Polymorphisms of the WNT16 gene are associated with the heel ultrasound parameter in young adults.

SUMMARY: Bone mineral content is influenced by genetic factors. We investigated the role of WNT16 in bone properties determined using quantitative ultrasound (QUS) on young adults. Three WNT16 genetic markers (rs2908007, rs2908004, and rs2707466) were found to have a significant association with the broadband ultrasound attenuation (BUA) measurement, suggesting that WNT16 influences bone mass in young adults. INTRODUCTION: The aim of this study was to investigate whether genetic markers on the WNT16 gene are associated with bone mass, as assessed using QUS in a population of healthy young Spanish adults. METHODS: A cross-sectional study was conducted on 575 individuals (mean age 20.41 ± 2.69). Bone quality was assessed using BUA measurements (dB/MHz) on the right calcaneus. Six single nucleotide polymorphisms (SNPs) (rs2908007, rs2908004, rs3801387, rs3801385, rs2707466, and rs2536184) covering the WNT16 gene were selected as genetic markers and genotyped to test their association with BUA variations. RESULTS: The rs2908007, rs2908004, and rs2707466 SNPs were found to have a significant association with BUA (p = 0.004, p = 0.001, and p = 0.004, respectively). CONCLUSION: We demonstrate for the first time that WNT16 genetic polymorphisms influence QUS traits in a population of young adults. This finding suggests that WNT16 might be an important genetic factor in determining peak bone mass acquisition.

Suffering indicators in terminally ill children from the parental perspective.

PURPOSE: Suffering is a complex multifaceted phenomenon, which has received limited attention in relation to children with terminal illness. As part of a wider study we interviewed parents of children with terminal illness to elicit their perspectives on suffering, in order to provide initial understanding from which to develop observational indicators and further research. METHODS: Qualitative descriptive study with semi-structured interviews made "ad hoc". Selection through deliberate sampling of mothers and fathers of hospitalised children (0-16 years old) with a terminal illness in Granada (Spain). KEY RESULTS: 13 parents were interviewed. They described children's suffering as manifested through sadness, apathy, and anger towards their parents and the professionals. The isolation from their natural environment, the uncertainty towards the future, and the anticipation of pain caused suffering in children. The pain is experienced as an assault that their parents allow to occur. CONCLUSIONS: The analysis of the interview with the parents about their perception of their ill children's suffering at the end of their lives is a valuable source of information to consider supportive interventions for children and parents in health care settings. An outline summary of the assessed aspects of suffering, the indicators and aspects for health professional consideration is proposed.

[Regulation of dietary intake and energy balance: factors and mechanisms involved]. / Regulación de la ingesta alimentaria y del balance energético: factores y mecanismos implicados.

UNLABELLED: The regulation of energy intake is a vital process in the body as possible to maintain a balance between the amount of energy stored as body fat and the catabolism of the same. OBJECTIVE: The objective of this study was to analyze the main factors involved in regulating food intake, energy balance and pathophysiology. METHODS: We searched Medline and Ebsco of articles published in English and Spanish in the period between January 2009 and January 2012. Search terms were "food intake", "energy balance", "regulation", "nutritional homeostasis." RESULTS: There were a total of 198 scientific studies, of which only 70 met the requirements of the search. All studies consulted agree on the importance of gastrointestinal hormones modulating agents as primary energy homeostasis. Such a modulatory effect on appetite and satiety is mediated by direct action on the hypothalamus or the nucleus of the solitary tract at the brainstem (autonomic nervous system). Only ghrelin has been linked to the start of the intake considering a major orexigenicas signals studied in animal models and humans. DISCUSSION: The regulation of food intake and energy balance is an extremely complex process whose operation and balance is made possible by the action of various endocrine signals of the gastrointestinal tract.

[Analysis of the nutritional state of school children in different districts of the province of Granada (Spain)]. / Análisis del estado nutricional en escolares; estudio por áreas geográficas de la provincia de Granada (España).

BACKGROUND: In Spain the prevalence of obesity shows a north-south distribution. In the province of Granada its distribution is unknown. OBJECTIVES: (1) To study the prevalence of overweight and obesity in a sample population of school children and adolescents from different districts in the province of Granada. (2) To verify whether there are significant differences, depending on the district where the students reside. (3) To find a possible correlation between the nutritional state of the students and that of their parents. METHODS: The population sample was composed of 977 school children and adolescents from 9 to 17 years of age, attending 13 public elementary schools and high schools in the city and province of Granada (Spain). In this analytical and multicentric study, the nutritional state of the subjects was evaluated by means of anthropometric measurements. Furthermore, data were collected by means of questionnaire to discover whether the respondents had a family history of overweight or obesity. RESULTS: We found a high prevalence of overweight and obesity among the studied population. In girls, the greater prevalence of both overweight and obesity ranged from 12 to 14 years of age. In boys, there was an increase in the prevalence of overweight at twelve years of age. Regarding obesity, their rates were significantly lower than those described among girls. There were statistically significant differences for weight (F = 4,154; p = 0,003) but not for height (F = 1,928; p =0,105). But for the variable BMI was statistically significant difference (F = 5.037; P < 0.001) between the studied geographical areas. The results showed that the nutritional state of students with a family history of obesity was significantly worse (p < 0.01). DISCUSSION: A high prevalence of obesity was found in the sample, especially among the girls. There exists a geographical distribution pattern, possibly derived from the socioeconomic characteristics of each area in the province. The existence of a family history of obesity is an important factor that can determine whether the child will also become obese in the future.

[Analysis of the nutritional state and body composition of school children in Granada (Spain)]. / Análisis del estado nutricional y composición corporal de una población de escolares de Granada.

The objective of this study was to first determine the nutritional state of a sample population of school children, and then analyze the distribution pattern of their subcutaneous fat layer. The sample was composed of 977 school children from the city and province of Granada (Spain). All of the children (524 girls and 452 boys) were 9-17 years of age. To study their nutritional state and the distribution of the subcutaneous fat layer, they were given a complete anthropometric evaluation, which included measuring their weight, height, body mass index, skin folds, and body perimeters. The results obtained showed a 23.01% prevalence of overweight in the female subjects and 20.81% in the male subjects. Furthermore, the female subjects had an obesity prevalence of 12.70% in comparison to the male subjects, whose obesity prevalence was 4.98%. The distribution pattern of subcutaneous fat was found to be mainly located in the central part of body. The high percentage of overweight and obesity along with the development of a central fat distribution pattern (neck, chest, and abdomen) in these school children is clear evidence of potential cardiovascular risk.
