Abstract
The incidence and prevalence of obesity have been rising in the United States, negatively impacting the population's overall health. This study seeks to better understand the impact of obesity on patients presenting with acute alcoholic pancreatitis (AAP). Data collected using the National Inpatient Sample (NIS) from the fourth quarter of 2015 to 2019 with a principal diagnosis of AAP and secondary obesity were analyzed. Confounders were adjusted for multivariate regression analysis using a multitude of factors. A total of 229,510 patients were identified with a diagnosis of AAP, among which 14,150 were also identified as obese. A majority of the sample, both obese and non-obese patients with AAP, were middle-aged white females. The average comorbidity index (CCI) was lower in the non-obese cohort compared to the obese cohort. Compared to non-obese patients, patients with AAP who were obese had higher hospital charges and a longer LOS (p<0.05. Additionally, compared to non-obese patients, obese patients with AAP had higher odds of mortality and adverse events, such as acute renal failure and respiratory failure (p<0.05). Current research supports these complications, which have shown an association with increased visceral fat in or around the pancreas that can ultimately worsen acute pancreatitis outcomes and aggravate AAP by damaging the intestinal mucosal barrier. These findings should be considered when treating obese patients who develop AAP. Strategies to increase surveillance of such patients should be implemented to reduce complications and mortality in this population.

Abstract
Background Excess body weight (EBW) is a risk factor for various acute and chronic conditions. Conversely, the "obesity paradox" suggests a protective effect of higher body weight on some disease outcomes. This article discusses the role of EBW along the disease continuum of pancreatitis and pancreatic cancer (PC) in terms of incidence and outcome. Summary Comparison of findings is hampered by the use of different methods to assess EBW. Nevertheless, in acute pancreatitis (AP) and PC, EBW, especially visceral obesity, presents a distinct risk factor and predictor of a negative outcome. Findings of a protective effect likely result from nonconsideration of fat distribution or other confounders. Regarding chronic pancreatitis (CP), few studies indicate lower incidence and a better outcome with higher body mass. However, there is insufficient evidence to confirm the existence of an obesity paradox. The precise mechanisms of how EBW affects the disease continuum require further elucidation but both common and disease-specific effects seem involved. Key Messages EBW is associated with higher incidence and a negative outcome in AP and PC. The association with CP is less conclusive. Thus, maintaining normal weight is advisable at any stage of the disease continuum.

Abstract
Obesity sometimes seems protective in disease. This obesity paradox is predominantly described in reports from the Western Hemisphere during acute illnesses. Since adipose triglyceride composition corresponds to long-term dietary patterns, we performed a meta-analysis modeling the effect of obesity on severity of acute pancreatitis, in the context of dietary patterns of the countries from which the studies originated. Increased severity was noted in leaner populations with a higher proportion of unsaturated fat intake. In mice, greater hydrolysis of unsaturated visceral triglyceride caused worse organ failure during pancreatitis, even when the mice were leaner than those having saturated triglyceride. Saturation interfered with triglyceride's interaction and lipolysis by pancreatic triglyceride lipase, which mediates organ failure. Unsaturation increased fatty acid monomers in vivo and aqueous media, resulting in greater lipotoxic cellular responses and organ failure. Therefore, visceral triglyceride saturation reduces the ensuing lipotoxicity despite higher adiposity, thus explaining the obesity paradox.

Abstract
OBJECTIVES The incidence rates of acute pancreatitis (AP) and the prevalence of class III obesity, and metabolic syndrome (MetS) are increasing in the US. Since class III obesity was associated with adverse clinical outcomes of AP, we sought to understand if the presence of metabolic comorbidities collectively recognized, as MetS were associated with worse clinical outcomes and increased health-care utilization. METHODS The Nationwide Readmissions Database (NRD) (2010-2014) was reviewed to identify all adult subjects with a principal discharge diagnosis of AP. Inpatient mortality, severe AP (SAP), and 30-day readmissions were the primary outcomes analyzed. Propensity score weighted analyses were used to compare AP subjects with and without MetS and were further stratified by class III obesity status. RESULTS MetS was associated with 12.91% (139,165/1,078,183) of all admissions with AP. Propensity score weighted analyses showed that MetS was associated with an increased proportion of SAP (OR 1.21, 95% CI 1.17, 1.25), but decreased mortality (OR 0.62, 95% CI 0.54, 0.70) and 30-day readmissions (OR 0.86, 95% CI 0.83, 0.89). Propensity score weighted analyses also revealed that class III obesity was independently associated with increased mortality in AP subjects with (OR 1.92, 95% CI 1.41, 2.61) and without MetS (OR 1.55, 95% CI 1.26, 1.92), and increased SAP in subjects with and without MetS. CONCLUSIONS Class III obesity appears to be the primary factor associated with adverse clinical outcomes in subjects with MetS admitted with AP. This has significant implications for patient management and future research targeting AP.

Abstract
GOALS The aim of this study was to determine a potential strategy to prevent acute pancreatitis (AP) from deteriorating in obese patients. BACKGROUND Nutritional support plays a critical role in the treatment of AP. Early enteral nutrition (EEN) is considered to be able to protect mucosa of AP patients and alleviate inflammatory reactions. Obesity worsen AP prognosis. However, little is known about the effects of EEN in obese patients. STUDY Prospective randomized control trial. Subjects with moderately severe AP or severe AP were divided into the visceral fat obesity (VFO) group and the non-VFO group by obesity index VFO. The patients received "delayed" enteral nutrition (started enteral nutrition feeding after the first 48 hours after admission to the hospital: group A: patients of non-VFO, n=108; group B: VFO patients, n=88) or EEN (in the VFO subgroup, group C: n=91).Occurrence of complication, clinical outcomes, plasma levels of cytokines, and intestine gut barrier index were measured at different timepoints after admission. RESULTS VFO was a risk factor for aggravating of AP. EEN prevented the VFO patients from developing pancreatic necrotic infection, the mechanism of which might be related with inhibiting excessive inflammatory reactions, adjusting the imbalance of inflammatory response, and alleviating ischemia of intestine mucosa. CONCLUSIONS The potential strategy, EEN, was able to prevent AP from deteriorating in obese patients.

