Parental expectations of raising a child with disability in decision-making for prenatal testing and termination of pregnancy: A mixed methods study

The performance evaluation of NIPT for fetal chromosome microdeletion/microduplication detection: a retrospective analysis of 68,588 Chinese cases

Background

Chromosomal abnormalities are the main cause of birth defects in newborns. Since the inception of noninvasive prenatal testing (NIPT) technology, it has primarily been applied to the detection of common trisomy (T21, T18, T13). However, the application of NIPT in microdeletion and microduplication detection is still controversial.

Methods

This study retrospectively analyzed the data of 68,588 cases that underwent NIPT at Ganzhou Maternal and Child Health Hospital in China. These data were used to evaluate the performance of NIPT in fetal chromosome microdeletion/microduplication detection and to investigate the key factors affecting the NIPT performance.

Results

A total of 281 cases (0.41%) had positive NIPT results with copy number variants (CNVs), of which 161 were validated by karyotyping and chromosome microarray analysis (CMA). Among the 161 cases, 92 were confirmed as true positives through karyotyping or CMA, including 61 microdeletion cases and 31 microduplication cases, resulting in a positive predictive value (PPV) of 57.14%. Improvements in library construction methods increased the fraction of cell-free fetal DNA (cffDNA) from 13.76% to 18.44%, leading to a significant improvement in the detection rate (0.47% vs. 0.15%) and PPV (59.86% vs. 28.57%) of NIPT for CNVs.

Conclusion

This study proved the robust performance of NIPT for fetal chromosome microdeletion/microduplication detection. In addition, the cffDNA fraction is a key factor influencing NIPT, with increased cffDNA fraction improving the performance of NIPT.

Patient Experience and Decision-Making Process for Laser Photocoagulation for Monochorionic Twin Pregnancy: A Qualitative Exploration

INTRODUCTION

The aim of the study was to explore patients' perspectives on diagnosis and treatment options for complicated monochorionic multiple gestations, and experiences with fetoscopic laser photocoagulation.

METHODS

This is a prospective cohort study of patients undergoing laser photocoagulation. Participants were interviewed during pregnancy and the postpartum period. Qualitative analysis was performed.

RESULT

Twenty-seven patients who were candidates for laser photocoagulation were included. All elected to have laser photocoagulation. Patients chose surgery with goals of improving survival, decreasing the risk of preterm delivery, and improving the long-term health of their fetuses. They demonstrated accurate knowledge of the risks and benefits of treatment. Most (74%) felt that laser photocoagulation represented their only viable clinical option. Few seriously considered pregnancy termination or selective reduction (7% and 11% respectively). Postpartum, patients expressed no regrets about their decisions for surgery, but many felt unprepared for the challenges of preterm delivery.

CONCLUSION

Participants weighed treatment options similarly to fetal specialists. They acknowledged but did not seriously consider treatments other than fetoscopic laser photocoagulation and were highly motivated to do whatever they could to improve outcomes for their fetuses.

Maternal healthcare for women with physical disabilities in Northern Vietnam: perspectives of healthcare providers

BACKGROUND

Pregnancy among women with physical disabilities is common around the world; however, there are limited qualitative studies that explore the perspectives of healthcare providers toward pregnant women with disabilities outside of the Global North.

OBJECTIVE

This article explores perspectives and experiences of maternal healthcare providers in the delivery of services to women with physical disabilities in Northern Vietnam.

METHODS

Semi-structured interviews were conducted with 14 healthcare providers who worked in public and/or private healthcare North Vietnamese facilities where maternal services were provided. Data were thematically analyzed.

RESULTS

The participants included six males and eight females. Ten were obstetricians/gynecologists, one was a doctor specializing in obstetric imaging diagnosis, three were midwives, and one was a midwife/assistant doctor. Four themes were identified. In the first theme, providers attached provisos to the right to motherhood including the view that the women were limited to one child and should undergo prenatal screenings for fetal abnormalities. In the second theme, the providers reported that disability was not incorporated into their education; this led to half of them lacking confidence in providing appropriate maternal healthcare services for women with physical disabilities. The third theme found that although women with physical disabilities were considered as a priority group, decisions around who was seen before others or provided with fee discount/exemption were left in the hands of staff. The fourth theme identified that some providers overlooked their needs for physical accessibility and independence.

