What's a Pregnant Woman to Eat? A Review of Current USDA Dietary Guidelines and MyPyramid

The purpose of this article is to clarify the nutritional recommendations for pregnant women in light of the new Food Guide Pyramid, known as "MyPyramid," along with the Dietary Guidelines for Americans 2005 and recommendations by the Institute of Medicine. The differences between the Food Guide Pyramid (introduced in 1992) and the more recent, color-coded MyPyramid (introduced in 2005) are discussed. A list of nutritional recommendations for pregnant women is presented, which may serve as a reference for practitioners when counseling pregnant women.     

Continuing education module: postpartum maternal health care in the United States: a critical review

Postpartum maternal health care is a neglected aspect of women's health care. This neglect is evident in the limited national health objectives and data related to maternal health. Missed opportunities for enhancing the health care of postpartum women occur in the scope of routine postpartum care. Differing perceptions of maternal needs between nurses and new mothers also contribute to inadequate health care. Therefore, collecting national data on postpartum maternal morbidity, reforming postpartum care policies, providing holistic and flexible maternal health care, encouraging family support and involvement in support groups, and initiating educational programs are recommended. Further research is needed on issues related to postpartum maternal health.     

Optimization of Maximal Rate of Heart Rate Increase Assessment in Runners

Purpose: Correlations between fatigue-induced changes in exercise performance and maximal rate of heart rate (HR) increase (rHRI) may be affected by exercise intensity during assessment. This study evaluated the sensitivity of rHRI for tracking performance when assessed at varying exercise intensities. Method: Performance (time to complete a 5-km treadmill time-trial [5TTT]) and rHRI were assessed in 15 male runners following 1 week of light training, 2 weeks of heavy training (HT), and a 10-day taper (T). Maximal rate of HR increase (measured in bpm·s^?1) was the first derivative maximum of a sigmoidal curve fit to HR data recorded during 5 min of running at 8 km·h^?1 (rHRI_8km·h^?1), and during subsequent transition to 13 km·h^?1 (rHRI_{8–13km·h^?1}) for a further 5 min. Results: Time to complete a 5-km treadmill time-trial was likely slower following HT (effect size ± 90% confidence interval = 0.16 ± 0.06), and almost certainly faster following T (–0.34 ± 0.08). Maximal rate of HR increase during 5 min of running at 8 km·h^?1 and rHRI_{8–13km·h^?1} were unchanged following HT and likely increased following T (0.77 ± 0.45 and 0.66 ± 0.62, respectively). A moderate within-individual correlation was found between 5TTT and rHRI_8km·h^?1 (r value ± 90% confidence interval = –.35 ± .32). However, in a subgroup of athletes (n = 7) who were almost certainly slower to complete the 5TTT (4.22 ± 0.88), larger correlations were found between the 5TTT and rHRI_8km·h^?1 (r = –.84 ± .22) and rHRI_{8–13km·h^?1} (r = –.52 ± .41). Steady-state HR during rHRI assessment in this group was very likely greater than in the faster subgroup (≥ 1.34 ± 0.86). Conclusion(s): The 5TTT performance was tracked by both rHRI_8km·h^?1 and rHRI_{8–13km·h^?1}. Correlations between rHRI and performance were stronger in a subgroup of athletes who exhibited a slower 5TTT. Individualized workloads during rHRI assessment may be required to account for varying levels of physical conditioning.     

Education Collections as Museum Collections

Museum education collections are inarguably a part of a museum's actual collection, just as are the research/permanent collections. However, past practices indicate that education collections are typically not given equal stature in museological terms. This paper argues that techniques and practices used with research/permanent collections should be applied to education collections, a viewpoint that has not yet been readily embraced. Several methods are addressed for upgrading an education collection to a level similar to a museum's permanent collection. The Lubbock Lake Landmark's education collection serves as a case study to demonstrate the need for the application of proper museological techniques to conform to best practices. A scope of collection was created, preventive conservation techniques were applied, a gap analysis was performed, and legal issues concerning the education collection were addressed.
