Predictive Potential of Biomarkers of Intestinal Barrier Function for Therapeutic Management with Teduglutide in Patients with Short Bowel Syndrome.

Introduction: The human intestinal tract reacts to extensive resection with spontaneous intestinal adaptation. We analyzed whether gene expression analyses or intestinal permeability (IP) testing could provide biomarkers to describe regulation mechanisms in the intestinal barrier in short bowel syndrome (SBS) patients during adaptive response or treatment with the glucagon-like peptide-2 analog teduglutide.

Methods: Relevant regions of the GLP-2 receptor gene were sequenced.

The Role of Alternative Lymph Node Classification Systems in Gastroenteropancreatic Neuroendocrine Neoplasms (GEP-NEN): Superiority of a LODDS Scheme Over N Category in Pancreatic NEN (pNEN).

Lymph node (LN) involvement in gastroenteropancreatic neuroendocrine neoplasms (GEP-NEN) has been reported to have prognostic and therapeutic implications. Numerous novel LN classifications exist; however, no comparison of their prognostic performance for GEP-NEN has been done yet. Using a nationwide cohort from the German Neuroendocrine Tumor (NET) Registry, the prognostic and discriminatory power of different LN ratio (LNR) and log odds of metastatic LN (LODDS) classifications were investigated using multivariate Cox regression and C-statistics in 671 patients with resected GEP-NEN.

Long-term results of teduglutide treatment for chronic intestinal failure - Insights from a national, multi-centric patient home-care service program.

Background & Aims: Teduglutide is a Glucagon-like peptide-2 (GLP-2) agonist indicated for the treatment of patients with parenteral support (PS) dependent short bowel syndrome (SBS) with chronic intestinal failure (cIF). Its application is accompanied by a structured nation-wide home-care service program in Germany. We investigated care characteristics and outcome parameters in a clinical real-world observational setting.

The European Neuroendocrine Tumour Society registry, a tool to assess the prognosis of neuroendocrine neoplasms.

Background: Neuroendocrine neoplasms (NENs) are rare tumours with variable clinical behaviour. Their natural history is ideally best approached in large, multicentre and multinational registries with long-term patients' follow-up. The European Neuroendocrine Tumour Society registry aims to obtain information regarding NEN outcomes and prognostic factors in a European frame.

Pulsed-field ablation combined with ultrahigh-density mapping in patients undergoing catheter ablation for atrial fibrillation: Practical and electrophysiological considerations.

Background: Pulsed-field ablation (PFA) yields a novel ablation technology for atrial fibrillation (AF). PFA lesions promise to be highly durable, however clinical data on lesion characteristics are still limited.

Objective: This study sought to investigate PFA lesion creation with ultrahigh-density (UHDx) mapping.

De Novo Development of Distal Jejunal and Duodenal Adenomas After 41 Months of Teduglutide Treatment in a Patient With Short-Bowel Syndrome: A Case Report.

The glucagon-like peptide-2 (GLP-2) analogue teduglutide is a medical treatment option for patients with short-bowel syndrome-associated chronic intestinal failure. Because studies in mice have shown that GLP-2 analogues may promote the growth of colonic neoplasms, surveillance colonoscopies before and during teduglutide therapy were recommended. The occurrence of small-intestinal neoplasms has not been reported so far, except for a recent report about de novo development of hamartomatous duodenal polyps.

Oral intake and plasma citrulline predict quality of life in patients with intestinal failure.

Objective: Chronic intestinal failure (cIF) is a rare medical condition usually treated by long-term parenteral nutrition (PN). Owing to disease-associated symptoms and treatment-specific complications, patients with cIF commonly present with reduced quality of life (QoL) compared with healthy controls. The aim of this study was to identify factors associated with QoL in patients with cIF.

Long-term outcome of surgical resection in patients with gastroenteropancreatic neuroendocrine neoplasia: results from a German nation-wide multi-centric registry.

Background: Neuroendocrine neoplasia (NEN) are rare and heterogenous tumours. Few data exist on the impact of surgical therapy.

Materials And Methods: This is a retrospective analysis of prospectively collected data of gastroenteropancreatic NEN in the German NET-Registry (1999-2012).

Assessing Non-Invasive Liver Function in Patients with Intestinal Failure Receiving Total Parenteral Nutrition-Results from the Prospective PNLiver Trial.

Liver abnormalities in intestinal failure (IF) patients receiving parenteral nutrition (PN) can progress undetected by standard laboratory tests to intestinal failure associated liver disease (IFALD). The aim of this longitudinal study is to evaluate the ability of non-invasive liver function tests to assess liver function following the initiation of PN. Twenty adult patients with IF were prospectively included at PN initiation and received scheduled follow-up assessments after 6, 12, and 24 months between 2014 and 2019.

[Intestinal Rehabilitation in Short Bowel Syndrome and Chronic Intestinal Failure].

Patients with severely orally decompensated malsaborption due to surgical rescetion suffer from short bowel syndrome (SBS). The resultant decrease in intestinal surface area after rescetion of parts of the intestines leads to chronic functional intestinal insufficiency or even complete failure (cIF) which requires parenteral fluid and nutrient restoration for establishment of metabolc stability. Since the introduction of glucagon-like peptide (GLP)-2 analogues such as teduglutide functional rehabilitation of the remaining gastrointestinal tract has become a causal treatment option.

