The Impact

Objective To determine the impact of treatment for patients with nasal obstruction secondary to allergic rhinitis (AR) and nasal septal deviation (NSD) on sleep quality. Data Sources Primary studies were identified though PubMed, Scopus, Cochrane Library, and Web of Science. Review Methods A systematic review was performed by querying databases for articles published through August 2020. Studies were included that reported on objective sleep parameters (apnea-hypopnea index) and sinonasal and sleep-specific patient-reported outcome measures: Rhinoconjunctivitis Quality of Life Questionnaire, Nasal Obstruction Symptom Evaluation, Epworth Sleepiness Scale (EpSS), and Pittsburgh Sleep Quality Index (PSQI). Results The database search yielded 1414 unique articles, of which 28 AR and 7 NSD studies were utilized for meta-analysis. A total of 9037 patients (8515 with AR, 522 with NSD) were identified with a mean age of 35.0 years (35.3 for AR, 34.0 for NSD). Treatment for AR and NSD significantly improved subjective sleep quality. For AR, the EpSS mean difference was −1.5 (95% CI, –2.4 to –0.5; P = .002) and for the PSQI, –1.7 (95% CI, –2.1 to –1.2; P < .00001). For NSD, the EpSS mean difference was −3.2 (95% CI, –4.2 to –2.2; P < .00001) and for the PSQI, –3.4 (95% CI, –6.1 to –0.6; P = .02). Conclusion Subjective sleep quality significantly improved following treatment for AR and NSD. There were insufficient data to demonstrate that objective metrics of sleep quality similarly improved.

PurposeDifferent dietary supplements aimed at improving sleep quality are available on the market, but there has not been a comprehensive review to evaluate the efficacy of these dietary supplements on subjective sleep quality. We aimed to summarise up-to-date research evidence and to identify the types of dietary supplement that improve subjective sleep quality.MethodsMultiple databases (Ovid Emcare, Ovid MEDLINE (R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations and APA PsycInfo) were used for searching papers published until August 2020. The changes in sleep quality indices, intervention duration and sample size were extracted from every paper. To analyse the effect of dietary supplements on sleep quality, a random effects model with mean difference (MD) and 95% CI was adopted. The heterogeneity across studies was measured by I2 statistics. The quality of included studies was evaluated by Cochrane’s risk of bias tool.ResultsThirty-one randomised controlled trials of dietary supplements were included. Subjective sleep quality was significantly improved by supplementation of amino acids (MD −1.27, 95% CI −2.35 to –0.20; I2=0%), melatonin (MD −1.21, 95% CI −2.17 to –0.24; I2=79%) and vitamin D (MD −1.63, 95% CI −3.15 to –0.10; I2=85%). Although not all studies provided adequate data for meta-analysis, we also discussed how magnesium, zinc, resveratrol and nitrate supplementation may improve sleep quality.ConclusionsAmino acids, vitamin D and melatonin supplements were significantly beneficial to improve sleep quality. However, high heterogeneity and wide confidence levels were observed in vitamin D and melatonin. Further research on the effect of magnesium, zinc, resveratrol and nitrate supplementation on improving sleep quality is required.

ABSTRACT Introduction Traumatic brain injury (TBI) or concussion is a known risk factor for multiple adverse health outcomes, including disturbed sleep. Although prior studies show adverse effects of TBI on sleep quality, its compounding effect with other factors on sleep is unknown. This meta-analysis aimed to quantify the effects of TBI on subjective sleep quality in the context of military status and other demographic factors. Materials and Methods A programmatic search of PubMed database from inception to June 2020 was conducted to identify studies that compared subjective sleep quality measured using Pittsburgh Sleep Quality Index (PSQI) in individuals with TBI relative to a control group. The meta-analysis included group-wise standard mean difference (SMD) and 95% CI. Pooled means and SDs were obtained for TBI and non-TBI groups with and without military service, and meta-regression was conducted to test for group effects. Exploratory analysis was performed to test for the effect of TBI, non-head injury, military status, sex, and age on sleep quality across studies. Results Twenty-six articles were included, resulting in a combined total of 5,366 individuals (2,387 TBI and 2,979 controls). Overall, individuals with TBI self-reported poorer sleep quality compared to controls (SMD = 0.63, 95% CI: 0.45 to 0.80). Subgroup analysis revealed differences in the overall effect of TBI on PSQI, with a large effect observed in the civilian subgroup (SMD: 0.80, 95% CI: 0.57 to 1.03) and a medium effect in the civilian subgroup with orthopedic injuries (SMD: 0.40, 95% CI: 0.13 to 0.65) and military/veteran subgroup (SMD: 0.43, 95% CI: 0.14 to 0.71). Exploratory analysis revealed that age and history of military service significantly impacted global PSQI scores. Conclusions Poor sleep quality in TBI cohorts may be due to the influence of multiple factors. Military/veteran samples had poorer sleep quality compared to civilians even in the absence of TBI, possibly reflecting unique stressors associated with prior military experiences and the sequelae of these stressors or other physical and/or psychological traumas that combine to heightened vulnerability. These findings suggest that military service members and veterans with TBI are particularly at a higher risk of poor sleep and its associated adverse health outcomes. Additional research is needed to identify potential exposures that may further heighten vulnerability toward poorer sleep quality in those with TBI across both civilian and military/veteran populations.

