The impact of invasive prenatal testing on anxiety and sleep quality in pregnant women with a screen-positive result for aneuploidy

The emotional journey of adapting to prenatally identified trisomy X

There is a paucity of research on the experiences of parents of children with trisomy X (47,XXX). Increased prenatal diagnoses associated with advances in noninvasive prenatal screening necessitate a better understanding of how trisomy X impacts family systems. This qualitative investigation aimed to describe the lived experience of parents of young daughters with prenatally identified trisomy X to guide genetic counseling. Semi-structured qualitative interviews were conducted via teleconferencing with parents (n = 11) of girls with trisomy X, ages 6-44 months. A descriptive phenomenological approach was used to code transcripts for significant statements and reduce data into themes describing the experience of receiving a diagnosis of trisomy X and the experience of early parenting in this population. Participants described an emotional journey of adapting to prenatally identified trisomy X. Four descriptive themes included two related, yet distinct, life stages: Negative Diagnostic Experience and a Hopeful Early Childhood, as well as two ongoing experiences: Persistent Ambiguity and Coping with and Adapting to Uncertainty. Results suggest providers should carefully consider word choice and timing in delivery of diagnosis, and genetic counseling should provide expectant parents with current research specific to trisomy X, facilitate connections with other parents of young girls with trisomy X, introduce developmental monitoring approaches, and be prepared to support families with a range of emotional responses to the diagnosis and decisions regarding disclosure.

Modification of the association between nausea and vomiting of pregnancy and anxiety by personality trait during early pregnancy: A longitudinal study of Japanese pregnant women

AIM

This study aimed to elucidate whether personality traits modify the relationship between nausea and vomiting of pregnancy (NVP) and anxiety, stratified by three pregnancy periods: 5-8 weeks, 9-12 weeks, and 13-20 weeks.

METHODS

This longitudinal study was conducted from August 2018 to February 2019 at a perinatal outpatient unit in a general hospital. We included 153 pregnant women aged ≥20 years and under 20 weeks of gestation at their first prenatal visit. They completed the Index of Nausea, Vomiting, and Retching, and the State-Trait Anxiety Inventory (STAI) to measure anxiety in terms of both trait (STAI-T) and state anxiety (STAI-S), and retook them at follow-up checkups for a maximum of three times.

RESULTS

Using longitudinal data until 20 weeks' gestation, changes in NVP and trait anxiety were significantly associated with changes in state anxiety independently, with trait anxiety being more strongly involved than the change in NVP. This tendency was pronounced in the high-trait anxiety group with STAI-T scores of ≥45. Cross-sectional analyses by gestational week showed similar results in the low-trait anxiety group (STAI-T < 45). In the high-trait anxiety group, only trait anxiety was significantly associated with state anxiety up to 12 weeks gestation. However, only NVP was significantly associated with state anxiety after 13 weeks.

CONCLUSIONS

Pregnant women who tend to be anxious temperamentally may have other factors that cause anxiety besides nausea immediately after the discovery of pregnancy. Understanding personality traits may help reduce anxiety in pregnant women.

Effect of short-term psychological intervention on anxiety of pregnant women with positive screening results for chromosomal disorders: a randomized controlled trial

BACKGROUND AND AIM

Prenatal diagnosis of fetal abnormalities is a critical and stressful event for women. Most pregnant women are concerned about fetal abnormalities and screening tests. Due to the importance of anxiety reduction in pregnant women, this study was conducted to determine the effect of short-term psychological intervention on the anxiety of pregnant women with positive screening results for chromosomal disorders.

METHODS

A randomized clinical trial was performed on women referred to Akbarabadi Hospital in Tehran, Iran, who had positive screening results for chromosomal abnormalities. Participants were selected from eligible individuals by a continuous method and were assigned to two groups of cognitive-behavioral training (n = 46) and control (n = 46), using the block balanced randomization method. Participants in the cognitive-behavioral training group received 4 sessions of individual counseling. The control group received routine pregnancy visits. The Spielberger State-Trait Anxiety Inventory was completed before the intervention and immediately at the end of the intervention (before receiving the amniocentesis result). The analysis of intervention effects was performed as intention-to-treat and per-protocol analysis.

RESULTS

There was a statistically significant difference in post-intervention state anxiety scores and trait anxiety scores (p <  0.001) between the intervention and control groups, when their means were adjusted for pre-intervention scores for both intention-to-treat and per-protocol analysis. Also, there was a large effect size between the groups in terms of state (ITT: ηp2 = 0.63, PP: ηp2 = 0.71) and trait (ITT: ηp2 = 0.72, PP: ηp2 = 0.75) anxiety scores clinically for both intention-to-treat and per-protocol analysis. The intervention group had a statistically significant and large decrease in state and trait anxiety scores from pretrial to post-trial. In contrast, the control group had a statistically significant and medium increase in state and trait anxiety scores from pretrial to post-trial.

CONCLUSION

The results showed that cognitive-behavioral training reduced the anxiety of pregnant women with positive screening results for chromosomal disorders. According to the results, it is recommended to hold cognitive-behavioral training classes to reduce the anxiety of pregnant women with a positive screening result for chromosomal disorders.

Optimizing Fetal Aneuploidy Screening in an Austere Military Clinical Environment: A Prenatal Cost Comparison

INTRODUCTION

Austere clinical settings, including remote military installations, face unique challenges in screening pregnant women for aneuploidy. The objective of this study was to compare the direct and indirect prenatal costs of traditional 2-part serum-based screening to cell-free DNA (cfDNA) for detection of trisomies 18 and 21 for a military treatment facility with limited in-house perinatal resources.

MATERIALS AND METHODS

We identified Naval Hospital Guantanamo Bay as a surrogate for an austere clinical environment. A prenatal cost of care analysis incorporating direct and indirect expenses was performed to compare the 2 aneuploidy screening strategies for a theoretical cohort of 100 patients for detection of trisomies 18 and 21. The baseline aneuploidy uptake rate was determined using a historical cohort. Test performance characteristics were obtained from the contracting laboratory. Aneuploidy rates and costs were calculated using previously published data.

RESULTS

Assuming a baseline screen uptake rate of 87%, initial screening using the traditional approach would directly cost $8,285.01 versus $44,140.32 with cfDNA. Considering indirect costs such as travel, consultative services, evaluation and follow-up testing of an abnormal screen result, and lost productivity, the cost difference narrows to $14,458.25 over a 5- to 6-year period. Cost equivalence is achieved when cfDNA is priced at $341.17 per test.

CONCLUSION

Cell-free DNA as an initial screening strategy offers enhanced detection rates for trisomies 18 and 21 but remains more costly than traditional screening when incorporating direct and indirect expenses. In a low volume setting with limited resources, the added cost may be justified given the implications of unrecognized aneuploidy.
