RESUMEN
BACKGROUND: Penile duplication or diphallia is a rare congenital anomaly with unclear pathophysiological cause. Most cases of diphallia are reported postnatally; however, today with the use of a high-resolution ultrasound device, in-uterine diagnosis of many congenital anomalies is possible. CASE PRESENTATION: Herein we report a multiparous mother at 25 weeks of gestation who referred due to an abnormal cystic structure protruding from a large abdominal wall defect located below the umbilicus that was noted during a routine exam. Target scan revealed two penile-like protrusions with an empty scrotal sac and double bladder in an otherwise normal fetus, which was confirmed postnatally. Neonatal microarray study and karyotype were normal. CONCLUSION: Diphallia could be detected prenatally as an isolated anomaly, associated with caudal duplication syndrome, or as an exstrophy-epispadias complex. As this is a rare congenital anomaly, all sonographers should be familiar with prenatal ultrasound features and associated anomalies, an important issue in prenatal counseling with parents, delivery planning, psychological support of the family, and postnatal management.

OBJECTIVES: Preterm birth (PTB) is the common cause of neonatal mortality nationwide. The present study aimed to evaluate the efficacy of different doses of aspirin in preventing PTB in high-risk pregnant women. As secondary outcomes, other perinatal complications were compared. METHODS: This double-blind randomized clinical trial was conducted on high-risk pregnant women with impaired placental perfusion diagnosed in the first trimester of pregnancy referring to the perinatal centers affiliated to Shiraz university of Medical Sciences between February 2020 and March 2021. The subjects were randomly divided in two groups administered with 150 or 80 mg aspirin every night from 11 to 13+6 weeks until 36 weeks or delivery. This study is registered in the Iranian Registry of Clinical Trials (IRCT20140317017035N6; http://www.irct.ir/). Univariate and multiple logistic regressions were applied using SPSS 22. RESULTS: A total of 101 subjects received 80 mg aspirin and 89 ones received 150 mg aspirin. The results of multiple analysis revealed a significantly lower odds of PTB (OR 0.4 (0.19, 0.99)) in the 150 mg group compared to the 80 mg group. As secondary outcomes, preeclampsia (PEC) and PEC with severe features (PECsf) were lower (OR 0.2 (0.06, 0.82) and 0.1 (0.01, 0.92), respectively); however, fetal age and neonatal weight were higher in the 150 mg group (OR 1.2 (1.04, 1.33) and 1.001 (1-1.001), respectively). CONCLUSIONS: The study findings indicated that, compared with 80 mg of aspirin, taking 150 mg of aspirin reduced PTB and perinatal complications in high risk pregnant women.

AIM: To compare the success rate of vaginal misoprostol versus intravenous (IV) oxytocin in termination of pregnancy in the second trimester intrauterine fetal death (IUFD). METHODS: This was an open-label randomized controlled study for 106 women with second trimester IUFD. Patients were randomly divided into two groups: women given vaginal misoprostol (400 mcg every 6 h up to 48 h) versus those given IV oxytocin (starting with 50 units up to a maximum of 300 units). When the first-line treatment (as mentioned above) failed, treatment methods were replaced with each other. When the second-line treatment failed, the patients underwent dilation and evacuation. RESULTS: The first-line treatment yielded the successful rate of 88.7% versus 73.7% for misoprostol versus oxytocin, respectively (p = 0.047). Among those with first-line treatment failure, the second-line treatment yielded success rate of 85.7% versus 83.3% for misoprostol versus oxytocin (p = 0.891). The mean duration of induction to delivery in women with successful response to first-line treatment was 28.72 and 20.55 h after initially receiving misoprostol versus oxytocin, respectively (p < 0.001). While during second-line treatment, this mean interval was not significantly different among those with misoprostol versus oxytocin (p = 0.128). No severe adverse events were observed. CONCLUSION: Vaginal misoprostol was associated with higher termination rate than oxytocin without adverse events when used as the first-line treatment. Both methods yielded the same success rate when used as the second-line treatment.

