Wu Q, Xi F, Luo P, Dong T, Jiang H, Luo Q. Development and validation of a nomogram for predicting placenta accreta spectrum in pregnancies with one previous cesarean delivery. Int J Gynaecol Obstet 2024. [PMID: 38832362 DOI: 10.1002/ijgo.15702] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Revised: 03/27/2024] [Accepted: 05/11/2024] [Indexed: 06/05/2024]
Abstract
OBJECTIVE This study aimed to develop and validate a prenatal nomogram to predict the risk of placenta accreta spectrum (PAS) in women with one previous cesarean delivery. METHODS This retrospective study enrolled 5157 pregnant women with one previous cesarean delivery in China from January 2021 to January 2023. The nomogram was developed from a training cohort of 3612 pregnant women and tested on a validation cohort of 1545 pregnant women. Multivariate regression analysis was performed using the minimum value of the Akaike information criterion to select prognostic factors that can be included in the nomogram. We evaluated the nomogram by the area under the receiver operating characteristic (ROC) curve, calibration curves, and the decision curve analysis (DCA). RESULTS PAS occurred in 199 (5.51%) and 80 (5.18%) patients in the training and validation cohorts, respectively. Backward stepwise algorithms in the multivariable logistic regression model determined abortion, hypertensive disorders complicating pregnancy, fetal position, and placenta previa as relevant PAS predictors. The area under the ROC curve for the nomogram was 0.770 (95% confidence interval [CI] 0.733-0.807) and 0.791 (95% CI 0.730-0.853) for the training and validation cohorts, respectively. The calibration curves indicated that the nomogram's prediction probability was consistent with the actual probability. The DCA curve revealed that the nomogram has potential clinical benefit. CONCLUSION A prenatal nomogram was developed for PAS in our study, which helped obstetricians determine potential patients with PAS and make sufficient preoperative preparation to reduce maternal and neonatal complications.

Abstract
OBJECTIVES To compare maternal characteristics and outcomes among patients having major placenta previa (PP) with and without previous cesarean section (CS). And to determine if previous CS alone is a risk factor for associated adverse maternal outcomes in these patients. MATERIALS AND METHODS This is a retrospective analysis including two groups of major PP patients, with previous CS (n = 184) and without CS (n = 115); who were admitted to Abha Maternity and Children's Hospital over the last ten-years (January 2012-December 2021), Aseer region, Saudi Arabia. RESULTS Compared to those without previous CS, major PP patients with previous CS had significantly advanced ages with higher mean numbers of gravidity and parity, but significantly less rates of previous uterine surgery and IVF pregnancies. Moreover, they were more likely to acquire higher rates of adverse maternal outcomes. In the same way, these patients had an increased Odds Ratios of cesarean hysterectomy (OR of 20.462), urinary tract injuries (OR of 12.361), associated PAS (OR of 4.375), moderate/ heavy intra-operative bleeding (OR of 2.153) and the need for transfusion of 3+ units of packed RBCs (OR of 1.849). CONCLUSION (1) Patients with combined existence of major PP and previous CS had significantly higher rates of adverse maternal outcomes (2) Alone, prior CS in major PP patients increased the Odds Ratios of cesarean hysterectomy, urinary tract injuries, diagnosis of PAS, excessive intra-operative bleeding and repeated packed RBCs transfusions. (3) Among our PP patients with previous CS, the increased rate and OR of PAS diagnosis could in-part explain the adverse maternal outcomes.

Abstract
Placenta previa poses significant risks to maternal and perinatal health, yet its management remains challenging. This comprehensive review synthesizes current evidence on maternal and perinatal outcomes in placenta previa, addressing its epidemiology, pathophysiology, diagnosis, and management strategies. Placenta previa complicates pregnancies, with increasing incidence linked to factors such as advanced maternal age and rising cesarean rates. Maternal complications, including hemorrhage and placenta accreta spectrum disorders, pose substantial risks. At the same time, perinatal outcomes are marked by increased rates of preterm birth, intrauterine growth restriction, and neonatal morbidity and mortality. Timely diagnosis and appropriate management, including antenatal corticosteroids and multidisciplinary care, are critical for optimizing outcomes. Future research should focus on improving diagnostic methods, evaluating novel interventions, and assessing long-term neurodevelopmental outcomes. This review underscores the importance of informed clinical practice and ongoing research efforts to enhance outcomes for women and infants affected by placenta previa.

