A large-scale multivariate soccer athlete health, performance, and position monitoring dataset.

Data analysis for athletic performance optimization and injury prevention is of tremendous interest to sports teams and the scientific community. However, sports data are often sparse and hard to obtain due to legal restrictions, unwillingness to share, and lack of personnel resources to be assigned to the tedious process of data curation. These constraints make it difficult to develop automated systems for analysis, which require large datasets for learning. We therefore present SoccerMon, the largest soccer athlete dataset available today containing both subjective and objective metrics, collected from two different elite women's soccer teams over two years. Our dataset contains 33,849 subjective reports and 10,075 objective reports, the latter including over six billion GPS position measurements. SoccerMon can not only play a valuable role in developing better analysis and prediction systems for soccer, but also inspire similar data collection activities in other domains which can benefit from subjective athlete reports, GPS position information, and/or time-series data in general.

Bone Metabolism in Inflammatory Bowel Diseases 2.

Inflammatory Bowel Disease encompasses Crohns Disease, which is capable of affecting the entire GI tract, although usually favors the ileocolonic and perianal areas, and Ulcerative Colitis, which is limited to the colon. The pathophysiology is not fully understood but is thought to be caused by a complex interplay among gut microbiota, dysregulation of the hosts immune system, genetic susceptibility and environmental factors. Osteopenia and osteoporosis are considered to be extraintestinal manifestations of inflammatory bowel disease. Osteoporosis is usually diagnosed by dual-energy X-ray absortiometry. Early interventions to treat active CD and preventative treatment strategies to reduce excessive bone loss might prevent long term consequences of bone loss, including fractures. The immune response in IBD includes increased production of variety of proinflammatory cytokines such as IL1β, TNFα, IL6 a IL1 from T cells and macrophages. These have both direct and indirect effects on bone turnover. Vitamin D is vital in mantenance of bone strenght, mineralisation and fracture prevention. Vitamin Ds physiological importance has also been implicated in a number of inflammatory diseases, mainly asthma, atherosclerosis and autoimmune disease.

Infliximab pharmacokinetics monitoring in inflammatory bowel disease.

Therapeutic drug monitoring is a strategy utilized to optimize biological therapy. It consists in the drug level measurement before the next dose is due, when the drug concentration reaches the trough level, and includes the detection of potential antidrug antibodies. The monitoring makes it possible to adjust the therapy accordingly - to intensify or change the biologics applied to secure safe and highly effective therapeutics. Therapeutic optimization is based on the nature of therapy failure, which can be caused by pharmacokinetic or pharmacodynamic factors. Pharmacokinetic monitoring can be currently classified as reactive, measuring the drug level and antidrug antibodies during therapy failure, or adverse reactions to the drug applied, and proactive, monitoring patients in clinical remission to retain remission and prevents development of a secondary failure.

Idiopathic inflammatory bowel disease and the first type of autoimmune form of pancreatitis: case report.

The autoimmune form of pancreatitis (AIP) is divided into the following two subtypes. The 1st subtype is characterized by the high presence of immunoglobulin G4 in the blood serum and tissue of some organs which are in the close connection to the so called IgG4 associated disorders. The typical diagnostic signs of AIP are the histomorphological changes. This type of AIP is more frequent than the 2nd type with which has however some common histomorphological signs and mainly the positive response to the administered steroids used in the initial treatment. Whilst the 1st type of AIP is typically connected to the disorders of various organs such are the biliary tract, salivary and lacrimal glands, retroperitoneal fibrosis, reins, prostate gland and the next ones, the 2nd type of AIP is significantly connected to the inflammatory bowel disease only. Inflammatory bowel diseases are rarely present in the 1st type of AIP on the contrary. In our case report we mention the first published observations performed in the Czech Republic when the 1st type of AIP is succeeded by the inflammatory bowel disease - Crohn´s disease.

Crohn's disease - genetic factors and progress of the disease.

