Meta-Analysis Review
OBJECTIVE
Counseling of pregnancies complicated by pre- and periviable premature rupture of membranes to reach shared decision-making is challenging, and the current limited evidence hampers the robustness of the information provided. This study aimed to elucidate the rate of obstetrical and neonatal outcomes after expectant management for premature rupture of membranes occurring before or at the limit of viability.
DATA SOURCES
Medline, Embase, CINAHL, and Web of Science databases were searched electronically up to September 2023.
STUDY ELIGIBILITY CRITERIA
Our study included both prospective and retrospective studies of singleton pregnancies with premature rupture of membranes before and at the limit of viability (ie, occurring between 14 0/7 and 24 6/7 weeks of gestation).
METHODS
Quality assessment of the included studies was performed using the Newcastle-Ottawa Scale for cohort studies. Moreover, our study used meta-analyses of proportions to combine data and reported pooled proportions. Given the clinical heterogeneity, a random-effects model was used to compute the pooled data analyses. This study was registered with the International Prospective Register of Systematic Reviews database (registration number: CRD42022368029).
RESULTS
The pooled proportion of termination of pregnancy was 32.3%. After the exclusion of cases of termination of pregnancy, the rate of spontaneous miscarriage or fetal demise was 20.1%, whereas the rate of live birth was 65.9%. The mean gestational age at delivery among the live-born cases was 27.3 weeks, and the mean latency between premature rupture of membranes and delivery was 39.4 days. The pooled proportion of cesarean deliveries was 47.9% of the live-born cases. Oligohydramnios occurred in 47.1% of cases. Chorioamnionitis occurred in 33.4% of cases, endometritis in 7.0%, placental abruption in 9.2%, and postpartum hemorrhage in 5.3%. Hysterectomy was necessary in 1.2% of cases. Maternal sepsis occurred in 1.5% of cases, whereas no maternal death was reported in the included studies. When focusing on neonatal outcomes, the mean birthweight was 1022.8 g in live-born cases. The neonatal intensive care unit admission rate was 86.3%, respiratory distress syndrome was diagnosed in 66.5% of cases, pulmonary hypoplasia or dysplasia was diagnosed in 24.0% of cases, and persistent pulmonary hypertension was diagnosed in 40.9% of cases. Of the surviving neonates, the other neonatal complications included necrotizing enterocolitis in 11.1%, retinopathy of prematurity in 27.1%, and intraventricular hemorrhage in 17.5%. Neonatal sepsis occurred in 30.2% of cases, and the overall neonatal mortality was 23.9%. The long-term follow-up at 2 to 4 years was normal in 74.1% of the available cases.
CONCLUSION
Premature rupture of membranes before or at the limit of viability was associated with a great burden of both obstetrical and neonatal complications, with an impaired long-term follow-up at 2 to 4 years in almost 30% of cases, representing a clinical challenge for both counseling and management. Our data are useful when initially approaching such patients to offer the most comprehensive possible scenario on short- and long-term outcomes of this condition and to help parents in shared decision-making.

BACKGROUND
Congenital lower urinary tract obstruction (LUTO) is a rare but significant condition affecting fetal urinary tract development. LUTO has a range of etiologies, with posterior urethral valves (PUV) being the most common cause. The prenatal diagnosis of LUTO plays a crucial role in recognizing the condition and guiding management decisions. Prenatal ultrasound serves as the primary tool for identifying LUTO, with key findings including megacystis, bladder wall thickening, oligohydramnios, hydronephrosis, and the 'keyhole sign' indicating dilatation of the posterior urethra. We present a case of congenital LUTO with a rare complication of spontaneous fetal bladder rupture and urinary ascites, treated by peritoneo-amniotic shunt placement.
CASE PRESENTATION
A 27-year-old pregnant Caucasian women was referred at 28 weeks of pregnancy due to the presence of megacystis and bilateral hydronephrosis on routine ultrasound and suspicion of LUTO. Repeat ultrasound at 29 weeks showed significant fetal ascites, oligohydramnios and resolution of megacystis and hydronephrosis, after which diagnosis of spontaneous bladder rupture was made. Despite ascites aspiration and amnio-infusion, there was persistent ascites and oligohydramnios. A peritoneo-amniotic shunt was placed with resolution of ascites and normalization of the amniotic fluid volume. At 35 weeks, relapse of the megacystis was observed with bilateral pyelectasis and oligohydramnios, possibly due to healing of the bladder rupture, after which elective cesarean section was planned. Cystography confirmed spontaneous healing of the bladder rupture and the presence of posterior urethral valves, which were resected in the neonatal period with cold knife incision. Total follow-up of 8 years continued to show positive ultrasonographic results and good renal function, but the child suffers from bladder dysfunction, manifesting as overactive bladder disease.
CONCLUSIONS
LUTO might lead to important renal dysfunction and pulmonary hypoplasia in case of increasing disease severity. Spontaneous bladder rupture might improve renal prognosis, acting as a pop-off mechanism by decompression of the urinary tract. However, fetal bladder rupture is rare and only few cases have been reported. Prenatal intervention can be considered for moderate or severe LUTO, but the benefit for long-term outcome remains uncertain and further studies are needed.

