Impact of the COVID-19 Pandemic on Health-Related Concerns, Quality of Lifeand Psychological Adjustment in Young Adults with Congenital Heart Disease

Background: The risk for a severe disease course in case of infection with SARS-CoV-2 in young adults with congenital heart disease is largely unknown, potentially leading to uncertainty and anxiety among affected patients. This study aims to investigate health-related concerns, health-related quality of life and psychological adjustment in patients with congenital heart disease compared to healthy peers during the COVID-19 pandemic. Methods: One-hundred patients with congenital heart disease and 50 controls (M = 29.7, SD = 3.8 years) were recruited. They completed an online survey including the assessment of health-related concerns regarding COVID-19, the 12-item Short Form Health Survey and the Brief Symptom Inventory. Results: Patients considered COVID-19 to be a more serious issue (Generalized odds ratio [GenOR] = 1.67, p = 0.04), were more concerned about becoming infected (GenOR = 2.93, p < 0.001) and expressed more fear about leaving their homes (GenOR = 1.81, p = 0.004) while general anxiety symptoms were not different between groups (p = 0.23). Patients relied more on family and friends for support (30% vs. 2% in controls, p < 0.001) and reported better compliance with protective measures (p = 0.03). Mental health-related quality of life and psychological adjustment were not different between groups (p = 0.17 and p = 0.68, respectively). Physical health-related quality of life was lower in patients compared to controls (p = 0.03). Conclusions: Young adults with congenital heart disease in Switzerland are more concerned about their health during the COVID-19 pandemic compared to healthy peers. These concerns, however, do not translate into generally impaired mental wellbeing. The impact of the easing of lockdown measures on long-term anxiety levels and quality of life requires further stud

Perioperative Course and Socioeconomic Status Predict Long-Term Neurodevelopment Better Than Perioperative Conventional Neuroimaging in Children with Congenital Heart Disease.

The objective of the study was to compare the use of neonatal conventional brain magnetic resonance imaging (MRI) with that of clinical factors and socioeconomic status (SES) to predict long-term neurodevelopment in children with severe congenital heart disease (CHD). In this prospective cohort study, perioperative MRIs were acquired in 57 term-born infants with CHD undergoing cardiopulmonary bypass surgery during their first year of life. Total brain volume (TBV) was measured using an automated method. Brain injury severity (BIS) was assessed by an established scoring system. The neurodevelopmental outcome was assessed at 6 years using standardized test batteries. A multiple linear regression model was used for cognitive and motor outcomes with postoperative TBV, perioperative BIS, CHD complexity, length of hospital stay, and SES as covariates. CHD diagnoses included univentricular heart defect (n = 15), transposition of the great arteries (n = 33), and acyanotic CHD (n = 9). Perioperative moderate-to-severe brain injury was detected in 15 (26%) patients. The total IQ was similar to test norms (P = .11), whereas the total motor score (P &lt; .001) was lower. Neither postoperative TBV nor perioperative BIS predicted the total IQ, but SES (P &lt; .001) and longer hospital stay (P = .004) did. No factor predicted the motor outcome. Although the predictive value of neonatal conventional MRIs for long-term neurodevelopment is low, duration of hospital stay and SES better predict the outcome in this CHD sample. These findings should be considered in initiating early therapeutic support

Mental health-related quality of life in mothers of children with surgically repaired congenital heart disease: a 13-year longitudinal study

