A novel RYR1 variant in an infant with a unique fetal presentation of central core disease.

Ryanodine receptor type 1-related disorder (RYR1-RD) is the most common subgroup of congenital myopathies with a wide phenotypic spectrum ranging from mild hypotonia to lethal fetal akinesia. Genetic testing for myopathies is imperative as the diagnosis informs counseling regarding prognosis and recurrence risk, treatment options, monitoring, and clinical management. However, diagnostic challenges exist as current options are limited to clinical suspicion prompting testing including: single gene sequencing or familial variant testing, multi-gene panels, exome, genome sequencing, and invasive testing including muscle biopsy. The timing of diagnosis is of great importance due to the association of RYR1-RD with malignant hyperthermia (MH). MH is a hypermetabolic crisis that occurs secondary to excessive calcium release in muscles, leading to systemic effects that can progress to shock and death if unrecognized. Given the association of MH with pathogenic variants in RYR1, a diagnosis of RYR1-RD necessitates an awareness of medical team to avoid potentially triggering agents. We describe a case of a unique fetal presentation with bilateral diaphragmatic eventrations who had respiratory failure, dysmorphic facial features, and profound global hypotonia in the neonatal period. The diagnosis was made at several months of age, had direct implications on her clinical care related to anticipated need to long-term ventilator support, and ultimately death secondary an arrhythmia as a result of suspected MH. Our report reinforces the importance of having high suspicion for a genetic syndrome and pursuing early, rapid exome or genome sequencing as first line testing in critically ill neonatal intensive care unit patients and further evaluating the pathogenicity of a variant of uncertain significance in the setting of a myopathic phenotype.

The success of vaginal birth by use of trans-labial ultrasound plus vaginal examination and vaginal examination only in pregnant women with labor induction: a comparative study.

BACKGROUND: Predicting the success of vaginal delivery is an important issue in preventing adverse maternal and neonatal outcomes. Thus, this study aimed to compare the success rate of vaginal birth by using trans-labial ultrasound and vaginal examination, and vaginal examination only in pregnant women with labor induction. METHODS: This was a comparative study including 392 eligible pregnant women with labor induction attending to a teaching hospital affiliated with Iran University of Medical Sciences from April to October 2018 in Tehran, Iran. Women were randomly assigned to two groups; the trans-labial ultrasound plus vaginal examination (group A), and the vaginal examination only (group B). Women were included in the study if they satisfied the following criteria: singleton pregnancy, 37 to 42 weeks of gestational age, fetal head presentation, a living fetus with no abnormalities, uncomplicated pregnancy, and no previous cesarean section or any uterine surgery. We used a partograph for both groups to assess the fetal head position and the fetal head station. In group 1, the Angle of Progression (AoP) and Rotation Angle (RA) were also assessed. Finally, the success and progression of vaginal delivery in two groups were compared by predicting the duration of delivery and mode of delivery. RESULTS: The findings showed that 8.68% of women in the trans-labial plus vaginal examination group delivered by cesarean section, while 6.13% in the vaginal examination only group delivered by cesarean section (P = 0.55). In women with cesarean section in positive fetal head stations, Angle of Progression (AoP) was significantly decreased ranging from 90 to 135 degrees compared to women who delivered vaginally (135-180 degrees; P <  0.001). In addition, the Rotation Angle (RA) was significantly decreased in women with cesarean section ranging from 0 to 30 degrees compared to women who delivered vaginally (60-90degrees; P <  0.001). Further analysis indicated that a higher risk of cesarean section was associated with vaginal examination only as compared to trans-labial ultrasound plus vaginal examination (HR: 8.65, P <  0.001). CONCLUSION: Angle of Progression (AoP) and Rotation Angle (RA) indexes might be useful parameters to predict labor progression and successful vaginal delivery among women undergoing labor induction.

Fetal Presentation of Walker-Warburg Syndrome with Compound Heterozygous POMT2 Missense Mutations.

