The goal of the present study was to determine whether age-related differences in the acute physiologic response to scaled cortical impact injury contribute to differences in vulnerability to traumatic brain injury (TBI).
Heart rate (HR), mean arterial pressure (MAP), brain temperature (BrT) and cerebral blood flow (CBF) were measured in 22 piglets (7 of age 5 days, 8 of age 1 month, 7 of age 4 months) at baseline and for 3 h following scaled cortical impact injury.
There were no age-dependent variations from baseline in HR, MAP or BrT following injury. CBF increased in the 5-day-old animals following injury while CBF in the 1- and 4-month-old animals decreased following injury (p = 0.0049).
CBF was shown to have a significant age-dependent response to TBI with the youngest animals exhibiting increased CBF following injury.
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 01 January 2014.
All research outputs
#8,837,795
of 26,245,199 outputs
Outputs from Pediatric Neurosurgery
#61
of 407 outputs
Outputs of similar age
#13,172
of 39,924 outputs
Outputs of similar age from Pediatric Neurosurgery
#1
of 4 outputs
Altmetric has tracked 26,245,199 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 407 research outputs from this source. They receive a mean Attention Score of 3.9. This one is in the 49th percentile – i.e., 49% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 39,924 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 10th percentile – i.e., 10% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 4 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
