"A sincere 'how are you?' is already a sign of acknowledgement that you're there too." - Interview study on the support needs of adolescents and young adults (AYAs) living with a parent with cancer.

Purpose: Parental cancer brings changes and challenges which affect the whole family. Evidence shows heightened psychosocial risk among the offspring. Research among adolescents and young adults (AYAs) facing parental cancer has mainly focused on these psychosocial problems.

Envisaging a global infrastructure to exploit the potential of digitised collections.

Tens of millions of images from biological collections have become available online over the last two decades. In parallel, there has been a dramatic increase in the capabilities of image analysis technologies, especially those involving machine learning and computer vision. While image analysis has become mainstream in consumer applications, it is still used only on an artisanal basis in the biological collections community, largely because the image corpora are dispersed.

School-based Psychosocial Interventions' Effectiveness in Strengthening Refugee and Migrant Adolescents' Mental Health, Resilience, and Social Relations: A Four-country Cluster Randomized Study.

School-based psychosocial interventions are increasingly put forward as a way to support young refugees' and migrants' well-being and mental health in resettlement. However, the evidence on these interventions' effectiveness remains scarce and scholars denounce particular gaps in the evidence to date, pointing to a lack of large-scale, controlled studies and studies including social outcome measures. This cluster randomized study aims to strengthen the evidence base on school-based psychosocial interventions for refugee and migrant youth by assessing the effect of two interventions, Classroom Drama and Welcome to School, on youth's mental health, resilience, and social relations in Belgium, Denmark, Norway, and the United Kingdom.

Small intestine vs. colon ecology and physiology: Why it matters in probiotic administration.

Research on gut microbiota has generally focused on fecal samples, representing luminal content of the large intestine. However, nutrient uptake is restricted to the small intestine. Abundant immune cell populations at this anatomical site combined with diminished mucus secretion and looser junctions (partly to allow for more efficient fluid and nutrient absorption) also results in intimate host-microbe interactions despite more rapid transit.

A Tool for Assessing the Quality of Life of Adolescents in Youth Care: Psychometric Properties of the QOLYSS.

Quality of life (QOL) has gained increased interest as a critical pathway to better understanding the lives and circumstances of children and adolescents in both the general population and among specific populations. Yet, QOL assessment among youngsters in youth care services remains a highly under-researched topic. This study examines the suitability and psychometric properties of a new QOL self-report scale for adolescents between 12 and 18 years old in youth care: the Quality of Life in Youth Services Scale (QOLYSS).

Checklist of the diatoms (Bacillariophyta) from Lake Naivasha, Kenya, with some historical notes.

Lake Naivasha is one of only two large freshwater lakes in the Eastern Rift Valley of Kenya, East Africa. Together with its satellite lakes Crescent Island Crater, Oloidien and Sonachi, it comprises a great variety of pelagic and benthic habitats for aquatic biota, and its sediment record represents a unique archive of past climate change and long-term ecosystem dynamics in equatorial East Africa. This is particularly so because local paleoenvironmental reconstructions can be checked against historical data on the composition of aquatic fauna and flora collected in Lake Naivasha since the early 20 century.

Inventory of the terrestrial isopods in Belgium (2011-2020).

This data paper describes a recent and spatially complete inventory of the terrestrial isopods of Belgium between 2011 and 2020. During these 10 years every 10 × 10 km² cell of the Universal Transverse Mercator (UTM) grid in Belgium (373 grid cells) was visited in search for terrestrial isopods. Inventories covered different habitat types in every grid cell such as forest, wetlands or stream sides, and urban areas.

Intersexuality in a natural population of the terrestrial isopod .

Intersex phenotypes are rarely observed in natural isopod populations and their expression is typically associated with infection of , a reproductive parasite that manipulates arthropod reproduction. During an intensive sampling effort of a natural population of the isopod , an adult individual was isolated that expressed both male and female traits. The intersex individual exhibited clearly developed external male genitalia and carried multiple eggs in its brood pouch.

Integrative analysis reveals cryptic speciation linked to habitat differentiation within Albanian populations of the anomalous blues (Lepidoptera, Lycaenidae, Latreille, 1804).

The Balkan Peninsula is one of the greatest hotspots for biodiversity in Europe. While the region has been investigated thoroughly, some parts remain understudied and may still harbour undiscovered diversity, even in well-studied organisms such as Lepidoptera. Here we investigated the group of the so-called anomalous blue butterflies, also known as 'brown complex' of the subgenus Agrodiaetus Hübner, 1822 including the taxa of the entire (Brown, 1976) species complex.

Should I, can I, dare I? Patients' view on stopping long-term antidepressant use, a qualitative study.

Background And Aim: The rise in long-term antidepressant use is concerning. Long-term antidepressant (AD) use, much longer than recommended by guidelines, can result in risk of adverse events and generate unnecessary costs. In order to mitigate these risks, patients views about their antidepressants and how to discontinue need to be taken into account.

Single yeast cell nanomotions correlate with cellular activity.

Living single yeast cells show a specific cellular motion at the nanometer scale with a magnitude that is proportional to the cellular activity of the cell. We characterized this cellular nanomotion pattern of nonattached single yeast cells using classical optical microscopy. The distribution of the cellular displacements over a short time period is distinct from random motion.
