Success factors for Bakri ™ balloon usage secondary to uterine atony: a retrospective, multicentre study

International audienceBACKGROUND:Post-partum haemorrhage (PPH) is one of the major obstetric complications and remains a cause of avoidable maternal mortality and morbidity.AIMS:The aims of this study were to assess the success and practicability of a Bakri™ balloon intrauterine tamponade for PPH and evaluate the predictive factors for success.MATERIALS AND METHODS:Women who received the Bakri™ balloon secondary to uterine atony and subsequent failure of routine drug treatment were identified at 6 hospital sites. Demographic, obstetric and specific factors in regard to the Bakri™ balloon use were recorded. Factors predictive of Bakri™ balloon success were evaluated.RESULTS:Intrauterine Bakri™ balloon tamponade was used in 36 women with uterine atony of which 28 received the balloon treatment after vaginal delivery: more than 50% of women (16/28) presented with PPH with blood loss > 1000 mL (mean blood loss: 1130 mL). Two balloon insertions failures were identified. Bakri balloon success was 100% for women with bleeding < 1000 mL. Twenty-five women (69%) did not require invasive treatment; seven (19%) required arterial embolisation and four (11%) surgical management. No short-term complication was observed after balloon insertion.CONCLUSION:The use of the Bakri™ balloon method, if undertaken early, is effective for the management of PPH with uterine atony (100% success compared to 69% overall success rate). Intrauterine balloon tamponade should included in PPH management guidelines

Incidence of obstetric anal sphincter injuries following breech compared to cephalic vaginal births

Abstract Introduction Obstetric anal sphincter injuries (OASIs) at the time of childbirth can lead to serious consequences including anal incontinence, dyspareunia, pain and rectovaginal fistula. These types of lesions and their incidence have been well studied after cephalic presentation deliveries, but no publications have specifically addressed this issue in the context of vaginal breech delivery. The goal of our study was to evaluate the incidence of OASIs following breech deliveries and compare it with cephalic presentation births. Methods This was a retrospective cohort study involving 670 women. Of these, 224 and 446 had a vaginal birth of a fetus in the breech (breech group) and cephalic (cephalic group) presentations respectively. Both groups were matched for birthweight (± 200 g), date of delivery (± 2 years) and vaginal parity. Main outcome of interest was to evaluate the incidence of OASIs following breech vaginal birth compared to cephalic vaginal births. Secondary endpoints were the incidence of intact perineum or first-degree tear, second-degree perineal tear and rates of episiotomies in each group. Results There was no statistically significant difference in OASIs incidence between the breech and cephalic groups (0.9% vs. 1.1%; RR 0.802 (0.157; 4.101); p = 0.31). There were more episiotomies in the breech group (12.5% vs. 5.4%, p = 0.0012) and the rate of intact or first-degree perineum was similar in both groups (74.1% vs. 75.3%, p = 0.7291). A sub-analysis excluding patients with episiotomy and history of OASIs did not show any statistically significant difference either. Conclusion We did not demonstrate a significant difference in the incidence of obstetric anal sphincter injuries between women who had a breech vaginal birth compared to cephalic

Risk of new-onset urinary incontinence 3 and 12 months after vaginal or cesarean delivery of twins: Part I

International audiencentroduction and hypothesis: Our purpose was to compare the prevalence of urinary incontinence (UI) 3 and 12 months after vaginal vs cesarean delivery of twins after 34 weeks of gestation.Methods: This was a multicenter prospective cohort study conducted at 172 French maternity units and included 2812 primiparous women with twins with no prior history of UI. Participants were enrolled at the time of delivery and followed up to 12 months postpartum. The primary outcome was the prevalence of UI, both stress and urge, 3 months postpartum, based on the patient reporting any frequency of urine leakage to the first question of the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF). The Pelvic Floor Distress Inventory - Short Form 20 (PFDI-20), Pelvic Floor Impact Questionnaire - Short Form 7 (PFIQ-7), Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12), and Medical Outcome Study Short Form-12 (SF-12) were also used.Results: The ICIQ-SF was completed by 1155 (39.8%) and 800 (27.5%) women, respectively, at 3 and 12 months postpartum; 556 (48%) had delivered vaginally and 599 (52%) by cesarean section. The prevalence of UI at 3 months was 26% overall and was significantly higher in the vaginal delivery group at both 3 months (35% vs 17% in the cesarean group, p 25 in early pregnancy (OR 1.620, 95% CI 1.188-2.209, p = 0.0023).Conclusions: Vaginal delivery is a risk factor for UI at 3 months after twin birth

Sperm quality and paternal age: effect on blastocyst formation and pregnancy rates

