Children with cancer and their cardiorespiratory fitness and physical function-the long-term effects of a physical activity program during treatment: a multicenter non-randomized controlled trial.

Purpose: We aimed to determine the effects of a classmate-supported, supervised, in-hospital physical activity program during treatment primarily on cardiorespiratory fitness and secondarily on physical function.

Methods: A multicenter non-randomized controlled intervention study including children diagnosed with cancer, 6-18 years at diagnosis treated with chemo-/radiotherapy. The intervention comprised (i) an educational session on cancer in the child's school class; (ii) selection of two "ambassadors"-classmates who were co-admitted, supporting the child's everyday hospital life; and (iii) supervised in-hospital physical activity from diagnosis and throughout intensive treatment.

Metagenomic analyses of a microbial assemblage in a subglacial lake beneath the Vatnajökull ice cap, Iceland.

Skaftárkatlar are two subglacial lakes located beneath the Vatnajökull ice cap in Iceland associated with geothermal and volcanic activity. Previous studies of these lakes with ribosomal gene (16S rDNA) tag sequencing revealed a limited diversity of bacteria adapted to cold, dark, and nutrient-poor waters. In this study, we present analyses of metagenomes from the lake which give new insights into its microbial ecology.

Seasonal variation in the correlation between beach wrack and marine litter on a sandy beach in West Iceland.

Coastal plastic pollution is a global problem, it affects local ecosystems, and can have economic and social implications. Plastic pollution is pervasive at high latitudes but there is a lack of data on the spatial and temporal amount of marine litter entering coastal systems. In this study, a seasonal accumulation survey of anthropogenic debris and beach wrack was conducted for the first time in Iceland.

Childhood cancer survivors' and their parents' experiences with participation in a physical and social intervention during cancer treatment: A RESPECT study.

Aims: This study explores experiences of childhood cancer survivors and their parents with a combined physical and social activity intervention during treatment, including how the survivors and their parents perceive physical activity post-treatment.

Design: A process evaluation using semi-structured interviews.

Methods: Using a criterion-sampling strategy, 18 Danish childhood cancer survivors (aged 11-18 years) and their parents were interviewed from September 2019 through May 2020.

Medication use in populations exposed to the 2010 Eyjafjallajökull eruption: an interrupted time series analysis.

Objectives: To assess the trends in medication use indicative of physical and psychological morbidity following the 2010 volcanic eruption in Eyjafjallajökull immediately after and during a 3-year period following the eruption.

Design: Population-based register study.

Setting: Eyjafjallajökull eruption in Iceland, 2007-2013.
