Limited validity of Mayo endoscopic subscore in ulcerative colitis with concomitant primary sclerosing cholangitis.

Background: Ulcerative colitis (UC) with concomitant primary sclerosing cholangitis (PSC) represents a distinct disease entity (PSC-UC). Mayo endoscopic subscore (MES) is a standard tool for assessing disease activity in UC but its relevance in PSC-UC remains unclear.

Aim: To assess the accuracy of MES in UC and PSC-UC patients, we performed histological scoring using Nancy histological index (NHI).

The Czech Home Parenteral Nutrition Registry REDNUP: Comprehensive Analysis of Adult Patients' Data.

Introduction: Home parenteral nutrition (HPN) is the primary treatment modality for patients with chronic intestinal failure, one of the least common organ failures. This article provides a retrospective analysis of the data collected on HPN patients in the Czech Republic over the past 30 years.

Methods: National registry data were collected using a standardised online form based on the OASIS registry (Oley - A.

The ω-3 Polyunsaturated Fatty Acids and Oxidative Stress in Long-Term Parenteral Nutrition Dependent Adult Patients: Functional Lipidomics Approach.

Omega-3 polyunsaturated fatty acids (ω-3PUFAs) are introduced into parenteral nutrition (PN) as hepatoprotective but may be susceptible to the lipid peroxidation while olive oil (OO) is declared more peroxidation resistant. We aimed to estimate how the lipid composition of PN mixture affects plasma and erythrocyte lipidome and the propensity of oxidative stress. A cross-sectional comparative study was performed in a cohort of adult patients who were long-term parenterally administered ω-3 PUFAs without (FO/-, = 9) or with (FO/OO, = 13) olive oil and healthy age- and sex-matched controls, ( = 30).

Familial Adenomatous Polyposis and Desmoid Tumor Treated with Multivisceral Transplantation and Kidney Autotransplantation: Case Report and Literature Review.

Introduction: Desmoid tumours (DT) are commonly associated with Gardener's syndrome. Their surgical resection may be complicated by their close proximity to major vessels, multiple organ involvement, and frequent local recurrence. Multivisceral transplantation (MVTx) is an alternative treatment for patients with intestinal and liver failure.

Retrospective Analysis of Bone Metabolism in Patients on Waiting List for Simultaneous Pancreas-Kidney Transplantation.

Posttransplant osteoporosis, which evolves from preexisting bone pathologies, represents a serious complication with deteriorating consequences. The aim of our study was to evaluate epidemiological data on bone mineral density (BMD) in subjects with type 1 diabetes (T1DM) in advanced stages of diabetic nephropathy indicated for simultaneous pancreas-kidney transplantation (SPK). We retrospectively compiled biochemical and densitometrical data from 177 patients with T1DM at CKD (chronic kidney disease) stages G4-G5 (115 men, 62 women, median age 40 yr, diabetes duration 23 yr) enrolled on waiting list for SPK for the first time between the years 2011 and 2016.

Microbiome and Metabolome Profiles Associated With Different Types of Short Bowel Syndrome: Implications for Treatment.

Background: The gut microbiome and metabolome may significantly influence clinical outcomes in patients with short bowel syndrome (SBS). The study aimed to describe specific metagenomic/metabolomics profiles of different SBS types and to identify possible therapeutic targets.

Methods: Fecal microbiome (FM), volatile organic compounds (VOCs), and bile acid (BA) spectrum were analyzed in parenteral nutrition (PN)-dependent SBS I, SBS II, and PN-independent (non-PN) SBS patients.

[Intestinal transplantation in Czech Republic].

Unlabelled: Intestinal transplantation represents a suitable treatment for patients with intestinal failure who then develop life-threatening complications of total parenteral nutrition and for some patients with complex abdominal disorders not suitable for conventional treatment.

Methods: prior to launch of the clinical program, preparation started in 2006 initially with extensive experimentation carried out on pigs. The clinical phase involved a specialized, multidisciplinary team who examined 23 patients being considered for transplantation.

Parenteral Nutrition-Associated Liver Disease: The Role of the Gut Microbiota.

