Optimizing perinatal wellbeing in pregnancy with obesity: a clinical trial with a multi-component nutrition intervention for prevention of gestational diabetes and infant growth and neurodevelopment impairment. Front Med (Lausanne) 2024; 11:1339428. [PMID: 38681052 PMCID: PMC11045894 DOI: 10.3389/fmed.2024.1339428] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Accepted: 03/18/2024] [Indexed: 05/01/2024] Open
Abstract
Pregnancy complicated by obesity represents an increased risk of unfavorable perinatal outcomes such as gestational diabetes mellitus (GDM), hypertensive disorders in pregnancy, preterm birth, and impaired fetal growth, among others. Obesity is associated with deficiencies of micronutrients, and pregnant women with obesity may have higher needs. The intrauterine environment in pregnancies complicated with obesity is characterized by inflammation and oxidative stress, where maternal nutrition and metabolic status have significant influence and are critical in maternal health and in fetal programming of health in the offspring later in life. Comprehensive lifestyle interventions, including intensive nutrition care, are associated with a lower risk of adverse perinatal outcomes. Routine supplementation during pregnancy includes folic acid and iron; other nutrient supplementation is recommended for high-risk women or women in low-middle income countries. This study is an open label randomized clinical trial of parallel groups (UMIN Clinical Trials Registry: UMIN000052753, https://center6.umin.ac.jp/cgi-open-bin/ctr_e/ctr_view.cgi?recptno=R000060194) to evaluate the effect of an intensive nutrition therapy and nutrient supplementation intervention (folic acid, iron, vitamin D, omega 3 fatty acids, myo-inositol and micronutrients) in pregnant women with obesity on the prevention of GDM, other perinatal outcomes, maternal and newborn nutritional status, and infant growth, adiposity, and neurodevelopment compared to usual care. Given the absence of established nutritional guidelines for managing obesity during pregnancy, there is a pressing need to develop and implement new nutritional programs to enhance perinatal outcomes.

Color Doppler ultrasound in high-low risk pregnancies and its relationship to fetal outcomes: a cross-sectional study. Front Pediatr 2024; 11:1221766. [PMID: 38444769 PMCID: PMC10912586 DOI: 10.3389/fped.2023.1221766] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Accepted: 12/26/2023] [Indexed: 03/07/2024] Open
Abstract
Objective To calculate the multivessel color Doppler indices in high-risk and low-risk pregnancies and relate these to fetal outcomes. Methods The investigation involved 60 patients who were pregnant. The patients were separated into groups according to assessment of low and high risk. The patients underwent color Doppler ultrasonography to detect the maternal and fetal blood vessels, and the measured Doppler indices were then analyzed for any association with fetal outcomes. Results The gestational stages (in weeks) of the participants at the respective times of investigation and delivery were 32.06 ± 2.98 and 36.2 ± 1.78 in the low-risk group and 29.21 ± 1.95 and 29.83 ± 1.86 in the high-risk group. The pulsatility index (PI), resistive index (RI), and systolic/diastolic ratio (SD) decreased with gestation length in the low-risk group, whereas in the high-risk group, these values increased in the uterine and umbilical arteries. With increased gestational stage, MCA-PSV (peak systolic velocity) in the middle cerebral artery (MCA) increased, while PI decreased. Pulsatile and reversal flow of the uterine vein, the vein of Galen, and the umbilical vein were noted in high-risk pregnancies, and these negatively affected the fetal outcome. The fetal venous parameters were more specific and sensitive for predicting an unfavorable fetal outcome than the arterial factors, with a greater negative predictive value. Conclusion The results of our study indicate that abnormal Doppler indices of the blood vessels in high-risk pregnant patients will result in adverse clinical outcomes. Therefore, the patients can be monitored and managed accordingly using Doppler ultrasonography.

