Metabolic syndrome (MetS) is a combination of metabolic disorders associated with an increased risk for cardiovascular disease (CVD). Studies in women reported associations between polymorphisms in ESR1, LPL and CETP genes and MetS. Our aim was to evaluate the association between variants in ESR1, LPL and CETP genes with MetS and its components. Four hundred and eighty women were analyzed, anthropometric features and biochemical profiles were evaluated, and genotyping was performed by real-time PCR. We found an association with elevated glucose levels (odds ratio (OR) = 2.9; p = 0.013) in carrying the AA genotype of rs1884051 in the ESR1 gene compared with the GG genotype, and the CC genotype of rs328 in the LPL gene was associated with MetS compared to the CG or GG genotype (OR = 2.8; p = 0.04). Moreover, the GA genotype of rs708272 in the CETP gene is associated with MetS compared to the GG or AA genotype (OR = 1.8; p = 0.006). In addition the ACTCCG haplotype in the ESR1 gene is associated with a decrease in the risk of MetS (OR = 0.02; p < 0.001). In conclusion, our results show the involvement of the variants of ESR1, LPL and CETP genes in metabolic events related to MetS or some of its features.

Traditionally, research on addictive behaviors has been based on the study of their risk factors, with impulsivity being the main risk factor. However, this study aims to approach this topic from the analysis of decision making. According to the prospect theory, low levels of loss and risk aversion will increase the probability of showing addictive behaviors. A systematic review of the possible relationships between these behaviors and prospect theory was carried out. To this end, the works that have studied loss and risk aversion in populations with addictive behaviors to date (N = 15) were compiled. Apart from other eligibility criteria, the selection process was only performed with studies that included the prospect theory or cumulative prospect theory, in English or Spanish, since 1979. WoS, Scopus, Dialnet and PsycInfo were the information sources selected. For this purpose, PRISMA guidelines have been followed. It was found that users of addictive substances show less loss aversion than nonusers. These results cannot be transferred to pathological gamblers. The significance of this work for future research and the implementation of prevention and intervention programs is highlighted. The results show an approach to addictions from a novel perspective.

Apolipoprotein E (ApoE) 4 isoform has been associated with elevated levels of cholesterol, low-density lipoprotein cholesterol (LDL-C), and triglycerides (TGs), meanwhile several polymorphisms in the LDL receptor (LDLR) gene have been associated with increased levels of total cholesterol and LDL-C. We studied 400 women from Southwest Mexico. Anthropometric features and biochemical profile were evaluated, and genotyping of single nucleotide polymorphisms rs429358 and rs7412 in the APOE gene and rs688 in the LDLR gene was determined by TaqMan assays. We found significant association between LDL-C (odds ratio [OR] = 3.3, 95% confidence interval [CI]: 1.9-5.7) and marginal association with TG (OR = 1.7, 95% CI: 1.0-2.9) of atherogenic risk in women carriers of the ApoE4 isoform compared to ApoE3. The TT genotype of rs688 in the LDLR gene was not found to be associated with elevated levels of total cholesterol or LDL-C. Our results show that carrier women of the ApoE4 isoform are more likely to have elevated levels of LDL-C and therefore increased risk of developing atherosclerosis.

Objective: Mexico's current population structure has been defined by admixture between European, Native American, and to some extent African, groups that started in the sixteenth century. The aim of this research was to analyze the relative contributions of these continental population groups to the seven regions of the state of Guerrero, Mexico.Methods: A total of 104 ancestry informative markers were analyzed in 480 unrelated women from the seven regions of the state of Guerrero. The individual ancestry proportions were estimated using the software ADMIXMAP v3.2.Results: The relative Native American, European and African ancestral contributions to the whole sample were estimated to be 69%, 27%, and 1.9%, respectively. We observed significant differences in admixture proportions across the regions. The highest average Native American ancestry was found in the Montaña region and the lowest in Costa Grande. Conversely, the highest European contribution was observed in Costa Grande. The highest African contributions were observed in the regions of Costa Chica and Costa Grande.Conclusions: The genetic structure of the population of Guerrero reflects quite well the historical processes that have occurred in this state. Native American population settlements were mainly in the regions of Montaña, Norte, and Centro, where the highest indigenous genetic contribution is observed today. European settlers came from the center of the state to regions with significant agricultural and mining activities. The highest African contributions are observed in coastal regions, in agreement with historical evidence about slave trade routes in the Americas.

Insulin resistance (IR) is a key contributor to the development of metabolic diseases, and metformin has been shown to help mitigate IR. Long non-coding RNAs (lncRNAs) are emerging as important regulators in metabolic disorders. This study aimed to investigate the differential expression of lncRNAs in IR and assess the impact of metformin on these lncRNAs. Using the Huh7 cell line to model IR (Huh7-IR), we treated the cells with metformin (Huh7-IR+Metf). Microarray analysis, followed by bioinformatic analysis in RStudio, identified 127 downregulated and 109 upregulated lncRNAs, among which 60 showed reduced expression following metformin treatment in Huh7-IR cells. Notably, the upregulated lncRNAs HOX transcript antisense RNA (HOTAIR), long intergenic non-protein coding RNA, muscle differentiation 1 (LINCMD1) and Prader-Willi region non-protein coding RNA 2 (PWRN2) were found to be associated with genes involved in the insulin signaling pathway. These three lncRNAs were further validated using real-time RT-PCR. This study highlights the differential expression of lncRNAs in IR and their modulation by metformin. Specifically, metformin restores the expression of lncRNAs that were deregulated in IR, including HOTAIR, LINCMD1, and PWRN2, likely through the regulation of critical biological processes and signaling pathways associated with IR. In conclusion, our findings demonstrate that metformin modulates the expression of key lncRNAs, including HOTAIR, LINCMD1, and PWRN2, which are deregulated in insulin resistance. This regulation likely occurs through the modulation of critical signaling pathways, such as NFκB and AMPK, suggesting that targeting lncRNAs could offer new therapeutic avenues for managing IR and related metabolic disorders.

El sobrepeso y obesidad son un problema de salud pública, aumentan la prevalencia de enfermedades crónicas degenerativas. Para evaluar la efectividad de una intervención educativa (IE) de sobrepeso y obesidad, se realizó un estudio cuasi-experimental en escolares. El análisis se realizó en STATA v.16.0, las variables cualitativas se expresan en frecuencias y McNemar; p<0.05 fue significativo. En la antropometría participaron 113 escolares, el índice de masa corporal (IMC), reportó 51.3% bajo peso, 7.1% sobrepeso y 5.3% obesidad, la presión arterial se encontró baja y elevada en 1.8%, respectivamente. En la IE participaron 117 infantes (50.4% niñas); en la autopercepción corporal, las niñas se percibieron con bajo peso (antes, 45.2% vs después, 45.2%) y sobrepeso (1% vs 1%); los niños con bajo peso (41% vs 36.7%), sobrepeso (6% vs 6.7%) y obesidad (0% vs 1%). Aumentó el conocimiento de sobrepeso (30.8% vs 75.2%) y obesidad (17.1 vs 72.6%); sus causas (comida chatarra [40. 2% vs 45.1%] y comidas rápidas [36.3% vs 44.1%]). Consideran la hiperglucemia (66.7% vs 89.7%) e hipertensión (47% vs 83.8%) como principales consecuencias. La mitad de los escolares presentaron bajo peso y doce de cien sobrepeso u obesidad, se modificó el conocimiento del sobrepeso, obesidad, causas y consecuencias.
