MRI Assessed Placental Location as a Diagnostic Tool of Placental Invasiveness and Maternal Peripartum Morbidity. Diagnostics (Basel) 2024; 14:925. [PMID: 38732341 PMCID: PMC11083786 DOI: 10.3390/diagnostics14090925] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Revised: 04/16/2024] [Accepted: 04/24/2024] [Indexed: 05/13/2024] Open
Abstract
Placenta accreta spectrum (PAS) disorder is one of the leading causes of peripartum maternal morbidity and mortality; its early identification during pregnancy is of utmost importance to ensure the optimal clinical outcome. The aim of the present study is to investigate the possible association of the presence and type/location of placenta previa on MRI with PAS and maternal peripartum outcome. One hundred eighty-nine pregnant women (mean age: 35 years; mean gestational age: 32 weeks) at high risk for PAS underwent a dedicated placental MRI. All women underwent a C-section within 6 weeks from the MRI. All MRIs were evaluated by two experienced genitourinary radiologists for presence, type (complete/partial vs. marginal/low lying), and location (anterior vs. anterior-posterior vs. posterior) of placenta previa. Statistical analysis was performed for possible association of type/location of previa with placental invasiveness and peripartum outcomes. Intraoperative information was used as a reference standard. Complete/partial previa was detected in 143/189 (75.6%) and marginal/low lying previa in 33/189 (17.5%) women; in 88/189 (46.6%) women, the placenta had anterior-posterior, in 54/189 (28.6%) anterior and in 41/189 (21.7%) posterior. Complete/partial previa had an at least 3-fold probability of invasiveness and was more frequently associated with unfavorable peripartum events, including massive intraoperative blood loss or hysterectomy, compared to low-lying/marginal placenta. Posterior placental location was significantly associated with lower rates of PAS and better clinical outcomes. In conclusion, the type and location of placenta previa shown with MRI seems to be associated with severity of complications during delivery and should be carefully studied.

Visceral Leishmaniasis in a Twin Pregnancy: A Case Report and Review of the Literature. J Clin Med 2024; 13:2400. [PMID: 38673673 PMCID: PMC11051246 DOI: 10.3390/jcm13082400] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2024] [Revised: 04/10/2024] [Accepted: 04/18/2024] [Indexed: 04/28/2024] Open
Abstract
Visceral leishmaniasis (VL), often referred to as kala-azar, is quite rare in developed countries during pregnancy. Only few studies have evaluated its impact on perinatal outcome. It is caused primarily by Leishmania donovani or Leishmania infantum and presents with a wide spectrum of clinical manifestations from cutaneous ulcers to multisystem disease. Differential diagnosis is challenging as symptoms and signs are insidious, mimicking other diseases. Misdiagnosis can result in severe adverse perinatal outcomes, even maternal/neonatal death. Early treatment with liposomal amphotericin-B (LAmB) is currently the first choice with adequate effectiveness. We report a rare case of VL in a twin pregnancy with onset at the second trimester, presenting with periodic fever with rigors, right flank pain, and gradual dysregulation of all three cell lines. The positive rK39 enzyme-linked immunosorbent assay test confirmed the diagnosis. Treatment with LAmB resulted in clinical improvement within 48 h and in the delivery of two late-preterm healthy neonates with no symptoms or signs of vertical transmission. The one-year follow-up, of the mother and the neonates, was negative for recurrence. To our knowledge, this is the first reported case of VL in a twin pregnancy, and consequently treatment and perinatal outcome are of great importance.

Prenatal diagnosis of 18p deletion and 8p trisomy syndrome: literature review and report of a novel case. BMC Womens Health 2024; 24:241. [PMID: 38622524 PMCID: PMC11017580 DOI: 10.1186/s12905-024-03081-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Accepted: 04/07/2024] [Indexed: 04/17/2024] Open
Abstract
18p deletion syndrome constitutes one of the most frequent autosomal terminal deletion syndromes, affecting one in 50,000 live births. The syndrome has un-specific clinical features which vary significantly between patients and may overlap with other genetic conditions. Its prenatal description is extremely rare as the fetal phenotype is often not present during pregnancy. Trisomy 8p Syndrome is characterized by heterogenous phenotype, with the most frequent components to be cardiac malformation, developmental and intellectual delay. Its prenatal diagnosis is very rare due to the unspecific sonographic features of the affected fetuses. We present a very rare case of a fetus with multiple anomalies diagnosed during the second trimester whose genomic analysis revealed a 18p Deletion and 8p trisomy Syndrome. This is the first case where this combination of DNA mutations has been described prenatally and the second case in general. The presentation of this case, as well as the detailed review of all described cases, aim to expand the existing knowledge regarding this rare condition facilitating its diagnosis in the future.

Breaking Bad News During Prenatal Screening: The Role of Professional Obstetricians and Midwives in Greece. Cureus 2024; 16:e56787. [PMID: 38650784 PMCID: PMC11034892 DOI: 10.7759/cureus.56787] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/23/2024] [Indexed: 04/25/2024] Open
Abstract
INTRODUCTION Breaking bad news is one of the most difficult responsibilities in medical practice. Although medical staff in clinical practice often encounter situations that necessitate the announcement of unpleasant news, there is a lack of training regarding their communication with patients and their families. Effective interaction between medical staff and pregnant women constitutes a crucial component of breaking down unpleasant news. This research aimed to investigate the knowledge and attitude of health professionals, particularly obstetricians, and midwives, regarding the announcement of bad news during prenatal screening. METHODS The study was conducted between September 2017 and April 2018. One hundred professional obstetricians and midwives involved in fetal and prenatal medicine in Greece were part of the study. The study consisted of two parts: the first covered the emotional state of healthcare professionals during the announcement of unpleasant news, and the second covered the appropriate way to inform unpleasant results during prenatal testing. RESULTS In this study, only 41% of the participants considered that they felt comfortable discussing issues related to the diagnosis of an unpleasant result during prenatal testing with the pregnant woman/patient, or her relatives, and 85% accepted that they had experienced feelings of sadness, anxiety, or guilt when announcing unpleasant results. Furthermore, 87% of the participants believed that the non-verbal communication component (eye contact, body language) plays an important role in breaking bad news. Finally, 65% considered that prolonged monitoring of the ultrasound screen during prenatal screening does not increase the anxiety of pregnant women when carried out for a better medical opinion. CONCLUSIONS Delivering bad news during prenatal screening creates stress for the parents. As far as the ethical, cultural, psychological, and legal complicity of healthcare professionals is concerned, communicating unpleasant news has been a subject of discussion by many experts. It is important to understand the concerns of women regarding the risks of counseling.

The Effect of Maternal Diet and Physical Activity on the Epigenome of the Offspring. Genes (Basel) 2024; 15:76. [PMID: 38254965 PMCID: PMC10815371 DOI: 10.3390/genes15010076] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Revised: 12/28/2023] [Accepted: 01/04/2024] [Indexed: 01/24/2024] Open
Abstract
The aim of this review was to examine the current literature regarding the effect of maternal lifestyle interventions (i.e., diet and physical activity) on the epigenome of the offspring. PubMed, Scopus and Cochrane-CENTRAL were screened until 8 July 2023. Only randomized controlled trials (RCTs) where a lifestyle intervention was compared to no intervention (standard care) were included. Outcome variables included DNA methylation, miRNA expression, and histone modifications. A qualitative approach was used for the consideration of the studies' results. Seven studies and 1765 mother-child pairs were assessed. The most common types of intervention were dietary advice, physical activity, and following a specific diet (olive oil). The included studies correlated the lifestyle and physical activity intervention in pregnancy to genome-wide or gene-specific differential methylation and miRNA expression in the cord blood or the placenta. An intervention of diet and physical activity in pregnancy was found to be associated with slight changes in the epigenome (DNA methylation and miRNA expression) in fetal tissues. The regions involved were related to adiposity, metabolic processes, type 2 diabetes, birth weight, or growth. However, not all studies showed significant differences in DNA methylation. Further studies with similar parameters are needed to have robust and comparable results and determine the biological role of such modifications.

