Effects of supportive hemodialysis on the management of a pregnant woman with advanced chronic kidney disease: a case report and literature review

BackgroundPregnancy in women with chronic kidney disease (CKD) is associated with an increased risk of adverse maternal and fetal outcomes, including worsening renal function, hypertension, proteinuria, preeclampsia, preterm delivery, stillbirth, and intrauterine growth restriction. Some pregnant women with CKD may require dialysis after conception. Clinical guidelines provide recommendations for optimal hemodialysis prescription in pregnant women undergoing maintenance hemodialysis for end-stage kidney disease. However, the timing of initiation and optimal doses of hemodialysis for pregnant women with non-dialysis advanced CKD remain uncertain.Case presentationWe describe the case of a 29-year-old woman with a history of CKD for at least 2 years. She was referred to our department with a serum creatinine level of 2.48 mg/dL and an estimated glomerular filtration rate of 20 mL/min/1.73 m2. Because she was found to be pregnant at the initial visit, she was referred to the Department of Obstetrics. At 23 weeks’ gestation, she was admitted due to threatened premature delivery and urinary tract infection, which were managed with ritodrine hydrochloride and antibiotics. Owing to maternal weight loss and asymmetrical fetal growth restriction, daily protein intake was increased from 40 g/day to 60–80 g/day. Additionally, supportive hemodialysis (three times per week) was initiated at 26 weeks’ gestation, and the pre-dialysis blood urea nitrogen (BUN) level was consistently maintained < 40 mg/dL. Consequently, the patient’s weight increased, and fetal growth recovered. Because her blood pressure increased particularly during and after dialysis sessions, dialysis was discontinued at 32 weeks’ gestation. Urinary protein increased to a nephrotic level, and blood pressure was poorly controlled by medication, suggesting the onset of preeclampsia. Thus, a cesarean section was performed at 33 weeks’ gestation, and she delivered a male baby weighing 1449 g. Following childbirth, the patient did not require hemodialysis.ConclusionsSupportive hemodialysis during pregnancy in women with advanced CKD can increase maternal protein intake without elevating BUN levels, leading to improved fetal growth.

Adverse childhood experiences predict anxiety during postpartum and early childhood parenting

Perinatal anxiety disorders (PAD) affect one in five pregnant/postpartum people and are associated with adverse maternal and child health outcomes. Effective treatment and prevention rely on early identification and management of risk factors. Our study fills a gap in literature about how maternal adverse childhood experiences (ACEs) relate to PAD during and beyond the postpartum period. Using longitudinal data from a population-based sample of mothers in Colorado, USA (N = 1116), we evaluated whether maternal ACEs predicted self-reported anxiety symptoms, measured six times between 3 and 36 months postpartum. A mixed mean model of anxiety was fit with ACEs as the predictor and maternal age, race, ethnicity, education, marital status, and parity as covariates. Controlling for sociodemographic covariates, mothers reporting four or more ACEs had significantly higher levels of anxiety than those reporting less than four ACEs (b = 0.84, 95% CI (0.53, 1.15), p<.001) over the three-year period. Mothers of younger age at time of birth (25–34 years vs. <24 years: b=-0.54, 95% CI (-1.00, −0.08), p=.02) and non-Hispanic ethnicity (b = 0.47, 95% CI (0.09, 0.85), p=.01) were also found to have higher anxiety over this period. Our findings support screening for and addressing maternal ACEs early in obstetric care and well-child visits through trauma-informed, strengths-based approaches that promote maternal, child, and intergenerational well-being.

Study Effect of Esomeprazole on the Treatment of Preeclampsia in Pregnant Women: A Double-Blind Clinical Trial Study

