During pregnancy, fetal growth could lead to changes in human biomechanics. If postpartum recovery was not properly managed, it could be exacerbated, resulting in myofascial system disorders and various functional impairments. Among them, pain-related functional disorders were an important issue affecting quality of life in postpartum women. The pathogenesis of these disorders remained unclear but it was primarily associated with changes in biomechanics, the endocrine system, and nervous function. However, postpartum pain-related dysfunction had been considered a normal physiological response to childbirth, leading to a lack of attention. Therefore, many postpartum women failed to receive timely, effective, and standardized treatment, hindering their ability to reintegrate into family and society, and causing severe damage to their physical and mental health. In clinical practice, myofascial therapy could effectively alleviate postpartum pain and muscle spasms, improve excessive tension injuries in myofascial, and had a good therapeutic effect on postpartum pain-related functional disorders. The mechanism of myofascial therapy involved improving core muscle strength, restoring normal body alignment, and promoting the remodeling of myofascial mechanical structures. This article explored the positive effects of myofascial therapy on postpartum pain-related functional disorders from a biomechanical perspective, aiming to provide diverse treatment approaches for clinical practitioners., (Copyright © 2024 the Author(s).

Postpartum post-traumatic stress disorder (PP-PTSD) is a severe mental disorder worldwide. In recent years, some studies have reported that PP-PTSD stems from birth trauma. The present study was dedicated in finding ways to predict the occurrence of emergency caesarean section (ECS), trying to analyze the methods to reduce incidence of PP-PTSD on this basis, further exploring the neuroimaging changes in PP-PTSD. A total of 245 primiparas with intention of vaginal delivery were recruited. The internal tocodynamometry measurement was performed during labor for all mothers, and respectively taken at 3-5 cm, 5-8 cm, and 8-10 cm of cervical dilation. The receiver operating characteristic (ROC) curve and Binary logistic regression analyses were also performed to identify fetal head descending thrust that might help in the prediction of ECS. Resting-state magnetic resonance imaging (MRI) was performed on 26 patients diagnosed with PP-PTSD of 245 mothers, the amplitude of low-frequency fluctuations (ALFF) technology was used to observe the spontaneous neural activity of all PP-PTSD patients and correlation analyses were performed. We found that the natural delivery rate of mothers with fetal head descending thrust <16.29 N (5-8 cm), 26.36 N (8-10 cm) were respectively lower than other mothers with fetal head descending thrust ≥16.29 N (5-8 cm), 26.36 N (8-10 cm) (P < 0.05). The ROC curve analysis showed that the area under the receiver operating characteristic curve (AUC) value of thrust (5-8 cm) was 0.896 (95% CI: 0.854-0.938, p < 0.001), AUC of thrust(8-10 cm) was 0.786 (95% CI: 0.714-0.858, p < 0.001), which showed strong potential for predicting ECS. In addition, the Binary logistic regression analysis showed thrust (5-8 cm) and thrust (8-10 cm) were independent correlates of ECS. The resting-state functional magnetic resonance imaging (rs-fMRI) results indicated that PP-PTSD group showed decreased ALFF in the bilateral insula cortex (IC), right anterior cingulate cortex (ACC), and left midcingulate cortex (MCC) compared with healthy postpartum women (HPW) (false discovery rate (FDR) correction q-value < 0.05). The ALFF value of the right ACC was positively correlated with the Perinatal Post-traumatic stress disorder Questionnaire (PPQ) score (r = 0.4046 p = 0.0403) and Posttraumatic Stress Disorder Checklist-Civilian Version (PCL-C) score (r = 0.3909 p = 0.0483). The internal tocodynamometry measurement can serve as a predictive tool for ECS, on this basis, the implementation of effective emotional support may help to reduce the incidence of PP-PTSD. Besides, this study has verified the presence of altered ALFF in the brain regions of PP-PTSD patients, mainly involving the bilateral IC, right ACC, and left MCC, that might be associated with emotion, cognition, and memory disorders functions in PP-PTSD patients., (© 2024.

Background: Although peripartum cardiomyopathy (PPCM) is a fatal disease affecting young patients and fetuses, little is known about its recent prognosis and risk factors. This study investigated temporal trends in clinical characteristics and outcomes for PPCM in a nationwide multicenter registry., Methods and Results: The study population comprised 340 patients (mean age, 33 years) who were diagnosed with PPCM between January 2000 and September 2022 in 26 tertiary hospitals in South Korea. PPCM was defined as heart failure with left ventricular ejection fraction ≤45% and no previously known cardiac disease. The main study outcomes included time to the first occurrence of all-cause death, heart transplantation, and cardiovascular hospitalization. The diagnosis of PPCM cases increased notably during the study period ( P <0.001). However, clinical outcomes showed no significant improvement (all-cause death for 10 years: 0.9% [2000-2010] versus 2.3% [2011-2022], P =0.450; all-cause death and heart transplantation for 10 years: 3.6% [2000-2010] versus 3.0% [2011-2022] P =0.520; all-cause death, heart transplantation, and cardiovascular hospitalization for 10 years: 11.7% [2000-2010] versus 19.8% [2011-2022], P =0.240). High body mass index (hazard ratio [HR], 1.106 [95% CI, 1.024-1.196]; P =0.011), the presence of gestational diabetes (HR, 5.346 [95% CI, 1.778-16.07]; P =0.002), and increased baseline left ventricular end-diastolic dimension (HR, 1.078 [95% CI, 1.002-1.159]; P =0.044) were significant risk factors for poor prognosis., Conclusions: While the incidence of PPCM has increased over the past 20 years, the prognosis has not improved significantly. Timely management and close follow-up are necessary for high-risk patients with PPCM with high body mass index, gestational diabetes, or large left ventricular end-diastolic dimension.

Background: Hypertensive disorders of pregnancy are one of the leading causes of maternal morbidity and mortality worldwide. Management of these conditions can pose many clinical dilemmas and can be particularly challenging during the immediate postpartum period. Models for predicting and managing postpartum hypertension are necessary to help address this clinical challenge., Objective: This study aimed to evaluate predictive models of blood pressure spikes in the postpartum period and to investigate clinical management strategies to optimize care., Study Design: This was a retrospective cohort study of postpartum women who participated in remote blood pressure monitoring. A postpartum blood pressure spike was defined as a blood pressure measurement of ≥140/90 mm Hg while on an antihypertensive medication and a blood pressure measurement of ≥150/100 mm Hg if not on an antihypertensive medication. We identified 3 risk level patient clusters (low, medium, and high) when predicting patient risk for a blood pressure spike on postpartum days 3 to 7. The variables used in defining these clusters were peak systolic blood pressure before discharge, body mass index, patient systolic blood pressure per trimester, heart rate, gestational age, maternal age, chronic hypertension, and gestational hypertension. For each risk cluster, we focused on 2 treatments, namely (1) postpartum length of stay (<3 days or ≥3 days) and (2) discharge with or without blood pressure medications. We evaluated the effectiveness of the treatments in different subgroups of patients by estimating the conditional average treatment effect values in each cluster using a causal forest. Moreover, for all patients, we considered discharge with medication policies depending on different discharge blood pressure thresholds. We used a doubly robust policy evaluation method to compare the effectiveness of the policies., Results: A total of 413 patients were included, and among those, 267 (64.6%) had a postpartum blood pressure spike. The treatments for patients at medium and high risk were considered beneficial. The 95% confidence intervals for constant marginal average treatment effect for antihypertensive use at discharge were -3.482 to 4.840 and - 5.539 to 4.315, respectively; and for a longer stay they were -5.544 to 3.866 and -7.200 to 4.302, respectively. For patients at low risk, the treatments were not critical in preventing a blood pressure spike with 95% confidence intervals for constant marginal average treatment effect of 1.074 to 15.784 and -2.913 to 9.021 for the different treatments. We considered the option to discharge patients with antihypertensive use at different blood pressure thresholds, namely (1) ≥130 mm Hg and/or ≥80 mm Hg, (2) ≥140 mm Hg and/or ≥90 mm Hg, (3) ≥150 mm Hg and/or ≥ 100 mm Hg, or (4) ≥160 mm Hg and/or ≥ 110 mm Hg. We found that policy (2) was the best option with P<.05., Conclusion: We identified 3 possible strategies to prevent outpatient blood pressure spikes during the postpartum period, namely (1) medium- and high-risk patients should be considered for a longer postpartum hospital stay or should participate in daily home monitoring, (2) medium- and high-risk patients should be prescribed antihypertensives at discharge, and (3) antihypertensive treatment should be prescribed if patients are discharged with a blood pressure of ≥140/90 mm Hg., (Copyright © 2024.