Background: Walker-Warburg syndrome (WWS) (OMIM #236670) is an autosomal recessive disorder characterized by congenital muscular dystrophy, hydrocephalus, cobblestone lissencephaly, and retinal dysplasia. The main genes involved are: POMT1, POMT2, POMGNT1, FKTN, LARGE1, and FKRP. Case report: We present a fetus with WWS showing at ultrasound severe triventricular hydrocephalus. Pregnancy was legally terminated at 21 weeks +2 days of gestation. In vivo and postmortem magnetic resonance revealed corpus callosum agenesis and cerebellar hypoplasia. Cobblestone lissencephaly was observed at post-mortem. Next generation sequencing (NGS) of 193 genes, performed on fetal DNA extracted from amniocytes, detected two heterozygous mutations in the POMT2 gene. The c.1238G > C p.(Arg413Pro) mutation was paternally inherited and is known to be pathogenic. The c.553G > A p.(Gly185Arg) mutation was maternally inherited and has not been previously described. Conclusion: Compound heterozygous mutations in the POMT2 gene caused a severe cerebral fetal phenotype diagnosed prenatally at midgestation allowing therapeutic pregnancy termination.

Congenital orbital teratoma: A case report with foetal presentation.

Congenital orbital teratomas are rare entities with few case reports detailing their prenatal and perinatal imaging features. We present the case of a congenital orbital teratoma initially detected as cystic lesion on prenatal ultrasound, with foetal and postnatal imaging showing evolution of characteristic MRI appearances. Knowledge of these appearances and the ability to diagnose these rare entities in foetal life can aid management and operative planning in the immediate postnatal period.

Fetal presentation of chondrodysplasia with joint dislocations, GPAPP type, caused by novel biallelic IMPAD1 variants.

Biallelic IMPAD1 pathogenic variants leads to deficiency of GPAPP (Golgi 3-prime phosphoadenosine 5-prime phosphate 3-prime phosphatase) protein and clinically causes chondrodysplasia, which is characterized by short stature with short limbs, craniofacial malformations, cleft palate, hand and foot anomalies, and various radiographic skeletal manifestations. Here we describe prenatal presentation of GPAPP deficiency caused by novel biallelic pathogenic variants, 2 base pair duplication in exon 2 of IMAPD1 gene in a patient of Asian-Indian origin. Further we report on diagnostic clues of prenatal presentation of GPAPP deficiency through ultrasonography, fetal MRI, and postmortem findings. We also provide evidence of pathophysiology of underlying GPAPP deficiency in the form of disorganization and dysplastic chondrocytes and reduced sulfation of glycoproteins through histopathology of cartilage similar to that described in mice IMPAD1 homozygous mutant model.

Abstract Objective To develop an algorithm for perineal assessment in childbirth care and assess its applicability and accuracy using a decision support system prototype. Methods This is applied research of technological development, consisting of the construction of an algorithm, assessment by professionals with expertise in the area, creation of a Decision Support System prototype using online tools and assessment of its applicability and accuracy during care for 305 childbirths performed by nurses. Data were analyzed using descriptive statistics, chi-square and Fisher's exact tests, in addition to the Kappa coefficient to assess the agreement between the procedure indicated by the system and that performed by professionals. Results There was agreement between the algorithm's suggestion and professional decision in 93.1% of childbirths. In 6.9%, professionals decided opposite paths to the recommended one. The professionals who chose to follow the algorithm's suggestion had perineal integrity or the occurrence of first-degree tear as an outcome. Those who chose not to follow the recommendation had second- or third-degree tears in 28.6% of parturient women. In the accuracy analysis, the algorithm suggested that episiotomy should be performed in 45 of the 305 assisted childbirths. There was an association between divergences in conduct and the number of adverse events (p=0.001). Conclusion The algorithm proved to be a useful tool for perineal assessment in childbirth care.

Mode of delivery and adverse short- and long-term outcomes in vertex-presenting very preterm born infants: a European population-based prospective cohort study.

