Introduction

BACKGROUND: National quality registries (NQRs) purportedly facilitate quality improvement, while neither the extent nor the mechanisms of such a relationship are fully known. The aim of this case study is to describe the experiences of local stakeholders to determine those elements that facilitate and hinder clinical quality improvement in relation to participation in a well-known and established NQR on stroke in Sweden. METHODS: A strategic sample was drawn of 8 hospitals in 4 county councils, representing a variety of settings and outcomes according to the NQR's criteria. Semi-structured telephone interviews were conducted with 25 managers, physicians in charge of the Riks-Stroke, and registered nurses registering local data at the hospitals. Interviews, including aspects of barriers and facilitators within the NQR and the local context, were analysed with content analysis. RESULTS: An NQR can provide vital aspects for facilitating evidence-based practice, for example, local data drawn from national guidelines which can be used for comparisons over time within the organisation or with other hospitals. Major effort is required to ensure that data entries are accurate and valid, and thus the trustworthiness of local data output competes with resources needed for everyday clinical stroke care and quality improvement initiatives. Local stakeholders with knowledge of and interest in both the medical area (in this case stroke) and quality improvement can apply the NQR data to effectively initiate, carry out, and evaluate quality improvement, if supported by managers and co-workers, a common stroke care process and an operational management system that embraces and engages with the NQR data. CONCLUSION: While quality registries are assumed to support adherence to evidence-based guidelines around the world, this study proposes that a NQR can facilitate improvement of care but neither the registry itself nor the reporting of data initiates quality improvement. Rather, the local and general evidence provided by the NQR must be considered relevant and must be applied in the local context. Further, the quality improvement process needs to be facilitated by stakeholders collaborating within and outside the context, who know how to initiate, perform, and evaluate quality improvement, and who have the resources to do so

Sugar and low/no-calorie-sweetened beverage consumption and associations with body weight and waist circumference changes in five European cohort studies: the SWEET project.

PurposeResults of prospective studies investigating associations between low/no-calorie sweeteners (LNCS) and body weight-related outcomes are inconclusive. We conducted dose-response and theoretical replacement individual patient data meta-analyses using harmonised prospective data to evaluate associations between sugar-sweetened beverage (SSB) consumption, low/no-calorie sweetened beverage (LNCB) consumption, and changes in body weight and waist circumference.MethodsIndividual participant data were obtained from five European studies, i.e., Lifelines Cohort Study, NQplus study, Alpha Omega Cohort, Predimed-Plus study, and Feel4diabetes study, including 82,719 adults aged 18-89 with follow-up between 1 and 9 years. Consumption of SSB and LNCB was assessed using food-frequency questionnaires. Multiple regression analyses adjusting for major confounders and including substitution models were conducted to quantify associations in individual cohorts; random-effects meta-analyses were performed to pool individual estimates.ResultsOverall, pooled results showed weak adverse associations between SSB consumption and changes in body weight (+ 0.02 kg/y, 95%CI 0.00; 0.04) and waist circumference (+ 0.03 cm/y, 95%CI 0.01; 0.05). LNCB consumption was associated with higher weight gain (+ 0.06 kg/y, 95%CI 0.04; 0.08) but not with waist circumference. No clear associations were observed for any theoretical replacements, i.e., LNCB or water for SSB or water for LNCB.ConclusionIn conclusion, this analysis of five European studies found a weak positive association between SSB consumption and weight and waist change, whilst LNCB consumption was associated with weight change only. Theoretical substitutions did not show any clear association. Thus, the benefit of LNCBs as an alternative to SSBs remains unclear

Lifestyle and self-rated health: a cross-sectional study of 3,601 citizens of Athens, Greece

