Prevalence of Pregnancy-Induced Hypertension in Teenage Pregnancies at a Tertiary Care Hospital

The aim of this study was the evaluation of the prevalence of pregnancy-induced hypertension among teenage pregnancies in a tertiary care setup. This descriptive case series was conducted at the Gynaecology & Obstetrics Department from December 2023 to June 2024. A total of 163 pregnant women in the age range of 10-19 years with a gestation age of more than 20 weeks were enrolled in the study. PIH was diagnosed if blood pressure was ≥140/90 mmHg on at least two occasions. The participants were followed at different stages of pregnancy. Data analysis was done using SPSS-17 and Chi-square tests, where a p-value ≤0.05 was considered significant. PIH was present in 14.7% of cases. No significant association was noted between maternal age, gravidity, parity, and gestational age with PIH. Younger maternal age is the other important risk factor for PIH.

Maternal Obesity and Differences in Child Urine Metabolome

Background/objective: Approximately one-third of pregnant individuals in the U.S. are affected by obesity, which can adversely impact the in utero environment and offspring. This study aimed to investigate the differences in urine metabolomics between children exposed and unexposed to maternal obesity. Methods: In a study nested within a larger pregnancy cohort of women–offspring pairs, we measured untargeted metabolomics using liquid chromatography–mass spectrometry in urine samples from 68 children at 4–8 years of age. We compared metabolite levels between offspring exposed to maternal obesity (body mass index [BMI] ≥ 30.0 kg/m2) vs. unexposed (maternal BMI 18.5–24.9 kg/m2) and matched them on covariates, using two-sample t-tests, with additional sensitivity analyses based on children’s BMI. This study reports statistically significant results (p ≤ 0.05) and potentially noteworthy findings (fold change > 1 or 0.05 < p < 0.15), considering compounds’ involvement in common pathways or similar biochemical families. Results: The mean (SD) maternal age at study enrollment was 28.0 (6.3) years, the mean child age was 6.6 (0.8) years, 56% of children were male, and 38% of children had a BMI in the overweight/obese range (BMI ≥ 85th percentile). Children exposed to maternal obesity had lower levels of 5-hydroxyindole sulfate and 7-hydroxyindole sulfate and higher levels of secondary bile acids. Phenylacetic acid derivatives were lower in offspring exposed to obesity and in offspring who had a current BMI in the overweight/obese range. Exposure to maternal obesity was associated with lower levels of androgenic steroid dehydroepiandrosterone sulfate (DHEA-S). Conclusions: In this preliminary study, children exposed to maternal obesity in utero had differences in microbiome-related metabolites in urine suggestive of altered microbial catabolism of tryptophan and acetylated peptides. Some of these differences were partially attributable to the offspring’s current BMI status. This study highlights the potential of urine metabolomics to identify biomarkers and pathways impacted by in utero exposure to maternal obesity.

The Relationship Between Maternal Education Level and Stunting: Literature Review

Children who are shorter than their peers due to malnutrition before and after birth are called stunting. Stunting occurs when a married adolescent woman has a low socioeconomic status and education level, thus increasing psychological stress caused by limited human resources and childcare so that child growth and development are not optimal. One important factor that influences the prevalence of stunting in early childhood and toddlers is maternal education. Increasing public awareness of the importance of maternal education in preventing stunting and improving the quality of child health. This review study aims to present evidence on the correlation between stunting and maternal education and to determine the extent to which maternal education affects the nutritional status and growth of children, especially stunting. With these objectives, this study is expected to make a significant contribution to understanding and addressing stunting problems in the community. The literature review method and the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) meta-analysis process were used throughout the investigation. There is a correlation between stunting and maternal education based on many research findings. In conclusion, education level, low maternal age, poor toddler care and nutritional intake during pregnancy are associated with stunting

The Analysis of the Fetal Abdominal Wall and Gastrointestinal Tract Abnormalities in a Single Tertiary Center

