RESUMO
PRKACA-related, atrial defects-polydactyly-multiple congenital malformation syndrome is a recently described skeletal ciliopathy, which is caused by disease-causing variants in PRKACA. The primary phenotypic description includes atrial septal defects, and limb anomalies including polydactyly and short limbs. To date, only four molecularly proven patients have been reported in the literature with a recurrent variant, c.409G>A p.Gly137Arg in PRKACA. In this study, we report the fifth affected individual with the same variant and review the clinical features and radiographic findings of this rare syndrome.

BACKGROUND: Testicular descent is a physiological process regulated by many factors. Eventually, disturbances in the embryological/fetal development path facilitate the occurrence of scrotal hernia, a congenital malformation characterized by the presence of intestinal portions within the scrotal sac due to the abnormal expansion of the inguinal ring. In pigs, some genes have been related to this anomaly, but the genetic mechanisms involved remain unclear. This study aimed to investigate the expression profile of a set of genes potentially involved with the manifestation of scrotal hernia in the inguinal ring tissue. METHODS AND RESULTS: Tissue samples from the inguinal ring/canal of normal and scrotal hernia-affected male pigs with approximately 30 days of age were used. Relative expression analysis was performed using qPCR to confirm the expression profile of 17 candidate genes previously identified in an RNA-Seq study. Among them, the Myosin heavy chain 1 (MYH1), Desmin (DES), and Troponin 1 (TNNI1) genes were differentially expressed between groups and had reduced levels of expression in the affected animals. These genes encode proteins involved in the formation of muscle tissue, which seems to be important for increasing the resistance of the inguinal ring to the abdominal pressure, which is essential to avoid the occurrence of scrotal hernia. CONCLUSIONS: The downregulation of muscular candidate genes in the inguinal tissue clarifies the genetic mechanisms involved with this anomaly in its primary site, providing useful information for developing strategies to control this malformation in pigs and other mammals.

OBJECTIVE: To investigate the diagnostic yield of trio whole-genome sequencing (WGS) in fetuses with various congenital malformations referred to a tertiary center for prenatal diagnosis. METHODS: In this prospective study, 50 pregnancies with different congenital malformations, negative for trisomies and causative copy-number variants, were analyzed further with fetal-parental trio WGS analysis. Parents were eligible for inclusion if they accepted further investigation following the detection of isolated or multiple malformations on prenatal ultrasound. Cases with isolated increased nuchal translucency, gamete donation or multiple pregnancy were excluded. WGS with the Illumina Inc. 30× polymerase-chain-reaction-free short-read sequencing included analysis of single-nucleotide variants, insertions and deletions, structural variants, short tandem repeats and copy-number identification of SMN1 and SMN2 genes. RESULTS: A molecular diagnosis was achieved in 13/50 (26%) cases. Causative sequence variants were identified in 12 genes: FGFR3 (n = 2), ACTA1 (n = 1), CDH2 (n = 1), COL1A2 (n = 1), DHCR7 (n = 1), EYA1 (n = 1), FBXO11 (n = 1), FRAS1 (n = 1), L1CAM (n = 1), OFD1 (n = 1), PDHA1 (n = 1) and SOX9 (n = 1). The phenotypes of the cases were divided into different groups, with the following diagnostic yields: skeletal malformation (4/9 (44%)), multisystem malformation (3/7 (43%)), central nervous system malformation (5/15 (33%)) and thoracic malformation (1/10 (10%)). Additionally, two cases carried variants that were considered potentially clinically relevant, even though they were assessed as variants of uncertain significance, according to the guidelines provided by the American College of Medical Genetics and Genomics. Overall, we identified a causative or potentially clinically relevant variant in 15/50 (30%) cases. CONCLUSIONS: We demonstrate a diagnostic yield of 26% with clinical WGS in prenatally detected congenital malformations. This study emphasizes the benefits that WGS can bring to the diagnosis of fetal structural anomalies. It is important to note that causative chromosomal aberrations were excluded from our cohort before WGS. As chromosomal aberrations are a well-known cause of prenatally detected congenital malformations, future studies using WGS as a primary diagnostic test, including assessment of chromosomal aberrations, may show that the detection rate exceeds the diagnostic yield of this study. WGS can add clinically relevant information, explaining the underlying cause of the fetal anomaly, which will provide information concerning the specific prognosis of the condition, as well as estimate the risk of recurrence. A genetic diagnosis can also provide more reproductive choice for future pregnancies. © 2024 The Authors.

