Non-invasive cell-free DNA prenatal screening for trisomy 21 as part of primary screening strategy in twin pregnancy

OBJECTIVES

The performance of non-invasive prenatal screening using cell-free DNA testing of maternal blood in twin pregnancy is underevaluated, while serum marker-based strategies yield poor results. This study aimed to assess the performance of non-invasive prenatal screening for trisomy 21 in twin pregnancy as a first-tier test. Secondary objectives were to assess its failure rate and factors associated with failure.

METHODS

This retrospective cohort study included twin pregnancies in which non-invasive prenatal screening using cell-free DNA was performed as the primary screening strategy between May 2017 and October 2019. We used the NIPT VeriSeq® test for in-vitro diagnosis and set a fetal fraction cut-off of 4% for monochorionic pregnancies and 8% for dichorionic ones. Clinical data and pregnancy outcome were collected from physicians or midwives via a questionnaire or were retrieved directly on-site. We calculated the performance of non-invasive cell-free DNA screening for trisomy 21, analyzed its failure rate and assessed potentially associated factors.

RESULTS

Among 1885 twin pregnancies with follow-up, there were six (0.32%) confirmed cases of trisomy 21. The sensitivity of non-invasive prenatal screening for trisomy 21 was 100% (95% CI, 54.1-100%) and the false-positive rate was 0.23% (95% CI, 0.06-0.59%). The primary failure rate was 4.6%, with 4.0% being due to insufficient fetal fraction. A successful result was obtained for 65.4% of women who underwent a new blood draw, reducing the overall failure rate to 2.8%. Maternal body mass index, gestational age at screening as well as chorionicity were significantly associated with the risk of failure.

CONCLUSION

This study provides further evidence of the high performance, at an extremely low false-positive rate, of non-invasive prenatal screening in twins as part of a primary screening strategy for trisomy 21. © 2023 The Authors.

Clinical profiles of placenta accreta spectrum: the PACCRETA population-based study

OBJECTIVE

To describe and compare the characteristics of women with placenta accreta spectrum (PAS) and their pregnancy outcomes according to the presence of placenta praevia and a prior caesarean section.

DESIGN

Prospective population-based study.

SETTING

All 176 maternity hospitals of eight French regions.

POPULATION

Two hundred and forty-nine women with PAS, from a source population of 520 114 deliveries.

METHODS

Women with PAS were classified into two risk-profile groups, with or without the high-risk combination of placenta praevia (or an anterior low-lying placenta) and at least one prior caesarean. These two groups were described and compared.

MAIN OUTCOME MEASURES

Population-based incidence of PAS, characteristics of women, pregnancies, deliveries and pregnancy outcomes.

RESULTS

The PAS population-based incidence was 4.8/10 000 (95% CI 4.2-5.4/10 000). After exclusion of women lost to follow up from the analysis, the group with placenta praevia and a prior caesarean included 115 (48%) women and the group without this combination included 127 (52%). In the group with both factors, PAS was more often suspected antenatally (77% versus 17%; P < 0.001) and more often percreta (38% versus 5%; P < 0.001). This group also had more hysterectomies (53% versus 21%, P < 0.001) and higher rates of blood product transfusions, maternal complications, preterm births and neonatal intensive care unit admissions. Sensitivity analysis showed similar results after exclusion of women who delivered vaginally.

CONCLUSION

More than half the cases of PAS occurred in women without the combination of placenta praevia and a prior caesarean delivery, and these women had better maternal and neonatal outcomes. We cannot completely rule out that some of the women who delivered vaginally had placental retention rather than PAS; however, we found similar results among women who delivered by caesarean.

TWEETABLE ABSTRACT

Half the women with PAS do not have both placenta praevia and a prior caesarean delivery, and they have better maternal outcomes.

Initially untreated fasting hyperglycaemia in early pregnancy: prognosis according to occurrence of gestational diabetes mellitus after 22 weeks' gestation: a case-control study

AIMS

To evaluate the percentage of women with untreated fasting hyperglycaemia in early pregnancy who develop gestational diabetes mellitus after 22 weeks' gestation, the determinants of gestational diabetes development in such women and the prognosis of early fasting hyperglycaemia according to whether the women go on to develop gestational diabetes.

