Abstract
Targeted neonatal echocardiography (TNE) involves the use of comprehensive echocardiography to appraise cardiovascular physiology and neonatal hemodynamics to enhance diagnostic and therapeutic precision in the neonatal intensive care unit. Since the last publication of guidelines for TNE in 2011, the field has matured through the development of formalized neonatal hemodynamics fellowships, clinical programs, and the expansion of scientific knowledge to further enhance clinical care. The most common indications for TNE include adjudication of hemodynamic significance of a patent ductus arteriosus, evaluation of acute and chronic pulmonary hypertension, evaluation of right and left ventricular systolic and/or diastolic function, and screening for pericardial effusions and/or malpositioned central catheters. Neonatal cardiac point-of-care ultrasound (cPOCUS) is a limited cardiovascular evaluation which may include line tip evaluation, identification of pericardial effusion and differentiation of hypovolemia from severe impairment in myocardial contractility in the hemodynamically unstable neonate. This document is the product of an American Society of Echocardiography task force composed of representatives from neonatology-hemodynamics, pediatric cardiology, pediatric cardiac sonography, and neonatology-cPOCUS. This document provides (1) guidance on the purpose and rationale for both TNE and cPOCUS, (2) an overview of the components of a standard TNE and cPOCUS evaluation, (3) disease and/or clinical scenario-based indications for TNE, (4) training and competency-based evaluative requirements for both TNE and cPOCUS, and (5) components of quality assurance. The writing group would like to acknowledge the contributions of Dr. Regan Giesinger who sadly passed during the final revisions phase of these guidelines. Her contributions to the field of neonatal hemodynamics were immense.

Abstract
BACKGROUND Hyperglycemia during pregnancy can affect fetal heart in many ways, including causing cardiac malformation, leading to hypertrophic cardiomyopathy and cardiac dysfunction. Echocardiographic evaluation can assist identify alterations in heart structure, morphology and function, enabling prompt monitoring and management. However, according to earlier research, the cardiac alterations are modest in hyperglycemic mothers' fetuses, and might not be detectable using conventional methods and it is also unclear whether these changes are related to the metabolism of mothers. Fetal Heart Quantification (Fetal HQ) can assess ventricular geometry and function more sensitively and thoroughly, and identify sub-clinical cardiac dysfunction. The purpose of this study was to evaluate fetal heart by Fetal HQ in fetuses of hyperglycemic mothers who either had pre-gestational or gestational diabetes and to correlate them with maternal metabolic indices. METHODS The fetuses of 25 gestational age-matched control mothers, 48 women with gestational diabetes mellitus (GDM), and 11 women with diabetes mellitus (DM) were included in the prospective case-control research. Using fetal echocardiography and speckle tracking echocardiography (STE), the heart of the fetus was evaluated. Differences in the groups' anthropometric, metabolic, and cardiac parameters were examined. It was assessed whether maternal features, prenatal glucose, lipids, and maternal hemoglobin A1c (HbA1c) correlated with fetal cardiac parameters. RESULTS The LV EDV and ESV were significantly higher in the GDM group as compared to the DM group (p < 0.05). The GSI% was significantly lower in the GDM group compared with the control (p < 0.05). The LV SV and CO of the GDM group were both significantly higher compared with the DM group (p < 0.05). There was a significant decrease in RV FS for segments 1-7 in GDM fetuses compared to the control (p < 0.05) and for segments 5-10 compared to DM (p < 0.05). Fetal cardiac morphology and function indices correlate with maternal pregestational weight, BMI, early pregnancy fast glucose, lipids, and glycemic control levels. CONCLUSIONS Fetuses exposed to gestational diabetes have altered heart morphology and function that is linked to maternal metabolic parameters, which presents a special indication for performing geometry and function cardiac assessment. Fetal HQ can be employed to evaluate the fetal cardiac shape and function in fetuses exposed to gestational diabetes.

