Maternal cardiovascular health in early pregnancy and the risk of congenital heart defects in offspring

BACKGROUND

Congenital heart disease (CHD) is the predominant birth defect. This study aimed to explore the association between maternal cardiovascular health (CVH) and the CHD risk in offspring.

METHODS

We used the prospective data from the Fujian Birth Cohort Study, collected from March 2019 to December 2022 on pregnant women within 14 weeks of gestation. Overall maternal CVH was assessed by seven CVH metrics (including physical activity, smoking, sleep duration, body mass index, blood pressure, total cholesterol, and fasting plasma glucose), with each metric classified as ideal, intermediate or poor with specific points. Participants were further allocated into high, moderate and low CVH categories based on the cumulative CVH score. The association with offspring CHD was determined with log-binominal regression models.

RESULTS

A total of 19810 participants aged 29.7 (SD: 3.9) years were included, with 7846 (39.6%) classified as having high CVH, 10949 (55.3%) as having moderate CVH, and 1015 (5.1%) as having low CVH. The average offspring CHD rate was 2.52%, with rates of 2.35%, 2.52% and 3.84% across the high, moderate and low CVH categories, respectively (P = 0.02). Adjusted relative risks (RRs) of having offspring CHD were 0.64 (95% CI: 0.45-0.90, P = 0.001) for high CVH and 0.67 (95% CI: 0.48-0.93, P = 0.02) for moderate CVH compared to low CVH. For individual metrics, only ideal total cholesterol was significantly associated with lower offspring CHD (RR: 0.73, 95% CI: 0.59-0.83, P = 0.002).

CONCLUSIONS

Pregnant women of high or moderate CVH categories in early pregnancy had reduced risks of CHD in offspring, compared to those of low CVH. It is important to monitor and improve CVH during pre-pregnancy counseling and early prenatal care.

The effect of cognitive-behavioral therapy and haptonomy on fear of childbirth in primigravida women: a randomized clinical trial

BACKGROUND

Considering the role of fear of childbirth (FOC) in the enhancement of unnecessary cesarean sections (CS), the present study aimed at evaluating the effect of Cognitive-Behavioral Therapy (CBT) and haptonomy on the FOC (as primary outcome) and intended birth method and final birth method (as secondary outcomes) among primigravida women.

METHODS

This randomized clinical trial was conducted on 99 primigravida women in Tabriz, Iran 2022. Participants were assigned to three groups with a ratio of 1:1:1 using stratified block randomization based on the fear intensity. One of the intervention groups (n = 33) received eight group sessions of CBT from 24 to 28 weeks of gestation and the other intervention group (n = 33) received haptonomy during seven sessions once a week. The control group (n = 33) received routine prenatal care. The Wijma questionnaire was completed by the participants before the intervention, after the intervention at 35-37 weeks of gestation, and after birth. The intended birth method was investigated before and after the intervention at 35-37 weeks of gestation. The final birth method and the reasons for CS were recorded based on the mother's medical profile. The one-way ANOVA was used before the intervention and RMANOVA after the intervention to compare the mean scores of FOC among the three groups. Further, chi-square test was applied to compare the intended and final birth method.

RESULTS

The mean (standard deviation: SD) of FOC in the CBT group changed from 74.09 (11.35) at 24-28 weeks of gestation to 46.50 (18.28) at 35-37 weeks and 48.78 (20.64) after birth (P < 0.001). The means (SDs) of FOC in the haptonomy group were 76.81 (13.09), 46.59 (15.81), and 45.09 (20.11), respectively (P < 0.001). The mean (SD) of FOC in the control group decreased from 70.31 (6.71) to 66.56 (18.92) and then, increased to 71.00 (21.14) after birth (P = 0.878). After the intervention, there was no statistically significant difference among the three groups in terms of the intended birth method (P = 0.278), and final birth method (P = 0.107).

CONCLUSION

The findings of the present study revealed that both CBT and haptonomy interventions reduce FOC. Although the desire for vaginal birth and final vaginal birth in the haptonomy group was more than that in the other two groups, there was no statistically significant difference among the three groups.

The relationship between pregnancy and birth experience with maternal-fetal attachment and mother-child bonding: a descriptive-analytical study

BACKGROUND

Pregnancy and childbirth experience can be important factors for a pleasant relationship between mother and baby. This study assessed the relationship between the pregnancy and birth experience with maternal-fetal attachment (MFA) and mother-child bonding.