This study aimed to assess the maternal features, Vascular Endothelial Growth Factor (VEGF) and Placenta Growth Factor (PLGF) in the Placenta Accreta Spectrum (PAS); then, to determine a predictive value of VEGF and PLGF in the PAS. This prospective case-control study was conducted on 90 pregnant women including 45 PAS, and 45 Normal Placenta (NP). Maternal age, gravidity, C/S, and serum levels of VEGF and PLGF were assessed between NP and PAS, and among NP and PAS sub-groups, including Placenta Accreta (PA), Placenta Increta (PI), and Placenta Percreta (PP). The Multi-gravidity, previous C/S, maternal age, and serum level of PLGF were significantly higher in the PAS group compared to the NP group OR = 42, 8.1, 1.17, and 1.002 (p-value <.05 for all); however, there was no difference regarding serum level of VEGF (p-value >.05). The same differences were seen among NP with PA, PI, and PP sub-groups (p-value <.05 for all, but p-value >.05 for VEGF). Placenta Previa was uniformly distributed across the PAS sub-groups (p-value >.05), also the VEGF and PLGF serum levels did not differ between PAS with Previa and PAS without Previa groups (p-value >.05). A valid cut-off point for PLGF was reported at 63.55. A predictive value of PLGF for the PAS patients is presented enjoying high accuracy and generalisability for the study population.Impact statementWhat is already known on this subject? The Placenta Accreta Spectrum (PAS), in which the placenta grows too deep in the uterine wall, is responsible for maternal-foetal morbidity and mortality worldwide; so, the antenatal diagnosis of PAS is an important key to improve maternal-foetal health. Normal placental implantation requires a fine balance among the levels of angiogenic and anti-angiogenic factors, such as the Placenta Growth Factor (PLGF), the Vascular Endothelial Growth Factor (VEGF), and soluble Fms-like tyrosine kinase-1. However, there is still controversy regarding The PLGF and VEGF level changes in PAS patients.What do the results of this study add? Despite traditional measuring the levels of PLGF and VEGF from the placenta at the time of delivery; in this study including 90 participants (28-34 weeks of gestation) the maternal serum levels of PLGF and VEGF were measured in advance (temporality causation), resulted in presenting a more valid cut-off point for PLGF in PAS group. In addition, the serum level of PLGF was significantly higher in the PAS and PAS sub-groups compared to the Normal Placenta group. Also, the Previa status of PAS patients did not affect the VEGF and PLGF serum levels.What are the implications of these findings for clinical practice and/or further research? PLGF cut-off point derived from the maternal serum level could predict PAS validly and, if used as a screening test in an earlier pregnancy, the maternal-foetal morbidity and mortality would decrease.

BACKGROUND: Interstitial Pregnancy (IP) is a lethal condition due to high risk of sudden onset massive hemorrhage. Such conditions are managed as soon as diagnosed almost in the first trimester. There are a few case reports of IP conditions terminated after the second trimester. Herein, we introduce a term interstitial pregnancy complicated by abnormal placentation. CASE PRESENTATION: In this case report, we introduce a 32-year-old lady, primigravida, with an undiagnosed IP that was in her 38 weeks of gestational with placenta increta. She developed with perforated IP presenting with acute abdomen and internal bleeding at 26 weeks of gestational age. However, with a misdiagnosis impression, she got stable in operation room. Then, the pregnancy continued till 36 weeks of gestational age that was misdiagnosed with cervical cancer in prenatal work-ups. Finally, during elective cesarean section at 38 weeks, an IP with placenta increta (placenta evading from the serosa to the myometrium of the uterus) was observed. The baby was healthy with no obvious anomaly or morbidity. CONCLUSIONS: Physicians should be aware to detect IP in all trimesters and pay attention to the coexisting complications such as placenta accreta to manage them more accurately.

