Abstract: 

Background: Abortion is an important and controversial issue and one of the important reasons for the mortality of pregnant women worldwide. This study aimed to predict the risk factors of abortion in pregnant women using artificial neural network, wavelet neural network, and adaptive neural fuzzy inference system. Materials and Methods: The study is an analytical-comparative modeling and data of 4437 pregnant women from the Ravansar Non-Communicable Disease (RaNCD) cohort study from 2014 to 2016 was used. First, six variables were chosen through the genetic algorithm approach, then artificial neural network (ANN), wavelet neural network (WNN), and adaptive neural fuzzy inference system (ANFIS) were run. Finally, the performance of the models was compared based on the evaluation criteria. All analyses were done in MATLAB R2019b software. Results: ANN with RMSE of 0. 019 showed better performance than ANFIS and WNN with 0. 42 and 1. 445, respectively. Further, the accuracy, sensitivity, and specificity in ANN were 100%, 99%, and 100%, while in WNN, they were 76. 2%, 76. 4%, and 66. 7%. However, when the researchers used three selected variables, the accuracy, sensitivity, and specificity as well as RMSE in ANFIS were 100%, 100% 100%, and 0,100%, 99%, 100%, and 0. 021 in ANN,and finally 76. 2%, 76. 4%, 38. 5%, and 1. 553 in WNN. Conclusion: The models with six input variables indicated that the artificial neural network has a better performance than the other two models, but based on the three variables, the fuzzy neural inference system performed better than the other two models.

Abstract: 

Background: Woman's decision-making for abortion entails understanding and assessing those options in the context of her unique situation, feelings, aspirations and beliefs. The objective of this study was to examine decision– making conflict and all relevant factors, among women seeking legal abortion authorization letter, referred to Legal Medical Centre in Tehran. Materials and Methods: In this cross-sectional study, decision-making conflict assessed using the decisional conflict scale (DCS) among 282 pregnant women in their first trimester. Descriptive and logistic regression analyses were undertaken to describe and explore collected data. Results: Eligible women requesting legal abortion were mostly in age group 25-34 years old (50. 4%. 142, M=31. 55, SD=6. 1, ranging from 17-46 years). They were mostly in gestational age<16 weeks, (212, 75. 2%), with average 14. 67 (SD=3. 51), range 15. 0 weeks (4-19 weeks). Some decision conflict (DCS score 25 or greater) was experienced by 182 (64. 5%) participants. Conclusion: women seeking legal abortion may go against their own sense of right and wrong. They deserve pre-abortion consulting to deal with conflict and negative effects in decision-making.

Abstract: 

The health of pregnant women is a fundamental aspect of healthcare and medical services. During pregnancy, which involves significant physiological and hormonal changes, this issue becomes even more critical (1). Pregnancy not only causes considerable physical changes for the mother but also places substantial stress on various organs, particularly the kidneys. This additional burden can disrupt normal kidney function and lead to severe complications that threaten both maternal and fetal health (2). Renal disease during pregnancy is a serious medical concern as it may result in life-threatening complications such as renal failure, pregnancy-induced hypertension, preeclampsia (hypertension accompanied by other symptoms during pregnancy), premature labor, and intrauterine growth restriction (3). Kidney diseases related to pregnancy often present with mild and nonspecific early symptoms that can easily be overlooked, making early diagnosis challenging. Symptoms like limb swelling, elevated blood pressure, or changes in urinary function may initially be subtle but can progress to severe complications if not diagnosed and managed promptly, posing serious risks to both mother and fetus (4). Moreover, traditional diagnostic methods -such as blood and urine tests, clinical examinations, and medical imaging- may have limited ability to detect these conditions accurately and in a timely manner. These methods often lack the capacity to predict disease progression precisely or to identify renal complications early enough, making timely diagnosis during pregnancy difficult (5). Given the critical importance of early diagnosis and prediction of kidney disease progression in pregnancy, innovative and evidence-based solutions are urgently required. In this context, modern technologies such as artificial intelligence (AI) -specifically machine learning models and artificial neural networks- have shown promise as effective and innovative tools for diagnosing and managing kidney problems in pregnant women (6). One of AI’s greatest advantages is its ability to analyze and simulate complex datasets with high accuracy and provide earlier predictions. Machine learning algorithms can process diverse data points -including blood pressure, urinary protein levels, blood glucose, blood and urine test results, genetic information, and maternal medical history- to identify patterns that indicate an increased risk of kidney problems (7). This predictive capability enables healthcare providers to identify at-risk pregnant women and implement preventive strategies to halt the progression of kidney disease. AI systems can also assist clinicians in medical decision-making by offering timely and effective treatment recommendations. Accurate identification of high-risk women is a major benefit of AI, allowing for earlier and more successful preventive and therapeutic interventions (8). To effectively apply AI for diagnosing and managing kidney problems in pregnant women, relevant medical and clinical data such as blood pressure, blood and urine test results, history of kidney disease, diabetes, urinary tract infections, and lifestyle factors must first be collected. These data are then cleansed, normalized, and divided into training and testing datasets. Subsequently, machine learning algorithms such as decision trees, random forests, and artificial neural networks are trained to detect hidden and complex patterns to predict kidney disease risk. Finally, the models are evaluated using metrics like accuracy, sensitivity, and specificity to ensure their effectiveness in real clinical settings (9). Following model development, testing and validation are essential. AI models must be assessed for accuracy, sensitivity, and specificity to determine whether they can reliably predict kidney problems. Validation uses real-world clinical and hospital data to confirm that the models perform well in practical situations (10). The adoption of AI in the diagnosis and treatment of kidney disease during pregnancy has the potential to revolutionize healthcare. This technology aids clinicians in early identification of kidney disease, enabling timely and appropriate interventions that prevent serious complications such as renal failure, preterm labor, and fetal growth restriction. Beyond improving clinical outcomes, AI application in prenatal care can reduce treatment costs and enhance the overall quality of care. Therefore, the integration of AI in this field represents a significant opportunity to optimize maternal health and reduce kidney-related complications during pregnancy, warranting serious consideration.