CONCLUSION

This study shows that maternal healthcare providers in Vietnam discounted the needs of women with physical disabilities. The needs of women with disabilities should be included in the training of maternal healthcare providers in Vietnam.

The experiences of mothers of children with hydrocephalus in Jordan: A phenomenological study

BACKGROUND

Available literature showed that mothers of children with hydrocephalus experience many challenges. Studies that described mothers' experiences in caring for their children with hydrocephalus are limited. Understanding the mothers' experiences and challenges is essential and may enable the provision of increased knowledge and support for these mothers.

AIM

The aim of this study was to explore the lived experiences of Jordanian mothers of children with hydrocephalus.

METHODOLOGY

A phenomenological descriptive approach was applied in this study, using semi-structured interviews with a purposive sample of 10 mothers of children with hydrocephalus. Transcribed interviews were analyzed using thematic approach.

RESULT

Three main themes that explored the mothers' experiences emerged from the data analysis process. The first theme was the impact of living with a child with hydrocephalus. Four subthemes comprise this theme; namely the mothers' initial response, overwhelming responsibilities, social withdrawal, and adapting: loving the baby and growing stronger. The second theme was related to the support system. Two subthemes compose this theme; the role of husband, and social support. The last theme was related to feelings of uncertainty. Two subthemes constitute this theme; concerns about the child's future and considering abortion as a solution.

CONCLUSION

The mothers in this study were found to have experienced many intense feelings and to have faced many stressors and difficulties associated with the different stages of their child's illness. This study provides evidence that could be used to develop guidelines to support mothers of children with hydrocephalus.

Assessing the Content Quality of Online Parental Resources about Newborn Metabolic Disease Screening: A Content Analysis

Parents increasingly utilise the internet to obtain information on health practices, but the quality of online information about screening for inherited metabolic diseases (IMD) needs to be improved. A content analysis examined how IMD blood and urine tests were described online in local healthcare sectors between May and June 2021. Among the nine resources, four were blood test providers and five were urine test providers. All mentioned the test benefits and procedures. Other information, such as false-positive/negative or risk of pain, was infrequently mentioned. The descriptions of urine tests are advertised as outperforming blood tests and can be purchased from commercial laboratory sites without medical guidance. Two urine test providers claimed no false results were reported. A few commercial advertisements highlighted the simplicity of the urine test and potentially overstated the invasiveness of the blood test. We found that some advertisements described IMD as "silent killers" and emphasised the advantage of getting "reassurance" in controlling the child's developmental health and well-being. To better protect the parents, or broadly, the public interest, regulatory and oversight measures on the urine tests should be implemented to promote the proper use of genetic tests. Without timely regulation and oversight, the incorrect descriptions might create a public misconception about utilising these commercial laboratory tests to inform health decisions.

The Emergence and Global Spread of Noninvasive Prenatal Testing

Since its introduction in 2011, noninvasive prenatal testing (NIPT) has spread rapidly around the world. It carries numerous benefits but also raises challenges, often related to sociocultural, legal, and economic contexts. This article describes the implementation of NIPT in nine countries, each with its own unique characteristics: Australia, Canada, China and Hong Kong, India, Israel, Lebanon, the Netherlands, the United Kingdom, and the United States. Themes covered for each country include the structure of the healthcare system, how NIPT is offered, counseling needs and resources, and cultural and legal context regarding disability and pregnancytermination. Some common issues emerge, including cost as a barrier to equitable access, the complexity of decision-making about public funding, and a shortage of appropriate resources that promote informed choice. Conversely, sociocultural values that underlie the use of NIPT vary greatly among countries. The issues described will become even more challenging as NIPT evolves from a second-tier to a first-tier screening test with expanded use.

Decision-making factors in prenatal testing: A systematic review

This review examines the factors that affect the decision-making process of parental couples evaluating prenatal screening and diagnostic tests. A systematic search was performed using PubMed and PsycInfo databases. The 46 included studies had to: investigate the decision-making process about prenatal testing; focus on tests detecting trisomy 21, 18, 13, and abnormalities of sex chromosomes; be published in English peer-reviewed journals. The decision-making process seems composed of different levels: an individual level with demographic, clinical, and psychological aspects; a contextual level related to the technical features of the test and the information received; a relational level involving family and society.