Abstract
BACKGROUND Computed tomography-measured visceral adipose tissue (VAT) and the distribution of VAT are highly correlated with the severity and prognosis of acute pancreatitis (AP). To date, all available data are from the overall AP patient population; no subgroup analysis has been conducted to evaluate patients with moderately severe AP or patients with hyperlipidemia acute pancreatitis (HLAP) as independent populations. Currently, studies on the relationship between VAT and HLAP are lacking. MATERIALS AND METHODS A total of 235 patients with moderately severe AP or severe acute pancreatitis were divided into 2 groups according to whether hyperlipidemia was present: the HLAP group and the non-HLAP group. The general inpatient information was collected, and computed tomography was used to measure VAT, subcutaneous adipose tissue (SAT), total adipose tissue, and VAT/SAT (V/S). The data were subjected to t test, χ test, matrix scatter plot, logistic regression, and receiver operating characteristic analyses to evaluate the relationship between VAT and HLAP severity. RESULTS Significant differences were observed in VAT, SAT, total adipose tissue, and triglycerides (TGs) between the HLAP group and the non-HLAP group (P<0.001). Significant correlations were observed between VAT and body mass index (r=0.425, P=0.017) and between VAT and TG (r=0.367, P=0.042). In the HLAP group, VAT, V/S, TG, and local complications may have significant effects on disease severity. The receiver operating characteristic curves showed that VAT and V/S were more reliable than TGs in evaluating disease severity [area under the curve (AUC) of VAT: 0.819, P<0.001; AUC of V/S: 0.855, P<0.001; AUC of TG: 0.671, P=0.04]. Disease severity was reliably evaluated at 139 cm, the cut-off value of VAT. The cut-off value of V/S was 1.145; high V/S was associated with extended intensive care unit stay. VAT and its distribution had no significant effects on mortality. CONCLUSIONS For patients with moderately severe to severe HLAP, VAT was correlated with body mass index and TG. VAT and V/S were valuable factors for evaluating disease severity and prognosis. However, VAT had no effect on mortality, and VAT could not be used to evaluate patients with moderately severe to severe non-HLAP.

Abstract
Acute lipolysis of visceral fat or circulating triglycerides may worsen acute pancreatitis (AP)-associated local and systemic injury. The pancreas expresses pancreatic triacylglycerol lipase (PNLIP), pancreatic lipase-related protein 2 (PNLIPRP2), and carboxyl ester lipase (CEL), which may leak into the visceral fat or systemic circulation during pancreatitis. We, thus, aimed to determine the pancreatic lipase(s) regulating lipotoxicity during AP. For this AP, associated fat necrosis was analyzed using Western blot analysis. Bile acid (using liquid chromatography-tandem mass spectrometry) and fatty acid (using gas chromatography) concentrations were measured in human fat necrosis. The fat necrosis milieu was simulated in vitro using glyceryl trilinoleate because linoleic acid is increased in fat necrosis. Bile acid requirements to effectively hydrolyze glyceryl trilinoleate were studied using exogenous or overexpressed lipases. The renal cell line (HEK 293) was used to study lipotoxic injury. Because dual pancreatic lipase knockouts are lethal, exocrine parotid acini lacking lipases were used to verify the results. PNLIP, PNLIPRP2, and CEL were increased in fat necrosis. Although PNLIP and PNLIPRP2 were equipotent in inducing lipolysis and lipotoxic injury, CEL required bile acid concentrations higher than in human fat necrosis. The high bile acid requirements for effective lipolysis make CEL an unlikely mediator of lipotoxic injury in AP. It remains to be explored whether PNLIP or PNLIPRP2 worsens AP severity in vivo.

Abstract
BACKGROUND/OBJECTIVES A high body mass index increases the risk of severe pancreatitis and associated mortality. Our aims were: (1) To determine whether obesity affects the release of extracellular nucleosomes in patients with pancreatitis; (2) To determine whether pancreatic ascites confers lipotoxicity and triggers the release of extracellular nucleosomes in lean and obese rats. METHODS DNA and nucleosomes were determined in plasma from patients with mild or moderately severe acute pancreatitis either with normal or high body mass index (BMI). Lipids from pancreatic ascites from lean and obese rats were analyzed and the associated toxicity measured in vitro in RAW 264.7 macrophages. The inflammatory response, extracellular DNA and nucleosomes were determined in lean or obese rats with pancreatitis after peritoneal lavage. RESULTS Nucleosome levels in plasma from obese patients with mild pancreatitis were higher than in normal BMI patients; these levels markedly increased in obese patients with moderately severe pancreatitis vs. those with normal BMI. Ascites from obese rats exhibited high levels of palmitic, oleic, stearic, and arachidonic acids. Necrosis and histone 4 citrullination-marker of extracellular traps-increased in macrophages incubated with ascites from obese rats but not with ascites from lean rats. Peritoneal lavage abrogated the increase in DNA and nucleosomes in plasma from lean or obese rats with pancreatitis. It prevented fat necrosis and induction of HIF-related genes in lung. CONCLUSIONS Extracellular nucleosomes are intensely released in obese patients with acute pancreatitis. Pancreatitis-associated ascitic fluid triggers the release of extracellular nucleosomes in rats with severe pancreatitis.

Abstract
BACKGROUND In Asian population, there is limited information on the relevance between obesity and poor outcomes in acute pancreatitis (AP). The objective of this study was to examine the clinical impact of obesity based on body mass index (BMI) on prognosis of AP in Japanese patients. METHODS A total of 116 patients with AP were enrolled in this study. Univariate and multivariate logistic regression analyses were performed to examine relations between BMI and patients' outcomes. Additionally, to investigate whether including obesity as a prognostic factor improved the predictive accuracy of a Japanese prognostic factor score (PF score), a receiver-operating characteristic (ROC) curve analysis of mortality was conducted. RESULTS Multiple logistic regression analyses revealed that BMI =25 kg/m2 was associated with a significant higher mortality [odds ratio (OR)=15.8; 95% confidence interval (CI): 1.1-227; P=0.043]. The area under the ROC curve (AUC) for the combination of PF score and BMI =25 kg/m2 (AUC=0.881; 95% CI: 0.809-0.952) was higher than that for the PF score alone (AUC=0.820; 95% CI: 0.713-0.927) (P=0.034). CONCLUSIONS The negative impact of a high BMI on the prognosis of AP was confirmed in a Japanese population. Including BMI =25 kg/m2 as an additional parameter to PF score enhanced the predictive value of the PF score for AP-related mortality.

Abstract
PURPOSE OF REVIEW The obesity pandemic poses a unique set of problems for acute pancreatitis - both by increasing acute pancreatitis incidence, and worsening acute pancreatitis severity. This review explores these associations, underlying mechanisms, and potential therapies. RECENT FINDINGS We review how the obesity associated increase in gallstones, surgical, and endoscopic interventions for obesity management, diabetes, and related medications such as incretin-based therapies and hypertriglyceridemia may increase the incidence of acute pancreatitis. The mechanism of how obesity may increase acute pancreatitis severity are discussed with a focus on cytokines, adipokines, damage-associated molecular patterns and unsaturated fatty acid-mediated lipotoxicity. The role of obesity in exacerbating pancreatic necrosis is discussed; focusing on obesity-associated pancreatic steatosis. We also discuss how peripancreatic fat necrosis worsens organ failure independent of pancreatic necrosis. Last, we discuss emerging therapies including choice of intravenous fluids and the use of lipase inhibitors which have shown promise during severe acute pancreatitis. SUMMARY We discuss how obesity may contribute to increasing acute pancreatitis incidence, the role of lipolytic unsaturated fatty acid release in worsening acute pancreatitis, and potential approaches, including appropriate fluid management and lipase inhibition in improving acute pancreatitis outcomes.