OBJECTIVES: To compare mortality, morbidity and neurodevelopment by mode of delivery (MOD) for very preterm births with low prelabour risk of caesarean section (CS). METHODS: The study was a population-based prospective cohort study in 19 regions in 11 European countries. Multivariable mixed effects models and weighted propensity score models were used to estimate adjusted odds ratios (aOR) by observed MOD and the unit's policy regarding MOD. Population: Singleton vertex-presenting live births at 24 + 0 to 31 + 6 weeks of gestation without serious congenital anomalies, preeclampsia, HELLP or eclampsia, antenatal detection of growth restriction and prelabour CS for fetal or maternal indications. RESULTS: Main outcome measures: A composite of in-hospital mortality and intraventricular haemorrhage (grade III/IV) or periventricular leukomalacia. Secondary outcomes were components of the primary outcome, 5 min Apgar score <7 and moderate to severe neurodevelopmental impairment at two years of corrected age. The rate of CS was 29.6% but varied greatly between countries (8.0-52.6%). MOD was not associated with the primary outcome (aOR for CS 0.99; 95% confidence interval [CI] 0.65-1.50) when comparing units with a systematic policy of CS or no policy of MOD to units with a policy of vaginal delivery (aOR 0.88; 95% CI 0.59-1.32). No association was observed for two-year neurodevelopment impairment for CS (aOR 1.15; 95% CI 0.66-2.01) or unit policies (aOR 1.04; 95% CI 0.63-1.70). CONCLUSIONS: Among singleton vertex-presenting live births without medical complications requiring a CS at 24 + 0 to 31 + 6 weeks of gestation, CS was not associated with improved neonatal or long-term outcomes.

O imaginário materno sobre os partos cesáreo e vaginal / The maternal imagery on cesarean and vaginal deliveries / El imaginario materno sobre los partos cesáreo y vaginal

Este artigo objetivou compreender o imaginário materno sobre os partos cesáreo e vaginal. Para isso, utilizou-se de revisão da literatura e entrevista semi-estruturada com quatro gestantes participantes do Grupo de Gestantes de uma maternidade pública de Goiânia. Os dados foram tratados pela análise de conteúdo e mostraram uma visão mais positiva sobre a via vaginal em contraposição ao cirúrgico, que se relacionou à intercorrência. Além disso, o imaginário das participantes se mostrou em grande parte permeado por sentimentos e ideias negativas como medo, ansiedade e preocupação sobre ambos os partos. As principais informações que baseiam as concepções das gestantes partem das experiências passadas por outras mulheres e não dos conhecimentos médicos, de modo que são constituídas principalmente por histórias de violência, dor e desrespeito. Conclui-se que o imaginário materno, formado a partir do contexto atual de saúde, compreende o parto como um evento temido, que se desejaria evitar. Percebe-se que a assistência em saúde prestada hoje ainda é insuficiente por não orientar corretamente a mulher e dificultar que ela domine a cena do parto, o que a deixa à margem da humanização. Ademais, o cuidado terapêutico voltado à mulher não se pauta na opinião e nos sentimentos da paciente para embasar sua atuação, o que de certa forma contribui para manutenção do imaginário negativo sobre parto e demanda maior empenho em relação às práticas e à educação permanente.(AU)

This article sought to understand the maternal imaginary on cesarean and vaginal deliveries. Data were collected by means of a literature review and semi-structured interviews conducted with four pregnant women, participants of the Group of Pregnant Women in a public maternity hospital in Goiânia, and treated by content analysis. The results indicate that mothers tend to have a more positive view of the vaginal route, associating surgical deliveries to pregnancy complications. Being mostly informed by the experiences of other women rather than by medical knowledge, and thus influenced by stories of violence, pain, and disrespect, the imagery of participants proved to be largely permeated by negative feelings and ideas about both types of birth, such as fear, anxiety, and concern. Thus, in the current health context, the maternal imaginary understands childbirth as a feared event, which one would want to avoid. This finding highlights the inappropriate healthcare provided to pregnant women, failing in properly guiding and preventing them from controlling the delivery scene, being left on the margins of humanization. This is because the therapeutic care aimed at women is not based on the patient's opinion and feelings, thus contributing to the maintenance of this negative imagery about childbirth and demanding greater commitment in relation to practices and permanent education.(AU)