OBJECTIVE: We aimed to evaluate the fetuses with gastrointestinal anomalies and anterior abdominal wall defects detected in the prenatal period in our clinic and to analyze their perinatal outcomes. STUDY DESIGN: This retrospective study analyzed the data of 67 cases evaluated by the perinatology department of the Basaksehir Cam and Sakura City Hospital between January 2021 and May 2023 with a diagnosis of fetal anterior abdominal wall and gastrointestinal tract abnormalities. RESULTS: A total of 67 cases were included in our study with a mean maternal age of 26.4 ± 3.1 years and a median gestational week of first assessment at our center of 22 weeks (12-39 weeks). The most common anterior abdominal wall malformations were omphalocele (n=29, 43.3%) and gastroschisis (6 cases, 9.0%), and the most common fetal gastrointestinal tract anomalies were duodenal atresia (n=10, 14.9%), dilated bowel (n=5, 7.4%), and intestinal atresia (n=4, 5.9%). While genetic testing was carried out in 18 cases (27%), chromosomal abnormality was found in 6 (9.0%) cases. Termination of pregnancy was performed in 6 cases (9.0%). Postnatally, surgery was performed in 49 cases (73.1%) with a diagnosis of postpartum omphalocele, duodenal atresia, gastroschisis, intestinal and anal atresia. An uneventful surgical course was recorded for 47 cases that underwent surgery. CONCLUSION: The most common abdominal wall defects are omphalocele and gastroschisis, and the most frequent gastrointestinal anomalies are small bowel abnormalities (duodenal atresia, dilated bowel, intestinal atresia) in our study cohort. These abnormalities might be an isolated anomaly or part of a syndrome or associated with chromosomal abnormalities. The prognosis for infants with gastrointestinal malformation depends on the presence of associated anomalies or karyotype anomalies.

Analysis of chromosome test results of 24,175 miscarried fetuses in Japan from 2000 to 2021.

Fetal chromosome abnormalities, the most common cause of spontaneous abortion, were investigated pre-1980s. In recent years, chromosome testing has been outsourced to testing companies in Japan, and there have been few epidemiological studies of chromosome testing of miscarried fetuses on a nationwide scale. We analyzed the chromosome test data of SRL, Inc., one of the largest clinical laboratories that has collected tissue specimens of products of conception derived from miscarried fetuses from hospitals throughout Japan from 2000. We collected and analyzed 24,175 cases, among which 8,726 (36.1%) were normal chromosomes, 1,298 (5.4%) were sex chromosome abnormalities, 9,735 (40.3%) were autosomal trisomies, 73 (0.3%) were autosomal monosomies, 840 (3.5%) were ploidy, 512 (2.1%) were chromosome structural abnormalities, and 2,991 (12.4%) were mosaics. The frequency of autosomal trisomy increased at the older maternal ages. By chromosome number, trisomies 22, 16, 21, and 15 were associated with advanced maternal age, but trisomies 13, 14, and 18 were not associated with advanced maternal age. The presence or absence of this maternal age effect was correlated with the chromosome segregation being due to maternal meiosis I or meiosis II. For the sex ratios of the fetuses, we focused on trisomies 22, 21, 18, 16, 15, 14, and 13, and found that only trisomy 16 was significantly more frequently seen in female fetuses. The findings of this study provide insights into the basic understanding of miscarriage and will be useful in counseling and medical education.

Mild Ovarian Stimulation Using the Aromatase Inhibitor Letrozole (LTZ) is a Good Stimulation Protocol for to Obtain Euploid Blastocysts for Advanced Maternal Age Women

