One hundred and eighty two SD rats were randomly divided into the normal control group, fast operating group and food intake operating group. The experimental model of acute pancreatitis (AP) in rats was established by injecting 5 % sodium taurocholate into the pancreatic duct of rat according to Aho's method. The sandostatin was used for positive contrast. The concentrations of serum amylase, calcium, C reaction protein (CRP) and interleukin 6 (IL 6) were assayed respectively at different time points. The pathological sections were observed. Each operating group contained 10 rats. The mortality of the operating groups was observed during the 24 h. The serum amylase level in the AP rats was reduced after receiving vagotomy (VG, P <0.05). Although the serum calcium level in most groups was decreased, the reduction in the group with VG plus sandostatin was not obvious ( P >0.05). The increase of CRP and IL 6 was not obvious after VG ( P >0.05). The change of mortality was not significant ( P >0.05). The pathological sections showed that the AP pathological change was mild after VG. The disease condition of food intake operating group was more serious than that of fast operating group. It was suggested that VG had some influence on the prognosis of AP in rats. 展开更多

Background:Early systemic anticoagulation(SAC)is a common practice in acute necrotizing pancreatitis(ANP),and its impact on in-hospital clinical outcomes had been assessed.However,whether it affects long-term outcomes is unknown.This study aimed to evaluate the effect of SAC on 90-day readmission and other long-term outcomes in ANP patients.Methods:During January 2013 and December 2018,ANP patients admitted within 7 days from the onset of abdominal pain were screened.The primary outcome was 90-day readmission after discharge.Cox proportional-hazards regression model and mediation analysis were used to define the relationship between early SAC and 90-day readmission.Results:A total of 241 ANP patients were enrolled,of whom 143 received early SAC during their hospitalization and 98 did not.Patients who received early SAC experienced a lower incidence of splanchnic venous thrombosis(SVT)[risk ratio(RR)=0.40,95%CI:0.26-0.60,P<0.01]and lower 90-day readmission with an RR of 0.61(95%CI:0.41-0.91,P=0.02)than those who did not.For the quality of life,patients who received early SAC had a significantly higher score in the subscale of vitality(P=0.03)while the other subscales were all comparable between the two groups.Multivariable Cox regression model showed that early SAC was an independent protective factor for 90-day readmission after adjusting for potential confounders with a hazard ratio of 0.57(95%CI:0.34-0.96,P=0.04).Mediation analysis showed that SVT mediated 37.0%of the early SAC-90-day readmission causality.Conclusions:The application of early SAC may reduce the risk of 90-day readmission in the survivors of ANP patients,and reduced SVT incidence might be the primary contributor. 展开更多

Acute pancreatitis is a common systemic inflammatory disease, manifested by a spectrum of severity, ranging from mild in the majority of patients to severe acute pancreatitis. Patients with severe acute pancreatitis suffer from severe local and systemic complications and organ failure, leading to a poor prognosis. The early recognition of the severe condition is important to improve prognosis. Obesity has risen in tandem with an increase in the severity of acute pancreatitis in recent years. Studies have revealed that adipose tissue, particularly visceral adipose tissue is associated with the prognosis of acute pancreatitis. This review discussed the role of visceral adipose tissue in obese patients with acute pancreatitis and explored the possible mechanism involved. 展开更多

