Background: Due to the uncertainties of maternal and neonatal complications after delivery and the lack of similar studies in this regard, this study aimed to compare the maternal and fetal complications of vaginal birth after C-Section (VBAC), natural delivery and repeat Cesarean section in Isfahan province.Method: In this one-year descriptive cross-sectional study, 49889 pregnant women who had the natural childbirth (29631 deliveries), elective repeat Cesarean section (20148 deliveries) and VBAC delivery (110 deliveries) were enrolled, then maternal and neonatal complications were compared in three groups.Results: There was a significant difference between the three groups based on the maternal and neonatal outcome, Apgar scores in the first and fifth minutes after delivery and the need for resuscitation at birth (P <0.05). Neonatal outcome was better in natural delivery and then VBAC compared to repeat C-section, respectively. Maternal outcome was better in VBAC and then repeat C-section than the natural childbirth, Apgar scores in the first and fifth minute were better in VBAC, and later natural delivery than repeat C-section and resuscitation at birth demonstrated better results for natural delivery and then VBAC than repeat C-section.Conclusion: Utilizing VBAC and natural delivery have better maternal and fetal outcomes compared to C-section along with being more satisfactory and safer.

Several studies have described multisystem inflammatory syndrome (MIS) in children, but very few investigations presented this syndrome among neonates (MIS-N). The present study has reviewed the current knowledge about MIS-N, its etiology, symptoms, and outcomes to attract special attention with an eye on earlier diagnosis and treatment of newborns affected by perinatal SARS-CoV-2-infection. A narrative review study was conducted (Tehran, Iran, 2021). All types of full English articles (up to October 1 2021) were included. Detailed research on academic search engines was performed. The implemented Mesh-based keywords were "SARS-COVID-2" OR "COVID-19" OR "coronavirus" AND "Neonate" OR "Neonatal" OR "Newborn" AND "Multisystem Inflammatory Syndrome" OR "MIS-N" OR "inflammatory response syndrome" AND "Pregnancy" OR "Perinatal" OR "prenatal". Finally, 15 Full-text articles were included that met the eligibility criteria. Available data related to the disease, its etiology, presentations, and its outcome were collected and discussed. The cause of MIS-N is the transmission or production of SARS-CoV2 antibodies in response to SARS-CoV2 infection. By involving different organs, the clinical manifestations of MIS-N may mimic sepsis, toxic shock syndrome, RDS, Kawasaki disease, necrotizing enterocolitis, myocarditis, meningitis/encephalitis, aortic thrombosis, ETC. Besides the clinical presentations, detecting reactive anti-SARS-CoV-2 IgG antibodies could be a notable clue in MIS-N diagnosis. Supportive therapy, suppressing the autoimmune and inflammatory responses, anti-platelet agents, and anticoagulants were reported as effective therapeutic agents to improve the outcome. The present study highlighted the possibility of MIS-N as an infrequent but severe syndrome consequent to perinatal COVID-19 infection. Although the diagnosis is still controversial, clinical suspicion, laboratory findings, and early treatment initiation could improve the outcome of this immunological disease.

Background & Objective: The thymus gland significantly affects fetal immune system maturation. Additionally, there is a linear association between thymus gland size and its performance. Given the high prevalence of vitamin D deficiency in Iran and scarce studies with conflicting results, subjecting maternal vitamin D concentration effect on fetal thymus, we decided to investigate maternal vitamin D concentration and its relation to fetal thymus size in mid-gestation. This study also aimed to generate a race-specific reference range.Materials & Methods: We performed a cross-sectional study of ultrasound measurements of the fetal thymus at 18-22 weeks of gestational age in 94 pregnant women and its correlation with maternal serum vitamin D levels from May to July 2021 at the tertiary center of Imam Khomeini Hospital in Tehran, Iran.Results: The mean values of thymus perimeter, thymus-thoracic ratio, thymus transverse diameter, and thymus area in all participants were 4.18±0.56 cm, 0.37±0.04, 1.56±0.21 cm, and 1.11±0.76 cm2, respectively. There was a trend toward decreased thymus perimeter and transverse thymus diameter with decreasing level of maternal vitamin D. There was also a significant correlation between thymus perimeter and transverse thymus diameter with fetal biometric indices and gestational age. Furthermore, a significant correlation was observed between the thymus perimeter and transverse thymus diameter. Conclusion: We generated a race-specific nomogram for fetal thymus size in Iranian pregnant women. Moreover, the observed trend toward decreased fetal thymus size with decreasing maternal vitamin D levels requires further prospective investigations. A high prevalence of vitamin D deficiency and low compliance with daily vitamin D intake during pregnancy was also shown, which requires a solution.