Background: Postpartum hypertension is a major contributor to the rising maternal mortality rates in the United States, with nearly half of maternal deaths occurring after delivery. Previous studies have found evidence that the maximum blood pressure reading during labor and delivery admission can predict readmission; however, the optimal blood pressure to reduce the need for readmissions and additional medical treatment in the postpartum period is not known., Objective: This study aimed to investigate the relationship between postpartum blood pressure control at discharge and readmission within the first 6 weeks after delivery., Study Design: Data were obtained from Cosmos, an electronic health record-based, Health Insurance Portability and Accountability Act-defined limited dataset that includes more than 1.4 million birth encounters. All birthing parents with blood pressure data after delivery were included. Demographic information, medications, and readmissions were queried from the dataset. Patients were grouped into categories based on blood pressure readings in the 24 hours before discharge (≥160/110, ≥150/100, ≥140/90, ≥130/80, ≥120/80, and <120/80 mm Hg). The readmission rates across these groups were compared. Planned subanalyses included stratification by the use of antihypertensive medications and a sensitivity analysis using the highest blood pressure during admission. Covariates included maternal age, preexisting diabetes mellitus or lupus erythematosus, and body mass index., Results: The analysis included 1,265,766 total birth encounters, 391,781 (30.9%) in the referent group (120/80 mm Hg), 392,592 (31.0%) in the group with <120/80 mm Hg, 249,414 (19.7%) in the group with ≥130/80 mm Hg, 16,125 (1.3%) in the group with ≥140/90 mm Hg, 50,659 (4.0%) in the group with ≥150/100 mm Hg, and 20,196 (1.6%) in the group with ≥160/110 mm Hg. In the first 6 weeks after delivery, readmission rates increased with higher blood pressure readings. More than 5% of postpartum patients with the highest blood pressure readings (≥160/110 mm Hg) were readmitted. These patients were almost 3 times more likely to be readmitted than patients whose highest blood pressure reading fell into the referent group (120/80 mm Hg) (odds ratio [OR], 2.90; 95% confidence interval, 2.69-3.12). Patients with blood pressures of >150/100 mm Hg (odds ratio, 2.72; 95% confidence interval, 2.58-2.87), >140/90 mm Hg (odds ratio, 2.03; 95% confidence interval, 1.95-2.11), and >130/80 mm Hg (odds ratio, 1.43; 95% confidence interval, 1.37-1.49) all had higher odds of readmission, whereas patients with a blood pressure of <120/80 mm Hg had a lower odds of readmission (odds ratio, 0.78; 95% confidence interval, 0.75-0.81). Patients who had higher blood pressures during admission but had improved control in the 24 hours before discharge had lower rates of readmission than those whose blood pressures remained elevated. In all blood pressure categories, patients who received an antihypertensive prescription had higher rates of readmission., Conclusion: In this large, national dataset, blood pressure control at discharge and readmission in the postpartum period were significantly correlated. Our data should inform postpartum hypertension treatment goals and the role of remote monitoring programs in improving maternal safety., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Background: The aim of this study was to evaluate the recovery rate of the left ventricular systolic function of women diagnosed with peripartum cardiomyopathy receiving specialized care in rural Tanzania., Methods: In this observational study, women diagnosed with peripartum cardiomyopathy at a referral center in rural Tanzania between December 2015 and September 2021 were included. Women diagnosed between February and September 2021 were followed prospectively, those diagnosed between December 2015 and January 2021 were tracked back for a follow-up echocardiography. All participants received a clinical examination, a comprehensive echocardiogram, and a prescription of guideline-directed medical therapy. The primary outcome was recovery of the left ventricular systolic function (left ventricular ejection fraction > 50%)., Results: Median age of the 110 participants was 28.5 years (range 17-45). At enrolment, 49 (45%) participants were already on cardiac medication, 50 (45%) had severe eccentric hypertrophy of the left ventricle, and the median left ventricular ejection fraction was 30% (range 15-46). After a median follow-up of 8.98 months (IQR 5.72-29.37), 61 (55%) participants were still on cardiac medication. Full recovery of the left ventricular systolic function was diagnosed in 76 (69%, 95% CI 59.6-77.6%) participants. In the multivariate analysis, a higher left ventricular ejection fraction at baseline was positively associated with full recovery (each 5% increase; OR 1.7, 95% CI 1.10-2.62, p = 0.012), while higher age was inversely associated (each 10 years increase; OR 0.40, 95% CI 0.19-0.82, p = 0.012)., Conclusion: Left ventricular systolic function recovered completely in 69% of study participants with peripartum cardiomyopathy from rural Tanzania under specialized care., (© 2024.

Objectives: To evaluate the impact of autoantibodies against the M2-muscarinic receptor (anti-M2-R) on the clinical outcomes of patients receiving the standard treatment for peripartum cardiomyopathy (PPCM)., Methods: A total of 107 PPCM patients who received standard heart failure (HF) treatment between January 1998 and June 2020 were enrolled in this study. According to anti-M2-R reactivity, they were classified into negative (n = 59) and positive (n = 48) groups, denoted as the anti-M2-R (-) and anti-M2-R (+) groups. Echocardiography, 6-min walk distance, serum digoxin concentration (SDC), and routine laboratory tests were performed regularly for 2 years. The all-cause mortality, cardiovascular mortality, and rehospitalisation rate for HF were compared between the two groups., Results: A total of 103 patients were included in the final data analysis, with 46 in the anti-M2-R (+) group and 57 in the anti-M2-R (-) group. Heart rate was lower in the anti-M2-R (+) group than in the anti-M2-R (-) group at the baseline (102.7 ± 6.1 bpm vs. 96.0 ± 6.4 bpm, p < 0.001). The initial SDC was higher in the anti-M2-R (+) group than in the anti-M2-R (-) group with the same dosage of digoxin (1.25 ± 0.45 vs. 0.78 ± 0.24 ng/mL, p < 0.001). The dosages of metoprolol and digoxin were higher in the anti-M2-R (-) patients than in the anti-M2-R (+) patients (38.8 ± 4.6 mg b.i.d. vs. 27.8 ± 5.3 mg b.i.d., p < 0.0001, respectively, for metoprolol; 0.12 ± 0.02 mg/day vs. 0.08 ± 0.04 mg/day, p < 0.0001, respectively, for digoxin). Furthermore, there was a greater improvement in cardiac function in the anti-M2-R (-) patients than in the anti-M2-R (+) patients. Multivariate analysis identified negativity for anti-M2-R as the independent predictor for the improvement of cardiac function. Rehospitalisation for HF was lower in the anti-M2-R (-) group, but all-cause mortality and cardiovascular mortality were the same., Conclusions: There were no differences in all-cause mortality or cardiovascular mortality between the two groups. Rehospitalisation rate for HF decreased in the anti-M2-R (-) group. This difference may be related to the regulation of the autonomic nervous system by anti-M2-R., (© 2021. The Author(s).)

Peripartum cardiomyopathy (PPCM) is a life-threatening heart failure occurring in the peripartum period. Although mal-angiogenesis, induced by the 16-kDa N-terminal prolactin fragment (16 K PRL), is involved in the pathogenesis, the effect of full-length prolactin (23 K PRL) is poorly understood. We transfected neonate rat cardiomyocytes with plasmids containing 23 K PRL or 16 K PRL in vitro and found that 23 K PRL, but not 16 K PRL, upregulated protein kinase RNA-like endoplasmic reticulum kinase (PERK) signaling, and hypoxia promoted this effect. During the perinatal period, cardiomyocyte-specific PERK homogenous knockout (CM-KO) mice showed PPCM phenotypes after consecutive deliveries. Downregulation of PERK or JAK/STAT signaling and upregulation of apoptosis were observed in CM-KO mouse hearts. Moreover, in bromocriptine-treated CM-KO mice, cardiac function did not improve and cardiomyocyte apoptosis was not suppressed during the peripartum period. These results demonstrate that interaction between 23 K PRL and PERK signaling is cardioprotective during the peripartum term., (© 2021. The Author(s).)

Introduction: Women with preeclampsia are more likely to have abnormal echocardiographic parameters at the time of diagnosis and are more likely to have hypertension and other cardiovascular diseases (CVD) later in life. Screening for future CVD in preeclamptic women would assist in appropriately risk stratifying and identifying high risk women for preventive management; however, the timing of screening and the screening factors are unknown., Objective: The objectives of this project are to 1) assess incidence of essential hypertension 4 years after pregnancy in preeclampsia with severe features (PEC) 2) identify predictive echocardiographic variables at the time of PEC diagnosis and 3) assess the rate of echocardiographic abnormalities 4 years after developing PEC., Study Design: This is a prospective longitudinal study observing the incidence of essential hypertension in women within 4 years of a pregnancy complicated by PEC. We further looked at echocardiographic variables at the time of PEC diagnosis and at 4 years after PEC pregnancy in women with and without subsequent incident essential hypertension. The primary outcome measure is the incidence of essential hypertension within 4 years of PEC pregnancy, defined as a systolic blood pressure ≥ 130 mmHg or a diastolic blood pressure ≥ 80 mmHg. Secondary imaging outcomes include the persistence of abnormal echocardiographic parameters. Clinical secondary outcomes are new diagnoses of severe CVD, including coronary artery disease, stroke, arrhythmia, heart failure, or inpatient hospital admission for CVD., Results: Of the 33 enrolled women with PEC, 48% (16/33) developed incident essential hypertension within 4 years of delivery. These women had thicker left ventricular posterior walls on their initial antenatal echocardiogram when compared to the 52% (17/33) who did not develop hypertension (1.0 cm [0.9-1.1 cm] vs 0.9 cm [0.7-0.9 cm]. p < 0.016). However, these abnormal echocardiographic variables resolved in the 16 women who underwent 4-year follow-up echocardiography., Conclusion: Women who develop PEC have a high incidence of essential hypertension within 4 years of delivery. The group who develops essential hypertension are more likely to have evidence of adverse cardiac remodeling at the time of PEC diagnosis; however, neither group have cardiac echocardiographic abnormalities 4 years postpartum. Because this is a small study, larger long-term cohort studies are needed to confirm these echocardiographic and clinical findings., (Copyright © 2021 International Society for the Study of Hypertension in Pregnancy.

