Introduction: Mentor relationships are important in developing and supporting professional self-efficacy among psychology trainees. Additionally, the rapid diversification of the United States calls for the preparation of clinical neuropsychology trainees to work within a multicultural context. The present study aimed to assess neuropsychology trainees' perceptions of multicultural climate and supervision and if these perceptions differ based on trainee demographics. We also sought to identify aversive experiences of trainees, program strengths or weaknesses, and how programs support trainees., Method: Participants were 310 neuropsychology trainees (Mean age = 30.27, SD  = 5.67) from clinical psychology graduate ( n = 136), pre-doctoral internship ( n = 38), and post-doctoral ( n = 71) programs across the United States and Canada who completed a survey assessing perceptions to multicultural climate and supervision. 64.5% self-identified as women, 60.3% as heterosexual, and 46.1% as non-Hispanic White. 34.5% of trainees reported at least one American Disabilities Act (ADA) recognized disability., Results: Though satisfied with general supervision, trainees reported overall dissatisfaction with multicultural supervision. Satisfaction with multicultural supervision did not differ by demographics. Trainees also reported various aversive experiences with supervisors, clients, and research participants that negatively impacted their training. These experiences were at times due to an aspect of the trainee's multicultural identity, with Black and Hispanic trainees being more likely to report an aversive experience. Trainees reported ways in which they felt unsupported by their programs., Conclusions: Important areas of growth for programs are discussed. Issues raised by neuropsychology trainees overlap to some degree with the experiences of trainees in other fields. Recommendations of approaches that have been successfully adopted in other fields to improve trainee satisfaction are provided. Early identification of needs that go above and beyond clinical training will allow programs to respond promptly, improve trainee satisfaction, and potentially improve the retention of trainees from diverse backgrounds.

Objective: Black American individuals comprise about 13% of the population in the United States (U.S.). It is estimated by 2045, approximately 50% of U.S. residents will belong to an ethnic minority group underscoring the importance of the provision of culturally competent services. The present study provides a critical/systematic review of the literature to examine the representation of Black Americans in recent neuropsychological research in U.S. neuropsychology journals. We examined the representation of U.S. Black American individuals across journals, year of study, and by study sample., Method: We evaluated 1,151 journal articles published in 4 neuropsychology journals published in 2011, 2014, 2017 and 2019. Articles were coded for reporting of age, sex/gender, years of education, ethnicity/race, and if race was a focus of the study. We also recorded sample size and type of sample., Results: Out of the 397 articles meeting inclusion criteria, 37.5% did not report ethnic or racial demographic information. Additionally, 96% of the articles were not racially/ethnically focused. Black participants comprised 10.7% of participants in articles that reported race/ethnicity. The proportion of Black participants increased by 3.7% between 2011 and 2019., Conclusion: Our results demonstrate the underrepresentation of U.S. Black Americans in neuropsychological research over the targeted years. This highlights our shortcomings as a field in demonstrating the importance of including Black Americans in research.

Background: United States Census Bureau projects African Americans (AAs) will be one of the fastest growing populations over the next 30 years. Research suggests they are at higher risk for developing dementia. It is important to know about AA adults' beliefs about, and knowledge of, dementia; and how these beliefs and knowledge impact participation in dementia research., Methods: Four focus groups were completed with 51 older AA adults (76.5% female; mean age=68) in Baton Rouge, Louisiana to examine understanding of dementia and barriers influencing willingness to participate in a clinical trial on dementia risk reduction., Findings: Participants exhibited awareness of several risk and protective factors related to dementia, including family history of dementia, lack of cognitive engagement, and sedentary lifestyles. They were willing to participate in interventions to lower the risk of developing dementia. Barriers to participation included invasive procedures, pharmaceutical interventions, mistrust of investigators, inadequate compensation, and long study duration., Discussion: Given the high relevance of dementia research to older AAs, their knowledge of dementia, and their willingness to participate in dementia research once barriers are addressed, it is imperative to continue to identify and remediate factors contributing to the poor representation of AAs in dementia research., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