METHODS

A descriptive-analytical study was conducted among 228 pregnant women in Tabriz, Iran February 2022 to March 2023. Using cluster random sampling method, we included 228 women with gestational age 28-36 weeks and followed them up until six weeks postpartum. Data were collected in two stages using the following questionnaires: Pregnancy Experience Scale (hassles and uplifts), Maternal-Fetal Attachment Questionnaire (during the third trimester of pregnancy), Postpartum Bonding Questionnaire, and Childbirth Experience Questionnaire (six weeks postpartum). Data were analyzed using Pearson's correlation test and general linear model.

RESULTS

The mean score of MFA was significantly higher among women with feelings of being uplifted during pregnancy [β (95% CI) = 1.14 (0.87 to 1.41); p < 0.001]. However, there was no statistically significant relationship between pregnancy hassles and MFA and mother-child bonding (p > 0.05). Also, there was no statistically significant relationship between childbirth experience and mother-child bonding (p > 0.05).

CONCLUSION

According to the results of this study, pregnancy uplifts have a positive role in improving MFA. Therefore, it is recommended to plan interventions to make pregnancy period a pleasant experience for mothers.

'A small person that we made' - Parental conceptualisation of the unborn child: A constructivist grounded theory

BACKGROUND

The way that expectant parents think and feel about the fetus during pregnancy is thought to be somewhat predictive of their later relationship with the child. However, efforts to identify determinants, correlates and consequences of the parental-fetal tie have had conflicting results. This is likely to be partially attributable to issues in existing conceptualisations of the phenomenon.

OBJECTIVE

The purpose of the study was to construct substantive theory of expectant parents' fetal conceptual and relational experiences.

METHODS

Constructivist grounded theory was used to explore data generated through individual, semi-structured interviews conducted with nine first-time expectant mothers and their male partners residing in Malta, in early, middle and late pregnancy. Analysis included techniques of coding, constant comparison and memo-writing.

FINDINGS

Expectant mothers and fathers conceptualise and connect to the fetus through comparable processes, despite physical disparities in the pregnancy experience. Coming to think of the fetus as a known other and part of the intimate family is vital in achieving a sense of relatedness. An increasingly tangible fetus facilitates such an outlook. However, the extent of accessibility to fetal palpability and reciprocity consistently fail to satisfy parental yearnings.

CONCLUSIONS

Given the convoluted and individualised nature of the parental-fetal tie, accurate measurement of this through the use of self-report instruments is likely to remain challenging. Instead, midwives can talk to expectant parents in-depth about their feelings regarding the unborn child and seek to address any concerns. Further longitudinal research spanning the transition to parenthood is needed to understand the postpartum sequelae of the processes observed antenatally.

Prevalence and materno-fetal outcomes of preeclampsia/eclampsia amongst pregnant women at a teaching hospital in north-central Nigeria: a retrospective cross-sectional study

Background

Preeclampsia/eclampsia (PE/E) contributes significantly to maternal, perinatal morbidity and mortality in Nigeria. The objectives of the study were to ascertain the prevalence, materno-fetal outcomes and sociodemographic factors associated with PE/E at Nigerian Teaching Hospital from September 2014 to August 2019.

Methods

This was a retrospective cross-sectional study that analyzed deidentified secondary data of women managed for PE/E at a teaching hospital in north-central, Nigeria. Descriptive statistics were used to determine sample characteristics and study outcome estimates. Bivariate analysis was used to test for associations between sociodemographic factors and PE/E, materno-fetal outcomes while logistic regression analysis was used to test for the magnitude of these associations. The significance level was set at P < 0.05.

Results

The prevalence of PE/E in this study was 3.60%. Preeclampsia was diagnosed in 3.02% of cases while eclampsia was the diagnosis in 0.58%. Case fatality rate was 3.9% and still birth rate was 10.7%. Majority of women (85.4%) did not have any maternal complication nor unfavorable outcome. Majority (67.7%), of babies weighed less than 2500 g and birth weight was the only sociodemographic factor that was significantly associated with fetal outcome (X² = 15.6, P < 0.001).

Conclusions

The prevalence of PE/E in this study is high and is associated with high maternal and perinatal deaths. Majority of the cases of PE/E as well the fatalities occurred in women who had no formal education, unbooked and referred to the teaching hospital with worsening conditions. There is need for explorative research on community factors associated with PE/E and its outcome towards prevention and early management of cases.

