Body fluid regulation in a simulated disabled submarine: effects of cold, reduced O2, and elevated CO2.

Introduction: Survivors awaiting rescue aboard a disabled submarine (DISSUB) lacking power and/or environmental control would potentially be exposed to cold and reduced O2 and elevated CO2 levels. We hypothesized that elevated CO2 levels would lead to hormone changes that would mitigate cold and hypoxia-induced body fluid losses.

Methods: Blood was drawn from seven men on three mornings: baseline (21% O2, 0.

Adequacy of Garrison feeding for Special Forces soldiers during training.

This study evaluated whether Special Forces (SF) soldiers training in garrison would meet nutrient intake recommendations using the available garrison dining facility. Dietary intakes were obtained by a visual estimation method and self-reported food records from 32 SF and 13 support soldiers for 9 days. Total energy expenditure (TEE) was measured in nine soldiers from each group using doubly labeled water.

Nutrition knowledge and supplement use among elite U.S. army soldiers.

A U.S. Army Special Forces (SF) unit was studied to determine characteristics of supplement users, assess nutrition knowledge, and identify nutrition information sources.

Iron deficiency is unacceptably high in refugee children from Burma.

Iron-deficiency anemia (IDA) in refugees is reported to be among the major medical problems worldwide. Because food rations are typically inadequate in iron, long-term reliance is a key predictor of anemia among displaced people. Comprehensive nutritional assessments of refugee children from Burma have not previously been completed.
