ABSTRACT
OBJECTIVES: Few studies to date have examined the utilization of complementary and alternative medicine (CAM) in a local, ethnically diverse population in the United States (U.S.). Fewer have addressed the differences in their use based on inclusion or exclusion of prayer as a modality. Variable definitions of CAM are known to affect public health surveillance (i.e., continuous, systematic data collection, analysis, and interpretation) or benchmarking (i.e., identifying and comparing key indicators of health to inform community planning) related to this non-mainstream collection of health and wellness therapies. The present study sought to better understand how including or excluding prayer could affect reporting of CAM use among residents of a large, urban U.S. jurisdiction. DESIGN: Using population-weighted data from a cross-sectional Internet panel survey collected as part of a larger countywide population health survey, the study compared use of CAM based on whether prayer or no prayer was included in its definition. Patterns of CAM use by socio-demographic characteristics were described for the two operationalized definitions. Multivariable binomial regression analyses were performed to control for gender, age, race/ethnicity, education, employment, income, and health insurance status. One of the analyses explored the associations between CAM use and racial/ethnic characteristics in the study sample. SETTING: Los Angeles County, California. SUBJECTS: A socio-demographically diverse sample of Los Angeles County residents. OUTCOME MEASURES: CAM use (with prayer) and CAM use (excluding prayer). RESULTS: Blacks were among the highest users of CAM when compared to Whites, especially when prayer was included as a CAM modality. Regardless of prayer inclusion, being a woman predicted higher use of CAM. CONCLUSIONS: How CAM is defined matters in gauging the utilization of this non-mainstream collection of therapies. Given that surveillance and/or benchmarking data are often used to inform resource allocation and planning decisions, results from the present study suggest that when prayer is included as part of the CAM definition, utilization/volume estimates of its use increased correspondingly, especially among non-White residents of the region.
ABSTRACT
BACKGROUND: Agarwood, a heartwood derived from Aquilaria trees, is a valuable commodity that has seen prevalent use among many cultures. In particular, it is widely used in herbal medicine and many compounds in agarwood are known to exhibit medicinal properties. Although there exists much research into medicinal herbs and extraction of high value compounds, few have focused on increasing the quantity of target compounds through stimulation of its related pathways in this species. RESULTS: In this study, we observed that cucurbitacin yield can be increased through the use of different light conditions to stimulate related pathways and conducted three types of high-throughput sequencing experiments in order to study the effect of light conditions on secondary metabolism in agarwood. We constructed genome-wide profiles of RNA expression, small RNA, and DNA methylation under red light and far-red light conditions. With these profiles, we identified a set of small RNA which potentially regulates gene expression via the RNA-directed DNA methylation pathway. CONCLUSIONS: We demonstrate that light conditions can be used to stimulate pathways related to secondary metabolism, increasing the yield of cucurbitacins. The genome-wide expression and methylation profiles from our study provide insight into the effect of light on gene expression for secondary metabolism in agarwood and provide compelling new candidates towards the study of functional secondary metabolic components.

BACKGROUND: Agarwood is derived from Aquilaria trees, the trade of which has come under strict control with a listing in Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora. Many secondary metabolites of agarwood are known to have medicinal value to humans, including compounds that have been shown to elicit sedative effects and exhibit anti-cancer properties. However, little is known about the genome, transcriptome, and the biosynthetic pathways responsible for producing such secondary metabolites in agarwood. RESULTS: In this study, we present a draft genome and a putative pathway for cucurbitacin E and I, compounds with known medicinal value, from in vitro Aquilaria agallocha agarwood. DNA and RNA data are utilized to annotate many genes and protein functions in the draft genome. The expression changes for cucurbitacin E and I are shown to be consistent with known responses of A. agallocha to biotic stress and a set of homologous genes in Arabidopsis thaliana related to cucurbitacin bio-synthesis is presented and validated through qRT-PCR. CONCLUSIONS: This study is the first attempt to identify cucurbitacin E and I from in vitro agarwood and the first draft genome for any species of Aquilaria. The results of this study will aid in future investigations of secondary metabolite pathways in Aquilaria and other non-model medicinal plants.

Introduction. International comparative research on traditional medicine (TM) offers a useful method for examining differences in patient characteristics and can provide insight into: (i) more universal characteristics which may cross cultures and international borders; (ii) unique characteristics influenced by regional/national factors; and (iii) cultural values of immigrant populations. To explore these issues TM patients from the United States and China were compared. Methods. Data collection took place at two TM college clinics. A convenience sample of 128 patients in China and 127 patients in the United States completed a 28-item questionnaire. Results. There was a marked similarity between the two patient groups in terms of the biological characteristics of age and gender. Musculoskeletal issues were the most common presenting complaints in the United States; while in China TM was used for a more diverse array of conditions. The majority of patients in both countries had initially used allopathic medicine (AM); significantly, more of the United States respondents stopped allopathic treatment after beginning traditional treatment. In comparing the two countries, patients in China were significantly more satisfied with AM and American patients significantly more satisfied with TM. In comparing the two medicines, the patient samples in both countries were significantly more satisfied with TM than AM. Discussion. Although treatment often originated with allopathic providers, many patients sought alternatives presumably to find the best solution to their problems. This tendency toward self-assignment suggests that a pluralistic healthcare system may provide the greatest satisfaction resulting from personal choice and improved outcomes.
ABSTRACT
The Licensed Acupuncture Collaborative Study, a job analysis of licensed acupuncturists in California, provides a model for building community-research partnerships between university researchers and communities of non-physician clinicians. The study design used a project-management approach based on the core principles of community-based participatory research: 1) mobilizing shared expertise and resources to address issues of concern; 2) sharing power in the decision-making process; and 3) promoting mutual ownerships of resources and products derived from the collaboration. A project infrastructure involving the sharing of study responsibilities across university researchers, individual acupuncturists, and state community organizations was developed and cultivated over a three-year project period. Essential factors in the success of this project included shared objectives, addressing the concerns about collaboration among academic and community partners, inclusion of nontraditional viewpoints about healthcare policy, and participation by the acupuncturist community in performing the research. These activities helped to overcome mistrust and perceived power differences between researchers and the acupuncturist community.
