Genome-Wide Interaction Analysis with DASH Diet Score Identified Novel Loci for Systolic Blood Pressure.

OBJECTIVE: We examined interactions between genotype and a Dietary Approaches to Stop Hypertension (DASH) diet score in relation to systolic blood pressure (SBP). METHODS: We analyzed up to 9,420,585 biallelic imputed single nucleotide polymorphisms (SNPs) in up to 127,282 individuals of six population groups (91% of European population) from the Cohorts for Heart and Aging Research in Genomic Epidemiology consortium (CHARGE; n=35,660) and UK Biobank (n=91,622) and performed European population-specific and cross-population meta-analyses. RESULTS: We identified three loci in European-specific analyses and an additional four loci in cross-population analyses at P for interaction < 5e-8. We observed a consistent interaction between rs117878928 at 15q25.1 (minor allele frequency = 0.03) and the DASH diet score (P for interaction = 4e-8; P for heterogeneity = 0.35) in European population, where the interaction effect size was 0.42±0.09 mm Hg (P for interaction = 9.4e-7) and 0.20±0.06 mm Hg (P for interaction = 0.001) in CHARGE and the UK Biobank, respectively. The 1 Mb region surrounding rs117878928 was enriched with cis-expression quantitative trait loci (eQTL) variants (P = 4e-273) and cis-DNA methylation quantitative trait loci (mQTL) variants (P = 1e-300). While the closest gene for rs117878928 is MTHFS, the highest narrow sense heritability accounted by SNPs potentially interacting with the DASH diet score in this locus was for gene ST20 at 15q25.1. CONCLUSION: We demonstrated gene-DASH diet score interaction effects on SBP in several loci. Studies with larger diverse populations are needed to validate our findings

Sugar-Sweetened Beverage Consumption May Modify Associations Between Genetic Variants in the CHREBP (Carbohydrate Responsive Element Binding Protein) Locus and HDL-C (High-Density Lipoprotein Cholesterol) and Triglyceride Concentrations

Background:ChREBP (carbohydrate responsive element binding protein) is a transcription factor that responds to sugar consumption. Sugar-sweetened beverage (SSB) consumption and genetic variants in the CHREBP locus have separately been linked to HDL-C (high-density lipoprotein cholesterol) and triglyceride concentrations. We hypothesized that SSB consumption would modify the association between genetic variants in the CHREBP locus and dyslipidemia.Methods:Data from 11 cohorts from the Cohorts for Heart and Aging Research in Genomic Epidemiology consortium (N=63 599) and the UK Biobank (N=59 220) were used to quantify associations of SSB consumption, genetic variants, and their interaction on HDL-C and triglyceride concentrations using linear regression models. A total of 1606 single nucleotide polymorphisms within or near CHREBP were considered. SSB consumption was estimated from validated questionnaires, and participants were grouped by their estimated intake.Results:In a meta-analysis, rs71556729 was significantly associated with higher HDL-C concentrations only among the highest SSB consumers (β, 2.12 [95% CI, 1.16–3.07] mg/dL per allele; PConclusions:Our results identified genetic variants in the CHREBP locus that may protect against SSB-associated reductions in HDL-C and other variants that may exacerbate SSB-associated increases in triglyceride concentrations.Registration:URL: https://www.clinicaltrials.gov; Unique identifier: NCT00005133, NCT00005121, NCT00005487, and NCT00000479.</p

Similar results were observed for 2 additional variants (rs35709627 and rs71556736). For triglyceride, rs55673514 was positively associated with triglyceride concentrations only among the highest SSB consumers (beta, 0.06 [95% CI, 0.02-0.09] In-mg/dL per allele, P=0.001) but not the lowest SSB consumers (P=0.84; P-Diff=0.0005).CONCLUSIONS: Our results identified genetic variants in the CHREBP locus that may protect against SSB-associated reductions in HDL-C and other variants that may exacerbate SSB-associated increases in triglyceride concentrations.Clinical epidemiolog

Implementación de una herramienta de seguridad alimentaria en empresas de Zacatecas

