Systematic scoping review protocol of Stroke Patient and Stakeholder Engagement (SPSE).

This protocol describes a systematic scoping review of Stroke Patient and Stakeholder Engagement (SPSE), concepts, definitions, models, implementation strategies, indicators, or frameworks. The active engagement of patients and other stakeholders is increasingly acknowledged as essential to patient-centered research to answer questions of importance to patients and their caregivers. Stroke is a debilitating, long-lasting burden for individuals, their families, and healthcare professionals.

Reporting of patient involvement: a mixed-methods analysis of current practice in health research publications using a targeted search strategy.

Objectives: To evaluate the extent and quality of patient involvement reporting in examples of current practice in health research.

Design: Mixed-methods study. We used a targeted search strategy across three cohorts to identify health research publications that reported patient involvement: original research articles published in 2019 in the British Medical Journal (BMJ), articles listed in the Patient-Centered Outcomes Research Institute (PCORI) database (2019), and articles citing the GRIPP2 (Guidance for Reporting Involvement of Patients and Public) reporting checklist for patient involvement or a critical appraisal guideline for user involvement.

Finding the best fit for improving reproducibility: reflections from the QUEST Center for Responsible Research.

Increasing the reproducibility and trustworthiness of biomedical research requires engaging stakeholders from all levels in an institutional setting. The QUEST Center for Responsible Research aims to develop and implement new approaches to improve the culture and practice of research, tailored to the needs of these stakeholders. Members of the QUEST Center organised a brainstorm to reflect on the challenges and new opportunities encountered in implementing different projects through QUEST and share the lessons that working groups have learned over the first five years.

Stakeholder involvement in dementia research: A qualitative approach with healthy senior citizens and providers of dementia care in Germany.

Engaging stakeholders in health-related research is becoming commonplace internationally and is increasingly considered best research practice to improve care management services. Many different groups have a stake in dementia care, but the evidence base for stakeholder involvement in dementia research is still small. The aim of this study was to explore views of two major stakeholder groups of dementia care in research priority setting and how they would want to be involved in dementia research.

No association of cortical amyloid load and EEG connectivity in older people with subjective memory complaints.

Changes in functional connectivity of cortical networks have been observed in resting-state EEG studies in healthy aging as well as preclinical and clinical stages of AD. Little information, however, exists on associations between EEG connectivity and cortical amyloid load in people with subjective memory complaints. Here, we determined the association of global cortical amyloid load, as measured by florbetapir-PET, with functional connectivity based on the phase-lag index of resting state EEG data for alpha and beta frequency bands in 318 cognitively normal individuals aged 70-85 years with subjective memory complaints from the INSIGHT-preAD cohort.

Cortical amyloid accumulation is associated with alterations of structural integrity in older people with subjective memory complaints.

We determined the effect of cortical amyloid load using F-florbetapir PET on cognitive performance and gray matter structural integrity derived from MRI in 318 cognitively normally performing older people with subjective memory impairment from the INSIGHT-preAD cohort using multivariate partial least squares regression. Amyloid uptake was associated with reduced gray matter structural integrity in hippocampus, entorhinal and cingulate cortex, middle temporal gyrus, prefrontal cortex, and lentiform nucleus (p < 0.01, permutation test).

Being low prepares for being neglected: Verticality affects expectancy of social participation.

Previous research suggests that the established link of vertical position and self-assignment of social power affects the processing of social exclusion. We hypothesized that verticality-induced self-assignment of social power moderates the evaluation of exclusion via a change in subjective expectancy of social participation. Following this idea, a superior position-associated with higher power-was supposed to increase the sensitivity for a transition to social exclusion.

Target and Non-Target Processing during Oddball and Cyberball: A Comparative Event-Related Potential Study.

The phenomenon of social exclusion can be investigated by using a virtual ball-tossing game called Cyberball. In neuroimaging studies, structures have been identified which are activated during social exclusion. But to date the underlying mechanisms are not fully disclosed.

ERP effects and perceived exclusion in the Cyberball paradigm: Correlates of expectancy violation?

A virtual ball-tossing game called Cyberball has allowed the identification of neural structures involved in the processing of social exclusion by using neurocognitive methods. However, there is still an ongoing debate if structures involved are either pain- or exclusion-specific or part of a broader network. In electrophysiological Cyberball studies we have shown that the P3b component is sensitive to exclusion manipulations, possibly modulated by the probability of ball possession of the participant (event "self") or the presumed co-players (event "other").

Are there benefits of social overinclusion? Behavioral and ERP effects in the Cyberball paradigm.

Social participation can be examined using the Cyberball paradigm, a virtual ball-tossing game. Reducing the involvement of the participant is supposed to activate a neural alarm system, and to threaten fundamental social needs. Our previous findings indicate that the latter process can be linked to an enhancement of the centro-parietal P3 amplitude, signaling a modulation of the subjective expectancy of involvement.

The effect of the physical presence of co-players on perceived ostracism and event-related brain potentials in the cyberball paradigm.

The affective and cognitive mechanisms elicited by the experience of social exclusion-or ostracism-have recently been explored using behavioral and neurocognitive methods. Most of the studies took advantage of the Cyberball paradigm, a virtual ball tossing game with presumed co-players connected via the internet. Consistent behavioral findings indicate that exclusion obviously threatens fundamental social needs (belonging, self-esteem, meaningful existence, and control) and lowers mood.

Differential effects of moderate alcohol consumption on motion and contrast processing.

Although a moderate blood alcohol concentration already affects attention, an effect on early visual processing is still questionable. Using psychophysical measures and visually evoked potentials (VEP), we examined the effects of alcohol on the processing of contrast and motion features. In our tasks, two lateralized stimuli were briefly presented, and participants had to identify either the stimulus of higher contrast or motion coherence.
