Pregnancy Complications, Cardiovascular Risk Factors, and Future Heart Disease

A risk prediction model of gestational diabetes mellitus based on traditional and genetic factors

BACKGROUND

Gestational diabetes mellitus (GDM) is a prevalent pregnancy complication during pregnancy. We aimed to evaluate a risk prediction model of GDM based on traditional and genetic factors.

METHODS

A total of 2744 eligible pregnant women were included. Face-to-face questionnaire surveys were conducted to gather general data. Serum test results were collected from the laboratory information system. Independent risk factors for GDM were identified using univariate and multivariate logistic regression analyses. A GDM risk prediction model was constructed and evaluated with the Hosmer-Lemeshow goodness-of-fit test, goodness-of-fit calibration plot, receiver operating characteristic curve and area under the curve.

RESULTS

Among traditional factors, age ≥30 years, family history, GDM history, impaired glucose tolerance history, systolic blood pressure ≥116.22 mmHg, diastolic blood pressure ≥74.52 mmHg, fasting plasma glucose ≥5.0 mmol/L, 1-hour postprandial blood glucose ≥8.8 mmol/L, 2-h postprandial blood glucose ≥7.9 mmol/L, total cholesterol ≥4.50 mmol/L, low-density lipoprotein ≥2.09 mmol/L and insulin ≥11.5 mIU/L were independent risk factors for GDM. Among genetic factors, 11 single nucleotide polymorphisms (SNPs) (rs2779116, rs5215, rs11605924, rs7072268, rs7172432, rs10811661, rs2191349, rs10830963, rs174550, rs13266634 and rs11071657) were identified as potential predictors of the risk of postpartum DM among women with GDM history, collectively accounting for 3.6% of the genetic risk.

CONCLUSIONS

Both genetic and traditional factors contribute to the risk of GDM in women, operating through diverse mechanisms. Strengthening the risk prediction of SNPs for postpartum DM among women with GDM history is crucial for maternal and child health protection.

Effect of Comprehensive Educational Program on Preeclamptic Women's Risk Perception of Cardiovascular Disease, Self-Efficacy, and Adherence to Healthy Lifestyle Behaviors

PURPOSE

To evaluate the effect of a comprehensive educational program on preeclamptic women's knowledge, risk perception of cardiovascular disease, self-efficacy, and adherence to healthy lifestyle behaviors.

PATIENTS AND METHODS

This study employed a pretest-posttest design. One hundred and two women who previously had preeclampsia were enrolled from July 2022 to December 2022 from outpatient obstetrics, gynecology, and family planning clinics. The primary and secondary outcomes were measured at baseline, after eight weeks, and after three months of the educational intervention. The data were analyzed using SPSS version 23, descriptive and inferential statistics, specifically the Chi-square test, independent t-tests, and repeated measures ANOVA.

RESULTS

A statistically significant difference was found between the two groups immediately post-intervention and the three-month follow-up, with a significant improvement among the intervention group than control group regarding cardiovascular disease knowledge (p < 0.001), risk perception (p < 0.001), self-efficacy (p < 0.001), and healthy lifestyle behaviors (p < 0.001). There was a statistically significant interaction between group and time regarding total cardiovascular disease risk perception (F = 203.67, p < 0.001, η2 = 0.673), self-efficacy (F = 70.06, p < 0.001, η2 = 0.405), and adherence to healthy lifestyle behaviors (F = 145.08, p < 0.001, η2 = 0.597).

CONCLUSION

This study concluded that the comprehensive educational program had a positive effect on improving preeclamptic women's knowledge and risk perception of CVD, self-efficacy, and adherence to healthy lifestyle behaviors following preeclampsia.

Docosahexaenoic Acid and Pregnancy: A Systematic Review and Meta-Analysis of the Association with Improved Maternal and Fetal Health

This study aimed to investigate the effects of prenatal docosahexaenoic acid (DHA) supplementation on pregnancy outcomes through a systematic review and meta-analysis. We hypothesized that prenatal DHA intake through supplements will improve pregnancy outcomes. Detailed literature search was performed using online databases such as PubMed, EMBASE, and Google Scholar till November 2022, to identify the randomized controlled trials (RCT) with maternal intake of DHA supplementation during the latter half of pregnancy compared to the placebo/control. Based on the inclusion and exclusion criteria, nine RCTs involving 5710 subjects were included. This meta-analysis showed that DHA supplementation (450-800 mg/day) was associated with a significantly higher birth weight of infants (Inverse variance [IV]: 101.71 [57.36-146.06] at 95% CI, P = .00001, I2 = 0%), and fewer low birth weights (LBWs) (Mantel-Haenszel [M-H]: 0.53 [0.33-0.86] at 95% CI, P = .01, I2 = 72%), with lesser but statistically insignificant pre-term births (PTB) (M-H: -0.02 [-0.04 to 0.00] at 95% CI, P = .07, I2 = 0%) compared to the placebo. However, the DHA supplementation has no effect on gestational length (IV: -2.26 [-9.64 to 5.12] at 95% CI, P = .55, I2 = 100%) compared to the placebo. In conclusion, the outcomes of this meta-analysis showed that prenatal DHA supplementation (450-800 mg/day) may reduce the risk of preterm births and increase infant birth weight.

Association between pre- and postnatal exposure to endocrine-disrupting chemicals and birth and neurodevelopmental outcomes: an extensive review

Endocrine-disrupting chemicals (EDCs) are natural or synthetic chemicals that mimic, block, or interfere with the hormones in the body. The most common and well- studied EDCs are bisphenol A, phthalates, and persistent organic pollutants including polychlorinated biphenyls, polybrominated diphenyl ethers, per- and polyfluoroalkyl substances, other brominated flame retardants, organochlorine pesticides, dioxins, and furans. Starting in embryonic life, humans are constantly exposed to EDCs through air, diet, skin, and water. Fetuses and newborns undergo crucial developmental processes that allow adaptation to the environment throughout life. As developing organisms, they are extremely sensitive to low doses of EDCs. Many EDCs can cross the placental barrier and reach the developing fetal organs. In addition, newborns can be exposed to EDCs through breastfeeding or formula feeding. Pre- and postnatal exposure to EDCs may increase the risk of childhood diseases by disrupting the hormone-mediated processes critical for growth and development during gestation and infancy. This review discusses evidence of the relationship between pre- and postnatal exposure to several EDCs, childbirth, and neurodevelopmental outcomes. Available evidence suggests that pre- and postnatal exposure to certain EDCs causes fetal growth restriction, preterm birth, low birth weight, and neurodevelopmental problems through various mechanisms of action. Given the adverse effects of EDCs on child development, further studies are required to clarify the overall associations.

