Case Reports
Left coronary artery anomaly: an often unsuspected cause of sudden death in the military athlete.
More than 300,000 cases of sudden cardiac death (SCD) occur in the United States each year. Left coronary artery anomaly (LCAA), although rare, is second only to hypertrophic cardiomyopathy as the most common cause of SCD associated with structural cardiovascular abnormalities. This case illustrates SCD secondary to LCAA in a military athlete. ⋯ A substantial proportion of these individuals experience prodromal symptoms of exertional chest pain, syncope, and/or sudden collapse. Early recognition and intervention are key to survival. Rapid, early imaging and invasive therapeutic measures leading to surgical correction may be the difference between life and death.

The purpose of our study was to investigate possible risk factors and mechanisms for the development of pelvic stress fractures in female Navy recruits. We used a case-control retrospective study of female Navy recruits undergoing basic military training. ⋯ In addition, recruits with pelvic stress fractures reported marching in the back of their training division, were road guards, and felt that their stride was too long during training activities more often than recruits without injury. Self-reported fitness, activities before recruit training, or a history of amenorrhea was not found to be associated with the development of a pelvic stress fracture in our population.

Helicobacter pylori has generated public health interest since its identification in 1983. Past studies have suggested that the bacterium plays a role in the pathogenesis of gastric cancer. More recent studies support the conclusion that the association of H. pylori with gastric cancer is causal. The purpose of this article is to review the available evidence supporting the association of H. pylori with gastric cancer. ⋯ New studies that focus on the epidemiology and pathology of H. pylori improve our understanding of its relationship with gastric cancer and advance the development of gastric cancer prevention and control strategies that are proposed.

Multicenter Study
Demographic and psychosocial risk factors for preterm delivery in an active duty pregnant population.
The effects of work climate, pregnancy transitions stress, maternal medical conditions, health risk behaviors, psychological health, and demographic characteristics were examined among 269 pregnant military women. The study found that single and separated/divorced military women were at greater risk for preterm delivery than married women. ⋯ Psychosocial variables distinguished the three marital status groups--married, single, and separated/divorced--but none of these variables was related to preterm delivery. In a logistic regression analysis, marital status was a more significant predictor of preterm delivery than were medical conditions.
