The treatment of inflammatory bowel disease has evolved with the development of anti-TNF agents. In spite of long-term effectiveness, many patients do not respond or no longer responds to these drugs. Therefore, the development of new drugs that act on different inflammatory pathways has become necessary. Vedolizumab, a gut-specific biological agent, inhibits interaction α4β7 integrin with mucosal addressin cell adhesion molecule-1 without inhibiting systemic immune responses. Long-term vedolizumab therapy in patients with Crohn's disease and ulcerative colitis was safe and effective...

Inflammatory bowel disease (IBD) is a chronic, idiopathic inflammatory disease of gastrointestinal tract with waxing and waning clinical course, which may lead to irreversible bowel damage and a loss of bowel function. Cumulative intestinal damage results in complications such as stricture or fistulae, and eventually a large number of IBD patients undergo surgery. Notably, even during remission period (no clinical symptoms), subclinical inflammation often persists and the disease continues to progress. Therefore, the therapeutic target of IBD has been evolving from symptomatic control to mucosal healing to prevent structural intestinal damage...

Soo Young Na, Won Moon
It is important to have effective therapeutic strategies and goals in clinical practice and research of inflammatory bowel disease. Conventional end points for clinical trials in Crohn's disease and ulcerative colitis have been based on composite indices, such as the Crohn's Disease Activity Index and the Mayo Clinic Score. Although these indices have been shown to reduce the intestinal injury to some extent, satisfactory results have not been obtained in improving the quality of life of patients. Recently, alternative measures of outcome and definitions of response are being developed beyond symptoms...

The delay between symptom onset and diagnosis in axial spondyloarthritis (axSpA) remains unacceptably long; recently estimated to still be more than 6 years.1 Accumulating data demonstrates that early treatment with TNF-inhibitors reduces both disease activity and radiographic progression in ankylosing spondylitis, the prototypic form of axSpA.2 3 To encourage timely and correct diagnosis and enable early treatment, strategies to better identify patients with axSpA have been studied in several populations.4 This article is protected by copyright...

Does transjugular intrahepatic portosystemic shunt stent (TIPS) improve survival in a subgroup of patients? Yes. TIPS nearly halves portal pressure and increases the effective blood volume. In cases of acute variceal hemorrhage and with a high risk of treatment failure, defined as either hepatic venous pressure gradient higher than 20 mm Hg, Child B with active bleeding at the endoscopy, or Child C with less than 14 points, early or preemptive placement of TIPS (within 72 hours) improves survival. Also, in suitable patients with intractable or refractory ascites, TIPS improves survival if placed early in the course of treatment...

The receptor interacting serine/threonine kinase1 and 3 (RIPK1, RIPK3) are regulators of cell death and survival. RIPK1 kinase activity is required for necroptosis and apoptosis, while its scaffolding function is necessary for survival. Although both proteins can mediate apoptosis, RIPK1 and RIPK3 are most well-known for their role in the execution of necroptosis via the mixed lineage domain like pseudokinase. Necroptosis is a caspase-independent regulated cell death program which was first described in cultured cells with unknown physiologic relevance in the liver...

The broadening field of microbiome research has led to a substantial reappraisal of the gut-liver axis and its role in chronic liver disease. The liver is a central immunologic organ that is continuously exposed to food and microbial-derived antigens from the gastrointestinal tract. Mucosal-associated invariant T (MAIT) cells are enriched in the human liver and can be activated by inflammatory cytokines and microbial antigens. In chronic inflammatory liver disease, MAIT cells are depleted suggesting an impaired MAIT cell-dependent protection against bacterial infections...

Cypermethrin (CYM), a type II pyrethroid, is widely used as an insecticide for agriculture and household. Cumulative evidence indicates that acute and chronic exposure to CYM might cause a number of health problems, such as cancer and neuronal system diseases. However, the molecular mechanism underlying this pathology is not known. The main objective of our study was to define the effects of CYM on macrophages and the implication of such effects in cancer metastasis and the potential mechanism involved. The effects of CYM on the macrophages were evaluated by detecting the expression of M1 and M2 macrophage polarization markers through ELISA, quantitative RT-PCR and Western blot assay...

Objective: To develop an optical spectral transmission (OST) model to measure joint inflammation, and thus disease activity, as well as to evaluate (patho-)physiological findings that could lead to misclassification of inflammation. Methods: Forty-six RA patients were included in this cross-sectional study, where US scores, duplicate OST measurements and 28-joint DAS (DAS28) were acquired. With US as a reference standard, the diagnostic performance of OST in detecting inflammation at the joint level was evaluated using receiver operating characteristic (ROC) curve analyses...

Objectives: To compare the trabecular bone score (TBS) between patients with axial spondyloarthritis (axSpA) and matched normal controls and identify risk factors associated with a low TBS. Methods: TBS and BMD were assessed in the two groups (axSpA and control) using DXA. Osteoporosis risk factors and inflammatory markers were also assessed. Disease activity and radiographic progression in the sacroiliac joint and spine were evaluated in the axSpA group. Multivariate linear regression analysis was performed to identify risk factors associated with TBS...

