An Initial Assessment of the Utility of Validated Alcohol and Drug Screening Tools in Predicting 30-Day Readmission to Adult General Medicine Wards.

Previous studies have identified drug and alcohol use as risk factors for readmission using claims data, but not by using substance use screening scores. This preliminary study tested the hypothesis that prevalence of 30-day readmission would be higher among patients screening positive on the 10-item Alcohol Use Disorders Identification Test (AUDIT-10) or the 10-item Drug Abuse Screening Test (DAST-10) tools at intake than among the general patient population. Social workers screened 4708 adult inpatients using prescreening questions followed by the AUDIT-10 and/or DAST-10.

Chronic contamination decreases disease spread: a Daphnia-fungus-copper case study.

Chemical contamination and disease outbreaks have increased in many ecosystems. However, connecting pollution to disease spread remains difficult, in part, because contaminants can simultaneously exert direct and multi-generational effects on several host and parasite traits. To address these challenges, we parametrized a model using a zooplankton-fungus-copper system.
