Background: In obesity, elevated insulin resistance is observed, which may be associated with disturbances in mineral status in the body. The few studies concerning the status of minerals and their relationships with insulin resistance and body composition in adolescent populations have brought inconclusive results.
Aim: of this study is, thus, to assess serum mineral concentration in obese adolescents, and to evaluate their potential association with insulin resistance.
Subjects And Methods: Seventy-eight obese adolescents and 20 healthy volunteers aged 12-18 years were recruited for the study. Selected anthropometrical measurements and levels of iron, zinc, copper, calcium, and magnesium were assessed in serum. Insulin resistance in the participants was evaluated according to the homeostatic model of assessment for insulin resistance (HOMA-IR) protocol. Levels of iron, zinc, copper, calcium, and magnesium were assessed in serum.
Results: Obese subjects had significantly higher HOMA-IR indices than the control group. Compared to healthy subjects, the serum concentration of zinc, calcium, and magnesium was significantly lower in obese subjects. A significant inverse relation was found between HOMA-IR and zinc levels in serum.
Conclusions: Obese adolescents have a poorer mineral status (especially zinc) than adolescents of normal weight, which can contribute to insulin resistance.

Purpose Of Review: Metabolic dysfunction associated steatotic liver disease (MASLD) is increasing throughout the world, affecting nearly one in three individuals. Kidney stone disease, which is also increasing, is associated with MASLD. Common risk factors for both, including obesity, diabetes, dyslipidemia, hypertension, and metabolic syndrome, are likely drivers of this association.

Growing evidence indicates that type 2 diabetes (T2D) is associated with an increased risk of developing Parkinson's disease (PD) through shared disease mechanisms. Studies show that insulin resistance, which is the driving pathophysiological mechanism of T2D plays a major role in neurodegeneration by impairing neuronal functionality, metabolism and survival. To investigate insulin resistance caused pathological changes in the human midbrain, which could predispose a healthy midbrain to PD development, we exposed iPSC-derived human midbrain organoids from healthy individuals to either high insulin concentration, promoting insulin resistance, or to more physiological insulin concentration restoring insulin signalling function.

Background: Liver cirrhosis is considered a progressive disease that can eventually result in death. Vitamin D deficiency is prevalent in patients with cirrhosis. Few studies have been conducted on the effect of vitamin D supplementation in patients with cirrhosis.

Background: Insulin resistance is tightly related to cognition; however, the causal association between them remains a matter of debate. Our investigation aims to establish the causal relationship and direction between insulin resistance and cognition, while also quantifying the mediating role of brain cortical structure in this association.
Methods: The publicly available data sources for insulin resistance (fasting insulin, homeostasis model assessment beta-cell function and homeostasis model assessment insulin resistance, proinsulin), brain cortical structure, and cognitive phenotypes (visual memory, reaction time) were obtained from the MAGIC, ENIGMA, and UK Biobank datasets, respectively.

Background: Activities in daily living (ADLs) disability triggered by aging population and chronic diseases in the middle-aged and older adults has become a major public health challenge. Cardiovascular-kidney-metabolic (CKM) syndrome, as a combination of several chronic conditions, has not yet been studied to explore its association with ADLs disability. We examined the association between CKM syndrome and ADLs disability among middle-aged and older adults in China and whether it varied by age and socioeconomic status.
