RESUMEN
Objective:To investigate the current status of early nutritional support treatment in patients with severe acute pancreatitis complicated with intestinal fistula,and analyze the impact on the clinical outcomes of patients.Methods:Retrospective analysis was used to select the relevant data of 60 ICU admission patients with severe acute pancreatitis complicated with intestinal fistula of a tertiary hospital in Nanjing from May 2022 to May 2023,the statistics analysis of the patients'early nutritional support treatment were carried out,and explored the impact on clinical outcomes of patients.Results:A total of 45(75％)and 57(95％)patients started EN and PN treatment within 48 h of admission.The EEN calorie compliance rate after admission of 1 week was 44.2％.There was a difference in mechanical ventilation time and hospitalization expenses between the early enteral nutrition calorie group and non-compliance group,but no significant difference in the length of ICU stay(P＞0.005).Conclusion:The early enteral nutrition compliance rate of patients with severe acute pancreatitis combined with intestinal fistula is slightly lower.Compared with the early enteral nutrition non-compliance group,the enteral nutrition standard group has shorter mechanical ventilation time and lower total hospitalization costs,which can improve the clinical outcome of patients.
RESUMEN
<p><b>BACKGROUND</b>Noninvasive detection of vulnerable plaque has a significant implication for prevention and treatment of atherosclerotic diseases. The aim of this study is to investigate the difference between vulnerable plaques and stable plaques in magnetic resonance (MR) images.</p><p><b>METHODS</b>Atherosclerosis was induced in twenty male New Zealand white rabbits by high cholesterol diet and balloon injury of the abdominal aorta. After baseline (pre-triggering) MR imaging (MRI) scan, the rabbits underwent pharmaceutical triggering with Russell's viper venom and histamine to induce atherothrombosis, followed by another MRI scan 48 hours later (post-triggering). Rabbits were euthanized to obtain pathological and histological data. The results of MRI were compared with those of pathology and histology.</p><p><b>RESULTS</b>MRI showed that abdominal aorta of the rabbits had pathological change of atherosclerosis in different degrees. Seventy-five plaques were analysed, among which 14 had vulnerable thrombi and 61 stable. Thrombosis was identified in 7 of 11 rabbits by post-triggering MRI, the sensitivity and K value of MR in detection of vulnerable plaque was 71% and 0.803 (P < 0.05). MRI data significantly correlated with the histopathological data in fibrous cap thickness (r = 0.749) plaque area (r = 0.853), lipid core area (r = 0.900). Compared with stable plaques, vulnerable plaques had a significantly thinner fibrous cap ((0.58 ± 0.27) mm vs. (0.95 ± 0.22) mm), larger lipid core area ((7.56 ± 2.78) mm(2) vs. (3.29 ± 1.75) mm(2)), and a higher ratio of lipid core area/plaque area ((55 ± 16)% vs. (27 ± 17)%), but plaque area was comparable in two groups on MRI. The ratio of lipid core area/plaque area was a strong predictor of vulnerable plaques.</p><p><b>CONCLUSION</b>MRI could distinguish vulnerable plaques from stable plaques in a rabbit model of atherothrombosis and may thus be useful as a noninvasive modality for detection of vulnerable plaques in humans.</p>
