Serum Testosterone-Estradiol Ratio in Toxoplasma-Seropositive Infertile Men: A Prospective, Single-Center Study
Authors: Ragab Ahmed , Hamdy Doaa Ahmed , Ibrahim Shimaa Sayed
Published: March 2024

Background: The purpose of the current study was to compare the testosterone-estradiol (T:E2) ratio in Toxoplasma gondii seropositive infertile men with seropositive and seronegative normozoospermic controls.
Methods: Totally, 200 men with normal virilization, 100 with idiopathic infertility and 100 normozoospermic men, were included. Participants underwent medical history assessment, physical examination, semen analysis, testing for T. gondii IgM/ IgG, and estimation of serum T:E2 ratios. Statistical comparisons were done using t-test and Chi-square with p<0.05 significance level.
Results: Infertile cases were diagnosed with oligozoospermia (63%), oligoastheno-zoospermia (34%), and oligoasthenoteratozoospermia (3%). Regarding anti-Toxo-plasma IgG and IgM antibodies, among infertile men, 34 tested positive for IgG and 8 tested positive for IgM. Among cases tested positive for IgG antibodies, 13 (38.2%) had disturbed T:E2 ratios. Also, among the 12 IgG-positive controls, 5 (41.7%) had disturbed T:E2 ratios (p=0.834). However, only 2 out of the 83 seronegative controls (2.5%) had disturbed T:E2 ratios (p<0.001). Furthermore, 6 out of 8 IgM-positive cases had altered T:E2 ratios, compared to 3 out of 5 IgM-positive controls (p=0.568) and 2 out of 83 seronegative controls (p<0.001). The T:E2 ratio was significantly lower (8.68±1.95) among IgM-positive and higher (13.04±3.78) among IgG-positive cases when compared to seronegative controls (10.45±0.54) (p<0.001). There were no significant differences in T:E2 ratios between infertile men with positive IgM or IgG serology and the control group with the same serology.
Conclusion: A substantial number of infertile men with toxoplasmosis showed disrupted T:E2 ratios, highlighting the significance of anti-T. gondii-IgG testing in individuals with abnormal ratios.

Authors: Sharami Seyedeh Hajar , Milani Forozan , Kabodmehri Roya , Naghdipour Misa , Isaabadi Azade Mahmoudi , Haghparast Ghadim-Limudahi Zahra
Published: March 2024

Background: Fetal distress (FD) is one of the most frequent causes of emergency cesarean section (CS) due to the insufficient uteroplacental blood supply during labor. There is a theory that Sildenafil citrate (SC) may improve the uteroplacental blood supply and decrease fetal hypoxia and FD.
Methods: In a randomized double-blinded clinical trial, a total of 208 low-risk sub-jects who met our stringent inclusion criteria were randomly assigned into two groups: the Sildenafil citrate group (n=104) and the placebo group (n=104). These participants were referred to our referral gynecology and obstetrics department for delivery between July 2022 to September 2022. The SC group received oral SC at a dose of 50 mg every 6 hr, up to a maximum of three times. The final maternal-fetal-neonatal results were recorded and all data were analyzed using SPSS version 23.
Results: The mean age of mothers was 28.98±5.6 years and 120 cases were primi-gravid (57.7%). Out of a total of 208 pregnant subjects, 168 subjects delivered through normal vaginal delivery (80.8%) and 40 cases underwent emergency CS (19.2%). The number of NVD in Sildenafil group was significantly more than place-bo group (87.5% vs. 74%) and SC decreased the rate of emergency CS to 87.5% (RR=2.46%, 95%CI 1.19-5.08). Also, SC decreased the rate of FD to 53.8% (RR= 2.83%, 95%CI of 1-8.24).
Conclusion: The results showed that SC can effectively decrease the rate of emer-gency CS and FD during labor.
Evaluating the Plausibility of Euploid Embryos Transfer on Day-5 by Reanalysis of Day-3 Single Aneuploid Embryos: A Case Series
Authors: Bazrgar Masood , Kariminejad Roxana , Eftekhari-Yazdi Poopak , Gourabi Hamid
Published: March 2024

