Are families with adolescents and young adults with cerebral palsy the same as other families?

This study compared adolescents with cerebral palsy (CP) and their families to adolescents without physical disabilities and their families as the child enters and leaves adolescence (age ranges 13 to 15 years and 19 to 23 years). Families of 90 individuals with CP (42 females, 48 males) and 75 individuals without physical disabilities (34 females, 41 males) participated. They completed the Family Assessment Device, Life Situation Survey, Multidimensional Scale of Perceived Social Support, and Future Questionnaire. There were few differences in family functioning, life satisfaction, or perceived social support between the groups. Expectations of young adults with CP and parents of both adolescents and young adults regarding future independence and success were lower than the expectations of the control group. While the group results emphasize similarities between families during the two stages of adolescence, individual families and individual family members report specific challenges.

Constitutively increased micronuclei are predominantly caused by acentric fragments.

The frequency of kinetochore (centromere)-positive micronuclei (MN) was determined in 32 fibroblast cell lines. We tested 16 probands with spontaneously high MN levels (greater than or equal to 20 MN/500 cells (4%] and 8 probands (controls) with low MN levels (less than or equal to 13 MN/500 cells (2.6%]. To study whether the elevation of MN levels is due to increased chromosomal breakage we used the antikinetochore antibody fluorescent staining method. Probands with spontaneously high MN had kinetochore-positive MN increased by a factor 2.1 compared to the controls whereas the kinetochore-negative MN were increased by a factor 6.14. This shows that spontaneous elevation of MN is mainly caused by increased chromosomal breakage and only in a minor proportion by chromosome segregation errors as a consequence of spindle defects.
