Objective We sought to determine the accuracy of the LOW‐HARM score (Lymphopenia,
Oxygen saturation, White blood cells, Hypertension, Age, Renal injury, and Myocardial
injury) for predicting death from coronavirus disease 2019) COVID‐19. Methods We derived
the score as a concatenated Fagan's nomogram for Bayes theorem using data from
published cohorts of patients with COVID‐19. We validated the score on 400 consecutive
COVID‐19 hospital admissions (200 deaths and 200 survivors) from 12 hospitals in Mexico …

Recent models suggest a relationship exists between community diversity and pathogen
prevalence, the proportion of individuals in a population that are infected by a pathogen,
with most inferences tied to assemblage structure. Two contrasting outcomes of this
relationship have been proposed: the “dilution effect” and the “amplification effect.” Small
mammal assemblage structure in disturbed habitats often differs from assemblages in sylvan
environments, and hantavirus prevalence is often negatively correlated with habitats …
