RESUMO

OBJECTIVES: Use of ultrasonography has been suggested as an accurate adjunct to clinical evaluation of fetal position and station during labor. There are no available reports concerning its actual use in delivery wards. The aim of this survey was to evaluate the current practice regarding the use of ultrasonography during labor. METHODS: A questionnaire was sent to members of the Italian Society of Ultrasound in Obstetrics and Gynecology employed in delivery wards. The qFeuestionnaire was made up of 22 questions evaluating participant characteristics and the current use of ultrasound in labor in their hospital of employment. The answers were grouped according to participant characteristics. RESULTS: A total of 200 participants replied. Ultrasound was considered useful before an operative vaginal delivery by 59.6 % of respondents, while 51.8 and 52.5 % considered it useful in the management of prolonged first and second stages of labor, respectively. The major indication for ultrasound use during labor was the assessment of fetal occiput position. The major difficulties in its application were the perceived lack of training and the complexity of the ultrasound equipment use. Participants that reported fewer difficulties were those employed in hospitals with a higher number of deliveries or having delivery units with more years of experience using ultrasound in labor, or those who had attended specific training courses. CONCLUSIONS: The results indicate that, despite the reported evidence of a higher accuracy of ultrasound compared to clinical evaluation in assessing fetal position and station, its use is still limited, even amongst maternal-fetal medicine practitioners specialized in ultrasonography.

RESUMO

INTRODUCTION: The myocardial performance index (MPI) has been proposed to evaluate cardiac dysfunction in newborns from diabetic mothers. Although MPI is routinely assessed in newborns, its role in the evaluation of fetuses from women with hyperglycemia in pregnancy (HIP) is still under evaluation. We aimed to evaluate the differences in third trimester fetal MPI in pregnant women with hyperglycemia compared to healthy controls. MATERIALS AND METHODS: Seven electronic databases were searched for all studies assessing women with HIP who underwent evaluation of fetal left MPI during pregnancy compared to a control group. The summary measures were reported as mean differences (MD) in the mean fetal left MPI between women with HIP and healthy controls, with a 95 % confidence interval (CI). A post hoc subgroup analysis based on the type of HIP - pregestational diabetes, GDM, or gestational impaired glucose tolerance (GIGT) - was performed as an additional analysis. RESULTS: 14 studies assessing 1326 fetuses (580 from women with HIP and 746 from controls) were included. Women with HIP had a significantly higher mean left fetal MPI compared to controls (MD 0.08; 95 %CI: 0.05 to 0.11; p < 0.00 001). Subgroup analysis according to the type of HIP concurred with the overall analysis for women with DM (MD 0.07; 95 %CI: 0.01 to 0.13; p = 0.02) and for women with GDM (MD 0.012; 95 %CI: 0.07 to 0.17; p < 0.00 001) but not for women with GIGT (MD -0.01, 95 % CI -0.28 to 0.27; p = 0.96). CONCLUSION: Fetal left MPI is increased in pregnancies with HIP appearing as a potential marker of cardiac dysfunction.

RESUMO

Postpartum hemorrhage (PPH) is the leading cause of death or severe morbidity for the mother after delivery. As a consequence healthcare staff working in the delivery room should be trained to perform a prompt diagnosis and adequate management of PPH. Uneventful outcome is induced correct identification of the underlying cause of hemorrhage. Ultrasound is a promising technique for the prompt diagnosis of PPH etiology. Indeed, it is easily available, with relatively low cost, not using ionizing radiation, and can be used in different settings including the labor room, the operating theater and at the bedside of an affected women. In order to be effective Obstetricians should have an adequate knowledge of postpartum ultrasonography. In this article, we will review the sonographic findings occurring in PPH, in the differential diagnosis of the underlying cause of hemorrhage, that include retained placenta, morbidly adherent placenta, rupture of the uterus uterine, vascular anomalies of the uterine arteries and uterine inversion. We will also provide an algorithm to manage PPH according to the ultrasonographic findings.

