Systemic air embolism associated with endoscopic retrograde cholangiopancreatography: A case report

BACKGROUND Endoscopic retrograde cholangiopancreatography (ERCP) is a key procedure for diagnosing and treating biliary and pancreatic disorders. Although effective, it carries risks, including rare but severe complications such as air embolism. CASE SUMMARY We report a case of a 58-year-old man who developed extensive air embolism during ERCP. He previously underwent a Whipple procedure and experienced a sudden drop in vital signs and loss of consciousness. Immediate intervention with hyperbaric oxygen therapy and supportive care led to gradual recovery. Imaging confirmed widespread air embolism, which resolved with continued treatment. CONCLUSION Air embolism is a rare, critical complication of ERCP, especially in patients with prior surgery such as pancreaticoduodenectomy. Early detection and prompt treatment, including hyperbaric oxygen therapy, are crucial for favorable outcomes.

Deep Learning Reconstruction for Enhanced Resolution and Image Quality in Breath-Hold MRCP: A Preliminary Study

Objective This preliminary study aims to assess the image quality of enhanced-resolution deep learning reconstruction (ER-DLR) in magnetic resonance cholangiopancreatography (MRCP) and compare it with non-ER-DLR MRCP images. Methods Our retrospective study incorporated 34 patients diagnosed with biliary and pancreatic disorders. We obtained MRCP images using a single breath-hold MRCP on a 3T MRI system. We reconstructed MRCP images with ER-DLR (matrix = 768 × 960) and without ER-DLR (matrix = 256 × 320). Quantitative evaluation involved measuring the signal-to-noise ratio (SNR), contrast, contrast-to-noise ratio (CNR) between the common bile duct and periductal tissues, and slope. Two radiologists independently scored image noise, contrast, artifacts, sharpness, and overall image quality for the 2 image types using a 4-point scale. Results are expressed as median and interquartile range (IQR), and we compared quantitative and qualitative scores employing the Wilcoxon test. Results In quantitative analyses, ER-DLR significantly improved SNR (21.08 [IQR: 14.85, 31.5] vs 15.07 [IQR: 9.57, 25.23], P < 0.001), CNR (19.29 [IQR: 13.87, 24.98] vs 11.23 [IQR: 8.98, 15.74], P < 0.001), contrast (0.96 [IQR: 0.94, 0.97] vs 0.9 [IQR: 0.87, 0.92], P < 0.001), and slope of MRCP (0.62 [IQR: 0.56, 0.66] vs 0.49 [IQR: 0.45, 0.53], P < 0.001). The qualitative evaluation demonstrated significant improvements in the perceived noise (P < 0.001), contrast (P = 0.013), sharpness (P < 0.001), and overall image quality (P < 0.001). Conclusions ER-DLR markedly increased the resolution, SNR, and CNR of breath-hold-MRCP compared to cases without ER-DLR.

Revisiting the markers interleukin-6 and glucagon-like peptide-1 for targeting low-grade inflammation in type 2 diabetes: a meta-analysis and our lab experience.

Type 2 diabetes (T2DM) manifests as pancreatic disorder as a consequence of low-grade systemic inflammation, attributed to upregulated levels of interleukin-6 (IL-6). This in turn is associated with a reduced incretin effect with lower circulatory GLP-1 levels. Therefore, its important to monitor the circulating IL-6 and GLP-1 levels for better management and outcomes in T2DM patients. Limited studies being available in literature on circulating concentrations of GLP-1 and IL-6 in T2DM patients, a meta-analysis was conducted by identifying 1558 studies from 3 databases. As per inclusion and exclusion criteria, the studies were screened for the 2-markers.Forest plots were drawn for standardized mean differences and median values were deduced from the datasets. In parallel, analysis was conducted to ascertain the expression levels of the markers by ELISA (n = 52 T2DM patients) in real time. The meta-analysis showed a significant (p < 0.01) standardized mean difference of 3.82 and 1.04 for IL-6 and GLP-1 respectively. The median values obtained from analysis for IL-6 were 26.50 pg/ml which were higher than the controls downregulated levels of GLP-1(8.77 pg/ml) were noted. The above findings are corroborated by the results of our experimental analysis with IL-6 concentrations at 11.603pg/ml and GLP-1 at 13.05pg/ml. The study highlights that systemic concentrations of IL-6 and GLP-1 correspond to a persistent low-grade inflammation and decreased incretin effect in T2DM patients which manifest as pancreatic β-cell dysfunction. The expression of the markers is inversely correlated and monitoring their levels is clinically important for targeting them through their potential antagonists thus reducing the risk of complications, thereby improving the quality of life of the patients.

