. The outcome variable was uptake of modern postpartum family planning methods and the exposure variables were different types of maternal healthcare services. Kaplan-Meier methods were used to calculate cumulative probabilities of modern postpartum family planning method uptake within 12 months post-delivery, and modified Poisson regression models were used to estimate the effects of utilizing maternal healthcare services on modern postpartum family planning method uptake.

Results

Modern family planning methods in the 12 month postpartum period were used by 72% of women, with over 60% starting after day 40. Less than 4% used long-acting family planning methods, while almost 40% relied on the oral contraceptive pill. Utilizing maternal healthcare services was associated with up to a 7% higher uptake of modern postpartum family planning methods compared to non-users.

Conclusion

Three-quarters of Bangladeshi women use modern family planning within the 12 months postpartum, but often rely on less effective methods. Additionally, 25% of these women resort to traditional or no use of contraceptive methods, increasing the risks of unintended pregnancy, short birth intervals, and adverse maternal and infant health outcomes. Maternal healthcare services, including private facilities, should prioritize modern postpartum family planning provision, along with education and counseling on the benefits of long-acting contraception.

Published: February 2025

Burnout among critical care physicians is an important issue that affects patient care and staff well-being. This study, conducted by the Korean Society of Critical Care Medicine, aimed to investigate the prevalence and associated factors of burnout among intensivists and critical care fellows in South Korea. From May to July 2019, a cross-sectional survey was conducted in 51 hospitals and 79 intensive care units offering subspecialty training in critical care medicine. Invitations were sent by email and text, and responses were collected using NownSurvey and Google Forms. Of the 502 invited participants, 253 responded (response rate: 50.4%). Significant contributing factors of burnout included being in an intensivist position (assistant professor/fellow) (odds ratio [OR], 3.916; 95% confidence interval [CI], 1.485–10.327; p = 0.006), working in a medical ICU (OR, 4.557; 95% CI, 1.745–11.900; p = 0.002), the number of stay-home night calls per month (OR, 1.070; 95% CI, 1.005–1.139; p = 0.034), and recent conflicts with colleagues (OR, 5.344; 95% CI, 1.140–25.051; p = 0.033). Similar factors were found to influence severe levels of burnout. This nationwide study indicates that a significant proportion of critical care physicians in South Korea experience burnout. Strategies to reduce overtime and workplace conflict are imperative to reduce burnout among these physicians and protect their mental health. Future research should explore targeted interventions for these specific factors.

Published: February 2025

Objective

This study used a dental model scanner and best-fit alignment to analyze the deformation patterns of stabilized occlusal appliances (OcAs) used to treat sleep bruxism when stored in wet or dry conditions.

Methods

Eight OcAs were prepared using polymethyl methacrylate, stored in water at room temperature for 4 weeks (wet storage), and then in air for 4 weeks (dry storage). After being stored in water for one month for hydration, they were 3D-scanned and digitized on days 0, 28, and 56. 3D-deformation patterns were obtained by comparing the storage-D group data using a best-fit alignment program that aligns the nearest points of the corresponding images in a virtual space and calculates the difference between the two images. The maximum deviation and deformed area in the ± direction, and the volume of the wet (W) and the dry (D) condition groups were compared using Wilcoxon’s signed rank test.

Results

OcA showed no obvious deformities in the W group at 4 weeks. However, in the D Group, a typical deformation pattern was detected at 4 weeks, with the posterior margin of the molars shrinking anteriorly, the palatal side of the molars lifted, and the buccal side retracted inward. The Ⅾ group was significantly larger than the W groups in terms of maximum deviation in the ± direction, deformed area, and volume.