Aims: Having a child with congenital heart disease (CHD) can affect parental health-related quality of life (HR-QoL). We investigated the long-term trajectories of mental HRQoL (m-HRQoL) in mothers of children with CHD and examined risk factors for persistent low m-HRQoL. Methods: One hundred twenty-five mothers of children with CHD completed a standardized questionnaire on m-HRQoL (mental subscale SF-12) after the children’s first open-heart surgery and subsequently when the children were 1, 4, 6, 10, and 13 years old. A z-score for m-HRQoL was calculated with national norms. Latent class growth analysis (LCGA) was used to identify subgroups of mothers with regards to their m-HRQoL trajectories over time. Regression analysis investigated predictors for chronically low m-HRQoL. Results: Compared to norms, mothers of children with CHD had significantly lower m-HRQoL immediately after open-heart surgery (β = −0.30 (CI-95: −0.44, −0.15)). Subsequently, m-HRQoL increased to a normal level (m-HRQoL compared to the norm from 1 to 13 years: β ranges between 0.05 and 0.27). LCGA revealed two distinct groups of m-HRQoL trajectories: A group with normal m-HRQoL (75% of mothers, means z-scores range between − 0.76 and 0.62) and a group with chronically low m-HRQoL (25% of mothers, mean z-scores range between −1.32 and −0.10). Chronically, low m-HRQoL was associated with poorer social support (OR = 3.39 (CI-95: 1.40, 8.49), p = 0.008) but not with parental education, migration background, number of open-heart surgeries, diagnosis of a univentricular CHD, or low IQ. Conclusion: A quarter of mothers of children with CHD have chronically low m-HRQoL throughout their child’s development, especially those mothers with poor social support. Further studies of family-oriented approaches are needed to identify and support these mothers and reinforce parental well-being

Hyperekplexia Phenotype of Glycine Receptor α1 Subunit Mutant Mice Identifies Zn2+ as an Essential Endogenous Modulator of Glycinergic Neurotransmission

SummaryZn2+ is thought to modulate neurotransmission by affecting currents mediated by ligand-gated ion channels and transmitter reuptake by Na+-dependent transporter systems. Here, we examined the in vivo relevance of Zn2+ neuromodulation by producing knockin mice carrying the mutation D80A in the glycine receptor (GlyR) α1 subunit gene (Glra1). This substitution selectively eliminates the potentiating effect of Zn2+ on GlyR currents. Mice homozygous for Glra1(D80A) develop a severe neuromotor phenotype postnatally that resembles forms of human hyperekplexia (startle disease) caused by mutations in GlyR genes. In spinal neurons and brainstem slices from Glra1(D80A) mice, GlyR expression, synaptic localization, and basal glycinergic transmission were normal; however, potentiation of spontaneous glycinergic currents by Zn2+ was significantly impaired. Thus, the hyperekplexia phenotype of Glra1(D80A) mice is due to the loss of Zn2+ potentiation of α1 subunit containing GlyRs, indicating that synaptic Zn2+ is essential for proper in vivo functioning of glycinergic neurotransmission

Is maternal trait anxiety a risk factor for late preterm and early term deliveries?

BACKGROUND Anxiety is associated with preterm deliveries in general (before week 37 of pregnancy), but is that also true for late preterm (weeks 34/0-36/6) and early term deliveries (weeks 37/0-38/6)? We aim to examine this association separately for spontaneous and provider-initiated deliveries. METHODS Participants were pregnant women from the Norwegian Mother and Child Cohort Study (MoBa), which has been following 95 200 pregnant women since 1999. After excluding pregnancies with serious health complications, 81 244 participants remained. National ultrasound records were used to delineate late preterm, early term, and full-term deliveries, which then were subdivided into spontaneous and provider-initiated deliveries. We measured trait anxiety based on two ratings of the anxiety items on the Symptom Checklist-8 (Acta Psychiatr Scand 87:364-7, 1993). Trait anxiety was transformed into categorizing the score at the mean and at ± 2 standard deviations. RESULTS Trait anxiety was substantially associated with late preterm and early term deliveries after adjusting for confounders. In the whole sample, women with the highest anxiety scores (+2 standard deviations) were more likely [(odds ratio (OR) = 1.7; 95 % confidence-interval (CI) 1.3-2.0)] to delivering late preterm than women with the lowest anxiety scores. Their odds of delivering early term were also high (OR = 1.4; CI 1.3-1.6). Women with spontaneous deliveries and the highest anxiety scores had higher odds (OR = 1.4; CI 1.1-1.8) of delivering late preterm and early term (OR = 1.3; CI = 1.3-1.5). The corresponding odds for women with provider-initiated deliveries were OR = 1.7 (CI = 1.2-2.4) for late preterm and OR = 1.3 for early term (CI = 1.01-1.6). Irrespective of delivery onset, women with provider-initiated deliveries had higher levels of anxiety than women delivering spontaneously. However, women with high anxiety were equally likely to have provider-initiated or spontaneous deliveries. CONCLUSIONS This study is the first to show substantial associations between high levels of trait anxiety and late preterm delivery. Increased attention should be given to the mechanism underlying this association, including factors preceding the pregnancy. In addition, acute treatment should be offered to women displaying high levels of anxiety throughout pregnancy to avoid suffering for the mother and the child

