J Obstet Gynaecol Res 2024; 50:430-437. [PMID: 38148278 DOI: 10.1111/jog.15868] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Accepted: 12/11/2023] [Indexed: 12/28/2023]
Abstract
PURPOSE This study aimed to determine fatty acid binding protein-4 (FABP-4) concentrations in maternal serum of fetal growth restriction (FGR) pregnancies and controls of normal pregnancies. Furthermore, we hypothesized that the alterations in FABP-4 levels might correlate with FGR severity. METHODS We performed this prospective case-control study with 83 pregnant women. The study groups included 26 FGR pregnancies without abnormal fetal Doppler flow patterns and 25 pregnancies complicated with FGR accompanied by abnormal fetal Doppler flow patterns. RESULTS The median serum FABP-4 concentrations were significantly higher in the FGR cases with abnormal Doppler flow pattern group (2.09 ng/mL) than in the FGR cases without abnormal Doppler flow pattern group (1.62 ng/mL) and the control group (1.20 ng/mL, p < 0.001). A significant negative correlation was observed between maternal serum FABP-4 levels and time to birth from blood sample collection (r = -0.356 and p = 0.001), gestational week at birth (r = -0.386 and p < 0.001), and birth weight (r = -0.394 and p < 0.001). A 1.35 ng/mL cut-off value of serum FABP-4 level could be used to discriminate FGR cases with a 78.4% sensitivity and 60.6% specificity. The optimal cut-off value of FABP-4 levels as an indicator for the diagnosis of FGR with abnormal Doppler flow pattern was estimated to be 1.76 ng/mL, which yielded a sensitivity of 84.0% and a specificity of 75.8%. CONCLUSION FABP-4 is a crucial biomarker in the diagnosis and determining the severity of pregnancies with restricted fetal growth. We consider that FABP-4 is a powerful, reliable, and unique biomarker to diagnose FGR pregnancies.

Abstract
ELABELA, an early endogenous ligand for the G protein-coupled receptor APJ (apelin peptide jejunum, apelin receptor), has been known as an important regulator in cardiovascular homeostasis and may be a novel therapeutic target for multiple cardiovascular diseases (CVDs). At the physiological level, ELABELA exhibits angiogenic and vasorelaxant effects and is essential for heart development. At the pathological level, circulating ELABELA levels may be a novel diagnostic biomarker for various CVDs. ELABELA peripherally displays antihypertensive, vascular-protective, and cardioprotective effects, whereas central administration of ELABELA elevated BP and caused cardiovascular remodeling. This review highlights the physiological and pathological roles of ELABELA in the cardiovascular system. Enhancement of the peripheral ELABELA may be a promising pharmacological therapeutic strategy for CVDs.

Abstract
The apelinergic system is a highly conserved pleiotropic system. It comprises the apelin receptor apelin peptide jejunum (APJ) and its two peptide ligands, Elabela/Toddler (ELA) and apelin, which have different spatiotemporal localizations. This system has been implicated in the regulation of the adipoinsular axis, in cardiovascular and central nervous systems, in carcinogenesis, and in pregnancy in humans. During pregnancy, the apelinergic system is essential for embryo cardiogenesis and vasculogenesis and for placental development and function. It may also play a role in the initiation of labor. The apelinergic system seems to be involved in the development of placenta-related pregnancy complications, such as preeclampsia (PE) and intrauterine growth restriction, but an improvement in PE-like symptoms and birth weight has been described in murine models after the exogenous administration of apelin or ELA. Although the expression of ELA, apelin, and APJ is altered in human PE placenta, data related to their circulating levels are inconsistent. This article reviews current knowledge about the roles of the apelinergic system in pregnancy and its pathophysiological roles in placenta-related complications in pregnancy. We also discuss the challenges in translating the actors of the apelinergic system into a marker or target for therapeutic interventions in obstetrics.

Abstract
ObjectiveThis study aimed to detect Elabela concentrations in the serum of Missed abortion (MA) and compare them with the healthy pregnancies.Materials and methodsThis retrospective case-control study was performed in the second affiliated hospital, Xi'an Jiaotong University March 2019 to September 2019. A total of 108 healthy (35 early, 36 middle and 37 late) pregnant women and 25 (early gestational stage) MA patients were involved. Demographic and clinical characteristics were recorded. The concentration of plasma Elabela was examined using ELISA.ResultsThe level of plasma Elabela was increased in early and middle stages and decreased in late stage of healthy pregnant women. Maternal serum Elabela levels were significantly lower in MA patients (4.59 ± 1.23 ng/mL) compared to healthy pregnant women (5.77 ± 1.21 ng/mL, p < 0.01).ConclusionMaternal circulating levels of Elabela were significantly lower in MA patients than in healthy pregnant women. We consider that Elabela might be a crucial biomarker of the pathophysiologic process in MA.

