  Title Risk factors for bacteremia and central line-associated blood stream infections in children with acute myelogenous leukemia: A single-institution report Type Journal Article
  Year 2017 Publication Pediatric Blood & Cancer Abbreviated Journal Pediatr Blood Cancer

  Abstract BACKGROUND: Central line-associated blood stream infections (CLABSIs) are a source of high morbidity and mortality in children with acute myelogenous leukemia (AML). PROCEDURE: To understand the epidemiology and risk factors associated with the development of CLABSI in children with AML. METHODS: We retrospectively reviewed all patients with AML over a 5-year period between 2007 and 2011 at the Children's Hospital Colorado. Cases and controls were classified on the basis of the presence of a CLABSI as defined by the National Healthcare Safety Network. RESULTS: Of 40 patients in the study, 25 (62.5%) developed at least one CLABSI during therapy. The majority of CLABSIs were due to oral or gastrointestinal organisms (83.0%). Skin organisms accounted for 8.5%. In a multivariable analysis, the strongest risk factors associated with CLABSI were diarrhea (odds ratio [OR] 6.7, 95% confidence interval [CI] 1.6-28.7), receipt of blood products in the preceding 4-7 days (OR 10.0, 95%CI 3.2-31.0), not receiving antibiotics (OR 8.3, 95%CI 2.8-25.0), and chemotherapy cycle (OR 3.5, 95%CI 1.4-8.9). CLABSIs led to increased morbidity, with 13 cases (32.5%) versus two controls (1.9%) requiring transfer to the pediatric intensive care unit (P < 0.001). Three (7.5%) of 40 CLABSI events resulted in or contributed to death. CONCLUSIONS: Intensified line care efforts cannot eliminate all CLABSIs in the patients with AML. Exploring the role of mucosal barrier breakdown and/or the use of antibiotic prophylaxis may be effective strategies for further prevention of CLABSIs, supporting ongoing trials in this patient population.

  Abstract Staphylococcus aureus is frequently isolated in the setting of infections of indwelling medical devices, which are mediated by the microbe's ability to form biofilms on a variety of surfaces. Biofilm-embedded bacteria are more resistant to antimicrobial agents than their planktonic counterparts and often cause chronic infections and sepsis, particularly in patients with prolonged hospitalizations. In this study, we demonstrate that sustained nitric oxide-releasing nanoparticles (NO-np) interfere with S. aureus adhesion and prevent biofilm formation on a rat central venous catheter (CVC) model of infection. Confocal and scanning electron microscopy showed that NO-np-treated staphylococcal biofilms displayed considerably reduced thicknesses and bacterial numbers compared to those of control biofilms in vitro and in vivo, respectively. Although both phenotypes, planktonic and biofilm-associated staphylococci, of multiple clinical strains were susceptible to NO-np, bacteria within biofilms were more resistant to killing than their planktonic counterparts. Furthermore, chitosan, a biopolymer found in the exoskeleton of crustaceans and structurally integrated into the nanoparticles, seems to add considerable antimicrobial activity to the technology. Our findings suggest promising development and translational potential of NO-np for use as a prophylactic or therapeutic against bacterial biofilms on CVCs and other medical devices.

  Title [Quitting smoking and willingness to pay for cessation in Panama] Type Journal Article
  Year 2017 Publication Salud Publica de Mexico Abbreviated Journal Salud Publica Mex  
  Volume (down) 59Suppl 1 Issue Suppl 1 Pages 54-62  
  Keywords  
  Abstract Objective:: To characterize the desire for cessation and willingness to pay for abandonment therapy. Materials and methods:: The data source is the Global Adult Tobacco Survey (GATS). Cessation and willingness to pay were characterized by sociodemographic (SD) and socioeconomic (SE) variables. Logistic regressions were performed to estimate associations. Results:: A greater desire for cessation was observed in variables: women, education, non-governmental and inactive employees, rural areas, occasional smokers and middle income, and greater willingness to pay, in: education, over 60 years old, non-governmental, self-employed, urban area, occasional smokers and low median income. Conclusions:: There is a high relation between the desire for abandonment, and willingness to pay with SD and SE variables. Cessation therapies can be applied in work centers, and require a change of focus in the intervention.