METHODS

From a large cohort of women who delivered in our hospital between 2012 and 2016, we retrospectively selected all those who had untreated early fasting hyperglycaemia and separated them into a 'gestational diabetes' and a 'no-gestational diabetes' group according to oral glucose tolerance test results after 22 weeks' gestation. We compared the incidence of a predefined composite outcome (preeclampsia or large-for-gestational-age infant or shoulder dystocia or neonatal hypoglycaemia) in both groups.

RESULTS

A total of 268 women (mean fasting plasma glucose 5.3 ± 0.3 mmol/l at a mean ± sd of 10.2 ± 4.2 weeks' gestation) were included. Gestational diabetes developed in 134 women and was independently associated with early fasting plasma glucose ≥ 5.5 mmol/l [odds ratio 3.16 (95% CI 1.57, 6.33)], age ≥ 30 years [odds ratio 2.78 (95% CI 1.46, 5.31)], preconception obesity [odds ratio 2.12 (95% CI 1.11, 4.02)], family history of diabetes [odds ratio 1.87 (95% CI 1.00, 3.50)] and current employment [odds ratio 0.46 (95% CI 0.26, 0.83)]. Despite treatment, gestational diabetes induced a significant increase in the composite outcome as compared to no gestational diabetes (odds ratio 2.16 [95% CI 1.08, 4.34]). The association disappeared after adjustment for risk factors.

CONCLUSIONS

Only half of the women with early fasting hyperglycaemia and no specific care subsequently developed gestational diabetes, and these women had a poor prognosis despite gestational diabetes treatment. Poor prognosis was mostly attributable to risk factors. Our results suggest that only women with certain risk factors should be screened for early fasting hyperglycaemia.

Predicting the likelihood of a live birth for women with endometriosis-related infertility

OBJECTIVE

Endometriosis affects 10% of women in reproductive age and alters fertility. Its management is still debated notably the timing of surgery and ART in infertility. Several tools have been created to guide the practitioner and the couple yet many limitations persist. The objective is to create a nomogram to predict the likelihood of a live birth after surgery followed by assisted reproductive technology (ART) for patients with endometriosis-related infertility.

STUDY DESIGN

All women in a public university hospital who attempted to conceive by ART after surgery for endometriosis-related infertility from 2004 to 2016 were included. We created a model using multivariable linear regression based on a retrospective database.

RESULT

Of the 297 women included, 171 (57.6%) obtained a live birth. Age, duration of infertility, number of ICSI-IVF cycles, ovarian reserve and the revised American Fertility Society (rAFS) score were included in the nomogram. The predictive model had an area under the curve (AUC) of 0.77 (95% CI, 0.75-0.79) and was well calibrated. The external validation of the model was achieved with an AUC of 0.71 (95% CI, 0.69-0.73) and calibration was good. The staging accuracy according to AUC criteria for the nomogram compared to the currently used Endometriosis Infertility Index to predict live births were 0.77 (95% CI, 0.75-0.79) and 0.60 (95% CI: 0.57-0.63), respectively.

CONCLUSION

This simple tool appears to accurately predict the likelihood of a live birth for a patient undergoing ART after surgery for endometriosis-related infertility. It could be used to counsel patients in their choice between spontaneous versus ART conception, or oocyte donation.

[Induction of labor in women with previous caesarean delivery with balloon catheter: Is it worth it?]

OBJECTIF

Balloon catheters for labor induction at term after previous cesarean section is an alternative option to iterative cesarean section. The aim of this study was to analyze the maternal and neonatal outcomes of the trial of labor after cesarean (TOLAC) in women with unfavorable cervix and balloon catheter induction, 2 years after introduction of this process.

METHODS

Unicentric observational study of women with term cephalic singleton, unfavorable cervix (simplified Bishop score<5) after TOLAC using double-balloon catheter. Were analyzed the mode of delivery and severe maternal (uterine rupture, post-partum hemorrhage, severe perineal tears) and neonatal (neonatal unit admission, APGAR<7 at 5minutes, pH<7.1) outcomes. Predictive factors for failed TOLAC were analyzed by using multivariate logistic regression.