This work aims to be a base document for companies to participate in international markets, through the implementation of the food safety tool of the Hazard Analysis and Critical Control Points (HACCP) system. Therefore, it was necessary to develop a new instrument for the collection of information, in which five dimensions were considered: (D1) Profitability, (D2) Safety, (D3) Competitiveness, (D4) Clients and (D5) Human resources. This study is quantitative and descriptive transsectional and was carried out in all the companies of the state of Zacatecas in the agri-food sector (meat) with the HACCP system in operation and certified. The most relevant, identified benefits found are the following: (1) The Zacatecan companies in the agri-food sector can meet international criteria and export to a highly competitive market, with the market of the United States of North America being of high interest. This reason is that it is a country that is considered to have a significant commercial presence. (2) These companies implemented the HACCP system due to legal requirements. (3) The profitability of implementing the HACCP system was identified, being adequate in terms of cost-benefit. However, there is no reduction in operating or administrative costs. In this work, two specific objectives were proposed: (1) Identify the characteristics that micro and medium-sized companies from other states in México must achieve to implement a food safety tool. So that in the medium term they can participate in international markets and consequently increase their economic dividends; and (2) Determine the cost-benefit of having implemented the HACCP system in Zacatecan companies in the agri-food sector (meat).Este trabajo pretende ser un documento base para que las empresas participen en los mercados internacionales, mediante la implementación de la herramienta de seguridad alimentaria del sistema de Análisis de Peligros y Puntos Críticos de Control (HACCP). Por lo tanto, fue necesario desarrollar un nuevo instrumento para la recolección de información, en el cual se contemplaron cinco dimensiones: (D1) Rentabilidad, (D2) Seguridad, (D3) Competitividad, (D4) Clientes y (D5) Recursos humanos. Este estudio es transeccional cuantitativo y descriptivo y se realizó en todas las empresas del estado de Zacatecas, México del sector agroalimentario (cárnicos) con el sistema HACCP en funcionamiento y certificado. Los beneficios identificados más relevantes encontrados son los siguientes: (1) Las empresas zacatecanas del sector agroalimentario pueden cumplir con criterios internacionales y exportar a un mercado altamente competitivo, siendo de alto interés el mercado de los Estados Unidos de Norteamérica. Esta razón es que es un país que se considera que tiene una presencia comercial significativa. (2) Estas empresas implementaron el sistema HACCP debido a requisitos legales. (3) Se identificó la rentabilidad de implementar el sistema HACCP, siendo adecuada en términos de costo-beneficio. Sin embargo, no hay reducción de costos operativos o administrativos. En este trabajo se propusieron dos objetivos específicos: (1) Identificar las características que deben alcanzar las micro y medianas empresas de otros estados para implementar una herramienta de seguridad alimentaria. Para que en el mediano plazo puedan participar en los mercados internacionales y consecuentemente incrementar sus dividendos económicos; y (2) determinar el costo-beneficio de haber implementado el sistema HACCP en empresas zacatecanas del sector agroalimentario (cárnicos)

We hypothesized that SSB consumption would modify the association between genetic variants in the CHREBP locus and dyslipidemia. METHODS: Data from 11 cohorts from the Cohorts for Heart and Aging Research in Genomic Epidemiology consortium (N=63 599) and the UK Biobank (N=59 220) were used to quantify associations of SSB consumption, genetic variants, and their interaction on HDL-C and triglyceride concentrations using linear regression models. A total of 1606 single nucleotide polymorphisms within or near CHREBP were considered. SSB consumption was estimated from validated questionnaires, and participants were grouped by their estimated intake. RESULTS: In a meta-analysis, rs71556729 was significantly associated with higher HDL-C concentrations only among the highest SSB consumers (β, 2.12 [95% CI, 1.16-3.07] mg/dL per allele; P<0.0001), but not significantly among the lowest SSB consumers (P=0.81; PDiff <0.0001). Similar results were observed for 2 additional variants (rs35709627 and rs71556736). For triglyceride, rs55673514 was positively associated with triglyceride concentrations only among the highest SSB consumers (β, 0.06 [95% CI, 0.02-0.09] ln-mg/dL per allele, P=0.001) but not the lowest SSB consumers (P=0.84; PDiff=0.0005). CONCLUSIONS: Our results identified genetic variants in the CHREBP locus that may protect against SSB-associated reductions in HDL-C and other variants that may exacerbate SSB-associated increases in triglyceride concentrations.
