Comparing Views about Evidence in Ontario Public Health Units: A Qualitative Descriptive Study
Background: Ways of perceiving evidence by public health managers, practitioners and policy makers is one of the key determinants of evidence uptake. Recent public policy in Ontario requires programs to be based on evidence. Therefore, understanding views about evidence in both practice and policy contexts is important to bridge the research-policy-practice gap in public health.
Objective and Methods: This qualitative descriptive study examined understandings about evidence in Ontario public health units by comparing perspectives from managers and frontline staff across six geographically-diverse units. A secondary qualitative content analysis was used to re-analyze transcripts of focus groups from the Renewal of Public Health Systems (RePHS) research project.
Results: Similarities and differences were revealed with respect to how public health managers and frontline staff view evidence. Although both managers and frontline staff understand that multiple forms of evidence exist and that these forms must be integrated when making decisions regarding program development and implementation, frontline staff highlighted the role of practice-based evidence. Both groups named tools and processes that were available to assist their decision-making. Frontline staff indicated capacity building as important for supporting evidence use. Both groups noted that leadership could present a challenge to evidence-based programs if not supportive of the evidence-based solution for public health problems. However, the understanding of leadership differed between frontline staff and managers.
Conclusion: Findings from this study provide insight into how use of evidence can be promoted and how to better support policy implementation efforts within practice contexts

Marine inspired textured materials for reduction of biofouling on surfaces
Biofouling on deployed in-situ sensors without regular removal or cleaning can disrupt sensor data collected. The current replacement antifouling (AF) materials under development are largely unsuited to sensor technologies as they have been developed with large scale applications in mind, such as those required by the shipping industry. Therefore, a strategy for the development of novel, sustainable, antifouling materials for sensor applications is required. Bio-inspiration refers to adapting strategies already developed in the natural world to problems encountered in modern science and technology. Engineered surfaces capable of controlling cellular behaviour under natural conditions are challenging to design due to the diversity of attaching cell types in environments such as marine waters, where many variations in cell shape, size and adhesion strategy exist. Nevertheless, understanding interactions between a cell and a potential substrate for adhesion, including topographically driven settlement cues, offers a route to designing surfaces capable of controlling cell settlement. Biomimetic design of artificial surfaces, based upon microscale features from natural surfaces, can be utilized as model surfaces to understand cell-surface interactions. In this study it was hypothesized that an AF effect could be induced through the replication of a synthetic surface. Scophthalmus rhombus (Brill) is a small flatfish occurring in marine waters of the Mediterranean as well as in Norway and Iceland. It inhabits sandy and muddy coastal waters from 5 to 80 metres. Its skin changes colour depending on the environment but is generally brownish with light and dark freckles and a creamy underside. S. rhombus is oval in shape and its flesh is white[1], [2]. In this study, the micro topography of the brill scale is characterized for the first time which may serve as a trend for the design of a marine inspired biomimetic surface texture. Natural dermal scales of S. rhombus are artificially replicated using 3-D printing and mould casting technologies. The replication methods are then tested for initial colonization of fouling species using 3 h immersion testing using diatom species, CCAP 1052/1B, Phaeodactylum tricornutum. The aim of this study was to discover the potential of using textured surfaces inspired by nature in particular marine organisms to combat fouling. This work identifies simple textures that can reduce fouling in its early stages which can contribute to antifouling coatings on sensors for monitoring in the marine environment
Rural Men’s Health, Health Information Seeking, and Gender Identities: A Conceptual Theoretical Review of the Literature
Beginning as early as 2009, recent shifts in Canadian health care delivery indicate that access to health information is essential to promote and maintain a healthy population. It is important to understand how and where various populations, such as underresourced rural populations, access health information so that public health agencies can develop and deliver appropriate information with, for, and in these contexts. There is a paucity of research that specifically examines how rural Canadian men seek health information; therefore, this review aimed to conceptualize this process based on three dynamic key constructs: health patterns of rural Canadians, health information–seeking behaviors, and rural gender identities. This conceptual theoretical literature review included 91 articles at the intersection of these three constructs. Discussion focuses on how residing in a rural region influences men’s health and health care access. Health information–seeking behaviors are discussed in terms of social networks and framed with a rural context. Connell’s theory of masculinity provides a useful approach to dissecting how rural men’s gender identities influence their health attitudes, and how such attitudes are embedded in rural social and cultural norms. Each major construct—health in rural Canada, health information seeking, and rural gender identities—is discussed to highlight how specific embodiments of masculinity may promote and inhibit men’s health information–seeking and positive health behaviors