Screening vs. no screening for preterm delivery in low-risk singleton pregnancies: comparison by propensity score analysis. Arch Gynecol Obstet 2024; 309:133-138. [PMID: 36580115 PMCID: PMC10770190 DOI: 10.1007/s00404-022-06882-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Accepted: 12/08/2022] [Indexed: 12/30/2022]
Abstract
PURPOSE To compare the effect of a policy of screening for spontaneous preterm delivery (SPD) by transvaginal cervical length (CL) measurement versus a no screening policy in the prevention of severe prematurity. METHODS Retrospective study on low-risk singleton pregnancies examined at 20-24 weeks. Two cohorts, one with SPD screening and the other without screening, were matched using propensity analysis to create the study groups. Women with short CL were treated with vaginal progesterone and/or cervical cerclage/pessary. The outcomes examined were SPD < 32 weeks (SPD 32) and SPD between 20 and 32 weeks (SPD 20-32). RESULTS Screening for SPD was associated with a significant reduction in the rate of SPD at less than 32 weeks (0.3 vs. 0.8%, p = 0.001 in the screened and no screened pregnancies, respectively) and in the rate of SPD 20-32 (0.3 vs. 0.9%, p = 0.005 in the screened and no screened pregnancies, respectively). After adjusting for maternal age, parity, body mass index, smoking and mode of conception, the screening group had significantly lower hazard for SPD 20-32 (HR = 0.36, 95% CI: 0.18-0.75, p = 0.006) and SPD32 (HR = 0.39, 95% CI: 0.19-0.82, p = 0.013). CONCLUSION Screening for SPD by transvaginal CL measurement in mid-pregnancy may reduce the incidence of severe prematurity in low-risk singleton pregnancies.

Abstract
BACKGROUND The examination of the uterine arteries using Doppler in the first trimester of pregnancy serves as a valuable tool for evaluating the uteroplacental circulation. Diabetes mellitus is associated with altered placental implantation and pregnancy-related pathologies, such as preeclampsia. The aim of this study was to compare the uterine arteries' pulsatility indices (UtA PI) in women with diabetes mellitus type 1 (DM1), diabetes mellitus type 2 (DM2), gestational diabetes mellitus (GDM), and uncomplicated pregnancies. METHODS This was a retrospective case-control trial including pregnant women with DM1, DM2, GDM, and uncomplicated pregnancies, presenting for first-trimester ultrasound screening in two tertiary university hospitals between 2013 and 2023. The first-trimester UtA pulsatility index (PI), expressed in multiples of medians (MoMs), was compared between the four groups. RESULTS Out of 15,638 pregnant women, 58 women with DM1, 67 women with DM2, 65 women with GDM, and 65 women with uncomplicated pregnancies were included. The mean UtA PI were 1.00 ± 0.26 MoMs, 1.04 ± 0.32 MoMs, 1.02 ± 0.31 MoMs, and 1.08 ± 0.33 MoMs in pregnant women with DM1, DM2, GDM, and uncomplicated pregnancies, respectively (p > 0.05). CONCLUSIONS Potential alterations in the implantation of the placenta in pregnant women with diabetes were not displayed in the first-trimester pulsatility indices of the uterine arteries, as there were no changes between the groups.

Effect of mode of delivery on perinatal outcome in severe preterm birth: systematic review and meta-analysis. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2023; 62:471-485. [PMID: 37128165 DOI: 10.1002/uog.26241] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/19/2023] [Revised: 04/18/2023] [Accepted: 04/24/2023] [Indexed: 05/03/2023]
Abstract
OBJECTIVE To review the evidence on the effect of mode of delivery on perinatal outcome of fetuses born before 32 weeks' gestation. METHODS MEDLINE, Scopus, Cochrane Central Register of Controlled Trials (CENTRAL), the ClinicalTrials.gov registry and gray literature sources were searched, starting from the year 2000 to reflect contemporary practice in perinatal care. Non-randomized or randomized studies that included singleton fetuses without chromosomal abnormality or major congenital defect delivered vaginally or via Cesarean section were eligible for inclusion in the analysis. Primary outcomes were neonatal death, defined as death in the first 28 days of age, and survival to discharge. Secondary outcomes were other adverse perinatal events. The ROBINS-I tool was used to assess the risk of bias. The overall quality of evidence for the outcomes was assessed according to GRADE. Summary odds ratios (ORs) with 95% CIs were calculated, and random-effects models were used for data synthesis. Subgroup analysis was performed for delivery before 28 weeks, delivery between 28 and 32 weeks and according to fetal presentation at delivery. RESULTS A total of 27 retrospective studies (22 887 neonates) were included in the systematic review and meta-analysis, all of which reported on singleton pregnancies. Among cases born before 28 weeks, vaginal delivery significantly increased the risk of neonatal death of fetuses with any type of presentation (n = 1496) (OR 1.87 (95% CI, 1.05-3.35); I2 = 65%, very low quality of evidence) and of fetuses with breech presentation (n = 733) (OR 3.55 (95% CI, 2.42-5.21); I2 = 21%, moderate quality of evidence). The odds of survival to discharge were significantly decreased among fetuses with breech presentation delivered before 28 weeks (n = 646) (OR 0.36 (95% CI, 0.24-0.54); I2 = 21%, low quality of evidence). Among breech fetuses born between 28 and 32 weeks, vaginal delivery increased the odds of perinatal death (intrapartum and neonatal) (n = 1581) (OR 3.06 (95% CI, 1.47-6.35); I2 = 0%, high quality of evidence). In non-cephalic fetuses born between 24 and 32 weeks, vaginal delivery decreased the odds of survival to discharge (n = 1030) (OR 0.28 (95% CI, 0.19-0.40); I2 = 0%, moderate quality of evidence). No significant effect on mortality of mode of delivery was observed in cephalic fetuses at any gestational age. CONCLUSIONS This systematic review and meta-analysis suggests that vaginal delivery in severe preterm birth is associated with an increased risk of neonatal and perinatal death in breech fetuses, while no significant association was observed for cephalic fetuses. © 2023 The Authors.

Abstract
AIMS To assess the prevalence variation in pregnancy outcomes of the different phenotypes of gestational diabetes mellitus (GDM). MATERIALS Cohort, cross sectional and case control studies grouping together pregnant women with GDM, based on the results of oral glucose tolerance test(OGTT) and reporting pregnancy outcomes in each group, were included. The primary outcomes were (i)large for gestational age and ii)hypertensive disorders of pregnancy (HDP). The secondary outcomes included (i)insulin treatment, ii)admission to neonatal intensive care unit, iii)preterm birth, iv)small for gestational age and v)caesarean section. The pooled proportions of the outcomes of interest were calculated for each phenotype. RESULTS 8 studies (n = 20.928 women with GDM) were included. The pooled prevalence of LGA, HDP and insulin treatment were 20 %, 8 % and 24 % respectively in women with abnormal fasting plasma glucose,10 %, 6 % and 9 % respectively in women with abnormal post-load plasma glucose and 14 %,14 % and 30 % in women with abnormal combined plasma glucose. CONCLUSIONS Pregnant women with abnormal fasting plasma glucose, present with the highest prevalence of LGA, while those with abnormal combined plasma glucose, present with the highest prevalence of HDP. Pregnant women with abnormal post-load plasma glucose present with the lowest need for insulin treatment.