Abstract
Background The aim of the present study was to investigate risk factors for developing more severe pancreatitis, including moderately severe (MSAP) and severe acute pancreatitis (SAP), in patients admitted with mild acute pancreatitis (MAP). Material/Methods Patients admitted with MAP to our hospital from March 2013 to May 2016 were included and prospectively evaluated. Possible risk factors for developing MSAP or SAP were age, blood glucose level on admission, etiology, sex, Ranson score, amylase level, Acute Physiology and Chronic Health Evaluation II (APACHE-II) scores, C-reactive protein (CRP) level, serum calcium level, visceral fat area (VFA), body mass index (BMI), whether this was the first episode of AP, and method of administration of octreotide. The effects of variables for developing MSAP or SAP were evaluated using univariate and multivariate logistic regression models. Mortality, hospital duration, and rate of ICU transfer of patients were compared between patients who developed MSAP or SAP and patients who did not. Results A total of 602 patients admitted with MAP were recruited into this study (256 men and 346 women). Seventy-four patients (12.3%) developed MSAP or SAP. According to univariate logistic regression analyses, the results indicated that there were 5 significant differences between patients who developed MSAP or SAP and those who did not: VFA (>100 cm2) (p=0.003), BMI (≥25 kg/m2) (p=0.001), Ranson score(p=0.004), APACHE-II (≥5) (p=0.001), and blood glucose level on admission (>11.1 mmol/L) (p=0.040). Further multivariate logistic regression analyses revealed that BMI (≥25 kg/m2) (p=0.005), APACHE-II (≥5) (p=0.001), and blood glucose level on admission (>11.1 mmol/L) (p=0.004) were independent risk factors for developing MSAP or SAP in patients admitted with MAP. Moreover, patients who developed MSAP or SAP had a mortality rate of 5.4%. Conclusions Significant risk factors for developing MSAP or SAP in patients admitted with MAP included BMI (≥25 kg/m2), APACHE-II (≥5), and blood glucose level on admission (>11.1 mmol/L). These factors should be used in the prediction of more severe pancreatitis in patients admitted with MAP.

Abstract
Obesity is a well-recognized risk factor for gallstone formation and increases the risk for gallstone-related complications. Pancreatic diseases are impacted adversely by obesity. Although weight loss surgery increases the risk of gallstone disease, evidence suggests that bariatric surgery mitigates the obesity-associated adverse prognostication in acute pancreatitis. Obesity is also a significant risk factor for pancreatic cancer. Obesity is a global epidemic and is increasing worldwide and among all age groups. There is an urgent need for focused health policies aimed at reducing the incidence and prevalence of obesity. This article summarizes the current literature highlighting the association between obesity and the pathophysiology and outcome of gallstone disease, pancreatitis, and pancreatic cancer.

Abstract
Objective The aim of this study was to analyse the clinical characteristics of acute pancreatitis (AP) in a prospectively collected, large, multicentre cohort and to validate the major recommendations in the IAP/APA evidence-based guidelines for the management of AP. Design Eighty-six different clinical parameters were collected using an electronic clinical research form designed by the Hungarian Pancreatic Study Group. Patients 600 adult patients diagnosed with AP were prospectively enrolled from 17 Hungarian centres over a two-year period from 1 January 2013. Main Results With respect to aetiology, biliary and alcoholic pancreatitis represented the two most common forms of AP. The prevalence of biliary AP was higher in women, whereas alcoholic AP was more common in men. Hyperlipidaemia was a risk factor for severity, lack of serum enzyme elevation posed a risk for severe AP, and lack of abdominal pain at admission demonstrated a risk for mortality. Abdominal tenderness developed in all the patients with severe AP, while lack of abdominal tenderness was a favourable sign for mortality. Importantly, lung injury at admission was associated with mortality. With regard to laboratory parameters, white blood cell count and CRP were the two most sensitive indicators for severe AP. The most common local complication was peripancreatic fluid, whereas the most common distant organ failure in severe AP was lung injury. Deviation from the recommendations in the IAP/APA evidence-based guidelines on fluid replacement, enteral nutrition and timing of interventions increased severity and mortality. Conclusions Analysis of a large, nationwide, prospective cohort of AP cases allowed for the identification of important determinants of severity and mortality. Evidence-based guidelines should be observed rigorously to improve outcomes in AP.

Abstract
Although ethanol causes acute pancreatitis (AP) and lipolytic fatty acid (FA) generation worsens AP, the contribution of ethanol metabolites of FAs, ie, FA ethyl esters (FAEEs), to AP outcomes is unclear. Previously, pancreata of dying alcoholics and pancreatic necrosis in severe AP, respectively, showed high FAEEs and FAs, with oleic acid (OA) and its ethyl esters being the most abundant. We thus compared the toxicities of FAEEs and their parent FAs in severe AP. Pancreatic acini and peripheral blood mononuclear cells were exposed to FAs or FAEEs in vitro. The triglyceride of OA (i.e., glyceryl tri-oleate) or OAEE was injected into the pancreatic ducts of rats, and local and systemic severities were studied. Unsaturated FAs at equimolar concentrations to FAEEs induced a larger increase in cytosolic calcium, mitochondrial depolarization, and necro-apoptotic cell death. Glyceryl tri-oleate but not OAEE resulted in 70% mortality with increased serum OA, a severe inflammatory response, worse pancreatic necrosis, and multisystem organ failure. Our data show that FAs are more likely to worsen AP than FAEEs. Our observations correlate well with the high pancreatic FAEE concentrations in alcoholics without pancreatitis and high FA concentrations in pancreatic necrosis. Thus, conversion of FAs to FAEE may ameliorate AP in alcoholics.

Abstract
Height measurement in the critical care unit is necessary for estimating ideal body weight and providing titrated patient care. In this study, we compare three methods of height assessment and evaluate their level of correlation and inter-observer reproducibility. Heights of 100 consecutive patients were assessed independently by two nurses by supine, four point, and arm span methods. Paired sample t-test, one-way analysis of variance, Tukey's honestly significant difference post-hoc analysis and Bland–Altman plots were performed to assess agreement between measurements. Arm span method showed higher mean height compared to supine and four point methods. Mean heights derived by supine and four point measurements were similar to each other but were significantly different from that of arm span method (P < 0.001). Inter-observer correlation of the measured heights was very good among all three methods. The supine method seems to be easy, accurate, and reproducible in our study.

