Conservative management of placenta previa-percreta with bladder invasion: A case report.

Key Clinical Message: Placenta previa, accompanied by placenta percreta, which involves invasion of the bladder, presents a significant risk of excessive bleeding during and after delivery. This case highlights that prophylactic embolization, conservative surgery, and careful monitoring offer an effective approach to avoid hysterectomy in cases of placenta percreta with adjacent organ involvement. Abstract: Placenta previa complicated by placenta percreta is associated with a high risk of massive intra and post-partum hemorrhage. We present a case of a 35-year-old woman (G2 P1) who was referred to the Akbar-Abadi hospital at 13 weeks of gestation. Color Doppler ultrasound indicated complete placenta previa-percreta with bladder invasion. After induction of fetal demise, bilateral uterine and bladder artery endovascular embolization was conducted for the patient. After 48 h, under ultrasound guidance, surgical resection of residual percreta tissue was conducted as much as possible. Eight weeks later, a follow-up sonography showed the minimum residual placenta tissue and she regained menstrual cycles after 2 months. This case indicated that the combination of prophylactic embolization, conservative surgical management with placenta left in situ, and follow-up with serial color Doppler monitoring, is an optimum method to avoid hysterectomy in placenta percreta patient with adjacent organ invasion.

COVID-19 knowledge, attitudes, and practices among Iranian pregnant and postpartum women: A national study.

BACKGROUND: To control the spread of COVID-19, Iran has adopted rigorous precautionary and preventive measures, particularly for vulnerable groups. Considering the effects of knowledge and attitudes about COVID-19 on adherence to preventive measures, we examined women's knowledge, attitudes, and practices (KAP) from pregnancy to 6 weeks postpartum about COVID-19 during this pandemic. METHODS: In a cross-sectional study, 7363 women were recruited via an online questionnaire between June 23, 2021 and July 7, 2021. The questionnaire consisted of 27 questions, measuring KAP. RESULTS: Most of the participants had a good understanding of COVID-19 (Mean: 7.30 out of 9, standard deviation [SD]: 1.27), but the knowledge of the disease's main symptoms and modes of transmission was at the lowest levels. The mean attitudes score was 31.47 out of 50 (SD: 7.70). The participants had good practices against COVID-19 with a mean score of 35.48 out of 40 (SD: 3.94). To reduce anxiety and fear during the pandemic, half of our participants strongly emphasized the role of family emotional support. Income status and educational levels were the most significant variables influencing KAP (p-value ≤0.001). A correlation was found between knowledge and practice scores (r = 0.205, p-value = 0.001). CONCLUSION: Our findings may serve to formulate awareness-raising interventions and can be a guide to health policymakers and workers such as obstetricians, clinicians, and midwives for more effective educational communication emphasizing the COVID-19 symptoms and transmission modes and rendering appropriate counseling, particularly on the importance of emotional family support during the pandemic.

Cerebroplacental ratio (CPR) and reduced fetal movement: predicting neonatal outcomes.

