Meta-Analysis Review
OBJECTIVE
To analyze outcomes of singleton pregnancies with idiopathic polyhydramnios through a systematic review and meta-analysis.
METHODS
Electronic databases, including MEDLINE, OVID, EBSCO, Cochrane collection and Science Citation Index, were searched from 1946 to 2019. Gray literature and tables of contents of relevant journals were also screened. Prospective and retrospective studies with a control group were included. Two authors independently reviewed the abstracts retrieved from the literature search. Inclusion criteria were: studies documented in English, singleton pregnancy and idiopathic polyhydramnios determined by amniotic fluid volume assessment on ultrasound. Exclusion criteria were: maternal diabetes, fetal structural or chromosomal anomaly, alloimmunization and intrauterine fetal infection.
RESULTS
Twelve studies met the inclusion criteria, giving a total of 2392 patients with idiopathic polyhydramnios and 160 135 patients with normal amniotic fluid volume. Pregnancies complicated by idiopathic polyhydramnios were at a higher risk of neonatal death (odds ratio (OR), 8.68 (95% CI, 2.91-25.87)), intrauterine fetal demise (OR, 7.64 (95% CI, 2.50-23.38)), neonatal intensive care unit admission (OR, 1.94 (95% CI, 1.45-2.59)), 5-min Apgar score < 7 (OR, 2.21 (95% CI, 1.34-3.62)), macrosomia (OR, 2.93 (95% CI, 2.39-3.59)), malpresentation (OR, 2.73 (95% CI, 2.06-3.61)) and Cesarean delivery (OR, 2.31 (95% CI, 1.79-2.99)).
CONCLUSIONS
This study suggests that pregnancies complicated by idiopathic polyhydramnios are at increased risk of adverse outcome. Future investigations should aim to determine an amniotic fluid volume threshold above which antenatal fetal surveillance is appropriate in the management of these pregnancies. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

Review
Although gastroschisis is often diagnosed by prenatal ultrasound, there is still a gap in the literature about which prenatal ultrasound markers can predict complex gastroschisis. This systematic review and meta-analysis aimed to investigate the ultrasound markers that characterize complex gastroschisis. A systematic review of the literature was conducted according to the guidelines of PRISMA. The protocol was registered (PROSPERO ID CRD42020211685). Meta-analysis was displayed graphically on Forest plots, which estimate prevalence rates and risk ratios, with 95% confidence intervals, using STATA version 15.0. The combined prevalence of intestinal complications in fetuses with complex gastroschisis was 27.0%, with a higher prevalence of atresia (about 48%), followed by necrosis (about 25%). The prevalence of deaths in newborns with complex gastroschisis was 15.0%. The predictive ultrasound markers for complex gastroschisis were intraabdominal bowel dilatation (IABD) (RR 3.01, 95% CI 2.22 to 4.07; I = 15.7%), extra-abdominal bowel dilatation (EABD) (RR 1.55, 95% CI 1.01 to 2.39; I = 77.1%), and polyhydramnios (RR 3.81, 95% CI 2.09 to 6.95; I = 0.0%). This review identified that IABD, EABD, and polyhydramnios were considered predictive ultrasound markers for complex gastroschisis. However, evidence regarding gestational age at the time of diagnosis is needed.

Nutrition & Diabetes May 2024Vitamin D deficiency has been linked with several adverse maternal and fetal outcomes.
BACKGROUND
Vitamin D deficiency has been linked with several adverse maternal and fetal outcomes.
OBJECTIVE
To summarize systematic reviews and meta-analyses evaluating the effects of vitamin D deficiency and of vitamin D supplementation in pregnancy on maternal and offspring health-related outcomes.
METHODS
Prior to conducting this umbrella review, we registered the protocol in PROSPERO (CRD42022368003). We conducted searches in PubMed, Embase, and Cochrane Library for systematic reviews and meta-analyses on vitamin D in pregnancy, from database inception to October 2, 2023. All outcomes related to vitamin D in pregnancy obtained from the systematic reviews and meta-analyses were extracted.
DATA EXTRACTION
Two reviewers independently chose studies and collected information on health outcomes. The quality of the included articles' methodology was assessed using AMSTAR 2 (A Measurement Tool to Assess Systematic Reviews-2).
RESULTS
We identified 16 eligible systematic reviews and meta-analyses, which included 250,569 women. Our results demonstrated that vitamin D deficiency in pregnancy is associated with increased risk of preterm birth, small-for gestational age/low birth weight infants, recurrent miscarriage, bacterial vaginosis and gestational diabetes mellitus. Vitamin D supplementation in pregnancy increases birth weight, and reduces the risk of maternal pre-eclampsia, miscarriage, and vitamin D deficiency, fetal or neonatal mortality, as well as attention-deficit hyperactivity disorder, and autism spectrum disorder in childhood. In women with gestational diabetes mellitus, vitamin D supplementation in pregnancy can reduce the risk of maternal hyperbilirubinemia, polyhydramnios, macrosomia, fetal distress, and neonatal hospitalization.
CONCLUSION
Due to the association with adverse maternal and offspring health outcomes, we recommend the vitamin D status in pregnancy should be monitored, particularly in women at high risk of vitamin D deficiency. It is suggested that pregnant women take a dose of >400 IU/day of vitamin D supplementation during pregnancy to prevent certain adverse outcomes.

