Apolipoprotein CIII correlates with lipoproteins in the fed state and is not regulated by leptin administration in states of hypoleptinemia induced by acute or chronic energy deficiency: Results from two randomised controlled trials.

Background: Medications targeting the leptin and Apolipoprotein CIII (APOC3) pathways are currently under development for the treatment of hypertriglyceridaemia. Given that both pathways are implicated in triglyceride regulation, it is unknown whether they function independently or interact under physiological conditions and under acute or long-term energy deficiency.

Methods: APOC3 levels and their association with circulating lipids and lipoproteins were evaluated in the context of two randomised controlled studies.

Proteomic and Metabolomic Signatures in Prediabetes Progressing to Diabetes or Reversing to Normoglycemia Within 1 Year.

Objective: Progression of prediabetes to type 2 diabetes has been associated with β-cell dysfunction, whereas its remission to normoglycemia has been related to improvement of insulin sensitivity. To understand the mechanisms and identify potential biomarkers related to prediabetes trajectories, we compared the proteomics and metabolomics profile of people with prediabetes progressing to diabetes or reversing to normoglycemia within 1 year.

Research Design And Methods: The fasting plasma concentrations of 1,389 proteins and the fasting, 30-min, and 120-min post-oral glucose tolerance test (OGTT) plasma concentrations of 152 metabolites were measured in up to 134 individuals with new-onset diabetes, prediabetes, or normal glucose tolerance.

Simplifying coronary artery disease risk stratification: development and validation of a questionnaire-based alternative comparable to clinical risk tools.

Background: Coronary artery disease (CAD) comprises one of the leading causes of morbidity and mortality both in the European population and globally. All established clinical risk stratification scores and models require blood lipids and physical measurements. The latest reports of the European Commission suggest that attracting health professionals to collect these data can be challenging, both from a logistic and cost perspective, which limits the usefulness of established models and makes them unsuitable for population-wide screening in resource-limited settings, i.

Effect of glucagon-like peptide-1 receptor agonists and co-agonists on body composition: Systematic review and network meta-analysis.

Background And Aims: While glucagon-like peptide-1 receptor agonists (GLP-1RAs) effectively reduce body weight, their impact on lean mass remains uncertain. This meta-analysis evaluated the effects of GLP-1RAs and GLP-1/GIP receptor dual agonists (GLP-1/GIP-RAs) on body composition, focusing on total weight, fat mass, and lean mass in adults with diabetes and/or overweight/obesity.

Methods: A systematic search of Medline, Embase, and the Cochrane Library was conducted through November 12, 2024.

Renin-independent aldosteronism and metabolic dysfunction-associated steatotic liver disease and cirrhosis: A genetic association study.

Background & Aims: Renin-independent aldosteronism (RIA) refers to a spectrum of autonomous aldosterone hypersecretion. We aimed to explore the genetical relationship between RIA and metabolic dysfunction-associated steatotic liver disease (MASLD) and cirrhosis.

Methods: We included 125357 participants from the cohort of United Kingdom Biobank.

Lipoprotein (a) in the Full Spectrum of Metabolic Dysfunction-associated Steatotic Liver Disease: Evidence From Histologically and Genetically Characterized Cohorts.

Background & Aims: Lipoprotein(a) (Lp(a)) is an emerging biomarker for cardiometabolic factors. We studied the role of Lp(a) in the full spectrum of metabolic dysfunction-associated steatotic liver disease (MASLD).

Methods: Three independent analyses were implemented using a multi-center, cross-sectional, liver biopsy-based study (n = 332) (Study 1) and the UK Biobank prospective study (n = 270,004) (Study 2; median follow-up, 12.

Regulation of proglucagon derived peptides by carbohydrate and protein ingestion in young healthy males-A randomized, double-blind, cross-over trial.

Background & Aims: The ingestion of macronutrients triggers the release of several incretin peptides from the gastrointestinal system, which have both insulinotropic and satiety-inducing properties. The effect of the meal's macronutrient content on the secretion of these peptides has not been adequately studied, particularly concerning the secretion of the newly characterized proglucagon-derived peptides (PGDPs). We aimed to examine the effect of a meal's macronutrient content, specifically its protein versus carbohydrate content, on postprandial PGDPs responses in healthy men.

The Combined Administration of Eicosapentaenoic Acid (EPA) and Gamma-Linolenic Acid (GLA) in Experimentally Induced Colitis: An Experimental Study in Rats.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease with limited effective treatments, prompting the need for investigation of novel therapeutic approaches. Eicosapentaenoic acid (EPA) and gamma-linolenic acid (GLA) have demonstrated potential anti-inflammatory properties, but their combined effects on UC have not been thoroughly investigated. This study aimed to evaluate the effect of the combined administration of EPA and GLA on clinical and histopathologic features of experimental UC models.

Perineal Rectosigmoidectomy (Altemeier's Procedure) in the Treatment of Strangulated Rectal Prolapse: A Case Series and Literature Review.

Background: Rectal prolapse (RP) predominantly affects women over the age of 50 and presents as mucosal, internal, or full thickness prolapse. Strangulated rectal prolapse requires immediate medical intervention, and surgical treatment options include both abdominal and perineal approaches. We aim to present a case series of perineal rectosigmoidectomy performed urgently due to strangulation and argue that Altemeier's procedure is the preferred method for treating strangulated rectal prolapse.

Global burden of disease attributable to metabolic risk factors in adolescents and young adults aged 15-39, 1990-2021.

Background: Metabolic risk factors are a significant cause of global burden among adolescents and young adults, but there is a lack of attention to the burden attributable to these metabolic risk factors globally.

