To validate a mathematical model to predict the mean time to delivery (TTD) following cervical ripening with dinoprostone vaginal insert (DVI), and assess its impact on the risk of nocturnal deliveries.We performed a case-control retro-prospective study at Angers University Hospital. In the control group, we retrospectively included 405 patients who underwent cervical ripening with DVI between 01/2015 and 09/2016. Based on the delivery outcomes, we developed a mathematical model that integrates all the factors influencing TTD following cervical ripening with DVI. In the study group, we prospectively included 223 patients who underwent cervical ripening with DVI between 11/2017 and 11/2018. The timing of insertion was calculated using the mathematical model developed in the control group, in order to prevent the occurrence of nocturnal deliveries.The calculated mean TTD was significantly shorter than the real mean TTD (21h46 min ± 3h28 min versus 25h38 min ± 12h10 min, p 0.001), and for 44% of patients, there was at least 10 h difference between the two. The real TTD (25h38 min ± 12H10 min versus 20h39 min ± 10h49, p 0.001), and the rate of nocturnal deliveries (30.5% versus 21.2%, p = 0.01) were significantly higher in the study group compared to the control group.The mathematical model did not help predicting TTD following cervical ripening with DVI, and or reducing the number of nocturnal deliveries.

Introduction Pelvic lymph node dissection has been the standard of care for patients with early cervical cancer. Sentinel node (SN) mapping is safe and feasible and may increase the detection of metastatic disease, but benefits of omitting pelvic lymph node dissection in terms of decreased morbidity have not been demonstrated. Materials and methods In an open-label study, patients with early cervical carcinoma (FIGO 2009 stage IA2 to IIA1) were randomly assigned to SN resection alone (SN arm) or SN and pelvic lymph node dissection (SN + PLND arm). SN resection was followed by radical surgery of the tumour (radical hysterectomy or radical trachelectomy). The primary end-point was morbidity related to the lymph node dissection; 3-year recurrence-free survival was a secondary end-point. Results A total of 206 patients were eligible and randomly assigned to the SN arm (105 patients) or SN + PLND arm (101 patients). Most patients had stage IB1 lesion (87.4%). No false-negative case was observed in SN + PLND arm. Lymphatic morbidity was significantly lower in the SN arm (31.4%) than in the SN + PLND arm (51.5%; p = 0.0046), as was the rate of postoperative neurological symptoms (7.8% vs. 20.6%, p = 0.01, respectively). However, there was no significant difference in the proportion of patients with significant lymphoedema between the two groups. During the 6-month postoperative period, the difference in morbidity decreased over time. The 3-year recurrence-free survival was not significantly different (92.0% in SN arm and 94.4% in SN + PLND arm). Conclusion SN resection alone is associated with early decreased lymphatic morbidity when compared with SN + PLND in early cervical cancer.

Introduction Serum oestradiol concentration at the time of frozen embryo transfer (FET) in artificial cycle are lower when using transdermal administration of oestrogen for endometrial preparation compared to the vaginal route. This difference could have consequences for placentation and establishment of maternal-foetal circulation. The aim of our study was to compare the birth weight of newborns and the perinatal issues after FET in an artificial cycle with regard to the route of administration of oestrogens. Methods Retrospective monocentric cohort study in the medically assisted reproduction department of the University Hospital of Angers, France, between January 2017 and October 2020. Inclusion criteria were age >18 years old and one live birth after FET in an artificial cycle. The main outcome was the birth weight of the newborns. The choice of oestrogens administration (transdermal or vaginal) was left to the patient. Results 804 FET in artificial cycle were included in our study. Oestrogens were administrated in 356/804(36.6%) patients using transdermal route and in 448/804(45.9%) patients using vaginal route. There were 68/345 (19.1%) live births in the transdermal group and 85/448 (19%) in the vaginal group. There was no difference in the birth weight of the newborns (3320[2100-4165] grams in the transdermal group vs 3327.5[915-4650] grams in the vaginal group, p=0.72). All the other perinatal issues were comparable between the two groups. Conclusion Birth weights and perinatal issues were comparable with regard to the route of administration of oestrogens (vaginal or transdermal) in the context of endometrial preparation before FET in an artificial cycle.

Objective To evaluate whether manual rotation of fetuses in occiput posterior positions at full dilation increases the rate of spontaneous vaginal delivery. Methods In an open, single-center, randomized controlled trial, patients with a term, singleton gestation, epidural analgesia, and ultrasonogram-confirmed occiput posterior position at the start of the second stage of labor were randomized to either manual rotation or expectant management. Our primary endpoint was the rate of spontaneous vaginal delivery. Secondary endpoints were operative vaginal delivery, cesarean delivery, and maternal and neonatal morbidity. Analyses were based on an intention-to-treat method. A sample size of 107 patients per group (n=214) was planned to detect a 20% increase in the percent of patients with a spontaneous vaginal delivery (assuming 60% without manual rotation vs 80% with manual rotation) with 90% power and alpha of 0.05. Results Between February 2017 and January 2020, 236 patients were randomized to either manual rotation (n=117) or expectant management (n=119). The success rate of the manual rotation maneuver, defined by conversion to an anterior position as confirmed by ultrasonogram, was 68%. The rate of the primary endpoint did not differ between the groups (58.1% in manual rotation group vs 59.7% in expectant management group (risk difference -1.6; 95% CI -14.1 to 11.0). Manual rotation did not decrease the rate of operative vaginal delivery (29.9% in manual rotation group vs 33.6% in expectant management group (risk difference -3.7; 95% CI -16.6 to 8.2) nor the rate of cesarean delivery (12.0% in manual rotation group vs 6.7% in expectant management group (risk difference 5.3; 95% CI -2.2 to 12.6). Maternal and neonatal morbidity was also similar across the two groups. Conclusion Manual rotation of occiput posterior positions at the start of second stage of labor does not increase the rate of vaginal delivery without instrumental assistance. Clinical trial registration ClinicalTrials.gov, NCT03009435.

Urinary incontinence is a common health problem that impacts the quality of life of women at different ages. Its physiopathology is not unequivocal, and it is necessary to consider the stress urinary incontinence (SUI), the overactive bladder syndrome and the mixed incontinence (MUI). According to the type of incontinence, its impact on the quality of life and age of the patients, therapeutic strategies are currently summarized in physiotherapy, surgery and drug treatments. We already know the benefit/risk ratio of each of these strategies. Our objective is to evaluate the potential effectiveness and safety of the VEL, an innovative vaginal laser technique (VEL – Vaginal Erbium Laser, erbium yttrium-aluminum-garnet -Er: YAG) a non-invasive laser proposed as a treatment for SUI, overactive bladder syndrome and MUI. The mechanisms of action of lasers are discussed in general and those of VEL in particular with the description of the Smooth® mode. To do this, we have collected the 21 published studies including the first randomized vs. placebo and two pilot studies of intra-urethral VEL. In conclusion: VEL procedures already have their place between the rehabilitation of the perineal floor and surgery. Further properly sized, randomized studies are needed to evaluate the laser treatments in comparison with other therapies, as well as to assess the duration of the therapeutic effects and the safety of repeated applications.

