Authors: Alp Hayrullah , Dülger Özlem , Şencan Fatmagül
Published: November 2024

Aim: Fetal echocardiography is an effective screening tool for the detection of cardiac anomalies. The aim of this study is to evaluate risk groups of pregnant women, to determine congenital heart diseases in each group and to find the prevalence of cardiac anomalies in our region.
Materials and Methods: All pregnant women referred for fetal echocardiography from January 2023 and September 2024 were included in the study.
Results: A total of 387 pregnant women underwent fetal echocardiography of which 136 were low risk group and 251 were high risk group. The mean ages of patients were 27.43±1.37 and 28.54±5.45 years, respectively. Maternal diabetes (13.17%), dysrhythmia (5.42%) and history of previous child or fetus with extracardiac anomaly (8.53%) were the most common reasons for referral in the high-risk group. While ventricular septal defect was the most detected congenital heart disease in low risk group; hypoplastic left heart syndrome (1.20%) and pulmonary atresia/hypoplasia (1.20%) were the most detected cardiac anomalies in high risk group. The prevalence of congenital heart diseases in our series was found to be 2.94% and 6.37% in the low-risk and high-risk pregnancies respectively while the overall prevalence was 5.16%.
Conclusion: Fetal echocardiography is a very useful technique when performed by experienced individuals with sufficient time. Dedicated cardiac screening should be part of the routine anomaly scan. Also, detailed fetal echocardiography should be performed in all pregnant women who were in low or high risk groups.

Published: November 2024

Aim: The objective of this study was to differentiate between benign and malignant sinonasal tumors using magnetic resonance imaging (MRI)-based texture analysis features.
Materials and Method: Histopathologically proven benign or malignant sinonasal tumor patients were included in the study from MRI examinations performed between January 2013 and December 2020. Inclusion criteria included a tumor size of at least 1 cm and preoperative magnetic resonance imaging with axial T1W, axial fat-suppressed T2W, and axial T1W postcontrast sequences. After the images were transferred to a dedicated workstation, texture analysis calculations were performed. Differences between benign and malignant groups were compared.
Results: The mean age of 37 patients (8 female, 29 male) included in the study was 50.8 ± 21.9 years. In our study, we found no statistically significant difference between malignant and benign sinonasal tumors in nine tissue analysis parameters obtained by MRI.
Conclusion: MRI-based texture analysis needs identical MRI protocols for evaluating tumors. MRI-based texture analysis is not a useful diagnostic tool to discriminate between benign and malignant sinonasal tumors when specific pathologic types are not selected and scanning protocols are not identical.

This study examines the relationships between a country’s governance indicators and
bank financial stability and the moderating effect of a country’s income level on those
relationships. This study uses unbalanced country-level panel data of 110 countries
from the World Bank from 2010 to 2021. Ordinary least squares (OLS) estimation fails
to pass heteroskedasticity, first-order autocorrelation, and cross-sectional
dependence tests. To ensure robustness in the estimation, this study uses panel
corrected standard error (PCSE) estimation model for the direct and moderating
effect analysis. The findings show that banks’ financial stability mostly depends on
bank-specific factors, and better country governance enhances bank financial
stability. This study also finds that a country’s high-income, upper-middle-income,
and lower-middle-income moderate the relationships between a country’s
governance indicators and the bank’s financial stability. This finding will help
bankers, regulators, and policymakers adopt effective governance policies to
strengthen the financial stability of the banking sector. Unlike previous studies, this
study overcomes the limited regional context and scope of measuring the
relationships between a country’s governance indicators and a bank’s financial
stability and also measures the moderating effect of the country’s income level on
the same
Advantages of EEG monitoring in education

Published: November 2024

Affordable, portable, and easy-to-use devices, as well as computer programs that allow the quantitative analysis of EEG signals, provide the opportunity for wide-ranging educational applications of EEG. However, the use of EEG data is complicated by the presence of significant individual differences in resting activity; therefore, this technology is not suitable for analyzing educational processes on its own. However, when used together with other methods, it could provide valuable data on learning-related brain activity. In our study, we used the Emotiv EPOC EEG headset and monitored brain activity during closed- and open-eye relaxation, reading, and arithmetic calculation. We used the Fourier Transform (FFT) to analyze the spectral content of the EEG signal, determined the power of the theta, alpha, and beta EEG bands, and then calculated the attention, engagement, and cognitive load values for each task. Participants also solved a test related to the tasks, evaluated their performance, and filled out a questionnaire about their impressions of the measurement. We made our conclusions by combining the data from the EEG, the test, and the questionnaire results. We found an increase in the alpha power related to tiredness, increased attention during reading, and high cognitive load during calculation, especially when the result was correct. Participants diagnosed with dyslexia showed lower alpha peak frequency during open-eye relaxation and increased theta activity during reading. Although they needed more time to complete the reading task, their test results were similar to the results of the control group. Our results suggest several possible usage of EEG in education. It enables the continuous monitoring of alertness, can detect fatigue, and helps keep task difficulty at an optimal level. However, the beta theta ratio used in this study to determine attention level does not seem suitable for monitoring sustained attention. EEG can also give us useful insight into the performance of students with special needs, helping teachers provide adequate tasks and guidance.
A digitális oktatás könyvtárpedagógiai vonatkozásai – hagyományos képzés vs. valóság
Authors: Czeglédi László , Zentai Péterné
Published: November 2024

