A review of reproductive outcomes of women with two consecutive miscarriages and no living child.

J Obstet Gynaecol 2019 Apr 22:1-6. Epub 2019 Apr 22.

a Department of Obstetrics and Gynaecology , University College Cork , Cork , Ireland.

The definition of recurrent miscarriage ranges from two miscarriages according to the American Society for Reproductive Medicine and the European Society of Human Reproduction and Embryology, to three consecutive pregnancy losses as defined by the Royal College of Obstetricians and Gynaecologists. Recent guidelines emphasise the need for further research on the effect of various recurrent miscarriage definitions on diagnosis, treatment and prognosis. Our study examines the management and pregnancy outcomes of nulliparous women attending Cork University Maternity Hospital's Pregnancy Loss Clinic, between 2009 and 2014, with their second consecutive first-trimester miscarriage.

Comparing pregnancy outcomes and loss rates in elective twin pregnancy reduction to ongoing twin gestations in a large contemporary cohort.

Am J Obstet Gynecol 2019 Apr 14. Epub 2019 Apr 14.

Department of Obstetrics, Gynecology and Reproductive Science, Icahn School of Medicine at Mount Sinai, New York, New York.

Background: As compared to singleton gestations, twin pregnancies are associated with a significantly higher risk of preterm birth, maternal complications, as well as fetal and neonatal morbidity and mortality. Multifetal pregnancy reduction (MPR) is a technique developed in the 1980s to reduce the fetal number in higher-order multiple pregnancies to reduce the risk of adverse pregnancy outcomes, most importantly preterm birth.

Objective: To compare pregnancy outcomes and loss rates in elective twin pregnancy reduction to ongoing twin gestations in a large contemporary cohort. Read More

Economic Downturns and Inequities in Birth Outcomes: Evidence From 149 Million US Births.

Am J Epidemiol 2019 Feb 19. Epub 2019 Feb 19.

Heller School for Social Policy and Management, Brandeis University, Waltham, Massachusetts.

Using birth certificate data for nearly all registered US births from 1976 to 2016 and monthly data on state unemployment rates, we reexamined the link between macroeconomic variation and birth outcomes. We hypothesized that economic downturns reduce exposure to work-related stressors and pollution while increasing exposure to socioeconomic stressors like job loss. Because of preexisting inequalities in health and other resources, we expected that less-educated mothers and black mothers would be more exposed to macroeconomic variation. Read More

The hegemonic role of biomedical discourses in the construction of pregnancy loss.

Women Birth 2019 Mar 28. Epub 2019 Mar 28.

Department of Psychology. Stellenbosch University, South Africa.

Background And Problem: Pregnancy is constructed as a joy-filled and natural experience with a taken-for-granted expectation that the outcome will be a healthy baby. However, in South Africa approximately 1 in 4 pregnancies end in miscarriage and the stillbirth rate is 24 per 100 live births. Despite the overwhelming statistics, reproductive loss is considered a cultural taboo and continues to be silenced in various ways by the medical fraternity and society in general. Read More

Early first trimester transvaginal ultrasound is indicated in pregnancies after a previous cesarean delivery: should it be mandated?

Ultrasound Obstet Gynecol 2019 Jan 24. Epub 2019 Jan 24.

Department of Obstetrics, Gynecology, and Reproductive Science, Icahn School of Medicine at Mount Sinai, New York, New York.

In this opinion article, we provide compelling arguments of why early screening for pregnancies following previous cesarean delivery would be beneficial. First, we provide an overview of the perils of undiagnosed or misdiagnosed cesarean scar pregnancies (CSP), mostly with bleeding, but also with other complications, that may lead to multiple surgeries, uterine artery embolization, loss of fertility and in rare cases of documented deaths. There is well-documented histopathological connection between CSP and the placental adherence spectrum (PAS) suggesting that CSP is a precursor to PAS. Read More

Quantitative Ultrasound Biomarkers Based on Backscattered Acoustic Power: Potential for Quantifying Remodeling of the Human Cervix during Pregnancy.