Role of Sphingosine-1-Phosphate Signaling Pathway in Pancreatic Diseases.

Sphingosine-1-phosphate (S1P) is a sphingolipid metabolic product produced via the phosphorylation of sphingosine by sphingosine kinases (SPHKs), serving as a powerful modulator of various cellular processes through its interaction with S1P receptors (S1PRs). Currently, this incompletely understood mechanism in pancreatic diseases including pancreatitis and pancreatic cancer, largely limits therapeutic options for these disorders. Recent evidence indicates that S1P significantly contributes to pancreatic diseases by modulating inflammation, promoting pyroptosis in pancreatic acinar cells, regulating the activation of pancreatic stellate cells, and affecting organelle functions in pancreatic cancer cells. Nevertheless, no review has encapsulated these advancements. Thus, this review compiles information about the involvement of S1P signaling in exocrine pancreatic disorders, including acute pancreatitis, chronic pancreatitis, and pancreatic cancer, as well as prospective treatment strategies to target S1P signaling for these conditions. The insights presented here possess the potential to offer valuable guidance for the implementation of therapies targeting S1P signaling in various pancreatic diseases.

Spot Urine Sodium to Potassium Ratio as a Tool to Assess Severity and Mortality among Patients with Decompensated Cirrhosis having Ascites

Background: Decompensated cirrhosis of liver is considered as a systemic disease affecting the functions of several other organs. Renal function is an independent prognostic factor for patients with decompensated cirrhosis, but assessing renal function through glomerular filtration rate are not convenient, especially for routine use. Previous study found that spot urinary sodium to potassium ratio (UNa/K) was associated with renal dysfunction which influences the severity and outcome in decompensated cirrhosis of liver patients having ascites. Aims and objectives: The present study was aimed to determine the relation of the ratio of sodium to potassium in randomly collected urine samples with severity of disease and mortality in decompensated cirrhosis having ascites. Materials and Methods: This longitudinal study was conducted at the Department of Gastrointestinal, Hepatobiliary and Pancreatic Disorders, BIRDEM General Hospital, Shahbagh, Dhaka, Bangladesh, from July, 2019 to August, 202l. A total of 150 patients with a confirmed diagnosis of decompensated cirrhosis with ascites were enrolled in this study. A detailed history and thorough clinical examination were carried out in each patient, along with relevant investigations. Data collection was done through a structured questionnaire. Data were analyzed using the statistical software SPSS 23. Results: Age of the patients was 59.0±12.91 (mean±SD) years, male predominance was observed (52%). The UNa/K ratio was 4.24±3.25 (mean±SD) with a range of 0.42 to 18.46. Diagnostic accuracy of UNa/K ratio in the detection of severity and mortality was estimated by the receiver operating characteristic (ROC) curve. The AUC of UNa/K ratio was 0.608 and 0.640 for severity and mortality respectively. Sensitivity, specificity, PPV and NPV at cut-off 2.55 were 50.0, 66.0, 42.4 and 72.5; at 2.65 were 54.0, 66.0, 44.3, and 74.2; at 2.87 were 58.0, 62.0, 43.3, and 74.7; at 3.21 were 58.0, 58.0, 40.8, and 73.4 respectively for severity score (MELD). Patients with UNa+/K+ less than 2.87 or equal, had a significantly higher MELD score category (p= 0.02). At 3 months follow-up, 24.7% mortality was observed. Sensitivity, specificity, PPV and NPV at cut-off 1.62 were 51.4, 85.8, 54.3 and 84.3; at 1.79 were 54.1, 79.7, 46.5 and 84.1; at 1.83 were 59.5, 77.0, 45.8 and 85.3; at 2.87 were 58.0, 62.0, 43.3, and 74.7 respectively for mortality. The UNa/K ratio was statistically low among the patients who didn’t survive (p&lt;.05). Conclusion: This study revealed that decreased ratio of spot urinary sodium to potassium was associated with the severity and mortality among decompensated cirrhosis of liver patients with ascites.