Cholesterol-lowering effects of rhubarb free anthraquinones and their mechanism of action

Rhubarb free anthraquinones (RhA) have significant lipid-regulating activity. However, whether RhA monomers have a role in lipid-regulating and their mechanism of action remains unclear. Based on the cholesterol accumulated HepG2 cell model, the cholesterol-regulating effect of RhA monomers and their combinations was investigated. The expression of sterol-regulatory element binding protein 2 (SREBP2), 3-hydroxy-3-methyl glutaryl coenzyme A reductase (HMGCR) and squalene monooxygenase (SQLE) of the model cells was analyzed to preliminarily explore the mechanism of action. After that, the liposomes of each active RhA monomer were separately prepared with the same lipid materials and the same preparation method so that each monomer has similar or equal bioavailability after oral administration to rats. Finally, the hypercholesterolemic rat model was established, and the effect of active RhA monomers loaded liposomes as well as their combinations on cholesterol-regulating was investigated and their mechanism of action was analyzed. The results showed that aloe-emodin, rhein and emodin were the main cholesterol-regulating components of RhA, and the combination of rhein and emodin showed significant cholesterol-lowering effect, which may be related to the expression of SREBP2, HMGCR and SQLE in the rat liver.

Child rearing or childbearing? Risk of cardiovascular diseases associated to parity and number of children

BACKGROUND

An increased risk of cardiovascular diseases (CVD) has been associated with women's parity, but whether or not this association reflects a direct pregnancy effect, or exposure to factors related to childrearing, still appears unclear. We assessed the CVD risk associated with number of children separately by gender and tested effect modification by socioeconomic position (SEP) and employment status, in order to elucidate the possible mechanisms underlying this association.

METHODS

The study population was composed of 20,904 men and 25,246 women who were interviewed in one of two National Health Surveys conducted in 2000 and 2005 in Italy. These subjects were followed for CVD incidence up to 2014 through record-linkage with national archives of mortality and hospitalisations. CVD risk was estimated by Cox regression models that were adjusted for socio-demographics, perceived health, lifestyles, biological CVD risk factors and for other potential confounders.

RESULTS

CVD incidence was significantly increased among men with 3 or more children (HR = 1.26, 95% CI: 1.02-1.56) and among women with 2 and with 3 or more children (HR = 1.42, 95% CI: 1.10-1.83; and HR = 1.39, 95% CI: 1.03-1.87, respectively) compared to subjects without children and no significant gender differences were observed. Subjects with lower SEP displayed stronger associations with parity and a higher number of children for both genders; by contrast, no modifying effect of employment status was observed.

CONCLUSIONS

Taken together, the significant association between higher parity and CVD risk in both genders, and the higher risk of CVD associated with higher parity among lower SEP parents, suggests that childrearing has a potential effect on the development of CVD that is more pronounced among disadvantaged families, although a concurrent effect of childbearing cannot be completely excluded.

Culturally Tailored Strategies for Prenatal Physical Activity for South Asian Women: A Scoping Review

Low levels of physical activity (PA) are reported in South Asian pregnant women. This scoping review summarizes culturally tailored strategies in prenatal PA studies for South Asian women and identifies barriers and facilitators. A search strategy was developed with the keywords "Physical Activity" AND Pregnant AND "South Asian" and was carried out on Medline, SportDiscus, EMBASE, Web of Science and Proquest Theses and Dissertations. Primary research studies were included. Forty-six studies were included of which 40 were from South Asian countries. No interventions were identified outside of South Asian countries. Offering material in different languages was the most common tailoring strategy. Reported barriers were possible social norms favouring inactivity, lack of awareness on safe exercises, and physical symptoms (e.g., fatigue). Facilitators included social support and relief from physical symptoms. Future PA interventions for South Asian pregnant women should account for population-specific barriers and facilitators to increase PA initiation and maintenance.

Cardiovascular Risk in Pediatrics: A Dynamic Process during the First 1000 Days of Life

The early childhood period, encompassing prenatal and early stages, assumes a pivotal role in shaping cardiovascular risk factors. We conducted a narrative review, presenting a non-systematic summation and analysis of the available literature, focusing on cardiovascular risk from prenatal development to the first 1000 days of life. Elements such as maternal health, genetic predisposition, inadequate fetal nutrition, and rapid postnatal growth contribute to this risk. Specifically, maternal obesity and antibiotic use during pregnancy can influence transgenerational risk factors. Conditions at birth, such as fetal growth restriction and low birth weight, set the stage for potential cardiovascular challenges. To consider cardiovascular risk in early childhood as a dynamic process is useful when adopting a personalized prevention for future healthcare and providing recommendations for management throughout their journey from infancy to early adulthood. A comprehensive approach is paramount in addressing early childhood cardiovascular risks. By targeting critical periods and implementing preventive strategies, healthcare professionals and policymakers can pave the way for improved cardiovascular outcomes. Investing in children's health during their early years holds the key to alleviating the burden of cardiovascular diseases for future generations.

A Four-Dimensional Volumetric Quantification of the Left Ventricle in Healthy Pregnant Women in the Third Trimester

BACKGROUND

Hemodynamic load and heart structural remodeling rise during pregnancy because these changes are physiologically necessary. Adaptations in the mother's circulatory system may either initiate or aggravate the development of cardiovascular disease in the offspring. If the body is unable to adjust to these changes, it may develop heart conditions like cardiomyopathy. There is a lack of third-trimester echocardiographic data on left ventricular (LV) volume and function in healthy Iraqi women. To understand the cardiac alterations that occur during normal pregnancy, a precise tool that evaluates cardiac function is needed. In that regard, the four-dimensional echocardiography (4DE) technique has markedly improved the quality and accuracy of assessing the size and function of the left ventricle.