Background & Objective: There are a lot of apps for pregnancy care using mHealth technologies. However, it has not been studied which criteria in these apps are essential for increasing the quality of these mHealth programs in pregnant women. Thus this study aimed to review the desirable features of mobile-based pregnancy care applications and provide a model to evaluate existing applications.Materials & Methods: Features of a mobile-based pregnancy app were designed using a qualitative approach. In this research, an open questionnaire was developed. Obstetricians and gynecologists filled out this questionnaire. After thematic analysis of the questionnaires, the obtained items are embedded into a general framework for evaluation mHealth.Results: Fifteen gynecology and obstetrics experts participated in this study. Eight themes were obtained from 34 items mentioned by the experts. Finally, a specialized framework for evaluating mHealth apps for pregnancy care is proposed. Conclusion: To design mobile-based pregnancy care app and evaluate the existing apps in the field of pregnancy, the provided indicators can be used. This framework and other similar specialized frameworks could be developed to improve the quality of the mHealth apps.

Background & Objective: The aim of this study was to evaluate the effectiveness of adjunctive pessary therapy after cerclage in increasing the gestational age (GA) to 37 weeks in women with cervical insufficiency (CI).Materials & Methods: This randomized controlled trial (RCT) was conducted at the infertility department of Royan Institute, Tehran, Iran. A total of 170 singleton pregnant women aged 18-42 years old, diagnosed with CI by GA 14-24weeks, who had intact membrane with no signs of intrauterine infection, vaginal bleeding, or uterine contraction, were enrolled. Patients were randomized 1:1 to receive either cervical cerclage or pessary after cerclage. The primary outcome was spontaneous preterm birth (SPB) (<37weeks). The secondary outcomes were GA at the time of delivery, SPB (less than 34, 32 & 28 weeks), delivery method, neonatal outcomes, maternal adverse events, and maternal satisfaction with the intervention.Results: The incidence of SPB (<37, 34, 32 & 28weeks), method of delivery, GA at time of delivery, and neonatal outcomes were not significantly different between the two groups. The incidence of vaginal bleeding (P < /i>=0.007) and pelvic pain (P < /i>=0.03) significantly was less in the intervention group. The mean score of satisfaction in the intervention group was significantly higher than the control group < /span> (P < /i>=0.01). Conclusion: The placement of an adjunctive pessary for pregnant women with singleton pregnancy and CI, did not result in a lower rate of SPB (<37weeks) compared to cerclage alone. However, pregnancy complications after the intervention until delivery were less in these women, while the level of satisfaction was higher.

Background & Objective: This study aimed to compare the neonatal outcomes and infant development one year after birth at different gestational ages of elective cesarean section (CS) beyond 38 weeks.Materials & Methods: This retrospective cohort study was recruited in an academic hospital affiliated with Tehran University of Medical Sciences between June 2018 and June 2020. The subjects of the study were the women who were scheduled for elective CS and divided into 3 groups according to the gestational age (38 0/7 to 38 6/7 as group A, 39 0/7 to 39 6/7 as group B, and 40 0/7 to 40 6/7 as group C). The neonatal outcomes and the growth and development status were evaluated by ages and stages questionnaires® (ASQ) after 12 months and compared between groups.Results: Totally, 952 neonates were eligible for this study. In groups A, B, and C, CS was performed in 314, 409, and 229 neonates, respectively. The first minute Apgar was significantly lower in the neonates with lesser gestational age at delivery (P < /em>=0.026). Indeed, neonatal hospitalization, hypoglycemia, and jaundice in group A were significantly higher than in other groups (P < /em><0.001). Regarding psychomotor development, the scores related to gross motor and problem-solving abilities in group A were significantly lower than those in other groups (P < /em><0.05).Conclusion: It is suggested to plan elective CS beyond 39 weeks of gestation to decrease prenatal morbidities and improve psychomotor development one year after birth.

