A real-world study on the impact of infection load on mortality in multiple myeloma patients in Finland.

Infections are a clinically significant cause of mortality in multiple myeloma (MM) patients. The high number of infections in MM patients is due to the immunosuppressive effects of the disease itself as well as treatment-related immunosuppression. In this real-world evidence (RWE) study, we used several nationwide healthcare registries of Finland to investigate the effect of infection load on mortality in MM patients during 1997-2021.

Cyanobacteria newly isolated from marine volcanic seeps display rapid sinking and robust, high-density growth.

Unlabelled: Cyanobacteria are photosynthetic organisms that play important roles in carbon cycling and are promising bioproduction chassis. Here, we isolate two novel cyanobacteria with 4.6Mbp genomes, UTEX 3221 and UTEX 3222, from a unique marine environment with naturally elevated CO₂.

Constant surface area-to-volume ratio during cell growth as a design principle in mammalian cells.

All cells are subject to geometric constraints, such as surface area-to-volume (SA/V) ratio, that impact cell functions and force biological adaptations. Like the SA/V ratio of a sphere, it is generally assumed that the SA/V ratio of cells decreases as cell size increases. Here, we investigate this in near-spherical mammalian cells using single-cell measurements of cell mass and surface proteins, as well as imaging of plasma membrane morphology.
