Premature coronary artery disease (CAD) is a major concern in human immunodeficiency virus (HIV)-infected African Americans. The objectives of the study were to estimate the incidence of subclinical CAD, defined by the presence of coronary plaque and/or calcification on cardiac computed tomography (CT), and to identify the associated risk factors in this vulnerable population. ⋯ The incidence of subclinical CAD in African Americans with HIV infection is provocatively high. Larger studies are warranted to confirm the role of vitamin D deficiency in the development of CAD in HIV-infected African Americans.

Academic institutions and researchers are becoming increasingly involved in translational research to spur innovation in addressing many complex biomedical and societal problems and in response to the focus of the National Institutes of Health and other funders. One approach to translational research is to develop interdisciplinary research teams. By bringing together collaborators with diverse research backgrounds and perspectives, these teams seek to blend their science and the workings of the scientists to push beyond the limits of current research. ⋯ In particular, because academic career advancement commonly focuses on individual achievement, team science might differentially impact early stage researchers. The need to be recognized for individual accomplishments to move forward in an academic career may give rise to research team conflicts. Raising awareness to career-related aspects of team science will help individuals (particularly trainees and junior faculty) take steps to align their excitement and participation with the success of both the team and their personal career advancement.

Interdisciplinary efforts are becoming more critical for scientific discovery and translational research efforts. Highly integrated and interactive research teams share a number of features that contribute to their success in developing and sustaining their efforts over time. Through analysis of in-depth interviews with members of highly successful research teams and others who did not meet their goals or ended because of conflicts, we identified key elements that are critical for team success and effectiveness. ⋯ Self-awareness and strong communication skills contribute greatly to effective leadership and management strategies of scientific teams. While all successful teams share the characteristic of effectively carrying out these activities, there is no single formula for execution with every leader exemplifying different strengths and weaknesses. Successful scientific collaborations have strong leaders who are self-aware and are mindful of the many elements critical for supporting the science at the center of the effort.

Serum levels of angiopoietin-related growth factor (AGF) are increased in polycystic ovary syndrome.
Polycystic ovary syndrome (PCOS) is a frequent reproductive and metabolic disorder associated with insulin resistance. Recently, angiopoietins were identified in the systemic circulation and have been designated angiopoietinlike proteins (ANGPTL). More recently, it is shown that angiopoietin-related growth factor (AGF, also called ANGPTL6) directly regulate lipid, glucose, and energy metabolism independent of angiogenic effects in animal studies. The aim of this study was to determine whether there is an association between AGF and PCOS. ⋯ Serum AGF levels were paradoxically increased in patients with PCOS in comparison with data of animal experiments. Further studies are needed to better elucidate the physiologic significance of circulating AGF in human disease.
