RESUMO

This article presents a short-term longitudinal study examining bidirectional associations between academic achievement and positive peer regard among Asian American and Latinx adolescents. Specifically, our investigation distinguished between positive peer regard within and across different ethnic groups in a diverse school setting. Three hundred and thirty-five middle school students (52.8% girls; 65% Asian American, 35% Latinx; assessment at the first time point Mage = 12.27 years, SD = 0.71) were followed across two consecutive school years. Participants completed a peer-nomination inventory assessing multiple dimensions of positive peer regard (i.e., reciprocal friendship, social acceptance, and respect), and grades were obtained from school records. Academic achievement was predictive of prospective positive peer regard received from same-ethnic peers only for Asian American adolescents. In contrast, academic achievement predicted prospective positive peer regard received from cross-ethnic peers only for Latinx adolescents. These results suggest that academic achievement was linked to social gains with peers from different ethnic backgrounds for Asian American and Latinx students. The findings underscore the importance of disentangling the sources of positive peer regard in multiethnic school environments. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

RESUMO

PURPOSE: Clinical genomic sequencing of pediatric tumors is increasingly uncovering pathogenic variants in adult-onset cancer predisposition genes (aoCPG). Nevertheless, it remains poorly understood how often aoCPG variants are of germline origin and whether they influence tumor molecular profiles and/or clinical care. In this study, we examined the prevalence, spectrum, and impacts of aoCPG variants on tumor genomic features and patient management at our institution. EXPERIMENTAL DESIGN: This is a retrospective study of 1,018 children with cancer who underwent clinical genomic sequencing of their tumors. Tumor genomic data were queried for pathogenic variants affecting 24 preselected aoCPGs. Available tumor whole-genome sequencing (WGS) data were evaluated for second hit mutations, loss of heterozygosity (LOH), DNA mutational signatures, and homologous recombination deficiency (HRD). Patients whose tumors harbored one or more pathogenic aoCPG variants underwent subsequent germline testing based on hereditary cancer evaluation and family or provider preference. RESULTS: Thirty-three patients (3%) had tumors harboring pathogenic variants affecting one or more aoCPGs. Among 21 tumors with sufficient WGS sequencing data, six (29%) harbored a second hit or LOH affecting the remaining aoCPG allele with four of these six tumors (67%) also exhibiting a DNA mutational signature consistent with the altered aoCPG. Two additional tumors demonstrated HRD, of uncertain relation to the identified aoCPG variant. Twenty-one of 26 patients (81%) completing germline testing were positive for the aoCPG variant in the germline. All germline-positive patients were counseled regarding future cancer risks, surveillance, and risk-reducing measures. No patients had immediate cancer therapy changed due to aoCPG data. CONCLUSIONS: AoCPG variants are rare in pediatric tumors; however, many originate in the germline. Almost one third of tumor aoCPG variants examined exhibited a second hit and/or conferred an abnormal DNA mutational profile suggesting a role in tumor formation. aoCPG information aids in cancer risk prediction but is not commonly used to alter the treatment of pediatric cancers.

RESUMO

This paper examines the moderating role of problem-talk partnerships with peers who are rejected, victimized, or unpopular on links between self-perceived victimization by peers and depressive symptoms. Problem-talk partnerships are friendships that involve frequent discussion of problems and personal struggles. 267 adolescents (152 girls; mean age of 14.4 years) participated in a short-term prospective study with identical measures administered in two annual waves. The adolescents completed a battery of self-report questionnaires assessing peer victimization and depression. They also completed a peer nomination inventory and identified friends with whom they frequently discuss problems. High levels of peer nominated victimization, social rejection, and unpopularity among problem-talk partners were linked to elevated associations between self-reported victimization and depressive symptoms. The effects for unpopularity levels among problem-talk partners were moderated by gender. Compared to boys, girls' adjustment was more strongly influenced by unpopularity among problem-talk partners. Conversely, friendships with peers who were not problem-talk partners did not have a consistent moderating role. The full pattern of findings highlights the need to consider the social adjustment of dyadic partners when examining the psychosocial impact of perceived victimization.

RESUMO

Genomic studies of pediatric cancer have primarily focused on specific tumor types or high-risk disease. Here, we used a three-platform sequencing approach, including whole-genome sequencing (WGS), whole-exome sequencing (WES), and RNA sequencing (RNA-seq), to examine tumor and germline genomes from 309 prospectively identified children with newly diagnosed (85%) or relapsed/refractory (15%) cancers, unselected for tumor type. Eighty-six percent of patients harbored diagnostic (53%), prognostic (57%), therapeutically relevant (25%), and/or cancer-predisposing (18%) variants. Inclusion of WGS enabled detection of activating gene fusions and enhancer hijacks (36% and 8% of tumors, respectively), small intragenic deletions (15% of tumors), and mutational signatures revealing of pathogenic variant effects. Evaluation of paired tumor-normal data revealed relevance to tumor development for 55% of pathogenic germline variants. This study demonstrates the power of a three-platform approach that incorporates WGS to interrogate and interpret the full range of genomic variants across newly diagnosed as well as relapsed/refractory pediatric cancers. SIGNIFICANCE: Pediatric cancers are driven by diverse genomic lesions, and sequencing has proven useful in evaluating high-risk and relapsed/refractory cases. We show that combined WGS, WES, and RNA-seq of tumor and paired normal tissues enables identification and characterization of genetic drivers across the full spectrum of pediatric cancers. This article is highlighted in the In This Issue feature, p. 2945.

RESUMO

Radiation therapy plays an important role in the multidisciplinary management of breast cancer. Recent years have seen improvements in breast cancer survival and a greater appreciation of potential long-term morbidity associated with the dose and volume of irradiated organs. Proton therapy reduces the dose to nontarget structures while optimizing target coverage. However, there remain additional financial costs associated with proton therapy, despite reductions over time, and studies have yet to demonstrate that protons improve upon the treatment outcomes achieved with photon radiation therapy. There remains considerable heterogeneity in proton patient selection and techniques, and the rapid technological advances in the field have the potential to affect evidence evaluation, given the long latency period for breast cancer radiation therapy recurrence and late effects. In this consensus statement, we assess the data available to the radiation oncology community of proton therapy for breast cancer, provide expert consensus recommendations on indications and technique, and highlight ongoing trials' cost-effectiveness analyses and key areas for future research.