OBJECTIVE: The aim of this study was to evaluate the role of cerebroplacental ratio (CPR) in term pregnancies with reduced fetal movements (RFM) and appropriate for gestational age (AGA)fetuses to predict poor neonatal outcomes. METHODS: A prospective cohort study was performed on 150 singleton pregnancies with gestational age of 37-41 weeks and multiple episodes of RFM (case group) and 150 pregnancies within the same criteria only without RFM (control group). Both groups had appropriate for gestational age (AGA)fetuses. Umbilical artery (UA) and middle cerebral artery (MCA) pulsatility indices (PI) were measured, and MCA to UA ratio (CPR) was calculated. Doppler indices and neonatal outcomes were compared between the two groups. Independent prediction role of CPR MoM was evaluated through a binary logistic regression method. RESULTS: The RFM group had significantly higher UA- PI MoM (1.01 ± 0.19 versus 0.86 ± 0.05, p < .001), lower MCA MoM (1.28 ± 0.20 versus 1.40 ± 0.13, (p < .001)) and lower CPR MoM (0.98 ± 0.24 versus 1.23 ± 0.12, (p < .001)) compared to the control group. Mean umbilical artery pH was lower in the RFM group and the frequency of neonatal UA cord pH <7.2 was higher in the RFM group. In RFM group, CPR MoM showed a significant linear correlation with birth weight centiles (r = 0.244, p = .003), umbilical artery pH (r = 0.319, p < .001) and Apgar score at minute 1 (r = 0.332, p < .001). CPR MoM exhibited negative correlation with duration of NICU stay (r= -0.187, p = .022). No similar correlation was observed in the control group. In binary logistic regression analysis, CPR MoM was adjusted for the results of NST; and it was concluded that CPR MoM was the only significant predictor of Apgar score minute 1 = <7 (OR: 0.004; 95% CI: 0.0002-0.0673, p < .001), umbilical artery ph <7.2 (OR: 0.019; 95% CI: 0.00005-0.0423, p < .001) and NICU admission (OR: 0.116; 95% CI: 0.018-0.744, p = .023). In multivariate binary logistic regression analysis included parity, history of abortion and ART, AFI, BPP and CPR MoM; the AFI (OR: 0.976; 95% CI: 0.957-0.995, p = .014), BPP (OR: 0.306; 95% CI: 0.172-0.545, p < .001) and CPR MoM (OR: 0.00005 95% CI: 0.000003-0.00061, p < .001) were the significant predictor of RFM. Area under the curve in receiver operating characteristics (ROC) curve was calculated as 0.828 for CPR MoM as a predictor of RFM (SE: 0.024, p < .001), yielding sensitivity and specificity estimates of 80.0% and 65.0%, respectively, using an optimal cutoff level of = < 1.19. CONCLUSION: This study concluded that reduced fetal movement was significantly related to low CPR MOM. Also, it showed the independent role of CPR MoM for prediction of lower neonatal umbilical artery pH, lower Apgar score minute 1 and higher rate of NICU admission in AGA term fetuses without considering NST results. Also, AFI, BPP and CPR MoM are significant predictors of RFM.

Comparing the efficacy of dilapan with extra-amniotic saline infusion and oral misoprostol for cervical ripening in term pregnancies.

INTRODUCTION: Labor induction is an important issue in modern obstetrics. One of the important factors for the success of induction of labor is the Bishop score of cervix. OBJECTIVE: The purpose of the present study was to evaluate and compare the efficacy of dilapan with extra-amniotic saline infusion and oral misoprostol for cervical ripening in term pregnancies. METHODS: This clinical trial study was performed on 120 nulliparous pregnant women with the Bishop score of less than 5. Group one, group two and group three received dilapan, extra amniotic saline infusion (EASI) and misoprostol respectively. All three groups were compared for duration from beginning of the intervention up to cervical ripening and Bishop Score of ≥7, duration of active phase and the second stage of labor, number of deliveries in the first 24 h, duration from beginning of the intervention up to delivery, rout of delivery as well as neonatal weight, neonatal Apgar score; hyper- stimulation, and need for oxytocin and oxytocin doses administered after 12 h of intervention. RESULTS: The number of deliveries in the first 24 h after intervention were not significantly different between the three groups. There was no significant difference between the three groups according to duration from beginning of the intervention up to cervical ripening and Bishop Score of ≥7, duration of active phase and the second stage of labor, duration from beginning of the intervention up to delivery, rout of delivery as well as neonatal weight, neonatal Apgar score; and hyperstimulation. The Bishop Score was higher in the misoprostol group 6 h after intervention [dilapan: 4.32 ± 1.38, EASI: 5.47 ± 1.28, and misoprostol: 6.72 ± 1.61 (p = .000)], Oxytocin requirement [dilapan: 38 (95%) women, EASI: 37 (92.50%) and misoprostol: 30 (75%) women, p = .013], and required dose [dilapan: 7543 ± 2465 miu/ml, EASI: 5758 ± 1615miu/ml and misoprostol: 4930 ± 2589miu/ml, p = .000] were lower in misoprostol group. CONCLUSION: Dilapan is an effective and safe method for cervical ripening in full term gestations. In cases where misoprostol and EASI cannot be used or are not desirable, dilapan can be used as an alternative.Trial registration number and registry website: IRCT20091023002624N25.

