Maternal Characteristics and Iron Intake as a Factors of Iron Deficiency Anemia among Pregnant Women

Pregnancy is a critical period for fetal growth and development, nutritional issues can significantly affect both maternal and fetal health. This phase is marked by increased nutritional needs to support fetal development and maintain maternal well-being. This study investigates the prevalence and risk factors of iron deficiency anemia among pregnant women in Parung Panjang District Health Center, Indonesia. A cross-sectional study was conducted on 92 pregnant women, examining various maternal characteristics and nutrient adequacy levels. The prevalence of anemia was found to be 36%. Parity emerged as a significant factor, with primipara mothers showing a higher anemia rate (46%) compared to multipara mothers (23.8%). Iron intake adequacy was also significantly associated with anemia status (p = 0.050). Women with insufficient iron intake had a higher rate of anemia (45.7%) compared to those with sufficient intake (26.1%). Other factors such as maternal age, education, and vitamin C intake did not show significant associations with anemia. These findings highlight the importance of targeted interventions for primipara mothers and emphasize the crucial role of adequate iron intake during pregnancy. The study underscores the need for comprehensive anemia prevention strategies in prenatal care.

Individual and community level determinants of minimum meal frequency among breastfeeding children aged 6–23 months in Ethiopia: a multilevel analysis of 2019 Ethiopian Demographic Health Survey data

BackgroundMinimum meal frequency (MMF) is a vital indicator of whether a child’s energy needs are being met. Previous studies in Ethiopia on MMF have primarily focused on individual factors, often using basic logistic regression models with limited scope and small sample sizes. In contrast, this study aims to identify the key determinants of MMF among breastfed children aged 6–23 months in Ethiopia, examining both individual and community-level factors through multilevel logistic regression analysis, utilizing nationally representative data.MethodThe study utilized a community-based cross-sectional design with a sample of 1,245 6–23 month breastfed children in Ethiopia, using data from the 2019 Ethiopian Mini Demographic Health Survey. Mixed effect logistic regression was used to identify factors associated with MMF. Adjusted odds ratios (AOR) with 95% confidence intervals were used to assess variable associations, while Intra-cluster correlation (ICC), median odds ratio (MOR), and proportional change in variance (PCV) were employed to gauge random variation.ResultThe proportion of 6–23-month breastfeeding children with MMF was found to be 55.9% (95% CI: 53.2, 58.6). In mixed effect logistic regression; breastfeeding initiation time within days after birth [AOR = 0.44; 95%CI: (0.24, 0.80)], maternal primary educational level [AOR = 1.46; 95%CI: (1.03, 2.05)], maternal higher level education [AOR = 2.43; 95%CI: (1.22, 4.81)] and children from wealthiest household wealth index [AOR = 2.13; 95%CI: (1.04, 4.33)] were individual-level factors and children from city-based regions [AOR = 1.75; 95%CI: (1.10, 2.77)] was community level factors significantly associated with MMF. The final model indicates that 50.8% of the variation in MMF was explained by combined factors at both individual and community levels and also the variation across clusters remained statistically significant (ICC = 8.1% and variance = 0.29 with p < 0.001).ConclusionMinimum meal frequency is a proxy for meeting energy requirements and it is a key indicator of infant and young child feeding (IYCF) practice. According to this study finding, the prevalence of MMF among 6–23-month children in Ethiopia was found to be low. The study also suggest that time of breastfeeding initiation, women’s educational level, household wealth index, and contextual region were factors significantly associated with MMF. It is recommended that IYCF strategies should be implemented widely through women’s education and empowerment and promoting early initiation of breast feeding to increase the proportion of children to be fed with MMF appropriate for their age.

Exploring and comparing the relationship between maternal anxiety and children's anxiety during admission, hospitalization, and discharge in pediatric wards of Iranian hospitals.

