Grandparents Raising Grandchildren: What Have We Learned Over the Past Decade?

Abstract: Background and objectives In this manuscript, we update the literature over the last decade in addressing several new content areas that have emerged in the grandfamilies literature, along with issues that are still important to understanding grandparents raising their grandchildren today. Research design and methods The social science and gerontological literature since 2004 was accessed, reviewed, organized topically, and integrated, based upon an exhaustive PsychINFO literature search. Results Our review indicates an ongoing and/or growing emphasis on (a) the strengths of grandparent raising grandchildren, (b) diversity among grandfamilies along a number of parameters, (c) the social-interpersonal, cultural, and policy-related contexts of grandfamilies, (d) process-focused research, (e) parenting, parenting skills, and family relationships, (f) grandparent psychological distress, (g) targets for and the efficacy of interventions with grandfamilies, and (h) methodological issues relevant to the study of grandfamilies. Implications We discuss the implications of our findings in terms of more completely understanding grandfamilies along a number of parameters, as well as presenting specific recommendations for future research and practice.

A Blood-Based Screening Tool for Alzheimer's Disease That Spans Serum and Plasma: Findings from TARC and ADNI

Abstract: Context There is no rapid and cost effective tool that can be implemented as a front-line screening tool for Alzheimer's disease (AD) at the population level. Objective To generate and cross-validate a blood-based screener for AD that yields acceptable accuracy across both serum and plasma. Design, setting, participants Analysis of serum biomarker proteins were conducted on 197 Alzheimer's disease (AD) participants and 199 control participants from the Texas Alzheimer's Research Consortium (TARC) with further analysis conducted on plasma proteins from 112 AD and 52 control participants from the Alzheimer's Disease Neuroimaging Initiative (ADNI). The full algorithm was derived from a biomarker risk score, clinical lab (glucose, triglycerides, total cholesterol, homocysteine), and demographic (age, gender, education, APOE*E4 status) data. Major outcome measures Alzheimer's disease. Results 11 proteins met our criteria and were utilized for the biomarker risk score. The random forest (RF) biomarker risk score from the TARC serum samples (training set) yielded adequate accuracy in the ADNI plasma sample (training set) (AUC = 0.70, sensitivity (SN) = 0.54 and specificity (SP) = 0.78), which was below that obtained from ADNI cerebral spinal fluid (CSF) analyses (t-tau/Aβ ratio AUC = 0.92). However, the full algorithm yielded excellent accuracy (AUC = 0.88, SN = 0.75, and SP = 0.91). The likelihood ratio of having AD based on a positive test finding (LR+) = 7.03 (SE = 1.17; 95% CI = 4.49-14.47), the likelihood ratio of not having AD based on the algorithm (LR-) = 3.55 (SE = 1.15; 2.22-5.71), and the odds ratio of AD were calculated in the ADNI cohort (OR) = 28.70 (1.55; 95% CI = 11.86-69.47). Conclusions It is possible to create a blood-based screening algorithm that works across both serum and plasma that provides a comparable screening accuracy to that obtained from CSF analyses.

Cultural humility and racial microaggressions in counseling.

Abstract: Racial microaggressions may contribute to poor counseling outcomes in racial/ethnic minority clients. The present study examined the occurrence of racial microaggressions in counseling using a large and diverse sample and explored the association between perceived cultural humility of the counselor and racial microaggressions. Racial/ethnic minority participants (N = 2,212) answered questions about the frequency and impact of racial microaggressions in counseling and the characteristics of their counselor. The majority of clients (81%) reported experiencing at least 1 racial microaggression in counseling. Participants most commonly reported racial microaggressions involving denial or lack of awareness of stereotypes and bias and avoidance of discussing cultural issues. There were few differences in racial microaggression frequency or impact based on client race/ethnicity and counselor race/ethnicity. Racially matched clients viewed racial microaggressions as more impactful than did clients who were not racially matched. Client-perceived cultural humility of the counselor was associated with fewer microaggressions experienced in counseling. We conclude by discussing limitations, areas for future research, and implications for counseling.
