Randomised double-blind phase 3 clinical study testing impact of atorvastatin on prostate cancer progression after initiation of androgen deprivation therapy : study protocol
Introduction Blood cholesterol is likely a risk factor for prostate cancer prognosis and use of statins is associated with lowered risk of prostate cancer recurrence and progression. Furthermore, use of statins has been associated with prolonged time before development of castration resistance (CR) during androgen deprivation therapy (ADT) for prostate cancer. However, the efficacy of statins on delaying castration-resistance has not been tested in a randomised placebo-controlled setting. This study aims to test statins' efficacy compared to placebo in delaying development of CR during ADT treatment for primary metastatic or recurrent prostate cancer. Secondary aim is to explore effect of statin intervention on prostate cancer mortality and lipid metabolism during ADT. Methods and analysis In this randomised placebo-controlled trial, a total of 400 men with de novo metastatic prostate cancer or recurrent disease after primary treatment and starting ADT will be recruited and randomised 1:1 to use daily 80 mg of atorvastatin or placebo. All researchers, study nurses and patients will be blinded throughout the trial. Patients are followed until disease recurrence or death. Primary outcome is time to formation of CR after initiation of ADT. Serum lipid levels (total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL) and trigyserides) are analysed to test whether changes in serum cholesterol parameters during ADT predict length of treatment response. Furthermore, the trial will compare quality of life, cardiovascular morbidity, changes in blood glucose and circulating cell-free DNA, and urine lipidome during trial. Ethics and dissemination This study is approved by the Regional ethics committees of the Pirkanrnaa Hospital District, Science centre, Tampere, Finland (R18065M) and Tarto University Hospital, Tarto, Estonia (319/T-6). All participants read and sign informed consent form before study entry. After publication of results for the primary endpoints, anonymised summary metadata and statistical code will be made openly available. The data will not include any information that could make it possible to identify a given participant.Peer reviewe
Being user-oriented: convergences, divergences, and the potentials for systematic dialogue between disciplines and between researchers, designers, and providers
The challenge this panel addresses is drawn from intersecting literature reviews and critical commentaries focusing on: 1) user studies in multiple fields; and 2) the difficulties of bringing different disciplines and perspectives to bear on userâoriented research, design, and practice. 1
The challenge is that while we have made some progress in collaborative work, we have some distance to go to become userâoriented in interâdisciplinary and interâperspective ways. The varieties of our approaches and solutions are, as some observers suggest, an increasing cacophony. One major difficulty is that most discussions are solutionâoriented, offering arguments of this sort ââ if only we addressed users in this way⊠Each solution becomes yet another addition to the cacophony.
This panel implements a central approach documented for its utility by communication researchers and long used by communication mediators and negotiators ââ that of focusing not on communication but rather on metaâcommunication: communicating about communication. The intent in the context of this panel is to help us refocus attention from too frequent polarizations between alternative solutions to the possibility of coming to understand what is behind the alternatives and where they point to experientiallyâbased convergences and divergences, both of which might potentially contribute to synergies.
The background project for this panel comes from a series of inâdepth interviews with expert researchers, designers, and providers in three field groupings ââ library and information science; human computer interaction/information technology; and communication and media studies. One set of interviews involved 5âhour focus groups with directors of academic and public libraries serving 44 colleges and universities in central Ohio; the second involved oneâonâone interviews averaging 50 minutes with 81 nationallyâinternationally known experts in the 3 fields, 25â27 interviews per field. Using Dervin\u27s SenseâMaking Methodological approach to interviewing, the expert interviews of both kinds asked each interviewee: what he/she considered to be the big unanswered questions about users and what explained why the questions have not been answered; and, what he/she saw as hindering versus helping in attempts to communicate about users across disciplinary and perspective gaps. 2 The panel consists of six teams, two from each field. Prior to the panel presentation at ASIST, each team will have read the set of interviews and completed impressionistic essays of what patterns and themes they saw as emerging. At this stage, team members will purposively not homogenize their differences and most will write soloâauthored essays that will be placed on a webâsite accessible to ASIST members prior to the November meeting. In addition, at least one systematic analysis will be completed and available online. 3
At the ASIST panel, each team\u27s leader will present a brief and intentionally provocative impressionist account of what his/her team came to understand about our struggles communicating across fields and perspectives about users. Again, each team will purposively not homogenize its own differences in viewpoints, but rather highlight them as fodder for discussion. A major purpose will be to invite audience members to join the panel in discussion. At least 20 minutes will be left open for this purpose

Diet and exercise changes following direct-to-consumer personal genomic testing
