BACKGROUND Placenta previa is defined as a placenta that grows from the anterior or posterior wall of the uterus and covers the cervix. The incidence of placenta previa has been increasing in recent years. It is thought that bleeding is more common during surgery in cases with anterior placenta that is closing the cervix. This study investigated the importance of placental location in pregnant women with placenta previa who had a previous cesarean section. MATERIAL AND METHODS This study covered the period from July 2017 to June 2020. The 116 patients included in the study were divided into 2 groups according to placental location: anterior (group 1) and posterior (group 2). All patients had previously delivered via cesarean section. Operation time, presence of invasion, estimated blood loss during surgery, and transfused erythrocyte volume were evaluated. Medical records were used to access the relevant data. RESULTS The patients in group 1 and group 2 had an average of 2.71 and 2.01 previous cesarean sections, respectively (P=0.002). The placental invasion (percreta) rate was significantly higher in group 1 than in group 2 (65.4 vs 5.3%, P<0.001), as was the estimated blood loss during surgery (790 vs 527 mL, P=0.014). The total erythrocyte suspension was considerably higher in group 1 than in group 2 patients (0.8 vs 0.2, P=0.014), both during and after surgery. CONCLUSIONS In patients with placenta previa, the location of the placenta should always be examined with ultrasonography to allow better preoperative planning.

Article Synopsis
- The study aims to analyze the risk of maternal morbidity based on how pregnancies were achieved, focusing on various methods of medically assisted reproduction like fertility drugs, IUI, and ART.
- Data from Utah's birth certificates (2009-2017) showed that 4.8% of pregnancies were from assisted reproduction, with maternal morbidity defined by complications like blood transfusions and ICU admissions.
- Results indicated higher maternal morbidity risks for those using assisted reproduction, particularly with ART and autologous oocytes, although these risks decreased when controlling for factors like multiple pregnancies and existing health issues.

Purpose: The purpose of this study is to compare obese and non-obese women with multiple pregnancies to determine the effects on pregnancy, delivery, and neonatal outcomes.
Methods: We conducted a retrospective population-based study utilizing data collected between 2004 and 2014 inclusively, from the Healthcare Cost and Utilization Project-Nationwide Inpatient Sample. A total of 137,303 multiple pregnancies were analyzed; 130,542 (95%) were non-obese, while 6761 (5%) were obese.

Article Synopsis
- Placenta previa is a condition where the placenta implants abnormally in the lower uterus, leading to serious risks for both the mother and fetus, including hemorrhage and stillbirth.
- This study focused on analyzing microRNA expression in the blood during the first trimester of pregnancies that later developed placenta previa, comparing them to normal pregnancies.
- The results showed that several microRNAs were downregulated in those pregnancies, with a combination of seven specific microRNAs accurately distinguishing between healthy and placenta previa pregnancies early on.

Article Synopsis
- Marginal cord insertion (MCI) is considered a pathological condition that requires early diagnosis and understanding its risk factors can improve prenatal care.
- A meta-analysis of 18 studies revealed that the prevalence of MCI in singleton pregnancies is 5.71%, identifying significant risk factors such as assisted reproductive technology, chronic hypertension, placenta previa, and nulliparity.
- The analysis followed strict guidelines and methods to ensure quality, indicating that factors like smoking, maternal age, and prior Cesarean sections were not significantly associated with MCI.