Conclusions

After 4 weeks of storage under dry conditions, OcA showed a typical deformation pattern of shrinkage toward the center, with in-center lifting toward the palatal side. Significantly greater surface deviations, deformation areas, and deformation volumes were observed under dry conditions than in wet conditions.
Increased NFAT and NFκB signalling contribute to the hyperinflammatory phenotype in response to Aspergillus fumigatus in a mouse model of cystic fibrosis

Published: February 2025

Aspergillus fumigatus (Af) is a major mould pathogen found ubiquitously in the air. It commonly infects the airways of people with cystic fibrosis (CF) leading to Aspergillus bronchitis or allergic bronchopulmonary aspergillosis. Resident alveolar macrophages and recruited neutrophils are important first lines of defence for clearance of Af in the lung. However, their contribution to the inflammatory phenotype in CF during Af infection is not well understood. Here, utilising CFTR deficient mice we describe a hyperinflammatory phenotype in both acute and allergic murine models of pulmonary aspergillosis. We show that during aspergillosis, CFTR deficiency leads to increased alveolar macrophage death and persistent inflammation of the airways in CF, accompanied by impaired fungal control. Utilising CFTR deficient murine cells and primary human CF cells we show that at a cellular level there is increased activation of NFκB and NFAT in response to Af which, as in in vivo models, is associated with increased cell death and reduced fungal control. Taken together, these studies indicate that CFTR deficiency promotes increased activation of inflammatory pathways, the induction of macrophage cell death and reduced fungal control contributing to the hyper-inflammatory of pulmonary aspergillosis phenotypes in CF.

In this article, we introduce PolyCool, an all-organic, per- and polyfluoroalkyl substances (PFAS)-free coating designed for passive, all-day cooling applications. The coating utilizes porous polyethylene (PE), produced via a straightforward dip-coating and phase-inversion process, achieving a polydisperse pore size distribution that facilitates exceptional solar reflectance of 97.4%. To enhance its emissivity, polydimethylsiloxane (PDMS) particles synthesized through a green emulsification method, enabling scalable and size-controlled production, were incorporated. During a 36-hour continuous test in London, the developed coating achieved subambient temperature reductions of 2 °C under direct sunlight and 5.5 °C at night. These results were obtained without the use of convective shields, despite partial cloud coverage and humidity levels exceeding 40%. The radiative cooling potential of this coating has been estimated for 10 major European cities based on its spectral data and meteorological conditions. Additionally, the surface texturing of the coating enabled superhydrophobic properties, with a contact angle exceeding 160°. The coating also exhibited excellent ultraviolet (UV) resistance and can be applied to a range of substrates, including polymer films, aluminum foil, and wood, with minimal equipment and material costs.
Academic Demands and Eye Health: Prevalence and Quality of Life Effects of Dry Eye Disease among University Students
Authors: A.S. Qaddumi Jamal
Published: February 2025

Background: Dry Eye Disease (DED) is a common disease in the ophthalmic world,
characterized by eye irritation, foreign body sensation, stinging, photophobia, and blurred
vision. Purpose: This study aimed to measure the quality of life (QOL) for dry eye
participants among An-Najah University students. Methods: A cross-sectional study was
used. Students aged between 17 years and 24 years were selected based on a convenient
selection; the total number of research subjects was 481. Data was collected in two steps at
the same time: the first step includes giving the students the Ocular Surface Disease Index
(OSDI) questionnaire to diagnose whether they have a dry eye disease or not. Then, they
were asked to fill out the Visual Function Questionnaire (VFQ-25) to know how DED
affects their QOL. Results: The prevalence of dry eyes in Palestine was 69.4%. Also, it was
revealed that dry eyes are significantly associated with QOL, with an impact on students’
daily life activities. Conclusion: Our results have shown that quality of life is inversely
proportioned with dry eye severity, showing that dry eye affects a person’s daily life
activities. Implications for Nursing: The findings of this study may increase nurses'
awareness regarding DED and offer appreciated data for public health promotion in
adolescents. Additional investigation is vital to have a better understanding of additional
probable parameters linked to DED.

