RESUMO

OBJECTIVES: The management for improving maternal and neonatal outcomes of women with gestational diabetes mellitus (GDM) arriving at the delivery ward with pre-labour rupture of membranes (PROM) has not been elucidated. We tested the hypothesis that prolonged PROM in women with GDM would result in higher rates of neonatal hypoglycemia. METHODS: We retrospectively enrolled women with diet or insulin-controlled GDM who presented with spontaneous clear PROM. Each woman was allocated into one of two groups based on the PROM-delivery time: <18 hours (group 1) and ≥18 hours (group 2). The primary outcome was the incidence of neonatal hypoglycemia, defined as glucose <40 mg/dL (2.2 mmol/L) within 24 hours of birth. RESULTS: We ultimately analyzed 631 cases of GDM (6.7%), 371 with PROM-delivery <18 hours, and 260 with PROM-delivery ≥18 hours. The incidence of neonatal hypoglycemia did not differ between the two groups, reaching 7.3%. Women in group 2 were at increased risk of both cesarean delivery (20% vs. 12.4%, P < 0.01) and maternal chorioamnionitis morbidity (6.5% vs. 1.3%, P < 0.001). CONCLUSIONS: In a sub-group of women with GDM, a PROM-delivery time ≥18 hours is not associated with higher rates of neonatal hypoglycemia, but higher rates of chorioamnionitis and cesarean delivery were noted. Therefore, we suggest consideration for early delivery when managing women with GDM and PROM.

RESUMO

OBJECTIVES: Perinatal hypoxia causes premature activation and initiation of growth in dormant follicles, leading to diminished ovarian reserve. An indirect mechanism such as the release of stress-related hormones, may influence ovarian follicle recruitment under hypoxic conditions. We wanted to determine whether hypoxic ovarian damage results from increased follicle growth and "burnout" or from increased apoptosis, and whether this damage is age-dependent. DESIGN: Animal study Participants/Materials, Setting, Methods: Using adult 6-week-old (n=8) and one-day-old newborn (n=20) ICR (CD-1) female mice, ovarian follicular counts were conducted on H&E-stained sections. METHODS: Immunohistochemistry was performed on sections stained with Ki-67, anti-Caspase 3 and anti-FOXO3A. RESULTS: Exposure to hypoxia resulted in significantly reduced proportion of primordial follicles vs normoxia in both adult dams and newborn pups (3.17±2.75% vs. 17.89±4.4%; p=0.004; 40.59±14.88% vs. 81.92±31.56%, p=0.001, respectively), concomitant with increased growing- primary and secondary follicles, and more pronounced in adult dams vs newborn pups (6-fold vs. 2-fold, respectively). Ki67 staining revealed higher scores of cell proliferation in follicular granulosa cells after exposure to hypoxia than normoxia. However, Caspase 3 and Foxo3A staining did not show any differences in these markers of apoptosis in oocytes, granulosa cells, theca cells, or stromal cells when exposed to hypoxia versus normoxia. LIMITATIONS: The current study has several limitations; first, the sample size for each group is relatively small, which could limit the generalizability of the findings. Second, the study uses an ex vivo culture system, which may not fully capture the complex interactions that occur in the whole animal. Third, the exposure to hypoxia only lasted for 3 hours, which may not be long enough to observe all the potential effects. In addition, the study only analyzed specific markers of apoptosis in a few cell types, and other cell types or apoptotic pathways might be involved. Lastly, the study provides evidence for accelerated follicular activation and decreased ovarian reserve, but the underlying mechanisms are not fully explored. Conclusions Direct tissue hypoxia led to premature activation and initiation of growth in dormant follicles leading to diminished ovarian reserve. Hypoxic damage is age-dependent, with adult ovaries more susceptible than newborn ovaries. These findings support the possibility of follicular "burn out" as a potential mechanism responsible for hypoxia-induced loss of ovarian reserve.

