The Experiences of Persons Living with Dementia Planning for a Dementia Research Meeting. Lessons Learned From the National Research Summit on Care, Services, and Supports for Persons With Dementia and Their Caregivers.

OBJECTIVE: A stakeholder group for persons living with dementia (PLWD) was convened to support the work of a major US dementia research meeting. The objectives of this examination are to present the steps used to implement the Group and guidance for both PLWD and researchers for partnering on research conference planning and participation. METHODS: PLWD met monthly to provide input into the agenda for the 2017 Research Summit on Dementia Care and some Group members also presented at the Summit. Following the Summit, the Group reviewed their contributions and completed an evaluation of the Group process, identifying best practices to support future efforts. RESULTS: Group members were initially unsure about participating due to concerns about ability to contribute and concerns about disease progression. Members reported that participation was a positive experience, however, identifying Group-led governance and attention to Group work process as important contributors. In addition to giving input to the Summit and having the opportunity to interact with researchers, sharing personal experiences with each other was part of the value of the Group to members. Careful Group selection and attention to governance were among the Best Practices members. CONCLUSION: Despite initial uncertainty among members about participating as a Stakeholder Group to inform a national research meeting, members developed a successful process for governance, convening, and providing input to a major national research meeting. Group's self-evaluation yielded specific strategies likely to be useful in formation and implementation of future partnerships between researchers and persons living with dementia.

Contributions of Persons Living With Dementia to Scientific Research Meetings. Results From the National Research Summit on Care, Services, and Supports for Persons With Dementia and Their Caregivers.

OBJECTIVE: Inclusion of patients in research activities has increased in the United States but no guidelines for inclusion of individuals with cognitive impairment exist. The experiences from the Persons Living with Dementia (PLWD) Stakeholder Group that formed to support the first National Research Summit on Care, Services, and Supports for Persons with Dementia and Their Caregivers provided a test of feasibility of this type of participation for a major research meeting and an opportunity to understand specific contributions of the Group. METHODS: The PLWD Stakeholder Group was formed by Summit co-chairs as one of six stakeholder groups charged with providing input into the Summit agenda and meeting recommendations. Members were recruited through clinician/researchers with personal knowledge of potential members. Following the Summit, Group members convened to review Group contributions to the Summit agenda, list of speakers, and Summit research recommendations. RESULTS: The PLWD Group influenced the content of the Summit agenda and some Group members were invited to contribute through Summit presentations. The Group influenced Summit outcomes: of the 58 research recommendations that emerged, 30 express ideas contributed by the PLWD. CONCLUSIONS: The Stakeholder Group for PLWD proved feasible to implement and impacted the agenda and output of a major national research meeting on dementia.

Genome-Wide Screens Reveal New Gene Products That Influence Genetic Competence in Streptococcus mutans.

A network of genes and at least two peptide signaling molecules tightly control when Streptococcus mutans becomes competent to take up DNA from its environment. Widespread changes in the expression of genes occur when S. mutans is presented with competence signal peptides in vitro, including the increased production of the alternative sigma factor, ComX, which activates late competence genes. Still, the way that gene products that are regulated by competence peptides influence DNA uptake and cellular physiology are not well understood. Here, we developed and employed comprehensive transposon mutagenesis of the S. mutans genome, with a screen to identify mutants that aberrantly expressed comX, coupled with transposon sequencing (Tn-seq) to gain a more thorough understanding of the factors modulating comX expression and progression to the competent state. The screens effectively identified genes known to affect competence, e.g., comR, comS, comD, comE, cipB, clpX, rcrR, and ciaH, but disclosed an additional 20 genes that were not previously competence associated. The competence phenotypes of mutants were characterized, including by fluorescence microscopy to determine at which stage the mutants were impaired for comX activation. Among the novel genes studied were those implicated in cell division, the sensing of cell envelope stress, cell envelope biogenesis, and RNA stability. Our results provide a platform for determining the specific chemical and physical cues that are required for genetic competence in S. mutans, while highlighting the effectiveness of using Tn-seq in S. mutans to discover and study novel biological processes.IMPORTANCEStreptococcus mutans acquires DNA from its environment by becoming genetically competent, a physiologic state triggered by cell-cell communication using secreted peptides. Competence is important for acquiring novel genetic traits and has a strong influence on the expression of virulence-associated traits of S. mutans Here, we used transposon mutagenesis and genomic technologies to identify novel genes involved in competence development. In addition to identifying genes previously known to be required for comX expression, 20 additional genes were identified and characterized. The findings create opportunities to diminish the pathogenic potential of S. mutans, while validating technologies that can rapidly advance our understanding of the physiology, biology, and genetics of S. mutans and related pathogens.

A great American psychiatrist reconsidered. Commentary on "Neuropsychiatric sequelae of cerebral trauma in children", by Edward A. Strecker and Franklin G. Ebaugh.

In a seminal article from the early twentieth century, a vivid picture was painted of the psychiatric outcomes of child head injury. Reading this now, the insights to be derived are considerable.

Analysis of a database of materials for HIV prevention program evaluation.

Program evaluation technology transfer is the transfer of information on program evaluation from research to practitioners. There have been anecdotal reports of a lack of technology transfer materials related to HIV prevention program evaluation, especially materials usable by persons without extensive training in evaluation. The Centers for Disease Control and Prevention reviewed available program evaluation materials relevant to HIV prevention and developed a database of those materials. Materials were classified according to appropriate audience, level of evaluation expertise required, steps in the evaluation process addressed, and other criteria. The database was queried to determine the number of materials available for various combinations of search criteria. These queries revealed that for certain audiences and steps in the evaluation process there are few materials, especially usable by individuals without evaluation experience. The conclusion is that for certain areas of program evaluation, and for certain audiences, more evaluation technology transfer materials are needed.
