Abstract

Severe bleeding is the single most significant cause of maternal death world-wide. More than half of all maternal deaths occur within 24 hours of delivery, most commonly from excessive bleeding. It is estimated that worldwide, 140,000 women die of postpartum hemorrhage each year-one every 4 minutes (1). In addition to death, serious morbidity may follow postpartum hemorrhage. Sequelae include adult respiratory distress syndrome, coagulopathy, shock, loss of fertility, and pituitary necrosis (Sheehan syndrome). Although many risk factors have been associated with postpartum hemorrhage, it often occurs without warning. All obstetric units and practitioners must have the facilities, personnel, and equipment in place to manage this emergency properly. Clinical drills to enhance the management of maternal hemorrhage have been recommended by the Joint Commission on Accreditation of Healthcare Organizations (2). The purpose of this bulletin is to review the etiology, evaluation, and management of postpartum hemorrhage.

... In theory, a fixed-ratio transfusion approach is useful to mimic the replacement of whole blood specifically in emergency settings where diagnostic coagulation test results are not available. Currently, however, fixed transfusion ratios vary across PPH guidelines [94,95]. For PAS patients with PPH in particular there are no fixed ratio transfusions recommended in current guidelines. ...
... Allogenic donor blood transfusion was similar in both groups, but increased in the routine care group if emergency C-section was performed [102]. During massive bleeds, cell salvage may reduce the need for additional allogenic transfusion without increasing the risk of amniotic fluid embolism due to high quality filtering techniques [92,94,101,102]. In PAS, cell salvage systems can be prepared prior to surgery and should be used according to multimodal fluid, transfusion, and hemostatic/PPH protocols [94]. ...

“Placenta accreta spectrum” (PAS) is a rare but serious pregnancy condition where the placenta abnormally adheres to the uterine wall and fails to spontaneously release after delivery. When it occurs, PAS is associated with high maternal morbidity and mortality—as PAS management can be particularly challenging. This two-part review summarizes current evidence in PAS management, identifies its most challenging aspects, and offers evidence-based recommendations to improve management strategies and PAS outcomes. The first part of this two-part review highlighted the general anesthetic approach, surgical and interventional management strategies, specialized “centers of excellence,” and multidisciplinary PAS treatment teams. The high rates of PAS morbidity and mortality are often provoked by PAS-associated coagulopathies and peripartal hemorrhage (PPH). Anesthesiologists need to be prepared for massive blood loss, transfusion, and to manage potential coagulopathies. In this second part of this two-part review, we specifically reviewed the current literature pertaining to hemostatic changes, blood loss, transfusion management, and postpartum venous thromboembolism prophylaxis in PAS patients. Taken together, the two parts of this review provide a comprehensive survey of challenging aspects in PAS management for anesthesiologists.
... Considering the risk of morbidity and mortality associated with PPH, important management guidelines have been developed by different obstetrics and gynecology societies and healthcare regulatory bodies [21,60,[79][80][81]. All guidelines acknowledge risk factors and are consistent with preventive measures and recommendations for PPH management. ...
... For PPH caused by uterine atony, the guidelines recommend the administration of uterotonics for prevention and treatment of PPH and timely surgical management [21,[79][80][81]. Some minor inconsistencies are reported regarding the optimal regimens for uterotonics used and dosages depending on the particular uterotonics availability and country-related income and guidelines [18,[82][83][84]. ...

Postpartum hemorrhage (PPH) represents a critical emergency condition and the principal cause of maternal morbidity and mortality worldwide. It encompasses excessive bleeding following childbirth, which can arise from various causes. Prompt recognition and management are essential to mitigate severe outcomes and ensure maternal safety. The incidence of PPH in low- and middle-income countries (LMICs) is higher than in developed countries. Healthcare systems in developing countries face multiple challenges that may impact PPH management at policy, facility, and community levels. The mentioned barriers could be addressed by providing an empowering environment via the implementation of supportive policies, access to PPH care, planning supplies, allying strategies, providing training, and utilization of guidelines and algorithms for PPH management. Evidence-based international guidelines should serve as an integral part of appropriate management. On the other hand, LMICs have limited opportunities to implement the proposed international algorithms and guidelines. Therefore, some amendments based on the resource/expertise availability should be considered at the specific clinical site. This review summarizes and updates the accumulated knowledge on postpartum hemorrhage, focusing on challenging management options in developing countries. In many LMICs, maternal morbidity and mortality linked to PPH were improved after the implementation of standardized protocols and timely and purposeful interventions. International support in healthcare professionals’ training, enhancing resources, and the provision of an adapted evidence-based approach could assist in improving the management of PPH in LMICs. Refining our understanding of specific local circumstances, international support in specialists’ training, and the provision of evidence-based approaches may assist in improving the management of PPH in LMICs and contribute to safer childbirth.
... Moreover, the observational studies included, varied in their choice of control groups, with some comparing AID systems outcomes against initial visit metrics, the pregestational phase, the run-in period, or early pregnancy data, depending on the specific study design. These comparisons may not be directly comparable due to the physiological changes that occur during pregnancy, which can significantly influence glycaemic control and insulin sensitivity [49]. Furthermore, in cases where SD, SE, or 95% CIs were not reported, we approximated SD using available p-values or utilized values from comparable studies. ...

Aims To assess the efficacy and safety of automated insulin delivery (AID) systems compared to standard care in managing glycaemic control during pregnancy in women with Type 1 Diabetes Mellitus (T1DM). Methods We searched MEDLINE, Cochrane Library, registries and conference abstracts up to June 2024 for randomized controlled trials (RCTs) and observational studies comparing AID to standard care in pregnant women with T1DM. We conducted random effects meta-analyses for % of 24-h time in range of 63–140 mg/dL (TIR), time in hyperglycaemia (> 140 mg/dl and > 180 mg/dL), hypoglycaemia (< 63 mg/dl and < 54 mg/dL), total insulin dose (units/kg/day), glycemic variability (%), changes in HbA1c (%), maternal and fetal outcomes. Results Thirteen studies (450 participants) were included. AID significantly increased TIR (Mean difference, MD 7.01%, 95% CI 3.72–10.30) and reduced time in hyperglycaemia > 140 mg/dL and > 180 mg/dL (MD – 5.09%, 95% CI – 9.41 to – 0.78 and MD – 2.44%, 95% CI – 4.69 to – 0.20, respectively). Additionally, glycaemic variability was significantly reduced (MD – 1.66%, 95% CI – 2.73 to – 0.58). Other outcomes did not differ significantly. Conclusion AID systems effectively improve glycaemic control during pregnancy in women with T1DM by increasing TIR and reducing hyperglycaemia without any observed adverse short-term effects on maternal and fetal outcomes.
... Postpartum hemorrhage (PPH) remains the leading cause of maternal mortality globally and is a significant cause of maternal morbidity and mortality in the United States, accounting for 12.1% of maternal deaths. 1 Aside from mortality, PPH is associated with secondary complications such as shock, disseminated intravascular coagulation (DIC), respiratory distress syndrome, acute renal failure, and Sheehan syndrome. 2 Recent data suggest that PPH occurs in 3% of hospital deliveries in the United States, although rates vary substantially across patient populations. 3 Multiple studies within the United States have found that the incidence of PPH has increased over the past 20 years, although the etiology remains unclear. ...