School Bullying is Occurring Everywhere: A Need for Effective Anti-bullying Strategies
Authors:   Jordan University of Science and Technology, Al-Natour Ahlam
Published: February 2025

Background: Teachers play a crucial role in screening bullying, as well as in increasing
students’ awareness towards bullying. There is a dearth of studies that describe teacher
perceptions about bullying among students. Purpose: This study aimed to describe teachers'
perceptions about bullying among students at schools. Methods: A qualitative descriptive
design was used among 24 teachers from five public schools. Content analysis was used to
find out the study themes, patterns of ideas, and relationships. Results: Three themes
emerged: (1) the shocking experience of witnessing bullying, (2) teachers’ perceptions of
the predisposing factors of bullying, and (3) the hazardous impact of bullying on victims
and on the school environment. Teachers provided a new understanding of bullying at
schools and its causative factors. Conclusions: Bullying could end with a hazardous impact
on students and the school environment. Policymakers and school nurses should implement
anti-bullying strategies and legislations to ensure a safe school environment for school
teachers, administrators, and social counselors. Implications for Nursing: Teachers and
school nurses could play crucial roles in screening, reporting, and referring in the incidence
of school bullying. Also, they could play a significant role in implementing anti-bullying
strategies, taking into consideration the active engagement of students, parents, teachers,
social counselors, policy makers, and school principals. Cultural strategies should be taken
into consideration when implementing anti-bullying programs and strategies at different
levels, including family, school and community levels. The role of school nurses is vital in
fighting school bullying and mitigating its adverse impacts on students as well as on the
school environment.

Published: February 2025

A famous vegetable crop in India that is rich in nutrients and heavily dependent on bees for pollination is moringa. A survey was taken in the Karur and Perambalur districts of Tamil Nadu to document the diversity of pollinators and insect visitors of moringa. The observations were analyzed using diversity indices. According to the studies, 13 hymenopteran, 7 dipteran, and 7 lepidopteran insects visited moringa plants. Fruit set and quality are maximized in moringa when pollination is successful. Therefore, four treatments have been applied to the Asiatic hive bee, Apis cerana indica, to explore the pollination capability and the foraging ecology of other key bee pollinators of moringa. The results affirmed that the significant Apis pollinators spend more time on nectar collection than pollen gathering. The peak foraging activity of Apis pollinators happened in the morning hours during 0900 -1100h. A. cerana indica and A. dorsata commence their foraging activity much earlier in the morning than A. florea. The foraging activity gradually declined after 1400h. The abundance of A. cerana indica was very high in managed bee pollination plots compared to open pollination plots. The managed bee pollination plots (128.2 fruits/tree) recorded 19.14 percent more fruit sets and 11.40 % more fruit yield than open pollination plots (107.6 fruits/tree) by deploying four Asian bee colonies per acre of moringa crop.
Internalizacja popkulturowych wzorców atrakcyjności fizycznej przez użytkowników mediów społecznościowych – konteksty społeczno-kulturowe i edukacyjne
Authors: Leksy Karina
Published: February 2025

The article aims to present social media’s importance for internalizing the ideal body promoted in popular culture. Internalization of a culturally and socially desirable body image is associated with body image disorders, low self-esteem, and risky behaviors aimed mainly at reducing body weight among women and increasing musculature among men. The research presented in the article was conducted on 493 young adults via an online survey. In the group of women, the statistical analysis showed a correlation between the degree of agreement with the statement about the role of social media as a source of information about fashion and physical attractiveness and the preference for thinness. This result suggests the small body shape’s internalization by the surveyed women. It indicates the need for psychoeducational activities in the critical reception of media content and education in healthy attitudes towards one’s body.

The issues of the proposed analysis are based on the issue of creating a young person’s identity in the 21st century. The development and availability of digital media offers a range of opportunities that cannot be ignored today. However, the basis here seems to be the ability to navigate in the digital world. The subsequent stages of life verify so deeply the entirety of a person’s experiences and experiences that, as a consequence, they require flexibility also in the area of continuous shaping of one’s own internal representation. The development of the COVID-19 pandemic has significantly contributed to the “imposed” need for deeper immersion in the digital world as a result of the introduction of remote work and remote forms of education, at all levels. Restrictions on interpersonal contacts have increased the intensity of using social media, especially in view of the increased need for closeness, fear, and the feeling of being cut off from existing relationships and their forms. The proposed considerations are an attempt to look at the issue of identity creation in the context of the above-mentioned events and the series of consequences they brought.