RESUMO

OBJECTIVE: Prenatal diagnosis of the Ectrodactyly-Ectodermal dysplasia-clefting (EEC) syndrome has been based upon the detection of ectrodactyly, in association with facial clefting and/or positive family history. Our aim is to describe other ultrasonographic features indicating the presuntive diagnosis, regardless of genetic diagnosis, especially in cases of negative family history. MATERIALS AND METHODS: A case report and a review of the literature was assessed. RESULTS: Our case report showed a singleton foetus "lobster claw" deformities of hands and feet. Paternal history revealed bilateral agenesia of two fingers. Through literature, 15 case reports of prenatal diagnosis of EEC syndrome were found, 14 of which were eligible for our systematic review. The 33% of cases (5/15) had a familiar history of EEC, thus, we found one case of consanguinity of parents. Anomalies EEC-related were recognized in the 40% of cases (6/15). An association with genitourinary anomalies was found in 30% (5/15) of them. CONCLUSIONS: A strong suspicion of final diagnosis of EEC may be done in the presence of ectrodactyly, facial clefting and urinary malformation especially in cases of negative family history. More attention should be given to a genetic counseling, especially to understand a possible relation to other genetic syndromes.

RESUMO

BACKGROUND: Neurotrophins, such as BDNF and NGF, are overexpressed in tumor cells in cervical cancer, and HIV infection is associated with the upregulation of neurotrophin expression. Therefore, we aimed to investigate whether BDNF and NGF are overexpressed in preneoplastic cervical disease from HIV-infected women. METHODS: Women with preneoplastic cervical lesions (cervical intraepithelial neoplasia grade 2 or 3) were prospectively enrolled and grouped according to their HIV status. Samples from Loop Electrosurgical Excision Procedure (LEEP) for suspected cervical cancer were obtained, and immunohistochemistry was performed to evaluate BDNF and NGF expression. RESULTS: We included in our analysis 12 HIV-infected patients who were matched with 23 HIV-negative patients as a control group. Immunohistochemistry analysis showed that BDNF expression was significantly higher in cervical preneoplastic lesions from HIV-positive women than in the lesions from the control group. In particular, BDNF was expressed in 8/12 HIV-positive patients and 7/23 HIV-negative patients (66.7% vs. 30.4%, χ2 = 4.227; p = 0.040). NGF expression was not significantly higher in cervical preneoplastic lesions from HIV-positive women compared with that in the lesions from the control group. In particular, NGF was expressed in 8/12 HIV-positive patients and in 12/23 HIV-negative patients (66.7% vs. 52.2% χ2 = 0.676; p = 0.411). Logistic regression analysis showed that the HIV status is an independent predictor of BDNF expression in pre-invasive preneoplastic cervical disease when considered alone (crude OR 4.6, 95% CI 0.027-20.347; p = 0.046) and when analyzed with other co-factors (adjusted OR 6.786, 95% CI 1.084-42.476; p = 0.041). CONCLUSIONS: In preneoplastic cervical disease, BDNF expression is higher in HIV-infected women than in non-infected controls, and this is independent of the clinical features of the patients and from the presence of the HPV-HR genotype. BDNF can play a key role as a link between the pathways by which HIV and HPV interact to accelerate cervical cancer progression and invasion. These data can be useful to better understand the role of neurotrophins in the cancerogenesis of cervical cancer and the possible therapeutic strategies to improve disease outcomes.

RESUMO

BACKGROUND: The COronaVIrus Disease 2019 (COVID-19) has spread in Italy since February 2020, inducing the government to call for lockdown of any activity, apart primary needs, during the months March-May 2020. During the lockdown, a reduction of admissions and hospitalizations for ischemic diseases was noticed. Purpose of this study was to observe if there has been the same reduction trend in Accident & Emergency (A&E) unit admissions also for obstetric-gynecological conditions. METHODS: Medical records and electronic clinical databases were searched for all patients who were admitted to the obstetric A&E department or hospitalized at the Gynecology and Obstetrics Unit of University hospital of Naples Federico II, during the quarter March-May in the years 2019 and 2020. The mean ± standard deviation (SD) of monthly admission to the obstetric A&E department and hospitalization of the year 2020 was compared with that of the year 2019, using the unpaired T test with α error set to 0.05 and 95% confidence intervals (95% CI). RESULTS: Admissions were 1483 in the year 2020 and 1786 in 2019. Of total, 1225 (37.5%) women were hospitalized: 583 in the year 2020, 642 in 2019. Mean ± SD of patients monthly admitted to our obstetric A&E department was 494 ± 33.7 in the year 2020, and 595.3 ± 30.9 in 2019, with a mean difference of - 101.3 (95% CI - 103.5 to - 99.1; p < 0.0001). Mean ± SD of patients monthly hospitalized to our department was 194 ± 19.1 in the year 2020, 213.7 ± 4.7 in 2019, with a mean difference of - 19.7 (95% CI - 23.8 to - 15.6; p < 0.0001). CONCLUSION: A significant decrease in the mean of monthly admissions and hospitalizations during the COVID-19 pandemic when compared to the previous year was found also for obstetric-gynecological conditions. Further studies are necessary to assess COVID-19 impact and to take the most appropriate countermeasures.