BACKGROUND
Birth weight has a significant impact on perinatal mortality. Therefore, the estimation of fetal weight greatly influences the policies necessary for care during and after delivery. We aimed to investigate Johnson's rule in estimating fetal weight.
MATERIALS AND METHOD
This study was a single-group longitudinal study that was conducted in 6 months from October 2021 to April 2022 on 150 pregnant women in Isfahan-Iran. The sampling method was accessible. Inclusion criteria include being term, singleton, without abnormality, intact membranes, cephalic presentation, and exclusion criteria include diagnosed polyhydramnios or oligohydramnios and mother's abdominal or pelvic known masses. After completing the informed consent, fetal weight was estimated by Johnson's rule and was compared with the birth weight. Descriptive and analytical statistics (mean-standard deviation (SD), number-percentage, t-paired, and Spearman's correlation coefficient) were used to achieve the objectives of the study. The receiver operating characteristic (ROC) curve was also used to determine the sensitivity, specificity, and positive and negative predictive value of Johnson's law.
RESULT
The mean (SD) birth weight was 3032.88 ± 481.11 g and the mean (SD) estimated fetal weight (EFW) by the clinical method was 3152.15 ± 391.95 g. There was a significant difference between the averages ( < 0.001). The percentage error of EFW showed a significant negative correlation (r = -0.286; < 0.05) with gestational age (GA) and a significant positive correlation (r = 0.263; < 0.05) with the fetal head station. The sensitivity and specificity of EFW with Johnson's rule, in normal fetal birth weight, were higher than in low birth weight fetal. The accuracy of EFW with ± 10% of the actual weight was higher in average for gestational age (AGA) (84.3%) and high-for-gestational-age (LGA) (70%) than in low-for-gestational-age (SGA) (4%). The EFW mean percentage error in SGA was higher than in the other two weight groups. This method, especially for AGA and LGA fetuses, can be a suitable alternative to other weight estimation methods.
CONCLUSION
Clinical estimation of weight via Johnson's rule due to availability and no cost can be a suitable method for managing childbirth based on fetal weight.

Research on fetal loss related to germline mutations in single genes remains limited. Disruption of has recently been established in association with perinatal deaths characterized by hydranencephaly, renal dysplasia, oligohydramnios, and characteristic dysmorphisms. We herein present a Chinese family with recurrent fetal losses due to compound heterozygous nonsense variants. The Chinese couple had a history of five pregnancies, with four of them proceeding abnormally. Two stillbirths (II:3 and II:4) sequentially occurred in the third and fourth pregnancy. Prenatal ultrasound scans revealed phenotypic similarities between fetuses II:3 and II:4, including oligohydramnios, bilateral renal dysplasia and hydrocephalus/hydranencephaly. Clubfoot and syndactyly were also present in both stillborn babies. Fetus II:3 presented with endocardial cushion defects while fetus II:4 did not. With the product of conception in the fourth pregnancy, whole exome sequencing (WES) on fetus II:4 identified compound heterozygous nonsense variants comprised of c.190C>T(p.Arg64*) and c.208A>T(p.Lys70*). Both variants were expected to result in lack of the TSG101 and ALIX binding domain. Sanger sequencing confirmed the presence and cosegregation of both variants. This is the fifth reported family wherein biallelic variants lead to multiple perinatal deaths. Our findings, taken together with previously described phenotypically similar cases and even those with a milder and viable phenotype, broaden the genotypic and phenotypic spectrum of -associated lethal fetal syndrome, highlighting the vital biomolecular function of CEP55.

