    Abstract:

    BACKGROUND: To evaluate the effect of a dietary supplement containing polyunsaturated fatty acids, in association with Humulus lupulus extract, on the Quality of Sleep using the Leeds Sleep evaluation questionnaire (LSEQ) in subjects with moderate to severe Sleep disorders. METHODS: Randomized placebo-controlled trial, in a Population-based setting. Participants were adult patients 25 to 65 years old with a chronic primary insomnia who volunteered for the study. The tested intervention consisted of two soft gelatine capsules per day, containing either the dietary supplement (active group) or olive oil (placebo group) for a month. Subjects could also volunteer for two ancillary studies on melatonin and actigraphy. Evaluation criteria included i) perception of the Quality of Sleep at the end of treatment using the LSEQ questionnaire, ii) Sleep efficiency measured by one-week actigraphic movement measurement performed before and during the treatment in a subsample of subjects, iii) night melatonin and 6 sulfatoxymelatonin (aMT6S) urine rates in a subsample of subjects. RESULTS: The average of Leeds score was similar in both groups (p = 0.95). A marked improvement in the Quality of Sleep was observed in both placebo (62%) and active (65%) group (p = 0.52). The evolution of urinary melatonin, aMT6S, and of the Mel/aMT6S ratio showed no differences between the two groups. Sleep efficiency, as measured by actigraphy, improved similarly in both groups during the treatment period, from 72% to 76% and 75% in the active and placebo group respectively (p = 0.91). CONCLUSIONS: The dietary supplement had neither effect on the perceived Quality of Sleep, nor on the melatonin metabolism and Sleep-wake cycle. Trial registration: clinical trials.gov:NCT00484497.

  • Type D Personality as A Moderator of the Relationship Between Life Events and Quality of Sleep
    Chinese journal of clinical psychology, 2008
    Co-Authors: Liu Wen
    Abstract:

    Objective: To investigate the moderating effect of type D personality on the relationship between life events and Quality of Sleep. Methods: 350 college students were investigated with the following scales: Life Event Scale, Type D Personality Scale, and Pittsburgh Sleep Quality Index. Results: According to Sleep Quality in this investigation, there were 40% students with good Sleep Quality, middle 50%, and poor 8.8%(not including the missing data). The ratio of type D personality was 28.87%, and the effect of type D personality as a moderator of the relationship between life events and Quality of Sleep was significant. Conclusion: Generally, the Sleep Quality of the subjects is moderate. The ratio of type D personality is 28.87%. Type D personality moderates the relationship between life events and Quality of Sleep.

  • Stress and Quality of Sleep in undergraduate nursing students.
    Revista brasileira de enfermagem, 2020
    Co-Authors: Kézia Katiane Medeiros Da Silva, Milva Maria Figueiredo De Martino, Clarissa Maria Bandeira Bezerra, Ângela Monic Lima De Souza, Danila Maria Da Silva, Jacqueline Targino Nunes
    Abstract:

    to analyze the level of stress and Sleep Quality in nursing students according to terms of the nursing program. descriptive and cross-sectional research developed in a higher education institution in Northeastern Brazil on 167 students. We used data collection, sociodemographic information, and a scale for assessing stress and Sleep Quality in nursing students. we identified a statistically significant difference between domains of the stress scale and the terms of the undergraduate program, and between the Quality of Sleep and such terms such as as in the fourth and sixth semesters. different stress scores show that the semester which concerns students the most is the fifth. Quality of Sleep was deemed good for the first, third, fifth, seventh, and eighth semesters; and poor for the fourth and sixth terms.

  • Long-term Quality of Sleep after remifentanil-based anaesthesia: a randomized controlled trial
    British journal of anaesthesia, 2012
    Co-Authors: Manuel Wenk, Daniel M. Pöpping, Gordon Chapman, H. Grenda, Thomas Ledowski
    Abstract:

    Background Clinical and pre-clinical data agree that opioids disrupt Sleep architecture. Recently, remifentanil has been suggested to cause possible long-term disturbances of Sleep Quality. This randomized controlled clinical trial was designed to substantiate or refute a possible long-term effect of remifentanil on the Quality of Sleep. Methods One hundred patients undergoing elective surgery were randomized to receive either fentanyl or remifentanil-based anaesthesia. Before operation (T0) and 3 (T3) and 6 (T6) months after operation, the Quality of Sleep was assessed by the Pittsburgh Sleep Quality Index (PSQI). Results Overall, the Quality of Sleep for patients in the remifentanil or fentanyl group was not significantly different at any time point. Patients in the fentanyl group screened as good Sleepers before operation showed no differences across time course of the study in PSQI scores. In contrast, good Sleepers in the remifentanil group had significantly impaired Sleep Quality for at least 3 months after operation. Patients who were before operation screened as poor Sleepers showed no significant changes in PSQI scores at T3 and T6 in both groups. Conclusions The intraoperative use of remifentanil in a general patient population does not significantly alter the Quality of Sleep in the postoperative period. However, it may result in a significant reduction in the Quality of Sleep in patients before operation considered good Sleepers. These changes were not observed in the group of patients receiving fentanyl. The relevance of these findings in terms of patient recovery and Quality-of-life warrants further investigation.
