Review
Since its debut in 2011, Non-Invasive Prenatal Testing (NIPT) has continually demonstrated its effectiveness in detecting an expanding number of diseases. NIPT offers a less invasive approach to prenatal chromosomal disease screening, providing prospective parents with vital information to better prepare for their potential pregnancy outcomes. NIPT was primarily designed for screening trisomy 13, 18, and 21. However, its scope has since broadened to encompass microdeletions and autosomal dominant monogenic diseases. Conversely, the normalization of NIPT can have unintended consequences. Some patients opt for NIPT without any medical indications, driven by a desire to remain cautious. This over-screening for chromosomal abnormalities can exacerbate pregnancy-related anxiety, as individuals might feel pressured into taking the test unnecessarily. While NIPT can be highly successful when conducted correctly, it is not infallible, and obstetricians play a crucial role in managing patient expectations. This includes providing genetic counseling to individuals with relevant genetic information regarding their personal and family histories. In the context of NIPT, a bioinformatics analysis is performed on a cell-free DNA (cfDNA) sample extracted from the mother's placenta to determine the fetal fraction (FF). This FF measurement is vital for quality control and ensuring statistical confidence in the test results. Raising awareness among clinicians about the significance of FF enhances patient care and alleviate concerns about the possibility of failed NIPT. This paper aims to explore the ongoing debates and more specifically the significance and pitfalls of NIPT on a psychosocial and ethical scale, all while highlighting the importance of genetic counseling.

BACKGROUND
Substance use and cardiovascular (CV) events are increasing among pregnant women in the United States, but association between substance use in pregnancy and CV events remains unknown.
OBJECTIVES
The purpose of this study was to examine the association between substance use and acute CV events in pregnancy.
METHODS
We identified all women with a delivery hospitalization between 2004 and 2018 in the Nationwide Inpatient Sample, stratified on the presence or absence of substance use. The primary outcome was any acute CV event, defined as the presence of: acute myocardial infarction, stroke, arrhythmia, endocarditis, acute cardiomyopathy or heart failure, or cardiac arrest. Secondary outcomes were individual acute CV events, major adverse cardiac events, and maternal mortality. The association between substance use and outcomes were examined using multivariable logistical regression.
RESULTS
A total of 60,014,368 delivery hospitalizations occurred from 2004 to 2018, with substance use complicating 955,531 (1.6%) deliveries. Substance use was independently associated with CV events (adjusted odds ratio [aOR]: 1.61; 95% CI: 1.53-1.70; < 0.001), major adverse cardiac events (aOR: 1.53; 95% CI: 1.46-1.61; < 0.001), and maternal mortality (aOR: 2.65; 95% CI: 2.15-3.25; < 0.001) during delivery hospitalization. All individual substances had an increased association with CV events; however, amphetamine/methamphetamine had the strongest association (aOR: 2.71; 95% CI: 2.35-3.12; < 0.001). All substances other than cocaine and cannabis had a significant association with maternal death.
CONCLUSIONS
Substance use has a strong association with acute CV events and maternal mortality during hospitalization for delivery and women with substance use warrant increased surveillance for CV events during this time.

BACKGROUND
Patients with congenital heart disease (CHD) have a higher incidence of arrhythmias during pregnancy, yet the utility of mobile cardiac telemetry (MCT) to predict adverse outcomes is unknown.
OBJECTIVES
The purpose of this study is to determine whether arrhythmias on screening MCT correlate with adverse pregnancy outcomes.
METHODS
Patients with CHD prospectively enrolled in the Standardized Outcomes in Reproductive Cardiovascular Care initiative underwent 24-hour MCT (within 18 months prior to pregnancy). Positive findings on MCT were defined as episodes of bradyarrhythmia, symptomatic atrioventricular block, ectopic atrial or ventricular activity, and supraventricular or ventricular tachycardia. Clinically significant arrhythmia events (CSAEs) were those requiring medical or device intervention or an emergency room visit. Clinical events during the antepartum, intrapartum, and postpartum periods were compared using Fisher's exact test. Analyses were performed using Stata version 16.
RESULTS
In 141 pregnancies in 118 patients with CHD, MCT detected positive findings in 17%. Adverse cardiac outcomes occurred in 11% of pregnancies, of which CSAE occurred in 3.5%. Positive MCT was significantly associated with subsequent CSAE (21% vs 0%, < 0.001) and cumulative adverse maternal cardiac outcomes (33% vs 7%, = 0.001) but did not correlate with obstetric (46% vs 41%, = 0.660) or neonatal outcomes (33% vs 31%, = 0.810). Of the patients with CSAE, 75% had ≥moderate CHD complexity.
CONCLUSIONS
Patients with CHD had a high rate of positive MCT findings. This was associated with CSAE and adverse maternal cardiac outcomes. Patients with ≥moderate CHD complexity may benefit from screening MCT to improve preconceptual counseling and planning.