Parental anxiety levels increase during their child's hospitalization. Consequently, anxiety can disrupt parental functioning as a caregiver and potentially transfer distress to the child. This study seeks to explore how maternal anxiety affects the anxiety levels of hospitalized children across three key stages: admission, in-hospital stay, and discharge. A cross-sectional study was conducted with hospitalized children aged 8 to 15 years their mothers. The sample size was determined based on the formula. Data were collected using demographic questionnaires and validated tools, including the State-Trait Anxiety Inventory (STAI) and the Spence Children's Anxiety Scale (SCAS). The STAI measures state and trait anxiety, while the SCAS assesses various domains of child anxiety. Data analysis involved descriptive statistics, Pearson correlation coefficients, and fractional polynomial modeling to assess anxiety trends. The study involved 179 participants, with mothers averaging 36.95 years old. Most participants were homemakers (82.7%) and had less than a high school education (62.6%). The average number of children per mother was 2.02, and only 2.8% utilized assisted reproductive technologies. Maternal anxiety levels were notably high, with mean state anxiety scores decreasing slightly from 45.74 at admission to 44.53 at discharge. Trait anxiety scores followed a similar trend, averaging 42.79 at admission and dropping to 41.60 at discharge. The Spence Children's Anxiety Scale scores were relatively stable, starting at 50.93 at admission and ending at 50.89 at discharge. Severe state anxiety affected 25.7% of participants, while 11.2% experienced severe trait anxiety. Importantly, significant positive correlations were identified between maternal anxiety and children's anxiety throughout the hospitalization period. This study reveals high levels of both maternal and pediatric anxiety throughout hospitalization. Mean scores for state and trait anxiety remained elevated at all stages, with significant correlations between maternal and child anxiety. These results highlight the need for targeted interventions to address and manage anxiety in both mothers and children during hospital stays. Future research should focus on strategies to mitigate these anxieties and improve support for families.

Early pregnancy metal levels in maternal blood and pregnancy outcomes.

Prenatal exposure to heavy metals such as Lead (Pb), arsenic (As), cadmium (Cd), and selenium (Se) is associated with various adverse pregnancy outcomes. This study examines the association between early pregnancy maternal blood levels of these metals and adverse pregnancy outcomes, while also addressing the differences between low-risk and high-risk groups based on having a history of preterm birth (PTB). This prospective cohort study recruited parous women during first trimester, categorized into low-risk and high-risk groups. Participants completed a questionnaire, and heavy metal levels were measured in blood samples. Pregnancy outcomes including PTB, low birth weight (LBW), gestational age at delivery, birth weight and head circumference were recorded following delivery. Multivariable analyses were conducted to evaluate the independent associations between heavy metal levels and pregnancy outcomes, while adjusting for maternal age, BMI, employment, smoking, fertility treatments and education. Among 404 participants, the mean (± SD) levels were Pb: 3.12 ± 1.82µg/L, As: 0.41 ± 0.4µg/L, Cd: 0.26 ± 0.34µg/L, and Se: 119.84 ± 21.05µg/L. Significant differences in Pb, Se, Cd and As levels were observed between the low-risk and high-risk groups, with higher levels in the low-risk group. However, no significant associations were found between heavy metal levels and any of the study outcomes in either univariable comparison or multivariable models. These findings highlight the need for further research to understand the potential impact of these metals on pregnancy, considering population-specific factors and exposure timing.

Maternal Serum SCUBE-1: A Novel Ischemic Marker in Preeclampsia

Background: SCUBE-1 (Signal peptide-CUB (complement C1r/C1s, Uegf, and Bmp1)-EGF (epidermal growth factor)-domain-containing protein 1) is a novel marker of ischemia, which is a cell surface-secreted protein in the platelets and endothelial cells. The aim of the study is to measure serum SCUBE-1 levels and investigate their association with uteroplacental blood flow in patients with preeclampsia. Methods: The study was conducted on patients with preeclampsia. Maternal serum SCUBE1 and IMA levels were the main outcomes. The control group consisted of gestational-age-matched pregnant women. Fetal umbilical artery (UA) pulsatility index (PI), middle cerebral artery PI, cerebroplacental ratio (CPR), and maternal uterine artery (UtA)-PI were also examined, and correlation analysis was performed to reveal the association between maternal serum SCUBE1 levels and Doppler findings. Results: The study group consisted of thirty-two preeclamptic patients, and the control group consisted of thirty-two uncomplicated singleton pregnancies. Maternal serum SCUBE1 and IMA levels were significantly higher in preeclamptic women compared to the control group (p < 0.000, p < 0.004, respectively). Mean UtA-PI values and fetal UA-PI values were significantly higher in preeclamptic pregnant women compared to the control group (p < 0.05, p < 0.05, respectively). However, the average CPR was significantly lower in pregnant women with preeclampsia (p < 0.05). While no significant correlation was found between maternal serum SCUBE1 levels and UA-PI and CPR (p > 0.05, p > 0.05, respectively), a significant correlation was found between right and left UtA-PI (p < 0.004, p < 0.006, respectively). Conclusions: The maternal serum SCUBE1 level is increased in patients with preeclampsia, and this increase is significantly correlated with the maternal uterine artery pulsatility index.

