Abortion is the removal of an embryo or fetus weighing less than 500 grams from its mother. It can either be spontaneous (unprompted) or induced. Abortion remains one of the leading causes of maternal deaths in developing countries with induced abortion being the key cause. In 2014 from January to August, 9 abortion related deaths occurred in Botswana. There are several reasons female students in tertiary institutions resort to seeking induced abortion which include the socio-demographics like age and socio-economic factors like financial instability. Parental fears, unintended pregnancy and pressure from the partner also force females to terminate pregnancy. Induced abortion has claimed many women’s lives especially in developing countries with very restrictive abortion laws like Botswana as women do not access safe abortion care services. The study intends to establish the determinants of induced abortion among female students in selected tertiary learning institutions in Gaborone City, Botswana. It concentrated primarily on determining the prevalence of induced abortion. This was a descriptive cross-sectional study using both quantitative and qualitative data collection techniques. Systematic random sampling technique was used to come up with 278 participants. Prior to commencement of data collection, all ethical and logistical prerequisites were satisfied. Informed consent was solicited from all the study participants and the purpose of the study was fully explained. A self-administered questionnaire was used to collect data. Microsoft Excel spread sheet was used to code, clean, and enter the data, which was then exported for analysis to the statistical package for social sciences version 24. Frequency distribution tables, percentages graphs, and pie charts were used to illustrate the descriptive information. The study revealed that prevalence of induced abortion among female students in Gaborone City is 7.9%. They even suggested that induced abortion be liberalized. Age was the only socio-demographic factor associated with induced abortion with p = 0.047 using Chi Square test χ<sup>2</sup> = 7.609, df = 3. The study findings concluded that female students resort to induced abortion as a result of pressure from both parents and male partners especially when the pregnancy is unintended. The study recommends that the abortion law in Botswana be made liberal to ease access to safe abortion care services. It also recommends that contraceptive commodities should consistently be available in public health facilities. 展开更多

Background: Infertility and abortion are significant reproductive health concerns globally, impacting individuals' well-being and healthcare systems. In Saudi Arabia, cultural, social, and religious factors influence perceptions and management of these issues, necessitating research to understand the patterns and associated factors. Study Aim: This cross-sectional study aimed to investigate the patterns of infertility and abortion among 458 women in Saudi Arabia, focusing on demographic profiles, reproductive histories, medical conditions, and lifestyle factors. Methodology: Participants were recruited from healthcare facilities, and data on age, BMI, reproductive history, medical conditions, assisted reproduction methods, and lifestyle behaviors were collected. Statistical analyses, including chi-square tests, were conducted to examine associations between variables. Results: The majority of participants were aged 30 - 39 years (47.4%), with 76.9% experiencing secondary infertility. Among those with offspring (76.9%), 31% reported using assisted reproduction methods, primarily ovarian stimulators (54.2%). Abortion history was reported by 39.5% of participants. Significant associations were found between age and infertility type (X2 = 5.8, p = 0.054), having offspring and infertility type (X2 = 458.0, p = 0.001), menstrual irregularity and infertility type (X2 = 11.4, p = 0.001), and abortion history and delayed fertility (X2 = 10.4, p = 0.001). Conclusion: Our study reveals significant associations between demographic, medical, and lifestyle factors with infertility patterns and abortion history among Saudi women. These findings emphasize the need for tailored interventions addressing medical conditions, age-related factors, and access to reproductive healthcare services. 展开更多