RESUMO

The effects of MgSO4 as an anti-inflammatory agent in pregnant women have been investigated in the last few years. Infections can cause an inflammatory reaction involving the placenta membranes and amniotic cavity. They may have short-term effects on the mother and her fetuses, like preterm birth, cerebral palsy, and developmental delay. Despite the alleged advantages of MgSO4 as a neuroprotective agent in the preterm brain, the long-term molecular and behavioral function of MgSO4 has not been fully elucidated. Here, we investigated the long-term effect of antenatal MgSO4 , during late gestation, on offspring's behavior focusing on cognitive function, motor activity, and social cognition in adolescence and adulthood, and explored its influence on brain gene expression (e.g., ErbB signaling, pro-inflammatory, and dopaminergic markers) in adulthood. A significant abnormal exploratory behavior of offspring of MgSO4 -treated dams was found compared to the control group in both adolescence and adulthood. Furthermore, we found that adult females exposed to MgSO4 under inflammation displayed working and recognition memory impairment. A reduction in IL-6 expression was detected in the prefrontal cortex, and hippocampus specimens derived from LPS-Mg-treated group. In contrast, an imbalanced expression of dopamine 1 and 2 receptors was detected only in prefrontal cortex specimens. Besides, we found that MgSO4 ameliorated the overexpression of the Nrg1 and Erbb4 receptors induced by LPS in the hippocampus. Thus, MgSO4 treatment for preventing brain injuries can adversely affect offspring cognition behavior later in life, depending on the sex and age of the offspring.

RESUMO

OBJECTIVE: In the absence of safety data in humans, the use of cannabidiol (CBD) is not recommended during pregnancy. Yet >50% of pregnancies in women with epilepsy are unintended, making fetal exposure to CBD possible. As a small-molecule, highly lipid-soluble drug, CBD is likely to be distributed into the placenta and cross it. To estimate the placental distribution profile of CBD and its potential short-term placental effects, we conducted an ex vivo perfusion study in human placentas. METHODS: Placentas were obtained from healthy women undergoing cesarean deliveries. Selected cotyledons were cannulated and perfused for 180 min with a CBD-containing medium (250 ng/mL, .796 µmol·L-1 ; representative of a low therapeutic concentration; n = 8). CBD concentrations were determined at 180 min in the medium and placental tissue using liquid chromatography-tandem mass spectrometry. A customized gene panel array was used to analyze the expression of selected genes in the perfused placental cotyledons as well as in placentas perfused with 1000 ng/mL CBD (3.18 µmol·L-1 ; high therapeutic concentration; n = 8) and in those exposed to the vehicle. RESULTS: CBD was sequestered in the placental tissue, exhibiting significant variability across samples (median = 5342 ng/g tissue, range = 1066-9351 ng/g tissue). CBD concentrations in the fetal compartment were one fifth of those measured in the maternal compartment (median = 59 ng/mL, range = 48-72 ng/mL vs. 280 = ng/mL, range = 159-388 ng/mL, respectively; p < .01). Placental gene expression was not significantly altered by CBD. SIGNIFICANCE: The placenta acts as a depot compartment for CBD, slowing down its distribution to the fetus. This phenomenon might yield flatter but prolonged fetal CBD levels in vivo. The attenuated transplacental CBD transfer does not imply that its use by pregnant women is safe for the fetus. Only pregnancy registries and neurocognitive assessments would establish the risk of being antenatally exposed to CBD.

