Survey of public attitudes towards imminent death donation in the United States.

Imminent death donation (IDD) is described as living organ donation prior to a planned withdrawal of life-sustaining care in an imminently dying patient. Although IDD was ethically justified by United Network for Organ Sharing, the concept remains controversial due to presumed lack of public support. The aim of this study was to evaluate the public's attitudes towards IDD. A cross-sectional survey was conducted of US adults age >18 years (n = 2644). The survey included a case scenario of a patient with a devastating brain injury. Responses were assessed on a 5-point Likert scale. Results showed that 68% - 74% of participants agreed or strongly agreed with IDD when posed as a general question and in relation to the case scenario. Participants were concerned about "recovery after a devastating brain injury" (34%), and that "doctors would not try as hard to save a patient's life" (33%). Only 9% of participants would be less likely to trust the organ donation process. In conclusion, our study demonstrates strong public support for IDD in the case of a patient with a devastating brain injury. Notably, participants were not largely concerned with losing trust in the organ donation process. These results justify policy change towards imminent death donation.

Spatial Variation and Survival of Salmonella enterica Subspecies in a Population of Australian Sleepy Lizards (Tiliqua rugosa).

The life cycles of many enteric bacterial species require a transition between two very distinct environments. Their primary habitat is the gastrointestinal tract of the host, while their secondary habitat, during transmission from one host to another, consists of environments external to the host, such as soil, water, and sediments. Consequently, both host and environmental factors shape the genetic structure of enteric bacterial populations. This study examined the distribution of four Salmonella enterica subspecies in a population of sleepy lizards, Tiliqua rugosa, in a semiarid region of South Australia. The lizards living within the 1,920-m by 720-m study site were radio tracked, and their enteric bacteria were sampled at regular intervals throughout their active seasons in the years 2001, 2002, and 2006. Four of the six subspecies of S. enterica were present in this population and were nonrandomly distributed among the lizards. In particular, S. enterica subsp. diarizonae was restricted to lizards living in the most shaded parts of the study site with an overstorey of Casuarina trees. Experiments undertaken to investigate the survival of S. enterica cells under seminatural conditions revealed that cell survival decreased with increased exposure to elevated temperatures and UV light. Among the three S. enterica subspecies tested, S. enterica subsp. diarizonae consistently had an average expected life span that was shorter than that observed for the other two subspecies. There was no indication in the data that there was any competitive dominance hierarchy among the S. enterica subspecies within individual hosts. Thus, the nonrandom distribution of S. enterica subspecies in this population of lizards appears to be driven by their different survival characteristics in the external environment.

Healthcare Worker Attitudes to Living Donation Prior to Planned Withdrawal of Care.

Background and Aims: This study assesses the attitudes of healthcare practitioners toward Living Donation Prior to Planned Withdrawal of Care (LD-PPW): the recovery of a living donor organ before withdrawal of life-sustaining measures in a patient who does not meet criteria for brain death, but for whom medical care toward meaningful recovery is deemed futile. Methods: An electronic survey was administered to 1735 members of the American Society of Transplant Surgeons mailing list with 187 responses (10.8%). Results: Data from this study revealed that 70% of responding practitioners agreed with LD-PPW due to principles of beneficence and autonomy. Also, 65% of participants felt confident in their ability to declare the futility of care and 70% felt that LD-PPW should be added as an option when registering to become an organ donor. Conclusion: Currently, nearly half of all donation after circulatory determination of death do not proceed to donation. LD-PPW has been proposed as an alternative procedure targeted at increasing the quality and quantity of transplantable organs while respecting the donor's right to donate, though its implementation has been hindered by concerns over public and provider perception. This study revealed support for LD-PPW among healthcare practitioners as an alternative procedure to increase the quality and quantity of transplantable organs while respecting the donor's right to donate.

Substructure within Salmonella enterica subsp. enterica isolates from Australian wildlife.

Multilocus sequence typing of 56 Salmonella enterica subsp. enterica strains isolated from Australian wildlife hosts was performed. The results of population assignment algorithms revealed that the 56 strains could be subdivided into two distinct clades. Strains belonging to the two clades were further distinguished phenotypically, genotypically, and with respect to host distribution.