The DEEP cohort is the first population-based cohort of pregnant population in China that longitudinally documented drug uses throughout the pregnancy life course and adverse pregnancy outcomes. The main goal of the study aims to monitor and evaluate the safety of drug use through the pregnancy life course in the Chinese setting. The DEEP cohort is developed primarily based on the population-based data platforms in Xiamen, a municipal city of 5 million population in southeast China. Based on these data platforms, we developed a pregnancy database that documented health care services and outcomes in the maternal and other departments. For identifying drug uses, we developed a drug prescription database using electronic healthcare records documented in the platforms across the primary, secondary and tertiary hospitals. By linking these two databases, we developed the DEEP cohort. All the pregnant women and their offspring in Xiamen are provided with health care and followed up according to standard protocols, and the primary adverse outcomes - congenital malformations - are collected using a standardized Case Report Form. From January 2013 to December 2021, the DEEP cohort included 564,740 pregnancies among 470,137 mothers, and documented 526,276 live births, 14,090 miscarriages and 6,058 fetal deaths/stillbirths and 25,723 continuing pregnancies. In total, 13,284,982 prescriptions were documented, in which 2,096 chemicals drugs, 163 biological products, 847 Chinese patent medicines and 655 herbal medicines were prescribed. The overall incidence rate of congenital malformations was 2.0% (10,444/526,276), while there were 25,526 (4.9%) preterm births and 25,605 (4.9%) live births with low birth weight.

BACKGROUND AND AIM: Inflammatory bowel disease (IBD) frequently affects younger patients and poses various challenges concerning pregnancy and childbirth. Maintaining good disease control throughout pregnancy is crucial, but expectant and pregnant patients may worry about the fetal impact of medications, leading to treatment discontinuation due to uncertainty about this issue. This study investigated the real-world drug-prescribing practices for pregnant patients with IBD in Japan and their potential connection to major congenital malformations (MCMs). METHODS: Overall, 277 female IBD patients who gave birth between 2010 and 2019 were selected from the JMDC claims database. The prescribing patterns of IBD medications and MCMs in the patients' offspring were analyzed. RESULTS: Among pregnant IBD patients, 74.4% received at least one medication from 90 days before pregnancy to 90 days after delivery. Trends in medication prescriptions during pregnancy in 2010-2019 revealed consistent use of oral 5-ASA, variable use of topical medications, a decrease in systemic steroids, and an increase in biologics. The prevalence of MCMs in children born to IBD-affected mothers did not differ significantly between those who did and did not receive IBD medications (8.6% vs 6.8%). Although circulatory system MCMs were slightly more common in the IBD medication group (4.9% vs 1.4%), this difference was not significant. Logistic regression analysis did not reveal an association between MCM risk and first-trimester use of IBD medications, including corticosteroids and biologics. CONCLUSIONS: This study provides insights into medication patterns in pregnant IBD patients and suggests no increased risk of MCMs associated with first-trimester IBD medication use.

