Background: This study aims to explore the association between the quality of life (QoL) in children with Down syndrome (DS) and its relationship with demographic characteristics of both parents and children. The investigation encompasses five domains: physical and psychological well‐being, autonomy and parental relationship, social well‐being, and peers, as well as school and the learning environment. Method: An online questionnaire, the KIDSCREEN‐27, was used to measure the QoL of 112 families with DS in Saudi Arabia, referred to as "Parent‐Reported Measures." Descriptive statistics were analyzed using the Statistical Package for Social Sciences. Results: The study found that the QoL of children with DS showed high scores in the psychological well‐being, autonomy, parental relations, school, and learning environment domains. However, the physical and social well‐being and peer domains had lower scores, although still considered "good scores." Family income had a positively significant influence on all QoL domains. Specifically, higher family income was associated with better QoL outcomes, except for social well‐being. Parental age was found to influence psychological well‐being, while parental education and the relationship between the parent and child influenced social well‐being. Lastly, the child's gender was found to have an impact on the school and learning environment domain. Conclusion: The study highlights the importance of understanding the impact of the demographic variability of children with DS and their parents on the QoL of their children. It emphasizes the need to address the needs of families with lower incomes and the importance of parental education and relationships with their children in improving social well‐being. The findings could aid policymakers and healthcare providers in improving the QoL for families with children who have DS. This study aims to determine the relationship between demographic variables of parents with down syndrome (DS) children and their quality of life (QoL). It is the first time to use the Arabic version KIDSCREEN questionnaire, after validation. This is the first study to measure the demographic variables influence on the reported QoL of children with DS. This study found that family income influenced all QoL domains except social well‐being. Psychological well‐being was influenced by parental age. Social well‐being was influenced by parental education. Finally, the school and learning environment was influenced by the child's gender. [ABSTRACT FROM AUTHOR]

Oxidative stress has been hypothesized to play a crucial role in the complications of type 2 diabetes (T2D). Hyperglycaemia-mediated increases in free radicals have a deleterious effect on cellular compartments and nucleic acids, leading to imbalances between free radicals and antioxidant enzymes. This case–control study comprised two groups with 100 participants (50 T2D and 50 DN patients) and aimed to examine the association between single-nucleotide polymorphisms (SNPs) in the genes encoding nicotinamide adenine dinucleotide phosphate oxidase (NOX), glutathione S-transferase P (GSTP1), and glutathione peroxidase 1(GPX1) and diabetic nephropathy (DN) risk in patients with T2D. An SNP genotyping assay was performed using TaqMan assay and real-time PCR to identify the SNPs (NOX rs4673, GSTP rs1695, GPX1 rs1050450). The Sanger method was used to validate our findings. Fisher chi-square analyses revealed no significant differences in these genes when comparing T2D patients with and without DN. Our findings suggest no association between the rs4673, rs1695, and rs1050450 SNPs and DN in Saudi patients with T2D. [ABSTRACT FROM AUTHOR]

Background: Hereditary spastic paraplegias (HSP), a group of genetically heterogeneous neurological disorders with more than 56 documented loci (SPG1-56), are described either as uncomplicated (or pure), or complicated where in addition to spasticity and weakness of lower extremeties, additional neurological symptoms are present, including dementia, loss of vision, epilepsy, mental retardation and ichthyosis. We identified a large consanguineous family of Indian descent with four affected members with childhood onset HSP (SPG54), presenting with upper and lower limb spasticity, mental retardation and agenesis of the corpus callosum. Results: A common region of homozygosity on chromosome 8 spanning seven megabases (Mb) was identified in the affected individuals using the Illumina human cytoSNP-12 DNA Analysis BeadChip Kit. Exome sequencing identified a homozygous stop gain mutation (pR287X) in the phospholipase A, gene DDHD2, in the affected individuals, resulting in a premature stop codon and a severely truncated protein lacking the SAM and DDHD domains crucial for phosphoinositide binding and phospholipase activity. Conclusion: This mutation adds to the knowledge of HSP, suggests a possible founder effect for the pR287X mutation, and adds to the list of genes involved in lipid metabolism with a role in HSP and other neurodegenerative disorders.
