RESUMO

Parental restriction of food intake has been associated with heightened eating disorder psychopathology in some longitudinal research. Yet, relatively little is known about the determinants of restrictive feeding practices. This cross-sectional study explored the association between parents' anti-fat attitudes and their use of restrictive feeding practices in a mixed British (41.10% England, 39.90% Scotland, 4.20% Other) and Irish (14.80%) sample. Parents and caregivers (N = 472; 94.10% female; 70.90% university level education) of children between the ages of 4-8 (48.20% female; 91.10% rated as "normal weight" by their parents) completed self-report questionnaires assessing their anti-fat attitudes (dislike, fear, and blame subscales), use of restrictive feeding practices (for weight control, health purposes, and covert restriction), and how influential their child's body-weight and -shape is for their perception of themselves as parents. Overall, our hypothesis that parental anti-fat attitudes would be significantly associated with restrictive feeding practices was supported. Anti-fat attitudes related to disliking higher body-weight people and blaming parents for their child's weight were significant predictors of all forms of restrictive feeding (all ps < .05). However, anti-fat attitudes related to fearing being a higher body-weight were not significant predictors of restrictive feeding for the purposes of health nor for covert restriction (ps > .05). Additionally, our hypothesis that the associations between anti-fat attitudes and restrictive feeding practices would be stronger for parents for whom their child's body-weight and -shape more strongly influenced how they judged themselves as parents was not supported (the interaction term was not significant in two out of three analyses). Future research is needed to investigate these associations across time and in samples of higher body-weight children.

RESUMO

INTRODUCTION: Vascular endothelial growth factor A (VEGF-A) is a chemokine that induces proliferation and migration of vascular endothelial cells and is essential for both physiological and pathological angiogenesis. It is known for its high heritability (> 60%) and involvement in most common morbidities, which makes it a potentially interesting biomarker. Large GWAS studies have already assessed polymorphisms related to VEGF-A. However, no previous research has provided epigenome-wide insight in regulation of VEGF-A. METHODS: VEGF-A concentrations of healthy participants from the STANISLAS Family Study (n = 201) were comprehensively assessed for association with DNA methylation. Genome-wide DNA methylation profiles were determined in whole blood DNA using the 450K Infinium BeadChip Array (Illumina). VEGF-A concentration in PBMC extracts was detected using a high-sensitivity multiplex Cytokine Array (Randox Laboratories, UK). RESULTS: Epigenome-wide association analysis identified 41 methylation sites significantly associated with VEGF-A concentrations derived from PBMC extracts. Twenty CpG sites within 13 chromosomes reached Holm-Bonferroni significance. Significant values ranged from P = 1.08 × 10-7 to P = 5.64 × 10-15. CONCLUSION: This study exposed twenty significant CpG sites linking DNA methylation to VEGF-A concentration. Methylation detected in promoter regions, such as TPX2 and HAS-1, could explain previously reported associations with the VEGFA gene. Methylation may also help in the understanding of the regulatory mechanisms of other genes located in the vicinity of detected CpG sites.

RESUMO

Few quantitative studies have examined the rate of exposure to traumatic events during immigration among Hispanics or its relation to mental health outcomes. Failing to capture traumatic events that occur during immigration may impede investigations of trauma and related mental health disparities with Hispanics. In order to better understand the need for immigration-related trauma assessment, interviews were conducted with 131 immigrant Hispanic youth. First, youth completed a comprehensive trauma assessment interview. Items were added to the interview to assess if each traumatic event occurred during the process of immigration. An immigration-focused module was then added to the end of the assessment. A substantial minority of youths reported experiencing a traumatic event during immigration (n = 39; 29.8%). The majority of these were not captured by the standard trauma assessment (n = 32; 82.1% of those with in-transit trauma). Of these, the majority stated that the process of immigration itself was traumatic, but had not indicated experiencing any event assessed during the standard trauma assessment (n = 28; 87.5% of those with unidentified in-transit trauma). The traumatic events that were not captured during the standard trauma assessment significantly predicted both depression (p < .001) and PTSD symptoms (p = .012). Results suggest that standard trauma assessments may not capture traumatic events that occur during immigration for Hispanic youth. Failing to capture these events during trauma assessment may have large implications for research on trauma-related mental health disparities, as the events that were not captured overlapped significantly with depression and PTSD.