BACKGROUND Acute pancreatitis(AP)encompasses a spectrum of pancreatic inflammatory conditions,ranging from mild inflammation to severe pancreatic necrosis and multisystem organ failure.Given the challenges associated with obtaining human pancreatic samples,research on AP predominantly relies on animal models.In this study,we aimed to elucidate the fundamental molecular mechanisms underlying AP using various AP models.AIM To investigate the shared molecular changes underlying the development of AP across varying severity levels.METHODS AP was induced in animal models through treatment with caerulein alone or in combination with lipopolysaccharide(LPS).Additionally,using Ptf1αto drive the specific expression of the hM3 promoter in pancreatic acinar cells transgenic C57BL/6J-hM3/Ptf1α(cre)mice were administered Clozapine N-oxide to induce AP.Subsequently,we conducted RNA sequencing of pancreatic tissues and validated the expression of significantly different genes using the Gene Expression Omnibus(GEO)database.RESULTS Caerulein-induced AP showed severe inflammation and edema,which were exacerbated when combined with LPS and accompanied by partial pancreatic tissue necrosis.Compared with the control group,RNA sequencing analysis revealed 880 significantly differentially expressed genes in the caerulein model and 885 in the caerulein combined with the LPS model.Kyoto Encyclopedia of Genes and Genomes enrichment analysis and Gene Set Enrichment Analysis indicated substantial enrichment of the TLR and NOD-like receptor signaling pathway,TLR signaling pathway,and NF-κB signaling pathway,alongside elevated levels of apoptosis-related pathways,such as apoptosis,P53 pathway,and phagosome pathway.The significantly elevated genes in the TLR and NOD-like receptor signaling pathways,as well as in the apoptosis pathway,were validated through quantitative real-time PCR experiments in animal models.Validation from the GEO database revealed that only MYD88 concurred in both mouse pancreatic tissue and human AP peripheral blood,while TLR1,TLR7,RIPK3,and OAS2 genes exhibited marked elevation in human AP.The genes TUBA1A and GADD45A played significant roles in apoptosis within human AP.The transgenic mouse model hM3/Ptf1α(cre)successfully validated significant differential genes in the TLR and NOD-like receptor signaling pathways as well as the apoptosis pathway,indicating that these pathways represent shared pathological processes in AP across different models.CONCLUSION The TLR and NOD receptor signaling pathways play crucial roles in the inflammatory progression of AP,notably the MYD88 gene.Apoptosis holds a central position in the necrotic processes of AP,with TUBA1A and GADD45A genes exhibiting prominence in human AP. 展开更多

BACKGROUND Primary hyperparathyroidism(PHPT)-induced acute pancreatitis(AP)during pregnancy has rarely been described.Due to this rarity,there are no diagnostic or treatment algorithms for pregnant patients.AIM To determine appropriate diagnostic methods,therapeutic options,and factors related to maternal and fetal outcomes for PHPT-induced AP in pregnancy.METHODS A literature search of articles in English,Japanese,German,Spanish,and Italian was performed using PubMed(1946-2023),PubMed Central(1900-2023),and Google Scholar.The Preferred Reporting Items for Systematic reviews and Meta-Analyses(PRISMA)protocol was followed.The search terms included“pancreatite acuta,”“iperparatiroidismo primario,”“gravidanza,”“travaglio,”“puerperio,”“postpartum,”“akute pankreatitis,”“primärer hyperparathyreoidismus,”“Schwangerschaft,”“Wehen,”“Wochenbett,”“pancreatitis aguda,”“hiperparatiroidismo primario,”“embarazo,”“parto,”“puerperio,”“posparto,”“acute pancreatitis,”“primary hyperparathyroidism,”“pregnancy,”“labor,”“puerperium,”and“postpartum.”Additional studies were identified by reviewing the reference lists of retrieved studies.Demographic,imaging,surgical,obstetric,and outcome data were obtained.RESULTS Fifty-four cases were collected from the 51 studies.The median maternal age was 29 years.PHPT-induced AP starts at the 20th gestational week;higher gestational weeks were seen in mothers who died(mean gestational week 28).Median values of amylase(1399,Q1-Q3=519-2072),lipase(2072,Q1-Q3=893-2804),serum calcium(3.5,Q1-Q3=3.1-3.9),and parathormone(PTH)(384,Q1-Q3=123-910)were reported.In 46 cases,adenoma was the cause of PHPT,followed by 2 cases of carcinoma and 1 case of hyperplasia.In the remaining 5 cases,the diagnosis was not reported.Neck ultrasound was positive in 34 cases,whereas sestamibi was performed in 3 cases,and neck computed tomography or magnetic resonance imaging was performed in 9 cases(the enlarged parathyroid gland was not localized in 3 cases).Surgery was the preferred treatment during pregnancy in 33 cases(median week of gestation 25,Q1-Q3=20-30)and postpartum in 12 cases.The timing was not reported in the remaining 9 cases,or surgery was not performed.AP was managed surgically in 11 cases and conservatively in 43(79.6%)cases.Maternal and fetal mortality was 9.3%(5 cases).Surgery was more common in deceased mothers(60.0%vs 16.3%;P=0.052),and PTH values tended to be higher in this group(910 pg/mL vs 302 pg/mL;P=0.059).Maternal mortality was higher with higher serum lipase levels and earlier delivery week.Higher calcium(4.1 mmol/L vs 3.3 mmol/L;P=0.009)and PTH(1914 pg/mL vs 302 pg/mL;P=0.003)values increased fetal/child mortality,as well as abortions(40.0%vs 0.0%;P=0.007)and complex deliveries(60.0%vs 8.2%;P=0.01).CONCLUSION If serum calcium is not tested during admission,definitive diagnosis of PHPT-induced AP in pregnancy is delayed,while early diagnosis and immediate intervention lead to excellent maternal and fetal outcomes. 展开更多