Tumor Markers and Their Diagnostic Significance in Ovarian Cancer. Life (Basel) 2023; 13:1689. [PMID: 37629546 PMCID: PMC10455076 DOI: 10.3390/life13081689] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2023] [Revised: 07/27/2023] [Accepted: 08/03/2023] [Indexed: 08/27/2023] Open
Abstract
Ovarian cancer (OC) is characterized by silent progression and late-stage diagnosis. It is critical to detect and accurately diagnose the disease early to improve survival rates. Tumor markers have emerged as valuable tools in the diagnosis and management of OC, offering non-invasive and cost-effective options for screening, monitoring, and prognosis. PURPOSE This paper explores the diagnostic importance of various tumor markers including CA-125, CA15-3, CA 19-9, HE4,hCG, inhibin, AFP, and LDH, and their impact on disease monitoring and treatment response assessment. METHODS Article searches were performed on PubMed, Scopus, and Google Scholar. Keywords used for the searching process were "Ovarian cancer", "Cancer biomarkers", "Early detection", "Cancer diagnosis", "CA-125","CA 15-3","CA 19-9", "HE4","hCG", "inhibin", "AFP", "LDH", and others. RESULTS HE4, when combined with CA-125, shows improved sensitivity and specificity, particularly in early-stage detection. Additionally, hCG holds promise as a prognostic marker, aiding treatment response prediction and outcome assessment. Novel markers like microRNAs, DNA methylation patterns, and circulating tumor cells offer potential for enhanced diagnostic accuracy and personalized management. Integrating these markers into a comprehensive panel may improve sensitivity and specificity in ovarian cancer diagnosis. However, careful interpretation of tumor marker results is necessary, considering factors such as age, menopausal status, and comorbidities. Further research is needed to validate and refine diagnostic algorithms, optimizing the clinical significance of tumor markers in ovarian cancer management. In conclusion, tumor markers such as CA-125, CA15-3, CA 19-9, HE4, and hCG provide valuable insights into ovarian cancer diagnosis, monitoring, and prognosis, with the potential to enhance early detection.

Abstract
Preeclampsia is a multisystemic clinical syndrome characterized by the appearance of new-onset hypertension and proteinuria or hypertension and end organ dysfunction even without proteinuria after 20 weeks of pregnancy or postpartum. Residing at the severe end of the spectrum of the hypertensive disorders of pregnancy, preeclampsia occurs in 3 to 8% of pregnancies worldwide and is a major cause of maternal and perinatal morbidity and mortality, accounting for 8-10% of all preterm births. The mechanism whereby preeclampsia increases the risk of the neurodevelopmental, cardiovascular, and metabolic morbidity of the mother's offspring is not well known, but it is possible that the preeclamptic environment induces epigenetic changes that adversely affect developmental plasticity. These developmental changes are crucial for optimal fetal growth and survival but may lead to an increased risk of chronic morbidity in childhood and even later in life. The aim of this review is to summarize both the short- and long-term effects of preeclampsia on offspring based on the current literature.

Abstract
Several factors during childhood and adolescence are thought to be associated with the development of proliferative benign breast diseases and breast cancer in adulthood. In order to identify them, the authors conducted an extensive review of the literature up to October 2022, searching for clinical studies, reports, and guidelines in English. A thorough Medline/Pubmed and Google scholar database research was performed, investigating the link between diet, exercise, age of menarche, body mass index, ionizing radiation exposure during childhood and adolescence, and proliferative breast diseases and breast cancer in adulthood. A list of keywords, including breast disorders, adolescence, childhood, and breast cancer was included in our search algorithm. Numerous studies concede that the development of breast disease in adulthood is influenced by various risk factors, whose influence begins during early childhood and adolescence.

Abstract
AIMS This study aims to investigate the different phenotypes of Gestational Diabetes Mellitus (GDM), in correlation to preeclampsia and uterine arteries resistance. MATERIALS This is a prospective cohort study including women with and without GDM per the IADPSG criteria. Three phenotypes of GDM emerged, women with only abnormal fasting (AF) glucose levels, women with only abnormal post-load (AP) glucose levels at 60' and/or 120' and women with abnormal combined (AC) fasting and post-load glucose values. All women underwent uterine arteries doppler examination in the three trimesters and assessed for preeclampsia development. Linear regression was used to express the trajectories of uterine arteries resistance throughout the pregnancy. RESULTS 6928 pregnant women were included, 5274 without GDM and 1654 with GDM. 546, 781 and 327 of GDM pregnancies presented with AF, AP and AC phenotypes respectively. Prevalence of preeclampsia was 17.9%, 26.8% and 30% in the AF, AP and AC phenotypes respectively (p < 0.001). In women who developed preeclampsia, AC phenotype presented with statistically different trajectory of Uterine Arteries Pulsatility Index Percentiles b = 0.129 than women without GDM and women with AP GDM phenotype b = -0.015 and b = -0.016 respectively. CONCLUSIONS The combined abnormal phenotype presents with the highest rate of preeclampsia and the most distinct pattern of uterine arteries resistance.

Prenatal Identification of a Novel Mutation in the MCPH1 Gene Associated with Autosomal Recessive Primary Microcephaly (MCPH) Using Next Generation Sequencing (NGS): A Case Report and Review of the Literature. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9121879. [PMID: 36553323 PMCID: PMC9776937 DOI: 10.3390/children9121879] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Revised: 11/19/2022] [Accepted: 11/27/2022] [Indexed: 12/03/2022]
Abstract
BACKGROUND MCPH1 is known as the microcephalin gene (OMIM: *607117), of which the encoding protein is a basic regulator of chromosome condensation (BCRT-BRCA1 C-terminus). The microcephalin protein is made up of three BCRT domains and conserved tandem repeats of interacting phospho-peptides. There is a strong connection between mutations of the MCPH1 gene and reduced brain growth. Specifically, individuals with such mutations have underdeveloped brains, varying levels of mental retardation, delayed speech and poor language skills. METHODS In this article, a family with two affected fetuses presenting a mutation of the MCPH1 gene is reported. During the first trimester ultrasound of the second pregnancy, the measure of nuchal translucency was increased (NT = 3.1 mm) and, therefore, the risk for chromosomal abnormalities was high. Chorionic villi sampling (CVS) was then performed. Afterwards, fetal karyotyping and Next Generation Sequencing were carried out. Afterwards, NGS was also performed in a preserved sample of the first fetus which was terminated due to microcephaly. RESULTS In this case, the fetuses had a novel homozygous mutation of the MCPH1 gene (c.348del). Their parents were heterozygous for the mutation. The fetuses showed severe microcephaly. Because of the splice sites in introns, this mutation causes the forming of dysfunctional proteins which lack crucial domains of the C-terminus. CONCLUSION Our findings portray an association between the new MCPH1 mutation (c.348del) and the clinical features of autosomal recessive primary microcephaly (MCPH), contributing to a broader spectrum related to these pathologies. To our knowledge, this is the first prenatal diagnosis of MCPH due to a novel MCPH1 mutation.

Abstract
Purpose: To provide an overview and critical analysis of the literature related to the circulating androgen levels of daughters of PCOS mothers during prepubertal and pubertal stage who have not yet been diagnosed with PCOS or precocious puberty. Methods: We critically considered and meta-analyzed observational studies comparing androgens concentration in daughters of PCOS mothers compared to daughters of mothers without PCOS. A literature search was conducted in MEDLINE, Scopus and other sources from 01/09/2021 until 01/12/2021. The study followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). The primary outcome included total testosterone levels whereas the secondary outcomes included 17a-hydroxyprogesterone (17-OHP), androstenedione (Δ4Α) and Sex Hormone Binding Globulin (SHBG) levels respectively. Results: Our search yielded 1073 studies, 9 of which were included in our analysis. The results are presented differently according to pubertal stage. Pubertal daughters of PCOS mothers exhibited significantly higher total testosterone (pooled mean difference 14.95 (95%CI: 6.98 to 22.93), higher 17-OHP (pooled mean difference 0.11 (95%CI: 0.02 to 0.20) and lower SHBG levels (pooled mean difference -10.48 (95%CI: -16.46 to -4.61). Instead, prepubertal daughters of PCOS mothers presented greater SHBG levels (pooled mean difference 7.79 (95%CI: 0.03 to 15.54) compared to controls. No difference was found in Δ4Α levels in both groups. Conclusion: The onset of puberty is a critical point in the development of the disease and an early intervention may be imperative.

