Racial matching and adolescent self-disclosure of substance use and mental health symptoms

Obtaining accurate assessment data from adolescents in treatment aids clinical decision making and facilitates more accurate outcome evaluations. However, findings could be biased due to underreported substance use and mental health symptoms. This article compares self-reports of youth in non-White matched client–assessor dyads and those in nonmatched dyads. There were no differences on self-reported substance use, but matched youth reported significantly fewer attention deficit/hyperactivity disorder symptoms versus the comparison group. One possible reason for these findings is the effect of in-group stereotype threat. Future studies should examine the potential effect that in-group stereotyping and perceived racism have on the therapeutic relationship.     

Genetic variation of 17 autosomal STR loci in the Lahu population from Yunnan and phylogenetic structure exploration among 28 populations

This study evaluated the genetic variation of 17 autosomal short tandem repeat (STR) loci included in the PowerPlex® 18D Kit. Samples of 562 unrelated healthy Lahu individuals living in Yunnan Province in southwestern China were investigated. The data were analyzed to provide information on allele frequencies and other statistical parameters relevant to the forensic population. Of the 17 loci, 16 reached the Hardy–Weinberg equilibrium after Bonferroni correction. A total of 176 alleles were identified in 17 STR loci, and allele frequencies ranged from 0.000 890 to 0.578 292. The combined discrimination power (CPD) and probability of excluding paternity (CPE) of the 17 STR loci were 0.999 999 999 999 999 999 489 and 0.999 998 301 753 122. The genetic relationships among 28 populations were also estimated.     

EARLY EDUCATION AND CHILDREN WITH SPECIAL NEEDS

Changing issues in the field of preschool education will be discussed, set in the context of two of my studies which have been concerned with children with special needs in 'ordinary' preschool education, one 'pre-Warnock' in Scotland, and the other 'post-Warnock' in the West Midlands. The concept of special needs will then be widened to include children for whom English is a second language, and also gifted children. Finally, the discussion is extended to early education rather than preschool education with a discussion of the dangers of treating preschool education in isolation.     

Do ethnicity and gender have an impact on pain thresholds in minor dermatologic procedures?

Background and Objectives: The perception of pain is a personal experience influenced by many factors, including genetic, ethnic and cultural issues. Understanding these perceptions is especially important in dermatologic patients undergoing minor surgical operations and who often differ in their pain response to surgical treatments. Little is known about how these differences affect the perception of experimental pain. The purpose of this study was to determine experimental pain perception differences in three distinct East Asian ethnic populations.
Methods: Pain thresholds were examined with a psychophysical computerized quantitative thermal sensory testing device (TSA 2001) in healthy volunteers recruited from three different Asian ethnic groups. Using the methods of limits, experimental pain perception threshold was measured on the forehead and volar aspect of the forearm in 49 healthy subjects. The measurements were then repeated after skin barrier perturbation with adhesive tape stripping of the stratum corneum. All three ethnic groups were analyzed separately with respect to age, gender educational level and skin type.
Results: A total of 20 Chinese, 14 Malay and 15 Indian subjects completed the study. Thermal pain thresholds were similar in all three ethnic groups before and after tape strippings. No significant differences were noted between genders.
Conclusions: Using quantitative sensory thermal testing, we demonstrated that no significant differences in pain occur between different races and genders.     

Providence School Asthma Partnership: School-based Asthma Program for Inner-City Families

Over 3 years, 972 families participated in an after-school asthma program at their child's school. Parents and children attended concurrent 2¹/₂ -hour workshops. Parents were 74% Latino; 45% non-English speaking, with 77% of children on Medicaid. Asthma symptoms were significantly reduced, from multiple times per week to less than once per week on average. Oral steroid use decreased to one third of baseline use. Hospital days decreased from 11% to 2%; emergency visits decreased 35% to 4%; and school days missed decreased 48% to 20%. This program has now become sustainable with both private and Medicaid insurance coverage.     

恩施土家族人眼的表面形态特征

按随机抽样原则选择湖北恩施土家族人５９８名观测了眼的表面形态。该民族大部分人两眼位置适中，虹膜褐色，眼裂水平，开度中等，无蒙古褶，双睑；多为细窄眼型或中等眼型；眼的各径男大于女，一般存在性别差异；随年龄增加，眼型由中等型向细窄型转化，根据眼外形特征和聚类分析推测，土家人眼属于南、北方民族间的过渡型。     

Ethnic Minorities, Migration and Risk of Undernutrition in Children

Well-controlled, comparative studies suggest that in "food rich" or "resource rich" environments, ethnic minority status is not an independent risk factor for malnutrition. In England, Australia, and the United States, nutrient intake, nutritional status measures and growth are comparable between children of ethnic minorities and non-minority children of similar economic status. Children of recent immigrants are an exception to this generalization, suggesting that recent arrival in a new environment is a risk factor for malnutrition. Family-level studies of intraethnic diversity are required to develop more sensitive and specific profiles of risk factors for malnutrition.
