Malignant rhabdoid tumor (MRT) is one of the most aggressive childhood cancers for which no effective treatment options are available. Reprogramming of cellular metabolism is an important hallmark of cancer, with various metabolism-based drugs being approved as a cancer treatment. In this study, we use patient-derived tumor organoids (tumoroids) to map the metabolic landscape of several pediatric cancers.

Randomized controlled trials (RCTs) are at the top of the pyramid of evidence as they offer the best answer on the efficacy of a new treatment. RCTs are true experiments in which participants are randomly allocated to receive a certain intervention (experimental group) or a different intervention (comparison group), or no treatment at all (control or placebo group). Randomization, along with other methodological features such as blinding and allocation concealment, safeguard against biases.

Exploring the "shared" in shared decision-making in the care for children with chronic diseases or disabilities: what are the roles of parents and professionals?

Eur J Pediatr

Department of Educational and Family Studies, Faculty of Behavioural and Movement Sciences, Amsterdam Public Health Research Institute, Vrije Universiteit Amsterdam, Amsterdam, The Netherlands.

There is a growing body of literature that recognizes the importance of shared decision-making (SDM) in the care for children with chronic conditions and/or disabilities. Although participation in SDM can be more or less active, the tuning between parents and professionals about the way they want to participate in SDM is often an implicit process, limiting parents' optimal involvement. Role definitions may support both partners in the process of SDM.

Background: Early-onset fetal growth restriction as consequence of placental insufficiency frequently requires iatrogenic, preterm birth. Administration of antenatal corticosteroids reduces risks of neonatal morbidity and mortality following preterm birth and is most beneficial if the neonate is delivered within two weeks following treatment. International guidelines on fetal growth restriction pregnancies do not provide directives regarding the timing of antenatal corticosteroids, resulting in practice variation.

Intercellular communication via extracellular vesicles (EVs) has been identified as a vital component of a steadily expanding number of physiological and pathological processes. To accommodate these roles, EVs have highly heterogeneous molecular compositions. Given that surface molecules on EVs determine their interactions with their environment, EV functionality likely differs between subpopulations with varying surface compositions.

Despite advances in allogeneic hematopoietic cell transplantation (HCT), poor graft function (PGF) remains an important complication with substantial morbidity and mortality. The investigation of preventive and therapeutic PGF treatments is hindered by inconsistencies in reported incidence and outcomes across studies, which may be explained by heterogeneity in PGF definition. To assess the impact of definition heterogeneity, we conducted a multicenter study, analyzing over 35.

TTC7A missense variants in intestinal disease can be classified by molecular and cellular phenotypes.

Hum Mol Genet

December 2024

Division of Pediatric Gastroenterology, Wilhelmina Children's Hospital, University Medical Center Utrecht, Lundlaan 6 3584 EA Utrecht, The Netherlands.

Biallelic mutations in tetratricopeptide repeat domain 7A (TTC7A) give rise to intestinal and immune disorders. However, our understanding of the genotype-phenotype relationship is limited, because TTC7A variants are mostly compound heterozygous and the disease phenotypes are highly diverse. This study aims to clarify how different TTC7A variants impact the severity of intestinal epithelial disorders.

Introduction: Tracheomalacia (TM) often occurs in children with oesophageal atresia (OA), leading to recurrent respiratory symptoms and in severe cases to blue spells or ultimately respiratory arrest. In some patients, a secondary posterior tracheopexy may then be indicated. This secondary surgery, as well as respiratory morbidity, may be prevented by performing a primary posterior tracheopexy (PPT) concurrent with primary OA correction.

Isoleucine-to-valine substitutions support cellular physiology during isoleucine deprivation.

Nucleic Acids Res

Department of Metabolic Diseases, Wilhelmina Children's Hospital, University Medical Center Utrecht, Lundlaan 6, 3584 EA Utrecht, The Netherlands.

Aminoacyl-tRNA synthetases (ARSs) couple tRNAs with their corresponding amino acids. While ARSs can bind structurally similar amino acids, extreme specificity is ensured by subsequent editing activity. Yet, we found that upon isoleucine (I) restriction, healthy fibroblasts consistently incorporated valine (V) into proteins at isoleucine codons, resulting from misacylation of tRNAIle with valine by wildtype IARS1.

Low social support has been identified as a risk factor for maternal perinatal mental health problems. However, previous studies have predominantly focused on general social support or support from the partner, often overlooking the roles of grandparents. This mini review discusses recent developments in perinatal health research showing that supportive grandparents may constitute a protective factor against the development of maternal perinatal mental health problems.

Children born with defective heart valves require multiple donor valve replacements throughout life, because these cannot grow and can cause early failure through immune degeneration. This study tests the lentiviral delivery of viral immune evasion genes US2 and human serpin 9 to shield human heart valves from immune rejection. The results show we can efficiently down-regulate human leukocyte antigen expression in heart valve cells and in intact heart valve tissue resulting in decreased activity of a human leukocyte antigen-reactive CD8+ T-cell clone without inducing cytotoxicity.

Many children suffer from neurodevelopmental aberrations that have long-term effects. To understand the consequences of pathological processes during particular periods in neurodevelopment, one has to understand the differences in the developmental timelines of brain regions. The cerebellum is one of the first brain structures to differentiate during development but one of the last to achieve maturity.
