Cancer treatment adherence among low‐income women with breast or gynecologic cancer

Abstract

The use of microorganisms as support for reduction of dissolved Pd(II) to immobilized Pd(0) nanoparticles is an environmentally friendly approach for Pd recovery from waste. To better understand and engineer Pd(0) nanoparticle synthesis, one has to consider the mechanisms by which Pd(II) is reduced on microbial surfaces. Escherichia coli, Shewanella oneidensis, and Pseudomonas putida were used as model organisms in order to elucidate the role of microbial cells in Pd(II) reduction under acidic conditions. Pd(II) was reduced by formate under acidic conditions, and the process occurred substantially faster in the presence of cells as compared to cell‐free controls. We found no difference between native (untreated) and autoclaved cells, and could demonstrate that even a non‐enzymatic protein (bovine serum albumin) stimulated Pd(II) reduction as efficiently as bacterial cells. Amine groups readily interact with Pd(II), and to specifically test their role in surface‐assisted Pd(II) reduction by formate, we replaced bacterial cells with polystyrene microparticles functionalized with amine or carboxyl groups. Amine‐functionalized microparticles had the same effect on Pd(II) reduction as bacterial cells, and the effect could be hampered if the amine groups were blocked by acetylation. The interaction with amine groups was confirmed by infrared spectroscopy on whole cells and amine‐functionalized microparticles. In conclusion, bio‐supported Pd(II) reduction on microbial surfaces is possibly mediated by a non‐enzymatic mechanism. We therefore suggest the use of amine‐rich biomaterials rather than intact cells for Pd bio‐recovery from waste. Biotechnol. Bioeng. 2012; 109:1889–1897. © 2012 Wiley Periodicals, Inc.

Inferior health-related quality of life and psychological well-being in immigrant cancer survivors: A population-based study

“…Patient navigation interventions appear promising for reducing delays before diagnosis, 26 and improving treatment adherence. 27,28,29 Only two trials targeted emotional well-being, both demonstrating efficacy in Hispanic populations. [30][31][32] There remains a need to evaluate interventions outside the Hispanic population to reduce depression and improve QOL in immigrants with cancer.…”

Effect of a breast navigation programme in a teaching hospital in Africa

“…12 On the other hand, there are breast navigation programmes that have shown high adherence to cancer care through financial support. 13,14 Telephone reminders and text messages alter the inducement and were associated with follow-up behaviour and may show effect in patients who have no support system to remind them of appointments and those who are too busy or forgetful. 15 In our study, 35.5% of women had no one to remind them of appointments and they responded better to navigation compared to their counterparts who were not navigated, though this was not statistically significant.…”

Patient Perceptions of a Comprehensive Cancer Navigation Service

“…Relatively limited in scope, those services have focussed on improving access to screening 14 , simplifying the diagnostic workup 15 , overcoming barriers to treatment 16 , assisting patients with decisionmaking 17 , or improving adherence to treatment 18 . Several have been more inclusive 19,20 .…”
