Identifying predictors of inflammatory bowel disease (IBD) outcome in order to optimize individual patient management in has become an important goal. We aimed to describe the long-term outcome of pediatric Crohn disease (CD) patients and identify risk factors for complicated behavior.

Pediatric CD patients diagnosed between 1998 and 2014, with long-term follow-up were included. Baseline data; age, gender, weight/height/BMI percentiles, and family history of IBD. Disease characteristics (Paris classification), laboratory testing, imaging and treatment were documented. Outcome data; evidence of stricturing or penetrating disease, hospitalizations, surgical intervention, malignancies, and mortality.

Of 93 patients included, mean age at diagnosis 13.5 (±3.2), 51 (55%) male, median follow-up 10.3 years (±4 SD(. Disease location at diagnosis 29 (31.2%) distal ileum, 17 (18.3%) colonic, 40 (43.0%) ileo-colonic. Seven (7.5%) had upper gastrointestinal and 36 (38.7%) perianal involvement. Behavior at diagnosis, 68 (73.1%) inflammatory (B1), and 25 (26.9%) complicated [(B2 (stricturing) and/or B3 (penetrating)]. Twenty (23.2%) of B1 evolved to B2 and/or B3, thus by the end of follow-up 45 (48.4%) had complicated behavior. Sixty-seven (72%) were hospitalized, 20 (21.5%) underwent surgery, two developed malignancy with no mortalities. In a logistic regression model, growth delay (hazard ratio [HR], 5.02 [1.10-22.85], P = 0.037) and low albumin levels (HR, 3.97 [1.32-11.97], P = 0.014) at diagnosis were predictors of complicated disease in adulthood.

Over a quarter of pediatric Crohn disease patients present with complicated behavior. During follow-up another quarter progress to complicated disease behavior. Delayed growth and low albumin at diagnosis predict progression.

In children with biliary atresia and portal hypertension, progression to gastroesophageal varices carrying a risk of bleeding depends on age, total serum bilirubin concentration and initial endoscopic features. We report an attempt to use these factors for early detection of high-risk varices (HRVs).

Based on different combinations of these factors, a model was set to estimate the probabilities of emergence of HRVs at various time intervals. A 10% probability was chosen to set the date of the next endoscopy in children who did not display HRVs initially. A total of 113 children without HRVs who underwent their first endoscopy before age 8 in 2013-2020 were included. A comparison was made with children seen during the period 1990-2012 when this model was not used.

In all, 65 of the 113 children underwent one to five additional endoscopies at dates set according to the model. The emergence of HRVs was recorded in 22 children after a mean interval of 14 months and was managed by endoscopic primary prophylaxis in all but one who underwent liver transplantation. Three other children bled before the next planned endoscopy. Dynasore mw Compared with 175 children of the same age ranges without HRVs in the period 1990-2012, the use of the model was associated with a faster detection of HRVs with a lower number of endoscopic procedures (P  = 0.0022 and P  = 0.023, respectively).

The results suggest that the model reported may be a useful tool for the early detection of HRVs to allow primary prophylaxis of bleeding.

Tissue-transglutaminase antibodies (TGA) may be used to diagnose celiac disease (CD) without biopsy in selected cases. We aimed to investigate real-life performance of a CD serology automated analyzer (Bioplex2200), and to explore the correlation between TGA levels and intestinal biopsies in children.

A retrospective review was performed in 2 pediatric gastroenterological centers, between November 1, 2018 and April 1, 2020 and included patients with both TGA serology testing and duodenal biopsies. Retrieved data included patients' demographics, medical background, TGA levels, and biopsy results.

Overall, 538 children were evaluated, 256 with positive TGA (68.4% girls, median age 6.4 years), and 282 with negative TGA (53.9% girls, median age 13.4 years). Among patients with positive TGA, intestinal biopsies confirmed CD in 219 (85.5%). Overall, positive serology with normal histology was found in 14.5% of the cohort, with 52%; 21.6%; 21.1%; and 4.2% in TGA ranges of 1 to 3 times upper limit of normal (ULN); 3 to 5 ULN; 5 to 10 ULN; and above 10 times ULN, respectively, P < 0.001. Area under the receiver-operating characteristic curve (AUC) was 0.963 (95% CI 0.947-0.980). Among patients with positive TGA, 216 (84.4%) had positive anti-endomysial antibodies. In this sub-group, the overall diagnostic performance was inferior, with AUC of 0.737 (95% CI 0.834-0.839).

The Multiplex TGA assay had a very high diagnostic accuracy in real-life. Among patients with positive TGA, adding EMA did not improve the diagnostic performance of the test. False-positive rates differed between different ranges of TGA and were low with TGA above 10 times ULN.