Purpose: Mild Ovarian Stimulation (MOS) is an effective form of Assisted Reproductive Technology (ART) for Advanced Maternal Age (AMA) women. Taking either Clomiphene (CC) or Letrozole (LTZ) with MOS reduces the amount of gonadotropin that must be used. It has remained uncertain, however, whether LTZ or CC is more effective in combination with MOS. Therefore, we evaluated the choice of combination of either CC or LTZ with MOS and quantified the obtainment of euploid blastocysts for AMA women. Methods: This retrospective study was conducted between January 2020 and April 2021. In this study, we stimulated 286 women with MOS, 153 of these women used CC (CC group) and 133 were given LTZ (LTZ group). All women took either 100 mg of CC or 5 mg of LTZ daily for 7 days between MC 3 and MC 9, and 225 IU of recombinant-FSH were administered on MC 3, MC 5, MC 7, and MC 9. The euploid rates were compared between these two groups. Among them, the women who were ≥ 40 years old were divided into two groups, the CC-O40 group (n = 61) and LTZ-O40 group (n = 54), and the euploid rates were evaluated. Results: For AMA women, the blastocyst formation rate in the LTZ-O40 group (58.5%) was significantly higher than that in the CC-O40 group (46.6%, p < 0.05). The euploid rate in the LTZ group was 53.4%, which was significantly higher than that in the CC group (38.0%, p < 0.05). The AMA euploid rate in the LTZ-O40 group was 40.5%, which also was significantly higher than that in the CC-O40 group (16.7%, p < 0.05). Conclusions: For AMA women, a regimen of LTZ combined with MOS is the most effective ovarian stimulation method for obtaining euploid blastocysts.

Molar Incisor Hypomineralization: Etiology, Correlation with Tooth Number Anomalies and Implications for Comprehensive Management Strategies in Children from Transylvania.

This study investigates the etiology of enamel developmental defects, specifically Molar Incisor Hypomineralization (MIH), and explores correlations between MIH and dental anomalies such as hypodontia to improve interdisciplinary restorative and orthodontic treatments. Additionally, it assesses the influence of stress factors on the development of enamel defects. Conducted from July to September 2024, this study involved 57 patients aged 6 to 11 from an urban setting, divided into two groups: 32 with MIH and 25 controls, selected based on criteria of mixed dentition without systemic pathology or chronic medication. Clinical evaluations, including intraoral photographs and panoramic radiographs, were performed alongside a detailed questionnaire addressed to the mothers covering prenatal, perinatal, and postnatal factors. The average age of children with MIH was 7.5 years, in contrast to 7.04 years in the control group (p = 0.17). Significant differences were noted in maternal age, with MIH mothers older (35.56 years) than controls (29.36, p = 0.0001). The prevalence of MIH was higher in boys (66.7%) compared to girls (38.1%, p = 0.036). Factors such as prolonged labor, medication during birth, and early postnatal medication were significantly linked to MIH. The study shows a strong correlation with hypodontia, with a significantly higher incidence of tooth number anomalies (p = 0.009) in the study group. Overall, the study emphasizes the association of MIH with various maternal and birth-related factors and with hypodontia, highlighting the need for a comprehensive, multidisciplinary approach to diagnosis and treatment. Further research is recommended to investigate the relationship between stress factors and MIH.

Maternal childhood trauma, caregiving behavior, and child cognitive development in the context of drug addiction.

Exposure to childhood trauma confers intergenerational risk on child development. However, the mechanism linking a mother's childhood trauma with her child's cognitive development remains poorly understood. This study recruited 71 mother-child dyads affected by substance use disorder from local, community-based, outpatient substance use treatment programs. Maternal exposure to childhood trauma, caregiving behavior, and child cognitive development were assessed in each mother-child dyad. These were measured through a comprehensive biopsychosocial interview, an observed dyadic interaction coded using the Coding Interactive Behavior system, and the Bayley Scales of Infant and Toddler Development, Screening Test, respectively. We hypothesized that compromised caregiving behavior would mediate a negative relationship between maternal childhood trauma and child cognitive development. Analyses did not support this hypothesis. Specifically, maternal childhood trauma was not significantly associated with child cognitive development nor the four dimensions of maternal caregiving behavior. However, caregiving behavior (specifically maternal sensitivity and limit setting) was associated with child cognitive development, when controlling for maternal childhood trauma and child age. The lack of associations observed suggests that protective factors may buffer the intergenerational impact of childhood trauma. Furthermore, the relationship between quality of caregiving and child cognitive development highlights the importance of interventions which foster sensitive caregiving behaviors that may bolster child cognitive development in the context of maternal substance use disorder and maternal childhood trauma.

Analysis of self-monitoring of blood glucose metrics in gestational diabetes mellitus and their association with infants born large for gestational age: A historical observational cohort study of 879 pregnancies.

