Risk factors of severe postpartum hemorrhage in pregnant women with placenta previa or low-lying placenta: a retrospective cohort study

BackgroundThe severe postpartum hemorrhage (SPPH) leads to dangerous maternal conditions, and its rate is still increasing and the trend in related risk factors is changing. Placenta-related problems remain the high-risk factor for SPPH. The object is to investigate the prevalence and the risk factors of the severe postpartum hemorrhage in pregnant women with placenta previa or low-lying placenta.MethodA retrospective analysis of pregnant women with placenta previa or low-lying placenta after 28 weeks gestation from May 2018 to May 2023 in the Peking Union Medical College Hospital was conducted. The primary outcome was severe postpartum hemorrhage defined as blood loss ≥ 1000 mL within 24 h of childbirth, or with signs or symptoms of low blood volume requiring transfusion of ≥ 4U of red blood cells. Univariate and multivariate logistic regression were used to identify potential risk factors of severe postpartum hemorrhage and receiver operating curve to evaluate the prediction performance.ResultsOf the 14,964 women, 201 met the inclusive criteria. SPPH rate was 1.3% overall and 18.9% in women with placenta previa or low-lying placenta. Weight (aOR = 0.93, 95%CI 0.87–0.99), increta or percreta placenta (aOR = 7.93, 95%CI 2.53–24.77) were the risk factors. The area under the ROC curve was 0.69(95%CI 0.59–0.80) for increta or percreta placenta alone, and 0.72(95%CI 0.62–0.82) for the combination of times of cesarean sections and anterior placenta.ConclusionsPlacenta accreta spectrum was the key independent risk factor of SPPH in women with placenta previa or low-lying placenta. Antenatal risk assessment of SPPH in these population is highly desirable and optimal intervention could be planned.

Exploring Effective Interventions for Postpartum Blues: A Review of Current Literature

Postpartum blues, or "baby blues," is a common condition affecting 50-80% of new mothers, marked by mood swings, tearfulness, anxiety, and fatigue. It typically emerges within the first two weeks postpartum and can impact mother-infant bonding and maternal well-being. Left untreated, it may escalate into more severe postpartum mood disorders. This review aims to assess the efficacy, accessibility, and feasibility of various interventions for postpartum blues, synthesizing current research to inform clinical practices and future studies. A systematic review of peer-reviewed articles from 2010 to 2024 was conducted using PubMed, CINAHL, and PsycINFO databases. Articles were selected based on relevance, methodological rigor, and focus on postpartum blues interventions. After screening, 72 articles met the inclusion criteria and were included in the final analysis. The review identified several effective interventions across different domains: Psychosocial intervention particularly peer support programs and cognitive-behavioral therapy (CBT) were most effective in reducing postpartum blues symptoms; Hormonal and pharmacological interventions, including neuroactive steroids and selective serotonin reuptake inhibitors (SSRIs), showed mixed but promising results; Nutritional interventions, particularly omega-3 supplementation, demonstrated significant preventive effects; Mind-body interventions, such as mindfulness-based therapies, were effective in improving mood stability; Technology-based interventions, including mobile health applications and AI-driven support, showed potential for scalable and accessible solutions. Psychosocial interventions provide the strongest evidence for managing postpartum blues, while emerging research on hormonal, nutritional, and technology-based interventions offers promising new directions. A personalized, multimodal approach integrating these strategies is recommended for improving maternal mental health during the postpartum period.

Abstract Disclosure: H.A. Awadalla: None. A.N. Kiani: None. W. Taha: None. N.N. Solanki: None. A. Lattouf: None. A. Shermetaro: None. A. Taweel: None. Introduction: Sheehan's syndrome (SS) is a rare condition characterized by hypopituitarism resultingfrom ischemic necrosis of the pituitary gland due to severe postpartum hemorrhage.Patients may have hormonal insufficiencies, ranging from single pituitary hormoneinsufficiency to total hypopituitarism. The diagnosis of SS is often delayed due to itsnonspecific signs and symptoms, leading to many undiagnosed and untreated cases. Case Presentation:A 33-year-old African American female with a history of panhypopituitarism secondaryto Sheehan Syndrome presented with syncope, lightheadedness, and severehypoglycemia (blood glucose 12mg/dL). Despite regular food intake, she struggled withglycemic control, experiencing recurrent hypoglycemic episodes associated withnausea, vomiting, unintentional weight loss (25kg), and polydipsia/polyuria. Laboratoryfindings revealed low ACTH, sodium, cortisol, and elevated liver enzymes, consistentwith hypopituitarism. Cosyntropin stimulation test confirmed adrenal insufficiency. MRIshowed an empty sella. Initially treated with high-dose hydrocortisone, then transitionedto lower maintenance doses, she continued to experience glycemic fluctuations.Intravenous dextrose and insulin sliding scale were initiated. Upon discharge, she wasprescribed hydrocortisone and levothyroxine. Despite adjustments, hypoglycemiapersisted, managed with dietary modifications. This case underscores the challenges inmanaging Sheehan Syndrome-associated panhypopituitarism and the need for tailoredtreatment approaches to achieve metabolic stability. Conclusion: This case underscores the complexities of managing panhypopituitarism secondary toSheehan syndrome, emphasizing the importance of comprehensive hormonalreplacement therapy and thorough monitoring to achieve symptom control andmetabolic stability. Tailored treatment regimens and continuous assessments arecrucial to addressing individual hormone deficiencies and preventing associatedcomplications effectively in these patients.

