Disease severity impacts perceived quality of life in congenital diaphragmatic hernia: a prospective observational study.

BACKGROUND: While research indicates comparable quality of life (QOL) in congenital diaphragmatic hernia (CDH) and healthy populations, the effect of CDH severity on patients' health perceptions remains unexplored. We aimed to assess QOL perception in CDH, hypothesising a decline correlated with increased disease severity. METHODS: In this prospective observational study, we analysed patients with CDH aged 5 years and above participating in a longitudinal outpatient programme. We excluded bilateral CDH, genetic/syndromic conditions, prematurity and late diagnosis. Participants self-administered the age-adapted Pediatric Quality of Life Inventory (PedsQL) survey, covering four domains (physical, emotional, social, school). After enrolment, data were collected blind to severity status (larger defects denoting significant/'severe' disease). Repeated measurements were managed using a random mixed-effects model. RESULTS: Of 34 participants (50% males) who completed the PedsQL, 10 provided measurements at two visits. Eight required a patch (type C), while 26 had primary repairs (type A=8; type B=18). Age at first evaluation was comparable across groups (no patch: median 11 (7-16), patch: 13 (8-15) years, p=0.78). Severe CDH correlated significantly with lower PedsQL scores (adjusted ß: -18%, 95% CI -28%; -7%, adjusted for age at visit and sex). Lower scores specifically occurred in walking, exercising, social and academic functioning. CONCLUSION: Severe CDH significantly lowers QOL. This finding is crucial for resource allocation in long-term CDH health surveillance and advocates for regular inclusion of patient experiences in quality improvement efforts.

Gestational Age-Specific Markers Associated with Postnatal Intervention in Fetal Suspicion of Coarctation of the Aorta.

OBJECTIVE: Fetal diagnosis of coarctation of the aorta (CoA) is currently associated with a high false-positive rate. Many predictive markers may be gestational age (GA)-specific. We sought to establish GA-specific traditional and speckle-tracking fetal echocardiography (STE) markers predictive of true CoA in neonates with prenatal suspicion. STUDY DESIGN: This is a retrospective case-control study. We compared the fetal ventricular and arch dimensions, as well as the deformation parameters by STE, of infants who required a postnatal intervention for their CoA with those who did not. Cohort was stratified based on GA before or after 30 weeks. Data extractors were masked to the outcome. The first fetal echocardiogram available was used. RESULTS: Seventy-five newborns with a fetal echocardiography performed between October 2013 and May 2022 for an antenatal suspicion of CoA were included, of which 59 (79%) had an aortic arch with nonsignificant obstruction upon ductal closure, and 16 (21%) underwent a neonatal intervention for a confirmed CoA. Before 30 weeks' GA, the right ventricular to left ventricular (RV/LV) end-diastolic width and end-diastolic area (EDA) ratios were most associated with postnatal CoA confirmation (area under the curve [AUCs] = 0.96 and 0.92). After 30 weeks' GA, the RV/LV end-diastolic width ratio (AUC = 0.95), the Z-score for the ascending aorta (AUC = 0.93), and the LV end-diastolic width Z-score (AUC = 0.91) performed the best. A decreased RV peak longitudinal strain was observed in those who developed true CoA and performed well by receiver operating characteristic analysis after 30 weeks (AUC = 0.85). In the overall cohort, the RV/LV EDA ratio was the most sensitive predictor of CoA and identified all cases with CoA. Indeed, a cutoff > 1.24 had a specificity of 69.5% and a sensitivity of 100% (receiver operating characteristic curve with an AUC of 0.88). CONCLUSION: We outlined sensitive and specific fetal markers associated with postnatal CoA based on GA at suspicion. KEY POINTS: · Fetal ventricular disproportion predicts postnatal coarctation.. · A decreased right ventircular contraction was observed in those with coarctation.. · Fetal markers differ based on gestational age at fetal evaluation..

Congenital Diaphragmatic Hernia: Pulmonary Hypertension and Pulmonary Vascular Disease.

This review provides a comprehensive summary of the current understanding of pulmonary hypertension (PH) in congenital diaphragmatic hernia, outlining the underlying pathophysiologic mechanisms, methods for assessing PH severity, optimal management strategies, and prognostic implications.

Early cardiac function and death, severe bronchopulmonary dysplasia and pulmonary hypertension in extremely preterm infants.