Background: The aim of this study was to explore the risk factors associated with a poor left ventricular (LV) function among patients with peripartum cardiomyopathy (PPCM) and to determine the influence of acute kidney injury (AKI) on the LV function of the patients., Methods: Sixty patients with PPCM were recruited between January 2007 and June 2018, among which 11 had AKI. The participants were divided into two groups, the recovery group (32 cases) and the nonrecovery group (28 cases), with their clinical features, echocardiography and electrocardiogram findings, laboratory results, and treatments compared between groups. We further determined the risk factors associated with nonrecovery and the influence posed by AKI on the LV function of the patients., Results: Compared with the patients in the recovery group, those in the nonrecovery group had higher proportions of multiparity [78.6% (22/28) vs. 43.8% (14/32)], function class III- IV heart failure [92.9% (26/28) vs. 71.9% (23/32)], and a higher incidence of AKI [35.7% (10/28) vs. 3.1% (1/32)]. Logistic regression analysis showed that having AKI [odds ratio (OR): 10.556; 95% confidence interval (CI) 1.177-94.654; P = 0.035] and left ventricular ejection fraction (LVEF) < 40% [OR: 4.533; 95% CI 1.118-18.382; P = 0.034] were independently associated with nonrecovery of PPCM., Conclusions: The prognosis of patients with PPCM and AKI during hospitalization was poor compared to those without AKI; therefore, clinicians should pay more attention to this phenomenon.

Background: There are limited data on cardiovascular complications of coronavirus disease 2019 in pregnancy, and there are only a few case reports on coronavirus disease 2019 related cardiomyopathy in pregnancy. Differentiation between postpartum cardiomyopathy and coronavirus disease 2019 related cardiomyopathy in pregnant women who develop severe acute respiratory syndrome coronavirus-2 infection during peripartum could be challenging. Here, we present a case of possible coronavirus disease 2019 related cardiomyopathy in a pregnant patient, followed by a discussion of potential differential diagnosis., Case Presentation: In this case report, we present the case of a young pregnant Iranian woman who developed heart failure with pulmonary edema after cesarean section. She was treated because of low left ventricular ejection fraction and impression of postpartum cardiomyopathy, and her severe dyspnea improved by intravenous furosemide. On day 3, she exhibited no orthopnea or leg edema, but she was complaining of severe and dry cough. Further evaluation showed severe acute respiratory syndrome coronavirus-2 infection., Conclusions: The possibility of severe acute respiratory syndrome coronavirus-2 infection should be considered in any pregnant woman who develops cardiomyopathy and pulmonary edema.

Background: The use of extracorporeal membrane oxygenation (ECMO) as a rescue therapy for cardiopulmonary failure is expanding in critical care medicine. In this case series, we describe the clinical outcomes of 21 consecutive pregnant or postpartum patients that required venovenous (VV) or venoarterial (VA) ECMO. Our objective was to characterize maternal and fetal survival in peripartum ECMO and better understand ECMO-related complications that occur in this unique patient population., Methods: Between January 2009 and June 2019, all pregnant and postpartum patients treated with ECMO for respiratory or circulatory failure at a single quaternary referral center were identified. For all patients, indications for ECMO, maternal and neonatal outcomes, details of ECMO support, and anticoagulation and bleeding complications were collected., Results: Twenty-one obstetric patients were treated with ECMO over 10 years. Thirteen patients were treated with VV ECMO and 8 patients were treated with VA ECMO. Six patients were pregnant at the time of cannulation and 3 patients delivered while on ECMO; all 6 maternal and infant dyads survived to hospital discharge. The median gestational age at cannulation was 28 weeks (interquartile range [IQR], 24-31). In the postpartum cohort, ECMO initiation ranged from immediately after delivery up to 46 days postpartum. Fifteen women survived (72%). Major bleeding complications requiring surgical intervention were observed in 7 patients (33.3%). Two patients on VV ECMO required bilateral orthotopic lung transplantation and 1 patient on VA ECMO required orthotopic heart transplantation to wean from ECMO., Conclusions: Survival for mother and neonate are excellent with peripartum ECMO in a high-volume ECMO center. Neonatal and maternal survival was 100% when ECMO was used in the late second or early third trimester. Based on these results, ECMO remains an important treatment option for peripartum patients with cardiopulmonary failure., Competing Interests: Conflicts of Interest: See Disclosures at the end of the article., (Copyright © 2020 International Anesthesia Research Society.)

Peripartum cardiomyopathy (PPCM) is a form of heart failure that occurs toward the end of pregnancy or in the months following pregnancy and is marked by left ventricular systolic dysfunction. The cause of PPCM remains unknown and there is no diagnostic test specific to PPCM. Outcomes vary and include complete left ventricular recovery, persistent cardiac dysfunction, transplant, and death. Numerous advances have been made in understanding this disease, but many knowledge gaps remain. This article reviews recent data and recommendations for clinical practice in addition to highlighting the multiple knowledge gaps related to PPCM that warrant further investigation., Competing Interests: Disclosure The authors have nothing to disclose., (Copyright © 2020 Elsevier Inc.

Objective:  To evaluate the obstetric and sociodemographic characteristics of gestational diabetic women who maintained hyperglycemia in the postpartum period (6-12 weeks postpartum)., Methods:  This is a longitudinal cohort study with women who have had gestational diabetes and/or macrosomic children between March 1 st , 2016 and March 1 st , 2017. Between 6 and 12 weeks after birth, women who had gestational diabetes collected fasting glycemia, glucose tolerance test, and glycated hemoglobin results. The data were collected from medical records and during an interview in the first postpartum consultation. A statistical analysis was performed using frequency, percentage, Chi-Squared test, Fisher exact test, Mann-Whitney test, and multivariate Poisson regression. The significance level adopted for the statistical tests was 5%., Results:  One hundred and twenty-two women were included. Most of the women were younger than 35 years old (70.5%), white, multiparous, and with no history of gestational diabetes. Thirteen percent of the participants developed persistent hyperglycemia. A univariate analysis showed that maternal age above 35 years, being overweight, having grade 1 obesity and weight gain under 5 kg was related to the persistence of hyperglycemia in the postpartum period., Conclusion:  Maternal age above 35 years, obesity and overweight, and the diagnosis of gestational diabetes in the first trimester of pregnancy are associated with hyperglycemia during the postpartum period., Competing Interests: The authors have no conflict of interests to declare., (Federação Brasileira de Ginecologia e Obstetrícia.

Background: Peripartum cardiomyopathy (PPCM) is idiopathic pregnancy-associated heart failure (HF) with reduced left ventricular ejection fraction (LVEF). We aimed to assess arterial stiffness and left ventricular (LV) function in women recovered from PPCM compared with controls., Methods: Twenty-two PPCM patients were compared with 15 age-matched controls with previous uncomplicated pregnancies. Eleven of the patients were at inclusion in the study recovered and off medication since at least 6 months and still free from cardiovascular symptoms with normal LVEF and normal NT-proBNP. All underwent echocardiography, including LV strain, left atrial (LA) reservoir strain and tissue Doppler early diastolic velocity (e´) and non-invasive assessment for arterial stiffness and central aortic systolic blood pressure (AoBP) at rest and immediately postexercise., Results: The patients off medication showed alterations compared with controls. AoBP was higher (120 ± 9 mm Hg vs. 104 ± 13 mm Hg; p = .001), a difference which persisted postexercise. The arterial elastance was higher (1.9 ± 0.4 mm Hg/ml vs. 1.3 ± 0.2 mm Hg/ml; p < .001), while there were lower e´ septal (8.9 ± 1.7 cm/s vs. 11.0 ± 1.1 cm/s; p = 0. 002), LV global strain (18.7 ± 3.9% vs. 23.1 ± 1.6%; p = .004) and LA reservoir strain (24.8 ± 9.1% vs. 37.7 ± 6.3%; p = .002)., Conclusions: Compared with healthy controls, PPCM patients considered recovered and off medication had increased arterial stiffness, decreased LV longitudinal function and reduced LA function., (© 2020 The Authors.