Abstract
BACKGROUND AND AIMS Peripancreatic fat necrosis occurs frequently in necrotising pancreatitis. Distinguishing markers from mediators of severe acute pancreatitis (SAP) is important since targeting mediators may improve outcomes. We evaluated potential agents in human pancreatic necrotic collections (NCs), pseudocysts (PCs) and pancreatic cystic neoplasms and used pancreatic acini, peripheral blood mononuclear cells (PBMC) and an acute pancreatitis (AP) model to determine SAP mediators. METHODS We measured acinar and PBMC injury induced by agents increased in NCs and PCs. Outcomes of caerulein pancreatitis were studied in lean rats coadministered interleukin (IL)-1β and keratinocyte chemoattractant/growth-regulated oncogene, triolein alone or with the lipase inhibitor orlistat. RESULTS NCs had higher fatty acids, IL-8 and IL-1β versus other fluids. Lipolysis of unsaturated triglyceride and resulting unsaturated fatty acids (UFA) oleic and linoleic acids induced necro-apoptosis at less than half the concentration in NCs but other agents did not do so at more than two times these concentrations. Cytokine coadministration resulted in higher pancreatic and lung inflammation than caerulein alone, but only triolein coadministration caused peripancreatic fat stranding, higher cytokines, UFAs, multisystem organ failure (MSOF) and mortality in 97% animals, which were prevented by orlistat. CONCLUSIONS UFAs, IL-1β and IL-8 are elevated in NCs. However, UFAs generated via peripancreatic fat lipolysis causes worse inflammation and MSOF, converting mild AP to SAP.

Abstract
OBJECTIVES Morbid obesity may adversely affect the clinical course of acute pancreatitis (AP); however, there are no inpatient, population-based studies assessing the impact of morbid obesity on AP-related outcomes. We sought to evaluate the impact of morbid obesity on AP-related clinical outcomes and health-care utilization. METHODS The Nationwide Inpatient Sample (2007-2011) was reviewed to identify all adult inpatients (≥18 years) with a principal diagnosis of AP. The primary clinical outcomes (mortality, renal failure, and respiratory failure) and secondary resource outcomes (length of stay and hospital charges) were analyzed using univariate and multivariate comparisons. Propensity score-matched analysis was performed to compare the outcomes in patients with and without morbid obesity. RESULTS Morbid obesity was associated with 3.9% (52,297/1,330,302) of all AP admissions. Whereas the mortality rate decreased overall (0.97%→0.83%, P<0.001), it remained unchanged in those with morbid obesity (1.02%→1.07%, P=1.0). Multivariate analysis revealed that morbid obesity was associated with increased mortality (odds ratio (OR) 1.6; 95% confidence interval (CI) 1.3, 1.9), prolonged hospitalization (0.4 days; P<0.001), and higher hospitalization charges ($5,067; P<0.001). A propensity score-matched cohort analysis demonstrated that the primary outcomes, acute kidney failure (10.8 vs. 8.2%; P<0.001), respiratory failure (7.9 vs. 6.4%; P<0.001), and mortality (OR 1.6, 95% CI 1.2, 2.1) were more frequent in morbid obesity. CONCLUSIONS Morbid obesity negatively influences inpatient hospitalization and is associated with adverse clinical outcomes, including mortality, organ failure, and health-care resource utilization. These observations and the increasing global prevalence of obesity justify ongoing efforts to understand the role of obesity-induced inflammation in the pathogenesis and management of AP.

Lipolysis of visceral adipocyte triglyceride by pancreatic lipases converts mild acute pancreatitis to severe pancreatitis independent of necrosis and inflammation.

Abstract
Visceral fat necrosis has been associated with severe acute pancreatitis (SAP) for over 100 years; however, its pathogenesis and role in SAP outcomes are poorly understood. Based on recent work suggesting that pancreatic fat lipolysis plays an important role in SAP, we evaluated the role of pancreatic lipases in SAP-associated visceral fat necrosis, the inflammatory response, local injury, and outcomes of acute pancreatitis (AP). For this, cerulein pancreatitis was induced in lean and obese mice, alone or with the lipase inhibitor orlistat and parameters of AP induction (serum amylase and lipase), fat necrosis, pancreatic necrosis, and multisystem organ failure, and inflammatory response were assessed. Pancreatic lipases were measured in fat necrosis and were overexpressed in 3T3-L1 cells. We noted obesity to convert mild cerulein AP to SAP with greater cytokines, unsaturated fatty acids (UFAs), and multisystem organ failure, and 100% mortality without affecting AP induction or pancreatic necrosis. Increased pancreatic lipase amounts and activity were noted in the extensive visceral fat necrosis of dying obese mice. Lipase inhibition reduced fat necrosis, UFAs, organ failure, and mortality but not the parameters of AP induction. Pancreatic lipase expression increased lipolysis in 3T3-L1 cells. We conclude that UFAs generated via lipolysis of visceral fat by pancreatic lipases convert mild AP to SAP independent of pancreatic necrosis and the inflammatory response.

Abstract
Obese patients have worse outcomes during acute pancreatitis (AP). Previous animal models of AP have found worse outcomes in obese rodents who may have a baseline proinflammatory state. Our aim was to study the role of acute lipolytic generation of fatty acids on local severity and systemic complications of AP. Human postpancreatitis necrotic collections were analyzed for unsaturated fatty acids (UFAs) and saturated fatty acids. A model of biliary AP was designed to replicate the human variables by intraductal injection of the triglyceride glyceryl trilinoleate alone or with the chemically distinct lipase inhibitors orlistat or cetilistat. Parameters of AP etiology and outcomes of local and systemic severity were measured. Patients with postpancreatitis necrotic collections were obese, and 13 of 15 had biliary AP. Postpancreatitis necrotic collections were enriched in UFAs. Intraductal glyceryl trilinoleate with or without the lipase inhibitors resulted in oil red O-positive areas, resembling intrapancreatic fat. Both lipase inhibitors reduced the glyceryl trilinoleate-induced increase in serum lipase, UFAs, pancreatic necrosis, serum inflammatory markers, systemic injury, and mortality but not serum alanine aminotransferase, bilirubin, or amylase. We conclude that UFAs are enriched in human necrotic collections and acute UFA generation via lipolysis worsens pancreatic necrosis, systemic inflammation, and injury associated with severe AP. Inhibition of lipolysis reduces UFA generation and improves these outcomes of AP without interfering with its induction.

Abstract
BACKGROUND With the rising prevalence of obesity, its impact on the severity and outcome of acute pancreatitis remains an important consideration when managing obese patients with acute pancreatitis. OBJECTIVE To determine the clinical relevance of obesity in acute pancreatitis. METHODS A series of clinically relevant questions were framed which formed the basis of our literature search using PubMed and EMBASE databases. These related to acute pancreatitis severity, systemic inflammatory response, mortality, local and systemic complications. The search was restricted to human studies. Studies were classified according to the Oxford Centre for Evidence Based Medicine levels of evidence 1 for prognostic studies. Obesity was defined according to the guidelines of the World Health Organization. In keeping with studies included the binary classification (mild and severe) of acute pancreatitis was used. RESULTS Obesity is associated with an amplified systemic inflammatory response in acute pancreatitis and is a prognostic factor for mortality, local, systemic complications and severity in acute pancreatitis. Obesity was not found to be an independent prognostic factor for mortality and organ failure in patients with acute pancreatitis. It was evident that further studies are required to determine whether incorporating obesity into existing scoring systems improves severity prediction. Emerging evidence suggests that an obesity paradox is present in patients with acute pancreatitis. CONCLUSION This review demonstrates that obesity has a clinically relevant impact on the course and outcome of acute pancreatitis.