Az előadás a könyvtárostanár képzés gyakorlati tapasztalatait és digitális korlátait veszi számba az online oktatás bevezetésétől a változások kialakulásáig (szerzői jog, fizikai korlátok stb.). Bemutatja, hogy milyen kényszer szülte megoldásokat kellett találni az új helyzetben, újra kellett gondolni az online is megvalósítható könyvtárhasználattal kapcsolatos tartalmakat, hiszen nem minden ültethető át az online térbe. Gyors reagálásként újabb IKT-eszközök, online felületek, alkalmazások használatát kellett megtanulnia hallgatónak, tanulónak, szakvezetőnek egyaránt, illetve a korábbi ismereteket kellett felfrissíteni. Kihívásként jelentkezett, hogy meg kellett tanulni az online óratervezés módszertanát, s nem utolsósorban le kellett küzdeni az online platform miatt minden szereplőben kialakult szorongásokat (emberidegen környezet, távolságtartás, a személyes kommunikáció hiánya). A könyvtárostanár képzés esetében fokozottan megjelennek ezek a problémák a fizikai háttérből való kiszakítottság miatt. Létezhet-e könyvtárostanár képzés könyvtár és könyvek nélkül? A tanulságok megfogalmazása után felvetődik a kérdés: mi marad meg a régiből és mi alakul át? Mit jelenthet a jövőben az interaktív könyvtárpedagógia a hétköznapokban? Mi történjék, ha nincs lehetőség bevinni a könyvet és a könyvtárt az órákra – vigyük be az órát a könyvtárba, akár virtuálisan is! Elkezdtük a hagyományos órák, óratervek módszertanát átültetni e-learning felületre ill. képzésekre (kísérő módszertani szeminárium feladataként). Megannyi kérdés válaszra, megoldásra vár, mert digitális oktatás van, ettől kezdve lesz, létezik, számolni kell vele a könyvtári területen működő intézményeknek is, akik eddig elsősorban csak a fizikai megjelenés és tapasztalat módszereivel dolgoztak.
Big Data-alapú korpuszok alkalmazása a német mint idegen nyelv oktatásában
Authors: Mészáros Attila
Published: November 2024

A Web 2.0-alapú technológiák elterjedésének köszönhetően az internet egy olyan virtuális közösségi térré vált, ahol a korábban alapvetően passzív fogyasztók hirtelen aktív tartalomgyárosokká válhattak. Ez ma elsősorban a közösségi média kontextusában tapasztalható. Ennek a "közösségivé válásnak" egyik lényeges eredménye, hogy a felhasználók folyamatosan óriási mennyiségű olyan tartalmat generálnak, amelyek különösebb akadályok nélkül felhasználhatók az online felületeken zajló kommunikáció kutatására, pl. a diskurzuselemzésen belül. A diskurzusnyelvészet, ill. a diskurzuselemzés innovatív és integratív tudományos diszciplínaként számos más tudományágból merít, ill. nyújt számukra új ismereteket. Ugyanakkor kevesebb figyelmet kap az a kérdés, hogy mennyiben használhatók fel a diskurzusok az oktatáson belül didaktikai eszközként. Jelen tanulmány keretében az a kérdés kerül körbejárásra, hogy mennyiben használhatók fel a diskurzusok, mint Big Data alapú korpuszok a német mint idegen nyelv oktatásán belül.
Okostelefonok az osztályteremben
Authors: Szegiová Cyntia
Published: November 2024