Abstract: 

Introduction: Abortion, a common pregnancy complication, is influenced by multifaceted reproductive, economic, social, and cultural factors. This study investigates abortion determinants among pregnant women in Khorramabad, Iran, from September 2020 to March 2021. Material & Methods: This case-control study involved 416 pregnant women (208 cases, 208 controls) selected from Khorramabad health centers through census and random sampling during the COVID-19 pandemic. Data on demographics and pregnancy history were collected using a checklist and analyzed with STATA16. Results: Among the 416 pregnant women, the mean age was 31.00 ± 5.53 years in the control group and 32.27 ± 6.85 years in the case group. Furthermore, 74 (35.58%) mothers in the case group had a diploma, 192 (92.31%) were housewives, and 106 (50.96%) had A+ blood group. The majority of mothers (46.63% in case, 39.42% in control) had an overweight range of pre-pregnancy BMI (25-29.9) (kg/m2). The mean height was 162.97 ± 5.30 in the control group and 160.86 ± 5.39 in the case group. Multiple regression logistic analysis confirmed significant associations between abortion and mother's age (OR=4.67, 95%CI=1.11-19.62), previous cesarean delivery (OR=4.33, 95%CI=1.94-9.66), not taking folic acid pills during pregnancy (OR=14.92, 95%CI=6.25-35.61), low income (OR=7.00, 95%CI=2.02-24.35), not smoking (OR=0.28, 95%CI=0.08-0.94), and absence of pre-diabetes (OR=0.13, 95%CI=0.03-0.47) (p < 0.05). No significant relationships were found between abortion and other studied risk factors. Conclusion:  Older mothers with lower income levels are more likely to experience abortion. Additionally, factors such as pre-existing pre-diabetes, previous cesarean deliveries, smoking, lack of folic acid supplementation, and maternal infections are identified as risk factors for abortion. Providing education, healthcare, and continuous support from healthcare workers can promote safe pregnancies, reduce the risk of abortion, and enhance maternal and child health outcomes.

Abstract: 

Human parvovirus B19 is a very common viral infection especially in school-aged children. The infection during pregnancy can affect the fetus due to lack of mother’s immunity. Although, there is still no evidence of fetal teratogenic effects with parvovirus B19, but non-immune fetal hydrops and abortion may be caused by vertical transmission of the virus during pregnancy. This study was aimed to assess the prevalence of parvovirus B19-specific antibody (IgM) in pregnant women who had a spontaneous abortion. This crosssectional study was carried out in all pregnant women who referred due to a spontaneous abortion. All demographic information such as age, occupation, and gestational age, last history of abortion, gravity, and presence of children below the age of six was recorded and a blood sample was provided for all the women. Then, the blood samples were tested to assay parvovirus B19-specific antibody (IgM) by EuroImmune ELISA kit. Among 94 pregnant women with the mean age of 28.4 years who had a spontaneous abortion, parvovirus B19 specific antibody (IgM) was detected in 17 participants (18.1%). Meanwhile, 14 women (14.9%) were suspected for presence of the antibody in their blood sample. There was no significant difference between the presence of antibody and age of pregnant women, occupation, gestational age, number of previous abortion, presence of children below the age of six and number of pregnancy. These findings revealed that a high percentage of pregnant women are probably non-immune against parvovirus B19, and also there might be a number of spontaneous abortions in which parvovirus infection caused fetal death. However, more studies are needed to prove the absolute role of parvovirus B19 in these abortions.