Evaluation of placental alpha microglobulin-1(PAMG1) accuracy for prediction of preterm delivery in women with the symptoms of spontaneous preterm labor; a comparison with cervical length and number of contractions.

INTRODUCTION: Since the capacity of tertiary centers is limited, identifying women with the risk of preterm delivery is crucial amongst women who refer to hospitals with threatened preterm labor. OBJECTIVE: The purpose of the present study was to evaluate the accuracy of the placental alpha microglobulin-1 (PAMG-1) test for identifying women who referred to hospitals with signs of spontaneous preterm labor and ultimately delivered within ≤48 h and ≤7 of testing and ≤37 weeks of gestation and its comparison with cervical length of <25 mm and number of contractions. MATERIALS AND METHODS: A prospective observational study was performed on women with the signs of spontaneous preterm labor. Placental alpha microglobulin-1 (PAMG-1) was evaluated in vaginal secretion. Cervical length (CL) and number of contractions were evaluated and recorded. The test to- spontaneous- delivery interval was documented. Sensitivity (SN), specificity (SP), accuracy rate of the PAMG-1, cervical length of <25 mm and number of contractions in prediction of spontaneous preterm delivery within ≤48 h, ≤7 days and preterm delivery (≤37 weeks of gestation) were calculated. RESULTS: One hundred eighty women finished the study. 44 women had positive PAMG-1 test and 58 women had cervical length of <25 mm. Women with a positive PAMG-1 were more likely to deliver within ≤48 h (p < .0001), ≤7 days (p < .0001), and before 37 weeks (p < .0001), compared to the women who had a negative test. For delivery within ≤48 h, ≤7 days and ≤37 weeks, specificity (SP) of the PAMG-1; was statistically higher than cervical length of <25 mm and contractions of 12-17/hr but not contractions of ≥18/hr. PAMG-1 showed a higher accuracy rate than cervical length of <25 mm, contractions of 12-17/hr and contractions of ≥18/hr for deliveries within ≤48 h (78.9, 55.3, 48.9, and 69.44%, respectively) and ≤7 days (76.1, 55.32, 55, and 65.56%, respectively). For deliveries before 37 weeks; the PAMG-1 test showed higher LR + than CL of <25 mm, contractions of 12-17/hr and contractions of ≥18/hr [10.24 (2.57-40.86), 2.01 (1.24-3.23), 1.30 (1.05-1.62), and 5.12 (1.24-21.11), respectively]. PPV for deliveries within ≤48 h and ≤7 days for PAMG-1 was greater than cervical length of <25 mm and number of contractions, however, NPV did not show a significant difference. CONCLUSION: PAMG-1 test showed a higher accuracy rate for prediction of delivery within ≤48 and ≤7 days in comparison with cervical length of <25 mm and number of contractions. Also, PAMG-1 test had a higher positive likelihood ratio for deliveries at ≤37 weeks. PPV for deliveries within ≤48 h and ≤7 days for PAMG-1 was greater than cervical length of <25 mm and number of contractions, however, NPV did not show a significant difference.

Effect of short-term psychological intervention on anxiety of pregnant women with positive screening results for chromosomal disorders: a randomized controlled trial.

