Consistency in the Assessment of Dried Blood Spot Specimen Size and Quality in U.K. Newborn Screening Laboratories. Int J Neonatal Screen 2024; 10:60. [PMID: 39311362 PMCID: PMC11417764 DOI: 10.3390/ijns10030060] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/23/2024] [Revised: 08/30/2024] [Accepted: 08/30/2024] [Indexed: 09/26/2024] Open
Abstract
In 2015, U.K. newborn screening (NBS) laboratory guidelines were introduced to standardize dried blood spot (DBS) specimen quality acceptance and specify a minimum acceptable DBS diameter of ≥7 mm. The UK 'acceptable' avoidable repeat rate (AVRR) is ≤2%. To assess inter-laboratory variability in specimen acceptance/rejection, two sets of colored scanned images (n = 40/set) of both good and poor-quality DBS specimens were distributed to all 16 U.K. NBS laboratories for evaluation as part of an external quality assurance (EQA) assessment. The mean (range) number of specimens rejected in the first EQA distribution was 7 (1-16) and in the second EQA distribution was 7 (0-16), demonstrating that adherence to the 2015 guidelines was highly variable. A new minimum standard for DBS size of ≥8 mm (to enable a minimum of six sub-punches from two DBS) was discussed. NBS laboratories undertook a prospective audit and demonstrated that using ≥8 mm as the minimum acceptable DBS diameter would increase the AVRR from 2.1% (range 0.55% to 5.5%) to 7.8% (range 0.55% to 22.7%). A significant inverse association between the number of specimens rejected in the DBS EQA distributions and the predicted AVVR (using ≥8 mm minimum standard) was observed (r = -0.734, p = 0.003). Before implementing more stringent standards, the impact of a standard operating procedure (SOP) designed to enable a standardized approach of visual assessment and using the existing ≥7 mm diameter (to enable a minimum of four sub-punches from two DBS) as the minimum standard was assessed in a retrospective audit. Implementation of the SOP and using the ≥7 mm DBS diameter would increase the AVRR from 2.3% (range 0.63% to 5.3%) to 6.5% (range 4.3% to 20.9%). The results demonstrate that there is inconsistency in applying the acceptance/rejection criteria, and that a low AVVR is not an indication of good-quality specimens being received into laboratories. Further work is underway to introduce and maintain standards without increasing the AVRR to unacceptable levels.

Abstract
Acid sphingomyelinase deficiency (ASMD) is a rare lysosomal storage disorder (LSD) caused by reduced activity of the acid sphingomyelinase (ASM) enzyme, which leads to progressive storage of sphingomyelin and related lipids in the body. ASMD is caused by biallelic variants in the SMPD1 gene, which encodes for the ASM enzyme. Current estimates of disease incidence range from 0.4 to 0.6 in 100 000 livebirths, although this is likely an underestimation of the true frequency of the disorder. While there is no cure for ASMD, comprehensive care guidelines and enzyme replacement therapy are available, making an early diagnosis crucial. Newborn screening (NBS) for ASMD is possible through measurement of ASM activity in dried blood spots and offers the opportunity for early diagnosis. In 2015, Illinois (IL) became the first to initiate statewide implementation of NBS for ASMD. This study describes the outcomes of screen-positive patients referred to Ann & Robert H. Lurie Children's Hospital (Lurie). Ten infants were referred for diagnostic evaluation at Lurie, and all 10 infants were classified as confirmed ASMD or at risk for ASMD through a combination of molecular and biochemical testing. Disease incidence was calculated using data from this statewide implementation program and was ~0.79 in 100 000 livebirths. This study demonstrates successful implementation of NBS for ASMD in IL, with high screen specificity and a notable absence of false positive screens.

Abstract
Psychosocial consequences of false-positive results following newborn bloodspot screening have been identified as a potential risk to this highly successful public health initiative. A scoping review was undertaken in October 2023 underpinned by the Arksey and O'Malley framework. Twenty-four papers were included in the review, many of which focused on cystic fibrosis. The results indicated that impact of false-positive results is variable; some studies suggest false-positive results have the potential to result in negative sequelae including increased stress and changes in parental perceptions of their child, while others suggest these impacts are transient and, in some instances, may even lead to positive outcomes. Further evidence is needed to ensure the representation of other conditions included in newborn bloodspot screening and to support strategies to overcome potential negative sequela.

Comprehensive metabolomics analysis reveals novel biomarkers and pathways in falsely suspected glutaric aciduria Type-1 newborns. Clin Chim Acta 2024; 557:117861. [PMID: 38490341 DOI: 10.1016/j.cca.2024.117861] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Revised: 02/04/2024] [Accepted: 03/05/2024] [Indexed: 03/17/2024]
Abstract
BACKGROUND Glutaric aciduria type-1 (GA-1) is a rare metabolic disorder due to glutaryl coenzyme A dehydrogenase deficiency, causing elevated levels of glutaryl-CoA and its derivatives. GA-1 exhibits symptoms like macrocephaly, developmental delays, and movement disorders. Timely diagnosis through genetic testing and newborn screening is crucial. However, in some cases, transiently elevated level of glutarylcarnitine (C5DC) challenges accurate diagnosis, highlighting the need for alternative diagnostic methods, like mass spectrometry-based untargeted metabolomics, to identify additional biomarkers for distinguishing falsely suspected GA-1 from healthy newborns. METHODOLOGY DBS samples from falsely suspected GA-1 newborns (n = 47) and matched control were collected through the NBS program. Untargeted metabolomics using liquid chromatography-high-resolution mass spectrometry (LC-HRMS) was performed to enable biomarker and pathway investigations for significantly altered metabolites. RESULTS 582 and 546 were up- and down-regulated metabolites in transient GA-1. 155 endogenous metabolites displayed significant variations compared to the control group. Furthermore, our data identified novel altered metabolic biomarkers, such as N-palmitoylcysteine, heptacarboxyporphyrin, 3-hydroxylinoleoylcarnitine, and monoacylglyceride (MG) (0:0/20:1/0:0), along with perturbed metabolic pathways like sphingolipid and thiamine metabolism associated with the transient elevated C5DC levels in DBS samples. CONCLUSIONS A distinct metabolic pattern linked to the transient C5DC elevation in newborns was reported to enhance the prediction of the falsely positive cases, which could help avoiding unnecessary medical treatments and minimizing the financial burdens in the health sector.

Abstract
Genetic testing is increasingly used in clinical practice in the neonatal period, including in NICUs. This testing may have psychological consequences for parents. To best support families, neonatal clinicians should be aware of the various ways in which parents view and respond to genetic testing. In this review, we summarize research on the parental experience of having a newborn infant undergo genetic testing.

Abstract
We look to the past as prologue for guidance in predicting and circumventing potential psychosocial-ethical challenges, including those that may influence the attachment process for some parents. We consider the evolution of bioethics and developmental psychology as they intersect with newborn screening while exploring potential implications of positive findings, be they false positives, true positives, or secondary as well as incidental findings. We reflect on navigating the complex landscape that may be significantly impacted by variable phenotypes, the age of onset, and uncertain prognoses, mindful of the diagnostic odyssey continuum. We explore select facets of ethical and psychological challenges encountered with positive newborn screening findings by highlighting enduring debates to improve the policy process in public health and medicine. We believe substantive empirical research is needed, including long-term follow-up, routine prenatal assessment of tolerance for uncertainties, and especially innovative methodologies to better evaluate potential psychological distress that may be present in some at-risk individuals during the perinatal period preceding and following reports of positive findings. Mitigation strategies building on lessons learned from NBS and clinical follow-up should be implemented and studied. We conclude by pondering why we remain far afield from providing these services. Research directed towards understanding the implications of positive NBS findings will further reduce the burdens on families and care providers alike and should lead to improved communication.

Abstract
Newborn screening (NBS) for inherited and congenital disorders is a form of secondary disease prevention and a public health responsibility. The development of NBS programs is one of the most important achievements in health care. While the scope of the screening targets has expanded and methods have evolved, the screening process has remained essentially unchanged.In 2006, the Canadian province of Ontario implemented a new provincial NBS program that differs from conventional programs. One of the key differences is the structured and fully funded partnership between the ministry of health, the NBS laboratory, and the treatment centers in the province. Each one of these partners has defined roles and accountability. Another difference is the move away from the conventional recall process to an immediate referral system to selected treatment centers.In this article, we report our experience with the new screening structure and discuss it as a model for future NBS programs.