Abstract: 

Background: Health-related quality of life is affected by electromagnetic field exposure in each person everyday life. However, this is extremely controversial issue.Objective: Investigation of the associations between electromagnetic field exposure and miscarriage among women of Tehran.Materials and Methods: In this longitudinal study, 462 pregnant women with gestational age<12 wks from seven main regions of Tehran city in Iran with similar social and cultural status were participated. women were interviewed face-to face to collect data. Reproductive information was collected using medical file recorded in those hospitals the subjects had delivery. The measuring device measured electromagnetic waves, Narda safety test solutions with valid calibration date at the entrance door of their houses.Results: A significant likelihood of miscarriage in women who exposed to significant level of electromagnetic wave. However, this association was not confirmed by Wald test.Conclusion: This study may not provide strong or consistent evidence that electromagnetic field exposure is associated or cause miscarriage. This issue may be due to small sample size in this study.

Abstract: 

Background: Brucellosis is one of the most prevalent diseases common between humans and animals. It is also called Malta fever, Undulant fever and Mediterranean fever. This disease is spread by consuming milk and its unpasteurized derivatives. Clinical symptoms of brucellosis in humans are fever, chills, headache, muscular pain, tiredness, loss of appetite, joint pain, weight loss, constipation, sore throat, and dry cough. The present study aimed at surveying the seroprevalence of brucellosis in pregnant women and those women who suffered from spontaneous abortion. Methods: This case-control study was conducted in Sanandaj (Iran) in 2016 and included 2 groups of pregnant women: one group included 160 pregnant women and the other included 160 women who suffered from spontaneous abortion. Then, the participants were asked to fill out the questionnaire. After receiving permission from an obstetrician, a 10-cc blood sample was taken from each person to be used in the Rose Bengal, Wright, 2ME, and Coombs tests. Independent samples t test and Chi-square test were used to analyze the data and compare the groups. Results: Mean± SD age of women in the case group was 30. 9± 7. 3 years, while it was 27. 74± 5. 41 years in control women. The Rose Bengal, Wright, and 2ME prevalence for both groups was negative, but the Coombs and Wright tests score was 33 (20. 6%) in pregnant women and it was 27 (16. 9%) in women who experienced spontaneous abortion. No meaningful relationship was observed between spontaneous abortion and brucellosis (p= 0. 39). Conclusion: Even though the present study did not find a meaningful relationship between spontaneous abortion and brucellosis (p=0. 39), high brucella seroprevalence rates between both groups of women indicated that screening tests should be considered before gestation as an appropriate therapeutic strategy.

Abstract: 

Background: Surgical evacuation has been used as a standard treatment procedure for missed abortion, but it is an invasive technique. So medical treatments have been introduced for this problem using vaginal Misoprostol tablets. In this study we tried to evaluate misoprostol theraputic effects in patients with missed abortion, admitted in Mirza koochak Khan Hospital (2000-2001) in Tehran. Materials and Methods: In this quasi experimental study 60 patients with missed abortion were selected by simple sampling and were divided into two groups: 30 patients with amenorrhea <13 weeks and 30 patients with amenorrhea 13 weeks. 200 mcg vaginal Misoprostol was applied to posterior fornix and this was repeated every 4 hours for maximum of four doses until complete expulsion of products of conception happened. Effects and side effects of these tablets were evaluated in all patients and compared in two groups. All data were analysed using t-test and chi-square tests.Results: 40 women experienced complete abortion (63% in group 1 and 16.7% in group 2) (P<0.0001). The frequency of profuse bleeding and administration of oxytocin for control of bleeding in the group 2 (with more prolonged amenorrhea) was more than group 1 (P<0.05). Other complications including fever, diarrhea, nausea and pain appeared to be similar in two groups. Background parameters such as age, number of taken pills, and the time spent for abortion were also similar in two groups. Patients in group 2 had a higher number of pregnancies and deliveries in their history.Conclusion: Vaginal Misoprostol could be effective in the management of missed abortion specifically in patients who have had amenorrhea for less than 13 weeks. According to non-invasiveness of this method and low costs, it is recommended for missed abortions (<13 weeks) as the first - line treatment.