RESULTS

Between 2016-2017, 455 (75.4%) women had TOLAC, whose 59 (13%) women with balloon catheter. The overall vaginal delivery (VD) was 73.9%. After Balloon catheter, the VD rate was 50.8%, versus 79.1% after spontaneous labor, and 68.2% after alone oxytocin/artificial membrane rupture induction (P<0.05). Previous VD (aOR 0.176 CI-95% [0.048-0.651]) and prior sweeping membrane (aOR 0.161 CI-95% [0.034-0.761]) was protective for cesarean section after TOLAC. Severe maternal and neonatal morbidities were observed in 10 (17%) and 8 (13.6%) cases, respectively.

CONCLUSION

Double-Balloon catheter is an option for unfavorable cervix and term induction after previous cesarean section. However, the TOLAC in women whose unfavorable cervix is not without maternal and neonatal risk, especially due to its failure.

Is episiotomy worthwile to prevent obstetric anal sphincter injury during operative vaginal delivery in nulliparous women?

OBJECTIVES

Episiotomy is a marker of Obstetric Anal Sphincter Injury (OASIS) condition, therefore, unmeasured factors could have biased the strength of the association between episiotomy and reduced OASIS during Operative Vaginal Delivery (OVD). The aim of this study was to compare the OASIS rate during OVD according to episiotomy practice.

STUDY DESIGN

Retrospective cohort study of all nulliparous pregnant women attempting an OVD between 2014-2017. To avoid unmeasured bias, all maternal and delivery data were prospectively captured after the birth. The strong relationship between parity and episiotomy practice (indication bias) lead to analyze only nulliparous women. Association between mediolateral episiotomy and OASIS following OVD was performing by using multivariate logistic regression analysis including significant variable in univariate analysis and relevant factors known to be associated both with OASIS and/or OVD.

RESULTS

Over the study period, 1709 (17.1%) women had an OVD, among them 40 (2.3%) had OASIS. In the 1342 (78.5%) nulliparous women, OASIS rate were 2% and 5.1% with and without episiotomy (p < 0.01). In multivariate analysis a lower incidence of OASIS with the use of episiotomy (OR 0.267 IC 0.132-0.541) were observed. The persistent occiput posterior position was associated with an increase risk of OASIS (OR 6.742 IC 2.376-19.124). Spatula/forceps, as compared to vacuum operative vaginal delivery increased the risk OASIS (OR 2.847 IC 1.311-7.168). Area under the curve of the model was 0.745.

CONCLUSION

Episiotomy is a modifiable risk factors which can contribute to reduce the risk of OASIS in nulliparous women with operative vaginal delivery. This intervention should be included in a global management of the second stage of labor.

Bartholin gland abscess during pregnancy: Report on 40 patients

OBJECTIVE(S)

To study the clinical and bacterial characteristic of Bartholin gland abscesses during pregnancy and the obstetric and neonatal outcomes.

STUDY DESIGN

Retrospective cohort study of all patients with surgical treatment of Bartholin gland abscesses between 2004 and 2015 in our university center. Clinical and bacterial characteristics between pregnant and non-pregnant women were compared.

RESULTS

During the period study, 156 patients were included (40 pregnant and 116 non pregnant). The incidence of Bartholin gland abscesses during pregnancy was 0.13%. Eight (20%) abscesses occurred in the first, 18 (45%) in the second, 11 (47.5%) in the third trimester and 3 (7.5%) in the post-partum course. No severe perineal and neonatal infections occurred during pregnancy. One late miscarriage and one preterm delivery were observed. We found more multiparity in the pregnant woman group than in non-pregnant women (62.5% versus 45%, p<0.05). A history of Bartholin gland abscesses were also more frequent in pregnant women (55% versus 30.1%, p<0.05). First line antibiotic therapy was more frequent in non-pregnant women (20% versus 45%, p<0.05). The rate of positive culture did not differ between the two groups (70% versus 55.2%). Among negative pus cultures, no patient in the pregnant woman group had received a first line antibiotic therapy, in contrast with non-pregnant women (0% versus 25%, p<0.05). E. coli was the most common pathogen in the two groups (48.9% of positive cultures and 28.2% of the overall population). The distribution of bacterial taxa was not different between the two groups.

CONCLUSION

Bacterial characteristics did not differ from non-pregnant women. Pregnancy could increase the occurrence of Bartholin gland abscesses in patients with previous surgical treatment of abscesses. When appropriate management is applied, maternal and neonatal outcomes are favorable, and severe infections are not to be expected.