Incidental liver lesions are identified in children without underlying liver disease or increased risk of hepatic malignancy in childhood. Clinical and imaging evaluation of incidental liver lesions can be complex and may require a multidisciplinary approach. This review aims to summarize the diagnostic process and follow-up of incidental liver lesions based on review of the literature, use of state-of-the-art imaging, and our institutional experience. Age at presentation, gender, alpha fetoprotein levels, tumor size, and imaging characteristics should all be taken into consideration to optimize diagnosis process. Some lesions, such as simple liver cyst, infantile hemangioma, focal nodular hyperplasia (FNH), and focal fatty lesions, have specific imaging characteristics. Recently, contrast-enhanced ultrasound (CEUS) was Food and Drug Administration (FDA)-approved for the evaluation of pediatric liver lesions. CEUS is most specific in lesions smaller than 3 cm and is most useful in the diagnosis of infantiletoprotein (AFP) should be performed to confirm the stability of lesions when the diagnosis cannot be determined, and whenever biopsy is not feasible.Dengue virus (DENV) is a mosquito-borne RNA virus, which infects nearly 3.97 billion people every year in the tropical and subtropical regions of the world. DENV infections can range from unrecognizable illnesses to a spectrum of clinical manifestations such as dengue fever (DF), and more severe and potentially lethal dengue hemorrhagic fever (DHF). The variability of clinical manifestations induced by DENV can be attributed to a variety of extrinsic and intrinsic factors including virulence of the DENV strains and host genetic factors influencing the immune response. Interferon gamma (IFN-Y) is one of the critical immunomodulators implicated in DENV infection, and recent case-control association studies examined the role of +874 T/A polymorphism (rs2430561) of the IFN-Y gene in dengue clinical outcomes. Since the results of the association studies on DENV infection and IFN-Y +874 T/A polymorphism were inconsistent, we performed a meta-analysis to derive a more precise estimate of the association. Searching trred risk to dengue, albeit with varied clinical outcomes, and revealed a protective role of the heterozygous genotype against DENV infection.

For patients with high bleeding risk, the BioFreedom stent is safer and more effective than a bare metal stent. However, at the one-year follow-up of the SORT OUT IX trial, the BioFreedom stent did not meet the criteria for non-inferiority for target lesion failure (TLF) when compared with the Orsiro stent and had a higher incidence of target lesion revascularisation (TLR).

The aim of the study was to compare the two-year outcomes following coronary implantation of the BioFreedom or the Orsiro stents in all-comer patients.

The Scandinavian Organization for Randomized Trials with Clinical Outcome (SORT OUT) IX trial is a prospective, multicentre, randomised clinical trial comparing the BioFreedom and the Orsiro stents. The primary endpoint, TLF, was a composite of cardiac death, myocardial infarction (MI; not related to other lesions) and TLR.

A total of 1,572 patients were randomised to treatment with the BioFreedom stent and 1,579 patients with the Orsiro stent. At two-year follow-up, TLF was 7.8% in the BioFreedom and 6.3% in the Orsiro stent groups (rate ratio [RR] 1.23, 95% confidence interval [CI] 0.94-1.61). Risks of cardiac death, MI and definite stent thrombosis did not differ significantly between the groups, whereas more patients in the BioFreedom group had TLR (5.1% vs 2.6%; RR 1.98, 95% CI 1.26-2.89) attributable to a higher risk of TLR within the first year (3.5% vs 1.3%; RR 2.77, 95% CI 1.66-4.62).

At two years, there were no significant differences between the BioFreedom and Orsiro stents for TLF. TLR was significantly higher with the BioFreedom stent due to higher risk of TLR within the first year.

Epithelial Na+ channel (ENaC) function is critical to systems responsible for extracellular fluid homeostasis and gas exchange. ENaC is activated by cleavage at multiple specific extracellular polybasic sites, releasing inhibitory tracts from the channel's α and γ subunits. We found that proximal and distal polybasic tracts in ENaC subunits coevolved, consistent with the dual cleavage requirement for activation observed in mammals. Polybasic tract pairs evolved with the terrestrial migration and the appearance of lungs, coincident with the ENaC activator aldosterone, and appeared independently in the α and γ subunits. In summary, sites within ENaC for protease activation developed in vertebrates when renal Na+ conservation and alveolar gas exchange were required for terrestrial survival.Dark caves lacking primary productivity can expose subterranean animals to hypoxia. We used the surface-dwelling (surface fish) and cave-dwelling (cavefish) morphs of Astyanax mexicanus as a model for understanding the mechanisms of hypoxia tolerance in the cave environment. Primitive hematopoiesis, which is restricted to the posterior lateral mesoderm in other teleosts, also occurs in the anterior lateral mesoderm in Astyanax, potentially pre-adapting surface fish for hypoxic cave colonization. Cavefish have enlarged both hematopoietic domains and develop more erythrocytes than surface fish, which are required for normal development in both morphs. Laboratory-induced hypoxia suppresses growth in surface fish but not in cavefish. Both morphs respond to hypoxia by overexpressing hypoxia-inducible factor 1 (hif1) pathway genes, and some hif1 genes are constitutively upregulated in normoxic cavefish to similar levels as in hypoxic surface fish. We conclude that cavefish cope with hypoxia by increasing erythrocyte development and constitutive hif1 gene overexpression.