Patients with Down syndrome (DS) are at risk of multiorgan dysfunction; kidney and urological impairment are common. This is due to a likely increased risk of congenital kidney and urological malformations (odds ratio of 4.5 compared to the general population in one study), more frequent associated comorbidities at risk of kidney dysfunction (such as prematurity in 9-24% of children, intrauterine growth retardation or low birth weight in 20%, and congenital heart disease in 44%), and more frequent lower urinary tract dysfunction (reported in 27-77% of children with DS). If present, malformations and comorbidities at risk of kidney dysfunction warrant regular kidney monitoring in addition to their treatment. Serum creatinine in children with DS has been shown to be higher than in the general population and asymptomatic hyperuricemia is reported in 12-33% of children or young adults with DS. Moreover cryptorchidism and testicular cancer are also more common and should be detected by clinical examination. Thus, persons with DS at risk of presenting kidney and urological impairment should be identified by prenatal ultrasonography, comorbidities at risk of kidney sequelae considered, and during regular medical follow-up, clinically examined and questioned to diagnose testicular anomalies and lower urinary tract dysfunction. This is of importance as such kidney and urological impairments are associated with impaired quality of life and mental health, and risk of kidney failure.

INTRODUCTION: Maternal obesity, a health condition increasingly prevalent worldwide, has been suggested to be associated with a higher risk of birth defects in offspring, whereas evidence from population-based data from China was largely lacking. Additionally, the role of gestational diabetes in the association between maternal obesity and birth defects remains unclear. We aimed to investigate the association of maternal pre-pregnancy overweight or obesity with any and different types of birth defects in offspring and the interaction between pre-pregnancy overweight or obesity and gestational diabetes. MATERIAL AND METHODS: We conducted a population-based cohort study including 257 107 singletons born between 2015 and 2021 in Longgang District, Shenzhen, China, using data from the Shenzhen Maternal and Child Health Management System. Poisson regression was conducted to estimate the associations of maternal pre-pregnancy overweight or obesity, as well as the interaction between pre-pregnancy overweight or obesity and gestational diabetes, with the risk of birth defects. Models were adjusted for maternal age at delivery, educational level, type of household registration, and gravidity. RESULTS: Maternal pre-pregnancy overweight was associated with a higher risk of any birth defect (risk ratio [RR] 1.21, 95% confidence interval [CI] 1.12 to 1.31) as well as of congenital malformations of the circulatory system (RR 1.26, 95% CI 1.12 to 1.41), eye/ear/face/neck (RR 1.42, 95% CI 1.04 to 1.94), and musculoskeletal system (RR 1.21, 95% CI 1.01 to 1.44). Maternal pre-pregnancy obesity was associated with a higher risk of any birth defect (RR 1.38, 95% CI 1.18 to 1.63) and congenital malformations of the circulatory system (RR 1.61, 95% CI 1.30 to 1.98). Infants born to overweight or obese mothers with gestational diabetes had a higher risk of congenital malformations of the circulatory system than infants born to overweight or obese mothers without gestational diabetes. CONCLUSIONS: Maternal pre-pregnancy overweight or obesity was associated with a higher risk of birth defects, particularly congenital malformations of the circulatory system, in offspring. Gestational diabetes interacts additively with pre-pregnancy overweight or obesity on modifying the risk of congenital malformations of the circulatory system. The importance of improving weight management and assessment of glucose and metabolic functions was emphasized among women planning for pregnancy who are overweight or obese.

PURPOSE: The purpose of this report is to investigate the association of atretic cephalocele (AC) with sinus pericranii (SP) in order to improve the management of AC. METHODS: Pediatric patients with AC who underwent repair surgeries were retrospectively analyzed. Anomalies including SP were evaluated using computed tomography angiography and venography (CTA/V) as well as magnetic resonance imaging. RESULTS: Fourteen patients were identified, comprising of 5 males and 9 females. The AC was located interparietally in 8 cases and occipitally in 6 cases. Seven cases (50%) were found to be associated with SP, all of which did not involve major intracranial venous circulation. Five out of 8 parietal ACs (63%) were accompanied by SP, while 2 out of 6 occipital ACs (33%) exhibited SP. All of the SP associated with AC only contributed to a small portion of the venous outflow, and the repair surgeries were successfully performed without excessive bleeding. CONCLUSION: More than half of the ACs were associated with SP, with a higher prevalence in the parietal region compared to the occipital region. For the appropriate management of AC, preoperative investigation of SP using CT venography is considered important.