Abstract
The role of obesity in relation to various disease processes is being increasingly studied, with reports over the last several years increasingly mentioning its association with worse outcomes in acute disease. Obesity has also gained recognition as a risk factor for severe acute pancreatitis (SAP).The mortality in SAP may be as high as 30% and is usually attributable to multi system organ failure (MSOF) earlier in the disease, and complications of necrotizing pancreatitis later [9-11]. To date there is no specific treatment for acute pancreatitis (AP) and the management is largely expectant and supportive. Obesity in general has also been associated with poor outcomes in sepsis and other pathological states including trauma and burns. With the role of unsaturated fatty acids (UFA) as propagators in SAP having recently come to light and with the recognition of acute lipotoxicity, there is now an opportunity to explore different strategies to reduce the mortality and morbidity in SAP and potentially other disease states associated with such a pathophysiology. In this review we will discuss the role of fat and implications of the consequent acute lipotoxicity on the outcomes of acute pancreatitis in lean and obese states and during acute on chronic pancreatitis.

Abstract
BACKGROUND & AIMS Acute pancreatitis (AP) and chronic pancreatitis (CP) share etiologies, but AP can be more severe and is associated with a higher rate of mortality. We investigated features of CP that protect against severe disease. The amount of intrapancreatic fat (IPF) is increased in obese patients and fibrosis is increased in patients with CP, so we studied whether fibrosis or fat regulate severity of AP attacks in patients with CP. METHODS We reviewed records from the University of Pittsburgh Medical Center/Presbyterian Hospital Autopsy Database (1998-2008) for patients with a diagnosis of AP (n = 23), CP (n = 35), or both (AP-on-CP; n = 15). Pancreatic histology samples from these patients and 50 randomly selected controls (no pancreatic disease) were analyzed, and IPF data were correlated with computed tomography data. An adipocyte and acinar cell Transwell coculture system, with or without collagen type I, was used to study the effects of fibrosis on acinar-adipocyte interactions. We studied the effects of nonesterified fatty acids (NEFAs) and adipokines on acinar cells in culture. RESULTS Levels of IPF were significantly higher in nonobese patients with CP than in nonobese controls. In patients with CP or AP-on-CP, areas of IPF were surrounded by significantly more fibrosis than in controls or patients with AP. Fat necrosis-associated peri-fat acinar necrosis (PFAN, indicated by NEFA spillage) contributed to most of the necrosis observed in samples from patients with AP; however, findings of peri-fat acinar necrosis and total necrosis were significantly lower in samples from patients with CP or AP-on-CP. Fibrosis appeared to wall off the fat necrosis and limit peri-fat acinar necrosis, reducing acinar necrosis. In vitro, collagen I limited the lipolytic flux between acinar cells and adipocytes and prevented increases in adipokines in the acinar compartment. This was associated with reduced acinar cell necrosis. However, NEFAs, but not adipokines, caused acinar cell necrosis. CONCLUSIONS Based on analysis of pancreatic samples from patients with CP, AP, or AP-on-CP and in vitro studies, fibrosis reduces the severity of acute exacerbations of CP by reducing lipolytic flux between adipocytes and acinar cells.

Abstract
Background Controversy still exists on the effect that obesity has on the morbidity and mortality in severe acute pancreatitis (SAP). The primary purpose of this study was to compare the mortality rate of obese versus nonobese patients admitted to the ICU for SAP. Secondary goals were to assess the potential risk factors for abdominal compartment syndrome (ACS) and to investigate the performance of validated scoring systems to predict ACS and in-hospital mortality. Methods A retrospective cohort of adults admitted to the ICU for SAP was stratified by their body mass index (BMI) as obese and nonobese. The rates of morbidity, mortality, and ACS were compared by univariate and multivariate regression analyses. Areas under the curve (AUC) were used to evaluate the discriminating performance of severity scores and other selected variables to predict mortality and the risk of ACS. Result Forty-five patients satisfied the inclusion criteria and 24 (53 %) were obese with similar characteristics to nonobese patients. Among all the subjects, 11 (24 %) died and 16 (35 %) developed ACS. In-hospital mortality was significantly lower for obese patients (12.5 vs. 38 %; P = 0.046) even though they seemed to develop ACS more frequently (41 vs. 28 %; P = 0.533). At multivariable analysis, age was the most significant factor associated with in-hospital mortality (odds ratio (OR) = 1.273; 95 % confidence interval (CI) 1.052–1.541; P = 0.013) and APACHE II and Glasgow-Imrie for the development of ACS (OR = 1.143; 95 % CI 1.012–1.292; P = 0.032 and OR = 1.221; 95 % CI 1.000–1.493; P = 0.05) respectively. Good discrimination for in-hospital mortality was observed for patients’ age (AUC = 0.846) and number of comorbidities (AUC = 0.801). ACS was not adequately predicted by any of the clinical severity scores (AUC = 0.548–0.661). Conclusions Patients’ age was the most significant factor associated with mortality in patients affected by SAP. Higher APACHE II and Glasgow-Imrie scores were associated with the development of ACS, but their discrimination performance was unsatisfactory.

Abstract
Excess body fat is widely considered one of the factors that is linked to acute pancreatitis (AP), but its specific role is far from being fully understood. This Editorial offers an insight into the recent research in this field with particular emphasis on findings of the latest prospective population-based studies. It discusses whether body fat distribution influences the risk of developing first-time AP, whether excess body fat affects clinically meaningful outcomes in patients with developed AP, and whether a case can be made for biological interaction between several metabolic components in this disease.

Abstract
BACKGROUND Obesity is a prognostic factor for severity in acute pancreatitis in humans. Our aim was to assess the role of oxidative stress and abdominal fat in the increased severity of acute pancreatitis in obese rats. METHODOLOGY Taurocholate-induced acute pancreatitis was performed in lean and obese Zucker rats. Levels of reduced glutathione, oxidized glutathione, L-cysteine, cystine, and S-adenosylmethionine were measured in pancreas as well as the activities of serine/threonine protein phosphatases PP1 and PP2A and tyrosin phosphatases. Isoprostane, malondialdehyde, triglyceride, and free fatty acid levels and lipase activity were measured in plasma and ascites. Lipase activity was measured in white adipose tissue with and without necrosis and confirmed by western blotting. FINDINGS Under basal conditions obese rats exhibited lower reduced glutathione levels in pancreas and higher triglyceride and free fatty acid levels in plasma than lean rats. S-adenosyl methionine levels were markedly increased in pancreas of obese rats. Acute pancreatitis in obese rats led to glutathione oxidation and lower reduced glutathione levels in pancreas together with decreased activities of redox-sensitive phosphatases PP1, and PP2A. S-adenosyl methionine levels decreased but cystine levels increased markedly in pancreas upon pancreatitis. Acute pancreatitis triggered an increase in isoprostane levels in plasma and ascites in obese rats. Free fatty acid levels were extremely high in pancreatitis-associated ascitic fluid from obese rats and lipase was bound with great affinity to white adipose tissue, especially to areas of necrosis. CONCLUSIONS Our results show that oxidative stress occurs locally and systemically in obese rats with pancreatitis favouring inactivation of protein phosphatases in pancreas, which would promote up-regulation of pro-inflammatory cytokines, and the increase of isoprostanes which might cause powerful pulmonary and renal vasoconstriction. Future studies are needed to confirm the translational relevance of the present findings obtained in a rat model of taurocholate-induced pancreatic damage and necrosis.