Background:Visceral adipose tissue(VAT)has been linked to the severe acute pancreatitis(SAP)prognosis,although the underlying mechanism remains unclear.It has been reported that pyroptosis worsens SAP.The present study aimed to verify whether mesenteric adipose tissue(MAT,a component of VAT)can cause secondary intestinal injury through the pyroptotic pathway.Methods:Thirty-six male Sprague Dawley(SD)rats were divided into six different groups.Twelve rats were randomly divided into the SAP and control groups.We monitored the changes of MAT and B lymphocytes infiltration in MAT of SAP rats.Twelve SAP rats were injected with MAT B lymphocytes or phosphate buffer solution(PBS).The remaining twelve SAP rats were first injected with MAT B lymphocytes,and then with MCC950(NLRP3 inhibitor)or PBS.We collected blood and tissue samples from pancreas,gut and MAT for analysis.Results:Compared to the control rats,the SAP group showed inflammation in MAT,including higher expression of tumor necrosis factor(TNF-α)and interleukin-6(IL-6),lower expression of IL-10,and histological changes.Flow cytometry analysis revealed B lymphocytes infiltration in MAT but not T lymphocytes and macrophages.The SAP rats also exhibited intestinal injury,characterized by lower expression of zonula occludens-1(ZO-1)and occludin,higher levels of lipopolysaccharide and diamine oxidase,and pathological changes.The expression of NLRP3 and n-GSDMD,which are responsible for pyroptosis,was increased in the intestine of SAP rats.The injection of MAT B lymphocytes into SAP rats exacerbated the inflammation in MAT.The upregulation of pyroptosis reduced tight junction in the intestine,which contributed to the SAP progression,including higher inflammatory indicators and worse histological changes.The administration of MCC950 to SAP+MAT B rats downregulated pyroptosis,which subsequently improved the intestinal barrier and ameliorated inflammatory response of SAP.Conclusions:In SAP,MAT B lymphocytes aggravated local inflammation,and promoted the injury to the intestine through the enteric pyroptotic pathway. 展开更多