Background: During preimplantation development, single aneuploidies are more commonly tolerated than complex aneuploidies. Some studies have reported that blastocysts with aneuploid karyotypes on Day-3 embryo biopsy can exhibit a normal karyotype on Day-5 rebiopsy, suggesting that single aneuploidies may have a higher likelihood of presenting a normal karyotype on Day-5. The purpose of the current study was to assess the benefit of reanalyzing the karyotypes of Day-3 single aneuploid embryos on Day-5.
Methods: Day-3 and Day-5 biopsies of preimplantation embryos were subjected to array comparative genomic hybridization (aCGH). A proof of concept case series study was conducted involving 13 Day-5 embryos from 4 couples across 3 ART centers, collected between October 2019 and June 2020. Each center provided one normal embryo and 3-4 embryos with single aneuploidy based on Day-3 aCGH results. The karyotype of each Day-5 embryo was compared with its corresponding Day-3 karyotype.
Results: Among the 10 embryos with single aneuploidy on Day-3, 3 (30%) exhibited discordant karyotypes on Day-5, while the remaining 7 single aneuploid embryos and 3 normal embryos maintained the same karyotype from Day-3 to Day-5. None of the Day-3 single aneuploid embryos displayed a normal karyotype on Day-5.
Conclusion: Contrary to previous reports suggesting the potential correction of single aneuploidies in some embryos, the findings of this study did not support such a possibility in the analyzed embryos. Genomic reanalysis of Day-3 single aneuploid embryos on Day-5 does not appear to be a reliable method for identifying euploid embryos suitable for transfer.
Successful Treatment of Sperm DNA Fragmentation Through Ayurveda Rasayana Therapy: A Case Study
Authors: Bendale Vineeta , Chaganti Sreelakshmi , Pandav Rutuja , Pawar Deepali
Published: March 2024

Background: Sperm DNA fragmentation (SDF) can affect fertilization rate and embryo development, making it a useful measure for assessing male fertility. Available evidence supports the association between high sperm DNA fragmentation and poor outcomes, with regard to natural conception. Several treatment options are being adopted with varying degrees of success. Some of the commonly used treatment options are the intake of oral antioxidants, varicocele repair, and techniques like micro-manipulation-based sperm selection and use of testicular sperm for intracytoplasmic sperm injection.
Case Presentation: Studies have shown that around 29% of couples depend on complementary and alternative medicine (CAM) modality for the treatment of infertility. However, there is a lack of substantial evidence regarding its efficacy in treating various aspects of infertility in couples. The current case report is about a 44 year-old male patient with infertility, who has a known diagnosis of sex chromosome abnormalities. Meanwhile, the SDF study reports indicated the presence of chromosomal abnormalities. This patient was treated exclusively with Ayurveda therapy aimed towards qualitative improvement in reproductive tissues (Shukra Dhatu as per Ayurveda). Patient was assessed periodically for changes in chromosomal abnormality. After four months of treatment, the evaluations demonstrated the presence of completely normal chromosomes.
Conclusion: This case study indicates the potential of Ayurveda therapy in treating cases of male infertility caused by DNA fragmentation. Furthermore, observations and systematically designed clinical trials are warranted to establish a stronger level of evidence before making further clinical recommendations.

Examining Project Schools from the Perspectives of Teachers
Authors: Akman Saim , Gürlen Eda
Published: March 2024

Project schools were first introduced in 2014 with the approval of the Ministry of National Education. Between 2014-2018, there were a limited number of project schools. However, with the change in the high school entrance system in 2018, all the schools accepting their students with high school entrance exam transformed into project schools. This study aims to introduce and evaluate Project Schools, a new type of high school in an education system that already has many kinds of high schools, according to teachers’ views. The present study was conducted through a case study, a qualitative research method. 35 teachers of different branches working in four different kinds of project schools located in the central districts of Konya, İstanbul, Antalya, and Adıyaman participated in the study. Data were collected through semi-structured interviews and analyzed through descriptive analysis. At the end of the study, it was found that teachers have positive thoughts towards project schools. On the other hand, they think project schools have certain operational problems. It was also revealed that the aim of the project schools and the expectations from teachers working in these schools are not clear, that the teachers are expected to do extra work that is not stated in their job definition, that the teacher selection process is obscure and must be done according to objective criteria including central exam. The teachers also state that the curriculum of these schools needs to be different from others and must be suitable for their type and characteristics.
Life course studies – conceptual and methodological approaches and solution
Authors: Andreenkova Anna
Published: March 2024

