Impact of peer review audit on occupational health report quality

Background: In a previous report, we described the implementation of a formal process for peer review of occupational health (OH) reports and a method of assessment of the outcomes of this process. The initial audit identified that 27% of OH reports required modifications. Aims: To assess formally, following implementation of this process, if changes in practice had occurred, i.e. whether fewer deficiencies were being identified in reports. Methods: We repeated a prospective internal audit of all peer reviewed OH reports between September and November 2011. We used an abbreviated assessment form, based on questions 4–8 and 10–12 of the modified SAIL (Sheffield Assessment Instrument for Letters), with four possible outcomes: no action, no changes made to report following discussion with author, changes made without discussion with author and changes made following discussion with author. Results: One hundred seventy-three reports by 10 clinicians were audited. The audit identified a 13% reduction in OH reports requiring modifications (from 27 to 14%) compared with the previous cycle. Where modifications were required, 8% of these were related to minor typographical, spelling and grammar errors and 6% were for more complex reasons. Implementation of this process also produced a reduction in clinical complaints about OH reports from customers, from three in the preceding year to none 2 years later. Conclusions: Peer review improved the standard of OH reports and was associated with a reduction in customer complaints about reports

Emergency personnel neuroticism, health and lifestyle : a UK biobank study

Background: Emergency personnel face unpredictable and challenging incidents and their resilience and ability to cope influences their well-being. Personality traits, such as neuroticism, are postulated to be robust predictors of health and health behaviours. Despite evidence in the general population that neuroticism can positively impact health and health behaviours; to date neuroticism in emergency personnel has primarily been associated with adverse health outcomes. Aims: To assess whether neuroticism has a negative or positive impact on subjective and objective health and health behaviours in emergency personnel. Methods: This study used cross-sectional UK Biobank baseline data of emergency personnel (police, firemen and paramedics). Logistic regression models examined the strength of the associations of neuroticism tertiles with subjective (self-reported overall health and chronic conditions) and objective health (abdominal obesity) and self-reported smoking, sleeping, alcohol use and exercise levels. Results: High neuroticism was positively associated with poorer subjective health outcomes in all emergency personnel (n = 2483). The association between neuroticism and chronic disease/s was significant for police in the second (odds ratio [OR] = 1.93, 95% confidence interval [CI] = 1.15-1.94) and third (OR = 1.62, 95% CI = 1.21-2.16) neuroticism tertiles. Neuroticism in firemen was associated with reduced abdominal obesity (OR = 0.49, 95% CI = 0.25-0.96) and increased exercise (OR = 2.14, 95% CI = 1.07-4.25). Conclusions: We observed positive and negative associations between neuroticism and health outcomes and behaviours. While differences were observed across the emergency personnel groups, more research is needed to better understand how personality traits may impact health in workers with physically and mentally intense jobs

An interface capturing method for liquid-gas flows at low-Mach number

Multiphase, compressible and viscous flows are of crucial importance in a wide range of scientific and engineering problems. Despite the large effort paid in the last decades to develop accurate and efficient numerical techniques to address this kind of problems, current models need to be further improved to address realistic applications. In this context, we propose a numerical approach to the simulation of multiphase, viscous flows where a compressible and an incompressible phase interact in the low-Mach number regime. In this frame, acoustics is neglected but large density variations of the compressible phase can be accounted for as well as heat transfer, convection and diffusion processes. The problem is addressed in a fully Eulerian framework exploiting a low-Mach number asymptotic expansion of the Navier-Stokes equations. A Volume of Fluid approach (VOF) is used to capture the liquid-gas interface, built on top of a massive parallel solver, second order accurate both in time and space. The second-order-pressure term is treated implicitly and the resulting pressure equation is solved with the eigenexpansion method employing a robust and novel formulation. We provide a detailed and complete description of the theoretical approach together with information about the numerical technique and implementation details. Results of benchmarking tests are provided for five different test cases

The impact of Covid-19 on research into work and health

Background: The global coronavirus (Covid-19) pandemic created a profound disruption to the delivery of planned scientific research with unknown immediate and potentially longer-term impacts. Aims: We explored researchers’ experiences of the impact of the pandemic on the continued development and delivery of research into work and health, and on research infrastructure in this field. Methods: A cross-sectional study. Results: Thirty-three questionnaires were completed, representing a response rate of 15%. Sixty-one per cent of respondents were female, the majority (78%) had over 11 years of research experience and 76% worked mainly in academia. Most respondents (88%) were able to progress with research during the pandemic. A small proportion (4%) had studies paused or suspended due to the pandemic, while a larger proportion (19%) had research staff redeployed to assist with other studies or furloughed. Respondents described a range of emerging practical and logistical issues for research into work and health during the pandemic. Some benefited from increased opportunities to collaborate on new multidisciplinary studies, opportunities to engage participants in work and health research, and more flexible and inclusive work practices. Others experienced challenges that had an adverse impact, such as hampering research delivery (e.g. barriers to participant screening and intervention delivery), poor (home) working environments, reduced team cohesion and isolation. A range of future priorities for research was highlighted. Conclusions: We describe lessons learned and opportunities that can be used to support or further research activities in the field of work and health research in the future