The use of liquid chromatography-tandem mass spectrometry in newborn screening for congenital adrenal hyperplasia: improvements and future perspectives. Front Endocrinol (Lausanne) 2023; 14:1226284.

Abstract
Newborn screening for congenital adrenal hyperplasia using 17-hydroxyprogesterone by immunoassay remains controversial despite screening been available for almost 40 years. Screening is confounded by poor immunoassay specificity, fetal adrenal physiology, stress, and illness which can result in a large number of false positive screening tests. Screening programmes apply higher screening thresholds based on co-variates such as birthweight or gestational age but the false positive rate using immunoassay remains high. Mass spectrometry was first applied to newborn screening for congenital adrenal hyperplasia over 15 years ago. Elevated 17-hydroxprogesterone by immunoassay can be retested with a specific liquid chromatography tandem mass spectrometry assay that may include additional steroid markers. Laboratories register with quality assurance programme providers to ensure accurate steroid measurements. This has led to improvements in screening but there are additional costs and added laboratory workload. The search for novel steroid markers may inform further improvements to screening. Studies have shown that 11-oxygenated androgens are elevated in untreated patients and that the adrenal steroidogenesis backdoor pathway is more active in babies with congenital adrenal hyperplasia. There is continual interest in 21-deoxycortisol, a specific marker of 21-hydroxylase deficiency. The measurement of androgenic steroids and their precursors by liquid chromatography tandem mass spectrometry in bloodspots may inform improvements for screening, diagnosis, and treatment monitoring. In this review, we describe how liquid chromatography tandem mass spectrometry has improved newborn screening for congenital adrenal hyperplasia and explore how future developments may inform further improvements to screening and diagnosis.

Abstract
The assumption of this study is strictly connected to the need to focus and to know more about the impact on the psychological state of the parents whose newborn babies get a positive result at Expanded Newborn Screening (ENS). As clinical experience shows us, this aspect seems to have a potentially lasting resonance on the way the disease will be managed and handled in the family, leading to potential negative effects and repercussions on the child's wellbeing and on the quality of life within the family. On the basis of this and on the evidence emerging from a review of the literature, this study aims to investigate and objectify possible distress indicators elicited at the moment of the communication of a positive result at ENS. Questionnaires containing the Beck Depression Inventory-II, the State-Trait Anxiety Inventory-Y, and the Short Form 36 Health Survey tests were administered to the parents of 87 newborns who received positive results at ENS. The parents of 32 babies expressed the presence of discomfort potentially related to the communication of a positive result at ENS.

Abstract
Background As more than 500,000 neonates participate in newborn congenital hypothyroidism (CH) screening in Guangxi Zhuang Autonomous Region each year, the overall number of false-positive (FP) cases has increased. We aim to assess the parental stress in parents of neonates with FP CH results in Guangxi, find out the influence factors related to demographics, and provide the basis for personalized health education. Methods The parents of neonates with FP CH results were invited to participate in the FP group, and the parents of neonates with all negative results were invited to participate in the control group. The parents completed a questionnaire on demographics, knowledge of CH, and the parental stress index (PSI) in the hospital for the first time. The follow-up visits for PSI were conducted 3, 6, and 12 months afterward through telephone and online. Results A total of 258 and 1,040 parents participated in the FP and control groups, respectively. The parents in the FP group had better knowledge of CH and higher PSI scores than the parents in the control group. The result of logistic regression showed that the major influence factors related to the knowledge of CH were FP experience and source of knowledge. The parents in the FP group who were well-informed during the recall phone call had lower PSI scores than the other parents. The parents in the FP group showed decreasing PSI scores gradually in follow-up visits. Conclusion The results suggested that FP screening results may affect parental stress and parent-child relationship. FP results increased the stress on the parents and increased their knowledge of CH passively.

Abstract
Neonatal screening has excellent coverage in France. Data from the foreign literature raise questions about the informed consent to this screening. The Neonatal Screening and Informed Consent Dépistage Néonatal Information et Consentement Eclairé (DENICE) study was designed to assess whether information on neonatal screening provided for families in Brittany allows for informed consent. A qualitative methodology was chosen to collect parents' opinions on this topic. Twenty semi-structured interviews were conducted with twenty-seven parents whose children had positive neonatal screening for one of six diseases. The five main themes from the qualitative analysis were knowledge of neonatal screening, information received by parents, parental choice, the experience of the screening process, and parents' perspectives and wishes. Informed consent was weakened by parents' lack of knowledge regarding choice and the absence of a parent after birth. The study found that more information about screening during pregnancy would be preferable. The information should be repeated and accessible and should make it clear that neonatal screening is not mandatory, but informed consent should be obtained from parents who choose to screen their newborns.

Abstract
As a psychologist and an ethicist, we have explored empirically newborn screening consent and communication processes. In this paper we consider the impact on families if newborn screening uses whole genome sequencing. We frame this within the World Health Organization's definition of health and contend that proposals to use whole genome sequencing in newborn screening take into account the ethical, practical and psychological impact of such screening. We argue that the important psychological processes occurring in the neonatal phase necessitate a clear justification that providing risk information at this stage provides a health benefit. We illustrate how research on current newborn screening can inform whole genome sequencing debates, whilst highlighting important gaps. Obtaining explicit, voluntary, and sufficiently informed consent for newborn screening is challenging, however we stress that such consent is ethically and legally appropriate and psychologically and practically important. We conclude by outling how this might be done.

Evaluation of a New Laboratory Protocol for Newborn Screening for Congenital Adrenal Hyperplasia in New Zealand. Int J Neonatal Screen 2022; 8:ijns8040056. [PMID: 36278626 PMCID: PMC9590017 DOI: 10.3390/ijns8040056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Revised: 10/18/2022] [Accepted: 10/19/2022] [Indexed: 11/05/2022] Open
Abstract
Between 2005 and 2021, 49 cases of classical congenital adrenal hyperplasia were diagnosed in New Zealand, 39 were detected in newborns and 10 were not detected by screening. Currently, for every case of CAH detected by screening, 10 false-positive tests are encountered. Second-tier liquid chromatography-tandem mass spectrometry (LCMSMS) has the potential to improve screening sensitivity and specificity. A new laboratory protocol for newborn screening for CAH was evaluated. Birthweight-adjusted thresholds for first- and second-tier 17-hydroxyprogesterone, second-tier 21-deoxycortisol and a steroid ratio were applied to 4 years of newborn screening data. The study was enriched with 35 newborn screening specimens from confirmed CAH cases. Newborn screening was conducted on 232,542 babies, and 11 cases of classical CAH were detected between 2018 and 2021. There were 98 false-positive tests (specificity 99.96%, PPV = 10.1%) using the existing protocol. Applying the new protocol, the same 11 cases were detected, and there were 13 false-positive tests (sensitivity > 99.99%, PPV = 45.8%, (X2 test p < 0.0001). Incorporating the retrospective specimens, screening sensitivity for classical CAH was 78% (existing protocol), compared to 87% for the new protocol (X2 test p = 0.1338). Implementation of LCMSMS as a second-tier test will improve newborn screening for classical CAH in New Zealand.

Abstract
Genomic advances have contributed to a proliferation of newborn screening (NBS) programs. Psychosocial consequences of NBS have been identified as risks to these public health initiatives. Following PRISMA guidelines, this systematic review synthesizes findings from 92 evidence-based, peer-reviewed research reports published from 2000 through 2020 regarding psychosocial issues associated with NBS. Results describe parents' knowledge of and attitudes towards NBS, reactions to and understanding of positive NBS results, experiences of communication with health providers, decisions about carrier testing, and future pregnancies. Findings also explain the impact of positive NBS results on parent-child relationships, child development, informing children about carrier status, family burden, quality of life, and disparities. In conclusion, psychosocial consequences of receiving unexpected neonatal screening results and unsolicited genetic information remain significant risks to expansion of NBS. Findings suggest that risks may be mitigated by improved parent NBS education, effective communication, individualized genetic counseling, and anticipatory developmental guidance. Clinicians need to take extra measures to ensure equitable service delivery to marginalized subpopulations. Future investigations should be more inclusive of culturally and socioeconomically diverse families and conducted in low-resource countries. Providing these countries with adequate resources to develop NBS programs is an essential step towards achieving international health equity.

