Burnout is understood to have many adverse consequences for students. However, several equivocal findings in the literature mean that it is currently unclear to what extent burnout affects academic achievement. To address this lack of clarity, the aim of the present study was to provide a first meta-analysis of the relationship between burnout and academic achievement. A literature search returned 29 studies (N = 109,396) and 89 effect sizes. Robust variance meta-analyses indicated that total burnout had a significant negative relationship with academic achievement (rc+ = − .24). A similar pattern of relationships was found for each of the three symptoms of burnout (exhaustion [rc+ = − .15], cynicism [rc+ = − .24], and reduced efficacy [rc+ = − .39]). There was some evidence that the instrument used to measure burnout moderated the relationship between reduced efficacy and achievement. Taken together, the findings suggest that burnout leads to worse academic achievement in school, college, and university.

Antecedents of academic performance of university students: academic engagement and psychological capital resources

The agri-food industry annually produces huge amounts of crops residues and wastes, the suitable management of these products is important to increase the sustainability of agro-industrial production by optimizing the entire value chain. This is also in line with the driving principles of the circular economy, according to which residues can become feedstocks for novel processes. Oleaginous yeasts represent a versatile tool to produce biobased chemicals and intermediates. They are flexible microbial factories able to grow on different side-stream carbon sources such as those deriving from agri-food wastes, and this characteristic makes them excellent candidates for integrated biorefinery processes through the production of microbial lipids, known as single cell oils (SCOs), for different applications. This review aims to present an extensive overview of research progress on the production and use of oleaginous yeasts and present discussions on the current bottlenecks and perspectives of their exploitation in different sectors, such as foods, biofuels and fine chemicals.

Oleaginous Yeasts as Cell Factories for the Sustainable Production of Microbial Lipids by the Valorization of Agri-Food Wastes

It has been suggested that both performance and academic well-being play a role in adolescent students' educational attainment and school dropout. In this study, we therefore examined, first, what kinds of academic well-being (i.e., school burnout, schoolwork engagement, and mathematics self-concept) and mathematics performance profiles can be identified among lower secondary school students (Ngrade 7 = 583, Ngrade 9 = 497); second, how stable these profiles are across one school year during the seventh and ninth grades; and, third, how students with different academic well-being and mathematics performance profiles differ with respect to their educational aspirations. By means of latent profile analyses, three groups of students in seventh grade: thriving (34%), average (51%), and negative academic well-being (15%) and four groups of students in ninth grade: thriving (25%), average (50%), negative academic well-being (18%), and low-performing (7%) with distinct well-being and mathematics performance profiles were identified. Configural frequency analyses revealed that the profiles were relatively stable across one school year; 60% of the students displayed identical profiles over time. The thriving students reported the highest educational aspirations compared to the other groups. In addition, the low-performing students in the ninth grade had the lowest educational aspirations just before the transition to upper secondary school. Practical implications as well as directions for future research are discussed.

Over the last years oleaginous yeasts have been studied for several energetic, oleochemical, medical and pharmaceutical purposes. However, only a small number of yeasts are known and have been deeply exploited. The search for new isolates with high oleaginous capacity becomes imperative, as well as the use of alternative and ecological carbon sources for yeast growth. In the present study a high-throughput screening comprising 366 distinct yeast isolates was performed by applying an optimised protocol based on two approaches: (I) yeast cultivation on solid medium using acetic acid as carbon source, (II) neutral lipid estimation by fluorimetry using the lipophilic dye Nile red. Results showed that, with the proposed methodology, the oleaginous potential of yeasts with broad taxonomic diversity and variety of growth characteristics was discriminated. Furthermore, this work clearly demonstrated the association of the oleaginous yeast character to the strain level, contrarily to the species-level linkage, as usually stated.

Low levels of education and dropping out of school are associated with criminal involvement. The Portuguese prison system, similar to other prison systems (e.g. England), offers prison-based educational programmes so inmates can complete compulsory education. However, the completion rate of these educational programmes is low, and the dropout rate is high. Deepening our understanding of how inmates conceptualise learning and how they engage in learning will improve the quality of the prison-based educational services and promote school enrolment. Data from a phenomenographic study of 30 Portuguese inmate students, ranging from 20 to 58 years of age, revealed an understanding of learning focused on the instrumental role of knowledge and its application in the short-term (e.g. learning how to read) and on integration in the prison system (e.g. learning how to play draughts to fit in the yard). Moreover, a broader understanding of learning that reflected particular forms of learning favoured within the prison context also emerged in the discourse. For example, learning was described as an opportunity to reflect upon their previous offence and behaviours and on the need to avoid violence. Participants also stressed the importance of setting an academic example for their children by engaging actively in learning and the significance of occupying one's time in prison in a positive and beneficial manner. Findings allow a first approach to prison students' involvement in school learning by listening to the inmates' opinions and thoughts, and they offer promising suggestions to improve the organisation of prison-based educational programmes.

To report a case of vulvar familial benign pemphigus, or Hailey–Hailey disease, treated successfully with low-dose naltrexone and to review the current literature. We report a case of a 71-year-old white woman with vulvar Hailey–Hailey disease recalcitrant to topical corticosteroids. After treatment with low-dose naltrexone, 3 mg nightly was initiated, the lesions began to heal and 5 months later her skin showed no lesions. A literature review on the use of low-dose naltrexone for Hailey–Hailey disease was performed. We searched the PubMed/MEDLINE databases for previous case reports using the key words ‘‘Pemphigus, Benign Familial’’ and ‘‘naltrexone”. We found 35 more cases of Hailey–Hailey disease treated with naltrexone, showing promising results, reported until January 2020, with no major adverse effects. Low-dose naltrexone may represent a cost-effective and successful treatment modality in nongeneralized Hailey–Hailey disease without serious adverse effects. Future prospective studies are needed to investigate this interesting therapeutic option.