Este artículo tuvo como objetivo comprender el imaginario materno sobre cesáreas y partos vaginales. Para eso, se hace una revisión de la literatura y una entrevista semiestructurada con cuatro mujeres embarazadas, participantes del Grupo de Mujeres Embarazadas en un hospital público de maternidad en Goiânia (Brasil). En los datos obtenidos se aplicaron análisis de contenido en que se reveló una visión más positiva de la ruta vaginal en comparación con la quirúrgica relacionada con la complicación. Además, en el imaginario de las participantes figuran sentimientos e ideas negativas como el miedo, la ansiedad y la preocupación por ambos tipos de parto. La información principal que respalda las concepciones de las mujeres embarazadas proviene de las experiencias transmitidas por otras mujeres, y no del conocimiento médico, que consiste principalmente en historias de violencia, dolor y falta de respeto. Se concluye que el imaginario materno, formado a partir del contexto de salud actual, entiende el parto como un evento temido, que hubieran querido evitar. Está claro que la atención médica brindada hoy en día aún es insuficiente porque no guía correctamente a las mujeres y les impide dominar la escena del parto, dejándolas al margen de la humanización. Se percibe que la atención terapéutica dirigida a las mujeres no se basa en su opinión y sentimiento para respaldar el desempeño, lo que de cierta manera contribuye al mantenimiento de esta imagen negativa sobre el parto y exige un mayor compromiso en relación con las prácticas y la educación permanente.(AU)

Pattern of Live Births in Rio de Janeiro State, Brazil, According to Robson Groups and the Kotelchuck Index Classification - 2015/2016.

OBJECTIVE: To investigate the patterns of hospital births in the state of Rio de Janeiro (RJ), Brazil, between 2015 and 2016; considering the classification of obstetric characteristics proposed by Robson and the prenatal care index proposed by Kotelchuck. METHODS: Data obtained from the Information System on Live Births of the Informatics Department of the Brazilian Unified Health System (SINASC/DATASUS, in the Portuguese acronym) databases were used to group pregnant women relatively to the Robson classification. A descriptive analysis was performed for each Robson group, considering the variables: maternal age, marital status, schooling, parity, Kotelchuck prenatal adequacy index and gestational age. A logistic model estimated odds ratios (ORs) for cesarean sections (C-sections), considering the aforementioned variables. RESULTS: Out of the 456,089 live births in Rio de Janeiro state between 2015 and 2016, 391,961 records were retained, 60.3% of which were C-sections. Most pregnant women (58.6%) were classified in groups 5, 2 or 3. The percentage of C-sections in the Robson groups 1, 2, 3, 4, 5 and 8 was much higher than expected. Prenatal care proved to be inadequate for women who subsequently had a vaginal delivery, had an unfavorable family structure and a lower socioeconomic status (mothers without partners and with lower schooling), compared with those undergoing cesarean delivery. For a same Robson group, the chance of C-section increases when maternal age rises (OR = 3.33 for 41-45 years old), there is the presence of a partner (OR = 1.81) and prenatal care improves (OR = 3.19 for "adequate plus"). CONCLUSION: There are indications that in the state of RJ, from 2015 to 2016, many cesarean deliveries were performed due to nonclinical factors.

