Hypoxic-Ischemic Encephalopathy-Associated Liver Fatty Degeneration and the Effects of Therapeutic Hypothermia in Newborn Piglets
Bibliographic record
Abstract
BACKGROUND: Although liver can be injured under the hypoxic-ischemic encephalopathy (HIE) condition, there is currently no histopathological evidence. Therapeutic hypothermia is used to protect the brain; however, the therapeutic potential for concomitant liver injury is unknown. OBJECTIVES: This study aimed to histopathologically prove HIE-associated liver injury and to investigate the influence of therapeutic hypothermia in a newborn piglet HIE model. METHODS: Eighteen newborn piglets were divided into 3 groups: control (n = 4), HIE (n = 8), and therapeutic hypothermia (n = 6) groups. The hypoxic insult was induced by decreasing the fraction of inspiratory oxygen from 21 to 2-4% over 40 min while monitoring cerebral blood volume and cerebral hemoglobin oxygen saturation. For therapeutic hypothermia, whole-body cooling at 33-34°C was administered for 24 h after the hypoxic insult. We hematologically and histopathologically investigated the liver injury in all groups. RESULTS: Alanine transaminase and lactate dehydrogenase levels in the HIE group were significantly elevated compared with those in the control group. Micro-lipid droplet accumulation in the periportal zone, but not in the perivenous zone, was significantly greater in the HIE group than in the control group and significantly smaller in the therapeutic hypothermia group than in the HIE group. CONCLUSIONS: We demonstrated that micro-lipid droplet accumulation in the cytoplasm of hepatocytes in the periportal zone occurs under the HIE condition and that this accumulation is suppressed by therapeutic hypothermia.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