Parenteral nutrition (PN) provides life-saving nutritional support in situations where caloric supply via the enteral route cannot cover the necessary needs of the organism. However, it does have serious adverse effects, including parenteral nutrition-associated liver disease (PNALD). The development of liver injury associated with PN is multifactorial, including non-specific intestine inflammation, compromised intestinal permeability, and barrier function associated with increased bacterial translocation, primary and secondary cholangitis, cholelithiasis, short bowel syndrome, disturbance of hepatobiliary circulation, lack of enteral nutrition, shortage of some nutrients (proteins, essential fatty acids, choline, glycine, taurine, carnitine, etc.

Trace Element Status (Zinc, Copper, Selenium, Iron, Manganese) in Patients with Long-Term Home Parenteral Nutrition.

Background: The objective of the present study was to determine concentrations of zinc (Zn), copper (Cu), iron (Fe), selenium (Se) in blood plasma and manganese (Mn) in the whole blood in patients with long-term home parenteral nutrition (HPN) in comparison to the control group.

Patients And Methods: We examined 68 patients (16 men and 52 women) aged from 28 to 68 years on a long-term HPN lasting from 4 to 96 months. The short bowel syndrome was an indication for HPN.

Intramyocellular lipid content in subjects with impaired fasting glucose after telmisartan treatment, a randomised cross-over trial.

Ectopic lipid accumulation in skeletal muscle is associated with insulin resistance. Telmisartan improves metabolic parameters in type 2 diabetic patients. The aim of our study was to evaluate the in vivo effect of telmisartan on intramyocellular lipid content (IMCL) in subjects with impaired fasting glucose (IFG) by magnetic resonance spectroscopy (MRS).

Epithelial markers of colorectal carcinogenesis in ulcerative colitis and primary sclerosing cholangitis.

Aim: To evaluate the expression of epithelial markers of colorectal carcinogenesis in patients with long-term ulcerative colitis (UC) and primary sclerosing cholangitis (PSC) before and after transplantation.

Methods: Eight patients with UC and PSC prior to liver transplantation (PSC-UC), 22 patients with UC after liver transplantation for PSC (OLT), 9 patients with active ulcerative colitis without PSC (UCA), 7 patients with UC in remission (UCR) and 10 controls (N) underwent colonoscopy with multiple biopsies. Specimens were analysed histologically and semi-quantitatively immunohistochemically for p53, Bcl-2 and cyclooxygenase-2 (COX-2) markers.

Comparison of various strategies for colorectal cancer screening tests.

Introduction: Colorectal cancer (CRC) is one of the most serious health problems worldwide and thus it is important to assess health and economic impacts of preventative CRC screening strategies.

Methods: For this reason, a theoretical model based on Markov chains is proposed to compare these strategies: fecal occult blood test, capsule endoscopy, once-life and twice-life colonoscopy, and no screening. The model predicts the health state of a population of individuals aged from 50 to 75 years.

Effect of telmisartan on selected adipokines, insulin sensitivity, and substrate utilization during insulin-stimulated conditions in patients with metabolic syndrome and impaired fasting glucose.

Objective: Telmisartan improves glucose and lipid metabolism in rodents. This study evaluated the effect of telmisartan on insulin sensitivity, substrate utilization, selected plasma adipokines and their expressions in subcutaneous adipose tissue (SAT) in metabolic syndrome.

Design And Methods: Twelve patients with impaired fasting glucose completed the double-blind, randomized, crossover trial.

Inflexibility of energy substrate oxidation in type 1 diabetic patients.

Obese, insulin-resistant patients have been shown to have metabolic inflexibility. The goal of this study was to examine the effect of insulin administration on energy metabolism in lean, type 1 diabetic (DM1) patients. Eleven DM1 patients without vascular complications and 11 healthy controls (C) were examined.

Activation of alpha2-adrenergic receptors blunts epinephrine-induced lipolysis in subcutaneous adipose tissue during a hyperinsulinemic euglycemic clamp in men.

The aim of this study was to investigate whether hyperinsulinemia modifies adrenergic control of lipolysis, with particular attention paid to the involvement of antilipolytic alpha2-adrenergic receptors (AR). Eight healthy male subjects (age: 23.9 +/- 0.
