Review
While typically considered a pulmonary disease, cystic fibrosis patients develop significant nutritional complications and comorbidities, especially those who are pancreatic insufficient. Clinicians must have a high suspicion for cystic fibrosis among patients with clinical symptoms of pancreatic insufficiency, and pancreatic enzymatic replacement therapy (PERT) must be urgently initiated. PERT presents a myriad of considerations for patients and their supporting dieticians and clinicians, including types of administration, therapy failures, and complications.

Review
Obesity has become a major medical and public health problem worldwide. Recent studies have shown that obesity is a chronic disease that is associated with many diseases, such as gallstone disease, acute pancreatitis, fatty liver, and digestive cancer. Obesity is also a risk factor for the formation of cholesterol gallstones. Clinical and epidemiological studies have suggested that obesity is positively associated with the risk of gallbladder cancer. Obesity may modulate the lipid and endogenous hormones metabolism, affect gallbladder motility, increase the risk of gallstones, and increased the risk of gallbladder cancer. In addition, obesity has been considered a risk factor for pancreatic diseases, including pancreatitis and pancreatic cancer. Obese patients develop systemic and local complications of acute pancreatitis more frequently. Several epidemiologic studies have suggested an association of pancreatic cancer with high body mass and lack of physical activity. This study reviewed the literature on obesity and pancreatobiliary disease in terms of epidemiology and mechanism.

Review
MR imaging can be optimized to evaluate a spectrum of pancreatic disorders with advanced sequences aimed to provide quantitative results and increase MR diagnostic capabilities. The pancreas remains a challenging organ to image because of its small size and location deep within the body. Besides its anatomic limitations, pancreatic pathology can be difficult to identify in the early stages. For example, subtle changes in ductal anatomy and parenchymal composition seen in early chronic pancreatitis are imperceptible with other modalities, such as computed tomography. This article reviews the application of MR imaging techniques and emerging MR sequences used in pancreas imaging.

Review
Gene regulatory factors that govern the expression of heritable information come in an array of flavors, chiefly with transcription factors, the proteins which bind to regions of specific genes and modulate gene transcription, subsequently altering cellular function. PAX transcription factors are sequence-specific DNA-binding proteins exerting its regulatory activity in many tissues. Notably, three members of the PAX family namely PAX2, PAX4 and PAX6 have emerged as crucial players at multiple steps of pancreatic development and differentiation and also play a pivotal role in the regulation of pancreatic islet hormones synthesis and secretion. Providing a comprehensive outline of these transcription factors and their primordial and divergent roles in the pancreas is far-reaching in contemporary diabetes research. Accordingly, this review furnishes an outline of the role of pancreatic specific PAX regulators in the development of the pancreas and its associated disorders.

Review
Metabolic syndrome and its components such as obesity, hypertriglyceridemia, type-2 diabetes mellitus (DM-T2), and arterial hypertension are unequivocally serious problems for every society. This is especially true in economically developed countries where the imbalance in lifestyle between caloric intake and caloric output still gets greater and greater. This fact is not only a concern for the adult population but for children as well. However, metabolic syndrome does not only affect society and health in regards to cardiovascular diseases, it significantly concerns gastroenterology where it is classified as nonalcoholic fatty pancreas disease (NAFPD). The data gained from several trials show that the prevalence of NAFDP is 33% (95% CI 24-41%). When it comes to the diagnostic procedures concerning the presence of pancreatic fat, a whole spectrum of suitable methods are recommended. Probably, the most exact method is the use of magnetic resonance imaging. However, for common clinical practice, the abdominal sonographic examination based on the comparison of the pancreatic parenchymatous echogenity versus renal or hepatic echogenity is used. The clinical consequences of pancreatic steatosis and steatopancreatitis are significant. These diseases are connected with DM-T2 and insulin resistance. In recent years, changes of exocrine pancreatic function, particularly its decrease, have also been described. It is known that there is a close correlation between NAFPD and nonalcoholic hepatic steatosis and also with the increased thickness of aortic intima-media. There is also an important relationship between NAFPD and pancreatic carcinoma. Pancreatic steatosis, and especially its NAFPD form, is a serious state which can be treatable by the possible effective management of metabolic syndrome parameters, including obesity.