A Simple Flow Injection Analysis-Tandem Mass Spectrometry Method to Reduce False Positives of C5-Acylcarnitines Due to Pivaloylcarnitine Using Reference Ions. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9050694.

Abstract
Flow injection analysis−tandem mass spectrometry (FIA-TMS) has been applied in a first-tier test of newborn screening (NBS). Although isovalerylcarnitine (i-C5), which is a diagnostic indicator of isovaleric acidemia (IVA), is isobaric with pivaloylcarnitine (p-C5), 2-methylbutyrylcarnitine, and n-valerylcarnitine, these isomers cannot be distinguished by the FIA-TMS. There are many reports of false positives derived from p-C5 due to the use of pivalate-conjugated antibiotics. In this study, we developed a new FIA-TMS method to distinguish i-C5 and p-C5. We found that the intensity ratio of product ions for i-C5 and p-C5 was different in a certain range even under the same analytical conditions. The product ions with the most distinct differences in ionic intensity between the isomers and the collision energies that produce them were determined to be m/z 246.2 > 187.1 and −15 V, respectively. In addition to the quantification ion, a reference ion was defined, and the similarity of the i-C5 and p-C5 reference ion ratios (i-C5 score and p-C5 score, respectively) were used to estimate which isomer (i-C5 and p-C5) was responsible for elevated C5 acylcarnitine in dried blood spots (DBSs). As a result of analyses of 11 DBS samples derived from pivalate-conjugated antibiotics and four DBS samples from IVA patients using our method, it was found that our method was able to correctly determine the type of C5-acylcarnitine (i-C5 or p-C5) in the DBS samples. Implementation of this new FIA-TMS method into the current NBS protocol will allow for a reduction in false positives in IVA.

Abstract
Newborn screening (NBS) programmes are considered to be one of the most successful secondary prevention measures in childhood to prevent or reduce morbidity and/or mortality via early disease identification and subsequent initiation of therapy. However, while many rare diseases can now be detected at an early stage using appropriate diagnostics, the introduction of a new target disease requires a detailed analysis of the entire screening process, including a robust scientific background, analytics, information technology, and logistics. In addition, ethics, financing, and the required medical measures need to be considered to allow the benefits of screening to be evaluated at a higher level than its potential harm. Infantile nephropathic cystinosis (INC) is a very rare lysosomal metabolic disorder. With the introduction of cysteamine therapy in the early 1980s and the possibility of renal replacement therapy in infancy, patients with cystinosis can now reach adulthood. Early diagnosis of cystinosis remains important as this enables initiation of cysteamine at the earliest opportunity to support renal and patient survival. Using molecular technologies, the feasibility of screening for cystinosis has been demonstrated in a pilot project. This review aims to provide insight into NBS and discuss its importance for nephropathic cystinosis using molecular technologies.

Newborn Screening for X-Linked Adrenoleukodystrophy: Review of Data and Outcomes in Pennsylvania. Int J Neonatal Screen 2022; 8:ijns8020024.

Abstract
X-linked adrenoleukodystrophy (X-ALD) is the most common peroxisomal disorder. It results from pathogenic variants in ABCD1, which encodes the peroxisomal very-long-chain fatty acid transporter, causing a spectrum of neurodegenerative phenotypes. The childhood cerebral form of the disease is particularly devastating. Early diagnosis and intervention improve outcomes. Because newborn screening facilitates identification of at-risk individuals during their asymptomatic period, X-ALD was added to the Pennsylvania newborn screening program in 2017. We analyzed outcomes from the first four years of X-ALD newborn screening, which employed a two-tier approach and reflexive ABCD1 sequencing. There were 51 positive screens with elevated C26:0-lysophosphatidylcholine on second-tier screening. ABCD1 sequencing identified 21 hemizygous males and 24 heterozygous females, and clinical follow up identified four patients with peroxisomal biogenesis disorders. There were two false-positive cases and one false-negative case. Three unscreened individuals, two of whom were symptomatic, were diagnosed following their young siblings' newborn screening results. Combined with experiences from six other states, this suggests a U.S. incidence of roughly 1 in 10,500, higher than had been previously reported. Many of these infants lack a known family history of X-ALD. Together, these data highlight both the achievements and challenges of newborn screening for X-ALD.

Abstract
Congenital adrenal hyperplasia is a category of disorders characterized by impaired
adrenocortical steroidogenesis. The most frequent disorder of congenital adrenal
hyperplasia is 21-hydroxylase deficiency, which is caused by pathogenic variants of
CAY21A2 and is prevalent between 1 in 18,000 and 20,000 in Japan. The
clinical guidelines for 21-hydroxylase deficiency in Japan have been revised twice since a
diagnostic handbook in Japan was published in 1989. On behalf of the Japanese Society for
Pediatric Endocrinology, the Japanese Society for Mass Screening, the Japanese Society for
Urology, and the Japan Endocrine Society, the working committee updated the guidelines for
the diagnosis and treatment of 21-hydroxylase deficiency published in 2014, based on
recent evidence and knowledge related to this disorder. The recommendations in the updated
guidelines can be applied in clinical practice considering the risks and benefits to each
patient.

Second Tier Testing to Reduce the Number of Non-actionable Secondary Findings and False-Positive Referrals in Newborn Screening for Severe Combined Immunodeficiency. J Clin Immunol 2021; 41:1762-1773.

Abstract
PURPOSE Newborn screening (NBS) for severe combined immunodeficiency (SCID) is based on the detection of T-cell receptor excision circles (TRECs). TRECs are a sensitive biomarker for T-cell lymphopenia, but not specific for SCID. This creates a palette of secondary findings associated with low T-cells that require follow-up and treatment or are non-actionable. The high rate of (non-actionable) secondary findings and false-positive referrals raises questions about the harm-benefit-ratio of SCID screening, as referrals are associated with high emotional impact and anxiety for parents. METHODS An alternative quantitative TREC PCR with different primers was performed on NBS cards of referred newborns (N = 56) and epigenetic immune cell counting was used as for relative quantification of CD3 + T-cells (N = 59). Retrospective data was used to determine the reduction in referrals with a lower TREC cutoff value or an adjusted screening algorithm. RESULTS When analyzed with a second PCR with different primers, 45% of the referrals (25/56) had TREC levels above cutoff, including four false-positive cases in which two SNPs were identified. With epigenetic qPCR, 41% (24/59) of the referrals were within the range of the relative CD3 + T-cell counts of the healthy controls. Lowering the TREC cutoff value or adjusting the screening algorithm led to lower referral rates but did not prevent all false-positive referrals. CONCLUSIONS Second tier tests and adjustments of cutoff values or screening algorithms all have the potential to reduce the number of non-actionable secondary findings in NBS for SCID, although second tier tests are more effective in preventing false-positive referrals.

Abstract
IMPORTANCE Newborn genomic sequencing (nGS) may provide health benefits throughout the life span, but there are concerns that it could also have an unfavorable (ie, negative) psychosocial effect on families. OBJECTIVE To assess the psychosocial effect of nGS on families from the BabySeq Project, a randomized clinical trial evaluating the effect of nGS on the clinical care of newborns from well-baby nurseries and intensive care units. DESIGN, SETTING, AND PARTICIPANTS In this randomized clinical trial conducted from May 14, 2015, to May 21, 2019, at well-baby nurseries and intensive care units at 3 Boston, Massachusetts, area hospitals, 519 parents of 325 infants completed surveys at enrollment, immediately after disclosure of nGS results, and 3 and 10 months after results disclosure. Statistical analysis was performed on a per-protocol basis from January 16, 2019, to December 1, 2019. INTERVENTION Newborns were randomized to receive either standard newborn screening and a family history report (control group) or the same plus an nGS report of childhood-onset conditions and highly actionable adult-onset conditions (nGS group). MAIN OUTCOMES AND MEASURES Mean responses were compared between groups and, within the nGS group, between parents of children who received a monogenic disease risk finding and those who did not in 3 domains of psychosocial impact: parent-child relationship (Mother-to-Infant Bonding Scale), parents' relationship (Kansas Marital Satisfaction Scale), and parents' psychological distress (Edinburgh Postnatal Depression Scale anxiety subscale). RESULTS A total of 519 parents (275 women [53.0%]; mean [SD] age, 35.1 [4.5] years) were included in this study. Although mean scores differed for some outcomes at singular time points, generalized estimating equations models did not show meaningful differences in parent-child relationship (between-group difference in adjusted mean [SE] Mother-to-Infant Bonding Scale scores: postdisclosure, 0.04 [0.15]; 3 months, -0.18 [0.18]; 10 months, -0.07 [0.20]; joint P = .57) or parents' psychological distress (between-group ratio of adjusted mean [SE] Edinburgh Postnatal Depression Scale anxiety subscale scores: postdisclosure, 1.04 [0.08]; 3 months, 1.07 [0.11]; joint P = .80) response patterns between study groups over time for any measures analyzed in these 2 domains. Response patterns on one parents' relationship measure differed between groups over time (between-group difference in adjusted mean [SE] Kansas Marital Satisfaction Scale scores: postdisclosure, -0.19 [0.07]; 3 months, -0.04 [0.07]; and 10 months, -0.01 [0.08]; joint P = .02), but the effect decreased over time and no difference was observed on the conflict measure responses over time. We found no evidence of persistent negative psychosocial effect in any domain. CONCLUSIONS AND RELEVANCE In this randomized clinical trial of nGS, there was no persistent negative psychosocial effect on families among those who received nGS nor among those who received a monogenic disease risk finding for their infant.