RESUMO

Regenerative medicine represents a growing hot topic in biomedical sciences, aiming at setting out novel therapeutic strategies to repair or regenerate damaged tissues and organs. For this perspective, human mesenchymal stem cells (hMSCs) play a key role in tissue regeneration, having the potential to differentiate into many cell types, including chondrocytes. Accordingly, in the last few years, researchers have focused on several in vitro strategies to optimize hMSC differentiation protocols, including those relying on epigenetic manipulations that, in turn, lead to the modulation of gene expression patterns. Therefore, in the present study, we investigated the role of the class II histone deacetylase (HDAC) inhibitor, MC1568, in the hMSCs-derived chondrogenesis. The hMSCs we used for this work were the hMSCs obtained from the amniotic fluid, given their greater differentiation capacity. Our preliminary data documented that MC1568 drove both the improvement and acceleration of hMSCs chondrogenic differentiation in vitro, since the differentiation process in MC1568-treated cells took place in about seven days, much less than that normally observed, namely 21 days. Collectively, these preliminary data might shed light on the validity of such a new differentiative protocol, in order to better assess the potential role of the epigenetic modulation in the process of the hypertrophic cartilage formation, which represents the starting point for endochondral ossification.

RESUMO

BACKGROUND: The clinical diagnosis of late Fetal Growth Restriction (FGR) involves the integration of Doppler ultrasound data and Fetal Heart Rate (FHR) monitoring through computer assisted computerized cardiotocography (cCTG). The aim of the study was to evaluate the diagnostic power of combined Doppler and cCTG parameters by contrasting late FGR -and healthy controls. METHODS: The study was conducted from January 2018 to May 2020. Only pregnant women who had the last Doppler measurement obtained within 1 week before delivery and cCTG performed within 24 h before delivery were included in the study. Two hundred forty-nine pregnant women fulfilling the inclusion criteria were enrolled in the study; 95 were confirmed as late FGR and 154 were included in the control group. RESULTS: Among the extracted cCTG parameters, Delta Index, Short Term Variability (STV), Long Term Variability (LTV), Acceleration and Deceleration Phase Rectified Slope (APRS, DPRS) values were lower in the late FGR participants compared to the control group. In the FGR cohort, Delta, STV, APRS, and DPRS were found different when stratifying by MCA_PI (MCA_PI <5th centile or > 5th centile). STV and DPRS were the only parameters to be found different when stratifying by (UA_PI >95th centile or UA_PI <95th centile). Additionally, we measured the predictive power of cCTG parameters toward the identification of associated Doppler measures using figures of merit extracted from ROC curves. The AUC of ROC curves were accurate for STV (0,70), Delta (0,68), APRS (0,65) and DPRS (0,71) when UA_PI values were > 95th centile while, the accuracy attributable to the prediction of MCA_PI was 0.76, 0.77, 0.73, and 0.76 for STV, Delta, APRS, and DPRS, respectively. An association of UA_PI>95th centile and MCA_PI<5th centile with higher risk for NICU admission, was observed, while CPR < 5th centile resulted not associated with any perinatal outcome. Values of STV, Delta, APRS, DPRS were significantly lower for FGR neonates admitted to NICU, compared with the uncomplicated FGR cohort. CONCLUSIONS: The results of this study show the contribution of advanced cCTG parameters and fetal Doppler to the identification of late FGR and the association of those parameters with the risk for NICU admission. TRIAL REGISTRATION: Retrospectively registered.

