Purpose: This study investigated leukocyte subset responses to moderate-intensity exercise under heat stress, with water (W) or carbohydrate (CHO) drink ingestion. Methods: In repeated trials, 13 soldiers consumed either a W or CHO drink during 3 h of walking at 4.4 km center dot h(-1) with a 5% gradient (15 min rest per hour) under heat stress (35 C and 55% relative humidity). The soldiers wore combat uniforms and carried water bottles and dummy rifles and ammunition, altogether weighing about 11.5 +/- 1.0 kg. Results: Plasma glucose concentration was significantly higher with CHO than W ingestion during exercise (p < 0.01). There were no significant differences between W and CHO conditions in exercise performance, plasma cortisol concentration, heart rate, or core temperature. CHO ingestion significantly moderated the increases in leukocyte (83% in W, 28% in CHO; p < 0.001), monocyte (60% in W, 34% in CHO; p < 0.05), and granulocyte counts (120% in W, 30% in CHO; p < 0.001), but not in lymphocyte count (41% in W, 25% in CHO). Conclusions: The increases in leukocyte and subset counts during moderate-intensity exercise under heat stress may be comparable to those observed during intense exercise in cool conditions. The response of immune cell counts is blunted by CHO intake during moderate-intensity exercise in the heat, and may not occur through the cortisol pathway.

The last decade has witnessed a significant growth in transnational organised crime activities. It has also seen multiple efforts by the international community to come to terms with this rise of organised crime and to work towards an international instrument to combat the activities of criminal organisations. In December 2000, the United Nations opened for signature the Convention against Transnational Organized Crime (2001), also known as the Palermo Convention, a treaty that is supplemented by three protocols on trafficking in persons, smuggling of migrants, and trafficking in firearms and ammunition. The conclusion of the Convention marks the end of more than eight years of consultations on a universal instrument to criminalise and counteract transnational criminal organisations. This article illustrates the developments that led to the Convention against Transnational Organized Crime and reflects on the amendments and concessions that have been made to earlier proposals during the elaboration process. This article highlights the strengths of the Convention in the areas of judicial cooperation and mutual legal assistance, and the shortcomings of the new Convention, in particular in failing to establish a universal, unequivocal definition of “transnational organized crime”.