Background: Preeclampsia is one of the most serious complications of pregnancy, leading to various maternal and fetal complications. Objectives: This study aimed to determine the effect of oral esomeprazole in the treatment of preeclampsia in pregnant mothers. Methods: In this double-blind clinical trial, we compared oral esomeprazole with a placebo. The study population included 120 pregnant women with preeclampsia (60 in the esomeprazole 40 mg group and 60 in the placebo group) who were referred to Ba'ath Hospital in Sanandaj in 2023. Patient care and follow-up were conducted from the time of diagnosis of preeclampsia and inclusion in the study groups until delivery and the final condition of the baby. The outcomes investigated included prolongation of pregnancy and maternal, fetal, and neonatal outcomes. Results: The average delivery time in the esomeprazole group was 37.3 ± 1.2 weeks, compared to 37.5 ± 1.7 weeks in the placebo group, with no statistically significant difference (P = 0.75). The frequency of maternal outcomes, such as eclampsia, pulmonary edema, hemolysis, placental abruption, renal failure, hepatic hematoma, ascites, thromboembolism, and maternal death, was not statistically different between the esomeprazole and placebo groups, and no severe complications were observed in either group. Similarly, fetal outcomes, including intrauterine growth restriction (IUGR) and changes in fetal heart rate patterns, did not significantly differ between groups, with no instances of fetal or neonatal death observed. Additionally, neonatal outcomes, such as Apgar scores below 7, NICU admissions, mechanical ventilation, and other severe neonatal complications, were not significantly different between the two groups (P &gt; 0.05). Although the esomeprazole group showed a lower frequency of adverse maternal, fetal, and neonatal outcomes compared to the placebo group, these differences were not statistically significant. Conclusions: The frequency of adverse maternal, fetal, and neonatal outcomes was lower in the esomeprazole group than in the placebo group for most variables, but the differences were not statistically significant. Therefore, it cannot be concluded with certainty that esomeprazole is ineffective in preventing or controlling preeclampsia.

Combined detection of serum adiponectin and pregnancy-associated plasma protein A for early prediction of gestational diabetes mellitus.

Early diagnosis of gestational diabetes mellitus (GDM) reduces the risk of adverse perinatal and maternal outcomes. At present, the value of serum adiponectin (ADP) and pregnancy-associated plasma protein A (PAPP-A) in clinical practice for the diagnosis of GDM in early pregnancy is unclear. To investigate the predictive value of serum ADP and PAPP-A in GDM. The electronic medical record data of all pregnant women from Zhongshan People's Hospital from 2018 to 2021 were retrospectively collected and divided into GDM group and control group according to whether GDM occurred. ADP and PAPP-A levels of the 2 groups were detected in early pregnancy, and the related factors of GDM were analyzed by binary logistic regression analysis. Receiver operating characteristic (ROC) curves of ADP and PAPP-A in predicting GDM in the early pregnancy were plotted and their clinical predictive value was analyzed. The significance level for all statistical tests is 0.05. Compared with the non-GDM group, the ADP of the GDM group was significantly lower than that of the non-GDM group [(8.19 ± 2.24) vs. (10.04 ± 2.73)]mg/L, the difference between groups was statistically significant (P < .05), and the multiple of median (MoM) of PAPP-A was significantly lower than that of the non-GDM group (1.13 ± 0.52) versus (1.45 ± 0.61) (P < .05). Binary logistic regression analysis showed that elevated serum ADP and PAPP-A levels were negatively correlated with the subsequent development of GDM [odds ratio (OR) 95% confidence interval (95% CI)] was 0.626 (0.536, 0.816), 0.934 (0.908, 0.961), respectively, P < .05.ROC curve analysis showed that the sensitivity and specificity of ADP and PAPP-A in predicting gestational diabetes were79.1% and 58.6%, respectively, 92.7% and 73.1%, and respectively. The area under curve (AUC) is 0.755 for ADP and 0.770 for PAPP-A. The AUC of the combined detection was 0.867, both of which were higher than that of single index diagnosis, and the sensitivity and specificity of the combined detection were 0.958 and 0.853, respectively. In summary, PAPP-A and ADP levels are independent related factors affecting the occurrence of GDM. The combined detection of PAPP-A and ADP should be utilized in diagnosing GDM to improve pregnancy outcomes for pregnant women.

Early pregnancy high normal HbA1c: a high risk group?

To determine if high normal early pregnancy HbA1c (35-40mmol/mol), in the absence of diabetes, was associated with increased risk of adverse perinatal outcomes compared to normal HbA1c (<35mmol/mol). A retrospective chart review was carried out on all singleton births in the Wellington region from 1 July 2019 to 31 December 2019. Exclusion criteria were participants domiciled outside the Wellington region, HbA1c ≥50mmol/mol, pre-existing diabetes, gestational diabetes in current pregnancy, no HbA1c performed <20 weeks or the first HbA1c was taken at ≥20 weeks. Baseline characteristics, HbA1c and pregnancy outcomes were obtained. The primary outcome was birth weight and was analysed using multiple linear regression. There were 1,067 participants in the normal HbA1c (nHbA1c) group and 186 in the high normal HbA1c (hnHbA1c) group. There was no difference in birth weight between hnHbA1c and nHbA1c. hnHbA1c had significantly lower odds of post-partum haemorrhage and composite maternal adverse outcomes compared to nHbA1c (OR 0.52, 95% CI 0.35-0.76) and (OR 0.64, 95% CI 0.46-0.89). High normal HbA1c was not associated with increased risk of adverse perinatal outcomes in pregnant people who did not develop gestational diabetes.