Abstract
ÖZ
Amaç: Çalışmamızda COVID-19 pozitif gebelerde serum interlökin-6 ve interlökin-10 düzeyleri ile hastalığın seyri arasındaki ilişkinin araştırılması amaçlandı.
Yöntemler: Çalışmamızda 28 üçüncü trimester COVID-19 pozitif gebe ve 30 üçüncü trimester sağlıklı gebede serum IL-6 ve IL-10 düzeyleri ölçüldü. COVID-19 pozitif vakalar, taşıyıcı veya hasta olarak sınıflandırıldı. Çalışma grubundaki gebelerden 13'ü asemptomatik iken veya hafif hastalık nedeniyle takip edilirken; 7'si yoğun bakımda (YBÜ) olmak üzere toplam 15 hamile kadın hastaneye kaldırılarak tedavi altına alındı. COVID-19 pozitif gebe kadınların IL-6 ve IL-10 testleri ilk uygulama sırasında çalışıldı.
Bulgular: COVID-19'lu 7 (%25) hastanın yoğun bakım ünitesine kabul edilmesi gerekti. COVID-19 negatif gebelerde IL-6 düzeyi, COVID-19 taşıyıcısı ve hasta gebelere göre anlamlı derecede düşük bulundu (p=0,01). COVID-19 negatif olan gebelerde IL-10 düzeyi, COVID-19 taşıyıcısı olan gebelere (p=0,002) ve hastalara (p=0,002) göre anlamlı derecede yüksek bulundu.
Sonuç: Şüpheli veya doğrulanmış bir COVID-19 teşhisi ile başvuran hamile kadınlarda olumsuz sonuç riskini en aza indirmek için IL-6 ve IL-10 sitokin düzeylerinin yakından izlenmesi önerilir. Bu şekilde hamile kadınlarda orta-hafif COVID-19'u şiddetli COVID-19'dan ayırt etmek mümkün olabilir.

Abstract
OBJECTIVE This study aimed to detect aquaporin-9 (AQP9) concentrations in the serum of patients with preterm premature rupture of membranes (PPROM) and compare them with the healthy control group with intact membranes. MATERIAL AND METHODS We conducted this prospective case-control study from January 2020 to June 2020. Of the 80 pregnant patients included in the study, we enrolled 42 singleton pregnant patients with PPROM as the study group and 43 healthy gestational age-, and body mass index (BMI)-matched healthy pregnant women with intact fetal membranes as the control group. We compared demographic and clinical characteristics, complete blood count and biochemical parameters, and serum AQP9 concentrations of the participants. We constructed an ROC curve to illustrate the sensitivity and specificity performance characteristics of AQP9 and calculated a cutoff value by using the Youden index. RESULTS Maternal serum AQP-9 concentrations were significantly higher in patients with PPROM (804.46±195.63 pg/mL) compared to the healthy pregnant women in the control group (505.97±68.89 pg/mL, p<0.001). When we examine the area under the ROC curve (AUC), the AQP-9 value can be reflected as a statistically significant parameter for diagnosing PPROM. According to the Youden index, a 654.78 pg/mL cut-off value of AQP-9 can be utilized to diagnose PPROM with 80.5% sensitivity and 100% specificity. CONCLUSION Maternal serum AQP9 concentrations were significantly higher in PPROM patients than healthy pregnant women with an intact membrane. We suggest that AQP9 might be an essential biomarker of the inflammatory process and energy homeostasis in PPROM.

Abstract
PURPOSE This study aimed to determine the related antepartum and intrapartum factors of birth asphyxia among neonates born in a tertiary referral hospital. METHODS A total of 45 singleton pregnant women who delivered live births with a gestational age of ≥35 weeks and their neonates who suffered from birth asphyxia from June 2016 to June 2021 were included in this retrospective study. Data regarding maternal demographic features, maternal laboratory values, pregnancy complications, and obstetric and neonatal outcomes were collected. RESULTS Significant risk factors associated with birth asphyxia were nulliparity (odds ratio [OR] = 5.357, 95% confidence interval [CI] = 2.169-24.950, p = 0.001), placental abruption (OR = 8.667, 95% CI = 2.223-33.784, p = 0.002), intrauterine growth restriction (OR = 1.394, 95% CI = 1.109-8.631, p = 0.012), the prolonged second stage of labor (OR = 6.121, 95% CI = 2.120-17.595, p = 0.001), meconium-stained amniotic fluid (OR = 7.615, 95% CI = 2.394-24.223, p = 0.001), bloody amniotic fluid (OR = 9.423, 95% CI = 2.885-35.232, p = 0.001), the presence of FHR category II (OR = 12.083, 95% CI = 7.081-48.849, p <0.001) and FHR category III before labor (OR = 15.500, 95% CI = 8.394-56.176, p <0.001). CONCLUSION We identified that nulliparity, placental abruption, intrauterine growth restriction, the prolonged second stage of labor, meconium-stained or bloody amniotic fluid, and FHR tracings categories II and III were significantly associated with birth asphyxia.

