A prospective study of blood donations in healthy elderly persons

Iron stores were observed in 57 healthy elderly volunteers, between 63 and 77 years of age, who donated 5 units of blood over approximately 1 year. An equal number of nondonors who contributed approximately 7 mL of blood at each visit for iron status measurements only were seen at the same frequency as the donor population. At entrance to the study, iron stores in women and men averaged 724 and 875 mg, respectively. After five donations, mean iron stores dropped to 67 mg in women (n = 27) and 362 mg in men (n = 30); four women (15%) became iron deficient, while two (7%) developed iron deficiency anemia. Three men (10%) developed iron deficiency, but none were found to be anemic. Mean intakes of iron were 23.3 and 22.5 mg per day, respectively, for women and men. Iron intakes were adequate to meet iron requirements of nondonors, but they were not sufficient to halt the steady decrease in iron stores among the donor population, in whom iron absorption increased from approximately 5 percent at entrance to 14 percent at the time of the fifth donation. In summary, healthy elderly persons may contribute to the national blood resource; however, donations should probably be limited to less than five per year or donors should regularly take an iron supplement to preserve reasonable amounts of iron reserves.     

A comparison of the efficiency of surfactant contact lens cleaners in removing eyeliner adherent to various soft contact lenses

We compared the efficiency of removing cosmetic eyeliner deposits from soft contact lenses with a variety of surfactant cleaners. Four types of daily cleaners were used to clean two groups of soft contact lenses (Group 1 and Group 2 : FDA classification) contaminated with an eyeliner. The lenses were cleaned in a Clensatron 700CL Automatic Contact Lens Cleaning unit. The amount of lens contamination before and after cleaning was quantified by digitising a photograph of the lens surface. We found that: 1. the eyeliner was less likely to adhere to Group 2 lenses, 2. the efficiency of removing eyeliner was independent of the cleaning solutions we used; when contaminated, Group 2 lenses were generally easier to clean, 3. the Clensatron unit was not as efficient as digital rubbing in removing the eyeliner.

Reduced basal salivary cortisol in children with asthma and allergic rhinitis

Aim: Reduced basal cortisol is reported in allergic disease. We investigated if basal salivary cortisol levels were reduced in children with asthma or allergic rhinitis, controlling for inhaled corticosteroids (ICS) use. Methods: Morning and evening saliva of asthmatic children aged 7–12 years (n = 50) and that of controls (n = 52) were sampled. A total of 19 asthmatics and four controls had allergic rhinitis. Healthy children were controls without rhinitis. Of all, 14 asthmatic children used low, and 12 used moderate or high doses of ICS. Cortisol was analysed by radioimmunoassay. Results: Morning salivary cortisol median (95% CI) was lower in asthmatics (8.7 (7.1, 9.7)) compared with that in controls (10.4 (9.6, 11.8); p = 0.006), which was similar for evening cortisol levels. Regression analyses demonstrated that asthmatics using moderate or high doses of ICS had reduced morning salivary cortisol adjusted (for age and gender) odds ratio (aOR) (95% CI) (0.54 (0.37, 0.80); p = 0.002) and reduced evening cortisol aOR (0.09 (0.01, 0.6); p = 0.02) compared with that in healthy children. Asthmatics with rhinitis on no or low doses of ICS had reduced morning cortisol aOR (0.73 (0.56, 0.96); p = 0.02) compared with that in healthy children. Conclusion: Asthmatic children on moderate or high doses of inhaled corticosteroids had reduced salivary cortisol, but co‐morbidity of asthma and rhinitis was also associated with reduced cortisol levels.     

Geographic variations and temporal trends of Salmonella -associated hospitalization in the U.S. elderly, 1991-2004: A time series analysis of the impact of HACCP regulation

Background  

About 1.4 million Salmonella infections, a common food-borne illness, occur in the U.S. annually; the elderly (aged 65 or above) are most susceptible. In 1997, the USDA introduced the Pathogen Reduction and Hazard Analysis and Critical Control Points Systems (PR/HACCP) which demands regular Salmonella testing in various establishments processing meat products, such as broiler chickens. Impact evaluations of PR/HACCP on hospitalizations related to Salmonella are lacking.