OBJETIVO: Investigar os padrões dos partos hospitalares no estado do Rio de Janeiro (RJ), Brasil, entre 2015 e 2016, considerando a classificação de características obstétricas de Robson e a dos cuidados pré-natais proposta por Kotelchuck. MéTODOS: Dados sistema de informações sobre nascidos vivos (SINASC) do departamento de informática do sistema único de saúde (DATASUS) foram utilizados para agrupar gestantes relativamente à classificação de Robson. Foi efetuada uma análise descritiva para cada grupo de Robson, considerando-se as variáveis idade materna, estado civil, escolaridade, paridade, o índice de Kotelchuck de adequação do pré-natal e a idade gestacional. Também foi realizado o cálculo de razão de chances (RC) para parto cesáreo, considerando-se um modelo logístico. RESULTADOS: Dos 456.089 nascimentos vivos ocorridos no RJ de 2015 a 2016, foram incluídos 391.961 registros, sendo 60,3% cesáreas, com maioria de gestantes (58,6%) nos grupos 5, 2 ou 3. O percentual de cesáreas nos grupos 1, 2, 3, 4, 5 e 8 foi bem superior ao sugerido pela literatura. Para gestantes de um mesmo grupo (controladas as demais características), a chance de cesárea se eleva quando aumenta a idade materna (RC = 3,33 para 41­45 anos), existe a presença de um companheiro (RC = 1,81), o nível de escolaridade é maior (RC = 3,11 para ≥ 12 anos) e o pré-natal é mais cuidadoso (RC = 3,19 para "adequado plus"). CONCLUSãO: Há indícios que no RJ, de 2015 a 2016, muitos partos cesáreos foram realizados sob influência de fatores extraclínicos.

Difficult caesarean section: A literature review.

BACKGROUND: Caesarean section (CS) is usually perceived as a simple and safe alternative to natural birth, but in some instances can be technically difficult with consequent health hazards for both the mother and the fetus. We have proposed an evidence-based literature review of the most common difficult CS scenarios, with the aim to provide useful information about their management, possible prevention and resolution of complications. METHODS: We identified articles through a reserch in PubMed, Scopus, Web of Science and Ovid MEDLINE for studies published between 1979 and 2019. We included the best available evidence, such as RCTs, non-randomised controlled clinical trials, case-control studies, cohort studies, and case series. About sixty articles were included in this review, four hundred and thirty-six were excluded after reviewing the title or abstract or because they weren't in English. FINDINGS: The possible causes of "difficult" caesarean sections were divided into four categories: difficult access to the lower uterine segment; complicated fetal extraction, laceration or organ damage and abnormal placentation. CONCLUSIONS: Knowing in advance the potential technical difficulties and resulting risks allows the surgeon to plan appropriate strategies.

Reproductive Implications and Management of Congenital Uterine Anomalies: Scientific Impact Paper No. 62 November 2019.

Congenital uterine anomalies (CUAs) are malformations of the womb that develop during fetal life. When a baby girl is in her mother's womb, her womb develops as two separate halves from two tubular structures called 'müllerian ducts', which fuse together before she is born. Abnormalities that occur during the baby's development can be variable from complete absence of a womb through to more subtle anomalies, which are classified into specific categories. While conventional ultrasound is good in screening for CUAs, 3D ultrasound is used to confirm a diagnosis. If a complex womb abnormality is suspected, MRI scanning may also be used, with a combination of laparoscopy in which a camera is inserted into the cavity of the abdomen, and hysteroscopy, when the camera is placed in the womb cavity. As there can be a link between CUAs and abnormalities of the kidney and bladder, scans of these organs are also usually requested. Although CUAs are present at birth, adult women typically do not have any symptoms, although some may experience painful periods. Most cases of CUA do not cause a woman to have difficulty in becoming pregnant and the outcome of pregnancy is good. However, these womb anomalies are often discovered during investigations for infertility or miscarriage. Moreover, depending upon the type and severity of CUA, there may be increased risk of first and second trimester miscarriages, preterm birth, poor growth of the baby in the mother's womb (fetal growth restriction), pre-eclampsia and difficult positioning of the baby for birth (fetal malpresentation). Surgical treatment is only recommended to a woman who has had recurrent miscarriages and has a septate uterus, i.e., the womb cavity is divided by a partition. In this case, surgery may improve her chances for a successful pregnancy, although the risks of surgery, especially scarring of the womb should be considered. However, further evidence from randomised controlled trials are required to provide conclusive evidence-based recommendations for surgical treatment for septate uterus. Surgical treatment for other types of CUAs is not usually recommended as the risks outweigh potential benefits, and evidence for any benefits is lacking. Women with CUAs may be at an increased risk of preterm birth even after surgical treatment for a septate uterus. These women, if suspected to be at an increased risk of preterm birth based on the severity of CUA, should be followed up using an appropriate protocol for preterm birth as outlined in UK Preterm Birth Clinical Network Guidance.1 >.