Polyhydramnios is an obstetrical condition defined as a pathological increase in the amniotic fluid and is associated with a high risk of maternal-fetal complications. Common causes of polyhydramnios include fetal anatomical and genetic abnormalities, gestational diabetes mellitus, and fetal viral infections. We present the case of a 30-year-old Caucasian woman with transient polyhydramnios associated with gestational diabetes mellitus and obstetric complications. The diagnosis was based on the ultrasound assessment of amniotic fluid volume during a common examination at 26 weeks. Two weeks prior, the patient had been diagnosed with gestational diabetes mellitus. After 4 days, the patient was examined, and the amniotic fluid index returned to normal values. At 38 weeks, the patient presented to the emergency room due to lack of fetal active movement. Ultrasound revealed polyhydramnios, the patient was admitted for severe fetal bradycardia, and fetal extraction through emergency cesarian section was performed. Six weeks after birth, the patient underwent an oral glucose tolerance test with normal values, confirming gestational diabetes mellitus. We performed a systematic review of the literature on polyhydramnios, from January 2016 to April 2022, to analyze all recent published cases and identify the most common etiological causes and important aspects related to maternal-fetal outcomes.

Review
OBJECTIVE
Congenital nasopharyngeal masses (CNMs) are rare. Presenting symptoms vary, and the differential diagnoses cover a wide spectrum of possibilities. As it is uncommon, most examples discussed in literature are described as case reports or series. Guidelines on CNM patient management do not exist. In this study, we present two (2) cases of neonates with CNMs that were encountered at our tertiary center. Additionally, to best elaborate a comprehensive, case-based approach to CNM management, we offer an up-to-date, diagnosis-to-treatment review of current literature.
METHODS
Case series and systematic literature review.
RESULTS
Twenty-eight (28) studies are included since January 2000 to October 2021, with a total of 41 cases. Most common diagnosis was teratoma (78%). Female-to-male ratio was 2.5:1. Twenty percent of cases presented prenatally with polyhydramnios or elevated alpha-fetoprotein. Postnatally, the presenting symptoms most frequently encountered were respiratory distress (78%), oral mass (52%), and feeding difficulties (29%). Seventy-five percent of affected newborns showed symptoms within the first 24 hours of life. Forty percent of cases had comorbidities, especially in the head and neck region.
CONCLUSIONS
Congenital nasopharyngeal masses can be detected antenatally, or symptomatically immediately after birth. Airway protection is a cornerstone in the management. Selecting the right imaging modality and convening a multidisciplinary team meeting are important toward the planning of next steps/therapeutic approach. Typically, a transnasal or transoral surgical approach will be deemed sufficient to address the problem, with a good overall prognosis.