B N Smith, R N Dilger
In this review, the potential for use of soy-derived bioactive compounds as immunomodulatory feed additives in pigs is discussed. Soy is a major component of the modern U.S. swine diet in today's commercial industry, providing the bulk of dietary AA necessary for growth and production. However, soy use has generally been limited in early growth phases, during which the risks of immunological insult and disease are among the highest. Improvements of soybean processing and development of soy protein products with little to no antinutritional factors have made soy more appropriate for use in young pigs but additional processing may impact bioactive compound levels in the feed...

Objective: Class 3 semaphorins regulate diverse cellular processes relevant to the pathology of RA, including immune modulation, angiogenesis, apoptosis and invasive cell migration. Therefore, we analysed the potential role of class 3 semaphorins in the pathology of RA. Methods: Protein and mRNA expression in RA synovial tissue, SF and fibroblast-like synoviocytes (FLS) were determined by immunoblotting and quantitative PCR (qPCR). RA FLS migration and invasion were determined using wound closure and transwell invasion assays, respectively...

Cryptococcosis is an opportunistic or primary fungal infection considered to be the most prevalent fatal fungal disease worldwide. Owing to the limited number of available drugs, it is necessary to search for novel antifungal compounds. In the present work, we assessed the antifungal efficacy of three thiazole derivatives (1, 2, and 3). We conducted in vitro and in vivo assays to investigate their effects on important virulence factors, such as capsule and biofilm formation. In addition, the phagocytosis index of murine macrophages exposed to compounds 1, 2, and 3 and the in vivo efficacy of 1, 2, and 3 in Galleria mellonella infected with Cryptococcus spp...

Background and Aims: Medical management of fistulising Crohn's disease (CD) is constrained by the limited number of available therapies. We evaluated the efficacy of vedolizumab, a gut-selective α4β7 integrin antagonist approved for treating moderately to severely active CD, in a subpopulation of patients with fistulising CD who participated in the GEMINI 2 trial (NCT00783692). Methods: Exploratory analyses of data from the GEMINI 2 trial were conducted in 461 responders to 6-week vedolizumab induction therapy who received maintenance placebo (VDZ/PBO, N=153) or vedolizumab (VDZ/VDZ, N=308)...

An essential component in achieving accepted successful elimination of a disease or a pathogen involves the acquisition of quality-assured (QA) data that ultimately define the absence of infection or transmission in previously endemic areas. The acquisition of these essential data, in the case of onchocerciasis elimination, requires strong laboratory support for both testing and continuing evaluation/validation of the tools used for the required diagnostic and epidemiology procedures. There is also a need for standardization of the laboratory-based and field-based assays used across the onchocerciasis-endemic countries as well as continuing technical, fiscal and logistical support for laboratory activities...

Endemic areas that involve national or local borders present an important challenge to the success of elimination of onchocerciasis; such cross-border endemic foci require special attention to ensure that programme activities are unified. It is vital that national programmes and the committees responsible for the oversight of progress towards elimination are aware and address such issues in their current planning and programmatic activities. Although international borders that intersect endemic zones present the biggest challenge, intracountry borders (such as between administrative districts or loiasis endemic and non-loiasis areas) can also pose problems...

Tamara S Roman, Karen L Mohlke
Many genome-wide association studies (GWAS) have identified signals located in non-coding regions, and an increasing number of functional genomics annotations of regulatory elements and assays of regulatory activity have been used to investigate mechanisms. Genome-wide datasets that characterize chromatin structure help detect potential regulatory elements. Assays to experimentally assess candidate variants include transcriptional reporter assays, and recently, massively parallel reporter assays (MPRAs). Additionally, the effect of candidate regulatory elements and variants on gene expression and function can be evaluated using genomic editing with the CRISPR-Cas9 technology...

BACKGROUND: Axial spondyloarthritis (axSpA) is a progressive, chronic, inflammatory skeletal disorder affecting the spine and sacroiliac joints. Many studies have shown that neutrophils, lymphocytes, monocytes, platelets, and red blood cells (RBCs) play important roles in the inflammatory process of axSpA. Neutrophils to lymphocytes ratio (NLR) and red blood cell distribution width (RDW) have been reported to be simple and inexpensive markers to indicate the disease activity of axSpA...

AIMS: To investigate the cytoprotective effects of two sesquiterpene aminoquinones isolated from the marine sponge Dysidea fragilis, Dysidaminone H (DA8) and 3'-methylamino-avarone (DA14), we examined their effects against hydrogen peroxide (H2 O2 )-induced oxidative injury in human keratinocyte cell line and elucidated the underlying mechanisms. MAIN METHODS: Cell viability was detected using a CCK-8 assay kit. Intracellular reactive oxygen species (ROS) production was measured by fluorescence of 2, 7-Dichlorodi-hydrofluorescein diacetate (DCFH-DA)...