Background: Postpartum hemorrhage (PPH) remains a significant cause of maternal morbidity and mortality around the world, with rates increasing in the United States. The objective of this study was to determine predictors of, and outcomes associated with, PPH at a Midwest academic health center. Methods: Demographic and clinical data were obtained from the electronic medical record on all consecutive delivering patients between May 1, 2020, and April 30, 2021. Associations between PPH and perinatal characteristics and outcomes were assessed using logistic regression models. A significance threshold of 0.05 was used for all comparisons. Results: Of the 2497 delivering patients during the study period, 437 (18%) experienced PPH. Chronic hypertension, gestational hypertension, and preeclampsia with and without severe features were all associated with increased odds of PPH (odds rations [ORs], respectively, 1.61 (95% CI:1.13–2.24, p = 0.006), 1.62 (95% CI 1.18–2.21, p = 0.003), 1.81 (95% CI 1.14–2.80, p ≤ 0.001), and 1.92 (95% CI 1.29–2.82, p = 0.009). There were also increased odds of PPH with type I diabetes: 2.83 (95% CI 1.45–5.30, p = 0.001), type II diabetes: 2.14 (95% CI 1.15–3.82, p = 0.012), twin delivery: 3.20 (95% CI 2.11–4.81, p ≤ 0.001), cesarean delivery: 5.66 (95% CI 4.53–7.09, p ≤ 0.001), and assisted vaginal delivery: 3.12 (95% CI1.95–4.88, p ≤ 0.001). Infants of mothers with PPH had high odds of NICU admission (CI = 1.34–2.07, p < 0.001) and hypoxic ischemic encephalopathy (CI = 1.64–7.14, p < 0.001). Conclusion: Our findings confirm previous literature that preexisting and pregnancy-related hypertension, diabetes mellitus, multiple gestation, cesarean delivery, and assisted vaginal delivery are important predictors of PPH. In addition, we found that neonates of mothers with PPH had more adverse outcomes. These results may help to inform clinical care as rates of PPH continue to rise in the United States.
... Concurrently, laceration repair is indicated in cases of genital tract trauma and curettage in case of retained placenta. Managing a persistent bleeding despite uterotonic agents in cases of uterine atony may require the use of intrauterine balloon systems with or without vacuum [8,9]. Surgical interventions like B-Lynch sutures, ligation of the uterine artery or the internal iliac artery as well as hysterectomy as ultima ratio have been the treatment for severe refractory PPH for many decades, especially peripartum hysterectomy is associated with high morbidity [10]. ...

Introduction: Postpartum hemorrhage (PPH) is the leading cause of peripartal maternal mortality and accounts for 25% of all maternal deaths worldwide. The most common reasons of PPH are uterine atony, retained placenta, or placenta accreta spectrum. Treatment of PPH depends on the etiology and corresponds to a stepwise approach, which follows the German, Austrian and Swiss guideline for the diagnosis and therapy of PPH in Switzerland. In severe ongoing PPH, hysterectomy has been the ultima ratio for many decades. Nowadays, interventional embolization of the pelvic arteries (PAE) has become a popular alternative. Besides being a highly effective minimally invasive method, PAE avoids hysterectomy with consecutively reduced morbidity and mortality. However, data on the long-term effects of PAE on fertility and menstrual cycle are scarce. Methods: We performed a monocentric study consisting of a retro- and a prospective part including all women who had undergone a PAE between 2012 and 2016 at University Hospital Zurich. Descriptive characteristics of patients and efficacy of PAE defined as cessation of bleeding were analyzed retrospectively. In the prospective part, all patients were contacted for a follow-up questionnaire regarding menstruation and fertility after embolization. Results: Twenty patients with PAE were evaluated. Our data showed a success rate of PAE in 95% of patients with PPH; only 1 patient needed a second, then successful, PAE. No patient needed a hysterectomy or any other surgical intervention. In our study, an association between mode of delivery and identified etiology of PPH is observed. After spontaneous delivery (n = 6), the main reason of severe PPH was retained placenta (n = 4), while after cesarean section (n = 14), uterine atony was identified in most cases (n = 8). Regarding menstruation after embolization, all women reported regular menstruation after the breastfeeding period (100%). The majority reported a regular pattern with a shorter or similar duration (73%) and lower or similar intensity (64%). Dysmenorrhea decreased in 67% of patients. Four patients planned another pregnancy, of whom only one had become pregnant with assisted reproductive technology and ended up in a miscarriage. Discussion: Our study confirms the efficacy of PAE in PPH, thus obviating complex surgical interventions and associated morbidity. The success of PAE does not depend on the primary cause of PPH. Our results may encourage the prompt decision to perform PAE in the management of severe PPH in case of failure of conservative management and help physicians in the post-interventional counseling regarding menstruation patterns and fertility.

Background: Uterine atony can be life-threatening for a pregnant woman in labor and bleeding after delivery. It is important to explore the risk factors that can cause uterine atony in order to detect it early and take preventive measures. This study aimed to explore the risk factors for causing uterine atony in postpartum hemorrhage patients at Dr. Mohammad Hoesin General Hospital, Palembang, Indonesia. Methods: This study was an analytic observational study with a case-control approach. A total of 52 subjects (13 case group subjects and 39 control group subjects) participated in this study. Risk factor analysis was carried out with the help of SPSS version 25 in univariate and bivariate. Results: Maternal age at delivery is associated with the risk of uterine atony in postpartum hemorrhage patients. Mothers aged less than 20 years or more than 35 years are at risk of experiencing uterine atony by 5.8 times more at risk than mothers aged 20-35 years. The risk factors for parity, prolonged labor, macrosomia, gemelli, hydramnios, induction of labor, history of postpartum hemorrhage, and type of delivery were not associated with uterine atony in postpartum hemorrhage patients, p>0.05. Conclusion: The age of delivery of mothers who are less than 20 years or more than 35 years is a risk factor for uterine atony in postpartum hemorrhage patients at Dr. Mohammad Hoesin General Hospital, Palembang, Indonesia.

Objective: The perinatal period represents a critical juncture in a woman's life marked by profound emotional, social, and physical changes. During this phase, there is a propensity for the exacerbation of pre-existing psychiatric symptoms or the emergence of new ones. Notably, there is often an uptick in psychiatric emergencies and presentations to emergency psychiatric departments among women in the perinatal period. This study aimed to retrospectively evaluate women accessing emergency psychiatric departments during pregnancy and the postpartum period, focusing on their presenting complaints, diagnoses, clinical trajectory, and factors influencing the decision for inpatient treatment. Material and Method: A retrospective review was conducted on the records of 11,419 women aged 18 to 45 who sought care at the Psychiatric Emergency Department of Bakirkoy Prof.Dr. Mazhar Osman Research and Training Hospital Hospital between July 2015 and July 2016. Results: Among them, the records of 163 women who were either pregnant or within one year postpartum were analyzed. Of the women accessing services during the perinatal period, 46% were pregnant, while 54% were in the postpartum phase. Additionally, 38.7% of these women presented to the psychiatric department for the first time. Distress and anxiety emerged as the most common reasons for seeking help. Interestingly, no significant differences were observed between the pregnancy and postpartum periods regarding presenting complaints and clinical progression. However, the incidence of psychotic disorders was notably higher during the postpartum period compared to pregnancy. Through logistic regression analysis involving pregnancy status, presenting complaints, and diagnoses, it was determined that the nature of the presenting complaint significantly influenced the decision for inpatient treatment. Notably, scepticism, agitation, and suicidal ideation were identified as the most prevalent complaints among women who required inpatient care. Conclusion: Mental health challenges during the perinatal period not only jeopardize the well-being of the woman but also impact the health of the infant. Detecting and addressing emergent psychiatric issues during this phase are pivotal for timely intervention and preventive measures.

Background Women with von Willebrand disease (VWD) often face diagnostic delays, leading to increased bleeds, stress, and healthcare use. The factors influencing these delays and their effects on gynecologic outcomes are not well understood. Objectives This study aimed to 1) identify the prevalence and predictors of diagnostic delays and loss to follow-up in women with VWD and 2) determine how these delays affect severe gynecologic bleeding, emergency visits, transfusions, and hysterectomies. Methods We conducted a single-center retrospective cohort study and included women aged ≥18 years diagnosed with VWD. Delayed diagnosis was defined as ≥3 bleeding events prior to VWD diagnosis, excluding easy bruising due to its subjectivity. Loss to follow-up was defined as ≥5 years since the last hematology visit. We used logistic regression for analysis. Results Among 178 diagnosed women (median age, 27 years), 71 (40%) experienced ≥3 bleeding events before diagnosis. The median time from the first bleeding event to VWD diagnosis was 14.2 years. Severe bleeding events significantly predicted diagnostic delays (adjusted odds ratio, 3.1; 95% CI, 1.5-6.2). Fifty-four (30%) women were lost to follow-up, with remote era of initial bleed and VWD type identified as significant predictors. Delays were associated with increased risks of hysterectomies (odds ratio, 2.7; 95% CI, 1.2-6.3) and other gynecologic procedures. Conclusion Delayed diagnosis and loss to follow-up in VWD are common even in a specialized Hemophilia Treatment Centre. Such delays lead to more severe bleeding and increased gynecologic interventions. Prompt diagnosis is paramount for better patient outcomes and reduced healthcare utilization.

