Authors: Miglani Urvashi , Kohli Jasmine K. , Laul Poonam , Grover Monika S. , Madan Richa
Published: March 2024

Background: Approximately 529,000 women die from pregnancy-related causes annually and almost 99% of these occur in developing nations. Even with decline, India still is one of the major contributors to maternal deaths in the world. Hence, the present study was conducted to assess the causes, sociodemographic factors and level of delay influencing maternal mortality.
Methods: A retrospective descriptive study based on all maternal deaths within 2.5 years from June 2020 to December 2022 in tertiary care center New Delhi was included. All deaths were assessed for sociodemographic risk factor and processed using descriptive statistics for various variables.
Results: During the study 77 deaths were identified. 48 deaths were direct and 29 were indirect maternal deaths. Sepsis and infectious diseases were the leading cause of direct and indirect maternal death respectively. 47% women died at more than 34 weeks’ gestation.12 women died undelivered. 65 women who died in the postpartum period, caesarean section was performed in 32%. Of total deaths 53 women were unbooked and level 1 delay in 78% cases.
Conclusions: Education and awareness of importance of antenatal care, diagnosis and management of anemia to be given prime importance. Institutional deliveries to be encouraged. Optimization of comorbid conditions in the preoperative period is quintessential.
Study of fetomaternal implications in intrauterine growth restriction pregnancies
Authors: Sharma Prachi , Mehta Amiya U.
Published: March 2024

Background: Fetal growth restriction (FGR) is a pathological condition in which a fetus has not achieved its genetic growth potential. FGR incidence is 6 times higher in underdeveloped and developing countries as compared to the developed world.
Methods: This is a retrospective study done in the department of obstetrics and gynaecology, civil hospital and B. J. Medical college, Ahmedabad over the period of 6 months from December 2022 to May 2023. A total of 30 cases of intrauterine growth restriction (IUGR) pregnancies were studied.
Results: Majority of the study population, 60% belonged to younger age group of 20-30 years. Multiparity was associated with IUGR babies. Majority of patients i.e. 76.66%. Presented at gestational age of ≥37 weeks and 23.33% at <37 weeks. Most IUGR babies (73.33%) had a birth weight between 2 to 2.5 kg. One third of babies required NICU admission while the perinatal mortality was 10%. Doppler changes in umbilical artery were noted in 27% of cases of IUGR. Among risk factors anemia, preeclampsia and oligohydramnios had equal contributions at 10% each. Previous history for SGA baby is a significant association in 16% of cases. Induction of labor was done in 60% cases, 63% were delivered vaginally and rest via lower segment caesarean section (LSCS), the most common indication of LSCS was fetal distress.
Conclusions: The study concluded that IUGR continues to be one of the major etiological factors for fetal morbidity and mortality and increase in rates of LSCS contributing maternal morbidity. IUGR was commonly observed in multigravida patients lacking antenatal care. Anemia and hypertensive disorders of pregnancy as well as oligohydramnios are the potential risk factors for IUGR.

Granulosa tumors are rare ovarian tumors they belong to sex-cord and stromal tumor family. They are the most common type of malignant stromal tumor and have a good prognosis. There are two types: the adult type (AGCTs), which occurs most frequently between the ages of 40 and 70, and the juvenile type (JGCTs), which is uncommon. Juvenile granulosa tumors tend to involve a single ovary and occur mainly in people who are younger than 30 years. Metastatic spread is rare and, if present, is usually limited to the peritoneal cavity. We report a case of ovarian juvenile granulosa cell tumor extending to the jejunum and peritoneum in an 18-year-old female patient received in our institution.