BACKGROUND AND AIM: Prenatal diagnosis of fetal abnormalities is a critical and stressful event for women. Most pregnant women are concerned about fetal abnormalities and screening tests. Due to the importance of anxiety reduction in pregnant women, this study was conducted to determine the effect of short-term psychological intervention on the anxiety of pregnant women with positive screening results for chromosomal disorders. METHODS: A randomized clinical trial was performed on women referred to Akbarabadi Hospital in Tehran, Iran, who had positive screening results for chromosomal abnormalities. Participants were selected from eligible individuals by a continuous method and were assigned to two groups of cognitive-behavioral training (n = 46) and control (n = 46), using the block balanced randomization method. Participants in the cognitive-behavioral training group received 4 sessions of individual counseling. The control group received routine pregnancy visits. The Spielberger State-Trait Anxiety Inventory was completed before the intervention and immediately at the end of the intervention (before receiving the amniocentesis result). The analysis of intervention effects was performed as intention-to-treat and per-protocol analysis. RESULTS: There was a statistically significant difference in post-intervention state anxiety scores and trait anxiety scores (p <  0.001) between the intervention and control groups, when their means were adjusted for pre-intervention scores for both intention-to-treat and per-protocol analysis. Also, there was a large effect size between the groups in terms of state (ITT: ηp2 = 0.63, PP: ηp2 = 0.71) and trait (ITT: ηp2 = 0.72, PP: ηp2 = 0.75) anxiety scores clinically for both intention-to-treat and per-protocol analysis. The intervention group had a statistically significant and large decrease in state and trait anxiety scores from pretrial to post-trial. In contrast, the control group had a statistically significant and medium increase in state and trait anxiety scores from pretrial to post-trial. CONCLUSION: The results showed that cognitive-behavioral training reduced the anxiety of pregnant women with positive screening results for chromosomal disorders. According to the results, it is recommended to hold cognitive-behavioral training classes to reduce the anxiety of pregnant women with a positive screening result for chromosomal disorders.

Changes in pregnancy outcomes during the COVID-19 lockdown in Iran.

BACKGROUND: The Covid-19 pandemic response is influencing maternal and neonatal health care services especially in developing countries. However, the indirect effects of Covid-19 on pregnancy outcomes remain unknown. The aim of the present study was to compare pregnancy outcomes before and after the beginning of the Covid-19 pandemic in Iran. METHODS: We performed a retrospective analysis of the medical records of 2,503 pregnant women with singleton pregnancies, admitted to the maternity department of a women's hospital in Tehran, Iran, during the pre-Covid-19 pandemic (February 19 to April 19, 2019) and the intra-Covid- 19 pandemic (February 19 to April 19, 2020) period. RESULTS: We included 2,503 women admitted to the hospital; 1,287 (51.4 %) were admitted before the Covid-19 lockdown and 1,216 (48.6 %) during the Covid-19 lockdown. There were no significant differences in stillbirth rates (p = 0.584) or pregnancy complications (including preeclampsia, pregnancy-induced hypertension and gestational diabetes) (p = 0.115) between pregnant women in the pre- and intra-pandemic periods. However, decreases in preterm births (p = 0.001), and low birth weight (p = 0.005) were observed in the pandemic period compared to the pre-pandemic period. No significant difference in the mode of delivery, and no maternal deaths were observed during the two time periods. CONCLUSIONS: In our study we observed a decrease in preterm births and low birth weight, no change in stillbirths, and a rise in the admission rates of mothers to the ICU during the initial Covid-19 lockdown period compared to pre-Covid-19 lockdown period. Further research will be needed to devise plan for immediate post-pandemic care and future health care crises.

The role of leukemia inhibitory factor in pathogenesis of pre-eclampsia: molecular and cell signaling approach.

Endothelial dysfunction is considered as the main hallmark of Preeclampsia (PE). Despite the unknown pathogenesis of PE, different possible causes have been suggested in various studies. In this review, we first studied the Leukemia inhibitory factor (LIF) role in the related pathways to the PE pathogenesis, such as inflammation, endothelial dysfunction and hypertension. LIF can increase the expression of ICAM-1 and VCAM-1 via the JAK/STAT3 pathway, thereby inducing inflammatory responses and endothelial dysfunction. It can also be involved in the vascular vasoconstriction and hypertension by reducing the nitric oxide (NO) synthesis. Identifying the link between LIF and pathways associated with PE pathogenesis could be effective to achieve an effective PE treatment in the future.

The Impact of COVID-19 Pandemic on Stress and Anxiety of Non-infected Pregnant Mothers.

