Introduction: For authors, selecting a target journal to submit a manuscript is a critical decision with career implications. In the discipline of medical education, research conducted in 2016 found that authors were influenced by multiple factors such as a journal's prestige and its mission. However, since this research was conducted the publishing landscape has shifted to include a broader variety of journals, an increased threat of predatory journals, and new publishing models.

Background: Biologic therapies have led to increasing numbers of patients with psoriasis who have clear or nearly clear skin. It is current practice to continue biologic therapy indefinitely in these patients, which contributes to a substantial long-term drug and healthcare burden. 'As needed' biologic therapy in psoriasis may address this; however, our understanding of patient and clinician perceptions of this strategy is limited.

Wildfires have increased in frequency in many ecosystems, with implications for human health and the environment, including water quality. Increased fire frequency and urbanization also raise the prospect of fires burning into urban areas, mobilizing pollutants few have considered to date. As a result, water quality managers lack information to anticipate, respond to and potentially mitigate wildfire impacts.

Background: Nonadherence to immune-modifying therapy is a complex behaviour which, before the COVID-19 pandemic, was shown to be associated with mental health disorders in people with immune-mediated diseases. The COVID-19 pandemic has led to a rise in the global prevalence of anxiety and depression, and limited data exist on the association between mental health and nonadherence to immune-modifying therapy during the pandemic.

Objectives: To assess the extent of and reasons underlying nonadherence to systemic immune-modifying therapy during the COVID-19 pandemic in individuals with psoriasis, and the association between mental health and nonadherence.

This qualitative study explores how and why journalists use preprints-unreviewed research papers-in their reporting. Through thematic analysis of interviews conducted with 19 health and science journalists in the second year of the COVID-19 pandemic, it applies a theoretical framework that conceptualizes COVID-19 preprint research as a form of post-normal science, characterized by high scientific uncertainty and societal relevance, urgent need for political decision-making, and value-related policy considerations. Findings suggest that journalists approach the decision to cover preprints as a careful calculation, in which the potential public benefits and the ease of access preprints provided were weighed against risks of spreading misinformation.

This content analysis considered the San Francisco Homeless Project (SFHP), a collaboration of media organizations working to generate a wave of coverage to alleviate homelessness. The effort stood out for its proposed solutions to a systemic and complex issue involving multiple ecological levels of a community, the number and variety of organizations involved, and the ongoing nature of the project. Yet, little is known about its impact and potential for replication.

Journalists' health and science reporting aid the public's direct access to research through the inclusion of hyperlinks leading to original studies in peer-reviewed journals. While this effort supports the US-government mandate that research be made widely available, little is known about what research journalists share with the public. This cross-sectional exploratory study characterises US-government-funded research on cancer that appeared most frequently in news coverage and how that coverage varied by cancer type, disease incidence and mortality rates.

In this article, we investigate the surge in use of COVID-19-related preprints by media outlets. Journalists are a main source of reliable public health information during crises and, until recently, journalists have been reluctant to cover preprints because of the associated scientific uncertainty. Yet, uploads of COVID-19 preprints and their uptake by online media have outstripped that of preprints about any other topic.

Background: Registry data suggest that people with immune-mediated inflammatory diseases (IMIDs) receiving targeted systemic therapies have fewer adverse coronavirus disease 2019 (COVID-19) outcomes compared with patients receiving no systemic treatments.

Objectives: We used international patient survey data to explore the hypothesis that greater risk-mitigating behaviour in those receiving targeted therapies may account, at least in part, for this observation.

Methods: Online surveys were completed by individuals with psoriasis (globally) or rheumatic and musculoskeletal diseases (RMDs) (UK only) between 4 May and 7 September 2020.

Background: The multimorbid burden and use of systemic immunosuppressants in people with psoriasis may confer greater risk of adverse outcomes of coronavirus disease 2019 (COVID-19), but the data are limited.

Objective: Our aim was to characterize the course of COVID-19 in patients with psoriasis and identify factors associated with hospitalization.

Methods: Clinicians reported patients with psoriasis with confirmed/suspected COVID-19 via an international registry, Psoriasis Patient Registry for Outcomes, Therapy and Epidemiology of COVID-19 Infection.

Objective: To investigate the nature of physicians' use of research evidence in experimental conditions of open access to inform training and policy.

Design: This qualitative study was a component of a larger mixed-methods initiative that provided 336 physicians with relatively complete access to research literature via PubMed and UpToDate, for 1 year via an online portal, with their usage recorded in web logs. Using a semistructured interview protocol, a subset of 38 physician participants were interviewed about their use of research articles in general and were probed about their reasons for accessing specific articles as identified through their web logs.

Introduction: Through funding agency and publisher policies, an increasing proportion of the health sciences literature is being made open access. Such an increase in access raises questions about the awareness and potential utilization of this literature by those working in health fields.

Methods: A sample of physicians (N=336) and public health non-governmental organization (NGO) staff (N=92) were provided with relatively complete access to the research literature indexed in PubMed, as well as access to the point-of-care service UpToDate, for up to one year, with their usage monitored through the tracking of web-log data.

Physicians have many information needs that arise at the point of care yet go unmet for a variety of reasons, including uncertainty about which information resources to select. In this study, we aimed to identify the various types of physician information needs and how these needs relate to physicians' use of the database PubMed and the evidence summary tool UpToDate. We conducted semi-structured interviews with physicians (Stanford University, United States; n = 13; and University Medical Center Utrecht, the Netherlands; n = 9), eliciting participants' descriptions of their information needs and related use of PubMed and/or UpToDate.

Purpose: The research sought to ascertain the types and quantity of research evidence accessed by health personnel through PubMed and UpToDate in a university medical center over the course of a year in order to better estimate the impact that increasing levels of open access to biomedical research can be expected to have on clinical practice in the years ahead.

Methods: Web log data were gathered from the 5,042 health personnel working in the Stanford University Hospitals (SUH) during 2011. Data were analyzed for access to the primary literature (abstracts and full-text) through PubMed and UpToDate and to the secondary literature, represented by UpToDate (research summaries), to establish the frequency and nature of literature consulted.

Quality of the agricultural matrix profoundly affects biodiversity and dispersal in agricultural areas. Vegetatively complex coffee agroecosystems maintain species richness at larger distances from the forest. Epiphytes colonize canopy trees and provide resources for birds and insects and thus effects of agricultural production on epiphytes may affect other species.

Variations in intraocular pressure (IOP), observed by us and other authors in closed-system anterior chamber procedures, are explained using a simple hydrodynamic analysis based on the Bernoulli equation. Calculations show that the sudden increases in IOP (pressure spikes) measured during anterior segment surgery are due primarily to the small size of the infusion cannulas and are exacerbated by high infusion rates. Accurate measurement of these IOP variations requires placement of the pressure sensors in situ and is not possible by remote pressure sensing at the infusion line or the console.

The effectiveness of antimetabolic and anticollagen agents against proliferative vitreoretinopathy (PVR) was assessed by vitreous microtensiometry, a new technique that measures in situ the tensile strength of vitreous membranes. Two PVR models were produced in rabbits by intravitreal injection of bovine retinal pigment epithelial (RPE) or fibroblast cells, and the animals subsequently were treated with 5-fluorouracil (5-FU) and beta-aminopropionitrile (BAPN), administered alone or in combination. The fibroblast PVR model produced high-strength membranes that did not respond significantly to these therapies.