Acalvaria is a rare congenital malformation characterized by the absence of bones and related muscles in a section of the skull. The number of reported cases in the literature is quite low, and it is generally considered a fatal malformation. We present a case of a newborn diagnosed with acalvaria malformation along with a review of the literature, emphasizing the importance of distinguishing this rare condition from malformations such as anencephaly, exencephaly and acrania. INTRODUCTION: The clinical landscape of acalvaria is scarcely populated, with the malformation often signifying a dire prognosis. Despite the embryological origin and pathogenesis remaining largely enigmatic, it has critical implications for the prenatal and postnatal therapeutic strategies. We investigate a case coupled with a comprehensive literary review to present a clearer clinical portrait and advance the alertness about this lethal anomaly among healthcare providers. DISCUSSION: The rarity of acalvaria constrains the establishment of a definitive incidence rate or a standardized treatment protocol. Varied associations with other neurological and systemic anomalies pose a significant ambiguity regarding its etiopathogenesis. Differential diagnosis remains intricate, relying on nuanced ultrasonographic examinations and an informed interpretation of embryological developments. CONCLUSION: Through our report of an acalvaria-affected newborn undetectable in prenatal ultrasound, we highlight the implications of rarity - the obstacle in uniform diagnosis and the resultant therapeutic challenge. The discussion fosters a need for heightened awareness and consolidating case reports to nurture clinical consensus. Furthermore, it underscores the necessity for multifaceted research efforts towards understanding etiology and optimizing treatment modalities.

BACKGROUND: Myelocele is a rare form of open spina bifida. Surgical repair is recommended prenatally or in the first 48 h. In some cases, the repair may be delayed, and specific surgical factors need to be considered. METHOD: We give a brief overview of the surgical anatomy, followed by a description of the surgical repair of a thoracolumbar Myelocele in an 11-month-old child. CONCLUSION: Surgical repair of the Myelocele stabilizes the neurological status, prevents local and central nervous system infections. The understanding of Myelocele anatomy enables its removal while preserving as much healthy tissue as possible and restoring normal anatomy.

BACKGROUNDS: Cleft lip with or without cleft palate (CL/P) is the most common congenital craniofacial anomaly, including non-syndromic cleft lip with or without cleft palate and cleft palate only. Failure in the fusion of median and lateral nasal processes, the maxillary prominence, and soft tissues around the oral cavity can cause CL/P. Previously, the prevalence has been estimated to be 1 among every 1000 births in 2014 among American neonates and no other reports have been available since. Thus, this study aimed to calculate the prevalence and trend of isolated CL/P among American live births from 2016 to 2021 with its associated risk factors. METHODS AND MATERIALS: In this cross-sectional population-based retrospective study, we used live birth data provided by the National Center for Health Statistics (NCHS) from the Center for Disease Control and Prevention (CDC). We calculated the prevalence per 10,000 live births of isolated (non-syndromic) CL/P from 2016 to 2021. To examine risk factors for developing isolated CL/P, we used logistic regression modelling. RESULTS: The total prevalence per 10,000 births from 2016 to 2021 was 4.88 (4.79-4.97), for both sexes, and 5.96 (5.82-6.10) for males, and 3.75 (3.64-3.87) for females. The prevalence did not show any consistent linear decreasing or increasing pattern. We found significant association between increased odds of developing isolated CL/P among cases with 20 to 24 year-old mothers (OR = 1.07, 1.01-1.13, p = 0.013), mothers who smoked 11 to 20 cigarettes per day (OR = 1.46, 1.33-1.60, p < 0.001), mothers with extreme obesity (OR = 1.32, 1.21-1.43, p < 0.001), mothers with grade II obesity (OR = 1.32, 1.23-1.42, p < 0.001), mothers with pre-pregnancy hypertension (OR = 1.17, 1.04-1.31, p = 0.009), mothers with pre-pregnancy diabetes mellitus (OR = 1.96, 1.71-2.25, p < 0.001), and mothers who used assisted reproductive technology (OR = 1.40, 1.18-1.66, p < 0.001). CONCLUSIONS: Our findings suggest a minuscule increase, albeit insignificant, in the trend of CL/P prevalence from 2016 to 2021. Developing CL/P had greater odds among mothers with pre-pregnancy diabetes, smoking, obesity, and pre-pregnancy hypertension mothers along with mothers who used assisted reproductive technology. Isolated CL/P had the highest prevalence in non-Hispanic Whites, American Indian or Alaskan Native and Native Hawaiian and Other Pacific Islanders.

