Vitamin A Deficiency in Pregnancy: Perspectives after Bariatric Surgery

This study aims to describe the clinical consequences of vitamin A deficiency (VAD) in pregnant women after bariatric surgery. Included are studies on VAD during pregnancy and after bariatric surgery conducted in humans from 1993 to 2011. There are few investigations on the relationship between pregnancy and bariatric surgery and on the damage to the binomial mother–child resulting from VAD in this relationship. The high percentage of VAD in the postoperative period is a cause for concern, especially considering the function of this vitamin in certain biological moments and in moments of intense nutritional demand. This vitamin serum evaluation is recommended during the prenatal period.     

Towards Autonomous Creative Systems: A Computational Approach

This paper reviews the long-standing debate surrounding the nature of machine intelligence, autonomy and creativity and argues for an approach to developing autonomous computational creativity that models personal motivations, social interactions and the evolution of domains. The implications of this argument on the types of cognitive processes that are required for the development of autonomous computational creativity are explored and a possible approach to achieving the goal is described. In particular, this paper describes the development of artificial creative systems composed of intrinsically motivated agents engaging in language games to interact with a shared social and cultural environment. The paper discusses the implications that this type of approach may have for the development of autonomous creative systems.
