Perfluorodecanoic acid (PFDA) increases oxidative stress through inhibition of mitochondrial β-oxidation.

PER: and polyfluoroalkyl substances (PFAS) are a large group of synthetic organic chemicals that are ubiquitous environmental pollutants. Among PFAS, perfluorodecanoic acid (PFDA) is one of the most toxic compounds, but the molecular basis behind its toxicity is not fully understood. In an interspecies comparison with placental cells (HTR-8/SVneo) and zebrafish embryos, we demonstrate that PFDA induces mitochondrial dysfunction and impairs fatty acid β-oxidation.

ATP1A3 dysfunction causes motor hyperexcitability and afterhyperpolarization loss in a dystonia model.

Mutations in the gene encoding the alpha3 Na+/K+-ATPase isoform (ATP1A3) lead to movement disorders that manifest with dystonia, a common neurological symptom with many different origins, but for which the underlying molecular mechanisms remain poorly understood. We have generated an ATP1A3 mutant mouse that displays motor impairments and a hyperexcitable motor phenotype compatible with dystonia. We show that neurons harboring this mutation are compromised in their ability to extrude raised levels of intracellular sodium, highlighting a profound deficit in neuronal sodium homeostasis.

Effectiveness of structured, multidisciplinary long-term care for pediatric cancer survivors: protocol of the multicenter, randomized-controlled AELKI study.

Background: In Germany, around 2.250 children and adolescents are diagnosed with cancer each year. Despite generally positive long-term survival rates, many patients must cope with late effects of the disease and its treatment.

Research areas and trends in family-centered care in the 21st century: a bibliometric review.

Introduction: Family-centered care (FCC) is a model of care provision that sees a patient's loved ones as essential partners to the health care team and positively influences the psychological safety of patients and loved ones.

Objectives: This review aims to present an overview of impactful publications, authors, institutions, journals, countries, fields of application and trends of FCC in the 21 century as well as suggestions on further research.

Methods: The Web of Science Database was searched for publications on FCC between January 2000 and Dezember 2023.

An online, two-day educational seminar had no impact on disease-specific knowledge in patients with systemic sclerosis.

Systemic sclerosis (SSc) is a multifaceted disease, and its diagnosis triggers substantial anxiety and uncertainty for those affected. Currently, there are no valid data describing the impact of disease-specific patient education on the disease knowledge available. We created a two-day, online educational seminar to provide SSc patients with disease-specific information.

"Delabeling" by direct provocation testing in children and adolescents with a suspected history of a delayed reaction to β-lactam antibiotics: Consensus paper of Gesellschaft für pädiatrische Allergologie und Umweltmedizin (GPAU), Deutsche Gesellschaft für Allergologie und klinische Immunologie (DGAKI), and Ärzteverband deutscher Allergologen (ÄDA).

Background: Approximately 10% of European children are classified as allergic to drugs. In the majority of these children, no allergy to β-lactam antibiotics (BLA) can be found. In most cases, the exanthema is caused by the infection.

Altered Serum Proteins Suggest Inflammation, Fibrogenesis and Angiogenesis in Adult Patients with a Fontan Circulation.

Previous omics research in patients with complex congenital heart disease and single-ventricle circulation (irrespective of the stage of palliative repair) revealed alterations in cardiac and systemic metabolism, inter alia abnormalities in energy metabolism, and inflammation, oxidative stress or endothelial dysfunction. We employed an affinity-proteomics approach focused on cell surface markers, cytokines, and chemokines in the serum of 20 adult Fontan patients with a good functioning systemic left ventricle, and we 20 matched controls to reveal any specific processes on a cellular level. Analysis of 349 proteins revealed 4 altered protein levels related to chronic inflammation, with elevated levels of syndecan-1 and glycophorin-A, as well as decreased levels of leukemia inhibitory factor and nerve growth factor-ß in Fontan patients compared to controls.

Deoxyguanosine kinase deficiency: natural history and liver transplant outcome.

Autosomal recessive pathogenetic variants in the gene cause deficiency of deoxyguanosine kinase activity and mitochondrial deoxynucleotides pool imbalance, consequently, leading to quantitative and/or qualitative impairment of mitochondrial DNA synthesis. Typically, patients present early-onset liver failure with or without neurological involvement and a clinical course rapidly progressing to death. This is an international multicentre study aiming to provide a retrospective natural history of deoxyguanosine kinase deficient patients.

Risk and time preferences in individuals with lifestyle-related and non-lifestyle-related cardiovascular diseases: a pilot study.

Objectives: To (1) pilot a study of behavioural characterisation based on risk and time preferences in clinically well-characterised individuals, (2) assess the distribution of preferences in this population and (3) explore differences in preferences between individuals with 'lifestyle-related' (LS) and 'non-lifestyle-related' (NLS) cardiovascular diseases.

