Observing many researchers using the same data and hypothesis reveals a hidden universe of uncertainty.

This study explores how researchers' analytical choices affect the reliability of scientific findings. Most discussions of reliability problems in science focus on systematic biases. We broaden the lens to emphasize the idiosyncrasy of conscious and unconscious decisions that researchers make during data analysis.

Cyclosporine A but Not Corticosteroids Support Efficacy of Expanded, Adoptively Transferred Human Tregs in GvHD.

Reshaping the immune balance by adoptive transfer of regulatory T-cells (Tregs) has emerged as a promising strategy to combat undesired immune reactions, including in Graft-versus-Host Disease (GvHD), which is the most lethal non-relapse complication of allogeneic hematopoietic stem cell transplantation. Currently however, little is known about the potentially inhibitory effects of conventional immunosuppressive drugs, which are routinely used to treat GvHD, on adoptively transferred Tregs. Here we demonstrate drug-specific effects of the conventional immunosuppressive drugs Cyclosporine A, Mycophenolate mofetil and methylprednisolone on adoptively transferred Tregs in a humanized NOD/SCID/IL2Rgamma-/- GvHD mouse model.

Is domestic tap water a risk for infections in neutropenic patients?

Background: Home care has become popular in the management of hemato-oncologic patients. Therefore, we conducted a prospective study to assess whether tap water from the domestic environment of neutropenic patients poses a risk for infections from the waterborne pathogens nontuberculous mycobacteria (NTM), Legionella spp., and Pseudomonas aeruginosa.