BACKGROUND The incidence of hypertriglyceridemia(HTG)-induced acute pancreatitis(AP)is steadily increasing in China,becoming the second leading cause of AP.Clinical complications and outcomes associated with HTG-AP are generally more severe than those seen in AP caused by other etiologies.HTG-AP is closely linked to metabolic dysfunction and frequently coexists with metabolic syndrome or its components.However,the impact of metabolic syndrome components on HTGAP clinical outcomes remains unclear.AIM To investigate the impact of metabolic syndrome component burden on clinical outcomes in HTG-AP.METHODS In this retrospective study of 255 patients diagnosed with HTG-AP at the First Affiliated Hospital of Guangxi Medical University,we collected data on patient demographics,clinical scores,complications,and clinical outcomes.Subsequently,we analyzed the influence of the presence and number of individual metabolic syndrome components,including obesity,hyperglycemia,hypertension,and low high-density lipoprotein cholesterol(HDL-C),on the aforementioned parameters in HTG-AP patients.RESULTS This study found that metabolic syndrome components were associated with an increased risk of various complications in HTG-AP,with low HDL-C being the most significant risk factor for clinical outcomes.The risk of complications increased with the number of metabolic syndrome components.Adjusted for age and sex,patients with highcomponent metabolic syndrome had significantly higher risks of renal failure[odds ratio(OR)=3.02,95%CI:1.12-8.11)],SAP(OR=5.05,95%CI:2.04-12.49),and intensive care unit admission(OR=6.41,95%CI:2.42-16.97)compared to those without metabolic syndrome.CONCLUSION The coexistence of multiple metabolic syndrome components can synergistically worsen the clinical course of HTGAP,making it crucial to monitor these components for effective disease management. 展开更多

BACKGROUND Increasing evidence has demonstrated that N6-methyladenosine(m6A)RNA modification plays an essential role in a wide range of pathological conditions.Impaired autophagy is a critical hallmark of acute pancreatitis(AP).AIM To explore the role of the m6A modification of ZKSCAN3 in the regulation of autophagy in AP.METHODS The AP mouse cell model was established by cerulein-treated mouse pancreatic acinar cells(MPC-83),and the results were confirmed by the levels of amylase and inflammatory factors.Autophagy activity was evaluated by specific identification of the autophagy-related microstructure and the expression of autophagy-related genes.ZKSCAN3 and ALKBH5 were knocked down to study the function in AP.A m6A RNA binding protein immunoprecipitation assay was used to study how the m6A modification of ZKSCAN3 mRNA is regulated by ALKBH.RESULTS The increased expression of amylase and inflammatory factors in the supernatant and the accumulation of autophagic vacuoles verified that the AP mouse cell model was established.The downregulation of LAMP2 and upregulation of LC3-II/I and SQSTM1 demonstrated that autophagy was impaired in AP.The expression of ZKSCAN3 was upregulated in AP.Inhibition of ZKSCAN3 increased the expression of LAMP2 and decreased the expression of the inflammatory factors,LC3-II/I and SQSTM1.Furthermore,ALKBH5 was upregulated in AP.Knockdown of ALKBH5 downregulated ZKSCAN3 expression and restored decreased autophagic flux in AP.Notably,the bioinformatic analysis revealed 23 potential m6A modification sites on ZKSCAN3 mRNA.The m6A modification of ZKSCAN3 mRNA was significantly decreased in AP.Knockdown of ALKBH5 increased the modification of ZKSCAN3 mRNA,which confirmed that ALKBH5 upregulated ZKSCAN3 expression in a m6A-dependent manner.CONCLUSION ALKBH5 inhibits autophagic flux through m6A demethylation of ZKSCAN3 mRNA in AP,thereby aggravating the severity of the disease. 展开更多

