We explored the effects of acupressure training on older adults' sleep quality and cognitive function. Ninety older adults with impaired sleep quality were selected from screened volunteers and randomly divided into equal control and experimental groups; 82 completed the 1-year follow-up. Participants in the control group were given instructions on sleep health, while those in the experimental group received sleep health instructions plus individual and small group acupressure training sessions and support to practice the intervention on their own each day. All participants were assessed by trained assistants blind to study group allocation using Chinese versions of the Pittsburgh Sleep Quality Index, the Epworth Sleepiness Scale, the Mini-Mental State Examination, and four subscales from the revised Chinese version of the Wechsler Memory Scale, at baseline and at 3, 6, and 12 months. Repeated measures analysis of variance showed that acupressure training improved older adults' sleep quality and cognitive function, but the mediating effect of sleep on the relationship between acupressure training and cognitive function was not supported. Given the ease, simplicity, and safety of acupressure training observed with community-dwelling older adults in China, attempts should be made to replicate these preliminary positive findings with larger samples. © 2016 Wiley Periodicals, Inc.
Background: Given the limited effectiveness of pharmacological treatments in mitigating cognitive decline in individuals with mild cognitive impairment (MCI), there is a pressing need for developing effective non-pharmacological intervention programs to counteract MCI-related cognitive decline. Acupressure and cognitive training are safe and cost-effective; however, evidence of the effect of acupressure or the combined effect of acupressure and cognitive training on cognitive functions of older adults with MCI is limited.Objective: To evaluate both the individual and combined effects of acupressure and cognitive training on cognitive functions of older adults with MCI.Methods: One hundred and eighty older adults with MCI were recruited and randomly assigned to combined acupressure and cognitive training group (n = 45), acupressure group (n = 45), cognitive training group (n = 45), or control group (n = 45). Participants in the experimental groups received self-administered and group-based training sessions, while those in the control group received routine community education. The intervention lasted for 6 months. The cognitive functions of all the participants were assessed at multiple stages, including pre-intervention, at the end of the third and sixth months.Results: One hundred and fifty-one participants completed the study, and all participants analyzed in intervention groups completed at least 85% of all practice sessions recommended. Repeated measures analysis of variance of the scores of Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) at different time points among the four groups revealed that the group effect, time effect, and interaction effect were all significant (p < 0.01). Pairwise comparisons with Bonferroni correction showed that the scores of MMSE and MoCA in acupressure group, cognitive training group, and combined group were significantly raised compared with control group (p < 0.01). Compared with acupressure or cognitive training groups, the scores of MMSE and MoCA in combined group were significantly higher (p < 0.05). The scores of MMSE and MoCA in acupressure group had no significant differences with those in cognitive training group (p > 0.05).Conclusion: Acupressure and cognitive training both could improve the cognitive functions of older adults with MCI, and when used together, the effects were enhanced.Clinical Trial Registration: This study was registered in the Chinese Clinical Trial Registry (No.ChiCTR2100049955).
Background: This study explored the differences, correlation, and consistency between blood glucose levels measured using an arterial blood gas analyzer and a rapid blood glucose meter in critically ill patients.Methods: A total of 73 critically ill patients admitted to the Department of Critical Care Medicine, from October to December 2016 were enrolled in this study. The patient's arterial blood glucose was measured by arterial blood gas analyzer, while peripheral blood glucose was measured by a rapid blood glucose meter (via the non-infusion limb). The correlation between indicators was analyzed using the linear regression model. Bland-Altman was performed to evaluate the agreement of the two methods for measuring blood glucose. P<0.05 was considered statistically significant. Results:The blood glucose values measured using the arterial blood gas analyzer was significantly different from the values obtained using the rapid blood glucose meter (P=0.000). Regression analysis showed that R2 was 0.857 and β was 0.324 (P=0.000). Bland-Altman plot analysis showed that arterial blood glucose values obtained using the arterial blood gas analyzer were higher than the peripheral blood glucose values obtained using the rapid blood glucose meter on the non-infused limb, with 2.74% of dots lying outside the 95% limit of agreement and the maximum absolute value (2.30 mmol/L) of blood glucose difference within the limit of agreement. The blood glucose levels measured using the two different methods showed good agreement. Conclusions:The difference in blood glucose values measured using the two different measurement methods was statistically significant, but the maximum absolute value (2.30 mmol/L) of blood glucose difference within the limit of agreement, which is acceptable in the clinical setting. In clinical care, it is not necessary to repeat a measure of the patient's capillary blood glucose (CBG) using the rapid blood glucose meter after the blood glucose levels have been measured with the arterial blood gas analyzer, thereby reducing the associated pain and inconvenience for the patients.