Abstract
Obesity increases the risk of adverse outcomes during acute critical illnesses such as burns, severe trauma, and acute pancreatitis. Although individuals with more body fat and higher serum cytokines and lipase are more likely to experience problems, the roles that these characteristics play are not clear. We used severe acute pancreatitis as a representative disease to investigate the effects of obesity on local organ function and systemic processes. In obese humans, we found that an increase in the volume of intrapancreatic adipocytes was associated with more extensive pancreatic necrosis during acute pancreatitis and that acute pancreatitis was associated with multisystem organ failure in obese individuals. In vitro studies of pancreatic acinar cells showed that unsaturated fatty acids were proinflammatory, releasing intracellular calcium, inhibiting mitochondrial complexes I and V, and causing necrosis. Saturated fatty acids had no such effects. Inhibition of lipolysis in obese (ob/ob) mice with induced pancreatitis prevented a rise in serum unsaturated fatty acids and prevented renal injury, lung injury, systemic inflammation, hypocalcemia, reduced pancreatic necrosis, and mortality. Thus, therapeutic approaches that target unsaturated fatty acid-mediated lipotoxicity may reduce adverse outcomes in obese patients with critical illnesses such as severe acute pancreatitis.

Abstract
OBJECTIVE To provide a meta-analyisis on whether obesity could be a prognostic indicator on the severity, development of complications and mortality of acute pancreatitis (AP). METHODS Eligible articles were retrieved using electronic databases. Clinical studies evaluating the association between obesity and disease course of patients with AP were included. Weighted mean difference (WMD) and 95% confidence interval (CI) were estimated and pooled using RevMan 4.2.8. RESULTS In all, 12 clinical studies with a total of 1483 patients were included in the analysis. Obese patients had a significantly increased risk of severe acute pancreatitis (SAP; RR=2.20, 95% CI 1.82-2.66, P<0.05), local complication (RR=2.68, 95% CI 2.09-3.43, P<0.05), systemic complication (RR=2.14, 95% CI 1.42-3.21, P<0.05) and in-hospital mortality (RR=2.59, 95% CI 1.66-4.03, P<0.05) compared with non-obese patients. CONCLUSIONS Obesity is a definite risk factor of morbidity and in-hospital mortality for AP and may serve as a prognostic indicator.

Abstract
OBJECTIVE BMI has been indicated to be associated with prognosis of acute pancreatitis (AP). However, the relationship between BMI and the risk of AP development is still unresolved. We examined this association by conducting a detailed meta-analysis. We also assessed its prognostic role by including more researches. METHODS Studies were identified by searching MEDLINE and EMBASE through March 31, 2011. There were two end points in this meta-analysis: the risk of AP development and the outcome of AP (including severity, local complications, systemic complications, and mortality). Summary relative risks (SRRs) with their corresponding 95% confidence intervals (CIs) were calculated using a random-effects model. RESULTS Compared with normal weight individuals, obese individuals (BMI>30 kg/m²) had an increased risk of AP development (SRRs 1.34, 95% CI: 1.07-1.68), with significant heterogeneity among these studies (P=0.002, I²=77.2%). In addition, compared with nonobese patients, obese patients developed significantly more severe AP (SRRs 1.82, 95% CI: 1.44-2.30), systemic complications (SRRs 1.71, 95% CI: 1.17-2.50), local complications (SRRs 2.32, 95%CI: 1.79-3.00), and mortality (SRRs 2.21, 95% CI: 1.28-3.83). There was no heterogeneity among these studies. CONCLUSION Findings from this meta-analysis indicated that obesity is not only associated with an increased risk of AP development, but it is also a poor prognostic factor for AP.

Abstract
BACKGROUND Obesity plays an important role in acute pancreatitis. Assuming that the volume of visceral adipose tissue (VAT) directly influences the severity of acute pancreatitis, we investigated the relationship between VAT and acute pancreatitis. METHODS Data were collected consecutively from 124 patients who were diagnosed with acute pancreatitis. Body mass index (BMI) was calculated from the database. Computed tomography was performed in all patients, and VAT, subcutaneous adipose tissue (SAT), and waist circumference (WC) were measured at the level of the intervertebral disk between L2 and L3. Atlanta criteria were adopted to define severe acute pancreatitis. Clinical courses were investigated, and the Ranson and acute physiology and chronic health evaluation II (APACHE II) scores were calculated for all patients. RESULTS Forty-eight patients had severe acute pancreatitis (38.7%), and 76 were mild cases. BMI, VAT, SAT, and WC were correlated with the severity of acute pancreatitis in a univariate analysis, but only VAT had a strong correlation with severe acute pancreatitis in the multivariate analysis. In a trend analysis, not only severity but also the presence of pseudocysts (local complication) and prognostic factors (Ranson and APACHE II scores) were significantly related to VAT volume. In particular, the presence of a pancreatic pseudocyst was strongly related to VAT volume (p < 0.001). CONCLUSION In acute pancreatitis, peripancreatic VAT has a stronger correlation with severe acute pancreatitis than BMI or WC. VAT volume is strongly correlated with the formation of a pseudocyst and with systemic inflammatory response syndrome in patients with acute pancreatitis and high VAT volume may lead to severe acute pancreatitis.

Abstract
BACKGROUND/AIMS Obesity is a known risk factor for severe acute pancreatitis (AP). Since alcoholic chronic pancreatitis (ACP) is closely linked to alcoholic AP, overweight before disease onset might impact on incidence and outcome of ACP, and represent an additional risk factor for ACP. This issue has not been investigated, despite discussions on the 'hypercaloric-high-fat' hypothesis as an additional risk factor for ACP for many years. METHODS The study is part of our prospective long-term study of a large, mixed, medical/surgical series of ACP patients. All cooperative patients were studied according to a protocol regarding clinical symptoms, physical status, routine laboratory tests, pancreatic function and pancreatic morphology (e.g. calcification) at yearly follow-ups. Our study includes 227 ACP patients with recorded body mass index (BMI) before disease onset followed up on average for 18 years from chronic pancreatitis (CP) onset. RESULTS Males predominated (89.9%), age at onset averaged at 36 years, and exocrine insufficiency (97.4%) and calcification (88.1%) developed in virtually all patients. Surgery for B-type pain was performed in 57.7%, and death occurred in 62.8%. Overweight before disease onset was found in 54.2% (obesity in 15.0%) compared to 37.7% (3.1%) from a contemporary male control population. The highest BMI before disease onset did not impact on some major variables of ACP such as gender, age, progression of exocrine insufficiency, diabetes and calcification, and mortality from CP, except for a delayed progression rate of ACP indices in the surgical series. CONCLUSION Overweight before disease onset appears to be another risk factor for ACP, supporting the 'hypercaloric-high-fat' hypothesis. and IAP.