Background:Acute pancreatitis(AP),known for its rapid onset and significant incidence and mortality rates,presents a clinical challenge due to the limited availability of effective treatments and preventive measures.Anemarsaponin B(ASB)has emerged as a potential therapeutic agent,demonstrating capabilities in reducing immune inflammation,positioning it as a promising candidate for AP treatment.Methods:We investigated the effects of ASB on AP in mice,induced by caerulein and lipopolysaccharide(LPS).Peripheral blood samples were collected 24 h post-induction with caerulein to assess of key biomarkers including lipase,amylase,TNF-α,IL-1β,IL-6,SOD,and GSH-Px.A range of techniques such as immunohistochemistry staining,immunofluorescence staining,Western blotting,and quantitative Polymerase Chain Reaction(q-PCR),were employed to measure the expression of critical genes.Additionally,pancreas samples from the mice were harvested for microbiome and metabolome sequencing,with the data analyzed to understand the impact of ASB on AP.Results:Our study revealed that,compared to the sham group,the AP group exhibited significantly higher serum levels of lipase,amylase,and cytokines,while levels of SOD and GSH Px were notably lower.Treatment with ASB led to a substantial decrease in the levels of lipase,amylase,and cytokines,and an increase in SOD and GSH-Px levels.q-PCR analysis of pancreatic histiocytes corroborated these serum findings.Hematoxylin and Eosin(H&E)staining indicated significant alterations in the pathological changes in the pancreas,lungs,and small intestine of the AP model due to ASB.Immunofluorescence assays demonstrated that ASB alleviated the apoptosis of pancreatic histiocytes in the AP model.Western Blot and histological analyses showed that ASB reduced the phosphorylation of TAK,p38,JNK,and ERK proteins,as well as the levels of TRAF6 protein in the AP model.Furthermore,metabolomic and gut microbiota analysis identified 27 differential metabolites and 34 differential species.The combined metabolome and microbiome analysis suggested an association between certain microbes(e.g.,unclassified-Saprospiraceae and unclassified-Micavibrionales)and metabolites(e.g.,LysoPE(0:0/20:0),PC(DiMe(13,5)/PGJ2)),and Heptanoic acid,indicating potential pathways through which ASB may exert its therapeutic effects in AP.Conclusions:ASB exhibits therapeutic efficacy in treating AP induced by caerulein combined with lipopolysaccharide(LPS),primarily through modulating the mitogenactivated protein kinase(MAPK)signaling pathway.This discovery offers fresh perspectives for AP drug development,underscoring the potential of targeting specific cellular pathways.Additionally,the intricate interplay observed between the gut microbiota and metabolites following ASB treatment highlights novel therapeutic targets,suggesting that manipulating the gut microbiome and metabolome could be a viable strategy in AP management.These findings pave the way for further research into comprehensive treatment approaches that incorporate both pharmacological intervention and microbiota modulation. 展开更多

BACKGROUND Liver injury is common in severe acute pancreatitis(SAP).Excessive autophagy often leads to an imbalance of homeostasis in hepatocytes,which induces lipid peroxidation and mitochondrial iron deposition and ultimately leads to ferroptosis.Our previous study found that milk fat globule epidermal growth factor 8(MFG-E8)alleviates acinar cell damage during SAP via binding toαvβ3/5 integrins.MFG-E8 also seems to mitigate pancreatic fibrosis via inhibiting chaperone-mediated autophagy.AIM To speculate whether MFG-E8 could also alleviate SAP induced liver injury by restoring the abnormal autophagy flux.METHODS SAP was induced in mice by 2 hly intraperitoneal injections of 4.0 g/kg L-arginine or 7 hly injections of 50μg/kg cerulein plus lipopolysaccharide.mfge8-knockout mice were used to study the effect of MFG-E8 deficiency on SAPinduced liver injury.Cilengitide,a specificαvβ3/5 integrin inhibitor,was used to investigate the possible mechanism of MFG-E8.RESULTS The results showed that MFG-E8 deficiency aggravated SAP-induced liver injury in mice,enhanced autophagy flux in hepatocyte,and worsened the degree of ferroptosis.Exogenous MFG-E8 reduced SAP-induced liver injury in a dose-dependent manner.Mechanistically,MFG-E8 mitigated excessive autophagy and inhibited ferroptosis in liver cells.Cilengitide abolished MFG-E8’s beneficial effects in SAP-induced liver injury.CONCLUSION MFG-E8 acts as an endogenous protective mediator in SAP-induced liver injury.MFG-E8 alleviates the excessive autophagy and inhibits ferroptosis in hepatocytes by binding to integrinαVβ3/5. 展开更多

