    BACKGROUND: Celiac artery stenosis (CAS) may be caused by atherosclerotic degeneration or compression exerted by the arched ligament of the diaphragm. Mitral valve prolapse (MVP) is the most common valvular disorder. There are no reports on an association between CAS and MVP. METHODS: 1560 (41%) out of 3780 consecutive patients undergoing echocardiographic assessment of MVP, had Doppler sonography of the celiac tract to detect CAS. RESULTS: CAS was found in 57 (3.7%) subjects (23 males and 34 females) none of whom complained of symptoms related to visceral ischemia. MVP was observed in 47 (82.4%) subjects with and 118 (7.9%) without CAS (p < 0.001). The agreement between MVP and CAS was 39% (95% CI 32–49%). PSV (Peak Systolic Velocity) was the only predictor of CAS in MPV patients (OR 0.24, 95% CI 0.08–0.69) as selected in a multivariate logistic model. CONCLUSION: CAS and MVP seem to be significantly associated in patients undergoing consecutive ultrasonographic screening

    The human capital transition and the role of policy

    Along with information and communication technology, infrastructure, and the innovation system, human capital is a key pillar of the knowledge economy with its scope for increasing returns. With this in mind, the purpose of this chapter is to investigate how industrialized economies managed to achieve the transition from low to high levels of human capital. The first phase of the human capital transition was the result of the interaction of supply and demand, triggered by technological change and boosted by the demands for (immaterial) services. The second phase of the human capital transition (i.e., mass education) resulted from enforced legislation and major public investment. The state’s aim to influence children’s beliefs appears to have been a key driver in public investment. Nevertheless, the roles governments played differed according to the developmental status and inherent socioeconomic and political characteristics of their countries. These features of the human capital transition highlight the importance of understanding governments’ incentives and roles in transitions

    African Jobless Growth Morphology: Vulnerabilities and Policy Responses

    As by product of economic growth, jobs are indeed transformational. In other words, efficiency increases as workers get better at what they do (as more productive jobs appear and less productive one disappear). In fact societies flourish as jobs bring together people from different ethnic and social backgrounds while providing alternatives to conflict. Unfortunately, in many African countries, unemployment rates are low and growth is seldom jobless. Regrettably, most of the poor work long hours and cannot make ends meet while the violation of basic human rights is not uncommon. Again, youth unemployment and unmet job expectations are alarming. Consequently, this paper provides a framework that cuts across sectors and shows that the best policy responses vary across African countries (depending on their levels of development, endowments, demography and institutions). Thus, at all stages of development, forcing economic production to spread evenly across areas is both elusive and expensive. Policy makers should therefore identify and execute strategies that balance development outcomes across areas by means of domestic integration instruments. However, in places where integration is hardest, the policy response should be comprehensively total: institutions that unite, infrastructure that connects, interventions that target, incentives that motivate as well as information and communication technologies that enables or drives
