AI Article Synopsis
- Maternal heart rate (HR) influences birth weight and outcomes, with low birth weight being a significant global health issue affecting 15-20% of births.
- The study proposes a new parameter based on maternal and fetal heart rate variability (HRV) to explore its relationship with fetal birth weight, derived from non-invasive electrocardiogram data of 78 pregnant subjects.
- Results indicate that the newly developed parameter shows a significant correlation with gestational age, revealing negative associations with birth weight in certain patterns, underscoring the importance of maternal health in assessing fetal development.
Article Abstract
Maternal heart rate (HR) was reported to affect birth weight and birth outcomes. Low birth weight constitutes a major health problem, and it is estimated that around 15% to 20% of births worldwide are low weight. In our previous study, we discussed the presence of similarities between maternal and fetal HRs, therefore, here, we propose to develop a parameter based on maternal and fetal HR variability (HRV) to divide data into two patterns to investigate the association of fetal birth weight with maternal HR and HRV. The parameter was derived from non-invasive records of maternal and fetal electrocardiograms (ECGs) that were collected from 78 subjects (age: 22 - 44 years old, gestational age (GA): 19 - 40 weeks). The HRV parameter was calculated by first evaluating the standard deviation (SD) of the number of R peaks occurring per 2 seconds (snRpp2s). Then, the difference between maternal and fetal snRpp2s (dmf) was calculated. The correlation between our derived parameter [dmf] with GA revealed a significant correlation that suggested the dmf's association with fetal development. The association analysis results between birthweight with maternal HR and HRV per pattern showed that significant negative correlations exist between them in one pattern. Still, the same correlations were not observed in the other pattern. This study's findings emphasise maternal health's role in fetal development assessment. In addition, this study highlights the importance of developing novel factors for properly assessing fetal development and birth outcomes.

Gluten-free diet during pregnancy and pregnancy outcome: A retrospective cohort study.

Faculty of Medicine and Health Technology, Center for Child, Adolescent, and Maternal Health Research, Tampere University, Tampere, Finland.
Objective: A gluten-free diet (GFD) is becoming increasingly popular, especially among young females, and including those without diagnosed celiac disease (CD). Whether a GFD is appropriate during pregnancy remains unclear. Our primary aim was to evaluate the association of a GFD and neonatal birthweight and incidence of large for gestational age (LGA) and small for gestational age (SGA).

Background: Early identification of developmental delay in children can help in making early intervention for its management. Routine developmental screening is not being practised in India due to lack of trained field workers, lack of awareness among parents and lack of feasible assessment screening tool. There is lack of studies that focuses on home environment provided to the children as it is associated with developmental delay.

Objective: The maternal metabolic environment in early pregnancy can influence fetal growth trajectories. Our objective was to identify interventions initiated in early pregnancy (<20 weeks gestation) in pregnant individuals with risk factors for hyperglycemia and report their impact on primary (neonatal adiposity, small for gestational age, large for gestational age, macrosomia) and secondary outcomes (gestational weight gain, maternal hypertensive disorder, birth injury, NICU admission, preterm delivery, emergency cesarean section).
Data Sources: We searched Cochrane Central database, Medline, Embase, CINAHL databases, and clinicaltrials.

Objective: To investigate the relationship between DNA methylation of cord blood apoptosis genes and low birth weight (LBW).
Methods: A case-control study was conducted on 50 pairs of LBW neonates and normal birth weight. Genome-wide methylation assay was performed using Illumina Human Methylation EPIC microarray to analyze the methylation sites of apoptosis-related genes BCL-2, CASP3, and CASP8.

Background: The impact of direct and indirect drivers on linear growth and wasting in young children is of public health interest. While the contributions of poverty, maternal education, empowerment and birth weight to early childhood growth are well recognized, the contribution of environmental factors like heat, precipitation, agriculture outputs and food security in comparable datasets is less well established.
Objectives: To investigate the association of length-for-age z-score (LAZ) and weight-for-length z-score (WLZ) with various indicators among children under 2 years of age in Pakistan using representative household level nutrition surveys and ecological datasets.