RESUMO

BACKGROUND: Preterm birth poses one of the biggest challenge in modern obstetrics. Prediction of preterm birth has previously been based on patient history of preterm birth, short cervical length around midtrimester, and additional maternal risk factors. Little is known about cervical length and physiology during the postpartum period and any associations between postpartum cervical features and subsequent preterm birth. OBJECTIVE: This study aimed to determine the feasibility and utility of postpartum cervical length measurements in prediction of subsequent spontaneous preterm birth. STUDY DESIGN: This was a prospective cohort study in a single tertiary center, conducted during a 5-year period (2017-2021). We evaluated the mean postpartum cervical length in patients after both preterm birth and term deliveries at 4 time periods: 8, 24, and 48 hours, and 6 weeks postpartum, with follow-up in their subsequent pregnancies to evaluate gestational age at delivery. The mean postpartum cervical length in different populations stratified by gestational age at delivery was assessed in phase 1 of the study, and the gestational age at subsequent delivery was assessed in phase 2. RESULTS: A total of 1384 patients participated in phase 1. Mean postpartum cervical length was significantly shorter in the preterm birth (<34 weeks' gestation) group than in the term group at 8 hours (8.4±4.2 vs 22.3±3.5 mm; P<.0001), 24 hours (13.2±3.8 vs 33.2±3.1 mm; P<.0001), and 48 hours (17.9±4.4 vs 40.2±4.2 mm; P<.0001) postpartum. There was no significant difference in mean postpartum cervical length between the preterm birth group and the term group at 8, 24, and 48 hours postpartum. Cervical length was similar between the groups at 6 weeks postpartum. A total of 891 patients participated in phase 2. The area under the curve was higher for preterm birth screening based on a history of a short postpartum cervix alone than for a history of spontaneous preterm birth alone (0.66 [95% confidence interval, 0.63-0.69] vs 0.57 [95% confidence interval, 0.54-0.61]; P<.0001). Combining both a history of spontaneous preterm birth and a short postpartum cervix resulted in additional benefit, with an area under the curve of 0.74 (95% confidence interval, 0.73-0.84; P<.0001). CONCLUSION: Postpartum cervical length measurements may assist in detecting the group of patients at higher risk of subsequent spontaneous preterm birth. It may be beneficial to consider an increased follow-up regimen and earlier interventions in this group to reduce adverse perinatal outcomes.

RESUMO

Trigonocephaly was previously described prenatally in association with severe abnormalities, mostly observed after 18 weeks of gestation. We describe our experience with this finding in early pregnancy, between 14 and 17 weeks of gestation. Our series includes 18 cases of trigonocephaly with several etiologies; trisomy 18, de novo translocation, thanatophoric dysplasia, and open spina bifida without hydrocephalus. Two fetuses had no other significant abnormalities and a spontaneous normalization of the skull shape was observed on follow-up. Both had normal genetic testing and postnatal outcome. These two cases represent a new phenomenon of an isolated transient form with normal outcome.

RESUMO

PURPOSE: This study evaluated the association between timing and indication for previous cesarean section (C-section) and its association with postpartum risks for adverse maternal outcomes, primarily postpartum hemorrhage (PPH) in vaginal birth after cesarean (VBAC). METHODS: This retrospective case-control study examined women following term vaginal delivery in a university-affiliated medical center between 2008 and 2018. Postpartum complications were compared between women who had their first VBAC and a control group comprised of women who had vaginal delivery without prior C-section. Additional analysis was performed to evaluate the association between the timing of previous C-section and the severity of postpartum adverse outcomes. RESULTS: Of the women meeting the inclusion criteria (n = 2879), 1,455 had VBAC and 1,424 were in the control group. Overall, significant postpartum complications, primarily PPH, were observed in the VBAC group compared to controls. Women who underwent C-section during second-stage of labor experienced higher PPH rates and increased drop in hemoglobin levels compared to women who underwent C-section during the first stage of labor or an elective C-Sect. (4.3 ± 0.9 g/dL vs. 2.8 ± 1.1 g/dL vs. 2.4 ± 0.8, p = 0.033). Concomitant increased need for blood transfusion (8.1% vs. 3.5% vs. 2.9%, respectively, p < 0.0001) and uterine atony (12.6% vs. 6.2% vs. 4.4%, respectively, p = 0.009) were also observed. No significant differences were demonstrated in other postpartum adverse effects evaluated. CONCLUSION: VBAC is associated with higher rates of postpartum complications, primarily PPH. The risk is significantly increased in VBAC following a second stage cesarean section. This data should be taken into consideration in the management of laboring women after C-section.