Familial Aggregation of a Novel Missense Variant of COL2A1 Gene Associated with Short Extremities: Case Report and Review of the Literature. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9081229. [PMID: 36010119 PMCID: PMC9406900 DOI: 10.3390/children9081229] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Revised: 04/16/2022] [Accepted: 04/16/2022] [Indexed: 11/25/2022]
Abstract
We present two cases of family members (first cousins) with short extremities caused by a novel variant of COL2A1 gene (NM_001844.5). Case 1 description: A 29-year-old woman presented in her first pregnancy for a second trimester anomaly scan at 23 weeks of gestation. Fetal long bones were measured below the third centile for gestational age. Follow-up scans revealed fetal long bone growth deceleration. Initial genetic work-up was negative and the rest of the maternal follow-up was unremarkable. A male baby weighing 3180 g was delivered at 39 weeks and 4 days of gestation. Case 2 description: A 33-year-old pregnant woman presented for a routine second trimester anomaly scan at 20 weeks and 4 days of gestation. All fetal measurements were appropriate for the gestational age. The routine growth scan performed at 32 weeks showed fetal long bone measurements below the third centile for gestational age, while the follow-up growth scan at 36 weeks and 4 days of gestation revealed consistent, below the third centile, fetal long bone growth. Given that the fetuses of these two cases were related (first cousins), whole exome sequencing (WES) was performed on Case 2. WES revealed a novel heterozygous missense variant c.1132G>A (p. Gly378Ser) of COL2A1 gene (NM_001844.5). Subsequently, targeted genetic sequencing for the variant was performed on Case 1 and the same novel variant was found. Targeted sequencing revealed the same variant in the mother of Case 1 and the father of Case 2 (siblings). A female baby weighing 3200 g was delivered at 40 weeks and 4 days of gestation.

Associations between Maternal and Offspring Hair Cortisol Concentrations and Child Behavioral Symptoms in Mother-Child Pairs with Perinatal Mental Disorders. CHILDREN 2022; 9:children9060810. [PMID: 35740747 PMCID: PMC9221619 DOI: 10.3390/children9060810] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/27/2022] [Revised: 05/25/2022] [Accepted: 05/28/2022] [Indexed: 12/02/2022]
Abstract
Maternal perinatal mental disorders (PMD) are associated with developmental and behavioral problems in children, probably mediated by the programming of the hypothalamic–pituitary–adrenal (HPA) axis. Increased cortisol concentrations during the antenatal and perinatal periods have been related to long-term effects on children’s behavior and stress response. We aimed to investigate the association of hair cortisol concentrations (HCC) between mothers, with (n = 16) and without PMD (n = 30), and their children, aged between 18 and 48 months. Participants were evaluated with a clinical interview and questionnaires for the Depression Anxiety Stress Scale and the Child Behavior Checklist for ages 1½–5. Maternal and child HCCs were compared between the two groups. Children of the PMD group had increased symptoms of attention deficit hyperactivity disorder. A positive linear association between maternal and child HCC was observed only in the total sample of mother–child dyads and the control group. In the PMD group, children’s HCCs were significantly associated with child anxiety/depression symptoms. Aggressive behavior and oppositional/defiant problems correlated significantly with children’s own HCCs, and their mother’s too. These findings suggest that a chronic dysregulation of maternal and child HPA axis and their associations in the PMD dyads may underlie the linkage among prolonged maternal stress, child behavioral/emotional problems and stress responses.

Physical Health, Media Use, Stress, and Mental Health in Pregnant Women during the COVID-19 Pandemic. Diagnostics (Basel) 2022; 12:diagnostics12051125. [PMID: 35626281 PMCID: PMC9140022 DOI: 10.3390/diagnostics12051125] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Revised: 04/25/2022] [Accepted: 04/27/2022] [Indexed: 02/01/2023] Open
Abstract
Background: The COVID-19 pandemic has led to significant changes in the care of pregnant women and their fetuses. Emerging data show elevated depression and anxiety symptoms among pregnant women. Aims: The purpose of this article is to investigate the psychological and behavioral impact of the COVID-19 pandemic on pregnant women in Greece during the first national lockdown. Methods: We used a cross-sectional, anonymous survey to collect data in two fetal medicine clinics in the largest urban centers of Greece during the months of April and May 2020. The questionnaire was largely based on the CoRonavIruS Health Impact Survey (CRISIS), and assessed sociodemographic characteristics, general health and obstetric data and COVID-19-related worries and life changes. Mood symptoms, substance use and lifestyle behaviors were assessed at two time points (3 months prior to the pandemic and the 2 weeks before taking the survey), while perceived stress was measured with the perceived stress scale (PSS-14). Results: A total of 308 pregnant women (Mage = 34.72), with a mean gestation of 21.19 weeks participated in the study. Over one-third of the women found COVID-19 restrictions stressful, and their highest COVID-19-related worry was having to be isolated from their baby. Mean PSS-14 score was 21.94, suggesting moderate stress. The strongest predictors of stress were physical and mental health status before COVID-19 and having experienced a stressful life event during their pregnancy. Compared to 3 months before the pandemic, women reported higher scores on mood symptoms (p < 0.001), TV use (p = 0.01) and social media use (p = 0.031) in the last 2 weeks before taking the survey. Conclusion: Our study provides important preliminary evidence of the negative impact of the COVID-19 pandemic and the lockdown on pregnant women’s well-being and functioning.

The impact of Mayer–Rokitansky–Küster–Hauser Syndrome on Psychology, Quality of Life, and Sexual Life of Patients: A Systematic Review. CHILDREN 2022; 9:children9040484. [PMID: 35455528 PMCID: PMC9025055 DOI: 10.3390/children9040484] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Revised: 03/21/2022] [Accepted: 03/22/2022] [Indexed: 11/16/2022]
Abstract
Background: Mayer–Rokitansky–Küster–Hauser (MRKH) syndrome is a rare congenital syndrome characterized by uterovaginal agenesis. Most patients are diagnosed during adolescence, when body image and sexual identity are shaped. Our main objective was to investigate how MRKH syndrome affects psychology, quality of life (QoL), and the sexual life of patients compared with non-affected individuals. Methods: Original peer-reviewed research papers examining psychological outcomes, QoL, and sexual function of MRKH patients were searched in PubMed. Titles, abstracts, and full text from potentially eligible records were reviewed by two independent reviewers. Case reports and papers published not in English were excluded. Results: Our search identified 63 records, of which 20 were included: 10 examined psychological and psychosocial outcomes, 14 examined sexual function outcomes, and 6 examined QoL outcomes. Results may be affected by selection bias and confounding due to differences between MRKH patients and controls. Conclusions: MRKH could be associated with a higher prevalence of anxiety and depression symptoms and social insecurity compared with women of a similar age without the condition. MRKH could also be associated with greater pain and discomfort during sexual intercourse and limitations in arousal, lubrication, and orgasm. MRKH patients more commonly experience impairment of mental-health-related QoL, but physical-health-related QoL is not affected.

Preeclampsia and Cerebral Palsy in Offspring. CHILDREN 2022; 9:children9030385.

Abstract
The aim of this systematic review and meta-analysis is to examine the association between exposure to preeclampsia during pregnancy and the occurrence of cerebral palsy in offspring. For this reason, the authors searched PubMed/Medline, EMBASE, and Google Scholar databases (end-of-search: 22 November 2021) and identified the most relevant studies. Then, a meta-analysis of all the eligible studies was performed. Subgroup and meta-regression analyses by study design, degree of adjustment, and geographical region were also conducted. A total of 10 studies were finally included, and no statistical significance was noted in the association between preeclampsia and cerebral palsy (pooled OR = 1.16, 95% CI: 0.77–1.74). The subgroup of studies that provided adjusted odds ratios for any variable except for gestational age showed a statistically significant association (pooled OR = 1.62, 95% CI: 1.36–1.93), whereas the association dissipated in studies also adjusting for gestational age (pooled OR = 1.63, 95% CI: 0.48–5.50). In conclusion, it seems that preeclampsia is not associated with cerebral palsy independently of gestational age; however, further research is needed to shed light on this topic.