International audience; Objectives: In 2016, the European Society of Gynecology Oncology (ESGO) published indicators defining the quality of surgical management of advanced ovarian cancer. The objective of the study was to assess the quality of ovarian cancer patient management in regional centers authorized for gynecological cancer, based on the ESGO list of quality indicators. Methods: A multicenter retrospective observational cohort study was conducted from January 1 to June 30, 2016. The following quality indicators 1 "rate of complete surgical resection", 4 "center participating in clinical trials in gynecologic oncology", 5 "treatment planned and reviewed at a multidisciplinary team meeting", 6 "required preoperative workup", 8 "minimum required elements in operative reports" and 9 "minimum required elements in pathology reports" were selected. Results: 91 patients were evaluated in 16 centers. The required preoperative workup was incomplete in 25% of cases. Treatment was not planned at a multidisciplinary team meeting for 24%. An evaluation score of peritoneal involvement was included in 40% of the operative reports and the quality of surgical resection was reported in 72%. Primary surgery was most often performed in a peripheral hospital (48%), interval surgery in a private center (37%), and closure surgery in a regional cancer center (43%). No institution respected the six quality indicators evaluated. One regional cancer center respected five items and two private centers did not respect any. Conclusion: Whilst the ESGO quality indicators provide objective, validated and evaluable support which centers can use to improve quality of care, we observed heterogeneous practices amongst the centers evaluated.

Objectives: To investigate the perinatal outcomes of women with a history of female genital mutilation (FGM) who underwent clitoral reconstruction (CR) compared with women with FGM who did not undergo CR. Design: Retrospective case-control study Setting: Angers University Hospital, between 2005 and 2017 Methods: Inclusion criteria: pregnant women >18 years who underwent CR after FGM. Only the first subsequent delivery after CR was included. Each woman with CR was matched for age, ethnicity, FGM type, parity, and gestational age at the time of delivery with two women with FGM who did not undergo CR during the same period of time. Main outcome measures: at birth: need for episiotomy and intact perineum Results: 84 women were included (28 in the CR group; 56 in the control group). In the CR group, patients required significantly fewer episiotomies (5/17[29.4%]) compared to the control group (28/44[63.6%], p=0.02), even after excluding operative vaginal deliveries (2/13[15.4%] vs 21/36[58.3], p

Objective: AUB-O,E,N is treated first with medical management, followed by surgery, which failure or complications have significant burden. The objective was to perform a cost-effectiveness analysis of four surgical strategies, comparing cost and avoided failure rate, using the French PMSI database. Design: Retrospective analysis performed using the French exhaustive national hospital discharge database (PMSI). Population: All incident 35-55 year-old women operated on for four types of AUB-O,E,N surgery (2nd generation, 1st generation, curettage or hysterectomy) between 2009 and 2014 were included. Methods : They were followed to collect rehospitalizations related to failure or complication and their cost, during at least 18 months. Hospital costs were estimated using the French tariffs in 2017\euro. Main Outcome measures : A cost-effectiveness analysis was performed comparing each surgical procedure to 2G, in hospitalization costs and rate of patients without failure. Results : The study included 88,154 patients. At 18 months, mean cost per patient was \euro2,448 for 2G, \euro2,100 for 1G, \euro2,275 for curettage and \euro4,157 for hysterectomy. Hysterectomy was the most effective strategy in terms of absence of failure, but also the most expensive, with an incremental cost of \euro24,008 per additional % of patient without failure. Even with a mean cost similar to 2G, curettage was the least effective strategy with a failure rate reaching 20.6% at 18 months. 1G was less expensive but also less effective than 2G, with an economy of \euro13,078 per % of patient without failure loss. Conclusion: 1G and 2G techniques are the most efficient strategie

Endometriosis and infertility are closely linked, but the underlying mechanisms are still poorly understood. This study aimed to evaluate the impact of endometriosis on in vitro fertilization (IVF) parameters, especially on embryo quality and IVF outcomes. A total of 1124 cycles with intracytoplasmic sperm injection were retrospectively evaluated, including 155 cycles with endometriosis and 969 cycles without endometriosis. Women with endometriosis had significantly lower ovarian reserve markers (AMH and AFC), regardless of previous ovarian surgery. Despite receiving significantly higher doses of exogenous gonadotropins, they had significantly fewer oocytes, mature oocytes, embryos, and top-quality embryos than women in the control group. Multivariate analysis did not reveal any association between endometriosis and the proportion of top-quality embryo (OR = 0.87, 95% CI [0.66&ndash, 1.12], p = 0.3). The implantation rate and the live birth rate per cycle were comparable between the two groups (p = 0.05), but the cumulative live births rate was significantly lower in in the endometriosis group (32.1% versus 50.7%, p = 0.001), as a consequence of the lower number of frozen embryos. In conclusion, endometriosis lowers the cumulative live birth rates by decreasing the number of embryos available to transfer, but not their quality.

To determine if a modification of the cytokine profile occurs in the follicular fluid (FF) of women with endometriosis undergoing in vitro fertilization (IVF), we performed a prospective observational study from January 2018 to February 2019. In total, 87 women undergoing IVF were included: 43 for severe endometriosis-related infertility and 40 controls with other causes of infertility. The cytokine profile of the FF was determined by multiplex fluorescent-bead-based technology allowing the measurement of 59 cytokines. Monocyte Chemoattractant Protein 1 (MCP-1) was the only variable retained in the multivariate analysis. We identified two subgroups of patients in the endometriosis group: MCP-1-low group (n = 23), which had FF MCP-1 levels comparable to the control group, and MCP-1-high (n = 20), which had significantly higher FF levels. Only patients in the MCP-1-high group had a significantly altered cytokine profile in the FF, and had a significantly higher serum estradiol level (p = 0.002) and a significantly lower number of oocytes recovered (p = 0.01) compared to the MCP-1-low and the control group. Our study has shown an alteration of the oocyte microenvironment in women with endometriosis associated with high follicular fluid levels of MCP-1, allowing the identification of a subgroup of endometriosis patients with a potentially worse prognosis.