RESUMO

INTRODUCTION: The role of cerebroplacental ratio (CPR) or umbilicocerebral ratio (UCR) to predict adverse intrapartum and perinatal outcomes in pregnancies complicated by late fetal growth restriction (FGR) remains controversial. METHODS: This was a multicenter, retrospective cohort study involving 5 referral centers in Italy and Spain, including singleton pregnancies complicated by late FGR, as defined by Delphi consensus criteria, with a scan 1 week prior to delivery. The primary objective was to compare the diagnostic accuracy of the CPR and UCR for the prediction of a composite adverse outcome, defined as the presence of either an adverse intrapartum outcome (need for operative delivery/cesarean section for suspected fetal distress) or an adverse perinatal outcome (intrauterine death, Apgar score <7 at 5 min, arterial pH <7.1, base excess of >-11 mEq/mL, or neonatal intensive care unit admission). RESULTS: Median CPR absolute values (1.11 vs. 1.22, p = 0.018) and centiles (3 vs. 4, p = 0.028) were lower in pregnancies with a composite adverse outcome than in those without it. Median UCR absolute values (0.89 vs. 0.82, p = 0.018) and centiles (97 vs. 96, p = 0.028) were higher. However, the area under the curve, 95% confidence interval for predicting the composite adverse outcome showed a poor predictive value: 0.580 (0.512-0.646) for the raw absolute values of CPR and UCR, and 0.575 (0.507-0.642) for CPR and UCR centiles adjusted for gestational age. The use of dichotomized values (CPR <1, UCR >1 or CPR <5th centile, UCR >95th centile) did not improve the diagnostic accuracy. CONCLUSION: The CPR and UCR measured in the week prior delivery are of low predictive value to assess adverse intrapartum and perinatal outcomes in pregnancies with late FGR.

RESUMO

BACKGROUND: Despite the well-known second trimester ultrasound signs, current possibilities of in utero surgical repair of open spina bifida require a timely detection of the spine defect. OBJECTIVE: To evaluate the diagnostic accuracy of the ratio between brain stem (BS) diameter and its distance to the occipital bone (BSOB) (BS/BSOB ratio) in the detection of fetuses with open spina bifida at first trimester ultrasound. METHODS: A systematic review and meta-analysis of diagnostic accuracy was performed by searching seven electronic databases from their inception to February 2019 for all studies assessing the association between BS/BSOB ratio and diagnosis of spine bifida. Diagnostic accuracy of BS/BSOB ratio in prenatal diagnosis of spine bifida was assessed as sensitivity, specificity, positive and negative likelihood ratios (LR + and LR-), and area under the curve (AUC) on SROC curves. RESULTS: Four studies, including 17,598 fetuses with 23 cases of open spina bifida, were included in the meta-analysis. BS/BSOB ratio showed pooled sensitivity of 0.70 (95% CI 0.47-0.87; I2 = 78.3%), specificity of 1.00 (95% CI 0.99-1.0; I2 = 99.2%), LR + and LR- of 51.44 (95% CI 9.53-277.64; I2 = 85.5%) and 0.23 (95% CI 0.04-1.17; I2 = 64.8%), respectively, and an AUC of 0.9649. CONCLUSION: First trimester BS/BSOB ratio has a high diagnostic accuracy in detecting fetuses with open spina bifida.

