| Abstract |
OBJECTIVE: To identify the consumption of alcoholic beverage and the relation with hypertension, their prevalence and associated factors, in indigenous Mura, Brazil. METHODS: A cross-sectional population-based study was conducted with 455 adult indigenous aged 18 years or more of Mura ethnics in Amazonia, Brazil. Interview was conducted and the alcohol intake was assessed by the Alcohol Use Disorders Identification Test. Blood pressure was measured in three measurements and the mean of the last two measurements was used. Physical examination included the following data: weight, height, waist and neck circumference, bioimpedance, and capillary measurement of glucose, triglycerides and cholesterol. Through multivariate Logistic regression in stepwise, the odds ratios for alcohol consumption and associated factors were identified. RESULTS: The prevalence of alcoholic beverage was 40.2%, with no significant difference for hypertension in those who drink (23.0%) and those who did not drink (29.0%). Referred hypertension in indigenous was associated to less use of alcoholic beverages (14.2% vs 24.3%, P = 0.009). After an adjusted analysis (Odds Ratio, 95% CI), there was a positive association between alcoholic drink intake and male sex (10.27, CI: 5.76-18.30), smoking (4.72, CI: 2.35-9.46) and live in rural areas (9.77, CI: 5.08-18.79). On the other hand, age (0.95, IC: 0.94-0.97), and absence of dyslipidemia (0.41, CI: 0.19-0.89) were associated to lower alcohol consumption. CONCLUSION: The prevalence of alcoholic beverage was high and associated with referred hypertension, but this association was not maintained after adjusted analysis. Changes to habits and inappropriate lifestyles in indigenous populations and living in urban areas may contribute to increase risk for cardiovascular diseases. Therefore, health policies should be implemented to meet the uniqueness of indigenous people. |

| Abstract |
Glioblastoma multiforme (GBM) is the most common and deadliest form of primary brain tumor. Despite treatment with surgery, radiotherapy, and chemotherapy with the drug temozolomide, the expected survival after diagnosis remains low. The median survival is only 14.6 months and the two-year survival is a mere 30%. One reason for this is the heterogeneity of GBM including the presence of glioblastoma cancer stem cells (GSCs). GSCs are a subset of cells with the unique ability to proliferate, differentiate, and create tumors. GSCs are resistant to chemotherapy and radiation and thought to play an important role in recurrence. In order to effectively treat GBM, a drug must be identified that can kill GSCs. The ionophore salinomycin has been shown to kill cancer stem cells and is therefore a promising future treatment for GBM. This study focuses on salinomycin's potential to treat GBM including its ability to reduce the CSC population, its toxicity to normal brain cells, its mechanism of action, and its potential for combination treatment. |

| Abstract |
Glioblastoma multiforme (GBM) is the most common primary brain tumour, and the most aggressive in nature. The prognosis for patients with GBM remains poor, with a median survival time of only 1-2 years. The treatment failure relies on the development of resistance by tumour cells and the difficulty of ensuring that drugs effectively cross the dual blood brain barrier/blood brain tumour barrier. The advanced molecular and genetic knowledge has allowed to identify the mechanisms responsible for temozolomide resistance, which represents the standard of care in GBM, along with surgical resection and radiotherapy. Such resistance has motivated the researchers to investigate new avenues for GBM treatment intended to improve patient survival. In this review, we provide an overview of major obstacles to effective treatment of GBM, encompassing biological barriers, cancer stem cells, DNA repair mechanisms, deregulated signalling pathways and autophagy. New insights and potential therapy approaches for GBM are also discussed, emphasizing localized chemotherapy delivered directly to the brain, immunotherapy, gene therapy and nanoparticle-mediated brain drug delivery. |

| Abstract |
Necrosis is a hallmark of glioblastoma (GBM) and is responsible for poor prognosis and resistance to conventional therapies. However, the molecular mechanisms underlying necrotic microenvironment-induced malignancy of GBM have not been elucidated. Here, we report that transglutaminase 2 (TGM2) is upregulated in the perinecrotic region of GBM and triggered mesenchymal (MES) transdifferentiation of glioma stem cells (GSC) by regulating master transcription factors (TF), such as C/EBPbeta, TAZ, and STAT3. TGM2 expression was induced by macrophages/microglia-derived cytokines via NF-kappaB activation and further degraded DNA damage-inducible transcript 3 (GADD153) to induce C/EBPbeta expression, resulting in expression of the MES transcriptome. Downregulation of TGM2 decreased sphere-forming ability, tumor size, and radioresistance and survival in a xenograft mouse model through a loss of the MES signature. A TGM2-specific inhibitor GK921 blocked MES transdifferentiation and showed significant therapeutic efficacy in mouse models of GSC. Moreover, TGM2 expression was significantly increased in recurrent MES patients and inversely correlated with patient prognosis. Collectively, our results indicate that TGM2 is a key molecular switch of necrosis-induced MES transdifferentiation and an important therapeutic target for MES GBM. Cancer Res; 77(18); 4973-84.

| Abstract |
BACKGROUND: Food insecurity contributes to poor health outcomes among people living with HIV. In Latin America and the Caribbean, structural factors such as poverty, stigma, and inequality disproportionately affect women and may fuel both the HIV epidemic and food insecurity. METHODS: We examined factors contributing to food insecurity among women living with HIV (WLHIV) in the Dominican Republic (DR). Data collection included in-depth, semi-structured interviews in 2013 with 30 WLHIV with indications of food insecurity who resided in urban or peri-urban areas and were recruited from local HIV clinics. In-person interviews were conducted in Spanish. Transcripts were coded using content analysis methods and an inductive approach to identify principal and emergent themes. RESULTS: Respondents identified economic instability as the primary driver of food insecurity, precipitated by enacted stigma in the labor and social domains. Women described experiences of HIV-related labor discrimination in formal and informal sectors. Women commonly reported illegal HIV testing by employers, and subsequent dismissal if HIV-positive, especially in tourism and free trade zones. Enacted stigma in the social domain manifested as gossip and rejection by family, friends, and neighbors and physical, verbal, and sexual abuse by intimate partners, distancing women from sources of economic and food support. These experiences with discrimination and abuse contributed to internalized stigma among respondents who, as a result, were fearful and hesitant to disclose their HIV status; some participants reported leaving spouses and/or families, resulting in further isolation from economic resources, food and other support. A minority of participants described social support by friends, spouses, families and support groups, which helped to ameliorate food insecurity and emotional distress. CONCLUSIONS: Addressing food insecurity among WLHIV requires policy and programmatic interventions to enforce existing laws designed to protect the rights of people living with HIV, reduce HIV-related stigma, and improve gender equality. |