Abstract
BACKGROUND A diabetic intrauterine environment has been proposed as a potential etiological mechanism for in utero programming of cardiac disease, and is associated with impaired fetal cardiac function. We aimed to assess cardiac function in offspring of mothers with diabetes mellitus (ODM) and determine whether fetal cardiac abnormalities persist during follow-up. METHODS Longitudinal observational study to evaluate and compare myocardial function in 40 ODM to age-matched control offspring (CO). Myocardial deformation was measured using speckle-tracking echocardiography (STE). RESULTS Significant differences were detected in global longitudinal strain (-20.9 ± 3.1 vs. -23.6 ± 2.2%; p = 0.001), global circumferential strain (-24.4 ± 3.9 vs. -26.9 ± 2.7%; p = 0.017), average radial strain (29.0 ± 9.8 vs. 37.1 ± 7.2%; p = 0.003), average longitudinal systolic strain rate (-1.24 ± 0.25/s vs. -1.47 ± 0.30/s; p = 0.011) and average circumferential systolic strain rate (-1.56 ± 0.37/s vs. -1.84 ± 0.37/s; p = 0.013) in comparison to CO up to 2 years of follow-up. Minimal differences were observed within ODM over the 2-year period. CONCLUSION Impaired cardiac function in ODM persists during 2 years follow-up. Functional cardiac assessment might therefore be useful to detect these unfavorable changes, independent of screening for congenital heart disease or hypertrophic cardiomyopathy in this population. IMPACT We demonstrate persistence of subclinical myocardial deformation abnormalities in offspring of mothers with diabetes mellitus from fetal life to early childhood years. These results extend the cellular observations in basic and translational research of developmental programming into the clinical realm. Persistence of subclinical myocardial deformation abnormalities may shed light on the known incidence of early cardiovascular disease in offspring of mother with diabetes. Cardiac myocardial strain assessment can be useful to detect these abnormalities, independent of screening for congenital heart disease or hypertrophic cardiomyopathy in this population.

Abstract
The consistently high prevalence of cardiovascular disease (CVD) has urged the need for punctual and effective prevention. Extended research on this specific area has demonstrated the influence of fetal and neonatal periods on the risk of developing CVD in adulthood. Thus, the role of traditional and novel biological markers to the effective screening of CVD among the neonatal population is widely investigated. The objective of the present narrative review is to examine those neonatal biomarkers that may play a role in the development of CVD, to exhibit scientific data that appertain to their association with various perinatal conditions leading to CVD predisposition, and their potential role on prediction and prevention strategies. Multiple biomarkers, traditional and novel, have been mined across the studied literature. Adiposity, insulin resistance, altered lipid profile, inflammation, and endothelial dysfunction seem among the headliners of CVD. Even though various novel molecules have been studied, their clinical utility remains controversial. Therefore, it is quite important for the scientific community to find elements with strong predictive value and practical clinical use.

Abstract
Objective The aim was to demonstrate the prevalence of fetal myocardial hypertrophy (FMH) in diabetes mellitus (DM) pregnant women using spatio-temporal image correlation (STIC) M-mode. Material and Methods This prospective descriptive study was conducted at Bhumibol Adulyadej Hospital (BAH) Royal Thai Air Force between April and December 2022. Participants were singleton DM pregnant women with gestational age (GA) between 18 and 40 weeks who had antenatal care and delivery at BAH. DM screening was randomized blood sugar obtained from all participants. All participants underwent fetal heart exams by four-dimension ultrasound with STIC M-mode. Results One hundred and forty-five participants were recruited and classified as pregestational (PDM) and gestational DM (GDM) at 31 and 114 cases, respectively. The mean age of participants was 31.7 years old. Fasting blood sugar (FBS) of PDM was significantly higher than GDM (105.1 vs 87.0 mg%). GDMA2 had more elevated FBS than GDMA1 (p < 0.001). PDM had significantly greater FBS and two-hour postprandial blood sugar (2hr-PP) than GDM (105.1/87.0 and 151.5/117.9 mg%, respectively). FBS and 2hr-PP of GDMA2 were more than GDMA1 with statistical significance. Good glycemic control of GDM was significantly better than PDM. GDMA1 had better glycemic control than GDMA2 with statistical significance. Four-fifth (115/145) of participants had FMH. FMH and estimated fetal weight among PDM and GDM were comparable. Both good and poor glycemic control had similar FMH. Neonatal outcomes of FMH or non-FMH infants were similar. Conclusion The prevalence of FMH in diabetic pregnant women was 79.3%. Glycemic control had no correlation to FMH.