RESUMO

INTRODUCTION: Sexual intercourse during pregnancy is commonly believed to trigger the onset of contractions and, therefore, labor. However, in low-risk pregnancies, there is neither association with preterm birth, premature rupture of membranes, or low birth weight, nor with spontaneous onset of labor at term. AIM: To evaluate the effectiveness of sexual intercourse for spontaneous onset of labor at term in singleton pregnancies. METHODS: The systematic search was conducted using electronic databases from inception of each database to June 2019. Review of articles also included the abstracts of all references retrieved from the search. Inclusion criteria were randomized controlled trials comparing sexual intercourse in singleton low-risk pregnancies at term with controls (either reduced number of coitus or no coitus) for spontaneous onset of labor. Estimates were pooled using random-effects meta-analysis. MAIN OUTCOME MEASURES: The primary outcome was the incidence of spontaneous onset of labor. The summary measures were reported as summary relative risk with 95% CI using the random-effects model of DerSimonian and Laird. RESULTS: Data extracted from 3 trials, including 1,483 women with singleton pregnancy at term and cephalic presentation, were analyzed. Women who were randomized in the sexual intercourse group had similar incidence of spontaneous onset of labor compared with control subjects (0.82% vs 0.80%; relative risk 1.02, 95% CI 0.98-1.07). CLINICAL IMPLICATION: Sexual intercourse should not be restricted in low-risk term pregnancies. Further studies are needed to properly evaluate the impact of orgasm, penetration, condom use, frequency of intercourse and other factors on induction of labor at term. STRENGTH & LIMITATIONS: Our study has several strengths. The three included trials had low risk of allocation bias; intention-to-treat analysis was used; this is the first meta-analysis on this issue so far. Limitations mainly depend on the design of the included studies. Firstly, compliance to the protocol relied on self-reporting by patients; in addition, not all the features of sexual intercourse could be adequately assessed (orgasm, nipple stimulation, sexual positions, etc.). CONCLUSION: In women with singleton, cephalic, low-risk pregnancies, sexual intercourse at term does not significantly increase the incidence of spontaneous onset of labor.

RESUMO

BACKGROUND: Antiphospholipid syndrome is an autoimmune, hypercoagulable state that is caused by antiphospholipid antibodies. Anticardiolipin antibodies, anti-ß2 glycoprotein-I, and lupus anticoagulant are the main autoantibodies found in antiphospholipid syndrome. Despite the amassed body of clinical knowledge, the risk of obstetric complications that are associated with specific antibody profile has not been well-established. OBJECTIVE: The purpose of this study was to assess the risk of obstetric complications in women with primary antiphospholipid syndrome that is associated with specific antibody profile. STUDY DESIGN: The Pregnancy In Women With Antiphospholipid Syndrome study is a multicenter, retrospective, cohort study. Diagnosis and classification of antiphospholipid syndrome were based on the 2006 International revised criteria. All women included in the study had at least 1 clinical criteria for antiphospholipid syndrome, were positive for at least 1 antiphospholipid antibody (anticardiolipin antibodies, anti-ß2 glycoprotein-I, and/or lupus anticoagulant), and were treated with low-dose aspirin and prophylactic low molecular weight heparin from the first trimester. Only singleton pregnancies with primary antiphospholipid syndrome were included. The primary outcome was live birth, defined as any delivery of a live infant after 22 weeks gestation. The secondary outcomes were preeclampsia with and without severe features, intrauterine growth restriction, and stillbirth. We planned to assess the outcomes that are associated with the various antibody profile (test result for lupus anticoagulant, anticardiolipin antibodies, and anti-ß2 glycoprotein-I). RESULTS: There were 750 singleton pregnancies with primary antiphospholipid syndrome in the study cohort: 54 (7.2%) were positive for lupus anticoagulant only; 458 (61.0%) were positive for anticardiolipin antibodies only; 128 (17.1%) were positive for anti-ß2 glycoprotein-I only; 90 (12.0%) were double positive and lupus anticoagulant negative, and 20 (2.7%) were triple positive. The incidence of live birth in each of these categories was 79.6%, 56.3%, 47.7%, 43.3%, and 30.0%, respectively. Compared with women with only 1 antibody positive test results, women with multiple antibody positive results had a significantly lower live birth rate (40.9% vs 56.6%; adjusted odds ratio, 0.71; 95% confidence interval, 0.51-0.90). Also, they were at increased risk of preeclampsia without (54.5% vs 34.8%; adjusted odds ratio, 1.56; 95% confidence interval, 1.22-1.95) and with severe features (22.7% vs 13.8%, adjusted odds ratio, 1.66; 95% confidence interval, 1.19-2.49), of intrauterine growth restriction (53.6% vs 40.8%; adjusted odds ratio, 2.31; 95% confidence interval, 1.17-2.61) and of stillbirth (36.4% vs 21.7%; adjusted odds ratio, 2.67; 95% confidence interval, 1.22-2.94). In women with only 1 positive test result, women with anti-ß2 glycoprotein-I positivity present alone had a significantly lower live birth rate (47.7% vs 56.3% vs 79.6%; P<.01) and a significantly higher incidence of preeclampsia without (47.7% vs 34.1% vs 11.1%; P<.01) and with severe features (17.2% vs 14.4% vs 0%; P=.02), intrauterine growth restriction (48.4% vs 40.1% vs 25.9%; P<.01), and stillbirth (29.7% vs 21.2% vs 7.4%; P<.01) compared with women with anticardiolipin antibodies and with women with lupus anticoagulant present alone, respectively. In the group of women with >1 antibody positivity, triple-positive women had a lower live birth rate (30% vs 43.3%; adjusted odds ratio,0.69; 95% confidence interval, 0.22-0.91) and a higher incidence of intrauterine growth restriction (70.0% vs 50.0%; adjusted odds ratio,2.40; 95% confidence interval, 1.15-2.99) compared with double positive and lupus anticoagulant negative women. CONCLUSION: In singleton pregnancies with primary antiphospholipid syndrome, anticardiolipin antibody is the most common sole antiphospholipid antibody present, but anti-ß2 glycoprotein-I is the one associated with the lowest live birth rate and highest incidence of preeclampsia, intrauterine growth restriction, and stillbirth, compared with the presence of anticardiolipin antibodies or lupus anticoagulant alone. Women with primary antiphospholipid syndrome have an increased risk of obstetric complications and lower live birth rate when <1 antiphospholipid antibody is present. Despite therapy with low-dose aspirin and prophylactic low molecular weight heparin, the chance of a liveborn neonate is only 30% for triple-positive women.