Insights into the pathogenesis of gestational and hepatic diseases: the impact of ferroptosis

Ferroptosis, a distinct form of non-apoptotic cell death characterized by iron dependency and lipid peroxidation, is increasingly linked to various pathological conditions in pregnancy and liver diseases. It plays a critical role throughout pregnancy, influencing processes such as embryogenesis, implantation, and the maintenance of gestation. A growing body of evidence indicates that disruptions in these processes can precipitate pregnancy-related disorders, including pre-eclampsia (PE), gestational diabetes mellitus (GDM), and intrahepatic cholestasis of pregnancy (ICP). Notably, while ICP is primarily associated with elevated maternal serum bile acid levels, its precise etiology remains elusive. Oxidative stress induced by bile acid accumulation is believed to be a significant factor in ICP pathogenesis. Similarly, the liver’s susceptibility to oxidative damage underscores the importance of lipid metabolism dysregulation and impaired iron homeostasis in the progression of liver diseases such as alcoholic liver disease (ALD), non-alcoholic fatty liver disease (NAFLD), cholestatic liver injury, autoimmune hepatitis (AIH), acute liver injury, viral hepatitis, liver fibrosis, and hepatocellular carcinoma (HCC). This review discusses the shared signaling mechanisms of ferroptosis in gestational and hepatic diseases, and explores recent advances in understanding the mechanisms of ferroptosis and its potential role in the pathogenesis of gestational and hepatic disorders, with the aim of identifying viable therapeutic targets.

Exposure to and Transplacental Transfer of Per- and Polyfluoroalkyl Substances in a Twin Pregnancy Cohort in Korea.

Twin pregnancies involving assisted reproductive technology, particularly among older women, are considered to be high risk and vulnerable to chemical exposures. Per- and polyfluoroalkyl substances (PFAS) can cross the placenta and affect the fetus, but their transplacental transfer (TPT) is not well characterized for twin pregnancies. We employed a subset of twin pregnancies from the Ideal Breast Milk (IBM) cohort and measured the levels of PFAS and related chemicals in maternal (n = 78) and cord serum (n = 156) samples. L-PFOS and PFOA were detected at higher levels in maternal serum, with geometric means of 4.22 and 2.80 ng/mL, respectively, while the level of Br-PFHxS was higher in cord serum (0.29 ng/mL). Higher maternal PFAS levels were associated with the occurrence of maternal vascular malperfusion. Greater differences in cord PFAS levels between twin newborns were associated with higher maternal PFAS levels and an asymmetrical placental perfusion. The TPT ratio exhibited a U-shaped pattern with the number of carbons of PFAS, similar to a singleton pregnancy. Moreover, those with eight carbon atoms, i.e., 9Cl-PF3ONS, PFOA, and PFOS, showed different TPT efficiencies with respect to their structure and functional group. While the twin pregnancy does not appear to influence exposure levels or TPT efficiencies of PFAS and related chemicals, the consequences of the exposure warrant further investigations in this population.

Association of maternal 25(OH)D levels during pregnancy with fetal birth weight and preschooler growth status: A retrospective birth cohort study.

There is limited and conflicting evidence available regarding the correlation between maternal vitamin D status and childhood overweight and body mass index (BMI). The aim of this study was to investigate the following: (1) potential association between maternal 25-hydroxyvitamin D (25(OH)D) levels and newborn growth status; (2) relationship between maternal 25OHD levels and BMI and the risk of overweight with preschoolers being overweight. A cohort of 3213 eligible singleton mother-infant pairs were used to investigate the possible associations between maternal 25(OH)D levels and fetal growth status. Data of 1767 available singleton mother-infant pairs and 6-year-old preschoolers was applied to analyze the potential correlations between maternal 25(OH)D status and risk of childhood overweight. Compared with sufficient 25(OH)D in pregnancy group (≥75 nmol/L), there were no correlations between the maternal 25(OH)D deficiency (<50 nmol/L) and large gestational age (LGA) (p = 0.465), small gestational age (SGA) (p = 0.607), lower birth weight (LBW) (p = 0.725) or fetal macrosomia (p = 0.535). Moreover, no significant associations between insufficient maternal 25(OH)D (50-75 nmol/L) and LGA (p = 0.505), SGA (p = 0.816), LBW (p = 0.816), or fetal macrosomia (p = 0.413) were observed. We found statistically significant disparities between the fetal birth weight and height (p < 0.001), weight (p < 0.001), head circumference (p = 0.001) of 6-years preschooler. No significant associations were found between the maternal 25(OH)D levels and BMI and risk of overweight at 6-year-old preschoolers. There were no apparent correlation found between maternal 25(OH)D concentrations and fetal birth status. There was no evidence found to suggest the effect of maternal 25(OH)D level on overweight at 6-year-old preschoolers.