A novel approach to early sickness absence management: The EASY (Early Access to Support for You) way

BACKGROUND: Sickness absence (SA) is multi-causal and remains a significant problem for employees, employers and society. This makes it necessary to concurrently manage a particular disabling condition and consider the working environment and employee-employer relationship. OBJECTIVE: To describe and examine the components of a novel SA management service Early Access to Support for You (EASY) and discuss their potential influence on the intervention. METHODS: A new sickness absence model, starting from day one of absence, was created called EASY. EASY is planned to support both employees and managers and comprises elements already found to be associated with reduction of SA, such as maintaining regular contact; early biopsychosocial case-management; physiotherapy; mental-health counselling; work modification; phased return-to-work; and health promotion activities. RESULTS: During the EASY implementation period, the SA rate at a health board reversed its trend of being one of the highest rates in the Scottish National Health Service (NHS) and EASY was considered helpful by both managers and employees. CONCLUSIONS: This paper describes an innovative occupational health intervention to sickness absence management based on the bio-psychosocial model to provide early intervention, and discusses the pros and cons of applying cognitive behavioural principles at an early stage in sickness-absence events, in order to improve return-to-work outcomes

Prospective Environmental Life Cycle Assessment of Nanosilver T-Shirts

A cradle-to-grave life cycle assessment (LCA) is performed to compare nanosilver T-shirts with conventional T-shirts with and without biocidal treatment. For nanosilver production and textile incorporation, we investigate two processes: flame spray pyrolysis (FSP) and plasma polymerization with silver co-sputtering (PlaSpu). Prospective environmental impacts due to increased nanosilver T-shirt commercialization are estimated with six scenarios. Results show significant differences in environmental burdens between nanoparticle production technologies: The "cradle-to-gate" climate footprint of the production of a nanosilver T-shirt is 2.70 kg of CO2-equiv (FSP) and 7.67-166 kg of CO2-equiv (PlaSpu, varying maturity stages). Production of conventional T-shirts with and without the biocide triclosan has emissions of 2.55 kg of CO2-equiv (contribution from triclosan insignificant). Consumer behavior considerably affects the environmental impacts during the use phase. Lower washing frequencies can compensate for the increased climate footprint of FSP nanosilver T-shirt production. The toxic releases from washing and disposal in the life cycle of T-shirts appear to be of minor relevance. By contrast, the production phase may be rather significant due to toxic silver emissions at the mining site if high silver quantities are require

A New Method to Address Unmet Needs for Extracting Individual Cell Migration Features from a Large Number of Cells Embedded in 3D Volumes

Background: In vitro cell observation has been widely used by biologists and pharmacologists for screening molecule-induced effects on cancer cells. Computer-assisted time-lapse microscopy enables automated live cell imaging in vitro, enabling cell behavior characterization through image analysis, in particular regarding cell migration. In this context, 3D cell assays in transparent matrix gels have been developed to provide more realistic in vitro 3D environments for monitoring cell migration (fundamentally different from cell motility behavior observed in 2D), which is related to the spread of cancer and metastases. Methodology/Principal Findings: In this paper we propose an improved automated tracking method that is designed to robustly and individually follow a large number of unlabeled cells observed under phase-contrast microscopy in 3D gels. The method automatically detects and tracks individual cells across a sequence of acquired volumes, using a template matching filtering method that in turn allows for robust detection and mean-shift tracking. The robustness of the method results from detecting and managing the cases where two cell (mean-shift) trackers converge to the same point. The resulting trajectories quantify cell migration through statistical analysis of 3D trajectory descriptors. We manually validated the method and observed efficient cell detection and a low tracking error rate (6%). We also applied the method in a real biological experiment where the pro-migratory effects of hyaluronic acid (HA) were analyzed on brain cancer cells. Using collagen gels with increased HA proportions, we were able to evidence a dose-response effect on cell migration abilities. Conclusions/Significance: The developed method enables biomedical researchers to automatically and robustly quantify the pro- or anti-migratory effects of different experimental conditions on unlabeled cell cultures in a 3D environment. © 2011 Adanja et al.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