International audience; Objective: Ovarian ageing is one of the commonest causes of infertility in patients consulting for assisted reproductive technology. The composition of the follicular fluid (FF), which reflects the exchanges between the oocyte and its microenvironment, has been extensively investigated to determine the metabolic pathways involved in various ovarian disorders. Considering the importance of cytokines in folliculogenesis, we focused on the cytokine profile of the FF during ovarian ageing. Material and methods: Our cross-sectional study assesses the levels of 27 cytokines and growth factors in the FF of two groups of women undergoing in vitro fertilization. One group included 28 patients with ovarian ageing clinically characterized by a diminished ovarian reserve (DOR), and the other group included 29 patients with a normal ovarian reserve (NOR), serving as controls. Results: With univariate analysis, the cytokine profile was found to differ significantly between the two groups. After adjustment of the p-values, platelet-derived growth factor-BB (PDGF-BB) was the only cytokine with a significantly lower concentration in the DOR group (7.34 AE 16.11 pg/mL) than in the NOR group (24.39 AE 41.38 pg/mL) (p = 0.005), independently of chronological age. Conclusion: Thus, PDGF-BB would seem to be implicated in the physiopathology of DOR, potentially in relation to its role in folliculogenesis or in the protection against oxidative stress.

The objective was to compare the endometrial thickness (ET) in a frozen embryo transfer (FET) cycle between transdermal and vaginal estrogen. Our secondary objectives were to compare the patient satisfaction and the pregnancy outcomes. Prospective monocentric cohort study between 01/2017 and 12/2017 at a single institution. Choice of administration was left to the patient. 119 cycles had transdermal estrogen (T-group) and 199 had vaginal estrogen (V-group). The ET at 10 ± 1 days of treatment was significantly higher in the T-group compared to the V-group (9.9 vs 9.3 mm, p = 0.03). In the T-group, the mean duration of treatment was shorter (13.6 vs 15.5 days, p

A congenital malformation of the head, neck or thorax can lead to upper airway compression with a risk of asphyxia or neonatal death. To secure and protect the upper airway, the Ex Utero Intrapartum Therapy (EXIT) procedure has been developed. The procedure allows delivery of the fetus via a hysterotomy while relying on the placenta as the organ of respiration for the fetus prior to clamping of the umbilical cord. A high level of expertise is necessary for successful completion of the EXIT procedure, which is not void of maternal and fetal risks. In this literature review, we present the indications, procedure methods and materno-fetal complications associated with the EXIT procedure.

Objective The objective of the study was to analyse the pregnancy rate after curettage, 1G (Endometrial resection) and 2G (Endometrial ablation) procedures in women with abnormal uterine bleeding (AUB-O,E,N) to evaluate the rate of pregnancy following these procedures and to improve pre and post-therapeutic women information. Methods This retrospective study analyzed data extracted from the French Hospital medical information database. All hospital stays with a diagnostic code for AUB and an appropriate surgical procedure coded between 2009 and 2015 were identified. A total of 109,884 women were included. Of these, 88,165 were followed up for 18 months, 80,054 for 24 months and 33,251 for 60 months. Outcomes were compared between second generation (2G) procedures, first-generation (1G) procedures (endometrial resection) and curettage. The rate of pregnancy was the primary end point. Results 7,863 women underwent a 2G surgical procedure (7.2%), 39,935 a 1G procedure (36.3%) and 38,923 a curettage (35.4%). The mean age of the women was 46 years (IC.95: 36.7-52.5), with no difference in age between groups. The rate of pregnancy after 2G, 1G and curettage was respectively 13 (1.5%), 617 (10.1%) and 1,025 (11.1%). The primary endpoint was significantly different between 2G and 1G and curettage (p Conclusion 2G procedures result in lower risk of pregnancy without requiring specific training for surgeons. However, endometrial ablation cannot be considered as a sterilization method nor an effective contraceptive procedure. In the absence of sterilization of either partner, women should continue to use contraception whatever their age and menstrual status.

Resume Objectif Comparer l’efficacite d’une mini-bandelette ALTIS® et d’une bandelette sous-uretrale (BSU) classique transobturatrice TVT-ABBREVO® pour le traitement de l’incontinence urinaire d’effort feminine. Methodes Une etude retrospective monocentrique incluait toutes les patientes operees par BSU transobturatrice (TVT-ABBREVO®) ou mini-bandelette (ALTIS®) en 2015, au centre hospitalier universitaire d’Angers. Le taux de succes etait defini par l’amelioration de la qualite de vie definie par un score PGI-I (Patient Global Impression of Improvement) compris entre 1 et 3, l’absence de fuite urinaire lors d’un test a la toux a l’examen clinique, et l’absence de fuite urinaire a l’effort rapportee sur le questionnaire USP (Urinary Symptom Profile). La morbidite liee aux bandelettes ainsi que les donnees peroperatoires etaient egalement repertoriees. Resultats Quatre-vingt-douze patientes etaient incluses (39 dans le groupe ALTIS et 53 dans le groupe ABBREVO). Le suivi moyen etait de 13,55 mois. Le taux de succes n’etait pas significativement different dans le groupe ALTIS que ce soit pour le test a la toux negatif (89,7 % vs 94,3 % dans le groupe ABBREVO, p = 0,45), pour l’absence de fuite urinaire rapportee dans le questionnaire USP (87,2 % vs 90,6 % dans le groupe ABBREVO, p = 0,61), ou pour l’amelioration de la qualite de vie avec un score PGI-I entre 1 et 3 (82,1 % vs 86,8 % dans le groupe ABBREVO, p = 0,53). En revanche, plus de patientes etaient pleinement satisfaites avec un score PGI-I a 1 dans le groupe ABBREVO (67,9 % vs 46,2 % dans le groupe ALTIS, p = 0,03). La douleur postoperatoire immediate etait significativement moins intense dans le groupe ALTIS que dans le groupe ABBREVO (score EVA moyen a 0,5 vs 1,3, p = 0,01) mais cette difference disparaissait a une semaine de la chirurgie. Les taux des autres complications etaient similaires dans les deux groupes. Conclusion Les resultats fonctionnels des bandelettes ALTIS et TVT-ABBREVO® semblent similaires dans le traitement de l’incontinence urinaire d’effort feminine.