A tanulmány a tantermekben történő okostelefon-használat vizsgálatával foglalkozik egy összehasonlító vizsgálat eredményeinek tükrében. Célja, hogy az általános iskolások, középiskolás diákok és egyetemi/főiskolai hallgatók körében végzett felmérés alapján bemutassa az okoseszközök oktatásban való használatának változásait a 2020-2022 közti pandémiás időszak során. A vizsgálat abból a feltevésből indul ki, hogy bár az okoseszközök – így az okostelefonok – gyakorlatilag évek óta mindennapjaink elengedhetetlen részeit jelentik, azok alkalmazása az oktatásban a Covid-járvány előtt kevésbé volt rendszeres és tervezett, sokkal inkább véletlenszerű. E téren hozott alapvető változást a pandémiás időszak, mikor az online, esetleg a hibrid oktatásra való áttérés az oktatás minden résztvevőjét rákényszerítette alternatív megoldások bevetésére. Ennek megfelelően az okostelefonok használata is – legalábbis részben – átértékelődött, hiszen azok sokoldalú mobil eszközként rendkívül optimálisan használhatók az oktatásban is. A tanulmány keretében egy először 2019-ben elvégzett, majd 2023-ban megismételt kérdőíves felmérés eredményei kerülnek bemutatásra és értelmezésre.

Kutatási irányok feltérképezése a múzeumok és könyvtárak tudásmegosztó szerepéről
Authors: Schmidtka Ildikó
Published: November 2024

A közoktatási intézmények, ugyanúgy, mint a múzeumok és könyvtárak is, alapvetően tudásszervezetek, meghatározó szerepük van a tudástranszferben (gondoljunk akár explicit, akár tacit tudásra). A rendelkezésükre álló hatalmas ismeretanyag birtokában a múzeumokban és könyvtárakban hatalmas kiaknázatlan potenciál rejlik ezek közoktatási felhasználását illetően, azonban ezek felhasználása a közoktatásban jelenleg csak korlátozottan valósul meg. Egy fontos cél lehet ezen a területen a múzeumok és könyvtárak tudásátadási szerepének erősítése, amelyben fontos szerepet kaphatnak a 21. századi digitális módszerek. Ebben az online digitális technológiák adta lehetőségek megalapozhatják és megerősíthetik az informális tanulási környezet szerepét és a közoktatás irányába történő alkalmazását egyaránt, hogy a közgyűjteményekben, a gyakorlat szempontjából lényeges ismeretanyag közoktatásba történő bevonása megtörténhessen. Egyben egy további fontos cél a múzeumokban és könyvtárakban eddig már eltérő módokon megvalósított szigetszerű megoldások integrálása és a közoktatás számára elérhetővé tétele a NAT figyelembevételével. Ezen cikk célja egyrészt, hogy az előzőkkel kapcsolatban bemutassa egy, a múzeumok és könyvtárak tudástranszfer szerepét támogató fejlesztés irányait, másrészt részletezze a tudástranszfer szerepüket vizsgáló kutatás kutatási irányainak, kutatási céljainak feltérképezését és a tervezett kutatás módszertanának részleteit. A kutatás elméleti és gyakorlati relevanciája nagymértékben hozzájárul a közoktatásba bevonható ismeretanyagok bővítéséhez, korszerű, digitális megoldások alkalmazásához, esetleges jó gyakorlatok feltérképezéséhez.
Interaktív hangoskönyvek az oktatásban
Authors: Ujhelyi Gábor
Published: November 2024

A hangoskönyvek oktatási alkalmazására már sok esetben tettek próbálkozásokat, azonban egyelőre nem épült be szervesen a módszerekbe. Annak ellenére, hogy létrejöttük nem újkeletű, kevés fejlődésen mentek keresztül, azonban az utóbbi évek technológiai fejlesztései számos új alkalmazási, bővítési lehetőséget nyitnak meg. Az írott ismeretanyagok hangon keresztül befogadhatóságához több út vezet. Ebből a megközelítésből a figyelem középpontjába elsősorban a tudományos, ismeretterjesztő, szak- illetve tankönyvek kerülnek. Ebben az esetben arányaiban kisebb jelentősége van az audio előadás módjának, stílusának, hangszínének, dominánsabb az információ jól érthető átadásának szándéka, aminek köszönhetően a maga hiányosságaival együtt is van létjogosultsága a gépi felolvasásnak, beszédszintézisnek. Kutatásom célja annak igazolása, hogy a jelenleg széles körben elérhető és egyre fejlettebb nagy nyelvi modellek, valamint felhő szolgáltatásokon keresztül elérhető text-to-speech (gépi felolvasó) és speech-to-text (leiratozó) megoldások segítségével megvalósítható, hogy egy digitálisan rendelkezésre álló írott könyv automatikusan előállhat hangoskönyvként úgy, hogy ne csak felolvastatható és meghallgatható, de gépileg interaktívvá tehető, öszszefoglaltatható, magyaráztatható és kérdezhető legyen, ami nagy mértékben hozzájárulhat ahhoz, hogy az oktatási anyagok az auditív tanulótípusokhoz is közelebb kerüljenek és segítsék az anyag megértését és elmélyülését, valamint segítséget nyújthat az olvasási nehézségekkel küzdő tanulók számára. A kutatás megvalósítása során a jelenleg elérhető fejlett felhő alapú és helyben futtatható nagy nyelvi modellek tulajdonságait, finomhangolhatóságát, különböző méretű dokumentumok feldolgozhatóságát és azokról egy minta alkalmazásban írott vagy szóbeli formában természetes nyelven feltett kérdésekre általuk adott válaszok tartalmi validitását vizsgálom.