Abstract Background Several studies suggest a decrease in sperm quality in men in the last decades. Therefore, the aim of this work was to assess the influence of male factors (sperm quality and paternal age) on the outcomes of conventional in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). Methods This retrospective study included all couples who underwent IVF or ICSI at Montpellier University Hospital, France, between 1 January 2010 and 31 December 2015. Exclusion criteria were cycles using surgically retrieved sperm or frozen sperm, with pre-implantation genetic diagnosis or using frozen oocytes. The primary outcomes were the blastulation rate (number of blastocysts obtained at day 5 or day 6/number of embryos in prolonged culture at day 3) and the clinical pregnancy rate. The secondary outcomes were the fertilization and early miscarriage rates. Results In total, 859 IVF and 1632 ICSI cycles were included in this study. The fertilization rate after ICSI was affected by oligospermia. Moreover, in ICSI, severe oligospermia (lower than 0.2 million/ml) led to a reduction of the blastulation rate. Reduced rapid progressive motility affected particularly IVF, with a decrease of the fertilization rate and number of embryos at day 2 when progressive motility was lower than 32%. Paternal age also had a negative effect. Although it was difficult to eliminate the bias linked to the woman\u2019s age, pregnancy rate was reduced in IVF and ICSI when the father was older than 51 and the mother older than 37\ua0years. Conclusions These results allow adjusting our strategies of fertilization technique and embryo transfer. In the case of severe oligospermia, transfer should be carried out at the cleaved embryo stage (day 2\u20133) due to the very low blastulation rate. When the man is older than 51\ua0years, couples should be aware of the reduced success rate, especially if the woman is older than 37\ua0years. Finally, promising research avenues should be explored, such as the quantification of free sperm DNA, to optimize the selection of male gametes

Cryopreserved embryo replacement is associated with higher birthweight compared with fresh embryo: multicentric sibling embryo cohort study

International audienceBirth weight (BW) is higher after frozen embryo transfer (FET) than after fresh embryo replacement. No study has compared the BW of siblings conceived using the same oocyte/embryo cohort. The aim of this study was to determine whether the freezing-thawing procedure is involved in such difference. Multicenter study at Montpellier University Hospital, Clinique Ovo, Canada and Grenoble-Alpes University Hospital. The first cohort (Fresh/FET) included in vitro fertilization (IVF) cycles where the older was born after fresh embryo transfer (n = 158) and the younger after transfer of frozen supernumerary embryos (n = 158). The second cohort (FET/FET) included IVF cycles where older and younger were born after FET of embryos from the same cohort. The mean adjusted BW of the FET group was higher than that of the fresh group (3508.9 ± 452.4 g vs 3237.7 ± 463.3 g; p < 0.01). In the FET/FET cohort, the mean adjusted BW was higher for the younger by 93.1 g but this difference is not significant (3430.2 ± 347.6 g vs 3337.1 ± 391.9 g; p = 0.3789). Our results strongly suggest that cryopreservation is directly involved in the BW variation. Comparing BW difference between Fresh/FET cohort and FET/FET one, it suggests that parity is not the only responsible, increasing the role of cryopreservation step in BW variation

Rilpivirine in HIV-1-positive women initiating pregnancy: to switch or not to switch?

International audienceBackgroundSafety data about rilpivirine use during pregnancy remain scarce, and rilpivirine plasma concentrations are reduced during second/third trimesters, with a potential risk of viral breakthroughs. Thus, French guidelines recommend switching to rilpivirine-free combinations (RFCs) during pregnancy.ObjectivesTo describe the characteristics of women initiating pregnancy while on rilpivirine and to compare the outcomes for virologically suppressed subjects continuing rilpivirine until delivery versus switching to an RFC.MethodsIn the ANRS-EPF French Perinatal cohort, we included women on rilpivirine at conception in 2010–18. Pregnancy outcomes were compared between patients continuing versus interrupting rilpivirine. In women with documented viral suppression (<50 copies/mL) before 14 weeks of gestation (WG) while on rilpivirine, we compared the probability of viral rebound (≥50 copies/mL) during pregnancy between subjects continuing rilpivirine versus those switching to RFC.ResultsAmong 247 women included, 88.7% had viral suppression at the beginning of pregnancy. Overall, 184 women (74.5%) switched to an RFC (mostly PI/ritonavir-based regimens) at a median gestational age of 8.0 WG. Plasma HIV-1 RNA nearest delivery was <50 copies/mL in 95.6% of women. Among 69 women with documented viral suppression before 14 WG, the risk of viral rebound was higher when switching to RFCs than when continuing rilpivirine (20.0% versus 0.0%, P = 0.046). Delivery outcomes were similar between groups (overall birth defects, 3.8/100 live births; pregnancy losses, 2.0%; preterm deliveries, 10.6%). No HIV transmission occurred.ConclusionsIn virologically suppressed women initiating pregnancy, continuing rilpivirine was associated with better virological outcome than changing regimen. We did not observe a higher risk of adverse pregnancy outcomes
