Clinical, Journal: Analysis of Genetic Association of Intestinal Permeability in Healthy First-degree Relatives of Patients with Crohn's Disease. (Pubmed Central) - May 31, 2020 Our objective was to determine the genetic determinants of altered gut permeability as measured by the lactulose mannitol fractional excretion ratio (LacMan ratio) in 1075 healthy first-degree relatives of patients with Crohn's disease (CD)...It remains possible that smaller genetic effect sizes on LacMan ratio are not detectable in this sized cohort. Larger studies are warranted to identify the potential genetic contribution to intestinal permeability.

Clinical, Journal: A Clonal Shiga Toxin-Producing Escherichia coli O121:H19 Population Exhibits Diverse Carbon Utilization Patterns. (Pubmed Central) - May 27, 2020 Although clinical ST-655 strains displayed higher metabolic activity than environmental ST-655 strains for several carbon substrates, including l-alaninamide, 5-keto-d-gluconic acid, 3-O-β-d-galactopyranosyl-d-arabinose, α-ketoglutaric acid, and lactulose, a few environmental strains with the enhanced metabolic potential for the above substrates were detected...Considering the ecological niches that STEC colonizes, increased metabolic potential for plant-derived carbohydrates, mucus-derived substrates, or secondary metabolites produced by the indigenous microorganisms might have been selected. Such traits would confer STEC competitive advantages and facilitate survival and adaptation of STEC population to a given niche, including infected humans.

[VIRTUAL] Effect of Sevelamer and a Synbiotic on Insulin Sensitivity in Obese Individuals () - May 18, 2020 - Abstract #ADA2020ADA_3441; Insulin sensitivity (euglycemic clamp), cholesterol, endotoxemia (LPS, LBP, CD14), and intestinal permeability (lactulose/mannitol ratio, zonulin) were assessed before and after intervention...Lean subjects saw no change in insulin sensitivity with either treatment. Neither treatment significantly altered plasma LPS or intestinal permeability in lean or obese subjects.In conclusion, sevelamer improves insulin sensitivity and LDL in obese subjects, and this effect is mostly independent of parameters of endotoxemia and intestinal permeability.

Journal: Lactulose: a model system to investigate solid state amorphization induced by milling. (Pubmed Central) - May 15, 2020 These constants have been determined by molecular dynamics simulations. The paper also shows how isothermal dissolution calorimetry can be used effectively for the determination of amorphization kinetics during grinding when the usual characterization techniques (DSC and powder X-ray diffraction) fail.

Journal: Kinetic study on the digestibility of lactose and lactulose using small intestinal glycosidases. (Pubmed Central) - May 15, 2020 Considering these conditions, lactulose showed high resistance to intestinal digestion by RSIE, resulting in low hydrolysis degrees (20.4%) after 5 h reaction. These results underline the suitability of these intestinal extracts under the studied conditions, as a reliable tool to evaluate carbohydrate digestion and support the evidences towards the higher resistance of galactosyl-fructose linkages during its intestinal degradation.

Clinical, Journal: Allergic reactions to cow's milk proteins in medications in childhood. (Pubmed Central) - May 13, 2020 Thus, limited lysosomal damage might induce autophagy, perhaps as a compensatory mechanism, a process that is beneficial to counteract neurodegeneration. We suggest caution in administration of pharmaceuticals containing milk allergens in children allergic to milk.

WHY DID IT HAPPEN? A QUALITATIVE STUDY OF PATIENTS WITH A READMISSION FOR HEPATIC ENCEPHALOPATHY () - May 4, 2020 - Abstract #DDW2020DDW_7063; While some readmissions were not preventable due to infections, the key findings demonstrate a role for continued education. Topics include early signs and symptoms of HE and strategies to manage dosing of lactulose to ensure its efficacy while minimizing its side effects’ disruption to our patients’ lives.

THE EFFECT OF PSYCHOLOGICAL STRESS INDUCED BY SKYDIVING ON INTESTINAL BARRIER FUNCTION () - May 4, 2020 - Abstract #DDW2020DDW_6731; Even though there was an activation of the HPA axis by skydiving, this activation was confined to the skydive itself and did not seem strong enough to affect the intestinal barrier. Future experimental models aiming to investigate the effect of stress on human intestinal barrier function should consider a sufficient exposure of time to the stressor.

CHALLENGING THE INTESTINAL BARRIER FUNCTION IN HUMANS – DEHYDRATION BY SAUNA AS A NEW IN VIVO MODEL () - May 4, 2020 - Abstract #DDW2020DDW_6730; Sauna dehydration increased small intestinal permeability in healthy volunteers, presumably without damaging the enterocytes, suggesting sauna dehydration as a new physiological challenge model for the intestinal barrier function. This model could be of use in clinical trials that aim to study the effect of medical or nutritional interventions (including pre- and probiotics) intended to strengthen the gut barrier function.

DIARRHEA IN THE LUNG TRANSPLANT RECIPIENT: A RETROSPECTIVE REVIEW AT A HIGH VOLUME TRANSPLANT INSTITUTION () - May 4, 2020 - Abstract #DDW2020DDW_5659; Other notable medications include atovaquone (5.6%), magnesium (5.6%), lactulose (4.5%), nintedanib (3.4%) and metformin (2.2%)...This could be due to vigilance and aggressive testing when diarrhea appears. Recognition of the multiple potential causes of diarrhea in LTx recipients will facilitate early diagnosis and treatment, leading to greater quality of life and potentially survival

IMPACT OF RACE AND ETHNICITY ON OUTCOMES IN A MULTI-CENTER NORTH AMERICAN COHORT OF INPATIENTS WITH CIRRHOSIS () - May 4, 2020 - Abstract #DDW2020DDW_4624; Cirrhotic patients who were not white and those with Hispanic ethnicity demonstrated differences in cirrhosis severity at presentation, reasons for admission and inpatient course related to ICU, LOS and transplant in a large North American cohort. However, liver and hospitalization-related factors, rather than race and ethnicity, were largely associated with these outcomes on multi-variable analysis.
