The association of depression and all-cause and cause-specific mortality: an umbrella review of systematic reviews and meta-analyses
Background: Depression is a prevalent and disabling mental disorder that frequently co-occurs with a wide range of chronic conditions. Evidence has suggested that depression could be associated with excess all-cause mortality across different settings and populations, although the causality of these associations remains unclear. Methods: We conducted an umbrella review of systematic reviews and meta-analyses of observational studies. PubMed, PsycINFO, and Embase electronic databases were searched through January 20, 2018. Systematic reviews and meta-analyses that investigated associations of depression and all-cause and cause-specific mortality were selected for the review. The evidence was graded as convincing, highly suggestive, suggestive, or weak based on quantitative criteria that included an assessment of heterogeneity, 95% prediction intervals, small-study effects, and excess significance bias. Results: A total of 26 references providing 2 systematic reviews and data for 17 meta-analytic estimates met inclusion criteria (19 of them on all-cause mortality); data from 246 unique studies (N = 3,825,380) were synthesized. All 17 associations had P < 0.05 per random effects summary effects, but none of them met criteria for convincing evidence. Associations of depression and all-cause mortality in patients after acute myocardial infarction, in individuals with heart failure, in cancer patients as well as in samples from mixed settings met criteria for highly suggestive evidence. However, none of the associations remained supported by highly suggestive evidence in sensitivity analyses that considered studies employing structured diagnostic interviews. In addition, associations of depression and all-cause mortality in cancer and post-acute myocardial infarction samples were supported only by suggestive evidence when studies that tried to adjust for potential confounders were considered. Conclusions: Even though associations between depression and mortality have nominally significant results in all assessed settings and populations, the evidence becomes weaker when focusing on studies that used structured interviews and those that tried to adjust for potential confounders. A causal effect of depression on all-cause and cause-specific mortality remains unproven, and thus interventions targeting depression are not expected to result in lower mortality rates at least based on current evidence from observational studies

Challenges and Benefits of Standardising Early Warning Systems: A Case Study of New Zealandâs Volcanic Alert Level System
Volcano early warning systems are used globally to communicate volcano-related information to diverse stakeholders ranging from specific user groups to the general public, or both. Within the framework of a volcano early warning system, Volcano Alert Level (VAL) systems are commonly used as a simple communication tool to inform society about the status of activity at a specific volcano. Establishing a VAL system that is effective for multiple volcanoes can be challenging, given that each volcano has specific behavioural characteristics. New Zealand has a wide range of volcano types and geological settings, including rhyolitic calderas capable of very large eruptions (\u3e500 km 3 ) and frequent unrest episodes, explosive andesitic stratovolcanoes, and effusive basaltic eruptions at both caldera and volcanic field settings. There is also a range in eruption frequency, requiring the VAL system to be used for both frequently active âopen-ventâ volcanoes, and reawakening âclosed-ventâ volcanoes. Furthermore, New Zealandâs volcanoes are situated in a variety of risk settings ranging from the Auckland Volcanic Field, which lies beneath a city of 1.4 million people; to Mt. Ruapehu, the location of popular ski fields that are occasionally impacted by ballistics and lahars, and produces tephra that falls in distant cities. These wide-ranging characteristics and their impact on society provide opportunities to learn from New Zealandâs experience with VAL systems, and the adoption of a standardised single VAL system for all of New Zealandâs volcanoes following a review in 2014. This chapter outlines the results of qualitative research conducted in 2010â2014 with key stakeholders and scientists, including from the volcano observatory at GNS Science, to ensure that the resulting standardised VAL system is an effective communication tool. A number of difficulties were faced in revising the VAL system so that it remains effective for all of the volcanic settings that exist in New Zealand. If warning products are standardised too much, end-user decision making and action can be limited when unusual situations occur, e.g., there may be loss of specific relevance in the alert message. Specific decision-making should be based on more specific parameters than the VAL alone, however wider VAL system standardisation can increase credibility, a known requirement for effective warning, by ensuring that warning sources are clear, trusted and widely understood. With a credible source, user groups are less likely to look for alternatives or confirmation, leading to faster action. Here we consider volcanic warnings within the wider concept of end-to-end multi-hazard early warning systems including detection, evaluation, notification, decision-making and action elements (based on Carsell et al. 2004)
Midterm results after operatively stabilised shoulder dislocations in elderly patients
Anterior shoulder dislocation is frequently seen in young patients. The therapeutic regime in elderly patients after shoulder dislocation is less clearly defined. The aim of this study was to compare the clinical benefit of operative stabilisation following anterior shoulder dislocation in young versus elderly patients. Seventy-two patients with anterior shoulder dislocations were allocated into two groups. Group 1 (>â40Â years of age) consisted of 23 patients, and group 2 (<â40Â years of age) consisted of 49 patients. Operative stabilisation resulted in a significant reduction in recurrence rate in both groups. However, the clinical functional results measured by the Constant score, Rowe score and disabilities of the arm, shoulder and hand (DASH) score revealed significantly better outcomes in the younger (group 2) than in the older group (group 1). These results indicate that while operative stabilisation is equally effective in reducing recurrent shoulder dislocation in the elderly functional outcomes are not as good as in younger patients
Reshaping the Hybrid Role of Public Servants:Identifying the Opportunity Space for Co-production and the Enabling Skills Required by Professional Co-producers
This chapter starts by introducing how the public sector has adopted different governance metatrends during the last century and how the adoption of these metatrends over time has led to new, hybrid roles for service users and frontline staff. The focus in this chapter is dedicated to the changing roles of the frontline staff and especially the role ascribed to them as professional coproducers. The premise is that professional co-producers must build their capacity to navigate in the local co-production context that is a hybrid of the Old Public Administration, New Public Management, and New Public Governance. This complex, hybrid context is framed in the chapter as âthe opportunity space for coproduction.â The problem is that this opportunity space represents an arena in which there is potential for the creation of âdouble or triple pressureâ on the professional co-producers because they are expected to handle top-down and bottom-up expectations simultaneously - and perhaps also horizontal pressures stemming from the expectations of staff from other organizations (interorganizational collaborations). The argument is that professional co-producers must build their capacity to navigate in this dynamic context, acting together with service users and members from other organizations.</p