Resume Objectif L’objectif de ce travail est d’evaluer la place des nouveaux traitements dans la prise en charge de l’endometriose en dehors du contexte d’infertilite. Methodes Une revue de la litterature a ete effectuee en consultant les donnees Medline jusqu’en juillet 2017. Resultats Le dienogest est efficace par rapport au placebo a court terme (NP2) et long terme (NP4) pour le traitement de l’endometriose douloureuse. En comparaison aux agonistes de la GnRH, le dienogest est aussi efficace en termes de diminution de douleur et d’amelioration de la qualite de vie chez les patientes non operees (NP2), de meme que pour la recidive des lesions d’endometriose et la symptomatologie en postoperatoire (NP2). Les donnees concernant les antagonistes de la GnRH, les modulateurs selectifs des recepteurs a la progesterone de meme que les inhibiteurs selectifs (anti-TNF-α, inhibiteurs des metalloproteases matricielles, inhibiteurs des facteurs de croissance de l’angiogenese) sont insuffisantes pour apporter une preuve de l’interet en pratique clinique pour la prise en charge de l’endometriose douloureuse (NP3). Conclusion Le dienogest est recommande en seconde intention pour la prise en charge de l’endometriose douloureuse (Grade B). En l’absence de donnees suffisantes, les anti-aromatases, l’elagolix, les SERM, les SPRM et les anti-TNF-α ne sont pas recommandes pour la prise en charge de l’endometriose douloureuse (Grade C).

The objective of this study was to identify the factors predictive of the success of external cephalic version (ECV).A single-centre retrospective observational study was performed in the maternity ward of the Angers University Hospital, France, between January 2010 and May 2020. The study included all patients (n = 613) for whom an ECV was performed for a breech or transverse foetus. The primary endpoint was measured by the success of the ECV, defined by the visualisation, using pelvic ultrasound, of the foetus in cephalic presentation immediately after the manoeuvre. Following to the ECV, the cohort was separated into two groups; ECV Success and ECV Failure. In order to determine the predictive factors of success, a logistic regression model was performed, including the parameters of: parity, foetal presentation during ECV, the side of the foetal back, placental location, type of operator and maternal age. The results are presented as (odds ratio [confidence intervals]; p-value). The significance threshold was defined by a p-value0.05.The ECV success rate was 21.4% (131/613). The factors predictive of the success of ECV were: transverse foetal presentation (2.7 [1.3-5.6]; p0.01); a senior physician operator (1.6 [1.2-2]; p0.01); multiparity (1.6 [1.2-2]; p0.01); non anterior placental localization (1.4 [1.1-2]; p0.01). A number of attempts greater than 3 were significantly associated with reduced chances of success (0.3 [0.2-0.4]; p0.01).The study shows that transverse foetal presentation, a senior physician operator, multiparity, as well as a non-anterior placental location are factors predictive of the success of ECV. Knowledge of these factors can improve the information given to patients.

Introduction The coronavirus SARS-CoV-2 (COVID-19) pandemic has put tremendous pressure on the French healthcare system. Almost all hospital departments have had to profoundly modify their activity to cope with the crisis. In this context, the surgical management of cancers has been a topic of debate as care strategies were tailored to avoid any delay in treatment that could be detrimental to patient wellbeing while being careful not to overload intensive care units. The primary objective of this study was to observe changes in the surgical management of pelvic cancers during the COVID-19 pandemic in France. Material and Methods This study analyzed data from the prospective multi-center cohort study conducted by the French Society for Pelvic and Gynecological Surgery (SCGP) with methodological support from the French (FRANCOGYN) Group. All members of the SCGP received by e-mail a link allowing them to include patients who were scheduled to undergo gynecological carcinologic surgery between March 16th 2020 and May 11th 2020. Demographic data, the characteristics of cancers and the impact of the crisis in terms of changes to the usual recommended coarse of care were collected. Results A total of 181 patients with a median age 63 years were included in the cohort. In total, 31 patients had cervical cancer, 76 patients had endometrial cancer, 52 patients had ovarian or tubal cancer, 5 patients had a borderline tumor of the ovary, and 17 patients had vulvar cancer. During the study period, the care strategy was changed for 49 (27%) patients with postponed for 35 (19.3%) patients, and canceled for 7 (3.9%) patients. Surgical treatment was maintained for 139 (76.8%) patients. Management with neoadjuvant chemotherapy was offered to 19 (10,5%) patients and a change in surgical choice was made for 5 (2,8%) patients. In total, 8 (4,4%) patients tested positive for COVID-19. Data also shows a greater number of therapeutic changes in cases of ovarian cancer as well as a cancelation of a lumbo-aortic lymphadenectomy in one patient with cervical cancer. Hospital consultants estimated a direct detrimental impact of the COVID-19 pandemic for 39 patients, representing 22% of gynecological cancers. Conclusion This study provided observational data of the impact of the COVID-19 health crisis on the surgical management of gynecological cancers.

Objectives To characterize and describe treatment with ulipristal acetate (UPA) in a preoperative setting and to evaluate the safety, effectiveness, and Health Related Quality of Life (HRQoL) outcomes in a French population treated according to standard clinical practice. Materials and methods Multicentre, prospective, non-interventional study (PREMYA) of patients diagnosed with moderate to severe symptoms of uterine fibroids and undergoing a preoperative treatment with UPA 5 mg (Esmya ® ). Patients were followed for a total of 15 months (3 months UPA treatment and 12 months after). Data were collected approximatively every 3 months according to centre usual visit schedule. Results A total of 206 women were enrolled in France, of whom 197 were found to be eligible for data analysis. Physicians’ assessments of patients’ overall symptomatic changes, as measured on the Clinical Global Impression-Improvement (CGI-I) scale, indicated that 83.7% of patients were improved at end of treatment (month 3). On the patients’ treatment benefit scale (PTBS), 94.7% of patients reported an improvement. These 2 measurements, pain and quality of life, remained improved after treatment cessation and during the entire period of follow-up. Only 58.4% of patients underwent surgery within the timeframe of the study follow-up of which the majority were of a conservative/minimal invasive nature. Conclusion Many patients did not undergo surgery during the planned 12 months follow-up period after treatment whereas all patients had an indication of surgery. All measurements of treatment outcome were markedly improved by 3 months of UPA 5 mg treatment. Clinical trial number NCT01635452 .

Recurrent pregnancy loss is an important reproductive health issue, affecting 2%–5% of couples. Common established causes include uterine anomalies, antiphospholipid syndrome, hormonal and metabolic disorders, and cytogenetic abnormalities. Other etiologies have been proposed but are still considered controversial, such as chronic endometritis, inherited thrombophilias, luteal phase deficiency, and high sperm DNA fragmentation levels. Over the years, evidence-based treatments such as surgical correction of uterine anomalies or aspirin and heparin for antiphospholipid syndrome have improved the outcomes for couples with recurrent pregnancy loss. However, almost half of the cases remain unexplained and are empirically treated using progesterone supplementation, anticoagulation, and/or immunomodulatory treatments. Regardless of the cause, the long-term prognosis of couples with recurrent pregnancy loss is good, and most eventually achieve a healthy live birth. However, multiple pregnancy losses can have a significant psychological toll on affected couples, and many efforts are being made to improve treatments and decrease the time needed to achieve a successful pregnancy. This article reviews the established and controversial etiologies, and the recommended therapeutic strategies, with a special focus on unexplained recurrent pregnancy losses and the empiric treatments used nowadays. It also discusses the current role of preimplantation genetic testing in the management of recurrent pregnancy loss.

