  • The influence of physical activity on sleep quality in people living with HIV: a scoping review
    Publication . Cordeiro, Jéssica Fernanda Correa; Anjos, Jeferson Roberto Collevatti dos; Bohn, Lucimere; Bilhadori, Joana; Moraes, Chimenny Auluã Lascas Cardoso de; Andaki, Allyne; Mendes, Edmar Lacerda; Mota, Jorge; Lopes Machado, Dalmo Roberto; Correia, Igor Massari; Santos, André Pereira dos
    Objective: To map the evidence on the effects of physical activity on sleep quality in people living with human immunodeficiency virus (PLHIV). Methods: A scoping review was conducted using PubMed, EMBASE, LILACS, Scopus, Web of Science, EBSCO Sport Discus/CINAHL, and Biblioteca Virtual em Saúde. Additionally, Google Scholar and OpenGrey servers were checked. There were no language or publication year restrictions for the search. Primary studies that evaluated the relationship between physical activity and sleep quality in PLHIV were included. Two researchers performed the analysis and selection of studies independently, following established criteria. Results: Nine studies were included, covering experimental, cross-sectional, and cohort studies. The results suggest that physical activity is associated with reduced sleep latency, longer sleep duration, and overall improvements in sleep efficiency and subjective perception of sleep quality. These results indicate that exercise-based interventions can be incorporated as complementary strategies to improve sleep in this population. However, methodological variability limits the generalization of the results. Future studies should focus on longitudinal designs and standardized assessment methods. Conclusion: Adequate physical activity levels appear to positively influence sleep quality in PLHIV.

  • Illuminating deep-sea considerations and experimental approaches for mCDR proposals
    Publication . Gallo, Natalya D.; Metaxas, Anna; Lidström, Susanna; Hetherington, Elizabeth; Alfaro-Lucas, Joan M.; Amon, Diva; Barry, James; Bax, Narissa; Boyd, Philip W.; Colaço, Ana; Elegbede, Isa; Escobar-Briones, Elva; Halfter, Svenja; Hilario, Ana; Hilmi, Nathalie; Huffard, Christine L.; Iglesias-Rodriguez, M Debora; Levin, Lisa A; McCauley, Douglas J; Mestre, Nélia; Mwangi, Pauline Nyambura; Palacios-Abrantes, Juliano; Rangani, Eesha; Thurber, Andrew R.; Yasuhara, Moriaki
    As society recognizes the urgency of reducing atmospheric CO2 levels, industries and nations are increasingly considering marine carbon dioxide removal (mCDR) in their climate mitigation portfolios. The deep sea (defined as depths below 200 m) is the storage site for removed carbon for most mCDR technologies [1, 2] because, here, carbon is out of contact with the atmosphere on societally relevant timescales (>100 years). However, the deep sea is often treated as a ‘black box’ without sufficient consideration given to deep-sea ecological processes and ecosystem services that may be impacted by mCDR activities (e.g. [2, 3]). The often held ‘out of sight, out of mind’ relationship with the deep sea has previously been used to justify disposal of radioactive, military, and chemical waste in the deep sea [4]. These activities were assumed harmless due to the large and sparsely inhabited nature of the deep sea, and expectations that waste would be permanently removed and that negative impacts would remain in the deep sea and not impact coastal areas or socioeconomic activities.