Effects of Recreational Therapy and 3D Ultrasonography for High-Risk Pregnancies on Psychological Well-Being during Hospitalization and in the Puerperal Phase. J Clin Med 2023; 12:6228. [PMID: 37834871 PMCID: PMC10573943 DOI: 10.3390/jcm12196228] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 09/24/2023] [Accepted: 09/25/2023] [Indexed: 10/15/2023] Open
Abstract
Hospitalization during pregnancy often produces psychosocial distress for pregnant women. In this study, 3D ultrasound and recreational therapy were compared to the standard treatment for their influence on depressive symptoms and anxiety. In this prospective one-year intervention study, women who were admitted to the hospital for any pregnancy complication, other than psychiatric, were included. A control group, with standard clinical treatment, and two intervention groups, both additionally receiving either 3D ultrasound or recreational therapy, were established. Psychological well-being was assessed at defined times by the PHQ-health-questionnaire. A total of 169/211 women were included: control group n = 79, 3D ultrasound group n = 43, and crochet group n = 83. A higher than estimated underlying depression was seen for all women on admission. The intervention groups showed less depression (p = 0.02762). No difference was seen between the intervention groups (p = 0.23029). Anxiety decreased throughout intervention, but not significantly. On admission, all women showed similar results of underlying depression, indicating that hospitalization itself already causes mild psychological stress. Both interventions decreased depressive symptoms. Intervention with either recreational therapy or 3D ultrasound can prevent the development of mild and major depression and decrease anxiety disorders, and therefore has a positive effect on well-being during hospitalization. These results emphasize the need to implement forms of interventions to improve the well-being of women, as this might improve pregnancy and neonatal outcome.

Role of First Trimester Screening Biochemical Markers to Predict Hypertensive Pregnancy Disorders and SGA Neonates-A Narrative Review. Healthcare (Basel) 2023; 11:2454. [PMID: 37685488 PMCID: PMC10487207 DOI: 10.3390/healthcare11172454] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Revised: 07/24/2023] [Accepted: 08/03/2023] [Indexed: 09/10/2023] Open
Abstract
Early recognition of high-risk pregnancies through biochemical markers may promote antenatal surveillance, resulting in improved pregnancy outcomes. The goal of this study is to evaluate the possibilities of using biochemical markers during the first trimester of pregnancy in the prediction of hypertensive pregnancy disorders (HPD) and the delivery of small-for-gestational-age (SGA) neonates. A comprehensive search was conducted on key databases, including PubMed, Scopus, and Web of Science, for articles relating to the use of biochemical markers in the prediction of HPD and SGA. The findings show that changes in the levels of biomarkers in the early pregnancy phases could be an important indicator of adverse pregnancy outcomes. The literature shows that low PAPP-A (pregnancy-associated plasma protein A) and PlGF (placental growth factor) levels, low alkaline phosphatase (AP), higher sFlt-1 (soluble fms-like Tyrosine Kinase-1) levels, higher AFP (alfa fetoprotein) levels, and elevated levels of inflammatory markers such as β-HGC (free beta human chorionic gonadotropin), interferon-gamma (INF-γ), and tumor necrosis factor-α (TNF-α) may be associated with risks including the onset of HPD, fetal growth restriction (FGR), and delivery of SGA neonates. Comparatively, PAPP-A and PlGF appear to be the most important biochemical markers for the prediction of SGA and HPD.

