Epidemiology, Risk Factors, and Perinatal Outcomes of Placental Abruption-Detailed Annual Data and Clinical Perspectives from Polish Tertiary Center.

Int J Environ Res Public Health 2022 Apr 23;19(9). Epub 2022 Apr 23.

Center of Postgraduate Medical Education, Second Department of Obstetrics and Gynecology, 01-813 Warsaw, Poland.

Benckiser's hemorrhage: about an uncommon case report.

Int J Surg Case Rep 2022 Apr 27;95:107128. Epub 2022 Apr 27.

Gynaecology-Obstetrics and Endoscopy Department, Maternity Souissi, University Hospital Center IBN SINA, University Mohammed V, Rabat, Morocco.

Background: Benckiser's hemorrhage is a serious obstetric emergency caused by rupture of one or more umbilical vessels of velamentous insertion, putting the fetus in distress and leading to rapid fetal death through exsanguination in utero. It is an uncommon condition associated with a neonatal mortality rate of 75-100%. This hemorrhage of fetal origin happens most often when the membranes rupture, whether spontaneously or artificially.

Hum Reprod 2022 May 13. Epub 2022 May 13.

Department of Biomedical Sciences, Humanitas University, Pieve Emanuele-Milan, Italy.

Study Question: Is there an association between the different endometrial preparation protocols for frozen embryo transfer (FET) and obstetric and perinatal outcomes?

Summary Answer: Programmed FET protocols were associated with a significantly higher risk of hypertensive disorders of pregnancy (HDP), pre-eclampsia (PE), post-partum hemorrhage (PPH) and cesarean section (CS) when compared with natural FET protocols.

What Is Known Already: An important and growing source of concern regarding the use of FET on a wide spectrum of women, is represented by its association with obstetric and perinatal complications. However, reasons behind these increased risks are still unknown and understudied. Read More

Is the lack of prior exposure to sperm antigens associated with worse neonatal and maternal outcomes? A 10-year single-center experience comparing ICSI-TESE pregnancies to ICSI pregnancies.

Andrology 2022 Apr 29. Epub 2022 Apr 29.

Division of Gynecology and Reproductive Medicine, Department of Gynecology, Fertility Center, Humanitas Clinical and Research Center IRCCS, Rozzano, Milan, Italy.

Background: Nowadays, pathogenesis of preeclampsia (PE) is still unknown. Among the different etiological hypotheses, some authors proposed that it might be because of an abnormal immunologic response to a foreign fetal antigen derived from the father's spermatozoa. Indeed, the fetus is considered a semi-allograft, being one half paternally derived in its antigenicity, and the first pathogenic insult of PE may be an abnormal maternal immune response toward this semi-allogenic implant.

J Basic Clin Physiol Pharmacol 2022 Apr 8. Epub 2022 Apr 8.

Department of Public Health, School of Medicine, University of Naples Federico II, Naples, Italy.

Objectives: To evaluate anxiety and psychological impact of abnormally invasive placenta (AIP) diagnosis during pregnancy.

Methods: A cross-sectional survey study was performed to assess the psychological response of pregnant women with an antenatally AIP diagnosis. The psychological impact was measured through a visual analogue scale (VAS) for anxiety, which ranged from 0 (not at all anxious) to 100 (extremely anxious) and was referred to three questions: (1) How anxious were you the first time they counselled you about AIP?; (2) How anxious were you the day of the planned cesarean delivery in terms of morbidity/mortality?; (3) How anxious were you in terms of future sexual activities?

Results: 48 singleton pregnancies that underwent planned cesarean hysterectomy for AIP, met the inclusion criteria and were surveyed for the study. Read More

Comparison of Perinatal Outcomes of Letrozole-Induced Ovulation and Hormone Replacement Therapy Protocols in Patients With Abnormal Ovulation Undergoing Frozen-Thawed Embryo Transfer: A Propensity Score Matching Analysis.

Front Endocrinol (Lausanne) 2022 16;13:837731. Epub 2022 Mar 16.

Reproduction Center, The Third Affiliated Hospital of ZhengZhou University, ZhengZhou, China.

Background: With the increasing use of frozen embryo transfer (FET), the best endometrial preparation protocol is continuously being discussed.