AIM

The present study aimed to assess LV volume and function in the third trimester of a healthy pregnancy using 4DE and to compare the results of LV assessment using 4DE with those of LV assessment using conventional two-dimensional (2D) echocardiography.

METHODS

The study was conducted on 75 healthy pregnant women (the case group) and 75 non-pregnant women (the control group). The participants attended Al-Fortat Teaching Hospital from April 1, 2022, to May 30, 2023, and had 2D and 4D echocardiographic studies performed on them.

RESULTS

The LV end-diastolic volume (EDV), end-systolic volume (ESV), and cardiac output (CO) were significantly increased in the case group compared to the control group (90.87 ± 18.03 ml vs. 62.64 ± 14.11 ml, P<0.001; 35.59 ± 6.52 ml vs. 22.42 ± 5.82 ml, P<0.001; and 4.87 ± 1.27 vs. 3.35 ± 0.87 L/m, P<0.001, respectively). In contrast, the LV ejection fraction (LVEF) was significantly decreased in the pregnant group compared to the control group (60.37 ± 5.42 % vs. 64.04 ± 4.99 %, P<0.01). Additionally, the study showed significant differences in EDV, ESV, ejection fraction (EF%), and CO (P<0.001) between 2D and 4D echocardiography, according to the Bland Altman test.

CONCLUSION

In healthy pregnant women in their third trimester, there is an increase in the indicators of preload (ventricular volume and CO) and a decrease in EF%. The 4DE provides detailed images and information about cardiac volumes and function, allowing for the early detection of any potential problems that may arise during pregnancy and thus improving the health outcomes of both the mother and the developing fetus.

Hypertensive Disorders of Pregnancy: Assessing the Significance of Lp(a) and ApoB Concentrations in a Romanian Cohort

Background: This research delves into the association between altered lipid profiles and hypertensive disorders of pregnancy (HDP), shedding light on cardiovascular implications in maternal health. Methods: A cohort of 83 pregnant women was studied, with 48.19% diagnosed with HDP. This investigation primarily focused on Apolipoprotein B (ApoB) and Lipoprotein(a) (Lp(a)) as indicators of cardiovascular health. A comparative examination was conducted to determine discrepancies in the ApoB and Lp(a) levels between standard pregnancies and those presenting with HDP. Results: Significant elevations in ApoB (p value = 0.0486) and Lp(a) (p value < 0.0001) levels were observed in pregnant women with HDP compared to their counterparts with typical pregnancies. The pronounced link between heightened ApoB and Lp(a) concentrations and HDP persisted, even considering pregnancy's distinct physiological conditions. Conclusions: Our research accentuates the crucial role of early detection and specialized handling of cardiovascular risks in expectant mothers, especially those predisposed to HDP. The study indicates ApoB and Lp(a)'s potential as reliable markers for gauging cardiovascular threats during gestation. Furthermore, our findings suggest an integrative care approach and guidance for pregnant women, aspiring to enhance cardiovascular health in the postpartum phase.

Application effect of gastrointestinal bundle nursing on the protection of gastrointestinal function in patients with gastric cancer

Evidence-based nursing practice was used to formulate the enhanced recovery surgery bundle nursing strategy and apply it to patients with gastric cancer, to explore its safety, effectiveness and feasibility in perioperative gastrointestinal function protection in patients with gastric cancer. Selected the clinical medical records of 100 gastric cancer patients treated in our hospital from June 2019 to June 2021 as the research objects, and divided them into the control group and the observation group with 50 cases in each group according to the random number table. Among them, the control group was given routine nursing measures for nursing intervention, and the observation group was given gastrointestinal enhanced recovery surgery cluster nursing on the basis of the control group. The differences in stress response, gastrointestinal function protection, negative emotions and pain scores of gastric cancer patients before and after nursing were compared between the 2 groups. The postoperative bowel sounds recovery time, first anal exhaust, and first defecation time in the observation group were lower than those in the control group, and the differences were statistically significant (P < .05). Before nursing, there was no significant difference in the scores of stress response changes between the 2 groups (P > .05). After nursing, heart rate (HR), mean arterial pressure (MAP), norepinephrine (NE), and epinephrine (E2) in the observation group were lower than those in the control group, and the difference was statistically significant (P < .05). The pain scores of the 2 groups were significantly improved at different time points, and the observation group was significantly less than the control group, and the difference was statistically significant (P < .05). Gastrointestinal enhanced recovery surgery bundle nursing can effectively improve the gastrointestinal function of patients with gastric cancer, improve the emotional response and stress response of patients, and has certain reference value for the nursing of patients with gastric cancer.

Association between hypertensive disorders of pregnancy and cardiovascular diseases within 24 months after delivery

BACKGROUND

Despite the well-known association between hypertensive disorders of pregnancy and cardiovascular diseases, there are limited data on which specific cardiovascular diagnoses have the greatest risk profiles during the first 24 months after delivery. Most existing data on hypertensive disorders of pregnancy and short-term cardiovascular disease risks are limited to the immediate postpartum period; however, it is crucial to determine cardiovascular disease risk up to 24 months after delivery to inform cardiovascular disease screening protocols during the extended postpartum period.

OBJECTIVE

This study aimed to delineate the risk of cardiovascular diagnoses in the first 24 months after delivery among patients with hypertensive disorders of pregnancy compared with patients without hypertensive disorders of pregnancy.

