increasing numbers of women are deployed to austere settings in which menstruation may impose logistical challenges. Minimal data exists about the use of oral contraceptive pills (OCPs) for menstrual suppression in this population. Post-deployment survey was undertaken to establish prevalence of continuous OCP use, perceived barriers, and associations with menstrual burden in a military population within the austere environment.

Increasing numbers of women perform aviation duties in the combat flight environment. Oral contraceptive pills (OCPs) afford numerous health and operational benefits, including prevention of anemia and suddenly incapacitating conditions, as well as menstrual suppression when taken continuously. Until now, the use of OCPs in the combat flight environment has not been examined.

Ischemic preconditioning (PC) is associated with slower destruction of the adenine nucleotide pool ( summation operatorAd) and slower rate of anaerobic glycolysis during ischemic stress. These changes are concordant with the preconditioned state, supporting an essential role of lowered energy demand in the cardioprotective mechanism of PC. Although pharmacological PC induced by the activation of mitochondrial K(ATP) channels also limits infarct size, its effect on energy metabolism during sustained ischemia is unknown.

To test whether cardioprotection induced by ischemic preconditioning depends on the opening of mitochondrial ATP-sensitive K(+) (K(ATP)) channels, the effect of channel blockade was studied in barbital-anesthetized open-chest pigs subjected to 30 min of complete occlusion of the left anterior descending coronary artery and 3 h of reflow. Preconditioning was elicited by two cycles of 5-min occlusion plus 10-min reperfusion before the 30-min occlusion period. 5-Hydroxydecanoate (5 mg/kg iv) was injected 15 min before preconditioning or pharmacological preconditioning induced by diazoxide (3.