Background: Compared with women without polycystic ovary syndrome, women with polycystic ovary syndrome have a higher prevalence of cardiometabolic risk factors. Postpartum weight retention has been shown to contribute to these risks in the general population, but little is known about postpartum weight retention among women with polycystic ovary syndrome., Objective: This study aimed to compare postpartum weight retention and peripartum weight trends between women with polycystic ovary syndrome and controls., Study Design: Data on live, full-term singleton deliveries from January 1, 2014, to January 1, 2019, in women with and without polycystic ovary syndrome were abstracted from the electronic medical record. Weights during the pregestational period, pregnancy, and up to 12 months postpartum were collected. The primary outcome was likelihood of high postpartum weight retention of ≥5 kg above pregestational weight at 12 months after delivery. Secondary outcomes included the prevalence of high weight retention at other postpartum time points (6 weeks, 3 months, 6 months), absolute postpartum weight retention, gestational weight gain, and excess weight gain above the Institute of Medicine guidelines for weight gain in pregnancy., Results: A total of 6333 women had the requisite weight information (pregestational, peak pregnancy, and at least 1 postpartum weight), including 429 (6.8%) with polycystic ovary syndrome. After adjusting for age, pregestational body mass index, race, gestational diabetes mellitus, and parity, women with polycystic ovary syndrome were less likely to be high weight retainers at 6 weeks after delivery (adjusted odds ratio, 0.71; P=.02). There was no difference in postpartum weight retention between groups at 3, 6, and 12 months after delivery. Overall, the prevalence of high weight retainers at 12 months after delivery was high in both groups (22.7% in polycystic ovary syndrome vs 29.2% in controls; P=.13), and there was no difference in absolute weight retention (1.69 kg in polycystic ovary syndrome vs 2.05 kg in controls; P=.25). Although women with polycystic ovary syndrome had a higher pregestational body mass index, they had lower gestational weight gain (median, 12.7 kg) than controls (median, 13.5 kg) (P=.01). These findings were driven by the group with obesity. The percentage of women who surpassed the Institute of Medicine guidelines for gestational weight gain based on the body mass index category was similar between groups (43.4% in polycystic ovary syndrome vs 47.3% in controls; P=.12). Overall, 18.5% of women with polycystic ovary syndrome and 23.4% of controls had a higher body mass index category at 12 months after delivery than before pregnancy., Conclusion: Women with polycystic ovary syndrome had lower gestational weight gain and lower likelihood of high weight retention at 6 weeks after delivery but similar weight retention at 12 months after delivery compared with controls. Overall, the large proportion of women with high postpartum weight retention highlights the importance of the peripartum time period for weight management, particularly in this high-risk group predisposed to obesity and cardiometabolic disease., (Copyright © 2020 Elsevier Inc.

Poor sleep in the postpartum is often treated as an unavoidable consequence of childbirth. This study aims to compare objective and subjective measures of sleep, explore the relationship between sleep and postpartum weight retention (PPWR), and investigate factors that may contribute to sleep quality in the postpartum period. In this cross-sectional cohort, PPWR, sleep quality (Pittsburgh Sleep Quality Index (PSQI)), and objective sleep and physical activity (accelerometry) were assessed in 109 women 0-52 weeks postpartum. Anthropometric and demographic data were collected. Gestational weight gain (GWG) was classified as inadequate, appropriate, or excessive according to Institute of Medicine guidelines. Average GWG (33.7 lbs) and PPWR (5.39 lbs) were not different between "good" (PSQI < 6) and "bad" (PSQI ≥ 6) sleepers. Following adjustment, mothers with excessive GWG who were "bad" sleepers had 5.26 higher odds of PPWR ≥ 10 lbs compared with all other combinations of GWG and PSQI. PSQI was not correlated with total sleep time (accelerometer-derived). Light activity and moderate-to-vigorous physical activity (MVPA) were associated with reduced odds of being a "bad" sleeper. The influence of GWG on PPWR was modified by postpartum sleep quality. Both light activity and meeting the MVPA guidelines in the postpartum were associated with higher sleep quality. Novelty Subjectively rated poor sleep may represent the number of awakenings and wake after sleep onset in postpartum women. Poor postpartum sleep quality increases excessive postpartum weight retention in women with excessive GWG. Women doing light-to-vigorous physical activity in the postpartum are less likely to experience poor sleep quality.

Background: Nigeria has the highest incidence of peripartum cardiomyopathy (PPCM) in the world. However, data on PPCM-related outcomes are limited., Objectives: The purpose of this study was to examine the clinical profile, myocardial remodeling, and survival of patients with PPCM in Nigeria., Methods: This study consecutively recruited 244 PPCM patients (median 7 months postpartum) at 14 sites in Nigeria and applied structured follow-up for a median of 17 months (interquartile range: 14 to 20 months). Left ventricular reverse remodeling (LVRR) was defined as the composite of left ventricular (LV) end-diastolic dimension <33 mm/m 2 and absolute increase in left ventricular ejection fraction (LVEF) ≥10%. LV full recovery was defined as LVEF ≥55%., Results: Overall, 45 (18.7%) patients died during follow-up. Maternal age <20 years (hazard ratio [HR]: 2.40; 95% confidence interval (CI): 1.27 to 4.54), hypotension (HR: 1.87; 95% CI: 1.02 to 3.43), tachycardia (HR: 2.38; 95% CI: 1.05 to 5.43), and LVEF <25% at baseline (HR: 2.11; 95% CI: 1.12 to 3.95) independently predicted mortality. Obesity (HR: 0.16; 95% CI: 0.04 to 0.55) and regular use of beta-blockers at 6-month follow-up (HR: 0.20; 95% CI: 0.09 to 0.41) were independently associated with reduced risk for mortality. In total, 48 patients (24.1%) achieved LVRR and 45 (22.6%) achieved LV full recovery. LVEF <25% at baseline (HR: 0.66; 95% CI: 0.47 to 0.92) and regular use of beta-blockers at 6-month follow-up (HR: 1.62; 95% CI: 1.17 to 2.25) independently determined the risk for LV full recovery. Progressive reverse remodeling of all cardiac chambers was observed. In total, 18 patients (7.4%) were hospitalized during the study., Conclusions: This is the largest study of PPCM in Africa. Consistent with late presentations, the mortality rate was high, whereas frequencies of LVRR and LV full recovery were low. Several variables predicted poor outcomes, and regular use of beta-blockers correlated with late survival and LV functional recovery., Competing Interests: Author Relationship With Industry The authors have received funding from Dantata Group of Companies, Ammasco International Ltd., and Fortune Oil Mills Nigeria Ltd.

The objective of this study was to evaluate the effects of clinical mastitis (CM) occurring before or after the first AI postpartum, and puerperal diseases (PD) on the pregnancy per artificial insemination (P/AI), number of AI/conception, and days open (DO) of two different dairy herds (Girolando and Holstein). The CM, PD (retained placenta and metritis), and reproductive data were collected from two dairy farms throughout 1 year. Both farms were located in the southern region of Minas Gerais State, Brazil. One herd was composed of Girolando cows and the other of Holstein cows. Cows were inseminated after estrus detection or submitted to timed AI. Only CM cases (clots in milk accompanied or not by udder inflammation) that occurred before or after first AI postpartum (from calving until 35 days after the first AI) were considered. There were no effects of CM, PD, or both diseases on the reproductive efficiency of the Girolando herd. In the Holstein herd, a reduce P/AI and prolonged DO were verified for those affected by ≥ 2 CM cases. Holstein cows with CM also required more inseminations to become pregnant. A decrease in the P/AI and an increase in the number of AI/conception and DO were observed in cows of the Holstein herd that developed only CM, only PD, and for those diagnosed with both diseases. In summary, considering that some management differences exist between the two dairy farms, CM occurrence (before or after the first AI postpartum) and puerperal diseases negatively affected the reproductive efficiency of the Holstein herd. However, these diseases did not compromise the reproductive efficiency of the Girolando herd.

Introduction: To classify persistent perineal and pelvic postpartum pain using the classification usually employed in chronic pelvic pain., Material and Method: Prospective observational study including all women who have consulted an algologist or gynecologist at one of the six French centers for a chronic pain (superior or equal to 3 months) spontaneous linked by the mother with her childbirth were included. During semi-directed interviews, a questionnaire regarding sociodemographic factors and detailed questions about pain were collected. Then, pelvic and perineal pain were classified into 7 pain syndromes: pelvic sensitization (Convergences PP criteria), complex regional pain syndrome (Budapest criteria), pudendal or cluneal neuralgia (Nantes criteria), neuroma, thoraco-lumbar junction syndrome, myofascial pain (muscle trigger zone), fibromyalgia (American College of Rheumatology criteria). The principal objective of this study is to assess the prevalence of each painful disorder. The secondary aims were the description of socio-demographic factors and clinical characteristics of this population, identify the related symptoms and the impact on daily function associated with the chronic pelvic or perineal postpartum pain., Results: 40 women with chronic pelvic or perineal pain spontaneously linked with childbirth were included. 78 % experienced pain for more than 12 months. A large majority had a vaginal birth (95 %) with perineal suture (90 %) and severe acute pain within the first week postpartum (62 %). Postpartum pain impacted participant's sexual activity (80 %), micturition (28 %) and defecation (38 %). In the sample, 17 cases of neuroma, 6 patients with pudendal or cluneal neuralgia, 13 patients with pelvic sensitization and 2 cases of fibromyalgia were identified. Complex regional pain syndrome was diagnosed in 8 patients, and myofascial pain in 11 women, and only 1 patient had thoraco-lumbar junction syndrome. Neuropathic pain was found in 31 participants (77.5 %) according to DN4 criteria., Discussion: The classification scheme proposed in this study may be a very useful tool to investigate postpartum pelvic and perineal pain and to propose a treatment., Competing Interests: Declaration of Competing Interest The authors have no conflicts of interest to declare., (Copyright © 2020 Elsevier Masson SAS.

