What is the likelihood that Thoroughbred foals treated for septic arthritis will race?

EQUINE VETERINARY JOURNAL, Issue 5 2004
L. J. SMITH
Summary Reasons for performing study: Septic arthritis is a serious problem in the neonate, with a poor prognosis being reported for recovery. The impact of neonatal septic arthritis on the likelihood that Thoroughbred (TB) foals will start on a racecourse is not known. Hypothesis: The development of septic arthritis in a TB foal significantly reduces the likelihood that it will race when compared to foals from the same dam. Methods: Medical records of 69 foals treated for septic arthritis were reviewed. The dam's foaling records were reviewed and lifetime racing records were then retrieved for both the affected foals and at least one of their siblings (controls). Outcomes that were statistically evaluated included discharge from the hospital and whether the foal eventually raced. Univariate analyses of categorical variables were conducted for each outcome. The number of affected and unaffected foals that raced at least once were compared using regression analysis. Survival analysis was used to compare age at first race between the study and comparison groups. Results: Foals with septic arthritis were less likely to start on a racecourse compared to controls (odds ratio [OR] 0.28; 95% confidence interval [CI] 0.12-0.62, P = 0.001), while those foals that were discharged from the hospital were also less likely to start on a racecourse compared to controls (OR 0.36; CI 0.15,0.83, P = 0.008). The presence of multisystem disease was associated with a decreased likelihood of surviving to be discharged (OR 0.13; 95% CI 0.02-0.90; P = 0.005), but did not affect the likelihood that they would start in at least one race if discharged successfully (OR 0.45; 95% CI 0.04-2.81; P = 0.34) compared to the other foals with septic arthritis. Log-rank comparison of survival curves confirmed that foals discharged following treatment for septic arthritis took significantly longer to start in their first race compared to the sibling population (mean age of study group 1757 days, CI 1604-1909; mean age of sibling group 1273 days, CI 1197-1349; P = 0.0006). Conclusions: The development of septic arthritis in a TB foal significantly reduces the likelihood that it will start on a racecourse when compared to controls. Potential relevance: Accurate figures allowing a realistic assessment of the athletic future of a foal following treatment for septic arthritis are of significance for both owner and treating veterinarian.

Educational Policy, Politics, and Mixed Heritage Students in the United States

JOURNAL OF SOCIAL ISSUES, Issue 1 2009
Kristen A. Renn
This article describes local, state, and federal policies related to collecting, aggregating, and reporting data on student race and ethnicity in U.S. K-12 and postsecondary education. It traces data policy from the 1997 decision by the Office of Management and Budget to change from single-race reporting to a format that permits respondents to choose more than one race, to the October 2007 issuance of final guidance from the Department of Education. Taking a K-20 perspective, I consider how policies for data collection and reporting may affect educational and developmental outcomes for students, as well as local, state, and national education policy environments.

Human DNA sequences: More variation and less race

AMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY, Issue 1 2009
Jeffrey C. Long
Abstract Interest in genetic diversity within and between human populations as a way to answer questions about race has intensified in light of recent advances in genome technology. The purpose of this article is to apply a method of generalized hierarchical modeling to two DNA data sets. The first data set consists of a small sample of individuals (n = 32 total, from eight populations) who have been fully resequenced for 63 loci that encode a total of 38,534 base pairs. The second data set consists of a large sample of individuals (n = 928 total, from 46 populations) who have been genotyped at 580 loci that encode short tandem repeats. The results are clear and somewhat surprising. We see that populations differ in the amount of diversity that they harbor. The pattern of DNA diversity is one of nested subsets, such that the diversity in non-Sub-Saharan African populations is essentially a subset of the diversity found in Sub-Saharan African populations. The actual pattern of DNA diversity creates some unsettling problems for using race as meaningful genetic categories. For example, the pattern of DNA diversity implies that some populations belong to more than one race (e.g., Europeans), whereas other populations do not belong to any race at all (e.g., Sub-Saharan Africans). As Frank Livingstone noted long ago, the Linnean classification system cannot accommodate this pattern because within the system a population cannot belong to more than one named group within a taxonomic level.

When Being Different Is Detrimental: Solo Status and the Performance of Women and Racial Minorities

ANALYSES OF SOCIAL ISSUES & PUBLIC POLICY, Issue 1 2002
Mischa Thompson
Individuals experience solo status when they are the only members of their social category (e.g., gender or race) present in an otherwise homogenous group. Field studies and surveys indicate that members of socially disadvantaged groups, such as women and racial minorities, have more negative experiences as solos than do members of privileged groups, such as Whites and males (Kanter, 1977; Niemann & Dovidio, 1998). In this article, we review research showing that the public performance of women and African-Americans is more debilitated by solo status than that of Whites and males. We also show that this effect is exacerbated when negative stereotypes about the performer's social group seem relevant to their performance, and we discuss the contributing roles of lowered performance expectancies and feelings of group representativeness. We discuss how findings from social psychological research can be applied towards the goal of reducing the decrements typically associated with being the only member, or one of few members, of one's race and/or gender in the environment.
