Abstract:

Blighted ovum adalah suatu keadaan hasil konsepsi yang tidak mengandung janin. Diperkirakan di seluruh dunia. Blighted ovum merupakan 60% dari penyebab kasus keguguran, di Indonesia ditemukan 37% dari setiap 100 kehamilan. Penelitian inibersifat analitik dengan pendekatan case control. Sampel adalah seluruh ibu hamil, sampel 36 orang ibu-ibu hamil yang mengalami blighted ovum dan 36 orang ibu-ibu hamil normal yaitu sebanyak 72 orang. Teknik pengambilan sampel menggunakan purposive sampling Pengumpulan data dilakukan dengan menggunakan cheklist. Dari 72 responden terdapat 12 orang ibu hamil dari kelompok usia yang beresiko terjadinya blighted ovum, sedangkan 60 orang lagi tidak beresiko terjadinya blighted ovum, nilai odds ratio 3.667, dan pada kelompok paritas terdapat 20 orang ibu hamil yang beresiko tinggi terjadinya blighted ovum dan 52 orang lagi tidak beresiko tinggi terjadinya bligted ovum, nilai Odds ratio 3.504.

Abstract:

Background: Blighted ovum is a pregnancy without a fetus (anembryonic pregnancy), so there is only a gestational sac and amniotic fluid. According to the World Health Organization (WHO) in 2016, it is estimated that 10-15% of clinical conceptions will experience abortion and 3% of them will experience blighted ovum. It is estimated that throughout the world, blighted ovum is the cause of 60% of miscarriages, even in ASEAN it reaches 51%, while in Indonesia it is found in 37% of every 100 pregnancies. Purpose: To determine the relationship between lifestyle and nutrition with the incidence of blighted ovum in pregnant women in the 1st trimester. Method: Quantitative research using a cross sectional approach. The population in this study were all mothers who experienced blighted ovum at Hastien Rengasdengklok Karawang Hospital on 12 June-28 August 2023, totaling 51 people with a sampling technique using total sampling. Results: There is no relationship between the respondent's lifestyle and nutrition or eating patterns and the incidence of blighted ovum because the p-value statistical test results for both variables are more than a significant value (a = 0.05), namely -0.75 (<0.05). Conclusion: There is no relationship between lifestyle choices and nutrition and the incidence of blighted ovum in pregnant women. Keywords: Blighted Ovum; Lifestyle; Nutrition. Pendahuluan: Blighted ovum merupakan kehamilan tanpa janin (anembryonic pregnancy), jadi hanya ada kantong gestasi (kantong kehamilan) dan air ketuban saja. menurut World Health Organization (WHO) tahun 2016, diperkirakan 10-15% hasil konsepsi klinis akan mengalami abortus dan 3% diantaranya adalah blighted ovum. Diperkirakan di seluruh dunia bahwa blighted ovum menjadi 60% dari penyebab kasus keguguran, bahkan di ASEAN mencapai 51%, sedangkan di Indonesia ditemukan 37% dari setiap 100 kehamilan. Tujuan: Untuk mengetahui hubungan gaya hidup dan nutrisi dengan terjadinya blighted ovum pada ibu hamil trimester 1 Metode: Penelitian kuantitatif menggunakan pendekatan cross sectional. Populasi dalam penelitian ini adalah seluruh ibu yang mengalami blighted ovum di Rumah Sakit Hastien Rengasdengklok Karawang pada tanggal 12 Juni-28 Agustus 2023 yang berjumlah 51 orang dengan teknik pengambilan sampel menggunakan total sampling. Hasil: Tidak terdapat hubungan antara gaya hidup dan nutrisi atau pola makan responden dengan kejadian blighted ovum karena hasil uji statistik p-value kedua variabel lebih dari nilai signifikan (a =0.05) yaitu -0.75 (<0.05). Simpulan: Tidak ada hubungan antara pilihan gaya hidup dan gizi dengan kejadian blighted ovum pada ibu hamil. Kata Kunci : Blighted Ovum; Gaya Hidup; Nutrisi.