Authors: Martincová Jana , Staňková Iva
Published: February 2025

The main objective of this study is to analyse the changes in social education professional internship for university students. We concentrated on identifying strengths and weaknesses of professional internship, and the opportunities and threats observed in the implementation of professional social education professional internship during the coronavirus crisis. We subsequently explain how the impacts of this extraordinary situation are reflected in the competency model of the future social educator. Due to the absence of specific research studies looking at the transformation of student professional internship during the coronavirus crisis period, we thought it seemed appropriate to investigate in detail one specific case, and use it to analyse the partial impacts of the pandemic in the implementation of the professional internship of specifically university students. Using a descriptive case study design, we analyze social education internships during the coronavirus period in the Czech Republic, utilizing student data (internship diary, facility assessment, self-assessment, and questionnaire) to identify changes in the internship system. We found many significant changes in the implementation of professional internship, which are fundamentally reflected in the competency model of Social Education graduate.

Aktywność cyfrowa seniorów i jej znaczenie dla partycypacji osób starszych w życiu online na platformach społecznościowych
Authors: Sikorska Joanna
Published: February 2025

Internet use is no longer reserved exclusively for young people. In recent years, an increasing number of seniors have started using it, and they currently constitute a significant group of users, as shown, among other things, by the results of the 2019 Polish survey conducted by the senior citizens portal https://cafesenior.pl/. While the analyses indicate that email and search engines are still the most important internet functions for this group of people, one can also see a marked increase in seniors’ interest in social media platforms. Although this trend has been going on around the world since 2010, in contrast to many European countries, where indicators reach over 80% among people 60+, in Poland only one-fifth of older people have actively participated in social media. The article has the character of a contributory socio-pedagogical sketch on socially important issues related to the e-inclusion of seniors in cyberspace and its determinants, areas of participation of people aged 60+ in social media and selected stimulators and inhibitors of their digital participation in online social life.

Comparative analysis of cutting methods and their impact on fatigue properties of armor steel
Authors: Uzunali Umut Yaşar , Çuvalcı Hamdullah , Kartal Ümit
Published: February 2025

Armor steel is widely used in various industries due to its exceptional yield strength and hardness. However, the cutting processes employed to shape these materials, such as laser and waterjet cutting, may exert a substantial influence on the fatigue resistance of the end product. Fatigue strength is a critical property in materials science, particularly when it comes to high strength steel. As industries strive for lighter and more efficient structures, the demand for materials with superior fatigue resistance becomes paramount. In this article, it is aimed to investigate the effects of laser and waterjet cutting processes on the fatigue strength of armor steel based on experimental results, highlighting the implications for structural integrity and performance. The samples cut by water jet and laser cutting processes were subjected to fatigue tests with and without anti-buckling apparatus. Fatigue tests were carried out at least four different stress values and S–N diagrams were created for 4 different situations. As a result of this study, it was determined that the fatigue strength of samples obtained by laser cutting method is lower than that of waterjet cutting samples. Additionally, it was observed that the fatigue strength of the samples using anti-buckling apparatus was higher.

Ex vivo functional characterization of mouse olfactory bulb projection neurons reveals a heterogenous continuum
Authors: Gadiwalla Sana , Guillaume Chloé , Huang Li , White Samuel JB , Basha Nihal , Petersen Pétur Henry , Galliano Elisa
Published: February 2025

Mitral and tufted cells in the olfactory bulb (OB) act as an input convergence hub and transmit information to higher olfactory areas. Since first characterized, they have been classed as distinct projection neurons based on size and location: laminarly-arranged mitral cells with a diameter larger than 20μm in the mitral layer (ML), and smaller tufted cells spread across both the ML and external plexiform layer (EPL). Recent in vivo work has shown that these neurons encode complementary olfactory information, akin to parallel channels in other sensory systems. Yet, many ex vivo studies still collapse them into a single class, mitral/tufted, when describing their physiological properties and impact on circuit function. Using immunohistochemistry and whole-cell patch clamp electrophysiology in fixed or acute slices from adult mice, we attempted to align in vivo and ex vivo data and test a soma size-based classifier of OB projection neurons using passive and intrinsic firing properties. We found that there is no clear separation between cell types based on passive or active properties. Rather, there is a heterogeneous continuum with three loosely clustered subgroups: EPL tufted cells, and putative tufted or putative mitral cells in the ML. These findings illustrate the large functional heterogeneity present within the OB projection neurons and complement existing literature highlighting how heterogeneity in sensory systems is preponderant and possibly used in the OB to decode complex olfactory information.