STUDY DESIGN

This longitudinal population-based study included pregnant individuals with deliveries during 2007 to 2019 in the Maine Health Data Organization's All Payer Claims Data. This study excluded patients with preexisting cardiovascular disease, with multifetal pregnancies, or without continuous insurance during pregnancy. Hypertensive disorders of pregnancy and cardiovascular diseases (categorized by specific conditions: heart failure, ischemic heart disease, arrhythmia or cardiac arrest, cardiomyopathy, cerebrovascular disease or stroke, and new chronic hypertension) were identified using International Classification of Diseases, Ninth Revision, and International Classification of Diseases, Tenth Revision, diagnosis codes. Cox proportional hazards models were used to estimate hazard ratios, adjusting for potential confounding factors.

RESULTS

Of the 119,422 pregnancies examined, the cumulative risk of cardiovascular disease within 24 months after delivery for those with hypertensive disorders of pregnancy vs those without hypertensive disorders of pregnancy was 0.6% vs 0.2% for heart failure, 0.3% vs 0.1% for ischemic heart disease, 0.2% vs 0.2% for arrhythmia or cardiac arrest, 0.6% vs 0.2% for cardiomyopathy, 0.8% vs 0.4% for cerebrovascular disease or stroke, 1.6% vs 0.7% for severe cardiac disease (composite outcome of heart failure, cerebrovascular disease or stroke, or cardiomyopathy), and 9.7% vs 1.5% for new chronic hypertension. After adjustment for potential confounders, those with hypertensive disorders of pregnancy had an increased risk of heart failure, cerebrovascular disease, cardiomyopathy, and severe cardiac disease within the first 24 months after delivery (adjusted hazard ratio, 2.81 [95% confidence interval, 1.90-4.15], 1.43 [95% confidence interval, 1.07-1.91], 2.90 [95% confidence interval, 1.96-4.27], and 1.90 [95% confidence interval, 1.54-2.30], respectively) compared with those without hypertensive disorders of pregnancy. In addition, those with hypertensive disorders of pregnancy had an increased risk for new chronic hypertension diagnosed after 42 days after delivery (adjusted hazard ratio, 7.29; 95% confidence interval, 6.57-8.09). There was no association between hypertensive disorders of pregnancy and ischemic heart disease (adjusted hazard ratio, 0.92; 95% confidence interval, 0.55-1.54) or cardiac arrest or arrhythmia (adjusted hazard ratio, 0.90; 95% confidence interval, 0.52-1.57). In addition, among women with hypertensive disorders of pregnancy, the highest proportion of first cardiovascular disease diagnoses occurred during the first month after delivery for cardiomyopathy (44%), heart failure (39%), cerebrovascular disease or stroke (39%), and severe cardiac disease (41%).

CONCLUSION

Patients with hypertensive disorders of pregnancy had an increased risk of developing new chronic hypertension, heart failure, cerebrovascular disease, and cardiomyopathy within 24 months after delivery. There was no association between hypertensive disorders of pregnancy and ischemic heart disease or cardiac arrest or arrhythmia. Patients with hypertensive disorders of pregnancy need targeted early postpartum interventions and increased monitoring in the first 24 months after delivery. This may preserve long-term health and improve maternal and neonatal outcomes in a subsequent pregnancy.

Association of Prenatal Depression With New Cardiovascular Disease Within 24 Months Postpartum

Background Although depression is well established as an independent risk factor for cardiovascular disease (CVD) in the nonpregnant population, this association has largely not been investigated in pregnant populations. We aimed to estimate the cumulative risk of new CVD in the first 24 months postpartum among pregnant individuals diagnosed with prenatal depression compared with patients without depression diagnosed during pregnancy. Methods and Results Our longitudinal population-based study included pregnant individuals with deliveries during 2007 to 2019 in the Maine Health Data Organization's All Payer Claims Data. We excluded those with prepregnancy CVD, multifetal gestations, or no continuous health insurance during pregnancy. Prenatal depression and CVD (heart failure, ischemic heart disease, arrhythmia/cardiac arrest, cardiomyopathy, cerebrovascular disease, and chronic hypertension) were identified by International Classification of Diseases, Ninth Revision (ICD-9)/International Classification of Diseases, Tenth Revision (ICD-10) codes. Cox models were used to estimate hazard ratios (HRs), adjusting for potential confounding factors. Analyses were stratified by hypertensive disorder of pregnancy. A total of 119 422 pregnancies were examined. Pregnant individuals with prenatal depression had an increased risk of ischemic heart disease, arrhythmia/cardiac arrest, cardiomyopathy, and new hypertension (adjusted HR [aHR], 1.83 [95% CI, 1.20-2.80], aHR, 1.60 [95% CI, 1.10-2.31], aHR, 1.61 [95% CI, 1.15-2.24], and aHR, 1.32 [95% CI, 1.17-1.50], respectively). When the analyses were stratified by co-occurring hypertensive disorders of pregnancy, several of these associations persisted. Conclusions The cumulative risk of a new CVD diagnosis postpartum was elevated among individuals with prenatal depression and persists even in the absence of co-occurring hypertensive disorders of pregnancy. Further research to determine the causal pathway can inform postpartum CVD preventive measures.

Prepregnancy Cardiovascular Disease Risk Factors and Adverse Pregnancy Outcomes in a Safety-Net Hospital

Background: Many adverse pregnancy outcomes (APOs) are associated with elevated cardiovascular disease (CVD) risk. However, APO data in the context of pre-existing CVD risk factors, and from diverse populations, are limited. We assessed the occurrence of APOs among individuals with and without prepregnancy CVD risk factors, overall and by race/ethnicity. Methods: We conducted a retrospective study using electronic medical record data from a large urban safety-net hospital. Individuals with prenatal care and delivery between 2016 and 2018 at the hospital were included, and data from prenatal intake through the delivery hospitalization were captured. The exposure, prepregnancy CVD risk factors (hypertension, diabetes, tobacco use, and obesity), and the outcome, APOs (hypertensive disorders of pregnancy, gestational diabetes, preterm delivery, low birth weight, and stillbirth), were identified from electronic medical records. Results: We identified 3760 unique delivering individuals, of whom 55.1% self-identified as Black non-Hispanic and 17% as Hispanic. Prepregnancy CVD risk factor prevalence was 45.6%, most commonly obesity (26.6%). APO prevalence was 35.6%, most commonly a hypertensive disorder of pregnancy (20.1%). Overall, 45.7% of APOs occurred in the absence of recognized prepregnancy CVD risk factors, representing 16.3% of the total sample. Among individuals without prepregnancy CVD risk factors, APO prevalence was 30.0% and did not vary by race/ethnicity. Conclusions: In this racially and ethnically diverse hospital-based sample, APOs were present in one in three parous individuals without prepregnancy CVD risk factors-a group with potentially elevated CVD risk who might otherwise be missed by traditional CVD risk factor screening.

