Mental Resilience

Abstract Background: Mental resilience has emerged as a recent focus within the context of positive psychology. Resilience is a potentially modifiable construct. Some preliminary evidence from experimental studies as well as clinical populations has indicated that sleep may be related to mental resilience, but little is known about this relationship in healthy populations. Sleep is a complex with multi-factorial outcome, although the majority of research effort has focused on sleep duration and sleep quality. Our systematic review and meta-analysis will identify original research data from observational studies to assess if sleep duration and/or sleep quality is associated with levels of psychological resilience amongst healthy children, adolescents and adults. We hypothesize that there will be a positive association between sleep duration/quality and mental resilience across all age groups. Methods: A comprehensive, systematic search for literature will be conducted in June 2020 (LÖ), covering a total of eight academic databases (PubMed, Embase, PsycInfo, PsycArticles, CINAHL, Scopus, Web of Science and Academic Search Complete). Sources for grey materials will also be included and experts in the field will also be contacted for inclusion of unpublished data. PubMed and PubMed’s MeSH terms were used to develop the search strategy and systematically identify relevant search terms. Two authors (IG & AA) will screen the articles independently, and a third researcher (TA) will resolve discrepancies. The primary outcome is mental/psychological resilience. The systematic review will adhere to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.Discussion: The results of our systematic review and meta-analysis are intended to be published in an appropriate scientific peer-reviewed journal and will be made publicly available. The findings from our project are envisioned to inform and educate the public as well as healthcare and education systems, globally. Our systematic review protocol has been peer-reviewed and is currently registered in the international database, PROSPERO.Systematic review registration: CRD42020191119 (submitted on 2 July 2020).

Abstract Background : To assess the association of sleep duration and quality with the risk of preterm birth. Methods : Relevant studies were retrieved from the PubMed and Web of Science databases up to September 30, 2018. The reference lists of the retrieved articles were reviewed. Random effects models were applied to estimate summarized relative risks (RRs) and 95% confidence intervals (CIs). Results : Ten identified studies (nine cohort studies and one case-controlled study) examined the associations of sleep duration and quality with the risk of preterm birth. As compared with women with the longest sleep duration, the summary RR was 1.23 (95% CI = 1.01–1.50) for women with the shortest sleep duration, with moderate between-study heterogeneity ( I 2 = 57.4%). Additionally, as compared with women with good sleep quality, the summary RR was 1.54 (95% CI = 1.18–2.01) for women with poor sleep quality (Pittsburgh Sleep Quality Index > 5), with high between-study heterogeneity ( I 2 = 76.7%). Funnel plots as well as the Egger’s and Begg’s tests revealed no evidence of publication bias. Conclusions : This systematic review and meta-analysis revealed that short sleep duration and poor sleep quality may be associated with an increased risk of preterm birth. Further subgroup analyses are warranted to test the robustness of these findings as well as to identify potential sources of heterogeneity.

Context: Increasing evidence suggests that circadian and sleep parameters influence cognitive function with aging. Objective: To evaluate observational studies of sleep duration and cognition in older adults. Data Sources: A systematic review of OVID Medline and PsycINFO through September 2015, and review of bibliographies from studies identified. Study Selection: English-language articles reporting observational studies of sleep duration and cognitive function in older populations. Data Extraction: Data extraction by 2 authors using predefined categories of desired information. Results: Thirty-two studies met our inclusion criteria, with nearly two-thirds published in the past 4 years. One-third of studies indicated that extreme sleep durations were associated with worse cognition in older adults. More studies favored an association with long vs. short sleep durations (35 vs. 26% of studies, respectively). Four studies found that greater changes in sleep duration over time were related to lower cognition. Study design and analytic methods were very heterogeneous across studies; therefore, meta-analysis was not undertaken. Limitations: We reviewed English-language manuscripts only, with a qualitative summary of studies identified. Conclusions and Implications of Key Findings: Observational studies of sleep duration and cognitive function in older adults have produced mixed results, with more studies suggesting that long (rather than short) sleep durations are related to worse cognition. Studies more consistently indicate that greater changes in sleep duration are associated with poor cognition. Future studies should be prospectively designed, with objective sleep assessment and longer follow-up periods; intervention studies are also needed to identify strategies for promoting cognitive health with aging.

