Living arrangements and nutrient intakes of healthy women age 65 and older: a study in Manhattan, Kansas.

One hundred healthy women over age 65 were recruited for a study to determine differences in nutrient intakes by living arrangement and to examine the effect of demographic characteristics, health habits, and social contacts on nutrient intakes. There were significant differences (p < 0.05) in the mean intakes for calcium and riboflavin between women living alone and women living with a spouse. There were no significant differences in health habits by living arrangement, but women living alone were more likely to have fewer social contacts than women living with a spouse (x2 = 38.25; p < 0.001). Education, physical activity, and smoking were the most important predictors of nutrient intakes.

Consumption of caroltenoid-rich foods and central vision loss:a matched case-controlled study in Kansas.

The purpose of this study was to explore the association between consumption of carotenoid-rich foods and risk of central vision loss in 168 rural elders. Food consumption was estimated using a food frequency questionnaire. Median servings per week were used as the cut points for consumption levels. Odds ratios (OR) and 95% confidence intervals (CI) were calculated by using discordant pairs. High consumption of corn bread indicated significant association with central vision loss (OR 0.4; 95% CI 0.2, 0.9). Insignificant inverse associations were observed for seven other foods and the summary index of all selected foods. Prospective studies are needed to further evaluate the potential protective influence of carotenoid-rich foods on central vision loss among older adults.

An infestation of 2,055 brown recluse spiders (Araneae: Sicariidae) and no envenomations in a Kansas home: implications for bite diagnoses in nonendemic areas.

During a 6-mo period, 2,055 brown recluse spiders, Loxosceles reclusa Gertsch and Mulaik, were collected in a 19th-century-built, currently occupied home in Lenexa, KS. We conservatively estimate that at least 400 of these spiders were large enough to cause envenomation. Additional collections from more typically infested homes in Missouri and Oklahoma in 2001 yielded 45 and 30 brown recluse spiders, respectively. Despite these infestations, no envenomations of the inhabitants of these three homes occurred. Considering the levels of infestations with no bites in the homes presented here, nonendemic areas in the United States, which typically lack recluse spider populations and have had zero to few verified specimens of the spider, do not have sufficient numbers of brown recluse spiders to make envenomation a likely scenario. Despite this, physicians from nonendemic recluse areas often diagnose brown recluse bites which, therefore, are unlikely to be correct.

Economic feasibility of no-tillage and manure for soil carbon sequestration in corn production in northeastern Kansas.

This study examined the economic potential of no-tillage versus conventional tillage to sequester soil carbon by using two rates of commercial N fertilizer or beef cattle manure for continuous corn (Zea mays L.) production. Yields, input rates, field operations, and prices from an experiment were used to simulate a distribution of net returns for eight production systems. Carbon release values from direct, embodied, and feedstock energies were estimated for each system, and were used with soil carbon sequestration rates from soil tests to determine the amount of net carbon sequestered by each system. The values of carbon credits that provide an incentive for managers to adopt production systems that sequester carbon at greater rates were derived. No-till systems had greater annual soil carbon gains, net carbon gains, and net returns than conventional tillage systems. Systems that used beef cattle manure had greater soil carbon gains and net carbon gains, but lower net returns, than systems that used commercial N fertilizer. Carbon credits would be needed to encourage the use of manure-fertilized cropping systems.