BACKGROUND AND OBJECTIVES: Crohn's disease is a multifactorial inflammatory disease affecting mainly the gastrointestinal tract. The genetic factors that are involved in the disease include mainly three mutations of the gene NOD2/CARD15 (R702W, G908R, 3020insC). The aim of this study was to determine the relationship between the presence of these variants and disease phenotype. MATERIAL AND METHODS: 70 patients with Crohn's disease were examined for the presence of the above-mentioned mutations. The researchers used the medical records to retrospectively obtain clinical data and together with the information obtained prospectively according to the protocol they analysed the connection between gene mutations and disease phenotype. RESULTS: At least one mutation was found in 22 patients with Crohn's disease (32%), four patients were found to have two different mutations (composed heterozygotes - 6%) and six patients (9%) were homozygotes for the 3020insC gene. No significant differences were found between the groups with wild-type form and the mutated form of the NOD2 / CARD15 gene with respect to age at the time of diagnosis, form of the disease or localization according to the Montreal classification. CONCLUSION: Mutations of the NOD2 / CARD15 gene did not significantly affect the frequency of reoperations, homozygotes with 3020insC gene mutations, however, represented a high risk group. The phenotype was not related significantly to the presence of the examined mutations.

[Adiponectin in patients with metabolic syndrome and diseases of the liver, bile ducts and pancreas]. / Adiponektin u nemocných s metabolickým syndromem a chorobami jater, zlucových cest a pankreatu.

Epidemiological data show that the metabolic syndrome can be diagnosed in up to 30 % of the population. Regarding 5 components of the metabolic syndrome, three of them, in case of positivity (visceral obesity, arterial hypertension, hypertriglyceridemia, changes of HDL-cholesterol levels and type 2 diabetes mellitus), are pathogenic factors which are the most frequently related to cardiovascular diseases, but currently they are also the focus of interest for gastroenterologists. The relationship between non-alcoholic hepatic steatosis, including non-alcoholic steatohepatitis, has been described. Less is known so far about the relation to the pancreas disease, particularly with respect to the status referred to as non-alcoholic fatty pancreas disease. The hormone selectively produced by adipose tissue is adiponectin. This protein is studied as a possible biomarker in people with metabolic syndrome, including obesity. Besides that, there is a question studied whether adiponectin can also play a significant role in the pathogenesis of diseases associated with fat building up in parenchymatous organs. Finding a reliable biomarker for patients with metabolic syndrome or diseases of the liver, biliary system and pancreas in relation to metabolic syndrome, presents a big challenge. And adiponectin is one of the promising biomarkers.Key words: adiponectin - biliary disease - metabolic syndrome - pancreatic steatosis - steatohepatitis.

[A contribution to the differential diagnostics of sclerosing cholangitides]. / Príspevek k diferenciální diagnostice sklerozujících cholangitid.

Sclerosing cholangitides represent a group of chronic biliary obstructive diseases which include primary sclerosing cholangitis (PSC), IgG4 associated sclerosing cholangitis (IgG4-SC) and secondary sclerosing cholangitis (SSC). The manifestations of the diseases are similar, but their asymptomatic course is also frequent. IgG4-SC belongs to the group of IgG4 associated diseases and it is the most frequently related to type 1 autoimmune pancreatitis. Diagnosing of IgG4-SC is based on typical histopathological images, shape changes revealed by diagnostic imaging, serological tests, concurrent impairment of other organs and response to therapy, where IgG4-SC responds well to treatment with corticoids, whereas the only possibility for the remaining units is endoscopic intervention or liver transplantation. Secondary sclerosing cholangitis may develop as a result of many different insults affecting the biliary tree. Among them, the most frequently described include long-lasting biliary obstruction, surgical injury of the biliary tree, and ischemic cholangitis in liver allotransplants or recurrent pancreatitis. We use serological and imaging examination in PSC diagnostics, sometimes we have to resort to liver biopsy. PSC is to a significant degree accompanied by the presence of idiopathic bowel disease, typically ulcerative colitis. As a result, PSC may lead to cirrhosis of the liver and it is a precancerous condition of several malignancies. With regard to variable locations of the biliary tree injuries concerning the aforementioned units, also certain malignancies in subhepatic landscape need to be considered in the differential diagnosis: pancreatic cancer and cholangiogenous carcinoma.Key words: genetic factors - IBD - IgG4 cholangitis - liver transplantation - bile duct cancer - ursodeoxycholic acid - primary sclerosing cholangitis - secondary cholangitis - sclerosing cholangitis.