Self-monitoring of blood glucose (SMBG) is the standard of care for women with gestational diabetes mellitus (GDM). This study aimed to review SMBG profiles in women with GDM and to examine how glucose metrics derived from SMBG relate to fetal overgrowth and infants born large for gestational age (LGA, >90th percentile). This was a single-center, historical, observational cohort study of 879 GDM pregnancies in Sweden. The diagnosis of GDM was based on a universal 75 g oral glucose tolerance test at gestational week 28 or 12 in high-risk women. The glucose metrics derived from the SMBG profiles were calculated. Treatment targets for glucose were <5.3 mmol/L fasting, and ≤7.8 mmol/L 1-h postprandial. The median (interquartile range) number of glucose measurements in the analysis for each woman was 318 (216-471), including 53 (38-79) fasting glucose measurements. Associations between glucose metrics and LGA were analyzed using binary logistic regression analysis adjusted for maternal age, body mass index, smoking, nulliparity, and European/non-European origin. Receiver operating characteristic (ROC) curves were used to evaluate glucose levels for LGA prediction. Differences in means were tested using analysis of variance. The proportion of LGA infants was 14.6%. Higher mean glucose levels and smaller proportion of readings in target (glucose 3.5-7.8 mmol/L) were significantly associated with LGA (odds ratio [95% confidence interval]: 3.06 [2.05-4.57] and 0.94 [0.92-0.96], respectively). The strongest association was found with mean fasting glucose (3.84 [2.55-5.77]). The ability of mean fasting glucose and overall mean glucose to predict LGA infants in the ROC curves was fair, with areas under the curve of 0.738 and 0.697, respectively (p < 0.001). The corresponding discriminating thresholds were 5.3 and 6.1 mmol/L, respectively. Mean glucose levels increased and readings in target decreased with increasing body mass index category and at each step of adding pharmacological treatment, from diet alone to metformin and insulin (p < 0.001). Higher mean glucose levels and a smaller proportion of readings within the target range were associated with an increased risk of LGA. Suboptimal glucose control is associated with obesity and the need for pharmacological treatment.

Necrotizing enterocolitis following spontaneous intestinal perforation in very low birth weight neonates.

Necrotizing enterocolitis (NEC) and spontaneous intestinal perforation (SIP) are severe gastrointestinal complications of prematurity. The clinical presentation and treatment of NEC and SIP (peritoneal drain vs laparotomy) can overlap; however, the pathogenesis is distinct. Therefore, a patient initially treated for SIP can subsequently develop NEC. This phenomenon has only been described in case reports, and no risk factor evaluation exists. We evaluate clinical characteristics, risk factors, and outcomes of patients treated for a distinct episode of NEC after SIP. We performed a retrospective review of very low birth weight (<1500 g) neonates who presented with pneumoperitoneum between 07/2004 and 09/2022. Data was obtained from two separate neonatal intensive care units that were part of the same institution. Patients with an initial preoperative, intraoperative, or pathological diagnosis of NEC were excluded. Patients with an intraoperative diagnosis of SIP or preoperative diagnosis of SIP successfully treated with a peritoneal drain (PD) were evaluated. Patients subsequently treated (medically or surgically) for NEC after SIP were then compared to SIP-alone patients. Clinical characteristics included demographics, gestational age (GA), birth weight (BW), perinatal risk factors (chorioamnionitis, steroids, indomethacin), postoperative feeding regimen, and length of stay (LOS) were compared. Of the 278 patients included, 31 (11.2%) patients had NEC after SIP. There was no difference in GA (25 weeks vs 25 weeks, p = 0.933) or BW (760 g vs 735 g, p = 0.370) between NEC after SIP vs SIP alone cohorts, respectively. Twenty (64%) of NEC after-SIP patients were previously treated with LP. NEC after SIP occurred with a median onset of 56 days. Pneumatosis was the most frequent (81%) presenting symptom and 12 (39%) patients had hematochezia. Four (12.9%) patients required LP for NEC and all had NEC intraoperatively and on pathology. A majority (77.4%) of patients were on breast milk (BM) at time of NEC diagnosis. NEC after SIP patients had lower maternal age at delivery (29.0 vs 25.0, p = 0.055) and the incidence of NEC after LP (primary or failed drain) was higher than PD alone (16.7% vs 6.2%, p = 0.007). NEC after SIP patients had longer LOS (135 vs 81, p < 0.001). We report an 11.2% incidence of NEC at a median of 56 days following successful treatment of SIP, resulting in increased LOS. SIP patients are a high-risk cohort and protocols to prevent this phenomenon should be investigated.