Role of Ultrasonography and Color Doppler in the Assessment of High-Risk Pregnancies and Their Accuracy in Predicting Fetal Outcome. Cureus 2023; 15:e39017. [PMID: 37323339 PMCID: PMC10265127 DOI: 10.7759/cureus.39017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/22/2023] [Indexed: 06/17/2023] Open
Abstract
Introduction Various methods are employed to evaluate the well-being of the fetus in high-risk pregnancies which consists of a biophysical profile (BPP), a non-stress test (NST), and daily fetal movements. Detection of aberrant blood flow in fetoplacental beds has been revolutionized by recent developments in ultrasound technology, such as color Doppler flow velocimetry. The cornerstone of maternal and fetal care is lowering maternal and perinatal mortality and morbidity is antepartum fetal surveillance. Doppler ultrasound is a non-invasive way of obtaining a qualitative and quantitative evaluation of maternal and fetal circulation and is utilized to investigate complications like fetal growth restriction (FGR) and fetal distress. Thus, it is useful in making distinctions between fetuses that are truly growth restricted and small for gestational age and healthy fetuses. The aim of the current study was to determine the role of Doppler indices in high-risk pregnancies and their accuracy in predicting fetal outcomes. Material and methods This prospective cohort study included 90 high-risk pregnancies in the III trimester (after 28 weeks of gestation) on whom ultrasonography and Doppler were performed. Ultrasonography was performed using PHILIPS EPIQ 5, a curvilinear probe of frequency 2-5MHz. Gestational age was determined with a biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femoral length (FL). Placental grading and position were noted. Estimated fetal weight and the amniotic fluid index were calculated. BPP scoring was done. Doppler study was conducted and the findings of Doppler indices that is pulsatility index (PI) and resistive index (RI) of the middle cerebral artery (MCA), umbilical artery (UA), and uterine artery (UTA), and cerebroplacental (CP) ratio in these high-risk pregnancies were documented and compared with standard. The flow patterns in MCA, UA, and UTA were also assessed. These findings were correlated with fetal outcomes. Results Among 90 cases, the common high-risk factor in pregnancy was preeclampsia without severe features (30%). Growth lag was present in 43 (47.8%) participants. Among the study population, HC/AC ratio was increased in 19 (21.1%) participants which indicates asymmetrical intrauterine growth restriction. Adverse fetal outcomes were seen in 59 (65.6%) of the subjects. CP ratio and UA PI had better sensitivity (83.05% and 79.66%, respectively) and positive predictive value (PPV) (87.50% and 90.38%, respectively) in identifying the adverse fetal outcomes. Diagnostic accuracy of CP ratio and UA PI (Accuracy=81.11%) was highest in predicting adverse outcomes than all the other parameters. Conclusion CP ratio and UA PI had better sensitivity, PPV, and diagnostic accuracy in identifying adverse fetal outcomes than other parameters. The study's findings support that the use of color Doppler imaging in high-risk pregnancies will help in the early identification of adverse fetal outcomes and aid in early intervention. This study is non-invasive, simple, safe, and reproducible. This study can also be performed bedside in high risk and unstable patients. This study is required to accurately assess fetal well-being in all high-risk pregnancies in order to improve fetal outcomes and to incorporate this procedure as a part of the protocol for the assessment of fetal well-being in these patients.

Abstract
Perinatal asphyxia is a major cause of severe brain damage and death. For its prenatal identification, Doppler ultrasound has been used as a surrogate marker of fetal hypoxia. However, Doppler evaluation cannot be performed continuously. We have evaluated the performance of a miniaturized multiparametric sensor aiming to evaluate tissular oxygen and pH changes continuously in an umbilical cord occlusion (UCO) sheep model. The electrochemical sensors were inserted in fetal hindlimb skeletal muscle and electrochemical signals were recorded. Fetal hemodynamic changes and metabolic status were also monitored during the experiment. Additionally, histological assessment of the tissue surrounding the sensors was performed. Both electrochemical sensors detected the pO2 and pH changes induced by the UCO and these changes were correlated with hemodynamic parameters as well as with pH and oxygen content in the blood. Finally, histological assessment revealed no signs of alteration on the same day of insertion. This study provides the first evidence showing the application of miniaturized multiparametric electrochemical sensors detecting changes in oxygen and pH in skeletal muscular tissue in a fetal sheep model.

