Tobacco is a Leading Risk Factor for Liver and Extrahepatic Cancers in Patients With Liver Cirrhosis: A Prospective Cohort Study.

Background & Aims: This study aims to assess the incidence and characteristics of all cancers, hepatocellular carcinoma (HCC), and extrahepatic cancers in patients with cirrhosis of various etiologies.

Methods: Prospective cohort study in patients with cirrhosis but no cancer, followed every 6-9 months through the HCC early detection program. Cancer incidence was compared with Spanish population data to calculate standardized incidence ratios (SIR), and cumulative incidence was calculated separately for cancer and competing events.

Correlation of endoscopic ultrasound-guided portal pressure gradient measurements with hepatic venous pressure gradient: a prospective study.

Background: Hepatic venous portal gradient (HVPG) measurement remains the gold standard for estimating portal pressure gradient (PPG). This study aimed to evaluate the correlation between endoscopic ultrasound (EUS)-guided PPG and HVPG in patients with chronic portal hypertension.

Methods: Patients with chronic portal hypertension in whom HVPG assessment was clinically indicated were invited to undergo transjugular HVPG and EUS-PPG with a 22-G needle in separate sessions for comparison.

Experimental investigation of the effect of tebuconazole on three biomarkers of innate immunity in the house sparrow (Passer domesticus).

Triazoles are among the most widely used fungicides in the world due to their efficacy against fungal crop diseases and their broad spectrum of action. Intensive use of triazoles has resulted in residual contamination in different compartments of agroecosystems and exposes non-target species to potential sublethal effects. Triazoles are known to be immunomodulators in medicine and therapeutic treatments, but very little data is available on their potential effect on immune parameters of non-target vertebrate species living in agroecosystems.

Plasma lipid metabolites as potential biomarkers for identifying individuals at risk of obesity-induced metabolic complications.

Lipidomics studies have indicated an association between obesity and lipid metabolism dysfunction. This study aimed to evaluate and compare cardiometabolic risk factors, and the lipidomic profile in adults and older people. A cross-sectional study was conducted with 72 individuals, divided into two sex and age-matched groups: obese (body mass index-BMI ≥ 30 kg/m; n = 36) and non-obese (BMI < 30 kg/m; n = 36).

Chronic exposure to tebuconazole alters thyroid hormones and plumage quality in house sparrows (Passer domesticus).

Triazoles belong to a family of fungicides that are ubiquitous in agroecosystems due to their widespread use in crops. Despite their efficiency in controlling fungal diseases, triazoles are also suspected to affect non-target vertebrate species through the disruption of key physiological mechanisms. Most studies so far have focused on aquatic animal models, and the potential impact of triazoles on terrestrial vertebrates has been overlooked despite their relevance as sentinel species of contaminated agroecosystems.

Immune changes over time and survival in patients with cirrhosis treated with non-selective beta-blockers: A prospective longitudinal study.

Background: Treatment with non-selective beta-blockers (NSBB) has been associated with anti-inflammatory and anti-cancer effects in patients with cirrhosis. This study aims to analyze the impact of chronic NSBB treatment on immune activation and disease progression in stable outpatients with cirrhosis.

Methods: In this prospective follow-up of 150 patients with cirrhosis, 39 received treatment with NSBB.

Are Phosphatidylcholine and Lysophosphatidylcholine Body Levels Potentially Reliable Biomarkers in Obesity? A Review of Human Studies.

Phosphatidylcholines (PCs) are the major components of biological membranes in animals and are a class of phospholipids that incorporate choline as a headgroup. Lysophosphatidylcholines (LPCs) are a class of lipid biomolecules derived from the cleavage of PCs, and are the main components of oxidized low-density lipoproteins (oxLDLs) that are involved in the pathogenesis of atherosclerosis. Since obesity is associated with a state of chronic low-grade inflammation, one can anticipate that the lipidomic profile changes in this context and both PCs and LPCs are gaining attention as hypothetically reliable biomarkers of obesity.

Evidence of environmental transfer of tebuconazole to the eggs in the house sparrow (Passer domesticus): An experimental study.

Triazole compounds are among the most widely used fungicides in agroecosystems to protect crops from potential fungal diseases. Many farmland birds spend a significant part of their life cycle in agroecosystems, which may chronically expose them to pesticides. We experimentally tested whether exposure to environmental concentrations of tebuconazole could induce a contamination of the eggs in an agroecosystem sentinel species, the house sparrow (Passer domesticus).