Effects of omega-3 supplementation on glucose and lipid metabolism in patients with gestational diabetes: A meta-analysis of randomized controlled trials

AIM

We assessed whether omega-3 supplementation could improve glucose and lipid metabolism, insulin resistance, and inflammatory factors in individuals with gestational diabetes mellitus (GDM).

METHODS

In this meta-study, we used a random-effects or fixed-effects meta-analysis model to analyze the mean differences (MD) and corresponding 95 % confidence intervals (CI) before and after omega-3 and placebo supplementation, thus evaluating the effects of omega-3 on glucose and lipid metabolism, insulin resistance, and inflammatory factors.

RESULTS

Six randomized controlled trials (331 participants) were included in the meta-analysis. The levels of fasting plasma glucose (FPG) (WMD = -0.25 mmol/L; 95 % CI: -0.38, -0.12), fasting insulin (WMD = -17.13 pmol/L; 95 % CI: -27.95, -6.30), and homeostasis model of assessment-insulin resistance (WMD = -0.51; 95 % CI: -0.89, -0.12) were lower in the omega-3 group compared to their levels in the placebo group. The results of the analysis of lipid metabolism showed that triglycerides (WMD = -0.18 mmol/L; 95 % CI: -0.29, -0.08) and very low-density lipoprotein cholesterol (WMD = -0.1 mmol/L; 95 % CI: -0.16, -0.03) decreased in the omega-3 group, while high-density lipoproteins (WMD = 0.06 mmol/L; 95 % CI: 0.02, 0.10) increased. Compared to the placebo group, inflammatory factor serum C-reactive protein (SMD = -0.68 mmol/L; 95 % CI: -0.96, -0.39) decreased in the omega-3 group.

CONCLUSION

Omega-3 supplementation can decrease the levels of FPG and inflammatory factors, enhance blood lipid metabolism, and reduce insulin resistance in patients with GDM.

Clinical presentation, investigation, underlying causes, and subsequent pregnancy outcomes among different phenotypes of second trimester miscarriage

AIM

To evaluate the causes of miscarriage and subsequent pregnancy outcomes among different phenotypes of second trimester miscarriage.

METHODS

Retrospective analysis of 170 consecutive second trimester miscarriages between 14 + 0 and 23 + 6 weeks recorded in the Clinical Data Analysis and Reporting System from 2012 to 2021. Cases were excluded if miscarriages occurred before 14 + 0 weeks of gestation, data were incomplete, or passage of the fetus happened before the clinical assessment. Cases were classified with a stepwise approach into three phenotypic groups including silent miscarriages (ST-SM), rupture of membranes (ST-ROM), and inevitable miscarriages (ST-IM) depending on the fetal heart pulsation and leakage of liquor at presentation. Clinical investigation of the underlying causes and the outcome of the subsequent pregnancy was then reviewed.

RESULTS

There were 97 cases of ST-SM, 21 cases of ST-ROM, and 52 cases of ST-IM. Placental histology and karyotype examination were more likely to yield significant results in the cases of ST-ROM and ST-SM (p < 0.05). The phenotypic examination identified different underlying causes including fetal anomaly, suspected cervical insufficiency, diabetes mellitus, and unknown causes (p < 0.001). Sixty-four cases achieved a subsequent pregnancy. Although women with history of ST-ROM and ST-IM received more cervical length monitoring and cervical cerclage than those with ST-SM (66.7% vs. 44.4% vs. 7.5%, p = 0.0002; and 16.7% vs. 22.2% vs. 2.5%, p = 0.031, respectively), the risk of recurrent second trimester miscarriage was higher in ST-ROM and ST-IM than in ST-SM (16.7% vs. 0%, p = 0.018).

CONCLUSION

The classification can differentiate different second trimester miscarriage phenotypes, which offers essential information to guide investigation panels of the underlying cause of miscarriages, and the prognosis and management of subsequent pregnancy. Future researches focused on second trimester miscarriage should report their findings according to different phenotypes.

Prevalences of cardiometabolic risk and lifestyle factors in young parents: evidence from a German birth cohort study

BACKGROUND

Studies show that parents significantly impact their children's health through their cardiometabolic risk profile and health behavior. There is only little information about the prevalence of cardiometabolic risk factors and lifestyle factors among new parents yet. The aims of this study are therefore to evaluate the prevalences of cardiometabolic risk factors in parents of infants in Germany and to examine their lifestyle and health behavior.

METHODS

In the KUNO-Kids health study, an ongoing birth cohort, parents (n = 930 mothers and 769 fathers) were asked about cardiometabolic risk factors (obesity/hypertension/type 2 diabetes mellitus) and lifestyle factors (dietary/sports/smoking habits/alcohol consumption) during the first year after the birth of their children via questionnaires. Chi-square as well as fisher exact tests were conducted to analyse associations between lifestyle factors and cardiometabolic risk factors.

RESULTS

34.2% of mothers and 58.5% of fathers were overweight or obese. In 11.8% of the families, at least one parent suffered from hypertension, in 2.4% from type 2 diabetes mellitus. One year after delivery, 8.5% of mothers were smoking, 6.9% showed a risky alcohol consumption (> 10 g/d). 16.0% of fathers were smoking 4 weeks after childbirth, 10.7% showed risky alcohol consumption (> 20 g/d). 21.6% of mothers carried out sports activity for more than 2 h a week then. Parental hypertension was linked to a higher prevalence of risky alcohol consumption, obesity to a lower prevalence of daily fruits consumption.