8144 Hypertension in Sheehan Syndrome: A Diagnostic Challenge

Abstract Disclosure: E. Ahsan: None. F.F. Foo: None. C. Lesniak: None. M. Akula: None. K. Hu: None. R. Ong: None. K. Chalasani: None. J. Cheng: None. S. Holland: None. Introduction: Postpartum pituitary necrosis, commonly known as Sheehan syndrome (SS), is the term used to describe the necrosis of anterior pituitary gland cells that occurs after significant postpartum bleeding, hypovolemia, and shock. This typically occurs after delivery, during which the mother suffers significant blood loss. The pituitary gland fails to produce hormones due to this blood loss. Depending on the degree of tissue damage, SS can have an acute or chronic course, and patients may present with a wide range of clinical symptoms at diagnosis. Acute SS is associated with postpartum pituitary infarction, which can result in hypotension, shock, hypoglycemia, hyponatremia, headache, vision disturbances, unconsciousness, and an inability to lactate. We present a rare case of SS where the patient experienced hypertension instead of classic hypotension due to postpartum preeclampsia. Clinical Case: A 40-year-old female with no significant medical history presented to the hospital for scheduled induction of labor for polyhydramnios and underwent vacuum-assisted vaginal delivery and postpartum hysterectomy due to severe postpartum hemorrhage secondary to DIC. The postpartum course was also complicated by preeclampsia with severe features. Patients developed features like excessive fatigue, hypoglycemia, hyponatremia, hypothyroidism, polyuria, and failure of lactation, which were consistent with panhypopituitarism secondary to Sheehan syndrome. However, the patient was hypertensive to 145/91 before steroids were given. Labs were significant for serum sodium 116 mmol/L (135-145 mmol/L), FSH <0.7 mIU/mL (Follicular Phase: 2.5-10.2, Mid-cycle Peak: 3.1-17.7, Luteal Phase: 1.5-9.1, Postmenopausal: 23.0-116.3), LH <0.2 mIU/m (Follicular Phase: 1.9-12.5, Mid-Cycle Peak: 8.7-76.3, Luteal Phase: 0.5-16.9, Postmenopausal: 10.0-54.7), Prolactin: 2.4 ng/mL (Non-pregnant: 3.0-30.0, Pregnant: 10.0-209.0, Postmenopausal: 2.0-20.0), PM Cortisol on admission: 1.10 ug/dL (3.44-16.76 ug/dL), plasma ACTH 7 pg/mL( 6 - 50 pg/mL), TSH 0.430 uIU/mL (0.550 - 4.780 uIU/mL), FT4 0.59 ng/dL - 1.76 ng/dL). MRI of the brain pituitary showed- A 1.5 cm region of hypoenhancement and an additional 2 mm focus of hypoenhancement in the sella, findings represent evolving pituitary necrosis. The patient received 24 units of blood transfusion and hormone replacement therapy, followed by outpatient endocrinology follow-up. Clinical lessons: Although considerable blood loss causes hypotension in patients with SS, additional postpartum medical issues can sometimes result in atypical presentations. In our patient, postpartum preeclampsia caused hypertension. Identifying the atypical symptoms of SS is just as vital as identifying its typical features to prevent potentially fatal consequences.

