Vietnam veterans continued to experience higher mortality than non-Vietnam veterans from unintentional poisonings and drug-related causes. Death rates from disease-related chronic conditions, including cancers and circulatory system diseases, did not differ between Vietnam veterans and their peers, despite the increasing age of the cohort (mean age, 53 years) and the longer follow-up (average, 30 years).

Because of the importance of including ethical considerations in planning efforts for pandemic influenza, in February 2005 the Centers for Disease Control and Prevention requested that the Ethics Subcommittee of the Advisory Committee to the Director develop guidance that would serve as a foundation for decision making in preparing for and responding to pandemic influenza. Specifically, the ethics subcommittee was asked to make recommendations regarding ethical considerations relevant to decision making about vaccine and antiviral drug distribution prioritization and development of interventions that would limit individual freedom and create social distancing. The ethics subcommittee identified a number of general ethical considerations including identification of clear goals for pandemic planning, responsibility to maximize preparedness, transparency and public engagement, sound science, commitment to the global community, balancing individual liberty and community interests, diversity in ethical decision making, and commitment to justice. These general ethical considerations are applied to the issues of vaccine and antiviral drug distribution and use of community mitigation interventions.

Unusual health problems have been reported by Gulf War (GW) veterans, but no single etiology has been linked to these illnesses. This study was conducted to determine the association between self-reported GW deployment stressors and an illness defined by a combination of fatigue, mood-cognition, and musculoskeletal symptoms. A total of 1002 GW veterans from this cross-sectional survey of four Air Force units completed a self-administered questionnaire that asked about symptoms, demographic and military characteristics, and stressors during deployment. Severe and mild-moderate illness was positively associated with self-reports of pyridostigmine bromide use, insect repellent use and belief in a threat from biological or chemical weapons. Injuries requiring medical attention were only associated with severe illness. These results suggest a link between self-reported chemical, emotional, and physical exposures, and GW veterans' illness. Further research is needed to determine physiological and psychological mechanisms through which such stressors could have contributed to this symptom complex.

Results of several studies suggest that either a reduction in the serum level of total cholesterol level or a persistently low cholesterol level may be associated with an increase in violent deaths. Although there are several possible explanations for these observations, it has been suggested that the cholesterol level could influence various behaviors. We therefore examined the cross-sectional relation of several psychologic characteristics, assessed by the Diagnostic Interview Schedule and the Minnesota Multiphasic Personality Inventory, to levels of total cholesterol, high-density lipoprotein cholesterol, and triglycerides among 3,490 men aged 31-45 years who were examined in 1985-1986. (All men had served in the US Army between 1965 and 1971). Compared with that of other men, the mean total cholesterol level was 5 mg/dl higher among 697 men diagnosed with generalized anxiety disorder (possibly because of increased catecholamine levels) and 7 mg/dl lower among 325 men with antisocial personality disorder (p < 0.01 for each association). These differences could not be attributed to education, relative weight, cigarette smoking, use of various medications, or other potential confounders. In contrast, cholesterol levels were not significantly associated with major depression or hostility; levels of high-density lipoprotein cholesterol and triglycerides were not related to any diagnosis. If the serum level of total cholesterol is found to be predictive of antisocial personality disorder in longitudinal analyses, this association may have implications for cholesterol-lowering recommendations.

Deployment to the Gulf War is associated with a range of mental health outcomes more than 10 years after deployment.
