Genetic factors shaping the plasma lipidome and the relations to cardiometabolic risk in children and adolescents.

Background: Lipid species are emerging as biomarkers for cardiometabolic risk in both adults and children. The genetic regulation of lipid species and their impact on cardiometabolic risk during early life remain unexplored.

Methods: Using mass spectrometry-based lipidomics, we measured 227 plasma lipid species in 1149 children and adolescents (44.

Extent of peritoneal metastases from colorectal cancer is not associated with changes in thrombin generation or fibrinolysis.

Objectives: Cancer cells can activate coagulation and inhibit fibrinolysis. The aim was to investigate the association between the burden of peritoneal metastases from colorectal cancer (PM-CRC) and biomarkers reflecting thrombin generation and fibrinolysis.

Methods: A cohort of 55 patients with PM-CRC scheduled for cytoreductive surgery.

Quantification of alcohol intake in patients with steatotic liver disease and excessive alcohol intake.

Background & Aims: Quantifying alcohol intake is crucial for subclassifying participants with steatotic liver disease (SLD) and interpreting clinical trials of alcohol-related liver disease (ALD) and metabolic and alcohol-related liver disease (MetALD). However, the accuracy of self-reported alcohol intake is considered imprecise. We compared the diagnostic and prognostic utility of self-reported alcohol intake with blood-based biomarkers of alcohol intake: phosphatidylethanol (PEth) and carbohydrate-deficient transferrin (CDT).

Development, validation, and prognostic evaluation of LiverPRO for the prediction of significant liver fibrosis in primary care: a prospective cohort study.

Background: Clinically significant liver fibrosis is associated with future adverse events in patients with steatotic liver disease. We designed a software tool for detection of clinically significant liver fibrosis in primary care.

Methods: In this prospective cohort study, we developed and validated LiverPRO using six independent cohorts from Denmark, Germany, and England that included patients from primary and secondary care with steatotic liver disease related to alcohol or metabolic dysfunction.

The steatotic liver disease burden paradox: unravelling the key role of alcohol.

The classification of steatotic liver disease (SLD) has evolved, incorporating all conditions characterized by hepatic lipid accumulation. SLD represents a continuum of disorders that are shaped by the dynamic factors of alcohol intake and cardiometabolic risk factors. This updated classification has profound implications for both the management and research of SLD, especially with the new distinct category of patients with both metabolic and alcohol-related liver disease.

Metabolic dysfunction and alcohol-related liver disease (MetALD): Position statement by an expert panel on alcohol-related liver disease.

In this position statement, we explore the intricate relationship between alcohol intake and metabolic dysfunction in the context of the 2023 nomenclature update for steatotic liver disease (SLD). Recent and lifetime alcohol use should be accurately assessed in all patients with SLD to facilitate classification of alcohol use in grams of alcohol per week. Alcohol biomarkers (i.

Fecal microbial load is a major determinant of gut microbiome variation and a confounder for disease associations.

The microbiota in individual habitats differ in both relative composition and absolute abundance. While sequencing approaches determine the relative abundances of taxa and genes, they do not provide information on their absolute abundances. Here, we developed a machine-learning approach to predict fecal microbial loads (microbial cells per gram) solely from relative abundance data.

Steatotic liver disease.

Steatotic liver disease is the overarching term for conditions characterised by abnormal lipid accumulation in the liver (liver or hepatic steatosis). Steatotic liver disease encompasses what was previously termed non-alcoholic fatty liver disease (NAFLD), which is now called metabolic dysfunction-associated steatotic liver disease (MASLD). Additionally, steatotic liver disease includes alcohol-related liver disease (ALD) and MetALD, the new classification for the overlap between MASLD and ALD, and rare causes of liver steatosis.

Hepatocellular Cancer Surveillance in Patients with Advanced Chronic Liver Disease.

Background: Patients with advanced chronic liver disease (ACLD) are at high risk of developing hepatocellular carcinoma (HCC). Therefore, biannual surveillance is recommended. This large-scale multicenter study aimed to stratify the risk of HCC development in ACLD.

Longitudinal Evaluation of Individuals With Severe Alpha-1 Antitrypsin Deficiency (Pi∗ZZ Genotype).

Background & Aims: Homozygous Pi∗Z mutation in alpha-1 antitrypsin (Pi∗ZZ genotype) predisposes to pulmonary loss-of-function and hepatic gain-of-function injury. To facilitate selection into clinical trials typically targeting only 1 organ, we systematically evaluated an international, multicenter, longitudinal, Pi∗ZZ cohort to uncover natural disease course and surrogates for future liver- and lung-related endpoints.

Methods: Cohort 1 recruited 737 Pi∗ZZ individuals from 25 different centers without known liver comorbidities who received a baseline clinical and laboratory assessment as well as liver stiffness measurement (LSM).