Background & Objective: This study assessed the relationship between the ratio of fetal lung volume to head circumference and amniotic fluid index (AFI) in the third trimester of pregnancy.Materials & Methods: This prospective study was performed on low-risk pregnant women in their third trimester of pregnancy. Fetal lung volume was determined separately using the lung-to-head ratio (LHR) for the right and left lungs. Moreover, the AFI was evaluated, and the Pearson correlation coefficient between LHR for both lungs and AFI was investigated.Results: Overall, 112 pregnant women were included in the study. The mean ± standard deviation (SD) of fetal Observed/Expected Right LHR (O/E RLHR) and O/E Left LHR (O/E LLHR) were 113.9±0.36 and 97.13±27.87, respectively. The mean ± SD of AFI was 12.5±4.96 cm. Pearson correlation coefficient did not show a significant relationship between AFI and the left and right LHR (P < /em>>0.05). However, O/E RLHR was significantly correlated with abdominal circumference (P < /em>=0.02, r=0.2), gestational age (P < /em>=0.21, r=0.27), and fetal weight (P < /em><0.001, r=0.27). There was a positive correlation between the number of days the infant was admitted to the neonatal intensive care unit and the volume of the right lung of the fetus (P < /em>=0.03, r=-0.2). No correlation was observed between fetal parameters and the volume of the left lung of the fetus.Conclusion: The results of this study showed that AFI in the third trimester of pregnancy was not significantly correlated with LHR.

Background & Objective: IUGR (intrauterine growth restriction) fetuses have been known as a significant concern in clinical practice. It is associated with fetal mortality and morbidity and prenatal adverse cardiac remodeling. The aim of this study is the evaluation of the relation between MPI (myocardial performance index) abnormalities and doppler findings in both normal and IUGR fetuses.Materials & Methods: In this cross-sectional study, 400 consecutive pregnant women in Shariati Hospital, Tehran, Iran, in 2019 and 2020 underwent ultrasound assessment at 28-40 weeks, in which among the 400 performed ultrasounds, 47 fetuses with IUGR were selected as a case group, and 47 fetuses with normal weight were selected based on AGA (appropriate gestational age). Cardiac function was evaluated by measuring MPI in diastolic and systolic function in two groups. The results were compared to the IUGR (case group) and control group by SPSS software version 20.Results: In receiver operating characteristic (ROC) analysis, the AUC (area under the curve) for left ventricular MPI (LV MPI) was 0.929 (CI95%: 0.868-0.991; P < /em>=0.001), and the sensitivity and specificity values were 87% and 69.4% with a cut-off point of 0.2850. In ROC analysis, the area under the curve for RV MPI was 0.842 (CI95%: 0.741-0.942; P < /em>=0.001), and the sensitivity and specificity values were 78.3% and 63.9%, with a cut-off point 0.2850. Left and right ventricular MPI showed a significant difference statistically between the case and the control groups.Conclusion: The study showed a significant rise of MPI in IUGR fetuses. MPI can be considered as a useful parameter for evaluating the severity of growth restriction in IUGR fetuses.

Pregnant women are at higher risk of severe COVID-19 than the general population. Furthermore, COVID-19 increases the preterm and cesarean rates due to maternal and fetal complications. Owing to the adverse effects of the COVID-19 on pregnant women, in-person prenatal visits face challenges. Thus, alternative solutions that reduce the number of visits while preserving maternal and fetal care quality should be considered. Digital health is one of the potential solutions. Obstetricians and gynecologists, and other clinical experts should cooperate to define digital tools’ requirements and standards for prenatal care. Moreover, governments and healthcare insurances should facilitate the coverage of provided services’ costs by digital health tools, especially in developing countries.