Elipse, the first procedureless gastric balloon for weight loss: a prospective, observational, open-label, multicenter study.

Background and study aims Conventional gastric balloons for weight loss require endoscopy for placement and removal. The Elipse device is swallowed, resides in the stomach for 4 months, and is then expelled. The objectives of this study were to assess the safety of Elipse and to measure its effects on weight loss, metabolic parameters, and quality of life. Methods Each participant swallowed one Elipse device, which was filled with 550 mL of filling fluid through a thin delivery catheter that was then removed. Weight was measured every 2 weeks, and metabolic parameters and quality of life were assessed at baseline and at trial exit. Results 34 patients, with a mean body mass index of 34.8 kg/m2, were enrolled. All 34 patients successfully swallowed the Elipse device. All adverse events were either self-limiting or resolved with medication. All balloons were safely excreted. At 4 months, the mean percent total body weight loss was 10 %. Mean waist circumference was reduced by 8.4 cm. Improvements were also seen in hemoglobin A1c, triglycerides, low density lipoprotein, and blood pressure. At trial exit, quality of life measures had improved across all domains. Conclusion These results demonstrate clinically significant weight loss with the Elipse, the first procedureless gastric balloon. The weight loss was similar to that seen in previous studies of endoscopically placed balloons. In addition, Elipse therapy led to improvements in waist circumference, several metabolic parameters, and overall quality of life.ClinicalTrials.gov identifier: NCT 02802007.

[Chronic pancreatitis diagnosed after the first attack of acute pancreatitis]. / Chronická pankreatitida diagnostikovaná po první atace akutní pankreatitidy.

INTRODUCTION: One of the diseases involving a potential risk of developing chronic pancreatitis is acute pancreatitis. MATERIAL: Of the overall number of 231 individuals followed with a diagnosis of chronic pancreatitis, 56 patients were initially treated for acute pancreatitis (24.2 %). Within an interval of 12- 24 months from the first attack of acute pancreatitis, their condition gradually progressed to reached the picture of chronic pancreatitis. The individuals included in the study abstained (from alcohol) following the first attack of acute pancreatitis and no relapse of acute pancreatitis was proven during the period of their monitoring. RESULTS: The etiology of acute pancreatitis identified alcohol as the predominant cause (55.3 %), biliary etiology was proven in 35.7 %. According to the revised Atlanta classification, severe pancreatitis was established in 69.6 % of the patients, the others met the criterion for intermediate form, those with the light form were not included. CONCLUSION: Significant risk factors present among the patients were smoking, obesity and 18 %, resp. 25.8 % had pancreatogenous diabetes mellitus identified. 88.1 % of the patients with acute pancreatitis were smokers. The majority of individuals with chronic pancreatitis following an attack of acute pancreatitis were of a productive age from 25 to 50 years. It is not only acute alcoholic pancreatitis which evolves into chronic pancreatitis, we have also identified this transition for pancreatitis of biliary etiology.

[The rational diagnostic of cholangiocarcinoma]. / Racionální diagnostika cholangiokarcinomu.

Cholangiocarcinoma (CC) is a rare malignant tumour arising from cholangiocytes, and its prognosis is usually unfavourable, mostly as a result of late diagnosis of the tumour. The current incidence of cholangiocarcinoma in the Czech Republic is 1.4/100,000 inhabitants per year; in less than 30 % of patients with CC, one of the known risk factors can be identified, most frequently, primary sclerosing cholangitis. Only patients with early diagnosed and surgically amenable cholangiocarcinoma are likely to have a longer survival time; in their case, survival for more than five years has been achieved in 20 % to 40 %. From the perspective of the need for early diagnosis of CC, a significant part is played by imaging and histopathologic evaluation; the early diagnostic significance of oncomarkers is limited. The rational early diagnosis of CC consists in effective use of differentiated advantages of different imaging modalities - MRI with DSA appears to be the optimal method, endosonography is a sensitive method for the identification of malignancy in the hepatic hilum or distal common bile duct, MRCP (magnetic resonance cholangiopancreatography) is used to display pathological changes in the biliary tree, ERCP (endoscopic retrograde cholangiopancreatography) allows material removal for histopathological examination. Other new approaches are also beneficial, such as IDUS - intraductal ultrasonography of biliary tract or SPY-GLASS, enabling examination of the bile ducts by direct view with the possibility of taking targeted biopsies. Sensitivity and specificity of histology and cytology can be increased by using the molecular cytogenetic FISH method, i.e. fluorescence in situ by hybridization, with a specificity of 97 %.