A model for cyclotron resonance scattering features

(abbreviated version of the abstract) We study the physics of cyclotron line formation in the high-energy spectra of accreting X-ray pulsars using Monte Carlo methods, assuming that the line-forming region is a low-density electron plasma in a sub-critical magnetic field. We investigate the dependence of the shape of the fundamental line on angle, geometry, optical depth and temperature. We also discuss variations of the line ratios for non-uniform magnetic fields. These numerical predictions for the line profiles are linked to results from observational data analysis using an XSPEC model based on the Monte Carlo simulations. We apply this model to observational data from RXTE and INTEGRAL. The predicted strong emission wings of the fundamental cyclotron feature are not found in observational data, hinting at a bottom illuminated slab geometry for line formation.Comment: 16 pages, 15 figures, Astron.

White matter injury in term neonates with congenital heart diseases: Topology & comparison with preterm newborns

Background: Neonates with congenital heart disease (CHD) are at high risk of punctate white matter injury (WMI) and impaired brain development. We hypothesized that WMI in CHD neonates occurs in a characteristic distribution that shares topology with preterm WMI and that lower birth gestational age (GA) is associated with larger WMI volume. Objective: (1) To quantitatively assess the volume and location of WMI in CHD neonates across three centres. (2) To compare the volume and spatial distribution of WMI between term CHD neonates and preterm neonates using lesion mapping. Methods: In 216 term born CHD neonates from three prospective cohorts (mean birth GA: 39 weeks), WMI was identified in 86 neonates (UBC: 29; UCSF: 43; UCZ: 14) on pre- and/or post-operative T1 weighted MRI. WMI was manually segmented and volumes were calculated. A standard brain template was generated. Probabilistic WMI maps (total, pre- and post-operative) were developed in this common space. Using these maps, WMI in the term CHD neonates was compared with that in preterm neonates: 58 at early-in-life (mean postmenstrual age at scan 32.2 weeks); 41 at term-equivalent age (mean postmenstrual age at scan 40.1 weeks). Results: The total WMI volumes of CHD neonates across centres did not differ (p = 0.068): UBC (median = 84.6 mm 3 , IQR = 26–174.7 mm 3 ); UCSF (median = 104 mm 3 , IQR = 44–243 mm 3 ); UCZ (median = 121 mm 3 , IQR = 68–200.8 mm 3 ). The spatial distribution of WMI in CHD neonates showed strong concordance across centres with predilection for anterior and posterior rather than central lesions. Predominance of anterior lesions was apparent on the post-operative WMI map relative to the pre-operative map. Lower GA at birth predicted an increasing volume of WMI across the full cohort (41.1 mm 3 increase of WMI per week decrease in gestational age; 95% CI 11.5–70.8; p = 0.007), when accounting for centre and heart lesion. While WMI in term CHD and preterm neonates occurs most commonly in the intermediate zone/outer subventricular zone there is a paucity of central lesions in the CHD neonates relative to preterms. Conclusions: WMI in term neonates with CHD occurs in a characteristic topology. The spatial distribution of WMI in term neonates with CHD reflects the expected maturation of pre-oligodendrocytes such that the central regions are less vulnerable than in the preterm neonates

Communication Impairments in Early Term and Late Preterm Children: A Prospective Cohort Study following Children to Age 36 Months

