Using simulation technology for undergraduate nursing education.

As simulation technology is rapidly expanding, nursing programs are making large investments in this technology, which has great potential for undergraduate nursing programs. Unfortunately, this potential is underestimated and underused. With simulation technology, undergraduate students can gain and improve skills in a safe, non-threatening, experiential environment that also provides opportunities for decision making, critical thinking, and team building. This article describes how to use simulation technology to enhance undergraduate nursing education. The process for simulation technology instruction, leveling content from simple to complex, and faculty resources are discussed. An example of a simulation program is included.

Effects of exercise on bone density, balance, and self-efficacy in older women.

The effects of weighted vest walking and strength-training exercises on bone mineral density (BMD), balance, strength, and self-efficacy were tested in older women. Eighteen women, age 69.2 +/- 3.5 years, were randomly assigned to an exercise group (EG) (n = 9), or a sedentary control group (CG) (n = 9). The EG participated in 32 weeks (three 1-h sessions/week) of supervised strength training and walking, stair climbing, and balance exercises while wearing weighted vests. The CG did not exercise. All women took Ca2+ and vitamin D during the study period. Measures included 1) BMD of the hip and lumbar spine measured by dual-energy X-ray absorptiometry, 2) strength, 3) balance, and 4) scores on a self-efficacy instrument. The EG had significant improvements in bone density of the femoral neck and balance and a significant weight loss (P < 0.05). There were no changes in self-efficacy in either group.

The effects of endurance exercise and vitamin E on oxidative stress in the elderly.

To examine the effects of exercise and vitamin E supplementation on oxidative stress in older adults, 59 participants, age 76.3 +/- 4.2 years, were randomly assigned to 1 of 4 groups: an exercise group taking placebos (EGP) or vitamin E (EGE) or a sedentary group taking placebos (SGP) or vitamin E (SGE). Measures included weight, VO2max, blood pressure (BP), and serum concentrations of vitamin E and lipid hydroperoxide (LOOH). At the end of the 16-week trial, the EGP and EGE had significant increases in VO2max and significant decreases in resting BP, weight, and LOOH concentrations (P < 0.05). The SGE had significant decreases in LOOH and BP (P < 0.05). There were no significant changes in the SGP (P > 0.05). The results suggest that endurance exercise in combination with vitamin E reduces oxidative stress, improves aerobic fitness, and reduces BP and weight in older adults. Even sedentary participants who take vitamin E may reduce oxidative stress and lower BP.