Significance statementMitral and tufted cells in the olfactory bulb have traditionally been either grouped due to their shared role in early odour processing, or separated into distinct groups based on in vivo physiology and circuit connectivity. However, our ex vivo study in post-weaning mice reveals a more complex picture. Rather than being clearly distinct or identical, mitral and tufted cells form a diverse continuum of morphological and functional properties. This variability may enable efficient processing of the wide range of odours animals encounter. These findings highlight the importance of considering nuanced differences when classifying neurons in the olfactory bulb and more broadly in the brain.

This research examined methods that are suitable, easy to fabricate, and low-cost for
producing CuBi2O4 photocathodes for application in photoelectrochemical cells. Both spray
pyrolysis and electrochemical deposition techniques were used to produce thin films for
various types of semiconductor electrodes. The CuBi2O4 thin film was coated on fluorinedoped tin oxide (FTO) using spray pyrolysis and electrochemical deposition, followed by
annealing in an oxygen atmosphere. X-ray diffraction (XRD) characterized the crystal
structures, confirming them as Kusachiite. Scanning electron microscopy (SEM) analysis
revealed that CuBi2O4 fabricated by electrochemical deposition exhibited smaller particles,
while the spray pyrolysis method produced a plate-like structure. The optical properties were
investigated using UV-visible reflection, and the energy bandgaps of the products were
estimated using Tauc plots, showing slight differences. Chopped light voltammetry (CLV)
was used to evaluate the photon conversion efficiency of the synthesized photocathodes.
Results indicated that the photocathode made by electrochemical deposition responded
better to light compared to the one made by spray pyrolysis. With 0.5 M Na2SO3 as a
sacrificial agent, the highest photocurrent density obtained was 0.2 mA/cm², while with 0.5
M NaHCO3, the highest photocurrent was 0.5 µA/cm², indicating poorer performance.

Objectives: Because of the higher frequency of dystocic labor in nulliparous pregnant women, a supplementary test is highly important for predicting the probability of the cesarean intervention. The aim of this study was to evaluate the correlation between the amniotic fluid lactate (AFL) level and the outcome of delivery in nulliparous term pregnant women referring with the complaint of the spontaneous rupture of membranes. Materials and Methods: Nulliparous women with term pregnancies and single cephalic presentation, presenting with the spontaneous rupture of membranes and active phase of labor, were enrolled in this study. The AFL was evaluated by a portable device. In addition, the partogram curve, labor progression, and delivery method were recorded for each patient. Finally, the association between the need for cesarean delivery and the AFL level was investigated as well. Results: In general, 200 nulliparous pregnant women were enrolled in this study. The mean age of women and the mean AFL were 29.12±7.54 years and 7.32±3.63 mmol/L, respectively. Among 144 patients with AFL below 10.1 mmol/L, 33 patients (22.9%) had a cesarean delivery. Further, among 56 patients with AFL above 10.1 mmol/L, 42 patients (75%) had a cesarean delivery (P<0.001). Eventually, an AFL level higher than 10.1 mmol/L in predicting the cesarean section had a sensitivity of 85.6% and a specificity of 82.7%. Conclusions: Amniotic lactate levels >10.1 mmol/L in nulliparous women with single-term pregnancy can be used as a marker for predicting cesarean delivery.