<p>Abstract</p> <p>Background</p> <p>Self-rated health (SRH) is a popular health measure determined by multiple factors. International literature is increasingly focusing on health-related behaviors such as smoking, dietary habits, physical activity, even religiosity. However, population-based studies taking into account multiple putative determinants of SRH in Greece are scarce. The aim of this study was to clarify possible determinants of SRH with an emphasis on the relationship between SRH and lifestyle variables in a large sample of urban citizens.</p> <p>Methods</p> <p>In this one-year cross-sectional study, a stratified random sample of 3,601 urban citizens was selected. Data were collected using an interview-based questionnaire about various demographic, socioeconomic, disease- and lifestyle related factors such as smoking, physical activity, dietary habits, sleep quality and religiosity. Multivariate logistic regression was used separately in three age groups [15-29 (N = 1,360), 30-49 (N = 1,122) and 50+ (N = 1,119) years old] in order to identify putative lifestyle and other determinants of SRH.</p> <p>Results</p> <p>Reporting of good SRH decreased with age (97.1%, 91.4% and 74.8%, respectively). Overall, possible confounders of the lifestyle-SRH relationship among age groups were sex, education, hospitalization during the last year, daily physical symptoms and disease status. Poor SRH was associated with less physical activity in the 15-29 years old (OR 2.22, 95%CI 1.14-4.33), with past or heavy smoking, along with no sleep satisfaction in the 30-49 years old (OR 3.23, 95%CI 1.35-7.74, OR 2.56, 95%CI 1.29-5.05, OR 1.79, 95%CI 1.1-2.92, respectively) and with obesity and no sleep satisfaction in the 50+ years old individuals (OR 1.83, 95%CI 1.19-2.81, OR 2.54, 95%CI 1.83-3.54). Sleep dissatisfaction of the 50+ years old was the only variable associated with poor SRH at the 0.001 p level of significance (OR 2.45, 99%CI 1.59 to 3.76). Subgroup analyses of the 15-19 years old individuals also revealed sleep dissatisfaction as the only significant variable correlated with SRH.</p> <p>Conclusions</p> <p>Slight differences in lifestyle determinants of SRH were identified among age groups. Sleep quality emerged as an important determinant of SRH in the majority of participants.</p

The Wnt Receptor Ryk Reduces Neuronal and Cell Survival Capacity by Repressing FOXO Activity During the Early Phases of Mutant Huntingtin Pathogenicity

The Wnt receptor Ryk is an evolutionary-conserved protein important during neuronal differentiation through several mechanisms, including γ-secretase cleavage and nuclear translocation of its intracellular domain (Ryk-ICD). Although the Wnt pathway may be neuroprotective, the role of Ryk in neurodegenerative disease remains unknown. We found that Ryk is up-regulated in neurons expressing mutant huntingtin (HTT) in several models of Huntington's disease (HD). Further investigation in Caenorhabditis elegans and mouse striatal cell models of HD provided a model in which the early-stage increase of Ryk promotes neuronal dysfunction by repressing the neuroprotective activity of the longevity-promoting factor FOXO through a noncanonical mechanism that implicates the Ryk-ICD fragment and its binding to the FOXO co-factor β-catenin. The Ryk-ICD fragment suppressed neuroprotection by lin-18/Ryk loss-of-function in expanded-polyQ nematodes, repressed FOXO transcriptional activity, and abolished β-catenin protection of mutant htt striatal cells against cell death vulnerability. Additionally, Ryk-ICD was increased in the nucleus of mutant htt cells, and reducing γ-secretase PS1 levels compensated for the cytotoxicity of full-length Ryk in these cells. These findings reveal that the Ryk-ICD pathway may impair FOXO protective activity in mutant polyglutamine neurons, suggesting that neurons are unable to efficiently maintain function and resist disease from the earliest phases of the pathogenic process in HD. © 2014 Tourette et al

When is a bed not a bed? Exploring the interplay of the material and virtual in negotiating home-work boundaries

© 2017, © 2017 Informa UK Limited, trading as Taylor & Francis Group. Working from home is often associated with possibilities of anytime-anyplace working and with a fusion of work and home. In this empirical paper, we explore how the sociomaterial contexts of home-working define and tether what is possible for home-workers in their negotiations with others. Drawing on qualitative data sets, Wengerian concepts are used by exploring the role of boundary objects and brokering in negotiating temporal and spatial boundaries around and across work and home. The home-workers’ bodies are shown to be the key boundary objects, through which technology objects and furniture objects are sometimes fused. Yet, such fusion is shown to be only temporary, always precariously situated and also mediated by identity-regulating norms and values of home-workers. The contribution of the paper is to highlight the limits of what is technologically possible by emphasising the role of the body and material objects in the home-working context

Self-rated Health with special reference to Prevalence, Determinants and Consequences