BACKGROUND: Chorangiosis is a vascular change involving the terminal chorionic villi in the placenta. It results from longstanding, low-grade hypoxia in the placental tissue, and is associated with such conditions as intrauterine growth restriction (IUGR), diabetes, and gestational hypertension in pregnancy. Chorangiosis rarely occurs in normal pregnancies. However, its prevalence is 5-7% of all placentas from infants admitted to newborn intensive care units. The present study was aimed at determining the association of chorangiosis with pregnancy complications and perinatal outcomes. METHODS: In this case-control study, 308 chorangiosis cases were compared with 308 controls (with other diagnoses in pathology) in terms of maternal, placental, prenatal, and neonatal characteristics derived from the medical records of participants retrospectively. R and SPSS version 22 software tools were used, and the statistical significance level was considered 0.05 for all the tests. RESULTS: Preeclampsia, diabetes mellitus, maternal hemoglobin, maternal hematocrit, C/S, oligohydramnios, fetal anomaly, dead neonates, NICU admissions were significantly higher in the chorangiosis group OR = 1.6, 3.98, 1.68, 1.92, 2.1, 4.47, 4.22, 2.9, 2.46, respectively (p-value< 0.05 for all). Amniotic fluid index, birth weight, cord PH amount, 1st, and 5th Apgar score was lower in the chorangiosis group OR = 0.31, 1, 0.097, 0.83, 0.85, respectively (p-value< 0.05 for all). Moreover, fundal placenta, retro placental hemorrhage, perivillous fibrin deposition, calcification, and acute chorioamnionitis were higher in the chorangiosis group OR = 2.1, 11.8, 19.96, 4.05, and 6.38 respectively, (p-value< 0.05). There was a high agreement between the two pathologists, and the power of the study was estimated at 99%. CONCLUSION: Although chorangiosis is an uncommon condition, it is associated with a higher incidence of perinatal and neonatal morbidity and mortality. Therefore, it should be considered an important clinical sign of adverse pregnancy outcomes and should be reported in the pathology evaluation.

BACKGROUND: Prenatal corticosteroid administration is known to be an effective strategy in improving fetal pulmonary maturity. This study aimed to evaluate the impact of maternal betamethasone administration on fetal pulmonary and other arteries Doppler velocity and the correlation between RDS development and Doppler indices results. METHODS: Fifty one singleton pregnancies between 26 and 34 gestational weeks with a diagnosis of preterm labor were included in the exposed group and received betamethasone. Fifty one uncomplicated pregnancies were included in the non-exposed group. Fetal pulmonary, umbilical and middle cerebral arteries Doppler parameters were evaluated before and 24 to 48 h after steroid administration in the exposed group and two times at same intervals in the non-exposed group. Maternal records were matched to neonatal charts if delivery happened, and demographic and outcome data were abstracted. RESULTS: When compared with the nonexposed group, fetuses treated with corticosteroids demonstrated significantly decreased umbilical artery Pulsatility index (PI) and significantly increased the middle cerebral artery PI, pulmonary artery Acceleration time (AT) and pulmonary artery AT/ET (Ejection time), while all other indices remained similar. We found significantly decreased pulmonary artery AT in the fetuses with respiratory distress syndrome (RDS) compared to those that did not. CONCLUSIONS: The results of our study showed that maternal antenatal betamethasone administration caused significant changes in the fetus blood velocity waveforms and also affected the blood flow in the pulmonary artery which led to an increase in the pulmonary artery AT and AT/ET. Among those fetuses with RDS, we found a significant decrease in the pulmonary artery AT, but we did not observe any pulmonary artery AT/ET differences.