Abstract
OBJECTIVE To correlate the distinct diagnostic criteria of polycystic ovary syndrome (PCOS) with the development of maternal and neonatal complications. DESIGN Systematic review and meta-analysis. SETTING Not applicable. PATIENT(S) Pregnant women with PCOS. INTERVENTION(S) Maternal and neonatal complications were compared among women with PCOS diagnosed with different criteria. MAIN OUTCOME MEASURE(S) The primary outcomes of gestational diabetes mellitus and preeclampsia (PE) were assessed for every diagnostic criterion. RESULT(S) Seventy-nine studies were included. Regarding gestational diabetes, the overall pooled prevalence was 14% (95% confidence interval [CI], 11%-18%; I2, 97%), reaching the highest level when polycystic ovarian morphology on ultrasound and 1 of the remaining 2 Rotterdam criteria (1/2 Rotterdam criteria) were used (18%; 95% CI, 13%-24%; I2, 20%) and the lowest when polycystic morphology on ultrasound and hyperandrogenism were used (3%; 95% CI, 0%-19%; I2, not applicable). Regarding PE, the overall pooled prevalence was 5% (95% CI, 4%-7%; I2, 82%). The highest PE prevalence was reported when the National Institutes of Health criteria were used (14%; 95% CI, 5%-33%; I2, 90%) and the lowest when menstrual irregularities and 1 of the 2 Rotterdam criteria were used (2%; 95% CI, 1%-3%; I2, not applicable). CONCLUSION(S) The prevalence of gestational diabetes mellitus in pregnant women with PCOS does not differ according to the criteria used; however, women diagnosed with PCOS per the National Institutes of Health criteria are at higher risk of PE.

Abstract
INTRODUCTION The identification of pregnant women with Gestational Diabetes Mellitus (GDM) who will require insulin therapy, may modify their management to closer monitoring and probable early interventions. The aim of the study was to develop a predictive model for the necessity of insulin treatment in women with GDM. MATERIALS AND METHODS This was a prospective cohort study. Data from 775 women diagnosed with GDM per the IADPSG criteria were analyzed using logistic regression and a machine learning algorithm, the Classification and Regression Trees (CART). Potential predictors routinely recorded at follow-up visits were tested and used for the development of the model. The resultant model was externally validated using the data from two different perinatology clinics. RESULTS Preconceptional maternal BMI and morning fasting blood glucose levels at baseline and at 1 h during an Oral Glucose Tolerance Test (OGTT) were independent significant predictors for the treatment modality of GDM. Baseline blood glucose greater than 98 mg/dl and preconceptional maternal Body Mass Index (BMI) between 26 and 31 kg/height2 increased substantially the probability of insulin therapy (odds ratio [OR] 4.04, 95% confidence interval [CI] CI 2.65-6.17 and 2.21, 95%CI 1.42-3.43, respectively). The area under the curve (AUC) for the internal and external validation of the predictive model was 0.74 and 0.77, respectively. CONCLUSIONS A simple model based on maternal characteristics and the values of an OGTT can predict the need for insulin treatment with accuracy. Overweight women with an abnormal baseline blood glucose at OGTT are at high likelihood for insulin treatment. KEY MESSAGE Fifteen to 30% of women with Gestational Diabetes Mellitus (GDM) require insulin therapy. Overweight women with baseline blood glucose greater than 98 mg/dl at OGTT are at increased risk for insulin treatment and close monitoring and increased physical exercise are required.

Abstract
Fetal brain is extremely plastic and vulnerable to environmental influences that may have long-term impact on health and development of the offspring. Both the Hypothalamic-Pituitary-Adrenal (HPA) and the Hypothalamic-Pituitary-Thyroid (HPT) axes are involved in stress responses, whereas, their final effectors, the Glucocorticoids (GCs) and the Thyroid Hormones (TH s), mediate several fundamental processes involved in neurodevelopment. The effects of these hormones on brain development are found to be time and dose-dependent. Regarding THs, the developing fetus depends on maternal supply of hormones, especially in the first half of pregnancy. It is acknowledged that inadequate or excess concentrations of both GCs and THs can separately cause abnormalities in the neuronal and glial structures and functions, with subsequent detrimental effects on postnatal neurocognitive function. Studies are focused on the direct impact of maternal stress and GC excess on growth and neurodevelopment of the offspring. Of particular interest, as results from recent literature data, is building understanding on how chronic stress and alterations of the HPA axis interacts and influences HPT axis and TH production. Animal studies have shown that increased GC concentrations related to maternal stress, most likely reduce maternal and thus fetal circulating THs, either directly or through modifications in the expression of placental enzymes responsible for regulating hormone levels in fetal microenvironment. The purpose of this review is to provide an update on data regarding maternal stress and its impact on fetal neurodevelopment, giving particular emphasis in the interaction of two axes and the subsequent thyroid dysfunction resulting from such circumstances.

Abstract
Baraitser - Winter Cerebrofrontofacial Syndrome (BWCFF) is a rare disorder characterized by facial dysmorphism and mental retardation of varying grades. The clinical phenotype of BWCFF indicates variable phenotypic expression involving various congenital malformations such as cardiac, renal and musculoskeletal abnormalities. Nevertheless, the prenatal presentation of BWCFF is rarely described, making prenatal diagnosis challenging. This report describes a prenatal diagnosis of BWCFF syndrome to date; a case of a fetus with intrauterine growth restriction, increased nuchal fold, bilateral hydronerphosis, rocker bottom foot and clubfoot detected on Anomaly Scan is outlined. Molecular karyotype failed to detect any abnormality. Assessment with Next Generation Sequencing was then performed, revealing a heterozygous de novo mutation in ACTB gene setting the diagnosis of BWCFF.

Abstract
Background Fetal growth restriction (FGR) has been associated with adverse perinatal outcomes and epigenetic modifications that impact gene expression leading to permanent changes of fetal metabolic pathways and thereby influence development of disease in childhood and adult life. In this study, we investigated the result of maternal food restriction on liver protein expression in Wistar male newborn pups. Materials & Methods Ten (n = 10) timed pregnant Wistar rats on their 14th day of gestation were randomly assigned to either control (n = 4) or food restricted group (n = 6). The control group had ad libitum access to food. In the food restricted group, maternal diet was limited in a moderate fashion (50%) from day 15 of pregnancy until delivery. All rats delivered spontaneously on day 21 and newborn pups were immediately weighed. Pups born to normally nourished mothers were considered as controls, while pups born to food restricted mothers were subdivided into two groups, based on their birth weight: growth restricted (FGR) and appropriately grown (non-FGR). Rats were euthanized immediately after birth and liver tissues of 11 randomly selected male offspring (FGR n = 4, non-FGR n = 4, control n = 3) were collected and analyzed using quantitative proteomics. Results In total 6,665 proteins were profiled. Of these, 451 and 751 were differentially expressed in FGR and non-FGR vs. control, respectively, whereas 229 proteins were commonly expressed. Bioinformatics analysis of the differentially expressed proteins (DEPs) in FGR vs. control revealed induction of the super-pathway of cholesterol biosynthesis and inhibition of thyroid hormone metabolism, fatty acid beta oxidation and apelin liver signaling pathway. Analysis of DEPs in non-FGR vs. control groups showed inhibition of thyroid hormone metabolism, fatty acid beta oxidation, and apelin liver signaling pathway. Conclusion This study demonstrates the impact of prenatal food restriction on the proteomic liver profile of FGR and non-FGR offspring underlying the importance of both prenatal adversities and birth weight on liver-dependent postnatal disease.