Maternal dysbiosis produces long-lasting behavioral changes in offspring.

Advanced maternal age (AMA) is defined as a pregnancy in a woman older than 35 years of age. AMA increases the risk for both maternal and neonatal complications, including miscarriage and stillbirth. AMA has also been linked to neurodevelopmental and neuropsychiatric disorders in the offspring. Recent studies have found that age-associated compositional shifts in the gut microbiota contribute to altered microbial metabolism and enhanced inflammation in the host. We investigated the specific contribution of the maternal microbiome on pregnancy outcomes and offspring behavior by recolonizing young female mice with aged female microbiome prior to pregnancy. We discovered that pre-pregnancy colonization of young dams with microbiome from aged female donors significantly increased fetal loss. There were significant differences in the composition of the gut microbiome in pups born from dams recolonized with aged female biome that persisted through middle age. Offspring born from dams colonized with aged microbiome also had significant changes in levels of neurotransmitters and metabolites in the blood and the brain. Adult offspring from dams colonized with an aged microbiome displayed persistent depressive- and anxiety-like phenotypes. Collectively, these results demonstrate that age-related changes in the composition of the maternal gut microbiome contribute to chronic alterations in the behavior and physiology of offspring. This work highlights the potential of microbiome-targeted approaches, even prior to birth, may reduce the risk of neuropsychiatric disorders.

Complications among assisted reproductive technique (ART) twin gestations versus spontaneously conceived twin gestations (SC): A retrospective outcome analysis among an Afro-Caribbean population at a university-based hospital in Jamaica

Aim: The aim of the study is to compare the frequency of maternal and neonatal complications among pregnant women with twin pregnancies conceived spontaneously versus conceived by assisted reproductive technique (ART). Methods: Univariate and bivariate analyses of maternal characteristics and neonatal outcomes were performed in this retrospective cohort study at a university-based hospital between 2006 and 2016 in Jamaica, a middle-income Caribbean country. Neonatal data were the primary outcomes: APGAR scores, gestational age, birth weight, admission to the neonatal intensive care unit (NICU), and the level of ventilatory support required. Maternal characteristics, comorbidities, and pregnancy complications were other outcomes studied. Results: There were 157 SC and 27 ART twin gestations. Women conceiving via ART were more likely to be advanced maternal age (p greater 0.001), have uterine fibroids (p greater 0.001), previous myomectomy (p=0.001), and incompetent cervix (p=0.003), delivery by cesarean section (p=0.007), and experience hemorrhage (p=0.017) than SC. There were no statistically significant differences in rates of preterm births, birth weight, APGAR scores, or NICU admissions. Assisted reproductive technique twins were more likely to require continuous positive airway pressure (CPAP) (p=0.025), with no differences observed between the two groups for neonatal respiratory distress. Conclusion: In our predominantly Afro-Caribbean population, ART mothers were observed to have more poor maternal outcomes than mothers who conceived spontaneously. Assisted reproductive technique and SC twins had similar neonatal outcomes; however, ART twins were more likely to require CPAP.

Risk factors for neonatal admission from the beginning of pregnancy in Northeast Spain.

Maternal health and gestational control are crucial to improving the newborn's prognosis. This study analyses demographic and obstetric factors at the beginning of pregnancy related to neonatal health, assessing their impact on the risk of hospital admission and prematurity. Observational retrospective study conducted in Northeast Spain with data of 9560 newborns between February 2017 and February 2022. The following have been evaluated as risk factors for hospital admission: nulliparity, multiple gestation, fertilisation techniques, foreign maternal origin, maternal age, smoking and residential location, dividing the sample according to gestational age. Hypothesis testing and logistic regression were performed. Nulliparity, fertilisation techniques and multiple gestation represent a risk factor for neonatal admission (OR 22.48, 4.04 and 3.34, respectively), especially in premature newborns <32 weeks of GA (OR: 30.71, 10.71 and 22.76, respectively). Foreign maternal origin also adds risk of admission, both in term newborns (OR 1.26; CI: 1.10-1.43) and in premature babies <32 weeks of GA (OR 1.61; CI: 1.09-2.38). Tobacco does not present a significant risk of neonatal admission. The multivariate analysis model confirms the influence of the following factors in all the studied groups: nulliparity, multiple gestation and foreign maternal origin. Nulliparity and multiple pregnancies are both main risk factors for neonatal admission and premature delivery. The use of fertilisation techniques and the foreign origin of the mother significantly associate increased risk of admission and neonatal prematurity. These findings underscore the need for a comprehensive approach to prenatal care to improve neonatal prognosis and promote long-term health in risk populations.