Characteristics and treatment for severe postpartum haemorrhage in different midwifery hospitals in one district of Beijing in China: an institution-based, retrospective cohort study. BMJ Open 2024; 14:e077709. [PMID: 38569676 PMCID: PMC11146356 DOI: 10.1136/bmjopen-2023-077709] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Accepted: 12/08/2023] [Indexed: 04/05/2024] Open
Abstract
OBJECTIVE To identify the characteristics and treatment approaches for patients with severe postpartum haemorrhage (SPPH) in various midwifery institutions in one district in Beijing, especially those without identifiable antenatal PPH high-risk factors, to improve regional SPPH rescue capacity. DESIGN Retrospective cohort study. SETTING This study was conducted at 9 tertiary-level hospitals and 10 secondary-level hospitals in Haidian district of Beijing from January 2019 to December 2022. PARTICIPANTS The major inclusion criterion was SPPH with blood loss ≥1500 mL or needing a packed blood product transfusion ≥1000 mL within 24 hours after birth. A total of 324 mothers with SPPH were reported to the Regional Obstetric Quality Control Office from 19 midwifery hospitals. OUTCOME MEASURES The pregnancy characteristics collected included age at delivery, gestational weeks at delivery, height, parity, delivery mode, antenatal PPH high-risk factors, aetiology of PPH, bleeding amount, PPH complications, transfusion volume and PPH management. SPPH characteristics were compared between two levels of midwifery hospitals and their association with antenatal PPH high-risk factors was determined. RESULTS SPPH was observed in 324 mothers out of 106 697 mothers in the 4 years. There were 74.4% and 23.9% cases of SPPH without detectable antenatal PPH high-risk factors in secondary and tertiary midwifery hospitals, respectively. Primary uterine atony was the leading cause of SPPH in secondary midwifery hospitals, whereas placental-associated disorders were the leading causes in tertiary institutions. Rates of red blood cell transfusion over 10 units, unscheduled returns to the operating room and adverse PPH complications were higher in patients without antenatal PPH high-risk factors. Secondary hospitals had significantly higher rates of trauma compared with tertiary institutions. CONCLUSION Examining SPPH cases at various institutional levels offers a more comprehensive view of regional SPPH management and enhances targeted training in this area.

Efficacy and safety of prophylactic balloon occlusion in the management of placenta accreta spectrum disorder: a retrospective cohort study. BMC Womens Health 2024; 24:208. [PMID: 38561713 PMCID: PMC10986079 DOI: 10.1186/s12905-024-03049-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Accepted: 03/25/2024] [Indexed: 04/04/2024] Open
Abstract
OBJECTIVE Placenta accreta spectrum disorder (PAS) is a serious obstetric complication associated with significant maternal morbidity and mortality. Prophylactic balloon occlusion (PBO), as an intravascular interventional therapies, has emerged as a potential management strategy for controlling massive hemorrhage in patients with PAS. However, current evidence about the clinical application of PBO in PAS patients are still controversial. This study aimed to evaluate the effectiveness and safety of PBO in the management of PAS. METHODS A retrospective cohort study including PAS patients underwent cesarean delivery was conducted in a tertiary hospital from January 2015 to March 2022. Included PAS patients were further divided into balloon and control groups by whether PBO was performed. Groups were compared for demographic characteristics, intraoperative and postoperative parameters, maternal and neonatal outcomes, PBO-related complication and follow up outcomes. Additionally, multivariate-logistic regression analysis was performed to determine the definitive associations between PBO and risk of massive hemorrhage and hysterectomy. RESULTS A total of 285 PAS patients met the inclusion criteria were included, of which 57 PAS patients underwent PBO (PBO group) and 228 women performed cesarean section (CS) without PBO (control group). Irrespective of the differences of baseline characteristics between the two groups, PBO intervention did not reduce the blood loss, hysterectomy rate and postoperative hospital stay, but it prolonged the operation time and increased the cost of hospitalization (All P < 0.05) Additionally, there were no significant differences in postoperative complications, neonatal outcomes, and follow-up outcomes(All P > 0.05). In particular, patients undergoing PBO were more likely to develop the venous thrombosis postoperatively (P = 0.001). However, multivariate logistic regression analysis showed that PBO significantly decreased the risk of massive hemorrhage (OR 0.289, 95%CI:0.109-0.766, P = 0.013). The grade of PAS and MRI with S2 invasion were the significant risk factors affecting massive hemorrhage(OR:6.232 and OR:5.380, P<0.001). CONCLUSION PBO has the potential to reduce massive hemorrhage in PAS patients undergoing CS. Obstetricians should, however, be aware of potential complications arising from the PBO. Additionally, MRI with S2 invasion and PAS grade will be useful to identify PAS patients who at high risk and may benefit from PBO. In brief, PBO seem to be a promising alternative for management of PAS, yet well-designed randomized controlled trials are needed to convincingly demonstrate its benefits and triage the necessity of PBO.

Sci Rep 2024; 14:2803.