Abstract:

Blighted ovum atau kehamilan anembrionik merupakan keadaan dimana seorang wanita hamil namun tidak terdapat janin didalam kandungannya, dikarenakan ovum yang dibuahi tidak berkembang. Hingga saat ini penyebab kejadian blighted ovum belum dapat dideteksi karena gejala yang tidak spesifik. Umumnya kejadian blighted ovum terjadi pada trimester I dan memungkinkan untuk terulang kembali pada kehamilan selanjutnya. Tujuan penelitian ini untuk mengetahui gambaran kejadian blighted ovum. Metode penelitian yang digunakan adalah Literature Review yang didapatkan dari 3 database yaitu PubMed, ResearchGate dan Google Scholar dengan kriteria inklusi jurnal terakreditasi Sinta dan Scopus. Hasil penelitian dari 5 jurnal yang telah diidentifikasi melalui proses literature review didapatkan karakteristik ibu hamil berdasarkan usia, paritas, imunologis, dan kelainan genetik ada pada ibu hamil dengan blighted ovum. Ibu hamil yang mengalami blighted ovum memiliki karakteristik usia >40 tahun dengan paritas multigravida dan grandemultigravida serta kelainan genetik.

Abstract:

AbstractNormal men after stepping into the adolescent phase, they must produce sperm. Likewise, normal women after reaching the adolescent phase, they must produce ovum. However, there are still many men and women who have produced sperm or ovum and do not know about the hormones that affect on producing sperm or ovum. In males, the hypothalamus secretes releasing factors and stimulates the anterior pituitary gland to produce follicle stimulating hormone (FSH) and interstitial cell stimulating hormone (ICSH). The combination of FSH and ICSH will stimulate the testes to produce the hormone testosterone. The hormone testosterone is responsible for sperm production, penis growth, facial hair, and widening of the shoulders. In women, the hypothalamus secretes releasing factors and stimulates the anterior pituitary gland to produce follicle stimulating hormone (FSH) and luteinizing hormone (LH). FSH stimulates young follicles until they become mature follicles. Mature follicles due to the influence of luteinizing hormone will rupture, so that the ovum is released from the follicle. Follicles that no longer contain ovum will turn into a corpus luteum. The corpus luteum then produces the hormones progesterone and estrogen to keep the corpus luteum from being damaged.Keywords: Hormones, sperm formation, and ovum formation.

It is estimated that worldwide Blighted ovum is 60% of the causes of miscarriage cases, in ASEAN (association of Southeast Asian Nations) it reaches 51%, in Indonesia it is found 37% of every 100 pregnancies, in Yogyakarta Province it reaches 30% of 100 pregnancies and in Sleman Regency. as much as 43.39% (WHO, 2015). The incidence rate at PKU Muhammadiyah Gamping shows an increase in the Blighted ovum rate during the last 3 years in 2016 as much as 6.02%, in 2017 it increased by 6.05%, and in 2018 it increased by 6.06% (Kemenkes RI, 2018). Mothers who experience abortions due to blighted ovum have characteristics including age, parity, nutrition and gestational spacing, in addition, age, parity, nutrition and gestational spacing are also factors that cause blighted ovum. Objective: To identify the factors that influence the incidence of blighted ovum pregnancy. Research Methodology: This type of research is analytical observational with a cross-sectional approach. The location of this research is PKU Muhammadiyah Gamping Yogyakarta with a sample of 30 respondents and the sampling technique is Simple Random Sampling.

Abstract:

Polyspermy is a major puzzle in reproductive biology. In some taxa, multiple sperm enter the ovum as part of the normal fertilization process, whereas in others, penetration of the ovum by more than one sperm is lethal. In birds, several sperm typically enter the germinal disc, yet only one fuses with the female pronucleus. It is unclear whether supernumerary sperm play an essential role in the avian fertilization process and, if they do, how females regulate the progression of sperm through the oviduct to ensure an appropriate number reach the ovum. Here, we show that when very few sperm penetrate the avian ovum, embryos are unlikely to survive beyond the earliest stages of development. We also show that when the number of inseminated sperm is limited, a greater proportion than expected reach and penetrate the ovum, indicating that females compensate for low sperm numbers in the oviduct. Our results suggest a functional role for supernumerary sperm in the processes of fertilization and early embryogenesis, providing an exciting expansion of our understanding of sperm function in birds.