Background: The absence of a safe and effective therapy for recurrent spontaneous abortion due to a maternofetal failure in immunological tolerance remains an intractable clinical obstacle for surgeons. Recently, traditional Chinese medicine has become a feasible alternative for certain diseases, including recurrent spontaneous abortion. However, because of the complex composition of the traditional Chinese medicine formula, its action mechanism remains unclear. Methods: We selected two isolated active ingredients (RAMP and baicalin) from the traditional Chinese medicine formula and used an abortion-prone CBA/J × DBA/2 model to simulate human RSA and compared the changes in fetal resorption rate, Treg cell percentage, and relevant cytokines before and after combination therapy. In addition, The mechanisms were preliminarily discussed using in vitro differentiation models. Results: In CBA/J × DBA/2 abortion-prone mice, the combination therapy resulted in a lower embryo resorption rate compared to that obtained with individual delivery of either RAMP or baicalin, thereby playing an embryo-protective role through the increase in Treg cells for the maintenance of maternal-fetal immune tolerance. In in vitro primary cell differentiation experiments, the concentration of Treg cells significantly increased from 11% to 17.9% after the combination therapy compared to that of the single administration group. Conclusion: the synergistic effects of RAMP and baicalin were responsible for Treg differentiation. The present study provides a solid basis for improving the applicability of traditional Chinese herbs in the treatment of recurrent spontaneous abortion. 展开更多

Genetic factors are thought to play an important role in the etiology of RSA. With recent advances in genetic testing technologies, there has been an increasing interest in using these tools to diagnose the etiology of RSA. This review discusses the different types of genetic testing methods, such as karyotyping, chromosomal microarray analysis, next-generation sequencing, and their applications in the diagnosis of the etiology RSA. The use of genetic testing in the diagnosis of RSA has the potential to improve the accuracy of diagnosis and the understanding of the underlying mechanisms of the disorder, which could lead to better management and treatment of affected individuals. 展开更多

Background: Unsafe abortions are one of the leading causes of maternal mortality, especially in developing countries. In Cameroon, the maternal mortality rate remains high, and the scarcity of data on abortions leads to a lack of solid evidence to advocate on the extent of the abortions related complications. Our objective was to evaluate the unsafe abortions related complications, and to assess the difficulties of accessing safe abortions in our setting. Methods: We carried out a meta-analytic and systematic review in the biomedical databases MEDLINE (Pubmed), Google Scholar and African Journal Online concerning unsafe abortions and/or difficulties in accessing safe abortions in Cameroon. The keywords used for the search are seen in table I. Selection of studies was simultaneously done by two authors. Data were extracted through a form designed on Google Form. We used a random-effect model for proportion estimation, and The I<sup>2</sup> and Q statistics to assess the extent of heterogeneity. Results: A total of 430 studies were identified, from which 28 were included and analysed. About 5% (95% CI: 3 - 7) of unsafe abortions leads to death. The contribution of unsafe abortions in maternal deaths was 23% (95% CI: 20 - 27). The rate of severe bleeding and/or anemia were 40% (95% CI: 18 - 63) and the rate of infection was 17% (95% CI: 7 - 28), dominated by pelvic infections, pelviperitonitis, severe sepsis, and septic shock. Case reports described uterine perforations, uterine rupture during the following pregnancy. Abortion was performed in the practitioner’s or patient’s home in 41.4% of cases, in a health center in 35.1% of cases, in a private clinic in 21.2% of cases, drugs selling places and in traditional healer clinics. The restriction of abortion laws, the stigma surrounding abortion and its consequences at any level of the society, lead to the underreporting of unsafe abortions and a deep reluctance to advocate for safe abortion services. Conclusion: The strengthening of awareness campaigns for provider behavior change communication, family planning, the de-stigmatization of abortions, the training of health personnel in post-abortion care, a multidisciplinary and multicentric action would contribute to the reduction in morbidity and mortality due to abortions. 展开更多

Background: Retention of fetal bones is a rare cause of abnormal uterine bleeding. Others may present as subfertility, chronic pelvic pain, abnormal vaginal discharge, menometrorrhagia, dysmenorrhea and spontaneous expulsion of bony fragments. Incidence is 0.26% among patients undergoing hysteroscopy. Aim: To document a pattern of presentation of retained fetal bone and its management. Case Presentation: Our patient is an 18-year old who presented with vaginal bleeding of four weeks duration and managed for abnormal uterine bleeding due to retained fetal bone following second trimester abortion. Conclusion: The use of transvaginal ultrasound in making diagnosis of retained fetal bone is effective. Treatment by removal of bones through evacuation by dilatation and curettage or hysteroscopy brings about resolution of symptoms. Use of pelvic ultrasonography to confirm complete evacuation of the uterus after abortion especially second trimester abortion could aid in early diagnosis and management of incomplete abortion. 展开更多