BACKGROUND: We aimed to investigate the risk factors of placenta accreta spectrum (PAS) disorder, management options and maternal and neonatal outcomes of these pregnancies in a resource-limited clinical setting. METHODS: All women diagnosed with placenta accreta, increta, and percreta who underwent peripartum hysterectomy using a multidisciplinary approach in a tertiary center in Shiraz, southern Iran between January 2015 until October 2019 were included in this retrospective cohort study. Maternal variables, such as estimated blood loss, transfusion requirements and ICU admission, as well as neonatal variables such as, Apgar score, NICU admission and birthweight, were among the primary outcomes of this study. RESULTS: A total number of 198 pregnancies underwent peripartum hysterectomy due to PAS during the study period, of whom163 pregnancies had antenatal diagnosis of PAS. The mean gestational age at the time of diagnosis was 26 weeks, the mean intra-operative blood loss was 2446 ml, and an average of 2 packs of red blood cells were transfused intra-operatively. Fifteen percent of women had surgical complications with bladder injuries being the most common complication. Furthermore, 113 neonates of PAS group were admitted to NICU due to prematurity of which 15 (7.6%) died in neonatal period. CONCLUSION: Our findings showed that PAS pregnancies managed in a resource-limited setting in Southern Iran have both maternal and neonatal outcomes comparable to those in developed countries, which is hypothesized to be due to high rate of antenatal diagnosis (86.3%) and multidisciplinary approach used for the management of pregnancies with PAS.

The alteration of the uterocervical angle (UCA) has been proposed to play an important role in spontaneous preterm birth (sPTB). The aim of this systematic review and meta-analysis was to evaluate the evidence on the UCA predictive role in sPTB. In this study, PubMed, Web of Science, Scopus, and Google scholar were systematically searched from inception up to June 2020. Inter-study heterogeneity was also assessed using Cochrane's Q test and the I2 statistic. Afterward, the random-effects model was used to pool the weighted mean differences (WMDs) and the corresponding 95% confidence intervals (CIs). Eleven articles that reported second-trimester UCA of 5,061 pregnancies were included in this study. Our meta-analysis results indicate that a wider UCA significantly increases the risk of sPTB in following cases: all pregnancies (WMD = 15.25, 95% CI: 11.78-18.72, p < 0.001; I2 = 75.9%, p < 0.001), singleton (WMD = 14.43, 95% CI: 8.79-20.06, p < 0.001; I2 = 82.4%, p < 0.001), and twin pregnancies (WMD = 15.14, 95% CI: 13.42-16.87, p < 0.001; I2 = 0.0%, p = 0.464). A wider ultrasound-measured UCA in the second trimester seems to be associated with the increased risk of sPTB in both singleton and twin pregnancies, which reinforces the clinical evidence that UCA has the potential to be used as a predictive marker of sPTB.
RESUMEN
BACKGROUND: For the first time, we aimed to introduce a model for prediction of placenta accreta spectrum (PAS), using existing sonography indices. METHODS: Women with a history of Cesarean sections were included. Participants were categorized "high risk" for PAS if the placenta was previa or low-lying. Sonography indices including abnormal placental lacuna, loss of clear zone, bladder wall interruption, myometrial thinning, placental bulging, exophytic mass, utero-vesical hypervascularity, subplacental hypervascularity, existence of bridging vessels, and lacunar flow, were registered. To investigate simultaneous effects of 15 variables on PAS, Minimax Concave Penalty (MCP) was used. RESULTS: Among 259 participants, 74 (28.5%) were high risk and 43 individuals had PASs. All sonography indices were higher among patient with PAS (p < 0.001) in the high risk group. Our model showed that utero-vesical hypervascularity, bladder interruption and new lacunae have significant contribution in PAS. Optimal cut off point was p = 0.51 in ROC analysis. Probability of PAS for women with lacunae was between 96 and 100% and probability of PAS for women without lacunae was between 0 to 7%, therefore accuracy of the proposed model was equal to 100%. CONCLUSIONS: Using the introduced model based on three factors of abnormal lacuna structures (grades 2 and 3), bladder wall interruption and utero-vesical vascularity, 100% of all cases of PASs are diagnosable. If supported by future studies our model eliminates the need for other imaging assessments for diagnosis of invasive placentation among high risk women with previous history of Cesarean sections.