RESUMO

OBJECTIVES: To evaluate the effectiveness of cervical pessary for preventing spontaneous preterm birth (SPTB) in singleton gestations with a second trimester short cervix. METHODS: Electronic databases were searched from their inception until February 2016. We included randomized clinical trials (RCTs) comparing the use of the cervical pessary with expectant management in singletons pregnancies with transvaginal ultrasound cervical length (TVU CL) ≤25 mm. The primary outcome was incidence of SPTB <34 weeks. The summary measures were reported as relative risk (RR) with 95% confidence interval (CI). RESULTS: Three RCTs (n = 1,420) were included. The mean gestational age (GA) at randomization was approximately 22 weeks. The Arabin pessary was used as intervention in all three trials, and was removed by vaginal examination at approximately 37 weeks. Cervical pessary was not associated with prevention of SPTB <37 (20.2% vs 50.2%; RR 0.50, 95% CI 0.23 to 1.09), <34, <32, and <28 weeks, compared to no pessary. No differences were found in the mean of GA at, interval from randomization to delivery, incidence of preterm premature rupture of membranes and of cesarean delivery, and in neonatal outcomes. The Arabin pessary was associated with a significantly higher risk of vaginal discharge. CONCLUSIONS: In singleton pregnancies with a TVU CL ≤25mm at 200 -246 weeks, the Arabin pessary does not reduce the rate of spontaneous preterm delivery or improve perinatal outcome. Individual patient data meta-analysis may clarify whether cervical pessary may be beneficial in subgroups, such as only singleton gestations without prior SPTB or by different CL cutoffs.

RESUMO

AIM: The aim of this study was to identify potential predictive factors for cervical disease in women with HIV and to evaluate adherence during follow-up to cervical cancer screening. METHODS: In order to identify the independent role of factors associated with the presence of a cervical abnormality, all of the variables showing in univariate analyses a potential association with the outcome variable (presence of cervical abnormalities) were entered into a multivariate logistic regression model, along with age at first visit to our center, and age at diagnosis. RESULTS: A total of 540 HIV-positive women who received screening for cervical cancer during the first year after their first visit to our center were included in the analysis; 423 (78.3%) had normal cytology and 117 (21.7%) had cytological abnormalities, classified as follows: 21 atypical squamous cells of undetermined significance (17.9%); 51 low-grade squamous intraepithelial lesions (43.6%); 41 high-grade squamous intraepithelial lesions (35.0%); and four cervical cancers (3.4%). In our study, women with more than two previous pregnancies were significantly associated with a lower risk of cervical cytological abnormalities compared to the other women. Women with CD4+ levels of 200-499/mm3 had a higher risk of developing cervical cytological abnormalities compared to those with a CD4+ level > 500/ mm3 . CONCLUSION: In summary, management of HIV-positive women must be modeled on HIV-clinical status, CD4+ cell count, drug regimen, and adherence to follow-up, relying on the cooperation of highly qualified professionals. In HIV-positive women, an adequate screening and follow-up allows for a reduced occurrence of advanced cervical disease and prevents recourse to invalidating surgical interventions.