Hidradenitis Suppurativa and Maternal and Offspring Outcomes

Hidradenitis suppurativa (HS) is associated with morbidity in persons of reproductive age, but the effect on maternal and offspring outcomes is understudied. To determine the association of HS with pregnancy outcomes and maternal and child morbidity in the long term. This population-based longitudinal cohort study with up to 16 years of follow-up took place between 2006 and 2022 in Quebec, Canada. . Maternal HS. Outcomes included hypertensive disorders of pregnancy, gestational diabetes, and other birth outcomes as well as the long-term risk of hospitalization up to 16 years after delivery. The study used adjusted log-binomial and Cox proportional hazards regression models to estimate the association between maternal HS and pregnancy outcomes or hospitalization following pregnancy. Outcomes in both mothers and offspring were assessed. There were 1 324 488 deliveries during the study, including 1332 (0.1%) among mothers with HS. Compared with patients without HS, patients with HS had a greater risk of hypertensive disorders of pregnancy (risk ratio [RR], 1.55 [95% CI, 1.29-1.87]), gestational diabetes (RR, 1.61 [95% CI, 1.40-1.85]), and severe maternal morbidity (RR, 1.38 [95% CI, 1.03-1.84]). In neonates, maternal HS was associated with risk of preterm birth (RR, 1.28 [95% CI, 1.07-1.53]) and birth defects (RR, 1.29 [95% CI, 1.07-1.56]). In the long term, HS was associated with 2.29 times the risk of maternal hospitalization (95% CI, 2.07-2.55) and 1.31 times the risk of childhood hospitalization (95% CI, 1.18-1.45), including hospitalization for respiratory, metabolic, psychiatric, and immune-related morbidity over time. This cohort study found that HS is associated with adverse maternal and offspring outcomes in the peripartum period and in the long term. Early detection and management of HS may help mitigate these outcomes.

If the first child is breech, overall outcomes for families with two children are similar regardless of the mode of the first birth

Cesarean section for breech presentation is often recommended. However, cesarean section affects future reproduction. The aim of this study was to assess the effect of mode of the first birth in breech on outcomes of the second birth and the two births together. This is a register-based nationwide cohort study including 23 062 women with a first singleton birth in breech ≥ 34 gestational weeks and a subsequent singleton birth in Sweden 2000–2019. Exposure was mode of first delivery. Main maternal outcome was a composite of fourth-degree perineal injury, postpartum hemorrhage requiring blood transfusion, hysterectomy, or death. Main infant outcome was a composite of stillbirth, extremely preterm birth (< 28 weeks), moderate to severe hypoxic ischemic encephalopathy, therapeutic hypothermia, or death. Outcomes were analyzed using multivariable logistic regression. In the first birth, the infant composite outcome affected < 1% in both groups but the risk was higher in the vaginal breech group (13/1525), compared with the breech CS group (27/21 537), aOR 7.06, 95% CI 2.91–17.1. In the second birth, the infant composite outcome affected < 1% in both groups but the risk was lower for the first vaginal breech group (3/1525) compared with the first breech CS group (152/21 537), aOR 0.26, 95% CI 0.08–0.84. There was no significant difference between the groups in risk of composite infant outcome in the two births assessed together, or in risk of composite maternal outcome. In total, the chance of a two-children family without maternal or infant severe adverse composite outcome was high and similar regardless mode of the breech first birth.

Gestational diabetes: an update sixty years after O'Sullivan and Mahan.

Sixty years after the landmark publication by O'Sullivan and Mahan, the current paper seeks to review and place into context the importance of gestational diabetes (GDM) both as a marker of increased risk of adverse maternal and fetal pregnancy outcomes and as an indicator of future maternal and infant health risks. We review the evolution of GDM as a diagnosis, the ongoing debate regarding diagnostic approaches, the underlying pathophysiology, the epidemiology and the importance of GDM in the context of the global epidemics of diabetes and obesity. Focusing on clinical management, we review lifestyle based therapy and pharmacotherapy for GDM, consider obstetric management and outline the short term and lifelong health risks posed by a GDM diagnosis.

