Aligning conservation priorities across taxa in Madagascar with high-resolution planning tools

Globally, priority areas for biodiversity are relatively well known, yet few detailed plans exist to direct conservation action within them, despite urgent need. Madagascar, like other globally recognized biodiversity hot spots, has complex spatial patterns of endemism that differ among taxonomic groups, creating challenges for the selection of within-country priorities. We show, in an analysis of wide taxonomic and geographic breadth and high spatial resolution, that multitaxonomic rather than single-taxon approaches are critical for identifying areas likely to promote the persistence of most species. Our conservation prioritization, facilitated by newly available techniques, identifies optimal expansion sites for the Madagascar government's current goal of tripling the land area under protection. Our findings further suggest that high-resolution multitaxonomic approaches to prioritization may be necessary to ensure protection for biodiversity in other global hot spots.

Data mining approach identifies research priorities and data requirements for resolving the red algal tree of life

Background. The assembly of the tree of life has seen significant progress in recent years but algae and protists have been largely overlooked in this effort. Many groups of algae and protists have ancient roots and it is unclear how much data will be required to resolve their phylogenetic relationships for incorporation in the tree of life. The red algae, a group of primary photosynthetic eukaryotes of more than a billion years old, provide the earliest fossil evidence for eukaryotic multicellularity and sexual reproduction. Despite this evolutionary significance, their phylogenetic relationships are understudied. This study aims to infer a comprehensive red algal tree of life at the family level from a supermatrix containing data mined from GenBank. We aim to locate remaining regions of low support in the topology, evaluate their causes and estimate the amount of data required to resolve them. Results. Phylogenetic analysis of a supermatrix of 14 loci and 98 red algal families yielded the most complete red algal tree of life to date. Visualization of statistical support showed the presence of five poorly supported regions. Causes for low support were identified with statistics about the age of the region, data availability and node density, showing that poor support has different origins in different parts of the tree. Parametric simulation experiments yielded optimistic estimates of how much data will be needed to resolve the poorly supported regions (ca. 103 to ca. 104 nucleotides for the different regions). Nonparametric simulations gave a markedly more pessimistic image, some regions requiring more than 2.8 105 nucleotides or not achieving the desired level of support at all. The discrepancies between parametric and nonparametric simulations are discussed in light of our dataset and known attributes of both approaches. Conclusions. Our study takes the red algae one step closer to meaningful inclusion in the tree of life. In addition to the recovery of stable relationships, the recognition of five regions in need of further study is a significant outcome of this work. Based on our analyses of current availability and future requirements of data, we make clear recommendations for forthcoming research.

Research priorities of adult intensive care nurses in 20 European countries: a Delphi study.

Aims: This paper is a report of a three round Delphi study of intensive care nursing research priorities in Europe (October 2006–April 2009).

Background: Internationally, priorities for research in intensive care nursing have received some attention focusing on healthcare interventions and patient needs. Studies as early as the 1980s identified priorities in the United States, United Kingdom, Hong Kong and Australia. Research priorities of intensive care nurses across the European Union are unknown.

Methods: The participants, invited in 2006, included 110 intensive care nurses, managers, educators and researchers from 20 European Critical Care Nursing Associations. Delphi round one was an emailed questionnaire inviting participants to list important areas for research. The list was content analysed and developed into an online questionnaire for rounds two and three. In round two, participants ranked the topics on a scale of 1–6 (not important to extremely important). Mean scores of round two were added to the questionnaire of round three and participants ranked the topics again.

Results: There were 52 research topics in 12 domains. There was a dominance of priorities in five main areas: patient safety; impact of evidence based practice on outcomes; impact of workforce on outcomes; well being of patients and relatives; and impact of end-of-life care on staff and practice.

Conclusions: The results reflect worldwide healthcare concerns and objectives and highlight topics that nurses view as fundamental to the care of critically ill patients. These topics provide a platform for future research efforts to improve clinical practice and care of patients in intensive care.

Getting priorities straight: Risk assessment and decision-making in the improvement of inherited disorders in pedigree dogs

The issue of inherited disorders in pedigree dogs is not a recent phenomenon and reports of suspected genetic defects associated with breeding practices date back to Charles Darwin's time. In recent years, much information on the array of inherited defects has been assimilated and the true extent of the problem has come to light. Historically, the direction of research funding in the field of canine genetic disease has been largely influenced by the potential transferability of findings to human medicine, economic benefit and importance of dogs for working purposes. More recently, the argument for a more canine welfare-orientated approach has been made, targeting research efforts at the alleviation of the most suffering in the greatest number of animals.

