P-suPAR may reflect the inflammatory response after pancreatic surgery.

Background: Several different scoring systems have been developed to predict post-pancreatectomy complications. Currently used inflammatory markers are of only limited value in predicting complications after pancreatic surgery. Plasma soluble urokinase plasminogen activator receptor (P-suPAR) is a prognostic biomarker associated with different inflammatory conditions.

Long-term (10-year) outcomes and prognostic factors in resected intraductal papillary mucinous neoplasm tumors in Finland: A nationwide retrospective study.

Background: The degree of dysplasia is the most important prognostic factor for patients with resected intraductal papillary mucinous neoplasms. Intraductal papillary mucinous neoplasms are predominantly premalignant conditions; in most cases, surveillance is an adequate treatment. If worrisome features are present, surgery should be considered.

Osteoporosis and sarcopenia are common and insufficiently diagnosed among chronic pancreatitis patients.

Purpose: Chronic pancreatitis (CP) leads to diabetes and pancreatic exocrine insufficiency (PEI). PEI may lead to maldigestion and malnutrition, which may cause fat-soluble vitamin deficiency, sarcopenia and abnormal bone density. We aim to study the prevalence of osteoporosis, sarcopenia and vitamin deficiency among CP patients.

Plasma soluble urokinase-type plasminogen activator receptor (P-suPAR) in the diagnostics between malignant and non-malignant pancreatic lesions.

Background: Soluble urokinase-type plasminogen activator receptor (suPAR) is a biomarker elevated in several inflammatory conditions and cancers. It has recently been shown to be elevated in pancreatic ductal adenocarcinoma (PDAC). Plasma suPAR (P-suPAR) predicts the severity of the disease in first acute alcohol-induced pancreatitis (AAP) and ten-year mortality after recovery from first AAP.

Pancreatic Secretory Trypsin Inhibitor (SPINK1) Gene Mutation in Patients with Acute Alcohol Pancreatitis (AAP) Compared to Healthy Controls and Heavy Alcohol Users without Pancreatitis.

Only 3-5% of heavy alcohol users develop acute alcohol pancreatitis (AAP). This suggests that additional triggers are required to initiate the inflammatory process. Genetic susceptibility contributes to the development of AAP, and SPINK1 mutation is a documented risk factor.

Smoking cessation intervention prior to orthopedic surgery: A study protocol to determine patient outcomes and feasibility.

The aim of the study is to analyze the effect of smoking and smoking cessation on the incidence of complications among orthopedic and hand surgery patients, and to determine the feasibility of smoking cessation intervention, as well as factors predicting success in smoking cessation. Orthopedic and hand surgery patients will be invited to participate in the study, which will recruit 550 participants (at least 20% daily smokers). A participant will be defined as a daily smoker if he/she reports daily smoking and/or laboratory tests show active smoking.

The association between appendicitis severity and patient age with appendiceal neoplasm histology-a population-based study.

Purpose: Recent studies have reported alarming appendiceal tumor rates associated with complicated acute appendicitis, especially in patients presenting with a periappendicular abscess. However, the data on histology of appendiceal tumors among acute appendicitis patients is limited, especially in patient cohorts differentiating between uncomplicated and complicated acute appendicitis. We have previously reported the association of increased appendiceal tumor prevalence with complicated acute appendicitis in this population-based study.

Surgery for chronic pancreatitis in Finland is rare but seems to produce good long-term results.

Background: Abdominal pain in chronic pancreatitis (CP) may require invasive interventions. Surgical procedures are rare, and little is known about the long-term results.

Aim: To study the nationwide frequency of pancreatic surgery for CP in Finland, and postoperative symptoms and quality of life (QoL).

Long-term morbidity and mortality in patients diagnosed with an insulinoma.

Objective: Insulinomas are rare functional pancreatic neuroendocrine tumours. As previous data on the long-term prognosis of insulinoma patients are scarce, we studied the morbidity and mortality in the Finnish insulinoma cohort.

Design: Retrospective cohort study.

Perioperative acinar cell count method works well in the prediction of postoperative pancreatic fistula and other postoperative complications after pancreaticoduodenectomy.

Background: Earlier we have shown that high frequency of acinar cells in the pancreatic transsection line predicts postoperative pancreatic fistula after pancreaticoduodenectomy (PD). Acinar cell count method (ACM) is fast to perform during operation. In this study our aim was to validate the accuracy of ACM to compare it with other published risk prediction methods.

Regulation of p38 MAPK and glucocorticoid receptor activation by hydrocortisone in mono-and co-cultured pancreatic acinar and stellate cells.

Background/objectives: Acute pancreatitis develops as an inflammatory response to pancreatic tissue injury. Postoperative pancreatitis has recently been associated with increased occurrence of complications. Activation of the mitogen-activated protein kinase p38 (p38 MAPK) pathway occurs early in acute pancreatitis and its inhibition has been suggested to alleviate pancreatic inflammation.

Plasma suPAR may help to distinguish between chronic pancreatitis and pancreatic cancer.