Characterization of clinical infection and drug resistance of group B streptococcus in Chengdu, China

ObjectiveTo investigate the clinical infection characteristics and antibiotic resistance of Group B Streptococcus (Streptococcus agalactiae, GBS) in Chengdu, China, from 2019 to 2021, as well as to provide data to support rational clinical drug use. MethodsThis was a retrospective study to collect 203 culture-positive GBS strains isolated from January 2019 to December 2021 in Chengdu, China, all of which were identified by the VITEK 2 Compact automated microbial Bacterial identification instrument. Data were derived using WHONET 5.6 software. The sample type and ward distribution were counted. Pregnant women and newborns were screened from the original data and their pregnancy outcomes were calculated respectively. ResultsGBS strains were mainly concentrated in obstetrics and neonatology departments, accounting for 40.9 % and 33.5 %. The types of specimens were mainly vaginal secretions, amniotic fluid and sputum, accounting for 25.6 %, 26.1 % and 18.7 %, respectively. Chorioamnionitis, premature rupture of membranes and preterm delivery occurred mainly in pregnant women after infection, accounting for 44.4 %, 31.5 % and 24.1 %. Neonates, on the other hand, were mainly diagnosed with neonatal pneumonia, neonatal sepsis, respiratory failure and septic meningitis, accounting for 91.8 %, 61.2 %, 44.9 % and 16.3 % of all positive neonates. 840 pregnant women were screened for GBS colonization from 2019 to 2021, and a total of 108 GBS positive pregnant women were identified, with a GBS colonization rate of 12.9 %. A total of 9 neonates from 108 GBS positive pregnant women developed early-onset disease. The morbidity in neonates was 8.3 %. No strains resistant to penicillin and ampicillin were found, while the resistance rates of tetracycline and clindamycin were higher than 50 %, respectively 60.1 % and 53.2 %. ConclusionGBS infection mainly affected pregnant women and newborns in Chengdu, China, which can lead to adverse maternal and infant outcomes. Attention should be paid to strengthening general screening of GBS in perinatal urogenital secretions and the prevention strategy of IAP (intrapartum antibiotic prophylaxis). Antimicrobial therapy should be administered with appropriate antibiotics. Penicillin was still the first line drug for the treatment of GBS. These initiatives were important to reduce mother-to-child transmission and neonatal infections.

Maternal mental disorders and neonatal outcomes: Danish population-based cohort study.

Previous studies have indicated associations between maternal mental disorders and adverse birth outcomes; however, these studies mainly focus on certain types of mental disorders, rather than the whole spectrum. We aimed to conduct a broad study examining all maternal mental disorder types and adverse neonatal outcomes which is needed to provide a more complete understanding of the associations. We included 1 132 757 liveborn singletons born between 1997 and 2015 in Denmark. We compared children of mothers with a past (>2 years prior to conception; n = 48 646), recent (2 years prior to conception and during pregnancy; n = 15 899) or persistent (both past and recent; n = 10 905) diagnosis of any mental disorder, with children of mothers with no mental disorder diagnosis before the index delivery (n = 1 057 307). We also considered different types of mental disorders. We calculated odds ratios and 95% CIs of low birthweight, preterm birth, small for gestational age, low Apgar score, Caesarean delivery and neonatal death. Odds ratios for children exposed to past, recent and persistent maternal mental disorders suggested an increased risk for almost all adverse neonatal outcomes. Estimates were highest for children in the 'persistent' group for all outcomes, with the exception of the association between persistent maternal mental disorders and neonatal death (odds ratio 0.96, 0.62-1.48). Our study provides evidence for increased risk of multiple adverse neonatal outcomes among children of mothers with mental disorders, highlighting the need for close monitoring and support for women with mental disorders.

Nulliparous Individuals with Class III Obesity: Adverse Outcomes with Labor versus Planned Cesarean Delivery.