Conjoined twins are derived from the division of a single fertilized ovum; a phenomenon accompanied with multiple congenital anomalies. Such twins are identical, of the same sex, and more likely to be female. Most twins die during the embryonic period, and only 18% survive longer than 24 hours. There are complex anomalies in thoraco-omphalopagus twins that makes them unlikely to live long enough to undergo separation. Treatment of this uncommon condition presents both surgical and anesthetic challenges. The management of rare anomalies is difficult even for skilled surgeons. Therefore, it is logical to use the knowledge gained from previous experiences. We herein present the first successful surgical separation of two pairs of thoraco-omphalopagus conjoined twins at the Pediatric Surgery Center of Namazi Hospital (Shiraz, Iran). In both cases, the neonates had separate hearts and common pericardium. Contrast-enhanced computed tomography of two sets of twins showed fusion of sternum, pericardium, diaphragm, and left lobe of liver. Critical steps of the surgical separation were identified and contingency plans were made for possible partial liver donation and cross-circulation between twins. The separation procedure and reconstruction of the abdominal wall were successfully performed. Both pairs of twins, now 6- and 8-year-old, are healthy and have normal growth and are under follow-up.
RESUMEN
OBJECTIVES: To determine serum biomarkers in detection of preeclampsia severity among pregnant women. METHODS: Among 450 pregnant women with various severity of preeclampsia, serum biomarkers ofaspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), hemoglobin (Hb), platelet count (PLT), uric acid, direct bilirubin, total bilirubin, creatinine, and alkaline phosphatase were compared using area under the Receiver operating characteristic (ROC) curve and Area Under the Curve (AUC). RESULTS: The mean age of women was 30.63±6.43 years and with mean gestational age of 34.69±3.97 weeks. The mean level of LDH, ALT, uric acid, and creatinine were significantly higher in the women with severe type of preeclampsia compared to those with mild type. LDH level had ROC and AUC of more than 0.80, with highest sensitivity, and moderatespecificityin comparison to other markers. CONCLUSION: Biomarkers such as ALT, uric acid, and LDH were shown to be prognostic in detection of theseverity of preeclampsia. LDH was demonstrated to significantly be a better prognostic test in detection of preeclampsia severity.
RESUMEN
BACKGROUND: This experimental study aims to investigate the impact of combinations of prenatal and postnatal food manipulation on body composition in rat offspring. METHODS: On day 12 of gestation, 100 timed pregnant rats were randomized into two nutritional groups: standard laboratory and 50% starved. Pups born to starved mothers were subdivided, based on birthweight (BiW), into fetal growth restricted (FGR) and non-FGR. Pups were born on day 21, cross-fostered, then left undisturbed lactating until the 26th postnatal day when they underwent dual-energy X-ray absorptiometry (DXA) examination. RESULTS: Prenatally control-fed animals had a significantly greater body weight at 26 d postnatally than the prenatally starved groups, irrespective of their postnatal diet (P < 0.001). Postnatal control diet was associated with significantly increased abdominal and total fat in non-FGR compared to FGR rats (P < 0.001). non-FGR/CONTROL rats showed higher values of abdominal fat than prenatally starved animals that were starved postnatally irrespective of their birth weight (P < 0.001). Postnatal control diet significantly increased total bone mineral content (BMC), head BMC, head area, abdominal BMC in non-FGR compared to FGR rats (P < 0.001). CONCLUSION: Interaction between prenatal and postnatal nutrition affects growth, abdominal adiposity, and bone accrual in Wistar rats' offspring at 26 d of life.

PURPOSE: To report the outcomes of laparoscopic metroplasty in bicornuate and didelphic uteri. METHODS: This observational study includes 26 women with double uterine cavities (22 bicornuate and 4 didelphic uteri) with history of recurrent pregnancy loss undergoing laparoscopic metroplasty, second-look laparoscopy and hysteroscopy between 2008 and 2013 in University and Private hospital (Shiraz, Iran). The feasibility of laparoscopic metroplasty, appropriateness of the uterine cavity upon second-look laparoscopy, pregnancy outcome and live birth rate (within at least 12 month follow-up) were evaluated. RESULT(S): All patients had a unified and acceptable uterine cavity in second-look operation. Minimal pelvic adhesions in eight cases and subseptum of uterus in seven patients were detected which were removed by laparoscopy and resectoscopy, respectively. Out of 14 patients who could be followed for one year for pregnancy occurrence 12 patients had conception. Out of them nine term pregnancies with normal pregnancy and delivery outcomes were reported. These women delivered nine live neonates through the cesarean section. Three patients had pregnancy loss (2 early pregnancy losses and one with preterm delivery). Two patients decided to postpone conception due to personal reasons. CONCLUSION(S): Laparoscopic metroplasty by developing single uterine cavity with a suitable volume and minimal adhesion formation can be a substitute for laparotomy technique. However, more long-term studies should be done on larger sample size to confirm its positive effects on the pregnancy outcomes.