Validity of self-reported number of pregnancies and maternal age at first birth among females attending organized mammographic screening.

Reproductive history conveys information about potential health risks later in adulthood. This study aimed to examine the validity of self-reported number of pregnancies and maternal age at first birth (AFB) among females attending BreastScreen Norway. Participants were identified through the Janus Serum Bank cohort in Norway and were eligible for this cross-sectional validation study if they participated in a health survey issued by BreastScreen Norway between 2006 and 2015. Retrospective self-reported survey information on number of pregnancies and AFB in years was validated against prospectively collected information from the Medical Birth Registry of Norway (MBRN) using the Spearman rank (rs) and intraclass correlation coefficients (ICC) with 95% confidence intervals (CI). After exclusions, 51,598 subjects were included in the analysis on number of pregnancies and 46,919 in the analysis on AFB. On average, study subjects were 59-60 years old when completing the health survey and had become first-time mothers roughly 36 years earlier. Survey-based information about number of pregnancies was highly correlated and demonstrated high agreement with the registry data (rs=0.967, 95% CI 0.964-0.969; ICC=0.884, 95% CI 0.882-0.885). Survey-based information about AFB demonstrated even higher correlation and very high agreement with the registry data (rs=0.975, 95% CI 0.973-0.976; ICC=0.974, 95% CI 0.974-0.975). Retrospectively recalled survey-based information about number of pregnancies and AFB was highly accurate when validated against prospectively collected information in the MBRN. These survey-based data are valuable for future epidemiological research, and linkage to the MBRN may not be required when these data are available.

Study of the Association Between Socioeconomic Determinants and Pregnancy Follow-Up Indicators of Mothers of Low-Birth-Weight Infants: Insights for Achieving Sustainable Development Goals

Aims: This study investigates the association between socioeconomic determinants and pregnancy follow-up among 200 mothers of low-birth-weight newborns. By identifying factors influencing maternal care and birth outcomes, the study contributes to achieving Sustainable Development Goals (SDG) 3, 8, and 10, focusing on improving maternal and child health, reducing socioeconomic disparities, and ensuring equitable healthcare access. Methods: A prospective descriptive study was conducted over 12 months (June 2020–July 2021) at the neonatology and nutrition reference center of Rabat Children's Hospital. The study recruited 206 mother-child pairs, focusing on those with low-birth-weight infants. Results: Among the 200 mothers, 92% followed their pregnancies. Distribution of prenatal consultations was as follows: 0.54% had one visit, 5.98% two visits, 33.7% three, 41.85% four, and 17.93% more than four. Analysis revealed significant associations between pregnancy follow-up and socioeconomic factors. Maternal age (p &lt; 0.001), education level (p &lt; 0.001), and place of residence significantly influenced pregnancy monitoring, with urban mothers more likely to receive follow-up care. Single mothers had a 100% non-tracking rate, while married mothers predominantly monitored their pregnancies. Conclusions: This study demonstrates the strong influence of sociodemographic factors on antenatal care use, aligning with findings from other contexts. It contributes new insights into the specific characteristics of our study population and has practical implications for shaping maternal and child health policies, addressing the unique needs of diverse sub-populations. Achieving SDG 3 (Good Health and Well-being), SDG 8 (Decent Work and Economic Growth), and SDG 10 (Reduced Inequalities) requires targeted interventions that improve equitable access to quality maternal care.