Maternal obesity in pregnancy and children’s cardiac function and structure: A systematic review and meta-analysis of evidence from human studies. PLoS One 2022; 17:e0275236.

Abstract
The prevalence of obesity is increasing worldwide. Experimental animal studies demonstrate that maternal obesity during pregnancy directly affects cardiac structure and function in their offspring, which could contribute to their increased cardiovascular disease (CVD) risk. Currently, a systematic overview of the available evidence regarding maternal obesity and alterations in cardiac structure and function in human offspring is lacking. We systematically searched the electronic databases Embase, MEDLINE and NARCIS from inception to June 29, 2022 including human studies comparing cardiac structure and function from fetal life onwards in offspring of women with and without obesity. The review protocol was registered with PROSPERO International Prospective Register of Systematic Reviews (identifier: CRD42019125071). Risk of bias was assessed using a modified Newcastle-Ottawa scale. Results were expressed using standardized mean differences (SMD). The search yielded 1589 unique publications, of which thirteen articles were included. Compared to offspring of women without obesity, fetuses of women with obesity had lower left ventricular strain, indicative of reduced systolic function, that persisted in infancy (SMD -2.4, 95% confidence interval (CI) -4.4 standard deviation (SD) to -0.4 SD during fetal life and SMD -1.0, 95% CI -1.6 SD to -0.3 SD in infancy). Furthermore, infants born to women with obesity had a thicker interventricular septum (SMD 0.6 SD, 95% CI 0.0 to 1.2 SD) than children born to women without obesity. In conclusion, cardiac structure and function differs between fetuses and children of women with and without obesity. Some of these differences were present in fetal life, persisted in childhood and are consistent with increased CVD risk. Long-term follow-up research is warranted, as studies in offspring of older age are lacking.

Abstract
AIMS No previous research provided a complete biventricular and multidirectional left ventricular (LV) functional assessment by two-dimensional (2D) speckle tracking echocardiography (STE) in infants of gestational diabetic mothers (IGDM) METHODS: A total of 30 consecutive IGDM and 30 infants of healthy mothers were examined between March 2021 and July 2021. Both groups of infants underwent evaluation by neonatologist and 2D transthoracic echocardiography (TTE) implemented with 2D-STE quantification of LV-global longitudinal strain (GLS), LV-global circumferential strain (GCS), LV-global radial strain (GRS) and right ventricular (RV)-GLS, within 3 days of life and at 40 days after birth. Predictors of persistent subclinical myocardial dysfunction, defined as a LVGLS less negative than -20% at 40-day follow-up, in IGDM population, were determined. RESULTS At 2.2 ± 1.3 days after birth, LV-GLS (- 17.2 ± 1.9 vs. - 23.9 ± 3.8%), LV-GCS (- 17.9 ± 2.7 vs. - 27.3 ± 3.4%), LV-GRS (25.6 ± 3.4 vs. 35.8 ± 3.6%) and RV-GLS (- 17.6 ± 3.6 vs. - 22.6 ± 3.8%) were significantly impaired in IGDM than controls (all p < 0.001). At 36.8 ± 5.2 days of life, LV-GLS was still impaired (less negative than -20%) in 26.6% of IGDM. Maternal third trimester body mass index (BMI) (OR 1.89, 95%CI 1.05-3.39) and third trimester glycosylated hemoglobin (HbA1C) (OR 1.59, 95%CI 1.08-2.19) were independently associated with persistent LV-GLS impairment in IGDM. Maternal BMI ≥ 30 Kg/m2 and HbA1C ≥ 38 mmol/mol showed the maximum of sensitivity and specificity for predicting persistent subclinical myocardial dysfunction in IGDM at 40 days of life. CONCLUSIONS IGDM have diffuse pattern of myocardial dysfunction during perinatal period. This dysfunction may be persistent up to 40 days of life in infants of GDM women with obesity and uncontrolled diabetes.