Adverse obstetric outcomes among female childhood and adolescent cancer survivors in Sweden: A population-based matched cohort study.

INTRODUCTION: Cancer treatment during childhood may lead to late adverse effects, such as reduced musculoskeletal development or vascular, endocrine and pulmonary dysfunction, which in turn may have an adverse effect on later pregnancy and childbirth. The aim of the present study was to investigate pregnancy and obstetric outcomes as well as the offspring's health among childhood and adolescent female cancer survivors. MATERIAL AND METHODS: This register-based study included all women born between 1973 and 1977 diagnosed with cancer in childhood or adolescence (age <21), as well as an age-matched comparison group. A total of 278 female cancer survivors with their first childbirth were included in the study, together with 829 age-matched individuals from the general population. Logistic regression and analysis of variance were used to investigate associations between having been treated for cancer and the outcome variables, adjusting for maternal age, nicotine use and comorbidity. RESULTS: Survivors were more likely to have preeclampsia (adjusted odds ratio [aOR] 3.46, 95% confidence interval [CI] 1.58 to 7.56), undergo induction of labor (aOR 1.66, 95% CI 1.05 to 2.62), suffer labor dystocia (primary labor dystocia aOR 3.54, 95% CI 1.51 to 8.34 and secondary labor dystocia aOR 2.43, 95% CI 1.37 to 4.31), malpresentation of fetus (aOR 2.02, 95% CI 1.12 to 3.65) and imminent fetal asphyxia (aOR 2.55, 95% CI 1.49 to 4.39). In addition, deliveries among survivors were more likely to end with vacuum extraction (aOR 2.53, 95% CI 1.44 to 4.47), with higher risk of clitoral lacerations (aOR 2.18, 95% CI 1.47 to 3.23) and anal sphincter injury (aOR 2.76, 95% CI 1.14 to 6.70) and emergency cesarean section (aOR 2.34 95% CI 1.39 to 3.95). Survivors used pain-reliving methods to a higher extent compared with the comparison group. There was no increased risk of neonate diagnoses and malformations. The results showed that survivors who had been diagnosed with cancer when they were younger than 14 had an increased risk of adverse obstetric outcomes. CONCLUSIONS: The study demonstrates increased risk of pregnancy and childbirth complications among childhood and adolescent cancer survivors. There is a need to optimize perinatal care, especially among survivors who were younger than 14 at time of diagnosis.

"Strategies to increase the accuracy and safety of OVD" (Clinical assessment skills and role of ultrasound, simulation training and new technologies to enhance instrument application).

Operative vaginal delivery (OVD) is commonly performed in the UK and Ireland. With skillful practice, the risks to mothers and babies are low. Caesarean section at full dilatation, particularly after failed OVD, can be more hazardous for mothers and babies. It is important to maintain and develop skills in OVD in order to provide it as a safe delivery option when the benefits outweigh the risks. As ultrasound machines have become more readily available on the labour ward, ultrasound assessment has been used to help clinicians diagnose the fetal head position and station, and also to try predict the success of the delivery. Simulation training has successfully been used in the setting of obstetric emergencies and is being developed to teach both technical and communication skills in OVD in order to improve maternal and neonatal outcomes. In this chapter we will discuss strategies to improve the accuracy and safety of OVD in more details.