Authors: Ongün Pınar , Goncekli Busranur
Published: November 2024

Objective: To determine the learning needs of surgical patients via the internet/social media after discharge.

Methods: This descriptive study's population comprised all patients discharged from the surgical clinics of a university hospital after surgery between 12 December 2021 and 04 April 2022. A total of 180 patients participated in the study. Data were collected using a form created by the researchers and the Patient Learning Needs Scale.

Results: The mean age of the patients who participated in the study was 52.48±16.78 years; 67.22% were female, and 50.55% were primary school graduates. It was determined that patients obtained most of their information from the YouTube application (39.34%), and after surgery, they used social media since it offered more accessible access to healthcare professionals. 42.22% of the patients answered “undecided” to the question “Are internet/social media applications a reliable source for obtaining information about surgery?” The participants’ mean total score on the Patient Learning Needs Scale was 174.00±33.00, and the subscale with the highest importance level was considered skincare at 4.27 ±0.52.

Conclusion: Most discharged patients use the internet to seek information about their surgery. Their Patient Learning Needs Scale score was above average, and the highest subscale score was skincare. It is recommended that nurses working in surgical clinics consider the needs of patients when planning discharge education and provide them with reliable sources that can be accessed when needed.

Authors:   Student, Department of CSEAIML, Malla Reddy Engineering College, Maisammaguda, Secunderabad, Telangana, India, Velagala Sumanth Reddy , Srinivas U Mohan
Published: November 2024

Objectives: Evaluate the effectiveness of transfer learning with pre-trained CNNs for detecting diabetic retinopathy using a minimal dataset. Methods: Six pre-trained models (DenseNet201, ResNet152, VGG16, InceptionV3, MobileNet, and EfficientNetB0) were trained on 40 retinal fundus images each for training, validation, and testing. Models were evaluated over 5, 10, and 15 epochs, focusing on Test accuracy, Validation accuracy, and Validation loss. Findings: MobileNet achieved a Test accuracy of 70% at 15 epochs, consistently outperforming other models across all epochs. InceptionV3 initially performed well but was ultimately surpassed by MobileNet, which demonstrated stable and robust performance with limited data. These results suggest that MobileNet is highly effective in learning and generalizing features relevant to diabetic retinopathy detection, making it an optimal choice for use in resource-constrained settings. Novelty: This study highlights MobileNet's superior efficacy in diabetic retinopathy detection using minimal data, addressing an area that has been largely unexplored in existing literature.

Lock and Key Share Secret Sharing Scheme with Meaningful Shares for Grayscale Image and Color Image
Authors:   Department of Electronics & Communication Engg, Dharmsinh Desai University, Nadiad Gujarat, India, Rabari Dipak K , Meghrajani Yogesh K , Desai Laxmi S
Published: November 2024

Objectives: The proposed scheme aims to present a secret sharing scheme (2, m, n) with lock and key shares, including meaningful shares for all lock and key shares. Methods: To create m lock and n key shares, the secret image will be encrypted. To retrieve the secret information from the recipient, any one share from the lock and another share from the key shares are used. When both shares are selected from either lock shares or key shares, no partial information about the hidden image is recovered. Meaningful shares do not disclose any information on the privacy of the picture data. The secret image at the recipient can have lossless reconstruction with minimal computation. Findings: The performance analysis of a proposed minimally computational secret sharing approach shows the structural similarity index (SSIM) as 1 and correlation as 1 which yields a reconstructed image that is exactly the same as the secret image. Typically, the secret image is reconstructed from meaningless shares using Boolean XOR. However, because attackers believe that secret information is concealed in meaningless shares, these shares are susceptible to share security breaches. Therefore, meaningful shares will improve the security of the share image. Novelty: The scheme provides a two-tier security model with meaningful shares for the secret image formats like grayscale and color images.