Abstract
Background Fetal growth restriction (FGR) has been associated with a higher risk of developing adverse perinatal outcomes and distinct neurodevelopmental and neurobehavioral disorders. The aim of the present study was to investigate the impact of prenatal food restriction on the brain proteome in both FGR and appropriately grown rats and to identify potential pathways connecting maternal malnutrition with altered brain development. Methods Ten time-dated pregnant Wistar rats were housed individually at their 12th day of gestation. On the 15th day of gestation, the rats were randomly divided into two groups, namely the food restricted one (n = 6) and the control group (n = 4). From days 15 to 21 the control group had unlimited access to food and the food restricted group was given half the amount of food that was on average consumed by the control group, based on measurements taken place the day before. On the 21st day of gestation, all rats delivered spontaneously and after birth all newborn pups of the food restricted group were weighed and matched as appropriately grown (non-FGR) or growth restricted (FGR) and brain tissues were immediately collected. A multiplex experiment was performed analyzing brain tissues from 4 FGR, 4 non-FGR, and 3 control male offspring. Differentially expressed proteins (DEPs) were subjected to bioinformatics analysis in order to identify over-represented processes. Results Proteomic analysis resulted in the profiling of 3,964 proteins. Gene ontology analysis of the common DEPs using DAVID (https://david.ncifcrf.gov/) showed significant enrichment for terms related to cellular morphology, learning, memory and positive regulation of NF-kappaB signaling. Ingenuity Pathway Analysis showed significant induction of inflammation in FGR pups, whereas significant induction of cell migration and cell spreading were observed in non-FGR pups. Conclusion This study demonstrated that in both FGR and non-FGR neonates, a range of adaptive neurodevelopmental processes takes place, which may result in altered cellular morphology, chronic stress, poor memory and learning outcomes. Furthermore, this study highlighted that not only FGR, but also appropriately grown pups, which have been exposed to prenatal food deprivation may be at increased risk for impaired cognitive and developmental outcomes.

Abstract
Mutations in the skeletal muscle ryanodine receptor (RYR1) gene have been linked to malignant hyperthermia susceptibility, central core disease, and minicore myopathy with external ophthalmoplegia. RYR1 is an intracellular calcium release channel and plays a crucial role in the sarcoplasmic reticulum and transverse tubule connection. Here, we report 2 fetuses from the same parents with compound heterozygous mutations in the RYR1 gene (c.10347+1G>A and c.10456-2Α>G) who presented with fetal akinesia and polyhydramnios at 27 and 19 weeks of gestation with intrauterine growth restriction in the third pregnancy. The prospective parents of the fetuses were heterozygous carriers for c.10456-2Α>G (mother) and c.10347+1G>A (father). Both mutations affect splice sites resulting in dysfunctional protein forms probably missing crucial domains of the C-terminus. Our findings reveal a new RYR1 splice site mutation (c.10456-2Α>G) that may be associated with the clinical features of myopathies, expanding the RYR1 spectrum related to these pathologies.

[PMID: 32027925 DOI: 10.1016/j.diabres.2020.108048] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2019] [Revised: 01/19/2020] [Accepted: 01/31/2020] [Indexed: 11/22/2022]
Abstract
AIMS This study aimed to investigate whether pregnancies complicated by gestational diabetes mellitus (GDM) present differences in the outcomes according to the findings on oral glucose tolerance test (OGTT), including fasting, post-load or combined abnormal blood glucose. MATERIALS This was a prospective cohort study including 831 singleton pregnancies with GDM per the IADPSG criteria. According to their fasting blood glucose value on OGTT the women were categorized in three groups: (i) GDM women with fasting plasma glucose levels > 92 mg/dl and normal post-load values (T0 abnormal group), (ii) patients with abnormal values at 60' and/or 120' and normal fasting values (T-post group) and (iii) patients with combined fasting and post-load abnormal blood glucose values (T-comb). Regression analysis was used to test the independent contribution of the different groups, along with maternal and fetal characteristics, in prediction of (i) large for gestational age (LGA), (ii) need for insulin treatment and (iii) birthweight centile. RESULTS GDM with abnormal fasting blood glucose was an independent risk factor for LGA (OR 2.91, 95% CI 1.33-6.36) and was associated with higher birthweight centile (10.25, 95% CI 0.27-20.25). GDM with combined fasting and post-load abnormal blood glucose was an independent risk factor for insulin treatment (OR 2.94, 95% CI 1.93-4.47). CONCLUSIONS Women with GDM and abnormal fasting blood glucose are at increased risk for large for gestational age neonates, while women with GDM and combined fasting and post-load abnormal blood glucose are at increased risk for insulin therapy.

Prevention of gestational diabetes mellitus in overweight or obese pregnant women: A network meta-analysis. Diabetes Res Clin Pract 2019; 158:107924. [PMID: 31738997 DOI: 10.1016/j.diabres.2019.107924] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/02/2019] [Revised: 10/26/2019] [Accepted: 11/06/2019] [Indexed: 12/27/2022]
Abstract
AIMS Several interventions have been implemented to prevent the development of gestational diabetes mellitus (GDM) in obese pregnant women, including physical exercise programs, and administration of metformin, vitamin D and probiotics. The aim of this network meta-analysis was to compare the efficiency of these interventions and identify the optimal. MATERIALS A network meta-analysis of randomized trials was performed comparing the different interventions for the development of GDM in overweight or obese women, either to each other or placebo/no intervention. A search was conducted in four electronic databases and grey literature sources. The primary outcome was the development of GDM; secondary outcomes were other complications of pregnancy. RESULTS The meta-analysis included 23 studies (4237 participants). None of the interventions was superior compared with placebo/no intervention for the prevention of GDM. Metformin and physical exercise were superior to placebo/no intervention for gestational weight gain (MD -1.21, 95% CI -2.14 to -0.28 and MD -0.96, 95% CI -1.69 to -0.22, respectively). Metformin was superior to placebo/no intervention for caesarean sections and admission to NICU. CONCLUSIONS Interventions aiming to prevent the development of GDM in overweight/obese women are not effective, when applied during pregnancy.

Abstract
INTRODUCTION To assess the perinatal outcome of fetuses dropping by ≥50 estimated fetal weight (EFW) centiles between the second and third trimester. METHODS Singleton pregnancies progressing after 32 + 0 weeks, who had their second- and third-trimester scans at our institutions were enrolled in the study. The perinatal outcome of AGA fetuses crossing more than 50 centiles was compared to that of fetuses with FGR, small for gestational age (SGA) and nondecelerating appropriate for gestational age (AGA). The primary perinatal outcomes were perinatal death, neonatal intensive care (NICU) admission and emergency cesarean section (CS). The rates of these outcomes were compared between the four groups and regression analysis was performed to account for maternal and fetal confounders. RESULTS Our analysis included 4394 cases. Compared to nondecelerating SGA, fetuses crossing ≥50 centiles had higher rates of NICU admission (odds ratio [OR] 1.8, 95% confidence interval [CI] CI 1.1-3.1) and perinatal death (OR 3.8, 95%CI 1.3-11.4). Regression analysis showed that significant independent predictors for NICU admission included maternal age, gestational age at birth and FGR (area under the curve [AUC] 0.851), whereas significant predictors for perinatal death included maternal age, gestational age at birth, decelerating growth ≥50 centiles, conception through ART and third-trimester CPR centile (AUC 0.801). CONCLUSION AGA fetuses that cross >50 EFW centiles between the second and third trimester are at increased risk of adverse perinatal outcome and it seems advisable that they are followed up as typical FGR cases.

Abstract
In this report, a patient carrying a 650 kb deletion and a 759 kb duplication of chromosomal 21q22.3 region was described. Facial dysmorphic features, hypotonia, short stature, learning impairment, autism spectrum disorder, anxiety and depression were observed clinical characteristics. Mentioned copy number variants were the shortest in length reported so far. The current study hypothesized that the presence of a susceptibility locus for autism spectrum disorder associated with depression and anxiety may be located in a 200 kb region between the PCNT and PRMT2 genes. The current study aimed to provide insight into the human genome morbidity map of chromosome 21.