Design: Cross-sectional study with an economic online experiment to collect risk and time preferences, a detailed clinical characterisation and a sociodemographic and lifestyle survey. A definition of LS and NLS groups was developed.

A Multimodal Lifestyle Psychosocial Survivorship Program in Young Cancer Survivors: The CARE for CAYA Program-A Randomized Clinical Trial Embedded in a Longitudinal Cohort Study.

Importance: There is a lack of trials examining the effect of counseling interventions for child, adolescent, and younger adult (CAYA) cancer survivors.

Objective: To assess lifestyle habits and the psychosocial situation of CAYAs to determine the efficacy of needs-based interventions in the CARE for CAYA program (CFC-P).

Design, Setting, And Participants: The CFC-P was conducted as a multicenter program in 14 German outpatient clinics, mainly university cancer centers.

[Hospital-based Home Care for Children with Cancer from the Parents̓ Point of View - A Qualitative Exploration of Family Members].

Background: About 2,200 children and adolescents in Germany per year are diagnosed with oncological diseases. Through now, there are almost no offers for home care services for these patients. There is a pilot program offering hospital-based home care for children and adolescents with cancer in Germany.

5qSMA: standardised retrospective natural history assessment in 268 patients with four copies of SMN2.

Newborn screening for 5qSMA offers the potential for early, ideally pre-symptomatic, therapeutic intervention. However, limited data exist on the outcomes of individuals with 4 copies of SMN2, and there is no consensus within the SMA treatment community regarding early treatment initiation in this subgroup. To provide evidence-based insights into disease progression, we performed a retrospective analysis of 268 patients with 4 copies of SMN2 from the SMArtCARE registry in Germany, Austria and Switzerland.

Music Therapy as a Topic in Medical Education: Course Concept and Student Evaluation of an Elective Course for Medical Students.

Objectives: Music therapy has been proven as a safe and well-established intervention in healthcare to relieve symptoms and improve quality of life. While music therapy is already established in several settings to supplement medical care, there is a lack of integration in the field of medical education.

Methods: We report on the implementation and evaluation of a teaching concept for a five-day-intensive-course on music therapy.

Translation and cross-cultural adaptation of the young children participation and environment measure for its use in Austria, Germany, and Switzerland.

Background: Concepts such as participation and environment may differ across cultures. Consequently, cultural equivalence must be assured when using a measure like the Young Children Participation and Environment Measure (YC-PEM) in other settings than the original English-speaking contexts. This study aimed to cross-culturally translate and adapt the YC-PEM into German as it is used in Germany, Austria, and Switzerland.

Severity-adjusted evaluation of liver transplantation on health outcomes in urea cycle disorders.

Purpose: Liver transplantation (LTx) is performed in individuals with urea cycle disorders when medical management (MM) insufficiently prevents the occurrence of hyperammonemic events. However, there is a paucity of systematic analyses on the effects of LTx on health-related outcome parameters compared to individuals with comparable severity who are medically managed.

Methods: We investigated the effects of LTx and MM on validated health-related outcome parameters, including the metabolic disease course, linear growth, and neurocognitive outcomes.

New description of an MRPS2 homozygous patient: Further features to help expend the phenotype.

Mutated mito-ribosomal protein S2 (MRPS2) was already described in only three subjects, two with sensorineural hearing impairment, mild developmental delay, hypoglycemia, lactic acidemia and combined oxidative phosphorylation system deficiency and another, recently, presenting with a less severe phenotype. In order to expand the phenotype, we describe a new MRPS2 homozygous subject who shows particular features which have not yet been reported: initial microcephaly, joint hypermobility and autistic features.

Survival in primary hemophagocytic lymphohistiocytosis, 2016 to 2021: etoposide is better than its reputation.

Primary hemophagocytic lymphohistiocytosis (pHLH) is a life-threatening hyperinflammatory syndrome that develops mainly in patients with genetic disorders of lymphocyte cytotoxicity and X-linked lymphoproliferative syndromes. Previous studies with etoposide-based treatment followed by hematopoetic stem cell transplantation (HSCT) resulted in 5-year survival of 50% to 59%. Contemporary data are lacking.

Myeloid leukemia vulnerabilities embedded in long noncoding RNA locus .

The noncoding genome presents a largely untapped source of new biological insights, including thousands of long noncoding RNA (lncRNA) loci. While lncRNA dysregulation has been reported in myeloid malignancies, their functional relevance remains to be systematically interrogated. We performed CRISPRi screens of lncRNA signatures from normal and malignant hematopoietic cells and identified as a myeloid leukemia dependency.
