Long-term development of loneliness in older people and associations with stringency of COVID-19 measures: an observational cohort study.

Background: Most longitudinal studies found heightened feelings of loneliness in older people in spring 2020 compared to times before the pandemic. However, longer-term effects are more disputed. We, therefore, investigated changes in loneliness in older people throughout the first 21 months of the COVID-19 pandemic in Switzerland and examined the association between the stringency of COVID-19 measures and feelings of loneliness.

Data literacy in genome research.

With an ever increasing amount of research data available, it becomes constantly more important to possess data literacy skills to benefit from this valuable resource. An integrative course was developed to teach students the fundamentals of data literacy through an engaging genome sequencing project. Each cohort of students performed planning of the experiment, DNA extraction, nanopore sequencing, genome sequence assembly, prediction of genes in the assembled sequence, and assignment of functional annotation terms to predicted genes.

Treatment of very elderly glioblastoma patients ≥ 75 years of age: whom to treat.

Purpose: The prognosis of patients ≥ 75 years suffering from glioblastoma is poor. Novel therapies are usually reserved for patients ≤ 70 years. In an aging population, treatment of very elderly patients remains a challenge.

Macroparticle-enhanced cultivation of Lentzea aerocolonigenes: Variation of mechanical stress and combination with lecithin supplementation for a significantly increased rebeccamycin production.

The actinomycete Lentzea aerocolonigenes produces the antitumor antibiotic rebeccamycin. In previous studies the rebeccamycin production was significantly increased by the addition of glass beads during cultivation in different diameters between 0.5 and 2 mm and the induced mechanical stress by the glass beads was proposed to be responsible for the increased production.
