Abu Ghraib and the War against Terror - a case against Donald Rumsfeld

The pictures of the inhuman and abusive treatment of Iraqi prisoners at the Abu Ghraib prison shocked the world. The authors of this contribution will take a criminological approach to the crimes committed and will show—by using an analytical framework used by organizational criminologists—that the abuse and torture at Abu Ghraib was an inevitable outcome of the War on Terror as launched by the U.S. administration in a reaction to the terrorist attack launched against it. The abuse at Abu Ghraib which violated U.S. as well as international human rights law was not caused by a few rotten apples as policymakers tried to make us believe, but was a clear example of a state crime. A state crime for which U.S. leaders within the Bush administration such as the Secretary of Defense Donald Rumsfeld, might be held criminally responsible if they would be prosecuted by the ICC

Maximal exercise and muscle oxygen extraction in acclimatizing lowlanders and high altitude natives

The tight relation between arterial oxygen content and maximum oxygen uptake ([Image: see text]) within a given person at sea level is diminished with altitude acclimatization. An explanation often suggested for this mismatch is impairment of the muscle O(2) extraction capacity with chronic hypoxia, and is the focus of the present study. We have studied six lowlanders during maximal exercise at sea level (SL) and with acute (AH) exposure to 4100 m altitude, and again after 2 (W2) and 8 weeks (W8) of altitude sojourn, where also eight high altitude native (Nat) Aymaras were studied. Fractional arterial muscle O(2) extraction at maximal exercise was 90.0 ± 1.0% in the Danish lowlanders at sea level, and remained close to this value in all situations. In contrast to this, fractional arterial O(2) extraction was 83.2 ± 2.8% in the high altitude natives, and did not change with the induction of normoxia. The capillary oxygen conductance of the lower extremity, a measure of oxygen diffusing capacity, was decreased in the Danish lowlanders after 8 weeks of acclimatization, but was still higher than the value obtained from the high altitude natives. The values were (in ml min(−1) mmHg(−1)) 55.2 ± 3.7 (SL), 48.0 ± 1.7 (W2), 37.8 ± 0.4 (W8) and 27.7 ± 1.5 (Nat). However, when correcting oxygen conductance for the observed reduction in maximal leg blood flow with acclimatization the effect diminished. When calculating a hypothetical leg [Image: see text] at altitude using either the leg blood flow or the O(2) conductance values obtained at sea level, the former values were almost completely restored to sea level values. This would suggest that the major determinant for [Image: see text] not to increase with acclimatization is the observed reduction in maximal leg blood flow and O(2) conductance

Cardiac output measurement using a modified carbon dioxide Fick method: a validation study in ventilated lambs.

Contains fulltext : 52992.pdf (publisher's version ) (Closed access)Cardiac output can be measured using a modified carbon dioxide Fick (mCO2F) method. A validation study was performed comparing mCO2F method-derived cardiac output (Q(mCO2F)) with invasively measured pulmonary blood flow. In seven randomly bred ventilated newborn lambs, cardiac output was manipulated by creating hemorrhagic hypotension. When steady state was reached, Q(mCO2F) was measured. Gas analysis was performed in simultaneously obtained arterial and venous blood samples (right atrium [RA], superior vena cava [SVC], and inferior vena cava [IVC]). Carbon dioxide exchange and pulmonary blood flow was measured continuously using a CO2SMO Plus monitor and a pulmonary ultrasonic flow probe (Q), respectively. Mean bias, defined as Q(mCO2F) - Q(ufp), was small (respectively, -0.082 L.min, -0.085 Lx min(-1) and -0.183 Lxmin(-1) for venous sampling from RA, SVC, and IVC). The limits of agreement were -0.328 to 0.164 Lxmin(-1) (RA), -0.335 to 0.165 Lxmin(-1) (SVC), and 0.415 to 0.049 Lxmin(-1) (IVC). In conclusion, measurement of cardiac output with the mCO2F method is reliable and easily applicable in ventilated newborn lambs. For clinical use, the site of venous blood sampling is of minor importance