RESUMO

This report describes a case of congenital toxoplasmosis in a newborn in Southern Italy. A pregnant mother had been admitted at the 20th week of her pregnancy on account of pharyngodynia and laterocervical lymphadenopathy. Although serological testing of the mother's serum documented a seroconversion with positive IgG and IgM anti-Toxoplasma antibodies during II trimester, the woman refused to perform prenatal diagnosis for congenital toxoplasmosis. Fetal ultrasound scan already showed mild asymmetrical triventricular hydrocephaly and cerebral calcifications. After birth, real-time PCR on cerebrospinal fluid and blood samples of the newborn showed a positive result for 529bp-repeat element DNA of T. gondii, In addition brain magnetic resonance imaging and computed tomography showed a characteristic diffuse brain tissue loss associated with hydrocephalus. For the first time molecular characterization of T. gondii isolate was performed directly from the newborn's CSF samples by using nested-PCR-RFLP of sag-2 and pk1 genes. The PCR-RLFP analysis revealed that the isolate belongs to the clonal type II, the predominant lineage causing human toxoplasmosis, as confirmed by DNA sequencing.

RESUMO

Importance: Spontaneous preterm birth is a major cause of perinatal morbidity and mortality. It is unclear if a cervical pessary can reduce the risk of spontaneous preterm delivery. Objective: To test whether in asymptomatic women with singleton pregnancies and no prior spontaneous preterm birth but with short cervical length on transvaginal ultrasound, use of a cervical pessary would reduce the rate of spontaneous preterm birth at less than 34 weeks of gestation. Design, Setting, and Participants: Parallel-group, nonblinded, randomized clinical trial conducted from March 1, 2016, to May 25, 2017, at a single center in Italy. Asymptomatic women with singleton gestations, no previous spontaneous preterm births, and cervical lengths of 25 mm or less at 18 weeks 0 days to 23 weeks 6 days of gestation were eligible. Interventions: Patients were randomized 1:1 to receive either cervical pessary (n = 150) or no pessary (n = 150). The pessary was removed between 37 weeks 0 days and 37 weeks 6 days of gestation or earlier if clinically indicated. The control group received standard care. For cervical length of 20 mm or shorter, women in both groups were prescribed vaginal progesterone, 200 mg/d, until 36 weeks 6 days of gestation. No bed rest or activity restriction was recommended. Main Outcomes and Measures: The primary end point was spontaneous preterm birth at less than 34 weeks of gestation. Secondary outcomes were adverse events. Results: Among 300 women who were randomized (mean age, 29 [SD, 6.3] years; mean gestational age, 22 [SD, 1.3] weeks), 100% completed the trial. The primary end point occurred in 11 women (7.3%) in the pessary group and 23 women (15.3%) in the control group (between-group difference, -8.0% [95% CI, -15.7% to -0.4]; relative risk, 0.48 [95% CI, 0.24-0.95]). During follow-up, the pessary group had a higher rate of increased or new vaginal discharge (86.7% vs 46.0%; between-group difference, +40.7% [95% CI, +30.1%-+50.3%]; relative risk, 1.88 [95% CI, 1.57-2.27]). Conclusions and Relevance: Among women without prior spontaneous preterm birth who had asymptomatic singleton pregnancies and short transvaginal cervical length, use of a cervical pessary, compared with no pessary use, resulted in a lower rate of spontaneous preterm birth at less than 34 weeks of gestation. The results of this single-center, nonblinded study among selected pregnant women require confirmation in multicenter clinical trials. Trial Registration: clinicaltrials.gov Identifier: NCT02716909.