Abstract
OBJECTIVE Premature infants are known to have a higher rate of false positive newborn screening (NBS) results, with TPN as a contributing factor. The purpose of this quality improvement (QI) project is to reduce false positive NBS results via a TPN interruption protocol. METHODS A multidisciplinary team reviewed the literature and developed a new NBS collection protocol, which was implemented in 2 periods. In period 1, TPN was interrupted for 4 hours before NBS sample collection and initiation of carnitine supplements was avoided. In period 2, TPN was interrupted for 6 hours for infants birth weight (BW) < 1000 g, carnitine supplementation continued to be avoided. The rates of false positives NBS results were compared pre- and post-interventions in periods 1 and 2. RESULTS Four hundred twelve neonates were evaluated prior to implementation of this QI project (July 2013-June 2014) and 414 during period 1 intervention (July 2014-June 2016). False positive results decreased from 20.6% to 11.4% (p < 0.001) among all BW categories following the 4-hour TPN interruption. The rate of false positives was further reduced among infants < 1000 g (p = 0.035) in period 2 (n = 112), including a significant reduction in false positive results with elevated amino acid profiles (p = 0.005). CONCLUSIONS The implementation of a strict NBS collection protocol reduced false positive NBS results, which potentially can improve patient care by reducing unnecessary laboratory draws, pain, and parental anxiety. Interruption of TPN for 6 hours was significant in reducing NBS false positive results in neonates < 1000 g.

Abstract
Historically, the analyses used for newborn screening (NBS) were biochemical, but increasingly, molecular genetic analyses are being introduced in the workflow. We describe the application of molecular genetic analyses in the Danish NBS programme and show that second-tier molecular genetic testing is useful to reduce the false positive rate while simultaneously providing information about the precise molecular genetic variant and thus informing therapeutic strategy and easing providing information to parents. When molecular genetic analyses are applied as second-tier testing, valuable functional data from biochemical methods are available and in our view, such targeted NGS technology should be implemented when possible in the NBS workflow. First-tier NGS technology may be a promising future possibility for disorders without a reliable biomarker and as a general approach to increase the adaptability of NBS for a broader range of genetic diseases, which is important in the current landscape of quickly evolving new therapeutic possibilities. However, studies on feasibility, sensitivity, and specificity are needed as well as more insight into what views the general population has towards using genetic analyses in NBS. This may be sensitive to some and could have potentially negative consequences for the NBS programme.

Implementing steroid profiling by liquid chromatography-tandem mass spectrometry improves newborn screening for congenital adrenal hyperplasia in New Zealand. Clin Endocrinol (Oxf) 2021; 94:904-912. [PMID: 33471388 DOI: 10.1111/cen.14422] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2020] [Revised: 12/17/2020] [Accepted: 01/11/2021] [Indexed: 02/02/2023]
Abstract
OBJECTIVE To evaluate the impact of a liquid chromatography-tandem mass spectrometry (LCMSMS) second-tier test on newborn screening for congenital adrenal hyperplasia due to 21-hydroxylase deficiency (CAH) in New Zealand. DESIGN In a prospective study, a LCMSMS method to measure 17-hydroxyprogesterone (17OHP) was adapted to measure four additional steroids. Steroid concentrations were collected on all second-tier CAH screening tests while protocols remained unchanged. Steroid ratio parameters with recommended or published screening cuts-offs were evaluated for their impact on newborn screening performance. MEASUREMENTS Precision, accuracy, linearity and recovery of the second-tier LCMSMS method were evaluated. Second-tier specimens were divided in 3 groups; newborn screening bloodspots from neonates with confirmed CAH (n = 7) and 2 groups specimens from neonates with a birthweight (BW) ≤1500 g (n = 795) and with a BW > 1500 g (n = 806) with a negative newborn screening test. Six protocols using four steroid ratio parameters were evaluated. The sensitivity, specificity, false positive rate and positive predictive value of screening was calculated for each protocol. RESULTS The LCMSMS method was sufficiently accurate and precise to be used as a second-tier test for CAH. Screening sensitivity remained at 100% for each protocol apart from (17OHP + androstenedione)/cortisol when the highest cut-off of 3.75 was applied. The false positive rate was significantly improved when (17OHP + androstenedione)/cortisol and (17OHP + 21-deoxycortisol)/cortisol were evaluated with cut-offs of 2.5 and 1.5 respectively (P < .01) and both with a positive predictive value of 64%. CONCLUSIONS A second-tier LCMSMS newborn screening test for CAH offers significant improvements to screening specificity without any other changes to screening protocols.

Abstract
Newborn screening is a public health care program worldwide to prevent patients from critical illness or conditions. Tandem mass spectrometry allows multiplex, inexpensive, and rapid newborn screening. However, mass spectrometry used for newborn screening to date is not able to separate peaks of compounds with similar m/z, which could lead to false-positive results without additional second-tier tests, such as fragmentation. We experienced three neonatal cases with high levels of markers, octanoylcarnitine and octanoylcarnitine/decanoylcarnitine ratio used to pick up possible cases of medium-chain acyl-CoA dehydrogenase (MCAD) deficiency. The babies were born consecutively in a maternity hospital. Their second acylcarnitine profiles were normal, and the genetic tests for ACADM were negative. Analysis of samples extracted from their first Guthrie cards where blood was not stained also showed peaks equivalent to octanoylcarnitine and decanoylcarnitine, indicating contamination. Environmental surveillance in the maternity ward suggested that essential oils used there might contain the contaminated compound. LC-HRMS/MS and in silico analysis revealed that false-positive results might be due to contamination with the essential oils in Guthrie cards, and causal agents were sphinganine (d17:0) and 2-[2-hydroxyethyl(pentadecyl)amino]ethanol. Thus, health care providers should be cautioned about use of essential oils when collecting blood samples on Guthrie cards. False-positive results can waste costly social resources and cause a physical and psychological burden for children and parents.

Development of Strategies to Decrease False Positive Results in Newborn Screening. Int J Neonatal Screen 2020; 6:ijns6040084.

Abstract
The expansion of national newborn screening (NBS) programmes has provided significant benefits in the diagnosis and early treatment of several rare, heritable conditions, preventing adverse health outcomes for most affected infants. New technological developments have enabled the implementation of testing panel covering over 50 disorders. Consequently, the increment of false positive rate has led to a high number of healthy infants recalled for expensive and often invasive additional testing, opening a debate about the harm-benefit ratio of the expanded newborn screening. The false-positive rate represents a challenge for healthcare providers working in NBS systems. Here, we give an overview on the most commonly used strategies for decreasing the adverse effects due to inconclusive screening results. The focus is on NBS performance improvement through the implementation of analytical methods, the application of new and more informative biomarkers, and by using post-analytical interpretive tools. These strategies, used as part of the NBS process, can to enhance the positive predictive value of the test and reduce the parental anxiety and healthcare costs related to the unnecessary tests and procedures.