CONCLUSIONS

Cardiometabolic risk factors were widespread among new parents with obesity and overweight having the highest prevalences. A considerable number of parents also practiced an unhealthy lifestyle showing that there is potential for improvement to promote the healthy development of their children.

Preeclampsia and Fetal Growth Restriction as Risk Factors of Future Maternal Cardiovascular Disease-A Review

Cardiovascular diseases (CVDs) remain the leading cause of death in women worldwide. Although traditional risk factors increase later-life CVD, pregnancy-associated complications additionally influence future CVD risk in women. Adverse pregnancy outcomes, including preeclampsia and fetal growth restriction (FGR), are interrelated disorders caused by placental dysfunction, maternal cardiovascular maladaptation to pregnancy, and maternal abnormalities such as endothelial dysfunction, inflammation, hypercoagulability, and vasospasm. The pathophysiologic pathways of some pregnancy complications and CVDs might be linked. This review aimed to highlight the associations between specific adverse pregnancy outcomes and future CVD and emphasize the importance of considering pregnancy history in assessing a woman's CVD risk. Moreover, we wanted to underline the role of maternal cardiovascular maladaptation in the development of specific pregnancy complications such as FGR.

Proprotein Convertase Subtilisin Kexin 9 (PCSK9) and nonHDL Particles Rise During Normal Pregnancy and Differ by BMI

BACKGROUND

Serum lipids, including total cholesterol (TC), triglycerides (TG), and low-density lipoprotein cholesterol (LDL-c), increase during pregnancy. Serum Proprotein Convertase Subtilisin Kexin 9 (PCSK9) is a vital regulator in lipoprotein metabolism. Circulating PCSK9 downregulates the LDL receptor on the surface of liver cells inhibiting clearance of LDL-c.

OBJECTIVE

To determine the influence of weeks of pregnancy and obesity on circulating levels of essential lipid lipoproteins and PCSK9 in women with normal, uncomplicated pregnancies and deliveries.

METHODS

We performed a comprehensive lipid and lipoprotein profile during each trimester of pregnancy in 70 mostly Caucasian women with uncomplicated normal pregnancies and deliveries. Based on their first trimester BMI, we placed them into one of three categories: (<25 kg/m² n=23, 25-30 kg/m² n=25, or >30 n=22) kg/m². Cholesterol, triglycerides, LDL cholesterol (LDL-c), non-HDL particles, and lipoprotein(a) were measured by spectrophotometry, ion mobility, and immunoturbidimetric assays. Elisa assay determined PCSK9 (active and total). Homeostatic Model Assessment (HOMA-IR) assessed insulin resistance in the second and third trimesters of pregnancy.

RESULTS

Total and active PCSK9, LDL-c, and nonHDL particle concentrations were higher than reported for non-pregnant normal values, increased after the first trimester of pregnancy, and were highest from mid-gestation to the last trimester of pregnancy in the overweight and the obese.

CONCLUSION

PCSK9 levels rise as normal pregnancy progresses. Levels are higher in persons who are obese, even after adjustment for insulin resistance. Defining normal PCSK9 levels during pregnancy must adjust for gestational age and BMI.

Contribution of maternal cardiometabolic risk factors to racial-ethnicity disparities in preterm birth subtypes

BACKGROUND

There are recognized racial-ethnic disparities in preterm birth and in maternal cardiometabolic risk factors likely linked to systemic racism. However, it is unclear the extent to which cardiometabolic risk factors contribute to the higher rates of preterm birth among minoritized populations.

OBJECTIVE

This study aimed to evaluate racial-ethnic disparities in preterm birth subtypes and the role of maternal cardiometabolic risk factors as mediators of the association between maternal race-ethnicity and preterm birth subtypes.

STUDY DESIGN

This was a retrospective cohort study of 295,210 singleton live births from 2011 to 2018. Preterm birth subtypes were defined as medically indicated and spontaneous preterm birth. Poisson regression with robust standard errors were used to provide estimates of the relative risks and 95% confidence intervals for preterm birth subtypes. Causal mediation analysis used logistic regression models to estimate the natural direct and natural indirect (mediated) effects of maternal cardiometabolic risk factors.

RESULTS

Compared with White individuals, Black, Asian, and Hispanic individuals were at increased risk for having both medically indicated preterm birth (1.45, 1.30-1.61; 1.21, 1.12-1.31; and 1.13, 1.05-1.22, respectively) (risk ratios, 95% confidence intervals, respectively) and spontaneous preterm birth (1.20, 1.08-1.34; 1.34, 1.26-1.43; and 1.16, (1.08-1.23), independent of established risk factors. The extent to which cardiometabolic risk factors mediated the associations between race-ethnicity (each group vs White in separate analyses) and preterm birth subtypes varied by race-ethnicity. Hypertensive disorders mediated 30.1% of the association between Black race-ethnicity and medically indicated preterm birth, but it did not mediate the association for other racial-ethnic groups or for spontaneous preterm birth. Any glucose disorder in pregnancy was a mediator of medically indicated preterm birth and spontaneous preterm birth for Asian (65.8% and 13.9%, respectively) and Hispanic (17.3% and 11.9%) race-ethnicity but not for Black race-ethnicity. Overweight or obesity mediated the association between race-ethnicity and medically indicated preterm birth (15.5% among Black individuals and 25.1% among Hispanic individuals) and spontaneous preterm birth (10.7% among Hispanic individuals) but was not a mediator among Asian individuals.

CONCLUSION

Black, Asian, and Hispanic individuals are at increased risk for preterm birth. Maternal cardiometabolic risk factors partially mediate the associations between race-ethnicity and preterm birth subtypes but the extent varies by race-ethnicity. These findings suggest that strategies that improve and diminish differences in cardiometabolic health between race-ethnicity populations may diminish disparities in preterm birth.

