End-of-life care planning: improving documentation of advance directives in the outpatient clinic using electronic medical records.

Background: The right to self-determination is fundamental in clinical ethics. End-of-life conversations and advance directives (ADs), in addition to preserving this right, have been shown to decrease the likelihood of in-hospital death, improve the quality of care, and lower health costs in the final week of life. Despite these benefits, the rates of AD documentation are poor.

Presence of a peptide component of thymosin fraction-5 manifesting discrete cytostatic properties in HL-60 human promyelocytic leukemia cells.

Thymosin fraction-5 (TF5), an array of small molecular weight peptides present in crude extracts of the adult bovine thymus, contains numerous constituents with demonstrable biological activity. Because TF5 generally enhances immune reactivity in a variety of settings, and additionally restricts proliferation of certain neoplasms, we examined the effects of TF5 on proliferative capacity in the human promyelocytic leukemia cell line HL-60. Vital dye-exclusion, oxidative metabolism of chromogenic dyes, and clonogenic growth profiles were monitored to assess rates of cellular proliferation; our results demonstrate that TF5 restricted HL-60 cell growth, an influence that exhibited comparable potency and efficacy among all three indices.
