Findings demonstrate the impact of injury frequency and recovery time between mild head injuries on altering the trigeminal pain system; factors that are essential to consider when investigating the persistence of post-concussion headache in future pre-clinical and clinical research designs.
Long-term protection against meningococcal disease is associated with persistence of post-vaccination antibodies at protective levels.
Rumination about trauma predicts the persistence of post-traumatic stress disorder in prospective longitudinal studies from 6 months to 3 years later (e.g., Ehlers, Mayou & Bryant, 1998, 2003).
The persistence of post-concussive symptoms (PCS) beyond 3 months in sports-related mTBI is rare [ 9], but prevalence rates of persistent PCS have been as high as 15% in other civilian trauma victims [ 10].
Differences in the persistence of post-boost MenC bactericidal antibody are consistent with observations from other studies of the persistence of MenC bactericidal antibody after priming with different MenC glycoconjugates in infancy.
However, the results of our study indicate that administration of vaccine during treatment with ceftiofur hydrochloride can have a negative effect on the development and persistence of post-vaccinal humoral immunity against SIV and in this way affect the protection against infection.
Sera were collected at day 28 and day 112 after vaccination to examine the immediate response, and the longer term persistence of antibodies post vaccination.
Nevertheless, the use of pills that do not contain the active ingredient or insufficient doses, besides a delay in going to the hospital for fear of being denounced to the police, can contribute to the persistence of hemorrhagic post abortion complications and infections [ 28, 29].
Relapse post-transplant is due either to contamination of the stem cell harvest or persistence of MRD post-HDT.
The majority of the studies found in the literature analyze the most frequent post-operative symptoms during the first 24 hours after AS, and signal the persistence of severe post-operative pain in these patients as the main factor to control [ 1, 2].