Authors:   Bannari Amman Institute of Technology, Sathyamangalam, Erode, 638401, Tamil Nadu, India, Dhivya P , Vanithamani S , Malini M , Kanimozhi T
Published: November 2024

Objectives: The primary goal of this research is to improve the segmentation accuracy of Gastrointestinal (GI) tract images, addressing the challenges posed by complex anatomical structures, noise artifacts, and varying imaging modalities. The study aims to overcome the limitations of traditional techniques like thresholding and region growing, as well as mitigate the drawbacks of current deep learning-based models, such as high computational costs and overfitting. Methods: UW-Madison GI Tract Images are collected from the Kaggle repository. the proposed method introduces an Adaptive Edge-Guided Segmentation (AEGS) framework that integrates BifTransNet with enhanced edge detection and region-growing techniques. The model uses the batch size, epochs, and learning rate as parameters. This approach incorporates attention mechanisms, advanced boundary delineation, and regularization techniques to reduce overfitting while improving segmentation accuracy. The model is trained with regularization to optimize its performance, making it more robust and reliable. Findings: The experimental results show significant improvements, with the proposed AEGS framework achieving a segmentation accuracy of 98.6% and a training loss of 0.12. This marks a substantial enhancement in both robustness and reliability compared to traditional methods and existing deep-learning models for GI tract image segmentation. Novelty: The key innovation lies in the hybrid approach of combining deep learning (BifTransNet) with improved edge detection and region-growing techniques. This hybridization not only enhances segmentation performance but also addresses common issues such as overfitting and computational costs, setting a new benchmark in GI tract image segmentation.

A finite vector that represents the distances between a vertex and the vertices of an ordered subset is the metric representation of a vertex of a graph. is called a minimal resolving set if no suitable subset of provides distinct representations for every vertex of . The lowest minimal resolving set (in relation to its cardinality) has a cardinality that determines 's metric dimension. In case has independent vertices, it can be referred to as an independent resolving set (ir-set). The value of the independent resolving number for different classes of graphs is found and defined. In this study, we investigate the graph classes' independent metric dimension. Our results demonstrate the differences in independent metric dimensions throughout families of graphs.
«Il Fior di Battaglia» symbols: iconography of early XV century fencing treatise by Fiore dei Liberi
Authors:   Uzhhorod National University, Uzhhorod, Ukraine, Palii Liudmyla
Published: November 2024

Purpose. This article's purpose is the reconstruction of the creation context of the fencing treatise «The Flower of Battle» and renew some fragments from the Italian fencing master's life in the late 14th century - early 15th centuries with visual sources.

Methods. We have looked into three Italian manuscripts, using comparative, hermeneutic and prosopographic methods.

Results. The Renaissance fencing treatises is the popular research object for twenty years. The Italian material arts studies are based on the treatise of Fiore dei Liberi «The Flower of Battle». This source is an important part of modern European martial arts research and 15th century combat practices. An analysis of the sources (text, iconographic elements and archival materials) allows us to present several versions of the Italian master Fiore dei Liberi’s private and professional life. First of all, our attention pays on the ideas that contributed to the combat system structure in the treatise «Il Fior di Battaglia». The careful work with the symbols which are inside of manuscript structure allowed us to identify new details. It will help to better understand both the context of the text writing and its creation motivation for the author.

Conclusions. It is important to note the attempt to fill in the blanks only with help of visual sources requires additional reinforcement with writing sources. However, the investigation of such a plan allows us to expand the field for the successor fencing treatises. Also it introduces a new perspective on the well known facts and highlights those ones, which have been lost by attention of the previous researchers. The study about fencing masters personalities and the formation concept of martial arts allows us to better understand its place among 15th century military communities. It is possible to follow both the paths of all combat practices and the relations between the users of such an intellectual product as a fencing treatise through the social connections of the fencing master.

Authors: Anggraini Laelia Dwi , Agasa Octafita
Published: November 2024

The prevalence of caries shows a percentage of 90% in toddlers in Indonesia. Caries has a negative impact on the body development of toddlers. Through the right parenting style, it is considered to be possible to reduce the caries rate in children under five. This study aims to determine the effect of parenting style on toddler dental caries in Baki District, Sukoharjo Regency. Accordingly, this analytical observational research applied a cross-sectional approach. Samples were taken using a purposive sampling technique involving 111 toddlers and their parents in Baki District. Toddler dental caries was measured using the dmft index, and parenting style was measured by a questionnaire adapted and modified from The Parenting Styles and Dimensions Questionnaire (PSDQ). Process data with IBM SPSS version 20. Results show that the parenting style of most parents involved in this study was authoritative (47,7%), followed by authoritarian (28,8%), and lastly permissive (23,4%). The highest dmft index is found in toddlers raised by permissive parents (7,92). The average education level of mothers in the three parenting styles was at the high school level (65%). The majority of parents' income in a month is in the moderate category. The conclusion showed that parenting style had no effect on toddler dental caries in Baki District, Sukoharjo Regency.