RESUMO

INTRODUCTION: Preterm infants with necrotizing enterocolitis (NEC) are at increased risk of cerebral injury and neurodevelopmental dysfunction. N-acetyl-cysteine (NAC) is a known anti-inflammatory and antioxidant agent. Currently, there is no prophylactic treatment in clinical use to prevent NEC and its neurodevelopmental sequelae. We sought to determine whether brain inflammation/apoptosis accompanies NEC systemic inflammation, and whether it can be attenuated by maternal NAC treatment during pregnancy and/or in the neonatal period in a rat model. MATERIAL AND METHODS: An established NEC newborn model (hypoxia 5% O2 for 10 min and formula feeding thrice daily, beginning on day 1 for 4 days) was used in Sprague-Dawley rat pups (n = 32). An additional group of pups (n = 33) received NAC (300 mg/kg intraperitoneal thrice daily) in addition to NEC conditions (NEC-NAC). Control pups (n = 33) were nursed and remained with the dam in room air. Two additional groups included pups of dams treated once daily with NAC (300 mg/kg intravenous) in the last 3 days of pregnancy. After birth, pups were randomized into NAC-NEC (n = 33) with NEC conditions and NAC-NEC-NAC (n = 36) with additional postnatal NAC treatment. Pups were sacrificed on the fifth day of life. Pup serum interleukin (IL)-6 protein levels, and brain nuclear factor kappa B (NF-κB) p65, neuronal nitric oxide synthase (nNOS), Caspase 3, tumor necrosis factor alpha (TNF-α), IL-6 and IL-1ß protein levels were determined by ELISA, western blot and TUNEL staining, and the groups were compared using analysis of variance (ANOVA). RESULTS: NEC pups had significantly increased serum IL-6 levels compared with the control group as well as increased neuronal apoptosis and brain protein levels of NF-κB, nNOS, Caspase 3, TNF-α, IL-6 and IL-1ß compared with control. In all NAC treatment groups, levels of serum IL-6, neuronal apoptosis and brain NF-κB, nNOS, Caspase 3, TNF-α, IL-6 and IL-1ß protein levels were significantly reduced compared with the NEC group. The most pronounced decrease was demonstrated within the NAC-NEC-NAC group. CONCLUSIONS: NAC treatment can attenuate newborn inflammatory response syndrome and decrease offspring brain neuroapoptosis and inflammation in a rat model of NEC by inhibition of NF-κB, nNOS and Caspase 3 pathways.

RESUMO

INTRODUCTION: Our objective was to evaluate whether there is a relationship between the "time during the day" of maternal betamethasone administration between 24 and 34 weeks' gestation and the risk for neonatal hypoglycemia. MATERIAL AND METHODS: A retrospective study included cases between 2008 and 2018. Eligible cases were pregnant women with singleton pregnancies who received a single course of betamethasone between 24 and 34 weeks' gestation. Each woman was allocated into one of four pre-defined groups based on the time when intramuscular betamethasone was administered. Group 1 (23:00-04:59) represents the lowest daily natural corticosteroids' activity, group 2 (05:00-10:59) represents the peak daily natural corticosteroids' activity, whereas group 3 (11:00-16:59) and group 4 (17:00-22:59) present an intermediate natural state of steady corticosteroids' secretion and activity. The primary outcome of the study was the incidence of neonatal hypoglycemia (glucose level of less than 40 mg/dL). RESULTS: We have identified 868 women who received a single complete course of betamethasone, of which 353 women (40.7%) had a steroid treatment latency to delivery up to 14 days. The incidence of neonatal hypoglycemia was significantly higher in group 2 (39.5%, 30/76, p = 0.0063), compared to group 1, who had the lowest incidence of neonatal hypoglycemia (16.9%, 12/71), and to group 3 and group 4. CONCLUSIONS: The "time during the day" when betamethasone administered is important when considering the risk for neonatal hypoglycemia. The risk was significantly higher when betamethasone was administered during the peak time and significantly lower when administered at the nadir time of maternal endogenous corticosteroid activity.

