RESUMEN
Diabetes mellitus following an episode of acute pancreatitis (AP) is an increasingly discussed complication, but there are sparse prospective data on the incidence and risk factors. We evaluated data from a prospective, multicenter observational cohort study that enrolled adults hospitalized with AP between 2017 and 2021 and followed them for one year. Ninety-eight participants who completed 12-month follow-up were included in this analysis. Diabetes status was assessed using a combination of measured glycated hemoglobin (HbA1c) at predetermined time intervals or physician diagnosis. In 68 participants without diabetes at enrollment, the cumulative incidence of new-onset diabetes was 4.4 % (n = 3) at 3 months and 10.3 % (n = 7) at 12 months. No differences were observed in demographic or pancreatitis-related characteristics between those who did versus did not develop diabetes, in part due to small sample size. In summary, new-onset diabetes was identified in approximately 10 % within one year after an episode of AP. Larger prospective studies are needed to further define the incidence, risk factors, and mechanisms of diabetes and pre-diabetes following AP. NCT03063398.

Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest types of cancer, and the increasing incidence of PDAC may be related to the prevalence of obesity. Physical activity (PA), a method known to mitigate obesity by increasing total energy expenditure, also modifies multiple cellular pathways associated with cancer hallmarks. Epidemiologic evidence has shown that PA can lower the risk of developing a variety of cancers, reduce some of the detrimental side effects of treatments, and improve patient's quality of life during cancer treatment. However, little is known about the pathways underlying the correlations observed between PA interventions and PDAC. Moreover, there is no standard dose of PA intervention that is ideal for PDAC prevention or as an adjuvant of cancer treatments. In this review, we summarize relevant literature showing how PDAC patients can benefit from PA, the potential of PA as an adjuvant treatment for PDAC, the studies using preclinical models of PDAC to study PA, and the clinical trials to date assessing the effects of PA in PDAC.

BACKGROUND: Hypertriglyceridemia (HTG) is considered within the top 5 etiologies in acute pancreatitis (AP), but the association of serum triglyceride (TG) levels with the clinical course of AP remains controversial. OBJECTIVES: This study aims to examine the effect of TG levels on severity of AP. METHODS: Patients were enrolled prospectively through APPRENTICE. High TG levels were defined based on the Endocrine Society Clinical Practice Guidelines. HTG was categorized as mild (serum TG levels 150-199 mg/dL), moderate (200-999 mg/dL), severe (1,000-1,999 mg/dL), and very severe (≥2,000 mg/dL). Severity of AP was based on the revised Atlanta classification criteria. RESULTS: Early TG levels were measured in 764 subjects and found elevated in 342 (120 with mild; 176, moderate; and 46, severe/very severe HTG). Patients with increased TG levels were younger (age ≥60, 16.7 vs. 30.3%), more likely to be male (66.1 vs. 51.2%), with more frequent alcohol use (62.8 vs. 50.7%), and diabetes mellitus (30.2 vs. 12.3%; all p ≤ 0.005). Severe AP (24.9 vs. 10.0%), ICU admission (32.5 vs. 19.7%), and mortality (5.3 vs. 1.7%; all p ≤ 0.005) were more frequently seen in patients with elevated TG levels. Based on multivariable analysis, elevated TG levels were independently associated with severe AP (p < 0.05). CONCLUSION: This large multicenter study confirms that elevated TG levels are associated with severe disease regardless of AP etiology.

