Beta-Blocker Use in Pregnancy and Risk of Specific Congenital Anomalies: A European Case-Malformed Control Study.

The prevalence of chronic hypertension is increasing in pregnant women. Beta-blockers are among the most prevalent anti-hypertensive agents used in early pregnancy. The objective of this study was to investigate whether first-trimester use of beta-blockers increases the risk of specific congenital anomalies in offspring. A population-based case-malformed control study was conducted in 117,122 registrations of congenital anomalies from 17 European Concerted Action on Congenital Anomalies and Twins (EUROCAT) registries participating in EUROmediCAT with data for all or part of the period between 1995 and 2013. Associations previously reported in the literature (signals) were tested and an exploratory analysis was performed to identify new signals. Odds ratios of exposure to any beta-blocker or to a beta-blocker subgroup were calculated for each signal anomaly compared with two control groups (non-chromosomal, non-signal anomalies and chromosomal anomalies). The exploratory analyses were performed for each non-signal anomaly compared with all the other non-signal anomalies. The signals from the literature (congenital heart defects, oral clefts, neural tube defects and hypospadias) were not confirmed. Our exploratory analysis revealed that multi-cystic renal dysplasia had significantly increased odds of occurring after maternal exposure to combined alpha- and beta-blockers (adjusted odds ratio 3.8; 95% confidence interval 1.3-11.0). Beta-blocker use in the first trimester of pregnancy was not found to be associated with a higher risk of specific congenital anomalies in the offspring, but a new signal between alpha- and beta-blockers and multi-cystic renal dysplasia was found. Future large epidemiological studies are needed to confirm or refute our findings

Selective serotonin reuptake inhibitor prescribing before, during and after pregnancy:a population-based study in six European regions

Objective To explore the prescribing patterns of selective serotonin reuptake inhibitors (SSRIs) before, during and after pregnancy in six European population-based databases. Design Descriptive drug utilisation study. Setting Six electronic healthcare databases in Denmark, the Netherlands, Italy (Emilia Romagna/Tuscany), Wales and the rest of the UK. Population All women with a pregnancy ending in a live or stillbirth starting and ending between 2004 and 2010. Methods A common protocol was implemented across databases to identify SSRI prescriptions issued (UK) or dispensed (non-UK) in the year before, during or in the year following pregnancy. Main outcome measures The percentage of deliveries in which the woman received an SSRI prescription in the year before, during or in the year following pregnancy. We also compared the choice of SSRIs and changes in prescribing over the study period. Results In total, 721 632 women and 862 943 deliveries were identified. In the year preceding pregnancy, the prevalence of SSRI prescribing was highest in Wales [9.6%; 95% confidence interval (CI95), 9.4-9.8%] and lowest in Emilia Romagna (3.3%; CI95, 3.2-3.4%). During pregnancy, SSRI prescribing had dropped to between 1.2% (CI95, 1.1-1.3%) in Emilia Romagna and 4.5% (CI95, 4.3-4.6%) in Wales. The higher UK pre-pregnancy prescribing rates resulted in higher first trimester exposures. After pregnancy, SSRI prescribing increased most rapidly in the UK. Paroxetine was more commonly prescribed in the Netherlands and Italian regions than in Denmark and the UK. Conclusions The higher SSRI prescribing rates in the UK, compared with other European regions, raise questions about differences in the prevalence and severity of depression and its management in pregnancy across Europe.

Comorbidity and survival of Danish breast cancer patients from 1995 to 2005

Comorbid diseases can affect breast cancer prognosis. We conducted a population-based study of Danish women diagnosed with a first primary breast cancer from 1995 to 2005 (n=9300), using hospital discharge registry data to quantify comorbidities by Charlson score. We examined the influence of comorbidities on survival, and quantified their impact on relative mortality rates. The prevalence of patients with a Charlson score=‘0' fell from 86 to 81%, with an increase in those with Charlson score=‘1–2' from 13 to 16%, and score=‘3+' from 1 to 2%. One- and five-year survival for patients with Charlson score=‘0' and ‘1–2' was better for those diagnosed in 1998–2000 than in 1995–1997. Overall, patients diagnosed in 2001–2004 (mortality ratio (MR)=0.80, 95% CI=0.68–0.95) and 1998–2000 (MR=0.92, 95% CI=0.78–1.09) had lower 1-year age-adjusted mortality compared to those diagnosed in 1995–1997 (reference period). Patients with Charlson scores ‘1–2' and ‘3+' had higher age-adjusted 1-year mortality than those with a Charlson score=‘0' in each time period (2001–2004: MR‘1–2'=1.76, 95% CI=1.35–2.30, and MR‘3+'=3.78, 95% CI=2.51–5.68; and 1998–2000: MR‘1–2'=1.60, 95% CI=1.36–1.88 and MR‘3+'=2.34, 95% CI=1.65–3.33). Similar findings were observed for 5-year age-adjusted mortality. Additional analyses, adjusted for stage, indicated that confounding by stage could not explain these findings. Despite continued improvements in breast cancer survival, we found a trend of poorer survival among breast cancer patients with severe comorbidities even after adjusting for age and stage. Such poorer survival is an important public health concern and can be expected to worsen as the population ages

The Healthcare Needs of Children With Down Syndrome in the First Year of Life: An Analysis of the EUROlinkCAT Data Linkage Study

