Objective: To evaluate the risk of spontaneous preterm birth with or without universal transvaginal ultrasound cervical length screening at the time of midtrimester scan.

Data Sources: Medline, Embase, ClinicalTrials.gov, and Web of Science were systematically searched from the inception of the databases to November 12, 2023, using combinations of the relevant medical subject heading terms, key words, and word variants that were considered suitable for the topic.

Objective: Cesarean hysterectomy is generally presumed to decrease maternal morbidity and mortality secondary to placenta accreta spectrum disorder. Recently, uterine-sparing techniques have been introduced in conservative management of placenta accreta spectrum disorder to preserve fertility and potentially reduce surgical complications. However, despite patients often expressing the intention for future conception, few data are available regarding the subsequent pregnancy outcomes after conservative management of placenta accreta spectrum disorder.

Objective: This study aimed to examine the association between cervical length and the risk of adverse outcomes in placenta previa pregnancies. In addition, the diagnostic accuracy of cervical length in predicting emergency cesarean delivery due to hemorrhage was evaluated.

Data Sources: PubMed, Web of Science, and Embase were systematically searched up to January 21, 2023.

Article Synopsis
  • * Conducted as a randomized trial with 70 patients, results showed that both single and repeated MSC infusions improved LVEF, but the repeated infusion yielded a significantly greater improvement at 6 months.
  • * The findings suggest that administering a booster dose of WJ-MSCs after an initial treatment can enhance cardiac recovery in patients who suffered an AMI.

To evaluate obstetrical outcomes for women having late amniocentesis (on or after 24 weeks). Electronic databases were searched from inception to January 1st, 2023. The obstetrical outcomes evaluated were gestational age at delivery, preterm birth (PTB) < 37 weeks, PTB within 1 week from amniocentesis, premature prelabor rupture of membranes (pPROM), chorionamnionitis, placental abruption, intrauterine fetal demise (IUFD) and termination of pregnancy (TOP).

Twin reversed arterial perfusion (TRAP) sequence or acardiac twin is a rare and severe complication of monochorionic multiple pregnancies. Acardiac twin accounts for 10% of all TRAP sequences, which is the most morphologically developed acardius. We present an undiagnosed TRAP sequence case up to 24 weeks of gestation who underwent successful amnioreduction, radiofrequency ablation (RFA), and intrauterine transfusion (IUT).

Objective: This study aimed to assess the effectiveness of prophylactic ureteral stent placement for the prevention of genitourinary tract injury at the time of cesarean hysterectomy for placenta accreta spectrum. The secondary objectives were to assess mean blood loss, operative time, number of packed red blood cells transfused, and rates of urinary tract infection among patients undergoing cesarean hysterectomy for placenta accreta spectrum with and without prophylactic ureteral stent placement.

Data Sources: The search was performed using PubMed, Cochrane Library, and ClinicalTrials.

Article Synopsis
  • The study looked at two ways to treat a condition called stage I twin-to-twin transfusion syndrome in pregnant women: one way involved a special laser treatment, and the other was just waiting and monitoring.
  • Researchers checked several medical databases to gather information and compared the results from five different studies.
  • They found that there wasn’t a big difference in the survival of the babies between the two treatments and that using the laser treatment might not be necessary if the mother didn't have any serious problems.

Background: Pulmonary stenosis (PS) is a congenital heart diseases (CHDs) with a spectrum of stenosis. Monochorionic (MC) twins are at increased risk of CHDs, especially acquired CHDs in twin-twin transfusion syndrome (TTTS). PS/Pulmonary atresia (PA) is a rare coincidence with TTTS.

Objective: We aimed to evaluate whether there is a significant association between a placental pathology diagnosis basal plate myofibers (BPMF) in an index pregnancy with placenta accreta spectrum (PAS) in the subsequent pregnancy.

Study Design: We conducted a retrospective nested cohort study of all cases with a histopathological finding of BPMF between August 2012 and March 2020 at a single tertiary referral center. Data were collected for all subjects (cases and controls) with at least two consecutive pregnancies (the initial index pregnancy and at least one subsequent pregnancy) accompanied by a concomitant record of histopathological study of the placenta at our center.

In recent years, transcriptomics has enabled us to gain a deeper understanding of fundamental reproductive physiology, including the menstrual cycle, through a more precise molecular analysis. The endometrial mRNA transcript levels fluctuate during the normal menstrual cycle, indicating changes in the relative recruitment and abundance of inflammatory cells, as well as changes in the receptivity and remodeling of the endometrium. In addition to providing a more comprehensive understanding of the molecular underpinnings of pathological gynecological conditions such as endometriosis, leiomyomas, and adenomyosis through RNA sequencing, this has allowed researchers to create transcriptome profiles during both normal menstrual cycles and pathological gynecological conditions.

Article Synopsis
  • In utero repair of open neural tube defects can be performed through two main approaches: open hysterotomy, which has shown better motor outcomes, and laparotomy-assisted fetoscopic repair, which may have fewer complications.
  • This study evaluated the maternal and fetal complications of both surgical methods over a period from 2011 to 2021, using a classification system to rate the severity of complications.
  • Results indicated that the hybrid approach generally had a higher gestational age at surgery, a lower maternal BMI, and longer surgical duration, but it also resulted in fewer severe complications compared to the open approach.

Objective: This meta-analysis was conducted to (1) assess the quantity and dose of perioperatively dispensed opioids for benign hysterectomy by procedure route and (2) identify the predictors of persistent opioid use after the procedure.

Data Sources: PubMed, Web of Science, and Embase were systematically searched from study inception to 25 March 2022.

Study Eligibility Criteria: Studies reporting data on opioid dispensing among patients undergoing benign hysterectomy were considered eligible.

Objective: To investigate the impact of endometrial receptivity array (ERA) before frozen embryo transfer in patients undergoing in vitro fertilization (IVF). There is a lack of consensus regarding the use of ERA for increasing the success rate of IVF cycles, mainly in terms of the live birth rate.

Design: PubMed, Web of Science and Embase were searched from inception up to February 15, 2022.

Article Synopsis
  • * It included 9 studies with over 11,500 pregnant individuals, revealing that those who were incarcerated had a significantly higher risk of inadequate prenatal care and a greater likelihood of giving birth to low birthweight babies compared to non-incarcerated counterparts.
  • * The research highlighted the need for more studies to explore the impacts of inadequate prenatal care on pregnancy outcomes and to improve care for incarcerated pregnant individuals.

Introduction: Caesarean section (C/S) rates have significantly increased across the world over the past decades. In the present population-based study, we sought to evaluate the association between C/S and neonatal mortality rates.

Material And Methods: This retrospective ecological study included longitudinal data of 166 countries from 2000 to 2015.

Importance: Primary studies proposed that aberrant maternal antiviral immunity and/or giving birth in quarantine, such as during the ongoing COVID-19 pandemic, may be associated with the risk of neurodevelopmental impairment (NDI) in offspring.

Objectives: To evaluate the associations of birth and being raised during the COVID-19 pandemic with risk of NDI among infants and to assess the association of gestational exposure to SARS-CoV-2 with risk of NDI.

Data Sources: PubMed, Web of Science, Scopus, Embase, and preprint servers were systematically searched from inception to March 25, 2022.

Background: Single fetal demise after intervention for twin-twin transfusion syndrome is a relatively common complication and is often devastating for the patients.