BACKGROUND: Association between early cardiac function and neonatal outcomes are scarcely reported. The aim of the current study was to describe this association with death, severe bronchopulmonary dysplasia (BPD) and BPD-related pulmonary hypertension (PH). METHODS: Retrospective cohort study of infants <29 weeks born between 2015 and 2019. Infants with clinically acquired echocardiography at ≤21 days after birth were included and data were extracted by an expert masked to outcomes. RESULTS: A total of 176 infants were included. Echocardiogram was performed at a median of 9 days (IQR 5-13.5). Of these, 31 (18%) had death/severe BPD and 59 (33.5%) had death/BPD-related PH. Infants with death/severe BPD were of lower birth weight (745 [227] vs 852 [211] grams, p = 0.01) and more exposed to invasive ventilation, late-onset sepsis, inotropes and/or postnatal steroids. Early echocardiograms demonstrated decreased right ventricular [Tricuspid Annular Plane Systolic Excursion: 5.2 (1.4) vs 6.2 (1.5) cm, p = 0.03] and left ventricular function [Ejection fraction 53 (14) vs 58 (10) %, p = 0.03]. Infants with death/BPD-related PH had an increased Eccentricity index (1.35 [0.20] vs 1.26 [0.19], p = 0.02), and flat/bowing septum (19/54 [35%] vs 20/109 [18%], p = 0.021). CONCLUSIONS: In extremely premature infants, altered ventricular function and increased pulmonary pressure indices within the first 21 days after birth, were associated with the combined outcome of death/severe BPD and death/BPD-related PH. IMPACT: Decreased cardiac function on echocardiography performed during first three weeks of life is associated with severe bronchopulmonary dysplasia in extremely premature infants. In extreme preterm infants, echocardiographic signs of pulmonary hypertension in early life are associated with later BPD-related pulmonary hypertension close to 36 weeks post-menstrual age. Early cardiac markers should be further studied as potential intervention targets in this population. Our study is adding comprehensive analysis of echocardiographic data in infants born below 29 weeks gestational age.

Pulmonary Hypertension and Necrotizing Enterocolitis in Neonates Treated with Diazoxide.

OBJECTIVE: This study aimed to evaluate the prevalence of adverse outcomes, specifically pulmonary hypertension (PH) and suspected or confirmed necrotizing enterocolitis (NEC), and their associated risk factors, in neonates treated with diazoxide. STUDY DESIGN: A retrospective study in infants born ≥ 316/7 weeks and admitted between January 2014 and June 2020. Combined adverse outcomes possibly associated to diazoxide were PH (systolic pulmonary pressure of ≥40 mm Hg or an eccentricity index ≥1.3) and suspected or confirmed NEC (suspected: stop feeds and antibiotics and confirmed: modified Bell stage ≥2). Echocardiography data extractors were masked to infants' characteristics. RESULTS: A total of 63 infants were included; 7 (11%) with suspected and 1 (2%) with confirmed NEC. Of the 36 infants with an available echocardiography after initiation of diazoxide treatment, 12 (33%) had PH. All infants with suspected or confirmed NEC were males (p = 0.01), whereas PH occurred mostly in females (75%, p = 0.02). The combined adverse outcome occurred in 14/26 (54%) infants exposed to >10 mg/kg/day, compared to 6/37 (16%) exposed to ≤10 mg/kg/day (p = 0.006). This association remained significant after adjustment for sex, small for gestational age status, and gestational age at birth (odds ratio: 6.1, 95% confidence interval: 1.7-21.7, p = 0.005). Left ventricular dysfunction was found in 19 infants (30%) but was not discriminative for the combined outcome. CONCLUSION: PH and suspected or confirmed NEC were identified frequently in neonates treated with diazoxide. A total dose >10 mg/kg/day was associated with an increased occurrence of these complications. KEY POINTS: · PH and suspected or confirmed NEC were frequently found in neonates treated with diazoxide.. · A total dose >10 mg/kg/day was associated with an increased occurrence of these complications.. · Echocardiography screening should be considered in neonates exposed to diazoxide..

Guidelines for urinary tract infections and antenatal hydronephrosis should be gender specific.

AIM: Febrile urinary tract infections (UTIs) may be associated with long-term renal damage. Our goal was to identify risk factors for future UTIs in children who had voiding cystourethrography (VCUG) as a part of an antenatal hydronephrosis (ANH) assessment or after a febrile UTI. METHODS: We conducted a cohort study based on the medical records of children aged 0-24 months who underwent a VCUG between January 2004 and December 2011 and had at least six months of follow-up. The incidence of future UTIs was assessed. RESULTS: We included 285 children: 176 had a primary UTI and 109 had ANH. We recorded 28 UTIs during the follow-up period, and the risk was 12.5% after a primary UTI and 5.5% after an ANH (p = 0.049). Multivariate analysis showed no risk difference was found between the groups. Females had a greater risk of febrile UTIs (hazard ratio 3.3, 95% confidence interval 1.03-9.2, p = 0.04), but the UTI risk did not differ between children with or without VURs. CONCLUSION: Female infants were at greater risk of febrile UTIs, regardless of the presence of VUR, VUR degree, ANH or a previous UTI. Clinical guidelines for UTI and ANH assessment should preferably be gender specific.