Sarcopenia is an age-related condition. However, the prevalence of sarcopenia may increase due to a range of other factors, such as sleep quality/duration. Therefore, the aim of the study is to conduct a systematic review with meta-analysis to determine the prevalence of sarcopenia in older adults based on their self-reported sleep duration. Methods: Three electronic databases were used—PubMed-Medline, Web of Science, and Cochrane Library. We included studies that measured the prevalence of sarcopenia, divided according to sleep quality and excluded studies (a) involving populations with neuromuscular pathologies, (b) not showing prevalence values (cases/control) on sarcopenia, and (c) not including classificatory models to determine sleep quality. Results: high prevalence values in older adults with both long and short sleep duration were shown. However, prevalence values were higher in those with inadequate sleep (<6–8 h or low efficiency) (OR 0.76; 95% CI (0.70–0.83); Q = 1.446; p = 0.695; test for overall effect, Z = 6.01, p < 0.00001). Likewise, higher prevalence levels were shown in men (OR 1.61; 95% CI (0.82–3.16); Q = 11.80; p = 0.0189) compared to women (OR 0.77; 95% CI (0.29–2.03); Q = 21.35; p = 0.0003). Therefore, the prevalence of sarcopenia appears to be associated with sleep quality, with higher prevalence values in older adults who have inadequate sleep.

ObjectivesTo assess the longitudinal evidence of the relationships between sleep disturbances (of quantity and quality) and dyslipidaemia in the general population and to quantify such relationships.SettingSystematic review and meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.MethodsWe performed a systematic search of PubMed and Embase (up to 9 September 2017), complemented with manual searches, of prospective population studies describing the association between sleep duration and quality and the incidence of dyslipidaemias. Relative risks (95% CIs) were extracted and pooled using a random effects model. Subgroup analyses by lipid type were performed. Heterogeneity and publication bias were also assessed. Quality was assessed with Downs and Black score.ParticipantsStudies were included if they were prospective, had measured sleep quantity and/or quality at baseline and either incident cases of dyslipidaemia or changes in blood lipid fractions assessed prospectively.Primary outcome measuresIncidence of dyslipidaemia and changes in lipid fractions. Dyslipidaemia was defined as a high total cholesterol, triglycerides, low-density lipoprotein cholesterol or low high-density lipoprotein cholesterol compared with the reference group.ResultsThirteen studies were identified (eight using sleep duration, four sleep quality and one both). There was heterogeneity in the sleep quality aspects and types of lipids assessed. Classification of sleep duration (per hour/groups) also varied widely. In the pooled analysis of sleep duration (6 studies, 16 cohort samples; 30 033 participants; follow-up 2.6–10 years), short sleep was associated with a risk of 1.01 (95% CI 0.93 to 1.10) of developing dyslipidaemia, with moderate heterogeneity (I2=56%, P=0.003) and publication bias (P=0.035). Long sleep was associated with a risk of 0.98 (95% CI 0.87 to 1.10) for dyslipidaemia, with heterogeneity (I2=63%, P<0.001) and no significant publication bias (P=0.248).ConclusionThe present analysis was unable to find supportive evidence of a significant relationship between sleep duration and the development of dyslipidaemia. However, heterogeneity and small number of studies limit the interpretation.PROSPERO registration numberCRD42016045242.

Background: Studies have shown that patients with psoriasis have higher risk of CVD, independent of traditional CVD risk factors. However, pathophysiology of the development of CVD in psoriasis is not well known. Arterial stiffness has been recognized as an independent predictor of cardiovascular risk. It is controversial whether psoriasis and arterial stiffness is associated. In this systematic review and meta-analysis, we sought to assess the hypothesis that patients with psoriasis have increased arterial stiffness compared with controls. Methods: Systematic literature search was performed using MEDLINE and EMBASE databases from inception to May 2016. We included original research publications that contained data on arterial stiffness and psoriasis. Aortic pulse wave velocity (aPWV) is the non-invasive marker for assessment of arterial stiffness. We compared aPWV between patients with psoriasis and controls and estimated the pooled mean difference (MD) and 95% confidence interval (CI) of aPWV using a random-effects model meta-analysis. Results: Data from five observational studies involving 438 participants (233 with psoriasis) were extracted and included in the meta-analysis. Pooled MD of aPWV was 1.17 m/sec higher in patients with psoriasis compared with controls (95% CI: 0.78-1.55, P-value<0.01, I 2 = 69%). There is no change in the direction or statistical significance of MD of aPWV after removing each study at a time in the sensitivity analysis. Conclusion: Psoriasis is associated with increased arterial stiffness. Assessment of arterial stiffness parameters may be important for early detection of cardiovascular deterioration in psoriasis patients.