Individuals with class III obesity (body mass index [BMI] ≥ 40 kg/m2) are at increased risk of cesarean delivery (CD) and peripartum complications. We ascertained compositive neonatal and maternal adverse outcomes among individuals with class III obesity who labored versus had planned CD. This was a retrospective cohort study from 2016 to 2021 using the National Vital Statistics System database. Nulliparous individuals with class III obesity prepregnancy were included if they had singleton, nonanomalous pregnancies and delivered at 37 to 41 weeks of gestation. Individuals were excluded if they had hypertensive disorders or diabetes. The primary outcome was a composite neonatal adverse outcome (CNAO), consisting of Apgar score less than 5 at 5 minutes, assisted ventilation > 6 hours, neonatal seizure, or neonatal death. The secondary outcome was a composite maternal adverse outcome (CMAO) that included admission to the intensive care unit, maternal transfusion, uterine rupture, or unplanned hysterectomy. A sensitivity analysis using a CMAO without transfusion was performed. A multivariable Poisson regression model was performed to calculate adjusted relative risks (aRRs) with 95% confidence intervals (CIs). Of 192,298 individuals who met inclusion criteria, 169,676 (88.2%) labored and 22,622 (11.8%) had a planned CD. Compared with neonates delivered by planned CD, the risk of CNAO was significantly lower in those who delivered after labor (aRR: 0.79, 95% CI: 0.71-0.87). There was no significant difference in the risk of CMAO between groups (aRR: 1.11, 95% CI: 0.87-1.41). However, the risk of CMAO without transfusion was lower in individuals who labored (aRR: 0.57, 95% CI: 0.40-0.83). In nulliparous individuals with class III obesity, the risk of CNAO and of CMAO without transfusion were significantly lower in individuals who labored, versus those who had a planned CD. · Labor in class III obesity: 21% fewer adverse neonatal outcomes.. · Class III obesity: 43% less maternal morbidity with labor.. · Labor in nulliparous individuals with class III obesity is safe..

Assessment of Risk Factors Associated with Placenta Previa in a Tertiary Health Institution in Southeast Nigeria

Background: Placenta previa is a significant obstetric complication that can lead to adverse maternal and fetal outcomes. Understanding its risk factors is crucial for early diagnosis and management, particularly in healthcare settings in Nigeria. Objective: To assess the risk factors associated with placenta previa among pregnant women in a tertiary health institution in Southeast Nigeria. Materials and Methods: This prospective descriptive study was conducted over two years (January 2021 to December 2022) and included all pregnant women who delivered in the institution during this period. Data were collected using a structured, interviewer-administered questionnaire after obtaining informed consent from participants. Placenta previa was identified through abdominal ultrasonography, and all confirmed cases were managed according to the MacAfee regimen. Descriptive statistics and chi-square tests were used to analyze the data using SPSS version 26. Results: Out of the 8,766 deliveries recorded in the hospital during the period of this study, 94 (1.07%) were diagnosed with placenta previa. Significant associations were found between placenta previa and factors such as advanced maternal age (≥40 years, p=0.041), history of complications during previous pregnancies (p=0.039), previous cesarean section (p=0.009), history of placenta previa (p&lt;0.001), multiple pregnancies (p=0.001), bleeding during pregnancy (p&lt;0.001), and uterine surgeries apart from cesarean sections (p=0.001). Smoking history was also a significant risk factor (p&lt;0.001). Conclusion: The study identified several risk factors for placenta previa, including advanced maternal age, previous cesarean section, history of placenta previa, multiple pregnancies, uterine surgeries, and smoking. These findings highlight the importance of targeted interventions and close monitoring of at-risk pregnant women to reduce complications.

Factors associated with essential newborn care practices among non-institutional births in urban Bangladesh: evidence from Bangladesh Urban Health Survey 2021

ABSTRACT Background Non-institutional births remain prevalent in low- and middle-income countries, associated with a majority of adverse maternal and child health outcomes, including maternal and child mortality. Ensuring essential newborn care (ENC) practices for these non-institutional births is crucial for reducing these adverse outcomes. This study aimed to identify the prevalence, and factors associated with the adoption of ENC practices among non-institutional births in urban Bangladesh. Methods A total of 2,165 children’s data were analyzed, extracted from the 35,186 ever-married women interviewed in the 2021 Bangladesh Urban Health Survey. Six ENC components and their level (lowest/none, moderate, and highest) were considered as the outcome variables. Several socio-demographic factors were considered as the explanatory variables. Multivariate binary and multinomial logistic regression model were used to explore the association between outcome and explanatory variables. Results Approximately 49% of all mothers reported practicing the highest level of ENC. Among the individual components, the highest adherence was observed for the use of a disinfected instrument to cut the umbilical cord (90%). The likelihood of adopting the highest level of ENC practices was higher among mothers with relatively higher education and wealth quintiles and lower among those residing in slum and other urban areas of city corporations compared to non-slum areas. Mothers living in the Khulna and Sylhet divisions had a lower likelihood of adopting the highest level of ENC practices. Conclusion Awareness building programs are needed to educate the population, particularly mothers, about the importance of practicing ENC for improving maternal and child health outcomes.