This comprehensive review aims to elucidate the biological intricacies of autophagy and its pivotal roles within two extensively researched pancreatic diseases, namely pancreatitis and pancreatic cancer, drawing upon recent scholarly contributions. The discussion will delve into the nuanced mechanisms underlying autophagy's involvement in these diseases, shedding light on its potential as a therapeutic target. Furthermore, the review will explore cutting-edge therapeutic interventions leveraging autophagy regulation for managing pancreatitis and pancreatic cancer. Through this analysis, we endeavor to offer novel insights into the pathophysiology of pancreatic disorders and contribute to the development of innovative therapeutic modalities in this challenging clinical domain.

Data privacy-aware machine learning approach in pancreatic cancer diagnosis

ProblemPancreatic ductal adenocarcinoma (PDAC) is considered a highly lethal cancer due to its advanced stage diagnosis. The five-year survival rate after diagnosis is less than 10%. However, if diagnosed early, the five-year survival rate can reach up to 70%. Early diagnosis of PDAC can aid treatment and improve survival rates by taking necessary precautions. The challenge is to develop a reliable, data privacy-aware machine learning approach that can accurately diagnose pancreatic cancer with biomarkers.AimThe study aims to diagnose a patient’s pancreatic cancer while ensuring the confidentiality of patient records. In addition, the study aims to guide researchers and clinicians in developing innovative methods for diagnosing pancreatic cancer.MethodsMachine learning, a branch of artificial intelligence, can identify patterns by analyzing large datasets. The study pre-processed a dataset containing urine biomarkers with operations such as filling in missing values, cleaning outliers, and feature selection. The data was encrypted using the Fernet encryption algorithm to ensure confidentiality. Ten separate machine learning models were applied to predict individuals with PDAC. Performance metrics such as F1 score, recall, precision, and accuracy were used in the modeling process.ResultsAmong the 590 clinical records analyzed, 199 (33.7%) belonged to patients with pancreatic cancer, 208 (35.3%) to patients with non-cancerous pancreatic disorders (such as benign hepatobiliary disease), and 183 (31%) to healthy individuals. The LGBM algorithm showed the highest efficiency by achieving an accuracy of 98.8%. The accuracy of the other algorithms ranged from 98 to 86%. In order to understand which features are more critical and which data the model is based on, the analysis found that the features “plasma_CA19_9”, REG1A, TFF1, and LYVE1 have high importance levels. The LIME analysis also analyzed which features of the model are important in the decision-making process.ConclusionsThis research outlines a data privacy-aware machine learning tool for predicting PDAC. The results show that a promising approach can be presented for clinical application. Future research should expand the dataset and focus on validation by applying it to various populations.

New Insights into Chronic Pancreatitis: Potential Mechanisms Related to Probiotics.

Chronic pancreatitis is a progressive fibroinflammatory disorder with no currently satisfactory treatment. Emerging evidence suggests an association between gut microbial dysbiosis and chronic pancreatitis. Although direct causative evidence is lacking, it is hypothesized that the gut microbiota may play a pivotal role in modulating pancreatic function via the gut-pancreas axis. Thus, modulating the gut microbiota through the administration of probiotics or prebiotics may alleviate pancreatic disorders. In this review, we first propose the potential mechanisms by which specific probiotics or prebiotics may ameliorate chronic pancreatitis, including the alleviation of small intestinal bacterial overgrowth (SIBO), the facilitation of short-chain fatty acids' (SCFAs) production, and the activation of glucagon-like peptide-1 receptors (GLP-1Rs) in the pancreas. Since there are currently no probiotics or prebiotics used for the treatment of chronic pancreatitis, we discuss research in other disease models that have used probiotics or prebiotics to modulate pancreatic endocrine and exocrine functions and prevent pancreatic fibrosis. This provides indirect evidence for their potential application in the treatment of chronic pancreatitis. We anticipate that this research will stimulate further investigation into the gut-pancreas axis and the potential therapeutic value of probiotics and prebiotics in chronic pancreatitis.