Objective: To determine and compare pregnancy outcomes after bilateral uterine artery ligation (BUAL) or bilateral hypogastric artery ligation (BHAL) for postpartum hemorrhage (PPH). Material and methods: This retrospective cross-sectional study was conducted from January 2010 to June 2018 at a tertiary referral hospital. Patients who had undergone arterial ligation for PPH were included in the study. Patients who had undergone BUAL and BHAL were compared with a control group in terms of fertility and pregnancy outcomes. Results: A total of 156 patients were included, of whom 47 underwent BUAl, 59 underwent BHAL and 50 were in the control group. There was no significant difference between the groups in subsequent pregnancies in terms of the incidence of miscarriage, fetal growth restriction, preeclampsia, primary cesarean deliveries, and infertility (p>0.05). There was a significant difference between all groups in gestational age at birth and birthweight. Preterm birth was observed in 32.2% of patients in the BHAL group, and this rate was significantly higher than in the BUAL (12.8%) and control (6%) groups (p=0.001). Conclusion: PPH is a life-threatening obstetric problem. The effects of interventions performed to reduce pelvic blood flow in patients may lead to persistent problems, such as preterm birth and low birth weight in the next pregnancy. However, these interventions do not appear to affect the risk of miscarriage. In subsequent pregnancies of patients who received BHAL, special attention should be paid to preterm birth.

Background: Previous studies suggest an association between late pregnancy exposure to selective serotonin reuptake inhibitors (SSRIs) and serotonin norepinephrine reuptake inhibitors (SNRIs) and increased postpartum hemorrhage (PPH) risk. This is the first pregnancy registry study to compare PPH outcomes among women with psychiatric illness exposed or unexposed to SSRIs/SNRIs proximate to delivery. Methods: This study used data from the National Pregnancy Registry for Psychiatric Medications to evaluate the relationship between SSRI/SNRI exposure in late pregnancy and PPH risk. The sample included n = 953 participants with retrospectively collected medical record data on postpartum blood loss, n = 453 unexposed to SSRIs/SNRIs during pregnancy, and n = 500 exposed at least during the week of delivery. PPH was defined as an estimated blood loss ≥500 mL following vaginal delivery or ≥1,000 mL following cesarean section (C-section), with onset of excessive bleeding occurring within the first 24 hours postpartum. Univariate and multivariate logistic regression analyses were performed to determine odds ratios. Results: Overall PPH incidence was 13.1%. SSRI/SNRI exposure was associated with a PPH unadjusted odds ratio of 1.42 compared to no exposure (95% confidence interval [CI: 0.97, 2.08]) and an adjusted odds ratio of 1.33 (95% CI [0.90, 1.97]). When stratified by delivery type, the odds ratio following vaginal delivery among women exposed to SSRIs/SNRIs was 1.04 (95% CI [0.63, 1.70]) versus 2.31 (95% CI [1.25, 4.26]) for C-section delivery; the adjusted C-section odds ratio was 2.21 (95% CI [1.18, 4.13]). Conclusions: Although these findings align with accumulating evidence suggesting SSRI/SNRI exposure may confer a modestly increased risk of PPH, particularly after C-section, the study was underpowered to make definitive conclusions. These preliminary data highlight the need for further research with larger sample sizes. Nevertheless, the findings underscore the importance of greater clinical monitoring for PPH following C-section, especially in women who may have other known PPH risk factors and are exposed to SSRIs/SNRIs in late pregnancy.

Objective: To evaluate the risk factors for postpartum hemorrhage (PPH) according to the Robson Classification in a low-risk maternity hospital. Methods: We conducted retrospective cohort study by analyzing the medical records of pregnant women attended in a low-risk maternity hospital, during from November 2019 to November 2021. Variables analyzed were: maternal age, type of delivery, birth weight, parity, Robson Classification, and causes of PPH. We compared the occurrence of PPH between pregnant women with spontaneous (Groups 1 and 3) and with induction of labor (2a and 4a). Chi-square and Student t-tests were performed. Variables were compared using binary logistic regression. Results: There were 11,935 deliveries during the study period. According to Robson's Classification, 48.2% were classified as 1 and 3 (Group I: 5,750/11,935) and 26.1% as 2a and 4a (Group II: 3,124/11,935). Group II had higher prevalence of PPH than Group I (3.5 vs. 2.7%, p=0.028). Labor induction increased the occurrence of PPH by 18.8% (RR: 1.188, 95% CI: 1.02-1.36, p=0.030). Model including forceps delivery [x 2 (3)=10.6, OR: 7.26, 95%CI: 3.32-15.84, R 2 Nagelkerke: 0.011, p<0.001] and birth weight [x 2 (4)=59.0, OR: 1.001, 95%CI:1.001-1.001, R 2 Nagelkerke: 0.033, p<0.001] was the best for predicting PPH in patients classified as Robson 1, 3, 2a, and 4a. Birth weight was poor predictor of PPH (area under ROC curve: 0.612, p<0.001, 95%CI: 0.572-0.653). Conclusion: Robson Classification 2a and 4a showed the highest rates of postpartum hemorrhage. The model including forceps delivery and birth weight was the best predictor for postpartum hemorrhage in Robson Classification 1, 3, 2a, and 4a.

Objective This study aimed to identify the impact of postpartum hemorrhage (PPH) after vaginal delivery on immediate breastfeeding success. Study Design This is a retrospective cohort study examining the impact of PPH on breastfeeding for nulliparous patients after term, singleton, vaginal deliveries at a large academic institution from 2017 to 2018. Indicators of successful breastfeeding in the immediate postpartum period were measured by the presence of breastfeeding, the need for formula supplementation, the average number of breastfeeding sessions per day, the average amount of time spent at each breastfeeding session, the average number of newborn stools and wet diapers produced daily, and the neonatal percentage in weight loss over the first 2 to 3 days of life. Results A total of 1,904 women met inclusion criteria during the study period, 262 (13.8%) of whom experienced PPH, defined as an estimated blood loss of 500 mL or greater after vaginal delivery. Women who had a PPH had significantly fewer breastfeeding sessions on average (β = −0.06, p-value 0.01) and required more time at each breastfeeding session (β = 0.08, p-value <0.002). Neonates of women with PPH had a larger percentage in weight loss over the first 2 to 3 days of life compared with those without PPH (β = 0.06, p = 0.008). Conclusion Women who experience PPH after vaginal delivery have a decreased number of breastfeeding sessions despite spending more time trying to breastfeed, and an increased percentage in neonatal weight loss over the first 2 to 3 days of life. Further work is needed to elicit the mechanism behind this association; however, it is possible that PPH results in decreased secretion of endogenous oxytocin from the hypothalamic–pituitary axis as a result of hypovolemia. These women may therefore require additional breastfeeding support for successful breastfeeding initiation in the immediate postpartum period. Key Points

Objective This retrospective follow-up study analyzes the effect of intrauterine postpartum hemorrhage (PPH) therapy on menstrual, reproductive, and mental health outcomes. Methods All women who delivered at a university hospital between 2016 and 2021 with PPH and who needed intrauterine therapy were included. A questionnaire on well-being, menses, fertility, and reproductive outcomes was mailed to the patients. Those who did not reply were surveyed by telephone. Results A total of 214 women treated with chitosan-covered gauze (group A) and 46 women treated with a balloon tamponade (group B) were recruited, and their short-term courses were analyzed. For long-term follow-up, 71 women of group A (33%) and 21 women of group B (46%) could be reached. A total of 89% of group A and 95% of group B had regular menstrual bleeding in the most recent 12 months; 27% (group A) and 29% (group B) were trying to conceive again, and all of them did so successfully. There were 12 deliveries, 3 ongoing pregnancies, 3 miscarriages, and 2 terminations of pregnancies (TOP) in group A and 4 deliveries, 1 miscarriage, and 2 TOPs in group B. More than half of our study participants was sorted into grade II or III of the Impact of Events Scale, indicating they experienced clinical impacts in the form of psychological sequelae. One-quarter of patients had symptoms of post-traumatic stress disorder. Conclusion Chitosan gauze as well as balloon tamponade appear to have few adverse effects on subsequent menstrual and reproductive function. Women after PPH are at increased risk of long-term adverse psychological outcomes.