Abstract:

Ovum Pick-up (OPU) associated with IVF has become advancement in ruminant reproduction. Transvaginal OPU guided by ultrasound is a non- invasive technique for cumulating oocytes from Graafian and antral follicles from live donor animals especially from cattle. Laparoscopic OPU in combination with in vitro embryo production increases the possibility of obtaining viable offspring in small ruminants. OPU does not impede with the usual reproduction and production performance of the donor animals and can be apply in various physiological states and circumstances of animals like different ages and reproductive disorders. The persistent collection of oocytes through OPU techniques concedes us to acquire the highest possible progeny of animals with merit genetic value, genetic improvement and advancement in animal selection. Here, we are presenting an overview of OPU from ruminants with factors affecting their outcome.

Abstract:

Background: This study was performed to determine the level of serum C-reactive protein (CRP) in day of ovum pickup and embryo transfer as a predictor for success in patients undergoing In-Vitro Fertilization (IVF) and Intracytoplasmic Sperm injection (ICSI).Methods: This study was a cross sectional study (prospective) that was conducted in assisted reproduction unit in Al-Azhar University Hospital on 50 infertile patients who were candidate for IVF/ICSI, using standard long protocol, blood was drawn two times during cycle, in the day of ovum pick up and the day of embryo transfer.Results: In (70.6 %) the serum of CRP level was higher in day of embryo transfer than day of ovum pick up. The ratio of CRP level in the day of embryo transfer to the day of ovum pick up was heigher (1.54) in patients who became pregnant after ICSI, patients with less than this ratio have not been pregnant.Conclusions: Controlled ovarian hyper stimulation and puncture of ovaries can potentiate systemic stimulation so increasing serum CRP level in day of embryo transfer rather than day of ovum pick up can predict success in patients undergoing IVF/ICSI.

Abstract:

Klasifikasi Faktor Blighted Ovum atau janin tidak berkembang dilakukan mengingat kasus Blighted Ovum banyak terjadi pada ibu hamil. Blighted Ovum merupakan 60% dari penyebab keguguran, di Indonesia ditemukan 37% dari setiap 100 kehamilan. Klasifikasi menggunakan Naïve Bayes berbasis Particle Swarm Optimization (PSO) yang hanya membutuhkan data training yang kecil untuk menentukan estimasi parameter yang diperlukan dalam proses pengklasifikasian dan penggunaan Particle Swarm Optimization dapat meningkatkan nilai akurasi serta memecahkan masalah optimasi. Dengan proses pemilihan data variable dan data attribute untuk membuat kuisioner sebagai metode pengambilan data. Hasil klasifikasi blighted ovum pada wanita hamil menggunakan algoritma Naïve Bayes dengan framework Rapid Miner mendapatkan nilai akurasi sebesar 71,56% dengan Area Under Curve (AUC) 0,674 termasuk dalam kategori klasifikasi yang baik. Setelah menggunakan optimasi PSO nilai akurasi naik menjadi 79,82% dengan Area Under Curve 0,764 termasuk kategori klasifikasi yang baik. Naïve bayes merupakan metode yang cocok untuk klasifikasi, dan PSO bisa membuat nilai akurasi dan AUC lebih baik lagi.

Abstract:

