Postoperative atrial fibrillation after cesarean delivery.

Rom J Anaesth Intensive Care 2018 Oct;25(2):111-116

Tampa General Hospital, University of South Florida Morsani College of Medicine, USA.

Background And Aims: Atrial fibrillation (AF) is the most common arrhythmia seen clinically. Due to the lack of literature and guidelines on maternal AF as a postoperative complication following cesarean delivery (CD), we undertook a study to characterize parturients who developed AF following CD and to evaluate arrhythmia management and outcomes in this patient population.

Methods: After receiving ethics committee approval, a retrospective chart review was performed to determine the incidence, possible risk factors, treatment, and outcome of women who developed AF following CD performed between 2003 and 2012 at New York Methodist Hospital in Brooklyn, New York.

Timing induction of labour at 41 or 42 weeks? A closer look at time frames of comparison: A review.

Midwifery 2018 Nov 11;66:111-118. Epub 2018 Aug 11.

Department of Obstetrics and Gynaecology, Amsterdam UMC, University of Amsterdam, Meibergdreef 9, Amsterdam, The Netherlands.

Background: Postterm pregnancy is associated with increased perinatal risk. The WHO defines postterm pregnancy as a pregnancy at or beyond 42 weeks + 0 days, though currently labour is induced at 41 weeks in many settings. Guidelines on timing of labour induction are frequently based on the Cochrane systematic review 'Induction of labour for improving birth outcomes for women at or beyond term' in which is concluded that a policy of induction of labour is associated with fewer adverse perinatal outcome and fewer Caesarean sections.

Am J Obstet Gynecol 2017 10 12;217(4):443.e1-443.e11. Epub 2017 Jun 12.

Mouse Imaging Centre, The Hospital for Sick Children, Toronto, Ontario, Canada; Department of Physiology and Experimental Medicine, The Hospital for Sick Children, Toronto, Ontario, Canada; Department of Medical Biophysics, University of Toronto, Toronto, Ontario, Canada; Department of Obstetrics and Gynecology, University of Toronto, Toronto, Ontario, Canada. Electronic address:

Background: Many stillbirths of normally formed fetuses in the third trimester could be prevented via delivery if reliable means to anticipate this outcome existed. However, because the etiology of these stillbirths is often unexplained and although the underlying mechanism is presumed to be hypoxia from placental insufficiency, the placentas often appear normal on histopathological examination. Gestational age is a risk factor for antepartum stillbirth, with a rapid rise in stillbirth rates after 40 weeks' gestation. Read More

Study protocol of SWEPIS a Swedish multicentre register based randomised controlled trial to compare induction of labour at 41 completed gestational weeks versus expectant management and induction at 42 completed gestational weeks.

BMC Pregnancy Childbirth 2016 Mar 7;16:49. Epub 2016 Mar 7.

Gothenburg University, Perinatal centre, Department of Obstetrics and Gynecology, Institute of Clinical Sciences, Sahlgrenska Academy, Sahlgrenska University Hospital, East, S-416 85, Gothenburg, Sweden.

Background: Observational data shows that postterm pregnancy (≥42 gestational weeks, GW) and late term pregnancy (≥41 GW), as compared to term pregnancy, is associated with an increased risk for adverse outcome for the mother and infant. Standard care in many countries is induction of labour at 42 GW. There is insufficient scientific support that induction of labour at 41 GW, as compared with expectant management and induction at 42 GW will reduce perinatal mortality and morbidity without an increase in operative deliveries, negative delivery experiences or higher costs.

Methods: amniotic fluid volume was measured, using Single Deepest Vertical Pocket (SDVP) and Amniotic Fluid Index (AFI), in 961 singleton uncomplicated prolonged pregnancies. In 109 of these patients, hospitalization was planned for induction of labor, during or after 42 weeks of gestation, for oligohydramnios, postterm pregnancy and other indications in 47, 51 and 11 cases, respectively.

Preeclampsia, biomarkers, syncytiotrophoblast stress, and placental capacity.

