Optimizing nutrition in hepatic cirrhosis: A comprehensive assessment and care approach.

Cirrhosis is considered a growing cause of morbidity and mortality, which represents a significant public health problem. Currently, there is no effective treatment to reverse cirrhosis. Treatment primarily centers on addressing the underlying liver condition, monitoring, and managing portal hypertension-related complications, and evaluating the potential for liver transplantation in cases of decompensated cirrhosis, marked by rapid progression and the emergence of complications like variceal bleeding, hepatic encephalopathy, ascites, malnutrition, and more. Malnutrition, a prevalent complication across all disease stages, is often underdiagnosed in cirrhosis due to the complexities of nutritional assessment in patients with fluid retention and/or obesity, despite its crucial impact on prognosis. Increasing emphasis has been placed on the collaboration of nutritionists within hepatology and Liver transplant teams to deliver comprehensive care, a practice that has shown to improve outcomes. This review covers appropriate screening and assessment methods for evaluating the nutritional status of this population, diagnostic approaches for malnutrition, and context-specific nutrition treatments. It also discusses evidence-based recommendations for supplementation and physical exercise, both essential elements of the standard care provided to cirrhotic patients.

A reliable scoring system after major liver resection in mice.

BACKGROUND: Posthepatectomy liver failure and its transplant counterpart, small-for-size syndrome, remain significant limitations for liver resections and segmental liver transplantation. Partial hepatectomy in mice is one of the most commonly used models to study liver regeneration, but blood and tissue sampling necessary to collect data can affect outcomes or even require euthanasia. We therefore developed a quantitative observational system to predict death from hepatectomy during the first 24 postoperative hours. MATERIALS AND METHODS: A total of 100 female, 10 to 12-week-old C57BL/6 mice underwent two-thirds hepatectomy and were monitored for up to 7 d. Our scoring system was based on five categories, each assigned 0-2 points: activity level, body posture, fur condition, respiratory status, and eye appearance. Seventy-five mice were scored 6 h, 12 h, 24 h, 2 d, 3 d, 5 d, and 7 d after surgery. The remaining 25 mice were scored similarly, but underwent, in addition, blood sampling for serum alanine aminotransferase, total bilirubin, interleukin-6, tumor necrosis factor-alpha, or euthanasia with liver sampling for conventional hematoxylin-eosin and Ki-67 staining. RESULTS: Retrospective analysis indicated that body condition scores ≤5 on two consecutive time points within the first 24 postoperative hours accurately predicted eventual death. Animals in the low scoring group also had significantly higher serum alanine aminotransferase, total bilirubin, interleukin-6, tumor necrosis factor-alpha, more hepatocyte necrosis in hematoxylin-eosin, and fewer Ki-67 positive hepatocytes. CONCLUSIONS: Our scoring system accurately predicts survival, hepatocyte damage, liver regeneration, and systemic inflammation in a mouse hepatectomy model, within the first 24 hours of surgery. This could be useful in evaluating posthepatectomy interventions for their effect on survival and liver regeneration.