Background & Objective: Pregnancy is a stressful event in and of itself, which may have an impact on the present prevalence of COVID-19 illness. It is crucial to think about what factors can help pregnant women cope with the anxiety brought on by the COVID-19 outbreak. The purpose of this study was to determine the prevalence of COVID-19 in pregnant women, as well as the impact of COVID-19 anxiety on pregnant women's Apgar scores and birth weights of newborns.Materials & Methods: From early January to late March 2021, 102 pregnant women were included in this descriptive cross-sectional study using any accessible sampling method. Questionnaires such as the "Demographic" and "Corona Anxiety Scale" were used to collect data. SPSS software version 22 was used to analyze the data.Results: The mean score of total anxiety caused by COVID-19 in pregnant women was 20.88 ± 21.08, which was moderate. Among the components of anxiety, the mean score of psychological symptoms (13.05 ± 5.31) of pregnant women was higher than physical symptoms (5.64 ± 5.72). There was no statistically significant link between demographic characteristics and COVID-19-induced anxiety (P < /em>>0.05). The findings also revealed no statistically significant connection between COVID-19-induced anxiety and newborn weight or Apgar score 1 and 5 minutes after birth (P < /em>>0.05).Conclusion: The definitive incidence of COVID-19 in pregnant women was low. They experienced a moderate level of anxiety caused by COVID-19, which requires the necessary measurements to be taken by the relevant authorities, family and others to reduce this anxiety during the coronavirus pandemic.

Background & Objective: Nucleated red blood cells (NRBCs) enter the circulation in response to hypoxia, but it remains unknown how physiological delivery without fetal distress can change the NRBC level. Accordingly, in the present study, we compared the mean NRBCs per white blood cell (WBC) in the umbilical cord of normal vaginal delivery (NVD) with cesarean section (C/S). To compare the mean NRBCs per WBC within umbilical cord in normal term newborns who were born by NVD with those delivered by C/S. Methods: This case-control study was conducted for 305 neonates in two different groups, i.e., NVD (case) and C/S (control) groups. The blood samples were taken from umbilical veins to evaluate fetal NRBCs and WBC count after recording their demographic characteristics. Finally, all data were assessed using SPSS 16.Results: The average age of mothers was 25.79±5.35 years. The average Apgar score of neonates was 8.23±0.6. The average NRBC count was 4.63±5.2. There was no significant difference in maternal age, parity, neonatal weight, and NRBC count per 100 WBCs between the two groups. Conclusion: In the present study, the mean NRBC count within the umbilical cord of neonates born by elective C/S was less than those delivered by NVD, although this difference was not significant.

Pregnant women appear to be more severely affected by COVID-19. Coagulopathy is known as one of the most challenging effects of COVID-19, and the effects of acute airway diseases resulting from the coronavirus on pregnant mothers and their fetuses can be dangerous. Two women who where pregnant suffering from coagulopathy (one of them with disseminated intravascular coagulation (DIC) and the other one with hypercoagulation) and COVID-19 infection are reported in this study. During hospitalization due to severe vaginal bleeding and placental detachment, cesarean section was performed on the first caseand because of acute severe DIC, she received a massive transfusion. The second patient epigastric pain and tachycardia. COVID-19 might have a variety of effects on pregnancy outcome, from vascular and placental involvement to respiratory involvement; there is an association between the coronavirus and hyper-coagulopathy state and coagulopathy like DIC.

Background & Objective: Gestational diabetes mellitus (GDM) is the most prevalent disorder during pregnancy, which is the result of insulin resistance and hyperinsulinemia due to the secretion of placental diabetogenic hormones. This study aimed to investigate the utility of glycated hemoglobin A1c (HbA1c) alone and in combination with hematocrit for early detection of gestational diabetes mellitus.Materials & Methods: In this prospective cohort research, 373 pregnant women who referred to prenatal clinics were included. Hematocrit and HbA1c were determined at gestational age of 12 to 16 weeks and compared with the oral glucose tolerance test (OGTT) results at gestational age of 24-28 weeks.Results: The best cut-off hematocrit for determining pregnancy diabetes mellitus was 37.3. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were 70.15%, 64.12%, 32.71 %, and 89.51% respectively.In terms of HbA1c, the best cut-off value to determine GDM in pregnant women was 5, with a sensitivity of 98.51%, specificity rate of 99.02%, PPV of 95.07%, and NPV of 99.49%. In terms of diagnosing GDM, the area under the ROC curve (AUC) for HbA1c was equal to 0.985 which was higher than the AUC for the combination of HbA1c with HCT.Conclusion: Measuring HbA1c can be useful as a screening test for GDM, which is an inexpensive and available test. The combined evaluation of HbA1c and hematocrit did not improve the diagnostic value of HbA1c in GDM screening compared to exclusive evaluation of HbA1c.