RESUMO

OBJECTIVES: The aim of our study was to assess whether there is a relationship between maternal body mass index (BMI) and umbilical artery Doppler velocimetry in physiologic pregnancies. METHODS: Healthy pregnancy women, referred to our center at or before 32 weeks of gestation, were recruited. According to BMI, they were divided into underweight (BMI < 18.5), normal weight (BMI 18.5-24.9), overweight (BMI 25.0-29.9) and obese women (BMI ≥ 30). At 32(+0) weeks of gestation, maternal BMI and umbilical artery Doppler velocimetry were recorded. A correlation between pulsatility index of umbilical artery and BMI was assessed by one-way ANOVA test, multiple comparison test (Bonferroni correction) and polynomial regression. RESULTS: One hundred eighty-five women were included. Mean pulsatility index of umbilical artery at 32(+0) was significantly higher in obese women (0.95 ± 0.01 vs 0.87 ± 0.01 vs 0.67 ± 0.01; p < 0.05). We found a positive correlation between Pulsatility Index of Umbilical Artery and maternal BMI (r(2) = 0.7; p < 0.05). CONCLUSION: There is a positive correlation between BMI and pulsatility index of umbilical artery. These findings suggest that obesity has a negative effect on feto-placetal vessels. If our data will be confirmed, maternal BMI should be considered in evaluation of umbilical Doppler velocimetry.

RESUMO

BACKGROUND: This study aims to evaluate maternal reassurance, satisfaction, and anxiety after two different strategies for the first-trimester screening for aneuploidies. METHODS: Patients between 11 + 3 and 13 + 6 weeks of gestation attending the first-trimester screening at Department of Mother and Child, University Hospital Federico II, Naples, Italy have been recruited and randomly allocated to contingent screening or universal cell-free fetal DNA testing (cffDNA). Questionnaires to measure reassurance, satisfaction, and anxiety have been filled twice: (Q1) after randomization and (Q2) after receiving results. Anxiety was measured by an Italian-version short form of the state scale of the Spielberger State-Trait Anxiety Inventory (STAI); child-related anxiety was measured by the 11-item Pregnancy-Related Anxiety Questionnaire-Revised Regardless of Parity (PRAQ-R2 scale); fear of bearing a physically or mentally handicapped child was measured considering only four items (item 4, 9, 10, and 11) of the PRAQ-R2 scale. RESULTS: 431 patients were recruited: 205 (49%) were randomized in the contingent screening arm, 226 (51%) in the cfDNA arm. Maternal reassurance, satisfaction, and anxiety were not different in the two groups. CONCLUSION: A contingent screening for aneuploidies in the first trimester seems able to ensure the same maternal reassurance and satisfaction as a cfDNA analysis in the low-risk population and to not affect maternal anxiety.

RESUMO

This scoping review synthesizes evidence on metformin's use during pregnancy, encompassing diverse conditions like gestational diabetes, type 1 and type 2 diabetes, polycystic ovary syndrome (PCOS), and obesity. Metformin demonstrates comparable efficacy to insulin in gestational diabetes, positive outcomes in type 2 diabetes pregnancies, and potential benefits in reducing complications. The review highlights nuances in its effects across conditions, indicating advantages such as reduced risk of macrosomia and cesarean section in gestational diabetes. However, its prophylactic role in preventing gestational diabetes and associated complications remains inconclusive. In obese pregnant women, mixed results are observed, with potential benefits in reducing pre-eclampsia risk. Metformin shows promise in preventing preterm birth and late miscarriage in PCOS pregnancies. Categorizing patient subgroups is crucial for identifying advantages, especially in gestational diabetes and type 2 diabetes. Challenges arise from study heterogeneity, necessitating standardized indications for dosage, timing, and postpartum follow ups. Efforts to identify patient characteristics influencing metformin efficacy are crucial for tailored therapy. Although metformin emerges as a viable option in complicated pregnancies, comprehensive research, standardized protocols, and subgroup identification efforts will enhance clinical utility, ensuring evidence-based therapies and optimal maternal and fetal outcomes. Bridging existing knowledge gaps remains imperative for advancing metformin's role in pregnancy management.