Background and Aims: Endoscopic sleeve gastroplasty (ESG) is a minimally invasive bariatric procedure to induce weight loss through restrictive physiology. This study was designed to evaluate the fluoroscopic measurement of gastric dimensions after ESG as a predictor of Total Body Weight Loss (TBWL) over time. Methods: Post-ESG patients were enrolled prospectively between August 2013 and August 2019. An upper gastrointestinal (GI) fluoroscopy was obtained within 7 days after the procedure. Two blinded, independent radiologists reviewed fluoroscopic images and measured the gastric lumen transverse diameter in three separate areas of the fundus, body, and antrum. The primary outcome was achieving a TBWL of ten percent or more after ESG. Results: In total, 162 patients were included in the analysis (65% female) and had a mean body mass index (BMI) of 39 ± 6 at baseline. Patients had a mean maximum TBWL of 16.5 ± 8.3%. Respectively, 92%, 75%, and 50% of patients achieved a TBWL of 5%, 10%, or 15% or more. The mean post-procedural UGI gastric fundus/antrum transverse measurement ratio was 1.2 ± 0.6. A higher fundus-to-antrum ratio was significantly associated with a TBWL of 10% or more during follow-up in the multivariable model (OR 2.49, 95% CI 1.31-4.71; p-value 0.005). The prediction score based on the fundus-to-antrum ratio hd an area under the ROC curve of 0.79 (95% CI 0.75-0.83) for predicting a TBWL of 10% or more during follow-up. Conclusions: Measuring gastric the fundus/antrum ratio within one week of endoscopic sleeve gastroplasty (ESG) is a consistent and independent predictive measure of sustained TBWL during long-term follow-up.
RESUMEN
Acute pancreatitis (AP) is an acute inflammatory disorder that is common, costly, and is increasing in incidence worldwide with over 300,000 hospitalizations occurring yearly in the United States alone. As its course and outcomes vary widely, a critical knowledge gap in the field has been a lack of accurate prognostic tools to forecast AP patients' outcomes. Despite several published studies in the last three decades, the predictive performance of published prognostic models has been found to be suboptimal. Recently, non-regression machine learning models (ML) have garnered intense interest in medicine for their potential for better predictive performance. Each year, an increasing number of AP models are being published. However, their methodologic quality relating to transparent reporting and risk of bias in study design has never been systematically appraised. Therefore, through collaboration between a group of clinicians and data scientists with appropriate content expertise, we will perform a systematic review of papers published between January 2021 and December 2023 containing artificial intelligence prognostic models in AP. To systematically assess these studies, the authors will leverage the CHARMS checklist, PROBAST tool for risk of bias assessment, and the most current version of the TRIPOD-AI.

RESUMEN
Obesity is a risk factor for pancreatic ductal adenocarcinoma (PDAC), a deadly disease with limited preventive strategies. Lifestyle interventions to decrease obesity represent a potential approach to prevent obesity-associated PDAC. Here, we examined whether decreasing obesity through physical activity (PA) and/or dietary changes could decrease inflammation in humans and prevent obesity-associated PDAC in mice. Comparison of circulating inflammatory-associated cytokines in subjects (overweight and obese) before and after a PA intervention revealed PA lowered systemic inflammatory cytokines. Mice with pancreatic-specific inducible KrasG12D expression were exposed to PA and/or dietary interventions during and after obesity-associated cancer initiation. In mice with concurrent diet-induced obesity (DIO) and KrasG12D expression, the PA intervention led to lower weight gain, suppressed systemic inflammation, delayed tumor progression, and decreased pro-inflammatory signals in the adipose tissue. However, these benefits were not as evident when obesity preceded pancreatic KrasG12D expression. Combining PA with diet-induced weight loss (DI-WL) delayed obesity-associated PDAC progression in the genetically engineered mouse model, but neither PA alone nor combined with DI-WL or chemotherapy prevented PDAC tumor growth in orthotopic PDAC models regardless of obesity status. PA led to upregulation of IL-15ra in adipose tissue. Adipose-specific overexpression of IL-15 slowed PDAC growth but only in non-obese mice. Overall, our study suggests that PA alone or combined with DI-WL can reduce inflammation and delay obesity-associated PDAC development or progression. Lifestyle interventions that prevent or manage obesity or therapies that target weight loss-related molecular pathways could prevent progression of PDAC.
