Reasons for emergency department use: do frequent users differ?
Frequent ED users gave similar reasons for using the ED for low-acuity health complaints compared with nonfrequent ED users. Access, convenience, cost, and quality concerns, as well as feeling that ED care was needed, were all commonly cited as reasons for using the ED.
The results of the present study show that lack of CD8(+) T cells or NKT cells abolishes the immunosuppressive effect of antidepressant drugs on PCL-induced CHS reaction in mice. These results suggest that antidepressant drug-induced inhibition of CHS reaction is connected with their inhibitory effect on ability of CD8(+) T cells and NKT cells to induce and/or escalate CHS reaction. TCRγδ cells seem not to be involved in antidepressant-induced suppression of CHS.