Background/Objectives: Transcervical fibroid ablation (TFA) is an incisionless method to treat symptomatic uterine fibroids. While safety regarding future pregnancy remains to be established, TFA does not preclude the possibility of pregnancy, and a previous 36-patient case series of post-TFA pregnancies reported normal outcomes. That prior series did not include postmarket cases in the United States, as the Sonata® System was initially cleared and used in Europe. This is a substantive update of known pregnancies with the Sonata System since June 2011, and includes pregnancies in Europe, Mexico, and the US. Methods: TFA was carried out under both clinical trial and postmarket use to treat symptomatic uterine fibroids. All post-TFA pregnancies reported by physicians with their patient’s consent were included. Results: 89 pregnancies and 55 deliveries have occurred among 72 women treated with the Sonata System. This includes 8 women who conceived more than once after TFA. Completed pregnancies (n = 62 women) include 19 vaginal deliveries, 35 Cesarean sections, 5 therapeutic abortions, 1 ectopic pregnancy, and 1 delivery by an unknown route. Ten pregnancies are ongoing. Mean birthweight was 3276.7 ± 587.3 g. Ten women experienced 18 first-trimester spontaneous abortions (SAbs), with 10 of the 18 SAbs (55.6%) occurring between two patients with a history of recurrent abortion. The SAb rate was 22.8%, inclusive of these two patients, and 10.1% if they were excluded as outliers. There were no instances of uterine rupture, placenta accreta spectrum, or stillbirth. Conclusions: This case series, the largest to date for any hyperthermic ablation modality, suggests that TFA with the Sonata System could be a feasible, safe treatment option regarding eventual pregnancy in women with symptomatic uterine fibroids.

Objective Fetal fibronectin (fFN) testing and transvaginal ultrasound (TVUS) are diagnostic tools used to predict impending spontaneous preterm birth (sPTB) among women presenting with preterm labor (PTL). We evaluated the association between fFN testing or TVUS cervical length (CL) measurement in predicting sPTB, respiratory distress syndrome (RDS), neonatal intensive care unit (NICU) admission, and sPTB-related costs. Study Design We conducted a retrospective cohort study using data from the Kaiser Permanente Southern California electronic health system (January 1, 2009–December 31, 2020) using diagnostic and procedure codes, along with a natural language processing algorithm to identify pregnancies with PTL evaluations. PTL evaluation was defined as having fFN and/or TVUS assessment. Outcomes were ascertained using diagnostic, procedural, and diagnosis-related group codes. Multivariable logistic regression assessed the association between fFN and/or TVUS results and perinatal outcomes. Results Compared with those without PTL evaluations, those with positive fFN tests had higher adjusted odds ratio (adj.OR) for sPTB (2.95, 95% confidence interval [CI]: 2.64, 3.29), RDS (2.34, 95% CI: 2.03, 2.69), and NICU admission (2.24, 95% CI: 2.01, 2.50). In contrast, those who tested negative had lower odds for sPTB (adj.OR: 0.75, 95% CI: 0.70, 0.79), RDS (adj.OR: 0.67, 95% CI: 0.61, 0.73), and NICU admission (adj.OR: 0.74, 95% CI: 0.70, 0.79). Among those with positive fFN results, the odds of sPTB was inversely associated with CL. Health care costs for mothers and neonates were lowest for those with fFN testing only. Conclusion This study demonstrates that positive fFN results were associated with an increased odds of sPTB, RDS, and NICU admission and the association with sPTB was inversely proportional to CL. Additionally, negative fFN results were associated with decreased odds of sPTB, RDS, and NICU admissions. fFN testing may predict these and other sPTB-related adverse outcomes hence its utility should be explored further. Moreover, fFN testing has some cost savings over TVUS. Key Points

Pyroptosis is a type of programmed lytic cell death mechanism associated with the activation of inflammasomes and inflammatory caspases, proteolytic cleavage of gasdermin proteins (GSDMA-E and PJVK), resulting in the formation of pores in cellular membranes such as plasma membrane and mitochondrial membranes. Here, I show that GSDMC expression was increased, GSDME (DFNA5) and PJVK (DFNB59) expression were decreased in uterine corpus endometrial carcinoma (UCEC) cells compared to normal non-malignant endometrial cells. Total percentage of patients affected by mutations in gasdermin family of genes was the highest in UCEC compared to other cancer types. The highest mutation percentage in UCEC patients among the members of the protein family was observed for GSDME which also showed the most significant difference in the mRNA expression among other family members between tumor and normal samples, possibly pointing to its relatively higher importance in the pathogenesis of UCEC. Gasdermin family of genes (except GSDMA) had higher transcript levels in serous endometrial adenocarcinoma than in endometrioid endometrial adenocarcinoma, demonstrating the histotype-dependent expression of the most of gasdermin family of genes in UCEC. Transcript levels of certain gasdermin family members also differed based on residual tumor status and histologic tumor grade; however, the expression of any gasdermin genes did not change depending on menopause status. This study suggests that a better mechanistic understanding of pyroptotic cell death in uterine corpus endometrial carcinoma might help identify novel therapeutic targets for the management of this gynecological malignancy.

Objective Postpartum hemorrhage (PPH) is the leading cause of maternal death globally. Therefore, prevention strategies have been created. The study aimed to evaluate the occurrence of PPH and its risk factors after implementing a risk stratification at admission in a teaching hospital. Methods A retrospective cohort involving a database of SISMATER® electronic medical record. Classification in low, medium, or high risk for PPH was performed through data filled out by the obstetrician-assistant. PPH frequency was calculated, compared among these groups and associated with the risk factors. Results The prevalence of PPH was 6.8%, 131 among 1,936 women. Sixty-eight (51.9%) of them occurred in the high-risk group, 30 (22.9%) in the medium-risk and 33 (25.2%) in the low-risk group. The adjusted-odds ratio (OR) for PPH were analyzed using a confidence interval (95% CI) and was significantly higher in who presented multiple pregnancy (OR 2.88, 95% CI 1.28 to 6.49), active bleeding on admission (OR 6.12, 95% CI 1.20 to 4.65), non-cephalic presentation (OR 2.36, 95% CI 1.20 to 4.65), retained placenta (OR 9.39, 95% CI 2.90 to 30.46) and placental abruption (OR 6.95, 95% CI 2.06 to 23.48). Vaginal delivery figured out as a protective factor (OR 0.58, 95% CI 0.34 to 0.98). Conclusion Prediction of PPH is still a challenge since its unpredictable factor arrangements. The fact that the analysis did not demonstrate a relationship between risk category and frequency of PPH could be attributable to the efficacy of the strategy: Women classified as "high-risk" received adequate medical care, consequently.

Background Placenta accreta spectrum often leads to massive hemorrhage and even maternal shock and death. This study aims to identify whether cervical length and cervical area measured by magnetic resonance imaging correlate with massive hemorrhage in patients with placenta accreta spectrum. Methods The study was conducted at our hospital, and 158 placenta previa patients with placenta accreta spectrum underwent preoperative magnetic resonance imaging examination were included. The cervical length and cervical area were measured and evaluated their ability to identify massive hemorrhage in patients with placenta accreta spectrum. Results The cervical length and area in patients with massive hemorrhage were both significantly smaller than those in patients without massive hemorrhage. The results of multivariate analysis show that cervical length and cervical area were significantly associated with massive hemorrhage. In all patients, a negative linear was found between cervical length and amount of blood loss (r =−0.613), and between cervical area and amount of blood loss (r =−0.629). Combined with cervical length and cervical area, the sensitivity, specificity, and the area under the curve for the predictive massive hemorrhage were 88.618%, 90.209%, and 0.890, respectively. Conclusion The cervical length and area might be used to recognize massive hemorrhage in placenta previa patients with placenta accreta spectrum.