BACKGROUND: Folic acid (FA) supplementation is associated with a lower risk of the neural tube and heart defects and is recommended for women of childbearing age. Although there are detailed recommendations, differences in the initiation time and duration of FA supplementation remain poorly studied. METHODS: A multicentre prospective study of 17,713 women was conducted. The incidence of congenital malformations in women taking a recommended dosage (e.g. 0.4 or 0.8 mg/day) of FA was compared with that in women without supplementation. The predicted probability of malformations by the initiation time and duration of FA use was estimated to determine optimal options. RESULTS: Periconceptional FA supplementation was associated with a lower and insignificant risk of congenital malformations (1.59% vs. 2.37%; odds ratio [OR] 0.69; 95% confidence interval [CI]: 0.44-1.08), heart defects (3.8 vs. 8.0 per 1000 infants; OR, 0.47; 0.21-1.02), and neural tube defects (7.0 vs. 11.5 per 10,000 infants; OR, 0.64; 0.08-5.15). FA use after pregnancy provided greater protection against total malformations. Statistically significant associations were found in women who initiated FA supplementation in the first month of gestation (OR, 0.55; 95% CI: 0.33-0.91) and in those who supplemented for 1 to 2 months (OR, 0.59; 95% CI: 0.36-0.98). Similar results were found for heart defects. The optimal initiation time was 1.5 (optimal range: 1.1 to 1.9) months before pregnancy and a duration of 4.0 (3.7 to 4.4) months was reasonable to achieve the lowest risk of congenital malformations. Heart defect prevention required an earlier initiation (2.2 vs. 1.1 months before pregnancy) and a longer duration (4.7 vs. 3.7 months) than the prevention of other malformations. CONCLUSIONS: The timely initiation of FA supplementation for gestation was associated with a decreased risk of congenital malformations, which was mainly attributed to its protection against heart defects. The initiation of FA supplementation 1.5 months before conception with a duration of 4 months is the preferred option for congenital malformation prevention.

OBJECTIVE: To assess the associations between congenital abnormalities and pediatric malignancies and evaluate the potential underlying molecular basis by collecting information on pediatric patients with cancer and congenital abnormalities. STUDY DESIGN: Tumeur Et Développement is a national, prospective, and retrospective multicenter study recording data of children with cancer and congenital abnormalities. When feasible, blood and tumoral samples are collected for virtual biobanking. RESULTS: From June 2013 to December 2019, 679 associations between pediatric cancers and congenital abnormalities were recorded. The most represented cancers were central nervous system tumors (n = 139; 20%), leukemia and myelodysplastic syndromes (n = 123; 18.1%), and renal tumors (n = 101; 15%). Congenital abnormalities were not related to any known genetic disorder in 66.5% of cases. In this group, the most common anomaly was intellectual disability (22.3%), followed by musculoskeletal (14.2%) and genitourinary anomalies (12.4%). Intellectual disability was mostly associated with hematologic malignancies. Embryonic tumors (neuroblastoma, Wilms tumor, and rhabdomyosarcoma) were associated with consistent abnormalities, sometimes with a close anatomical neighborhood between the abnormality and the neoplasm. CONCLUSIONS: In the first Tumeur Et Développement analysis, 3 major themes have been identified: (1) germline mutations with or without known cancer predisposition, (2) postzygotic events responsible for genomic mosaicism, (3) coincidental associations. New pathways involved in cancer development need to be investigated to improve our understanding of childhood cancers.