Hypertriglyceridemia is the third leading cause of acute pancreatitis(AP),and its incidence is increasing.Due to its relatively insidious etiology,it is easy to be ignored in the early stages.In China,Chaiqin Chengqi Decoction(CQCQD)has long been employed for treating AP.AIM To evaluate the effectiveness of CQCQD in patients diagnosed with mild/moderately severe hypertriglyceridemic AP(HTG-AP).METHODS In this study,the clinical data of 39 patients with HTG-AP admitted from January 2019 to November 2022 were collected.The changes of blood lipids,gastrointestinal symptoms,and abdominal pain before and after treatment were analyzed and compared between the two groups.RESULTS Twenty patients were treated with the conventional HTG-AP regimen,and 19 patients were additionally treated with CQCQD.After receiving treatment,the triglycerides(TG)level of the CQCQD group was lower than that of the CQCQD group(3.14±0.25 mmol/L vs 4.96±0.47 mmol/L,P<0.01).After 3 d of treatment,the patients in the CQCQD group had more bowel movements than the control group(2.51±0.25 times vs 1.00±0.17 times,P=0.01).The gastrointestinal function of most patients returned to normal,and the acute gastrointestinal injury score was significantly lower than that of the control group(0.11±0.07 vs 0.42±0.11,P<0.01).CONCLUSION In patients with HTG-AP,CQCQD can significantly reduce the TG level,shorten the recovery time of defecation,significantly improve the gastrointestinal function. 展开更多

BACKGROUND Acute pancreatitis in pregnancy(APIP)is a rare and serious condition,and severe APIP(SAPIP)can lead to pancreatic necrosis,abscess,multiple organ dysfunction,and other adverse maternal and infant outcomes.Therefore,early identification or prediction of SAPIP is important.AIM To assess factors for early identification or prediction of SAPIP.METHODS The clinical data of patients with APIP were retrospectively analyzed.Patients were classified with mild acute pancreatitis or severe acute pancreatitis,and the clinical characteristics and laboratory biochemical indexes were compared between the two groups.Logical regression and receiver operating characteristic curve analyses were performed to assess the efficacy of the factors for identification or prediction of SAPIP.RESULTS A total of 45 APIP patients were enrolled.Compared with the mild acute pancreatitis group,the severe acute pancreatitis group had significantly increased(P<0.01)heart rate(HR),hemoglobin,neutrophil ratio(NEUT%),and neutrophil–lymphocyte ratio(NLR),while lymphocytes were significantly decreased(P<0.01).Logical regression analysis showed that HR,NEUT%,NLR,and lymphocyte count differed significantly(P<0.01)between the groups.These may be factors for early identification or prediction of SAPIP.The area under the curve of HR,NEUT%,NLR,and lymphocyte count in the receiver operating characteristic curve analysis was 0.748,0.732,0.821,and 0.774,respectively.The combined analysis showed that the area under the curve,sensitivity,and specificity were 0.869,90.5%,and 70.8%,respectively.CONCLUSION HR,NEUT%,NLR,and lymphocyte count can be used for early identification or prediction of SAPIP,and the combination of the four factors is expected to improve identification or prediction of SAPIP. 展开更多

BACKGROUND The neutrophil-to-lymphocyte ratio(NLR)and platelet-to-lymphocyte ratio(PLR)are novel inflammatory indicators that can be used to predict the severity and prognosis of various diseases.We categorize acute pancreatitis by etiology into acute biliary pancreatitis(ABP)and hypertriglyceridemia-induced acute pancreatitis(HTGP).AIM To investigate the clinical significance of NLR and PLR in assessing persistent organ failure(POF)in HTGP and ABP.METHODS A total of 1450 patients diagnosed with acute pancreatitis(AP)for the first time at Shanxi Bethune Hospital between January 2012 and January 2023 were enrolled.The patients were categorized into two groups according to the etiology of AP:ABP in 530 patients and HTGP in 241 patients.We collected and compared the clinical data of the patients,including NLR,PLR,and AP prognostic scoring systems,within 48 h of hospital admission.RESULTS The NLR(9.1 vs 6.9,P<0.001)and PLR(203.1 vs 160.5,P<0.001)were significantly higher in the ABP group than in the HTGP group.In the HTGP group,both NLR and PLR were significantly increased in patients with severe AP and those with a SOFA score≥3.Likewise,in the ABP group,NLR and PLR were significantly elevated in patients with severe AP,modified computed tomography severity index score≥4,Japanese Severity Score≥3,and modified Marshall score≥2.Moreover,NLR and PLR showed predictive value for the development of POF in both the ABP and HTGP groups.CONCLUSION NLR and PLR vary between ABP and HTGP,are strongly associated with AP prognostic scoring systems,and have predictive potential for the occurrence of POF in both ABP and HTGP. 展开更多