Immune system: development and acquisition of immunological competence

OBJECTIVES

To describe the ontogeny of the immune system and the adaptive mechanisms of the immune system in the neonatal period, with an emphasis on transplacental antibody transport and breastfeeding.

SOURCE OF DATA

Non-systematic literature review in the PubMed database.

SUMMARY OF THE FINDINGS

The last two decades have witnessed a great advance in the knowledge of the immune system since conception. Several investigation tools have provided insight on phenomena that were previously inadequately understood. Still expanding, the functional and molecular investigation of various aspects of the immune system will make it possible to understand how intra-uterus maternal-fetal exchanges, the maternal microbiota interacting with the fetus and newborn, and the acquisition of immunological competence occur in healthy and disease scenarios.

CONCLUSIONS

In-depth knowledge of the development of the immune system and of the adaptive mechanisms that allow a safer transition to the extrauterine environment are fundamental components of optimizing maternal and young infant vaccination, as well as the strategies associated with full postnatal development, and the early diagnosis and treatment of innate errors of immunity.

Effects of a mindfulness-based childbirth and parenting program on maternal-fetal attachment: A randomized controlled trial among Iranian pregnant women

BACKGROUND AND PURPOSE

Although mindfulness-based childbirth and parenting is suggested to promote maternal-fetal attachment, no study has yet addressed its potential effects. This study aimed to determine the effects of a mindfulness-based childbirth and parenting program on maternal-fetal attachment among Iranian pregnant women.

MATERIALS AND METHODS

This study was conducted on pregnant women, who were divided into two groups to either receive routine care plus mindfulness training for childbirth and parenting (i.e., eight 2-h group sessions once a week and one 3-h session of silent meditation) or receive routine care alone. Maternal-fetal attachment was evaluated by the Cranley's Maternal-Fetal Attachment Scale.

RESULTS

After the intervention, the total score of maternal-fetal attachment was significantly higher in the experimental group (P < 0.001; effect size = 0.640). In the intervention group, all dimensions of maternal-fetal attachment significantly improved, except the dimension of "differentiation of self from the fetus", whereas in the control group, only the dimension of "attributing characteristics to the fetus" improved.

CONCLUSION

The implemented program in this study was potentially effective in promoting maternal-fetal attachment.

[Correlations among Perceptions and Practice of Taegyo and Maternal-Fetal Attachment in Pregnant Women]

PURPOSE

This study was conducted to examine the relationships among the perceptions and practice of taegyo (a traditional set of practices and beliefs related to healthy fetal development) and maternal-fetal attachment in pregnant women.

METHODS

The participants were 136 pregnant women who visited a public health center or maternity hospital for prenatal care. The collected data were analyzed using descriptive statistics, the t-test, analysis of varience, and Pearson correlation coefficients with SPSS version 22.0.

RESULTS

The mean age of the pregnant women was 32.24±3.99 years. The mean scores for perceptions of taegyo, practice of taegyo, and maternal-fetal attachment were 3.96±0.53, 3.74±0.64, and 3.94±0.49, respectively. Perceptions of taegyo were significantly correlated with the practice of taegyo (r=.72, p<.001), and maternal-fetal attachment (r=.55, p<.001). A significant correlation was also found between the practice of taegyo and maternal-fetal attachment (r=.65, p<.001).

CONCLUSION

Perceptions of taegyo affected the practice of taegyo, and had a positive effect on maternal-fetal attachment. These findings suggest that primary care nurses at hospitals and public health centers should provide nursing intervention programs to improve the perceptions of taegyo, the practice of taegyo, and maternal-fetal attachment.

[The effect of pre-pregnancy weight and the increase of gestational weight on fetal growth restriction: a cohort study]

