Article Abstract
Background: Apoptosis antigen 1/FAS receptor (APO1/Fas) signaling in endothelial cells plays a significant role in angiogenesis while increased mean platelet volume (MPV) is an important marker for platelet activation. We investigated the possible correlation between APO1/Fas and both metabolic parameters and platelet activity (indicated by the MPV) in a healthy pediatric population.
Methods: One hundred and eighty-five children, aged 5-17 years old, were enrolled in the study. The participants were divided into subgroups according to their age and body mass index percentile (BMI%). APO1/Fas was measured by enzyme-linked immunosorbent assay (ELISA) and MPV by the MEK-6410K.
Results: Eighty-one children (43.8%) had excess weight, which was more prevalent in children ≤9 years of age. Sixty-five children (35.1%) exhibited a predisposition for metabolic syndrome. A negative correlation was found between APO1/Fas and predisposing factors for metabolic syndrome: Glucose, cholesterol, uric acid, low-density lipoprotein (LDL), and triglycerides. In contrast, a positive correlation was found between APO1/Fas and C-reactive protein (CRP). Receiver operating characteristic (ROC) analysis showed a predisposition to metabolic syndrome when APO1/Fas was <78.46 pg/mL. A negative correlation was also observed between APO1/Fas and MPV. MPV was also positively correlated with predisposing factors for metabolic syndrome: BMI%, glucose, cholesterol, uric acid, LDL, and negatively with high-density lipoprotein.
Conclusions: APO1/Fas expression is associated with a lower predisposition to metabolic syndrome may be through endothelial homeostasis, the induction of apoptosis of cells involved in atherosclerosis, and platelet activity. It may also enhance CRP-mediated noninflammatory clearance of apoptotic cells. Early monitoring of all the components of metabolic syndrome in overweight children is important in order to prevent metabolic and cardiovascular complications.

The emerging role of Nrf2 in heart failure: From cardioprotection to therapeutic approaches.
ESC Heart Fail
September 2025
Department of Clinical and Molecular Medicine, Sapienza University, Rome, Italy.
Heart failure (HF) is a multifactorial and pathophysiological complex syndrome, involving not only neurohormonal activation but also oxidative stress, chronic low-grade inflammation, and metabolic derangements. Central to the cellular defence against oxidative damage is nuclear factor erythroid 2-related factor 2 (Nrf2), a transcription factor that orchestrates antioxidant and cytoprotective responses. Preclinical in vitro and in vivo studies reveal that Nrf2 signalling is consistently impaired in HF, contributing to the progression of myocardial dysfunction.

Background: This study aimed to investigate the association between adiponectin levels and the incidence of metabolic dysfunction- associated steatotic liver disease (MASLD) and nonalcoholic fatty liver disease (NAFLD), and to explore the predictive value of adiponectin in the onset of these conditions.
Methods: A 17-year follow-up of 35,026 individuals from the Korean Cancer Prevention Study-II biobank cohort (2004-2021) was conducted. Adiponectin levels were categorized into quintiles.

Background: The gut microbiota plays a vital role in various physiological processes, including metabolism. Fecal microbiota transplantation (FMT) involves transferring fecal matter from a healthy donor to rebalance a patient's intestinal dysbiosis. The impact of FMT on metabolic syndrome (MetS) is subject to debate.

Indigenous Australians have long recognised and utilised the therapeutic potential of Australian native plants for generations to treat and manage various diseases. In recent years, these native plants have been explored in preclinical research for their chemical profiles and therapeutic properties for conditions such as skin disorders, colds and flu, various cancers, neurological disorders, metabolic syndrome, and other inflammatory conditions. Notable species studied include Kakadu plum, Davidson's plum, Burdekin plum, Illawarra plum, anise myrtle, lemon myrtle, lemon aspen, quandong, muntries, and Tasmanian pepperberry.

Purpose: Although insulin resistance (IR) varies with age and puberty in children and adolescents, most previous attempts to determine cutoff values for IR indices overlook factor. This study assesses age-related differences in IR index values and evaluates how diagnostic performance varies by age when using a uniform cutoff for diagnosing metabolic syndrome (MetS) without considering age.
Methods: We analyzed age-related differences in IR indices (the homeostatic model assessment of insulin resistance [HOMA-IR], triglyceride-glucose [TyG] index, and triglyceride/high-density lipoprotein cholesterol [TG/HDL-C] ratio) among 1,641 participants in the 2019-2021 Korea National Health and Nutrition Examination Survey.