[Cord accident after external cephalic version: Reality or mostly myth?]

OBJECTIVES

To study the occurrence of cords accident (nuchal cords, prolapse, and braces) after external cephalic version according to its failure or success.

METHODS

Retrospective study between 1998-2015 comparing in the cord accident diagnosed at delivery (by midwife or doctors according to mode of delivery): Patients with attempt ECV: Group 1 cephalic presentation after successful ECV with trial of labor, and Group 2 failed ECV followed by elective cesarean or trial of labor. Patients with no attempt ECV Group 3 spontaneous cephalic presentation matching for delivery date, maternal age, parity, body mass index, and delivery history with group 1, Group 4 Breech presentation without attempt ECV with trial of labor.

RESULTS

A total of 776 women with breech presentation were included (198 in group 1, 446 in group 2, 396 in group 3 and 118 in group 4). The prevalence of cord accident did not differ according to ECV attempt (17.08 % versus 18.9 %), to cephalic presentation (group 1: 24.7 % versus group 3: 25 %) and to breech presentation (group 2: 16.9 % versus group 4: 17.2 %). The trial of labor after failed ECV did not increase the risk of cord accident when compared with elective cesarean (17.4 % versus 16 %). A prolapse cord was only observed after trial of labor, i.e. in groups 1, 2 and 4 without difference (respectively 1, 0.8 and 1.7 %). In each group, the rate of cesarean was not different according to the presence of nuchal cord.

CONCLUSION

Success or failed External cephalic version is not associated with an increased risk of cord accident.

[Obstetrical APS: Is there a place for additional treatment to aspirin-heparin combination?]

Obstetrical APS is defined by thrombosis and/or obstetrical morbidity associated with persistent antiphospholipid antibodies. The aspirin and low molecular weighted heparin combination dramatically improved obstetrical outcome in APS patients. Several factors could be associated with obstetrical prognosis, as previous history of thrombosis, associated SLE, the presence of lupus anticoagulant and triple positivity of antiphospholipid antibodies. Obstetrical APS with isolated recurrent miscarriages is mostly associated with isolated anticardiolipids antibodies and have better obstetrical outcome. The pregnancy loss despite aspirin and heparin combination define the refractory obstetrical APS, and the prevalence could be estimated to 20-39%. Several other treatments have been used in small and open labeled studies, as steroids, intravenous immunoglobulins, plasma exchanges and hydroxychloroquine to improve the obstetrical outcome. Some other drugs as eculizumab and statins could also have physiopathological rational, but studies are necessary to define the place of these various drugs.

High Fasting Plasma Glucose during Early Pregnancy: A Review about Early Gestational Diabetes Mellitus

Fasting plasma glucose (FPG) is nowadays routinely measured during early pregnancy to detect preexisting diabetes (FPG ≥ 7 mmol/L). This screening has concomitantly led to identify early intermediate hyperglycemia, defined as FPG in the 5.1 to 6.9 mmol/L range, also early gestational diabetes mellitus (eGDM). Early FPG has been associated with poor pregnancy outcomes, but the recommendation by the IADPSG to refer women with eGDM for immediate management is more pragmatic than evidence based. Although eGDM is characterized by insulin resistance and associated with classical risk factors for type 2 diabetes and incident diabetes after delivery, it is not necessarily associated with preexisting prediabetes. FPG ≥ 5.1 mmol/L in early pregnancy is actually poorly predictive of gestational diabetes mellitus diagnosed after 24 weeks of gestation. An alternative threshold should be determined but may vary according to ethnicity, gestational age, and body mass index. Finally, observational data suggest that early management of intermediate hyperglycemia may improve prognosis, through reduced gestational weight gain and potential early introduction of hypoglycemic agents. Considering all these issues, we suggest an algorithm for the management of eGDM based on early FPG levels that would be measured in case of risk factors. Nevertheless, interventional randomized trials are still missing.

Fetal gender is not associated with either gestational diabetes mellitus or placental weight: A cohort study

AIM

This study assessed whether male fetal gender increases the risk of maternal gestational diabetes mellitus (GDM) and investigated the association with placental weight.

