The Impact of Demographic Characteristics on Parenting Stress among Parents of Children with Disabilities: A Cross-Sectional Study.

Even though it is already known that parents of children with developmental delays or disabilities experience higher parenting stress than families of typically developing children, the contributing factors need to be analyzed in more detail. The aim of this cross-sectional study was to examine the influence of demographic characteristics on parenting stress from caring for a disabled child and to identify possible protective or additional stressful social factors. A total of 611 mothers and fathers of children with developmental delays, chronic diseases, or disabilities completed two questionnaires during their medical appointments at the Children's Development Center (CDC) of Leipzig University Hospital between June 2020 and February 2021.

Parenting stress in families of children with disabilities: Impact of type of disability and assessment of attending paediatricians.

Background: Parents of children with developmental disorders (DD) or disabilities report greater parenting stress than parents of typically developing children. To minimise this stress, stressful factors need to be known and stress needs to be recognised early. The present cross-sectional study aims to systematically assess and compare parenting stress in families of children with various types of disabilities.

Genotype-phenotype correlations in RHOBTB2-associated neurodevelopmental disorders.

Purpose: Missense variants clustering in the BTB domain region of RHOBTB2 cause a developmental and epileptic encephalopathy with early-onset seizures and severe intellectual disability.

Methods: By international collaboration, we assembled individuals with pathogenic RHOBTB2 variants and a variable spectrum of neurodevelopmental disorders. By western blotting, we investigated the consequences of missense variants in vitro.

A malignant triton tumor with an unbalanced translocation (1;13)(q10;q10) and an isochromosome (8)(q10) as the sole karyotypic abnormalities.

The karyotype of a malignant nerve sheath tumor with rhabdomyosarcomatous differentiation (malignant triton tumor) of a 58-year-old woman is reported. The tumor revealed an isochromosome for the long arm of chromosome 8 and an unbalanced translocation (1;13)(q10;q10) leading to a gain of the long arm of chromosome 1 as the sole karyotypic abnormalities.

Chromosomal translocations affecting 12q14-15 but not deletions of the long arm of chromosome 7 associated with a growth advantage of uterine smooth muscle cells.

Cytogenetically, uterine leiomyomata are the best investigated human tumours. The most frequent clonal abnormalities are structural rearrangements involving 12q14-15 and deletions of part of the long arm of chromosome 7. The present study investigated a possible growth advantage conferred by these abnormalities, when compared with myomata having an apparently normal karyotype.