Studies of the life course address the fundamental issue of social sciences – understanding the social change, its directions, reasons and perspectives, the interaction of micro- and macro levels of social reality. Studies of life course developed independently in different social sciences and scientific traditions cover a broad range of topics, issues and methodological approaches. These variety of studies were grouped into few major research frameworks: psychological within the studies of personality development; longitudinal sociological focused on life course of different cohorts and comparative studies of generations, social groups, countries and regions; domain-based – studies of trajectories in different life domains; demographic studying the timing of life events; studies of stability and transformation of values and biographical research. The multiple methodological approaches to study the life course are suggested to group in two main categories – concurrent and retrospective which differ by the time distance between the occurrence of an event and the reporting about the event. Concurrent approach is characterized by relatively high reliability of the measurement, but low flexibility in selecting research indicators, long time for the organization of data collection and large financial investments. Retrospective approach provides high flexibility in organization and design of the survey, allows free selection of indicators to test research hypotheses, but the reliability of the data is hampered by the memory errors and context effect. None of these approaches alone can satisfy the needs and requirements of studying the life course and collecting dynamic multi-level data. The possible solution is to design and test the multimodal approach combining the advantages of different research methods and mitigating their drawbacks. The new long-term longitudinal project “Life course, values and expectations of the generation of 1990s” (G90) included the test of an autobiographical method of data collection for random samples of the general population in quantitative design. The testing revealed high sensitivity of the method to the format (handwritten, printed or oral), high differentiation between respondents in completeness of information and the selection of events included in the autobiography. Supplementing autobiographies by in-depth interviews increased the data standardization, completeness and comparability. The drawbacks of this method found during the survey are high demand for resources for data analysis, individual approach to each autobiography, low respondents’ cooperation in highly demanding tasks, and ethical issues. The future of the life course studies can be found in the convergence of different research frameworks, multidisciplinary research projects, and the application of mixed-model integrated methodology.
Health behavior of young people: formation of typological attributes using the sentence completion method
Authors: Tatarova Galina , Chirkova Anna
Published: March 2024

The article actualizes the problems of typological analysis of young people according to character of health behavior, among them the issues of the formation of typological attributes are particularly highlighted. These are the theoretical constructs; characteristics on the basis of which the respondent is assigned to one or another typological group – the carrier of a certain social type. Various indicators of health behavior claim to be typological attributes. Their choice depends on many factors: on the specifics of the population being studied, on the basis of the typology, on the purpose for which the typological analysis is carried out, on the accumulated experience of research practices in using indicators, etc. The article presents the results of an exploratory research devoted to the study of young people’s representations about health behavior. The initial methodological premise was that the heuristic potential of indicators of health behavior as typological attributes in different groups of young people is different. The plausibility of this premise was confirmed in the process of analyzing text data obtained by the sentence completion method. Based on the construction of pyramids of generalizations (according to a survey of three age groups of young people), the structural elements of the image of “health behavior” (elementary justifications, elements, components) were identified, and the dominant elements and components were identified. As a result, assumptions have been made about the adequacy of certain methodical solutions in the formation of typological attributes.

Published: March 2024

Sclerotinia stem rot caused by Sclerotinia sclerotiorum (Lib.) de Bary is the most damaging disease and has been recorded in rapeseed-mustard cultivating nations of the world. It is more common and severe in temperate and sub-tropical regions during cool and wet seasons, although it may also be found in some semi-arid regions where conditions seem unfavourable for disease development. Botanical extracts are used as fungicides to control fungal growth and detection of new antifungal compounds which have no side effects on the environment or animal health. The evaluation of effectiveness of different phytoextracts were carried out through food poisoning techniques. Application of phytoextracts through food poisoning technique significantly reduced the myceliogenic growth of Sclerotinia sclerotiorum. Allium sativum registered maximum percent of mycelial inhibition of S. sclerotiorum, followed by Citrus lemon, A. indica, M. koenigii and A. cepa. Concentration wise, greater myceliogenic inhibition was observed in 15% fallowed by 10% and 5% phytoextract containing petri plates. Absolute mycelial inhibition was observed in A. sativum (15 and 10 % concentrations) treated plates. On the other hand, least efficacy of the phytoextract was observed in 5% A. cepa treated plate. The current in vitro studies of botanicals mycelial growth of S. sclerotiorum revealed that phytoextracts are an important component in crop disease management.