Women's recommendations: vacuum extraction or caesarean section for prolonged second stage of labour, a prospective cohort study in Uganda.

OBJECTIVES: To investigate what women who have experienced vacuum extraction or second stage caesarean section (CS) would recommend as mode of birth in case of prolonged second stage of labour. METHODS: A prospective cohort study was conducted in a tertiary referral hospital in Uganda. Between November 2014 and July 2015, women with a term singleton in vertex presentation who had undergone vacuum extraction or second stage CS were included. The first day and 6 months after birth women were asked what they would recommend to a friend: vacuum extraction or CS and why. Outcome measures were: proportions of women choosing vacuum extraction vs. CS and reasons for choosing this mode of birth. RESULTS: The first day after birth, 293/318 (92.1%) women who had undergone vacuum extraction and 176/409 (43.0%) women who had undergone CS recommended vacuum extraction. Of women who had given birth by CS in a previous pregnancy and had vacuum extraction this time, 31/32 (96.9%) recommended vacuum extraction. Six months after birth findings were comparable. Less pain, shorter recovery period, avoiding surgery and the presumed relative safety of vacuum extraction to the mother were the main reasons for preferring vacuum extraction. Main reasons to opt for CS were having experienced CS without problems, CS presumed as being safer for the neonate, CS being the only option the woman was aware of, as well as the concern that vacuum extraction would fail. CONCLUSIONS: Most women would recommend vacuum extraction over CS in case of prolonged second stage of labour.

OBJECTIFS: Investiguer ce que les femmes qui ont subi une extraction sous vide ou une césarienne au second stade du travail recommanderaient comme mode d'accouchement en cas de second stade prolongé du travail. MÉTHODES: Une étude de cohorte prospective a été menée dans un hôpital de référence tertiaire en Ouganda. Entre novembre 2014 et juillet 2015, les femmes avec un singleton à terme en présentation de vertex ayant subi une extraction sous vide ou une césarienne de second stade ont été incluses. Le premier jour et six mois après la naissance, on a demandé aux femmes ce qu'elles recommanderaient à une amie: l'extraction sous vide ou la césarienne et pourquoi. Les résultats mesurés étaient: les proportions de femmes choisissant l'extraction sous vide par rapport à la césarienne et les raisons de choisir ce mode d'accouchement. RÉSULTATS: Le premier jour après l'accouchement, 293/318 femmes (92,1%) ayant subi une extraction sous vide et 176/409 (43,0%) femmes ayant subi une césarienne ont recommandé l'extraction sous vide. Parmi les femmes qui avaient accouché par césarienne dans une grossesse précédente et qui avaient eu une extraction sous vide cette fois-ci, 31/32 (96,9%) ont recommandé l'extraction sous vide. Six mois après la naissance, les résultats étaient comparables. Moins de douleur, une période de convalescence plus courte, l'évitement de la chirurgie et la sécurité relative présumée de l'extraction sous vide pour la mère étaient les principales raisons de préférer l'extraction sous vide. Les principales raisons d'opter pour la césarienne étaient l'expérience d'avoir subi une césarienne sans problèmes, la césarienne étant supposée être plus sûre pour le nouveau-né, la césarienne étant la seule option dont la femme était au courant, ainsi que la crainte d'un éventuel échec de l'extraction sous vide. CONCLUSIONS: La plupart des femmes recommanderaient l'extraction sous vide plutôt que la césarienne en cas de second stade prolongé du travail.

Evaluation of a Quality Improvement Intervention to Increase Vaginal Birth for Twins.

