Use of murine models for the study of obstructive sleep apnea syndrome in Down syndrome
Rev Mal Respir. 2024 Mar 8:S0761-8425(24)00140-2. doi: 10.1016/j.rmr.2024.02.010. Online ahead of print.ABSTRACTDown syndrome (DS), or trisomy 21, is a genetic disorder caused by the presence of an extra copy of chromosome 21, leading to various characteristic physical features as well as developmental and cognitive delays. Obstructive sleep apnea syndrome (OSAS) is a common disorder in both adult and pediatric patients with DS. Several characteristics of DS may contribute to the development or worsening of OSAS. Numerous murine models of DS exist. A number of studies have explored apneas and the risk of upper airway obstr...

Cancers, Vol. 16, Pages 1103: Cancer Risk in Patients with Down Syndrome & mdash;A Retrospective Cohort Study from Germany
Conclusions: Our results could form the basis for future studies to clarify whether and to what extent an adapted screening program needs to be modified for individuals with Down syndrome due to the particular cancer distribution pattern. (Source: Cancers)

Trisomy silencing by XIST: translational prospects and challenges
This article combines elements of a review on XIST biology with our perspective on the translational prospects and challenges of XIST transgenics. We first briefly review aspects of XIST RNA basic biology that are key to its translational relevance, and then discuss recent efforts to develop translational utility of XIST for chromosome dosage disorders, particularly Down syndrome (DS). Remarkably, it was shown  in vitro that expression of an XIST transgene inserted into one chromosome 21 can comprehensively silence that chromosome and “dosage compensate” Trisomy 21, the cause of DS. Here we summarize recent findings ...

Listening to the voices of mothers in Indonesia: Qualitative content analysis of experiences in parenting children with down syndrome
Generally, mothers provide the majority of caring for children who have Down syndrome. They pose challenges not only with regard to the acceptability of the child situation but also with regard to the provision of care for children with DS. (Source: Journal of Pediatric Nursing)

Unusual Finding in a Boy with Recurrent Epididymo-Orchitis and Normal External Genitalia
A 1-year-old boy with Down syndrome presented to the emergency department due to his third episode of epididymo-orchitis (EO). He was previously treated with trimethoprim-sulfamethoxazole. His parents reported irritability, fever, and inflammation of the right testis. Scrotal examination revealed an enlarged, tender right testicle without overlying skin changes, hypospadias, or cryptorchidism. Testicular ultrasound showed signs suggestive of right EO, and urine culture was positive for Pseudomonas Aeruginosa. (Source: Urology)

Validation of factor structure of the neurodevelopmental parent report for outcome monitoring in down syndrome: confirmatory factor analysis
DiscussionThe ND-PROM has a desirable factor structure and is a valid and clinically useful tool that captures a range of distinct and independent areas of developmental and behavioral functioning in DS, for individuals with and without an ASD diagnosis. (Source: Frontiers in Psychiatry)

Trisomy 21 Alters Cell Proliferation and Migration of iPSC-Derived Cardiomyocytes on Type VI Collagen
CONCLUSIONS: These results suggest that the increased expression of COLVI in DS may result in lower migration-driven elongation of endocardial cushions stemming from lower cell proliferation and migration, possibly contributing to the high incidence of CHD in the DS population.SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1007/s12195-023-00791-x.PMID:38435791 | PMC:PMC10901762 | DOI:10.1007/s12195-023-00791-x (Source: Molecular Medicine)

However, the main drivers behind these disparate health outcomes remain unknown. Herein we performed experimental infections with S...