Introduction: Congenital neutropenia (CN) is characterized by chronic neutropenia due to a constitutional genetic defect.1 To date, these diseases have not been considered to be frequently associated with malignant solid tumors, unlike the risk of secondary myelodysplastic syndrome leukemia, which is well-known in CN. Methods: The French Severe Chronic Neutropenia Registry (FSCNR) has prospectively enrolled CN patients since 1993. Solid tumors, identified during routine patient follow-up, were classified according to WHO criteria. We included localized lymphoma in the spectrum of malignant solid tumors. We calculated the incidence of malignant solid tumors in a cohort of CN patients. Results: Among 868 patients with various CN subtypes followed for a total of 16617 person-years, 24 patients who developed a malignant solid tumor were identified. Those cancers are described in Table 1, including the CN genetic anomaly. Cancers were almost always diagnosed in adulthood, with median age at diagnosis of 38.1 (range 10-72) years; only 3 cancers were diagnosed before age of 20 years. The cancer rate was 1.2% at 30 years of age, 7% at 40 years and 24% at 50 years (Fig. 1A). The risk-of-cancer percentages depended mainly on the associated genetic deficiency. Solid tumors were roughly distributed as follows: 33% among WHIM (CXCR4) patients, 5.3% among GATA2 patients, 2.7% among ELANE patients, 1.9 % among SBDS patients and 0.8% among for all other subtypes combined (Fig. 1B). Human papillomavirus (HPV) was the cause of cancer for 2/5 in WHIM patients and 2/6 in GATA2 patients. Three Lymphoma were identified, one in GATA2 patient and 2 in WHIM patients. Notably, our cohort's follow-up is skewed to the right, with less efficient monitoring of adults, with still limited long-term follow-up beyond 40 years. Therefore, we probably underestimated the solid-tumor risk in CN patients, as many patients, if alive, are no longer followed in hematology centers. Among 103 patients who underwent hematopoietic stem-cell transplantation (HSCT), 76 were long-term survivors. None of them developed solid tumors, which differs strikingly from the high malignancy risk associated with Fanconi anemia post-HSCT. Lastly, the FSCNR also includes and follows patients with idiopathic neutropenia. Among the 232 idiopathic neutropenia patients, followed for a total of 2866 person-years, no malignancy has been observed so far. Conclusion: Our data lead us to advance that CN patients should be considered at risk of developing solid cancers, especially after the age of 30 years. This risk, at first glance, depended on the CN-associated genetic anomaly, with CXCR4 mutation, GATA2, SBDS and ELANE being the most frequent. HSCT was not associated with a higher risk and may, in contrast, be protective. These findings warrant confirmation but represent a compelling reason to prolong follow-up into adulthood of CN patients diagnosed during childhood. No indication was found of a specific high solid-tumor risk associated with idiopathic neutropenia. Reference Donadieu J, Beaupain B, Fenneteau O, Bellanne-Chantelot C.

Giant condyloma acuminata (GCA) is a large condyloma of the anogenital region with a cauliflowerlike appearance. The tumor is extremely rare and is related to human papilloma virus (HPV) infection (HPV type 6 and 11 in 90% of cases).1 The definitive treatment is wide surgical excision, but topical medical treatment can be effective in selected cases.2, 3 Here we report the first case, to our knowledge, of complete regression of vulvar GCA after treatment with topical imiquimod (5% cream) therapy, with no recurrence reported over a 3-year follow-up period. Signed informed consent was obtained from the patient.

Research question Is there any metabolomic evidence of impairment of the cumulus–oocyte complex (COC) microenvironment in the follicular fluid of women with endometriosis? Design A prospective observational study from January to July 2018 at the Angers University Hospital, France. Seventy-nine women undergoing IVF with or without intracytoplasmic sperm injection (ICSI) were included: 39 for endometriosis-related infertility and 40 controls with other causes of infertility. A targeted quantitative metabolomic and lipidomic analysis was performed. Results Patient characteristics (age, body mass index, smoking status, hormonal profile and ovarian reserve markers) were comparable between the endometriosis and the control groups. There was no significant difference in the cumulative FSH dose used for stimulation between the endometriosis and the control groups (2732 versus 2257 IU, respectively). There were no differences in the oocyte maturity rates (72.2% versus 77.7%), or in the fertilization rates in IVF and ICSI (49.4% versus 50.2% and 76.4% versus 68.8%, respectively) between the endometriosis and control groups. Among the 188 metabolites analysed, 150 were accurately measured. Univariate analysis did not reveal any significant modification of metabolite concentrations, and none of the multivariate models discriminated between the two groups of patients, even when the study was restricted to the most severe form of endometriosis. Conclusions No specific metabolomic signature of endometriosis was found in the follicular fluid of women undergoing IVF. These results suggest that there is no microenvironmental impairment of the COC in cases of isolated endometriosis among women with infertility.

Previous studies of component degradation due to electrostatic discharges (ESD) have led to the installation of protective circuits improving the resistance of the components. These ESD protection circuits have led to other degradation phenomena. The sources of degradation are not easily identified. The phenomena involved are slow, but the energy is sufficient to degrade the component. This chapter presents a method for reproducing these phenomena due to electrical overvoltage stresses. The results obtained by simulation and experimentation of metal–oxide–semiconductor field-effect transistor (MOSFET) switching transistors in an inductive magnetic field environment are analyzed.

Purpose To determine the risk of multiple pregnancies (MP) following conversion of in vitro fertilization (IVF) cycles to intrauterine insemination (IUI) when a poor ovarian response (POR) is diagnosed during controlled ovarian stimulation (COS). Methods We undertook a retrospective study in our teaching hospital from January 2012 to December 2017. We included all IVF cycles with POR that were converted to IUI ( ≥ 14 mm and peak estradiol level Results Overall, 205 IVF cycles that were converted to IUI in 128 patients were analyzed. Mean age was 34.1 ± 4.6 years, mean antral follicle count was 11 ± 5.3 and mean AMH was 1.8 ± 2.9 ng/L. The main causes of infertility were unexplained (41 %) (84/205) and diminished ovarian reserve (35 %) (72/205). Of all the cycles converted to IUI, 53 (26 %) had one mature follicle on trigger day, 56 (27 %) had 2, 56 (27 %) had 3, and 40 (20 %) had 4. The live birth rate (LBR) was 7.3 % (15/205), and the miscarriage rate was 28.6 % (6/21). There were 3 twin pregnancies, but no higher order pregnancies; the MP rate was 14.3 % (3/21). There was no significant difference in the MP rate between patients with 1−2 mature follicles and patients with 3−4 mature follicles (18.2 % vs 10 %, p = 0.99, respectively). Conclusion In IVF cycles converted to IUI for poor response, the risk of MP is acceptable (14 %) with no higher order pregnancies, even with 3 or 4 follicles ≥14 mm on trigger day.