OBJECTIVE: To evaluate whether there was an association between the systematic promotion of twin vaginal delivery and an increase in the rates of twin vaginal birth. METHODS: We conducted a retrospective cohort study. We implemented a quality improvement initiative promoting twin vaginal delivery at an academic tertiary care center in 2013. The program included a needs assessment, simulation of vaginal twin delivery, online educational material, and the expansion of a dedicated twin clinic. We analyzed rates of twin vaginal birth in pregnancies at or beyond 24 weeks of gestation without a contraindication to labor, prior uterine surgery, or a demise or lethal anomaly of either twin. Using linear regression, we calculated annual adjusted rates of twin vaginal birth from 2010 to 2015 and in the 3 years before and after our intervention. We performed an interrupted time-series analysis estimating rates of change before and after the intervention to account for the influence of secular trend. RESULTS: Of 1,574 patients delivering twins, 897 (57%) were included, with 479 in the 3 years before and 418 in the 3 years after the intervention. Adjusted rates of vaginal delivery increased from 32.1% (n=153) to 44.2% (n=185) before and after the intervention (P<.01), with a decrease in elective cesarean delivery from 54.6% (n=479) to 44.3% (n=185) (P<.01). Rates of breech extraction increased after the intervention (5.7% vs 9.3%, P=.04). However, there was no difference in the rate of change in twin vaginal birth in the time period before (1.35% annual increase, P=.76) or after (5.8% annual increase, P=.40) the intervention. CONCLUSIONS: Although we observed an increased rate of twin vaginal birth in the time period after our intervention, because the rates of increase before and after the intervention were not statistically different, the increase is not attributable to our intervention and is more properly attributed to secular trend.

The effect of uterine leiomyoma on the risk of malpresentation and cesarean: a meta-analysis.

BACKGROUND: some epidemiological studies have found that uterine leiomyoma can increase the risk of cesarean and malpresentation at term. To date, the meta-analysis has not been conducted for assessing the relationship between uterine leiomyoma and cesarean/malpresentation. This meta-analysis was conducted to estimate the association between uterine leiomyoma and the risk of cesarean/malpresentation. METHODS: A literature search was conducted out in major databases PubMed, Web of Science, and Scopus up to September 2016. The heterogeneity across studies was conducted by Q-test and I2 statistic. The publication bias was assessed by Begg's and Egger's tests. The results were shown using odds ratio (OR) estimate with 95% confidence intervals (CI) conducting a random-effect model. RESULTS: The literature search included 1244 articles until September 2016 with 232,177 participants. Based on OR estimates obtained from case-control and cohort studies, there was significant association between uterine leiomyoma and cesarean (2.60; 95% CI: 2.02, 3.18) and between leiomyoma and malpresentation at term (2.65; 95% CI: 1.60, 3.70). CONCLUSIONS: We showed based on reports in observational studies that uterine leiomyoma increased the risk of cesarean and malpresentation at term.

Neonatal outcomes of preterm twins according to mode of birth and presentation.

PURPOSE: To compare neonatal outcomes of twins delivered <33 weeks' gestation in tertiary centers in Canada according to the mode of birth and presentation. MATERIALS AND METHODS: This retrospective cohort from the Canadian Neonatal Network database studied preterm twins born from 24 + 0 to 32 + 6 weeks' gestation between 2005 and 2012. Twins were grouped by the mode of birth: both vaginal, combined vaginal/cesarean section (CS), and both CS. Additionally, twins were grouped by the mode of presentation: both vertex, vertex/breech, breech/vertex, and both breech. The primary outcome was a composite of mortality or severe neonatal morbidity (severe neurological injury [intraventricular hemorrhage grade 3/4 or periventricular leukomalacia], bronchopulmonary dysplasia, retinopathy of prematurity, and necrotizing enterocolitis). RESULTS: Of the 6636 twins, 1934 (29%) were delivered vaginally, 418 (6%) by combined vaginal birth/CS, and 4284 (65%) were born by CS. The composite did not differ between the groups. However, severe neurological injury was decreased (adjusted odds ratio [AOR], 0.77; 95% confidence interval [CI], 0.61-0.98) and respiratory distress syndrome (AOR, 1.34; 95%CI, 1.15-1.56) was increased when both the twins were delivered by CS. CONCLUSIONS: Preterm twin infants born via CS experienced less severe neurological injury when compared to those delivered vaginally, but had an increase in respiratory distress syndrome.
