What makes the best medical ethics journal? A North American perspective.

BACKGROUND: There currently exist no data on the factors that contribute to determining why medical ethicists choose to review for and submit articles to medical ethics journals. OBJECTIVE: To establish which factors contribute to medical ethicists reviewing articles for or submitting them to medical ethics journals by consulting those who are active in this capacity. METHODS: Medical ethicists were surveyed to determine their incentives and disincentives for reviewing articles for or submitting them to medical ethics journals. Survey participants were chosen based on a review of the academic and research record of medical ethicists working in North America in higher education institutions. RESULTS: The most frequent incentives to reviewing journal articles were: an opportunity to contribute to the field/profession, the good reputation of the journal, the high impact factor of the journal, and to keep up to date on current research. The most frequent disincentives to reviewing journal articles were: time constraints due to academic commitments, the poor reputation of the journal, and time constraints caused by other editorial commitments (for example, reviewing for other journals/publishers). The most important incentives to submitting journal articles were: the good reputation of the journal, the quality of scholarship previously published in the journal, the impact factor of the journal, and a fast turn-around from acceptance to publication. The most important disincentives to submitting journal articles were: the poor reputation of the journal, the poor quality of work previously published in the journal, and a slow turn-around from acceptance to publication. CONCLUSION: A series of factors that medical ethics journals should strive to employ to encourage reviewing and submission of articles are recommended.

Iron overload and iron-chelating therapy in hemoglobin E-beta thalassemia.

Whereas hemoglobin (Hb) E-beta thalassemia is recognized as probably the most common serious hemoglobinopathy worldwide, its natural history remains poorly defined. The interaction of hemoglobin E and beta-thalassemia result in a wide spectrum of clinical disorders, some indistinguishable from thalassemia major and some milder and not transfusion-dependent. Partially as a result of this wide range of phenotypes, clear guidelines for approaches to transfusion and to iron-chelating therapy for patients with Hb E-beta thalassemia have not been developed. By contrast, data that have accumulated during the past 10 years in patients with beta-thalassemia permit a quantitative approach to the management of iron overload and provide guidelines for the control of body iron burden in individual patients treated with iron-chelating therapy. These guidelines may be applicable to patients with Hb E-beta thalassemia. Preliminary evidence from our studies of iron loading in affected patients with Hb E-beta thalassemia in Sri Lanka suggest that this disorder may be associated with variable, but accelerated, gastrointestinal iron absorption, and that the iron loading associated with chronic transfusions in patients with Hb E-beta thalassemia is similar to that observed in patients with beta-thalassemia. These data, in the only cohort of patients with Hb E-beta thalassemia to have undergone quantitative assessment of body iron burden, suggest that the principles that guide assessment of iron loading and initiation of chelating therapy in patients with beta-thalassemia may be generally applicable to those with Hb E-beta thalassemia. Further quantitative studies in both nontransfused and transfused patients will be necessary to permit firm conclusions.