BACKGROUND
Renal oligohydramnios (ROH) describes an abnormally low volume of amniotic fluid (AF) during pregnancy. ROH is mostly caused by congenital fetal kidney anomalies. The ROH diagnosis frequently implies an increased risk of peri- and postnatal fetal mortality and morbidity. The present study aimed to evaluate the impact of ROH on pre-and postnatal development in children with congenital kidney anomalies.
METHODS
This retrospective study included 168 fetuses with anomalies in the kidney and urinary tract. Based on the amount of AF measured by ultrasound, patients were divided into three groups: normal amniotic fluid (NAF), amniotic fluid in the lower normal range (LAF), and ROH. These groups were compared with respect to prenatal sonographic parameters, perinatal outcomes, and postnatal outcomes.
RESULTS
Among the 168 patients with congenital kidney anomalies, 26 (15%) had ROH, 132 (79%) had NAF, and 10 (6%) had LAF. Of the 26 families affected by ROH, 14 (54%) decided to terminate pregnancy. Of 10 live-born children in the ROH group, 6 (60%) survived the observation time; of these, 5/6 presented with chronic kidney disease, stages I-III, at their last examination. The main differences in postnatal development between the ROH group and the NAF and LAF groups were: restricted height and weight gain, respiratory issues, complicated feeding, and the presence of extrarenal malformations.
CONCLUSIONS
ROH is not a mandatory indicator of severe postnatal kidney function impairment. However, children with ROH have complicated peri-and postnatal periods, due to the presence of concomitant malformations, which must be considered in prenatal care.

BACKGROUND
Fetal ultrasound has limitations, especially if the patient is obese or in cases with oligohydramnios. Magnetic resonance imaging (MRI) can then be used as a complement, but only few studies have focused on examinations in the second trimester.
PURPOSE
To validate MRI as a complement to diagnose fetal anomalies in the second trimester.
MATERIAL AND METHODS
This retrospective study retrieved data from January 2008 to July 2012 from the Fetal Medicine Unit and Department of Radiology at Uppsala University Hospital. Ultrasound and MRI findings were reviewed in 121 fetuses in relation to the final diagnosis, including postpartum follow-up and autopsy results.
RESULTS
Of the 121 fetuses, 51 (42%) had a CNS anomaly and 70 (58%) a non-CNS anomaly diagnosed or suspected. MRI provided additional information in 21% of all cases without changing the management and revealed information that changed the management of the pregnancy in 13%. When a CNS anomaly was detected or suspected, the MRI provided additional information in 22% and changed the management in 10%. The corresponding figures for non-CNS cases were 21% and 16%, respectively. The proportion of cases with additional information that changed the management was especially high in patients with a BMI >30 kg/m (25%) and in patients with oligohydramnios (38%). In five cases in category III, false-positive ultrasound findings were identified.
CONCLUSIONS
MRI in the second trimester complements ultrasound and improves diagnosis of fetal CNS- and non-CNS anomalies especially when oligohydramnios or maternal obesity is present.

Background Pre-eclampsia is a multisystem progressive disorder associated with significant maternal and neonatal morbidity and mortality. It is essential to identify the potential indicators of associated complications in pre-eclampsia to improve pregnancy outcomes. Serum uric acid (UA) levels are increased in pregnancies complicated by pre-eclampsia. This study was performed to validate salivary UA as an alternative non-invasive biomarker to serum UA in pre-eclampsia. Methodology A total of 150 pregnant women were enrolled in the study. They were divided equally into three groups with 50 participants in each group. Group 1 included healthy normotensive pregnant women as control, group 2 included participants with non-severe pre-eclampsia and group 3 included participants with severe pre-eclampsia. Both salivary and serum UA were estimated in all the study participants and comparative analyses were done. Results Serum UA was elevated in 33(66%) and 48(96%) of participants in groups 2 and 3 respectively while saliva uric acid in 30(60%) and 43(86%) as compared with healthy controls who had serum UA raised in 14(28%) and salivary UA in 12(24%) with a significant p-value of 0.0001. The mean values of serum and salivary UA in group 1 were 4.5 ±1.16 mg/dl and 4.11±1.74 mg/dl respectively whereas in group 2 these were 6.12±1.86mg/dl and 5.96±1.90mg/dl and in group 3 these were 8.24±2.31mg/dl and 8.17±3.31mg/dl respectively. There was a significant correlation between serum and salivary UA values in groups 1 and 2, groups 1 and 3, and groups 2 and 3 with a p-value of 0. 001. The serum and salivary UA levels showed an increasing trend from healthy controls (group 1) to non-severe pre-eclampsia (group 2) with the highest values in severe pre-eclampsia (group 3). Oligohydramnios was present in 10(20%) cases in group 1 whereas 24(48%) cases in group 3. The appearance, pulse, grimace, activity, respiration (APGAR) score at 1 and 5 minutes was abnormal in 5(1.23%) and 7(1.33%) cases in group 1, 6(1.26%) and 7(1.29%) cases in group 2 and 5(1.73%) and 6(1.53%) cases in group 3. The area under curve (AUC) in group 2 was 0.778 for serum UA and 0.779 for salivary UA. In group 3, the AUC for serum UA values was 0.938 and for salivary UA 0.882. A statistically significant correlation between serum and salivary UA values in group 2 (non-severe pre-eclampsia) was found with a p-value of 0.001 and Pearson's correlation coefficient r of 0.738. Conclusions Serum and salivary UA levels correlate with the severity of pre-eclampsia with maximum levels in severe pre-eclampsia (group 3) followed by group 2 (non-severe pre-eclampsia) with the lowest levels in group 1 (healthy controls). The authors are of the opinion that a non-invasive salivary UA test can replace the serum UA test and can be a useful supplementation for conventional pre-eclampsia prediction.