International audience; In this study, we demonstrate the capability to detect microscopic stable displacement nature created by proton irradiations with a method based on the discrimination of the three major low frequency noise sources generally observed in semiconductor devices. Low frequency noise measurements are carried out in silicon in-situ phosphorus doped polycrystalline silicon serpentine resistance used as test vehicle. We observe that for the pristine sample, the voltage noise power density can be explained only considering 1/f and thermal noise contribution on the total noise, while for irradiated sample generation recombination noise prevails. Preliminary results on low frequency noise spectroscopy, used as a diagnostic tool in order to identify stable traps created by protons irradiations are presented.

International audience; We have read with great interest the systematic review by Fujii et al. [1] which compares conversion to IUI to continuation with IVF in poor responders (POR) to controlled ovarian stimulation (COS). The authors thoroughly reviewed all studies comparing the two strategies in patients with ≤4 follicles following COS, and concluded that “continuation with IVF offers the best chance at live birth (LB) but not clinical pregnancy when ≥2 follicles develop”. We would like to thank the authors for the extensive review of an important issue that could be helpful for everyday practice, but we believe the results should be interpreted with caution.

The main objective of our study was to analyze the mean time to delivery following cervical ripening with a 10 mg dinoprostone vaginal insert. We performed a retrospective observational study at the level III maternity ward of Angers university hospital. We included all women who had cervical ripening with dinoprostone between January 1st, 2015 and September 30th, 2016. Overall, 405 patients were included, and 59.3% (240/405) were nulliparous. The mean time to delivery was 20h39 min ± 10h49 min. 21% of deliveries (86/405) occurred between midnight and 6 h a.m., and the cesarean section rate was 33% (132/405). Multiple regression analysis showed that nulliparity, overweight (BMI ≥ 25), a closed cervix on initial examination and the absence of premature rupture of membranes (PRM) all significantly increased the mean time to delivery. We developed a mathematical model integrating the aforementioned factors and their impact to help predict the mean time to delivery following cervical ripening with dinoprostone vaginal insert: Y = 961.188–80.346 × parity + 21.437 × BMI–165.263 × cervical dilation–241.759 × PRM. This equation allows obstetricians to calculate a personalized time to delivery for each patient, allowing a precise scheduling of dinoprostone insert placement, and thus improving the organization in busy maternity wards.

Endometriosis is a common condition that causes pain and infertility. It can lead to absenteeism and also to multiple surgeries with a consequent risk of impaired fertility, and constitutes a major public health cost. Despite the existence of numerous national and international guidelines, the management of endometriosis remains suboptimal. To address this issue, the French College of Gynaecologists and Obstetricians (CNGOF) and the Society of Gynaecological and Pelvic Surgery (SCGP) convened a committee of experts tasked with defining the criteria for establishing a system of care networks, headed by Expert Centres, covering all of mainland France and its overseas territories. This document sets out the criteria for the designation of Expert Centres. It will serve as a guide for the authorities concerned, to ensure that the means are provided to adequately manage patients with endometriosis.

Purpose To develop a questionnaire based on patients’ verbal descriptors, to measure the painful symptoms of endometriosis. Methods We performed a two-round modified DELPHI procedure mixing endometriosis patients and physicians to select a set of statements to describe the painful symptoms of endometriosis. Each panelist rated each statement based on diagnosis validity and clarity. The clinicians were experts in endometriosis management selected from various geographic regions in France. Patients were women with surgically confirmed endometriosis who volunteered from a patient association and from the recruitment of the participating physicians. The first round questions were derived from words and phrases in narratives of pain by endometriosis patients. Results Overall, 76 experts were invited, and of these 56 (74%), comprising 33 patients and 23 gynecologists, responded to the first round questionnaire, and 40 (71.4%) to the second round. Among the 48 statements assessed in the first-round questionnaire, 11 were selected after completion of the two round DELPHI procedure. After discussion and rewording of some items, a total of 21 questions were selected during a final face-to-face meeting. The content of the final questionnaire is organized according to four dimensions: (i) spontaneous pelvic pain and dysmenorrhea, (ii) dyspareunia, (iii) painful bowel symptoms, (iv) and other symptoms. We also provide an English (UK) version produced using several steps of translation and back-translation. Conclusions The questionnaire has content validity to measure the subjective experiences of patients with painful endometriosis and can provide a solid basis on which to develop an efficient patient-centered outcome to measure the painful symptoms in therapeutic or in diagnostic studies of endometriosis.

Background To date, there is no consensus on the ideal management strategy of patients with poor ovarian response (POR) to controlled ovarian stimulation (COS) for in vitro fertilization (IVF). Currently, these patients are given the choice of: (1) canceling the cycle; (2) proceeding with COS regardless of the poor response, and performing the oocyte retrieval and transfer of embryos when available; or (3) conversion to an intrauterine insemination (IUI). When the decision to proceed with the COS cycle is taken, it is not clear whether IVF or conversion to IUI is the best choice. If live birth rates were comparable between the two strategies, conversion to IUI would be the better option for poor responders, since it is less invasive and is associated with a lower cost. Methods We designed a non-inferiority, multicentric, randomized controlled trial that will be conducted in 18 French Reproductive Medicine centers. We defined POR as the presence of only two or four mature follicles ≥ 14 mm on ovulation trigger day. Patients with POR will be randomized into two parallel arms: “IVF” and “conversion to IUI.” Our main objective is to compare the efficiency of IVF and conversion to IUI in patients with POR to COS. The primary outcome is the live birth rate, defined as the birth of a living infant after 22 weeks’ gestational age, or weighing ≥ 500 g. One of the secondary objectives is to compare the cost-efficiency of both strategies at 12 months. We will need to include 940 patients (470 in each arm), and the duration of the inclusion period is estimated to be 36 months. Discussion This is the first randomized controlled trial to compare the outcomes of IVF and embryo transfer to conversion to IUI in patients with POR to COS. If our study shows that conversion to IUI is non-inferior to IVF in terms of clinical efficiency and live birth rate, it would confirm IUI as a better alternative for patients, both individually (less invasive and more patient-friendly) and collectively (lower cost).

