Background. In this pilot study, the authors aimed to examine the implementation of standing desks on classroom performance and behavior. They also examined how the standing desks affected in-class physical activity and body mass index. Methods. Eight sixth graders from Hope Lutheran elementary school participated in the study (age 11.3 ± 0.5 years). Baseline and 8-month postintervention measures were step counts using (W4L Classic pedometers), height, weight, and behavioral markers. Results. Data showed that there were no statistically significant changes in the participants’ body mass index (19.4 kg/m2 vs 19.3 kg/m2), step counts (1886 steps vs 2248 steps), and behavioral markers including classroom management, concentration, and discomfort. Height and weight changes were significant and are attributed to the normal growth rate associated with the age of the participants (146.8 cm vs 151.8 cm, P < .0001; 41.4 kg vs 44.5 kg, P > .0007). Conclusions. It is feasible to integrate standing desks into a classroom without negative effects. Although the authors observed over a 19% increase in pedometer activity, it was not statistically significant. This highlights the importance for larger experimental groups and the use of more advanced physical activity tracking and body composition technologies.
On the basis of this data set of participating institutions in Florida, several areas in the care of patients with non–small-cell lung cancer were identified as targets for future quality improvement efforts.
Background and Purpose —The National Institutes of Health Stroke Scale (NIHSS) is accepted widely for measuring acute stroke deficits in clinical trials, but it contains items that exhibit poor reliability or do not contribute meaningful information. To improve the scale for use in clinical research, we used formal clinimetric analyses to derive a modified version, the mNIHSS. We then sought to demonstrate the validity and reliability of the new mNIHSS. Methods —The mNIHSS was derived from our prior clinimetric studies of the NIHSS by deleting poorly reproducible or redundant items (level of consciousness, face weakness, ataxia, dysarthria) and collapsing the sensory item into 2 responses. Reliability of the mNIHSS was assessed with the certification data originally collected to assess the reliability of investigators in the National Institute of Neurological Disorders and Stroke (NINDS) rtPA (recombinant tissue plasminogen activator) Stroke Trial. Validity of the mNIHSS was assessed with the outcome results of the NINDS rtPA Stroke Trial. Results —Reliability was improved with the mNIHSS: the number of scale items with poor κ coefficients on either of the certification tapes decreased from 8 (20%) to 3 (14%) with the mNIHSS. With the use of factor analysis, the structure underlying the mNIHSS was found identical to the original scale. On serial use of the scale, goodness of fit coefficients were higher with the mNIHSS. With data from part I of the trial data, the proportion of patients who improved ≥4 points within 24 hours after treatment was statistically significantly increased by tPA (odds ratio, 1.3; 95% confidence limits, 1.0, 1.8; P =0.05). Likewise, the odds ratio for complete/nearly complete resolution of stroke symptoms 3 months after treatment was 1.7 (95% confidence limits, 1.2, 2.6) with the mNIHSS. Other outcomes showed the same agreement when the mNIHSS was compared with the original scale. The mNIHSS showed good responsiveness, ie, was useful in differentiating patients likely to hemorrhage or have a good outcome after stroke. Conclusions —The mNIHSS appears to be identical clinimetrically to the original NIHSS when the same data are used for validation and reliability. Power appears to be greater with the mNIHSS with the use of 24-hour end points, suggesting the need for fewer patients in trials designed to detect treatment effects comparable to rtPA. The mNIHSS contains fewer items and might be simpler to use in clinical research trials. Prospective analysis of reliability and validity, with the use of an independently collected cohort, must be obtained before the mNIHSS is used in a research setting.
The goal of health care is to provide high-quality care at an affordable cost for its patients. However, the population it serves has changed dramatically since the popularization of hospital-based health care. With available new technology, alternative health care delivery methods can be designed and tested. This study examines scalable office-based health care for small business, where health care is delivered to the office floor. This delivery was tested in 18 individuals at a small business in Minneapolis, Minnesota. The goal was to deliver modular health care and mitigate conditions such as diabetes, hyperlipidaemia, obesity, sedentariness and metabolic disease. The modular health care system was welcomed by employees – 70% of those eligible enrolled. The findings showed that the modular health care deliverable was feasible and effective. The data demonstrated significant improvements in weight loss, fat loss and blood variables for at risk participants. This study leaves room for improvement and further innovation. Expansion to include offerings such as physicals, diabetes management, smoking cessation and prenatal treatment would improve its utility. Future studies could include testing the adaptability of delivery method, as it should adapt to reach rural and under-served populations.
