Is environmental lead exposure associated with visit-to-visit systolic blood pressure variability in the US adults?
This study documents a positive linear relationship between environmental lead exposure and systolic blood pressure variability. Screening adults with fluctuating blood pressure for lead exposure could be warranted.
The homozygous SMN2 deletion (2 : 0) was statistically more frequent and associated with earlier onset age and lower MRC scale in Korean sALS patients. These suggest that SMN2 deletion may be one of the factors associated with susceptibility to and severity of sALS in a Korean population.