Antenatal maternal serum biomarkers as a predictor for placenta accreta spectrum disorders

IntroductionPlacenta accreta spectrum (PAS) disorder, an abnormal adherence of the placenta to the uterine wall, with variable degrees of invasion, is a major cause of maternal morbidity and mortality associated with severe postpartum hemorrhage. PAS is diagnosed using ultrasonography or with magnetic resonance imaging; in many centers there is a lack of PAS diagnostic expertise in diagnosing. Hence, we investigated the performance of selected maternal plasma protein biomarkers, antithrombin-III (AT-3), plasminogen activator inhibitor-I (PAI-I), soluble vascular endothelial growth factor receptor-II (sVEGFR-2), and soluble Tie-II (sT-2) for prenatal screening in pregnancies at a high risk of PAS. MethodsThis prospective study, conducted in a tertiary hospital from September 2021 to May 2022, included pregnant women with placenta previa suspicious of PAS between 28 and 42 weeks of gestation. Four serum samples were collected from each woman to evaluate serum concentrations and compared between placenta previa (control) and PAS groups. The screening performances of the biomarkers were analyzed, and the best screening model for PAS was created. ResultsTwenty-two women with PAS and 18 with placenta previa alone were included (n = 40). The median concentrations of PAI-I, AT-3, sVEGFR-2, and sT-2 among the PAS group were 21.2, 6154.6, 7.5, and 12.8 ng/mL, respectively. The best screening model for PAS combined all four biomarkers with a history of cesarean delivery (77 % sensitivity, 89 % specificity, and an AUC of 0.87). DiscussionA combination of the four maternal serum biomarkers in women with a history of cesarean delivery presented the most promising model for prenatal screening of PAS. ConclusionA combination of the four maternal serum biomarkers with a history of cesarean delivery presented the most promising model for prenatal screening of PAS.

Hypertensive Disorders and Cardiovascular Severe Maternal Morbidity in the US, 2015-2019

The incidence of severe maternal morbidity (SMM)-and particularly cardiovascular SMM (cvSMM), the first cause of pregnancy-related mortality-has been rising in North America. Although hypertensive disorders of pregnancy (HDP) are common, their association with cvSMM specifically remains unclear. To assess the association between individual subtypes of HDP and cvSMM, in addition to overall SMM, in a large, nationally representative sample. A population-based cohort study using the United States National Inpatient Sample was conducted. Individuals with obstetric deliveries between 2015 and 2019 were included. Data analysis was performed from October 2023 to February 2024. HDP subtypes included gestational hypertension, chronic hypertension, preeclampsia without severe features, severe preeclampsia, and HELLP (hemolysis, elevated liver enzymes, and low platelet) syndrome. The primary outcome was a composite of cvSMM (including conditions such as pulmonary edema, stroke, and acute myocardial infarction) and the secondary outcome was a composite of overall SMM (including cvSMM and other conditions such as respiratory failure, severe postpartum hemorrhage, and sepsis). Adjusted risk ratios (aRRs) for the association between HDP subtypes and the outcomes were estimated using modified Poisson regression models adjusted for demographic and clinical characteristics. Among 15 714 940 obstetric deliveries, 2 045 089 (13.02%) had HDP, 23 445 (0.15%) were affected by cvSMM, and 282 160 (1.80%) were affected by SMM. The mean (SD) age of the cohort was of 29 (6) years. The incidence of cvSMM was higher in participants with HDP than those without HDP (0.48% [9770 of 2 045 089] vs 0.10% [13 680 of 13 669 851]; P < .001). Participants with HELLP syndrome had the highest risk for cvSMM (aRR, 17.55 [95% CI, 14.67-21.01]), followed by severe preeclampsia (aRR, 9.11 [95% CI, 8.26-10.04]), and chronic hypertension (aRR, 3.57 [95% CI, 3.15-4.05]). Although HDP subtypes were also associated with overall SMM, the association with HELLP syndrome (aRR, 9.94 [95% CI, 9.44-10.45]), severe preeclampsia (aRR, 3.66 [95% CI, 3.55-3.78]), and chronic hypertension (aRR, 1.96 [95% CI, 1.88-2.03]) was attenuated compared with cvSMM. In this cohort study, a graded relationship by severity characterized the association between HDP and cvSMM. Although all HDP subtypes were associated with an increased risk of overall SMM, the risk was more pronounced for cvSMM.

Maternal and Neonatal Consequences of Early Augmentation of Labor Among Women With Spontaneous Onset of Labor: A National Population-Based Study.