Gastric neuroendocrine neoplasias: manifestations and comparative outcomes.

Although gastric neuroendocrine neoplasias (gNEN) are an orphan disease, their incidence is rising. The heterogeneous clinical course powers the ongoing discussion of the most appropriate classification system and management. Prognostic relevance of proposed classifications was retrospectively analysed in 142 patients from a single tertiary referral centre.

Malnutrition predicts long-term survival in hospitalized patients with gastroenterological and hepatological diseases.

Background & Aims: Malnutrition is a common problem in hospitalized patients, influencing treatment outcomes, length of hospital stay, quality of life and overall survival. However, the association of nutritional status parameters with long-term mortality has not yet been studied systematically in gastroenterological-hepatological patients. The present study aimed to assess the association between nutritional status parameters as characterized by Nutritional Risk Screening (NRS), anthropometry, serum transferrin, bioelectrical impedance analysis (BIA) and long-term overall survival in hospitalized gastroenterological-hepatological patients.

Advanced liver function assessment in patients with intestinal failure on long-term parenteral nutrition.

Background & Aims: Intestinal failure associated liver disease (IFALD) is one of the leading complications and causes of deaths in adult patients receiving home parenteral nutrition for chronic intestinal failure (CIF). Early diagnosis of IFALD is key to alleviate the progression of hepatic dysfunction. The aim of this study was to evaluate the capability of noninvasive liver function tests.

Determinants of Quality of Life in Patients With Intestinal Failure Receiving Long-Term Parenteral Nutrition Using the SF-36 Questionnaire: A German Single-Center Prospective Observational Study.

Background: Parenteral nutrition (PN) is a life-sustaining therapy for patients with chronic intestinal failure (IF) but inevitably has an impact on patients' quality of life (QoL). The purpose of this study was to examine multiple aspects of QoL by utilizing the standardized Short Form 36 (SF-36) health survey.

Methods: Between 2014 and 2017, a total of 90 adult patients with IF who were receiving PN were prospectively enrolled in an observational study.

Experience with teduglutide treatment for short bowel syndrome in clinical practice.

Background & Aims: Teduglutide, a glucagon-like peptide 2 (GLP-2) analog, is an approved medication specific for short bowel syndrome patients with chronic intestinal failure (SBS-IF). Due to its intestinotrophic properties, it improves intestinal absorption of fluids and nutrients, which was shown to reduce the need for parenteral support in clinical trials. The present report aims to describe the experience of teduglutide's effects in routine medical care with focus on clinical and nutritional effects.

Malnutrition Predicts Clinical Outcome in Patients with Neuroendocrine Neoplasia.

Malnutrition is a common problem in oncological diseases, influencing treatment outcomes, treatment complications, quality of life and survival. The potential role of malnutrition has not yet been studied systematically in neuroendocrine neoplasms (NEN), which, due to their growing prevalence and additional therapeutic options, provide an increasing clinical challenge to diagnosis and management. The aim of this cross-sectional observational study, which included a long-term follow-up, was therefore to define the prevalence of malnutrition in 203 patients with NEN using various methodological approaches, and to analyse the short- and long-term outcome of malnourished patients.

Management of follow-up of neuroendocrine neoplasias.

Neuroendocrine neoplasias (NEN) comprise heterogeneous epithelial neoplasms with a large variety of clinical presentations, treatment options and outcomes. Since potentially all NEN bear malignant potential it is important for long-term clinical management and improvement of outcome to decide on successful and oncologically and economically meaningful follow-up strategies. Evidence-based outcome data validating specific follow-up strategies are, however, not available to date and thus outcome data, known prognostic factors and clinical experience guide the decisions on follow-up regimens.

[Endoscopic therapy for gastroduodenal neuroendocrine neoplasms].

Neuroendocrine neoplasms (NEN) represent a group of potentially malignant tumors, which can be located in every section of the gastrointestinal tract, the pancreas and the bronchopulmonary system. Gastroduodenal NENs have a relatively good prognosis in comparison to other subentities, e.g.

Pharmacological strategies to enhance adaptation in intestinal failure.

Purpose Of Review: Intestinal failure because of more or less extensive resection of parts of the small and large intestine (short bowel syndrome) results from the reduction of absorptive surface of the remaining intestine and frequently results in dependence on parenteral nutrition. Parenteral nutrition, although lifesaving, is associated with short and long-term complications as well as with reduced quality of life and overall survival.

Recent Findings: Pharmacological enhancement of the physiological intestinal adaptive response by subcutaneous application of the glucagon-like peptide 2 analogue teduglutide results in an improved, hyperadaptive response.

[Neuroendocrine tumours of the GI tract--data from the German NET Registry].

Background: Neuroendocrine tumours (NET) are rare and heterogeneous neoplasia. To obtain valid data on epidemiology, diagnostics, therapy, prognosis and risk factors is the aim of the German NET registry.

Patients And Methods: Data from 2009 histologically proven NET were collected from 35 NET centres between 1999 and 2010.
