ABSTRACT

The Air Force Health Study (AFHS) is perhaps the most thorough longitudinal examination of both the health of military personnel and the health effects of herbicide exposure ever conducted. Data were collected through comprehensive physical examinations, questionnaires, and other records at six time points over a 20-year period; 2,758 subjects participated in at least one examination cycle. Data collected during physical examinations included indices of health status overall and specific endpoints for each organ system. Questionnaire data included sociodemographic information, marital and fertility history, health habits, recreation activities, toxic substances exposure, and military experience. Biospecimens were collected at each examination cycle; serum was collected at all six examinations while other biospecimens, such as semen and whole blood, were collected at one time. More than 200 clinical laboratory tests and measures were performed, with more than 60 of these measured at all six cycles. The vast amount of electronic data and the more than 91,000 unaliquoted biospecimens contained in the repository offer unique opportunities for new research on understanding determinants of health. The Institute of Medicine is the custodian of the AFHS materials and conducted a pilot research program to facilitate new research using the materials. An expert committee issued requests for proposals, created a Web-based form for submissions, reviewed and evaluated potential research studies, and made data and biospecimens available to qualified researchers. This article summarizes the experience of this initiative.

ABSTRACT

Although many suicide prevention programs focus on youth suicides, data indicate the vast majority of suicides occur among adults (18-64 years). In 2005 New Mexico joined the Centers for Disease Control and Prevention's National Violent Death Reporting System, collecting data on suicides, homicides, and unintentional firearm fatalities to better inform state and national prevention programs. We utilized data collected by the New Mexico Violent Death Reporting System in its first 2 years of operation (2005 and 2006) in order to define the demographic patterns of adult suicides in the state and characterize risk factors. A total of 526 suicides occurred among adults during this time, with the majority being male (78.5%) and White non-Hispanic (56.7%). The highest incidence was in adults between 45 and 54 years (28.1%). Firearms were the most commonly used mechanism, and "current depressed mood" the most commonly identified risk factor. High rates of adult suicide indicate the need for targeted prevention programs.

ABSTRACT

Many bacterial species function as both commensals and pathogens; we used this dual nature to develop a high-throughput molecular epidemiological approach to identifying bacterial virulence genes. We applied our approach to Group B Streptococcus (GBS). Three representative commensal and one invasive GBS isolates were selected as tester strains from a population-based collection. We used microarray-based comparative genomic hybridization to identify open reading frames (ORFs) present in two sequenced invasive strains, but absent or divergent in tester strains. We screened 23 variable ORFs against 949 GBS isolates using a GBS Library on a Slide (LOS) microarray platform. Four ORFs occurred more frequently in invasive than commensal isolates, and one appeared more frequently in commensal isolates. Comparative hybridization using an oligonucleotide microarray, combined with epidemiologic screening using the LOS microarray platform, enabled rapid identification of bacterial genes potentially associated with pathogenicity.