Objective: To investigate the effect of pre-pregnancy weight and the increase of gestational weight on fetal growth restriction. Methods: From May 2013 to September 2014, a total of 3 474 pregnant women who took their first antenatal care and willing to undergo their prenatal care and delivery in Ma 'anshan Maternity and Child Care Centers were recruited in the cohort study. Excluding subjects without weight data before delivery (n=54), pregnancy termination (n=162), twins live births (n=39), without fetal birth weight data (n=7), 3 212 maternal-singleton pairs were enrolled for the final data analysis. Demographic information of pregnant woman, pregnancy history, disease history, height and weight were collected. In the 24(th)-28(th), 32(nd)-36(th) gestational week and childbirth, three follow-up visits were undertaken to collect data of pregnancy weight, pregnancy vomiting, gestational hypertension, gestational diabetes mellitus, newborn gender and birth weight. χ(2) test was used to compare the detection rate of fetal growth restriction in different groups. Multivariate unconditional logistic regression model and spreadsheet were used to analyze the independent and interaction effect of pre-pregnancy weight and the increase of gestational weight on fetal growth restriction. Results: The incidence of fetal growth restriction was 9.7%(311/3 212). The incidence of fetal growth restriction in pre-pregnancy underweight group was 14.9% (90/603), higher than that in normal pre-pregnancy weight group (8.7% (194/2 226)) (χ(2)=24.37, P<0.001). The incidence of fetal growth restriction in inadequate increase of gestational weight group was 17.9% (50/279), higher than the appropriate increase of weight group (11.8% (110/932)) (χ(2)=36.89, P<0.001). Multivariate unconditional logistic regression analysis showed that compared with normal pre-pregnancy weight group, pre-pregnancy underweightwas a risk factor for fetal growth restriction, with RR (95%CI) at 1.76 (1.34-2.32); Compared with the appropriate increase of gestational weight group, inadequate weight increase during pregnancy was a risk factor for fetal growth restriction, with the RR (95%CI) at 1.70 (1.17-2.48). No additive model interaction [relative excess risk of interaction, attributable proportions of interaction, the synergy index and their 95%CI were 0.75 (-2.14-3.63), 0.21 (-0.43-0.86) and 1.43 (0.45-4.53), respectively] or multiplication model interaction (RR (95%CI): 1.00 (0.44-2.29)) existed between pre-pregnancy underweight and inadequate increase of gestational weight on fetal growth restriction. Conclusion: Pre-pregnancy underweight and inadequate increase of gestational weight would increase the risk of fetal growth restriction without interaction.

Maternal-Fetal Attachment and Maternal Identity according to Type of Stress Coping Strategies on Immigration Pregnancy Women

PURPOSE

The purpose of this descriptive survey study was designed to identify the stress coping types of married immigrant pregnant women and find out the differences in maternal-fetal attachment and maternal identity based on each types.

METHODS

151 married immigrant women who visited 3 women's hospitals located in J-do for pre-pregnancy checkup were selected as study objects. Data were analyzed by dsecriptive statistics, cluster analysis, t- test, ANOVA, and Scheffe multiple comparison test.

RESULTS

Cluster analysis revealed 4 distinct stress coping styles; low stress-coping involvement social support-oriented type, high stress-coping involvement hopeful thinking type, low stress-coping involvement type, effective stress coping types. Women frequently using effective stress coping type among the four types reported higher maternal-fetal attachment. The group of active coping styles got significantly higher score on maternal identity.

CONCLUSION

Proper stress coping of married immigrant pregnant women regarding pregnancies proved to result in high levels of maternal-fetal attachment and maternal identity. Studies measuring the stress coping styles that affect pregnancies should be continuously conducted.

[Nursing practice in maternity intensive care units. Severe pre-eclampsia in a primigravida]

39 year old woman, pregnant for 31+5 weeks, who came to our intensive care unit (ICU) referred from the emergency department of the hospital, having swollen ankles, headache and fatigue at moderate effort. We proceeded to take blood pressure (158/96 mmHg) and assess lower limb edema. The fetal heart rate monitoring was normal. Knowledgeable and user of healthy guidelines during her pregnancy, she did not follow any treatment. Single mother, she worried about her fetus (achieved through in vitro fertilization), her mother offered to help for any mishap. We developed an Individualized Care Plan. For data collection we used: Rating 14 Virginia Henderson Needs and diagnostic taxonomy NANDA, NOC, NIC. Nursing diagnoses of "fluid volume excess" and "risk of impaired maternal-fetal dyad" were detected, as well as potential complications such as eclampsia and fetal prematurity. Our overall objectives (NOC) were to integrate the woman in the process she faced and that she knew how to recognize the risk factors inherent in her illness. Nursing interventions (NIC) contemplated the awareness and treatment of her illness and the creation of new healthy habits. The work of nursing Maternal ICU allowed women to help maintain maximum maternal and fetal well-being by satisfying any of her needs. Mishandling of the situation leads into a framework of high morbidity and mortality in our units.
