Gene-Diet Interactions in Colorectal Cancer: Survey Design, Instruments, Participants and Descriptive Data of a Case-Control Study in the Basque Country.

Epidemiologic studies have revealed inconsistent evidence of gene-diet interaction in relation to colorectal cancer (CRC). The aim of this study was to analyze them in a sample of cases and controls from the population-based bowel cancer screening program of the Osakidetza/Basque Health Service. This study analyzed dietetic, genetic, demographic, socioeconomic factors and lifestyles.

Validation of a 52-mtSNP minisequencing panel for haplogroup classification of forensic DNA samples.

Mitochondrial DNA (mtDNA) is a useful tool in forensic investigation as it provides information about the matrilineal ancestry of individuals. In addition, mtDNA can be analyzed when the analysis of other nuclear markers is underperforming. Recently, we developed a minisequencing panel for the simultaneous analysis of 52 mtDNA SNPs to classify maternal lineages into the main haplogroups and their phylogeographic origin.

Single nucleotide polymorphisms associated with susceptibility for development of colorectal cancer: Case-control study in a Basque population.

Given the significant population diversity in genetic variation, we aimed to investigate whether single nucleotide polymorphisms (SNPs) previously identified in studies of colorectal cancer (CRC) susceptibility were also relevant to the population of the Basque Country (North of Spain). We genotyped 230 CRC cases and 230 healthy controls for 48 previously reported CRC-susceptibility SNPs. Only the rs6687758 in DUPS10 exhibited a statistically significant association with CRC risk based on the crude analysis.

Effective resolution of the Y chromosome sublineages of the Iberian haplogroup R1b-DF27 with forensic purposes.

Single-nucleotide polymorphisms (SNPs) found within the non-recombining region of the Y chromosome (NRY) represent a powerful tool in forensic genetics for inferring the paternal ancestry of a vestige and complement the determination of biogeographical origin in combination with other markers like AIMs. In the present study, we introduce a panel of 15 Y-SNPs for a fine-resolution subtyping of the haplogroup R1b-DF27, in a single minisequencing reaction. This is the first minisequencing panel that allows a fine subtyping of R1b-DF27, which displays high frequencies in Iberian and Iberian-influenced populations.

Development of a new screening method to determine the main 52 mitochondrial haplogroups through a single minisequencing reaction.

This work presents the design, development and optimization of a screening method based on single-base extension sequencing to simultaneously analyze a panel of 52 mitochondrial SNPs. This enables to recognize the main mitochondrial haplogroups and to discriminate even between lineages from the same phylogenetic branch that diverged in different continents. The unavailability of individuals harboring infrequent variants was a limitation to optimize the panel.

Nutritional Adequacy and Diet Quality in Colorectal Cancer Patients Postsurgery: A Pilot Study.

Recent evidence has shown that an unhealthy diet is associated with a higher risk of tumor recurrence, metastasis, and death among patients with colorectal cancer (CRC). The aims of this study were to assess nutritional adequacy and diet quality in a group of CRC patients postsurgery and to identify possible associations between dietary and nutritional aspects and environmental factors and weight status. This was an observational study conducted on a random sample of 74 patients, aged 50-69 years.

Associations between STR autosomal markers and longevity.

Life span is a complex and multifactorial trait, which is shaped by genetic, epigenetic, environmental, and stochastic factors. The possibility that highly hypervariable short tandem repeats (STRs) associated with longevity has been largely explored by comparing the genotypic pools of long lived and younger individuals, but results so far have been contradictory. In view of these contradictory findings, the present study aims to investigate whether HUMTHO1 and HUMCSF1PO STRs, previously associated with longevity, exert a role as a modulator of life expectancy, as well as to assess the extent to which other autosomal STR markers are associated with human longevity in population from northern Spain.

[Relationship between the ratio of fish to meat consumption and diet adequacy in university young women].

Introduction: In Western populations fish consumption is lower than meat consumption and this fact can influence on the total diet quality.

Objective: Verify if the relationship between the ratio of fish to meat consumption and diet adequacy and quality in a group of women university students.

Participants And Methods: 47 women of the University of the Basque Country (UPV/EHU) took part in this study; the mean age was 19.

[Influence of sport practice and physical exercise on anthropometric indicators and weight satisfaction in men university students: a pilot study].

Introduction: University students generally have low levels of physical activity, which could affect the body weight and composition and the knowledge and acceptance of their own body.

Objective: To assess weight status and body composition, as well as self-perception and satisfaction with body weight in university students, and to analyze the influence of sport practice and physical exercise on these variables.

Methods: A sample of 62 male students with a mean age of 20.

Prevalence and magnitude of body weight and image dissatisfaction among women in dietetics majors.

Some authors have suggested that body weight dissatisfaction may be high in students majoring in dietetics. Therefore, this study was conducted to examine the extent of body weight and image dissatisfaction in a sample of women in dietetics major. Additionally, predictors of magnitude of body weight dissatisfaction were analyzed.

Cooperative learning strategies to teach nutrition to geriatric nursing staff.

The objective of this study was to test the hypothesis that cooperative learning strategies will help to increase nutrition knowledge of nurses and nursing assistants caring for the elderly in different institutional communities of the Basque Country, Spain. The target population was a sample of volunteers, 16 nurses and 28 nursing assistants. Training consisted of 12 nutrition education sessions using cooperative strategies conducted over a period of 3 consecutive weeks.

GSTT1 and GSTM1 gene copy number analysis in paraffin-embedded tissue using quantitative real-time PCR.

GSTT1 and GSTM1 genes possess an inherited deletion associated with a lack of enzyme activity. The heterozygous condition of this deletion is difficult to determine in low-quality DNA with existing PCR protocols. We designed and validated a multiplex real-time PCR assay by adapting the DeltaDeltaCt relative quantification method for the analysis of GSTT1 and GSTM1 markers to accurately differentiate the three genotypes ( *1/1, *1/0, and *0/0) in degraded DNA from formalin-fixed paraffin-embedded tissue.

Body shape in relation to socio-economic status in young adults from the basque Country.

Body shape has a great variability determined, partly, by energy intake and physical activity, as well as by gender and age. The aim of this research was to analyse the relation between socio-economic status (SES) and body shape estimated through the somatotype, in a sample of university students. The sample included 316 males and 635 females aged 18-33.

A short training program improves the accuracy of portion-size estimates in future dietitians.

[Anthropometric characterization of an institutionalized elderly population from Caracas, Venezuela].

Most of the anthropometric standards are derived from adult populations but not from older subjects, so their use to evaluate the nutritional status in the elderly may not be the most appropriate. In this sense, the anthropometric characteristics and their relationship to sex and age in a cross-sectional sample of 809 Venezuelan subjects (370 males and 439 females), aged 60 to 102 years old, randomly selected from a elderly institution-alised population were studied. The results indicate that anthropometric variables show different degrees and signs of sexual dimorphism.