Abstract
BACKGROUND Gestational diabetes mellitus (GDM) is a complication of pregnancy strongly associated with an increased risk of structural fetal abnormalities. As the fetal heart grows quickly during the late-term pregnancy period, it is important to understand fetal heart growth before birth. This study explored how GDM affects fetal heart growth by evaluating basic echocardiography indicators during late pregnancy. METHODS This prospective, longitudinal study included 63 GDM patients (GDM group) and 67 healthy pregnant women (control group). All subjects underwent fetal echocardiography scans at gestational weeks 28-32, 32-36, and 36-40. Twelve echocardiographic indicators were assessed at each observation and analyzed by using a mixed model. RESULTS The left atrial diameter (LA) and left ventricular end-diastolic diameter (LV) similarly increased from the first to the third observation. The right ventricular end-diastolic diameter (RV) was significantly different between the groups, and a group × time interaction was detected. The tricuspid annular peak systolic velocity (s') increased more rapidly in the GDM than the control group during the first to second observations, and the group × time interaction was significant. The increase in the tricuspid annular plane systolic excursion (TAPSE) of the GDM group was "slow-fast", while that of the control group was "fast-slow", during three observations. After adjusting covariates, the group difference and interaction effect of TAPSE and RV remained significant. CONCLUSIONS The differences in fetal right heart indicators between the GDM and control groups suggest that GDM may affect the structure and functional growth of the fetal right heart during late-term pregnancy.

Abstract
OBJECTIVE This study aimed to determine the feasibility and effectiveness of Diabetes Group Prenatal Care to increase patient engagement in diabetes self-care activities. STUDY DESIGN A pilot randomized controlled trial was conducted at two sites. Inclusion criteria were English or Spanish speaking, type 2 or gestational diabetes, 22 to 34 weeks of gestational age at first study visit, ability to attend group care at specified times, and willingness to be randomized. Exclusion criteria included type 1 diabetes, multiple gestation, major fetal anomaly, serious medical comorbidity, and serious psychiatric illness. Women were randomized to Diabetes Group Prenatal Care or individual prenatal care. The primary outcome was completion of diabetes self-care activities, including diet, exercise, blood sugar testing, and medication adherence. Secondary outcomes included antenatal care characteristics, and maternal, neonatal, and diabetes management outcomes. Analysis followed the intention-to-treat principle. RESULTS Of 159 eligible women, 84 (53%) consented to participate in the study and were randomized to group (n = 42) or individual (n = 42) prenatal care. Demographic characteristics were similar between study arms. Completion of diabetes self-care activities was similar overall, but women in group care ate the recommended amount of fruits and vegetables on more days per week (5.1 days/week ± 2.0 standard deviation [SD] in group care vs. 3.4 days ± 2.6 SD in individual care; p < 0.01) and gained less weight per week during the study period (0.2 lbs/week [interquartile range: 0-0.7] vs. 0.5 lbs/week [interquartile range: 0.2-0.9]; p = 0.03) than women in individual care. Women with gestational diabetes randomized to group care were 3.5 times more likely to have postpartum glucose tolerance testing than those in individual care (70 vs. 21%; relative risk: 3.5; 95% confidence interval: 1.4-8.8). Other maternal, neonatal, and pregnancy outcomes were similar between study arms. CONCLUSION Diabetes group care is feasible and shows promise for decreasing gestational weight gain, improving diet, and increasing postpartum diabetes testing among women with pregnancies complicated by diabetes. KEY POINTS · Women with gestational diabetes in group care were 3.5 times more likely to return for postpartum glucose tolerance testing.. · Women with gestational diabetes in group care had less gestational weight gain during the study period.. · Diabetes Group Prenatal Care is a promising intervention to improve outcomes for women with diabetes in pregnancy..