Objectives: Projections from the United States Census Bureau suggest that the African American population may be the fastest growing race over the next 30 years and that they may be at the highest risk for developing dementia later in life. Various social factors have been shown to be associated with cognitive function and health outcomes. The present study aims to evaluate the relationship between social engagement and cognitive decline in a cohort of older African American adults., Methods: We utilized multilevel modeling to examine the association between cognitive decline and social engagement in a sample of 617 older African American adults., Results: Social activity was associated with global cognition, perceptual speed, perceptual orientation, and episodic memory over time. Loneliness was associated with better semantic memory performance over time. Perceived discrimination was associated with better semantic memory performance over time. Larger social network was associated with worse perceptual speed scores over time., Conclusions: Although our findings on loneliness and perceived discrimination over time were inconsistent with prior research, our findings on social activity and social network size over time were consistent with past literature and are thought to be due to positive social interactions providing a catalyst for cognitively stimulating activities. These results suggest that interventions designed to preserve cognition in African American older adults should incorporate adequate social activity. Furthermore, to maximize effectiveness, interventions should not necessarily focus on just expanding one's social network., (© 2020 John Wiley & Sons Ltd.)

Dental caries is the most common chronic disease in children and a major public health concern due to its increasing incidence, serious health and social co-morbidities, and socio-demographic disparities in disease burden. We performed the first genome-wide association scan for dental caries to identify associated genetic loci and nominate candidate genes affecting tooth decay in 1305 US children ages 3-12 yrs. Affection status was defined as 1 or more primary teeth with evidence of decay based on intra-oral examination. No associations met strict criteria for genome-wide significance (p < 10E-7); however, several loci (ACTN2, MTR, and EDARADD, MPPED2, and LPO) with plausible biological roles in dental caries exhibited suggestive evidence for association. Analyses stratified by home fluoride level yielded additional suggestive loci, including TFIP11 in the low-fluoride group, and EPHA7 and ZMPSTE24 in the sufficient-fluoride group. Suggestive loci were tested but not significantly replicated in an independent sample (N = 1695, ages 2-7 yrs) after adjustment for multiple comparisons. This study reinforces the complexity of dental caries, suggesting that numerous loci, mostly having small effects, are involved in cariogenesis. Verification/replication of suggestive loci may highlight biological mechanisms and/or pathways leading to a fuller understanding of the genetic risks for dental caries.

The attack on the World Trade Center on 9/11/2001 challenged current approaches to forensic DNA typing methods. The large number of victims and the extreme thermal and physical conditions of the site necessitated special approaches to the DNA-based identification. Because of these and many additional challenges, new procedures were created or modified from routine forensic protocols. This effort facilitated the identification of 1594 of the 2749 victims. In this Policy Forum, the authors, who were were members of the World Trade Center Kinship and Data Analysis Panel, review the lessons of the attack response from the perspective of DNA forensic identification and suggest policies and procedures for future mass disasters or large-scale terrorist attacks.

Susceptibility genes on chromosome 18, and a parent-of-origin effect, have been suggested for bipolar disorder. We analyzed BP data sets provided by the National Institutes of Mental Health and Johns Hopkins University to the Genetic Analysis Workshop 10. Numerous statistical methods were applied to detect association, linkage, and parent-of-origin effects, under alternative diagnostic models. The methods were subsequently compared. Our results suggest that the evidence of linkage of BP to chromosome 18 markers tends to increase, often substantially, as the classification of "affected" individuals broadens. Additionally, a parent-of-origin effect was detected in some of the families.

A statewide survey of nurses in perinatal centers was conducted to assess the prevalence of do-not-resuscitate (DNR) policies in neonatal intensive care units (NICUs) and to examine factors influencing nurses in those centers in their compliance with DNR orders. Three nurses in each of 10 perinatal centers were asked to complete a questionnaire on DNR policies and nurses' compliance and to respond to four hypothetical clinical situations. Eighteen of the 27 responding nurses reported the existence of a DNR policy. Factors affecting compliance with DNR orders were agreement that the infant should not be resuscitated (n = 24) or respect for the parents' wishes (n = 19). Nurses' intention to resuscitate despite a DNR order varied, depending on the description of the infant. Multiple regression analyses showed that subjective norms (beta = .41 to .82) rather than attitudes (beta = .17 to .39) exerted a more powerful influence on nurses' decisions not to resuscitate.