First-trimester and combined first- and second-trimester prediction of small-for-gestational age and late fetal growth restriction. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2019; 53:55-61. [PMID: 29573501 DOI: 10.1002/uog.19055] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/31/2017] [Revised: 02/16/2018] [Accepted: 03/13/2018] [Indexed: 06/08/2023]
Abstract
OBJECTIVE To develop a first-trimester or combined first- and second-trimester screening algorithm for the prediction of small-for-gestational age (SGA) and late fetal growth restriction (FGR). METHODS This was a retrospective study of women with singleton pregnancy, who underwent routine first-, second- and third-trimester ultrasound assessment. Late FGR was defined, at ≥ 32 weeks' gestation in the absence of congenital anomalies, as either (i) estimated fetal weight (EFW) or birth weight (BW) < 3rd centile, or (ii) EFW < 10th centile and either uterine artery mean pulsatility index (UtA-PI) > 95th centile or cerebroplacental ratio (CPR) < 5th centile. Neonates with BW < 10th centile, regardless of prenatal parameters, were defined as SGA. The predictive effectiveness of maternal and first- and second-trimester factors was tested using logistic regression and receiver-operating characteristics curve analyses. RESULTS A total of 3520 fetuses were included (late FGR, n = 109 (3.1%); SGA, n = 292 (8.3%)). Of the late FGR cases, 56 (1.6%) fulfilled the antenatal criteria (EFW < 3rd centile or EFW < 10th centile plus abnormal UtA-PI or CPR) and were defined as prenatally detected late FGR. A first-trimester screening model (comprising conception method, smoking status, maternal height, pregnancy-associated plasma protein-A (PAPP-A) and UtA-PI) could predict 50.0% of the prenatally diagnosed and 36.7% of the overall late FGR fetuses for a 10% false-positive rate (FPR). A model combining first- and second-trimester screening parameters (conception method, smoking status, PAPP-A, second- trimester EFW, head circumference/abdominal circumference ratio and UtA-PI) could predict 78.6% of the prenatally detected, and 59.6% of the overall late FGR fetuses, for a 10% FPR (area under the curve 0.901 (95% CI, 0.856-0.947) and 0.855 (95% CI, 0.818-0.891), respectively). The prediction of SGA was suboptimal for both first-trimester and combined screening. CONCLUSIONS A simple model combining maternal and first- and second-trimester predictors can detect 60% of fetuses that will develop late FGR, and 79% of those fetuses that will be classified prenatally as late FGR, for a 10% FPR.

Abstract
OBJECTIVE The study aims to evaluate the predictive value of first trimester placental volume in pregnancies destined to develop fetal growth restriction (FGR) and preeclampsia (PE). METHODS Prospective observational study including placentas from 34 FGR, 12 PE, 15 GH (gestational hypertension) pregnancies, and 265 controls. Placental volume (PV) was obtained using VOCAL technique, and a z score was calculated (z-PV). The association of PV with other first trimester variables and maternal characteristics was assessed with Spearman's correlation. RESULTS PV increased exponentially with crown-rump length (CRL) and was unrelated to maternal factors (weight, age, parity, and smoking status) as well as first trimester uterine artery Doppler, free β-hCG, nuchal translucency, or fetal heart rate. However, PV was positively associated with maternal height, CRL, PAPP-A, and birth weight. z-PV was a strong predictor for FGR with abnormal fetal Dopplers (AUC = 0.9472, P < 0.001). z-PV provided moderate prediction of FGR with normal fetal Dopplers (AUC = 0.8396, P < 0.001), PE (AUC = 0.8312, P < 0.001), and GH (AUC = 0.7640, P < 0.001). The addition of maternal weight, PAPP-A, β-hCG, and uterine artery Doppler improved our models. CONCLUSION At 11 to 14 weeks, PV is an independent predictor of pregnancy complications related to placental insufficiency, and the predictive ability is greater for FGR pregnancies with abnormal fetal Dopplers.

Abstract
BACKGROUND Foetal growth monitoring is an essential component of prenatal care with postnatal impact. The aim of the study was to construct reference ranges for foetal biometric parameters in Greek foetuses and to compare them with previously published models. MATERIALS AND METHODS Measurements from 1200 Greek foetuses were used to construct normal curves for biparietal diameter (BPD), occipitofrontal diameter (OFD), head circumference (HC), abdominal circumference (AC), femoral length (FL) and the BPD/FL ratio according to the methodology described by Royston and Wright (1998). The model was validated in a second group of 1200 different foetuses using analysis of the corresponding standardized residuals (z-scores). The z-scores which were derived by our model were compared to those calculated using previously published models from other populations. RESULTS BPD, OFD, HC, AC, FL and the BPD/FL ratio are accurately described by simple quadratic equations (R(2) > 0·96 for most of the parameters tested). Statistically significant differences were observed for most of the z-scores when our models were compared to previously published models. Less than 10% of our foetuses were < 5th or > 95th centile of the latter models. About 10% of our foetuses were > 95th centile for FL and HC when the INTERGROWTH-21st formulas were used. CONCLUSION We present national foetal biometric references. Using charts from other populations (including INTERGROWTH-21st) may be unrepresentative of local populations and lead to misclassification of foetal growth status.

Abstract
The aim of the study was to examine interleukin-6 (IL-6) maternal serum concentration at 11 to 14 gestational weeks in normal pregnancies and pregnancies complicated by gestational diabetes mellitus (GDM) and to create first trimester prediction models for GDM. Case-control study conducted in a Fetal Medicine Unit. Study population included 40 GDM cases and 94 controls. Maternal characteristics, first trimester ultrasound markers, biochemical indices, and IL-6 levels were used for our analysis. IL-6 was related to maternal weight among the maternal characteristics, (R(2)=0.0679, p=0.01). IL-6 was increased (p=0.001) in the GDM group (median=2 pg/ml) compared to the control group (median=1.5 pg/ml) even after adjustment for maternal weight. IL-6 was inversely related to birth weight adjusted for gestational age at delivery (r=-0.3382, p<0.001) and glucose levels at oral glucose test. Maternal weight and age were the only predictors of GDM among the maternal characteristics [Detection Rate (DR)=59.4%; for 25% False Positive Rate (FPR); Area Under the Curve (AUC)=0.7291; Model R(2)=0.1096, p<0.001]. IL-6 alone was a significant predictor of GDM (DR=51.3%; for 25% FPR; AUC=0.6731; Model R(2)=0.0616, p<0.001). Combination of maternal characteristics with IL-6 yielded an improved prediction (DR=67.5%; for 25% FPR; AUC=0.7586; Model R(2)=0.1521, p<0.001). IL-6 concentrations are increased at 11-14 weeks in pregnancies with GDM. Combination of maternal characteristics and maternal serum IL-6 levels may provide effective first trimester screening for GDM.

Abstract
OBJECTIVE Intrauterine growth restriction (IUGR) has been associated with decreased supply of crucial substrates to the fetus and affects its growth and development by temporarily or permanently modifying gene expression and function. However, not all neonates born by calorie restricted mothers are IUGR and there are no reports regarding their brain protein expression vis-à-vis that of their IUGR siblings. Here, we investigated the expression of key proteins that regulate growth and development of the brain in non-IUGR newborn pups versus IUGR siblings and control pups. METHODS Rat brain proteins were isolated from each group upon delivery and separated by two-dimensional gel electrophoresis (2-DE). RESULTS 14-3-3 Protein, calreticulin, elongation factor, alpha-enolase, fascin, heat-shock protein HSP90 and pyruvate kinase isozymes were significantly increased (p < 0.05) in samples obtained from IUGR newborn pups compared to non-IUGR. Conversely, collapsin response mediator proteins, heat-shock70 and peroxiredoxin2 were decreased in IUGR group compared to non-IUGR. CONCLUSIONS In our experimental study, IUGR pups showed an altered proteomic profile compared to their non-IUGR siblings and non-IUGR controls. Thus, not all offspring of calorie-restricted mothers become IUGR with the accompanying alterations in the expression of proteins. The differentially expressed proteins could modulate alterations in the energy balance, plasticity and maturation of the brain.