Background: We studied the efficacy and safety of selenium supplementation in patients who had peripartum cardiomyopathy (PPCM) and selenium deficiency., Methods: We randomly assigned 100 PPCM patients with left ventricular ejection fraction (LVEF) < 45% and selenium deficiency (< 70 μg/L) to receive either oral Selenium (L-selenomethionine) 200 μg/day for 3 months or nothing, in addition to recommended therapy, in an open-label randomised trial. The primary outcome was a composite of persistence of heart failure (HF) symptoms, unrecovered LV systolic function (LVEF < 55%) or death from any cause., Results: Over a median of 19 months, the primary outcome occurred in 36 of 46 patients (78.3%) in the selenium group and in 43 of 54 patients (79.6%) in the control group (hazard ratio [HR] 0.69; 95% confidence interval [CI] 0.43-1.09; p = 0.113). Persistence of HF symptoms occurred in 18 patients (39.1%) in the selenium group and in 37 patients (68.5%) in the control group (HR 0.53; 95% CI 0.30-0.93; p = 0.006). LVEF < 55% occurred in 33 patients (71.7%) in the selenium group and in 38 patients (70.4%) in the control group (HR 0.91; 95% CI 0.57-1.45; p = 0.944). Death from any cause occurred in 3 patients (6.5%) in the selenium group and in 9 patients (16.7%) in the control group (HR 0.37; 95% CI 0.10-1.37; p = 0.137)., Conclusions: In this study, selenium supplementation did not reduce the risk of the primary outcome, but it significantly reduced HF symptoms, and there was a trend towards a reduction of all-cause mortality., Clinical Trial Registration: ClinicalTrials.gov Identifier: NCT03081949.

Objective: To evaluate postpartum MRI activity in patients with MS and a completed pregnancy and to compare these results to an age-matched untreated nonpregnant MS cohort., Methods: Patient with MS from a tertiary care MS center between 2006 and 2015, with prepartum and postpartum neurologic follow-ups and MRI scans were analyzed. Clinical activity and inflammatory brain MRI activity (new T2-hyperintense or gadolinium-enhancing [Gd+] lesions) were assessed peripartum. The results were compared with untreated reproductive-age patients with MS from the placebo arm of the clinical trials., Results: A total of 123 pregnancies in 123 women (median Expanded Disability Status Scale 1.0) were analyzed. Approximately 7.2% relapsed during pregnancy and 48.7% relapsed postpartum. Of pregnancies with prepartum and postpartum gadolinium (Gd)-enhanced MRI (n = 112), 8% had Gd+ lesions prepartum and 33% had new Gd+ lesions postpartum. Overall, 54.4% had either new T2 or Gd+ lesions postpartum. Seventy-nine percent of subjects with postpartum relapse had new MRI activity compared with 37.1% without relapse ( p < 0.001). Twenty-five percent had both clinical and radiographic activity and only 24.9% maintained no evidence of disease activity status postpartum. There was no association between postpartum MRI activity and disease-modifying treatments (DMTs) ( p > 0.5). MRI and clinical outcomes were also assessed for 126 nonpregnant untreated female patients with MS. Comparing pregnancy and no pregnancy groups, there was no difference in MRI activity at follow-up., Conclusions: There was a high level of inflammatory radiographic disease activity which was related to relapses in postpartum patients with MS. Further studies are needed to determine whether hormonal fluctuations vs extended time off DMTs may be the underlying cause of our observations., (Copyright © 2020 The Author(s).

The objective of this study was to assess how uterine disorders alter the lying behaviour and plasma biomarkers in dairy cows. 34 multiparous cows were retrospectively classified into three groups according to the first uterine disorder that cows were diagnosed with: retained placenta (RP), metritis (MET), or healthy (H; cows without any clinical disease). Lying time (LT) and duration of lying bouts (LB) were monitored between 6 weeks prior to and 8 weeks after calving via the AfiAct II pedometer. Blood samples were collected routinely between 14 days before and 28 days after calving. Data was analysed using Proc MIXED of SAS ver. 9.4. Regardless of grouping, both LT and LB were longer (P < 0.01) in the prepartum period (774 ± 16.6 min/day and 89.9 ± 2.1 min/bout) than in the first 28 days after calving (DFC; 653 ± 16.7 min/day and 63.7 ± 2.1 min/bout). Cows with RP had longer LT than healthy cows during the last 3 weeks before calving (837 ± 30.9 vs. 735 ± 27.1 min/day; P < 0.05). LT in cows with MET and healthy cows were not significantly different. The LB was similar among groups, averaging 76.1 ± 3.4 min/bout in healthy cows, 73.2 ± 3.8 min/bout in cows with RP, and 75.2 ± 3.7 min/bout in cows with MET (P > 0.05). Compared with healthy cows, cows with RP laid down longer and stood up for shorter times (P < 0.05), particularly before calving. In addition, cows with RP had increased mobilization of body stores and more pronounced inflammatory status, as demonstrated by plasma haptoglobin (P = 0.04) and albumin (P < 0.01) concentrations. Our data suggest that automatic monitoring of lying behaviour could help identify cows at increased risk of developing certain disorders, such as RP., (Copyright © 2020 Elsevier Ltd.

Aims: Peripartum cardiomyopathy (PPCM) is a life-threatening heart disease occurring in previously heart-healthy women. A common pathomechanism in PPCM involves the angiostatic 16 kDa-prolactin (16 kDa-PRL) fragment, which via NF-κB-mediated up-regulation of microRNA-(miR)-146a induces vascular damage and heart failure. We analyse whether the plasminogen activator inhibitor-1 (PAI-1) is involved in the pathophysiology of PPCM., Methods and Results: In healthy age-matched postpartum women (PP-Ctrl, n = 53, left ventricular ejection fraction, LVEF > 55%), PAI-1 plasma levels were within the normal range (21 ± 10 ng/mL), but significantly elevated (64 ± 38 ng/mL, P < 0.01) in postpartum PPCM patients at baseline (BL, n = 64, mean LVEF: 23 ± 8%). At 6-month follow-up (n = 23), PAI-1 levels decreased (36 ± 14 ng/mL, P < 0.01 vs. BL) and LVEF (49 ± 11%) improved. Increased N-terminal pro-brain natriuretic peptide and Troponin T did not correlate with PAI-1. C-reactive protein, interleukin (IL)-6 and IL-1β did not differ between PPCM patients and PP-Ctrl. MiR-146a was 3.6-fold (P < 0.001) higher in BL-PPCM plasma compared with PP-Ctrl and correlated positively with PAI-1. In BL-PPCM serum, 16 kDa-PRL coprecipitated with PAI-1, which was associated with higher (P < 0.05) uPAR-mediated NF-κB activation in endothelial cells compared with PP-Ctrl serum. Cardiac biopsies and dermal fibroblasts from PPCM patients displayed higher PAI-1 mRNA levels (P < 0.05) than healthy controls. In PPCM mice (due to a cardiomyocyte-specific-knockout for STAT3, CKO), cardiac PAI-1 expression was higher than in postpartum wild-type controls, whereas a systemic PAI-1-knockout in CKO mice accelerated peripartum cardiac fibrosis, inflammation, heart failure, and mortality., Conclusion: In PPCM patients, circulating and cardiac PAI-1 expression are up-regulated. While circulating PAI-1 may add 16 kDa-PRL to induce vascular impairment via the uPAR/NF-κB/miR-146a pathway, experimental data suggest that cardiac PAI-1 expression seems to protect the PPCM heart from fibrosis. Thus, measuring circulating PAI-1 and miR-146a, together with an uPAR/NF-κB-activity assay could be developed into a specific diagnostic marker assay for PPCM, but unrestricted reduction of PAI-1 for therapy may not be advised., (Published on behalf of the European Society of Cardiology.

Background The use of extracorporeal life support (ECLS) has expanded to include unique populations such as peripartum women. This systematic review aims to (1) quantify the number of cases and indications for ECLS in women during the peripartum period reported in the literature and (2) report maternal and fetal complications and outcomes associated with peripartum ECLS. Methods and Results This review was registered in PROSPERO (CRD42018108142). MEDLINE, Embase, and CINAHL were searched for case reports, case series, and studies reporting cases of ECLS during the peripartum period that reported one or more of the following outcomes: maternal survival, maternal complications, fetal survival, and/or fetal complications. Qualitative assessment of 221 publications evaluated the number of cases, clinical details, and maternal and fetal outcomes of ECLS during the peripartum period. There were 358 women included and 68 reported fetal outcomes in cases where the mother was pregnant at the time of cannulation. The aggregate maternal survival at 30 days was 270 (75.4%) and at 1 year was 266 (74.3%); fetal survival was 44 (64.7%). The most common indications for ECLS overall in pregnancy included acute respiratory distress syndrome 177 (49.4%), cardiac failure 67 (18.7%), and cardiac arrest 57 (15.9%). The most common maternal complications included mild to moderate bleeding 66 (18.4%), severe bleeding requiring surgical intervention 48 (13.4%), and intracranial neurologic morbidity 19 (5.3%). The most commonly reported fetal complications included preterm delivery 33 (48.5%) and neonatal intensive care unit admission 19 (27.9%). Conclusions Reported rates of survival in ECLS in pregnant and postpartum women are high and major complications relatively low.