Relationship Between Gut Microbiota and Pancreatitis: A Systematic Review

Background and Aims: The human gastrointestinal system hosts a rich and diverse microbial community, surpassing a staggering 10[ 14 ] bacteria, collectively harbouring more than 5,000,000 genes. The aim of this study is to carry out a systematic review of human studies in order to investigate the correlation between the gut microbiota and pancreatic disorders. Materials and Methods: To systematically compile relevant research between 2011 and 2022, a thorough exploration of the MEDLINE and EMBASE databases was executed. The initial search results, encompassing all identified studies, were meticulously scrutinised, including a comprehensive review of their reference lists to ensure the completeness of our search. Initially, our search strategy yielded a total of 114 items. Subsequent refinement involved the removal of 58 duplicate articles identified in both searches. Following a meticulous screening process involving title, abstract and keyword assessments, 36 studies progressed to the next phase of evaluation. However, this cohort underwent further scrutiny, leading to the exclusion of 11 studies categorised as reviews or case reports, 5 in languages other than English that have been published and 20 that did not investigate the microbiome. As a result, a focused set of 20 papers emerged for in-depth evaluation for eligibility. Results: The demographic profile of the patients revealed that nearly half were men, with an average age of 52 years (interquartile range of 44-56). The interquartile range further ranged from 45% to 52%, reflecting the distribution of ages within the group. Among the studies scrutinising acute pancreatitis, gallstones emerged as the predominant cause in 9 out of 15, while 7 studies focusing on chronic pancreatitis found no evidence of gallstones. Conclusion: This comprehensive, systematic investigation has furnished robust evidence substantiating the intricate connection between pancreatitis and the microbiota.

Potential Use of Human Mesenchymal Stem Cells (hMSCs) in Pancreatic Damage/Cancer

Pancreatic damage and pancreatic cancer pose significant challenges due to their complex pathogenesis, limited treatment options, and poor prognosis. In recent years, the potential use of human Mesenchymal Stem Cells (hMSCs) has been explored to address these complex pancreatic conditions and develop novel therapeutics. hMSCs, known for their regenerative and immunomodulatory properties, offer a novel therapeutic avenue for repairing damaged tissues and possibly inhibiting cancer progression. This communication discusses current research findings on the application of hMSCs in pancreatic damage and cancer treatment while evaluating hMSC-mediated gene therapy in pancreatic disorders. Moreover, the challenges and considerations associated with hMSC-based therapies and the potential best therapeutic approaches are discussed. Furthermore, the current scientific evidence regarding hMSCs in revolutionizing the management of pancreatic damage and cancer, offering future perspectives for improved therapeutic strategies for patients facing these daunting conditions, is critically discussed.

Pancreatic pseudotumor due to peripancreatic lymphadenitis: case report and literature review

The pancreas has exocrine and endocrine glandular tissue, the latter accounting for only 1-2% of the gland. Pancreatic disorders are common but difficult to diagnose due to their anatomical location and vague symptoms. Pancreatic pseudotumors are enlarged pancreas without neoplasia and can be mistakenly diagnosed as malignant, complicating treatment. One study demonstrated that 9.2% of pancreatic resections suspected of malignancy were benign. In the clinical case presented, a 35-year-old male patient presented with severe abdominal pain, jaundice, weight loss, as well as fever, nausea, and vomiting. Laboratory tests showed significant changes in liver enzymes, bilirubin, and blood count. The differential diagnosis included lymphoma, tuberculosis, and other pathologies. Laparotomy revealed peripancreatic lymph nodes with caseous necrosis, which were confirmed as tuberculosis. Pancreatic tuberculosis is rare and can be confused with neoplasms due to similar symptoms. Accurate diagnosis requires a high degree of suspicion and methods such as image-guided biopsy. Treatment involves the use of tuberculostatics. In endemic regions, tuberculosis should always be considered in cases of peripancreatic lesions.

