Computer Adaptive vs. Non-adaptive Medical Progress Testing: Feasibility, Test Performance, and Student Experiences.

Background: Computerized adaptive testing tailors test items to students' abilities by adapting difficulty level. This more efficient, and reliable assessment form may provide advantages over a conventional medical progress test (PT). Prior to our study, a direct comparison of students' performance on a computer adaptive progress test (CA-PT) and a conventional PT, which is crucial for nationwide implementation of the CA-PT, was missing.

Mental Health of School-Aged Children Treated with Propranolol or Atenolol for Infantile Hemangioma and Their Parents.

Background: Infants with infantile hemangioma (IH) have been effectively treated with propranolol or atenolol. Concerns were raised about the mental health of these children at school age, due to central nervous system effects of propranolol and visible nature of IH.

Objective: This study aimed to compare the mental health at school age of children treated with propranolol to children treated with atenolol for IHs and their parents.

Prognostic Factors for Long-term Aesthetic Outcome of Infantile Haemangioma Treated with Beta-blockers.

Parents of infants treated with beta-blockers for infantile haemangioma are often concerned about the long-term aesthetic outcome. This cross-sectional study assessed the influence on the long-term aesthetic outcome of characteristics of the infantile haemangioma, the beta-blocker treatment, and the infant. The study included 103 children aged 6-12 years, treated with beta-blockers (propranolol or atenolol) for infantile haemangioma during infancy (age at treatment initiation ≤1 year) for ≥6 months.

Magnitude and relevance of change in health-related quality of life in patients with vascular malformations treated with sirolimus.

Introduction: Vascular malformations are rare congenital anomalies of the vascular system, which can involve the capillaries, veins, arteries, lymphatics, or a combination of vessel types. Patients with vascular malformations experience an impaired health-related quality of life (HRQoL) because of their symptoms (e.g.

Clinical differences in sirolimus treatment with low target levels between children and adults with vascular malformations - A nationwide trial.

The clinical presentation of patients with slow-flow vascular malformations is very heterogeneous. High clinical burden and subsequent reduced health-related quality of life is something they have in common. There is an unmet medical need for these patients for whom regular treatments like surgery and embolization are either insufficient or technically impossible.

Long-term neurocognitive functioning of children treated with propranolol or atenolol for infantile hemangioma.

Unlabelled: The purpose of this study was to compare long-term neurocognitive functioning (working memory, processing speed, and attention) between children who had been treated with either propranolol or atenolol for infantile hemangioma during infancy. All eligible children (n = 158) aged 6 years or older and treated with propranolol or atenolol as infants were invited to participate in this two-center cross-sectional study. The primary outcome was the Wechsler Intelligence Scale for Children-V Cognitive Proficiency Index (CPI), a measure of working memory, processing speed, and attention.

Identifying trajectories of fatigue in patients with primary mitochondrial disease due to the m.3243A > G variant.

Severe fatigue is a common complaint in patients with primary mitochondrial disease. However, less is known about the course of fatigue over time. This longitudinal observational cohort study of patients with the mitochondrial DNA 3243 A>G variant explored trajectories of fatigue over 2 years, and characteristics of patients within these fatigue trajectories.

Aesthetic Outcome of Propranolol vs Atenolol Treatment of Children with Infantile Haemangioma.

Infantile haemangiomas are common benign tumours of infancy, which can be treated effectively with beta-blockers such as propranolol and atenolol. Different types of beta-blockers may result in different long-term aesthetic outcomes. This study evaluated the difference in long-term aesthetic outcomes between infantile haemangiomas treated with either propranolol or atenolol, including the perspective of physicians, parents, and children.

Early MRI diagnosis of Sturge Weber Syndrome type 1 in infants.

Background: Patients with Sturge-Weber syndrome type 1 (SWS1) have a port-wine birthmark (PWB) as cutaneous hallmark. Up to 35% of neonates with a high risk PWB develop SWS1. Clinical manifestations are severe and often progressive.

Infantile fibrosarcoma with an EGFR kinase domain duplication: Underlining a close relationship with congenital mesoblastic nephroma and highlighting a similar morphological spectrum.

Infantile fibrosarcoma (IFS) and congenital mesoblastic nephroma (CMN) are locally aggressive tumors primarily occurring in infants. Both IFS and the cellular subtype of CMN show overlapping morphological features and an ETV6-NTRK3 fusion, suggesting a close relationship. An activating alteration of EGFR, based on an EGFR kinase domain duplication (KDD), occurs in a subset of CMNs lacking an NTRK3 rearrangement, especially in the classic and mixed type.

Amongst them are 24 AI companies that did so by posting a commitment of the kind on their website and/or by joining the 'Partnership on AI'.

Emotional and Behavioral Problems in Children With a Cleft Lip With or Without Palate or an Infantile Hemangioma.

Objective: Life can be challenging for children with a visible difference due to a medical condition, and they might be at risk for emotional and behavioral problems. This study examines emotional and behavioral problems in children with a cleft lip with or without palate (CL ± P) or an infantile hemangioma (IH) in relation to the visibility of the condition, the presence of additional condition-related problems, and parental affect.

Setting: This cross-sectional study took place in an academic medical hospital in the Erasmus MC Sophia Children's Hospital, the Netherlands.

Patients with Congenital Low-Flow Vascular Malformation Treated with Low Dose Sirolimus.

Introduction: Patients with congenital vascular malformations often suffer from an impaired quality of life (QoL) because of pain and functional disabilities. Previous studies have shown that the mTOR inhibitor sirolimus can reduce complaints and improve QoL in some patients. High target levels of sirolimus of 10-15 ng/ml were well tolerated; however, in a relative high percentage of patients sirolimus caused serious adverse events (AEs).

Parenting Children With a Cleft Lip With or Without Palate or a Visible Infantile Hemangioma: A Cross-Sectional Study of Distress and Parenting Stress.

Objective: Parents of children with a medical condition and a visible difference can experience challenging situations. We evaluated distress and parenting stress in parents of children with a cleft lip with or without cleft palate (CL±P) or a visible infantile hemangioma (IH).

Setting: This cross-sectional study took place in an academic medical hospital in Rotterdam, the Netherlands.

One mutation, three phenotypes: novel metabolic insights on MELAS, MIDD and myopathy caused by the m.3243A > G mutation.

Introduction: The m.3243A > G mitochondrial DNA mutation is one of the most common mitochondrial disease-causing mutations, with a carrier rate as high as 1:400. This point mutation affects the MT-TL1 gene, ultimately affecting the oxidative phosphorylation system and the cell's energy production.

Six-year prospective follow-up study in 151 carriers of the mitochondrial DNA 3243 A>G variant.