OBJECTIVE
Insufficient thyroid hormone levels during pregnancy, especially in the first trimester, adversely affect maternal and fetal health. However, the impact of isolated hypothyroxinemia (IH) on adverse pregnancy outcomes remains controversial. Therefore, this study aimed to investigate the association between IH during the first trimester and adverse pregnancy outcomes.
METHODS
This prospective cohort study included 1236 pregnant women. Thyroid-stimulating hormone and free thyroxine levels were measured before 13 weeks of gestation. Logistic regression analysis and the Cochran-Armitage trend test were used to assess the association between IH in the first trimester and adverse pregnancy outcomes.
RESULTS
IH during the first trimester was associated with an increased risk of macrosomia. After adjusting for confounding factors, including age, body mass index, parity, abnormal pregnancy history, fasting blood glucose, and total cholesterol, multivariate logistic regression analysis showed that IH in the first trimester remained an independent risk factor for macrosomia. In addition, the risk of macrosomia increased with IH severity. However, no significant relationship was found between IH during the first trimester and gestational diabetes mellitus, hypertensive disorders of pregnancy, spontaneous abortion, premature rupture of membranes, placental abruption, oligohydramnios, premature delivery, fetal distress, or low birth weight.
CONCLUSION
IH during the first trimester did not increase the risk of adverse pregnancy outcomes, except for macrosomia.

BACKGROUND
COVID-19 is the leading cause of the recent pandemic in the globe. This disease might have different effects on the maternal and fetal outcomes in pregnancy. The aim of this study was to assess these outcomes in pregnant women with COVID-19 infections in different trimesters.
MATERIALS AND METHODS
This is a prospective cohort study that was performed in February 2020 to August 2021 in Isfahan on 430 pregnant women with definite diagnosis of COVID-19 infection admitted to our medical centers. The included cases were followed based on the gestational age in which they were diagnosed with COVID-19 infection. Patients were divided into three groups (first, second, and third trimesters) based on COVID-19 infection.
RESULTS
The frequency of requiring mechanical ventilation was higher in mothers with COVID-19 in the second trimester ( = 0.049) and the frequency of PIH was significantly higher in mothers with COVID-19 in the third trimester compared to other women ( = 0.009). Fetal growth restriction (FGR) was also observed in 22 patients (5.3%) that was mostly observed with COVID-19 in the third trimester ( = 0.012). Oligohydramnios and fetal distress leading to C/S were observed in 19 patients (4.6%) and 12 patients (2.9%), respectively. The majority of maternal mortality was among cases with COVID-19 infection in the third trimester (44.4%).
CONCLUSION
We observed higher maternal and fetal complications in women especially those in the third trimester. Our results were in line with the findings of previous studies. Women with COVID-19 infection in the third trimester had highest frequencies of preterm labor and FGR.

Meta-Analysis
BACKGROUND
Established associated factors for DDH include female sex, breech presentation, family history, congenital malformations, oligohydramnios, and maternal hyperthyroidism. However, evidence for environmental factors that may contribute to DDH is limited and inconsistent.
METHODS
A systematic review of medical literature was conducted to collect data on environmental factors, including latitude, longitude, average yearly precipitation, average yearly temperature, minimum monthly temperature, and maximum monthly temperature, from all institutions that published articles on DDH. Univariate linear regression analysis was used to examine the correlation between environmental factors and DDH incidence, while multiple regression analysis was conducted to identify significant associated factors for DDH incidence.
RESULTS
Data from a total of 93 unique manuscripts were analyzed, revealing a significant negative correlation between DDH incidence and temperature, including average yearly temperature (r = -0.27, p = 0.008), minimum monthly temperature (r = -0.28, p = 0.006), and maximum monthly temperature (r = -0.23, p = 0.029). Additionally, there was a significant positive correlation between DDH incidence and latitude (r = 0.27, p = 0.009), and a significant negative correlation between DDH incidence and average yearly precipitation (r = -0.29, p = 0.004). In the final multiple regression analysis, temperature, including average yearly temperature, minimum monthly temperature, and maximum monthly temperature, were identified as significant associated factors for DDH incidence.
CONCLUSION
The findings of this study suggest an association between cold weather and DDH incidence. Further research should explore the link between cold weather and DDH incidence, offering insights into potential interventions for cold climates.