STUDY QUESTION: Are genetic disorders and congenital malformations associated with premature ovarian insufficiency (POI)? SUMMARY ANSWER: A wide range of genetic disorder and congenital malformation diagnoses are associated with POI, especially early onset POI. WHAT IS KNOWN ALREADY: POI is known to be associated with some genetic disorders, such as Turner syndrome and Fragile X premutation. Multiple genetic syndromes, such as ataxia teleangiectasia and galactosemia, have also been associated with an increased risk of POI, and many of these genetic syndromes manifest with various congenital malformations. In previous studies, a genetic aetiology has been found for 7-15% of POI cases. STUDY DESIGN, SIZE, DURATION: This population-based study included 5011 women diagnosed with POI in 1988-2017. The data were collected from various national registries and covers women with POI nationwide. PARTICIPANTS/MATERIALS, SETTING, METHODS: We identified 5011 women diagnosed with POI from 1988 to 2017 from the drug reimbursement registry of the Social Insurance Institution of Finland. Women with surgical POI (bilateral oophorectomy for benign indications) were not included. We selected four population controls per woman with POI matched by month and year of birth and municipality of residence. Diagnostic codes for genetic disorders and congenital malformations (GD/CM) for the cases and controls were searched from the Hospital Discharge Register. Binary logistic regression was used to compare the odds for GD/CM among cases and controls. To minimize bias, for the statistical analyses, we excluded diagnoses which were reported <2 years prior to the index date. MAIN RESULTS AND THE ROLE OF CHANCE: Of the women with POI, 15.9% (n = 797) had at least one diagnostic code for GD or CM. The odds ratio (OR) for Turner syndrome was 275 (95% CI 68.1-1110), and for other sex chromosome abnormalities, it was 12.7 (95% CI 4.1-39.1). For autosomal single gene disorders, the OR was 16.5 (95% CI 6.2-43.7). Women with POI had a higher odds of having a GD/CM diagnosis in all categories. The OR for GD/CM diagnoses was highest among the youngest POI patients (10-14 years old, OR 24.1, 95% CI 15.1-38.2). The odds of having POI were higher the more GD or CM diagnoses a woman had. LIMITATIONS, REASONS FOR CAUTION: Some women with POI might not have sought help for their symptoms and therefore remain undiagnosed. Due to the register-based nature of our study, we did not have access to more specific genetic diagnoses than international classification of diseases offers. WIDER IMPLICATIONS OF THE FINDINGS: GD/CM diagnoses were strongly associated with POI, especially when POI was diagnosed at a young age. The risk of POI was highest in women with multiple GD/CM diagnoses. Early onset POI can be a sign of underlying genetic disorder or congenital anomaly, and this should serve as a reminder for clinicians to consider further examinations. To avoid unnecessary delay in the diagnosis of POI and starting relevant hormone replacement therapy treatment, clinicians should be aware of these associations.

OBJECTIVE: The present study was aimed at investigating the effects of anti-seizure medications (ASMs), patient demographic characteristics, and the seizure type and frequency on the development of congenital malformations (CMs) in the infants of pregnant women with epilepsy (PWWE). METHODS: PWWE followed up at the neurology outpatient clinic of 21 centers between 2014 and 2019 were included in this prospective study. The follow-up of PWWE was conducted using structured, general pregnant follow-up forms prepared by the Pregnancy and Epilepsy Study Committee. The newborns were examined by a neonatologist after delivery and at 1 and 3 months postpartum. RESULTS: Of the infants of 759 PWWE, 7.2% had CMs, with 5.6% having major CMs. Polytherapy, monotherapy, and no medications were received by 168 (22.1%), 548 (72.2 %), and 43 (5.7 %) patients, respectively. CMs were detected at an incidence of 2.3% in infants of PWWE who did not receive medication, 5.7% in infants of PWWE who received monotherapy, and 13.7% in infants of PWWE who received polytherapy. The risk of malformation was 2.31-fold (95% confidence interval (CI): 1.48-4.61, p < .001) higher in infants of PWWE who received polytherapy. Levetiracetam was the most frequently used seizure medication as monotherapy, with the highest incidence of CMs occurring with valproic acid (VPA) use (8.5%) and the lowest with lamotrigine use (2.1%). The incidence of CMs was 5% at a carbamazepine dose <700 mg, 10% at a carbamazepine dose ≥700 mg, 5.5% at a VPA dose <750 mg, and 14.8% at a VPA dose ≥750 mg. Thus the risk of malformation increased 2.33 times (p = .041) in infants of PWWE receiving high-dose ASMs. SIGNIFICANCE: Birth outcomes of PWWE receiving and not receiving ASMs were evaluated. The risk of CMs occurrence was higher, particularly in infants of PWWE using VPA and receiving polytherapy. The incidence of CMs was found to be lower in infants of PWWE receiving lamotrigine.

