Background: Insulin resistance (IR) in adults has been associated with intrauterine growth restriction (IUGR). Leptin and adiponectin correlations with anthropometric parameters and IR at 72 h in discordant twins were tested.
Methods: We included 24 discordant (birth weight discordance ≥20% in relation to the heavier cotwin) and 30 concordant (birth weight discordance ≤10%) twins.
Results: A correlation between leptin (but not adiponectin) level and birth weight (BW), birth length and head circumference in IUGR twins was recorded (p<0.05). Insulin sensitivity (IS) and homeostatic model assessment (HOMA)-IR in IUGR twins were similar to appropriate-for-gestational-age cotwins and unrelated to adipokines. In IUGR twins, adiponectin and insulin associated positively. In larger concordant twins' leptin level correlated with HOMA-IR and insulin.
Conclusions: Leptin, but not adiponectin, levels correlate positively with anthropometric parameters in IUGR twins. IR in IUGR twins is unrelated to adipokines in the first few days of life.

This meta-analysis aims to compile all randomised controlled trials (RCTs) that examined the effects of grapes or grape products on adult anthropometric measures and serum adipokines. We searched PubMed, Scopus, Google scholar, Web of Science and CENTRAL databases published before January 2022. Random-effects model was used to combine mean differences between intervention and placebo groups.

Contrary to the evidence supporting the role for insulin in stimulating uterine contraction, only a limited number of studies have highlighted the inhibitory effect of insulin on myometrial contractions in human and rodent. A hypothetical narrative review of the current literature was conducted, revealing the current literature and shows the potential inhibitory effects of insulin on myometrial contractility. These inhibitory mechanisms include activation of adenylyl cyclase signaling pathways, an increase in cAMP production, a decrease in Ca influx and cytosolic Ca, hyperpolarization of the cell membrane, and stimulation of NO synthesis.

The chronotype, the personal predisposition towards morning or evening activities, significantly influences health conditions, sleep, and eating regulations. Individuals with evening chronotypes are often at a higher risk for weight gain due to misalignment between their natural tendencies of functioning and social schedules, resulting in insufficient sleep, disruptions in eating habits, and decreased physical activity levels. Often, impaired glucose tolerance and changes in melatonin, adiponectin, and leptin secretion, along with alterations in the clock gene functions in subjects with evening preferences, may be predisposed to obesity.

Maximal physical effort induces a disturbance in the body's energy homeostasis and causes oxidative stress. The aim of the study was to determine whether prooxidant-antioxidant balance disturbances and the secretion of adipokines regulating metabolism, induced by maximal intensity exercise, are dependent on body composition in young, healthy, non-obese individuals. We determined changes in the concentration of advanced protein oxidation products (AOPP), markers of oxidative damage to nucleic acids (DNA/RNA/ox), and lipid peroxidation (LPO); catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx) activity, as well as concentrations of visfatin, leptin, resistin, adiponectin, asprosin, and irisin in the blood before and after maximal intensity exercise in men with above-average muscle mass (NFAT-HLBM), above-average fat mass (HFAT-NLBM), and with average body composition (NFAT-NLBM).

To examine the changes in obesity-related hormones and metabolic syndrome markers in male high school students with obesity following a weekend-focused moderate- or high-intensity exercise program at the recommended weekly physical activity level, or a program of regular exercise 3 times a week at moderate intensity, over a 10-week period. Forty-eight male high school students who were obese with a body fat percentage of ≥25% were randomly assigned to one of three groups: a regular moderate-intensity exercise group (n=17) that freely selected and performed moderate-intensity aerobic and resistance training exercises, every Monday, Wednesday, and Friday, for a total of 150-300 min/wk; a weekend-focused moderate-intensity exercise group (n=15) that freely selected and performed aerobic and resistance training exercises every Saturday for 150-300 min; and a week-end-focused high-intensity exercise group (n=16) that freely selected and performed aerobic and resistance training exercises every Sunday for 75-150 min. Insulin and leptin levels significantly decreased in all the groups, with the greatest reduction in the regular exercise group.