Background: Fragmented QRS (fQRS) complex, with various morphology, has been recently described as a diagnostic criterion of several cardiac diseases. However, there are little data regarding the prognostic role of fQRS in peripartum cardiomyopathy (PPCM) patients. We aimed to investigate the effect of fQRS on predicting left ventricular (LV) nonrecovery in patients with peripartum cardiomyopathy (PPCM)., Methods: Ninety patients (mean age: 34.7 ± 6.5 years) with the diagnosis of PPCM were analyzed retrospectively. The median follow-up period of was 67.0 (12.0-192.0) months. Fragmented QRS was defined as the presence of various RSR' patterns (QRS duration < 120 ms) with or without Q wave, which include an additional R wave (R' prime) or notching of the R wave or S wave, or the presence of more than one R' (fragmentation) without typical bundle branch block. Recovery of LV function was defined as the presence of LV ejection fraction (EF) >45%., Results: Of the patients, 54 (60%) did not recover LV function at the last follow-up visit (nonrecovery group), while 36 of the patients (40%) exhibited LV recovery (recovery group). LV ejection fraction (EF) and fQRS were identified as independent predictors of LV nonrecovery in patients with PPCM (odds ratio OR: 5.546, 95% confidence interval CI: 0.792-0.979, p = .019 and OR: 5.986, 95% CI: 1.313-11.787, p = .014, respectively)., Conclusion: Our data firstly indicated that presence of fQRS was a significant predictor of LV nonrecovery in patients with PPCM. The fQRS might assist in identifying high-risk patients., (© 2019 The Authors. Annals of Noninvasive Electrocardiology published by Wiley Periodicals, LLC.)

Objective: There is limited literature on postpartum preeclampsia for process outcomes, clinical symptoms, and laboratory values., Method: Retrospective study comparing 3 groups of antepartum preeclampsia without postpartum preeclampsia (APNP; n = 43), antepartum preeclampsia with persistent postpartum preeclampsia (APYP; n = 59), and new onset postpartum preeclampsia (NEWYP; n = 18)., Results: For process outcomes, NEWYP had higher odds for readmission as compared to APYP [OR: 5.41, 95 % CI: 1.34, 21.56, p = 0.02]. For clinical symptoms of postpartum highest systolic blood pressure NEWYP had greater values as compared to both APYP [B = 19.95, SE = 3.84, p < 0.001] and APNP [B = 23.63, SE = 2.87, p < 0.001]. For laboratory values of serum creatinine, NEWYP had greater values as compared to both APYP [B = 0.15, SE = 0.05, p = 0.01] and APNP [B = 0.17, SE = 0.05, p = 0.002]., Conclusion: NEWYP may represent a different disorder from APNP and APYP. We recommend close monitoring of NEWYP by clinicians., Competing Interests: Declaration of Competing Interest The authors have no conflict of interest., (Copyright © 2020 Elsevier Masson SAS.

Peripartum cardiomyopathy (PPCM) is a life-threatening cardiomyopathy characterized by acute or slow progression of left ventricular (LV) systolic dysfunction (LV ejection fraction of <45%) late in pregnancy, during delivery, or in the first postpartum months, in women with no other identifiable causes of heart failure. PPCM patients display variable phenotypes and risk factor profiles, pointing to involvement of multiple mechanisms in the pathogenesis of the disease. The higher risk for PPCM in women with African ancestry, the prevalence of gene variants associated with cardiomyopathies, and the high variability in onset and disease progression in PPCM patients also indicate multiple mechanisms at work. Experimental data have shown that different factors can induce and drive PPCM, including inflammation and immunity, pregnancy hormone impairment, catecholamine stress, defective cAMP-PKA, and G-protein-coupled-receptor signalling, and genetic variants. However, several of these mechanisms may merge into a common major pathway, which includes unbalanced oxidative stress and the cleavage of the nursing hormone prolactin (PRL) into an angiostatic, pro-apoptotic, and pro-inflammatory 16 kDa-PRL fragment, resulting in subsequent vascular damage and heart failure. Based on this common pathway, potential disease-specific biomarkers and therapies have emerged. Despite commonalities, the variation in aetiology and mechanisms poses challenges for the diagnosis, treatment, and management of the disease. This review summarizes current knowledge on the clinical presentation of PPCM in the context of recent experimental research. It discusses the challenge to develop disease-specific biomarkers in the context of rapid changing physiology in the peripartum phase, and outlines possible future treatment and management strategies for PPCM patients., (Published on behalf of the European Society of Cardiology.

The clinical significance of poor nutritional status in patients with peripartum cardiomyopathy (PPCM) is not clearly understood. Prognostic nutritional index (PNI) is a simple nutritional assessment tool, which was first demonstrated to be valuable in patients with colorectal surgeries. We aimed to investigate the predictive value of PNI in patients with PPCM.A total of 92 patients diagnosed with PPCM were enrolled in this study. PNI was calculated using the following formula: 10 × serum albumin value (g/dL) + 0.005 × total lymphocyte count. The primary endpoint was defined as composite adverse cardiac events that included cardiac death or hospitalization due to worsening heart failure (HF). Cardiac death, hospitalization due to worsening HF, and persistent left ventricular (LV) systolic dysfunction were evaluated, respectively, as secondary endpoints.Primary composite endpoint was higher in the lower PNI group. After adjusting for other risk factors, PNI was found to be as an independent predictor of primary composite endpoint (odds ratio 0.805; 95% confidence interval 0.729-0.888; P < .001). In addition, PNI was significantly associated with secondary endpoints; persistent LV systolic dysfunction as well as cardiac death.This study identified nutritional status assessed by the PNI seems to be a novel predictor of adverse cardiovascular outcomes in patients with PPCM.

Background: Postpartum psychosis (PP) is the most severe psychiatric disorder associated with childbirth, and the risk is particularly high in women with a history of bipolar disorder, schizoaffective disorder or in those who have suffered previous episodes of PP. While studies in patients with psychosis not related to the puerperium have demonstrated that abnormalities in stress response are important risk factors for psychosis, it remains unknown whether this is also the case for PP., Methods: This study includes 30 postpartum women, assessed, on average, at postpartum week 14.8 ± 10.1 either with a current episode of PP (n = 14), or at-risk of PP because of a history of bipolar/schizoaffective disorder but who were well (n = 16), and a group of healthy women (n = 26). Details about recent stressful life events were obtained using the List of Threatening Experiences questionnaire, while perceived stress was evaluated using the Perceived Stress Scale. We estimated hypothalamic-pituitary adrenal (HPA) activity by measuring salivary cortisol at awakening; at 15, 30, and 60 min after awakening; at noon; and at 8 pm. An Area Under the Curve analysis was performed to assess the awakening response (AUCi) and cortisol levels during the day (AUCg). Immune markers, including high sensitivity C-Reactive Protein (hs-CRP) and Interleukin (IL)-1a, IL-1b, IL-2, IL-4, IL-6, IL-8, IL-10, Tumor Necrosis Factor (TNFa), Vascular Endothelial Growth Factor (VEGF), Interferon gamma (INFγ), Monocyte Chemoattractant Protein 1 (MCP-1), and Epidermal Growth Factor (EGF) were evaluated from peripheral blood samples., Results: Women with current PP reported more frequent recent stressful life events, and higher perceived stress than healthy women. They also showed an activation of the stress and immune response, with higher levels of cortisol AUCg and hs-CRP (but not of other inflammatory markers) than healthy controls. Women at-risk of PP who remained well had values on these measures that were intermediate between those of women with a current episode of PP and those of healthy women. Stress measures and markers of stress and immune response explained 78 % of the variance of in group status between PP and healthy women, and 46 % of variance of in group status between women at-risk and healthy women., Conclusion: These findings suggest that an immune-HPA axis dysregulation, together with current stress may represent an important underlying pathophysiological mechanism in the onset of psychosis after childbirth in vulnerable women., Competing Interests: Declaration of Competing Interest None to declare., (Copyright © 2019.

