Clinical, anthropometric, and laboratory data were obtained from 237 adults. Genomic DNA was extracted and genetic variants were analyzed by real-time polymerase chain reaction. Food intake was assessed in 81 subjects with obesity, who underwent a 9-week nutritional orientation program. Multivariate logistic regression analysis adjusted by covariates showed association of <em>GHRL</em> rs26311-G and rs4684677-A alleles with risk of type 2 diabetes (T2D) and/or metabolic syndrome (<em>P</em> &lt; .05), and <em>RETN</em> rs7408174-C allele with risk of T2D and obesity (<em>P</em> &lt; .05). Covariate-adjusted multivariate linear regression analysis showed association of <em>PLIN1</em> rs894160-G allele with increased waist-to-hip ratio (<em>P</em> = .003). The nutritional orientation program reduced carbohydrate and total fat intake, in subjects with obesity (<em>P</em> &lt; .05). Analysis of basal data revealed associations of <em>PLIN1</em> rs894160-G with increased body mass index, <em>PLIN1</em> rs2289487-A with reduced intake of total fat, monosaturated fatty acids and cholesterol, and <em>RETN</em> rs3745367-A with increased intake of protein and saturated fatty acids (<em>P</em> &lt; .05). <em>GHRL</em> rs26311-G was associated with increased postprogram protein intake (<em>P</em> = .044).

We investigated associations between long-term exposure to air pollutants, smoking status, VDD, and their combination with hypercholesterolemia using data from the 2008-2014 Korea National Health and Nutrition Examination Survey (KNHANES). We used linked data from the KNHANES to the daily moving average of air-pollution data from 730 days before the examination date, using participants’ addresses in latitude and longitude coordinates. Results were analyzed using a survey logistic regression model for complex sample analyses. We included 28,134 adults with data on serum vitamin D, cholesterol concentrations, smoking status, and air pollutant concentrations. After adjusting for potential covariates, adults with exposure to high concentrations of air pollutants and ever smokers showed significantly higher risks of VDD (odds ratios [ORs], 1.70; 95 % confidence intervals [CIs], 1.44-2.00). In the group with high air-pollutant exposure, adults with low vitamin D status and ever smokers had significantly higher risks of hypercholesterolemia (ORs, 1.55; 95 % CIs, 1.09-2.19) than adults with high vitamin D status and never smokers. We found that high air-pollutant exposure, ever smokers, and VDD may increase hypercholesterolemia prevalence in Korean adults. Therefore, to reduce hypercholesterolemia risk, adults living in areas with high air-pollution exposure may need adequate vitamin D intake and to avoid smoking.</div></div>","PeriodicalId":19245,"journal":{"name":"Nutrition Research","volume":"134 ","pages":"Pages 1-12"},"PeriodicalIF":3.4,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142971744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the aim of this pilot study is to investigate the effects of a whole fruit-rich diet on glycemic control, ectopic fat, and cardiovascular risk factors in adults with T2D. In this pilot study, sixteen adults aged 20 to 70 years with insulin-independent T2D for ≤6 years will complete a 12-week controlled-feeding intervention while maintaining their weight. During the ramp-up phase (weeks 1-4), participants progressively consume more whole fruit.

The primary outcome is glycemic control, assessed hierarchically by whether participants achieve nondiabetic glucose concentrations without antihyperglycemic medications; the total dose of antihyperglycemic medications; mean glucose during a three-hour oral glucose tolerance test; and mean 24-hour glucose from continuous glucose monitoring. Secondary outcomes include intrahepatic lipid, pancreatic fat, blood pressure, heart rate, and serum lipids. We hypothesize that a fruit-rich diet will improve glycemic control, reduce the need for antihyperglycemic medications, decrease ectopic fat, and improve cardiovascular risk factors.

This review explores the emerging therapeutic potential of BMEVs, highlighting their capacity to modulate recipient cell functions, influence immune responses, and contribute to overall infant health. Preclinical evidence suggests that these vesicles can prevent and manage conditions such as necrotizing enterocolitis, allergies, and viral infections, which are common in early childhood. Furthermore, BMEVs offer promise as vehicles for targeted drug delivery, enhancing the efficacy of therapeutic interventions. Despite the growing body of evidence, challenges such as the need for standardized isolation methods, characterization techniques, and larger-scale clinical studies persist, hindering the translation of this research into clinical practice. This review addresses these challenges and discusses future directions, emphasizing the need for comprehensive mechanistic studies to fully realize the potential of BMEVs as novel therapeutic agents and biomarkers of health. Ultimately, these vesicles represent a promising frontier in maternal and child health, with potential applications extending far beyond traditional nutrition. By harnessing their unique properties, BMEVs could revolutionize infant care, offering new strategies for disease prevention and innovative therapeutic interventions that enhance infant health outcomes.</div></div>","PeriodicalId":19245,"journal":{"name":"Nutrition Research","volume":"135 ","pages":"Pages 42-51"},"PeriodicalIF":3.4,"publicationDate":"2025-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143372054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