Unraveling spatiotemporal variability of arbuscular mycorrhizal fungi in a temperate grassland plot. Environmental Microbiology, 22(3),(2020): 873-888, doi:10.1111/1462-2920.14653.Soils provide a heterogeneous environment varying in space and time; consequently, the biodiversity of soil microorganisms also differs spatially and temporally. For soil microbes tightly associated with plant roots, such as arbuscular mycorrhizal fungi (AMF), the diversity of plant partners and seasonal variability in trophic exchanges between the symbionts introduce additional heterogeneity. To clarify the impact of such heterogeneity, we investigated spatiotemporal variation in AMF diversity on a plot scale (10 × 10 m) in a grassland managed at low intensity in southwest Germany. AMF diversity was determined using 18S rDNA pyrosequencing analysis of 360 soil samples taken at six time points within a year. We observed high AMF alpha‐ and beta‐diversity across the plot and at all investigated time points. Relationships were detected between spatiotemporal variation in AMF OTU richness and plant species richness, root biomass, minimal changes in soil texture and pH. The plot was characterized by high AMF turnover rates with a positive spatiotemporal relationship for AMF beta‐diversity. However, environmental variables explained only ≈20% of the variation in AMF communities. This indicates that the observed spatiotemporal richness and community variability of AMF was largely independent of the abiotic environment, but related to plant properties and the cooccurring microbiome.We thank the managers of the three Exploratories, Kirsten Reichel‐Jung, Swen Renner, Katrin Hartwich, Sonja Gockel, Kerstin Wiesner, and Martin Gorke for their work in maintaining the plot and project infrastructure; Christiane Fischer and Simone Pfeiffer for giving support through the central office, Michael Owonibi and Andreas Ostrowski for managing the central data base, and Eduard Linsenmair, Dominik Hessenmöller, Jens Nieschulze, Ernst‐Detlef Schulze, Wolfgang W.

Research priorities for shoulder surgery : results of the 2015 James Lind Alliance patient and clinician priority setting partnership
OBJECTIVE: To run a UK based James Lind Alliance Priority Setting Partnership for 'Surgery for Common Shoulder Problems'. SETTING: This was a nationally funded and conducted process. It was organised from a musculoskeletal research centre and Biomedical Research Unit in Oxford. PARTICIPANTS: UK shoulder patients, carers and clinicians, involved in treating patients with shoulder pain and shoulder problems that might require surgery. INTERVENTIONS: These were national electronic and paper surveys capturing treatment uncertainties that are important to shoulder patients, carers and clinicians. OUTCOME MEASURES: The outcomes relevant to this study were the survey results and rankings. RESULTS: The process took 18 months to complete, with 371 participants contributing 404 in scope questions. The James Lind process then produced a final 10 research priorities and uncertainties that relate to the scope of 'Surgery for Common Shoulder Problems'. CONCLUSIONS: The final top 10 UK research priorities have been produced and are now being disseminated to partner organisations and funders to guide funding of shoulder research for the next 5-10 years on topics that are important to patients, their carers and clinicians
Moving Towards a New Vision: Implementation of a Public Health Policy Intervention
Background
Public health systems in Canada have undergone significant policy renewal over the last decade in response to threats to the public’s health, such as severe acute respiratory syndrome. There is limited research on how public health policies have been implemented or what has influenced their implementation. This paper explores policy implementation in two exemplar public health programs -chronic disease prevention and sexually-transmitted infection prevention - in Ontario, Canada. It examines public health service providers’, managers’ and senior managements’ perspectives on the process of implementation of the Ontario Public Health Standards 2008 and factors influencing implementation.
Methods
Public health staff from six health units representing rural, remote, large and small urban settings were included. We conducted 21 focus groups and 18 interviews between 2010 (manager and staff focus groups) and 2011 (senior management interviews) involving 133 participants. Research assistants coded transcripts and researchers reviewed these; the research team discussed and resolved discrepancies. To facilitate a breadth of perspectives, several team members helped interpret the findings. An integrated knowledge translation approach was used, reflected by the inclusion of academics as well as decision-makers on the team and as co-authors.
Results
Front line service providers often were unaware of the new policies but managers and senior management incorporated them in operational and program planning. Some participants were involved in policy development or provided feedback prior to their launch. Implementation was influenced by many factors that aligned with Greenhalgh and colleagues’ empirically-based Diffusion of Innovations in Service Organizations Framework. Factors and related components that were most clearly linked to the OPHS policy implementation were: attributes of the innovation itself; adoption by individuals; diffusion and dissemination; the outer context – interorganizational networks and collaboration; the inner setting – implementation processes and routinization; and, linkage at the design and implementation stage.
Conclusions
Multiple factors influenced public health policy implementation. Results provide empirical support for components of Greenhalgh et al’s framework and suggest two additional components – the role of external organizational collaborations and partnerships as well as planning processes in influencing implementation. These are important to consider by government and public health organizations when promoting new or revised public health policies as they evolve over time. A successful policy implementation process in Ontario has helped to move public health towards the new vision
