Quantifying habitat preference of bottom trawling gear
Continental shelves around the world are subject to intensive bottom trawling. Demersal fish assemblages inhabiting these shelves account for one-fourth of landed wild marine species. Increasing spatial claims for nature protection and wind farm energy suppresses, however, the area available to fisheries. In this marine spatial planning discussion, it is essential to understand what defines suitable fishing grounds for bottom trawlers. We developed a statistical methodology to study the habitat preference of a fishery, accounting for spatial correlation naturally present in fisheries data using high-resolution location data of fishing vessels and environmental variables. We focused on two types of beam trawls to target sole using mechanical or electrical stimulation. Although results indicated only subtle differences in habitat preference between the two gear types, a clear difference in spatial distribution of the two gears was predicted. We argue that this change is driven by both changes in habitat preference as well as a change in target species distribution. We discuss modelling of fisheries' habitat preference in light of marine spatial planning and as support in benthic impact assessments.</p
Personal health communities: A phenomenological study of a new health-care concept
Context: Fragmentation of care, complexity of diseases and the need to involve patients actively in their individual health care led to the development of the personal health community (PHC). In a PHC, patients can -regardless of the nature of their condition- invite all professionals that are involved in their health care process. Once gathered, the patient and health care team can exchange information about the patient's health and communicate through several functionalities, in a secured environment. Objectives: Exploring the use, first experiences and potential consequences of using PHCs in health care. Design: Qualitative phenomenological study. Participants: Eighteen respondents, consisting of women experiencing infertility (n = 5), persons with Parkinson's disease (n = 6), a gynaecologist, a fertility doctor, a fertility nurse, three Parkinson's specialist nurses and a neurologist. Results: First experiences with PHCs showed that patients use their PHC differently, dependending on their condition and people involved. Various (potential) advantages for future health care were mentioned relating to both organizational aspects of care (e.g. continuity of care) and the human side of care (e.g. personal care). Patient involvement in care was facilitated. Disadvantages were the amount of work that it took and technological issues. Conclusions: Using PHCs leads to promising improvements in both the organization of care and care experience, according to the participants in this study. They indicate that patients with different diseases and in different circumstances can benefit from these improvements. The PHC seem to be an online tool that can be applied in a personalized way. When (technically) well facilitated, it could stimulate active involvement of patients in their own health and health care. It warrants further research to study its effect on concrete health outcomes
Assessing medical student knowledge and attitudes about shared decision making across the curriculum: protocol for an international online survey and stakeholder analysis
Introduction: Shared decision making (SDM) is a goal of modern medicine; however, it is not currently embedded in routine care. Barriers include clinicians’ attitudes, lack of knowledge and training and time constraints. Our goal is to support the development and delivery of a robust SDM curriculum in medical education. Our objective is to assess undergraduate medical students’ knowledge of and attitudes towards SDM in four countries.
Methods and analysis: The first phase of the study involves a web-based cross-sectional survey of undergraduate medical students from all years in selected schools across the United States (US), Canada and undergraduate and graduate students in the Netherlands. In the United Kingdom (UK), the survey will be circulated to all medical schools through the UK Medical School Council. We will sample students equally in all years of training and assess attitudes towards SDM, knowledge of SDM and participation in related training. Medical students of ages 18 years and older in the four countries will be eligible. The second phase of the study will involve semistructured interviews with a subset of students from phase 1 and a convenience sample of medical school curriculum experts or stakeholders. Data will be analysed using multivariable analysis in phase 1 and thematic content analysis in phase 2. Method, data source and investigator triangulation will be performed. Online survey data will be reported according to the Checklist for Reporting the Results of Internet E-Surveys. We will use the COnsolidated criteria for REporting Qualitative research for all qualitative data.
Ethics and dissemination: The study has been approved for dissemination in the US, the Netherlands, Canada and the UK. The study is voluntary with an informed consent process. The results will be published in a peer-reviewed journal and will help inform the inclusion of SDM-specific curriculum in medical education worldwide
Medical students’ knowledge and attitudes towards shared decision-making: results from a multinational cross-sectional survey
Introduction: We aimed to conduct a multinational cross-sectional online survey of medical students' attitudes towards, knowledge of, and experience with shared decision-making (SDM).