Abstract
INTRODUCTION Offspring of diabetic mothers have five times higher risk of cardiovascular abnormalities than in normal pregnancies. These cardiac anomalies involve fetal cardiac morphological and functional changes. Here, we investigate subclinical cardiovascular abnormalities, including structural and functional changes among infants of diabetic mothers. MATERIAL AND METHODS A prospective cohort study was carried out from March 2017 to September 2020 at a South Indian tertiary care center. One hundred ninety-eight newborns delivered from non-diabetic mothers, well-controlled diabetic mothers (WCDM), and poorly controlled diabetic mothers (PCDM) were studied. Neonates and infantile echocardiographic imaging were performed at the first week of life, at 6-weeks, and 6-months of life. Cardiac structure and function were assessed using 2D, M-mode, Conventional Doppler, and Tissue Doppler imaging. RESULTS Out of the total (198) infants, 66 (33.3%) were from the non-diabetic (control) mothers, 60 (30.3%) from the WCDM, and 72 (36.4%) were from the PCDM groups. In both WCDM and PCDM groups, the mean gestational ages at birth were shorter than the control group (37.19 ± 0.82, 36.02 ± 2.15, and 37.91 ± 1.33 weeks respectively). There was a high incidence of neonatal hypoglycemia (p-value <0.001), NICU stay >7 days (p-value <0.018), and persistent fetal transitional cardiac shunt (p-value <0.03) among poorly controlled DM group in comparison to others. Tissue deformation imaging showed a significant reduction in left ventricular global strain and strain rate in the neonatal heart from poorly controlled diabetic mothers. Myocardial wall thickness among neonates of diabetic mothers was higher compared to controls. LV TEI was higher in PCDM groups in comparison with WCDM and control groups; (0.59 ± 0.11, 0.46 ± 0.35, and 0.37 ± 0.12 respectively, p-value =0.01). Similarly, RV TEI was high in the PCDM (0.56 ± 0.09) group compared to the WCDM group (0.33 ± 0.12) and control group (0.28 ± 0.10). CONCLUSIONS Infants of diabetic mothers are at higher risk of developing cardiac abnormalities, including structural and functional defects. The highest increase in interventricular septal thickening found in poorly controlled diabetic mothers' neonates will disrupt both ventricles' functions, followed by WCDM and the control group.

Effect of maternal diabetes on fetal heart function on echocardiography: systematic review and meta-analysis. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2021; 57:539-550. [PMID: 32730637 PMCID: PMC8048940 DOI: 10.1002/uog.22163] [Citation(s) in RCA: 43] [Impact Index Per Article: 14.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/20/2020] [Revised: 06/20/2020] [Accepted: 07/22/2020] [Indexed: 05/22/2023]
Abstract
OBJECTIVE Maternal diabetes in pregnancy is associated with structural anomalies of the fetal heart, as well as hypertrophy and functional impairment. This systematic review and meta-analysis aimed to estimate the effect of maternal diabetes on fetal cardiac function as measured by prenatal echocardiography. METHODS We performed a search of the EMBASE, PubMed and The Cochrane Library databases, from inception to 4 July 2019, for studies evaluating fetal cardiac function using echocardiography in pregnancies affected by diabetes compared with uncomplicated pregnancies. Outcome measures were cardiac hypertrophy and diastolic, systolic and overall cardiac function as assessed by various ultrasound parameters. The quality of the studies was assessed using the Newcastle-Ottawa Scale. Data on interventricular septal (IVS) thickness, myocardial performance index (MPI) and E/A ratio were pooled for the meta-analysis using random-effects models. For pregnancies with diabetes, results were reported overall and according to whether diabetes was pregestational (PDM) or gestational (GDM). Results were also stratified according to the trimester in which fetal cardiac assessment was performed. RESULTS Thirty-nine studies were included, comprising data for 2276 controls and 1925 women with pregnancy affected by diabetes mellitus (DM). Of these, 1120 had GDM, 671 had PDM and in 134 cases diabetes type was not specified. Fetal cardiac hypertrophy was more prevalent in diabetic pregnancies than in non-diabetic controls in 21/26 studies, and impaired diastolic function was observed in diabetic pregnancies in 22/28 studies. The association between DM and systolic function was inconsistent, with 10/25 studies reporting no difference between cases and controls, although more recent studies measuring cardiac deformation, i.e. strain, did show decreased systolic function in diabetic pregnancies. Of the studies measuring overall fetal cardiac function, the majority (14/21) found significant impairment in diabetic pregnancies. Results were similar when stratified according to GDM or PDM. These effects were already present in the first trimester, but were most profound in the third trimester. Meta-analysis of studies performed in the third trimester showed, compared with controls, increased IVS thickness in both PDM (mean difference, 0.75 mm (95% CI, 0.56-0.94 mm)) and GDM (mean difference, 0.65 mm (95% CI, 0.39-0.91 mm)) pregnancies, decreased E/A ratio in PDM pregnancies (mean difference, -0.09 (95% CI, -0.15 to -0.03)), no difference in E/A ratio in GDM pregnancies (mean difference, -0.01 (95% CI, -0.02 to 0.01)) and no difference in MPI in either PDM (mean difference, 0.04 (95% CI, -0.01 to 0.09)) or GDM (mean difference, 0.03 (95% CI, -0.01 to 0.06)) pregnancies. CONCLUSIONS The findings of this review show that maternal diabetes is associated with fetal cardiac hypertrophy, diastolic dysfunction and overall impaired myocardial performance on prenatal ultrasound, irrespective of whether diabetes is pregestational or gestational. Further studies are needed to demonstrate the relationship with long-term outcomes. © 2020 The Authors.

