Aim: The aim of this study was to examine whether there is an association of insulin sensitivity with periodontal infection in a non-diabetic, non-smoking adult population.

Materials And Methods: A subpopulation of the Health 2000 Survey (effective n=2050) consisted of dentate subjects without any indication of diabetes, aged between 30 and 64, and who had never smoked. The outcome variable was periodontal infection measured by means of the number of teeth with deepened periodontal pockets. Insulin sensitivity was measured using the homeostasis model assessment index for insulin resistance. Poisson regression models were used to estimate the relative risks and 95% confidence intervals.

Results: We found that insulin sensitivity was associated with periodontal infection in the age group 30-49, but not in persons aged 50-64. Controlling for body weight made the association between insulin sensitivity and periodontal infection disappear.

Conclusion: The lack of knowledge of the underlying causal model prevents making definite conclusions about the role of reduced insulin sensitivity in the pathogenesis of periodontal infection.

Arsenic exposure can induce liver insulin resistance (IR) and diabetes (DM), but the underlying mechanisms are not yet clear. Circular RNAs (circRNAs) are involved in the regulation of the onset of diabetes, especially in the progression of IR. This study aimed to investigate the role of circRNAs in arsenic-induced hepatic IR and its underlying mechanism.

: The prevalence of metabolic syndrome in children has been increasing, raising concerns about early detection and clinical management. Adipokines, which are secreted by adipose tissue, play a critical role in metabolic regulation and inflammation, while gamma-glutamyl transferase (GGT), as a liver enzyme, is linked to oxidative stress and metabolic disorders. The objective was to examine the association of circulating adipokines and GGT with metabolic syndrome risk in school-aged children from Northeast Mexico.

Background: Anabolic resistance accelerates muscle loss in aging and obesity, thus predisposing to sarcopenic obesity.

Methods: In this retrospective analysis of a randomized clinical trial, we examined baseline predictors of the adaptive response to three months of home-based resistance exercise, daily physical activity, and protein-based, multi-ingredient supplementation (MIS) in a cohort of free-living, older males ( = 32).

Results: Multiple linear regression analyses revealed that obesity and a Global Risk Index for metabolic syndrome (MetS) were the strongest predictors of Δ% gains in lean mass (TLM and ASM), LM/body fat ratios (TLM/%BF, ASM/FM, and ASM/%BF), and allometric LM (ASMI, TLM/BW, TLM/BMI, ASM/BW), with moderately strong, negative correlations to the adaptive response to polytherapy r = -0.

: It is unknown whether the negative health effects associated with ultra-processed foods (UPFs) are due to their nutritional composition or to the extent of food processing itself. We evaluated the impact of a test meal composed only of UPF, according to the NOVA classification, compared to a similar meal without UPF in adults with obesity. : This is a parallel, randomized trial.

: The ketogenic diet (KD) is a dietary model that can impact metabolic health and microbiota and has been widely discussed in recent years. This study aimed to evaluate the effects of a 6-week KD on biochemical parameters, gut microbiota, and fecal short-chain fatty acids (SCFAs) in women with overweight/obesity. : Overall, 15 women aged 26-46 years were included in this study.