BACKGROUND AND PURPOSE: Data on disease-modifying therapy (DMT) exposure throughout pregnancy in patients with multiple sclerosis are scarce. In this analysis, we assessed pregnancy and fetal outcomes following maternal glatiramer acetate (GA) exposure in all three trimesters among cases reported between 1997 and 2020. METHODS: Pregnancy reports of maternal in utero exposure to 20 and 40 mg/mL GA in all three trimesters from 1997 to 2020 were eligible. Both prospective pregnancy data, reported prior to knowledge of pregnancy outcome, and retrospective data were included. The primary endpoint was major congenital malformations (MCMs) based on the European Surveillance of Congenital Anomalies and Twins (EUROCAT) classification. Additional endpoints included fetal death, preterm birth, and low birth weight. The MCM rate was compared to the EUROCAT background rate. RESULTS: A total of 618 GA-exposed pregnancies in all three trimesters resulted in 634 fetuses, including 14 twin pregnancies. One fetal death was reported. All 414 fetuses with data reported prior to knowledge of pregnancy outcome (prospective data) were live births and no fetal death was reported. Preterm birth was reported in 23/213 (10.8%) pregnancies with known gestational age. Low birth weight was reported in 13/203 (6.4%) infants with known birth weight. The prevalence of MCM in prospective live births ranged from 2.2% to 2.4%, which was similar to background rates (2.1%-3.0%). The frequency of these pregnancy and infant outcomes was comparable across GA doses. CONCLUSIONS: In utero exposure to 20 and 40 mg/mL GA in three trimesters of pregnancy does not appear to be related to adverse pregnancy or infant outcomes.

BACKGROUND: Vascular malformations (VMs) are rare disorders that can cause pain, coagulopathy, disfigurement, asymmetric growth, and disability. Families affected by complex VMs experience misdiagnosis, limited trustworthy information, delayed or inappropriate treatments, and persistent uncertainty. However, more research is needed to understand the communication experiences of these families during clinical encounters. PROCEDURE: We performed semi-structured interviews with 34 parents of children with VMs (18% men; 82% women; mean age = 41 years) and 25 young adults with VMs (8% men; 88% women; 4% nonbinary; mean age = 29) living in the United States, recruited through four patient advocacy groups. We performed thematic analysis to assess communication experiences, using a previously developed functional model of communication in pediatric oncology as an a priori framework. RESULTS: We identified evidence of eight communication functions previously identified in pediatric oncology: building relationships, exchanging information, enabling self-management, managing uncertainty, responding to emotions, making decisions, providing validation, and supporting hope. Uncertainty was pervasive through participants' experiences and seemed to influence the fulfillment of communication functions. Fewer participants seemed to highlight the role of clinicians in responding to emotions or supporting hope, compared to other communication functions. CONCLUSION: Interviews with parents and young adult patients with VMs provided evidence for eight functions of communication. While exchanging information and building relationships were described by nearly every respondent, supporting hope and responding to emotions were mentioned less frequently. Future studies should develop patient-reported communication measures to quantify the fulfillment of these functions and to identify areas of communication in need of intervention.

