Title The school environment and sugar-sweetened beverage consumption among Guatemalan adolescents Type Journal Article
Year 2017 Publication Public Health Nutrition Abbreviated Journal (down) Public Health Nutr
Volume 20 Issue 16 Pages 2980-2987
Keywords Latin America; Nutrition policy; School health; Sugar-sweetened beverages
Abstract OBJECTIVE: The current study sought to examine Guatemalan adolescents' consumption of sugar-sweetened beverages (SSB), identify which individual-level characteristics are associated with SSB consumption and describe school characteristics that may influence students' SSB consumption. DESIGN: Within this observational pilot study, a questionnaire was used to assess students' consumption of three varieties of SSB (soft drinks, energy drinks, sweetened coffees/teas), as well as a variety of sociodemographic and behavioural characteristics. We collected built environment data to examine aspects of the school food environment. We developed Poisson regression models for each SSB variety and used descriptive analyses to characterize the sample. SETTING: Guatemala City, Guatemala. SUBJECTS: Guatemalan adolescents (n 1042) from four (two public, two private) secondary schools. RESULTS: Built environment data revealed that students from the two public schools lacked access to water fountains/coolers. The SSB industry had a presence in the schools through advertisements, sponsored food kiosks and products available for sale. Common correlates of SSB consumption included school type, sedentary behaviour, frequency of purchasing lunch in the cafeteria, and frequency of purchasing snacks from vending machines in school and off school property. CONCLUSIONS: Guatemalan adolescents frequently consume SSB, which may be encouraged by aspects of the school environment. Schools represent a viable setting for equitable population health interventions designed to reduce SSB consumption, including increasing access to clean drinking-water, reducing access to SSB, restricting SSB marketing and greater enforcement of existing food policies.

Title Association of neighbourhood food availability with the consumption of processed and ultra-processed food products by children in a city of Brazil: a multilevel analysis Type Journal Article
Year 2017 Publication Public Health Nutrition Abbreviated Journal (down) Public Health Nutr
Volume Issue Pages 1-12
Keywords Children; Food consumption; Food environment; Neighbourhood; Ultra-processed food products
Abstract OBJECTIVE: To investigate the association between neighbourhood food availability and the consumption of ready-to-consume products (RCP), either processed or ultra-processed, and unprocessed/minimally processed foods (UF-MPF) by children. DESIGN: Cross-sectional. 24 h Dietary recalls were collected from children from January 2010 to June 2011. Neighbourhood food availability data were collected from 672 food stores located within 500 m of participants' homes, using an adapted and validated instrument. Neighbourhood-level socio-economic status (SES) was obtained by calculating the mean years of household head's education level in each census tract covered by 500 m buffers. Foods that were consumed by children and/or available in the food stores were classified based on their degree of industrial processing. Multilevel random-effect models examined the association between neighbourhood food availability and children's diets. SETTING: Santos, Brazil. SUBJECTS: Children (n 513) under 10 years old (292 aged <6 years, 221 aged >/=6 years). RESULTS: The availability of RCP in food stores was associated with increased RCP consumption (P<0.001) and decreased UF-MPF consumption (P<0.001). The consumption of UF-MPF was positively associated with neighbourhood-level SES (P<0.01), but not with the availability of UF-MPF in the neighbourhood. CONCLUSIONS: Results suggest that food policies and interventions that aim to reduce RCP consumption in Santos and similar settings should focus on reducing the availability in food stores. The results also suggest that interventions should not only increase the availability of UF-MPF in lower-SES neighbourhoods, but should strive to make UF-MPF accessible within these environments.

Title Expression of CD133 and CD44 in glioblastoma stem cells correlates with cell proliferation, phenotype stability and intra-tumor heterogeneity Type Journal Article
Year 2017 Publication PloS one Abbreviated Journal (down) PLoS One

Abstract Glioblastoma (GBM) is a heterogeneous tumor of the brain with a poor prognosis due to recurrence and drug resistance following therapy. Genome-wide profiling has revealed the existence of distinct GBM molecular subtypes that respond differently to aggressive therapies. Despite this, molecular subtype does not predict recurrence or drug resistance and overall survival is similar across subtypes. One of the key features contributing to tumor recurrence and resistance to therapy is proposed to be an underlying subpopulation of resistant glioma stem cells (GSC). CD133 expression has been used as a marker of GSCs, however recent evidence suggests the relationship between CD133 expression, GSCs and molecular subtype is more complex than initially proposed. The expression of CD133, Olig2 and CD44 was investigated using patient derived glioma stem-like cells (PDGCs) in vitro and in vivo. Different PDGCs exhibited a characteristic equilibrium of distinct CD133+ and CD44+ subpopulations and the influence of environmental factors on the intra-tumor equilibrium of CD133+ and CD44+ cells in PDGCs was also investigated, with hypoxia inducing a CD44+ to CD133+ shift and chemo-radiotherapy inducing a CD133+ to CD44+ shift. These data suggest that surveillance and modulation of intra-tumor heterogeneity using molecular markers at initial surgery and surgery for recurrent GBM may be important for more effective management of GBM.