Abstract
Background To propose simple tests for the prediction of severe acute pancreatitis (SAP), which are accurate and could be performed at emergency departments and outpatient clinics. Methods A prospective study was performed on 149 patients admitted with acute pancreatitis. Body mass index (BMI), plain chest radiograph, blood biochemical data were obtained at the time of admission; white cell, lymphocyte and platelet counts, hematocrit level, prothrombin time, PaO2, creatinine, calcium, blood sugar, total protein, aspartate aminotransferase, total bilirubin, amylase, lipase and C-reaction protein were determined. Patients were graded into severe and mild acute pancreatitis based on CT Balthazar grading system. Results Twenty-seven patients were diagnosed to have SAP and 122 patients considered mild acute pancreatitis. Comparing parameters between both groups; significant factors (P < 0.05) were blood sugar level, haematocrit level, BMI and presence of pleural effusion in chest X-ray. The hematocrit at admission and at approximately 24 hours was significantly higher among patients with SAP. Twenty-two of 27 cases of severe disease and only 10 of 122 cases of mild acute pancreatitis diagnosed to have pleural effusion (P < 0.001). Conclusion BMI, blood glucose ≥ 190 mg/dL, hematocrit level ≥ 43 % and pleural effusion detected by plain chest radiograph are simple tests and provide significant predictive power for clinical decision-making.

Abstract
BACKGROUND/AIMS Little is known about risk factors for acute pancreatitis other than gallstones and alcohol consumption. The aim of this study was to investigate if smoking or body mass index (BMI) are associated with acute pancreatitis and to determine relative risks (RR) for acute pancreatitis related to smoking, BMI, and alcohol consumption. METHODS From 1974 to 1992, selected birth-year cohorts of residents in Malmo, Sweden (born 1921-1949) were invited to a health-screening investigation including physical examination, blood sampling and a questionnaire. In total, 33,346 individuals participated. Cases of acute pancreatitis were identified from diagnosis registries (n = 179). Incidence rates were calculated in different risk factor categories. A Cox's analysis revealed RR. RESULTS Current versus never smoking at baseline was associated with acute pancreatitis (RR 2.14, 95% confidence interval (CI) 1.48-3.09) after adjustment for age, sex, BMI and alcohol consumption. This association was stronger in heavy smokers (20-30 cigarettes/day) (RR 3.19, 95% CI 2.03-5.00). Smoking was associated with a RR of 3.57 (95% CI 0.98-13.0) for acute pancreatitis in subjects who reported no alcohol consumption. An increased risk for acute pancreatitis was also found for high versus low risk, self-reported alcohol consumption (RR 2.55, 95% CI 1.59-4.08) and for gamma-GT levels in the highest versus the lowest quartile (RR 2.14, 95% CI 1.32-3.49). There was also a weak correlation between BMI and acute pancreatitis. CONCLUSIONS Smoking is associated with the incidence of acute pancreatitis in a dose-response manner. and IAP.

Abstract
Obesity has reached epidemic proportions in many countries and is an established risk factor in many chronic illnesses, but its role in acute illness is less clear. Pancreatologists have long recognized obesity as a risk factor for a poor outcome in severe acute pancreatitis. There are now several studies that have identified obesity as a primary risk factor for developing local complications (abscess, pseudocyst, necrosis), organ failure, and death. Indeed, meta-analysis of these studies gives a relative risk of 4.3 for local complications, 2.0 for systemic complications, and 2.1 for death. This has led to proposed modifications of acute pancreatitis scoring systems to include obesity as an independent primary predictive factor of severe disease. Obesity is associated with a low-grade inflammatory state, which may predispose obese patients to such complications. Furthermore, visceral obesity and visceral adipose tissue may be particularly important in underlying the pathophysiology of these observations.

Abstract
PURPOSE OF REVIEW New understanding of the dynamic of acute pancreatitis, the clinical impact of local pathology in chronic pancreatitis and cystic neoplastic lesions bearing high potential for malignant transformation has changed the management of pancreatic diseases. RECENT FINDINGS In acute pancreatitis, risk factors independently determining outcome in severe acute pancreatitis are early and persistent multiorgan failure, infected necrosis and extended sterile necrosis. The management of severe acute pancreatitis is based on early intensive-care treatment and late surgical debridement. In chronic pancreatitis, recent data from randomized controlled clinical trials have demonstrated duodenum-preserving pancreatic head resection with an inflammatory mass of the head as superior to pylorus-preserving Whipple resection. Cystic neoplasms are local lesions of the pancreas with high malignant potential. Local organ-preserving resection techniques have been applied with low morbidity and mortality, replacing a Whipple-type resection. Resection of pancreatic cancer is ineffective to cure patients. After an R0-resection, a significant survival benefit has been achieved when adjuvant chemotherapy has additionally been applied. SUMMARY New knowledge about the nature of inflammatory diseases, cystic neoplastic lesions and malignant pancreatic tumours has changed the indication for surgical treatment and the application of organ-preserving surgical techniques.

Abstract
This article addresses the criteria for severity assessment and the severity scoring system of the Ministry of Health and Welfare of Japan; now the Japanese Ministry of Health, Labour, and Welfare (the JPN score). It also presents data comparing the JPN score with the Acute Physiology and Chronic Health Evaluation (APACHE) II score and the Ranson score, which are the major measuring scales used in the United States and Europe. The goal of investigating these scoring systems is the achievement of earlier diagnosis and more appropriate and successful treatment of severe or moderate acute pancreatitis, which has a high mortality rate. This article makes the following recommendations in terms of assessing the severity of acute pancreatitis: (1) Severity assessment is indispensable to the selection of proper initial treatment in the management of acute pancreatitis (Recommendation A). (2) Assessment by a severity scoring system (JPN score, APACHE II score) is important for determining treatment policy and identifying the need for transfer to a specialist unit (Recommendation A). (3) C-reactive protein (CRP) is a useful indicator for assessing severity (Recommendation A). (4) Contrast-enhanced computed tomography (CT) scanning and contrast-enhanced magnetic resonance imaging (MRI) play an important role in severity assessment (Recommendation A). (5) A JPN score of 2 or more (severe acute pancreatitis) has been established as the criterion for hospital transfer (Recommendation A). (6) It is preferable to transfer patients with severe acute pancreatitis to a specialist medical institution where they can receive continuous monitoring and systemic management.