Predictors and number of antenatal care visits among reproductive age women in Sub-Saharan Africa further analysis of recent demographic and health survey from 2017-2023: Zero-inflated negative binomial regression.

Antenatal care (ANC) is an important component of maternal and child health care. To reduce perinatal mortality and improve women's experience of care, the World Health Organization (WHO) recommends pregnant women should attend at least eight ANC visits. However, in Sub-Saharan Africa (SSA), the mean number of ANC visits among reproductive-age women using Demographic and Health Surveys (DHS) data following the new WHO recommendation is so far limited. Therefore, the study aimed to determine the mean number of ANC visits and its predictors among reproductive-age women in SSA. Community-based cross-sectional study was conducted among 188,880 weighted reproductive-age women in SSA using a recent round of DHS data from 2017-2023. Zero-inflated negative binomial regression (ZINB) was conducted and statistical significance was declared at p-value <0.05 and adjusted incidence rate ratio(AIRR) for count model part and adjusted odds ratio for logit model inflated part of ZINBR with 95% confidence interval (CI) were reported. The mean number of ANC visits among reproductive-age women in SSA was 4.08 with 95%CI [4.07, 4.09]. Among reproductive-age women who gave birth in the last five years before the survey, 7.3% had eight or more ANC visits during pregnancy. Age of women, maternal and husband educational status, types of pregnancy, birth order, household size, number of under-five children, and wealth index were associated with the numbers of ANC visits among reproductive-age women in Sub-Saharan. The mean number of ANC visits among reproductive-age women in SSA is too lower than the new WHO recommendation of ANC visits for a positive pregnancy experience. This study also highlights that the proportion of at least eight ANC visits is low and there are still disparities in the mean of ANC visits across different regions of SSA. The increasing maternal age, higher maternal and husband educational status, wanted pregnancy, the number of household members, the number of under-five children, and higher wealth index increase the number of ANC visits. Unwanted pregnancy, no more fertility desire, and rural residences were contributed for zero ANC visits in SSA. Therefore, efforts should be geared towards improving maternal and husband's educational status. We strongly recommend that the governments of SSA countries should empower women economically and educationally to achieve the goals of ANC as recommended by the WHO.

The association of increased incidence of congenital heart disease in newborns with maternal COVID-19 infection during pregnancy

This paper aims to examine the potential link between maternal COVID-19 infection during pregnancy and the increased risk of congenital heart disease (CHD) in newborns. A comparative analysis was conducted involving two groups: mothers infected with COVID-19 during pregnancy and a control group. Data on maternal characteristics, pregnancy-related complications, and newborn outcomes were collected and analyzed. Additionally, the annual incidence rates of CHD from 2020 to 2023 were evaluated to assess trends over time. No significant differences were found between the COVID-19 cases and the control group in terms of maternal age, BMI, gravidity, parity, use of assisted reproductive technology, adverse obstetric history, or complications during pregnancy, including diabetes mellitus, preeclampsia, and thyroid abnormalities. For newborn outcomes, there were no significant differences in sex distribution, rate of cesarean delivery, Apgar scores, or birth weight. However, a significantly higher prevalence of cardiac ultrasound abnormalities was observed in the COVID-19 group (10.08%) compared to the control group (4.13%, p = 0.012). Further analysis revealed that the majority of cardiac abnormalities in the COVID-19 group occurred in mothers infected before 8 weeks of pregnancy. The annual incidence rates of CHD showed a significant increase during the COVID-19 pandemic, with the highest rate in 2023 (5.46%) compared to previous years. Maternal COVID-19 infection during pregnancy may adversely affect the development of the newborn’s heart. This could be due to the inflammatory response caused by the viral infection or other pathological processes. The findings underscore the importance of vigilant prenatal care and early detection of cardiac abnormalities during the pandemic and suggest the need for further research to explore potential mechanisms and intervention strategies.