Short-term outcomes of the new intragastric balloon End-Ball® for treatment of obesity.

INTRODUCTION: Intragastric balloons (IGBs) have been successfully used to treat obesity for the last 18 years. These balloons are made of different materials and filled with either air or saline. It seems that balloons filled with saline result in more effective weight loss, but are associated with worse tolerance after implantation. In contrast, balloons filled with air are associated with excellent tolerance, but result in less effective weight loss. AIM: To report the early safety and effectiveness results of the End-Ball® balloon and to encourage discussions on how to best use this new-generation IGB for endoscopic weight loss management. MATERIAL AND METHODS: Twenty obese patients (mean age: 40.5 years; mean body mass index: 34.8 kg/m2) were included in a 6-month study. Balloons were inflated with 300 ml of saline containing 5 ml of methylene blue and 300 cm3 of air. RESULTS: No serious adverse events occurred during treatment. Patients experienced varying degrees of nausea, vomiting (mean: 3.7 times the first day), and abdominal pain after implantation. Six months (23-29 weeks) after End-Ball® balloon insertion, we observed a significant decrease in body weight (13.9 ±5.1 kg) and percent excess weight loss (37.9 ±12.9%). We also found a significant decrease in the levels of glycated hemoglobin (p < 0.001), C-peptide (p < 0.002), and triacylglycerols (p < 0.001) and an increase in the concentration of high-density lipoprotein cholesterol (p < 0.025). CONCLUSIONS: The End-Ball® IGB is a safe and effective treatment for morbid obesity, with positive effects on weight loss and saccharide metabolism.

Elipse™, a Procedureless Gastric Balloon for Weight Loss: a Proof-of-Concept Pilot Study.

BACKGROUND: Endoscopic gastric balloons have been used effectively as weight loss devices for decades, but the requirement for endoscopy and sedation poses several limitations. The goal of this pilot study was to evaluate the safety and performance of a prototype version of Elipse™, a procedureless gastric balloon. METHODS: Eight patients (mean BMI = 31.0 kg/m(2)) participated in this study. Each patient swallowed one Elipse™ balloon intended to remain in the stomach for 6 weeks, self-empty, and then pass. Each balloon was filled with 450 mL of filling fluid. Patients returned every 2 weeks for abdominal ultrasound. No specific diet or exercise plan was prescribed. RESULTS: All eight patients successfully swallowed the device. The most common adverse events were nausea and vomiting. There were no serious adverse events, and all balloons were excreted safely. Despite not being prescribed a diet or exercise plan, all eight patients lost weight. In 6/8 patients, the balloon remained full through 6 weeks, self-emptied, and passed. In one patient, the balloon appeared partially collapsed on ultrasound after 11 days and was endoscopically punctured. One asymptomatic patient elected to have the balloon endoscopically punctured after 19 days. Both balloons passed in the stool after 4 days. In both cases, endoscopic examination of the upper GI tract showed no abnormalities. CONCLUSIONS: This pilot study demonstrates the safety and performance of Elipse™, a procedureless gastric balloon for weight loss. Future studies will test a commercial design filled to 550 mL intended to last in the stomach for at least 12 weeks.

A RARE PARASITIC DISEASE OF THE LIVER - ALVEOLAR ECHINOCOCCOSIS.

Alveolar echinococcosis is a rare parasitic disease, especially of the liver, caused by the larval stage of the tapeworm Echinococcus multilocularis. At the end of the last century France, Germany, Austria and Switzerland were the regions where this disease most often manifested itself, these days this infection is diagnosed also in our territory. We describe the case of the disease of a twenty-five-year-old male with nonspecific signs and hepatomegaly, who was diagnosed on the basis of imaging and laboratory sampling. Due to inoperability the patient is now in infectologist follow-up on long-term treatment with Albendazole. He is clinically stable, included on the waiting list for liver transplantation.

[The role of metabolic syndrome in gastroenterology]. / Role metabolického syndromu v gastroenterologii.

