    Increased plasma concentrations of proprotein convertase subtilisin/kexin type 9 or PCSK9, which reduces hepatic uptake of low-density lipoprotein by downregulation of the low-density lipoprotein receptor, have been reported in nephrotic patients and might contribute to hyperlipidemia in nephrotic syndrome. The results of the study by Molina-Jijon et al. found that renal PCSK9 expression was upregulated in the collecting duct of nephrotic patients and animals, suggesting that the kidney might be a major source for plasma PCSK9 in nephrotic syndrome.The mechanisms sustaining a high level of autophagy in podocytes are not well delineated. Seminal studies had unraveled that the polyamine pathway is involved in the regulation of aging and autophagy. Polyamines (e.g., spermine, spermidine, and putrescine) are ubiquitous molecules essential for the physiological processes, including cell growth, development, and differentiation. Liang et al. examined the role of ornithine decarboxylase, and spermidine synthase, and demonstrated that endogenous spermidine is required to maintain intact podocyte autophagy.Peer reporting interventions (i.e., Positive Peer Reporting and tootling) are commonly used peer-mediated interventions in schools. These interventions involve training students to make reports about peers’ prosocial behaviors, whether in oral or written form. Although peer reporting interventions have been included in meta-analyses of group contingencies, this study is the first meta-analytic review of single-case research focusing exclusively on peer reporting interventions. The literature search and application of inclusion criteria yielded 21 studies examining the impact of a peer reporting intervention on student behavior compared to baseline conditions. All studies used single-case experimental designs including at least three demonstrations of an effect and at least three data points per phase. Several aspects of studies, participants, and interventions were coded. Log response ratios and Tau were calculated as effect size estimates. Effect size estimates were synthesized in a multi-level meta-analysis with random effects for (a) studies and (b) cases within studies. Overall results indicated peer reporting interventions had a non-zero and positive impact on student outcomes. This was also true when data were subset by outcome (i.e., disruptive behavior, academically engaged behavior, and social behavior). Results were suggestive of more between- than within-study variability. Moderator analyses were conducted to identify aspects of studies, participants, or peer reporting interventions associated with differential effectiveness. Moderator analyses suggested published studies were associated with higher effect sizes than unpublished studies (i.e., theses/dissertations). This meta-analysis suggests peer reporting interventions are effective in improving student behavior compared to baseline conditions. Implications and directions for future investigation are discussed.The purpose of this study was to support the development and initial validation of the Intervention Selection Profile (ISP)-Skills, a brief 14-item teacher rating scale intended to inform the selection and delivery of instructional interventions at Tier 2. Teacher participants (n = 196) rated five students from their classroom across four measures (total student n = 877). These measures included the ISP-Skills and three criterion tools Social Skills Improvement System (SSIS), Devereux Student Strengths Assessment (DESSA), and Academic Competence Evaluation Scales (ACES). Diagnostic classification modeling (DCM) suggested an expert-created Q-matrix, which specified relations between ISP-Skills items and hypothesized latent attributes, provided good fit to item data. DCM also indicated ISP-Skills items functioned as intended, with the magnitude of item ratings corresponding to the model-implied probability of attribute mastery. DCM was then used to generate skill profiles for each student, which included scores representing the probability of students mastering each of eight skills. Correlational analyses revealed large convergent relations between ISP-Skills probability scores and theoretically-aligned subscales from the criterion measures. buy Vorinostat Discriminant validity was not supported, as ISP-Skills scores were also highly related to all other criterion subscales. Receiver operating characteristic (ROC) curve analyses informed the selection of cut scores from each ISP-Skills scale. Review of classification accuracy statistics associated with these cut scores (e.g., sensitivity and specificity) suggested they reliably differentiated students with below average, average, and above average skills. Implications for practice and directions for future research are discussed, including those related to the examination of ISP-Skills treatment utility.Researchers have become interested in the school climate experiences of Black youth given findings of less positive evaluations of school climate in comparison to their other-race peers. School support for cultural pluralism, also referred to as school support for cultural diversity, has been regarded as one aspect of school climate, but is sometimes distinct from Black youth’s ratings of general perceptions of school climate. This project sought to understand the relationship between Black students’ perceptions of school support for cultural pluralism and perceptions of school climate. Structural equation modeling techniques were used to determine whether previous perceptions of school support for cultural pluralism predicted later perceptions of school climate in a sample of 336 Black adolescents (Mage = 13.74 years). Furthermore, racial identity was explored as the mechanism through which school support for cultural pluralism impacted school climate appraisals, and differences between Black boys (N = 151) and Black girls (N = 185) were tested. Results confirmed that Black youth who rated their school as being supportive of culturally pluralism had more positive ratings of school climate during the following school year after controlling for the previous year’s school climate ratings. However, the mediating role of racial identity differed for Black boys and Black girls, underscoring the need for intersectional research for Black youth and the importance of racial identity. We conclude with a discussion regarding the importance of racial/ethnic identity and pluralism within the school context, as well as, the unique role of school psychologists as preventionists and advocates of change within schools.
