ObjectivesPostoperative delirium, associated with negative consequences including longer hospital stays and worse cognitive and physical outcomes, is frequently accompanied by sleep-wake disturbance. Our objective was to evaluate the efficacy and short-term safety of ramelteon, a melatonin receptor agonist, for the prevention of postoperative delirium in older patients undergoing orthopedic surgery.DesignA quadruple-masked randomized placebo-controlled trial (Clinical Trials.gov NCT02324153) conducted from March 2017 to June 2019.SettingTertiary academic medical center.ParticipantsPatients aged 65 years or older, undergoing elective primary or revision hip or knee replacement.InterventionRamelteon (8 mg) or placeboMeasurementsEighty participants were randomized to an oral gel cap of ramelteon or placebo for 3 consecutive nights starting the night before surgery. Trained research staff conducted delirium assessments for 3 consecutive days starting on postoperative day (POD) 0, after recovery from anesthesia, and on to POD2. A delirium diagnosis was based upon DSM-5 criteria determined by expert panel consensus.ResultsOf 80 participants, five withdrew consent (one placebo, four ramelteon) and four were excluded (four ramelteon) after randomization. Delirium incidence during the 2 days following surgery was 7% (5 of 71) with no difference between the ramelteon versus placebo: 9% (3 of 33) and 5% (2 of 38), respectively. The adjusted odds ratio for postoperative delirium as a function of assignment to the ramelteon treatment arm was 1.28 (95% confidence interval: 0.21–7.93; z-value 0.27; p-value = 0.79). Adverse events were similar between the two groups.ConclusionIn older patients undergoing elective primary or revision hip or knee replacement, ramelteon was not efficacious in preventing postoperative delirium. 相似文献

Confounding is widely recognized in settings where all variables are fully observed, yet recognition of and statistical methods to address confounding in the context of latent class regression are slowly emerging. In this study we focus on confounding when regressing a distal outcome on latent class; extending standard confounding methods is not straightforward when the treatment of interest is a latent variable. We describe a recent 1-step method, as well as two 3-step methods (modal and pseudoclass assignment) that incorporate propensity score weighting. Using simulated data, we compare the performance of these three adjusted methods to an unadjusted 1-step and unadjusted 3-step method. We also present an applied example regarding adolescent substance use treatment that examines the effect of treatment service class on subsequent substance use problems. Our simulations indicated that the adjusted 1-step method and both adjusted 3-step methods significantly reduced bias arising from confounding relative to the unadjusted 1-step and 3-step approaches. However, the adjusted 1-step method performed better than the adjusted 3-step methods with regard to bias and 95 % CI coverage, particularly when class separation was poor. Our applied example also highlighted the importance of addressing confounding—both unadjusted methods indicated significant differences across treatment classes with respect to the outcome, yet these class differences were not significant when using any of the three adjusted methods. Potential confounding should be carefully considered when conducting latent class regression with a distal outcome; failure to do so may results in significantly biased effect estimates or incorrect inferences. 相似文献

CONTEXT: Major depression affects about 25% of the patients who have Alzheimer disease and has serious adverse consequences for patients and caregivers. Results of prior antidepressant treatment studies have produced contradictory findings and have not fully assessed the benefits of depression reduction. OBJECTIVES: To assess the efficacy and safety of sertraline hydrochloride for the treatment of major depression in Alzheimer disease, and to evaluate the effect of depression reduction on activities of daily living, cognition, and nonmood behavioral disturbance. DESIGN: Randomized, placebo-controlled, parallel, 12-week, flexible-dose clinical trial with a 1-week, single-blind placebo phase. The study was conducted between January 1, 1998, and July 19, 2001. SETTING: University outpatient clinic. PARTICIPANTS: Forty-four outpatients who have probable Alzheimer disease and major depressive episodes. INTERVENTION: Sertraline hydrochloride, mean dosage of 95 mg/d, or identical placebo, randomly assigned. MAIN OUTCOME MEASURES: Response rate, Cornell Scale for Depression in Dementia, Hamilton Depression Rating Scale, Mini-Mental State Examination, Psychogeriatric Depression Rating Scale-activities of daily living subscale, and Neuropsychiatric Inventory to quantify patient behavior disturbance and caregiver distress. RESULTS: In the sertraline-treated group 9 patients (38%) were full responders and 11 (46%) were partial responders compared with 3 (20%) and 4 (15%), respectively, in the placebo-treated group (P =.007). The sertraline-treated group had greater improvements in the scores for the Cornell Scale for Depression in Dementia (P =.002) and Hamilton Depression Rating Scale (P =.01), and a statistical trend toward less decline in activities of daily living on the Psychogeriatric Depression Rating Scale-activities of daily living subscale (P =.07). There was no difference between the treatment groups in Mini-Mental State Examination (P =.22) or Neuropsychiatric Inventory (P =.32) ratings over time. When full responders, partial responders, and nonresponders were compared, full responders only, or full and partial responders had significantly better ratings on activities of daily living (P =.04), behavioral disturbance (P =.01), and caregiver distress (P =.006), but not on the Mini-Mental State Examination (P =.76). Safety monitoring indicated few differences in adverse effects between the 2 treatment groups. CONCLUSIONS: Sertraline is superior to placebo for the treatment of major depression in Alzheimer disease. Depression reduction is accompanied by lessened behavior disturbance and improved activities of daily living, but not improved cognition. 相似文献

Abtract Immunological activation of rat peritoneal mast cells induced a transient elevation in the intracellular concentration of cyclic AMP. Enhancement or suppression of this rise by appropriate adenosine analogues produced parallel changes in histamine secretion. However, pharmacological activation of the cell with a number of diverse ligands induced histamine release without any accompanying changes in cyclic AMP. Moreover, this release was modulated by adenosine analogues in identical fashion to IgE-directed ligands but again without affecting cyclic AMP. On the basis of these results, the possible role of cyclic AMP in the induction of histamine secretion is critically considered. 相似文献