Abstract
While interstitial acute pancreatitis usually takes a benign course, necrotizing acute pancreatitis takes a severe course, mainly because of severe local and systemic complications. After a quick diagnosis it is necessary to rapidly assess a degree of severity of the disease and thus the prognosis. The clinical picture and the result of imaging procedures do not always correspond. The management basically includes to treat pain as well as to administer fluid, electrolyte, protein and calories. In addition, systemic treatment of complications such as shock or respiratory and renal insufficiency--if occurring--is necessary. In case of pancreatic necrosis, prophylactic administration of pancreas-penetrable antibiotics is recommended to avoid infection. In the severely ill with infected pancreatic necrosis, surgery is the treatment of choice. In approximately 10% of all patients with alcohol-induced pancreatitis, there is a gradual transition to chronic pancreatitis.

Abstract
OBJECTIVE Subcutaneous administrations of monosodium glutamate (MSG) to neonatal animals result in obesity and induce the toxicity on the central nervous system, and furthermore, have an effect on entero-pancreatic hormone. The effect of MSG on the cell turnover of organs, especially the pancreas, has received little attention until now. This study was designed to examine the effect of MSG on pancreatic cell turnover by immunohistochemistry and [(3)H]thymidine autoradiography. RESEARCH METHODS AND PROCEDURES Male JcI-ICR strain mice were SC injected with MSG (2 mg/g body weight daily) for 5 days after birth, received 112 repeated injections of [(3)H]thymidine at 6-hour intervals for 28 days after birth, and then were killed immediately thereafter, or 30, 60, or 120 days after the last injection. Autoradiography was performed on sections immunostained for glucagon, insulin, and somatostatin. RESULTS After continuous labeling, most pancreatic cells were labeled, and thereafter, labeling of cells decreased in control and MSG-treated mice. The mean grain counts of acinar cells in MSG-treated mice decreased more slowly than those in control mice. On the other hand, those of islet cells, including glucagon, insulin, and somatostatin cells, decreased more rapidly in MSG-treated mice than those in control mice. DISCUSSION Cell turnover of acinar cells was decelerated and that of islet cells including glucagon, insulin, and somatostatin cells was accelerated in MSG-treated mice pancreas. MSG-induced hypothalamic lesions exert the contrary influences on the cell turnover of acinar and islet cells.

Abstract
OBJECTIVE To evaluate risk factors, notably drugs, for acute pancreatitis. RESEARCH DESIGN AND METHODS A population-based case-control study was conducted of 1.4 million inhabitants, aged 20-85 years, of four regions in Sweden between 1 January 1995 and 31 May 1998. A total of 462 case subjects were hospitalized in surgery departments for their first episode of acute pancreatitis without previous gallbladder disease. A total of 1,781 control subjects were randomly selected from a population register. Information was obtained from case records and through telephone interviews. RESULTS A total of 27 case subjects (6%) and 55 control subjects (3%) had prevalent diabetes. A total of 53 case subjects (11%) and 130 control subjects (7%) had a BMI >30 kg/m(2). Use of glyburide had a crude odds ratio (OR) of 3.2 (95% CI 1.5-5.9), and in a multivariate logistic regression adjusted for covariates, the OR for use of glyburide was 2.5 (1.1-5.9). BMI had a continuous OR of 1.2 (1.1-1.4) per 5 units of BMI. The relative risk for hospitalization longer than 14 days or treatment in an intensive care unit was 2.4 (1.1-5.4) among patients with a BMI >30 kg/m(2) when compared with patients with a BMI between 20 and 25 kg/m(2). CONCLUSIONS Use of glyburide and obesity may both be risk factors for acute pancreatitis. Obesity is associated with an extended hospitalization time in subjects with acute pancreatitis.

Abstract
UNLABELLED Several prior studies have suggested that 80% of deaths in acute pancreatitis occur late as a result of pan-creatic infection. Others have suggested that approx half of deaths occur early as a result of multisystem organ failure. The aim of the present study was to determine the timing of mortality of acute pancreatitis at a large tertiary-care hospital in the United States. METHODS Patients with a diagnosis of acute pancreatitis (ICD-9 code 577.0) admitted to Brigham and Women's Hospital from October 1, 1982 to June 30, 1995 were retrospectively studied to determine total mortality, frequency of early vs late deaths, and clinical features of patients with early (< or = 14 d after admission) or late deaths (> 14 d after admission). RESULTS The overall mortality of acute pancreatitis was 2.1% (17 deaths among 805 patients). Eight deaths (47%) occurred within the first 14 d of hospitalization (median d 8, range 1-11 d), whereas 9 occurred after 14 d (median d 56, range 19-81). Early deaths resulted primarily from organ failure. Late deaths occurred postoperatively in 8 patients with infected or sterile necrosis and 1 patient with infected necrosis treated medically. CONCLUSION Approximately half of deaths in acute pancreatitis occur within the first 14 d owing to organ failure and the remainder of deaths occur later because of complications associated with necrotizing pancreatitis. Improvement in mortality in the future will require innovative approaches to counteract early organ failure and late complications of necrotizing pancreatitis.

Abstract
BACKGROUND The diagnosis, early assessment, and management of severe acute pancreatitis remain difficult clinical problems. This article presents the consensus obtained at a meeting convened to consider the evidence in these areas. The aim of the article is to provide outcome statements to guide clinical practice, with an assessment of the supporting evidence for each statement. METHOD Working groups considered the published evidence in the areas of diagnosis, assessment of severity, nonoperative treatment, and surgical treatment of severe acute pancreatitis. Outcome statements were defined to summarize the conclusions on each point considered. The findings were discussed and agreed on by all participants. A careful assessment was made of the strength of the available evidence (proven, probable, possible, unproven, or inappropriate). FINDINGS AND CONCLUSIONS There is reliable evidence to support much current practice. Clear guidance can be given in most areas examined, and several areas were identified where further investigation would be helpful. Diagnosis using plasma concentrations of pancreatic enzymes is reliable. Rapid advances are taking place in the assessment of severity. Several new therapeutic strategies show real promise for the reduction of morbidity and mortality rates. Surgical debridement is required for infected pancreatic necrosis, but is less often necessary for sterile necrosis.

Abstract
Although the overall mortality in sterile pancreatic necrosis is low, patients who experience systemic complications may have a higher mortality. To study the impact of systemic complications and other factors on survival, possible prognostic factors were evaluated among 26 patients who experienced at least one systemic complication. Mortality was 38%. Factors that correlated with a fatal outcome were high Ranson's scores during the first 48 hours (P = 0.01), high APACHE-II scores at admission (P = 0.04) and at 48 hours (P = 0.03), shock (P < 0.001), renal insufficiency (P < 0.05), multiple systemic complications (P < 0.001), and high body mass index (P = 0.01). Most systemic complications occurred during the first 2 weeks of illness. Logistic regression analysis showed that shock was the best predictor of a fatal outcome. Patients with favorable prognostic factors survived whether treated medically or surgically, whereas those with unfavorable factors had a fatal outcome whether treated medically or surgically. It is concluded that patients with severe sterile necrosis have a high mortality rate and that shock and other prognostic factors identify which patients are most likely to have a fatal outcome.
