BACKGROUND: Fetal growth restriction (FGR) is an unclearly defined condition described as a fetal weight which is too low in relation to gestational age. It is recognized in 10-15% of singleton pregnancies and can lead to severe complications, including stillbirth. To reduce the adverse fetal and neonatal outcomes, many medical interventions are being introduced by obstetricians. These, like all medical procedures, may induce further complications, such as preterm labor and its consequences...

BACKGROUND: Delayed cord clamping is the standard of care in infants not requiring resuscitation; however effects of cord clamping strategies have not been evaluated systematically in small for gestational age (SGA) infants. The primary objective was to compare effects of delayed cord clamping (DCC) and early cord clamping (ECC) on serum ferritin at 3 months in SGA infants born at ≥35 weeks. The secondary objectives were to compare hematological parameters, clinical outcomes in neonatal period and growth at 3 months of age...

A rise in plasma triacylglycerol levels is a common physiological occurrence during late gestation and excess of glucocorticoids (GCs) has been shown to impair lipid metabolism. Based on those observations, we investigated whether the administration of dexamethasone during the late gestational period could exacerbate this pregnancy associated hypertriacylglycerolemia in rats. For this, female Wistar rats were treated with dexamethasone (0.2 mg/kg of body mass in the drinking water on days 14-19 of pregnancy; DP group) or equivalent days in the virgin rats (DV group)...

BACKGROUND: Ultrasound measures are valuable for epidemiologic studies of risk factors for growth restriction. Longitudinal measurements enable investigation of rates of change and identification of windows where growth is impacted more acutely. However, missing data can be problematic in these studies, limiting sample size, ability to characterise windows of vulnerability, and in some instances creating bias. We sought to compare a parametric linear mixed model (LMM) approach to multiple imputation in this setting with multiple imputation by chained equation (MICE) methodology...

BACKGROUND: Advanced maternal age (AMA) has been associated with negative pregnancy outcomes. Oxidative stress (OS) and defective placental dysfunction are contributing factors. This study determined the association between AMA and adverse pregnancy outcomes, OS biomarkers and angiogenic growth mediators (AGMs) in normal pregnancies. METHODS: This prospective cohort study conducted at the Obstetrics and Gynaecology (O&G) Department of the Komfo Anokye Teaching Hospital (KATH) finally included 175 normal pregnant women comprising, 58 AMA (35-45 years), 55 (30-34 years) and 62 optimal childbearing age (20-29 years)...

Newborns with intrauterine growth-restriction are at increased risk of mortality and life-long co-morbidities. Insulin-like growth factor-II (IGF2) deficiency in humans as well as in mice leads to intrauterine growth restriction and decreased neonatal glycogen stores. The present study aims to further characterize the metabolic and transcriptional consequences of Igf2 deficiency in the newborn. We found that, despite being born significantly smaller than their wild-type (Igf2+/+ ) littermates, brain size was preserved in Igf2 knockout (Igf2-/- ), consistent with nutritional deficiency...

The guilt by association (GBA) principle has been widely used to predict gene functions, and a network‑based approach may enhance the confidence and stability of the analysis compared with focusing on individual genes. Fetal growth restriction (FGR), is the second primary cause of perinatal mortality. Therefore, the present study aimed to predict the optimal gene functions for FGR using a network‑based GBA method. The method was comprised of four parts: Identification of differentially‑expressed genes (DEGs) between patients with FGR and normal controls based on gene expression data; construction of a co‑expression network (CEN) dependent on DEGs, using the Spearman correlation coefficient algorithm; collection of gene ontology (GO) data on the basis of a known confirmed database and DEGs; and prediction of optimal gene functions using the GBA algorithm, for which the area under the receiver operating characteristic curve (AUC) was obtained for each GO term...

