| Abstract |
BACKGROUND: In Peru's urban communities, tobacco smoking generally starts during adolescence and smoking prevalence is highest among young adults. Each year, many attempt to quit, but access to smoking cessation programs is limited. Evidence-based text messaging smoking cessation programs are an alternative that has been successfully implemented in high-income countries, but not yet in middle- and low-income countries with limited tobacco control policies. OBJECTIVE: The objective was to assess the feasibility and acceptability of an short message service (SMS) text message-based cognitive behavioral smoking cessation program for young adults in Lima, Peru. METHODS: Recruitment included using flyers and social media ads to direct young adults interested in quitting smoking to a website where interested participants completed a Google Drive survey. Inclusion criteria were being between ages 18 and 25 years, smoking at least four cigarettes per day at least 6 days per week, willing to quit in the next 30 days, owning a mobile phone, using SMS text messaging at least once in past year, and residing in Lima. Participants joined one of three phases: (1) focus groups and in-depth interviews whose feedback was used to develop the SMS text messages, (2) validating the SMS text messages, and (3) a pilot of the SMS text message-based smoking cessation program to test its feasibility and acceptability among young adults in Lima. The outcome measures included adherence to the SMS text message-based program, acceptability of content, and smoking abstinence self-report on days 2, 7, and 30 after quitting. RESULTS: Of 639 participants who completed initial online surveys, 42 met the inclusion criteria and 35 agreed to participate (focus groups and interviews: n=12; validate SMS text messages: n=8; program pilot: n=15). Common quit practices and beliefs emerged from participants in the focus groups and interviews informed the content, tone, and delivery schedule of the messages used in the SMS text message smoking cessation program. A small randomized controlled pilot trial was performed to test the program's feasibility and acceptability; nine smokers were assigned to the SMS text message smoking cessation program and six to a SMS text message nutrition program. Participant retention was high: 93% (14/15) remained until day 30 after quit day. In all, 56% of participants (5/9) in the SMS text message smoking cessation program reported remaining smoke-free until day 30 after quit day and 17% of participants (1/6) in the SMS text message nutrition program reported remaining smoke-free during the entire program. The 14 participants who completed the pilot reported that they received valuable health information and approved the delivery schedule of the SMS text messages. CONCLUSIONS: This study provides initial evidence that a SMS text message smoking cessation program is feasible and acceptable for young adults residing in Lima. |

| Abstract |
The objective of this study was to identify the food vendor distribution profile of the city of Florianopolis, Santa Catarina State, Brazil, and investigate its association with the socioeconomic and demographic characteristics of different municipal regions. This descriptive, cross-sectional study obtained the location of food vendors from secondary data from different institutional sources. The density of different types of food vendors per 1,000 inhabitants in each municipal weighted area was calculated. The Kruskal-Wallis test compared the mean density of food vendors and the weighted income areas. The lowest-income regions had the lowest density of butchers, snack bars, supermarkets, bakeries/pastry shops, natural product stores, juice bars, and convenience stores. The identification of these areas may encourage the creation of public policies that facilitate healthy food startups and/or maintenance of healthy food vendors, especially in the lowest-income regions. |

| Abstract |
Glioblastoma (GBM) is a primary brain cancer that contains populations of stem-like cancer cells (GSCs) that home to specialized perivascular niches. GSC interactions with their niche influence self-renewal, differentiation and drug resistance, although the pathways underlying these events remain largely unknown. Here, we report that the integrin alphavbeta8 and its latent transforming growth factor beta1 (TGFbeta1) protein ligand have central roles in promoting niche co-option and GBM initiation. alphavbeta8 integrin is highly expressed in GSCs and is essential for self-renewal and lineage commitment in vitro. Fractionation of beta8high cells from freshly resected human GBM samples also reveals a requirement for this integrin in tumorigenesis in vivo. Whole-transcriptome sequencing reveals that alphavbeta8 integrin regulates tumor development, in part, by driving TGFbeta1-induced DNA replication and mitotic checkpoint progression. Collectively, these data identify the alphavbeta8 integrin-TGFbeta1 signaling axis as crucial for exploitation of the perivascular niche and identify potential therapeutic targets for inhibiting tumor growth and progression in patients with GBM.Oncogene advance online publication, 7 August 2017; doi:10.1038/onc.2017.248. |

| Abstract |
This study quantified the effects of traffic restrictions on diesel fuel heavy vehicles (HVs) on the air quality of the Bandeirantes corridor using hourly data obtained by continuous monitoring of traffic and air quality at sites located on this avenue. The study addressed the air quality of a city impacted by vehicular emissions and that PM10 and NOX concentrations are mainly due to diesel burning. Data collection was split into two time periods, a period of no traffic constraint on HVs (Nov 2008 and 2009) and a period of constraint (Nov 2010, 2011 and 2012). We found that pollutants on this corridor, mainly PM10 and NOX, decreased significantly during the period from 2008 to 2012 (28 and 43%, 15.8 and 86.9 ppb) as a direct consequence of HV traffic restrictions (a 72% reduction). Rebound effects in the form of increased traffic of light vehicles (LVs) during this time had impacts on the concentration levels, explaining the differences between rates of reduction in HV traffic and pollutants. Reductions in the number of trucks resulted in longer travel times and increased traffic congestion as a consequence of the modal shift towards LVs. We found that a 51% decrease in PM10 (28.8 mug m-3) was due to a reduction in HV traffic (vehicle emissions were estimated to be 71% of total sources, 40.1 mug m-3). This percentage was partially offset by 10% more PM10 emissions related to an increase in LV traffic, while other causes, such as climatic conditions, contributed to a 13% increase in PM10 concentrations. The relationships analyzed in this research served to highlight the need to apply urban transport policies aimed at decreasing pollutant concentrations in Sao Paulo, especially in heavily congested urban corridors on working days. |

| Abstract |
BACKGROUND: Glioblastoma multiforme (GBM) continues to devastate patients and outfox investigators and clinicians despite the preponderance of research directed at its biology, pathogenesis and therapeutic advances. GBM routinely outlasts multidisciplinary treatment protocols, almost inevitably recurring in a yet more aggressive and resistant form with distinct genetic differences from the original tumor. Attempts to glean further insight into GBM point increasingly toward a subpopulation of cells with a stem-like phenotype. These cancer stem cells, similar to those now described in a variety of malignancies, are capable of tumorigenesis from a population of susceptible cells. CONCLUSIONS: Glioma stem cells have thus become a prevalent focus in GBM research for their presumed role in development, maintenance and recurrence of tumors. Glioma stem cells infiltrate the white matter surrounding tumors and often evade resection. They are uniquely suited both biochemically and environmentally to resist the best therapy currently available, intrinsically and efficiently resistant to standard chemo- and radiotherapy. These stem cells create an extremely heterogenous tumor that to date has had an answer for every therapeutic question, with continued dismal patient survival. Targeting this population of glioma stem cells may hold the long-awaited key to durable therapeutic efficacy in GBM. |