Ultrasound Med Biol 2019 02 22;45(2):429-439. Epub 2018 Nov 22.

Medical Physics Department, University of Wisconsin, Madison, Wisconsin, USA. Electronic address:

As pregnancy progresses, the cervix remodels from a rigid structure to one pliable enough to allow delivery of a fetus, a process that involves progressive disorganization of cervical microstructure. Quantitative ultrasound biomarkers that may detect this process include those derived from the backscattered echo signal, namely, acoustic attenuation and backscattered power loss. We recently reported that attenuation and backscattered power loss are affected by tissue anisotropy and heterogeneity in the ex vivo cervix. Read More

Iron homeostasis in pregnancy and spontaneous abortion.

Am J Hematol 2019 Feb 26;94(2):184-188. Epub 2018 Nov 26.

Department of Medicine, David Geffen School of Medicine at University of California Los Angeles, Los Angeles, California.

During pregnancy, iron requirements are increased to support maternal erythropoietic expansion and fetal growth and development. To meet these requirements, dietary iron absorption increases, and available iron stores are mobilized. These adjustments are thought to be in large part mediated by the iron-regulatory hormone hepcidin, which controls the concentrations of ferroportin, the sole exporter of iron into the extracellular fluid and blood plasma.

"It's just one of those things people don't seem to talk about..." women's experiences of social support following miscarriage: a qualitative study.

BMC Womens Health 2018 10 29;18(1):176. Epub 2018 Oct 29.

Department of General Practice, University of Melbourne, Parkville, VIC, Australia.

Background: Miscarriage is a common event which is estimated to occur in approximately one in four confirmed pregnancies (Collins et al, Grief Matters Aust J Grief Bereave_ 17:44, 2014, St John et al, Aust J Adv Nurs_ 23:8, 2006). Social networks play an important role in supporting women following this event and positive support experiences can play a role in buffering women's experiences of grief, loss and psychological distress following miscarriage (Rowlands et al, J Reprod Infant Psychol_ 28:274-86, 2010, Stratton et al, Aust New Zeal J Obstet Gynaecol_ 48:5-11).

Methods: Women were recruited through existing networks known to the researcher, miscarriage support organisations and snowball sampling methods. Read More

Routine first-trimester screening for fetal trisomies in twin pregnancy: cell-free DNA test contingent on results from combined test.

Ultrasound Obstet Gynecol 2019 02 7;53(2):208-213. Epub 2018 Dec 7.

Harris Birthright Research Centre for Fetal Medicine, King's College Hospital, London, UK.

Objective: To report on the routine clinical implementation of cell-free DNA (cfDNA) analysis of maternal blood for trisomies 21, 18 and 13, contingent on the results of the first-trimester combined test in twin pregnancy.

Methods: Screening for trisomies 21, 18 and 13 was carried out in 959 twin pregnancies by assessment of a combination of maternal age, fetal nuchal translucency thickness, and serum free β-human chorionic gonadotropin and pregnancy-associated plasma protein-A at 11-13 weeks' gestation in two UK NHS hospitals. Women in the high-risk group (risk ≥ 1 in 100) were offered the option of invasive testing, cfDNA testing or no further testing, and those in the intermediate-risk group (risk 1 in 101 to 1 in 2500 in the first phase of the study and 1 in 101 to 1 in 500 in the second phase) were offered cfDNA or no further testing.

New insights into the mechanisms underlying recurrent pregnancy loss.

J Obstet Gynaecol Res 2019 Feb 16;45(2):258-265. Epub 2018 Oct 16.

Division of Biomedical Sciences, Clinical Science Research Laboratories, Warwick Medical School, University of Warwick, Coventry, UK.

