Recent findings: Approximately 830 women die every day worldwide as a result of complications related to pregnancy or childbirth with obstetric hemorrhage that remains a major cause of maternal morbidity and mortality. A systematic analysis by the World Health Organization [WHO] on the global causes of maternal deaths from 2003 to 2009 found that bleeding was the leading direct cause of maternal mortality followed by hypertensive disorders and sepsis. Overall, bleeding accounted for 27.1% of all maternal deaths worldwide. The need to implement strategies that mitigate the impact of bleeding in this clinical scenario is increasingly growing. Purpose of review: The purpose of this review is to propose a management strategy based on goals established through dynamic coagulation assessment. Summary: Effective management of obstetric hemorrhage requires rapid recognition, rapid response and mobilization of the multidisciplinary team. Volumetric resuscitation, hemodynamic stability, as well as the simultaneous identification and treatment of the source of bleeding and the resolution of coagulopathy in the shortest possible time remain the cornerstones of the management of Postpartum Hemorrhage (PPH).

Aggressive mimicry occurs when an organism resembles some aspect of another organism （the model） in order to obtain prey through its deceptive resemblance. This may function either through the overt response of the receiver or through the lack of response of the receiver. Reviewing selected examples, I discuss some of the difficulties in ascribing a model for the mimic. I also discuss how a single animal can have multiple ploys in its armoury of deceptive signals, thus belonging within two or more categories of deceptive signalling. In addition to aggressive mimicry, these may include crypsis or camouflage, mas- querade （mimicry of inanimate objects）, and Batesian or protective mimicry. Each of these examples of deception has multiple evolutionary pathways, and some deceptive signals may be more costly to receivers than others, but no single organism is subject to a single selection pressure, leading to the reality that many evolutionary pathways contribute to the diversity we see around us. New technologies are opening new channels of investigation into deceptive signaling in many different sensory modalities, and this is reflected in the recent increase in studies investigating the structure and function of deceptive signals. In turn, these studies are beginning to expose the fascinating complexity of deceptive signaling systems, allowing us to discover the myriad, non-mutually exclusive, solutions that can be selected for to obtain prey

Thrombocytopenia (defined as platelet count 9/L) is present in 7% - 12% of pregnant women at delivery. Although there are mild etiologies of this condition that are often diagnosed incidentally, there are more severe causes that can be life threating. Thrombocytopenia also has a great implication in surgical risk and regional anesthesia. A structured evaluation of thrombocytopenia is necessary to allow an adequate diagnostic approach. Here we summarized the current knowledge of thrombocytopenia in pregnancy.

1 Conservation Behavior as an Emerging Discipline on the Brink of Success, or Unrealistic Ideal？ It seems intuitively sensible that an understanding of the behavioral characteristics of animals, such as their home ranges, diets, mating systems, and dispersal me- chanisms, may be useful to inform conservation efforts in determining, for example, suitable reintroduction areas, or the design of dispersal corridors.

The potential for ornament evolution in response to sexual selection rests on the interaction between the permissive- ness or selectivity of female preferences and the constraints on male development of signaling related traits. We investigate the former by determining how latent female preferences either exaggerate the magnitude of current traits （i.e. elaborations） or favor novel traits （i.e. innovations）. In tt^ngara frogs, females prefer complex mating calls （whine-chucks） to simple calls （whine only）. The whine is critical for mate recognition while the chuck further enhances the attractiveness of the call. Here we use a combina- tion of synthetic and natural stimuli to examine latent female preferences. Our results show that a diversity of stimuli, including conspecific and heterospecific calls as well as predator-produced and human-made sounds, increase the attractiveness of a call when added to a whine. These stimuli do not make simple calls more attractive than a whine-chuck, however. In rare cases we found stimuli that added to the whine decrease the attractiveness of the call. Overall, females show strong preferences for both elaborations and innovations of the chuck. We argue that the emancipation of these acoustic adornments from mate recognition allows such female permissiveness, and that male constraints on signal evolution are probably more important in explaining why males evolved their specific adornment. Experimentally probing latent female preferences for stimuli out of the species＇ range is a useful means to gain insights about the potential of female choice to influence signal evolution and thus the astounding diversity in male sexually-selected traits [Current Zoology 56 （3）： 343-357, 2010].