Primary Care-Based Cardiovascular Disease Risk Management After Adverse Pregnancy Outcomes: a Narrative Review

Several common adverse pregnancy outcomes can reveal subclinical or latent cardiovascular disease (CVD) risk, transiently exposed through the physiologic stress of pregnancy. The year after pregnancy may be a singular opportunity to identify and initiate treatment for CVD risk, even before the onset of traditional CVD risk factors. However, clinical guidance regarding CVD risk management after adverse pregnancy outcomes is lacking. We therefore conducted a systematic review of US clinical practice guidelines and professional society recommendations to inform primary care-based CVD risk management after adverse pregnancy outcomes. We identified 13 relevant publications. While most recommendations were based on limited or weak evidence, we identified several areas of consensus. First, individuals with an adverse pregnancy outcome associated with future CVD are likely to benefit from CVD risk assessment-accompanied by education, counseling, and support for lifestyle modification-beginning within the first postpartum year. Second, among clinicians, clear and consistent documentation about adverse pregnancy outcomes and recommended follow-up is important to coordinate care after pregnancy. In addition, patients need to be informed about their pregnancy complications and associated CVD risks, so that they can make informed health care and lifestyle decisions. Finally, in general, CVD prevention in the year after an adverse pregnancy outcome focuses on lifestyle modification, reserving pharmacotherapy for the highest-risk patients and those with traditional CVD risk factors. While postpartum lifestyle interventions show promise for reducing CVD risk after adverse pregnancy outcomes, continued research to determine the optimal content, timing, and long-term effects of such interventions is needed.

Does Adding Adverse Pregnancy Outcomes Improve the Framingham Cardiovascular Risk Score in Women? Data from the Tehran Lipid and Glucose Study

Background Limited and conflicting evidence is available regarding the predictive value of adding adverse pregnancy outcomes (APOs) to established cardiovascular disease (CVD) risk factors. Hence, the objective of this study was to determine whether adding APOs to the Framingham risk score improves the prediction of CVD events in women. Methods and Results Out of 5413 women who participated in the Tehran Lipid and Glucose Study, 4013 women met the eligibility criteria included for the present study. The exposure and the outcome variables were collected based on the standard protocol. Cox proportional hazard model was used to evaluate the association of APOs and CVDs. The variant of C-statistic for survivals and reclassification of subjects into Framingham risk score categories after adding APOs was reported. Out of the 4013 eligible subjects, a total of 1484 (36.98%) women reported 1 APO, while 395 (9.84%) of the cases reported multiple APOs. Univariate proportional hazard Cox models showed the significant relations between CVD events and APOs. The enhanced model had a higher C-statistic indicating more acceptable discrimination as well as a slight improvement in discrimination (C-statistic differences: 0.0053). Moreover, we observed a greater risk of experiencing a CVD event in women with a history of multiple APOs compared with cases with only 1 APO (1 APO: hazard ratio [HR] = 1.22; 2 APOs: HR; 1.94; ≥3 APOs: HR = 2.48). Conclusions Beyond the established risk factors, re-estimated CVDs risk by adding APOs to the Framingham risk score may improve the accurate risk estimation of CVD. Further observational studies are needed to confirm our findings.

Dihydroartemisinin improves hypercholesterolemia in ovariectomized mice via enhancing vectorial transport of cholesterol and bile acids from blood to bile

The increase of concentrations of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) in the serum of postmenopausal women is the important risk factor of the high morbidity of cardiovascular diseases of old women worldwide. To test the anti-hypercholesterolemia function of dihydroartemisinin (DHA) in postmenopausal women, ovariectomized (OVX) mice were generated, and DHA were administrated to OVX mice for 4 weeks. The blood and liver tissues were collected for biochemical and histological tests respectively. The mRNA and protein expression levels of genes related to metabolism and transport of cholesterol, bile acid and fatty acid in the liver or ileum were checked through qPCR and western blot. DHA could significantly reduce the high concentrations of TC and LDL-C in the serum and the lipid accumulation in the liver of ovariectomized mice. The expression of ABCG5/8 was reduced in liver of OVX mice, and DHA could up-regulate the expression of them. Genes of transport proteins for bile salt transport from blood to bile, including Slc10a1, Slco1b2 and Abcb11, were also significantly up-regulated by DHA. DHA also down-regulated the expression of Slc10a2 in the ileum of OVX mice to reduce the absorption of bile salts. Genes required for fatty acid synthesis and uptake, such as Fasn and CD36, were reduced in the liver of OVX mice, and DHA administration could significantly up-regulate the expression of them. These results demonstrated that DHA could improve hypercholesterolemia in OVX mice through enhancing the vectorial transport of cholesterol and bile acid from blood to bile.

Mapping of high-risk detection of women pregnancy on antenatal care in Talise Health Center, Palu City, Indonesia

OBJECTIVE

This study aimed to map pregnant women with high-risk pregnancies based on age, parity, pregnancy history, childbirth history, illness history, and CED status history as well as the relationship between the six factors.

METHOD

This study utilized a survey method with descriptive data without the intervention of variables but observed phenomena or sought the relationship between phenomena and other variables. The survey was conducted with an approach using Geographic Information Systems (GIS). There were 243 respondents obtained using the Lemeshow formula, while the data were analyzed using spatial techniques and Chi-Square test with p>0.05.

RESULTS

The results of spatial analysis using a 1: 50,000 scale map showed that; (1) high-risk and very high-risk pregnancies dominated Talise, (2) based on age, parity, pregnancy history, childbirth history, illness history, and CED status, cases of high-risk pregnancies were all detected in Talise, (3) age (p=0.000). Furthermore, pregnancy history (p=0.004) correlated with a high-risk pregnancy. Besides, parity, childbirth history, illness history, and CED status did not correlate with high-risk pregnancy since the p-value>0.05; (4) age and pregnancy history influenced the high-risk pregnancy.