Abstract
Newborn screening (NBS) is an important part of public healthcare systems in many countries. The provision of information to parents about NBS is now recognised as an integral part of the screening process. Informing parents on all aspects of screening helps to achieve the benefits, promote trust and foster support for NBS. Therefore, policies and guidelines should exist to govern how the information about NBS is provided to parents, taking into account evidence-based best practices. The purpose of our survey was to explore whether any legally binding provisions, guidelines or recommendations existed pertaining to the provision of information about NBS to parents across Europe. Questions were designed to determine the regulatory process of when, by whom and how parents should be informed about screening. Twenty-seven countries participated in the survey. The results indicated that most countries had some sort of legal framework or guidelines for the provision of information to parents. However, only 37% indicated that the provision of information was required prenatally. The majority of countries were verbally informing parents with the aid of written materials postnatally, just prior to sample collection. Information was provided by a neonatologist, midwife or nurse. A website dedicated to NBS was available for 67% of countries and 89% had written materials about NBS for parents. The survey showed that there is a lack of harmonisation among European countries in the provision of information about NBS and emphasised the need for more comprehensive guidelines at the European level.

Abstract
OBJECTIVES To measure parental perceptions of child vulnerability, as a precursor to developing a population-scale mechanism to mitigate harm after newborn screening. STUDY DESIGN Participants were parents of infants aged 2-5 months. Parental perceptions of child vulnerability were assessed with an adapted version of the Vulnerable Baby Scale. The scale was included in the script for a larger study of telephone follow-up for 2 newborn blood screening samples (carrier status for cystic fibrosis or sickle cell hemoglobinopathy). A comparison sample was added using a paper survey with well-baby visits to an urban/suburban clinic. RESULTS Sample sizes consisted of 288 parents in the cystic fibrosis group, 426 in the sickle cell hemoglobinopathy group, and 79 in the clinic comparison group. Parental perceptions of child vulnerability were higher in the sickle cell group than cystic fibrosis group (P < .0001), and both were higher than the clinic comparison group (P < .0001). Parental perceptions of child vulnerability were inversely correlated with parental age (P < .002) and lower health literacy (P < .015, sickle cell hemoglobinopathy group only). CONCLUSIONS Increased parental perceptions of child vulnerability seem to be a bona fide complication of incidental newborn blood screening findings, and healthcare professionals should be alert to the possibility. From a public health perspective, we recommend routine follow-up after incidental findings to mitigate psychosocial harm.

Abstract
OBJECTIVE To conduct interviews with a multiyear sample of parents of infants found to have heterozygous status for sickle cell hemoglobinopathy or cystic fibrosis during newborn blood screening (NBS). STUDY DESIGN Interviewers with clinical backgrounds telephoned parents, and followed a structured script that blended follow-up and research purposes. Recruiting followed several steps to minimize recruiting bias as much as possible for a NBS study. RESULTS Follow-up calls were conducted with parents of 426 infant carriers of sickle cell hemoglobinopathy, and 288 parents of cystic fibrosis carriers (34.8% and 49.6% of those eligible). Among these, 27.5% and 7.8% had no recollection of being informed of NBS results. Of those who recalled a provider explanation, 8.6% and 13.0% appraised the explanation negatively. Overall, 7.4% and 13.2% were dissatisfied with the experience of learning about the NSB result. Mean anxiety levels were low but higher in the sickle cell hemoglobinopathy group (P < .001). Misconceptions that the infant might get the disease were present in 27.5% and 7.8% of parents (despite zero actual risk for disease). Several of these data were significantly predicted by NBS result, health literacy, parental age, and race/ethnicity factors. CONCLUSIONS Patient-centered public health follow-up can be effective after NBS identifies carrier status. Psychosocial complications were uncommon, but harms were substantial enough to justify mitigation.

Endocr Metab Immune Disord Drug Targets 2020; 21:966-969.

Abstract
BACKGROUND AND AIM Although it is widely known that the total parenteral nutrition (TPN) used frequently in intensive care units has unwanted side effects, there is little known about how it interferes with the amino acid levels taken during the diagnosis of metabolic diseases. Amino acid can lead to inaccurate measurements with mass spectrometry due to its high molecular content of lipids and carbohydrates, which modifies the blood matrix. The purpose of this study was to emphasize the results of amino acid interference, measured with mass spectrometry, in patients administered with TPN. CASE PRESENTATION Incorrect clinical interpretation resulted in the case of a pneumonia patient with false positive and negative blood amino acid levels caused by TPN infusion. The amino acid profile had been requested to rule out an amino acid metabolic defect in the two-year-old boy who arrived at the pediatric clinic complaining of respiratory distress, tachypnea and hypoxemia. He was monitored in the intensive care unit for further investigation. The personnel who had performed phlebotomy also carried out the sampling during the TPN infusion administration. This caused the amino acid results and an incorrect interpretation. The following deviation ratios were detected: phenylalanine 102%, leucine 86%, isoleucine 106%, GABA 200%, citrulline 238%, glutamine 178%, ornithine 216%, 1- methyl-l-histidine 1471%, serine 312%, alanine 163%, glycine 355%, homocitrulline and carnosine 444%. The amino acid blood level measurements taken for diagnosis and screening in suspected metabolic disease may lead to involuntary false low or elevated results in patients administered with TPN. CONCLUSION This case demonstrates that TPN solutions affect the reference method of mass spectrometry measurement methods due to the concentration of ingredients. We suggest that inaccurate results can be avoided by carrying out the sampling prior to TPN infusion in patients whose plasma amino acid levels will be measured.

Abstract
Very-long-chain acyl-CoA dehydrogenase (VLCAD) deficiency, a condition in which the body is unable to break down long-chain fatty acids properly, is the most common fatty acid oxidation disorder in Japan. Tandem mass spectrometry has been used in newborn screening (NBS), allowing the detection of patients with VLCAD deficiency even before symptoms manifest. However, tandem mass spectrometry has a high false positive rate. We investigated the clinical characteristics of patients with false positive results for tetradecenoyl acylcarnitine (C14:1). This case-control study used data collected between the 1st of January 2014 and the 31st of March 2019. The case group was defined as patients having levels of both C14:1 and C14:1/C2 ratio higher than cut-off levels in the first newborn mass screening, who were eventually diagnosed as false positives by attending doctors at Kobe University Hospital, Palmore Hospital, or Kakogawa Central City Hospital in Japan. The control group comprised 100 patients randomly selected from the three facilities. The false positive group included 17 cases, and the control group contained 300 patients. The demographics of each group did not show any significant differences in sex, body weight at birth, Cesarean section rate, complete breastfeeding rate, or the number of feedings per day. However, the change in body weight at the sampling day of NBS in the false positive and control groups was -10.2%, and - 4.6%, respectively, showing a statistically significant difference (p < 0.01). In addition, body weight gain at the one-month medical checkup was 38.9 g/day in the false positive group and 44.1 g/day in the control group (p < 0.05). An elevation of C14:1 carnitine has been reported in situations involving the catalysis of fatty acid. Therefore, patients with severe body weight loss might be associated with poor sucking or poor milk supply, which might cause a false positive elevation of C14:1 and C14:1/C2. In suspected VLCAD deficiency, attending doctors should pay attention to body weight changes recorded during newborn mass screening.

Abstract
Sweden has one neonatal screening laboratory, receiving 115 to 120 thousand samples per year. Among the one million babies screened by tandem mass spectrometry from November 2010 until July 2019, a total of 665 babies were recalled and 311 verified as having one of the diseases screened for with this methodology, giving a positive predictive value (PPV) of 47% and an incidence of 1:3200. The PPV was high (41%) already in the first year after start of screening, thanks to the availability of the collaborative project Region 4 Stork database. The PPV is presently 58%. This improvement was achieved by the implementation of second-tier analyses in the screening for methylmalonic aciduria, propionic aciduria, isovaleric aciduria, and homocystinuria, and the employment of various post analytical tools of the Region 4 Stork, and its successor the collaborative laboratory integrated reports.