While some labor interventions are essential in preventing maternal and neonatal morbidity, there is little evidence to support systematic early augmentation of labor (EAL). Our objective was to assess the association between EAL and cesarean delivery rate, postpartum hemorrhage and adverse neonatal outcomes. Population-based study using data from the 2016 French Perinatal Survey. Women with a singleton cephalic fetus, delivering at term after a spontaneous labor were included. "EAL" was defined by artificial rupture of the membranes (AROM) and/or oxytocin within 1 h of admission and/or duration between interventions of less than 1 h. Women without EAL were women without labor augmentation or without EAL. The primary endpoint, cesarean delivery and the secondary endpoints were compared between women with and without EAL using univariate analysis. A multivariable logistic regression was adjusted on the suspected confounders and a propensity score approach was then performed. Among the 7196 women included, 1524 (21.2%) had EAL. Cesarean delivery rates were significantly higher in the EAL group compared with the no EAL group, 8.40% versus 6.15% (p < 0.01). EAL was associated with cesarean delivery in the multivariable analysis aOR 1.45 95% CI [1.15-1.82] and in the cohort matched on the propensity score, OR 1.56 [1.17-2.07]. EAL was not associated with severe postpartum hemorrhage, low 5-min Apgar score, low neonatal cord pH or transfer to NICU. EAL is frequent, involving one in five spontaneous laboring women in France. This practice is associated with an increased cesarean delivery risk.

Severe adverse maternal and neonatal outcomes according to the planned birth setting being midwife-led birth centers or obstetric-led units.

The establishment of midwife-led birth centers (MLBCs) is still being debated. The study aimed to compare severe adverse outcomes and mode of birth in low-risk women according to their birth planned in MLBCs or in obstetric-led units (OUs) in France. We used nationwide databases to select low-risk women at the start of care in labor in MLBCs (n = 1294) and in OUs (n = 5985). Using multilevel logistic regression, we compared severe adverse maternal and neonatal morbidity as a composite outcome and as individual outcomes. These include severe postpartum hemorrhage (≥1000 mL of blood loss), obstetrical anal sphincter injury, maternal admission to an intensive care unit, maternal death, a 5-minute Apgar score <7, neonatal resuscitation at birth, neonatal admission to an intensive care unit, and stillbirth or neonatal death. We also studied the mode of birth and the role of prophylactic administration of oxytocin at birth in the association between birth settings and severe postpartum hemorrhage. Severe adverse maternal and neonatal outcome indicated a slightly higher rate in women in MLBCs compared to OUs according to unadjusted analyses (4.6% in MLBCs vs. 3.4% in OUs; cOR 1.36; 95%CI [1.01-1.83]), but the difference was not significant between birth settings after adjustment (aOR 1.37 [0.92-2.05]). Severe neonatal morbidity alone was not different (1.7% vs. 1.6%; aOR 1.17 [0.55-2.47]). However, severe maternal morbidity was significantly higher in MLBCs than in OUs (3.0% vs. 1.9%; aOR 1.61 [1.09-2.39]), mainly explained by higher risks of severe postpartum hemorrhage (2.4 vs. 1.1%; aOR 2.37 [1.29-4.36]), with 2 out of 5 in MLBCs partly explained by the low use of prophylactic oxytocin. Cesarean and operative vaginal births were significantly decreased in women with a birth planned in MLBCs. In France, 3 to 4% of low-risk women experienced a severe adverse maternal or neonatal outcome regardless of the planned birth setting. Results were favorable for MLBCs in terms of mode of birth but not for severe postpartum hemorrhage, which could be partly addressed by revising practices of prophylactic administration of oxytocin.

Risk of cervical laceration in forceps vs vacuum delivery: Asystematic review and meta-analysis.

Cervical laceration is an obstetric injury associated with severe postpartum hemorrhage and subsequent spontaneous preterm birth. While operative vaginal delivery is a known risk factor for cervical laceration, it is unclear whether forceps and vacuum deliveries incur the same risk. The aim of this systematic review was to compare the risk of cervical laceration between operative instruments (forceps vs vacuum). Medline, Embase, Global Health, CENTRAL, Emcare, and Web of Science were searched from inception until August 2024 with terms related to operative vaginal delivery and cervical laceration. Studies comparing the risk of cervical laceration in individuals undergoing forceps or vacuum delivery were included. Two authors conducted screening, data extraction, and quality assessment of all studies. Random-effects models were used to pool risk ratios across studies and certainty of evidence was assessed using Cochrane methods and the GRADE approach. PROSPERO Registration Number CRD42023421890. Thirteen studies were eligible for inclusion, 3 randomized controlled trials (RCTs) and 10 observational studies. The overall rate of cervical laceration was 0.35% (990/284218 births) where 1.04% of forceps deliveries (456/43817) were complicated by cervical laceration compared to 0.22% of vacuum deliveries (534/240401). The risk of cervical laceration was 2-5 fold greater in forceps deliveries than in vacuum deliveries: pooled unadjusted risk ratio [RR] 4.83, 95% confidence interval [CI] 1.56-14.98 among RCTs and pooled unadjusted RR 1.89, 95% CI 1.59-2.24 among observational studies. The overall quality of evidence was low to moderate mainly due to the lack of attention to confounding in the included literature. The GRADE assessment indicated that the certainty of evidence was very low for observational studies and moderate for RCTs. Low certainty of evidence indicates that forceps deliveries may be associated with an increased risk of cervical laceration compared to vacuum deliveries.