Published: March 2024

Arnavutluk’ta 14. yüzyılın sonlarında başlayan Osmanlı hâkimiyeti 1912 yılına kadar devam etmişti. Belirtilen tarihler arasında bu topraklarda birçok kilise inşa edilmişti. Özellikle Tanzimat ve Islahat Fermanlarının ardından kiliselerin inşa ve onarım faaliyetlerinin hız kazanmış olduğu gözlenmektedir. Osmanlı Devleti’nde Islahat Fermanı’nın ilanına kadar İslam hukuku çerçevesinde yeni kilise ve havraların inşası yasaklanmış ancak mevcut ibadethanelerin önceki ölçülerini aşmamak kaydıyla aslına uygun bir şekilde tamirine sultanın onayı doğrultusunda izin verilmişti. Tamir esnasında belirtilen kurallara riayet edilmediği veya kiliselerin izinsiz bir şekilde inşa edildiği durumlarda mabetler yıkılabilmekteydi. İnşa ve onarım faaliyetlerinde her ne kadar İslam hukuku esas alınsa da özellikle Balkanlarda Islahat Fermanı öncesinde yeni kiliselerin inşa edildiğine dair veriler mevcuttur. Ancak bu kiliselerin hangi şartlar altında inşa edildikleri bilinmemektedir. Cumhurbaşkanlığı Osmanlı Arşivi’ndeki belgelerin değerlendirildiği bu çalışmada Osmanlı Devleti’nin gayrimüslim ibadethaneleri konusundaki resmi politikalarına değinilerek bu politikaların Ergiri sancağında nasıl uygulandığı ortaya konulmaya çalışılacaktır.
Integrated anti-electronics for positron annihilation spectroscopy
Authors: Guatieri Francesco
Published: March 2024

Imaging the features of a sample using Positron Annihilation Spectroscopy (PAS) is currently achieved by rastering, i.e. by scanning the sample surface with a sharply focused positron beam. However, a beam of arbitrary shape (sculpted beam) would allow the application of more versatile single-pixel imaging (SPI) techniques. I introduce the design of a microelectronic device employing a 2D array of Zener diodes as an active positron moderator, capable of sculpting positron beams with 6µm resolution. The re-emitted positrons are accelerated towards the sample through a miniaturised electrostatic lens system and reaching 100nm resolution. The fast switch-on (90ps) and switch-off (250ps) time of the device would enable state-of-the-art positron annihilation lifetime spectroscopy (PALS) and PAS imaging with high spatial and temporal resolution.

Published: March 2024

In this study, organic matter distributions and concentrations at various stages of an urban wastewater treatment plant in Hefei, Eastern China, were analyzed from November 2022 to June 2023 using UV-Vis absorption and three-dimensional fluorescence spectroscopy. Six components identified via excitation-emission matrix and PARAFAC analysis revealed that components related to tryptophan (components 1, 3, and 6) had strong correlations with COD concentrations, with Pearson correlation coefficients of 0.656, 0.447, and 0.674, respectively. Analysis of fluorescence and UV-Vis absorption parameters indicated a reduction in organic matter content, increased humification, and a shift from exogenous to endogenous organic substances throughout the sewage treatment process. Notably, the humification index showed the highest correlation with COD levels (-0.834). On this basis, Utilizing Monte Carlo-Uninformative Variable Elimination-Partial Least Squares (MC-UVE-PLS) for characteristic wavelength extraction from normalized fluorescence and absorption spectra, a COD characteristic fusion spectral analysis model was developed. The results show that there is a good agreement between COD concentrations obtained based on feature fusion spectral analysis and COD true values obtained by the potassium dichromate method. The coefficient of determination between COD predicted values and the true values in the testing set reached 0.9725, and the root mean square error was only 10.51 mg/L. These findings suggest the efficacy of using UV-Vis absorption and three-dimensional fluorescence spectroscopy for direct COD tracking and detection in wastewater treatment processes without any pretreatment.
MLTU: Mixup Long-Tail Unsupervised Zero-Shot Image Classification on Vision-Language Models
Authors: Jia Yunpeng , Ye Xiufen , Mei Xinkui , Liu Yusong , Guo Shuxiang
Published: March 2024

