Effects of aromatherapy with essential oil massage on the sleep quality of critical care nurses: A randomized controlled trial.

The purpose of this study was to explore the effectiveness of an essential oil massage on the sleep quality of the critical care nurses. A randomized controlled trial with single blind was conducted. A total of 112 critical care nurses were recruited. Participants were randomly allocated to either the experimental or control group. Only the experimental group received four sessions consisting of a lavender essential oil massage. The results of this study revealed that the overall subjective sleep quality and objective sleep parameters did not reach a significant difference between the two groups before and after the intervention, but a progressive the subjective sleep quality score reduction was observed in the experimental group. The findings of this study might provide information to critical care nurses who are under high pressure to find the optional alternative way of managing their self-sleep health by employing safe and convenient alternatives through aromatherapy.

The effects of Tai-Chi in conjunction with thera-band resistance exercise on functional fitness and muscle strength among community-based older people.

AIMS AND OBJECTIVES: The aim of this study was to investigate the effects of Tai-Chi in conjunction with thera-band resistance exercise on functional fitness and muscle strength in community-based older people. BACKGROUND: Tai-Chi is known to improve functional fitness in older people. Tai-Chi is usually performed with free hands without resistance training and usually focuses on training lower limbs. To date, no study has examined the use of Tai-Chi in conjunction with thera-band resistance exercise in this population. DESIGN: Cluster randomised trial design. METHODS: Older people at six senior day care centres in Taiwan were assigned to thera-band resistance exercise or control group using a cluster randomisation. The thera-band resistance exercise group (n = 48) received sixty minute thera-band resistance exercise twice weekly for a period of 16 weeks. The control group (n = 47) underwent routine activities in the day care centre, receiving no Tai-Chi or resistance exercise. RESULTS: After receiving the thera-band resistance exercise, intervention participants displayed a significant increase in muscle strength of upper and lower extremities. Significant improvements were recorded on most measures of the Senior Fitness Test, with the exception of the chair-stand and back-scratch test. CONCLUSION: Thera-band resistance exercise has the potential to improve functional fitness and muscle strength in community-based older people. RELEVANCE TO CLINICAL PRACTICE: Thera-band resistance exercise potentially offers a safe and appropriate form of physical activity that nursing staff can easily incorporate into the daily routine of older people in day care centres, potentially improving functional performance and muscle strength.

[The HPLC fingerprint analysis of Fructus citri].

OBJECTIVE: To study and establish the fingerprint of raw Fructus Citri by phased high performance liquid chromatography. METHOD: The chromatographic conditions were as follows: a Kromasil C18 column was used; the mobile phase was composed of methanol and acetic-water(3.1:100, v/v) with gradient elution; the flow rate was 1.0 ml/min and the UV absorbance detection was set at 284 nm. RESULT: Under the selected chromatographic conditions, good HPLC fingerprints of Fructus Citri were obtained. CONCLUSION: Quality of raw Fructus Citri can be controlled effectively by HPLC fingerprint.