Introduction: In developed countries in general and particularly in the Central African Republic, clandestine abortions constitute a real health problem. The aim of our work was to study the method of carrying out clandestine abortions, to describe the profile of the providers and the complications that result from it. Patients and Methods: This was a descriptive cross-sectional study of patients hospitalized at the University Hospital Center for Sino-Central African Friendship (CHUASC) from 2015 to 2019 on 236 cases. Results: We identified a total of 254 patients for 8039 live births in the same period, a frequency of 3.16%. The age of the patients was between 15 years old and 48 years old with an average of 25 years old. Singles accounted for 42.5%. Induced abortions were more performed among students (32.6%) and the unemployed 53.6%. Contraception was used in 11.5% of cases. The methods used were numerous: misoprostol (32%), the traditional method (18%), the mechanical method (50%). In this method, we note the dilation of the cervix by the cassava stem;Hegar’s candles;the probes, which are infusion tubes cut and introduced into the cervix, of which 2 cases had escaped at the level of the uterine muscles and emerged under the skin at the pubis part two years later. The practice of induced abortions in our series was done by medical students in 37.3% followed by unqualified staff in 49.7%. It took place either at home or in centers managed by Non-Governmental Organizations. The aseptic conditions were not perfect. Some patients (43.2%) were aware of the ensuing complications. All complications were present: hemorrhage (60.7%), pelviperitonitis (23.6%), uterine perforation (6.6%), peritonitis (2.8%) and death (2%) related to sepsis. Conclusion: Clandestine abortion remains a real health problem for young Central African women. 展开更多

Two rice maintaining lines with different drought tolerances, viz., Jin 23B (tolerant) and Zhenshan 97B (sensitive), were used to study the oxidative stress and soluble sugar in rice anthers and pollen viability under drought stress during flowering stage. Higher antioxidant enzyme activities and lower malonaldehyde (MDA) content in rice anthers were observed in Jin 23B than in Zhenshan 97B under drought stress. Further, a great increase in the content of soluble sugar in rice anthers of Jin 23B was observed across the whole drought exposure, while Zhenshan 97B showed significant decrease in soluble sugar during 9-12 d after drought stress (DADS). Accordingly, a marked decline of pollen fertility and activity, pollen numbers in an anther and pollen numbers on a stigma was observed in Zhenshan 97B, whereas little difference was found in Jin 23B. Thus, we suggest that pollen abortion caused by drought stress may be related with the reciprocity between oxidative stress and soluble sugar content in rice anthers. 展开更多

The terminal flower buds of 6-yr-old Hanfu apple were used to study the ovule development, ovular characteristics, cell death of abortive ovules, and dynamic change of starch grain quantity in the embryo sac with paraffin slices and terminal deoxynucleotidyl transferase-mediated fluorescein deoxyuridine triphosphate nick-end labeling (TUNEL) system. Four anatropous ovules in each ventricle could be observed before flowering. With the developing of floral organ, the bulk of normal ovules enlarged in each ventricle, the mature embryo sac differentiated into nucellus, and the egg cell developed into zygote by double fertilization. A large number of starch grains were observed during pollen tube growth and double fertilization, which guaranteed basic nutrient supply in the normal development of ovules. Moreover, abortion phenomenon of runtish ovules emerged at the stages of mature embryo sac, double fertilization and zygote development. The abortion characteristics included deformity of ovule development, degradation of nucellus tissue, separation between funiculus and ovule, abnormality of four-nucleate embryo sac, as well as development interruption of mature embryo sac. TUNEL analysis proved that ovule abortion was programmed cell death. 展开更多

