A case of total hysterectomy due to massive maternal bleeding immediately after fetoscopic laser surgery for twin-twin transfusion syndrome.

J Obstet Gynaecol Res 2021 Apr 11. Epub 2021 Apr 11.

Department of Obstetrics and Gynecology, Yamaguchi University Graduate School of Medicine, Ube, Japan.

Twin-twin transfusion syndrome (TTTS) complicates approximately 10% of monochorionic twin pregnancies and is associated with almost 90% mortality if left untreated. Fetoscopic laser photocoagulation (FLP) is the first-line therapy for TTTS, and an overall twin survival rate of 75% and at least one survival rate of 90% have been established. We report a case of TTTS complicated with bleeding from the uterine wall by inserting the procedure after FLP. Read More

Vitamin D status in women with dichorionic twin pregnancies and their neonates: a pilot study in China.

BMC Pregnancy Childbirth 2021 Apr 8;21(1):279. Epub 2021 Apr 8.

International Collaborative Laboratory of Reproduction and Development of Chinese Ministry of Education, Chongqing Medical University, Chongqing, 400016, China.

Background: Vitamin D deficiency is a global public health issue in women and children and is associated with adverse impacts on child growth, such as rickets. However, prior studies have mainly focused on measuring vitamin D levels in singleton pregnant women and their offspring, and very limited studies have revealed the prevalence of vitamin D deficiency in twin pregnant women and their offspring. The aim of this study was to investigate vitamin D levels in twin-pregnant women and their neonates. Read More

The Detection, Outcome, and Presentation of Twin-Twin Transfusion Syndrome in Monochorionic Diamniotic Twin Pregnancies Followed with a Protocol of Fortnightly Ultrasound Examination.

Fetal Diagn Ther 2021 Apr 6:1-8. Epub 2021 Apr 6.

Department of Obstetrics and Gynecology, University Hospitals Leuven, Leuven, Belgium.

Background: Evidence to support a fortnightly scan protocol for monochorionic diamniotic (MCDA) pregnancies to detect twin-twin transfusion syndrome (TTTS) is scarce. Also, TTTS-related mortality in an unselected cohort is not well documented. Finally, common knowledge suggests that a more frequent follow-up may pick up the disease at a milder stage, but little is known on the ultrasound findings before the diagnosis. Read More

A comparative study of two immunoassays of maternal placental growth factor.

Scand J Clin Lab Invest 2021 Apr 6:1-6. Epub 2021 Apr 6.

National Perinatal Epidemiology Centre, University College Cork, Cork, Ireland.

Circulating maternal levels of placental growth factor correlates well with placental function and numerous studies advocate its role to help rule-out preterm pre-eclampsia. A number of automated immunoassay platforms to quantify placental growth factors are currently available. The aim of this study was to highlight the importance of developing and validating appropriate reference ranges and clinical cut-offs for immunoassays, by comparing the results obtained from two different immunoassays of placental growth factor; the Quantikine ELISA and the automated Triage test.

Individualized embryo selection strategy developed by stacking machine learning model for better in vitro fertilization outcomes: an application study.

Reprod Biol Endocrinol 2021 Apr 5;19(1):53. Epub 2021 Apr 5.

Reproductive Medicine Center, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, No.1095, Jiefang Road, Wuhan, 430030, China.

Background: To minimize the rate of in vitro fertilization (IVF)- associated multiple-embryo gestation, significant efforts have been made. Previous studies related to machine learning in IVF mainly focused on selecting the top-quality embryos to improve outcomes, however, in patients with sub-optimal prognosis or with medium- or inferior-quality embryos, the selection between SET and DET could be perplexing.

Methods: This was an application study including 9211 patients with 10,076 embryos treated during 2016 to 2018, in Tongji Hospital, Wuhan, China. Read More

Genomic Prediction for Twin Pregnancies.

Animals (Basel) 2021 Mar 16;11(3). Epub 2021 Mar 16.

Zoetis Genetics, 333 Portage Street, Kalamazoo, MI 49007, USA.

Twinning is a multifactorial trait influenced by both genetic and environmental factors that can negatively impact animal welfare and economic sustainability on commercial dairy operations. To date, using genetic selection as a tool for reducing twinning rates on commercial dairies has been proposed, but not yet implemented. In response to this market need, Zoetis (Kalamazoo, MI, USA) has developed a genomic prediction for twin pregnancies, and included it in a comprehensive multitrait selection index. Read More

Twin-to-Twin Transfusion Syndrome: Diagnostic Imaging and Its Role in Staving Off Malpractice Charges and Litigation.

Diagnostics (Basel) 2021 Mar 4;11(3). Epub 2021 Mar 4.

Department of Anatomical, Histological, Forensic, and Orthopedic Sciences, Sapienza University of Rome, 00161 Rome, Italy.

The study aims to expound upon the imaging-based diagnostic methodologies aimed at identifying twin-to-twin transfusion syndrome (TTTS), a serious, somewhat rare prenatal condition that takes place in pregnancies where identical twins, or other multiples, share a placenta (monochorionic placenta), highlighting how medico-legal outcomes can be affected by provable compliance with consolidated diagnostic guidelines or best practices. It is of utmost importance to produce a prompt identification of TTTS instances; an early diagnosis is in fact critical in order to effectively treat and manage TTTS. By virtue of TTTS being a highly progressive condition, a delay in diagnosis can result in disastrous outcomes; just a few weeks delay in the diagnosis of TTTS can turn out fatal for one or both twins.

Department of Obstetrics and Gynecology, Filantropia Clinical Hospital, 011171 Bucharest, Romania.

Monochorionic monoamniotic pregnancy are considered high risk gestations and the fetal outcome is at times unpredictable. Correct diagnosis and counselling are extremely important, especially regarding the risk of unexpected fetal demise. We present the rare case of a monochorionic monoamniotic twin pregnancy with early identification of cord entanglement and the characteristic ultrasound findings in the first trimester of pregnancy.

SARS-CoV-2 Infection and Inflammatory Response in a Twin Pregnancy.

Int J Environ Res Public Health 2021 03 17;18(6). Epub 2021 Mar 17.

Institute for Maternal and Child Health "IRCCS Burlo Garofolo", via Dell'istria 65/1, 34124 Trieste, Italy.

There is growing literature about the SARS-CoV-2 pathogenetic effects exerted during pregnancy and whether vertical transmission or premature birth is possible. It is not well known whether changes in the immune system of pregnant women may lead to a marked susceptibility to infectious processes and the risk of adverse maternal and neonatal complications such as preterm birth, spontaneous abortion, hospitalization in an intensive care unit, transmission to the fetus or newborns, and fetal mortality are poorly understood. Along with this ongoing debate, it is not well defined whether, during pregnancy, the role of host susceptibility in producing a specific inflammatory response to SARS-CoV-2 may represent distinctive markers of risk of vertical transmission.