International audience; In women undergoing controlled ovarian hyperstimulation (COH) for in vitro fertilization (IVF), a poor ovarian response, defined as three of fewer mature follicles, can lead to cancellation of the cycle. However, in women with at least one patent tube and normal semen parameters, conversion to intrauterine insemination (IUI) is considered an option, offering reasonable pregnancy rates at a lower cost and without the complications associated with oocyte retrieval. Studies have shown that in cycles with only one mature follicle, IVF should be canceled. However, in cycles with 2 or 3 mature follicles, patients have the choice between IVF and conversion to IUI. Some studies have shown that IVF is superior to IUI in such cases, whereas other reports failed to find any difference. Most of these studies are retrospective and limited by the presence of several biases and low numbers of cycles, and to this date, there is no consensus on the best approach. We have thus designed a multicenter, randomized non-inferiority study, comparing live birth rates following conversion to IUI or IVF in patients with 2 or 3 mature follicles in COH cycles. Nine hundred and forty patients will be randomized on trigger day to either IVF or conversion to IUI. Our study will also include a medico-economic analysis.; La conversion de la tentative de fécondation in vitro (FIV) en insémination intra-utérine (IIU) peut être une option thérapeutique envisageable en cas de mauvaise réponse à la stimulation ovarienne, sous réserve d’une perméabilité tubaire au moins unilatérale et d’une bonne qualité spermatique. Les avantages d’une conversion en IIU par rapport à une tentative de FIV dans une telle situation seraient multiples: éviter le risque de complications liées à la ponction ovocytaire, éviter le risque d’une ponction blanche et diminuer le coût global de la prise en charge. Après analyse de la littérature, il semblerait qu’il n’y ait pas d’intérêt à réaliser une FIV en présence d’un follicule mature. Le doute subsiste entre la tentative de FIV et la conversion en IIU en présence de 2ou 3follicules matures. En effet, il existe de nombreux biais dans les études ayant retrouvé une supériorité de la FIV par rapport à la conversion en IIU et d’autres études rétrospectives de faible niveau preuve, elles aussi, ont constaté l’absence de différence entre ces 2types de prise en charge. Un projet de recherche multicentrique, randomisée et de non-infériorité doit débuter très prochainement afin de déterminer si les taux de naissances vivantes sont comparables entre les 2stratégies thérapeutiques en présence de 2ou 3follicules matures au moment de la décision du déclenchement de l’ovulation. Une analyse médico-économique sera associée à ce projet devant inclure 940patientes.

Background The frequency of posterior presentations (occiput of the fetus towards the sacrum of the mother) in labor is approximately 20% and, of this, 5% remain posterior until the end of labor. These posterior presentations are associated with higher rates of cesarean section and instrumental delivery. Manual rotation of a posterior position in order to rotate the fetus to an anterior position has been proposed in order to reduce the rate of instrumental fetal delivery. No randomized study has compared the efficacy of this procedure to expectant management. We therefore propose a monocentric, interventional, randomized, prospective study to show the superiority of vaginal delivery rates using the manual rotation of the posterior position at full dilation over expectant management. Methods Ultrasound imaging of the presentation will be performed at full dilation on all the singleton pregnancies for which a clinical suspicion of a posterior position was raised at more than 37 weeks’ gestation (WG). In the event of an ultrasound confirming a posterior position, the patient will be randomized into an experimental group (manual rotation) or a control group (expectative management with no rotation). For a power of 90% and the hypothesis that vaginal deliveries will increase by 20%, (10% of patients lost to follow-up) 238 patients will need to be included in the study. The primary endpoint will be the rate of spontaneous vaginal deliveries (expected rate without rotation: 60%). The secondary endpoints will be the rate of fetal extractions (cesarean or instrumental) and the maternal and fetal morbidity and mortality rates. The intent-to-treat study will be conducted over 24 months. Recruitment started in February 2017. To achieve the primary objective, we will perform a test comparing the number of spontaneous vaginal deliveries in the two groups using Pearson’s chi-squared test (provided that the conditions for using this test are satisfactory in terms of numbers). In the event that this test cannot be performed, we will use Fisher’s exact test. Discussion Given that the efficacy of manual rotation has not been proven with a high level of evidence, the practice of this technique is not systematically recommended by scholarly societies and is, therefore, rarely performed by obstetric gynecologists. If our hypothesis regarding the superiority of manual rotation is confirmed, our study will help change delivery practices in cases of posterior fetal position. An increase in the rates of vaginal delivery will help decrease the short- and long-term rates of morbidity and mortality following cesarean section. Manual rotation is a simple and effective method with a success rate of almost 90%. Several preliminary studies have shown that manual rotation is associated with reduced rates for fetal extraction and maternal complications: Shaffer has shown that the cesarean section rate is lower in patients for whom a manual rotation is performed successfully (2%) with a 9% rate of cesarean sections when manual rotation is performed versus 41% when it is not performed. Le Ray has shown that manual rotation significantly reduces vaginal delivery rates via fetal extraction (23.2% vs 38.7%, p < 0.01). However, manual rotation is not systematically performed due to the absence of proof of its efficacy in retrospective studies and quasi-experimental before/after studies.

Objective To compare neonatal morbidity and mortality rates in preterm singleton breech deliveries from 26 0/7 to 29 6/7 weeks of gestation in centers with a policy of either planned vaginal delivery (PVD) or planned cesarean delivery (PCD). Study design Women with preterm singleton breech deliveries occurring after preterm labor or preterm premature rupture of membranes (pPROM) were identified from the databases of five perinatal centers and classified as PVD or PCD according to the center's management policy. The independent association between planned mode of delivery and the risk of neonatal hospital death or morbidity was tested and quantified with ORs through two-level multivariable logistic regression modeling. Results Of 142 782 deliveries during the study period, 626 (0.4%) were singletons in breech presentation from 26 0/7 to 29 6/7 weeks of gestation: after exclusions, 130 were in the PVD group and 173 in the PCD group. Severe newborn morbidity was similar in the two groups. Newborn mortality was 12% in the PCD group and 16% in the PVD group. Three neonates (1.7%, 95% CI: 0.34–5.0) died from head entrapment after vaginal delivery in the PVD group. Nonetheless, the policy of PVD was not associated with increased risks of neonatal death (aOR: 1.01, 95% CI: 0.33–2.92) or severe morbidity. Conclusion Risks of mortality and severe morbidity in preterm breech were not increased by a policy of vaginal delivery. Head entrapment leading to death is however possible in cases of vaginal delivery but its rarity should be balanced with the maternal consequences of early preterm cesarean delivery.

Sensors and effectors of all sorts are becoming more and more integrated in human everyday lives. Systems built on top of these sensors/effectors adding a cybernetic component in order to assist humans in their everyday life are called Cyber-Physical Systems. Such systems may be difficult to analyze and design, as they are composed of numerous interacting entities immerged in a dynamic and partially predictable environment. The goal of this paper is to propose a methodological approach based upon Multi-Agent Systems that has two main advantages. First it allows the decomposition of CPS structural and behavioral complexity and, second, it enables a prototyping by simulation approach that eases system validation.

