title: Placenta accreta spectrum into the parametrium, morbidity differences between upper and lower location

description: To demonstrate the surgical and morbidity differences between upper and lower parametrial placenta invasion (PPI). Forty patients with placenta accreta spectrum (PAS) into the parametrium underwent surgery between 2015 and 2020. Based on the peritoneal reflection, the study compared two types of parametrial placental invasion (PPI), upper or lower. Surgical approach to PAS follows a conservative-resective method. Before delivery, surgical staging by pelvic fascia dissection established a final diagnosis of placental invasion. In upper PPI cases, the team attempted to repair the uterus after resecting all invaded tissues or performing a hysterectomy. In cases of lower PPI, experts performed a hysterectomy in all cases. The team only used proximal vascular (aortic occlusion) control in cases of lower PPI. Surgical dissection for lower PPI started finding the ureter in the pararectal space, ligating all the tissues (placenta and newly formed vessels) to create a tunnel to release the ureter from the placenta and placenta suppletory vessels. Overall, at least three pieces of the invaded area were sent for histological analysis. Forty patients with PPI were included, 13 in the upper parametrium and 27 in the lower parametrium. MRI indicated PPI in 33/40 patients; in three, the diagnosis was presumed by ultrasound or medical background. The intrasurgical staging categorizes 13 cases of PPI performed and finds diagnosis in seven undetected cases. The expertise team completed a total hysterectomy in 2/13 upper PPI cases and all lower PPI cases (27/27). Hysterectomies in the upper PPI group were performed by extensive damage of the lateral uterine wall or with a tube compromise. Ureteral injury ensued in six cases, corresponding to cases without catheterization or incomplete ureteral identification. All aortic vascular proximal control (aortic balloon, internal aortic compression, or aortic loop) was efficient for controlling bleeding; in contrast, ligature of the internal iliac artery resulted in a useless procedure, resulting in uncontrollable bleeding and maternal death (2/27). All patients had antecedents of placental removal, abortion, curettage after a cesarean section, or repeated D&C. Lower PAS parametrial involvement is uncommon but associated with elevated maternal morbidity. Upper and lower PPI has different surgical risks and technical approaches; consequently, an accurate diagnosis is needed. The clinical background of manual placental removal, abortion, and curettage after a cesarean or repeated D&C could be ideally studied to diagnose a possible PPI. For patients with high-risk antecedents or unsure ultrasound, a T2 weight MRI is always recommended. Performing comprehensive surgical staging in PAS allows the efficient diagnosis of PPI before using some procedures.

title: Treatments for cesarean scar pregnancy: 11-year experience at a medical center

description: Cesarean scar pregnancy (CSP) is a long-term complication after cesarean section that can cause severe maternal morbidity and mortality. Although a variety of treatments have been described, there is no consensus as to the optimal management approach. Many grading systems for CSP have been proposed, among which the classification made by the consensus of Chinese experts in 2016 was shown to provide improved treatment guidance for clinical practice. The purpose of the present study was to analyze the success rate of different treatments for each type of CSP as classified according to the Chinese Expert’s Consensus (2016), and to develop a management strategy for CSP. A retrospective study was performed among patients diagnosed with CSP at Shandong Provincial Hospital between January 2009 and December 2019. We reviewed clinical characteristics, treatment methods, and subsequent outcomes; and analyzed these endpoints using the statistical software package SPSS 22.0 (SPSS, Inc., Chicago, IL). For type I CSP, systemic methotrexate (MTX) administration exhibited a success rate of 79.2% for type Ia and 14.3% for type Ib. Local and systemic MTX administration success rates were 88.9% for type Ia and 66.7% for type Ib. Dilation and curettage (D&C), curettage after uterine artery embolization (UAE + C), and hysteroscopic curettage (H + C) were 100% successful. For type II, UAE + C, H + C, and laparoscopy combined with hysteroscopic curettage (L + H+C) were 100% successful. D&C had a success rate of 97.0% for type IIa and 88.9% for type IIb. The success rate of systemic MTX administration was 52.0% for type IIa and 62.5% for type IIb. Both UAE + C and L + H+C had 100% success rates for type IIIa CSPs, while for type IIIb, the success rate was 87.9% for UAE + C vs. 96.6% for L + H+C. For type I CSPs, D&C was quick, easy, and safe; for type II, H + C was more suitable. For type III and some type II patients who wished to undergo simultaneous repair of the cesarean defect, L + H+C was the optimal method. UAE can be used as a complementary option instead of a prophylactic measure, and when difficulties with endoscopic surgeries were encountered, conversion to laparotomy was the ultimate treatment.

