Gestational diabetes, occurring during the hyperglycemic period of pregnancy in maternal life, is a pathologic state that increases the incidence of complications in both mother and fetus. Offspring thus exposed to an adverse fetal and early postnatal environment may manifest increased susceptibility to a number of chronic diseases later in life. Compelling evidence for the role of epigenetic transmission in these complications has come from comparison of siblings born before and after the development of maternal diabetes, exposure to this intrauterine diabetic environment being shown to cause alterations in fetal growth patterns which predispose these infants to developing overweight and obesity later in life. Diabetes of the offspring is also mainly the consequence of exposure to the diabetic intrauterine environment, in addition to genetic susceptibility. Since obesity and diabetes are known to increase the risk of cardiovascular disease, cardiovascular sequelae in the offspring of diabetic mothers are virtually inevitable. Research data also suggest that exposure to a diabetic intrauterine environment during pregnancy is associated with an increase in dyslipidemia, subclinical vascular inflammation, and endothelial dysfunction processes in the offspring, all of which are linked with development of cardiovascular disease later in life. The main underlying mechanisms involve persistent hyperglycemia hyperinsulinemia and leptin resistance.

considering that preterm birth accounts for about 6-10% of all births in Western countries and of more than 65% of all perinatal deaths, elucidation of the particularly complicated mechanisms of labor is essential for determination of appropriate and effective therapeutic interventions. Labor in humans results from a complex interplay of fetal and maternal factors, which act upon the uterus to trigger pathways leading gradually to a coordinated cervical ripening and myometrial contractility. Although the exact mechanism of labor still remains uncertain, several components have been identified and described in detail. Based on the major role played by the human placenta in pregnancy and the cascade of labor processes activated via placental mediators exerting endocrine, paracrine, and autocrine actions, this review article has aimed at presenting the role of these mediators in term and preterm labor and the molecular pathways of their actions. some of the aforementioned mediators are involved in myometrial activation and preparation and others in myometrial stimulation leading to delivery. In the early stages of pregnancy, myometrial molecules, like progesterone, nitric oxide, and relaxin, contribute to the retention of pregnancy. At late stages of gestation, fetal hypothalamus maturation signals act on the placenta causing the production of hormones, including crH, in an endocrine manner; the signals then enhance paracrinically the production of more hormones, such as estrogens and neuropeptides, that contribute to cervical ripening and uterine contractility. These molecules act directly on the myometrium through specific receptors, while cytokines and multiple growth factors are also produced, additionally contributing to labor.

Maternal postpartum vaccination against influenza was associated with a significant reduction of influenza-related morbidity, healthcare seeking, and antibiotic prescription in infants during the influenza season.

Fetal micrognathia involves abnormal or arrested development of the fetal mandible. Till recently, the prenatal diagnosis was subjective, based on the evaluation of the fetal profile and assessment of the relationship between the maxilla and the mandible. Recently objective sonographic methods have been utilized for diagnosing micrognathia such as the inferior facial angle, the jaw index, the frontal nasomental angle, the mandible width/maxilla width ratio and the mandibular length. Another useful sonographic sign, the mandibular gap in the retronasal triangle view, increases the accuracy of the diagnosis early in the first trimester. 3D sonographic views can add to the diagnosis and prenatal MRI is a useful adjunct to ultrasound in cases of limited acoustic window, maternal obesity, oligohydramnios and anterior spine position. The identification of micrognathia should prompt karyotyping and sonographic investigation for other abnormalities. The outcome of fetuses with this seemingly isolated finding is more guarded than one would intuitively believe, and the parents should be counseled accordingly. Postnatal complications including mild to severe upper airway obstruction leading to respiratory distress, feeding difficulties and mild to severe long-term developmental delay are common. One should be careful in pronouncing a fetus having 'micrognathia', especially on subjective evaluation, as this term implies that the fetus is abnormal with presence of significant pathology. There is no 'gold standard' for a definitive diagnosis of micrognathia on post-natal evaluation. Using a combination of objective sonographic markers as well as follow-up ultrasound assessments can significantly reduce the risk of a false diagnosis. Follow-up scans should be arranged, and neonatal service should be alerted in cases of ongoing pregnancies.Keywords Fetal mandible Á Micrognathia Á Retrognathia Á Inferior facial angle Á Frontal nasomental angle Á Jaw index Á Mandibular gap Á Chromosomal abnormalities Á Genetic syndromes Á Pierre Robin sequence