MATERNAL AND PERINATAL OUTCOMES OF EARLY TRIMESTER BLEEDING

Bleeding per vagina is one of the most everyday presentations in the first trimester, with an incidence of 15- 25%. These pregnancies end up in pregnancy loss and multiple poor feto-maternal outcomes requiring early registration and treatment. Objectives: To evaluate for maternal perinatal outcomes in normal intrauterine pregnancies complicated by first-trimester vaginal bleeding Methods: This cohort study was conducted at the Gynecology and Obstetrics department of Lady Reading Hospital Peshawar from January 2024 till the required sample size is obtained in May 2024. Data were collected from 195 pregnant females. Women were divided into two groups. All pregnant women with singleton pregnancy and with or without vaginal bleeding during the first trimester, defined as up to the first 12 weeks of pregnancy, both delivering at our institute, were selected. Results: Miscarriage rates were notably higher in the exposed group (20.4% vs. 10.3%, OR 3.5, p=0.02), as were preterm births (22.4% vs. 15.5%, OR 2.8, p=0.01) and placental complications (12.2% vs. 5.2%, OR 4.2, p=0.03). The exposed group also had higher rates of postpartum hemorrhage (14.3% vs. 10.3%, OR 2.2, p=0.01), though cesarean section rates were similar between groups (30.6% vs. 30.9%, OR 2.0, p=0.15). Conclusion: It is concluded that early trimester bleeding is associated with an increased risk of adverse maternal and perinatal outcomes, including miscarriage, preterm birth, placental complications, and low birth weight.

The optic nerve sheath in hypertensive disorders of pregnancy and perinatal outcomes: a cohort study

BackgroundPreeclampsia is implicated in 14% of maternal deaths worldwide, mostly due to complications such as intracranial hemorrhage and cerebral edema. Cerebral edema increases intracranial pressure, which can be predicted by ultrasonographic measurement of the optic nerve sheath diameter (ONSD). Greater diameters have been reported in women with preeclampsia and eclampsia; however, data are lacking on the possible association with maternal and neonatal adverse outcomes. This study aimed to determine whether there is an association between hypertensive disorders of pregnancy and the ONSD, and between this measurement and maternal and neonatal adverse outcomes.MethodsThis was a cohort study involving 183 women in the third trimester of pregnancy or within 24 h following childbirth, distributed as follows: control group (n = 30), gestational hypertension (n = 14), chronic hypertension (n = 12), preeclampsia without severe features (n = 12), preeclampsia with severe features (n = 62), superimposed preeclampsia (n = 23) and eclampsia (n = 30). The participants underwent ocular ultrasonography, and data on maternal and neonatal outcomes were collected from the medical records. To compare the groups, analysis of variance was used for the normally distributed numerical variables and the Kruskal–Wallis test was used for variables with non-normal distribution. Two-tailed p-values ≤ 0.05 were considered statistically significant.ResultsOverall comparison between the seven groups showed no statistically significant difference in the mean ONSD (p = 0.056). Nevertheless, diameters were significantly greater in the eclampsia group compared to the control group (p = 0.003). Greater diameters were associated with maternal admission to the intensive care unit (ICU) (p < 0.01) and maternal near miss (p = 0.01). There was no association between ONSD and admission to the neonatal ICU (p = 0.1), neonatal near miss (p = 0.34) or neonatal death (p = 0.26).ConclusionsNo association was found between ONSD and the hypertensive disorders of pregnancy in the overall analysis; however, ONSD was greater in women with eclampsia compared to controls. Greater diameters were associated with maternal admission to the ICU and maternal near miss. These findings suggest a potential use for bedside ultrasound as an additional tool for stratifying risk in patients with hypertensive disorders of pregnancy.