Research priorities associated with family caregivers in palliative care:international perspectives

Reviews of the literature have consistently highlighted significant gaps with regard to research associated with family caregivers within the context of palliative care. We sought to determine a priority driven research agenda for this field of inquiry.

Identifying research priorities in long term care homes

Concerns about the quality of care in long term care (LTC) homes range from inadequate daily care to understaffing and insufficient funding. LTC decision makers are challenged to keep up with the changing demographics of residents admitted to LTC who have increasingly complex care needs. Decisions regarding LTC policies and procedures need to be informed by research that identifies the most effective and efficient care practices.This study solicited feedback from LTC decision makers in Ontario, Canada, regarding research priorities to guide improvement in the quality of care in LTC homes. Representatives from 134 LTC homes responded (53.6% response rate). Nine thematic areas of research were identified: delivery of care; staffing; organization and structure of homes; funding; indicators, standards, policies, and procedures; managing difficult behaviors; education; safety; and infectious disease control. It is anticipated that these themes will steer research down a path that is responsive to the information needs of practitioners in LTC homes. © 2012 American Medical Directors Association, Inc.

Identifying research priorities on infections in older adults:Proceedings of an interdisciplinary workshop

Background: Infections pose a substantial burden to the health of older adults. In this report, we describe the proceedings of a workshop to formulate and prioritize research questions about infections in older adults using an interdisciplinary approach. Methods: Researchers from four sectors (basic science, clinical sciences, health services and epidemiology/determinants of health) and representatives from various Canadian local, provincial, and federal stakeholder groups were invited to a two-day workshop. Five multi-disciplinary groups and stakeholders from each of three healthcare settings (long term, acute care and community) discussed research priorities for each of the settings. Five to ten research questions were identified for each setting. Results: The research questions proposed ranged from risk factors and outcomes for different infections to the effect of nutrition on infection and the role of alternative and complementary medicine in treating infections. Health service issues included barriers to immunization, prolongation of hospital length of stay by infection, use of care paths for managing infections, and decision-making in determining the site of care for individuals with infections. Clinical questions included risk factor assessment for infection, the effectiveness of preventative strategies, and technology evaluation. Epidemiologic issues included the challenge of achieving a better understanding of respiratory infections in the community and determining the prevalence of colonization with multi-resistant bacteria. Conclusions: The questions are of direct relevance to researchers in a wide variety of fields. Bringing together a multi-disciplinary group of researchers to frame and prioritize research questions about aging is feasible, participants valued the opinions of people working in other areas.

Evaluation of quality of life and priorities of patients with glaucoma

PURPOSE: To investigate the quality of life and priorities of patients with glaucoma.

METHODS: Patients diagnosed with glaucoma and no other ocular comorbidity were consecutively recruited. Clinical information was collected. Participants were asked to complete three questionnaires: EuroQuol (EQ-5D), time tradeoff (TTO), and choice-based conjoint analysis. The latter used five-attribute outcomes: (1) reading and seeing detail, (2) peripheral vision, (3) darkness and glare, (4) household chores, and (5) outdoor mobility. Visual field loss was estimated by using binocular integrated visual fields (IVFs).

RESULTS: Of 84 patients invited to participate, 72 were enrolled in the study. The conjoint utilities showed that the two main priorities were "reading and seeing detail" and "outdoor mobility." This rank order was stable across all segmentations of the data by demographic or visual state. However, the relative emphasis of these priorities changed with increasing visual field loss, with concerns for central vision increasing, whereas those for outdoor mobility decreased. Two subgroups of patients with differing priorities on the two main attributes were identified. Only 17% of patients (those with poorer visual acuity) were prepared to consider TTO. A principal component analysis revealed relatively independent components (i.e., low correlations) between the three different methodologies for assessing quality of life.

CONCLUSIONS: Assessments of quality of life using different methodologies have been shown to produce different outcomes with low intercorrelations between them. Only a minority of patients were prepared to trade time for a return to normal vision. Conjoint analysis showed two subgroups with different priorities. Severity of glaucoma influenced the relative importance of priorities.
