Intestinal permeability in the pathogenesis of liver damage: From non-alcoholic fatty liver disease to liver transplantation.
Intestinal permeability in the pathogenesis of liver damage: From non-alcoholic fatty liver disease to liver transplantation. World J Gastroenterol. 2019 Sep 07;25(33):4814-4834 Authors: Nicoletti A, Ponziani FR, Biolato M, Valenza V, Marrone G, Sganga G, Gasbarrini A, Miele L, Grieco A Abstract The intimate connection and the strict mutual cooperation between the gut and the liver realizes a functional entity called gut-liver axis. The integrity of intestinal barrier is crucial for the maintenance of liver homeostasis. In this mutual relationship, the liver acts as a second firewall towards potentially harmful substances translocated from the gut, and is, in turn, is implicated in the regulation of the barrier. Increasing evidence has highlighted the relevance of increased intestinal permeability and consequent bacterial translocation in the development of liver damage. In particular, in patients with non-alcoholic fatty liver disease recent hypotheses are considering intestinal permeability impairment, diet and gut dysbiosis as the primary pathogenic trigger. In advanced liver disease, intestinal permeability is enhanced by portal hypertension. The clinical consequence is an increased bacterial translocation that further worsens liver damage. Furthermore, this pathogenic mechanism is implicated in most of liver cirrhosis complications, such as spontaneous bacterial peritonitis, hepatorenal syndrome, portal vein thrombosis, hepatic encephalopathy, and h...
CONCLUSION: Primary Signet ring cell carcinoma of the prostate is a rare and aggressive histological variant of adenocarcinomas of the prostate. Treatment is the same as classical adenocarcinoma with an emphasis on aggressive multimodal treatment. PMID: 31797810 [PubMed - in process]
Today's open access research on tryptophan and its role in age-related immune dysfunction is particularly interesting in the context of ongoing research into the changes that take place in gut microbiota with age. Other recent work has examined the way in which tryptophan production by gut microbes declines precipitously with age, as this is one of a number of compounds produced by bacteria, such as butyrate, indole, and proprionate, that are influential on long term health. It is a slow process, but researchers are uncovering the specific mechanisms linking age-related changes in gut microbe populations with declining hea...

The genetic predisposition for this autoimmune disease is largely attributed to MHC class II genes, especially the main polymorphism in the HLA shared epitope. Non-genetic factors account for the rest. The best known are autoantigens to citrullinated or carbmylated proteins, although there are many others. They are recognized by an ...
Conclusions: There is substantial interest in learning to perform DMEK among the surgical community. Barriers identified in this survey may be addressed to help surgeons increase DMEK adoption.
Conclusions: The results indicate no difference in graft survival between PK and EK for ICE syndrome. Graft survival in ICE syndrome is intermediate between that of FED and PBK.
Conclusions: The use of alternate topical corticosteroids may be considered in cases of steroid-induced ocular hypertension after PKP because they offer good antiinflammatory prophylaxis with reduced hypertensive response.
Conclusions: DM suturing can reattach DM, especially in moderate to severe, recurrent DMD with fewer postoperative complications and thereby reduce the need for corneal transplantation.
Conclusions: Tear lipids are more ordered than meibum lipids, which could have functional consequences. The human meibum peak height ratio of the CH3/CH2 bands is not a factor related to tear film stability with age or sex. The amount of CH3 moieties relative to CH2 moieties and saturation could contribute to a higher meibum lipid order associated with a younger age, meibomian gland dysfunction, and dry eye from hematopoietic stem cell transplantation. Therefore, the hydrocarbon order may be a marker of or contribute to an unstable tear film layer.
ConclusionIn a large series of advanced ovarian cancer, patients receiving late IDS (≥ 5 NAC cycles) seem to show a poorer prognosis than patients operated on earlier. The survival appears to be mainly determined by optimal resection and response to chemotherapy.
ConclusionThe lack of conclusive evidence on polyphenol effectiveness in the management of cardio-metabolic risk factors does not allow to recommend their use as supplements to reduce T2D and CVD risk. However, the daily consumption of naturally polyphenol-rich foods and beverages might be advised according to the current nutritional dietary recommendation.