Experimental Exposure to Tebuconazole Affects Metabolism and Body Condition in a Passerine Bird, the House Sparrow (Passer domesticus).

Triazole compounds are among the most widely used fungicides in agroecosystems to protect crops from potential fungal diseases. Triazoles are suspected to have an impact on nontarget species due to their interactions with nonfungal sterol synthesis, and wild birds are likely to be contaminated by triazole fungicides because many of them live in agroecosystems. We experimentally tested whether exposure to environmental concentrations of a triazole could alter key integrative traits (metabolic rates and body condition) of an agroecosystem sentinel species, the house sparrow (Passer domesticus).

Hyperdense Artery Sign in Patients With Acute Ischemic Stroke-Automated Detection With Artificial Intelligence-Driven Software.

Background: Hyperdense artery sign (HAS) on non-contrast CT (NCCT) can indicate a large vessel occlusion (LVO) in patients with acute ischemic stroke. HAS detection belongs to routine reporting in patients with acute stroke and can help to identify patients in whom LVO is not initially suspected. We sought to evaluate automated HAS detection by commercial software and compared its performance to that of trained physicians against a reference standard.

Textbook outcome among patients undergoing enhanced recovery after liver transplantation stratified by risk. A single-center retrospective observational cohort study.

Background & Aims: Liver transplantation (LT) is one of the most complex surgical procedures. Enhanced recovery after surgery (ERAS) aims to reduce the risk of postoperative complications. When patients achieve all desirable outcomes after a procedure, they are considered to have experienced a textbook outcome (TO).

Comparative toxicity of conventional and unconventional oils during rainbow trout (Oncorhynchus mykiss) embryonic development: From molecular to health consequences.

Canadian freshwater ecosystems are vulnerable to oil spills from pipelines, which contain mostly diluted bitumen. This study aimed to compare the toxicity of a dilbit and a conventional oil on developing rainbow trout. A total of five exposure scenarios were performed, from 10 to 43 days, using water-accommodated fraction (WAF) with an initial loading of 1:9 oil to water ratio (w/v) in a range of dilutions from 0.

Non-alcoholic fatty liver disease is associated with bacterial translocation and a higher inflammation response in psoriatic patients.

Psoriasis and non-alcoholic fatty liver disease (NAFLD) are both inflammatory diseases. The study objective was to estimate the risk of NAFLD, non-alcoholic steatohepatitis, and liver fibrosis (by liver stiffness and liver biopsy) in patients with psoriasis and to determine the epidemiological, clinical, immunological (TNF-α, IL-2, IL-6, IL-12, IL-17, IL-23, and TGF-β) characteristics, and bacterial translocation. Of the 215 psoriatic patients included, 91 presented NAFLD (prevalence: 42.

Enhanced recovery after low- and medium-risk liver transplantation. A single-center prospective observational cohort study.

Background & Aims: Few studies have fully applied an enhanced recovery after surgery (ERAS) protocol to liver transplantation (LT). Our aim was to assess the effects of a comprehensive ERAS protocol in our cohort of low- and medium-risk LT patients.

Methods: The ERAS protocol included pre-, intra-, and post-operative steps.

Functionality of beta-adrenergic receptors in patients with cirrhosis treated chronically with non-selective beta-blockers.

Background: In patients with cirrhosis, beta-adrenoceptors expressed on peripheral blood mononuclear cells have a reduced response to catecholamine stimulation. This study aimed to determine if chronic treatment with beta-blockers influences these changes.

Methods: Blood samples were collected from patients with cirrhosis treated in outpatient clinics.

Bacterial antigen translocation and age as BMI-independent contributing factors on systemic inflammation in NAFLD patients.

Background & Aims: Low-grade systemic inflammation is a crucial landmark in NAFLD favouring disease progression and comorbidities. We evaluated the input of circulating bacterial antigens on systemic markers of inflammation in NAFLD patients.

Patients & Methods: Multicenter cross-sectional study including consecutive patients with biopsy-proven NAFLD.

Identification of rumen microbial biomarkers linked to methane emission in Holstein dairy cows.

Mitigation of greenhouse gas emissions is relevant for reducing the environmental impact of ruminant production. In this study, the rumen microbiome from Holstein cows was characterized through a combination of 16S rRNA gene and shotgun metagenomic sequencing. Methane production (CH ) and dry matter intake (DMI) were individually measured over 4-6 weeks to calculate the CH yield (CH y = CH /DMI) per cow.