Background: Physiotherapists and midwives in primary healthcare often encounter women with an increased separation between the two rectus abdominis muscle bellies after pregnancy, a so-called increased inter recti distance (IRD). There are few studies on the contribution of increased IRD to the explanation of post-partum health complaints, and very little guidance in the literature for health professionals on the management of increased IRD. The aim of this study was to describe how physiotherapists and midwives in primary healthcare perceive the phenomenon of increased IRD and its management in women after childbirth., Methods: A purposeful sampling approach was used to select physiotherapists and midwives working in primary healthcare in three large county council healthcare organisations in Sweden having experience of encountering women with increased IRD after pregnancy. Sixteen physiotherapists and midwives participated in focus group discussions. Four focus groups with four participants in each were undertaken. A semi-structured topic guide was used to explore responses to the research questions and the discussions were analysed using qualitative content analysis., Results: We identified an overarching theme: Ambivalence towards the phenomenon increased IRD and frustration over insufficient professional knowledge. The theme included three categories: Uncertainty concerning the significance of increased IRD as a causal factor for functional problems; perceived insufficient professional knowledge base for the management of increased IRD; and lack of inter-professional collaboration and teamwork in the management of patients with increased IRD. Due to sparse and somewhat contradictory research findings and absence of clinical guidelines, the health professionals lacked basic preconditions for applying an evidence-based practice concerning increased IRD. They obtained their information about increased IRD from the media and fitness coaches, and hence were somewhat unsure about what to believe regarding the phenomenon., Conclusions: There was no consensus among the health professionals on how to best approach increased IRD in the clinical setting. Our findings stress the importance of more research to increase the professional knowledge base among physiotherapists and midwives. The findings highlight the urgent need for policies and clinical guidelines advising health professionals in the management of increased IRD and for facilitating inter-professional collaboration and teamwork.

Objective: To describe 2 cases from a single academic institution of improvement in stiff-person syndrome (SPS) symptoms during pregnancy and to review the clinical outcomes of SPS in 6 additional pregnancies described in the literature., Methods: Evaluation of clinical symptoms and treatment changes of disease state during pregnancy., Results: Seven patients with 9 pregnancies are described in women with a diagnosis of SPS. Six of 7 (86%) women were positive for glutamic acid decarboxylase (GAD65) antibody. In 5 of 9 (56%) pregnancies, symptomatic medications (antispasmodics) were significantly reduced with stabilization or improvement in symptoms through pregnancy. Nine live, healthy pregnancies resulted. All 7 (100%) women experienced worsening of symptoms after the birth of their children, and symptomatic therapies were resumed and/or increased., Conclusions: The immune pathogenesis of SPS continues to be explored. Immunomodulatory shifts during pregnancy may influence changes of clinical SPS symptoms and provide insight into the unique pathogenesis of SPS. Some women with SPS may be able to reduce symptomatic medications related to clinical improvement during pregnancy. Women with SPS may safely carry pregnancies to term, delivering healthy and unaffected babies., (Copyright © 2020 The Author(s).

Background: Acute stroke during pregnancy or within 6 weeks of childbirth is devastating for the mother and her family, yet data regarding incidence and contemporary trends are very limited., Objectives: This study sought to investigate the incidence and outcomes of acute stroke and transient ischemic attack during pregnancy or within 6 weeks of childbirth in a large database., Methods: The National Inpatient Sample was queried to identify women age ≥18 years in the United States with pregnancy-related hospitalizations from January 1, 2007, to September 30, 2015. Temporal trends in acute stroke (ischemic and hemorrhagic)/transient ischemic attack incidence and in-hospital mortality were extracted., Results: Among 37,360,772 pregnancy-related hospitalizations, 16,694 (0.045%) women had an acute stroke. The rates of acute stroke did not change (42.8 per 100,000 hospitalizations in 2007 vs. 42.2 per 100,000 hospitalizations in 2015; p trends  = 0.10). Among those with acute stroke, there were increases in prevalence of obesity, smoking, hyperlipidemia, migraine, and gestational hypertension. Importantly, in-hospital mortality rates were almost 385-fold higher among those who had a stroke (42.1 per 1,000 pregnancy-related hospitalizations vs. 0.11 per 1,000 pregnancy-related hospitalizations; p < 0.0001). The rates of in-hospital mortality among pregnant women with acute stroke decreased (5.5% in 2007 vs. 2.7% in 2015; p trends  < 0.001)., Conclusions: In this contemporary analysis of pregnancy-related hospitalizations, acute stroke occurred in 1 of every 2,222 hospitalizations, and these rates did not decrease over approximately 9 years. The prevalence of most stroke risk factors has increased. Acute stroke during pregnancy and puerperium was associated with high maternal mortality, although it appears to be trending downward. Future studies to better identify mechanisms and approaches to prevention and management of acute stroke during pregnancy and puerperium are warranted., (Copyright © 2020 American College of Cardiology Foundation.

Background: Multiple sclerosis (MS) predominantly affects women of child-bearing potential. Pregnancy in MS is still a controversial issue lacking standardized treatment recommendations., Objective: To examine the reciprocal effects of pregnancy, MS, and disease-modifying treatment (DMT)., Methods: We analyzed 387 pregnancies in 239 women with relapsing remitting multiple sclerosis (RRMS) and ⩾1 pregnancy, establishment of diagnosis >1 year before conception, and ⩾2 years of follow-up after delivery. Relapse rates and Expanded Disability Status Scale (EDSS) scores were compared in the year before conception, during pregnancy, and 2 years postpartum. Binary logistic regression was used to investigate predictors of risk for relapses and disability progression during pregnancy and postpartum., Results: Risk of relapse and disability progression during pregnancy was predicted by pre-conception relapse activity, higher EDSS score at conception, use of highly effective disease-modifying treatment (H-DMT) pre-conception, and prolonged washout period. Postpartum relapse and disability progression was associated with relapse activity pre-conception and during pregnancy and use of H-DMT pre-conception. Early restart of DMT reduced the risk of postpartum relapse., Conclusion: A personalized approach in planning pregnancy in women with MS while on H-DMT needs to be adopted. It seems reasonable maintaining natalizumab closer to conception and restarting the drug early postpartum to reduce the considerable risk of disease reactivation during early pregnancy and after delivery.

Objective: The purpose of this study was to validate a Japanese version of the Pelvic Girdle Questionnaire (PGQ) and to confirm that the Japanese version of the PGQ (PGQ-J) was as valid as the original version., Methods: This study involves 2 phases: (1) a cross-cultural adaptation study and (2) a cross-sectional study. The English PGQ was translated referring to the cross-cultural adaptation study process. Forty healthy pregnant or postpartum Japanese women participated. Women with pelvic girdle pain (PGP) completed the PGQ-J and 5 other instruments. Internal consistency, construct validity, test-retest reliability, ceiling and floor effects, and discrimination validity of the PGQ-J were analyzed., Results: The PGQ-J showed high internal consistency with a Cronbach α of .968, and an interclass correlation coefficient of .79. The content validity showed a high positive correlation with the Oswestry Disability Index and Disability Rating Scale., Conclusion: The PGQ-J was reliable and valid with high internal consistency and content validity for assessing disability owing to PGP in Japanese pregnant and postpartum women. The PGQ-J is expected to facilitate research and clinical practice for PGP in Japan and contribute to the welfare of postpartum women., (Copyright © 2020. Published by Elsevier Inc.)

Peripartum cardiomyopathy (PPCM) can lead to long-term systolic dysfunction, especially among black women. Hypertensive disorders of pregnancy (HDP) are the strongest risk factor for PPCM, but controversy remains on whether HDP predict a favorable outcome. Women with HDP are also often diagnosed with PPCM earlier than those without HDP. Our objective is to determine recovery of systolic function in patients with PPCM stratified by HDP, timing of diagnosis, and race. We conducted a retrospective cohort study of 220 patients (55% black) diagnosed with PPCM. Patients with PPCM and HDP were diagnosed earlier postpartum than patients without HDP ( P =0.013), an effect that was most pronounced in nonblack patients. Rates of left ventricular ejection fraction (LVEF) recovery were similar among PPCM patients with and without HDP (68.4% versus 62.6%, P =0.425). In contrast, patients with PPCM diagnosed after 1-month postpartum had lower rates of LVEF recovery than patients diagnosed <1-month postpartum (53.7% versus 69.9%, P =0.035). LVEF at time of diagnosis is a strong predictor of LVEF recovery, and patients with PPCM diagnosed after 1-month postpartum had lower baseline LVEF compared to patients presenting earlier ( P =0.041). The presence of HDP does not correlate with LVEF recovery in our racially diverse PPCM cohort. In contrast, early diagnosis portends a favorable outcome. Early diagnosis is associated with higher LVEF at presentation, likely explaining the improved outcomes in these women. These findings underscore the need for early monitoring and diagnosis, especially in at-risk and underserved populations.