Wright EL, Baker PR. Neonatal Macrosomia is an Interfering Factor for Analytes on the Colorado State Newborn Screen. J Clin Endocrinol Metab 2020; 105:5775549. [PMID: 32126138 DOI: 10.1210/clinem/dgz183] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2019] [Accepted: 11/05/2019] [Indexed: 01/26/2023]
Abstract
PURPOSE Neonatal macrosomia is a known complication of maternal obesity and gestational diabetes, and it is a risk factor for obesity and diabetes in offspring. Amino acids and acylcarnitines are biomarkers for obesity in children and adults. These analytes, which are also routinely obtained on the newborn screen, have not been well-characterized in macrosomic newborns. The impact of macrosomia on rates of false-positive results in the newborn screen has also not been well-studied. We test the hypothesis that macrosomia is an interfering factor for amino acids and/or acylcarnitines on the newborn screen. METHODS Newborn screening analytes determined by tandem mass spectroscopy were obtained from the Colorado Department of Public Health and Environment archives (2016-2018). This included metabolite concentrations obtained at 24-72 hours of life from newborns with birth weight 2500 to 3999 g (nonmacrosomic, n = 131 896) versus 4000 to 8000 g (macrosomic, n = 7806). Mother/infant phenotypic data were limited to information provided on the newborn screening dried blood spot card. Data were analyzed using Student t-test and chi-squared analysis. RESULTS Macrosomic newborns had elevations in C2, C3, dicarboxylic, and long-chain acylcarnitines (specifically C16 and C18 species). C3 and C18:1 were 2 to 3 times more likely to be above predetermined state cutoffs in macrosomic versus nonmacrosomic newborns (both male and female). MAIN CONCLUSIONS Macrosomia is an interfering factor for the analytes C3 and C18:1, leading to higher risk of false-positive results for methylmalonic/propionic acidemia and carnitine palmitoyl transferase type 2 deficiency, respectively. Analyte patterns found in macrosomic neonates correspond with similar analyte patterns in obese children and adults.

Measurement of 17-Hydroxyprogesterone by LCMSMS Improves Newborn Screening for CAH Due to 21-Hydroxylase Deficiency in New Zealand. Int J Neonatal Screen 2020; 6:6. [PMID: 33073005 PMCID: PMC7422986 DOI: 10.3390/ijns6010006] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/24/2019] [Accepted: 01/24/2020] [Indexed: 11/26/2022] Open
Abstract
The positive predictive value of newborn screening for congenital adrenal hyperplasia due to 21-hydroxylase deficiency was <2% in New Zealand. This is despite a bloodspot second-tier immunoassay method for 17-hydroxyprogesterone measurement with an additional solvent extract step to reduce the number of false positive screening tests. We developed a liquid chromatography tandem mass spectrometry (LCMSMS) method to measure 17-hydroxyprogesterone in bloodspots to replace our current second-tier immunoassay method. The method was assessed using reference material and residual samples with a positive newborn screening result. Correlation with the second-tier immunoassay was determined and the method was implemented. Newborn screening performance was assessed by comparing screening metrics 2 years before and 2 years after LCMSMS implementation. Screening data analysis demonstrated the number of false positive screening tests was reduced from 172 to 40 in the 2 years after LCMSMS implementation. The positive predictive value of screening significantly increased from 1.71% to 11.1% (X2 test, p < 0.0001). LCMSMS analysis of 17OHP as a second-tier test significantly improves screening specificity for CAH due to 21-hydroxylase deficiency in New Zealand.

Effect of blood volume on analytical bias in dried blood spots prepared for newborn screening external quality assurance. Bioanalysis 2020; 12:99-109. [DOI: 10.4155/bio-2019-0201] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/17/2022] Open
Abstract
Aim: Dried blood spots (DBS) are used for the analysis of more than 2000 biomarkers. We assessed a range of analyte concentrations and diameters of DBS. Materials & methods: DBS samples were created by the application of increasing volumes of whole blood prepared by the UK NEQAS Quality Assurance Laboratory. Samples were analyzed in four separate laboratories. Results: Volumes less than 25 μl (8 mm) and more than 75 μl (14 mm) created unsatisfactory analytical biases. Results obtained from peripheral subpunches tended to be higher than those from a central subpunch. Conclusion: DBS diameters formed from nonvolumetric application of blood to filter paper can be used to assess whether measurement bias will be within acceptable limits according to the analyte being quantified. DBS received for newborn screening in the UK with diameters less than 8 mm and those more than 14 mm should be rejected.

Abstract
Appropriate and timely education about newborn screening (NBS) helps to foster benefits such as prompt follow up, to promote parents' autonomy via informed consent and minimize the harms such as reducing the impact of NBS false-positive results. The aim of this study was to ascertain how mothers are informed about NBS in the Czech Republic and to identify the variables associated with awareness about NBS. The questionnaires evaluating awareness and its determinants were mailed to a random sample of 3000 mothers 3 months post-delivery. The overall response rate was 42%. We analysed 1100 questionnaires and observed that better awareness about NBS was significantly associated with age, parity, number of information sources, child health status, size of maternity hospital and an obstetrician as the source of prenatally obtained information. Although the majority of mothers (77%) in our study recalled being informed by a physician or nurse in the neonatal ward, results have revealed that over 40% of participants did not have sufficient awareness about the principal aspects of NBS. Several measures including seminars for healthcare providers and the development and distribution of new educational materials were adopted to improve parental education about NBS in the Czech Republic.

Abstract
In Germany, screening for cystic fibrosis (CF) is part of the newborn screening since September 2016. The risk of psychological harm due to false-positive screening results is a longstanding concern. We investigated the parents' perception of the CF screening process in Bavaria and the communication after positive screening results with a questionnaire. Until August 2018, 192 children went through a final diagnostic testing after a positive CF screening result, and 105 (54.7%) families completed the questionnaire. Of these, only 30 parents obtained information about the newborn screening by a physician, despite this being mandatory in Germany. Parents being informed by a CF specialist (28.6%) about the positive screening result were more satisfied with the given information (80.0 versus 50% informed by the maternity ward), and the delay until the final diagnostic testing was shorter. More than 3 days between the information about the screening result and the diagnostic testing was too long for 77.7% of the families.Conclusion: Performing final diagnostic testing with only short delays and receiving satisfactory information is important. Therefore, parents should be informed directly by a CF center about positive screening results and only when sweat testing is possible within the next days. What is Known: • The risk of psychological harm due to false-positive screening results is a longstanding concern. • Satisfactory information about the positive CF screening result seem to reduce the parental stress. What is New: • Parents being informed directly by a CF specialist were more satisfied with the given information and the delay until the final diagnostic testing was shorter. • Our data support the concept that parents should better be informed directly by a CF specialist about positive screening results and only when sweat testing is possible within the next days to reduce parental stress.

Abstract
AIM Early identification of communication disorders is important and may be possible through screening in the child health services. The aim of the study was to investigate nurses' experiences and sense of competence when using the Infant-Toddler Checklist (ITC) communication screening at the 18-month health visit. METHODS A mixed-methods design including three focus group interviews (n = 14) and a web-based survey (n = 22) among nurses using the ITC or the standard method. Interview data were analysed through systematic text condensation and a deductive analysis based on implementation theory. Groups were compared using Mann-Whitney tests. RESULT Three themes emerged: Using a structured evaluation of communication changes, the dynamic, ITC is a beneficial tool and Implementation of the ITC faces a few challenges. Nurses who used the ITC perceived to a greater extent that they used a structured method (p = 0.003, r = 0.9) and felt more secure in describing the child's communication and language development to parents (p = 0.006, r = 0.83) compared to the standard method group. CONCLUSION Using the ITC supported the nurses in their assessment of communication at 18 months. Nurses' sense of competence was higher when using the ITC, both in their assessment and in communicating with parents.

Abstract
Expanded newborn screening of inborn errors of metabolism (IEM) based on tandem mass spectrometry (MS/MS) technology is one of the most successful preventative healthcare initiatives for presymptomatic diagnosis and treatment of rare yet treatable genetic diseases in the population. However, confirmatory testing of presumptive screen-positive cases is required using high efficiency separations for improved specificity in order to improve the positive predictive value (PPV) for certain classes of IEMs. Here, we describe recent advances using capillary electrophoresis-mass spectrometry (CE-MS) for reliable second-tier screening or confirmatory testing based on targeted analysis of amino acids, acylcarnitines, nucleosides, and other classes of polar metabolites associated with IEMs. Additionally, nontargeted metabolite profiling enables the identification of unknown biomarkers of clinical significance for other genetic diseases that are currently screened by bioassays and/or mutation panels, such as cystic fibrosis (CF). Noteworthy, CE-MS allows for resolution of isobaric/isomeric interferences without complicated sample handling that is ideal when analyzing volume-restricted biospecimens from neonates/infants, including dried blood spots and sweat specimens. New developments to improve concentration sensitivity, as well as enhance sample throughput and quality control for unambiguous confirmatory testing of IEMs will also be discussed when using multiplexed separations based on multisegment injection-CE-MS.