Abstract
BACKGROUND Recent studies support that osteocalcin (OC), apart from its skeletal role, is implicated in glucose homoeostasis. Aims of this study were to examine the first-trimester maternal serum concentrations of OC in pregnancies that developed gestational diabetes mellitus (GDM) and to create a first-trimester prediction model for GDM. DESIGN Case-control study in a prospective cohort of pregnant women. Maternal serum levels of OC were measured in 40 cases that developed GDM and 94 unaffected controls. First-trimester biophysical parameters, biochemical indices, maternal-pregnancy characteristics, and OC concentrations were assessed in relation to GDM occurrence. RESULTS In the GDM group, first-trimester OC serum levels were increased compared to the control group (mean = 8·81 ng/mL, SD = 2·59 vs. mean = 7·34 ng/ml, SD = 3·04, P = 0·0058). Osteocalcin was independent of first-trimester biophysical and biochemical indices. Osteocalcin alone (OR = 1·21, CI: 1·02-1·43, P = 0·023) was a significant predictor of GDM [Model R(2) = 0·04, area under the curve (AUC) = 0·61, CI: 0·55-0·72, P < 0·001]. The combination of maternal and pregnancy characteristics with OC resulted in an improved prediction model for GDM (Model R(2) = 0·21, AUC = 0·80, CI: 0·71-0·88, P < 0·001). The combined model yields a sensitivity of 72·2% for 25% false-positive rate. CONCLUSIONS First-trimester maternal serum levels of OC are increased in GDM pregnancies. Osteocalcin combined with maternal and pregnancy characteristics provides an effective screening for GDM at 11-14 weeks.

Abstract
Objective: To examine the value of the cervical length (CL) measurement at 24-30 gestational weeks in the prediction of spontaneous preterm delivery (SPD) between 30 and 34 weeks (SPD34) and between 34 and 37 weeks (SPD37). Methods: We performed a prospective cross-sectional study. CL was measured once by transvaginal ultrasound examination between 24 and 30 weeks. Results: The study sample consisted of 1,180 low-risk singleton pregnancies. 10 women (0.85%) had a SPD34 and 60 (5.08%) had a SPD37. CL was shorter (p < 0.001) in the women who had a SPD34 (median 11 mm) compared to the women who delivered after 34 weeks (median 31 mm). CL was shorter (p < 0.001) in the women who had a SPD37 (median 22 mm) compared to the women who delivered after 37 weeks (median 31 mm). CL predicted SPD34 (OR = 0.837, R2 = 0.2768, AUC = 0.9406, p < 0.001) and SPD37 (OR = 0.907, R2 = 0.1085, AUC = 0.7584, p < 0.001). The model achieved a sensitivity of 70.0 and 38.3% for 10% false-positive rate for SPD34 and SPD37, respectively. Conclusions: CL after 24 weeks is significantly shorter in women destined to have a SPD. In low-risk singleton pregnancies CL performs very well in predicting SPD34 and adequately in predicting SPD37.

Abstract
AIM To investigate the value of the birth weight of the previous pregnancy (BW1) alone and combined with the third trimester ultrasonographically estimated fetal weight (EFW) and Doppler studies in the prediction of small (SGA) and large for gestational age (LGA) neonates in the index pregnancy (BW2). METHOD Some 1298 parous women with uncomplicated singleton pregnancies who had a third trimester ultrasound scan were considered as samples in this retrospective cohort study. Maternal and pregnancy characteristics, BW1, EFW, umbilical artery, and middle cerebral artery pulsatility indices were investigated as predictors of SGA and LGA. RESULTS BW1, maternal weight, mode of conception, and smoking status were associated with BW2 (R2=0.39) with BW1 being the strongest predictor (R2=0.37). The addition of EFW conferred significant improvement (R2=0.63), whereas the addition of the Doppler indices did not. The sensitivity of BW1 alone in the prediction of SGA was 75% for 25% screen positive rate and increased to 92% with the addition of EFW. The equivalent figures for LGA were 68% and 93%, respectively. CONCLUSIONS BW1 used as a continuous variable is predictive of growth deviations in the index pregnancy. Incorporating EFW enhanced the sensitivity for the detection of both conditions.

Abstract
The aim of the study was to examine interleukin-6 (IL-6) maternal serum concentration at 11 to 14 gestational weeks in normal pregnancies and pregnancies complicated by gestational diabetes mellitus (GDM) and to create first trimester prediction models for GDM. Case-control study conducted in a Fetal Medicine Unit. Study population included 40 GDM cases and 94 controls. Maternal characteristics, first trimester ultrasound markers, biochemical indices, and IL-6 levels were used for our analysis. IL-6 was related to maternal weight among the maternal characteristics, (R(2)=0.0679, p=0.01). IL-6 was increased (p=0.001) in the GDM group (median=2 pg/ml) compared to the control group (median=1.5 pg/ml) even after adjustment for maternal weight. IL-6 was inversely related to birth weight adjusted for gestational age at delivery (r=-0.3382, p<0.001) and glucose levels at oral glucose test. Maternal weight and age were the only predictors of GDM among the maternal characteristics [Detection Rate (DR)=59.4%; for 25% False Positive Rate (FPR); Area Under the Curve (AUC)=0.7291; Model R(2)=0.1096, p<0.001]. IL-6 alone was a significant predictor of GDM (DR=51.3%; for 25% FPR; AUC=0.6731; Model R(2)=0.0616, p<0.001). Combination of maternal characteristics with IL-6 yielded an improved prediction (DR=67.5%; for 25% FPR; AUC=0.7586; Model R(2)=0.1521, p<0.001). IL-6 concentrations are increased at 11-14 weeks in pregnancies with GDM. Combination of maternal characteristics and maternal serum IL-6 levels may provide effective first trimester screening for GDM.

Elevated placental growth factor concentrations at 11-14 weeks of gestation to predict gestational diabetes mellitus. Metabolism 2014; 63:1419-25. [PMID: 25173717 DOI: 10.1016/j.metabol.2014.07.016] [Citation(s) in RCA: 42] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2014] [Revised: 07/29/2014] [Accepted: 07/30/2014] [Indexed: 01/13/2023]
Abstract
OBJECTIVE To examine maternal serum concentrations of placental growth factor (PlGF) at 11-14 gestational weeks in pregnancies that developed gestational diabetes mellitus (GDM) and to create first trimester prediction models for GDM. METHODS Case control study including 40 GDM cases and 94 controls. PlGF, biophysical and biochemical markers and maternal-pregnancy characteristics were analyzed. RESULTS Log10 transformed PlGF (log10 PlGF) was not related to maternal factors. Log10 PlGF was increased (p=0.008) in the GDM group compared to the control group. Log10 PlGF was associated with fasting glucose levels (p=0.04) in the oral glucose tolerance test. Log10 PlGF had a strong relation with birth weight adjusted for gestational age in the control but not in the GDM group. Maternal weight and maternal age were the only predictors of GDM among the maternal factors [area under the curve (AUC)=0.73, p<0.001]. Log10 PlGF alone was a significant predictor of GDM (AUC=0.63, p<0.001). Combination of maternal weight, maternal age and log10 PlGF resulted in an improved prediction (DR=71.4%, for 25% FPR, AUC=0.78, Model R(2)=0.17, p<0.001). CONCLUSION At 11-14weeks in pregnancies that develop GDM, the maternal serum levels of PlGF are increased. Measurement of serum PlGF at 11-14weeks improves the performance of early screening for GDM provided by maternal factors alone.