\ua9 2025 The Author(s). Paediatric and Perinatal Epidemiology published by John Wiley & Sons Ltd.Background: Globally, Down syndrome is the most common chromosomal anomaly, often co-occurring with cardiac or gastrointestinal anomalies. There is a lack of robust data on specific healthcare needs of children with Down syndrome compared to children with other major congenital anomalies. Objectives: To quantify the healthcare needs of children with Down syndrome in the first year of life compared to children with major congenital anomalies in a large population-based cohort across Europe. Methods: The EUROlinkCAT study was a multicentre data linkage study between congenital anomaly registries in Europe and hospital and mortality databases. Children born between 1st January 1997 and 31st December 2014 were included. Summary statistics were used to compare differences between children (those with Down syndrome compared to all major anomalies) and regions. Random-effects meta-analysis was used to pool results related to survival, need for intensive care and ventilation support. Results: A total of 3554 children were born with Down syndrome out of 89,081 children with major congenital anomalies. The pooled 1-year survival was 95.4%. In every region, > 80% of children with Down syndrome had a hospital admission excluding the birth admission. Hospital length of stay in the first year was higher for children with Down syndrome compared to those with all anomalies (median: 14 versus 7 days). Despite having similar need for ventilation support (9.7% vs. 8.4%), children with Down syndrome had higher rates of intensive care admission than all children with anomalies (24.8% vs. 13.0%). Conclusions: There is a high need for hospital care for children born with Down syndrome in the first year of life. Future work should continue to explore the long-term prognosis for children with Down syndrome to ensure their care needs are met

Atrioventricular septal defects among infants in Europe: a population-based study of prevalence, associated anomalies, and survival.

OBJECTIVE: To describe the epidemiology of chromosomal and non-chromosomal cases of atrioventricular septal defects in Europe. METHODS: Data were obtained from EUROCAT, a European network of population-based registries collecting data on congenital anomalies. Data from 13 registries for the period 2000-2008 were included. RESULTS: There was a total of 993 cases of atrioventricular septal defects, with a total prevalence of 5.3 per 10,000 births (95% confidence interval 4.1 to 6.5). Of the total cases, 250 were isolated cardiac lesions, 583 were chromosomal cases, 79 had multiple anomalies, 58 had heterotaxia sequence, and 23 had a monogenic syndrome. The total prevalence of chromosomal cases was 3.1 per 10,000 (95% confidence interval 1.9 to 4.3), with a large variation between registers. Of the 993 cases, 639 cases were live births, 45 were stillbirths, and 309 were terminations of pregnancy owing to foetal anomaly. Among the groups, additional associated cardiac anomalies were most frequent in heterotaxia cases (38%) and least frequent in chromosomal cases (8%). Coarctation of the aorta was the most common associated cardiac defect. The 1-week survival rate for live births was 94%. CONCLUSION: Of all cases, three-quarters were associated with other anomalies, both chromosomal and non-chromosomal. For infants with atrioventricular septal defects and no chromosomal anomalies, cardiac defects were often more complex compared with infants with atrioventricular septal defects and a chromosomal anomaly. Clinical outcomes for atrioventricular septal defects varied between regions. The proportion of termination of pregnancy for foetal anomaly was higher for cases with multiple anomalies, chromosomal anomalies, and heterotaxia sequence

Global birth defects app: An innovative tool for describing and coding congenital anomalies at birth in low resource settings

BACKGROUND: Surveillance programs in low- and middle-income countries (LMICs) have difficulty in obtaining accurate information about congenital anomalies. METHODS: As part of the ZikaPLAN project, an International Committee developed an app for the description and coding of congenital anomalies that are externally visible at birth, for use in low resource settings. The “basic” version of the app was designed for a basic clinical setting and to overcome language and terminology barriers by providing diagrams and photos, sourced mainly from international Birth Defects Atlases. The “surveillance” version additionally allows recording of limited pseudonymized data relevant to diagnosis, which can be uploaded to a secure server, and downloaded by the surveillance program data center. RESULTS: The app contains 98 (88 major and 10 minor) externally visible anomalies and 12 syndromes (including congenital Zika syndrome), with definitions and International Classification of Disease v10 -based code. It also contains newborn examination videos and links to further resources. The user taps a region of the body, then selects among a range of images to choose the congenital anomaly that best resembles what they observe, with guidance regarding similar congenital anomalies. The “basic” version of the app has been reviewed by experts and made available on the Apple and Google Play stores. Since its launch in November 2019, it has been downloaded in 39 countries. The "surveillance” version is currently being field-tested. CONCLUSION: The global birth defects app is a mHealth tool that can help in developing congenital anomaly surveillance in low resource settings to support prevention and care

Surveillance of multiple congenital anomalies; searching for new associations

\ua9 2023, The Author(s).Many human teratogens are associated with a spectrum of congenital anomalies rather than a single defect, and therefore the identification of congenital anomalies occurring together more frequently than expected may improve the detection of teratogens. Thirty-two EUROCAT congenital anomaly registries covering 6,599,765 births provided 123,566 cases with one or more major congenital anomalies (excluding chromosomal and genetic syndromes) for the birth years 2008–2016. The EUROCAT multiple congenital anomaly algorithm identified 8804 cases with two or more major congenital anomalies in different organ systems, that were not recognized as part of a syndrome or sequence. For each pair of anomalies, the odds of a case having both anomalies relative to having only one anomaly was calculated and the p value was estimated using a two-sided Fisher’s exact test. The Benjamini–Hochberg procedure adjusted p values to control the false discovery rate and pairs of anomalies with adjusted p values &lt; 0.05 were identified. A total of 1386 combinations of two anomalies were analyzed. Out of the 31 statistically significant positive associations identified, 20 were found to be known associations or sequences already described in the literature and 11 were considered “potential new associations” by the EUROCAT Coding and Classification Committee. After a review of the literature and a detailed examination of the individual cases with the anomaly pairs, six pairs remained classified as new associations. In summary, systematically searching for congenital anomalies occurring together more frequently than expected using the EUROCAT database is worthwhile and has identified six new associations that merit further investigation