Abstract
Pulse oximetry screening to detect hypoxaemia in newborn infants was introduced at birthing facilities in New Zealand during a feasibility study determining barriers and enablers to universal screening in a midwifery-led maternity system focused on community values and partnership with, and participation by, consumers. During the 2-year study period, parents of infants who underwent pulse oximetry screening were invited to complete a written survey to investigate consumer satisfaction. Respondents ranked their satisfaction with the test and with information resources on a five-level Likert scale. Additional comments were added in a free text space. Participation was voluntary and anonymous. A total of 657 surveys were included for analysis. Consumers were satisfied with the screening procedure; 94% either agreed or strongly agreed that it is an important health check. Although the quality of information sources was deemed good, a third of participants indicated a wish to obtain more information. Some participants stated that retention of information was an issue, reporting that they were fatigued following the birth. Consumers are receptive to pulse oximetry screening. Sharing information (while considering the receptivity of parents) and engaging the parents of newborn infants are factors that are paramount to the success of newborn screening initiatives.

Abstract
Background: Understanding preferences for information provision in
the context of health care service provision is challenging because of the
number of potential attributes that may influence preferences. This study aimed
to identify midwives’ preferences for the process and outcomes of information
provision in an expanded national newborn bloodspot screening program.
Design: A sample of practicing midwives completed a
hybrid-stated preference survey including a conjoint analysis (CA) and discrete
choice experiment to quantify preferences for the types of, and way in which,
information should be provided in a newborn bloodspot screening program. Six
conjoint analysis questions captured the impact of different types of
information on parents’ ability to make a decision, and 10 discrete choice
experiment questions identified preferences for four process attributes
(including parents’ ability to make a decision). Results: Midwives
employed by the UK National Health Service (n = 134) completed the survey. All
types of information content were perceived to improve parents’ ability to make
a decision except for the possibility of false-positive results. Late pregnancy
was seen to be the best time to provide information, followed by day 3
postbirth. Information before 20 weeks of pregnancy was viewed as reducing
parents’ ability to make a decision. Midwives preferred information to be
provided by an individual discussion and did not think parents should receive
information on the Internet. Conclusion: A hybrid stated preference
survey design identified that a wide variety of information should be provided
to maximize parents’ ability to make a decision ideally provided late in
pregnancy or on day 3 postbirth.

Abstract
BACKGROUND The evidence review processes for adding new conditions to state newborn screening (NBS) panels rely on data from pilot studies aimed at assessing the potential benefits and harms of screening. However, the consideration of ethical, legal, and social implications (ELSI) of screening within this research has been limited. This paper outlines important ELSI issues related to newborn screening policy and practices as a resource to help researchers integrate ELSI into NBS pilot studies. APPROACH Members of the Bioethics and Legal Workgroup for the Newborn Screening Translational Research Network facilitated a series of professional and public discussions aimed at engaging NBS stakeholders to identify important existing and emerging ELSI challenges accompanying NBS. RESULTS Through these engagement activities, we identified a set of key ELSI questions related to (1) the types of results parents may receive through newborn screening and (2) the initiation and implementation of NBS for a condition within the NBS system. CONCLUSION Integrating ELSI questions into pilot studies will help NBS programs to better understand the potential impact of screening for a new condition on newborns and families, and make crucial policy decisions aimed at maximized benefits and mitigating the potential negative medical or social implications of screening.

Abstract
BACKGROUND Participation in the UK Newborn Bloodspot Screening Programme (NBSP) requires parental consent but concerns exist about whether or not this happens in practice and the best methods and timing to obtain consent at reasonable cost. OBJECTIVES To collate all possible modes of prescreening communication and consent for newborn (neonatal) screening (NBS); examine midwives', screening professionals' and users' views about the feasibility, efficiency and impact on understanding of each; measure midwives' and parents' preferences for information provision; and identify key drivers of cost-effectiveness for alternative modes of information provision. DESIGN Six study designs were used: (1) realist review - to generate alternative communication and consent models; (2) qualitative interviews with parents and health professionals - to examine the implications of current practice for understanding and views on alternative models; (3) survey and observation of midwives - to establish current costs; (4) stated preference surveys with midwives, parents and potential future parents - to establish preferences for information provision; (5) economic analysis - to identify cost-effectiveness drivers of alternative models; and (6) stakeholder validation focus groups and interviews - to examine the acceptability, views and broader impact of alternative communication and consent models. SETTING Providers and users of NBS in England. PARTICIPANTS Study 2: 45 parents and 37 health professionals; study 3: 22 midwives and eight observations; study 4: 705 adults aged 18-45 years and 134 midwives; and study 6: 12 health-care professionals and five parents. RESULTS The realist review identified low parental knowledge and evidence of coercive consent practices. Interview, focus group and stated preference data suggested a preference for full information, with some valuing this more than choice. Health professionals preferred informed choice models but parents and health professionals queried whether or not current consent was fully informed. Barriers to using leaflets effectively were highlighted. All studies indicated that a 'personalised' approach to NBS communication, allowing parents to select the mode and level of information suited to their learning needs, could have added value. A personalised approach should rely on midwife communication and should occur in the third trimester. Overall awareness was identified as requiring improvement. Starting NBS communication by alerting parents that they have a choice to make and telling them that samples could be stored are both likely to enhance engagement. The methods of information provision and maternal anxiety causing additional visits to health-care professionals were the drivers of relative cost-effectiveness. Lack of data to populate an economic analysis, confirmed by value of information analysis, indicated a need for further research. LIMITATIONS There are some limitations with regard to the range of participants used in studies 2 and 3 and so caution should be exercised when interpreting some of the results. CONCLUSIONS This project highlighted the importance of focusing on information receipt and identified key communication barriers. Health professionals strongly preferred informed consent, which parents endorsed if they were made aware of sample storage. Uniform models of information provision were perceived as ineffective. A choice of information provision was supported by health professionals and parents, which both enhances cost-effectiveness and improves engagement, understanding and the validity of consent. Remaining uncertainties suggest that more research is needed before new communication modes are introduced into practice. Future research should measure the impact of the suggested practice changes (informing in third trimester, information toolkits, changed role of midwife).

Abstract
Newborn screening programs aim to achieve presymptomatic diagnosis of treatable disorders allowing for early initiation of medical care to prevent or reduce significant morbidity and mortality. Many of the conditions included in the newborn screening panels are inborn errors of metabolism; however, screening for endocrine, hematologic, immunologic, and cardiovascular diseases, and hearing loss is also included in many panels. Newborn screening tests are not diagnostic and therefore diagnostic testing is needed to confirm or exclude the suspected diagnosis. Further advancement in technology is expected to allow continuous expansion of newborn screening.

J Community Genet 2018; 10:41-50. [PMID: 29504050 DOI: 10.1007/s12687-018-0361-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2017] [Revised: 02/13/2018] [Accepted: 02/20/2018] [Indexed: 11/30/2022] Open
Abstract
This study examines the interface between newborn screening and prenatal diagnosis from the point-of-view of parents of screen-positive children. Many conditions covered by newborn screening represent classic (autosomal recessive) Mendelian disorders. Parents of screen-positive infants therefore often come to learn that they are carriers of the disease, and face a decision whether to test for it in future pregnancies. Semi-structured interviews were conducted in 2015-2017 with 34 Israeli parents whose child was screen positive. Three major themes emanated from the parents' attitudes toward prenatal testing for the disease in prospective hypothetical pregnancies: rejection of prenatal testing for the disease associated with the screen positive, and relying instead on newborn screening to reveal if a future baby is also sick (18/34, 53%); support of prenatal testing to get more information (7/34, 21%) and support of prenatal testing in order to abort in case of a test positive (9/34, 26%). We discuss the importance of newborn screening for reproductive decision-making, highlighting the arguments associated with positive and negative parental views of the possibility of having another child with the same condition associated with the screen-positive of the child that had already been born. The conclusions challenge the common assertion that parents pursue the dream of the "perfect child" through prenatal diagnosis that "naturally" leads to selective abortion. The diversity of views expressed by Israeli parents of screen-positive children highlights the diversity of normative scripts of "genetic responsibility" in the context of parenthood.