Abstract
INTRODUCTION There is a strong association between gestational obesity and fetal cardiac dysfunction, while the exact mechanisms remain largely unknown. The purpose of this study was to investigate the role of exosomes from maternal visceral adipose tissue in abnormal embryonic development in obese pregnancy. METHODS Female C57BL/6J obese mice were induced by a high-fat diet (containing 60% fat). Fetal cardiac function and morphology were examined by echocardiography and histology. The placenta was extracted for histological examination. miRNA expression in exosomes from the visceral adipose tissue was profiled by RNA-seq. Gene expression of inflammatory factors was analyzed by qPCR. RESULTS In the obese pregnant mice, there were obvious inflammation and lipid droplets in the placenta. And the fetal cardiac function in obese pregnancy was also compromised. Moreover, injection of the visceral adipose tissue exosomes from the obese mice significantly decreased the fetal cardiac function in the normal lean pregnant mice. Mechanistically, the decreased expression of miR-19b might be responsible for the enhanced inflammation in the placenta. DISCUSSION Exosomes derived from visceral adipose tissue in obese mice contribute to fetal heart dysfunction, at least partially via affecting the function of the placenta.

Abstract
Background In several developing industrial countries, the incidence of obesity among populations is spreading quickly and dramatically; also, the frequency of maternal obesity is in continuous elevation, which represents a considerable public health problem. Maternal hyperglycemia is a common gestational risk factor for the fetus. Several studies proposed that maternal DM and obesity lead to intrauterine impacts which induce changes in the fetal myocardium, and the pre-pregnancy obesity and diabetes are accompanied with development of cardiovascular alterations in the offspring and subsequent pathological changes in their early life. The aim of this study is to assess the cardiac function in fetuses of obese pregnant women (FOW) and fetuses of diabetic women (FDW) in comparison with fetuses of normal pregnant women (FNW) using tissue Doppler imaging. Results There was impairment in systolic and diastolic cardiac function in both fetuses of obese and diabetic women with decreased global longitudinal strain tissue Doppler velocities at 30 weeks of gestation compared to fetuses of normal women. Conclusion Imaging of the fetus of pregnant women by Echo Doppler at about 30 weeks of gestations showed a reduced cardiac function of fetuses of obese and diabetic women matched with fetuses of normal BMI women. Our finding proposed that early subclinical alterations in the fetal cardiac output can arise from maternal obesity alone. This explains the predilection of children of obese mothers at advanced ages to cardiovascular disorder.