title: Fetal and maternal Doppler adaptation to maternal exercise during pregnancy: a randomized controlled trial

description: Regular and supervised exercise during pregnancy is worldwide recommended due to its proven benefits, but, during exercise, maternal blood flow is redirected from the viscera to the muscles and how fetal wellbeing may be affected by this redistribution is still not well known. To analyze the longitudinal effect of a supervised moderate physical exercise program during pregnancy on uteroplacental and fetal Doppler parameters. This is a planned secondary analysis of an randomized controlled trial (RCT), performed at Hospital Universitario de Torrejón, Madrid, Spain, including 124 women randomized from 12<sup>+0</sup> to 15<sup>+6</sup> weeks of gestation to exercise vs. control group. Fetal umbilical artery (UA), middle cerebral artery, and uterine artery pulsatility index (PI), were longitudinally collected by Doppler ultrasound assessment throughout gestation, and derived cerebroplacental ratio (normalized by <i>z</i>-score), and maternal mean PI in the uterine arteries (normalized by multiplies of the median). Obstetric appointments were scheduled at 12 (baseline, 12<sup>+0</sup> to 13<sup>+5</sup>), 20 (19<sup>+0</sup> to 24<sup>+2</sup>), 28 (26<sup>+3</sup> to 31<sup>+3</sup>) and 35 weeks (32<sup>+6</sup> to 38<sup>+6</sup>) of gestation. Generalized estimating equations were adjusted to assess longitudinal changes in the Doppler measurements according to the randomization group. No significant differences in the fetal or maternal Doppler measurements were found at any of the different checkup time points studied. The only variable that consistently affected the Doppler standardized values was gestational age at the time of assessment. The evolution of the UA PI <i>z</i>-score during the pregnancy was different in the two study groups, with a higher <i>z</i>-score in the exercise group at 20 weeks and a subsequent decrease until delivery while in the control group it remained stable at around zero. A regular supervised moderate exercise program during pregnancy does not deteriorate fetal or maternal ultrasound Doppler parameters along the pregnancy, suggesting that the fetal well-being is not compromised by the exercise intervention. Fetal UA PI <i>z</i>-score decreases during pregnancy to lower levels in the exercise group compared with the control group.

title: Association of maternal methionine synthase reductase gene polymorphisms with the risk of congenital heart disease in offspring: a hospital-based case-control study

description: Evidence suggests that periconceptional folic acid supplementation may prevent congenital heart disease (CHD). Methionine synthase reductase (<i>MTRR</i>) is one of the key regulatory enzymes in the folate metabolic pathway. This study aimed to comprehensively evaluate the association of single nucleotide polymorphisms (SNPs) in the maternal <i>MTRR</i> gene with CHD risk in offspring. A hospital-based case-control study involving 740 mothers of CHD cases and 683 health controls was conducted. The study showed that maternal <i>MTRR</i> gene polymorphisms at rs1532268 (C/T <i>vs.</i> C/C: aOR = 1.524; T/T <i>vs.</i> C/C: aOR = 3.178), rs1802059 (G/A <i>vs.</i> G/G: aOR = 1.410; A/A <i>vs.</i> G/G: aOR = 3.953), rs2287779 (G/A <i>vs.</i> G/G: aOR = 0.540), rs16879334 (C/G <i>vs.</i> C/C: aOR = 0.454), and rs2303080 (T/A <i>vs.</i> T/T: aOR = 0.546) were associated with the risk of CHD. And seven haplotypes were observed to be associated with the risk of CHD, T-G-A haplotype (OR = 1.298), C-A-C-C (OR = 4.824) and A-G haplotype (OR = 1.751) were associated with increased risk of CHD in offspring; A-A-A (OR = 0.773), T-A-A (OR = 0.557), G-A-C-C (OR = 0.598) and G-C (OR = 0.740) were associated with decreased risk of CHD in offspring. Maternal <i>MTRR</i> gene polymorphisms were associated with CHD in offspring, and its haplotypes have affected the occurrence of CHD. Furthermore, given the complexity and heterogeneity of CHD, the mechanisms by which these factors influence offspring cardiac development remain unknown, and studies in larger samples in an ethnically diverse population are needed.

title: History of induced abortion and the risk of preterm birth: a retrospective cohort study

description: To explore the relationship between a history of induced abortion and follow-up preterm birth. We performed a retrospective cohort study of 27,176 women aged 19 to 48 years old in the city of Dongguan. Participants were divided into two groups according to the history of induced abortion. We used log-binomial regression to estimate adjusted risk ratios of preterm birth (gestation at less than 37 weeks) and early preterm birth (gestation at less than 34 weeks) for women with a history of induced abortion. Four models adjusted for different baseline data were used to verify the stability of the results. We also performed a subgroup analysis and mediation effect analysis to control for the influence of confounding factors and analyzed the relationship between the number of abortions and subsequent preterm birth. Our study included 2,985 women who had undergone a prior induced abortion. Women who reported having a prior induced abortion were more likely to have preterm births before 37 weeks and 34 weeks, with risk ratios of 1.18 (95% CI 1.02–1.36) and 1.65 (95% CI 1.23–2.21), respectively. The above associations were stable in all models. We also found that a history of induced abortion was independently associated with a higher risk of preterm birth and early preterm birth in the subgroups. After controlling for the indirect effect of demographic data, the direct effect of abortion history on follow-up preterm delivery was still significantly different. The higher the number of abortions, the greater the risk of subsequent preterm birth. This study suggests that induced abortion increases the risk of subsequent preterm birth.