METHODS

The study included 20,149 women without pregestational diabetes who delivered singletons at our hospital between January 2002 and December 2010. There was universal screening for GDM, and all placentas were weighed at delivery.

RESULTS

GDM (affecting 14.2% of women) was not associated with fetal gender (male fetuses in women without and with GDM: 51.8% vs. 51.7%, respectively; P=0.957), and remained likewise after logistic-regression analysis of risk factors for GDM (OR: 1.007, 95% CI: 0.930-1.091; P=0.858). Placental weights were 600±126g, 596±123g, 584±118g and 587±181g in women with GDM/female, GDM/male, no GDM/female and no GDM/male fetuses, respectively (GDM effect: P=0.017; gender effect: P=0.41; GDM * gender effect: P=0.16).

CONCLUSION

The present results suggest that fetal gender is not associated with GDM and, while placental weights were higher in cases of GDM, there were still no gender effects.

Should fetal scalp blood sampling be performed in the case of meconium-stained amniotic fluid?

OBJECTIVE

To investigate the effect of using fetal scalp blood sampling on the risk of neonatal respiratory distress syndrome (NRDS) with meconium-stained amniotic fluid (MSAF).

METHODS

Prospective data collection with regard to MSAF during labor for low-risk term cephalic singleton live birth from 2012 to 2014. Maternal, obstetric and neonatal data were compared according to the occurrence of respiratory distress syndrome (RDS group) or not (no RDS group).

RESULTS

Of 515 newborns born through MSAF, 46 experienced RDS and from them 10 experienced meconium aspiration syndrome. No difference was observed according to maternal characteristic, abnormal fetal heart rate tracing pattern irrespective of its category and cesarean rate. Apgar at one minute was lower in the group RDS (7.6 versus 8.5, p < 0.05). The mean umbilical artery pH values did not differ between the two groups. Significant difference between newborns with and without RDS in terms of fetal scalp lactate sampling during the labor (71.1% versus 55.1%, p < 0.05), and neonatal care unit (NCU) admissions (22.8% versus 10.8%, p < 0.05). Secondary rather than primary meconium was associated with RDS when performing fetal scalp blood assessment (p < 0.05). A significant correlation between RDS, fetal scalp blood assessment and MSAF diagnosed during the first stage of labor (after spontaneous rupture of membranes or at amniotomy) was found.

CONCLUSION

In case of MSAF, fetal scalp blood sampling did not reduce the risk of RDS.

[Cornual pregnancy: Management and subsequent fertility]

OBJECTIVE

Cornual pregnancy is a rare entity, representing 2% of ectopic pregnancies. Its management is poorly codified and often guided by the clinical situation. The aim of our study was to describe the management of cornual pregnancies, subsequent fertility, and obstetric outcomes according to the management.

METHODS

Observational retrospective unicentric study. Nineteen patients hospitalized for cornual pregnancy between 2006 and 2015 were included. The data was collected with medical records and a phone standardized questionnaire. Patients were managed according to hemodynamic status by either systemic or local methotrexate injection or surgical corneal resection.

RESULTS

Among the 19 patients, 32% (6) were treated by systemic injection (one failure treated by surgical treatment) and 68% (13) underwent surgical treatment by cornual resection. The median HCG rate decrease was 33 days (16-62). Among the twelve patients with a desire for a new pregnancy, 7 (58%) became pregnant without assisted reproductive technology (2 following medical treatment and 5 following surgical resection). Histological analysis of uterine horn showed proximal fallopian tube lesions in 76.9% of case (chronic salpingitis, endosalpingiosis and adenomyosis).

CONCLUSION

Cornual pregnancies are at high risk of hemorrhagic rupture. Ectopic recidive may occur. Fertility and obstetrical outcomes following cornual pregnancy are not affected whatever the initial treatment. Other studies are needed to aid clinical management according to HCG level and ultrasound features.

Improving postpartum glucose screening after gestational diabetes mellitus: a cohort study to evaluate the multicentre IMPACT initiative

AIMS

To evaluate a mobilization campaign, the IMPACT initiative, which included multidisciplinary meetings, provision of information and a systematic prescription of an oral glucose tolerance test to improve the rate of glucose screening in women with gestational diabetes mellitus in the four largest maternity units in our area, starting in March 2011.