Review
Benign non-neoplastic solid lesions of the pancreas are comprised of several separate entities, with their diagnostic identification best performed in correlation with the radiographic and clinical features. These include all of the pancreatitides, intrapancreatic spleen, and a few other rare entities. Preoperative imaging may suggest the correct diagnosis, but occasionally the preoperative imaging findings may be misleading because they overlap with those of pancreatic neoplasms. Masses associated with typical pancreatitides are rarely sampled due to their distinct clinical picture and relative frequency; however, the uncommon variants of pancreatitis may also present as mass lesions mimicking malignancy. Herein, we will discuss the cytopathologic findings of several solid pancreatic lesions, including acute pancreatitis, chronic pancreatitis, autoimmune pancreatitis, paraduodenal or groove pancreatitis, and other mass lesions, such as intrapancreatic accessory spleen and abscess. The key cytological features, ancillary studies, and differential diagnoses will also be discussed.

Review
Pancreatic diseases, a serious threat to human health, have garnered considerable research interest, as they are associated with a high mortality rate. However, owing to the uncertain etiology and complex pathophysiology, the treatment of pancreatic diseases is a challenge for clinicians and researchers. Exosomes, carriers of intercellular communication signals, play an important role in the diagnosis and treatment of pancreatic diseases. Exosomes are involved in multiple stages of pancreatic disease development, including apoptosis, immune regulation, angiogenesis, cell migration, and cell proliferation. Thus, extensive alterations in the quantity and variety of exosomes may be indicative of abnormal biological behaviors of pancreatic cells. This phenomenon could be exploited for the development of exosomes as a new biomarker or target of new treatment strategies. Several studies have demonstrated the diagnostic and therapeutic effects of exosomes in cancer and inflammatory pancreatic diseases. Herein, we introduce the roles of exosomes in the diagnosis and treatment of pancreatic diseases and discuss directions for future research and perspectives of their applications.

Review
Per-oral pancreatoscopy (POP) is a pancreas-preserving modality that allows for targeted pancreatic duct interventions, particularly in cases where standard techniques fail. POP specifically has an emerging role in the diagnosis, risk stratification, and disease extent determination of main duct intraductal papillary mucinous neoplasms (IPMNs). It has also been successfully used for laser ablation of IPMNs in poor surgical candidates, lithotripsy for complex stone disease, and laser stricturoplasty. As experience with POP increases beyond select referral center practices, further studies validating POP efficacy with long-term follow-up will help clarify when POP-guided intervention is most beneficial in relation to surgical intervention.

The "Integrated Physiology of the Exocrine and Endocrine Compartments in Pancreatic Diseases" Workshop was a 1.5-day scientific conference at the National Institutes of Health (Bethesda, MD) that engaged clinical and basic science investigators interested in diseases of the pancreas. This report summarizes the workshop proceedings. The goal of the workshop was to forge connections and identify gaps in knowledge that could guide future research directions. Presentations were segregated into 6 major themes, including (a) Pancreas Anatomy and Physiology; (b) Diabetes in the Setting of Exocrine Disease; (c) Metabolic Influences on the Exocrine Pancreas; (d) Genetic Drivers of Pancreatic Diseases; (e) Tools for Integrated Pancreatic Analysis; and (f) Implications of Exocrine-Endocrine Crosstalk. For each theme, there were multiple presentations followed by panel discussions on specific topics relevant to each area of research; these are summarized herein. Significantly, the discussions resulted in the identification of research gaps and opportunities for the field to address. In general, it was concluded that as a pancreas research community, we must more thoughtfully integrate our current knowledge of the normal physiology as well as the disease mechanisms that underlie endocrine and exocrine disorders so that there is a better understanding of the interplay between these compartments.