BACKGROUND
Health economic assessments are used to determine whether the resources needed to generate net benefit from an antenatal or newborn screening programme, driven by multiple benefits and harms, are justifiable. It is not known what benefits and harms have been adopted by economic evaluations assessing these programmes and whether they omit benefits and harms considered important to relevant stakeholders.
OBJECTIVES
(1) To identify the benefits and harms adopted by health economic assessments in this area, and to assess how they have been measured and valued; (2) to identify attributes or relevance to stakeholders that ought to be considered in future economic assessments; and (3) to make recommendations about the benefits and harms that should be considered by these studies.
DESIGN
Mixed methods combining systematic review and qualitative work.
SYSTEMATIC REVIEW METHODS
We searched the published and grey literature from January 2000 to January 2021 using all major electronic databases. Economic evaluations of an antenatal or newborn screening programme in one or more Organisation for Economic Co-operation and Development countries were considered eligible. Reporting quality was assessed using the Consolidated Health Economic Evaluation Reporting Standards checklist. We identified benefits and harms using an integrative descriptive analysis and constructed a thematic framework.
QUALITATIVE METHODS
We conducted a meta-ethnography of the existing literature on newborn screening experiences, a secondary analysis of existing individual interviews related to antenatal or newborn screening or living with screened-for conditions, and a thematic analysis of primary data collected with stakeholders about their experiences with screening.
RESULTS
The literature searches identified 52,244 articles and reports, and 336 unique studies were included. Thematic framework resulted in seven themes: (1) diagnosis of screened for condition, (2) life-years and health status adjustments, (3) treatment, (4) long-term costs, (5) overdiagnosis, (6) pregnancy loss and (7) spillover effects on family members. Diagnosis of screened-for condition (115, 47.5%), life-years and health status adjustments (90, 37.2%) and treatment (88, 36.4%) accounted for most of the benefits and harms evaluating antenatal screening. The same themes accounted for most of the benefits and harms included in studies assessing newborn screening. Long-term costs, overdiagnosis and spillover effects tended to be ignored. The wide-reaching family implications of screening were considered important to stakeholders. We observed good overlap between the thematic framework and the qualitative evidence.
LIMITATIONS
Dual data extraction within the systematic literature review was not feasible due to the large number of studies included. It was difficult to recruit healthcare professionals in the stakeholder's interviews.
CONCLUSIONS
There is no consistency in the selection of benefits and harms used in health economic assessments in this area, suggesting that additional methods guidance is needed. Our proposed thematic framework can be used to guide the development of future health economic assessments evaluating antenatal and newborn screening programmes.

OBJECTIVES
Chronic anaemia is a significant health concern, particularly among women of childbearing age. Factors such as menstrual blood loss, childbirth, inadequate nutrition, closely spaced pregnancies, and recurrent gastrointestinal bleeding increase the risk of anaemia. This study investigated whether current contraceptive methods are associated with anaemia in Indian women of reproductive age.
METHODS
Cross-sectional data from the fifth round of the National Family Health Survey, conducted in 2019-21, were used for this investigation (NFHS-5). We included only non-pregnant and non-amenorrhoeic women in our analysis, resulting in a final analytical sample of 673,094 women aged 15-49. Bivariate cross-tabulations and multivariable logistic regression were employed to analyse the data.
RESULTS
The prevalence of anaemia was 57%, and the adjusted regression models found no significant association between the use of any contraceptive methods and women's haemoglobin status. Women using traditional contraceptive methods had 1.08 (95% confidence interval, 1.048-1.113) times higher odds of having anaemia. Among the modern methods, other than injectables, all other methods-such as an intrauterine device (IUD), barrier use, and sterilisation-were associated with higher odds of anaemia compared to women who used contraceptive pills.
CONCLUSIONS
This study explored the relationship between modern contraceptives and haemoglobin levels in India, revealing that injectables were associated with a notable reduction in the odds of anaemia, whereas traditional contraceptives and other modern methods exhibited positive associations with anaemia. These findings prompt policymakers to focus on anaemia reduction and safe contraceptives. More research is needed to inform decisions, given the scant literature.