METHODS

We retrospectively compared the level of self-reported screening during the first 6 months postpartum of women who gave birth after having been diagnosed with gestational diabetes before (January 2009 to December 2010) and after the IMPACT campaign (April 2011 to February 2012).

RESULTS

We included 961 women (589 in the period before and 372 in the period after the campaign was initiated) with a mean ± SD age of 33.2 ± 5.3 years and BMI of 27.8 ± 5.3 kg/m². Multivariate analysis, stratified using a propensity score in order to limit bias caused by imbalance between both periods, showed that the postpartum screening rate was higher after the campaign began (48.9 vs 33.3%, odds ratio 1.7, 95% CI 1.1-2.5; P = 0.019) and higher in women who received insulin treatment during pregnancy (odds ratio 2.3, 95% CI 1.5-3.6; P < 0.001), consumed fruit and vegetables daily (odds ratio 1.6, 95% CI 1.1-2.4; P = 0.035) and did not smoke (smoking vs non-smoking: odds ratio 0.3, 95% CI 0.1-0.7; P = 0.01). There was no interaction between the campaign effect and these particular conditions. The proportion of oral glucose tolerance tests performed in women who underwent screening increased from 6.3 to 33.0%.

CONCLUSIONS

The IMPACT campaign increased postpartum screening, and the use the oral glucose tolerance test in particular. The effect of this initiative might be reinforced in women who are non-daily consumers of fruit and vegetables, smokers and those who do not receive insulin treatment during pregnancy.

Screening for dysglycaemia during pregnancy: Proposals conciliating International Association of Diabetes and Pregnancy Study Group (IADPSG) and US National Institutes of Health (NIH) panels

The International Association of Diabetes and Pregnancy Study Group (IADPSG) has proposed that blood glucose levels for the diagnosis of gestational diabetes mellitus (GDM) be the values associated with a 1.75-fold increase in the risk of neonatal complications in the Hyperglycaemia and Adverse Pregnancy Outcomes (HAPO) study. However, this recommendation was not adopted by the US National Institutes of Health (NIH) panel as it would have been responsible for a huge increase in the prevalence of GDM with no clear evidence of a reduction of events at such blood glucose values. Considering this aspect, we now propose the use of a blood glucose threshold combination associated with an odds-ratio of 2.0 for neonatal disorders [fasting plasma glucose (FPG)≥ 95 mg/dL, or a 1-h glucose value after a 75-g oral glucose tolerance test (OGTT)≥ 191 mg/dL or a 2-h glucose value ≥ 162 mg/dL] for GDM diagnosis. This would lead to a lower prevalence of GDM and concentrate medical resources on those with the highest risk of complications. This would also allow the use of a similar FPG value for both the diagnosis and therapeutic target of GDM. The IADPSG also proposed screening for dysglycaemia during early pregnancy, using FPG measurement with a similar threshold after 24 weeks of gestation. We propose the same strategy considering an FPG value ≥ 95 mg/dL as abnormal, but only after confirmatory measurements. We also believe that an OGTT should not be used before 24 weeks of gestation as normal values during that time are as yet unknown.

[Obstetric and neonatal outcomes of adolescent pregnancies: a cohort study in a hospital in Seine-Saint-Denis France]

OBJECTIVES

The aim of this study was to describe the characteristics, monitoring, obstetrical complications, childbirth and neonatal outcomes of pregnancies among minors in a cohort of adolescents from Seine-Saint-Denis (France).

PATIENTS AND METHODS

This is a retrospective, cohort, comparative study, conducted from January 1, 1996 to July 31, 2011, made from the database of Jean-Verdier hospital in Seine-Saint-Denis. Three groups were established: patients aged less than 16 years old, patients aged over 16 years old and under 18 years old compared to a group consisting of older primiparas from 18 to 25 years old. The criteria considered were the characteristics of pregnancy, terms of delivery, neonatal outcome and conduct of post-partum.

RESULTS

Minor patients were statistically more likely to be single, student, smoking and anemia compared to young adults. The obstetrical care was lower for minor compared to the control group with a number of consultations and ultrasounds lower (P < 0.001). Obstetrical complications were similar in the three groups outside of preterm labor. Adolescentes under 16 years old had a higher preterm delivery risk in multivariate analysis (RR = 0.33 CI 95% [0.12; 0.90] P = 0.03). Adolescents had fewer cesarean and instrumental deliveries (P < 0.05).