The impact of NICU client-centered, written, and visual reporting on maternal stress and attachment post-infant heart surgery

BackgroundIn this study, we explored the impact of client-centered, written and visual reporting based on the Newborn Individualized Care and Assessment Program (NIDCAP) approach on stress levels and attachment among mothers with neonates hospitalized in Neonatal Intensive Care Unit following open heart surgery. MethodsThe clinical trial involved 70 mothers with an infant in the neonatal intensive care unit following heart surgery at Children's Medical Center in Tehran. Eligible participants were randomly assigned to either the control group (35 mothers) or the intervention group (35 mothers). While the control group adhered to regular daily visits to their sick infant as part of the hospital routine, the intervention group in addition to these visits, received daily written and visual reports, based on the NIDCAP approach standards for a week through WhatsApp messenger. Maternal Stress levels and attachment were assessed on the 7th day and again two weeks post-intervention. Data analysis was conducted using SPSS software. ResultsThe intervention group experienced a significant reduction in stress levels. Mean stress levels decreased from 102.57 ± 30.8 to 72.25 ± 15.81 on the day 7th. Two weeks post-intervention, the average stress level further decreased to 62.08 ± 15.00(p < 0.05). Interestingly there was a slight increase in attachment score in the intervention group after one week. However, at the end of the study, there was no significant difference between the intervention and control groups. ConclusionClient-centered reporting based on the NIDCAP approach could substantially reduce stress levels among mothers with hospitalized newborns in neonatal cardiac surgery units. Especially when the constant presence of parents at the newborn's bedside is not possible, this approach could be considered a practical, innovative, and effective method to reduce maternal stress levels in the NICUs after heart surgery.

Associations of maternal serum ferritin levels across gestation with gestational diabetes mellitus: A longitudinal cohort study.

The longitudinal changes in maternal serum ferritin (SF) levels across gestation, which indirectly reflect iron supplementation, have not been extensively investigated in relation to gestational diabetes mellitus (GDM). We conducted a retrospective cohort study at a tertiary maternal hospital in Shanghai. Women with SF concentration measurements at 8.0-13.6 weeks' gestation (GW), 29.0-31.6 GW, and an oral glucose tolerance test (OGTT) at 24-28 GW were included. We utilized logistic regression analysis to assess GDM association with maternal SF levels and longitudinal changes. The study included 17 560 women, with 2160 (12.3%) participants diagnosed with GDM. Adjusted odds ratios (ORs) (95% confidence intervals [CIs]) for GDM across increasing quartiles of SF concentrations at 8.0-13.6 GW were 1.00 (reference), 1.139 (95% CI: 1.012-1.283), 1.093 (95% CI: 0.969-1.233), and 1.248 (95% CI: 1.111-1.403). Similarly, at 29.0-31.6 GW, increasing quartiles of SF concentrations were associated with higher adjusted ORs for GDM: 1.00 (reference), 1.165 (95% CI: 1.029-1.320), 1.335 (95% CI: 1.184-1.505), and 1.428 (95% CI: 1.268-1.607). Pregnant women with higher SF levels (upper 25th percentile) at 8.0-13.6 GW had a reduced GDM risk if their SF levels decreased to the lower 25th percentile at 29.0-31.6 GW. Conversely, the subgroup with higher SF levels (upper 25th percentile) at both time points had the highest incidence rate of GDM (15.3%, 1.235 [95% CI: 1.087-1.404]). Maternal SF levels independently and positively associated with GDM risk during early and late gestational stages. Considering the increased GDM risk, routine iron supplementation for iron-replete women is questionable.