Placenta accreta spectrum disorders (PAS) refers to the penetration of trophoblastic tissue through the decidua basalis into the underlying uterine myometrium, the uterine serosa or beyond, even extending to pelvic organs. It includes both abnormal adherence (placenta accreta) and abnormal invasion (placenta increta and placenta percreta). Cesarean delivery rates, which is the major and most common risk factor, have risen considerably all around the world resulting in increase in incidence of placenta accreta spectrum (PAS) disorders. The importance of the disease is due to the increased maternal and fetal morbidity and mortality associated with it. However, the improvement in prenatal diagnosis and management of these cases in multidisciplinary centres has reduced the mortality rate and is likely to reduce further with increasing experience of clinicians in screening of high-risk patients and development of new surgical techniques. Prenatal diagnosis is one of the most important factors which improves maternal outcome by enabling planned delivery in referral centres with a multidisciplinary care team and adequate resources and equipment. The use of standardized protocol and terminology for both the clinical diagnosis and histopathological confirmation of PAS disorders is essential not only to improve management but also to obtain new and more accurate epidemiological data.

Many areas of medicine would benefit from deeper, more accurate phenotyping, but there are limited approaches for phenotyping using clinical notes without substantial annotated data. Large language models (LLMs) have demonstrated immense potential to adapt to novel tasks with no additional training by specifying task-specific instructions. Here we report the performance of a publicly available LLM, Flan-T5, in phenotyping patients with postpartum hemorrhage (PPH) using discharge notes from electronic health records ( n = 271,081). The language model achieves strong performance in extracting 24 granular concepts associated with PPH. Identifying these granular concepts accurately allows the development of interpretable, complex phenotypes and subtypes. The Flan-T5 model achieves high fidelity in phenotyping PPH (positive predictive value of 0.95), identifying 47% more patients with this complication compared to the current standard of using claims codes. This LLM pipeline can be used reliably for subtyping PPH and outperforms a claims-based approach on the three most common PPH subtypes associated with uterine atony, abnormal placentation, and obstetric trauma. The advantage of this approach to subtyping is its interpretability, as each concept contributing to the subtype determination can be evaluated. Moreover, as definitions may change over time due to new guidelines, using granular concepts to create complex phenotypes enables prompt and efficient updating of the algorithm. Using this language modelling approach enables rapid phenotyping without the need for any manually annotated training data across multiple clinical use cases.

Introduction postpartum hemorrhage is the main cause of maternal death worldwide. Uterine balloon packing has shown promising outcomes in PPH management. Nevertheless, its usage is limited in low- and middle-income countries due to associated costs. Uterine packing using gauzes presents a potentially efficient and cost-effective alternative. This study aims to assess the safety and efficacy of intra-uterine packing with gauzes in managing postpartum hemorrhage. Methods this was a retrospective study over a period of two years and six months. All patients who experienced PPH due to uterine atony during vaginal delivery, with no response to medical first-line treatment, were included. IUP using gauze was employed as a second-line intervention. The primary outcome was the success of postpartum hemorrhage management. Secondary outcomes included patient vitals, the need for blood transfusion, change in hemoglobin levels (delta Hemoglobin), and maternal morbidity (post-partum infection, Sheehan syndrome, and retained gauzes). Results the study included 63 patients. The mean age was 30.06 ± 5.6, the mean gravida was 2.65 ± 1.9 and the mean para was 2.12 ± 1.31. None of these patients experienced major complications following gauze insertion. Three patients underwent laparotomy and conservative surgical management was performed. Hysterectomy was not required for any participant, and no maternal deaths were recorded.

Objectives This study aimed to clarify the relationship between white blood cell (WBC) and adverse pregnancy outcomes. Design A total of 25 270 pregnant women underwent peripheral blood white blood cell count tests in the first, second and third trimesters. Adverse pregnancy outcomes were gestational hypertension, pre-eclampsia, gestational diabetes mellitus, preterm birth, low birth weight, caesarean delivery, macrosomia and fetal distress. Due to acute infectious disease or other diseases, 1127 were excluded. Setting Minhang Hospital, China. Participants A total of 24 143 pregnant women were included in this study. Primary and secondary outcome measures The primary outcome was the adverse pregnancy outcomes. Results For the 24 143 participants, we calculated adjusted ORs for adverse pregnancy outcomes associated with an increased WBC count. For gestational hypertension, the ORs were 1.18 (95% CI, 1.05 to 1.24) in the first trimester and 1.10 (1.06 to 1.13) in the second trimester; for pre-eclampsia, ORs were 1.14 (95% CI, 1.47 to 1.64) in the first trimester and 1.10 (1.05 to 1.16) in the second trimester; for gestational diabetes mellitus, ORs were 1.06 (95% CI, 1.00 to 1.13) in the first trimester and 1.10 (1.04 to 1.16) in the second trimester; for preterm birth, ORs were 1.12 (95% CI, 1.06 to 1.18) in the first trimester, 1.10 (1.06 to 1.13) in the second trimester and 1.12 (1.09 to 1.15) in the third trimester; for low birth weight, ORs were 1.09 (95% CI, 1.02 to 1.17) in the first trimester, 1.03 (0.99 to 1.08) in the second trimester and 1.12 (1.08 to 1.16) in the third trimester. Significant associations were not observed obviously for caesarean delivery, macrosomia and fetal distress. Conclusions Our results indicate strong, continuous associations of maternal WBC count with increased risks of adverse pregnancy outcomes.

Background Uterine compression methods reduce the amount of postpartum bleeding. In our study, we investigated the effect of fundal pressure, which will be created by a sandbag placed on the abdomen, on reducing post-cesarean bleeding. Methods A total of 482 patients who delivered by cesarean section (CS) in the Obstetrics Clinic of Fırat University Faculty of Medicine between January 2021 and December 2021 were included in this prospective, randomized, single-center study. There were two groups: control group (n = 246), weighted group (n = 236). A sandbag weighing approximately 3 kg was used as a fundal compression tool. Hemoglobin (Hb) and hematocrit (Hct) concentrations and amount of vaginal bleeding were determined preoperatively and at the postoperative 8th and 24th hours. In addition, the time of milk coming from the breast and visual analogue scale (VAS) were evaluated. Results The postoperative Hb value at 24 hours was significantly lower in weighted group compared to control group. The estimated amount of postoperative bleeding (based on the number of pads) was higher in weighted group compared to control group. The time to onset of milk production from the breast at the postoperative 8th hour was significantly longer in weighted group compared to control group. Postoperative VAS scores at 24 hours were significantly higher in weighted group compared to control group. Conclusions Applying fundal pressure by using a sandbag from the abdominal route seems ineffective in reducing the amount of bleeding after CS. It may even increase the amount of bleeding. Clinical Trial Registration The study was registered athttps://clinicaltrials.gov/, registration number: NCT06005831.

Objectives The aim of this study was to investigate the short-term outcomes of knotless barbed sutures used for both closures of myometrium and subcuticular tissues in patients with various operative indications and who underwent cesarean delivery (CD) in a single tertiary center. Materials and methods A retrospective cohort study was conducted, and the patients were divided into two groups. The barbed suture group consisted of patients who underwent CD using barbed sutures for uterine closure (0 Stratafix® Spiral PDS Plus, Ethicon, Somerville, NJ, USA) and subcuticular closure (4-0 Stratafix® Spiral PDS Plus). The non-barbed group consisted of patients who underwent CD using monofilament sutures for uterine closure (0-Monocryl®, Ethicon) and subcuticular closure (3-0 Opepolyx®, Alfresa, Tokyo, Japan). Results White blood cell count on post-operative day 1 was statistically lower in the barbed suture group (p=0.01), while there were no other significant differences between the two groups. Conclusion Barbed sutures can be used without major complications in patients who have undergone CD, including high-risk pregnancies.