Transforming steatotic liver disease management: The emerging role of GLP-1 receptor agonists.

Chronic liver disease is a major cause of mortality, with approximately 2 million deaths worldwide each year, and it poses a significant economic burden. The most common cause of chronic liver disease in the United States and Europe is steatotic liver disease (SLD), which includes metabolic dysfunction-associated SLD, metabolic dysfunction and alcohol-associated SLD, and alcohol-associated liver disease (ALD). Effective treatment of these conditions is essential to reduce the liver disease burden, with promising approaches including treating cardiometabolic risk factors and excessive alcohol intake.

Preoperative virtual surgical planning and the use of 3D-printed patient-specific models and cutting guides are increasingly being used in the reconstruction of mandibular defects with a free bone flap. This technology offers several advantages over conventional surgery, such as reduced operating time, reduced bone flap ischaemia time, and the ability to perform more complex and precise reconstructions. This review presents the evidence supporting 3D-assisted surgery for mandibular defect reconstruction and discusses the utilisation of commercial vendors versus in-house 3D-printing solutions.

Lipid profiling identifies modifiable signatures of cardiometabolic risk in children and adolescents with obesity.

Pediatric obesity is a progressive, chronic disease that can lead to serious cardiometabolic complications. Here we investigated the peripheral lipidome in 958 children and adolescents with overweight or obesity and 373 with normal weight, in a cross-sectional study. We also implemented a family-based, personalized program to assess the effects of obesity management on 186 children and adolescents in a clinical setting.

State of the art and the future of microbiome-based biomarkers: a multidisciplinary Delphi consensus.

Although microbiome signatures have been identified in various contexts (ie, pathogenesis of non-communicable diseases and treatment response), qualified microbiome-based biomarkers are currently not in use in clinical practice. The Human Microbiome Action consortium initiated a Delphi survey to establish a consensus on the needs, challenges, and limitations in developing qualified microbiome-based biomarkers. The questionnaire was developed by a scientific committee via literature review and expert interviews.

Implementation of In-house Computer-aided Design and Manufacturing for Accelerated Free Fibula Flap Reconstruction of Mandibular Defects in Cancer Patients.

Background: Computer-aided design and manufacturing (CAD/CAM) is widely adopted for optimizing microsurgical reconstruction of mandibular defects. However, commercial solutions are hampered by costs and lengthy lead times, with the latter being problematic in cancer surgery. This study aimed to investigate the efficiency of an in-house CAD/CAM service for expeditious planning and execution of free fibula mandibular reconstruction in head and neck cancer patients.

Development and external validation of a model to predict multidrug-resistant bacterial infections in patients with cirrhosis.

Unlabelled: With the increasing rate of infections caused by multidrug-resistant organisms (MDRO), selecting appropriate empiric antibiotics has become challenging. We aimed to develop and externally validate a model for predicting the risk of MDRO infections in patients with cirrhosis.

Methods: We included patients with cirrhosis and bacterial infections from two prospective studies: a transcontinental study was used for model development and internal validation (n = 1302), and a study from Argentina and Uruguay was used for external validation (n = 472).

Alcohol consumption and liver phenotype of individuals with alpha-1 antitrypsin deficiency.

Background And Aims: Alpha-1 antitrypsin deficiency is an inherited disorder caused by alpha-1 antitrypsin (AAT) mutations. We analysed the association between alcohol intake and liver-related parameters in individuals with the heterozygous/homozygous Pi*Z AAT variant (Pi*MZ/Pi*ZZ genotype) found in the United Kingdom Biobank and the European Alpha1 liver consortium.

Methods: Reported alcohol consumption was evaluated in two cohorts: (i) the community-based United Kingdom Biobank (17 145 Pi*MZ, 141 Pi*ZZ subjects, and 425 002 non-carriers [Pi*MM]); and (ii) the European Alpha1 liver consortium (561 Pi*ZZ individuals).

Use of HBsAg-positive donors in liver transplantation: An ILTS-EASL-AASLD multisociety survey.

The gap between organ supply and demand in liver transplantation remains large in most parts of the world. One strategy to increase the donor pool is to use grafts infected with HCV, HBV, and/or HIV viruses. We aimed to explore the current use of HBsAg-positive liver grafts worldwide.

The interplay between birth weight and obesity in determining childhood and adolescent cardiometabolic risk.

Background: Birth weight (BW) is associated with risk of cardiometabolic disease (CMD) in adulthood, which may depend on the state of obesity, in particular if developed at a young age. We hypothesised that BW and a polygenic score (PGS) for BW were associated with cardiometabolic risk and related plasma protein levels in children and adolescents. We aimed to determine the modifying effect of childhood obesity on these associations.