DISCUSSION AND CONCLUSION

Teenage pregnancy remains an important managing issue for maternities, particularly from a social standpoint. On the medical side, one preterm delivery appears to be more common among these adolescents.

Factors associated with screening for glucose abnormalities after gestational diabetes mellitus: baseline cohort of the interventional IMPACT study

INTRODUCTION

Although it is important to screen women who have had gestational diabetes mellitus (GDM) for abnormal post-partum glucose levels, such testing is rarely performed. The aim of this study was to use data from the first observational phase of the IMPACT study to determine rates of screening within 6 months of delivery in a multiethnic cohort, focusing in particular on the effects of social deprivation and the risk of future diabetes.

PATIENTS AND METHODS

To investigate the frequency of post-partum screening, charts were analyzed, and all women attending four centres located in a deprived area who had had GDM between January 2009 and December 2010 were contacted by phone. The Evaluation of Precarity and Inequalities in Health Examination Centres (EPICES) deprivation index and Finnish Diabetes Risk Score (FINDRISK) questionnaire were also evaluated.

RESULTS

Data were evaluable for 589 of the 719 women contacted (mean age: 33.4 ± 5.2 years; mean body mass index: 27.6 ± 5.4 kg/m(2)), and 196 (33.3%) reported having been screened. On multivariate analysis, factors associated with a lack of screening were smoking [odds ratio (OR): 0.42 (0.20-0.90), P<0.05], low consumption of fruit and vegetables [OR: 0.58 (0.39-0.82), P<0.01] and heavier offspring birth weight (P<0.05), although there were no differences in FINDRISK and EPICES scores between screened and unscreened women.

CONCLUSION

One-third of women who had had GDM reported having been screened for dysglycaemia at 6 months post-partum. However, it is expected that the interventional phase of the IMPACT study will increase screening rates, especially in women with the risk factors associated with lower screening rates during this observational phase.

[Is there more complications with pregnancies from the assisted reproductive technology than spontaneous pregnancies? A retrospective study over 6 years]

OBJECTIVES

Comparison of pregnancy pathologies (diabetes, high blood pressure, preeclampsia), the stages of delivery, the weight at birth, the method of delivery, and the neonatal outcome for spontaneous pregnancies, and pregnancies from assisted reproductive technology (ART) obtained by in vitro fertilization (IVF), by intra cytoplasmic sperm injection (ICSI) or intrauterine insemination (IUI) or ovulation induction.

PATIENTS AND METHODS

A retrospective study over 6 years from January 1st, 2003 and December 31st, 2008 including all births at Jean-Verdier hospital in Bondy, France (n=14,049) taking into account therapeutic abortions, late miscarriages and intrauterine fetal deaths. The population was divided into four groups: spontaneous pregnancies (SP), pregnancies resulting from IVF, those obtained by ICSI and those obtained by other modes of "simple" ART.

RESULTS

The distribution of the four populations is: SP: 96.5%, IVF: 1.20%, ICSI: 0.95% and other modes of "simple" ART: 1.35%. There is no significant difference in rates of high blood pressure, preeclampsia, HELLP syndrome, therapeutic abortions and intrauterine fetal deaths between the four populations studied. In contrast, ICSI has a rate of gestational diabetes significantly lower compared to the other three groups (6.7%). The terms of delivery are later and birth weight heavier for spontaneous pregnancies (P<0.05). For the singletons, the terms of delivery are later for "heavy" ART (IVF/ICSI) than for SP (P<0.05). For twins' birth weights, we notice that they are heavier for ICSI (P<0.05) and the terms of delivery are identical between the SP and heavy ART.

CONCLUSION

Our study showed no obstetrical complications for the heavy ART (IVF/ICSI). Pregnancies resulting from ICSI are more favourable than those from IVF and the most unfavourable are the one obtained by simple ART.

[A piece of needle of a cesarean section found 45 years later]

We report the case of a patient who had a caesarian section 45 years ago in whom was discovered a piece of needle during assessment of an endometrial cancer. This piece of needle, close to the small bowel, was found inside a hysterotomy scar but no complication occurred during all this time.