RESUMEN
PURPOSE: Rising obesity and type 2 diabetes mellitus (T2DM) rates can be mitigated by various strategies, with a 10% total body weight loss (TBWL) threshold often required for T2DM remission. T2DM remission rates after bariatric surgery like Roux-en-Y gastric bypass (RYGB) are well established; endoscopic sleeve gastroplasty (ESG) is a less invasive option that averages 15% TBWL and allows for T2DM remission. This study explores the DiaRem (Diabetes Remission post-RYGB) score's ability to predict T2DM remission 1-year post-ESG. MATERIALS AND METHODS: We conducted a retrospective cohort study on 39 individuals with T2DM who underwent ESG. Age, utilization of diabetes medications, insulin administration, and hemoglobin A1c levels were used to calculate the DiaRem score. The area under the receiver operating characteristic curve (AUC) was employed to evaluate the discriminative ability of DiaRem in distinguishing diabetes remission. RESULTS: Among the 39 patients with a median hemoglobin A1c of 6.7, 12.8% required insulin, and 43.6% used diabetes medication. At 1-year post-ESG, 69.2% of patients experienced diabetes remission with a median %TWBL of 12.7. The DiaRem score's ability to detect diabetes resolution for ESG patients had a sensitivity of 100% and a specificity of 58.3%, at the optimal cutoff value of 10. The AUC was 0.779 (95% CI 0.546-0.959). CONCLUSION: Our study demonstrated the DiaRem score's predictive value for T2DM remission post-ESG, highlighting its utility in clinical decision-making for ESG-related outcomes. Further investigation is needed to identify alternative indicators that may enhance predictive accuracy, thus refining personalized decision-making for this patient group.
RESUMEN
INTRODUCTION: The use of social media as a medical information tool parallels rising obesity rates. TikTok, the popular video-sharing platform, contains nearly 99,000 videos hashtagged "weightloss." Prior studies have analyzed the quality of medical information on TikTok in other areas of medicine. However, the quality of videos regarding weight loss procedures has not yet been determined. METHODS: Hashtags encompassing three weight loss modalities were searched using TikTok's algorithm. The first 50 videos meeting inclusion criteria for each modality were considered. Two independent reviewers categorized videos and assessed their content quality using DISCERN. Quality scores and popularity were compared between videos sources, modalities, and content categories. RESULTS: Of 150 videos included, 20.7% were created by physicians versus 79.3% by non-physicians (p < 0.001). The average DISCERN score for physician-created content was significantly higher than that of non-physicians (p < 0.001), despite significantly less popularity (p < 0.002). The 50 most popular videos had significantly lower DISCERN scores than the 50 least popular (p < 0.02). The average DISCERN score for endoscopic sleeve gastroplasty (ESG) videos were significantly higher than videos related to Roux-en-Y gastric bypass (RYGB) and vertical sleeve gastrectomy (VSG) (p < 0.001). VSG-related videos were significantly more popular than RYGB- and ESG-related videos (p < 0.001 and p < 0.001). Finally, educational videos had significantly higher DISCERN scores than weight loss transformation and personal experience videos (p < 0.001). CONCLUSION: Videos on TikTok related to weight loss procedures are poor, and greater popularity trends with lower quality. Assessment of content can encourage viewers to seek better information and allow providers to improve patient information tools.

