In the last decade, there has been increased recognition of the importance of disclosing and managing non-financial conflicts of interests to safeguard the objectivity, integrity, and trustworthiness of scientific research. While funding agencies and academic institutions have had policies for addressing non-financial interests in grant peer review and research oversight since the 1990s, scientific journals have been only recently begun to develop such policies. An impediment to the formulation of effective journal policies is that non-financial interests can be difficult to (...) recognize and define. Journals can overcome this problem by providing guidance concerning the types of non-financial interests that should be disclosed, including direct research interests, direct professional interests, expert testimony, involvement in litigation, holding a leadership position in a non-governmental organization, providing technical or scientific advice to a non-governmental organization, and personal or professional relationships. The guidance should apply to authors, editors, and reviewers. (shrink)

Authorship of a scientific paper is important in recognition of one’s work, and in the academic setting, helps in professional promotion. Conflicting views of authorship have led to disputes and debates in many scientific communities. Addressing ethical issues in medical research and publishing, and conforming to the requirements of international organizations and local research ethics boards, has become an essential part of the research endeavor. Ethical issues of biomedical authorship have been a matter of debate for years. Authorship problems may (...) involve problems with integrity, including ghost authorship and guest authorship. Some scientific disciplines, such as engineering or social sciences, may not have a firm guideline for authorship criteria; however this article reviews the criteria of authorship recommended by related international organizations of biomedical field and discusses common scenarios that may lead to authorship disputes and misconducts as well as issues related to authorship in multicenter studies. The paper also discusses possible scenarios that might be legitimate to make changes in authorship lists. (shrink)