Background and Objectives: The aim of this study was to assess the differences in Doppler indices of the uterine (Ut), umbilical (UA), and middle cerebral artery (MCA) in diabetic versus non-diabetic pregnancies by conducting a comprehensive systematic review of the literature with a meta-analysis. Materials and Methods: PubMed, Web of Science, and SCOPUS were searched for studies that measured the pulsatility index (PI), resistance index (RI), and systolic/diastolic ratio index (S/D ratio) of the umbilical artery, middle cerebral artery, and uterine artery in diabetic versus non-diabetic pregnancies. Two reviewers independently evaluated the eligibility of studies, abstracted data, and performed quality assessments according to standardized protocols. The standardized mean difference (SMD) was used as a measure of effect size. Heterogeneity was assessed using the I2 statistic. Publication bias was evaluated by means of funnel plots. Results: A total of 62 publications were included in the qualitative and 43 in quantitative analysis. The UA-RI, UtA-PI, and UtA-S/D ratios were increased in diabetic compared with non-diabetic pregnancies. Subgroup analysis showed that levels of UtA-PI were significantly higher during the third, but not during the first trimester of pregnancy in diabetic versus non-diabetic pregnancies. No differences were found for the UA-PI, UA-S/D ratio, MCA-PI, MCA-RI, MCA-S/D ratio, or UtA-RI between diabetic and non-diabetic pregnancies. Conclusions: This meta-analysis revealed the presence of hemodynamic changes in uterine and umbilical arteries, but not in the middle cerebral artery in pregnancies complicated by diabetes.

Rationale: Placental residue is a relatively common and sophisticated disease among obstetric delivery complications. A failure to detect placental residue in time may cause poor outcomes such as postpartum hemorrhage and puerperal infection. Patient concerns: We present the case of a 33-year-old full-term singleton parturient with placental residue. Upon precipitate labor and childbirth, the placenta and fetal membranes were examined to be intact. However, 1 day after discharge, she felt that there was discharge from the vagina and thus presented to our emergency department. Diagnoses: The patient was diagnosed with residual membranes and readmitted to the hospital for uterine curettage. Intervention: Uterine curettage was performed under B-ultrasound guidance. Outcome: The patient was discharged smoothly without any postoperative complications. Lessons: This paper can provide significant enlightenment for the prevention and early treatment of placental residue, including enhancing the risk awareness of high-risk patients, standardizing the process of clinical examination of the placenta, and early uterine contraction promotion to assist in the discharge of residual tissue, so as to reduce the occurrence of placental residue.

Background When determining adjuvant treatment for endometrial cancer, the decision typically relies on factors such as cancer stage, histologic grade, subtype, and a few histopathologic markers. The Cancer Genome Atlas revealed molecular subtyping of endometrial cancer, which can provide more accurate prognostic information and guide personalized treatment plans. Objective To summarize the expression and molecular basis of the main biomarkers of endometrial cancer. Search Strategy PubMed was searched from January 2000 to March 2023. Selection Criteria Studies evaluating molecular subtypes of endometrial cancer and implications for adjuvant treatment strategies. Data Collection and Analysis Three authors independently performed a comprehensive literature search, collected and extracted data, and assessed the methodological quality of the included studies. Main Results We summarized the molecular subtyping of endometrial cancer, including mismatch repair deficient, high microsatellite instability, polymerase epsilon (POLE) exonuclease domain mutated, TP53 gene mutation, and non‐specific molecular spectrum. We also summarized planned and ongoing clinical trials and common therapy methods in endometrial cancer. POLE mutated endometrial cancer consistently exhibits favorable patient outcomes, regardless of adjuvant therapy. Genomic similarities between p53 abnormality endometrial cancer and high‐grade serous ovarian cancer suggested possible overlapping treatment strategies. High levels of immune checkpoint molecules, such as programmed cell death 1 and programmed cell death 1 ligand 1 can counterbalance mismatch repair deficient endometrial cancer immune phenotype. Hormonal treatment is an appealing option for high‐risk non‐specific molecular spectrum endometrial cancers, which are typically endometrioid and hormone receptor positive. Combining clinical and pathologic characteristics to guide treatment decisions for patients, including concurrent radiochemotherapy, chemotherapy, inhibitor therapy, endocrine therapy, and immunotherapy, might improve the management of endometrial cancer and provide more effective treatment options for patients. Conclusions We have characterized the molecular subtypes of endometrial cancer and discuss their value in terms of a patient‐tailored therapy in order to prevent significant under‐ or overtreatment.

Background: Uterine atony is the most common cause of postpartum hemorrhage, which is the leading preventable cause of maternal morbidity and mortality. Despite several interventions uterine atony-related postpartum hemorrhage remains a global challenge. Identifying risk factors of uterine atony helps to reduce the risk of postpartum hemorrhage and subsequent maternal death. However, evidence about risk factors of uterine atony is limited in the study areas to suggest interventions. This study aimed to assess determinants of postpartum uterine atony in urban South Ethiopia. Methods: A community-based unmatched nested case-control study was conducted from a cohort of 2548 pregnant women who were followed-up until delivery. All women with postpartum uterine atony (n = 93) were taken as cases. Women who were randomly selected from those without postpartum uterine atony (n = 372) were taken as controls. Using a case to control ratio of 1:4, the total sample size was 465. An unconditional logistic regression analysis was done using R version 4.2.2 software. In the binary unconditional logistic regression model variables that have shown association at p < 0.20 were recruited for multivariable model adjustment. In the multivariable unconditional logistic regression model, statistically significant association was declared using 95% CI and p < 0.05. Adjusted odds ratio (AOR) used to measure the strength of association. Attributable fraction (AF) and population attributable fraction (PAF) were used to interpret the public health impacts of the determinants of uterine atony. Results: In this study, short inter-pregnancy interval < 24 months (AOR = 2.13, 95% CI: 1.26, 3.61), prolonged labor (AOR = 2.35, 95% CI: 1.15, 4.83), and multiple birth (AOR = 3.46, 95% CI: 1.25, 9.56) were determinants of postpartum uterine atony. The findings suggest that 38%, 14%, and 6% of uterine atony in the study population was attributed to short inter-pregnancy interval, prolonged labor, and multiple birth, respectively, which could be prevented if those factors did not exist in the study population. Conclusions: Postpartum uterine atony was related to mostly modifiable conditions that could be improved by increasing the utilization of maternal health services such as modern contraceptive methods, antenatal care and skilled birth attendance in the community.

The study intends to repurpose FDA drugs and investigate the mechanism of (5HT2BR) activation by comprehending inter-residue interactions. The 5HT2BR is a novel thread, and its role in reducing seizures in Dravet syndrome is emerging. The crystal structure (5HT2BR) is a chimera with mutations; hence 3D-structure is modeled (4IB4: 5HT2BRM). The structure is cross-validated to simulate the human receptor using enrichment analysis (ROC: 0.79) and SAVESv6.0. Virtual screening of 2456 approved drugs yielded the best hits that are subjected to MM/GBSA and molecular dynamic (MD) simulations. The 2 top drugs Cabergoline (-53.44 kcal/mol) and Methylergonovine (-40.42 kcal/mol), display strong binding affinity, and ADMET/SAR analysis also suggests their non-mutagenic or non-carcinogenic nature. Methylergonovine has a weaker binding affinity and lower potency than standards [Ergotamine (agonist) and Methysergide (antagonist)] due to its higher Ki (1.32 M) and Kd (6.44 ×10-8 M) values. Compared to standards, Cabergoline has moderate binding affinity and potency [Ki = 0.85 M and Kd = 5.53 × 10-8 M]. The top 2 drugs primarily interact with conserved residues (ASP135, LEU209, GLY221, ALA225, and THR140) as in agonists, unlike the antagonist. The top 2 drugs, upon binding to the 5HT2BRM, modify the helices VI, V, and III and shift the RMSD 2.48 Å and 3.07 Å. LEU209 forms a latch with residues 207-214 (forms a lid) in the 5HT2BRM receptor, which enhances agonist binding and prevents drug escape. Methylergonovine and Cabergoline interact more stongly with ALA225 than the antagonist. The post-MD analysis of Cabergoline suggests a better MM/GBSA value (-89.21 kcal/mol) than Methylergonovine (-63.54 kcal/mol). In this study, Cabergoline and Methylergonovine's agonistic mechanism and solid binding properties suggest their strong role in regulating the 5HT2BR and might target drug-resistant epilepsy.

