Using the right messaging strategies, churches can help promote behavior change. Frequencies of disease-specific messages in 21 African-American churches were compared to overall and cancer-specific mortality and morbidity rates as well as church-level variables. Disease messages were found in 1025 of 2166 items. Frequently referenced topics included cancer (n = 316), mental health conditions (n = 253), heart disease (n = 246), and infectious diseases (n = 220). Messages for lung and colorectal cancers appeared at low frequency despite high mortality rates in African-American communities. Season, church size, and denomination showed significant associations with health messages. Next steps include testing messaging strategies aimed at improving the health of churchgoing communities.

We evaluated the impact of body mass index (BMI) and lifestyle risk factors on ethnic disparity in diabetes incidence among 89 198 Asian, Native Hawaiian, and white participants of the Multiethnic Cohort who completed multiple questionnaires. After 12 years of follow-up, 11 218 new cases were identified through self-report and health plan linkages. BMI was lowest in Chinese/Koreans, Japanese, and Filipinos (22.4, 23.5, and 23.9 kg/m(2)). Using Cox regression, the unadjusted hazard ratios were 1.9 (Chinese/Korean), 2.1 (Japanese, Mixed-Asian), 2.2 (Filipino), 2.5 (Native Hawaiian), and 2.6 (part-Asian) as compared with whites. With BMI added, the risk for Japanese, Filipinos, Chinese/Koreans, and mixed-Asians increased (8%-42%) but declined in part-Asians and Native Hawaiians (17%-31%). When lifestyle and dietary factors were also included, the risk was attenuated in all groups (6%-14%). Despite their lower BMI, Asian Americans have a higher diabetes risk than whites, but dietary and lifestyle factors do not account for the excess risk., (© 2014 APJPH.)

Background: Quality of life (QoL) for patients with inflammatory skin disease can be significant, but has been evaluated in just one study in dermatomyositis (DM)., Objective: We sought to examine the relationship between the Cutaneous Dermatomyositis Area (CDASI) and Severity Index, a DM-specific cutaneous severity instrument, and various QoL study instruments and to determine the impact of DM on QoL., Methods: Skin-specific QoL instruments, the Skindex and the Dermatology Life Quality Index, and global medical QoL instruments, the Short Form 36 and the Health Assessment Questionnaire-Disability Index, were used. Pruritus was evaluated by a visual analog scale and a 0-to-10 scale in DM and cutaneous lupus erythematosus (CLE) populations, respectively., Results: There was a significant correlation between the CDASI and all skin-specific QoL scores (lowest P = .0377). Using the Short Form 36, DM population was found to have significantly worse QoL scores than the general population with the exception of bodily pain (all subscore P values < .01). Furthermore, DM had a significantly lower vitality score, representing energy level, compared with CLE, hypertension, diabetes, and recent myocardial infarction scores (lowest P = .003). There was a significantly lower mental health score, representing overall mood, to all compared diseases except CLE and clinical depression (P values < .01 when significant). We found that DM produces more pruritus than CLE (P < .0001)., Limitations: A larger patient population needs to be studied to further assess QoL in patients with DM., Conclusion: We conclude that DM has a large impact on QoL, even when compared with other diseases, and that DM skin disease activity correlates with a poorer QoL., (Published by Mosby, Inc.)

A hallmark of metastasis is organ specificity; however, little is known about the underlying signaling pathways responsible for the colonization and growth of tumor cells in target organs. Since tyrosine kinase receptor activation is frequently associated with prostate cancer progression, we have investigated the role of a common signaling intermediary, activated Ras, in prostate cancer metastasis. Three effector pathways downstream of Ras, Raf/extracellular signal-regulated kinase (ERK), phosphatidylinositol 3-kinase, and Ral guanine nucleotide exchange factors (RalGEFs), were assayed for their ability to promote the metastasis of a tumorigenic, nonmetastatic human prostate cancer cell line, DU145. Oncogenic Ras promoted the metastasis of DU145 to multiple organs, including bone and brain. Activation of the Raf/ERK pathway stimulated metastatic colonization of the brain, while activation of the RalGEF pathway led to bone metastases, the most common organ site for prostate cancer metastasis. In addition, loss of RalA in the metastatic PC3 cell line inhibited bone metastasis but did not affect subcutaneous tumor growth. Loss of Ral appeared to suppress expansive growth of prostate cancer cells in bone, whereas homing and initial colonization were less affected. These data extend our understanding of the functional roles of the Ral pathway and begin to identify signaling pathways relevant for organ-specific metastasis.