RESUMO

PURPOSE: Our aims were to describe the feasibility of diagnosis of DAA in early pregnancy and to assess its prenatal prevalence, associated anomalies and outcome. MATERIALS AND METHODS: A retrospective cohort review of all DAA cases diagnosed by early prenatal transvaginal scans at 12-17 weeks of gestation between the years 2007-2018 was performed. Associated anomalies, genetic abnormalities and long-term postnatal outcome were evaluated. RESULTS: 12 cases of DAA were diagnosed by early prenatal transvaginal scans at a median of 15 (range: 12-17) weeks of gestation out of a total of 28 654 early scans preformed with a prevalence of at least 1:2378. Associated anomalies/genetic abnormalities were found in 5/12 (42 %) cases. The diagnosis was confirmed postnatally in all newborns. In two cases termination of pregnancy was performed. Four patients (40 %) were symptomatic. Six patients (60 %) underwent surgery due to symptoms or due to severe obstruction on imaging with resolution of symptoms in all except one patient. CONCLUSION: DAA can be readily diagnosed transvaginally even in the first trimester. Its prevalence is 1:2387. A search for associated anomalies and genetic abnormalities should be performed. If DAA is isolated, the prognosis with or without surgery is usually good.

RESUMO

Perinatal hypoxia is a major cause of infant brain damage, lifelong neurological disability, and infant mortality. N-Acetyl-Cysteine (NAC) is a powerful antioxidant that acts directly as a scavenger of free radicals. We hypothesized that maternal-antenatal and offspring-postnatal NAC can protect offspring brains from hypoxic brain damage.Sixty six newborn rats were randomized into four study groups. Group 1: Control (CON) received no hypoxic intervention. Group 2: Hypoxia (HYP)-received hypoxia protocol. Group 3: Hypoxia-NAC (HYP-NAC). received hypoxia protocol and treated with NAC following each hypoxia episode. Group 4: NAC Hypoxia (NAC-HYP) treated with NAC during pregnancy, pups subject to hypoxia protocol. Each group was evaluated for: neurological function (Righting reflex), serum proinflammatory IL-6 protein levels (ELISA), brain protein levels: NF-κB p65, neuronal nitric oxide synthase (nNOS), TNF-α, and IL-6 (Western blot) and neuronal apoptosis (histology evaluation with TUNEL stain). Hypoxia significantly increased pups brain protein levels compared to controls. NAC administration to dams or offspring demonstrated lower brain NF-κB p65, nNOS, TNF-α and IL-6 protein levels compared to hypoxia alone. Hypoxia significantly increased brain apoptosis as evidenced by higher grade of brain TUNEL reaction. NAC administration to dams or offspring significantly reduce this effect. Hypoxia induced acute sensorimotor dysfunction. NAC treatment to dams significantly attenuated hypoxia-induced acute sensorimotor dysfunction. Prophylactic NAC treatment of dams during pregnancy confers long-term protection to offspring with hypoxia associated brain injury, measured by several pathways of injury and correlated markers with pathology and behavior. This implies we may consider prophylactic NAC treatment for patients at risk for hypoxia during labor.

RESUMO

BACKGROUND: The World Health Organization classified coronavirus disease-19 (COVID-19) as a pandemic and recommends strict restrictions regarding most aspects of daily activities. OBJECTIVES: To evaluate whether the pandemic has changed the prenatal care and pregnancy outcome in pregnant women without COVID-19. METHODS: The authors conducted a cross-sectional study to describe changes in outpatient clinic visits and to compare the rates of cesarean and instrumental deliveries between two periods of time: March-April 2020 (during the COVID-19 outbreak) with March-April of the preceding year, 2019. RESULTS: During the COVID-19 outbreak, visits to obstetric triage, gynecologic triage, high-risk clinic, and ultrasound units decreased by 36.4%, 34.7%, 32.8%, and 18.1%, respectively. The medical center experienced a 17.8% drop in the total number of births (610 births) compared with March and April 2019 (742 births). During the outbreak women were more likely to be nulliparous (33.3% vs. 27.6%, P = 0.02) and present with hypertensive disorders during pregnancy (7.5% vs. 4%, P = 0.005) or gestational diabetes (13% vs. 10%, P = 0.03). More epidural analgesia was used (83.1% vs. 77.1%, P = 0.006). There were more operative vaginal deliveries during the outbreak (16.7% vs. 6.8%, P = 0.01). All other maternal and neonatal outcomes were comparable between the two periods. CONCLUSIONS: The medical facility experienced a major decline in all aspects of the routine obstetrics activities during the time of the pandemic. The higher rate of operative vaginal deliveries among nulliparous may be associated with the pandemic effect on the rate of high-risk patients.