Published: March 2024

The cervical fibroids are rare and large cervical fibroids are rarer. Removing large cervical fibroids when a patient desires future fertility is a surgical challenge because of the risks of significant blood loss, bladder and ureteric injury, and unplanned hysterectomy. For women who desire future fertility, myomectomy can improve the chances of pregnancy by restoring normal anatomy. In this article, we describe a successful pregnancy following the restoration of the normal anatomy of the cervix by a challenging myomectomy in a sub-fertile patient with a large cervical fibroid. A 38-year-old nulliparous lady presented to the reproductive endocrinology and infertility (REI) department of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh with primary sub-fertility for five and half years, and dysmenorrhea for 2 years. She was a regularly menstruating woman with average flow and duration. Being a resident of Canada, she was diagnosed there as a case of large cervical fibroid (10×9 cm) by TVS extending up to the posterior wall of the uterus, cervix, and upper vagina impacted in the pouch of Douglas during infertility workup. For this reason, she was advised for in vitro fertilization (IVF) keeping the fibroid in situ. However, due to the failure of embryo transfer with this large cervical fibroid, she was advised for embryo transfer following myomectomy. Hysteroscopic myomectomy was tried first (in February 2019 in Canada) but was unable to be removed. Then Laparotomy was tried (in September 2019 in Canada) but failed again. Being a complicated case, she was counselled there for myomectomy by a multidisciplinary approach with the high risk of injury to the urinary bladder, ureter, bowel, and other pelvic structures. But she refused to do a myomectomy there after knowing the dreadful complications with the fear of injury to the pelvic organs. With this problem, she went to different institutions both in the country and abroad but couldn’t get the proper treatment. Finally, she visited the outpatient department (OPD) of the REI department, BSMMU, Dhaka, Bangladesh with the hope of getting the most appropriate treatment for her and she was reassured, counselled, and managed by a challenging myomectomy (in March 2022) through a combined approach of the vagina and abdominal route without any significant intra and post-operative complications. Her whole post-operative period was uneventful, the anatomy of the cervix was restored and detected by TVS, and trial transfer was done before embryo transfer with easy negotiation to the cervix. Finally, she conceived 1 year after myomectomy with easy frozen embryo transfer. Myomectomy in expert hand even for the large cervical fibroid can restore normal anatomy and can achieve successful pregnancy outcomes.

Authors: Amelia Dessy Nur
Published: March 2024

This paper is aimed to analyse of Indonesian science teachers’ perspective regarding the implementation of online learning as an impact of the COVID-19 pandemic. In this study, three science teachers were asked their perspectives about the challenges and benefits of online teaching. The participants perceived obstacles in online learning are insufficient facilities, lack of parents’ engagement, challenges in adapting with new policies at school, impossibility to conduct the hands-on practicum, and a decrease in student enthusiasm to learn. The challenges are mainly caused due to the nature of online learning that requires new skills that are different from face-to-face classroom setting. However, online learning has caused the participants to grow their digital skills aside from having more flexibility in managing their time. This study suggests the importance to provide training for teachers to allow them to teach effectively in online setting.

Perkembangan science dan teknologi yang cepat menjadikan bioteknologi menjadi salah satu ilmu/pengetahuan yang harus dikuasai oleh warga negara Indonesia, karena disamping sangat berkaitan erat dengan kehidupan sehari-hari (daily life) juga sangat berhubungan dengan aspek ‘life skill’. Guna memberikan penekanan dan kebermaknaan tentang bioteknologi kepada siswa, guru dituntut untuk menciptakan pembelajaran yang benar dan dengan cara memberikan pemahaman yang benar pula pada siswanya. Bioteknologi merupakan salah satu topik yang dianggap sulit karena untuk memperoleh pemahaman yang benar dibutuhkan pengusaan konsep-konsep dasar yang seringkali bersifat abstrak. Lesson Study (LS) yaitu suatu model pembinaan profesi pendidik melalui pengkajian pembelajaran secara kolaboratif dan berkelanjutan berlandaskan prinsip-prinsip kolegalitas dan mutual learning untuk membangun ‘learning community’. Lesson Study dilaksanakan dalam tiga tahapan yaitu Plan (merencanakan), Do (melaksanakan), dan See (merefleksi) yang berkelanjutan. Tujuan dari penelitian ini adalah: mengobservasi dan memperoleh informasi tentang bagaimana usaha guru dan proses yang dilakukan guru dalam perencanaan, melaksanakan dan mengevaluasi secara sederhana pada konsep bioteknologi melalui metode eksperimen/praktikum di SMP. Observasi dilakukan terhadap seorang guru dan 33 siswa IX SMP I Pamulihan Kabupaten Sumedang. Pengumpulan data dalam penelitian menggunakan teknik: observasi terhadap aktivitas planing, pelaksanaan proses, dokumentasi bahan ajar (,renpel,silabus dan LKS) dan dokumentasi pelaksanaan pembelajaran,menjaring pendapat guru dan mengikuti kegiatan refleksi yang dilaksanakan setelah proses pembelajaran untuk mencatat tanggapan guru model, kepala sekolah dan para observer dalam implementasi. Hasil menunjukkan bahwa perencanaan, pelaksanaan dan evaluasi sebagai suatu kesatuan dalam strategi pembelajaran bioteknologi di SMP I Pamulihan dengan menggunakan metode praktikum/experiment cukup baik dilakukan oleh guru model. Kendala utama yang dihadapi guru dalam meliputi alokasi waktu, disamping kurangnya buku sumber dan kondisi siswa. Guru dan siswa merasa sangat suka dengan metode yang digunakan tetapi belum terlalu memberi dampak yang berarti pada peningkatan hasil belajar. Masih diperlukan upaya yang lebih keras untuk memperbaiki proses pembelajaran di kelas untuk menyiapkan calon guru dalam membelajarkan Bioteknologi