Objectives: The overall aim was to investigate determinants and consequences of global non-comparative self-ratings of health (SRH). Concerning determinants, the aim was more specifically to investigate the association between age, year of investigation, stress-theory based psychobiological variables, and SRH. Materials and methods: Papers I and IV were based on eight ongoing population-based cohort studies, with sampling performed 1973-2003. The study-population consisted of 11,880 men and women, aged 25-99 years, providing 14,470 observations. Papers II and III were based on a longitudinal study of 212 adult, healthy, women and men. Results: In women, SRH declined linearly with age and year of investigation, after adjustment for influence of covariates, while in men the association was based on a third degree polynomial function. The most important covariates were complaint score, sick-leave or disability pension, and leisure time physical activity. The final model explained 76.2% of the variance in women and 74.5% in men. SRH was directly associated with psychological resources and inversely associated with psychological strain, in healthy, adult, women and men. In men with SRH which decreased to fair or poor, higher levels of prolactin and lower levels of testosterone were observed at follow-up as compared to baseline. There were no associations between endocrine variables and SRH in women. There was a significant inverse association between SRH and mortality, disability pension, and sick-leave during follow-up, in women and men, adjusted for covariates. Associations between SRH and mortality were robust during the follow-up period. Conclusions: Age and year of investigation were associated with SRH, but differently in women and men. Psychological resources and psychological strain were consistently associated with SRH, but there were no robust associations between endocrine measures and SRH. SRH was associated with mortality, disability pension, and sick-leave, during follow-up. The association between SRH and mortality was robust during the follow-up perio

Perceived Stress, Psychological Resources and Salivary Cortisol

The aim of this chapter was to analyze associations between measures of cortisol in saliva withmeasures of perceived stress, using the Perceived Stress Scale (PSS), and of psychological resources interms of mastery, locus of control, self-esteem and sense of coherence. Only studies on healthy individualswere included and cortisol measures were grouped into single time point measures, deviation measures,Area Under the Curve (AUC), laboratory test responses, and dexamethasone suppression. For bothPerceived Stress Scale (PSS) and for psychological resources, most results of associations with salivacortisol were nonsignificant particularly for single measures and for cortisol awakening response. For PSSthe largest proportion of significant findings (38%) was seen for morning AUC, however with conflictingresults. For psychological resource constructs, mastery and sense of coherence were related to lower cortisollevel at baseline in standardized rest and high mastery was related to steeper diurnal slope in two studies.For self-esteem, no associations showed significant results. Differences in findings may to a large extent bedependent on theoretical assumptions made and methods use

Mental Health and Salivary Cortisol

Abstract: The aim of this chapter was to analyze associations between measures of cortisol in salivaand mental health and to see if divergent results were functions of the methods used. Measures ofmental health outcome included Major Depressive Disorder (MDD), symptoms of depression, andsymptoms of anxiety, Burnout (BO), and Vital Exhaustion (VE). Only studies on otherwise healthyindividuals were included. Cortisol measures were grouped into single time point measures, measuresof deviations, laboratory test responses, Area Under the Curve (AUC), and response to dexamethasone.Some consistency is seen for MDD, mainly higher mean levels. The results regarding single measuresand depressive mood are less consistent, but the overall picture for depression shows poorer diurnaldeviation and response to stress. Inconsistency among papers studying depression seems to be relatedmainly to the study population. Very few significant findings were found for anxiety, therefore cortisoldoes not seem to be strongly related to anxiety. Most of the statistical analysis does not show asignificant relationship between BO and cortisol, and when these are present, the results areinconsistent. One explanation seems to be the measures of BO used, probably due to the differentconceptual basis for BO. VE measured using the Maastricht Questionnaire seems to be related to apoorer cortisol response to stress and poorer diurnal deviation. The coexistence of BO and VE in manystudies does make it difficult to conclude how the different concepts are related to cortisol. However, aninteresting difference appeared between MDD and VE in response to dexamethasone administration,showing lower suppression in MDD patients and higher suppression in VE patients. A generalconclusion for all mental health measures is that a large proportion of non-significant findings are dueto low power and few sampling days combined with low contrasts between study groups and withinstudy populations. Generally, deviation measures such as diurnal deviation seem to be more validmeasures compared with single measures to capture possible changes in the hypothalamus-pituitaryadrenal axis, measured using salivary cortisol