OBJECTIVES
A substantial proportion of women experience mental health challenges during pregnancy or the postpartum period. Common mental disorders (CMDs), including depression, anxiety, and obsessive-compulsive disorder, are prevalent. Identifying causes and associated risk factors is imperative for early intervention and the prevention of mental health issues.
METHODS
This study utilized data from the 2018 Basic Health Research, which was conducted nationwide in Indonesia, using a cross-sectional approach. We focused on women aged 13-49 years who were currently or previously married, and had experienced pregnancy, including 8,889 pregnant women and 77,012 women who had delivered between January 1, 2013, and August 31, 2018. The Self-Reporting Questionnaire-20 was employed to assess CMDs. Multivariate logistic regression was performed.
RESULTS
The prevalence of CMDs in pregnant women was 12.6%, while postpartum mothers exhibited a prevalence of 10.1%. Poor health status displayed the strongest impact on CMDs during both pregnancy (Adjusted Odds Ratio [AOR]: 12.23, 95% Confidence Interval [CI]: 9.06-16.60) and the postpartum period (AOR: 16.72, 95% CI: 14.85-18.82). Additional significant factors for both group include young maternal age, lack of education, unemployment, hystory of hypertension, and smoking status. Among pregnant women, CMDs was also associated with first-trimester pregnancy, previous pregnancy complications, and small upper arm circumference. For postpartum mothers, significant factors include history of abortion, unwanted pregnancy, pregnancy complications, lack of antenatal care, spontaneous delivery, postpartum complications and contraceptive use.
CONCLUSIONS
CMDs can impact in pregnant and postpartum women. Early diagnosis and management must be seamlessly integrated into primary healthcare practices.

BACKGROUND
Unintended pregnancies pose significant health risks, particularly in sub-Saharan Africa, where millions of cases are recorded annually, disproportionately affecting adolescent women. Utilization of modern contraceptives is crucial in managing fertility and reducing unintended pregnancies, abortions, and associated health complications. This study aimed to assess the prevalence, distribution and factors associated with modern contraceptives utilization among women aged 15-49 in Uganda.
METHODS
The study used secondary data from the 2016 Uganda Demographic and Health Survey (UDHS). The study sample comprise of 9,235 women aged 15-49 who used any method to prevent pregnancy in the five years preceding 2016 UDHS survey. The outcome variable for this study is utilization of modern contraceptives. Univariate, bivariate, and multilevel binary logistic regression was used to examine the relationship between individual and contextual factors on the modern contraceptive use among women aged 15-49 in Uganda. Choropleth mapping and network analysis in ArcGIS 10.8.2 was used to visualize spatial distribution of modern contraceptive use and measure community access to health facilities respectively.
RESULTS
The prevalence of modern contraceptive use was 53.19% (n = 4,919) in Uganda, with significant spatial variation by district. Higher prevalence (23.18%) was observed among women aged 20-29 compared to adolescents (4.1%). Only 21.9% of married women reported using modern contraceptives. At the individual-level, the factors that positively influenced use of modern contraceptives included: women's marital status, wealth index and level of education while sex of the household head, ever terminated a pregnancy and religion negatively affected the use of modern contraceptives. At community-level, community access to health facilities was found to have negative influence on the use of modern contraceptives among women. In communities where women frequently visited health facilities in the 12 months preceding the survey, the use of modern contraceptives reduced by 3.9%. Accessibility analysis revealed challenges, with women in northeastern districts (rural districts) facing travel times exceeding four hours to reach health facilities.
CONCLUSION
Utilization of modern contraceptives are essential for promoting women's health and well-being, particularly concerning maternal healthcare. This study highlights disparities in modern contraceptive use across age groups and the districts, emphasizing the need for targeted interventions. Policymakers and stakeholders must prioritize strategies that promote utilization of modern contraceptives and maternal healthcare services to address these disparities effectively. Such efforts are crucial for improving reproductive health outcomes and reducing the burden of unintended pregnancies and related complications in Uganda.

BACKGROUND
The nutritional status of the mothers before pregnancy and the weights gained during pregnancy are very crucial factors affecting the pregnancy outcomes and health of the infants. This study aimed to assess early pregnancy weight, determine the magnitude of gestational weight gain, and investigate the factors affecting gestational weight gain among pregnant women in the Gurage zone, 2022.
METHODS
A prospective cohort study was conducted among pregnant women who started antenatal care follow-up before the 16th week of gestation in the selected hospitals and health centers of the Gurage zone, Ethiopia. The gestational weight gain was obtained by subtracting the early pregnancy weight from the last pregnancy weight and categorizing based on the Institute of Medicine (IOM) recommendation.
RESULTS
The early pregnancy weight status of the women at enrollment indicates that 10% of them were underweight and 83% of them had normal weight. On average, the study participants gained 13.3 kgs of weight with [95% CI: 13.0, 13.6]. More than half (56%) of them gained adequate weight, a quarter (26%) of them gained inadequate weight, and 18% of them gained excess weight during pregnancy compared to the IOM recommendation. Maternal age, occupational status, and early pregnancy weight status were found to have a statistically significant association with the gestational weight gained.
CONCLUSION
Almost half (44%) of the pregnant women gained either inadequate or excess weight during pregnancy. Promoting gestational weight gain within recommended guidelines should be emphasized for younger, employed women and those who are either underweight or overweight.