Background & Objective: Since the first reported respiratory distress syndrome due to the new version of the coronaviruses family, COVID-19, there is a concern about the possible maternal and perinatal outcome of new infection in a short and even long time, our information about the prognosis of pregnancy in sync with COVID-19 is limited. What is our task as scientists in eliminating the unknown facts?Materials & Methods: Here we try to present a couple of pregnant cases in their third trimesters of pregnancy that complicated with two contrary complication of COVID-19 infection, intending to illuminate the best management strategy in COVID-19 infected pregnant.Results: The first case had experienced thromboembolism, and also bleeding accident, who fortunately survived unlike the other case, who expired due to multi-organ failure and impossibility of anticoagulant agent administration for the suspected pulmonary thromboembolic accident.Conclusion: The prior report revealed the thrombo-inflammatory and hypoxic effect of COVID-19 that could lead to microvascular thrombosis and progression, which enforce health care providers, introducing the anticoagulant agents to decline COVID-19 mortality, especially in a critically ill patient. Pregnancy is associated with coagulation abnormality which could intensify the COVID-19-induced coagulopathy. But, one should balance the harm and benefit of such a hazard approach, is there any concern about vascular damage of COVID-19 and subsequent bleeding, that could be exacerbated with high dose anticoagulant agent administration? The other question that we want to discuss in the present report is about comparing the cost and benefit of anticoagulant therapy?

Background and Objective: Asthma is the most common chronic respiratory disorder during pregnancy and it may affect pregnancy outcomes. This study aims to compare the pregnancy, delivery and neonatal outcomes between asthmatic and non-asthmatic pregnant women.Methods: The study was designed as a historical cohort among pregnant women with and without asthma. A total number of 583 asthmatic patients were allocated to the case group and 753 women without asthmatic history were placed in the control group. Pregnancy, labor and neonatal outcomes were compared between the two groups.Results: The baseline characteristics of the women in both groups did not show significant differences. Gestational hypertension was more in the asthmatic group [43 (7.37%) VS 26 (3.45%), P < /em>=0.001]. Also the rate of preterm delivery was higher in asthmatic women [72 (12.34%) VS 77 (10.22%) in the control group, P < /em>=0.04]. However, the rate of preeclampsia was less in the asthmatic group [29 (4.97%) VS 71 (9.42%), P < /em>=0.008]. Apgar score at minutes 1 and 5 was less in asthmatic group. Intra Uterine Fetal Demise (IUFD) [24 (4.1%) VS 13(1.7%), P value=0.009], and neonatal death [31 (5.31%) VS 10 (1.32%), P < /em>=0.001] were more in the asthmatic group. The maternal and neonatal complications did not show significant differences in various severities of asthma. Multivariate regression model showed more risks for neonatal death [adjusted odds ratio (AOR)=4.18; CI95% 2.03-8.60], IUFD (AOR=2.43; CI95% 1.22-4.82), gestational hypertension (AOR= 1.43; CI 95% 1.40-1.45), and lower risk for preeclampsia (AOR 0.37; CI95%0.17-0.79) in asthmatic women.Conclusion: Regardless of the fact that asthmatic mothers had higher frequencies of gestational hypertension, IUFD and neonatal death, the effect of asthma on perinatal outcome is minimal, probably because of efficient medical control.