Abstract
INTRODUCTION Prematurity impacts myocardial development and may determine long-term outcomes. The objective of this study was to test the hypothesis that preterm neonates develop right ventricle dysfunction and adaptive remodelling by 32 weeks post-menstrual age that persists through 1 year corrected age. MATERIALS AND METHODS A subset of 80 preterm infants (born <29 weeks) was selected retrospectively from a prospectively enrolled cohort and measures of right ventricle systolic function and morphology by two-dimensional echocardiography were assessed at 32 weeks post-menstrual age and at 1 year of corrected age. Comparisons were made to 50 term infants at 1 month and 1 year of age. Sub-analyses were performed in preterm-born infants with bronchopulmonary dysplasia and/or pulmonary hypertension. RESULT In both term and preterm infants, right ventricle function and morphology increased over the first year (p < 0.01). The magnitudes of right ventricle function measures were lower in preterm-born infants at each time period (p < 0.01 for all) and right ventricle morphology indices were wider in all preterm infants by 1 year corrected age, irrespective of lung disease. Measures of a) right ventricle function were further decreased and b) morphology increased through 1 year in preterm infants with bronchopulmonary dysplasia and/or pulmonary hypertension (p < 0.01). CONCLUSION Preterm infants exhibit abnormal right ventricle performance with remodelling at 32 weeks post-menstrual age that persists through 1 year corrected age, suggesting a less developed intrinsic myocardial function response following preterm birth. The development of bronchopulmonary dysplasia and pulmonary hypertension leave a further negative impact on right ventricle mechanics over the first year of age.

Normalisation of circulating adiponectin levels in obese pregnant mice prevents cardiac dysfunction in adult offspring. Int J Obes (Lond) 2019; 44:488-499. [PMID: 31076636 DOI: 10.1038/s41366-019-0374-4] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2018] [Revised: 03/06/2019] [Accepted: 03/26/2019] [Indexed: 01/12/2023]
Abstract
BACKGROUND/OBJECTIVES Adiponectin concentrations are low in obese pregnant women. Restoring normal adiponectin concentrations by infusion in obese pregnant mice prevents placental dysfunction, foetal overgrowth and metabolic syndrome in the offspring. We hypothesised that normalising maternal adiponectin in obese late pregnant dams prevents cardiac dysfunction in the adult offspring. SUBJECTS/METHODS Pregnant female mice with diet-induced obesity were infused with adiponectin (0.62 μg g-1 day-1, n = 24) or saline (n = 22) over days 14.5-18.5 of pregnancy (term = day 19.5). Control dams ate standard chow and received saline (n = 22). Offspring were studied at 3 and 6 months of age. RESULTS Maternal obesity impaired ventricular diastolic function, increased cardiomyocyte cross-sectional area and upregulated cardiac brain natriuretic peptide (Nppb) and α-skeletal actin (Acta1) gene expression in adult male offspring, compared to control offspring. In adult female offspring, maternal obesity increased Nppb expression, decreased end-diastolic volume and caused age-dependent diastolic dysfunction but not cardiomyocyte hypertrophy. Maternal obesity also activated cardiac Akt and mechanistic target of rapamycin (mTOR) signalling in male, but not in female, offspring and inhibited cardiac extracellular signal-regulated kinase 1/2 (ERK1/2) in both sexes. Normalising maternal circulating adiponectin concentrations by infusing obese dams with adiponectin prevented offspring diastolic dysfunction and ventricular dilation and normalised cardiac Akt-mTOR signalling irrespective of sex. Maternal adiponectin infusion also reduced cardiac Nppb expression and increased ERK1/2 signalling in offspring of obese dams. Adiponectin infusion did not prevent cardiomyocyte hypertrophy but reduced ventricular wall thickness in male offspring and increased collagen content in female offspring of obese dams, compared to controls. CONCLUSIONS Low maternal adiponectin levels in obese mice in late pregnancy are mechanistically linked to in utero programming of cardiac dysfunction in their offspring. Interventions enhancing endogenous adiponectin secretion or signalling in obese pregnant women could prevent the development of cardiac dysfunction in their children.