Circulating levels of butyrate are inversely related to portal hypertension, endotoxemia, and systemic inflammation in patients with cirrhosis.

Short-chain fatty acids (SCFAs) are gut microbiota-derived products that participate in maintaining the gut barrier integrity and host's immune response. We hypothesize that reduced SCFA levels are associated with systemic inflammation, endotoxemia, and more severe hemodynamic alterations in cirrhosis. Patients with cirrhosis referred for a hepatic venous pressure gradient (HVPG) measurement ( = 62) or a transjugular intrahepatic portosystemic shunt placement ( = 12) were included.

Nonalcoholic fatty liver disease puts patients with psoriasis at greater cardiovascular risk.

Background/objective: Psoriasis and nonalcoholic fatty liver disease (NAFLD) are inflammatory diseases associated with increased cardiovascular risk, but no studies have evaluated cardiovascular risk in patients with both. The objective was to assess cardiovascular risk in patients with psoriasis and NAFLD.

Material And Methods: Cross-sectional, single-centre study in patients with moderate to severe psoriasis.

Bacterial DNA translocation contributes to systemic inflammation and to minor changes in the clinical outcome of liver transplantation.

Bacterial (bact)DNA is an immunogenic product that frequently translocates into the blood in cirrhosis. We evaluated bactDNA clearance in patients undergoing liver transplantation (LT) and its association with inflammation and clinically relevant complications. We prospectively included patients consecutively admitted for LT in a one-year follow-up study.

Differential expression of long non-coding RNAs are related to proliferation and histological diversity in follicular lymphomas.

Long non-coding RNAs (lncRNAs) comprise a family of non-coding transcripts that are emerging as relevant gene expression regulators of different processes, including tumour development. To determine the possible contribution of lncRNA to the pathogenesis of follicular lymphoma (FL) we performed RNA-sequencing at high depth sequencing in primary FL samples ranging from grade 1-3A to aggressive grade 3B variants using unpurified (n = 16) and purified (n = 12) tumour cell suspensions from nodal samples. FL grade 3B had a significantly higher number of differentially expressed lncRNAs (dif-lncRNAs) with potential target coding genes related to cell cycle regulation.

Unsupervised GRN Ensemble.

Inferring gene regulatory networks from expression data is a very challenging problem that has raised the interest of the scientific community. Different algorithms have been proposed to try to solve this issue, but it has been shown that different methods have some particular biases and strengths, and none of them is the best across all types of data and datasets. As a result, the idea of aggregating various network inferences through a consensus mechanism naturally arises.

Evaluation of factors that may influence in the insufficient weight loss in patients after two years of Roux-en-Y gastric bypass.

Introduction: bariatric surgery is a favorable option for the treatment of obesity, resulting in long-term weight loss.

Objectives: to analyze whether feeding behavior, evaluated by caloric intake, dietary preferences and tolerance, can be considered as a determinant factor for weight loss in obese patients submitted to Roux-en-Y gastric bypass (RYGB).

Methods: cross-sectional study of 105 patients with at least two years post-RYGB surgery with a preoperative body mass index (BMI) of ≥ 35 kg/m².

Can Deep Learning Improve Genomic Prediction of Complex Human Traits?

The genetic analysis of complex traits does not escape the current excitement around artificial intelligence, including a renewed interest in "deep learning" (DL) techniques such as Multilayer Perceptrons (MLPs) and Convolutional Neural Networks (CNNs). However, the performance of DL for genomic prediction of complex human traits has not been comprehensively tested. To provide an evaluation of MLPs and CNNs, we used data from distantly related white Caucasian individuals ( ∼100k individuals, ∼500k SNPs, and = 1000) of the interim release of the UK Biobank.

Norfloxacin is more effective than Rifaximin in avoiding bacterial translocation in an animal model of cirrhosis.

Background & Aims: Norfloxacin administration is useful in preventing bacterial infections in cirrhosis but associated to the generation of resistant species. Rifaximin is known to reach high concentrations in the intestinal lumen without generating relevant resistance in the intestinal flora. Our aim was to compare the effect of Norfloxacin and Rifaximin on intestinal flora composition, bacterial translocation and survival in cirrhotic rats.