Vision-language models, such as Contrastive Language-Image Pretraining (CLIP), have demonstrated powerful capabilities in image classification under zero-shot settings. However, current Zero-Shot Learning (ZSL) relies on manually tagged samples of known classes through supervised learning, resulting in a waste of labor costs and limitations on foreseeable classes in real-world applications. To address these challenges, we propose the Mixup Long-Tail Unsupervised (MLTU) approach for open-world ZSL problems. The proposed approach employed a novel long-tail mixup loss that integrated class-based re-weighting assignments with a given mixup factor for each mixed visual embedding. To mitigate the adverse impact over time, we adopted a noisy learning strategy to filter out samples that generated incorrect labels. We reproduced the unsupervised results of existing state-of-the-art long-tail and noisy learning approaches. Experimental results demonstrate that MLTU achieves significant improvements in classification compared to these proven existing approaches on public datasets. Moreover, it serves as a plug-and-play solution for amending previous assignments and enhancing unsupervised performance. MLTU enables the automatic classification and correction of incorrect predictions caused by the projection bias of CLIP.

Masyarakat memiliki hak untuk tahu tentang informasi terkait berbagai macam bahan pangan yang dipakai dalam sebuah produk pangan. Bahan pangan industri dalam skala rumah tangga yang beredar masih banyak yang mengandung bahan kimia yang berbahaya dan belum tentu aman untuk dikonsumsi yang secara umum beredar bebas di masyarakat. Masyarakat memiliki hak untuk tahu tentang informasi terkait berbagai macam bahan pangan yang dipakai dalam sebuah produk pangan. Penelitian ini menggunakan pendekatan penelitian yuridis normatif. Hasil dari penelitian yang dilakukan dapat disimpulkan bahwa pelaku usaha industri rumah tangga tidak mencantumkan semua informasi terkait dengan bahan pangan pada label yang digunakan khususnya untuk bahan tambahan pangan karena kendala SPP-PIRT dan pengaturan label. Konsumen hanya mengetahui bahan yang sudah dikenal secara umum, namun tidak dengan campuran bahan kimia apa saja yang dipakai serta tidak mengetahui secara presisi jumlah besaran campuran bahan tersebut pada makanan atau minuman yang dikonsumsi. Konsumen tidak mengetahui bagaimana pengolahan serta alat yang digunakan belum tentu memenuhi standar higienitas.

Background

In 2023, the United States experienced its highest- recorded number of suicides, exceeding 50,000 deaths. In the realm of psychiatric disorders, major depressive disorder stands out as the most common issue, affecting 15% to 17% of the population and carrying a notable suicide risk of approximately 15%. However, not everyone with depression has suicidal thoughts. While “suicidal depression” is not a clinical diagnosis, it may be observed in daily life, emphasizing the need for awareness.

Objective

This study aims to examine the dynamics, emotional tones, and topics discussed in posts within the r/Depression subreddit, with a specific focus on users who had also engaged in the r/SuicideWatch community. The objective was to use natural language processing techniques and models to better understand the complexities of depression among users with potential suicide ideation, with the goal of improving intervention and prevention strategies for suicide.

Methods

Archived posts were extracted from the r/Depression and r/SuicideWatch Reddit communities in English spanning from 2019 to 2022, resulting in a final data set of over 150,000 posts contributed by approximately 25,000 unique overlapping users. A broad and comprehensive mix of methods was conducted on these posts, including trend and survival analysis, to explore the dynamic of users in the 2 subreddits. The BERT family of models extracted features from data for sentiment and thematic analysis.