Objective: To identify clinical risk factors associated with development of delayed-onset postpartum preeclampsia, and to characterize management and subsequent risk of cardiovascular disease., Methods: This is a case-control study of women admitted to the hospital with delayed-onset postpartum preeclampsia (defined as a new diagnosis of preeclampsia presenting between 48 hours and 6 weeks postpartum) compared with women with full-term, uncomplicated pregnancies without a hypertensive diagnosis or diabetes. Included women delivered between January 2014 and June 2018 at a single tertiary care center. Women with an antenatal diagnosis of preeclampsia or chronic hypertension were excluded. Univariate analysis was used to identify risk factors associated with delayed-onset postpartum preeclampsia and to compare rates of hypertension and antihypertensive medication use, with follow-up beyond 3 months postpartum among a subset of women in the control group who were matched 2:1 with women in the case group. Multivariable logistic regression was performed and included covariates identified in a backward stepwise approach., Results: Compared with women in the control group (n=26,936), women with delayed-onset postpartum preeclampsia (n=121) were significantly more likely to be of non-Hispanic black race (31.4% vs 18.0%), obese (39.7% vs 20.1%), and deliver by cesarean (40.5% vs 25.8%), all P<.01. For women diagnosed with delayed-onset postpartum preeclampsia, the median postpartum day of presentation was 7.0 (interquartile range 5.0-9.0), with 93.4% presenting secondary to symptoms, which was most commonly a headache. A majority (73.6%) underwent imaging studies, and 49.6% received intravenous antihypertensive agents. A total of 86 (71.0%) women with delayed-onset postpartum preeclampsia and 169 (72.8%) women in the control group had longer term information available, with a median follow-up time of 1.5 years (interquartile range 0.8-2.8). Delayed-onset postpartum preeclampsia was associated with higher blood pressures at 3 months postpartum or later (median systolic 130 mm Hg vs 112 mm Hg and median diastolic 80 mm Hg vs 70 mm Hg, P<.001)., Conclusion: Delayed-onset postpartum preeclampsia is associated with variable management strategies. There is substantial overlap between the clinical risk factors for delayed-onset postpartum preeclampsia and antepartum preeclampsia. Our findings suggest that delayed-onset postpartum preeclampsia is also associated with an increased risk of progression to chronic hypertension.

The management of women with brain tumors in the early post-partum period may be demanding as the patho-physiological changes that occur during pregnancy may also manifest in the early post-partum period. The aim of our paper is to report a case of late-onset post-partum pre-eclampsia after brain tumor surgery, complicated by posterior reversible encephalopathy syndrome (PRES) and reversible cerebral vasoconstriction syndrome (RCVS). Hemicraniectomy and intensive care management were necessary to obtain a favorable neurological outcome. The inherent literature on the subject is also analyzed through a systematic research. This is the first case of supratentorial decompressive hemicraniectomy in post-partum PRES, while there has been only one other case of posterior fossa decompression described in this cohort of patients. PRES and RCVS can complicate the neurosurgical management of women in the postpartum period. A careful evaluation of the clinical presentation is necessary as in some particular cases an aggressive medical and surgical treatment is required to obtain a favorable outcome., (Copyright © 2019 Elsevier B.V.

Objectives: To test the hypothesis that ibuprofen is equivalent to acetaminophen in its effect on postpartum blood pressure in women with gestational hypertension or preeclampsia without severe features., Study Design: Single-center randomized, crossover, equivalence trial among women with hypertensive disorders of pregnancy without severe features after vaginal delivery. Participants were assigned in a double-blind fashion to ibuprofen 600 mg or acetaminophen 650 mg every 6 h for 24 h followed by crossover to the other drug. We assessed clinical blood pressures and ambulatory blood pressure monitor measurements. Intention-to-treat analyses were performed using a linear mixed model adjusted for time period., Main Outcome Measures: The mean difference in systolic blood pressure through 24 h of drug exposure with an equivalence margin of 10 mmHg., Results: Of 185 screened women, 74 enrolled prior to delivery. Forty-three women remained eligible and were randomized to ibuprofen first (n = 20, 46.5%) or acetaminophen first (n = 23, 53.5%). A total of 37 women (86.0%) received study drug (ibuprofen first n = 19, acetaminophen first n = 18). Most participants were white (91.9%) and had gestational hypertension (86.5%); mean (SD) age was 31.0 (6.5) years. The mean adjusted difference in systolic blood pressure was 1.0 mmHg (95% CI, -3.7 to 5.7 mmHg), which was within the equivalence margin. A linear mixed model did not demonstrate a main effect of group assignment, nor did it show an interaction effect with time period., Conclusions: Among women with gestational hypertension and preeclampsia without severe features, ibuprofen is an equally safe option as acetaminophen with respect to postpartum blood pressure concerns., (Copyright © 2019 International Society for the Study of Hypertension in Pregnancy.

Cardiomyopathy is a group of disorders in which the heart muscle is structurally and functionally abnormal in the absence of other diseases that could cause observed myocardial abnormality. The most common cardiomyopathies are hypertrophic and dilated cardiomyopathy. Rare types are arrhythmogenic right ventricular, restrictive, Takotsubo and left ventricular non-compaction cardiomyopathies. This review of cardiomyopathies in pregnancy shows that peripartum cardiomyopathy is the most common cardiomyopathy in pregnancy. Peripartum cardiomyopathy develops most frequently in the month before or after partum, whereas dilated cardiomyopathy often is known already or develops in the second trimester. Mortality in peripartum cardiomyopathy varies from <2% to 50%. Few reports on dilated cardiomyopathy and pregnancy exist, with only a limited number of patients. Ventricular arrhythmias, heart failure, stroke and death are found in 39%-60% of high-risk patients. However, patients with modest left ventricular dysfunction and good functional class tolerated pregnancy well. Previous studies on >700 pregnancies in 500 women with hypertrophic cardiomyopathy showed that prognosis was generally good, even though three deaths were reported in high-risk patients. Complications include different types of supraventricular and ventricular arrhythmias, heart failure and ischaemic stroke. Recent studies on 200 pregnancies in 100 women with arrhythmogenic right ventricular cardiomyopathy have reported symptoms, including heart failure in 18%-33% of pregnancies. Ventricular tachycardia was found in 0%-33% of patients and syncope in one patient. Information on rare cardiomyopathies is sparse and only presented in case reports. Close monitoring by multidisciplinary teams in referral centres that counsel patients before conception and follow them throughout gestation is recommended., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Validated measures to assess intrusive thoughts and compulsive behaviors in postpartum women are few. In the present study, we investigated the psychometric properties of such a measure - a self-report version of the Parental Thoughts and Behaviors Checklist (PTBC). Via an online survey platform, 488 women who had given birth during the last year completed the PTBC along with measures of general obsessive-compulsive symptoms, depression, anxiety, parental stress and quality of life. Scores on the PTBC and its subscales showed good to excellent internal consistency, correlated in the expected direction with the other measures in the study, and discriminated between women with and without a history of OCD. Finally, exploratory factor analyses yielded nine thematic factors of intrusive thoughts and compulsive behaviors which largely corresponded to the themes identified by the developers of the interview-based version of the PTBC. This self-report version of the PTBC was found to possess good psychometric properties and to have a factor structure that largely overlapped with the structure of the interview-based version. Further evaluation of this version is needed, but the measure holds promise as a tool that may aid in the assessment of postpartum OCD in primary care and in psychiatric settings., (Copyright © 2019 Elsevier B.V.

Pregnancy and the postpartum period are periods of significant change in the immune and endocrine systems. This period of life is also associated with an increased risk of mental health disorders in the mother, and an increased risk of developmental and neuropsychiatric disorders in her infant. The collective data described here supports the idea that peripartum mood disorders in mother and developmental disorders in her infant likely reflects multiple pathogeneses, stemming from various interactions between the immune, endocrine and nervous systems, thereby resulting in various symptom constellations. In this case, testing the mechanisms underlying specific symptoms of these disorders (e.g. deficits in specific types of learning or anhedonia) may provide a better understanding of the various physiological interactions and multiple etiologies that most likely underlie the risk of mental health disorders during this unique time in life. The goal here is to summarize the current understanding of how immune and endocrine factors contribute to maternal mental health, while simultaneously understanding the impact these unique interactions have on the developing brain of her infant., (Copyright © 2019 Elsevier Inc.

Objectives: To determine factors that predict the need for antihypertensive treatment during early postpartum period among women with preeclampsia or gestational hypertension., Study Design: Retrospective cohort of 358 women., Main Outcome Measures: Demographic, clinical and laboratory data of 63 women diagnosed with preeclampsia or gestational hypertension during a singleton pregnancy and who needed antihypertensive agents during early postpartum period were compared to 295 who did not., Results: No difference was found between groups regarding age, parity, body mass index, or weight gain (p = 0.95, 0.19, 0.56, and 0.078, respectively). Early onset preeclampsia or gestational hypertension was diagnosed among 28.6% of the women who subsequently needed antihypertensive treatment, as compared to 4.1% who did not (p < 0.001). Antepartum, mean maximum blood pressure in the treated vs. untreated group was 165/109 mmHg vs. 150/100 mmHg, respectively (p = 0.001). Groups did not differ regarding symptoms of preeclampsia (38.7% vs. 31.5%, p = 0.273) or laboratory abnormalities. The group that received antihypertensive treatment during early postpartum period, had more preterm deliveries (p < 0.001) and Cesarean deliveries (p < 0.001), and more received magnesium sulfate during labor (p < 0.001). During the early postpartum period, mean maximum blood pressure was higher among the treated group (167/106 vs. 143/92, p = 0.001), as were symptoms of preeclampsia (p = 0.001). The groups were similar regarding laboratory abnormalities that define preeclampsia., Conclusions: Early onset preeclampsia or gestational hypertension, severe antepartum hypertension, magnesium sulfate during labor, preterm, and Cesarean delivery might be good predictors of the need for antihypertensive treatment during early postpartum period., (Copyright © 2019 International Society for the Study of Hypertension in Pregnancy.