Recurrent pregnancy loss (RPL), defined as multiple consecutive miscarriages, is a devastating disorder for which there are no good treatment options. Two opposing paradigms have emerged to explain RPL. The prevailing clinical viewpoint is that RPL is caused by a spectrum of subclinical disorders, ranging from thrombophilia to anatomical, endocrine and immunological disorders, that somehow converge on a 'fragile' early pregnancy state, leading to miscarriage.

Obesity and Weight Gain in Pregnancy and Postpartum: an Evidence Review of Lifestyle Interventions to Inform Maternal and Child Health Policies.

Front Endocrinol (Lausanne) 2018 26;9:546. Epub 2018 Sep 26.

London School of Hygiene and Tropical Medicine, University of London, London, United Kingdom.

Maternal obesity, excessive gestational weight gain (GWG) and post-partum weight retention (PPWR) constitute new public health challenges, due to the association with negative short- and long-term maternal and neonatal outcomes. The aim of this evidence review was to identify effective lifestyle interventions to manage weight and improve maternal and infant outcomes during pregnancy and postpartum. A review of systematic reviews and meta-analyses investigating the effects of lifestyle interventions on GWG or PPWR was conducted (Jan 2009-2018) via electronic searches in the databases Medline, Pubmed, Web of Science and Cochrane Library using all keywords related to obesity/weight gain/loss, pregnancy or postpartum and lifestyle interventions;15 relevant reviews were selected.

Risk of congenital toxoplasmosis in women with low or indeterminate anti-Toxoplasma IgG avidity index in the first trimester of pregnancy: an observational retrospective study.

Clin Microbiol Infect 2018 Oct 11. Epub 2018 Oct 11.

Sc Microbiologia e Virologia, Fondazione IRCCS Policlinico San Matteo, Pavia, Italy; Dipartimento di Medicina Interna e Terapia Medica, Universita Degli Studi di Pavia, Sc Microbiologia e Virologia, Fondazione IRCCS Policlinico San Matteo, Pavia, Italy.

Objectives: Congenital toxoplasmosis (CT) affects one to ten fetuses per 10 000 live newborns in western countries. Without knowing pre-conception serostatus, it is hard to date the infection when anti-Toxoplasma IgG and IgM antibodies are positive at first screening. Although a high IgG avidity index (AI) in the first trimester excludes CT, the same cannot be said of intermediate and low AI. Read More

Gestational hormone trajectories and early pregnancy failure: a reassessment.

Reprod Biol Endocrinol 2018 Oct 11;16(1):95. Epub 2018 Oct 11.

Department of Biostatistics and Epidemiology, Center for Clinical Epidemiology and Biostatistics, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA, 19104, USA.

Background: Studies have commonly assessed the endocrinolgical status of women once miscarriage is threatened or suspected; few studies have explored the antecedent hormonal environment or used a longitudinal strategy. Using refined statistical techniques, we sought to re-evaluate whether gestational hormone trajectories in early pregnancy can identify future miscarriage in asymptomatic pregnancies.

Methods: This prospective cohort study followed 105 women over-conception; 72 had normal term pregnancy outcomes while 33 experienced early pregnancy failure between 35 and 115 days of gestation. Read More

Is twin pregnancy, calving and pregnancy loss predictable by serum pregnancy-specific protein b (pspb) concentration 28-35 days after ai in dairy cows?

Acta Vet Hung 2018 Sep;66(3):451-461

3 National Agricultural Research and Innovation Center, Research Institute for Animal Breeding, Nutrition and Meat Science , Gesztenyés u. 1, H-2053 Herceghalom , Hungary.

Double ovulation occurs more frequently in multiparous cows with high milk production than in primiparous cows and the rate of twin pregnancy/calving is increasing worldwide. Diagnosis of twin pregnancy is possible by ultrasound at the time of early pregnancy examination [28-34 days after artificial insemination (AI)]. Pregnancy proteins are also well-known indicators of gestation. Read More
