Infectious disease is the most common cause of illness and death in Africa, yet health practitioners routinely fail to identify causative microorganisms in most patients. As a result, patients often do not receive the right medicine in time to cure them promptly even when such medicine is available, outbreaks are larger and more devastating than they should be, and the impact of control interventions is difficult to measure. Wrong prescriptions and prolonged infections amount to needless costs for patients and for health systems. In Divining without Seeds, Iruka N. Okeke forcefully argues that laboratory diagnostics are essential to the effective practice of medicine in Africa.The diversity of endemic life-threatening infections and limited public health resources in tropical Africa make the need for basic laboratory diagnostic support even more acute than in other parts of the world. This book gathers compelling case studies of inadequate diagnoses of diseases ranging from fevers—including malaria—to respiratory infections and sexually transmitted diseases. The inherited and widely prevalent health clinic model, which excludes or diminishes the hospital laboratory, is flawed, to often devastating effect. Fortunately, there are new technologies that make it possible to inexpensively implement testing at the primary care level. Divining without Seeds makes clear that routine use of appropriate diagnostic support should be part of every drug delivery plan in Africa and that diagnostic development should be given high priority.

Background The factors that contribute to the abnormal knee kinematics after anterior cruciate ligament (ACL) injury and ACL reconstruction remain unclear. Bone shape has been implicated in the development of hip and knee osteoarthritis, although there is little knowledge about the effects of bone shape on knee kinematics after ACL injury and after ACL reconstruction. Questions/questions (1) What is the relationship between bony morphology with alterations in knee kinematics after ACL injury? (2) Are baseline bone shape features related to abnormal knee kinematics at 12 months after ACL reconstruction? Methods Thirty-eight patients (29 ± 8 years, 21 men) were prospectively followed after acute ACL injury and before ligamentous reconstruction. Patients were excluded if there was a history of prior knee ligamentous injury, a history of inflammatory arthritis, associated meniscal tears that would require repair, or any prior knee surgery on either the injured or contralateral side. In total, 54 patients were recruited with 42 (78%) patients completing 1-year followup and four patients excluded as a result of incomplete or unusable imaging data. MR images were obtained for the bilateral knees at two time points 1 year apart for both the injured (after injury but before reconstruction and 1 year after reconstruction) and contralateral uninjured knees. Kinematic MRI was performed with the knee loaded with 25% of total body weight, and static images were obtained in full extension and in 30° of flexion. The side-to-side difference (SSD) between tibial position in the extended and flexed positions was determined for each patient. Twenty shape features, referred to as modes, for the tibia and femur each were extracted independently from presurgery scans with the principal component analysis-based statistical shape modeling algorithm. Spearman rank correlations were used to evaluate the relationship between the SSD in tibial position and bone shape features with significance defined as p < 0.05. Each of the shape features (referred to as the bone and mode number such as Femur 18 for the 18th unique femoral bone shape) associated with differences in tibial position was then investigated by modeling the mean shape ± 3 SDs. Results Two of the 20 specific femur bone shape features (Femur 10, Femur 18) and two of the 20 specific tibial bone shape features (Tibia 19, Tibia 20) were associated with an increasingly anterior SSD in the tibial position for the patients with ACL injury before surgical treatment. The shape features described by these modes include the superoinferior height of the medial femoral condyle (Femur 18; ρ = 0.33, p = 0.040); the length of the anterior aspect of the lateral tibial plateau (Tibia 20; ρ = −0.35, p = 0.034); the sphericity of the medial femoral condyle (Femur 10; ρ = −0.52, p < 0.001); and tibial slope (Tibia 19; ρ = 0.34; p = 0.036). One year after surgical treatment, there were two of 20 femoral shape features that were associated with SSD in the tibial position in extension (Femur 10, Femur 18), one of 20 femoral shape features associated with SSD in the tibial position in flexion (Femur 10), and three of 20 tibial shape features associated with SSD in the tibial position in flexion (Tibia 2, Tibia 4, Tibia 19). The shape features described by these modes include the sphericity of the medial femoral condyle (Femur 10; ρ = −0.38, p = 0.020); the superoinferior height of the medial femoral condyle (Femur 18; ρ = 0.34, p = 0.035); the height of the medial tibial plateau (Tibia 2; ρ = −0.32, p = 0.048); the AP length of the lateral tibial plateau (Tibia 4; ρ = −0.37, p = 0.021); and tibial slope (Tibia 19; ρ = 0.34, p = 0.038). Conclusions We have observed multiple bone shape features in the tibia and the femur that may be associated with abnormal knee kinematics after ACL injury and ACL reconstruction. Future directions of research will include the influence of bony morphology on clinical symptoms of instability in patients with and without ACL reconstruction and the long-term evaluation of these shape factors to better determine specific contributions to posttraumatic arthritis and graft failure.

This title outlines a number of practical initiatives to strengthen the role of development communication in infrastructure projects. The authors aim to facilitate better quality projects and to build consensus on the type of governance reforms needed to fight corruption, drawing on the experience of development agencies like the World Bank and Transparency International. It starts by characterizing corruption vulnerabilities in infrastructure and proceeds to illustrate where communication has added value on a number of recent projects, both in regard to making the projects more sustainable and by incorporating anti-corruption measures into the project preparation and implementation. It draws on examples of mainly World Bank-supported projects from the road, transport, power, and water sectors in different governance contexts. Five standard-setting initiatives are then outlined, which focus on promoting best practice to better integrate development communication into the project cycles of World Bank-supported infrastructure projects.

Old saw: Collinearity will not harm forecasts as long as it continues into the forecast period. If, however, collinearity is unlikely to continue but has already harmed estimation, then corrective action (introduction of prior information) to improve estimates should improve forecasts. This paper marshals the diagnostic information needed to assess collinearity's continuance and, when required, to direct meaningful corrective action. The process is illustrated by an example involving forecasts using energy prices.
