First Into the Lifeboats: Protecting Medical Student Education During the Hahnemann University Hospital Closure.

The announcement of the closure of Philadelphia's Hahnemann University Hospital in June 2019 sent shock waves through the academic community. The closure had a devastating impact on the residents and fellows who trained there, the patients who had long received their care there, and faculty and staff who had provided care there for decades. Since its beginnings, the hospital, established as part of Hahnemann Medical College in 1885, was a major site for medical student education. The authors share the planning before and actions during the crisis that protected the educational experiences of third- and fourth-year medical students at Drexel University College of Medicine assigned to Hahnemann University Hospital. The lessons they learned can be helpful to leadership in academic health systems in the United States facing a diminishing number of clinical training sites for medical and other health professions students, a situation that is likely to worsen as the COVID-19 pandemic continues to weaken the health care ecosystem.

Effect of a four-week course of interleukin-10 on cytokine production in a placebo-controlled study of HIV-1-infected subjects.

Interleukin (IL)-10 suppresses synthesis of the pro-inflammatory cytokines tumor necrosis factor (TNF)alpha, IL-1beta, and interferon (IFN)gamma. Since pro-inflammatory cytokines have been implicated in the production of human immunodeficiency virus type 1 (HIV-1), cytokine synthesis in whole blood cultures were determined during a 4-week course of subcutaneous IL-10 injections in 33 HIV-1-infected patients. Patients were randomized into four groups: placebo (nine), IL-10 at 1 microg/kg/day (nine), IL-10 at 4 microg/kg/day (six) and IL-10 at 8 microg/kg three times per week (nine). Whole blood was obtained at the beginning and conclusion of the study and was stimulated for 24 hours with the combination of IL-18 plus lipopolysaccharide. TNFalpha production in stimulated whole blood was reduced three and six hours after the first injection of IL-10 compared to subjects injected with the placebo. After four weeks of treatment, production of IFNgamma was suppressed in a greater number of patients in the IL-10 treatment groups compared to subjects in the placebo group. Similarly, IL-1beta production was lower in the IL-10 treatment groups compared to subjects receiving placebo. In contrast, after four weeks of IL-10, circulating levels of the anti-inflammatory TNF soluble receptor p55 increased dose-dependently compared to placebo subjects. Patient heterogeneity and small sample size presented difficulties in establishing statistical significance. Although the cytokine changes in our study did not demonstrate statistically significant changes, the data nevertheless reveal that four weeks of IL-10 therapy in HIV-1 infected subjects produced the anticipated suppression of pro-inflammatory cytokines.