Maternal Complications After Laser Surgery for Twin-to-Twin Transfusion Syndrome, a Cohort Study.

To assess maternal complications after fetoscopic laser surgery (FLS) for the twin-to-twin transfusion syndrome (TTTS). All consecutive cases treated with FLS for TTTS between 2008 and 2021 at the Leiden University Medical Center (LUMC) were included. We allocated complications in three timeframes: "Admission for laser surgery," "pregnancy after laser," and "delivery and third stage of labor." Maternal complications were graded according to the Maternal and Fetal Adverse Event Terminology (MFAET) and for intra-abdominal hemorrhage, the Common Terminology Criteria for Adverse Events (CTCAE). In the study period, 637 mothers were treated for TTTS with FLS. There were 1559 occurrences of maternal complications. The rate of severe maternal complications (grade 3 or 4) was 8.0%. Severe complications consisted of six cases of severe intra-abdominal hemorrhage, nine cases of severe hemorrhage in pregnancy, one with severe chorioamnionitis, 10 with severe preeclampsia/HELLP syndrome, and 25 with a severe postpartum hemorrhage. Even though it is the gold standard for treating TTTS, FLS comes at a risk to the mother which should not be neglected. And even though not all complications have serious consequences to the mother, the severe maternal complication rate of 8.0% should be added to the inherent risks for the fetus, and should be discussed with patients eligible for surgery in order to make an informed decision on treatment options.

Cavitating Osmotic Demyelination Syndrome Following Correction of Chronic Hyponatremia in Sheehan’s Syndrome: A Novel Case Report

Introduction Rapid correction of hyponatremia can result in osmotic demyelination syndrome (ODS). Sheehan’s syndrome, a rare pituitary disorder caused by severe postpartum hemorrhage, is a potential cause of chronic hyponatremia. This case report describes a rare progression of extrapontine myelinolysis to central pontine myelinolysis, ultimately leading to ODS, following the correction of chronic hyponatremia associated with Sheehan’s syndrome. Notably, this event occurred a decade after the initial postpartum hemorrhage due to placenta previa. Case Report A 40-year-old woman from rural West Bengal, India, presented in a comatose state after five years of progressively worsening symptoms, including fatigue, gastrointestinal disturbances, cold intolerance, hair loss, and severe apathy, which had been misdiagnosed as psychogenic and treated with selective serotonin reuptake inhibitors. Two days before her admission to our hospital, she was diagnosed with a lower respiratory tract infection, dehydration, and severe hyponatremia (118 mEq/L) at a local private healthcare facility. Despite treatment with 3% sodium chloride and intravenous antibiotics, her condition deteriorated, prompting her transfer. At the time of hospitalization, the patient was diagnosed with chronic hyponatremia and hypopituitarism consistent with Sheehan’s syndrome. This condition was attributed to a severe postpartum hemorrhage that occurred a decade prior, resulting from placenta previa. Initial MRI revealed extrapontine myelinolysis, and the correction of her “compensated” hyponatremia was identified as the cause of her neurological decline. Follow-up MRIs at 7 and 14 weeks confirmed the development of cavitating ODS. Discussion This case highlights several key points: First, even a relatively gradual correction of hyponatremia can precipitate ODS, especially in patients with chronic conditions like Sheehan’s syndrome. Second, it underscores the importance of meticulous management of chronic hyponatremia to prevent severe neurological outcomes. Third, it illustrates the diagnostic challenges of differentiating Sheehan’s syndrome from primary psychiatric disorders, particularly in low-resource settings where the syndrome remains prevalent. The case also emphasizes the need for awareness among healthcare providers about the potential for severe complications arising from even minor corrections in serum sodium levels in such patients.

Risk of adverse perinatal outcomes with violence in pregnancy.

