| Abstract |
Knowledge on the occurrence of multimorbidity is important from the viewpoint of public policies, as this condition increases the consumption of medicines as well as the utilization and expenses of health services, affecting life quality of the population. The objective of this study was to estimate prevalence of self-reported multimorbidity in Brazilian adults (>/=18 years old) according to socioeconomic and demographic characteristics. A descriptive study is presented herein, based on data from the National Health Survey, which was a household-based survey carried out in Brazil in 2013. Data on 60,202 adult participants over the age of 18 were included. Prevalences and its respective confidence intervals (95%) were estimated according to sex, age, education level, marital status, self-reported skin color, area of residence, occupation and federative units (states). Poisson regression models univariate and multivariate were used to evaluate the association between socioeconomic and demographic variables with multimorbidity. To observe the combinations of chronic conditions the most common groups in pairs, trios, quartets and quintets of chronic diseases were observed. The prevalence of multimorbidity was 23.6% and was higher among women, in individuals over 60 years of age, people with low educational levels, people living with partner, in urban areas and among unemployed persons. The states of the South and Southeast regions presented higher prevalence. The most common groups of chronic diseases were metabolic and musculoskeletal diseases. The results demonstrated high prevalence of multimorbidity in Brazil. The study also revealed that a considerable share of the economically active population presented two or more chronic diseases. Data of this research indicated that socioeconomic and demographic aspects must be considered during the planning of health services and development of prevention and treatment strategies for chronic diseases, and consequently, multimorbidity. |

| Abstract |
PURPOSE: To determine if there is an association between the incidental radiation dose to the subventricular zone and survival in patients with glioblastoma multiforme treated with surgery, radiotherapy and temozolomide. METHODS AND MATERIALS: Sixty-five patients, treated between 2006 and 2015, were included in this retrospective study. The doses (75th percentile; p75) administered to the ipsilateral, contralateral and bilateral subventricular zone were compared to overall survival and progression-free survival using Cox proportional hazards models. Covariates included: age, sex, surgery, tumor location, and concomitant and adjuvant temozolomide. RESULTS: Median progression-free survival and overall survival were 11.5 +/- 9.96 and 18.8 +/- 18.5 months, respectively. The p75 doses to the ipsilateral, contralateral and bilateral subventrivular zone were, respectively, 57.30, 48.8, and 52.7 Gy. Patients who received a dose >/=48.8 Gy in the contralateral subventricular zone had better progression-free survival than those who received lower doses (HR 0.46; 95% CI 0.23-0.91 P = 0.028). This association was not found for overall survival (HR 0.60; 95% CI 0.30-1.22 P = 0.16). Administration of adjuvant temozolomide was significantly associated with improved progression-free survival (HR 0.19; 95% CI 0.09-0.41 P < 0.0001) and overall survival (HR 0.11; 95% CI 0.05-0.24 P = 0.001). In the subgroup of 46 patients whose O6-methylguanine-DNA methyltransferase gene promoter status was known, the methylation had no effect on either progression-free survival (P = 0.491) or overall survival (P = 0.203). CONCLUSION: High-dose radiation in the contralateral subventricular zone was associated with a significant improvement in progression-free survival but not overall survival in patients treated for glioblastoma multiforme. |

| Abstract |
This study aimed to describe the simultaneity of risk factors for chronic non-communicable diseases among the elderly (</= 60 years) in a city in Southern Brazil. This was a cross-sectional, population-based study of 1,451 elderly in 2013. Cluster analysis was applied to selected risk factors (smoking, alcohol consumption, excess weight, and physical inactivity). Logistic regression was used to assess the association between simultaneity of risk factors and socio-demographic variables. The most frequent cluster in men (18.1%) and women (30.7%) was physical inactivity + excess weight. The cluster alcohol consumption + excess weight exceeded the expected level in men (O/E = 1.27; 95%CI: 1.01; 1.59) and women (O/E = 1.72; 95%CI: 1.35; 2.20). The presence of two or more risk factors in the elderly population (88.1%) points to the need for specific interventions for this population to fight risk factors simultaneously rather than separately. |

| Abstract |
Gliomas, and in particular glioblastoma multiforme, are aggressive brain tumors characterized by a poor prognosis and high rates of recurrence. Current treatment strategies are based on open surgery, chemotherapy (temozolomide) and radiotherapy. However, none of these treatments, alone or in combination, are considered effective in managing this devastating disease, resulting in a median survival time of less than 15 months. The efficiency of chemotherapy is mainly compromised by the blood-brain barrier (BBB) that selectively inhibits drugs from infiltrating into the tumor mass. Cancer stem cells (CSCs), with their unique biology and their resistance to both radio- and chemotherapy, compound tumor aggressiveness and increase the chances of treatment failure. Therefore, more effective targeted therapeutic regimens are urgently required. In this article, some well-recognized biological features and biomarkers of this specific subgroup of tumor cells are profiled and new strategies and technologies in nanomedicine that explicitly target CSCs, after circumventing the BBB, are detailed. Major achievements in the development of nanotherapies, such as organic poly(propylene glycol) and poly(ethylene glycol) or inorganic (iron and gold) nanoparticles that can be conjugated to metal ions, liposomes, dendrimers and polymeric micelles, form the main scope of this summary. Moreover, novel biological strategies focused on manipulating gene expression (small interfering RNA and clustered regularly interspaced short palindromic repeats [CRISPR]/CRISPR associated protein 9 [Cas 9] technologies) for cancer therapy are also analyzed. The aim of this review is to analyze the gap between CSC biology and the development of targeted therapies. A better understanding of CSC properties could result in the development of precise nanotherapies to fulfill unmet clinical needs. |

| Abstract |
Tissue transglutaminase (tTG), a dual-function enzyme with GTP-binding and acyltransferase activities, has been implicated in the survival and chemotherapy resistance of aggressive cancer cells and cancer stem cells, including glioma stem cells (GSCs). Using a model system comprising two distinct subtypes of GSCs referred to as proneural (PN) and mesenchymal (MES), we find that the phenotypically aggressive and radiation therapy-resistant MES GSCs exclusively express tTG relative to PN GSCs. As such, the self-renewal, proliferation, and survival of these cells was sensitive to treatment with tTG inhibitors, with a benefit being observed when combined with the standard of care for high grade gliomas (i.e. radiation or temozolomide). Efforts to understand the molecular drivers of tTG expression in MES GSCs revealed an unexpected link between tTG and a common marker for stem cells and cancer stem cells, Aldehyde dehydrogenase 1A3 (ALDH1A3). ALDH1A3, as well as other members of the ALDH1 subfamily, can function in cells as a retinaldehyde dehydrogenase to generate retinoic acid (RA) from retinal. We show that the enzymatic activity of ALDH1A3 and its product, RA, are necessary for the observed expression of tTG in MES GSCs. Additionally, the ectopic expression of ALDH1A3 in PN GSCs is sufficient to induce the expression of tTG in these cells, further demonstrating a causal link between ALDH1A3 and tTG. Together, these findings ascribe a novel function for ALDH1A3 in an aggressive GSC phenotype via the up-regulation of tTG, and suggest the potential for a similar role by ALDH1 family members across cancer types. |