The development of the fetal nervous system mirrors general fetal development, comprising a combination of genetic resources and effects of the intrauterine environment. Our aim was to assess the 2nd trimester amniotic fluid levels of brain-derived neurotrophic factor (BDNF) and to investigate its association with fetal growth. In accordance with our study design, samples of amniotic fluid were collected from women who had undergone amniocentesis early in the 2nd trimester. All pregnancies were followed up until delivery and fetal growth patterns and birth weights were recorded, following which pregnancies were divided into three groups based on fetal weight: (1) AGA (appropriate for gestational age), (2) SGA (small for gestational age), and (3) LGA (large for gestational age). We focused on these three groups representing a reflection of the intrauterine growth spectrum. Our results revealed the presence of notably higher BDNF levels in the amniotic fluid of impaired growth fetuses by comparison with those of normal growth. Both SGA and macrosomic fetuses are characterized by notably higher amniotic fluid levels of BDNF (mean values of 36,300 pg/ml and 35,700 pg/ml, respectively) compared to normal-growth fetuses (mean value of 32,700 pg/ml). Though apparently small, this difference is, nevertheless, statistically significant (p value < 0.05) in SGA fetuses in the extremes of the distribution, i.e., below the 3rd centile. In conclusion, there is clear evidence that severe impairment of fetal growth induces the increased production of fetal brain growth factor as an adaptive mechanism in reaction to a hostile intrauterine environment, thereby accelerating fetal brain development and maturation.

Bisphenol A (BPA), a ubiquitous endocrine-disrupting chemical (EDC), is increasingly hypothesized to be a factor contributing to changes in fetal growth velocity. BPA exposure may be environmental, occupational, and/or dietary, with canned foods and plastic bottles contributing significantly. Our systematic review aims to evaluate the current literature and to investigate the role of BPA in abnormal fetal growth patterns. A search was conducted in the PubMed and Cochrane databases. A total of 25 articles met the eligibility criteria and were included in this systematic review. Eleven of them failed to show a clear relationship between BPA and abnormal fetal growth. The majority of the remaining studies (9/14) found an inverse association of BPA with indicators of fetal growth, whereas three studies suggested increased fetal growth, and two studies produced contradictory findings. Of note, both of the studies that collected a sample (amniotic fluid) directly reflecting BPA concentration in the fetus during the first half of pregnancy revealed an inverse association with birth weight. In conclusion, there is mounting evidence that combined exposure to BPA from dietary and non-dietary sources during pregnancy may contribute to abnormal fetal growth; a tendency towards fetal growth restriction was shown, especially when exposure occurs during the first half.

Background Real‐world data in patients with moderate psoriasis treated with apremilast is limited. Objectives To evaluate the effectiveness and safety of apremilast in bio‐naïve patients with moderate psoriasis in real‐world clinical settings. Methods This was a 52‐week multicenter, observational, prospective study of adult outpatients with moderate psoriasis {[10% < body surface area < 20% or 10 < psoriasis area severity index (PASI) < 20] and 10 < dermatology quality of life index (DLQI) < 20} initiated on apremilast ≤7 days before enrollment. Missing data were imputed using the last observation carried forward method. Results A total of 287 eligible patients (median age: 54.2 years; median psoriasis duration: 9.8 years) were consecutively enrolled. At baseline, the median DLQI and PASI scores were 12.0 and 11.8, respectively. The 52‐week DLQI ≤ 5 and PASI75 response rates were 68.3% and 61.0%. At 52 weeks, 70.8% and 72.7% of the patients shifted from moderate/severe/very severe to clear/minimal scalp and palmoplantar psoriasis involvement, respectively; the pruritus severity state improved in 67.2%. The 52‐week Kaplan–Meier estimated drug continuation rate was 85.3%. The adverse drug reaction rate was 19.9%. Conclusions Apremilast is a safe and effective treatment for bio‐naïve patients with moderate psoriasis and specific psoriasis manifestations.

Background Apremilast is an oral phosphodiesterase-4 inhibitor indicated for patients with moderate-to-severe chronic plaque psoriasis and active psoriatic arthritis.Objectives To examine the effectiveness of apremilast on Dermatology Life Quality Index (DLQI), Psoriasis Area and Severity Index (PASI) and nail, scalp and palmoplantar involvement, when administered prior to biologics.Methods This 52-week real-world study included biologic-naive adults with moderate psoriasis (psoriasis-involved body surface area 10% to <20%, or PASI 10 to <20 and DLQI 10 to <20). Apremilast was initiated ≤7 days before enrolment. Data from the first 100 eligible patients who completed 24 weeks (W24) of observation (or were prematurely withdrawn) are presented in this interim analysis using the last-observation-carried-forward imputation method. Results Eligible patients (mean age: 49.9 years; 71.0% males; median disease duration: 8.0 years) were consecutively enrolled between April and October 2017, by 18 dermatology specialists practising in hospital outpatient settings in Greece. Baseline DLQI (median: 12.0) and PASI (median: 11.7) scores improved (P < 0.001) at all postbaseline timepoints (Weeks 6, 16 and 24; W24 median decreases: 9.0 and 9.4 points respectively). At W24, DLQI ≤5, DLQI 0 or 1, and PASI-75 response rates were 63.0%, 25.0% and 48.0% respectively. The Nail Psoriasis Severity Index score in patients with baseline nail involvement (n = 57) decreased at all postbaseline timepoints (P < 0.001; W24 median decrease: 20.0 points). At W24, 50.0% and 51.7% of patients with baseline scalp (n = 76) and palmoplantar (n = 29) involvement respectively achieved postbaseline Physician's Global Assessment (PGA) score of 0 or 1 if baseline score was ≥3, or 0 if Clinicaltrials.gov number: NCT03059953