Results

On August 16, 2020, the post count in r/SuicideWatch surpassed that of r/Depression. The transition from r/Depression to r/SuicideWatch in 2020 was the shortest, lasting only 26 days. Sadness emerged as the most prevalent emotion among overlapping users in the r/Depression community. In addition, physical activity changes, negative self-view, and suicidal thoughts were identified as the most common depression symptoms, all showing strong positive correlations with the emotion tone of disappointment. Furthermore, the topic “struggles with depression and motivation in school and work” (12%) emerged as the most discussed topic aside from suicidal thoughts, categorizing users based on their inclination toward suicide ideation.

Conclusions

Our study underscores the effectiveness of using natural language processing techniques to explore language markers and patterns associated with mental health challenges in online communities like r/Depression and r/SuicideWatch. These insights offer novel perspectives distinct from previous research. In the future, there will be potential for further refinement and optimization of machine classifications using these techniques, which could lead to more effective intervention and prevention strategies.

BACKGROUND

Dry Eye Disease (DED) is a prevalent eye condition characterized by abnormalities in tear film stability. Despite its high prevalence, diagnosing DED remains challenging, primarily due to the invasive nature of most diagnostic tests, such as the Tear BreakUp Time (TBUT).

OBJECTIVE

The aim of this paper is to propose a novel smartphone-based methodology for non-invasive screening of Dry Eye Disease.

METHODS

In this work, we propose DEDector, a low-cost, smartphone-based automated Non-Invasive Break-Up Time (NIBUT) measurement methodology for DED diagnosis. Utilizing a 3D-printed placido ring attachment on a smartphone’s camera, DEDector projects concentric rings onto the cornea, capturing a video for subsequent analysis using our proposed video processing pipeline to identify tear film stability.

RESULTS

We conducted a real-world evaluation on 46 eyes from 23 patients, comparing the performance of DEDector against the traditional Fluorescein Break-Up Time (TBUT) method. Our results indicate a sensitivity of 77.78% and specificity of 82.14% for DEDector, outperforming the TBUT-based approach (Sensitivity = 72.22%, Specificity = 75%)

CONCLUSIONS

DEDector may be used for large-scale and point-of-care screening of Dry Eye Disease, due to its low cost, portability, and effectiveness in detecting Dry Eye Disease.

BACKGROUND

In recent years, with the continuous development of mobile communication technology, the large-scale popularization of intelligent mobile devices such as cell phones and tablet computers has prompted the emergence of mobile medical service platforms.With the aging trend of chronic diseases in China becoming more and more obvious, the public's demand for health information and the degree of portability is getting higher and higher, making it a certain requirement for the development and updating of mobile medical service platforms.Therefore, it is crucial to analyze the advantages and shortcomings of the current Chinese mobile medical and provide constructive suggestions.

OBJECTIVE

To comprehend the development of mobile medical service platforms in domestic general hospitals, study and compare the characteristics of various platforms, and make constructive recommendations for enhancing the quality of mobile medical services.

METHODS

Taking the mobile medical service platforms such as the latest version of mobile APP or hospital WeChat public number currently applied by the top 50 hospitals in the Fudan University 2022 Comprehensive Ranking of Chinese Hospitals as the object of study. Adopting the network survey method and literature analysis method, we construct a preliminary evaluation indicator system of the user interface containing three first-level indicators, 13 second-level indicators, and 19 third-level indicators of visual design, interaction design, and technological development, as well as a service function evaluation index system consisting of four modules, namely, service items, information content, health education, and evaluation system, to evaluate the current status of the functions of the mHealth service platform.

RESULTS

China's general hospital mobile medical service platform meets the requirements for a basic user interface design and offers a basic booking function in its service function. At the same time, the majority of hospitals focus on expanding their basic services and implementing relevant innovation. Since China's smart hospital is still in its early stages of development, construction took comparatively little time, homogenization between platforms is more evident, and platform construction innovation still needs to be further enhanced.

CONCLUSIONS

The construction of mobile medical service platform in domestic hospitals is still in the initial stage, and the key to the development of mobile medical service is to improve the user experience, perfect the functional modules, take into account the users of different age levels and focus on privacy protection.