In vitro embryo production (IVP) is an important tool to enhance genetic gain in cattle. However, oocyte quality is a limiting factor for the success of IVP programs in high-producing donors. A series of studies using protocols for follicular wave synchronization and superstimulation before ovum pickup were performed to improve the efficiency of ovum pickup and in vitro production in dairy cattle. The first study evaluated superstimulation with FSH (Folltropin-V®) before ovum pickup in lactating (n = 15) and non-lactating (n = 15) Holstein donors in a crossover design. Cows underwent synchronization of follicle wave emergence (FWE) and at the expected time of FWE, the FSH group received a total dosage of 200 mg of FSH in 4 decreasing doses 12 h apart; controls received no FSH, and ovum pickup was conducted 72 h after the expected FWE in all cows. The FSH-treated cows had a higher (P < 0.01) percentage of medium-sized follicles (6 to 10 mm) at the time of ovum pickup (55.1%) than control cows (20.8%) as well as lower cumulus‐oocyte complexes (COC) recovery rates (60.0 v. 69.8%, respectively; P = 0.002). However, FSH-treated cows had a higher blastocyst production rate (34.5 v. 19.8%; P < 0.01) and more transferable embryos per ovum pickup session (3.0 ± 0.5 v. 1.8 ± 0.4; P = 0.02). Subsequent trials evaluated plasma FSH profiles in 23 heifers and in vitro production following ovum pickup in 90 non-lactating Holstein donors superstimulated with a single IM injection of FSH in 0.5% hyaluronan (HA; MAP-5®, 50 mg). Controls received no treatment, while the F200 group received 200 mg of FSH in 4 decreasing doses 12 h apart. The F200HA and F300HA groups received 200 or 300 mg of FSH in 5 or 7.5 mL, respectively, of 0.5% HA by a single IM injection. Circulating FSH area under curve (AUC) in FSH-treated animals was greater than in the control group (P = 0.02). Although the AUC for F200 group did not differ from HA groups (P = 0.56), the total period of time plasma FSH levels were elevated was greater than in the HA groups (P < 0.01). In the IVP trial, FSH-treated cows had a greater proportion of medium-sized (6–10 mm) follicles than controls (P < 0.001). Also, numbers of follicles (P = 0.01) retrieved (control: 13.1 ± 1.0; F200: 16.5 ± 1.2; F200HA: 19.5 ± 2.1; F300HA: 15.4 ± 1.4; P = 0.01) and blastocysts produced per ovum pickup session (control: 2.4 ± 0.5; F200: 3.7 ± 0.7; F200HA: 4.7 ± 0.7; F300HA: 3.1 ± 0.6; P = 0.06) were greater in cows receiving FSH, regardless of treatment. Cows in the F200HA group had a greater recovery rate (P = 0.009), number of COC cultured (P = 0.04), and blastocysts per ovum pickup session (P = 0.06) than cows in the F300HA group. In conclusion, superstimulation of Holstein donors before ovum pickup increased the efficiency of in vitro production. Additionally, a single IM dose of FSH in 0.5% HA resulted in similar plasma FSH profiles to twice-daily FSH treatment. Non-lactating donors treated with FSH produced more embryos per ovum pickup session regardless of FSH treatment. Lastly, all in vitro-produced endpoints were greater following a single dose of 200 mg of FSH in 0.5% HA than 300 mg of FSH in 0.5% HA.

Abstract:

Chinese forest frog ovum oil is a medicinal food high in cholesterol. In the current study, we evaluated the relative efficiency of β-cyclodextrin, crosslinked β-cyclodextrin, and silica gel adsorption on cholesterol removal from Rana chensinensis ovum oil. Beta-cyclodextrin had the highest cholesterol reduction rate (60.84 ± 4.45%) among the three methods. We further evaluated the efficiency of cholesterol removal by beta-cyclodextrin in the presence of ethanol and higher (55°C) temperature. This resulted into cholesterol removal rate of as high as 76%. Interestingly, monounsaturated fatty acids increased from 4.96% to 29.12% after cholesterol removal. We conclude that beta-cyclodextrin is an excellent adsorbent for removing cholesterol from ovum oil.

Abstract:

Among internal fertilizers, typically fewer than 1% sperm survive the journey through the oviduct. Several studies suggest that the sperm reaching the ovum—the ‘fertilizing set’—comprise a non-random sub-population, but the characteristics of this group remain unclear. We tested whether oviductal selection in birds results in a morphologically distinct subset of sperm, by exploiting the fact that the fertilizing set are trapped by the perivitelline layer of the ovum. We show that these sperm have remarkably low morphological variation, as well as smaller head size and greater tail length, compared with those inseminated. Our study shows that the morphological composition of sperm—rather than length alone—influences success in reaching the ovum.

Abstract:

Familial early-onset Alzheimer’s disease (AD) is more probable in individuals coming from mothers diagnosed with AD than from fathers diagnosed with AD. Studies in animal models have shown maternal imprinting due to the transmission to the embryo of altered material in the ovum. In the case of transgenic animals harboring a mutated form of the human amyloid precursor protein (APP), offspring from crosses with wild-type (WT) fathers and transgenic mothers display more abnormalities than offspring from crosses with transgenic fathers and WT mothers. Expression of the mutated APP in the ovum may lead to alterations that may be genetic and/or epigenetic in the nuclear and/or the mitochondrial DNA. These modifications that are transmitted to the new living beings affect more mitochondrial proteins and, therefore, the mitochondrial function may be affected in adulthood by trends present in the ovum.