7833 Gestational Diabetes Mellitus (GDM): A Weighted Spectrum of Clinical Outcomes

Abstract Disclosure: M. Moazzami: None. N. Venkatesan: None. K.S. Rajagopalan: None. A.V. Vella: None. A. Egan: None. Gestational diabetes mellitus (GDM) affects approximately 10% of pregnancies, with rates almost doubling in minority subgroups. Higher body mass index (BMI) is a significant GDM risk factor, and BMI ≥ 25kg/m2 is often used as a criterion in risk factor-based screening programs. However, up to 60% of individuals with GDM have a normal BMI, and it is unclear if this offers protection against associated adverse outcomes. Furthermore, many prior studies fail to address the fact that those of Asian descent require a lower BMI cut-off, given their different distribution of body fat. Our study evaluated GDM pregnancy outcomes using BMI as a risk indicator. We compared individuals with BMIs &amp;lt; 25 kg/m2, 25-30 kg/m2, and &amp;gt; 30 kg/m2. For individuals that self-identified as Asian, we adjusted BMI categories: &amp;lt;23 kg/m2 for normal weight, 23-30 kg/m2 for overweight, and &amp;gt;30 kg/m2 for obese. We identified 2212 subjects diagnosed with GDM via universal screening and Carpenter and Coustan criteria at our institution from 2018 - 22. In total, 508 (23.0%) were normal weight, 611 (27.6%) overweight, and 1093 (49.4%) obese. The average maternal age was 31 years. Higher proportions identified as Hispanic and non-White race in overweight and obese categories. Maternal adverse outcomes were higher in obese compared to overweight or normal BMI categories (cesarian delivery: normal 26.7 v overweight 28.3 v obese 22.7%, p&amp;lt;0.001; hypertensive disorders: normal 13.2 v overweight 12.5 v obese 22.7%, p &amp;lt;0.001). Pharmacological therapy was required in 50% with obesity versus 24.8% in normal, and 28.7% in overweight categories (p&amp;lt;0.001). While there were no differences in live birth rates across categories, infants born to mothers with obesity had a higher birthweight (normal 3.30 v overweight 3.38 v obese 3.45kg, p&amp;lt;0.001) and were more likely to have neonatal hypoglycemia (normal 28.7 v overweight 25.5 v obese 43.8%, p&amp;lt;0.001) and require intensive care unit admission (normal 8.4 v overweight 5.5 v obese 12.7%, p&amp;lt;0.001). Attendance at postpartum glucose testing varied across BMI categories with lower attendance in mothers with obesity followed by normal weight BMI (normal 40.75 v overweight 45.99 v obese 36.2%, p&amp;lt;0.001). Compared to overweight individuals, those with normal weight exhibited higher rates of postpartum glucose intolerance (12.4 v 6.9%, p =0.002). However, those with obesity had the highest rates of glucose intolerance (20.7%, p&amp;lt;0.0002). Individuals with normal weight had the highest rates of breastfeeding (normal 95.9 v overweight 92.8 v obese 91.4% p=0.006). This study highlights the nuanced relationship between BMI and pregnancy outcomes in GDM. While maternal obesity was associated with the poorest outcomes, those with normal BMI were not protected compared to overweight individuals, and experience higher rates of postpartum glucose intolerance.

Cesarean delivery in a tertiary institution of the Republic of Moldova: analysis using the Robson classification

BackgroundThe worldwide rise in cesarean section rate is a major public health concern and cause of significant debate. Despite multiple studies showing that higher cesarean rates may be associated with adverse maternal and perinatal outcomes, the number of cesarean births increases continuously. In the Republic of Moldova, the cesarean section has increased from 15.75% in 2012 to 27.42% in 2022, however, the perinatal mortality remains unchanged - constituting 11.6‰. In order to understand the factors that determine the increasing trend of cesarean section and to approach new strategies to reduce unnecessary surgical delivery, a standardized tool is needed to assess and compare cesarean section rates. ObjectiveTo assess changes in cesarean section rates and trends and to evaluate the contribution of different obstetrical populations to overall cesarean rates in Municipal Clinical Hospital using the Robson Classification. Study DesignA cohort study conducted at the Municipal Clinical Hospital in Chisinau. The study includes 13882 women who gave birth in 2017, 2019, and 2022 in this hospital. All births were classified into 10 Robson groups, using six basic variables (parity, cesarean section delivery in medical history, labor onset, number of fetuses, gestational age, and fetal presentation). Statistical data were collected and analyzed using the Epi INFO program. ResultsThe overall cesarean section rate was 20.02% (2779/13882) with a significant increase from 18.59% (809/4351) to 21.59% (1134/5252), P=0.0003. Approximately one-third 39.55% (1099/2279) of all cesarean deliveries were performed before the labor onset. The main contributor in all study years is Group 5 - 34.44% (957/2779). The next valuable group as a contributor to the overall cesarean rate are the women from Group 2 representing 14.14% (393/2779), followed by women of Group 1 with 11.98% (333/2779). ConclusionsThe use of the Robson Ten-groups classification offers a clear and detailed record of the cesarean section trends, and due to its simplicity and exclusivity, it can be implemented in the Republic of Moldova as well. The main contributors to the overall cesarean rate are women with a previous cesarean delivery - Group 5, followed by nulliparous women of Group 2 and Group 1.