Psychosocial impact on mothers receiving expanded newborn screening results. Eur J Hum Genet 2018; 26:477-484. [PMID: 29379194 DOI: 10.1038/s41431-017-0069-z] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2017] [Revised: 10/20/2017] [Accepted: 11/18/2017] [Indexed: 01/01/2023] Open
Abstract
Expanded newborn screening (NBS) for genetic disorders has improved diagnosis of numerous treatable diseases, positively impacting children's health outcomes. However, research about the psychological impact of expanded NBS on families, especially mothers, has been mixed. Our study examined associations between maternal experiences of expanded NBS and subsequent psychosocial functioning and parenting stress in mothers whose infants received either true negative (TN), true positive (TP) or false positive (FP) results after a 4- to 6-month period. The Parenting Stress Index and the Depression, Anxiety and Stress Scale were used to assess symptoms of anxiety, stress and depression in 3 sets of mothers, whose infants received TN (n = 31), TP (n = 8) or FP (n = 18) results. Multivariate analyses of variance (MANOVA) results revealed no significant differences among these three groups of mothers regarding overall anxiety, stress and depression. However, FP mothers experienced lower levels of stress related to their own health compared to TN group. Two potential trends were also identified; results suggested TN mothers might experience higher levels of isolation than mothers in the TP group and that FP mothers might report higher stress levels in relation to spousal relationships compared to the TN group. FP mothers seemed to report similar or better levels of psychosocial functioning than TN mothers. Our findings are encouraging with respect to impacts of NBS on maternal well-being. We also identify key areas for improvement (parental education) and research (isolation and spousal relationships).

Healthcare professionals' and parents' experiences of the confirmatory testing period: a qualitative study of the UK expanded newborn screening pilot. BMC Pediatr 2017; 17:121. [PMID: 28482885 PMCID: PMC5422997 DOI: 10.1186/s12887-017-0873-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2016] [Accepted: 04/25/2017] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND With further expansion of the number of conditions for which newborn screening can be undertaken, it is timely to consider the impact of positive screening results and the confirmatory testing period on the families involved. This study was undertaken as part of a larger programme of work to evaluate the Expanded Newborn Screening (ENBS) programme in the United Kingdom (UK). It was aimed to determine the views and experiences of healthcare professionals (HCPs) and parents on communication and interaction during the period of confirmatory testing following a positive screening result. METHODS Semi-structured interviews were undertaken with parents of children who had received a positive ENBS result and HCPs who had been involved with the diagnosis and support of parents. Ten parents and 11 healthcare professionals took part in the in-depth interviews. Questions considered the journey from the positive screening result through confirmatory testing to a confirmed diagnosis and the communication and interaction between the parents and HCPs that they had been experienced. Key themes were identified through thematic analysis. RESULTS The results point to a number of elements within the path through confirmatory testing that are difficult for parents and could be further developed to improve the experience. These include the way in which the results are communicated to parents, rapid turnaround of results, offering a consistent approach, exploring interventions to support family relationships and reviewing the workload and scheduling implications for healthcare professionals. CONCLUSIONS As technology enables newborn screening of a larger number of conditions, there is an increasing need to consider and mediate the potentially negative effects on families. The findings from this study point to a number of elements within the path through confirmatory testing that are difficult for parents and could be further developed to benefit the family experience.

Abstract
BACKGROUND The national newborn bloodspot screening programs (NBSPs) are continually expanding to screen for more conditions. OBJECTIVES To quantify parents' preferences for information and the way in which this is provided in example NBSPs. METHODS A hybrid choice experiment, combining a conjoint analysis and a discrete choice experiment, was designed. A sample of current and future parents between the ages of 18 and 45 years was identified via an Internet panel. Respondents completed one of two survey versions (9 conditions and 20 conditions) comprising a validated measure of attitudes toward involvement in decision making, 6 CA questions (11 information attributes), 10 DCE questions (4 attributes: 3 process and the ability to make an informed decision), and demographic questions. RESULTS Of the 702 respondents who completed the survey, 58% were women, 48% were between 25 and 34 years old, and 48% were current parents. All types of information were identified to statistically significantly improve parents' ability to make a decision. Participants preferred taking an "active" role in decision making. Respondents to the 9-condition survey preferred information before 20 weeks (willingness to pay [WTP] £11.88; CI £5.56 to £19.53) and the 20-condition group after 20 weeks (WTP £15.91; CI £10.64 to £21.63). All respondents disliked receiving information 3 days after birth, with the 20-condition group also being averse to receiving it on day 5 (WTP -£11.20; CI -£18.40 to 5.72). Respondents in both groups preferred to receive their information in an individual discussion. CONCLUSIONS This study suggests that parents' preferences for receiving NBS information differ from how this information is given in current UK practice.

Abstract
BACKGROUND The Department of Health and Human Services (HHS) Advisory Committee on Heritable Disorders in Newborns and Children ("Advisory Committee") makes recommendations to the HHS Secretary regarding addition of new conditions to the national Recommended Uniform Screening Panel for newborns. The Advisory Committee's decision-making process includes assessing the net benefit of screening for nominated conditions, informed by systematic evidence reviews generated by an independent Condition Review Workgroup. The evidence base regarding harms associated with screening for specific conditions is often more limited than that for benefits. PROCEDURES The process for defining potential harms from newborn screening reviewed the frameworks from other public health evidence-based review processes, adapted to newborn screening by experts in systematic review, newborn screening programs and bioethics, with input from and approval by the Advisory Committee. MAIN FINDINGS To support the Advisory Committee's review of nominated conditions, the Workgroup has developed a standardized approach to evaluation of harms and relevant gaps in the evidence. Types of harms include the physical burden to infants; psychosocial and logistic burdens to families from screening or diagnostic evaluation; increased risk of medical treatment for infants diagnosed earlier than children with clinical presentation; delayed diagnosis from false negative results; psychosocial harm from false positive results; uncertainty of clinical diagnosis, age of onset or clinical spectrum; and disparities in access to diagnosis or therapy. CONCLUSIONS Estimating the numbers of children at risk, the magnitude, timing and likelihood of harms will be integrated into Workgroup reports to the Advisory Committee.

Abstract
PURPOSE OF REVIEW The purpose of this review is to summarize the development and recent advancements of newborn screening. RECENT FINDINGS Early initiation of medical care has modified the outcome for many disorders that were previously associated with high morbidity (such as cystic fibrosis, primary immune deficiencies, and inborn errors of metabolism) or with significant neurodevelopmental disabilities (such as phenylketonuria and congenital hypothyroidism). The new era of mass spectrometry and next generation sequencing enables the expansion of the newborn screen panel, and will help to address technical issues such as turnaround time, and decreasing false-positive and false-negative rates for the testing. SUMMARY The newborn screening program is a successful public health initiative that facilitates early diagnosis of treatable disorders to reduce long-term morbidity and mortality.

Abstract
OBJECTIVES research suggests that information provided to parents about newborn bloodspot screening (NBS) can be inconsistent. The majority of international NBS programmes recommend that parents should receive information about NBS in the antenatal period, however prior studies have mostly focused on postnatal women's knowledge, with no quantitative study of women's knowledge in the antenatal period conducted to date. Thus, the aim of this study was to determine if antenatal women received information about NBS in the antenatal period and to evaluate their knowledge and attitudes about NBS. DESIGN/PARTICIPANTS we conducted a cross-sectional study among antenatal attendees at three maternity hospitals in Ireland. A total of 662 antenatal women (≥36 weeks gestation) were recruited into the study (279 primiparous, 368 multiparous). Women were asked to complete a self reported knowledge and attitude questionnaire about NBS. FINDINGS primiparity (OR 2.75; 95% CI 1.65, 4.59) lower educational status (OR 1.79; 95% CI 1.02, 3.15) and not having private health insurance (OR 1.84; 95% CI 1.19, 2.85) were independently associated with poor NBS knowledge. Fourteen per cent of antenatal women recalled receiving an information leaflet about NBS, yet over 87 % reported that they would like more information. Thirty four per cent of women agreed that they understand everything they need to know about NBS. CONCLUSIONS/IMPLICATIONS FOR PRACTICE the process of providing women with information about NBS in the antenatal period is inconsistent; consequently their awareness about NBS is limited. To make an informed choice about NBS women require information to be provided in a more structured format. There are many missed opportunities in the antenatal period for maternity care providers to provide women with information about NBS. Our study recommends that healthcare providers should have a more formal and structured approach with regard to the provision of information about NBS in the antenatal period. This could be achieved by incorporating NBS education into antenatal education classes or through multimedia while women are waiting in the antenatal clinic. Healthcare providers may need education about the importance and benefits of providing women with information about NBS in the antenatal period.