Abstract
Objective To investigate the associations between serum uric acid (UA) and cystatin C (CysC) levels in late pregnancy with major unfavorable birth outcomes. Methods We retrospectively analyzed the maternal UA and CysC levels during late pregnancy and their relationship with unfavorable birth outcomes in a Chinese population (n = 11,580). Results Women with the highest quartile of UA had higher risks of low birth weight (LBW) and small for gestational age (SGA) babies and a lower risk of preterm birth (PTB) compared to women with the lowest quartile [for LBW, adjusted-odds ratio (OR) = 2.63, 95% CI: 1.76, 3.95; for SGA, adjusted-OR = 2.11, 95% CI: 1.73, 2.57; for PTB, adjusted-OR = 0.55, 95% CI: 0.45, 0.69; all P for trend <0.001]. Compared to women in the lowest quartile of CysC, higher risks of macrosomia and large for gestational age (LGA) and lower risks of PTB and SGA were observed for those in the highest quartile (for macrosomia, adjusted-OR = 2.01, 95% CI: 1.60, 2.51; for LGA, adjusted-OR = 1.97, 95% CI: 1.67, 2.32; for PTB, adjusted-OR = 0.32, 95% CI: 0.26, 0.41; all P for trend <0.001; for SGA, adjusted-OR = 0.78, 95% CI: 0.64, 0.96; P for trend <0.05). Conclusion This study reports the associations of maternal UA and CysC with adverse birth outcomes, and suggests that routine determination of maternal UA and CysC in late pregnancy is beneficial for assessing the risks of these outcomes.

Abstract
The apelinergic system, which includes the apelin receptor (APJ) as well as its two specific ligands, namely apelin and ELABELA (ELA/APELA/Toddler), have been the subject of many recent studies due to their pleiotropic effects in humans and other animals. Expression of these factors has been investigated in numerous tissues and organs—for example, the lungs, heart, uterus, and ovary. Moreover, a number of studies have been devoted to understanding the role of apelin and the entire apelinergic system in the most important processes in the body, starting from early stages of human life with regulation of placental function and the proper course of pregnancy. Disturbances in the balance of placental processes such as proliferation, apoptosis, angiogenesis, or hormone secretion may lead to specific pregnancy pathologies; therefore, there is a great need to search for substances that would help in their early diagnosis or treatment. A number of studies have indicated that compounds of the apelinergic system could serve this purpose. Hence, in this review, we summarized the most important reports about the role of apelin and the entire apelinergic system in the regulation of placental physiology and pregnancy.

Abstract
OBJECTIVES We aimed to evaluate maternal serum aquaporin-9 (AQP9) concentrations in patients with early-onset preeclampsia and compare them with the uncomplicated control group with normal blood pressure. METHODS This was a prospective case-control study including pregnant women who were diagnosed with early-onset preeclampsia between 200/7 -340/7 weeks of gestation. Demographic and clinical characteristics, complete blood count and biochemical parameters, and serum AQP9 concentrations were documented. A receiver operating characteristic (ROC) curve was constructed to illustrate the sensitivity and specificity performance characteristics of AQP9 and a cut-off value was estimated by using the Youden index. RESULTS The mean serum concentrations of maternal AQP9 were significantly increased in the early-onset preeclampsia group (722.22 ± 211.80 pg/mL) than the control group (499.97 ± 68.89 pg/mL, p < 0.001). When we analyze the area under the ROC curve (AUC), the serum AQP9 value can be considered a statistically significant parameter for diagnosing preeclampsia. According to the Youden index, a 587.70 ng/mL cut-off value of serum AQP9 level can be used to diagnose early-onset preeclampsia with 80.0% sensitivity and 89.7% specificity. CONCLUSION Maternal serum AQP9 concentrations were significantly increased in early-onset preeclampsia patients than healthy normotensive pregnant patients. We suggest that AQP9 might be a crucial biomarker of the inflammatory process in early-onset preeclampsia.