Background Epidural analgesia (EA) increases the risks of maternal fever during labor, which is associated with adverse maternal and neonatal outcomes, while the risk factors for epidural-associated fever and strategies for minimizing these effects remain limited. Methods A total of 325 pregnant women were retrospectively analyzed who had attended our hospital for a vaginal in-hospital delivery, including 208 who voluntarily accepted EA and 117 who did not receive EA. During labor, 208 EA women were allocated to a fever group (n = 42, a tympanic temperature ≥37.5 °C during labor), and a no fever group (n = 166). The outcome measures included main maternal and neonatal outcomes, labor times, duration of EA and the total EA dosage administered. Results 42 out of 208 women given EA exhibited fever temperatures during labor, which were higher than in women who did not receive EA (20.19% vs. 0.85%). Maternal fever had an increased risks for conversion to surgery (adjusted odds ratio (AOR), 4.05; 95% CI, 1.44–11.39) and neonatal infections (5.13; 1.98–13.29) compared to the no fever group. While maternal fever did not increase the risks for assisted vaginal delivery, fetal distress or admission to the neonatal intensive care unit (NICU), it was predominantly associated with primiparity and lesser times of gravity. Frequent cervical examinations, the duration of first stage and total labor, and the duration of EA and its total dosage were positively correlated with the incidence of fever. Furthermore, after stratifying risk factors into subgroups, we found that more frequent cervical examinations (≥7 times) and longer duration of first stage (≥442.5 min), total labor time (≥490 min), EA (≥610.0 min) increased the risk for epidural-associated fever after adjustment for potential confounding factors. Conclusions EA increased the risk of intrapartum epidural-associated fever, which was correlated with adverse perinatal outcomes. Nulliparity, less times of gravidity, ≥7 cervical examinations, increased volume of the EA dosage, prolonged duration of EA and total labor time were risk factors for epidural-associated fever. The findings provide clinicians with insights and strategies to prevent epidural-associated fever more safely and effectively.

Endometrial cancer is the most common type of gynaecological cancer in high-income countries. Abnormal uterine bleeding (AUB) is the most common symptom of endometrial cancer; however, patients can often present in an atypical fashion. This case is an example of an atypical presentation of endometrial cancer, with angina secondary to severe iron deficiency anemia, and a rare example of pancytopenia secondary to iron deficiency. A 46-year-old nulliparous woman with no past medical history presented to the emergency department with acute chest pain. All her vitals were normal. The ECG showed T-wave inversion with a negative serum troponin. She had obvious pallor but appeared well. She had a critical hemoglobin of 1.9 g/dL and severe iron deficiency with a plasma iron level of <2 μg/L. In the 6 months leading up to her presentation, she had heavy and prolonged menstruation of up to 10 days. She received a total of 6 units of packed red blood cells and an iron infusion. Her chest pain resolved, and her pancytopenia corrected following replenishment of iron stores. She underwent a laparoscopic total hysterectomy, bilateral salpingo-oophorectomy for stage 1b, grade 2 endometroid adenocarcinoma. This is one of the lowest hemoglobin levels recorded in a hemodynamically stable patient with endometrial cancer, and the only case report of iron deficiency induced pancytopenia secondary to abnormal uterine bleeding. This case is a reminder that female patients with angina should have their hemoglobin checked, and patients with anemia should have a thorough review of their gynaecological history.

Background: The reported success rate of uterine artery embolization (UAE) for postpartum hemorrhage (PPH) differs by the cause of bleeding; in some reports, UAE shows less successful results in patients with placenta accreta spectrum (PAS). Purpose: To evaluate the outcome of UAE for treating PPH associated with PAS. Material and methods: From September 2011 to September 2021, 227 patients (mean age = 34.67±4.06 years; age range = 19-47 years) underwent UAE for managing intractable PPH. Patients were divided into two groups: those with PAS (n = 46) and those without PAS (n = 181). Delivery details, embolization details, and procedure-related outcomes were compared between the two groups. P values <0.05 were considered statistically significant. Results: The technical success rate was 96.9% (n = 222) and the clinical success rate was 93.8% (n = 215). There were no significant differences in outcome of UAE between the two patient groups. The technical success rate was 95.7% (n = 44) in patients with PAS and 98.3% (n = 178) in patients without PAS (P = 0.267). The clinical success rate was 91.3% (n = 42) in patients with PAS and 95.6% (n = 173) in patients without PAS (P = 0.269). There were 24 cases of immediate complications, including pelvic pain (n = 20), urticaria (n = 3), and puncture site hematoma (n = 1). No major complication was reported. Conclusion: UAE is a safe and effective method to control intractable PPH for patients with or without PAS.

Postpartum hemorrhage (PPH) is one of the main causes of severe maternal mortality and morbidity.Multiple factors can induce this massive hemorrhage and the rule of the “4 Ts” best summarize them: tone (loss of uterine tone), tissue (retention of placental tissue), trauma, and thrombin (coagulopathies). Prenatal risk factors for PPH are nowadays well known but unpredictable events are part of the daily practice.Therapeutic measures should be applied for blood loss greater than 500 and 1000 mL after vaginal and cesarean deliveries, respectively; all measures aim to obtain hemodynamic control of the patient and to identify and treat the cause of hemorrhage.PPH management includes a multidisciplinary evaluation characterized by the application of subsequent progressive steps: medical and support care, non-invasive conservative maneuvers, conservative surgery, and hysterectomy. In this scenario, endovascular embolization presents an effective role when conservative methods fail and allow to avoid hysterectomies.In this chapter, PPH rescue management will be discussed, focusing in detail on the role of embolization with its technical analysis.KeywordsEmbolizationPPHUterine arteriesPelvisRescue

Objective To evaluate the efficacy of Chinese plaster containing rhubarb and mirabilite on surgical site infection (SSI) in patients with cesarean delivery (CD) by performing a randomized controlled trial.Methods This randomized controlled trial included 560 patients with CD due to fetal head descent enrolled at a tertiary teaching center between December 31, 2018 and October 31, 2021. Eligible patients were randomly assigned to a Chinese medicine (CM) group (280 cases) or a placebo group (280 cases) by a random number table, and were treated with CM plaster (made by rhubarb and mirabilite) or a placebo plaster, respectively. Both courses of treatment lasted from the day 1 of CD, followed day 2 until discharge. The primary outcome was the total number of patients with superficial, deep and organ/space SSI. The secondary outcome was duration of postoperative hospital stay, antibiotic intake, and unplanned readmission or reoperation due to SSI. All reported efficacy and safety outcomes were confirmed by a central adjudication committee that was unaware of the study-group assignments.ResultsDuring the recovery process after CD, the rates of localized swelling, redness and heat were significantly lower in the CM group than in the placebo group [7.55% (20/265) vs. 17.21% (47/274), P<0.01]. The durution of postoperative antibiotic intake was shorter in the CM group than in the placebo group (P<0.01). The duration of postoperative hospital stay was significantly shorter in the CM group than in the placebo group (5.49 ± 2.68 days vs. 8.96 ± 2.35 days, P<0.01). The rate of postoperative C-reactive protein elevation (≽100 mg/L) was lower in the CM group than in the placebo group [27.6% (73/265) vs. 43.8% (120/274), P<0.01]. However, there was no difference in purulent drainage rate from incision and superficial opening of incision between the two groups. No intestinal reactions and skin allergies were found in the CM group.ConclusionsCM plaster containing rhubarb and mirabilite had an effect on SSI. It is safe for mothers and imposes lower economic and mental burdens on patients undergoing CD. (Registration No. ChiCTR2100054626)