Objectives: SuPAR (soluble urokinase-type plasminogen activator receptor) is a biomarker reflecting the inflammatory state of the human body. Earlier studies suggest that urinary suPAR/creatinine ratio levels are elevated in chronic pancreatitis (CP), and that plasma suPAR (P-suPAR) level is elevated in pancreatic cancer (PC). Our aim was to study the levels of P-suPAR in CP in a long-term prospective follow-up setting to explore the possibility of distinguishing between PC and CP.

Long-term health-related quality of life in persons diagnosed with an insulinoma in Finland 1980-2010.

Objective: Insulinomas are rare pancreatic neoplasms, which can usually be cured by surgery. As the diagnostic delay is often long and the prolonged hyperinsulinemia may have long-term effects on health and the quality of life, we studied the long-term health-related quality of life (HRQoL) in insulinoma patients.

Design, Patients And Measurements: The HRQoL of adults diagnosed with an insulinoma in Finland in 1980-2010 was studied with the 15D instrument, and the results were compared to those of an age- and gender-matched sample of the general population.

The European evidence-based guidelines on pancreatic cystic neoplasms (PCN) in clinical practice: The development of relative and absolute indications for surgery during prospective IPMN surveillance.

Introduction: The European evidence-based guidelines on PCN recommend surveillance for IPMN patients who are fit for surgery but who have no indication for immediate surgery. Our aim was to demonstrate the feasibility of the new guidelines in clinical practice.

Methods: This is a prospective cohort study of patients included in the IPMN register in Tampere University Hospital, Finland.

A population-based study of chronic pancreatitis in Finland: Effects on quality of life.

Background/objectives: In Finland the incidence of chronic pancreatitis (CP) is high compared to that in most European countries. Recent epidemiological data is lacking. Our aim was to investigate the current epidemiologic and behavioural data on CP patients in Finland.

Quality of Life and Patient Satisfaction at 7-Year Follow-up of Antibiotic Therapy vs Appendectomy for Uncomplicated Acute Appendicitis: A Secondary Analysis of a Randomized Clinical Trial.

Objective: To determine patient satisfaction and QOL after antibiotic therapy and appendectomy for treating uncomplicated acute appendicitis.

Perioperative hydrocortisone treatment reduces postoperative pancreatic fistula rate after open distal pancreatectomy. A randomized placebo-controlled trial.

Background: Postoperative pancreatic fistula (POPF) is the most common complication after distal pancreatectomy (DP). In a recent RCT on pancreaticoduodenectomy (PD), perioperative hydrocortisone (HC) treatment reduced Clavien-Dindo (C-D) III-V complications. The aim of this study was to investigate whether perioperative HC treatment reduces the overall complications and clinically significant POPF after distal pancreatectomy (DP).

Plasma level of soluble urokinase plasminogen activator receptor (suPAR) predicts long-term mortality after first acute alcohol-induced pancreatitis.

Background: Soluble urokinase plasminogen activator receptor (suPAR) is a biomarker associated with inflammatory and certain malignancies. Earlier we have shown that plasma suPAR (P-suPAR) predicts severity of acute alcohol-induced pancreatitis (AAP) on admission. Our aim was to investigate whether P-suPAR levels predict AAP recurrences or mortality during long-term follow-up after first AAP.

Characteristics and long-term survival of resected pancreatic cystic neoplasms in Finland. The first nationwide retrospective cohort analysis.

Background: Pancreatic cystic neoplasms (PCN) are being found increasingly in imaging studies. Even though the characteristics of PCN lesions have been studied extensively in single and multicentre settings, nationwide data is lacking. The aim of this study was to determine the nationwide epidemiologic characteristics and long-term survival of all resected PCNs.

Wnt/β-catenin signalling plays diverse functions during the process of fibrotic remodelling in the exocrine pancreas.

Background/objectives: Wnt/β-catenin signalling plays vital roles in tissue homeostasis. Dysregulation of the pathway has been implicated in the pathogenesis of cancer and fibroses in numerous tissues, including the pancreas. We studied the effect of microenvironmental changes pertaining to fibrotic tissue remodelling on the expression of selected Wnt/β-catenin pathway proteins in the human exocrine pancreas.

Characteristics and Outcomes of 79 Patients with an Insulinoma: A Nationwide Retrospective Study in Finland.

Objective: Insulinomas are rare pancreatic tumours. Population-based data on their incidence, clinical picture, diagnosis, and treatment are almost nonexistent. The aim of this study was to clarify these aspects in a nationwide cohort of insulinoma patients diagnosed during three decades.

Biodegradable biliary stents preferable to plastic stent therapy in post-cholecystectomy bile leak and avoid second endoscopy.

Background: The treatment of post-cholecystectomy bile leak is endoscopic retrograde cholangiography (ERC) with plastic stent (PS) insertion combined with external drainage. Self-expanding biodegradable biliary stents (BDBS) have only recently become available.

Aim: The aim was to compare success rate, adverse events and costs of BDBS with PS in the treatment of post-cholecystectomy cystic duct leak Materials and methods: Patients recruited prospectively for treatment with BDBS during the period 2014-2017 were compared to a control group treated with PS in a non-randomized setting.

Five-Year Follow-up of Antibiotic Therapy for Uncomplicated Acute Appendicitis in the APPAC Randomized Clinical Trial.
