  Title Eradication of Staphylococcus aureus Biofilm Infections Using Synthetic Antimicrobial Peptides Type Journal Article
  Year 2017 Publication The Journal of Infectious Diseases Abbreviated Journal J Infect Dis  
  Volume 215 Issue 6 Pages (down) 975-983  
  Keywords Animals; Anti-Bacterial Agents/*pharmacology; Biofilms/*drug effects; Catheter-Related Infections/*drug therapy; Cytokines/blood; Disease Models, Animal; Humans; Methicillin-Resistant Staphylococcus aureus/*drug effects; Microbial Sensitivity Tests; Peptides/*pharmacology; Peptides, Cyclic/pharmacology; Rats; Rats, Sprague-Dawley; Staphylococcal Infections/*drug therapy; Vancomycin/administration & dosage; *Staphylococcus aureus; *antimicrobial peptides (AMPs); *biofilm; *catheter lock solution (CLS)  
  Abstract Here, we demonstrate that antimicrobial peptides (AMPs) are an effective antibiofilm treatment when applied as catheter lock solutions (CLSs) against S. aureus biofilm infections. The activity of synthetic AMPs (Bac8c, HB43, P18, Omiganan, WMR, Ranalexin, and Polyphemusin) was measured against early and mature biofilms produced by methicillin-resistant S. aureus and methicillin-susceptible S. aureus isolates from patients with device-related infections grown under in vivo-relevant biofilm conditions. The cytotoxic and hemolytic activities of the AMPs against human cells and their immunomodulatory potential in human blood were also characterized. The D-Bac8c2,5Leu variant emerged as the most effective AMP during in vitro studies and was also highly effective in eradicating S. aureus biofilm infection when used in a CLS rat central venous catheter infection model. These data support the potential use of D-Bac8c2,5Leu, alone or in combination with other AMPs, in the treatment of S. aureus intravenous catheter infections.

  Title Impact on Area-Level Physical Activity Following the Implementation of a Fitness Zone in Montevideo, Uruguay Type Journal Article
  Year 2017 Publication Journal of Physical Activity & Health Abbreviated Journal J Phys Act Health  
  Volume 14 Issue 11 Pages (down) 883-887  
  Keywords Soparc; observation; parks  
  Abstract BACKGROUND: The aim of the study was to measure the level of physical activity (PA) of the users of an urban park before and after the installation of 2 fitness zones (FZs) and to assess the impact of that intervention on the users' level of PA. METHODS: The System for Observing Play and Recreation in Communities method was applied in the urban plaza Liber Seregni in Montevideo (Uruguay): 14 different areas were mapped and then recategorized as fitness (for PAs, including sports), green, and paved zones. Observations were made in the spring (Sep-Oct) of 2011 and 2014, before and after placing 2 FZs. Participation was analyzed by gender, year, mapped areas, and zones, and significant differences were assessed using the chi2 test. RESULTS: In total, 7342 individuals (4091 men and 3251 women) were observed. A greater number of people with intense PA could be seen in the FZ, with significant differences between 2011 (45%) and 2014 (70%; P < .05). CONCLUSION: This is the first longitudinal study on the impact of an intervention to increase the level of PA in public spaces in Uruguay. Higher intensity levels of PA and fewer sedentary people were observed after the installation of the FZ.

  Title AIDS Service Organization Access Among African, Caribbean and Other Black Residents of an Average Canadian City Type Journal Article
  Year 2017 Publication Journal of Immigrant and Minority Health Abbreviated Journal J Immigr Minor Health  
  Volume 19 Issue 4 Pages (down) 851-860  
  Keywords African; Black people; Caribbean; Hiv/Aids; Health disparities; Health services research; Immigrant health; Minority health  
  Abstract Due to heightened vulnerability to HIV/AIDS, African, Caribbean and Black (ACB) communities are priority groups for prevention and intervention services in Canada. However, it is not clear which factors may affect ACB communities' access to these services. We evaluated access to the local AIDS service organization (ASO) in Middlesex-London by using data from the Black, African and Caribbean Canadian Health Study. Modified Poisson regression was used to obtain prevalence risk ratios for factors associated with three measures of access: familiarity with the ASO, willingness to access, and realized access. In adjusted analyses, older ACB community members were more likely to be familiar with the ASO, willing to access it, and have actually gone there. Canadian-born participants were less likely to have been to the ASO than recent immigrants. These results have implications for reaching specific segments of ACB communities for HIV/AIDS-related services in Canada.

  Title Salinomycin's potential to eliminate glioblastoma stem cells and treat glioblastoma multiforme (Review) Type Journal Article
  Year 2017 Publication International Journal of Oncology Abbreviated Journal Int J Oncol  
  Volume 51 Issue 3 Pages (down) 753-759  
  Keywords  
  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.
