AI Article Synopsis
- A study examined the manual skills of 35 children with trisomy 21, aged 4-18, comparing their grasp characteristics during tasks with a matched group of typically developing children.
- Findings showed that children with trisomy 21 used fewer fingers and displayed distinct grasping patterns, often extending fingers that weren’t involved in the grip.
- While some grasping characteristics improved with age, others persisted, suggesting that the perceptual-motor development of children with trisomy 21 should be viewed as atypical rather than simply delayed.
Article Abstract
Children with trisomy 21 display atypical manual skills that change to some extent during development. We examined grasp characteristics and their development in 35 children with trisomy 21, aged 4-18 years, who performed simple manual tasks (two manual tasks of the Movement Assessment Battery for Children, and grasping of five wooden blocks whose size was determined by their hand size). The age-matched comparison group included 35 typically developing children. Children with trisomy 21 were found to use fewer fingers than children in the comparison group in each task. They also used specific grasps and tended to extend fingers that were not involved in the grip. While some specific grasp characteristics of children with trisomy 21 decreased with age, other did not, and remained present throughout development. The perceptual-motor development of children with trisomy 21 should be analyzed in terms of atypical development rather than developmental delay.

Center of Prenatal Diagnosis, Lianyungang Maternal and Child Health Care Hospital, Lianyungang, Jiangsu 222000, China.
Objective: To explore the clinical significance of trisomy 7 signaled by non-invasive prenatal testing (NIPT).
Methods: Pregnant women with high risk for trisomy 7 by NIPT from January 2017 to December 2023 were selected as the study subjects, and the results of prenatal diagnosis and follow-up were analyzed. Literature related to pregnant women with a high risk for trisomy 7 by NIPT from January 2016 to July 2024 was retrieved from China Biomedical Literature Database, Wanfang Database, China National Knowledge Infrastructure and PubMed database.

Background: Cell-free DNA (cfDNA) sequence analysis to screen for fetal aneuploidy can incidentally detect maternal cancer. Additional data are needed to identify DNA-sequencing patterns and other biomarkers that can identify pregnant persons who are most likely to have cancer and to determine the best approach for follow-up.
Methods: In this ongoing study we performed cancer screening in pregnant or postpartum persons who did not perceive signs or symptoms of cancer but received unusual clinical cfDNA-sequencing results or results that were nonreportable (i.

To assess the prenatal course and early postnatal outcomes of fetuses diagnosed with tricuspid atresia and to identify predictors of survival. This was a retrospective study of 25 fetuses diagnosed with tricuspid atresia in a single tertiary referral center, evaluating prenatal echocardiographic features and postnatal outcomes. A total of 4 of 29 initially diagnosed fetuses were excluded due to changes in diagnosis or loss to follow-up, leaving 25 fetuses for analysis.

Down syndrome (DS) or trisomy 21 (T21) is present in a significant number of children and adults around the world and is associated with cognitive and medical challenges. Through research, the T21 Research Society (T21RS), established in 2014, unites a worldwide community dedicated to understanding the impact of T21 on biological systems and improving the quality of life of people with DS across the lifespan. T21RS hosts an international conference every two years to support collaboration, dissemination, and information sharing for this goal.