Background & Objective: This study aimed to assess the effect of betamethasone on neonatal and maternal complications of late preterm labor. Materials and Methods: The women at the gestational age of 34 weeks to 36 weeks and 6 days who referred to Shahid Motahari Hospital, Urmia, Iran for premature labor or had a maternal indication of pregnancy termination were selected for this study. The participants were classified into the case group receiving two doses of 12 mg intramuscular betamethasone every 24 h or the control group who did not receive betamethasone. The incidence of respiratory distress syndrome (RDS), need for mechanical or noninvasive ventilation, days of stay in Neonatal Intensive Care Unit (NICU) or Neonatal Ward, umbilical arterial blood gases, maternal hyperglycemia, and wound infection were evaluated.Results: A total of 200 pregnant women were enrolled with a mean age of 27.06±6.55 years. Out of 200 neonates, 52 cases had RDS of which 21 received betamethasone. The first-minute Apgar score was 6.96±0.75 in the control and 7.57±0.67 in the case groups (P < /em><0.001). The incidence of RDS, need for surfactant administration, noninvasive ventilation, and days of stay at NICU or Neonatal Ward were significantly different between the study groups. However, because of the low number of cases (2 cases), we did not find a significant difference in the need for mechanical ventilation between the two groups (P < /em>=0.041). There was maternal hyperglycemia in 65% of women in the test group. Conclusion: Administration of betamethasone in late premature pregnancies can be effective in the reduction of neonatal complications without any increase in maternal complications.

Background and Objectives: Maternal serum levels of the first- and second-trimester markers for aneuploidy have been revealed to be associated with adverse pregnancy outcomes in the absence of neural tube defects or aneuploidy. This finding can guide clinicans for early diagnosis and management of such outcomes. However, previous finding are conflicting in this regard. Therefore, this study evaluated the detection of adverse pregnancy outcomes by first- and second-trimester serum screening analytes.Methods & Materials: We prospectively recruited 972 females who underwent first and second-trimester aneuploidy screening. We gathered information on maternal demographic characteristics and serum biomarkers (free B-hCG and PAPP-A for the first-trimester; AFP, Β-hCG, Inhibin-A, and unconjugated estradiol for second-trimester). At the end of the study, adverse pregnancy outcome was recorded.Results: Abnormal screening results were reported in 34 (3.5%) patients. Two groups were significantly different in maternal age, BMI, and gestational period (P < /em>=0.017, 0.003 and 0.021, respectively). Among the measured adverse outcomes, preeclampsia was significantly more prevalent in the case group (P < /em><0.0001). Abnormal levels of Inhibin-A is associated with the incidence of preeclampsia (RR: 29.87, CI: 13.22-67.49, P < /em><0.0001). Additionally, patients with an abnormal level of Inhibin-A had a shorter gestational period (255.5 ± 24.53 vs. 264.79 ± 8.99, P < /em>=0.006). Likewise, patients with an abnormal level of maternal serum alpha-fetoprotein (MSAFP) had a shorter gestational period (252.0 ± 29.3 vs. 264.8 ± 8.93, P < /em>=0.001).Conclusion: First- and second-trimester maternal serum biomarkers could provide a possible screening tool for early detection of preeclampsia.

Background & Objective: Gestational hypertension (GH) is considered as one of the important health-related issues of pregnant women. One of the raised problems in the pathogenesis of GH is obstructive sleep apnea (OSA). This study aimed to evaluate associated factors of OSA among an employed pregnant population.Materials and Methods: In this study, 200 employed pregnant women with GH as the case group and 200 healthy pregnant ones as the control group were enrolled. Blood pressure >140/90 after 20 weeks of gestational age without proteinuria was defined as GH. Chi-square and Mann-Whitney tests were applied for statistical analysis.Results: Mean ± SD of age and body mass index (BMI) were 32.85 ± 5.45 (years) and 31.85±5.97 (kg/m2) among the case group, respectively. Participants with GH had higher mean BMI, neck circumference, and more frequency of snoring than the control group, which was statistically significant (P < /em><0.012, P < /em><0.025, and P < /em><0.007, respectively). Sales and service occupations consisted the group with the highest frequency of GH.Conclusion: Participants with GH had higher BMI, snoring, observed apnea, and neck circumference. This observation warrants comprehensive assessment of OSA and related risk factors among patients with GH.

