A Synchronous Spin-Exchange Optically Pumped NMR-Gyroscope

Inertial navigation systems generally consist of timing, acceleration, and orientation measurement units. Although much progress has been made towards developing primary timing sources such as atomic clocks, acceleration and orientation measurement units often require calibration. Nuclear Magnetic Resonance (NMR) gyroscopes, which rely on continuous measurement of the simultaneous Larmor precession of two co-located polarized noble gases, can be configured to have scale factors that depend to first order only on fundamental constants. The noble gases are polarized by spin-exchange collisions with co-located optically pumped alkali-metal atoms. The alkali-metal atoms are also used to detect the phase of precession of the polarized noble gas nuclei. Here we present a version of an NMR gyroscope designed to suppress systematic errors from the alkali-metal atoms. We demonstrate rotation rate angle random walk (ARW) sensitivity of 16 $\mu \text{Hz}/\sqrt{\text{Hz}}$ and bias instability of $\sim$800 nHz

Associations of cardiorespiratory fitness and fatness with metabolic syndrome in rural women with prehypertension.

BACKGROUND: This study investigated the associations of fitness and fatness with metabolic syndrome in rural women, part of a recognized US health disparities group. METHODS: Fitness, percentage body fat, BMI, and metabolic syndrome criteria were assessed at baseline in 289 rural women with prehypertension, ages 40-69, enrolled in a healthy eating and activity community-based clinical trial for reducing blood pressure. RESULTS: Ninety (31%) women had metabolic syndrome, of which 70% were obese by BMI (≥30 kg/m²), 100% by percentage body fat (≥30%), and 100% by revised BMI standards (≥25 kg/m²) cited in current literature. Hierarchical logistic regression models, adjusted for age, income, and education, revealed that higher percentage body fat (P \u3c 0.001) was associated with greater prevalence of metabolic syndrome. Alone, higher fitness lowered the odds of metabolic syndrome by 7% (P \u3c 0.001), but it did not lower the odds significantly beyond the effects of body fat. When dichotomized into fit and unfit groups, women categorized as fat had lower odds of metabolic syndrome if they were fit by 75% and 59%, for percentage body fat and revised BMI, respectively. CONCLUSION: Among rural women with prehypertension, obesity and fitness were associated with metabolic syndrome. Obesity defined as ≥25 kg/m² produced results more consistent with percentage body fat as compared to the ≥30 kg/m² definition

Alone, higher fitness lowered the odds of metabolic syndrome by 7% (P \u3c 0.001), but it did not lower the odds significantly beyond the effects of body fat. When dichotomized into “fit” and “unfit” groups, women categorized as “fat” had lower odds of metabolic syndrome if they were “fit” by 75% and 59%, for percentage body fat and revised BMI, respectively. Conclusion. Among rural women with prehypertension, obesity and fitness were associated with metabolic syndrome. Obesity defined as ≥25 kg/m2 produced results more consistent with percentage body fat as compared to the ≥30 kg/m2 definition

Erratum to ‘‘Associations of Cardiorespiratory Fitness and Fatness with Metabolic Syndrome in Rural Women with Prehypertension’’

In the original paper, the authors discovered a computer coding error that resulted in 33 of the women’s ages being incorrectly recorded. All analyses were repeated for this paper using the corrected age dataset, as all our logistic regression analyses in the published paper were adjusted for age.The repeated analyses, using the corrected dataset, lead to minor changes that needed to be reported to the results in the published paper. These corrections did not change the conclusion of the published paper.The authors apologize for any inconvenience

Development and Assessment of a Patient-Centered Care Curriculum

The purpose of this paper is to chronicle the development and implementation of a pilot offering of the patient-centered care (PCC) curriculum sponsored by a partnership of schools of allied health and nursing and a local health care system. The objective of this interdisciplinary track is to increase the competency of allied health and nursing graduates to function in health care teams in both PCC and non-PCC hospital environments, thus improving the effectiveness of patient care. The elective track consists of two courses; a third course is under consideration. Students and faculty participating in the elective track were surveyed to assess their attitudes toward change and patient-centered care. Generally, participants believed that they could work well together but were not convinced of the viability of the PCC. Although the curriculum is still in its implementation stage and the nursing participation became minimal, this study aids in understanding opinions of nursing and allied health faculty and students regarding a new PCC curriculum