BACKGROUND Acute pancreatitis(AP)is a disease caused by abnormal activation of pancreatic enzymes and can lead to self-digestion of pancreatic tissues and dysfunction of other organs.Enteral nutrition plays a vital role in the treatment of AP because it can meet the nutritional needs of patients,promote the recovery of intestinal function,and maintain the barrier and immune functions of the intestine.However,the risk of aspiration during enteral nutrition is high;once aspiration occurs,it may cause serious complications,such as aspiration pneumonia,and suffocation,posing a threat to the patient’s life.This study aims to establish and validate a prediction model for enteral nutrition aspiration during hospitalization in patients with AP.AIM To establish and validate a predictive model for enteral nutrition aspiration during hospitalization in patients with AP.METHODS A retrospective review was conducted on 200 patients with AP admitted to Chengdu Shangjin Nanfu Hospital,West China Hospital of Sichuan University from January 2020 to February 2024.Clinical data were collected from the electronic medical record system.Patients were randomly divided into a validation group(n=40)and a modeling group(n=160)in a 1:4 ratio,matched with 200 patients from the same time period.The modeling group was further categorized into an aspiration group(n=25)and a non-aspiration group(n=175)based on the occurrence of enteral nutrition aspiration during hospitalization.Univariate and multivariate logistic regression analyses were performed to identify factors influencing enteral nutrition aspiration in patients with AP during hospitalization.A prediction model for enteral nutrition aspiration during hospitalization was constructed,and calibration curves were used for validation.Receiver operating characteristic curve analysis was conducted to evaluate the predictive value of the model.RESULTS There was no statistically significant difference in general data between the validation and modeling groups(P>0.05).The comparison of age,gender,body mass index,smoking history,hypertension history,and diabetes history showed no statistically significant difference between the two groups(P>0.05).However,patient position,consciousness status,nutritional risk,Acute Physiology and Chronic Health Evaluation(APACHE-II)score,and length of nasogastric tube placement showed statistically significant differences(P<0.05)between the two groups.Multivariate logistic regression analysis showed that patient position,consciousness status,nutritional risk,APACHE-II score,and length of nasogastric tube placement were independent factors influencing enteral nutrition aspiration in patients with AP during hospitalization(P<0.05).These factors were incorporated into the prediction model,which showed good consistency between the predicted and actual risks,as indicated by calibration curves with slopes close to 1 in the training and validation sets.Receiver operating characteristic analysis revealed an area under the curve(AUC)of 0.926(95%CI:0.8889-0.9675)in the training set.The optimal cutoff value is 0.73,with a sensitivity of 88.4 and specificity of 85.2.In the validation set,the AUC of the model for predicting enteral nutrition aspiration in patients with AP patients during hospitalization was 0.902,with a standard error of 0.040(95%CI:0.8284-0.9858),and the best cutoff value was 0.73,with a sensitivity of 91.9 and specificity of 81.8.CONCLUSION A prediction model for enteral nutrition aspiration during hospitalization in patients with AP was established and demonstrated high predictive value.Further clinical application of the model is warranted. 展开更多

We suggest that during severe acute pancreatitis(SAP)with intra-abdominal hypertension,practitioners should consider decompressive laparotomy,even with intra-abdominal pressure(IAP)below 25 mmHg.Indeed,in this setting,non-occlusive mesenteric ischemia(NOMI)may occur even with IAP below this cutoff and lead to transmural necrosis if abdominal perfusion pressure is not promptly restored.We report our experience of 18 critically ill patients with SAP having undergone decompressive laparotomy of which one third had NOMI while IAP was mostly below 25 mmHg. 展开更多