Maternal and Cord Blood Levels of Metals and Fetal Liver Function

Exposure to metals during pregnancy has been associated with adverse birth outcomes, but its impact on fetal liver function remains poorly understood. This study for the first time aimed to investigate the association between maternal and umbilical cord blood Metals levels and umbilical liver enzymes. A comprehensive analysis was conducted on 450 mother-newborn pairs in 2022, measuring 13 Metals in serum samples from pregnant women during the third trimester and umbilical cord blood samples. Regression analyses were utilized to examine the relationship between levels of maternal and umbilical cord blood Metals and the levels of gamma-glutamyl transferase (GGT), umbilical alkaline phosphatase (ALP), alanine aminotransferase (ALT), and aspartate aminotransferase (AST). G-comp analyses evaluated the combined effect of metals exposure on umbilical liver enzymes. Elevated levels of certain Metals in cord blood and maternal samples were positively linked with increased umbilical GGT, ALP, ALT, and AST levels. Notably, zinc (Zn) levels in cord blood exhibited an inverse correlation with umbilical liver enzyme levels. Furthermore, g-comp analyses revealed significant positive associations between exposure to metals mixtures and umbilical liver enzyme levels. An increase of one quartile in the mixture of maternal and umbilical Metals was linked with 99.45 U/L (95% CI:37.72, 161.19, p < 0.01), 2.79 (95% CI: 0.92, 4.65, p < 0.01), and 87.17 (95% CI: 53.96, 120.38, p < 0.01) increase in ALP, ALT and GGT levels. Further examination of the weight of Metals revealed As, Cd, Ni, Pb, Hg and Cr with the highest positive effects and Zn with the highest negative effect in the mixture effect on the umbilical liver enzyme. In summary, our results underscore the potential influence of prenatal heavy metal exposure on fetal liver function.

The Impact of Gestational Diabetes Mellitus on Minipuberty in Girls.

Minipuberty is the second phase of physiological activation of the reproductive axis, playing a role in the postnatal development of sexual organs. The course of female minipuberty was found to be affected by low maternal vitamin D status and hypothyroidism during pregnancy. The aim of the current study was to assess the hormonal profile and the size of sexual organs in daughters of mothers with gestational diabetes mellitus. The study included three matched groups of infant girls: daughters of healthy women without metabolic disorders during pregnancy (group 1), daughters of women with poorly controlled gestational diabetes mellitus (group 2), and daughters of women with gestational diabetes mellitus adequately controlled during pregnancy (group 3). Urinary levels of gonadotropins, salivary levels of estradiol, testosterone, DHEA-S and progesterone, ovarian volume, uterine length and breast diameter were measured from postnatal month 1 to postnatal month 18. Concentrations of FSH, LH and estradiol were higher, while concentration of progesterone was lower in group 2 than in the remaining groups. There were no between-group differences in concentrations of testosterone and DHEA-S. Levels of LH, FSH, estradiol and progesterone correlated with maternal whole-blood levels of glycated hemoglobin. Group 2 was also characterized by the longest detection periods for LH and estradiol. Ovarian volume, uterine length and breast diameter were greater in group 1 than in the remaining two groups. Over the entire observation period, there were no differences in hormone levels and sizes of the sexual organs between groups 1 and 3. The obtained results suggest that poorly controlled, but not well controlled, gestational diabetes mellitus affects the course of female minipuberty.

Analysis of the relationship between neonatal birth weight and meconium metabolites based on birth cohort metabolomics

