Impact of an educational intervention on breast cancer knowledge in western Kenya.

Our objective was to assess the effectiveness of educational sessions that accompanied breast cancer screening events in three communities in western Kenya between October and November 2013. Five hundred and thirty-two women were recruited to complete a test of breast cancer-relevant knowledge and randomly allocated to 'pre-test' or 'post-test' groups that immediately preceded or followed participation in the educational sessions. The education was organized as a presentation by health professionals and focused mainly on causes of breast cancer, early and late cancer presentation signs, high-risk groups, screening methods to find early-stage breast cancer, self-breast exam procedures and treatment options for this disease. Participants were invited to ask questions and practice finding nodules in silicone breast models. The median age was 35 years (interquartile range: 28-45), and 86% had not undergone breast cancer screening previously. Many individual items in our test of knowledge showed statistically significant shifts to better-informed responses. When all items in the assessment questionnaire were scored as a 'test', on average there was a 2.80 point (95% CI: 2.38, 3.22) significant improvement in knowledge about breast cancer after the educational session. Our study provides evidence for the effectiveness of an educational strategy carefully tailored for women in these communities in Kenya.

BARRIERS TO UPTAKE OF BREAST CANCER SCREENING IN KENYA.

OBJECTIVES: To conduct clinical breast cancer screening in three sites in Western Kenya and explore community barriers to screening uptake. DESIGN: Cross-sectional study. SETTING: Western Kenya specifically, Mosoriot, Turbo, and Kapsokwony. SUBJECTS: Community members (18 years and older) who did not attend the screening events. OUTCOME MEASURE: The outcome measure was having heard about the breast cancer screening events. Both structured and open-ended questions were used for data collection. Item frequency, correlations, and content analyses were performed. RESULTS: A total of 733 community members were surveyed (63% women, median age 33 years, IQR = 26-43). More than half (55%) of respondents had heard about the screening but did not attend. The majority of those who had heard about this particular screening had knowledge of screening availability in general (45% vs. 25%, p < 0.001). Only 8.0% of those who heard and 6.0% of those who had not heard of the screening event had previously undergone clinical breast exam (p = 0.20). Reasons for not attending the screening event were personal factors, including busy schedule (41.0%), perceived low personal risk (12.7%), lack of transport (4.2%), as well as health facility factors such as poor publicity (14.4%) and long queues (8.7%). CONCLUSION: Barriers to breast cancer screening uptake were associated with inadequate publicity, perceived long waits at event and busy lives among community women.

8-Hydroxyquinolines with the potential for long-term anticaries activity: design, synthesis, and in vitro evaluation.

8-Hydroxyquinolyl benzoate and 8-hydroxyquinolyl para-(fluorosulfonyl)benzoate have been synthesized and evaluated in vitro as antimicrobial and antiplaque agents. Both compounds inhibited the growth of cultures of the following genera: Streptococcus, Staphylococcus, Actinomyces, Lactobacillus, Veillonella, and Candida. Minimum inhibitory concentrations ranged from 0.98 to 62 microgram/ml. Extracted human teeth pretreated with 1% solutions of either compound and rinsed with distilled water exhibited reduced in vitro plaque formation for 48 hours. These results indicate that the in vitro antiplaque activity of 8-hydroxyquinolines can be enhanced by attaching the appropriate side chain in the 8-position.