RESUMO

BACKGROUND: A low rate of primary cesarean delivery is expected to reduce some of the major complications that are associated with a repeat cesarean delivery, such as uterine rupture, adhesive placental disorders, hysterectomy, and even maternal death. Since 2014, and in alignment with the American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine, we changed our approach to labor dystocia, defined as abnormal progression of labor, by allowing a longer duration of the second stage of labor. OBJECTIVE: To examine the effect of prolonging the second stage of labor on the rate of cesarean delivery, and maternal and neonatal outcomes. MATERIALS AND METHODS: In a historical control group, we compared maternal and neonatal outcomes over 2 periods. Period I (9300 patients): from May 2011 until April 2014, when a prolonged second stage in nulliparous women was considered after 3 hours with regional anesthesia or 2 hours if no such anesthesia was provided. Second-stage arrest was defined in multiparous women after 2 hours with regional anesthesia or 1 hour without it. Period II (10,531 patients): from May 2014 until April 2017, allowed nulliparous and multiparous women continuing the second stage of labor an additional 1 hour before diagnosing second-stage arrest. Singleton deliveries at or beyond 37 weeks' gestation were initially considered for eligibility. We excluded women with high-risk pregnancies and known fetal anomalies. For comparing means, we used the t test. If variables were not normally distributed, we used the Mann-Whitney test instead. For comparing proportions, we used the χ2 test with continuity correction. RESULTS: The primary cesarean delivery was decreased in nulliparous women from 23.3% (819 of 3515) in period I to 15.7% (596 of 3796) in period II (relative risk [RR], 0.67; 95% CI, 0.61-0.74), a trend that was also significant in multiparous women (10.9%, 623 of 5785, in period I vs 8.1%, 544 of 6735, in period II; RR, 0.75; 95% CI, 0.67-0.84). The rate of operative vaginal deliveries in nulliparous women was higher in period II than in period I (19.2%, 732 of 3515, vs 17.7%, 622 of 3796, P < .0001). Rates of third- and fourth-degree laceration and of shoulder dystocia were also higher in period II. The rate of arterial cord pH < 7.0 and the rate of admission to the neonatal intensive care unit were higher in period II, but the early neurological outcome was not different when comparing the 2 periods. CONCLUSION: The new policy of labor management successfully decreased primary cesarean deliveries, with a small rise in instrumental deliveries. However, it also increased the other immediate maternal and neonatal complications. A higher rate of lower umbilical artery cord pH was the most significant finding; however, the early neurological outcome did not change. It is possible that the ongoing adjustment to the new labor protocol will avoid, in the future, maternal and neonatal complications. The long-term maternal and neonatal consequences of our new approach will be evaluated in future studies.

RESUMO

Advanced fetal sonographic equipment has contributed to the increase in prenatal diagnosis of congenital thoracic malformations. Among these anomalies is congenital lobar emphysema (CLE), a rare congenital anomaly characterized by over distention and overexpansion of the involved fetal pulmonary lobe. Several studies addressed the prenatal diagnosis of CLE in mid second or early third trimester. The early prenatal diagnosis and the outcome of a case of CLE are reported in this study.

