Recruitment of ethnic minority patients to a cardiac rehabilitation trial: The Birmingham Rehabilitation Uptake Maximisation (BRUM) study [ISRCTN72884263]

Background: Concerns have been raised about low participation rates of people from minority ethnic groups in clinical trials. However, the evidence is unclear as many studies do not report the ethnicity of participants and there is insufficient information about the reasons for ineligibility by ethnic group. Where there are data, there remains the key question as to whether ethnic minorities more likely to be ineligible (e.g. due to language) or decline to participate. We have addressed these questions in relation to the Birmingham Rehabilitation Uptake Maximisation (BRUM) study, a randomized controlled trial (RCT) comparing a home-based with a hospital-based cardiac rehabilitation programme in a multi-ethnic population in the UK. Methods: Analysis of the ethnicity, age and sex of presenting and recruited subjects for a trial of cardiac rehabilitation in the West-Midlands, UK. Participants: 1997 patients presenting post-myocardial infarction, percutaneous transluminal coronary angioplasty or coronary artery bypass graft surgery. Data collected: exclusion rates, reasons for exclusion and reasons for declining to participate in the trial by ethnic group. Results: Significantly more patients of South Asian ethnicity were excluded (52% of 'South Asian' v 36% 'White European' and 36% 'Other', p < 0.001). This difference in eligibility was primarily due to exclusion on the basis of language (i.e. the inability to speak English or Punjabi). Of those eligible, similar proportions were recruited from the different ethnic groups (white, South Asian and other). There was a marked difference in eligibility between people of Indian, Pakistani or Bangladeshi origin

Meta-analysis of genome-wide association studies of asthma in ethnically diverse North American populations.

Asthma is a common disease with a complex risk architecture including both genetic and environmental factors. We performed a meta-analysis of North American genome-wide association studies of asthma in 5,416 individuals with asthma (cases) including individuals of European American, African American or African Caribbean, and Latino ancestry, with replication in an additional 12,649 individuals from the same ethnic groups. We identified five susceptibility loci. Four were at previously reported loci on 17q21, near IL1RL1, TSLP and IL33, but we report for the first time, to our knowledge, that these loci are associated with asthma risk in three ethnic groups. In addition, we identified a new asthma susceptibility locus at PYHIN1, with the association being specific to individuals of African descent (P = 3.9 × 10(-9)). These results suggest that some asthma susceptibility loci are robust to differences in ancestry when sufficiently large samples sizes are investigated, and that ancestry-specific associations also contribute to the complex genetic architecture of asthma

Constitutional Law: A Contemporary Approach

The third edition of the casebook, which is suitable either for a one- or two-semester course, strives to make constitutional law easily teachable and readily accessible for students. The authors have selected the cases very carefully and provided extensive excerpts of the opinions so that students get a good sense of the Court\u27s reasoning. Text boxes call the students\u27 attention to important aspects of each opinion, and the book is filled with introductions, points for discussion, hypotheticals, and executive summaries. The authors present a diversity of views on every subject, and, reflecting some of their own disagreements, the authors have written point-counterpoint discussions on many disputed questions

The Portland region: Where city and suburbs talk to each other ... and sometimes agree

Portland, OR, is often cited as an example of successful regional governance and planning. The metropolitan area appears to match many of the precepts of the popular compact city model of urban growth and to demonstrate the capacity of local and state government to shape growing metropolitan regions. Given this reputation, it is important to evaluate the relevance of the Portland experience for other communities, distinguishing unique local circumstances form generalizable characteristics. This analysis explores the spatial character of metropolitan Portland in the 1990s, summarizes the politics of regional planning, examines weaknesses in the Portland approach, and offers suggestions for other metropolitan areas. The study finds that many of Portland\u27s accomplishments center on urban design, but that the region\u27s most distinguishing characteristics is its attention to political process. The discussion concludes with suggestions about the value of extensive civic discourse,incremental policy making, and institution building