Published: November 2024

Oxidative stress in the oral cavity, driven by an imbalance between free radicals and antioxidants, can lead to lipid peroxidation, as reflected by elevated malondialdehyde (MDA) levels in saliva. Proper oral hygiene, such as regular tooth brushing, is vital in mitigating oxidative damage. This study aimed to evaluate the effects of rambutan honey toothpaste with a color indicator on reducing oxidative stress in the oral cavity by measuring salivary MDA levels. This research was conducted using a laboratory experimental design, with saliva samples collected from students at the Faculty of Dentistry, Universitas Jenderal Achmad Yani. Participants were assigned to five groups: rambutan honey toothpaste with a color indicator (RHTCI), rambutan honey toothpaste without a color indicator (RHT), color-indicated toothpaste without honey (TCI), base toothpaste (BT), and distilled water (DW). The thiobarbituric acid reactive substances (TBARs) method was applied to assess MDA levels, and statistical analysis was conducted using Kruskal-Wallis and Mann-Whitney tests. The results showed a significant reduction in salivary MDA levels following the use of RHTCI (p = 0.0001). A notable difference was also found between RHTCI and TCI (p = 0.001), while no significant difference was observed between RHTCI and RHT (p = 0.190). These findings suggest that rambutan honey toothpaste with a color indicator effectively reduces salivary MDA levels, highlighting its potential antioxidant benefits.

Published: November 2024

Background: Polycystic ovary syndrome (PCOS) is a major cause of anovulatory infertility and affects 5-10% women of reproductive age. High serum anti-mullerian hormone (AMH) is associated with lack of ovulation in PCOS women. Combined oral contraceptives containing ethinylestradiol and drospirenone suppress androgen production and reduce AMH concentration which may optimize the women with PCOS for better response to ovulation induction. This study aimed to assess the effects of ethinylestradiol-drospirenone (EE-DRSP) and metformin combination as pretreatment for ovulation induction in polycystic ovary syndrome in comparison to metformin only pretreatment.
Methods: This was a randomized controlled trial conducted on a total 62 subfertile PCOS women having high serum AMH (≥5 ng/dl). They were randomly assigned into 2 groups. In group A 31 participants received EE-DRSP and metformin combination and in group B 31 participants received only metformin for 3 months. After 3 months the participants had ovulation induction with letrozole for 3 cycles. The outcome variables were the rates of ovulation and pregnancy.
Results: Ovulation rate per cycle was higher in group A than group B. Cumulative ovulation rate per participant was also 1.36 times higher in group A than B (100.0% versus 73.3%). Cumulative pregnancy rate was 1.91 times higher in combination group than metformin alone group (67.7% versus 35.5%).
Conclusions: Pretreatment with ethinylestradiol-drospirenone and metformin for three months before ovulation induction is more effective than metformin only in terms of higher ovulation and pregnancy rate in subfertile PCOS women.

Background: Ovarian cancer diagnosis is growing due to the prudent use of investigational methods. Imaging techniques and molecular biomarkers are the commonly used. A correct ovarian cancer staging assists gynecological oncologists in determining whether the patient required primary debulking surgery or neoadjuvant chemotherapy. The aim of the study was to evaluate the accuracy of CA-125 titre, USG of whole abdomen imaging and CT scan for diagnosis of ovarian malignancy.
Methods: A prospective, observational study was conducted Gynae Oncology Unit, Department of Obs and Gynae, Dhaka Medical College Hospital, Dhaka during January 2022 to December 2022. Total 96 patients who were diagnosed clinically as malignant ovarian tumor were included in the study.
Results: The sensitivity of malignant ovarian tumors by USG was calculated to be 89.4%, specificity was 76.7%, accuracy was 85.4%, PPV was 89.4%, and NPV was 76.7%. The validity of CA-125 in malignant ovarian tumors was demonstrated by calculating sensitivity of 75.8%, specificity of 90.0%, accuracy of 80.2%, PPV of 94.3%, and NPV of 62.8%. The sensitivity of malignant ovarian tumors by CT was calculated to be 90.9%, specificity was 86.7%, accuracy was 89.6%, PPV was 93.8%, and NPV was 81.3%. Using histology as the gold standard.
Conclusion: The results of this study demonstrate the superior diagnostic capabilities of two distinct imaging modalities (USG and CT) in determining the degree of malignant spread.