RESUMO

BACKGROUND: Unilateral renal agenesis is a rare finding. There are no large-scale studies reporting this finding in early pregnancy. OBJECTIVES: To evaluate the incidence of unilateral renal agenesis (URA) and of associated anomalies diagnosed by early prenatal trans-vaginal sonography. METHODS: We performed a retrospective chart review of all 59,382 trans-vaginal scans performed at 14-16 weeks gestation by a single operator at different clinics during the period 1994-2013. RESULTS: The incidence of URA was 1:1212 (49/59382 cases). Associated anomalies were diagnosed in 22 cases (45%). Renal anomalies were diagnosed in 22.4%. Extra-renal anomalies (with exclusion of a single umbilical artery or nuchal edema as isolated findings) were diagnosed in 24.5%. Ambiguous genitalia were diagnosed in 8.2%. CONCLUSIONS: URA is a rare finding in early trans-vaginal sonography. Associated anomalies are very common and should be sought.

RESUMO

BACKGROUND: Maternal inflammation is a risk factor for neonatal brain injury and future neurological deficits. Pomegranates have been shown to exhibit anti-inflammatory, anti-apoptotic and anti-oxidant activities. OBJECTIVE: We hypothesized that pomegranate juice (POM) may attenuate fetal brain injury in a rat model of maternal inflammation. STUDY DESIGN: Pregnant rats (24 total) were randomized for intraperitoneal lipopolysaccharide (100 µg/kg) or saline at time 0 at 18 days of gestation. From day 11 of gestation, 12 dams were provided ad libitum access to drinking water, and 12 dams were provided ad libitum access to drinking water with pomegranate juice (5 mL per day), resulting in 4 groups of 6 dams (saline/saline, pomegranate juice/saline, saline/lipopolysaccharide, pomegranate juice/lipopolysaccharide). All dams were sacrificed 4 hours following the injection and maternal blood and fetal brains were collected from the 4 treatment groups. Maternal interleukin-6 serum levels and fetal brain caspase 3 active form, nuclear factor-κB p65, neuronal nitric oxide synthase (phosphoneuronal nitric oxide synthase), and proinflammatory cytokine levels were determined by enzyme-linked immunosorbent assay and Western blot. RESULTS: Maternal lipopolysaccharide significantly increased maternal serum interleukin-6 levels (6039 ± 1039 vs 66 ± 46 pg/mL; P < .05) and fetal brain caspase 3 active form, nuclear factor-κB p65, phosphoneuronal nitric oxide synthase, and the proinflammatory cytokines compared to the control group (caspase 3 active form 0.26 ± 0.01 vs 0.20 ± 0.01 U; nuclear factor-κB p65 0.24 ± 0.01 vs 0.1 ± 0.01 U; phosphoneuronal nitric oxide synthase 0.23 ± 0.01 vs 0.11 ± 0.01 U; interleukin-6 0.25 ± 0.01 vs 0.09 ± 0.01 U; tumor necrosis factor-α 0.26 ± 0.01 vs 0.12 ± 0.01 U; chemokine (C-C motif) ligand 2 0.23 ± 0.01 vs 0.1 ± 0.01 U). Maternal supplementation of pomegranate juice to lipopolysaccharide-exposed dams (pomegranate juice/lipopolysaccharide) significantly reduced maternal serum interleukin-6 levels (3059 ± 1121 pg/mL, fetal brain: caspase 3 active form (0.2 ± 0.01 U), nuclear factor-κB p65 (0.22 ± 0.01 U), phosphoneuronal nitric oxide synthase (0.19 ± 0.01 U) as well as the brain proinflammatory cytokines (interleukin-6, tumor necrosis factor-α and chemokine [C-C motif] ligand 2) compared to lipopolysaccharide group. CONCLUSION: Maternal pomegranate juice supplementation may attenuate maternal inflammation-induced fetal brain injury. Pomegranate juice neuroprotective effects might be secondary to the suppression of both the maternal inflammatory response and inhibition of fetal brain apoptosis, neuronal nitric oxide synthase, and nuclear factor-κB activation.