Self Compassion

Poor sleep quality is highly prevalent in modern societies and negatively linked to various health outcomes. While previous research has demonstrated preliminary evidence for self-compassion as a tool for improving sleep quality, this review provides a meta-analysis of respective published and unpublished results of our own research group using German samples. A total of nine studies are included (N = 956 participants), consisting of both correlational and experimental data. Across these studies, there was a medium correlation between self-compassion and subjective sleep quality, r = 0.303, 95% CI (0.244; 0.360). In three experimental studies, a small increase in participants’ self-reported sleep quality emerged, in comparison to control conditions, Hedges’ s g = 0.484, 95% CI (0.148; 0.821). Limitations on study level concern both the small sample sizes and short-term analyses of intervention effects. As a conclusion, this review supports both the correlational and causal relationship between self-compassion and increased subjective sleep quality across diverse operationalizations and samples. Future research should focus on the moderating effects of intervention type, duration of intervention effects, and type of target population.

Abstract BACKGROUND Poor sleep quality is increasingly recognized as an important and potentially modifiable risk factor for cardiovascular disease (CVD). Impaired endothelial function may be 1 mechanism underlying the association between poor sleep and CVD risk. The present study examined the relationship between objective measures of sleep quality and endothelial function in a sample of untreated hypertensive adults. METHODS Participants were 127 men (N = 74) and women (N = 53), including 55 African Americans and 72 White Americans, aged 40–60 years (mean age, 45.3 ± 8.5 years), with untreated hypertension (systolic blood pressure 130–159 mm Hg and/or diastolic blood pressure 85–99 mm Hg). Noninvasive brachial artery flow-mediated dilation (FMD) was assessed by ultrasound. Sleep parameters, including sleep efficiency (SE), total sleep time (TST), and subjective sleep quality, were assessed over 7 consecutive days by wrist actigraphy. RESULTS Participants averaged 7.76 ± 1 hours in bed, with an average SE of 78 ± 9%, and TST of 6 ± 1 hours. Brachial FMD averaged 3.5 ± 3.1%. In multivariate analyses controlling for sex, race, body mass index, clinic blood pressure, income, smoking, alcohol use, and baseline arterial diameter, SE was positively associated with FMD (β = 0.28, P = 0.012). Subjective sleep quality (β = −0.04, P = 0.63) and TST (β = −0.11, P = 0.25) were unrelated to FMD. CONCLUSIONS Poor sleep as indicated by low SE was associated with impaired FMD. These findings for SE are consistent with previous observations of other measures implicating poor sleep as a CVD risk factor. Interventions that improve sleep may also help lower CVD risk.

AbstractObjectivesSleep disturbance is often associated with migraine. However, there is a paucity of research investigating objective and subjective measures of sleep in migraineurs. 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 migraineurs, and healthy controls.MethodsA systematic search of five databases was conducted to find case-controlled studies which measured polysomnography and/or PSQI in migraineurs. Effect sizes (Hedges’ g) were entered into a random effects model meta-analysis.Results32 separate studies were eligible. Overall, adult migraineurs had higher PSQI scores than healthy controls (g = 0.75, p < .001). This effect was larger in chronic than episodic migraineurs (g = 1.03, p < .001, g = 0.63, p < .001 respectively). For polysomnographic studies, adult and pediatric migraineurs displayed a lower percentage of REM sleep (g = −0.22, p = 0.017, g = −0.71, p = 0.025 respectively) than healthy controls. Pediatric migraineurs also displayed less total sleep time (g = −1.37, p = 0.039), more wake (g = 0.52, p < .001) and shorter sleep onset latency (g = −0.37, p < .001) than healthy controls.ConclusionMigraineurs have significantly poorer subjective sleep quality, and altered sleep compared to healthy individuals – a finding which is particularly evident in children. This has implications for developing appropriate treatments. Further longitudinal empirical studies are required to enhance our understanding of this relationship.

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 architecture measured using polysomnography between adult and pediatric patients, and healthy controls.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’ g) 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.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 (g=0.75, p < .001, 95% confidence interval [95%CI]: 0.54 - 0.96). This effect was larger in those with chronic rather than episodic condition (g=1.03, p < .001, 95%CI: 0.37 - 1.01, g = 0.63, p < .001, 95%CI: 0.38 - 0.88 respectively). For polysomnographic studies, adults and children with migraine displayed a lower percentage of REM sleep (g=-0.22, p = 0.017, 95%CI: -0.41 - -0.04, g = -0.71, p = 0.025, 95%CI: -1.34 - -0.10 respectively) than controls. Pediatric patients displayed less total sleep time (g=-1.37, p = 0.039, 95%CI: -2.66 - -0.10), more wake (g=0.52, p < .001, 95%CI: 0.08 – 0.79) and shorter sleep onset latency (g=-0.37, p < .001, 95%CI: -0.54 - -0.21) than controls.Discussion:People with migraine have significantly poorer subjective sleep quality and altered sleep architecture compared to healthy individuals. Further longitudinal empirical studies are required to enhance our understanding of this relationship.