Understanding pancreatic disorders: Acute and chronic pancreatitis, pancreatic cancer and diabetes: A mini-review on a few of the most common pancreatic disorders

This mini-review provides an overview of pancreatic disorders, including acute and chronic pancreatitis, pancreatic cancer, and diabetes. The pancreas plays a crucial role in the digestive and endocrine systems of the body, producing enzymes that aid digestion and hormones that regulate blood sugar levels. Acute pancreatitis is a sudden and severe inflammation of the pancreas, often caused by gallstones or excessive alcohol consumption, and requires hospitalization, pain management, and intravenous fluids to support the pancreas. Chronic pancreatitis is a long-term inflammation of the pancreas that may lead to permanent damage and impairment of digestive function. Pancreatic cancer is a malignant tumor that forms in the pancreas and is often difficult to detect and diagnose in its early stages. Treatment for pancreatic cancer may include surgery, chemotherapy, and radiation therapy, depending on the type and stage of the cancer. Diabetes is a metabolic disorder that affects the body’s ability to produce or use insulin, and there are two main types of diabetes: type 1 and type 2. Type 1 diabetes is usually diagnosed in children and young adults and requires lifelong insulin therapy, while type 2 diabetes can often be managed with lifestyle modifications and medication.

Efficacy and Safety of GLP-1 Medicines for Type 2 Diabetes and Obesity.

The development of glucagon-like peptide 1 receptor agonists (GLP-1RA) for type 2 diabetes and obesity was followed by data establishing the cardiorenal benefits of GLP-1RA in select patient populations. In ongoing trials investigators are interrogating the efficacy of these agents for new indications, including metabolic liver disease, peripheral artery disease, Parkinson disease, and Alzheimer disease. The success of GLP-1-based medicines has spurred the development of new molecular entities and combinations with unique pharmacokinetic and pharmacodynamic profiles, exemplified by tirzepatide, a GIP-GLP-1 receptor coagonist. Simultaneously, investigational molecules such as maritide block the GIP and activate the GLP-1 receptor, whereas retatrutide and survodutide enable simultaneous activation of the glucagon and GLP-1 receptors. Here I highlight evidence establishing the efficacy of GLP-1-based medicines, while discussing data that inform safety, focusing on muscle strength, bone density and fractures, exercise capacity, gastrointestinal motility, retained gastric contents and anesthesia, pancreatic and biliary tract disorders, and the risk of cancer. Rapid progress in development of highly efficacious GLP-1 medicines, and anticipated differentiation of newer agents in subsets of metabolic disorders, will provide greater opportunities for use of personalized medicine approaches to improve the health of people living with cardiometabolic disorders.

The Pivotal Role of Macrophages in the Pathogenesis of Pancreatic Diseases.

The pancreas is an organ with both exocrine and endocrine functions, comprising a highly organized and complex tissue microenvironment composed of diverse cellular and non-cellular components. The impairment of microenvironmental homeostasis, mediated by the dysregulation of cell-to-cell crosstalk, can lead to pancreatic diseases such as pancreatitis, diabetes, and pancreatic cancer. Macrophages, key immune effector cells, can dynamically modulate their polarization status between pro-inflammatory (M1) and anti-inflammatory (M2) modes, critically influencing the homeostasis of the pancreatic microenvironment and thus playing a pivotal role in the pathogenesis of the pancreatic disease. This review aims to summarize current findings and provide detailed mechanistic insights into how alterations mediated by macrophage polarization contribute to the pathogenesis of pancreatic disorders. By analyzing current research comprehensively, this article endeavors to deepen our mechanistic understanding of regulatory molecules that affect macrophage polarity and the intricate crosstalk that regulates pancreatic function within the microenvironment, thereby facilitating the development of innovative therapeutic strategies that target perturbations in the pancreatic microenvironment.

Melatonin protects zebrafish pancreatic development and physiological rhythms from sodium propionate-induced disturbances via the hypothalamic-pituitary-thyroid axis.

The widespread use of sodium propionate as a preservative in food may affect public health. We aimed to assess the effects of sodium propionate on circadian rhythms and pancreatic development in zebrafish and the possible underlying mechanisms. In this experiment, we analyzed the relationship between circadian rhythms and pancreatic development and then revealed the role of the thyroid endocrine system in zebrafish. The results showed that sodium propionate interfered with the rhythmic behavior of zebrafish, and altered the expression of important rhythmic genes. Experimental data revealed that pancreatic morphology and developmental genes were altered after sodium propionate exposure. Additionally, thyroid hormone levels and key gene expression associated with the hypothalamic-pituitary-thyroid axis were significantly altered. Melatonin at a concentration of 1 μmol L-1, with a mild effect on zebrafish, observably alleviated sodium propionate-induced disturbances in circadian rhythms and pancreatic development, as well as regulating the thyroid system. Melatonin, while modulating the thyroid system, significantly alleviates sodium propionate-induced circadian rhythm disturbances and pancreatic developmental disorders. We further revealed the deleterious effects of sodium propionate as well as the potential therapeutic effects of melatonin on circadian rhythm, pancreatic development and the thyroid system. © 2024 Society of Chemical Industry.