OBJECTIVE: Knowledge regarding the long-term psychological adjustment of parents to children with prenatal diagnosis of congenital malformation is scarce. The aim of this study is to examine traumatic stress trajectories, resilience, and relationship satisfaction among parents to children with prenatal diagnosis of a congenital malformation, and to compare this to a sample of non-affected parents. METHODS: A prospective longitudinal cohort study was conducted at a tertiary perinatal referral center. Ninety-three mothers and 80 fathers who received a diagnosis of fetal anomaly during obstetric ultrasound examination (study group), and 110 mothers and 98 fathers with normal ultrasound findings (comparison group), reported their traumatic stress at four timepoints during pregnancy (T1-T4), 6 weeks after birth (T5), and 10-12 years after birth (T6). Resilience and relationship satisfaction was reported at 10-12 years after birth. RESULTS: Parents to children with a congenital malformation experienced significantly elevated traumatic stress levels over time, compared with parents of children without congenital malformation. The difference between groups was largest acutely after diagnosis and remained significant 10-12 years after the birth of the child. Resilience and relationship satisfaction levels were similar in both groups. CONCLUSIONS: Despite experiencing high levels of traumatic stress over time, parents to children with a congenital malformation reported resilience and relationship satisfaction at similar levels to non-affected parents. This suggests that despite ongoing long-term distress, parents are still able to maintain positive psychological coping resources.

PURPOSE: Chronic diseases are notorious in the way that they interfere with many aspects of a child's development, and this holds true for children with Hirschsprung disease (HD). The present research aims to (1) determine whether the health-related quality of life (HRQoL) of HD children differs from healthy paediatric populations; and (2) explore the relationship between HD children's HRQoL and psychosocial outcomes of parents. METHODS: Using a cross-sectional survey study design, children's HRQoL was assessed using the Pediatric Quality of Life Inventory (PedsQL), while parental psychosocial outcomes were measured using the Patient-Reported Outcomes Measurement Information System (PROMIS) anxiety and depression short-forms, Family Management Measure (FaMM), and Parent Experience of Child Illness. Surveys were administered over telephone to parents of 48 Australian children treated for HD (87.5% male, median age 4.5 years) during the period May to November 2021. RESULTS: While postoperative HRQoL of HD children was comparable to that of healthy age-matched controls, psychosocial quality of life of HD children was significantly poorer (mean difference = 3.40, CI [0.05, 6.76]). All parental outcome measures were significantly correlated with the PedsQL (r = - 0.77-0.67, p < 0.05) in expected directions, with FaMM subscales (except parent mutuality) demonstrating the most variation (R2 = 0.41-0.59). Of note, 31.3% of parents reported moderate to severe symptoms of anxiety on the PROMIS. CONCLUSION: Despite overall positive results for children, parents reported elevated symptoms of anxiety. This study highlights the importance of long-term follow-up care for HD patients and their families.

INTRODUCTION: To investigate the performance of the second-trimester ultrasound scan regarding ultrasound-detectable congenital malformations in a Danish region. The study sample was population-based, with 6 months of postnatal follow-up. Hospital records and autopsy reports were reviewed in each case to validate the prenatal ultrasound diagnosis. MATERIAL AND METHODS: This population-based cohort study included all fetuses (n = 19.367) alive at the second-trimester scan in four hospitals in a Danish region. The final diagnosis of the malformations was based on hospital records during the 6-month postnatal follow-up. In case of termination or stillbirth, the result from the autopsy report was used to validate the prenatal ultrasound diagnosis. RESULTS: The detection rate of congenital malformations in the prenatal screening program was 69%, where 18% was detected on the first-trimester scan and 51% on the second-trimester scan. Another 8% was detected in the third trimester. Specificity was 99.9%. The positive predictive value of the screening program was 94.5%, and the negative predictive value was 99.5%. The overall prevalence of malformations was 16.8 per 1000 fetuses, most frequently in the heart and the urinary tract. CONCLUSIONS: This study shows that the national screening program for congenital malformations can detect many severe malformations and is an effective screening test for malformations.