Artikel ini mengupas penelitian-penelitian yang dilakukan oleh RUMEC (Research in Undergraduate Mathematics Education Community) tentang penggunaan Teori APOS dalam pembelajaran Struktur Aljabar. Pembelajaran berdasarkan teori APOS dapat meningkatkan ketertarikan dan semangat mahasiswa pada matematika, yang merupakan hal yang potensial dimana hal ini akan memberikan keuntungan yang baik dalam segi akademik. Disamping itu mahasiswa cenderung memberikan perhatian yang khusus pada pembelajarannya.
Multisensual Representations of Isolation versus Intimacy Crisis in Polish Films about Youth: Love Tasting, All These Sleepless Nights and Sweat

Published: March 2024

The aim of the paper is to analyse three Polish films in terms of sensuous theory and the theory ‎of affects. We focused particularly on fragments of works portraying characters’ intense ‎emotional states. We were curious how the emotions and affects are presented in the plot and ‎form—and how the viewers can feel them. We have chosen three films by young Polish ‎directors about young people: Love Tasting (2020), All These Sleepless Nights (2016) and Sweat ‎‎(2020). All three works tell stories of failed relationships and rejection, but also portray young ‎people’s identity building. The films show their characters in vulnerable ‎positions, when they are prone to crisis. We wondered how the sensuous theory can combine the ‎analysed categories.‎
Early Exit Decisions in Finland: Investigating the Limbo between Unemployment and Retirement

Despite efforts to extend careers, workers continue to withdraw from working life before reaching the old-age pension age. The complexities behind early exit decisions have been extensively studied to understand the individual factors influencing the decision-making processes. However, fewer studies have attempted to understand how underlying cultural notions of age shape these decisions. Using qualitative longitudinal interview data from Finland, this article examined how individuals in the Finnish unemployment pathway to retirement position themselves between unemployment and retirement by drawing on age-specific discourses. Findings show that early exit was framed as the least problematic career option, although colored with ambiguity and anxiety. Individuals did not view themselves as retirees, and some expressed interest in continuing work. Nevertheless, age norms together with experienced, internalized, and expected ageism pushed individuals toward exit, highlighting the need to better understand and support individuals experiencing late-life unemployment.

This two-year field study aims to investigate the impact of organic pesticides used in organic Damask rose (Rosa damascena Mill.) fields on Arbuscular Mycorrhizal Fungal (AMF) colonization. Conducted in the renowned Rose Valley of Bulgaria, specifically in the village of Kliment, the experiment employed a randomized complete block design with two rows of 21 plants each in organic certified plots. The results revealed low AMF colonization in the first year, ranging between 14.78% and 20.89%, with no significant differences between treatments. In the second year, while no significant differences were observed between treatments (ranging from 48.00% to 76.49%), there was a notable increase in AMF colonization compared to the initial sampling. The study concluded that specific organic pesticides, including Neemazal, Limocide, Phytosev, and Nano sulfur, had minimal negative effects on AMF colonization. These findings contribute to understanding the implications of organic farming practices on AMF and soil health in the context of Damask rose cultivation.