Meta-Analysis
INTRODUCTION
The use of metformin for treating gestational diabetes mellitus (GDM) remains controversial because it can pass through the placenta. This meta-analysis aimed to compare the effects of metformin and insulin on maternal and neonatal outcomes in patients with GDM.
METHODS
We conducted a comprehensive search of the PubMed, Embase, and Cochrane Library databases, focusing on randomized controlled trials (RCTs) that evaluated the impacts of metformin and insulin on both maternal and neonatal outcomes in patients with GDM.
RESULTS
Twenty-four RCTs involving 4934 patients with GDM were included in this meta-analysis. Compared with insulin, metformin demonstrated a significant reduction in the risks of preeclampsia (RR 0.61, 95% CI 0.48 to 0.78, < .0001), induction of labor (RR 0.90, 95% CI 0.82 to 0.98, = .02), cesarean delivery (RR 0.91, 95% CI 0.85 to 0.98, = .01), macrosomia (RR 0.67, 95% CI 0.53 to 0.83, = .0004), neonatal intensive care unit (NICU) admission (RR 0.75, 95% CI 0.66 to 0.86, < .0001), neonatal hypoglycemia (RR 0.55, 95% CI 0.48 to 0.63, < .00001), and large for gestational age (LGA) (RR 0.80, 95% CI 0.68 to 0.94, = .007). Conversely, metformin showed no significant impact on gestational hypertension (RR 0.84, 95% CI 0.67 to 1.06, = .15), spontaneous vaginal delivery (RR 1.13, 95% CI 1.00 to 1.08, = .05), emergency cesarean section (RR 0.94, 95% CI 0.77 to 1.16, = .58), shoulder dystocia (RR 0.65, 95% CI 0.31 to 1.39, = .27), premature birth (RR 0. 92, 95% CI 0.61 to 1.39, = .69), polyhydramnios (RR 1.11, 95% CI 0.54 to 2.30, = .77), birth trauma (RR 0.87, 95% CI 0.54 to 1.39, = .56), 5-min Apgar score < 7 (RR 1.13, 95% CI 0.76 to 1.68, = .55), small for gestational age (SGA) (RR 0.93, 95% CI 0.71 to 1.22, = .62), respiratory distress syndrome (RDS) (RR 0.74, 95% CI 0.50 to 1.08, = .11), jaundice (RR 1.09, 95% CI 0.95 to 1.25, = .24) or birth defects (RR 0.80, 95% CI 0.37 to 1.74, = .57).
CONCLUSIONS
The findings suggest that metformin can reduce the risk of certain maternal and neonatal outcomes compared with insulin therapy for GDM. However, long-term follow-up studies of patients with GDM taking metformin and their offspring are warranted to provide further evidence.

Meta-Analysis
Effectiveness of telemedicine for pregnant women with gestational diabetes mellitus: an updated meta-analysis of 32 randomized controlled trials with trial sequential analysis.
BACKGROUND
Gestational diabetes mellitus (GDM) is now a global health problem. Poor blood glucose control during pregnancy may lead to maternal and neonatal/foetal complications. Recently, the development of information and communication technology has resulted in new technical support for the clinical care of GDM. Telemedicine is defined as health services and medical activities provided by healthcare professionals through remote communication technologies. This study aimed to update the systematic review of the effectiveness of telemedicine interventions on glycaemic control and pregnancy outcomes in pregnant women with GDM.
METHODS
We searched the Web of Science, PubMed, Scopus, Cochrane Central Register of Controlled Trials, Chinese National Knowledge Infrastructure, Wan-fang Database, China Biology Medicine and VIP Database for randomized controlled trials (RCTs) related to the effectiveness of telemedicine interventions for GDM from database inception to July 31st, 2019. Languages were limited to English and Chinese. Literature screening, data extraction and assessment of the risk of bias were completed independently by two reviewers. Meta-analysis and trial sequential analysis were conducted in Stata 14.0 and TSA v0.9.5.10 beta, respectively.
RESULTS
A total of 32 RCTs were identified, with a total of 5108 patients. The meta-analysis showed that telemedicine group had significant improvements in controlling glycated haemoglobin (HbA1c) [mean difference (MD) = - 0.70, P < 0.01], fasting blood glucose (FBG) (MD = -0.52, P < 0.01) and 2-h postprandial blood glucose (2hBG) (MD = -1.03, P = 0.01) compared to the corresponding parameters in the standard care group. In the telemedicine group, lower incidences of caesarean section [relative risk (RR) = 0.82, P = 0.02], neonatal hypoglycaemia (RR = 0.67, P < 0.01), premature rupture of membranes (RR = 0.61, P < 0.01), macrosomia (RR = 0.49, P < 0.01), pregnancy-induced hypertension or preeclampsia (RR = 0.48, P < 0.01), preterm birth (RR = 0.27, P < 0.01), neonatal asphyxia (RR = 0.17, P < 0.01), and polyhydramnios (RR = 0.16, P < 0.01) were found. The trial sequential analyses conclusively demonstrated that the meta-analytic results of the change in HbA1c, the change in 2hBG, the change in FBG, the incidence rates of caesarean section, pregnancy-induced hypertension or preeclampsia, premature rupture of membranes, premature birth, neonatal asphyxia, and polyhydramnios were stable.
CONCLUSIONS
Compared to standard care, telemedicine interventions can decrease the glycaemic levels of patients with GDM more effectively and reduce the risk of maternal and neonatal/foetal complications.