Neonatal birth weight is a crucial indicator of intrauterine growth and development with important implications for child development and adult health. The birth weight of a newborn is closely linked to the nutrition and health of the mother during pregnancy as well as genetic factors. Therefore, assessing the metabolic status of the fetus in utero is greatly significant for understanding the mechanisms responsible for abnormal birth weight. While previous studies often analyzed the impact of maternal metabolism on fetal development using umbilical cord blood from pregnant women, such blood may not accurately reflect the actual intrauterine environment owing to the barrier function of the placenta; moreover, obtaining biological samples during the fetal period is challenging. Meconium, the first feces excreted by a newborn, provides ideal biological material for studying maternal and infant health. Metabolomics can reveal metabolic changes in living organisms by analyzing small molecules in biological samples; hence studying meconium samples using metabolomics technology is expected to reveal fetal metabolic changes during pregnancy, thereby providing new insights into fetal nutritional intake, growth, and development, as well as metabolic pathways related to birth weight. To gain a deeper understanding of the metabolic changes associated with birth weight, this study collected metabolomic data from the meconium of 484 newborns in the established Xiaogan birth cohort using an untargeted metabolomics technique based on liquid chromatography-high resolution mass spectrometry (LC-HRMS) and analyzed the association between meconium metabolites and birth weight. This cohort exhibited incidence rates of low birth weight (<2500 g) and macrosomia (>4000 g) of 3.3% and 7.2%, respectively, which were roughly equivalent to the national average. Orthogonal partial least squares discriminant analysis revealed significant differences between the meconium metabolomes of the low birth weight and macrosomic groups when compared to the normal weight group. We discovered significant distinctions between the differential metabolites of newborns of low birth weight and those of normal weight, as well as between macrosomic and normal weight newborns that point to disparate biological pathways. Newborns with low birth weight exhibited significantly lower levels of critical amino acids, such as glutamate and proline, compared to the normal weight group, which may be associated with placental dysfunction and maternal nutritional deficiencies. Conversely, the meconium of macrosomic newborns contained significantly elevated levels of hormone metabolites such as estrone that reflected the pathophysiological state associated with maternal metabolic diseases or excessive placental hormone levels. Our study suggests that the metabolomic profile of the meconium reflects the metabolic pathways and regulatory mechanisms at play during fetal growth and development, and offers potential metabolic biomarkers and directions for future in-depth research into diseases related to fetal development. However, this study was based solely on the Xiaogan birth cohort, which was limited to specific regions and populations. A multicenter, multiethnic, and multiregional study is expected to help validate the universality of our research findings.

Studies of Lipid Profiles Among Infants with Respiratory Distress Syndrome

Background: Respiratory distress syndrome (RDS) is known as hyaline membrane disease (HMD). It is the major cause of neonatal respiratory distress, especially in preterm infants Infants with RDS present with tachapnea, cyanosis, grunting, subcostal and intercostal retractions and nasal flaring. Oliguria with mild generalized edema may be present. Oxygen requirement may increase rapidly and is typically higher than that seen in infant with transient tachapnea of the newborn (TTN). Objective: to evaluate the relationship between the maternal and cord blood lipid profiles in preterm babies with respiratory distress syndrome. Methods: This is a case control study which was conducted on 50 preterm neonates admitted to the neonatal intensive care unit of Shebin El-Kom teaching hospital between January 2020 and October 2021. Results: the mean of total cholesterol was significantly higher in infants whose mothers had received antenatal steroid for lung maturity than those whose mothers had not (P&lt;0.05). But there was no significant difference in the mean of levels of TG, HDL-cholesterol, LDL-cholesterol and VLDL cholesterol between both groups. Also, There is a positive correlation between weight gain during pregnancy and neonatal cord blood levels of (Total cholesterol, TG, HDL-C, LDL-C and VLDL-C), There is a positive correlation between maternal blood levels of (total cholesterol, TG, LDL-C and VLDL-C) and their neonatal cord blood levels of (total cholesterol, TG, HDL-C, LDL-C and VLDL-C), There is a positive correlation between the maternal blood level of HDL-C and their neonatal cord blood levels of (total cholesterol and HDL-C).also, the cutoff values of cord blood (total Cholesterol, HDL-C, and LDL-C) below which RDS can be predicted are 80, 45.5 and 23.2 mg/dl respectively with a sensitivity of 83.3%, 86.7% and86.7% and with specificity of 95%, 80% and 70% respectively. Conclusion: RDS is accompanied with lipid alteration in the infants and their mothers. The results of this study point to the importance of measuring maternal serum and cord blood lipid profile as a predictor for the occurrence of RDS.

Effect of Combination of Facial Acupuncture Therapy with Lavender Aromatherapy on Reducing Postpartum Maternal Anxiety Levels in Medan Tuntungan District

Following childbirth, moms will undergo emotional fluctuations characterized by mood swings, anxiety, dizziness, and feelings of despair. Impaired maternal understanding of infant care can lead to psychological issues that impact the mother's physical well-being, including disrupted sleep patterns and reduced appetite. Failure to promptly manage anxiety in postpartum mothers can lead to the development of baby blues syndrome and postpartum depression. This study employs a Quasi Experiment design with a pre-posttest not include a control group to quantitatively investigate the impact of combining facial acupressure therapy with lavender aromatherapy on anxiety reduction in postpartum mothers. The investigation was conducted in Medan Tuntungan District, located in Medan City. One hundred postpartum women constituted the sample in this study. The data collection process involved administering treatment (facial acupressure therapy with lavender aromatherapy), followed by observation and interviews conducted using the HARS instrument. The analysis conducted using the Wilcoxon Signed Ranks Test revealed a negative ranks value of 94. This indicates that out of the 100 postpartum women who participated in the study, 94 mothers reported a reduction in anxiety levels. The positive rankings index is 0, indicating that none of the 100 postpartum moms who participated in the study reported a rise in anxiety levels. The tie value of 6 indicates that among the 100 postpartum moms who participated in the study, 6 mothers did not show any significant difference in anxiety levels before and after undergoing a combination of Facial Acupressure Therapy with Lavender Aromatherapy. Moreover, it is established that the significance value at this stage of analysis is 0.000 or greater than ? (0.05). Therefore, it can be inferred that there is a significant impact of the combination of Facial Acupressure Therapy with Lavender Aromatherapy on the reduction of anxiety levels in postpartum mothers.

