However, the time from exposure to presentation was unknown for a large majority of cases (52.1%).
Radiotherapy leads to increased exposure and presentation of tumor antigens, which triggers inflammatory cytokine signaling and immune cell recruitment.
Finally we have no indicator of duration of infection for those individuals who are currently seropositive for either infectious agent which might affect the observed association if a long lag time is required between exposure and presentation of symptoms.
Although a sizable proportion of the infected HCWs in the study were aware of the time and incident that resulted in their exposure, late presentation of infected HCWs to treatment facilities was a major issue.
Without understanding student exposure to presentations and procedures in the clinical environment, we cannot assure that they receive proper training in the clerkships [5], neither can we modify the curriculum to fit their needs.
Previous studies of patients with acquired prosopagnosia have shown a more pronounced deficit after limiting exposure to "tachystocopic" presentation [46] - anecdotal evidence only, or to presentations of 1500 or 5000ms [40].
In this study, we utilized two approaches for exposure-response modeling: quintile presentation of the exposure and continuous presentation of the exposure fitting semi-parametric models.
The mean time of exposure to ED presentation was 3.3 h.
The mean time from exposure to ED presentation for accidental cases was 2.4 h and for non-accidental cases was 4.2 h with an average mean time of 3.3 h for all cases.
We demonstrate that genetic susceptibility to the development of allergen-induced AHR is the result of a pulmonary environment which, following allergen exposure, allows allergen presentation by mDCs expressing high levels of co-stimulatory molecules, and producing a Th17-promoting cytokine profile (IL-23 and IL-6).