Key Clinical Message: Giant chorioangiomas, despite being rare, pose significant fetal and maternal risks. Timely and individualized treatment plans are crucial to reduce morbidity and mortality when fetal compromise occurs. Additionally, successful conservative management relies on consistent ultrasound monitoring, Doppler flowmetry assessments, and amniotic fluid level measurements. Abstract: Chorioangiomas are benign placental tumors that manifest in approximately 1% of pregnancies. Giant chorioangiomas, characterized by tumors exceeding 4 cm, are exceptionally rare and pose substantial risks to maternal and fetal health. This case report details a patient with multiple giant chorioangiomas, emphasizing the rarity and consequential complications associated with these tumors. A 23-year-old woman, G3P2, at 28 weeks gestational age, was diagnosed with multiple large, well-defined placental masses with increased vascularity, indicative of giant placental chorioangiomas. Subsequent ultrasound revealed various fetal anomalies such as cleft palate and lip, as well as lung and heart abnormalities. At 34+5 weeks of gestation, an emergency cesarean section was performed due to preeclampsia. Subsequently, a female neonate was born with hydrops fetalis. Unfortunately, she passed away within the first hour of her life. Complications associated with chorioangiomas primarily arise from arteriovenous shunts, which potentially lead to compromised fetal perfusion and cardiac failure. Although small-sized chorioangiomas are often discovered incidentally, Doppler ultrasound and magnetic resonance imaging can reliably distinguish these tumors from other placental lesions. Additionally, management strategies tailored to gestational age and maternal-fetal symptoms typically necessitate a multidisciplinary approach. However, additional research is essential to understand the mechanisms of chorioangiomas and to develop comprehensive management guidelines.
RESUMEN
OBJECTIVE: Pregnancy is a unique challenge for the immune system. Any disturbance in the immune system in the first trimester could result in further pregnancy complications. In this regard, the current study aimed to investigate the association between serum levels of a group of cytokines in the first trimester of pregnancy with the onset of preeclampsia (PE) and fetal growth restriction (FGR). MATERIALS AND METHODS: Serum samples were collected from 550 pregnant women at their 11th - 13th weeks of pregnancy and followed up to delivery. Out of all cases, 15 women complicated with preeclampsia and 15 ones diagnosed with FGR were included in the study. The serum levels of IFN-γ, CCL2, IL-10, IL-35 and IL-27 were checked in the collected sera of mentioned patients and compared to 60 women with normal pregnancy outcomes. RESULTS: In the preeclampsia group, the mean level of IFN-γ was significantly higher (p < 0.001) while the CCL2 serum level was significantly lower (p < 0.003) as compared to control group. There was no significant difference between the preeclampsia group and controls regarding other cytokines. In the FGR group, the mean serum level of IFN-γ was significantly higher compared to the healthy pregnancy group (p < 0.001) but other cytokines showed no significant differences. In the FGR group, a significant positive correlation was found between IL-10 level and neonates' weight (p < 0.05). CONCLUSION: Based on the results of the present study, an elevated level of IFN-γ and a reduced level of CCL2 at the first trimester of pregnancy could lead to complications such as PE and/or FGR.

