Introduction: Patients with inflammatory bowel disease (IBD) are predisposed to the reactivation of viral infections such as cytomegalovirus (CMV). Clinical discrimination of disease flares and colonic CMV reactivation is difficult in patients with established diagnosis of IBD, and there are no reliable noninvasive diagnostic tools yet. Furthermore, the influence of novel therapeutics including biologicals and Janus kinase inhibitors on the risk of CMV colitis is unclear.

Article Synopsis
  • Hypoplastic left heart syndrome (HLHS) is a serious heart defect involving underdevelopment of the left ventricle and associated structures, leading to significant health risks despite advances in treatment.
  • Genetic factors play a key role in HLHS, with links to cytogenetic abnormalities, familial patterns, and identified genomic regions, suggesting a hereditary basis.
  • Identifying specific genetic causes is challenging; HLHS appears to result from complex inheritance rather than a single variant, prompting researchers to adopt more sophisticated models in their studies.

: Patients with congenital heart disease (CHD), especially as a concomitant syndromal disease of trisomy 21 (T21), are at risk for impaired neurodevelopment. This can also affect these patients' education. However, there continues to be a research gap in the educational development of CHD patients and T21 CHD patients.

Objectives: This study aims to evaluate the school careers of patients with congenital heart disease (CHD) and microcephaly.

Methods: An exploratory online survey was conducted on patients from a previous study on somatic development in children with CHD in 2018 ( = 2818). A total of 750 patients participated in the online survey (26.

Objectives: Very low birthweight (<1500 g, VLBW) infants with severe congenital heart defect (CHD) are at increased risk for perinatal and operative mortality. This study aims to describe morbidity, long-term mortality and neuro-developmental outcome in early childhood in VLBW infants who received cardiac surgery for severe CHD within 1 year after birth.

Methods: Monocentric observational study on VLBW infants with severe CHD born between 2008 and 2017.

This study scrutinizes management and clinical presentation of severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) in pediatric inpatient care and evaluates the utilization of pediatric healthcare capacity during the pandemic. Within this retrospective cohort study, we systematically reviewed data of all 16,785 pediatric patients (<18 years admitted to our clinical center between January 2018 and June 2021). Data on SARS-CoV-2 test numbers, hospital admissions and clinical characteristics of infected patients were collected.

Infants with Congenital Heart Disease (CHD) are at risk for neurodevelopmental delays, emotional, social and behavioral difficulties. Hospitalization early in life and associated stressors may contribute to these challenges. Family-centered Care (FCC) is a health care approach that is respectful of and responsive to the needs and values of a family and has shown to be effective in improving health outcomes of premature infants, as well as the mental well-being of their parents.

Background: CNI-free immunosuppression with conversion to mTORi-based immunosuppression has been demonstrated to reduce CNI-toxicity and to exhibit anti-proliferative properties. However, the experience of CNI-free immunosuppression in paediatric heart transplantation is limited.

Methods: A retrospective analysis was conducted of 129 paediatric heart transplants performed between 1997 and 2015.

Background: The aim of the study was to evaluate the educational achievement of patients diagnosed with univentricular heart physiology (UVHP) or transposition of the great arteries (TGA) after neonatal cardiac surgery.

Methods: An exploratory online survey was performed with patients registered with the National Register for Congenital Heart Defects in Germany. For this publication, a subgroup analysis was conducted among patients diagnosed with TGA (n = 173; 36.

Objective: We developed the Long-term Early Development Research (LEADER) project to investigate the development of children with CHD and/or after cardiopulmonary resuscitation. Both populations are at risk for delays in motor, cognitive, and language development. However, few studies to date have investigated the longitudinal development in these children.

Therapeutic hypothermia during cardiac surgery has been widely used for neuroprotection and to attenuate the systemic inflammatory response due to cardiopulmonary bypass (CPB). Experimental data suggest that cold-shock protein RNA-binding motif 3 (RBM3), which is induced in response to hypothermia, plays a key role in hypothermia-induced organ protection. To date, investigation on RBM3 has been performed exclusively or in animal models, and the detection and regulation of RBM3 in human blood has not been investigated until now.

Unfavorable neurological outcome in children after cardiopulmonary resuscitation in infancy is frequent. However, few studies have investigated the development of these patients using comprehensive developmental tests and the feasibility of the Bayley Scales of Infant Development, 3rd Edition (BSID-III) has not been reported for this population. In this cross-sectional pilot study, we assessed the cognitive, language, and motor development in infants after cardiopulmonary resuscitation of ≥ 5 min with the BSID-III at the age of 12 or 24 months, depending on recruitment age.

Introduction: Congenital heart disease (CHD) is the most common birth defect. Studies on the development of children with CHD point towards deficits in motoric, cognitive and language development. However, most studies are cross-sectional and there is a gap in the knowledge concerning developmental trajectories, risk and protective factors and a lack of research concerning environmental predictors.

Unlabelled: We assessed the dynamics in the prevalence of children with congenital heart disease (CHD) and Down syndrome in Germany with regard to phenotype, severity, and gender. Data from patients with CHD and Down syndrome born between 1980 and 2014 were analyzed, who are registered with the German National Register for Congenital Heart Defects. One thousand six hundred eighteen CHD patients with Down syndrome were identified.

Objective: Therapeutic hypothermia is an established treatment for perinatal asphyxia. Yet, many term infants continue to die or suffer from neurodevelopmental disability. Several experimental studies have demonstrated a beneficial effect of mild-to-moderate hypothermia after hypoxic injury, but the understanding of hypothermia-induced neuroprotection remains incomplete.

To assess the level of graduation, the wish to have children and the course of pregnancy among former patients with childhood leukemia in comparison to the general German population and depending on gender, a nationwide survey was conducted in 2008. In total 63.6% (1476/2319) of the contacted survivors of childhood leukemia participated (mean age 25.

Aim: The aim of this study was to compare self-reported questionnaire-based information on fertility impairment with results from hormone analyses in women who underwent chemoradiotherapy during childhood and adolescence.

Material And Methods: In a cross-sectional study, questionnaires and hormone analyses (anti-Müllerian hormone [AMH], follicle-stimulating hormone, luteinizing hormone, estradiol, progesterone) were evaluated in 86 female former pediatric oncology patients in Berlin in 2009.

Results: Eighty-six women (median age 23 years, range 19-41) participated in the study with a median follow up of 14 years (range 2-30) after diagnosis.
