Prevalence of undiagnosed diabetes and abnormalities of carbohydrate metabolism in a U.S. Army population.
OBJECTIVE: The Third National Health and Nutrition Examination Survey (NHANES III) reported that 4.3-6.3% of adult Americans have undiagnosed diabetes. 15.6% have impaired glucose tolerance, and 10.1% have impaired fasting glucose. By design, NHANES III excluded people in the U.S. military. The purpose of this study was to determine the prevalence of undiagnosed diabetes, impaired glucose tolerance, and impaired fasting glucose among U.S. Army soldiers. RESEARCH DESIGN AND METHODS: A 2-h, 75-g oral glucose tolerance test was performed on a prospective, consecutive sample of 625 asymptomatic soldiers presenting to a U.S. Army medical clinic for physical examinations. Age of subjects was 32 +/- 9 years (mean +/- SD), and 81.0% of subjects were male. BMI was 26.2 +/- 3.7 kg/m2. Race/ethnicity categories included Caucasian (54.4%), African-American (24.4%), Hispanic (17.4%), and other (3.7%). A family history of diabetes was reported by 25.4% of the subjects, and the number of exercise sessions per week was 4.0 +/- 1.5. RESULTS: The prevalence of undiagnosed diabetes was 3 of 625 (0.5%) (95% CI, 0.1-1.4): impaired glucose tolerance, 11 of 598 (1.8%) (0.9-3.3); and impaired fasting glucose 6 of 585 (1.0%) (0.4-2.2). CONCLUSIONS: In this low-diabetes risk U.S. Army population, the prevalence of undiagnosed diabetes, impaired glucose tolerance, and impaired fasting glucose were 0.5, 1.8, and 1.0%, respectively. The prevalence rates found in this study are approximately one-tenth of those found in NHANES III.
Expression of a 26S proteasome ATPase subunit, MS73, in muscles that undergo developmentally programmed cell death, and its control by ecdysteroid hormones in the insect Manduca sexta.
MS73, an ATPase regulatory subunit of the 26S proteasome in the moth Manduca sexta, is shown to be expressed at a high level only in muscles that are undergoing developmentally programmed cell death, or which are destined to do so. The amount of MS73 is increased by more than two-fold just before death in each of three different muscles that die at different times, under different developmental controls. An ecdysteroid (moulting hormone) agonist, RH-5849, that prevents the occurrence of programmed cell death in two of these muscles also prevents the normally occurring rise in level of MS73 in these muscles. This evidence is consistent with a role for MS73 in programmed cell death.

Development of health surveillance in Togo, west Africa.
Since 1988, the Ministry of Health (MOH) of Togo, with technical assistance from CDC, has systematically adapted and strengthened its health information system (HIS) to enable improved monitoring of trends in diseases. The previous system had been hampered by complicated, lengthy reporting forms; incomplete and delayed receipt of reporting forms; absence of mortality reporting; slow, cumbersome manual compilation and analysis methods; and lack of standard case definitions. To simplify the adaptation process, the system was divided into three main activities: data collection, data compilation and analysis, and dissemination of reports and follow-up action. Public health authorities in Togo have built on existing strengths and successfully adapted the HIS to focus on national morbidity and mortality prevention priorities.
