A survey of an emerging tuberculosis epidemic among the Yanomami Indians of the Amazonian rain forest provided a unique opportunity to study the impact of tuberculosis on a population isolated from contact with the tubercle bacillus for millennia until the mid-1960s. Within the Yanomami population, an extraordinary high prevalence of active tuberculosis (6.4% of 625 individuals clinically examined) was observed, indicating a high susceptibility to disease, even among bacille Calmette–Guérin-vaccinated individuals. Observational studies on cell-mediated and humoral immune responses of the Yanomami Indians compared with contemporary residents of the region suggest profound differences in immunological responsiveness to Mycobacterium tuberculosis infection. Among the Yanomami, a very high prevalence of tuberculin skin test anergy was found. Of patients with active tuberculosis, 46% had purified protein derivative of tuberculosis reactions <10 mm; similarly 58% of recent bacillus Calmette–Guérin vaccines exhibited skin test reactions <5 mm. The Yanomami also had higher titers of antibodies against M. tuberculosis glycolipid antigens (>70%) than the control subjects comprised of Brazilians of European descent (14%). The antibodies were mostly of the IgM isotype. Among the tuberculosis patients who also produced IgG antibodies, the titers of IgG4 were significantly higher among the Yanomami than in the control population. Although it was not possible to analyze T-cell responses or patterns of lymphokine production in vitro because of the remoteness of the villages from laboratory facilities, the results suggest that the first encounter of the Yanomami Indian population with tuberculosis engenders a diminished cell-mediated immune response and an increased production antibody responses, relative to other populations with extensive previous contact with the pathogen. These findings suggest that tuberculosis may represent a powerful selective pressure on human evolution that over centuries has shaped the nature of human immune responses to infection.

The goal of this publication is to attempt to assess the thirteen years (2001- -2014) of the West’s military presence in the countries of post-Soviet Central Asia, closely associated with the ISAF and OEF-A (Operation Enduring Freedom – Afghanistan) missions in Afghanistan. There will also be an analysis of the actual challenges for the region’s stability after 2014. The current and future security architecture in Central Asia will also be looked at closely, as will the actual capabilities to counteract the most serious threats within its framework. The need to separately handle the security system in Central Asia and security as such is dictated by the particularities of political situation in the region, the key mechanism of which is geopolitics understood as global superpower rivalry for influence with a secondary or even instrumental role of the five regional states, while ignoring their internal problems. Such an approach is especially present in Russia’s perception of Central Asia, as it views security issues in geopolitical categories. Because of this, security analysis in the Central Asian region requires a broader geopolitical context, which was taken into account in this publication. The first part investigates the impact of the Western (primarily US) military and political presence on the region’s geopolitical architecture between 2001 and 2014. The second chapter is an attempt to take an objective look at the real challenges to regional security after the withdrawal of the coalition forces from Afghanistan, while the third chapter is dedicated to analysing the probable course of events in the security dimension following 2014. The accuracy of predictions time-wise included in the below publication does not exceed three to five years due to the dynamic developments in Central Asia and its immediate vicinity (the former Soviet Union, Afghanistan, Pakistan, Iran), and because of the large degree of unpredictability of policies of one of the key regional actors – Russia (both in the terms of its activity on the international arena, and its internal developments).

From a historical perspective, the last two decades can almost be regarded as a 'golden age' of Polish-Russian relations. This is the first time in several centuries that a sovereign Poland and Russia have been able to develop mutual relations without resorting to force; moreover, they have established a bilateral legal basis and put into practice its provisions on "the inviolability of borders, territorial integrity, non-interference with internal affairs and the nations' right to self-determination. This does not change the fact that since 1990 the atmosphere between the two countries has much more often been chilly and tense. Contrary to the widely-held belief, Polish-Russian conflicts do not stem from genetic Russophobia on the part of Poland, or irrational prejudice on the part of Russia. Their substance is real and concerns strategic issues. At the deepest level, though, this is a dispute about how far the borders of the Western world extend, and about the Russian Federation's sphere of influence. However, it is not a clash between two states; moreover, Poland is certainly not the most important actor in this regard, although due to the historical context and its geographic location, it is one of the countries that lies closest to the 'line of contact', and is therefore particularly entangled in the disagreement.

China will launch a new development bank for Asia later this year, called the AIIB. 58 countries worldwide have already applied to become founding members, including numerous Western nations. This policy brief argues that the AIIB constitutes an important international development, as it reflects a new geopolitical reality and marks a new turn in China’s practice of multilateralism. It also looks critically at the European uncoordinated response to the AIIB, and what it tells about Europe’s shrinking role in the world.