The Importance of Microbiota and Fecal Microbiota Transplantation in Pancreatic Disorders.

The role of the intestinal microbiota in the diagnosis and treatment of pancreatic diseases is increasingly significant. Consequently, fecal microbiota transplantation (FMT) is emerging as a promising therapeutic avenue for various pancreatic disorders, including cancer, pancreatitis, and type 1 diabetes (T1D). This innovative procedure entails transferring gut microbiota from healthy donors to individuals affected by pancreatic ailments with the potential to restore intestinal balance and alleviate associated symptoms. FMT represents a pioneering approach to improve patient outcomes in pancreatic diseases, offering tailored treatments customized to individual microbiomes and specific conditions. Recent research highlights the therapeutic benefits of targeting the gut microbiota for personalized interventions in pancreatic disorders. However, a comprehensive understanding of the intricate interplay between gut microbiota and pancreatic physiology warrants further investigation. The necessity for additional studies and research endeavors remains crucial, especially in elucidating both adult and pediatric cases affected by pathological pancreatic conditions.

Pancreas Transplantation for the Treatment of Pancreatic Exocrine Disorders

Pancreas transplantation is mostly performed to cure diabetes mellitus. However, patients with chronic pancreatitis, cystic fibrosis, benign pancreatic tumors or patients with other exocrine disorders of the pancreas can also be candidates for a pancreas transplant in combination with a kidney, liver or lung or for a pancreas transplant alone. With improvement in surgical techniques and immunosuppressive therapy, pancreas transplant outcomes have improved significantly over the past decade. Mounting evidence supports pancreas transplantation for the treatment of exocrine disorders as an important therapeutic option to restore both endocrine and exocrine function of the pancreas. Patient and graft survival rates are similar to those for pancreas transplants in diabetic patients. A successful pancreas transplant is also more cost efficient and puts less burden on health care spending. However, the risk of immunosuppression and surgery should be carefully evaluated and discussed with the patient. In this review article, we discuss pancreas transplantation for pancreatic exocrine disorders: indications, other treatment options, and outcomes.

Evaluation of Imaging-Guided Peritoneal Biopsy in Diagnosis of Ascites of Unknown Origin

AbstractAscites is a common clinical problem, which can be a result of liver cirrhosis, neoplasm, tuberculous or pyogenic peritonitis, heart failure, nephrosis, and pancreatic disorders. This study aimed to evaluate the role of imaging-guided peritoneal biopsy in the diagnosis of ascites of unknown origin (ascites of local cause). Sixty-three patients with ascites of unknown etiology were included. Abdominal ultrasonography (US) with colored Duplex was performed, followed by laboratory investigations such as, ascitic fluid samples, magnetic resonance imaging, multislice computed tomography (CT), or PET/CT scan (if indicated). Imaging-guided peritoneal biopsy such as US-guided or CT-guided percutaneous peritoneal biopsy (in cases of failure of US-guided technique) of omentum or extravisceral masses was performed. Cytological and histopathological examinations of the tissue specimens were done by a single experienced pathologist. Other more invasive procedures (e.g., laparoscopy) were needed when the imaging-guided biopsy was not diagnostic. Fifty-four patients underwent US-guided biopsies, 48 patients were successfully diagnosed, and other 9 patients underwent CT-guided biopsies (not accessible by US-guided modality); laparoscopy was needed only in 6 patients. Malignant peritoneal pathology was found in 48 patients, while tuberculous peritonitis was diagnosed in 14 patients. Imaging-guided biopsies had perfect sensitivity (100%) and negative predictive value (100%) in differentiating neoplastic lesions. Percutaneous imaging-guided biopsy (US/CT guided) of the peritoneum, omenta, and mesentery has been established as a safe, simple, noninvasive, and well-tolerated procedure with high diagnostic accuracy. It can minimize further unnecessary invasive procedures such as laparoscopy.