Investigating the impact of severe maternal SARS-CoV-2 infection on infant DNA methylation and neurodevelopment.

Maternal infections during pregnancy can increase the risk to offspring of developing a neurodevelopmental disorder. Given the global prevalence and severity of infection with Severe Acute Respiratory Syndrome related Coronavirus 2 (SARS-CoV-2), the objective of this study was to determine if in utero exposure to severe maternal SARS-CoV-2 infection alters infant neurodevelopmental outcomes at 12 months and to identify potential biological markers of adverse infant outcomes. Mother-infant dyads exposed to severe SARS-CoV-2 infection (requiring hospitalization) during pregnancy and age and sociodemographic matched control dyads were recruited from Monash Medical Centre, Australia in 2021/22 and prospectively assessed over 12 months. Maternal serum cytokine levels and Edinburgh Postnatal Depression Scale (EPDS) scores were assessed at birth. DNA methylation was assessed from infant buccal swabs at birth (Illumina EPIC BeadChip). Infant neurodevelopmental outcomes at 12 months were assessed using the Ages and Stages Questionnaire (ASQ-3). Mothers exposed to severe SARS-CoV-2 exhibited elevated serum IL-6 and IL-17A and higher EPDS scores than controls at birth. Infants exposed to severe SARS-CoV-2 in utero demonstrated over 3000 significant differentially methylated sites within their genomes compared to non-exposed (adjusted p-value < 0.05), including genes highly relevant to ASD and synaptic pathways. At 12 months, severe SARS-CoV-2 exposed infants scored lower on the ASQ-3 than non-exposed infants, and communication and problem-solving scores negatively correlated with maternal IL-6 levels at birth. DNA methylation changes therefore unveil potential mechanisms linking infection exposure to delayed neurodevelopment and maternal serum IL-6 levels may be a potential biomarker of child developmental delay. Mothers exposed to severe SARS-CoV-2 infections show elevated pro-inflammatory cytokines. Infants exposed in utero to severe SARS-CoV-2 infection show altered DNA methylation at birth and delayed development at 12 months of age. Created in Biorender.com.

The impact of maternal serum biomarkers on maternal and neonatal outcomes in twin pregnancies: a retrospective cohort study conducted at a tertiary hospital.

Prior prediction models used for screening preeclampsia (PE) in twin pregnancies were found to be inadequate. In singleton pregnancies, various maternal biomarkers have been shown to be correlated with negative pregnancy outcomes. However, the impact of these biomarkers in twin pregnancies remained uncertain. A retrospective cohort study was carried out on 736 twin pregnancies at a tertiary hospital in Hangzhou, China. Multivariable logistic models were employed to examine the association between levels of serological markers and the likelihood of adverse pregnancy outcomes. The final logistic model was formulated as a user-friendly nomogram. The primary outcome assessed was the occurrence of PE. Results were presented as odds ratios (ORs) with corresponding 95% confidence intervals (CIs). The prevalence of PE in the study was 10.3%. When comparing women diagnosed with PE to those without, it was evident that the former group experienced a significantly higher risk of unfavorable maternal and neonatal outcomes. A multivariable logistic regression analysis revealed notable associations between various factors including maternal age, parity, gestational weight gain, a family history of hypertension, as well as levels of cholesterol, albumin, and creatinine and the risk of developing PE, with a significance level of P < 0.05. The concordance index for the constructed nomogram was determined to be 0.792 (95% CI: [0.739-0.844]). Furthermore, an increment of 1 * 1012/L in red blood cell (RBC) count was associated with more than a two-fold increase in the odds of experiencing adverse maternal outcomes (OR 2.247, 95% CI: [1.229-4.107]). However, no significant correlations were identified between any of the examined variables and neonatal outcomes. In this study, we developed a user-friendly predictive model that achieves notable detection rates by incorporating maternal serum biomarker levels alongside maternal characteristics and medical history. Our findings indicate that the probability of adverse maternal outcomes increases with elevated levels of RBCs. Obstetricians should consider intensifying surveillance for these women in clinical practice.