Abstract
BACKGROUND Oligohydramnios is a predictor of fetal compromise and a useful tool in pregnancy management. It has been assessed using various techniques, including two-diameter pocket (2-DP) and amniotic fluid index (AFI). OBJECTIVES To determine which of these two techniques best diagnose oligohydramnios and predicts adverse perinatal outcomes. METHODS This was a comparative cross-sectional study conducted at Delta State University Teaching Hospital, Oghara in southern region of Nigeria over eight months period. One hundred high-risk pregnant women were recruited and ultrasound determination of amniotic fluid was performed using AFI and 2-DP. The women were followed up till delivery to determine adverse perinatal outcomes. RESULTS The indices of validity of AFI and the 2-DP were calculated and compared. The 2-DP had a higher sensitivity than AFI for adverse outcomes in high-risk pregnancies complicated by oligohydramnios. CONCLUSION The 2-DP technique should preferably be used for the assessment of oligohydramnios in high-risk pregnancies.

Abstract
The article presents a systematic review protocol. The aim of the study is an assessment of current studies regarding the application of artificial intelligence and neural networks in the screening for adverse perinatal outcomes. We intend to compare the reported efficacy of these methods to improve pregnancy care and outcomes. There are more and more studies that describe the role of machine learning in facilitating the diagnosis of adverse perinatal outcomes, like gestational diabetes or pregnancy hypertension. A systematic review of available literature seems to be crucial to compare the known efficacy and application. Publication of a systematic review in this category would improve the value of future studies. The studies reporting on artificial intelligence application will have a major impact on future prenatal practice.

Prenatal Attachment and Perinatal Depression: A Systematic Review. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17082644.

Abstract
Pregnancy is a period of complex bio-psychological changes, during which the development of an attachment bond to the fetus takes on a central role. Depressive symptoms are common during this period. Both symptoms of depression and low levels of prenatal attachment are related to negative outcomes in caregivers and infants. Following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement, this systematic review analyzes and systematizes 41 studies concerning the association between prenatal attachment and perinatal depression. The majority of the studies reported a significant association between the two. Specifically, prenatal depressive symptoms were found to be negatively associated with prenatal attachment. Furthermore, lower levels of prenatal attachment were related to higher postnatal depressive symptoms, although fewer studies assessed this association. While these results were found across different populations, conflicting findings emerged, suggesting they should be interpreted with caution, particularly in male samples and in non-normative pregnancies (e.g., high-risk pregnancies, medically assisted pregnancies, and pregnancies with previous perinatal losses). These results are clinically important for the perinatal screening process and for implementing preventive and treatment programs. However, future studies are needed to further confirm and generalize these results.

Abstract
BACKGROUND Soluble FMS-like Tyrosine Kinase 1 (sFlt-1) and placental growth factor (PlGF) have been reported to be highly predictive several weeks before the onset of preeclampsia. OBJECTIVE To investigate longitudinal changes of serum levels sFlt-1 and PlGF in pregnant women at high risk for the development of preeclampsia and to reveal an impact of aspirin on maternal serum concentrations of sFlt-1 and PlGF. METHODS This was a prospective longitudinal study in 394 women with various risk factors for the development of preeclampsia (chronic hypertension, antiphospholipid syndrome/APS or systemic lupus erythematosus/SLE, thrombophilia, women with a history of preeclampsia, pathologic first trimester screening for preeclampsia) and 68 healthy women. Serum levels of sFlt-1 and PlGF were measured prospectively at 4-week intervals (from gestational weeks 12 until postpartum). RESULTS The sFlt-1/PlGF ratio was significantly higher in women with an adverse obstetric outcome compared to women with a normal pregnancy, starting between 20 and 24 weeks of gestation. There was no effect of aspirin on sFlt-1/PlGF ratio in women with chronic hypertension, APS/SLE, thrombophilia and controls. The use of aspirin showed a trend towards an improvement of the sFlt-1/PlGF ratio in women with preeclampsia in a previous pregnancy and a significant effect on the sFlt-1/PlGF ratio in women with a pathologic first trimester screening for preeclampsia. CONCLUSIONS Our findings reveal an impact of aspirin on sFlt-1/PlGF ratio in women with a pathologic first trimester screening for preeclampsia, strongly supporting its prophylactic use.