To examine the association between physical, sexual, or physiological harm in pregnancy and perinatal outcomes in a large, contemporary birth cohort. This retrospective cohort study used California-linked vital statistics and hospital discharge data from 2016 to 2020. We included singleton, non-anomalous births with a gestational age of 23-42weeks. Violence in pregnancy was identified using International Classification of Disease, Tenth Revision (ICD-10) codes. Chi-square tests and multivariable Poisson regression models were used to evaluate associations of violence in pregnancy with perinatal outcomes. A total of 1,728,478 pregnancies met inclusion criteria, of which 3,457 (0.2%) had reported violence in pregnancy. Compared to those without violence in pregnancy, individuals who experienced violence had an increased risk of non-severe hypertensive disorders (aRR = 1.36, 95% CI 1.22, 1.51), preeclampsia with severe features (aRR = 1.34; 95% CI 1.11, 1.61), chorioamnionitis (aRR = 1.68; 95% CI 1.48, 1.91), anemia (aRR = 1.59; 95% CI 1.50, 1.68), antepartum hemorrhage (aRR = 2.17; 95% CI 1.19, 3.95), and postpartum hemorrhage (aRR = 1.65; 95% CI 1.48, 1.85). Violence in pregnancy was also associated with increased risk of Apgar score < 7 at 5 min (aRR = 1.37; 95% CI 1.11, 1.71) and neonatal hypoglycemia (aRR = 1.26; 95% CI 1.07, 1.48). Violence experienced in pregnancy is associated with an increased risk of adverse perinatal outcomes. Understanding how universal screening and early recognition of violence in pregnancy may reduce disparities in maternal morbidity for this understudied population is critical.

Nomogram based on clinical characteristics and ultrasound indicators for predicting severe postpartum hemorrhage in patients with anterior placenta previa combined with previous cesarean section: a retrospective case-control study

BackgroundPlacental accreta spectrum disorders (PAS) are a high-risk group for severe postpartum hemorrhage (SPPH), with the incidence of PAS increasing annually. Given that cesarean section and anterior placenta previa are the primary risk factors for PAS, therefore, our study aims to investigate the predictive value of clinical characteristics and ultrasound indicators for SPPH in patients with anterior placenta previa combined with previous cesarean section, providing a theoretical basis for early prediction of SPPH.MethodsA total of 450 patients with anterior placenta previa combined with previous cesarean section were retrospectively analyzed at Shengjing Hospital affiliated with China Medical University between January 2018 and March 2022. Clinical data and ultrasound indicators were collected. Patients were categorized into SPPH (blood loss >2000mL, 182 cases) and non-SPPH (blood loss ≤ 2000mL, 268 cases) groups based on the blood loss within 24 h postpartum. The population was randomly divided into training and validation cohorts at a 7:3 ratio. LASSO and multifactorial logistic regression analyses were utilized to identify independent risk factors for SPPH. Accordingly, a nomogram prediction model was constructed, the predictive performance was assessed using receiver operating characteristic (ROC) curves, calibration curves and decision curve analysis (DCA).ResultsAmong the 450 patients, 182 experienced SPPH (incidence rate, 40.44%). Preoperative systemic immune-inflammatory index, preoperative D-dimer level, preoperative placenta accreta spectrum ultrasound scoring system (PASUSS) score, and one-step-conservative surgery were identified as independent risk factors for SPPH in patients with anterior placenta previa combined with previous cesarean section. A nomogram was constructed based on these factors. The areas under the ROC curves for the training and validation cohorts were 0.844 (95%CI: 0.801–0.888) and 0.863 (95%CI: 0.803–0.923), respectively. Calibration curves and DCA indicated that this nomogram demonstrated good predictive accuracy.ConclusionsThis nomogram presents an effective and convenient prediction model for identifying SPPH in patients with anterior placenta previa combined with previous cesarean section. It can guide surgical planning and improve prognosis.

Perinatal Intimate Partner Violence and Maternal-Infant Bonding in Women With Anxiety Symptoms in Pakistan: The Moderating Role of Breastfeeding.