Altered placental expression of genes related to Vitamin D Metabolism and their correlation with spiral artery remodeling in Preeclamptic Women

Background: Several studies reveals the correlation of preeclampsia (PE) with low vitamin D (VD) level due to disturbed trophoblast invasion and failure of spiral artery remodeling. The metabolism of VD is regularized by it signaling molecules expressed by the placenta during pregnancy. Therefore, this study was designed to assess and compare the levels of VD and it signaling molecules in placentae from normotensive and preeclamptic pregnancies and their correlation with spiral artery remodeling.Methods: This study was carried out at Department of Anatomy at Liaquat University of Medical &amp; Health Sciences, Jamshoro after ethical approval on placentae of 122 parturients; 61 from normal and 61 from preeclampsia, data was collected on predesigned proforma and was analyzed on SPSS 23.Results: The mean and standard deviation of maternal age, gestational age, and parity was 32.73±5.9 years, 37.3±3.6 weeks and 3±1 respectively. The wall thickness of SA and VD when compared in two groups found statically significant. Vitamin D signaling molecules were determined by immunostaining compared in two groups by applying Mann Whitney U test and Pearson’s correlation which reveals significant differences in preeclamptic versus controls.Conclusions: Despite extensive research indicating a link between low levels of VD and its signaling molecules in the context of inadequate spiral artery remodeling, there is still a need for further investigation to fully understand the mechanisms underlying this association in preeclampsia.Keywords: Preeclampsia; Remodeling; Spiral artery; Vitamin D; Vitamin D signaling molecules

Clinical and dental predictors of preterm birth using machine learning methods: the MOHEPI study.

Preterm birth (PTB) is one of the most common and serious complications of pregnancy, leading to mortality and severe morbidities that can impact lifelong health. PTB could be associated with various maternal medical condition and dental status including periodontitis. The purpose of this study was to identify major predictors of PTB among clinical and dental variables using machine learning methods. Prospective cohort data were obtained from 60 women who delivered singleton births via cesarean section (30 PTB, 30 full-term birth [FTB]). Dependent variables were PTB and spontaneous PTB (SPTB). 15 independent variables (10 clinical and 5 dental factors) were selected for inclusion in the machine learning analysis. Random forest (RF) variable importance was used to identify the major predictors of PTB and SPTB. Shapley additive explanation (SHAP) values were calculated to analyze the directions of the associations between the predictors and PTB/SPTB. Major predictors of PTB identified by RF variable importance included pre-pregnancy body mass index (BMI), modified gingival index (MGI), preeclampsia, decayed missing filled teeth (DMFT) index, and maternal age as in top five rankings. SHAP values revealed positive correlations between PTB/SPTB and its major predictors such as premature rupture of the membranes, pre-pregnancy BMI, maternal age, and MGI. The positive correlations between these predictors and PTB emphasize the need for integrated medical and dental care during pregnancy. Future research should focus on validating these predictors in larger populations and exploring interventions to mitigate these risk factors.

Comparative Analysis of Fluorescence In Situ Hybridization and Next-Generation Sequencing in Sperm Evaluation: Implications for Preimplantation Genetic Testing and Male Infertility.

Pre-implantation genetic testing (PGT) is a crucial process for selecting embryos created through assisted reproductive technology (ART). Couples with chromosomal rearrangements, infertility, recurrent miscarriages, advanced maternal age, known single-gene disorders, a family history of genetic conditions, previously affected pregnancies, poor embryo quality, or congenital anomalies may be candidates for PGT. Preimplantation genetic testing for aneuploidies (PGT-A) enables the selection and transfer of euploid embryos, significantly enhancing implantation rates in assisted reproduction. Fluorescence in situ hybridization (FISH) is the preferred method for analyzing biopsied cells to identify these abnormalities. While FISH is a well-established method for identifying sperm aneuploidy, NGS offers a more comprehensive assessment of genetic material, potentially enhancing our understanding of male infertility. Chromosomal abnormalities, arising during meiosis, can lead to aneuploid sperm, which may hinder embryo implantation and increase miscarriage rates. This review provides a comparative analysis of fluorescence in situ hybridization (FISH) and next-generation sequencing (NGS) in sperm evaluations, focusing on their implications for preimplantation genetic testing. This analysis explores the strengths and limitations of FISH and NGS, aiming to elucidate their roles in improving ART outcomes and reducing the risk of genetic disorders in offspring. Ultimately, the findings will inform best practices in sperm evaluations and preimplantation genetic testing strategies.