Published: November 2024

Background: Polycystic ovary syndrome (PCOS) is a multisystem disorder featuring reproductive issues and metabolic problems, with a global prevalence of 5-15%. PCOS is linked to infertility, oligomenorrhea, amenorrhea, and adverse pregnancy outcomes like miscarriage and gestational diabetes. Genetic factors contribute to its cause, and lifestyle changes can improve its metabolic and endocrine impacts, aiding in fertility. This study aimed to explore the association between PCOS and various pregnancy outcomes in infertile women by comparison with control group.
Methods: This cross-sectional analytical study was conducted at the department of obstetrics and gynecology (indoor and outdoor) in BSMMU, Dhaka from January 2021 December 2021. Along with ethical approval, the study involving 275 female participants selected via purposive sampling and categorized into two groups: case group (n=110) with PCOS and control group (n=165) without PCOS. Data collection included baseline demographics, blood samples, and IVF/ICSI outcomes.
Results: This study explored how polycystic ovary syndrome (PCOS) impacts pregnancy outcomes in infertile women undergoing their first IVF treatment. It included 275 participants. The case group's average age was slightly higher (p<0.001). The case group had lower BMI (p<0.001) and higher rates of primary infertility (p<0.001). Ovulatory disorders were more common in the case group (p<0.001). The case group exhibited higher fasting insulin levels (p<0.001). The case group had higher clinical pregnancy (p<0.001) and live birth rates (p=0.003) but higher early miscarriage rates (p<0.001).
Conclusions: PCOS negatively affects infertility and pregnancy, causing ovulatory issues, insulin resistance, and complications like gestational diabetes. Despite lower fertility and pregnancy rates, effective treatments can lead to live births comparable to non-PCOS women.

Published: November 2024

Background: Cervical is the most prevalent genital cancer, the second most frequent gynaecological cancer, and the second-highest rate of cancer-related death among Indian women. Cervical cancer is preventable because it has a prolonged preinvasive stage, effective cervical screening programs exist, and preinvasive lesions that can be treated.
Methods: The prospective observational study has been carried out on all women attending the (OBGY) OPD in GSVM medical college and hospital. 1000 women were selected for the study. Appropriate history was taken and the women were advised to undergo Papanicolaou (PAP) smear and were followed for reports and were further treated accordingly.
Results: As the number of risk factors increased, the higher the degree of lesions were observed in cervix. After being counselled for screening, 100% women agreed for PAP smear in which 71.5% of the women had normal results, 10.5% were diagnosed with cervicitis, 9.3% had vaginitis, 3.2% had an inadequate smear, 2.1% also had an inadequate smear, 1.3% had bacterial vaginosis, 1.0% had ASCUS, 0.8% had HSIL, and 0.3% showed reactive cellular changes. Following a cervical biopsy, 14.9% of the women in need of additional testing had a normal biopsy, and 24.3% had chronic cervicitis. Invasive carcinomas affected 16.2% CIN1, 2.7% CIN2, 1.4% CIN3, and 1.4% of CIN1. 10.8% of the individuals could not be reached for follow-up.
Conclusions: In our study we found that after counselling 100% women agreed for PAP smear and hence this shows that counselling is very important to create awareness regarding prevention of cancer. Multiple risk factors are associated with cervical cancer and awareness regarding it is necessary in general population to reduce the risk of cervical cancer.

Published: November 2024

Background: The aim of our study is to represent our experiences with non-descent vaginal hysterectomies (NDVH), the intraoperative and postoperative complications of NDVH, using suture less procedure and only energy sources like cautery, assess intra operative blood loss, operative time, risk of infection, post op hospital stay. The objective was to assess the outcomes of the safest and scar less method of hysterectomy i.e. NDVH, practised at a tertiary centre in one-year period of time.
Methods: This was a retrospective case study conducted in the department of obstetrics and gynaecology of NRI Medical College and Hospital, Mangalagiri, over a period of 12 months (October 2022 to October 2023). This includes 50 patients who underwent non-descent vaginal hysterectomy for benign indications with adequate vaginal access, with good mobility, without any suspected adnexal pathology and without uterine prolapse.
Results: All 50 cases were studied retrospectively. None of them had bladder injury, or need for conversion to abdominal route. Commonest indication for surgery was fibroid uterus. Average duration of surgery was 1.2 hours. Average blood loss was 49 ml. Post-operative complications were minimal. Average hospital stay was 4.3 days. Patient mobility and ambulation was early, with minimal need for pain relief.
Conclusions: The study concludes that patients requiring hysterectomy for benign uterine pathologies without prolapse can be given an option of non-descent vaginal hysterectomy, because of the advantages that it has, over the abdominal route.

