TL;DR: It is shown that resistance to Norwalk virus infection is multifactorial, and of the susceptible population that encoded a functional FUT2 gene, a portion was resistant to infection, suggesting that a memory immune response or some other unidentified factor also affords protection from Norovirus infection.

TL;DR: Empirical biological data strongly support the hypothesis that sexual transmission by acutely infected individuals has a disproportionate effect on the spread of HIV-1 infection, and may, in part, explain the current pandemic in heterosexual individuals.

TL;DR: Initiation of recurrent daily intake of 4 g of acetaminophen in healthy adults is associated with ALT elevations and concomitant treatment with opioids does not seem to increase this effect.

TL;DR: Control of Confounding and Reporting of Results in Causal Inference Studies Guidance for Authors from Editors of Respiratory, Sleep, and Critical Care Journals is published.

TL;DR: A rigorous definition of a pilot study is presented, recommendations for the design, analysis and sample size justification of pilot studies in clinical and translational research are offered, and the important role that well‐designed pilot studies play in the advancement of science and scientific careers are emphasized.