BACKGROUND: The newly emerging COVID-19 has caused severe anxiety around the world and it is infecting more people each day since there is no preventive measure or definite therapy for the diseases. The present study aimed to evaluate its effect on anxiety and stress of pregnant mothers during perinatal care. METHODS: Three-hundred pregnant mothers without COVID-19 infection who were referred to the hospitals affiliated to Iran University of Medical Sciences for delivery during April 2020, based on negative clinical symptoms and the results of polymerase chain reaction (rt-PCR) for COVID-19, were recruited by census method and asked to complete the Persian version of the perceived stress scale (PSS); participants views about their anxiety level and the role of COVID-19 as the source of their stress and worries were recorded. Women who refused to continue the study were excluded. The frequency of variables and mean scores were calculated using SPSS v. 21. RESULTS: Mean age of mothers was 30.20±16.19 years; 31.3% were primigravida and mean gestational age was 38.00±4.14 weeks. Moreover, 16.3% asked for earlier pregnancy termination and 39% requested Cesarean section (C/S). Assessing the mothers' anxiety revealed a high/very high level of anxiety in 51.3%. The majority felt worried and frustrated because of COVID-19 (86.4%). Social media had a great impact on the level of stress among these mothers (60.3%). CONCLUSION: COVID-19 pandemic is an important source for the increased anxiety and stress among healthy pregnant mothers.

The comparison of the effect of soybean and fish oil on supplementation on menopausal symptoms in postmenopausal women: A randomized, double-blind, placebo-controlled trial.

BACKGROUND: The effect of soybean and omega-3 fatty acid supplementation on menopausal symptoms in postmenopausal women was investigated. MATERIALS AND METHODS: In a randomized, double-blind, placebo-controlled trial postmenopausal women were randomly given either soybean (Soygan 500 mg capsule; n = 60), or omega-3 fatty acids (Omega-rex 1000 mg soft gel; n = 60), or placebo (n = 60) daily for 12 weeks. The primary outcome was a change on the menopause rating scale score (MRS), while the secondary outcome was any adverse symptoms and effect was effect of soybean or omega-3 fatty acid supplements on the blood lipids and thyroid hormone. RESULTS: Based on the results of post-hoc in terms of overall MRS score there was a significant difference between the control and Soygan (p < 0.001) and Omega-rex groups (p = 0.03); however, there was no significant difference between the two intervention groups (p = 0.86). Soygan and Omega-rex had no effects on the blood lipids and thyroid hormone. CONCLUSION: Soygan and Omega-rex reduced the MRS score and improved menopausal symptoms in postmenopausal women.

Comparison between two doses of betamethasone administration with 12 hours vs. 24 hours intervals on prevention of respiratory distress syndrome: a randomised trial.

The purpose of the present study was to compare the effect of a two-dose administration of betamethasone with 12 hours interval vs. 24 hours interval on neonatal respiratory distress syndrome (RDS). The study was performed as a randomised clinical trial on 201 pregnant women with a gestational age of 26-34 weeks. In one group 12 mg of betamethasone every 12 hours for two doses and in the other group 12 mg of betamethasone every 24 hours for two doses were prescribed intramuscularly. There were no significant differences between the two groups according to maternal age, parity, gravidity, BMI, neonatal sex, need to surfactant, NICU admission, NICU stay, neonatal death, neonatal sepsis and Apgar score at minutes 1 and 5, but the gestational age at the beginning of the study and delivery receiving complete course of betamethasone and neonatal weight were lower in 24 hours group. RDS, necrotising enterocolitis, intra-ventricular haemorrhage and chorioamnionitis were more in the 24 hours' group. Multiple regression analysis showed that RDS and IVH (p = .022, RR = 0.07, CI95% 0.006-0.96 and p = .013; RR = 0.9, CI95% 0.1-0.89, respectively) were more in the 24 hours group and neonatal death (p = .034, RR = 4.7, CI95% 1.07-16.2) and NEC (p = 0.038, RR = 2.5, CI95% 1.7-3.7), were more in the 12 hours group. In conclusion, it seems that 12 hours interval betamethasone therapy may be considered as an alternative treatment in the case of preterm labour for acceleration of lung maturity; however, it is suggested that more studies should be performed on this issue and various morbidities. IMPACT STATEMENT What is already known on this subject: Administration of a single course of corticosteroids in all women with a gestational age of 24-34 weeks of pregnancy who are at risk for preterm labour and delivery has been recommended. The accepted regimen by National Institutes of Health (NIH) is an injection of betamethasone for two doses with 24 hours interval. What do the results of this study add: Twelve hours interval betamethasone therapy may be considered as an alternative treatment in the cases of preterm labour for acceleration of lung maturity. What are the implications of these findings for clinical practice and/or further research: Prescription of two doses (complete regimen) is more important than the interval between two doses for obtaining the maximum effect in a preterm birth.