7589 A Survey On the Current Status of Universal Screening Thyroid Indicators During Pregnancy in Real World Study

A Survey on the current status of universal screening thyroid indicators during pregnancy in real world study Background: Thyroid dysfunction and thyroid auto-immunity (TAI) are common in women of childbearing age, which have been proven to increase the risk of maternal and fetal adverse pregnancy outcomes. China has adhered to the strategy of universal screening for early pregnancy thyroid indicators since 2012, and is currently the only country that recommends universal screening. This study aimed to investigate the implementation situation of universal screening for thyroid indicators during pregnancy in real world study. Methods: We retrospectively collected medical record information from 18,932 women who underwent regular prenatal examinations at Peking University First Hospital from January 2014 to December 2016 until the end of pregnancy, grouping based on whether thyroid indicators were screened during pregnancy, and comparing the general characteristics and pregnancy outcomes. Furthermore, the treatment compliance status of women who took levothyroxine and antithyroid drugs (ATD) before pregnancy was also analyzed. Results: The screening rate for thyroid indicators in pregnancy was 88.7% in our hospital, 93.3% of pregnant women underwent screening in early pregnancy, with a median gestational age of 7.0 (6.6, 10.1) weeks. Non-screening ones were more inclined to be aged&amp;gt;40 years or &amp;lt;25 years, with a BMI ≥24 kg/m2, pluriparity (≥2), and without thyroid disease history prior to conception (P &amp;lt; 0.05). After correcting covariates, the risks of early miscarriage (8-12 weeks) (OR=21.96, 95% CI: 19.2, 25.1) and late miscarriage (12-28 weeks) (OR=3.0, 95% CI: 2.5, 3.6) were significantly higher in non-screening group than in the screening group, but there was no significant difference in the risk of preterm labor between the two groups (P=0.985). The achievement rate (0.23≤TSH&amp;lt;2.5uIU/mL, FT4 within normal range, 53.7%-64.2%) of early pregnancy thyroid function among levothyroxine intervention participants increased from 2014 to 2016. Compared with those in the thyroid function controlled group, the patients in the uncontrolled group had earlier screening gestational weeks (6.7 vs. 8.0 weeks), higher TPOAb positivity (58.6% vs. 44%), and a greater incidence of other autoimmune disorders (14.2% vs. 9.8%) (P&amp;lt;0.05). The achievement rate of early pregnancy thyroid function among ATD intervention participants ranged from 63.6 to 71.2%. Conclusions: The screening rate for thyroid indicators in pregnancy is nearly 90% in comprehensive hospitals. The lack of screening may be related to miscarriage to some extent. The current treatment compliance status pre-pregnancy neither for levothyroxine nor ATDs was not satisfactory. Presentation: 6/2/2024

Dyslipidemia in Pregnancy: A Systematic Review of Molecular Alterations and Clinical Implications.

Dyslipidemia in pregnancy presents unique clinical challenges due to its effects on maternal and fetal health. This systematic review hypothesizes that molecular alterations in lipid metabolism during pregnancy contribute to adverse pregnancy outcomes and seeks to identify the clinical implications of these changes. The rationale behind this review stems from the increased risk of complications such as preeclampsia, intrauterine growth restriction, and acute pancreatitis associated with dyslipidemia in pregnancy. The primary objective is to examine the interplay between lipid metabolism and pregnancy outcomes. To achieve this, a systematic review following PRISMA guidelines was conducted, with a comprehensive search of the PubMed database covering articles from January 2014 to June 2024. Inclusion criteria focused on studies assessing molecular alterations and clinical outcomes of dyslipidemia in pregnancy, while case reports and relevant clinical trials were analyzed to evaluate both maternal and fetal outcomes. A total of 12 studies were included in the final analysis. This study provided evidence of the need for early detection and management strategies to reduce risks. The outcomes revealed significant associations between dyslipidemia and adverse maternal outcomes such as preeclampsia, gestational diabetes, and pancreatitis, as well as fetal outcomes like preterm birth and fetal distress. Early lipid monitoring and intervention are crucial in mitigating these risks and suggests that a multidisciplinary approach is necessary to improve maternal and fetal health in pregnancies complicated by dyslipidemia.
