MBCL-07. NON-METASTATIC MEDULLOBLASTOMA OF EARLY CHILDHOOD: RESULTS FROM THE PROSPECTIVE CLINICAL TRIAL HIT-2000 AND AN EXTENDED VALIDATION COHORT
2020
Abstract OBJECTIVE To avoid craniospinal irradiation (CSI) in children younger than four years with non-metastatic medulloblastoma by chemotherapy, intraventricular methotrexate and risk-adapted local radiotherapy. PATIENTS AND METHODS Eighty-seven patients received systemic chemotherapy and intraventricular methotrexate. Until 2006, CSI was reserved for non-response or progression. After 2006, local radiotherapy was introduced for non-responders or classic (CMB), anaplastic or large-cell medulloblastoma (LCA). Infantile SHH-activated medulloblastomas (SHH_INF) were subdivided by DNA-methylation profiling. Survival in SHH_INF subtypes were also assessed in a validation cohort (n=71). RESULT…

IMPLICIT THEORIES OF INTELLIGENCE AND ACADEMIC ACHIEVEMENT: REVIEW OF TWO STUDIES IN LATVIA
2020
Growth mindset has become popular in the field of psychology and education all around the world. In the Baltic States this concept is relatively new. This research compiles results of two different studies that, for the first time in the Baltic States, analyse the concept of “implicit theories of intelligence” (ITI) and its factors – growth and fixed mindset, and investigate the relations between ITI and academic achievement of students. Data of two different samples of secondary school adolescents is used. Sample 1 consisted of students (N1=258) aged between 14 and 18, 134 females (M=15.13; SD=1.29) and 124 males (M=15.40; SD=1.20) studying in 7th-12th grade in two Latvian schools. Sample …
Human Immunodeficiency Virus Infection and Diverse Physical Health Outcomes: An Umbrella Review of Meta-analyses of Observational Studies.
2019
Abstract Background Our aim was to assess both the credibility and strength of evidence arising from systematic reviews with meta-analyses of observational studies and physical health outcomes associated with human immunodeficiency virus (HIV) but not acquired immunodeficiency syndrome. Methods We performed an umbrella review of observational studies. Evidence was graded as convincing, highly suggestive, suggestive, weak, or nonsignificant. Results From 3413 studies returned, 20 were included, covering 55 health outcomes. Median number of participants was 18 743 (range 403–225 000 000). Overall, 45 (81.8%) of the 55 unique outcomes reported nominally significant summary results (P < .05). O…
Healthy Lifestyle, Well-being, Physical Activity, Sport, and Scholastic/academic Performance: Interactions and Connections
2019
The physical activity and sport are key elements for a healthy lifestyle. However, a little-investigated element is the presence of a possible relationship between school or academic performance and the participation in physical activity and sport in groups of preadolescents and adolescents. In order to clarify the complex relationship between mind and body in preadolescence and adolescence, the present discussion investigates the causal and direct relationship between sport activity and performance; and describes how this relationship can be mediated by the sense of self-esteem and self-efficacy; and investigates the relationship between group sports practice and school or academic perform…
Peer ethnicity and achievement: a meta-analysis into the compositional effect
2010
This study reports a meta-analysis on the effects of ethnic minority share in school on achievement test scores. Best evidence from the studies that have appeared thus far on this topic shows that these compositional effects appear small in general, but may be larger when the ethnic minority group is African Americans in the USA, than when the minority group consists of immigrants. A high share of students from an ethnic minority group seems to affect the achievement from students belonging to the same ethnic group more, than the achievement of students belonging to the ethnic majority or to other ethnic minority groups. Effects of the share of immigrants on test scores of ethnic majority s…
Effects of Mobility Programmes on University Students' Academic Performance
2018
The number of students participating in mobility programmes has increased enormously over the years. The reasons are diverse and may range from personal growth to better employability prospects, together with improvement in foreign language skills and intercultural awareness. Mobility programmes receive generous funding from the European Commission, therefore their outcomes should be measured and evaluated. This paper focuses on a specific one: the academic effects of mobility programmes. We analyse whether there is an improvement in the academic performance of the students who participate in mobility programmes and, if this is the case, whether it is sustained over time. We use a broad dat…

Correction to ‘Secondary structure determination of conserved SARS-CoV-2 RNA elements by NMR spectroscopy’
2021
The current pandemic situation caused by the Betacoronavirus SARS-CoV-2 (SCoV2) highlights the need for coordinated research to combat COVID-19. A particularly important aspect is the development of medication. In addition to viral proteins, structured RNA elements represent a potent alternative as drug targets. The search for drugs that target RNA requires their high-resolution structural characterization. Using nuclear magnetic resonance (NMR) spectroscopy, a worldwide consortium of NMR researchers aims to characterize potential RNA drug targets of SCoV2. Here, we report the characterization of 15 conserved RNA elements located at the 5' end, the ribosomal frameshift segment and the 3'-un…
