    Objective To investigate sleep quality of the elderly in cadre's sanitarium,and to provide the strategies of health care for improving sleep quality.Methods 140 cases of the elderly whose ages were older than or equal to 60 in cadre's sanitarium were selected by cluster sampling method.Their sleep quality were investigated with the Pittsburgh sleep quality index(PSQI).Results(1)The average score of PSQI was 7.03±4.22.46.4% of the elderly who had sleep problems.(2)The older women's sleep quality were generally poorer than the men's sleep(P0.05).Sleep quality had significantly negative correlation with age(P0.05).The aged people with higher educational level had better sleep quality(P0.05).Conclusion Sleep quality of the elderly in cadre's sanitarium is not optimistic.It is suggested that more countermeasures should be applied in order to improve their sleep quality.

    In this study, we analyze the effect of a recliner chair with rocking motions on sleep quality of naps using automated sleep scoring and spindle detection models. The quality of sleep corresponding to the two rocking motions was measured quantitatively and qualitatively. For the quantitative evaluation, we conducted a sleep parameter analysis based on the results of the estimated sleep stages obtained on the brainwave and spindle estimation, and a sleep survey assessment from the participants was analyzed for the qualitative evaluation. The analysis showed that sleep in the recliner chair with rocking motions positively increased the duration of the spindles and deep sleep stage, resulting in improved sleep quality.

    Objectives: As buprenorphine treatment and illicit buprenorphine use increase, many patients seeking buprenorphine treatment will have had prior experience with buprenorphine. Little evidence is available to guide optimal treatment strategies for patients with prior buprenorphine experience. We examined whether prior buprenorphine experience was associated with treatment retention and opioid use. We also explored whether type of prior buprenorphine use (prescribed or illicit use) was associated with these treatment outcomes. Methods: We analyzed interview and medical record data from a longitudinal cohort study of 87 individuals who initiated office-based buprenorphine treatment. We examined associations between prior buprenorphine experience and 6-month treatment retention using logistic regression models, and prior buprenorphine experience and any self-reported opioid use at 1, 3, and 6 months using nonlinear mixed models. Results: Most (57.4%) participants reported prior buprenorphine experience; of these, 40% used prescribed buprenorphine and 60% illicit buprenorphine only. Compared with buprenorphine-naïve participants, those with prior buprenorphine experience had better treatment retention (adjusted odds ratio [AOR] = 2.65, 95% CI = 1.05-6.70). Similar associations that did not reach significance were found when exploring prescribed and illicit buprenorphine use. There was no difference in opioid use when comparing participants with prior buprenorphine experience with those who were buprenorphine-naive (AOR = 1.33, 95% CI = 0.38-4.65). Although not significant, qualitatively different results were found when exploring opioid use by type of prior buprenorphine use (prescribed buprenorphine vs buprenorphine-naïve, AOR = 2.20, 95% CI = 0.58-8.26; illicit buprenorphine vs buprenorphine-naïve, AOR = 0.47, 95% CI = 0.07-3.46). Conclusions: Prior buprenorphine experience was common and associated with better retention. Understanding how prior buprenorphine experience affects treatment outcomes has important clinical and public health implications.
    Buprenorphine has been widely recommended for treatment of pain in rodents. We have previously documented that the recommended postoperative oral dose of buprenorphine in male Long-Evans rats, 0.5 mg/kg, is not as effective as the recommended parenteral dose of buprenorphine (0.05 mg/kg, s.c.) as an analgesic (21). In the series of experiments reported here, we compared: the analgesic effect of buprenorphine when prepared in two ways in the laboratory with that of a commercially available injectable solution of buprenorphine; the analgesic effect of buprenorphine in Long-Evans rats with that in Sprague-Dawley rats; and Long-Evans and Sprague-Dawley rats for development of pica, a commonly reported side effect of buprenorphine. We followed the pica experiment with assessment of the effectiveness of buprenorphine in establishing a conditioned flavor aversion. The results indicated that method of preparation did not result in any significant differences in the efficacy of injected buprenorphine. Strain of rat was not associated with a significant difference in the efficacy of buprenorphine. However, a significant strain difference was found in development of pica. Buprenorphine treatment was effective in inducing a conditioned flavor aversion. We concluded that the recommended oral dose of buprenorphine (0.5 mg/kg) is ineffective as an analgesic, and that this was not the result of method of preparation of the buprenorphine or strain of rat used. Furthermore, we concluded that buprenorphine treatment may induce gastrointestinal distress in both strains tested. The results reaffirm our previous conclusion that oral administration of buprenorphine at 0.5 mg/kg, despite the general recommendation, is not a reasonable treatment for postsurgical pain in rats.

    Implantable buprenorphine is an expensive alternative for patients on a stable dosage of transmucosal buprenorphine. Based on current research and guidance, implantable buprenorphine should not be used as initial treatment for opioid dependence or as a substitute for medication-assisted treatments other than transmucosal buprenorphine.

    Buprenorphine has been used internationally for the treatment of opioid use disorder (OUD) since the 1990s and has been available in the United States for more than a decade. Initial practice recommendations were intentionally conservative, were based on expert opinion, and were influenced by methadone regulations. Since 2003, the American crisis of OUD has dramatically worsened, and much related empirical research has been undertaken. The findings in several important areas conflict with initial clinical practice that is still prevalent. This article reviews research findings in the following 7 areas: location of buprenorphine induction, combining buprenorphine with a benzodiazepine, relapse during buprenorphine treatment, requirements for counseling, uses of drug testing, use of other substances during buprenorphine treatment, and duration of buprenorphine treatment. For each area, evidence for needed updates and modifications in practice is provided. These modifications will facilitate more successful, evidence-based treatment and care for patients with OUD.