Housing tenure and acute lower respiratory tract infection admissions in two Scottish birth cohorts

Abstract Introduction Early-life acute lower respiratory tract infections (LRTI) have been associated with increased morbidity and mortality. Despite young children spending much of their time at home, the contribution of home ownership status, on LRTI hospital admissions is unknown. Objectives To estimate the association between housing tenure and the odds of LRTI hospitalization in children &amp;lt;2 years in two birth cohorts. Methods De-identified Scottish birth records were linked to maternal Census data (2001 and 2011) and to hospital admission data to construct two birth cohorts (Cohort 1 (C1), born 2000-2002; Cohort 2 (C2), 2010-2012). Using logistic regression we estimated the association of housing tenure (owned, social rented, private rented, rent-free) with the odds of LRTI hospital admission, before and after adjustment for maternal age, residential area, and maternal qualification level. Results Over the 2-year follow-up, there were 14,833 LRTI admissions in 12,527 children (10,832 children had 1 LRTI admission and 1,695 &amp;gt;1 LRTI admission). 75.6 % of all LRTI admissions were due to bronchiolitis. In C1 and C2, 4.0% and 5.3% children, respectively, had one or more LRTI admission. Compared to children living in owned housing, the odds of LRTI admission were higher in children living in social rented housing (C1: Odds ratio=1.40, 95% confidence interval: 1.31-1.49; C2: 1.23, 1.16-1.31), private rented (C1:1.24, 1.11,1.39; C2: 1.14, 1.06-1.21), and rent-free housing (C1: 1.53, 1.35,1.74; C2: 1.04, 0.80-1.36) after confounder adjustment. Conclusions We found an association between non-owned housing and higher odds of LRTI admission which was more marked in C1 than in C2. Further research is warranted to unpick the mechanisms underlying the association between housing tenure and LRTI admission. Interventions to prevent LRTI admissions could usefully target children living in non-owned housing. Key messages • This study demonstrates the value of administrative and health data linkage in improving our understanding of how socio-environmental factors might impact children’s respiratory health. • Children living in social and private rented housing (compared to owned housing) have a higher risk of LRTI hospital admission and could benefit the most from LRTI-lowering interventions.

Associations between gestational exposure to perfluoroalkyl substances, fetal growth, and the mediation effect of thyroid hormones

Prenatal exposure to perfluoroalkyl and polyfluoroalkyl substances (PFASs) may cause adverse birth outcomes. Thyroid hormones may play a key role in mediating the effects of PFAS. We enrolled 374 mother-infant pairs from the Ezhou birth cohort study between 2019 and 2020. Eight PFASs and six thyroid hormones were measured in maternal serum during the first trimester of pregnancy. Neonatal growth metrics, including birth weight, length, head circumference, and gestational age, were acquired. Multivariate linear regression was performed to determine the associations between maternal serum PFAS and thyroid hormone levels and birth outcomes and a mediation analysis was also conducted. Except for perfluoroheptanoic acid (41.2%), the other seven PFAS detection rates were more than 85%, and the highest median concentration was observed for PFOSA with levels of 5.21 ng/mL. After controlling for typical confounders, we observed a decrease in birth length (cm) with increasing serum concentrations of perfluorononanoic acid (PFNA) (β = -0.54; 95% CI = -1.0, -0.08) and perfluorohexane sulfonate (PFHxS) (β = -0.64; 95% CI = -0.86, -0.42). Additionally, a decrease in birth head circumference was observed with increasing concentrations of perfluorooctanote (PFOA) (β = -0.73, 95% CI = -1.19, -0.27) and PFHxS (β = -0.30; 95% CI = -0.53, -0.07). Maternal free triiodothyronine (FT3) mediated 36.7% of the negative association between PFNA and birth length, and free thyroxine (FT4) mediated 30.8% of the effect of PFOA on head circumference. When performing stratified analysis by infant sex, the associations might differ between boys and girls. Our study suggested prenatal exposure to some PFASs was negatively associated with birth length and circumference, and FT3 and FT4 may partly mediate the association.
