RESUMO

BACKGROUND: Obstetrical complications impact the health of mothers and offspring along the life course, resulting in an increased burden of chronic diseases. One specific complication is abruption, a life-threatening condition with consequences for cardiovascular health that remains poorly studied. OBJECTIVES: To describe the design and data linkage algorithms for the Placental Abruption and Cardiovascular Event Risk (PACER) cohort. POPULATION: All subjects who delivered in New Jersey, USA, between 1993 and 2020. DESIGN: Retrospective, population-based, birth cohort study. METHODS: We linked the vital records data of foetal deaths and live births to delivery and all subsequent hospitalisations along the life course for birthing persons and newborns. The linkage was based on a probabilistic record-matching algorithm. PRELIMINARY RESULTS: Over the 28 years of follow-up, we identified 1,877,824 birthing persons with 3,093,241 deliveries (1.1%, n = 33,058 abruption prevalence). The linkage rates for live births-hospitalisations and foetal deaths-hospitalisations were 92.4% (n = 2,842,012) and 70.7% (n = 13,796), respectively, for the maternal cohort. The corresponding linkage rate for the live births-hospitalisations for the offspring cohort was 70.3% (n = 2,160,736). The median (interquartile range) follow-up for the maternal and offspring cohorts was 15.4 (8.1, 22.4) and 14.4 (7.4, 21.0) years, respectively. We will undertake multiple imputations for missing data and develop inverse probability weights to account for selection bias owing to unlinked records. CONCLUSIONS: Pregnancy offers a unique window to study chronic diseases along the life course and efforts to identify the aetiology of abruption may provide important insights into the causes of future CVD. This project presents an unprecedented opportunity to understand how abruption may predispose women and their offspring to develop CVD complications and chronic conditions later in life.

RESUMO

The use of expanded carrier screening (ECS) to assess reproductive risk for autosomal recessive (AR) or X-linked recessive (XLR) conditions has been increasingly integrated into obstetrical care. The aim of this study was to determine what proportion of pediatric patients seen by a medical genetics practice could have had their diagnosis predicted if the parent(s) had undergone currently available ECS at the time of data collection in 2021. A retrospective chart review of patients seen for a medical genetic evaluation at a large academic institution was performed from June 1, 2017, through June 1, 2020. At this institution, 8% of patients were diagnosed with an AR or XLR condition. Of these patients, 61% of the diagnoses could have been predicted in advance if the parent(s) had undergone ECS via the panel referenced in this study. The results of this study highlight the broad range of conditions currently seen in a clinical setting that could be identified as a risk prior to or during pregnancy via ECS. In the prenatal setting, ascertainment of reproductive risk via ECS enables prospective parents to undertake interventions such as prenatal and preimplantation genetic diagnosis. For parents who decline reproductive risk-reducing measures, knowledge about neonatal risk allows for prompt confirmatory testing. In the pediatric setting, the option of early and focused testing can benefit affected individuals and their families.

RESUMO

OBJECTIVES: To ascertain the rate of unexpected findings on carrier screening (CS) and assess whether implications are disclosed to patients. METHODS: We performed a retrospective observational study of subjects who had CS after pre-test counseling from a licensed genetic counselor at a large tertiary care center. We quantified the rate of unexpected finding on CS, defined as manifesting carriers (MCs), genotypes predicting phenotype, and chromosome abnormalities. We determined how often patients were informed of implications. We performed subgroup analyses by type of unexpected finding and calculated odds ratios (OR) and 95% confidence intervals (CI) for carrier testing methodology (genotype) and number of genes tested. RESULTS: A total of 4685 patients had CS over the selected time frame. Of those patients, 412 patients (8.8%) had one unexpected finding and 29 patients (0.6%) had two or more findings. In total, 466 unexpected findings were identified, including 437 MC conditions, 23 genotypes predicting phenotype, and 6 chromosome abnormalities. Patients were informed of the implications for MCs, genotypes predicting phenotype, and chromosome abnormalities in 27.6%, 91.3%, and 100% of cases, respectively. More unexpected findings were detected with sequencing compared to genotyping (OR 2.21 and 95% CI 1.76-2.76) and with ≥200 gene panels compared to <200 gene panels (OR 1.79 and 95% CI 1.47-2.17). CONCLUSION: This study highlights that nondisclosure of unexpected findings on CS is common and underscores the need for further research to improve post-test counseling and follow-up.