Background: The impacts of direct-to-consumer personal genomic testing (PGT) on health behaviors such as diet and exercise are poorly understood. Our investigation aimed to evaluate diet and exercise changes following PGT and to determine if changes were associated with genetic test results obtained from PGT. Methods: Customers of 23andMe and Pathway Genomics completed a web-based survey prior to receiving PGT results (baseline) and 6 months post-results. Fruit and vegetable intake (servings/day), and light, vigorous and strength exercise frequency (days/week) were assessed. Changes in diet and exercise were examined using paired t-tests and linear regressions. Additional analyses examined whether outcomes differed by baseline self-reported health (SRH) or content of PGT results. Results: Longitudinal data were available for 1,002 participants. Significant increases were observed for vegetable intake (mean Î = 0.11 (95% CI = 0.05, 0.17), p = 0.0003) and strength exercise (Î = 0.14 (0.03, 0.25), p = 0.0153). When stratified by SRH, significant increases were observed for all outcomes among lower SRH participants: fruit intake, Î = 0.11 (0.02, 0.21), p = 0.0148; vegetable intake, Î = 0.16 (0.07, 0.25), p = 0.0005; light exercise, Î = 0.25 (0.03, 0.47), p = 0.0263; vigorous exercise, Î = 0.23 (0.06, 0.41), p = 0.0097; strength exercise, Î = 0.19 (0.01, 0.37), p = 0.0369. A significant change among higher SRH participants was only observed for light exercise, and in the opposite direction: Î = -0.2468 (-0.06, -0.44), p = 0.0111. Genetic results were not consistently associated with any diet or exercise changes. Conclusions: The experience of PGT was associated with modest, mostly positive changes in diet and exercise. Associations were independent of genetic results from PGT
The End Of Wilderness: Conflict And Defeat Of Wilderness In The Grand Canyon
In the early 1970s, Grand Canyon National Park intended to designate its land to Wilderness, including the controversial Colorado River corridor. However, by the end of the 1970s the potential for Wilderness designation was off the table, and would never seriously return for genuine consideration. Using Schattschneider\u27s model of conflict, we explain how the organization of this conflict privileges the causal story of Wilderness opponents, and therefore why the canyon is not designated. It is our contention that members of Congress will not stand forward to support Wilderness designations without simultaneously providing benefits for extractive land use because (1) congressional representatives are more penalized for supporting than opposing Wilderness designations, (2) Wilderness advocacy groups do not pressure congressional delegates as firmly as opposition groups, and (3) key local congressional members are not likely to see Wilderness as a salient issue worth the risk of negative exposure. If these findings hold, the implication is that we may have reached the end of significant Wilderness designations in highly visible areas, unless critical aspects in land use conflict change. © 2006 by The Policy Studies Organization

A Political Economy of Russian Nature Conservation Policy: Why Scientists have Taken a Back Seat
During the Soviet era, Soviet scientists were well respected and often included in the policy-making process. Under the new set of post-Soviet circumstances, scientists remain influential but their favored position has decreased insofar as they now operate in an expanded pluralist context in which they must join or compete with emergent local, national and international NGOs and other actors for influence. In this article, we explain this change in terms of a shift from a centralized political economy to a liberal one. A liberal political economy has allowed various groups and institutions, and the public in general, to participate in environmental policy-making. This has diminished the influence of Russian scientists. Highlighting this diminishment, we demonstrate that policy-making under a liberal framework does not always result in greater environmental protection. The article explores the implications of this for Russia and, by extension, other parts of the newly liberalizing world. Copyright (c) 2002 Massachusetts Institute of Technology.
Quality of Information in YouTube Videos on Erectile Dysfunction
INTRODUCTION: Many patients seek information online including on social media. AIM: To assess the quality of information regarding erectile dysfunction (ED) in YouTube videos. METHODS: We searched "erectile dysfunction" on YouTube in October 2019 and evaluated the first 100 videos in English sorted by relevance. MAIN OUTCOME MEASURE: We recorded the user engagement, video producer, intended audience, and content. Videos containing medical information were evaluated using the Patient Education Materials Assessment Tool (PEMAT) and the DISCERN quality criteria for consumer health information. The PEMAT evaluates the understandability and actionability of materials as a percentage. The DISCERN assesses the quality of information by a scale from 1 (serious or extensive shortcomings) to 5 (minimal shortcomings). RESULTS: The median number of total views was 22,450 (range 591-20,255,133) and the median number of views/month was 654 (range 9-723,398). 42 percent of the videos were posted by professional medical institutions, and 21% were posted by individual medical professionals. Most videos were aimed at the general public or patients suffering from ED. The median PEMAT understandability and actionability scores were both 100% (range 50-100% and 33-100%, respectively). The median DISCERN score was 2 (range 1-5) with 80.4% receiving a score of â€3. Overall, 28% of the videos contained direct misinformation. DISCERN scores were higher in videos produced by medical institutions (P = .0104), not selling specific products (P = .007) and not promoting alternative medicine (P = .0002). The number of subscribers was an independent predictor of views/month (P < .0001). CONCLUSION: Patients may be exposed to videos of poor quality when searching for information about ED on YouTube. The medical community needs to adapt a strategy to improve the quality of online medical information. Fode M, NolsĂže AB, Jacobsen FM, et al.