Published: November 2024

Background: Oligohydramnios is one of the major causes of perinatal  morbidity and mortality. The sonographic diagnosis of oligohydramnios is usually based on an AFI≤5 cm or on a single deepest pocket of amniotic fluid≤2 cm. Our study was aimed to study the perinatal outcome in oligohydramnios. Aim and objective were to study obstetric risk  factors  associated with oligohydramnios and maternal outcome in the form of  mode of delivery, and to assess neonatal complications in terms of APGAR score at birth, NICU  admission rates, meconium stained liquor and still birth rates.
Methods: Present study  is a prospective   study   on   outcome   of pregnancy in oligohydroamnios. Study was conducted at department of obstetrics and gynaecology at SMT SCL general hospital, Ahmedabad from January 2024 to July 2024. A total of 60 women singleton pregnancy with oligohydroamnios (AFI <5) in third trimester admitted as either booked or referral cases, were included in the study.
Results: The present study is of 60 cases of oligohydramnios in this study caesarean section rate was higher in 20-25 years age group and operative morbidity is more common in primipara group. Most common cause of oligohydramnios is idiopathic followed by post-date. LSCS rate is significantly higher in non-reactive NST group. Most common indication to perform caesarean section was fetal distress.
Conclusions: AFI is an important and convenient screening  test for prediction of perinatal outcome. In presence of oligohydramnios, the risk of fetal distress, operative delivery, low Apgar score, low birth weight, perinatal morbidity and  mortality are more. Hence early detection  of oligohydramnios, associated  antenatal risk factors and  timely management can improve the maternal and fetal outcome.

Background: This study aimed to evaluate the impact of preoperative carbohydrate loading on insulin resistance and clinical outcomes in patients undergoing elective gynecological surgeries.
Methods: A single-center, parallel-group, randomized controlled study was conducted at the Post Graduate Institute of Medical Education and Research, Chandigarh, India. Thirty-nine patients were randomized into two groups: the carbohydrate loading group (CHO, n=20) received 600 ml of a carbohydrate-rich drink the day before surgery and 200 ml two hours before surgery; the control group (CO, n=19) fasted overnight.
Results: Baseline serum insulin, blood glucose, and insulin resistance levels were similar between the groups. Two hours before surgery, the CO group had significantly higher serum insulin levels (7.5±5.6 IU/ml) compared to the CHO group (4.5±2.9 IU/ml) (t=2.08, p=0.04). Insulin resistance was also higher in the CO group (1.9±1.6) compared to the CHO group (0.9±0.6) (t=2.40, p=0.02). Seventy-five percent of the CHO group regained bowel sounds within 24 hours post-surgery, compared to seventy-three percent of the CO group, who achieved bowel sounds after 24 hours (χ²=9.24, p=0.02). No significant differences were observed in postoperative mobilization, urinary catheter removal, fever, nausea, vomiting, length of hospital stay, or surgical site infections.
Conclusions: Preoperative carbohydrate loading reduces insulin resistance and facilitates faster bowel recovery without increasing postoperative complications in elective gynecological surgery.
The hidden crisis: unsafe abortion and the fight for women’s health
Authors: Afsana  , Alam Tehzeeb , Mateena Yetoo
Published: November 2024

Background: In addition to having theological, moral, cultural, and political implications, abortion is a sensitive and divisive topic that also raises public health issues. Between 4.7 percent and 13.2 percent of maternal deaths each year are caused by unsafe abortion. Every year, unsafe abortions result in the hospitalization of more than 7 million women in impoverished countries.
Methods: The structural violence repertoire was used as a theoretical lens, the women were assisted in in-depth interviews to reflect and narrate the perceptions around abortion, and the qualitative approach was adopted for developing the narratives through oral history.
Results: According to studies, women frequently engage in risky abortion procedures and employ the same inexperienced personnel and traditional techniques that pose health risks. The findings also showed that the rate of induced abortion is rising, and it remains a mystery as to why women choose to have their abortions outside of hospitals and expose themselves to a variety of hazards.
Conclusions: Therefore, it is important to understand the extent of structural violence related to unsafe abortions and to implement a program to raise knowledge of health services.