OBJECTIVE: Recently the use of free fetal deoxyribonucleic acid (DNA) in maternal plasma and serum has been applicable for noninvasive prenatal genetic diagnosis. In this study, we applied a new algorithmic base conventional polymerase chain reaction (PCR) genotyping method and also real-time PCR for detecting fetal X and Y-chromosome sequences in maternal plasma to determine fetal sex in pregnant women in their early gestational ages (5-13 weeks). Finally, we compared the efficiency of each method in sex determination. STUDY DESIGN: DNA was extracted from 106 pregnant women and their husbands' blood samples. Fetus mini-short tandem repeat (STR) genotyping was accomplished through amplification of 19 mini-STRs and 3 non-STR markers using conventional PCR followed by polyacrylamide gel electrophoresis analysis. Simultaneously, TaqMan real-time PCR was done with the use of DYS14-specific primers and probe. RESULTS: In conventional PCR method, 47 cases were diagnosed to be male and 49 to be female. In comparison, real-time PCR amplified DYS14 (Y-marker) sequences in 45 pregnant women plasma samples. Sensitivity and specificity were calculated to be 95.9% and 98% for conventional PCR and 91.8% and 100% for real-time PCR method, respectively. CONCLUSION: According to our study, the conventional PCR method was more sensitive than real-time PCR and it could be employed in future clinical diagnostics singly or in combination with real-time PCR.

OBJECTIVE: ß-thalassemia is a prevalent disease in Iran. The adverse effects of anemia on placental and neonatal outcomes have previously been shown. Women require additional iron during pregnancy and the anemia of women with ß-thalassemia may adversely affect the neonatal outcome and increase placental abnormalities. In this study, we compared the placental histology and neonatal outcomes among pregnant women with and without ß-thalassemia. MATERIAL AND METHODS: In this population-based cross-sectional study, 144 pregnant women with ß-thalassemia minor (case group) were compared to 142 women without ß-thalassemia (control group). Women with singleton pregnancies over 20 weeks of gestation without pregnancy complications, anemia, collagen vascular diseases, or other hemoglobinopathies, all referred to hospitals affiliated to Shiraz University of Medical Sciences from March 2014 to February 2016, were included and maternal and neonatal data were extracted from medical records. After child birth, the placenta was evaluated for macroscopic and microscopic changes. RESULTS: The frequency of LBW was significantly higher in the case group than that in the control group (19.7 vs. 9.7%, respectively) (p = .019). Six in the case group had gross abnormalities of placenta, while none in the control group (p = .03) and the case group had a higher frequency of chorangiosis, calcification, syncytial knot, and umbilical cord position (p < .05). CONCLUSION: As ß-thalassemia increases the chance of placental abnormalities, it is recommended to pay more attention to patients with ß-thalassemia, especially during pregnancy, to prevent placental and neonatal adverse outcomes.

BACKGROUND: The new SARS-CoV-2 originated from Wuhan, China is spreading rapidly worldwide. A number of SARS-CoV-2 positive pregnant women have been reported. However, more information is still needed on the pregnancy outcome and the neonates regarding COVID-19 pneumonia. MATERIAL AND METHODS: A systematic search was done and nine articles on COVID-19 pneumonia and SARS-CoV-2 positive pregnant women were extracted. Some maternal-fetal characteristics were extracted to be included in the meta-analysis. RESULTS: The present meta-analysis was conducted on 87 SARS-CoV-2 positive pregnant women. Almost 65% of the patients reported a history of exposure to an infected person, 78% suffered from mild or moderate COVID-19, 99.9% had successful termination, 86% had cough, and 68% had fever (p = .022 and p < .001). The overall proportions of vertical transmission, still birth, and neonatal death were zero, 0.002, and, 0.002, respectively (p = 1, p = .86, and p = .89, respectively). The means of the first- and fifth-minute Apgar scores were 8.86 and 9, respectively (p < .001 for both). The confounding role of history of underlying diseases with an estimated overall proportion of 33% (p = .03) resulted in further investigations due to sample size limitation. A natural history of COVID-19 pneumonia in the adult population was presented, as well. CONCLUSION: Currently, no evidence of vertical transmission has been suggested at least in late pregnancy. No hazards have been detected for fetuses or neonates. Although pregnant women are at an immunosuppressive state due to the physiological changes during pregnancy, most patients suffered from mild or moderate COVID-19 pneumonia with no pregnancy loss, proposing a similar pattern of the clinical characteristics of COVID-19 pneumonia to that of other adult populations.