Family Practice Nursing in Newfoundland and Labrador: Are Reported Roles Reflective of Professional Competencies for Registered Nurses in Primary Care?

BACKGROUND: Family practice nurses are Registered Nurses who work collaboratively in primary care and deliver a range of services. Professional competency statements have been developed to describe the skills and knowledge of family practice nurses as a distinct field. PURPOSE: We conducted a secondary analysis of qualitative interview data to examine how family practice nurse roles/activities relate to recently developed professional competencies. METHODS: Family physicians and family practice nurses in Newfoundland and Labrador (NL) participated in semi-structured interviews, during which they discussed roles/activities and scope of practice surrounding family practice nursing. For this secondary analysis, we used competency statements to inform thematic coding of the transcribed interviews. RESULTS: For the initial study, a total of 8 participants (5 family practice nurses; 3 family physicians) were interviewed from diverse practices. All transcripts from the original study (n = 8) were included in the secondary analysis and analysed across 47 competencies encompassing 6 domains (Professionalism; Clinical Practice; Communication; Collaboration and Partnership; Quality Assurance, Evaluation and Research; Leadership). Roles/activities reported by participants were reflective of the competencies, but with substantial variation in expression. CONCLUSIONS: Family practice nursing competency statements reflect the actual activities of family practice nurses in NL. The professional competencies can serve as a framework to examine contributions of family practice nurses and identify areas warranting further training. The use of competencies to explore family practice nurses' roles and activities can assist with optimizing scope of practice.

Evaluation plan of the 6for6 research skills program for rural and remote physicians.

Overwhelming issues and barriers often prevent rural and remote physicians (RRPs) from pursuing the many socially accountable research questions they encounter on a daily basis. Although research training programs can empower RRPs to rise to these challenges, there is a lack of evidence on how they should be developed and refined. At Memorial University, a faculty development program (FDP) called 6for6 has been helping RRPs surmount their research quagmires and engage in scholarship since 2014. After an initial three-year (2014-17) pilot, we prepared a detailed plan to evaluate the 6for6 research FDP for RRPs and inform future years of delivery. Using a modified Delphi method and participatory action model a group of program team members, stakeholders and evaluation experts developed an evaluation plan including a logic model and an evaluation matrix addressing five key themes. To our knowledge, this is the first evaluation plan for a research-focused FDP targeting RRPs. While this plan was developed specifically for the 6for6 FDP, our approach to its development may be useful to any institution interested in evaluating an FDP with limited resources.

A qualitative study exploring the influence of clinic funding on the integration of family practice nurses in Newfoundland and Labrador.

AIM: This study explores the contributions of family practice nurses in primary care across Newfoundland and Labrador funded by fee-for-service and alternate payment plans to examine the influence of funding arrangements on nursing roles/activities. DESIGN: A qualitative descriptive design was employed. METHODS: Semi-structured telephone interviews were conducted between March-July 2018 with physicians and Registered Nurses working in primary care settings in Newfoundland and Labrador. Interviews were transcribed verbatim, and a content analysis approach was used to identify recurring themes. RESULTS: Clinic funding was instrumental in the integration of family practice nurses into primary care settings and influenced roles/activities. In fee-for-service practices, nurses work with physicians and focus on one-on-one patient care in office-based settings, whereas nurses in alternate payment plans practices work more independently, in a wider range of settings and with emphasis on both individual and group-based encounters. Compared with alternate payment plans practices, fee-for-service practices tend to be more restrictive due to physician billing requirements.

Low prevalence of Salmonella enterica in Australian wildlife.

A total of 2489 wildlife hosts from Australia were sampled in order to determine the fraction of hosts that harboured Salmonella enterica as a dominant member of the host's enteric community. Hosts sampled included fish, frogs, reptiles, birds and mammals from the four main climatic regions of Australia: desert, grassland, temperate and tropical. Salmonella enterica was predominately isolated from reptiles, in particular, lizards. It was also isolated from mammals, though not from any fish, frog or bird host. Salmonella enterica was more likely to be isolated from lizards living in desert or grassland regions of Australia compared with lizards inhabiting tropical or temperate regions. The low prevalence of S. enterica isolated from wildlife hosts in Australia indicates that Australian wildlife are unlikely to play a large role in disseminating S. enterica to humans and livestock.