Background & objective: Premature preterm rupture of membrane (PPROM) is a cause of preterm birth. This study investigated the effectiveness of Doppler ultrasound in predicting fetal complications and neonatal outcomes of pregnant women with PPROM.Materials & Methods: In this cross-sectional study, a total of 23 pregnant women with PPROM were chosen in their 24 to 34 weeks of gestational age. The fetuses’ blood flow indices were evaluated by Doppler ultrasound pulsatility index (PI) in the middle cerebral, main pulmonary, right kidney, and fetal umbilical arteries and descending aorta at admission (because of PPROM) and 24 hours before delivery. Neonatal outcomes were assessed within the first week of birth.Results: The kidney artery PI increased (P < /em>=0.047) and pulmonary artery PI decreased (P < /em>=0.024) at pregnancy termination time. There was a negative correlation between the 5-minute Apgar score and fetal umbilical artery PI at admission (P < /em>=0.003) and pregnancy termination times (P < /em>=0.031). The fetal umbilical artery PI of neonates with abnormal brain ultrasound imaging results significantly decreased at admission (P < /em>=0.002) and pregnancy termination times (P < /em>=0.004).Conclusion: Fetal artery Doppler ultrasound PI may be a valid tool for predicting neonatal outcomes of women with PPROM.

Background & Objective: Screening tests for common aneuploidy, especially trisomies 21, 18, and 13, should be offered to pregnant people of all ages at first and second trimesters. Theses include combined tests (nuchal translucency (NT)+biochemical pregnancy-associated plasma protein-A (PAPP-A), free beta-human chorionic gonadotropin (β-hCG)) and quad test. If the tests are positive based on cut-off value of 1:250, diagnostic tests such as amniocentesis and chorionic villus sampling (CVS) are suggested. The current study aimed to comparatively evaluate the results of these screening tests and amniocentesis.
Materials & Methods: This practical-basic study was designed to evaluate the accuracy of first and second trimester screening tests with amniocentesis results. A total of 45 subjects were selected from the patients referred for abnormal screening tests toShohadaya-ye-Tajrish hospital in Tehran, Iran, during 2014-2015. The results of tests (combined or quad) were positive based on cut-off value of 1:250. Data was collected through a questionnaire containing such information as age, gravidity, previous aneuploidy births, placenta location, blood group, amniotic fluid color, type of sampling needle, and mode of needle entrance.Results: The mean age of patients was 33.16 years. There was significant p-value between positive results of amniocentesis and age of the patients. Out of 45 amniocentesis tests, four had abnormal results (two in the first trimester (2/17) and two in the second trimester (2/24)). Also, three items were T21 and the forth was translocation between chromosome 11-22. We had one fetal loss due to amniocentesis procedure.Conclusion: Diagnostic tests are suggested for better evaluation of abnormal results. These screening tests have false positive and negative results. We attempted to evaluate the real results with invasive tests. Further research is needed to investigate the accuracy of screening aneuploidy tests.

Background & Objective: In this study, thyroid dysfunction in women with gestational diabetes mellitus was examined and compared to that in healthy pregnant women referred to Kowsar Hospital in Qazvin in 2017 and 2018.Methods: In this case-control study, 100 women with gestational diabetes mellitus and 100 non diabetic healthy pregnant women who referred to Kowsar Hospital in Qazvin from 2017 to 2018 were selected using the convenience sampling method, and their serum thyroxine, anti-TPO, and TSH levels were determined and compared. Moreover, Apgar scores and anthropometric variables were compared between the two groups.Results: In the present study, there were statistically significant differences between the groups in terms of the TSH level (P < /em>=0.012), assessed by the independent t-test, the thyroxine (P < /em>=0.0001) and anti-TPO (P < /em>=0.008) levels, both examined by the Mann-Whitney test, which associated with high levels of TSH and anti-TPO and low levels of thyroxine in the diabetic group. No differences were found regarding the Apgar scores and anthropometric variables between the groups (P < /em>>0.05).Conclusion: Overall, according to the obtained results, it can be inferred that thyroid dysfunction, realized as hypothyroid with high anti-TPO levels, was more prevalent in women with gestational diabetes mellitus compared to healthy pregnant women.