Am J Obstet Gynecol 2015 Oct;213(4 Suppl):S9.e1, S9-11

Faculty of Medicine, University of Oslo, and Department of Obstetrics and Department of Gynecology, Oslo University Hospital, Oslo, Norway.

The maternal syndrome of preeclampsia is mediated by dysfunctional syncytiotrophoblast (STB). When this is stressed by uteroplacental malperfusion, its signaling to the mother changes, as part of a highly coordinated stress response. The STB signals are both proinflammatory and dysangiogenic such that the preeclamptic mother has a stronger vascular inflammatory response than normal, with an antiangiogenic bias. Read More

Physical fitness, serum relaxin and duration of gestation.

BMC Pregnancy Childbirth 2015 Aug 14;15:168. Epub 2015 Aug 14.

Department of Public Health and Caring Sciences, Uppsala University, Uppsala, SE-75122, Sweden.

Background: Women are recommended to perform regular exercise during pregnancy but the impact of physical fitness on duration of gestation and miscarriage is inconsistent. In addition, a dose-response relation between the amount of weekly exercise and increased risk of miscarriage in early pregnancy has been observed. Previous studies have mostly used an epidemiologic method. Read More

Risk of spontaneous abortion and other pregnancy outcomes in 15-25 year old women exposed to human papillomavirus-16/18 AS04-adjuvanted vaccine in the United Kingdom.

Vaccine 2015 Nov 21;33(48):6884-91. Epub 2015 Jul 21.

University of California San Diego School of Medicine, USA.

Background: We assessed the risk of spontaneous abortion (SA) after inadvertent exposure to HPV-16/18-vaccine during pregnancy using an observational cohort design.

Methods: The study population included women aged 15-25 years registered with the Clinical Practice Research Datalink General Practice OnLine Database in the United Kingdom (UK), who received at least one HPV-16/18-vaccine dose between 1st September 2008 and 30th June 2011. Exposed women had the first day of gestation between 30 days before and 45 days (90 days for the extended exposure period) after any HPV-16/18-vaccine dose. Read More

Toll-Like Receptor 4 Is an Essential Upstream Regulator of On-Time Parturition and Perinatal Viability in Mice.

Endocrinology 2015 Oct 7;156(10):3828-41. Epub 2015 Jul 7.

Robinson Research Institute and School of Medicine (H.H.W., C.D., P.Y.C., M.R.H., L.M.M., S.A.R.), University of Adelaide, Adelaide SA 5005, Australia; Chemical Biology Research Branch (K.C.R.), National Institute on Drug Abuse and National Institute on Alcohol Abuse and Alcoholism, National Institutes of Health, Rockville, Maryland 20892; and Departments of Obstetrics and Gynecology, Pediatrics and Physiology (D.M.O.), University of Alberta, Edmonton, Canada AB TG62S2.

An inflammatory response is instrumental in the physiological process of parturition but the upstream signals initiating inflammation are undefined. Because endogenous ligands for Toll-like receptor 4 (TLR4) are released in late gestation, we hypothesized that on-time labor requires TLR4 signaling, to trigger a cytokine and leukocyte response and accelerate the parturition cascade. In pregnant TLR4-deficient (Tlr4-/-) mice, average gestation length was extended by 13 hours and increased perinatal mortality was seen compared with wild-type controls. Read More

Diagnosis, antenatal surveillance and management of prolonged pregnancy: current perspectives.

Minerva Ginecol 2015 Aug;67(4):365-73

Department of Medical Surgical Specialties, Gynecology and Obstetrics Section, University of Catania, Catania, Italy -

Prolonged pregnancy is defined as a pregnancy that extends beyond 42 weeks of gestation (294 days) from the first day of the last normal menstrual period. An accurate estimation of the 'natural' incidence of prolonged pregnancy would require meticulous early pregnancy dating. The use of ultrasound to establish gestational age reduces the number of pregnancies that are classified as prolonged. Read More