Aims: This study aims to provide comprehensive estimates of five important metabolic risk factors and the attributable disease burden in people aged 15-39 years from 1990 to 2021, based on the Global Burden of Disease Study (GBD) database.

Methods: Global total deaths and disability-adjusted life years (DALYs) were used to describe the burden attributable to five common metabolic risk factors, including high fasting plasma glucose (FPG), high low-density lipoprotein cholesterol (LDL-C), high systolic blood pressure (SBP), high body mass index (BMI), and kidney dysfunction, in adolescents and young adults.

Accurate non-invasive detection of MASH with fibrosis F2-F3 using a lightweight machine learning model with minimal clinical and metabolomic variables.

Background: There are no known non-invasive tests (NITs) designed for accurately detecting metabolic dysfunction-associated steatohepatitis (MASH) with liver fibrosis stages F2-F3, excluding cirrhosis-the FDA-defined range for prescribing Resmetirom and other drugs in clinical trials. We aimed to validate and re-optimize known NITs, and most importantly to develop new machine learning (ML)-based NITs to accurately detect MASH F2-F3.

Methods: Clinical and metabolomic data were collected from 443 patients across three countries and two clinic types (metabolic surgery, gastroenterology/hepatology) covering the entire spectrum of biopsy-proven MASH, including cirrhosis and healthy controls.

Inflammation in atherosclerosis: pathophysiology and mechanisms.

Atherosclerosis imposes a heavy burden on cardiovascular health due to its indispensable role in the pathogenesis of cardiovascular disease (CVD) such as coronary artery disease and heart failure. Ample clinical and experimental evidence has corroborated the vital role of inflammation in the pathophysiology of atherosclerosis. Hence, the demand for preclinical research into atherosclerotic inflammation is on the horizon.

Thoracoabdominal approach to large adrenal tumors - when laparoscopic adrenalectomy is not enough: a retrospective four-year study.

Laparoscopic adrenalectomy is considered to be the gold standard approach in the field of adrenal surgery. This technique offers advantages of great importance compared to variant laparotomy techniques. Notwithstanding, a technique that needs to be mentioned is the thoracoabdominal approach which facilitates the anatomic exposure of the retroperitoneum, adrenal gland, and great vessels and is strongly recommended for the surgery of large, malignant adrenal tumors.

Noninvasive Hepatic Steatosis and Fibrosis Indices Differentially Predict Mortality in the Adult Korean Population.

Background & Aims: Because the association of hepatic fibrosis and steatosis non-invasive indices with mortality remain controversial, their association with all-cause, cardiovascular-, cancer-, and liver-related mortality was evaluated in the Korean population.

Methods: In this registry-based, cohort study, data were retrieved from the Korea National Health and Nutrition Examination Survey and mortality data from the Korean Cause of Death data registry; 40,491 individuals followed-up for a median of 8.6 years.

Evidence from clinical studies of leptin: current and future clinical applications in humans.

Leptin has been established as the prototype adipose tissue secreted hormone and as a major regulator of several human physiology functions. Here, we are primarily reviewing the findings from studies in humans involving leptin administration. We are describing the metabolic, endocrine and immunologic effects of leptin replacement in conditions of leptin deficiency, such as short-term fasting in healthy individuals, relative energy deficiency in sports (REDS), congenital leptin deficiency (CLD), generalized (GL) and partial lipodystrophy (PL), HIV-associated lipodystrophy (HIV-L) and of leptin treatment in conditions of leptin excess (common obesity, type 2 diabetes, steatotic liver disease).

The impact of weight loss on fat-free mass, muscle, bone and hematopoiesis health: Implications for emerging pharmacotherapies aiming at fat reduction and lean mass preservation.

Similar to bariatric surgery, incretin receptor agonists have revolutionized the treatment of obesity, achieving up to 15-25 % weight loss in many patients, i.e., at a rate approaching that achieved with bariatric surgery.

Leptin physiology and pathophysiology in energy homeostasis, immune function, neuroendocrine regulation and bone health.

Since its discovery and over the past thirty years, extensive research has significantly expanded our understanding of leptin and its diverse roles in human physiology, pathophysiology and therapeutics. A prototypical adipokine initially identified for its critical function in appetite regulation and energy homeostasis, leptin has been revealed to also exert profound effects on the hypothalamic-pituitary-gonadal, thyroid, adrenal and growth hormone axis, differentially between animals and humans, as well as in regulating immune function. Beyond these roles, leptin plays a pivotal role in significantly affecting bone health by promoting bone formation and regulating bone metabolism both directly and indirectly through its neuroendocrine actions.

Apolipoprotein C-III in association with metabolic-dysfunction associated steatotic liver disease: A large, multicenter study.

Background & Aims: The available literature on the effect of apolipoprotein C-III (ApoC-III) inhibition in MASLD reveals inconsistencies. The aim of the present work was to examine levels of ApoC-III in the entire spectrum of metabolic-dysfunction associated steatotic liver disease (MASLD).

Methods: This is a multicenter study involving patients enrolled in two gastroenterology-hepatology clinics (Greece and Australia) and in a bariatric-metabolic surgery clinic (Italy), with liver biopsy before and after bariatric surgery or lifestyle modification.

The effect of lipid-lowering treatment on indices of MASLD in familial hypercholesterolemia patients.

Background & Aims: The effect of lipid-lowering treatment (LLT) on metabolic dysfunction associated steatotic liver disease (MASLD) is unclear. This is relevant for patients with familial hypercholesterolemia (FH) who are on lifelong LLT. We aimed to evaluate the effect of LLT on MASLD indices in this population.