Abstract
Placenta accreta spectrum (PAS) presents a significant obstetric challenge, associated with considerable maternal and fetal-neonatal morbidity and mortality. Nevertheless, it is imperative to acknowledge that a noteworthy subset of PAS cases remains undetected until the time of delivery, thereby contributing to an augmented incidence of morbidity among the affected individuals. The delayed identification of PAS not only hinders timely intervention but also exacerbates the associated health risks for both the maternal and fetal outcomes. This underscores the urgency to innovate strategies for early PAS diagnosis. In this study, we aimed to explore plasma proteins as potential diagnostic biomarkers for PAS. Integrated transcriptome and proteomic analyses were conducted to establish a novel diagnostic approach. A cohort of 15 pregnant women diagnosed with PAS and delivering at Inonu University Faculty of Medicine between 01/04/2021 and 01/01/2023, along with a matched control group of 15 pregnant women without PAS complications, were enrolled. Plasma protein identification utilized enzymatic digestion and liquid chromatography-tandem mass spectrometry techniques. Proteomic analysis identified 228 plasma proteins, of which 85 showed significant differences (P < 0.001) between PAS and control cases. We refined this to a set of 20 proteins for model construction, resulting in a highly accurate classification model (96.9% accuracy). Notable associations were observed for proteins encoded by P01859 (Immunoglobulin heavy constant gamma 2), P02538 (Keratin type II cytoskeletal 6A), P29622 [Kallistatin (also known as Serpin A4)], P17900 (Ganglioside GM2 activator Calmodulin-like protein 5), and P01619 (Immunoglobulin kappa variable 3-20), with fold changes indicating their relevance in distinguishing PAS from control groups. In conclusion, our study has identified novel plasma proteins that could serve as potential biomarkers for early diagnosis of PAS in pregnant women. Further research and validation in larger PAS cohorts are necessary to determine the clinical utility and reliability of these proteomic biomarkers for diagnosing PAS.

A cost-effectiveness analysis of intrauterine spacers used to prevent the formation of intrauterine adhesions following endometrial cavity surgery. J Med Econ 2024; 27:170-183. [PMID: 38131367 DOI: 10.1080/13696998.2023.2298584] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Accepted: 12/20/2023] [Indexed: 12/23/2023]
Abstract
AIM To assess, from a United States (US) payer's perspective, the cost-effectiveness of gels designed to separate the endometrial surfaces (intrauterine spacers) placed following intrauterine surgery. MATERIALS AND METHODS A decision tree model was developed to estimate the cost-effectiveness of intrauterine spacers used to facilitate endometrial repair and prevent the formation (primary prevention) and reformation (secondary prevention) of intrauterine adhesions (IUAs) and associated pregnancy- and birth-related adverse outcomes. Event rates and costs were extrapolated from data available in the existing literature. Sensitivity analyses were conducted to corroborate the base case results. RESULTS In this model, using intrauterine spacers for adhesion prevention led to net cost savings for US payers of $2,905 per patient over a 3.5-year time horizon. These savings were driven by the direct benefit of preventing procedures associated with IUA formation ($2,162 net savings) and the indirect benefit of preventing pregnancy-related complications often associated with IUA formation ($3,002). These factors offset the incremental cost of intrauterine spacer use of $1,539 based on an assumed price of $1,800 and the related increase in normal deliveries of $931. Model outcomes were sensitive to the probability of preterm and normal deliveries. Budget impact analyses show overall cost savings of $19.96 per initial member within a US healthcare plan, translating to $20 million over a 5-year time horizon for a one-million-member plan. LIMITATIONS There are no available data on the effects of intrauterine spacers or IUAs on patients' quality of life. Resultingly, the model could not evaluate patients' utility related to treatment with or without intrauterine spacers and instead focused on costs and events avoided. CONCLUSION This analysis robustly demonstrated that intrauterine spacers would be cost-saving to healthcare payers, including both per-patient and per-plan member, through a reduction in IUAs and improvements to patients' pregnancy-related outcomes.

Abstract
OBJECTIVE The primary objective of this study was to assess the risk of severe maternal morbidity (SMM) experienced by patients residing in rural communities when delivered by a multidisciplinary team within a single urban academic center for placenta accreta spectrum (PAS). Subsequently, we aimed to determine a distance-dependent relationship between PAS morbidity and distance travelled by patients in rural communities. STUDY DESIGN This was a retrospective cohort study of patients who had PAS histopathological confirmation and delivery at our institution from 2005 to 2022. Our objective was to determine the relationship between patient locations (rural vs. urban) and maternal morbidity associated with PAS delivery. Sociogeographic determination of rurality was determined using the National Center for Health Statistics and most recent national census population data. Distance travelled was calculated by patient zip code to our PAS center using global positioning system data. RESULTS During the study period, 139 patients were managed by cesarean hysterectomy with confirmed PAS histopathology. Of these, 94 (67.6%) were from our urban community and 45 (32.4%) were from surrounding rural communities. The overall SMM incidence was 85% including blood transfusion and 17% without blood transfusions. Patient from rural communities were more likely to experience SMM (28.9 vs. 12.8%, p = 0.03) and this was driven by acute renal failure (1.1 vs. 11.1%, p = 0.01) and disseminated intravascular coagulopathy (1.1 vs. 8.8%, p = 0.04). SMM did reveal a distance-dependent relationship with SMM rates of 13.2, 33.3, and 43.8% at 50, 100, and 150 miles, respectively (p = 0.005). CONCLUSION Patients with PAS experience high rates of SMM. Geographic distance to a PAS center appears to significantly impact the overall morbidity a patient experiences. Further research is warranted to address this disparity and optimize patient outcomes for patients in rural communities KEY POINTS: · Patients from rural communities experience greater SMM in the setting of PAS.. · Intraoperative outcomes and interventions were similar, regardless of patient location.. · SMM may be related to the distance travelled by patients in rural communities..