OBJECTIVES To note the value of serum Vitamin B12, folic acid, and ferritin in normal and high-risk pregnancies (HRPs) in patients attending antenatal clinic at All India Institute of Medical Sciences (AIIMS). MATERIALS AND METHODS This is a cross-sectional study where a total of 282 patients attending Gynaecology Outpatient Department at AIIMS, New Delhi, India were recruited. Among the 282 subjects, 251 were pregnant, and 31 were controls. The serum was tested for serum Vitamin B12, serum folic acid, and serum ferritin levels using Beckman Coulter Access 2 immunoassay. RESULTS The median value of serum folic acid level in pregnant women was 12 pg/ml with range being 2-20 pg/ml in contrast to 8 pg/ml with range being 3-20 pg/ml in nonpregnant female. This difference was statistically significant. (P = 0.05). There was no significant difference in the median level of serum Vitamin B12 and serum ferritin in pregnant and nonpregnant group. Serum Vitamin B12 level was lower in the third trimester (127 pg/ml) than in first trimester (171 pg/ml) and the difference is statistically significant (P = 0.03). Serum ferritin levels were also significantly lower in the second trimester (16.4 pg/ml) than third trimester (24.55 pg/ml). Although the median serum folic acid level was lower in the first trimester (9.84 pg/ml) than in second trimester (10.8 pg/ml) and in the third trimester (13.18 pg/ml) but the difference was not statistically significant. There was no significant difference in Vitamin B12 level in HRPs (median value 134 pg/ml) as compared to low-risk pregnancies (149.5 pg/ml). CONCLUSION Serum folic acid levels are significantly higher during pregnancy as compared to nonpregnant state. However, there was no significant difference in the median level of serum Vitamin B12 and serum ferritin in pregnant and nonpregnant group. Serum folic acid level and ferritin level were significantly higher in HRPs compared to low-risk pregnancies.

Abstract
OBJECTIVE To assess whether the presence of autoantibodies has any effect on recurrent pregnancy loss (RPL) and obstetric complications in women who do not have autoimmune diseases and hereditary thrombophilia. METHODS Retrospectively, 515 patients who underwent antibody investigation with anti-nuclear antibody, extractable nuclear antigen, anti-double stranded DNA, anti-parietal cell, anti-smooth muscle, anti-mitochondrial (AMA), anti-thyroid peroxidase, anti-thyroglobulin (anti-TG) and anti-phospholipid (aPL) at Hacettepe University were included. Of those patients, 212 had one or more autoantibodies whereas the remaining 303 were negative for all autoantibodies. RPL was the primary outcome and was defined as ≥2 pregnancy losses (n = 119). RESULTS The frequency of RPL was significantly higher in the autoantibody positive group than controls (28.3% versus 14.5%, p<0.001). Anti-TG (21.2% versus 7.8%, p < 0.001), aPL (18.3% versus 5.6%, p < 0.001) and AMA (4.8% versus 0.5%, p = 0.001) antibodies were more common in patients with RPL. For the view of obstetric complications, oligohydramniosis (3.8% versus 0.7%, p = 0.03) and stillbirth (17.0% versus 10.6%, p = 0.002) were significantly higher in the autoantibody-positive group. CONCLUSIONS Even in women without autoimmune disease or hereditary thrombophilia, autoantibodies per se might directly increase the risk of RPL and obstetric complications. The screening anti-TG and aPL autoantibodies in the first step might be considered in patients with RPL.