Pocas investigaciones cuantitativas han examinado la tasa de trauma que ocurre entre Hispanos durante el proceso de inmigración a los Estados Unidos. Cuando evaluaciones de trauma no capturan trauma de inmigración, puede impedir investigaciones de disparidades de salud mental y trauma para Hispanos. Para entender mejor la necesidad de incluir componentes de inmigración en evaluaciones de trauma, se entrevistaron 131 adolescentes Hispanos. Primero, los adolescentes cumplieron una entrevista comprensiva y estándar de trauma. Se añadieron preguntas a la entrevista para determinar si el evento ocurrió durante inmigración. Luego, se añadió una sección enfocada en inmigración. Una menoridad sustancial de adolescentes indicó trauma durante inmigración (n = 39; 29.8%). La mayoría de estos casos no se capturaron durante la evaluación estándar (n = 32; 82.1% de los quienes indicaron trauma durante inmigración). De estos, la mayoría indicaron que fue el proceso de inmigración que fue traumático (n = 28; 87.5% de los quienes no indicaron trauma durante la evaluación estándar). Los eventos los cuales no se capturaron en la evaluación estándar correlacionaron con síntomas ambos de depresión (p < .001) y estrés postraumático (p = .012). Los resultados sugieren que evaluaciones estándares de trauma no capturan eventos traumáticos que ocurren durante inmigración para adolescentes Hispanos. Además, el no capturar estos eventos tal vez tiene implicaciones para investigaciones de disparidades de trauma y salud mental, porque los eventos que no se capturaron correlacionaron con depresión y el estrés postraumático.

RESUMO

Limited attention has been paid to the development and evaluation of interventions that reduce risk for substance use, while also targeting trauma-related psychopathology among maltreated adolescents. Risk Reduction through Family Therapy (RRFT) is a multicomponent treatment that integrates principles and interventions from existing empirically supported treatments. The purpose of the current study was to evaluate the feasibility of implementation and initial efficacy of RRFT through an open pilot trial involving a small sample (N = 10) of female adolescents (aged 13-17 years) who had experienced at least one memorable sexual assault in their lifetime. Measures of substance use and substance use risk factors (e.g., family functioning), posttraumatic stress disorder (PTSD), and depression symptoms were assessed pre- and posttreatment as well as at 3-month and 6-month posttreatment follow-up assessments. Results demonstrated reductions in multiple areas, including substance use and related risk factors, PTSD, and depression symptoms, which were maintained through follow-up. Clinical implications and future directions with this line of research are discussed.

RESUMO

BACKGROUND: Efforts to simplify the collection and shipping of specimens for HIV drug-resistance testing in resource-limited settings are needed as antiretroviral therapy increases worldwide. OBJECTIVE: To evaluate the reliability and practicality of using dried blood spots (DBS) for HIV-1 drug-resistance testing with the Trugene HIV-1 genotyping assay. STUDY DESIGN: Nucleic acids from 33 DBS and counterpart plasma specimens were extracted using the Nuclisens MiniMAG system and genotyped using the Trugene HIV-1 genotyping assay. Results were evaluated for sensitivity, accuracy, and reproducibility. RESULTS: A genotype was obtained for 33 (100%) plasma specimens and 26 (78.8%) DBS specimens, including 19 of 21 (90.5%) DBS specimens with a viral load greater than 6000 copies/mL. The mean nucleotide sequence concordance for the 940-nucleotide region evaluated was 99.3% for 26 DBS and plasma pairs, and 99.2% for 15 replicate DBS pairs. All 58 resistance-associated mutations detected in plasma specimens were detected in the corresponding DBS specimens. CONCLUSIONS: We show that DBS can be reliably and accurately genotyped using standard clinical assay methods, offering a practical alternative to plasma. This method is well suited for pre-treatment resistance testing and has potential for use in monitoring drug resistance in ART-treated individuals.