RESUMO

BACKGROUND: Ptyalism gravidarum (PG) is a condition of hypersalivation that affects pregnant women early in gestation. Symptoms include massive saliva volumes (up to 2 liters per day), swollen salivary glands, sleep deprivation, significant emotional distress, and social difficulties. OBJECTIVES: To examine maternal and fetal characteristics and pregnancy outcomes of patients with PG. METHODS: Patients diagnosed with PG in our clinic during the years 2001-2016 were identified and contacted. Demographic data were extracted from patient charts and clinical and outcome data was collected via telephone interviews. RESULTS: The incidence of PG was 1/963 (0.09%) in our sample. Eleven out of 22 women (40%) with PG were also diagnosed with hyperemesis gravidarum. Fetal gender did not increase the risk. Of the mothers presenting with PG, 37% had a positive family history for this condition. There was no associated increase in the rate of fetal or maternal complications. Two women reported a resolution of the symptoms immediately following hypnosis with acupuncture treatment. CONCLUSIONS: Although PG represents an unpleasant mental and physical condition, it does not pose any specific risk to the health of the mother or increase adverse perinatal outcomes for the fetus. Alternative medicine could play a role in the treatment of PG.

RESUMO

OBJECTIVES: 'Soft markers' (SMs) are nonspecific findings that might convey a higher risk for Down syndrome. We sought to determine the recurrence rate of the most common SM in subsequent pregnancies. METHODS: This is a retrospective study of all women who underwent early or late fetal sonographic anatomical screening in our ultrasound unit. The examined SMs were pyelectasis, thickened nuchal fold (TNF) and echogenic intracardiac foci (EIF). Data on recurrence and pregnancy outcome were retrieved retrospectively. RESULTS: The database included 20 672 singleton pregnancies; SMs were detected in 2347 (11.1%) of the fetuses and were isolated in 1739 (74%). Rates of solitary findings in the pregnancies were 6.5% (1360/20 672) EIF, 3% (624/18 850) TNF and 1.7% (363/20 672) pyelectasis. The recurrence rate of EIF, TNF and pyelectasis in subsequent consecutive pregnancies was 21%, 27% and 16%, respectively. Overall, 62 cases of Down syndrome were diagnosed in (1 : 333 pregnancies). No cases were diagnosed in patients with recurrent SMs. CONCLUSION: The high recurrence rate of solitary SM implies for genetic predisposition. These results might improve our counseling for pregnant women affected by the reappearance of solitary SM. Further studies are needed to assess the likelihood ratio for SM if recurrence occurs. © 2017 John Wiley & Sons, Ltd.

RESUMO

PURPOSE: Excess maternal inflammation and oxidative stress while in utero have been known to affect gross fetal development. However, an association between the inflammatory process in utero and the effects on ovarian development and future fertility has not yet been demonstrated. This study focused on LPS-induced chronic inflammation in early pregnancy and its effect on ovarian development and reserves of the offspring, using a rat model. Our aim was to determine whether maternal inflammation in utero disturbs reproductive system development in the offspring, given that maternal inflammation and oxidative stress has been shown to affect gross fetal development. METHODS: Prospective case control rat model. Sprague-Dawley pregnant rats (n = 11) received intraperitoneal lipopolysaccharide (LPS group) (50 µg/kg bodyweight) or saline solution (control group) on day 14, 16, and 18 of gestation. Pups were delivered spontaneously. At 3 months, female offspring were weighed and killed. Ovaries were harvested for (1) follicle count using hematoxylin and eosin staining, (2) apoptosis: ovaries were stained for caspase, and (3) serum CRP and AMH levels were determined. RESULTS: Birth weights of pups were significantly lower in the LPS group compared to the control group (6.0 ± 0.6 vs. 6.6 ± 0.4 gr; P = 0.0003). The LPS group had fewer preantral follicles, and increased intensity of Caspase 3 staining (510 vs. 155.5 u; P = 0.007). AMH levels were significantly lower in the LPS group (4.15 ± 0.46 vs 6.08 ± 1.88 ng/ml; P = 0.016). There was no significant difference in the CRP and MCP-1 levels between the two groups. CONCLUSIONS: Chronic maternal inflammation induced intrauterine growth restriction in offspring and a decrease in the proportion of follicles. This change might be due to premature apoptosis. These preliminary results suggest that maternal inflammation has a detrimental effect on the development of the female reproductive system of the offspring and thus, future fertility.