Abstract
OBJECTIVE There are no national reports on the mode of delivery in pregnancies that end in stillbirth. We aimed at analyzing the cesarean delivery rates in pregnancies resulting in stillbirth over a 10-year period in the United States. MATERIALS AND METHODS This was a retrospective analysis evaluating data from the 1995 to 2004 US linked live birth-infant death files reported by the National Center for Health Statistics to examine the cesarean delivery rates in singleton pregnancies with and without stillbirth. RESULTS There were 39 797 616 singleton births registered in the database after the 20th week of gestation. During the study period, there were 243 979 stillbirths (0.61 per 100). Significant differences in stillbirths were noted in the African American population, nonmarried patients, in mothers who smoked, and at the extremes of the patients reproductive age (P < .01). The overall cesarean delivery rate in liveborn was 23.54% (9 309 961 cases) and 10.5% in stillbirth (25 558 cases; P < .01). The rate of cesarean delivery increased in liveborn (from 20.8% in 1995 to 28.9% in 2004; 28% overall increase) and in stillbirth (9.5% in 1995 to 11.23% in 2004; 15% overall increase). The rates of primary and repeat cesarean operations increased with gestational age in the stillbirth group. This pattern was not observed in the liveborn group. CONCLUSION This analysis indicates that the cesarean delivery rates increased both in liveborn and in stillbirth from 1995 to 2004. This epidemiological observation deserves new clinical investigations to understand the clinical reasons, driving this obstetrical practice and the financial and societal impact that it portends.

Abstract
AIM To study the role of Doppler imaging in prediction of high-risk pregnancies and their outcomes. METHODS AND MATERIAL This prospective study in a setup of tertiary-level care center includes 500 high-risk pregnant women from rural and urban sectors and evaluates the predictive values of various Doppler indices. RESULTS Out of 500 patients, 110 patients had abnormal Doppler among them, 70 patients had abnormal uterine artery Doppler, and 50 patients had abnormal umbilical artery Doppler flow indices. In all, 10 patients had both umbilical artery and uterine artery abnormal Doppler indices. When uterine artery was abnormal (70 patients), 20 patients had preeclampsia, 10 patients had pregnancy-induced hypertension (PIH), and 25 patients had intrauterine growth restriction (IUGR). Systolic/diastolic (S/D) ratio and notch had sensitivity of 60% and positive predictive value of 33.3% and 37.5%, respectively. When umbilical artery was abnormal (50 patients), 10 had preeclampsia, 15 had PIH, and 15 had IUGR. S/D ratio had the highest positive predictive value of 40%; sensitivity is same for all. In uterine artery, combination of parameters had the best sensitivity of 80%, followed by notch and S/D ratio. In umbilical artery, combination of parameters, S/D ratio, and RI (resistance index) had sensitivity of 40%; specificity of all the indices was 91–96%. In all, 20 patients had bilateral notch, and among them 15 developed preeclampsia and 15 developed IUGR. When both uterine and umbilical artery Doppler were abnormal (10 patients), all patients had preeclampsia and IUGR. CONCLUSION Therefore, Doppler study may be used for the prediction of preeclampsia and IUGR to reduce the maternal and perinatal morbidity and mortality.

Abstract
OBJECTIVE Use of assisted reproductive technology has increased steadily, yet multiple socioeconomic and demographic disparities remain between the general population and those with infertility. Additionally, both mothers and infants experience higher rates of adverse outcomes compared to their non-ART counterparts. METHODS Using International Classification of Diseases, Ninth Revision (ICD-9) coding, we performed a retrospective review of all ART-conceived deliveries in California in 2009. A total of 551 ART pregnancies were compared to Non-ART pregnancies (n=406,885). RESULTS The majority of ART deliveries belonged to women of advanced maternal age (AMA) and Caucasian or Asian race. Nearly half of all ART deliveries were multiple gestations. Compared to non-ART deliveries, ART pregnancies were associated with placenta previa, placental abruption, mild preeclampsia, and fetal growth restriction. CONCLUSION While not powered to detect all outcomes, our study highlights significant racial and ethnic disparities between ART and Non-ART pregnancies.
