In the stallion these teeth are arranged as follows on the upper and lower jaws: 12 incisors that cut and pull at grasses; 4 canines, remnants without function in the modern horse and usually not found in mares; 12 premolars and 12 molars, high prisms that continue to grow out of the jaw in order to replace the surfaces worn off in grinding food.
Because males had higher PRISM scores but no increased CFR, we analyzed the different variables determining the PRISM score.
Male patients had significantly fewer PICU-free days (p = 0.04) and higher PRISM scores (p = 0.02) than females.
Patients in the sepsis cohort were younger and had a higher PRISM score compared with patients in the SIRS cohort.
Neonates were more frequently ventilated and had a higher PRISM (pediatric risk of mortality) score than older children.
Only 2 patients in the TBI group died, both having suffered multiple injuries from motor vehicle accidents (patients with the highest PRISM and TISS).
This indicates that younger children had higher PRISM scores, higher PDR, more presence of DIC, lower base excess, lower CRP, lower fibrinogen, lower leukocyte count, lower thrombocyte count, and lower glucose levels on admission.
In multivariate analysis, independent statistically significant risk factors for developing AKI were higher PRISM score, need for mechanical ventilation, documented infection, bSCr measured and not being a postoperative patient (odds ratios shown in Table 1).
We found higher C-peptide levels in more severely ill patients (higher PRISM, PIM2, and PELOD scores) and that higher C-peptide levels were associated with a longer PICU stay, probably because C-peptide levels were a marker of more severe ill.
Nonetheless, patients in the former group were more severely ill on admission, as reflected by a significantly higher PRISM II score (48.9 (IQR, 25.5 to 77.1)) than that assigned to non-AKI patients (25.1 (IQR, 10.10 to 54.1) (P <0.001 by Mann–Whitney U test).