Objectives: This study aims to analyze the effects of three types of triggers— human chorionic gonadotropin (hCG), GnRH-a, or a combination of them (dual)—on the quality of oocytes, embryos, and ovarian hyper-stimulation syndrome (OHSS) in the ICSI cycle. Materials and Methods: A prospective case-control study was conducted on 320 women referred to Milad IVF Center, Mashhad, Iran, between May 2016 and June 2019. All the participants underwent an antagonist protocol and were classified according to the trigger type into three groups: 118 patients in the GnRH-a group, 49 in the hCG group, and 153 in a dual group. The outcome measures included the number of metaphase I and metaphase II oocytes, germinal vesicle (GV) oocytes, high-quality embryos, and the rate of OHSS. Results: The three groups did not exhibit statistically significant differences concerning the quantities of retrieved oocytes: M II oocytes, M I oocytes, GV oocytes, and embryos. The dual trigger method resulted in significantly higher embryo quality (P=0.017). In comparison to dual and GnRH-a group triggers, it was observed that women administered with the hCG group trigger displayed an increased occurrence of OHSS, and the number of severe OHSS in the dual trigger was higher than in the GnRH-a and hCG groups. Conclusions: The GnRH agonist alone and the dual trigger can be as effective as the hCG trigger. A GnRH agonist is preferable in high-risk patients. Therefore, it is imperative to administer the treatment based on the patient’s status.

Objectives: This study aimed to determine the impact of COVID-19 on the menstrual cycle of Saudi females in Jeddah City. Materials and Methods: In this cross-sectional study, we conducted a total of 421 online surveys and phone call interviews with participants between 19 and 45 years of age, living in Jeddah City, Saudi Arabia, who were not pregnant, and had no gynecological problems or abnormalities. Interviews and surveys were conducted between January to April 2022, and the data were analyzed using SPSS version 23. Results: Most responders were single and had a normal body mass index (BMI). During the COVID-19 pandemic, the majority (75.8%) did not have heavy, unpleasant periods (54.6%), or missed periods (54.6%, 78.1%, respectively). The majority reported changes observed in terms of premenstrual symptoms (PMS) (61.5%), and libido/sex drive remained unchanged for most (88.1%). Of those who reported heavy periods (n=125), 18.4% (n=23) reported changes. Of the 239 females who did not experience pain before COVID-19, nine (3.8%) reported experiencing it during the pandemic. Conclusions: There were significant changes in the menstrual period of women in terms of bleeding, heavy and painful periods, and small differences in psychological challenges during the COVID-19 pandemic.

Published: February 2025

The study deals with the issue of didactic-methodological fundamentals of the development of future primaryschool teachers’ professional competencies regarding the improvement of primary school students’ universal learning skillsaccording to the requirements of the State Standard through a scientific understanding of approaches to this problem inPedagogy, Psychology, and particular methods. It is noted that the foundation of schoolchildren’s cognitive activity andsuccessful learning activity begins in primary school. The educational activity is considered the leading type of primary schoolstudents’ activity, combining conceptual structures (learning task, educational action, control, and assessment action). Theauthors of the research emphasize that early school age is sensitive to cognitive activity; therefore the primary schoolteacher’s most important task is the development of a set of cognitive universal learning skills that will effectively ensurethe development of the capability of successfully obtaining new knowledge and competences, that is, the ability to learn.We provided a list of basic universal skills for primary school students to master. The authors consider educational games,communication, and project activities ways of developing students’ universal learning skills. It is noted that universal learningskills become the basis for the formation of cognitive activity and independence of primary schoolchildren, their educationaland cognitive competence, which are the most important attributes of personally oriented learning at all levels of education.The authors of the article learned that the problem of the formation and development of primary schoolchildren’s universallearning skills is quite complicated and causes great difficulties even for experienced teachers. The source for such aconclusion was the analysis and processing of the results of the questionnaire conducted among students and in-serviceteachers. The contradiction between the importance of the development of primary school students’ universal learningskills when studying various disciplines and teachers’ insufficient methodical and organizational-pedagogical readiness wasrevealed. Future teachers’ readiness to facilitate primary schoolchildren’s educational processes is determined by cognitiveand activity criteria. The content of the didactic and methodological training of future teachers for the formation of primaryschool students’ universal learning skills is analyzed. In our opinion, this content consists of tasks for seminars and practicalclasses, solving situational problems, individual tasks, case methods, organization of students’ independent work, creation ofexercises and tasks for primary school students, and their assessment during pedagogical practice, etc.