Methods: We conducted the survey from September 2016 until May 2017 using: 1) a convenience sample of students from four medical schools each in Canada, the US, and the Netherlands (n=12), and 2) all medical schools in the UK through the British Medical School Council (n=32). We also distributed the survey through social media.
Results: 765 students read the information sheet and 619 completed the survey. Average age was 24, 69% were female. Mean SDM knowledge score was 83.6% (range:18.8%-100%; 95% CI 82.8%-84.5%). US students had the highest knowledge scores (86.2%, 95% CI 84.8%-87.6%). The mean risk communication score was 57.4% (range: 0%-100%; 95% CI 57.4%-60.1%). Knowledge did not vary with age, race, gender, school, or school year. Attitudes were positive, except 46% believed SDM could only be done with higher educated patients and 80.9% disagreed that physician payment should be linked to SDM performance (increased with years in training, p<.05). Attitudes did not vary due to any tested variable. Students indicated they were more likely than experienced clinicians to practice SDM (72.1% vs. 48.8%). 74.7% reported prior SDM training and 82.8% were interested in learning more about SDM.
Discussion: SDM knowledge is high among medical students in all four countries. Risk communication is less well-understood. Attitudes indicate that further research is needed to understand how medical schools deliver and integrate SDM training into existing curricula
Properties of hot and dense matter from relativistic heavy ion collisions
We review the progress achieved in extracting the properties of hot and dense
matter from relativistic heavy ion collisions at the relativistic heavy ion
collider (RHIC) at Brookhaven National Laboratory and the large hadron collider
(LHC) at CERN. We focus on bulk properties of the medium, in particular the
evidence for thermalization, aspects of the equation of state, transport
properties, as well as fluctuations and correlations. We also discuss the
in-medium properties of hadrons with light and heavy quarks, and measurements
of dileptons and quarkonia. This review is dedicated to the memory of Gerald E.

Design Multistage consultation process.
Setting Key informant group, communities of interest, and survey of clinical specialties.
Participants 19 key informants, 153 member responses from multiple communities of interest, and 316 responses to an online survey from medically qualified clinicians from six specialties.
Results After extended consultation over three iterations, we revised the three-talk model by making changes to one talk category, adding the need to elicit patient goals, providing a clear set of tasks for each talk category, and adding suggested scripts to illustrate each step. A new three-talk model of shared decision making is proposed, based on “team talk,” “option talk,” and “decision talk,” to depict a process of collaboration and deliberation. Team talk places emphasis on the need to provide support to patients when they are made aware of choices, and to elicit their goals as a means of guiding decision making processes. Option talk refers to the task of comparing alternatives, using risk communication principles. Decision talk refers to the task of arriving at decisions that reflect the informed preferences of patients, guided by the experience and expertise of health professionals.
Conclusions The revised three-talk model of shared decision making depicts conversational steps, initiated by providing support when introducing options, followed by strategies to compare and discuss trade-offs, before deliberation based on informed preferences
In vivo Recording Quality of Mechanically Decoupled Floating Versus Skull-Fixed Silicon-Based Neural Probes
Throughout the past decade, silicon-based neural probes have become a driving force in neural engineering. Such probes comprise sophisticated, integrated CMOS electronics which provide a large number of recording sites along slender probe shanks. Using such neural probes in a chronic setting often requires them to be mechanically anchored with respect to the skull. However, any relative motion between brain and implant causes recording instabilities and tissue responses such as glial scarring, thereby shielding recordable neurons from the recording sites integrated on the probe and thus decreasing the signal quality. In the current work, we present a comparison of results obtained using mechanically fixed and floating silicon neural probes chronically implanted into the cortex of a non-human primate. We demonstrate that the neural signal quality estimated by the quality of the spiking and local field potential (LFP) recordings over time is initially superior for the floating probe compared to the fixed device. Nonetheless, the skull-fixed probe also allowed long-term recording of multi-unit activity (MUA) and low frequency signals over several months, especially once pulsations of the brain were properly controlled