OBJECTIVE To investigate the risk of communication impairments at age 18 and 36 months in children born early term (gestational weeks 37-38) and late preterm (gestational weeks 34-36). STUDY DESIGN A total of 39 423 children and their mothers participated in the Norwegian Mother and Child Cohort Study. The sample included 7109 children (18%) born early term and 1673 (4.2%) born late preterm. Information on gestational age and prenatal and postnatal risk factors was obtained from the Medical Birth Registry of Norway. Information on communication impairments was assessed using standardized questionnaires filled out by the mothers. Stepwise logistic regression analysis was applied to explore the associations between early term/late preterm birth and communication impairments at age 18 and 36 months. RESULTS Compared with children born at term, children born early term and late preterm had an increased risk of communication impairments at age 18 and 36 months. In early term, the aOR was 1.27 (95% CI, 1.12-1.44) at 18 months for communication impairments and 1.22 (95% CI, 1.07-1.39) at 36 months for expressive language impairments. In late preterm, the aOR was 1.74 (95% CI, 1.41-2.14) at 18 months and 1.37 (95% CI, 1.09-1.73) at 36 months. CONCLUSION Not only children born late preterm, but also those born early term, are at increased risk for communication impairments. Given the large number of children potentially affected, this may result in significant health care costs

Predictors of quality of life in young adults with congenital heart disease

Aims: The aim of this study was to identify medical and psychosocial risk factors for impaired health-related quality of life (HRQoL) and poor psychological adjustment (PA) in young adults with congenital heart disease (CHD). Methods and Results: A group of 188 patients (43% females, ages 18-30 years) with various types of CHD and 139 age-matched healthy controls (57% females) completed questionnaires assessing HRQoL, PA, social support, significant life events in the past year, education level, civil status, and employment status. Medical variables were retrieved from the patients' hospital records. Patients reported worse physical HRQoL than controls but similar mental HRQoL and PA. Female CHD patients showed worse physical and mental HRQoL and poorer PA than males. In CHD patients, a lower educational level and lower physical exercise capacity predicted lower physical HRQoL, but complexity of CHD was not related to HRQoL or PA. Less social support was associated with lower mental HRQoL and poorer PA in CHD patients. Conclusion: Young adults with CHD have impaired physical HRQoL but normal mental HRQoL and PA. Lower physical exercise capacity, female sex, less social support and lower educational level predict an unfavorable quality of life and PA. This subgroup of patients should be monitored more closely and provided with special psychosocial care to improve long-term outcome

A Uniform Description of Perioperative Brain MRI Findings in Infants with Severe Congenital Heart Disease:Results of a European Collaboration

BACKGROUND AND PURPOSE: A uniform description of brain MR imaging findings in infants with severe congenital heart disease to assess risk factors, predict outcome, and compare centers is lacking. Our objective was to uniformly describe the spectrum of perioperative brain MR imaging findings in infants with congenital heart disease. MATERIALS AND METHODS: Prospective observational studies were performed at 3 European centers between 2009 and 2019. Brain MR imaging was performed preoperatively and/or postoperatively in infants with transposition of the great arteries, single-ventricle physiology, or left ventricular outflow tract obstruction undergoing cardiac surgery within the first 6 weeks of life. Brain injury was assessed on T1, T2, DWI, SWI, and MRV. A subsample of images was assessed jointly to reach a consensus. RESULTS: A total of 348 MR imaging scans (180 preoperatively, 168 postoperatively, 146 pre- and postoperatively) were obtained in 202 infants. Preoperative, new postoperative, and cumulative postoperative white matter injury was identified in 25%, 30%, and 36%; arterial ischemic stroke, in 6%, 10%, and 14%; hypoxic-ischemic watershed injury in 2%, 1%, and 1%; intraparenchymal cerebral hemorrhage, in 0%, 4%, and 5%; cerebellar hemorrhage, in 6%, 2%, and 6%; intraventricular hemorrhage, in 14%, 6%, and 13%; subdural hemorrhage, in 29%, 17%, and 29%; and cerebral sinovenous thrombosis, in 0%, 10%, and 10%, respectively. CONCLUSIONS: A broad spectrum of perioperative brain MR imaging findings was found in infants with severe congenital heart disease. We propose an MR imaging protocol including T1-, T2-, diffusion-, and susceptibility-weighted imaging, and MRV to identify ischemic, hemorrhagic, and thrombotic lesions observed in this patient group