To investigate the relationship between inducible nitric oxide synthase (iNOS) and the early spontaneous abortion. , in situ hybridization and immunohistochemistry were used to detect the expression of iNOS in trophoblasts in the early pregnancy with and without spontaneous abortion (group Ⅰ and group Ⅱ). By light microscopy and computer color magic image analysis system (CMIAS), light density (D) and the positive cell number per statistic square (N/S) in situ hybridiza- tion were used to analyze the positive cell index, while total positive cells (N) and the positive unit (Pu) were used in immunohistochemistry. By in situ hybridization, D and N/S in trophoblasts were 0.35±0. 028, 0. 07±0. 011 respectively in group Ⅰ and 0. 18±0.016,0. 015±0. 003 in group Ⅱ . In terms of immunohistochemical staining, N and Pu were 0. 058±0.007, 11. 94±2. 01 in group Ⅰand 0.013±0.009, 1.08±0. 35 in group Ⅱ in trophoblasts. Significant differences existed between two groups. It is concluded that the higher nitric oxide produced by the higher expression of iNOS in tro- phoblasts might play an important role in the early spontaneous abortion. 展开更多

The relationship between T cell immunoglobulin domain and mucin domain protein 3(Tim-3)/Galectin(Gal)-9 pathway and recurrent spontaneous abortion(RSA) was studied. Thirty-one pregnant women with RSA and 27 normal early gravidas were investigated to detect the levels of Tim-3 and Gal-9 in villi and deciduas by Western blotting. Meanwhile, the concentration of interleukin(IL)-4 and IL-12 in peripheral blood plasma was determined by ELISA in 25 healthy fertile non-pregnant controls, the normal early gravidas and pregnant women with RSA mentioned above, respectively. It was found that the relative expression levels of Tim-3 and Gal-9 in villi and deciduas were significantly increased in pregnant women with RSA as compared with those in the normal early gravidas. The concentration of IL-4 in peripheral blood plasma of pregnant women with RSA was lower than that of the normal early gravidas(P〈0.05) and healthy fertile non-pregnant controls(P〈0.05), but that of IL-2 in pregnant women with RSA was significantly higher than that of the normal early gravidas(P〈0.05) and healthy fertile non-pregnant controls(P〈0.05). It was suggested that the overexpression of Tim-3/Gal-9 pathway may be related to the pathogenesis of RSA. 展开更多

Objectives To explore the relationship between CD80 expression on lymphocytes at the fetomaternal interface and the fertility characteristics in CBA/J×DBA/2 mice as a model of recurrent spontaneous abortion (RSA) and to investigate the effects of lymphocyte immunotherapy (LIT) on the level of CD80 expression. Materials & Methods The characteristics of fertility in CBA/J×DBA/2 mice were observed in a 120 day period and compared with four normal fertile groups. In another 15 pairs of CBA/J×DBA/2 breedings, resorption rate on day 13 of pregnancy were calculated and the proportion of CD80 + cells at the fetomaternal interface were determined by using two color flow cytometric analysis, mainly stained with CD80 FITC and CD45 PE. In order to determine the identity of CD80 + cells, the expression levels of CD3(T cell marker), DX5(NK cell marker), and MHC II(antigen presenting cell marker) were detected in this cell population. Furthermore, the resorption rate and the proportion of CD80 + cells among CBA/J×DBA/2 breedings with and without immunotherapy were also determined and compared with normal fertile controls. Results The characteristics of abortion in CBA/J×DBA/2 mice were recurrent abortion on about day 10 of gestation. The resorption rate in CBA/J×DBA/2 mice was significantly higher than that in BALB/c×DBA/2 mice (30.8%±16.6% vs. 7.7%±6.7%, P<0.01). Accordingly, the proportion of CD80 + cells evaluated at the fetomaternal interface in CBA/J×DBA/2 mice was also significantly higher (11.7% ±5.8% vs. 3.9%±1.8%, P<0.01). Resorption rate of CBA/J×DBA/2 mice underwent of LIT was significantly lower than that without LIT, and this decreased rate was correlated with decreased proportion of CD80 + cells. Conclusion In CBA/J×DBA/2 mice model, the characteristics of abortion seem to be peri implantation embryo resorption. A correlation between early embryonic waste and higher CD80 proportion at the fetomaternal interface suggests that CD80 + cells may be an important determinant in recurrent peri implantation abortion. 展开更多

