Dataset of The Relationship Between Postoperative Opioid Analgesia and Sleep Apnea Severity in Patients Undergoing Hip Arthroplasty: A Randomized, Controlled, Triple-Blinded Trial
<p>This the dataset related to the article entitled "he Relationship Between Postoperative Opioid Analgesia and Sleep Apnea Severity in Patients Undergoing Hip Arthroplasty: A Randomized, Controlled, Triple-Blinded Trial".</p> <p>Purpose: Residual postoperative pain after hip arthroplasty is usually treated with oral opioids. While classic opioids are associated with respiratory depression and worsening of sleep apnea, tramadol has been reported to preserve respiratory function. However, this has not been investigated in a prospective trial using respiratory polygraphy. This randomized controlled triple-blinded trial tested the hypothesis that postoperative treatment with oral opioids such as oxycodone would increase sleep apnea severity, measured with a respiratory polygraphy, compared with oral tramadol.<br> Patients and Methods: Sixty patients undergoing hip arthroplasty under spinal anesthesia with 15 mg isobaric bupivacaine 0.5% were randomized to receive postoperative pain treatment with either oral oxycodone (controlled-release 10 mg every 12 hours and immediate-release 5 mg every 4 hours as needed) or oral tramadol (controlled-release 100 mg every 8 hours and immediate-release 50 mg every 4 hours as needed). Respiratory polygraphy was performed on the first postoperative night. The primary outcome was the apnea-hypopnea index in the supine position. Secondary outcomes included the oxygen desaturation index, postoperative pain scores and intravenous morphine consumption.<br> Results: Mean supine apnea-hypopnea index on postoperative night 1 was 11.3 events.h−1 (95% confidence interval, 4.8–17.7) in the oxycodone group and 10.7 (4.6–16.8) events.h−1 in the tramadol group (p=0.89). There were no significant differences between the oxycodone and tramadol groups with respect to any secondary sleep-related or pain-related outcomes.<br> Conclusion: Oral oxycodone did not increase sleep apnea severity measured using respiratory polygraphy compared with oral tramadol on the first postoperative night after hip arthroplasty.</p>

Data for: Altered Circadian Rhythm, Sleep, and Rhodopsin 7-Dependent Shade Preference During Diapause in Drosophila Melanogaster
<p>To survive adverse environments, many animals enter a dormant state such as hibernation, dauer, or diapause. Various Drosophila species undergo adult reproductive diapause in response to cool temperatures and/or short day-length. While it is known that flies are less active during diapause, an in-depth understanding of diapause effects on circadian rhythms and sleep is lacking. Here we show that, in diapause-inducing conditions, Drosophila melanogaster exhibit altered circadian activity profiles, including a severely reduced morning activity peak and an advanced evening activity peak. Consequently, the flies have a single activity peak at a time similar to when non-diapausing flies have a siesta. Temperatures ≤15 °C, rather than short day-length, primarily drive the behavior. At cool temperatures, flies also rapidly enter a deep sleep state that lacks the sleep cycles of flies at higher temperatures and requires particularly high levels of stimulation for arousal. Furthermore, we show that at 18–25 °C, flies prefer to siesta in the shade, a preference that is virtually eliminated at 10 °C. Resting in the shade is driven by an aversion to blue light, sensed by rhodopsin 7 (Rh7) outside of the eyes. Flies at 10 ˚C show neuronal markers of elevated sleep pressure, including increased expression of Bruchpilot and elevated Ca2+ in the R5 ellipsoid body neurons. Therefore, sleep pressure might overcome blue light aversion. Thus at temperatures known to cause reproductive arrest, preserve germline stem cells, and extend lifespan, Drosophila melanogaster are prone to deep sleep and exhibit dramatically altered - yet rhythmic - daily activity patterns.</p>

Influence of young age microbiome on adult sleep behavior in D. Melanogaster
<p>There is growing evidence for the interaction between the gut microbiome and the brain. Several studies report strong correlations between the composition of the gut microbiome and various neurological diseases. Moreover, gut bacteria are shown to influence levels of neurotransmitters, e.g GABA, which are unbalanced in stress related disorders, such as anxiety and depression but also in in sleep disorders.</p> <p><em>Drosophila Melanogaster</em> is a powerful model organism for investigating the interaction between the microbiome and the brain. In addition to available genetic techniques, yielding germ free (axenic) flies and establishing gnotobiotic cultures is faster and easier with fruit flies compared to other model organisms. Moreover, <em>Drosophila</em> microbiome is much simpler in complexity, in contrast to the vertebrate microbiome.</p> <p>We investigated the significance of the young age microbiome on adult sleep behaviour in <em>Drosophila</em>. Our hypothesis was that differences in microbiome composition might elucidate the reason for the behavioral variability in resilience/vulnerability to sleep deprivation, amongst individuals with same genetic background. However, our results suggest that there is no/ minor effect of the <em>Drosophila </em>microbiome on sleep behaviour. </p> <p> </p>

Subjective sleep quality and sleep architecture in patients with migraine: a meta-analysis
<p>Objectives: Sleep disturbance is often associated with migraine. However, there is a paucity of research investigating objective and subjective measures of sleep in migraine patients. This meta-analysis aims to determine whether there are differences in subjective sleep quality measured using the Pittsburgh Sleep Quality Index (PSQI), and objective sleep physiology measured using polysomnography between adult and pediatric patients, and healthy controls.</p> <p>Methods: This review was pre-registered on PROSPERO (CRD42020209325). A systematic search of five databases (Embase, MEDLINE®, Global Health, APA PsycINFO, APA PsycArticles, last searched: 12/17/2020) was conducted to find case-controlled studies which measured polysomnography and/or PSQI in patients with migraine. Pregnant participants and those with other headache disorders were excluded. Effect sizes (Hedges' <i>g</i>) were entered into a random effects model meta-analysis. Study quality was evaluated with the Newcastle Ottawa Scale, and publication bias with Egger's regression test.</p> <p>Results: 32 studies were eligible, of which 21 measured PSQI and/MIDAS in adults, 6 measured PSG in adults and 5 in children. The overall mean study quality score was 5/9, and this did not moderate any of the results, and there was no risk of publication bias. Overall, adults with migraine had higher PSQI scores than healthy controls (<i>g</i>=0.75, <i>p</i> < .001, 95% confidence interval [95%CI]: 0.54 - 0.96). This effect was larger in those with chronic rather than episodic condition (<i>g</i>=1.03, <i>p </i>< .001, 95%CI: 0.37 - 1.01, <i>g </i>= 0.63, <i>p </i>< .001, 95%CI: 0.38 - 0.88 respectively). For polysomnographic studies, adults and children with migraine displayed a lower percentage of REM sleep (<i>g</i>=-0.22, <i>p</i> = 0.017, 95%CI: -0.41 - -0.04, <i>g</i> = -0.71, <i>p</i> = 0.025, 95%CI: -1.34 - -0.10 respectively) than controls. Pediatric patients displayed less total sleep time (<i>g</i>=-1.37, <i>p </i>= 0.039, 95%CI: -2.66 - -0.10), more wake (<i>g</i>=0.52, <i>p </i>< .001, 95%CI: 0.08 – 0.79) and shorter sleep onset latency (<i>g</i>=-0.37, <i>p </i>< .001, 95%CI: -0.54 - -0.21) than controls.</p> <p>Discussion: People with migraine have significantly poorer subjective sleep quality and altered sleep physiology compared to healthy individuals. Further longitudinal empirical studies are required to enhance our understanding of this relationship.</p>
