Women comprise about half of senior epidemiologists, but little is known about whether they are also viewed as leaders (i.e., authorities) in the field. We believe editorial roles are markers of leadership in a field. Our objective was to describe the distribution of gender across authorship of editorials published in 5 high-impact epidemiology journals over the past 8 years. We included editorials and commentaries published in American Journal of Epidemiology, European Journal of Epidemiology, Epidemiology, International Journal of Epidemiology, and Journal of Clinical Epidemiology between 2010 and 2017. We classified genders of all authors as woman, man, or unknown and computed the proportions of women editorial authors over all journals and according to position (e.g., first author). Only 31% (682/2,228) of all editorial authors and 36% (524/1,477) of unique editorial authors (i.e., counting each editorial author name only once) were women. We identified 1,180 editorials; 594 had sole authors, 24% (141/594) of whom were women, and 586 had 2 or more authors, 31% (184/586) of which had women as first authors. If women are underrepresented as editorial authors across epidemiology journals (e.g., as a marker of epidemiology leadership), the situation merits immediate correction.

Background-The first Björk-Shiley convexoconcave (BSCC) prosthetic heart valves were implanted in 1978. The 25th anniversary provided a stimulus to summarize the research data relevant to BSCC valve fracture, patient management, and current clinical options.

A controlled clinical trial was conducted to determine the feasibility of offering group psychotherapy to post-myocardial infarction patients for one year, and to test its effects upon prognosis. Shortly after discharge from a coronary care unit, 118 patients were approximately equally allocated to therapy and control groups. The acceptance, the average attendance at the weekly sessions, and the drop-out rates per cent were 84, 69 and 15.5 respectively. No statistically significant changes were shown in the physiological and psychological factors. Favorable effects were suggested by survival experience, changes in social alienation, length of hospital stay and the patients' reported attitudes toward this form of therapy.