Aim: To evaluate the benefits and hazards of routine progesterone supplementation in threatened abortion and whether it is a sound practice or not. Materials and Methods: This study was conducted at Obstetrics and Gynecology Department, Tanta University in the period from January 2018 to December 2018. Eligible patients (n = 190) were randomly allocated into 2 groups: study group who will receive progesterone supplementation (prog. group) and control group who will receive no treatment (place. group). Results: No significant differences were found between both groups regarding all demographic data and pregnancy characteristics. Abortions were higher in place. group 17 (23.94%) than in prog. group 12 (16.44%) with no significant difference p value = 0.263. The incidence of preterm labour was also higher in the place. group 22 (30.99%) in comparison to the prog. group 17 (23.29%) with no significant difference p value = 0.300. Conclusion: Progesterone supplementation in threatened abortion was not beneficial although it reduced abortion and preterm labour rates. 展开更多

This early vaginal bleeding happens in about 25% of pregnant women. The medications including progesterone, uterine muscle relaxant or human chorionic gonadotropin have essential effects in developing pregnancy, but the clinical data are insufficient to prescribe them. In recent decades, medicinal herbs can help us to present new treatments. Grape (Vitis vinifera L.) can protect the fetus from the perspective of Persian medicine. So, we hypothesize about the salutary effects of grape in miscarriage prevention. We found five standard expected mechanisms of grape to prevent threatened abortion: immunomodulatory and anti-inflammatory, anti-oxidant, anti-contraction, hormonal and anti-stress activities. Grape reduces nitric oxide, prostaglandin E2, expression of nuclear factor κB and other pro-inflammatory cytokines like IL (Interleukin)-1β, IL-6, IL-8, and tumor necrosis factor-α. It also elevates anti-inflammatory mediators and expression of peroxisome proliferator-activated receptor-γ. Grape polyphenols have a crucial role in fetus protection with high antioxidant power and other functions such as prevention of stress-triggered abortion with proanthocyanidins, or hormonal effects and inhibition of uterine contractions with resveratrol. So according to these studies, grape probably has effects on the immune and endocrine factors involved in threatened miscarriage. 展开更多

BACKGROUND Mifepristone-induced abortion(MIA)has been used worldwide to terminate pregnancies.However,the association between placenta accrete(PA)and MIA has seldom been reported.CASE SUMMARY A 26-year-old pregnant woman presented with painless vaginal bleeding at 35 wk of gestation.She had a medical abortion(mifepristone followed by misoprostol)1 year ago at the sixth week of gestation.Her personal history for previous surgery was negative.Abdominal ultrasonography showed a normal foetus with complete placenta previa.The foetal membrane ruptured with massive vaginal bleeding and severe abdominal pain.An emergency Caesarean section was performed,and the newborn was delivered.The placenta failed to expel and manual extraction was carried out.A large defect was noted in the uterine fundus and repair of the uterine rupture was conducted immediately.The postoperative pathology report showed placenta accreta.CONCLUSION The evidence suggests a possible etiologic role of MIA in PA,as the incidence of PA after MIA is much higher than general population.Millions of pregnancies are complicated by PA each year,some of which result in fatality.To prevent subsequent placental complications after MIA,hormonal supplementation might be a promising therapeutic options.However,further studies are needed to identify the high-risk factors and to confirm the effectiveness of estrogen supplement therapy. 展开更多
