“ObjectiveAlthough African American (AA) men are at elevated risk for prostate cancer, medical guidelines do not present consistent screening recommendations for this group. However, all guidelines stress the need for screening decision making with a provider. This study evaluated the effectiveness of a brochure for the female partners of AA men, designed to help promote such discussion on
the part of their mates. We also explored the effect of the partner’s monitoring style (i.e., the extent to which the partner typically attends to health threats) on promoting discussion.
MethodsFemale partners of AA men (N=231) were randomized to receive either a prostate cancer screening Centers for Disease Control brochure for AA men, combined with a partner’ brochure containing strategies to find more promote selleck men’s initiation of a provider visit to discuss screening, or the Centers for Disease Control brochure only and completed preintervention and post-intervention surveys online.
ResultsThe message groups did not differ on taking active steps to engage in provider discussion: relative
risk ratio (RRR)=0.99, p=.98; thinking about it: RRR=1.13, p=.74. However, among partners who received the partner brochure, monitoring style was associated with thinking about initiating a provider visit’ on the part of the mate (RRR=1.74, p<.01). Across conditions, monitoring style was also associated with taking active steps to initiate a provider visit’ on the part of the mate (RRR=1.38, p<.05).
ConclusionsHigh monitoring partners may be effective in influencing their AA mates to initiate provider discussion, particularly when tailored messaging is provided. Copyright (c) 2013 John Wiley & Sons, Ltd.”
“We are testing the compatibilization of the chitosan/PLA blends by addition of diisocyanate and at studying the effect of several MDI concentrations
CDK 抑制剂 (0.5 and 2.5% of the global blend mass, w/w). To evaluate the MDI efficiency as a compatibilizer of chitosan/PLA blends, we worked with the following methods: IRTF spectra with higher peak at 1558 cm(-1) is due to the -NH bonds that exist in urea and urethane, thermal properties shows that the temperature of the endothermic peaks of the chitosan/PLA blends with MDI is very close to the temperature of pure chitosane and SEM micrography shows that MDI addition decreases the PLA particles size in the chitosan mixture; they also comply with the compatibilization theory. After that the mechanical properties have been characterized: we can notice that the MDI compatibilized chitosan/PLA blends have a higher Young’s modulus than the noncompatibilized blends. we are showed that the use of 0.5% MDI is not enough sufficient to obtain a compatibilization, because a part of the MDI can be consumed by water. The addition of MDI increases the performance of the mechanical properties of the blends.