Bilateral complete clefts represent the result of an incomplete fusion with all the morphologic components present. It is well known that patients with bilateral cleft lip and palate have typical characteristics such as insufficient medial face development with an orthodontic class III tendency, flat nose and short columella with abnormal nasolabial angle, bilateral oronasal fistulas, alterations in the number and position of the lateral incisors, and agenesis or supernumerary teeth. Successfully solving these cases, results in a difficult challenge and studies showing extended follow-up are not frequent...

There is a growing number of studies on the association between ambient air pollution and adverse pregnancy outcomes, but their results have been inconsistent. Consequently, a comprehensive review of this research area is needed. There was a wide variability in studied pregnancy outcomes, observed gestational windows of exposure, observed ambient air pollutants, applied exposure assessment methods and statistical analysis methods Gestational duration, preterm birth, (low) birth weight, and small for gestational age/intrauterine growth restriction were most commonly investigated pregnancy outcomes...

Aminoacyl-tRNA synthetases (ARSs) canonical function is to conjugate specific amino acids to cognate tRNA that are required for the first step of protein synthesis. Genetic mutations that cause dysfunction or absence of ARSs result in various neurodevelopmental disorders. The human phenylalanine-tRNA synthetase (PheRS) is a tetrameric protein made of two a subunits coded by FARSA gene and two b subunits coded by FARSB gene. We describe eight affected individuals from an extended family with a multisystemic recessive disease manifest as a significant growth restriction, brain calcifications, and interstitial lung disease...

Antenatal surveillance of fetal growth is an essential part of good maternity care, as lack of detection of fetal growth restriction is directly associated with stillbirth and perinatal morbidity. New algorithms and guidelines provide care pathways which rely on regular third trimester ultrasound biometry and plotting of estimated fetal weight in pregnancies considered to be at increased risk, and their implementation has increased pressures on ultrasound resources. Customised growth charts have improved the distinction between constitutional and pathological smallness and reduced unnecessary referrals...

Reported cases of distal 15q interstitial duplications are uncommon and do not result in a recognizable pattern of abnormalities. Some studies report prenatal overgrowth, while others describe growth retardation. We present molecular cytogenetic characterization of a 14 Mb interstitial duplication, encompassing 81 Online Mendelian Inheritance in Man (OMIM) genes, in a fetus with single umbilical artery and short limbs. We propose that growth restriction, previously described and present in our patient, may be due to duplication of a gene or genes contained in the 15q24 region...

Preeclampsia is associated with over-activation of the innate immune system in the placenta, in which toll-like receptor 4 (TLR4) plays an essential part. With their potent anti-inflammatory effects, statins have been suggested as potential prevention or treatment of preeclampsia, although evidence remains inadequate. Herewith, we investigated whether pravastatin could ameliorate preeclampsia-like phenotypes in a previously established lipopolysaccharide (LPS)-induced rat preeclampsia model, through targeting the TLR4/NF-κB pathway...

OBJECTIVE: Antibodies that recognize the phosphatidylserine/prothrombin complex (antiphosphatidylserine/ prothrombin antibodies; aPS/PT) might reveal enhanced thrombotic risk in patients with systemic lupus erythematosus. Little is known about their association with pregnancy complications in the antiphospholipid syndrome (APS). METHODS: We enrolled 55 patients with APS who were seeking pregnancy in 2 Italian hospitals. Antiphospholipid antibodies (aPL), including anticardiolipin antibodies, anti-β2 -glycoprotein I antibodies, lupus-like anticoagulant, and aPS/PT antibodies were assessed, and the patients were prospectively followed for 24 months...

Alazami syndrome (AS) (MIM# 615071) is an autosomal recessive microcephalic primordial dwarfism (PD) with recognizable facial features and severe intellectual disability due to depletion or loss of function variants in LARP7. To date, 15 patients with AS have been reported. Here we describe two consanguineous Algerian sisters with Alazami PD due to LARP7 homozygous pathogenic variants detected by whole exome sequencing. By comparing these two additional cases with those previously reported, we strengthen the key features of AS: severe growth restriction, severe intellectual disability and some distinguishing facial features such as broad nose, malar hypoplasia, wide mouth, full lips and abnormally set teeth...