Intimate partner violence (IPV) during the perinatal period can negatively affect both a woman's health and the bonding with her infant. Research on IPV among pregnant women experiencing psychological distress in South Asia is limited. We examined associations between perinatal exposure to IPV and postnatal maternal-infant bonding in Pakistani women with symptoms of anxiety and assessed if breastfeeding practices moderated these associations. Postnatal data were collected from 720 Pakistani women who reported at least mild levels of anxiety symptoms in pregnancy. We performed Poisson regression with robust variance analyses to examine the associations between IPV during pregnancy or within 6 weeks after delivery (i.e., the perinatal period) and maternal-infant bonding. Interaction terms between IPV and breastfeeding practices were included in the analytic models to examine the moderating effects. About 27% of women were exposed to at least one type of perinatal IPV. Women who were exposed to IPV were more likely to have moderate to severe postpartum anxiety (n = 57, 28.9% of IPV-exposed women), compared to those without IPV (n = 65, 12.4% of unexposed women; p value < .001). Compared to women not reporting IPV, women exposed to any IPV showed a 38% increase in Postpartum Bonding Questionnaire scores, suggesting higher likelihood of impaired bonding (risk ratio [RR] = 1.38, 95% confidence interval [CI] [1.21, 1.56]). Among women who initiated breastfeeding later than 1 hr post-delivery, IPV was associated with impaired bonding (RR = 1.09, 95% CI [1.06, 1.20]), whereas no association was present for women who initiated breastfeeding within 1 hr (RR = 1.03, 95% CI [0.98, 1.08]). In addition to the efforts to reduce IPV, encouraging IPV-exposed women to adhere to the breastfeeding guidelines (e.g., early breastfeeding) may enhance maternal-infant bonding.

Incidence and Risk Factors for Severe Postpartum Hemorrhage in Women With Anterior Low-Lying or Previa Placenta and Prior Cesarean: Prospective Population-Based Study

Incidence and Risk Factors for Severe Postpartum Hemorrhage in Women With Anterior Low-Lying or Previa Placenta and Prior Cesarean: Prospective Population-Based Study

Relationship between maternal postpartum depression, fatigue, sleep quality and infant growth: A cross-sectional study.

Current research separately analyzed the connection between postpartum depression, fatigue, sleep and infant development. However, depression, fatigue and sleep quality often coexisted as adverse symptoms in postpartum women and influenced infant development together. This study explored the maternal postpartum symptoms on infant growth. Our study included 224 pairs of singleton full-term mothers and their infants who underwent routine pediatric outpatient clinics. Latent profile analysis was applied to identify the latent classes based on mothers' postpartum depression, fatigue and sleep profile characteristics. We evaluated the maternal adverse symptoms and infant development using multivariable logistic regressions. Totally, 224 pairs of eligible mothers (28.85 ± 4.43 years) and infants (30.93 ± 3.26 days) participated in this study. Latent profile analysis identified 3 latent groups: mild (58.04%), moderate (34.37%), and severe (7.59%) postpartum adverse symptoms. Postpartum adverse symptoms were associated with delayed development in the baby's motor level (χ2 = 6.572, p = .037) and weight-for-length (χ2 = 9.652, p = .008). After controlling for mother and infant related factors, postpartum adverse symptoms remained a risk factor for infant motor level (odds ratio [OR]: 4.35; 95% confidence interval [CI]: 1.25-15.08) and weight-for-length (OR: 5.53; 95% CI: 1.55-19.74). Maternal postpartum depression, fatigue and sleep quality are associated with infant development. Clinically, mothers with these symptoms should be intervened timely to avoid the aggravation of maternal symptoms, which affect baby's development.

Racial/ethnic differences in pre-pregnancy conditions and adverse maternal outcomes in the nuMoM2b cohort: A population-based cohort study.

To determine how pre-existing conditions contribute to racial disparities in adverse maternal outcomes and incorporate these conditions into models to improve risk prediction for racial minority subgroups. We used data from the "Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-be (nuMoM2b)" observational cohort study. We defined multimorbidity as the co-occurrence of two or more pre-pregnancy conditions. The primary outcomes of interest were severe preeclampsia, postpartum readmission, and blood transfusion during pregnancy or up to 14 days postpartum. We used weighted Poisson regression with robust variance to estimate adjusted risk ratios and 95% confidence intervals, and we used mediation analysis to evaluate the contribution of the combined effects of pre-pregnancy conditions to racial/ethnic disparities. We also evaluated the predictive performance of our regression models by racial subgroup using the area under the receiver operating characteristic curve (AUC) metric. In the nuMoM2b cohort (n = 8729), accounting for pre-existing conditions attenuated the association between non-Hispanic Black race/ethnicity and risk of severe preeclampsia. Cardiovascular and kidney conditions were associated with risk for severe preeclampsia among all women (aRR, 1.77; CI, 1.61-1.96, and aRR, 1.27; CI, 1.03-1.56 respectively). The mediation analysis results were not statistically significant; however, cardiovascular conditions explained 36.6% of the association between non-Hispanic Black race/ethnicity and severe preeclampsia (p = 0.07). The addition of pre-pregnancy conditions increased model performance for the prediction of severe preeclampsia. Pre-existing conditions may explain some of the association between non-Hispanic Black race/ethnicity and severe preeclampsia. Specific pre-pregnancy conditions were associated with adverse maternal outcomes and the incorporation of comorbidities improved the performance of most risk prediction models.