A comparison between the effects of ginger, pyridoxine (vitamin B6) and placebo for the treatment of the first trimester nausea and vomiting of pregnancy (NVP).

INTRODUCTION: Nausea and vomiting of pregnancy (NVP) are one of the most common complains of the early pregnancy period and are bothersome for pregnant women. Some prefer to use herbal medicine instead of chemical agents. OBJECTIVE: The purpose of the present study was to compare the effects of ginger, pyridoxine (vitamin B6), and placebo for the treatment of NVP. METHOD: The study was performed as a triple blind clinical trial on pregnant women suffering mild to moderate NVP between 6 and 16 weeks of pregnancy. In these women ginger, 500 mg twice daily, vitamin B6 40 mg twice daily and placebo twice daily were administered for 4 d. Rhodes questionnaire was used for evaluation of the severity of symptoms. The severity of NVP was evaluated 24 h before entering the study and up to 4 d after using medications and results were compared among the three groups. RESULTS: Seventy-seven women finished the study (28 in the Ginger group, 26 in the B6 group, and 23 in the placebo group). The women of the three groups did not have significant differences according to age, gestational age, parity, and severity of each symptom before treatment and educational status. Total score of Rhodes questionnaire for nausea was decreased significantly in three groups after treatment. (p < .001, p = .012, and p = .03 for ginger, vitamin B6, and placebo, respectively.) Also total score of Rhodes questionnaire for vomiting was decreased in three groups (p = .03 for ginger, p = .02 for B6, and p = .04 for placebo). Ginger and vitamin B6 could reduce the severity of all items of Rhodes questionnaire significantly; however, placebo was significantly effective only on the frequency of nausea, intensity of vomiting and frequency of retching. Ginger and vitamin B6 were more effective than placebo (p = .039 and p = .007, respectively); however, total score of Rhodes did not show significant difference between ginger and vitamin B6 (p = .128). Ginger was more effective for nausea (intensity and distress) and distress of vomit. CONCLUSION: Ginger is more effective than placebo for the treatment of mild to moderate NVP and is comparable with vitamin B6. Trial registration number and registry website: IRCT2015020320923N1.

Prevalence of positive recto-vaginal culture for Group B streptococcus in pregnant women at 35-37 weeks of gestation.

BACKGROUND: Recto-vaginal colonization of Group B streptococcus (GBS) has been known as an important issue in mother and newborn's health, which is getting frequent in developing countries. Screening test have been introduced and utilized in many countries and is recommended by many researchers. However, due to lack of information in prevalence of GBS, especially in Iran, there are doubts and controversies regarding whether it is necessary to execute any effort to run screening tests. The aim of this study is to determine the prevalence of positive recto-vaginal culture for GBS in pregnant women between 35-37 weeks of pregnancy in Tehran. METHODS: In this cross-sectional study, pregnant women in 35(th)-37(th) week of pregnancy were included. All hospitals in Tehran, Iran, were stratified and clustered, and the sampling was done randomly. All recto-vaginal samples were referred to Firoozgar Hospital's pathology laboratory in less than an hour and the results were reported afterwards. Other demographic information and pregnancy and neonatal-related complications such as previous pre-term delivery, PROM (Premature rupture of membrane) and neonatal sepsis and maternal infection were evaluated. RESULTS: The prevalence of positive GBS cultures was 22.76% (234 Out of 1028). No significant difference was found in positive cultures with mother's age, educational level, and history of pregnancy, maternal complications, and previous neonatal sepsis. CONCLUSION: Due to similar results with other countries, recto-vaginal GBS culture screening is recommended in Iranian urban pregnant women regarding high prevalence and higher neonatal complication.
