AIMS/HYPOTHESIS Plasminogen activator inhibitor-1 (PAI-1) has been regarded as the main antifibrinolytic protein in diabetes, but recent work indicates that complement C3 (C3), an inflammatory protein, directly compromises fibrinolysis in type 1 diabetes. The aim of the current project was to investigate associations between C3 and fibrinolysis in a large cohort of individuals with type 2 diabetes. METHODS Plasma levels of C3, C-reactive protein (CRP), PAI-1 and fibrinogen were analysed by ELISA in 837 patients enrolled in the Edinburgh Type 2 Diabetes Study. Fibrin clot lysis was analysed using a validated turbidimetric assay. RESULTS Clot lysis time correlated with C3 and PAI-1 plasma levels (r = 0.24, p < 0.001 and r = 0.22, p < 0.001, respectively). In a multivariable regression model involving age, sex, BMI, C3, PAI-1, CRP and fibrinogen, and using log-transformed data as appropriate, C3 was associated with clot lysis time (regression coefficient 0.227 [95% CI 0.161, 0.292], p < 0.001), as was PAI-1 (regression coefficient 0.033 [95% CI 0.020, 0.064], p < 0.05) but not fibrinogen (regression coefficient 0.003 [95% CI -0.046, 0.051], p = 0.92) or CRP (regression coefficient 0.024 [95% CI -0.008, 0.056], p = 0.14). No correlation was demonstrated between plasma levels of C3 and PAI-1 (r = -0.03, p = 0.44), consistent with previous observations that the two proteins affect different pathways in the fibrinolytic system. CONCLUSIONS/INTERPRETATION Similarly to PAI-1, C3 plasma levels are independently associated with fibrin clot lysis in individuals with type 2 diabetes. Therefore, future studies should analyse C3 plasma levels as a surrogate marker of fibrinolysis potential in this population.

A Framework for a Consultation Process: Transboundary cooperation and sustainable water management is urgently needed in the up-stream/down-stream situation of the Umbeluzi River Basin between the Kingdom of Swaziland and the Republic of Mozambique. Thus, the Joint Water Commission (JWC) of the two riparian countries initiated the Umbeluzi River Basin Initiative (URBI) with the objective to develop a joint management plan of the river basin. In response to the request by SADC as well as SDC, a collaboration within CDE’s Eastern and Southern Africa Partnership Programme ESAPP was agreed upon. The project’s general objective is to provide conceptual and methodological support in the design of a consultative process with the aim to assure the participation of all water users within the river basin.

Purpose: Leadership positions are still stereotyped as male, especially in male-dominated fields such as STEM. Therefore, women in such positions run the risk of being evaluated less favorably than men. Our study investigates how female and male leaders in existing teams (engineering project) are evaluated, and how these evaluations change over time. Design/Methodology: Participants worked in 45 teams to develop specific engineering projects. Evaluations of 45 leaders (33% women) by 258 team members (39% women) were analyzed, that is, leaders’ self-evaluation and their evaluation by team members. Results: Although female and male leaders did not differ in their self-evaluations at the beginning of the project, female leaders evaluated themselves better within time. However, team members evaluated female leaders better than male leaders at the beginning of the project. These gender differences disappeared over the time. Limitations: It should be replicated in a non-student sample. Implications: The results show that female leaders entering a male-dominated field (engineering) are evaluated better by team members than male leaders at the beginning of the team work, in line with the ‘shifting standard model’ (Biernat & Fuegen, 2001). While the initial impression formation of female and male leaders is influenced by category membership, its impact decreases over time as a consequence of individualization (Fiske & Neuberg, 1990); this results in similar evaluations over time. Originality: To our knowledge this is the first study to systematically test perceptions of change in the evaluation over time of female and male leaders in natural setting.