OBJECTIVE: The use of social media applications to disseminate information has substantially risen in recent decades. Spine and back pain-related hashtags have garnered several billion views on TikTok. As such, these videos, which share experiences, offer entertainment, and educate users about spinal surgery, have become increasingly influential. Herein, we assess the quality of spine surgery content TikTok from providers and patients. METHODS: Fifty hashtags encompassing spine surgery ("#spinalfusion," "#scoliosissurgery," and "#spinaldecompression") were searched using TikTok's algorithm and included. Two independent reviewers rated the quality of each video via the DISCERN questionnaire. Video metadata (likes, shares, comments, views, length) were all collected; type of content creator (musculoskeletal, layperson) and content category (educational, patient experience, entertainment) were determined. RESULTS: The overall DISCERN score was, on average, 24.4. #Spinalfusion videos demonstrated greater engagement, higher average likes (p = 0.02), and more comments (p < 0.001) compared to #spinaldecompression and #scoliosissurgery. #Spinaldecompression had the highest DISCERN score (p < 0.001), likely explained by the higher percentage of videos that were educational (p < 0.001) and created by musculoskeletal (MSK) professionals (p < 0.001). Compared to laypersons, MSK professionals had significantly higher quality videos (p < 0.001). Similarly, the educational category demonstrated higher quality videos (p < 0.001). Video interaction trended lower with MSK videos and educational videos had the lowest interaction of the content categories (likes: p = 0.023, comments: p = 0.005). CONCLUSION: The quality of spine surgery videos on TikTok is low. As the influence of the new social media landscape governs how the average person consumes information, MSK providers should participate in disseminating high-quality content.
RESUMEN
BACKGROUND & AIMS: Obesity is a risk factor for pancreatic ductal adenocarcinoma (PDAC), a deadly disease with limited preventive strategies. Lifestyle interventions to decrease obesity might prevent obesity-associated PDAC. Here, we examined whether decreasing obesity by increased physical activity (PA) and/or dietary changes would decrease inflammation in humans and prevent PDAC in mice. METHODS: Circulating inflammatory-associated cytokines of overweight and obese subjects before and after a PA intervention were compared. PDAC pre-clinical models were exposed to PA and/or dietary interventions after obesity-associated cancer initiation. Body composition, tumor progression, growth, fibrosis, inflammation, and transcriptomic changes in the adipose tissue were evaluated. RESULTS: PA decreased the levels of systemic inflammatory cytokines in overweight and obese subjects. PDAC mice on a diet-induced obesity (DIO) and PA intervention, had delayed weight gain, decreased systemic inflammation, lower grade pancreatic intraepithelial neoplasia lesions, reduced PDAC incidence, and increased anti-inflammatory signals in the adipose tissue compared to controls. PA had additional cancer prevention benefits when combined with a non-obesogenic diet after DIO. However, weight loss through PA alone or combined with a dietary intervention did not prevent tumor growth in an orthotopic PDAC model. Adipose-specific targeting of interleukin (IL)-15, an anti-inflammatory cytokine induced by PA in the adipose tissue, slowed PDAC growth. CONCLUSIONS: PA alone or combined with diet-induced weight loss delayed the progression of PDAC and reduced systemic and adipose inflammatory signals. Therefore, obesity management via dietary interventions and/or PA, or modulating weight loss related pathways could prevent obesity-associated PDAC in high-risk obese individuals.
RESUMEN
BACKGROUND: Multisystem organ failure (MSOF) is the most important determinant of mortality in acute pancreatitis (AP). Obesity and alcoholic etiology have been examined as potential risk factors for MSOF, but prior studies have not adequately elucidated their independent effects on the risk of MSOF. OBJECTIVE: We aimed to determine the adjusted effects of body mass index (BMI) and alcoholic etiology on the risk of MSOF in subjects with AP. METHODS: A prospective observational study of 22 centers from 10 countries was conducted. Patients admitted to an APPRENTICE consortium center with AP between August 2015 and January 2018 were enrolled. Multivariable logistic regression was used to estimate the adjusted effects of BMI, etiology, and other relevant covariates on the risk of MSOF. Models were stratified by sex. RESULTS: Among 1544 AP subjects, there was a sex-dependent association between BMI and the risk of MSOF. Increasing BMI was associated with increased odds of MSOF in males (OR 1.10, 95% confidence interval [CI] 1.04-1.15) but not in females (OR 0.98, 95% CI 0.90-1.1). Male subjects with AP, whose BMIs were 30-34 and >35 kg/m2 , had odds ratios of 3.78 (95% CI 1.62-8.83) and 3.44 (95% CI 1.08-9.99), respectively. In females, neither higher grades of obesity nor increasing age increased the risk of MSOF. Alcoholic etiology was independently associated with increased odds of MSOF compared with non-alcohol etiologies (OR 4.17, 95% CI 2.16-8.05). CONCLUSION: Patients with alcoholic etiology and obese men (but not women) are at substantially increased risk of MSOF in AP.