GOAL: Metabolic syndrome and its components play an important part in the development of not only cardiovascular conditions, but also digestive and pancreaticobiliary system diseases. The aim of our study is to present a comprehensive overview of the diseases where metabolic syndrome is an inducing risk factor, or where it affects the course of the disease. RESULTS: Metabolic syndrome is a significant risk factor of induction of gastroesophageal reflux and its complication, which is Barretts esophagus. Metabolic syndrome was described as the disease closely linked to idiopathic intestinal inflammations, diseases of the biliary tree and pancreas. Acute pancreatitis, both its development in obese individuals and the burden of its course, are in close correlation with metabolic syndrome, similarly as the course of chronic, mainly alcoholic pancreatitis. Study of non-alcoholic steatopancreatitis presents a challenge, most importantly with regard to the function of pancreatic B cells in obese individuals. Non-alcoholic hepatic steatosis and its forms may as much as lead to the stage of cirrhosis of the liver and they pose a risk of hepatocellular carcinoma. Metabolic syndrome was also described in a population study as a risk factor for carcinoma of the colon. SUMMARY: Metabolic syndrome and its components present an important risk factor in relation to inducing some benign as well as malignant gastrointestinal and pancreaticobiliary diseases. A systemic approach to influencing the metabolic syndrome and its components is therefore one of the important approaches to influencing the development and course of not only cardiovascular conditions.

[Crohn's disease - etiopathogenetic factors]. / Crohnova nemoc - genetické faktory z pohledu etiopatogeneze.

Crohn's disease is often purely inflammatory, but most patients develop complicated disease with strictures or fistulae. Specific etiopathogenesis of this severe disease is not definitely clear despite research efforts and learning of many pathogenetic mechanisms. Many studies have suggested that NOD2 mutations are associated with increased risk of complicated disease. Presence of NOD2 mutation itself is just one of factors contributing to development of this disease. Genetically predisposed individuals in combination with influence of environmental factors result in a disturbed innate (i.e., disturbed intestinal barrier, Paneth cell dysfunction) and adaptive (i.e., imbalance of effector and regulatory T cells and cytokines, migration and retention of leukocytes) immune response towards a diminished diversity of commensal microbiota. Data of meta-analysis made so far provide ambiguous evidence to support top-down therapy based solely on single NOD2 mutations, but suggest that targeted early-intensive therapy for high-risk patients with two NOD2 mutations might be beneficial, but more prospective trials could answer these questions.

[Pain in chronic pancreatitis and pancreatic cancer - treatment options]. / Bolest u chronické pankreatitidy a karcinomu pankreatu - moznosti lécby.

Treatment of pain is one of the main pillars of treatment of pancreatic diseases. Abdominal pain is a common and often debilitating symptom in patients with chronic pancreatitis and pancreatic cancer. Treatment involves abstinence from tobacco, alcohol and analgetics and adjunctive agents. Surgical and endoscopic treatment requires careful patient selection based on a detailed analysis of ductal anatomy. The limited possibilities of this therapy are patients without dilatation of the main pancreatic duct. Results of randomized trials suggest that the effect of surgical treatment is sustained over time and more efficient than the endoscopic treatment. Less frequently used options include EUS - assisted celiac plexus blockade, thoracoscopic splanchniectomia or total pancreatectomy with islet cell autotransplantation. These methods are rarely used when all other options have failed and only in carefully selected patients.

[Risk factors and progression predictors of Barrett´s oesophagus to adenocarcinoma]. / Rizikové faktory a prediktory progrese Barrettova jícnu do adenokarcinomu.

Gastroesophageal reflux disease is a quite common disorder, and the condition affects some 40 per cent of population in the course of their lifetime. Fortunately, about half of the patients examined due to clear symptoms do not manifest macroscopic damage of the oesophageal mucosa, and serious endoscopic findings (Barrett's oesophagus) are observed in only a small percentage of patients (10%). Barrett's oesophagus is a serious complication - precancerous condition with a 30-fold higher risk of development of oesophageal adenocarcinoma when compared with patients without this condition. The article presents risk factors and predictors of progression of the Barrett's oesophagus into the stage of adenocarcinoma. The main risk factors associated with oesophageal adenocarcinoma are male sex, white race, gastroesophageal reflux.