Prolonged second stage of labor and risk of postpartum hemorrhage in nullipara with epidural anesthesia and vaginal delivery: A cohort study with propensity score analysis.

To conduct an analysis using propensity score methods, exploring the association between a prolonged second stage (>3 h) and the risk of postpartum hemorrhage (PPH) in a diverse population. We conducted a prospective cohort study involving nullipara with epidural anesthesia and vaginal delivery, aged ≥18 years, presenting cephalically, and with a gestational age (GA) of ≥24 weeks at a tertiary maternity hospital in China (chictr.org.cn identifier: ChiCTR2200063094). Women undergoing emergency cesarean section in labor were excluded. The primary outcome was PPH, with secondary outcomes including severe postpartum hemorrhage and blood transfusion. We employed propensity score overlap weighting to analyze the association between prolonged second stage labor and PPH. The study included 3643 nullipara with epidural anesthesia, comprising 77 with a second stage of labor >3 h and 3566 with a second stage ≤3 h. Utilizing propensity score overlap weighting, there were no significant differences observed between the two groups regarding the risk of PPH (29.87% in >3 h group vs 17.64% in ≤3 h group; weighted odds ratio 1.01; 95% CI: 0.51-2.02). Subgroup interaction tests for PPH were not significant for assisted vaginal delivery, induction of labor, macrosomia, third-/fourth-degree perineal laceration, GA >41 weeks, twin pregnancies, episiotomy and GA >37 weeks. Sensitivity analysis did not reveal significant differences. This study did not find evidence supporting an increased risk of PPH associated with a second stage of labor lasting >3 h in our population, providing additional evidence for clinical practice.

Sheehan’s syndrome presenting with panhypopituitarism and central diabetes insipidus: a case report

BackgroundSheehan’s syndrome is a rare condition, which is classically characterized by anterior pituitary hypofunction following postpartum shock or hemorrhage. While diabetes insipidus (DI) is not commonly associated with Sheehan’s syndrome, we present a rare case of a multiparous female developing rapid-onset panhypopituitarism and DI following severe postpartum hemorrhage.Case presentationA previously healthy 39-year-old woman, gravida 5, para 4, presented with hypovolemic shock after vaginal delivery, attributed to severe postpartum hemorrhage, necessitating emergent hysterectomy. Although her shock episodes resolved during hospitalization, she developed intermittent fever, later diagnosed as adrenal insufficiency. Administration of hydrocortisone effectively resolved the fever. However, she subsequently developed diabetes insipidus. Diagnosis of Sheehan’s syndrome with central diabetes insipidus was confirmed through functional hormonal tests and MRI findings. Treatment consisted of hormone replacement therapy, with persistent panhypopituitarism noted during a ten-year follow-up period.ConclusionsSheehan’s syndrome is a rare complication of postpartum hemorrhage. Central diabetes insipidus should be suspected, although not commonly, while the patient presented polyuria and polydipsia. Besides, the potential necessity for long-term hormonal replacement therapy should be considered.

“Maternal and Perinatal Outcome in Preterm Placenta Praevia”

Introduction: Placenta previa (PP) is a significant cause of maternal and fetal morbidity and mortality worldwide. However, there is limited data from developing countries on the maternal and fetal outcomes and complications associated with placenta previa. Aim of the study: The aim of this study was to evaluate maternal and perinatal outcome in preterm placenta praevia. Methods: This prospective observational study was conducted in the Department of Gynae and Obstetrics of Dhaka Medical College Hospital, Dhaka, Bangladesh during the period from March 2010 to August 1010. Result: Total 66 patients were diagnosed with placenta previa. We found, the majority (42%) of participants were aged between 26-30 years and with lower socio-economic status significantly associated with higher prevalence due to lack of regular antenatal care. The majority were admitted at 35-37 weeks gestation, with the highest perinatal loss occurring before 30 weeks. Initial bleeding was generally small, and many presented with labor pain and anemia. Ultrasonography diagnosed 55% of cases, with cesarean sections frequently used, leading to better outcomes compared to vaginal deliveries. Severe postpartum complications like hemorrhage and urinary tract infections were common in more severe cases. Conclusion: Placenta previa is a major cause of maternal and perinatal morbidity and mortality. Early registration, regular antenatal care, early detection of high-risk cases, and timely referral to higher centers with good NICU services and blood bank facilities can help prevent these adverse outcomes.