Praegnatio Perturbatio-Impact of Endocrine-Disrupting Chemicals

The burden of adverse pregnancy outcomes such as preterm birth and low birth weight is considerable across the world. Several risk factors for adverse pregnancy outcomes have been identified. One risk factor for adverse pregnancy outcomes receiving considerable attention in recent years is gestational exposure to endocrine-disrupting chemicals (EDCs). Humans are exposed to a multitude of environmental chemicals with known endocrine-disrupting properties, and evidence suggests exposure to these EDCs have the potential to disrupt the maternal-fetal environment culminating in adverse pregnancy and birth outcomes. This review addresses the impact of maternal and fetal exposure to environmental EDCs of natural and man-made chemicals in disrupting the maternal-fetal milieu in human leading to adverse pregnancy and birth outcomes-a risk factor for adult-onset noncommunicable diseases, the role lifestyle and environmental factors play in mitigating or amplifying the effects of EDCs, the underlying mechanisms and mediators involved, and the research directions on which to focus future investigations to help alleviate the adverse effects of EDC exposure.

Team-Based Care of Women With Cardiovascular Disease From Pre-Conception Through Pregnancy and Postpartum: JACC Focus Seminar 1/5

The specialty of cardio-obstetrics has emerged in response to the rising rates of maternal morbidity and mortality related to cardiovascular disease (CVD) during pregnancy. Women of childbearing age with or at risk for CVD should receive appropriate counseling regarding maternal and fetal risks of pregnancy, medical optimization, and contraception advice. A multidisciplinary cardio-obstetrics team should ensure appropriate monitoring during pregnancy, plan for labor and delivery, and ensure close follow-up during the postpartum period when CVD complications remain common. The hemodynamic changes throughout pregnancy and during labor and delivery should be considered with respect to the individual cardiac disease of the patient. The fourth trimester refers to the 12 weeks after delivery and is a key time to address contraception, mental health, cardiovascular risk factors, and identify any potential postpartum complications. Women with adverse pregnancy outcomes are at increased risk of long-term CVD and should receive appropriate education and longitudinal follow-up.

Prenatal Maternal Docosahexaenoic Acid (DHA) Supplementation and Newborn Anthropometry in India: Findings from DHANI

Long-chain omega-3 fatty acid status during pregnancy may influence newborn anthropometry and duration of gestation. Evidence from high-quality trials from low- and middle-income countries (LMICs) is limited. We conducted a double-blind, randomized, placebo-controlled trial among 957 pregnant women (singleton gestation, 14-20 weeks' gestation at enrollment) in India to test the effectiveness of 400 mg/day algal docosahexaenoic acid (DHA) compared to placebo provided from enrollment through delivery. Among 3379 women who were screened, 1171 were found eligible; 957 were enrolled and were randomized. The intervention was two microencapsulated algal DHA (200 × 2 = 400 mg/day) or two microencapsulated soy and corn oil placebo tablets to be consumed daily from enrollment (≤20 weeks) through delivery. The primary outcome was newborn anthropometry (birth weight, length, head circumference). Secondary outcomes were gestational age and 1 and 5 min Appearance, Pulse, Grimace, Activity, and Respiration (APGAR) score. The groups (DHA; n = 478 and placebo; n = 479) were well balanced at baseline. There were 902 live births. Compliance with the intervention was similar across groups (DHA: 88.5%; placebo: 87.1%). There were no significant differences between DHA and placebo groups for birth weight (2750.6 ± 421.5 vs. 2768.2 ± 436.6 g, p = 0.54), length (47.3 ± 2.0 vs. 47.5 ± 2.0 cm, p = 0.13), or head circumference (33.7 ± 1.4 vs. 33.8 ± 1.4 cm, p = 0.15). The mean gestational age at delivery was similar between groups (DHA: 38.8 ± 1.7 placebo: 38.8 ± 1.7 wk, p = 0.54) as were APGAR scores at 1 and 5 min. Supplementing mothers through pregnancy with 400 mg/day DHA did not impact the offspring's birthweight, length, or head circumference.

Different dose of heparin in preventing radial artery occlusion after transradial coronary angiography: A protocol for systematic review and meta-analysis of randomized controlled trials

BACKGROUND

When atherosclerosis occurs in the coronary artery, resulting in stenosis, occlusion, or spasm of the coronary artery, the supply of blood and oxygen to the myocardium will be reduced or even unavailable, resulting in myocardial necrosis and heart pain, chest tightness, dyspnea and other symptoms caused by myocardial necrosis are collectively referred to as coronary atherosclerotic heart disease. Coronary angiography can not only understand the degree of coronary artery damage, but also estimate the prognosis of coronary artery stenting, which provides a reliable reference for clinical treatment. Transradial coronary angiography (TCA) has the advantages of high success rate, small trauma, less complications, no bed rest, reduce hospital stay and other superiority, which accepted and used by physicians. Although the success rate of surgery is high, the postoperative complications will still affect the effect of surgery and the prognosis of patients. The main manifestations are radial artery occlusion (RAO), forearm hematoma formation, pseudoaneurysm formation, periosteal compartment syndrome, radial artery perforation, etc. Among the many ways to prevent RAO, anticoagulant therapy with common heparin is one of them, but the dosage of heparin is not clear. Therefore, we decided to use systematic evaluation to evaluate the clinical effectiveness and safety of different dose of heparin in preventing of RAO, and to provide clinical basis for the early prevention and treatment of RAO.

METHODS

Two reviewers independently searched PubMed, Embase, the Cochrance Library, Web of Science, Medline, CBM Disc, CNKI, and WANFANG Data to find the eligible research. The retrieval about the randomized controlled trials of different dose of heparin in preventing the occurrence of RAO after TCA in recent years. The retrieval time is set between January 1990 and June 2020. The retrieval language is Chinese/English. Two researchers independently searched, managed and screened the literature through the search terms. When the 2 parties have inconsistent opinions on the inclusion or not of certain literature, the literature will be referred to the third researcher for discussion and decision. The included studies are conducted bias risk assessment through bias risk assessment tool, which based on Cochrane Handbook 5.0. The extracted data uses RevMan5.3 software for statistical processing.

RESULTS

The research results of this systematic review will be published in peer-reviewed medical-related academic journals.

CONCLUSION

This study adopts the Meta-analysis method and expands the sample size, which will give high-quality evidence-based medicine evidence on the clinical effectiveness and safety of different dose of heparin in preventing the occurrence of RAO.