Background: The objective of this study was to evaluate the efficacy of intraoperative aortic balloon occlusion (IABO) during caesarean section for placenta accreta, increta or percreta and explore the relationship between different profile balloon catheters and catheter-related complications. Methods: This retrospective case control study included 295 patients with pathologically confirmed placenta accreta spectrum (PAS) disorder at the Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital between 2013 and 2019. The characteristics of 162 patients who had aortic balloon occlusion (balloon group) were compared with those of 133 patients who had no catheterization (control group). Results: There were significant differences between the two groups in estimated blood loss, calculated blood loss, number of transfusions, transfused packed red blood cells (PRBCs), haemoglobin reduction, operation time and caesarean hysterectomy (P < 0.05). Regarding different PAS disorders, the estimated blood loss among women with placenta accreta and placenta increta was lower in the balloon group (n = 32 and 102, respectively) than in the non-balloon group (n = 33 and 85; P = 0.04 and P < 0.01, respectively). Only the placenta increta group showed a significant difference (P < 0.01) in transfused PRBCs. In patients who used the low-profile balloon catheters, we found a significant reduction in catheter-related complications compared with the high-profile group (n = 52 vs. 110, P = 0.04). Conclusions: Our study demonstrated that intraoperative infrarenal aortic balloon occlusion was effective in both reducing intraoperative haemorrhage and blood transfusion, and in preventing hysterectomy during caesarean section for pathologically diagnosed placenta accreta and increta. Low-profile balloon catheters can reduce catheter-related complications.

Blood transfusion is defined as the delivery of blood components and coagulation factor concentrates to a patient. About half of transfusions between the ages of 20 and 35 are performed in obstetrics and gynecology clinics. Electronic file records of 137 patients who underwent blood transfusion in Muğla Training and Research Hospital, Gynecology and Obstetrics Clinic between January 2014 and December 2018 were reviewed retrospectively. The demographic information of the patients, Hemoglobin and Hematocrit (before and after transfusion) values, and applied blood products and their amount were recorded. Of the patients who received blood transfusion, 79 were obstetric and 58 were gynecological patients. In obstetric cases, blood transfusion was most frequently performed after cesarean section (56.6%). Among the causes of transfusion, 43 (54%) patients had anemia after anemia, 10 (12.6%) patients had anemia after D/C, and 5 (6.32%) patients had uterine atony. Diagnostic dilatation/curettage (D/C) and total abdominal hysterectomy were performed in 12 (20.68%) of 58 patients, who were transfused for gynecological reasons, with the diagnosis of menometrorrhagia, while myomectomy was performed in 10 of these patients (17.24%), total laparoscopic hysterectomy was performed in 9 (15.51%) patients, urogynecological surgery and laparoscopic cystectomy were performed in 5 (8.62%) patients, and medical treatment was given with the diagnosis of menometrorrhagia. The preparation and use of blood and blood products should be approached in a multidisciplinary manner, covering many branches, especially Gynecology and Obstetrics and Hematology. Anemia prophylaxis should be initiated beforehand and post-operative transfusion should be reduced in pregnant women and patients who will undergo surgery. Unnecessary transfusions should be avoided in order to avoid complications that may occur during and after transfusion.

Despite improvements in healthcare technologies, massive postpartum haemorrhage is still the leading cause of maternal morbidity and mortality worldwide. Delayed and poor-quality obstetric care can result in irreversible consequences. Well-timed assessment of blood loss, effective management of the peripartum period, and participation of multidisciplinary teams are essential to provide a specialized care. This review presents the evidence-based management of patients with the development of obstetric haemorrhage. The article presents existing contradictions in the methods of diagnosis and treatment as well as new advances in this field of medicine which require continuation of research in this direction.

Objective To evaluate a novel curriculum to enhance knowledge and preparedness of emergency medicine (EM) residents in the management of postpartum hemorrhage (PPH). Methods A randomized controlled trial examining two pedagogical approaches. Following baseline testing of knowledge and confidence in respect of PPH management, participants were randomized to receive a didactic lecture on PPH management (group A, n = 14) or a didactic lecture followed by simulation‐based training on PPH management and debriefing (group B, n = 16). Post‐intervention, proficiency in PPH management was evaluated by clinical skills simulation and post‐intervention assessment for participants. The change in the mean test and clinical skills scores were compared using Student's t‐test. Linear regression examined the effects of covariates. Results Both forms of intervention increased participants' knowledge of (group A: mean = 2.50, 95% confidence interval [CI] 1.63–3.37, P < 0.001; group B: mean = 1.56, 95% CI 0.89–2.24, P < 0.001) and confidence in PPH management (group A: mean = 1.00, 95% CI 0.46–1.54, P = 0.003; group B: mean = 1.00, 95% CI 0.52–1.48, P = 0.001), relative to baseline. However, addition of simulation and debriefing to the didactic session did not offer any advantage (knowledge: mean = −0.94, 95% CI –1.97 to 0.10, P = 0.074; confidence: mean = 0.00, 95% CI –0.66 to 0.66, P = 1.000). Conclusion Delivery of a structured curriculum led to improvement of knowledge and confidence with regard to the management of PPH by EM residents.

Purpose Endometrial cancer in recent years has taken the lead among cancer processes of the female reproductive system. The feasibility of pelvic and para-aortic lymph node dissection in patients with endometrial cancer has always been a controversial issue. The aim of the presented paper is to evaluate the feasibility of pelvic and para-aortic lymph node dissection in patients with endometrial cancer, depending on the stage of the disease, postoperative complications, and patient survival, depending on the volume of surgical intervention. Methods The study involved 285 patients with stages of I–IV endometrioid endometrial cancer of the Pre-graduate Department of Oncogynecology of the National Cancer Institute. The average age of patients was 55 ± 5.7 years. In 74.5%, the disease was detected at stage I and uterine extirpation was performed with/without appendages. Results The duration of the operation varies depending on the volume of intervention—from 1 h 30 min ± 10 min for panhysterectomy, up to 3 h 20 min ± 10 min when performing para-aortic lymph node dissection. The average number of lymph nodes removed was—7 ± 1.1 pelvic and 12 ± 1.5 para-aortic. Conclusion The basic principles of surgical treatment consist in individual choice of the scope of surgical intervention, performing adequate lymph node dissection, and preventing relapse and metastasis of the disease.
Abstract Purpose: To determine whether preeclampsia and gestational diabetes mellitus is a risk factor for cochlear damage and sensorineural hearing impairment in infants. Materials and Methods: Longitudinal study was conducted in 2 tertiary referral centers. 1068 neonates were included, who were born to preeclampsia, gestational diabetes mellitus, and healthy mothers. The hearing evaluation was done using DPOAE on day 2 and for those who failed the initial DPOAE on day 2, underwent repeat DPOAE on day 15, ABR was done on day 30 if repeat DPOAE was Refer. The results were compared between the groups and analyzed. Results: On initial DPOAE, bilateral ear absent DPOAE rates were 19.5%, 15.8%, and 3.5% among preeclampsia, Gestational Diabetes Mellitus (GDM), control groups respectively. The difference was statistically significant (P<.001). Also it was noted that absent DPOAE was significantly high at low and mid frequencies (1000, 2000, 3000, and 4000Hz) in bilateral ear. However the difference in repeat DPOAE among the groups were not significant (Right ear P=.17, Left ear P=.31). Infants who failed repeat DPOAE test underwent ABR test in which 3 of GDM group, 2 infants of preeclampsia group and 1 infant of control group had absent ABR test. Conclusion: This study reveals that GDM and preeclampsia showed remarkable association of hearing loss at lower and mid frequencies which was transient. The prevalence of absent DPOAE was corresponding to the severity of the maternal conditions under the study