International audience; A bended and straight coplanar waveguides are modeled by using HFSS 3D electromagnetic software. The behavior of bend CPW is described by matrix calculations in order to show the effect of the parasitic even mode on the propagation of a signal. A comparison is done in this article with several works done before to show that there is a significant error when using bended CPW standard instead of straight ones in calibration.

In this paper, hot carrier injection mechanism effect on DC and RF performances of n-channel transistors of a 0.25μ CMOS technology in function of gate-source voltage are investigated using an in-house reliability simulation tool. The study concludes that after 10 years of DC stress, transistors present about 50% decrease of linear drain current, a 40% decrease of saturation drain current, as well as a reduction of 95% in transconductance and 90% in the transition frequency. Last but not least, the threshold voltage is increased by 0.55 V after stress. Predicted results are compared to hot carrier model in order to validate the accuracy of the simulator. Reliability analysis is extended to circuits' degradation under hot carrier mechanism to raise awareness of circuit-level reliability simulation interest. A comparison between two typical current mirrors circuits behavior after hot carrier stress has been made.

A reliability study under high RF power stressing was conducted on two SiGe cascode Low Noise Amplifiers (LNA) using an in-house reliability tool. The first LNA was stressed at 19 dBm of RF power during 600 hours. Obtained results (relative degradation values in dB) showed a decrease of 11% in the small-signal gain (S 21 ), while the second was stressed at 20 dBm of RF power during non-stop 600 hours. The results, under these conditions, showed a decrease of 12% in the S 21 and an increase of 13.8% in the Noise Figure (NF). All predictive degradation simulations were compared to measurements demonstrating a satisfactory agreement.

STUDY QUESTION Does ovarian ageing increase the number of heteroplasmic mitochondrial DNA (mtDNA) point mutations in oocytes? SUMMARY ANSWER Our results suggest that oocytes are not subject to the accumulation of mtDNA point mutations during ovarian ageing. WHAT IS KNOWN ALREADY Ageing is associated with the alteration of mtDNA integrity in various tissues. Primary oocytes, present in the ovary since embryonic life, may accumulate mtDNA mutations during the process of ovarian ageing. STUDY DESIGN, SIZE, DURATION This was an observational study of 53 immature oocyte-cumulus complexes retrieved from 35 women undergoing IVF at the University Hospital of Angers, France, from March 2013 to March 2014. The women were classified in two groups, one including 19 women showing signs of ovarian ageing objectified by a diminished ovarian reserve (DOR), and the other, including 16 women with a normal ovarian reserve (NOR), which served as a control group. PARTICIPANTS/MATERIALS, SETTING, METHODS mtDNA was extracted from isolated oocytes, and from their corresponding cumulus cells (CCs) considered as a somatic cell compartment. The average mtDNA content of each sample was assessed by using a quantitative real-time PCR technique. Deep sequencing was performed using the Ion Torrent Proton for Next-Generation Sequencing. Signal processing and base calling were done by the embedded pre-processing pipeline and the variants were analyzed using an in-house workflow. The distribution of the different variants between DOR and NOR patients, on one hand, and oocyte and CCs, on the other, was analyzed with the generalized mixed linear model to take into account the cluster of cells belonging to a given mother. MAIN RESULTS AND THE ROLE OF CHANCE There were no significant differences between the numbers of mtDNA variants between the DOR and the NOR patients, either in the oocytes (P = 0.867) or in the surrounding CCs (P = 0.154). There were also no differences in terms of variants with potential functional consequences. De-novo mtDNA variants were found in 28% of the oocytes and in 66% of the CCs with the mean number of variants being significantly different (respectively 0.321, SD = 0.547 and 1.075, SD = 1.158) (P < 0.0001). Variants with a potential functional consequence were also overrepresented in CCs compared with oocytes (P = 0.0019). LARGE SCALE DATA N/A. LIMITATIONS, REASONS FOR CAUTION Limitations may be due to the use of immature oocytes discarded during the assisted reproductive technology procedure, the small size of the sample, and the high-throughput sequencing technology that might not have detected heteroplasmy levels lower than 2%. WIDER IMPLICATIONS OF THE FINDINGS The alteration of mtDNA integrity in oocytes during ovarian ageing is a recurring question to which our pilot study suggests a reassuring answer.

International audience; This paper teaches the way to achieve an optimum substrate isolation in RF switch design thanks to Deep Trenches Isolation (DTI). The role of Deep Trench Isolation in substrate coupling around active blocks is analysed in link to its ability to break the conductive buried layers in the substrate. Then, an accurate modelling approach based on quasi-static approach developed for inhomogeneous substrate is investigated. The efficiency of this methodology is first demonstrated thanks to a comparison with a standard numerical method based on FEM (Finite Element Method). Then, experiments data are provided to support this theoretical analysis. The methodology is fully integrated in a commercial design flow and offers a perfect trade-off between accuracy and run time simulation. From available test data on single device and a full SP3T, a correlation better than 0.1dB is obtained between simulation and measurement up to 8 GHz.

Microelectronics are literally everywhere within our modern everyday lives. They are present in many fields including transport, medicine, telecommunications etc. All of these applications rely on the use of the same basic unit: the MOS transistor (metal oxide semiconductor field effect transistor) and / or the bipolar transistor.

Objective The objective of this multicenter, randomized study was to investigate the efficacy of the hydrophilic resorbable film PREVADH™ in preventing postoperative adhesions following myomectomy. Study design Women scheduled for laparotomic myomectomy with intramural and/or subserous myomas of >60 mm in diameter, and who wished to preserve fertility, were eligible. Patients were randomized immediately prior to abdominal wall closure to receive either hydrophilic resorbable film applied directly to the incisions (P-Group, n = 33) or 500 mL Ringer's lactate solution instilled into the pelvic cavity (R-Group, n = 28). Incidence, severity, and extent of postoperative adhesions to the uterine incisions and adnexal and abdominopelvic adhesions were assessed during second-look laparoscopy 10–20 weeks after the initial surgery. Unedited videotapes of this second-look procedure were reviewed by two blinded independent surgeons. Results Fifty-four patients (P-Group, n = 28; R-Group, n = 26) underwent second-look laparoscopy. Significantly fewer P-Group patients developed adhesions to uterine incisions than R-Group patients (43% vs. 92%, P = 0.001). Adhesions, which were confirmed by independent reviewers, were found in significantly fewer P-Group sites than R-Group sites (29% vs. 76%, P = 0.001). No serious adverse events related to the barriers used or adhesion-related complications were reported in either group. Conclusion The hydrophilic resorbable anti-adhesion film PREVADH™ significantly reduced adhesion incidence and severity after laparotomic myomectomy.