Review
This study aims to evaluate the outcomes of fetal sacrococcygeal teratoma (SCT) submitted to prenatal interventions. We performed a systematic literature review of fetal SCT patients and compared the outcomes between open fetal surgery and percutaneous intervention. In addition, we also compared the results of SCT fetuses who did not undergo any surgical intervention (NI). We identified 16 cases of open fetal surgery (OS), 48 cases of percutaneous fetal intervention (PI), and 93 NI patients. The survival rate was 56.2% in OS, 45.8% in PI ( = 0.568), and 71.0% in NI patients. The gestational age at delivery was earlier in cases where there was no survival compared to cases where the fetuses did survive across all evaluated cohorts (OS: = 0.033, PI: < 0.001, NI: < 0.001). The gestational weeks at delivery in OS and PI fetuses were more similar; however, OS tended to be performed later on in pregnancy, and the affected fetuses had more severe presented findings. In our evaluation, we determined that the presence of fetal hydrops and cardiac failure had no significant impact on survival in SCT cases. In NI patients, polyhydramnios was much higher in fetuses who did not survive compared to their surviving cohorts ( < 0.001). In conclusion, gestational age at delivery can affect the short-term prognosis of fetuses affected with sacrococcygeal teratomas. Regardless of the mode of delivery or the necessity for intervention during the fetal period, monitoring for complications, including polyhydramnios, can prevent premature delivery.

Meta-Analysis
Although the assessment of the amniotic fluid volume in pregnancy is part of the fetal wellbeing surveillance, the impact of idiopathic polyhydramnios (IP) on maternal and perinatal outcomes in unknown. The aim of this meta-analysis was to investigate the association of IP with different maternal and perinatal outcomes. We screened five electronic databases until December 2023 and performed data extraction and quality assessment using ROBINS-E in duplicates. Pooled risk ratios and 95% confidence intervals (95% CI) were calculated with a random effects model. 38 studies were included. Patients with IP were at increased risk of perinatal complications including preterm delivery (RR 1.96, 95% CI 1.35-2.86; I = 92%), placental abruption (RR 3.20, 95% CI 2.20-4.65; I = 2%), delivery via caesarean section (RR 1.60, 95% CI 1.39-1.84; I = 95%) and postpartum haemorrhage (RR 1.98, 95% CI 1.22-3.22; I = 84%). Similarly, IP was associated with increased risk of adverse perinatal outcomes including low APGAR score (RR 3.0, 95% CI 1.23-7.35; I = 95%), stillbirth (RR 4.75, 95% CI 2.54-8.86; I = 9%) and perinatal mortality (RR 4.75, 95% CI 2.67-8.48; I = 37%). This meta-analysis suggests that pregnant women with IP may be at increased risk of perinatal complications and adverse neonatal outcomes. However, data remains inconclusive considering the low quality and high heterogeneity of included studies.PROSPERO registration number: CRD42022359944.

Lethal congenital contracture syndrome type 7 (LCCS7) and congenital hypomyelinating neuropathy type 3 (CHN3) are rare autosomal recessive diseases, characterized by severe neonatal hypotonia, polyhydramnios, arthrogryposis, facial diplegia, and severe motor paralysis, leading to death in early infancy. They are related to mutations in the (contactin associated protein 1) gene, playing an important role in myelination. Recent studies have shown that both diseases could present with a wide phenotypic spectrum, with promising survival up to early childhood. We report on a 7-year-old boy from a nonconsanguineous Lebanese family presenting with neonatal hypotonia, respiratory distress, and arthrogryposis. Molecular analysis revealed the presence of a pathogenic variant in the gene leading to a premature stop codon: NM_003632.2:c.3361C>T p.(Arg1121 ). A review of the literature is discussed.
