Title Injuries caused by firearms treated at Brazilian urgent and emergency healthcare services Type Journal Article
Year 2017 Publication (up) Ciencia & Saude Coletiva Abbreviated Journal Cien Saude Colet
Volume 22 Issue 9 Pages 2851-2860

Abstract This paper analyzes the medical care given at Brazilian urgent and emergency healthcare services to people injured by firearms in 2014. A cross-sectional study was carried out on care given to patients with firearms injuries in 24 capital cities of Brazilian states and in the Brazilian Federal District, included in the VIVA Survey. Simple and relative frequencies of the variables related to the patients and to the event were calculated, and a logistic model for complex samples was applied adopting care for firearms injuries patients as outcome. The results show the following percentages of care events as caused by firearms: 0.7% for the category 'other accidents (other than transport-related accidents)', 1.5% for self-inflicted injuries, 15.9% for injuries due to assault, and 65.1% of cases arising from legal intervention. The care given was predominantly to young male adults (age 20-39), of mixed race and with a low level of schooling. The most common injuries were: to arms and legs; and to multiple organs. The paper concludes by discussing the efforts to control firearms held by the public in Brazil, and how they can lead to severe and lethal outcomes in quarrels and interpersonal disputes.

Title Influence of incidental radiation dose in the subventricular zone on survival in patients with glioblastoma multiforme treated with surgery, radiotherapy, and temozolomide Type Journal Article
Year 2017 Publication (up) Clinical & Translational Oncology : Official Publication of the Federation of Spanish Oncology Societies and of the National Cancer Institute of Mexico Abbreviated Journal Clin Transl Oncol
Volume Issue Pages
Keywords Glioblastoma; Radiotherapy; Subventricular zone
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.

Title Irradiating the Subventricular Zone in Glioblastoma Patients: Is there a Case for a Clinical Trial? Type Journal Article
Year 2017 Publication (up) Clinical Oncology (Royal College of Radiologists (Great Britain)) Abbreviated Journal Clin Oncol (R Coll Radiol)
Volume 29 Issue 1 Pages 26-33

Abstract Glioblastoma is the most common and aggressive adult brain tumour. Over the last 10 years it has emerged that the subventricular zone (SVZ), the largest adult neural stem cell niche, has an important role in the disease. Converging evidence has implicated transformation of adult neural stems in gliomagenesis and the permissive stem cell niche in disease recurrence. Concurrently, clinical studies have suggested that SVZ involvement is a negative prognostic marker. It would follow that irradiating the SVZ may improve outcomes in glioblastoma by directly targeting this putative sanctuary site. To investigate this potential strategy, 11 retrospective studies and 1 prospective study examined the relationship between dose to the SVZ and survival outcomes in glioblastoma patients. This review summarises the theoretical underpinning of this strategy, provides a critical evaluation of the existing evidence and discusses the rationale for a clinical trial.

Title Hitting a Moving Target: Glioma Stem Cells Demand New Approaches in Glioblastoma Therapy Type Journal Article

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.

Title KCa3.1 channels and glioblastoma: in vitro studies Type Journal Article
Year 2017 Publication (up) Current Neuropharmacology Abbreviated Journal Curr Neuropharmacol
Volume Issue Pages
Keywords &gamma;H2AX foci; Aldh1a3; Gbm; GSCs; IKCa; Kcnn4; Sk4; radioresistance
Abstract Several tumor entities including brain tumors aberrantly overexpress intermediate conductance Ca2+ activated KCa3.1 K+ channels. These channels contribute significantly to the transformed phenotype of the tumor cells. By modulating membrane potential, cell volume, Ca2+ signals and the respiration chain, KCa3.1 channels in both, plasma and inner mitochondrial membrane, have been demonstrated to regulate many cellular processes such as migration and tissue invasion, metastasis, cell cycle progression, oxygen consumption and metabolism, DNA damage response and cell death of cancer cells. Moreover, KCa3.1 channels have been shown to crucially contribute to resistance against radiotherapy suggesting KCa3.1 channels as promising new targets of future anti-cancer therapies. The present article summarizes our current knowledge of the molecular signaling upstream and downstream and the effector functions of KCa3.1 channel activity in tumor cells in general and in glioblastoma cells in particular. In addition, it presents original in vitro data on KCa3.1 channel expression in subtypes of glioblastoma stem(-like) cells proposing KCa3.1 as marker for the mesenchymal subgroup of cancer stem cells. Moreover, the data suggest that KCa3.1 contributes to the therapy resistance of mesenchymal glioblastoma stem cells.