OBJECTIVES: We describe the methodology of Post-Acute Pancreatitis Pancreatic Exocrine Insufficiency (PAPPEI), a prospective, observational, multicenter cohort study. The objectives of PAPPEI are to estimate the incidence rate of post-acute pancreatitis (AP) pancreatic exocrine insufficiency (PEI), define factors that determine the development of post-AP PEI, and evaluate the impact of post-AP PEI on nutritional status and quality of life. METHODS: Enrollment started in June 2017 in 3 expert academic centers in the United States. Data were collected during hospitalization (baseline) at 3 and 12 months after enrollment. Fecal elastase-1 was used to assess PEI. Study questionnaires are completed by patient interview and review of electronic medical records. Blood is obtained to evaluate vitamin deficiencies and nutritional markers. RESULTS: As of August 2020, 77 subjects have completed the baseline evaluation. The median age was 58 years (interquartile range, 39-67 years), 38% were male, and 90% were white. The etiology of AP was biliary in 39 subjects (51%), and 51 subjects (66%) had mild AP. Three- and 12-month follow-up data have been collected in 29 and 13 subjects, respectively. CONCLUSION: The PAPPEI study aims to expand our understanding of post-AP PEI incidence, including its impact on nutritional status and quality of life.

BACKGROUND: Inability to advance to an oral diet, or oral feeding intolerance, is a common complication in patients with acute pancreatitis associated with worse clinical outcomes. The factors related to oral feeding intolerance are not well studied. OBJECTIVE: We aimed to determine the incidence and risk factors of oral feeding intolerance in acute pancreatitis. METHODS: Patients were prospectively enrolled in the Acute Pancreatitis Patient Registry to Examine Novel Therapies in Clinical Experience, an international acute pancreatitis registry, between 2015 and 2018. Oral feeding intolerance was defined as worsening abdominal pain and/or vomiting after resumption of oral diet. The timing of the initial feeding attempt was stratified based on the day of hospitalization. Multivariable logistic regression was performed to assess for independent risk factors/predictors of oral feeding intolerance. RESULTS: Of 1233 acute pancreatitis patients included in the study, 160 (13%) experienced oral feeding intolerance. The incidence of oral feeding intolerance was similar irrespective of the timing of the initial feeding attempt relative to hospital admission day (p = 0.41). Patients with oral feeding intolerance were more likely to be younger (45 vs. 50 years of age), men (61% vs. 49%), and active alcohol users (44% vs. 36%). They also had higher blood urea nitrogen (20 vs. 15 mg/dl; p < 0.001) and hematocrit levels (41.7% vs. 40.5%; p = 0.017) on admission; were more likely to have a nonbiliary acute pancreatitis etiology (69% vs. 51%), systemic inflammatory response syndrome of 2 or greater on admission (49% vs. 35%) and at 48 h (50% vs. 26%), develop pancreatic necrosis (29% vs. 13%), moderate to severe acute pancreatitis (41% vs. 24%), and have a longer hospital stay (10 vs. 6 days; all p < 0.04). The adjusted analysis showed that systemic inflammatory response syndrome of 2 or greater at 48 h (odds ratio 3.10; 95% confidence interval 1.83-5.25) and a nonbiliary acute pancreatitis etiology (odds ratio 1.65; 95% confidence interval 1.01-2.69) were independent risk factors for oral feeding intolerance. CONCLUSION: Oral feeding intolerance occurs in 13% of acute pancreatitis patients and is independently associated with systemic inflammatory response syndrome at 48 h and a nonbiliary etiology.

Pancreatic cancer has a high mortality rate with minimal proven interventions. Intraductal Papillary Mucinous Neoplasms (IPMNs) are known precursor lesions for pancreatic cancer. Identification of pancreatic cysts has improved from advances in abdominal imaging. Despite multiple revisions of the international consensus recommendations and various guidelines by other major societies, successful risk stratification of the malignant potential of mucinous pancreatic cysts remains challenging. Specifically, detection and accurate classification of advanced neoplasia (high-grade dysplasia and/or adenocarcinoma) in IPMNs is suboptimal with current diagnostic strategies. Development of interventional techniques utilizing endoscopic ultrasound include - through-the-needle microforceps biopsy, next-generation or whole genome molecular analysis of cyst fluid, and needle-based confocal laser endomicroscopy. These techniques suffer from a series of limitations in technical success, diagnostic yield, and clinical feasibility, but a combination approach may offer a solution that optimizes their cyst evaluation and risk stratification. Assessment and comparison of these techniques is restricted by lack of adequate surgical specimens for testing of diagnostic accuracy, resulting in a possible sample bias. Additional large-scale multicenter studies are needed to accumulate evidence for the utility and feasibility of their translation into clinical practice. Great strides have been made in pancreatic cyst evaluation, but further research is required to improve diagnostic accuracy and clinical management of IPMNs.

INTRODUCTION: Studies evaluating the natural history of exocrine pancreatic dysfunction (EPD) after acute pancreatitis (AP) are sparse. This study aims to assess incidence and predictors of weight loss and gastrointestinal (GI) symptoms suggestive of EPD 12 months after an AP episode. METHODS: Patients enrolled in the Pancreatitis-associated Risk of Organ Failure Study at the time of an AP episode were included. Weight and GI symptom data were prospectively collected by self-report at enrollment and at 3- and 12-month (windows 2-7 and 8-20) telephone follow-ups. Multivariable logistic regression was used to assess factors associated with ≥10% total body weight loss (EPD surrogate) at 12 months. A generalized estimating equation was used to measure each factor's population effect (in pounds) over 12 months after AP. RESULTS: Follow-up at 12 months in 186 patients (median age = 54 years, 46% men, 45% biliary, 65% first AP attack) revealed weight loss ≥10% from baseline, occurring in 44 patients (24%). Risk of weight loss increased with higher baseline body mass index, previous diagnosis of diabetes mellitus, and worsening AP severity (all P < 0.010). GI symptoms were reported in 13/31 (42%) patients at 12 months. AP severity was independently associated with ≥10% weight loss at 12 months. Over 12 months, men lost more weight than women (average 9.5 lbs); patients with severe AP lost, on average, 14 lbs. DISCUSSION: Weight loss after AP occurs in one-quarter of patients and is associated with AP severity. EPD incidence after AP is likely underappreciated. Further work is needed to assess EPD and potential for pancreatic enzyme supplementation.