Abstract
OBJECTIVE The objective of this study is to test whether myocardial performance is impaired over the first week of age in infants with Down syndrome (DS) without congenital heart disease (CHD). STUDY DESIGN A prospective cohort study of 20 infants with DS without CHD and 17 healthy term infants comparing echocardiographic measures of left (LV) and right (RV) ventricular function and pulmonary hypertension (PH) on days 1, 2, and 5-7. RESULTS Indices of PH were higher in the DS group over the study period. Infants with DS had larger RV and smaller LV dimensions. Fractional area change and RV longitudinal strain values were lower in the DS group. LV shear strain values were lower in infants with DS driven by a lack of basal rotation. CONCLUSION Infants with DS without CHD and echocardiographic evidence of PH during the early neonatal period demonstrate reduced RV systolic function with impaired LV rotational mechanics, reflective of the ventricular interdependence.

Abstract
AIM To test the hypothesis that right ventricular (RV) function has age-specific patterns of development, we tracked the evolution of RV strain mechanics by 2D-speckle tracking echocardiography (2DSTE) in healthy subjects from mid-gestation through one year of age. METHODS We conducted a prospective longitudinal echocardiography study in 50 healthy subjects at five time periods across gestation (16-20 weeks, 21-25 weeks, 26-30 weeks, 31-35 weeks, and 36-40 weeks) and four time periods following delivery (1 week, 1 month, 6 months, and 1 year of age). We characterized RV function by measuring RV global and free wall longitudinal strain and systolic strain rate, and segmental longitudinal strain at the apical-, mid-, and basal- ventricular levels of the free wall. Possible associations of gestational age, postnatal age, estimated fetal weight, body surface area, gender, and heart rate on strain were investigated. RESULTS The magnitudes of RV global and free wall longitudinal strain and global strain rate were decreased throughout gestation (p < 0.05 for all). Following birth, the magnitudes of all measures increased from one week through one year (p < 0.001 for all). RV segmental longitudinal strain maintained a base-to-apex gradient (highest-to-lowest) from mid-gestation through one year (p < 0.001). There was no significant difference in strain patterns based on gender or hear rate. CONCLUSION The maturational patterns of RV strain are gestational- and postnatal age- specific. With accepted physiological maturation patterns in healthy subjects, these myocardial deformation parameters can provide a valid basis that allows comparison between health and disease.

Abstract
Background The prevalence of maternal obesity is rising. Pre-pregnancy obesity is associated with later cardiovascular disease in the child and the underlying pathogenesis begins in early life. Therefore, pregnancy and infancy are key periods for potential intervention. The aim of this study was to study the cardiac function in newborns of obese women compared to newborns of normal-weight women, and to determine if exercise intervention during pregnancy could have an effect on cardiac function of newborns to obese women. Material and methods Fifty-five pregnant women, 51 obese (BMI ≥ 30 kg/m2) and four overweight (BMI 28–30 kg/m2), were randomized to an exercise training group (n = 27) or a control group (standard maternity care, n = 28). From gestational week 14 until delivery participants in the intervention group were offered supervised training sessions three times weekly. In addition, they were told to exercise at home once weekly. All newborns had an echocardiogram performed 1–3 days and 6–8 weeks after delivery. The results were compared with newborns of normal weight women (n = 20, standard maternity care). Results Newborns of obese women had an impaired systolic and diastolic cardiac function with reduced global strain, strain rate, tissue Doppler velocities and a thicker intraventricular septum at birth and after 6–8 weeks after delivery compared to newborns of normal weight women. Exercise had no statistically significant effect on either of the cardiac function parameters. The mean (± standard deviation) adherence to the exercise protocol was 1.3 ± 0.8 sessions per week for supervised training and 0.8 ± 0.7 sessions per week for home-based exercise training. Conclusions Newborns of obese women had reduced cardiac function and thicker intraventricular septum compared to newborns of normal weight women. Exercise training during pregnancy had no significant effect, potentially due to a low number of subjects and low adherence to the exercise protocol. Trial registration ClinicalTrials.gov NCT01243554.
